Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to an automobile shock absorber with adjustable damping function. Background Art

[0002] Automobile shock absorbers are an important part of the automobile suspension system. Their main function is to suppress the shock caused by the rebound of the spring after absorbing shock and the impact from the road, thereby improving the driving smoothness and ride comfort of the car. Through the damping effect, the shock absorber converts the elastic potential energy generated by the uneven road surface when the vehicle is driving into heat energy, dissipates it into the atmosphere, and reduces the violent shaking of the car body.

[0003] Traditional automobile shock absorbers adjust different shock-absorbing damping forces by manually adjusting the length of the coil spring compression or extension. However, manual operation is cumbersome, time-consuming, and labor-intensive, which reduces the convenience of use. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an automobile shock absorber with adjustable damping function.

[0005] The utility model is implemented by the following technical solution: an automobile shock absorber with adjustable damping function, comprising a damper, a coil spring sleeved on the surface of the damper, an upper limit plate provided on the upper end of the damper, an adjustment assembly provided on the lower end of the coil spring, and a protective box fixedly connected to the bottom of the damper;

[0007] Through the above technical solution, the worm is driven by the motor to rotate, so that the worm wheel rotates, which drives the lead screw to rotate, so that the connecting seat slides upward along the damper, so that the lower limit plate moves upward and the coil spring is compressed. When the lower limit plate moves downward, the coil spring will stretch, so that the deformation degree of the coil spring is different, thereby bringing different shock-absorbing damping forces. No manual operation is required, which improves convenience during use.

[0008] As a further improvement of the above solution, the inner wall of the lower limit plate is slidingly connected to the surface of the damper, the top of the lower limit plate contacts the bottom of the coil spring, and the number of the fixing rods is four, and the four fixing rods are distributed in a circle around the lower limit plate.

[0009] Through the above technical solution, the direct connection stability between the lower limit plate and the connecting seat is ensured by four fixing rods.

[0010] As a further improvement of the above solution, the inner wall of the connecting seat is slidingly connected to the surface of the damper, one end of the fixing seat is fixedly connected to the surface of the damper, and the lower end of the screw rod passes through the protective box and extends to the interior of the protective box.

[0011] Through the above technical solution, the connecting seat is slidably connected to the surface of the damper, so that the connecting seat slides up and down along the surface of the damper when moving, ensuring the stability of the connecting seat when moving.

[0012] As a further improvement of the above solution, one end of the worm away from the motor is rotatably connected to the inner wall of the protection box, and one end of the motor is fixedly connected to the inner wall of the protection box.

[0013] Through the above technical solution, the worm gear self-locking function is used to prevent the screw from rotating in the non-adjustment state, ensuring that the position of the lower limit plate will not change. The internal components are protected by the protective box to reduce damage.

[0014] As a further improvement of the above solution, the bottom of the protective box is fixedly connected to a lower connecting seat, the upper end of the damper is fixedly connected to a limiting ring, the surface of the limiting ring contacts the inner wall of the upper limit plate, and the bottom of the upper limit plate contacts the top of the coil spring.

[0015] Through the above technical solution, the position of the upper limit plate is limited by the limiting ring, and the top of the coil spring is limited by the upper limit plate.

[0016] As a further improvement of the above solution, the top of the damper is fixedly connected to an extension rod, the surface of the extension rod is threadedly connected to a fixing plate, and the top of the fixing plate is fixedly connected to an upper connecting seat.

[0017] Through the above technical solution, the fixing plate is connected to the surface of the extension rod through threads, which facilitates the subsequent disassembly of the fixing plate.

[0018] As a further improvement of the above solution, the inner wall of the fixed plate is threadedly connected to a threaded rod, which passes through the fixed plate and is threadedly connected to the inner wall of the upper limit plate. The lower surface of the fixed plate contacts the upper surface of the upper limit plate.

[0019] Through the above technical solution, a plurality of threaded rods are passed through the fixing plate and the inner wall of the upper limit plate for threaded connection, thereby installing and fixing the upper limit plate, which is convenient for subsequent disassembly.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model sets an adjustment component, specifically, a motor drives the worm to rotate, so that the worm wheel rotates, drives the lead screw to rotate, and causes the connecting seat to slide upward along the damper, so that the lower limit plate moves upward and the coil spring is compressed. When the lower limit plate moves downward, the coil spring will stretch, so that the deformation degree of the coil spring is different, thereby bringing different shock-absorbing damping forces, and no manual adjustment is required, which improves the convenience and adjustment efficiency during use, and can achieve precise adjustment of the damping force to meet different road conditions and driving requirements.
