A noise reduction structure for the sub-dashboard armrest

Abstract

This utility model provides a noise-reducing structure for a sub-dashboard armrest. The upper armrest cover is made using a wrapping process, and the upper armrest cover and the lower armrest cover are welded together using a hot plate. Rubber buffer pins are arranged on the armrest box frame. The buffer pins pass through the buffer pin mounting holes on the armrest box frame through their own snap-fit ​​structure (slot) and are then connected to the armrest box frame. When the armrest is fully opened, the upper armrest cover contacts the noise-reducing protrusions on the rubber buffer pins. The contact position is a soft contact and a point contact, which simultaneously achieves the functions of limiting movement and eliminating noise. The rubber buffer pins are arranged inside the armrest box frame, which does not affect the aesthetic appearance. The structure is compact and occupies little space. It eliminates noise and improves cabin comfort.

Description

Technical Field

[0001] This utility model belongs to the field of automotive interior technology, and in particular relates to a noise prevention structure for the sub-dashboard armrest. Background Technology

[0002] See appendix Figure 1 and Figure 2 In the existing technology, Figure 1 This is a diagram showing the handrail in the closed position. Figure 2 This is a schematic diagram of the armrest in the open state. The upper and lower covers of the armrest are welded using hot plates. The limiting mechanism for the armrest in the sub-dashboard is as follows: a limiting rib structure is arranged on the armrest box frame. When the armrest is opened, the limiting structure on the lower cover rotates via a pivot. When the armrest is opened to its maximum position, the limiting structure on the lower cover contacts and impacts the limiting rib on the armrest box frame and stops moving, thus completing the opening of the armrest.

[0003] The existing technology has the following drawbacks: due to the limitations of the molding materials and processes, both the lower cover of the armrest and the frame of the armrest box are made of plastic. When the armrest box is fully opened, the inner panel of the armrest contacts the limiting structure and causes an impact, which affects comfort. Therefore, this utility model proposes an anti-noise structure for the sub-dashboard armrest to solve the above problems. Utility Model Content

[0023] Example:

[0024] Please see Figures 3 to 4 This utility model provides a technical solution: a noise-proof structure for a sub-dashboard armrest, including an armrest box frame 1, an upper armrest cover 2, a limiting mechanism 3, and a lower armrest cover 4; the upper armrest cover 2 and the lower armrest cover 4 are welded by hot plate, the limiting mechanism 3 is a rubber buffer nail, the armrest box frame 1 is provided with a buffer nail mounting hole 5, the rubber buffer nail is engaged with the buffer nail mounting hole 5, the impact surface of the rubber buffer nail is provided with a noise-proof protrusion 6, the lower armrest cover 4 is provided with a lower cover plate limiting surface 7, when the armrest is opened, the lower cover plate limiting surface 7 contacts the noise-proof protrusion 6.

[0025] For further details, please refer to Figure 3 Rubber buffer pins are installed inside the armrest box frame 1.

[0026] Furthermore, the anti-noise protrusion 6 is integrally molded with the rubber buffer pin.

[0027] For further details, please refer to Figure 3 The rubber buffer nail has a slot, which engages with the buffer nail mounting hole 5.

[0028] In this embodiment, the armrest cover 2 adopts a wrapping process, and the armrest cover 2 and the armrest bottom cover 4 are welded by hot plate. Rubber buffer nails are arranged on the armrest box frame 1. The buffer nails pass through the buffer nail mounting holes 5 on the armrest box frame 1 through their own snap-fit ​​structure (slot) and are then connected to the armrest box frame 1. When the armrest is fully opened, the armrest cover 2 contacts the anti-noise protrusions 6 on the rubber buffer nails. The contact position is soft and point contact, which simultaneously achieves the functions of limiting movement and eliminating noise. The rubber buffer nails are arranged inside the armrest box frame 1, which does not affect the aesthetic appearance. The structure is compact and occupies little space. It eliminates noise and improves the comfort of the cabin.

[0029] Comparative Example (Prior Art):

[0030] Please see Figures 1 to 2 The existing anti-noise structure for the sub-instrument armrest includes an armrest box frame 1, an upper armrest cover 2, a limiting mechanism 3, and a lower armrest cover 4. The upper armrest cover 2 and the lower armrest cover 4 are welded by hot plate, and the limiting mechanism 3 is a limiting rib. The limiting form of the sub-instrument armrest is as follows: a limiting rib is arranged on the armrest box frame 1. When the armrest is opened, the limiting structure on the lower armrest cover 4 rotates through a rotating shaft. When the armrest is opened to the maximum position, the limiting structure on the lower armrest cover 4 contacts and impacts the limiting rib on the armrest box frame 1 and stops moving. At the same time, the armrest is opened.

[0031] The disadvantage is that, due to the limitations of the molding materials and processes, both the lower cover 4 of the armrest and the frame 1 of the armrest box are made of plastic. When the armrest box is fully opened, the inner panel of the armrest contacts the limiting structure and causes an impact in an abnormal direction, which affects comfort.

[0032] Compared with the comparative example: When the armrest is fully opened, the upper cover 2 of the armrest contacts the anti-noise protrusions 6 on the rubber buffer nail. The contact position is soft contact and point contact, which simultaneously achieves the functions of limiting and eliminating noise; the rubber buffer nail is arranged inside the armrest box frame 1, which does not affect the aesthetic appearance; the structure is compact and occupies little space; it eliminates noise and improves the comfort of the cabin.

[0033] The working principle and usage process of this utility model are as follows: The armrest cover 2 adopts a wrapping process, and the armrest cover 2 and the armrest bottom cover 4 are welded by hot plate; rubber buffer nails are arranged on the armrest box frame 1, and the buffer nails pass through the buffer nail mounting holes 5 on the armrest box frame 1 through their own snap-fit ​​structure (slot) and then connect to the armrest box frame 1; when the armrest is fully opened, the armrest cover 2 contacts the anti-noise protrusions 6 on the rubber buffer nails. The contact position is a soft contact and a point contact, which simultaneously achieves the functions of limiting and eliminating noise; the rubber buffer nails are arranged inside the armrest box frame 1, which does not affect the aesthetic appearance; the structure is compact and occupies little space; it eliminates noise and improves the comfort of the cabin.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
