Description

Technical Field

[0001] The utility model relates to the field of automobile accessories, and more specifically to a rear anti-collision beam mounting plate welding structure which is easy to assemble. Background Art

[0002] The rear anti-collision beam assembly is a device installed at the rear of the car to reduce the impact energy when the vehicle is hit from behind. An important concept in the passive safety of the car body is that if a point is stressed, the whole body will be stressed. If the entire skeleton structure is used to bear the force when a certain point is stressed, the strength of the force on that point can be reduced to the maximum extent. In particular, the rear anti-collision steel beam plays a very obvious role here.

[0003] The Chinese patent authorization announcement number: CN209581396U provides a rear anti-collision beam assembly for an automobile. The rear cross beam of this patent is welded with the left and right energy absorption box assemblies. The energy absorption box can be embedded in the interior of the rear cross beam, which increases the accuracy of positioning and the rationality of the welding area, improves the welding method and welding area, and greatly enhances the welding strength and rigidity; the arched structure of the rear cross beam can effectively enhance its structural strength. When the car collides, the rear anti-collision beam has a certain elasticity and is not easy to deform, which can buffer and absorb the collision energy; in addition, an auxiliary buffer structure is provided to further buffer the impact force of the car; when the collision energy reaches the limit value, the rear cross beam will collapse and absorb energy through the energy absorption box, reducing the spatial deformation of the rear of the car and reducing the damage to the rear passengers.

[0004] The above-mentioned rear cross beam is welded to the left and right energy absorption box assemblies, which results in the need for violent disassembly when the rear anti-collision beam is bumped and needs to be replaced during driving of the vehicle, which may easily cause damage to the energy absorption box or the frame connected to the energy absorption box.
