Among them, the rear crossbeam of the car's front seats plays a vital role in the sheet metal parts of the car body. The most intuitive function is to fix the front seats of the vehicle. On the other hand, in the side collision safety protection of the whole vehicle, the rear crossbeam of the car's front seats also plays a role in improving the side structural stiffness of the car body and effectively transmitting the side collision load.

[0026] See also Figure 1-Figure 6 As shown, the utility model is a cross beam structure of a front seat of an automobile, comprising a main body 1, an energy absorbing tube 6 and a buffer fixed base 18, first fixing plates 14 are fixedly installed at both ends of the inner wall of the main body 1, a hydraulic buffer 13 is fixedly installed on the outer side of the first fixing plate 14, a second fixing plate 17 is fixedly installed on one end face of the hydraulic buffer 13, an assembly groove 16 is provided in the buffer fixed base 18, a through hole is opened on one surface of the assembly groove 16, a first hexagonal bolt 3 is installed in the through hole, and the first hexagonal bolt 3 is threadedly connected to the first fixing plate 14, by arranging the hydraulic buffer 13 and the buffer fixed base 18, when the side of the automobile is hit, the hydraulic buffer 13 can absorb a part of the buffering force, effectively avoid the impact force directly acting on the cross beam, can effectively protect the people in the car, and has strong practicality.
[0027] Among them, a V-shaped cross plate 12 is installed on the inner wall of the main body 1, and both ends of the V-shaped cross plate 12 are fixedly connected to the first fixing plate 14. Fixing holes 11 are evenly opened on the upper surface of the main body 1, and a second hexagonal bolt 7 is installed in the fixing hole 11. The second hexagonal bolt 7 passes through the V-shaped cross plate 12, and a nut 15 is threadedly installed at the lower end. Both ends of the V-shaped cross plate 12 are fixedly connected to the side of the inner wall of the main body 1. By setting the V-shaped cross plate 12, most of the current cross beams are designed to be H-shaped or "J"-shaped to improve the strength of the cross beam. However, when the force has a certain angle, the H-shaped or "J"-shaped cross beam is prone to bending. The V-shaped cross plate 12 not only provides two cross plates for reinforcement in the horizontal direction, but also acts as a reinforcing rib on both sides of the main body 1 to improve the bending resistance, which can effectively improve the structural strength of the beam and further improve the practicality.
[0028] Among them, a mounting groove 2 is opened on one surface of the energy absorbing tube 6, and the energy absorbing tube 6 is fixedly connected to the buffer fixed base 18. By setting the energy absorbing tube 6, energy can be absorbed at the first time when the vehicle contacts the impact, thereby reducing the impact force of contacting the crossbeam and ensuring the safety of passengers.
[0029] Among them, the sides of the inner wall of the main body 1 at both ends are provided with sliding grooves 8, and a slider 5 is fixedly installed on one side of the buffer fixed base 18. The slider 5 is slidably installed in the sliding groove 8. By setting the slider 5 and the sliding groove 8, the buffer fixed base 18 can slide conveniently to squeeze and buffer the hydraulic buffer 13.
[0030] A connecting plate 10 is fixedly mounted on one surface of the main body 1 , and a plurality of mounting holes 9 are evenly provided on the upper surface of the connecting plate 10 . The plurality of mounting holes 9 facilitate the connection, installation and fixation of the side of the connecting plate 10 .
[0031] The lower surface of the connecting plate 10 is symmetrically fixed with a limiting square steel pipe 4. By providing the limiting square steel pipe 4, the stability of the fixation between the main body 1 and the vehicle floor can be ensured.
[0032] The first hexagonal bolt 3 is located in the mounting groove 2 , and the connection and fixation of the energy absorbing block 6 are facilitated by providing the first hexagonal bolt 3 .
[0033] Example: Figure 1-Figure 6As shown, the working principle of a front seat crossbeam structure of an automobile of the utility model is as follows: a hydraulic buffer 13 is installed between the main body 1 and the buffer fixed base 18, and the buffer fixed base 18 is connected to the energy absorbing tube 6. When subjected to a lateral impact, the energy absorbing tube 6 and the hydraulic buffer 13 absorb a part of the impact to prevent the impact from directly acting on the crossbeam. The buffering effect is good and can effectively protect the occupants of the vehicle. The V-shaped cross plate 12 is fixed to the main body 1 by the second hexagonal bolt 7, and then the two ends of the V-shaped cross plate 12 are welded and fixed to the two side surfaces of the inner wall of the main body 1. Not only two transverse reinforcing ribs are formed in the crossbeam, but also the reinforcing ribs are played between the two side surfaces and the top surface of the main body 1, which can effectively improve the bending resistance of the crossbeam and avoid bending caused by impact at a certain angle, thereby ensuring the safety of passengers.
