[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in specific embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 An electric all-terrain vehicle 100 is shown, comprising a frame 11, a body panel 12, a running gear 13, a seat assembly 14, a transmission assembly 15, a power assembly 16, and a battery assembly 17. The frame 11 forms the basic framework of the electric all-terrain vehicle 100, supporting the body panel 12, running gear 13, seat assembly 14, transmission assembly 15, power assembly 16, and battery assembly 17. The body panel 12 is at least partially mounted on the frame 11, protecting the internal components of the electric all-terrain vehicle 100. The running gear 13 enables movement of the electric all-terrain vehicle 100. The seat assembly 14 is at least partially mounted on the frame 11, providing a place for the driver to sit. A power assembly 16 is at least partially mounted on the frame 11. The power assembly 16 drives the electric all-terrain vehicle 100. Specifically, the power assembly 16 includes a drive motor 161, which is driven via a transmission assembly 15 to at least one of the front wheel 131 and the rear wheel 132. The transmission assembly 15 is at least partially mounted on the frame 11 and is driven via a running gear 13. A battery assembly 17 is at least partially mounted on the frame 11 and provides energy to the power assembly 16. Specifically, the battery assembly 17 is electrically connected to the drive motor 161 and provides electrical energy to the drive motor 161. To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The directions shown are front, back, left, right, up, and down. In the description of this application, the length direction of the electric all-terrain vehicle 100 refers to the aforementioned front-back direction, the width direction of the electric all-terrain vehicle 100 refers to the aforementioned left-right direction, and the height direction of the electric all-terrain vehicle 100 refers to the aforementioned up-down direction.

[0023] like Figure 3As shown, the frame 11 includes a first longitudinal frame 111 and a second longitudinal frame 112 disposed above the first longitudinal frame 111. Specifically, both the first longitudinal frame 111 and the second longitudinal frame 112 are composed of a plurality of support tubes 1111 distributed along the width direction of the electric all-terrain vehicle 100. The first longitudinal frame 111 essentially constitutes the main support part of the chassis of the electric all-terrain vehicle 100, and the second longitudinal frame 112 constitutes the main support part of the beam frame of the electric all-terrain vehicle 100. The first longitudinal frame 111 and the second longitudinal frame 112 are supported by support tubes 1111 extending substantially along the height direction. Therefore, a space 101 for accommodating vehicle components is formed between the first longitudinal frame 111, which is distributed substantially along the width direction, and the second longitudinal frame 112, which is distributed substantially along the width direction, can provide support and protection for the components mounted 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 are at least partially located within the receiving space 101. Specifically, the running gear is at least partially disposed below the first longitudinal frame 111, which supports the transmission assembly 15 and the battery assembly 17, while the second longitudinal frame 112 protects them. The running gear 13 includes a front wheel 131 and a rear wheel 132, which are at least partially disposed below the first longitudinal frame 111. A drive motor 161 is driven to at least one of the front wheel 131 and the rear wheel 132 via the transmission assembly 15. The receiving space 101 is at least partially located between the front wheel 131 and the rear wheel 132, and is used to accommodate vehicle body components. It should be noted that vehicle body components refer to parts or assemblies such as the drive motor 161, the drive shaft 151, and the battery assembly 16. Understandably, 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 this application, both the first longitudinal frame 111 and the second longitudinal frame 112 are composed of two support tubes 1111 distributed along the width direction, and the two support tubes 1111 are interconnected by several hollow tubes or solid pieces extending along 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 whole vehicle and maximizing the installation space. The body panel 12 is at least partially connected to the first longitudinal frame 111 and the second longitudinal frame 112, so that the body panel 12 is arranged substantially around the receiving space 101.

[0024] like Figure 2As shown, in one implementation, the battery assembly 17 includes a first power battery 171 and a second power battery 172. Both the first power battery 171 and the second power battery 172 are at least partially located within the receiving space 101, and both are mounted on the first longitudinal frame 111. A reference plane 102 perpendicular to the height direction of the electric all-terrain vehicle 100 is defined. The area occupied by the projection of the first longitudinal frame 111 along the height direction onto the reference plane 102 is defined as the first projection area, and the area occupied by the projection of the second longitudinal frame 112 along the height direction onto the reference plane 102 is defined as the second projection area. Viewed from the height direction, both the first power battery 171 and the second power battery 172 are located within the first projection area, and both 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 is defined, perpendicular to the width direction of the electric all-terrain vehicle 100 and passing through the center of the width of the electric all-terrain vehicle 100. The first power battery 171 and the second power battery 172 are 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 allows the power battery 17 to be placed near the edge of the frame 11, facilitating the removal of the first power battery 171 and the second power battery 172. Furthermore, the symmetrical arrangement of the first power battery 171 and the second power battery 172 ensures that the center of gravity of the entire vehicle is substantially located at the center of the electric all-terrain vehicle 100, thereby enhancing the driving stability of the electric all-terrain vehicle 100.

[0025] As one possible implementation, both the first power battery 171 and the second power battery 172 are electrically connected to the drive motor 161. The first power battery 171 and the second power battery 172 are connected in parallel, and each of the first power battery 171 and the second power battery 172 has its own connector and plug, which are electrically connected to the drive motor 161 respectively. This allows the first power battery 171 and the second power battery 172 to supply power to the drive motor 161 simultaneously, or the first power battery 171 and the second power battery 172 to supply power to the drive motor 161 independently. 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 panel 12 is at least partially connected to the first longitudinal frame 111 and the second longitudinal frame 112, such that the body panel 12 is arranged substantially around the receiving space 101 to protect the components within the receiving space 101. The body panel 12 includes a main panel 121 and side panels 122 disposed on the second longitudinal frame 1112. Specifically, the side panels 122 include a left side panel 1221 and a right side panel 1222 distributed along the width direction of the electric all-terrain vehicle 100. The main panel 121 is fixedly connected to the second longitudinal frame 1112, and the side panels 122 are detachably connected to the main panel 121 and / or the frame 11. As an alternative implementation, the left side guard plate 1221 and the right side guard plate 1222 are respectively positioned close to the first power battery 171 and the second power battery 172. Viewed along the width of the electric all-terrain vehicle 100, the first power battery 171, the second power battery 172, and the left and right side guard plates 1221 and 1222 at least partially overlap, meaning that after the side guard plate 122 is disassembled, it can directly contact the battery assembly 17. Specifically, the left side guard plate 1221 and the right side guard plate 1222 are configured such that when they are in the disassembled state, the first power battery 171 or the second power battery 172 can be directly removed from the side without removing other components. More specifically, the side guard plate 122 can be directly snapped onto the main cover 121, or the side guard plate 122 can abut against the main cover 121 and be connected to the frame 11 by bolts or other fasteners, facilitating the disassembly and installation of the side guard plate 122. When the battery assembly 17 needs to be replaced, it can be quickly replaced simply by removing the side guard plate 122, thus 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 designed 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. Understandably, when disassembling the first power battery 171, only the left side guard plate 1221 located on one side of the first power battery 171 needs to be removed. Similarly, the disassembly of the second power battery 172 is the same as above, and will not be described again here. Therefore, when one of the first power battery 171 or the second power battery 172 is low on power, the left side guard plate 1221 and the right side guard plate 1222 can be quickly removed from the main cover 121 or the frame 11 to achieve quick removal of the battery pack 17, thereby facilitating timely replacement of the new battery pack 17, which helps to improve the assembly efficiency of the battery pack 17, and thus helps to improve the driving 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 improving the loading performance of the electric all-terrain vehicle 100 and further improving the space utilization rate of the storage space 101.

[0027] It is understood that in other embodiments, the number of the first power battery 171 and the second power battery 172 can also be set to multiple to meet the needs of different vehicle models; correspondingly, the first power battery 171 and the second power battery 172 can be respectively arranged on both sides of the longitudinal plane 103, or they can be arranged on the same side of the longitudinal plane 103. In addition, in other embodiments, the side guard plate 122 can also be set to multiple, for example, it can be set as 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 it can realize the quick disassembly of the battery assembly 17, it falls within the inventive concept of this application.

[0028] like Figure 2 As shown, the transmission assembly 15 also includes a transmission shaft 151, with a drive motor 161 drivingly connected to the transmission shaft 151. The transmission shaft 151 is then drivingly connected to the walking assembly 13, thereby enabling the movement of the electric all-terrain vehicle 100. In one implementation, the transmission shaft 151 extends substantially along the length of the electric all-terrain vehicle 100, with its axis substantially on the longitudinal plane 103. Viewed from the width direction of the electric all-terrain vehicle 100, the first power battery 171 and the second power battery 172 are located on opposite sides of the transmission shaft 151, and the transmission shaft 151, the first power battery 171, and the second power battery 172 are configured to at least partially overlap. Specifically, the longitudinal plane 103 substantially bisects the transmission shaft 151. 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, thus protecting both the battery assembly 17 and the transmission shaft 151. In this embodiment, the drive motor 161 is connected to the drive shaft 151. The drive motor 161 is located at the rear of the first longitudinal frame 111. The rear end of the drive shaft 151 is connected to the drive motor 161, and the front end of the drive shaft 151 is connected to the front wheel 131 through other components of the transmission assembly 15.

[0029] like Figure 4As shown, as an alternative implementation, the battery assembly 17 can be positioned close to the drive motor 161 to facilitate electrical connection between the battery assembly 17 and 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. Even further, the minimum distance H1 between the battery assembly 17 and the drive motor 161 is set to 505 mm. These settings improve the structural compactness of the battery assembly 17 and the drive motor 161, effectively reduce the electrical transmission path between them, and improve the energy transfer efficiency within the battery assembly 17.

[0030] In one implementation, the lowest point of the walking component 13 is located on the reference plane 102, and the distance H2 between the lowest point of the battery component 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 lowest point of the battery component 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 lowest point of the battery component 17 and the reference plane 102 is set to 630 mm. Through these settings, the electric all-terrain vehicle 100 has good passability, while also preventing the battery component 17 from being damaged by wading through water or colliding with the ground, thereby improving the service life of the battery component 17.

[0031] like Figure 2 As shown, in another implementation, the projections of the first power battery 171 assembly and the second power battery 172 assembly along the height direction onto the reference plane 102 are at least partially located within the first projection area and at least partially located outside the second projection area. Further, the saddle assembly 14 is at least partially located above and 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 panel 12 surround the outside of the receiving space 101 and substantially cover the receiving space 101. Optionally, viewed from the height direction, the battery assembly 17 and the saddle assembly 14 can be configured to substantially overlap. In this configuration, the battery assembly 17 can be replaced by disassembling the saddle assembly 14, thereby improving the disassembly efficiency of the battery assembly 17 and the saddle assembly 14. The saddle assembly 14 has high structural strength, allowing it to better protect the battery assembly 17, thus improving the service life of the battery assembly 17.

[0032] like Figure 5As shown, in one implementation, the vehicle body panel 12 also includes a battery box 123. The battery box 123 is disposed within the accommodating space 101 and is 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 within the battery box 123. The left side guard plate 1221 and the right side guard plate 1222 are positioned near the opening of the battery box 123 so that the battery box 123 can restrict 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 facing upwards, in this configuration, after disassembling the left side guard plate 1221, the right side guard plate 1222, or the saddle assembly 14, it is only necessary to pull out the first power battery 171 or the second power battery 172 upwards. When the opening of the battery box 123 is positioned away from the longitudinal plane 103, only the left side guard plate 1221 or the right side guard plate 1222 needs to be removed, and the first power battery 171 or the second power battery 172 can be pulled out in the corresponding direction. This arrangement facilitates the removal of the side guard plates 122 and the battery assembly 17, thereby improving the disassembly and installation of the battery assembly 17 and consequently increasing the assembly efficiency of the electric all-terrain vehicle 100. Furthermore, the battery box 123 can also be used as a cargo box, thus increasing the loading capacity of the electric all-terrain vehicle 100.

[0033] As one implementation method, a high-voltage wiring harness 173 is also provided on the first power battery 171 and the second power battery 172 (see... Figure 2 The first power battery 171 and the second power battery 172 are electrically connected to the drive motor 161 via a high-voltage wiring harness 173. Specifically, the high-voltage wiring harness 173 can transfer electrical energy from the first power battery 171 and the second power battery 172 to the drive motor 161. Each of the first power battery 171 and the second power battery 172 is provided with a high-voltage wiring harness 173 connected to it, and the high-voltage wiring 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 placed close to the drive motor 161 to reduce the length of the high-voltage wiring harness 173, thereby improving the structural compactness of the high-voltage wiring harness 173, the first power battery 171, the second power battery 172 and the drive motor 161, avoiding the high-voltage wiring harness 173 occupying a large amount of vehicle body space, and thus improving the space utilization rate of the electric all-terrain vehicle 100. Furthermore, the high-voltage wiring harness 173 is positioned close to the side guard plate 122, which allows for the removal of the high-voltage wiring harness 173 while removing the side guard plate 122, thereby improving the efficiency of battery assembly 17 removal and installation.

[0034] like Figure 5As shown, in this embodiment, the first power battery 171 and the second power battery 172 are also provided with battery output ports 1711. A high-voltage wiring harness 173 is connected to the battery output port 1711. The battery output port 1711 is located near the opening of the battery box 123, and the side panel 122 is configured to cover the opening of the battery box 123. Specifically, the high-voltage wiring harness 173 is snapped into the battery output port 1711 to facilitate the disassembly and installation of the high-voltage wiring harness 173 and the battery output port 1711. When the battery assembly 17 needs to be disassembled, the side guard plate 122 can be removed first, then the high-voltage wiring harness 173 can be separated from the battery output port 1711, and finally the battery assembly 17 can be taken out from the opening of the battery box 123, thus achieving quick disassembly of the battery assembly 17. When the battery assembly 17 needs to be installed, the battery assembly 17 can be inserted into the opening of the battery box 123 first, then the high-voltage wiring harness 173 can be connected to the battery output port 1711, and finally the side guard plate 122 can be installed, thus achieving quick installation of the battery assembly 17. Through the above settings, 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, in one implementation, a fixing structure 174 can 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 snapped onto the battery box 123 and covers the opening of the battery box 123. The fixing structure 174 at least partially abuts against the battery assembly 17, so that the battery assembly 17 is fixed inside the battery box 123 by the fixing structure 174. Specifically, the fixing structure 174 is used to fix the battery assembly 17 and can restrict the movement of the battery assembly 17 within the battery box 123. More specifically, when the electric all-terrain vehicle 100 is in motion, the fixing structure 174 can prevent the battery assembly 17 from moving towards the opening of the battery box 123. Through the above arrangement, the connection between the battery box 123, the battery assembly 17, and the fixing structure 174 can be made stable, thereby improving the connection stability of the battery box 123, the battery assembly 17, and the fixing structure 174, and thus improving the structural stability of the electric all-terrain vehicle 100. Furthermore, the fixing structure 174 can be adjusted according to the position of the opening of the battery box 123. When the opening of the battery box 123 faces upward, the fixing structure 174 is located on the upper side of the battery assembly 17; when the opening of the battery box 123 faces left, the fixing structure 174 is located on the left side of the battery assembly 17; and when the opening of the battery box 123 faces right, the fixing structure 174 is located on the right side of the battery assembly 17. This arrangement improves the protective performance of the battery assembly 17, thereby enhancing the safety performance of the electric all-terrain vehicle 100.

[0036] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
