What is a pull line toy car

Pull the string toy car, that is, there is a heel rope in the back, as soon as it is pulled out and then placed on the ground, it will go forward, as if it is wound. It's like a toy car with a thin line at the back, pull it out, and as soon as you let go, the toy car will run forward. In fact, it is a type of wind-up toy.

Benefits of Pull String Toys.

Pull line toys, the activity of the toy will attract the baby's attention, follow the visual ability of the toy's activity.

At first, you can hold the child in one hand and hold the child's little hand in the other, put the thread in his palm and pull the thread with him, so that he can experience the relationship between the string and the toy. After a few times, he will understand that only by pulling the string can he make the toy turn, and some of the pull toys will make sounds, and then he will be happy to play with the string himself.

For children, pulling the "animal" that can move will fascinate them, and they will gradually understand that this rope still has such a pulling force, which is more enlightening than those electric toy cars with dry batteries.

Security. Moreover, compared with electric toy cars, pull line toys are safe, if the child swallows 2 or more magnets, the suction in the body will lead to fatal damage to the intestines. Therefore, for children who like to put things in their mouths and bite, playing with easy release of magnets is more dangerous.

If the battery that your child swallows still has power, it can also cause burns in the body because it contains an electric current.

Hand activities are the basis for the next step in practicing grasping things, and when your baby's hands can open and hold things freely, you can give him some toys that are easy to hold to play. The full activity of the fingers is related to the development of the brain, and through the exercise of holding things, the coordination of the baby's hands and eyes can be promoted. If you give him a small toy, he will be able to hold it tightly.

The string toys can guide the baby to explore the chasing and dragging action, which not only improves his physical skills, but also exercises the baby's arm up and down pull, hand control ability and the development of small muscle groups of the hand, and develops problem-solving ability and cause and effect.

Generally, there is a thin line behind the car, pull it out, and as soon as you let go, the car will run forward.

In fact, it is a type of wind-up toy.

There is a thread behind the toy, pull it down, put it on the ground and it will run, hehe,

As soon as you pull the line of the safe, the principle is the same as that of the winding.

Runhong pull line car.

Pull it with a thread and it will move on its own.

The toy car motor belongs to the DC brush motor, I will post a small paragraph to show you, you can roughly understand it. If you want to grasp it carefully, it is recommended to buy a book to read.

The permanent magnet DC motor is also composed of stator poles, rotors, brushes, shells, etc., and the stator poles are made of permanent magnets (permanent magnets), with ferrite, alnico, neodymium iron boron and other materials. According to its structural form, it can be divided into cylindrical type and tile type. Most of the electricity used in VCRs is cylindrical magnets, while most of the motors used in power tools and automotive appliances use special block magnets.

Figure 18-12 is a schematic diagram of the magnetic circuits of the two permanent magnets.

The rotor is generally made of silicon steel sheets, which has fewer slots than the rotor of electromagnetic DC motors. Most of the low-power motors used in VCRs are 3-slot, and the higher-end ones are 5-slot or 7-slot. The enameled wire is wound between two slots of the rotor core (three slots have three windings), and each joint is welded to the metal sheet of the changer.

Brushes are conductive parts that connect the power supply to the rotor windings, and have both conductive and wear-resistant properties. The brushes of the permanent magnet motor use single metal sheets or metal graphite brushes, and electroized graphite brushes.

The function of the copper wire in the motor is to convert electrical energy into magnetic energy, and magnetic energy into mechanical energy.

Circuit masters use old copper wires, motors, voltages, etc., to create powerful tools.

After the copper wire passes through the current, it can generate magnetic force, and the permanent magnet fixed on the motor shell produces the driving force (or the pulling force of the engagement), and the commutator will switch to another set of coils to work after reaching a certain angle to continue the power.

You can find two magnets to make a motor model yourself!

You can sell scrap.
