[0002] This application claims priority to Chinese patent application filed on August 28, 2024, with application number 202411200772.X, entitled "All-Terrain Vehicle", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of vehicle technology, and in particular to an all-terrain vehicle. Background Technology

[0004] An all-terrain vehicle (ATV) is a vehicle designed to travel on a variety of complex terrains. ATVs have strong off-road capabilities and can easily handle complex terrains such as mud, sand, snow, and rocks.

[0005] All-terrain vehicles typically include a frame, body panels, running gear, suspension system, powertrain, transmission system, seats, and air filter. The powertrain includes a continuously variable transmission (CVT). In existing technology, the air filter supplies air to the engine for normal operation; the CVT generates heat during operation, requiring air cooling. This setup necessitates a large amount of air for both the air filter and the CVT. However, current all-terrain vehicles have insufficient air intake to meet the air requirements of both the air filter and the CVT.

[0006] Existing all-terrain vehicles have a single type of air supply, which cannot meet the different air requirements of the engine and continuously variable transmission.

[0007] The body panels also include the front bulkhead. The existing front bulkhead is an assembled part, which makes the front bulkhead poorly sealed. This causes air to leak from the front of the all-terrain vehicle into the cab, reducing the driving comfort of the all-terrain vehicle.

[0008] All-terrain vehicles also include doors, but existing doors are not tightly connected to the frame, resulting in poor sealing between the door and the frame, which in turn reduces the overall sealing performance of the all-terrain vehicle. Summary of the Invention

[0057] To enable those skilled in the art to better understand the solutions of this application, the technical solutions in specific embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. 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.

[0058] As shown in Figures 1 and 2, 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 mechanism 16, and a seat 19.

[0059] To clearly illustrate the technical solution of this application, the terms front, rear, left, right, top, and bottom are defined as shown in Figure 1. In this 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.

[0060] The frame 11 serves as the basic framework of the all-terrain vehicle 100, supporting the body panels 12, running gear 13, suspension system 14, powertrain 15, transmission 16, and seat 19. The body panels 12 are at least partially connected to the frame 11. 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. Specifically, the running gear 13 includes front wheels 131 and rear wheels 132, both of which are connected to the frame 11 via the suspension system 14. The powertrain 15 is drive-connected to the running gear 13; specifically, the powertrain 15 can be drive-connected to at least one of the front wheels 131 or the rear wheels 132. The seat 19 is for the driver and passenger.

[0061] Specifically, the vehicle frame 11 is divided along its length, comprising a front frame 111, a middle frame 112, and a rear frame 113 connected sequentially. Along the length of the vehicle frame 11, the middle frame 112 is located between the front frame 111 and the rear frame 113. The body panel 12 is at least partially connected to the middle frame 112 and forms a driver's cab 20 with the middle frame 112, providing seating space for the driver and / or passengers. The middle frame 112 includes a front strut 1121, a strut 1122, and a rear strut 1123. The strut 1122 is located between the front strut 1121 and the rear strut 1123.

[0062] As shown in Figure 2, in one embodiment, the frame 11 is divided along the height direction. The frame 11 includes an upper frame 11a and a lower frame 11b connected together. The upper frame 11a includes an upper frame body 1105 and a front upright 1102 and a rear upright 1104 connected to the upper frame body 1105. The lower frame 11b includes a lower frame body 11bd and a front support column 11ba and a rear support column 11bc connected to the lower frame body 11bd.

[0063] Among them, the front column 1102 is connected to the front support column 11ba, and the rear column 1104 is connected to the rear support column 11bc.

[0064] As shown in Figures 3 to 6, in one embodiment, the powertrain 15 includes an engine 151, an air filter 152, and a continuously variable transmission (CVT) 153. The CVT 153 is connected to the engine 151, and the air filter 152 is connected to the engine 151 and is used to filter the air supplied to the engine 151. An intake chamber 1123f is formed within the rear pillar 1104 and / or the rear support pillar 11bc, and the intake chamber 1123f communicates with the outside.

[0065] Specifically, along the height direction of the rear pillar 1104 and / or the rear support pillar 11bc, the air intake cavity 1123f includes a first air intake 1123i and a second air intake 1123j. The first air intake 1123i is connected to the air filter 152, thus supplying air to the air filter 152 through the first air intake 1123i. The second air intake 1123j is connected to the continuously variable transmission (CVT) 153, thus supplying air to the CVT 153 through the second air intake 1123j. This improves the air intake volume of the all-terrain vehicle 100, meeting the air intake requirements of the air filter 152 and the air-cooling requirements of the CVT 153.

[0066] In one embodiment, the rear pillar 1104 includes a first rear pillar 1104a and a second rear pillar 1104b distributed along the width direction of the frame 11, and the air intake chamber 1123f includes a first air intake chamber 1123g and a second air intake chamber 1123h. The first air intake chamber 1123g is disposed within the first rear pillar 1104a, and the second air intake chamber 1123h is disposed within the second rear pillar 1104b.

[0067] Specifically, the first air intake chamber 1123g is connected to the air filter 152, and the second air intake chamber 1123h is connected to the continuously variable transmission (CVT) 153. This arrangement allows the air filter 152 and the CVT 153 to draw air from both sides of the frame 11, thereby avoiding insufficient air volume on one side of the all-terrain vehicle 100 and helping to meet the air intake requirements of the air filter 152 and the CVT 153.

[0068] As an optional implementation, the first air intake chamber 1123g includes a first air intake port 1123i and a second air intake port 1123j, and the continuously variable transmission (CVT) 153 includes a first air intake port 1531b and a second air intake port 1531c. Specifically, the first air intake port 1531b and the first air intake port 1123i are connected, so that the CVT 153 can intake air from the first air intake chamber 1123g through the first air intake port 1531b. The second air intake port 1531c is connected to the second air intake chamber 1123h, so that the CVT 153 can intake air from the first air intake chamber 1123g through the second air intake port 1531c, thereby enabling the CVT 153 to intake air from both sides of the frame 11.

[0069] More specifically, the second air intake 1123j is connected to the air filter 152. With this configuration, the two air intakes can respectively meet the air intake requirements of the continuously variable transmission 153 and the air filter 152, thus eliminating the need to open two separate cavities on the rear pillar 1104 for the air intake of the continuously variable transmission 153 and the air filter 152, which helps to simplify the structure of the rear pillar 1104.

[0070] In one embodiment, the upper frame 11a also includes a central column 1103 connected to the upper frame body 1105, and the lower frame 11b also includes a central support column 11bb connected to the lower frame body 11bd. The central column 1103 is connected to the central support column 11bb. The central column 1103 is located between the front column 1102 and the rear column 1104, and the central support column 11bb is located between the front support column 11ba and the rear support column 11bc.

[0071] It should be noted that the all-terrain vehicle 100 can be a double-cab or single-cab vehicle. When the all-terrain vehicle 100 is a double-cab vehicle, the seat 19 includes a front seat 191 and a rear seat 192; when the all-terrain vehicle 100 is a single-cab vehicle, the seat 19 only includes the front seat 191. Furthermore, compared to the double-cab vehicle, the single-cab vehicle's upper frame 11a does not include the center pillar 1103, and the lower frame 11b does not include the center support pillar 11bb; the remaining structures are the same. This application uses a double-cab all-terrain vehicle 100 as an example for explanation.

[0072] In this application, the all-terrain vehicle 100 includes a cargo box 27 located behind the rear pillar 1104. The lowest point of the air intake chamber 1123f is higher than the highest point of the cargo box 27, thereby making the air intake chamber 1123f located at a higher position on the all-terrain vehicle 100 to improve the wading performance of the all-terrain vehicle 100.

[0073] In one embodiment, the rear pillar 1104 includes a first sheet metal part 1123k and a second sheet metal part 1123m, which are fixedly connected to form an air intake cavity 1123f. In some embodiments, the first sheet metal part 1123k and the second sheet metal part 1123m are fixed by welding. Furthermore, welding at least a portion of the rear pillar 1104 to sheet metal parts can reduce the processing difficulty of the rear pillar 1104.

[0074] Specifically, a longitudinal plane 101 is defined that is perpendicular to the width direction of the frame 11 and passes through the center of the width of the frame 11. The second sheet metal part 1123m is closer to the longitudinal plane 101 than the first sheet metal part 1123k.

[0075] More specifically, the first sheet metal part 1123k has an air intake opening 1123n that communicates with the outside, and the air intake cavity 1123f communicates with the outside through the air intake opening 1123n.

[0076] More specifically, the body panel 12 includes an air intake grille 125, which covers the air intake opening 1123n and is fixedly connected to the first sheet metal part 1123k.

[0077] As one implementation, the rear pillar 1104 also includes a waterproof structure 1123p, which prevents liquids such as water from entering the air intake chamber 1123f. Specifically, the waterproof structure 1123p is located inside the air intake chamber 1123f and is fixedly connected to the rear pillar 1104 and / or the rear support pillar 11bc. More specifically, the waterproof structure 1123p is fixedly connected to the second sheet metal part 1123m, and the waterproof structure 1123p forms a drainage space 1123q that communicates with the outside. The first air intake 1123i and the second air intake 1123j are formed on the waterproof structure 1123p. Along the length of the frame 11, the first air intake 1123i and the second air intake 1123j are distributed on both sides of the drainage space 1123q. With the above configuration, the drainage space 1123q can discharge liquids such as water from the air intake chamber 1123f, so as to prevent liquids such as water from entering the first air intake 1123i and the second air intake 1123j.

[0078] In this embodiment, the waterproof structure 1123p includes a first flange 1123r, which extends substantially along the first extending plane and defines a transverse plane 102 perpendicular to the length direction of the frame 11. The angle formed between the first extending plane and the transverse plane 102 faces the air intake opening 1123n, thereby blocking liquids such as water entering from the air intake opening 1123n. This prevents liquids such as water from entering the first air intake 1123i and the second air intake 1123j.

[0079] The first flange 1123r extends at least partially along the length of the frame 11 to form a mating portion 1123s. The mating portion 1123s is fixedly engaged with the first sheet metal part 1123k, thereby limiting the position of the waterproof structure 1123p, which facilitates the fixed connection between the waterproof structure 1123p and the second sheet metal part 1123m. Specifically, the mating portion 1123s also abuts against or connects with the air intake grille 125.

[0080] In this embodiment, the waterproof structure 1123p also includes a second flange 1123t, which extends substantially along the second extension plane and defines a reference plane 103 perpendicular to the height direction of the frame 11. The acute angle opening formed between the second extension plane and the reference plane 103 faces the drainage space 1123q.

[0081] Specifically, multiple second flanges 1123t are provided. Along the length of the frame 11, multiple second flanges 1123t are located on both sides of the drainage space 1123q. At least a portion of the second flanges 1123t are located between the drainage space 1123q and the first air inlet 1123i, and at least a portion of the second flanges 1123t are located between the drainage space 1123q and the second air inlet 1123j. This allows water and other liquids that are not blocked by the first flange 1123r to be blocked by the second flanges 1123t and flow to the drainage space 1123q through the second flanges 1123t, thereby discharging the water and other liquids to the outside.

[0082] In another embodiment, the all-terrain vehicle 100 also includes a first air intake pipe and a second air intake pipe (not shown). The first air intake pipe connects to the engine 151, and the second air intake pipe connects to the continuously variable transmission (CVT) 153. Specifically, the first and second air intake pipes are connected to an air intake chamber 1123f, so that the air intake chamber 1123f can supply gas to the first and second air intake pipes, thereby meeting the air demand of the engine 151 and the cooling requirements of the CVT 153.

[0083] Specifically, the first air intake chamber 1123g is connected to the first air intake pipe, and the second air intake chamber 1123h is connected to the second air intake pipe, so that the first air intake pipe and the second air intake pipe respectively draw air from both sides of the frame 11.

[0084] More specifically, there are two second air intake pipes, which are respectively connected to the first air intake port 1123i and the second air intake chamber 1123h, and the second air intake port 1123j is connected to the first air intake pipe. This arrangement allows air to be supplied from both sides of the all-terrain vehicle 100 to the two second air intake pipes to meet the cooling requirements of the continuously variable transmission 153, and to meet the air requirements of the engine 151 through the second air intake port 1123j.

[0085] In some embodiments, the end of the first intake pipe away from the engine 151 is connected to the air filter 152.

[0086] In some embodiments, when the all-terrain vehicle 100 is an electric vehicle, the powertrain 15 includes a drive motor (not shown). In this case, the end of the first air intake pipe away from the air intake chamber 1123f is connected to the drive motor. Furthermore, the first air intake pipe has a built-in fan, which drives the airflow within the first air intake pipe, thereby cooling the drive motor and meeting its cooling requirements.

[0087] It should be noted that when the powertrain 15 includes the engine 151, the first intake manifold can also be used to cool the engine 151.

[0088] As shown in Figure 7, in one embodiment, a support pillar 1122 is disposed between the front seat 191 and the rear seat 192. The support pillar 1122 includes an upper support pillar 1122a and a lower support pillar 1122b, which are connected. Specifically, the lower support pillar 1122b is at least partially located in front of the upper support pillar 1122a, so that an extended space is formed behind the lower support pillar 1122b to increase the space in front of the rear seat 192. Through the above arrangement, the extended space can increase the activity space of the rear passengers, thereby improving the riding comfort of the rear passengers.

[0089] It should be noted that when the seat 19 only includes the front seat 191, the pillar 1122 is located behind the front seat 191, so that an extended space is formed behind the lower pillar 1122b to increase the space behind the front seat 191. Through the above arrangement, the space behind the front seat 191 can be increased, thereby improving the space utilization of the all-terrain vehicle 100.

[0090] Specifically, the pillar 1122 also includes a transition pillar 1122c, which is located between the upper pillar 1122a and the lower pillar 1122b. The upper end of the transition pillar 1122c is connected to the upper pillar 1122a, and the lower end of the transition pillar 1122c is connected to the lower pillar 1122b. The lower end of the transition pillar 1122c is at least partially located in front of the upper pillar 1122a, and the upper end of the transition pillar 1122c is at least partially located behind the lower pillar 1122b. The transition pillar 1122c allows the lower pillar 1122b to be positioned in front of the upper pillar 1122a, thereby increasing the extended space in front of the rear seats 192.

[0091] As shown in Figure 8, in one embodiment, the all-terrain vehicle 100 includes a door 22, which includes a door body 221 and a sealing structure 222. The sealing structure 222 is used to seal the gap between the door body 221 and the upper frame 11a.

[0092] Specifically, the support column 1122 includes a column guard plate 127, which covers the transition support column 1122c. The column guard plate 127 is fixedly connected to the upper support column 1122a and / or the lower support column 1122b. The column guard plate 127 cooperates with the upper support column 1122a and the lower support column 1122b to form a central sealing surface 1122e, which is used to cooperate with the sealing structure 222 for sealing. The central sealing surface 1122e is substantially located on the same plane. Through the above arrangement, the flatness of the central sealing surface 1122e on the support column 1122 can be improved, which is conducive to improving the fit between the sealing structure 222 and the central sealing surface 1122e, thereby improving the sealing performance between the sealing structure 222 and the support column 1122, and thus improving the sealing performance of the door 22.

[0093] More specifically, the door 22 includes a front door 2211 and a rear door 2212. The sealing structure 222 includes a front door sealing strip 2221 and a rear door sealing strip 2222. When the door body 221 is in the closed state, the front door sealing strip 2221 is located between the central sealing surface 1122e and the front door 2211, and the rear door sealing strip 2222 is located between the central sealing surface 1122e and the rear door 2212. With the above arrangement, the front door 2211 and the rear door 2212 can be sealed with a single central sealing surface 1122e, which simplifies the sealing surface structure of the front door 2211 and the rear door 2212.

[0094] As shown in Figures 8, 9, and 10, the frame 11 includes a top beam structure 115. The top beam structure 115 includes a longitudinal beam 1151 extending substantially along the length of the frame 11. The longitudinal beam 1151 is at least partially recessed to form a first recess 1151c and a second recess 1151d. The first recess 1151c and the second recess 1151d enhance the structural strength of the longitudinal beam 1151, and both recesses extend substantially along the length of the frame 11. This arrangement allows for stress dispersion in the longitudinal beam 1151 through the first recess 1151c and the second recess 1151d, thereby increasing the structural strength of the longitudinal beam 1151, improving its impact resistance, and ultimately enhancing the safety of the all-terrain vehicle 100.

[0095] Specifically, the first recess 1151c includes a sealing surface 1151e, which is substantially perpendicular to the width direction of the frame 11. When the door body 221 is in the closed state, the sealing structure 222 is located between the sealing surface 1151e and the door body 221. This arrangement ensures that the sealing surface 1151e is substantially on the same plane, thereby preventing misalignment of the sealing structure 222 on the sealing surface 1151e and improving the sealing performance of the sealing structure 222 and the sealing surface 1151e.

[0096] More specifically, the first recess 1151c includes a gap surface 1151f, which is substantially perpendicular to the sealing surface 1151e and perpendicular to the height direction of the frame 11. Furthermore, when the door body 221 is closed, the distance between the door body 221 and the gap surface 1151f along the height direction of the frame 11 is equidistant everywhere. This arrangement helps to ensure more uniform airflow between the door body 221 and the gap surface 1151f during the operation of the all-terrain vehicle 100, thereby reducing the noise generated during the operation of the all-terrain vehicle 100.

[0097] In one implementation, a longitudinal plane 101 is defined that is perpendicular to the width direction of the frame 11 and passes through the center of the width of the frame 11. The first recess 1151c is located on the side of the longitudinal beam 1151 away from the longitudinal plane 101 and is located at the lower part of the longitudinal beam 1151. The second recess 1151d is located on the side of the longitudinal beam 1151 close to the longitudinal plane 101 and is located at the upper part of the longitudinal beam 1151.

[0098] As shown in Figures 11 and 12, in one embodiment, the body panel 12 also includes an interior trim panel 126 located within the driver's cabin 20. Specifically, the interior trim panel 126 is at least partially fixed to the longitudinal beam 1151. The interior trim panel 126 has at least one notch 1261, which overlaps with the longitudinal beam 1151 in at least one direction. The portion of the longitudinal beam 1151 overlapping the notch 1261 forms a grip portion 1151k for holding, to help the driver and passenger maintain their balance.

[0099] As shown in Figures 13 to 17, in one embodiment, the cargo box 27 is at least partially located at the rear of the frame 11. The cargo box 27 includes a fastener 273, a quick-release mechanism 274, and a secondary cargo box 275. The fastener 273 is connected to the frame 11, and the fastener 273 and the secondary cargo box 275 are detachably connected via the quick-release mechanism 274.

[0100] The quick-release mechanism 274 includes a quick-release body 2741, an operating component 2742, an actuating component 2743, and a transmission component 2744. The quick-release body 2741 is fixedly connected to the auxiliary cargo box 275 and is used to support the auxiliary cargo box 275. The transmission component 2744, the operating component 2742, and the actuating component 2743 are used to realize the detachable connection between the quick-release body 2741 and the fixing component 273, thereby realizing the detachable connection between the auxiliary cargo box 275 and the fixing component 273.

[0101] Specifically, one side of the quick-release body 2741 has a fixing portion 2741d that connects to the auxiliary cargo box 275, and the other side of the quick-release body 2741 has a locking portion 2741c that can engage with the fixing member 273. The transmission member 2744 is a shaft, and the fixing portion 2741d and the locking portion 2741c are located on both sides of the quick-release body 2741 along a direction perpendicular to the axial direction of the transmission member 2744. In some embodiments, the auxiliary cargo box 275 is connected to the fixing portion 2741d by screws.

[0102] More specifically, the transmission member 2744 passes through the quick-release body 2741 along its axial direction, and the transmission member 2744 is movable relative to the quick-release body 2741 along its axial direction. The operating member 2742 is rotatably connected to one end of the transmission member 2744, and the operating member 2742 is used to drive the transmission member 2744 to move. The actuator 2743 is connected to the other end of the transmission member 2744, and the movement of the transmission member 2744 can drive the actuator 2743 to move, so that the actuator 2743 can switch between different working positions, thereby realizing the detachable connection between the quick-release mechanism 274 and the fixing member 273. In this application, the axial direction of the transmission member 2744 is the height direction of the frame 11.

[0103] In this embodiment, the actuator 2743 has a movable position, a snap-fit ​​position, and a disengaged position. These positions are the working positions of the actuator 2743.

[0104] As shown in Figure 15, when the actuator 2743 is in the movable position, there is a gap between the actuator 2743 and the fixing member 273, and the quick-release body 2741 can move relative to the fixing member 273. At this time, the actuator 2743 no longer provides preload to the fixing member 273, so that the quick-release mechanism 274 can move along the extension direction of the fixing member 273.

[0105] As shown in Figure 16, when the actuator 2743 is in the latching position, the actuator 2743 abuts against the fixing member 273, and the actuator 2743 can cooperate with the latching part 2741c to connect the quick-release mechanism 274 to the fixing member 273. At this time, the latching part 2741c and the actuator 2743 abut against the upper and lower ends of the fixing member 273 respectively, and the actuator 2743 can provide a pre-tightening force to the fixing member 273, thereby fixing the relative position of the quick-release body 2741 and the fixing member 273.

[0106] As shown in Figure 17, when the actuator 2743 is in the separated position, the actuator 2743 and the fixing member 273 do not overlap along the axial direction of the transmission member 2744, and the quick release mechanism 274 can be separated from the fixing member 273.

[0107] In summary, by adjusting the operating component 2742 to drive the transmission component 2744 to move, the actuator 2743 can switch between the engaging position, the moving position, and the disengaging position, thereby achieving quick assembly and disassembly of the auxiliary cargo box 275 and the chassis 11.

[0108] In one embodiment, the quick-release body 2741 has a through hole 2741a extending through itself. The through hole 2741a extends axially along the transmission member 2744, which is located within the through hole 2741a and can rotate within it. Specifically, the operating member 2742 can rotate the actuator 2743 via the transmission member 2744, so that the actuator 2743 can be in the disengaged position.

[0109] In one embodiment, the quick-release body 2741 extends along a preset direction, which is substantially parallel to the axial direction of the transmission member 2744. The operating member 2742 and the actuating member 2743 are distributed on both sides of the quick-release body 2741 along the preset direction. When the operating member 2742 is in the latching position, the actuating member 2743 and the latching portion 2741c respectively latch onto both sides of the fixing member 273 along the preset direction. In this application, the preset direction is the height direction of the frame 11. This configuration fixes both ends of the quick-release body 2741 to the fixing member 273, thereby improving the connection stability between the quick-release body 2741 and the fixing member 273, and further improving the connection stability between the auxiliary cargo box 275 and the frame 11.

[0110] As shown in Figure 14, in one embodiment, the quick-release body 2741 has a support portion 2741e, which is located on the fixing portion 2741d. The support portion 2741e abuts against and supports the auxiliary cargo box 275, and the fixing portion 2741d is fixedly connected to the auxiliary cargo box 275.

[0111] As shown in Figures 18, 19, and 20, in one implementation, the door 22 includes a quick-release device 223, and the door body 221 is rotatably connected to the frame 11 via the quick-release device 223. The quick-release device 223 includes a door fastener 2231, a locking member 2232, a first fixing member 2233, and a second fixing member 2234. The first fixing member 2233 is fixedly connected to the frame 11, and the second fixing member 2234 is connected to the door body 221. The door fastener 2231 and the locking member 2232 are used to connect the first fixing member 2233 and the second fixing member 2234, thereby connecting the door body 221 and the frame 11.

[0112] Specifically, the first fastener 2233 has a first through hole 2233a and a second through hole 2233b. The axis of the first through hole 2233a extends substantially along the height direction of the frame 11. Viewed from the width direction of the frame 11, the axis of the second through hole 2233b is substantially perpendicular to the axis of the first through hole 2233a. One end of the second through hole 2233b connects to the first through hole 2233a, and the other end connects to the surface of the first fastener 2233. The door fastener 2231 passes through the second fastener 2234 and is at least partially located within the first through hole 2233a.

[0113] When the locking member 2232 is in the assembled state, it passes through the second through hole 2233b and abuts against the door fastener 2231. At this time, the locking member 2232 has a preload on the door fastener 2231, so that the door fastener 2231 is limited to the first fixing member 2233, thereby realizing the connection between the door body 221 and the frame 11.

[0114] When the locking member 2232 is in the disassembled state, the locking member 2232 is separated from the door fastener 2231, so that the door fastener 2231 can be separated from the first fixing member 2233, thereby allowing the door body 221 to be separated from the frame 11.

[0115] In summary, by switching the state of the locking element 2232, the door body 221 and the frame 11 can be connected and separated, which facilitates the quick assembly and disassembly of the door body 221 and the frame 11.

[0116] In this embodiment, the second fixing member 2234 is rotatably connected to the door fastener 2231, which is essentially an axis, so that the second fixing member 2234 can rotate around the axis of the door fastener 2231, so that the door body 221 can rotate relative to the frame 11.

[0117] As shown in Figures 21 and 22, the cargo box 27 also includes a cargo box panel 271 and a support plate 276. The support plate 276 is located in front of the cargo box panel 271, which is used to carry goods. The support plate 276 is rotatably connected to the frame 11, allowing it to rotate relative to the frame 11 to a first rotation position. The support plate 276 also has a support surface 2761, and the cargo box panel 271 has an upper surface 2711. When the support plate 276 is in the first rotation position, the support surface 2761 of the support plate 276 and the upper surface 2711 of the cargo box panel 271 are substantially on the same plane, thereby increasing the cargo space of the cargo box 27.

[0118] In one implementation, the seat 19 is located in front of the cargo box 27, and a storage space 196 is formed behind the seat 19, which can hold personal belongings carried by the driver or passenger. The storage space 196 has an opening at the top, which facilitates the driver or passenger in storing items.

[0119] Specifically, when the support plate 276 is in the first rotating position, the storage space 196 is located below the support plate 276, so that the support plate 276 can cover the opening of the storage space 196, thus preventing items in the storage space 196 from leaving the storage space 196 through the opening.

[0120] More specifically, the support plate 276 can also rotate relative to the frame 11 to a second rotation position. When the support plate 276 is in the second rotation position, the support surface 2761 and the upper surface 2711 of the cargo box panel 271 are on different planes. At this time, an extension space 197 is formed between the support plate 276 and the seat 19, and the extension space 197 is connected to the storage space 196, thereby increasing the space of the storage space 196.

[0121] As shown in Figures 23 and 24, in one embodiment, the body panel 12 includes a front bulkhead 121, which is connected to the front frame 111 and located in front of the cab 20 to isolate the electrical system 18 on the front frame 111 from the cab 20, thereby improving the safety of the all-terrain vehicle 100. The electrical system 18 includes an instrument panel 181, which is supported by the frame 11 and located within the cab 20. The frame 11 also includes a mounting frame 114, on which the instrument panel 181 is located and connected. Specifically, along the height direction of the frame 11, the highest point of the instrument panel 181 is lower than the highest point of the front bulkhead 121, and the mounting frame 114 is detachably connected to the mid-frame 112, while the front bulkhead 121 is a single piece.

[0122] In some embodiments, both the frame 11 and the mounting frame 114 are made of structural metal, and the frame 11 defines the bottom of the cockpit 20 located behind the front frame 11. The front bulkhead 121 is made of sheet plastic and has at least one instrument bracket opening.

[0123] When the mounting frame 114 and the mid-frame 112 are disassembled, the front bulkhead 121 can be installed from inside the cab 20 to the front of the cab 20 and connected to the front frame 111. This arrangement avoids interference between the mounting frame 114 and the assembly of the front bulkhead 121, which would otherwise occur due to the mounting frame 114 being integrally formed with the frame 11, thus improving the assembly efficiency of the all-terrain vehicle 100. Furthermore, when assembling the front bulkhead 121, the mounting frame 114 is removed from the frame 11 to prevent interference with the assembly of the front bulkhead 121. This facilitates the complete assembly of the front bulkhead 121 onto the frame 11, avoiding any reduction in the sealing performance of the front bulkhead 121 due to disassembly.

[0124] As shown in Figure 25, as one embodiment, this application also provides a method for assembling an all-terrain vehicle, the method comprising the following steps:

[0125] Step S1: Install the front bulkhead 121 to the rear of the front frame 111, such that the front bulkhead 121 at least partially constitutes the front of the cockpit 20.

[0126] Step S2: Install the mounting frame 114 to the frame 11 through the instrument bracket opening, and extend the front bulkhead 121 to cover and wrap at least one connection point between the mounting frame 114 and the frame 11.

[0127] Step S3: Install the instrument panel 181 onto the mounting frame 114.

[0128] By following the above steps, interference between the dashboard 181 and the mounting frame 114 and the assembly of the front bulkhead 121 can be avoided, which is conducive to the complete assembly of the front bulkhead 121 with the frame 11 and improves the sealing performance of the front bulkhead 121.

[0129] In this embodiment, when the mounting frame 114 and the mid-frame 112 are in a disassembled state, the mid-frame 112 has a mounting channel 1125 extending along the length of the frame 11 to the front frame 111, and the front bulkhead 121 can pass through the mounting channel 1125 and connect to the front frame 111.

[0130] Specifically, the front strut 1121 includes a first front strut 1121a and a second front strut 1121b, which are distributed along the width direction of the frame 11. The two ends of the mounting frame 114 are detachably connected to the first front strut 1121a and the second front strut 1121b, respectively.

[0131] More specifically, the contact between the mounting frame 114 and the center frame 112 is a surface contact, and the mounting frame 114 and the center frame 112 are detachably connected at the surface contact point by fasteners. The surface contact connection method can increase the connection area between the mounting frame 114 and the center frame 112, thereby improving the connection stability between the mounting frame 114 and the center frame 112.

[0132] As shown in Figures 26 and 27, in one embodiment, the front bulkhead 121 includes a bulkhead fixing part 1211, which is connected to the frame 11. Specifically, the contact surface on the mounting frame 114 with the mid-frame 112 is defined as the first surface 1141, and the contact surface on the mid-frame 112 with the mounting frame 114 is defined as the second surface 1124. The bulkhead fixing part 1211 is located between the first surface 1141 and the second surface 1124, so that fasteners can pass through the mounting frame 114, the bulkhead fixing part 1211, and the mid-frame 112 and be fixed by a connector. In some embodiments, the fastener is a bolt, and the connector is a nut.

[0133] As shown in Figures 24 and 28, in one embodiment, the mounting frame 114 has a fixing portion 1142, which is detachably connected to the front frame 111. The mounting frame 114 extends at least partially forward to form the fixing portion 1142, thereby enabling the mounting frame 114 to be connected to the front frame 111 located at the front of the frame 11 via the fixing portion 1142.

[0134] Specifically, the contact between the fixing part 1142 and the front frame 111 is a surface contact, and the fixing part 1142 and the front frame 111 are detachably connected at the surface contact point by fasteners. Through the above arrangement, the surface contact connection method can increase the connection area between the fixing part 1142 and the front frame 111, thereby improving the connection stability between the fixing part 1142 and the front frame 111.

[0135] As shown in Figures 24 and 28, in one embodiment, the mounting frame 114 includes a horizontal tube 1143 and an arched tube 1144. The horizontal tube 1143 extends along the width direction of the frame 11, and the arched tube 1144 is connected to the horizontal tube 1143. Specifically, the horizontal tube 1143 is detachably connected to the mid-frame 112. In this embodiment, both ends of the horizontal tube 1143 along the width direction of the frame 11 are detachably connected to the first front support 1121a and the second front support 1121b, respectively, and both ends of the arched tube 1144 are fixedly connected to the horizontal tube 1143. Furthermore, a fixing part 1142 is provided on the horizontal tube 1143 and connected to the horizontal tube 1143, so that the horizontal tube 1143 can be detachably connected to the front frame 111.

[0136] In this embodiment, the all-terrain vehicle 100 includes a control panel 122 located within the driver's cab 20. An instrument panel 181 is at least partially located on the control panel 122.

[0137] Specifically, both the arched tube 1144 and the horizontal tube 1143 are provided with panel connection points 1145, which are fixedly connected to the control panel 122.

[0138] In one embodiment, the all-terrain vehicle 100 includes a steering system 21 for controlling the steering of the all-terrain vehicle 100. Specifically, the steering system 21 includes a steering wheel assembly 211 for controlling the steering of the front wheels 131. A steering wheel assembly connection point 1146 is provided on the mounting frame 114, and the steering wheel assembly connection point 1146 is fixedly connected to the steering wheel assembly 211. The steering wheel assembly connection point 1146 is at least partially located between the horizontal tube 1143 and the arched tube 1144.

[0139] In this embodiment, the steering system 21 further includes a steering assist device 212, which is connected to the steering wheel assembly 211 so that the steering assist device 212 can assist the steering wheel assembly 211 in steering. A mechanism mounting bracket 1147 is provided on the mounting frame 114, and the steering assist device 212 is fixedly connected to the mechanism mounting bracket 1147.

[0140] As shown in Figure 29, in one embodiment, the transmission mechanism 16 includes a drive shaft 161. Specifically, the drive shaft 161 includes a first drive shaft 1611 and a second drive shaft 1612. The first drive shaft 1611 has a first drive end 1611a and a second drive end 1611b at its two ends. The first drive end 1611a is connected to the walking system 13, and the second drive end 1611b is connected to the second drive shaft 1612. The end of the second drive shaft 1612 away from the first drive end 1611a is connected to the powertrain 15. This configuration connects the walking system 13 and the powertrain 15 via the first drive shaft 1611 and the second drive shaft 1612. Furthermore, configuring the transmission mechanism 16 as a two-section structure composed of the first drive shaft 1611 and the second drive shaft 1612 facilitates installation of the transmission mechanism 16 within the limited space of the all-terrain vehicle 100.

[0141] In this application, the all-terrain vehicle 100 includes a fuel tank 17 supported by a frame 11 and located close to the powertrain 15, so as to shorten the connection line between the fuel tank 17 and the powertrain 15.

[0142] Specifically, a plane perpendicular to the width direction of the frame 11 and passing through the center of the width of the frame 11 is defined as the longitudinal plane 101. The longitudinal plane 101 passes through the first transmission end 1611a, and the second transmission shaft 1612 and the fuel tank 17 are located on opposite sides of the longitudinal plane 101. This arrangement allows the first transmission shaft 1611 to be arranged obliquely, i.e., the axis of the first transmission shaft 1611 forms an angle with the longitudinal plane 101. Consequently, the second transmission shaft 1612, connected to the first transmission shaft 1611, can also be arranged obliquely, thus placing the second transmission shaft 1612 substantially on one side of the longitudinal plane 101. Furthermore, since the second transmission shaft 1612 and the fuel tank 17 are substantially located on opposite sides of the longitudinal plane 101, the second transmission shaft 1612 can provide more space for the fuel tank 17, which is beneficial for installing a larger fuel tank 17.

[0143] More specifically, the minimum distance between the second transmission end 1611b and the longitudinal plane 101 along the width direction of the frame 11 is defined as the first distance L1. The minimum distance between the end of the second transmission shaft 1612 connected to the powertrain 15 and the longitudinal plane 101 along the width direction of the frame 11 is defined as the second distance L2. The sum of the axial length L3 of the first transmission shaft 1611 and the axial length of the second transmission shaft 1612 is defined as the transmission length L4. The acute angle between the axis of the first transmission shaft 1611 and the longitudinal plane 101 is α1, and the acute angle between the axis of the second transmission shaft 1612 and the longitudinal plane 101 is α2. The ratio of the first distance L1 to the axial length L3 of the first transmission shaft 1611 is Sinα1, and the ratio of the second distance L2 to the transmission length L4 is Sinα2. Sinα1 is approximately equal to Sinα2. With the above configuration, the axial extension direction of the first drive shaft 1611 and the axial extension direction of the second drive shaft 1612 are substantially aligned, which reduces the transmission loss between the first drive shaft 1611 and the second drive shaft 1612, thereby improving the transmission efficiency of the powertrain 15 driving the walking system 13. It should be noted that the error of "substantially equal to" in this application is ±1%.

[0144] In this embodiment, the ratio of the first distance L1 to the axial length L3 of the first drive shaft 1611 ranges from 0.03 to 0.06; the ratio of the second distance L2 to the transmission length L4 ranges from 0.04 to 0.06. Specifically, the ratio of the first distance L1 to the axial length L3 of the first drive shaft 1611 ranges from 0.04 to 0.05; the ratio of the second distance L2 to the transmission length L4 ranges from 0.045 to 0.056. More specifically, the ratio of the first distance L1 to the axial length L3 of the first drive shaft 1611 is 0.045; the ratio of the second distance L2 to the transmission length L4 is 0.051.

[0145] By setting the above, the tilt angle of the first drive shaft 1611 and the second drive shaft 1612 relative to the longitudinal plane 101 can be avoided if the two ratios are too large, thus ensuring that there is enough space on the side away from the fuel tank 17 to install parts.

[0146] In addition, it can avoid the situation where the tilt angle between the first drive shaft 1611 and the second drive shaft 1612 relative to the longitudinal plane 101 is too small when the above two ratios are too small, so that the second drive shaft 1612 can reserve enough space for the fuel tank 17, which is beneficial for installing a large-volume fuel tank 17.

[0147] In this embodiment, the angle α1 formed by the axis of the first drive shaft 1611 and the longitudinal plane 101 ranges from 2° to 5°; the angle α2 formed by the axis of the second drive shaft 1612 and the longitudinal plane 101 ranges from 2° to 5°. Specifically, the angle α1 formed by the axis of the first drive shaft 1611 and the longitudinal plane 101 ranges from 3° to 4°; the angle α2 formed by the axis of the second drive shaft 1612 and the longitudinal plane 101 ranges from 3° to 4°. More specifically, the angle α1 formed by the axis of the first drive shaft 1611 and the longitudinal plane 101 is 3.5°; the angle α2 formed by the axis of the second drive shaft 1612 and the longitudinal plane 101 is 3.5°.

[0148] With the above settings, the tilt angle of the first drive shaft 1611 and the second drive shaft 1612 relative to the longitudinal plane 101 can be avoided if α1 and / or α2 are too large, thus ensuring that there is enough space on the side away from the fuel tank 17 to install parts.

[0149] Furthermore, the above settings can prevent the tilt angle between the first drive shaft 1611 and the second drive shaft 1612 and the longitudinal plane 101 from being too small due to α1 being too small and / or α2 being too small, thereby allowing the second drive shaft 1612 to reserve sufficient space for the fuel tank 17.

[0150] In this application, the ratio of the second distance L2 to the volume of the fuel tank 17 ranges from 1.9 mm / L to 3 mm / L. Specifically, the ratio ranges from 2.1 mm / L to 2.7 mm / L. More specifically, the ratio ranges from 2.3 mm / L to 2.6 mm / L. This configuration avoids excessive space wastage due to an excessively large second distance L2, thereby improving the space utilization of the all-terrain vehicle 100; it also avoids interference between the fuel tank 17 and the second drive shaft 1612 due to an excessively large fuel tank 17. Furthermore, it avoids an excessively small second distance L2, which would result in an excessively small volume of the fuel tank 17, thereby improving the range of the all-terrain vehicle 100.

[0151] As shown in Figure 30, in one embodiment, the frame 11 also includes a bottom frame 116 and a seat support frame 117. The bottom frame 116 is located at the lower part of the frame 11, that is, the bottom frame 116 is the chassis of the all-terrain vehicle 100. The seat support frame 117 is fixedly connected to the bottom frame 116.

[0152] Specifically, the seat support frame 117 includes a support arm 1171 and a support member 1172. The bottom frame 116 is fixedly connected to one end of the support arm 1171 via the support member 1172, making the support arm 1171 a cantilever beam structure. The seat 19 is supported by and fixedly connected to the support arm 1171. With this arrangement, since no components are located below the support arm 1171, it is convenient to place items under the seat 19.

[0153] More specifically, the support arm 1171 extends at least partially along the width of the frame 11. The end of the support arm 1171 away from the door 22 is connected to the bottom frame 116. This arrangement increases the usable space on the side of the door body 221, thereby improving the space utilization of the all-terrain vehicle 100.

[0154] In one embodiment, the seat support frame 117 includes at least one mounting member 1173, which is located on and fixedly connected to the support arm 1171. The mounting member 1173 abuts against and is fixedly connected to the seat 19. The mounting member 1173 extends along the length of the vehicle frame 11.

[0155] Specifically, the mounting component 1173 has a support surface 1173a extending along the length of the frame 11. The support surface 1173a abuts against the seat 19 so that it can support the seat 19. The support surface 1173a is substantially perpendicular to the height direction of the frame 11. This arrangement increases the contact area between the support surface 1173a and the seat 19, thereby improving the support effect of the support surface 1173a and the support arm 1171 on the seat 19.

[0156] As shown in Figure 31, in one embodiment, the frame 11 includes a side support 118 for the driver and passengers to step on. The side support 118 extends at least partially along the length of the frame 11 and is fixedly connected to the center frame 112. Specifically, a longitudinal plane 101 is defined perpendicular to the width direction of the frame 11 and passes through the center of the width of the frame 11. The maximum distance between the center frame 112 and the longitudinal plane 101 along the width direction of the frame 11 is less than the maximum distance between the side support 118 and the longitudinal plane 101 along the width direction of the frame 11. This arrangement facilitates the driver and passengers getting on and off the vehicle by using the side support 118 for stepping, thereby improving the convenience of getting on and off the vehicle.

[0157] In one embodiment, the side bracket 118 is located on at least one side of the driver's cab 20 along the width direction of the frame 11.

[0158] Specifically, one end of the side bracket 118 is connected to the front support column 1121, and the other end of the side bracket 118 is connected to the rear support column 1123. In one embodiment, the side bracket 118 is welded to the front support column 1121 and the rear support column 1123 respectively.

[0159] As shown in Figure 32, in one embodiment, the longitudinal beam 1151 is located above the front pillar 1102, the middle pillar 1103, and the rear pillar 1104. The longitudinal beam 1151 is integrally formed with the front pillar 1102, and the middle pillar 1103 and the rear pillar 1104 are fixedly connected to the longitudinal beam 1151, so that the longitudinal beam 1151, the front pillar 1102, the middle pillar 1103, and the rear pillar 1104 can cooperate to form a substantially continuous door sealing surface 1101. The door sealing surface 1101 cooperates with the sealing structure 222 to seal the gap between the door body 221 and the upper frame 11a. The substantially continuous door sealing surface 1101 means that the entire door sealing surface 1101 has no cross-section, that is, the entire door sealing surface 1101 is not interrupted. By adopting the above settings, it is possible to avoid the door sealing surface 1101 from being broken, which would prevent the broken part from fitting with the sealing structure 222, thereby improving the sealing performance between the upper frame 11a and the sealing structure 222, and thus improving the sealing performance of the door 22.

[0160] As shown in Figures 32 to 34, in one embodiment, the longitudinal beam 1151 further includes a connecting surface 1151m, which is located below the door sealing surface 1101. More specifically, the connecting surface 1151m connects the upper end of the center pillar 1103 and the upper end of the rear pillar 1104, so that the door sealing surface 1101 is substantially continuous.

[0161] With the above settings, the connecting surface 1151m can prevent the central pillar 1103 from protruding from the door sealing surface 1101 when the central pillar 1103 and the longitudinal beam 1151 are connected, and prevent the rear pillar 1104 from protruding from the door sealing surface 1101 when the rear pillar 1104 is connected to the longitudinal beam 1151, so that the connecting surface 1151m can form a basically continuous surface, which is beneficial to improving the sealing performance of the door body 221.

[0162] In one embodiment, the front pillar 1102 includes a first front pillar 1102a and a second front pillar 1102b distributed along the width direction of the frame 11. The middle pillar 1103 includes a first middle pillar 1103a and a second middle pillar 1103b distributed along the width direction of the frame 11. The rear pillar 1104 includes a first rear pillar 1104a and a second rear pillar 1104b distributed along the width direction of the frame 11. The longitudinal beam 1151 includes a first longitudinal beam 1151a and a second longitudinal beam 1151b distributed along the width direction of the frame 11. The first longitudinal beam 1151a is integrally formed with the first front pillar 1102a. The first middle pillar 1103a and the first rear pillar 1104a are both fixedly connected to the first longitudinal beam 1151a. The second longitudinal beam 1151b is integrally formed with the second front pillar 1102b. The second middle pillar 1103b and the second rear pillar 1104b are both fixedly connected to the second longitudinal beam 1151b.

[0163] Specifically, the door sealing surface 1101 includes a first door sealing surface 1101a and a second door sealing surface 1101b distributed along the width direction of the frame 11. The first longitudinal beam 1151a, the first front pillar 1102a, the first middle pillar 1103a, and the first rear pillar 1104a cooperate to form the first door sealing surface 1101a for cooperating with the sealing structure 222. The second longitudinal beam 1151b, the second front pillar 1102b, the second middle pillar 1103b, and the second rear pillar 1104b cooperate to form the second door sealing surface 1101b for cooperating with the sealing structure 222.

[0164] More specifically, the sealing structure 222 includes a front door sealing strip 2221 and a rear door sealing strip 2222. The central pillar 1103 has a first central sealing surface 1103c for engaging with the front door sealing strip 2221 and the rear door sealing strip 2222. When the door body 221 is closed, the front door sealing strip 2221 is located between the first central sealing surface 1103c and the front door 2211, and the rear door sealing strip 2222 is located between the first central sealing surface 1103c and the rear door 2212. The first central sealing surface 1103c can simultaneously engage with the front door sealing strip 2221 and the rear door sealing strip 2222 to form a seal. With this configuration, the seal between the upper frame 11a and the front door 2211, and between the upper frame 11a and the rear door 2212, can be achieved through a single first central sealing surface 1103c.

[0165] In one embodiment, the rear pillar 1104 is formed with a rear sealing surface 1104c for engaging with the rear door sealing strip 2222. Specifically, the longitudinal beam 1151 and the front pillar 1102 form a mating sealing surface 1101d, and the mating sealing surface 1101d, the first middle sealing surface 1103c and the rear sealing surface 1104c form a door sealing surface 1101.

[0166] In one embodiment, the central support column 11bb has a second central sealing surface 11be, which is substantially continuous with the door sealing surface 1101. The second central sealing surface 11be can cooperate with the front door sealing strip 2221 to seal the front door 2211, and can cooperate with the rear door sealing strip 2222 to seal the rear door 2212.

[0167] As shown in Figures 32 and 35, in one embodiment, the frame 11 also includes a plurality of crossbeams 1152. The crossbeams 1152 are distributed along the length of the frame 11. Furthermore, each crossbeam 1152 is connected at both ends to a first longitudinal beam 1151a and a second longitudinal beam 1151b, respectively.

[0168] More specifically, the structures of the multiple crossbeams 1152 are basically the same to improve the versatility of the crossbeams 1152.

[0169] As shown in Figures 32 and 35, in this embodiment, each crossbeam 1152 has a connecting sheet metal part 1153 at both ends. One end of the connecting sheet metal part 1153 is fixedly connected to the longitudinal beam 1151, and the end of the connecting sheet metal part 1153 away from the longitudinal beam 1151 forms an adapter part 1153a. The distance between the first longitudinal beam 1151a and the second longitudinal beam 1151b along the width direction of the frame 11 is not a fixed value. The adapter part 1153a allows the crossbeam 1152 to adapt to different distances between the first longitudinal beam 1151a and the second longitudinal beam 1151b. With the above arrangement, the crossbeam 1152 can be installed between the non-fixed first longitudinal beam 1151a and the second longitudinal beam 1151b, thereby allowing the crossbeam 1152 to be installed at any position between the first longitudinal beam 1151a and the second longitudinal beam 1151b, thus improving the ease of connection between the crossbeam 1152 and the longitudinal beam 1151.

[0170] Specifically, the adapter 1153a has a layout area 1153b, which can have adjustment holes 1153c at different positions. Both ends of the crossbeam 1152 are provided with connecting pipes 1152a that penetrate the crossbeam 1152 radially. The connecting pipes 1152a pass through the adjustment holes 1153c and are fixedly connected to them. Through this arrangement, the different positions of the adjustment holes 1153c allow for different connection positions between the crossbeam 1152 and the adapter 1153a, thereby adjusting the overall length of the crossbeam 1152 and the adapter 1153a, so that the crossbeam 1152 can be installed between the non-fixed first longitudinal beam 1151a and the second longitudinal beam 1151b.

[0171] In one embodiment, the crossbeam 1152 includes a first crossbeam 1152b and a second crossbeam 1152c located behind the first crossbeam 1152b. At least one of the first crossbeam 1152b and the second crossbeam 1152c is a sheet metal part. The first crossbeam 1152b is provided with a windshield fixing part 1152e and a rearview mirror fixing part 1152f, both of which are located in front of the first crossbeam 1152b. The all-terrain vehicle 100 includes a windshield assembly and a rearview mirror assembly 23. The windshield fixing part 1152e is fixedly connected to the windshield assembly, and the rearview mirror fixing part 1152f is fixedly connected to the rearview mirror assembly 23.

[0172] As shown in Figures 36 and 37, in one embodiment, the top beam structure 115 includes a first crossbeam 1152b and a second crossbeam 1152c located behind the first crossbeam 1152b. The all-terrain vehicle 100 also includes a body sealing structure 24, which is used to seal the all-terrain vehicle 100. The body sealing structure 24 can be a component on the all-terrain vehicle 100 used to seal in conjunction with the crossbeam 1152. Specifically, at least one of the first crossbeam 1152b and the second crossbeam 1152c is a sheet metal part with multiple sealing surfaces 1152d. The sealing surfaces 1152d can cooperate with the body sealing structure 24 to seal the gap between the sheet metal part and the top beam structure 115. Because sheet metal parts have good ductility, various sealing surfaces 1152d can be machined on the crossbeam 1152 so that the crossbeam 1152 can cooperate with the body sealing structure 24 for sealing, thereby improving the sealing compatibility between the crossbeam 1152 and the body sealing structure 24.

[0173] In one embodiment, the vehicle body sealing structure 24 includes a windshield mechanism 241 and a roof 242. When the first crossbeam 1152b is a sheet metal part, the first crossbeam 1152b forms a first sealing surface 1152g and a front sealing surface 1152h, and the windshield mechanism 241 includes a windshield 2411. The first sealing surface 1152g is located above the first crossbeam 1152b, and the first sealing surface 1152g cooperates with the roof 242 for sealing; the front sealing surface 1152h is located in front of the first crossbeam 1152b, and the front sealing surface 1152h cooperates with the windshield 2411 for sealing.

[0174] Specifically, the windshield mechanism 241 also includes a windshield sealing strip 2412. The windshield sealing strip 2412 is located on the windshield 2411, and when the windshield 2411 is closed, the windshield sealing strip 2412 and the front sealing surface 1152h cooperate to seal. This arrangement helps improve the sealing performance between the windshield 2411 and the front sealing surface 1152h, thereby improving the sealing performance between the windshield 2411 and the first crossbeam 1152b.

[0175] In another embodiment, the vehicle body sealing structure 24 includes a rear windshield mechanism 244 and a roof 242. When the second crossbeam 1152c is a sheet metal part, the second crossbeam 1152c forms a second sealing surface 1152i and a rear sealing surface 1152j, and the rear windshield mechanism 244 includes a rear windshield 2441. The second sealing surface 1152i is located above the second crossbeam 1152c, and the second sealing surface 1152i cooperates with the roof 242 for sealing; the rear sealing surface 1152j is located behind the second crossbeam 1152c, and the rear sealing surface 1152j cooperates with the rear windshield 2441 for sealing.

[0176] Specifically, the rear windshield mechanism 244 also includes a rear windshield sealing strip 2442. The rear windshield sealing strip 2442 is located on the rear windshield 2441. When the rear windshield 2441 is closed, the rear windshield sealing strip 2442 and the rear sealing surface 1152j cooperate to seal. This arrangement improves the sealing performance between the rear windshield 2441 and the rear sealing surface 1152j, thereby improving the sealing performance between the rear windshield 2441 and the second crossbeam 1152c.

[0177] The electrical system 18 also includes a roof harness (not shown). The roof harness is located on the roof structure 115, and the rear support 1123 is located below the roof structure 115. The roof harness allows the wiring of the roof 242 to be connected to the control mechanism of the all-terrain vehicle 100. The roof harness is at least partially routed through the rear support 1123, which helps to conceal the roof harness.

[0178] As shown in Figure 38, in one embodiment, the frame 11 also includes a rear frame 119 located behind the rear pillar 1104, the rear frame 119 being at least partially located above the cargo box 27.

[0179] When the rear frame 119 is in the connected state, the rear frame 119 connects the rear pillar 1104 and the cargo box 27. The rear frame 119 also cooperates with the roof structure 115 for installing the roof 242, so that the all-terrain vehicle 100 becomes a fully covered model with the cargo box 27 covered.

[0180] When the rear frame 119 is in the disassembled state, the rear frame 119 is separated from the rear pillar 1104 and the rear frame 119 is separated from the cargo box 27, so that the all-terrain vehicle 100 becomes a semi-enclosed model with the cargo box 27 exposed.

[0181] Specifically, the rear frame 119 includes a first longitudinal frame 1191, a second longitudinal frame 1192, and a vertical frame 1193. The second longitudinal frame 1192 is located below the first longitudinal frame 1191, and both the first and second longitudinal frames 1191 and 1192 extend substantially along the length of the frame 11. The vertical frame 1193 is connected to the first and second longitudinal frames 1191 and 1192 at both ends along the height direction of the frame 11, so that the vertical frame 1193 can connect the first and second longitudinal frames 1191 and 1192, and the vertical frame 1193 is located behind the first and second longitudinal frames 1191 and 1192. In this embodiment, the first longitudinal frame 1191 is detachably connected to the rear pillar 1104, and the second longitudinal frame 1192 is detachably connected to the cargo box 27. This arrangement allows the rear frame 119 to be detached and installed from the frame 11, enabling the all-terrain vehicle 100 to switch between a semi-enclosed and a fully enclosed model.

[0182] In one implementation, the second longitudinal frame 1192, the vertical frame 1193, and the rear column 1104 are all sheet metal parts. The second longitudinal frame 1192, the vertical frame 1193, and the rear column 1104 cooperate to form a glass sealing surface 1194 for installing the glass. The glass sealing surface 1194 is substantially on the same plane. This arrangement avoids unevenness of the glass sealing surface 1194, which could prevent the glass from being misaligned during assembly, thereby improving the sealing performance between the glass and the glass sealing surface 1194.

[0183] More specifically, the first longitudinal frame 1191, the second longitudinal frame 1192, and the vertical frame 1193 are integrally formed. With this configuration, the integrally formed components do not require assembly, which helps to ensure that the above-mentioned components are on the same plane as the glass sealing surface 1194 of the rear column 1104, thereby improving the sealing performance between the glass and the glass sealing surface 1194.

[0184] As shown in Figures 39 and 40, in one implementation, the canopy 242 includes a front canopy 2423 and a rear canopy 2424 located behind the front canopy 2423. The front canopy 2423 is mounted on the top bar structure 115, and the rear canopy 2424 is mounted on the rear frame 119. When the rear canopy 2424 is in the installed state, the rear frame 119 is connected to the rear pillar 1104, and the rear canopy 2424 cooperates with the front canopy 2423 to seal the all-terrain vehicle 100, thereby improving the sealing performance of the canopy 242. When the rear canopy 2424 is in the disassembled state, the rear frame 119 is separated from the rear pillar 1104. Through the above configuration, the rear canopy 2424 can be disassembled and assembled by removing and assembling the rear frame 119, and the rear canopy 2424 can be disassembled and assembled according to the usage requirements of the all-terrain vehicle 100, thereby improving the ease of disassembly and assembly of the canopy 242. In some embodiments, the front roof 2423 and the roof bar structure 115 can be fixed by fasteners such as bolts, and the rear roof 2424 and the tail frame 119 can also be fixed by fasteners such as bolts.

[0185] As one implementation, the vehicle body sealing structure 24 also includes a seal 246, through which the front roof 2423 and the rear roof 2424 are sealed, thereby improving the sealing performance between the front roof 2423 and the rear roof 2424.

[0186] Specifically, the rear end of the front roof 2423 is at least partially recessed downward to form a water channel 2423a. The water channel 2423a extends along the width direction of the frame 11 and communicates with the outside, thereby forming a drainage structure between the front roof 2423 and the rear roof 2424, so that liquids such as water flowing into the space between the front roof 2423 and the rear roof 2424 can flow out from the water channel 2423a to the outside.

[0187] In this embodiment, the front end of the rear roof 2424 is at least partially located in front of the water channel 2423a and abuts against the front roof 2423, so that the rear roof 2424 and the front roof 2423 can cooperate with each other to form the roof 242 of the all-terrain vehicle 100.

[0188] 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.
