Description

Technical Field

[0001] This utility model relates to the field of vehicle body, specifically to a mounting end plate for mounting a crash beam and a crash beam assembly having the mounting end plate. Background Technology

[0002] Mounting end plates are important connecting structural components at the front of a car body. Their main function is to act as an intermediate carrier to reliably install and connect the front bumper beam assembly to the end of the front longitudinal beam of the vehicle body.

[0003] The front bumper beam is a key component for vehicle passive safety. Its ability to absorb and transfer energy during a collision largely depends on the stiffness and strength of the connection structure between it and the vehicle's longitudinal beams.

[0004] Therefore, the design of the mounting end plate is crucial. It needs to have sufficient structural strength to transfer collision loads and ensure the accuracy and stability of the connection.

[0005] In traditional automotive body structures, the mounting plate of the front bumper beam has a relatively simple function, typically focusing solely on connecting the bumper beam to the longitudinal beams. However, with the development of automotive technology, especially the popularization of new energy vehicles and the strengthening trend of modular and integrated vehicle design, the layout of the front compartment of automobiles is becoming increasingly compact, with more and more integrated components. Plastic front-end frames, as a highly integrated lightweight module, have been widely adopted. This frame integrates multiple components such as radiators, condensers, headlights, and sensors, and it itself needs to be fixed to the vehicle body structure through multiple mounting points.

[0006] The current common arrangement is that the mounting end plate of the front bumper beam and the mounting bracket or mounting point of the front frame are independent of each other, and are designed and connected separately. This separate design has several drawbacks: First, it increases the number of parts and mold costs, leading to more complex material management and assembly processes; second, multiple independent mounting points disperse the structural load path, which may affect the overall stiffness coordination of the front compartment; third, independent brackets occupy more front compartment space, which is not conducive to achieving a compact layout; finally, during assembly, the bumper beam and the front frame need to be positioned and fastened separately, and there is room for improvement in assembly efficiency.

[0007] Existing patent CN 116279253 A discloses a rear bumper beam assembly and a vehicle. The mounting end plate in this patent is only used for the connection between the rear bumper beam and the longitudinal beam.

[0008] Therefore, in order to improve or solve at least one of the above technical problems, it is necessary to redesign the structure of the existing mounting end plate. Utility Model Content

[0011] The lap joint plate includes a first end plate and a second end plate. The second end plate is connected to the base plate through the first end plate. The second end plate and the base plate are staggered and parallel. The first end plate is inclined.

[0012] The lap joint plate is a stepped plate.

[0013] The end plate body has a reinforced flange at its edge.

[0014] The base connecting plate is a flat plate structure.

[0017] The base connecting plate in the mounting end plate of the anti-collision beam is welded to the end of the longitudinal beam; the base connecting plate is connected to the front anti-collision beam structure in a detachable manner.

[0018] The advantages of this utility model are: This utility model discloses an installation end plate for installing a crash beam and a crash beam assembly having the installation end plate.

[0019] The mounting end plate for installing the anti-collision beam disclosed in this utility model is mainly used for connecting the front anti-collision beam structure at the end of the longitudinal beam.
