[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0028] As Figure 1 and Figure 2 shown, the embodiment of the present application provides a connection structure between a vehicle body and a vehicle frame, including a vehicle body 100, a vehicle frame 200, and a cantilever assembly 300. The vehicle body 100 is disposed on the vehicle frame 200 and is rigidly connected to the vehicle frame 200. Compared with the soft connection in the prior art, the rigid connection between the vehicle body 100 and the vehicle frame 200 can improve the bending stiffness and torsional stiffness of the whole formed by the connection of the vehicle body 100 and the vehicle frame 200. The cantilever assembly 300 is fixedly disposed on the vehicle frame 200 and encloses a cavity 400 with the vehicle frame 200, and the cantilever assembly 300 is rigidly connected to the vehicle body 100. This structure can further improve the rigidity of the whole formed by the connection of the vehicle body 100, the vehicle frame 200, and the cantilever assembly 300, that is, improve the rigidity of the connection structure between the vehicle body and the vehicle frame.

[0029] Optionally, the cantilever assembly 300 can be fixedly disposed on the vehicle frame 200 by welding, or the cantilever assembly 300 can also form an integral structure with the vehicle frame 200 by an integral molding process.

[0030] In the embodiment of the present application, the rigid connection between the vehicle body 100 and the vehicle frame 200 improves the strength and stiffness of the whole formed by their connection, so that the bending and torsional stiffness of the whole vehicle are improved. The cantilever assembly 300 fixedly disposed on the vehicle frame 200 encloses a cavity 400 with the vehicle frame 200 and is rigidly connected to the vehicle body 100, which can further improve the strength and rigidity of the connection structure between the vehicle body and the vehicle frame, thereby further improving the bending and torsional stiffness of the whole vehicle and improving the safety performance of the whole vehicle. It can be seen that the embodiment of the present application can solve the problem in the prior art that the soft connection between the vehicle body and the vehicle frame results in poor overall rigidity after connection and affects the safety performance of the whole vehicle.

[0031] The vehicle body 100 and the vehicle frame 200 can be rigidly connected by a first threaded connector 500. The first threaded connector 500 includes a first bolt and a first nut adapted to the first bolt.

[0032] The vehicle body 100 and the vehicle frame 200 may be provided with 20 - 24 hard connection points, and the hard connection points achieve the hard connection between the vehicle body 100 and the vehicle frame 200 by cooperating with the first threaded connector 500.

[0033] The hard connection points include a first mounting hole corresponding to the vehicle body 100 and cooperating with the first threaded connector 500, and a second mounting hole provided on the vehicle frame 200 and cooperating with the first threaded connector 500. A set of corresponding first mounting hole and second mounting hole cooperate with the same first threaded connector 500. The 20 - 24 hard connection points mean that there are 20 - 24 sets of corresponding first mounting holes and second mounting holes on the vehicle body 100 and the vehicle frame 200.

[0034] During the assembly process of the vehicle body 100 and the vehicle frame 200, it is necessary to first align each set of corresponding first mounting holes and second mounting holes of the vehicle body 100 and the vehicle frame 200 so that the first bolt connector 500 can pass through a set of corresponding first mounting holes and second mounting holes. It should be noted that a set of corresponding first mounting holes and second mounting holes refer to the first mounting hole and the second mounting hole that cooperate with the same first threaded connector 500.

[0035] Therefore, in the embodiment of the present application, the vehicle body 100 may be provided with a first positioning space, and the cantilever assembly 300 may be provided with a second positioning space. Both the first positioning space and the second positioning space are used for positioning and cooperating with the positioning structure 700. During the assembly process of the vehicle body 100 and the vehicle frame 200, when both the first positioning space and the second positioning space are in positioning cooperation with the positioning structure 700, the first mounting holes and the second mounting holes are aligned and distributed one by one, so that the first threaded connector 500 can pass through a set of aligned and distributed first mounting holes and second mounting holes to connect the vehicle body 100 and the vehicle frame 200.

[0036] In this case, before connecting the vehicle body 100 and the vehicle frame 200 through the first threaded connector 500, the alignment of each set of corresponding first mounting holes and second mounting holes can be achieved through the cooperation of the positioning structure 700 with the first positioning space and the second positioning space, thereby facilitating the connection of the vehicle body 100 and the vehicle frame 200 by the first threaded connector 500.

[0037] In addition, on the premise of assisting in enclosing the cavity 400 and improving the strength and stiffness, the cantilever assembly 300 can also assist in completing the alignment work before connecting the vehicle body 100 and the vehicle frame 200, so that the cantilever assembly 300 has the effect of multi - purpose use and simplifies the connection structure between the vehicle body and the vehicle frame.

[0038] Optionally, the first positioning space may be a positioning groove, and the second positioning space may be a second positioning hole.

[0039] Optionally, the first positioning space may include a first positioning hole, and the second positioning space may include a second positioning hole. Such a structure facilitates the processing and production of the first positioning space and the second positioning space, and also facilitates the cooperation between the first positioning space and the second positioning space and the positioning structure 700.

[0040] The positioning structure 700 may include a columnar section and a conical section distributed along its own or axial direction. The tip of the conical section faces away from the columnar section. Before assembling the vehicle body 100 and the vehicle frame 200, the columnar section of the positioning structure 700 may be connected to the tooling trolley, or may be installed on the assembly base of the vehicle body 100 and the vehicle frame 200 (such as the ground or a special workbench for assembly). The conical section of the positioning structure 700 faces the vehicle body 100.

[0041] During the assembly process, the vehicle body 100 is connected to the sling, the vehicle frame 200 is placed on the special tooling trolley, and the vehicle body 100 is placed on the vehicle frame 200 through the sling. During the placement process, the conical section of the positioning structure 700 sequentially passes through the second positioning hole and the first positioning hole, so that the corresponding sets of first mounting holes and second mounting holes are aligned. Since the total length of the vehicle frame 200 is more than 5 meters and it is severely deformed, therefore, positioning and guiding through the positioning structure 700 can guide each corresponding set of first mounting holes and second mounting holes of the vehicle body 100 and the vehicle frame 200 together in advance, ensuring that the vehicle body 100 can stably fall onto the vehicle frame 200 within 50 mm before the vehicle body 100 reaches the bottom, and aligning the positions of each corresponding set of first mounting holes and second mounting holes, guiding the mounting holes of the vehicle body 100 and the vehicle frame 200 from rough positioning to precise positioning, ensuring that the bolt connection can be directly concentric and smoothly installed and connected without manual intervention.

[0042] It should be noted that when the conical section of the positioning structure 700 cooperates with the first positioning hole of the vehicle body 100, the corresponding sets of first mounting holes and second mounting holes of the vehicle body 100 and the vehicle frame 200 achieve rough positioning. When the columnar section of the positioning structure 700 cooperates with the first positioning hole of the vehicle body 100, the corresponding sets of first mounting holes and second mounting holes of the vehicle body 100 and the vehicle frame 200 achieve precise positioning.

[0043] In an optional embodiment, the apertures of the first positioning hole and the second positioning hole may be the same.

[0044] In a preferred embodiment, the aperture of the first positioning hole and the aperture of the second positioning hole may be different. For example, the aperture of the first positioning hole may be smaller than the aperture of the second positioning hole, or the aperture of the first positioning hole may be larger than the aperture of the second positioning hole. In such a structure, the requirement for the position accuracy of the first positioning hole and the second positioning hole can be reduced, facilitating processing and production.

[0045] In the above embodiments, the vehicle frame 200 is provided with a cantilever assembly 300. Optionally, the cantilever assembly 300 may include a first cantilever 310 and a second cantilever 320. The first ends of the first cantilever 310 and the second cantilever 320 can be fixedly connected to the vehicle frame 200 by means such as welding and bolt connection. The second ends of the first cantilever 310 and the second cantilever 320 extend away from the vehicle frame 200, so that the first cantilever 310, the second cantilever 320 and the vehicle frame 200 enclose a cavity 400.

[0046] Of course, in other alternative embodiments, the cantilever assembly 300 may further include a connecting arm, with one end of the connecting arm connected to the first cantilever 310 and the other end connected to the second cantilever 320.

[0047] In a further technical solution, the height of one end of the cavity 400 adjacent to the vehicle frame 200 can be greater than the height of the end of the cavity 400 away from the vehicle frame 200. This structure helps to improve the connection stability between the vehicle frame 200 and the cantilever assembly 300.

[0048] It should be noted that the height of the end of the cavity 400 adjacent to the vehicle frame 200 refers to the distance between the ends of the first cantilever 310 and the second cantilever 320 adjacent to the vehicle frame 200, and the height of the end of the cavity 400 away from the vehicle frame 200 refers to the distance between the ends of the first cantilever 310 and the second cantilever 320 away from the vehicle frame 200.

[0049] There are various structures for realizing different heights at both ends of the cavity 400. In an alternative embodiment, there may be an angle between the first cantilever 310 and the second cantilever 320, and the angle is not zero.

[0050] In another alternative embodiment, along the direction from the first end to the second end of the second cantilever 320, the second cantilever 320 may include a first bent section 321 and a second bent section 322. The first bent section 321 is inclined with respect to the first cantilever 310 and is inclined towards the direction close to the first cantilever 310, and the second bent section 322 is parallel to the first cantilever 310, so that the height of the end of the cavity 400 adjacent to the vehicle frame 200 can be greater than the height of the end of the cavity 400 away from the vehicle frame 200.

[0051] In a further technical solution, the cantilever assembly 300 and the vehicle body 100 can be rigidly connected by a second threaded connector 600. The second threaded connector 600 includes a second bolt and a second nut adapted to the second bolt. This structure can further improve the connection strength between the vehicle body 100 and the vehicle frame 200.

[0052] Based on the above connection structure between the vehicle body and the vehicle frame, an embodiment of the present application further provides a vehicle, which includes the above connection structure between the vehicle body and the vehicle frame. Since the vehicle has the above connection structure between the vehicle body and the vehicle frame, for the beneficial effects brought by the connection structure between the vehicle body and the vehicle frame, please refer to the above content and will not be elaborated here.

[0053] The vehicle can be a fuel vehicle or a new energy vehicle. The vehicle can be an off-road vehicle. Currently, the market demand for off-road vehicles is increasing, and the application range is also expanding. It can be used as a means of transportation on weekdays and for outdoor off-road relaxation on weekends and holidays. At the same time, it is popular among individual merchants, off-road enthusiasts, modification enthusiasts, outdoor travel enthusiasts, engineering construction, etc. Of course, the vehicle can also be a pickup truck, a commercial minibus, a motorhome, etc. The present application does not limit this.

[0054] The vehicle may further include a cargo box, which can be integrally provided with the vehicle body 100. Optionally, the cargo box and the vehicle body 100 can be integrally provided by welding, or can be connected as a whole by a third threaded connection member. The third threaded connection member includes a third bolt and a third nut adapted to the third bolt.

[0055] The integral setting of the cargo box and the vehicle body 100 strengthens the connection between the cargo box and the vehicle body 100. On the one hand, there are no obvious gaps in the appearance of the vehicle, which improves the aesthetics of the vehicle, simplifies the manufacturing process, reduces costs and weight. On the other hand, a stronger and more compact connection is formed between the cargo box and the vehicle body 100, which improves the connection stability of the cargo box and the collision safety and handling stability of the vehicle body 100.
