Embodiment 1

[0055] see figure 1 – Figure 4 , a birdcage body frame structure, comprising a front wall assembly A, a rear wall assembly B and a top cover assembly C, the two ends of the top cover assembly C are connected to the front wall assembly A, the rear wall assembly The upper end of B is connected, the lower ends of the front wall assembly A and the rear wall assembly B are connected with the bottom frame assembly E, and the side part of the bottom frame assembly E is connected with the top cover assembly C through the side wall assembly D. The top cover assembly C includes a plurality of parallel top beams 51, and the side wall assembly D includes a plurality of side wall vertical beams 52 parallel to each other; connected, the bottom of the side girder 52 is fixedly connected with the skirt assembly F, and the top beam 51 and the side girder 52 are integrated; the vehicle body skeleton structure also includes a plurality of rectangular side window frames 4, each Rectangular sid...

Embodiment 2

[0057] see Figure 5 – Figure 9 , embodiment 2 is basically the same as embodiment 1, its difference is:

[0058] The side wall assembly D is provided with under-window reinforcing stringers 71 and middle reinforcing stringers 72, the upper side of the under-window reinforcing stringers 71 is fixedly connected with the side window lower stringers 45, and the under-window reinforcing stringers 71 The lower side of the lower side of the window is fixedly connected with the embedded stringer 61 under the window, and the upper side and the lower side of the middle reinforced stringer 72 are respectively fixedly connected with the two middle embedded stringers 62; the skirt assembly F is provided with The skirt reinforcement stringer 73, the upper side of the skirt reinforcement stringer 73 is fixedly connected with the skirt embedded stringer 63, and the lower side of the skirt reinforcement stringer 73 is fixedly connected with the skirt connection stringer 32; The rear wall a...

Abstract

A birdcage type vehicle body skeleton structure comprises a front wall assembly, a rear wall assembly and a top cover assembly, wherein the two ends of the top cover assembly are connected with the upper ends of the front wall assembly and the rear wall assembly; the lower ends of the front wall assembly and the rear wall assembly are connected with a chassis assembly; the side part of the chassis assembly is connected with the top cover assembly through a side wall assembly; the top cover assembly comprises a plurality of parallel top cross beams; the side wall assembly comprises a plurality of parallel side wall vertical beams; two ends of the top cross beams are connected with tops of the side wall vertical beams, and the top cross beams and the side wall vertical beams form an integrated structure; a plurality of embedded beams are arranged on the side wall assembly and the rear wall assembly; and stiffening beams running through the periphery of a vehicle body are correspondingly arranged on the embedded beams. According to the design, the birdcage type vehicle body skeleton structure is firmer in connection and strong in impact resistance, and can disperse the impact force, reduces the deformation degree of the vehicle body and provides more survival space for passengers when being collided.

Description

technical field [0001] The invention relates to an automobile frame structure, in particular to a birdcage type body frame structure, which is particularly suitable for enhancing the firmness and impact resistance of the body frame. Background technique [0002] According to the most stringent school bus regulations in China, it is only required that the top beam, column and floor beam on the same cross section should form a closed ring structure, and the body column from the upper side beam of the side window to the floor beam should adopt an integral structure. The middle shall not be connected by tailor welding. The closed-loop structure of the car body, because the roof and the side wall structure still do not constitute a whole, and the longitudinal connection of the car body is also welded by segmented longitudinal beams and beams (pillars), which may cause the roof to be completely sheared in a car accident Detachment, or the case where the body deforms and invades t...
