Their main function is to reduce the impact and vibration from road irregularities, driving operations, engine operation, etc., to improve the comfort and safety of the vehicle, while protecting various components of the vehicle from damage. Buffer rubber parts usually work by absorbing and dissipating impact energy, thereby reducing the vibration transmitted to the vehicle body, wheels and other mechanical components.

[0029] Refer to Figure 2 - Figure 3 Buffer assembly 3 includes column 31, column 31 is slidably connected in the inside of mounting groove 2, the bottom surface of column 31 is hinged with multiple groups of array distribution support plate 32, the bottom end of support plate 32 is hinged with moving seat 33, the side wall of moving seat 33 is set with through hole, guide rod 34 is slidably connected in through hole, support plate 32 is used to support the bottom end of column 31, the action of moving seat 33 is slidably connected with guide rod 34, keep the stability of support plate 32, when column 31 is impacted, by the change of the inclination of support plate 32, moving seat 33 is slid along the axial direction of guide rod 34, guide rod 34 plays the role of guiding and restricting moving seat 33, ensure that the movement trajectory of moving seat 33 does not deviate from predetermined range, to improve the stability of overall buffering effect.

[0030] Refer to Figure 2 - Figure 3One end of the guide rod 34 is fixedly connected to the inner wall of the mounting groove 2, the other end of the guide rod 34 is fixedly connected with the fixed seat 35, the fixed seat 35 is fixedly connected to the inner wall of the mounting groove 2, the fixed seat 35 cooperates with the inside of the mounting groove 2, and the two ends of the guide rod 34 are fixed. The moving seat 33 is elastically connected to the inner wall of the mounting groove 2 through the return spring 36. By moving the moving seat 33, the return spring 36 is compressed under pressure, so as to buffer the impact force received by the stand column 31, and after the external impact force disappears, the stand column 31 returns to the original position, ready for the next impact. The bottom of the stand column 31 and the inner wall of the mounting groove 2 are provided with a damping 37. The damping 37 functions to slow down the vibration during the sliding of the stand column 31. When the stand column 31 slides, the damping 37 generates friction or resistance, reducing the rebound force and unnecessary vibration during movement.

[0031] Referring to Figure 2 , Figure 4 The inside of the stand column 31 is slidably connected with a sliding rod 38, the sliding rod 38 is elastically connected to the inner wall of the stand column 31 through a rubber spring 39, the sliding rod 38 is located in the inside of the stand column 31 and the top position exceeds the height of the stand column 31, used for directly contacting with the impact force source, when the sliding rod 38 is subjected to the impact force, it shrinks to the inside of the stand column 31, the rubber spring 39 is compressed under force, and it itself has a certain internal resistance, thereby preliminarily buffering the impact force. The inner wall of the stand column 31 is provided with a plurality of arrayed arc-shaped grooves 310, the sidewall of the sliding rod 38 is provided with a through groove 311, the inside of the through groove 311 is slidably connected with two groups of symmetrically arranged moving plates 312, the two groups of moving plates 312 are elastically connected through a supporting spring 313, the through groove 311 provides a track for the movement and installation of the two groups of moving plates 312, and the two groups of moving plates 312 are supported by the elastic force of the supporting spring 313, so as to move away from each other.

[0032] Referring to Figure 4 The sidewall of the moving plate 312 is fixedly connected with an arc-shaped strip 314, the arc-shaped strip 314 is inserted into the inside of the arc-shaped groove 310. When the two groups of moving plates 312 move away from each other, the arc-shaped strip 314 is inserted into the arc-shaped groove 310, and when the sliding rod 38 is subjected to the impact force, the friction between the arc-shaped strip 314 and the arc-shaped groove 310 slows down the speed of the sliding rod 38, preventing the sliding rod 38 from moving too fast, thereby reducing the impact force.

[0033] Working principle: when the multi-point impact-resistant buffer rubber piece is impacted, the impact force first acts on the sliding rod 38, the sliding rod 38 slides into the inside of the stand column 31 after being impacted, and the rubber spring 39 is compressed to preliminarily absorb part of the impact force. With the sliding of the sliding rod 38, the two groups of moving plates 312 move away from each other under the action of the supporting spring 313, so that the arc-shaped strips 314 are in close contact with the arc-shaped grooves 310 and generate friction, further slowing down the moving speed of the sliding rod 38, thereby effectively dispersing and slowing down the impact force. At the same time, the stand column 31 also slides when it is impacted, through the interaction of the supporting plate 32 and the moving seat 33, and the elastic restoring force of the reset spring 36, so that the stand column 31 can quickly recover to the original position after being impacted, providing effective buffering for the next impact. In addition, the setting of the damper 37 further slows down the vibration in the sliding process of the stand column 31, improving the stability of the overall buffering effect.
