[0051] To enable those skilled in the art to better understand the present application, some embodiments of the present application are described in detail below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0052] As used herein, the term "or / and" includes any and all combinations of one or more of the related listed items.

[0053] Referring to Figures 1 and 2, this application provides an electric all-terrain vehicle 100, which includes a frame 11, a body panel 12, a running system 13, a suspension system 19, a power system 14 (see Figure 17), a cabin 15, and an electrical system 16. The body panel 12 at least partially covers the frame 11, the running system 13 is at least partially located under the frame 11 and connected to the frame 11 via the suspension system 19, and the power system 14 is supported by the frame 11 and is used to drive the running system 13. The cabin 15 is supported by the frame 11 and is used for user seating and driving.

[0054] The frame 11 includes a front frame 111 and a rear frame 112. The front frame 111 is located at the front of the vehicle, and the rear frame 112 is located at the body and rear of the vehicle. The cabin 15 is located on the rear frame 112.

[0055] The walking system 13 includes at least two front wheels 131 and at least two rear wheels 132.

[0056] The suspension system 19 includes a front suspension 191 and a rear suspension 192. The front suspension 191 connects the front wheel 131 to the front frame 111, and the rear suspension 192 connects the rear wheel 132 to the rear frame 112.

[0057] The power system 14 includes an electric motor 141 for driving the front wheel 131 and / or the rear wheel 132.

[0058] Electrical system 16 includes a low-voltage electrical system 161 and a high-voltage electrical system 162. All low-voltage devices 1611 in low-voltage electrical system 161 operate at a low voltage not exceeding 36V, and at least some high-voltage devices 1621 in high-voltage electrical system 162 operate at a high voltage above 36V. Low-voltage device 1611 includes a headlight 1611n, which is mounted on the front frame 111. High-voltage device 1621 includes a power battery 1621a (not shown), which is supported by the frame 11 and used to power motor 141. In one embodiment, power battery 1621a is supported by the front frame 111; more preferably, power battery 1621a is supported by the rear frame 112.

[0059] This application defines the front, rear, left, right, up, and down directions as shown in Figure 1. The front-rear direction refers to the front-rear direction of the electric all-terrain vehicle 100, the left-right direction refers to the left-right direction of the electric all-terrain vehicle 100, and the up-down direction refers to the up-down direction of the electric all-terrain vehicle 100. In this embodiment, the front, rear, left, right, up, and down directions are based on the state of the electric all-terrain vehicle 100 traveling on a level road surface, not on the state of traveling on an inclined road surface.

[0060] Referring to Figures 2 and 3, the front frame 111 includes a low-pressure mounting area 102 and a storage area 103. The low-pressure mounting area 102 is located above the storage area 103. The body panel 12 includes a hood 121 covering the front frame 111 and a storage cover 122 covering the front of the front frame 111. The upper side of the low-pressure mounting area 102 is covered by the hood 121, and the interior of the low-pressure mounting area 102 can be accessed by opening the hood 121. The front side of the storage area 103 is covered by the storage cover 122, and the interior of the storage area 103 can be accessed by opening the storage cover 122. When the hood 121 covers the low-pressure mounting area 102, it can be locked by an electronic lock or a physical lock. When the storage cover 122 covers the storage area 103, it can be locked by an electronic lock or a physical lock.

[0061] The low-voltage installation area 102 is mainly used to centrally house low-voltage devices 1611, facilitating centralized management and maintenance by users. It should be noted that no high-voltage devices 1621 are located in the low-voltage installation area 102. Therefore, the low-voltage devices 1611 in the low-voltage installation area 102 are less susceptible to electromagnetic interference from the high-voltage devices 1621, meaning that the operational stability of the low-voltage devices 1611 in the low-voltage installation area 102 is relatively high. The storage area 103 is mainly used to provide users with space to store their personal belongings.

[0062] The low-pressure mounting area 102 is provided with a mounting base plate 124 for defining the lower boundary of the low-pressure mounting area 102, and the mounting base plate 124 is used to separate the low-pressure mounting area 102 and the storage area 103. The mounting base plate 124 is connected to the body panel 12 and / or the front frame 111. Optionally, the mounting base plate 124 is connected to and supported by the front frame 111, and the low-pressure mounting area 102 is supported by the front frame 111 through the mounting base plate 124.

[0063] Referring to Figures 4 and 5, the low-voltage device 1611 also includes a low-voltage battery 1611a, a body controller 1611b, a fuse box 1611c, an audio amplifier 1611d, an expansion power interface 1611e, a vehicle diagnostic interface 1611f, a gateway 1611g, a winch relay 1611h, a positioning antenna 1611j, and a T-BOX 1611k. The low-voltage battery 1611a is installed in the low-voltage mounting area 102, and at least one of the other low-voltage devices 1611 besides the low-voltage battery 1611a is installed in the low-voltage mounting area 102.

[0064] In one embodiment, the body controller 1611b, T-BOX 1611k, and fuse box 1611c are located within the low-voltage mounting area 102. The body controller 1611b is located to the left or right of the low-voltage battery 1611a, the T-BOX 1611k is located behind, to the left or right of, the low-voltage battery 1611a, and the fuse box 1611c is located behind, to the left or right of, the low-voltage battery 1611a. Optionally, the body controller 1611b is located to the right of the low-voltage battery 1611a, the T-BOX 1611k is located behind the low-voltage battery 1611a, and the fuse box 1611c is located behind the low-voltage battery 1611a. The low-voltage battery 1611a is located in the middle of the low-voltage mounting area 102 in the left-right direction. The low-voltage mounting area 102 includes a front edge 1021 and a rear edge 1022. The low-voltage battery 1611a and the body controller 1611b are closer to the front edge 1021.

[0065] Specifically, the audio amplifier 1611d, the extended power interface 1611e, the vehicle diagnostic interface 1611f, the gateway 1611g, and the winch relay 1611h are all located in the low-voltage installation area 102. The low-voltage battery 1611a and the body controller 1611b are basically located in front of the audio amplifier 1611d, the vehicle diagnostic interface 1611f, the extended power interface 1611e, the fuse box 1611c, the gateway 1611g, the winch relay 1611h, and the T-BOX 1611k. That is, the low-voltage battery 1611a and the body controller 1611b are closer to the front edge 1021, in the front row; the audio amplifier 1611d, the vehicle diagnostic interface 1611f, the extended power interface 1611e, the fuse box 1611c, the gateway 1611g, the winch relay 1611h, and the T-BOX 1611k are closer to the rear edge 1022, in the rear row.

[0066] The positioning antenna 1611j can be replaced with an antenna base, such as a GNSS antenna base. The primary function of the positioning antenna 1611j is to assist the vehicle in map positioning. The body control module 1611b controls the headlights 1611n, turn signals, anti-theft locking system, and central locking. The T-BOX 1611k (Telematics Box) is a remote / vehicle communication module. The fuse box 1611c contains fuses and other components. The extended power interface 1611e can serve as a port for the vehicle to output power, such as powering a vehicle refrigerator. The vehicle diagnostic interface 1611f primarily provides a port for maintenance personnel to acquire and upload vehicle information. The winch relay 1611h mainly controls the operation of the winch mounted on the frame 11, which provides auxiliary towing and other rescue functions on the vehicle.

[0067] Each low-voltage device 1611 within the low-voltage mounting area 102 is mounted on the mounting base plate 124. In one embodiment, since the low-voltage battery 1611a is relatively tall, while the height within the low-voltage mounting area 102 is limited, a mounting hole 1243 can be opened on the mounting base plate 124. The low-voltage battery 1611a is embedded in the mounting hole 1243, meaning the bottom of the low-voltage battery 1611a is lower than the upper surface of the mounting base plate 124. Similarly, other low-voltage devices 1611 that are relatively tall can also be mounted by opening holes in the mounting base plate 124. Specifically, the mounting base plate 124 can be recessed downwards to form the mounting hole 1243, meaning the mounting hole 1243 is not connected to the storage area 103 below.

[0068] Referring to Figures 3 and 5, the mounting base plate 124 includes a front plate portion 1241 and a rear plate portion 1242. The number of front plate portions 1241 and rear plate portions 1242 can be more than one. The front edge 1021 is located on the front plate portion 1241, and the rear edge 1022 is located on the rear plate portion 1242. The upper surface of the front plate portion 1241 is substantially horizontal, while the upper surface of the rear plate portion 1242 is inclined relative to the horizontal plane, and its front edge is lower than its rear edge, thus making the upper surface of the front plate portion 1241 substantially lower than the upper surface of the rear plate portion 1242. The audio amplifier 1611d, extended power interface 1611e, fuse box 1611c, gateway 1611g, winch relay 1611h, and T-BOX 1611k are installed in the rear. Some low-voltage components 1611 are installed in the rear panel 1242, while the low-voltage battery 1611a and body controller 1611b are installed in the front panel. Some low-voltage components 1611 are installed in the front panel 1241, thus ensuring that the low-voltage components 1611 in the rear section are higher than those in the front section. Specifically, the T-BOX 1611k and audio amplifier 1611d are installed in the rear panel 1242, and the body controller 1611b is installed in the front panel 1241. In other specific embodiments, one or more low-voltage devices 1611 may be installed on the rear panel 1242, and in addition to installing the body controller 1611b, the front panel 1241 may also install a low-voltage battery 1611a, or only the low-voltage battery 1611a.

[0069] This configuration facilitates user maintenance of each low-voltage device 1611. During maintenance, the user is typically located near the front edge 1021. By raising the rear low-voltage devices 1611, the user can more easily access them. Additionally, this effectively lowers the height of the front low-voltage devices 1611, thus reducing interference from the front low-voltage devices 1611 when the user is maintaining the rear low-voltage devices 1611.

[0070] In another embodiment, the low-voltage device 1611 is not limited to the rear row and rear panel 1242. Some low-voltage devices 1611 can also be installed in the front row and front panel 1241, such as the vehicle diagnostic interface 1611f installed in the front panel 1241.

[0071] Referring to Figures 3 and 4, the body panel 12 also includes two side panels 123, located on either side of the hood 121 in the left-right direction. The side panels 123 and the hood 121 together define the upper boundary of the low-pressure mounting area 102. The side panels 123 are fixed to the mounting base plate 124 and / or the front frame 111. The side panels 123 can be fixed to the mounting base plate 124 and / or the front frame 111 by bolts or welding. When the side panels 123 are openable / closable relative to the low-pressure mounting area 102, it should be noted that the opening and closing difficulty of the hood 121 is lower than that of the side panels 123, meaning that the side panels 123 are components that are not frequently opened or closed. Viewed from top to bottom, at least a portion of at least one low-voltage device 1611 is located below the side panel 123; in other words, a portion of the low-voltage device 1611 can be accommodated below the side panel 123 and thus protected by it. In one embodiment, a portion of the audio amplifier 1611d is located below the side panel 123. In other embodiments, additional low-voltage devices 1611 may also be accommodated below the side panel 123, particularly low-voltage devices 1611 that require infrequent maintenance and need protection.

[0072] It is worth noting that the side panel 123 can not only protect the low-voltage device 1611 below it in the height direction, but also, because the two side panels 123 are located on the left and right sides of the front hood 121, the side panel 123 can also provide lateral protection for the low-voltage device 1611 in the low-voltage installation area 102.

[0073] Referring to Figure 1, optionally, the headlight 1611n has two lamps, each corresponding to a side plate 123. Viewed from above, at least a portion of the headlight 1611n is located below the corresponding side plate 123. Specifically, the headlight 1611n is positioned in a forward position on the side plate 123, and further, the front part of the headlight 1611n is located in front of the side plate 123. This arrangement achieves a reasonable component fit. Since the maintenance and disassembly frequency of the headlight 1611n is relatively low compared to other low-voltage components 1611, and the disassembly frequency of the side plate 123 is also not high, arranging the side plate 123 above the headlight 1611n not only does not affect the maintenance of the headlight 1611n, but also protects the headlight 1611n, and does not affect the daily maintenance of other low-voltage components 1611. In addition, it can form a protective barrier for other low-voltage components 1611 on both sides, ultimately achieving multiple benefits from this reasonable component fit.

[0074] Referring to Figures 4 and 5, other components requiring routine maintenance, such as the brake fluid reservoir 1244, can also be installed within the low-voltage mounting area 102. The brake fluid reservoir 1244 is located to the left of the low-voltage battery 1611a, closer to the front edge 1021. Due to the relatively high height of the brake fluid reservoir 1244, a receiving hole 1245 can be provided on the mounting base 124 to accommodate it. The receiving hole 1245 is not connected to the storage area 103 below. The brake fluid reservoir 1244 stores brake fluid for the vehicle's braking system to maintain the normal operation of the braking components during braking.

[0075] Referring to Figures 6 and 7, the opening 1031 of the storage area 103 faces forward and is located slightly below the center of the two headlights 1611n. The storage cover 122 covers the opening 1031. In one embodiment, the position originally used for the air intake grille at the front of the fuel-electric all-terrain vehicle is occupied by the storage cover 122 in the electric all-terrain vehicle 100 of this application. In other words, the storage cover 122 indirectly replaces the position of the air intake grille, and the outer surface of the storage cover 122 can form some decorative structures. Therefore, visually, the storage cover 122 as part of the storage function is less obvious, thus contributing to the aesthetics of the entire vehicle.

[0076] Referring to Figures 7 and 8, the storage area 103 is supported by the front frame 111. Specifically, the storage area 103 contains a storage container 1032. The front frame 111 includes a first longitudinal beam 1111 and a second longitudinal beam 1112. The first longitudinal beam 1111 is located above the second longitudinal beam 1112, and the storage container 1032 is at least partially located between the first longitudinal beam 1111 and the second longitudinal beam 1112. The first longitudinal beam 1111 is connected to the storage container 1032 and can provide an upward pulling force to the storage container 1032. And / or, the second longitudinal beam 1112 is connected to the storage container 1032 and can provide an upward supporting force to the storage container 1032.

[0077] Referring to Figures 8 and 9, the front frame 111 also includes a first vertical beam 1113 and a second vertical beam 1114. The first vertical beam 1113 is located in front of the second vertical beam 1114, and the storage container 1032 is at least partially located between the first vertical beam 1113 and the second vertical beam 1114. The first vertical beam 1113 and the second vertical beam 1114 can limit the storage container 1032 in the left-right direction and / or in the front-back direction.

[0078] Referring to Figure 10, in the first embodiment, there are two of each of the first vertical beam 1113 and the second vertical beam 1114. The two first vertical beams 1113 are arranged substantially horizontally, and the two second vertical beams 1114 are arranged substantially horizontally. The storage container 1032 is provided with two first slots 1032e and two second slots 1032f. The two first slots 1032e respectively engage with the two first vertical beams 1113, and the two second slots 1032f respectively engage with the two second vertical beams 1114. The storage container 1032 includes a main body 1032a, a front storage part 1032b, a rear storage part 1032c, and side storage parts 1032d. The front storage part 1032b and the rear storage part 1032c are respectively connected to the front and rear sides of the main body 1032a, and there are two side storage parts 1032d, which are respectively connected to the left and right sides of the main body 1032a. The front storage compartment 1032b is located between the two first slots 1032e and is restrained between the two first vertical beams 1113. The rear storage compartment 1032c is located between the two second slots 1032f and is restrained between the two second vertical beams 1114. The side storage compartment 1032d is restrained between the nearest first vertical beam 1113 and the nearest second vertical beam 1114.

[0079] Viewed from the left and right (see Figure 8), the front storage section 1032b at least partially overlaps with the first vertical beam 1113, and the rear storage section 1032c at least partially overlaps with the second vertical beam 1114. Viewed from the front and back (see Figure 9), the side storage section 1032d at least partially overlaps with the first vertical beam 1113, and the side storage section 1032d at least partially overlaps with the second vertical beam 1114.

[0080] Referring to Figure 11, in the second embodiment, the construction of the first vertical beam 1113 and the second vertical beam 1114 may be the same as in the first embodiment. The storage container 1032 is sandwiched between the first vertical beam 1113 and the second vertical beam 1114 in the front-to-back direction. Specifically, the storage container 1032 includes a main body 1032a and two side storage portions 1032d. The side storage portions 1032d are positioned between the nearest first vertical beam 1113 and the nearest second vertical beam 1114.

[0081] Referring to Figure 12, in the third embodiment, the construction of the first vertical beam 1113 and the second vertical beam 1114 can be the same as in the first embodiment. The storage container 1032 is sandwiched between the two first vertical beams 1113 in the left-right direction, and the storage container 1032 is also sandwiched between the two second vertical beams 1114 in the left-right direction. Specifically, the storage container 1032 includes a main body 1032a, a front storage part 1032b, and a rear storage part 1032c. The front storage part 1032b is limited between the two first vertical beams 1113, and the rear storage part 1032c is limited between the two second vertical beams 1114.

[0082] Referring to Figure 13, the front frame 111 also includes a third vertical beam 1115, which is located behind the second vertical beam 1114 and is closer to the longitudinal reference plane 101 than the second vertical beam 1114. Viewed from the left and right, the third vertical beam 1115 is located at the junction of the front frame 111 and the rear frame 112. The space between the second vertical beam 1114 and the third vertical beam 1115 can be used to accommodate components such as the vehicle's steering mechanism (not shown).

[0083] Referring to Figures 6 and 8, the body panel 12 also includes a protective plate 125. The protective plate 125 is located in front of the storage area 103. Viewed from front to back, the lower portion of the storage area 103 is covered by the protective plate 125, while the upper portion is not covered. This arrangement allows the protective plate 125 to protect the storage area 103 from the front. The protective plate 125 can be part of a high-strength body panel 12 located at the front of the vehicle, or it can be the surface covering structure of the vehicle's winch.

[0084] Referring to Figures 13 and 14, in one embodiment, the storage cover 122 is rotatable relative to the front frame 111 and has a rotation center line 1221, which is substantially parallel to the left-right direction. When the storage cover 122 is closed relative to the storage area 103, the rotation center line 1221 is located at the lower edge of the storage cover 122. Viewed in the left-right direction, the line connecting the endpoint of the storage cover 122 furthest from the rotation center line 1221 to the rotation center line 1221 is defined as the flip reference line 105. The endpoint of the storage cover 122 furthest from the rotation center line 1221 refers to the endpoint on the body of the storage cover 122 furthest from the rotation center line 1221, not the endpoint connected to a protruding part on the body of the storage cover 122. It can be understood that the endpoint of the storage cover 122 furthest from the rotation center line 1221 is on the longest side of the storage cover 122 furthest from the rotation center line 1221, which is substantially parallel to the left-right direction. A plane passing through the rotation center line 1221 and perpendicular to the front-back direction is defined as the vertical reference plane 106. When the storage cover 122 is flipped away from the storage area 103 to a position where it can no longer be flipped, the angle α between the flipping reference plane and the vertical reference plane 106 ranges from 80° to 100°. In one specific embodiment, the angle α ranges from 80° to 90°. In another specific embodiment, the angle α ranges from 90° to 100°. Specifically, the value of the angle α can be 80°, 83°, 88°, 90°, 94°, 97°, or 100°.

[0085] In one specific embodiment, when the storage cover 122 is flipped away from the storage area 103 to a position where it cannot be flipped further, the lower surface of the storage cover 122 abuts against the protective plate 125, meaning that the protective plate 125 provides upward support to the storage cover 122 at this time. With this configuration, when an item is temporarily supported on the storage cover 122, the protective plate 125 provides strong temporary support, meeting the temporary support requirements. Therefore, the protective plate 125 not only provides protection for the storage area 103 but also helps meet temporary support needs. In another specific embodiment, the front frame 111 includes a bumper 1116 located in front of the storage area 103. When the storage cover 122 is flipped away from the storage area 103 to a position where it cannot be flipped further, the lower surface of the storage cover 122 abuts against the bumper 1116, meaning that the bumper 1116 provides upward support to the storage cover 122 at this time. With this design, the bumper 1116 not only has the function of protecting against collisions, but also has the additional function of helping to meet temporary support needs.

[0086] Referring to Figures 13 and 15, in another embodiment, the storage container 1032 is movable back and forth relative to the storage area 103. The opening 1031 may be located on the upper surface of the storage container 1032 or on the front surface of the storage container 1032. When a user wants to store or retrieve items, the opening 1031 can be exposed by pulling the storage container 1032 outward. The storage cover 122 is fixed to the storage container 1032, or the storage cover 122 is rotatably connected to the front frame 111 or the body panel 12.

[0087] Referring to Figures 16 and 17, a high-voltage installation area 104 is provided within the rear frame 112. The high-voltage installation area 104 is supported by the rear frame 112 and is mainly used to centrally house high-voltage devices 1621. The rear frame 112 includes a mid-chassis 1121 and a roll cage 1125. The front end of the mid-chassis 1121 is fixed to the front frame 111, and the roll cage 1125 is fixed above the mid-chassis 1121. The cabin 15 is located within the space enclosed by the mid-chassis 1121 and the roll cage 1125. The rear frame 112 also includes a rear support frame 1122, a rear chassis 1123, and a support column 1124. The rear chassis 1123 is fixed to the rear end of the mid-chassis 1121, the rear support frame 1122 is located above the rear chassis 1123, and the support column 1124 is fixed between the rear support frame 1122 and the rear chassis 1123. The support column 1124 extends basically in the vertical direction. There are two support columns 1124, located on the left and right sides of the rear frame 112 respectively. The support column 1124 is located at the junction of the middle chassis 1121 and the rear chassis 1123. Viewed from above, the main body of the high-voltage installation area 104 is located between the rear support frame 1122 and the rear chassis 1123, and the foremost part of the high-voltage installation area 104 is located in the rear area of ​​the middle chassis 1121.

[0088] Referring to Figures 17 and 18, in one embodiment, the electric all-terrain vehicle 100 is a purely electric all-terrain vehicle, meaning that the power system 14 includes only the electric motor 141 as the drive source. In another embodiment, the electric all-terrain vehicle 100 is a hybrid all-terrain vehicle, which also includes a fuel system 142, which is a range extender and / or an engine (not shown).

[0089] This embodiment takes the pure electric all-terrain vehicle 100 as an example.

[0090] The motor 141 and the power battery 1621a are installed within the high-voltage installation area 104. The high-voltage device 1621 also includes a DC-DC converter 1621b, an on-board charger 1621c, and a power distribution unit 1621d. At least one of the other high-voltage devices 1621 besides the power battery 1621a is installed within the high-voltage installation area 104. In one embodiment, the DC-DC converter 1621b, the on-board charger 1621c, and the power distribution unit 1621d are assembled into a three-in-one controller 1621e, which is located within the high-voltage installation area 104. In other embodiments, one or two of the DC-DC converter 1621b, the on-board charger 1621c, and the power distribution unit 1621d are installed within the high-voltage installation area 104. Among them, the on-board charger 1621c can convert AC power to DC power to charge the vehicle; the DC converter 1621b mainly converts high-voltage DC power into low-voltage DC power, for example, a DC / DC converter can be selected; the power distribution unit 1621d is responsible for distributing and managing high-voltage power.

[0091] Since these high-voltage devices 1621 are concentrated in the high-voltage installation area 104, it facilitates centralized management and protection of the high-voltage devices 1621, and reduces electromagnetic interference from the high-voltage devices 1621 to the low-voltage devices 1611. Furthermore, the high-voltage devices 1621 in the vehicle are primarily related to the charging and discharging of the power battery 1621a. Therefore, installing most of the high-voltage devices 1621 and the motor 141 near the power battery 1621a not only facilitates centralized maintenance and management of high-voltage related components, but also significantly reduces the length of power supply wires between components, thereby reducing costs and enabling more convenient control of the high-voltage installation area 104, a hazardous area involving high-voltage electricity.

[0092] Referring to Figures 18 and 19, the frame 11 also includes a crossbar 113 located within the high-voltage mounting area 104. The crossbar 113 is substantially located behind the power battery 1621a and in front of the power system 14, with its two ends fixed to two support columns 1124 respectively. In one embodiment, a three-in-one controller 1621e is mounted on the crossbar 113. In another embodiment, one or two of the DC-DC converter 1621b, the on-board charger 1621c, and the power distribution unit 1621d are mounted on the crossbar 113.

[0093] The rear frame 112 also includes a seat frame 1126 located within or at the boundary of the cabin 15. The seat frame 1126 is positioned above the mid-chassis 1121, and the power battery 1621a is located between the seat frame 1126 and the mid-chassis 1121. Viewed from above, a portion of the power battery 1621a overlaps with the seat frame 1126, while the other portion is located behind the seat frame 1126. This arrangement utilizes the space below the seat frame 1126 to house the power battery 1621a, thereby improving the utilization rate of interior space. A portion of the power battery 1621a is located behind the support pillars 1124, specifically behind the line connecting the centerlines of the two support pillars 1124. This arrangement allows the two support pillars 1124 to protect the power battery 1621a in the lateral direction. The middle section of the crossbar 113 is positioned further back than the two ends in the left-right direction, meaning the middle of the crossbar 113 protrudes backward. Viewed from the left-right direction, the two ends of the crossbar 113 overlap with the power battery 1621a. This arrangement, because the crossbar 113 provides support to the rear frame 112 in the left-right direction, enhances the structural stability between the two support columns 1124, allowing the power battery 1621a to be better protected by the two support columns. Furthermore, the backward protrusion of the middle section of the crossbar 113 not only avoids the power battery 1621a but also forms an arch-like structure, providing strong resistance to impact forces from rear to front. In summary, the left, right, and rear sides of the power battery 1621a are all protected, significantly improving its safety.

[0094] The rear chassis 1123 includes a connecting section 1123a and an extension section 1123b arranged front and rear. The left and right ends of the connecting section 1123a are connected to two support columns 1124, respectively, and the front end of the extension section 1123b is fixed to the connecting section 1123a. The middle of the connecting section 1123a is positioned further back than the two ends in the left-right direction; that is, the middle of the connecting section 1123a also protrudes rearward. The shape of the connecting section 1123a is similar to that of the crossbar 113, and when viewed from above, the two at least partially overlap. In one specific embodiment, the connecting section 1123a partially overlaps with the crossbar 113, and the middle of the connecting section 1123a is positioned further back than the middle of the crossbar 113. In another specific embodiment (not shown), the connecting segment 1123a basically coincides with the crossbar 113. Therefore, the magnitude and direction of the lateral support force provided by the connecting segment 1123a and the crossbar 113 to the rear frame 112 are more similar, which helps to stabilize the structure of the rear frame 112.

[0095] The crossbar 113 includes two side segments 1131 and a middle segment 1132. The middle segment 1132 connects the two side segments 1131 and is located behind the side segments 1131. The extension direction of the middle segment 1132 is basically parallel to the left-right direction, and the extension direction of the middle segment 1132 is basically parallel to the rear side of the power battery 1621a. The high-voltage device 1621 is installed on the middle segment 1132. This arrangement allows the rear side of the power battery 1621a to be basically parallel to the middle segment 1132, thus providing a better installation environment for the high-voltage device 1621 and making it easier to electrically connect the high-voltage device 1621a to the power battery 1621a.

[0096] Referring to Figure 17, viewed from top to bottom, the three-in-one controller 1621e is basically located at the front right or front left of the power system 14, and the rear end of the three-in-one controller 1621e is located behind the front end of the power system 14. This arrangement allows the power system 14 and the three-in-one controller 1621e to be offset in the left-right direction. That is, when viewed from the left-right direction, the power system 14 and the three-in-one controller 1621e can partially overlap, and the total length of the power system 14 and the three-in-one controller 1621e in the front-back direction can be reduced, achieving efficient use of space.

[0097] Referring to Figures 19 and 20, the power battery 1621a includes a battery assembly 1621f and a battery bracket 1621g. The battery assembly 1621f is connected to the rear frame 112 via the battery bracket 1621g. Specifically, the battery assembly 1621f is mounted above the battery bracket 1621g, which is fixed to the mid-chassis 1121. A portion of the battery bracket 1621g is also fixed to the rear chassis 1123. The upper surface of the crossbar 113 is lower than the upper surface of the battery assembly 1621f. This design allows the crossbar 113 to better protect the battery assembly 1621f.

[0098] The upper surface of the high-voltage device 1621 installed on the crossbar 113 is not higher than the upper surface of the rear support frame 1122. In one embodiment, since the three-in-one controller 1621e is installed on the upper side of the crossbar 113, the upper surface of the three-in-one controller 1621e is not higher than the upper surface of the rear support frame 1122, and the rear support frame 1122 provides a certain degree of protection for the three-in-one controller 1621e.

[0099] The low-voltage device 1611 also includes a vehicle controller 1611m, which is also mounted on the crossbar 113. The three-in-one controller 1621e and the vehicle controller 1611m are arranged along the extension direction of the crossbar 113. Specifically, the three-in-one controller 1621e and the vehicle controller 1611m are both mounted in the middle section 1132.

[0100] Referring to Figures 21 and 22, a mounting bracket 1133 is fixed on the middle section 1132, and the high-voltage device 1621 is mounted on the middle section 1132 via the mounting bracket 1133. Specifically, the mounting bracket 1133 includes a first mounting bracket 1134 and a second mounting bracket 1135. The first mounting bracket 1134 is elongated and has two sections, which are welded to the middle section 1132. The three-in-one controller 1621e is fixed to the first mounting bracket 1134 with bolts. The second mounting bracket 1135 is a raised sheet metal structure and has two sections, which are fixed to the front and rear sides of the middle section 1132 respectively. Alternatively, the second mounting bracket 1135 is square tubular, with its front end fixed at the connection between the middle section 1132 and the side section 1131. The vehicle controller 1611m can be fixed to the second mounting bracket 1135 by bolts or other means.

[0101] Referring to Figure 23, the electric all-terrain vehicle 100 also includes a cargo bed 17, which is supported by a rear frame 112 and can be tilted relative to the rear frame 112. A seat 151 is located inside the cabin 15. The cargo bed 17 is located behind the seat 151 and above the power system 14. The power battery 1621a is located below the seat 151 and in front of the power system 14, with the power battery 1621a generally located below the seat 151 and the power system 14 generally located below the cargo bed 17.

[0102] Viewed from the left and right, the seat 151, cargo bed 17, power battery 1621a and power system 14 together define an installation space 107. The installation space 107 is provided with an installation component 18, which can be a container for storing tools or liquids, or it can be a tool itself.

[0103] The installation space 107 covers a wide area, with its upper portion located between the seat 151 and the cargo bed 17, and its lower portion distributed above the power battery 1621a, below the cargo bed 17, and in front of the power system 14. Therefore, the upper limit of the volume of the mounting member 18 can also be large. Specifically, the mounting member 18 is at least partially located between the seat 151 and the cargo bed 17, and at least partially located between the power battery 1621a and the cargo bed 17. Viewed from front to back, at least a portion of the seat 151, a portion of the mounting member 18, and at least a portion of the cargo bed 17 overlap, and another portion of the mounting member 18 overlaps with at least a portion of the power system 14. Viewed from top to bottom, a portion of the power battery 1621a overlaps with at least a portion of the mounting member 18, another portion of the power battery 1621a overlaps with at least a portion of the seat 151, and at least a portion of the cargo bed 17 overlaps with a portion of the mounting member 18.

[0104] In one specific embodiment, viewed from front to back (see Figure 24), a portion of the seat 151, the upper portion of the mounting member 18, and a portion of the cargo bed 17 overlap to form a first overlapping area 181. The lower portion of the mounting member 18 overlaps with the upper portion of the power system 14 to form a second overlapping area 182. Viewed from top to bottom (see Figure 25), the rear portion of the power battery 1621a overlaps with the front portion of the mounting member 18 to form a third overlapping area 183. The front portion of the power battery 1621a overlaps with the rear portion of the seat 151 to form a fourth overlapping area 184. The front portion of the cargo bed 17 overlaps with the rear portion of the mounting member 18 to form a fifth overlapping area 185.

[0105] Referring to Figures 26 to 28, the outer contour of the mounting component 18 is basically L-shaped when viewed from the left and right direction. A high-voltage device 1621 is located above and behind the power battery 1621a and above and in front of the power system 14. The mounting component 18 needs to be arranged to avoid the high-voltage device 1621. In one specific embodiment (see Figure 27), the mounting component 18 is located to one side of the high-voltage device 1621 in the left and right direction, i.e., the width of the mounting component 18 is reduced to avoid the high-voltage device 1621. In another specific embodiment (see Figure 28), the mounting component 18 occupies a larger position in the left and right direction, and a portion of the mounting component 18 can be recessed to avoid components including the high-voltage device 1621.

[0106] Referring to Figures 23 and 26, the mounting component 18 includes a housing body 185 and a connector 186. The housing body 185 is connected to the frame 11, the seat 151, or the body panel 12 via the connector 186. The housing body 185 is the main component of the mounting component 18. The connector 186 can be a plate, a square tube, or other components, and is connected to at least one of the frame 11, the seat 151, and the body panel 12 by means of bolts, snap-fits, plug-ins, welding, etc.

[0107] The distance between the frontmost and rearmost ends of the accommodating body 185 along the front-rear direction is defined as the first lateral distance L1. The ratio of the first lateral distance L1 to the wheelbase L6 of the vehicle ranges from 0.180 to 0.199. Specifically, the ratio of L1 to L6 ranges from 0.185 to 0.194. The selectable values ​​for the ratio of L1 to L6 are: 0.180, 0.185, 0.190, 0.191, 0.194, and 0.199.

[0108] The height difference between the highest and lowest points of the accommodating body 185 is defined as the first vertical spacing H1, and the ratio of the first horizontal spacing L1 to the first vertical spacing H1 ranges from 0.59 to 1.17. Specifically, the ratio of L1 to H1 ranges from 0.71 to 1.01. The selectable values ​​for the ratio of L1 to H1 are: 0.59, 0.71, 0.89, 1.01, and 1.17.

[0109] In a plane perpendicular to the vertical direction, the length of the overlapping area between the projection of the accommodating body 185 and the projection of the cargo hopper 17 is defined as the second lateral spacing L2, which is the length of the fifth overlapping area 185 along the front-back direction. The ratio of the second lateral spacing L2 to the first lateral spacing L1 ranges from 0.60 to 0.86. Specifically, the ratio of L2 to L1 ranges from 0.68 to 0.78. The selectable values ​​for the ratio of L2 to L1 are: 0.60, 0.68, 0.78, 0.83, and 0.86.

[0110] The distance between the housing 185 and the center line 1221 of the rear wheel 132 along the longitudinal direction is defined as the fourth lateral distance L4. The ratio of the fourth lateral distance L4 to the wheelbase L6 of the vehicle ranges from 0.11 to 0.17. Specifically, the ratio of L4 to L6 ranges from 0.13 to 0.15.
