Technical Field

[0001] The utility model relates to the field of vehicles, in particular to a vehicle body structure and a vehicle. Background Art

[0002] The current body structure is usually an integrated structure, and manufacturers use a fixed production line for the same model. However, if part of the body structure is upgraded or changed, the entire body structure needs to be changed, and the corresponding entire production line must also be adjusted accordingly, which is very costly and not conducive to the development of vehicles. Utility Model Content

[0003] Therefore, an object of the present invention is to provide a vehicle body structure and a vehicle to at least solve one of the problems existing in the above-mentioned prior art or related art.

[0004] A first aspect of the utility model provides a vehicle body structure, which includes at least two vehicle body modules that are independently assembled and a guide connection structure, wherein the guide connection structure includes a first guide portion and a second guide portion, wherein the first guide portion is arranged on a first vehicle body module of the two mutually connected vehicle body modules, and the second guide portion is arranged on a second vehicle body module of the two mutually connected vehicle body modules, and the first guide portion and the second guide portion can cooperate with each other to guide the first vehicle body module and the second vehicle body module to align with each other at a set position for connection with each other.

[0005] The body structure provided in this embodiment includes at least two body modules that are assembled independently, and then the at least two body modules are assembled together to form a complete body structure. Compared with the one-piece body structure in the related art, when the body structure needs to be partially upgraded or changed, it is only necessary to upgrade or change the corresponding body module, adjust the production line of the corresponding body module, and keep the rest unchanged, which can greatly reduce the cost of transformation and is conducive to the development of the body structure. In addition, in order to facilitate the assembly of at least two body modules together, a guide connection structure is also designed. Specifically, a first guide portion is set on the first body module of the two body modules connected to each other, and a second connection portion is set on the second body module, so that the first guide portion and the second guide portion can cooperate with each other to guide the two body modules to quickly align their positions to connect together, thereby improving assembly efficiency.

[0006] In addition, the vehicle body structure provided in the above embodiments of the present application may also have the following additional technical features:

[0007] In some embodiments, one of the first guide portion and the second guide portion is a groove, and the other is a protrusion. The structure is simple and easy to process. In addition, during the assembly process, the protrusion can easily extend into the groove to guide the two body modules.

[0008] In some embodiments, the guide connection structure further includes a connecting member, which is used to connect the first guide portion and the second guide portion together at a set position. In the assembly process, after the first guide portion and the second guide portion guide the first body module and the second body module to the set position, the first guide portion and the second guide portion are connected together by the connecting member, thereby realizing the connection of the two body modules, and the assembly is convenient and quick. Moreover, connecting the connecting member to the two guide portions can prevent the two guide portions from relative movement or reverse movement.

[0009] In some embodiments, the groove and the protrusion face each other in the direction in which the first body module and the second body module are connected to each other. During assembly, the first body module and the second body module can be brought close to each other by directly referring to the positions of the protrusion and the groove, and then the first body module and the second body module are connected together at the set position during the process of the protrusion and the groove cooperating with each other, so that the first body module and the second body module can be quickly connected.

[0010] In some embodiments, the groove is formed as a track groove extending in the direction in which the first body module and the second body module are connected to each other, and the protrusion can be inserted into the track groove in the direction in which the first body module and the second body module are connected to each other. During assembly, the protrusion and the groove can be matched with each other first, and then the first body module and the second body module can be moved closer to each other under the guidance of the protrusion and the groove until they are at a set position, thereby improving assembly accuracy.

[0011] In some embodiments, the first body module is a front frame module, and the second body module is a cab module. A first guide portion is provided on the front frame module, and a second guide portion is provided on the cab module, so that the two can be connected together quickly and accurately.

[0012] In some embodiments, the first guide portion is a groove formed on the rear side of the front frame module, and the second guide portion is a protrusion formed on the front side of the cab module, and the groove and the protrusion face each other and are plugged into each other. The structure is simple and easy to assemble.

[0013] In some embodiments, the two ends of the rear side of the front frame module have connecting parts extending outward, the grooves are arranged on the connecting parts, the front side of the cab module has a mounting frame, the protrusions are arranged on the mounting frame. The guide connection structure also includes a first connecting member, the first connecting member extends into the connecting part and the protrusions.

[0014] In these embodiments, connecting parts extending outward are provided at both ends of the rear side of the front frame module, and grooves are provided on the connecting parts. On the one hand, this will not affect the main structure of the front frame module, and on the other hand, it is convenient for processing. Moreover, both ends of the rear side of the front frame module have connecting parts, and the connecting parts have grooves, so that the front frame module has two guide structures in the width direction, which can improve the assembly accuracy, and after the protrusions and the grooves cooperate with each other, the front frame module can also be effectively restricted from moving in its own width direction. In addition, the first connecting member is extended into the connecting part and the protrusion to connect the front frame module and the cab module together, which, on the one hand, realizes the connection between the two, and on the other hand, there is no need for the first connecting member to pass through the main structure of the front frame module, thereby reducing the impact on the front frame module.

[0015] In some embodiments, the first body module is a cab module, and the second body module is a rear frame module. A first guide portion is provided on the cab module, and a second guide portion is provided on the rear frame module, so that the two can be connected together quickly and accurately.

[0016] In some embodiments, the cab module includes two first cab longitudinal beams that are laterally spaced apart, and the rear frame module includes two first rear frame longitudinal beams that are laterally spaced apart, and the front ends of the two first rear frame longitudinal beams extend between the two first cab longitudinal beams: the first guide portion is a protrusion formed on the inner side of the first cab longitudinal beam, and the second guide portion is a groove formed on the outer side of the first rear frame longitudinal beam.

[0017] In these embodiments, the front end of the rear frame module extends into the rear end of the cab module, and the two are partially overlapped, which is beneficial to improving the structural strength of the vehicle body structure and reducing the probability of the two being split due to factors such as collision. In addition, a protrusion is provided on the inner side of the first cab longitudinal beam, and a groove is provided on the outer side of the first rear frame longitudinal beam. In the process of the front end of the rear frame module extending into the rear end of the cab module, the protrusion can extend into the groove and move along the extension direction of the groove, which can prevent the cab module and the rear frame module from being skewed during the assembly process. In addition, the design of the protrusion and the groove can also increase the connection strength between the cab module and the rear frame module, and reduce the probability of the two moving up and down relative to each other.

[0018] In addition, protrusions are provided on the inner sides of the two first cab longitudinal beams, and grooves are provided on the outer sides of the two first rear frame longitudinal beams, so that guidance can be performed on both sides of the cab module, and the guiding effect is good.

The second connection member is used to connect the overlapping parts of the first cab longitudinal beam and the first rear frame longitudinal beam together, which is conducive to firmly connecting the cab module and the rear frame module.

[0020] In some embodiments, the cross section of the protrusion is rectangular, trapezoidal or T-shaped, and the groove is wrapped around the outside of the protrusion and matches the protrusion. If the cross section of the protrusion is rectangular or trapezoidal, it is convenient to process. If the cross section of the protrusion is T-shaped and the groove matches the protrusion, the probability of the protrusion and the groove being separated from each other can be reduced, which is conducive to the stable connection of the cab module and the rear frame module.

[0021] In some embodiments, the protrusion is inserted into the groove and forms a movable space with the groove wall of the groove, and the guide connection structure further includes a ball, which is movably arranged in the movable space to guide the protrusion to move in the groove. The design of the ball can reduce the friction between the protrusion and the groove, which is conducive to the smooth movement of the protrusion in the groove along the groove, thereby facilitating the rapid installation of the cab module and the rear frame module.

[0022] In some embodiments, the cab module further includes two first cab vertical beams which are laterally spaced apart, the two first cab vertical beams are arranged one by one on the rear sides of the two first cab longitudinal beams and extend upward, and a third guide portion is provided on the first cab vertical beam; the rear frame module further includes two second rear frame longitudinal beams which are laterally spaced apart, the two second rear frame longitudinal beams are located above the two first rear frame longitudinal beams, and a fourth guide portion is provided on the second rear frame longitudinal beam, and the third guide portion and the fourth guide portion can cooperate with each other to guide the cab module and the rear frame module to align with each other at a set position for connection with each other.

[0023] In these embodiments, the rear frame module includes two second rear frame longitudinal beams in addition to the two first rear frame longitudinal beams. The rear frame module is a frame structure with a certain height. Compared with the plate-shaped rear frame, it can enclose a certain impact-resistant storage space, which is convenient for storing components such as batteries. In addition, a fourth guide portion is provided on the second rear frame longitudinal beam, and a third guide portion is provided on the first cab vertical beam of the cab module, so that the cab module and the rear frame module can also be guided and connected through the third guide portion and the fourth guide portion, and the third guide portion and the fourth guide portion are located above the first guide portion and the second guide portion, so that the cab module and the rear frame module can be smoothly approached to each other and connected at the set position.

[0024] In some embodiments, the third guide portion includes a guide slope, which is located at the rear side of the first cab vertical beam and is arranged close to the rear frame module, and the second rear frame longitudinal beam is configured as the fourth guide portion. The structure is simple, and in the case where the rear sides of the two first cab vertical beams are provided with guide slopes, the guide slopes can quickly guide the front end of the rear frame module to be centered and extend into the rear end of the cab module.

[0025] In some embodiments, one of the third guide portion and the fourth guide portion is a groove, and the other is a protrusion. The structure is simple and convenient for processing.

[0026] In some embodiments, the guide connection structure further includes a third connection member, which is inserted into the adjacent second rear frame longitudinal beam and the first cab vertical beam. The third connection member is used to connect the overlapping parts of the first cab vertical beam and the second rear frame longitudinal beam, which is conducive to firmly connecting the cab module and the rear frame module.

[0057] The following will be combined Figures 1 to 12 The vehicle body structure provided by the embodiment of the utility model is introduced.

[0058] A first aspect of the utility model provides a vehicle body structure, which includes at least two vehicle body modules that are independently assembled and a guide connection structure, wherein the guide connection structure includes a first guide portion 410 and a second guide portion 420, wherein the first guide portion 410 is arranged on a first vehicle body module of the two mutually connected vehicle body modules, and the second guide portion 420 is arranged on a second vehicle body module of the two mutually connected vehicle body modules, and the first guide portion 410 and the second guide portion 420 can cooperate with each other to guide the first vehicle body module and the second vehicle body module to align with each other at a set position for connection with each other.

[0059] The body structure provided in this embodiment includes at least two body modules that are assembled independently, and then the at least two body modules are assembled together to form a complete body structure. Compared with the one-piece body structure in the related art, when the body structure needs to be partially upgraded or changed, it is only necessary to upgrade or change the corresponding body module, adjust the production line of the corresponding body module, and keep the rest unchanged, which can greatly reduce the cost of transformation and is conducive to the development of the body structure. In addition, in order to facilitate the assembly of at least two body modules together, a guide connection structure is also designed. Specifically, a first guide portion 410 is set on the first body module of the two body modules connected to each other, and a second connection portion 110 is set on the second body module, so that the first guide portion 410 and the second guide portion 420 can cooperate with each other to guide the two body modules to quickly align their positions to connect together, thereby improving assembly efficiency.

[0060] Furthermore, in some embodiments, one of the first guide portion 410 and the second guide portion 420 is a groove, and the other is a protrusion. The structure is simple and easy to process. In addition, during the assembly process, the protrusion can easily extend into the groove to guide the two body modules.

[0061] It should be noted that there is no specific limitation on the structure of the protrusions and grooves. The protrusions can be in the shape of strips, dots, or special-shaped structures. Similarly, the grooves can be in the shape of strips, dots, or special-shaped structures, as long as the guiding function is met.

[0062] As an example, the groove and the protrusion face each other in the direction in which the first body module and the second body module are connected to each other. During assembly, the first body module and the second body module can be brought close to each other by directly referring to the positions of the protrusion and the groove, and then the first body module and the second body module are connected together at the set position during the process of the protrusion and the groove cooperating with each other, so that the first body module and the second body module can be quickly connected.

[0063] As an example, the groove is formed as a track groove extending in the direction in which the first body module and the second body module are butted against each other, and the protrusion can be inserted into the track groove in the direction in which the first body module and the second body module are butted against each other. Then, during assembly, the protrusion and the groove can be matched with each other first, and then under the guidance of the protrusion and the groove, the first body module and the second body module continue to approach each other until the set position, thereby improving assembly accuracy.

[0064] Furthermore, in some embodiments, the guide connection structure further includes a connecting member, which is used to connect the first guide portion 410 and the second guide portion 420 together at a set position. In the assembly process, after the first guide portion 410 and the second guide portion 420 guide the first body module and the second body module to the set position, the first guide portion 410 and the second guide portion 420 are connected together by the connecting member, thereby realizing the connection of the two body modules, and the assembly is convenient and quick. Moreover, connecting the connecting member to the two guide portions can prevent the two guide portions from relative movement or reverse movement.

[0065] By way of example, the connecting element is a screw, a bolt or a latch.

[0066] Furthermore, in some embodiments, Figure 1 and Figure 2 As shown, the vehicle body structure includes a front frame module 100, a cab module 200 and a rear frame module 300 which are independently assembled. The front frame module 100 is connected to the front end of the cab module 200, and the rear end of the cab module 200 is connected to the rear frame module 300. A guide connection structure may be provided between the front frame module 100 and the cab module 200, and a guide connection structure may also be provided between the cab module 200 and the rear frame module 300, so as to play a guiding role in the assembly process. The guide connection structures at these two positions may be substantially the same or different.

[0067] Here, the body structure is divided into the above three modules as needed. Each module is independent and relatively complete. No traditional tooling, equipment or production line is required for assembly. It can be fixed by just a few bolts. The structure is simple and easy to assemble.

[0068] Regarding the guide connection structure between the front frame module 100 and the cab module 200, further, in some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, the guide connection structure includes a first guide portion 410 and a second guide portion 420. The first guide portion 410 is a groove formed on the rear side of the front frame module 100, and the second guide portion 420 is a protrusion formed on the front side of the cab module 200. The groove and the protrusion face each other and are plugged into each other. The structure is simple and easy to assemble.

[0069] As an example, Figure 3 , Figure 4 and Figure 5As shown, the two ends of the rear side of the front frame module 100 have connecting parts 110 extending outward, and the grooves are arranged on the connecting parts 110. The front side of the cab module 200 has a mounting frame 210, and the protrusions are arranged on the mounting frame 210. The guide connection structure also includes a first connecting member 130, and the first connecting member 130 extends into the connecting part 110 and the protrusions.

[0070] The connecting parts 110 extending outward are arranged at both ends of the rear side of the front frame module 100, and the grooves are arranged on the connecting parts 110. On the one hand, it will not affect the main structure of the front frame module 100, and on the other hand, it is convenient for processing. Moreover, the connecting parts 110 are arranged at both ends of the rear side of the front frame module 100, and the connecting parts 110 are provided with grooves, so that the front frame module 100 has two guide structures in the width direction, which can improve the assembly accuracy, and after the protrusions and the grooves cooperate with each other, the front frame module 100 can also be effectively restricted from moving in its own width direction. In addition, the first connecting member 130 is extended into the connecting part 110 and the protrusion to connect the front frame module 100 and the cab module 200 together, which realizes the connection between the two on the one hand, and on the other hand, it is not necessary to make the first connecting member 130 pass through the main structure of the front frame module 100, thereby reducing the impact on the front frame module 100.

[0071] In a specific application, the first connecting member 130 can penetrate the bottom wall of the groove and extend into the protrusion. The first connecting member 130 can be a bolt or a latch. The first connecting member 130 can be inserted into the connecting portion 110 and the protrusion along the length direction of the vehicle body structure to reduce the probability of damage to the vehicle body structure when it is subjected to a lateral impact. Figure 4 and Figure 5 A plurality of first mounting holes 120 are arranged on the bottom wall of the groove of the connecting portion 110 , and a plurality of second mounting holes 281 are correspondingly arranged on the top of the protrusion, and a plurality of screws are inserted into the second mounting holes 281 through the first mounting holes 120 one by one.

[0072] Of course, in other examples, a protrusion may be provided on the connecting portion 110 , and a groove may be provided on the mounting frame 210 .

[0073] Regarding the guide connection structure between the cab module 200 and the rear frame module 300, further, in some embodiments, as Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the cab module 200 includes two first cab longitudinal beams 220 that are spaced apart in a transverse direction, and the rear frame module 300 includes two first rear frame longitudinal beams 310 that are spaced apart in a transverse direction. The front ends of the two first rear frame longitudinal beams 310 extend between the two first cab longitudinal beams 220. A portion of the guide connection structure is provided at Figure 6The position corresponding to D1 includes a first guide portion 410 and a second guide portion 420 . The first guide portion 410 is a protrusion formed on the inner side of the first cab longitudinal beam 220 , and the second guide portion 420 is a groove formed on the outer side of the first rear frame longitudinal beam 310 .

[0074] In these embodiments, the front end of the rear frame module 300 extends into the rear end of the cab module 200, and the two are partially overlapped, which is beneficial to improving the structural strength of the vehicle body structure and reducing the probability of the two being split due to factors such as collision. In addition, a protrusion is provided on the inner side of the first cab longitudinal beam 220, and a groove is provided on the outer side of the first rear frame longitudinal beam 310. In the process of the front end of the rear frame module 300 extending into the rear end of the cab module 200, the protrusion can extend into the groove and move along the extension direction of the groove, which can prevent the cab module 200 and the rear frame module 300 from being skewed during the assembly process. In addition, the design of the protrusion and the groove can also increase the connection strength of the cab module 200 and the rear frame module 300, and reduce the probability of the two moving up and down relative to each other.

[0075] In addition, protrusions are provided on the inner sides of the two first cab longitudinal beams 220, and grooves are provided on the outer sides of the two first rear frame longitudinal beams 310, so that guidance can be performed on both sides of the cab module 200, and the guiding effect is good.

[0076] As an example, Figure 7 As shown, the cross section of the protrusion is trapezoidal, and the groove wraps around the outside of the protrusion and matches the protrusion, which is convenient for processing.

[0077] As an example, Figure 8 As shown, the cross section of the protrusion is T-shaped, and the groove matches the protrusion, which can reduce the probability of the protrusion and the groove being separated from each other, and is conducive to the stable connection between the cab module 200 and the rear frame module 300.

[0078] As an example, Fig. 9 As shown, the protrusion is inserted into the groove and forms a movable space with the groove wall of the groove. The guide connection structure also includes a ball 430, which is movably arranged in the movable space to guide the protrusion to move in the groove. The design of the ball 430 can reduce the friction between the protrusion and the groove, which is conducive to the smooth movement of the protrusion in the groove along the groove, thereby facilitating the rapid installation of the cab module 200 and the rear frame module 300.

[0079] Furthermore, if Figure 7 , Figure 8 and Fig. 9As shown, the guide connection structure further includes a second connection member 290, which is inserted into the adjacent first cab longitudinal beam 220 and the first rear frame longitudinal beam 310. The second connection member 290 is used to connect the overlapping parts of the first cab longitudinal beam 220 and the first rear frame longitudinal beam 310, which is conducive to firmly connecting the cab module 200 and the rear frame module 300.

[0080] In a specific application, the second connecting member 290 may be a bolt or a latch. The second connecting member 290 may be inserted into the first cab longitudinal beam 220 and the first rear frame longitudinal beam 310 along the width direction of the vehicle body structure, thereby reducing the probability of the rear side of the vehicle body structure being damaged by impact. Figures 6 to 8 A plurality of third mounting holes 282 are provided on the first cab longitudinal beam 220, and a plurality of fifth mounting holes 351 are correspondingly provided on the first rear frame longitudinal beam 310. There are a plurality of screws, which pass through the third mounting holes 282 and are inserted into the fifth mounting holes 351 one by one.
