Balance scooter Lets children to put down their phones

A few days ago, The 3rd China Self balancing scooter Sports Performance Competition was held in Baoding, Hebei Provinc. On the court, the players performed well and the unique moments left on the field showed the unique charm of self balancing electric scooter.

But unlike the past, these players will play well after only four days of rigorous training.

The difficulty of getting started with a twisted car is lower than that of a unicycle. However, it takes four days to complete the competition, and the skill requirements of the players are quite high. Many attendees and parents said that it was the first time to see such a national balance car race, which was very fresh and very shocking.

However, interviews were also conducted with some of the live audiences as well as the contestants and parents. What do they think of the new entertainment tools of the hoverboard smart balance scooter? What do they think about the balance car contest? Do they think that balancing cars is a dangerous sport?

In the interview, we found that most of the contestants are about ten years old, and some of them have only one or two days of training time before the competition, which is not easy.

Most of the contestants' parents think that it is not only a kind of entertainment for children to play smart self balancing scooter, but more importantly, through such a sport, children can enjoy outdoor activities. In their spare time, children can go out to go to work. Instead of just staying at home and playing mobile phones to watch TV, this is very helpful for the development of physical and mental health.

Not only the parents of the contestants, but also the audience who came to watch the game, they also agreed to the balance car, and they thought that the balance car is a sport that is very suitable for children to play.

However, so far, there are still many people who are not aware of the balance car, and think that balancing the car is a dangerous sport.

On this issue, Koowheel also conducted an interview on the spot.

One of the women said that she believes that playing balance car is also a good exercise for her own balance ability. When the balance ability is still lacking, the balance car can exercise balance. As long as the safety measures are taken, they can Control is not dangerous. She expressed her support for such activities. Since the children are still young, if there is an opportunity in the future, they will definitely encourage their children to participate in such activities.

Through this competition, many people on the scene have a deeper understanding of the balance car, and we also hope to see more parents in the future can encourage children to actively participate in such events.

Many parents have a supportive attitude towards children playing balance cars. They believe that the hoverboard smart balance scooter movement is also enriching the children's outdoor activities while cultivating the children's interests, which can also be to some extent Overcome the reliance on mobile phones.

Lithium’s safety could be the development problem of hoverboard industry

Survey found that the current cheap electric scooters, flooding the market. Reporter view electric self balancing scooter selling in taobao , the product covers hundreds of yuan is the highest price ten thousand yuan. Search keyword "self balancing electric scooter" that shows all categories of a total of 66900 pieces of baby, the price is in 1000 yuan and the baby amount to 44500, accounting for 67% of the cars sold in balance car quantity; Price is in 2000 yuan the following baby number to 55800, 83% of the number of cars sold in balancing scooter.

In the recent Hong Kong, China and Britain in the balance car charge explosion accident, according to consumer statements, the self balancing scooter price is within 2000 yuan.

Lithium battery is the power source of the current mainstream balanced car use, "the most cheap, fake balanced car products for cost savings will use some unknown battery, this is one of the important reasons causing safety concerns." researcher Li Hu told the China business news "reporter in an interview.

In shenzhen area, there are hundreds of balance car manufacturing not only factory, there are a lot of balance car battery production of small workshops.

China's chemical and physical power industry association information department told the China business news reporter, balanced car market is small, use the battery quantity is too small, large battery manufacturers are not willing to step in; Balance of sell like hot cakes, and so did the car battery sell like hot cakes, to balance the car battery production operations were brought to life.

Industry, said the balance car industry chain, battery industry and balance the car industry, there is the lack of industry standards, policies, laws and regulations is not sound, these gave speculators to claim.

Information department, according to China's chemical and physical power industry association as a result of domestic battery industry basic no regulation, battery manufacturer to purchase batteries entirely by conscience. In terms of batteries used for balance  car, poor quality of good quality batteries and battery core doubled in price difference, some defective goods price will be lower. And some balance scooter manufacturers to reduce costs, timely delivery, quality requirements for battery will ease a lot.

According to China's chemical and physical power supply the information provided by the ministry of information industry association, a balanced car battery to use good quality batteries, such as China Koowheel, they use samsung original battery, also some people said that the products using imported advanced lithium-ion batteries. 

But as the core component of balanced car batteries, generally wrapped inside the fuselage, whatever business brand, even if consumers after the purchase, is also unable to distinguish the battery quality. This information is derived from www.koowheel.com

Is the balance scooter a ghost killer on the road?

Survey found that, like electric bike, smart self balancing scooter with the motor drive, basic no sound in the process of driving, and the speed quickly, to pose a big security hidden danger in front of pedestrians, especially the old man and the child. "Ghost killer is not too much, every time I see from the smart balance wheel scooter whizzing around them, the heart is the mess, just like electric bike, don't have any sound, rather abruptly leapt from behind, very scary.

Answer to the question of the intelligent balance road driving around traffic administration has issued a ban. As early as the end of 2014, Shanghai, wuhan, Beijing and other places of the traffic administration gradually show the position of the same: electric self balancing scooter is prohibited, electric scooters and other kinds of new type vehicles on the road, it is prohibited to carry on the subway. The Beijing traffic administration, said that electric scooter is a kind of new car, driven by a power plant, used for personnel take use of wheeled vehicles. From the existing laws and regulations, the car has the “road traffic safety law ” the provisions of motor vehicles characteristics. Motor vehicles must be approved by the competent authorities of the state motor vehicle license production, according to the law to permit the registration of the road before the road. Therefore, electric self balancing scooter, electric skateboard may not be on the road. Shanghai traffic administration of public reason is that according to the regulations of Shanghai non-motor vehicles management method, has no way two wheeled scooter, shall not run on road.
The balance car is also prohibited on road in Britain and Australia . Why is there such a ban?after the banning, what will be the impact of the development of the electric self balancing scooter? The reason for the ban on the road, mainly electric balance car if the occurrence of Spontaneous Combustion Accident, can cause great damage to the surrounding crowd and environment. Electric scooter is a mainstream trend in intelligent travel. After the ban, will seriously hit the enthusiasm of production of self balancing electric scooter, to continue develop, the producers will improve production technology, to ensure the safety of products, as the market scope of narrow, manufacturing enterprises or will be faced with superior inferior to shuffle again.

The applications of Balanced car charger

The choose of hoverboard charger is very important. If you choose some low quality charger, it is possibly to bring potential safety hazard. Now let us identify the different between hoverboard scooter brand charger and inferior charger.

The Self Balancing Electric Scooter charger can be said to be a more important parts of the external.

That power charger adapter, also known as external power supply (switching power adapter), which is a small portable electronic equipment and electrical and electronic power transformer, it arises because in real life, the electronic device is often not directly use household electricity, because the family used a 220V power supply voltage, and universal electronic products are generally much smaller than the supply voltage required for this value. So the role of the power adapter is crucial, especially if you go to the United States and other countries, and our different voltage, it is more necessary 220V to 110V the transformer. With it, we can easily and safely use these electronic products.

Composition and Application charger

Power adapters common to all types of electronic products, generally by the shell, power transformer and rectifier circuit, its output can be divided into AC output type and DC output type; connections can be divided by the Wall and desktop. Electronic products of a large space, power adapter are generally built, but due to the general volume is not small adapter, a small volume of electronic products are external, such as balancing the car, the one in order to save space, and secondly, the replacement is also convenient, Third, using a mains adapter, the voltage is relatively high, put inside the machine is dangerous.

Role charger

In general, the role of the power adapter is a transformer and rectifier. Household AC voltage is 220V, and the charging voltage balance the car we needed much lower than the domestic power supply, it is possible to be sure the power adapter is a transformer and rectifier. Adapter is a transformer, then we should know, through a transformer 220V AC transformer through a rectifier to DC, where there is consumption, and consumption of these will be transformed into heat, so power adapter fever is normal. Is made ofsilicon steel transformer, the transformer after electricity, magnetic flux is generated, the magnetic flux will lead to action forces generated between silicon steel, resulting in a buzzing sound, this is normal. But too big sound is not normal, a lot of reasons: 1. AC voltage instability. 2. chip damage. 3. interturn short circuit. 4. component damage and so on. By the way, the role of the adapter is to convert alternating current into direct current electronic products.

How to control the balance car?

   Now, we have to sort out what the whole process for balance car. When we stand on the balance scooter, people and the car keep it upright, at the same time, acceleration sensors and gyroscopes main job is to make the balance wheel scooter still; when people focus forward, there is a significant body of forward tilt angle of the two sensors keen to capture this change, the current and speed control algorithm to control the motor, the motor began to gradually accelerate the rotation, the wheels rolling forward, so that you begin to accelerate. Deceleration process is similar.
 
In short, if you hope the smart self balancing scooter ride in a safe and stable situation, the two sensors in the non-stop measurements and calculations. Then the motor drive the wheels forward or backward. Of course, all this above, but also requires a lot of programs and algorithms to precisely control, in order to ensure safe driving car.
 
The forward principle for self balancing electric scooter
 
We know the car to go, of course, is two wheel rotation to achieve. The control wheel is a technology live. Wheels via two drive motors via a gear box, by controlling the motor speed can be achieved on the wheel motion control. Motion control is achieved by controlling the motor current to the motor coil to achieve. Controlling motor current, the control of the motor output torque (force).
Who control the balance car?
Who control the balance car?
But who controls the motor in it?
Simply put, when we stood finger stick when the stick forward and down, we came forward to offset the stick down trend. But you can not run too fast, otherwise it will stick back down. This time we are seeing the reverse angle and speed stick through the eyes to control their speed and direction of running.
 
Also the hoverboard scooter through the "eyes" to see the status of the car, so the Self Balancing Scooter and posture angular velocity measurements become the key to control. Measuring balance vehicle attitude and rate can be achieved by an acceleration sensor and a gyroscope. They are balanced by the car's "eyes.".

The simple Fault analysis and solution for hover board

Currently, the players in the purchase of electric hoverboard bluetooth or self balancing scooter encountered more trouble problem is motor failure, or balance system failure, usually accompanied by "drop" long ring. Most customers thought it was the motherboard, in fact, very often there is a cable connection is bad. Today tell customers automatically detects the exclusion of non-motor problems caused by the motherboard, balanced failure fault.
Hall cable connection is bad or off, or fitting inside one or more finger contacts bad, this will lead to failure. With the alarm sound "tick" sound, and the motor does not work. Usually can be connected directly or through re-plug the Hall line interface, or to resolve the row.

Wherein an electrical power line is bad or off, the motor power but can not walk, accompanied by great friction noise. Two lines off the motor or bad, completely off the motor does not work.

Common faults are the following:

1. The electric scooter wheel is out of balance, it will uncontrolled and when you stand up.
2. One wheel doesn’t work. Red light flash.
3. The sides of the wheel does not work. Red light flash.
Now we come to look at the self balancing electric scooter brushless motor, which has two sets of cables, respectively, a group of three different colors of the bold line is the power line, a set of five different colors of thread, is a Hall line.



A :( battery direction) motor power line it has three different colored lines, any one poor contact or disconnect , here the motor will lose balance, or time with abnormal sound. Poor contact or disconnect any two points, the motor will not work here. Tip lights do not flash.
B :( battery direction) line is composed of Hall 5 different color thread constitution. Any one line is bad or disconnected, resulting in both sides of the motors are not working. Tip lamp flashes 5 times each.
C: deputy board cable line is the set of four different colored lines, poor contact or disconnection, the motor will not work on both sides, running lights can work, cue lights flashed every time.
D and F: with light cable is bad or disconnected with lamp does not work.
E: Battery warning lamp is bad or the cable is disconnected, the battery light will prompt does not work.
G: deputy board cable line is the set of four different colored lines, poor contact or disconnection, the motor will not work on both sides, running lights can work, cue lights do not flash.
H :( switching direction) Hall line is composed of 5 different color thread constitution. Any one line is bad or disconnected, resulting in both sides of the motors are not working. Tip 4 under lights flash every time.
I :( switching direction) Motor power cable with three lines in different colors, any one bad or disconnected, the motor will be out of balance here, or driving when there is abnormal sound. Poor contact or disconnect any two points, the motor will not work here. The indicator light do not flash.
J: charging port is bad or the cable is disconnected, it will not charge.
K: switch cable is bad or off, switch button will fail.
L: Indicator lamp is bad or the cable is disconnected, the warning lamp does not work.
More cable problem, simply re-plug the cable or change can be solved.
Tally Explanations: flash one time: C partial failure flashes twice: No Flash 3 times: Motor short-circuit fault flash four times: H partial failure flash 5 times: B partial failure flashes 6 times: 7 times battery failure flash: Battery direction auxiliary circuit board failure, we need to replace the circuit board flash 8 times: switching direction auxiliary circuit board failure, you need to replace the circuit board.

Justin dance, very appealing, especially as Bieber Justin fans, such as myself. For more information about balance scooter, please visit http://www.koowheelmall.com

The Principle of the two wheel scooter

Two Wheel Electric Scooter is an electric, self-balancing ability of individuals to use transport vehicle, with an urban vehicle, it is an unprecedented new vehicle. Also known as the hover board, for personal transportation, patrol work, indoor stadium, golf cart, police patrol, patrol exhibition, large venues, staff transport, tourism and entertainment and car.
Mounted and many other aspects.
Even self balancing scooter price is expensive , but in China this super consuming countries, still has a good prospect.

Self Balancing Scooter was widely used in commercial and police field, played a very good effect. In China, self balancing scooter for sale is also very good, a lot of people are fascinated by its properties, and these included a lot of star groups.

It’s principle
The main operation principle of Self Balancing Electric Scooter is the self ability of balance car itself , which is the vehicle itself automatically balance (electronic self-balancing system EC). With built-in sophisticated electronic gyroscope (Solid-StateGyroscopes) to determine which body posture state, through
After precision and high-speed central microprocessor to calculate the appropriate instruction, the drive motor to achieve a balanced result. Suppose we stand in the overall center of gravity of the car and the driver of the vehicle longitudinal axis as the reference line. When the forward tilt of this axis, the balance within the body of the car will have built-in electric motor power forward, on the one hand the balance between man and Previous car dumped torque generated on the one hand to make the vehicle forward acceleration, on the contrary, when the gyroscope found the driver's center of gravity backward tilt, will produce a rearward force balance effect. Therefore, the driver simply changing the angle of his body forward or backward tilt, balance the car will tilt forward or backward based on the direction and the speed and extent of the driver's body is proportional to the tilt. In principle, as long as the balance of the car has the correct power is turned on and can maintain sufficient operating power, the people on board would not have to worry about the possibility of falling dumping, which is generally required by the driver of his own balancing scooter and other vehicles greatly different.
Features:
1, about two electric cars, a unique balance of design.
2, set the "Embedded Industrial Design + Art + Design" product integration of innovative technologies in order to enhance the inherent intelligent embedded technology products to meet the modern digital products, intelligent trend, from the inside out to achieve innovation.
3, product information modeling, the establishment of a product that contains both shape feature, also includes user awareness Imagery psychological characteristics system, and further development the user requirements for the final product-driven generation system. For more information, please visit http://www.koowheel.com.
