Description

Technical Field

[0001] This utility model relates to the field of automotive door interior panel technology, and in particular to a high-strength automotive door interior panel. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, the new energy vehicle market is developing rapidly. As an important component of new energy vehicles, door interior panels not only need to meet aesthetic and comfort requirements, but also need to be lightweight, environmentally friendly, and durable. Existing interior panels mostly use ordinary plastics or composite materials, which have problems such as insufficient impact resistance and easy deformation, which may affect the safety of occupants in side collisions.

[0003] As an important component of car doors, door armrests are easily worn down during long-term use. If the armrests are not protected, their service life will be shortened. Therefore, it is necessary to design a high-strength automotive door interior panel. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength automotive door interior panel to address the shortcomings of existing interior panels, such as insufficient impact resistance and easy deformation.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-strength automotive door interior panel, including an interior panel body;

[0006] A decorative piece is fixed to one side of the top of the interior panel body. An armrest is installed on the outer wall of the interior panel body below the decorative piece. A protective structure is fixed to the outside of the armrest. The protective structure includes an adhesive layer, a first protective layer, and a second protective layer. The adhesive layer is fixed to the outside of the armrest. The first protective layer is fixed to the outside of the adhesive layer. The second protective layer is fixed to the outside of the first protective layer.

[0007] The interior panel above the armrest has a central piece inside, and the interior panel below the armrest has a map pocket inside.

[0008] A speaker cover is provided on one side of the bottom of the interior panel body, and a mid-range speaker is installed on the inner wall of the interior panel body near the map pocket.

[0009] Furthermore, the interior panel body is made of carbon fiber reinforced plastic.

[0010] Furthermore, the bottom of the armrest is equipped with a hidden handle and ambient lighting.

[0011] Furthermore, an electroplated logo is provided on the outer side of the speaker cover.

[0012] Furthermore, the first protective layer is a PVC layer.

[0013] Furthermore, the second protective layer is a PU layer.

[0014] The advantages of the high-strength automotive door interior panel provided by this utility model are as follows:

[0015] By setting up a protective structure, the first protective layer is a PVC layer, which can provide rigid support and wear resistance for the armrest and resist daily scratches. The second protective layer is a PU layer, which is fixed to the outside of the first protective layer. This can improve the surface flexibility of the outside of the first protective layer, absorb collision energy, and reduce the impact transmitted to the interior of the interior panel body. This makes the device have the function of easy wear-resistant buffering, and improves the convenience and applicability of the high-strength automotive door interior panel in use.

[0016] By incorporating an interior panel body made of carbon fiber reinforced plastic, which has high tensile strength and low density, a perfect combination of lightweight and high load-bearing capacity can be achieved. This device increases the strength of the car door, improving the durability and safety of the high-strength automotive door interior panel during use. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1-5 The present invention provides a high-strength automotive door interior panel, including an interior panel body 1.

[0025] Reference Figures 1-5 A decorative piece 3 is fixed to one side of the top of the interior panel body 1. An armrest 2 is installed on the outer wall of the interior panel body 1 below the decorative piece 3. A protective structure 8 is fixed to the outside of the armrest 2. The protective structure 8 includes an adhesive layer 81, a first protective layer 82, and a second protective layer 83. The adhesive layer 81 is fixed to the outside of the armrest 2. The first protective layer 82 is fixed to the outside of the adhesive layer 81. The second protective layer 83 is fixed to the outside of the first protective layer 82. A middle piece 4 is provided inside the interior panel body 1 above the armrest 2. A map pocket 7 is opened inside the interior panel body 1 below the armrest 2. A speaker cover 6 is provided on one side of the bottom of the interior panel body 1. A mid-range speaker 5 is installed on the inner wall of the interior panel body 1 near the map pocket 7. The material of the interior panel body 1 is carbon fiber reinforced plastic. A hidden handle and ambient light are installed at the bottom of the armrest 2. An electroplated logo is provided on the outside of the speaker cover 6. The first protective layer 82 is a PVC layer, and the second protective layer 83 is a PU layer.

[0026] The external force first acts on the second protective layer 83. When the second protective layer 83 deforms under the force, the elastic deformation can absorb the initial impact energy. The remaining energy is dispersed through the first protective layer 82, ensuring that the stress is evenly transmitted to the interior panel body 1 and avoiding local stress concentration. The interior panel body 1 has high tensile strength and light weight, and has the advantages of high strength and lightweight.

[0027] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
