Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

As shown in fig. 1 to 3, the vibration damping pad of the embodiment of the present application includes a pad body 1, the pad body 1 is cylindrical, preferably cylindrical, a through hole 11 is provided in the pad body 1 along an axial direction thereof, at least one of two end surfaces of the pad body 1 in the axial direction is provided with a first annular groove 12, the first annular groove 12 is circumferentially provided around the through hole 11, in other words, the pad body 1 has two end surfaces in the axial direction, one of the two end surfaces is provided with an annular groove, or both end surfaces are provided with annular grooves.

As shown in fig. 4, the vibration damping pad of the embodiment of the present application is mainly used for fixing an intercooling pipeline of a vehicle, and can be matched with a bracket 3 and a metal bushing 2 to fix the intercooling pipeline on a vehicle body, specifically, the metal bushing 2 includes a cylindrical part 21 and a connecting plate 22 connected to one end of the cylindrical part 21, a connecting column 23 is provided on the connecting plate 22, the connecting column 23 is inserted into a first annular groove 12 to connect the metal bushing 2 with a pad body 1, the metal bushing 2 and the pad body 1 are installed on the bracket 3, and the intercooling pipeline passes through a through hole 11 located in the pad body 1 to be fixed.

The damping pad of this application embodiment is through seting up first ring channel 12 on the terminal surface of filling up body 1 for the area of contact of metal bush 2 or other mountings and damping pad terminal surface reduces, and the rigidity of damping pad terminal surface reduces, and the increase of compliance has reduced the natural frequency of damping pad, thereby has increased the axial damping ability of damping pad.

The damping pad of this application embodiment keeps original design size unchangeable, under the unchangeable prerequisite of cost, has improved the ability that the damping pad reduced vibration, and then noise in the reduction car improves user's driving and takes experience.

In some embodiments, the outer peripheral wall of the pad body 1 is further provided with a second annular groove 13, the axis of the second annular groove 13 is collinear with the axis of the pad body 1, and the bottom of the second annular groove 13 is provided with a protrusion 14.

It can be understood that the arrangement of the protrusion 14 at the groove bottom of the second groove reduces the contact area between the bracket 3 and the pad body 1, and the protrusion 14 can be understood as being formed by continuously providing the groove at the groove bottom of the second groove, thereby reducing the rigidity of the outer peripheral surface of the damping pad, increasing the flexibility, and increasing the radial damping capacity of the damping pad.

In some embodiments, the first annular grooves 12 are plural, the plural first annular grooves 12 are arranged at intervals in the radial direction of the pad body 1, that is, the diameters of the plural first annular grooves 12 are different, and the first annular groove 12 with a larger diameter is wound around the circumferential side of the first annular groove 12 with a smaller diameter, whereby the number of the first annular grooves 12 is increased, the strength of the end face of the damping pad is weaker, and the damping pad becomes weaker, so that the axial damping capacity of the damping pad is further increased.

Similarly, second annular groove 13 is a plurality of, and a plurality of second annular grooves 13 are arranged along the axial interval of pad body 1, and second annular groove 13 mainly used and support 3 cooperation to with pad body 1 fixed mounting on support 3, the increase in number of second annular groove 13 can make the relation of connection between pad body 1 and the support 3 more stable, avoids pad body 1 to drop under the road conditions of jolting.

In some embodiments, the protrusions 14 are arranged in a plurality of numbers, and the protrusions 14 are arranged at intervals along the circumferential direction of the cushion body 1, so that the connection stability between the cushion body 1 and the bracket 3 is ensured, the cushion body 1 is prevented from shaking in the driving process of a vehicle, and the number and the structure of the protrusions 14 can be designed according to different vehicle types.

Alternatively, the cross section of the bulge 14 is in the shape of a gear tooth, the plurality of bulges 14 are arranged at intervals along the circumferential direction of the pad body 1, and the longitudinal cross section area of the bulge 14 is gradually reduced from inside to outside along the radial direction of the pad body 1, so that the cross section of the pad body 1 at the second annular groove 13 is in the shape of a gear, and the total contact area between the bulge 14 and the bracket 3 is small due to the smaller cross section area of the outer end of the bulge 14, and the vibration reduction effect is better.

Optionally, the cross-sectional shape of the protrusion 14 is trapezoidal, and the longitudinal cross-sectional area of the protrusion 14 gradually decreases from inside to outside along the radial direction of the pad body 1, the trapezoidal structure is similar to the gear tooth structure, except that the contact area between the trapezoidal protrusion 14 and the bracket 3 is larger, and the connection relationship between the protrusion 14 of the trapezoidal structure and the bracket 3 is more stable than that of the gear tooth structure.

Alternatively, the cross-sectional shape of the protrusion 14 is a sector, that is, the surface shape of the protrusion 14 is a circular arc surface, and a plurality of protrusions 14 are arranged at intervals along the circumferential direction of the pad body 1, so that the cross-sectional shape of the pad body 1 at the second annular groove 13 is a wave shape, and the protrusion 14 of this structure not only has a good damping effect, but also has a stable connection with the bracket 3.

In some embodiments, the cross-sectional shape of the cushion body 1 is circular or polygonal, such as quadrilateral, pentagonal, hexagonal, etc., in other words, the cushion body 1 may be cylindrical or square column, and the specific shape of the cushion body 1 is determined according to different vehicle types and structural designs.
