Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and particularly to an all-terrain vehicle. Background Art

[0002] An all-terrain vehicle is a multi-functional vehicle designed for various complex terrains. It has powerful off-road capabilities and stability, and can easily travel in complex environments such as mud, sand, snow, and rocks.

[0003] An all-terrain vehicle generally includes a frame, a body cover, a running system, a suspension system, a power assembly, and electrical components. In the prior art, the heat dissipation of the power assembly of an all-terrain vehicle depends on the intake of air through the front grille at the front and the front wheels on both sides to dissipate heat from the power assembly. However, since mudguards are usually installed at the front of an all-terrain vehicle to block sediment and moisture, the mudguards will hinder the intake of air at the front grille and the front wheels, thereby reducing the heat dissipation effect on the power assembly, and further causing the overall temperature of the power assembly and the all-terrain vehicle to be too high, reducing the riding comfort of the all-terrain vehicle.

[0035] As Figure 1 and Figure 2 shown, this application provides an all-terrain vehicle 100, which includes a frame 11, a body covering 12, a running system 13, a suspension system 14, a power assembly 15, a transmission assembly 16, a fuel assembly 17, a seat assembly 19, a steering system 20 and an electrical assembly 22.

[0036] To clearly illustrate the technical solution of this application, the front, rear, left, right, upper and lower as Figure 1 shown are also defined. In this application, the length direction of the frame 11 refers to the Figure 1 front-rear direction in Figure 1 , the width direction of the frame 11 refers to the Figure 1 left-right direction in

[0037] Among them, the vehicle frame 11 serves as the basic frame of the all-terrain vehicle 100 and is used to support the body cover 12, the running system 13, the suspension system 14, the power assembly 15, the transmission assembly 16, the fuel assembly 17, the seat assembly 19, the steering system 20, and the electrical assembly 22. The body cover 12 is at least partially located on the vehicle frame 11 and connected to the vehicle frame 11 so that the body cover 12 can protect the components inside the all-terrain vehicle 100. The running system 13 is at least partially located below the vehicle frame 11, and the suspension system 14 connects the running system 13 to the vehicle frame 11. Specifically, the running system 13 includes a front wheel 132 and a rear wheel 133 that are at least partially located below the vehicle frame 11, and both the front wheel 132 and the rear wheel 133 are connected to the vehicle frame 11 through the suspension system 14. The power assembly 15 is in transmission connection with the running system 13. Specifically, the transmission assembly 16 transmits the power assembly 15 to the running system 13. The fuel assembly 17 includes a fuel tank 171, and the fuel tank 171 is used to supply energy to the power assembly 15. Specifically, the fuel tank 171 is used to deliver fuel to the power assembly 15. The steering system 20 is supported by the vehicle frame 11 and is used for the steering of the all-terrain vehicle 100. The electrical assembly 22 is supported by the vehicle frame 11. The electrical assembly 22 is supported by the body cover 12 or the vehicle frame 11, and the electrical assembly 22 is used to display the driving data of the all-terrain vehicle 100, control the operation of the all-terrain vehicle 100, etc. The seat assembly 19 is supported by the vehicle frame 11, and the seat assembly 19 is used to support the driver and / or passengers.

[0038] As Figure 3 and Figure 4 shown, as an implementation, the power assembly 15 includes a continuously variable transmission mechanism 152 and an engine 151. The engine 151 is in transmission connection with the continuously variable transmission mechanism 152, and the continuously variable transmission mechanism 152 is in transmission connection with the running system 13, thereby driving the running system 13 to drive the all-terrain vehicle 100 to travel. The heat dissipation assembly 25 includes a heat dissipation duct 253, and the heat dissipation duct 253 is used to direct the air outside the all-terrain vehicle 100 to the continuously variable transmission mechanism 152, thereby cooling and dissipating heat from the continuously variable transmission mechanism 152.

[0039] Specifically, the heat dissipation duct 253 includes an air inlet 2531 and an air outlet 2532. The heat dissipation duct 253 is configured to convey the external air to the continuously variable transmission mechanism 152 through the air inlet 2531 and the air outlet 2532. The body covering 12 includes a front fender 126, and the running system 13 includes a front wheel 132. The front fender 126 is located above the front wheel 132. When observed in the height direction of the frame 11, the front fender 126 at least partially overlaps with the front wheel 132. The front fender 126 is used to block sediment, gravel, etc. The air inlet 2531 is installed on the front fender 126, and the external air enters the heat dissipation duct 253 from the air inlet 2531. The air outlet 2532 is arranged towards the continuously variable transmission mechanism 152, and the air that enters the heat dissipation duct 253 from the air inlet 2531 is discharged from the air outlet 2532 and reaches the continuously variable transmission mechanism 152.

[0040] Since a large amount of heat is generated during the operation of the continuously variable transmission mechanism 152, which leads to an excessively high temperature of the continuously variable transmission mechanism 152, and the cooling effect of the existing cooling and heat dissipation structure on the continuously variable transmission mechanism 152 is insufficient, the heat dissipation duct 253 is added to improve the cooling and heat dissipation effect on the continuously variable transmission mechanism 152. After the external air is conveyed to the continuously variable transmission mechanism 152 through the heat dissipation duct 253, the heat of the continuously variable transmission mechanism 152 is carried away, thus playing a role in improving the cooling and heat dissipation effect of the continuously variable transmission mechanism 152, and further reducing the overall vehicle temperature of the all-terrain vehicle 100.

[0041] As an implementation manner, the opening of the air inlet 2531 is basically set facing forward. Since an air flow from front to back will be generated around the all-terrain vehicle 100 during driving, setting the opening of the air inlet 2531 basically facing forward can enable the external air to smoothly enter the heat dissipation duct 253 from the air inlet 2531 and form an air flow flowing from the air inlet 2531 to the air outlet 2532 in the heat dissipation duct 253, thereby improving the cooling and heat dissipation effect of the continuously variable transmission mechanism 152.

[0042] In this application, a filtering structure is provided in the air inlet 2531. The filtering structure is used to block sediment, gravel, etc. from entering the heat dissipation duct 253, thereby preventing sediment, gravel, etc. from entering the continuously variable transmission mechanism 152, causing collision and wear to the continuously variable transmission mechanism 152, and further preventing damage to the continuously variable transmission mechanism 152. In this application, the filtering structure is a filter screen, etc.

[0043] As an implementation, the all-terrain vehicle 100 includes a cargo box assembly 21. The cargo box assembly 21 includes a cargo box 211 and a front cargo box mounting plate 212. The front cargo box mounting plate 212 is used to mount the cargo box 211. The front fender 126 has a mounting surface 1261. The front cargo box mounting plate 212 is mounted on the mounting surface 1261 and there is a gap 254 between the front cargo box mounting plate 212 and the mounting surface 1261. The air inlet 2531 is located within the gap 254. The above arrangement enables external air to enter the air inlet 2531 through the gap 254 between the front cargo box mounting plate 212 and the mounting surface 1261 of the front fender 126. The air inlet 2531 is arranged within the gap 254 to block most of the sediment, gravel, etc. from entering the air inlet 2531 into the heat dissipation duct 253, thereby preventing sediment, gravel, etc. from entering the continuously variable transmission mechanism 152 and causing collision and wear to the continuously variable transmission mechanism 152, and further preventing damage to the continuously variable transmission mechanism 152. At the same time, with the air inlet 2531 arranged within the gap 254, external air can enter the air inlet 2531 through the gap 254, thus not affecting the air intake effect of the heat dissipation duct 253. In addition, the above arrangement can also enable the air inlet 2531 to be arranged using the gap 254, making the structure of the all-terrain vehicle 100 more compact and improving the space utilization rate of the all-terrain vehicle 100.

[0044] As an implementation, the power assembly 15 further includes a transmission intake pipe 153. The transmission intake pipe 153 is connected to the continuously variable transmission mechanism 152 and is used to intake air into the continuously variable transmission mechanism 152. When observed from the width direction of the frame 11, the transmission intake pipe 153 at least partially overlaps with the heat dissipation duct 253 to avoid interference between the transmission intake pipe 153 and the heat dissipation duct 253, and improves the compactness of the internal structure of the all-terrain vehicle 100.

[0045] Specifically, the all-terrain vehicle 100 further includes a fuel assembly 17. The fuel assembly 17 includes a fuel tank 171 and a fuel filling port 172. The fuel filling port 172 is connected to the fuel tank 171 and is located above the fuel tank 171. Along the width direction of the frame 11, the heat dissipation duct 253 is at least partially located between the fuel filling port 172 and the transmission intake pipe 153. The heat dissipation duct 253 is interposed between the fuel filling port 172 and the transmission intake pipe 153 to avoid interference between the heat dissipation duct 253, the fuel filling port 172, and the transmission intake pipe 153, and improves the compactness of the internal structure of the all-terrain vehicle 100.

[0046] More specifically, at least a part of the heat dissipation duct 253 is bent to form a bent portion 2533a. The bent portion 2533a is configured to be able to avoid the fuel filling port 172. The arrangement of the bent portion 2533a avoids interference between the heat dissipation duct 253 and the fuel filling port 172 and further improves the compactness of the internal structure of the all-terrain vehicle 100.

[0047] More specifically, the bent portion 2533a is fixedly connected to the vehicle frame 11. The connection method between the bent portion 2533a and the vehicle frame 11 can be welding or bolt connection, etc., so as to improve the stability of the heat dissipation duct 253 during the driving of the all-terrain vehicle 100.

[0048] As an implementation manner, the heat dissipation duct 253 includes an integrally formed round tube portion 2533 and a flat tube portion 2534. The round tube portion 2533 communicates with the air inlet 2531, and the flat tube portion 2534 communicates with the air outlet 2532. The flat tube portion 2534 is configured to be able to reduce the thickness of the heat dissipation duct 253 in a preset direction. The above preset direction can be in any direction. The setting of the flat tube portion 2534 enables the heat dissipation duct 253 to pass through the narrow gaps between the internal structures of the all-terrain vehicle 100, so as to avoid interference with the internal structures of the all-terrain vehicle 100, thereby making full use of the limited space and improving the space utilization rate inside the all-terrain vehicle 100.

[0049] It should be noted that the bent portion 2533a is located on the round tube portion 2533, so that the internal channel at the bent portion 2533a will not be too narrow, thereby reducing the flow resistance of air in the heat dissipation duct 253, and further improving the heat dissipation effect on the continuously variable transmission mechanism 152.

[0050] Specifically, along the width direction of the vehicle frame 11, at least a part of the flat tube portion 2534 is located between the transmission intake pipe 153 and the vehicle frame 11. The thickness of the flat tube portion 2534 along the width direction of the vehicle frame 11 is less than the thickness of the flat tube portion 2534 along the height direction of the vehicle frame 11. The gap between the transmission intake pipe 153 and the vehicle frame 11 is small. The setting of the flat tube portion 2534 enables the heat dissipation duct 253 to pass through the gap between the transmission intake pipe 153 and the vehicle frame 11, and the heat dissipation duct 253 will not interfere with the transmission intake pipe 153 and the vehicle frame 11, thereby making full use of the limited space and improving the space utilization rate inside the all-terrain vehicle 100.

[0051] More specifically, the flat tube portion 2534 is fixedly connected to the vehicle frame 11. The connection method between the flat tube portion 2534 and the vehicle frame 11 can be welding or bolt connection, etc., further improving the stability of the heat dissipation duct 253 during the driving of the all-terrain vehicle 100.

[0052] Such as Figure 5 、 Figure 6 and Figure 7As shown, as an implementation, the body covering 12 includes a lower guard plate 12h. The lower guard plate 12h is located below the frame 11 and fixedly connected to the frame 11, so that the lower guard plate 12h can protect the lower part of the all-terrain vehicle 100 to prevent impurities such as stones and muddy water from damaging the internal components of the all-terrain vehicle 100. Among them, the lower guard plate 12h is at least partially located below the power assembly 15, and the lower guard plate 12h is substantially perpendicular to the height direction of the frame 11, so that the lower guard plate 12h will not affect the installation of the power assembly 15 and further improves the protection effect on the power assembly 15.

[0053] The lower guard plate 12h is provided with heat dissipation holes 12ha. The heat dissipation holes 12ha are arranged facing the power assembly 15, and when observed from the height direction of the frame 11, the heat dissipation holes 12ha at least partially overlap with the power assembly 15. Therefore, during the driving process of the all-terrain vehicle 100, the external air can be conveyed to the upper part of the lower guard plate 12h through the heat dissipation holes 12ha, so that the external air can be conveyed to the power assembly 15, thereby improving the heat dissipation effect of the power assembly 15.

[0054] Specifically, the lower guard plate 12h is provided with heat dissipation grooves 12hb. The openings of the heat dissipation grooves 12hb are arranged downward. The heat dissipation grooves 12hb have a front side wall 12hc that is substantially a convex curved surface. The front side wall 12hc includes a front end 12hr and a rear end 12hs. The height of the rear end 12hs is higher than that of the front end 12hr. The front end 12hr is located at the opening of the heat dissipation groove 12hb, and the rear end 12hs is connected to the bottom of the heat dissipation groove 12hb. The bottom of the heat dissipation groove 12hb is provided with heat dissipation holes 12ha. The above settings can make the external air be conveyed from the front end 12hr of the front side wall 12hc along the front side wall 12hc to the rear end 12hs of the front side wall 12hc, and be conveyed from the rear end 12hs of the front side wall 12hc to the power assembly 15 through the heat dissipation holes 12ha at the bottom of the heat dissipation groove 12hb, thereby realizing the heat dissipation of the power assembly 15. Among them, the convex curved front side wall 12hc can have a guiding effect on the external air, so that the air intake volume of the air entering the heat dissipation holes 12ha can be increased, and the heat dissipation effect on the power assembly 15 can be further improved.

[0055] Define a preset straight line 12hd connecting the front end 12hr and the rear end 12hs, and define a plane perpendicular to the width direction of the frame 11 and passing through the midpoint of the width of the frame 11 as the longitudinal center plane 10s of the frame 11 (refer to Figure 14) The longitudinal central plane 10s defines a reference plane 102 perpendicular to the height direction of the vehicle frame 11. The orthographic projection of the reference plane 102 on the longitudinal central plane 10s is a horizontal line. The orthographic projection of the preset straight line 12hd on the longitudinal central plane 10s is the sidewall connection line. The included angle σ formed by the sidewall connection line and the horizontal line ranges from 23° to 40°, and the opening of the included angle is set backward. Specifically, the included angle σ formed by the sidewall connection line and the horizontal line ranges from 26° to 36°. More specifically, the included angle σ formed by the sidewall connection line and the horizontal line is 33°.

[0056] Through the above settings, it can be avoided that the included angle σ formed by the sidewall connection line and the horizontal line is too small, resulting in an excessively long length of the front sidewall 12hc along the length direction of the vehicle frame 11. Thus, it can be avoided that the excessive length of the front sidewall 12hc reduces the structural strength of the lower guard plate 12h, and it can be avoided that the excessive length of the front sidewall 12hc causes air to leak to the outside, thereby improving the heat dissipation effect of the heat dissipation holes 12ha on the power assembly 15. At the same time, the above settings can also avoid that the included angle σ formed by the sidewall connection line and the horizontal line is too large, resulting in an excessively large thickness of the lower guard plate 12h along the height direction of the vehicle frame 11, thereby avoiding interference of the lower guard plate 12h with the components inside the all-terrain vehicle 100.

[0057] As an implementation manner, the heat dissipation groove 12hb has a first sidewall 12he and a second sidewall 12hf distributed along the width direction of the vehicle frame 11. The first sidewall 12he, the second sidewall 12hf, and the front sidewall 12hc surround and form an air intake passage 12hg. The air intake passage 12hg is configured to be able to convey the outside air into the heat dissipation holes 12ha. The above settings can enable the outside air to be restricted in the air intake passage 12hg to avoid leakage of the outside air, thereby increasing the air intake volume at the heat dissipation holes 12ha and further improving the heat dissipation effect on the power assembly 15.

[0058] Specifically, the heat dissipation groove 12hb has a rear sidewall 12hj for sealing the rear of the air intake passage 12hg. The rear sidewall 12hj is configured to be able to block the outside air from leaking out of the air intake passage 12hg. At the same time, the above settings can also enable the outside air to be blocked by the rear sidewall 12hj so that the outside air can flow into the heat dissipation holes 12ha.

[0059] In the present application, a grille structure 12hk is provided at the bottom of the heat dissipation groove 12hb. The gaps between the grille structures 12hk form the heat dissipation holes 12ha. The grille structure 12hk is used to block foreign matters such as stones and muddy water from the outside from entering above the lower guard plate 12h, thereby avoiding damage to the power assembly 15 and the like caused by foreign matters from the outside.

[0060] As an alternative implementation, the lower guard plate 12h includes a first guard plate 12hm and a second guard plate 12hn located behind the first guard plate 12hm. The second guard plate 12hn is at least partially located below the power assembly 15. Both the first guard plate 12hm and the second guard plate 12hn are provided with heat dissipation grooves 12hb and heat dissipation holes 12ha. Among them, the separately arranged lower guard plate 12h can be adjusted according to the assembly requirements, which is beneficial to the assembly of the lower guard plate 12h.

[0061] Specifically, the power assembly 15 includes a continuously variable transmission mechanism 152 and an engine 151. The heat dissipation holes 12ha of the first guard plate 12hm are arranged facing the engine 151, and the heat dissipation holes 12ha of the second guard plate 12hn are arranged facing the continuously variable transmission mechanism 152, so that the heat dissipation holes 12ha on the first guard plate 12hm can dissipate heat from the engine 151, and the heat dissipation holes 12ha on the second guard plate 12hn can dissipate heat from the continuously variable transmission mechanism 152.

[0062] In this embodiment, the heat dissipation groove 12hb includes a first heat dissipation groove 12hp. The first guard plate 12hm includes a plurality of first heat dissipation grooves 12hp. The plurality of first heat dissipation grooves 12hp are distributed along the width direction of the vehicle frame 11. The heat dissipation holes 12ha on the plurality of first heat dissipation grooves 12hp are all arranged facing the engine 151 to improve the heat dissipation efficiency of the engine 151.

[0063] In this embodiment, the continuously variable transmission mechanism 152 and the engine 151 are distributed along the width direction of the vehicle frame 11. The heat dissipation groove 12hb includes a second heat dissipation groove 12hq. At least one second heat dissipation groove 12hq is provided on the second guard plate 12hn. When observed from the height direction of the vehicle frame 11, the heat dissipation holes 12ha on the second heat dissipation groove 12hq at least partially overlap with the continuously variable transmission mechanism 152, so that the second heat dissipation groove 12hq can better deliver the outside air to the continuously variable transmission mechanism 152 through the heat dissipation holes 12ha, thereby improving the heat dissipation efficiency of the continuously variable transmission mechanism 152.

[0064] Such as Figure 8 and Figure 9As shown, as an implementation manner, the body covering member 12 further includes a first covering side cover 1206 and a second covering side cover 1207. Specifically, the storage box assembly 1205, the first covering side cover 1206, and the second covering side cover 1207 are all at least partially supported by the vehicle frame 11. Along the length direction of the vehicle frame 11, the storage box assembly 1205, the first covering side cover 1206, and the second covering side cover 1207 are all at least partially located between the front fender 126 and the seat assembly 19. The first covering side cover 1206 and the second covering side cover 1207 are distributed on both sides of the storage box assembly 1205 along the width direction of the vehicle frame 11. Among them, a first space 1206a is formed by surrounding the first covering side cover 1206 and the front fender 126, and a second space 1207a is formed by surrounding the second covering side cover 1207 and the front fender 126. With such an arrangement, the first space 1206a and the second space 1207a can provide layout space for components, thereby facilitating the improvement of the space utilization rate at the first covering side cover 1206 and the second covering side cover 1207.

[0065] More specifically, the storage box assembly 1205 is at least partially located in the first space 1206a and / or the second space 1207a. With such an arrangement, the storage box assembly 1205 can utilize the layout space provided by the first space 1206a and / or the second space 1207a, thereby increasing the space occupancy rate of the storage box assembly 1205, and further increasing the storage volume of the storage box assembly 1205, which is beneficial to improving the storage function of the all-terrain vehicle 100.

[0066] In this implementation manner, the volume range of the storage box assembly 1205 is 6L to 10L. Specifically, the volume range of the storage box assembly 1205 is 7L to 9L. More specifically, the volume of the storage box assembly 1205 is 8L. Through the above settings, it is possible to avoid the volume range of the storage box assembly 1205 being too large, which may cause interference with other components in the first space 1206a and the second space 1207a, thereby facilitating the improvement of the space utilization rate in the first space 1206a and the second space 1207a; it is also possible to avoid the volume range of the storage box assembly 1205 being too small, which may reduce the storage space of the storage box assembly 1205, and further improve the storage performance of the storage box assembly 1205.

[0067] As Figure 8 shown, as an implementation manner, the powertrain 15 further includes an air filter mechanism (not shown in the figure), a continuously variable transmission (CVT) (refer to Figure 3) An air filter intake pipe 155 and a continuously variable transmission intake pipe 153. Among them, the air filter mechanism is used to remove particulate impurities in the air. The air filter intake pipe 155 is connected to the air filter mechanism, and the air filter intake pipe 155 is used to convey air to the air filter mechanism. The continuously variable transmission mechanism is used to adjust the transmission ratio. The continuously variable transmission intake pipe 153 is connected to the continuously variable transmission mechanism, and the continuously variable transmission intake pipe 153 is used to supply gas to the continuously variable transmission mechanism. Specifically, when observing from the height direction of the vehicle frame 11, the storage box assembly 1205 at least partially overlaps with the air filter intake pipe 155, and the storage box assembly 1205 at least partially overlaps with the continuously variable transmission intake pipe 153. With such a setting, the structural compactness at the storage box assembly 1205 can be improved.

[0068] In this embodiment, both the air filter intake pipe 155 and the continuously variable transmission intake pipe 153 are at least partially located below the storage box assembly 1205. With such a setting, it is possible to avoid interference of the air filter intake pipe 155 and the continuously variable transmission intake pipe 153 when taking items from the storage box assembly 1205, which is beneficial to improving the convenience of use of the storage box assembly 1205.

[0069] As Figure 8 and Figure 9 shown, as an embodiment, the maximum distance D8 of the first covering side cover 1206 and the second covering side cover 1207 in the width direction of the vehicle frame 11 is greater than the maximum width W1 of the seat assembly 19 in the width direction of the vehicle frame 11. With such a setting, the volume of the first space 1206a and the second space 1207a can be increased, which is conducive to arranging a storage box assembly 1205 with a larger volume in the first space 1206a and / or the second space 1207a, and further conducive to increasing the storage volume of the storage box assembly 1205.

[0070] As an embodiment, the storage box assembly 1205 includes an upper box body 1205a and a lower box body 1205b, and the upper box body 1205a is fixedly connected to the lower box body 1205b. Specifically, the upper box body 1205a is provided with a storage opening 1205c. With such a setting, items can be stored and retrieved in the storage box assembly 1205 through the storage opening 1205c. More specifically, both the upper box body 1205a and the lower box body 1205b are at least partially located in the first space 1206a and / or the second space 1207a. When observing from the height direction of the vehicle frame 11, the storage opening 1205c does not overlap with the first space 1206a, and the storage opening 1205c does not overlap with the second space 1207a. With such a setting, it is possible to avoid interference of the first covering side cover 1206 at the first space 1206a and the second covering side cover 1207 at the second space 1207a when taking items from the storage opening 1205c, which is beneficial to improving the convenience of use of the storage box assembly 1205.

[0071] In addition, the storage box assembly 1205 is split into an upper box body 1205a and a lower box body 1205b, so that the storage spaces can be processed inside the upper box body 1205a and the lower box body 1205b respectively, thereby avoiding the situation that a large-volume storage space cannot be processed inside the storage box assembly 1205 due to the integral structure of the storage box assembly 1205. Through the above settings, while simplifying the processing technology of the storage space inside the storage box assembly 1205, the volume of the storage space inside the storage box assembly 1205 can also be increased.

[0072] As Figure 9 shown, as an optional implementation manner, the lower box body 1205b is provided with a first through hole 1205d and a second through hole 1205e, and the first through hole 1205d and the second through hole 1205e are located at the front part of the lower box body 1205b. The first through hole 1205d is used to fix the cigarette lighter, and the second through hole 1205e is used to fix the USB connector.

[0073] As Figure 9 and Figure 10 shown, as an implementation manner, the storage box assembly 1205 includes a storage cover 1205f, the storage cover 1205f is rotatably connected to the upper box body 1205a, and the storage cover 1205f is configured to be able to cover the storage opening 1205c. With such a setting, the storage opening 1205c can be blocked by the storage cover 1205f. During the driving of the all-terrain vehicle 100, the items inside the storage box assembly 1205 can be prevented from falling out of the storage opening 1205c, which is beneficial to improving the storage safety of the storage box assembly 1205.

[0074] Specifically, one side of the storage cover 1205f has a rotating shaft 1205g and an extension part 1205h. Among them, the extension part 1205h is basically in a "U" shape, and the rotating shaft 1205g is located at one end of the extension part 1205h away from the storage cover 1205f, and the rotating shaft 1205g is rotatably connected to the upper box body 1205a. With such a setting, the rotation and opening / closing of the storage cover 1205f are realized through the rotating shaft 1205g. In addition, the "U"-shaped extension part 1205h can prevent the extension part 1205h from interfering with other components during the rotation of the storage cover 1205f, so that the storage cover 1205f can be opened and closed normally.

[0075] More specifically, one side of the storage cover 1205f away from the extension portion 1205h is provided with a cover body connection portion 1205i. At least part of the lower box body 1205b extends upward to form a fixing boss 1205j. The fixing boss 1205j is located at the rear of the lower box body 1205b. The cover body connection portion 1205i can pass through the fixing boss 1205j and be snap-connected to the fixing boss 1205j. With such a setting, it is beneficial for the storage cover 1205f and the upper box body 1205a to open and close, thereby facilitating the use of the storage box assembly 1205.

[0076] As an alternative implementation, a limiting portion 1205k is provided on the extension portion 1205h. The limiting portion 1205k is configured to limit the rotation angle of the storage cover 1205f relative to the upper box body 1205a, so as to avoid interference between the storage cover 1205f and other components on the all-terrain vehicle 100 due to excessive rotation angle of the storage cover 1205f.

[0077] Specifically, when the storage cover 1205f covers the storage opening 1205c, both sides of the storage cover 1205f along the width direction of the vehicle frame 11 can respectively fit against the first covering side cover 1206 and the second covering side cover 1207 (refer to Figure 8 ). With such a setting, the flatness of the storage cover 1205f with the first covering side cover 1206 and the second covering side cover 1207 can be improved, thereby improving the driving comfort of the vehicle frame 11. In addition, it is also beneficial to reduce the wind resistance at the storage cover 1205f, thereby reducing the wind resistance of the all-terrain vehicle 100 and further reducing the energy consumption of the all-terrain vehicle 100.

[0078] As Figure 9 shown, as an implementation, at least part of the storage box assembly 1205 is located in the first space 1206a. The all-terrain vehicle 100 further includes a shifting assembly 18. At least part of the shifting assembly 18 is located in the second space 1207a. The shifting assembly 18 is connected to the second covering side cover 1207. With such a setting, interference between the storage box assembly 1205 and the shifting assembly 18 can be avoided, and it is also beneficial to improve the space utilization rate of the first space 1206a and the second space 1207a, thereby improving the structural compactness in the first space 1206a and the second space 1207a. Specifically, the shifting assembly 18 is configured as an electronic shifter 181. The electronic shifter 181 can improve the shifting response speed, thereby improving the handling performance of the all-terrain vehicle 100.

[0079] As an alternative implementation, the shift component 18 is snap-connected to the second covering side cover 1207 and fixedly connected by fasteners. With this arrangement, the installation stability of the shift component 18 in the second space 1207a can be improved. Moreover, the shift component 18 is fixedly connected to the storage box component 1205. With this arrangement, the installation stability of the shift component 18 in the second space 1207a can be further improved.

[0080] Specifically, at least a part of one side of the storage box component 1205 close to the second covering side cover 1207 is formed with an installation post 1205m upward. A fastener passes through the shift component 18 and is fixedly connected to the installation post 1205m. In some embodiments, at least a part of one side of the upper box body 1205a close to the second covering side cover 1207 is formed with an installation post 1205m upward. The installation post 1205m is a boss post, and the fastener is a screw. With this arrangement, the screw passes through the shift component 18 and is threadedly connected to the boss post, thereby realizing the fixed connection between the shift component 18 and the upper box body 1205a to improve the connection stability between the shift component 18 and the upper box body 1205a.

[0081] As Figure 9 shown, as an implementation manner, mounting bosses 1205n are provided on both sides of the storage box component 1205 along the width direction of the vehicle frame 11. Moreover, snap structures 1205p are provided on one side of the first covering side cover 1206 close to the storage box component 1205 and on one side of the second covering side cover 1207 close to the storage box component 1205. The snap structures 1205p pass through the mounting bosses 1205n and are snap-connected to the mounting bosses 1205n. With this arrangement, the snap connection method can simplify the assembly process of the storage box component 1205 with the first covering side cover 1206 and the second covering side cover 1207, thereby improving the assembly efficiency of the storage box component 1205.

[0082] In this embodiment, the snap structure 1205p is a type-A snap. With this arrangement, the type-A snap can be disassembled and assembled by hand, which can further simplify the assembly process of the storage box component 1205 with the first covering side cover 1206 and the second covering side cover 1207 and improve the assembly efficiency of the storage box component 1205.

[0083] In some embodiments, mounting bosses 1205n are provided on both sides of the lower box body 1205b along the width direction of the vehicle frame 11. In this embodiment, the lower box body 1205b bears the weight of the items. The lower box body 1205b is connected to the first covering side cover 1206 and the second covering side cover 1207 through the mounting bosses 1205n, so that the overall installation stability of the storage box component 1205 can be improved.

[0084] As an implementation manner, box mounting holes 1205s are further provided on both sides of the storage box assembly 1205 in the width direction of the vehicle frame 11. Side cover mounting holes 1209 are provided on the side of the first covering side cover 1206 close to the storage box assembly 1205 and on the side of the second covering side cover 1207 close to the storage box assembly 1205. A fastener is passed through the box mounting hole 1205s and the side cover mounting hole 1209 to fix the storage box assembly 1205, the first covering side cover 1206, and the second covering side cover 1207. In some embodiments, the above-mentioned fastener can be a bolt, and the use of the fastener can further improve the connection stability between the storage box assembly 1205 and the first covering side cover 1206 and the second covering side cover 1207.

[0085] In some embodiments, box mounting holes 1205s are provided on both sides of the upper box body 1205a in the width direction of the vehicle frame 11. In the height direction of the vehicle frame 11, the side cover mounting holes 1209 are located at the upper parts of the first covering side cover 1206 and the second covering side cover 1207. With such a setting, the box mounting holes 1205s and the side cover mounting holes 1209 can both be located above the lower box body 1205b, so as to avoid interference of the lower box body 1205b with the assembly of the box mounting holes 1205s and the side cover mounting holes 1209, which is beneficial to improving the assembly convenience of the storage box assembly 1205, the first covering side cover 1206, and the second covering side cover 1207.

[0086] As Figure 9 and Figure 11 shown, as an implementation manner, the storage box assembly 1205 is provided with a front fixing portion 1205q and a rear fixing portion 1205r. The front fixing portion 1205q is fixedly connected to the front fender 126, and the rear fixing portion 1205r is fixedly connected to the vehicle frame 11. With such a setting, the connection stability of the storage box assembly 1205 in the all-terrain vehicle 100 can be further improved, so that the storage box assembly 1205 can store heavier items, thereby improving the storage function of the storage box assembly 1205.

[0087] In some embodiments, the lower box body 1205b is provided with a front fixing portion 1205q and a rear fixing portion 1205r, and the fixing portion is fixedly connected to the front fender 126 (refer to Figure 8 ) by screws, and the rear fixing portion 1205r is fixedly connected to the vehicle frame 11 by screws. In this implementation manner, the lower box body 1205b bears the weight of the items. Connecting the lower box body 1205b to the front fender 126 and the vehicle frame 11 can improve the load-bearing capacity of the lower box body 1205b, so that heavier items can be stored in the storage box assembly 1205, thereby improving the storage effect of the storage box assembly 1205.

[0088] As Figure 12 , Figure 13 andFigure 15 As shown, as an implementation manner, the body covering 12 further includes a radiator grille 12f and a covering side cover 12g. Among them, the covering side cover 12g is supported by the frame 11. The covering side cover 12g serves as an exterior part of the all-terrain vehicle 100 and is used to protect the components inside the all-terrain vehicle 100. Specifically, along the length direction of the frame 11, the covering side cover 12g is at least partially located between the front fender 126 and the seat assembly 19. The radiator grille 12f is installed at the front end of the covering side cover 12g. The covering side cover 12g at least partially surrounds and forms an air intake passage 12ga. The radiator grille 12f is communicated with the air intake passage 12ga. The air intake passage 12ga has at least one air inlet (not shown in the figure) and one air outlet (not shown in the figure). The opening of the air inlet faces the radiator grille 12f, and the air outlet faces the power assembly 15. When observing along the length direction of the frame 11, at least part of the radiator grille 12f can be observed in the front view; the outermost side of the air intake passage 12ga is closer to the longitudinal center plane 10s than the outermost side of the left steering handle 2013 or the right steering handle 2014. With such a setting, during the driving of the all-terrain vehicle 100, air can enter the air intake passage 12ga through the radiator grille 12f and flow through the air outlet towards the power assembly 15, which is beneficial to improving the heat dissipation effect of the power assembly 15, so that the power assembly 15 can work stably. Secondly, by dissipating heat from the power assembly 15, it is beneficial to reduce the overall temperature of the all-terrain vehicle 100, which is beneficial to improving the body feeling temperature of the driver and passengers, and further improving the comfort of the driver and passengers. In addition, through the above setting, it is beneficial to avoid damage to the power assembly 15 caused by too high temperature of the power assembly 15, thus being beneficial to improving the service life of the power assembly 15.

[0089] More specifically, at least part of the radiator grille 12f is located above the upper surface of the front fender 126, so that the front fender 126 does not hinder the air intake of the radiator grille 12f, thereby improving the heat dissipation effect of the power assembly 15.

[0090] In this embodiment, the minimum distance between the heat dissipation grille 12f and the rotation axis of the front wheel 132 in the height direction of the all-terrain vehicle 100 is the first distance H1. Define a reference plane 101 that passes through the lowermost end of the front wheel 132 and is perpendicular to the height direction of the frame 11. The minimum distance between the rotation axis of the front wheel 132 and the reference plane 101 in the height direction of the frame 11 is the second distance H2. Among them, the ratio range of the first distance H1 to the second distance H2 is 1.5 to 2.4. Specifically, the ratio range of the first distance H1 to the second distance H2 is 1.7 to 2.2. More specifically, the ratio of the first distance H1 to the second distance H2 is 1.95. Through the above settings, it is possible to avoid the front fender 126 blocking the heat dissipation grille 12f due to the too small first distance H1, thereby improving the air intake efficiency of the heat dissipation grille 12f; it is also possible to avoid the heat dissipation grille 12f being located below the front fender 126 due to the too small first distance H1, thereby preventing the front wheel 132 below the front fender 126 from splashing mud and other impurities into the heat dissipation grille 12f, so as to avoid the damage of the power assembly 15 caused by the impact of impurities, and further improve the service life of the power assembly 15 while improving the heat dissipation effect of the power assembly 15. In addition, the above settings can also avoid increasing the volume in the height direction of the frame 11 due to the too high first distance H1, thereby improving the structural compactness of the all-terrain vehicle 100; at the same time, it can also avoid the interference between the heat dissipation grille 12f and the steering system 20 due to the too high first distance H1, so as to improve the working stability of the heat dissipation grille 12f and the steering system 20.

[0091] As an embodiment, at least a part of the power assembly 15 is located below the seat assembly 19, and at least a part of the air outlet is located below the air intake passage 12ga, so that the air outlet can face the power assembly 15. Among them, the seat assembly 19 is connected to the covering side cover 12g, and the seat assembly 19 is configured to be able to seal the rear of the air intake passage 12ga, so that the air in the air intake passage 12ga is conveyed to the power assembly 15 from the air outlet below the air intake passage 12ga. With such a setting, it is possible to avoid the leakage of the gas in the air intake passage 12ga from the rear, which is beneficial to improving the sealing performance of the air intake passage 12ga, and further beneficial to improving the heat dissipation effect on the power assembly 15. In addition, by sealing the air intake passage 12ga through the seat assembly 19, there is no need to add additional components to seal the air intake passage 12ga, which is beneficial to simplifying the structure of the air intake passage 12ga and reducing the production cost of the all-terrain vehicle 100.

[0092] As an implementation manner, the covering side cover 12g is provided with a mounting hole 12gc, and the mounting hole 12gc is located at the front end of the covering side cover 12g. At least part of the heat dissipation grille 12f is located in the mounting hole 12gc and fixedly connected to the covering side cover 12g. With such a setting, the mounting hole 12gc can be arranged facing forward, so that during the driving of the all-terrain vehicle 100, it is beneficial for air to enter the intake passage 12ga through the mounting hole 12gc, and further beneficial for improving the heat dissipation effect on the power assembly 15. In some embodiments, the heat dissipation grille 12f and the covering side cover 12g are connected by screws, which is beneficial for improving the connection stability between the heat dissipation grille 12f and the covering side cover 12g.

[0093] As an implementation manner, the covering side cover 12g includes a first covering side cover 12gd and a second covering side cover 12ge. Both the first covering side cover 12gd and the second covering side cover 12ge are supported by the vehicle frame 11, and the first covering side cover 12gd and the second covering side cover 12ge are distributed along the width direction of the vehicle frame 11. Specifically, the heat dissipation grille 12f is installed at the front end of the first covering side cover 12gd and / or the second covering side cover 12ge. Among them, the first covering side cover 12gd surrounds and forms a first space, and the second covering side cover 12ge surrounds and forms a second space. At least part of the intake passage 12ga is located in the first space and / or the second space. The heat dissipation grille 12f communicates with the first space and / or the second space. With such a setting, the intake passage 12ga can flexibly adjust the layout position according to the assembly requirements, so as to avoid the intake passage 12ga interfering with the assembly of other components. When the intake passage 12ga is located in the first space and the second space, it can avoid insufficient air intake caused by unilateral air intake of the intake passage 12ga, which is beneficial for increasing the air intake of the intake passage 12ga, and further beneficial for improving the heat dissipation effect on the power assembly 15. Through the above settings, the intake passage 12ga can flexibly adjust the layout position according to the assembly requirements and the heat dissipation requirements of the power assembly 15, which is beneficial for improving the assembly flexibility of the intake passage 12ga.

[0094] As an alternative implementation manner, the heat dissipation grille 12f is provided with a plurality of heat dissipation baffles 12fa, and heat dissipation holes 12fb are formed between two adjacent heat dissipation baffles 12fa. With such a setting, the heat dissipation baffles 12fa can prevent flying stones and gravel from entering the intake passage 12ga through the mounting hole 12gc, thereby preventing flying stones and gravel from damaging the power assembly 15, and further beneficial for improving the protection of the internal components of the all-terrain vehicle 100.

[0095] In this implementation manner, at least part of the heat dissipation holes 12fb are arranged higher than the upper surface of the front fender 126. With such a setting, it can prevent the front fender 126 from blocking the air from entering the intake passage 12ga through the heat dissipation holes 12fb, which is beneficial for improving the air intake efficiency of the heat dissipation holes 12fb.

[0096] As an implementation, the body covering includes an instrument mounting cover 1204 for mounting the instrument panel, and the instrument mounting cover 1204 is mounted on the front fender 126. The radiator grille 12f is located on at least one side of the instrument mounting cover 1204 in the width direction of the vehicle frame 11. With such a setting, it can be avoided that the instrument mounting cover 1204 obstructs the air from entering the intake passage 12ga from the radiator grille 12f, which is beneficial to improving the intake efficiency of the cooling holes 12fb.

[0097] As an implementation, the body covering further includes a storage box assembly 1205 for storing items, and the storage box assembly 1205 is supported by the vehicle frame 11. Specifically, the storage box assembly 1205 is at least partially located in the first space and / or the second space. More specifically, the storage box assembly 1205 includes a storage lid 1205f, and both sides of the storage lid 1205f in the width direction of the vehicle frame 11 can respectively fit against the first covering side cover 12gd and the second covering side cover 12ge, so that the storage lid 1205f can seal the upper part of the intake passage 12ga. With such a setting, the intake passage 12ga can be a substantially sealed space, thereby avoiding the leakage of air inside and outside the intake passage 12ga, so that the air can be delivered to the power assembly 15 after passing through the intake passage 12ga, which is beneficial to improving the heat dissipation efficiency of the power assembly 15.

[0098] As Figure 14 and Figure 15 shown, as a realization, the steering system 20 includes a steering handle 201 for controlling the steering of the all-terrain vehicle 100. The steering handle 201 includes a left steering handle 2013 and a right steering handle 2014, and the left steering handle 2013 and the right steering handle 2014 are distributed in the width direction of the vehicle frame 11, which is beneficial to the driver's operation of the steering handle 201.

[0099] Among them, the body covering 12 includes two mounting plates 12ja, and the two mounting plates 12ja are arranged under the front fender 126 and are respectively located on the left and right sides of the steering handle 201. The two mounting plates 12ja and the front fender 126 surround to form a left storage space and a right storage space with the openings facing the rear of the all-terrain vehicle 100. Observed along the height direction of the vehicle frame 11, the left storage space and the right storage space are respectively located under the left steering handle 2013 and the right steering handle 2014, and the left storage space and the right storage space respectively overlap at least partially with the left steering handle 2013 and the right steering handle 2014, so as to provide a storage function for the driver and / or passengers, and the positions of the left storage space and the right storage space are beneficial for the driver to store items.

[0100] Specifically, the body covering 12 further includes two storage covers 12jb which are respectively connected to the left storage space and the right storage space and can close the left storage space and the right storage space;

[0101] The upper end of the storage cover 12jb is snap-connected to the mounting plate 12ja, and the lower end of the storage cover 12jb is rotatably connected to the mounting plate 12ja.

[0102] As an implementation manner, when there is one mounting plate 12ja, the intake passage 12ga is at least partially located between the mounting plate 12ja and the longitudinal center plane 10s. When observing along the height direction of the vehicle frame 11, the mounting plate 12ja is at least partially located below the left steering handle 2013 and / or below the right steering handle 2014, and the mounting plate 12ja at least partially overlaps with the left steering handle 2013 and / or the right steering handle 2014;

[0103] As an implementation manner, when there are two mounting plates 12ja and the two mounting plates 12ja are respectively at least partially located below the left steering handle 2013 and below the right steering handle 2014, the intake passage 12ga is at least partially located between the two mounting plates 12ja, so that the intake passage 12ga will not interfere with the two mounting plates 12ja; and the air in the intake passage 12ga will not leak from the two mounting plates 12ja, so as to improve the heat dissipation effect of the power assembly 15.

[0104] It should be understood that for those of ordinary skill in the art, improvements or changes can be made according to the above description, and all such improvements and changes should fall within the protection scope of the appended claims of this application.
