[0002] The top mount is a component configured on the shock absorber, commonly known as the shock absorber support with a spring seat ring. The main structure of the shock absorber is a shock cylinder, and the main component of the top mount body is the rubber part, which buffers through rubber elasticity to improve the comfort of vehicle riding. At the same time, it also reduces the tire noise generated between the tire and the ground. When the tire is jolted by a rough road surface, it can reduce the direct impact force on the vehicle. After the top mount is damaged, the direction will become skewed, that is, when driving straight, the steering wheel is crooked, and it will not go straight when straightened. Moreover, when driving on an uneven road surface, each top mount bears an impact force exceeding one-fourth of the vehicle body weight.
[0003] In the prior art, during the shock absorption process of the automotive shock absorber top mount, the shock absorber top mount bears the impact force of the spring through a metal seat, and the shock absorber spring is likely to cause damage to the shock absorber top mount. The shock absorber top mount has defects such as low service life of the shock absorber and increased equipment and maintenance costs. Content of the Utility Model
[0004] Aiming at the above-mentioned shortcomings of the prior art, the utility model provides a new type of automotive shock absorber top mount, which can effectively solve the problem that the shock absorber spring is likely to cause damage to the shock absorber top mount during the shock absorption process of the automotive shock absorber in the prior art.
[0005] To achieve the above purposes, the utility model is realized through the following technical solutions:
[0006] The utility model provides a new type of automotive shock absorber top mount, including a top mount body. A central hole is provided in the central part of the top mount body. An upper convex platform is connected and arranged at the upper end of the top mount body. A positioning groove communicating with the central hole is provided on the upper convex platform. A lower convex platform is provided at the lower end of the top mount body. Mounting holes are provided at the four corners of the top mount body. Fixing bolts are threadedly connected to each mounting hole. Two connecting blocks are symmetrically and fixedly connected to the outside of the lower convex platform. A buffer groove is provided at the lower end of the top mount body, and the two connecting blocks are slidably connected to the buffer groove. A plurality of longitudinal buffer springs are fixedly connected between the connecting blocks and the buffer groove. A limiting groove communicating with the buffer groove is further provided at the lower end of the top mount body. Two sliders are symmetrically and slidably connected in the limiting groove. A connecting rod is provided between the slider and the connecting block, and the connecting rod is rotatably connected to both the connecting block and the slider. A plurality of transverse buffer springs are fixedly connected between the slider and the limiting groove.
[0007] According to the above-mentioned novel automobile shock absorber top glue, a bearing is arranged at the center hole of the top glue body, and the outer ring of the bearing is fixedly connected to the inner peripheral wall of the center hole.
[0008] According to the above-mentioned novel automobile shock absorber top glue, a plurality of guide grooves connected with the limit grooves are also opened in the top glue body, and a plurality of guide rods slidably connected with the guide grooves are fixedly connected to the upper end of the connecting block.
[0009] According to the above-mentioned novel automobile shock absorber top glue, each of the longitudinal buffer springs is located on the outside of the guide rod, and the longitudinal buffer spring is always in a compressed state but not in an extreme compression state.

[0013] The utility model has multiple longitudinal buffer springs arranged between the connecting block and the buffer groove, and transverse buffer springs arranged between the limit grooves of the sliding block. When vibrated, the longitudinal buffer springs and the transverse buffer springs can absorb vibrations from two directions to reduce the shaking amplitude. At the same time, the longitudinal buffer springs and the transverse buffer springs can disperse the elastic force provided by the shock-absorbing spring to various parts of the buffer groove, thereby reducing the local pressure of the shock-absorbing spring on the top glue body, reducing the damage of the shock-absorbing spring to the top glue body, and improving the service life of the top glue body.

Detailed implementation manners
[0019] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] The present utility model will be further described below with reference to the embodiments.
[0021] Embodiment: Refer to Figures 1 to 3 , a new type of top rubber for an automobile shock absorber, including a top rubber body 1. A central hole is provided at the central part of the top rubber body 1. An upper convex platform 2 is further connected and arranged at the upper end of the top rubber body 1. A positioning groove communicating with the central hole is provided on the upper convex platform 2. A bearing 4 is arranged at the central hole of the top rubber body 1, and the outer ring of the bearing 4 is fixedly connected with the inner peripheral wall of the central hole. When the central shaft of the shock absorber rotates, the top rubber body 1 will not be subjected to the rotational force from the central shaft, reducing the damage to the top rubber of the shock absorber by the central shaft and improving the service life of the top rubber of the shock absorber.
[0022] A lower convex platform 3 is arranged at the lower end of the top rubber body 1. The upper convex platform 2 and the lower convex platform 3 are both made of plastic rubber, and the damage to the top rubber body 1 is reduced by the elastic rubber material itself.
[0023] Mounting holes are provided at the four corners of the top rubber body 1, and fixing bolts 5 are threadedly connected to each mounting hole. Two connecting blocks 7 are symmetrically and fixedly connected to the outside of the lower convex platform 3. A buffer groove 6 is provided at the lower end of the top rubber body 1, and the two connecting blocks 7 are slidably connected with the buffer groove 6. A plurality of longitudinal buffer springs 13 are fixedly connected between the connecting block 7 and the buffer groove 6. A plurality of guiding grooves 14 communicating with the limiting groove 9 are further provided in the top rubber body 1. A plurality of guiding rods 15 slidably connected with the guiding grooves 14 are fixedly connected to the upper end of the connecting block 7. By providing the sliding connection between the guiding rod 15 and the guiding groove 14, the vertical movement of the lower convex platform 3 is guided, ensuring the stability of the movement of the lower convex platform 3 during vibration.
[0024] Each longitudinal buffer spring 13 is located on the outside of the guide rod 15, so as to avoid the longitudinal buffer spring 13 from easily generating elastic deformation and increase the service life of the longitudinal buffer spring 13. The longitudinal buffer spring 13 is always in a compressed state but not in an extreme compression state. By keeping the longitudinal buffer spring 13 in a compressed state at all times, the stability of the position of the lower boss 3 is ensured. The longitudinal buffer spring 13 is never in an extreme compression state in order to avoid elastic fatigue of the longitudinal buffer spring 13.
[0025] The top glue body 1 is symmetrically provided with two pairs of limiting protrusions 8 for limiting the connecting block 7 in the buffer groove 6, and the limiting protrusions 8 abut against the connecting block 7 to avoid limiting the connecting block 7 and preventing the connecting block 7 from escaping from the buffer groove 6, thereby ensuring the stability of the connection between the lower boss 3 and the top glue body 1.
[0026] A limiting groove 9 connected to the buffer groove 6 is also provided at the lower end of the top glue body 1. Two sliders 10 are symmetrically slidably connected in the limiting groove 9. A connecting rod 12 is arranged between the slider 10 and the connecting block 7. The connecting rod 12 is rotatably connected to the connecting block 7 and the slider 10. A plurality of transverse buffer springs 11 are fixedly connected between the slider 10 and the limiting groove 9. The two sliders 10 move horizontally and cooperate with the connecting plate 7 to disperse the elastic force on the shock-absorbing spring to various parts of the buffer groove 6, thereby reducing the local pressure of the shock-absorbing spring on the top glue body 1, reducing the pressure loss of the shock-absorbing spring on the shock absorber top glue, and improving the service life of the shock absorber top glue.
[0027] The working principle of the utility model is as follows:
[0028] A buffer groove 6 is opened at the lower end of the top glue body 1, and a plurality of longitudinal buffer springs 13 are arranged between the connecting block 7 on the lower boss 3 and the buffer groove 6, in cooperation with a connecting rod 12 rotatably connected to the side of the connecting block 7, and a slider 10 rotatably connected to the connecting rod 12. The slider 10 slides horizontally in the limiting groove 9. The longitudinal buffer spring 13 and the transverse buffer spring 11 can disperse the elastic force provided by the shock-absorbing spring to various parts of the buffer groove 6, thereby reducing the local pressure of the shock-absorbing spring on the top glue body 1 and reducing the damage of the shock-absorbing spring to the top glue body 1.
