Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a front grille assembly with multiple fixing structures. Background Technology

[0002] The front grille is a key component of the front of a car, serving multiple functions such as decorating the car's appearance, guiding airflow to cool the engine compartment, and protecting internal components from impacts. Its installation stability and ease of assembly directly affect the car's production efficiency and reliability.

[0003] In Chinese utility model patents, such as CN217969452U, a front grille assembly with multiple fixing structures is disclosed. This assembly uses elastic clips on the grille frame, with clips connected to these clips installed at the front grille mounting position. The grille frame is fixed by inserting the elastic clips into the clips, making fixing convenient and easy to disassemble. Furthermore, two threaded holes are provided on the second upright plate of the grille frame, with fixing bolts threaded into these holes. After the grille frame is fixed, it is further reinforced by these two fixing bolts, improving the fixing effect. The number of fixing bolts is small, and it does not affect the efficiency of grille disassembly.

[0004] However, the above-mentioned technology relies on the single snap-fit ​​of the elastic clip and the buckle to achieve initial fixation. Long-term vibration can easily cause the snap-fit ​​to loosen, resulting in insufficient fixation stability. Furthermore, it requires reinforcement with fixing bolts, which increases the need for tools. In view of this, this application proposes a front grille assembly with multiple fixing structures. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a front grille assembly with multiple fixing structures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A front grille assembly with multiple fixing structures includes a grille frame and multiple mounting plates. Multiple positioning plates are symmetrically mounted on the outer side of the grille frame. Two retaining sleeves are symmetrically mounted on the outer side of each positioning plate. Two insert plates are slidably connected to the outer side of each mounting plate via an unfolding mechanism, and each insert plate is locked within a corresponding retaining sleeve. An insert block is fixedly mounted on the outer side of each positioning plate. A second spring telescopic rod is fixedly mounted on the top surface of each mounting plate. A first wedge block is mounted at the bottom end of each second spring telescopic rod, and each first wedge block is locked within a corresponding insert block. A T-shaped plate is slidably connected within each insert block. A second wedge block is mounted at one end of each T-shaped plate, and the wedge-shaped surface of each second wedge block is in contact with the wedge-shaped surface of the first wedge block.

[0008] Preferably, each of the unfolding mechanisms includes an assembly plate, and each assembly plate is fixedly installed on one side of the mounting plate. A fixed frame is elastically slidably connected to the outer side of each assembly plate. Two moving blocks are symmetrically slidably connected within each fixed frame. Each insert plate is fixedly installed on the outer side of the corresponding moving block. Multiple connecting rods are symmetrically rotatably connected to the outer side of each mounting plate, and the other end of each connecting rod is rotatably connected to the outer side of the corresponding moving block.

[0009] Preferably, each of the inserts has a groove on its top surface, and each first wedge is engaged in the corresponding groove.

[0010] Preferably, the side of each insert block away from the positioning plate is inclined, and the inclination angle of the inclined surface is consistent with the inclination angle of the wedge surface of the first wedge block.

[0011] Preferably, one end of each T-shaped plate passes through the positioning plate and the grid frame, and multiple covers are symmetrically attached to the outer side of the grid frame, with each cover used to hide the T-shaped plate.

[0012] Preferably, a plurality of first spring telescopic rods are symmetrically installed on the outer side of each assembly plate, and the other end of each first spring telescopic rod is fixedly connected to the outer side of the corresponding fixed frame.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model achieves boltless double fixing of the grid frame and the mounting plate through devices such as the unfolding mechanism, insert plate, sleeve, second spring telescopic rod, and first wedge block. The unfolding mechanism drives the insert plate to automatically snap into the sleeve to complete the initial fixing, and the second spring telescopic rod pushes the first wedge block to embed into the insert block to achieve secondary fixing. This not only reduces the problem of bolt use, but also improves the structural stability through double snap-fit, while simplifying the installation steps and improving assembly efficiency.

[0015] 2. This utility model achieves a balance between convenient disassembly and aesthetic optimization through devices such as a T-shaped plate, a second wedge block, and a cover. Pushing the T-shaped plate through the positioning plate and the grid frame can cause the second wedge block to push the first wedge block away from the insert block, thus quickly completing the disassembly. The cover, which is fixed on the outside of the grid frame, can hide the T-shaped plate and prevent it from being exposed and affecting the appearance. Attached Figure Description

[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] This utility model provides a technical solution: such as Figure 1-5 As shown, a front grille assembly with multiple fixing structures includes a grille frame 1 and multiple mounting plates 4. Multiple positioning plates 3 are symmetrically installed on the outer side of the grille frame 1. Two sleeves 5 are symmetrically installed on the outer side of each positioning plate 3. Two insert plates 13 are slidably connected to the outer side of each mounting plate 4 through an unfolding mechanism, and each insert plate 13 is locked in the corresponding sleeve 5. An insert block 7 is fixedly installed on the outer side of each positioning plate 3. A second spring telescopic rod 14 is fixedly installed on the top surface of each mounting plate 4. A first wedge block 15 is installed at the bottom end of each second spring telescopic rod 14, and each first wedge block 15 is locked in the corresponding insert block 7. A T-shaped plate 6 is slidably connected in each insert block 7. A second wedge block 17 is installed at one end of each T-shaped plate 6, and the wedge surface of each second wedge block 17 is in contact with the wedge surface of the first wedge block 15.

[0024] The double engagement of the insert plate 13 and the sleeve 5, and the first wedge block 15 and the insert block 7, greatly improves the fixing stability. The T-shaped plate 6 and the second wedge block 17 work together to provide a convenient operation point for subsequent disassembly, taking into account both stability and maintenance convenience, and no additional bolts are required for fixing.

[0025] Furthermore, each deployment mechanism includes an assembly plate 8, and each assembly plate 8 is fixedly installed on one side of the mounting plate 4. A fixed frame 11 is elastically slidably connected to the outer side of each assembly plate 8. Two moving blocks 10 are symmetrically slidably connected inside each fixed frame 11. Each insert plate 13 is fixedly installed on the outer side of the corresponding moving block 10. Multiple connecting rods 12 are symmetrically rotatably connected to the outer side of each mounting plate 4, and the other end of each connecting rod 12 is rotatably connected to the outer side of the corresponding moving block 10.

[0026] With the help of the rotation transmission of the connecting rod 12, the moving block 10 and the insert plate 13 can slide within the fixed frame 11, so that the insert plate 13 can automatically unfold and accurately snap into the sleeve 5. There is no need to manually adjust the position of the insert plate 13, simplifying the installation steps and improving the assembly efficiency.

[0027] Furthermore, each insert 7 has a groove 16 on its top surface, and each first wedge 15 is engaged in the corresponding groove 16.

[0028] The groove 16 provides a precise snap-fit ​​positioning space for the first wedge block 15, enabling the first wedge block 15 to be stably embedded in the insert block 7, preventing the first wedge block 15 from shifting or falling off during use, further enhancing the reliability of secondary fixing, and ensuring the stability of the connection between the grid frame 1 and the mounting plate 4.

[0029] Furthermore, the side of each insert 7 away from the positioning plate 3 is inclined, and the inclination angle of the inclined surface is consistent with the inclination angle of the wedge surface of the first wedge block 15.

[0030] The tilt angle matching allows the first wedge block 15 to slide along the tilt surface of the insert block 7 when it is pushed, and then insert it into the groove 16.

[0031] Furthermore, one end of each T-shaped plate 6 passes through the positioning plate 3 and the grid frame 1, and multiple covers 2 are symmetrically attached to the outer side of the grid frame 1, and each cover 2 is used to hide the T-shaped plate 6.

[0032] The T-shaped plate 6 is designed to allow for easy operation from the outside of the grille frame 1 to control the second wedge block 17. The cover 2 can hide the T-shaped plate 6 to prevent it from being exposed and affecting the aesthetics of the car's appearance.

[0033] Furthermore, multiple first spring telescopic rods 9 are symmetrically installed on the outer side of each assembly plate 8, and the other end of each first spring telescopic rod 9 is fixedly connected to the outer side of the corresponding fixed frame 11.

[0034] This utility model provides a front grille assembly with multiple fixing structures, the specific working principle of which is as follows:

[0035] First, fix the mounting plate 4 to the preset position on the car body, and then move the grille frame 1 toward the mounting plate 4;

[0036] At this time, the positioning plate 13 in the unfolding mechanism is in contact with the side of the positioning plate 3. Then, the first spring telescopic rod 9 is compressed and moves towards the assembly plate 8. During the movement of the fixed frame 11, the connecting rod 12 is driven to rotate, which in turn pushes the moving block 10 to slide symmetrically in the fixed frame 11, so that the insert plate 13 unfolds synchronously and is accurately inserted into the sleeve 5 on the positioning plate 3, thus completing the initial fixation.

[0037] Simultaneously, the insert 7 contacts the first wedge block 15. Utilizing the matching inclined surfaces of the two, the first wedge block 15 is compressed and the second spring telescopic rod 14 moves upward. After the grid frame 1 is in place, the second spring telescopic rod 14 resets, pushing the first wedge block 15 into the groove 16 of the insert 7 to achieve secondary fixation. During disassembly, the cover 2 is removed, the T-shaped plate 6 is pushed to move the second wedge block 17, pushing the first wedge block 15 out of the groove 16, and then the grid frame 1 is pulled. The first spring telescopic rod 14 resets, causing the insert plate 13 to retract, thus completing the disassembly.

[0038] 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.
