[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in specific embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0034] like Figure 1 and Figure 2As shown, the all-terrain vehicle 100 includes a frame 12, a fuel system 13, a steering assembly 16, an electrical system 17, an exhaust system 18, a control assembly 22, a body panel 23, a mounting bracket assembly 24, an intake system 25, a running gear 26, a suspension assembly 27, and a seat assembly 28. The frame 12 supports the steering assembly 16, the exhaust system 18, and the body panel 23. The mounting bracket assembly 24 is mounted on the frame 12. The steering assembly 16 controls the rotation of the running gear 26. The exhaust system 18 discharges gases generated during the operation of the all-terrain vehicle 100 to the external environment. The control assembly 22 is mounted on the frame 12 and connected to the body panel 23. The suspension assembly 27 connects the running gear 26 to the frame 12. To clearly illustrate the technical solution of the present invention, the following are also defined: Figure 1 The front, back, left, right, top, and bottom sides are shown.
[0035] like Figure 2 As shown, the running gear 26 includes a first running wheel 261 and a second running wheel 262. Both the first running wheel 261 and / or the second running wheel 262 can serve as drive wheels for the all-terrain vehicle 100, and the first running wheel 261 is connected to the steering assembly 16 and can be rotated. The suspension assembly 27 includes a front suspension 271 and a rear suspension 272 (see...). Figure 1 The first traveling wheel 261 is connected to the frame 12 via the front suspension 271, and the second traveling wheel 262 is connected to the frame 12 via the rear suspension 272.
[0036] like Figure 3 As shown, the all-terrain vehicle 100 also includes a power system 11 and a transmission assembly 14. The power system 11 is mounted on the frame 12 and provides power to the all-terrain vehicle 100. The power system 11 includes an engine 111, which is connected to the transmission assembly 14. The transmission assembly 14 can change the driving force and travel speed of the all-terrain vehicle 100. 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 frame 12 is a metal frame, including a frame body 121 and a front support frame 122. The frame body 121 includes 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 frame body 121 can be manufactured by welding. In the front-rear direction, the front support frame 122 is located on the front side of the frame body 121. The front support frame 122 serves as an extension of the frame 12, which can extend the overall length of the frame 12, allowing the frame 12 to be equipped with more devices.
[0038] like Figure 5 and Figure 6As shown, the vehicle body panel 23 includes a first mudguard 231. The first mudguard 231 is located at the front of the all-terrain vehicle 100 and is mounted on the frame 12. The first mudguard 231 prevents the first wheel 261 from throwing mud into the interior of the all-terrain vehicle 100 or onto the user. The all-terrain vehicle 100 has a plane of symmetry 303 perpendicular to the left-right direction, and the all-terrain vehicle 100 is substantially symmetrically arranged about the plane of symmetry 303. The first mudguard 231 has a substantially symmetrical structure about the plane of symmetry 303, and the first wheel 261 on the right side of the all-terrain vehicle 100 is the right wheel. The first mudguard 231 is provided with a guide hole 2314, a guide plate 2315, a windward surface 2311, and an inlet surface 2312. The guide hole 2314 includes a first guide hole 2314a and a second guide hole 2314b. The deflector 2315 includes a first deflector 2315a and a second deflector 2315b. The description focuses on the position of the right drive wheel of the all-terrain vehicle 100. In the longitudinal direction of the all-terrain vehicle 100, the windward surface 2311 is positioned near the rear of the right drive wheel, and is used to receive ambient air entering from the front of the all-terrain vehicle 100 during its movement. An air inlet surface 2312 is connected to the windward surface 2311, and is positioned on the side of the right drive wheel facing inwards. A first air inlet hole 2314a is provided at the connection between the air inlet surface 2312 and the windward surface 2311; that is, the first air inlet hole 2314a is at least partially located on both the air inlet surface 2312 and the windward surface 2311. The first air guide hole 2314a is used to guide the ambient air entering from 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 the operation of the all-terrain vehicle 100, the incoming ambient air continuously converges on the windward surface 2311, causing the air pressure on the windward surface 2311 to gradually increase, while the air pressure on the inlet surface 2312 is low, thus creating a pressure difference. Ambient air flows from areas of high pressure to areas of low pressure, that is, ambient air flows from the windward surface 2311 to the inlet surface 2312, and is guided into the interior of the vehicle body through the first air guide hole 2314a. By rationally arranging the position of the first air guide hole 2314a, and utilizing the ambient air carried by the vehicle body during operation, the airflow inside the vehicle body can be increased, significantly reducing the internal temperature of the vehicle body and improving riding comfort. Specifically, the vehicle body cover 23 forms an accommodating space 23a (see reference). Figure 1 The first air guide hole 2314a connects to the accommodating space 23a, thereby allowing air to enter the accommodating space 23a, which improves the heat dissipation effect of the body cover 23, 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.
[0039] Specifically, the first mudguard 231 also includes several first deflector plates 2315a. These first deflector plates 2315a are disposed within the first deflector hole 2314a, dividing the first deflector hole 2314a into several ventilation holes. During the operation of the all-terrain vehicle 100, the first deflector plates 2315a can increase the air intake of the first deflector hole 2314a, thereby increasing the amount of air introduced into the all-terrain vehicle 100, and thus improving the heat dissipation effect and service life of the all-terrain vehicle 100. Furthermore, through the above arrangement, during the operation of the all-terrain vehicle 100, the first deflector plates 2315a can prevent mud and water from entering the first deflector hole 2314a, preventing blockage and affecting the air intake efficiency of the first deflector hole 2314a, thereby improving the air intake efficiency of the first deflector hole 2314a, and further improving the heat dissipation effect and service life of the all-terrain vehicle 100.
[0040] In this embodiment, the all-terrain vehicle 100 further includes a second air intake 2314b and a second air deflector 2315b. Both the second air intake 2314b and the second air deflector 2315b are located on the left side of the all-terrain vehicle 100. Specifically, the first air intake 2314a and the second air intake 2314b are arranged substantially symmetrically about the plane of symmetry 303, and the first air deflector 2315a and the second air deflector 2315b are also arranged substantially symmetrically about the plane of symmetry 303. A plurality of second air deflectors 2315b are disposed within the second air intake 2314b, dividing the second air intake 2314b into a plurality of ventilation holes. During the operation of the all-terrain vehicle 100, the second air deflectors 2315b can increase the air intake volume of the second air intake 2314b, thereby increasing the amount of air introduced into the all-terrain vehicle 100, and thus improving the heat dissipation effect and service life of the all-terrain vehicle 100. Specifically, the second air guide hole 2314b connects to the accommodating space 23a, thereby allowing air to enter the accommodating space 23a, thereby improving the heat dissipation effect of the body cover 23, and thus improving the heat dissipation effect and service life inside the all-terrain vehicle 100, and improving the comfort of the all-terrain vehicle 100.
[0041] Furthermore, through the above-mentioned configuration, during the operation of the all-terrain vehicle 100, the second deflector 2315b can prevent mud and water from entering the second deflector hole 2314b, thus preventing blockage and affecting the air intake efficiency of the second deflector hole 2314b, thereby improving the air intake efficiency of the second deflector hole 2314b and consequently 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 left and right windward surfaces 2311 are basically symmetrically arranged about the plane of symmetry 303, and the left and right air inlet surfaces 2312 are also basically symmetrically arranged about the plane of symmetry 303. Specifically, the effects and connection relationships of the left and right windward surfaces 2311 and 2312 are basically the same.
[0042] As one implementation, within the third projection plane 306 perpendicular to the longitudinal direction of the all-terrain vehicle 100, the projection of the first guide hole 2314a along the longitudinal direction of the all-terrain vehicle 100 onto the third projection plane 306 is the first projection plane, and the projection of the second guide hole 2314b along the longitudinal direction of the all-terrain vehicle 100 onto the third projection plane 306 is the second projection plane. The area of the first projection plane is greater than or equal to 5800 mm². 2 And less than or equal to 9000mm 2 The area of the second projection plane is greater than or equal to 5800 mm². 2 And less than or equal to 9000mm 2 The above configuration increases the amount of air introduced into the all-terrain vehicle 100, thereby improving its heat dissipation and service life. Specifically, both the first air guide hole 2314a and the second air guide hole 2314b are connected to the receiving space 23a, allowing air to enter the receiving space 23a, thus improving the heat dissipation of the body panel 23, and consequently improving the heat dissipation and service life of the all-terrain vehicle 100, and enhancing the comfort of the all-terrain vehicle 100.
[0043] In this embodiment, the area of the first projection plane is greater than or equal to 6500 mm². 2 And less than or equal to 8000mm 2 The area of the second projection plane is greater than or equal to 6500 mm². 2 And less than or equal to 8000mm 2The above configuration increases the amount of air introduced into the all-terrain vehicle 100, thereby improving its heat dissipation and service life. Specifically, both the first air guide hole 2314a and the second air guide hole 2314b are connected to the receiving space 23a, allowing air to enter the receiving space 23a, thus improving the heat dissipation of the body panel 23, and consequently improving the heat dissipation and service life of the all-terrain vehicle 100, and enhancing the comfort of the all-terrain vehicle 100.
[0044] As one implementation, the areas of the first and second projection planes are adjusted according to the arrangement of the exhaust system 18. Specifically, when the exhaust system 18 is located on the right side of the all-terrain vehicle 100, the area of the first projection plane is larger than the area of the second projection plane. In this case, the air intake of the first guide hole 2314a is greater than the air intake of the second guide hole 2314b, thereby allowing more air to cool the exhaust system 18, improving its heat dissipation effect, and consequently improving the heat dissipation effect of the all-terrain vehicle 100. Simultaneously, since some of the heat discharged by the exhaust system 18 flows within the accommodating space 23a, while the first guide hole 2314a discharges heat from the right side of the all-terrain vehicle 100, the second guide hole 2314b can discharge heat from the left side of the all-terrain vehicle 100, thus improving the heat dissipation effect of the all-terrain vehicle 100. Furthermore, when the exhaust system 18 is located 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 located on the left side of the all-terrain vehicle 100, the area of the first projection plane is smaller than the area of the second projection plane. At this time, the air intake volume of the first guide hole 2314a is less than the air intake volume of the second guide hole 2314b, thereby allowing more air to cool the exhaust system 18, improving its heat dissipation effect, and consequently improving the heat dissipation effect of the all-terrain vehicle 100. Simultaneously, since some of the heat discharged by the exhaust system 18 flows within the accommodating space 23a, while the second guide hole 2314b discharges heat from the left side of the all-terrain vehicle 100, the first guide hole 2314a can discharge heat from the right side of the all-terrain vehicle 100, thus improving the heat dissipation effect of the all-terrain vehicle 100. Furthermore, when the exhaust system 18 is located 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 this embodiment, the projection of the exhaust system 18 onto the third projection plane 306 along the longitudinal direction of the all-terrain vehicle 100 is the third projection plane. Along the vertical direction of the all-terrain vehicle 100, 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. Through this arrangement, the first guide hole 2314a or the second guide hole 2314b can better cool the exhaust system 18, ensuring that air essentially covers the exhaust system 18 during the operation of the all-terrain vehicle 100, thereby improving the heat dissipation effect of the exhaust system 18 and consequently improving the heat dissipation effect of the all-terrain vehicle 100.
[0047] In one implementation, the first guide vane 2315a and the second guide vane 2315b are positioned substantially perpendicular to the third projection plane 306. This configuration improves the airflow guiding effect of the first guide vane 2315a and the second guide vane 2315b, thereby increasing the air intake volume of the first guide hole 2314a and the second guide hole 2314b, and consequently improving the heat dissipation effect and service life of the exhaust system 18, and ultimately improving the heat dissipation effect and service life of the all-terrain vehicle 100. In this embodiment, the first guide hole 2314a and the second guide hole 2314b extend substantially along the longitudinal direction of the all-terrain vehicle 100, thereby increasing the air intake volume of the first guide hole 2314a and the second guide hole 2314b, and consequently improving the heat dissipation effect and service life of the exhaust system 18, and ultimately improving the heat dissipation effect and service life of the all-terrain vehicle 100.
[0048] like Figure 7 As shown, the first mudguard 231 contains a chamber with a certain volume, which can serve as a first maintenance chamber 2313. Components that require frequent inspection, repair, or replacement can be housed in the first maintenance chamber 2313, such as automatic oil cups, fuses, relays, and waterproof valves. The first maintenance chamber 2313 facilitates the inspection and replacement of worn components, saving maintenance time and thus reducing labor costs.
[0049] like Figure 7 and 8As shown, the body panel 23 also includes a first maintenance cover 234. The first maintenance cover 234 is used to cover the first maintenance cavity 2313, providing waterproofing and dustproofing to the first maintenance cavity 2313, thereby ensuring the service life of the components inside the first maintenance cavity 2313. The first maintenance cover 234 is connected to the first mudguard 231. In one implementation, a connecting part 2341 is provided at one end of the first maintenance cover 234, through which the first maintenance cover 234 is connected to the first mudguard 231. The connecting part 2341 can restrict the movement of one end of the first maintenance cover 234 in the front-back, left-right, and up-down directions. A third locking part 2342 is also provided at the other end of the first maintenance cover 234, through which the first maintenance cover 234 is connected to the first mudguard 231. In one implementation, the third locking part 2342 is a hook. The all-terrain vehicle 100 has a symmetrical plane 303 perpendicular to the left-right direction, and the all-terrain vehicle 100 is basically symmetrically arranged about the symmetrical plane 303. On the bottom surface of the first maintenance cover 234, a hook is symmetrically arranged on each side with the symmetrical plane 303 as the plane of symmetry. The two hooks can restrict the movement of the first maintenance cover 234 in the front-back, left-right, and up-down directions. At least one end of the first maintenance cover 234 is clearance-fitted with the first mudguard 231, leaving a gap space for a person to hold. This fixing method can effectively simplify the disassembly and assembly process. When inspecting the first maintenance cavity 2313, the first maintenance cover 234 can be disassembled and assembled without the use of tools, which improves reusability and makes it more convenient and faster.
[0050] The all-terrain vehicle 100 also includes a control system 21, which includes an ECU 211 (Electronic Control Unit). The ECU 211 is connected to the engine 111 and can control the ignition and starting of the engine 111. Typically, the operating temperature of an ECU is greater than or equal to -40°C and less than or equal to 80°C. The ECU cannot withstand high temperatures and is susceptible to water damage upon contact with water. All-terrain vehicles are suitable for driving in various environments, frequently requiring operation in wading conditions. Furthermore, there are high-temperature areas inside all-terrain vehicles, making the placement of the ECU particularly important. Typically, the ECU needs to be located away from heat sources and areas prone to heat. Figure 9As shown, the vehicle body panel 23 also includes 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 is connected to the frame 12, serving to prevent the second wheels 262 from throwing mud into the interior of the all-terrain vehicle 100 or onto the user. In this embodiment, a second maintenance cavity 2321 is formed within the second mudguard 232. The second maintenance cavity 2321 is located away from the power system 11 and away from the running gear 26, meaning that the distance between the second maintenance cavity 2321 and the running gear 26 is as far as possible in the vertical direction of the all-terrain vehicle 100. Figure 10 As shown, the ECU 211 is installed inside the second maintenance compartment 2321. In the wading environment of the all-terrain vehicle 100, this arrangement prevents water from entering the second maintenance compartment 2321, thus preventing damage to the ECU 211 due to water immersion. A second maintenance cover 235 is disposed on the second maintenance compartment 2321, and the second maintenance cover 235 is used to cover the second maintenance compartment 2321 and the components stored within it. In one implementation, the second maintenance cover 235 is provided with a first connecting portion 2351 and a second connecting portion 2352. The first connecting portion 2351 engages with the second mudguard 232, restricting the vertical movement of the second maintenance cover 235. The second connecting portion 2352 is connected and fixed to the second mudguard 232 by bolts, thereby fixing the second maintenance cover 235 onto the second maintenance compartment 2321. This configuration reduces the difficulty of removing and installing the second maintenance cover 235, making it easier for users to open the second maintenance cover 235. At the same time, this configuration allows the ECU 211 to be placed in an environment that is easy to maintain and has a high level of safety.
[0051] like Figure 11 and Figure 12 As shown, the vehicle body panel 23 also includes a side cover assembly 237 and a footrest 239. In one implementation, the footrest 239 includes a first foot pedal 2391 and a second foot pedal 2392. The first foot pedal 2391 is located on the left side of the all-terrain vehicle 100 and connects between the first mudguard 231 and the second mudguard 232. The second foot pedal 2392 is located on the right side of the all-terrain vehicle 100 and connects between the first mudguard 231 and the second mudguard 232. In the longitudinal direction of the all-terrain vehicle 100, one end of the first foot pedal 2391 is connected to the first mudguard 231, and the other end of the first foot pedal 2391 is connected to the second mudguard 232. Similarly, one end of the second foot pedal 2392 is connected to the first mudguard 231, and the other end of the second foot pedal 2392 is connected to the second mudguard 232.
[0052] The power system 11 is the power source for the entire all-terrain vehicle 100. The power system 11 generates a lot of heat when it is 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 essential to cool down the power system 11.
[0053] See Figure 11 and Figure 12 As shown, 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. Within a plane of symmetry 303 perpendicular to the left-right direction of the all-terrain vehicle 100, the first side cover 2371 and the second side cover 2372 are arranged substantially symmetrically about the plane of symmetry 303. Specifically, the first side cover 2371 is located on the left side of the all-terrain vehicle 100, and the second side cover 2372 is located on the right side of the all-terrain vehicle 100. The first heat insulation cover 2373 is located on the straddle section next to the engine 111. The straddle section refers to the part of the all-terrain vehicle 100 that is close to the inside of the user's legs when driving the vehicle. A first exhaust channel is formed inside the all-terrain vehicle 100, flowing from the front of the frame 12, through the inside of the first heat insulation cover 2373, and extending to the rear of the frame 12. As one implementation, in the left-right direction of the all-terrain vehicle 100, the first heat shield 2373 and the engine 111 form a space connecting to the first exhaust passage, while completely isolating the interior and exterior of the vehicle on the left side. As another implementation, increasing the distance between the engine 111 and the first heat shield 2373 increases the size of the first exhaust passage, thereby increasing the airflow between the engine 111 and the first heat shield 2373, which helps improve heat dissipation efficiency and prevents burns to the user's legs. The first heat shield 2373 is positioned between the first mudguard 231 and the second mudguard 232. Figure 13As shown, the first heat insulation cover 2373 and the first foot pedal 2391 are connected by a plug-in structure. One end of the first heat insulation cover 2373 is connected to the first mudguard 231, and the end of the first heat insulation cover 2373 away from the first mudguard 231 is connected to the second mudguard 232. Specifically, the first heat insulation cover 2373 is connected to the first foot pedal 2391 through a connecting part 2373b. The first foot pedal 2391 is provided with a plug-in part corresponding to the connecting part 2373b. The plug-in part can be a hole, groove, or other structure. The first heat insulation cover 2373 is fixed by engaging with the connecting part 2373b, thereby preventing the first heat insulation cover 2373 from jumping in the left-right or front-back direction on the first foot pedal 2391. One end of the first heat insulation cover 2373 is connected to the first mudguard 231 by bolts, and the other end of the first heat insulation cover 2373 away from the first mudguard 231 is connected to the second mudguard 232. This method of fixing with bolts restricts the movement of the first heat insulation cover 2373 between the first mudguard 231 and the second mudguard 232, preventing the first heat insulation cover 2373 from shaking during the operation of the all-terrain vehicle 100. In this embodiment, the connection method between the first heat insulation cover 2373 and the first mudguard 231 and the second mudguard 232 can also be other methods. Similarly, the location and structure of the plug-in part are not unique. As one implementation, a quick-release cover 2373a is also provided on the outer surface of the first heat insulation cover 2373. The quick-release cover 2373a is located on the side of the first heat insulation cover 2373 near the outside of the all-terrain vehicle 100. The quick-release cover 2373a snaps onto the first heat insulation cover 2373, and together they form a grip. During maintenance, the quick-release cover 2373a can be removed manually using the grip, without the need for tools, saving time and effort. The width of the grip is greater than the width of a human finger; specifically, the width can be greater than or equal to 1 cm to ensure that a human finger can enter the grip for manual removal of the quick-release cover 2373a. It is understandable that the connection method and fixing structure of the first heat insulation cover 2373 and the quick-release cover 2373a are not unique. To ensure the proper operation of the all-terrain vehicle 100, frequent inspections and maintenance of the engine 111's components are required. The quick-release cover 2373a is located on the side of the engine 111. This design not only reduces the difficulty of removing the quick-release cover 2373a but also shortens the time required for each inspection / maintenance of the engine 111. When installing the first heat insulation cover 2373, the connecting part 2373b of the first heat insulation cover 2373 mates with the insertion part on the first foot pedal 2391 to restrict the movement of the first heat insulation cover 2373 in the left-right or front-back directions.The first heat insulation cover 2373 is fixed to the first mudguard 231 by bolts, and the first heat insulation cover 2373 is fixed to 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] like Figure 14 As shown, the second heat shield 2374 and the first heat shield 2373 are arranged substantially symmetrically with respect to the plane of symmetry 303. The second heat shield 2374 is detachably fixed to the right side of the all-terrain vehicle 100 and is located on the straddle section on the side of the transmission assembly 14. A second exhaust channel is formed inside the all-terrain vehicle 100, flowing from the front of the frame 12, through the inside of the second heat shield 2374, and extending to the rear of the frame 12. As one implementation, the second heat shield 2374 and the first heat shield 2373 are basically the same in structure, shape, and material, and will not be described in detail here. During the operation of the all-terrain vehicle 100, ambient air entering from the front of the frame body 121 flows through the first exhaust channel and the first heat shield 2373, carrying away the heat trapped between the engine 111 and the first heat shield 2373. Air then flows through the second exhaust channel and the second heat shield 2374, carrying away the heat between the transmission assembly 14 and the second heat shield 2374. This reduces the heat transferred from the power system 11 to the riding position from the side of the frame 12, thereby reducing the heat transferred to the user's legs, effectively lowering the user's leg temperature and improving driving comfort. The second heat shield 2374 also has a heat insulation section 2374a, which isolates heat from the interior of the all-terrain vehicle 100. As one implementation, the heat insulation section 2374a is made of a material including aluminum foil and ceramic fibers. In this invention, the first heat insulation cover 2373 and the second heat insulation cover 2374 are respectively enclosed and covered on both sides of the all-terrain vehicle 100, isolating the inside and outside of the all-terrain vehicle 100 in the left-right direction. This allows the heat dissipation duct inside the all-terrain vehicle 100 to extend from the front to the rear. This arrangement effectively improves the ventilation efficiency inside the all-terrain vehicle 100 and also effectively reduces the noise of the engine 111 during startup or driving. The heat dissipation duct refers to the exhaust duct formed by the first exhaust passage and the second exhaust passage.
[0055] like 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 body panel 23 also includes a fuel tank guard plate 238. The fuel tank guard plate 238 is positioned above the fuel tank 132 and serves to protect the fuel tank 132. A fixing part 2381 is provided on the side of the fuel tank guard plate 238 closest to the fuel tank 132. The fuel tank guard plate 238 is connected to the first mudguard 231 via the fixing part 2381, and also connected to the side cover assembly 237 via the fixing part 2381. In the left-right direction of the all-terrain vehicle 100, one side of the fixing part 2381 is connected to the first side cover 2371, and the side of the fixing part 2381 away from the first side cover 2371 is connected to the second side cover 2372. The fixing part 2381 is located on the side of the fuel tank guard plate 238 closest to the fuel tank 132, that is, in the vertical direction of the all-terrain vehicle 100, the fixing part 2381 is located below the fuel tank guard plate 238. The fixing part 2381 includes a bolt fixing end 2381a, a snap-fit end 2381b and a plug-in hole 2381c. The bolt fixing end 2381a includes a first bolt fixing end and a second bolt fixing end. In the longitudinal direction of the all-terrain vehicle 100, the first bolt fixing end is located at the front end of the fuel tank guard plate 238, and the second bolt fixing end is located at the rear end of the fuel tank guard plate 238. The bolt fixing end 2381a allows the fuel tank guard plate 238 to be connected to the first side cover 2371 by bolts. There is a space between the first bolt fixing end and the second bolt fixing end. The snap-fit end 2381b and the insertion hole 2381c are arranged at intervals within this space. The snap-fit end 2381b can snap into the first side cover 2371 to restrict the movement of the fuel tank guard plate 238 in the vertical direction. The insertion hole 2381c can also snap into the first side cover 2371, thereby restricting the movement of the fuel tank guard plate 238 in the horizontal and longitudinal directions, thus realizing the connection between the first side cover 2371 and the fuel tank guard plate 238. Similarly, the connection method between the second side cover 2372 and the fuel tank guard plate 238 is the same as that of the first side cover 2371, and will not be described again. This configuration, by connecting and fixing the fuel tank protector 238, the first side cover 2371, and the second side cover 2372 together before assembling them onto the all-terrain vehicle 100, reduces assembly steps, improves assembly efficiency, and facilitates integrated disassembly and installation. The first side cover 2371 and the second side cover 2372 are snapped into the mounting bracket assembly 24. The first side cover 2371 and the second mudguard 232 are fitted with a clearance fit, thus providing a handhold on each side of the all-terrain vehicle 100 for easy installation and removal. One end of the first side cover 2371 is snapped into the first heat insulation cover 2373, and one end of the second side cover 2372 is snapped into 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, overheating of the first side cover 2371 and the second side cover 2372 can cause discomfort to the user. Therefore, heat insulation plates are also provided on the inner side of the first side cover 2371 and the second side cover 2372. The heat insulation plates are used to insulate heat and reduce heat transfer. The heat insulation plates are made of multi-layer composite materials, and as one implementation method, the heat insulation plates are made of aluminum foil and ceramic fiber. In this embodiment, the fuel tank guard plate 238, the first side cover 2371, and the second side cover 2372 are disassembled and reassembled as a whole. The connection between the three is a detachable fixing structure, which facilitates repeated installation and disassembly. During disassembly, the user can use the gap between the first side cover 2371 or the second side cover 2372 to pull the first side cover 2371 or the second side cover 2372, thereby disconnecting the connection between the first side cover 2371 or the second side cover 2372 and the fuel tank guard plate 238. This tool-free disassembly and assembly method is simple, quick, and convenient for maintenance, greatly improving maintenance efficiency and significantly reducing time costs.
[0057] Typically, all-terrain vehicles (ATVs) have a ventilation screen at the front to draw in ambient air. Since ATVs usually operate in outdoor environments, debris such as weeds and leaves easily accumulate on the screen while the vehicle is in motion. In existing technologies, the ventilation screen and mudguards are integrated, which often increases the difficulty of cleaning the screen, making cleaning time-consuming and laborious. In this invention, as... Figure 18 As shown, the vehicle body panel 23 also includes a ventilation mesh 236. The ventilation mesh 236 is located at the front of the all-terrain vehicle 100 and is mounted on the first mudguard 231. The ventilation mesh 236 has a grid-like ventilation hole, and a connecting portion 2361 for connecting to the first mudguard 231 is provided on the inner side of the ventilation mesh 236. The inner side of the ventilation mesh 236 refers to the side of the ventilation mesh 236 closest to the first mudguard 231. Connecting portions 2361 are provided around the perimeter of the ventilation mesh 236, and the connecting portions 2361 can engage with the first mudguard 231. 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 located at the upper end of the ventilation net 236, the second connecting portion 2361b is located at the bottom end of the ventilation net 236, the third connecting portion 2361c is located on the left side of the ventilation net 236, and the fourth connecting portion 2361d is located on the right side of the ventilation net 236. As one implementation, the first connecting portion 2361a engages with one end of the first mudguard 231, thus restricting the movement of the ventilation net 236 in the left-right and up-down directions. The second connecting portion 2361b engages with the end of the first mudguard 231 away from the first connecting portion 2361a, thus restricting the movement of the ventilation net 236 in the front-back direction. The third connecting part 2361c engages with one side of the first mudguard 231, and the fourth connecting part 2361d engages with the side of the first mudguard 231 away from the third connecting part 2361c. The third connecting part 2361c and the fourth connecting part 2361d can restrict the movement of the ventilation net 236 in the vertical and horizontal directions. This invention, by having the connecting parts 2361 arranged around the ventilation net 236 cooperate with the first mudguard 231, limits and fixes the ventilation net 236 in all directions, making the installation of the ventilation net 236 more secure and reliable. In this embodiment, the fixing method of each connecting part 2361 on the ventilation net 236 is a detachable fixing method, greatly simplifying the disassembly and assembly process. Users can disassemble and assemble the ventilation net 236 by hand without the need for tools, making the ventilation net 236 easy to clean. Furthermore, the ventilation net 236 of this invention can adapt to multiple installations and disassemblies and is not easily deformed.
