[0043] 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.

[0044] like Figure 1 and Figure 2 An all-terrain vehicle 100 is shown, and the all-terrain vehicle 100 includes a frame 11, a body covering 12, a running assembly 13 and a power assembly 14. The frame 11 constitutes the basic framework of the all-terrain vehicle 100, and the frame 11 is used to provide support for other components of the all-terrain vehicle 100. The body covering 12 is at least partially located on the frame 11, and the body covering 12 is used to protect the internal parts of the all-terrain vehicle 100. The body covering 12 mainly refers to plastic parts located on the outside of the all-terrain vehicle 100. The running assembly 13 is at least partially located below the frame 11, and the running assembly 13 includes a front wheel 131 located at the front of the all-terrain vehicle 100 and a rear wheel 132 located at the rear of the all-terrain vehicle 100. The power assembly 14 is used to provide power to the all-terrain vehicle 100 to drive the all-terrain vehicle 100 to move, and the power assembly 14 is transmission-connected to the front wheel 131 and / or the rear wheel 132. In order to clearly illustrate the technical solution of the present application, it is also defined as follows: Figure 1 The front, rear, upper and lower sides shown, as well as Figure 2 It is understood that the length direction in the embodiment of the present application refers to the front-to-back direction of the all-terrain vehicle 100, the width direction refers to the left-to-right direction of the all-terrain vehicle 100, and the height direction refers to the up-down direction of the all-terrain vehicle 100.

[0045] like Figure 1 As shown, the all-terrain vehicle 100 further includes a heat dissipation assembly 15, which is located at the front of the all-terrain vehicle 100 and includes a radiator 151 (see Fig.17 ), the power assembly 14 includes an engine 141, and a radiator 151 is connected to the engine 141 through a pipeline, and the pipeline is filled with coolant, so that the heat generated by the operation of the engine 141 is transferred to the radiator 151 through the coolant in the pipeline, and the heat is transferred to the outside through the radiator 151, thereby realizing the heat dissipation function of the engine 141. Since the existing radiator 151 is usually located at the front of the all-terrain vehicle 100 near the front of the vehicle along the length direction of the all-terrain vehicle 100, and the radiator 151 is vertically arranged, so that the radiator 151 is in the maximum windward area, which is convenient for the heat dissipation of the radiator 151, but this arrangement method causes the wading height of the all-terrain vehicle 100 to be low. When the all-terrain vehicle 100 is driving on a muddy road section or a wading road section, the radiator 151 is easily unable to work normally due to silt accumulation.

[0046] As an implementation, the body cover 12 includes a front cover 121 located at the front of the all-terrain vehicle 100, the front cover 121 is located above the front wheel 131, the all-terrain vehicle 100 also includes a steering assembly 16, the steering assembly 16 includes a steering handle 161 located at the upper part of the all-terrain vehicle 100 along the height direction of the all-terrain vehicle 100, and the front cover 121 is also located in front of the steering handle 161. In order to improve the wading performance of the all-terrain vehicle 100, the heat dissipation assembly 15 of the present application is at least partially located above the front cover 121 and fixedly connected to the frame 11, and the heat dissipation assembly 15 is also located in front of the steering handle 161. Further, the body cover 12 also includes an instrument cover 122, the instrument cover 122 is used to install the vehicle instrument, the vehicle instrument is used to display the status information and driving information of the all-terrain vehicle 100, the instrument cover 122 is at least partially located in front of the steering assembly 16 and above the front cover 121, and the heat dissipation assembly 15 is also at least partially located in front of the instrument cover 122. Through the above arrangement, the height of the heat dissipation assembly 15 from the ground is higher, thereby improving the wading height of the all-terrain vehicle 100, so that when the all-terrain vehicle 100 passes through a wading section, the radiator 151 will not be in danger of being blocked by mud and sand, thereby improving the passability of the all-terrain vehicle 100 in wading sections and muddy sections.

[0047] like Figure 2As shown, the power assembly 14 also includes a transmission 142, which is connected to the engine 141 in a transmission manner to change the speed of the engine 141, increase or decrease the torque of the engine 141, and enable the all-terrain vehicle 100 to obtain a power output mode that is more suitable for the use scenario. The transmission 142 includes a transmission air intake pipe 1421 and a transmission exhaust pipe 1422, which are mainly used to dissipate heat for the transmission 142, that is, natural wind with a relatively low temperature enters the transmission 142 through the transmission air intake pipe 1421 and undergoes heat exchange with the transmission 142 to become hot air. After the heat exchange is completed, the hot air is discharged through the transmission exhaust pipe 1422, thereby reducing the operating temperature of the transmission 142. The transmission air intake pipe 1421 includes a transmission air intake port 1421a, and the transmission exhaust pipe 1422 includes a transmission exhaust port 1422a. In the embodiment of the present application, the speed change air inlet 1421a and the speed change air outlet 1422a are located behind the heat dissipation assembly 15, and the speed change air inlet 1421a and the speed change air outlet 1422a are also at least partially located behind the instrument surface cover 122, and when viewed along the width direction of the all-terrain vehicle 100, the speed change air inlet 1421a, the speed change air outlet 1422a and the steering assembly 16 at least partially overlap. Through the above arrangement, the arrangement position of the speed change air inlet 1421a and the speed change air outlet 1422a can be improved, and the arrangement position of the speed change air inlet 1421a and the speed change air outlet 1422a can be prevented from being too close to the ground, thereby avoiding the risk of water ingress into the speed change air inlet 1421a and the speed change air outlet 1422a when passing through a wading section, thereby preventing the transmission 142 from being damaged, thereby improving the wading height of the all-terrain vehicle 100 and improving the passability of the all-terrain vehicle 100.

[0048] like Figure 2 and Figure 3As shown, in this embodiment, the power assembly 14 also includes an air filter 143, which is at least partially located above the engine 141 and communicated with the engine 141. The air filter 143 is mainly used to filter the air and deliver the filtered air to the engine 141 to assist the normal operation of the engine 141. The air filter 143 includes an air filter intake pipe 1431, and the air filter intake pipe 1431 includes an air filter intake port 1431a. The air filter intake port 1431a is at least partially located above the instrument surface cover 122. The air filter intake port 1431a is also at least partially located in front of the steering handle 161. In this application, The steering assembly 16 is located behind the heat dissipation assembly 15, the air filter inlet 1431a is located between the heat dissipation assembly 15 and the steering assembly 16, and the air filter inlet 1431a is facing the rear of the all-terrain vehicle 100, that is, the air filter inlet 1431a is basically facing the steering assembly 16, thereby improving the layout position of the air filter inlet 1431a, avoiding water ingress into the air filter inlet 1431a when the all-terrain vehicle 100 passes through a wading section, causing water ingress and damage to the engine 141, thereby increasing the wading height of the all-terrain vehicle 100, improving the passability of the all-terrain vehicle 100, and also improving the safety of the all-terrain vehicle 100.

[0049] The power assembly 14 also includes a vent pipe 144, which is mainly used to connect the front axle and the rear axle of the all-terrain vehicle 100 with the outside world, and balance the air pressure inside and outside the front axle and the rear axle by inhaling or exhausting air. Specifically, the vent pipe 144 includes a vent 1441. In this embodiment, one end of the vent pipe 144 is fixedly connected to the instrument surface cover 122, and the vent 1441 is arranged at one end of the vent pipe 144 close to the instrument surface cover 122, so as to improve the arrangement position of the vent 1441, and prevent water from entering the vent pipe 144 through the vent 1441 and flowing to the front axle and the rear axle when the all-terrain vehicle 100 passes through the wading section, thereby avoiding affecting the normal operation of the front axle and the rear axle, thereby improving the wading height of the all-terrain vehicle 100 and improving the passability of the all-terrain vehicle 100 in the wading section.

[0050] like Figure 1As shown, in this embodiment, the all-terrain vehicle 100 further includes a saddle assembly 17 and a cargo box assembly 18. The saddle assembly 17 is at least partially located above the engine 141 and the transmission 142. The saddle assembly 17 is mainly used to carry the driver. The cargo box assembly 18 is located behind the saddle assembly 17. The cargo box assembly 18 is also at least partially located above the frame 11 and fixedly connected to the frame 11. Observing along the width direction of the all-terrain vehicle 100, the contact point between the rear wheel 132 and the ground is defined as the grounding point P1, and a plane perpendicular to the line connecting the grounding point P1 and the rotation center of the rear wheel 132 and passing through the grounding point P1 is defined as the horizontal plane 101. It can be understood that according to the shape of the rear wheel 132, the tangent point between the rear wheel 132 and the ground is basically the grounding point P1. When the air pressure of the rear wheel 132 is insufficient, the rear wheel 132 may be in line contact with the ground, that is, multiple grounding points P1 are formed, or the ground is in a non-planar state. At this time, the grounding point P1 is the lowest point where the rear wheel 132 contacts the ground. The ratio of the minimum distance H1 between the cargo box assembly 18 and the horizontal plane 101 to the height H2 of the rear wheel is 0.95 to 1.4. In the present application, the ratio of the minimum distance H1 between the cargo box assembly 18 and the horizontal plane 101 to the height H2 of the rear wheel is 1.1, so that the cargo box assembly 18 is prevented from entering with water by increasing its height. Since several electrical components may be arranged near the cargo box assembly 18, increasing the height of the cargo box assembly 18 can further increase the wading height of the whole all-terrain vehicle 100. In addition, the driver can also move the center of gravity of the driver's body backward by sitting in the cargo box assembly 18 during driving, which is more conducive to the driver's control of the all-terrain vehicle 100.

[0051] like Figure 4As shown, the body cover 12 also includes foot pedals 123, which are located on both sides of the engine 141 along the width direction of the all-terrain vehicle 100, and the foot pedals 123 are used to support the driver's feet when the driver is in a normal riding posture. The all-terrain vehicle 100 also includes a foot pedal assembly 19, which is located behind the foot pedal 123. The foot pedal assembly 19 is used to support the driver's feet when the driver is in a special riding posture. Two foot pedals 123 and two foot pedal assemblies 19 are each provided, and the two foot pedals 123 and the two foot pedal assemblies 19 are distributed along the width direction of the all-terrain vehicle 100, and the minimum distance H3 between the rear foot pedal 191 and the horizontal plane 101 is greater than the minimum distance H4 between the foot pedal 123 and the horizontal plane 101. It is understandable that the driver has two riding postures when driving the all-terrain vehicle 100, namely, sitting riding and standing riding. When the driver is in the sitting riding posture, the driver sits on the saddle assembly 17 and steps on the pedals 123 with both feet. This riding posture is a common riding posture for the driver to drive the all-terrain vehicle 100. When the all-terrain vehicle 100 passes through a wading section, the driver's sitting riding posture may easily cause the driver's feet to be submerged by the water flow, resulting in a poor driving experience for the driver. At this time, the driver can change to a standing riding posture. When in the standing riding posture, the driver steps on the rear pedals 191 with both feet, thereby preventing the driver's feet from being submerged by the water flow, thereby improving the driver's driving experience. Further, during the climbing process of the all-terrain vehicle 100, if the driver is in the sitting riding posture, the driver is prone to danger due to the unstable center of gravity caused by the body leaning back during the climbing process of the all-terrain vehicle 100. The standing riding posture can also make the driver's center of gravity more forward, thereby avoiding danger to the driver.

[0052] like Figure 4 , Figure 5 and Figure 6 As shown, the pedal bracket 192 is fixedly connected to the main frame 111 and extends outwardly in the width direction of the all-terrain vehicle 100. The pedal bracket 192 is used to fix the rear pedal 191. The rear pedal 191 is located above the pedal bracket 192 and is fixedly connected to the pedal bracket 192. There are two pedal brackets 192 and two rear pedals 191, and the two pedal brackets 192 and the two rear pedals 191 are distributed in the width direction of the all-terrain vehicle 100. The body cover 12 also includes a footrest 123. When viewed from the height direction of the all-terrain vehicle 100, the footrest 123 and the rear pedal 191 are distributed in the length direction of the all-terrain vehicle 100. The footrest 123 is located in front of the rear pedal 191. When the driver rides in a sitting position, the footrest 123 is used for the driver to place his feet. The rear pedal 191 is also located below the saddle assembly 17. The rear pedal 191 is used for the driver's feet to step on when the driver is in a standing riding position, thereby providing support for the driver. It can be understood that the “outward” mentioned above refers to the pedal bracket 192 extending in a direction away from the longitudinal plane 105 .

[0053] As an implementation method, when the driver is in a standing riding posture, the driver steps on the rear pedal 191, and the center of gravity of the driver leans forward. In order to increase the wading height of the driver's feet, a reference plane 102 is defined, and the rear pedal 191 basically extends along the reference plane 102. It can be understood that, as Figure 4 As shown, in the present embodiment, when the front wheel 131 and the rear wheel 132 are both located on the horizontal plane 101, an angle β is formed between the reference plane 102 and the horizontal plane 101, and the angle β is 15° to 40°. More specifically, the angle β is 22° to 33°. In the present application, the angle β is 27°. Through the above arrangement, it can be avoided that the angle β is too large or too small, so that when the driver is in a standing riding posture, the driver's feet are not tightly fitted with the rear pedal 191, resulting in unstable stepping of the driver, and the driving safety of the driver can be improved during the driving of the all-terrain vehicle 100. In addition, the angle β is more ergonomic, making the driver's stepping more comfortable, thereby improving the driving comfort of the driver.

[0054] Specifically, the minimum distance between the rear pedal 191 and the horizontal plane 101 is defined as the pedal height H3, and the minimum distance between the pedal board 123 and the horizontal plane 101 is defined as the pedal height H4. The pedal height H3 is greater than the pedal height H4, so that the rear pedal 191 can be located above the pedal board 123. When the all-terrain vehicle 100 passes through a muddy section or a wading section, the driver can step on the rear pedal 191 to raise the driver's foot position, thereby preventing the driver's feet from being submerged by the water flow. When both the front wheel 131 and the rear wheel 132 are located on the horizontal plane 101, the minimum distance between the rear pedal 191 and the horizontal plane 101 is 54 cm to 72 cm. In the present application, the minimum distance between the rear pedal 191 and the horizontal plane 101 is 60 cm. Furthermore, in the present application, the air filter inlet 1431a is located at the uppermost end of the all-terrain vehicle 100, and thus the distance between the uppermost end of the air filter inlet 1431a and the horizontal plane 101 is defined as the vehicle height H5, and the ratio of the pedal height H3 to the vehicle height H5 is 0.35 to 0.53, thereby preventing the pedal height H3 from being too low and causing the driver's feet to be submerged in water when the driver steps on the rear pedal 191, and preventing the pedal height H3 from being too high and making it inconvenient for the driver to step on the rear pedal 191, thereby improving the human-computer interaction of the all-terrain vehicle 100.

[0055] As an implementation, the all-terrain vehicle 100 includes a first posture and a second posture, and the state when the front wheel 131 and the rear wheel 132 of the all-terrain vehicle are both located on the horizontal plane 101 is defined as the first posture of the all-terrain vehicle 100, and the pedal 123 extends substantially along the first preset plane 107. When the all-terrain vehicle 100 is in the first posture, the first preset plane 107 is substantially parallel to the horizontal plane 101; a reference plane 102 is defined, and the rear pedal 191 is substantially extended along the reference plane 102; the state when the all-terrain vehicle 100 moves to the reference plane 102 being substantially parallel to the horizontal plane 101 is defined as the second posture of the all-terrain vehicle 100; when the all-terrain vehicle 100 is in the second posture, the distance H6 between the reference plane 102 and the horizontal plane 101 is 67 cm to 83 cm. In the present application, the distance H6 between the reference plane 102 and the horizontal plane 101 is 75 cm. Through the above arrangement, when the ATV 100 is in the second posture, the distance H6 between the rear pedal 191 and the horizontal plane 101 is greater than the pedal height H3 when the ATV 100 is in the first posture, that is, when the ATV 100 is in the second posture, the wading height is at the maximum state, so that the wading height of the ATV 100 can be further improved, and when the ATV 100 passes through the wading section, the driver's feet are prevented from wading, thereby improving the driver's driving experience. It can be understood that when the ATV 100 is in the first posture, the driver can be in the aforementioned sitting riding posture or standing riding posture, and when the ATV 100 is in the second posture, the driver is basically in the standing riding posture. In addition, when the ATV 100 is in the second posture, the driver can also ride in a special sitting posture, that is, the cargo box assembly 18 can be provided for the driver to sit as described above, so as to be more conducive to the driver's control of the ATV 100. It can be understood that the distance between a certain component on the all-terrain vehicle 100 and the horizontal plane 101 is the wading height of the component. By increasing the wading heights of multiple components, the wading height of the entire vehicle can be increased.

[0056] like Figure 6As shown, in this embodiment, the rear pedal 191 is also provided with a plurality of anti-skid teeth 1911, which protrude upward substantially along the height direction of the all-terrain vehicle 100, and the anti-skid teeth 1911 can catch the sole of the driver's shoe. When the driver is in a standing riding posture, the driver mainly maintains the stability of the body by both hands and feet to avoid falling off the all-terrain vehicle 100, and the anti-skid teeth 1911 can prevent the driver's feet from slipping off the rear pedal 191, causing danger to the driver. Furthermore, the rear pedal 191 is also provided with a weight-reducing hole 1912, which is located between the anti-skid teeth 1911. The design of the weight-reducing hole 1912 can not only reduce the weight of the rear pedal 191, but also enable the sand or mud splashed onto the rear pedal 191 during the driving of the all-terrain vehicle 100 to be quickly discharged from the weight-reducing hole 1912, thereby avoiding the accumulation of sand and mud on the rear pedal 191. It is understandable that since mud and sand accumulation can easily cause the rear foot pedal 191 to become slippery, which is not conducive to the driver stepping on the rear foot pedal 191, in the present application, the anti-slip teeth 1911 are used to reduce the contact between the driver's feet and the mud and sand, and the mud and sand are quickly discharged through the weight reduction holes 1912, thereby improving the stability of the driver when stepping on the rear foot pedal 191, thereby improving the driver's driving safety.

[0057] like Figure 7 and Figure 8 As shown, the frame 11 includes a main frame 111 and a protective bracket 112 located in front of the main frame 111. The protective bracket 112 is fixedly connected to the main frame 111. The protective bracket 112 is mainly used to withstand impact loads. That is, when the all-terrain vehicle 100 has a collision accident, the protective bracket 112 absorbs the impact through its own deformation, thereby reducing the impact load transmitted to the driver, and preventing the all-terrain vehicle 100 from causing harm to the driver due to the collision accident. The protective bracket 112 includes an upper protective frame 1121. The upper protective frame 1121 is at least partially located above the front cover 121 and is fixedly connected to the main frame 111. The frame 11 also includes a heat dissipation bracket 113, referring to Fig. 9 As shown, the radiator 151 is mounted on the heat dissipation bracket 113, and the heat dissipation bracket 113 is at least partially located on the upper protective frame 1121 and connected to the upper protective frame 1121. The upper protective frame 1121 is at least partially arranged around the heat dissipation bracket 113. Along the width direction of the all-terrain vehicle 100, the upper protective frame 1121 is at least partially located on both sides of the heat dissipation bracket 113. The upper protective frame 1121 is mainly used to install the heat dissipation bracket 113 and protect the radiator 151 to prevent the radiator 151 from being damaged when the all-terrain vehicle 100 collides. Fig. 9As shown, as an alternative embodiment, one end of the heat dissipation bracket 113 is rotatably connected to the upper protective frame 1121, and the other end of the heat dissipation bracket 113 can be fixed and changed in relative position with respect to the upper protective frame 1121. Specifically, the heat dissipation bracket 113 and the upper protective frame 1121 are rotatably connected by a rotating shaft. The rotating shaft is located at the front end of the heat dissipation bracket 113 and extends along the width direction of the all-terrain vehicle 100 and sequentially passes through the upper protective frame 1121 and the heat dissipation bracket 113, so that the heat dissipation bracket 113 can rotate relative to the upper protective frame 1121 through the rotating shaft, thereby driving the radiator 151 to rotate. As Figure 8 shown, the all-terrain vehicle 100 further includes an electrical component 21. The electrical component 21 includes components such as a vehicle controller and a fuse box. In this application, the vehicle controller and the fuse box are both located at the front part of the all-terrain vehicle 100 and fixedly connected to the main frame 111, and the vehicle controller and the fuse box are located in front of the steering handle 161 and below the front head cover 121. The vehicle controller in this application refers to an ECU controller (ECU, Electronic Control Unit). Among them, in order to facilitate the maintenance when the vehicle controller and the fuse box fail, a maintenance opening 1211 is provided on the front head cover 121. The vehicle controller and the fuse box are located below the maintenance opening 1211, and the heat dissipation component 15 covers above the maintenance opening 1211, that is, when observing along the height direction of the all-terrain vehicle 100, the electrical component 21, the maintenance opening 1211 and the heat dissipation component 15 at least partially overlap. Further, when the all-terrain vehicle 100 needs to travel on muddy roads or wading roads for a long time, it is necessary to regularly maintain the heat dissipation component 15 to avoid damage caused by the overheating of the engine 141 due to the abnormal operation of the heat dissipation component 15. In this application, the heat dissipation bracket 113 includes a fixed state and an adjustment state. When the heat dissipation bracket 113 is in the fixed state, the heat dissipation bracket 113 is relatively fixed to the upper protective frame 1121, that is, the heat dissipation bracket 113 and the upper protective frame 1121 are in a relatively static state, and the rotation between the heat dissipation bracket 113 and the upper protective frame 1121 is restricted. When the heat dissipation bracket 113 is in the adjustment state, the heat dissipation bracket 113 can rotate relative to the upper protective frame 1121 around the rotating shaft, thereby driving the radiator 151 to rotate. Adjustment state

[0058] As Fig. 9As shown, specifically, the heat dissipation bracket 113 includes a rotating end 1131 and a fixed end 1132 distributed along the height direction of the all-terrain vehicle 100, the fixed end 1132 is at least partially located above the rotating end 1131, the rotating end 1131 is rotatably connected to the upper protective frame 1121, and the fixed end 1132 is detachably connected to the upper protective frame 1121, so that the radiator 151 can rotate relative to the upper protective frame 1121 along with the heat dissipation bracket 113 through the relative rotation of the rotating end 1131 and the upper protective frame 1121, thereby realizing the adjustment function of the radiator 151. Through the above arrangement, the heat dissipation component 15 is arranged on the front cover 121, and while the wading height of the all-terrain vehicle 100 is improved, the electrical component 21 of the all-terrain vehicle 100 can also be inspected and repaired through the rotation of the heat dissipation bracket 113, thereby improving the maintenance performance of the all-terrain vehicle 100. It can be understood that after the all-terrain vehicle 100 passes through a muddy section or a wading section, the heat dissipation bracket 113 is switched to the adjustment state, and the front and rear parts of the radiator 151 can also be cleaned and maintained to avoid the rear half of the radiator 151 not being cleaned for a long time during the use of the all-terrain vehicle 100, resulting in blockage of the radiator 151 and making the radiator 151 unable to work normally, thereby improving the maintainability and service life of the radiator 151.

[0059] like Fig. 9 and Fig.10 As shown, further, the upper protective frame 1121 includes a connecting portion 1121a and a mounting hole 1121b. When the heat dissipation bracket 113 is in a fixed state, the connecting portion 1121a is located below the mounting hole 1121b, and the connecting portion 1121a is also at least partially located in front of the mounting hole 1121b. The rotating end 1131 is rotatably connected to the connecting portion 1121a, wherein the rotating end 1131 and the connecting portion 1121a overlap along the width direction of the all-terrain vehicle 100, and the rotating axis passes through the rotating end 1131 and the connecting portion 1121a in sequence, so that the rotating end 1131 can rotate relative to the connecting portion 1121a through the rotating axis; the upper protective bracket 112 also includes a fixing member 1121c. The fixing member 1121c passes through the mounting hole 1121b and is fixedly connected to the fixed end 1132. When the heat dissipation bracket 113 is in a fixed state, the fixing member 1121c is fixedly connected to the fixed end 1132 to limit the rotation of the heat dissipation bracket 113.

[0060] As an optional embodiment, the fixing end 1132 includes a fixing hole 1132a. When the mounting hole 1121b is connected to the connecting portion 1121a, the fixing hole 1132a and the mounting hole 1121b overlap in the width direction of the all-terrain vehicle 100, and the fixing member 1121c passes through the mounting hole 1121b and is connected to the fixing hole 1132a, so that the heat dissipation bracket 113 and the upper protective frame 1121 are relatively fixed, and the radiator 151 is fixed. Through the above arrangement, the radiator 151 can be The relative rotation of the rotating end 1131 and the connecting portion 1121a on the heat dissipation bracket 113 realizes the adjustment function of the radiator 151, and the fixing hole 1132a and the mounting hole 1121b can be relatively fixed by the fixing member 1121c, thereby avoiding the safety hazard caused by the rotation of the rotating end 1131 relative to the connecting portion 1121a during the driving of the all-terrain vehicle 100, thereby improving the connection stability of the heat dissipation bracket 113 and improving the driving safety of the all-terrain vehicle 100.

[0061] It should be noted that, specifically, two connecting parts 1121a and two rotating ends 1131 are provided, and the two connecting parts 1121a and the two rotating ends 1131 are distributed along the width direction of the all-terrain vehicle 100, and the rotating shaft passes through the two connecting parts 1121a and the two rotating ends 1131; specifically, the two connecting parts 1121a are basically located on the left and right sides of the upper protective frame 1121, and the two rotating ends 1131 are basically located on both sides of the heat dissipation bracket 113. This arrangement makes the rotation connection between the heat dissipation bracket 113 and the radiator 151 more stable. Optionally, two fixed ends 1132 and two fixing members 1121c are also provided, and the two fixed ends 1132 and the two fixing members 1121c are distributed along the width direction of the all-terrain vehicle 100, and the two fixed ends 1132 are basically located on both sides of the heat dissipation bracket 113, and the two fixing members 1121c are basically located on both sides of the upper protective frame 1121. Through the above arrangement, when the radiator 151 is in a fixed state, the heat dissipation bracket 113 is connected to the upper protective frame 1121 through four mounting points, which can not only improve the connection stability between the heat dissipation bracket 113 and the upper protective frame 1121, but also improve the rotation stability of the heat dissipation bracket 113 relative to the upper protective frame 1121, making the rotation of the heat dissipation bracket 113 more stable.

[0062] like Fig.10As shown, when the heat dissipation bracket 113 is in the adjustment state, the heat dissipation bracket 113 is only rotatably connected to the connection part 1121a through the rotating end 1131, and is not relatively fixed to the upper protective frame 1121. At this time, the heat dissipation bracket 113 can drive the radiator 151 to rotate by artificially applying external force, and a second preset plane 103 is defined. The radiator 151 basically extends along the second preset plane 103, and an angle α is formed between the second preset plane 103 and the horizontal plane 101. In this application, the angle α between the second preset plane 103 and the horizontal plane 101 can directly affect the air intake of the radiator 151. Specifically, during the rotation of the heat dissipation bracket 113 in the adjustment state, the heat dissipation bracket 113 has a maximum adjustment state. The angle α when the heat dissipation bracket 113 is in the maximum adjustment state is defined as the maximum adjustment angle. The range of the angle α is 90° to 110°. As a specific implementation method, the maximum adjustment angle is 100°. Furthermore, the heat dissipation bracket 113 further includes a stopper 1133, which is arranged in front of the rotating end 1131, so that during the rotation of the heat dissipation bracket 113, the stopper 1133 can rotate with the heat dissipation bracket 113 until it abuts against the connecting portion 1121a, thereby preventing the heat dissipation bracket 113 from rotating excessively. When the stopper 1133 abuts against the connecting portion 1121a, the heat dissipation bracket 113 is in a maximum adjustment state. At this time, when observing along the height direction of the all-terrain vehicle 100, at least part of the electrical component 21 can be observed through the inspection port 1211. Through the above arrangement, it is possible to avoid the maximum adjustment angle being set too small, which is not conducive to maintenance personnel maintaining the electrical component 21 or the radiator 151, and it is also possible to avoid the maximum adjustment angle being set too large, which causes the pipeline between the radiator 151 and the engine 141 to be too long, which is not conducive to the layout of the pipeline.

[0063] It can be understood that when the heat dissipation bracket 113 is switched from a fixed state to an adjustable state, the fixing piece 1121c is first removed to disconnect the fixed end 1132 from the upper protective frame 1121, and the rotating end 1131 is rotated relative to the connecting portion 1121a by applying external force, so that the heat dissipation bracket 113 rotates forward or backward with the connecting portion 1121a as the rotation center until the limit piece 1133 abuts against the connecting portion 1121a. At this time, the heat dissipation bracket 113 is in the maximum adjustment state, and the driver and maintenance personnel can inspect and repair the all-terrain vehicle 100.

[0064] When the heat dissipation bracket 113 is in the maximum adjustment state, the driver or maintenance personnel need to clean and maintain both sides of the radiator 151, and inspect the vehicle controller and the fuse box through the inspection port 1211. At this time, the heat dissipation bracket 113 needs to be fixed in the maximum adjustment state. Specifically, the frame 11 also includes a support frame 114, which is arranged on the main frame 111. The support frame 114 is basically rod-shaped, and one end of the support frame 114 is rotatably connected to the main frame 111. The heat dissipation bracket 113 is provided with a supporting fixing portion 1134 that cooperates with the support frame 114. When the heat dissipation bracket 113 is in the maximum adjustment state, the support frame 114 is rotated and the end of the support frame 114 away from the rotation center is clamped with the supporting fixing portion 1134, so that the heat dissipation bracket 113 is fixed in the maximum adjustment state, that is, during the inspection process, it is ensured that the heat dissipation bracket 113 will not flip backwards, affecting the maintenance or causing damage to the heat dissipation bracket 113. At this time, when viewed along the width direction of the ATV 100, the heat dissipation bracket 113, the support frame 114 and the main frame 111 form a triangular structure, so that the heat dissipation bracket 113 can be stably in the adjustment state. When the ATV 100 is overhauled, the heat dissipation bracket 113 needs to be switched from the adjustment state to the fixed state. At this time, the support frame 114 needs to be stored first. Figure 8 As shown, the main frame 111 is also provided with a clamping portion 1111 for cooperating with the support frame 114. The support frame 114 is released from the clamping state with the support fixing portion 1134 and can be clamped with the clamping portion 1111 after rotation, so that the support frame 114 can be relatively fixed to prevent the support frame 114 from shaking during the driving of the all-terrain vehicle 100. When the support frame 114 is clamped with the clamping portion 1111, the support frame 114 basically extends along the width direction of the all-terrain vehicle 100. Through the above arrangement, the arrangement of the support frame 114 allows the heat dissipation bracket 113 to be stably in an adjusted state, and prevents the heat dissipation bracket 113 from flipping backwards under the action of its own gravity and hitting the maintenance personnel, thereby threatening the life safety of the maintenance personnel, thereby facilitating the maintenance personnel to maintain the all-terrain vehicle 100.

[0065] like Fig.11As shown, the protection bracket 112 also includes a lower protection frame 1122, the lower protection frame 1122 and the upper protection frame 1121 are distributed along the height direction of the all-terrain vehicle 100, and the upper protection frame 1121 and the lower protection frame 1122 are both fixedly connected to the main frame 111, the upper protection frame 1121 is also located above the lower protection frame 1122 and is detachably connected to the lower protection frame 1122 by bolt connection, and the lower protection frame 1122 is also at least partially located in front of the main frame 11. Since the lower protection frame 1122 is located at the front part of the all-terrain vehicle 100, the lower protection frame 1122 is the component that mainly bears the impact load. Through the above arrangement, the upper protection frame 1121 and the lower protection frame 1122 adopt a split design, so that the lower protection frame 1122 can reduce the impact load transmitted to the upper protection frame 1121 while receiving most of the impact, thereby avoiding damage to the radiator 151. In addition, when repairing the damaged upper protection frame 1121 or the lower protection frame 1122, the split design can also replace and repair the upper protection frame 1121 or the lower protection frame 1122 separately, thereby avoiding the need to remove the entire protection frame 112 for repair and replacement, thereby reducing the maintenance cost of the all-terrain vehicle 100. In addition, during the transportation of the all-terrain vehicle 100, the split design of the upper protection frame 1121 and the lower protection frame 1122 also allows the upper protection frame 1121 and the lower protection frame 1122 to be disassembled and transported separately, thereby reducing the difficulty of packaging the entire all-terrain vehicle 100 during transportation and improving the convenience of transportation of the all-terrain vehicle 100.

[0066] Furthermore, the lower protection frame 1122 includes a mounting portion 1122a, which at least partially overlaps with the upper protection frame when viewed along the height direction of the all-terrain vehicle. The upper protection frame 1121 is bolted to the mounting portion 1122a, so that a detachable connection is formed between the upper protection frame 1121 and the lower protection frame 1122. The vehicle body cover 12 also includes a protective plate 124 (see Figure 7 ), the protective plate 124 is fixedly connected to the lower protective frame 1122, and the protective plate 124 is at least partially located below and in front of the lower protective frame 1122. Since the all-terrain vehicle 100 often travels on gravel roads, the protective plate 124 can protect the electrical components 21 located at the front part of the all-terrain vehicle 100 to prevent the electrical components 21 from being damaged by sand and gravel splashing. Furthermore, the protective plate 124 can be made of metal, so as to improve the structural strength of the protective plate 124 and avoid damage to the protective plate 124 itself. The upper protective frame 1121 includes a connecting hole 1121d, and the connecting hole 1121d is located at the rear end of the upper protective frame 1121. The upper protective frame 1121d is fixedly connected to the main frame 111 through the connecting hole 1121d, thereby realizing the fixed connection between the upper protective frame 1121 and the main frame 111.

[0067] Reference Fig.12and Fig.13 On the basis that the heat dissipation bracket 113 can be flipped, the heat dissipation bracket 113 also has the function of angle adjustment, that is, the heat dissipation bracket 113 has multiple angles and positions connected to the upper protective frame 1121 during the flipping process, so that the heat dissipation bracket 113 can be switched to a fixed state at different angles. Specifically, when the heat dissipation bracket 113 is in a fixed state, the heat dissipation bracket 113 and the upper protective frame 1121 include a first limit position and a second limit position. When the heat dissipation bracket 113 is in the first limit position, the angle α1 between the second preset plane 103 and the horizontal plane 101 is the first limit fixed angle. When the heat dissipation bracket is in the second limit position, the angle α2 between the second preset plane 103 and the horizontal plane 101 is the second limit fixed angle. The difference between the first limit fixed angle and the second limit fixed angle is 12° to 36°. The first limit fixed angle is 30° to 42°, and the second limit fixed angle is 54° to 66°. In this embodiment, the first limit fixed angle is 36°, the second limit fixed angle is 60°, and the difference between the first limit fixed angle and the second limit fixed angle is 24°. Through the above settings, the heat dissipation bracket 113 can be adjusted between the first limit fixed angle and the second limit fixed angle to change the angle between the second preset plane 103 and the horizontal plane 101, thereby changing the air intake of the radiator 151, and adjusting the angle of the heat dissipation bracket 113 according to the actual needs of the driver, thereby improving the driving experience of the driver. Specifically, the angle adjustment structure of the heat dissipation bracket 113 is described in detail below through an embodiment.

[0068] like Fig.12 and Fig.13 As shown, as a first embodiment, it includes a frame 23 and a heat dissipation assembly 15 that are substantially the same as those described above. The heat dissipation assembly 15 includes a radiator 151, and the frame 23 includes a heat dissipation bracket 231 and an upper protective frame 232. The heat dissipation bracket 231 includes a fixed end 2312 and a rotating end 2311. The upper protective frame 232 includes a connecting portion 2321, and the connecting portion 2321 is rotatably connected to the rotating end 2311. Specifically, the upper protective frame 232 is provided with mounting holes 2322 that penetrate the upper protective frame 232 along the width direction of the all-terrain vehicle 100. The mounting holes 2322 include a first mounting hole 2322a and a second mounting hole 2322b. The first mounting hole 2322a and the second mounting hole 2322b are distributed along the height direction of the all-terrain vehicle 100. The fixed end 2312 is provided with a fixing hole 2312a (refer to Fig.101132a), a fixing piece 2323 is also provided on the upper protective frame 232. When the fixed end 2312 of the heat dissipation bracket 231 and the upper protective frame 232 are in a fixed state, and the rotating end 2311 of the heat dissipation bracket 231 rotates relative to the connecting portion 2321 of the upper protective frame 232, the fixing hole 2312a can be rotated to coincide with the first mounting hole 2322a or the second mounting hole 2322b along the width direction of the all-terrain vehicle 100. When the fixing hole 2312a coincides with the first mounting hole 2322a or the fixing hole 2312a coincides with the second mounting hole 2322b, the fixing piece 2323 passes through the first mounting hole 2322a or the second mounting hole 2322b and is fixedly connected to the fixing hole 2312a. At this time, the heat dissipation bracket 231 is fixedly connected to the upper protective frame 1121. It should be noted that when the fixing member 2323 of the heat dissipation bracket 231 is fixedly connected to the fixing hole 2312a through the first mounting hole 2322a, the heat dissipation bracket 231 is in the first extreme position, and when the fixing member 2323 of the heat dissipation bracket 231 is fixedly connected to the fixing hole 2312a through the second mounting hole 2322b, the heat dissipation bracket 231 is in the second extreme position.

[0069] like Fig.12 and Fig.13As shown, in this embodiment, the heat dissipation bracket 231 can adjust the angle of the radiator 151 by being fixedly connected to the first mounting hole 2322a and the second mounting hole 2322b respectively. Since the first mounting hole 2322a and the second mounting hole 2322b are at different heights, the size of the angle α formed by the second preset plane 103 and the horizontal plane 101 is also different. When the fixing member 2323 is fixedly connected to the fixing hole 2312a through the first mounting hole 2322a, the angle α1 between the second preset plane 103 and the horizontal plane 101 is 30° to 42°. In this embodiment, the angle α1 between the second preset plane 103 and the horizontal plane 101 is 36°, and the heat dissipation bracket 231 is at the first limit fixed angle. When the fixing member 2323 is fixedly connected to the fixing hole 2312a through the second mounting hole 2322b, the angle α2 between the second preset plane 103 and the horizontal plane 101 is 54° to 66°. In the present embodiment, the angle α2 between the second preset plane 103 and the horizontal plane 101 is 60°, and the heat dissipation bracket 231 is at the second limit fixed angle. It should be noted that the all-terrain vehicle 100 includes two different speed modes, namely, a low speed mode and a high speed mode. When the all-terrain vehicle 100 is in the high speed mode, the engine needs to output more power, and the engine dissipates more heat during operation. Therefore, the heat dissipation component 15 needs a larger air intake to reduce the temperature of the engine. In the present embodiment, when the all-terrain vehicle 100 is in the high speed mode, the heat dissipation bracket 231 is in the second limit position, and when the all-terrain vehicle 100 is in the low speed mode, the heat dissipation bracket 231 is in the first limit position. It can be understood that when the heat dissipation bracket 231 is in the second extreme position, the air intake volume of the radiator 151 is greater than the air intake volume of the radiator 151 when the heat dissipation bracket 231 is in the first extreme position, so that when the all-terrain vehicle 100 is in high-speed mode, the radiator 151 can improve the heat dissipation effect of the radiator 151 through a larger air intake volume, so that the engine temperature is within a suitable temperature range.

[0070] like Fig.14As shown, specifically, a transverse plane 104 perpendicular to the length direction of the all-terrain vehicle 100 is defined. When the angle α3 between the second preset plane 103 and the horizontal plane 101 is 90°, the radiator 151 is in an upright state. At this time, the projection surface of the radiator 151 along the length direction of the all-terrain vehicle 100 on the transverse plane 104 is defined as the heat dissipation projection surface. The area of ​​the heat dissipation projection surface is the area of ​​the radiator 151, and is also the maximum air inlet area of ​​the radiator 151. When the heat dissipation bracket 231 is in the first extreme position, the projection surface of the radiator 151 on the transverse plane 104 along the length direction of the all-terrain vehicle 100 is defined as a first projection surface, and the area of ​​the first projection surface is the air inlet area of ​​the radiator 151 when the heat dissipation bracket 231 is in the first extreme position; when the heat dissipation bracket 231 is in the second extreme position, the projection surface of the radiator 151 on the transverse plane 104 along the length direction of the all-terrain vehicle 100 is defined as a second projection surface, and the area of ​​the second projection surface is the air inlet area of ​​the radiator 151 when the heat dissipation bracket 231 is in the second extreme position. The area of ​​the second projection surface is greater than that of the first projection surface, indicating that when the heat dissipation bracket 231 is in the second extreme position, the radiator 151 can obtain a larger air inlet volume, thereby improving the heat dissipation effect of the radiator 151. Through the above-mentioned setting, the setting of the angle α can not only prevent the angle of the heat dissipation bracket 231 from being too large when it is in the first extreme position or the second extreme position, causing the radiator 151 to block the driver's line of sight, but also prevent the angle α from being too small, causing the radiator 151 to fail to obtain the air intake volume matching the current speed mode, resulting in poor working efficiency of the radiator 151. Therefore, while meeting the working requirements of the radiator 151, it can also prevent the position of the radiator 151 from being too high to affect the driver's observation of the road conditions, thereby improving the driving safety of the all-terrain vehicle 100.

[0071] like Fig.15 As shown, as a second embodiment, it includes a frame 33 and a heat dissipation assembly 15 that are basically the same as the first embodiment, the heat dissipation assembly 15 includes a radiator 151, and the frame 33 includes a heat dissipation bracket 331 and an upper protective frame 332. The parts that are different from the first embodiment are introduced below.

[0072] like Fig.15As shown, the heat dissipation bracket 331 includes a rotating end 3311 and a fixed end 3312 distributed along the height direction of the all-terrain vehicle 100, and the upper protective frame 332 includes a connecting portion 3321, the rotating end 3311 is rotatably connected to the connecting portion 3321, and the fixed end 3312 is detachably connected to the upper protective frame 332. Specifically, the fixed end 3312 further includes an adjustment slot 3312a, and the upper protective frame 332 further includes a fixing member 3322 and a mounting hole 3323. The fixing member 3322 at least partially passes through the adjustment slot 3312a and is fixedly connected to the mounting hole 3323, so that the fixed end 3312 is fixedly connected to the upper protective frame 332. It can be understood that when the heat dissipation bracket 331 rotates relative to the upper protective frame 332, the adjustment slot 3312a also rotates synchronously with the heat dissipation bracket 331. When the adjustment slot 3312a rotates to any position within the preset rotation range, the mounting hole 3323 is observed along the extension direction of the mounting hole 3323. At least partially overlap with the adjustment slot 3312a, that is, the adjustment slot 3312a rotates to any position within the preset rotation range, and the fixing member 3322 can be passed through the adjustment slot 3312a and fixedly connected to the mounting hole 3323. It can be understood that in this embodiment, the fixing member 3322 is set as a fastener such as a bolt. In this embodiment, when the fixing member 3322 moves to the two ends of the adjustment slot 3312a, the heat dissipation bracket 331 is respectively in the first extreme position and the second extreme position. Specifically, when the fixing member 3322 is located at the lower end of the adjustment slot 3312a, the heat dissipation bracket 331 is in the first extreme position, and when the fixing member is located at the upper end of the adjustment slot 3312a, the heat dissipation bracket 331 is in the second extreme position. The "preset rotation range" mentioned above is the rotation range of the heat dissipation bracket 331 when it rotates between the first extreme position and the second extreme position.

[0073] In this embodiment, the adjustment groove 3312a can be set to an arc shape, defining a longitudinal plane 105 perpendicular to the width direction of the all-terrain vehicle 100, and the projection of the rotation center of the heat dissipation bracket 331 along the width direction of the all-terrain vehicle 100 on the longitudinal plane 105 is defined as the rotation center projection, and the center of the projection of the adjustment groove 3312a along the width direction of the all-terrain vehicle 100 on the longitudinal plane 105 coincides with the rotation center projection, that is, when observed along the width direction of the all-terrain vehicle 100, the arc shape of the adjustment groove 3312a has the axis of the rotation center of the heat dissipation bracket 331 as the center. Furthermore, a plurality of limiting portions 3312b are formed in the adjusting groove 3312a, and the limiting portions 3312b are evenly distributed in the adjusting groove 3312a, and the limiting portions 3312b divide the adjusting groove 3312a into a plurality of areas, each area allows the fixing member 3322 to pass through the adjusting groove 3312a, and when the fixing member 3322 is located in the area, the limiting portion 3312b abuts against the fixing member 3322, so that the position of the fixing member 3322 in the adjusting groove 3312a is relatively fixed, and when the fixing member 3322 passes through the adjusting groove 3312a, the fixing member 3322 is located between two adjacent limiting portions 3312b, or the fixing member 3322 is located between the limiting portion 3312b and the inner wall of the adjusting groove 3312a. Specifically, the limiting portion 3312b is configured as a unilateral toothed structure, so that the heat dissipation bracket 331 and the upper protective frame 332 can be relatively fixed without affecting the rotation of the heat dissipation bracket 331. Through the above configuration, the limiting portion 3312b can not only provide a positioning function for the installation of the fixing member 3322, but also improve the connection stability between the fixing member 3322 and the mounting hole 3323, thereby preventing the heat dissipation bracket 113 from shaking due to the loose connection between the heat dissipation bracket 331 and the upper protective frame 332 during the driving of the all-terrain vehicle 100. In addition, the limiting portion 3312b can also form different adjustment gears, so that the driver can adjust the position of the heat dissipation bracket 113.

[0074] It can be understood that when the heat dissipation bracket 113 needs to be adjusted, the fixing piece 3322 is first removed from the adjustment slot 3312a. At this time, the heat dissipation bracket 331 can rotate relative to the upper protective frame 332 around the rotation center, that is, the radiator 151 can rotate relative to the upper protective frame 332, and the adjustment slot 3312a can also change its position relative to the upper protective frame 332; while rotating the heat dissipation bracket 331 to a suitable position, ensure that the mounting hole 3323 and the adjustment slot 3312a are in an overlapping state along the width direction of the all-terrain vehicle 100. At this time, the fixing piece 3322 is passed through the adjustment slot 3312a and is fixedly connected with the mounting hole 3323, and the position adjustment of the radiator 151 is completed.

[0075] Further, the heat dissipation bracket 113 can adjust the angle between the radiator 151 and the horizontal plane by moving the fixing member 3322 in the adjustment slot 3312a. The fixing member means that when the heat dissipation bracket 331 is in the first limit position, the second preset plane 103 and the horizontal plane 101 are at the first limit fixed angle, and the angle α1 between the second preset plane 103 and the horizontal plane 101 is 30° to 42°. In this embodiment, the angle α1 between the second preset plane 103 and the horizontal plane 101 is 36°. When the heat dissipation bracket 331 is in the second limit position, the second preset plane 103 and the horizontal plane 101 are at the second limit fixed angle, and the angle α2 between the second preset plane 103 and the horizontal plane 101 is 54° to 66°. In this embodiment, the angle α2 between the second preset plane 103 and the horizontal plane 101 is 60°. It can be understood that the angle difference between the first limit fixed angle and the second limit fixed angle is the "preset rotation range" described above. Through the above-mentioned setting, the setting of the angle α can prevent the adjustment angle of the heat dissipation bracket 113 from being too large, causing the radiator 151 to block the driver's line of sight, and can also prevent the angle α from being too small, causing the radiator 151 to be unable to obtain the air intake volume matching the current speed mode, resulting in poor working efficiency of the radiator 151. While meeting the working requirements of the radiator 151, it can also prevent the position of the radiator 151 from being too high to affect the driver's observation of the road conditions, thereby improving the driving safety of the all-terrain vehicle 100.

[0076] Specifically, refer to Fig.14 , define a transverse plane 104 perpendicular to the length direction of the all-terrain vehicle 100, define the projection surface of the radiator 151 on the transverse plane 104 along the length direction of the all-terrain vehicle 100 as the heat dissipation projection surface, assume that the angle α3 between the second preset plane 103 and the horizontal is 90°, and the radiator 151 is in an upright state at this time, and the area of ​​the heat dissipation projection surface is the area of ​​the radiator 151, and is also the maximum air inlet area of ​​the radiator 151. When the heat dissipation bracket 331 is in the first extreme position, the area of ​​the heat dissipation projection surface is greater than the area of ​​the heat dissipation projection surface of the second projection surface when the heat dissipation bracket 331 is in the second extreme position, that is, the area of ​​the heat dissipation projection surface increases with the increase of the angle adjustment between the second preset plane 103 and the horizontal plane 101, so that with the adjustment of the heat dissipation bracket 331, the radiator 151 can obtain a larger air inlet volume, thereby improving the heat dissipation effect of the radiator 151.

[0077] It should be noted that, for the radiator 151 in the second embodiment, the angle α between the second preset plane 103 and the horizontal plane 101 is at least partially the same as the angle between the second preset plane 103 and the horizontal plane 101 in the first embodiment. In the present application, the all-terrain vehicle 100 includes two different speed modes, namely, a low speed mode and a high speed mode. The air intake required to satisfy the heat dissipation of the radiator 151 in the two modes is different. Therefore, at least one limiting portion 3312b is provided so that the adjustment slot 3312a can be divided into at least two areas, so that the radiator 151 can be adjusted to at least two different positions to achieve at least two angles of the radiator 151. The number of limiting portions 3312b can also be set to multiple, so that while satisfying the air intake requirements of the radiator 151, the driver can also adjust the angle of the radiator 151 multiple times according to actual needs during driving.

[0078] like Fig.16 As shown, as a third embodiment, it includes a frame 43 and a heat dissipation assembly 15 that are substantially the same as those of the second embodiment. The heat dissipation assembly 15 includes a radiator 151. The parts that are different from those of the second embodiment are described below.

[0079] like Fig.16 As shown, the frame 43 includes a heat dissipation bracket 431 and an upper protective frame 432. The heat dissipation bracket 431 includes a rotating end 4311 and a fixed end 4312. The upper protective frame 432 includes a connecting portion 4321, and the connecting portion 4321 is rotatably connected to the rotating end 4311. The fixed end 4312 is provided with an adjustment slot 4312a. The upper protective frame 432 also includes a fixing member 4322 and a mounting hole 4323. The fixing member 4322 at least partially passes through the adjustment slot 4312a and is fixedly connected to the mounting hole 4323. Specifically, a connection mode of gear and rack is arranged between the fixing member 4322 and the adjusting groove 4312a, that is, the outer periphery of the fixing member 4322 is arranged as a gear structure, and the inner wall of the adjusting groove 4312a is arranged as an arc-shaped rack structure. When the fixing member 4322 passes through the adjusting groove 4312a and is fixedly connected to the mounting hole 4323, the gear on the fixing member 4322 can engage with the tooth groove in the adjusting groove 4312a. Through this installation mode, when the fixing member 4322 is rotated, the adjusting groove 4312a can rotate with the rotation center of the heat dissipation bracket 431 as the center of the circle.

[0080] Furthermore, the fixing member 4322 is provided with an adjusting knob 4322a and a fixing button 4322b. The adjusting knob 4322a is used to control the rotation of the gear structure outside the fixing member 4322. When the adjusting knob 4322a is rotated, the gear structure rotates accordingly, thereby driving the adjusting slot 4312a to rotate to achieve the angle adjustment of the heat dissipation bracket 113; the fixing button 4322b is used to achieve the fixed connection between the heat dissipation bracket 431 and the upper protective frame 432. The fixing button 4322b is in a protruding state by default. The fixing button 4322b can be in a pressed state by an odd number of presses or in a pressed state by an even number of presses. When pressed, it is in the convex state again. When the fixed button 4322b is in the convex state, the adjusting knob 4322a cannot be rotated, and the gear structure cannot be rotated, that is, the adjustment knob 4322a cannot be used to rotate the gear structure to control the rotation of the adjustment slot 4312a. When the fixed button 4322b is in the pressed state, the gear structure can rotate relative to the rack structure to drive the adjustment slot 4312a to rotate. At this time, the gear structure can be rotated by adjusting the knob 4322a to drive the adjustment slot 4312a to rotate, thereby realizing the adjustment of the position of the heat dissipation bracket 431 and then realizing the angle adjustment. It can be understood that in this way, it is only necessary to press the fixing button 4322b to put the fixing button 4322b in a pressed state to make the heat dissipation bracket 431 enter the adjustment state, and through the adjusting knob 4322a, the adjustment slot 4312a rotates with the heat dissipation bracket 431. When the heat dissipation bracket 431 completes the adjustment of the relative position, it is only necessary to press the fixing button 4322b again, and the heat dissipation bracket 431 is in a fixed state, so that the angle adjustment of the heat dissipation component 15 can be completed. This setting method makes the adjustment method of the heat dissipation component 15 simpler and the adjustment accuracy is higher.

[0081] Reference Fig.14In this embodiment, when the fixing member 4322 moves to the two ends of the adjusting groove 4312a in the adjusting groove 4312a, the heat dissipation bracket 431 is respectively in the first limit position and the second limit position. Specifically, when the fixing member 4322 is located at the lower end of the adjusting groove 4312a, the heat dissipation bracket 431 is in the first limit position, and when the fixing member is located at the upper end of the adjusting groove 4312a, the heat dissipation bracket 431 is in the second limit position. Further, when the heat dissipation bracket 431 is in the first limit position, the angle between the second preset plane 103 and the horizontal plane 101 is the first limit fixed angle, and the first limit fixed angle is 30° to 42°; when the heat dissipation bracket 431 is in the second limit position, the angle between the second preset plane 103 and the horizontal plane 101 is the second limit fixed angle, and the second limit fixed angle is 54° to 66°. The difference between the first limit fixed angle and the second limit fixed angle is the angle adjustment range of the heat dissipation bracket. In this embodiment, the first limit fixed angle is 36°, and the second limit fixed angle is 60°. Through the above arrangement, the fixing member 4322 and the adjustment slot 4312a are steplessly adjusted by means of a gear rack, and the driver can select any adjustment angle within the angle adjustment range of the heat dissipation bracket 431, thereby meeting the driver's personalized adjustment needs, so that the driver can adjust the adjustment angle of the heat dissipation bracket 431 in real time according to the actual needs during driving, thereby improving the convenience of adjusting the angle of the heat dissipation bracket 431. Specifically, a transverse plane 104 perpendicular to the length direction of the all-terrain vehicle 100 is defined, and the projection surface of the radiator 151 on the transverse plane 104 along the length direction of the all-terrain vehicle 100 is defined as the heat dissipation projection surface. Assuming that the angle α between the second preset plane 103 and the horizontal is 90°, the radiator 151 is in an upright state at this time, and the area of ​​the heat dissipation projection surface is the area of ​​the radiator 151, which is also the maximum air inlet area of ​​the radiator 151. When the heat dissipation bracket 431 is in the first extreme position, that is, the second preset plane 103 and the horizontal plane 101 are at the first extreme fixed angle, the projection surface of the radiator 151 on the transverse plane 104 along the length direction of the all-terrain vehicle 100 is defined as the first projection surface; when the heat dissipation bracket 431 is in the second extreme position in the adjustment state, that is, the second preset plane 103 and the horizontal plane 101 are at the second extreme fixed angle, the projection surface of the radiator 151 on the transverse plane 104 along the length direction of the all-terrain vehicle 100 is defined as the second projection surface, and the ratio of the area of ​​the second projection surface to the area of ​​the first projection surface is 1.2 to 1.7. Therefore, as the heat dissipation bracket 431 is adjusted, the angle between the second preset plane 103 and the horizontal plane 101 gradually increases, so that the radiator 151 can obtain a larger air intake, thereby improving the heat dissipation effect of the radiator 151.

[0082] like Fig.17As shown, as an optional implementation, since the upper protective frame 1121 is connected to the heat dissipation bracket 113, the upper protective frame 1121 is also detachably connected to the lower protective frame 1122, so that the rotation function of the radiator 151 can be realized by fixing the heat dissipation bracket 113 to the upper protective frame 1121 and rotatably connecting the upper protective frame 1121 to the lower protective frame 1122. Specifically, the lower protective frame 1122 includes a rotating portion 1122b, which is located at the upper end of the lower protective frame 1122. The upper protective frame 1121 also includes a rotating connection portion 1121e. When viewed along the width direction of the all-terrain vehicle 100, the rotating connection portion 1121e and the rotating portion 1122b overlap. The lower protective frame 1122 also includes a rotating shaft 1122c, which extends along the width direction of the all-terrain vehicle 100. The rotating shaft 1122c passes through the rotating connection portion 1121e and the rotating portion 1122b, so that the rotating connection portion 1121e can rotate relative to the rotating portion 1122b, so that the upper protective frame 1121 and the lower protective frame 1122 can be rotatably connected, that is, the upper protective frame 1121 can be flipped forward along the length direction of the all-terrain vehicle 100, and since the heat dissipation bracket 113 is fixedly connected to the upper protective frame 1121, the flipping function of the radiator 151 can be realized. In this embodiment, the upper protective frame 1121 includes a fixed state and an adjustable state. When the upper protective frame 1121 is in the fixed state, the upper protective frame 1121 is fixedly connected to the main frame 111. When the upper protective frame 1121 is in the adjustable state, the upper protective frame 1121 and the main frame 111 are released from the fixed connection, and the upper protective frame 1121 and the lower protective frame 1122 rotate relative to each other. Through the above-mentioned arrangement, when the radiator 151 realizes the rotation function through the upper protective frame 1121, since the upper protective frame 1121 is at least partially located on both sides of the heat dissipation bracket 113 along the width direction of the all-terrain vehicle 100, the upper protective frame 1121 is in an adjustment state. When the driver or maintenance personnel maintain the electrical components 21 and the radiator 151, the upper protective frame 1121 will interfere with the operation of the maintenance personnel, thereby causing inconvenience to the maintenance personnel during the maintenance process. In this embodiment, the rotation function of the radiator 151 is realized by the upper protective frame 1121, so that when the radiator 151 needs to be rotated, the upper protective frame 1121 can drive the heat dissipation bracket 113 to rotate together, thereby avoiding the upper protective frame 1121 from interfering with the maintenance of the driver or maintenance personnel, thereby improving the maintenance performance of the all-terrain vehicle 100.

[0083] In this embodiment, the upper protective frame 1121 may be provided with an abutment member 1121f, which is located at the lower end of the upper protective frame 1121, and the abutment member 1121f is also at least partially located in front of the rotating connection portion 1121e, so that the abutment member 1121f rotates with the rotation of the upper protective frame 1121 until the abutment member 1121f abuts against the lower protective frame 1122, at which time the upper protective frame 1121 rotates to the maximum adjustment state. A second preset plane 103 is defined, and the radiator 151 basically extends along the second preset plane 103. An angle α is formed between the second preset plane 103 and the horizontal plane 101. When the upper protective frame 1121 is in the maximum adjustment state, the angle α is in the maximum adjustment angle. At this time, the range of the angle α is 90° to 110°. In this embodiment, the angle α is 100°. Through the above arrangement, the arrangement of the abutment 1121f can prevent the upper protective frame 1121 from turning over too much, thereby preventing the center of gravity of the radiator 151 and the upper protective frame 1121 from moving forward and causing the rotating portion 1122b and the rotating connection portion 1121e to bear too much pressure, thereby preventing the rotating shaft 1122c from breaking, and improving the connection stability of the upper protective frame 1121 and the lower protective frame 1122. In addition, the abutment 1121f can also prevent the upper protective frame 1121 from turning over too much, resulting in the pipeline between the heat dissipation assembly 15 and the engine 141 being too long, which is not conducive to the layout of the pipeline.

[0084] It can be understood that in this way, when the upper protective frame 1121 is switched from a fixed state to an adjustable state, the fasteners at the connecting hole 1121d are first removed to release the fixed connection between the upper protective frame 1121 and the main frame 111, and then the upper protective frame 1121 is rotated forward along the length direction of the all-terrain vehicle 100 until the abutment 1121f abuts against the lower protective frame 1122. At this time, the heat dissipation assembly 15 is in the maximum adjustment state. After the inspection is completed, the upper protective frame 1121 is rotated backward along the length direction of the all-terrain vehicle 100 until the upper protective frame 1121 returns to its initial position, and then the fasteners are fixed in the connecting hole 1121d to complete a flip of the heat dissipation assembly 15.

[0085] like Fig.18As shown, the heat dissipation assembly 15 also includes a heat dissipation shield 152 and an air inlet grille 153 located on the heat dissipation shield 152. The heat dissipation shield 152 is fixedly connected to the heat dissipation bracket 113. When the heat dissipation bracket 113 rotates, the heat dissipation shield 152 and the air inlet grille 153 also rotate together. The heat dissipation shield 152 is used to protect the radiator 151 to prevent the radiator 151 from being damaged by sand and gravel splashing when the all-terrain vehicle 100 is traveling on a gravel section, thereby affecting the normal operation of the radiator 151. When the all-terrain vehicle 100 is traveling on a wading section or a muddy section, the heat dissipation shield 152 can also prevent mud from splashing onto the surface of the radiator 151 and causing the radiator 151 to be blocked, thereby improving the working environment of the radiator 151 and further increasing the working life of the radiator 151.

[0086] like Fig.19 As shown, the heat dissipation shield 152 further includes a front shield 1521 and a rear shield 1522, the front shield 1521 is fixedly connected to the rear shield 1522, and when the heat dissipation bracket 113 is in a fixed state, the front shield 1521 and the rear shield 1522 are substantially distributed along the length direction of the all-terrain vehicle 100. The front shield 1521 is substantially located in front of the radiator 151, and the rear shield 1522 is substantially located behind the radiator 151. Further, the rear shield 1522 includes a first guard plate 1522a and a second guard plate 1522b, the first guard plate 1522a and the second guard plate 1522b are distributed along the width direction of the all-terrain vehicle 100, and a hollow portion 1522c is formed between the first guard plate 1522a and the second guard plate 1522b, and when the heat dissipation bracket 113 is in a fixed state, the hollow portion 1522c at least partially overlaps with the radiator 151 when viewed along the length direction of the all-terrain vehicle 100. Through the above arrangement, the design of the hollow portion 1522c ensures that the air outlet of the radiator 151 will not be affected by the rear protective cover 1522, thereby maximizing the air outlet of the radiator 151 and improving the heat dissipation effect of the radiator 151. It can be understood that the front protective cover 1521 and the rear protective cover 1522 are surrounded together to form a heat dissipation accommodation space 1523, and the radiator 151 is at least partially located in the heat dissipation accommodation space 1523 and fixedly connected to the heat dissipation bracket 113.

[0087] In this embodiment, the first guard plate 1522a is provided with an air outlet 1522f. When viewed along the length direction of the all-terrain vehicle 100, the air outlet 1522f at least partially overlaps with the radiator 151. The air outlet 1522f cooperates with the hollow portion 1522c, thereby improving the air guiding efficiency of the radiator 151 and improving the heat dissipation effect of the radiator 151. The heat dissipation assembly 15 also includes a filling pipe 154, which is located on a side of the radiator 151 close to the second guard plate 1522b. The filling pipe 154 is used to fill the radiator 151 with coolant to avoid low heat dissipation efficiency of the radiator 151 due to insufficient coolant. In this application, the filling pipe 154 is fixedly connected to the radiator 151 along the length direction of the all-terrain vehicle 100, so that the filling pipe 154 and the radiator 151 can be connected to each other to reduce the length of the pipeline between the filling pipe 154 and the radiator 151, which is convenient for the arrangement of the pipeline. Optionally, an opening 1522h is formed on the second guard plate 1522b. When viewed along the length direction of the all-terrain vehicle 100, the opening 1522h substantially overlaps with the filling pipe 154, so that the filling pipe 154 can be directly filled with liquid without removing the second guard plate 1522b. Furthermore, a mounting cover 1522g is also formed on the second guard plate 1522b. The mounting cover 1522g can be used to cover the opening 1522h and form a detachable connection with the opening 1522h. More specifically, the mounting cover 1522g is recessed backward to form a groove. When the mounting cover 1522g is connected to the opening 1522h, the filling pipe 154 at least partially passes through the opening 1522h and is located in the mounting cover 1522g. The above arrangement allows the driver to directly remove the mounting cover 1522g to fill the radiator 151 with coolant through the filling pipe 154. The rear protective cover 1522 further includes a first side plate 1522d and a second side plate 1522e, the first side plate 1522d and the second side plate 1522e are distributed along the width direction of the all-terrain vehicle 100, the first side plate 1522d is fixedly connected to the first guard plate 1522a, the second side plate 1522e is fixedly connected to the second guard plate 1522b, and the first side plate 1522d and the second side plate 1522e are substantially parallel to the longitudinal plane 105. When the rear protective cover is in the installed state, the first side plate and the second side plate are respectively located on the left and right sides of the radiator, specifically, the first side plate 1522d and the second side plate 1522e are both provided with air outlets 1522j, and when viewed along the width direction of the all-terrain vehicle 100, the air outlets 1522j and the radiator 151 at least partially overlap, thereby improving the air outlet efficiency of the radiator 151 and preventing the hot air from staying on the radiator 151 for too long to affect the heat dissipation efficiency of the radiator 151.

[0088] In this embodiment, the heat dissipation assembly 15 further includes a filter cover 155. Along the length direction of the all-terrain vehicle 100, the filter cover 155 is located between the front protective cover 1521 and the radiator 151 and is fixedly connected to the front protective cover 1521, that is, the air inlet grille 153, the front protective cover 1521 and the filter cover 155 are basically distributed along the length direction of the all-terrain vehicle 100, and the front protective cover 1521 includes an air inlet 1521a, which is connected to the heat dissipation accommodation space 1523. Along the length direction of the all-terrain vehicle 100, the air inlet 1521a faces the all-terrain vehicle 100. The air inlet 1521a is at the front of the vehicle 100 and the air inlet 1521a overlaps with the filter cover 155 in part at least. The air inlet grille 153 covers the air inlet 1521a. The air inlet grille 153 can prevent debris from entering the radiator 151 through the air inlet 1521a during the air intake process of the radiator 151. The filter cover 155 can perform secondary filtering on the natural wind to prevent small debris from entering the radiator 151. In addition, the air inlet grille 153 can also prevent mud from splashing onto the surface of the radiator 151 through the air inlet 1521a when the all-terrain vehicle 100 is traveling on a wading section or a muddy section. Further, a grille clamping portion 1531 is provided on the air inlet grille 153, and a clamping groove 1521b is provided on the front protective cover 1521. The grille clamping portion 1531 is clamped with the clamping groove 1521b. Through the above arrangement, the grille clamping portion 1531 and the clamping groove 1521b are clamped in such a quick-release manner, so that the connection and separation of the air intake grille 153 and the front protective cover 1521 do not require the use of disassembly or installation tools, thereby greatly simplifying the assembly process of the air intake grille 153, improving the disassembly and assembly speed of the air intake grille 153, and when the driver drives the all-terrain vehicle 100 in the field without maintenance, the driver can also disassemble and assemble the air intake grille 153 by hand. In addition, when the driver or maintenance personnel cleans and maintains the heat dissipation assembly 15, the quick-release design between the air intake grille 153 and the front protective cover 1521 can also effectively reduce the time required for cleaning and maintenance, thereby improving the maintenance performance of the all-terrain vehicle 100.

[0089] like Fig.18As shown, the air inlet grille 153 further includes a plurality of air guide ports 1532 and a plurality of air guide covers 1533. The air guide covers 1533 are all located above the air guide ports 1532. The air guide covers 1533 can change the flow direction of the natural wind, so that the natural wind enters the radiator 151 through the air guide ports 1532 and performs heat exchange with the radiator 151. Specifically, when the heat dissipation bracket 113 is in a fixed state, the air guide covers 1533 basically extend along the length direction of the all-terrain vehicle 100, and the direction of the air guide ports 1532 basically faces the front of the all-terrain vehicle 100, so that the air guide covers 1533 can guide the natural wind, which is convenient for the air intake of the radiator 151. As the air inlet grille 153 rotates with the rotation of the heat dissipation bracket 113, the direction of the air guide 1532 gradually moves toward the bottom of the ATV 100. Since a certain angle is formed between the direction of the air guide 1532 and the flow direction of the natural wind, the air guide cover 1533 can change the flow direction of the natural wind, so that the radiator 151 obtains a larger air intake, thereby improving the heat dissipation effect of the radiator 151. In addition, when the ATV 100 is traveling on a muddy road section, the air guide cover 1533 can also prevent mud from splashing and entering the radiator 151 through the air guide 1532, thereby preventing the radiator 151 from being blocked by mud.

[0090] like Fig. 20 and Fig.21 As shown, the ATV 100 further includes a winch assembly 22, which is at least partially located at the front of the ATV 100. The main function of the winch assembly 22 is to provide additional traction. When the ATV 100 cannot get out of a difficult situation by relying on its own power, the traction provided by the winch assembly 22 enables the ATV 100 to get out of a difficult situation by itself or with the assistance of other ATVs 100, such as a mud pit, a sand dune, or a snowy area. The frame 11 further includes an adapter bracket 115, to which the winch assembly 22 is fixedly connected. The adapter bracket 115 is located in front of the main frame 111, and the adapter bracket 115 is fixedly connected to the main frame 111 by welding or bolting, so as to prevent the tension generated by the winch assembly 22 when working from damaging the frame 11.

[0091] It is understandable that the winch assembly 22 is usually located at the bottom of the ATV 100, that is, when viewed along the width direction of the ATV 100, the winch assembly 22 at least partially overlaps with the front wheel 131, so that the front force point of the ATV 100 is lower, so that when the winch assembly 22 is working, the pulling force of the winch assembly 22 can move the front of the vehicle upward, so that the ATV 100 can escape from danger faster, reduce the difficulty of escaping the ATV 100, and increase the escape speed of the ATV 100. Further, when viewed along the height direction of the ATV 100, the winch assembly 22 at least partially overlaps with the radiator 151. In the conventional layout of the ATV 100, the heat dissipation assembly 15 is usually located behind the lower protective frame 1122, and the winch assembly 22 is located below the heat dissipation assembly 15. When the ATV 100 is stuck in an accident, the winch assembly 22 is easy to sink into the mud together, resulting in the driver trying to use the winch assembly 22 to rescue the vehicle. It is not easy to find the position of the winch assembly 22. In the present application, since the heat dissipation assembly 15 is arranged above the front cover 121, there is space behind the lower protective frame 1122 for arranging the winch assembly 22, that is, the winch assembly 22 of the present application is located behind the lower protective frame 1122, so that when the all-terrain vehicle 100 is stuck in an accident, the position of the winch assembly 22 can be found more easily, thereby reducing the difficulty of rescuing the all-terrain vehicle 100 and improving the efficiency of rescuing the all-terrain vehicle 100.

[0092] Specifically, the line connecting the projections of the rotation centers of the front wheel 131 and the rear wheel 132 on the longitudinal plane 105 is defined as the wheel axle line 106, the projection of the winch assembly 22 on the longitudinal plane 105 along the width direction of the all-terrain vehicle 100 is the winch projection, and the minimum distance H7 between the winch projection and the wheel axle line 106 is 9 cm to 14 cm. More specifically, the minimum distance H7 between the winch projection and the wheel axle line 106 is 10 cm to 13 cm. In this embodiment, the minimum distance H7 between the winch projection and the wheel axle line 106 is 11.6 cm. Since at least part of the electrical component 21 is also arranged above the winch assembly 22, if the minimum distance H7 between the winch projection and the wheel axle connection line 106 is too large, it is easy to cause the position of the winch assembly 22 to be too high, causing the winch assembly 22 and the electrical component 21 to interfere with each other, and it is also easy to cause the position of the winch assembly 22 to be too high, causing the front of the all-terrain vehicle 100 to sink due to the excessively high force point of the front of the vehicle during the rescue process of the all-terrain vehicle 100, making it difficult to rescue the all-terrain vehicle 100. If the minimum distance H7 between the winch projection and the wheel axle connection line 106 is too small, it is easy to cause the winch assembly 22 to be too low, which is not conducive to the driver finding the position of the winch assembly 22 after the all-terrain vehicle 100 is stuck. Through the above-mentioned settings, it is possible to avoid interference between the winch assembly 22 and the electrical component 21, improve the rescue efficiency of the all-terrain vehicle 100, and make it easier for the driver to find the position of the winch assembly 22.

[0093] In this embodiment, the winch assembly 22 includes a winch motor 221, a winch rope 222 and a winch hook 223. The winch motor 221 is fixedly connected to the main frame through the adapter bracket 115. One end of the winch rope 222 is connected to the rotating shaft of the winch motor 221, and the other end of the winch rope 222 is connected to the winch hook 223. When the all-terrain vehicle 100 needs to be rescued, the winch hook 223 is hung on a fixed object, and the winch rope 222 is tightened by the winch motor 221, so that the all-terrain vehicle 100 receives a pulling force to help the all-terrain vehicle 100 get out of trouble. In addition, when a fellow vehicle needs to be rescued, the winch assembly 22 of the all-terrain vehicle 100 can also be connected to the towing point of the vehicle through the winch hook 223, and the winch rope 222 is tightened by the winch motor 221 to help the fellow vehicle get out of trouble. The winch assembly 22 also includes a winch mounting frame 224, which is fixedly connected to the lower protective frame 1122. A wire outlet 2241 is provided on the winch mounting frame 224. The winch rope 222 extends forward and passes through the wire outlet 2241. The width of the wire outlet 2241 is greater than the outer diameter of the winch rope 222 and less than the thickness of the winch hook. Therefore, the wire outlet 2241 allows the winch rope 222 to pass through while preventing the winch hook 223 from passing through. When the winch rope 222 is stored in the rotating shaft of the winch motor 221, the winch hook 223 is suspended in front of the wire outlet 2241 through the winch rope 222. A starting switch (not shown) is also provided on the winch motor 221. When the driver needs, the starting switch can be directly turned on, and the winch rope 222 can be pulled out from the winch motor 221 by pulling the winch hook 223, thereby improving the rescue efficiency of the all-terrain vehicle 100. The winch mounting frame 224 is also provided with two towing holes 2242, which are located on both sides of the outlet 2241 along the width direction of the all-terrain vehicle 100. The towing holes 2242 are used to install the winch hook 223, thereby providing a towing point for the all-terrain vehicle 100. When the all-terrain vehicle 100 needs to be rescued, it can be rescued by other vehicles traveling with it.

[0094] Furthermore, along the width direction of the all-terrain vehicle 100, the projection of the winch motor 221 on the longitudinal plane 105 is defined as the motor projection, and the minimum distance between the motor projection and the wheel axle line 106 is equal to the minimum distance between the middle winch projection and the wheel axle line 106, that is, the minimum distance between the motor projection and the wheel axle line 106 is the minimum distance H7 between the middle winch projection and the wheel axle line 106, and the projection of the outlet 2241 on the longitudinal plane 105 along the width direction of the all-terrain vehicle 100 is defined as the motor projection. The shadow is defined as the projection of the outlet, and the minimum distance H8 between the outlet projection and the wheel axle line 106 is greater than the minimum distance H7 between the motor projection and the wheel axle line 106, so that the tension received by the all-terrain vehicle 100 when the winch rope 222 is pulled in has an upward component along the height direction of the all-terrain vehicle 100, and then in the process of the winch rope 222 pulling the all-terrain vehicle 100, the front of the all-terrain vehicle 100 can gradually move upward and away from the mud, thereby improving the escape efficiency of the all-terrain vehicle 100.

[0095] like Fig. 22 , Fig.23 and Fig.24 As shown, the power assembly 14 also includes a transmission 142, which is connected to the engine 141 in a transmission manner. The transmission 142 is used to change the speed output by the engine 141 so that the speed better matches the current driving environment. In the present application, the transmission 142 refers to the continuously variable transmission 142, which generates heat during operation. Therefore, it is necessary to dissipate heat from the transmission 142 to avoid the operating temperature of the transmission 142 being too high and causing damage to the transmission 142. Specifically, the transmission 142 includes a transmission intake pipe 1421 and a transmission exhaust pipe 1422. Natural wind enters the interior of the transmission 142 through the transmission intake pipe 1421 and completes heat exchange inside the transmission 142, and then the hot air is discharged from the transmission exhaust pipe 1422, thereby reducing the temperature of the transmission 142 and keeping the transmission 142 at a suitable operating temperature, thereby improving the working efficiency of the transmission 142.

[0096] like Fig.23 and Fig.24As shown, it can be understood that when the all-terrain vehicle 100 is traveling on a muddy road section, if water enters the transmission 142, it is easy to cause the transmission 142 to slip, thereby affecting the power output. In order to enable the all-terrain vehicle 100 of the present application to travel on muddy roads and wading roads, it is necessary to adjust the positions of the transmission air intake pipe 1421 and the transmission exhaust pipe 1422 to prevent muddy water from entering the transmission 142 from the transmission air intake pipe 1421 and the transmission exhaust pipe 1422 when the all-terrain vehicle 100 is traveling on a muddy road section, thereby causing damage to the transmission 142. Specifically, when observing from the height direction of the all-terrain vehicle 100, the transmission air intake pipe 1421 and the transmission exhaust pipe 1422 both extend substantially along the length direction of the all-terrain vehicle 100, and the transmission air intake pipe 1421 and the transmission exhaust pipe 1422 are distributed along the width direction of the all-terrain vehicle 100. Observing along the width direction of the all-terrain vehicle 100, the speed-changing air intake pipe 1421 and the speed-changing exhaust pipe 1422 are also at least partially located above the engine 141, and the speed-changing air intake pipe 1421 is also at least partially located above the engine 141, and the speed-changing exhaust pipe 1422 extends from the rear of the engine 141 to the front of the engine 141. Through the above arrangement, the speed-changing air intake pipe 1421 and the speed-changing exhaust pipe 1422 are located above the engine 141 and arranged along the length direction of the all-terrain vehicle 100, which can effectively reduce the length of the pipeline, thereby facilitating the arrangement of the speed-changing air intake pipe 1421 and the speed-changing exhaust pipe 1422 on the all-terrain vehicle 100, making the whole vehicle more compact, thereby improving the space utilization of the all-terrain vehicle 100.

[0097] Furthermore, the speed-changing air intake pipe 1421 includes a speed-changing air intake port 1421a, and the speed-changing exhaust pipe 1422 includes a speed-changing exhaust port 1422a. Natural wind enters the speed-changing air intake pipe 1421 through the speed-changing air intake port 1421a, and hot air passes through the speed-changing exhaust pipe 1422 and is discharged from the speed-changing exhaust port 1422a. The speed-changing air intake port 1421a and the speed-changing exhaust port 1422a are both located behind the heat dissipation assembly 15, and the speed-changing air intake port 1421a and the speed-changing exhaust port 1422a are both arranged near the steering assembly 16. The vehicle body cover 12 also includes a main cover 125 for covering the power assembly 14, and the main cover 125 is at least partially located below the instrument surface cover 122; the speed-changing air intake port 1421a is at least partially located outside the main cover 125, and the speed-changing exhaust port 1422a is located inside the main cover 125. The vehicle body cover 12 also includes a front cover plate 126 located in front of the instrument panel 122, the transmission air inlet is located above the front cover plate 126, and the transmission exhaust port 1422a is located below the front cover plate 126, thereby separating the transmission exhaust port 1422a and the transmission air inlet 1421a to prevent the high-temperature gas discharged from the transmission exhaust port 1422a from affecting the air intake of the transmission air inlet 1421a. The power assembly 14 further includes an air filter 143 to filter the air entering the engine 141. The air filter 143 is at least partially located above the engine 141 and communicates with the engine 141. The air filter 143 includes an air filter intake pipe 1431. The air filter intake pipe 1431 is at least partially located in front of the air filter 143. The air filter intake pipe 1431 is also located above the engine 141 and the transmission 142 and extends upward. Along the width direction of the all-terrain vehicle 100, the air filter intake pipe 1431 is located between the transmission intake pipe 1421 and the transmission 142. The air filter intake pipe 1431 includes an air filter intake port 1431a, which is at least partially located above the instrument panel 122. The air filter intake port 1431a is also at least partially located in front of the steering handle 161. The speed intake port 1421a and the speed exhaust port 1422a are at least partially located behind the air filter intake port 1431a. When viewed along the width direction of the all-terrain vehicle 100, the speed intake port 1421a and the speed exhaust port 1422a also at least partially overlap with the instrument panel 122. Through the above-mentioned arrangement, since the air filter inlet 1431a is basically located at the top of the all-terrain vehicle 100, the speed shift inlet 1421a and the speed shift exhaust port 1422a are located on both sides of the air filter inlet 1431a, the distance between the speed shift inlet 1421a and the speed shift exhaust port 1422a and the ground can be increased, thereby preventing mud and water from entering the speed shift inlet 1421a and the speed shift exhaust port 1422a and then entering the transmission 142 through the speed shift inlet pipe 1421 and the speed shift exhaust pipe 1422, thereby increasing the wading height of the all-terrain vehicle 100 and improving the passability of the all-terrain vehicle 100 on muddy roads.

[0098] In this embodiment, the speed change air inlet 1421a is generally oriented downward along the height direction of the ATV 100, so that after muddy water enters the speed change air inlet 1421a, the speed change air inlet 1421a is oriented downward, and the muddy water can flow out of the speed change air inlet 1421a under the action of gravity, thereby preventing the muddy water from entering the transmission 142. It can be understood that the "outside of the ATV 100" in the foregoing refers to the side away from the longitudinal plane 105 along the width direction of the ATV 100. In this embodiment, the speed change exhaust port 1422a is oriented toward the outside of the ATV 100 along the width direction of the ATV 100, thereby preventing the hot air in the speed change exhaust pipe 1422 from staying in the ATV 100 for too long. The speed shift exhaust pipe 1422 also includes an adapter 1422b, which is arranged on the speed shift exhaust port 1422a. The adapter 1422b is basically facing downward along the height direction of the all-terrain vehicle 100, so that like the speed shift air inlet 1421a, after mud and water enter the adapter 1422b, they can flow out from the adapter 1422b due to their own gravity, thereby preventing mud and water from entering the speed shift exhaust pipe 1422 and affecting the normal operation of the transmission 142.

[0099] Further, the transmission exhaust pipe 1422 includes a first pipe 1422c and a second pipe 1422d which are fixedly connected to each other, the first pipe 1422c is connected to the interior of the transmission 142, the first pipe 1422c is located behind the second pipe 1422d and is connected to the second pipe 1422d, the second pipe 1422d extends substantially along the length direction of the all-terrain vehicle 100, and the second pipe 1422d is also connected to the transfer port 1422b. Among them, the material hardness of the first pipe 1422c is greater than that of the second pipe 1422d. Specifically, the first pipe 1422c can be set as a rubber tube, so as to avoid interference with other surrounding components due to installation errors, thereby improving the space utilization rate of the all-terrain vehicle 100. In addition, the inner diameter of the first pipe 1422c can be enlarged, so as to increase the ventilation volume of the first pipe 1422c, improve the heat dissipation efficiency of the transmission 142, and further improve the working efficiency of the transmission 142.

[0100] like Fig.25As shown, as an embodiment, the body cover 12 also includes an air intake plastic part 127, which is located above the instrument surface cover, and the air filter air intake pipe 1431 is fixedly connected to the air intake plastic part 127, and three connecting ports are formed on the air intake plastic part 127. In the present application, one end of the air intake plastic part 127 is respectively connected to the speed change air intake pipe 1421, the speed change exhaust pipe 1422 and the air filter air intake pipe 1431, that is, the three connecting ports of the air intake plastic part are respectively formed as the speed change air intake port 1421a, the transmission exhaust port 1422a and the air filter air intake port 1431a, so that the speed change air intake port 1421a, the speed change exhaust port 1422a and the air filter air intake port 1431a are arranged in the same area through the air intake plastic part 127, so as to facilitate the arrangement of each air intake port and exhaust port, reduce the difficulty of mold opening of plastic parts of the all-terrain vehicle 100, and improve the space utilization rate of the all-terrain vehicle 100. Among them, the speed change air inlet 1421a and the air filter air inlet 1431a are oriented toward the rear of the ATV 100 . This arrangement can effectively prevent mud and water in front of the ATV 100 from entering the air inlet and affecting the operation of the engine 141 .

[0101] like Fig.26 As shown, optionally, in order to prevent the hot air in the speed-changing exhaust port 1422a from affecting the temperature of the natural wind in the air filter inlet port 1431a and the speed-changing air inlet port 1421a, only two air inlets can be formed on the air inlet plastic part 127. In the present application, one end of the air inlet plastic part 127 is respectively connected to the speed-changing air inlet pipe 1421 and the air filter inlet pipe 1431, that is, the two air inlets of the air inlet plastic part 127 are respectively formed as the speed-changing air inlet port 1421a and the air filter inlet port 1431a, so that the speed-changing air inlet port 1421a and the air filter inlet port 1431 can be connected to each other. By arranging the air intake plastic part 127 in the same area, the speed change exhaust port 1422a is arranged separately, which reduces the difficulty of opening the mold of the plastic parts of the all-terrain vehicle 100 and improves the space utilization of the all-terrain vehicle 100. At the same time, the speed change exhaust port 1422a is kept away from the speed change air intake port 1421a and the air filter air intake port 1431a, thereby avoiding the increase of the natural wind temperature in the speed change air intake port 1421a and the air filter air intake port 1431a due to the excessively high hot air temperature in the speed change exhaust port 1422a, which reduces the heat dissipation efficiency of the transmission 142.

[0102] like Fig. 27As shown, as another optional implementation, the speed-shift air inlet 1421a and the speed-shift exhaust port 1422a can also be distributed on both sides of the air filter inlet 1431a along the width direction of the all-terrain vehicle 100. The speed-shift air inlet 1421a, the speed-shift exhaust port 1422a and the air filter inlet 1431a are independently arranged. Compared with the fixed speed-shift air inlet 1421a and the speed-shift exhaust port 1422a, the arrangement of the speed-shift air inlet pipe 1421 and the speed-shift exhaust pipe 1422 is relatively limited, and the direction of the pipeline is relatively fixed, so that the arrangement of the speed-shift air inlet pipe 1421 and the speed-shift exhaust pipe 1422 is relatively fixed, and the arrangement of other components needs to be changed to avoid mutual interference, which easily leads to waste of space of the all-terrain vehicle 100. The transmission air intake pipe 1421 and the transmission exhaust pipe 1422 of this embodiment are arranged relatively freely, so that the transmission air intake pipe 1421 and the transmission exhaust pipe 1422 can be adjusted according to the actual arrangement of the all-terrain vehicle 100, thereby improving the space utilization of the all-terrain vehicle 100. Furthermore, the transmission air intake port 1421a and the transmission exhaust port 1422a are shielded by the vehicle body cover 12, so that while air is being taken in and exhausted, water splashing into the transmission air intake port 1421a and the transmission exhaust port 1422a can be prevented from affecting the normal operation of the transmission 142 due to water ingress into the transmission air intake port 1421a and the transmission exhaust port 1422a.

[0103] 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.
