A toy for children to play in which the basic structure and appearance of the car are reduced in a certain proportion.
The structure of toy cars includes inertia type, mechanical type, electric type and electric remote control type.
Toy cars are made of plastic, metal, etc.
Compared with the simulation car model, the toy car is flexible in size design, slightly rough in technology, and simple in material. Generally made of ordinary plastic, iron sheet. Toy designers do not need authorization and technical support from the original car factory
Pull back car The “shaft” connected to the rear tire of the pull back car is fixedly connected with the gears in the pull back gear. When the hand is working backwards on the car, the rear wheels rotate backward, and the shaft transmits power to the pull back gear to do work. The gear drives the pull back gear. The structure (spring structure or rubber band structure) converts the kinetic energy made by the hand into potential energy (for example, the rubber band rotates and stretches or the spring compresses, etc.). When the hand is released, the car loses a force to maintain its balance, that is, by the increased friction between the rear tire and the ground when the car is pressed by hand (that is, the grip force commonly referred to in F1), the return gear will The potential energy is released through the shaft to do work in the opposite direction, so the shaft turns the potential energy into a function by rotating. Because the pull back car is usually designed to drive the rear wheels forward (that is, the wheels are seen counterclockwise when viewed from the left side of the car), the pull back gear is designed to store energy back (that is, the wheels are clockwise when viewed from the left side) Therefore, as long as the back gear can accumulate enough (ie, the number of revolutions is enough) or the static friction between the back gear is small enough, the back car can move forward through the heart’s energy output.
Friction car The simplest understanding is a car that relies on inertia. One of the biggest differences between inertia cars and pull back cars is that they can be exercised before and after. The mechanical principle of the inertia car is mainly concentrated in a device called a “flywheel”. When the rear wheel is pulled backward (or pushed forward), it drives the flywheel to rotate quickly in the reverse direction and pulls back like a spring, and it stores many rotations. Kinetic energy, when you let go, its energy is released, which drives the car’s rear wheel to rotate forward (backward) so that the cart can rush forward (backward) for a long distance. It turns out that energy is like a rubber band. Pull back to store energy, and release it when you let go.
RC toy car A toy remote control car is a model car that can be remotely controlled by a radio remote control. According to the body shape, it can be divided into: ordinary private car, off-road vehicle, container truck, dump truck and so on. For example, off-road vehicles in real life can not only adapt to various road conditions in the wild, but also give people a rough and bold driving superiority. However, as an ordinary child or an ordinary game player, it is possible to achieve a “driving pleasure” to a certain extent by operating an ordinary remote-controlled toy car. Of course, this feeling is far from being comparable to driving a real car. The remote control car has many control actions. Check the control sensitivity one by one when selecting. Pay special attention to the antenna of the transmitter to the longest when starting the inspection. After everything is normal, shorten the antenna slowly and observe the shortening of the control distance. Generally, when the antenna is reduced to half its full length, and the control distance is shortened by one third, it is normal. For children under 6 years old, just choose a single channel remote control toy. Its actions are relatively simple. The launcher also has only one button, which can only control the toy to change one action, such as changing from forward to backward. For children over 6 years of age, you can choose multi-channel remote control toys to allow children to master more complex manipulation skills.
