Description

Technical Field

[0001] This utility model relates to the field of magnetorheological automotive shock absorber technology, and in particular to an improved magnetorheological automotive shock absorber. Background Technology

[0002] A vibration damper is a device used to reduce or suppress vibration, shock, or impact. It is commonly used in various mechanical systems and structures to reduce the impact of vibration on equipment and the environment. It can effectively reduce vibration and noise and improve system performance and reliability.

[0003] For example, the authorized announcement number "CN221278333U" is named a new type of magnetorheological automotive shock absorber. It provides magnetic force through built-in permanent magnets and electromagnets. When the piston rod is triggered, it can drive the permanent magnet to be exposed in the magnetorheological material, which can respond to the shock absorption demand more quickly.

[0004] The aforementioned and existing technologies have the following drawbacks: The damper's adjustment disc is prone to rotation under vibration, causing changes in the deformation of the return spring and creating a safety hazard. Furthermore, the return spring is exposed to air, making it susceptible to foreign objects and dust, which affects its lifespan. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an improved magnetorheological automotive shock absorber.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Preferably, the locking device includes two locking rods. Two through holes are symmetrically opened on the surface of the first mounting base. The locking rods pass through the through holes. The locking rods are threadedly connected to a first nut and a second nut. The first nut is located above the first mounting base, and the second nut is located below the first mounting base.

[0009] Preferably, the surface of the adjusting disk is provided with a plurality of locking slots arranged in a circumferential array, and the locking rod extends into the locking slots.

[0010] Preferably, the protective cover has multiple heat sinks arranged in a ring on its surface.

[0011] Preferably, each of the heat sinks has multiple heat dissipation holes on its surface.

[0012] Preferably, the inner walls of the multiple protective covers are provided with multiple protrusions, and the upper surface of the second mounting base is provided with positioning grooves corresponding to the multiple protrusions one by one. The protrusions extend into the positioning grooves, and the multiple protrusions are all fixed to the inner wall of the positioning grooves by bolts.

[0013] The improved magnetorheological automotive shock absorber proposed in this utility model has the following advantages: The damper's adjustment disc is less prone to rotation under vibration, preventing changes in the deformation of the return spring and avoiding potential safety hazards. The protective cover prevents the return spring from being exposed to air, and also blocks foreign objects and dust, extending the spring's service life. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4An improved magnetorheological automotive shock absorber includes a shock absorber body 1, a first mounting base 2 fixedly connected to the lower part of the shock absorber body 1, an adjusting disc 3 threadedly connected to the surface of the shock absorber body 1, and the deformation of the return spring 6 can be easily adjusted by rotating the adjusting disc 3; a locking device is provided between the first mounting base 2 and the adjusting disc 3; a piston rod 4 is slidably embedded on the upper surface of the shock absorber body 1, a second mounting base 5 is provided at the upper end of the piston rod 4, a return spring 6 is provided between the adjusting disc 3 and the second mounting base 5, and the return spring 6 is fitted on the shock absorber body 1 and the piston rod 4; a protective cover 7 is provided annularly on the surface of the first mounting base 2.

[0021] The locking device includes two locking rods 8. Two through holes 9 are symmetrically opened on the surface of the first mounting base 2. The locking rods 8 pass through the through holes 9. The locking rods 8 are threadedly connected to a first nut 10 and a second nut 11. The first nut 10 is located above the first mounting base 2, and the second nut 11 is located below the first mounting base 2.

[0022] The adjustable disk 3 has multiple locking slots 12 arranged in a circular array on its surface, and a locking rod 8 extends into the locking slot 12. The locking rod 8 extends into the locking slot 12 to prevent the adjustable disk 3 from rotating.

[0023] The protective cover 7 has multiple heat sinks 13 arranged in a ring on its surface. The heat sinks 13 serve to dissipate heat.

[0024] Multiple heat sinks 13 have multiple heat dissipation holes 14 on their surfaces. The multiple heat dissipation holes 14 serve to accelerate the heat dissipation of the heat sinks 13.

[0025] Multiple protective covers 7 have multiple protrusions 15 on their inner walls. The upper surface of the second mounting base 5 has positioning grooves 16 that correspond one-to-one with the multiple protrusions 15. The protrusions 15 extend into the positioning grooves 16, and all the protrusions 15 are threadedly connected to the inner wall of the positioning grooves 16 by bolts 17. By extending the protrusions 15 into the positioning grooves 16 and then fixing the protective covers 7 with bolts 17, the fixing method is easy to disassemble and easy to clean the protective covers 7.

[0026] Working Principle: The locking device in this automotive shock absorber, when the adjusting disc 3 is rotated to the appropriate position, secures it by passing the locking rod 8 through the through hole 9 and then fixing it with pliers. Tightening the first nut 10 brings the locking rod 8 against the adjusting disc 3, and then tightening the second nut 11 further secures it. In summary, the adjusting disc 3 of this automotive shock absorber is less likely to rotate under vibration, preventing changes in the deformation of the return spring 6 and avoiding safety hazards. The protective cover 7 prevents the return spring 6 from being exposed to air, blocking foreign objects and dust, and extending the service life of the return spring 6.
