Abstract
The invention relates to an automobile rear floor bearing structure, comprising a rear floor of an automobile, rear longitudinal beams, rear floor side boards, rear floor reinforcing parts and rear floor nut boards. The two rear floor reinforcing parts are welded onto the front half part of the rear floor, namely near to the upper parts of the left and the right of one side in the automobile; the outer side edges of the two rear floor reinforcing parts as well as the left side and the right side of the rear floor are welded onto the rear floor side boards, and the inter side edges extend to the edge of the tire placing groove of the rear floor and are in welded connection with the rear floor; and the rear floor nut boards are in the shape of a stripe and are clamped between the rear floor and the rear floor reinforcing parts and welded onto the rear floor and the rear floor reinforcing parts. The automobile floor rear part bearing structure has reasonable design and good strength, is easy to assemble and weld and can be suitable for the automobile whose trunk needs to be provided with a gas tank.
Description
Technical field
The present invention relates to vehicle body structure, specifically relate to a kind of need are settled the vehicle of gas tank in luggage compartment floor panel structure design.
Background technology
Automotive floor panel structure mainly is load-bearing, collision safety and the usefulness that each systematic part installation is provided.The CNG automobile of the many vehicles of existing market is continued to use is the rear floor structure of common fuel-engined vehicle, and rear portion, plate ground has a lot of deficiencies in design, mainly is the structure more complicated, does not manifest good reinforcement, crashproof, attractive in appearance and supporting role.For the CNG automobile, need settle gas tank in luggage compartment usually, just ftracture easily owing to stressed bad in back floor.
Summary of the invention
The technical problem to be solved in the present invention is the shortcoming that overcomes prior art, a kind of reasonable in design is provided, simple is suitable for, welding is simple with assembling, intensity better reaches the rear floor bearing structure of at utmost optimizing the space and being applicable to the automobile of CNG vehicle.
Technical scheme of the present invention is as follows:
A kind of rear floor bearing structure of automobile, it comprises automobile rear floor, floor side member and rear floor margin plate, the right and left on back floor is by flange and rear floor margin plate welding; Floor side member is welded on the bottom surface of floor, back the right and left.
It also includes back floor reinforcement and floor, back nutplate, floor, described back reinforcement is two, be welded on floor, back forebody, promptly lean on the top of the right and left of a side in the car, the outer side edges of floor, two backs reinforcement is welded with rear floor margin plate with the right and left on floor, back respectively, the inner side edge of floor, two backs reinforcement extends to the edge of the tire standing groove on floor, back always, is welded to connect with the floor, back; Floor, described back nutplate is a strip shape, is sandwiched between floor, back and floor, the back reinforcement, and fixing with their welding.
Described floor side member cross section is L shaped, and weld with the base on floor, back on one side of floor side member, and formation one cavity shape structure is surrounded in the following portion welding of another side and rear floor margin plate in the middle of back floor, floor side member and the rear floor margin plate.
For the CNG vehicle, because floor, back forebody (promptly by one side in the car) is the zone of assembling gas tank, this structure becomes together with floor, back nutplate assembly welding by the back floor reinforcement on floor, back and both sides, and this zone is strengthened, and reaches the effective support to gas tank.In addition, floor side member is designed to L shaped, combines with back floor and rear floor margin plate actv. and to form the osed top cavity shape structure, increasing load-carrying capacity like this, when improving the intensity of car body, also help the weld-on installation of these three parts.
Therefore structure of the present invention compared with prior art has advantages such as load-carrying properties are good, intensity original text, good manufacturability, safety.
Description of drawings
Fig. 1 is a birds-eye view of the present invention;
Fig. 2 is Figure 1A-A cutaway view
Among the figure: floor, 1,1 back, floor, back reinforcement (left and right each), 3 floor side members (left and right each), floor, 4 back nutplate (left and right each), 5 rear floor margin plates (left and right each)
The specific embodiment
Further specify the present invention below in conjunction with accompanying drawing:
Referring to Fig. 1 and Fig. 2, this rear floor carrying structure comprises automobile rear floor 1, floor side member 3 and rear floor margin plate 5, back floor reinforcement 2 and floor, back nutplate 4.The right and left on back floor 1 is by flange and rear floor margin plate 5 welding, and floor side member 3 is welded on the bottom surface of floor, back 1 the right and left.The cross section of floor side member 3 is L shaped, weld with the base on floor 1, back on its one side, the following portion of another side and rear floor margin plate 5 welds, and just surrounds in the centre of floor 1, back, floor side member 3 and rear floor margin plate 5 like this to have formed a cavity shape structure, has better load-carrying capacity.
Back floor reinforcement about 2 respectively is provided with one, be welded on the forebody on floor 1, back, promptly lean on the top of the right and left of a side in the car, the outer side edges of floor, two backs reinforcement 2 is welded with the right and left and the rear floor margin plate 5 on floor, back respectively, the inner side edge of floor, two backs reinforcement 2 extends to the edge of the tire standing groove on floor 1, back always, is welded to connect with floor 1, back.Back floor nutplate 4 is in order to provide to the gas tank mounting bracket support to be installed, and it is a strip shape, be sandwiched between floor 1, back and floor, the back reinforcement 2, and fixing with their welding.
The technology welding manner of this structure is: the 1st step was welded into the little assembly in floor, back earlier with floor 1, back, floor reinforcement 2 and floor, back nutplate 4, the 2nd step incited somebody to action back little assembly in floor and floor side member 3 and rear floor margin plate 5 again and welds, form the osed top cavity shape structure, welding manner is spot welding.
