Embodiment Construction

[0013] see figure 1 , the front frame skeleton structure is composed of the left and right longitudinal beam welding assemblies 3 and 4, the front collision beam welding assembly 1, the front beam welding assembly 2 and the front wall support beam welding assembly 5 to form a complete receiving force frame. see Figure 4 It can be seen that the left and right longitudinal beam welding assemblies 3 and 4 are "Z"-shaped structures made of high-strength steel plates. Depend on figure 2 and image 3 It can be seen that the front collision beam welding assembly 1 and the front cross beam welding assembly 2 adopt a closed section, and the front cross beam welding assembly 2 is composed of a front cross beam 31 and a front cross beam left connector 32 and a front cross beam right connector 33 welded at both ends. . For the structure of the welding assembly 5 of the front wall support beam, see Figure 5 , the front panel support beam 51 and the front panel front panel strength...

Abstract

The invention relates to a micro car front framework structure, composing a complete bearing frame by left and right carling welded assembly and multiple beam welded assembly, where the left and right carling welded assembly is of a 'Z'-shaped structure, and the multiple beam weled assembly comprises front collision beam welded assembly, front beam welded assembly and front wallboard support beam welded assembly, the front collision beam welded assembly is arranged in front of the front beam welded assembly and connected by bolt, the front collision beam welded assembly and the front beam welded assembly both adopt closed section, and the front wallboard support beam welded assembly comprises front wallboard support beams and front wallboard front plate reinforcing beams by welding. And it has better intensity and rigidity, and strong anti-head on collision and anti-side collision and antitorque abilities, and the main parts adopt high intensity steel plate, the structural section size is smaller, able to save materials and room, and prolong automobile's service life.

Description

technical field [0001] The invention belongs to the automobile body structure technology, and in particular relates to a skeleton structure of a car. Background technique [0002] In order to ensure the rigidity and strength of the car body and to improve the collision performance of the car, the existing car front frame skeleton structure has a large cross-sectional size and thick steel plates, which increases the weight and material cost of the car body assembly, which is not conducive to mini cars. use. Contents of the invention [0003] The invention provides a car front frame skeleton structure to meet the needs of the mini car body structure and solve the above-mentioned problems existing in the existing structure. [0004] The technical solution of the present invention is as follows: the front frame skeleton structure is the main bearing part of the vehicle body, should have sufficient rigidity and strength, and have strong anti-collision and anti-torsion performa...
