Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts, and in particular to automotive armrest structures. Background Technology
[0002] Currently, rotating armrests are typically installed in the rear seats of cars for the convenience of rear passengers. To reduce the vibration amplitude of the armrest structure and increase passenger awareness, damping components are usually installed at the rotating position of the armrest structure. The damping components can increase the resistance of the armrest structure when opening or closing, thereby preventing the armrest structure from falling off due to vibration during vehicle operation and avoiding damage to the armrest structure. However, due to its thickness, the existing damping structure is exposed in the gap between the armrest structure and the armrest frame, which is not aesthetically pleasing. Moreover, if used for a long time, it will cause the damping to deform, resulting in damping interference with the movement of the armrest cover.
[0003] The technical problem to be solved by this application is: how to reduce the problem of exposed damping and improve aesthetics. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a handrail damping structure.
[0005] The technical solution adopted by this utility model is as follows: a handrail damping structure, including a handrail bracket, a handrail assembly, and a damping component. The damping component is disposed between the handrail bracket and the handrail assembly. The damping component includes a damping cover and an elastic pad. The damping cover has a connecting hole and a rotating shaft. The rotating shaft is limited to rotating within the connecting hole. The diameter of the connecting hole is larger than the diameter of the rotating shaft. The elastic pad is disposed on the damping cover. The bottom end of the elastic pad abuts against the outer wall of the rotating shaft. The damping cover has a sliding track above the elastic pad. The handrail bracket is connected to the handrail assembly through the rotating shaft. The handrail bracket is fixedly provided with an interference pin that slides on the sliding track. The distance between the interference pin and the rotating shaft is smaller than the distance from each point on the sliding track to the rotating shaft.
[0006] In some implementations, the bottom end of the elastic pad is curved.
[0007] In some implementations, the sliding trajectory has a limiting endpoint at at least one end, and the interference pin is at the limiting endpoint when the handrail assembly rotates to the moving end.
[0008] In some embodiments, one end of the rotating shaft is rotatably fixedly connected to the handrail assembly, and the other end is rotatably connected to the handrail bracket via a step bolt, with a washer provided between the step bolt and the handrail bracket.
[0009] In some embodiments, the damping cover has a guide limiting protrusion on the side near the handrail bracket, and the guide limiting protrusion abuts against the side wall of the handrail bracket.
[0010] In some implementations, the damping cover is made of plastic.
[0011] The beneficial effects of this utility model are as follows:
[0012] This handrail damping structure reduces the thickness of the damping component in the Y direction by modifying its structure, thereby reducing the exposed portion of the damping component. In the future, the color of the damping component can be matched with the surrounding components to further improve the appearance, hide the damping component as much as possible, improve the passenger's perceived quality, and enhance the overall aesthetics of the handrail structure.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1 This utility model provides a technical solution: a handrail damping structure, including a handrail cover 1, a handrail bracket 2, a handrail assembly 3 and a damping component 4. The damping component 4 is disposed between the handrail bracket 2 and the handrail assembly 3. The handrail cover 1 and the handrail bracket 2 are fixedly connected, and the handrail bracket 2 and the handrail assembly 3 are rotatably connected.
[0021] Please see Figures 3-5 The damping assembly 4 includes a damping cover 41 and an elastic pad 42. In this embodiment, the damping cover 41 is made of plastic, and the elastic pad 42 is made of a material with a certain degree of elasticity. The damping cover 41 has a connecting hole 43 and a rotating shaft 44. The rotating shaft 44 is limited to rotating within the connecting hole 43. The diameter of the connecting hole 43 is larger than the diameter of the rotating shaft 44. The elastic pad 42 is disposed inside the damping cover 41. The elastic pad 42 is configured as an inverted "T" shape and is disposed above the connecting hole 43. The top of the elastic pad 42 is aligned with the top of the connecting hole 43. The damping cover 41 is snap-fit connected, with its bottom end set in an arc shape and abutting against the outer wall of the rotating shaft 44. The arc-shaped bottom end of the elastic pad 42 can wrap around the rotating shaft 44 in a small area, thereby applying pressure to the rotating shaft 44 in multiple directions while preventing the rotating shaft 44 from detaching from the connection between the rotating shaft 44 and the elastic pad 42. The rotating shaft 44 is pressed by the elastic pad 42 against the bottom of the connecting hole 43. The damping cover 41 has a sliding track 411 above the elastic pad 42, and the two ends of the sliding track 411 are respectively provided with limiting endpoints 412. The elastic pad 42 is located on the side of the damping cover 41 near the handrail assembly 3 and is not exposed, which can reduce the overall thickness of the damping assembly 4 and improve aesthetics. One end of the rotating shaft 44 is rotatably fixedly connected to the handrail assembly 3, and the other end is rotatably connected to the handrail bracket 2 through the step bolt 21. One end of the rotating shaft 44 is fixedly connected to the step bolt 21. A washer is provided between the step bolt 21 and the handrail bracket 2. The washer can prevent wear on the step bolt 21 or the handrail bracket 2 when there is a relative position between the step bolt 21 and the handrail bracket 2. The damping cover 41 has a guide limiting protrusion 413 on the side near the handrail bracket 2. The guide limiting protrusion 413 abuts against the side wall of the handrail bracket 2. Since damping components 4 are provided on both sides of the handrail assembly 3, the guide limiting protrusion 413 makes the damping cover 41 fit tightly against the corresponding handrail bracket 2, and the two remain in a fixed position.
[0022] Please see Figure 2 The handrail bracket 2 is fixedly provided with an interference pin 22. The interference pin 22 rotates around the rotation axis 44. When the handrail assembly 3 is opened or closed, the interference pin 22 slides on the sliding track 411. When the handrail assembly 3 reaches the end of the movement, the interference pin 22 will enter the limit end point 412. When the interference pin 22 is at the limit end point 412, the distance between the interference pin 22 and the rotation axis 44 is less than the distance from each point of the sliding track 411 to the rotation axis 44. Therefore, when the interference pin 22 leaves the limit end point 412 and slides on the sliding track 411, the interference pin 22 will compress the elastic pad 42, shortening the distance between each point of the sliding track 411 and the rotation axis 44, so that the interference pin 22 can slide on the sliding track 411. The interference pin 22 and the damping cover 41 generate motion friction, thereby forming a damping effect.
[0023] Because the damping component 4 is relatively thin, the handrail cover 1 is snapped onto the handrail bracket 2, which can completely cover the handrail bracket 2. Furthermore, the damping cover 41 is uniformly colored to match the handrail cover 1, thereby improving the perceived quality.
[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
