Alternatively, the rear wheel house 20, the rear side member 10 and the rear floor assembly are all connected by welding, but the connection method between the rear wheel house 20, the rear side member 10 and the rear floor assembly is not limited thereto, and in other embodiments, the rear wheel house 20, the rear side member 10 and the rear floor assembly may be connected by riveting.
In the vehicle body structure 100, there are two rear side members 10, two rear wheel houses 20, and two side member covers 30, and the two rear side members 10, the two rear wheel houses 20, and the two side member covers 30 are provided on both sides of the rear floor panel 60, respectively.
In the present embodiment, as shown in fig. 2, 3 and 4, the extension portion 32 and the rear wheel casing 20 are connected in a sealing manner by a sealant. The sealing glue is arranged between the extension part 32 and the rear wheel cover 20, so that the extension part 32 is connected with the rear wheel cover 20 in a sealing mode, the sealing effect is good, the structure is simple, and the realization is convenient. In other embodiments, the extending portion 32 and the rear wheel cover 20 may be connected in a sealing manner by providing a sealing rubber, a sealing strip, or the like between the extending portion 32 and the rear wheel cover 20.
When the longitudinal beam cover plate 30 covers the groove 11 of the rear longitudinal beam 10, sealant is provided between the flanging portion 31 of the longitudinal beam cover plate 30 and the connecting portion 13 of the rear longitudinal beam 10, and when the rear wheel cover 20 is connected to the connecting side 12 of the rear longitudinal beam 10, sealant is also provided between the rear wheel cover 20 and the connecting side 12 of the rear longitudinal beam 10, so that the sealing performance among the longitudinal beam cover plate 30, the rear longitudinal beam 10 and the rear wheel cover 20 can be improved, and the risk of water seepage and water leakage of the vehicle body structure 100 can be further reduced.
In an exemplary embodiment, the sealant is made of synthetic rubber, and a solvent-free reactive adhesive using rubber as a base material has high viscosity at room temperature, is a rubber elastomer after being heated and cured, and has excellent sealing and water leakage preventing functions. In other embodiments, the sealant may also be one of polysulfide sealant, silicone sealant, polyurethane sealant or silane hybrid sealant.
In the present embodiment, as shown in fig. 2 and 5, the extending portion 32 extends out of the shielding region 50 at least at one end in the extending direction of the rear side member 10. By extending the extending portion 32 out of the shielding region 50 at the end portion of the rear side member 10 in the extending direction, the contact surface between the extending portion 32 located in the shielding region 50 and the rear wheel cover 20 is improved, and the sealing effect between the extending portion 32 and the rear wheel cover 20 can be improved.
Further, the extending portions 32 extend out of the shielding regions 50 at both ends in the extending direction of the rear side member 10, respectively. The extending portions 32 extend out of the shielding areas 50 at two ends of the extending direction of the rear longitudinal beam 10, so that the positions of the rear wheel covers 20 in the shielding areas 50 can be in sealing connection with the extending portions 32, and the problem that sealant cannot be further supplemented among the rear longitudinal beam 10, the longitudinal beam cover plate 30 and the rear wheel covers 20 in the shielding areas 50 in subsequent processing can be solved, and the sealing performance of the vehicle body structure 100 is improved. In addition, the two ends of the extending portion 32 extend out of the shielding area 50 and then can be butted with the flanges of the longitudinal beam cover plate 30 located outside the shielding area 50, so that sealant can be supplemented to the rear wheel cover 20 and the extending portion 32 extending out of the shielding area 50 in subsequent processing, the sealing effect is further improved, and the problem that the vehicle body structure 100 leaks water or leaks water when the whole vehicle wades is solved.
That is to say, by arranging the extending portion 32 on the flanging portion 31 and arranging the sealant between the extending portion 32 and the rear wheel cover 20 when the rear wheel cover 20 is connected to the connecting side 12, the sealing of the connecting positions of the flanging portion 31, the connecting portion 13 and the rear wheel cover 20, which are shielded by the shielding region 50, is realized through the sealing connection between the extending portion 32 and the rear wheel cover 20, so as to solve the problem that the sealant cannot be coated at the shielding region 50 in the subsequent process, and further only the sealant needs to be coated at the connecting positions of the flanging portion 31, the connecting portion 13 and the rear wheel cover 20 outside the shielding region 50 in the subsequent process (so as to solve the problem that the sealant is scraped when the longitudinal beam cover plate 30 is covered on the rear longitudinal beam 10, and the sealant needs to be further supplemented after the rear wheel cover 20 is assembled, but the sealant cannot be supplemented at the shielding region 50).
The length of the burring 31 in the extending direction of the rear side member 10 is greater than the length of the extending 32 in the extending direction of the rear side member 10. By setting the length of the extension portion 32 in the extending direction of the rear side member 10 to be smaller than the length of the hem portion 31 in the extending direction of the rear side member 10, it is not necessary to provide the extension portion 32 on the entire hem portion 31, which saves materials and reduces manufacturing costs.
Optionally, the extension 32 and the cuff 31 are integrally formed. In the above technical solution, the extension portion 32 and the flanging portion 31 are integrally formed, that is, the extension portion 32 and the flanging portion 31 are integrally formed in the machining process, so as to enhance the connection strength between the extension portion 32 and the flanging portion 31, and avoid the problem that the extension portion 32 and the flanging portion 31 need to be sealed.
In addition, the embodiment of the present application also provides a vehicle including the vehicle body structure 100 described above. The vehicle adopting the vehicle body structure 100 solves the problem that the flanging of the longitudinal beam cover plate 30, the connecting part 13 of the rear longitudinal beam 10 and the connecting position of the rear wheel cover 20 in the shielding area 50 cannot be further coated with sealant in subsequent processing, so that the sealing effect among the longitudinal beam cover plate 30, the rear longitudinal beam 10 and the rear wheel cover 20 can be improved, the risk that water flows into or permeates into a passenger compartment when the vehicle is involved in water can be reduced, and the quality of the whole vehicle of the vehicle can be improved.
