[0002] With the development of society, automobiles are widely used in people's daily lives. The front and rear of automobiles are usually equipped with anti-collision beams. The beam of the anti-collision beam is the main energy-absorbing and anti-collision component. When a vehicle is involved in a frontal collision, the anti-collision beam is the first line of defense. It can absorb and disperse most of the impact force and effectively reduce the energy generated by the collision from being transferred to the passenger compartment. The anti-collision beam absorbs and disperses the impact energy through the energy-absorbing box. However, after the anti-collision beam is fixed by bolts, the buffering effect of the fixed structure on the anti-collision beam still needs to be further improved.

[0003] Therefore, it is necessary to propose a fixed structure for automotive anti-collision beams. Utility Model Content

[0004] The purpose of this invention is to provide a fixing structure for automotive anti-collision beams to solve the problems mentioned in the background art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 ;

[0023] The automotive anti-collision beam fixing structure includes an anti-collision beam 1, with energy-absorbing boxes 11 welded to the back of both ends of the anti-collision beam 1. The energy-absorbing boxes 11 undergo plastic deformation during a collision through a pre-designed pleated structure, effectively absorbing and dispersing impact energy. A connecting plate 12 is welded to the rear end of the energy-absorbing box 11, which is used to support the anti-collision beam 1 to be installed at the front end of the vehicle frame. Connecting structures 2 are provided at both ends of the anti-collision beam 1, which can increase the buffering capacity of the automotive anti-collision beam.

[0024] The connecting structure 2 includes a connecting seat 21, a first buffer plate 22, a second buffer plate 23, and a buffer assembly 29. The connecting seat 21 is snapped onto the rear end of the connecting plate 12. The connecting seat 21 has a groove inside for engaging the connecting plate 12. The connecting seat 21 is first installed on the frame with bolts. The connecting seat 21 is used to support the installation of the first buffer plate 22 and the second buffer plate 23. The connecting plate 12 is then snapped into the connecting seat 21 and connected to the frame again with bolts. The end of the bolt installed on the connecting seat 21 in the first installation penetrates the inner wall of the connecting plate 12, without affecting the installation of the connecting plate 12, thereby fixing the connecting plate 12 to the front end of the frame. The first buffer plate 22... The first buffer plate 22 and the second buffer plate 23 are fixedly installed on one side of the connecting seat 21, and the front ends of the first buffer plate 22 and the second buffer plate 23 are respectively attached to the rear end of the anti-collision beam 1. The first buffer plate 22 and the second buffer plate 23 are respectively used to absorb and disperse the impact energy of the anti-collision beam 1, and play a buffering role. The bottom of the first buffer plate 22 is fixedly provided with a first support plate 221, and the bottom of the second buffer plate 23 is fixedly provided with a second support plate 231. When the anti-collision beam 1 is installed, the first support plate 221 and the second support plate 231 are first supported on the bottom of the anti-collision beam 1, which improves the portability of the anti-collision beam 1 during installation.

[0025] Furthermore, the buffer assembly 29 is connected to the rear end of the anti-collision beam 1. The buffer assembly 29 includes a third buffer plate 26 and a mounting bracket 28. The mounting bracket 28 is fixedly installed at both ends of the third buffer plate 26. The third buffer plate 26 is installed on the anti-collision beam 1 through the mounting bracket 28. The second buffer plate 23, the second support plate 231, and the anti-collision beam 1 are all snapped into the inner side of the mounting bracket 28 and connected and fixed by mounting bolts to increase stability. A buffer frame 27 is welded to the inner side of the third buffer plate 26. The buffer frame 27 is corrugated. The front end of the buffer frame 27 fits against the rear end of the anti-collision beam 1. Plate 26 and buffer frame 27 are also used to absorb and disperse the impact energy of anti-collision beam 1 and increase the impact buffering effect. The end of the second buffer plate 23 is welded with a clamping plate 24, and the other end of the clamping plate 24 is attached to the inner side of the third buffer plate 26 so that the impact force received by the second buffer plate 23 is dispersed to the third buffer plate 26. The inner wall of the connecting seat 21 is provided with a first connecting hole 25, which is used to install bolts. The inner walls of the connecting plate 12 and the connecting seat 21 are both provided with a second connecting hole 251, which is used to install bolts on the connecting plate 12 and the connecting seat 21.

[0026] The working principle of this utility model is as follows: Bolts are installed in the first connecting hole 25 of the connecting seat 21. The connecting seat 21 is first installed on the front end of the vehicle frame by bolts. The first buffer plate 22 and the second buffer plate 23 are fixedly installed on both sides of the connecting seat 21 respectively. The first support plate 221 is fixedly set at the bottom of the first buffer plate 22, and the second support plate 231 is fixedly set at the bottom of the second buffer plate 23. The retaining seats 28 at both ends of the third buffer plate 26 are then snapped onto the second buffer plate 23 and the second support plate 231. The connecting plate 12 is snapped into the inside of the connecting seat 21. The first support plate 221 and the second support plate 231 are respectively supported at the bottom of the anti-collision beam 1, improving the portability of the anti-collision beam 1 during installation. Bolts are installed in the second connecting hole 251 on the connecting plate 12 and the connecting seat 21. The connecting plate 12 is snapped into the connecting seat 21. The bracket 21 is connected to the vehicle frame again by bolts. The upper end of the bracket 28 is connected and fixed to the anti-collision beam 1 and the second buffer plate 23 by bolts. The lower end of the bracket 28 is connected and fixed to the second support plate 231 and the anti-collision beam 1 by bolts. The first buffer plate 22 and the second buffer plate 23 are used to absorb and disperse the impact energy of the anti-collision beam 1, thus playing a buffering role. The other end of the bracket 24 is attached to the inner side of the third buffer plate 26, so that the impact force received by the second buffer plate 23 is dispersed to the third buffer plate 26. A buffer frame 27 is welded to the inner side of the third buffer plate 26. The buffer frame 27 is corrugated. The front end of the buffer frame 27 is attached to the rear end of the anti-collision beam 1. The third buffer plate 26 and the buffer frame 27 are also used to absorb and disperse the impact energy of the anti-collision beam 1, thus increasing the impact buffering effect.

[0027] In summary, by adding a connecting seat 21 to the rear end of the car anti-collision beam, and installing a first buffer plate 22 and a second buffer plate 23 on the connecting seat 21, which are attached to the rear end of the anti-collision beam 1, the impact energy of the anti-collision beam 1 is absorbed and dispersed, thus playing a buffering role. By installing a third buffer plate 26 and a corrugated buffer frame 27 in the middle of the rear end of the anti-collision beam 1, the impact energy of the anti-collision beam 1 is also absorbed and dispersed, thereby increasing the buffering effect of the car anti-collision beam.
