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 electrical components. The body panels include a front bulkhead, which isolates the frame from the electrical components. In existing technology, the front bulkhead is an assembled component, resulting in poor sealing and allowing air to leak from the front of the all-terrain vehicle into the driver's cabin, reducing driving comfort.

[0004] Therefore, how to improve the driving comfort of all-terrain vehicles is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide an all-terrain vehicle with higher driving comfort.

[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, and an instrument panel. The frame includes a front frame, a mid-frame, and a rear frame connected sequentially. The body panels are at least partially connected to the mid-frame and together form a cab. The body panels include a front bulkhead located in front of the cab and connected to the front frame. The running gear is at least partially located below the front and rear frames. The suspension system connects the running gear to the front and rear frames. The powertrain is supported by the frame and driven by the running gear. The instrument panel is located inside the cab. Along the height of the frame, the highest point of the instrument panel is lower than the highest point of the front bulkhead. The frame also includes a mounting frame. The instrument panel is located on and connected to the mounting frame. The mounting frame is detachably connected to the mid-frame. The front bulkhead is a single piece. When the mounting frame and mid-frame are detached, the front bulkhead can be installed from inside the cab to the front of the cab and connected to the front frame.

[0008] Furthermore, the mid-frame includes a first front strut and a second front strut distributed along the width direction of the frame, and the two ends of the mounting frame are detachably connected to the first front strut and the second front strut, respectively.

[0009] Furthermore, the contact between the mounting frame and the center frame is a surface contact, and the mounting frame and the center frame are detachably connected at the surface contact point by fasteners.

[0010] Furthermore, the front bulkhead includes a bulkhead fixing part connected to the vehicle frame. The contact surface between the mounting frame and the mid-frame is defined as the first surface, and the contact surface between the mid-frame and the mounting frame is defined as the second surface. The bulkhead fixing part is located between the first surface and the second surface, so that the fastener can pass through the mounting frame, the bulkhead fixing part and the mid-frame and be fixed by the connector.

[0011] Furthermore, the mounting frame has a fixing part, which is detachably connected to the front frame.

[0012] Furthermore, the contact between the fixing part and the front frame is a surface contact, and the fixing part and the front frame are detachably connected at the surface contact point by fasteners.

[0013] Furthermore, when the mounting frame and the mid-frame are in a disassembled state, the mid-frame has a mounting channel extending along the length of the frame to the front frame, through which the front bulkhead can pass and connect to the front frame.

[0014] Furthermore, the mounting frame includes transverse tubes extending along the width of the frame and arched tubes connected to the transverse tubes. The transverse tubes are detachably connected to the mid-frame. Panel connection points are provided on both the arched tubes and the transverse tubes. The all-terrain vehicle includes a control panel located in the cab, with the dashboard at least partially located on the control panel. The panel connection points are fixedly connected to the control panel.

[0015] Furthermore, the all-terrain vehicle also includes a steering wheel assembly, with a steering wheel assembly connection point provided on the mounting frame, and the steering wheel assembly connection point is fixedly connected to the steering wheel assembly; the steering wheel assembly connection point is at least partially located between the transverse tube and the arched tube.

[0016] Furthermore, the all-terrain vehicle also includes a power steering system, which is connected to the steering wheel assembly via a transmission. A mechanism mounting bracket is provided on the mounting frame, and the power steering system is fixedly connected to the mechanism mounting bracket.

[0017] The aforementioned all-terrain vehicle allows for assembly of the front bulkhead as a single piece. This avoids reducing the sealing between the front bulkheads due to disassembly, thereby improving the sealing of the front bulkhead and preventing air leakage from the front of the all-terrain vehicle into the driver's cabin, thus enhancing the driving comfort of the all-terrain vehicle.

[0028] 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, and an electrical system 18.

[0029] 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.

[0030] 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, and the electrical system 18. 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 operation of the all-terrain vehicle 100.

[0031] 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.

[0032] 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.

[0033] like Figure 3 and Figure 4As shown, 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, thereby isolating the electrical system 18 on the front frame 111 from the cab 20 and 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, and is used to mount an instrument cluster. 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. 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 assembly of the complete front bulkhead 121 onto the frame 11, avoiding the reduction in sealing between the front bulkhead 121 due to disassembly. This ensures the front bulkhead 121 is a single piece, further improving its sealing and preventing air leakage from the front of the all-terrain vehicle 100 into the cab 20, thereby improving the driving comfort of the all-terrain vehicle 100.

[0034] 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. The front bulkhead 121 can pass through the mounting channel 1125 and connect to the front frame 111. This arrangement facilitates the assembly of the front bulkhead 121 through the mid-frame 112 from inside the driver's cab 20, thereby improving the installation efficiency of the front bulkhead 121. Simultaneously, the disassembled mounting frame 114 does not interfere with the assembly of the front bulkhead 121, thus facilitating the assembly of the complete front bulkhead 121 to the frame 11.

[0035] 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. This arrangement facilitates the assembly and disassembly of the mounting frame 114 onto the first front strut 1121a and the second front strut 1121b. Furthermore, in this embodiment, the first front strut 1121a and the second front strut 1121b form part of the main frame structure of the cockpit 20, thus exhibiting high stability, which in turn improves the structural stability of the mounting frame 114 connected to the first front strut 1121a and the second front strut 1121b.

[0036] 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. In this embodiment, 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.

[0037] like Figure 5 and Figure 6 As shown, in one embodiment, the front bulkhead 121 includes a bulkhead fixing part 1211, which is connected to the frame 11. Specifically, the contact surface between the mounting frame 114 and the mid-frame 112 is defined as the first surface 1141, and the contact surface between the mid-frame 112 and 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. This arrangement allows the mid-frame 112 and the mounting frame 114 to clamp at least a portion of the front bulkhead 121, thereby improving the connection stability of the front bulkhead 121. In some embodiments, the fastener is a bolt, and the connector is a nut. The bolt and nut work together to fix the mounting frame 114, the bulkhead fixing part 1211, and the mid-frame 112.

[0038] like Figure 4 and Figure 7As shown, in one embodiment, the mounting frame 114 has a fixing part 1142, which is detachably connected to the front frame 111. This configuration improves the connection stability of the mounting frame 114, thereby enhancing the installation stability of the dashboard 181. The detachable connection facilitates the installation and removal of the mounting frame 114 from the front frame 111, thus aiding in the assembly of the front bulkhead 121 with the frame 11. In this embodiment, the mounting frame 114 extends at least partially forward to form the fixing part 1142, allowing the mounting frame 114 to be connected to the front frame 111 located at the front of the frame 111 via the fixing part 1142.

[0039] 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 this arrangement, the surface contact connection increases 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, and further enhancing the connection stability between the mounting frame 114 and the frame 11.

[0040] like Figure 4 and Figure 7 As shown, 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.

[0041] In this embodiment, the all-terrain vehicle 100 includes a control panel 122. The control panel 122 is installed inside the driver's cab 20, and the instrument panel 181 is at least partially mounted on the control panel 122 such that the control panel 122 can support the instrument panel 181.

[0042] Specifically, both the arched pipe 1144 and the horizontal pipe fitting 1143 are provided with panel connection points 1145, which are fixedly connected to the control panel 122. This arrangement allows the control panel 122 to be connected to the mounting frame 114, so that the mounting frame 114 can support the instrument.

[0043] 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. This arrangement allows the mounting frame 114 to support the steering wheel assembly 211. In this embodiment, the driver's cab 20 includes a driver's seat and a passenger seat, and the steering wheel assembly 211 is mounted in the driver's seat.

[0044] In this embodiment, the steering system 21 further includes a power steering device 212, which is drively connected to the steering wheel assembly 211 so that the power steering 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 power steering device 212 is fixedly connected to the mechanism mounting bracket 1147. This arrangement allows the mounting frame 114 to support the power steering device 212.

[0045] With the above configuration, mounting points for the power steering device 212, steering wheel assembly 211, control panel 122, and dashboard 181 are integrated on the mounting frame 114. This allows the power steering device 212, steering wheel assembly 211, control panel 122, and dashboard 181 to be integrated onto the mounting frame 114. Simultaneously, it reduces the number of mounting points used to support the power steering device 212, steering wheel assembly 211, control panel 122, and dashboard 181, thereby simplifying the mounting point structure of these components, improving their structural compactness, and increasing the assembly efficiency of the all-terrain vehicle 100. Furthermore, since the mounting frame 114 is a detachable component, the mounting points on the mounting frame 114 can be processed while disassembled, thus improving the processing efficiency and ease of processing the mounting frame 114.

[0046] 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.
