[0050] Of course, in other embodiments, multiple locking components 20 may be provided, wherein one or more locking components 20 cooperate with the protection component 30 to achieve dual locking.

[0051] Figure 4 A schematic diagram of the locking assembly 20 of the protective grille device 100 according to an embodiment of the present invention is shown, wherein the locking assembly 20 is in a locked state; Figure 5 A schematic diagram of the locking assembly 20 of the protective grille device 100 according to an embodiment of the present invention is shown, wherein the locking assembly 20 is in the open state; Figure 6 A cross-sectional view of the locking assembly 20 of the protective grille device 100 according to an embodiment of the present invention is shown.

[0052] like Figures 4 to 6 As shown, the locking assembly 20 includes a latch 21 and a lock seat 22, the latch 21 being rotatable to lock or release the lock seat 22.

[0053] In the illustrated embodiment, the latch 21 is mounted on the vehicle body bracket 50, and the lock seat 22 is mounted on the grille bracket 11 of the protective grille 10. In other embodiments, the latch 21 may be mounted on the grille bracket 11 of the protective grille 10, and the lock seat 22 may be mounted on the vehicle body bracket 50. The grille bracket 11 may be mounted on the protective grille 10 or may be integrally formed with the protective grille 10.

[0054] In some embodiments, the lock seat 22 is provided with a lock groove 221 that cooperates with the latch 21. The latch 21 is a U-shaped latch, and the lock seat 22 is provided with two lock grooves 221. The latch 21 can be snapped into the two lock grooves 221 on the lock seat 22, thereby locking the protective grille 10 to the vehicle body bracket 50.

[0055] In some embodiments, the locking assembly 20 further includes a handle 23, which is rotatable to rotate the latch 21, causing the latch 21 to approach or move away from the lock seat 22. When the latch 21 approaches the lock seat 22, the rotating latch 21 engages with the lock groove 221 of the lock seat 22, thereby locking the protective grille 10 to the vehicle body bracket 50.

[0056] In some embodiments, the handle 23 is provided with a locking rotating shaft 24, which is rotatably mounted on the handle 23. The lock 21 is mounted on the locking rotating shaft 24, allowing the lock 21 to rotate around the locking rotating shaft 24. For example, the two ends of the U-shaped lock are respectively mounted on the upper and lower ends of the locking rotating shaft 24.

[0057] In some embodiments, the locking assembly 20 further includes a locking bracket 25, which is mounted on the vehicle body bracket 50, and the handle 23 is rotatably mounted on the locking bracket 25.

[0058] In some embodiments, the locking bracket 25 is provided with a handle rotation shaft 26, and the handle 23 is rotatably mounted on the locking bracket 25 via the handle rotation shaft 26.

[0059] In some embodiments, the locking assembly 20 further includes a trigger 27 for locking or releasing the handle 23. The handle 23 has a retaining hole 231 into which the trigger 27 can engage. For example, as... Figure 6 As shown, the trigger 27 is provided with a slot 271, and the handle 23 is provided with a hook 232 located in the fixing hole 231. The slot 271 of the trigger 27 can be engaged with the hook 232.

[0060] In some embodiments, the locking bracket 20 is further provided with a trigger rotation shaft 28, and the trigger 27 is rotatably mounted on the locking bracket 25 via the trigger rotation shaft 28.

[0061] In some embodiments, a trigger return spring 29 for resetting the trigger 27 is provided between the trigger 27 and the trigger rotation shaft 28.

[0062] In use, pressing or rotating the trigger 27 causes the trigger 27's slot 271 to disengage from the hook 232 in the fixing hole 231, thereby releasing the handle 23. At this time, the handle 23 can rotate, and the trigger 27 returns to its initial position under the action of the trigger return spring 29. Pressing or rotating the trigger 27 inserts the trigger 27 into the fixing hole 231, and the trigger 27 latches onto the hook 232 under the action of the trigger return spring 29, thereby locking the handle 23. At this time, the handle 23 cannot rotate.

[0063] In some embodiments, the locking bracket 20 is further provided with a protective pin (not shown) for securing the handle 23. The protective pin prevents the trigger 27 from releasing the handle 23 due to vibration during vehicle operation, which could potentially cause the protective grille 10 to separate from the vehicle components, ensuring that the handle 23 can only be released by pulling out the protective pin.

[0064] When it is necessary to fix the protective grille 10, first press the trigger 27 to separate the trigger 27 from the fixing hole 231 of the handle 23, thereby releasing the handle 23 so that the handle 23 can rotate around the handle rotation axis 26, driving the latch 21 to approach the lock seat 22. Then rotate the latch 21 around the latch rotation axis 24 to rotate the latch 21 into the lock groove 221 of the lock seat 22. Then rotate the handle 23 back so that the latch 21 locks into the lock groove 221 of the lock seat 22, and the trigger 27 locks the fixing hole 231 of the handle 23, thereby locking the protective grille 10 onto the vehicle body bracket 50.

[0065] When it is necessary to open the protective grille 10, press the trigger 27 again to separate the trigger 27 from the fixing hole 231 of the handle 23, thereby releasing the handle 23 so that the handle 23 can rotate around the handle rotation axis 26, moving the latch 21 away from the locking groove 221 of the lock seat 22, and then moving away from the lock seat 22 as the handle 23 rotates, thereby separating the protective grille 10 from the vehicle body bracket 50.

[0066] Figure 7 A schematic diagram of the protective grille 10 of the protective grille device 100 according to an embodiment of the present invention is shown, wherein the locking component 20 is in a locked state; Figure 8 A schematic diagram of the protective grille 10 of the protective grille device 100 according to an embodiment of the present invention is shown, wherein the locking component 20 is in the open state.

[0067] The locking assembly 20 allows for easy and quick locking of the protective grille 10 to the vehicle component 50, and also allows for easy and quick separation of the protective grille 10 from the vehicle component 50.

[0070] As shown in the figure, in some embodiments, the protective grille device 100 further includes a protective component 30 for locking or releasing the protective grille 10.

[0071] In some embodiments, the protective grille 10 is provided with a grille bracket 11, and the protective component 30 includes a locking pin 31, which is installed on the grille bracket 11. The vehicle body bracket 50 is provided with a locking hole 51, and the locking pin 31 can be inserted into the locking hole 51, thereby further protecting the protective grille 10 from falling off the vehicle body bracket 50.

[0072] In some embodiments, the protection component 30 further includes a locking pin return spring 32 for resetting the locking pin 31.

[0073] In some embodiments, the protective component 30 includes a locking pin cylinder 33, with a locking pin 31 located inside the locking pin cylinder 33 and capable of moving up and down along the locking pin cylinder 33.

[0074] In some embodiments, the locking pin 31 is provided with a handle 311 for rotating the locking pin 31. The locking pin 31 is also provided with a limiting rod 312, and the outer wall of the locking pin cylinder 33 is provided with a limiting groove 34 that cooperates with the limiting rod 312. The limiting rod 312 can move in the limiting groove 34 to realize the switching between the protection state and the release device.

[0075] In some embodiments, the limiting groove 34 is L-shaped and includes a horizontal limiting groove 341 and a vertical limiting groove 342 connected to the horizontal limiting groove 341. The horizontal limiting groove 341 is provided with a slot 343 for locking the limiting rod 312.

[0076] When it is necessary to fix the protective grille 10, the operating handle 311 lifts the locking pin 31 upwards, causing the limiting rod 312 of the locking pin 31 to move away from the slot 343. Then, the locking pin 31 is rotated, and the limiting rod 312 of the locking pin 31 moves along the horizontal limiting groove 341 to the vertical limiting groove 342. Under the action of the spring force of the locking pin return spring 32, the limiting rod 312 of the locking pin 31 moves downwards along the vertical limiting groove 342 to the bottom of the vertical limiting groove 342. At this time, the locking pin 31 is inserted into the locking hole 51 on the body bracket 50, thereby fixing the protective grille 10 to the body bracket 50.

[0077] When the protective grille 10 needs to be opened, the operating handle 311 lifts the locking pin 31 upward, so that the locking pin 31 leaves the locking hole 51 on the body bracket 50. The limiting rod 312 of the locking pin 31 moves upward along the vertical limiting groove 342 to the horizontal limiting groove 341, and then moves along the horizontal limiting groove 341 to the slot 343. At this time, the locking pin return spring 32 is in a compressed state.

[0078] According to the embodiments of this utility model, one or more locking components 20 and one or more protective components 30 can be provided. Both locking components 20 and protective components 30 can fix the protective grille 10 and the vehicle parts. Locking components 20 and protective components 30 can be used alone or in combination. The locking components 20 and protective components 30 cooperate to achieve double locking of the protective grille 10 and the vehicle parts.

[0079] When it is necessary to secure the protective grille 10, rotate the protective grille 10 toward the vehicle component. Considering the large weight of the protective grille 10, first use the protective assembly 30 to secure the protective grille 10, and then use the locking assembly 20 to lock the protective grille 10 to the vehicle component, thereby firmly securing the protective grille 10 to the vehicle component.

[0080] When it is necessary to open the protective grille 10, before opening the locking assembly 20, it is also necessary to release the protection state of the protection system 30. By pulling the locking pin 31, the locking pin return spring 32 is driven to retract, and the locking pin 31 is disengaged from the locking hole 51 on the body bracket 50, thereby releasing the protection state.
