[0021] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the specific implementation modes of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation modes of the present invention.

[0022] like Figure 1 and Figure 2 An electric all-terrain vehicle 100 is shown, and the electric all-terrain vehicle 100 includes a frame 11, a body cover 12, a travel assembly 13, a saddle assembly 14, a transmission assembly 15, a power assembly 16, and a battery assembly 17. The frame 11 constitutes the basic framework of the electric all-terrain vehicle 100, and the frame 11 is used to support the body cover 12, the travel assembly 13, the saddle assembly 14, the transmission assembly 15, the power assembly 16, and the battery assembly 17. The body cover 12 is at least partially disposed on the frame 11, and the body cover 12 is used to protect the internal parts of the electric all-terrain vehicle 100. The travel assembly 13 is used to realize the movement of the electric all-terrain vehicle 100. The saddle assembly 14 is at least partially disposed on the frame 11, and the saddle assembly 14 is used for the driver to ride. The power assembly 16 is at least partially disposed on the frame 11, and the power assembly 16 is used to drive the electric all-terrain vehicle 100. Specifically, the power assembly 16 includes a drive motor 161, and the drive motor 161 is connected to at least one of the front wheel 131 and the rear wheel 132 through the transmission assembly 15. The transmission assembly 15 is at least partially disposed on the frame 11, and the transmission assembly 15 is connected to the travel assembly 13. The battery assembly 17 is at least partially disposed on the frame 11, and the battery assembly 17 is used to provide energy to the power assembly 16. Specifically, the battery assembly 17 is electrically connected to the drive motor 161, and the battery assembly 17 is used to provide electrical energy to the drive motor 161. In order to clearly illustrate the technical solution of the present application, the following is also defined. Figure 1 In the description of the present application, the length direction of the electric all-terrain vehicle 100 refers to the front-to-back direction, the width direction of the electric all-terrain vehicle 100 refers to the left-right direction, and the height direction of the electric all-terrain vehicle 100 refers to the up-down direction.

[0023] like Figure 3As shown, the frame 11 includes a first longitudinal frame 111 and a second longitudinal frame 112 arranged above the first longitudinal frame 111. Specifically, the first longitudinal frame 111 and the second longitudinal frame 112 are both composed of a plurality of support tubes 1111 distributed along the width direction of the electric all-terrain vehicle 100. Among them, the first longitudinal frame 111 basically constitutes the main supporting part of the chassis of the electric all-terrain vehicle 100, and the second longitudinal frame 112 constitutes the main supporting part of the beam frame of the electric all-terrain vehicle 100, and the first longitudinal frame 111 and the second longitudinal frame 112 are supported by the support tubes 1111 extending basically along the height direction. Therefore, an accommodating space 101 for arranging vehicle parts is formed between the first longitudinal frame 111 distributed basically along the width direction and the second longitudinal frame 112 distributed basically along the width direction, and the first longitudinal frame 111 and the second longitudinal frame 112 can provide support and protection for the parts arranged thereon. More specifically, the transmission assembly 15 and the battery assembly 17 are at least partially located between the first longitudinal frame 111 and the second longitudinal frame 112, and the transmission assembly 15 and the battery assembly 17 are at least partially located in the accommodation space 101. Specifically, the travel assembly is at least partially arranged below the first longitudinal frame, the first longitudinal frame 111 is used to support the transmission assembly 15 and the battery assembly 17, and the second longitudinal frame 112 is used to protect the transmission assembly 15 and the battery assembly 17. The travel assembly 13 includes a front wheel 131 and a rear wheel 132, the front wheel 131 and the rear wheel 132 are at least partially arranged below the first longitudinal frame 111, the drive motor 161 is connected to at least one of the front wheel 131 and the rear wheel 132 through the transmission assembly 15, and the accommodation space 101 is at least partially located between the front wheel 131 and the rear wheel 132, and the accommodation space 101 is used to accommodate body parts. It should be noted that the body parts refer to parts or components such as the drive motor 161, the transmission shaft 151 and the battery assembly 16. It is understandable that the number of support tubes 1111 distributed along the width direction of the first longitudinal frame 111 and the second longitudinal frame 112 can be set to two, three or more. In the present application, the first longitudinal frame 111 and the second longitudinal frame 112 are both configured to be composed of two support tubes 1111 distributed in the width direction, and the two support tubes 1111 are interconnected by a plurality of hollow tubes or solid sheets extending in the width direction, so that the first longitudinal frame 111 and the second longitudinal frame 112 are integrated. This arrangement can ensure the strength of the frame 11 while ensuring the lightweight of the entire vehicle and maximizing the installation space. The body cover 12 is at least partially connected to the first longitudinal frame 111 and the second longitudinal frame 112, so that the body cover 12 is basically arranged around the accommodating space 101.

[0024] like Figure 2As shown, as an implementation, the battery assembly 17 includes a first power battery 171 and a second power battery 172, both of which are at least partially located in the accommodation space 101, and both of which are arranged on the first longitudinal frame 111. A reference plane 102 perpendicular to the height direction of the electric all-terrain vehicle 100 is defined, and the area occupied by the projection of the first longitudinal frame 111 on the reference plane 102 along the height direction is defined as a first projection area, and the area occupied by the projection of the second longitudinal frame 112 on the reference plane 102 along the height direction is defined as a second projection area. Observed from the height direction, both of the first power battery 171 and the second power battery 172 are located in the first projection area, and both of the first power battery 171 and the second power battery 172 are at least partially located outside the second projection area. Specifically, the first power battery 171 and the second power battery 172 are at least partially located on the left and right sides of the second longitudinal frame 112, respectively. Optionally, a longitudinal plane 103 perpendicular to the width direction of the electric all-terrain vehicle 100 and passing through the width center of the electric all-terrain vehicle 100 is defined, and the first power battery 171 and the second power battery 172 are respectively located on both sides of the longitudinal plane 103, and the first power battery 171 and the second power battery 172 are substantially symmetrical with respect to the longitudinal plane 103. This arrangement enables the power battery 17 to be arranged near the edge of the frame 11, which facilitates the removal of the first power battery 171 and the second power battery 172, and the symmetrical arrangement of the first power battery 171 and the second power battery 172 enables the center of gravity of the entire vehicle to be substantially located at the center of the electric all-terrain vehicle 100, so as to enhance the driving stability of the electric all-terrain vehicle 100.

[0025] As an optional implementation, the first power battery 171 and the second power battery 172 are both electrically connected to the drive motor 161, and the first power battery 171 and the second power battery 172 are connected in parallel, and the first power battery 171 and the second power battery 172 are both provided with separate connectors and plug connectors and are electrically connected to the drive motor 161, respectively. In this way, the first power battery 171 and the second power battery 172 can simultaneously supply power to the drive motor 161, and at the same time, the first power battery 171 and the second power battery 172 can also supply power to the drive motor 161 separately, that is, when the first power battery 171 stops supplying power or is disconnected, the second power battery 172 can still supply power normally, or when the second power battery 171 stops supplying power or is disconnected, the first power battery 172 can still supply power normally, thereby realizing the normal operation of the electric all-terrain vehicle 100.

[0026] like Figure 3As shown, the body cover 12 is at least partially connected to the first longitudinal frame 111 and the second longitudinal frame 112, so that the body cover 12 is basically arranged around the accommodating space 101, so that the body cover 12 protects the components in the accommodating space 101. The body cover 12 includes a main cover 121 and a side guard plate 122 arranged on the second longitudinal frame 1112. Specifically, the side guard plate 122 includes a left guard plate 1221 and a right guard plate 1222 distributed along the width direction of the electric all-terrain 100. The main cover 121 is fixedly connected to the second longitudinal frame 1112, and the side guard plate 122 is detachably connected to the main cover 121 and / or the frame 11. As an optional embodiment, the left side guard plate 1221 and the right side guard plate 1222 are respectively arranged near the first power battery 171 and the second power battery 172, and when viewed along the width direction of the electric all-terrain vehicle 100, the first power battery 171, the second power battery 172 and the left side guard plate 1221 and the right side guard plate 1222 at least partially overlap, that is, after the side guard plate 122 is disassembled, the battery assembly 17 can be directly contacted. Specifically, the left side guard plate 1221 and the right side guard plate 1222 are arranged so that when they are in a disassembled state, the first power battery 171 or the second power battery 172 can be directly taken out from the side without removing other components. More specifically, the side guard plate 122 can be directly clamped on the main cover 121, or the side guard plate 122 abuts against the main cover 121 and is connected to the frame 11 through fasteners such as bolts, so as to facilitate the disassembly and installation of the side guard plate 122. When the battery assembly 17 needs to be replaced, the battery assembly 17 can be quickly replaced by removing the side guard plate 122, thereby facilitating the disassembly and installation of the battery assembly 17. Optionally, when viewed from the height direction, the side guard plate 122 and the battery assembly 17 are also arranged to overlap at least partially. This arrangement makes the disassembly of the battery assembly 17 more convenient, and a reasonable disassembly method can be set according to the layout of other components. It can be understood that when the first power battery 171 is disassembled, it is only necessary to disassemble the left side guard plate 1221 arranged on one side of the first power battery 171. Similarly, the disassembly of the second power battery 172 is the same as above and will not be repeated here. Therefore, when one of the first power battery 171 or the second power battery 172 is running low on power, the left guard plate 1221 and the right guard plate 1222 can be quickly removed from the main cover 121 or the frame 11 to achieve rapid disassembly of the battery assembly 17, thereby facilitating timely replacement of the new battery assembly 17, which is beneficial to improving the assembly efficiency of the battery assembly 17, and further beneficial to improving the cruising range of the electric all-terrain vehicle 100.Furthermore, after the first power battery 171 or the second power battery 172 is removed, the storage space 101 originally used to house the first power battery 171 or the second power battery 172 can be used as a cargo box to store other items, thereby helping to improve the loading performance of the electric all-terrain vehicle 100, and further helping to improve the space utilization of the storage space 101.

[0027] It is understandable that in other embodiments, the number of the first power battery 171 and the second power battery 172 may be set to multiple to meet the needs of different vehicle models; accordingly, the first power battery 171 and the second power battery 172 may be respectively arranged on both sides of the longitudinal plane 103, or may be arranged on the same side of the longitudinal plane 103. In addition, in other embodiments, the side guard plate 122 may be set to multiple, for example, it may be set to an upper side guard plate located on the upper side of the electric all-terrain vehicle 100 or a rear side guard plate located on the rear side of the electric all-terrain vehicle 100, etc. As long as the rapid disassembly of the battery assembly 17 can be achieved, it falls within the inventive concept of the present application.

[0028] like Figure 2 As shown, the transmission assembly 15 further includes a transmission shaft 151, the drive motor 161 is transmission-connected to the transmission shaft 151, and the transmission shaft 151 is transmission-connected to the walking assembly 13, so as to realize the movement of the electric all-terrain vehicle 100. As an implementation mode, the transmission shaft 151 basically extends along the length direction of the electric all-terrain vehicle 100, the axis of the transmission shaft 151 is basically on the longitudinal plane 103, and when viewed from the width direction of the electric all-terrain vehicle 100, the first power battery 171 and the second power battery 172 are respectively located on both sides of the transmission shaft 151, and the transmission shaft 151, the first power battery 171 and the second power battery 172 are arranged to overlap at least partially. Specifically, the longitudinal plane 103 basically divides the transmission shaft 151 in half, and in order to avoid interference between the battery assembly 17 and the transmission shaft 151, a safe distance is maintained between the battery assembly 17 and the transmission shaft 151, so as to protect both the battery assembly 17 and the transmission shaft 151. In this embodiment, the drive motor 161 is transmission connected to the transmission shaft 151, the drive motor 161 is located on the rear side of the first longitudinal frame 111, the rear end of the transmission shaft 151 is transmission connected to the drive motor 161, and the front end of the transmission shaft 151 is transmission connected to the front wheel 131 through other components of the transmission assembly 15.

[0029] like Figure 4As shown, as an optional embodiment, the battery assembly 17 can be arranged close to the drive motor 161 so that the battery assembly 17 can be electrically connected to the drive motor 161. Specifically, the minimum distance H1 between the battery assembly 17 and the drive motor 161 is set to be greater than or equal to 360 mm and less than or equal to 650 mm. Further, the minimum distance H1 between the battery assembly 17 and the drive motor 161 is set to be greater than or equal to 450 mm and less than or equal to 560 mm. Furthermore, the minimum distance H1 between the battery assembly 17 and the drive motor 161 is set to 505 mm. Through the above-mentioned arrangement, it is beneficial to improve the structural compactness of the battery assembly 17 and the drive motor 161, and can effectively reduce the electrical transmission path between the battery assembly 17 and the drive motor 161, which is beneficial to improve the transmission efficiency of electrical energy in the battery assembly 17.

[0030] As an implementation method, the lowermost end of the walking assembly 13 is located on the reference plane 102, and the distance H2 between the lowermost end of the battery assembly 17 and the reference plane 102 is set to be greater than or equal to 510 mm and less than or equal to 680 mm. Specifically, the distance H2 between the lowermost end of the battery assembly 17 and the reference plane 102 is set to be greater than or equal to 580 mm and less than or equal to 650 mm. More specifically, the distance H2 between the lowermost end of the battery assembly 17 and the reference plane 102 is set to 630 mm. Through the above-mentioned settings, the electric all-terrain vehicle 100 has better passability, and at the same time, it can prevent the battery assembly 17 from being damaged by wading or colliding with the ground, which is beneficial to improve the service life of the battery assembly 17.

[0031] like Figure 2 As shown, as another implementation, the projection of the first power battery 171 assembly and the second power battery 172 assembly on the reference plane 102 along the height direction is at least partially arranged in the first projection area and at least partially located outside the second projection area. Further, the saddle assembly 14 is at least partially arranged above the second longitudinal frame 112 and is detachably connected to the second longitudinal frame 112, and the battery assembly 17 is at least partially located below the saddle assembly 14. In this embodiment, the saddle assembly 14 and the body cover 12 surround the outside of the accommodating space 101 and basically form a covering for the accommodating space 101. Optionally, when viewed from the height direction, the battery assembly 17 and the saddle assembly 14 can be arranged to basically overlap. Under this arrangement, the battery assembly 17 can also be replaced by disassembling the saddle assembly 14, which is conducive to improving the disassembly efficiency of the battery assembly 17 and the saddle assembly 14. The saddle assembly 14 has a high structural strength, so that the saddle assembly 14 can better protect the battery assembly 17, which is conducive to improving the service life of the battery assembly 17.

[0032] like Figure 5As shown, as an implementation, the vehicle body cover 12 further includes a battery box 123, which is disposed in the accommodation space 101 and fixedly connected to the first longitudinal frame 111 and the second longitudinal frame 112, respectively. The first power battery 171 assembly and the second power battery 172 are disposed in the battery box 123, and the left side guard plate 1221 and the right side guard plate 1222 are disposed close to the opening of the battery box 123, so that the battery box 123 can limit the movement of the battery assembly 17, thereby enabling the battery box 123, the left side guard plate 1221 and the right side guard plate 1222 to jointly protect the battery assembly 17. More specifically, when the opening of the battery box 123 is disposed upward, in this configuration, after the left side guard plate 1221, the right side guard plate 1222 or the saddle assembly 14 are disassembled, only the first power battery 171 or the second power battery 172 needs to be pulled out upward. When the opening of the battery box 123 is arranged away from the longitudinal plane 103, it is only necessary to remove the left side guard plate 1221 or the right side guard plate 1222 and pull out the first power battery 171 or the second power battery 172 in the corresponding direction. The above arrangement facilitates the removal of the side guard plate 122 and the battery assembly 17, thereby facilitating the removal and installation of the battery assembly 17, and further facilitating the assembly efficiency of the electric all-terrain vehicle 100. In addition, the battery box 123 can also be used as a cargo box, thereby facilitating the loading capacity of the electric all-terrain vehicle 100.

[0033] As an implementation method, the first power battery 171 and the second power battery 172 are also provided with a high-voltage wire harness 173 (see Figure 2 ), the first power battery 171 and the second power battery 172 are electrically connected to the drive motor 161 through the high-voltage wire harness 173. Specifically, the high-voltage wire harness 173 can transfer the electric energy in the first power battery 171 and the second power battery 172 to the drive motor 161. The first power battery 171 and the second power battery 172 are each provided with a high-voltage wire harness 173 connected thereto, and the high-voltage wire harnesses 173 do not interfere with each other. Through the above arrangement, the first power battery 171 and the second power battery 172 can be arranged close to the drive motor 161 to reduce the length of the high-voltage wire harness 173, thereby facilitating the improvement of the structural compactness of the high-voltage wire harness 173, the first power battery 171, the second power battery 172 and the drive motor 161, avoiding the high-voltage wire harness 173 from occupying a large vehicle body space, thereby facilitating the improvement of the space utilization rate of the electric all-terrain vehicle 100. Furthermore, the high-voltage wiring harness 173 is arranged close to the side guard plate 122 , so that the high-voltage wiring harness 173 can be removed while the side guard plate 122 is removed, which is beneficial to improving the disassembly and assembly efficiency of the battery assembly 17 .

[0034] like Figure 5As shown, in this embodiment, the first power battery 171 and the second power battery 172 are further provided with a battery output port 1711, the high-voltage wire harness 173 is connected to the battery output port 1711, the battery output port 1711 is arranged close to the opening of the battery box 123, and the side guard plate 122 is arranged to cover the opening of the battery box 123. Specifically, the high-voltage wire harness 173 is clamped with the battery output port 1711 to facilitate the removal and installation of the high-voltage wire harness 173 and the battery output port 1711. When the battery assembly 17 needs to be disassembled, the side guard plate 122 can be disassembled first, and then the high-voltage wire harness 173 is separated from the battery output port 1711, and finally the battery assembly 17 is taken out from the opening of the battery box 123, so as to realize the rapid disassembly of the battery assembly 17; when the battery assembly 17 needs to be installed, the battery assembly 17 can be put into the opening of the battery box 123 first, and then the high-voltage wire harness 173 is connected to the battery output port 1711, and finally the side guard plate 122 is installed, so as to realize the rapid installation of the battery assembly 17. Through the above arrangement, the disassembly and assembly efficiency of the battery assembly 17 can be improved, thereby improving the assembly efficiency of the electric all-terrain vehicle 100.

[0035] like Figure 5 As shown, as an implementation, a fixing structure 174 may be provided on the battery assembly 17, the fixing structure 174 is located between the side guard plate 122 and the battery assembly 17, the fixing structure 174 is clamped to the battery box 123 and covers the opening of the battery box 123, and the fixing structure 174 at least partially abuts against the battery assembly 17, so that the battery assembly 17 is fixed in the battery box 123 through the fixing structure 174. Specifically, the fixing structure 174 is used to fix the battery assembly 17, and the fixing structure 174 can limit the movement of the battery assembly 17 in the battery box 123.
