Description

Technical Field

[0001] The utility model relates to the field of., in particular to an anti-deformation structure of an automobile cab assembly. Background Art

[0002] The manufacturing of car bodies requires the manufacture of different parts. The parts rely on different manufacturing processes to make the use of the car body more efficient. The cab needs to be manufactured during the manufacturing of the car body. The cab can make the driving of the vehicle safer, so there are certain strength requirements for the cab.

[0003] In the prior art, a Chinese patent with publication number "CN214565732U" discloses a deformation-resistant and high-strength cab assembly. Through the arrangement of telescopic rods, anti-collision plates and buffer springs, when a vehicle collides, the anti-collision plates supported by rubber materials on the front of the main frame first play a certain buffering role, and then the anti-collision plates squeeze the buffer springs and telescopic rods. The reaction forces generated by the buffer springs and telescopic rods have a buffering effect on the anti-collision plates, thereby buffering the cab, reducing damage to the driver caused by a violent collision of the cab, and improving safety. This solves the problem that most existing cabs are made of only stamped and welded iron sheets, have a relatively simple structure, and have low anti-deformation ability and strength. Once a collision occurs, it is easy to cause harm to the driver and have poor safety.

[0004] However, the existing technology still has major deficiencies, such as:

[0005] Although the frame inside the car cab is made of a material with relatively high hardness, when the front ends of two cars collide, the front ends of the cars will still be greatly deformed. In the solution described above, this effect is achieved by utilizing the reaction force of the telescopic rod and the buffer spring. However, this method only buffers the impact force generated in the facing direction of the two car heads. When the two car heads collide in non-straight lines, the impact force cannot be fully applied to the telescopic rod and the buffer spring, which will result in partial buffering of the impact force, thereby causing greater damage to the cab.

[0031] In this embodiment, by installing a stabilizing frame 3 that is identical to the frame 1 on the outer side of the frame 1 in the vehicle cab, the bending resistance of the vehicle cab can be enhanced. At the same time, the stabilizing frame 3 on the stabilizing frame 3 is used to enhance the strength and rigidity of the stabilizing frame 3, so that when the vehicle cab is subjected to a certain degree of impact, the vehicle cab will not be greatly deformed, thereby effectively improving the impact resistance of the vehicle cab assembly.

[0032] Embodiment 2:

[0033] A pressure-resistant component is arranged on the stabilizing frame 3, and the impact force of the front of the automobile when being hit is reduced by the pressure-resistant component. The pressure-resistant component is composed of a buffer component 1, a buffer component 2 and a buffer plate 5. The buffer component 1 includes a mounting groove 6, and a damper 7 and a first buffer spring 8 are fixedly installed in the mounting groove 6. The first buffer spring 8 is located on the outside of the damper 7, and the output end of the damper 7 is installed on the buffer plate 5. The end of the first buffer spring 8 away from the mounting groove 6 is installed on the buffer plate 5.

[0036] Working principle:

[0037] By installing a stabilizing frame 3 identical to the frame 1 on the outside of the frame 1 in the vehicle cab, the bending resistance of the vehicle cab can be enhanced. At the same time, the strength and rigidity of the stabilizing frame 3 are enhanced by using the stabilizing frame 3 on the stabilizing frame 3, so that when the vehicle cab is subjected to a certain degree of impact, the vehicle cab will not be greatly deformed, thereby effectively improving the impact resistance of the vehicle cab assembly.

[0038] When the front ends of two cars collide, the impact will act on the buffer plate 5, and the buffer plate 5 will squeeze the first buffer spring 8 and the damper 7. The reaction force generated by the first buffer spring 8 and the damper 7 will buffer the impact force. While squeezing the first buffer spring 8 and the damper 7, the buffer plate 5 will drive the sliding block 13 to slide on the sliding rod 12 through the fixing frame 10 and the stabilizing rod 14. The sliding block 13 will squeeze the second buffer spring 15. The reaction force generated by the second buffer spring 15 will buffer the impact force acting on the buffer plate 5 in other directions, thereby reducing the damage to the driver caused by a violent collision of the cab, and effectively improving the practicality of the automobile cab assembly.

[0039] When the buffer plate 5 changes position, the buffer plate 5 will slide in the limiting groove through the limiting rod, so that the buffer plate 5 will not be offset.
