Description

Technical Field

[0001] This utility model relates to the technical field of automotive longitudinal beams, and particularly to a high-strength structural automotive longitudinal beam assembly. Background Technology

[0002] Increasing the strength of automotive longitudinal beams can enhance vehicle safety. Existing automotive longitudinal beams primarily rely on their own strength to resist external impacts. To improve the strength of automotive longitudinal beams, some existing vehicles have added structural elements to increase their strength.

[0003] For example, patent application number CN201720263121.4 discloses a reinforcement component for a front longitudinal beam assembly of an automobile. This patent installs a front longitudinal beam 5 and a rear longitudinal beam 3 on both sides of the automobile, and installs a buffer layer 10 on the top of the front longitudinal beam 5. A reinforcing support plate 12 and a crossbeam 11 are installed between the front longitudinal beams 5. When the automobile is hit, the front longitudinal beam 5 will be protected by the crossbeam 11 and the reinforcing support plate 12. At the same time, the adjusting plate 14 on the reinforcing support plate 12 will bend with the impact force. Meanwhile, the second buffer 13 at its bottom will buffer the reinforcing support plate 12 and reduce the impact force. At the same time, the first buffer 8 installed on the top of the front longitudinal beam 5 will buffer the front and rear impacts of the automobile, and the impact force will be reduced under the action of the buffer layer 10.

[0004] The existing patent technology increases the strength of the front longitudinal beams mainly by reinforcing the two front longitudinal beams with a reinforcing plate. However, this single reinforcing plate is quite heavy, which affects the overall weight of the car frame. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a high-strength structural automotive longitudinal beam assembly, so as to solve the problem described in the background art where the weight of the reinforcing device of the automotive front longitudinal beam has a significant impact on the weight of the vehicle frame.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength structural automotive longitudinal beam assembly, comprising...

[0007] Two front longitudinal beams;

[0008] The structure is reinforced, with each end fixedly connected to two front longitudinal beams;

[0009] The reinforcing structure includes

[0010] Two mounting plates are fixedly mounted on two front longitudinal beams respectively. Each mounting plate is provided with two limiting plates, and the mounting plate and the two limiting plates form positioning grooves with opposite openings.

[0011] Two first reinforcing plates are parallel to each other and each end has a bent portion. A positioning plate is provided on the bent portion. The positioning plate extends into the positioning groove and is fixed to the limiting plate and the mounting plate.

[0012] Several second reinforcing plates, all X-shaped, are located between two first reinforcing plates, and the ends of the second reinforcing plates are fixedly connected to the first reinforcing plates.

[0013] Preferably, the end of the second reinforcing plate has a connecting portion, which is welded to the first reinforcing plate.

[0014] Preferably, the connecting portions of two adjacent second reinforcing plates are integrated.

[0015] Preferably, the mounting plate has a first positioning hole at each end, and the front longitudinal beam has a first threaded hole at the position corresponding to the first positioning hole. The first positioning hole has a first bolt that passes through the first positioning hole and is threadedly connected to the first threaded hole.

[0016] Preferably, the limiting plate and the mounting plate have corresponding positions with second positioning holes, the front longitudinal beam has corresponding positions with first threaded holes, the positioning plate has corresponding positions with third positioning holes, and the second positioning holes and the third positioning holes have second bolts that penetrate the second positioning holes and the third positioning holes and are threadedly connected to the second threaded holes.

[0017] The beneficial effects of adopting the above technical solutions are:

[0018] This application uses a mounting plate to fix the first reinforcing plate to the front longitudinal beam. Then, the two first reinforcing plates are connected to the limiting plate and the mounting plate to fix the first reinforcing plates. A second reinforcing plate is installed between the first reinforcing plates to further increase the strength. In this application, the first and second reinforcing plates form a hollow strength support, which is lighter than the prior art. Attached Figure Description
