How to choose an electric baby car How to choose a children's electric car

Children's carriage products mainly include children's bicycles, children's tricycles, children's strollers, baby walkers, and electric baby carriages, which are indispensable supplies in the process of children's growth.

When purchasing a stroller, you should pay attention to the following issues:

Attention should be paid to whether there are sharp points, sharp edges and protrusions on the surface of baby carriage products that children's hands and legs may touch, which may cause injury accidents to children.

Attention should be paid to whether the various coatings on the surface of baby carriage products have obvious peeling phenomenon.

Selection of different types of strollers

1. Children's bicycle

Does the bicycle chain cover cover the outer surface and edge of the chain, sprocket, flywheel, and the inner surface of the meshing part of the chain and sprocket? If these parts are not covered, children's fingers can reach in and touch them, and children may be injured finger injury.

Whether the size of the brake handle of the bicycle is suitable for your child, if it is not suitable, the child may not be able to hold the brake handle tightly, and the bicycle cannot be braked when riding, which is prone to accidents.

Whether the grip and the cross tube are tightly combined (the standard requires that it can withstand a pull-off force of 70N), generally you can twist the grip to feel whether there is relative rotation between the grip and the cross tube. If the combination is not tight, when children ride bicycles, it will be difficult to handle because of the slippage of the handlebars, and accidents will easily occur.

2. Baby walker

Whether the various small toys installed on the baby walker are firmly installed, if they are easily torn off by children, they will cause injuries due to children eating by mistake while playing.

The overall rigidity of the baby walker, whether the crotch belt is firm, and whether the locking device is effective, can at least bear the weight of the child without obvious deformation and damage.

The stability of the baby walker is a very important safety indicator for the baby walker. If the stability is not good, when the baby moves quickly in the baby walker, once it hits an object (such as steps, threshold) , it is easy to fall over and cause serious injury. Generally speaking, if the appearance and function are satisfied, try to choose a baby walker with a smaller upper frame and a larger bottom frame.

3. Children's stroller

Whether the brake device of the cart is effective.

Whether the locking device and safety belt device of the stroller are firm and reliable, and its structure can prevent children from falling out of the vehicle.

4. Children's tricycle

Pay attention to the stability of the tricycle. The child sits on the saddle of the tricycle and lifts the front and rear wheels by about 10 cm to see if the vehicle will tip over forward or backward.

For tricycles, it is also necessary to pay attention to whether the handlebar and the horizontal tube are tightly combined.

5. Electric stroller

The various switches of the electric stroller should be able to control the corresponding functions with clear instructions.

The transmission mechanism of the electric stroller should be closed to avoid pinching children's fingers.

The speed of the electric stroller should not be too fast (at the rated load, the speed should not exceed 70mm/min), so as to avoid accidents when children are riding.

4. Read the instructions carefully before purchasing and using various types of baby carriages, because different baby carriages have different rated loads, applicable age ranges, assembly requirements, maintenance methods, etc. , causing harm to children.

Children's electric vehicle fault repair

1. If the electric vehicle is completely out of power. how to deal with

1. First check whether the battery has an output and whether the wire is open for welding.

2. Then check whether the fuse and the fuse seat are good or bad.

3. Finally, check whether the power lock is good or bad.

2. The car does not go when it has electricity. how to deal with

1. Check whether the battery output of the electric vehicle is normal. If the output is too low, it proves that the battery is bad, and the battery should be replaced.

2. Pull out the brake line. If the car rotates, it proves that the handle is broken and needs to be replaced or repaired. It is possible to use Table 2 and measure the handle. <Ordinary long-close handle.

3. Check the handlebars. Short-circuit the positive and signal lines of the handlebars with iron wires. If the car turns, it proves that the handlebars are broken and need to be replaced or repaired urgently. Turn on the power and turn the handle. Use a multimeter to measure the positive line and signal line with positive 5V <1-4> turn the handle.

4. Whether the controller is good or not, you can use the positive 5V of the turning handle to short-circuit it. If the turning handle turns, it means that the controller is fine. The easiest way is to smell whether the controller has a burnt smell. If so, it proves that the controller is bad.

5. Check whether the motor is good or not. Incorrect contact of the carbon brush of the motor will also cause a little sticking.

3. How to repair the motor of children's electric vehicle <Brush and brushless>

1. If the brush motor is connected with a multimeter, it proves that the motor is good or not.

2. The eight wires of the brushless motor are black, red, yellow, green, blue, big yellow, big green, big blue. The black wire of the motor with the red pen of the meter can be used to prevent the motor from 650-750. no problem.

3. The brushed motor of an electric vehicle generally replaces the carbon brush. Before opening, pay attention to whether the friction between the alternator and the carbon brush is not connected. If so, use sandpaper to rub the alternator and the carbon brush to keep the same distance.

4. Turn on the motor and be careful not to rub the wire pack of the motor to avoid damage to the wire pack. Do not stick the magnet with iron to avoid cracking the magnet.

5. When replacing the Hall of the brushless motor, pay attention to the connection of the Hall wires. If it is the first time, it is best to remove the wires and weld them together to avoid welding errors. In order to avoid the phenomenon of infirmity.

6. Change the magnetic steel, dip the magnetic steel, pay attention to make the glue on the spindle and the magnetic steel clear and clean, and use the magnetic steel and the magnetic steel to attract each other, put the glue in the opposite direction and then stick it.

4. Turn on the power of the electric door lock, and the power indicator light on the instrument panel does not light up. Turn the handle, the motor does not turn.

1. The fuse on the battery box is burnt out: replace the fuse.

2. Poor contact of the fuse on the battery box: adjust the fuse tube to make it in good contact.

3. Poor contact of the contacts on the battery box: adjust the contacts to make good contact.

4. The contacts of the battery box are burnt out: replace with new contacts.

5. The electric door lock is burnt out: replace with a new electric door lock.

6. The battery leads in the battery box are disconnected: update the connection line.

7. The internal circuit of the battery in the battery box is broken: replace or repair the battery.

8. Open circuit or poor contact of electric door lock lead wire or contact lead wire: re-wire.
