Description

Technical Field

[0001] The invention relates to the technical field of damping shock absorbers, in particular to a self-powered adjustable damping shock absorber. Background Art

[0002] The damping shock absorber is a combination of a vibration-damping torsion spring and a rubber vibration-damping pad to get rid of its shortcomings. It has the advantages of composite vibration reduction and noise reduction, low resonance frequency, and good vibration reduction effect. It is better than protecting solid-transmitted sound, especially isolating high-frequency impact. It is an ideal product for passive vibration reduction. The damping shock absorber has a wide load coverage, a long service life, and reliable application. After searching, it is found that the damping shock absorber in the prior art is typically a damping shock absorber such as the publication number CN109595285A. The damping shock absorber includes an outer cylinder, an inner cylinder, a floating plug, a piston shaft, and a piston. The inner cylinder is arranged in the outer cylinder along the axial direction of the outer cylinder, the first end of the inner cylinder is sealed with the top end of the outer cylinder, and the second end extends to the bottom end of the outer cylinder; the side wall of the inner cylinder is provided with an air flow channel and a plurality of damping channels, each damping channel is located on one side of the air flow channel close to the bottom end and is spaced apart along the axial direction. The floating plug can be slidably sleeved outside the inner cylinder to form an oil cavity and an air cavity; the air flow channel connects the air cavity with the inner cylinder, and the damping channels connect the oil cavity with the inner cylinder. The piston shaft can slide through the top end and penetrate the inner tube. The first end of the inner tube is sealed with the top end of the outer tube, and the second end extends to the bottom end of the outer tube. The side wall of the inner tube is provided with an airflow channel and a plurality of damping channels, and is sealed with the top end. Its main feature is that the piston can slide and seal in the inner tube and is connected to the piston shaft. When the piston slides to the first position, the piston shields or exposes the airflow channel and exposes each damping channel. When the piston slides to the second position, the piston shields a part of each damping channel and exposes the airflow channel.

At the same time, the external energy supply is prone to accidental power outages due to damage to the external energy supply cable, resulting in the device being unable to work normally. In view of the above problems, it is necessary to improve the existing equipment. Summary of the invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: the self-powered adjustable damping shock absorber,

[0017] (1) The present invention can effectively solve the problem that the existing damping shock absorber needs external energy supply when in use, and cannot collect and utilize the kinetic energy generated by the vibration of the vehicle, which easily causes waste of resources. At the same time, the external energy supply is easily cut off due to damage to the external energy supply cable, resulting in the problem that the device cannot work normally. When the vehicle is bumpy, the suspension drives the shock absorber assembly to stretch and rebound together, so that within the expansion and contraction range of the shock absorber assembly, the miniature cylindrical linear reciprocating motion generator composed of the coil assembly and the permanent magnet assembly is pushed, that is, when the vehicle is bumpy, the permanent magnet assembly The components follow the telescopic movement of the shock absorber assembly and move up and down along the suspension inside the coil assembly to generate kinetic energy. At the same time, the kinetic energy is stored in the battery pack to provide power for related equipment inside the device, that is, to achieve the purpose of self-power supply and energy saving, and avoid the normal operation of the device being affected by damage to the external power supply wire. On the other hand, the permanent magnet assembly generates different voltages and currents according to the changes in the bumpy acceleration during the up and down movement. At the same time, the generated current control chip adjusts the damping regulating valve according to the control algorithm, that is, automatically adjusts the damping of the shock absorber assembly, thereby improving the flexibility of the device structure to meet different usage requirements;

[0018] (2) The present invention can effectively solve the problem that the existing damping shock absorber does not have the function of active heat dissipation, which is easy to cause overheating of the internal functional component, namely the battery pack, by using the first airbag ring and the permanent magnet assembly in combination. When the permanent magnet assembly moves downward with the suspension and the shock absorber assembly, it pushes the pad to squeeze the first airbag ring. After the first airbag ring is compressed, the internal gas enters the interior of the lower fixed plate through the conveying pipe and is sprayed toward the battery pack through the first nozzle at the bottom of the lower fixed plate, that is, the airflow sprayed by the first nozzle is used to assist in the heat dissipation of the battery pack. Similarly, when the permanent magnet assembly rebounds and moves upward, the first airbag ring is stretched, so that the external airflow enters the interior of the first airbag ring through the one-way air intake valve, that is, the airflow is supplemented for the first airbag ring to prepare for the next jet heat dissipation operation, thereby ensuring that the device continuously performs the cyclic heat dissipation operation;

[0019] (3) The present invention can effectively solve the problem of the coil assembly being contaminated by dust, which is prone to short circuit and overheating failure, by using the second airbag ring and the permanent magnet assembly in combination. When the permanent magnet assembly follows the suspension and shock absorber assembly to stretch the first airbag ring upward, it pushes the pad to squeeze the second airbag ring. After the second airbag ring is compressed, the internal gas enters the interior of the lower air storage ring and is sprayed toward the coil assembly through the second nozzle on the side of the lower air storage ring. That is, the airflow sprayed by the first nozzle is used to assist in heat dissipation and dust removal of the coil assembly. Similarly, when the permanent magnet assembly moves downward to squeeze the first airbag ring, the external airflow enters the interior of the second airbag ring through the one-way air intake valve, preparing for the next jet heat dissipation operation, thereby ensuring the normal operation of the coil assembly.

[0033] Specifically, in the actual working process, the mounting end 4 and the mounting ring 10 are first installed at corresponding positions of the vehicle. When the vehicle is bumpy, the suspension 3 drives the shock absorber assembly 8 to expand and contract and rebound together, so that within the expansion and contraction range of the shock absorber assembly 8, the miniature cylindrical linear reciprocating motion generator composed of the coil assembly 1 and the permanent magnet assembly 2 is pushed, that is, when the vehicle is bumpy, the permanent magnet assembly 2 follows the expansion and contraction movement of the shock absorber assembly 8 and moves up and down along the suspension 3 on the inner side of the coil assembly 1 to generate kinetic energy. At the same time, the kinetic energy is stored in the battery pack 7 to provide power for related equipment inside the device, that is, to achieve the purpose of self-power supply.
