[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0033] See Figure 1 and Figure 2 An all-terrain vehicle 100 includes a frame assembly 11, a power system 12, body panels 13, a heating system 14, a cooling system 15, wheel assemblies 16, seat assemblies 17, and a transmission assembly 18. To clearly illustrate the technical solution of this application, terms such as... Figure 1 The front, rear, left, right, upper, and lower sides are shown. The power system 12 is at least partially mounted on the transmission assembly 18. The power system 12 provides driving force to the all-terrain vehicle 100. The body panel 13 is at least partially mounted on the frame assembly 11, forming a cabin between the body panel 13 and the frame assembly 11. The seat assembly 17 is at least partially mounted on the frame assembly 11 and is substantially located within the cabin. The heating system 14 and the cooling system 15 are at least partially mounted on the frame assembly 11, with the cooling system 15 at least partially connected to the power system 12. The wheel assembly 16 is at least partially connected to the transmission assembly 18. The transmission assembly 18 is at least partially connected to the frame assembly 11.

[0034] See Figure 2As one implementation, the heating system 14 is used to increase the temperature inside the cabin, thereby improving the riding experience for the driver and passengers. The heating system 14 can be configured as an air outlet 141 and a heat exchange device 142. The heat exchange device 142 is connected to the air outlet 141. After the air outlet 141 is activated, it supplies air to the heat exchange device 142, and the air absorbs at least a portion of the heat from the heat exchange device 142 before entering the cabin. The heat exchange device 142 is at least partially connected to the power system 12, thereby allowing the heat exchange device 142 to absorb heat from the power system 12. The power system 12 includes an engine 121. It is understood that the power system 12 can also be an electric motor or other device with driving force. The heat exchange device 142 is provided with a heat exchange water channel, a first liquid inlet 142a, and a first liquid outlet 142b. The first liquid outlet 142b is located at one end of the heat exchange water channel, and the first liquid inlet 142a is located at the other end of the heat exchange water channel. The power system 12 is provided with a hot water intake channel, a second liquid inlet, and a second liquid outlet. The second liquid outlet is located at one end of the hot water intake channel, and the second liquid inlet is located at the other end. A first liquid inlet pipe 143 is provided between the first liquid inlet 142a and the second liquid outlet, and a first liquid outlet pipe 144 is provided between the first liquid outlet 142b and the second liquid inlet. One end of the first liquid inlet pipe 143 is connected to the first liquid inlet 142a, and the other end of the first liquid inlet pipe 143 is connected to the second liquid outlet. Correspondingly, one end of the first liquid outlet pipe 144 is connected to the first liquid outlet 142b, and the other end of the first liquid outlet pipe 144 is connected to the second liquid inlet. Thus, the first liquid inlet pipe 143, the heat exchange channel, the first liquid outlet pipe 144, and the hot water intake channel form a basically closed flow loop, in which coolant is provided.

[0035] When the heating system 14 is running, coolant enters the power system 12 through the second inlet. After absorbing heat from the power system 12, the coolant exits the power system 12 through the second outlet. At least a portion of the coolant exiting the second outlet passes through the first inlet pipe 143 to the first inlet 142a, thus entering the heat exchange device 142. At the heat exchange device 142, the coolant transfers heat to the air output by the blower 141, then exits the heat exchange device 142 through the first outlet 142b, and finally returns to the power system 12 through the first outlet pipe 144. This arrangement allows the heat exchange device 142 to utilize the heat from the power system 12, thereby achieving energy savings.

[0036] The heating system 14 also includes a valve 145, which is installed on the first outlet pipe 144 and / or the first inlet pipe 143. The valve 145 controls the flow rate of the coolant entering the heat exchanger 142, thereby controlling the outlet air temperature of the heating system 14. Compared to traditional heating devices that place the heat control mechanism on the outlet device 141, placing the flow-regulating valve 145 outside the outlet device 141 saves installation space inside the outlet device 141, thus increasing the installation space for the heat exchanger 142. This increased volume of the heat exchanger 142 improves the heating effect.

[0037] See Figure 3 As one implementation, valve 145 can be configured as a two-way valve, which includes a first inlet end and a first outlet end. Coolant enters the two-way valve from the first inlet end and exits from the first outlet end. Valve 145 can be installed on the first inlet pipe 143, the first outlet pipe 144, or both. In this embodiment, valve 145 is installed on the first inlet pipe 143. When the heating system 14 is running, at least a portion of the coolant output from the second outlet enters the heat exchange device 142 through the two-way valve, thereby controlling the flow rate of coolant entering the heat exchange device 142.

[0038] See Figure 4 As an alternative implementation, valve 145 can be configured as a three-way valve, located on the first inlet pipe 143. The three-way valve includes a second inlet, a second outlet, and a third outlet. Coolant enters the three-way valve from the second inlet and exits from the second outlet and / or the third outlet. Both the second inlet and the second outlet are located on a flow path. A return pipe 146 is provided between the three-way valve and the power system 12. One end of the return pipe 146 is connected to the second inlet of the power system 12, and the other end is connected to the third outlet of the three-way valve. The return pipe 146 forms a flow path between the power system and the three-way valve, allowing coolant to flow. When the heating system 14 is running, at least a portion of the coolant output from the second outlet of the power system 12 is discharged to the three-way valve. Coolant enters the three-way valve from the second inlet and exits from the second outlet and / or the third outlet. The coolant output from the second outlet flows to the heat exchange device 142, and the coolant output from the third outlet flows back to the power system 12 through the return pipe 146. The flow rate of the coolant entering the heat exchange device 142 and flowing back to the power system 12 is controlled by a three-way valve, thereby regulating the temperature of the heating system 14.

[0039] See Figure 5 and Figure 6The air outlet device 141 includes a blower 141a, a first mounting portion 141b, a second mounting portion 141c, a blower duct 141d, and an outlet duct 141e. The blower 141a is at least partially disposed within the first mounting portion 141b. The heat exchange device 142 is at least partially disposed within the second mounting portion 141c. The blower duct 141d is located between the first mounting portion 141b and the second mounting portion 141c, with one end connected to the first mounting portion 141b and the other end connected to the second mounting portion 141c. The outlet duct 141e is connected to the second mounting portion 141c and is located on the side of the second mounting portion 141c away from the first mounting portion 141b. Along the longitudinal direction of the all-terrain vehicle 100, the seat assembly 17 is positioned behind the air outlet device 141. The first mounting portion 141b is located on the side of the air outlet duct 141e away from the seat assembly 17, thereby distancing the blower 141a from the driver and passengers, thus reducing the impact of noise on them. Furthermore, this arrangement makes the blower 141a more concealed and improves its waterproofness. A first channel for airflow is formed inside the first mounting portion 141b. An air inlet (not shown) is provided on one side of the second mounting portion 141c, and an air outlet 141ca is provided on the side of the second mounting portion 141c away from the air inlet. A heat exchange device 142 is located between the air inlet and the air outlet 141ca. An air duct for airflow is formed inside the blower duct 141d. The end of the air duct near the first mounting portion 141b communicates with the first channel, and the end of the air duct near the second mounting portion 141c communicates with the air inlet. The cross-sectional area of ​​the blower duct gradually increases from the first mounting part 141b to the second mounting part 141c. The air outlet duct 141e and the air outlet 141ca are connected. After the blower 141a starts running, it delivers air to the first channel. The air passes through the blower duct and reaches the second mounting part 141c. The air enters the second mounting part 141c from the air inlet and passes through the heat exchange device 142. The heat exchange device 142 heats the air. The hot air leaves the second mounting part 141c from the air outlet 141ca and enters the air outlet duct 141e. Finally, the air is output into the cabin after passing through the air outlet duct 141e.

[0040] Specifically, the second mounting part 141c includes a side panel 141cb and a base plate 141cc. The side panel 141cb and the base plate 141cc form a slot for inserting the heat exchange device 142, with the heat exchange device 142 at least partially located within the slot. The side panel 141cb includes a windward plate 141cd, a counter-wind plate 141ce, a first sealing plate 141cf, and a second sealing plate 141cg. An air inlet is provided on the windward plate 141cd, and an air outlet 141ca is provided on the counter-wind plate 141ce. The ratio of the area of ​​the air inlet to the area of ​​the windward plate 141cd is greater than or equal to 0.8 and less than or equal to 1, thereby allowing the air input from the blower duct 141d to cover a larger area of ​​the heat exchange device 142, fully utilizing the heat exchange device 142, increasing airflow, and thus improving heat exchange efficiency. The ratio of the area of ​​the air outlet 141ca to the area of ​​the counter-wind plate 141ce is greater than or equal to 0.8 and less than or equal to 1, making full use of the heat exchange device 142 to increase the air volume and thus improve the heat exchange efficiency.

[0041] As one implementation, the air outlet duct 141e is provided with an air outlet 141f, and at least part of the air in the air outlet duct 141e is output from the air outlet 141f. The wall of the air outlet duct 141e away from the blower 141a is a guide wall 141ea, which is connected to the anti-wind plate 141ce, and the guide wall 141ea is arc-shaped. With the above arrangement, air enters the air outlet duct 141e from the air outlet hole 141ca and moves along the guide wall 141ea towards the air outlet 141f, thereby reducing wind resistance. The wall of the air outlet duct 141e near the blower 141a is a connecting wall 141eb, which is at least partially connected to the first sealing plate 141cf, which is at least partially connected to the reinforcing plate 141ec, and which is at least partially connected to the connecting wall 141eb. A triangular region is formed between the first sealing plate 141cf, the connecting wall 141eb, and the reinforcing plate 141ec. This arrangement increases the stability of the air outlet duct 141e. A first reinforcing plate 141ed is provided within this triangular region, with its edge fixedly connected to the inner wall of the triangular region, further stabilizing the air outlet duct 141e. Furthermore, a receiving space is also formed between the first mounting portion 141b and the reinforcing plate 141ec, within which a second reinforcing plate 141ee is provided. One side of the second reinforcing plate 141ee is fixedly connected to the first mounting portion 141b, and the other side is fixedly connected to the reinforcing plate 141ec. The second reinforcing plate 141ee increases the rigidity of the air outlet duct 141e, preventing deformation of the air outlet duct 141e when the all-terrain vehicle 100 vibrates.

[0042] As one implementation, a limiting plate 141ef is provided on the air outlet duct 141e. One end of the limiting plate 141ef is connected to the air outlet duct 141e via a connector. One end of the limiting plate 141ef has an extension end. The end of the heat exchange device 142 away from the base plate 141cc abuts against the extension end of the limiting plate 141ef to prevent the heat exchange device 142 from dislodging from the slot. The number of limiting plates can be one, two, or more. In this application, the number of limiting plates 141ef is set to one. Specifically, the limiting plate 141ef abuts against the middle position of the end of the heat exchange device 142 away from the base plate 141cc. Further, the limiting plate 141ef is provided with a limiting groove, and a limiting block is provided on the contact surface between the heat exchange device 142 and the extension end of the limiting plate 141ef. The limiting block can engage with the limiting groove. When the limiting block engages with the limiting groove, the limiting block is at least partially located within the limiting groove. The limiting groove and limiting block prevent the limiting plate 141ef from rotating relative to the connecting member, thereby improving the stability of the limiting plate 141ef. The limiting plate 141ef prevents the heat exchange device 142 from moving out of the slot when the all-terrain vehicle 100 vibrates.

[0043] See Figure 7 In this embodiment, a first air conditioning pipe 141fa and a second air conditioning pipe 141fb are connected to the air outlet 141f. The end of the first air conditioning pipe 141fa away from the air outlet 141f is the first air conditioning vent 141fc, and the end of the second air conditioning pipe 141fb away from the air outlet 141f is the second air conditioning vent 141fd. The all-terrain vehicle 100 also includes an instrument panel (not shown in the figure). The cabin includes a first cabin section and a second cabin section. The first cabin section is located on the left side of the all-terrain vehicle 100, and the second cabin section is located on the right side of the all-terrain vehicle 100. Both the first air conditioning vent 141fc and the second air conditioning vent 141fd are located on the instrument panel. Specifically, the first air conditioning vent 141fc is located on the side of the instrument panel closer to the first cabin section, thereby increasing the heating effect of the heating system 14 on the first cabin section. The second air conditioning vent 141fd is located on the side of the instrument panel closer to the second cabin section, thereby increasing the heating effect of the heating system 14 on the second cabin section. Along the vertical direction of the all-terrain vehicle 100, the air outlet 141f is located at the upper end of the air outlet duct 141e, with the opening of the air outlet 141f facing upwards. This facilitates the upward extension of the first air conditioning duct 141fa and the second air conditioning duct 141fb, reducing their length and thus saving installation space on the all-terrain vehicle 100. Both the first air conditioning duct 141fa and the second air conditioning duct 141fb are made of corrugated pipes, which can be deformed at will, facilitating the arrangement of the first air conditioning duct 141fa and the second air conditioning duct 141fb.

[0044] See Figure 8 and Figure 9In one implementation, the heat exchange device 142 includes an upper water chamber 142c, a lower water chamber 142d, and several heat-conducting elements 142e. The heat-conducting elements 142e are disposed between the upper water chamber 142c and the lower water chamber 142d. One end of the heat-conducting element 142e is fixedly connected to the upper water chamber 142c, and the other end is fixedly connected to the lower water chamber 142d. The upper water chamber 142c has a first flow chamber 142ca for circulating coolant, the lower water chamber 142d has a second flow chamber 142da for circulating coolant, and the heat-conducting elements 142e have a second channel for circulating coolant. The heat-conducting elements 142e are arranged at approximately equal intervals. The upper water chamber 142c and the lower water chamber 142d are arranged approximately parallel to each other, and the heat-conducting elements 142e and the upper water chamber 142c are arranged approximately perpendicular to each other, i.e., the heat-conducting elements 142e and the lower water chamber 142d are also arranged approximately perpendicular to each other. Both the first liquid inlet 142a and the first liquid outlet 142b are located on the side of the upper water chamber 142c away from the heat-conducting component 142e. Specifically, the first liquid inlet 142a communicates with the first flow chamber 142ca, and the first liquid outlet 142b communicates with the first flow chamber 142ca. A partition 142f is fixedly connected inside the upper water chamber 142c. Specifically, the partition 142f is located in the middle of the upper water chamber 142c, between the first liquid inlet 142a and the first liquid outlet 142b. The partition 142f divides the first flow chamber 142ca into an inlet chamber 142cb and an outlet chamber 142cc. The first liquid inlet 142a communicates with the inlet chamber 142cb, and the first liquid outlet 142b communicates with the outlet chamber 142cc. The heat-conducting component 142e includes a first heat-conducting component 142ea and a second heat-conducting component 142eb. The second channel of the first heat-conducting element 142ea is connected to the liquid inlet chamber 142cb of the upper water chamber 142c, and the second channel of the second heat-conducting element 142eb is connected to the liquid outlet chamber 142cc of the upper water chamber 142c. The liquid inlet chamber 142cb, the second channel of the first heat-conducting element 142ea, the second flow chamber 142da, the second channel of the second heat-conducting element 142eb, and the liquid outlet chamber 142cc constitute a heat exchange channel. See also Figure 10 When the coolant passes through the heat exchange device 142, the coolant in the first inlet pipe 143 enters the inlet chamber 142cb from the first inlet port 142a, and then flows along the second channel of the first heat conductor 142ea to the second flow chamber 142da. The coolant in the second flow chamber 142da flows through the second channel of the second heat conductor 142eb to the outlet chamber 142cc, and then leaves the heat exchange device 142 through the first outlet port 142b.

[0045] See Figure 9As one implementation, the heat exchange device 142 further includes a protective plate 142g, which is disposed between the upper water chamber 142c and the lower water chamber 142d. Specifically, the protective plate 142g includes a first protective plate and a second protective plate, which are substantially parallel. One end of the first protective plate is connected to one end of the upper water chamber 142c, and the other end of the first protective plate is connected to one end of the lower water chamber 142d. One end of the second protective plate is connected to the other end of the upper water chamber 142c, and the other end of the second protective plate is connected to the other end of the lower water chamber 142d. The heat-conducting element 142e is located between the first and second protective plates. The first protective plate, the upper water chamber 142c, the second protective plate, and the lower water chamber 142d form a protective frame that protects the heat-conducting element 142e. Specifically, the protective plate 142g is fixedly connected to the upper water chamber 142c by welding, and the protective plate 142g is fixedly connected to the lower water chamber 142d by welding. In this embodiment, both ends of the upper water chamber 142c and the lower water chamber 142d are fixedly connected with clamping members 142h. The clamping members 142h are used to clamp the protective plate 142g onto the upper water chamber 142c and the lower water chamber 142d, thereby facilitating the welding of the protective plate 142g.

[0046] See Figure 9 and Figure 11 As one implementation, fins 142k are provided between the heat-conducting elements 142e and between the heat-conducting elements 142e and the protective plate 142g. The fins 142k increase the air's heat-receiving area, improving heating efficiency. The fins 142k are wavy. The length of the fins 142k is adapted to the length of the heat-conducting elements 142e; that is, the distance between the upper water chamber 142c and the lower water chamber 142d is a first distance, and the ratio of the length of the fins 142k to the first distance is greater than or equal to 0.9 and less than or equal to 1.

[0047] See Figure 11The cross-section of the heat-conducting component 142e can be rectangular, elliptical, rhomboid, or other shapes, and can be adjusted according to actual conditions. In this embodiment, the cross-sections of both the heat-conducting component 142e and the second channel are rectangular, and the circumferential wall thickness t of the heat-conducting component 142e is basically equal. The length of the long side of the cross-section of the heat-conducting component 142e corresponds to the width W of the heat-conducting component 142e, the length of the short side of the cross-section of the heat-conducting component 142e corresponds to the height B of the heat-conducting component 142e, and the distance between two adjacent heat-conducting components 142e is D. The wider the heat-conducting element 142e, the larger the air heating surface, and the better the heating effect of the heating system 14; the larger the spacing of the heat-conducting elements 142e, the smaller the wind resistance, and the larger the air volume of the heating system 14, but correspondingly, the fewer the number of heat-conducting elements 142e, the worse the heating effect of the heating system 14; the smaller the wall thickness of the heat-conducting element 142e, the better the efficiency of heat transfer from the coolant to the outer wall of the heat-conducting element 142e; the greater the height of the heat-conducting element 142e, the greater the wind resistance, and the smaller the air volume of the heating system 14. In one implementation, the ratio of the height B of the heat-conducting element 142e to its wall thickness t is greater than or equal to 3.8 and less than or equal to 8.2; the ratio of the width W of the heat-conducting element 142e to its wall thickness t is greater than or equal to 76.9 and less than or equal to 136.4; and the ratio of the spacing D of the heat-conducting elements 142e to its wall thickness t is greater than or equal to 13.8 and less than or equal to 18.2. With these settings, the heating system 14 combines the advantages of large airflow and good heating effect. In this embodiment, the wall thickness t of the heat-conducting element 142e is 0.22 mm. Under the premise that the width W and height B of the heat-conducting element 142e are constant, the airflow is maximized as much as possible. The width W of the heat-conducting element 142e is 26 mm, the height B is 1.4 mm, and the spacing D is 4 mm.

[0048] See Figure 13 The heating system 14 also includes multiple foot-blowing pipes 147, which are arranged on the left and right sides of the air outlet duct 141e. Each foot-blowing pipe 147 is at least partially connected to the air outlet duct 141e, and the foot-blowing pipes 147 and the air outlet duct 141e are in communication, forming an air outlet assembly. Air within the air outlet duct 141e is output from the foot-blowing pipes 147 and / or the air outlet 141f. It is understood that one, two, or more foot-blowing pipes 147 can be used.

[0049] As one implementation, two foot-blowing pipes 147 are provided, including a first foot-blowing pipe located to the left of the air outlet pipe 141e and a second foot-blowing pipe located to the right of the air outlet pipe 141e. The all-terrain vehicle 100 includes a reference plane 101 extending substantially along the longitudinal direction of the all-terrain vehicle 100, and the left and right sides of the all-terrain vehicle 100 are substantially symmetrical about the reference plane 101. The heating system 14 passes at least partially through the reference plane 101, thereby facilitating the arrangement of the foot-blowing pipes 147, and thus making the lengths of the first and second foot-blowing pipes substantially the same.

[0050] See Figure 7 The first foot-blowing pipe has its outlet located on the left side of the cockpit, away from the air outlet, while the second foot-blowing pipe has its outlet located on the right side of the cockpit. Specifically, the first foot-blowing pipe's outlet is located on the right side of the first cockpit section, and the second foot-blowing pipe's outlet is located on the left side of the second cockpit section. This shortens the length of the foot-blowing pipe 147, reducing heat loss during the transport of hot air within the foot-blowing pipe 147 and resulting in a higher air temperature output from the foot-blowing pipe 147.

[0051] As an optional implementation, to enhance the airflow effect of the foot-blowing pipe 147, the end of the foot-blowing pipe 147 away from the air outlet pipe 141e can have a branched structure. Specifically, the foot-blowing pipe 147 includes a main body 147b and several branch pipes 147a. One end of the main body 147b is connected to the air outlet pipe 141e, and the other end of the main body 147b is connected to the branch pipes 147a. Further, the end of the main body 147b away from the air outlet pipe 141e is provided with two branch pipes 147a. A floor (not shown in the figure) is provided on the frame assembly 11. When the driver's and passenger's feet are on the floor, the branch pipes 147a divide the single stream of hot air in the foot-blowing pipe 147 into multiple streams of hot air, allowing the hot air to diffuse and cover a larger area of ​​the floor, thereby improving the heating effect. In addition, a reinforcing zone is formed between the branch pipes 147a, thereby increasing the strength of the foot-blowing pipe 147, improving the stability of the foot-blowing pipe 147, and effectively preventing damage to the foot-blowing pipe 147.

[0052] See Figure 2The cooling system 15 is used to cool the engine 121 during operation, preventing the engine 121 from overheating. The cooling system 15 includes a radiator 151. The radiator 151 has a third water channel, a third inlet, and a third outlet. The third inlet is located at one end of the third water channel, and the third outlet is located at the other end. The third inlet and the third water channel are connected, as are the third outlet and the third water channel. The third outlet and the second inlet are connected, and the third inlet and the second outlet are also connected. Alternatively, the cooling system 15 may also include a second inlet pipe 152 and a second outlet pipe 153. One end of the second inlet pipe 152 is connected to the second outlet of the power system 12, and the other end is connected to the third inlet of the radiator 151. One end of the second outlet pipe 153 is connected to the second inlet of the power system 12, and the other end is connected to the third outlet of the radiator 151. At this point, the third water channel, the second inlet pipe 152, the second outlet pipe 153, and the hot water intake channel constitute a basically closed heat dissipation circuit, within which coolant is contained. (See also...) Figure 3 and Figure 4 When the cooling system 15 is running, at least a portion of the coolant output from the second outlet of the power system 12 is discharged to the radiator 151 through the second inlet pipe 152. The coolant transfers at least a portion of its heat to the outside air in the radiator 151 and returns to the power system 12 through the second outlet pipe 153 to continue cooling the power system 12. The radiator 151 dissipates the heat into the air. In this embodiment, the coolant output from the second outlet of the power system 12 flows to the radiator 151 and / or the heat exchange device 142.

[0053] See Figure 2 In one implementation, the radiator 151 is at least partially connected to the frame assembly 11. Alternatively, a bracket 111 is fixedly connected to the front end of the frame assembly 11. The radiator 151 is mounted on the bracket 111, and a buffer pad 112 is provided between the bracket 111 and the radiator 151. The lower side of the radiator 151 at least partially abuts against the buffer pad 112. Specifically, the buffer pad 112 can be made of rubber or sponge. When the all-terrain vehicle 100 experiences bumps, the buffer pad 112 can effectively reduce the impact on the radiator 151, thus protecting the radiator 151.

[0054] In this embodiment, the heat dissipation system 15 is at least partially connected to the heating system 14. As one implementation, the end of the second inlet pipe 152 furthest from the radiator 151 is connected to the second outlet of the power system 12; the end of the second outlet pipe 153 furthest from the radiator 151 is connected to the second inlet of the power system 12; the end of the first inlet pipe 143 furthest from the heat exchanger 142 is connected to the second inlet pipe 152 and communicates with it; and the end of the first outlet pipe 144 furthest from the heat exchanger 142 is connected to the second outlet pipe 153 and communicates with it. With this arrangement, the length and volume of the first inlet pipe 143 and the first outlet pipe 144 can be shortened, thereby reducing the weight of the all-terrain vehicle 100.

[0055] In another implementation, the end of the first inlet pipe 143 furthest from the heat exchanger 142 is connected to the second outlet of the power system 12; the end of the first outlet pipe 144 furthest from the heat exchanger 142 is connected to the second inlet of the power system 12; the end of the second inlet pipe 152 furthest from the radiator 151 is connected to and communicates with the first inlet pipe 143; and the end of the second outlet pipe 153 furthest from the radiator 151 is connected to and communicates with the first outlet pipe 144. With this arrangement, the length and volume of the second inlet pipe 152 and the second outlet pipe 153 can be shortened, thereby reducing the weight of the all-terrain vehicle 100.

[0056] In another implementation, the end of the second inlet pipe 152 furthest from the radiator 151 is connected to the second outlet of the power system 12; the end of the first outlet pipe 144 furthest from the heat exchanger 142 is connected to the second inlet of the power system 12; the end of the first inlet pipe 143 furthest from the heat exchanger 142 is connected to the second inlet pipe 152 and communicates with the second inlet pipe 152; and the end of the second outlet pipe 153 furthest from the radiator 151 is connected to the first outlet pipe 144 and communicates with the second outlet pipe 153. With this arrangement, the length and volume of both the first inlet pipe 143 and the second outlet pipe 153 can be shortened simultaneously, thereby reducing the weight of the all-terrain vehicle 100.

[0057] In another implementation, the end of the first inlet pipe 143 furthest from the heat exchanger 142 is connected to the second outlet of the power system 12; the end of the second outlet pipe 153 furthest from the radiator 151 is connected to the second inlet of the power system 12; the end of the second inlet pipe 152 furthest from the radiator 151 is connected to and communicates with the first inlet pipe 143; and the end of the first outlet pipe 144 furthest from the heat exchanger 142 is connected to and communicates with the second outlet pipe 153. With this arrangement, the length and volume of both the second inlet pipe 152 and the first outlet pipe 144 can be shortened simultaneously, thereby reducing the weight of the all-terrain vehicle 100.

[0058] As one implementation, the heating system 14 also includes electric heating elements (not shown in the figure), which are PTC heaters and are mounted on the air outlet device. Through this configuration, the heating system 14 can freely switch heat sources. Specifically, when the temperature of the power system 12 is low, the electric heating elements heat the air supplied to the blower 141a; when the temperature of the power system 12 is high, the heat exchange device 142 heats the air supplied to the blower 141a. Furthermore, the electric heating elements can be positioned on the side of the heat exchange device 142 closer to the blower 141a, or on the side of the heat exchange device 142 farther from the blower 141a.

[0059] As one implementation, the heating system 14 can also be configured as an air outlet device 141 and an electric heating element. The electric heating element is connected to the air outlet device 141. After the air outlet device 141 is activated, it supplies air to the electric heating element, and the air absorbs at least part of the heat from the electric heating element before entering the cabin. With this configuration, the heating system 14 can heat the cabin when the power system 12 is at a low temperature.

[0060] See Figure 15 The transmission assembly 18 includes a front axle 181 and a rear axle 182. The front axle 181 extends substantially along the left-right direction of the all-terrain vehicle 100, and the front axle 181 and the rear axle 182 are substantially parallel. The blower 141a includes a fan wheel 141aa, with an axis extending along the left-right direction of the all-terrain vehicle 100 through the rotation center of the fan wheel 141aa. The distance from the axis of the front axle 181 to the axis of the rear axle 182 is L. The all-terrain vehicle 100 has a first plane perpendicular to the vertical direction, and the axes of the front axle 181 and the rear axle 182 are substantially located on the first plane. The axis of the fan wheel 141aa is substantially parallel to the first plane. The distance from the axis of the fan wheel 141aa to the first plane is H, and the ratio of H to L is greater than or equal to 0.14 and less than or equal to 0.27. As one implementation, L is 1900mm-2100mm, and H is 300mm-500mm. At this point, the all-terrain vehicle 100 exhibits good driving stability, and the air outlet device 141 and heat exchange device 142 are relatively high, providing good waterproofing. As one implementation method, L is set to 1930mm-2050mm, and H is set to 350mm-450mm, meaning the ratio of H to L is greater than or equal to 0.17 and less than or equal to 0.24. In this embodiment, L is set to 1950mm, and H is set to 395mm, meaning the ratio of H to L is 0.20.
