Description

Technical Field

[0001] This utility model relates to the field of automotive anti-collision beam technology, specifically a high-strength lightweight front anti-collision beam. Background Technology

[0002] A crash beam is a device used to absorb collision energy when a vehicle is involved in a collision. It consists of a main beam, an energy-absorbing box, and a mounting plate that connects to the car. Both the main beam and the energy-absorbing box can effectively absorb collision energy when a vehicle is involved in a low-speed collision, minimizing the damage to the longitudinal beams of the vehicle body from the impact force. This is how it plays its role in protecting the vehicle.

[0003] A high-strength front bumper beam, with the existing patent publication number "CN212353895U", includes a U-shaped cold-rolled channel steel plate. A reinforcing steel plate is embedded inside the U-shaped cold-rolled channel steel plate, and the reinforcing steel plate has an "S"-shaped structure. The U-shaped cold-rolled channel steel plate is welded and fixed to the reinforcing steel plate. A cold-rolled steel cover plate is bolted to the open end of the U-shaped cold-rolled channel steel plate, and the cold-rolled steel cover plate is pressed tightly against the reinforcing steel plate. Mounting components are welded and fixed to both ends of the U-shaped cold-rolled channel steel plate, and a connecting rod is bolted between the two mounting components. By designing the U-shaped cold-rolled channel steel plate, the cold-rolled steel cover plate, and the reinforcing steel plate, the reinforcing steel plate can expand the stress-bearing surface and buffer energy absorption, reducing the impact force per unit area of ​​the U-shaped cold-rolled channel steel plate. Compared to traditional bumper beams, this bumper beam can withstand higher collision strength, has a lower probability of breakage, and the connecting rod reduces the bending deformation of the mounting components.

[0004] After a car is hit by a minor impact, the front bumper beam will usually show some dents or damage. After damage occurs, in order to ensure the installation during subsequent vehicle operation, these bumper beams need to be replaced as a whole, which increases maintenance costs and makes the replacement process more complicated. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength, lightweight front bumper beam to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength, lightweight front bumper beam, comprising a front bumper beam body, with connecting members symmetrically arranged on both sides of the bottom of the front bumper beam body, a supporting member inside the front bumper beam body, a buffer beam at the top of the front bumper beam body, mounting grooves symmetrically arranged on both sides of the buffer beam, a first clamping plate inside the mounting groove, an mounting rod on one side of the bottom of the first clamping plate, an insertion rod at the bottom of the mounting rod, an insertion tube on the outside of the insertion rod, a second clamping plate at the bottom of the insertion tube, a sliding rod on one side of the top of the second clamping plate, and a locking bolt on one side of the first clamping plate.

[0007] Preferably, a connecting groove is provided on one side of the bottom of the first clamping plate, and the slide rod is located inside the connecting groove. Both the first clamping plate and the slide rod are provided with threaded holes on one side. The locking bolt is adapted to the threaded holes so that the locking bolt can be screwed into the slide rod, thereby connecting the first clamping plate and the second clamping plate and preventing the first clamping plate and the second clamping plate from coming off and causing the connection to loosen.

[0008] Preferably, the top of the connector is provided with a slot, the front bumper beam body is located inside the slot, and the connector is fixed to the front bumper beam body with fixing bolts, so that the front bumper beam body can be inserted into the connector for connection, thereby improving the convenience of connection.

[0009] Preferably, a through hole is provided between the mounting groove and the front anti-collision beam body, and the mounting rod and the insertion tube are both located inside the through hole, which facilitates the docking of the second clamping plate and the first clamping plate.

[0010] Preferably, the support member is composed of multiple sets of reinforcing plates, and the reinforcing plates are arranged in a triangular structure to ensure the overall strength of the front bumper beam body while reducing the weight of the front bumper beam body.

[0011] Preferably, both the first and second clamps are made of an L-shaped structure, with the second clamp located inside the front bumper beam body and the first clamp located inside the mounting groove for easy installation.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the high-strength lightweight front anti-collision beam;

[0013] With the cooperation of the front bumper beam body, buffer beam, and support components, when the front bumper beam is subjected to a small impact force, the front bumper beam body will not be damaged. Instead, the buffer beam will absorb the impact in place of the front bumper beam body, causing damage to the buffer beam. When replacing it, only the buffer beam needs to be replaced, thereby reducing maintenance costs. Furthermore, the internal mounting support components of the front bumper beam body ensure the strength of the front bumper beam as well as the overall strength of the front bumper beam. Then, with the cooperation of the mounting rod, first clamp plate, second clamp plate, locking bolt, sliding rod, and connecting groove, the installation difficulty of the buffer beam is reduced, making it easier to replace.
