Technical Field

[0003] The present invention relates to the technical field of vehicles, and in particular to an all-terrain vehicle. Background Art

[0004] All-terrain vehicles (ATVs) are vehicles capable of traversing all terrains. They feature a high chassis, a suspension with excellent shock absorption, tires with good grip, and high power. With the rapid development of vehicle technology, ATVs are becoming increasingly popular among consumers. Compared to ordinary vehicles, ATVs can navigate extremely harsh environments, including but not limited to beaches, mountains, forests, and swamps. They are widely used on farms and in recreational areas.

[0005] Due to the complex terrain conditions in the wild, all-terrain vehicles require strong power output during the operation. This power requirement directly leads to an increase in the number of cylinders in the all-terrain vehicle, which increases the output power and heat generation. As a result, the temperature of the parts of the vehicle close to the driver's body, especially the legs, will be higher, thus reducing the driving experience. Summary of the Invention

[0060] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings, but these embodiments do not limit the present invention. Structural, methodological, or functional changes made by ordinary technicians in this field based on these embodiments are all included in the scope of protection of the present invention.

[0061] As shown in Figures 1 to 3, the present application provides an all-terrain vehicle (ATV). The ATV 100 includes a frame 11, a body panel 12, a running system 13, a suspension system 14, a powertrain 15, a transmission assembly 16, a fuel assembly 17, a seat assembly 19, a steering assembly 20, an electrical assembly 22, and a footrest assembly 27. The frame 11 forms the basic structure of the ATV. The body panel 12 is at least partially disposed on the frame 11 and surrounds the frame 11 to form a receiving space 115. The powertrain 15 includes an engine 151, which is at least partially disposed within the receiving space 115. The suspension system 14 is at least partially connected to the frame 11, and the running system 13 is connected to the frame 11 via the suspension system 14. The transmission assembly 16 is also in driving connection with the engine 151 and can transmit power from the engine 151 to the running system 13. The fuel assembly 17 is supported by the frame 11. The seat assembly 19 is provided for the user to ride, and the footrest assembly 27 is disposed below the seat assembly 19. The steering assembly 20 is operable to achieve steering of the all-terrain vehicle 100. In order to clearly define the technical solution of the present application, front, rear, up, down, left, and right are also defined as shown in Figure 1, wherein the front-to-back direction is the length direction of the frame 11, the left-to-right direction is the width direction of the frame 11, and the up-down direction is the height direction of the frame 11. A plane perpendicular to the height direction of the all-terrain vehicle 100 and passing through at least one contact point of the walking system 13 with the horizontal plane is defined as a reference plane 102. A plane perpendicular to the length direction of the frame 11 and passing through the midpoint of the wheelbase of the all-terrain vehicle 100 is defined as a transverse center plane 105 of the all-terrain vehicle 100. A plane perpendicular to the width direction of the frame 11 and passing through the midpoint of the width of the all-terrain vehicle 100 is defined as a longitudinal center plane 10s of the all-terrain vehicle 100, and the seat assembly 19 spans the longitudinal center plane 10s.

[0062] As shown in Figures 2 to 4, the engine 151 provided in the embodiment of the present application includes a cylinder 1513 and a cylinder head 1514. The cylinder head 1514 is connected to the cylinder 1513. Along the height direction of the all-terrain vehicle 100, the cylinder head 1514 is connected to the cylinder 1513 and is located above the cylinder 1513. Along the width direction of the all-terrain vehicle 100, a plurality of cylinder heads 1514 are distributed along the width direction of the all-terrain vehicle 100. Along the front-to-back direction of the all-terrain vehicle 100, the cylinder head 1514 faces the rear of the all-terrain vehicle 100. It can be understood that in order to meet the power requirements of the all-terrain vehicle 100, one, two, three or more cylinder heads 1514 can be provided, and this is not limited here.

[0063] As shown in Figures 9 to 12, the powertrain 15 also includes a continuously variable transmission mechanism 152, an air filter 154, and a magneto 157. The continuously variable transmission mechanism 152 and the engine 151 are arranged along the width of the all-terrain vehicle 100. The continuously variable transmission mechanism 152 is located on the left side of the engine 151, and the magneto 157 is located on the right side of the engine 151. The air filter 154 is connected to the engine 151 so that it can supply air to the engine 151. The magneto 157 can be driven to generate electricity. The continuously variable transmission mechanism 152 is provided with a driving wheel 1521 and a driven wheel 1522. The driving wheel 1521 is in transmission connection with the driven wheel 1522. The driving wheel 1521 is located on the left side of the all-terrain vehicle 100.

[0064] Along the height of the frame 11, the air filter 154 is at least partially located between the powertrain 15 and the seat assembly 19. It can be located at least partially above the driven wheel 1522 and forward of the cylinder head 1514. Viewed along the width of the frame 111, the air filter 154 at least partially overlaps the driven wheel 1522 and does not overlap with the engine 151 or the fuel tank 171. Along the length of the frame 11, the air filter 154 is at least partially located between the fuel tank 171 and the engine 151 (see FIG. 2 ). Viewed along the length of the frame 11, the air filter 154 at least partially overlaps the engine 151 and the fuel tank 171. Viewed along the height of the frame 11, the air filter 154 does not overlap with the cylinder head 1514 or the fuel tank 171. Through the above arrangement, the cylinder head 1514 is arranged obliquely rearward relative to the cylinder 1513, which can increase the layout space in front of the cylinder 1513, which is beneficial to the arrangement of the air filter 154 and can make the arrangement between the engine 151 and the air filter 154 more compact.

[0065] As shown in Figures 2 to 5, the vehicle frame 11 includes a main frame 113, which includes an upper main beam 1131, a lower main beam 1132, a crossbeam 1134, and a longitudinal beam 1133 disposed between the upper main beam 1131 and the lower main beam 1132. The longitudinal beam 1133 connects the upper main beam 1131 and the lower main beam 1132 along the height direction of the all-terrain vehicle 100. The upper main beam 1131 includes a left upper main beam 1131a and a right upper main beam 1131b, and the lower main beam 1132 includes a left lower main beam 1132a and a right lower main beam 1132b. The left upper main beam 1131a, the right upper main beam 1131b, the left lower main beam 1132a, and the right lower main beam 1132b each extend along the length direction of the all-terrain vehicle 100. The left upper main beam 1131a and the right upper main beam 1131b are substantially symmetrically arranged about the longitudinal center plane 10s, and the left lower main beam 1132a and the right lower main beam 1132b are substantially symmetrically arranged about the longitudinal center plane 10s. Along the width direction of the vehicle frame 11, the left upper main beam 1131a and the right upper main beam 1131b are connected by a cross beam 1134, and the left lower main beam 1132a and the right lower main beam 1132b are connected by a cross beam 1134.

[0066] The longitudinal beams 1133 include a front longitudinal beam 1133a, a middle longitudinal beam 1133b, and a rear longitudinal beam 1133c. These beams extend along the height of the ATV 100 and are arranged sequentially along the length of the ATV 100. The main frame 113 also includes connecting posts 1135, which include a front connecting post 1135a and a rear connecting post 1135b. The front connecting post 1135a and the rear connecting post 1135b extend substantially along the height of the frame 11 and are used to connect the upper main beam 1131 and the lower main beam 1132. Along the length of the frame 11, the longitudinal beams 1133 are located between the front connecting post 1135a and the rear connecting post 1135b.

[0067] The steering assembly 20 includes a steering handle 201 and a steering tube 202. The steering handle 201 is connected to the top of the steering tube 202. The steering tube 202 extends substantially along the height direction of the vehicle frame 11. Along the length direction of the vehicle frame 11, the steering tube 202 is located between the front pillar 1135a and the center longitudinal beam 1133b.

[0068] As can be understood, the upper main beam 1131, lower main beam 1132, longitudinal beam 1133, and cross beam 1134 define a housing space 115, with the engine 151 and transmission assembly 16 at least partially located within this housing space 115. More specifically, the engine 151, air filter 154, and fuel tank 171 are largely located between the upper and lower main beams 1131 and 1132. The fuel tank 171 is located behind the front longitudinal beam 1133a and in front of the center longitudinal beam 1133b. The engine 151 and air filter 154 are both located behind the center longitudinal beam 1133b and in front of the rear longitudinal beam 1133c. This arrangement allows the engine 151, air filter 154, and fuel tank 171 to be optimally positioned within the space surrounded by the various components of the vehicle frame 11, providing better protection from the frame 11. Furthermore, their reasonable arrangement allows for greater space utilization. Regardless of whether the fuel tank 171 is full of fuel, the center of gravity of the all-terrain vehicle 100 is located between the front longitudinal beam 1133a and the rear longitudinal beam 1133c and between the upper main beam 1131 and the lower main beam 1132. This arrangement is beneficial to the center of gravity of the entire vehicle and helps improve the driving stability of the all-terrain vehicle 100.

[0069] As shown in Figures 3, 4, and 9, the running system 13 includes a rear wheel 133, and the suspension system 14 connects the rear wheel 133 to the frame 11. The powertrain 15 is at least partially disposed on the frame 11 and is in driving connection with the rear wheel 133 to drive the rear wheel 133. The all-terrain vehicle 100 also includes an exhaust assembly 32 for conveying and discharging exhaust gas generated by the powertrain 15.

[0070] The powertrain 15 includes an engine 151, which is in driving connection with the rear wheels 133 so that the engine 151 drives the rear wheels 133 to rotate. Specifically, the engine 151 includes an exhaust passage 1515, which is used to discharge exhaust gas generated when the engine 151 is running and transport the exhaust gas generated by the engine 151 to the exhaust assembly 32.

[0071] More specifically, the exhaust assembly 32 includes an exhaust pipe 321 and a muffler 322. The exhaust pipe 321 is used to transport exhaust gas, and the muffler 322 is used to reduce the noise generated when the exhaust pipe 321 transports the exhaust gas. The exhaust pipe 321 is connected to the exhaust duct 1515, and the muffler 322 is connected to the exhaust pipe 321.

[0072] In this embodiment, the opening of the exhaust duct 1515 is positioned rearward. This arrangement allows the exhaust pipe 321 connected to the exhaust duct 1515 to be routed directly rearward, thereby shortening the overall length of the exhaust pipe 321 and, in turn, reducing the cost of the exhaust pipe 321. Furthermore, this arrangement also helps reduce the space occupied by the exhaust pipe 321 within the ATV 100, thereby providing more space for other components. This ensures that the exhaust pipe 321 does not interfere with the assembly of other components, thereby improving the compactness of the ATV 100.

[0073] Furthermore, in the present application, the exhaust gas generated by the engine 151 contains a large amount of heat. Therefore, the above-described arrangement allows the exhaust pipe 321 to be arranged rearward and shortened, thereby shortening the exhaust gas flow path within the ATV 100 and, in turn, reducing the heat transfer of the exhaust gas within the ATV 100, thereby lowering the overall temperature of the ATV 100 and improving the driving comfort of the ATV 100. Furthermore, in the present application, the seat assembly 19 (see FIG. 6 ) is located in front of the exhaust duct 1515. Therefore, by arranging the exhaust pipe 321 rearward, the exhaust pipe 321 can be arranged away from the seat assembly 19, thereby reducing the heat transferred from the exhaust gas in the exhaust pipe 321 to the seat assembly 19, further improving the driving comfort of the ATV 100.

[0074] In this embodiment, the orthographic projection of the exhaust duct 1515 on a horizontal plane is exhaust projection 1515a, and the orthographic projection of the axis of the rear wheel 133 on a horizontal plane is rear axle projection line 133a. The minimum distance D14 between the exhaust projection 1515a and the rear axle projection line 133a ranges from 250 mm to 400 mm. Specifically, the minimum distance D14 between the exhaust projection 1515a and the rear axle projection line 133a ranges from 300 mm to 350 mm. More specifically, the minimum distance D14 between the exhaust projection 1515a and the rear axle projection line 133a is 325 mm. This arrangement prevents the exhaust duct 1515 from being too far rearward due to the minimum distance D14 between the exhaust projection 1515a and the rear axle projection line 133a being too small, thereby preventing the exhaust duct 1515 from being too far rearward and causing the engine 151 to be too far rearward. This prevents the engine 151 from interfering with the assembly of components located at the rear of the vehicle frame 11, thereby improving the operating stability of the components at the rear of the vehicle frame 11. Furthermore, this can prevent the minimum distance D14 between the exhaust projection 1515a and the rear axle projection line 133a from being too large, which would result in the need for an excessively long exhaust pipe 321. This can help shorten the overall length of the exhaust pipe 321, prevent the exhaust pipe 321 from interfering with the assembly of other components, and thereby improve the compactness of the structure of the exhaust pipe 321. Furthermore, this can prevent the excessive heat transfer of the exhaust gas within the ATV 100 due to an excessively long exhaust pipe 321, thereby helping to reduce the overall temperature of the ATV 100 and improve the driving comfort of the ATV 100.

[0075] In one embodiment, the exhaust pipe 321 extends rearward along the front-to-back direction of the vehicle frame 11 and is divided by the longitudinal center plane 10s. This arrangement allows the exhaust pipe 321 to be centrally located along the width of the ATV 100, thereby preventing the exhaust pipe 321 from being biased to one side and causing excessive temperatures at the location of the exhaust pipe 321. This allows for a gap between the exhaust pipe 321 and both sides of the ATV 100 along the width direction. This gap can partially block heat dissipated by the exhaust pipe 321, thereby helping to reduce the overall heat dissipation of the ATV 100. Furthermore, the centrally located exhaust pipe 321 also helps shorten the exhaust pipe 321's routing path within the ATV 100, thereby shortening the overall length of the exhaust pipe 321.

[0076] As an optional implementation, the length L6 of the exhaust pipe 321 along the length of the ATV 100 ranges from 350 mm to 600 mm. Specifically, the length L6 of the exhaust pipe 321 ranges from 400 mm to 550 mm. More specifically, the length L6 of the exhaust pipe 321 ranges from 450 mm to 500 mm. This configuration prevents the exhaust pipe 321 from being too long, which could interfere with the assembly of other components, thereby improving the structural compactness of the exhaust pipe 321. Furthermore, it prevents the exhaust pipe 321 from being too long, which could cause the exhaust gas in the exhaust pipe 321 to conduct excessive heat within the ATV 100, thereby reducing the overall temperature of the ATV 100 and improving the driving comfort of the ATV 100.

[0077] In one embodiment, the orthographic projection of the first main beam 1131a on a horizontal plane is the first main beam projection line, the orthographic projection of the second main beam 1131b on a horizontal plane is the second main beam projection line, and the orthographic projection of the exhaust pipe 321 on a horizontal plane is the exhaust pipe projection line. The exhaust pipe projection line is located between the first and second main beam projection lines. That is, when viewed from the height of the ATV, the exhaust pipe is located between the first and second main beams. This arrangement facilitates the central placement of the exhaust pipe 321 along the width of the ATV 100, thereby reducing the overall heat generation of the ATV 100. Furthermore, it prevents the exhaust pipe 321 from interfering with the installation of components outside the frame 11 due to its location outside the upper main beam 1131. Furthermore, it prevents the exhaust pipe 321 from being unable to protect the exhaust pipe 321 due to its location outside the upper main beam 1131, thereby improving the protection of the exhaust pipe 321 and increasing its service life.

[0078] In one embodiment, the suspension system 14 includes a swingarm 145 and a shock absorber 147. The swingarm 145 connects the rear wheel 133 to the vehicle frame 11. The shock absorber 147 is connected to the swingarm 145 and the vehicle frame 11 at both ends, respectively, so that the shock absorber 147 can provide cushioning for the swingarm 145. Specifically, when viewed across the width of the all-terrain vehicle 100, the shock absorber 147 at least partially overlaps with the exhaust pipe 321. This arrangement prevents interference between the exhaust pipe 321 and the shock absorber 147 during assembly. Furthermore, this arrangement prevents the exhaust pipe 321 from occupying the space above the shock absorber 147, thereby reducing the available space for the shock absorber 147. This facilitates the placement of a larger shock absorber 147, thereby improving its damping effect and, consequently, enhancing the comfort of the all-terrain vehicle 100.

[0079] As shown in FIG6 , as one embodiment, the body panel 12 includes a front fender 126 for blocking mud and water. The travel system 13 includes a front wheel 132 for driving and steering the all-terrain vehicle 100. The front fender 126 is at least partially located above the front wheel 132. Furthermore, the all-terrain vehicle 100 also includes a suspension system 14 that connects the front wheel 132 to the frame 11. The powertrain 15 includes an engine 151 that is at least partially disposed on the frame 11 and is in transmission connection with the front wheel 132, thereby enabling the engine 151 to provide power to the front wheel 132 to drive the engine 151 to rotate.

[0080] Specifically, the ATV 100 further includes a fuel assembly 17, which is supported by the frame 11. Fuel assembly 17 includes a fuel tank 171, which is used to supply power to the engine 151. More specifically, a first plane 10j, perpendicular to the length of the ATV 100 and passing through the rotation axis of the front wheel 132, and a second plane 10k, perpendicular to the height of the ATV 100 and passing through the rotation axis of the front wheel 132, are defined. The fuel tank 171 is located behind the first plane 10j and at least partially in front of the engine 151. The fuel tank 171 is located above the second plane 10k and at least partially below the front fender 126. This arrangement allows the fuel tank 171 to be located at the front of the frame 11, thereby allowing the fuel tank 171 and the engine 151 to be distributed along the length of the all-terrain vehicle 100. Specifically, the fuel tank 171 can be located in front of the engine 151, thereby balancing the weight of the engine 151 and thereby improving the stability of the all-terrain vehicle 100. Furthermore, since the fuel tank 171 is located in front of the engine 151, the center of gravity of the fuel tank 171 can be lowered, that is, the center of gravity of the fuel tank 171 can be brought closer to the second plane 10k, thereby lowering the center of gravity of the all-terrain vehicle 100 and improving the driving stability of the all-terrain vehicle 100. Moreover, the fuel tank 171 being located behind the first plane 10j can avoid interference between the installation of the fuel tank 171 and the components at the front of the frame 11, thereby facilitating improved working stability of the fuel tank 171 and the components at the front of the frame 11; and the fuel tank 171 being located above the second plane 10k can avoid interference between the fuel tank 171 and the frame 11, the front wheel 132, and the suspension system 14, thereby facilitating stable operation of the fuel tank 171, the front wheel 132, and the suspension system 14.

[0081] In addition, through the above-mentioned arrangement, the fuel tank 171 can be arranged in front of the engine 151, thereby providing arrangement space behind the engine 151, so as to avoid the exhaust pipe 321 (refer to Figure 3) needing to avoid the fuel tank 171 for arrangement at the rear part of the frame 11, which is conducive to the exhaust pipe 321 being arranged directly rearward behind the engine 151, so as to shorten the length of the exhaust pipe 321.

[0082] In one embodiment, the minimum distance between the fuel tank 171 and the first plane 10j along the length of the ATV 100 is a first distance D9. The distance between the rotational axis of the front wheel 132 and the rotational axis of the rear wheel 133 along the length of the ATV 100 is a wheelbase D10. The ratio of the first distance D9 to the wheelbase D10 ranges from 0.1 to 0.16. Specifically, the ratio of the first distance D9 to the wheelbase D10 ranges from 0.11 to 0.14. More specifically, the ratio of the first distance D9 to the wheelbase D10 is 0.13. This arrangement prevents the fuel tank 171 from being too far back due to the ratio of the first distance D9 to the wheelbase D10 being too large, thereby preventing the fuel tank 171 from being unable to balance the weight of the engine 151, thereby improving the stability of the ATV 100. It also prevents the fuel tank 171 from being too far back and interfering with the installation of other components, thereby improving the overall assembly coordination of the ATV 100 and enhancing the overall structural compactness of the ATV 100. Furthermore, it prevents the fuel tank 171 from being too far forward due to the ratio of the first distance D9 to the wheelbase D10 being too small, thereby preventing the fuel tank 171 from interfering with components on the front of the frame 11, thereby improving the operational stability of the ATV 100.

[0083] Furthermore, an excessively large ratio of the first distance D9 to the wheelbase D10 can be avoided, which would result in the fuel tank 171 being positioned too far rearward, and thus the engine 151 being positioned too far rearward. This prevents the engine 151 from interfering with the installation of components at the rear of the frame 11, thereby improving the assembly coordination of the components at the rear of the frame 11 and enhancing the structural compactness of the rear portion of the frame 11. Furthermore, an excessively small ratio of the first distance D9 to the wheelbase D10 can be avoided, which would result in the fuel tank 171 being positioned too far forward, thereby preventing the engine 151 from being positioned too far forward and thus causing the exhaust pipe 321 to be excessively long. This prevents an excessively long exhaust pipe 321 from interfering with the assembly of other components, thereby improving the assembly coordination of the components at the exhaust pipe 321. Furthermore, an excessively long exhaust pipe 321 can be avoided, which would result in the exhaust gas within the exhaust pipe 321 transferring excessive heat within the ATV 100, thereby reducing the overall temperature of the ATV 100 and enhancing the driving comfort of the ATV 100. At the same time, it can also prevent the fuel tank 171 from being too close to the front and interfering with the components at the front of the frame 11, thereby facilitating the assembly coordination of the front of the frame 11.

[0084] In one embodiment, the acute angle κ formed between the cylinder axis 10m and the second plane 10k is positioned rearward. Positioning the cylinder head 1514 rearward allows the entire engine 151 to be positioned rearward, thereby reserving space in front of the engine 151 for the fuel tank 171, facilitating its installation. Furthermore, the fuel tank 171 and the engine 151 can be distributed along the length of the ATV 100, allowing the fuel tank 171 to balance the weight of the engine 151, thereby improving the overall stability of the ATV 100.

[0085] In one embodiment, the minimum distance between the rotational axis of the engine 151 and the rear wheel 133 along the length of the ATV 100 is the rearward distance D11. The ratio of the first distance D9 to the rearward distance D11 ranges from 0.11 to 0.17. Specifically, the ratio of the first distance D9 to the rearward distance D11 ranges from 0.13 to 0.16. More specifically, the ratio of the first distance D9 to the rearward distance D11 is 0.14. This arrangement prevents an excessively large ratio of the first distance D9 to the rearward distance D11, which could cause the fuel tank 171 and engine 151 to be positioned too far rearward. This prevents the overall center of gravity of the ATV 100 from being too far rearward, thereby improving the stability of the ATV 100. It also prevents the fuel tank 171 and engine 151 from being too far rearward, which could interfere with the installation of other components, thereby improving the overall assembly coordination of the ATV 100. Secondly, this can also prevent the ratio of the first distance D9 to the rearward distance D11 from being too small, which could result in the fuel tank 171 and the engine 151 being positioned too far forward, thereby preventing the overall center of gravity of the ATV 100 from being too far forward, further improving the stability of the ATV 100. Furthermore, this can also prevent the fuel tank 171 and the engine 151 from being too far forward, which could result in them interfering with components on the front of the frame 11, thereby improving the operational stability of the ATV 100.

[0086] In one embodiment, the minimum distance between the fuel tank 171 and the second plane 10k along the height direction of the ATV 100 is a second distance D12. The ratio of the second distance D12 to the wheelbase D10 ranges from 0.09 to 0.15. Specifically, the ratio of the second distance D12 to the wheelbase D10 ranges from 0.11 to 0.14. More specifically, the ratio of the second distance D12 to the wheelbase D10 is 0.12. This arrangement avoids an excessively large ratio of the second distance D12 to the wheelbase D10, which could result in the fuel tank 171 being installed too high. This, in turn, helps lower the overall center of gravity of the ATV 100, thereby improving the stability of the ATV 100. Secondly, it is also possible to avoid the ratio of the second distance D12 to the wheelbase D10 being too small, which would cause the installation position of the fuel tank 171 to be too low, thereby preventing the fuel tank 171 from interfering with the installation of other components at the bottom of the all-terrain vehicle 100, thereby facilitating improvement of the overall assembly coordination of the all-terrain vehicle 100 and improving the overall structural compactness of the all-terrain vehicle 100.

[0087] In one embodiment, the suspension system 14 includes a front shock absorber 142 and a front rocker arm (not shown). The front rocker arm connects the front wheel 132 to the vehicle frame 11. The front shock absorber 142 is rotatably connected to the front rocker arm and the vehicle frame 11, thereby providing a buffer between the vehicle frame 11 and the front rocker arm. The fuel tank 171 is at least partially located behind the front shock absorber 142. This arrangement prevents the fuel tank 171 from interfering with the installation of the front shock absorber 142, thereby improving the assembly coordination of the fuel tank 171 and the front shock absorber 142 and enhancing the structural compactness of the fuel tank 171.

[0088] In one embodiment, the body panel 12 further includes a storage box assembly 1205, which is supported by the vehicle frame 11. Specifically, along the length of the ATV 100, the storage box assembly 1205 is at least partially located between the front fender 126 and the seat assembly 19, with the fuel tank 171 at least partially located below the storage box assembly 1205. In this embodiment, because the fuel tank 171 utilizes the space in front of the engine 151, the overall height of the fuel tank 171 is lowered, thereby reserving space above the fuel tank 171. This allows for the placement of a larger storage box assembly 1205 within this space, thereby enhancing the storage function of the storage box assembly 1205. Furthermore, by reserving space above the fuel tank 171, other components can be arranged within this space without increasing the overall size of the ATV 100, thereby improving the space utilization of the ATV 100.

[0089] As an embodiment, the fuel assembly 17 includes a fuel filler port 172 , which is in communication with the fuel tank 171 , so that the fuel tank 171 can be charged through the fuel filler port 172 . The fuel filler port 172 is located on the front fender 126 .

[0090] As an optional implementation, the fuel filler opening 172 extends generally along a predetermined straight line 10n. The orthographic projection of the predetermined straight line 10n onto the longitudinal center plane 10s is a first projection line, and the orthographic projection of the second plane 10k onto the longitudinal center plane 10s is an axial horizontal line. The angle θ formed between the first projection line and the axial horizontal line ranges from 20° to 90°. Specifically, the opening of the angle is positioned rearward. More specifically, the angle θ formed between the first projection line and the axial horizontal line ranges from 40° to 70°. This arrangement prevents excessive tilting of the fuel filler opening 172 due to a too small angle θ, thereby preventing excessive tilting of the fuel filler opening 172 and reducing refueling smoothness, thereby improving refueling efficiency. In addition, it is also possible to avoid the angle θ formed by the first projection line and the horizontal line of the axis being too large, which causes the opening of the angle to be set forward. Therefore, when the fuel gun refuels at the fuel port 172, it is possible to avoid interference between the fuel gun and the parts set in front of the all-terrain vehicle 100 (such as the front rack on the front fender 126, etc.), which is beneficial to improving the convenience of refueling at the fuel port 172.

[0091] As shown in Figures 7 and 8, the fuel tank 171 is provided with a first fixing portion 1711, a second fixing portion 1712, and a plug-in portion 1713. Specifically, the vehicle frame 11 includes a first pipe 11d located in front of the fuel tank 171, a second pipe 11e located behind the fuel tank 171, and a supporting crossbeam 11f located below the fuel tank 171. The first fixing portion 1711 is fixedly connected to the first pipe 11d, and the second fixing portion 1712 is fixedly connected to the second pipe 11e. In some embodiments, the first pipe 11d and the second pipe 11e are distributed on both sides of the fuel tank 171 along the length of the all-terrain vehicle 100. Thus, the first fixing portion 1711 and the second fixing portion 1712 can secure both sides of the fuel tank 171, thereby improving the stability of the fuel tank 171.

[0092] In this embodiment, the plug-in portion 1713 plugs into the support beam 11f. In some embodiments, the support beam 11f is provided with an inserting port 11fa configured to be clamped by the clamping portion. This arrangement allows the plug-in portion 1713 to be inserted into the support beam 11f to limit the installation position of the fuel tank 171, thereby simplifying the assembly process of the fuel tank 171 and improving its assembly efficiency. Furthermore, this arrangement further improves the stability of the connection between the fuel tank 171 and the vehicle frame 11.

[0093] As shown in Figures 9 to 12, the line connecting the orthographic projection of the central axis of the driving wheel 1521 on the longitudinal center plane 10s and the orthographic projection of the central axis of the driven wheel 1522 on the longitudinal center plane 10s is the projection line 152a. The cylinder 1513 extends in the direction of the cylinder axis 10m. The orthographic projection of the cylinder axis 10m on the longitudinal center plane 10s is the cylinder axis projection line. The angle α formed by the cylinder axis projection line and the projection line 152a is positioned toward the rear of the ATV 100. The angle α ranges from 35° to 75°. Specifically, the angle α formed by the cylinder axis projection line and the projection line 152a ranges from 40° to 70°. More specifically, the angle α formed by the cylinder axis projection line and the projection line 152a ranges from 45° to 65°. For example, in this embodiment, the angle α formed by the cylinder axis projection line and the projection line 152a is 64.7°. This arrangement facilitates direct rearward routing of the exhaust pipe 321, thereby shortening the overall length of the exhaust pipe 321. Furthermore, this arrangement prevents an excessively large angle α between the cylinder axis projection and the projection line 152a, which would increase the length of the exhaust pipe 321 and thus shorten the overall length of the exhaust pipe 321. Furthermore, this arrangement prevents an excessively small angle α between the cylinder axis projection and the projection line 152a, which would cause the cylinder head 1514 to face too far rearward, thereby preventing the cylinder head 1514 from interfering with the assembly of other components.

[0094] As shown in FIG. 15 and FIG. 16 , the heat dissipation assembly 25 includes a heat dissipation pipe 253 . The heat dissipation pipe 253 is used to guide air outside the ATV 100 to the continuously variable transmission mechanism 152 , thereby cooling and dissipating heat for the continuously variable transmission mechanism 152 .

[0095] Specifically, the heat dissipation duct 253 includes an air inlet 2531 and an air outlet 2532. The heat dissipation duct 253 is configured to deliver external air to the continuously variable transmission mechanism 152 through the air inlet 2531 and the air outlet 2532. The vehicle body panel 12 includes a front fender 126. The wheels 13 include a front wheel 131. The front fender 126 is located above the front wheel 131 and, when viewed along the height of the vehicle frame 11, at least partially overlaps the front wheel 131. The front fender 126 is used to block mud, sand, gravel, and the like. The air inlet 2531 is mounted on the front fender 126, and external air enters the heat dissipation duct 253 through the air inlet 2531. The air outlet 2532 is arranged toward the continuously variable transmission mechanism 152 . The air entering the heat dissipation duct 253 from the air inlet 2531 is discharged from the air outlet 2532 and reaches the continuously variable transmission mechanism 152 .

[0096] Because the CVT mechanism 152 generates a large amount of heat during operation, which can cause the CVT mechanism 152 to overheat, and the existing cooling and heat dissipation structure is insufficient to cool the CVT mechanism 152, a heat dissipation duct 253 is added to improve the cooling and heat dissipation of the CVT mechanism 152. External air is transported to the CVT mechanism 152 through the heat dissipation duct 253, dissipating the heat from the CVT mechanism 152. This improves the cooling and heat dissipation of the CVT mechanism 152, thereby reducing the temperature of the entire ATV 100.

[0097] As an implementation method, the opening of the air inlet 2531 is generally arranged forward. Since airflow is generated from front to rear around the all-terrain vehicle 100 when it is traveling, the opening of the air inlet 2531 is generally arranged forward. This allows external air to smoothly enter the heat dissipation duct 253 through the air inlet 2531, and form an airflow from the air inlet 2531 to the air outlet 2532 within the heat dissipation duct 253, thereby improving the cooling and heat dissipation effect of the continuously variable transmission mechanism 152.

[0098] In the present application, a filter structure is provided within the air inlet 2531 to prevent mud, sand, gravel, etc. from entering the heat dissipation duct 253, thereby preventing mud, sand, gravel, etc. from entering the continuously variable transmission mechanism 152 and causing collision and wear on the continuously variable transmission mechanism 152, thereby preventing damage to the continuously variable transmission mechanism 152. In the present application, the filter structure is a filter mesh, etc.

[0099] As one implementation, the all-terrain vehicle 100 includes a cargo box assembly 21, which includes a cargo box 211 and a front cargo box mounting plate 212 for mounting the cargo box 211. The front fender 126 has a mounting surface 1261. The front cargo box mounting plate 212 is mounted to the mounting surface 1261 with a gap 254 therebetween. An air intake 2531 is located within the gap 254. This arrangement allows external air to enter the air intake 2531 through the gap 254 between the front cargo box mounting plate 212 and the mounting surface 1261 of the front fender 126. The placement of the air intake 2531 within the gap 254 prevents most mud, sand, and gravel from entering the heat dissipation duct 253. This prevents mud, sand, and gravel from entering the continuously variable transmission mechanism 152, potentially causing collision and wear, and thus preventing damage to the continuously variable transmission mechanism 152. At the same time, the air inlet 2531 is disposed within the gap 254, allowing external air to enter the air inlet 2531 through the gap 254, thereby not affecting the air intake effect of the heat dissipation duct 253. Furthermore, the above arrangement allows the air inlet 2531 to be arranged in the gap 254, thereby making the structure of the ATV 100 more compact and improving the space utilization of the ATV 100.

[0100] As an implementation, the powertrain 15 further includes a transmission air intake duct 153. This duct communicates with the continuously variable transmission mechanism 152 and is used to draw air into the continuously variable transmission mechanism 152. When viewed across the width of the frame 11, the transmission air intake duct 153 at least partially overlaps with the heat dissipation duct 253, thereby preventing interference between the two ducts and improving the compactness of the internal structure of the ATV 100.

[0101] Specifically, the ATV 100 also includes a fuel assembly 17. Fuel assembly 17 includes a fuel tank 171 and a fuel filler port 172, which is connected to and located above fuel tank 171. Along the width of the vehicle frame 11, a heat dissipation duct 253 is at least partially located between the fuel filler port 172 and the transmission air intake duct 153. This arrangement of the heat dissipation duct 253 between the fuel filler port 172 and the transmission air intake duct 153 prevents interference between the heat dissipation duct 253, the fuel filler port 172, and the transmission air intake duct 153, and improves the compactness of the internal structure of the ATV 100.

[0102] More specifically, the heat dissipation duct 253 is at least partially bent to form a bent portion 2533a, which is configured to avoid the fuel filler port 172. The provision of the bent portion 2533a prevents interference between the heat dissipation duct 253 and the fuel filler port 172 and further improves the compactness of the internal structure of the ATV 100.

[0103] More specifically, the bent portion 2533a is fixedly connected to the frame 11, and the bent portion 2533a is fixedly connected to the frame 11 by welding or bolting, etc., so as to improve the stability of the heat dissipation pipe 253 during the driving process of the all-terrain vehicle 100.

[0104] As an implementation, the heat dissipation duct 253 includes an integrally formed circular tube portion 2533 and a flat tube portion 2534. The circular tube portion 2533 communicates with the air inlet 2531, while the flat tube portion 2534 communicates with the air outlet 2532. The flat tube portion 2534 is configured to reduce the thickness of the heat dissipation duct 253 along a predetermined direction. The predetermined direction can be any direction. The provision of the flat tube portion 2534 allows the heat dissipation duct 253 to pass through narrow gaps between internal structures of the ATV 100, thereby avoiding interference with the internal structures of the ATV 100 and fully utilizing the limited space within the ATV 100 to improve space efficiency.

[0105] It should be noted that the bending portion 2533a is located on the circular tube portion 2533 so that the internal channel at the bending portion 2533a will not be too narrow, thereby reducing the flow resistance of air in the heat dissipation pipe 253 and further improving the heat dissipation effect of the continuously variable transmission mechanism 152.

[0106] Specifically, along the width of the frame 11, the flat tube portion 2534 is at least partially located between the transmission air intake duct 153 and the frame 11. The thickness of the flat tube portion 2534 along the width of the frame 11 is less than its thickness along the height of the frame 11. The gap between the transmission air intake duct 153 and the frame 11 is relatively small. The provision of the flat tube portion 2534 allows the heat dissipation duct 253 to pass through the gap between the transmission air intake duct 153 and the frame 11 without interfering with the transmission air intake duct 153 or the frame 11. This effectively utilizes the limited space and improves the space efficiency within the ATV 100.

[0107] More specifically, the flat tube portion 2534 is fixedly connected to the vehicle frame 11 , and the flat tube portion 2534 and the vehicle frame 11 may be fixedly connected by welding or bolting, etc., to further improve the stability of the heat dissipation pipe 253 during the driving process of the all-terrain vehicle 100 .

[0108] As shown in Figures 17 to 19, the body cover 12 includes a lower guard plate 12h. Lower guard plate 12h is located below and fixedly connected to the frame 11, thereby protecting the lower portion of the ATV 100 from external impurities such as stones, mud, and water, which may damage the internal components of the ATV 100. Lower guard plate 12h is at least partially located below the powertrain 15 and is substantially perpendicular to the height of the frame 11. This ensures that lower guard plate 12h does not interfere with the installation of the powertrain 15, while further enhancing protection for the powertrain 15.

[0109] The lower guard plate 12h is provided with heat dissipation holes 12ha, which are arranged toward the power assembly 15. When viewed from the height direction of the frame 11, the heat dissipation holes 12ha at least partially overlap with the power assembly 15. Therefore, when the all-terrain vehicle 100 is traveling, external air can be transported to the top of the lower guard plate 12h through the heat dissipation holes 12ha, so that the external air can be transported to the power assembly 15, thereby improving the heat dissipation effect of the power assembly 15.

[0110] Specifically, the lower guard plate 12h defines a heat dissipation slot 12hb, with the opening of the heat dissipation slot 12hb facing downward. The heat dissipation slot 12hb has a generally convex front sidewall 12hc. The front sidewall 12hc includes a front end 12hr and a rear end 12hs. The rear end 12hs is taller than the front end 12hr. The front end 12hr is located at the opening of the heat dissipation slot 12hb, and the rear end 12hs is connected to the bottom of the heat dissipation slot 12hb. The bottom of the heat dissipation slot 12hb defines a heat dissipation hole 12ha. This arrangement allows external air to be transported from the front end 12hr of the front sidewall 12hc along the front sidewall 12hc to the rear end 12hs of the front sidewall 12hc, and then from the rear end 12hs of the front sidewall 12hc through the heat dissipation hole 12ha at the bottom of the heat dissipation slot 12hb to the powertrain 15, thereby dissipating heat from the powertrain 15. The convex curved front side wall 12hc can guide the external air, thereby increasing the air intake volume into the heat dissipation hole 12ha, so as to further improve the heat dissipation effect of the power assembly 15.

[0111] A predetermined straight line 12hd is defined as connecting the front end 12hr and the rear end 12hs. A plane perpendicular to the width of the frame 11 and passing through the midpoint of the width of the all-terrain vehicle 100 is defined as the longitudinal center plane 10s of the frame 11 (see FIG. 26 ). The orthographic projection of the predetermined straight line 12hd on the longitudinal center plane 10s is the sidewall line. The angle σ formed by the sidewall line with the horizontal plane ranges from 23° to 40°, with the opening of the angle facing rearward. Specifically, the angle σ formed by the sidewall line with the horizontal plane ranges from 26° to 36°. More specifically, the angle σ formed by the sidewall line with the horizontal plane is 33°.

[0112] This arrangement prevents the angle σ formed between the sidewalls and the horizontal plane from being too small, which could result in the front sidewall 12hc being too long along the length of the frame 11. This, in turn, prevents the excessive length of the front sidewall 12hc from reducing the structural strength of the lower guard plate 12h. It also prevents air leakage from the excessive length of the front sidewall 12hc, thereby improving the heat dissipation effect of the heat dissipation holes 12ha on the powertrain 15. Furthermore, this arrangement prevents the angle σ formed between the sidewalls and the horizontal plane from being too large, which could result in the lower guard plate 12h being too thick along the height of the frame 11. This prevents the lower guard plate 12h from interfering with internal components of the all-terrain vehicle 100.

[0113] As an implementation, the heat sink 12hb includes a first side wall 12he and a second side wall 12hf extending along the width of the vehicle frame 11. An air intake passage 12hg is formed around the first side wall 12he, the second side wall 12hf, and the front side wall 12hc. The air intake passage 12hg is configured to convey ambient air into the heat dissipation holes 12ha. This arrangement confines ambient air within the air intake passage 12hg, preventing it from escaping. This increases the amount of air entering the heat dissipation holes 12ha and, in turn, improves heat dissipation for the powertrain 15.

[0114] Specifically, the heat sink 12hb has a rear sidewall 12hj for sealing the rear of the air intake passage 12hg. The rear sidewall 12hj is configured to prevent outside air from escaping from the air intake passage 12hg. Furthermore, this arrangement allows outside air to be blocked by the rear sidewall 12hj, allowing outside air to flow into the heat dissipation holes 12ha.

[0115] In this application, the bottom of the heat sink 12hb is provided with a grille structure 12hk, and the gaps between the grille structures 12hk form heat dissipation holes 12ha. The grille structure 12hk is used to prevent external impurities such as stones, mud and water from entering the upper part of the lower guard plate 12h, thereby preventing external impurities from damaging the powertrain 15 and the like.

[0116] In one embodiment, the lower guard plate 12h includes a first guard plate 12hm and a second guard plate 12hn located behind the first guard plate 12hm. The second guard plate 12hn is at least partially located below the powertrain 15. Both the first guard plate 12hm and the second guard plate 12hn are provided with heat dissipation slots 12hb and heat dissipation holes 12ha. The separate lower guard plate 12h can be adjusted according to assembly requirements, thereby facilitating assembly of the lower guard plate 12h.

[0117] Specifically, the powertrain 15 includes a continuously variable transmission mechanism 152 and an engine 151. The heat dissipation holes 12ha of the first guard plate 12hm are set toward the engine 151, and the heat dissipation holes 12ha of the second guard plate 12hn are set toward the continuously variable transmission mechanism 152, so that the heat dissipation holes 12ha on the first guard plate 12hm can dissipate heat to the engine 151, and the heat dissipation holes 12ha on the second guard plate 12hn can dissipate heat to the continuously variable transmission mechanism 152.

[0118] In this embodiment, the heat dissipation groove 12hb includes a first heat dissipation groove 12hp, the first guard plate 12hm includes multiple first heat dissipation grooves 12hp, the multiple first heat dissipation grooves 12hp are distributed along the width direction of the frame 11, and the heat dissipation holes 12ha on the multiple first heat dissipation grooves 12hp are all set toward the engine 151 to improve the heat dissipation efficiency of the engine 151.

[0119] In this embodiment, the continuously variable transmission mechanism 152 and the engine 151 are arranged along the width of the vehicle frame 11. The heat dissipation slots 12hb include a second heat dissipation slot 12hq. At least one second heat dissipation slot 12hq is provided on the second guard plate 12hn. When viewed from the height of the vehicle frame 11, the heat dissipation holes 12ha in each second heat dissipation slot 12hq at least partially overlap with the continuously variable transmission mechanism 152. This allows the second heat dissipation slots 12hq to better transport external air to the continuously variable transmission mechanism 152 through the heat dissipation holes 12ha, thereby improving the heat dissipation efficiency of the continuously variable transmission mechanism 152.

[0120] As shown in Figures 21 and 22, the vehicle body panel 12 also includes a left side cover 1206 and a right side cover 1207. Specifically, the storage box assembly 1205, the left side cover 1206, and the right side cover 1207 are all at least partially supported by the vehicle frame 11. Along the length of the vehicle frame 11, the storage box assembly 1205, the left side cover 1206, and the right side cover 1207 are at least partially located between the front fender 126 and the seat assembly 19. The left side cover 1206 and the right side cover 1207 are located on either side of the storage box assembly 1205 along the width of the vehicle frame 11. The left side cover 1206 and the front fender 126 define a first space 1206a, while the right side cover 1207 and the front fender 126 define a second space 1207a. This arrangement provides space for component placement, thereby improving space utilization at the left and right side covers 1206 and 1207.

[0121] More specifically, the storage box assembly 1205 is at least partially located within the first space 1206a and / or the second space 1207a. This arrangement allows the storage box assembly 1205 to utilize the space provided by the first space 1206a and / or the second space 1207a, thereby increasing the space occupied by the storage box assembly 1205 and, in turn, increasing the storage capacity of the storage box assembly 1205, thereby improving the storage function of the all-terrain vehicle 100.

[0122] In this embodiment, the volume of the storage box assembly 1205 ranges from 6L to 10L. Specifically, the volume of the storage box assembly 1205 ranges from 7L to 9L. More specifically, the volume of the storage box assembly 1205 is 8L. This arrangement prevents the storage box assembly 1205 from interfering with other components within the first and second spaces 1206a, 1207a due to an excessively large volume range, thereby improving space utilization within the first and second spaces 1206a, 1207a. It also prevents the storage box assembly 1205 from being too small, thereby reducing the available storage space, thereby improving the storage capacity of the storage box assembly 1205.

[0123] As shown in FIG20 , as one embodiment, the powertrain 15 further includes an air filter intake duct 155 and a transmission intake duct 153. The air filter intake duct 155 is connected to the air filter 154 and is used to supply air to the air filter 154. The continuously variable transmission mechanism 152 is used to adjust the transmission ratio, and the transmission intake duct 153 is connected to the continuously variable transmission mechanism 152 and is used to supply air to the continuously variable transmission mechanism 152. Specifically, when viewed from the height of the vehicle frame 11, the glove box assembly 1205 at least partially overlaps with the air filter intake duct 155, and the glove box assembly 1205 at least partially overlaps with the transmission intake duct 153. This arrangement improves the structural compactness of the glove box assembly 1205.

[0124] In this embodiment, the air filter intake duct 155 and the transmission intake duct 153 are at least partially located below the storage box assembly 1205. This arrangement prevents the air filter intake duct 155 and the transmission intake duct 153 from interfering with the removal of items from the storage box assembly 1205, thereby improving the convenience of using the storage box assembly 1205.

[0125] As shown in Figures 20 and 21 , the maximum distance D8 between the left side cover 1206 and the right side cover 1207 along the width direction of the vehicle frame 11 is greater than the maximum width W1 of the seat assembly 19 along the width direction of the vehicle frame 11. This arrangement increases the volume of the first space 1206a and the second space 1207a, thereby facilitating the placement of a larger storage box assembly 1205 within the first space 1206a and / or the second space 1207a, thereby increasing the storage capacity of the storage box assembly 1205.

[0126] In one embodiment, the storage box assembly 1205 includes an upper box body 1205a and a lower box body 1205b, with the upper box body 1205a and the lower box body 1205b being fixedly connected. Specifically, the upper box body 1205a is provided with a storage opening 1205c. This arrangement allows items to be stored and retrieved from the storage box assembly 1205 through the storage opening 1205c. More specifically, both the upper box body 1205a and the lower box body 1205b are at least partially located within the first space 1206a and / or the second space 1207a. When viewed from the height of the vehicle frame 11, the storage opening 1205c does not overlap with the first space 1206a, and the storage opening 1205c does not overlap with the second space 1207a. This arrangement can prevent the left cover 1206 at the first space 1206a and the right cover 1207 at the second space 1207a from interfering with taking items from the storage opening 1205c, thereby improving the convenience of using the storage box assembly 1205.

[0127] Furthermore, by separating the storage box assembly 1205 into an upper box body 1205a and a lower box body 1205b, storage spaces can be separately fabricated within the upper box body 1205a and the lower box body 1205b. This avoids the problem of a monolithic structure preventing the inability to create a large storage space within the storage box assembly 1205. This arrangement simplifies the fabrication process for the storage space within the storage box assembly 1205 while also increasing the volume of the storage space within the storage box assembly 1205.

[0128] As shown in Figure 21, the lower case 1205b is provided with a first through hole 1205d and a second through hole 1205e, which are located at the front of the lower case 1205b. The first through hole 1205d is used to fix the cigarette lighter, and the second through hole 1205e is used to fix the USB connector.

[0129] As shown in Figures 21 and 22, storage box assembly 1205 includes a storage cover 1205f, which is rotatably connected to upper case 1205a and configured to cover storage opening 1205c. This arrangement allows storage cover 1205f to shield storage opening 1205c, preventing items within storage box assembly 1205 from falling through storage opening 1205c during travel of ATV 100, thereby improving storage security of storage box assembly 1205.

[0130] Specifically, one side of the storage cover 1205f has a rotation axis 1205g and an extension 1205h. The extension 1205h is generally U-shaped, with the rotation axis 1205g located at the end of the extension 1205h away from the storage cover 1205f. The rotation axis 1205g is rotatably connected to the upper case 1205a. This arrangement allows the storage cover 1205f to be opened and closed by rotating the rotation axis 1205g. Furthermore, the U-shaped extension 1205h prevents interference between the extension 1205h and other components during rotation, allowing the storage cover 1205f to open and close normally.

[0131] More specifically, the side of the storage cover 1205f away from the extension 1205h has a cover connection portion 1205i. The lower box 1205b at least partially extends upward to form a fixing boss 1205j. The fixing boss 1205j is located at the rear of the lower box 1205b. The cover connection portion 1205i can be inserted through the fixing boss 1205j and engage with the fixing boss 1205j. This arrangement facilitates the opening and closing of the storage cover 1205f and the upper box 1205a, thereby improving the ease of use of the storage box assembly 1205.

[0132] As an optional implementation, a limiting portion 1205k is provided on the extension portion 1205h, and the limiting portion 1205k is configured to limit the rotation angle of the storage cover 1205f relative to the upper box body 1205a, thereby preventing the storage cover 1205f from rotating too much and causing interference between the storage cover 1205f and other components on the all-terrain vehicle 100.

[0133] Specifically, when storage cover 1205f covers storage opening 1205c, its two sides along the width of frame 11 can respectively fit over left cover 1206 and right cover 1207 (see FIG20 ). This arrangement improves the smoothness of storage cover 1205f, left cover 1206, and right cover 1207, thereby enhancing driving comfort on frame 11. Furthermore, it helps reduce wind resistance at storage cover 1205f, thereby reducing wind resistance of ATV 100 and, in turn, energy consumption of ATV 100.

[0134] As shown in Figure 21, the glove box assembly 1205 is at least partially located within the first space 1206a. The ATV 100 also includes a shift assembly 18, which is at least partially located within the second space 1207a and connected to the right side cover 1207. This arrangement prevents interference between the glove box assembly 1205 and the shift assembly 18, and also helps improve the space utilization of the first and second spaces 1206a, 1207a, thereby enhancing the compactness of the structures within the first and second spaces 1206a, 1207a. Specifically, the shift assembly 18 is configured as an electronic shifter 181. This electronic shifter 181 can increase shift response speed, thereby improving the handling performance of the ATV 100.

[0135] As an optional implementation, the shift assembly 18 is snap-fitted to the right side cover 1207 and fixedly connected via fasteners. This arrangement improves the installation stability of the shift assembly 18 within the second space 1207a. Furthermore, the shift assembly 18 is fixedly connected to the glove box assembly 1205. This arrangement further improves the installation stability of the shift assembly 18 within the second space 1207a.

[0136] Specifically, a mounting post 1205m is formed upwardly, at least partially, on one side of the storage box assembly 1205 near the right side cover 1207. This post is threaded through the shift assembly 18 and fixedly connected to the mounting post 1205m via a fastener. In some embodiments, a mounting post 1205m is formed upwardly, at least partially, on one side of the upper case 1205a near the right side cover 1207. The mounting post 1205m is a boss post, and the fastener is a screw. This arrangement allows the screw to thread through the shift assembly 18 and connect to the boss post, thereby securing the shift assembly 18 to the upper case 1205a and improving the stability of the connection between the shift assembly 18 and the upper case 1205a.

[0137] As shown in Figures 24, 25, and 29, the body panel 12 also includes a radiator grille 12f and a side cover 12g. The side cover 12g is supported by the vehicle frame 11 and serves as an exterior feature of the all-terrain vehicle 100, protecting the internal components of the vehicle 100. Specifically, along the length of the vehicle frame 11, the side covers 12g are at least partially positioned between the front fender 126 and the seat assembly 19. The radiator grille 12f is mounted at the front end of the side cover 12g. An air intake duct 12ga is formed at least partially around the side cover 12g. The radiator grille 12f communicates with the air intake duct 12ga. The air intake duct 12ga has at least one air inlet (not shown) and one air outlet (not shown). The air inlet opens toward the radiator grille 12f, and the air outlet opens toward the powertrain 15. Observing along the length of the vehicle frame 11, at least a portion of the radiator grille 12f is visible. The outermost portion of the air intake duct 12ga is located closer to the longitudinal center plane 10s than the outermost portions of the left or right steering handlebars 2013 and 2014. This arrangement allows air to enter the air intake duct 12ga through the radiator grille 12f and flow toward the powertrain 15 through the air outlet during operation of the all-terrain vehicle 100. This improves the heat dissipation of the powertrain 15 and ensures stable operation. Furthermore, heat dissipation from the powertrain 15 helps lower the overall temperature of the all-terrain vehicle 100, thereby improving the perceived temperature of the driver and passengers and enhancing their comfort. Furthermore, this arrangement prevents damage to the powertrain 15 due to excessive temperatures, thereby increasing its service life.

[0138] More specifically, the radiator grille 12 f is at least partially located above the upper surface of the front fender 126 , so that the front fender 126 does not block the air intake of the radiator grille 12 f , thereby improving the heat dissipation effect of the powertrain 15 .

[0139] In this embodiment, the minimum distance between the radiator grille 12f and the rotation axis of the front wheel 131 along the height direction of the ATV 100 is a first distance H1. The minimum distance between the rotation axis of the front wheel 131 and the reference plane 102 along the height direction of the frame 11 is a second distance H2. The ratio of the first distance H1 to the second distance H2 ranges from 1.5 to 2.4. Specifically, the ratio ranges from 1.7 to 2.2. More specifically, the ratio of the first distance H1 to the second distance H2 is 1.95. This arrangement prevents the first distance H1 from being too small, which could result in the front fender 126 blocking the radiator grille 12f, thereby improving the air intake efficiency of the radiator grille 12f. It also prevents the first distance H1 from being too small, which could result in the radiator grille 12f being located below the front fender 126. This prevents the front wheel 131 below the front fender 126 from splashing mud, water, and other impurities into the radiator grille 12f, thereby preventing impurities from striking the powertrain 15 and damaging it. This improves the heat dissipation efficiency and service life of the powertrain 15. Furthermore, this arrangement prevents the first distance H1 from being too large, which could increase the height of the frame 11, thereby improving the compactness of the ATV 100. It also prevents the first distance H1 from interfering with the steering system 20, thereby improving the operational stability of the radiator grille 12f and the steering system 20.

[0140] In one embodiment, the powertrain 15 is at least partially located below the seat assembly 19, and the air outlet is at least partially located below the air intake duct 12ga, so that the air outlet faces the powertrain 15. The seat assembly 19 is connected to the side cover 12g and is configured to seal the rear of the air intake duct 12ga, allowing air within the air intake duct 12ga to be delivered to the powertrain 15 through the air outlet below the air intake duct 12ga. This arrangement prevents air from escaping from the rear of the air intake duct 12ga, thereby improving the sealing performance of the air intake duct 12ga and, in turn, enhancing heat dissipation from the powertrain 15. Furthermore, sealing the air intake duct 12ga through the seat assembly 19 eliminates the need for additional components, simplifying the structure of the air intake duct 12ga and reducing the production cost of the all-terrain vehicle 100.

[0141] In one embodiment, the side cover 12g is provided with a mounting hole 12gc located at the front end of the side cover 12g. The radiator grille 12f is at least partially located within the mounting hole 12gc and is fixedly connected to the side cover 12g. This arrangement allows the mounting hole 12gc to face forward, thereby facilitating air flow through the mounting hole 12gc and into the air intake passage 12ga during travel of the all-terrain vehicle 100, thereby improving heat dissipation for the powertrain 15. In some embodiments, the radiator grille 12f is connected to the side cover 12g via screws, thereby enhancing the stability of the connection between the radiator grille 12f and the side cover 12g.

[0142] As an embodiment, the side cover 12g includes a left cover 12gd and a right cover 12ge. Both the left cover 12gd and the right cover 12ge are supported by the vehicle frame 11, and the left cover 12gd and the right cover 12ge are distributed along the width direction of the vehicle frame 11. Specifically, the radiator grille 12f is mounted on the front end of the left cover 12gd and / or the right cover 12ge. The left cover 12gd is surrounded by a first space, and the right cover 12ge is surrounded by a second space. The air intake duct 12ga is at least partially located within the first space and / or the second space. The radiator grille 12f is connected to the first space and / or the second space. With this arrangement, the position of the air intake duct 12ga can be flexibly adjusted according to assembly requirements, thereby preventing the air intake duct 12ga from interfering with the assembly of other components. When the air intake passage 12ga is located within the first and second spaces, insufficient air intake due to unilateral air intake of the air intake passage 12ga can be avoided, thereby facilitating increased air intake of the air intake passage 12ga and, in turn, improving heat dissipation for the powertrain 15. This arrangement allows the position of the air intake passage 12ga to be flexibly adjusted based on assembly requirements and the heat dissipation requirements of the powertrain 15, thereby facilitating increased assembly flexibility for the air intake passage 12ga.

[0143] As an optional implementation, the radiator grille 12f is provided with a plurality of heat dissipation shields 12fa, with heat dissipation holes 12fb formed between adjacent heat dissipation shields 12fa. This arrangement prevents flying rocks and gravel from entering the air intake passage 12ga through the mounting holes 12gc, thereby preventing damage to the powertrain 15 caused by such flying rocks and gravel, thereby improving the protection of the internal components of the all-terrain vehicle 100.

[0144] In this embodiment, at least part of the heat dissipation holes 12fb is arranged higher than the upper surface of the front fender 126. This arrangement can prevent the front fender 126 from blocking air from entering the air intake passage 12ga through the heat dissipation holes 12fb, thereby improving the air intake efficiency of the heat dissipation holes 12fb.

[0145] In one embodiment, the vehicle body panel includes an instrument panel cover 1204 for mounting the instrument panel. The instrument panel cover 1204 is mounted on the front fender 126, and the radiator grille 12f is located on at least one side of the instrument panel cover 1204 along the width of the vehicle frame 11. This arrangement prevents the instrument panel cover 1204 from obstructing air from entering the air intake passage 12ga through the radiator grille 12f, thereby improving the air intake efficiency of the radiator holes 12fb.

[0146] In one embodiment, the vehicle body panel further includes a storage compartment assembly 1205, which is used for storing items and is supported by the vehicle frame 11. Specifically, the storage compartment assembly 1205 is at least partially located within the first space and / or the second space. More specifically, the storage compartment assembly 1205 includes a storage cover 1205f. The cover 1205f's two sides along the width of the vehicle frame 11 are respectively adapted to fit over the left and right covers 12gd and 12ge, thereby sealing the upper portion of the intake duct 12ga. This arrangement creates a substantially sealed space within the intake duct 12ga, preventing air from leaking out of the intake duct 12ga and allowing air to flow through the intake duct 12ga and be delivered to the powertrain 15, thereby improving heat dissipation efficiency for the powertrain 15.

[0147] As shown in Figures 26 and 29, the steering system 20 includes a steering handle 201 for controlling the steering of the all-terrain vehicle 100. The steering handle 201 includes a left steering handle 2013 and a right steering handle 2014. The left steering handle 2013 and the right steering handle 2014 are distributed along the width direction of the frame 11, thereby facilitating the driver's control of the steering handle 201.

[0148] The body panel 12 includes two mounting plates 12ja, positioned below the front fender 126 and located on either side of the steering handlebar 201. The two mounting plates 12ja and the front fender 126 surround a left storage space and a right storage space, each opening toward the rear of the all-terrain vehicle 100. When viewed from the height of the vehicle frame 11, the left and right storage spaces are located below the left and right steering handlebars 2013 and 2014, respectively, at least partially overlapping them. This provides storage for the driver and / or passengers, and the positioning of the left and right storage spaces facilitates storage for the driver.

[0149] Specifically, the vehicle body covering 12 further includes two storage covers 12jb, which are respectively connected to the left storage space and the right storage space and can close the left storage space and the right storage space;

[0150] The upper end of the storage cover 12jb is engaged with the mounting plate 12ja, and the lower end of the storage cover 12jb is rotatably connected to the mounting plate 12ja.

[0151] As an implementation, when the mounting plate 12ja is provided, the air intake passage 12ga is at least partially located between the mounting plate 12ja and the longitudinal center plane 10s. When viewed along the height direction of the vehicle frame 11, the mounting plate 12ja is at least partially located below the left steering handle 2013 and / or below the right steering handle 2014, and the mounting plate 12ja at least partially overlaps the left steering handle 2013 and / or the right steering handle 2014.

[0152] As an implementation method, the air channel 12ga is at least partially located between the two mounting plates 12ja, so that the air intake channel 12ga will not interfere with the two mounting plates 12ja; and the air in the air intake channel 12ga will not leak from the two mounting plates 12ja, so as to improve the heat dissipation effect of the powertrain 15.

[0153] 29 and 30 , the ATV 100 further includes a lamp assembly 23 for providing lighting for the ATV 100. The lamp assembly 23 is supported by the vehicle frame 11 and / or the vehicle body panel 12 and includes a left headlamp 231 and a right headlamp 232.

[0154] The minimum distance between the leftmost end of the body panel 12 and the rightmost end of the left headlight 231 along the width of the frame 11 is a first distance D4, and the minimum distance between the rightmost end of the body panel 12 and the leftmost end of the right headlight 232 along the width of the frame 11 is a second distance D5. Both the first distance D4 and the second distance D5 range from 350 mm to 400 mm. Specifically, the first distance D4 and the second distance D5 range from 360 mm to 380 mm. More specifically, the first distance D4 and the second distance D5 are 370 mm. This arrangement reduces the width of the body panel 12 where the left and right headlights 231 and 232 are mounted, making the ATV 100 more compact. Furthermore, to meet the lighting requirements of the ATV, the first distance D4 and the second distance D5 should not be too large, thereby preventing the illumination range of the left and right headlights 231 and 232 from being too narrow, thereby improving the driving safety of the ATV 100. Therefore, through the above arrangement, the all-terrain vehicle 100 can meet the lighting requirements while having higher driving safety and a more compact structure.

[0155] As an implementation, the minimum distance between the left headlight 231 and the reference plane 102 along the height direction of the frame 11 is a first height H1, and the minimum distance between the right headlight 232 and the reference plane 102 along the height direction of the frame 11 is a second height H2. The first height H1 and the second height H2 both range from 660 mm to 990 mm. Specifically, the first height H1 and the second height H2 both range from 744 mm to 910 mm. More specifically, the first height H1 and the second height H2 both range from 785 mm to 870 mm. To meet the lighting requirements of the all-terrain vehicle, the first height H1 and the second height H2 should not be too small, thereby avoiding an excessively narrow illumination range of the left headlight 231 and the right headlight 232, thereby improving the driving safety of the all-terrain vehicle 100. Secondly, the first height H1 and the second height H2 should not be too large, otherwise they will shine into the eyes of pedestrians or other vehicle drivers, thereby avoiding safety accidents such as collisions between pedestrians or other vehicles and the ATV 100, thereby improving the driving safety of the ATV 100.

[0156] As one implementation, the body panel 12 includes an air intake grille 127 located in front of the vehicle frame 11. A left headlight 231 and a right headlight 232 are both located on the air intake grille 127. By locating the left and right headlights 231, 232 on the air intake grille 127, the width of the front end of the ATV 100 is shortened, thereby making the ATV 100 more compact. Furthermore, the left and right headlights 231, 232 can be mounted using the air intake grille 127, eliminating the need for additional mounting points for the left and right headlights 231, 232, further making the ATV 100 more compact.

[0157] Specifically, a transverse plane 106 perpendicular to the length of the vehicle frame 11 is defined. Along the length of the vehicle frame 11, the orthographic projection of the air intake grille 127 on transverse plane 106 is the grille projection. The orthographic projection of the left headlamp 231 on transverse plane 106 is the first lamp projection. The orthographic projection of the right headlamp 232 on transverse plane 106 is the second lamp projection. Both the first lamp projection and the second lamp projection are located within the grille projection. This arrangement further improves the compactness of the ATV 100.

[0158] More specifically, the ratio of the area of ​​the grille projection to the area of ​​the first lamp projection is in a range of 13 to 21; the ratio of the area of ​​the grille projection to the area of ​​the second lamp projection is in a range of 13 to 21. Specifically, the ratio of the area of ​​the grille projection to the area of ​​the first lamp projection is in a range of 15 to 19; the ratio of the area of ​​the grille projection to the area of ​​the second lamp projection is in a range of 15 to 19. More specifically, the ratio of the area of ​​the grille projection to the area of ​​the first lamp projection is 17; the ratio of the area of ​​the grille projection to the area of ​​the second lamp projection is 17. Through the above-mentioned setting, it is possible to avoid the projected area of ​​the first lamp and the projected area of ​​the second lamp being too large, thereby preventing the air intake effect of the air intake grille 127 from being affected; it is also possible to avoid the projected area of ​​the first lamp and the projected area of ​​the second lamp being too small, thereby preventing the left headlamp 231 and the right headlamp 232 from being too small, thereby preventing the left headlamp 231 and the right headlamp 232 from being too small, thereby preventing the lighting effects of the left headlamp 231 and the right headlamp 232 from being insufficient to meet the needs of the all-terrain vehicle 100, and thereby improving the driving safety of the all-terrain vehicle 100.

[0159] More specifically, the air intake grille 127 is provided with a plurality of mounting holes 1271, which are located behind the air intake grille 127. The left headlight 231 and the right headlight 232 are each provided with a mounting portion, which at least partially penetrates the air intake grille 127. The mounting portion is connected to the mounting hole 1271 via fasteners. The fasteners are bolts, etc. This arrangement facilitates the installation of the left headlight 231 and the right headlight 232 on the air intake grille 127, and reduces the size of the left headlight 231 and the right headlight 232, thereby facilitating miniaturization and lightweighting of the left headlight 231 and the right headlight 232, while also making the structure of the all-terrain vehicle 100 more compact.

[0160] As shown in FIG. 29 and FIG. 31 , the left headlamp 231 includes a low beam 233 and a high beam 234 . The low beam 233 is farther away from the right headlamp 232 than the high beam 234 .

[0161] The low beam headlight 233 includes a lamp mounting frame 2331, a light source 2332, a reflector bowl 2333, and a lens 2334. The light source 2332 is mounted on the lamp mounting frame 2331 and is capable of emitting light upward. The reflector bowl 2333 is at least partially located above the light source 2332 and is mounted on the lamp mounting frame 2331. The opening of the reflector bowl 2333 is at least partially oriented toward the light source 2332, and the reflector bowl 2333 is capable of reflecting light emitted by the light source 2332 forward. The lens 2334 is at least partially located in front of the reflector bowl 2333 and is capable of transmitting light reflected by the reflector bowl 2333 out of the low beam headlight 233. This arrangement allows the volume of the left and right headlights 231 and 232 to be reduced while meeting lighting requirements, thereby improving the structural compactness of the lamp assembly 23.

[0162] The arrows in Figure 31 indicate the direction of light emission. Light source 2332 emits light upward, and then reflector 2333 reflects the light emitted by light source 2332 forward. Finally, lens 2334 transmits the light reflected by reflector 2333 out of low beam headlight 233, thereby illuminating the front of ATV 100.

[0163] It should be noted that the structure of the high beam 234 is basically the same as that of the low beam 233, and the curvature of the lens 2334 of the high beam 234 is different from the curvature of the lens 2334 of the low beam 233, so that the lighting distances of the high beam 234 and the low beam 233 are different: the lighting distance of the high beam 234 is farther than that of the low beam 233.

[0164] It should be noted that the structure of the right headlight 232 is substantially identical to that of the left headlight 231 , so that when the low beam 233 or high beam 234 of the left and right headlights 231 and 232 are simultaneously turned on, the illumination range of the all-terrain vehicle 100 is substantially symmetrical.

[0165] Specifically, the width of the low beam 233 along the width of the frame 11 ranges from 30 mm to 40 mm, and the height of the low beam 233 along the height of the frame 11 ranges from 20 mm to 30 mm. The width of the high beam 234 along the width of the frame 11 ranges from 30 mm to 40 mm, and the height of the high beam 234 along the height of the frame 11 ranges from 20 mm to 30 mm. Specifically, the width of the low beam 233 along the width of the frame 11 is 35 mm, and the height of the low beam 233 along the height of the frame 11 is 25 mm. The high beam 234 along the width of the frame 11 is 35 mm, and the height of the high beam 234 along the height of the frame 11 is 25 mm. This configuration reduces the size of the left headlamp 231 and the right headlamp 232, facilitating miniaturization and lightweighting of the left and right headlamps 231 and 232, while also making the structure of the all-terrain vehicle 100 more compact.

[0166] As an implementation, the ATV 100 further includes a heat dissipation assembly 25, which is supported by the vehicle frame 11 and is used to dissipate heat for the powertrain 15 and other components. Specifically, the heat dissipation assembly 25 includes a radiator 201, which is used to dissipate heat for the powertrain 15 of the ATV 100. The radiator 201 is supported by the vehicle frame 11 and is at least partially located in front of the vehicle frame 11. Both the left headlight 231 and the right headlight 232 are at least partially located in front of the radiator 201. A transverse plane 106 perpendicular to the length of the vehicle frame 11 is defined. Along the length of the vehicle frame 11, the orthographic projection of the left headlight 231 on the transverse plane 106 is the headlight projection. The orthographic projection of the right headlight 232 on the transverse plane 106 has an area substantially equal to the headlight projection area. The orthographic projection of the radiator 201 on the transverse plane 106 is the heat dissipation projection, and the ratio of the headlamp projection area to the heat dissipation projection area ranges from 0.02 to 0.2. Because the headlamp projection and the heat dissipation projection partially overlap, the installation structure of the left and right headlamps 231 and 232 relative to the radiator 201 is more compact. Furthermore, this arrangement prevents the ratio of the headlamp projection area to the heat dissipation projection area from being excessively large, thereby preventing the left and right headlamps 231 and 232 from significantly impacting the air intake of the radiator 201. Therefore, this arrangement allows the ATV 100 to install the left and right headlamps 231 and 232 without affecting the heat dissipation efficiency of the radiator 201, saving installation space and making the ATV 100 more compact.

[0167] As shown in Figures 32 and 33, the lamp assembly 23 includes a position turn signal 235. The position turn signal 235 can provide a position signal indication of the ATV 100. When the position turn signal 235 is turned on, it indicates the presence and width of the ATV 100. The position turn signal 235 can also provide a turn signal indication of the ATV 100. The turn signal indication is that the position turn signal 235 turns on when the ATV 100 is turning to alert vehicles in front, behind, or on the left and right as well as pedestrians.

[0168] Specifically, the vehicle body panel 12 includes a lamp mounting member 129, which is supported by the vehicle frame 11. The lamp mounting member 129 is at least partially recessed to form a lamp mounting hole 1291. The position turn signal 235 is positioned within the lamp mounting hole 1291 and is fixedly connected to the lamp mounting member 129. By positioning the position turn signal 235 within the lamp mounting hole 1291, the position turn signal 235 is protected from direct impact by debris and the like, thereby preventing damage to the position turn signal 235 and increasing its service life.

[0169] As shown in Figures 34 and 35 , in this embodiment, the minimum distance D6 between the position turn signal lamp 235 and the opening of the lamp mounting hole 1291 along the length direction of the vehicle frame 11 ranges from 5 mm to 22 mm. Specifically, the minimum distance D6 between the position turn signal lamp 235 and the opening of the lamp mounting hole 1291 along the length direction of the vehicle frame 11 ranges from 10 mm to 17 mm. More specifically, the minimum distance D6 between the position turn signal lamp 235 and the opening of the lamp mounting hole 1291 along the length direction of the vehicle frame 11 is 13 mm. The above arrangement prevents the minimum distance D6 between the position turn signal lamp 235 and the opening of the lamp mounting hole 1291 along the length of the vehicle frame 11 from being too large, thereby preventing the light emitted by the position turn signal lamp 235 from being blocked by the lamp mounting member 129, which in turn reduces the signal indication effect of the position turn signal lamp 235 and reduces the driving safety of the all-terrain vehicle 100. Furthermore, the above arrangement prevents the minimum distance D6 between the position turn signal lamp 235 and the opening of the lamp mounting hole 1291 along the length of the vehicle frame 11 from being too small, thereby preventing the position turn signal lamp 235 from being directly hit by gravel or the like and causing damage, thereby increasing the service life of the position turn signal lamp 235. By setting the minimum distance D6 between the position turn signal lamp 235 and the opening of the lamp mounting hole 1291 along the length of the vehicle frame 11 within the above range, the position turn signal lamp 235 is protected while maintaining the emission of light from the position turn signal lamp 235.

[0170] Specifically, the position turn signal 235 includes a turn signal mounting frame 2351, a lamp bead 2352, a thick-walled member 2353, and a square lens 2354. The lamp bead 2352 is mounted on the turn signal mounting frame 2351, and the thick-walled member 2353 is mounted on the turn signal mounting frame 2351 and located in front of the lamp bead 2352. The square lens 2354 is located in front of the thick-walled member 2353. The square lens 2354 at least partially penetrates the turn signal mounting frame 2351 and is fixed to the turn signal mounting frame 2351. The square lens 2354 can transmit light from the lamp bead 2352 through the thick-walled member 2353 to the outside of the position turn signal 235. Specifically, the square lens 2354 is fixed to the turn signal mounting frame 2351 by snap-fitting. It should be noted that this application does not limit the method of fixing the square lens 2354 to the turn signal mounting frame 2351. Lamp bead 2352 emits light forward, which is then guided by thick-walled member 2353 to square lens 2354. Finally, square lens 2354 transmits the light directed by thick-walled member 2353 to the exterior of position turn signal lamp 235, thereby providing position and turn signal indications. This structural arrangement of position turn signal lamp 235 reduces its size, improving the compactness of ATV 100 and reducing the overall weight of ATV 100, thereby lowering the cost of ATV 100.

[0171] It should be noted that the lamp bead 2352 uses a two-color lamp bead 2352, so that the position turn signal light 235 can respectively realize the position signal indication function and the turn signal indication function.

[0172] As an implementation method, a tooth-like structure 2354a is provided on the side of the square lens 2354 away from the thick-walled part 2353. The tooth-like structure 2354a can refract the light of the lamp bead 2352 through the thick-walled part 2353 to the outside of the position turn signal 235, so that the light can be distributed according to the requirements of the position turn signal 235, and the luminous effect of the position turn signal 235 is improved, thereby improving the driving safety of the all-terrain vehicle 100.

[0173] As an implementation, the position turn signal light 235 further includes a lampshade 2355, which at least partially covers the front of the square lens 2354 and is connected to the turn signal light mounting frame 2351. The lampshade 2355 protects the internal structures of the position turn signal light 235, including the turn signal mounting frame 2351, the lamp beads 2352, the thick-walled member 2353, and the square lens 2354, thereby preventing damage to the position turn signal light 235 and increasing its service life.

[0174] As shown in FIG36 , a plurality of square lenses 2354 are provided, and the plurality of square lenses 2354 are arranged in a matrix, thereby making the structure of the plurality of square lenses 2354 more compact and being beneficial to improving the space utilization of the position turn signal lamp 235 .

[0175] Specifically, multiple lamp beads 2352 are provided. In one implementation, each lamp bead 2352 corresponds to multiple square lenses 2354, which helps reduce the cost of the position turn signal 235. In another implementation, each lamp bead 2352 corresponds to a square lens 2354, which can improve the lighting effect of the position turn signal 235 and thereby enhance the driving safety of the all-terrain vehicle 100. It should be noted that one or more lamp beads 2352 can be individually controlled to emit light, so that the position turn signal 235 can have a flowing light effect, thereby improving the recognition of the position turn signal 235 and thereby enhancing the driving safety of the all-terrain vehicle 100.

[0176] Specifically, the height of the square lens 2354 along the height direction of the frame 11 ranges from 5 mm to 6 mm, and the width of the square lens 2354 along the width direction of the frame 11 ranges from 5 mm to 6 mm. This configuration reduces the size of the position turn signal 235, thereby improving the compactness of the ATV 100 and reducing the weight of the ATV 100, thereby lowering the cost of the ATV 100.

[0177] Specifically, there are two position turn signals 235 and two lamp mounting holes 1291 . The two lamp mounting holes 1291 are distributed on the lamp mounting part 129 along the width direction of the vehicle frame 11 , and a position turn signal 235 is set in each lamp mounting hole 1291 .

[0178] As shown in FIG. 32 and FIG. 33 , the air intake grille 127 and the lamp mounting member 129 are integrally formed to facilitate the production of the body cover 12 of the all-terrain vehicle 100 , thereby helping to reduce the cost of the all-terrain vehicle 100 .

[0179] As shown in Figures 37 and 38, the lighting assembly 23 also includes a rear taillight 236 located at the rear of the vehicle frame 11. The body panel 12 also includes a taillight mounting bracket 12d located at the rear of the vehicle frame 11, and the rear taillight 236 is mounted on the taillight mounting bracket 12d. The rear taillight 236 is used to implement several of the following signal indication functions of the all-terrain vehicle 100: turn signal indication, position signal indication, brake signal indication, and reverse signal indication. The definitions of turn signal indication and position signal indication are the same as described above. The brake signal indication is: when the driver steps on the brake pedal, the rear taillight 236 will illuminate to warn the following vehicle to slow down or maintain a safe distance. The reverse signal indication is: when the all-terrain vehicle 100 is in reverse gear, the rear taillight 236 will illuminate to alert other vehicles and pedestrians.

[0180] As shown in FIG39 , the rear taillight 236 has a first mounting area 2361, a second mounting area 2362, and a third mounting area 2363. The first mounting area 2361 is at least partially located above the second mounting area 2362 and the third mounting area 2363. The second mounting area 2362 and the third mounting area 2363 are arranged along the width of the vehicle frame 11. The rear taillight 236 includes a first lamp module 2364, a second lamp module 2365, and a third lamp module 2366. The first lamp module 2364 is located in the first mounting area 2361, the second lamp module 2365 is located in the second mounting area 2362, and the third lamp module 2366 is located in the third mounting area 2363.

[0181] Define a transverse plane 106 perpendicular to the length of the frame 11. The orthographic projection of the first mounting area 2361 onto the transverse plane 106 along the length of the frame 11 is a first projection, the orthographic projection of the second mounting area 2362 onto the transverse plane 106 along the length of the frame 11 is a second projection, and the orthographic projection of the third mounting area 2363 onto the transverse plane 106 along the length of the frame 11 is a third projection. The ratio of the area of ​​the first projection to the area of ​​the second projection ranges from 2.1 to 3.2, and the ratio of the area of ​​the first projection to the area of ​​the third projection ranges from 2.4 to 3.6. Specifically, the ratio of the area of ​​the first projection to the area of ​​the second projection ranges from 2.3 to 3, and the ratio of the area of ​​the first projection to the area of ​​the third projection ranges from 2.7 to 3.3. More specifically, the ratio of the area of ​​the first projection to the area of ​​the second projection is 2.7, and the ratio of the area of ​​the first projection to the area of ​​the third projection is 3.

[0182] Through the above-mentioned setting, it is possible to avoid the ratio of the area of ​​the first projection to the area of ​​the second projection being too small, thereby avoiding the area of ​​the first lamp module 2364 being too small, resulting in reduced recognition of the first lamp module 2364, and thus increasing the danger of driving the all-terrain vehicle 100; it is also possible to avoid the ratio of the area of ​​the first projection to the area of ​​the second projection being too large, thereby avoiding the area of ​​the second lamp module 2365 being too small, resulting in reduced recognition of the second lamp module 2365, and thus increasing the danger of driving the all-terrain vehicle 100.

[0183] At the same time, the above setting can also avoid the ratio of the area of ​​the first projection to the area of ​​the third projection being too small, thereby avoiding the area of ​​the first lamp module 2364 being too small, resulting in reduced recognition of the first lamp module 2364, and thereby increasing the danger of driving the all-terrain vehicle 100; and can also avoid the ratio of the area of ​​the first projection to the area of ​​the third projection being too large, thereby avoiding the area of ​​the third lamp module 2366 being too small, resulting in reduced recognition of the third lamp module 2366, and thereby increasing the danger of driving the all-terrain vehicle 100.

[0184] Therefore, the present application sets the ratio of the first projection area of ​​the first installation area 2361 of the rear taillight 236 to the second projection area of ​​the second installation area 2362, and the ratio of the first projection area of ​​the first installation area 2361 to the third projection area of ​​the third installation area 2363 to the above-mentioned range, so that the first lamp module 2364 in the first installation area 2361, the second lamp module 2365 in the second installation area 2362, and the third lamp module 2366 in the third installation area 2363 all have better recognition, thereby improving the driving safety of the all-terrain vehicle 100.

[0185] Specifically, the first mounting area 2361 includes an upper mounting area 2361a and a lower mounting area 2361b. The upper mounting area 2361a is located above the lower mounting area 2361b, the second mounting area 2362, and the third mounting area 2363. The lower mounting area 2361b is located on the side of the second mounting area 2362 away from the third mounting area 2363 along the width direction of the vehicle frame 11. More specifically, the first lamp module 2364 is at least one of a position lamp and a brake lamp, the second lamp module 2365 is a turn lamp, and the third lamp module 2366 is a reverse lamp. The position lamp is used to provide the position signal indication function of the rear taillight 236, the brake lamp is used to provide the brake signal indication function of the rear taillight 236, the turn lamp is used to provide the turn signal indication function of the rear taillight 236, and the reverse lamp is used to provide the reverse signal indication function of the rear taillight 236. Through the above arrangement, the rear taillight 236 is partitioned and modularized so that the rear taillight 236 has multiple signal indication functions.

[0186] It should be noted that since the ATV 100 is not driven on highways or urban roads, the rear taillight 236 does not need to perform position signal indication functions or brake signal indication functions. Therefore, the first lamp module 2364 can be used only as a position light or only as a brake light. The first lamp module 2364 can also serve as both a position light and a brake light. When the first lamp module 2364 serves as both a position light and a brake light, the first lamp module 2364 uses dual-color LEDs to enable the first lamp module 2364 to perform both the position signal indication function and the brake signal indication function.

[0187] As shown in Figures 39 and 40, the first lamp module 2364 includes a plurality of first square lenses 2364a arranged in a matrix in a first mounting area 2361. The second lamp module 2365 includes a plurality of second square lenses 2365a arranged in a second mounting area 2362 along the width of the vehicle frame 11. The third lamp module 2366 includes a plurality of third triangular lenses 2366a arranged in a third mounting area 2363 along the width of the vehicle frame 11. The matrix arrangement of the plurality of first square lenses 2364a, the plurality of second square lenses 2365a, and the plurality of third triangular lenses 2366a makes the structure of the plurality of first square lenses 2364a, the plurality of second square lenses 2365a, and the plurality of third triangular lenses 2366a more compact, thereby improving the space utilization of the rear taillight 236.

[0188] As an implementation, the rear taillight 236 also includes a lamp mounting frame 2367, with the first mounting area 2361, the second mounting area 2362, and the third mounting area 2363 all located on the lamp mounting frame 2367. The first lamp module 2364 also includes a lamp bead 2364b and a thick-walled member 2364c. The lamp bead 2364b is mounted on the lamp mounting frame 2367, and the thick-walled member 2364c is mounted on the lamp mounting frame 2367 and located in front of the lamp bead 2364b. A first square lens 2364a is located in front of the thick-walled member 2364c. The first square lens 2364a at least partially penetrates the lamp mounting frame 2367 and is fixed to the lamp mounting frame 2367. The first square lens 2364a can transmit light from the lamp bead 2364b through the thick-walled member 2364c to the exterior of the first lamp module 2364. Specifically, the first square lens 2364a is fixedly engaged with the lamp mounting bracket 2367. It should be noted that the present application does not impose any restrictions on the fixing method of the first square lens 2364a and the lamp mounting bracket 2367. The lamp bead 2364b emits light forward, and then the thick-walled member 2364c guides the light to the first square lens 2364a. Finally, the first square lens 2364a transmits the light guided by the thick-walled member 2364c to the outside of the rear taillight 236 to realize the position signal and / or brake signal indication function of the rear taillight 236. Through the above-mentioned structural setting of the rear taillight 236, the volume of the rear taillight 236 can be reduced to improve the structural compactness of the all-terrain vehicle 100, and the weight of the entire all-terrain vehicle 100 can be reduced, which is conducive to reducing the cost of the all-terrain vehicle 100.

[0189] It should be noted that one or more lamp beads 2364b of the first lamp module 2364 can be individually controlled to emit light, so that the rear taillight 236 can have a flowing light effect, thereby improving the recognition of the rear taillight 236 and thereby improving the driving safety of the all-terrain vehicle 100.

[0190] As shown in Figures 40 and 41, a tooth-like structure 2364i is provided on the side of the first square lens 2364a away from the thick-walled part 2364c. The tooth-like structure 2364i can refract the light of the lamp bead 2364b through the thick-walled part 2364c to the outside of the first lamp module 2364, so that light distribution can be performed according to the needs of the first lamp module 2364, and the luminous effect of the first lamp module 2364 is improved, thereby improving the driving safety of the all-terrain vehicle 100.

[0191] Specifically, a plurality of lamp beads 2364b are provided. In one implementation, each lamp bead 2364b corresponds to a plurality of first square lenses 2364a, which helps reduce the cost of the first lamp module 2364. In another implementation, each lamp bead 2364b corresponds to a first square lens 2364a, which can improve the lighting effect of the first lamp module 2364 and thereby enhance the driving safety of the all-terrain vehicle 100.

[0192] It should be noted that the structure of the second lamp module 2365 is substantially the same as that of the first lamp module 2364 , and the structure of the third lamp module 2366 is substantially the same as that of the first lamp module 2364 .

[0193] As an implementation, the rear taillight 236 further includes a lampshade 2368, which at least partially covers the front of the first square lens 2364a, the second square lens 2365a, and the third square lens 2366a and is connected to the lamp mounting bracket 2367. The lampshade 2368 protects the internal structures of the rear taillight 236, such as the first lamp module 2364, the second lamp module 2365, and the third lamp module 2366, thereby preventing damage to the rear taillight 236 and increasing the service life of the rear taillight 236.

[0194] As shown in Figures 27 and 28, the lamp assembly 23 also includes multiple lamp controllers 239 that can communicate with each other. The two position turn signals 235, the two rear tail lights 236, the front position lights 237 and the rear position lights 238 are all electrically connected to a lamp controller 239, so that each of the above lamps can be controlled individually by a lamp controller 239, and the multiple lamp controllers 239 that communicate with each other can form an association between each of the above lamps, thereby enabling the above six lamps to achieve dynamic effects.

[0195] In this embodiment, each position turn signal 235 includes multiple lamp modules 230, and all lamp modules 230 are electrically connected to a lamp controller 239, so that the lamp controller 239 can control the multiple lamp modules 230 separately, so that the multiple lamp modules 230 can be linked, and thus the multiple lamp modules 230 can achieve dynamic effects.

[0196] Each lamp module 230 includes at least one lamp bead 2352 and a plurality of square lenses 2354. The square lenses 2354 are configured to transmit light from the lamp bead 2352 to the exterior of the position turn signal lamp 235. The structures of the rear taillight 236, front position lamp 237, and rear position lamp 238 are all consistent with those of the position turn signal lamp 235. Specifically, the structures of the first square lens 2364a, second square lens 2365a, and third square lens 2366a of the rear taillight 236 are consistent with those of the square lens 2354. The structure of the lamp bead 2364b of the rear taillight 236 is consistent with that of the lamp bead 2352.

[0197] It should be noted that the lamp controller 239 of the present application can only realize the three-lamp linkage of the two position turn signals 235 and the front position lights 237, that is, the lamp controller 239 controls the two position turn signals 235 and the front position lights 237 to achieve a dynamic effect. Alternatively, the lamp controller 239 of the present application can only realize the three-lamp linkage of the two rear tail lights 236 and the rear position lights 238, that is, the lamp controller 239 controls the two rear tail lights 236 and the rear position lights 238 to achieve a dynamic effect. This application does not limit the linkage method of the lamps.

[0198] As shown in Figures 42 and 43, the steering assembly 20 includes a steering handle 201, a steering tube 202, and a mounting base 203. The mounting base 203 includes a lower mounting wall 2031, which defines a first channel 2031a extending along the height direction of the vehicle frame 11. The mounting base 203 also includes a left mounting wall 2032 and a right mounting wall 2034, which are opposite to each other along the width direction of the vehicle frame 11. The left mounting wall 2032 and / or the right mounting wall 2034 define a second channel 2032a extending along the width direction of the vehicle frame 11. The first channel 2031a and the second channel 2032a communicate with each other, and both the first channel 2031a and the second channel 2032a are configured to allow wiring harnesses and / or pipes to pass through.

[0199] This arrangement facilitates the routing of wiring harnesses and / or pipes within mounting base 203, thereby eliminating the need for additional components for routing wiring and / or pipes within mounting base 203. This simplifies the structure of mounting base 203 and, in turn, reduces the overall cost of ATV 100. Furthermore, this arrangement improves the compactness of the wiring harnesses and / or pipes within mounting base 203, preventing them from becoming disorganized and potentially interfering with the driver's control of ATV 100, thereby improving the safety of ATV 100. Furthermore, this arrangement prevents disorganized wiring harnesses and / or pipes from becoming exposed and abraded, thereby increasing their service life.

[0200] In one embodiment, the left mounting wall 2032 and / or the right mounting wall 2034 each define a second channel 2032a extending along the width of the vehicle frame 11, with the two second channels 2032a communicating with each other. This arrangement allows wiring harnesses and / or pipes routed within the mounting base 203 to be routed through the two second channels 2032a to both sides of the steering handlebar 201 along the width of the vehicle frame 11, thereby facilitating easier routing of wiring harnesses and / or pipes within the mounting base 203.

[0201] As shown in FIG43 , mounting base 203 is surrounded by an installation space 2033 for accommodating a wiring harness and / or piping, and first channel 2031a and second channel 2032a are at least partially located within accommodating space 2033. With this arrangement, during assembly of the wiring harness and / or piping, installation space 2033 can accommodate overly long wiring harnesses and / or piping, thereby preventing the wiring harnesses and / or piping from being too long to be accommodated and resulting in a disorderly arrangement. This further improves the compactness and neatness of the wiring harnesses and / or piping at mounting base 203.

[0202] In addition, by at least partially recessing the mounting seat 203 to form the mounting space 2033 , the weight of the mounting seat 203 can be reduced, thereby making the steering system 20 more lightweight, and further facilitating the driver to drive the steering system 20 to control the steering of the all-terrain vehicle 100 .

[0203] In this embodiment, the steering assembly 20 further includes a protective plate 204 (see FIG. 42 ), which covers the installation space 2033 and is fixedly connected to the mounting base 203. This arrangement allows the protective plate 204 to limit the position of the wiring harness and / or piping within the installation space 2033, thereby preventing the wiring harness and / or piping from escaping from the installation space 2033 and thereby improving the layout stability of the wiring harness and / or piping within the mounting base 203.

[0204] Secondly, the protective plate 204 can protect the wiring harness and / or pipelines within the installation space 2033. Along the length of the frame 11, the protective plate 204 is located in front of the installation space 2033. Thus, when the all-terrain vehicle 100 is in motion, the protective plate 204 can shield the installation space 2033, preventing flying rocks and gravel from abrading the wiring harness and / or pipelines, thereby facilitating a longer service life of the wiring harness and / or pipelines.

[0205] In one embodiment, the second channel 2032a is configured to reduce the weight of the mounting base 203. Specifically, the ratio of the height H3 of the second channel 2032a along the height direction of the vehicle frame 11 to the height H4 of the mounting base 203 along the height direction of the vehicle frame 11 ranges from 0.4 to 0.62. Specifically, the ratio of the height H3 of the second channel 2032a along the height direction of the vehicle frame 11 to the height H4 of the mounting base 203 along the height direction of the vehicle frame 11 ranges from 0.45 to 0.57. More specifically, the ratio of the height H3 of the second channel 2032a along the height direction of the vehicle frame 11 to the height H4 of the mounting base 203 along the height direction of the vehicle frame 11 is 0.51. By increasing the height H3 of the second channel 2032a along the height direction of the vehicle frame 11, the weight of the mounting base 203 can be further reduced, thereby facilitating the driver's control of the steering system 20. Secondly, this prevents the second channel 2032a from being too large due to its height H3 along the height direction of the vehicle frame 11, thereby preventing the second channel 2032a from being too large and thus reducing the structural strength of the mounting base 203. This helps reduce the overall weight of the mounting base 203 while ensuring the structural strength of the mounting base 203. Furthermore, this prevents the second channel 2032a from being too small due to its height H3 along the height direction of the vehicle frame 11, thereby helping to achieve a lightweight steering system 20.

[0206] As shown in FIG43 , as one embodiment, the mounting base 203 is provided with a weight-reducing hole 2034 extending substantially along the length of the vehicle frame 11. This arrangement further reduces the weight of the mounting base 203 through the weight-reducing hole 2034, thereby further reducing the overall weight of the steering assembly 20 and further reducing the weight of the steering assembly 20.

[0207] Specifically, the weight-reducing hole 2034 is in communication with the installation space 2033. In this manner, the weight-reducing hole 2034 can expand the volume of the installation space 2033, so that the installation space 2033 can accommodate more wiring harnesses and / or pipelines.

[0208] As one embodiment, the second channel 2032a can reduce the weight of the mounting base 203. Specifically, the ratio of the height H3 of the second channel 2032a along the height direction of the vehicle frame 11 to the height H4 of the mounting base 203 along the height direction of the entire vehicle frame 11 ranges from 0.4 to 0.62. Specifically, the ratio of the height H3 of the second channel 2032a along the height direction of the vehicle frame 11 to the height H4 of the mounting base 203 along the height direction of the vehicle frame 11 ranges from 0.45 to 0.57. More specifically, the ratio of the height H3 of the second channel 2032a along the height direction of the vehicle frame 11 to the height H4 of the mounting base 203 along the height direction of the vehicle frame 11 is 0.51. By increasing the height H3 of the second channel 2032a along the height direction of the vehicle frame 11, the weight of the mounting base 203 can be further reduced, thereby facilitating the driver's control of the steering assembly 20. Secondly, this prevents the second channel 2032a from being too large due to its height H3 along the height direction of the vehicle frame 11, thereby preventing the second channel 2032a from being too large and thus reducing the structural strength of the mounting base 203. This helps reduce the overall weight of the mounting base 203 while ensuring the structural strength of the mounting base 203. Furthermore, this prevents the second channel 2032a from being too small due to its height H3 along the height direction of the vehicle frame 11, thereby helping to reduce the weight of the mounting base 203.

[0209] As shown in Figures 44 and 45 , as one embodiment, the steering assembly 20 includes a steering rocker arm 205, a steering ball pin 206, and a steering tie rod 207. The steering rocker arm 205 is connected to the steering tube 202, and the steering tie rod 207 is rotatably connected to the steering rocker arm 205 via the steering ball pin 206. Specifically, the steering rocker arm 205 includes a connecting portion 2051 and a rocker arm portion 2052. The connecting portion 2051 is connected to the steering tube 202, and the rocker arm portion 2052 is rotatably connected to the steering ball pin 206.

[0210] In some embodiments, the connecting portion 2051 and the rocker arm portion 2052 are integrally formed, thereby facilitating improved connection stability between the steering tube 202 and the steering ball pin 206 via the steering rocker arm 205 .

[0211] As shown in FIG46 , a transverse plane 106 perpendicular to the length of the vehicle frame 11 is defined, and the steering ball pin 206 extends substantially along a predetermined straight line 10a. The orthographic projection of the predetermined straight line 10a along the length of the vehicle frame 11 onto the transverse plane 106 is a first projection line, and the orthographic projection of the predetermined straight line 10a onto the longitudinal plane 10s is a second projection line. The orthographic projection of the axis of the steering tube 202 onto the transverse plane 106 is a first axis projection line, and the orthographic projection of the axis of the steering tube 202 onto the longitudinal plane 10s is a second axis projection line.

[0212] One end of the steering rod 207 away from the steering ball pin 206 is connected to the running system 13. When the all-terrain vehicle 100 travels over rough terrain, the running system 13 will jump according to the terrain. At this time, the running system 13 drives the steering ball pin 206 to swing through the steering rod 207.

[0213] In this embodiment, the rocker arm portion 2052 can be bent so that the acute angle β formed between the first projection line and the first axis projection line is in the range of 5° to 45°, and the acute angle Ω formed between the second projection line and the second axis projection line is in the range of 5° to 45°. Specifically, the rocker arm portion 2052 can be bent so that the acute angle β formed between the first projection line and the first axis projection line is in the range of 15° to 30°, and the acute angle Ω formed between the second projection line and the second axis projection line is in the range of 15° to 30°. With this arrangement, the bending of the rocker arm portion 2052 can tilt the steering ball pin 206, thereby providing the steering ball pin 206 with a larger swing stroke. This can prevent the steering ball pin 206 from being too short of a swing stroke due to being arranged along the height direction of the vehicle frame 11, thereby preventing the steering ball pin 206 from colliding and wearing during the swinging process due to the too short swing stroke, thereby facilitating the improvement of the service life of the steering ball pin 206. Secondly, by increasing the swing stroke of the steering ball pin 206, the walking system 13 can have a greater degree of jumping, which in turn helps the all-terrain vehicle 100 to travel over more rugged terrain, thereby improving the passability of the all-terrain vehicle 100.

[0214] The directions in which the steering ball pin 206 swings are defined as a first direction and a second direction, with the first direction and the second direction being opposite. The swing angle of the steering ball pin 206 in the first direction is defined as 30°, and the swing angle of the steering ball pin 206 in the second direction is defined as 30°. If the acute angle β is not within this range, the steering ball pin 206 will deflect in the first or second direction after installation. For example, if the steering ball pin 206 deflects 16° in the first direction after installation and is required to rotate 14° in either the first or second direction, the actual rotation angle of the steering ball pin 206 in the second direction during operation is between 16° and 30°. At this point, the steering ball pin 206 will rotate within its maximum rotation angle, causing wear on the steering ball pin 206 and reducing its service life. Furthermore, if the required rotation angle of the steering ball pin 206 in either the first or second direction exceeds 14°, the installed steering ball pin 206 will not meet this requirement. Therefore, setting the range of the acute angle β within the above-mentioned angle range can increase the service life of the steering ball pin 206 after installation, and enable the steering ball pin 206 after installation to meet greater rotation requirements, thereby increasing the jumping stroke of the walking system 13.

[0215] The range of the acute angle β between the first projection line and the first axis projection line, and the range of the acute angle Ω between the second projection line and the second axis projection line are both angular ranges when the all-terrain vehicle 100 is in a stationary state.

[0216] As shown in Figure 47, the rocker arm portion 2052 extends substantially along the preset plane 10c, and the acute angle Ψ formed between the preset plane 10c and the horizontal plane ranges from 5° to 45°. Specifically, the acute angle Ψ formed between the preset plane 10c and the horizontal plane ranges from 15° to 30°.

[0217] As shown in Figures 45 and 46, as an embodiment, the steering assembly 20 further includes a steering assist mechanism 208, which is connected to the steering tube 202 and can assist the steering tube 202 in steering. Specifically, the steering tube 202 is provided with a first limiting structure 2023, which can cooperate with the vehicle frame 11 to limit the rotation angle of the steering tube 202. The steering rocker arm 205 is provided with a second limiting structure 2024, which can cooperate with the vehicle frame 11 to limit the rotation angle of the steering rocker arm 205. Due to the presence of the steering assist mechanism 208, the steering tube 202 may continue to rotate after the steering rocker arm 205 is limited. Through the above-mentioned arrangement, the steering limit of the first limiting structure 2023 can be used to prevent the steering angle of the steering tube 202 assisted by the steering power mechanism 208 from being greater than the actual maximum limit angle of the steering tube 202, thereby preventing the steering tube 202 from excessively rotating due to excessive rotation of the steering tube 202, thereby preventing the wiring harness, pipelines and components connected to the steering tube 202 from being excessively deflected, which is beneficial to improving the service life of the wiring harness, pipelines and components connected to the steering tube 202.

[0218] The first limiting structure 2023 limits the rotation angle of the steering tube 202 to the actual maximum limiting angle of the steering tube 202. In addition, the limiting angle of the steering tube 202 by the second limiting structure 2024 is consistent with the limiting angle of the steering tube 202 by the first limiting structure 2023.

[0219] In one embodiment, the first limiting structure 2023 is located between the steering assist mechanism 208 and the steering handle 201. The first limiting structure 2023 forms at least a limiting protrusion 2023a to limit the rotation angle of the steering tube 202. In this configuration, the limiting protrusion 2023a can cooperate with the frame 11 to limit the position, thereby limiting the rotation angle of the steering tube 202.

[0220] In one embodiment, the vehicle frame 11 includes a rotating fixture 112 through which the steering tube 202 passes. The steering tube 202 is rotatably connected to the rotating fixture 112. Specifically, the rotating fixture 112 is provided with a cooperating limiter 1121. A second limiter structure 2024 cooperates with the cooperating limiter 1121 to limit the rotation angle of the steering rocker arm 205. In some embodiments, the second limiter structure 2024 may be a rocker arm 2052. The steering tube 202 drives the steering rocker arm 205 to rotate, and the rocker arm 2052 abuts against the limiter to limit the rotation angle of the steering tube 202. This configuration avoids the need for additional structure on the steering tube 202 to limit the rotation angle of the steering tube 202, thereby simplifying the overall structure of the steering tube 202 and reducing the overall cost of the steering tube 202.

[0221] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims appended to this application.

[0222] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of patent protection. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
