[0029] As an important part of the car, the car body can enhance the car's anti-collision ability. At present, most cars basically use non-load-bearing bodies, which require a separate beam to transmit force and install chassis, power and other components, and a large number of parts are used. One-piece bodies have gradually become a trend in research and development design, but the die-casting size of the one-piece body is too large, and the tonnage of existing die-casting machines is basically within 9,000 tons, which cannot meet the die-casting requirements of large-size one-piece bodies. Moreover, due to the large die-casting size of the one-piece body, the mechanical properties and structural strength of the formed body are not good at a position far away from the casting mouth, and it is easy to crack.

[0030] In view of this, the embodiment of the utility model provides a vehicle body and a vehicle, wherein the first vehicle body and the second vehicle body can be die-casted using existing equipment, the die-casting size is small during die-casting, and the distance between each position and the casting port after die-casting is moderate, thereby preventing the problem of poor mechanical properties of the casting due to the long distance from the casting port, and improving the mechanical properties and structural strength of the entire vehicle body. At the same time, the first vehicle body and the second vehicle body are connected by plugging and overlapping, and a vertical connection structure is provided in the vertical gap formed by the first vehicle body and the second vehicle body, which can tightly fix the first vehicle body and the second vehicle body together, improve the reliability of the overlap, and further increase the thickness of the overlap area, thereby improving the strength of the vehicle body.

[0031] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 3 As shown, an embodiment of the utility model proposes a vehicle body, which includes a first vehicle body 100, a second vehicle body 200 and a vertical connection structure 300. The first vehicle body 100 and the second vehicle body 200 are arranged along the length direction of the vehicle, and the first vehicle body 100 and the second vehicle body 200 are plugged in at their ends along the width direction of the vehicle. The first vehicle body 100 and the second vehicle body 200 are spaced apart in the vertical direction in the middle along the width direction of the vehicle to form a vertical gap 500. The vertical connection structure 300 is arranged in the vertical gap 500 and connects the first vehicle body 100 and the second vehicle body 200.

[0033] In the technical solution adopted in this embodiment, the vehicle body includes a first vehicle body 100 and a second vehicle body 200 connected along the length direction, and the first vehicle body 100 and the second vehicle body 200 are respectively integrally formed structures. That is to say, the first vehicle body 100 and the second vehicle body 200 respectively integrate multiple sheet metal parts into a die-casting part, which not only facilitates production and reduces the assembly steps of the vehicle, but also can achieve lightweight and simplification. Moreover, the first vehicle body 100 and the second vehicle body 200 can be die-casted using existing equipment, which reduces the requirements for the tonnage of the press and saves the cost of redeveloping the mold. In addition, the first vehicle body 100 and the second vehicle body 200 have a small die-casting size during die-casting, and the length of each position from the casting port after die-casting is moderate, thereby preventing the casting from having poor mechanical properties due to being far away from the casting port, and improving the mechanical properties and structural strength of the entire vehicle body. At the same time, the first body 100 and the second body 200 are connected by plugging and overlapping, which is easy to operate. The overlapping area and the plugging area have superimposed thickness in the vertical direction, so the strength is increased and it is not easy to break, which further improves the mechanical properties and structural strength of the entire body. In addition, the vertical connection structure 300 set in the vertical gap 500 can tightly fix the first body 100 and the second body 200 together, improve the reliability of the overlap, and can further increase the thickness of the overlap area, thereby improving the strength of the body.

[0034] Specifically, the vehicle body includes a first vehicle body 100 and a second vehicle body 200. The first vehicle body 100 and the second vehicle body 200 are both integrally formed structures, which can reduce the use of parts and components and improve structural strength. It is understandable that the first vehicle body 100 and the second vehicle body 200 are relatively small in size and can be produced using existing die-casting machines and other equipment, preventing the die-casting size from being too large and reducing the mechanical properties of the casting away from the casting port.

[0035] In order to improve the reliability of the connection between the first body 100 and the second body 200, the first body 100 and the second body 200 are plugged and overlapped in the width direction, which has a simple structure and is easy to operate. In other words, the end of the first body 100 along the vehicle width direction and the end of the second body 200 along the vehicle width direction are plugged, the middle of the first body 100 along the vehicle width direction and the middle of the second body 200 along the vehicle width direction are overlapped, and the vertical gap is set in the overlap area of ​​the first body 100 and the second body 200. In addition, since the thickness of the overlap area and the plug-in area of ​​the first body 100 and the second body 200 is large, it is not easy to crack, thereby improving the mechanical properties and structural strength of the entire body.

[0036] In addition, in this embodiment, the vehicle body is also provided with a vertical connection structure 300, and the vertical connection structure 300 is arranged in the vertical gap 500 formed by the first vehicle body 100 and the second vehicle body 200 in the vertical direction. It can be understood that the first vehicle body 100, the vertical connection structure 300 and the second vehicle body 200 are arranged in a superimposed manner in the vertical direction, which can further increase the thickness of the overlap area. In addition, the vertical connection structure 300 connects the first vehicle body 100 and the second vehicle body 200 in the vertical direction, and can tightly connect the first vehicle body 100 and the second vehicle body 200 together, thereby improving the reliability of fixing the first vehicle body 100 and the second vehicle body 200. In this embodiment, the vertical direction is the height direction of the vehicle. That is, the middle part of the first vehicle body 100 along the vehicle width direction and the middle part of the second vehicle body 200 along the vehicle width direction are arranged in the vehicle height direction at intervals, thereby forming a vertical gap, that is, a gap in the vehicle height direction.

[0037] For example, refer to Figure 4 In one embodiment of the utility model, the vertical connection structure 300 includes a support plate 310, and the support plates 310 are provided with a plurality of them. The plurality of support plates 310 are connected end to end to form a support cavity, one of the plurality of support plates 310 is connected to the first vehicle body 100, and another of the plurality of support plates 310 is connected to the second vehicle body 200.

[0038] Specifically, the vertical connection structure 300 includes a support plate 310, and the support plate 310 is provided with multiple pieces and connected end to end to form a support cavity, which has higher strength than a solid plate structure. As an optional method, two support plates 310 are relatively arranged in the vertical direction, wherein one support plate 310 is arranged parallel to the first body 100 and connected to the first body 100, and the other support plate 310 is arranged parallel to the second body 200 and connected to the second body 200, so that the first body 100 and the second body 200 can be conveniently fixed together. In one embodiment, the support plate 310 is connected to the first body 100 or the support plate 310 is connected to the second body 200 by welding; it can also be connected by bolts, SPR (rivets), FDS (flow drill screws), etc., which is convenient to connect and has high reliability.

[0039] Exemplarily, in one embodiment of the present invention, the vertical connection structure 300 further includes a reinforcing plate, which is disposed in the support cavity, and the reinforcing plate connects two opposite support plates 310. In order to improve the structural strength of the support cavity, the reinforcing plate is provided, and the oppositely arranged support plates 310 can be supported by the reinforcing plate, thereby improving the structural strength of the entire support cavity.

[0040] For example, in one embodiment of the present invention, multiple reinforcing plates are provided, and the multiple reinforcing plates are staggered, so that support can be provided in both longitudinal and vertical directions, further improving the stability and reliability of the support cavity when subjected to forces in different directions.

[0041] For example, refer to Figure 3 In one embodiment of the utility model, the first vehicle body 100 includes a first floor panel 110 and a first longitudinal beam 120 formed by integral die casting, and the second vehicle body 200 includes a second floor panel 210 and a second longitudinal beam 220 formed by integral die casting. The first floor panel 110 and the second floor panel 210 are arranged at intervals in the vertical direction to form a vertical gap 500, one of the plurality of support plates 310 is connected to the first floor panel 110, and another of the plurality of support plates 310 is connected to the second floor panel 210. It can be understood that the integral die casting can save the number of parts and improve the structural strength. Among them, the first floor panel 110 and the second floor panel 210 are arranged at intervals in the vertical direction, and the vertical connection structure 300 locks the first floor panel 110 and the second floor panel 210 together to prevent the first floor panel 110 and the second floor panel 210 from being separated and misaligned in the length direction, thereby ensuring the reliability of the connection.

[0042] In one embodiment, two first longitudinal beams 120 are provided, and the two longitudinal beams 120 are respectively arranged on both sides of the first floor panel 110 in the width direction, that is, the two first longitudinal beams 120 form the ends of the first vehicle body 100 in the width direction, and the first floor panel 110 forms the middle part of the first vehicle body 100 in the width direction. Two second longitudinal beams 220 are provided, and the two second longitudinal beams 220 are respectively arranged on both sides of the second floor panel 210 in the width direction, that is, the two second longitudinal beams 220 form the ends of the second vehicle body 200 in the width direction, and the second floor panel 210 forms the middle part of the second vehicle body 200 in the width direction.

[0043] For example, refer to Figure 2 and Figure 3 In one embodiment of the utility model, the vehicle body further includes a longitudinal connection structure 400 , the longitudinal connection structure 400 connects the first longitudinal beam 120 and the second longitudinal beam 220 , and the longitudinal connection structure 400 is connected to the vertical connection structure 300 .

[0044] In order to improve the reliability of the connection between the first longitudinal beam 120 and the second longitudinal beam 220, a longitudinal connection structure 400 is provided, which tightly fixes the first longitudinal beam 120 and the second longitudinal beam 220 together in the length direction to prevent the first longitudinal beam 120 and the second longitudinal beam 220 from being separated or misaligned and affecting the overall strength of the vehicle body.

[0045] Exemplarily, in one embodiment of the utility model, the first longitudinal beam 120 and the second longitudinal beam 220 both have a plug-in cavity, and the longitudinal connection structure 400 is arranged inside the plug-in cavity. In other words, the ends of the first longitudinal beam 120 and the second longitudinal beam 220 facing each other are both hollow structures with openings, and the first longitudinal beam 120 can be inserted into the interior of the second longitudinal beam 220, or the second longitudinal beam 220 can be inserted into the interior of the first longitudinal beam 120. The longitudinal connection structure 400 is arranged in the plug-in cavity, and can penetrate the plug-in area (i.e., the superimposed position) of the first longitudinal beam 120 and the second longitudinal beam 220 in the vertical direction, thereby fixing the first longitudinal beam 120 and the second longitudinal beam 220 together. Of course, in other embodiments, the longitudinal connection structure 400 can also be connected to the first body 100 and the second body 200 respectively, which is not limited here.

[0046] Reference Figure 5 The longitudinal connection structure 400 includes a connection body, a first connection plate 420 and a second connection plate 430. The connection body, the first connection plate 420 and the second connection plate 430 are integrally formed, which can reduce the use of parts and improve the overall structural strength. The connection body is arranged in the plug-in cavity and connects the first floor 110 and the second floor 210. The first connection plate 420 and the second connection plate 430 are arranged at both ends of the connection body along the length direction of the vehicle. The first connection plate 420 is connected to the first longitudinal beam 120, and the second connection plate 430 is connected to the second longitudinal beam 220, so that the first longitudinal beam 120 and the second longitudinal beam 220 are connected into a whole.

[0047] As an alternative, refer to Figure 5 The connecting body includes a first side plate 411, a second side plate 412, a third side plate 413, a fourth side plate 414 and a vertical plate 415. It can be understood that the first side plate 411, the second side plate 412, the third side plate 413 and the fourth side plate 414 form a cavity, which can take into account both structural strength and material saving. By setting the vertical plate 415, on the one hand, the structural strength can be further improved, and on the other hand, it can also facilitate the connection of the overlap area and improve the assembly efficiency.

[0048] For example, refer to Figure 3 In one embodiment of the utility model, the vertical connection structure 300 further includes a blocking plate 320, which is disposed in the support cavity, and the vertical plate 415 is connected to the blocking plate 320. Specifically, the blocking plate 320 can not only provide support for the support cavity, but also be conveniently connected to the vertical plate 415, thereby improving the convenience of connecting the vertical connection structure 300 and the longitudinal connection structure 400.

[0049] For example, in one embodiment of the present invention, the blocking plate 320 and the plurality of supporting plates 310 are integrally formed, thereby reducing the use of components and improving the overall structural strength.

[0050] Exemplarily, in one embodiment of the utility model, the first body 100 and the rear body of the four-wheel drive vehicle are die-casted by the same mold, and after die-casting, the first body 100 is partially cut off in the length direction to form the second body 200. It is understandable that the first body 100 and the rear body of the four-wheel drive vehicle are die-casted by a common mold. After die-casting by the common mold, the first body 100 can be directly used as the rear body of the 4*4 vehicle (i.e., the four-wheel drive vehicle), without the need to open a new die-casting mold and a tool such as a check fixture, saving development costs. Moreover, when applied to the six-wheel drive vehicle (i.e., the 6*6 vehicle) of this embodiment, it is only necessary to partially cut the first body 100 in the length direction as needed (usually 1050 mm can be cut), and the second body 200 is formed. After the first body 100 and the second body 200 are connected, the rear body of the 6*6 vehicle is formed. It is understandable that the second body 200 can be formed by cutting the corresponding length on the first body 100 according to different vehicle models. In this way, the rear body of different models can be die-cast using the same mold, reducing the number of new molds required to adapt to different models and reducing mold development costs.

[0051] To achieve the above purpose, the embodiment of the utility model provides a vehicle, including the vehicle body described above. Specifically, the specific structure of the vehicle body refers to the above embodiment. Since the vehicle adopts all the technical solutions of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be repeated here.

[0052] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the embodiment of the present invention. All equivalent structural changes made by using the description and drawings of the embodiment of the present invention under the inventive concept of the embodiment of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the embodiment of the present invention.
