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 (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.

[0003] All-terrain vehicles typically include a frame, body panels, running gear, suspension system, powertrain, transmission system, and door components. The door comprises the door body and a sealing structure, which seals the door to the frame. In existing technology, the sealing structure may misalign with the frame, preventing a proper seal and reducing the door's sealing performance.

[0004] Therefore, how to improve the sealing performance of car doors is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide an all-terrain vehicle with good door sealing performance.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] An all-terrain vehicle includes a frame, body panels, a running gear, a suspension system, a powertrain, front seats, and doors. The body panels are at least partially connected to the frame, the running gear is at least partially located below the frame, the suspension system connects the running gear to the frame, the powertrain is supported by the frame and driven by the running gear, the front seats are supported by the frame, and the doors include a door body and a sealing structure for sealing the gap between the door body and the frame. The frame includes a strut assembly at least partially located behind the front seats. The strut assembly includes an upper strut, a lower strut, a transition strut for connecting the upper and lower struts, and a pillar guard. The pillar guard covers the transition strut and is fixedly connected to the upper and / or lower struts. The pillar guard mates with the upper and lower struts to form a central sealing surface for sealing with the sealing structure, the central sealing surface being substantially on the same plane.

[0008] Furthermore, the vehicle door includes a front door and a rear door, and the sealing structure includes a front door sealing strip and a rear door sealing strip. When the vehicle door body is in the closed state, the front door sealing strip is located between the central sealing surface and the front door, and the rear door sealing strip is located between the central sealing surface and the rear door.

[0009] Furthermore, the column guard plate extends forward to form a sealing extension, which is at least partially located in front of the transition column, and the sealing extension cooperates with the upper column and the lower column to form a central sealing surface.

[0010] Furthermore, the pillar guard plate includes a first guard plate and a second guard plate, which are fixedly connected to form a receiving space for accommodating the adapter pillar. Along the width direction of the frame, the first guard plate and the second guard plate are located on both sides of the adapter pillar.

[0011] Furthermore, the frame and body panels form a cockpit, and along the width direction of the frame, the second skid plate is closer to the cockpit than the first skid plate. The first skid plate, together with the upper and lower pillars, forms a central sealing surface.

[0012] Furthermore, the first guard plate has a first connecting hole and a second connecting hole, and the second guard plate has a third connecting hole and a fourth connecting hole. The axes of the first connecting hole, the second connecting hole, the third connecting hole and the fourth connecting hole all extend along the width direction of the frame. The pillar guard plate also includes a first fastener and a second fastener. The first fastener passes through the first connecting hole, the upper pillar and the third connecting hole, and the second fastener passes through the second connecting hole, the lower pillar and the fourth connecting hole. The pillar guard plate also includes a third fastener, which passes through the second guard plate and is fixedly connected to the first guard plate.

[0013] Furthermore, reinforcing ribs are formed on both the first and second protective plates, and the transition support, upper support, and lower support are all in contact with the reinforcing ribs.

[0014] Furthermore, the adapter support is a hollow structure. The upper end of the adapter support is fitted onto the upper support and fixedly connected to the upper support. A reinforcing member is fixedly connected inside the adapter support. The reinforcing member is located at the lower end of the adapter support and is fixedly connected to the adapter support, the reinforcing member and the lower support by a fastener.

[0015] Furthermore, the reinforcing member includes a first connecting portion and two surrounding portions, the two surrounding portions being connected through the first connecting portion, and each surrounding portion being capable of accommodating a fastener.

[0016] Furthermore, the reinforcing member includes a second connecting portion and two surrounding portions, the two surrounding portions being connected by the second connecting portion, the second connecting portion forming a surrounding structure, each surrounding portion being able to accommodate a fastener, and the surrounding structure being able to accommodate a fastener.

[0017] The central sealing surface formed by the pillar guard plate of the above-mentioned all-terrain vehicle, together with the upper and lower pillars, is basically located on the same plane to improve the fit between the sealing structure and the pillar assembly, thereby improving the sealing performance of the sealing structure and the pillar assembly, and thus improving the sealing performance of the door.

[0034] like Figures 1 to 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, an electrical system 18, and a seat 19.

[0035] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The 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.

[0036] The frame 11 serves as the basic framework of the all-terrain vehicle 100, supporting the body panels 12, the running gear 13, the suspension system 14, the powertrain 15, the electrical system 18, and the 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 a front wheel 131 and a rear wheel 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 wheel 131 or the rear wheel 132. The electrical system 18, supported by the frame 11, is used to display the all-terrain vehicle 100's driving data and control the vehicle's operation. Seat 19 includes front seat 191 and rear seat 192, and is used for the driver and passenger.

[0037] Specifically, the frame 11 includes a front frame 111, a middle frame 112, and a rear frame 113 connected in sequence. Along the length of the 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, the driver's cab 20 being used to provide seating space for the driver and / or passengers.

[0038] In this embodiment, the mid-frame 112 includes a front strut 1121, a strut assembly 1122, and a rear strut 1123. The strut assembly 1122 is located between the front strut 1121 and the rear strut 1123. For the all-terrain vehicle 100, the front strut 1121 is the A-pillar of the all-terrain vehicle 100, the strut assembly 1122 is the B-pillar of the all-terrain vehicle 100, and the rear strut 1123 is the C-pillar of the all-terrain vehicle 100.

[0039] like Figure 3 and Figure 4 As shown, in one embodiment, a support pillar assembly 1122 is disposed between the front seat 191 and the rear seat 192. The support pillar assembly 1122 includes an upper pillar 1122a and a lower pillar 1122b. The lower pillar 1122b is at least partially located below the upper pillar 1122a, and the upper pillar 1122a and the lower pillar 1122b are connected. Specifically, the lower pillar 1122b is at least partially located in front of the upper pillar 1122a, so that an extended space is formed behind the lower 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 and thus improving the comfort of the all-terrain vehicle 100.

[0040] It should be noted that when the seat 19 only includes the front seat 191, the pillar assembly 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, which is conducive to placing items behind the front seat 191, thereby improving the space utilization of the all-terrain vehicle 100. That is, the extended space can increase the space behind the front seat 191.

[0041] Specifically, the pillar assembly 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. Through this arrangement, 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.

[0042] In one embodiment, the adapter support 1122c has a hollow structure, and its upper end is sleeved on the upper support 1122a and fixedly connected to the upper support 1122a. In some embodiments, the upper end of the adapter support 1122c is fixed to the upper support 1122a by welding, thereby improving the connection stability between the adapter support 1122c and the upper support 1122a.

[0043] Specifically, a reinforcing member 1122d is fixedly connected inside the adapter support 1122c. The reinforcing member 1122d is located at the lower end of the adapter support 1122c and is fixedly connected to the adapter support 1122c, the reinforcing member 1122d, and the lower support 1122b by a fastener. The reinforcement member 1122d improves the structural strength of the adapter support 1122c, which in turn improves the connection stability between the lower support 1122b and the adapter support 1122c, thereby improving the structural strength of the support assembly 1122.

[0044] like Figure 3As shown, in one embodiment, the reinforcing member 1122d includes a first connecting portion 1122f and two surrounding portions 1122h. The two surrounding portions 1122h are connected by the first connecting portion 1122f, and each surrounding portion 1122h can accommodate a fastener. With this configuration, when two fasteners are fixedly inserted into the reinforcing member 1122d, each surrounding portion 1122h surrounds one fastener. Through this configuration, the two fasteners can further improve the connection stability between the reinforcing member 1122d and the lower support column 1122b, thereby further strengthening the structural strength of the support column assembly 1122.

[0045] like Figure 4 As shown, in one embodiment, the reinforcing member 1122d includes a second connecting portion 1122g and two surrounding portions 1122h. The two surrounding portions 1122h are connected by the second connecting portion 1122g, and the second connecting portion 1122g forms a surrounding structure 1122k. Specifically, each surrounding portion 1122h can accommodate one fastener, and each surrounding structure 1122k can accommodate one fastener. With this configuration, when three fasteners are fixedly inserted into the reinforcing member 1122d, the two surrounding portions 1122h and the surrounding structure 1122k can each surround one fastener. Through the above configuration, the connection stability between the reinforcing member 1122d and the lower support column 1122b can be further improved by three fasteners compared to two fasteners, thereby further strengthening the structural strength of the support column assembly 1122.

[0046] like Figure 3 and Figure 4 As shown, in another embodiment, at least two reinforcing members 1122d are provided. The two reinforcing members 1122d are defined as a first reinforcing member 1122m and a second reinforcing member 1122n. The first reinforcing member 1122m includes a first connecting portion 1122f and two surrounding portions 1122h. The second reinforcing member 1122n includes a second connecting portion 1122g and two surrounding portions 1122h.

[0047] It should be noted that both reinforcing members 1122d may include a first connecting portion 1122f and two surrounding portions 1122h, or both reinforcing members 1122d may include a second connecting portion 1122g and two surrounding portions 1122h. Therefore, this application does not limit the number and form of the reinforcing members 1122d.

[0048] In one embodiment, the lower end of the adapter post 1122c is at least partially located within the upper end of the lower post 1122b and is fixedly connected to the upper end of the lower post 1122b. With this arrangement, the upper end of the lower post 1122b can be fitted over the lower end of the lower post 1122b, allowing the upper end of the lower post 1122b to limit the position of the adapter post 1122c, thereby facilitating the assembly of the adapter post 1122c and the lower post 1122b. Simultaneously, this fitting method increases the contact area between the lower post 1122b and the adapter post 1122c, thereby improving the connection stability between them.

[0049] Specifically, the upper end of the lower support column 1122b extends upward at least partially to form a first mounting plate 1122i and a second mounting plate 1122j, which are located on both sides of the lower end of the adapter support column 1122c. Through this arrangement, the first mounting plate 1122i and the second mounting plate 1122j can limit the movement of the adapter support column 1122c, thereby improving the accuracy of the adapter support column 1122c and the lower support column 1122b connection, and further improving the connection stability between the adapter support column 1122c and the lower support column 1122b.

[0050] More specifically, fasteners pass through the first mounting plate 1122i, the transition support 1122c, the reinforcing member 1122d, and the second mounting plate 1122j, and are fixedly connected to a connector. In some embodiments, the fastener is a bolt, and the connector is a nut. By bolting through the first mounting plate 1122i, the transition support 1122c, the reinforcing member 1122d, and the second mounting plate 1122j, and fixing them to the nut, a stable connection between the lower support 1122b and the transition support 1122c is achieved.

[0051] In one implementation, the upper support column 1122a, the transition support column 1122c, and the lower support column 1122b are all square tubes. Understandably, the square tubes have a hollow structure, which reduces the cost and structural weight of the upper support column 1122a, the transition support column 1122c, and the lower support column 1122b. Simultaneously, the lightweight square tubes facilitate the assembly of the support column assembly 1122, thereby improving the production efficiency of the all-terrain vehicle 100. Secondly, the square tubes facilitate the formation of a machining plane, which allows for the addition of mounting points to the square tubes, facilitating connections between the square tubes and other components. Furthermore, when the upper support column 1122a, the transition support column 1122c, and the lower support column 1122b, all configured as square tubes, are assembled, relative rotation does not occur, thus improving the connection stability between the transition support column 1122c and the lower support column 1122b of the upper support column 1122a.

[0052] In this application, the upper support column 1122a is at least partially located behind the lower support column 1122b, so that a field of vision that expands the driver's field of vision is formed in front of the upper support column 1122a. This arrangement facilitates the driver's observation of the environment in the cockpit 20 while driving the all-terrain vehicle 100, thereby improving driving safety.

[0053] like Figure 5 and Figure 6 As shown, in one embodiment, the frame 11 includes an upper frame 110 and a lower frame 11b connected to the upper frame 110. Specifically, the running gear 13 is at least partially located below the lower frame 11b, and the suspension system 14 connects the running gear 13 to the lower frame 11b. The all-terrain vehicle 100 includes a door 22 (see reference). Figure 1 The door 22 is supported by and rotatably connected to the upper frame 110. The door 22 includes a door body 221 and a sealing structure 222, which seals the gap between the door body 221 and the upper frame 110. A pillar assembly 1122 is at least partially located behind the front seat 191. The pillar assembly 1122 includes a pillar guard 127 that covers the transition pillar 1122c and protects the transition pillar 1122c. The pillar guard 127 is fixedly connected to the upper pillar 1122a and / or the lower pillar 1122b. The pillar guard 127 mates with the upper pillar 1122a and the lower pillar 1122b to form a central sealing surface 1122e, i.e., the pillar assembly 1122 forms a central sealing surface 1122e, which is used to cooperate with the sealing structure 222 for sealing. The central sealing surface 1122e is basically located on the same plane. This arrangement allows the transition support 1122c of the support assembly 1122 to also form a central sealing surface 1122e with the upper support 1122a and lower support 1122b, thereby improving the flatness of the central sealing surface 1122e on the support assembly 1122. This ensures that the central sealing surface 1122e is basically on the same plane, preventing the sealing structure 222 from being on different planes and thus avoiding misalignment of the sealing structure 222 on the support assembly 1122. This, in turn, improves the fit between the sealing structure 222 and the support assembly 1122, enhancing the sealing performance of both and improving the overall sealing performance of the door 22. Furthermore, the installation of the column guard plate 127 eliminates the need to machine a flat sealing surface on the adapter column 1122c, thereby improving the machining efficiency of the adapter column 1122c and reducing the machining difficulty of the adapter column 1122c.

[0054] As an optional implementation, the sealing structure 222 can be a structure with sealing performance, such as a sealing strip.

[0055] 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. Through the above arrangement, the front door sealing strip 2221 can improve the sealing performance between the front door 2211 and the pillar assembly 1122, and the rear door sealing strip 2222 can improve the sealing performance between the rear door 2212 and the pillar assembly 1122, thereby improving the sealing performance between the door body 221 and the entire frame 11. Meanwhile, the front door 2211 and the rear door 2212 can be sealed by a central sealing surface 1122e. That is, the pillar assembly 1122 can cooperate with the front door sealing strip 2221 and the rear door sealing strip 2222 at the same time to achieve sealing of the front door 2211 and the rear door 2212, which helps to simplify the sealing surface structure of the front door 2211 and the rear door 2212.

[0056] In one embodiment, the column guard plate 127 extends forward to form a sealing extension 1271, which is at least partially located in front of the transition support column 1122c. The sealing extension 1271 cooperates with the upper support column 1122a and the lower support column 1122b to form a central sealing surface 1122e. This arrangement allows the column guard plate 127 to be substantially on the same plane as the upper support column 1122a and the lower support column 1122b, thereby enabling the column guard plate 127, the upper support column 1122a, and the lower support column 1122b to form a central sealing surface 1122e, which facilitates sealing with the sealing structure 222. This configuration allows the sealing extension 1271 located in front of the transition support 1122c to engage with the central sealing surface 1122e formed by the upper support 1122a and lower support 1122b, which in turn seals against the front door sealing strip 2221. Furthermore, the side of the pillar guard plate 127 away from the sealing extension 1271 can engage with the upper support 1122a and lower support 1122b to form another central sealing surface 1122e, which in turn seals against the rear door sealing strip 2222. This configuration allows the pillar guard plate 127 to simultaneously seal against both the front door sealing strip 2221 and the rear door sealing strip 2222, improving the sealing performance between the pillar guard plate 127 and the sealing structure 222.

[0057] As an optional implementation, the pillar guard plate 127 includes a first guard plate 1272 and a second guard plate 1273. The first guard plate 1272 and the second guard plate 1273 are fixedly connected and form a receiving space for accommodating the adapter pillar 1122c. Along the width direction of the frame 11, the first guard plate 1272 and the second guard plate 1273 are located on both sides of the adapter pillar 1122c. This arrangement allows the adapter pillar 1122c to be installed into the receiving space, which facilitates the assembly of the first guard plate 1272 and the second guard plate 1273 with the adapter pillar 1122c, and also improves the protective effect of the first guard plate 1272 and the second guard plate 1273 on the adapter pillar 1122c.

[0058] Specifically, the second skid plate 1273 is closer to the driver's compartment 20 than the first skid plate 1272. This arrangement positions the first skid plate 1272 away from the driver's compartment 20, allowing it to connect with the sealing structure 222 for sealing. Along the width of the frame 11, the first skid plate 1272, in conjunction with the upper support column 1122a and the lower support column 1122b, forms a central sealing surface 1122e. With this arrangement, in this embodiment, only the central sealing surface 1122e needs to be machined on the first skid plate 1272 for connection with the sealing structure 222; the second skid plate 1273 does not need to be machined, thus simplifying the structure of the pillar skid plate 127.

[0059] More specifically, the first guard plate 1272 has a first connecting hole 1272a and a second connecting hole 1272b, and the second guard plate 1273 has a third connecting hole 1273a and a fourth connecting hole 1273b. The axes of the first connecting hole 1272a, the second connecting hole 1272b, the third connecting hole 1273a, and the fourth connecting hole 1273b all extend along the width direction of the frame 11. The pillar guard plate 127 also includes a first fastener 1274 and a second fastener 1275. The first fastener 1274 passes through the first connecting hole 1272a, the upper pillar 1122a, and the third connecting hole 1273a, and the second fastener 1275 passes through the second connecting hole 1272b, the lower pillar 1122b, and the fourth connecting hole 1273b. In some embodiments, both the first fastener 1274 and the second fastener 1275 are bolts, thereby connecting the column guard plate 127 to the upper support column 1122a and the lower support column 1122b via bolts. This configuration can improve the connection stability between the column guard plate 127 and the upper support column 1122a and the lower support column 1122b.

[0060] As an optional implementation, the pillar guard plate 127 further includes a third fastener 1276, which passes through the second guard plate 1273 and is fixedly connected to the first guard plate 1272. In some embodiments, the third fastener 1276 is a screw, and a threaded sleeve is provided on the side of the first guard plate 1272 facing the cockpit 20. The screw passes through the second guard plate 1273 and is connected to the threaded sleeve. This arrangement further enhances the connection stability of the first guard plate 1272 and the second guard plate 1273 through the screw. In addition, in this application, the central sealing surface 1122e on the first guard plate 1272 is located on the side away from the cockpit 20. By providing a threaded sleeve on the side of the first guard plate 1272 facing the cockpit 20, the screw is not exposed on the side of the first guard plate 1272 away from the cockpit 20, thereby avoiding interference from the exposed screw on the central sealing surface 1122e on the first guard plate 1272, which helps to improve the sealing performance between the pillar guard plate 127 and the sealing structure 222.

[0061] In one implementation, reinforcing ribs 1277 are formed on both the first guard plate 1272 and the second guard plate 1273, and the transition support 1122c, the upper support 1122a, and the lower support 1122b are all in contact with the reinforcing ribs 1277. This arrangement allows the pillar guard plate 127 to abut against the transition support 1122c, the upper support 1122a, and the lower support 1122b, thereby improving the structural strength of the pillar guard plate 127. Furthermore, this arrangement also helps to reduce the thickness of the first guard plate 1272 and the second guard plate 1273 along the width direction of the frame 11, thus contributing to a lighter pillar guard plate 127.

[0062] like Figure 7As shown, in one embodiment, the upper frame 110 includes a longitudinal beam 1151, a front pillar 1102, a middle pillar 1103, and a rear pillar 1104. The longitudinal beam 1151 is located above the front pillar 1102, the middle pillar 1103, and the rear pillar 1104. Specifically, the longitudinal beam 1151 extends at least partially along the length of the frame 11. 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. The essentially continuous door sealing surface 1101 refers to the entire door sealing surface 1101 without any breaks, meaning the entire door sealing surface 1101 is uninterrupted. This essentially continuous door sealing surface 1101 prevents breaks in the door sealing surface 1101 that would prevent it from fitting snugly against the sealing structure 222. This improves the fit between the upper frame 110 and the sealing structure 222, thereby enhancing the sealing performance of the upper frame 110 and the sealing structure 222, and ultimately improving the sealing performance of the door 22.

[0063] Secondly, the above-mentioned arrangement allows the longitudinal beam 1151, front pillar 1102, middle pillar 1103, and rear pillar 1104 to form a continuous door sealing surface 1101, thereby improving the sealing performance of the door body 221. Furthermore, the one-piece molded component simplifies the assembly of parts, thereby improving the assembly efficiency of the frame 11 and enhancing the overall strength of the frame 11, thus improving the safety of the all-terrain vehicle 100.

[0064] In this application, the lower frame 11b includes a front support column 11ba, a middle support column 11bb, a rear support column 11bc, and a lower frame body 11bd. The front support column 11ba, the middle support column 11bb, and the rear support column 11bc are all connected to the lower frame body 11bd. Specifically, the front upright 1102 and the front support column 11ba are connected to form a front support column 1121, the middle upright 1103 and the middle support column 11bb are connected to form a support column assembly 1122, and the rear upright 1104 and the rear support column 11bc are connected to form a rear support column 1123.

[0065] like Figures 7 to 9 As shown, 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.

[0066] 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.

[0067] 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. This arrangement can help improve the sealing performance of the door bodies 221 on both sides of the frame 11.

[0068] 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 engaging 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 engaging with the sealing structure 222. This arrangement improves the fit between the sealing structures 222 on both sides and the frame 11 through the first door sealing surface 1101a and the second door sealing surface 1101b, thereby improving the sealing performance of the doors on both sides.

[0069] 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 in the closed state, 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 is used to engage with the front door sealing strip 2221 to form a seal, and the first central sealing surface 1103c is also used to engage with the rear door sealing strip 2222 to form a seal. With this configuration, the upper frame 110 can be sealed to the front door 2211 and the rear door 2212 through a single first central sealing surface 1103c. This eliminates the need to process two sealing surfaces on the upper frame 110 for the front door 2211 and the rear door 2212, which helps to improve the sealing performance of the door body 221 while simplifying the structure of the frame 11.

[0070] In one embodiment, the rear pillar 1104 has 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. With this arrangement, the mating of the aforementioned sealing surfaces allows the door sealing surface 1101 to form a substantially connected surface, thereby improving the sealing performance of the door 22.

[0071] In one implementation, the central support column 11bb has a second central sealing surface 11be. The second central sealing surface 11be and the door sealing surface 1101 form a substantially continuous surface. 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. With this configuration, the sealing between the lower frame 11b and the front door 2211 and the lower frame 11b and the rear door 2212 can be achieved through a single second central sealing surface 11be. This eliminates the need to process two sealing surfaces on the lower frame 11b for the front door 2211 and the rear door 2212, which helps to improve the sealing performance of the door body 221 while simplifying the structure of the frame 11.

[0072] like Figure 7 and Figure 10As shown, 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. Through this arrangement, the crossbeams 1152 can improve the connection stability between the first longitudinal beam 1151a and the second longitudinal beam 1151b, thereby improving the overall connection stability of the frame 11.

[0073] More specifically, the structures of the multiple crossbeams 1152 are basically the same. This arrangement can increase the standardization rate of the crossbeams 1152, thereby enabling mass production of the crossbeams 1152 and reducing production costs. At the same time, the standardization of the crossbeams 1152 also facilitates the replacement of the crossbeams 1152 in the future, thereby improving the maintenance convenience of the all-terrain vehicle 100.

[0074] like Figure 7 and Figure 10 As shown, 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 further improving the universality of the crossbeam 1152, so that the crossbeam 1152 can be installed at any position between the first longitudinal beam 1151a and the second longitudinal beam 1151b, which is conducive to improving the connection convenience between the crossbeam 1152 and the longitudinal beam 1151.

[0075] 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.

[0076] 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 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. With this configuration, mounting points for installing the windshield assembly and the rearview mirror assembly 23 can be integrated on the first crossbeam 1152b, thereby simplifying the mounting point structure of these components. Furthermore, the method of integrating mounting points on the first crossbeam 1152b helps to make the structure of the all-terrain vehicle 100 more compact.

[0077] like Figure 11 and Figure 12 As shown, in one embodiment, the frame 11 includes a top beam structure 115, which includes a crossbeam 1152, 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 for sealing 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. These 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. Through the above arrangement, the sheet metal part facilitates the cooperation of the crossbeam 1152 with other components of the all-terrain vehicle 100 to seal the top beam structure 115. Meanwhile, due to the good ductility of sheet metal parts, various sealing surfaces 1152d can be machined on the crossbeam 1152, so that the crossbeam 1152 can cooperate with the vehicle body sealing structure 24 for sealing, thereby improving the sealing compatibility between the crossbeam 1152 and the vehicle body sealing structure 24. Furthermore, in this embodiment, the sealing surface 1152d on the sheet metal part is a plane, which can avoid the vehicle body sealing structure 24 being located on different planes due to unevenness of the sealing surface 1152d, thereby preventing misalignment of the vehicle body sealing structure 24, and thus improving the sealing performance between the sealing surface 1152d and the vehicle body sealing structure 24, thereby improving the sealing performance of the all-terrain vehicle 100.

[0078] 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 has 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. This arrangement allows the first crossbeam 1152b to seal with the windshield 2411 and the roof 242.

[0079] 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.

[0080] More specifically, the vehicle body sealing structure 24 also includes a first sealing element 243, which is located on the roof 242. When the roof 242 is in the installed state, the first sealing element 243 and the first sealing surface 1152g cooperate to seal. In some embodiments, the first sealing element 243 is a sealing strip or sealing foam. The sealing strip or sealing foam can improve the sealing performance between the roof 242 and the first sealing surface 1152g, thereby improving the sealing performance between the first crossbeam 1152b and the roof 242.

[0081] 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 and seals against the roof 242; the rear sealing surface 1152j is located behind the second crossbeam 1152c, and the rear sealing surface 1152j cooperates with and seals against the rear windshield 2441. This arrangement allows the second crossbeam 1152c to cooperate and seal with the roof 242 and the rear windshield 2441.

[0082] 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.

[0083] More specifically, the vehicle body sealing structure 24 also includes a second seal 245, which is located on the roof 242. When the roof 242 is in the installed state, the second seal 245 cooperates with the second sealing surface 1152i to seal. In some embodiments, the second seal 245 is a sealing strip or sealing foam, which can improve the sealing performance between the roof 242 and the second sealing surface 1152i, thereby improving the sealing performance between the second crossbeam 1152c and the roof 242.

[0084] In one implementation, the first crossbeam 1152b is a pipe, and the second crossbeam 1152c is a sheet metal part. The first crossbeam 1152b is a component of the cab 20; therefore, its strength requirements are high, hence its design as a pipe. The second crossbeam 1152c is not a component of the cab 20; therefore, its strength requirements are lower, allowing it to be a sheet metal part. This facilitates the integration of multiple mounting points and sealing surfaces on the second crossbeam 1152c. This configuration results in higher pipe strength, thereby improving the structural strength of the cab 20 and ultimately enhancing the safety of the all-terrain vehicle 100. Simultaneously, the sheet metal part enhances the functionality of the crossbeam 1152, enabling it to achieve a sealed connection with the roof 242 and the rear windshield 2441.

[0085] It should be noted that when the structural strength of the sheet metal parts meets the structural strength requirements of the cockpit 20, the first crossbeam 1152b can also be a sheet metal part.

[0086] In one implementation, the sheet metal part has multiple mounting points, which are integrally formed with the sheet metal part. This arrangement allows for easy connection between the sheet metal part and other components of the all-terrain vehicle 100.

[0087] Specifically, when the first crossbeam 1152b is a sheet metal part, the mounting points are used to fix the windshield 2411, roof 242, and rearview mirror assembly 23. This arrangement facilitates the connection between the first crossbeam 1152b and the windshield 2411, roof 242, and rearview mirror assembly 23. Simultaneously, due to the good ductility of sheet metal parts, mounting points are easily machined on them, facilitating the integration of the windshield 2411, roof 242, and rearview mirror assembly 23 mounting points onto the sheet metal part. This simplifies the mounting point structure of the all-terrain vehicle 100 and improves the structural compactness of the components.

[0088] In another implementation, when the second crossbeam 1152c is a sheet metal part, the mounting points are used to fix the rear windshield 2441 and the roof 242. This arrangement facilitates the connection between the second crossbeam 1152c and the rear windshield 2441 and the roof 242. Simultaneously, because sheet metal parts have good ductility, mounting points are easily machined on them, which facilitates the integration of the mounting points for the rear windshield 2441 and the roof 242 onto the sheet metal part, thereby simplifying the mounting point structure of the all-terrain vehicle 100 and improving the structural compactness of the components.

[0089] like Figure 13 As shown, in one embodiment, the electrical system 18 also includes a roof support harness 182. The roof support harness 182 is located on the roof support structure 115, and the rear support pillar 1123 is located below the roof support structure 115. The roof support harness 182 allows the wiring of the roof 242 to be connected to the control mechanism of the all-terrain vehicle 100, such as the BCM (Body Control Module). The roof support harness 182 is at least partially routed through the rear support pillar 1123. This arrangement helps to conceal the roof support harness 182, preventing safety hazards caused by its exposure and thus improving the safety of the all-terrain vehicle 100.

[0090] Specifically, the rear strut 1123 has a first through hole 1123d and a second through hole 1123e. The first through hole 1123d and the second through hole 1123e are located near the side of the driver's cabin 20, with the first through hole 1123d located at the upper part of the rear strut 1123 and the second through hole 1123e located at the lower part of the rear strut 1123. Furthermore, the top strut wiring harness 182 at least partially passes through the first through hole 1123d and the second through hole 1123e and is located within the rear strut 1123. In some embodiments, the top strut wiring harness 182 enters the rear strut 1123 from the first through hole 1123d, exits from the second through hole 1123e, and connects to the BCM. This arrangement prevents the top strut wiring harness 182 from being exposed externally, thereby improving the wiring safety of the all-terrain vehicle 100.

[0091] 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.
