[0030] In order to make the personnel in the art better understand the scheme of the present application, the technical scheme in the specific embodiment of the present application will be described clearly and completely below in combination with the drawings in the embodiment of the present application.

[0031] As shown in Figure 1 and Figure 2 , the present application provides an all-terrain vehicle 100, which comprises a frame 11, a vehicle body covering 12, a walking system 13, a suspension system 14, a power assembly 15, a transmission assembly 16, a fuel assembly 17, a seat assembly 19 and an electrical assembly 22.

[0032] In order to clearly illustrate the technical scheme of the present application, the front, rear, left, right, upper and lower directions are defined as shown in Figure 1 In the present application, the length direction of the frame 11 refers to the front-rear direction in Figure 1 , the width direction of the frame 11 refers to the left-right direction in Figure 1 , and the height direction of the frame 11 refers to the up-down direction in Figure 1 .

[0033] The vehicle frame 11 serves as a basic frame of the all-terrain vehicle 100, and is configured to support the vehicle 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, and the electrical assembly 22. The vehicle body cover 12 is at least partially arranged on the vehicle frame 11 and connected to the vehicle frame 11, so that the vehicle body cover 12 can protect the components inside the all-terrain vehicle 100. The running system 13 is at least partially arranged below the vehicle frame 11, and the suspension system 14 connects the running system 13 to the vehicle frame 11. The power assembly 15 is in driving connection with the running system 13, and specifically, the transmission assembly 16 drives the power assembly 15 to the running system 13. The fuel assembly 17 includes a fuel tank 171, which is configured to supply power to the power assembly 15, and specifically, the fuel tank 171 is configured to deliver fuel to the power assembly 15. The electrical assembly 22 is supported by the vehicle frame 11, and the electrical assembly 22 is supported by the vehicle body cover 12 or the vehicle frame 11, and the electrical assembly 22 is configured to display the driving data of the all-terrain vehicle 100, control the operation of the all-terrain vehicle, and the like. The seat assembly 19 is supported by the vehicle frame 11, and the seat assembly 19 is configured to support the driver and / or the passenger.

[0034] As shown in Figure 3 and Figure 4 As an implementation manner, the power assembly 15 includes a continuously variable transmission mechanism 152 and an engine 151. The engine 151 is in driving connection with the continuously variable transmission mechanism 152, and the continuously variable transmission mechanism 152 is in driving connection with the running system 13, so as to drive the running system 13 to drive the all-terrain vehicle 100 to run. The heat dissipation assembly 25 includes a heat dissipation duct 253, which is configured to guide the air outside the all-terrain vehicle 100 to the continuously variable transmission mechanism 152, so as to cool and dissipate heat of the continuously variable transmission mechanism 152.

[0035] Specifically, the heat dissipation duct 253 includes an air inlet 2531 and an air outlet 2532. The heat dissipation duct 253 is configured to deliver the external air to the continuously variable transmission mechanism 152 through the air inlet 2531 and the air outlet 2532. The vehicle body cover 12 includes a front fender 126, which is configured to block mud, gravel, and the like. The air inlet 2531 is arranged 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 entering the heat dissipation duct 253 from the air inlet 2531 is discharged from the air outlet 2532 and reaches the continuously variable transmission mechanism 152.

[0036] Since a large amount of heat is generated in the operation of the continuously variable transmission mechanism 152, and the continuously variable transmission mechanism 152 is overheated, and the cooling effect of the continuously variable transmission mechanism 152 by the existing cooling structure is insufficient, the heat dissipation pipeline 253 is additionally provided to improve the cooling effect of the continuously variable transmission mechanism 152. After the external air is transported to the continuously variable transmission mechanism 152 through the heat dissipation pipeline 253, the heat of the continuously variable transmission mechanism 152 is taken away, thereby improving the cooling effect of the continuously variable transmission mechanism 152, and reducing the temperature of the whole terrain vehicle 100.

[0037] As an implementation manner, the opening of the air inlet 2531 is basically arranged forward. Since the airflow from front to back is generated around the whole terrain vehicle 100 during driving, the opening of the air inlet 2531 is basically arranged forward, so that the external air can smoothly enter the heat dissipation pipeline 253 from the air inlet 2531, and form an airflow in the heat dissipation pipeline 253 from the air inlet 2531 to the air outlet 2532, thereby improving the cooling effect of the continuously variable transmission mechanism 152.

[0038] In the present application, a filtering structure is arranged in the air inlet 2531, which is used to block the sand, gravel and the like from entering the heat dissipation pipeline 253, thereby avoiding the sand, gravel and the like from entering the continuously variable transmission mechanism 152 to cause collision and abrasion of the continuously variable transmission mechanism 152, and further preventing damage of the continuously variable transmission mechanism 152. In the present application, the filtering structure is a filter screen or the like.

[0039] As an implementation manner, the whole terrain vehicle 100 comprises a cargo box assembly 21, the cargo box assembly 21 comprises a cargo box 211 and a front cargo box mounting plate 212, and 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, and the air inlet 2531 is located in the gap 254. The above arrangement makes the external air enter the air inlet 2531 from 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 in the gap 254 to block most of the sand, gravel and the like from entering the heat dissipation pipeline 253, thereby avoiding the sand, gravel and the like from entering the continuously variable transmission mechanism 152 to cause collision and abrasion of the continuously variable transmission mechanism 152, and further preventing damage of the continuously variable transmission mechanism 152. At the same time, the air inlet 2531 is arranged in the gap 254, so that the external air can enter the air inlet 2531 through the gap 254, thereby not affecting the air intake effect of the heat dissipation pipeline 253. In addition, the above arrangement can also make the air inlet 2531 arranged by using the gap 254, so as to make the structure of the whole terrain vehicle 100 more compact, and improve the space utilization of the whole terrain vehicle 100.

[0040] As an implementation, the power assembly 15 further comprises a variable intake pipe 153. The variable intake pipe 153 is in communication with the continuously variable transmission mechanism 152, and the variable intake pipe 153 is used to intake air into the continuously variable transmission mechanism 152. From the width direction of the vehicle frame 11, the variable intake pipe 153 at least partially overlaps the heat dissipation pipe 253 to avoid interference between the variable intake pipe 153 and the heat dissipation pipe 253, and to improve the compactness of the internal structure of the all-terrain vehicle 100.

[0041] Specifically, the all-terrain vehicle 100 further comprises a fuel assembly 17. The fuel assembly 17 comprises a fuel tank 171 and a fuel filler 172, which is in communication with the fuel tank 171 and is located above the fuel tank 171. Along the width direction of the vehicle frame 11, the heat dissipation pipe 253 is at least partially located between the fuel filler 172 and the variable intake pipe 153. The heat dissipation pipe 253 is arranged between the fuel filler 172 and the variable intake pipe 153 to avoid interference between the heat dissipation pipe 253, the fuel filler 172 and the variable intake pipe 153, and to improve the compactness of the internal structure of the all-terrain vehicle 100.

[0042] More specifically, the heat dissipation pipe 253 is at least partially bent to form a bent portion 2533a configured to avoid the fuel filler 172. The arrangement of the bent portion 2533a avoids interference between the heat dissipation pipe 253 and the fuel filler 172, and further improves the compactness of the internal structure of the all-terrain vehicle 100.

[0043] More specifically, the bent portion 2533a is fixedly connected to the vehicle frame 11, and the fixed connection between the bent portion 2533a and the vehicle frame 11 can be welding or bolting, etc., to improve the stability of the heat dissipation pipe 253 during driving of the all-terrain vehicle 100.

[0044] As an implementation, the heat dissipation pipe 253 comprises an integrally formed round pipe portion 2533 and a flat pipe portion 2534, the round pipe portion 2533 is in communication with the air inlet 2531, the flat pipe portion 2534 is in communication with the air outlet 2532, and the flat pipe portion 2534 is configured to reduce the thickness of the heat dissipation pipe 253 in a predetermined direction. The predetermined direction can be in any direction, and the arrangement of the flat pipe portion 2534 allows the heat dissipation pipe 253 to pass through the narrow gap between the internal structures of the all-terrain vehicle 100 to avoid interference with the internal structures of the all-terrain vehicle 100, thereby making full use of the limited space to improve the space utilization of the interior of the all-terrain vehicle 100.

[0045] It should be noted that the bent portion 2533a is located on the round pipe portion 2533 so that the internal passage at the bent portion 2533a is not too narrow, thereby reducing the flow resistance of air in the heat dissipation pipe 253, and further improving the heat dissipation effect on the continuously variable transmission mechanism 152.

[0046] Specifically, along the width direction of the vehicle frame 11, the flat tube part 2534 is at least partially located between the variable speed intake pipe 153 and the vehicle frame 11, and the thickness of the flat tube part 2534 along the width direction of the vehicle frame 11 is smaller than the thickness of the flat tube part 2534 along the height direction of the vehicle frame 11. The gap between the variable speed intake pipe 153 and the vehicle frame 11 is small, and the arrangement of the flat tube part 2534 enables the heat dissipation pipe 253 to pass through the gap between the variable speed intake pipe 153 and the vehicle frame 11, and the heat dissipation pipe 253 does not interfere with the variable speed intake pipe 153 and the vehicle frame 11, thereby making full use of the limited space to improve the space utilization rate inside the all-terrain vehicle 100.

[0047] More specifically, the flat tube part 2534 is fixedly connected with the vehicle frame 11, and the fixed connection between the flat tube part 2534 and the vehicle frame 11 can be welding or bolt connection, etc., further improving the stability of the heat dissipation pipe 253 during driving of the all-terrain vehicle 100.

[0048] As shown in Figure 5 , Figure 6 and Figure 7 , as an implementation manner, the vehicle body cover 12 includes a lower guard plate 12h, which is located below the vehicle frame 11 and is fixedly connected with the vehicle frame 11, so that the lower guard plate 12h can protect the lower part of the all-terrain vehicle 100 to avoid damage to the internal parts of the all-terrain vehicle 100 caused by external stones, mud and other impurities. Among them, the lower guard plate 12h is at least partially located below the power assembly 15, and the lower guard plate 12h extends along a predetermined plane perpendicular to the height direction of the vehicle frame 11, so that the lower guard plate 12h does not affect the installation of the power assembly 15, and further improves the protection of the power assembly 15.

[0049] The lower guard plate 12h is provided with a heat dissipation hole 12ha, which is arranged towards the power assembly 15 and at least partially overlaps the power assembly 15 as viewed from the height direction of the vehicle frame 11, so that during driving of the all-terrain vehicle 100, external air can be delivered to the upper side of the lower guard plate 12h through the heat dissipation hole 12ha, so that the external air can be delivered to the power assembly 15, thereby improving the heat dissipation effect of the power assembly 15.

[0050] Specifically, the lower guard plate 12h is provided with a heat dissipation groove 12hb, an opening of the heat dissipation groove 12hb is arranged downward, the heat dissipation groove 12hb has a front side wall 12hc which is substantially convex, the front side wall 12hc includes a front end 12hr and a rear end 12hs, a height of the rear end 12hs is higher than a height of the front end 12hr, the front end 12hr is located at the opening of the heat dissipation groove 12hb, the rear end 12hs is connected with a groove bottom of the heat dissipation groove 12hb, and the groove bottom of the heat dissipation groove 12hb is provided with a heat dissipation hole 12ha. The above arrangement can make the external air be transported from the front end 12hr of the front side wall 12hc to the rear end 12hs of the front side wall 12hc along the front side wall 12hc, and then be transported from the rear end 12hs of the front side wall 12hc to the power assembly 15 through the heat dissipation hole 12ha in the groove bottom of the heat dissipation groove 12hb, so as to realize heat dissipation of the power assembly 15. The convex front side wall 12hc can have a guiding effect on the external air, so as to increase the air intake amount of the air entering the heat dissipation hole 12ha, and further improve the heat dissipation effect of the power assembly 15.

[0051] A preset straight line 12hd connecting the front end 12hr and the rear end 12hs, a longitudinal plane 109 perpendicular to the width direction of the vehicle frame 11, and a reference plane 102 perpendicular to the height direction of the vehicle frame 11 are defined, a normal projection of the reference plane 102 on the longitudinal plane 109 is a horizontal line, a normal projection of the preset straight line 12hd on the longitudinal plane 109 is a side wall connecting line, an acute angle σ between the side wall connecting line and the horizontal line ranges from 23° to 40°, and an opening of the acute angle is arranged rearward. Specifically, the acute angle σ between the side wall connecting line and the horizontal line ranges from 26° to 36°. More specifically, the acute angle σ between the side wall connecting line and the horizontal line is 33°.

[0052] Through the above arrangement, the acute angle σ between the side wall connecting line and the horizontal line can be prevented from being too small to cause the length of the front side wall 12hc along the length direction of the vehicle frame 11 to be too long, so as to prevent the front side wall 12hc from being too long to reduce the structural strength of the lower guard plate 12h, and to prevent the front side wall 12hc from being too long to cause air leakage to the outside, thereby improving the heat dissipation effect of the heat dissipation hole 12ha on the power assembly 15. Meanwhile, the above arrangement can also prevent the acute angle σ between the side wall connecting line and the horizontal line from being too large to cause the thickness of the lower guard plate 12h along the height direction of the vehicle frame 11 to be too large, so as to prevent the lower guard plate 12h from interfering with the internal components of the ATV 100.

[0053] As an implementation manner, the heat dissipation groove 12hb has a first side wall 12he and a second side wall 12hf distributed along the width direction of the vehicle frame 11, and the first side wall 12he, the second side wall 12hf and the front side wall 12hc surround a gas inlet channel 12hg configured to be capable of conveying external air into the heat dissipation hole 12ha. The above arrangement can enable the external air to be limited in the gas inlet channel 12hg to avoid the external air from leaking out, thereby improving the air intake amount at the heat dissipation hole 12ha and further improving the heat dissipation effect on the power assembly 15.

[0054] Specifically, the heat dissipation groove 12hb has a rear side wall 12hj for sealing the rear of the gas inlet channel 12hg, and the rear side wall 12hj is configured to block the external air from leaking in and out of the gas inlet channel 12hg. At the same time, the above arrangement can also enable the external air to be blocked by the rear side wall 12hj so that the external air can flow into the heat dissipation hole 12ha.

[0055] In the present application, the groove bottom of the heat dissipation groove 12hb is provided with a grid structure 12hk, and the gaps between the grid structures 12hk form the heat dissipation holes 12ha. The grid structure 12hk is used to block the external impurities such as stones and mud from entering above the lower guard plate 12h, thereby avoiding damage to the power assembly 15 and the like caused by external impurities.

[0056] As an alternative implementation manner, 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, and the first guard plate 12hm and the second guard plate 12hn are both provided with the heat dissipation groove 12hb and the heat dissipation hole 12ha. Among them, the split lower guard plate 12h can be adjusted according to the assembly requirements, thereby facilitating the assembly of the lower guard plate 12h.

[0057] 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 towards the engine 151, and the heat dissipation holes 12ha of the second guard plate 12hn are arranged towards the continuously variable transmission mechanism 152, so that the heat dissipation holes 12ha on the first guard plate 12hm can dissipate heat for the engine 151, and the heat dissipation holes 12ha on the second guard plate 12hn can dissipate heat for the continuously variable transmission mechanism 152.

[0058] In the present 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, and the heat dissipation holes 12ha on the plurality of first heat dissipation grooves 12hp are all arranged towards the engine 151 to improve the heat dissipation efficiency of the engine 151.

[0059] In this embodiment, the continuously variable transmission (CVT) 152 and the engine 151 are distributed along the width direction of the frame 11. The heat dissipation slot 12hb includes a second heat dissipation slot 12hq. At least one second heat dissipation slot 12hq is provided on the second guard plate 12hn. When viewed from the height direction of the frame 11, the heat dissipation holes 12ha on the second heat dissipation slot 12hq at least partially overlap with the CVT 152, thereby allowing the second heat dissipation slot 12hq to better deliver outside air to the CVT 152 through the heat dissipation holes 12ha, thereby improving the heat dissipation efficiency of the CVT 152.

[0060] like Figure 8 and Figure 9 As shown, in one embodiment, the vehicle body panel 12 further includes a storage box assembly 1205, a first side cover 1206, and a second side cover 1207. Specifically, the storage box assembly 1205, the first side cover 1206, and the second side cover 1207 are all at least partially supported by the frame 11. Along the length of the frame 11, the storage box assembly 1205, the first side cover 1206, and the second side cover 1207 are all at least partially located between the front fender 126 and the seat assembly 19. The first side cover 1206 and the second side cover 1207 are distributed on both sides of the storage box assembly 1205 along the width of the frame 11. The first side cover 1206 at least partially surrounds a first space 1206a, and the second side cover 1207 at least partially surrounds a second space 1207a. With this configuration, the first space 1206a and the second space 1207a can provide space for the arrangement of components, thereby improving the space utilization rate of the first cover side cover 1206 and the second cover side cover 1207.

[0061] In this application, along the width direction of the frame 11, the heat dissipation pipe 253 (refer to...) Figure 3 It is located on one side of the storage box assembly 1205.

[0062] More specifically, the storage box assembly 1205 is at least partially located within the first space 1206a and / or the second space 1207a. This arrangement allows the storage box assembly 1205 to utilize the arrangement 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 thus increasing its storage capacity, which in turn enhances the storage function of the all-terrain vehicle 100.

[0063] In the embodiment, the volume of the storage box assembly 1205 ranges from 6L to 10L. Specifically, the volume of the storage box assembly 1205 ranges from 7L to 9L. More specifically, the volume of the storage box assembly 1205 is 8L. Through the above setting, it can be avoided that the volume of the storage box assembly 1205 is too large to interfere with other components in the first space 1206a and the second space 1207a, thereby facilitating to improve the space utilization in the first space 1206a and the second space 1207a; it can also be avoided that the volume of the storage box assembly 1205 is too small to reduce the space capable of storing objects in the storage box assembly 1205, thereby improving the storage performance of the storage box assembly 1205.

[0064] As shown in Figure 8 , as an embodiment, the power assembly 15 further includes an air filter mechanism (not shown), a continuously variable transmission (CVT) (refer to Figure 3 ), an air filter intake pipe 155, and a 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 with the air filter mechanism, and the air filter intake pipe 155 is used to deliver air to the air filter mechanism. The continuously variable transmission is used to adjust the transmission ratio, the transmission intake pipe 153 is connected with the continuously variable transmission, and the transmission intake pipe 153 is used to provide gas for the continuously variable transmission. Specifically, 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 transmission intake pipe 153. In this way, the compactness of the structure at the storage box assembly 1205 can be improved.

[0065] In the embodiment, the air filter intake pipe 155 and the transmission intake pipe 153 are both at least partially located below the storage box assembly 1205. In this way, it can be avoided that the air filter intake pipe 155 and the transmission intake pipe 153 interfere with the taking of objects from the storage box assembly 1205, thereby facilitating to improve the convenience of use of the storage box assembly 1205.

[0066] As shown in Figure 8 and Figure 9 , as an embodiment, the maximum distance D8 of the first covering side cover 1206 and the second covering side cover 1207 along the width direction of the vehicle frame 11 is greater than the maximum width W1 of the seat assembly 19 along the width direction of the vehicle frame 11. In this way, the volume of the first space 1206a and the second space 1207a can be increased, thereby facilitating to arrange a larger volume of the storage box assembly 1205 in the first space 1206a and / or the second space 1207a, and thereby facilitating to increase the storage volume of the storage box assembly 1205.

[0067] As an implementation, 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 with the lower box body 1205b. Specifically, the upper box body 1205a is provided with a storage opening 1205c. In this way, the storage opening 1205c can be used to access the items in the storage box assembly 1205. More specifically, the upper box body 1205a and the lower box body 1205b are both at least partially located in the first space 1206a and / or the second space 1207a. From the height direction of the vehicle frame 11, the storage opening 1205c does not overlap the first space 1206a, and the storage opening 1205c does not overlap the second space 1207a. In this way, the first covering side cover 1206 at the first space 1206a and the second covering side cover 1207 at the second space 1207a can be prevented from interfering with the retrieval of items from the storage opening 1205c, thereby facilitating improved convenience of use of the storage box assembly 1205.

[0068] In addition, the storage box assembly 1205 is split into the upper box body 1205a and the lower box body 1205b, so that the interior of the upper box body 1205a and the interior of the lower box body 1205b can be respectively processed to form storage spaces, thereby avoiding the inability to process large-volume storage spaces inside the storage box assembly 1205 due to the one-piece structure of the storage box assembly 1205. Through the above arrangement, the processing technology of the storage space inside the storage box assembly 1205 can be simplified, and the volume of the storage space inside the storage box assembly 1205 can be increased.

[0069] As shown in Figure 9 As an optional implementation, 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 of the lower box body 1205b. The first through hole 1205d is used to fix a cigarette lighter, and the second through hole 1205e is used to fix a USB connector.

[0070] As shown in Figure 9 and Figure 10 As an implementation, the storage box assembly 1205 includes a storage cover 1205f, the storage cover 1205f is rotationally connected with the upper box body 1205a, and the storage cover 1205f is configured to cover the storage opening 1205c. In this way, the storage cover 1205f can shield the storage opening 1205c, and during the driving of the ATV 100, the items inside the storage box assembly 1205 can be prevented from falling out of the storage opening 1205c, thereby facilitating improved storage safety of the storage box assembly 1205.

[0071] Specifically, one side of the storage cover 1205f is provided with a rotating shaft 1205g and an extension 1205h. The extension 1205h is substantially in the shape of "U", and the rotating shaft 1205g is located at one end of the extension 1205h away from the storage cover 1205f, and the rotating shaft 1205g is rotationally connected with the upper box body 1205a. In this way, the rotating shaft 1205g is used to realize the rotation of the storage cover 1205f. In addition, the "U"-shaped extension 1205h can avoid the interference between the extension 1205h and other components during the rotation of the storage cover 1205f, so that the storage cover 1205f can be normally opened and closed.

[0072] More specifically, the side of the storage cover 1205f away from the extension 1205h is provided with a cover connecting portion 1205i, and the lower box body 1205b is at least partially extended upward to form a fixing boss 1205j, which is located at the rear of the lower box body 1205b. The cover connecting portion 1205i can be arranged in the fixing boss 1205j and clamped with the fixing boss 1205j. In this way, the opening and closing between the storage cover 1205f and the upper box body 1205a can be facilitated, thereby improving the convenience of use of the storage box assembly 1205.

[0073] As an optional implementation manner, the extension 1205h is provided with a limiting portion 1205k, which is configured to limit the rotation angle of the storage cover 1205f relative to the upper box body 1205a, so as to avoid the interference between the storage cover 1205f and other components on the all-terrain vehicle 100 due to the too large rotation angle of the storage cover 1205f.

[0074] Specifically, when the storage cover 1205f covers the storage port 1205c, the two sides of the storage cover 1205f along the width direction of the vehicle frame 11 can be respectively attached to the first covering side cover 1206 and the second covering side cover 1207 (refer to Figure 8 ). In this way, the flatness of the storage cover 1205f, the first covering side cover 1206 and the second covering side cover 1207 can be improved, thereby improving the driving comfort of the all-terrain vehicle 100. In addition, it is also beneficial to reduce the wind resistance at the storage cover 1205f, so as to reduce the wind resistance of the all-terrain vehicle 100, and further reduce the energy consumption of the all-terrain vehicle 100.

[0075] As Figure 9As shown, in one embodiment, the storage box assembly 1205 is at least partially located within the first space 1206a. The all-terrain vehicle 100 also includes a shift assembly 18, which is at least partially located within the second space 1207a and connected to the second cover side cover 1207. This arrangement avoids interference between the storage box assembly 1205 and the shift assembly 18, and also improves the space utilization of the first space 1206a and the second space 1207a, thereby improving the structural compactness within the first space 1206a and the second space 1207a. Specifically, the shift assembly 18 is configured as an electronic shifter 181. The electronic shifter 181 can improve the shift response speed, thereby improving the handling performance of the all-terrain vehicle 100.

[0076] As an optional implementation, the shift assembly 18 is snapped into the second cover side cover 1207 and fixedly connected by fasteners. This configuration improves the installation stability of the shift assembly 18 within the second space 1207a. Furthermore, the shift assembly 18 is fixedly connected to the storage box assembly 1205. This configuration further improves the installation stability of the shift assembly 18 within the second space 1207a.

[0077] Specifically, the storage box assembly 1205 has at least a partially upward-facing mounting post 1205m on the side near the second cover side cover 1207, and a fastener passes through the shift assembly 18 and is fixedly connected to the mounting post 1205m. In some embodiments, the upper housing 1205a has at least a partially upward-facing mounting post 1205m on the side near the second cover side cover 1207. The mounting post 1205m is a boss post, and the fastener is a screw. With this configuration, the shift assembly 18 is fixedly connected to the upper housing 1205a by screws passing through it and threadedly connected to the boss post, thereby improving the connection stability between the shift assembly 18 and the upper housing 1205a.

[0078] like Figure 9 As shown, in one embodiment, the storage compartment assembly 1205 has mounting bosses 1205n on both sides along the width direction of the frame 11. Furthermore, both the first cover side cover 1206 and the second cover side cover 1207 near the storage compartment assembly 1205 are provided with snap-fit ​​structures 1205p, which pass through the mounting bosses 1205n and engage with them. This snap-fit ​​connection simplifies the assembly process of the storage compartment assembly 1205 with the first cover side cover 1206 and the second cover side cover 1207, thereby improving the assembly efficiency of the storage compartment assembly 1205.

[0079] In the embodiment, the buckle structure 1205p is an A-type buckle. In this way, the A-type buckle can be disassembled manually, thereby further simplifying the assembly process of the storage box assembly 1205 and the first and second covering side covers 1206 and 1207 and improving the assembly efficiency of the storage box assembly 1205.

[0080] In some embodiments, the lower box body 1205b is provided with mounting bosses 1205n on both sides in the width direction of the vehicle frame 11. In the embodiment, the lower box body 1205b bears the weight of the articles, and the lower box body 1205b is connected to the first and second covering side covers 1206 and 1207 through the mounting bosses 1205n, thereby improving the mounting stability of the entire storage box assembly 1205.

[0081] As an embodiment, the storage box assembly 1205 is further provided with box body mounting holes 1205s on both sides in the width direction of the vehicle frame 11, the first covering side cover 1206 is provided with side cover mounting holes 1209 on the side close to the storage box assembly 1205, and the second covering side cover 1207 is provided with side cover mounting holes 1209 on the side close to the storage box assembly 1205, a fastener is arranged in the box body mounting holes 1205s and the side cover mounting holes 1209 to fix the storage box assembly 1205, the first and second covering side covers 1206 and 1207. In some embodiments, the fastener can be a bolt, and the connection stability of the storage box assembly 1205 and the first and second covering side covers 1206 and 1207 can be further improved through the fastener.

[0082] In some embodiments, the upper box body 1205a is provided with box body mounting holes 1205s on both sides 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 portions of the first and second covering side covers 1206 and 1207. In this way, the box body mounting holes 1205s and the side cover mounting holes 1209 are both located above the lower box body 1205b, thereby avoiding interference of the lower box body 1205b with the assembly of the box body mounting holes 1205s and the side cover mounting holes 1209, and facilitating the assembly convenience of the storage box assembly 1205 and the first and second covering side covers 1206 and 1207.

[0083] As shown in FIGS. 12 and 13, as an embodiment, 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 with the front fender 126, and the rear fixing portion 1205r is fixedly connected with the vehicle frame 11. In this way, the connection stability of the storage box assembly 1205 in the ATV 100 can be further improved, so that the storage box assembly 1205 can store articles with a larger weight, thereby improving the storage function of the storage box assembly 1205. Figure 9 and Figure 11 As an embodiment, 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 with the front fender 126, and the rear fixing portion 1205r is fixedly connected with the vehicle frame 11. In this way, the connection stability of the storage box assembly 1205 in the ATV 100 can be further improved, so that the storage box assembly 1205 can store articles with a larger weight, thereby improving the storage function of the storage box assembly 1205.

[0084] In some embodiments, the lower box 1205b is provided with a front fixing part 1205q and a rear fixing part 1205r, and the fixing parts are fixedly connected with the front fender 126 (refer to Figure 8 ) through screws, and the rear fixing part 1205r is fixedly connected with the frame 11 through screws. In the present embodiment, the lower box 1205b bears the weight of the articles, and connecting the lower box 1205b with the front fender 126 and the frame 11 can improve the load-bearing capacity of the lower box 1205b, so that articles with greater weight can be stored in the storage box assembly 1205, thereby improving the storage effect of the storage box assembly 1205.

[0085] As shown in Figure 12 and Figure 13 , as an embodiment, the vehicle body cover 12 further comprises a heat dissipation grille 12f and a cover side cover 12g. The cover side cover 12g is supported by the frame 11, and the cover side cover 12g serves as an appearance part of the all-terrain vehicle 100 for protecting the internal components of the all-terrain vehicle 100. Specifically, along the length direction of the frame 11, the cover side cover 12g is at least partially located between the front fender 126 and the seat assembly 19, the heat dissipation grille 12f is mounted at the front end of the cover side cover 12g, the cover side cover 12g at least partially surrounds a heat dissipation space 12ga, the heat dissipation grille 12f is in communication with the heat dissipation space 12ga, and the heat dissipation space 12ga has at least one opening (not shown in the figure) facing the power assembly 15. In this way, during the driving of the all-terrain vehicle 100, air can enter the heat dissipation space 12ga through the heat dissipation grille 12f and flow towards the power assembly 15 through the opening, thereby improving the heat dissipation effect of the power assembly 15 and enabling the power assembly 15 to work stably. In addition, by dissipating heat from the power assembly 15, the overall temperature of the all-terrain vehicle 100 can be reduced, thereby improving the body temperature of the driver and passengers and improving the comfort of the driver and passengers. Furthermore, by the above arrangement, it is possible to avoid damage to the power assembly 15 caused by excessively high temperature of the power assembly 15, thereby improving the service life of the power assembly 15.

[0086] As an implementation, the power assembly 15 is at least partially located below the seat assembly 19, and the opening is at least partially located below the heat dissipation space 12ga, so that the opening is capable of facing the power assembly 15. The seat assembly 19 is connected with the cover side cover 12g, and the seat assembly 19 is configured to seal the rear of the heat dissipation space 12ga, so that the air in the heat dissipation space 12ga is transported to the power assembly 15 from the opening below the heat dissipation space 12ga. In this way, the gas in the heat dissipation space 12ga can be prevented from leaking from the rear, thereby improving the sealing of the heat dissipation space 12ga, and further improving the heat dissipation effect of the power assembly 15. In addition, the seat assembly 19 seals the heat dissipation space 12ga, so that additional components are not required to seal the heat dissipation space 12ga, thereby simplifying the structure of the heat dissipation space 12ga and reducing the production cost of the all-terrain vehicle 100.

[0087] As an implementation, the cover side cover 12g is provided with a mounting hole 12gc, and the mounting hole 12gc is located at the front end of the cover side cover 12g. The heat dissipation grille 12f is at least partially located in the mounting hole 12gc and is fixedly connected with the cover side cover 12g. In this way, the mounting hole 12gc is arranged to face the front, so that during the driving of the all-terrain vehicle 100, the air is beneficial to enter the heat dissipation space 12ga through the mounting hole 12gc, thereby improving the heat dissipation effect of the power assembly 15. In some embodiments, the heat dissipation grille 12f is connected with the cover side cover 12g by screws, thereby improving the connection stability of the heat dissipation grille 12f and the cover side cover 12g.

[0088] As an implementation, the covering side cover 12g includes a first covering side cover 12gd and a second covering side cover 12ge, both of which are supported by the vehicle frame 11 and 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. The heat dissipation space 12ga includes a first space formed by the first covering side cover 12gd and a second space formed by the second covering side cover 12ge. More specifically, both the first space and the second space have at least one opening. In this way, when the heat dissipation space 12ga includes the first space or the second space, the heat dissipation space 12ga can be flexibly adjusted in layout according to assembly requirements, thereby avoiding interference with the assembly of other components. When the heat dissipation space 12ga includes both the first space and the second space, it can avoid insufficient air intake caused by one-sided air intake of the heat dissipation space 12ga, thereby facilitating improvement of the air intake of the heat dissipation space 12ga, and further facilitating improvement of the heat dissipation effect on the power assembly 15. Through the above arrangement, the heat dissipation space 12ga can be flexibly adjusted in layout according to assembly requirements and the heat dissipation requirements of the power assembly 15, thereby facilitating improvement of the assembly flexibility of the heat dissipation space 12ga.

[0089] As an optional implementation, the heat dissipation grille 12f is provided with a plurality of heat dissipation baffles 12fa, and a heat dissipation hole 12fb is formed between adjacent two heat dissipation baffles 12fa. In this way, the heat dissipation baffle 12fa can prevent flying stones and gravel from entering the heat dissipation space 12ga from the mounting hole 12gc, thereby preventing damage to the power assembly 15 caused by flying stones and gravel, and further facilitating improvement of the protection of the internal components of the all-terrain vehicle 100.

[0090] In the present embodiment, at least part of the heat dissipation holes 12fb are arranged higher than the upper surface of the front mudguard 126. In this way, the front mudguard 126 can be prevented from hindering air from entering the heat dissipation space 12ga from the heat dissipation holes 12fb, thereby facilitating improvement of the air intake efficiency of the heat dissipation holes 12fb.

[0091] As an implementation, the vehicle body covering member includes an instrument mounting cover 1204 for mounting an instrument panel, and the instrument mounting cover 1204 is mounted on the front mudguard 126, and the heat dissipation grille 12f is located on at least one side of the instrument mounting cover 1204 along the width direction of the vehicle frame 11. In this way, the instrument mounting cover 1204 can be prevented from hindering air from entering the heat dissipation space 12ga from the heat dissipation grille 12f, thereby facilitating improvement of the air intake efficiency of the heat dissipation holes 12fb.

[0092] As an implementation, the vehicle body cover further comprises a storage box assembly 1205 for storing articles, 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 heat dissipation space 12ga. More specifically, the storage box assembly 1205 comprises a storage cover 1205f, which can be respectively attached to the first covering side cover 12gd and the second covering side cover 12ge along the two sides of the vehicle frame 11 in the width direction, so that the storage cover 1205f can seal the heat dissipation space 12ga. In this way, the heat dissipation space 12ga can be a substantially sealed space, thereby avoiding air leakage in and out of the heat dissipation space 12ga, so that the air can be transported to the power assembly 15 after passing through the heat dissipation space 12ga, thereby facilitating to improve the heat dissipation efficiency of the power assembly 15.
