[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0032] like Figure 1 and Figure 2 As shown, an all-terrain vehicle 100 includes a frame 11, a travel system 12, a power system 13, a suspension system 14, a brake system 15, a body cover 16, a seat system 17, a transmission system 18 and an electrical system 19. The frame 11 serves as the basic framework of the all-terrain vehicle 100 and is used to support the travel system 12, the power system 13, the suspension system 14, the brake system 15, the body cover 16, the seat system 17, the transmission system 18 and the electrical system 19. The travel system 12 is connected to the frame 11 through the suspension system 14. The power system 13 is transmission-connected to the travel system 12 to provide a driving force for the movement of the travel system 12. The brake system 15 is at least partially located on the travel system 12 to brake the travel system 12. The body cover 16 is generally a plastic part, which is used to cover and connect to the frame 11 to form the appearance of the all-terrain vehicle 100. The body cover 16 and the frame 11 are connected to form a cockpit 20. Specifically, the middle part of the frame 11 and the body cover 16 form the cockpit 20. The seat system 17 is located in the cockpit 20 and is used to carry the driver and passengers. The transmission system 18 is connected to the power system 13 by transmission, and the transmission system 18 is also connected to the travel system 12 by transmission, so that the driving force of the power system 13 is transmitted to the travel system 12 through the transmission system 18. The electrical system 19 is at least partially arranged on the frame 11, and the electrical system 19 is used to control the electrical components on the all-terrain vehicle 100.

[0033] In order to clearly illustrate the technical solution of this application, the following is also defined: Figure 1 In the present application, the length direction of the all-terrain vehicle 100 refers to the front, rear, left, right, top, and bottom. Figure 1 The front-to-back direction in the all-terrain vehicle 100 refers to the width direction of the all-terrain vehicle 100. Figure 1 The left and right directions in the figure, the height direction of the all-terrain vehicle 100 refers to Figure 1 The up and down directions in .

[0034] Specifically, the traveling system 12 is at least partially located at the lower side of the frame 11 , thereby facilitating the movement of the traveling system 12 .

[0035] like Figure 2 , Figure 3 and Figure 4 As shown, as an implementation, the power system 13 includes an engine 131 and an intake and exhaust mechanism 132. The engine 131 is connected to the transmission system 18 so that the driving force of the engine 131 can be transmitted to the travel system 12 through the transmission system 18. The engine 131 is connected to the intake and exhaust mechanism 132, and the intake and exhaust mechanism 132 is used for the intake and exhaust of the engine 131.

[0036] Specifically, the engine 131 includes a connecting rod mechanism, a piston mechanism, a timing mechanism, a cylinder head 1311, a crankshaft 1312, a cylinder block (not shown), a crankcase 1313, and a magneto 1314. The cylinder block is connected to the cylinder head 1311 and the crankcase 1313, respectively. Along the height direction of the all-terrain vehicle 100, the cylinder block is at least partially located between the cylinder head 1311 and the crankcase 1313. The connecting rod mechanism and the crankshaft 1312 are at least partially located in the crankcase 1313, the piston mechanism is located in the cylinder body, the timing mechanism is located in the cylinder head 1311, the crankshaft 1312 and the piston mechanism are connected by the connecting rod mechanism, the crankshaft 1312 and the timing mechanism are connected by the driving, and the crankshaft 1312 and the magneto 1314 are connected by the driving. More specifically, the crankshaft 1312 and the magneto 1314 are fixedly connected so that the crankshaft 1312 and the magneto 1314 can achieve synchronous rotation. Through the above arrangement, the crankshaft 1312 can drive the magneto 1314 to rotate, so that the magneto 1314 generates electrical energy, thereby enabling the magneto 1314 to supply energy to the electrical system 19, etc. Among them, the cylinder head 1311, the cylinder block, and the crankcase 1313 constitute the outer shell of the engine 131, and the connecting rod mechanism, the piston mechanism, the timing mechanism, the crankshaft 1312, and the magneto 1314 are all located in the outer shell of the engine 131.

[0037] In the present application, the engine 131 also includes a pulley 1315 and a generator 1316 (see Fig. 9), the pulley 1315 is located in the outer shell of the engine 131. The pulley 1315 is connected to the crankshaft 1312 in a transmission manner, and the generator 1316 is connected to the pulley 1315 in a transmission manner, so that the driving force of the crankshaft 1312 is transmitted to the generator 1316, so that the generator 1316 can work normally. When the all-terrain vehicle 100 needs high-power electric energy, the power of the magneto 1314 cannot meet the power demand of the all-terrain vehicle 100 at high power. Therefore, the present application cooperates with the generator 1316 and the magneto 1314 to meet the power demand of the all-terrain vehicle 100, thereby preventing the all-terrain vehicle 100 from running out of power.

[0038] In addition, if the volume of the magnetic motor 1314 is enlarged to increase the power generation of the magnetic motor 1314, the volume of the magnetic motor 1314 will be too large, and thus the arrangement requirements of the magnetic motor 1314 with too large volume cannot be met. Therefore, by arranging the magnetic motor 1314 and the generator 1316 at the same time, it is possible to facilitate the arrangement of the magnetic motor 1314 and the generator 1316, reduce the volume of a single motor, thereby facilitating the reduction of the arrangement space of the magnetic motor 1314 and the generator 1316, and thus improve the structural compactness of the engine 131; at the same time, through the above arrangement, the arrangement of the magnetic motor 1314 and the generator 1316 can make full use of the space of the all-terrain vehicle 100, so as to improve the space utilization rate of the all-terrain vehicle 100.

[0039] In the present application, in order to facilitate the connection between the crankshaft 1312, the magnetic motor 1314 and the pulley 1315, the crankshaft 1312 of the present application includes a connecting end 1312a, which is substantially truncated. The magnetic motor 1314 is provided with a connecting hole 1314a, and the connecting end 1312a is at least partially located in the connecting hole 1314a and abuts against the inner wall of the connecting hole 1314a. Optionally, the inner contour of the connecting hole 1314a is substantially consistent with the outer contour of the connecting end 1312a, so as to facilitate the abutment of the connecting end 1312a with the inner wall of the connecting hole 1314a. Specifically, the pulley 1315 is connected to the end surface of the connection end 1312a through a fastener 1315a, and the pulley 1315 is also abutted against the magneto 1314, so that the pulley 1315 has a pressing force on the magneto 1314, so that the magneto 1314 can be fixed to the crankshaft 1312 by the pressing force of the pulley 1315. Through the above arrangement, the magneto 1314 and the crankshaft 1312 can be pressed through the connection end 1312a and the connection hole 1314a, and the pulley 1315, the crankshaft 1312, and the magneto 1314 can be fixed only by a fastener 1315a, thereby simplifying the connection structure among the pulley 1315, the crankshaft 1312, and the magneto 1314, and thus improving the structural compactness of the engine 131.

[0040] Exemplarily, the fastener 1315a can be set as a bolt, and a threaded hole 1312c is opened on the end face of the connecting end 1312a. The fastener 1315a passes through the pulley 1315 and is connected to the threaded hole 1312c, thereby realizing the connection between the pulley 1315, the crankshaft 1312, and the magnetic motor 1314.

[0041] In the present application, an oil hole 1312d extending axially along the crankshaft 1312 is opened in the crankshaft 1312, and the oil hole 1312d is filled with lubricating oil, thereby achieving a lubrication effect on the crankshaft 1312, the magnetic motor 1314 and other surrounding structures, thereby reducing the wear of the crankshaft 1312, the magnetic motor 1314 and other surrounding structures, thereby increasing the service life of the crankshaft 1312 and other surrounding structures.

[0042] The threaded hole 1312c and the oil through hole 1312d are connected to facilitate the processing of the threaded hole 1312c, thereby reducing the processing difficulty of the threaded hole 1312c.

[0043] Specifically, the pulley 1315 is provided with a through hole 1315b extending along the axial direction of the pulley 1315, so that one end of the fastener 1315a can pass through the through hole 1315b and connect with the connecting end 1312a. The end of the fastener 1315a away from the connecting end 1312a abuts against the outer edge of the through hole 1315b, so that the end of the fastener 1315a away from the connecting end 1312a will not be displaced, thereby improving the connection stability of the fastener 1315a.

[0044] More specifically, a counterbore 1315c is provided at one end of the pulley 1315 away from the connection end 1312a, and the counterbore 1315c is communicated with the through hole 1315b, so that the fastener 1315a can pass through the counterbore 1315c and the through hole 1315b. The inner diameter of the counterbore 1315c is larger than the inner diameter of the through hole 1315b, the diameter of the end of the fastener 1315a away from the connection end 1312a is larger than the diameter of the end of the fastener 1315a close to the connection end 1312a, and the diameter of the end of the fastener 1315a away from the connection end 1312a is also larger than the inner diameter of the through hole 1315b and smaller than the inner diameter of the counterbore 1315c, so that the end of the fastener 1315a away from the connection end 1312a is located in the counterbore 1315c.

[0045] In this embodiment, the engine 131 further includes a stopper 1317, which is used to limit the relative rotation of the crankshaft 1312 and the magnetic motor 1314. The connecting end 1312a is provided with a first slot 1312b along the circumference of the connecting end 1312a, and a second slot (not shown) is provided on the inner wall of the connecting hole 1314a. The stopper 1317 is at least partially located in the first slot 1312b and at least partially located in the second slot, so that the phase between the crankshaft 1312 and the magnetic motor 1314 is fixed, and the magnetic motor 1314 can work normally.

[0046] As an implementation method, the outer shell of the engine 131 also includes an end cover 1318. After the crankcase 1313 and the end cover 1318 are connected, an inner space 1301 is formed. The magnetic motor 1314 and the crankshaft 1312 are at least partially located in the inner space 1301. The pulley 1315 at least partially passes through the end cover 1318 and is located outside the inner space 1301, thereby preventing interference from other components between the pulley 1315 and the generator 1316, thereby facilitating the transmission connection between the pulley 1315 and the generator 1316.

[0047] Specifically, the end cover 1318 is provided with a mounting groove 1318a, in which a mounting bearing 1318b is provided, and the pulley 1315 is also rotatably connected to the end cover 1318 via the mounting bearing 1318b.

[0048] In the present application, the length of the portion of the pulley 1315 located outside the space 1301 in the box and in the mounting groove 1318a along the axial direction of the pulley 1315 is defined as the outer extension length Q1. Since the outer edge length Q1 is relatively long, the present application provides a mounting bearing 1318b to prevent the pulley 1315 from shaking or deflecting during operation, thereby improving the working stability of the pulley 1315.

[0049] In this embodiment, the total length of the pulley 1315 along the axial direction of the pulley 1315 is defined as the pulley length Q2, and the ratio of the outer extension Q1 to the pulley length Q2 is greater than or equal to 0.56 and less than or equal to 0.84. Further, the ratio of the outer extension Q1 to the pulley length Q2 is greater than or equal to 0.63 and less than or equal to 0.77. Exemplarily, the ratio of the outer extension Q1 to the pulley length Q2 can also be 0.7. Through the above-mentioned settings, it is possible to avoid the outer extension Q1 being too long, which may cause the pulley 1315 to shake or deflect during operation, so as to improve the working stability of the pulley 1315; it is also possible to avoid the outer extension Q1 being too short, which may cause the pulley 1315 to interfere with surrounding components such as the end cover 1318, thereby improving the working stability of the pulley 1315.

[0050] Optionally, the end cover 1318 is further provided with a through hole 1318c for the pulley 1315 to pass through, the through hole 1318c is connected to the mounting groove 1318a, and an oil seal 1315d is sleeved on the pulley 1315, and the oil seal 1315d is interference fit with the through hole 1318c. The oil seal 1315d is used to seal the end cover 1318, thereby improving the sealing of the box space 1301, so as to facilitate the normal operation of the engine 131.

[0051] like Figure 5 As shown, as an implementation, the intake and exhaust mechanism 132 includes an intake pipe 1321 and an exhaust pipe 1322, both of which are connected to the engine 131, the intake pipe 1321 is used for the intake of the engine 131, and the exhaust pipe 1322 is used for the exhaust of the engine 131, so as to achieve the normal operation of the engine 131. Specifically, an intake passage 1311a and an exhaust passage 1311b are provided in the cylinder head 1311, the intake pipe 1321 is communicated with the intake passage 1311a, and the exhaust pipe 1322 is communicated with the exhaust passage 1311b.

[0052] In this embodiment, the intake and exhaust mechanism 132 further includes an intake branch pipe 1323, which is in communication with the outside and the intake pipe 1321, and is arranged close to the exhaust pipe 1322. Since the surface temperature of the exhaust pipe 1322 is high, the above arrangement can transfer the heat of the exhaust pipe 1322 to the intake branch pipe 1323, so that the air sucked in by the intake branch pipe 1323 can be heated by the exhaust pipe 1322, thereby making the temperature of the air sucked in by the intake branch pipe 1323 higher, so that the air with higher temperature sucked in by the intake branch pipe 1323 is mixed with the air sucked in by the intake pipe 1321 and then enters the engine 131, thereby increasing the intake temperature of the engine 131 when it is running in a low temperature environment, which is beneficial to improving the combustion efficiency of the engine 131, so as to increase the fuel utilization rate of the engine 131.

[0053] It should be noted that the intake branch pipe 1323 can be connected to any position on the intake pipe 1321 , so that the air in the intake branch pipe 1323 can be mixed with the air in the intake pipe 1321 in the intake pipe 1321 .

[0054] Exemplarily, the intake and exhaust mechanism 132 further includes an intake valve 1324 for controlling the intake amount in the intake branch pipe 1323. The intake valve 1324 is at least partially installed in the intake branch pipe 1323, so that the intake amount in the intake valve 1324 can be controlled to control whether the intake branch pipe 1323 is inhaled, and the flow rate of the high-temperature air inhaled by the intake branch pipe 1323 flowing into the intake passage 1311a can be controlled, thereby controlling the intake temperature of the engine 131. That is, through the above arrangement, the flow rate of the high-temperature air inhaled by the intake branch pipe 1323 can be controlled, thereby controlling the temperature of the air entering the intake passage 1311a to meet different working requirements of the engine 131.

[0055] Specifically, the intake valve 1324 is installed at the connecting point between the intake branch pipe 1323 and the intake pipe 1321, so that when the intake valve 1324 is opened, the rate at which air with higher temperature flows into the intake pipe 1321 can be increased, which is beneficial to improving the mixing efficiency of the air inhaled by the intake branch pipe 1323 and the air inhaled by the intake pipe 1321.

[0056] As an implementation method, the intake and exhaust mechanism 132 further includes a temperature sensing mechanism 1325, which is disposed in the intake pipe 1321 and is electrically connected to the intake valve 1324. The temperature sensing mechanism 1325 is used to detect the intake temperature of the intake rod 1321. When the intake temperature is lower than a preset temperature value, the temperature sensing mechanism 1325 can control the opening and closing degree of the intake valve 1324 to control the flow rate of air in the intake branch 1323 entering the intake pipe 1321, thereby adjusting the intake temperature of the engine 131. It should be noted that the preset temperature value can be adjusted according to actual conditions.

[0057] Specifically, the connection point between the intake pipe 1321 and the intake branch pipe 1323 is defined as the pipeline connection point, and the temperature sensing mechanism 1325 is located between the pipeline connection point and the intake duct 1311a. Since the air passing through the intake pipe 1321 and the intake branch pipe 1323 is mixed and then enters the engine 131 through the intake duct 1311a, the temperature sensing mechanism 1325 is arranged between the pipeline connection point and the intake duct 1311a, which can improve the detection accuracy of the temperature sensing mechanism 1325 for the intake temperature entering the engine 131, thereby more accurately controlling the intake temperature of the engine 131.

[0058] Preferably, the temperature sensing mechanism 1325 is arranged close to the intake duct 1311a. The closer the temperature sensing mechanism 1325 is arranged to the intake duct 1311a, the more accurately it can detect the temperature of the air entering the engine 131. When the temperature sensing mechanism 1325 detects that the intake temperature is lower than a preset temperature value, the opening and closing degree of the intake valve 1324 can be increased to increase the air flow of the intake branch 1323, thereby increasing the intake temperature; when the temperature sensing mechanism 1325 detects that the intake temperature is too high, the opening and closing degree of the intake valve 1324 can be reduced to reduce the air flow of the intake branch 1323 entering the intake duct 1321, thereby making the intake temperature meet the intake demand of the engine 131.

[0059] Furthermore, the intake branch pipe 1323 is made of metal material, such as aluminum alloy, titanium alloy, etc. In the present application, since the temperature of the exhaust pipe 1322 is relatively high, the intake branch pipe 1323 can at least partially contact the exhaust pipe 1322, thereby improving the heating efficiency of the air, so as to increase the intake temperature of the engine 131 in a low temperature environment, thereby reducing the fuel consumption of the all-terrain vehicle 100 in a low temperature environment.

[0060] Exemplarily, the intake branch pipe 1323 is at least partially arranged around the exhaust pipe 1322, so that the area of ​​the intake branch pipe 1323 close to the exhaust pipe 1322 is increased, further improving the heating efficiency of the air in the intake branch pipe 1323.

[0061] For example, since the temperature at the connection point between the exhaust duct 1311b and the exhaust pipe 1322 is higher than the temperature at other positions of the exhaust pipe 1322, the intake branch pipe 1323 is arranged close to the connection point between the exhaust duct 1311b and the exhaust pipe 1322 in the present application to further improve the heating efficiency of the air in the intake branch pipe 1323.

[0062] As an optional implementation, a first air intake channel 1321a is formed in the air intake pipe 1321, and a second air intake channel 1323a is formed in the air intake branch pipe 1323. The air temperature in the second air intake channel 1323a is greater than the temperature in the first air intake channel 1321a. Since the air intake branch pipe 1323 is arranged near the exhaust pipe 1322, the exhaust pipe 1322 can heat the air in the air intake branch pipe 1323, so that the air temperature in the air intake branch pipe 1323 is greater than the ambient air temperature. The air in the second air intake channel 1323a is ambient air, so the air temperature in the second air intake channel 1323a is substantially consistent with the ambient air temperature.

[0063] like Figure 2 and Figure 6As shown, as an implementation method, a rear accommodating space 113 is formed around the rear of the frame 11, the power system 13 is at least partially located in the rear accommodating space 113, and the transmission system 18 is also at least partially located in the rear accommodating space 113 to improve the space utilization of the rear of the frame 11.

[0064] Among them, the intake and exhaust mechanism 132 also includes an air filter mechanism 1326 and an air duct 1327. The engine 131 is connected to the air filter mechanism 1326, and the air duct 1327 is connected to the air filter mechanism 1326, so that the air in the environment can enter the air filter mechanism 1326 through the air duct 1327, and be transported to the engine 131 after being filtered by the air filter mechanism 1326.

[0065] The transmission system 18 includes a gearbox 181, a transmission mechanism (not shown) and a continuously variable transmission mechanism 183. Specifically, the transmission mechanism is located in the gearbox 181, the transmission mechanism is connected to the travel system 12, the continuously variable transmission mechanism 183 is connected to the transmission mechanism, and the continuously variable transmission mechanism 183 is connected to the engine 131, so that the driving force of the engine 131 can be transmitted to the travel system 12 through the continuously variable transmission mechanism 183 and the transmission mechanism. Among them, the continuously variable transmission mechanism 183 can be a CVT (Continuously Variable Transmission).

[0066] The seat system 17 is at least partially located at the front side of the rear accommodation space 113 , and the seat system 17 includes a backrest 177 for providing support for the back of a driver and / or a passenger.

[0067] Specifically, along the height direction of the ATV 100 , the air filter mechanism 1326 and the seat system 17 at least partially overlap, thereby improving the structural compactness and space utilization of the air filter mechanism 1326 and the seat system 17 along the height direction of the ATV 100 .

[0068] Along the length direction of the ATV 100, the engine 131 and the gearbox 181 at least partially overlap, and the engine 131 and the gearbox 181 are both located at the rear side of the seat system 17, so that the seat system 17, the engine 131 and the gearbox 181 have a high structural compactness along the length direction of the ATV 100. In addition, along the length direction of the ATV 100, the air duct 1327 and the backrest 177 at least partially overlap, so that the position of the air duct 1327 can be increased, which is conducive to increasing the wading depth of the ATV 100, and further, it can prevent external water and other liquids from entering the air filter mechanism 1326 and the engine 131 through the air duct 1327, which is conducive to increasing the service life of the air filter mechanism 1326 and the engine 131.

[0069] Along the width direction of the all-terrain vehicle 100, the engine 131 and the continuously variable transmission mechanism 183 at least partially overlap, and along the width direction of the all-terrain vehicle 100, the gearbox 181 and the continuously variable transmission mechanism 183 at least partially overlap, thereby improving the structural compactness of the engine 131, the gearbox 181 and the continuously variable transmission mechanism 183 along the width direction of the all-terrain vehicle 100.

[0070] In the present application, along the length direction of the all-terrain vehicle 100 , the engine 131 is located between the gearbox 181 and the seat system 17 , so that the gearbox 181 is closer to the traveling system 12 , thereby facilitating the transmission between the speed change mechanism and the traveling system 12 .

[0071] Exemplarily, the air filter mechanism 1326 is located at the lower side of the seat system 17 to improve the space utilization rate at the lower side of the seat system 17; at the same time, the seat system 17 can be disassembled to facilitate the inspection and maintenance of the air filter mechanism 1326.

[0072] As an implementation method, the all-terrain vehicle 100 also includes a cargo box system 21, which is at least partially arranged on the frame 11 and located at the rear of the frame 11. Specifically, the cargo box system 21 is located on the upper side of the rear accommodating space 113. The cargo box system 21 is used to carry cargo to improve the cargo carrying capacity of the all-terrain vehicle 100.

[0073] Along the length direction of the all-terrain vehicle 100, the air duct 1327 is at least partially located between the cargo box system 21 and the backrest 177, so as to improve the space utilization between the cargo box system 21 and the backrest 177; at the same time, there are fewer or basically no parts between the cargo box system 21 and the backrest 177, thereby preventing the air duct 1327 from interfering with other parts, which is beneficial to the installation and normal operation of the air duct 1327.

[0074] In this embodiment, along the width direction of the all-terrain vehicle 100, the air duct 1327 and the air filter mechanism 1326 are located on the same side of the engine 131, which helps to reduce the length of the air duct 1327 and improve the efficiency of air entering the air filter mechanism 1326.

[0075] like Figure 7 and Figure 8As shown, as an implementation, the vehicle body cover 16 includes a side air intake mechanism 162, and the air intake and exhaust mechanism 132 includes an air intake pipe 1328, and the air intake pipe 1328 is respectively connected to the continuously variable transmission mechanism 183 and the side air intake mechanism 162, and the side air intake mechanism 162 is exposed to the ATV 100 and is connected to the outside. Through the above arrangement, the outside air can enter the air intake pipe 1328 through the side air intake mechanism 162, and enter the continuously variable transmission mechanism 183 through the air intake pipe 1328, so as to realize the air intake of the continuously variable transmission mechanism 183. In addition, through the above arrangement, the air intake position of the continuously variable transmission mechanism 183 can also be located on the outer surface of the ATV 100, thereby preventing the side air intake mechanism 162 from inhaling the air with a high temperature and more impurities inside the ATV 100, which is beneficial to the cooling of the continuously variable transmission mechanism 183, and preventing excessive impurities from affecting the service life of the continuously variable transmission mechanism 183.

[0076] Exemplarily, the air intake and exhaust mechanism 132 further includes an air outlet pipe 1329, which is connected to the continuously variable transmission mechanism 183 and is used to discharge the air in the continuously variable transmission mechanism 183. The air outlet of the air outlet pipe 1329 is arranged toward the engine 131 and the exhaust pipe 1322. Since the air temperature in the continuously variable transmission mechanism 183 is lower than the temperature of the engine 131 and the exhaust pipe 1322 in normal operation, the above arrangement allows the air in the continuously variable transmission to be transported to the engine 131 and the exhaust pipe 1322 through the air outlet pipe 1329, thereby facilitating the cooling of the engine 131 and the exhaust pipe 1322; at the same time, the air cooled by the continuously variable transmission mechanism 183 can be fully utilized to improve the resource utilization rate of the all-terrain vehicle 100.

[0077] like Figure 6 As shown, as an implementation, the intake and exhaust mechanism 132 also includes a muffler 132a, and the exhaust pipe 1322 is respectively connected to the muffler 132a and the engine 131, so that the exhaust gas in the engine 131 is transported to the muffler 132a after passing through the exhaust pipe 1322.

[0078] In the height direction of the ATV 100, the exhaust pipe 1322 and the gearbox 181 at least partially overlap, thereby improving the structural compactness of the exhaust pipe 1322 and the gearbox 181 along the height direction of the ATV 100. Specifically, the exhaust pipe 1322 is located on the upper side of the gearbox 181, thereby improving the space utilization rate of the upper side of the gearbox 181, and further improving the structural compactness of the exhaust pipe 1322 and the gearbox 181 along the height direction of the ATV 100.

[0079] In the present application, the crankshaft 1312 and the continuously variable transmission mechanism 183 are transmission connected. Along the width direction of the all-terrain vehicle 100, the magnetic motor 1314 and the continuously variable transmission mechanism 183 are respectively located on both sides of the crankshaft 1312, so that the magnetic motor 1314 and the continuously variable transmission mechanism 183 are respectively transmission connected to the crankshaft 1312, preventing the magnetic motor 1314 and the continuously variable transmission mechanism 183 from interfering with each other, thereby improving the working stability of the magnetic motor 1314 and the continuously variable transmission mechanism 183.

[0080] like Fig. 9 and Fig.10 As shown, illustratively, the generator 1316 and the magnetic motor 1314 are located on the same side of the crankshaft 1312, so that the crankshaft 1312 and the generator 1316 are connected by a pulley 1315. Specifically, the generator 1316 is located on the upper side of the magnetic motor 1314 and the crankshaft 1312, and the generator 1316 is also located on the rear side of the magnetic motor 1314 and the crankshaft 1312, so as to facilitate the arrangement of the generator 1316; at the same time, the space utilization rate of the magnetic motor 1314 and the upper side and the rear side of the crankcase 1313 can be improved.

[0081] Exemplarily, the all-terrain vehicle 100 further includes an air conditioning system 22, which includes a compressor 2223. The compressor 2223 is connected to the crankshaft 1312 in a transmission manner, and the compressor 2223 is connected to the generator 1316 in a transmission manner, so that the crankshaft 1312 can drive the generator 1316 and the compressor 2223 to work at the same time, thereby simplifying the transmission structure between the crankshaft 1312 and the generator 1316, and between the crankshaft 1312 and the compressor 2223, thereby improving the compactness of the structure of the compressor 2223, the crankshaft 1312, and the generator 1316. Specifically, the compressor 2223, the generator 1316, and the magnetic motor 1314 are located on the same side of the crankshaft 1312, so as to facilitate the transmission between the crankshaft 1312 and the generator 1316, and between the crankshaft 1312 and the magnetic motor 1314. In the present application, the compressor 2223 is located at the rear side of the magnetic motor 1314, that is, the compressor 2223 is located at the rear side of the crankshaft 1312 to improve the space utilization of the rear side of the magnetic motor 1314; the compressor 2223 is also located at the lower side of the generator 1316 to improve the space utilization of the lower side of the generator 1316.

[0082] It should be noted that, in the present application, the axis of the magnetic motor 1314 and the rotation center line of the crankshaft 1312 are substantially coincident.

[0083] As an implementation method, the axis of the magnetic motor 1314, the axis of the generator 1316, and the axis of the compressor 2223 all extend substantially along the width direction of the all-terrain vehicle 100, defining a longitudinal plane 101 perpendicular to the width direction of the all-terrain vehicle 100, the projection of the axis of the magnetic motor 1314 on the longitudinal plane 101 along the width direction is the magnetic motor projection point, the projection of the axis of the generator 1316 on the longitudinal plane 101 along the width direction is the generator projection point, the projection of the axis of the compressor 2223 on the longitudinal plane 101 along the width direction is the compressor projection point, the line connecting the magnetic motor projection point and the generator projection point is the first line, the line connecting the generator projection point and the compressor projection point is the second line, and the angle α between the first line and the second line is greater than or equal to 43° and less than or equal to 65°. Specifically, the angle α between the first line and the second line is greater than or equal to 48° and less than or equal to 60°. More specifically, the angle α between the first line and the second line can also be 54°. Through the above arrangement, it is possible to avoid the angle α between the first connecting line and the second connecting line being too large, which may cause the distance between the magnetic motor 1314, the generator 1316, and the compressor 2223 to increase along the length direction of the all-terrain vehicle 100, thereby facilitating the improvement of the structural compactness of the magnetic motor 1314, the generator 1316, and the compressor 2223. In addition, through the above arrangement, it is possible to avoid the angle α between the first connecting line and the second connecting line being too small, which may cause interference between the magnetic motor 1314, the generator 1316, and the compressor 2223, or it is possible to avoid the angle α between the first connecting line and the second connecting line being too small, which may cause interference between the magnetic motor 1314, the generator 1316, and the compressor 2223 and other components, thereby improving the working stability of the magnetic motor 1314, the generator 1316, and the compressor 2223.

[0084] Exemplarily, the line connecting the compressor projection point and the magneto projection point is the third line, and the angle β between the third line and the first line is greater than or equal to 34° and less than or equal to 52°. Specifically, the angle β between the third line and the first line is greater than or equal to 38° and less than or equal to 48°. More specifically, the angle β between the third line and the first line can also be 43°. Through the above arrangement, it is possible to avoid the angle β between the third line and the first line being too large, thereby preventing the distance between the magneto 1314, the generator 1316, and the compressor 2223 in the height direction of the all-terrain vehicle 100 from increasing, thereby facilitating the improvement of the structural compactness of the magneto 1314, the generator 1316, and the compressor 2223. In addition, through the above-mentioned settings, it is possible to avoid the angle β between the third connecting line and the first connecting line being too small, thereby causing interference between the magnetic motor 1314, the generator 1316, and the compressor 2223, or it is possible to avoid the angle β between the third connecting line and the first connecting line being too small, thereby causing interference between the magnetic motor 1314, the generator 1316, the compressor 2223 and other components, so as to improve the working stability of the magnetic motor 1314, the generator 1316, and the compressor 2223.

[0085] As an implementation method, the distance between the projection point of the magnetic motor and the projection point of the generator in the height direction of the all-terrain vehicle 100 is the motor height H1, the distance between the projection point of the magnetic motor and the projection point of the generator in the length direction of the all-terrain vehicle 100 is the motor length H2, and the ratio of the motor height H1 to the motor length H2 is greater than or equal to 0.88 and less than or equal to 1.4. Specifically, the ratio of the motor height H1 to the motor length H2 is greater than or equal to 0.9 and less than or equal to 1.2. More specifically, the ratio of the motor height H1 to the motor length H2 can also be 1.1. Through the above-mentioned settings, it is possible to avoid the ratio of the motor height H1 to the motor length H2 being too large, which leads to an excessive distance between the magnetic motor 1314 and the generator 1316 along the height direction of the all-terrain vehicle 100, thereby improving the structural compactness of the magnetic motor 1314 and the generator 1316 along the height direction of the all-terrain vehicle 100. In addition, through the above configuration, it is possible to avoid the ratio of the motor height H1 to the motor length H2 being too small, which would cause the distance between the magnetic motor 1314 and the generator 1316 along the length direction of the all-terrain vehicle 100 to be too large, thereby improving the structural compactness of the magnetic motor 1314 and the generator 1316 along the length direction of the all-terrain vehicle 100.

[0086] As an implementation method, the pulley 1315 is fixedly connected to the crankshaft 1312, and the pulley 1315, the generator 1316 and the compressor 2223 are connected through a belt drive, so that the crankshaft 1312 can simultaneously drive the generator 1316 and the compressor 2223 to move through the pulley 1315, so as to simplify the transmission structure between the crankshaft 1312 and the generator 1316, and the crankshaft 1312 and the compressor 2223, thereby improving the compactness of the structure of the generator 1316, the crankshaft 1312 and the compressor 2223. Specifically, the belt passes through the pulley 1315, the generator 1316 and the compressor 2223 in sequence, so that the pulley 1315, the generator 1316 and the compressor 2223 are driven by the same belt.

[0087] In the present application, the engine 131 further includes a guide wheel train 1319, which is connected to the crankcase 1313 and is used to change the direction of the belt, thereby facilitating the transmission between the pulley 1315, the generator 1316 and the compressor 2223. Specifically, the pulley 1315, the guide wheel train 1319, the generator 1316 and the compressor 2223 are connected by belt transmission, so that the crankshaft 1312 can simultaneously drive the guide wheel train 1319, the generator 1316 and the compressor 2223 through the pulley 1315, so as to simplify the transmission structure between the crankshaft 1312 and the generator 1316, between the crankshaft 1312 and the compressor 2223, and between the crankshaft 1312 and the guide wheel train 1319, thereby improving the structural compactness of the generator 1316, the guide wheel train 1319, the crankshaft 1312 and the compressor 2223. Specifically, the belt passes through the pulley 1315, the guide wheel system 1319, the generator 1316 and the compressor 2223 in sequence, so that the guide wheel system 1319, the pulley 1315, the generator 1316 and the compressor 2223 are driven by the same belt.

[0088] In this embodiment, the belt between the guide wheel train 1319 and the generator 1316 is defined as the first belt portion, and the belt between the generator 1316 and the compressor 2223 is defined as the second belt portion. The angle γ between the extension direction of the first belt portion and the extension direction of the second belt portion is greater than or equal to 34° and less than or equal to 52°. Specifically, the angle γ between the extension direction of the first belt portion and the extension direction of the second belt portion is greater than or equal to 38° and less than or equal to 48°. More specifically, the angle γ between the extension direction of the first belt portion and the extension direction of the second belt portion can also be 43°. Through the above arrangement, it is possible to avoid the angle γ between the extension direction of the first belt portion and the extension direction of the second belt portion being too large, resulting in too small a contact area between the belt and the generator 1316, and the belt and the compressor 2223, thereby avoiding the contact area between the belt and the generator 1316, and the belt and the compressor 2223 being too small, resulting in reduced reliability between the belt and the generator 1316, and the belt and the compressor 2223, thereby improving the working stability between the belt and the generator 1316, and the belt and the compressor 2223. In addition, through the above arrangement, it is possible to avoid the angle γ between the extension direction of the first belt portion and the extension direction of the second belt portion being too small to cause interference between the generator 1316, the guide gear train 1319 and the compressor 2223.

[0089] Exemplarily, the belt between the guide wheel system 1319 and the pulley 1315 is defined as the third belt portion, the belt between the compressor 2223 and the pulley 1315 is defined as the fourth belt portion, and the angle Ω between the extension direction of the third belt portion and the extension direction of the fourth belt portion is greater than or equal to 120° and less than or equal to 182°. Specifically, the angle Ω between the extension direction of the third belt portion and the extension direction of the fourth belt portion is greater than or equal to 135° and less than or equal to 167°. More specifically, the angle Ω between the extension direction of the third belt portion and the extension direction of the fourth belt portion can also be 151°. Through the above arrangement, it is possible to avoid the angle Ω between the extension direction of the third belt portion and the extension direction of the fourth belt portion being too large, which may result in a too small contact area between the belt and the pulley 1315, and between the belt and the compressor 2223, thereby avoiding the contact area between the belt and the pulley 1315, and between the belt and the compressor 2223 being too small, which may result in a reduction in reliability between the belt and the pulley 1315, and between the belt and the compressor 2223, thereby improving the working stability between the belt and the pulley 1315, and between the belt and the compressor 2223. In addition, through the above arrangement, it is possible to avoid the angle Ω between the extension direction of the third belt portion and the extension direction of the fourth belt portion being too small, which may result in interference between the pulley 1315, the guide wheel train 1319, and the compressor 2223.

[0090] like Fig.10 and Fig.11 As shown, as an implementation method, the power system 13 also includes an installation tool 134 for installing a belt, the pulley 1315 is connected to the crankshaft 1312 through a fastener 1315a, the radial length of the installation tool 134 along the pulley 1315 is greater than the outer diameter of the pulley 1315, one end of the installation tool 134 is connected to the fastener 1315a, and the end of the installation tool 134 away from the fastener 1315a is provided with a groove 1341 for placing the belt.

[0091] When the installation tool 134 is connected to the fastener 1315a, the belt is located in the slot 1341 and the belt is installed on the generator 1316, the installation tool 134 rotates along the axis of the pulley 1315 and drives the pulley 1315 to rotate, so that the belt is installed on the pulley 1315. Through the above arrangement, the installation efficiency of the belt can be improved, and the difficulty of the belt installation can be reduced, thereby improving the assembly efficiency of the belt.

[0092] Specifically, the installation tooling 134 includes a tooling connection portion 1342 and a belt guide portion 1343, the tooling connection portion 1342 is connected to the fastener 1315a, the belt guide portion 1343 basically extends along the radial direction of the pulley 1315, one end of the belt guide portion 1343 is connected to or integrally formed with the tooling connection portion 1342, and the end of the belt guide portion 1343 away from the tooling connection portion 1342 is provided with a groove 1341 for installing the tooling 134.

[0093] More specifically, the tooling connection portion 1342 is provided with a snap-in hole 1342a which is substantially consistent with the outer contour of the fastener 1315a, and the fastener 1315a is at least partially located in the snap-in hole 1342a and snap-in with the snap-in hole 1342a, thereby facilitating the assembly and disassembly of the tooling connection portion 1342 and the fastener 1315a.

[0094] like Fig.12 , Fig.13 and Fig.14 As shown, as an implementation method, the power system 13 also includes a box bracket 133. Since the all-terrain vehicle 100 is small in size and has limited layout space, it is difficult to arrange the positions of the engine 131, the gearbox 181, the compressor 2223 and the generator 1316. In order to improve the structural compactness of the engine 131 and reduce the number of parts developed, the gearbox 181 provided in the present application can be connected to the crankcase 1313 through the box bracket 133. The box bracket 133 is also provided with a first connecting portion 1331 and / or a second connecting portion 1332. The first connecting portion 1331 can be installed with the compressor 2223 so that the compressor 2223 is connected to the first connecting portion 1331. The second connecting portion 1332 can be installed with the generator 1316 so that the generator 1316 is connected to the second connecting portion 1332, so as to improve the compactness of the connection structure of the crankcase 1313, the generator 1316, the gearbox 181 and the compressor 2223. At the same time, through the above-mentioned arrangement, the connection structure between the compressor 2223 and the generator 1316 can be integrated on the box bracket 133, simplifying the connection structure between the compressor 2223 and the generator 1316, thereby reducing the layout space requirement for the generator 1316 and the compressor 2223, so as to improve the structural compactness of the engine 131.

[0095] Specifically, the surface of the box bracket 133 is at least partially raised to form a first connecting portion 1331, and a first connecting hole 1331a is opened on the first connecting portion 1331. The compressor 2223 is connected to the first connecting hole 1331a by bolts to strengthen the connection strength between the compressor 2223 and the first connecting portion 1331, so that the compressor 2223 can be stably connected through the box bracket 133, thereby improving the structural compactness of the engine 131 and the compressor 2223.

[0096] Specifically, the second connecting part 1332 is basically a cylinder, and the second connecting part 1332 is provided with a second connecting hole 1334a along its axial direction. The generator 1316 is connected to the second connecting hole 1334a by bolts to strengthen the connection strength between the generator 1316 and the second connecting part 1332, so that the generator 1316 can be stably connected through the box bracket 133, thereby improving the structural compactness of the engine 131.

[0097] Illustratively, the axis of the second connection portion 1332 is substantially perpendicular to the axis of the first connection hole 1331 a . When the first connection part 1331 and the second connection part 1332 are simultaneously provided on the case bracket 133, the compressor 2223 is connected to the first connection part 1331 along the axis of the first connection hole 1331a, and the generator 1316 can be connected to the second connection part 1332 along the axis of the second connection part 1332, and the axis of the second connection part 1332 is basically perpendicular to the axis of the first connection hole 1331a, so that the connection directions of the first connection part 1331 and the second connection part 1332 are different, so that the connections of the compressor 2223 and the generator 1316 do not interfere with each other, and can balance the force of the case bracket 133, so that the crankcase 1313, the gearbox 181, the generator 1316 and the compressor 2223 can be stably connected at the same time through the case bracket 133, thereby further improving the connection stability and structural compactness of the crankcase 1313, the gearbox 181, the generator 1316 and the compressor 2223.

[0098] Exemplarily, two first connection parts 1331 and two second connection parts 1332 are provided, and the two first connection parts 1331 are located between the two second connection parts 1332. When the first connection parts 1331 and the second connection parts 1332 are provided on the box support 133 at the same time, the two first connection parts 1331 can enhance the stability of connecting the compressor 2223, and the two second connection parts 1332 can enhance the stability of connecting the motor 1319. In addition, the two first connection parts 1331 are located between the two second connection parts 1332, so that when the two first connection parts 1331 are stably connected to the compressor 2223, the two second connection parts 1332 are not affected in stably connecting the generator 1316, thereby further improving the connection stability and structural compactness of the crankcase 1313, the gearbox 181, the generator 1316 and the compressor 2223.

[0099] As an implementation, the box support 133 includes a first mounting structure 1333 and a second mounting structure 1334, the first mounting structure 1333 and the second mounting structure 1334 are integrally formed, the first mounting structure 1334 is connected to the gearbox 181, the second mounting structure 1334 is connected to the crankcase 1313, and the first connecting portion 1331 and the second connecting portion 1332 are both arranged on the second mounting structure 1334. The arrangement of this embodiment can make the crankcase 1313 connected to the second mounting structure 1334, the generator 1316 connected to the second mounting structure 1334 through the second connecting portion 1332, and the compressor 2223 connected to the second mounting structure 1334 through the first connecting portion 1331, under the premise that the connection between the first mounting structure 133 and the gearbox 181 is not affected, so that the second mounting structure 1334 can be stably connected to the crankcase 1313, the generator 1316 and the compressor 2223. At the same time, the first mounting structure 1333 and the second mounting structure 1334 are integrally formed, which further improves the connection stability and structural compactness of the crankcase 1313, the gearbox 181, the generator 1316 and the compressor 2223.

[0100] Specifically, the first mounting structure 1333 at least partially extends toward the gearbox 181 to form a plurality of columnar portions 1333a, and the columnar portions 1333a are provided with first mounting holes 1333b, and the gearbox 181 is connected to the first mounting holes 1333b by bolts, so as to strengthen the stability of the gearbox 181 connected to the first mounting structure 1333, so that the box support 133 can be stably connected to the gearbox 181. The extension length of the first mounting structure 1333 can be set according to the specific connection requirements of the gearbox 181, so as to ensure that the first mounting mechanism 1333 is connected to the gearbox 181, while not affecting the second mounting mechanism 1334 connecting to the crankcase 1313, the generator 1316 and / or the compressor 2223.

[0101] Specifically, the second mounting structure 1334 is provided with a plurality of second mounting holes 1334a, and second mounting holes 1334a are provided on both sides of the second mounting structure 1334. The crankcase 1313 is connected to the second mounting holes 1334a by bolts to strengthen the stability of the crankcase 1313 connected to the second mounting structure 1334, so that the case bracket 133 can be stably connected to the crankcase 1313 without affecting the connection of the second mounting structure 1334 to the generator 1316 and / or the compressor 2223.

[0102] In this embodiment, along the height direction of the all-terrain vehicle 100, both sides of the second mounting structure 1334 at least partially extend to form an extension portion 1334b, and the first connection portion 1331 and the second connection portion 1332 are both located on the extension portion 1334b. The length of the extension portion 1334b can be set according to specific connection requirements. Since the second mounting structure 1334 is connected to the crankcase 1313, the generator 1316 and the compressor 2223, the extension portion 1334b allows the first connection portion 1331 to be connected to the crankcase 1313 while having enough space to connect the generator 1316 and / or the compressor 2223, so that the compactness of the connection structure of the crankcase 1313, the generator 1316 and the compressor 2223 can be improved without affecting the normal connection and operation of each component.

[0103] The box support 133 further includes a reinforcing rib 1335, which is located on the first mounting structure 1333 and the second mounting structure 1334. The reinforcing rib 1335 can enhance the strength and rigidity of the first mounting structure 1333 connected to the crankcase 1313, and enhance the strength and rigidity of the second mounting structure 1334 connected to the crankcase 1313, the generator 1316 and the compressor 2223 without increasing the thickness of the box support 133, so as to save material usage and reduce costs; at the same time, the stability and structural compactness of the crankcase 1313, the generator 1316, the gearbox 181 and the compressor 2223 connected through the box support 133 can be further improved.

[0104] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
