[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figures 1 to 4 As shown, the utility model provides an easily disassembled automobile bumper, comprising a bumper shell 1;

[0028] Both sides of the back of the bumper shell 1 are fixedly connected to brackets 2, and a shaft 3 is inserted into the inner side of the bracket 2. The surface of the shaft 3 is fixedly connected to claws 4 located on both sides of the bracket 2. The top of the bracket 2 is fixedly connected to a hook 5 that cooperates with the claw 4. After swinging with the shaft 3, the claw 4 can be inserted into the hook 5 to form a closed loop. The bumper shell 1 is hung on the surface of the front beam of the vehicle through the closed loop formed by the claw 4 and the hook 5.

[0029] refer to Figure 3 A screw 6 is provided inside the bumper shell 1, and a screw sleeve 7 is threadedly connected to the surface of the screw 6. Both sides of the surface of the shaft rod 3 are fixedly connected with a sleeve 8 located on the inner side of the claw 4. The sleeve 8 extends to the outside of the screw sleeve 7 away from the side of the shaft rod 3. A sliding rod 9 is fixedly connected on both sides of the screw sleeve 7. The sliding rod 9 extends to the inside of the sleeve 8 away from the side of the screw sleeve 7. The sleeve 8 and the sliding rod 9 are slidably connected. The screw sleeve 7 can carry the sliding rod 9 down through the thread and pull the sleeve 8 to swing. After swinging, a triangular structure is formed between the sleeve 8, the bumper shell 1 and the bracket 2.

[0030] As a technical optimization solution of the present invention, through the threaded connection between the screw 6 and the sleeve 7, and the mechanism in which the sleeve 7 drives the slide rod 9 to descend and pulls the sleeve 8 to swing, the bumper can form a more stable triangular structure after installation, thereby enhancing the connection strength between the bumper and the front beam of the vehicle and improving the safety of the vehicle in the event of a collision.

[0031] refer to Figure 3 The back of the bumper housing 1 is fixedly connected to a connecting frame 10 , and the screw 6 is movably connected to the inside of the connecting frame 10 through a bearing. The bottom end of the screw 6 passes through the connecting frame 10 and extends to the bottom of the connecting frame 10 .

[0032] As a technical optimization solution of the present invention, the design of the movable connection between the connecting frame 10 and the screw 6 bearing allows the screw 6 to rotate flexibly without affecting the stability of the bumper shell 1. At the same time, the bottom end of the screw 6 passes through the connecting frame 10 and extends to the bottom of the connecting frame 10, providing sufficient space for the movement of the screw sleeve 7, thereby ensuring the firmness and stability of the bumper installation.

[0033] refer to Figure 3 The left and right sides of the connecting frame 10 are fixedly connected with guide rods 11, which are located on both sides of the screw rod 6. The screw sleeve 7 is sleeved on the surface of the guide rod 11, and the guide rod 11 is slidably connected to the screw sleeve 7.

[0034] As a technical optimization solution of the present invention, the setting of the guide rod 11 limits the moving direction of the screw sleeve 7, so that the screw sleeve 7 can only move up and down along the direction of the guide rod 11, which not only improves the stability of the movement of the screw sleeve 7, but also prevents the screw sleeve 7 from deflecting or getting stuck during the movement, thereby ensuring the accuracy and reliability of the bumper installation.

[0035] refer to Figure 3 The front of the sleeve plate 8 is fixedly connected with an elastic plate 12, and the side of the elastic plate 12 away from the sleeve plate 8 contacts the back of the bumper shell 1, and the elastic plate 12 is elastic.

[0036] As a technical optimization solution of the present invention, the setting of the spring plate 12 enables the sleeve 8 to be in close contact with the back of the bumper shell 1 during the swinging process, thereby increasing the stability of the bumper. At the same time, the elastic characteristics of the spring plate 12 can also absorb and disperse the impact force during the collision to a certain extent, thereby improving the buffering performance of the bumper.

[0037] refer to Figure 3 The bottom of the screw sleeve 7 is fixedly connected with a plug-in plate 13, which extends to the back of the connecting frame 10 away from the side of the screw sleeve 7. The bottom of the plug-in plate 13 is set to an arc shape, and the plug-in plate 13 can be plugged into the inside of the front beam at the bottom of the vehicle during the process of the screw sleeve 7 descending.

[0038] As a technical optimization solution of the present invention, the connection strength between the bumper and the front beam of the vehicle is further enhanced by the design that the plug-in plate 13 follows the screw sleeve 7 to descend and is plugged into the interior of the front beam at the bottom of the vehicle.

[0039] The working principle and use process of the present invention are as follows: the bumper shell 1 is connected to the front beam of the vehicle through the brackets 2 fixedly connected on both sides of its back side and the shaft 3 inserted into the inner side of the bracket 2. The claws 4 fixedly connected to the shaft 3 can be separated from the hooks 5 on the top of the bracket 2 in the initial state following the swing of the shaft 3. When the bumper needs to be installed, the operator brings the bumper shell 1 close to the front beam of the vehicle and swings the shaft 3 so that the claws 4 follow the shaft 3 and swing to a position relative to the hook 5. Then, the screw 6 is rotated to move the screw sleeve 7 downward along the thread of the screw sleeve 6. The movement of the screw sleeve 7 will drive the sliding rods 9 fixedly connected on both sides to descend, and the sliding rods 9 extend to the inside of the sleeve plate 8 and are connected to the sleeve plate. The plate 8 is slidably connected, so the descent of the screw sleeve 7 will pull the sleeve plate 8 to swing, so that a triangular structure is formed between the sleeve plate 8, the bumper shell 1 and the bracket 2. This triangular structure increases the connection strength and stability between the bumper and the front beam of the vehicle. At the same time, the claw 4 can be inserted into the hook 5 and plugged into the hook 5 to form a closed loop. This closed loop ensures that the bumper shell 1 can be firmly hung on the surface of the front beam of the vehicle. Finally, the plug-in plate 13 fixedly connected to the bottom of the screw sleeve 7 can be plugged into the inside of the bottom front beam of the vehicle during the descent of the screw sleeve 7. This step further enhances the connection stability between the bumper and the front beam of the vehicle and ensures the safety and reliability of the bumper during vehicle driving.

[0040] In summary, the easily disassembled automobile bumper realizes convenient hanging of the bumper and the front beam of the vehicle through the design of the bracket 2, shaft 3, claw 4 and hook 5 on the back of the bumper shell 1, making the installation and removal process of the bumper simple and quick without the use of complex tools or equipment, thereby improving the efficiency of repairing and replacing the bumper.
