[0042] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the specific embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] As shown in Figures 1 to 4, an all-terrain vehicle 100 is shown. The all-terrain vehicle 100 includes a frame 11, a body cover 12, a running 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 serves as the basic framework of the all-terrain vehicle 100 and is used to support the body cover 12, the running 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 disposed on the frame 11. When the body cover 12 and the frame 11 are connected, they form a protective frame for protecting the internal components of the all-terrain vehicle 100. The running assembly 13 is at least partially disposed below the frame 11 and includes a front wheel 131 and a rear wheel 132. The power assembly 14 is supported by the frame 11 and is connected to at least one of the front wheels 131 and the rear wheels 132 via a transmission assembly 16, enabling the power assembly 14 to drive the ATV 100. A power battery 15 is at least partially mounted on the frame 11 and can also provide energy for the power assembly 14. A seat assembly 17 is at least partially mounted on the frame 11 and provides support for the driver and passenger. A cargo box assembly 18 is at least partially mounted on the rear side of the frame 11 and is used to carry cargo on the ATV 100. Specifically, the frame 11 includes a rear frame 111 disposed at the rear of the frame 11. The rear frame 111 defines a storage space 1111, within which the power assembly 14 is at least partially mounted. To clarify the technical aspects of the present invention, the front, rear, left, right, top, and bottom sides are defined as shown in FIG1 . In this application, the front-to-back direction of the ATV 100 refers to the length direction of the ATV 100 , the left-to-right direction of the ATV 100 refers to the width direction of the ATV 100 , and the up-down direction of the ATV 100 refers to the height direction of the ATV 100 .

[0044] As one implementation, the power assembly 14 includes a drive motor 141 and a range extender 142, both of which are at least partially disposed within the accommodation space 1111. The range extender 142 provides energy for the drive motor 141, which in turn drives at least one of the front wheels 131 and the rear wheels 132. The power battery 15 is electrically connected to the range extender 142 to charge the power battery 15. The power battery 15 is also electrically connected to the drive motor 141 to provide energy to the drive motor 141.

[0045] As shown in FIG3 , 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 within the first projection plane is a second projection plane. The ratio of the area of ​​the second projection plane to the area of ​​the first projection plane ranges from 0.26 to 0.49. The first projection surface is the projection of the accommodation space 1111 formed by the rear frame 111 onto the reference plane 101 along the height direction of the ATV 100. The range extender 142 and the drive motor 141 both have outer shells. The second projection surface is the combined projection of the outer shells of the range extender 142 and the drive motor 141 onto the reference plane 101 along the height direction of the ATV 100. This means that the second projection surface excludes the projection of structures such as the wiring harness of the range extender 142 and the drive motor 141, and only includes the projection of the main bodies 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 ranges from 0.3 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. In this way, while meeting the arrangement requirements of the range extender 142 and the drive motor 141, it is beneficial to the arrangement of other components of the all-terrain vehicle 100, and interference between the power assembly 14 and other components of the all-terrain vehicle 100 is prevented, thereby improving the space utilization and structural compactness of the all-terrain vehicle 100.

[0046] In this embodiment, the drive motor 141 and the range extender 142 at least partially overlap when viewed across the width of the ATV 100. When viewed along the length of the ATV 100, the drive motor 141 and the range extender 142 at least partially overlap. This arrangement reduces the space occupied by the drive motor 141 and the range extender 142 without affecting their normal operation, making the structure of the drive motor 141 and the range extender 142 more compact and improving the space utilization and structural compactness of the ATV 100. Specifically, the drive motor 141 is at least partially located behind the range extender 142.

[0047] As an implementation, the drive motor 141 and the range extender 142 are distributed along the width of the ATV 100. Specifically, along the width of the ATV 100, the drive motor 141 is at least partially disposed on a first side of the ATV 100, and the range extender 142 is at least partially disposed on a second side of the ATV 100, away from the first side. The first side can be the left or right side of the ATV 100, and the second side can be the right or left side of the ATV 100. The first and second sides only need to be different sides of the ATV 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 arranged substantially symmetrically 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 opposite sides of the longitudinal plane 102. This makes the load of the drive motor 141 and the range extender 142 on the all-terrain vehicle 100 more uniform. That is, by distributing the drive motor 141 and the range extender 142 along the width direction of the all-terrain vehicle 100, the center of gravity of the all-terrain vehicle 100 can be arranged closer to the longitudinal plane 102, thereby improving the driving stability of the all-terrain vehicle 100.

[0048] As an implementation, the ATV 100 further includes an intake assembly 19 and an exhaust assembly 21. The intake assembly 19 is connected to the intake duct of the range extender 142, and the exhaust assembly 21 is connected to the exhaust duct of the range extender 142. The intake assembly 19 is used to deliver ambient air to the range extender 142, while the exhaust assembly 21 is used to exhaust exhaust gas generated by the operation of the range extender 142. The range extender 142 includes a crankshaft mechanism 1421, which extends substantially along the length of the ATV 100. Along the width of the ATV 100, the intake assembly 19 and the exhaust assembly 21 are respectively disposed on either side of the crankshaft mechanism 1421. Specifically, the exhaust assembly 21 is at least partially disposed on a side of the range extender 142 away from the drive motor 141, while the intake assembly 19 is at least partially disposed on a side of the range extender 142 closer to the drive motor 141. Specifically, the exhaust assembly 21 is disposed closer to the outside of the ATV 100, while the intake assembly 19 is disposed closer to the inside of the ATV 100. This arrangement allows the exhaust assembly 21 to be shortened while meeting the performance requirements of the range extender 142, thereby improving the compactness of the exhaust assembly 21. It also prevents the short distance between the exhaust assembly 21 and the drive motor 141 from affecting the proper operation of the drive motor 141, thereby enhancing the operational 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. The length L1 of the exhaust pipe 211 along the exhaust direction ranges from 800 mm to 1300 mm. Specifically, the length L1 of the exhaust pipe 211 along the exhaust direction can be set to 1031 mm. The exhaust direction refers to the direction in which exhaust gas generated by the range extender 142 travels through the exhaust pipe 211. This arrangement allows the exhaust assembly 21 to be shortened while meeting the performance requirements of the range extender 142, thereby improving the compactness of the exhaust assembly 21.

[0049] As shown in FIG4 , as one implementation, the vehicle frame 11 further includes a mid-frame 112 disposed between the front wheel 131 and the rear wheel 132. The mid-frame 112 defines a circumferential accommodation space 1121. The power battery 15 is at least partially disposed within the accommodating space 1121. The power battery 15 is also at least partially disposed beneath 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 of the ATV 100 is greater than the length of one of the rows of seats along the length of the ATV 100. Furthermore, a reference plane 101 perpendicular to the height of the ATV 100 is defined. The projection of the power battery 15 along the height of the ATV 100 onto the reference plane 101 is referred to as a first projection plane, and the projection of the seat assembly 17 along the height of the ATV 100 onto the first projection plane is referred to as a second projection plane. The ratio of the area of ​​the second projection plane to the area of ​​the first projection plane is in a range of 0.34 to 0.65. The second projection surface refers to the total projection of the seat cushions of all seats in the seat assembly 17 onto the first projection surface along the height of the ATV 100. Specifically, the ratio of the area of ​​the second projection surface to the area of ​​the first projection surface ranges from 0.41 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. This arrangement increases the volume of the power battery 15, thereby increasing its capacity and thus improving the endurance of the ATV 100, while meeting the requirements for the layout of components on the front and rear sides of the seat assembly 17. It also improves the space utilization of the power battery 15 within the ATV 100, making the ATV 100 more compact. Furthermore, this arrangement prevents the relative position of the power assembly 15 and seat assembly 17 from affecting the riding experience of the driver and / or passengers, thereby improving the human-machine interaction and comfort of the ATV 100.

[0050] In this embodiment, the seat assembly 17 includes a front seat 171 and a rear seat 172 disposed behind the front seat 171. The front seat 171 includes a front seat cushion 1711, the projection of which on the first projection plane along the height direction of the ATV 100 is a third projection plane. The rear seat 172 includes a seat cushion 1722, the projection of which on the first projection plane along the height direction of the ATV 100 is a fourth projection plane. The ratio of the area of ​​the third projection plane to the area of ​​the first projection plane ranges from 0.24 to 0.47, and the ratio of the area of ​​the fourth projection plane to the area of ​​the first projection plane ranges from 0.1 to 0.18. Specifically, the ratio of the area of ​​the third projection plane to the area of ​​the first projection plane ranges from 0.3 to 0.42, and the ratio of the area of ​​the fourth projection plane to the area of ​​the first projection plane ranges from 0.12 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 interfering with the layout of components such as the brake and accelerator in front of the front seats 171, and it is also possible to prevent the power battery 15 from interfering with the layout of components such as the power assembly 14 behind the rear seats 172. This increases the volume of the power battery 15 while meeting the layout requirements of components such as the power assembly 14, thereby improving the endurance and structural compactness of the all-terrain vehicle 100.

[0051] As an implementation, the length of the power battery 15 along the length of the ATV 100 is set as the battery length L2. The projection of the axis of the front wheel 131 along the height direction of the ATV 100 onto the reference plane 101 is a first projection line. The projection of the axis of the rear wheel 132 along the height direction of the ATV 100 onto the reference plane 101 is a second projection line. The distance between the first projection line and the second projection line along the length of the ATV 100 is set as the axle distance L3. The ratio of the battery length L2 to the axle distance L3 ranges from 0.17 to 0.34. Specifically, the ratio of the battery length L2 to the axle distance L3 ranges from 0.21 to 0.3. More specifically, the ratio of the battery length L2 to the axle distance L3 can also be 0.26.

[0052] In this embodiment, the projection of the power battery 15 on the reference plane 101 along the height direction of the ATV 100 is defined as a 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 ATV 100 is defined as 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 ATV 100 is defined as a second distance L5. The ratio of the first distance L4 to the second distance L5 ranges from 0.61 to 1.14. Specifically, the ratio of the first distance L4 to the second distance L5 ranges from 0.74 to 1. More specifically, the ratio of the first distance L4 to the second distance L5 can also be 0.88.

[0053] 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, interference may occur between the front wheel 131 and components on the front side of the ATV 100, and / or between the rear wheel 132 and components on the rear side of the ATV 100. Therefore, the above arrangement can improve the compactness of the ATV 100 and enhance the driving stability of the ATV 100 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.

[0054] As shown in Figures 4, 5, and 6, as one implementation, the body cover 12 includes a guard plate structure 121, which is disposed below 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. The power battery 15 is at least partially disposed within the heat dissipation space 1211. The heat dissipation space 1211 is also connected to the outside world. This allows air to flow from the outside world into the heat dissipation space 1211 during travel of the all-terrain vehicle 100, thereby cooling the power battery 15 within the heat dissipation space 1211. This improves the heat dissipation effect on the power battery 15 and facilitates stable operation of the power battery 15.

[0055] In this embodiment, the underside of the mid-frame 112 is provided with a plurality of connection points 1122. The power battery 15 is fixedly connected to the mid-frame 112 via the connection points 1122. This allows the power battery 15 to be installed from the underside of the ATV 100 onto the mid-frame 112, thereby facilitating the removal and installation of the power battery 15 without having to remove other components. Furthermore, the underside of the mid-frame 112 is provided with positioning points 1123. The positioning points 1123 are used to limit the relative position between the mid-frame 112 and the power battery 15. After the mid-frame 112 and the power battery 15 are positioned via the positioning points 1123, the power battery 15 is fixedly connected to the mid-frame 112 via the connection points 1122, thereby improving the installation accuracy of the power battery 15 and the mid-frame 112. Among them, 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-frame 112.

[0056] As an implementation, the lowest end of the power battery 15 is positioned below the lowest end of the mid-mounted frame 112, thereby positioning the lowest end of the power battery 15 below the frame 11. This lowers the center of gravity of the all-terrain vehicle 100, thereby improving the driving stability and maneuverability of the all-terrain vehicle 100. In this embodiment, the lowest ends of the front wheels 131 and rear wheels 132 are substantially located above the reference plane 101, and the minimum distance H1 between the power battery 15 and the reference plane 101 ranges from 220 mm to 420 mm. 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 ranges from 270 mm 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 arrangement, it is possible to avoid the ground clearance of the power battery 15 being too high, which would be detrimental to lowering the center of gravity of the all-terrain vehicle 100, thereby improving the driving stability and maneuverability 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 would reduce the passability of the all-terrain vehicle 100, thereby meeting the driving requirements of the all-terrain vehicle 100 on complex terrain.

[0057] As an implementation, transmission assembly 16 includes a transmission shaft 162 and a speed reducer 161. Speed ​​reducer 161 is disposed on drive motor 141 and is in transmission connection with drive motor 141. Speed ​​reducer 161 is also rotationally connected to transmission shaft 162. Transmission shaft 162 is also transmission-connected to at least one of front wheel 131 and rear wheel 132. Thus, drive motor 141 can be transmission-connected to at least one of front wheel 131 and rear wheel 132, thereby enabling movement of all-terrain vehicle 100. Speed ​​reducer 161 is also at least partially disposed between drive motor 141 and range extender 142, thereby improving the structural compactness of power assembly 14 and transmission assembly 16.

[0058] As an implementation, a clearance portion 1511a is formed on the upper side of the power battery 15. The clearance portion 1511a is used to clear the transmission shaft 162, and the clearance portion 1511a extends generally along the extension direction of the transmission shaft 162. The transmission shaft 162 extends generally along the length of the ATV 100. This arrangement allows the power battery 15 to be positioned below the transmission shaft 162 without interfering with the transmission shaft 162, thereby facilitating the normal operation of the power battery 15 and transmission shaft 162 and improving their operational stability. Furthermore, the provision of the clearance portion 1511a reduces the distance between the power battery 15 and transmission shaft 162, thereby making the structure of the power battery 15 and transmission shaft 162 more compact and thereby improving the structural compactness of the ATV 100.

[0059] 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 formed with an avoidance portion 1511a. The acute angle α formed by the upper surface 1511b and the axis of the transmission shaft 162 ranges from 1° to 5°. Specifically, the acute angle α ranges from 2° 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 be broken, thereby improving the service life and working stability of the transmission assembly 16, and further improving the safety of the all-terrain vehicle 100.

[0060] 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, any battery module 152 that meets the assembly requirements 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 achieving 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, thereby making the load distribution of the power battery 15 on both sides of the avoidance portion 1511a 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, preventing the battery module 152 from being damaged and causing safety hazards, thereby improving the safety of the all-terrain vehicle 100.

[0061] In this embodiment, the battery housing 151 includes a detachably connected upper cover 1511 and a bottom housing 1512, which facilitates the disassembly and assembly of the battery module 152. This allows the power battery 15 to select different battery modules 152 based on the specific vehicle type, thereby improving the versatility and modularity of the power battery 15. Specifically, the relief portion 1511a is provided on the upper cover 1511, requiring only the upper cover 1511 of the battery housing 151 to be machined. This reduces the difficulty of machining the battery housing 151 and improves machining efficiency. It also prevents interference between the relief portion 1511a and the battery module 152, facilitating the normal operation of the battery module 152.

[0062] As an implementation, the power battery 15 also includes a battery management module 153, which is electrically connected to the battery module 152 and housed within the battery housing 151. The battery management module 153 is used to control the charging and discharging of the battery module 152. This arrangement reduces wiring costs between the battery management module 153 and the battery module 152, and the battery housing 151 also provides protection for the battery management module 153.

[0063] In this embodiment, the battery management module 153 is disposed 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 disposed on the front side of the battery housing 151. This arrangement allows the battery management module 153 to be connected to external electrical components of the power battery 15 via the plug-ins 154 disposed on the front side of the battery housing 151, while also reducing the length of the wiring harness between the battery management module 153 and the plug-ins 154, thereby lowering wiring harness costs.

[0064] As shown in Figures 4 and 7 , as one implementation, the all-terrain vehicle 100 includes an electrical assembly 22 and a fuel assembly 23, both of which are at least partially mounted on the vehicle frame 11. The electrical assembly 22 includes a charging port 221 and a wiring harness 222. The charging port 221 is used to supply power to the power battery 15, and the wiring harness 222 is used to connect the power battery 15 to the charging port 221. The fuel assembly 23 includes a fuel tank 231, a refueling port 232, and a fuel line 233. The fuel tank 231 is connected to the range extender 142, and the refueling port 232 is connected to the fuel tank 231 via the fuel line 233. Specifically, the fuel line 233 connects the refueling port 232 to the fuel tank 231, enabling the fuel tank 231 to 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, so as to maximize the distance between the fuel filler port 232 and the charging port 221, thereby avoiding safety hazards caused by the distance between the fuel line 233 and the wiring harness mechanism 222 being too small, which is beneficial to improving the safety of the all-terrain vehicle 100.

[0065] In this embodiment, the minimum distance D1 between the wiring harness mechanism 222 and the fuel line 233 ranges from 260 mm to 500 mm. Specifically, the minimum distance D1 between the wiring harness mechanism 222 and the fuel line 233 ranges from 320 mm to 440 mm. More specifically, the minimum distance D1 between the wiring harness mechanism 222 and the fuel line 233 is set to 380 mm. This configuration prevents the wiring harness mechanism 222 from being too long, which would result in higher wiring harness costs; it also prevents the wiring harness mechanism 222 from being too short, which would cause the high-voltage current carried by the wiring harness mechanism 222 to ignite the fuel in the fuel line 233, thereby improving the safety of the all-terrain vehicle 100.

[0066] As an implementation, the charging port 221 extends substantially along a first predetermined straight line 2211, defining a reference plane 101 perpendicular to the height direction of the ATV 100. The acute angle β formed between the first predetermined straight line 2211 and the reference plane 101 ranges from 20° to 40°. Specifically, the acute angle β formed between the first predetermined straight line 2211 and the reference plane 101 ranges from 25° to 35°. More specifically, the acute angle β formed between the first predetermined straight line 2211 and the reference plane 101 can also be set to 30°. Through the above 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. In this way, 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.

[0067] In this embodiment, the fuel filler port 232 extends substantially along a second predetermined straight line 2321. The acute angle γ formed between the second predetermined straight line 2321 and the reference plane 101 ranges from 20° to 40°. Specifically, the acute angle γ formed between the second predetermined straight line 2321 and the reference plane 101 ranges from 25° to 35°. More specifically, the acute angle γ formed between the second predetermined straight line 2321 and the reference plane 101 can be set to 30°. This arrangement prevents the acute angle γ formed between the second predetermined straight line 2321 and the reference plane 101 from being too large, thereby hindering the assembly between the fuel filler nozzle and the fuel filler port 232. It also prevents the acute angle γ formed between the second predetermined straight line 2321 and the reference plane 101 from being too small, thereby preventing the fuel filler nozzle from falling off during refueling. This improves the assembly stability between the fuel filler nozzle and the fuel filler port 232 while also facilitating the user's manipulation of inserting and removing the fuel filler nozzle from the fuel filler port 232, thereby enhancing the user-machine interface of the all-terrain vehicle 100.

[0068] As an implementation method, the charging port 221 is arranged close to the drive motor 141, and the fuel 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.

[0069] As an implementation, the electrical component 22 also includes a controller assembly 223, which is connected to the charging port 221 and the power battery 15. This allows the controller assembly 223 to convert the AC power output from the charging gun into DC power, thereby charging the power battery 15. The controller assembly 223 can be configured as a CDU (Conversion & Distribution Unit), which includes at least a transformer and a charger. Furthermore, the controller assembly 223 can convert the high-voltage DC power output from the power battery 15 into low-voltage DC power, thereby powering devices on the all-terrain vehicle 100.

[0070] 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.

[0071] As an implementation, the ATV 100 further includes a seat assembly 17. The seat assembly 17, the drive motor 141, and the range extender 142 surround a storage space for accommodating the fuel tank 231. It should be noted that when the ATV 100 is configured as an electric vehicle, the storage space can also serve as storage space for the ATV 100, or as expansion space for the power battery 15, thereby increasing the battery capacity of the power battery 15 and improving the endurance of the ATV 100.

[0072] In this embodiment, the fuel tank 231 is located behind the seat assembly 17. The fuel tank 231 and the range extender 142 are also distributed across the width of the ATV 100. Specifically, the power battery 15 is located in front of the drive motor 141, with the fuel tank 231 at least partially positioned between the drive motor 141 and the power battery 15. This arrangement not only reduces the length of the piping between the fuel tank 231 and the range extender 142, thereby improving the compactness of the fuel assembly 23, but also fully utilizes the space between the drive motor 141 and the power battery 15, thereby improving the space utilization of the ATV 100 and enhancing the compactness of the ATV 100.

[0073] As shown in FIG8 , as an implementation method, an inspection port 1721e is provided on the seat assembly 17. The inspection port 1721e is provided close to the fuel tank 231 so that the fuel assembly 23 can be easily repaired through the inspection port 1721e in the event of a failure of the fuel assembly 23.

[0074] As shown in Figures 8 and 9 , as one implementation, the electrical assembly 22 also includes a generator controller 224. The generator controller 224 is connected to the range extender 142 and 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. The generator controller 224 obtains electrical energy from the range extender 142 and uses this energy to control the operation of the drive motor 141.

[0075] As an implementation, the generator controller 224 is at least partially disposed on the front side of the range extender 142, between the range extender 142 and the power battery 15. When viewed along the length of the all-terrain vehicle 100, the generator controller 224 and the range extender 142 at least partially overlap. Alternatively, the generator controller 224 may be at least partially disposed above the power battery 15, thereby shortening the length of the wiring harness 222 required to connect the range extender 142 and the power battery 15 and reducing the cost of the wiring harness 222.

[0076] As an implementation, a reference plane 101 perpendicular to the height of the ATV 100 is defined. The projection of the generator controller 224 on the reference plane 101 along the height of the ATV 100 is defined as a first projection plane. The projection of the axis of the front wheel 131 on the reference plane 101 along the height of the ATV 100 is defined as a projection line. The projection of the rear seat 172 on the reference plane 101 along the height of the ATV 100 is defined as a second projection plane. The minimum distance between the front end of the first projection plane and the projection line along the length of the ATV 100 is defined as a first distance L6. The minimum distance between the front end of the second projection plane and the projection line along the length of the ATV 100 is defined as a second distance L7. The ratio between the first distance L6 and the second distance L7 ranges from 0.88 to 1.32. Specifically, the ratio between the first distance L6 and the second distance L7 ranges from 0.99 to 1.21. More preferably, the ratio between the first distance L6 and the second distance L7 can be 1.1. This arrangement prevents the generator controller 224 from being positioned too far forward and interfering with the power battery 15. Since the range extender 142 is located behind the generator controller 224, this arrangement keeps the generator controller 224 away from heat sources, thereby reducing the possibility of thermal failure of the generator controller 224. Furthermore, the generator controller 224 is easier to maintain.

[0077] As an optional implementation, the projection of the range extender 142 on the reference plane 101 along the height of the ATV 100 forms a third projection plane. The minimum distance D2 between the rearmost end of the first projection plane and the frontmost end of the third projection plane ranges from 192.8 mm to 289.2 mm. Specifically, the minimum distance D2 between the rearmost end of the first projection plane and the frontmost end of the third projection plane ranges from 216.9 mm to 265.1 mm. More preferably, the minimum distance D2 between the rearmost end of the first projection plane and the frontmost end of the third projection plane is set to 241 mm. Because the range extender 142 generates energy for the ATV 100 through fuel-fired power generation, it generates considerable heat during the power generation process. This arrangement allows the generator controller 224 to be positioned as far away from heat sources as possible, preventing damage to the generator controller 224. Furthermore, since the power battery 15 occupies a large space, this arrangement also prevents interference between the generator controller 224 and the power battery 15 during placement.

[0078] As an implementation, when viewed from the height of the ATV 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. The seat cushion 1722 is detachably mounted on the vehicle frame 11, thereby improving the maintainability of the generator controller 224.

[0079] As an implementation, 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 .

[0080] As shown in Figures 8 and 10, as an optional implementation, the generator controller 224 further includes an interface assembly 2241, which is used to connect to the wiring harness mechanism 222. As previously mentioned, the generator controller 224 needs to be connected to the range extender 142, the power battery 15, the drive motor 141, etc. To avoid an excessively cluttered arrangement of the wiring harness mechanism 222, the interface assembly 2241 is positioned toward the rear of the all-terrain vehicle 100, that is, toward the range extender 142. This shortens the length of the wiring harness mechanism 222 and, in turn, reduces the production cost of the vehicle.

[0081] As shown in Figure 11, the electrical assembly 22 also includes a motor controller 225, which is used to control the movement of the drive motor 141. Because 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 has made the following improvements to the exhaust assembly 21.

[0082] As an implementation, the exhaust assembly 21 is connected to the range extender 142. The exhaust assembly 21 includes an exhaust pipe 211 and a muffler 212 located at the rear end of the ATV 100. The ends of the exhaust pipe 211 are connected to the muffler 212 and the exhaust duct 1423 of the range extender 142, respectively. The opening of the exhaust duct 1423 is located on a side away from the drive motor 141. In this embodiment, the opening of the exhaust duct 1423 faces the left side of the ATV 100, thereby preventing the exhaust pipe 211 from extending toward the drive motor 141. This prevents the exhaust pipe 211 from overheating and potentially affecting the operation of components such as the drive motor 141 and the motor controller 225. In particular, this ensures that the exhaust assembly 211 is kept away from the wiring harness 222, thereby improving the safety of the ATV 100.

[0083] Because exhaust pipe 211 extends substantially along the length of ATV 100 and penetrates the accommodation space 1111 formed by rear frame 111, exhaust pipe 211 needs to be positioned away from the drive motor 141, motor controller 225, and controller assembly 223 to prevent excessive temperatures from affecting these components. Specifically, exhaust pipe 211 is positioned on the side of range extender 132 away from the drive motor 141 and extends toward the rear of ATV 100.

[0084] 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 of the ATV 100 is defined. The projection of the exhaust pipe 211 onto the reference plane 101 along the height of the ATV 100 is defined as a first projection plane. The projection of the rear frame 111 onto the reference plane 101 along the height of the ATV 100 is defined as a second projection plane. The maximum distance between the first projection plane and the second projection plane along the width of the ATV 100 is defined as a first width W1. The width of the second projection plane along the width of the ATV 100 is defined as a second width W2. The ratio between the first width W1 and the second width W2 ranges from 0.1 to 0.3. Specifically, the ratio between the first width W1 and the second width W2 ranges from 0.12 to 0.27. More preferably, the ratio between the first width W1 and the second width W2 ranges from 0.14 to 0.24. This arrangement prevents the exhaust pipe 211 from being too close to the rear frame 111 along the width of the ATV 100, potentially exposing the exhaust pipe 211, or interfering with the rear frame 111 during layout. Furthermore, this arrangement prevents the exhaust pipe 211 from being too close to components such as the drive motor 141 and the motor controller 225, potentially affecting the performance of the drive motor 141. This arrangement provides a more optimal operating environment for components such as the drive motor 141 and the motor controller 225, thereby enhancing the rationality of the exhaust pipe 211 layout.

[0085] 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.

[0086] As an implementation, the heat insulation assembly 28 is disposed at least partially around the outer circumference of the muffler 212 and is fixedly connected to the muffler 212, thereby optimizing the operating environment of the drive motor 141 and improving the performance of the drive motor 141. Optionally, the heat insulation assembly 28 and the muffler 212 are fixed together by subassembly and connected to the rear frame 111, thereby improving the assembly efficiency of the exhaust assembly 21.

[0087] As an implementation method, 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, thereby optimizing the working environment of the above components and thereby improving their working performance.

[0088] As an implementation manner, in order to improve the working performance of the drive motor 141 , the minimum distance between the drive motor 141 and the muffler 212 is set to be greater than or equal to 100 mm, thereby improving the working performance of the drive motor 141 .

[0089] As an implementation, when viewed from the width of the ATV 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 of the ATV 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 of the ATV 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 402 cm. 2 Up to 605cm 2 Specifically, the overlapping area of ​​the range extender's lateral projection and the drive motor's lateral projection is 453cm 2 Up to 554cm 2 More preferably, the area of ​​the overlap between the range extender's transverse projection and the drive motor's transverse projection is set to 503cm 2 . Since the range extender 142 basically has 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 biased to the rear side of the all-terrain vehicle 100, thereby causing the distance between the drive motor 141 and the muffler 212 to be 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 can also eliminate the impact of high temperature on the drive motor 141 and improve the performance of the drive motor 141.

[0090] As shown in Figures 12 and 13 , as one implementation, the motor controller 225 includes a first interface 2251 for connecting to the wiring harness mechanism 222. Multiple first interfaces 2251 are provided, and each of the first interfaces 2251 is located on the left and / or right side of the motor controller 225. The minimum distance Q1 between the first interfaces 2251 and the muffler 212 is set to be greater than or equal to 100 mm, thereby keeping the wiring harness mechanism 222 away from heat sources and improving the safety of the all-terrain vehicle 100.

[0091] As an implementation, the controller assembly 223 is positioned above the motor controller 225 and connected to the motor controller 225 via a wiring harness mechanism 222. The controller assembly 223 includes a plurality of second interfaces 2231, each oriented toward the left and / or right side of the ATV 100. This means that the second interfaces 2231 and the first interfaces 2251 are arranged in the same direction. This facilitates the placement of the wiring harness mechanism 222 between the controller assembly 223 and the motor controller 225, thereby reducing the length of the wiring harness mechanism 222 between the controller assembly 223 and the motor controller 225. This improves the structural compactness of the components and reduces the production cost of the ATV 100. The minimum distance Q2 between the second interfaces 2231 and the muffler 212 is also set to be greater than or equal to 100 mm to keep the wiring harness mechanism 222 away from heat sources, thereby increasing its service life.

[0092] As an implementation, the second interface 2231 is positioned toward 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. Because the wiring harness mechanism 222 has a certain degree of flexibility and can shift from its predetermined fixed position even after being secured, when the wiring harness mechanism 222 is connected to the second interface 2231, at least a portion of the wiring harness mechanism 222 extends toward the muffler 212. This arrangement leaves a sufficient space between the second interface 2231 and the muffler 212 for the wiring harness mechanism 222 to bend, preventing damage to the wiring harness mechanism 222 due to high temperatures in the muffler 212, thereby ensuring the safety of the ATV 100.

[0093] As an implementation, the spacing D3 between the first interface 2251 and the second interface 2231 along the length of the ATV 100 ranges from 64 mm to 96 mm. Specifically, the spacing D3 between the first interface 2251 and the second interface 2231 along the length ranges from 72 mm to 88 mm. More preferably, the spacing D3 between the first interface 2251 and the second interface 2231 along the length is set to 80 mm. Because a wiring harness is connected between the controller assembly 223 and the motor controller 225, this arrangement can shorten the length of the wiring harness mechanism 222, thereby reducing the production cost of the ATV 100.

[0094] As an implementation, when viewed from the height 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 .

[0095] As an implementation, the lowermost end of the walking assembly 13 is substantially located on the reference plane 101. As an implementation, the spacing H2 between the lowermost end of the controller assembly 223 and the reference plane 101 ranges from 770 mm to 940 mm. Specifically, the spacing H2 between the lowermost end of the controller assembly 223 and the reference plane 101 ranges from 810 mm 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. This improves the wading performance of the controller assembly 223 and can also prevent the controller assembly 223 from being arranged too high and interfering with the cargo box assembly 18.

[0096] As an implementation, the controller assembly 223 is fixedly connected to the rear frame 111. A mounting gap Q3 is defined between the controller assembly 223 and the motor controller 225. This mounting gap Q3 increases the ground clearance of the controller assembly 223. The rear frame 111 is also at least partially positioned within the mounting gap Q3. Along the height of the ATV 100, both end faces of the controller assembly 223 are fixedly connected to the rear frame 111, thereby enhancing the stability of the controller assembly 223. As an optional implementation, the mounting gap Q3 ranges from 48 mm to 72 mm. Alternatively, the mounting gap Q3 ranges from 54 mm to 54 mm. More preferably, the mounting gap Q3 is set to 60 mm. This prevents interference between the controller assembly 223 and the cargo box assembly 18 due to an excessively large mounting gap Q3. If the mounting gap Q3 is too small, the rear frame 111 cannot be positioned below the controller assembly 223 for securing. The above arrangement can not only ensure the stability of the controller assembly 223 but also improve the waterproofness of the controller assembly 223 .

[0097] As an implementation, the range extender 142 and the drive motor 141 are arranged across the width of the ATV 100, while the motor controller 225 and the drive motor 141 are arranged along the height of the ATV 100. Specifically, the motor controller 225 is positioned above the drive motor 141. This arrangement evenly distributes the load on the ATV 100 and improves the overall balance of the ATV 100. Furthermore, positioning the motor controller 225 above the drive motor 141 facilitates easy inspection and maintenance of the motor controller 225.

[0098] As an implementation, the transmission assembly 16 further includes a reducer 161 and a transmission shaft 162. The reducer 161 is disposed on a side of the drive motor 141 close to the range extender 142. In this application, the range extender 142 is disposed on the left side of the drive motor 141. The reducer 161 is disposed between the drive motor 141 and the range extender 142, so that the reducer 161 is in transmission connection with the transmission shaft 162. This arrangement reduces the number of connecting components between the reducer 161 and the transmission shaft 162, thereby improving the compactness of the transmission assembly 16.

[0099] As shown in Figure 11, as an implementation, the drive motor 141, motor controller 225, and reducer 16 are integrated to form a drive assembly. The drive assembly is at least partially mounted on the rear frame 111. A reference plane 101 perpendicular to the height of the all-terrain vehicle 100 is defined. The projection of the drive assembly on the reference plane 101 along the height of the all-terrain vehicle 100 is defined as a first projection plane. The projection of the rear frame 111 on the reference plane 101 along the height of the all-terrain vehicle 100 is defined as a second projection plane. The width of the first projection plane extending along the width 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 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 in the range of 0.36 to 0.54. Furthermore, the ratio of the first width W3 to the second width W2 is in the range of 0.4 to 0.5. Preferably, the ratio of the first width W3 to the second width W2 is within a range of 0.43 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 of the all-terrain vehicle 100 will be too large, and the drive assembly will occupy too much space on the frame 11, making it prone to interference with other components on the frame 11. This configuration reduces the space occupied by the drive assembly and improves the compactness of the vehicle.

[0100] As an implementation method, the center of gravity of the drive assembly and the center of gravity of the range extender 142 are respectively arranged on either side of the transmission shaft 162 along the width direction of the ATV 100. This arrangement makes the load distribution in the width direction of the ATV 100 uniform, improving the overall balance of the ATV 100.

[0101] As an implementation, the range extender 142 is at least partially positioned forward of the drive assembly. When viewed along the length of the ATV 100, the drive assembly and the range extender 142 at least partially overlap. Because the range extender 142 and the drive motor 141 are arranged substantially along the width of the ATV 100, this arrangement places the center of gravity of the range extender 142 and the drive assembly closer to the center of the ATV 100. This ensures the ATV 100 maintains a centered center of gravity while preventing interference between the ATV 100 and the components on either side, improving the overall compactness of the vehicle.

[0102] In this embodiment, the ATV 100 further includes a fuel tank 231, which is located to the right of the range extender 142. The fuel tank 231 and the drive assembly are arranged along the length of the ATV 100. This arrangement evenly distributes the load along the length and width of the ATV 100, improving the overall balance of the ATV 100.

[0103] As an implementation, a accommodating space 1111 is formed around the rear frame 111, and the drive assembly is disposed within the accommodating space 1111. A reference plane 101 perpendicular to the height of the ATV 100 is defined. The projection of the accommodating space 1111 onto the reference plane 101 along the height of the ATV 100 is defined as a first projection plane, and the projection of the drive assembly onto the reference plane 101 along the height of the ATV 100 is defined as a second projection plane. The ratio of the area of ​​the first projection plane to the area of ​​the second projection plane is in a range of 4 to 6. Furthermore, the ratio of the area of ​​the first projection plane to the area of ​​the second projection plane is in a range of 4.5 to 5.5. More preferably, the ratio of the area of ​​the first projection plane to the area of ​​the second projection plane can be 5. It should be noted that if the ratio of the area of ​​the first projection plane to the area of ​​the second projection plane is too large, the space occupied by the drive assembly is excessive, which can easily interfere with other components on the frame 11. This arrangement reduces the space occupied by the drive assembly and improves the compactness of the vehicle.

[0104] As an implementation method, the width of the range extender 142 and the drive assembly extending along 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 in the range of 0.53 to 0.8. Furthermore, the ratio of the third width W4 to the second width W2 is in the range of 0.6 to 0.73. More preferably, the ratio of the third width W4 to the second width W2 is in the range of 0.63 to 0.69. If the ratio of the third width W4 to the second width W2 is too large, the width of the range extender 142 and the drive assembly extending along the width direction of the all-terrain vehicle 100 will be too large, so that the space occupied by the range extender 142 and the drive assembly is too large, and the range extender 142 and the drive assembly are likely to interfere with other components on the frame 11. Through the above arrangement, the space occupied by the range extender 142 and the drive assembly is reduced, and the compactness of the entire vehicle is improved.

[0105] As shown in Figures 8 and 14 , as one implementation, the seat assembly 17 includes a rear seat 172 positioned adjacent to the power assembly 14. The rear seat 172 is at least partially mounted on the vehicle frame 11 to provide support for passengers. The rear seat 172 includes a backrest 1721 and a seat cushion 1722 at least partially connected to the backrest 1721. The backrest 1721 includes an upper backrest 1721a, an upper frame 1721c, and a lower backrest 1721b. Specifically, the lower backrest 1721b is connected to the seat cushion 1722, which is detachably connected to the vehicle frame 11. More specifically, the lower backrest 1721b can be integrally formed with the seat cushion 1722, allowing the lower backrest 1721b to be detachably connected to the vehicle frame 11 via the seat cushion 1722. The upper backrest 1721a is rotatably connected to the vehicle frame 11. More specifically, the upper frame 1721c is provided on the upper backrest 1721a, and the upper backrest 1721a is rotatably connected to the vehicle frame 11 via the upper frame 1721c.

[0106] As another implementation, the backrest 1721 may further include a lower frame 1721d fixedly connected to the frame 11, with the lower frame 1721d disposed on the lower backrest 1721b. In this case, the lower backrest 1721b and the seat cushion 1722 are independently provided. Specifically, the lower backrest 1721b and the lower frame 1721d are detachably connected, and the seat cushion 1722 is detachably connected to the frame 11. The upper backrest 1721a and the lower frame 1721d are pivotally connected, meaning that the upper backrest 1721a is not pivotally connected to the frame 11. More specifically, the upper backrest 1721a is pivotally connected to the lower frame 1721d via an upper frame 1721c disposed on the upper backrest 1721a.

[0107] The above-described two configurations facilitate the removal or installation of the lower backrest 1721b and the seat cushion 1722. Furthermore, after the lower backrest 1721b and the seat cushion 1722 are removed, an inspection opening 1721e is formed, allowing components of the ATV 100 located behind the lower backrest 1721b and below the seat cushion 1722 to be inspected through the inspection opening 1721e, thereby reducing the maintenance cost of the ATV 100 and improving the maintainability of the ATV 100. Specifically, the lower backrest 1721b covers the inspection opening 1721e along the length of the ATV 100, allowing the relevant components behind the lower backrest 1721b to be inspected through the inspection opening 1721e. When viewed along the length of the ATV 100, the inspection opening 1721e and the lower backrest 1721b substantially overlap.

[0108] Among them, a first connector 114 and a first clip 115 are provided on the frame 11, and a second connector (not shown) and a second clip (not shown) are provided at the bottom of the seat cushion 1722. The first connector 114 and the second connector are plugged in, and the first clip 115 and the second clip are clipped in to realize a detachable connection between the frame 11 and the seat cushion 1722, thereby improving the disassembly and assembly efficiency of the seat cushion 1722, thereby facilitating the maintenance of components such as the generator controller 224 on the lower side of the seat cushion 1722.

[0109] As an implementation, the rearmost end of the seat cushion 1722 is embedded in the first clamping member 115. Optionally, the first clamping member 115 surrounds and forms a slot into which the seat cushion 1722 can be inserted, and the first clamping member 115 at least partially extends along the width direction of the all-terrain vehicle 100. When the seat cushion 1722 is embedded in the slot, the seat cushion 1722 can rotate around the first clamping member 115.

[0110] As an implementation, first connector 114 is a pin extending substantially in the height direction. The bottom surface of seat cushion 1722 has a socket that engages with first connector 114. Specifically, the second connector can be configured as a socket. When seat cushion 1722 is connected to mid-frame 112, the pin is at least partially disposed within the socket. This configuration improves the ease of removing seat cushion 1722, thereby reducing the difficulty of repairing and replacing generator controller 224.

[0111] Define a transverse plane 103 perpendicular to the length of the ATV 100 (see FIG. 1 ). The projection of the lower backrest 1721b along the length of the ATV 100 onto the transverse plane 103 is defined as a first projection surface. The projection of the backrest 1721 along the length of the ATV 100 onto the transverse plane 103 is defined as a second projection surface. The ratio of the area of ​​the first projection surface to the area of ​​the second projection surface is in a range of 0.29 to 0.56. Specifically, the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface is in a range of 0.36 to 0.49. More specifically, the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface can be 0.43. Through the above-mentioned arrangement, it is possible to avoid the operating space of the inspection opening 1721e formed after the lower backrest 1721b is disassembled being too small, thereby facilitating the inspection of the parts of the all-terrain vehicle 100 located at the rear side of the lower backrest 1721b and at the lower side of the seat cushion 1722, thereby reducing the maintenance cost of the all-terrain vehicle 100; it is also possible to avoid the operating space of the inspection opening 1721e formed after the lower backrest 1721b being too large and occupying additional layout space, thereby improving the space utilization of the all-terrain vehicle 100 and improving the structural compactness of the rear seat 172.

[0112] In this embodiment, the range extender 142 is disposed behind the lower backrest 1721b. When viewed along the length of the ATV 100, the lower backrest 1721b and the range extender 142 at least partially overlap. Furthermore, a transverse plane 103 perpendicular to the length of the ATV 100 is defined. The projection of the lower backrest 1721b along the length of the ATV 100 onto the transverse plane 103 is defined as a first projection, and the projection of the range extender 142 along the length of the ATV 100 onto the transverse plane 103 is defined as a second projection. The first projection and the second projection at least partially overlap. The area of ​​the overlapping portion between the first and second projections is 627 cm. 2 to 941cm 2 Furthermore, the overlapping area of ​​the first projection and the second projection is 705cm 2 to 863cm 2 More preferably, the area of ​​the overlap between the first and second projections is set to 784 cm 2 It should be noted that if the overlapping area of ​​the first and second projections is too small, and the height of the rear seat 172 remains unchanged, the lower backrest 1721b will be removed, resulting in an unrestricted access hatch 1721e, making it difficult to inspect and repair the range extender 142. This arrangement improves the maintenance convenience of the all-terrain vehicle 100.

[0113] In this embodiment, the ATV 100 further includes an air intake assembly 19, which includes an air filter mechanism 191 disposed on the power assembly 14. The air filter mechanism 191 is disposed behind the rear seat 172 and is used to deliver air to the power assembly 14. Specifically, the air filter mechanism 191 is at least partially disposed in front of the range extender 142. The air filter mechanism 191 is also located near the lower backrest 1721b, and the air filter mechanism 191 is connected to the range extender 142. When viewed along the length of the ATV 100, the air filter mechanism 191 and the lower backrest 1721b at least partially overlap. Specifically, the lower frame 1721d is provided with an inspection port 1721e. When viewed along the length of the ATV 100, the inspection port 1721e and the air filter mechanism 191 at least partially overlap. Since the air filter mechanism 191 needs to filter the air entering the range extender 142, dust accumulation can easily cause blockage, thereby affecting the normal operation of the air filter mechanism 191. Therefore, the air filter mechanism 191 needs to be inspected and maintained. With the above arrangement, the air filter mechanism 191 located on the rear side of the lower backrest 1721b can be inspected through the inspection port 1721e, thereby reducing the maintenance cost of the all-terrain vehicle 100.

[0114] As an implementation method, to facilitate assembly and disassembly between lower backrest 1721b and lower frame 1721d, and thereby facilitate inspection and maintenance of range extender 142 and air filter mechanism 191, lower backrest 1721b is provided with a snap-fitting member disposed on the rear end surface of lower backrest 1721b and used to connect to lower frame 1721d. The snap-fitting member and lower frame 1721d can be connected by interlocking or rotation, for example, to facilitate quick assembly and disassembly of lower backrest 1721b from lower frame 1721d. This arrangement facilitates inspection and maintenance of range extender 142 and air filter mechanism 191, improving the maintainability of all-terrain vehicle 100.

[0115] As an implementation method, the height of the upper backrest 1721a extending along the height direction of the all-terrain vehicle 100 is defined as a first height H4, and the height of the lower backrest 1721b extending along the height direction of the all-terrain vehicle 100 is defined as a second height H5. The ratio between the first height H4 and the second height H5 is in the range of 1.8 and less than or equal to 2.6. Furthermore, the ratio between the first height H4 and the second height H5 is in the range of 2 and less than or equal to 2.4. More preferably, the ratio between the first height H4 and the second height H5 can also be 2.2. If the ratio between the first height H4 and the second height H5 is too large, the height of the lower backrest 1721b is too small. After the lower backrest 1721b is disassembled, the space of the inspection port 1721e is small, which is not conducive to maintenance personnel to maintain the air filter mechanism 191 or the range extender 142 through the inspection port 1721e. If the ratio between the first height H4 and the second height H5 is too small, the height of the lower backrest 1721b will be too high, and when the upper backrest 1721a is rotated to the second position, the cargo carrying capacity of the all-terrain vehicle 100 cannot be increased. With the above arrangement, the maintenance convenience of the all-terrain vehicle 100 is improved while ensuring the cargo carrying capacity of the cargo box assembly 18.

[0116] As an implementation, the seat cushion 1722 is disposed below the lower backrest 1721b, and the seat cushion 1722 is configured to be detachably connected to the vehicle frame 11. Optionally, the seat cushion 1722 can be configured to be fixedly connected to the lower backrest 1721b or integrally formed. The all-terrain vehicle 100 also includes a power battery 15 and a generator controller 224. The power battery 15 is connected to the generator controller 224, wherein the generator controller 224 is disposed below the seat cushion 1722 and between the power battery 15 and the range extender 142. When viewed along the height direction of the all-terrain vehicle 100, the seat cushion 1722 and the generator controller 224 at least partially overlap. This configuration allows for inspection and maintenance of the generator controller 224 when the seat cushion 1722 is removed, thereby improving the maintenance convenience of the all-terrain vehicle 100.

[0117] As an implementation method, the lower backrest 1721b and the upper backrest 1721a are arranged to be in surface contact, and form a contact surface that basically extends toward the front and upper part of the all-terrain vehicle 100. A reference plane 101 perpendicular to the height direction of the all-terrain vehicle 100 is defined, and the angle Ω between the contact surface and the reference plane 101 ranges from 0° to 90°. Specifically, the angle Ω between the contact surface and the reference plane 101 ranges from 10° to 80°. Preferably, the angle Ω between the contact surface and the reference plane 101 ranges from 20° to 70°. Through the above arrangement, during the loading and unloading process of the lower backrest 1721b, interference between the lower backrest 1721b and the upper backrest 1721a can be avoided, thereby improving the assemblability of the lower backrest 1721b.

[0118] As shown in Figures 15, 16, and 17, as an implementation, upper backrest 1721a has a first position for seating and a second position for loading cargo. When upper backrest 1721a is in the first position, the rear side of upper backrest 1721a and the rear side of lower backrest 1721b extend in substantially the same direction, allowing upper backrest 1721a and lower backrest 1721b to cooperate in supporting the passenger's back, thereby improving the comfort of rear seat 172. When upper backrest 1721a is in the second position, the rear side of upper backrest 1721a is substantially parallel to the cargo loading surface of cargo box assembly 18. This allows upper backrest 1721a to cooperate with the cargo loading surface of cargo box assembly 18 in the second position, thereby extending the cargo loading length of cargo box assembly 18 and thereby increasing the cargo space of ATV 100. The above arrangement allows the upper backrest 1721a to be used in two different modes, integrating cargo carrying and support functions. This helps increase the functional diversity of the upper backrest 1721a and, in turn, enhances the practicality of the ATV 100. Furthermore, the two different modes of use of the upper backrest 1721a can meet the different usage requirements of the ATV 100 under different working conditions. Thus, without adding additional components, both the seating requirements of the seat assembly 17 and the cargo carrying requirements of the ATV 100 are met. This improves the compactness of the ATV 100 while also increasing the cargo space of the ATV 100 to meet various cargo carrying requirements. Among them, when the upper backrest 1721a is in the second state, the rear side surface of the upper backrest 1721a and the cargo surface of the cargo box assembly 18 are basically at the same height along the height direction of the all-terrain vehicle 100, that is, along the height direction of the all-terrain vehicle 100, the cargo surface of the cargo box assembly 18 is higher than the uppermost end of the lower backrest 1721b, which is conducive to the rear side surface of the upper backrest 1721a and the cargo surface of the cargo box assembly 18 to cooperate to form a cargo space for loading cargo.

[0119] When the upper frame 1721c and the lower frame 1721d are pivotally connected, that is, when the seat cushion 1722 and the lower backrest 1721b are independently provided, the rear seat 172 further includes a pivot shaft 1723, by which the upper frame 1721c and the lower frame 1721d are pivotally connected. The minimum distance D4 between the axis of the pivot shaft 1723 and the cargo loading surface of the cargo box assembly 18 ranges from 66 mm to 125 mm. Specifically, the minimum distance D4 between the axis of the pivot shaft 1723 and the cargo loading surface of the cargo box assembly 18 ranges from 81 mm to 110 mm. More specifically, the minimum distance D4 between the axis of the pivot shaft 1723 and the cargo loading surface of the cargo box assembly 18 can be set to 95.2 mm. This arrangement prevents interference between the upper backrest 1721a and the cargo box assembly 18 during rotation about the pivot shaft 1723, thereby improving the operational stability of the cargo box assembly 18 and the upper backrest 1721a. In this embodiment, the rear seat 172 further includes a connecting plate 1724, which is pivotally connected to the upper frame 1721c or the upper backrest 1721a. A predetermined plane 1724a is defined, and the connecting plate 1724 extends substantially along the predetermined plane 1724a. The connecting plate 1724 has a stowed state and an operational state. When the connecting plate 1724 is in the stowed state, the predetermined plane 1724a and the rear side of the lower backrest 1721b extend in substantially the same direction. When the connecting plate 1724 is in the working state, the preset plane 1724a and the cargo surface of the cargo box assembly 18 are basically parallel. At this time, one end of the connecting plate 1724 is rotatably connected to the upper frame 1721c or the upper backrest 1721a, and the other end of the connecting plate 1724 overlaps the cargo surface of the cargo box assembly 18, so that the connecting plate 1724 can fill the gap between the pivot shaft 1723 and the cargo surface of the cargo box assembly 18 when in the working state, preventing the cargo from falling from the gap between the pivot shaft 1723 and the cargo surface of the cargo box assembly 18, thereby improving the cargo loading safety of the all-terrain vehicle 100.

[0120] As an implementation, the rotation direction of the upper frame 1721c relative to the lower frame 1721d is a first rotation direction, i.e., the rotation direction of the upper backrest 1721a from the first state to the second state is the first rotation direction. The rotation direction of the connecting plate 1724 relative to the upper frame 1721c or the upper backrest 1721a is a second rotation direction, i.e., the rotation direction of the connecting plate 1724 from the storage state to the working state is the second rotation direction. The first rotation direction and the second rotation direction are opposite.

[0121] As an implementation method, when the upper frame 1721c is pivotally connected to the vehicle frame 11, that is, when the seat cushion 1722 and the lower backrest 1721b are connected, the cargo box assembly 18 extends toward the rear seat 172 and forms a cargo extension surface 181. When the upper backrest 1721a is in the second state, the cargo extension surface 181 and the rear side surface of the upper backrest 1721a are substantially aligned, thereby eliminating the structure of the connecting plate 1724, simplifying the structure of the rear seat 172, thereby improving the structural compactness of the rear seat 172 and reducing the production cost of the rear seat 172.

[0122] As shown in Figures 17 and 18 , as one implementation, the rear seat 172 further includes a connecting structure 1725 disposed on the upper backrest 1721a. The upper backrest 1721a includes a preset position for cooperating with the cargo box assembly 18 to carry cargo. When the upper backrest 1721a is in the preset position, i.e., when the upper backrest 1721a is in the second state, the upper backrest 1721a is secured to the vehicle frame 11 via the connecting structure 1725. Specifically, when the upper backrest 1721a rotates to the preset position, the upper backrest 1721a is connected to the vehicle frame 11 via the connecting structure 1725, thereby maintaining the preset position. This prevents the upper backrest 1721a from rotating further due to excessive weight, thereby preventing the cargo on the upper backrest 1721a from detaching from the cargo box assembly 18 and further improving the operational stability of the upper backrest 1721a. The above arrangement can expand the cargo space of the cargo box assembly 18, improve the cargo carrying capacity of the all-terrain vehicle 100, and enhance the stability of the fit between the upper backrest 1721a and the cargo box assembly 18. As an optional implementation, the connecting structure 1725 can be configured as a detachable structure such as a webbing, a hook, or a lock.

[0123] As an implementation, a storage groove 1721f is formed on the rear side of the upper backrest 1721a to accommodate the connecting structure 1725. When the connecting structure 1725 is in a non-operating state, the connecting structure 1725 is at least partially disposed in the storage groove 1721f. This prevents the connecting structure 1725 from interfering with other components of the seat assembly 17 and improves the protection of the connecting structure 1725, thereby increasing the service life of the connecting structure 1725. In addition, this arrangement can also improve the space utilization and structural compactness of the rear backrest 1721.

[0124] As an implementation method, when the upper frame 1721c or the upper backrest 1721a is provided with a connecting plate 1724, when the connecting plate 1724 is in a stored state and the connecting structure 1725 is in a non-working state, the connecting plate 1724 at least partially covers the connecting structure 1725 to keep the connecting structure 1725 fixed.

[0125] In this embodiment, the vehicle frame 11 includes an armrest frame 113 disposed in front of the rear seat 172. When the upper backrest 1721a is in a preset position, the upper backrest 1721a is fixed to the armrest frame 113 via a connecting structure 1725. Specifically, when the upper backrest 1721a is in the preset position, one end of the connecting structure 1725 is connected to the upper backrest 1721a, and the other end of the connecting structure 1725 is provided with a connecting member 1725a. The armrest frame 113 is provided with a fixing member 1131 that cooperates with the connecting member 1725a to fix. This prevents the connecting structure 1725 from sliding on the armrest frame 113, thereby improving the connection stability between the connecting structure 1725 and the armrest frame 113.

[0126] As an implementation method, an anti-slip structure 1132 is also provided on the handrail frame 113. When the fixing member 1131 and the connecting member 1725a are fixed together, the anti-slip structure 1132 at least partially surrounds the connecting member 1725a, thereby preventing the connecting member 1725a from falling off from the fixing member 1131, thereby improving the connection strength between the connecting structure 1725 and the handrail frame 113.

[0127] As an implementation, the rear seats 172 include a single-person rear seat 1726 and a multi-person rear seat 1727, which are distributed across the width of the ATV 100. The single-person rear seat 1726 accommodates a single person, while the multi-person rear seat 1727 accommodates at least two people. Specifically, both the single-person rear seat 1726 and the multi-person rear seat 1727 include the aforementioned backrest 1721 and seat cushion 1722 to accommodate different cargo and passenger needs, thereby increasing the functional versatility of the rear seats 172. More specifically, the width of the multi-person seat 1727 extending across the width of the ATV 100 is defined as a first width W5, and the width of the single-person seat 1726 extending across the width of the ATV 100 is defined as a second width W6, with the first width W5 being greater than the second width W6. Air filter mechanism 191 is positioned behind multi-passenger seat 1727. When viewed along the length of ATV 100, multi-passenger seat 1727 and air filter mechanism 191 at least partially overlap. This arrangement allows for inspection and maintenance of air filter mechanism 191 through multi-passenger seat 1727. Furthermore, because multi-passenger seat 1727 is wider than single seat 1726, it provides greater clearance during inspection and maintenance of air filter mechanism 191, facilitating inspection and maintenance of air filter mechanism 191 and improving the maintainability of ATV 100.

[0128] As shown in FIG19 , as one implementation, the all-terrain vehicle 100 further includes a suspension device 29, which is disposed between the power assembly 14 and the vehicle frame 11. When the power assembly 14 is an engine, the engine is connected to the vehicle frame 11 via the suspension device 29. When the power assembly 14 is a drive motor 141, the drive motor 141 is connected to the vehicle frame 11 via the suspension device 29. When the power assembly 14 is a combination of a range extender 142 and a drive motor 141, the suspension device 29 can be disposed either between the range extender 142 and the vehicle frame 11 or between the drive motor 141 and the vehicle frame 11. Specifically, the suspension device 29 provides support and shock absorption for the power assembly 14, while also limiting the position of the power assembly 14. The suspension device 29 can be used to support the power assembly 14 and reduce the transmission of vibration between the power assembly 14 and the frame 11. At the same time, the suspension device 29 can also limit the movement of the power assembly 14, which is beneficial to improving the stability between the power assembly 14 and the frame 11.

[0129] As an implementation method, the suspension device 29 includes a suspension assembly 291, and at least two or more suspension assemblies 291 constitute the suspension device 29. In the suspension device 29, the axis of the suspension assembly 291 extends along the width direction of the all-terrain vehicle. When the power assembly 14 is a combination of a range extender 142 and a drive motor 141, the minimum distance between the drive motor 141 and the range extender 142 is greater than 0, and the drive motor 141 and the range extender 142 are independently arranged. After the drive motor 141 and the range extender 142 are independently arranged, they can be easily maintained and serviced separately. At the same time, different drive motors 141 and range extenders 142 can be selected for use in combination according to actual needs. The front end of the drive motor 141 is connected to the vehicle frame 11 via at least one suspension assembly 291, and the rear end of the drive motor 141 is connected to the vehicle frame 11 via at least one suspension assembly 291. The front end of the range extender 142 is connected to the vehicle frame 11 via at least one suspension assembly 291, and the rear end of the range extender 142 is connected to the vehicle frame 11 via at least one suspension assembly 291. With this arrangement, when the drive motor 141 and the range extender 142 are started or in operation, the suspension assemblies 291 can reduce vibration transmission between the drive motor 141 and the vehicle frame 11, and between the range extender 142 and the vehicle frame 11, thereby improving the comfort of the all-terrain vehicle 100. Furthermore, the number of suspension assemblies 291 can be increased and adjusted based on different usage scenarios and actual conditions to reduce vibration transmission between the power assembly 14 and the vehicle frame 11 and improve the comfort of the all-terrain vehicle 100. Furthermore, the front end of the drive motor 141 is connected to the vehicle frame 11 via two suspension assemblies 291, and the rear end of the drive assembly 141 291 is connected to the vehicle frame via one suspension assembly 291. The three suspension assemblies 291 on the drive motor 141 can form a stable triangular structure, thereby enhancing the stability of the connection between the drive motor 141 and the vehicle frame 11. Similarly, the front end of the range extender 142 is connected to the vehicle frame 11 via two suspension assemblies 291, and the rear end of the range extender 142 is connected to the vehicle frame 11 via one suspension assembly 291. The three suspension assemblies 291 on the range extender 142 can also form a stable triangular structure, thereby correspondingly enhancing the stability of the connection between the range extender 142 and the vehicle frame 11.

[0130] As shown in FIG20 , as one implementation, suspension assembly 291 includes a base 2911 and a suspension bushing 2912. One end of base 2911 is provided with a connection portion 2911a for connecting to drive motor 141 or range extender 142. The other end of base 2911 is provided with a mounting hole 2911b. Suspension bushing 2912 is disposed in mounting hole 2911b. Suspension bushing 2912 is further connected to frame 11 via fasteners 2913 extending along the width of ATV 100. Specifically, suspension bushing 2912 and mounting hole 2911b are coaxially disposed. The suspension assembly 291 can be fixedly connected to the drive motor 141 or the range extender 142 via the connecting portion 2911a on the base 2911 and fixing devices such as bolts. The suspension assembly 291 can be fixedly connected to the vehicle frame 11 via the mounting holes 2911b on the base 2911, the suspension bushings 2912, and fixing devices such as bolts. That is, the drive motor 141 or the range extender 142 is fixedly connected to the vehicle frame 11 via the base 2911 and the suspension bushings 2912. Through the above arrangement, the connection stability between the vehicle frame 11 and the drive motor 141, and between the vehicle frame 11 and the range extender 142 can be improved.

[0131] As an implementation, suspension assembly 291 further includes crash pads 2913, which are disposed on either side of suspension bushing 2912 or mounting hole 2911b. Crash pads 2913 can buffer forces acting between suspension assembly 291 and frame 11 in the width direction of ATV 100. Crash pads 2913 can be made of a material such as rubber pads, thereby improving the buffering performance of suspension assembly 291 and frame 11, thereby increasing the service life of suspension assembly 291.

[0132] As an implementation, suspension bushing 2912 includes an inner core 2912a, a buffer member 2912b, and an outer tube 2912c. The inner core 2912a, buffer member 2912b, and outer tube 2912c are coaxially arranged, with buffer member 2912b sleeved around the outer side of inner core 2912a, and outer tube 2912c sleeved around the outer side of buffer member 2912b. The inner core 2912a and buffer member 2912b are fixedly connected, while the buffer member 2912b and outer tube 2912c are also fixedly connected. Buffer member 2912b may be made of a rubber block, allowing suspension bushing 2912 to perform both cushioning and support functions. In this embodiment, the inner core 2912a, buffer member 2912b, and outer tube 2912c can be vulcanized after assembly to improve their durability and structural strength, thereby enhancing the structural stability of suspension assembly 291.

[0133] As shown in Figure 21, as an implementation method, a first plane is defined that passes through the axis of outer tube 2912c and is perpendicular to the length of ATV 100. A second plane is also defined that passes through the axis of outer tube 2912c and is perpendicular to the height of ATV 100. The inner side of outer tube 2912c is provided with at least two first soft stops 2912d and at least two second soft stops 2912e. The two first soft stops 2912d are symmetrically distributed about the first plane, and the two second soft stops 2912e are symmetrically distributed about the second plane. The first and second soft stops 2912d, 2912e are evenly positioned between inner core 2912a and outer tube 2912c, and are positioned close to the inner wall of outer tube 2912c. This allows the first and second soft stops 2912d, 2912e to initially cushion strong vibrations generated by the range extender 142 or drive motor 141, thereby enhancing the shock absorption performance of the suspension assembly 291.

[0134] As an implementation, at least two hard stops 2912f are further disposed within the second soft stop portion 2912e (as shown in FIG. 20 ). The two hard stops 2912f are symmetrically distributed about the second plane. When the ATV 100 is traveling on harsh roads, road excitation causes significant vertical vibration of the power assembly 14. The hard stops 2912f further support the drive motor 141 and the range extender 142, thereby improving the stability of the drive motor 141 and the range extender 142, and thus improving the connection stability of the power assembly 14.

[0135] As an implementation, buffer 2912b includes a hard stop 2912g, which abuts the inner wall of outer tube 2912c and the outer wall of inner core 2912a. Hard stop 2912g is used to support outer tube 2912c and inner core 2912a. In the event of significant vibration from drive motor 141 or range extender 142, hard stop 2912g can enhance the support performance of buffer 2912b, preventing significant deformation of outer tube 2912c and inner core 2912a, thereby improving the connection stability between outer tube 2912c and inner core 2912a.

[0136] As an implementation, the dimension of the inner core 2912a along the length of the ATV 100 is greater than or equal to the dimension of the inner core 2912a along the height, and the dimension of the hard stop 2912g along the length of the ATV 100 is less than or equal to the dimension of the hard stop 2912g along the height. The smaller dimension of the inner core 2912a in the height direction allows the buffer 2912b located between the inner core 2912a and the outer tube 2912c to have a larger dimension in the height direction, further enhancing the support and shock absorption performance of the buffer 2912b in the height direction. Specifically, the larger dimension of the hard stop 2912g in the height direction of the buffer 2912b increases the proportion of the hard stop 2912g in the height direction of the buffer 2912b, thereby providing the buffer 2912b with better support and shock absorption performance in the height direction.

[0137] As an implementation, the cushioning element 2912b includes a first linear segment 2912j extending along the length of the ATV 100 and a second linear segment 2912k extending along its height. The first linear segment 2912j is the portion of the cavity structure extending along the length of the ATV 100 within the cushioning element 2912b, while the second linear segment 2912k is the portion of the cavity structure extending along its height. The first and second linear segments 2912j and 2912k reduce vibration transmission, increase the vibration isolation efficiency of the suspension assembly, and enhance the overall comfort of the ATV. In the radial direction of the inner core 2912a, the dimension L8 of the first linear segment 2912j ranges from 2 mm to 4 mm, while the dimension L9 of the second linear segment 2912k ranges from 1.75 mm to 3.25 mm. The linear segment in the buffer 2912b can provide a better shock-absorbing effect, but its ability to provide a supporting effect is relatively poor. Setting the second linear segment 2912k to have a relatively smaller size can increase the distribution ratio of the hard limit portion 2912g in the height direction of the second linear segment 2912k, and can further enable the buffer 2912b to have better supporting performance and shock-absorbing performance in the height direction.

[0138] As shown in Figures 22, 23, and 24, as an implementation, the all-terrain vehicle 100 further includes a suspension assembly 31, through which the front wheel 131 and the rear wheel 132 are connected to the frame 11. The frame 11 includes a rocker support frame 116, which can provide a corresponding connection position for the rocker arm. The suspension assembly 31 includes a suspension rod 311 and a universal joint 312. One end of the suspension rod 311 is connected to the rocker support frame 116, and the other end of the suspension rod 311 is connected to the universal joint 312. The rocker support frame 116 includes a support frame body 1161 and a rod connecting seat 1162. The rod connecting seat 1162 is fixedly connected to the support frame body 1161, and one end of the suspension rod 311 is connected to the rod connecting seat 1162. Specifically, the tie rod connector 1162 includes a first connecting plate 1162a, a second connecting plate 1162b, and a third connecting plate 1162c. A portion of the third connecting plate 1162c is connected to the first connecting plate 1162a, and another portion of the third connecting plate 1162c is connected to the second connecting plate 1162b. A portion of the first connecting plate 1162a is connected to the support frame body 1161, a portion of the second connecting plate 1162b is connected to the support frame body 1161, and a portion of the third connecting plate 1162c is connected to the support frame body 1161. This arrangement improves both the stability of the connections between the first connecting plate 1162a, the second connecting plate 1162b, and the third connecting plate 1162c, and the stability of the connection between the support frame body 1161 and the tie rod connector 1162. Specifically, the connection method in this arrangement can be welding or other connection methods to enhance the deformation resistance of the tie rod connector 1162.

[0139] As one implementation, the first connecting plate 1162a includes a first connecting portion 1162d, the second connecting plate 1162b includes a third connecting portion 1162e, and the third connecting plate 1162c includes a fifth connecting portion 1162f and a sixth connecting portion 1162g. The fifth connecting portion 1162f is connected to the first connecting portion 1162d, and the sixth connecting portion 1162g is connected to the third connecting portion 1162e. The first connecting portion 1162d and the fifth connecting portion 1162f are fixedly connected via welding or other connection methods. This arrangement helps improve the connection stability between the first connecting portion 1162d and the fifth connecting portion 1162f, and between the third connecting portion 1162e and the sixth connecting portion 1162g, thereby improving the connection stability of the pull rod connecting base 1162.

[0140] The first connecting plate 1162a further includes a second connecting portion 1162h, the second connecting plate 1162b further includes a fourth connecting portion 1162j, and the third connecting plate 1162c further includes a seventh connecting portion 1162k. The fifth connecting portion 1162f, the seventh connecting portion 1162k, and the sixth connecting portion 1162g are arranged in a U-shape, meaning that the third connecting plate 1162c generally has a U-shaped structure. In this embodiment, the second connecting portion 1162h is connected to the support frame body 1161, the fourth connecting portion 1162j is connected to the support frame body 1161, and the sixth connecting portion 1162g is connected to the support frame body 1161. Specifically, the second connecting portion 1162h, the fourth connecting portion 1162j, and the seventh connecting portion 1162k generally have a U-shaped structure and are disposed around the surface of the support frame body 1161, which helps improve the connection stability between the support frame body 1161 and the pull rod connecting base 1162.

[0141] As an implementation, the ratio of the area of ​​the second connecting portion 1162h to the area of ​​the first connecting plate 1162a ranges from 0.35 to 0.65, the ratio of the area of ​​the fourth connecting portion 1162j to the area of ​​the second connecting plate 1162b ranges from 0.35 to 0.65, and the ratio of the area of ​​the seventh connecting portion 1162k to the area of ​​the third connecting plate 1162c ranges from 0.2 to 0.4. This arrangement increases the contact area between the first connecting plate 1162a, the second connecting plate 1162b, and the third connecting plate 1162c and the support frame body 1161, thereby improving the fixing strength between the tie rod connecting base 1162 and the support frame body 1161. It also prevents the second connecting portion 1162h, the fourth connecting portion 1162j, and the seventh connecting portion 1162k from being too large, thereby preventing them from encroaching on the space available for the suspension rod 311 in the tie rod connecting base 1162.

[0142] As an implementation, third connecting plate 1162c further includes a first guide portion 1162m connected to fifth connecting portion 1162f and a second guide portion 1162n connected to sixth connecting portion 1162g. First guide portion 1162m is tilted toward first connecting plate 1162a, while second guide portion 1162n is tilted toward second connecting plate 1162b. Specifically, first guide portion 1162m and second guide portion 1162n serve as guides during installation of suspension rod 311, thereby facilitating assembly of suspension rod 311 and rod connector 1162.

[0143] As an implementation, support frame body 1161 includes a left support tube 1161a and a right support tube 1161b. Left support tube 1161a is provided with two vertically spaced tie rod connectors 1162, while right support tube 1161b is provided with two vertically spaced tie rod connectors 1162. Tie rod connectors 1162 are positioned along the height of ATV 100, and the two suspension rods 311 are positioned along the height of ATV 100 without interfering with each other, facilitating maintenance and replacement of suspension rods 311.

[0144] The distance D5 between the two tie rod connectors 1162 on the left support tube 1161a ranges from 70 mm to 130 mm, and the distance D5 between the two tie rod connectors 1162 on the right support tube 1161b ranges from 70 mm to 130 mm. Two independently arranged tie rod connectors 1162 are provided on the left support tube 1161a, and two independently arranged tie rod connectors 1162 are provided on the right support tube 1161b. The independent arrangement of the tie rod connectors 1162 can reduce the difficulty of assembly. At the same time, it can also avoid the suspension rod 311 and the tie rod connector 1162 from interfering with each other due to the distance between the tie rod connectors 1162 being too close, which is beneficial to improving the working stability of the suspension rod 311. Furthermore, the distance D5 between the two tie rod connection seats 1162 on the left support tube 1161a ranges from 80 mm to 120 mm, and the distance D5 between the two tie rod connection seats 1162 on the right support tube 1161b ranges from 80 mm to 120 mm. Furthermore, the distance D5 between the two tie rod connection seats 1162 on the left support tube 1161a ranges from 80 mm to 120 mm, and the distance D5 between the two tie rod connection seats 1162 on the right support tube 1161b ranges from 80 mm to 120 mm.

[0145] As one implementation, first connecting plate 1162a includes a first reinforcement portion 1162p, which is located on a side of first connecting plate 1162a away from third connecting plate 1162c. Second connecting plate 1162b includes a second reinforcement portion 1162q, which is located on a side of second connecting plate 1162b away from third connecting plate 1162c. First reinforcement portion 1162p and second reinforcement portion 1162q can increase the strength of first connecting plate 1162a and second connecting plate 1162b, thereby improving the overall strength of tie rod connector 1162. Specifically, first reinforcement portion 1162p and second reinforcement portion 1162q can be reinforcing ribs.

[0146] As an implementation, one end of the first connecting plate 1162a is connected to one end of the second connecting plate 1162b. Specifically, the first connecting plate 1162a and the second connecting plate 1162b can be provided separately, fixedly connected, or integrated. This not only helps to improve the connection strength between the first connecting plate 1162a and the second connecting plate 1162b, but also helps to improve the connection strength between the pull rod connecting base 1162 and the support frame body 1161.

[0147] As an implementation, the thickness of third connecting plate 1162c is less than or equal to the thickness of first connecting plate 1162a or second connecting plate 1162b. Third connecting plate 1162c is generally U-shaped and forms a connection space for suspension rod 311. A portion of first connecting plate 1162a and a portion of second connecting plate 1162b are connected to both sides of third connecting plate 1162c. A thinner third connecting plate 1162c avoids encroaching on the connection space of suspension rod 311, thereby improving installation convenience of suspension rod 311.

[0148] As shown in Figures 25 and 26 , as one implementation, the vehicle frame 11 includes a front frame 117 disposed at the front of the vehicle frame 11. The front frame 117 defines a storage space. The air conditioning assembly 24 is connected to the front frame 117 and is at least partially disposed within the storage space. The air conditioning assembly 24 includes a compression mechanism 241, an air conditioning main unit 242, a heat exchange mechanism 243, and a condensing mechanism 244. The condensing mechanism 244 is disposed in front of the air conditioning main unit 242. The compression mechanism 241 is at least partially disposed between the condensing mechanism 244 and the air conditioning main unit 242. The heat exchange mechanism 243 is disposed on one of two sides of the compression mechanism 241 along the width of the all-terrain vehicle 100. During operation, air liquefies into water upon contact with the heat exchange mechanism 243. This arrangement prevents water from dripping onto the compression mechanism 241, thereby preventing damage to the compression mechanism 241 or potential safety hazards caused by water, thereby improving the safety of the air conditioning assembly 24. Furthermore, the above arrangement facilitates the piping arrangement of the air conditioning assembly 24, thereby reducing the length of the piping of the air conditioning assembly 24 and lowering the cost of the air conditioning assembly 24. Specifically, a positioning surface 104 perpendicular to the height direction of the all-terrain vehicle 100 is defined, with the lowest end of the compression mechanism 241 located on the positioning surface 104, and the air conditioning main unit 242, the heat exchange mechanism 243, and the condensing mechanism 244 all located on the upper side of the positioning surface 104. This positions the compression mechanism 241 at the lowest end of the air conditioning assembly 24, facilitating the return of lubricating oil in the piping of the air conditioning assembly 24, thereby lubricating the various components of the air conditioning assembly 24 and improving the lubrication effect of the various components of the air conditioning assembly 24, thereby increasing the service life of the air conditioning assembly 24 and improving the operating stability of the air conditioning assembly 24, thereby improving the performance of the air conditioning assembly 24.

[0149] In this embodiment, the air conditioning assembly 24 also includes an air conditioning control mechanism 245, which is mounted on the air conditioning main unit 242. This allows the air conditioning control mechanism 245 to be integrated with the air conditioning main unit 242, thereby improving the space utilization of the air conditioning assembly 24 and enhancing the structural compactness of the air conditioning assembly 24. Specifically, one end of the air conditioning control mechanism 245 is fixedly connected to the air conditioning main unit 242, while the other end of the air conditioning control mechanism 245 engages with the air conditioning main unit 242, facilitating installation and removal of the air conditioning control mechanism 245 and improving its assembly efficiency. Furthermore, the air conditioning assembly 24 also includes an adjustment mechanism 246. The ATV 100 also includes a cockpit 26 located between the front wheels 131 and the rear wheels 132. The adjustment mechanism 246 is located on the front side of the cockpit 26, allowing the user to adjust the temperature of the air conditioning assembly 24 through the adjustment mechanism 246, thereby improving the comfort and human-machine interaction of the ATV 100.

[0150] As an implementation, the ATV 100 further includes a cooling assembly 25, which includes a heat dissipation mechanism 251 disposed on the front side of the vehicle frame 11. The condensing mechanism 244 is at least partially disposed on the heat dissipation mechanism 251. This arrangement allows the condensing mechanism 244 to be integrated with the heat dissipation mechanism 251, thereby improving the structural compactness and space utilization of the air conditioning assembly 24 and the cooling assembly 25. Furthermore, this arrangement allows the heat dissipation mechanism 251 to dissipate heat from the condensing mechanism 244, thereby improving the cooling efficiency of the condensing mechanism 244 and further enhancing the operating efficiency of the air conditioning assembly 24.

[0151] In this embodiment, the front frame 117 includes a fixing bracket 1171 and a connecting bracket 1172. The fixing bracket 1171 is disposed between the condensing mechanism 244 and the compression mechanism 241, while the connecting bracket 1172 is located at the frontmost side of the front frame 117. The fixing bracket 1171 is connected to the connecting bracket 1172, which is disposed in front of the fixing bracket 1171. The compression mechanism 241 is disposed on the fixing bracket 1171, and the heat dissipation mechanism 251 is disposed on the fixing bracket 1171. This arrangement improves the connection stability of the compression mechanism 241, the heat dissipation mechanism 251, and the condensing mechanism 244, thereby preventing displacement during movement of the all-terrain vehicle 100 and thereby preventing the air conditioning assembly 24 from operating normally. This improves the operational stability of the air conditioning assembly 24.

[0152] As shown in FIG27 , as an implementation method, the cooling assembly 25 further includes a battery cooling line 252 and a front water tank 253. Both the battery cooling line 252 and the front water tank 253 are disposed on the front frame 117. The front water tank 253, the power battery 15, and the air conditioning main unit 242 are connected via the battery cooling line 252. With this arrangement, the battery cooling line 252 can be disposed close to the power battery 15, thereby reducing the length of the battery cooling line 252 and lowering the cost of the line. Furthermore, the battery cooling line 252 can be cooled by the air conditioning main unit 242, thereby improving the operating efficiency of the battery cooling line 252 and facilitating improved energy efficiency of the all-terrain vehicle 100.

[0153] As an implementation, the cooling assembly 25 further includes a first cooling line 254 and a first water tank 255. The first water tank 255, the heat dissipation mechanism 251, and the range extender 142 are connected via the first cooling line 254. With this arrangement, the first cooling line 254 can be used to cool the range extender 142. The first water tank 255, the first cooling line 254, the range extender 142, and the heat dissipation mechanism 251 form an independent cooling circuit, so that the cooling of the range extender 142 is not affected by other cooling circuits, thereby improving the cooling efficiency of the range extender 142.

[0154] In this embodiment, the cooling assembly 25 further includes a second cooling pipe 256 and a second water tank 257. The second water tank 257, the heat dissipation mechanism 251, and the drive motor 141 are connected via the second cooling pipe 256. With this arrangement, the second cooling pipe 256 can be used to cool the drive motor 141. The second water tank 257, the second cooling pipe 256, the heat dissipation mechanism 251, and the drive motor 141 form an independent cooling circuit, so that the cooling of the drive motor 141 is not affected by other cooling circuits, thereby improving the cooling efficiency of the drive motor 141.

[0155] In this embodiment, the first water tank 255 and the second water tank 257 are both arranged on the rear side of the frame 11. The first water tank 255 and the second water tank 257 are distributed along the width direction of the all-terrain vehicle 100. The first water tank 255 is arranged on the side close to the range extender 142, and the second water tank 257 is arranged on the side close to the drive motor 141, so that the arrangement of the first cooling pipeline 254 and the arrangement of the second cooling pipeline 256 will not interfere with each other.

[0156] Furthermore, along the width of the ATV 100, the first cooling line 254 and the second cooling line 256 are at least partially disposed on either side of the power battery 15. Taking the example of a case where the range extender 142 is disposed on the left side of the ATV 100 and the drive motor 141 is disposed on the right side of the ATV 100, the first cooling line 254 at least partially extends along the left side of the frame 11 in the longitudinal direction of the ATV 100, and the second cooling line 256 at least partially extends along the right side of the frame 11 in the longitudinal direction of the ATV 100. This prevents interference between the first cooling line 254 and the second cooling line 256. Therefore, if any cooling line fails, the normal operation of the other cooling lines will not be affected. This facilitates modularization of the cooling assembly 25 and reduces maintenance costs of the cooling assembly 25.

[0157] As shown in FIG. 28 , as an embodiment, the air conditioning assembly 24 includes an air outlet mechanism 247 connected to the air conditioning main unit 242 , and the air outlet mechanism 247 can deliver the cold air or warm air generated by the air conditioning main unit 242 into the all-terrain vehicle 100 .

[0158] The air outlet mechanism 247 includes an air outlet body 2471 and an air guide cover 2472. The air outlet body 2471 is in the shape of a circular tube, and the air guide cover 2472 is detachably connected to one end of the air outlet body 2471. As shown in Figure 29, the side walls of the air outlet body 2471 enclose a storage space 2471a that can be used to store items. The ratio of the length L10 of the storage space 2471a to the diameter R of the storage space 2471a ranges from 2.2 to 4.3. In this embodiment, the storage space 2471a is configured so that the length L10 is much greater than the diameter R, so that the storage space 2471a has a large storage depth, which can facilitate the placement of beverage bottles or beverage cans in the storage space 2471a. The above configuration can utilize the storage space in the air outlet body 2471 as a space for chilling or heating beverages, and the cold air or warm air output from the air outlet mechanism 247 can be used to cool or heat the beverages. Furthermore, the ratio of the length L10 of the accommodation space 2471a to the diameter R of the accommodation space 2471a ranges from 2.6 to 3.9. Furthermore, the ratio of the length L10 of the accommodation space 2471a to the diameter R of the accommodation space 2471a ranges from 2.9 to 3.6.

[0159] Define a reference plane 101 perpendicular to the height direction of the ATV 100. The angle δ between the axis of the air outlet body 2471 and the reference plane 101 ranges from 8.5° to 19.5°. The air outlet body 2471 is intended to hold beverage bottles or cans. If the angle δ between the axis of the air outlet body 2471 and the reference plane 101 is too small, the bottle or can can easily escape from the air outlet body 2471 during travel, compromising the safety of the ATV 100. If the angle δ between the axis of the air outlet body 2471 and the reference plane 101 is too large, the airflow direction of the air outlet mechanism 247 is affected, potentially preventing the timely delivery of cool or warm air to the rider. Furthermore, the angle δ between the axis of the air outlet body 2471 and the reference plane 101 ranges from 9.5° to 18°. Furthermore, the angle δ between the axis of the air outlet body 2471 and the reference plane 101 ranges from 11° to 16°.

[0160] On the axis of the air outlet body 2471, the length L10 of the accommodating space 2471a ranges from 140mm to 260mm. The length of the accommodating space 2471a within the above range can meet the requirements of placing most beverage bottles and beverage cans on the market in the accommodating space 2471a, while ensuring that at least 2 / 3 of the beverage bottles or beverage cans are located in the accommodating space 2471a, and can ensure the stability of the beverage bottles and beverage cans placed in the accommodating space 2471a. At the same time, it can also avoid the unreasonable occupation of the vehicle interior space when the length L10 of the accommodating space 2471a is too long. Furthermore, the length L10 of the accommodating space 2471a ranges from 160mm to 240mm. Furthermore, the length L10 of the accommodating space 2471a ranges from 180mm to 220mm.

[0161] In a direction perpendicular to the axis of the air outlet body 2471, the diameter R of the accommodating space 2471a ranges from 40 mm to 90 mm. Within this range, the diameter R of the accommodating space 2471a can accommodate most beverage bottles and cans on the market. This also prevents an excessively large diameter R of the accommodating space 2471a from unduly occupying the vehicle's interior space. Furthermore, the diameter R of the accommodating space 2471a ranges from 50 mm to 80 mm. Furthermore, the diameter R of the accommodating space 2471a ranges from 60 mm to 70 mm.

[0162] As shown in FIG30 , the air outlet mechanism 247 includes a hollow partition 2473, which is disposed at one end of the air outlet body 2471 away from the air guide cover 2472, that is, at the bottom of the air outlet body 2471. The hollow partition 2473 prevents obstruction of the air outlet mechanism 247 from delivering cold and warm air, and also provides support for beverages placed in the air outlet body 2471. The hollow partition 2473 includes a hollow portion 2473a, which defines a projection plane perpendicular to the axis of the air outlet body 2471. The hollow partition 2473 has a partition projection on the projection plane, and the hollow portion 2473a has a projection of the hollow portion 2473a on the projection plane. The ratio of the area of ​​the hollow projection to the area of ​​the partition projection ranges from 0.05 to 0.35. The hollow partition 2473 needs to meet the ventilation requirements and avoid a reduction in ventilation volume, while also providing support for the beverage placed in the air outlet body 2471. When the hollow portion 2473a is too large, the carrying capacity of the hollow partition 2473 is reduced, and there may be a problem that the hollow partition 2473 is not sufficient to carry the beverage. Similarly, when the hollow portion 2473a is too small, the hollow partition 2473 will affect the ventilation volume of the air outlet body 2471 and reduce the cooling or heating effect. Furthermore, the ratio of the area of ​​the hollow projection to the area of ​​the partition projection ranges from 0.05 to 0.25. Furthermore, the ratio of the area of ​​the hollow projection to the area of ​​the partition projection ranges from 0.05 to 0.15.

[0163] The air guide cover 2472 is connected to the air outlet body 2471 by screwing, snapping, or plugging. The connection between the air guide cover 2472 and the air outlet body in this manner can improve the convenience of installing and removing the air guide cover 2472, making it easy to quickly install the air guide cover 2472 to ensure normal use of the air conditioning assembly 24, and also easy to quickly remove the air guide cover 2472 to allow beverage bottles or cans to be placed in the air outlet body 2471 for cooling or heating.

[0164] The air outlet mechanism 247 also includes an anti-slip member 2474, which is disposed on the inner wall of the air outlet body 2471. The anti-slip member 2474 disposed on the inner wall of the air outlet body 2471 can further improve the stability of beverage bottles and cans placed in the air outlet body 2471. Specifically, the anti-slip member 2474 can be at least one of an anti-slip pad or an anti-slip strip.

[0165] As shown in Figure 31 , as one implementation, the vehicle body panel 12 includes a composite panel 122 made of heat- and / or sound-insulating material. Composite panel 122 includes a first composite member 1221 positioned between the seat assembly 17 and the powertrain assembly 14. Alternatively, first composite member 1221 is positioned at least partially around the range extender 142 and / or the drive motor 141.

[0166] In this embodiment, a transverse plane 103 perpendicular to the length of the ATV 100 is defined. The projection of the first composite member 1221 along the length of the ATV 100 onto the transverse plane 103 is defined as a first projection surface. The projection of the body panel 12 along the length of the ATV 100 onto the transverse plane 103 is defined as a second projection surface. The ratio of the area of ​​the first projection surface to the area of ​​the second projection surface is in a range of 0.16 to 0.31. Specifically, the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface is in a range of 0.19 to 0.27. More specifically, the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface can be 0.23. Through the above-mentioned arrangement, it is possible to prevent the area of ​​the first projection surface from being too large, which is not conducive to the arrangement of the frame 11 at the first composite part 1221, thereby avoiding insufficient strength of the frame 11 and reducing the overall structural strength of the all-terrain vehicle 100; it is also possible to prevent the area of ​​the first projection surface from being too large, which may cause interference between the first composite part 1221 and other components of the all-terrain vehicle 100, thereby facilitating improvement of the space utilization rate of the all-terrain vehicle 100; it is also possible to prevent the area of ​​the first projection surface from being too small, which may reduce the heat insulation and sound insulation effect of the first composite part 1221 on the power assembly 14, thereby meeting the arrangement requirements of the frame 11 and the structural strength requirements of the all-terrain vehicle 100, and the heat generated by the power assembly 14 can be isolated by the first composite part 1221, reducing the noise generated when the power assembly 14 is working, and at the same time reducing the arrangement of sound insulation cotton, heat insulation parts, etc., thereby reducing the weight of additional components of the all-terrain vehicle 100, thereby facilitating lightweighting of the all-terrain vehicle 100. In addition, the first composite member 1221 can also reduce the vibration transmitted from the power assembly 14 to the seat assembly 17 , thereby improving the riding comfort of the all-terrain vehicle 100 .

[0167] As an implementation, the ATV 100 further includes a door 27 (see FIG. 1 ), and the composite panel 122 further includes a second composite member 1222 disposed on the door 27. A longitudinal plane 102 perpendicular to the width of the ATV 100 is defined, with the projection of the second composite member 1222 onto the longitudinal plane 102 along the width of the ATV 100 being a third projection plane, and the projection of the door 27 onto the longitudinal plane 102 along the width of the ATV 100 being a fourth projection plane. The ratio of the area of ​​the third projection plane to the area of ​​the fourth projection plane ranges from 0.19 to 0.37. Specifically, the ratio of the area of ​​the third projection plane to the area of ​​the fourth projection plane ranges from 0.24 to 0.33. More specifically, the ratio of the area of ​​the third projection plane to the area of ​​the fourth projection plane can be 0.28. Through the above-mentioned arrangement, it is possible to prevent the area of ​​the third projection surface from being too large and affecting the overall structural strength of the vehicle door 27, and to prevent the area of ​​the third projection surface from being too small and reducing the heat insulation and sound insulation effects of the second composite component 1222 on the cockpit 26 (refer to Figure 2). In this way, the second composite component 1222 can isolate the heat from the outside of the all-terrain vehicle 100 and reduce the noise transmitted from the outside of the all-terrain vehicle 100 to the inside of the cockpit 26 while meeting the structural strength requirements of the vehicle door 27. At the same time, it can also reduce the weight of the vehicle door 27, which is conducive to the lightweighting of the all-terrain vehicle 100.

[0168] As an implementation, the body panel 12 further includes a control panel 123 located in front of the seat assembly 17. The control panel 123 is configured to include operating buttons or panels for controlling at least a portion of the electrical components 22. The composite panel 122 further includes a third composite component 1223 disposed on the control panel 123. The projection of the third composite component 1223 onto the transverse plane 103 along the length of the ATV 100 is a fifth projection surface. The projection of the control panel 123 onto the transverse plane 103 along the length of the ATV 100 is a sixth projection surface. The ratio of the area of ​​the fifth projection surface to the area of ​​the sixth projection surface is in a range of 0.27 to 0.51. Specifically, the ratio of the area of ​​the fifth projection surface to the area of ​​the sixth projection surface is in a range of 0.32 to 0.45. More specifically, the ratio of the area of ​​the fifth projection surface to the area of ​​the sixth projection surface can be 0.39. Through the above-mentioned arrangement, it is possible to prevent the area of ​​the fifth projection surface from being too large and affecting the overall structural strength of the control panel 123, and to prevent the area of ​​the fifth projection surface from being too small and reducing the heat insulation and sound insulation effects of the third composite component 1223 on the control panel. In this way, the third composite component 1223 can isolate the heat and noise transmitted from the front side of the all-terrain vehicle 100 to the cockpit 26 while meeting the structural strength requirements of the control panel 123, and at the same time reduce the weight of the control panel 123, which is conducive to the lightweighting of the all-terrain vehicle 100.

[0169] As an implementation, the composite panel 122 further includes a fourth composite member 1224 disposed on the cargo box assembly 18. A reference plane 101 perpendicular to the height direction of the ATV 100 is defined, with the projection of the fourth composite member 1224 on the reference plane 101 along the height direction being a seventh projection plane, and the projection of the cargo box assembly 18 on the reference plane 101 along the height direction being an eighth projection plane. The ratio of the area of ​​the seventh projection plane to the area of ​​the eighth projection plane ranges from 0.48 to 0.91. Specifically, the ratio of the area of ​​the seventh projection plane to the area of ​​the eighth projection plane ranges from 0.59 to 0.81. More specifically, the ratio of the area of ​​the seventh projection plane to the area of ​​the eighth projection plane can be 0.69. This arrangement prevents the seventh projection surface from being too large, thereby reducing the overall structural strength of the cargo box assembly 18, and also prevents the seventh projection surface from being too small, thereby reducing the heat insulation, sound insulation, and vibration reduction effects of the fourth composite member 1224 on the cargo box assembly 18. As a result, while still meeting the structural strength requirements of the cargo box assembly 18, the fourth composite member 1224 can improve the sound insulation and heat insulation effects of the cargo box assembly 18 and reduce the weight of the cargo box assembly 18, thereby contributing to the lightweighting of the all-terrain vehicle 100. Furthermore, since the power assembly 14 is disposed on the underside of the cargo box assembly 18, the fourth composite member 1224 can also reduce the adverse effects of noise and vibration generated by the power assembly 14 on the cargo box assembly 18.

[0170] As an implementation, the vehicle body panel 12 includes a guard plate structure 121 disposed below the power battery 15 (see FIG4 ). The composite panel 122 also includes a fifth composite member 1225 disposed on the guard plate structure 121 and a sixth composite member 1226 disposed above the power battery 15. A reference plane 101 perpendicular to the height of the all-terrain vehicle 100 is defined. The projections of the fifth and sixth composite members 1225, 1226 on the reference plane 101 along the height direction are referred to as the ninth projection plane. The projections of the power battery 15 on the reference plane 101 along the height direction are referred to as the tenth projection plane. The ratio of the area of ​​the ninth projection plane to the area of ​​the tenth projection plane ranges from 0.66 to 1.23. Specifically, the ratio of the area of ​​the ninth projection plane to the area of ​​the tenth projection plane ranges from 0.8 to 1.09. More specifically, the ratio of the area of ​​the ninth projection plane to the area of ​​the tenth projection plane can be 0.94. This arrangement prevents the ninth projection surface from being too large, thereby reducing the space available for arranging the power battery 15 and surrounding components, and prevents the ninth projection surface from being too small, thereby reducing the thermal insulation effect of the fifth and sixth composite members 1225 and 1226 on the power battery 15. Consequently, the fifth and sixth composite members 1225 and 1226 improve the thermal insulation capability of the power battery 15 and enhance the shock absorption and cushioning effect on the power battery 15 while still meeting the requirements for arranging the power battery 15 and surrounding components. Furthermore, the sixth composite member 1226 serves as a housing for the power battery 15, thereby maintaining stable operation of the power battery 15, thereby improving the operating efficiency and conversion efficiency of the power battery 15 and further enhancing the endurance of the all-terrain vehicle 100.

[0171] As an implementation method, the composite panel 122 is configured as a plate-like structure with a honeycomb structure, so that the composite panel 122 can absorb noise and vibration while isolating heat, thereby achieving the heat insulation and sound insulation functions of the composite panel 122.

[0172] In this embodiment, the composite panel 122 is configured as a double-layer structure, thereby improving the thermal and sound insulation effects of the composite panel 122. Specifically, the composite panel 122 is disposed at least partially around the ATV 100, thereby isolating the heat from both the interior and exterior of the ATV 100, thereby improving the cooling and heating effects of the air conditioning assembly 24 and further enhancing the comfort of the ATV 100.
