Description

Technical Field

[0001] This application relates to the technical field of shock-absorbing components, and more particularly, to a shock-absorbing pad and a shock-absorbing pad assembly. Background Art

[0002] In order to cool the interior environment of a vehicle, a cooling device is generally installed in the vehicle. When the vehicle is running, the cooling device will vibrate with the bumps of the vehicle, and collisions will occur at the connection position between the cooling device and the vehicle body, generating noise. To this end, currently, a shock-absorbing pad is usually used to connect the cooling device to the vehicle body. However, the existing shock-absorbing pads can generally only play a shock-absorbing role in the thickness direction of the shock-absorbing pad, and it is difficult to play a shock-absorbing role in other directions. Summary of the Invention

[0003] The purpose of this application is to provide a shock-absorbing pad and a shock-absorbing pad assembly for the problem that the existing shock-absorbing pads can generally only play a shock-absorbing role in the thickness direction of the shock-absorbing pad, and it is difficult to play a shock-absorbing role in other directions.

[0004] To achieve the above purpose, this application adopts the following technical solutions:

[0005] One aspect of this application provides a shock-absorbing pad, including a base connection part, a housing connection part, and shock-absorbing ribs; both the base connection part and the housing connection part are cylindrical structures, the base connection part and the housing connection part are sleeved together, and the base connection part and the housing connection part are in clearance fit. The shock-absorbing ribs are installed in the gap between the base connection part and the housing connection part. One end of the shock-absorbing rib is connected to the base connection part, and the other end is connected to the housing connection part. The shock-absorbing rib is an elastic structure.

[0006] Optionally, the length extension direction of the shock-absorbing rib is inclined with respect to the axis of the base connection part.

[0007] The beneficial effect of this technical solution is that: in the length direction of the shock-absorbing rib, the shock-absorbing rib can generate a large range of elastic force changes, and thus can provide a large range of buffering. This is the main direction for the shock-absorbing rib to be used for shock absorption. Compared with making the length direction of the shock-absorbing rib only the axial or radial direction of the base connection part, making the length extension direction of the shock-absorbing rib inclined with respect to the axis of the base connection part enables the elastic force generated by the shock-absorbing rib in its length to generate both an axial component and a radial component, and thus better buffering effects can be obtained in both the axial and radial directions.

[0008] Optionally, the length extension direction of the shock-absorbing rib intersects with the axis of the base connection part.

[0009] The beneficial effect of this technical solution is that: this enables the shock-absorbing rib to be mainly used for shock absorption in the axial and radial directions of the base connection part.

[0010] Optionally, there are at least two shock absorbing ribs.

[0011] The beneficial effect of this technical solution is that more than one and an appropriate number of shock-absorbing ribs can provide a better shock-absorbing effect.

[0012] Optionally, there are four shock absorbing ribs, and the shock absorbing ribs are evenly distributed in the circumferential direction of the base connecting part.

[0013] The beneficial effect of this technical solution is that a more ideal shock-absorbing effect is obtained.

[0014] Optionally, the shock absorbing rib has a first surface and a second surface, the first surface is arranged facing the base connecting portion, and the second surface is arranged away from the base connecting portion;

[0015] The shock-absorbing pad has a longitudinal section, the longitudinal section intersects with the first surface to form a first intersection line, and the longitudinal section intersects with the second surface to form a second intersection line;

[0016] The angle between the first intersection line and the axial direction of the base connection portion is greater than or equal to 10 degrees and less than or equal to 40 degrees, and the angle between the second intersection line and the axial direction of the base connection portion is greater than or equal to 10 degrees and less than or equal to 40 degrees.

[0017] The beneficial effect of this technical solution is that: assuming that the axial direction of the base connecting part is the Z direction, the X direction and the Y direction are two directions perpendicular to the Z direction, and the X direction and the Y direction are perpendicular to each other, and by setting the positional relationship between the shock-absorbing rib and the base connecting part, the stiffness of the shock-absorbing pad in the three directions of Z, X and Y is basically consistent, and thus the shock-absorbing effect of the shock-absorbing pad in these three directions can be basically consistent.

[0018] Optionally, the angle between the first intersection line and the axial direction of the base connection part is greater than or equal to 20 degrees and less than or equal to 30 degrees, and the angle between the second intersection line and the axial direction of the base connection part is greater than or equal to 20 degrees and less than or equal to 30 degrees.

[0019] The beneficial effect of this technical solution is that it makes the stiffness of the shock-absorbing pad in the above three directions closer, and the shock-absorbing effect that can be achieved is more consistent.

[0020] Optionally, the angle between the first intersection line and the axial direction of the base connecting portion is 21 degrees.

[0021] The beneficial effect of this technical solution is that it makes the stiffness of the shock-absorbing pad in the above three directions closer, and the shock-absorbing effect that can be achieved is more consistent.

[0022] Optionally, the angle between the second intersection line and the axial direction of the base connecting portion is 24 degrees.

[0023] The beneficial effect of this technical solution is that this makes the stiffness of the shock pad closer in the above three directions, and the achievable shock absorption effect is more consistent.

[0024] When the included angle between the first intersection line and the axis of the base connection part is 21 degrees, and the included angle between the second intersection line and the axis of the base connection part is 24 degrees, the stiffness of the shock pad in the above three directions is the closest or almost the same, and the achievable shock absorption effect is the closest or almost the same.

[0025] Optionally, it includes a first limiting part and a second limiting part. One end in the axial direction of the housing connection part is connected with the first limiting part, and the other end in the axial direction of the housing connection part is connected with the second limiting part. Both the first limiting part and the second limiting part are elastic structures.

[0026] The beneficial effect of this technical solution is that during the operation of the whole vehicle, collisions or squeezes usually occur between the two ends of the shock pad in the axial direction and the outside. When the first limiting part and the second limiting part are provided, such collisions and squeezes will be buffered by the first limiting part and the second limiting part, and thus a better shock absorption effect can be obtained.

[0027] Optionally, both the base connection part and the housing connection part are elastic structures.

[0028] The beneficial effect of this technical solution is that thus the whole shock pad can play a shock absorption role.

[0029] Another aspect of the present application provides a shock pad assembly, including the above-mentioned shock pad. The housing is a cylindrical structure, and the housing is sleeved outside the housing connection part. The housing is fixedly connected with the housing connection part, and the housing is a rigid structure and is used for being fixed to the module.

[0030] Optionally, the housing connection part includes an integral section distributed in the axial direction and a split section connected to the integral section. There are at least two split sections, and each split section is distributed along the circumferential direction of the integral section, and a clamping slot is formed between two adjacent split sections; the number of shock-absorbing ribs corresponds to the number of split sections, and each shock-absorbing rib is connected to each split section in a one-to-one correspondence.

[0031] The beneficial effect of this technical solution is that this enables the split section to be connected with a dedicated shock-absorbing rib, thereby appropriately increasing the deformation range of the split section and the shock-absorbing rib, and further obtaining a larger elastic force change range, and further improving the shock absorption effect.

[0032] Optionally, the shock pad includes a first limiting part, and the first limiting part is installed at one end of each split section away from the integral section.

[0033] Optionally, a stepped structure is formed between the first limiting portion and the split section.

[0034] Optionally, first limiting protrusions are formed on the inner wall of the housing. The number of the first limiting protrusions is the same as the number of the clamping slits, and each of the first limiting protrusions is in clamping engagement with each of the clamping slits in a one-to-one correspondence.

[0035] The beneficial effect of this technical solution is that during the operation of the whole vehicle, circumferential torsion may occur between the shock pad and the housing. The cooperation between the first limiting protrusions and the clamping slits can share this torsion, thereby improving the connection reliability between the shock pad and the housing.

[0036] Optionally, second limiting protrusions are formed on the outer wall of the base connection portion. The number of the second limiting protrusions is the same as the number of the first limiting protrusions, and each of the first limiting protrusions is disposed opposite to each of the second limiting protrusions in a one-to-one correspondence.

[0037] The beneficial effect of this technical solution is that during the operation of the whole vehicle, if the base connection portion moves relative to the housing connection portion and causes the first limiting protrusions to collide with the second limiting protrusions, a certain shock-absorbing effect can also be generated between the first limiting protrusions and the second limiting protrusions.

[0038] Optionally, it includes a lining. The lining includes an insertion section and a limiting section that are both cylindrical. The insertion section and the limiting section are axially distributed and coaxially arranged. The insertion section is located inside the base connection portion. The cross-sectional diameter of the limiting section is larger than the inner diameter of the base connection portion, and the limiting section abuts against the base connection portion. The lining is a rigid structure and is used for fixedly connecting with the base.

[0039] The beneficial effect of this technical solution is that when the lining is used to indirectly connect the whole vehicle and the shock pad, it is relatively easy to connect the lining and the shock pad together by using a vulcanization molding process, and the inner side of the rigid structure is connected to the whole vehicle to obtain an ideal connection strength.

[0040] Optionally, the lining has a first inner hole that axially penetrates the insertion section and the limiting section.

[0041] The beneficial effect of this technical solution is that this enables a rod-shaped connecting piece such as a bolt to penetrate the first inner hole to connect the shock pad assembly and the whole vehicle.

[0042] Optionally, it includes a gasket installed on the limiting section. The gasket includes a disc portion and a protrusion portion. The protrusion portion is installed at the center of the disc portion. The protrusion portion is fixedly connected to the first inner hole. The diameter of the disc portion is larger than the inner diameter of the housing connection portion. The gasket has a second inner hole that axially penetrates the disc portion and the protrusion portion.

[0043] The beneficial effects of this technical solution are as follows: The relative displacement of the base connecting part and the housing connecting part in the axial direction can be restricted by the disc part, thereby limiting the vibration amplitude. The contact between the disc part and the second limiting part can further buffer the vibration and improve the shock absorption effect.

[0044] Optionally, the convex part has a first connection surface, and the inner lining has a second connection surface. The first connection surface and the second connection surface are fixedly connected, thereby realizing the connection between the separately formed inner lining and the gasket.

[0045] The beneficial effects of this technical solution are as follows: Separately forming the inner lining and the gasket can reduce the production difficulty compared with integrally forming the inner lining and the gasket, enabling more production environments to produce shock pads, which is convenient for the popularization and use of shock pads.

[0046] Optionally, the inner lining and the gasket are integrally formed.

[0047] The beneficial effects of this technical solution are as follows: Integrally forming the inner lining and the gasket can increase the strength after the inner lining and the gasket are formed into one body compared with separately forming the inner lining and the gasket, reduce the risk of loss of the inner lining and / or the gasket during transportation, facilitate storage, and also reduce the possibility of connection failure between the inner lining and the gasket during use, thereby improving the reliability of the shock pad. Moreover, integrally forming the inner lining and the gasket can also effectively shorten the production time of the shock pad and improve production efficiency.

[0048] Optionally, both the first inner hole and the second inner hole are oval holes.

[0049] The beneficial effects of this technical solution are as follows: When using a connecting piece, such as a bolt, to pass through the first inner hole and the second inner hole to connect the shock pad and the base, if both the first inner hole and the second inner hole are oval holes, a certain margin can be left between the connecting piece and the inner walls of the first inner hole and the second inner hole, making it easier for the connecting piece to extend into the first inner hole and the second inner hole and improving the assembly efficiency.

[0050] Optionally, both the first inner hole and the second inner hole are circular holes.

[0051] The beneficial effects of this technical solution are as follows: When using a connecting piece, such as a bolt, to pass through the first inner hole and the second inner hole to connect the shock pad and the base, if both the first inner hole and the second inner hole are circular holes, the connecting piece can fit more closely with the inner walls of the first inner hole and the second inner hole, and thus the connection between the shock pad and the base is more reliable.

[0052] The technical solution provided by this application can achieve the following beneficial effects:

[0053] When the shock pad and the shock pad assembly provided by this application are in use, the shock pad is connected to the base through the base connection part and to the module through the housing connection part. When the vehicle is running, since the base connection part and the housing connection part are connected by shock-absorbing ribs, the relative movement between the base connection part and the housing connection part, whether it is the movement in the axial direction of the base connection part or the movement in the radial direction of the base connection part, will be hindered by the elastic force generated by the shock-absorbing ribs. Correspondingly, the relative movement between the vehicle and the module will also be hindered, thereby reducing the vibration amplitude of the module relative to the vehicle, and playing a shock-absorbing role at least in the axial and radial directions of the base connection part.

[0088] The technical solution of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0090] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0091] As Figures 1 to 9 shown, an aspect of the present application provides a shock pad 300, which includes a base connection part 310, a housing connection part 350, and shock-absorbing ribs 330; both the base connection part 310 and the housing connection part 350 are cylindrical structures. The base connection part 310 and the housing connection part 350 are sleeved together, and the base connection part 310 and the housing connection part 350 are in clearance fit. The shock-absorbing ribs 330 are installed in the gap 380 between the base connection part 310 and the housing connection part 350. One end of the shock-absorbing rib 330 is connected to the base connection part 310, and the other end is connected to the housing connection part 350. The shock-absorbing rib 330 is an elastic structure.

[0092] In the embodiments of the present application, the base can be a whole vehicle, and the module can be a cooling device as a module. Of course, the shock pad 300 and the shock pad assembly can also be used to connect any two components to achieve the shock-absorbing effect at the connection between these two components; the base connection part, the housing connection part, and the shock-absorbing ribs can be integrally formed or produced separately and then assembled together.

[0093] When the shock pad 300 provided by the embodiment of the present application is in use, the shock pad 300 is connected to the base through the base connection part 310 and connected to the module through the housing connection part 350. When the vehicle is running, since the base connection part 310 and the housing connection part 350 are connected by the shock-absorbing ribs 330, the relative movement between the base connection part 310 and the housing connection part 350, whether it is the movement in the axial direction of the base connection part 310 or the movement in the radial direction of the base connection part 310, will be hindered by the elastic force generated by the shock-absorbing ribs 330. Correspondingly, the relative movement between the vehicle and the module will also be hindered, thereby reducing the vibration amplitude of the module relative to the vehicle, and playing a shock-absorbing role at least in the axial and radial directions of the base connection part 310.

[0094] Optionally, the length extension direction of the shock-absorbing rib 330 is inclined with respect to the axis of the base connection part 310.

[0095] In the length direction of the shock-absorbing rib 330, the shock-absorbing rib 330 can generate a large range of elastic force changes, and thus can provide a large range of buffering. This is the main direction for the shock-absorbing rib 330 to absorb shock. Compared with making the length direction of the shock-absorbing rib 330 only in the axial or radial direction of the base connection part 310, making the length extension direction of the shock-absorbing rib 330 inclined with respect to the axis of the base connection part 310 enables the elastic force generated by the shock-absorbing rib 330 in its length to generate both an axial component and a radial component, and thus better buffering effects can be obtained in both the axial and radial directions.

[0096] Optionally, the length extension direction of the shock-absorbing rib 330 intersects with the axial direction of the base connection part 310. This enables the shock-absorbing rib 330 to be mainly used for shock absorption in the axial and radial directions of the base connection part 310.

[0097] Optionally, there are at least two shock-absorbing ribs 330. More than one and an appropriate number of shock-absorbing ribs 330 can provide a better shock-absorbing effect.

[0098] Optionally, there are four shock-absorbing ribs 330, and the shock-absorbing ribs 330 are evenly distributed in the circumferential direction of the base connection part 310. Thus, a more ideal shock-absorbing effect can be obtained. Of course, one, three, or five shock-absorbing ribs 330 can also be set according to specific needs.

[0099] Optionally, as Figure 4 shown, the shock-absorbing rib 330 has a first surface 331 and a second surface 332. The first surface 331 faces the base connection part 310, and the second surface 332 faces away from the base connection part 310;

[0100] The shock pad 300 has a longitudinal section, and the longitudinal section intersects with the first surface 331 to form a first intersection line, and the longitudinal section intersects with the second surface 332 to form a second intersection line;

[0101] The included angle between the first intersection line and the axial direction of the base connection part 310 is greater than or equal to 10 degrees and less than or equal to 40 degrees, such as 12 degrees, 15 degrees, 18 degrees, 32 degrees, 35 degrees or 38 degrees, etc., and the included angle between the second intersection line and the axial direction of the base connection part 310 is greater than or equal to 10 degrees and less than or equal to 40 degrees, such as 12 degrees, 15 degrees, 18 degrees, 32 degrees, 35 degrees or 38 degrees, etc.

[0102] When there are four shock-absorbing ribs 330, assuming the axial direction of the base connection part 310 is the Z direction, the X direction and the Y direction are two directions perpendicular to the Z direction, and the X direction and the Y direction are perpendicular to each other. And by setting the positional relationship between the shock-absorbing ribs 330 and the base connection part 310, the stiffness of the shock-absorbing pad 300 in the three directions of the Z direction, the X direction and the Y direction is basically the same, so that the shock-absorbing effect of the shock-absorbing pad 300 in these three directions can basically reach the same.

[0103] Optionally, the included angle between the first intersection line and the axial direction of the base connection part 310 is greater than or equal to 20 degrees and less than or equal to 30 degrees, such as 22 degrees, 25 degrees or 28 degrees, etc., and the included angle between the second intersection line and the axial direction of the base connection part 310 is greater than or equal to 20 degrees and less than or equal to 30 degrees, such as 22 degrees, 25 degrees or 28 degrees, etc.

[0104] This makes the stiffness of the shock-absorbing pad 300 closer in the above three directions, and the shock-absorbing effect that can be achieved is more consistent.

[0105] Optionally, the included angle between the first intersection line and the axial direction of the base connection part 310 is 21 degrees.

[0106] This makes the stiffness of the shock-absorbing pad 300 closer in the above three directions, and the shock-absorbing effect that can be achieved is more consistent.

[0107] Optionally, the included angle between the second intersection line and the axial direction of the base connection part 310 is 24 degrees.

[0108] The beneficial effect of this technical solution is that: this makes the stiffness of the shock-absorbing pad 300 closer in the above three directions, and the shock-absorbing effect that can be achieved is more consistent.

[0109] When the included angle between the first intersection line and the axial direction of the base connection part 310 is 21 degrees, and the included angle between the second intersection line and the axial direction of the base connection part 310 is 24 degrees, the stiffness of the shock-absorbing pad 300 in the above three directions is closest or almost the same, and the shock-absorbing effect that can be achieved is closest or almost the same.

[0110] Optionally, the shock absorber pad 300 provided by the embodiments of the present application includes a first limiting portion 320 and a second limiting portion 360. One axial end of the housing connecting portion 350 is connected to the first limiting portion 320, and the other axial end of the housing connecting portion 350 is connected to the second limiting portion 360. Both the first limiting portion 320 and the second limiting portion 360 are elastic structures.

[0111] During the operation of the whole vehicle, collisions or squeezes usually occur between the two axial ends of the shock absorber pad 300 and the outside. When the first limiting portion 320 and the second limiting portion 360 are provided, such collisions and squeezes will be buffered by the first limiting portion 320 and the second limiting portion 360, thereby obtaining a better shock absorption effect. In particular, by adjusting the width, height, distribution and quantity of the first limiting portion 320 and the second limiting portion 360, the inflection point of the dynamic stiffness of the shock absorber pad can appear at an ideal compression point.

[0112] Optionally, both the base connecting portion 310 and the housing connecting portion 350 are elastic structures. Thus, the whole shock absorber pad 300 can play a shock absorption role.

[0113] Another aspect of the present application provides a shock absorber pad assembly, including a housing 100 and the shock absorber pad 300 provided by the embodiments of the present application. The housing 100 is a cylindrical structure, and the housing 100 is sleeved outside the housing connecting portion 350. The housing 100 is fixedly connected to the housing connecting portion 350. The housing 100 is a rigid structure and is used to be fixed to the module.

[0114] The shock absorber pad assembly provided by the embodiments of the present application adopts the shock absorber pad 300 provided by the embodiments of the present application. When in use, the shock absorber pad 300 is connected to the base through the base connecting portion 310, fixedly connected to the housing 100 through the housing connecting portion 350, and then indirectly connected to the module through the housing 100. When the whole vehicle is running, since the base connecting portion 310 and the housing connecting portion 350 are connected by the shock absorbing ribs 330, the relative movement between the base connecting portion 310 and the housing connecting portion 350, whether it is the movement in the axial direction of the base connecting portion 310 or the movement in the radial direction of the base connecting portion 310, will be hindered by the elastic force generated by the shock absorbing ribs 330. Correspondingly, the relative movement between the whole vehicle and the module will also be hindered, thereby reducing the vibration amplitude of the module relative to the whole vehicle, and playing a shock absorption role at least in the axial and radial directions of the base connecting portion 310; while the module is generally a metal or rigid structure, when the shock absorber pad 300 is an elastic structure, it is difficult to ensure the connection strength between the module and the shock absorber pad 300. The volume of the module is relatively large compared with the shock absorber pad 300. Using processes such as vulcanization molding to connect the module and the shock absorber pad 300 will bring great inconvenience. However, it is more convenient to connect the shock absorber pad 300 through the housing 100, and then connect to the module through the rigid housing 100, which can obtain an ideal connection strength and make the operation of the whole vehicle more reliable.

[0115] Optionally, the housing connection portion 350 includes an integral section 350a distributed axially and a split section 350b connected to the integral section 350a. There are at least two split sections 350b, and each split section 350b is circumferentially distributed along the integral section 350a, and a clamping slot 370 is formed between two adjacent split sections 350b; the number of the shock-absorbing ribs 330 corresponds to the number of the split sections 350b, and each shock-absorbing rib 330 is connected to the position of each split section 350b in a one-to-one correspondence. This enables the split section 350b to be connected to the dedicated shock-absorbing rib 330, thereby appropriately increasing the deformation range of the split section 350b and the shock-absorbing rib 330, and further obtaining a larger elastic force change range, and further improving the shock-absorbing effect. Of course, the number of the shock-absorbing ribs 330 does not necessarily correspond to the number of the split sections 350b.

[0116] Optionally, the shock-absorbing pad 300 includes a first limiting portion 320, and a first limiting portion 320 is installed at one end of each split section 350b away from the integral section 350a.

[0117] Optionally, a stepped structure is formed between the first limiting portion 320 and the split section 350b.

[0118] Optionally, a first limiting protrusion 110 is formed on the inner wall of the housing 100. The number of the first limiting protrusions 110 is the same as the number of the clamping slots 370, and each first limiting protrusion 110 is engaged with each clamping slot 370 in a one-to-one correspondence. When the whole vehicle is running, there may be a circumferential torque between the shock-absorbing pad 300 and the housing 100. The cooperation of the first limiting protrusion 110 and the clamping slot 370 can share this torque, thereby improving the connection reliability between the shock-absorbing pad 300 and the housing 100.

[0119] Optionally, a second limiting protrusion 340 is formed on the outer wall of the base connection portion 310. The number of the second limiting protrusions 340 is the same as the number of the first limiting protrusions 110, and each first limiting protrusion 110 and the second limiting protrusion 340 are oppositely arranged in a one-to-one correspondence. When the whole vehicle is running, if the base connection portion 310 moves relative to the housing connection portion 350 and causes the first limiting protrusion 110 to collide with the second limiting protrusion 340, a certain shock-absorbing effect can also be generated between the first limiting protrusion 110 and the second limiting protrusion 340. Of course, the number of the second limiting protrusions 340 may also be different from the number of the first limiting protrusions 110.

[0120] Optionally, the damping pad assembly provided by the embodiments of the present application includes a lining 200. The lining 200 includes an insertion section 210 and a limiting section 220 that are both cylindrical. The insertion section 210 and the limiting section 220 are axially distributed and coaxially arranged. The insertion section 210 is located within the base connection part 310. The cross-sectional diameter of the limiting section 220 is greater than the inner diameter of the base connection part 310, and the limiting section 220 abuts against the base connection part 310. The lining 200 is a rigid structure and is used for fixedly connecting with the base. Since the whole vehicle is usually made of rigid structures such as metal, when the damping pad 300 is an elastic structure, it is difficult to ensure the connection strength between the damping pad 300 and the whole vehicle. And because the whole vehicle is relatively large in volume, it is difficult to adopt processes such as vulcanization molding for connecting rigid structures and elastic structures. When the lining 200 is used to indirectly connect the whole vehicle and the damping pad 300, it is relatively easy to use the vulcanization molding process to connect the lining 200 and the damping pad 300 together, and connect the inner side of the rigid structure with the whole vehicle to obtain an ideal connection strength.

[0121] Optionally, the lining 200 has a first inner hole 400 that axially penetrates through the insertion section 210 and the limiting section 220. This enables a rod-shaped connecting piece such as a bolt to penetrate through the first inner hole 400 to connect the damping pad assembly and the whole vehicle.

[0122] Optionally, the damping pad assembly provided by the embodiments of the present application includes a gasket 500 mounted on the limiting section 220. The gasket 500 includes a disc portion 520 and a convex portion 510. The convex portion 510 is mounted at the center of the disc portion 520. The convex portion 510 is fixedly connected to the first inner hole 400. The diameter of the disc portion 520 is greater than the inner diameter of the housing connection part 350. The gasket 500 has a second inner hole that axially penetrates through the disc portion 520 and the convex portion 510. Through the disc portion 520, the relative displacement of the base connection part 310 and the housing connection part 350 in the axial direction can be restricted, thereby limiting the vibration amplitude. The abutment of the disc portion 520 against the second limiting portion 360 can further buffer the vibration and improve the damping effect. The gasket 500 is preferably a rigid structure.

[0123] Optionally, the convex portion 510 has a first connection surface, and the lining 200 has a second connection surface. The first connection surface and the second connection surface are fixedly connected, thereby realizing the connection between the separately formed lining 200 and the gasket 500. Separately forming the lining 200 and the gasket 500 can reduce the production difficulty compared to integrally forming the lining 200 and the gasket 500, enabling more production environments to produce the damping pad and facilitating the popularization and use of the damping pad.

[0124] Optionally, the inner liner 200 and the gasket 500 are integrally formed. Compared with separately forming the liner 200 and the gasket 500, integrally forming the inner liner 200 and the gasket 500 can increase the strength of the combination of the inner liner 200 and the gasket 500, reduce the risk of loss of the inner liner 200 and / or the gasket 500 during transportation, facilitate storage, and also reduce the possibility of connection failure between the inner liner 200 and the gasket 500 during use, thereby improving the reliability of the shock pad. Moreover, integrally forming the inner liner 200 and the gasket 500 can also effectively shorten the production time of the shock pad and improve production efficiency.

[0125] Optionally, both the first inner hole 400 and the second inner hole are oval holes. When using a connecting member, such as a bolt, to pass through the first inner hole 400 and the second inner hole to connect the shock pad and the base, making both the first inner hole 400 and the second inner hole oval holes can leave a certain margin between the connecting member and the inner walls of the first inner hole 400 and the second inner hole, making it easier for the connecting member to extend into the first inner hole 400 and the second inner hole and improving the assembly efficiency.

[0126] Optionally, both the first inner hole 400 and the second inner hole are circular holes. When using a connecting member, such as a bolt, to pass through the first inner hole 400 and the second inner hole to connect the shock pad and the base, making both the first inner hole 400 and the second inner hole circular holes can make the connection between the connecting member and the inner walls of the first inner hole 400 and the second inner hole closer, and thus the connection between the shock pad and the base is more reliable.

[0127] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
