Description

Technical Field

[0001] The utility model relates to the technical field of front cross beams, in particular to a front cross beam buffer structure. Background Art

[0002] The front crossbeam of a car is the first crossbeam behind the front bumper. The longitudinal beam is usually stamped from low-alloy steel plates. The cross-section is generally groove-shaped, and some are Z-shaped or box-shaped. Depending on the different types of cars and the requirements of the structural layout, the longitudinal beam can be curved in the horizontal plane or in the longitudinal plane, as well as with equal or non-equal cross-sections. The function of the front crossbeam of a car is to ensure the torsional stiffness of the frame and withstand longitudinal loads, and to support key components of the vehicle. The crossbeam is connected by riveting, so that it has sufficient strength and rigidity to withstand the load of the car and the impact from the wheels.

The front cross beam of the vehicle body is U-shaped as a whole, and mainly includes a main beam and a first connecting member and a second connecting member arranged at both ends of the main beam. The front cross beam of the vehicle body is connected to the vehicle body through the first connecting member and the second connecting member. A bumper bracket is also arranged on the main beam for supporting and connecting the bumper. Since the first connecting member and the second connecting member are detachably connected to the main beam respectively, assembly is relatively convenient; and the overall structure of the front cross beam of the vehicle body is relatively simple, thereby reducing the cost of the front cross beam of the vehicle body. The above-mentioned automobile includes a vehicle body and the above-mentioned front cross beam of the vehicle body. Since the automobile adopts the above-mentioned front cross beam of the vehicle body, the overall cost of the automobile is reduced, and replacement and maintenance are relatively convenient.

In order to ensure the overall cost of the car is reduced and replacement and maintenance are convenient, the above design causes the front cross beam of the device to be easily deformed when facing external impact due to the lack of buffer components, which greatly reduces the life safety of the driver and the safety factor of the vehicle.
