Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a high-strength automobile anti-collision beam bracket. Background Art

[0002] The anti-collision beam of an automobile is a device used to absorb the impact force when the automobile collides. The anti-collision beam is usually made of steel to achieve high strength of the anti-collision beam. However, when the car collides with a person, the strength of the anti-collision beam will cause great harm to the human body. Therefore, a thin steel plate thinner than the anti-collision beam will be set in front of the automobile anti-collision beam to form a protective beam, which will replace the anti-collision beam and contact the human body to reduce damage to the human body. A bracket for supporting the protective beam is provided inside the protective beam. The bracket is fixedly connected to the inner wall of the protective beam by welding. Due to its thin thickness, the protective beam is more likely to deform during a collision. Therefore, it needs to be replaced when it is deformed. During replacement, due to the welding of the bracket to the protective beam, it is not convenient to disassemble and it will be discarded together with the protective beam, causing waste.

[0028] The limiting component is used to limit the movement of the bracket component 4, and the limiting component is arranged at the bottom end of the inner wall of the protection beam 3.

[0029] Specifically, the top and bottom ends of the energy absorption box 2 are respectively provided with fixing bolts 5, which are used to connect the anti-collision beam 1, the protection beam 3 and the energy absorption box 2. The top and bottom ends of the anti-collision beam 1 are respectively provided with a first circular hole, the top and bottom ends of the protection beam 3 are respectively provided with a second circular hole, and the top and bottom ends of the energy absorption box 2 are respectively provided with a threaded groove, and the fixing bolts 5 are inserted and connected to the inside of the first circular hole, the second circular hole and the threaded groove.

[0030] Furthermore, the anti-collision beam 1 is an existing automobile anti-collision beam made of steel, and the energy absorption box 2 is an existing corrugated energy absorption box, which is used to be fixedly connected to the vehicle frame. The fixed connection method is a bolt connection, and the inner wall of the threaded groove is provided with a thread, and the thread is engaged with the thread on the outer wall of the fixing bolt 5. The inner walls of the first circular hole and the second circular hole are both smooth inner walls. The diameter of the first circular hole and the second circular hole is 1.01 times the outer diameter of the screw rod of the fixing bolt 5. The fixing bolt 5 is connected with the first circular hole and the second circular hole through insertion and insertion, and is connected with the thread of the threaded groove through insertion and insertion, so that the anti-collision beam 1 and the protection beam 3 are squeezed and fixed to the end of the energy absorption box 2. The material of the protection beam 3 is the same as that of the anti-collision beam 1, but the protection beam 3 is a thin steel plate with a thickness of 1 mm.

[0031] Specifically, the end of the protective beam 3 away from the anti-collision beam 1 is bow-shaped, a third circular hole is opened at the top of the front of the protective beam 3, and a fourth circular hole is opened at the front of the top plate 45.
