[0059] To make the above objectives, features and advantages of the present application more clear and comprehensible, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different manners according to other alternative embodiments, and those skilled in the art can make similar improvements without departing from the spirit of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0060] As shown in Figure 1 , the present application provides an all-terrain vehicle 100. The all-terrain vehicle 100 is used as a general tool, which can normally travel on beaches, slopes, deserts and other places. In order to clearly describe the structure of the all-terrain vehicle 100, the present application defines the front end, the rear end, the upper side, the lower side, the left side and the right side of the all-terrain vehicle 100 in the following description. Figure 1

[0061] As shown in Figure 1 and Figure 3 , the all-terrain vehicle 100 at least includes a frame assembly 11, a suspension assembly 22, and a wheel assembly 23. The frame assembly 11 is used as a skeleton to carry and connect various components on the all-terrain vehicle 100, and to bear various loads from inside and outside the vehicle. The suspension assembly 22 is installed on the frame assembly 11 and can carry the wheel assembly 23, which is used to buffer the impact force transmitted by the uneven road to the frame assembly 11 and the like, so as to reduce the vibration caused thereby and ensure that the all-terrain vehicle 100 can travel smoothly and stably.

[0062] The suspension assembly 22 includes a front suspension assembly 15 and a rear suspension assembly 16. The wheel assembly 23 includes a front wheel group 17 and a rear wheel group 18. The front suspension assembly 15 is arranged close to the front end of the all-terrain vehicle 100, is installed on the frame assembly 11, and is connected to the front wheel group 17 to transmit the force acting between the front wheel group 17 and the frame assembly 11. In addition, the front suspension assembly 15 can buffer the impact force transmitted by the uneven road to the frame assembly 11 and the like, so as to reduce the vibration caused thereby. The rear suspension assembly 16 is arranged close to the rear end of the all-terrain vehicle 100, is installed on the frame assembly 11, and is connected to the rear wheel group 18 to transmit the force acting between the rear wheel group 18 and the frame assembly 11. In addition, the rear suspension assembly 16 can buffer the impact force transmitted by the uneven road to the frame assembly 11 and the like, so as to reduce the vibration caused thereby.

[0063] As shown in Figure 2 and Figure 4 ​As shown, the frame assembly 11 includes a frame 111 and a body 112. The frame 111 adopts a frame structure and serves as the base to bear various loads inside and outside the vehicle. The front suspension assembly 15 and the rear suspension assembly 16 are respectively mounted on the front and rear ends of the frame 111. Of course, the layout of the front suspension assembly 15 and the rear suspension assembly 16 on the frame 111 can be arranged according to needs, which will not be elaborated here. The body 112 is mounted on the frame 111 and at least partially encloses the frame 111, thereby protecting the parts and components on the frame 111. At the same time, the body 112 also serves as the driver's driving area and a place to accommodate passengers and cargo.

[0064] like Figure 4 As shown, the frame 111 includes a front frame 1111, a middle frame 1112, a rear frame 1113, and a safety unit 1116. The front frame 1111 is located at the front end of the all-terrain vehicle 100 to support or house corresponding front-end components, such as the front suspension assembly 15, headlights, and radiator. The rear frame 1113 is located at the rear end of the all-terrain vehicle 100 to support or house corresponding rear suspension components, such as the rear suspension assembly 16. The middle frame 1112 serves as a connecting and load-bearing component, with the front frame 1111 and rear frame 1113 respectively connected to it. The front frame 1111, middle frame 1112, and rear frame 1113 surround and form an accommodating space 111a. The vehicle body 112 covers the frame 111, and a cabin 1121 is provided on the vehicle body 112. The cabin 1121 serves as a driver's cabin and / or passenger cabin for use by the driver or passengers. The cabin 1121 can be partially embedded in the accommodating space 111a and mounted on the frame 111, thereby allowing the cabin 1121 to have more usable space while the height of the all-terrain vehicle 100 meets the standards. The security unit 1116 is connected to the frame 111 and distributed around the vehicle body 112 to protect the vehicle body 112, the driver, passengers, etc.

[0065] like Figures 5 to 7 As shown, the central frame 1112 serves as the structure bearing the core load of the all-terrain vehicle 100. The central frame 1112 includes first-type beams 1112a and second-type beams 1112b. The first-type beams 1112a and second-type beams 1112b are interconnected, essentially forming a load-bearing structure. In one embodiment, there are multiple first-type beams 1112a, spaced apart and substantially located on the same plane. Here, the plane containing the first-type beams 1112a is designated as plane S. There are also multiple second-type beams 1112b, spaced apart between the first-type beams 1112a. It is understood that the number of first-type beams 1112a can vary, including two, three, or four. Similarly, the number of second-type beams 1112b... Two, three or four unequal rods can be provided. Of course, the specific number of the first type of beams 1112a and the specific number of the second type of beams 1112b can be selected according to actual conditions, which will not be described here.

[0066] In the embodiment, the first type of beams 1112a includes a first cross beam 1112c and a second cross beam 1112d. The second type of beams 1112b includes a first longitudinal beam 1112e and a second longitudinal beam 1112h. Along the front-rear direction of the all-terrain vehicle 100, the first longitudinal beam 1112e is arranged close to the front end, and the second longitudinal beam 1112h is arranged close to the rear end. The first longitudinal beam 1112e includes a first rod 1112f and a second rod 1112g. One end of the first rod 1112f is connected to the first cross beam 1112c, and the other end of the first rod 1112f extends in the direction of the second cross beam 1112d, and the included angle between the first rod 1112f and the plane S is A1, which is set to be greater than or equal to 5° and less than or equal to 15°. One end of the second rod 1112g is connected to the second cross beam 1112d, and the other end of the second rod 1112g extends in the direction of the first cross beam 1112c and is connected to the first rod 1112f. The included angle between the second rod 1112g and the plane S is A2, which is set to be greater than or equal to 5° and less than or equal to 15°. In this way, along the front-rear direction of the all-terrain vehicle 100, the bottom of the middle frame 1112 can be raised upward (away from the driving surface direction). That is, the bottom of the middle frame 1112 is convex upward. In this way, the ground clearance of the all-terrain vehicle 100 at the middle frame 1112 is improved, effectively increasing the passability of the all-terrain vehicle 100 during driving.

[0067] In one embodiment, the angle A1 between the first rod 1112f and the plane S is greater than the angle A2 between the second rod and the plane S. In this way, a better passability can be maintained when the all-terrain vehicle 100 passes through a continuously uneven road. Further, the first type of beam 1112a and the second type of beam 1112b are respectively formed by cutting steel pipes. In this way, the materials and processing are convenient. The first rod 1112f is welded to the first cross beam 1112c, and the second rod 1112g is welded to the second cross beam 1112d. The first rod 1112f and the second rod 1112g are connected by welding. The first rods 1112f in the second type of beam 1112b are arranged parallel to each other, and the second rods 1112g in the second type of beam 1112b are arranged parallel to each other. That is, the second longitudinal beam 1112h includes a third rod 1112i and a fourth rod 1112j. The third rod 1112i is parallel to the first rod 1112f, and one end of the third rod 1112i is connected to the first cross beam 1112c, and the other end of the third rod 1112i extends in the direction of the second cross beam 1112d. The fourth rod 1112j is parallel to the second rod 1112g, and one end of the fourth rod 1112j is connected to the second cross beam 1112d, and the other end of the fourth rod 1112j extends in the direction of the first cross beam 1112c and is connected to the third rod 1112i. As shown in Figure 6 The middle frame 1112 also includes at least two longitudinal reinforcing pipes 1112k and transverse reinforcing pipes 1112l. In this embodiment, two longitudinal reinforcing pipes 1112k are taken as an example to illustrate the positions and installation of the longitudinal reinforcing pipes 1112k. The two longitudinal reinforcing pipes 1112k are arranged at intervals, and the second type of beam 1112b is located between the two longitudinal reinforcing pipes 1112k. One end of each longitudinal reinforcing pipe 1112k is fixed to the first cross beam 1112c, and the other end is fixed to the second cross beam 1112d. The transverse reinforcing pipe 1112l is arranged between the longitudinal beam 1112b and the corresponding longitudinal reinforcing pipe 1112k, and one end of the transverse reinforcing pipe 1112l is connected to the longitudinal beam, and the other end of the transverse reinforcing pipe 1112l is connected to the longitudinal reinforcing pipe 1112k. Thus, the longitudinal reinforcing pipe 1112k, the transverse reinforcing pipe 1112l, the cross beam 1112a, and the longitudinal beam 1112b together form a network-like structure, effectively improving the structural strength and carrying capacity of the entire middle frame 1112.

[0068] As Figure 4As shown, the front frame 1111 also includes a first upright 1111h, and the rear frame 1113 also includes a second upright 1113a. The first upright 1111h and the second upright 1113a are usually referred to as the A-pillar and B-pillar, respectively. The first upright 1111h and the second upright 1113a are used for load-bearing, support, and protection. One end of the first upright 1111h is connected to the first crossbeam 1112c, and the other end of the first upright 1111h extends upward. One end of the second upright 1113a is connected to the second crossbeam 1112d, and the other end of the second upright 1113a extends upward.

[0069] like Figure 8 and Figure 9 As shown, in one embodiment, to improve the structural strength of the connection between the rear frame 1113 and the middle frame 1112, a reinforcing structure 1114 is provided between the rear frame 1113 and the middle frame 1112. The reinforcing structure 1114 includes a first reinforcing rod 1114a, a second reinforcing rod 1114b, and a reinforcing plate 1114c. One end of the first reinforcing rod 1114a is connected to a longitudinal reinforcing tube 1112k on the middle frame 1112, and the other end of the first reinforcing rod 1114a is connected to a second upright 1113a. The rear frame 1113 also includes a support frame 1113y, one end of the second reinforcing rod 1114b is connected to the support frame 1113y, and the other end of the second reinforcing rod 1114b is connected to the second upright 1113a. One end of the reinforcing plate 1114c is connected to the first reinforcing rod 1114a, and the other end of the reinforcing plate 1114c extends towards the rear end of the all-terrain vehicle 100, crosses the second column 1113a, and connects to the second reinforcing rod 1114b. In this way, the reinforcing plate 1114c distributes the force concentrated on the second column 1113a by the first reinforcing rod 1114a and the second reinforcing rod 1114b, thereby avoiding processes such as drilling holes in the second column 1113a and reducing the possibility of local deformation of the second column 1113a. It should be noted that this description only illustrates the connection method of the reinforcing rod at the second column 1113a; the above structure can also be applied to other columns, crossbeams, or longitudinal beams.

[0070] The first reinforcing rod 1114a is welded to the second column 1113a. The second reinforcing rod 1114b is welded to the second column 1113a. The reinforcing plate 1114c is integrally formed by stamping. The reinforcing plate 1114c is welded to the first reinforcing rod 1114a and the second reinforcing rod 1114b respectively. Reinforcing pieces 1114d are provided at both ends of the reinforcing plate 1114c. Each reinforcing piece 1114d abuts against the corresponding reinforcing rod. This increases the contact area between the reinforcing plate 1114c and the first reinforcing rod 1114a and the second reinforcing rod 1114b, thereby improving the connection strength between the reinforcing plate 1114c and the first reinforcing rod 1114a and the second reinforcing rod 1114b.

[0071] As shown in Figure 3 or Figure 4 , the security unit 1116 includes a front bumper 1116a, a side bumper 1116b, and a rear bumper 1116c. The front bumper 1116a is arranged at the front end of the all-terrain vehicle 100 and is distributed around the circumference of the front frame 1111. The front bumper 1116a is connected to the first upright 1111h. The rear bumper 1116c is located at the rear end of the all-terrain vehicle 100 and surrounds the rear frame 1113. In combination Figure 10 , first mounting holes 1116h are formed on the end faces of the two ends of the side bumper 1116b, and first connecting plates 1112c corresponding to the two ends of the side bumper 1116b are arranged on the middle frame 1112. The two ends of the side bumper 1116b are arranged from the outside to the inside of the all-terrain vehicle 100, pass through the vehicle body 112, and extend to the first connecting plates 1112c, and are mounted on the corresponding first connecting plates 1112c to achieve the installation of the side bumper 1116b. Here, the side bumper 1116b is fixed on the first connecting plate 1112c by screws / bolts. The first connecting plate 1112c is made of sheet metal and is formed by stamping to improve the overall structural strength of the first connecting plate 1112c.

[0072] As shown in Figure 2 , the vehicle body 112 includes an interior trim 1122 and an exterior trim 1123. The interior trim 1122 is arranged on the vehicle frame 111 and cooperates with the vehicle frame 111 to form a cabin 1121. In other words, the interior trim 1122 is distributed around the cabin 1121. The exterior trim 1123 is located at the front end, rear end, and side edges of the vehicle frame 111 to shield and protect the front suspension assembly 15, the rear suspension assembly 16, and various electrical components.

[0073] As shown in Figure 2 and Figure 11As shown, the interior parts 1122 include a front fender 1122a, an instrument panel 1122b, a footboard 1122c, a rear fender 1122d, and a seat 1122f. The front fender 1122a is disposed near the front end of the ATV 100, and separates the components at the front end of the ATV 100 from the cabin 1121, and also serves to block stones, sand, and water. The instrument panel 1122b is mounted to the end of the front fender 1122a that is distal from the ground, and serves to carry various instrument devices on the vehicle, such as a display screen, an instrument panel, and the like. The footboard 1122c is mounted to the bottom of the accommodation space 111a, and serves as a carrier plate to carry various components, such as the seat 1122f, and the like, and a position where the feet of the driver or passenger are placed when sitting. The rear fender 1122d is disposed near the rear end of the ATV 100, and separates the components at the rear end of the ATV 100 from the cabin 1121. The rear fender 1122d is spaced apart from the front fender 1122a, and the footboard 1122c is disposed between the rear fender 1122d and the front fender 1122a. In this way, the three together surround the cabin 1121 described above. The seat 1122f is detachably mounted to the footboard 1122c, and serves to seat a passenger or a driver. In an embodiment, the number of seats 1122f is two, and the two seats 1122f are disposed side by side. One of the seats 1122f is disposed to seat a passenger, and the other seat 1122f is disposed as a driver seat. As shown, the seat 1122f is disposed to be inclined with respect to the horizontal direction, and the seat 1122f is disposed to be inclined with respect to the horizontal direction. Figure 11 and Figure 12As shown, a variety of electrical components are generally installed at the instrument panel 1122b, and the electrical components are consumables, so such components need to be repaired and maintained from time to time. When the existing electrical components are repaired, the entire front panel 1122a and / or the instrument panel 1122b needs to be removed as a whole so that the electrical components can be visualized and repaired accordingly. Removing the entire front panel 1122a and / or the instrument panel 1122b is not only cumbersome and inconvenient, but also brings inconvenience to subsequent installation. Therefore, in the present application, an instrument repair opening 1122bh is formed on the instrument panel 1122b and / or the front panel 1122a, and the electrical components or the connection between the electrical components and other components are located at the instrument repair opening 1122bh, that is, the electrical components can be observed or repaired through the instrument repair opening 1122bh. Of course, the instrument repair opening 1122bh can be covered by a second cover plate 1122bi. The second cover plate 1122bi is detachably connected with the instrument panel 1122b or the front panel 1122a. Here, the detachable connection between the second cover plate 1122bi and the instrument panel 1122b or the front panel 1122a can be achieved by threaded connection, clamping connection, etc. When the electrical components need to be repaired, the second cover plate 1122bi can be removed, so that the electrical components can be repaired through the instrument repair opening 1122bh, which is not only convenient but also simple. At the same time, in order to be intuitive and visual, the second cover plate 1122bi can also be provided with a transparent window, through which the state of the electrical components located at the instrument repair opening 1122bh can be observed at any time.

[0074] As shown in Figure 4 and Figure 14 The footboard 1122c is installed on the middle frame 1112, and a bumper repair opening 1122cc is formed on the footboard 1122c. The position of the bumper repair opening 1122cc is aligned with the connection position of the side bumper 1116b and the first connecting plate 1112c. That is, the installation and disassembly of the side bumper 1116b can be operated through the bumper repair opening 1122cc; or in other words, the connection between the side bumper 1116b and the first connecting plate 1112c is arranged around the bumper repair opening 1122cc. In this way, not only can the connection between the side bumper 1116b and the frame 111 be hidden, but also the repair and installation of the side bumper 1116b no longer need to disassemble the entire footboard 1122c and other components, which is not only simple and convenient for repair, but also hidden installation, more beautiful.

[0075] As shown in Figure 15As shown, the third cover plate 1122cd is detachably connected between the third cover plate 1122cd and the foot plate 1122c. Here, the third cover plate 1122cd and the foot plate 1122c can be connected by a threaded member, a buckle, or the like. In this way, the bumper access hole 1122cc can be conveniently opened and closed, and the installation and maintenance of the side bumper 1116b are facilitated. In an embodiment, the foot plate 1122c includes a side surface and a bottom surface, and the bumper access hole 1122cc extends from the bottom surface to the side surface. In this way, the use area of the bumper access hole 1122cc is increased, and a sufficient operating space is provided for maintenance personnel.

[0076] As shown, Figure 2 The outer trim 1123 includes a front trim 1123a, a rear trim 1123b, and a middle trim 1123h. The front trim 1123a covers the outer surface of the front frame 1111. The middle trim 1123h covers the outer surface of the middle frame 1112, and the rear trim 1123b covers the outer surface of the rear frame 1113. In this way, the appearance and safety of the ATV 100 are improved. The front trim 1123a includes at least a front panel 1123aa and an air intake grille 1123ac. The front panel 1123aa covers the upper surface of the front frame 1111 to shield the upper parts of the components mounted on the front frame 1111. The front panel 1123aa is detachably connected to the front frame 1111, so that the front panel 1123aa can be easily disassembled. Thus, the components on the front frame 1111 can be easily maintained. The middle trim 1123h includes a middle side plate 1123ha, which covers the side surface of the middle frame 1112. The two ends of the side bumper 1116b pass through the middle side plate 1123ha, and are connected to the corresponding first connecting plate 1112c.

[0077] As shown, Figure 2 and Figure 16 The front panel 1123aa is provided with a front access hole 1123ae for maintaining the components mounted on the front frame 1111, such as heat exchangers and the like. The front panel 1123aa is provided with a front cover plate 1123ad, which covers the front access hole 1123ae to seal the front access hole 1123ae when maintenance is not required. Here, the front cover plate 1123ad and the front panel 1123aa can be detachably connected by a buckle connection or a threaded member connection. In this way, the front access hole 1123ae can be easily opened and closed. It should be noted that the specific connection method between the front cover plate 1123ad and the front panel 1123aa can be selected according to actual needs and applications, as long as the front cover plate 1123ad can be easily disassembled for maintenance.

[0078] Please refer to Figure 2 The air inlet grille 1123ac is arranged at the front end of the front frame 1111 and is used for protecting the front end face of the all-terrain vehicle 100. The air inlet grille 1123ac can be detachably connected with the front panel 1123aa and / or the front frame 1111. The ratio of the width of the air inlet grille 1123ac to the width of the all-terrain vehicle 100 is greater than or equal to 0.4 and less than or equal to 0.8 along the left-right direction (width direction) of the all-terrain vehicle 100. In this way, the air inlet grille 1123ac has a large air inlet area, which facilitates sufficient heat exchange of the heat exchanger. Moreover, the air inlet grille 1123ac with a large area is arranged, and after the air inlet grille 1123ac is detached, the maintenance of all components on the front end face of the all-terrain vehicle 100 can be basically realized, which makes the maintenance more convenient.

[0079] As shown in Figure 1 , Figure 17 and Figure 23 , the operating assembly 13 includes a gear shift operating mechanism 131, which is mounted on the frame 111 and one end of which is connected with the gear box 122 in the power assembly 12, and the other end of which is located in the cabin 1121 for the driver to operate and shift gears. Of course, the operating assembly 13 includes brake mechanism, steering mechanism and other structures in addition to the above-mentioned gear shift operating mechanism 131. The brake mechanism is used for braking the all-terrain vehicle 100. The steering mechanism is used for the driver to control the driving direction of the all-terrain vehicle 100. The above-mentioned mechanisms cooperate with each other to realize the basic driving operation functions of the all-terrain vehicle 100 as a whole.

[0080] As shown in Figure 17 , the gear shift operating mechanism 131 includes a carrier 1311, a transmission member 1314 and a shift lever 1317. The carrier 1311 is mounted on the frame 111, and one end of the shift lever 1317 is rotatably mounted in the carrier 1311, and the other end of the shift lever 1317 extends into the cabin 1121 to serve as part of the driver's shift operation. One end of the transmission member 1314 is connected with the shift lever 1317, and the other end of the transmission member 1314 extends towards the rear end of the all-terrain vehicle 100 and is connected with the gear box 122, which is used for transmitting the shift command of the shift lever 1317 to the gear box 122. When the shift is needed, the driver operates the shift lever 1317, and transmits the shift signal to the gear box 122 through the transmission member 1314, so as to change the speed or direction of the gear box 122, thereby controlling the power output of the engine 121.

[0081] As shown in Figure 18As shown, the carrier 1311 includes a fifth connecting plate 1312 and a shroud 1313, and the footrest 1122c includes a second mounting hole 1122ce. The fifth connecting plate 1312 can be mounted on the frame 111 by welding or screw connection. At least part of the fifth connecting plate 1312 is located at the second mounting hole 1122ce to be connected with the shift lever 1317. The shroud 1313 is arranged at the second mounting hole 1122ce and connected with the footrest 1122c, so that the footrest 1122c forms an integral whole, and the structure is more compact and beautiful. It can be understood that the fifth connecting plate 1312 is directly mounted on the frame 111, and the shift lever 1317 is directly connected with the fifth connecting plate 1312, so that the existing shift mounting base and other components are omitted, the structure is simple, and the cost is reduced by at least 30%. At the same time, since the fifth connecting plate 1312 and the shift lever 1317 are independent components, the fifth connecting plate 1312 can be fixed on the frame 111 in advance during installation. Thus, when installing the shift lever 1317, the shift lever 1317 can be directly installed on the fifth connecting plate 1312, and there is no need to provide additional sheet metal parts or supports, which is convenient to connect, simple in structure, and low in cost.

[0082] As shown in Figure 17 The transmission member 1314 includes a fourth cable 1315 and an adjuster 1316. One end of the fourth cable 1315 is connected with the transmission 122, and the other end of the fourth cable 1315 is connected with the shift lever 1317. The adjuster 1316 is mounted on the fourth cable 1315 to adjust the tightness of the fourth cable 1315, so as to compensate for the installation error of the shift lever 1317 and the looseness of the fourth cable 1315 after wear. By operating the shift lever 1317, the fourth cable 1315 is pulled to drive the rocker arm of the transmission 122 to move, so as to change the transmission ratio of the transmission 122, and then the change of the power output of the engine 121 is realized, that is, the gear shifting is realized.

[0083] As shown in Figure 20 The footrest 1122c is also provided with a shift maintenance opening 1122cf, and the position of the shift maintenance opening 1122cf corresponds to the position of the adjuster 1316. In other words, the position of the adjuster 1316 is arranged around the shift maintenance opening 1122cf, that is, through the shift maintenance opening 1122cf, the maintenance personnel can maintain and adjust the adjuster 1316 through the shift maintenance opening 1122cf. In this way, the quick maintenance and adjustment of the adjuster 1316 can be realized, and a large number of cover parts can be avoided to be disassembled, and the maintenance is also convenient. Of course, the shift maintenance opening 1122cf here is not limited to the maintenance of the adjuster 1316, but can also be used for the maintenance of all parts in this area.

[0084] As shown in Figures 20 to 22As shown, the side of the footboard 1122c facing the ground is provided with a protrusion 1122cg protruding towards the inside of the cabin 1121, and the second mounting hole 1122ce is formed in the protrusion 1122cg. The shroud 1313 is connected to the protrusion 1122cg and covers the second mounting hole 1122ce. The shift maintenance opening 1122cf is located on the side of the protrusion 1122cg and the bottom surface of the footboard 1122c, thus forming a "L"-shaped shift maintenance opening 1122cf, maximizing the area of the shift maintenance opening 1122cf, and thus facilitating maintenance of the regulator 1316. When maintenance is not required, the shift maintenance opening 1122cf is blocked by the fourth cover plate 1122cj, so that the footboard 1122c is an integral whole during daily use.

[0085] As shown in Figure 21 , the fourth cover plate 1122cj and the footboard 1122c are connected by a detachable structure such as a buckle structure, a threaded structure, etc., so as to facilitate disassembly and assembly of the fourth cover plate 1122cj. In an embodiment, the footboard 1122c is provided with a plug-in port 1122ch and a clamping port 1122ci at the shift maintenance opening 1122cf, and the plug-in port 1122ch and the clamping port 1122ci are oppositely arranged, i.e., the plug-in port 1122ch and the clamping port 1122ci are located on opposite sides of the shift maintenance opening 1122cf. The corresponding fourth cover plate 1122cj is provided with a second plug-in portion 1122ck and a clamping portion 1122cl, the second plug-in portion 1122ck is inserted into the plug-in port 1122ch, and the clamping portion 1122cl is clamped in the clamping port 1122ci, so as to realize detachable connection between the footboard 1122c and the fourth cover plate 1122cj. Of course, the positions of the plug-in port 1122ch and the second plug-in portion 1122ck can be interchanged, and the positions of the clamping port 1122ci and the clamping portion 1122cl can also be interchanged.

[0086] As shown in Figure 22 , in order to realize the integrity of the fourth cover plate 1122cj and the footboard 1122c, the footboard 1122c is provided with a sunken groove 1122cm, and the shift maintenance opening 1122cf is located at the bottom of the sunken groove 1122cm. After the fourth cover plate 1122cj covers the shift maintenance opening 1122cf, the fourth cover plate 1122cj is located in the sunken groove 1122cm, and the surface of the fourth cover plate 1122cj is substantially flush with the surface of the footboard 1122c, so as to form an integral structure of the fourth cover plate 1122cj and the footboard 1122c, and improve the integrity and aesthetic appearance.

[0087] Please refer to Figure 23The fourth cover plate 1122cj and the foot plate 1122c are further provided with a guide structure 1122cn for guiding the installation of the fourth cover plate 1122cj, so that the clamping portion 1122cl can be quickly clamped in the clamping port 1122ci. In an embodiment, the guide structure 1122cn includes a guide portion 1122co, and the foot plate 1122c is provided with a guide groove 1122cp. When the fourth cover plate 1122cj covers the foot plate 1122c, the guide portion 1122co is inserted into the guide groove 1122cp, thereby guiding the clamping portion 1122cl to be clamped into the clamping port 1122ci. Of course, the positions of the guide portion 1122co and the guide groove 1122cp can be interchanged. Meanwhile, the guide structure 1122cn is not limited to the cooperation of the guide portion 1122co and the guide groove 1122cp, but can also be a slope guide and the like.

[0088] In an embodiment, the number of guide grooves 1122cp is at least two, and the relative positions of the two guide grooves 1122cp, and the guide grooves 1122cp are located between the plug-in port 1122ch and the clamping port 1122ci. Meanwhile, the guide grooves 1122cp, the plug-in port 1122ch and the clamping port 1122ci are all located at the bottom of the sink, and are circumferentially arranged around the shift access hole 1122cf.

[0089] As shown in Figure 23 The all-terrain vehicle 100 further includes a power assembly 12 and an air pipe assembly 14. The power assembly 12 is mounted on the frame assembly 11 and serves as a power source to provide corresponding power for the movement of the all-terrain vehicle 100. The air pipe assembly 14 is connected with the power assembly 12 and is used to transport gas to the power assembly 12 and guide the exhaust of gas inside the power assembly 12. The power assembly 12 includes at least an engine 121 and a transmission 122. The engine 121 is mounted on the rear frame 1113 and is used for power output, and the transmission 122 is mounted on one side of the engine 121 to change the speed and torque of the engine 121. The air pipe assembly 14 includes a first air pipe unit 141 and a second air pipe unit 142. The first air pipe unit 141 is connected with the engine 121 and is used to provide gas for the internal combustion of the engine 121 and timely exhaust the gas burned by the fuel. The second air pipe unit 142 is connected with the transmission 122 and is used to transport cooling medium such as water or air for the cooling of the transmission 122.

[0090] As shown in Figure 24 and Figure 25As shown, the first air pipe unit 141 includes a first air inlet pipe 1411, a first air outlet pipe 1412, and an air filter 146. One end of the first air inlet pipe 1411 is connected to the engine 121, and the other end extends upward for air intake. One end of the first air outlet pipe 1412 is connected to the engine 121, and the other end extends along the rear of the ATV 100 to facilitate the exhaust of burned fuel. The air filter 146 is mounted on the first air inlet pipe 1411 and fixed to the frame 111 or the vehicle body 112. The air filter 146 is used to filter the air entering the first air inlet pipe 1411 to meet the requirements of the air entering the engine 121. Also, as shown Figure 2 As shown, the air filter 146 is provided with a wire rack 1461, which can be used to fix brake oil pipes, electrical harnesses, and carbon canister pipes, etc. Thus, the number of openings in the frame 111 and the number of additional supports are reduced, the structural strength is ensured, and the overall cost and weight of the vehicle are reduced. It should be noted that the air filter 146 is a regular maintenance item, and the filter element needs to be cleaned or replaced regularly. The position of the air filter 146 affects whether the filter element can be replaced conveniently and whether dust or sand is brought into the power assembly 12 during replacement, which affects the service life of the power assembly 12. By adjusting the position of the air filter 146 based on the layout of the ATV 100 and overall modification, the air filter 146 can be replaced quickly, conveniently, and without contamination of the filter element during replacement.

[0091] As shown Figure 26 , Figure 26 As shown, the cabin body 1121 is provided with a through filter element maintenance opening 1121b on the cavity wall near the rear end of the ATV 100, and the air filter 146 is located at the filter element maintenance opening 1121b. That is, the filter element maintenance opening 1121b can be used to maintain the air filter 146 and the filter element. In this way, the cabin body 1121 mainly serves as a driver and passenger space, which is the cleanest area in the vehicle compared to the overall vehicle environment. That is, by adjusting the position of the engine 121 and the layout of the first air inlet pipe 1411, the air filter 146 is arranged at the filter element maintenance opening 1121b to reduce the risk of contamination of the filter element during replacement. At the same time, the removal of the corresponding cover of the vehicle body 112 is avoided, and the possibility of bringing dust or sand into the air filter 146 during maintenance is reduced.

[0092] As shown Figure 29As shown, the filter element access opening 1121b is arranged on the rear baffle 1122d, and the seat 1122f is detachably connected to the frame 111 or the vehicle body 112 and can be quickly removed. The filter element access opening 1121b is arranged opposite to the seat 1122f, and the orthographic projection of the filter element access opening 1121b is located on the seat 1122f. Thus, when the air cleaner 146 does not need to be maintained or the filter element does not need to be maintained, the filter element access opening 1121b is covered by the seat 1122f to avoid some dust from entering the filter element access opening 1121b.

[0093] In combination Figures 26 to 32 , along the up-down direction of the all-terrain vehicle, the filter element access opening 1121b is located above the rear frame 1113; and along the front-rear direction of the all-terrain vehicle 100, the filter element access opening 1121b is located at the rear end of the seat 1122f and the front end of the rear cargo box 1123ba. That is, along the front-rear direction of the all-terrain vehicle 100, the filter element access opening 1121b is located between the seat 1122f and the rear cargo box 1123ba. In this way, the highest air filter chamber arrangement height can be obtained to improve the wading depth of the all-terrain vehicle 100.

[0094] As Figure 29 shown, the filter element access opening 1121b is provided with a covering unit 1127, which covers and seals the filter element access opening 1121b. Thus, when the air cleaner 146 does not need to be maintained, the filter element access opening 1121b can be blocked by the covering unit 1127 to avoid dust and the like from entering the air cleaner 146 from the filter element access opening 1121b. It can be understood that, since the filter element access opening 1121b is located inside the cabin 1121, and based on the environment of the cabin 1121, the sealing performance of the covering unit 1127 can be appropriately reduced, thereby reducing the production cost of the covering unit 1127. Even if the sealing of the covering unit 1127 fails, due to the position of the covering unit 1127, the dust prevention of the air cleaner 146 will not fail.

[0095] Please refer to Figure 30The covering unit 1127 includes a first cover 1127a and a second cover 1127e, and the air filter 146 includes a housing 1462 mounted on the first air inlet pipe 1411 and a filter element installed in the housing 1462 to filter the air entering the first air inlet pipe 1411. The housing 1462 is open on a side facing the filter element access opening 1121b (not labeled in the figure), and the filter element is installed in the housing 1462 through the filter element access opening 1121b and the opening. The first cover 1127a covers the opening and is detachably connected with the housing 1462. The second cover 1127e covers the filter element access opening 1121b and is detachably connected with the vehicle body 112 in the cabin 1121, and the second cover 1127e covers the first cover 1127a. When the filter element needs to be replaced, the seat 1122f is moved to provide an operation space for detaching the first cover 1127a and the second cover 1127e, and then the second cover 1127e and the first cover 1127a are detached, so that the filter element is exposed in the maintenance field of view, and then the corresponding maintenance and repair are performed.

[0096] As shown in Figure 31 , the first cover 1127a and the housing 1462 are connected by a quick release structure, so that the first cover 1127a does not need to be disassembled by using additional power tools, making the disassembly of the first cover 1127a and the maintenance and repair of the air filter 146 more convenient and simple. For example, along the vertical direction, one end of the first cover 1127a is provided with a first buckle 1127b, and the other end of the first cover 1127a is provided with a second buckle 1127c, and the second buckle 1127c is located above the first buckle 1127b. Correspondingly, the housing 1462 is provided with a first clamping groove 1463 and a second clamping groove 1464. The first buckle 1127b can be clamped in the first clamping groove 1463, and the second buckle 1127c can be clamped in the second clamping groove 1464, to realize the quick release connection between the first cover 1127a and the housing 1462. When the first cover 1127a needs to be disassembled, only the first buckle 1127b and the second buckle 1127c need to be separated from the first clamping groove 1463 and the second clamping groove 1464, respectively. It can be understood that the positions of the buckle and the clamping groove can be exchanged. That is, the buckle is correspondingly provided on the housing 1462, and the clamping groove is correspondingly provided on the first cover 1127a. Of course, the quick release structure is not limited to the above example, and can also be a threaded structure.

[0097] As shown in Figure 32 and Figure 26As shown, the covering unit 1127 also includes a second limiting portion 1127h and a second elastic buckle 1127i. The second limiting portion 1127h is arranged close to the first buckle 1127b, and one end side of the first cover body 1127a can abut against the second limiting portion 1127h to limit in the front-rear direction of the all-terrain vehicle 100, so as to avoid the first buckle 1127b from being separated from the first clamping groove 1463. The second elastic buckle 1127i is arranged close to the other end of the first cover body 1127a, and the shell 1462 is provided with an elastic buckle shaft 1455. One end of the second elastic buckle 1127i is connected with the elastic buckle shaft 1455. The first cover body 1127a is provided with an elastic buckle groove 1127d on the side away from the shell 1462. Under the action of an external force, the second elastic buckle 1127i can be deformed, so that part of the second elastic buckle 1127i is clamped in the elastic buckle groove 1127d, and the first cover body 1127a is tightly pressed against the shell 1462, that is, the first cover body 1127a is locked. In this way, the vibration of the all-terrain vehicle 100 is avoided, so that the first cover body 1127a is separated from the shell 1462, and the reliability and stability of the connection between the two are improved. At the same time, during maintenance or maintenance, no additional electric tools are needed, and maintenance is more convenient.

[0098] As shown in Figure 32 and Figure 33 shown, the second cover body 1127e and the vehicle body 112 are also connected through a quick release structure, so that the disassembly of the second cover body 1127e and the maintenance and maintenance of the air filter 146 are more convenient and simple without the help of additional electric tools. One end of the second cover body 1127e is provided with a positioning portion 1127f, and the other end of the second cover body 1127e is provided with a deformation portion 1127g. The positioning portion 1127f is arranged close to the first buckle 1127b. The deformation portion 1127g is arranged close to the second elastic buckle 1127i. The hole wall of the filter element maintenance opening 1121b is provided with a first matching portion 1121f matched with the positioning portion 1127f. The first matching portion 1121f matches with the positioning portion 1127f, the deformation portion 1127g deforms under the action of an external force and abuts against the hole wall of the filter element maintenance opening 1121b, so as to realize that the second cover body 1127e blocks the filter element maintenance opening 1121b under the deformation force of the deformation portion 1127g. Of course, a corresponding clamping groove can also be arranged in the filter element maintenance opening 1121b, so that the deformation portion 1127g is clamped in the clamping groove. When the second cover body 1127e needs to be disassembled, only the deformation portion 1127g needs to be pressed to form a gap between the deformation portion 1127g and the inside of the filter element maintenance opening 1121b, so that the second cover body 1127e can be pulled out of the filter element maintenance opening 1121b as a whole to perform corresponding maintenance operation. Of course, the quick release structure is not limited to the above examples, and can also be a threaded structure.

[0099] The following describes the air filter 146 maintenance and repair steps: first, move the seat 1122f to have enough operating space between the seat 1122f and the backstop 1122d; second, the operator presses the deformation part 1127g to make the second cover 1127e and the hole wall of the filter element access hole 1121b disengage, thereby achieving the disassembly of the second cover 1127e; third, the operator lifts the second snap 1127i to make the second snap 1127i disengage from the snap slot 1127d, releasing the locking force of the first cover 1127a; fourth, under the action of external force, the buckle disengages from the corresponding slot, that is, the disassembly of the first cover 1127a is achieved; fifth, the filter element is taken out of the shell 1462, and a new or cleaned filter element is installed in the shell 1462, and then the first cover 1127a and the second cover 1127e are installed in turn, that is, the maintenance and maintenance of the air filter 146 are completed. It can be understood that through the above steps, it can be known that in the maintenance of the air filter 146, any vehicle body 112 accessory does not need to be disassembled, reducing the probability of dust or sand entering the power assembly 12 inside during the replacement process and the possibility of contamination of the filter element; at the same time, the above structure adopts a quick release structure, which does not need to rely on additional electrician tools, and is quick and convenient to replace.

[0100] As shown in Figure 2 The all-terrain vehicle 100 also includes an electrical component assembly 19 and an electronic control unit (ECU) 21. The electrical component assembly 19 is provided on the frame assembly 11 to realize the basic electrical function of the all-terrain vehicle 100. The electronic control unit 21, also known as "vehicle computer", is installed on the frame assembly 11 to monitor various input data (such as brakes, gear shifting, etc.) and various states of vehicle operation (acceleration, skidding, fuel consumption, etc.), and calculate the information transmitted by various sensors according to the pre-designed program. After processing, each parameter is sent to each related actuator to perform various predetermined control functions. Here, the actuator can be the steering assembly 13, the electrical component assembly 19, etc.

[0101] As shown in Figure 26 and Figure 33 Along the front-rear direction of the all-terrain vehicle, the rear of the seat 1122f is provided with an ECU access hole 1121c, which is provided on the cavity wall of the cabin 1121, and the electronic control unit 21 can be maintained through the ECU access hole 1121c. In this way, when the electronic control element 21 needs to be maintained, other large components do not need to be disassembled, and the maintenance convenience is very high. That is, it can be understood that the ECU access hole 1121c is provided through the cavity wall of the cabin 1121 close to the rear end of the all-terrain vehicle 100, and the electronic control element 21 corresponds to the position of the ECU access hole 1121c.

[0102] In an embodiment, the ECU access opening 1121c is provided on the rear panel 1122d and is located between the rear panel 1122d and the seat 1122f. The orthographic projection of the ECU access opening 1121c is located on the seat 1122f along the front-rear direction of the ATV 100. It is appreciated that the seat 1122f in the present application is detachably connected with the frame 111 or the vehicle body 112 and can be quickly removed. Thus, when the ECU access opening 1121c does not need to be opened, it is hidden by the seat 1122f so as to make the cabin 1121 complete and neat. At the same time, in order to avoid impurities, water and the like from entering the cabin 1121 from the ECU access opening 1121c, an ECU cover plate is provided at the ECU access opening 1121c, and the ECU cover plate is connected with the rear panel 1122d through a quick release structure so as to facilitate opening / closing of the ECU access opening 1121c. The ECU cover plate and the rear panel 1122d can be connected through a buckle, a threaded member or the like. In the present embodiment, the ECU cover plate and the rear panel 1122d are connected through a clamping manner. At the same time, the specific structure of the clamping can refer to the clamping manner of the cover plate and the corresponding component at other positions of the present application, which will not be described herein.

[0103] In an embodiment, the ratio of the area of the ECU access opening 1121c to the area of the rear panel 1122d is greater than or equal to 0.2, that is, the area of the ECU access opening 1121c accounts for 20% or more of the area of the rear panel 1122d. In this way, it can be ensured that the ECU access opening 1121c has a large enough operation space for the operator to operate. At the same time, a sunken groove is provided on the rear panel 1122d, the ECU access opening 1121c is located at the bottom of the sunken groove, and when the ECU cover plate covers the ECU access opening 1121c, the ECU cover plate is accommodated in the sunken groove, so that the ECU cover plate and the rear panel 1122d form an integral whole.

[0104] Further, the ECU access opening 1121c and the filter element access opening 1121b are arranged side by side and are located on the same horizontal plane. The seat 1122f is provided in two, and the two seats are also arranged side by side. Along the front-rear direction of the ATV 100, the ECU access opening 1121c is located at the rear side of one of the seats, and the filter element access opening 1121b is located at the rear side of the other seat 1122f.

[0105] As Figure 28As shown, the electric component 19 includes a battery 1922, a diagnostic interface 193, a fuse box 194 and an instrument device 200. The battery 1922 is mounted on the frame 111 for storing electricity to supply power to other electric devices. The diagnostic interface 193 is used to connect an external vehicle detector to detect the parts and systems of the ATV 100 through the vehicle detector to ensure that the vehicle in the service life of the emissions does not exceed the OBD (On Board Diagnostics) regulations. The fuse box 194 is integrated with the vehicle fuse for protecting the safety of each electric device. The instrument device 200 includes various electric instruments, such as an ammeter, a charging indicator light or a voltmeter, an oil pressure gauge, a temperature gauge, a fuel gauge, a speedometer and odometer, an engine speed gauge, etc. The instrument device 200 is mainly used to display the working conditions of the devices during the driving of the ATV 100. The instrument device 200 is also connected with the electronic control unit 21 through the wire harness. And the connection between the instrument device 200 and the electronic control unit 21 can be arranged in the instrument maintenance opening 1122bh, so that through the instrument maintenance opening 1122bh, the maintenance of the connection can also be realized, and the convenience of maintenance is improved. Of course, in the ATV 100, the electric component 19 also includes a starting relay, a rectifier voltage regulator, an illumination unit, a sound device, etc.

[0106] As shown in Figure 33 , the diagnostic interface 193 and the fuse box 194 are mounted on the rear frame 1113 and arranged close to the electronic control unit 21, and located at the ECU maintenance opening 1121c. That is, the diagnostic interface 193 and the fuse box 194 can be operated through the ECU maintenance opening 1121c. Thus, the maintenance of the ECU, the diagnostic interface 193 and the fuse box 194 is realized at the same time, and the maintenance efficiency is effectively improved.

[0107] As shown in Figures 34 to 37As shown, the electrical component assembly 19 further includes a switch device 203 and an electrical connector unit 204. The switch device 203 is connected with the electronic control unit 21 or other electrical devices for controlling the on / off of the corresponding electrical devices. The switch device 203 includes a mode switch 2031, an air conditioner switch (not labeled), a temperature adjustment switch (not labeled), etc. The mode switch 2031, the air conditioner switch, and the temperature adjustment switch are basically installed on the instrument panel 1122b for being operated by the driver and the front passengers. The mode switch 2031, the air conditioner switch, and the temperature adjustment switch are electrically / signal connected with the ECU through a wire harness, thereby controlling a series of functions such as the switching between the two-wheel drive and the four-wheel drive of the ATV 100, the turning on of the air conditioner, the adjustment of the air conditioner temperature, etc. Moreover, the connection between the switch device 203 and the wire harness of each component is arranged around the instrument access hole 1122bh, thereby allowing the switch device 203 to be repaired through the instrument access hole. The electrical connector unit 204 is connected with the storage battery 1922 through a wire harness 2042 and is installed on the vehicle frame 111 for supplying power to the modified parts of the ATV 100, thereby avoiding the damage to the original wire harness of the ATV 100 during the modification.

[0108] It can be understood that, according to the above description of the electrical component assembly 19, at least part of the connections between the electrical component assembly 19 and the electronic control unit 21 are arranged around the instrument access hole 1122bh. In this way, these connections can be repaired through the instrument access hole 1122bh. Of course, the above only shows that these connections can be arranged around the instrument access hole 1122bh. In some other embodiments, these connections can also be arranged around the filter access hole 1121b, the ECU access hole 1121c, etc.

[0109] In an embodiment, as Figure 35As shown, the mode switching switch 2031 includes a two-wheel drive position 2031a, a four-wheel drive position 2031b, and a front-wheel lock position 2031c. The four-wheel drive position 2031b is located between the two-wheel drive position 2031a and the front-wheel lock position 2031c. The two-wheel drive position 2031a enables the two-wheel drive operation of the all-terrain vehicle 100. The four-wheel drive position 2031b enables the four-wheel drive operation of the all-terrain vehicle 100. The front-wheel lock enables the front-wheel lock of the all-terrain vehicle 100. The mode switching switch 2031 includes a housing 2031d, a pressing plate 2031x, a switch shaft 2031t, and a gear lever unit 2031u. The housing 2031d includes a cavity 2031za, a first gear slot 2031e, a second gear slot 2031f, and a third gear slot 2031j. The first gear slot 2031e, the second gear slot 2031f, and the third gear slot 2031j are located in the cavity 2031za. The second gear slot 2031f is located between the first gear slot 2031e and the third gear slot 2031j. The pressing plate 2031x is rotationally connected to the housing 2031d through the switch shaft 2031t. One end of the gear lever unit 2031u is connected to the pressing plate 2031x, and the other end of the gear lever unit 2031u can swing with the pressing plate 2031x and switch between the first gear slot 2031e, the second gear slot 2031f, and the third gear slot 2031j, thereby enabling the mutual switching between the two-wheel drive position 2031a, the four-wheel drive position 2031b, and the front-wheel lock position 2031c.

[0110] Please refer to Figures 35 to 37 The gear lever unit 2031u includes a switching lever 2031v, an elastic member 2031x, and a ball 2031y. One end of the switching lever 2031v is connected to the pressing plate 2031x and can swing in the housing 2031d under the driving of the pressing plate 2031x. The other end of the switching lever 2031v away from the pressing plate 2031x is provided with a fourth mounting hole 2031w. The elastic member 2031x is installed in the fourth mounting hole 2031w. Part of the ball 2031y is located in the fourth mounting hole 2031w and abuts against the elastic member 2031x, and the other end can swing and fall into the first gear slot 2031e, the second gear slot 2031f, or the third gear slot 2031j.

[0111] As Figure 37As shown, the first gear slot 2031e, the second gear slot 2031f, and the third gear slot 2031j are all arc-shaped slots, and the first gear slot 2031e, the second gear slot 2031f, and the third gear slot 2031j are sequentially connected. The second gear slot 2031f includes a first connecting end connected to the first gear slot 2031e, the first gear slot 2031e includes a second connecting end connected to the first connecting end, the first connecting end and the second connecting end intersect and have a first intersection point P and a first included angle β1; the second gear slot 2031f further includes a third connecting end connected to the third gear slot 2031j, the third gear slot 2031j includes a fourth connecting end connected to the third connecting end, the third connecting end and the fourth connecting end intersect and have a second intersection point Q and a second included angle β2; the difference between the first included angle β1 and the second included angle β2 is greater than or equal to 5° and less than or equal to 30°. That is, the slope of the side of the second gear slot 2031f close to the third gear slot 2031j is greater than the slope of the side of the second gear slot 2031f close to the first gear slot 2031e, and the transition between the first gear slot 2031e and the second gear slot 2031f is more gradual than the transition between the second gear slot 2031f and the third gear slot 2031j. In this way, when switching gears, the damping of the switching rod 2031v switching from the second gear slot 2031f to the third gear slot 2031j is greater than the damping of the switching rod 2031v switching from the first gear slot 2031e to the second gear slot 2031f, that is, the force value of each gear switching is different, and the force value required for operation when switching from the four-wheel drive gear to the front-wheel drive lock gear 2031c is increased, avoiding the phenomenon of switching over when switching from the two-wheel drive gear 2031a to the four-wheel drive gear 2031b, directly switching from the two-wheel drive gear 2031a to the front-wheel drive lock gear 2031c, and improving the safety of driving.

[0112] In an embodiment, as shown in Figure 35 along the axis Z direction of the chamber 2031za, the position of the second intersection point Q is relatively higher than the position of the first intersection point P. In this way, in combination with the above-mentioned angle, the stroke of switching from the four-wheel drive gear 2031b to the front-wheel drive lock gear 2031c can be extended, so that the damping of the switching rod 2031v switching from the second gear slot 2031f to the third gear slot 2031j is increased, further avoiding the phenomenon of over-shifting during the switching process.

[0113] Please refer to Figure 37 and Figure 38The second gear slot 2031f comprises a second arc segment 2031g, a first straight segment 2031h and a second straight segment 2031i. One end of the first straight segment 2031h is connected with the first gear slot 2031e, and the other end is connected with the second arc segment 2031g. One end of the second straight segment 2031i is connected with the third gear slot 2031j, and the other end is connected with the second arc segment 2031g. The first gear slot 2031e comprises at least a third straight segment 2031k, and the third gear slot 2031j comprises at least a fourth straight segment 2031z. The third straight segment 2031k intersects with the first straight segment 2031h to form a first included angle β1, and the fourth straight segment 2031z intersects with the second straight segment 2031i to form a second included angle β2. The first included angle β1 is greater than or equal to 120° and less than or equal to 140°, and the second included angle β2 is greater than or equal to 100° and less than or equal to 125°.

[0114] Further, the first straight segment intersects with the plane A1 and forms a third included angle β3, and the second straight segment intersects with the plane A1 and forms a fourth included angle β4. The difference between the fourth included angle β4 and the third included angle β3 is greater than or equal to 5° and less than or equal to 30°. The third included angle β3 is greater than or equal to 45° and less than or equal to 60°, and the fourth included angle β4 is greater than or equal to 55° and less than or equal to 75°. In this way, the slope of the second straight segment 2031i relative to the plane A1 is greater than the slope of the first straight segment 2031h relative to the plane A1. Thus, the force required for the shift lever 2031v to switch from the second gear slot 2031f to the third gear slot 2031j is increased.

[0115] In an embodiment, the third straight segment 2031k intersects with the plane A1 and forms a fifth included angle β5, and the fourth straight segment 2031z intersects with the plane A1 and forms a sixth included angle β6. The fifth included angle β5 is substantially the same as the sixth included angle β6. In this way, the operating force value when the two-wheel drive gear 2031a is switched to the four-wheel drive gear 2031b is substantially equal to the operating force value when the front-wheel drive lock gear 2031c is switched to the four-wheel drive gear 2031b, thereby improving the consistency of the operation.

[0116] As shown in FIG. 6, the shift lever 2031v is in the second gear slot 2031f, and the shift lever 2031v is in the third gear slot 2031j. Figure 39 and Figure 40As shown, the housing 2031d has an output contact 2031l protruding from the outer surface of the housing 2031d. The output contact 2031l is connected to the circuit board on the corresponding switch device 203, such as the circuit board 1981n in the mode switching switch 2031, the circuit board in the air conditioning switch, the circuit board in the temperature adjustment switch, etc. The wire harness 2042 has a butt joint 2031n connected to the output contact 2031l, and the butt joint 2031n is connected to the output contact 2031l, so that the switch device 203 is electrically / signal connected to the electronic control unit 21. The outer surface of the housing 2031d has a connecting cover 2031m circumferentially surrounding the output contact 2031l, which can be integrally formed with the housing 2031d or separately formed. The connecting cover 2031m or the butt joint 2031n is provided with a sealing member 2031q, which can seal the gap between the butt joint 2031n and the connecting cover 2031m after the butt joint 2031n is butted against the output contact 2031l, so that the output contact 2031l is in a relatively sealed state, and the output contact 2031l and the butt joint 2031n are prevented from being short-circuited and ablated by water, etc. At the same time, the connecting cover 2031m also plays a guiding role during the butting process, which is conducive to the connection of the butt joint 2031n and the output contact 2031l, and the assembly is more convenient.

[0117] In an embodiment, the butt joint 2031n is provided with a second receiving groove 2031o and a second insertion groove 2031p, the second receiving groove 2031o is provided with a connecting contact corresponding to the output contact 2031l; the second insertion groove 2031p is arranged around the second receiving groove 2031o, the sealing member 2031q is arranged in the second insertion groove 2031p, and the connecting cover 2031m can be inserted into the second insertion groove 2031p and sealingly connected with the sealing member 2031q. That is, the sealing is realized not only by the sealing member 2031q, but also by covering the butt joint 2031n with the connecting cover 2031m, which increases the sealing path and improves the sealing effect. The second receiving groove 2031o and the second insertion groove 2031p are concentrically arranged. The sealing member 2031q is sleeved on the outer wall of the second insertion groove 2031p. At the same time, the sealing member 2031q is arranged as a rubber sealing ring or a silica gel sealing ring. The outer side wall of the sealing member 2031q is provided with an annular sealing protrusion 2031r, which sealingly abuts against the inner wall of the connecting cover 2031m. Here, the number of the sealing protrusions 2031r is multiple, and the multiple sealing protrusions 2031r are arranged at intervals along the axial direction of the second insertion groove 2031p. In another embodiment, the sealing member 2031q can also be directly arranged on the inner wall of the connecting cover 2031m, and the butt joint 2031n is inserted into the connecting cover 2031m and abuts against the sealing member 2031q.

[0118] As Figures 40 to 42As shown, the electrical connector unit 204 includes the terminal block 2021, the wiring harness 2042, the terminal post 2043 and the power lock 2044. The terminal post 2043 is connected with the battery 1922 through the wiring harness 2042. The power lock 2044 is connected between the terminal block 2021 and the battery 1922, and the opening / closing of the power lock 2044 is linked with the starting / shutting off of the ATV 100. That is, when the ATV 100 is started or powered on, the power lock 2044 is opened. When the ATV 100 is shut off, the power lock 2044 is closed. The terminal post 2043 includes the first type terminal post 2043a and the second type terminal post 2043b. The first type terminal post 2043a is electrically connected with the battery 1922 through the wiring harness 2042. The second type terminal post 2043b is electrically connected to the power lock 2044 through the wiring harness 2042, and is electrically connected to the battery 1922 through the power lock 2044. In this way, the electrical connection between the second type terminal post 2043b and the battery 1922 needs to be controlled by the power lock 2044, so that when the ATV 100 is installed with the modified part (aftermarket part), if the modified part needs to be continuously powered, the modified part can be connected with the corresponding first type terminal post 2043a which is not controlled by the power lock 2044. If the power supply of the modified part needs to be controlled by the starting / shutting off of the ATV 100, the modified part can be connected with the corresponding second type terminal post 2043b which is controlled by the power lock 2044.

[0119] In some embodiments, as Figure 43As shown, the first type of terminal post 2043a includes a first terminal post 2043c and a second terminal post 2043d. The second type of terminal post 2043b includes a third terminal post 2043e. The first terminal post 2043c is connected to the positive terminal of the battery 1922 through the wiring harness 2042, and the second terminal post 2043d is connected to the negative terminal of the battery 1922, so that a continuous power supply loop is formed between the first terminal post 2043c, the second terminal post 2043d, and the positive and negative terminals of the battery 1922. The power lock 2044 is linked to the starting switch of the all-terrain vehicle 100, that is, when the all-terrain vehicle 100 is started, the power lock 2044 is opened, and when the all-terrain vehicle 100 is turned off, the power lock 2044 is also closed. One end of the power lock 2044 is connected to the positive terminal of the battery 1922, and the other end is connected to the third terminal post 2043e through the wiring harness 2042. When the power lock 2044 is opened, the third terminal post 2043e is in communication with the positive terminal of the battery 1922, and when the power lock 2044 is closed, the third terminal post 2043e is disconnected from the positive terminal of the battery 1922. In this way, a power supply loop is formed between the third terminal post 2043e, the power lock 2044, the second terminal post 2043d, and the battery 1922, which is controlled by the power lock 2044; during the process of adding the modification kit to the all-terrain vehicle 100, when the modification kit needs continuous power supply, the modification kit can be connected to the first terminal post 2043c and the second terminal post 2043d. When the power supply of the modification kit needs to be controlled by the start / closure of the all-terrain vehicle 100, the wiring harness of the modification kit can be connected to the second terminal post 2043d and the third terminal post 2043e.

[0120] In other embodiments, as Figure 40 shown, the first type of terminal post 2043a includes a first terminal post 2043c and a second terminal post 2043d, and the second type of terminal post 2043b includes a third terminal post 2043e and a fourth terminal post 2043f, wherein the first terminal post 2043c is connected to the positive terminal of the battery 1922, and the second terminal post 2043d is connected to the negative terminal of the battery 1922 to form a continuous power supply loop; the third terminal post 2043e is connected to the negative terminal of the battery 1922 through the wiring harness 2042, and the fourth terminal post 2043f is connected to the power lock 2044 through the wiring harness 2042 and connected to the positive terminal of the battery 1922 through the power lock 2044. In this way, a power supply loop is formed which is controlled by the power lock 2044. Of course, the number of the first type of terminal post 2043a and the second type of terminal post 2043b can be three, four, or other, and the connection between the terminal post 2043 and the power lock 2044 and the battery 1922 can be a combination of the above two embodiments, or one of the above two embodiments or other forms. The specific choice can be set according to the actual needs, and this is not limited here.

[0121] AsFigure 42 and Figure 40 As shown, the electrical connector unit 204 also includes a fuse box 2045, a terminal cover 2047, and a connection barrier 2046. The fuse box 2045 is located on the corresponding wiring harness 2042 to protect the battery 1992 and minimize the possibility of battery 1922 failing to power. The terminal cover 2047 covers the connector 2021 to protect the terminals 2043, preventing short circuits caused by falling metal objects. Multiple connection barriers 2046 are spaced apart on the connector, isolating adjacent terminals 2043 to prevent interference between the wiring harnesses 2042 of adjacent terminals 2043. Here, the connection barrier 2046 and the connector are integrated.

[0122] In one embodiment, the fuse box 2045 includes a main fuse 2045a and multiple branch fuses 2045b. The main fuse 2045a is located near the positive terminal of the battery 1922. One branch fuse 2045b is located on the wiring harness 2042 connecting the terminal 2043 to the positive terminal of the battery 1922, and another branch fuse 2045b is located on the wiring harness 2042 connecting the terminal 2043 to the power lock 2044. In this embodiment, the main fuse 2045a and the branch fuses 2045b located on the wiring harness 2042 connecting the terminal 2043 to the positive terminal of the battery 1922 are connected in series, thereby achieving dual protection and further preventing the battery 1922 from experiencing power failure.

[0123] like ​ As shown, the wiring harness 2042 includes a first wiring harness 2042a and a second wiring harness 2042c. One end of the first wiring harness 2042a is connected to the terminal block 2043, and the other end of the first wiring harness 2042a has a male terminal 2042b. One end of the second wiring harness 2042c is connected to the battery 1922, and the other end of the second wiring harness 2042c has a female terminal 2042d. The male terminal 2042b and the female terminal 2042d are plugged in, thereby realizing the electrical connection between the terminal block 2021 and the battery 1922. In this way, the wiring harness 2042 on the terminal block 2021 and the battery 1922 are integrated, and the wiring between them is very simple and convenient.

[0124] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
