Embodiment Construction

[0064] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0065] The following will refer to Figure 1-Figure 23 The vehicle body 10000 of the embodiment of the present invention will be described in detail in conjunction with the embodiments.

[0066] The vehicle body 10000 according to the embodiment of the present invention may include: two A-pillars 100, a front anti-collision beam 200, two front longitudinal beams 300, a dash panel 400, a dash upper cross member 402, a dash lower vertical beam 403 and two The front floor longitudinal beam 500 , of course, the vehicle body 10000 may also include other components, for example, the upper side rail 600 , the door sill beam 800 and the rear floor longitudinal beam 900 and so on.

[0067] Such as figure 1 As shown, the front ends of the two front longitudinal beams 300 are respectively connected to the two ends o...

Abstract

The invention provides a vehicle body. The vehicle body comprises two A pillars, a front anti-collision beam, two front longitudinal beams, a front wall panel, a front wall upper cross beam and a front wall lower vertical beam, wherein the front ends of the two front longitudinal beams are connected to the two ends of the front anti-collision beam respectively, and each front longitudinal beam isconnected with the A pillar on the same side through a plurality of force transfer channels; the rear ends of the two front longitudinal beams are connected to the front wall panel, the lower portionof the front wall panel is provided with a front wall panel middle channel, and the front wall panel is connected with the two A pillars; the front wall upper cross beam is arranged on the upper portion of the front wall panel; the upper end of the front wall lower vertical beam is connected to the front wall upper cross beam, and the lower end of the front wall lower vertical beam extends to thefront wall panel middle channel. By arranging the force transfer channels, stress can be efficiently and rapidly absorbed and decomposed, and collision force transferred to the rear part can be effectively dispersed; thus, the invasion amount of the front wall panel can be greatly reduced, serious damage to the vehicle body can be avoided, and sufficient living space in a passenger compartment canbe better guranateed.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle body. Background technique [0002] With the continuous progress of society, people pay more and more attention to the safety of automobile collisions. More and more automobiles have strengthened the structure of the front wall assembly, and designed energy-absorbing and collapse structures for the longitudinal beams, so as to improve the safety performance of automobiles. Although it can reduce the intrusion of the cowl after the collision to a certain extent and improve the living space to a limited extent, it still cannot efficiently decompose and transmit the force, and has not fundamentally solved the problem of single force transmission channel and low force transmission efficiency. Contents of the invention [0003] In view of this, the present invention aims to provide a vehicle body to solve the problems of single force transmission channel and low force tra...
