[0005] An information processing mechanism, wherein the information transmitting end thereof is connected to the information receiving element in the transmission mechanism, and the information receiving element in the information processing mechanism is connected to the electric switch and brake of the automobile;

[0006] The information processing mechanism is used to receive information that the user releases the accelerator or steps on the brake, and transmits it to the transmission mechanism. The transmission mechanism assists in braking the wheels and transmits the kinetic energy generated when the wheels are braked to the information processing mechanism for storage.

[0007] Furthermore, the transmission mechanism includes: a transmission gear, one end of which is meshed with a brake gear provided on a wheel brake disc, and the other end of which is provided with a first transmission shaft, a second transmission shaft is provided at one end of the first transmission shaft away from the transmission gear, and a generator is connected to one end of the second transmission shaft away from the first transmission shaft; an electronic controller is provided between the first transmission shaft and the second transmission shaft; the electronic controller serves as an information receiving component of the transmission mechanism and can receive information sent by an information processing mechanism. Figure 5 The second transmission shaft part exists in the generator and is connected to the inside of the generator through gears. The gear length is long enough to allow the second transmission shaft to extend outward and connect with the first transmission shaft when meshing is required. When the connection is not required, the electronic controller can push the second transmission shaft back, thereby ensuring that the power output of the original vehicle will not be lost due to the device.

[0008] Furthermore, the information processing mechanism includes a signal source, which serves as an information receiving component of the information processing mechanism and can adopt a sensor-like device, which is connected to the car accelerator and brake to sense the user releasing the car accelerator or stepping on the brake.

The signal processing center controls the electronic controller to drive the second transmission shaft to move toward the first transmission shaft, so that the second transmission shaft is connected to the first transmission shaft. At this time, the second transmission shaft will give the brake gear a resistance to drive the transmission gear to rotate, thereby assisting the brake disc to brake;

[0017] S2: During braking, the brake gear drives the first transmission shaft and the second transmission shaft to rotate. The second transmission shaft transmits the rotational force to the generator. The generator converts kinetic energy into electrical energy and stores it in the capacitor storage device. When the vehicle needs power, the output motor transmits the kinetic energy to the output power drive wheel connected to it. The drive wheel generates power to achieve kinetic energy recovery.

Under normal circumstances, the two will not overlap or connect, and the two will not interact with each other, protecting the normal movement of the vehicle and the safety of parts. Only when braking, the two will interact with each other, the gear drives the transmission shaft to rotate to generate energy and connect to the generator, injecting the energy into the capacitor, and it will automatically disconnect after braking, ensuring the normal operation of the vehicle's own parts.
