[0030] 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.

[0031] like Figures 1 to 4 An all-terrain vehicle 100 is shown, and the all-terrain vehicle 100 includes a frame 11, a body cover 12, a travel assembly 13, a power assembly 14, a power battery 15, a transmission assembly 16, a seat assembly 17 and a cargo box assembly 18. The frame 11 is used as the basic framework of the all-terrain vehicle 100 to carry the body cover 12, the travel assembly 13, the power assembly 14, the power battery 15, the transmission assembly 16, the seat assembly 17 and the cargo box assembly 18. The body cover 12 is at least partially arranged on the frame 11, and the body cover 12 and the frame 11 are connected to form a protective frame for protecting the internal parts of the all-terrain vehicle 100. The travel assembly 13 is at least partially arranged under the frame 11, and the travel assembly 13 includes a front wheel 131 and a rear wheel 132. The power assembly 14 is supported by the frame 11, and the power assembly 14 is connected to at least one of the front wheel 131 and the rear wheel 132 through the transmission assembly 16, so that the power assembly 14 can drive the all-terrain vehicle 100 to move. The power battery 15 is at least partially disposed on the frame 11, and the power battery 15 can also provide energy for the power assembly 14. The seat assembly 17 is at least partially disposed on the frame 11, and is used to provide support for the driver and the passenger. The cargo box assembly 18 is at least partially disposed on the rear side of the frame 11, and the cargo box assembly 18 is used to carry cargo on the all-terrain vehicle 100. Specifically, the frame 11 includes a rear frame 111 disposed at the rear of the frame 11, and the rear frame 111 is surrounded by a receiving space 1111, and the power assembly 14 is at least partially disposed in the receiving space 1111. In order to clearly illustrate the technical solution of the present invention, the following is also defined. Figure 1 In the present application, the front-to-back direction of the all-terrain vehicle 100 refers to the length direction of the all-terrain vehicle 100, the left-to-right direction of the all-terrain vehicle 100 refers to the width direction of the all-terrain vehicle 100, and the up-down direction of the all-terrain vehicle 100 refers to the height direction of the all-terrain vehicle 100.

[0032] As an implementation method, the power assembly 14 includes a drive motor 141 and a range extender 142, and the drive motor 141 and the range extender 142 are at least partially disposed in the accommodation space 1111. The range extender 142 provides energy for the drive motor 141, and the drive motor 141 is used to drive at least one of the front wheel 131 and the rear wheel 132. Among them, the power battery 15 is electrically connected to the range extender 142, so that the range extender 142 can charge the power battery 15; the power battery 15 is also electrically connected to the drive motor 141, so that the power battery 15 provides energy for the drive motor 141.

[0033] like Figure 3 As shown, a reference plane 101 perpendicular to the height direction of the all-terrain vehicle 100 is defined, the projection of the rear frame 111 along the height direction of the all-terrain vehicle 100 on the reference plane 101 is a first projection plane, the projection of the range extender 142 and the drive motor 141 along the height direction of the all-terrain vehicle 100 in the first projection plane is a second projection plane, and the ratio of the area of ​​the second projection plane to the area of ​​the first projection plane is greater than or equal to 0.26 and less than or equal to 0.49. Among them, the first projection surface is the projection of the accommodation space 1111 formed around the rear frame 111 on the reference plane 101 along the height direction of the all-terrain vehicle 100; the range extender 142 and the drive motor 141 both have an outer shell, and the second projection surface is the total projection of the outer shell of the range extender 142 and the outer shell of the drive motor 141 on the reference plane 101 along the height direction of the all-terrain vehicle 100, that is, the second projection surface does not include the projection of the structure such as the wiring harness on the range extender 142 and the drive motor 141, and only includes the projection of the body of the range extender 142 and the drive motor 141. Specifically, the ratio of the area of ​​the second projection surface to the area of ​​the first projection surface is greater than or equal to 0.3 and less than or equal to 0.42. More specifically, the ratio of the area of ​​the second projection surface to the area of ​​the first projection surface can also be 0.37. Through the above arrangement, it is possible to prevent the second projection surface from being too small and thus being unfavorable for the arrangement of the range extender 142 and the drive motor 141, and to prevent the second projection surface from being too large and occupying too much arrangement space of the frame 11. Thus, while meeting the arrangement requirements of the range extender 142 and the drive motor 141, it is beneficial to arrange other components of the all-terrain vehicle 100, and prevent interference between the power assembly 14 and other components of the all-terrain vehicle 100, thereby improving the space utilization and structural compactness of the all-terrain vehicle 100.

[0034] In this embodiment, when viewed from the width direction of the all-terrain vehicle 100, the drive motor 141 and the range extender 142 at least partially overlap. When viewed from the length direction of the all-terrain vehicle 100, the drive motor 141 and the range extender 142 at least partially overlap. Through the above arrangement, the space occupancy rate of the drive motor 141 and the range extender 142 can be reduced without affecting the normal operation of the drive motor 141 and the range extender 142, so that the structure of the drive motor 141 and the range extender 142 is more compact, thereby improving the space utilization rate and structural compactness of the all-terrain vehicle 100. Specifically, the drive motor 141 is at least partially arranged on the rear side of the range extender 142.

[0035] As an implementation, the drive motor 141 and the range extender 142 are distributed along the width direction of the all-terrain vehicle 100. Specifically, along the width direction of the all-terrain vehicle 100, the drive motor 141 is at least partially disposed on a first side of the all-terrain vehicle 100, and the range extender 142 is at least partially disposed on a second side of the all-terrain vehicle 100 away from the first side. The first side may be the left side or the right side of the all-terrain vehicle 100, and the second side may be the right side or the left side of the all-terrain vehicle 100, as long as the first side and the second side are different sides of the all-terrain vehicle 100. In this embodiment, a longitudinal plane 102 perpendicular to the width direction of the all-terrain vehicle 100 is defined, and the all-terrain vehicle 100 is basically symmetrically arranged about the longitudinal plane 102. The center of gravity of the drive motor 141 and the center of gravity of the range extender 142 are respectively arranged on both sides of the longitudinal plane 102, so that the load of the drive motor 141 and the range extender 142 on the all-terrain vehicle 100 is more uniform, that is, the drive motor 141 and the range extender 142 distributed along the width direction of the all-terrain vehicle 100 can be arranged so that the center of gravity of the all-terrain vehicle 100 is closer to the longitudinal plane 102, thereby improving the driving stability of the all-terrain vehicle 100.

[0036] As an implementation, the all-terrain vehicle 100 further includes an air intake assembly 19 and an exhaust assembly 21, wherein the air intake assembly 19 is connected to the air intake passage of the range extender 142, and the exhaust assembly 21 is connected to the exhaust passage of the range extender 142, wherein the air intake assembly 19 is used to deliver outside air to the range extender 142, and the exhaust assembly 21 is used to discharge the exhaust gas generated by the operation of the range extender 142. The range extender 142 includes a crankshaft mechanism 1421, which basically extends along the length direction of the all-terrain vehicle 100, and along the width direction of the all-terrain vehicle 100, the air intake assembly 19 and the exhaust assembly 21 are respectively arranged on both sides of the crankshaft mechanism 1421. Specifically, the exhaust assembly 21 is at least partially arranged on a side of the range extender 142 away from the drive motor 141, and the air intake assembly 19 is at least partially arranged on a side of the range extender 142 close to the drive motor 141, that is, the exhaust assembly 21 is arranged close to the outer side of the all-terrain vehicle 100, and the air intake assembly 19 is arranged close to the inner side of the all-terrain vehicle 100. Through the above arrangement, the length of the exhaust assembly 21 can be shortened while meeting the performance requirements of the range extender 142, which is beneficial to improving the structural compactness of the exhaust assembly 21; at the same time, it can avoid that the distance between the exhaust assembly 21 and the drive motor 141 is too small to affect the normal operation of the drive motor 141, and improve the working stability of the all-terrain vehicle 100. In this embodiment, the exhaust assembly 21 includes an exhaust pipe 211 connected to the range extender 142, and the length L1 of the exhaust pipe 211 along the exhaust direction is set to be greater than or equal to 800mm and less than or equal to 1300mm. Specifically, the length L1 of the exhaust pipe 211 along the exhaust direction can also be set to 1031mm. Among them, the exhaust direction is the moving direction of the exhaust gas generated by the range extender 142 in the exhaust pipe 211. Through the above arrangement, the length of the exhaust assembly 21 can be shortened while meeting the performance requirements of the range extender 142, which is beneficial to improving the structural compactness of the exhaust assembly 21.

[0037] like Figure 4As shown, as an implementation, the frame 11 further includes a middle frame 112 disposed between the front wheel 131 and the rear wheel 132, the middle frame 112 is surrounded by a receiving space 1121, the power battery 15 is at least partially disposed in the receiving space 1121, and the power battery 15 is also at least partially disposed on the lower side of the seat assembly 17. The seat assembly 17 includes at least one row of seats, and the length of the power battery 15 along the length direction of the all-terrain vehicle 100 is greater than the length of one row of the seats along the length direction of the all-terrain vehicle 100. Further, a reference plane 101 perpendicular to the height direction of the all-terrain vehicle 100 is defined, the projection of the power battery 15 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is a first projection plane, the projection of the seat assembly 17 on the first projection plane along the height direction of the all-terrain vehicle 100 is a second projection plane, and the ratio of the area of ​​the second projection plane to the area of ​​the first projection plane is greater than or equal to 0.34 and less than or equal to 0.65. Among them, the second projection surface refers to the total projection of the seat cushions of all seats of the seat assembly 17 on the first projection surface along the height direction of the all-terrain vehicle 100. Specifically, the ratio of the area of ​​the second projection surface to the area of ​​the first projection surface is greater than or equal to 0.41 and less than or equal to 0.57. More specifically, the ratio of the area of ​​the second projection surface to the area of ​​the first projection surface can also be 0.49. Through the above arrangement, the volume of the power battery 15 can be increased to increase the capacity of the power battery 15 while meeting the layout requirements of the front and rear parts of the seat assembly 17, thereby improving the endurance of the all-terrain vehicle 100, and at the same time, the space utilization rate of the power battery 15 to the all-terrain vehicle 100 is also improved, so that the structure of the all-terrain vehicle 100 is more compact. In addition, through the above arrangement, the relative position of the power assembly 15 and the seat assembly 17 can be prevented from affecting the riding experience of the driver and / or passengers, thereby improving the human-computer interaction and comfort of the all-terrain vehicle 100.

[0038] In this embodiment, the seat assembly 17 includes a front row seat 171 and a rear row seat 172 arranged at the rear side of the front row seat 171. The front row seat 171 includes a front row seat cushion 1711, and the projection of the front row seat cushion 1711 on the first projection plane along the height direction of the all-terrain vehicle 100 is a third projection plane. The rear row seat 172 includes a seat cushion 1722, and the projection of the seat cushion 1722 on the first projection plane along the height direction of the all-terrain vehicle 100 is a fourth projection plane. Among them, the ratio of the area of ​​the third projection plane to the area of ​​the first projection plane is greater than or equal to 0.24 and less than or equal to 0.47, and the ratio of the area of ​​the fourth projection plane to the area of ​​the first projection plane is greater than or equal to 0.1 and less than or equal to 0.18. Specifically, the ratio of the area of ​​the third projection plane to the area of ​​the first projection plane is greater than or equal to 0.3 and less than or equal to 0.42, and the ratio of the area of ​​the fourth projection plane to the area of ​​the first projection plane is greater than or equal to 0.12 and less than or equal to 0.16. More specifically, the ratio of the area of ​​the third projection surface to the area of ​​the first projection surface can also be 0.36, and the ratio of the area of ​​the fourth projection surface to the area of ​​the first projection surface can also be 0.14. Through the above arrangement, it is possible to prevent the power battery 15 from affecting the arrangement of components such as the brake and accelerator in front of the front seat 171, and it is also possible to prevent the power battery 15 from affecting the arrangement of components such as the power assembly 14 in the rear side of the rear seat 172, so as to increase the volume of the power battery 15 while meeting the arrangement requirements of components such as the power assembly 14, thereby improving the endurance and structural compactness of the all-terrain vehicle 100.

[0039] As an implementation method, the length of the power battery 15 along the length direction of the all-terrain vehicle 100 is set to the battery length L2, the projection of the axis of the front wheel 131 along the height direction of the all-terrain vehicle 100 on the reference plane 101 is the first projection line, the projection of the axis of the rear wheel 132 along the height direction of the all-terrain vehicle 100 on the reference plane 101 is the second projection line, the distance between the first projection line and the second projection line in the length direction of the all-terrain vehicle 100 is set to the axle distance L3, and the ratio of the battery length L2 to the axle distance L3 is greater than or equal to 0.17 and less than or equal to 0.34. Specifically, the ratio of the battery length L2 to the axle distance L3 is greater than or equal to 0.21 and less than or equal to 0.3. More specifically, the ratio of the battery length L2 to the axle distance L3 can also be 0.26.

[0040] In this embodiment, the projection of the power battery 15 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is the first projection plane, the distance between the front end of the first projection plane and the first projection line along the length direction of the all-terrain vehicle 100 is set to a first distance L4, the distance between the rear end of the first projection plane and the second projection line along the length direction of the all-terrain vehicle 100 is set to a second distance L5, and the ratio of the first distance L4 to the second distance L5 is greater than or equal to 0.61 and less than or equal to 1.14. Specifically, the ratio of the first distance L4 to the second distance L5 is greater than or equal to 0.74 and less than or equal to 1. More specifically, the ratio of the first distance L4 to the second distance L5 may be greater than or equal to 0.88.

[0041] If the battery length L2 is too small, the capacity of the power battery 15 will be affected, thereby reducing the endurance of the ATV 100; if the battery length L2 is too large, or the ratio of the first distance L4 to the second distance L5 is too large or too small, it will interfere with the front wheel 131 and the components on the front side of the ATV 100, and / or interfere with the rear wheel 132 and the components on the rear side of the ATV 100. Therefore, through the above arrangement, the compactness of the structure of the ATV 100 can be improved while meeting the endurance requirements of the ATV 100 and the layout requirements of the power battery 15 and other components of the ATV 100, and the driving stability of the ATV 100 can be improved.

[0042] like Figure 4 , Figure 5 and Figure 6 As shown, as an implementation, the body cover 12 includes a guard plate structure 121, which is disposed on the lower side of the power battery 15 to protect the power battery 15. The guard plate structure 121 is connected to the mid-frame 112 to form a heat dissipation space 1211, and the power battery 15 is at least partially disposed in the heat dissipation space 1211. The heat dissipation space 1211 is also connected to the outside, so that during the driving process of the all-terrain vehicle 100, air can be transported from the outside to the heat dissipation space 1211, thereby cooling the power battery 15 located in the heat dissipation space 1211, thereby improving the heat dissipation effect of the power battery 15, which is conducive to improving the stable operation of the power battery 15.

[0043] In this embodiment, a plurality of connection points 1122 are provided on the lower side of the mid-frame 112, and the power battery 15 is fixedly connected to the mid-frame 112 through the connection points 1122, so that the power battery 15 can be installed on the mid-frame 112 from the lower side of the all-terrain vehicle 100, thereby facilitating the disassembly and assembly of the power battery 15 without disassembling other components. In addition, a positioning point 1123 is also provided on the lower side of the mid-frame 112, and the positioning point 1123 is used to limit the relative position between the mid-frame 112 and the power battery 15, so that after the mid-frame 112 and the power battery 15 are positioned through the positioning point 1123, the power battery 15 is fixedly connected to the mid-frame 112 through the connection point 1122, thereby improving the installation accuracy of the power battery 15 and the mid-frame 112. The positioning point 1123 can be set as a first positioning hole, and the power battery 15 can be provided with a second positioning hole that matches the first positioning hole. The first positioning hole and the second positioning hole can be connected by a positioning pin to achieve the positioning of the power battery 15 and the mid-mounted frame 112.

[0044] As an implementation method, the lowermost end of the power battery 15 is arranged at the lower side of the lowermost end of the mid-mounted frame 112, so that the lowermost end of the power battery 15 is located at the lower side of the frame 11, so as to lower the center of gravity of the all-terrain vehicle 100, thereby improving the driving stability and controllability of the all-terrain vehicle 100. In this embodiment, the lowermost ends of the front wheel 131 and the rear wheel 132 are basically located on the reference plane 101, and the minimum distance H1 between the power battery 15 and the reference plane 101 is set to be greater than or equal to 220 mm and less than or equal to 420 mm. Among them, the minimum distance H1 in this application refers to the ground clearance of the power battery 15. Specifically, the minimum distance H1 between the power battery 15 and the reference plane 101 is set to be greater than or equal to 270 mm and less than or equal to 370 mm. More specifically, the minimum distance H1 between the power battery 15 and the reference plane 101 is set to 320 mm. Through the above-mentioned configuration, it is possible to avoid the ground clearance of the power battery 15 being too high, which is not conducive to lowering the center of gravity of the all-terrain vehicle 100, thereby improving the driving stability and controllability of the all-terrain vehicle 100 by lowering the center of gravity of the all-terrain vehicle 100; it is also possible to avoid the ground clearance of the power battery 15 being too low, which reduces the passability of the all-terrain vehicle 100, thereby meeting the driving needs of the all-terrain vehicle 100 on complex terrain.

[0045] As an implementation, the transmission assembly 16 includes a transmission shaft 162 and a reducer 161, wherein the reducer 161 is disposed on the drive motor 141 and is in transmission connection with the drive motor 141, and the reducer 161 is also rotationally connected to the transmission shaft 162, and the transmission shaft 162 is also in transmission connection with at least one of the front wheel 131 and the rear wheel 132, so that the drive motor 141 can be in transmission connection with at least one of the front wheel 131 and the rear wheel 132, thereby realizing the movement of the all-terrain vehicle 100. Among them, the reducer 161 is also at least partially disposed between the drive motor 141 and the range extender 142, so that the compactness of the structure of the power assembly 14 and the transmission assembly 16 can be improved.

[0046] Specifically, a evasion portion 1511a is formed on the upper side of the power battery 15, and the evasion portion 1511a is used to evade the transmission shaft 162, and the evasion portion 1511a extends substantially along the extension direction of the transmission shaft 162. The transmission shaft 162 substantially extends along the length direction of the all-terrain vehicle 100. Through the above arrangement, the power battery 15 can be arranged on the lower side of the transmission shaft 162 without interfering with the transmission shaft 162, thereby facilitating the normal operation of the power battery 15 and the transmission shaft 162, and improving the working stability of the power battery 15 and the transmission shaft 162. In addition, the arrangement of the evasion portion 1511a can also reduce the distance between the power battery 15 and the transmission shaft 162, thereby making the structure of the power battery 15 and the transmission shaft 162 more compact, thereby improving the structural compactness of the all-terrain vehicle 100.

[0047] In this embodiment, the power battery 15 has an upper surface 1511b that is substantially perpendicular to the height direction of the all-terrain vehicle 100. The upper surface 1511b is recessed and has an avoidance portion 1511a. The acute angle α formed by the upper surface 1511b and the axis of the transmission shaft 162 is set to be greater than or equal to 1° and less than or equal to 5°. Specifically, the acute angle α can be set to be greater than or equal to 2° and less than or equal to 3.5°. More specifically, the acute angle α can also be set to 2.5°. Through the above-mentioned setting, it is possible to prevent the acute angle α from being set too small and affecting the passability of the all-terrain vehicle 100, and it is also possible to prevent the acute angle α from being set too large, causing the height of the seat assembly 17 to be too high and reducing the comfort of the user, thereby improving the comfort of the all-terrain vehicle 100. In addition, the two ends of the transmission shaft 162 are also connected to the front axle and the rear axle, and the height positions of the front axle and the rear axle on the all-terrain vehicle 100 are basically the same. Through the above setting, it is also possible to prevent the acute angle α from being set too large, which may cause the connection between the transmission shaft 162 and the front axle, and the transmission shaft 162 and the rear axle to break, thereby improving the service life and working stability of the transmission assembly 16, and further improving the safety of the all-terrain vehicle 100.

[0048] As an implementation method, the power battery 15 includes a battery housing 151 and a battery module 152 disposed in the battery housing 151. Through the above arrangement, the battery modules 152 that meet the assembly conditions of the battery housing 151 can be disposed in the battery housing 151 to provide energy for the all-terrain vehicle 100, thereby improving the versatility of the battery housing 151 and realizing the modularization of the power battery 15. Specifically, along the width direction of the all-terrain vehicle 100, the battery modules 152 are distributed on both sides of the avoidance portion 1511a, so that the load distribution of the power battery 15 on both sides of the avoidance portion 1511a can be more uniform, improving the balance of the all-terrain vehicle 100, and further improving the driving stability of the all-terrain vehicle 100. In addition, the battery housing 151 can also protect the battery module 152, avoiding the battery module 152 from being damaged and causing safety hazards, thereby improving the safety of the all-terrain vehicle 100.

[0049] In this embodiment, the battery housing 151 includes a detachably connected upper cover 1511 and a bottom housing 1512, which can facilitate the disassembly and assembly of the battery module 152, so that the power battery 15 can select different battery modules 152 according to the specific vehicle type, so as to improve the versatility and modularity of the power battery 15. Specifically, the avoidance portion 1511a is provided on the upper cover 1511, and only the upper cover 1511 of the battery housing 151 needs to be processed, so that the processing difficulty of the battery housing 151 can be reduced, the processing efficiency can be improved, and the avoidance portion 1511a is prevented from interfering with the battery module 152, which is conducive to the normal operation of the battery module 152.

[0050] As an implementation method, the power battery 15 further includes a battery management module 153, which is electrically connected to the battery module 152 and is disposed in the battery housing 151. The battery management module 153 is used to control the charging and discharging of the battery module 152. Through the above arrangement, the wiring harness cost between the battery management module 153 and the battery module 152 can be reduced, and the battery housing 151 can also provide protection for the battery management module 153.

[0051] In this embodiment, the battery management module 153 is arranged on the front side of the battery module 152, and a plurality of plug-ins 154 connected to the battery management module 153 are also arranged on the front side of the battery housing 151. Through the above arrangement, the battery management module 153 can be connected to the electrical components outside the power battery 15 through the plug-in 154 arranged on the front side of the battery housing 151, and the length of the wire harness between the battery management module 153 and the plug-in 154 can be reduced, thereby reducing the cost of the wire harness.

[0052] like Figure 4 and Figure 7As shown, as an implementation, the all-terrain vehicle 100 includes an electrical component 22 and a fuel component 23, both of which are at least partially arranged on the frame 11. The electrical component 22 includes a charging port 221 and a wiring harness mechanism 222, the charging port 221 is used to supply power to the power battery 15, and the wiring harness mechanism 222 is used to connect the power battery 15 and the charging port 221. The fuel component 23 includes a fuel tank 231, a refueling port 232 and a fuel pipeline 233, the fuel tank 231 is connected to the range extender 142, and the refueling port 232 is connected to the fuel tank 231 through the fuel pipeline 233, that is, the fuel pipeline 233 is used to connect the refueling port 232 and the fuel tank 231, so that the fuel tank 231 can supply fuel to the range extender 142. In this embodiment, the fuel filler port 232 and the charging port 221 are distributed on both sides of the width direction of the all-terrain vehicle 100, so that the fuel filler port 232 and the charging port 221 can be set independently of each other to maximize the interval between the fuel filler port 232 and the charging port 221, thereby avoiding safety hazards caused by the small interval between the fuel line 233 and the wiring harness mechanism 222, which is beneficial to improving the safety of the all-terrain vehicle 100.

[0053] In this embodiment, the minimum distance D1 between the wiring harness mechanism 222 and the fuel pipeline 233 is set to be greater than or equal to 260 mm and less than or equal to 500 mm. Specifically, the minimum distance D1 between the wiring harness mechanism 222 and the fuel pipeline 233 is set to be greater than or equal to 320 mm and less than or equal to 440 mm. More specifically, the minimum distance D1 between the wiring harness mechanism 222 and the fuel pipeline 233 is set to 380 mm. Through the above setting, it is possible to prevent the wiring harness mechanism 222 and the fuel pipeline 233 from being too long, thereby preventing the wiring harness cost from being too high; it is also possible to prevent the wiring harness mechanism 222 and the fuel pipeline 233 from being too short, thereby preventing the high voltage current carried by the wiring harness mechanism 222 from igniting the fuel in the fuel pipeline 233, thereby improving the safety of the all-terrain vehicle 100.

[0054] As an implementation method, the charging port 221 extends substantially along the direction of the first preset straight line 2211, defining a reference plane 101 perpendicular to the height direction of the all-terrain vehicle 100, and the acute angle β formed by the first preset straight line 2211 and the reference plane 101 is set to be greater than or equal to 20° and less than or equal to 40°. Specifically, the acute angle β formed by the first preset straight line 2211 and the reference plane 101 can be set to be greater than or equal to 25° and less than or equal to 35°. More specifically, the acute angle β formed by the first preset straight line 2211 and the reference plane 101 can also be set to 30°. Through the above-mentioned setting, it is possible to prevent the acute angle β formed by the first preset straight line 2211 and the reference plane 101 from being too large, which is not conducive to the assembly between the charging gun and the charging port 221; it is also possible to prevent the acute angle β formed by the first preset straight line 2211 and the reference plane 101 from being set too small, which may cause the charging gun to fall off easily during the charging process. Thus, while improving the assembly stability between the charging gun and the charging port 221, the angle of the charging port 221 can be made convenient for the user to control the insertion and removal of the charging gun in the charging port 221, which is beneficial to improving the human-computer interactivity of the all-terrain vehicle 100.

[0055] In this embodiment, the refueling port 232 extends substantially along the direction of the second preset straight line 2321, and the acute angle γ formed by the second preset straight line 2321 and the reference plane 101 is set to be greater than or equal to 20° and less than or equal to 40°. Specifically, the acute angle γ formed by the second preset straight line 2321 and the reference plane 101 is set to be greater than or equal to 25° and less than or equal to 35°. More specifically, the acute angle γ formed by the second preset straight line 2321 and the reference plane 101 can also be set to 30°. Through the above setting, it is possible to prevent the acute angle γ formed by the second preset straight line 2321 and the reference plane 101 from being too large, which is not conducive to the assembly between the refueling gun and the refueling port 232; it is also possible to prevent the acute angle γ formed by the second preset straight line 2321 and the reference plane 101 from being too small, which causes the refueling gun to fall off easily during the refueling process, thereby improving the assembly stability between the refueling gun and the refueling port 232, and making the angle of the refueling port 232 convenient for the user to control the insertion and removal of the refueling gun in the refueling port 232, which is conducive to improving the human-machine interaction of the all-terrain vehicle 100.

[0056] As an implementation method, the charging port 221 is arranged close to the drive motor 141, and the refueling port 232 is arranged close to the range extender 142, so as to reduce the cost of the wiring harness mechanism 222 and the wiring harness cost between the charging port 221 and the power battery 15, and also reduce the length of the fuel line 233 and the length of the line between the fuel tank 231 and the range extender 142, thereby improving the space utilization and structural compactness of the electrical components 22 and the fuel components 23.

[0057] As an implementation method, the electrical component 22 also includes a controller assembly 223, which is connected to the charging port 221 and the power battery 15 respectively, so that the AC power output by the charging gun can be converted into DC power through the controller assembly 223, so as to charge the power battery 15. Among them, the controller assembly 223 can be set as a CDU (on-board power integration module, Conversion & Distribution Unit) module, and the controller assembly 223 includes at least a transformer and a charger. In addition, the controller assembly 223 can also convert the high-voltage DC power output by the power battery 15 into low-voltage DC power, so as to power the equipment on the all-terrain vehicle 100.

[0058] In this embodiment, the controller assembly 223 is at least partially disposed on the upper side of the drive motor 141, so that the controller assembly 223 can be disposed close to the charging port 221, which is beneficial to reducing the length of the wiring harness connecting the controller assembly 223 to the charging port 221 and the power battery 15, thereby reducing the production cost of the all-terrain vehicle 100.

[0059] As an implementation method, the all-terrain vehicle 100 further includes a seat assembly 17, and the seat assembly 17, the drive motor 141, and the range extender 142 are surrounded to form a storage space for accommodating the fuel tank 231. It should be noted that when the all-terrain vehicle 100 is set as an electric vehicle, the storage space can also be used as a storage space for the all-terrain vehicle 100, or the storage space can be used as an expansion space for the power battery 15, which can increase the battery capacity of the power battery 15 to improve the endurance of the all-terrain vehicle 100.

[0060] In this embodiment, the fuel tank 231 is arranged at the rear side of the seat assembly 17, and the fuel tank 231 and the range extender 142 are also arranged in a distributed manner along the width direction of the all-terrain vehicle 100. Specifically, the power battery 15 is arranged at the front side of the drive motor 141, and the fuel tank 231 is at least partially arranged between the drive motor 141 and the power battery 15. Through the above arrangement, the length of the pipeline between the fuel tank 231 and the range extender 142 can be reduced to improve the structural compactness of the fuel assembly 23, and the space between the drive motor 141 and the power battery 15 can be fully utilized to improve the space utilization of the all-terrain vehicle 100, which is conducive to improving the structural compactness of the all-terrain vehicle 100.

[0061] like Figure 8 As shown, as an implementation method, an inspection port 1721 is provided on the seat assembly 17, and the inspection port 1721 is provided close to the fuel tank 231, so that when the fuel assembly 23 fails, the fuel assembly 23 can be easily repaired through the inspection port 1721.

[0062] like Figure 8 and Fig. 9As shown, as an implementation, the electrical component 22 further includes a generator controller 224, which is connected to the range extender 142, and the generator controller 224 is also connected to the power battery 15. The generator controller 224 is used to start the range extender 142 and charge the power battery 15. The generator controller 224 is also connected to the drive motor 141, and the generator controller 224 obtains electrical energy through the range extender 142, and controls the drive motor 141 to work.

[0063] Specifically, the generator controller 224 is at least partially disposed on the front side of the range extender 142, and the generator controller 224 is disposed between the range extender 142 and the power battery 15. When viewed from the length direction of the all-terrain vehicle 100, the generator controller 224 and the range extender 142 at least partially overlap. Optionally, the generator controller 224 is at least partially disposed above the power battery 15, thereby shortening the length of the wiring harness mechanism 222 required for connecting the range extender 142 and the power battery 15, thereby reducing the cost of the wiring harness mechanism 222.

[0064] As an implementation method, a reference plane 101 perpendicular to the height direction of the all-terrain vehicle 100 is defined, the projection of the generator controller 224 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is the first projection plane, the projection of the axis of the front wheel 131 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is the projection line, the projection of the rear seat 172 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is the second projection plane, the minimum interval between the front end of the first projection plane and the projection line along the length direction of the all-terrain vehicle 100 is defined as the first interval L6, the minimum interval between the front end of the second projection plane and the projection line along the length direction of the all-terrain vehicle 100 is defined as the second interval L7, and the ratio between the first interval L6 and the second interval L7 is greater than or equal to 0.88 and less than or equal to 1.32. Specifically, the ratio between the first interval L6 and the second interval L7 is greater than or equal to 0.99 and less than or equal to 1.21. More preferably, the ratio between the first interval L6 and the second interval L7 can also be 1.1. The above arrangement can prevent the generator controller 224 from being too close to the front and interfering with the power battery 15. Since the range extender 142 is arranged behind the generator controller 224, the above arrangement keeps the generator controller 224 away from the heat source, thereby reducing the possibility of thermal failure of the generator controller 224. In addition, the convenience of maintenance of the generator controller 224 is improved.

[0065] As an optional implementation, the projection of the range extender 142 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is a third projection plane, and the minimum interval D2 between the rearmost end of the first projection plane and the frontmost end of the third projection plane is set to be greater than or equal to 192.8 mm and less than or equal to 289.2 mm. Specifically, the minimum interval D2 between the rearmost end of the first projection plane and the frontmost end of the third projection plane is set to be greater than or equal to 216.9 mm and less than or equal to 265.1 mm. More preferably, the minimum interval D2 between the rearmost end of the first projection plane and the frontmost end of the third projection plane is set to 241 mm. Since the range extender 142 provides energy for the all-terrain vehicle 100 by fuel-powered electricity, the range extender 142 will generate a lot of heat during the power generation process. The above setting can keep the generator controller 224 as far away from the heat source as possible to avoid damage to the generator controller 224. In addition, since the space occupied by the power battery 15 is large, the above setting can also avoid interference between the generator controller 224 and the power battery 15 when arranged.

[0066] Further, when viewed from the height direction of the all-terrain vehicle 100, the rear seat 172 and the generator controller 224 at least partially overlap. The rear seat 172 also includes a seat cushion 1722, which is at least partially disposed above the generator controller 224, and the seat cushion 1722 is detachably disposed on the vehicle frame 11, thereby improving the maintainability of the generator controller 224.

[0067] Specifically, the range extender 142 includes a generator 1422 , and the generator 1422 is disposed on a side of the range extender 142 facing the generator controller 224 , thereby shortening the length of the wiring harness mechanism 222 between the generator 1422 and the generator controller 224 , thereby reducing the production cost of the all-terrain vehicle 100 .

[0068] like Figure 8 and Fig.10 As shown, as an optional implementation, the generator controller 224 further includes an interface component 2241, and the interface component 2241 is used to connect the wiring harness mechanism 222. As can be seen from the foregoing, the generator controller 224 needs to be connected to the range extender 142, the power battery 15, and the drive motor 141, etc. In order to avoid the arrangement of the wiring harness mechanism 222 being too disordered, the interface component 2241 is arranged to face the rear of the all-terrain vehicle 100, that is, the interface component 2241 is arranged in the direction of the range extender 142, thereby shortening the length of the wiring harness mechanism 222 and reducing the production cost of the vehicle.

[0069] like Fig.11As shown, the electrical component 22 also includes a motor controller 225, which is used to control the movement of the drive motor 141. Since the drive motor 141 and the motor controller 225 have certain requirements for the working environment, in order to avoid the problem of thermal failure of the drive motor 141 and the motor controller 225, the present application makes the following improvements to the exhaust component 21.

[0070] As an implementation method, the exhaust assembly 21 is connected to the range extender 142. The exhaust assembly 21 includes an exhaust pipe 211 and a muffler 212 disposed at the rear end of the all-terrain vehicle 100. The two ends of the exhaust pipe 211 are respectively connected to the muffler 212 and the exhaust duct 1423 of the range extender 142. The passage opening of the exhaust duct 1423 is disposed on a side away from the drive motor 141. In this solution, the passage opening of the exhaust duct 1423 faces the left side of the all-terrain vehicle 100, thereby preventing the exhaust pipe 211 from extending in the direction of the drive motor 141, and preventing the exhaust pipe 211 from being overheated and affecting the operation of the drive motor 141 and the motor controller 225 and other components, especially to keep the exhaust assembly 21 away from the wiring harness mechanism 222, thereby improving the safety of the all-terrain vehicle 100.

[0071] Since the exhaust pipe 211 extends substantially along the length direction of the ATV 100 and passes through the accommodation space 1111 formed around the rear frame 111, in order to prevent the exhaust pipe 211 from overheating and affecting the drive motor 141, the motor controller 225 and the controller assembly 223, the exhaust pipe 211 needs to be arranged away from the above components. Specifically, the exhaust pipe 211 is arranged on a side of the range extender 132 away from the drive motor 141, and the exhaust pipe 211 also extends to the rear of the ATV 100.

[0072] As an implementation, the exhaust pipe 211 is at least partially disposed on the rear frame 111. A reference plane 101 perpendicular to the height direction of the all-terrain vehicle 100 is defined, the projection of the exhaust pipe 211 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is a first projection plane, the projection of the rear frame 111 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is a second projection plane, the maximum interval between the first projection plane and the second projection plane along the width direction of the all-terrain vehicle 100 is defined as a first width W1, the width of the second projection plane along the width direction of the all-terrain vehicle 100 is defined as a second width W2, and the ratio between the first width W1 and the second width W2 is greater than or equal to 0.1 and less than or equal to 0.3. Specifically, the ratio between the first width W1 and the second width W2 is greater than or equal to 0.12 and less than or equal to 0.27. More preferably, the ratio between the first width W1 and the second width W2 is greater than or equal to 0.14 and less than or equal to 0.24. The above arrangement prevents the exhaust pipe 211 from being too close to the rear frame 111 along the width direction of the all-terrain vehicle 100, resulting in the exhaust pipe 211 being exposed, or prevents the exhaust pipe 211 from interfering with the rear frame 111 during the arrangement process. In addition, the above arrangement prevents the exhaust pipe 211 from being too close to the drive motor 141, the motor controller 225 and other components, thereby affecting the performance of the drive motor 141. Through the above arrangement, the drive motor 141, the motor controller 225 and other components have a better working environment, thereby improving the rationality of the arrangement of the exhaust pipe 211.

[0073] As an implementation, the ATV 100 further includes a heat insulation assembly 28 , which is at least partially disposed between the muffler 212 and the motor controller 225 , thereby preventing the motor controller 225 from being affected by the high temperature of the muffler 212 and causing thermal failure.

[0074] Specifically, the heat insulation assembly 28 is at least partially arranged around the outer peripheral surface of the muffler 212, and the heat insulation assembly 28 is fixedly connected to the muffler 212, thereby optimizing the working environment of the drive motor 141, thereby improving the performance of the drive motor 141. Optionally, the heat insulation assembly 28 and the muffler 212 are fixed by a small group assembly and connected to the rear frame 111, thereby improving the assembly efficiency of the exhaust assembly 21.

[0075] Optionally, the thermal insulation component 28 is also at least partially disposed around the drive motor 141, the motor controller 225 and / or the controller assembly 223, so as to optimize the working environment of the above components and thereby improve their working performance.

[0076] More specifically, in order to improve the working performance of the driving motor 141 , the minimum distance between the driving motor 141 and the muffler 212 is set to be greater than or equal to 100 mm, thereby improving the working performance of the driving motor 141 .

[0077] As an implementation, when viewed from the width direction of the all-terrain vehicle 100, the range extender 142 and the drive motor 141 at least partially overlap. The projection of the range extender 142 on the longitudinal plane 102 along the width direction of the all-terrain vehicle 100 is defined as the range extender transverse projection, and the projection of the drive motor 141 on the longitudinal plane 102 along the width direction of the all-terrain vehicle 100 is defined as the drive motor transverse projection. The area of ​​the overlapping portion of the range extender transverse projection and the drive motor transverse projection is set to be greater than or equal to 402 cm 2 And less than or equal to 605cm 2 Specifically, the area of ​​the overlap between the range extender's lateral projection and the drive motor's lateral projection is set to be greater than or equal to 453 cm 2 And less than or equal to 554cm 2 Preferably, the overlapping area of ​​the range extender lateral projection and the drive motor lateral projection is set to 503 cm 2 . Since the range extender 142 has basically no space to move in the length direction of the all-terrain vehicle 100, if the area of ​​the overlapping part is too small, the drive motor 141 will be set too close to the rear side of the all-terrain vehicle 100, so that the distance between the drive motor 141 and the muffler 212 is too close, and the high temperature will have a certain impact on the drive motor 141 and the wiring harness mechanism 222. If the area of ​​the overlapping part is too large, it will cause interference between the drive motor 141 and the range extender 142 during the layout process. Through the above arrangement, while ensuring that the drive motor 141 and the range extender 142 are compactly arranged, it is also possible to eliminate the impact of high temperature on the drive motor 141 and improve the performance of the drive motor 141.

[0078] like Fig.12 and Fig.13 As shown, as an implementation, the motor controller 225 includes a first interface 2251 connected to the harness mechanism 222, the number of the first interfaces 2251 is set to be a plurality, and the first interfaces 2251 are set on the left side and / or the right side of the motor controller 225. The minimum distance Q1 between the first interface 2251 and the muffler 212 is set to be greater than or equal to 100 mm, so that the harness mechanism 222 is away from the heat source, thereby improving the safety of the all-terrain vehicle 100.

[0079] Furthermore, the controller assembly 223 is arranged above the motor controller 225 and is connected to the motor controller 225 through the harness mechanism 222. The controller assembly 223 includes a plurality of second interfaces 2231, and the second interfaces 2231 are all arranged to face the left side and / or right side of the all-terrain vehicle 100, that is, the second interfaces 2231 are arranged in the same direction as the first interfaces 2251, so as to facilitate the arrangement of the harness mechanism 222 between the controller assembly 223 and the motor controller 225, thereby reducing the length of the harness mechanism 222 between the controller assembly 223 and the motor controller 225, improving the structural compactness between the components and reducing the production cost of the all-terrain vehicle 100. The minimum distance Q2 between the second interface 2231 and the muffler 212 is also set to be greater than or equal to 100 mm, so as to keep the harness mechanism 222 away from the heat source, thereby improving the service life of the harness mechanism 222.

[0080] Optionally, the second interface 2231 is arranged to face the rear of the ATV 100, and the minimum distance Q2 between the second interface 2231 and the muffler 212 is set to be greater than or equal to 200 mm. Since the harness mechanism 222 has a certain flexibility, and the harness mechanism 222 has the possibility of deviating from the preset fixed position even after being fixed, when the harness mechanism 222 is connected to the second interface 2231, at least part of the harness mechanism 222 will extend in the direction of the muffler 212. The above arrangement allows a certain space for the harness mechanism 222 to bend between the second interface 2231 and the muffler 212, so as to avoid damage to the harness mechanism 222 due to the high temperature of the muffler 212, thereby ensuring the safety of the ATV 100.

[0081] As an implementation, the spacing D3 between the first interface 2251 and the second interface 2231 along the length direction of the all-terrain vehicle 100 is set to be greater than or equal to 64 mm and less than or equal to 96 mm. Specifically, the spacing D3 between the first interface 2251 and the second interface 2231 along the length direction is set to be greater than or equal to 72 mm and less than or equal to 88 mm. More preferably, the spacing D3 between the first interface 2251 and the second interface 2231 along the length direction is set to 80 mm. Since a wiring harness is connected between the controller assembly 223 and the motor controller 225, the above setting can shorten the length of the wiring harness mechanism 222, thereby reducing the production cost of the all-terrain vehicle 100.

[0082] Furthermore, when viewed from the height direction of the ATV 100 , the controller assembly 223 and the motor controller 225 at least partially overlap, thereby shortening the length of the wiring harness mechanism 222 between the controller assembly 223 and the motor controller 225 .

[0083] Among them, the lowermost end of the walking assembly 13 is basically located on the reference plane 101. As an implementation method, the spacing H2 between the lowermost end of the controller assembly 223 and the reference plane 101 is set to be greater than or equal to 770 mm and less than or equal to 940 mm. Specifically, the spacing H2 between the lowermost end of the controller assembly 223 and the reference plane 101 is set to be greater than or equal to 810 mm and less than or equal to 900 mm. More preferably, the spacing H2 between the lowermost end of the controller assembly 223 and the reference plane 101 is set to be equal to 855 mm. Thereby improving the wading performance of the controller assembly 223, and also avoiding the arrangement height of the controller assembly 223 being too high and interfering with the cargo box assembly 18.

[0084] Specifically, the controller assembly 223 is fixedly connected to the rear frame 111. There is an installation gap Q3 between the controller assembly 223 and the motor controller 225, and the height of the controller assembly 223 from the ground can be increased through the installation gap Q3. The rear frame 111 is also at least partially penetrated in the installation gap Q3, and along the height direction of the all-terrain vehicle 100, the end faces of both sides of the controller assembly 223 are fixedly connected to the rear frame 111, thereby improving the stability of the controller assembly 223. As an optional implementation, the installation gap Q3 is set to be greater than or equal to 48mm and less than or equal to 72mm. The installation gap Q3 is set to be greater than or equal to 54mm and less than or equal to 54mm. More preferably, the installation gap Q3 is set to be equal to 60mm. This avoids the interference between the controller assembly 223 and the cargo box assembly 18 caused by the installation gap Q3 being too large. If the installation gap Q3 is too small, the rear frame 111 for fixing cannot be set below the controller assembly 223. The above arrangement can not only ensure the stability of the controller assembly 223 , but also improve the waterproofness of the controller assembly 223 .

[0085] As an implementation method, the range extender 142 and the drive motor 141 are arranged in the width direction of the all-terrain vehicle 100, and the motor controller 225 and the drive motor 141 are arranged in the height direction of the all-terrain vehicle 100. Specifically, the motor controller 225 is arranged above the drive motor 141. The above arrangement makes the load distribution of the all-terrain vehicle 100 uniform and improves the overall balance of the all-terrain vehicle 100. In addition, the motor controller 225 is arranged above the drive motor 141 to facilitate the inspection and maintenance of the motor controller 225.

[0086] Furthermore, the transmission assembly 16 further includes a reducer 161 and a transmission shaft 162. The reducer 161 is arranged on a side of the driving motor 141 close to the range extender 142. In the present application, the range extender 142 is arranged on the left side of the driving motor 141. The reducer 161 is arranged between the driving motor 141 and the range extender 142 so that the reducer 161 is transmission-connected to the transmission shaft 162. Through the above arrangement, the connecting components between the reducer 161 and the transmission shaft 162 can be reduced, thereby improving the compactness of the transmission assembly 16.

[0087] like Fig.11 As shown, specifically, the drive motor 141, the motor controller 225 and the reducer 16 are integrated and constitute a drive assembly. The drive assembly is at least partially arranged on the rear frame 111. A reference plane 101 perpendicular to the height direction of the all-terrain vehicle 100 is defined, and the projection of the drive assembly on the reference plane 101 along the height direction of the all-terrain vehicle 100 is a first projection plane, and the projection of the rear frame 111 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is a second projection plane. The width of the first projection plane extending along the width direction of the all-terrain vehicle 100 is defined as a first width W3, and the width of the second projection plane extending along the width direction of the all-terrain vehicle 100 is defined as a second width W2. As an optional implementation, the ratio of the first width W3 to the second width W2 is greater than or equal to 0.36 and less than or equal to 0.54. Further, the ratio of the first width W3 to the second width W2 is greater than or equal to 0.4 and less than or equal to 0.5. Preferably, the ratio of the first width W3 to the second width W2 is greater than or equal to 0.43 and less than or equal to 0.47. If the ratio of the first width W3 to the second width W2 is too large, the width of the drive assembly extending along the width direction of the all-terrain vehicle 100 is too large, and then the space occupied by the drive assembly on the frame 11 is too large, making it easy for the drive assembly to interfere with other components on the frame 11. Through the above arrangement, the space occupied by the drive assembly is reduced, and the compactness of the whole vehicle is improved.

[0088] More specifically, along the width direction of the ATV 100, the center of gravity of the drive assembly and the center of gravity of the range extender 142 are respectively arranged on both sides of the transmission shaft 162. Through the above arrangement, the load distribution in the width direction of the ATV 100 is uniform, and the overall balance of the ATV 100 is improved.

[0089] Optionally, the range extender 142 is at least partially arranged in front of the drive assembly, and the drive assembly and the range extender 142 at least partially overlap when viewed along the length direction of the all-terrain vehicle 100. Since the range extender 142 and the drive motor 141 are arranged substantially along the width direction of the all-terrain vehicle 100, the above arrangement makes the center of gravity of the range extender 142 and the drive assembly closer to the center of the all-terrain vehicle 100, ensuring that the center of gravity of the all-terrain vehicle 100 is centered, and can also avoid interference between the all-terrain vehicle 100 and the components on both sides, thereby improving the compactness of the entire vehicle.

[0090] In this embodiment, the ATV 100 further includes a fuel tank 231, which is disposed on the right side of the range extender 142, and the fuel tank 231 and the drive assembly are arranged along the length direction of the ATV 100. Through the above arrangement, the load distribution in the length direction and the width direction of the ATV 100 is uniform, thereby improving the overall balance of the ATV 100.

[0091] As an implementation method, the rear frame 111 is surrounded by a receiving space 1111, and the drive assembly is arranged in the receiving space 1111. A reference plane 101 perpendicular to the height direction of the all-terrain vehicle 100 is defined, and the projection of the receiving space 1111 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is defined as a first projection plane, and the projection of the drive assembly on the reference plane 101 along the height direction of the all-terrain vehicle 100 is defined as a second projection plane, and the ratio between the area of ​​the first projection plane and the area of ​​the second projection plane is greater than or equal to 4 and less than or equal to 6. Further, the ratio between the area of ​​the first projection plane and the area of ​​the second projection plane is greater than or equal to 4.5 and less than or equal to 5.5. More preferably, the ratio between the area of ​​the first projection plane and the area of ​​the second projection plane can also be 5. It should be noted that if the ratio between the area of ​​the first projection plane and the area of ​​the second projection plane is too large, the space occupied by the drive assembly is too large, and it is easy to interfere with other components on the frame 11. Through the above arrangement, the space occupied by the drive assembly is reduced and the compactness of the whole vehicle is improved.

[0092] As an implementation method, the width of the range extender 142 and the drive combination extending in the width direction of the all-terrain vehicle 100 is defined as a third width W4, and the ratio of the third width W4 to the second width W2 is greater than or equal to 0.53 and less than or equal to 0.8. Further, the ratio of the third width W4 to the second width W2 is greater than or equal to 0.6 and less than or equal to 0.73. More preferably, the ratio of the third width W4 to the second width W2 is greater than or equal to 0.63 and less than or equal to 0.69. If the ratio between the third width W4 and the second width W2 is too large, the width of the range extender 142 and the drive combination extending in the width direction of the all-terrain vehicle 100 is too large, so that the space occupied by the range extender 142 and the drive combination is too large, and the range extender 142 and the drive combination are prone to interfere with other components on the frame 11. Through the above arrangement, the space occupied by the range extender 142 and the drive combination is reduced, and the compactness of the entire vehicle is improved.
