Description

TECHNICAL FIELD

[0001] The utility model relates to a vehicle, and specifically provides a vehicle body assembly and vehicle. BACKGROUND

[0002] In the traditional vehicle design, a structure similar to shark fin is often arranged on the top of the vehicle to accommodate and install a radio antenna, so as to optimize the signal receiving effect. With the development of wireless communication technology, the radio antenna is gradually moved to the rear window area of the vehicle, and the traditional shark fin structure loses its function and evolves into a purely decorative design element.

[0003] The rapid development of automatic driving technology drives the increasing demand for perception hardware. The shark fin structure is re-endowed with functions due to its advantages of being located at the top rear of the vehicle. It can now accommodate key devices such as high-definition cameras, millimeter wave radars, and global navigation satellite system receivers, thereby improving the reliability and accuracy of the automatic driving system, and the design gradually changes from decorative to functional. Modern shark fins need to accommodate various hardware and wiring systems, resulting in significant changes in size and shape.

[0004] The traditional shark fin is fixed by a single bolt, which is suitable for early designs with smaller sizes, but cannot meet modern needs. The new shark fin adopts a multi-point installation method. However, the multi-point installation method also increases technical challenges, as the bolt connection requires sufficient installation space on the inside of the vehicle body. The increase in installation points leads to an increase in the need for avoidance space, which may increase the installation difficulty in compact vehicles or even require changes to the vehicle body structure. Optimizing the installation method in the limited space has become one of the technical difficulties in shark fin design.

[0005] Therefore, there is an urgent need in the art for a vehicle body assembly and vehicle to solve the above problems. SUMMARY

[0006] The utility model aims to solve the above technical problems, i.e., to solve the connection problem between the existing vehicle body and shark fin.

[0007] In a first aspect, the utility model provides a vehicle body assembly, which comprises:

[0008] A main assembly comprising a first vehicle body part and a first connecting part, the first connecting part being fixedly connected to the first vehicle body part;

[0009] An accessory assembly comprising a second connecting part and a functional part fixedly arranged on the second connecting part, the second connecting part being capable of clamping the first connecting part, so that the accessory assembly is connected to the main assembly.

[0015] In the specific embodiment of the vehicle body assembly, the second vehicle body member comprises a second connecting area, and the first connecting area and the second connecting area are at least partially weldedly connected.

[0016] In the specific embodiment of the vehicle body assembly, the welding area, the first connecting area and the second connecting area are at least partially sequentially stacked and weldedly connected into a three-layer welding structure.

[0017] In the specific embodiment of the vehicle body assembly, the main assembly comprises a plurality of the first connecting members, and the auxiliary assembly comprises a plurality of the second connecting members, and the first connecting members and the second connecting members are one-to-one correspondingly arranged.

[0018] In the second aspect, the utility model provides a kind of vehicle, which comprises the vehicle body assembly described above.

[0019] In the specific embodiment of the vehicle, the auxiliary assembly is a shark fin assembly.

[0020] With the above technical solution, the first vehicle body member is provided with the first connecting member, the auxiliary assembly comprises the second connecting member, and the second connecting member can connect the first connecting member to connect the auxiliary assembly to the first vehicle body member.

[0021] Further, the first vehicle body member can isolate the dry area and the wet area of the vehicle body assembly, the dry area is the interior of the vehicle, and the wet area is the exterior of the vehicle. The first connecting member and the auxiliary assembly are both arranged on the wet area side of the first vehicle body member. This structural design can effectively prevent the connection part between the main assembly and the auxiliary assembly from causing leakage between the wet area and the dry area, thereby improving the sealing performance of the vehicle body assembly.

[0032] To solve the problem of connecting the vehicle body and the shark fin, the embodiment discloses a vehicle. The vehicle comprises a vehicle body assembly, and the vehicle body assembly comprises a main body assembly and an auxiliary assembly.

[0033] Referring to Figure 1 , the main body assembly comprises a first vehicle body piece 11, a second vehicle body piece 13 and a first connecting piece 12. The first vehicle body piece 11 and the second vehicle body piece 13 are both sheet metal structures. The first vehicle body piece 11 can isolate the dry area and the wet area of the vehicle body assembly. The dry area is specifically the inside of the vehicle, that is Figure 1 The lower left side of the first vehicle body piece 11 in the dry area of the vehicle; the wet area is specifically the outside of the vehicle, that is Figure 1 The upper right side of the first vehicle body piece 11 in the wet area of the vehicle. When precipitation occurs outside the vehicle, or when the vehicle is washed, the wet area is in contact with water. The first vehicle body piece 11 isolates the wet area, which can prevent water from entering the dry area inside the vehicle. The first connecting piece 12 is arranged on the wet area side of the first vehicle body piece 11, so that the first connecting piece 12 can connect the auxiliary assembly outside the vehicle. The second vehicle body piece 13 is located on the dry area side of the first vehicle body piece 11.

[0034] Referring to Figure 2 , the first connecting piece 12 and the second vehicle body piece 13 are both welded to the first vehicle body piece 11. Specifically, the first connecting piece 12 comprises three welding areas, namely a first welding point 14, a second welding point 15 and a third welding point 16. The first vehicle body piece 11 comprises a first connecting area. The three welding areas of the first connecting piece 12 are welded to the first connecting area of the first vehicle body piece 11. The second vehicle body piece 13 comprises a second connecting area, and the second connecting area is welded to the first connecting area of the first vehicle body piece 11.

[0035] In the assembling process, the first connecting member 12 and the first vehicle body member 11 are welded at the second welding point 15 and the third welding point 16. Then, the second vehicle body member 13 is welded to the first vehicle body member 11. The first connecting member 12, the first vehicle body member 11 and the second vehicle body member 13 are sequentially stacked at the first welding point 14, and a three-layer welding structure is formed by welding, which will be described in detail in Figure 1 The first vehicle body member 11 and the second vehicle body member 13 form a hollow beam structure, in other words, the first vehicle body member 11 and the second vehicle body member 13 form the outer wall of the hollow beam structure. Further, the cross-sectional shape of the hollow beam structure is approximately triangular to enhance the structural strength of the hollow beam structure. Further, the second vehicle body member 13 is arranged as one of the oblique sides of the triangle. The ends of the first connecting member 12 and the second vehicle body member 13 are welded to the two sides of the first vehicle body member 11, respectively, to form a three-layer welding structure. This arrangement can improve the support effect of the first connecting member 12, and further improve the support effect of the accessory assembly.

[0036] It should be noted that the connection structure of the first connecting member 12, the first vehicle body member 11 and the second vehicle body member 13, although the first connecting member 12 and the first vehicle body member 11 in the embodiment are provided with three welding points, two of which are two-layer welding points between the first connecting member 12 and the first vehicle body member 11, and the other is a three-layer welding point between the first connecting member 12, the first vehicle body member 11 and the second vehicle body member 13, but this arrangement is not a limitation of the present application. Within the scope of the present application, those skilled in the art can also use other arrangements in other embodiments, for example, the first connecting member 12 and the first vehicle body member 11 can be provided with other number of welding points, the number of two-layer welding points and the number of three-layer welding points can be changed, etc. These changes do not deviate from the basic principles of the present application, and therefore fall within the scope of the present application.

[0037] The accessory assembly is specifically a shark fin assembly. The main structure of the shark fin assembly is the same as that of the shark fin antenna of the prior art, and its specific structure will not be described here.

[0038] It should be noted that although the accessory assembly in the embodiment is a shark fin assembly, this arrangement is not a limitation of the present application. Within the scope of the present application, those skilled in the art can also use other arrangements in other embodiments, for example, the accessory assembly can also be arranged as other accessory structures on the vehicle body, which does not deviate from the basic principles of the present application, and therefore falls within the scope of the present application.

[0039] Continuing to refer to Figure 1The accessory assembly includes a functional part, a second connecting part 21 and a cover plate 22. The functional part is a part arranged in the shark fin assembly. In an embodiment, the functional part is specifically a radio antenna, which optimizes signal reception by the top position of the shark fin. In other embodiments, the functional part is specifically a sensor and sensing hardware of an auxiliary driving system. The sensing hardware includes a high-definition camera, a millimeter wave radar, a global navigation satellite system receiver, a communication device, etc.

[0040] It should be noted that, although the functional part in the present embodiment is a radio antenna, a sensor and sensing hardware, this arrangement is not a limitation of the present application. Those skilled in the art can use other arrangements in other embodiments without departing from the principles of the present application. Such arrangements do not deviate from the basic principles of the present application and thus fall within the scope of the present application.

[0041] The second connecting part 21 is fixedly connected to the cover plate 22 (only the cover plate 22 is shown in the figure, and other structures of the accessory assembly are not shown). The second connecting part 21 is provided with an outwardly extending plug-in part 211. The first connecting part 12 is provided with a plug-in hole 121. The plug-in part 211 can extend into the plug-in hole 121, so that the second connecting part 21 is clamped to the first connecting part 12, and then the accessory assembly is connected to the main body assembly. Further, when the plug-in part 211 extends into the plug-in hole 121, the plug-in part 211 is spaced apart from the first body part 11, in other words, the plug-in part 211 does not contact the first body part 11. The present embodiment provides the plug-in hole 121 on the first connecting part 12, instead of the structure of providing the plug-in hole 121 on the vehicle body, which can avoid the leakage between the dry area and the wet area caused by the clamping structure penetrating through the vehicle body, and improve the sealing effect of the clamping structure.

[0042] It should be noted that, although the first connecting part 12 is provided with the plug-in hole 121, and the second connecting part 21 is provided with the outwardly extending plug-in part 211, which can extend into the plug-in hole 121, so that the second connecting part 21 is clamped to the first connecting part 12. However, this arrangement is not a limitation of the present application. Those skilled in the art can use other arrangements in other embodiments without departing from the principles of the present application. For example, the first connecting part 12 and the second connecting part 21 can also be connected by adhesion, welding, screwing, etc. These changes do not deviate from the basic principles of the present application and thus fall within the scope of the present application.

[0043] Further, the main body assembly can include a plurality of first connecting pieces 12, and the accessory assembly includes a plurality of second connecting pieces 21, and the first connecting pieces 12 and the second connecting pieces 21 are arranged one by one. In the embodiment, the main body assembly includes two first connecting pieces 12. Through the plurality of clamping structures, the accessory assembly is connected to the main body assembly, and the stability of the connecting structure can be improved to adapt to the shark fin structure of large size.

[0044] Further, the second vehicle body part 13 can be connected with a support 17, and the support 17 can be used to install a sunshade curtain. Such a support 17 will block the position corresponding to the first connecting piece 12. If the bolt connection is used, the connecting tool cannot be avoided. The clamping structure is used in the embodiment, and the connecting tool is not needed, the problem of avoiding space is solved, and the connection structure of the accessory assembly and the main body assembly is more convenient.

[0045] So far, the technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the utility model is obviously not limited to these specific embodiments. On the premise of not deviating from the principles of the utility model, those skilled in the art can make equivalent changes or replacements to the related technical features, and the technical schemes after the changes or replacements will all fall within the protection scope of the utility model.
