Abstract
The utility model discloses a lap-connection structure of a front floor assembly and a back floor assembly. The lap-connection structure comprises the front floor assembly and the back floor assembly. The front floor assembly is fixedly connected with the back floor assembly. The front floor assembly is composed of a front floor and a front floor edge longitudinal beam. The back floor assembly is composed of a back longitudinal beam connecting plate and a back floor. The front floor is fixedly connected with the back floor. The lap-connection structure is characterized in that the front floor edge longitudinal beam is connected with the back longitudinal beam connecting plate in a lapping mode. The original welding connection of the joint of the front floor edge longitudinal beam and the back longitudinal beam connecting plate is replaced so that the front floor and the back floor can be both placed on the two sides of the front portion of the back longitudinal beam connecting plate and on the two sides of the front portion of the front floor edge longitudinal beam. A cross clamping shape of the back longitudinal beam connecting plate and the front floor edge longitudinal beam is formed by the front floor and the back floor, and therefore part rigidity and intensity are improved. Sliding force between the plate faces is increased when the sides of the plates are collided. Breakage risk of the lap-connecting position is reduced.
Description
Technical field
The utility model relates to automobile technical field, refers to particularly it is a kind of front floor assembly and rear floor assembly bridging arrangement.
Background technology
Along with the development of motorcar body technology, more and more higher to rigidity and the side impact security requirement of body in white, floor panel structure for automobile body is the important component part of vehicle body.For the integral rigidity and the side impact performance that guarantee body in white, the lap-joint of front floor assembly and rear floor assembly just need to have enough Rigidity and strengths.Might reduce when improving lap-joint's Rigidity and strength and close the weldering assembly process process, involutory being welded joined the accuracy requirement raising, causes productive costs to increase.Therefore design a kind of take into account rigidity, side impact safety and close the connection structure of forward and backward floor assembly of weldering assembly process process necessary.
The utility model content
The purpose of this utility model is exactly the deficiency that will solve the above-mentioned background technology, a kind of risk that both can reduce forward and backward floor assembly lap-joint fracture in the side impact is provided, has simultaneously the good front floor assembly and the rear floor assembly bridging arrangement that close the weldering assembly technology.
The technical solution of the utility model is: a kind of front floor assembly and rear floor assembly bridging arrangement, it comprises front floor assembly and the rear floor assembly of captive joint, described front floor assembly is made of front floor and front ground edges of boards longeron, described rear floor assembly is made of back rail junction plate and rear floor, captive joint with rear floor in front floor, its special character is: described front ground edges of boards longeron is connected connection with back rail junction plate.
In such scheme: the end of described front ground edges of boards longeron is provided with the first lap plate, the end of back rail junction plate is provided with the second lap plate that is complementary with the first lap plate, by cooperatively interacting of the first lap plate and the second lap plate, ground edges of boards longeron is connected connection before realizing with back rail junction plate.
The cross section of described the first lap plate and the second lap plate is the L shaped of a pair of mutual coupling.
When assembling, first front ground edges of boards longeron and back rail junction plate are overlapped, behind the overlap joint, weld front floor and front ground edges of boards longeron, make the front floor assembly of its formation, welding back rail junction plate and rear floor consist of, and make it consist of rear floor pan assembly, again front floor and rear floor welded, make front floor and rear floor consist of floor assembly at last.
Adopt the utility model, can make front floor, rear floor both be arranged in the both sides, the place ahead of back rail junction plate, be arranged in again the both sides, the place ahead of front ground edges of boards longeron, make front floor, rear floor form intersection clamping shape to back rail junction plate and front ground edges of boards longeron, thereby improve district section Rigidity and strength, when side impact, increase the skid force between the plate face, reduce the risk of lap-joint's fracture.
Description of drawings
Fig. 1 is the utility model integral structure schematic diagram;
Fig. 2 is the utility model integral structure exploded perspective view.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to be well understood to the utility model, but they do not consist of restriction to the utility model.
Such as Fig. 1, a kind of front floor assembly shown in Figure 2 and rear floor assembly bridging arrangement, it comprises front floor assembly and the rear floor assembly of captive joint, front floor assembly is made of with front ground edges of boards longeron 2 front floor 1, rear floor assembly is made of back rail junction plate 3 and rear floor 4, front floor 1 be connected floor 4 and be welded and fixed connection, front ground edges of boards longeron 2 is connected overlap joint and is connected with back rail junction plate, be specially: the end of front ground edges of boards longeron 2 is provided with the first lap plate 2.1, the end of back rail junction plate 3 is provided with the second lap plate 3.1, the first lap plates 2.1 of being complementary with the first lap plate 2.1 and the cross section of the second lap plate 3.1 is the L shaped of a pair of mutual coupling.Overlap joint connection replacement original front ground edges of boards longeron 2 and back rail junction plate 3 interfaces of being connected with back rail junction plate by front ground edges of boards longeron 2 are welded to connect, so just can make front floor 1, rear floor 4 both be arranged in the both sides, the place ahead of back rail junction plate 3, be arranged in again the both sides, the place ahead of front ground edges of boards longeron 2, make front floor 1, the 4 pairs of back rail junction plates 3 in rear floor and front ground edges of boards longeron 2 form intersection clamping shape, thereby improve district section Rigidity and strength, when side impact, increase the skid force between the plate face, reduce the risk of lap-joint's fracture.
The utility model is simple in structure, and is reasonable in design, is a kind ofly to take into account rigidity, side impact safety and close the weldering front floor assembly of assembly process process and the connection structure of rear floor assembly.
