Technical Field

[0001] This utility model relates to the field of front bumper technology, specifically to a car front bumper with a protective structure. Background Technology

[0002] With the continuous improvement of people's living standards, the use of cars has become increasingly common. This prevalence of cars has brought significant hidden dangers to current traffic, frequently resulting in traffic accidents. To reduce injuries to drivers in traffic accidents, bumpers have become ubiquitous on existing vehicles. Bumpers serve multiple functions, including safety protection, vehicle decoration, and improving aerodynamic characteristics. From a safety perspective, they act as a buffer in low-speed collisions, protecting the vehicle body; they also provide some protection for pedestrians in accidents. From an aesthetic perspective, they are decorative, becoming an important component in enhancing the appearance of cars; simultaneously, car bumpers also have a certain aerodynamic function. However, current bumper installation methods are simple in structure, and although they are securely fixed, they are inconvenient for installation and removal, causing inconvenience for maintenance personnel.

[0003] To address the aforementioned technical issues, Chinese Patent No. CN221562994U discloses a car front bumper with a protective structure, comprising a front baffle and a front end of the car.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0026] A car front bumper with a protective structure includes a fixed base 1, a connecting cover 2 attached to one side of the fixed base 1, a front baffle 3 mounted on one side of the connecting cover 2, and a buffer assembly installed between the front baffle 3 and the connecting cover 2. One side of the connecting cover 2 is engaged with the fixed base 1 via a docking mechanism. The docking mechanism includes a linkage positioning component and an operating component. The linkage positioning component is used to lock the positions of the connecting cover 2 and the front baffle 3, and the operating component is used to control the linkage positioning component to lock and unlock. In use, the device can lock the positions of the connecting cover 2 and the front baffle 3 through the linkage positioning component, and the operating component controls the linkage positioning component to lock and unlock. The structure is simple and easy to operate. The disassembly and assembly process only requires one worker, saving time and effort, reducing the workload of workers, and further increasing work efficiency.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the linkage positioning assembly includes a docking groove on one side of the outer wall of the fixed base 1. Extension rods are installed at both ends of the connecting cover 2 on the side away from the front baffle 3. A docking block 4 is installed at the other end of the extension rod. The docking block 4 has a U-shaped cross-section. A connecting seat 5 is installed on one side of the inner wall of the docking groove. A movable rod is rotatably connected to the center of one side of the outer wall of the connecting seat 5. A lever 6 is fixedly sleeved on one end of the outer wall of the movable rod. Linkage plates 7 are rotatably connected to both ends of the lever 6. A torsion spring 8 is installed between the outer wall of the movable rod and the outer wall of the connecting seat 5. Limiting grooves are provided at both ends on one side of the outer wall. A limiting block 9 is slidably connected to the inner side of the limiting groove. A limiting spring 10 is installed between one side of the limiting block 9 and the inner wall of the limiting groove. The other end of the linkage plate 7 is rotatably connected to one side of the limiting block 9. The cross-sections of the limiting groove and the limiting block 9 are both T-shaped. First, the connecting cover 2 is overlapped with the outer wall of the fixing seat 1, so that the docking block 4 is inserted into the inner side of the docking groove, and the docking block 4 and the limiting block 9 are in contact. The compression between the inclined surfaces forces the limiting block 9 to retract inside the limiting groove and compress the limiting spring 10.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the opposite ends of the two sets of limiting blocks 9 and docking blocks 4 are provided with corresponding inclined surfaces. A rubber pad 11 is installed on one end of the outer wall of the connecting seat 5. Then, the linkage plate 7 can drive the lever 6 and the movable rod to rotate, so that the torsion spring 8 also retracts. When the docking block 4 is pushed, it will also squeeze the rubber pad 11 to retract. Until the docking block 4 is completely pushed into the docking groove, the reset of the limiting spring 10 and the torsion spring 8 can drive the limiting block 9 to pop out to the protruding end of the docking block 4 to achieve abutment and fixation.

[0029] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the operating assembly includes an operating groove at one end of the top of the fixed base 1. An operating rod 12 is slidably connected to one end inside the fixed base 1. One end of the operating rod 12 extends into the inner side of the docking groove and is fixedly connected to one end of the movable rod. A pull ring is rotatably connected to the end of the operating rod 12 extending into the operating groove. Furthermore, when it is necessary to separate the front baffle 3 and the connecting cover 2, the pull ring inside the operating groove can be fastened to drive the operating rod 12 to rotate. While the operating rod 12 is rotating, it can drive the movable rod to rotate, so that the movable rod actively drives the torsion spring 8 to retract and allows the lever 6 to pull the two sets of linkage plates 7 to deflect. When deflected, it can drive the two sets of limit blocks 9 to actively retract into the limit groove. At this time, the rubber pad 11 is reset and lifts the docking block 4. At this time, releasing the pull ring and the operating rod 12 will not jam the docking block 4 again. Then the connecting cover 2 and the front baffle 3 can be removed.

[0030] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the buffer assembly includes multiple support rods 13 mounted on one side of the front baffle 3. Both ends of the other side of the support rods 13 are rotatably connected to movable plates 14. A push cover 15 is mounted on the bottom end of the support rods 13. A first spring damping shock absorber 19 is installed between the bottom end of the push cover 15 and the inner wall of the connecting cover 2. Synchronization grooves are formed on both sides of the inner wall of the connecting cover 2, located near the push cover 15. A synchronization block 16 is slidably connected inside the synchronization groove. One end of the synchronization block 16 extending outside the synchronization groove is fixedly connected to one side of the push cover 15. A reset groove is formed on the inner wall of the connecting cover 2 near the movable plate 14. A reset plate 17 is slidably connected inside the reset groove. Both ends of one side of the reset plate 17 are fixedly connected to the reset plate 14. Second spring damping shock absorbers 18 are installed between the inner walls of the groove. One end of the movable plate 14 is rotatably connected to the outer wall of the reset plate 17. Furthermore, when the front baffle 3 is deformed by pressure, the support rod 13 can support the inner wall of the front baffle 3, and in conjunction with the synchronizing block 16 and the synchronizing groove, smoothly drive the push cover 15 to move down and squeeze the first spring damping shock absorber 19 to retract, thus achieving initial buffering and force relief. During the downward movement of the support rod 13, it can drive the two sets of movable plates 14 to deflect, so that the reset plate 17 slides inside the reset groove, squeezing each set of second spring damping shock absorbers 18 to retract, further buffering the impact force, and achieving the effect of buffering protection when impacted.

[0031] The implementation principle of a car front bumper with a protective structure in this application embodiment is as follows: The connecting cover 2 overlaps with the outer wall of the fixed seat 1, so that the docking block 4 extends into the inner side of the docking groove, allowing the docking block 4 and the limiting block 9 to contact each other. The compression between the inclined surfaces forces the limiting block 9 to retract inside the limiting groove and compress the limiting spring 10. At the same time, the linkage plate 7 can drive the lever 6 and the movable rod to rotate, causing the torsion spring 8 to also retract. When the docking block 4 is pushed, it will also compress the rubber pad 11 to retract. Until the docking block 4 is completely pushed into the inner side of the docking groove, the reset of the limiting spring 10 and the torsion spring 8 can drive the limiting block 9 to pop out to the protruding end of the docking block 4 to achieve abutment and fixation. When it is necessary to separate the front baffle 3 and the connecting cover 2, the pull ring inside the operating groove can be fastened to drive the operating rod 12 to rotate. When the operating rod 12 rotates, it can drive the movable rod to rotate, so that the movable rod actively drives The torsion spring 8 retracts, causing the lever 6 to pull the two sets of linkage plates 7 to deflect. During the deflection, the two sets of limit blocks 9 can actively retract into the limit groove. At this time, the rubber pad 11 resets and lifts the docking block 4. Releasing the pull ring and operating rod 12 will not cause the docking block 4 to jam again. Then the connecting cover 2 and the front baffle 3 can be removed. When the front baffle 3 is deformed by pressure, the support rod 13 can support the inner wall of the front baffle 3 and, together with the synchronizing block 16 and the synchronizing groove, smoothly drive the push cover 15 to move down and squeeze the first spring damping shock absorber 19 to retract, achieving initial buffering and force relief. During the downward movement of the support rod 13, the two sets of movable plates 14 can be deflected, causing the reset plate 17 to slide inside the reset groove and squeeze each set of second spring damping shock absorbers 18 to retract, further buffering the impact force and achieving the effect of buffering protection when impacted.

[0032] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
