[0033] Please refer to Figures 1 to 7 As shown, this application provides a buffer pad 2, which is suitable for being installed on a frame 1 to play a role in vibration damping and buffering in a fastening connection structure. The fastening connection structure includes various fastening connection methods such as bolts, buckles, riveting, etc. The buffer pad 2 includes an elastic main body portion 21 and a claw portion 22. The elastic main body portion 21 includes at least partially opposite two support end faces 211 and a circumferential side face located between the two support end faces 211. The claw portion 22 protrudes from the circumferential side face. The claw portion 22 is suitable for being connected with the frame 1 in a clamping manner, and the claw portion 22 is in contact with the frame 1 both in the radial direction and the axial direction of the buffer pad 2.

[0034] The buffer pad 2 provided by this application includes an elastic main body portion 21 and a claw portion 22. By connecting the claw portion 22 with the frame 1 in a clamping manner, the assembly is convenient, the assembly efficiency and installation accuracy are improved. The claw portion 22 is in contact with the frame 1 both in the radial direction and the axial direction of the buffer pad 2, increasing the overall structural rigidity of the buffer pad 2, enhancing the ability to withstand vibration and impact, and improving the vibration damping and buffering performance.

[0035] Embodiment 1

[0036] Please refer toFigures 1 to 4 As shown, it is a diagram of the first embodiment of the buffer pad 2 of the present application. In this embodiment, the buffer pad 2 is made of an elastic material, for example, it is a rubber pad. The buffer pad 2 is generally cylindrical in shape and has an axial direction and a radial direction. The axial direction is as shown by the L line in Figure 4 , and the radial direction is as shown by the R line in Figure 4 . When the buffer pad 2 is in use, it is mainly subjected to a squeezing force in the axial direction. When subjected to the squeezing force, the buffer pad 2 will not only be compressed and deformed along the axial direction but also expand and deform in the radial direction. The buffer pad 2 includes an elastic main body portion 21, a claw portion 22, and a positioning rib 23.

[0037] The elastic main body portion 21 is cylindrical in shape and has two opposite supporting end faces 211 and a circumferential side face located between the two supporting end faces 211. The two supporting end faces 211 are the force-bearing surfaces of the buffer pad 2 during use, that is, the buffer pad 2 is subjected to a squeezing force in the direction along the axis of the elastic main body portion 21 during use. The two supporting end faces 211 are the top and bottom surfaces of the cylinder, and they can be exactly opposite to each other or have a certain misalignment setting. The elastic main body portion 21 includes a through hole 210 that penetrates the two supporting end faces 211. In this embodiment, the through hole 210 is provided on the central axis of the elastic main body portion 21.

[0038] The claw portion 22 extends obliquely outward from the circumferential side face. The claw portion 22 extends from a position near the supporting end face 211 of the circumferential side face to the middle cross-section of the elastic main body portion 21, so that the claw portion 22 is an inclined annular body. The middle cross-section is as shown in Figure 4A plane perpendicular to the paper surface and marked as D in the figure. In this embodiment, there are two claw parts 22, and the two claw parts 22 are respectively arranged close to the two supporting end faces 211 and are symmetrically arranged with respect to the middle cross-section. By using two symmetrically arranged claw parts 22, there is no need to distinguish the assembly direction during use, and it can be assembled in any direction. Of course, in other embodiments, the claw part 22 can be set to only one; in some other embodiments, the claw part 22 can also be set to more than two. In this embodiment, the free end of the claw part 22 has a vertical contact surface 222 and a horizontal contact surface 221. The claw part 22 extends in a cantilever shape from the elastic main body part 21, and the end connected to the elastic main body part 21 is the connection end, and the end far from the elastic main body part 21 is the free end. In other words, the suspended end of the claw part 22, that is, the end not connected to the elastic main body part 21, is the free end. The vertical contact surface 222 realizes contact with the frame 1 in the radial direction of the buffer pad 2 to limit the radial movement of the buffer pad 2 and improve the installation accuracy; the horizontal contact surface 221 realizes contact with the frame 1 in the axial direction of the buffer pad 2 to effectively bear the force generated during vibration. By providing the vertical contact surface 222 and the horizontal contact surface 221 at the free end of the claw part 22, a stable support structure can be formed with the frame 1, enhancing the overall rigidity of the buffer pad 2 and improving the vibration reduction and buffering performance. It should be noted that the vertical contact surface 222 and the horizontal contact surface 221 should be understood that the contact surface is used to contact the frame 1 in the vertical or horizontal direction, and does not limit the shape and structure of the contact surface itself. For example, the vertical contact surface 222 and the horizontal contact surface 221 can be a plane with a certain area, or a corrugated, serrated or several convex dot-like structures, etc.

[0039] The positioning rib 23 protrudes from the circumferential side surface of the elastic main body part 21, and the positioning rib 23 extends horizontally outward along the radial direction from the circumferential side surface. In this embodiment, the positioning rib 23 is arranged on the middle cross-section of the elastic main body part 21, and the positioning rib 23 is located between the two claw parts 22. The positioning rib 23 and the hole position on the frame 1 for its corresponding installation are in clearance fit. During installation, the claw part 22 passes over the hole position, so that when the positioning rib 23 is engaged with the corresponding hole position, there is an obvious change in the damping feeling, which is convenient for confirming that the assembly is in place and at the same time reduces the risk of shortening the service life due to the distortion of the positioning rib 23. During use, through the cooperation between the positioning rib 23 and the frame 1, the influence of horizontal vibration on the whole can also be alleviated. A deformation accommodating cavity 24 is formed between the positioning rib 23 and the claw part 22. The deformation accommodating cavity 24 is similar in size to the claw part 22 to provide a storage space for the folded and deformed claw part 22 during extrusion installation, and to avoid damaging the rubber due to improper operation during extrusion installation and shortening the overall service life of the buffer pad 2.

[0040] Embodiment 2

[0041] See also Figure 5 , which is a diagram of the second embodiment of the buffer pad 2 of the present application. The main difference between this embodiment and the first embodiment is that the structure of the free end of the claw portion 22 is different.

[0042] In this embodiment, the free end of the claw portion 22 is configured as a circular arc contact surface suitable for simultaneously contacting two perpendicularly intersecting wall surfaces. The circular arc contact surface can also limit the buffer pad 2 in the radial and axial directions, and enhance the rigidity of the buffer pad 2 when it is subjected to force. Moreover, by changing the free end of the claw portion 22 from a sharp corner to a rounded corner, the contact area between the end sharp corner and the frame 1 can be reduced, which can reduce the requirements for dimensional accuracy and the difficulty of demoulding, thereby reducing costs. At the same time, the cavity formed by the contact between the end rounded corner of the claw portion 22 and the frame 1 can be used to store metal burrs and other debris, reducing the possibility of scratches on the surface of the rubber pad caused by burrs and other high-hardness impurities, resulting in failure.

[0043] The parts not described in this embodiment can be implemented with reference to the first embodiment and will not be described in detail here.

[0044] Embodiment 3

[0045] See also Figure 6 , which is a diagram of the third embodiment of the buffer pad 2 of the present application. The main difference between this embodiment and the first embodiment is that the free end of the claw portion 22 and the structure on the frame 1 that matches therewith are different.

[0046] In this embodiment, the free end of the claw portion is configured to be suitable for being accommodated in a groove provided on the frame, and the free end abuts against the wall forming the groove. Specifically, the free end of the claw portion 22 is configured as an arc contact surface, and an arc groove is provided on the frame 1, and the arc contact surface is accommodated in the arc groove provided on the frame 1. In this embodiment, by providing an arc groove on the frame 1 for the free end of the claw portion 22 to be embedded and fixed, the structural stability between the buffer pad 2 and the frame 1 can be increased, the overall rigidity can be improved, and the installation accuracy can be improved. In other embodiments, the groove is not limited to an arc shape, and it can also be a groove of other shapes. At the same time, the free end of the claw portion 22 is set to a shape that matches and abuts against the shape of the groove.

[0047] The parts not described in this embodiment can be implemented with reference to the first embodiment and will not be described in detail here.

[0048] Embodiment 4

[0049] See also Figure 7 , which is a diagram of the fourth embodiment of the buffer pad 2 of the present application. The main difference between this embodiment and the first embodiment is that the structure of the claw portion 22 is different.

[0050] In some of these embodiments, the jaw portion 22 is a plurality of non - continuous arc segments. That is, a number of notches 220 are evenly formed in the annular jaw portion 22 in the first embodiment to form the jaw portion 22 in this embodiment. On the premise that the overall strength of the buffer pad 2 meets the requirements, by providing a number of notches 220, the material can be saved and the cost can be reduced.

[0051] For the parts not described in this embodiment, reference may be made to the first embodiment, and details will not be repeated here.

[0052] The present application also provides a buffer assembly mechanism 100, including a frame 1, a fitting sleeve 3, and the buffer pad 2 as described in any of the above embodiments. Among them, the fitting sleeve 3 is inserted on the central axis of the elastic main body portion 21, the buffer pad 2 is clamped in the frame 1, and the elastic main body portion 21 and the jaw portion 22 are defined between the frame 1 and the fitting sleeve 3.

[0053] In some embodiments, the frame 1 includes a cylindrical tube portion 11, and a circular flange 12 is provided in the middle of the cylindrical tube portion 11. When the buffer pad 2 is assembled in the cylindrical tube portion 11, the two jaw portions 22 are correspondingly located in the cylindrical tube portion 11 on the upper and lower sides of the circular flange 12, and the positioning ribs 23 are correspondingly located in the circular flange 12. The fitting sleeve 3 includes a hollow column 31 and a gasket 32 provided at one end of the hollow column 31. The gasket 32 supports on a supporting end face 211 of the elastic main body portion 21. The hollow column 31 is inserted through the through - hole 210 of the buffer pad 2, and the hollow column 31 has a hollow hole 310 for a fastener to pass through. In one embodiment, the fitting sleeve 3 is a metal part. Through the cooperation between the supporting end face 211 and the gasket 32 of the fitting sleeve 3, when impacted, the impact force can be evenly applied to the supporting end face 211 of the buffer pad 2, and then the buffer pad 2 as a whole buffers the impact force. Its force is evenly distributed and it has a long service life.

[0054] During use, the buffer pad 2 is inserted into the cylindrical portion 11 of the frame 1, and the buffer pad 2 is limited within the cylindrical portion 11 of the frame 1 by the claw portion 22; the fitting sleeve 3 is inserted into the through hole 210 of the buffer pad 2, and the gasket 32 included in the fitting sleeve 3 abuts against one support end face 211 of the buffer pad 2; fasteners such as bolts pass through the hollow column 31 of the fitting sleeve 3 and are fixedly connected to the connecting component, thereby realizing the fixed connection between the connecting component and the frame 1. During vibration, due to the buffering effect of the buffer pad 2, the impact force between the connecting component and the frame 1 can be reduced. In one embodiment, the buffer assembly mechanism 100 is used for connecting the oil cooler in the vehicle to the engine frame 1, that is, the frame 1 is the engine frame 1, and the connecting component is the oil cooler; of course, in other embodiments, the frame 1 and the connecting component thereon are not limited thereto.

[0055] From the description of the specific embodiments above, it can be seen that the buffer pad 2 provided in the present application includes an elastic main body portion 21 and a claw portion 22. The elastic main body portion 21 includes two opposite support end faces 211 and a peripheral side surface located between the two support end faces 211. The claw portion 22 protrudes from the peripheral side surface. The claw portion 22 is adapted to be snap-connected to the frame 1, and the claw portion 22 contacts the frame 1 both in the radial direction and the axial direction of the buffer pad 2; the buffer pad 2 provided in the present application is snap-connected to the frame 1 through the claw portion 22, which is convenient for assembly, improves the assembly efficiency and installation accuracy. The claw portion 22 contacts the frame 1 both in the radial direction and the axial direction of the buffer pad 2, increasing the overall structural rigidity of the buffer pad 2, enhancing the ability to withstand vibration and impact, and improving the vibration damping and buffering performance.

[0056] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0057] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
