Description

Technical Field

[0001] This utility model relates to the field of composite material technology, and in particular to a composite material exterior trim sandwich reinforcement skeleton structure. Background Technology

[0002] In the current industrial manufacturing field, composite material exterior parts are widely used in many industries such as automobiles, aerospace, and construction due to their advantages such as light weight, high strength, and good corrosion resistance.

[0003] During use, decorative elements often need to withstand certain external impacts and other forces. However, the core reinforcement skeleton of composite material exterior decorative elements is often dispersed in the center of the element. This unreasonable placement causes the edges and other parts of the element to lack effective support, making them prone to deformation during collisions or installation. At the same time, if the center is subjected to too much force, the stress cannot be effectively distributed, leading to deformation and damage at the stress points.

[0004] Therefore, we provide a composite material exterior trim sandwich reinforcement skeleton structure. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0024] Example: A composite material exterior trim sandwich reinforcement skeleton structure, such as Figures 1-4 As shown, it includes two symmetrically distributed composite panels 1, a sandwich panel 2 is provided between the two composite panels 1, and a skeleton assembly 3 is inlaid on the outside of the sandwich panel 2;

[0025] The skeleton component 3 consists of an edge skeleton 301, a connecting transition skeleton 302, and a central skeleton 303.

[0026] The adjacent two sides of the two composite panels 1 are tightly fitted with the opposite two sides of the sandwich panel 2, and the outer end surface of the skeleton assembly 3 is located on the same vertical plane as the opposite two sides of the sandwich panel 2.

[0027] The edge frame 301 is arranged in a square shape. There are two edge frames 301, which are located on the corresponding sides of the sandwich panel 2.

[0028] The central skeleton 303 is evenly distributed on the opposite two sides of the sandwich panel 2. The central skeleton 303 is located between two edge skeletons 301. There are several central skeletons 303. Several central skeletons 303 located on one side of the sandwich panel 2 are linearly and equidistantly distributed on the same vertical plane. The central skeleton 303 has a wavy shape.

[0029] One end surface of the connecting transition skeleton 302 is fixedly connected to the inner end surface of the edge skeleton 301, and the other end surface of the edge skeleton 301 is fixedly connected to one end of the central skeleton 303.

[0030] Because the edges of the composite panel 1 and the sandwich panel 2 are prone to deformation due to impacts and other external factors, edge skeletons 301 are provided on corresponding sides of the sandwich panel 2 to strengthen the edges of the composite panel 1 and the sandwich panel 2, preventing impact deformation. The connecting transition skeleton 302 acts as a transition between the edge skeleton 301 and the central skeleton 303, preventing the connection point from shrinking and causing excessive stress concentration leading to breakage. Furthermore, the connecting transition skeleton 302 forms a complete unit between the edge skeleton 301 and the central skeleton 303, ensuring that external forces are transmitted across the entire surface of the skeleton assembly 3. Under the action of 3, the impact from the surface can be buffered, and most of the composite board 1 and sandwich board 2 can be protected. Through the wave-shaped setting of the central skeleton 303, the external impact force can be effectively buffered and the impact force can be distributed to the entire skeleton assembly 3. The edge skeleton 301 protects the edge of the ornament, and the central skeleton 303 protects the surface of the ornament. With the connection of the connecting transition skeleton 302, the edge skeleton 301, the connecting transition skeleton 302 and the central skeleton 303 form a complete whole. The skeleton assembly 3 can protect the entire ornament, making the stress of the ornament more evenly distributed, avoiding the problem of stress concentration at a certain point, which can lead to deformation caused by excessive stress in some parts of the ornament, and further improving the stability of the composite material ornament during use.

[0031] like Figures 1-4 As shown, several protrusions 4 are installed on the adjacent two sides of the two composite plates 1. The protrusions 4 are evenly distributed and are triangular in shape. The outer surface of the protrusions 4 is equipped with serrated blocks 5.

[0032] The sandwich panel 2 has grooves 6 on both sides, and protrusions 4 are inserted into the grooves 6. The outer surface of the protrusions 4 is in contact with the inner wall of the grooves 6. The inner wall of the grooves 6 has serrated grooves 7, and serrated blocks 5 are inserted into the serrated grooves 7. The outer surface of the serrated blocks 5 is in contact with the inner wall of the serrated grooves 7.

[0033] To improve the connection strength between composite panel 1 and sandwich panel 2 and avoid delamination, a locking structure is formed by aligning and inserting the protrusions 4 and serrated blocks 5 of composite panel 1 with the grooves 6 and serrated slots 7 on sandwich panel 2. Due to the stability of triangles, the connection between the protrusions 4 and grooves 6 limits the connection between composite panel 1 and sandwich panel 2, preventing horizontal sliding. Simultaneously, the engagement of serrated blocks 5 and serrated slots 7 further increases the friction between composite panel 1 and sandwich panel 2, preventing separation. The insertion of protrusions 4 and grooves 6, and the connection of serrated blocks 5 and serrated slots 7, further enhance the connection strength between composite panel 1 and sandwich panel 2, ensuring the stability of the connection and preventing separation, thus further guaranteeing the stability of the frame assembly 3 during operation.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
