Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically to a high-efficiency shock absorber buffer block for automotive shock absorbers. Background Technology

[0002] A car shock absorber bumper (also known as a damping rubber, limiter bumper, or integrated shock absorber dust cover / bumper) is a seemingly insignificant but very important rubber (or polyurethane and other elastic materials) component. It acts as a limiter and absorbs and buffers most of the impact energy before the internal components of the shock absorber collide, preventing the shock absorber from being damaged by a "bottoming out" collision and extending the life of the shock absorber. The original metallic collision sound is reduced due to the presence of the bumper. However, it is also a vulnerable part of the vehicle. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings. A high-efficiency shock-absorbing automotive shock absorber buffer block includes a body 1, with an axially extending mounting groove 2, and several elastic buffer walls 3 disposed on the bottom end face of the body for contact with the top mount 8. Gap grooves 31 are provided between adjacent buffer walls. Compared to ordinary buffer block structures, the portion in contact with the top mount enhances the buffer area. The petal-like structure of the buffer walls in contact with the top mount significantly reduces the deformation of the buffer block body during collisions. The outward expansion of the buffer walls under pressure also prevents deformation of the buffer block, thereby extending its lifespan. Simultaneously, it achieves smoother deformation and improves the vehicle's NVH performance.

[0021] In this embodiment, as shown in the figure, the buffer wall includes a connecting end 32 connected to the body and an extending end 33 for contacting the top adhesive. The arc length of the extending end is greater than the arc length of the connecting end. The overall structure, with a larger outer end and a smaller inner end, resembles a fan-shaped ring, and the annular wall extends along the axial direction of the body.

[0022] In this embodiment, as shown in the figure, there are four buffer walls.

[0023] In this embodiment, as shown in the figure, the buffer walls are arranged symmetrically about the axis of the main body.

[0024] In this embodiment, as shown in the figure, the inner wall of the mounting groove is provided with several protrusions 21. The protrusions are added at the top and bottom of the through hole to increase the friction between the buffer block and the damper shaft.

[0025] In this embodiment, as shown in the figure, the buffer wall is provided with reinforcing ribs.

[0026] In this embodiment, as shown in the figure, the outer circumferential wall of the main body is provided with a reinforcing ring 11 made of metal. The reinforcing ring is made of aluminum, which has better strength for the same volume compared to traditional plastic reinforcing rings. The reinforcing ring also features metal perforations, further reducing weight while adding reinforcing ribs, making the structure more stable and improving the overall performance of the buffer block, thus extending its service life. During vehicle operation, the shock absorption system operates in a relatively enclosed environment due to the interaction between the buffer block and the dust cover. The buffer block generates heat during its shock absorption process. Compared to plastic reinforcing rings, the metal reinforcing ring conducts heat better, and the perforated portion increases the heat dissipation area, optimizing the working environment of the buffer block to a certain extent. This extends the thermal aging process of the buffer block, thus prolonging its lifespan.

[0027] In this embodiment, as shown in the figure, the reinforcing ring is provided with a plurality of grooves 111.

[0028] In this embodiment, as shown in the figure, the reinforcing ring is made of aluminum.

[0029] In this embodiment, as shown in the figure, a buffer chamber 15 is provided at the front end of the mounting groove. A buffer chamber is added at the top, reserving a portion of space as a gas buffer chamber. The air pressure prevents further deformation of the buffer block and improves the lifespan of the buffer block.
