Abstract
The invention provides a battery mounting and fixing structure of a purely electric automobile, which comprises a rear floor front cross beam assembly, a rear floor rear cross beam, left and right rear longitudinal beams and rear longitudinal beam battery left and right mounting frames. The rear floor front cross beam assembly is mounted on the front ends of the left and right rear longitudinal beams by bolts and connected with a rear floor; the two ends of the rear floor rear cross beam are arranged on the rear ends of the left and right rear longitudinal beams by bolts and connected with the rear floor; and the rear longitudinal beam battery left and right mounting frames are welded with the middle parts of the let and right rear longitudinal beams respectively. The rear floor front cross beam assembly, the rear floor rear cross beam and the rear longitudinal beam battery left and right mounting frames are provided with battery mounting holes respectively. The fixing structure is a frame structure, can reasonably bear the weight of a battery pack and optimize the torsional rigidity of the vehicle body, and is excellent in assembly process and convenient in mounting and detachment.
Description
Technical field
The present invention relates to automotive body structure, be specifically related to car body sheet metal component structure.
Background technology
Along with the growing tension of the energy and people pay attention to day by day to environmental protection, see for a long time pure electronic will be the main direction of auto trade, but power brick is an acid test to traditional vehicle body, the power brick of hundreds of kilogram can not directly be contained in (see figure 1) on floor 2, original back, left back longeron 1 and the right back longeron 3, needs to increase a kind of back floor frame structure and battery is installed, is optimized body stiffness, intensity.
Summary of the invention
The purpose of this invention is to provide a kind of pure electric automobile battery mount fixing structure, it can satisfy the battery installation requirement on the one hand, optimize body torsional rigdity; Assembly process process is good on the other hand, convenient disassembly is installed not influencing under the original structure assembly technology prerequisite.
Technical scheme of the present invention is as follows:
A kind of pure electric automobile battery mount fixing structure comprises floor, back front cross rail assembly, floor, back after cross member, left back longeron, right back longeron, floor side member battery left installation bracket and floor side member battery right mounting bracket.Back floor front cross rail assembly is installed in left back longeron and right back longeron front end, and is connected with the floor, back simultaneously; After cross member two ends, back floor are installed in left back longeron and right back longeron rear end, also are connected with the floor, back simultaneously; Floor side member battery left installation bracket and floor side member battery right mounting bracket are welded on left back longeron and right back longeron middle part respectively.On floor, back front cross rail assembly, floor, back after cross member, floor side member battery left installation bracket and floor side member battery right mounting bracket, be provided with the battery mounting hole.
The said fixing structure is a framed structure, power brick is mounted thereon, the weight of power brick can be passed on the floor side member, and form force structure by whole framework, can optimize the torsional stiffness of vehicle body, improve power brick directly to be contained in material thick installation reliability is poor, bus body strength is poor, problems of crack less than causing on 1 millimeter back floor, left back longeron and the right back longeron.
The wherein back floor front cross rail common section bar that can have drawn from, and the two ends of floor, back front cross rail after cross member all adopts bolt connecting mode with chassis runner, and the connection structure assembly process process is good like this, installation, convenient disassembly.
Description of drawings
Fig. 1 is the structural representation that the power brick part is installed on the floor behind original vehicle body.
Fig. 2 is the scheme drawing of the mount fixing structure that proposes of the present invention.
Fig. 3 is the constitution diagram of installing after the power brick;
Fig. 4 is the left view of Fig. 3.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Referring to Fig. 2, provided a kind of battery mount fixing structure of automobile among the figure, it comprises the back floor front cross rail assembly of being made up of a front cross rail left side, floor, back attaching parts 4, the right attaching parts 6 of floor, back front cross rail and floor, back front cross rail 5, left back longeron 3, floor side member battery left installation bracket 9, right back longeron 1, floor side member battery right mounting bracket 10 and floor, back after cross member 8, they are connected to form framed structure.
Wherein, back floor front cross rail 5 is directly formed by the section bar intercepting and the boring of square-section, technology is simple, offer three battery mounting hole 11 (see figure 3)s in the above, it is welded into floor, back front cross rail assembly with a front cross rail left side, floor, back attaching parts 4, floor, the back right attaching parts 6 of front cross rail, back floor front cross rail assembly adopts bolt connecting mode to be connected with right back longeron 1 with the left back longeron 3 that is welded on 2 left and right sides, floor, back again, and also is connected with floor 2, back simultaneously.
Also offer three battery mounting hole 11 (see figure 3)s on floor, back after cross member 8, its two ends also adopt bolt connecting mode to be connected with right back longeron 1 with left back longeron 3, and also are connected with floor 2, back simultaneously.
On floor side member battery left installation bracket 9, offer a battery mounting hole 11, and it is welded on the middle part of left back longeron 3.On floor side member battery right mounting bracket 10, offer a battery mounting hole 11, it is welded on the middle part of right back longeron 1.
Referring to Fig. 3, Fig. 4, carry six mounting brackets on the power brick 7, adopt bolt connecting mode to be connected on six battery mounting holes 11 of floor, back front cross rail assembly, floor side member battery left installation bracket 9, floor side member battery right mounting bracket 10 and floor, back after cross member 8 respectively.
The characteristics of whole framework are: form stressed frame structure, with the weight transmitting of power brick to floor side member, optimized the torsional rigidity of vehicle body, the reliability height, and installation aspect, whole process can increase operation in original production line back again and carry out general assembly, does not affect original production technology, and easy installation and removal.
