Problems solved by technology
[0002] At present, most of the rear seat belt installation points of commercial vehicles on the market are on the floor, and the seat belts are fixed on the floor by bolts and nuts. There is no support structure for the frame at the installation point, and the strength is weak, the mode is low, and the NVH performance is not good.

The invention discloses a three-point safety belt installation reinforcement structure. The three-point safety belt installation reinforcement structure comprises a front crossbeam, a rear crossbeam, a left longitudinal beam, a right longitudinal beam and at least two middle longitudinal beams. The front crossbeam and the rear crossbeam are parallel to each other. The left longitudinal beam, the right longitudinal beam and the middle longitudinal beams are parallel to one another. The front crossbeam and the rear crossbeam are perpendicular to the left longitudinal beam, the right longitudinal beam and the middle longitudinal beams. A closed rectangle is formed by the front crossbeam, the rear crossbeam, the left longitudinal beam and the right longitudinal beam in an enclosed mode. Two middle longitudinal beams are located between the left longitudinal beam and the right longitudinal beam. The two ends of the two middle longitudinal beams are connected with the front crossbeam and the rear crossbeam respectively. The middle longitudinal beams are provided with first safety belt installation holes. The three-point safety belt installation reinforcement structure has the beneficial effects that the middle longitudinal beams are added, so that the strength of the installation points of a safety belt is improved, the modality is improved, and the noise, vibration and harshness (NVH) property is better.
Description
technical field [0001] The invention relates to a car body, in particular to a three-point safety belt installation reinforcement structure in the car body. Background technique [0002] At present, most of the rear safety belt installation points of commercial vehicles on the market are on the floor, and the seat belts are fixed on the floor by bolts and nuts. There is no support structure for the frame at the installation point, and the strength is weak, the mode is low, and the NVH performance is not good. . Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a three-point safety belt installation strengthening structure that improves the strength of the safety belt installation point. [0004] The invention provides a three-point safety belt installation reinforcement structure, which includes a front crossbeam, a rear crossbeam, a left longitudinal beam, a right longitudinal beam and at least two middle l...
