Description

A shock absorber with a vibration damping system protection device Technical Field

[0001] This utility model relates to the field of shock absorber protection technology, and more specifically, to a shock absorber with a vibration damping system protection device. Background Technology

[0002] Shock absorbers are mainly used to suppress the rebound oscillations generated by the spring after absorbing the impact, and to effectively buffer the impact from the road surface, thereby improving the ride smoothness and handling of the vehicle.

[0003] Currently, commonly used shock absorbers may experience excessive compression due to large impact forces during actual use, thus shortening their service life. For example, the shock absorber with vibration damping system protection device disclosed in publication number CN204358006U has a hub limiting seat installed on the hub, a hub side limiting post fixedly installed on the hub limiting seat, and a hub side anti-detachment platform at the top of the hub side limiting post. A hub side plastic elastic limiting device is tightly plastically molded outside the hub side limiting post and the hub side anti-detachment platform. A driven plate limiting seat is installed on the damping plate and the driven plate, and a driven plate side limiting post is fixedly installed on the driven plate limiting seat.

[0004] As can be seen from the above-mentioned publicly available solution, when one end of the shock absorber is subjected to impact and compression, the shock absorber spring will contract to buffer the impact. However, when the impact force is large, the shock absorber spring may break due to excessive compression, which shortens the service life of the shock absorber. At the same time, the elasticity of the shock absorber spring cannot be adjusted, which brings certain inconvenience to the use. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a shock absorber with a vibration damping system protection device. This shock absorber, through the setting of an abutment plate and a compression plate, prevents one end of the shock absorber piston rod from impacting the interior of the shock absorber body when compressed. It also limits the compression position of the shock absorber spring, protecting the shock absorber and extending its service life. Furthermore, the setting of a fixed seat and support column not only supports and limits the abutment plate and adjustment seat but also allows for adjustment of the height of the adjustment seat, thereby adjusting the elastic strength of the shock absorber spring.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A shock absorber with a vibration damping system protection device includes a shock absorber body. A piston rod is slidably connected to one end of the shock absorber body. A damping spring is movably sleeved on the outer side of the shock absorber body and the piston rod. A compression plate is fixedly connected to one end of the piston rod. An upper connecting lug is fixedly connected to the top of the compression plate. A fixed seat is fixedly connected to the other end of the shock absorber body. A mounting groove is opened at the center of the fixed seat. A lower connecting lug is fixedly connected to the bottom of the fixed seat. A protective mechanism is detachably connected to the surface of the fixed seat. This shock absorber with a vibration damping system protection device, through the setting of the abutment plate and the compression plate, prevents one end of the shock absorber piston rod from impacting the interior of the shock absorber body when it is compressed. At the same time, it can also limit the compression position of the damping spring, protect the shock absorber, and extend the service life of the shock absorber. Furthermore, through the setting of the fixed seat and the support column, not only can the abutment plate and the adjustment seat be supported and limited, but the height position of the adjustment seat can also be adjusted, thereby adjusting the elastic strength of the damping spring.

[0008] Furthermore, the protective mechanism includes a support column, one end of which is threadedly connected to an abutment plate, an adjusting seat is slidably connected to the surface of the support column, and a support nut is threadedly connected to the surface of the support column. The end face of the support nut is movably connected to the bottom of the adjusting seat, and the support nut can be adjusted up and down on the surface of the support column to adjust the support height of the adjusting seat.

[0009] Furthermore, the surface of the support column is fixedly fitted with axially symmetrical fixing nuts, the surface of the support column is threaded with external threads, the surface of the fixing seat is threaded with a lower connecting hole, the bottom of the abutment plate is threaded with an upper connecting hole, and the inner walls of the lower connecting hole and the upper connecting hole are threaded with opposite internal threads, so as to facilitate the simultaneous assembly and disassembly of the fixing seat and the abutment plate at both ends of the support column.

[0010] Furthermore, the surface of the adjusting seat has an adjusting hole, and a bushing is fixedly fitted in the middle of the adjusting seat. The bushing has a central hole in the middle, and the inner wall of the central hole is slidably connected to the surface of the shock absorber body. The bushing can prevent the adjusting seat from causing wear on the surface of the shock absorber body.

[0011] Furthermore, a limiting sleeve is fixedly connected to the surface of the adjusting seat, and an anti-disengagement groove is formed between the limiting sleeve and the bushing. The inner wall of the anti-disengagement groove is movably connected to one end of the shock-absorbing spring, and the anti-disengagement groove can limit the lower end of the shock-absorbing spring.

[0012] Furthermore, a clearance hole is provided in the middle of the contact plate, and a buffer pad is fixedly connected to the top of the contact plate. The buffer pad is made of buffer rubber, which can prevent the contact plate from being damaged when it comes into contact with the extrusion plate.

[0013] Furthermore, the bottom of the extrusion plate has an annular groove, and the size of the annular groove is the same as the size of the anti-detachment groove. The annular groove can limit the upper end of the shock-absorbing spring.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] This design, through the use of abutment plates and compression plates, prevents the piston rod of the shock absorber from impacting the interior of the shock absorber body when it is compressed. It also limits the compression position of the shock absorber spring, thus protecting the shock absorber and extending its service life.

[0016] This solution, through the setting of fixed seats and support columns, can not only support and limit the contact plate and adjustment seat, but also adjust the height of the adjustment seat, thereby adjusting the elastic strength of the shock-absorbing spring. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Embodiment 1

[0025] Please refer to Figures 1-5. A shock absorber with a vibration damping system protection device includes a shock absorber body 1. A piston rod 11 is slidably connected to one end of the shock absorber body 1. The piston rod 11 has a telescopic function, allowing the shock absorber body 1 to buffer impact forces. The structure and working principle of the piston rod 11 and the shock absorber body 1 are prior art. A shock-absorbing spring 12 is movably sleeved on the outer side of the shock absorber body 1 and the piston rod 11. The shock-absorbing spring 12 has a buffering and shock-absorbing function when compressed by the compression plate 13. One end of the piston rod 11 is fixedly connected to the compression plate 13. The top of the compression plate 13 is fixedly connected to an upper connecting lug 14. The other end of the shock absorber body 1 is fixedly connected to a fixing seat 5. A mounting groove 51 is opened at the center of the fixing seat 5. The mounting groove 51 can increase... The connection area between the fixed seat 5 and the shock absorber body 1 is increased to improve the connection firmness. The bottom of the fixed seat 5 is fixedly connected to the lower connecting ear 53. The surface of the fixed seat 5 is detachably connected to the protective mechanism 2, which includes a support column 6. One end of the support column 6 is threadedly connected to the abutment plate 4. The abutment plate 4 has a clearance hole 41 in the middle position. The top of the abutment plate 4 is fixedly connected to the buffer pad 42, which is made of buffer rubber to prevent the abutment plate 4 from being damaged when it comes into contact with the compression plate 13. The surface of the support column 6 is slidably connected to the adjusting seat 3. The surface of the support column 6 is threadedly connected to the supporting nut 62. The end face of the supporting nut 62 is movably connected to the bottom of the adjusting seat 3. The supporting nut 62 can be adjusted up and down on the surface of the support column 6 to adjust the support height of the adjusting seat 3.

[0026] Axially symmetrical fixing nuts 61 are fixedly sleeved on the surface of the support column 6. The surface of the support column 6 has external threads. The surface of the fixing seat 5 has a lower connecting hole 52. The bottom of the abutment plate 4 has an upper connecting hole 43. The inner walls of the lower connecting hole 52 and the upper connecting hole 43 have internal threads with opposite threads, which facilitates the simultaneous installation and removal of the fixing seats 5 and the abutment plate 4 at both ends of the support column 6. The surface of the adjusting seat 3 has an adjusting hole 33. A bushing 31 is fixedly sleeved in the middle position of the adjusting seat 3. A center hole 32 is provided in the middle of the bushing 31. The inner wall of the center hole 32 is slidably connected to the surface of the shock absorber body 1. The bushing 31 can prevent the adjusting seat 3 from causing wear on the surface of the shock absorber body 1.

[0027] A limiting sleeve 34 is fixedly connected to the surface of the adjusting seat 3. An anti-detachment groove 35 is formed between the limiting sleeve 34 and the bushing 31. The inner wall of the anti-detachment groove 35 is movably connected to one end of the shock-absorbing spring 12. The anti-detachment groove 35 can limit the lower end of the shock-absorbing spring 12. An annular groove is opened at the bottom of the extrusion plate 13, and the size of the annular groove is the same as the size of the anti-detachment groove 35. The annular groove can limit the upper end of the shock-absorbing spring 12.

[0028] When the shock absorber with vibration damping system protection device is in use, the compression plate 13 is subjected to downward compression force, which compresses the piston rod 11 and the shock-absorbing spring 12. The piston rod 11 and the shock-absorbing spring 12 move downward to buffer and dampen the impact force. When the compression plate 13 moves downward so that the lower end of the piston rod 11 is almost at the bottom, the bottom of the compression plate 13 contacts the top of the abutment plate 4, limiting the compression plate 13 from moving further downward. This prevents the lower end of the piston rod 11 from colliding with the inside of the shock absorber body 1, and also prevents the compression plate 13 from excessively compressing the shock-absorbing spring 12. When it is necessary to increase the elastic strength of the shock-absorbing spring 12, the nut 61 can be fixed by using a wrench to prevent the support column 6 from rotating. Then, another... Rotating the wrench counterclockwise on the support nut 62 causes it to move upward along the support column 6, which in turn moves the adjusting seat 3 upward to compress the shock absorber spring 12, thereby increasing the spring strength of the shock absorber spring 12. The contact plate 4 and the compression plate 13 prevent the piston rod 11 from impacting the inside of the shock absorber body 1 when it is compressed, and also limit the compression position of the shock absorber spring 12, protecting the shock absorber and extending its service life. Furthermore, the fixed seat 5 and the support column 6 not only support and limit the contact plate 4 and the adjusting seat 3, but also allow for adjustment of the height of the adjusting seat 3, thereby adjusting the spring strength of the shock absorber spring 12.

[0029] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
