Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Example

[0024] This utility model provides a lightweight rubber shock absorber sleeve for electric vehicles with a hollow honeycomb structure. Please refer to [link / reference]. Figure 1-4 It includes an upper rubber damping sleeve 1 and a lower rubber damping sleeve 4. The lower rubber damping sleeve 4 is located below the upper rubber damping sleeve 1, and the lower rubber damping sleeve 4 and the upper rubber damping sleeve 1 are fixed together by bolts. The lower rubber damping sleeve 4 has a first honeycomb hole 41.

[0025] The bottom of the upper part 1 of the rubber shock absorber has an integral rubber reinforcing plate 2, and a metal support ring 3 is bonded to the bottom of the rubber reinforcing plate 2. A metal internal thread tube 5 is fixedly installed on the lower part 4 of the rubber shock absorber. The rubber reinforcing plate 2, the metal support ring 3 and the metal internal thread tube 5 are all fixed together by bolts.

[0026] The rubber reinforcing plate 2 has a nut groove 21 and a first through hole 22, and the metal support ring 3 has a second through hole 31. The bolts that fix the rubber reinforcing plate 2, the metal support ring 3 and the metal internal threaded tube 5 pass through the nut groove 21, the first through hole 22 and the second through hole 31, and the bolts that fix the rubber reinforcing plate 2, the metal support ring 3 and the metal internal threaded tube 5 are threadedly connected to the inner wall of the metal internal threaded tube 5. The nuts of the bolts that fix the rubber reinforcing plate 2, the metal support ring 3 and the metal internal threaded tube 5 are located in the nut groove 21.

[0027] The upper part 1 of the rubber shock absorber sleeve has a first vertical hole 11, the diameter of which is the same as the wall thickness of the upper part 1. The connection between the metal support ring 3 and the metal internally threaded tube 5 makes the connection between the upper part 1 and the lower part 4 of the rubber shock absorber sleeve more secure. When the upper part 1 and the lower part 4 of the rubber shock absorber sleeve are subjected to downward pressure, the presence of the first vertical hole 11 makes the upper part 1 of the rubber shock absorber sleeve more easily deformable, thus achieving a better shock absorption effect. Similarly, the presence of the first honeycomb hole 41 makes the lower part 4 of the rubber shock absorber sleeve more easily deformable, thus achieving a better shock absorption effect. Furthermore, the presence of the first vertical hole 11 and the first honeycomb hole 41 makes the upper part 1 and the lower part 4 of the rubber shock absorber sleeve lighter. Example

[0028] See attached document Figure 5 Unlike Embodiment 1, the upper part 1 of the rubber shock absorber sleeve has a second vertical hole 12 and a horizontal hole 13. The horizontal hole 13 is located on both sides of the second vertical hole 12 and is connected to the second vertical hole 12. In this case, the diameter of the second vertical hole 12 is half the wall thickness of the upper part 1 of the rubber shock absorber sleeve. Due to the presence of the horizontal hole 13 in the second vertical hole 12, the upper part 1 of the rubber shock absorber sleeve is more easily deformed, thus achieving a better shock absorption effect. Similarly, due to the presence of the first honeycomb hole 41, the lower part 4 of the rubber shock absorber sleeve is more easily deformed, thus achieving a better shock absorption effect. Furthermore, the presence of the first vertical hole 11 and the first honeycomb hole 41 makes the upper part 1 and the lower part 4 of the rubber shock absorber sleeve lighter. Example

[0029] See attached document Figure 6 Unlike Embodiment 1, the upper part 1 of the rubber shock absorber sleeve has a second honeycomb hole 14. Due to the presence of the second honeycomb hole 14, the upper part 1 of the rubber shock absorber sleeve is more easily deformed, thereby achieving a better shock absorption effect; similarly, due to the presence of the first honeycomb hole 41, the lower part 4 of the rubber shock absorber sleeve is more easily deformed, thereby achieving a better shock absorption effect; and the presence of the first vertical hole 11 and the first honeycomb hole 41 makes the upper part 1 and the lower part 4 of the rubber shock absorber sleeve lighter.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
