Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the embodiments of the utility model.

[0025] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0026] In addition, in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the embodiments of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0028] In addition, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the embodiments of the present utility model.

[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 plug-in and overlap, which is not only simple in structure but also convenient in operation. Moreover, the overlap area and the plug-in area of ​​the first vehicle body and the second vehicle body have increased strength due to the superimposed thickness in the vertical direction, and are not easy to break, which can further improve the mechanical properties and structural strength of the entire 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 1As shown, an embodiment of the utility model proposes a vehicle body, which includes a first vehicle body 100 and a second vehicle body 200 arranged along the length direction of the vehicle, the first vehicle body 100 and the second vehicle body 200 are respectively an integrally formed structure, the first vehicle body 100 and the second vehicle body 200 are plugged in at the ends along the width direction of the vehicle, and the first vehicle body 100 and the second vehicle body 200 are overlapped in the middle along the width direction of the vehicle.

[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 fewer parts. 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 vehicle body 100 and the second vehicle body 200 are connected by plug-in and overlap, with a simple structure and convenient operation. Furthermore, the overlapping areas and the plug-in areas of the first vehicle body 100 and the second vehicle body 200 have increased strength due to the superimposed thickness in the vertical direction and are not easily broken, which can further improve the mechanical properties and structural strength of the entire vehicle 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] The first body 100 and the second body 200 can be fixed together in the length direction by welding or mechanical connection. To improve the reliability of the first body 100 and the second body 200 after being connected, 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 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] Exemplarily, in one embodiment of the utility model, the vehicle body further includes a locking member 300, and the locking member 300 connects the overlapping area of ​​the first vehicle body 100 and the second vehicle body 200. In order to further improve the reliability of the connection between the first vehicle body 100 and the second vehicle body 200, a locking member 300 is provided, and the first vehicle body 100 and the second vehicle body 200 are tightly and reliably connected together by the locking member 300. In one embodiment, the locking member 300 connects the overlapping area in the vertical direction. Since the overlapping area has a large thickness and a large strength, the locking member 300 can prevent the vehicle body from cracking when it is locked and fixed with the vehicle body. As an optional method, the locking member 300 can be a bolt, SPR (rivet), FDS (flow drill screw), etc., which is easy to connect and has high reliability.

[0037] For example, in one embodiment of the present invention, a plurality of locking members 300 are provided at intervals along the width direction of the vehicle. In this way, locking force can be provided at multiple positions, further improving the firmness of the connection between the first body 100 and the second body 200. In one embodiment, a plurality of locking members 300 are staggered in the width direction, so that locking force can also be provided in the length direction of the vehicle, thereby improving the firmness of the connection between the first body 100 and the second body 200.

[0038] For example, in one embodiment of the present invention, the first vehicle body 100 includes an integrally die-cast first floor 110 and a first longitudinal beam 120, the second vehicle body 200 includes an integrally die-cast second floor 210 and a second longitudinal beam 220, the first floor 110 and the second floor 210 overlap, the first longitudinal beam 120 and the second longitudinal beam 220 plug in, and the locking member 300 connects the overlapping area of ​​the first floor 110 and the second floor 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 110 and the second floor 210 overlap, the first longitudinal beam 120 and the second longitudinal beam 220 plug in, and the locking member 300 locks and fixes the first floor 110 and the second floor 210 together in the vertical direction to prevent the first floor 110 and the second floor 210 from separating in the length direction. In this embodiment, two first longitudinal beams 120 are provided, and the two longitudinal beams 120 are respectively arranged on both sides of the first floor 110 along the vehicle width direction, that is, the two first longitudinal beams 120 form the ends of the first body 100 along the vehicle width direction, and the first floor 110 forms the middle part of the first body 100 along the vehicle 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 210 along the vehicle width direction, that is, the two second longitudinal beams 220 form the ends of the second body 200 along the vehicle width direction, and the second floor 210 forms the middle part of the second body 200 along the vehicle width direction.

[0039] Exemplarily, in an embodiment of the present invention, the vehicle body further includes a longitudinal connector 400, which connects the first longitudinal beam 120 and the second longitudinal beam 220. In order to improve the reliability of the connection between the first longitudinal beam 120 and the second longitudinal beam 220, the longitudinal connector 400 is provided, and the longitudinal connector 400 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 and affecting the overall strength of the vehicle body.

[0040] 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 connector 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 connector 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 connector 400 can also be connected to the first body 100 and the second body 200 respectively, which is not limited here.

[0041] The longitudinal connector 400 includes a connecting body 410, a first connecting plate 420 and a second connecting plate 430. The connecting body 410, the first connecting plate 420 and the second connecting plate 430 are integrally formed, which can reduce the use of parts and improve the overall structural strength. The connecting body 410 is arranged in the plug-in cavity and connects the first floor 110 and the second floor 210. The first connecting plate 420 and the second connecting plate 430 are arranged at both ends of the connecting body 410 along the length direction of the vehicle. The first connecting plate 420 is connected to the first longitudinal beam 120, and the second connecting plate 430 is connected to the second longitudinal beam 220, thereby connecting the first longitudinal beam 120 and the second longitudinal beam 220 into a whole.

[0042] As an optional method, the connecting body 410 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.

[0043] For example, in one embodiment of the present invention, the first longitudinal beam 120 and the second longitudinal beam 220 are clearance-matched, so that the friction force when the first longitudinal beam 120 and the second longitudinal beam 220 are plugged in can be reduced, thereby improving the convenience of plugging in.

[0044] For example, in one embodiment of the present invention, at least one of the connection between the longitudinal connector 400 and the first longitudinal beam 120 and the connection between the longitudinal connector 400 and the second longitudinal beam 220 is a mechanical connection. The connection is made by a mechanical connection such as bolts, SPR (rivets), or FDS (flow drill screws), which is simple and has high reliability.

[0045] 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.

[0046] 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.

[0047] 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.
