Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an all-terrain vehicle. Background Technology

[0002] An all-terrain vehicle is a multi-functional vehicle designed specifically for various complex terrains. It possesses strong off-road capabilities and stability, enabling it to easily navigate challenging environments such as mud, sand, snow, and rocks.

[0003] All-terrain vehicles typically include a frame, body panels, running gear, suspension system, powertrain, and electrical components. The powertrain comprises an engine and a continuously variable transmission (CVT), with the CVT regulating the engine's output power. Both the engine and CVT generate significant heat during operation; if this heat cannot be dissipated effectively, it can cause damage to both components. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide an all-terrain vehicle with a powertrain that has better heat dissipation.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] An all-terrain vehicle includes a frame, body panels, a running gear system, and a powertrain. The body panels are supported by the frame. The running gear system is at least partially located below the frame. A suspension system connects the running gear system to the frame. The powertrain is supported by the frame. The body panels include a lower guard plate located below and fixedly connected to the frame. The lower guard plate extends substantially along a predetermined plane perpendicular to the height of the frame. The lower guard plate is at least partially located below the powertrain. The lower guard plate has ventilation holes facing the powertrain, and when viewed from the height of the frame, the ventilation holes at least partially overlap with the powertrain.

[0007] Furthermore, the lower guard plate has a heat dissipation groove with the opening facing downward. The heat dissipation groove has a front sidewall that is basically convex and curved. The front sidewall includes a front end and a rear end. The height of the rear end is higher than that of the front end. The front end is located at the opening of the heat dissipation groove, and the rear end is connected to the bottom of the heat dissipation groove. The bottom of the heat dissipation groove has heat dissipation holes.

[0008] Furthermore, a preset straight line connecting the front and rear ends, a longitudinal plane perpendicular to the width direction of the frame, and a reference plane perpendicular to the height direction of the frame are defined. The orthographic projection of the reference plane onto the longitudinal plane is a horizontal line, and the orthographic projection of the preset straight line onto the longitudinal plane is a side wall line. The angle between the side wall line and the horizontal line is in the range of 23° to 40°, and the opening of the angle is set to face rearward.

[0009] Furthermore, the heat dissipation slot has a first sidewall and a second sidewall distributed along the width direction of the frame, and the first sidewall, the second sidewall and the front sidewall surround to form an air intake channel, which is configured to deliver outside air to the heat dissipation hole.

[0010] Furthermore, the heat sink has a rear sidewall for sealing the rear of the air intake channel, the rear sidewall being configured to prevent outside air from leaking out of the air intake channel.

[0011] Furthermore, the bottom of the heat dissipation groove is provided with a grid structure, and the gaps between the grid structures form heat dissipation holes.

[0012] Furthermore, the lower guard plate includes a first guard plate and a second guard plate located behind the first guard plate. The second guard plate is at least partially located below the powertrain. Both the first guard plate and the second guard plate are provided with heat dissipation grooves and heat dissipation holes.

[0013] Furthermore, the powertrain includes a continuously variable transmission (CVT) and an engine, with the cooling vents of the first skid plate facing the engine and the cooling vents of the second skid plate facing the CVT.

[0014] Furthermore, the heat dissipation slot includes a first heat dissipation slot, and the first protective plate includes multiple first heat dissipation slots. The multiple first heat dissipation slots are distributed along the width direction of the vehicle frame, and the heat dissipation holes on the multiple first heat dissipation slots are all oriented towards the engine.

[0015] Furthermore, the continuously variable transmission (CVT) mechanism and the engine are distributed along the width direction of the vehicle frame, and the heat dissipation slots include a second heat dissipation slot. At least one second heat dissipation slot is provided on the second skid plate. When viewed from the height direction of the vehicle frame, the heat dissipation holes on the second heat dissipation slots at least partially overlap with the CVT mechanism.

[0016] The aforementioned all-terrain vehicle can have heat dissipation holes on the lower guard plate, with the holes facing the powertrain. When viewed from the height of the vehicle frame, the heat dissipation holes and the powertrain at least partially overlap. This allows external air to be delivered to the upper part of the lower guard plate through the heat dissipation holes during the operation of the all-terrain vehicle, so that external air can be delivered to the powertrain, thereby improving the heat dissipation effect of the powertrain.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, this application provides an all-terrain vehicle 100, which includes a frame 11, a body panel 12, a running system 13, a suspension system 14, a powertrain 15, a transmission assembly 16, a fuel assembly 17, a seat assembly 19, and an electrical assembly 22.

[0032] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1The directions shown are front, rear, left, right, top, and bottom. In this application, the length direction of the frame 11 refers to... Figure 1 In the fore-and-aft direction, the width direction of the frame 11 refers to... Figure 1 The left and right directions in the middle, and the height direction of frame 11 refers to Figure 1 The up and down directions in the middle.

[0033] The frame 11 serves as the basic framework of the all-terrain vehicle 100, supporting the body panel 12, running gear 13, suspension system 14, powertrain 15, transmission assembly 16, fuel system 17, seat assembly 19, and electrical assembly 22. The body panel 12 is at least partially located on and connected to the frame 11, protecting the internal components of the all-terrain vehicle 100. The running gear 13 is at least partially located below the frame 11, and the suspension system 14 connects the running gear 13 to the frame 11. The powertrain 15 is drive-connected to the running gear 13; specifically, the transmission assembly 16 drives the powertrain 15 to the running gear 13. The fuel system 17 includes a fuel tank 171 for powering the powertrain 15; specifically, the fuel tank 171 supplies fuel to the powertrain 15. The electrical component 22 is supported by the frame 11, and is also supported by the body panel 12 or the frame 11. The electrical component 22 is used to display the driving data of the all-terrain vehicle 100 and control the operation of the all-terrain vehicle. The seat assembly 19 is supported by the frame 11 and is used to support the driver and / or passengers.

[0034] like Figure 3 and Figure 4 As shown, in one implementation, the powertrain 15 includes a continuously variable transmission (CVT) 152 and an engine 151. The engine 151 is driven by the CVT 152, which is driven by the running gear 13, thereby driving the running gear 13 to move the all-terrain vehicle 100. The cooling assembly 25 includes a cooling duct 253, which directs air from outside the all-terrain vehicle 100 to the CVT 152, thereby cooling the CVT 152.

[0035] Specifically, the cooling duct 253 includes an air inlet 2531 and an air outlet 2532. The cooling duct 253 is configured to deliver external air to the continuously variable transmission (CVT) 152 through the air inlet 2531 and the air outlet 2532. The body panel 12 includes a front fender 126, which is used to block mud, sand, gravel, etc. The air inlet 2531 is mounted on the front fender 126, and external air enters the cooling duct 253 through the air inlet 2531. The air outlet 2532 is oriented towards the CVT 152, and the air entering the cooling duct 253 from the air inlet 2531 is discharged from the air outlet 2532, reaching the CVT 152.

[0036] Because the continuously variable transmission (CVT) 152 generates a large amount of heat during operation, its temperature becomes excessively high. The existing cooling structure is insufficient to effectively cool the CVT 152. Therefore, a cooling pipe 253 is added to improve the cooling effect. External air is supplied to the CVT 152 through the cooling pipe 253, carrying away the heat and thus improving the cooling efficiency, thereby reducing the overall temperature of the all-terrain vehicle 100.

[0037] As one implementation method, the opening of the air intake 2531 is basically facing forward. Since the all-terrain vehicle 100 generates airflow from front to back when it is driving, the opening of the air intake 2531 is basically facing forward, which allows external air to smoothly enter the heat dissipation duct 253 from the air intake 2531 and form an airflow from the air intake 2531 to the air outlet 2532 in the heat dissipation duct 253, thereby improving the cooling effect of the continuously variable transmission mechanism 152.

[0038] In this application, a filter structure is provided inside the air inlet 2531. The filter structure is used to prevent mud, sand, gravel, etc. from entering the heat dissipation pipe 253, thereby preventing mud, sand, gravel, etc. from entering the continuously variable transmission (CVT) mechanism 152 and causing collision and wear to the CVT mechanism 152, thus preventing damage to the CVT mechanism 152. In this application, the filter structure is a filter screen or the like.

[0039] In one implementation, the all-terrain vehicle 100 includes a cargo box assembly 21, which includes a cargo box 211 and a front cargo box mounting plate 212 for mounting the cargo box 211. A front fender 126 has a mounting surface 1261, and the front cargo box mounting plate 212 is mounted on the mounting surface 1261 with a gap 254 between it and the mounting surface 1261. An air inlet 2531 is located within the gap 254. This arrangement allows 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. By placing the air inlet 2531 within the gap 254, most of the mud, sand, and gravel are blocked from entering the cooling duct 253, thus preventing mud, sand, and gravel from entering the continuously variable transmission (CVT) 152 and causing collisions and wear, thereby preventing damage to the CVT 152. Meanwhile, by placing the air intake 2531 within the gap 254, external air can enter the air intake 2531 through the gap 254, thus not affecting the air intake effect of the heat dissipation pipe 253. In addition, the above arrangement also allows the air intake 2531 to be arranged using the gap 254, making the structure of the all-terrain vehicle 100 more compact and improving the space utilization of the all-terrain vehicle 100.

[0040] As one implementation, the powertrain 15 also includes a transmission intake manifold 153. The transmission intake manifold 153 connects to a continuously variable transmission (CVT) 152 and is used to supply air to the CVT 152. Viewed from the width direction of the frame 11, the transmission intake manifold 153 at least partially overlaps with the cooling duct 253 to avoid interference between them and to improve the compactness of the internal structure of the all-terrain vehicle 100.

[0041] Specifically, the all-terrain vehicle 100 also includes a fuel assembly 17. The fuel assembly 17 includes a fuel tank 171 and a filler neck 172, the filler neck 172 communicating with and located above the fuel tank 171. Along the width of the frame 11, a cooling duct 253 is at least partially located between the filler neck 172 and the transmission intake pipe 153. The cooling duct 253 is interposed between the filler neck 172 and the transmission intake pipe 153 to avoid interference between the cooling duct 253, the filler neck 172, and the transmission intake pipe 153, and to improve the compactness of the internal structure of the all-terrain vehicle 100.

[0042] More specifically, the cooling duct 253 is at least partially bent to form a bend 2533a, which is configured to avoid the filler neck 172. The bend 2533a prevents the cooling duct 253 from interfering with the filler neck 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 frame 11. The fixed connection between the bent portion 2533a and the frame 11 can be welding or bolting, etc., to improve the stability of the heat dissipation pipe 253 during the operation of the all-terrain vehicle 100.

[0044] As one implementation, the heat dissipation duct 253 includes an integrally formed circular tube portion 2533 and a flat tube portion 2534. The circular tube portion 2533 is connected to the air inlet 2531, and the flat tube portion 2534 is connected to the air outlet 2532. The flat tube portion 2534 is configured to reduce the thickness of the heat dissipation duct 253 along a preset direction. The preset direction can be any direction. The arrangement of the flat tube portion 2534 allows the heat dissipation duct 253 to pass through narrow gaps between the internal structures of the all-terrain vehicle 100, avoiding interference with the internal structure 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.

[0045] It should be noted that the bend 2533a is located on the round tube 2533 so that the internal channel at the bend 2533a is not too narrow, thereby reducing the airflow resistance in the heat dissipation pipe 253 and improving the heat dissipation effect on the continuously variable transmission mechanism 152.

[0046] Specifically, along the width direction of the frame 11, the flat tube portion 2534 is at least partially located between the transmission intake pipe 153 and the frame 11. The thickness of the flat tube portion 2534 along the width direction of the frame 11 is less than the thickness of the flat tube portion 2534 along the height direction of the frame 11. The gap between the transmission intake pipe 153 and the frame 11 is small. The arrangement of the flat tube portion 2534 allows the heat dissipation pipe 253 to pass through the gap between the transmission intake pipe 153 and the frame 11 without interfering with the transmission intake pipe 153 and the frame 11. This makes full use of the limited space and improves the space utilization rate inside the all-terrain vehicle 100.

[0047] More specifically, the flat tube section 2534 is fixedly connected to the frame 11. The fixed connection between the flat tube section 2534 and the frame 11 can be welding or bolting, which further improves the stability of the heat dissipation pipe 253 during the operation of the all-terrain vehicle 100.

[0048] like Figure 5 , Figure 6 and Figure 7As shown, in one implementation, the body panel 12 includes a lower guard plate 12h, which is located below and fixedly connected to the frame 11. This allows the lower guard plate 12h to protect the lower part of the all-terrain vehicle 100 from damage to internal components caused by external debris such as stones and mud. The lower guard plate 12h is at least partially located below the powertrain 15, and extends substantially along a predetermined plane perpendicular to the height of the frame 11. This ensures that the lower guard plate 12h does not interfere with the installation of the powertrain 15, while further enhancing the protection of the powertrain 15.

[0049] The lower guard plate 12h has a heat dissipation hole 12ha, which is positioned facing the powertrain 15. When viewed from the height of the frame 11, the heat dissipation hole 12ha and the powertrain 15 overlap at least partially. Thus, during the operation of the all-terrain vehicle 100, external air can be transported to the top of the lower guard plate 12h through the heat dissipation hole 12ha, so that external air can be transported to the powertrain 15, thereby improving the heat dissipation effect of the powertrain 15.

[0050] Specifically, the lower guard plate 12h has a heat dissipation groove 12hb with its opening facing downwards. The heat dissipation groove 12hb has a front sidewall 12hc that is generally convex. The front sidewall 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 has a heat dissipation hole 12ha. This arrangement allows external air to be transported from the front end 12hr of the front sidewall 12hc along the front sidewall 12hc to the rear end 12hs of the front sidewall 12hc, and then from the rear end 12hs of the front sidewall 12hc through the heat dissipation hole 12ha at the bottom of the heat dissipation groove 12hb to the powertrain 15, thereby achieving heat dissipation for the powertrain 15. The convex curved front sidewall 12hc can guide external air, thereby increasing the air intake into the heat dissipation hole 12ha, and further improving the heat dissipation effect of the powertrain 15.

[0051] Define 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 frame 11, and a reference plane 102 perpendicular to the height direction of the frame 11. The orthographic projection of the reference plane 102 onto the longitudinal plane 109 is a horizontal line. The orthographic projection of the preset straight line 12hd onto the longitudinal plane 109 is a side wall line. The angle σ between the side wall line and the horizontal line ranges from 23° to 40°, with the opening of the angle facing rearward. Specifically, the angle σ between the side wall line and the horizontal line ranges from 26° to 36°. More specifically, the angle σ between the side wall line and the horizontal line is 33°.

[0052] The above design avoids an excessively small angle σ between the sidewall line and the horizontal line, which would result in an excessively long front sidewall 12hc along the length of the frame 11. This prevents the front sidewall 12hc from becoming too long, thus reducing the structural strength of the lower skid plate 12h and preventing air leakage to the outside. This also improves the heat dissipation effect of the cooling vents 12ha on the powertrain 15. Furthermore, the above design also avoids an excessively large angle σ between the sidewall line and the horizontal line, which would result in an excessively thick lower skid plate 12h along the height of the frame 11. This prevents the lower skid plate 12h from interfering with the internal components of the all-terrain vehicle 100.

[0053] In one implementation, the heat dissipation slot 12hb has a first sidewall 12he and a second sidewall 12hf distributed along the width direction of the frame 11. The first sidewall 12he, the second sidewall 12hf, and the front sidewall 12hc surround and form an air intake channel 12hg, which is configured to deliver outside air to the heat dissipation hole 12ha. This arrangement allows outside air to be confined within the air intake channel 12hg to prevent air leakage, thereby increasing the air intake at the heat dissipation hole 12ha and improving the heat dissipation effect on the powertrain 15.

[0054] Specifically, the heat sink 12hb has a rear sidewall 12hj for sealing the rear of the air intake channel 12hg. The rear sidewall 12hj is configured to prevent outside air from leaking out of the air intake channel 12hg. At the same time, the above arrangement also allows outside air to be blocked by the rear sidewall 12hj, so that outside air can flow into the heat dissipation hole 12ha.

[0055] In this application, a grille structure 12hk is provided at the bottom of the heat dissipation slot 12hb, and heat dissipation holes 12ha are formed by the gaps between the grille structures 12hk. The grille structure 12hk is used to block external impurities such as stones and mud from entering above the lower guard plate 12h, thereby preventing external impurities from damaging the powertrain 15 and the like.

[0056] 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 powertrain 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. The separate lower guard plate 12h can be adjusted according to assembly requirements, thus facilitating its assembly.

[0057] Specifically, the powertrain 15 includes a continuously variable transmission (CVT) 152 and an engine 151. The heat dissipation holes 12ha on the first guard plate 12hm face the engine 151, and the heat dissipation holes 12ha on the second guard plate 12hn face the CVT 152. This allows the heat dissipation holes 12ha on the first guard plate 12hm to dissipate heat from the engine 151, and the heat dissipation holes 12ha on the second guard plate 12hn to dissipate heat from the CVT 152.

[0058] In this embodiment, the heat sink 12hb includes a first heat sink 12hp, and the first protective plate 12hm includes a plurality of first heat sinks 12hp. The plurality of first heat sinks 12hp are distributed along the width direction of the frame 11, and the heat dissipation holes 12ha on the plurality of first heat sinks 12hp are all arranged facing 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 9As shown, in one embodiment, the body panel 12 further includes 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 direction 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 direction 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] 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.

[0062] In this embodiment, 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. This configuration avoids the storage box assembly 1205 having an excessively large volume, which could interfere with other components in the first space 1206a and the second space 1207a, thus improving space utilization in both spaces. It also avoids the storage box assembly 1205 having an excessively small volume, which could reduce the storage space available for the storage box assembly 1205, thereby improving its storage performance.

[0063] like Figure 8 As shown, in one embodiment, the powertrain 15 also includes an air filter mechanism (not shown) and a continuously variable transmission (CVT) mechanism (see reference). Figure 3The system includes an air filter intake pipe 155 and a transmission intake pipe 153. The air filter mechanism removes particulate impurities from the air. The air filter intake pipe 155 is connected to the air filter mechanism and supplies air to it. The continuously variable transmission (CVT) mechanism adjusts the transmission ratio. The transmission intake pipe 153 is connected to the CVT mechanism and supplies air to it. Specifically, viewed from the height of the 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. This arrangement improves the structural compactness of the storage box assembly 1205.

[0064] In this embodiment, both the air filter inlet pipe 155 and the variable speed inlet pipe 153 are at least partially located below the storage box assembly 1205. This arrangement avoids interference from the air filter inlet pipe 155 and the variable speed inlet pipe 153 in retrieving items from the storage box assembly 1205, thereby improving the ease of use of the storage box assembly 1205.

[0065] like Figure 8 and Figure 9 As shown, in one embodiment, the maximum distance D8 between the first side cover 1206 and the second side cover 1207 along the width direction of the frame 11 is greater than the maximum width W1 of the seat assembly 19 along the width direction of the frame 11. This arrangement increases the volume of the first space 1206a and the second space 1207a, thereby facilitating the placement of a larger storage box assembly 1205 within the first space 1206a and / or the second space 1207a, and consequently increasing the storage capacity of the storage box assembly 1205.

[0066] In one embodiment, the storage box assembly 1205 includes an upper box 1205a and a lower box 1205b, which are fixedly connected. Specifically, the upper box 1205a has a storage opening 1205c. This arrangement allows items to be stored and retrieved within the storage box assembly 1205 through the storage opening 1205c. More specifically, both the upper box 1205a and the lower box 1205b are at least partially located within a first space 1206a and / or a second space 1207a. Viewed from the height of the 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. This configuration avoids interference between the first covering side cover 1206 at the first space 1206a and the second covering side cover 1207 at the second space 1207a and the item being retrieved from the storage opening 1205c, thereby improving the ease of use of the storage box assembly 1205.

[0067] Furthermore, the storage box assembly 1205 is split into an upper box 1205a and a lower box 1205b, allowing storage spaces to be fabricated separately inside the upper box 1205a and the lower box 1205b. This avoids the limitation of fabricating large storage spaces inside the storage box assembly 1205 due to its one-piece structure. This design simplifies the fabrication process of the storage space inside the storage box assembly 1205 while also increasing its volume.

[0068] like Figure 9 As shown, as an optional implementation, the lower housing 1205b has a first through hole 1205d and a second through hole 1205e, which are located at the front of the lower housing 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.

[0069] like Figure 9 and Figure 10 As shown, in one embodiment, the storage box assembly 1205 includes a storage cover 1205f, which is rotatably connected to the upper box body 1205a. The storage cover 1205f is configured to cover the storage opening 1205c. This configuration allows the storage opening 1205c to be covered by the storage cover 1205f, preventing items inside the storage box assembly 1205 from falling out of the storage opening 1205c during the movement of the all-terrain vehicle 100, thereby improving the storage security of the storage box assembly 1205.

[0070] Specifically, the storage cover 1205f has a rotating shaft 1205g and an extension 1205h on one side. The extension 1205h is essentially U-shaped, and the rotating shaft 1205g is located at the end of the extension 1205h furthest from the storage cover 1205f. The rotating shaft 1205g is rotatably connected to the upper housing 1205a. This arrangement allows the storage cover 1205f to rotate and open / close via the rotating shaft 1205g. Furthermore, the U-shaped extension 1205h prevents interference with other components during rotation, ensuring the storage cover 1205f can open and close normally.

[0071] More specifically, the storage cover 1205f has a cover connecting portion 1205i on the side away from the extension 1205h, and the lower housing 1205b extends upward at least partially to form a fixing boss 1205j. The fixing boss 1205j is located at the rear of the lower housing 1205b, and the cover connecting portion 1205i can pass through the fixing boss 1205j and engage with it. This arrangement facilitates the opening and closing of the storage cover 1205f and the upper housing 1205a, thereby improving the ease of use of the storage box assembly 1205.

[0072] As an optional implementation, the extension 1205h is provided with a limiting part 1205k, which is configured to limit the rotation angle of the storage cover 1205f relative to the upper housing 1205a, thereby preventing the storage cover 1205f from rotating too much and causing interference between the storage cover 1205f and other components on the all-terrain vehicle 100.

[0073] Specifically, when the storage cover 1205f covers the storage opening 1205c, the storage cover 1205f can respectively fit the first cover side cover 1206 and the second cover side cover 1207 on both sides along the width direction of the frame 11 (refer to...). Figure 8 This design improves the flatness of the storage cover 1205f, the first side cover 1206, and the second side cover 1207, thereby enhancing the driving comfort of the all-terrain vehicle 100. Furthermore, it helps reduce wind resistance at the storage cover 1205f, thus reducing the overall wind resistance of the all-terrain vehicle 100 and consequently lowering its energy consumption.

[0074] like Figure 9 As 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] In this embodiment, the snap-fit ​​structure 1205p is an A-type snap-fit. With this configuration, the A-type snap-fit ​​can be disassembled and assembled by hand, thereby further simplifying the assembly process of the storage box assembly 1205 with the first cover side cover 1206 and the second cover side cover 1207, and improving the assembly efficiency of the storage box assembly 1205.

[0079] In some embodiments, mounting bosses 1205n are provided on both sides of the lower housing 1205b along the width direction of the frame 11. In this embodiment, the lower housing 1205b bears the weight of the items. By connecting the lower housing 1205b to the first cover side cover 1206 and the second cover side cover 1207 through the mounting bosses 1205n, the overall installation stability of the storage box assembly 1205 can be improved.

[0080] In one embodiment, the storage box assembly 1205 is provided with box mounting holes 1205s on both sides along the width direction of the frame 11. The first cover side cover 1206 near the storage box assembly 1205 and the second cover side cover 1207 near the storage box assembly 1205 are both provided with side cover mounting holes 1209. A fastener passes through the box mounting holes 1205s and the side cover mounting holes 1209 to fix the storage box assembly 1205, the first cover side cover 1206, and the second cover side cover 1207. In some embodiments, the fastener can be a bolt, which can further improve the connection stability between the storage box assembly 1205 and the first cover side cover 1206 and the second cover side cover 1207.

[0081] In some embodiments, the upper housing 1205a has housing mounting holes 1205s on both sides along the width direction of the frame 11. Along the height direction of the frame 11, the side cover mounting holes 1209 are located above the first cover side cover 1206 and the second cover side cover 1207. This arrangement ensures that both the housing mounting holes 1205s and the side cover mounting holes 1209 are located above the lower housing 1205b, thereby preventing the lower housing 1205b from interfering with the assembly of the housing mounting holes 1205s and the side cover mounting holes 1209. This improves the ease of assembly of the storage box assembly 1205, the first cover side cover 1206, and the second cover side cover 1207.

[0082] like Figure 9 and Figure 11 As shown, in one embodiment, the storage box assembly 1205 is provided with a front fixing part 1205q and a rear fixing part 1205r. The front fixing part 1205q is fixedly connected to the front fender 126, and the rear fixing part 1205r is fixedly connected to the frame 11. This configuration can further improve the connection stability of the storage box assembly 1205 within the all-terrain vehicle 100, enabling the storage box assembly 1205 to store heavier items, thereby improving the storage function of the storage box assembly 1205.

[0083] In some embodiments, the lower housing 1205b is provided with a front fixing part 1205q and a rear fixing part 1205r, and the fixing part is connected to the front fender 126 (see reference). Figure 8 The rear fixing part 1205r is fixedly connected to the frame 11 by screws. In this embodiment, the lower box 1205b bears the weight of the items. Connecting the lower box 1205b to the front fender 126 and the frame 11 can increase the load-bearing capacity of the lower box 1205b, thereby enabling the storage box assembly 1205 to store heavier items and improve the storage effect of the storage box assembly 1205.

[0084] like Figure 12 and Figure 13As shown, in one embodiment, the body panel 12 also includes a heat dissipation grille 12f and a side cover 12g. The side cover 12g is supported by the frame 11 and serves as an exterior component of the all-terrain vehicle 100, protecting the internal components. Specifically, along the length of the frame 11, the side covers 12g are at least partially located between the front fender 126 and the seat assembly 19. The heat dissipation grille 12f is installed at the front end of the side cover 12g, and the side cover 12g at least partially surrounds a heat dissipation space 12ga. The heat dissipation grille 12f communicates with the heat dissipation space 12ga, which has at least one opening (not shown) facing the powertrain 15. This arrangement allows air to enter the heat dissipation space 12ga through the heat dissipation grille 12f and flow towards the powertrain 15 during vehicle operation, thereby improving the heat dissipation of the powertrain 15 and enabling stable operation. Secondly, by cooling the powertrain 15, the overall temperature of the all-terrain vehicle 100 can be reduced, thereby improving the perceived temperature for the driver and passengers and enhancing their comfort. Furthermore, these measures help prevent overheating of the powertrain 15, which could damage it and extend its service life.

[0085] In one implementation, the powertrain 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, such that the opening faces the powertrain 15. The seat assembly 19 is connected to the side cover 12g and is configured to seal the rear of the heat dissipation space 12ga, allowing air within the heat dissipation space 12ga to be supplied to the powertrain 15 through the opening below the heat dissipation space 12ga. This arrangement prevents gas leakage from the rear of the heat dissipation space 12ga, thereby improving the sealing performance of the heat dissipation space 12ga and consequently improving the heat dissipation effect on the powertrain 15. Furthermore, sealing the heat dissipation space 12ga with the seat assembly 19 eliminates the need for additional components, simplifying the structure of the heat dissipation space 12ga and reducing the production cost of the all-terrain vehicle 100.

[0086] In one embodiment, the side cover 12g is provided with mounting holes 12gc, which are located at the front end of the side cover 12g. The heat dissipation grille 12f is at least partially located within the mounting holes 12gc and is fixedly connected to the side cover 12g. This arrangement allows the mounting holes 12gc to face forward, facilitating airflow into the heat dissipation space 12ga during the operation of the all-terrain vehicle 100, thereby improving the heat dissipation effect on the powertrain 15. In some embodiments, the heat dissipation grille 12f is connected to the side cover 12g by screws, which improves the connection stability between the heat dissipation grille 12f and the side cover 12g.

[0087] In one implementation, the side cover 12g includes a first side cover 12gd and a second side cover 12ge, both supported by the frame 11, and distributed along the width of the frame 11. Specifically, a heat dissipation grille 12f is installed at the front end of the first side cover 12gd and / or the second side cover 12ge. The heat dissipation space 12ga includes a first space formed around the first side cover 12gd and a second space formed around the second side cover 12ge. More specifically, both the first and second spaces have at least one opening. This configuration allows the heat dissipation space 12ga to be flexibly positioned according to assembly requirements when it includes either the first or second space, thus preventing interference with the assembly of other components. When the heat dissipation space 12ga includes a first space and a second space, it avoids insufficient air intake caused by air intake from only one side of the heat dissipation space 12ga, thereby improving the air intake volume of the heat dissipation space 12ga and thus improving the heat dissipation effect on the powertrain 15. Through the above arrangement, the heat dissipation space 12ga can be flexibly adjusted in position according to assembly requirements and the heat dissipation requirements of the powertrain 15, thereby improving the assembly flexibility of the heat dissipation space 12ga.

[0088] As an optional implementation, the heat dissipation grille 12f is provided with multiple heat dissipation baffles 12fa, and heat dissipation holes 12fb are formed between two adjacent heat dissipation baffles 12fa. With this configuration, the heat dissipation baffles 12fa can prevent flying stones and gravel from entering the heat dissipation space 12ga through the mounting holes 12gc, thereby preventing flying stones and gravel from damaging the powertrain 15, and thus improving the protection of the internal components of the all-terrain vehicle 100.

[0089] In this embodiment, at least a portion of the heat dissipation holes 12fb are positioned above the upper surface of the front fender 126. This arrangement prevents the front fender 126 from obstructing air from entering the heat dissipation space 12ga through the heat dissipation holes 12fb, thereby improving the air intake efficiency of the heat dissipation holes 12fb.

[0090] In one embodiment, the body panel includes an instrument panel mounting cover 1204 for mounting an instrument panel, and the instrument panel mounting cover 1204 is mounted on the front fender 126. A heat dissipation grille 12f is located on at least one side of the instrument panel mounting cover 1204 along the width direction of the vehicle frame 11. This arrangement prevents the instrument panel mounting cover 1204 from obstructing airflow from the heat dissipation grille 12f into the heat dissipation space 12ga, thereby improving the air intake efficiency of the heat dissipation vents 12fb.

[0091] In one embodiment, the body panel also includes a storage compartment assembly 1205, which is used for storage and is supported by the frame 11. Specifically, the storage compartment assembly 1205 is at least partially located within the heat dissipation space 12ga. More specifically, the storage compartment assembly 1205 includes a storage cover 1205f, which can respectively abut a first cover side cover 12gd and a second cover side cover 12ge on both sides along the width direction of the frame 11, so that the storage cover 1205f can seal the heat dissipation space 12ga. This arrangement makes the heat dissipation space 12ga a basically sealed space, thereby preventing air from leaking inside and outside the heat dissipation space 12ga, so that air can be delivered to the powertrain 15 after passing through the heat dissipation space 12ga, thereby improving the heat dissipation efficiency of the powertrain 15.

[0092] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
