Technical Field

[0001] The present application relates to the field of vehicle engineering, and in particular to an all-terrain vehicle. Background Art

[0002] An all-terrain vehicle (ATV) is a vehicle that can navigate complex terrain, making it difficult for ordinary vehicles to maneuver. In China, it's commonly known as a beach buggy. Because its structure is very similar to a motorcycle and many of its components are shared, some people also call it a "four-wheeled motorcycle."

[0003] The fuel tank cap is a crucial component on all-terrain vehicles (ATVs), primarily used to seal the fuel tank and maintain a tight seal. ATVs are often used in complex environments, such as mountainous and hilly terrain, or in areas with complex paths (such as muddy and sandy terrain). Therefore, to prevent the cap from falling off the vehicle, existing fuel tank caps are typically secured with a lock, making the process of opening and closing the cap cumbersome.

The socket and the slide are both located on the flange. When the box cover is fixed to the mounting seat, part of the flange is located in the gap.

[0008] Furthermore, the slideway is spiral-shaped and distributed around the circumference of the insertion channel.

[0009] Furthermore, a strip groove is provided on the side wall of the flange facing away from the cover body, and the groove wall of the strip groove close to the cover body forms a slideway, wherein the strip groove is communicated with the socket.

[0010] Furthermore, a limiting portion is provided on the slide, and the slide includes a first end and a second end arranged opposite to each other. The first end of the slide is connected to the socket, and the second end of the slide is the farthest end of the protrusion moving on the slide. The limiting portion is provided between the first end of the slide and the second end of the slide.

This structure will not be further described in this embodiment.

[0028] In order to clearly illustrate the technical solution of this application, the following is also provided: Figure 1 The front-to-back, left-to-right, and up-to-down directions of the all-terrain vehicle 100 are shown. It should be noted that in the following description of the all-terrain vehicle 100, the length direction of the frame 11 is parallel to the front-to-back direction of the all-terrain vehicle 100, the width direction of the frame 11 is parallel to the left-to-right direction of the all-terrain vehicle 100, and the height direction of the frame 11 is parallel to the up-to-down direction of the all-terrain vehicle 100.

[0029] like Figure 3 As shown, the steering assembly 13 includes a steering wheel 131, a clock spring 132, a first steering column 133, and a second steering column 134. The steering wheel 131 is mounted on the first steering column 133. The first steering column 133 passes through the second steering column 134, and the second steering column 134 is fixed to the vehicle frame 11 (if the steering assembly 13 is fixed to the intermediate frame 112, the second steering column 134 is fixedly connected to the intermediate frame 112). The first steering column 133 is at least partially located within the cockpit 101. The first steering column 133 gradually tilts upward from front to back. The steering wheel 131 is mounted on the rear end of the first steering column 133, and the first steering column 133 rotates with the steering wheel 131.

[0030] The clock spring 132 is mounted on the first direction column 133 and includes a coil core 1321 and a base 1322 fixed relative to the vehicle frame 11. The coil core 1321 is at least partially located between the steering wheel 131 and the base 1322, and is fixedly connected to the steering wheel 131. The base 1322 is at least partially located between the coil core 1321 and the second direction column 134, and is fixedly connected to the second direction column 134. There are various ways to fix the connection, including screws 136, snap connections, or other methods of fixing the two. The coil core 1321 is mounted on the base 1322 and is rotatable relative to the base 1322 along the circumference of the first direction column 133. The coil core 1321 has a terminal 1321a that is electrically connected to an electrical component.

[0031] With this arrangement, during the rotation of the steering wheel 131 , the coil core 1321 rotates along with the steering wheel 131 , and the line connection is reliable, thereby improving the reliability of controlling the steering wheel 131 .

[0032] like Figure 4As shown, the steering wheel 131 has a number of electrical components. The steering wheel 131 includes a main plate 1311, electrical components, and a grip portion 1312 for the driver to grasp. The grip portion 1312 is located on the periphery of the main plate 1311 and is connected to the main plate 1311. The electrical components are mounted on the main plate 1311 and include a start switch 1313, a mode switch 1314, a damper switch 1315, and a volume switch 1316. The start switch 1313, mode switch 1314, damper switch 1315, and volume switch 1316 are all located on the side of the main plate 1311 facing away from the base 1322, that is, on the surface of the main plate 1311 facing the driver. Furthermore, the mode switch 1314 and the start switch 1313 are spaced side by side, and the damper switch 1315 and volume switch 1316 are also spaced side by side. When the steering wheel 131 is not turned, the mode switch 1314 and the start switch 1313 are arranged at intervals along the width direction of the frame 11, and the shock absorber switch 1315 and the volume switch 1316 are arranged at intervals along the width direction of the frame 11, with the shock absorber switch 1315 located above the start switch 1313 and the volume switch 1316 located above the mode switch 1314.

[0033] like Figure 3 and Figure 5 As shown, the second directional column 134 includes a mounting base 1341, an extension sleeve 1342, and a connecting frame 1343. The base 1322 is fixedly connected to the mounting base 1341. The second directional column 134 has an opening 1341a for the first directional column 133 to pass through. The opening 1341a extends through the second directional column 134 from the mounting base 1341 to the connecting frame 1343. The extension sleeve 1342 is located between the mounting base 1341 and the connecting frame 1343. Due to the opening 1341a, the extension sleeve 1342 forms a hollow tubular member. Along the length of the vehicle frame 11, the extension sleeve 1342 is located in front of the steering wheel 131. The connecting frame 1343 is disposed on the outer peripheral wall of the front portion of the extension sleeve 1342 and is connected to the intermediate frame 112. In this embodiment, there are two connecting frames 1343 , and the two connecting frames 1343 are arranged at intervals along the circumference of the extension sleeve 1342 .

[0034] The steering assembly 13 also includes a connecting structure and a switch, and the switch is mounted on the extension sleeve 1342 through the connecting structure. The connecting structure includes a first connecting member 148 and a second connecting member 149. In this embodiment, the switch is a combination switch 138 that integrates the steering and horn. Along the axial direction of the first direction column 133, the connecting frame 1343 is located in front of the combination switch 138. In this embodiment, the combination switch 138 is arranged on the first connecting member 148 or the second connecting member 149. The first connecting member 148 and the second connecting member 149 both have a substantially arc-shaped cross-section. The first connecting member 148 and the second connecting member 149 are connected to each other to form a socket 135 for the extension sleeve 1342 to pass through. The first connecting member 148 and the second connecting member 149 are connected by a fastener in the docking state. The fastener is a screw or bolt with a threaded rod. The corresponding docking surfaces of the first connecting member 148 and the second connecting member 149 are each provided with a threaded hole connected to the fastener.

[0035] The arc-shaped portion of the first connector 148 is defined as the first annular body 1481, and the arc-shaped portion of the second connector 149 is defined as the second annular body. Threaded holes are provided on the mating surfaces of the corresponding ends of the first annular body 1481 and the second annular body. It should be noted that, because the combination switch 138 is required to be installed on the first connector 148, the first connector 148 has an irregular structure, wherein a portion of the first connector 148 is the arc-shaped first annular body 1481. The second connector 149 is used to cooperate with the first connector 148, and no related components are installed on the second connector 149. Therefore, the main body of the second connector 149 constitutes the arc-shaped second annular body.

[0036] The first connector 148 also includes a connecting portion 1482 connected to the first annular body 1481, and the combination switch 138 is mounted on the connecting portion 1482. The connecting portion 1482 includes an inclined section 1482a and a transverse section 1482b. The inclined section 1482a is disposed between the transverse section 1482b and the extension sleeve 1342. One end of the inclined section 1482a is connected to the first annular body 1481, and the other end of the inclined section 1482a extends toward the steering wheel 131, so that the transverse section 1482b is located between the first annular body 1481 and the steering wheel 131. The switch is mounted on the transverse section 1482b.

[0037] like Figure 6As shown, all-terrain vehicle 100 includes a fuel tank 17, which is at least partially mounted on frame 11. In other words, fuel tank 17 is at least partially supported by frame 11. Frame 11 is divided into a front region 114 and a rear region 115 along its length. A longitudinal plane 103 is defined, perpendicular to the length of frame 11 and passing through the longitudinal center of frame 11. Longitudinal plane 103 is located between front region 114 and rear region 115. In this embodiment, fuel tank 17 is located in front region 114 of frame 11. In some embodiments, fuel tank 17 is located in rear region 115 of frame 11. In other embodiments, fuel tank 17 is located at the junction of front region 114 and rear region 115.

[0038] like Figure 6 As shown, the fuel tank 17 includes a tank body 171, a tank cover 172, a mounting base 173, and a connecting rope 174 (see Figure 7 ) and an oil inlet pipe 175. An oil storage chamber (not shown) is defined within the housing 171. The mounting base 173 is connected to the housing 171. In this embodiment, the oil inlet pipe 175 is disposed on the right side of the housing 171. The mounting base 173 is mounted on the oil inlet pipe 175, and the mounting base 173 is connected to the housing 171 via the oil inlet pipe 175.

[0039] like Figures 7 to 9 As shown, the mounting base 173 has an oil inlet channel 1731 and a flange 1732. The oil inlet channel 1731 is connected to the oil storage chamber (not shown). The box cover 172 is arranged on the mounting base 173 and is arranged to rotate relative to the mounting base 173.

[0040] The tank cover 172 includes a cover body 1721, an insert 1722, a protrusion 1723, and a sealing ring 1724. The insert 1722 is mounted on the cover body 1721 and can be inserted into the oil inlet passage 1731. With the insert 1722 engaged with the oil inlet passage 1731, the tank cover 172 rotates around the axis of the insert 1722.

[0041] The protrusion 1723 is provided on the inserting portion 1722. The protrusion 1723 is at least partially located at the periphery of the inserting portion 1722, and a gap 170 is left between the protrusion 1723 and the cover 1721 (see FIG. Figure 7 The flange 1732 is provided on the peripheral wall of the oil inlet passage 1731 and extends along the circumference of the oil inlet passage 1731. In this embodiment, the inner peripheral edge of the flange 1732 defines an insertion passage 1732b for the insertion portion 1722 to pass through.

[0042] A slideway 1733 is provided on the peripheral wall of the oil inlet channel 1731 and extends along the rotation direction of the box cover 172. The protrusion 1723 slides in cooperation with the slideway 1733. The slideway 1733 is spiral and extends along the circumference of the insertion channel 1732b.

[0043] like Figure 9 As shown, the flange 1732 is provided with a socket 1732a for the protrusion 1723 to slide into or out of the slideway 1733. The socket 1732a is located on the mounting seat 173. In this embodiment, the socket 1732a extends outward from the inner edge of the flange 1732. Alternatively, the socket 1732a can be directly provided near the inner edge of the flange 1732, as long as the socket 1732a is located on the flange 1732.

[0044] When protrusion 1723 is inserted into socket 1732a, it can move along slideway 1733. When cover 172 is rotated until protrusion 1723 is located on slideway 1733, a portion of flange 1732 is located within gap 170. In other words, a portion of mounting seat 173 is located within gap 170. When flange 1732 is located within gap 170, cover 172 is constrained to mounting seat 173.

[0045] In this embodiment, there are two protrusions 1723, which are spaced apart along the circumference of the insertion portion 1722. Each protrusion 1723 corresponds to a socket 1732a and a slide 1733. Therefore, there are two sockets 1732a and two slides 1733. In this embodiment, the two sockets 1732a are arranged opposite each other.

[0046] To prevent the two protrusions 1723 from being inserted into the wrong position, thus achieving a foolproof insertion, the mounting base 173 has a guide groove 1732d extending in the locking direction on the wall facing the cover 1721. Guide groove 1732d is provided on the flange 1732 and is located outside the insertion channel 1732b. Furthermore, guide groove 1732d communicates with one of the sockets 1732a. The cover 1721 has a guide member 1221a that mates with guide groove 1732d. When guide member 1221a is located within guide groove 1732d, the protrusion 1723 is located within the corresponding socket 1732a.

[0047] The wall surface of the mounting seat 173 further has a groove 1734 that is recessed in a direction away from the cover body 1721 . The groove 1734 is annular and surrounds the periphery of the oil inlet channel 1731 .

[0048] The oil inlet passage 1731 has an inlet end 1731a. To prevent oil leakage from the oil inlet passage when the tank cover 172 is restrained on the mounting seat 173, a sealing ring 1724 is mounted on the side of the cover 1721 facing the oil inlet passage 1731. The sealing ring 1724 is sleeved around the periphery of the insert portion and corresponds to the oil inlet passage 1731. When the tank cover 172 is restrained on the mounting seat 173, the circumference of the inlet end 1731a abuts against the sealing ring 1724, thereby achieving a sealed connection between the oil inlet passage 1731 and the cover 1721.

[0049] The direction in which protrusion 1723 moves from socket 1732a toward slideway 1733 is defined as the locking direction. When cover 172 is restrained on mounting seat 173, slideway 1733 gradually tilts away from cover body 1721 along the locking direction to reduce the likelihood of cover 172 shaking relative to mounting seat 173 and improve the reliability of cover 172 installation. In this embodiment, a strip groove 1732c is defined on the sidewall of flange 1732 facing away from cover body 1721. Strip groove 1732c gradually tilts away from cover body 1721 along the locking direction. Slideway 1733 is the wall of strip groove 1732c proximal to cover body 1721, which engages with the corresponding edge of socket 1732a to enable protrusion 1723 to slide into or out of slideway 1733. In some embodiments, slideway 1733 is a rib formed on the sidewall of oil inlet passage 1232.

[0050] In order to make the box cover 172 more firmly constrained on the mounting base 173, a limiting portion 1733a is provided on the slide 1733 to limit the protrusion 1723 from continuing to move along the locking direction. When the protrusion 1723 and the limiting portion 1733a are in contact, the side surface of the protrusion 1723 facing the cover body 1721 is against the corresponding position of the slide 1733.

[0051] Exemplarily, the slide 1733 includes a first end and a second end arranged opposite to each other, the first end of the slide 1733 is connected to the socket 1732a, the second end of the slide 1733 is the farthest end of the protrusion 1723 moving on the slide 1733, and the limiting portion 1733a is arranged between the first end of the slide 1733 and the second end of the slide 1733. When the protrusion 1723 moves along the slide 1733 to the second end of the slide 1733, one side of the protrusion 1723 abuts against the second end of the slide 1733, and the other side of the protrusion 1723 abuts against the limiting portion 1733a.

[0052] To prevent the tank cover 172 from being lost when it is removed from the mounting base 173, a first end of a connecting rope 174 is connected to the tank cover 172, and a second end of the connecting rope 174 can be connected to the mounting base 173. In this embodiment, the first end of the connecting rope 174 is located within the insertion portion 1722. The mounting base 173 also includes a mounting plate 1735 disposed on the inner circumferential wall of the oil inlet passage 1731. The mounting plate 1735 has a through-hole for the second end of the connecting rope 174 to pass through. The second end of the connecting rope 174 is provided with an end 1741, and the mounting plate 1735 is always located between the end 1741 and the inlet end 1731a of the oil inlet passage. The presence of the connecting rope 174 ensures that the tank cover 172 is always connected to the mounting base 173 via the connecting rope 174.

[0053] In this embodiment, “fixed connection” is defined as a non-pivotable connection mode, that is, the two components that are set to be fixedly connected cannot undergo relative displacement or relative rotation in the connected state.

[0054] It should be understood that those skilled in the art can make improvements or changes based on the description, and all such improvements and changes should fall within the scope of protection of the claims appended to this application.
