Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

A matrix type shock absorber with triangular shock absorption units is disclosed, referring to fig. 1-4, comprising a lower shell 1 and an upper shell 2 sleeved on the lower shell 1 and capable of lifting relative to the lower shell 1, a plurality of triangular shock absorption units 3 distributed in a matrix form are arranged between the upper shell 2 and the lower shell 1, each triangular shock absorption unit 3 comprises an upper backing plate 301 fixed at the bottom of the upper shell 2, a lower backing plate 302 fixed at the bottom of the lower shell 1 and three springs 303 with two ends respectively fixed with the upper backing plate 301 and the lower backing plate 302, the three springs 303 are respectively positioned on three vertexes of a triangle, the upper backing plate 301 and the lower backing plate 302 are preferably in a round shape with the same size as the upper and the lower, and are respectively fixed between the upper shell 2 and the lower shell 1 by welding, and the three springs 303 in each triangular shock absorption unit 3 are preferably distributed around the circumference of the upper backing plate 301 at even intervals, thus, the three springs 303 are located at the three vertices of an equilateral triangle.

For traditional a spring 303 from becoming a shock-absorbing unit, this scheme is by upper padding plate 301, lower bolster 302 and three springs 303 that are triangular distribution form a triangle shock-absorbing unit 3, receive pressure when triangle shock-absorbing unit 3 after, the compression of different degrees or torsion take place for three springs 303 of inside, but can interact carry out the compensation of doing all can between the three, thereby offset horizontal dislocation power, make and be the trend of vertical lift between upper padding plate and the lower bolster, lateral shifting has been avoided taking place between upper casing 2 and the lower casing 1, guarantee that the bumper shock absorber can continuously keep good damping performance, thereby increase of service life.
