[0002] The connection of various components on existing car seats is usually achieved by clip connection. However, the base structure of the existing clip assembly (such as Figure 1 (As shown in the figure) Due to unreasonable structural design, when assembled in the Y direction and subjected to abuse force testing in the X direction, the samples taken at key points can only withstand a tensile force of about 90N. This structure causes the abuse force test during the development of the side wing components to fail to meet the standards and does not meet the design requirements. Summary of the Invention

[0003] In view of the above-mentioned technical problems and shortcomings, the purpose of the present utility model is to provide a base structure that can withstand an abuse force within 200N in the non-assembly direction. The structure changes the rib distribution of the metal clip base so that the base can withstand greater abuse force on the original basis without damage or deformation, thereby improving the limit of the part's pull-out force in the non-assembly direction. When it maintains the same Y-direction assembly as the original structure and performs an abuse force test in the X-direction, the bearing limit is increased by 110N compared to the original structure, reaching an abuse force of 210N without separation.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] As a preferred embodiment of the present invention, the support ribs of the support seat are arranged below the clip assembly area and close to the non-assembly area.

[0007] Advantages and beneficial effects of the utility model:

[0008] (1) The base structure provided by the present invention changes the rib distribution of the metal clip base, so that the base can withstand greater abuse force on the original basis without damage or deformation, thereby improving the limit of the pull-out force of the parts in the non-assembly direction. When the base structure maintains the same Y-direction assembly as the original structure and is subjected to an abuse force test in the X direction, the bearing limit is increased by 110N compared with the original structure, reaching an abuse force of 210N without separation.

[0009] (2) The base structure provided by the present invention optimizes the rib arrangement of the base on the basis of the original structure, and adds tensioning ribs on the contact surface of the clip to reduce the deformation of the base under stress and reduce the risk of the clip falling out; the outer reinforcement of the base limits the Y-direction deformation of the overall structure and increases the downward pressure bearing strength; the clip support base is supported by the support ribs and the tensioning ribs of the support base to share the X-direction and Y-direction forces, which greatly improves the base's pulling and extrusion bearing capacity and prevents the metal clip from falling out of the base; after the clip is installed through the clip installation port, the clip support ribs protruding from the assembly surface can better limit the up and down movement of the clip and ensure the stability of the assembly.

[0010] (3) The base structure provided by the present invention can be integrally formed with existing plastic parts. This structure can enhance the local strength of the plastic parts and improve the appearance problems of the plastic parts such as deformation due to stress.

[0011] (4) The base structure provided by the present invention has been applied to product development and has been verified by experiments to meet the design requirements, thus solving the problem of abuse of force that does not meet the design requirements during the development of wing-type components.
