The automobile body is an important component of the automobile, and can enhance the anti-collision capability of the automobile. At present, most automobiles basically adopt non-bearing type automobile bodies, and separate girders are required to transmit force and install parts such as chassis, power and the like, so that the number of parts is large. The integral type automobile body gradually becomes the trend of research and development design, but the die casting size of integral type automobile body is too big, and current die casting machine tonnage is in 9000 tons basically, can't satisfy the die casting requirement of jumbo size integral type automobile body. Moreover, because the die-casting size of the integrated car body is larger, the mechanical property of the formed car body at a position far away from the casting nozzle is poor, and the car body is easy to crack.

In view of the above, embodiments of the present invention provide a vehicle body and a vehicle, where the vehicle body includes a first vehicle body and a second vehicle body, the first vehicle body and the second vehicle body may be die-cast by using existing equipment, the die-cast dimensions are smaller during die-casting, and the lengths of the positions after die-casting from the pouring gate are moderate, so that the problem that the mechanical properties of the castings are poor due to the distance from the pouring gate is prevented, and the performance of the whole vehicle body is improved. Meanwhile, the longitudinal connecting structure is connected with the first vehicle body and the second vehicle body, and meanwhile, the lap joint area of the first vehicle body and the second vehicle body is also connected, so that the contact area of the longitudinal connecting structure when the first vehicle body and the second vehicle body are connected is increased, the connection reliability is effectively improved, and the mechanical property of the vehicle body is guaranteed.

In order to better understand the above technical solutions, the following describes the above technical solutions in detail with reference to the accompanying drawings.

As shown in fig. 1,2, 8 and 9, the embodiment of the invention proposes a vehicle body, which includes a first vehicle body 100, a second vehicle body 200 and a longitudinal connecting structure 300, wherein the first vehicle body 100 and the second vehicle body 200 are arranged along a length direction of a vehicle and are all integrally formed, ends of the first vehicle body 100 and the second vehicle body 200 along a width direction of the vehicle are inserted, middle parts of the first vehicle body 100 and the second vehicle body 200 along the width direction of the vehicle are overlapped, and the longitudinal connecting structure 300 connects overlapping areas of the first vehicle body 100, the second vehicle body 200 and the first vehicle body 100 and the second vehicle body 200.

In the technical solution adopted in this embodiment, the vehicle body includes a first vehicle body 100, a second vehicle body 200, and a longitudinal connecting structure 300 connecting the first vehicle body 100 and the second vehicle body 200, where the first vehicle body 100 and the second vehicle body 200 are respectively integrally formed structures. That is, the first body 100 and the second body 200 are each formed by integrating a plurality of sheet metal parts into one die casting, which not only facilitates production and reduces the number of assembly steps of the vehicle, but also can achieve weight saving and reduction in parts. Moreover, the first body 100 and the second body 200 can be die-cast using existing equipment, reducing the demand for press tonnage and saving the cost of re-developing the mold. In addition, the first body 100 and the second body 200 are small in die casting size during die casting, and the lengths of the positions after die casting are moderate from the casting nozzle, so that the problem that the mechanical properties of castings are poor due to the fact that the positions are far from the casting nozzle is prevented, and the performance of the whole body is improved. Meanwhile, the longitudinal connecting structure 300 connects the overlap region of the first body 100 and the second body 200 at the same time as connecting the first body 100 and the second body 200, the contact area of the longitudinal connecting structure 300 when the longitudinal connecting structure and the longitudinal connecting structure are connected is increased, the connection reliability is effectively improved, and the mechanical property of the vehicle body is guaranteed. In addition, the overlapping area between the first body 100 and the second body 200 has high strength and is not easily broken. In addition, since the strength of the overlap area of the first body 100 and the second body 200 is relatively high, the longitudinal connection structure 300 and the overlap area can be prevented from being broken when being locked and fixed, the reliability of the first body 100 and the second body 200 is further improved, and the mechanical properties of the whole body are further improved.
