The engine 111 includes at least one cylinder 1111 and a cylinder head 1112 located at one end of the cylinder 1111. The cylinder 1111 contains a combustion chamber and a piston assembly, and the combustion chamber is connected to the intake system 25. The engine 111 is mounted on the frame 12. In this embodiment, the transmission assembly 14 is a CVT transmission. It is understood that the transmission assembly 14 can also be other transmissions such as an AT automatic transmission, a DCT dual-clutch transmission, etc.

[0037] like Figure 4As shown, the vehicle frame 12 is provided as a metal frame, including a vehicle frame body 121 and a front support frame 122, the vehicle frame body 121 including a first main beam 1211, a second main beam 1212, a third main beam 1213, a fourth main beam 1214, a fifth main beam 1215, a sixth main beam 1216, a seventh main beam 1217, an eighth main beam 1218 and a ninth main beam 1219, the vehicle frame body 121 being capable of being made by welding, the front support frame 122 being provided at the front side of the vehicle frame body 121 in the front-rear direction, the front support frame 122 serving as an extension of the vehicle frame 12 and being capable of extending the length of the vehicle frame 12 as a whole, so that the vehicle frame 12 is capable of being equipped with more devices.

[0038] As Figure 5 and Figure 6As shown, the vehicle body cover 23 comprises a first mudguard 231. The first mudguard 231 is located at the front of the all-terrain vehicle 100, the first mudguard 231 is installed on the vehicle frame 12, and the first mudguard 231 is used to prevent the first walking wheel 261 from throwing mud into the inside of the all-terrain vehicle 100 or the user's body. The all-terrain vehicle 100 has a symmetry plane 303 perpendicular to the left-right direction, and the all-terrain vehicle 100 is arranged substantially symmetrically about the symmetry plane 303. The first mudguard 231 is a structure substantially symmetric about the symmetry plane 303, and the first walking wheel 261 on the right side of the all-terrain vehicle 100 is a right walking wheel. The first mudguard 231 is provided with a flow guide hole 2314, a flow guide plate 2315, a windward surface 2311 and an air inlet surface 2312. The flow guide hole 2314 comprises a first flow guide hole 2314a and a second flow guide hole 2314b. The flow guide plate 2315 comprises a first flow guide plate 2315a and a second flow guide plate 2315b. The position of the right walking wheel of the all-terrain vehicle 100 is described. In the front-rear direction of the all-terrain vehicle 100, the windward surface 2311 is arranged close to the rear side of the right walking wheel, and the windward surface 2311 is used to meet the ambient air flowing into the all-terrain vehicle 100 from the front side of the all-terrain vehicle 100 during driving. The air inlet surface 2312 is connected to the windward surface 2311, and the air inlet surface 2312 is arranged on the side of the right walking wheel facing the vehicle interior. The first flow guide hole 2314a is arranged at the connection between the air inlet surface 2312 and the windward surface 2311, that is, the first flow guide hole 2314a is at least partially arranged on the air inlet surface 2312, and the first flow guide hole 2314a is at least partially arranged on the windward surface 2311. The first flow guide hole 2314a is used to guide the ambient air flowing into the windward surface 2311 into the interior of the all-terrain vehicle 100, thereby reducing the internal temperature of the all-terrain vehicle 100. During driving of the all-terrain vehicle 100, the ambient air continuously gathers on the windward surface 2311, causing the air pressure on the windward surface 2311 to gradually increase, while the air pressure of the air inlet surface 2312 is low, thereby forming a pressure difference, and the ambient air flows from the place with high air pressure to the place with low air pressure, that is, the ambient air flows from the windward surface 2311 to the air inlet surface 2312, and is guided into the vehicle interior through the first flow guide hole 2314a. By reasonably arranging the position of the first flow guide hole 2314a, the amount of air passing through the vehicle interior can be increased by using the ambient air driven by the vehicle during driving, thereby significantly reducing the temperature inside the vehicle interior and improving the riding comfort. Specifically, the vehicle body cover 23 forms an accommodation space 23a (refer to Figure 1 ). The first flow guide hole 2314a communicates with the accommodation space 23a, so that air enters the accommodation space 23a, thereby improving the heat dissipation effect of the vehicle body cover 23, and further improving the heat dissipation effect and service life inside the all-terrain vehicle 100, and improving the comfort of the all-terrain vehicle 100.

[0039] Specifically, the first mudguard 231 further comprises a plurality of first flow guide plates 2315a. The plurality of first flow guide plates 2315a are arranged in the first flow guide hole 2314a, and the plurality of first flow guide plates 2315a divide the first flow guide hole 2314a into a plurality of air holes. During the driving of the all-terrain vehicle 100, the first flow guide plate 2315a can increase the air intake of the first flow guide hole 2314a, thereby increasing the amount of air introduced into the all-terrain vehicle 100, and thereby improving the heat dissipation effect and service life of the all-terrain vehicle 100. In addition, through the above arrangement, the first flow guide plate 2315a can block mud and water and the like from entering the first flow guide hole 2314a during the driving of the all-terrain vehicle 100, preventing the first flow guide hole 2314a from being blocked and affecting the air intake efficiency of the first flow guide hole 2314a, thereby improving the air intake efficiency of the first flow guide hole 2314a, and thereby improving the heat dissipation effect and service life of the all-terrain vehicle 100.

[0040] In the present embodiment, the all-terrain vehicle 100 further comprises a second flow guide hole 2314b and a second flow guide plate 2315b. The second flow guide hole 2314b and the second flow guide plate 2315b are both arranged on the left side of the all-terrain vehicle 100. Specifically, the first flow guide hole 2314a and the second flow guide hole 2314b are substantially symmetrically arranged about the symmetry plane 303, and the first flow guide plate 2315a and the second flow guide plate 2315b are substantially symmetrically arranged about the symmetry plane 303. A plurality of second flow guide plates 2315b are arranged in the second flow guide hole 2314b, and the plurality of second flow guide plates 2315b divide the second flow guide hole 2317 into a plurality of air holes. During the driving of the all-terrain vehicle 100, the second flow guide plate 2315b can increase the air intake of the second flow guide hole 2314b, thereby increasing the amount of air introduced into the all-terrain vehicle 100, and thereby improving the heat dissipation effect and service life of the all-terrain vehicle 100. Specifically, the second flow guide hole 2314b communicates with the accommodation space 23a, so that air enters the accommodation space 23a, thereby improving the heat dissipation effect of the vehicle body cover 23, and thereby improving the heat dissipation effect and service life of the all-terrain vehicle 100, and improving the comfort of the all-terrain vehicle 100.

[0041] In addition, through the above arrangement, during the driving of the all-terrain vehicle 100, the second flow guide plate 2315b can block mud and water and the like from entering the second flow guide hole 2314b, prevent the second flow guide hole 2314b from being blocked to affect the air intake efficiency of the second flow guide hole 2314b, thereby improving the air intake efficiency of the second flow guide hole 2314b, and further improving the heat dissipation effect and service life of the all-terrain vehicle 100. In addition, the left side of the all-terrain vehicle 100 is provided with a windward surface 2311 and an air inlet surface 2312. The windward surface 2311 on the left side and the windward surface 2311 on the right side are substantially symmetrically arranged about the symmetry plane 303, and the air inlet surface 2312 on the left side and the air inlet surface 2312 on the right side are substantially symmetrically arranged about the symmetry plane 303. Specifically, the effect and connection relationship of the windward surface 2311 on the left side and the windward surface 2311 on the right side are substantially the same, and the effect and connection relationship of the air inlet surface 2312 on the left side and the air inlet surface 2312 on the right side are substantially the same.

[0042] As an implementation manner, in a third projection plane 306 perpendicular to the front-rear direction of the all-terrain vehicle 100, the first flow guide hole 2314a is projected on the third projection plane 306 as a first projection plane along the front-rear direction of the all-terrain vehicle 100, and the second flow guide hole 2314b is projected on the third projection plane 306 as a second projection plane along the front-rear direction of the all-terrain vehicle 100. The area of the first projection plane is greater than or equal to 5800mm 2 and less than or equal to 9000mm 2 . The area of the second projection plane is greater than or equal to 5800mm 2 and less than or equal to 9000mm 2 . Through the above arrangement, the amount of air introduced into the interior of the all-terrain vehicle 100 can be increased, and the heat dissipation effect and service life of the all-terrain vehicle 100 can be improved. Specifically, the first flow guide hole 2314a and the second flow guide hole 2314b are both communicated with the accommodation space 23a, so that air enters the accommodation space 23a, thereby improving the heat dissipation effect of the vehicle body cover 23, further improving the heat dissipation effect and service life of the interior of the all-terrain vehicle 100, and improving the comfort of the all-terrain vehicle 100.

[0043] In the present embodiment, the area of the first projection plane is greater than or equal to 6500mm 2 and less than or equal to 8000mm 2 ; the area of the second projection plane is greater than or equal to 6500mm 2 and less than or equal to 8000mm 2By the above arrangement, the amount of air introduced into the all-terrain vehicle 100 can be increased, thereby improving the heat dissipation effect and service life of the all-terrain vehicle 100. Specifically, the first flow guide hole 2314a and the second flow guide hole 2314b are both in communication with the accommodation space 23a, so that air enters the accommodation space 23a, thereby improving the heat dissipation effect of the vehicle body cover 23, and further improving the heat dissipation effect and service life of the all-terrain vehicle 100, and improving the comfort of the all-terrain vehicle 100.

[0044] As an implementation manner, the area of the first projection plane and the area of the second projection plane are adjusted according to the arrangement of the exhaust system 18. Specifically, when the exhaust system 18 is arranged on the right side of the all-terrain vehicle 100, the area of the first projection plane is greater than the area of the second projection plane. At this time, the air intake amount of the first flow guide hole 2314a is greater than the air intake amount of the second flow guide hole 2314b, so that more air cools the exhaust system 18, thereby improving the heat dissipation effect of the exhaust system 18, and further improving the heat dissipation effect of the all-terrain vehicle 100. At the same time, since part of the heat discharged by the exhaust system 18 flows in the accommodation space 23a, the heat on the right side of the all-terrain vehicle 100 is discharged through the first flow guide hole 2314a, and the heat on the left side of the all-terrain vehicle 100 is discharged through the second flow guide hole 2314b, thereby improving the heat dissipation effect of the all-terrain vehicle 100. In addition, when the exhaust system 18 is arranged on the right side of the all-terrain vehicle 100, the area of the first projection plane can also be equal to the area of the second projection plane.

[0045] Specifically, when the exhaust system 18 is arranged on the left side of the all-terrain vehicle 100, the area of the first projection plane is less than the area of the second projection plane. At this time, the air intake amount of the first flow guide hole 2314a is less than the air intake amount of the second flow guide hole 2314b, so that more air cools the exhaust system 18, thereby improving the heat dissipation effect of the exhaust system 18, and further improving the heat dissipation effect of the all-terrain vehicle 100. At the same time, since part of the heat discharged by the exhaust system 18 flows in the accommodation space 23a, the heat on the right side of the all-terrain vehicle 100 is discharged through the first flow guide hole 2314a, and the heat on the left side of the all-terrain vehicle 100 is discharged through the second flow guide hole 2314b, thereby improving the heat dissipation effect of the all-terrain vehicle 100. In addition, when the exhaust system 18 is arranged on the left side of the all-terrain vehicle 100, the area of the first projection plane can also be equal to the area of the second projection plane.

[0046] In the embodiment, the projection of the exhaust system 18 on the third projection plane 306 along the front-rear direction of the all-terrain vehicle 100 is a third projection plane. The height of the third projection plane, the height of the first projection plane, and the height of the second projection plane are substantially the same along the up-down direction of the all-terrain vehicle 100. Through the above arrangement, the first flow guide hole 2314a or the second flow guide hole 2314b can better cool the exhaust system 18, and during the driving of the all-terrain vehicle 100, air can substantially cover the exhaust system 18, thereby improving the heat dissipation effect of the exhaust system 18, and further improving the heat dissipation effect of the all-terrain vehicle 100.

[0047] As an implementation manner, the first flow guide plate 2315a and the second flow guide plate 2315b are substantially perpendicular to the third projection plane 306. Through the above arrangement, the flow guide effect of the first flow guide plate 2315a and the second flow guide plate 2315b can be better, thereby improving the air intake amount of the first flow guide hole 2314a and the second flow guide hole 2314b, and further improving the heat dissipation effect and service life of the exhaust system 18, and improving the heat dissipation effect and service life of the all-terrain vehicle 100. In the embodiment, the first flow guide hole 2314a and the second flow guide hole 2314b substantially extend along the front-rear direction of the all-terrain vehicle 100, thereby improving the air intake amount of the first flow guide hole 2314a and the second flow guide hole 2314b, and further improving the heat dissipation effect and service life of the exhaust system 18, and improving the heat dissipation effect and service life of the all-terrain vehicle 100.

[0048] As shown in Figure 7 , the first fender 231 is internally provided with a chamber with a certain volume, which can serve as a first maintenance cavity 2313. Devices that need to be frequently checked, repaired, or replaced in the vehicle, such as automatic oil cups, fuses, relays, and waterproof plugs, can be arranged in the first maintenance cavity 2313. The arrangement of the first maintenance cavity 2313 facilitates the inspection of device wear and replacement of devices, saves maintenance time, and thus reduces labor costs.

[0049] As shown in Figure 7 and 8As shown, the vehicle body cover 23 further comprises a first maintenance cover 234. The first maintenance cover 234 is used to cover the first maintenance cavity 2313, and the first maintenance cover 234 achieves the functions of waterproofing and dustproofing of the first maintenance cavity 2313, thereby ensuring the service life of the components in the first maintenance cavity 2313. The first maintenance cover 234 is connected with the first mudguard 231. As an implementation manner, a connecting portion 2341 is arranged at one end of the first maintenance cover 234, and the first maintenance cover 234 is connected with the first mudguard 231 through the connecting portion 2341, and the connecting portion 2341 can limit the movement of the one end of the first maintenance cover 234 in the front-rear, left-right and up-down directions. A third clamping portion 2342 is further arranged at the other end of the first maintenance cover 234, and the first maintenance cover 234 is connected with the first mudguard 231 through the third clamping portion 2342. As an implementation manner, the third clamping portion 2342 is a clamping hook. The all-terrain vehicle 100 has a symmetry plane 303 perpendicular to the left-right direction, and the all-terrain vehicle 100 is substantially symmetrically arranged about the symmetry plane 303. On the bottom surface of the first maintenance cover 234, one clamping hook is symmetrically arranged on the left and right sides of the symmetry plane 303, and the two clamping hooks can limit the movement of the first maintenance cover 234 in the front-rear, left-right and up-down directions. The first maintenance cover 234 is gap-fitted with the first mudguard 231 at least one end, and a gap space for holding by hand is left. The fixing mode arranged in this way can effectively simplify the disassembly and assembly process, and the disassembly and assembly of the first maintenance cover 234 can be completed without using tools when the first maintenance cavity 2313 is overhauled, and the reusability is better and more convenient and fast.

[0050] The all-terrain vehicle 100 further comprises a control system 21, and the control system 21 comprises an ECU 211 (Electronic Control Unit). The ECU 211 is connected with the engine 111 and can control the ignition start of the engine 111. Generally, the working temperature of the ECU is greater than or equal to -40℃ and less than or equal to 80℃, the ECU cannot withstand high temperature, and contact with water can cause water damage. The all-terrain vehicle is suitable for driving in various environments, often needs to drive in a water environment, and there is a high-temperature area inside the all-terrain vehicle, so the arrangement position of the ECU is particularly important, and generally the ECU needs to be arranged away from the heat source. For example, Figure 9As shown, the vehicle body cover 23 further comprises a second mudguard 232 and a second maintenance cover 235. The second mudguard 232 is located at the rear of the all-terrain vehicle 100, and the second mudguard 232 is connected with the frame 12, which can be used to prevent the second travel wheel 262 from throwing mud into the all-terrain vehicle 100 or the user. In this embodiment, a second maintenance cavity 2321 is formed in the second mudguard 232, the second maintenance cavity 2321 is arranged away from the power system 11, and the second maintenance cavity 2321 is arranged away from the travel assembly 26, that is, in the up-down direction of the all-terrain vehicle 100, the second maintenance cavity 2321 is as far away from the travel assembly 26 as possible. As Figure 10 As shown, the ECU 211 is installed in the second maintenance cavity 2321. In the working environment of the all-terrain vehicle 100 wading, such arrangement can avoid water entering the second maintenance cavity 2321, and prevent the ECU 211 from being damaged due to water immersion. The second maintenance cover 235 is arranged on the second maintenance cavity 2321, and the second maintenance cover 235 is used to shield the second maintenance cavity 2321 and the components stored in the second maintenance cavity 2321. As an implementation manner, the second maintenance cover 235 is provided with a first connecting portion 2351 and a second connecting portion 2352, the first connecting portion 2351 is clamped with the second mudguard 232, and the first connecting portion 2351 can limit the movement of the second maintenance cover 235 in the up-down direction, and the second connecting portion 2352 is connected and fixed with the second mudguard 232 by bolts, so that the second maintenance cover 235 is fixedly installed on the second maintenance cavity 2321. Such arrangement reduces the disassembly and assembly difficulty of the second maintenance cover 235, which can facilitate the user to open the second maintenance cover 235, and such arrangement can arrange the ECU 211 in an environment which is easy to maintain and has high safety.

[0051] As shown in Figure 11 and Figure 12 As shown, the vehicle body cover 23 further comprises a side cover assembly 237 and a footrest 239. As an implementation manner, the footrest 239 comprises a first footboard 2391 and a second footboard 2392, the first footboard 2391 is arranged on the left side of the all-terrain vehicle 100, and the first footboard 2391 is connected between the first mudguard 231 and the second mudguard 232. The second footboard 2392 is arranged on the right side of the all-terrain vehicle 100, and the second footboard 2392 is connected between the first mudguard 231 and the second mudguard 232. In the front-rear direction of the all-terrain vehicle 100, one end of the first footboard 2391 is connected with the first mudguard 231, the other end of the first footboard 2391 is connected with the second mudguard 232, one end of the second footboard 2392 is connected with the first mudguard 231, and the other end of the second footboard 2392 is connected with the second mudguard 232.

[0052] The power system 11 is the source of power for the entire all-terrain vehicle 100 to travel. The power system 11 generates a large amount of heat when working. The gas temperature around the engine 111 is usually greater than or equal to 600°C and less than or equal to 800°C. In order to prevent the internal parts of the all-terrain vehicle 100 from malfunctioning due to excessive temperature, it is necessary to cool the power system 11.

[0053] Referring to Figure 11 and Figure 12 As shown in FIG. 7, the side cover assembly 237 includes a first side cover 2371, a second side cover 2372, a first heat insulation cover 2373, and a second heat insulation cover 2374. The first side cover 2371 and the second side cover 2372 are substantially symmetrically arranged about a symmetry plane 303 in a left-right direction of the all-terrain vehicle 100. Specifically, the first side cover 2371 is arranged on the left side of the all-terrain vehicle 100, and the second side cover 2372 is arranged on the right side of the all-terrain vehicle 100. The first heat insulation cover 2373 is arranged on the straddle portion on the side of the engine 111. The straddle portion refers to the portion of the all-terrain vehicle 100 that is close to the inside of the user's legs when the user drives the all-terrain vehicle 100. A first exhaust passage is formed inside the all-terrain vehicle 100, which passes through the inside of the first heat insulation cover 2373 from the front portion of the vehicle frame 12 to the rear portion of the vehicle frame 12. As an implementation, the space between the first heat insulation cover 2373 and the engine 111 in the left-right direction of the all-terrain vehicle 100 forms a space that communicates with the first exhaust passage, and at the same time, completely separates the inside of the all-terrain vehicle 100 from the outside of the all-terrain vehicle 100 on the left side of the all-terrain vehicle 100. As an implementation, the space of the first exhaust passage can be increased by increasing the distance between the engine 111 and the first heat insulation cover 2373, thereby increasing the amount of air passing between the engine 111 and the first heat insulation cover 2373, which is beneficial to improve the heat dissipation efficiency and prevent the user's legs from being burned. The first heat insulation cover 2373 is arranged between the first mudguard 231 and the second mudguard 232. As shown in FIG. 7, the second heat insulation cover 2374 is arranged on the straddle portion on the side of the engine 111. The second heat insulation cover 2374 is arranged between the first mudguard 231 and the second mudguard 232. Figure 13As shown, the first heat insulation cover 2373 is connected through a plug-in structure between the first footboard 2391, and one end of the first heat insulation cover 2373 is connected with the first mudguard 231, and the end of the first heat insulation cover 2373 away from the first mudguard 231 is connected with the second mudguard 232. Specifically, the first heat insulation cover 2373 is connected with the first footboard 2391 through the connecting part 2373b, and the first footboard 2391 is provided with a plug-in part corresponding to the connecting part 2373b, which can be a hole, a slot or the like structure, and the connecting part 2373b is clamped with the plug-in part, so as to limit and fix the first heat insulation cover 2373, avoiding the first heat insulation cover 2373 jumping in the left-right or front-back direction on the first footboard 2391. One end of the first heat insulation cover 2373 is connected with the first mudguard 231 through a bolt, and the end of the first heat insulation cover 2373 away from the first mudguard 231 is connected with the second mudguard 232, which limits the first heat insulation cover 2373 from jumping between the first mudguard 231 and the second mudguard 232 through the bolt, avoiding the first heat insulation cover 2373 from shaking during the driving of the all-terrain vehicle 100. In the embodiment, the connection mode of the first heat insulation cover 2373 with the first mudguard 231 and the second mudguard 232 can also be other modes, and the position and structure of the plug-in part are not unique. As an implementation mode, the quick-release cover 2373a is further provided on the outer surface of the first heat insulation cover 2373. The quick-release cover 2373a is provided on the side of the first heat insulation cover 2373 close to the outside of the all-terrain vehicle 100, and the quick-release cover 2373a is clamped on the first heat insulation cover 2373, and the quick-release cover 2373a and the first heat insulation cover 2373 form a holding part. During maintenance, the quick-release cover 2373a can be disassembled by hand through the holding part, without the need of using tools, saving time and cost, and being convenient and fast. The width of the holding part is greater than the width of the human finger, and specifically, the width of the holding part can be greater than or equal to 1 cm, so as to ensure that the human finger can enter the holding part, thereby disassembling the quick-release cover 2373a by hand through the holding part. It can be understood that the connection mode of the first heat insulation cover 2373 and the quick-release cover 2373a and the setting of the fixing structure are not unique. In order to ensure the good running of the all-terrain vehicle 100, the parts of the engine 111 need to be frequently checked and maintained, and the quick-release cover 2373a is provided on the side of the engine 111, which not only reduces the disassembly difficulty of the quick-release cover 2373a, but also shortens the checking and maintenance time of the engine 111 each time. When the first heat insulation cover 2373 is installed, the connecting part 2373b of the first heat insulation cover 2373 is connected with the plug-in part on the first footboard 2391, so as to limit the movement of the first heat insulation cover 2373 in the left-right or front-back direction.The first heat insulation cover 2373 is fixed with the first mudguard 231 by bolts, and the first heat insulation cover 2373 is fixed with the second mudguard 232 by bolts to lock the movement of the first heat insulation cover 2373 in all directions, thereby completing the installation of the first heat insulation cover 2373.

[0054] As shown in Figure 14 The second heat insulation cover 2374 is substantially symmetrically arranged with the first heat insulation cover 2373 relative to the symmetry plane 303, and the second heat insulation cover 2374 is detachably fixed on the right side of the ATV 100. The second heat insulation cover 2374 is arranged on the straddle part on the side of the transmission assembly 14. A second exhaust passage is formed inside the ATV 100, which passes through the inner side of the second heat insulation cover 2374 from the front of the frame 12 and extends to the rear of the frame 12. As an implementation manner, the second heat insulation cover 2374 is substantially the same as the first heat insulation cover 2373 in structure, shape, material, etc., which will not be described here. During the driving of the ATV 100, the ambient air entering from the front of the frame main body 121 flows through the first heat insulation cover 2373 through the first exhaust passage, taking away the heat accumulated between the engine 111 and the first heat insulation cover 2373, and flows through the second heat insulation cover 2374 through the second exhaust passage, taking away the heat between the transmission assembly 14 and the second heat insulation cover 2374, reducing the heat transmitted from the side of the frame 12 to the straddle part of the power system 11, and further reducing the heat transmitted to the user's legs, effectively reducing the temperature of the user's legs and improving the driving comfort. The second heat insulation cover 2374 is also provided with a heat insulation part 2374a, which can isolate the heat inside the ATV 100. As an implementation manner, the heat insulation part 2374a is made of a material including aluminum foil and ceramic fiber. In the present application, the first heat insulation cover 2373 and the second heat insulation cover 2374 are respectively closed and covered on both sides of the ATV 100, which makes the inside and outside of the ATV 100 isolated in the left-right direction, so that the heat dissipation air duct inside the ATV 100 extends from the front to the rear of the ATV 100. This arrangement effectively improves the ventilation efficiency inside the ATV 100 and can effectively reduce the noise of the engine 111 during the starting or driving stage. Among them, the heat dissipation air duct refers to the exhaust passage formed by the first exhaust passage and the second exhaust passage.

[0055] As shown in Figure 15As shown, the all-terrain vehicle 100 also includes a fuel system 13, located at the front of the all-terrain vehicle 100 and mounted on the frame 12. The fuel system 13 is used to supply fuel to the power system 11. In one implementation, the fuel system 13 includes a fuel tank 132, a charcoal canister 133, and a pipeline 135. The fuel tank 132 stores fuel and has a fuel vapor port. The charcoal canister 133 is connected to the fuel vapor port via the pipeline 135 and contains activated carbon to absorb excess fuel vapor in the fuel tank 132. The fuel tank 132 is mounted on the frame 12. Specifically, the fuel tank 132 is at least partially mounted on the first main beam 1211 and connected to the first main beam 1211. The fuel tank 132 is at least partially mounted on the second main beam 1212 (e.g., ...). Figure 4 As shown, the fuel tank 132 is connected to the second main beam 1212. The fuel tank 132 is at least partially located below the first main beam 1211 or the second main beam 1212. The charcoal canister 133 is mounted on the frame 12 and is arranged in front of the fuel tank 132. In the left-right direction of the all-terrain vehicle 100, the charcoal canister 133 can be arranged on the left or right side of the all-terrain vehicle 100.

[0056] like Figure 16 and Figure 17As shown, the vehicle body cover 23 further comprises a fuel tank guard 238. The fuel tank guard 238 is arranged above the fuel tank 132 and is used to protect the fuel tank 132. The fuel tank guard 238 is provided with a fixing portion 2381 on the side close to the fuel tank 132, and the fuel tank guard 238 is connected with the first fender 231 through the fixing portion 2381 and connected with the side cover assembly 237 through the fixing portion 2381. In the left-right direction of the all-terrain vehicle 100, one side of the fixing portion 2381 is connected with the first side cover 2371, and the side of the fixing portion 2381 away from the first side cover 2371 is connected with the second side cover 2372. The fixing portion 2381 is arranged on the side of the fuel tank guard 238 close to the fuel tank 132, i.e. in the up-down direction of the all-terrain vehicle 100, the fixing portion 2381 is arranged below the fuel tank guard 238. The fixing portion 2381 comprises a bolt fixing end 2381a, a clamping end 2381b and a plug hole 2381c, and the bolt fixing end 2381a comprises a first bolt fixing end and a second bolt fixing end. In the front-rear direction of the all-terrain vehicle 100, the first bolt fixing end is arranged at the front end of the fuel tank guard 238, and the second bolt fixing end is arranged at the rear end of the fuel tank guard 238. The bolt fixing end 2381a enables the fuel tank guard 238 to be connected with the first side cover 2371 through bolts. The first bolt fixing end and the second bolt fixing end have a space range, and the clamping end 2381b and the plug hole 2381c are arranged in the space range. The clamping end 2381b can be clamped and matched with the first side cover 2371 to limit the movement of the fuel tank guard 238 in the up-down direction, and the plug hole 2381c can also be clamped and matched with the first side cover 2371 to limit the movement of the fuel tank guard 238 in the left-right direction and the front-rear direction, thereby realizing the connection between the first side cover 2371 and the fuel tank guard 238. Similarly, the second side cover 2372 is connected with the fuel tank guard 238 in the same way as the first side cover 2371, and details are not repeated. Such an arrangement enables the fuel tank guard 238, the first side cover 2371 and the second side cover 2372 to be connected and fixed, and then uniformly assembled on the all-terrain vehicle 100. This method can reduce the assembly process, improve the assembly efficiency, and facilitate integrated disassembly and installation. The first side cover 2371 is clamped with the mounting bracket assembly 24, and the second side cover 2372 is clamped with the mounting bracket assembly 24. The first side cover 2371 is gap-fitted with the second fender 232, and the second side cover 2372 is gap-fitted with the second fender 232, thereby leaving a gap space on both sides of the all-terrain vehicle 100 for a person to hold, facilitating installation and disassembly. One end of the first side cover 2371 is clamped and fixed with the first heat insulation cover 2373, and one end of the second side cover 2372 is clamped and fixed with the second heat insulation cover 2374.Since the first side cover 2371 and the second side cover 2372 are in close contact with the human body, the overheating of the first side cover 2371 and the second side cover 2372 will bring discomfort to the user, so a heat insulation plate is further arranged on the inner side of the first side cover 2371 and the second side cover 2372, which is used to insulate heat and reduce heat transfer. The heat insulation plate is made of multi-layer composite material, and as an implementation manner, the heat insulation plate is made of aluminum foil and ceramic fiber. In the embodiment, the fuel tank cover plate 238, the first side cover 2371 and the second side cover 2372 are integrally disassembled, and the connection between the three adopts a detachable fixing structure, which can facilitate repeated installation and disassembly. When disassembled, the user can hold the gap of the first side cover 2371 or the second side cover 2372 by hand, pull the first side cover 2371 or the second side cover 2372, so that the first side cover 2371 or the second side cover 2372 is disconnected with the fuel tank cover plate 238 everywhere, that is, the integrally disassembly of the first side cover 2371, the second side cover 2372 and the fuel tank cover plate 238 is completed. This tool-free disassembly method is simple and fast, convenient for maintenance, greatly improves the maintenance efficiency and greatly reduces the time cost.

[0057] Generally, a ventilation net is arranged at the front of the all-terrain vehicle, which is used to introduce ambient air from the front side of the all-terrain vehicle. Since the all-terrain vehicle usually works in the wild environment, garbage such as grass and leaves is easy to accumulate on the ventilation net when the all-terrain vehicle is running. The ventilation net and the fender in the prior art are integrally arranged, which often increases the cleaning difficulty of the ventilation net, and makes the garbage on the ventilation net time-consuming and laborious to clean. In the present application, as shown in Figure 18 The vehicle body cover 23 further includes a ventilation net 236. The ventilation net 236 is located at the front of the all-terrain vehicle 100, and the ventilation net 236 is arranged on the first fender 231. The ventilation net 236 is provided with grid-shaped ventilation holes, and a connecting portion 2361 for connecting the first fender 231 is arranged on the inner side of the ventilation net 236. Among them, the inner side of the ventilation net 236 refers to the side of the ventilation net 236 close to the first fender 231. The connecting portion 2361 is arranged on the periphery of the ventilation net 236, and the connecting portion 2361 can be clamped with the first fender 231. As shown in Figure 19As shown, specifically, in the up-down and left-right directions of the all-terrain vehicle 100, the connecting portion 2361 includes a first connecting portion 2361a, a second connecting portion 2361b, a third connecting portion 2361c, and a fourth connecting portion 2361d. The first connecting portion 2361a is arranged at the upper end of the ventilation screen 236, the second connecting portion 2361b is arranged at the bottom end of the ventilation screen 236, the third connecting portion 2361c is arranged at the left side of the ventilation screen 236, and the fourth connecting portion 2361d is arranged at the right side of the ventilation screen 236. As an implementation manner, the first connecting portion 2361a is clamped with one end of the first mudguard 231, and the first connecting portion 2361a can limit the movement of the ventilation screen 236 in the left-right direction and the up-down direction. The second connecting portion 2361b is clamped with one end of the first mudguard 231 away from the first connecting portion 2361a, and the second connecting portion 2361b can limit the movement of the ventilation screen 236 in the front-rear direction. The third connecting portion 2361c is clamped with one side of the first mudguard 231, and the fourth connecting portion 2361d is clamped with one side of the first mudguard 231 away from the third connecting portion 2361c, and the third connecting portion 2361c and the fourth connecting portion 2361d can limit the movement of the ventilation screen 236 in the up-down direction and the left-right direction. The present application cooperates with the first mudguard 231 through the connecting portion 2361 arranged around the ventilation screen 236, so as to limit and fix the ventilation screen 236 in each direction, so that the installation of the ventilation screen 236 is more firm and reliable. In this embodiment, the fixing mode of each connecting portion 2361 on the ventilation screen 236 is a detachable fixing mode, which greatly simplifies the disassembly and assembly process, and the user can disassemble and assemble the ventilation screen 236 manually without using tools, so that the ventilation screen 236 is easy to clean, and the ventilation screen 236 of the present application can be adapted to multiple installations and disassemblies, and is not easy to deform.
