Description

Technical Field

[0001] This utility model relates to the field of vehicle equipment technology, and more specifically, to a welded assembly of the inner plate of a rear anti-collision beam. Background Technology

[0002] The rear bumper inner panel is a structural component inside the rear bumper of a car, usually made of high-strength steel. It is used to absorb and disperse collision energy during a collision, protecting the safety of passengers inside the vehicle. As part of the car's passive safety system, the design and installation of the rear bumper inner panel are carefully considered to ensure that it can function effectively in the event of a collision. During a collision, the rear bumper inner panel first absorbs the impact force, and then transfers the impact force to other parts of the vehicle body through its own structural deformation, thereby reducing damage to the main structure of the vehicle body and protecting the passengers inside from injury.

[0003] For example, Chinese Patent Publication: A welded assembly of a rear bumper beam for a passenger vehicle, application number: CN201921151866.7, includes a rear bumper beam with an I-shaped cross-section. A protective plate is provided on the front side of the rear bumper beam, and several springs are fixed between the protective plate and the rear bumper beam. One end of the spring is welded into a groove A on the side of the rear bumper beam, and the other end of the spring is welded to the inner side of the protective plate. Two energy-absorbing boxes are respectively fixed to the two ends of the rear side of the rear bumper beam by welding. One end of the energy-absorbing box is fixed into a groove B on the other side of the rear bumper beam, and the other end of the energy-absorbing box is fixed to a mounting plate. Several bolts are provided on the mounting plate and fixed into a corresponding number of threaded through holes. This application utilizes the deformation of the protective plate and the elastic potential energy of the springs to mitigate the impact force generated during a collision, which can more effectively reduce the damage to the main body of the vehicle and the occupants when rear-ended. At the same time, the use of an I-shaped rear bumper beam reduces its own weight and improves the side bending resistance.

[0004] However, among the above-mentioned technical solutions, the traditional rear bumper beam inner plate welding assembly has many shortcomings in terms of installation connection, assembly efficiency, maintenance convenience and collision safety. Specifically, the traditional connection method is often complex and inefficient, making it difficult to achieve rapid alignment and positioning. In addition, the traditional design has limited effect in absorbing collision energy and reducing vibration, and fails to fully realize the potential of the rear bumper beam in improving vehicle safety performance. Utility Model Content

[0005] The main objective of this invention is to provide a welded assembly for the inner plate of a rear bumper beam, which can effectively solve the many shortcomings of traditional welded assemblies for the inner plate of rear bumper beams in terms of installation and connection, assembly efficiency, maintenance convenience, and collision safety. Specifically, traditional connection methods are often complex and inefficient, making it difficult to achieve rapid alignment and positioning. In addition, traditional designs have limited effectiveness in absorbing collision energy and reducing vibration, failing to fully realize the potential of the rear bumper beam in improving vehicle safety performance.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rear anti-collision beam inner plate welding assembly, including an anti-collision beam inner plate, wherein a flange and several reinforcing ribs are fixedly provided on the anti-collision beam inner plate, several shock-absorbing pads are fixedly provided on the flange, two reinforcing beams are fixedly provided on one side of the flange, several connecting ears and mounting grooves are provided between the two reinforcing beams, and a first connecting hole is provided in the mounting groove.

[0007] Preferably, the reinforcing beam is fixedly installed on the inner plate of the anti-collision beam.

[0008] Preferably, the connecting ear includes a connecting ear body, the connecting ear body is provided with two mounting feet, the mounting feet are provided with threaded holes, and connecting bolts are provided in the threaded holes.

[0009] Preferably, a second connecting hole is provided on the side of the connecting ear body away from the mounting foot, and guide blocks are provided on both sides of the connecting ear body.

[0010] Preferably, the connecting ear body is fixedly connected to the mounting foot.

[0011] Preferably, the mounting feet are fixedly connected to the inner plate of the anti-collision beam by connecting bolts, and the guide block is fixedly connected to the main body of the connecting ear.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) When this utility model is used, the inner plate of the anti-collision beam is installed and connected through the connecting ear and the first connecting hole, and the connecting ear is aligned and positioned by the guide block to improve the assembly efficiency. Then, the connecting ear is installed and connected through the second connecting hole. When it is necessary to replace or repair the inner plate of the anti-collision beam or the connecting ear separately, the connecting bolt is rotated to release the fixed connection between the main body of the connecting ear and the inner plate of the anti-collision beam, so that the inner plate of the anti-collision beam or the connecting ear can be replaced or repaired separately. This facilitates the replacement or repair of the inner plate of the anti-collision beam or the connecting ear. The shock-absorbing pad is used to reduce the vibration generated by the collision and improve safety. The reinforcing beam fixedly connected to the flange further improves the structural rigidity and strength of the assembly and enhances the collision safety. Attached Figure Description

[0021] When it is necessary to install and connect the inner plate 1 of the anti-collision beam using the connecting lug 5, the connecting lug 5 is aligned and positioned by the guide block 506 to improve assembly efficiency. Then, the connecting lug 5 is installed and connected through the second connecting hole 505. When it is necessary to replace or repair the inner plate 1 of the anti-collision beam or the connecting lug 5 separately, the connecting bolt 504 is rotated to release the fixed connection between the connecting lug body 501 and the inner plate 1 of the anti-collision beam, so that the inner plate 1 of the anti-collision beam or the connecting lug 5 can be replaced or repaired separately, which is convenient for replacing or repairing the inner plate 1 of the anti-collision beam or the connecting lug 5.
