[0002] To enhance the design and three-dimensionality of a car's exterior, some models feature a convex structure in the central area of ​​the front grille assembly. This convex grille assembly typically includes a central grille panel, the main grille body, a left grille body, and a right grille body. The central grille panel is mounted on these three bodies. Currently, central grille panels are often installed using welding or numerous screws. While welding provides a strong connection, it is an irreversible and permanent connection. If the central grille panel or related components are damaged and require repair or replacement, disassembly is extremely inconvenient and may even require destructive removal, increasing repair costs and time. Screw fastening, on the other hand, involves cumbersome assembly procedures, low efficiency, and the excessive number of mounting points can affect the overall aesthetic appearance. Therefore, there is an urgent need for a convenient, easy-to-install, and reliable installation structure for automotive front grille panels. Summary of the Invention

[0003] The purpose of this utility model is to provide a mounting structure for the trim panel in the front grille of an automobile, so as to overcome the problem that the current mounting structure for the trim panel in the front grille of an automobile is inconvenient to disassemble and assemble.

[0004] This utility model is achieved using the following technical solution: a front grille trim panel mounting structure for automobiles, comprising a front grille trim panel, a left grille body, a front grille body, and a right grille body. The back of the front grille trim panel is provided with multiple snap-fit ​​units and multiple guide plates. Each snap-fit ​​unit includes a mounting plate fixedly connected to the back of the front grille trim panel, and an elastic snap head detachably mounted on the mounting plate. The elastic snap head includes two side plates, forming a space between the side plates to accommodate the mounting plate. Each side plate is provided with an outwardly protruding elastic snap piece, both of which are V-shaped and arranged opposite to each other.

[0016] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0017] This utility model provides a mounting structure for a trim panel in a car's front grille. This structure is mainly applied to front grille assemblies with a convex design. The front grille assembly mainly consists of a front grille trim panel 1, a front grille body 3, a left grille body 2, and a right grille body 4.

[0018] The back of the trim panel 1 in the front grille is designed with multiple mounting points based on its contact area with the left grille body 2, the front grille body 3, and the right grille body 4. These mounting points include two types: one is a snap-fit ​​unit, which provides the main locking force; the other is a guide plate 5, which is used for initial guidance. Correspondingly, the front grille body 3, the left grille body 2, and the right grille body 4 are precisely provided with snap holes 10 corresponding to the positions of the elastic snap heads 7 on the snap-fit ​​units, and guide holes 11 corresponding to the positions of the guide plates 5.

[0019] The snap-fit ​​unit adopts a split design, comprising a mounting plate 6 and a flexible snap-fit ​​head 7. The mounting plate 6 is preferably integrally formed with the back of the trim panel 1 in the front grille, and has limiting flanges 16 on its left and right sides. The flexible snap-fit ​​head 7 is typically made of spring steel with good elasticity, and is roughly U-shaped, including two side plates 8 and a connecting portion 12 connecting the top of the two side plates 8. A space is formed between the two side plates 8 to accommodate the mounting plate 6, i.e., the mounting plate 6 is inserted between the two side plates 8. A groove 13 is respectively provided in the middle of the two side plates 8, and the upper part of each side groove 13 is connected to an outwardly protruding flexible snap-fit ​​piece 9. The flexible snap-fit ​​piece 9 itself is V-shaped, and the two flexible snap-fit ​​pieces 9 are arranged opposite each other. The lower part of the two side grooves 13 is connected to inwardly inclined claws 14. Each side groove 13 can connect two claws 14. The claws 14 on both sides of the side grooves 13 extend towards the mounting plate 6. The heads of the claws 14 on both sides of the side grooves 13 abut against the plate surface of the mounting plate 6 and engage with the plate body of the mounting plate 6. The heads of the claws 14 are pointed, which facilitates better gripping of the plate body of the mounting plate 6. The elastic clamp 7 is fitted onto the mounting plate 6 from top to bottom through its U-shaped opening. The claws 14 on both sides of the side grooves 13 grip the plate body of the mounting plate 6 under the action of elasticity. At the same time, the limiting stops 16 on both sides of the mounting plate 6 restrict the lateral movement of the elastic clamp 7, thereby achieving a stable and detachable connection between the two. The two supporting base plates 15 at the bottom of the elastic clamp 7 contact the bottom surface of the clamping hole 10 during installation, playing a supporting and limiting role. The lower end of the elastic snap-fit ​​piece 9 is connected to a downwardly extending extension section 24, which is generally vertical.

[0020] The process of removing and installing the trim panel 1 in the front grille: During installation, first insert the guide plate 5 on the back of the trim panel 1 in the corresponding guide hole 11 on the grille body to achieve positioning and guidance. The V-shaped elastic snap piece 9 includes a front slope and a rear slope, and the front slope and the rear slope are connected to form a V-shaped structure. Then, press the front grille trim panel 1 towards the vehicle body. Multiple elastic clips 7 are simultaneously inserted into the corresponding clip holes 10. When the elastic clips 7 are inserted, the front slope of the elastic clip 9 first contacts the edge of the clip hole 10. As the pressing continues, the inner wall of the clip hole 10 forces the two elastic clips 9 to bend inward elastically by squeezing the front slope of the elastic clips 9 on both sides until the front slope of the elastic clips 9 on both sides passes through the clip hole 10. At this time, the rear slope of the elastic clip 9 contacts the clip hole 10. During the process of the rear slope contacting the clip hole 10 and sliding with each other, the elastic clip 9 gradually recovers its deformation outward under the action of elasticity. After the rear slope of the elastic clip 9 passes through the clip hole 10, the extension section 24 will contact the clip hole 10. Finally, the two side support base plates 15 contact the bottom of the clip hole 10. At this time, the elastic clips 7 are inserted in place, and the end of the extension section 24 is also inserted into the clip hole 10. The two side elastic clips 9 are still in a state of inward elastic bending deformation. During disassembly, simply pull the front grille trim panel 1 outwards. The extension 24 on the elastic clip 9 first passes outwards through the clip hole 10, and then the rear and front slopes of the elastic clip 9 successively contact the clip hole 10, causing the elastic clip 9 to elastically deform inwards until the elastic clip head 7 exits the clip hole 10. If any elastic clip head 7 is damaged during the disassembly and assembly of the front grille trim panel 1, it can be pried off the mounting plate 6 and replaced with a new elastic clip head 7, which is economical and convenient.

[0021] To further optimize the structure and appearance, a left lug 17 and a right lug 18 can be integrally formed on both sides of the front grille trim panel 1. The left lug 17 extends to the left of the front grille trim panel 1 body, and the right lug 18 extends to the right of the front grille trim panel 1 body. Small light mounting holes are provided on the left lug 17 and right lug 18 respectively. A left mounting hole corresponding to the small light hole 25 on the left lug 17 is provided on the left grille body 2, and a right mounting hole corresponding to the small light hole 25 on the right lug 18 is provided on the right grille body 4. Multiple snap-fit ​​units are installed on the back of the left lug 17 and the back of the right lug 18 for fixation. More optimally, continuous slots are provided on the outer surfaces of the front grille body 3, the left grille body 2, and the right grille body 4: a left slot 20 is provided on the left grille body 2, a right slot 21 is provided on the right grille body 4, and middle slots 22 are provided on the upper and lower sides of the front grille body 3. These slots are connected end-to-end to form a closed-loop annular slot 19. Simultaneously, a continuous annular limiting protrusion 23 is provided on all outer edges of the front grille trim panel 1 (including the edge of the left lug 17 and the edge of the right lug 18). After the front grille trim panel 1 is installed in place, this limiting protrusion will simultaneously embed into the annular groove 19. This structure not only provides additional restraint to prevent the front grille trim panel 1 from shaking, but also ensures that the assembly gap width between the front grille trim panel 1 and surrounding components is consistent and uniform, improving the overall visual appeal and refinement. The locking hole 10 can be opened at the bottom of the annular groove 19, and the guide plate 5 can be installed on the end face of the annular limiting protrusion 23.
