[0048] In order to solve the technical problems existing in the prior art, the present application provides a vehicle body charging structure and a vehicle. The technical solution provided by the present application will be explained and illustrated in conjunction with embodiments below.

[0049] See also Figures 1 to 4 In one aspect, the present application provides a vehicle body charging structure, comprising a vehicle body side member 1 and a charging base assembly. The vehicle body side member 1 is provided with a mounting opening 11, and a first connecting portion 12 and a second connecting portion 13 are provided around the mounting opening 11. The charging base assembly is selected from a single-charging assembly 2 and a multi-charging assembly 3, and either the single-charging assembly 2 or the multi-charging assembly 3 is selectively installed. The single-charging assembly 2 can be mounted to the vehicle body side member 1 via the first connecting portion 12, and the multi-charging assembly 3 can be mounted to the vehicle body side member 1 via the second connecting portion 13.

[0050] It should be noted that if Figure 5As shown, the present application also includes a protective sheet metal 4, which is installed on one side of the vehicle body side beam 1. The protective sheet metal 4 is provided with a placement groove, which corresponds to the installation port 11 and is used to place a single charging assembly 2 or a part of the multi-charging assembly 3. It should be noted that in this embodiment, the single charging assembly 2 is a slow charging seat or a fast charging seat, and the specific type is selected according to the actual setting requirements. The multi-charging assembly 3 is integrated with a slow charging seat and a fast charging seat to meet different charging scenarios of the vehicle.

[0051] In the present application, it is only necessary to set the first connecting portion 12 and the second connecting portion 13 on the vehicle body side beam 1, and then the single charging assembly 2 or the multi-charging assembly 3 can be installed according to actual needs, so that the present application can adapt to the needs of different charging scenarios; the vehicle body charging structure provided by the present application can broaden the usage scenarios of existing vehicle models, and there is no need to change the structure of other components of the vehicle body, thereby reducing the cost of vehicle modification while ensuring the safety and aesthetics of the vehicle body.

[0052] like Figure 1 and Figure 3 As shown, in some application scenarios of the present application, the single-charge assembly 2 is installed on the side beam 1 of the vehicle body. The single-charge assembly 2 includes a first bracket 22 and a single-charge charging seat 21. In this embodiment, the single-charge charging seat 21 can be a fast-charge charging seat or a slow-charge charging seat to meet the choices of different customers for the type of single-charge charging seat. The single-charge charging seat 21 is installed on the first bracket 22, and the first bracket 22 has a first extension portion 221, a second extension portion 222 and a third extension portion 223 extending outward from the edge of the first bracket 22. Corresponding to the above-mentioned extension portion, the first connecting portion 12 includes a first positioning area 121, a second positioning area 122 and a third positioning area 123 arranged around the mounting port 11. The first extension portion 221, the second extension portion 222 and the third extension portion 223 are respectively fixedly installed in the first positioning area 121, the second positioning area 122 and the third positioning area 123 through the fixing parts 5, so that there are three fixed support points between the first bracket 22 and the vehicle body side beam 1, which can ensure a stable connection between the first bracket 22 and the vehicle body side beam 1.

[0053] In detail, such as Figure 7 and Figure 8As shown, the first bracket 22 includes a first support plate 225, and the first extension portion 221, the second extension portion 222, and the third extension portion 223 are all located around the first support plate 225. The first support plate 225 is provided with a mounting hole for mounting the single-charger charging stand 21, and four first fixing holes are arranged in a rectangular pattern around the mounting hole. The single-charger assembly 2 has second fixing holes corresponding to the four first fixing holes, and the single-charger charging stand 21 is mounted on the first support plate 225 by bolts. It can be understood that this embodiment only provides one specific structure of the first bracket 22. In other embodiments, the specific structure of the first bracket 22 can be designed according to the vehicle body structure, and this application does not impose any restrictions on this.

[0054] like Figure 3 and Figures 6 to 9 As shown, first mounting holes 14 are respectively defined in the first positioning area 121, the second positioning area 122, and the third positioning area 123. Second mounting holes 224 corresponding to the first mounting holes 14 are respectively defined in the first extension 221, the second extension 222, and the third extension 223. The fixing member 5 includes fixing bolts 51 passing through the corresponding first mounting holes 14 and second mounting holes 224, and fixing nuts 52 connected to the fixing bolts 51. The fixing bolts 51 passing through the first mounting holes 14 and the second mounting holes 224 are threadedly secured to the fixing nuts 52, thereby completing the fixed connection between the first bracket 22 and the side member 1.

[0055] In this application, the installation environment between the first bracket 22 and the vehicle body side rail 1 is narrow, and when the fixing bolt 51 and the fixing nut 52 are installed together, the fixing nut 52 needs to be restricted from rotating so that the fixing bolt 51 can be screwed into the fixing nut 52, which causes many inconveniences. To this end, in this embodiment, the fixing nuts 52 are welded to the corresponding first positioning area 121, second positioning area 122, and third positioning area 123, respectively, and the threaded hole of each fixing nut 52 corresponds to the first mounting hole 14 in the area where it is located.

[0056] During the actual installation process, the first extension portion 221, the second extension portion 222 and the third extension portion 223 are respectively placed on the first positioning area 121, the second positioning area 122 and the third positioning area 123, and the second mounting hole 224 is aligned with the corresponding first mounting hole 14. Finally, the three fixing bolts 51 are respectively passed through the corresponding second mounting holes 224 and the first mounting holes 14 and then screwed into the threaded holes of the corresponding fixing nuts 52. When the first bracket 22 is installed on the vehicle body side beam 1, it is only necessary to screw the fixing bolts 51 without operating the fixing nuts 52, thereby improving the convenience and efficiency of installation.

[0057] Furthermore, if Figure 3 and Figure 7As shown, the vehicle body side member 1 is further provided with a positioning member 16, and the single charging assembly 2 is provided with a first mating member 227 that cooperates with the positioning member 16. It can be understood that the single charging assembly 2 cooperates with the first mating member 227 to provide pre-limiting during the installation of the single charging assembly 2, facilitating subsequent installation and fixation.

[0058] In a specific example provided in this application, Figure 3 As shown, the positioning member 16 includes a hook provided on the vehicle body side beam 1, the hook is located in the installation opening 11, and the opening direction of the hook is the first direction; Figure 10 and Figure 11 As shown, the first fitting member 227 includes a hanger extending along a second direction, and the second direction and the first direction are two directions perpendicular to each other. When fixing the first bracket 22 to the vehicle body side beam 1, the hanger is first placed on the hook to define the initial position of the first bracket 22 and the vehicle body side beam 1, so as to facilitate the subsequent adjustment of the relative position between the first bracket 22 and the vehicle body side beam 1 along the first direction and the second direction before fixing. It should be noted that in other embodiments, a limit block is provided at the end of the hanger away from the first bracket 22 to define the relative position between the hook and the hanger. Therefore, this embodiment provides a specific structure of the positioning member 16 and the first fitting member 227, but this application does not limit the specific structure of the positioning member 16 and the first fitting member 227. Specific structures that can achieve the initial installation and positioning of the first bracket 22 and the vehicle body side beam 1 are all within the scope of protection of this application.

[0059] In some application scenarios of this application, such as Figure 2 As shown, the multi-charge assembly 3 is installed on the vehicle body side beam 1. Figure 4 and Figure 12 The multi-charger assembly 3 includes a multi-charger charging base 32 and a second bracket 31. The multi-charger charging base 32 is installed on the second bracket 31. The second bracket 31 has a first fixing portion 301, a second fixing portion 302, a third fixing portion 303, and a fourth fixing portion 304. Correspondingly, the second connecting portion 13 includes a first positioning area 121, a second positioning area 122, a third positioning area 123, and a fourth positioning area 124.

[0060] It is worth mentioning that the second connection portion 13 and the first connection portion 12 share a common area. In this embodiment, the first positioning area 121, the second positioning area 122, and the third positioning area 123 are common areas of the first connection portion 12 and the second connection portion 13. On this basis, the second connection portion 13 also includes a fourth positioning area 124. In this embodiment, by providing the first positioning area 121, the second positioning area 122, the third positioning area 123, and the fourth positioning area 124 on the vehicle body side beam 1, the present application can be combined in different ways to form the first connection portion 12 and the second connection portion 13, so that the first connection portion 12 and the second connection portion 13 are respectively used to cooperate with the installation of the single charging assembly 2 or the multi-charging assembly 3. It should be noted that, in other embodiments, the number and positions of the positioning areas included in the first connection part 12 and the second connection part 13 are not limited to this. The first connection part 12 and the second connection part 13 may also have other common areas, such as the second positioning area 122, the third positioning area 123 and the fourth positioning area 124, the first positioning area 121, the third positioning area 123 and the fourth positioning area 124, etc. Of course, the first connection part 12 and the second connection part 13 may also be completely separated so that there is no common area between the two. The specific selection can be made according to actual design requirements and is not limited here.

[0061] like Figures 12 to 14 As shown, in a specific example provided herein, the second bracket 31 includes a second support plate 324, a second right bracket 312, and a second left bracket 311. The second support plate 324 is connected to the multi-charger charging station 32, and the second right bracket 312 and the second left bracket 311 are used to connect the second support plate 324 to the vehicle body side rail 1. The first fixing portion 301 and the second fixing portion 302 are located on the second right bracket 312, and the second right bracket 312 is fixedly connected to the second support plate 324 via bolts. The third fixing portion 303 and the fourth fixing portion 304 are located on the second left bracket 311, and the second left bracket 311 is fixedly connected to the second support plate 324 via bolts. Specifically, in this embodiment, the second right bracket 312 and the second left bracket 311 are located on either side of the mounting opening 11, which can reduce obstruction of the area where the mounting opening 11 is located, allowing sufficient space to accommodate the larger multi-charger charging station 32 in existing single-charge port vehicles. In addition, the arrangement of the second right bracket 312 and the second left bracket 311 can also extend the second bracket 31 to the corresponding position of the second connecting portion 13, so that the multi-charging assembly 3 can adapt to the original installation position of the upper vehicle body side beam 1, facilitating the installation of the multi-charging assembly 3.

[0062] Specifically, if Figure 4 As shown, in a specific example provided in this application, the first positioning area 121, the second positioning area 122, the third positioning area 123 and the fourth positioning area 124 are respectively provided with a first connection hole 15; further reference is made to Figure 15The first fixing part 301, the second fixing part 302, the third fixing part 303 and the fourth fixing part 304 are respectively provided with a second connecting hole 305; the fixing member 5 includes a fixing bolt 51 passing through the corresponding first connecting hole 15 and the second connecting hole 305, and a fixing nut 52 fixedly connected to the fixing bolt 51.

[0063] like Figure 6 and Figure 12 As shown, the multi-charging assembly 3 is provided with a second mating piece 321 that cooperates with the positioning piece 16 on the vehicle body side beam 1. The cooperation between the multi-charging assembly 3 and the second mating piece 321 can provide pre-limiting during the installation of the multi-charging assembly 3, facilitating subsequent fixed installation.

[0064] Furthermore, if Figure 4 and Figure 15 and Figure 16 As shown, the second matching member 321 includes a hanging block 322 extending along the second direction, and a stopper 323 is provided at one end of the hanging block away from the multi-charger charging station 32. The second direction and the first direction are two directions perpendicular to each other.

[0065] When installing the multi-charger charging station 32 on the vehicle body side rail 1, the hanging block 322 on the multi-charger charging station 32 is placed on the hook. The stopper 323 on the hanging block 322 is used to limit the sliding of the multi-charger charging station 32, ensuring that the multi-charger charging station 32 is relatively stable when suspended on the vehicle body side rail 1, and facilitating the fixing of the two sides of the multi-charger charging station 32 to the second right bracket 312 and the second left bracket 311, respectively. This embodiment provides a specific structure of the positioning member 16 and the second mating member 321, but this application does not limit the specific structure of the positioning member 16 and the second mating member 321. Specific structures that can achieve the initial installation and positioning of the multi-charger charging station 32 on the vehicle body side rail 1 are within the scope of protection of this application.

[0066] In some embodiments of the present application, a vehicle is provided, including the above-mentioned vehicle body charging structure. During actual use, a fast charging station, a slow charging station, or a multi-charging station can be installed according to the selection, so that the vehicle has three charging mode installation options to meet the different needs of users. Because the structure of the vehicle body side beam 1 is modified in this vehicle, a first connecting portion 12 and a second connecting portion 13 are provided on the vehicle body side beam 1 to respectively cooperate with the installation of a single charging assembly 2 or a multi-charging assembly 3. Without changing other structures of the vehicle body, the applicable scenarios of the original single charging station vehicle model can be improved, thereby reducing production costs.

[0067] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention are intended to be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
