Description

Technical Field

[0001] This utility model belongs to the field of automotive parts and devices technology, specifically relating to a trunk panel snap-fit ​​structure. Background Technology

[0002] In the automotive manufacturing industry, the trunk of a car is typically composed of a stamped metal panel and internal plastic structural components. The assembly quality of these two components directly affects the overall performance and appearance of the trunk. Currently, in existing technologies, after assembling the stamped metal panel and internal plastic structural components of the trunk, an additional bending process is often required to achieve specific structural requirements or aesthetic effects. This extra bending process not only increases the complexity of the production process and significantly increases the number of assembly steps, but also leads to reduced production efficiency and increased production costs.

[0003] Furthermore, the existing assembly method results in a tight and difficult-to-separate connection between the metal panel and plastic structural components after installation, making disassembly virtually impossible. When the trunk suffers partial damage requiring repair, or when internal structural components need to be replaced due to other after-sales needs, the inability to disassemble often necessitates replacing the entire component. This not only wastes resources but also significantly increases after-sales repair costs and complexity, reducing user experience and after-sales satisfaction. Therefore, a new technological solution is urgently needed to address the cumbersome assembly process and difficult disassembly for automotive trunks. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a trunk panel snap-fit ​​structure to solve the problems of complex assembly processes and inability to disassemble existing trunk panels. This trunk panel snap-fit ​​structure is simple to assemble and has the feature of being detachable.

[0005] This utility model discloses a trunk panel snap-on structure, including a metal panel and a plastic structural component. The outer edge of the metal panel has an insertion head protruding from it. The insertion head is flat, and the end surface of the insertion head away from the metal panel has a raised structure. The cross-sectional height of the raised structure gradually decreases along the direction away from the metal panel. The plastic structural component has a stepped portion bent at 90°. One side surface of the stepped portion has a U-shaped groove, and an elastic sheet is formed inside the U-shaped groove. The metal panel is located at the inner corner of the stepped portion, and the insertion head is inserted into the U-shaped groove. The end of the elastic sheet abuts against the raised structure.

[0006] Furthermore, the number of the insertion heads is multiple, and correspondingly, the number of the U-shaped grooves is also multiple.

[0007] Furthermore, the plastic structural component is provided with reinforcing ribs on the stepped portion.

[0008] The trunk panel snap-fit ​​structure, by featuring a flat insert with a specific protrusion on the outer edge of the metal panel and a U-shaped groove with an elastic tab on the stepped portion of the plastic structural component, changes the traditional method of requiring additional bending after assembly. During assembly, the insert is inserted into the U-shaped groove, and the elastic tab engages with the protrusion, directly and securely assembling the metal panel and plastic structural component without the need for additional bending. This significantly reduces the number of assembly steps, improves production efficiency, and lowers production costs. Furthermore, during after-sales maintenance, applying force to deform the elastic tab releases the engagement between the protrusion and the elastic tab, allowing for the disassembly of the metal panel and plastic structural component. Compared to existing technologies where disassembly is virtually impossible after installation, this greatly reduces the difficulty and cost of after-sales maintenance, facilitates the repair and replacement of damaged parts, and enhances the user's after-sales experience.

[0012] This utility model discloses a trunk panel buckle structure, which is simple to assemble and has the feature of being detachable.

[0013] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of the embodiments of this utility model, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0014] See Figure 1 and Figure 2As shown, this utility model discloses a trunk panel snap-on structure, including a metal panel 2 and a plastic structural component 1. The outer edge of the metal panel 2 is provided with an insertion head 6 protruding from the metal panel 2. The insertion head 6 is flat, and the end surface of the insertion head 6 away from the metal panel 2 is provided with a protruding structure 7. Along the direction away from the metal panel 2, the cross-sectional height of the protruding structure 7 gradually decreases. The plastic structural component 1 is provided with a step portion 3 bent at 90°. A U-shaped groove 5 is formed on one side surface of the step portion 3. An elastic sheet 4 is formed inside the U-shaped groove 5. The metal panel 2 is located at the inner corner of the step portion 3, and the insertion head 6 is inserted into the U-shaped groove 5. The end of the elastic sheet 4 abuts against the protruding structure 7.

[0015] The trunk panel snap-fit ​​structure, by providing a flat insertion head 6 with a specific protruding structure 7 on the outer edge of the metal panel 2 and a U-shaped groove with an elastic piece 4 on the stepped portion 3 of the plastic structural component 1, changes the traditional mode that requires additional bending after assembly. During assembly, the insertion head 6 is inserted into the U-shaped groove, and the elastic piece 4 engages with the protruding structure 7, directly completing the secure assembly of the metal panel 2 and the plastic structural component 1 without the need for additional bending processes. This significantly reduces the number of assembly steps, improves production efficiency, and lowers production costs. Furthermore, during after-sales maintenance, applying force to the elastic piece 4 to deform it releases the engagement between the protruding structure 7 and the elastic piece 4, allowing for the disassembly of the metal panel 2 and the plastic structural component 1. Compared to existing technologies where disassembly is virtually impossible after installation, this greatly reduces the difficulty and cost of after-sales maintenance, facilitates the repair and replacement of damaged parts, and improves the user's after-sales experience.

[0016] There are multiple insertion heads 6, and correspondingly, there are also multiple U-shaped grooves 5.

[0017] The combination of multiple inserts 6 and U-shaped grooves can form a stable connection at multiple points between the metal panel 2 and the plastic structural component 1. Compared with the assembly method of a single insert 6 and U-shaped groove, it enhances the connection strength and stability of the overall structure, making the trunk panel less prone to loosening or falling off during external force or long-term use, and further ensuring the performance and reliability of the car trunk.

[0018] The plastic structural component 1 is provided with reinforcing ribs 8 on the stepped portion 3.

[0019] During the assembly of the metal panel 2 and the plastic structural component 1, the reinforcing rib 8 can disperse the squeezing force generated when the insert head 6 is inserted, preventing the plastic structural component 1 from deforming or being damaged due to concentrated force. During use, it can also better withstand the weight of items placed in the trunk and external forces such as bumps during driving, improving the stability and reliability of the plastic structural component 1 during assembly and use with the metal panel 2, extending the service life of the trunk panel buckle structure, and reducing the need for maintenance and replacement due to insufficient structural strength.

[0020] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
