Due to the constraints of battery technology and cost, new energy vehicles currently have range anxiety during use.

[0003] Most new energy vehicles can charge their batteries through kinetic energy recovery during driving. However, during driving, the vehicle body will also move up and down relative to the tires due to the ups and downs of the road or deceleration and braking. This process is mainly controlled by the vehicle's damper, that is, the shock absorber. The work done in the process of the damper's up and down extension can be used to generate electricity to charge the vehicle's power battery or directly transmit it to the motor. However, the damper power generation devices on the market are currently mainly concentrated inside the damper. In this case, the power generation is small, and the impact on the increase in the endurance of new energy vehicles is minimal. Summary of the invention

[0021] Figure 3 It is an overall schematic diagram of a damper power generation device installed in a car. DETAILED DESCRIPTION

[0022] In order to better understand the purpose, structure and function of the utility model, the following Figures 1 to 3 , a vehicle damper power generation device of the utility model is further described in detail.

[0023] like Figure 1 As shown, the automobile damper power generation device of the embodiment of the utility model is provided with at least one set of air compression device and one set of automobile damper device, wherein one set of air compression device includes a cylinder piston rod 2 and a compression cylinder body 1. The automobile damper device includes an automobile damper 19, a damper spring base 17, a coil spring 15, a damper support rod 18, a spring upper seat 16 and a piston in the damper body.

[0024] One end of the cylinder piston rod 2 is hingedly connected to the damper spring base 17 in the automobile damper device, and the other end is arranged in the compression cylinder body 1 of the air compression device. The first air delivery pipe 4 is arranged at the end of the compression cylinder body 1 away from the cylinder piston rod 2, and the interior of the compression cylinder body 1 is connected to the first air delivery pipe 4. One end of the automobile damper 19 is fixedly connected to the automobile tire component, and the other end is internally provided with a damper body inner piston, and the damper body inner piston is fixedly connected to one end of the damper support rod 18. A damper spring base 17 is also arranged on the side of the automobile damper 19 away from the damper support rod 18. The edge of the damper spring base 17 is hingedly connected to the cylinder piston rod 2. A coil spring 15 is arranged in the middle of the damper spring base 17. The damper support rod 18 is arranged inside the coil spring 15. The other end of the coil spring 15 is provided with a spring upper seat 16, and the side of the spring upper seat 16 opposite to the coil spring 15 is fixed to the automobile body.

[0025] When the car is driving, due to the ups and downs of the road or deceleration and braking, a number of automobile damper devices are arranged between the wheels and the car body, and the coil spring 15 inside the automobile damper device will perform telescopic movement. At this time, the automobile damper device drives the cylinder piston rod 2 to perform reciprocating movement in the compression cylinder body 1. Since the compression cylinder body 1 is provided with a cylinder one-way air intake valve 3, when the cylinder piston rod 2 is away from the bottom of the compression cylinder body 1, the air pressure inside the compression cylinder body 1 is less than the air pressure outside the cylinder, so the air will enter the compression cylinder body 1 from the one-way air intake valve 3. When the cylinder piston rod 2 moves toward the bottom of the compression cylinder body 1, the air inside the compression cylinder body 1 will be compressed and discharged through the first air delivery pipe 4.

[0026] The compressed air enters the first air delivery pipe 4 from the compression cylinder body 1, and will reach the air storage tank intake valve 5 along the first air delivery pipe 4. The valve is a one-way valve. The compressed air can only enter the air storage tank 6 through the air storage tank intake valve 5, and cannot enter the first air delivery pipe 4 from the air storage tank 6 through the air storage tank intake valve 5. As the compressed air in the air storage tank 6 increases, the pressure increases. When the threshold is reached, the air storage tank exhaust valve 8 will open to exhaust and release the compressed air in the air storage tank 6. The compressed air is transported to the generator 9 through the second air delivery pipe 41 to drive the generator 9 to generate electricity. Since the compressed air entering the generator at one time is temporarily stored in the air storage tank 6 and then released uniformly, it can drive a generator with a larger power generation capacity than directly driving the generator to generate electricity from the compressed air in the compressed cylinder body 1. At the same time, less air is lost in the air delivery pipeline. As a result, when the same automobile damper device performs the same amplitude and amount of telescopic movement, the compressed air released after being temporarily stored in the air storage tank 6 will generate more electricity and be more efficient.

[0027] In order to improve the quality of air entering the compression cylinder body 1 and reduce the entry of impurities in the air, an air intake filter 31 is arranged at the intake end of the cylinder one-way intake valve 3. This device can improve the quality of air entering the compression cylinder body 1, extend the service life of the entire device, and reduce the frequency of failures.

[0028] An air pressure gauge 7 can also be set on the air storage tank 6. On the one hand, it can monitor the pressure in the air storage tank 6 to avoid malfunctions caused by excessive pressure; on the other hand, the air storage tank exhaust valve 8 uses an electromagnetic valve. When the air pressure gauge 7 monitors that the air pressure in the air storage tank 6 reaches a threshold, the air storage tank exhaust valve 8 is opened through a control device to release compressed air.

[0029] The generator 9 uses an air turbine magnetic levitation generator. Compressed air generates electricity by driving a turbine blade 10. This generator uses magnetic levitation technology. The rotor in the generator is suspended in the air, and there is no rotation of traditional mechanical bearings. Therefore, the air turbine magnetic levitation generator eliminates the friction and wear of the mechanical bearings, thereby improving the efficiency and life of the generator. The generator 9 is also provided with a generator inverter 11, which can adjust the speed and protect the motor, so that the motor can operate more efficiently, safely and stably during work.

[0030] After the compressed air passes through the generator 9 and is used for power generation, it is discharged into the air hot and cold vortex separator 12 through the third air delivery pipe 42. The vortex tube causes the airflow entering the air hot and cold vortex separator 12 to generate a vortex, thereby separating the cold and hot airflows, wherein the hot air is discharged through the hot end exhaust port 14 and the cold air is discharged through the cold end exhaust port 13. The separated cold or hot air can be input into the car again and used for heat dissipation of the car motor as needed, and for maintaining the appropriate temperature of the battery and / or the interior of the car.

[0031] like Figure 2 As shown, three sets of air compression devices are arranged on a set of automobile damper devices and are arranged in a circular array around the automobile damper 19. The cylinder piston rod 2 of each set of air compression devices is hingedly connected to the damper spring base 17, and the compression cylinder body 1 of each set of air compression devices is connected to the first air delivery pipe 4. When in use, the three sets of air compression devices will operate simultaneously and compress the air together and input it into the first air delivery pipe 4, thereby improving the efficiency of power generation.

[0032] like Figure 3 As shown, each car is equipped with several car dampers, and each damper is provided with several air compression devices. The air compressed by these air compression devices is collected into the same air storage tank 6 through the first air delivery pipe 4 for temporary storage, and after the compressed air in the air storage tank 6 is released, it is delivered to the same generator 9 through the second air delivery pipe 41 for power generation. Compared with setting multiple air storage tanks 6 and motors 9, such a design can reduce the loss in the pipeline, increase the air capacity in the air storage tank 6, and deliver more air to the generator 9 at the same time, and the power generation efficiency is also higher; at the same time, it reduces the space occupied by the entire car damper power generation device in the car.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of protection of the present invention.
