Description

Technical Field

[0001] The present application relates to the technical field of engine shock absorbers, and in particular to an engine shock absorber mechanism. Background Art

[0002] The main function of the engine shock absorber is to reduce the vibration generated when the engine is working, ensure the stability of the vehicle and improve the ride comfort. Damage to the shock absorber will increase the vibration of the vehicle and affect the smoothness of the ride. Therefore, the engine shock absorber is an indispensable component in automotive engineering, ensuring the effective isolation between the power system and the vehicle body, and reducing the impact of vibration on the vehicle structure and passenger comfort.

[0003] The applicant proposed an engine shock absorber mechanism that can extend the service life in 2016, and its announcement number is CN206234304U. The technology proposes an engine shock absorber mechanism mainly composed of an upper cover, a lower cover, a base and rubber. The base includes an upper plate and a side plate, and the upper cover, rubber, lower cover and base are integrally vulcanized and connected.

[0004] In view of the above-mentioned related technologies, the present application has found in long-term product follow-up that the part where the upper plate and the rubber are connected is provided with a perforation, and the middle of the rubber passes through the upper plate through the perforation, that is, the middle part of the rubber mainly relies on the bonding force generated during vulcanization and the shear force coordinated with the perforation to achieve the fixation between the rubber and the upper plate. After the rubber is subjected to vibration shock for a long time and frequently, material fatigue is easy to occur, resulting in the part where the rubber and the upper plate surface are bonded to peel off easily, affecting the connection effect between the rubber and the upper plate, so it needs to be improved. Summary of the invention

[0008] By adopting the above technical solution, the upper cover, the lower cover, the base and the rubber can form an engine shock absorber mechanism. The limit plate can be used to further increase the connection area between the rubber and the upper plate, greatly increase the connection strength between the upper plate and the rubber, and the limit plate can also limit the horizontal shear force between the rubber and the upper plate, further ensuring the connection strength between the upper plate and the rubber.

[0015] Optionally, an inner groove is provided on the side wall of the rubber, and the side of the limiting block close to the rubber is inserted into the inner groove.

[0016] By adopting the above technical solution, the inner groove can increase the connection area between the rubber and the limiting block, improve the connection strength between the rubber and the limiting block, and moreover, when connecting the rubber and the limiting block as a whole, the inner groove can be used for positioning and installing the limiting block.

[0017] Optionally, a nut is provided inside the rubber, bolts are inserted into each of the limiting blocks, the bolt body is threadedly connected to the nut, and the bolt nut is clamped to the side of the limiting block away from the rubber.

[0018] By adopting the above technical solution, the cooperation between the bolt and the nut can achieve the detachable connection between the limiting block and the rubber, and at the same time it can be used for optimizing the traditional engine shock absorber mechanism.

[0019] Optionally, a number of reinforcing grooves are provided on both the upper and lower surfaces of the upper plate, and a number of reinforcing ridges are provided on the rubber and are respectively embedded in each of the reinforcing grooves.

[0020] By adopting the above technical solution, the cooperation between the reinforcing grooves and the reinforcing ridges can further increase the connection strength between the rubber and the upper plate.

[0021] Optionally, the limiting plate is formed by welding a metal plate to the upper plate

[0022] By adopting the above technical solution, it is possible to directly complete the improvement by welding a metal plate on the traditional engine shock absorber mechanism.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. It can greatly increase the connection strength between the rubber and the upper plate, making it difficult for the bonded part of the rubber and the upper plate surface to peel off, and ensuring the connection effect between the rubber and the upper plate;

[0025] 2. It can be used for improvement in the traditional engine shock absorber mechanism, enabling the traditional engine shock absorber mechanism that has been produced and stored in inventory to be upgraded at a relatively low cost. BRIEF DESCRIPTION OF THE DRAWINGS
