[0002] With the increasing requirements for the driving comfort of automobiles, products such as electronic vacuum pumps and air-conditioning compressors have relatively large vibrations. When the motor drives the transmission mechanism to do work, vibrations and noises will inevitably be generated during the working process. Without a good shock absorption structure, the vibrations will be transmitted to the cab through the vehicle frame and pipelines, causing complaints from customers. Moreover, it will even reduce the strength of parts and shorten the service life of products. There will also be phenomena such as loosening and wear at the connection with the vehicle frame due to vibration, resulting in structural damage.

[0003] Many existing shock pad structures have too many cooperating parts, resulting in high requirements for parts, labor costs, and the dimensions of the cooperating parts. Therefore, it is necessary to design a shock absorption structure that can overcome the deficiencies of the existing structure, save costs, simplify the installation steps, refine the dimensions of the cooperating parts, have excellent shock absorption effect and long service life, and at the same time meet the installation requirements of different vehicle models.

[0004] The utility model patent with the authorization announcement number CN216478688U discloses a vehicle spring shock absorption structure. This shock absorption structure has excellent shock absorption effect and long service life, and can meet the installation requirements of different vehicle models and different positions at the same time. However, this shock absorption structure is relatively complex and inconvenient to install. Content of the Utility Model

[0027] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0028] The utility model provides a shock-absorbing structure, which solves the problem that the existing shock-absorbing structure is relatively complex and inconvenient to install. The shock-absorbing structure is suitable for vibration devices that generate large vibrations, such as electronic vacuum pumps and air-conditioning compressors, and this type of vibration device is suitable for vehicles, such as automobiles.

[0029] like Figure 1 and Figure 2 As shown, in one embodiment, a shock absorbing structure is provided, which has no less than three shock absorbing units 10, and all the shock absorbing units 10 are evenly distributed according to the center of gravity of the supporting structure, that is, all the shock absorbing units 10 are arranged on a circle with the center of gravity of the supporting structure as the center, and each shock absorbing unit 10 includes: an elastic shock absorbing integrated part 101 and a fixing part 102.

[0030] The elastic shock-absorbing integrated part 101 includes two elastic bodies 1011 and an elastic connecting piece 1012. Both of the two elastic bodies 1011 have through holes with different inner diameters on the same central axis Y. One of the elastic bodies is arranged in the through hole of the other elastic body. The elastic connecting piece 1012 is arranged in the cavity formed by the side walls of the two elastic bodies 1011 and is connected to the side walls of the two elastic bodies 1011 at both ends respectively; In an embodiment, the elastic shock-absorbing integrated part 101 is an integrated rubber shock-absorbing structure, including a first elastic body 1011A, a second elastic body 1011B, an elastic connecting piece 1012 and a reinforcing rib 1013. Both the first elastic body 1011A and the second elastic body 1011B have through holes with different inner diameters on the same central axis Y. The second elastic body 1011B extends in the vertical direction and is arranged in the through hole of the first elastic body 1011A. The first elastic body 1011A has an extension part extending in the horizontal direction and grooves are engraved on its outer side wall; The elastic connecting piece 1012 is arranged in the cavity formed by the side walls of the first elastic body 1011A and 1011B. One end of the elastic connecting piece 1012 is connected to a certain horizontal plane on the inner side wall of the first elastic body 1011A, and the other end of the elastic connecting piece 1012 is connected to a certain horizontal plane on the outer side wall of the second elastic body 1011B; The reinforcing rib 1013 is arranged at the connection of the second elastic body 1011B and the elastic connecting piece 1012, which is used to improve the service life of the elastic shock-absorbing integrated part 101 and prevent the elastic connecting piece 1012 from being torn when receiving a large external horizontal force;

[0031] The fixing piece 102 is arranged in the through hole of the elastic shock-absorbing integrated part 101 to fix the position of the shock-absorbing unit 10; In an embodiment, the fixing piece 102 is arranged in the through hole of the second elastic body 1011B. The cross-sectional width of the end of the fixing piece 102 far from the second elastic body is greater than the aperture of the second elastic body 1011B, thereby forming a limiting part that restricts the axial movement of the elastic shock-absorbing integrated part 101 along the fixing piece 102, so as to play the role of fixing and guiding the shock-absorbing unit 10; In an embodiment, the fixing piece 102 adopts a bolt, which plays the role of fixing and guiding. The elastic shock-absorbing integrated part 101 that is installed in cooperation with the fixing piece makes the dimensions of the matching parts of the shock-absorbing structure more refined, saves costs and simplifies the installation steps; In an embodiment, the fixing piece 102 is made of a material with a certain strength, such as hard metal materials such as steel and aluminum, so as to play the role of connection and bearing impact.

[0032] As Figure 2 shown, in an embodiment, when the shock-absorbing structure is in a normal state, the relative positions of the first elastic body 1011A and the second elastic body 1011B remain unchanged in the vertical direction, and there is a first gap 1014 between the first elastic body 1011A and the second elastic body 1011B in the horizontal direction.

[0033] As shown Figure 4 In an embodiment, when the shock-absorbing structure is in a vertically stressed state, the first elastic body 1011A and the second elastic body 1011B generate relative displacement in the vertical direction. The second elastic body 1011B can perform reciprocating rebound movement up and down relative to the first elastic body 1011A. The first elastic body 1011A and the second elastic body 1011B have a first gap 1014 in the horizontal direction, thereby effectively weakening the transmission of vibration in the vertical direction.

[0034] As shown Figure 5 In an embodiment, when the shock-absorbing structure is in a horizontally stressed state, the relative positions of the first elastic body 1011A and the second elastic body 1011B in the vertical direction remain unchanged, and the first elastic body 1011A and the second elastic body 1011B are in a contact or extrusion state in the horizontal direction, thereby effectively weakening the transmission of vibration in the horizontal direction.

[0035] As shown Figure 6 In an embodiment, when the shock-absorbing structure is in a horizontally and vertically stressed state, the first elastic body 1011A and the second elastic body 1011B generate relative displacement in the vertical direction, and the first elastic body 1011A and the second elastic body 1011B are in a contact or extrusion state in the horizontal direction.

[0036] As shown Figure 3 In an embodiment, the shock-absorbing structure further includes a flat plate member 20 that connects all shock-absorbing units to the vibration device 30. The flat plate member 20 has a connecting inner hole with an unlimited shape, and the structure and shape of the flat plate member 20 are not specifically limited. In an embodiment, the flat plate member 20 has a connecting inner hole 201, and the edge of the connecting inner hole 201 is embedded in the groove on the outer side wall of the first elastic body 1011A, thereby effectively restricting the movement range of the shock-absorbing unit 10. In an embodiment, the number of the connecting inner holes 201 is at least 3 and evenly distributed. The center of gravity of the connecting inner holes 201 should be located at the center of the mounting bracket, and the center of gravity of the vibration device 30 should be basically consistent with the center of the distribution of the connecting inner holes 201, which can more effectively weaken the vibration transmission.

[0037] As shown Figure 2As shown, in one embodiment, the fixing member 102 passes through the through hole of the elastic shock-absorbing integral member 101 and is fixedly connected to the mounting hole 301 of the vibration device 30 to facilitate subsequent maintenance, disassembly and replacement; in one embodiment, the bottom surface of the upper end of the fixing member 102 contacts the top surface of the second elastic body 1011B to form a first limiting surface 103, and the bottom surface of the second elastic body 1011B contacts the top surface of the mounting hole 301 to form a second limiting surface 302; in one embodiment, the mounting hole 301 is made of a material with a certain strength, such as hard metal materials such as steel and aluminum, so as to play a role in connection and bearing impact; in one embodiment, the vibration device 30 is a device that generates large vibrations, such as an electronic vacuum pump, an air-conditioning compressor, etc.

[0038] The utility model has a simple structure. Through the design structure that the elastic shock-absorbing integrated part 101 can rebound up and down and swing left and right when subjected to force, it can reduce the vibration transmission of the vibration device in the horizontal and vertical directions and can effectively reduce the noise and vibration generated by the vibration device.

[0039] The above description is merely a preferred embodiment of one or more embodiments of the present specification and is not intended to limit one or more embodiments of the present specification. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of the present specification shall be included in the scope of protection of one or more embodiments of the present specification.
