Description

Technical Field

[0001] The utility model belongs to a shock absorbing structure, in particular to a shock absorbing pad. Background Art

[0002] Shock-absorbing pads play a shock-absorbing role when used and are widely used in various fields. By adding a shock-absorbing pad between the two structures at the place where two structures cooperate, certain shock-absorbing and noise-reducing effects can be achieved. For example, application No. 201610099087.1 discloses a shock-absorbing pad and a motor. It can be seen from paragraph 54 of its specification that the inner wall of the through hole of the shock-absorbing pad is in close contact with the corresponding raised part of the motor shell through the through hole of the shock-absorbing pad to achieve a matching effect. However, when this type of shock-absorbing pad is in use, the vibration of the matching structure in the through hole is transmitted to the shock-absorbing pad, and then transmitted to the matching structure after the shock-absorbing effect of the shock-absorbing pad. The shock-absorbing effect is not particularly good and needs to be improved. Utility Model Content

[0003] The purpose of the utility model is to provide a shock-absorbing pad that can solve at least one of the above problems.

[0005] The beneficial effect of the utility model is that a shock-absorbing ring is provided in the mounting hole, so that when the mounting hole cooperates with the external structure, the shock-absorbing ring is tightly attached to the side wall of the external structure, and the inner wall of the entire mounting hole is prevented from being tightly attached to other structures, thereby greatly reducing the contact area between the mounting hole of the shock-absorbing pad and the external matching structure, thereby reducing the transmission of vibration, greatly reducing the vibration of the external structure, and achieving a good shock-absorbing effect.

[0006] In some embodiments, the mounting groove is located in the middle of the outer periphery of the body, and a plurality of convex strips are provided at the bottom of the mounting groove. Thus, by providing the convex strips, the contact area between the bottom of the mounting groove and the matching structure on the mounting groove can be reduced, and the matching structure on the mounting groove contacts the convex strips instead of the entire bottom of the mounting groove, thereby further reducing the transmission of vibration and playing a shock-absorbing role.

[0007] In some embodiments, there are multiple damping rings, thereby ensuring that the structures in the mounting hole can be matched stably.

[0008] In some embodiments, the body, the shock absorbing ring and the convex strip are an integrally formed structure, thereby facilitating the molding process of the entire body.

[0009] In some embodiments, the convex strips are arranged along the length direction of the body, thereby facilitating the arrangement of the convex strips and facilitating the arrangement of multiple convex strips on the periphery of the body.

[0010] In some embodiments, the top of the body is provided with a plurality of bosses, and the plurality of bosses are evenly distributed on the upper end surface of the body. Thus, by providing the bosses, the contact area between the top of the body and the external matching structure can be reduced, further achieving a shock-absorbing effect.

[0011] In some embodiments, an inclined surface is provided on the inner side of the boss, and the inclined surface is inclined toward one side of the mounting hole. Thus, by providing the inclined surface, it is convenient to play a guiding role when the external structure cooperates with the mounting hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] Reference Figure 1 to Figure 3 The shock-absorbing pad comprises a body 1, the body 1 is provided with a mounting hole 11, the mounting hole 11 runs through the upper and lower ends of the body 1, the outer periphery of the body 1 is provided with a mounting groove 12, the inner wall of the mounting hole 11 is provided with a shock-absorbing ring 13, and the inner diameter of the shock-absorbing ring 13 is smaller than the inner diameter of the mounting hole 11. The body 1 is a rubber part, which is the same material as the commonly used shock-absorbing pad.

[0017] The mounting groove 12 is formed around the entire periphery of the body 1, and the opening of the mounting groove 12 faces the outside of the body 1, so that the mounting groove 12 can be matched with the external structure. When the mounting groove 12 matches with other structures, the side walls of the mounting groove 12 are clamped on the external structure, and the bottom of the mounting groove 12 is pressed against the corresponding end surface of the external structure, so that the mounting groove 12 is firmly installed.

[0018] When in use, the shock-absorbing pad is installed and fixed at a corresponding position of one of the external structures (hereinafter referred to as the "first external structure") through the installation groove 12. Specifically, a corresponding through hole is opened on one of the external structures, and the body 1 is inserted into the through hole. The side wall of the installation groove 12 clamps the external structure, thereby realizing the installation of the body 1 on the first external structure. Subsequently, another external structure (hereinafter referred to as the "second external structure") extends into the installation hole 11 and cooperates with the installation hole 11, so that the shock-absorbing pad is located between the two external matching structures.

[0019] Since the shock absorbing ring 13 is provided, when the second external structure cooperates with the mounting hole 11, the second external structure is pressed against the inner wall of the shock absorbing ring 13 through the shock absorbing ring 13, which helps to reduce the contact area between the second external structure and the mounting hole 11, thereby reducing the vibration transmitted from the shock absorbing pad to the second external structure, or reducing the vibration transmitted from the second external structure to the shock absorbing pad, thereby playing a good shock absorbing role.

[0020] The mounting groove 12 is located in the middle of the outer periphery of the body 1, and a plurality of convex strips 14 are provided at the bottom of the mounting groove 12. The convex strips 14 are arranged along the length direction of the body 1. By providing a plurality of convex strips 14, when the first external structure cooperates with the mounting groove 12, the contact area between the first external structure and the bottom of the mounting groove 12 is reduced, and the first external structure will not contact the bottom of the entire mounting groove 12, but will act on the convex strips 14, thereby improving the shock absorption effect.

[0021] There are multiple damping rings 13, so that the external structure is pressed against the inner wall of the damping ring 13, thereby reducing the contact area between the external structure and the inner wall of the mounting hole.

[0022] The body 1, the shock absorbing ring 13 and the convex strip 14 are an integral injection-molded structure.

[0023] The top of the body 1 is provided with a plurality of bosses 15, which are evenly distributed on the upper end surface of the body 1. By providing the bosses 15, when the corresponding surface of the second external structure is pressed against the top of the shock-absorbing pad, it is pressed against the bosses 15, reducing the contact area with the top surface of the shock-absorbing pad, thereby improving the shock-absorbing effect. In actual use, the bottom end surface of the body 1 can also be formed with a plurality of bosses 15, which are evenly distributed on the lower end surface of the body 1, to further improve the shock-absorbing effect.

[0024] An inclined surface 151 is provided on the inner side of the boss 15 , and the inclined surface 151 is inclined toward the mounting hole 11 , that is, the inclined surface 151 can guide the matching rod / column and other structures inserted into the mounting hole, thereby facilitating assembly.

[0025] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
