Description

Technical Field

[0001] The utility model relates to the technical field of engine shock absorption, in particular to a shock absorber. Background Art

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. For example, internal combustion engines usually convert chemical energy into mechanical energy. In the automotive field, the engine needs to be fixed on the suspension beam of the frame. Since the engine itself will generate certain vibrations when it is working, there will also be certain vibrations when the car is driving on bumpy roads. The loads generated by these vibrations will act on the connection between the engine and the suspension beam. If the engine and the suspension beam are directly rigidly connected, it is easy to wear or even damage, so it is necessary to set a shock absorber between the engine and the suspension beam to absorb the impact load, thereby extending the service life.

[0003] The existing shock absorber adopts a structure in which rubber pads are arranged above and below the mounting seat, so that the shock absorber can only absorb the impact load in the vertical direction, that is, it can only absorb the impact load of the up and down vibration between the engine and the suspension beam. However, the car may also be subject to horizontal impacts during actual use. For example, when making turns quickly or under complex road conditions, the impact load in the horizontal direction between the engine and the suspension beam cannot be absorbed by the shock absorber, which may cause damage to the shock absorber and affect the reliability of the normal operation of the engine. Utility Model Content

[0013] In one embodiment, the supporting portion, the filling portion and the extending portion are all arranged in a cylindrical structure, and the central axes of the supporting portion, the filling portion and the extending portion are collinear and extend along a first direction.

[0014] In one embodiment, the second shock absorbing block is an integral piece.

[0040] See also Figures 1 to 4 The shock absorber 100 of one embodiment of the utility model comprises a mounting seat 10, a first shock absorbing block 20, a second shock absorbing block 30 and a locking member 40. The mounting seat 10 is used to be connected and fixed to the engine 90, and the mounting seat 10 has a plug hole 15, which passes through the mounting seat 10 on two opposite sides in the first direction; it should be noted that according to Figure 1 As shown, in the embodiment of the utility model, there is an X-axis direction, which is the direction in which the engine 90 bears the vertical impact load due to the up and down vibration. For the convenience of explanation, the first direction is defined as the X-axis direction. The first shock absorbing block 20 is elastically abutted against the mounting seat 10, and the first shock absorbing block 20 is arranged on one side of the mounting seat 10 in the first direction.
