[0015] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar symbols represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0016] As Figure 1 shown, a highly durable rubber ear proposed in this embodiment includes a metal skeleton 1 and a rubber body 2. The metal skeleton 1 is provided with a mounting hole for assembling the rubber body 2. The rubber body 2 is installed on the inner peripheral surface of the mounting hole. A hook hole 3 is provided in the middle of the rubber body 2. A first buffer hole 4 and a second buffer hole 5 are respectively formed in the rubber body 2 above and below the hook hole 3. The side edge contours of the first buffer hole 4 and the second buffer hole 5 (set as approximate arcs, the first buffer hole 4 bends towards the hook hole 2 side, and the second buffer hole 5 bends slightly away from the hook hole) away from the hook hole 3 are set as wavy.

[0017] It should be noted that reinforcing ribs 8 are provided on both sides of the hook hole 3, which can increase the strength of the rubber body 2 and prevent serious deformation and damage of the hook hole 3.

[0018] In this way, by assembling the rubber body 2 into the metal skeleton 1, the durability performance of the ear is improved. At the same time, the outer contours of the first buffer hole 4 and the second buffer hole 5 formed in the rubber body 2 are wavy, having better buffer effect, noise reduction effect and shock absorption performance.

[0019] Furthermore, an annular lining sleeve 6 is provided between the rubber body 2 and the mounting hole. The annular lining sleeve 6 is installed on the inner peripheral surface of the mounting hole. Further, the annular lining sleeve 6 and the rubber body 2 are integrally vulcanized. In this way, the annular lining sleeve 6 and the rubber body 2 can be integrally vulcanized first, and then the whole is assembled on the inner peripheral surface of the mounting hole of the metal skeleton 1, increasing the versatility of the product. According to different installation environments, the metal skeleton 1 can be changed for adaptive installation.

[0020] Among them, the rubber body 2 is made of a special high-strength and high tear-resistant silicone rubber and adopts a high-temperature rapid vulcanization process.

[0021] In this embodiment, weight-reducing holes 7 are provided on the metal skeleton 1. Specifically, there are two weight-reducing holes 7, which are respectively located on both sides of the upper part of the mounting hole, and can reduce the weight of the metal skeleton 1, meeting the requirements of lightweight design.

[0022] It should be noted that the material of the metal skeleton 1 is set as A380 cast aluminum material, which has good casting performance, airtight performance, high mechanical properties, wear resistance, stable size and volume, etc.
