Description

Technical Field

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

[0002] Solenoid-controlled, adjustable damping shock absorbers are advanced automotive suspension system components that integrate modern electronics and hydraulic engineering. They are primarily used in high-end vehicles to enhance driving comfort and handling. Their core feature is the addition of a solenoid valve control module to a traditional shock absorber, enabling them to proactively and rapidly adjust damping force to accommodate changing road conditions and driving demands.

[0003] A search revealed a Chinese invention patent publication numbered CN214404474U, which discloses a solenoid valve-controlled damping adjustable shock absorber comprising an outer cylinder, an intermediate cylinder, a working cylinder, a piston-connecting rod assembly, a circulation valve system, and a solenoid valve assembly. The circulation valve system comprises a valve body, a circulation valve plate assembly, and an adjusting valve plate assembly. The valve body is provided with a first flange and a second flange, respectively. One end of the working cylinder is fitted on the first flange, and one end of the intermediate cylinder is fitted on the second flange. An annular groove is provided on the outer circumference of the first flange, and a sealing ring is provided in the groove. The solenoid valve assembly is provided on the side of the circulation valve system. The present invention optimizes the shock absorber structure and improves the circulation valve system structure to facilitate the manufacture, processing, and assembly of the solenoid valve-controlled shock absorber, effectively enhancing the sealing performance between the working cylinder and the circulation valve system, and improving the overall performance of the shock absorber.

[0004] However, the device often lacks the function of spring-assisted shock absorption. When in use, the spring and damper are combined to form an effective dual shock absorption system to jointly resist external impact. The solenoid valve-controlled damper alone may be difficult to fully cover the wide frequency band of vibration frequencies, especially in the case of high-frequency and small-amplitude vibrations. There is a lack of sufficient filtering effect, which reduces ride comfort. Not only that, the device also lacks the function of adapting to road conditions. When in use, different road conditions require shock-absorbing springs of different hardness to provide the best ride comfort and handling performance. For example, city streets require softer springs to filter small bumps, while off-road environments require hard springs to resist greater impacts. Fixed springs cannot meet diverse needs. Summary of the Invention

[0005] The object of the present invention is to provide a solenoid valve-controlled damping adjustable shock absorber to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A solenoid valve-controlled damping adjustable shock absorber includes a shock absorber, a fixing frame fixedly connected to the top of the shock absorber, a mounting groove is provided on the surface of the fixing frame, a mounting hole is provided on one side of the mounting groove, a shock-absorbing plate is clamped inside the mounting groove, a fixing hole is provided on the surface of the shock-absorbing plate, a connecting bolt is threadedly connected inside the fixing hole, a shock-absorbing spring is fixedly connected to the bottom of the shock-absorbing plate, a working cylinder is fixedly connected to the inside of the shock absorber, a piston rod is slidably connected to the inside of the working rod, the bottom of the piston rod is slidably connected to the shock-absorbing rod, and a self-restoring spring is fixedly connected to the surface of the shock-absorbing rod.

[0008] Preferably, a mounting frame is fixedly connected to one side of the shock absorber, and a solenoid valve is fixedly connected inside the mounting frame.

[0009] Preferably, the top of the working cylinder is fixedly connected to an upper cavity, and the bottom of the working cylinder is fixedly connected to a lower cavity.

[0010] Preferably, the bottom of the shock absorber is fixedly connected to a base, and the bottom of the base is fixedly connected to a bracket.

[0011] Preferably, a fixing groove is provided on the surface of the shock-absorbing rod, and a pressure sensor is fixedly connected inside the fixing groove.

[0012] Preferably, a placement groove is provided on the surface of the working cylinder, and a temperature sensor is fixedly connected inside the placement groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This solenoid valve-controlled damping adjustable shock absorber, when in use, is equipped with a shock absorber plate, a shock absorber spring, a piston rod, a shock absorber rod and a self-restoring spring. A fixing frame is installed on the top of the shock absorber, and the shock absorber plate is connected to the shock absorber through the fixing frame. When the shock absorber is subjected to impact energy, the shock absorber plate will absorb the impact and reduce vibration by deformation. The shock absorber spring is connected to the bottom of the shock absorber plate. When subjected to impact, the shock absorber spring will first contact the impact and use its own deformation to absorb and alleviate the initial vibration energy. The piston rod is connected to the inside of the shock absorber. When the vehicle is driving on the road, the vertical movement from the road will be directly converted into the up and down movement of the piston rod in the shock absorber. The shock absorber rod is connected to the bottom of the piston rod. The self-restoring spring connected to the surface of the shock absorber rod can push the piston rod upward to return to its original position after the piston rod is compressed downward by the impact, thereby achieving the effect of auxiliary shock absorption.

[0015] 2. This solenoid valve-controlled damping adjustable shock absorber, when in use, is connected to the top of the shock absorber through the arrangement of a fixing frame, a mounting groove, a mounting hole, a fixing hole and a connecting bolt. The shock absorbing plate can be connected to the surface of the fixing frame through the mounting groove opened on the surface of the fixing frame. A mounting hole is opened on one side of the mounting groove. After the mounting hole is connected with the fixing hole opened on the surface of the shock absorbing plate, the connecting bolt is inserted into the fixing hole for installation so that the shock absorbing plate can be fixed on the fixing frame. The shock absorbing spring wrapped around the outside of the shock absorber can be replaced through the mounting groove. By replacing the shock absorbing spring with different shock absorbing hardness, the shock absorber can adapt to different road environments, thereby achieving the effect of adapting to the road.
