The side reinforcing piece 3 is located the bight position of automobile body side, through the optimal design of following structure, can play the coordination effect of strengthening to the bight region that receives the impact easily, strengthen the anticollision and the deformation resistance ability of bumper, improve the security performance of car operation.
The middle of the beam main body 1 is a straight-line-shaped main beam 11, two ends of the main beam 11 are respectively and sequentially extended with an inclined beam 12 arranged obliquely upwards and an auxiliary beam 13 arranged horizontally, the beam mounting frame 2 is fixed on the auxiliary beam 13, and the buffer frame 4 is fixed on the main beam 11.
Further, the cross section of the beam main body 1 is in a T shape, the upper plane of the T shape faces the tail of the automobile, and a through hole which can be matched with the T-shaped cross section in a sleeved mode is formed in the beam mounting frame 2, so that the beam main body 1 can be fixed on the beam mounting frame 2 in a sleeved mode. The T-shaped section is arranged, so that the fixation of the beam main body 1 and the beam mounting frame 2 is more stable, and the structure relaxation caused by frequent vibration in the automobile movement process is avoided; the orientation design of the T-shaped section enables the beam main body 1 to support the bumper from the plane, the supporting contact surface is enlarged, and the supporting effect is ensured.
The width of the plane of the frame body of the beam mounting frame 2 is firstly gradually decreased gradually and then rapidly decreased gradually along with the extending direction, and a plurality of mounting holes 21 are formed in the end portion of the beam mounting frame 2 and are used for being detachably connected with a frame.
Further, the end part of the beam mounting frame 2 is further provided with an auxiliary mounting block 22, and the auxiliary mounting block 22 is provided with an auxiliary mounting hole 23 perpendicular to the frame body plane of the beam mounting frame 2 for auxiliary mounting of the beam mounting frame 2. The auxiliary positioning of the beam mounting frame 2 can be better performed by the control of the auxiliary mounting block 22, so that the beam mounting frame 2 can be integrally positioned with the frame from different mounting directions, and the mounting reliability is improved.
Further, the center of the plane of the frame body of the beam mounting frame 2 is provided with a unloading hole 24, and the unloading hole 24 can reduce the total weight of the beam mounting frame 2 on one hand and can play a role in unloading and damping on the other hand.
Wherein the buffer frame 4 comprises two comb-shaped connecting blocks 41 respectively fixed on the beam main body 1 and the side reinforcing piece 3, the rows of the comb-shaped connecting blocks 41 are staggered and intersected with the end parts, and the intersected parts are fixed by traversing screws 42. The setting of buffer frame 4 can play shock attenuation cushioning effect to crossbeam main part 1 and side reinforcement 3, because the bumper is installed on side reinforcement 3, will be to the instantaneous extremely strong impulsive force of side reinforcement 3 transmission when the collision, rigid connection causes great shock to damage to crossbeam main part 1 easily, and buffer frame 4 can play the cushioning effect to instantaneous impulsive force extremely well, protects crossbeam main part 1, improves the buffering toughness of whole installing support structure.
Further, an auxiliary stay bar 5 and an inclined stay bar 6 are further arranged between the beam main body 1 and the side reinforcing member 3, two ends of the auxiliary stay bar 5 are respectively connected to the end parts of the main beam 11 and the side reinforcing member 3 of the beam main body 1, and two ends of the inclined stay bar 6 are respectively connected to the middle parts of the inclined beam 12 and the side reinforcing member 3 of the beam main body 1.

The vertical surface portion 34 enables planar contact of the bumper to be integrally supported, and improves support strength and reliability by increasing the planar contact area. In addition, since the corners of the vehicle are more susceptible to impact and the deformation stresses to which they are subjected are more concentrated, the arcuate reinforcing section 32 is capable of effectively reinforcing the bumper at the corners of the vehicle body, matching the vertical surface portions 34 allows the supporting ability of the corners and the elastic recovery ability of the bumper to be further enhanced.
Further, the bottom inner side of the side reinforcement 3 is provided with a reinforcing rib 35 near the arc-shaped reinforcing section 32, one first supporting surface 351 of the reinforcing rib 35 is angular and perpendicular to the upper plane portion 33 and the vertical plane portion 34, respectively, and the other two second supporting surfaces 352 are perpendicular to the first supporting surface 351 and extend to the vertical plane portion 34 of the arc-shaped reinforcing section 32. The provision of the reinforcing ribs 35 can prevent the vertical surface portion 34 of the arc-shaped reinforcing section 32 from being damaged and deformed by external force.
Further, the side reinforcement 3 has an auxiliary supporting surface 36 extending upwardly from the upper planar portion 33 of the arcuate reinforcement 32.
