Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a support structure for the inner lining of an automotive fender. Background Technology

[0002] The car fender is a key component mounted on the side of the vehicle and decorates the chassis. While fenders are typically removable, they are easily damaged, especially after a major impact. Often, fenders are torn and cannot be repaired through sheet metal work, requiring replacement, which is costly. Most existing car fenders are single-layered, making them relatively weak and prone to severe deformation in a collision. Therefore, we propose an internal support structure for the car fender to address these issues. Utility Model Content

[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] like Figure 1-3 As shown:

[0025] A car fender liner support structure includes a frame body 101 disposed on one side of the fender, the frame body 101 being welded to the contour of one side of the fender.

[0026] The first reinforcing rib 104 is provided in multiple sets and is located inside the frame body 101. The two ends of the first reinforcing rib 104 are welded and fixed to the frame body 101 respectively.

[0027] The two ends of the second reinforcing rib 105 are welded and fixed to the adjacent first reinforcing rib 104 respectively;

[0028] Both the first reinforcing rib 104 and the second reinforcing rib 105 are welded and fixed to the leaf plate;

[0029] Multiple sets of connecting pieces 102 are provided and are distributed at equal intervals according to the outline of the frame body 101. The connecting pieces 102 are welded to the surface of the frame body 101, and mounting holes 103 are provided on the connecting pieces 102.

[0030] The frame body 101, the first reinforcing rib 104, and the second reinforcing rib 105 form a filling cavity together;

[0031] The inner liner 109 is located in the filling cavity, and one side of the inner liner 109 is bonded and fixed to the leaf plate.

[0032] In this implementation scheme: the frame body 101 serves as the basic support structure, providing a stable support platform for the entire fender liner. The frame body 101 is welded to one side profile of the fender, ensuring that it forms a solid whole with the fender, thereby providing strong support.

[0033] The first reinforcing rib 104 is set inside the frame body 101 to enhance the overall structural strength. The first reinforcing rib 104 is fixed to the frame body 101 by welding, together forming a stable internal support network.

[0034] The second reinforcing rib 105 is connected between the adjacent first reinforcing ribs 104, further enhancing the stability and bending resistance of the overall structure;

[0035] The connecting pieces 102 are evenly distributed according to the outline of the frame body 101 and have mounting holes 103 on them. These connecting pieces 102 are welded to the surface of the frame body 101, which not only further strengthens the structure, but also provides fixing points for the subsequent installation of the leaf plates.

[0036] The inner liner 109 adopts a honeycomb panel structure, which is made by firmly bonding two thinner panels to both sides of a thicker honeycomb core material. This honeycomb panel is bonded and fixed to the blade, and due to its unique geometry, it provides the blade with high strength and rigidity.

[0037] This solution significantly improves the overall strength and impact resistance of the fender by setting up the frame body 101, the first reinforcing rib 104, and the second reinforcing rib 105. The tight integration of the first reinforcing rib 104 and the second reinforcing rib 105 with the frame body 101 forms a robust support network that can effectively disperse and absorb impact forces from the outside, reducing fender tearing and deformation caused by impacts. At the same time, with the cooperation of the inner liner 109, the strength and rigidity of the fender are further enhanced, ensuring that the fender can maintain a good shape even under large impacts, avoiding serious deformation, thereby effectively protecting the safety of passengers inside the vehicle.

[0038] It should be noted that the frame body 101, the first reinforcing rib 104, and the second reinforcing rib 105 are all made of steel. These components have high strength, good durability, and a certain degree of toughness, making them very suitable for applications that need to withstand large loads and impacts.

[0039] Furthermore;

[0040] In an optional embodiment, a cushioning cotton 108 is fixed to the other side of the lining 109. The edge of the cushioning cotton 108 is fixed to the frame body 101, the first reinforcing rib 104 and the second reinforcing rib 105 respectively, or only to the frame body 101 and the first reinforcing rib 104 respectively.

[0041] In this embodiment, the cushioning cotton 108 is fixed to the other side of the inner liner 109, and its edge is fixed to the frame body 101, the first reinforcing rib 104 and the second reinforcing rib 105 respectively, or only fixed to the frame body 101 and the first reinforcing rib 104. This design increases the connection strength of the cushioning cotton 108. The cushioning cotton 108 is usually made of rubber or foam material. It not only provides a certain support for the fender, but also effectively prevents the fender from deforming excessively when it is impacted.

[0042] Furthermore;

[0043] In an optional embodiment, a sound insulation board 107 is fixedly installed on one side of the cushioning cotton 108. The edge side of the sound insulation board 107 is fixed to the frame body 101, the first reinforcing rib 104 and the second reinforcing rib 105 respectively, or only fixed to the frame body 101 and the first reinforcing rib 104 respectively.

[0044] In this embodiment: At the same time, a sound insulation board 107 is fixed to the outside of the cushioning cotton 108. The sound insulation board 107 is usually made of a material with good sound absorption properties, such as polyester fiber or glass wool, and is fixed to one side of the cushioning cotton 108 to further reduce noise.

[0045] Furthermore;

[0046] In an optional embodiment, a filter 106 is fixed to one side of the frame body 101 to protect the cushioning cotton 108 and the sound insulation board 107.

[0047] In this embodiment, the filter screen 106 is set on one side of the frame body 101 to protect components such as the cushioning cotton 108 and the sound insulation board 107, preventing dust and other particles from entering the interior of the structure. This can improve the effectiveness of the materials in the filling cavity and ensure the cleanliness and functional integrity of the entire system.

[0048] 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.
