The utility model proposes a segmented automobile rear floor structure. The rear floor is composed of three segmented parts welded on the front panel, the middle panel and the rear panel; At the position A of the welding edge in the X positive direction of the front beam of the floor and the integral rear floor, the block line of the middle plate and the rear plate is at the welding edge position B of the X positive direction of the rear floor skeleton beam and the integral rear floor, The front plate, middle plate and rear floor front beam are connected by a three-layer welding structure, and the middle plate, rear plate and rear floor frame beam are also connected by a three-layer welding structure. The rear floor improves the manufacturability of the structure, reduces the manufacturing difficulty of parts tooling and products, and optimizes the welding flanging, which improves the convenience of operation, the feasibility of welding and the reliability of sealing. At the same time, a fuel pump maintenance and installation hole is added on the rear floor to facilitate the maintenance and installation of the fuel pump.
Description
Technical field
The utility model relates to a kind of body structure, specifically, relates to a kind of rear floor structure of automobile.
Background technology
At present, automobile rear floor is a whole punching parts, see Fig. 1, this structural machinability is relatively poor, the part resilience is bigger, because this part is thin, big, heavy, produces, transports a lot by manual carrying simultaneously, adding again that this part generally is responsible for manufacturing by peripheral supplier is transported to main engine plants again, and then part is out of shape easily.And back floor and left and right side weld all around connect flange that assembly welds mutually towards a direction, and back segment usually occurring can't spot welding, can only adopt carbon-dioxide arc welding, because part is too thin, the phenomenons such as poor sealing of burning easily with gluing take place.Simultaneously, do not design special fuel charger maintenance and assembly opening on the back floor, cause the fuel charger maintenance difficult.
The utility model content
Technical problem to be solved in the utility model provides a kind of sectional type rear floor structure of automobile, solves floor, back problem such as easy deformation, welding inconvenience in handling process.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is that original back floor as a whole is divided into three parts, and back floor has three piecemeal part welding to constitute by header board, middle plate and back plate; Be as the criterion with the vehicle body coordinate, the welding edge position A of the X positive dirction on the piecemeal line of described header board and middle plate floor after floor front cross rail and integral type, the welding edge position B of the X positive dirction on piecemeal line floor after rear floor frame crossbeam and integral type of plate and back plate in described, header board, middle plate are connected with three layers of welding structure with floor, back front cross rail, and middle plate, back plate also are connected with three layers of welding structure with the rear floor frame crossbeam.
The flange that described back plate and left and right side weld all around connect the assembly overlap joint is divided into two sections rightabout flange, and the leading portion flange is consistent with the flange direction of header board and middle plate, and the back segment flange is opposite with leading portion flange direction.Fuel charger maintenance and installation hole is set on middle plate.
This structure with integral type after the welding edge position of X positive dirction of the floor front cross rail on floor and rear floor frame crossbeam be the piecemeal line, the floor, back rationally is divided into header board, middle plate and three parts of back plate, has reduced mould the requirement capability of manufacturing line, the difficulty of processing and the component production technical risk of large mold; Reasonably the piecemeal position helps reducing welding times and reduces welding cost.Simultaneously; the rear end of back floor and gusset welding assembly (left and right) overlap joint; adopt two-way flange mode; guaranteed the shop characteristic of welding; adopt when protecting weldering at the position of having avoided in the past can't welding; can not be coated with welded seal glue, cause the generation of phenomenons such as leaking out, leak gas, leak, improve the leak tightness of car load.Simultaneously, fuel charger maintenance and mounting hole, maintenance when making things convenient for fault and installation in the floor, back, have been increased on the plate.

Fig. 3 is a plate welding edge partial enlarged drawing behind the floor, back.
The specific embodiment
As shown in Figure 2, a kind of rear floor structure of the present utility model is made up of header board 4, middle plate 5,6 three parts of back plate, referring to Fig. 1, welding edge position A and B with floor after the former integral type 2 and the X positive dirction (being as the criterion with the vehicle body coordinate) of back floor front cross rail 1 and rear floor frame crossbeam 3 are the piecemeal line, and the floor, back rationally is divided into header board 4, middle plate 5 and 6 three parts of back plate.Header board 4, middle plate 5 and floor, back front cross rail 1, plate 5, back plate 6 are connected with three layers of welding structure respectively with rear floor frame crossbeam 3 in reaching.
In conjunction with Fig. 3, the flange that back plate 6 and left and right side weld all around connect the assembly overlap joint is determined the demarcation line of leading portion flange 7 and back segment flange 8 according to industrial analysis, the flange direction of leading portion flange 7 and header board 4 and middle plate 5 is consistent upwards turns over, 8 directions with leading portion flange 7 of back segment flange are opposite, turn over downwards, guarantee the comfort feature of assembly part welding operation.
Simultaneously, according to the position of fuel charger, offer a maintenance mounting hole 9 on middle plate 5, installation site and openings of sizes will suitably be adjusted according to the fuel tank arrangement requirement.This mounting hole will help the installation and the maintenance of fuel charger.
