Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle floor crossbeams, and in particular relates to a commercial vehicle floor crossbeam reinforcement structure. Background Art

[0002] Automotive plates refer to steel plates used for automobiles, which can be divided into hot-rolled steel plates, cold-rolled steel plates and coated steel plates based on the production process characteristics; from the perspective of strength, they can be divided into: ordinary steel plates (soft steel plates), low-alloy high-strength steel plates, ordinary high-strength steel plates (high-strength IF steel, BH steel, phosphorus-containing steel and IS steel, etc.) and advanced high-strength.

[0003] The existing floor cross beams are usually connected to the vehicle body only through the cross beam body. This method will result in poor overall strength of the floor. When the vehicle travels on a bumpy road, the cross beam will be subjected to a large impact force and will be the main stress point, resulting in uneven force. In the absence of a reinforcement structure, long-term use will easily cause the cross beam to bend and deform, posing certain safety hazards to the vehicle. Therefore, we propose a commercial vehicle floor cross beam reinforcement structure. Utility Model Content

[0004] The purpose of the utility model is to provide a commercial vehicle floor crossbeam reinforcement structure. By arranging an I-shaped mounting frame, the structure of the crossbeam can be strengthened, so that the force on the left and right sides is more even. At the same time, since grooves are provided on the front and back of the crossbeam, the vertical force can be dispersed, so that the crossbeam is not easy to bend and deform when in use. This solves the problem that the existing floor crossbeam is usually connected to the vehicle body only through the crossbeam body. This method will result in poor overall strength of the floor. When the vehicle travels on a bumpy road section, the crossbeam will be subjected to a large impact force and will be the main force point, thus causing the problem of uneven force.
