Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts technology, specifically to a rubber shock absorber for automotive suspension. Background Technology
[0002] Many rubber components are used in car suspensions to improve the overall shock absorption effect. Among them, the buffer rubber used on car suspension shock absorbers is also a type of rubber component. When used, the buffer rubber is fitted onto the shock absorber telescopic rod. When the car is pressing down, the buffer rubber cushions the shock absorber, preventing the spring in the shock absorber from bottoming out instantly. It protects the shock absorber, improves the overall shock absorption effect, reduces noise, and compensates for the width margin left by the shock absorber.
[0003] Existing shock absorbers are simply rubber products with a cushioning structure. After being repeatedly compressed by the shock absorbers in the suspension, they are prone to cracking or losing their elasticity, thus failing to perform their functions of shock absorption, cushioning, and noise reduction. Since the shock absorber is installed under the vehicle, the driver may not easily notice any damage to it. If not detected in time, it can easily lead to damage to the suspension shock absorbers, resulting in greater economic losses. At the same time, both ends of the shock absorber lack protection and are easily crushed by the protrusions on the shock absorbers. Therefore, a new type of rubber shock absorber for automotive suspension is proposed. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a rubber shock absorber for automobile suspension to solve the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a rubber shock absorber for automobile suspension, comprising a buffer rubber, with end plates fixedly installed at both ends of the buffer rubber, a first connector fixedly connected to the outer wall of one end plate, and a second connector fixedly connected to the outer wall of the other end plate, an adjusting plate fixedly connected to one end of the outer wall of the first connector, a touch rod installed on the adjusting plate, and a touch switch cooperating with the touch rod installed on the end face of the second connector.
[0006] Preferably, a third connector is fixedly connected to the outer wall of one end plate, and a fourth connector is fixedly connected to the outer wall of the other end plate. A limit sleeve is installed on the end face of the third connector, and a slide rod that is slidably connected to the inner wall of the limit sleeve is installed on the end face of the fourth connector.
[0007] Preferably, the side wall of the third connector has a through hole, through which the slide rod moves.
[0008] Preferably, there are two of each of the first connector, the second connector, the third connector, and the fourth connector, and they are all symmetrically distributed.
[0009] Preferably, both ends of the buffer rubber are provided with mounting grooves, the end plate is installed in the mounting grooves, and both ends of the outer wall of the buffer rubber are provided with clearance grooves. The first connector, the second connector, the third connector and the fourth connector are all installed in the clearance grooves.
[0010] Preferably, both ends of the buffer rubber have relief openings on their inner walls, and the inner walls of the relief openings have limit openings. The side walls of the end plate are fixedly connected with sleeves, which are movably engaged in the relief openings and limit openings. The end plate is movably installed with the buffer rubber through the sleeves.
[0011] Preferably, a limiting groove is provided on the bottom surface of the adjusting plate, the contact rod is slidably connected in the limiting groove, two limiting blocks are fixedly connected to the outer wall of the contact rod and slidably connected to the inner wall of the limiting groove, and a bolt is rotatably connected to the upper end of the adjusting plate, the bolt being threadedly connected to the inner wall of the contact rod.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] This invention protects the ends of the buffer rubber by installing end plates at both ends. A touch switch and an adjustment plate are installed through the first and second connectors on the side walls of the end plates. When the buffer rubber is compressed, the two end plates will move closer together. When the buffer rubber breaks or its elasticity is repeatedly compressed to the point of insufficiency, the two end plates will move even closer due to the compression of the buffer rubber. This will cause the touch switch to contact the contact rod on the adjustment plate, thereby sending a damage signal to the driver and prompting timely replacement of the buffer rubber to avoid greater economic losses.
[0014] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures pointed out in the description, claims, and drawings. Attached Figure Description

Detailed Implementation
[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-6 This utility model discloses a rubber shock absorber for automotive suspension, comprising a buffer rubber 1, with end plates 2 fixedly installed at both ends of the buffer rubber 1. A first connecting member 3 is fixedly connected to the outer wall of one end plate 2, and a second connecting member 4 is fixedly connected to the outer wall of the other end plate 2. An adjusting plate 6 is fixedly connected to the outer wall of one end of the first connecting member 3, and a contact rod 7 is installed on the side wall of the adjusting plate 6. A touch switch 5, which cooperates with the contact rod 7, is installed on the end face of the second connecting member 4. The touch switch 5 is connected to the central locking system of the vehicle. The two end plates 2 are used to control the two ends of the buffer rubber 1. The surface is protected to reduce damage to the stress surface of the buffer rubber 1. At the same time, when the suspension shock absorber is compressed, the buffer rubber 1 will be compressed, and the distance between the two end plates 2 will be closer. When the buffer rubber 1 is damaged or its elasticity is insufficient for cushioning due to long-term use, the buffer rubber 1 will deform, causing the buffer rubber 1 to be compressed shorter. This will cause the contact rod 7 to come into contact with the touch switch 5. The touch switch 5 sends a damage signal to the vehicle's central control system, allowing the driver to understand the status of the buffer rubber 1 and replace it in time.
[0024] One end plate 2 is fixedly connected to the outer wall of a third connector 8, and the other end plate 2 is fixedly connected to the outer wall of a fourth connector 9. A limit sleeve 11 is installed on the end face of the third connector 8, and a slide rod 10 is installed on the end face of the fourth connector 9 and slidably connected to the inner wall of the limit sleeve 11. When the buffer rubber 1 is compressed, the slide rod 10 is driven to slide within the limit sleeve 11. The limit sleeve 11 restricts the slide rod 10. The limit sleeve 11 and the slide rod 10 restrict the end plate 2 through the third connector 8 and the fourth connector 9, respectively. In turn, the two end plates 2 restrict the buffer rubber 1, thereby limiting the lateral pressure of the buffer rubber 1 and improving the strength of the buffer rubber 1.
[0025] The third connector 8 has a perforation 12 on its side wall. The slide rod 10 moves through the perforation 12 to reduce the limitation of the minimum compression gap between the two end plates 2, so as to accommodate more length and elasticity of the buffer rubber 1 and improve adaptability.
[0026] The number of first connector 3, second connector 4, third connector 8 and fourth connector 9 are all two, and they are symmetrically distributed to improve the restriction on buffer rubber 1 and adapt to the elastic bending of buffer rubber 1, so as to ensure that a timely reminder is given by touch switch 5 when buffer rubber 1 is damaged.
[0027] Both ends of the buffer rubber 1 are provided with mounting grooves 13, and the end plate 2 is installed in the mounting grooves 13. Both ends of the outer wall of the buffer rubber 1 are provided with relief grooves 14. The first connector 3, the second connector 4, the third connector 8 and the fourth connector 9 are all installed in the relief grooves 14. Through the relief grooves 14, the first connector 3, the second connector 4, the third connector 8 and the fourth connector 9 all make way for the ends of the buffer rubber 1, which facilitates the installation and positioning of the buffer rubber 1. At the same time, the end plate 2 does not protrude from the buffer rubber 1 through the mounting grooves 13, avoiding long-term pressure and damage to the buffer rubber 1 caused by the end plate 2.
[0028] Both ends of the buffer rubber 1 have a relief opening 15 on their inner walls, and a limit opening 16 is provided on the inner wall of the relief opening 15. The side wall of the end plate 2 is fixedly connected with a retaining sleeve 17. The retaining sleeve 17 is movably engaged in the relief opening 15 and the limit opening 16. The end plate 2 is movably installed with the buffer rubber 1 through the retaining sleeve 17, which is convenient for disassembly and assembly, and easy for replacing the buffer rubber 1, so that it can be reused repeatedly.
[0029] The bottom surface of the adjusting plate 6 has a limiting groove 18. The contact rod 7 is slidably connected in the limiting groove 18. Two limiting blocks 19 are fixedly connected to the outer wall of the contact rod 7 and are slidably connected to the inner wall of the limiting groove 18. The limiting groove 18 restricts the contact rod 7 through the limiting blocks 19, so that the contact rod 7 will not rotate. The upper end of the adjusting plate 6 is rotatably connected to a bolt 20. The bolt 20 is threadedly connected to the inner wall of the contact rod 7. By rotating the bolt 20, the contact rod 7 can be adjusted to rise or fall, thereby adjusting the distance between the contact rod 7 and the touch switch 5 when the buffer rubber 1 is spread open, so as to adapt to the transmission of damage signals by buffer rubber 1 with different elasticity and different length.
[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
