Description

Technical Field

[0001] This invention relates to the field of all-terrain vehicle technology, and in particular to an all-terrain vehicle. Background Technology

[0002] An all-terrain vehicle (ATV) is a vehicle capable of traveling on any terrain. ATVs can be used for off-road driving, racing, and freight transport. The power unit, a crucial component of an ATV, provides the necessary power for its movement. An air intake pipe is connected to the power unit to allow air to enter. An air intake chamber is machined into the vehicle body, with the end of the air intake pipe away from the power unit extending into it. However, existing air intake chambers suffer from poor sealing, low air filtration efficiency, and inadequate waterproofing. Summary of the Invention

[0003] Therefore, it is necessary to provide an all-terrain vehicle with high filtration efficiency, good reliability and low overall cost to address the above-mentioned technical problems.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] An all-terrain vehicle includes: a frame; a body mounted on the frame and forming a cabin; a power unit, at least partially disposed on the frame, and the power unit further including an air inlet and an air outlet; a control assembly mounted on the frame; an air hose assembly including an air inlet pipe and an air outlet pipe, the air inlet pipe being connected to the air inlet and the air outlet pipe being connected to the air outlet; the all-terrain vehicle further includes: an air intake seat, including a mounting hole and an air intake chamber; the air intake chamber has an opening, the side of the body has a mounting cavity, the air intake seat is embedded in the mounting cavity, one end of the air inlet pipe away from the air inlet extends to the air intake seat and extends into the mounting cavity through the mounting hole; a heightened air intake pipe, one end of the heightened air intake pipe can extend into the air intake chamber and is connected to the air inlet pipe, and the other end extends away from the air intake seat in a substantially upward direction.

[0006] In one embodiment, the opening includes a first opening and a second opening, which are arranged adjacent to each other, with the first opening facing the side of the vehicle body and the second opening facing the top of the all-terrain vehicle; a cover plate is provided at the second opening, which covers the second opening, and one end of the heightened air intake pipe can pass through the cover plate and be connected to the air intake pipe.

[0007] In one embodiment, the cover plate is provided with a wall-breaking zone that can communicate with the air inlet and is distributed around the air inlet.

[0008] In one embodiment, the cover plate is a plastic part, and the strength of the cell-breaking zone is less than or equal to the strength of other areas of the cover plate.

[0009] In one embodiment, the air pipe assembly further includes: an adapter pipe, configured as a flexible hose; one end of the adapter pipe is sealed to the air inlet pipe, and the other end of the adapter pipe extends from the mounting hole into the mounting cavity for connection to the heightened air inlet pipe.

[0010] In one embodiment, the adapter pipe includes: a first connecting section located inside the air intake chamber for insertion of the heightened air intake pipe; a third connecting section located outside the air intake chamber and close to the air intake pipe for insertion of the air intake pipe; and a second connecting section located between the first connecting section and the third connecting section and fitted into the mounting hole; wherein the second connecting section is provided with a sealing groove, and the edge of the mounting hole is engaged in the sealing groove.

[0011] In one embodiment, the first connecting section is provided with a flare, which is used to guide the heightened air intake pipe into the first connecting section.

[0012] In one embodiment, the heightened air intake pipe includes: a first section, one end of which is connected to the air intake pipe, and the other end extending vertically upwards; a second section, located at the end of the first section away from the air intake pipe, and connected to the first section; the angle between the axis of the first section and the axis of the second section is greater than or equal to 40° and less than or equal to 140°.

[0013] In one embodiment, the second segment is inclined, and the axis of the second segment is inclined downward relative to the axis of the first segment.

[0014] In one embodiment, a mode switching switch is further included, comprising a two-wheel drive gear, a four-wheel drive gear, and a front-wheel drive lock-up gear, wherein the four-wheel drive gear is located between the two-wheel drive gear and the front-wheel drive lock-up gear; wherein the mode switching switch further comprises: a housing, including a chamber, wherein the chamber includes a first gear slot, a second gear slot, and a third gear slot, wherein the second gear slot is located between the first gear slot and the third gear slot, and wherein the first gear slot, the second gear slot, and the third gear slot are all arc-shaped slots; a button plate, rotatably connected to the housing; and a gear lever unit, one end of which is connected to the button plate, and the other end of which is located in the chamber and can move with the button plate. The gear shifts and switches between the first gear slot, the second gear slot, and the third gear slot. The second gear slot includes a first connecting end connected to the first gear slot, and the first gear slot 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 also includes a third connecting end connected to the third gear slot. The third gear slot 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°.

[0015] In one embodiment, along the axial direction of the chamber, the position of the second intersection point Q is relatively higher than the position of the first intersection point P.

[0016] Compared to existing technologies, the all-terrain vehicle employs a separate air intake seat, with at least a portion of it embedded within a mounting cavity. This ensures that air can only enter the first air intake chamber through an opening in the air intake seat and supply power to the power unit. This not only improves air filtration efficiency but also reduces the processing steps for the rear side panels, saving manufacturing costs. Furthermore, given the high pressure resistance of the air intake seat, the separate design allows for the selection of different materials during manufacturing, enhancing its reliability.

[0047] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0048] like Figure 1 As shown, this application provides an all-terrain vehicle 100. The all-terrain vehicle 100, as a versatile tool, can travel normally on various terrains such as beaches, hillsides, and deserts. To clearly illustrate the structure of the all-terrain vehicle 100, this application... Figure 1The front, rear, upper, lower, left, and right sides of the all-terrain vehicle 100 are defined. The all-terrain vehicle 100 includes a frame assembly 11, a control assembly 13, a front suspension assembly 15, a rear suspension assembly 16, a front wheel set 17, and a rear wheel set 18. The frame assembly 11 serves as the skeleton, supporting and connecting the various components of the all-terrain vehicle 100 and bearing various loads from inside and outside the vehicle. The control assembly 13 is mounted on the frame assembly 11 and is used to control the steering, braking, and speed of the all-terrain vehicle 100. The front suspension assembly 15 is located near the front of the all-terrain vehicle 100, mounted on the frame assembly 11, and connected to the front wheel set 17 to transmit the forces acting between the front wheel set 17 and the frame assembly 11. Furthermore, the front suspension assembly 15 can buffer the impact forces transmitted from uneven road surfaces to the frame assembly 11, etc., to reduce the resulting vibrations and ensure that the all-terrain vehicle 100 can travel smoothly and stably. The rear suspension assembly 16 is located near the rear of the all-terrain vehicle 100. It is mounted on the frame assembly 11 and connected to the rear wheel assembly 18 to transmit the forces acting between the rear wheel assembly 18 and the frame assembly 11. Furthermore, the rear suspension assembly 16 buffers the impact forces transmitted from uneven road surfaces to the frame assembly 11, etc., to reduce the resulting vibrations and ensure that the all-terrain vehicle 100 can travel smoothly and stably.

[0049] like Figure 2 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 sides 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 accordingly as needed, and 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.

[0050] like Figure 3As shown, the frame 111 includes a front frame 1111, a middle frame 1112, and a rear frame 1113. The front frame 1111 is located at the front of the all-terrain vehicle 100 to support or house components located at the front, such as the front suspension assembly 15, headlights, and radiator. The rear frame 1113 is located at the rear of the all-terrain vehicle 100 to support or house components located at the rear, such as the rear suspension assembly 16. The middle frame 1112 serves as a connecting and supporting component, to which the front frame 1111 and the rear frame 1113 are respectively connected. The front frame 1111, middle frame 1112, and rear frame 1113 surround and form an accommodating space 111a. The body 112 covers the frame 111, and a cabin 1121 is provided on the 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 standard.

[0051] 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 beams can be used. Of course, the specific number of Class I beams 1112a and Class II beams 1112b can be selected according to the actual situation, which will not be elaborated here.

[0052] In this embodiment, the first type of beam 1112a includes a first crossbeam 1112c and a second crossbeam 1112d. The second type of beam 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 positioned closer to the front, and the second longitudinal beam 1112h is positioned closer to the rear. 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 crossbeam 1112c, and the other end of the first rod 1112f extends towards the second crossbeam 1112d. The 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 crossbeam 1112d, and the other end of the second rod 1112g extends towards the first crossbeam 1112c and connects to the first rod 1112f. The 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°. Thus, along the front-to-rear direction of the all-terrain vehicle 100, the bottom of the center frame 1112 can be made to bulge upwards (away from the driving surface). That is, the bottom of the center frame 1112 protrudes upwards. This increases the ground clearance of the all-terrain vehicle 100 at the center frame 1112, effectively increasing the passability of the all-terrain vehicle 100 during driving.

[0053] 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. This ensures good passability when the all-terrain vehicle 100 traverses continuously uneven road surfaces. Furthermore, the first type beam 1112a and the second type beam 1112b are respectively fabricated from steel pipes. This facilitates material sourcing and processing. The first rod 1112f is welded to the first crossbeam 1112c, and the second rod 1112g is welded to the second crossbeam 1112d. The first rod 1112f and the second rod 1112g are welded together. The first rods 1112f and 1112g in the second type beam 1112b are arranged parallel to each other, and the second rods 1112g in the second type beam 1112b are also 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 crossbeam 1112c. The other end of the third rod 1112i extends towards the second crossbeam 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 crossbeam 1112d. The other end of the fourth rod 1112j extends towards the first crossbeam 1112c and connects to the third rod 1112i. Figure 6As shown, the central frame 1112 also includes longitudinal reinforcing tubes 1112k and transverse reinforcing tubes 1112l, with at least two longitudinal reinforcing tubes 1112k. In this embodiment, two tubes are used as an example to specifically illustrate the position and installation of the longitudinal reinforcing tubes 1112k. The two longitudinal reinforcing tubes 1112k are spaced apart, and the second type beam 1112b is located between the two longitudinal reinforcing tubes 1112k. One end of each longitudinal reinforcing tube 1112k is fixed to the first transverse beam 1112c, and the other end is fixed to the second transverse beam 1112d. The transverse reinforcing tube 1112l is located between the longitudinal beam 1112b and the corresponding longitudinal reinforcing tube 1112k, with one end of the transverse reinforcing tube 1112l connected to the longitudinal beam and the other end connected to the longitudinal reinforcing tube 1112k. Thus, the longitudinal reinforcing tube 1112k, the transverse reinforcing tube 1112l, the crossbeam 1112a, and the longitudinal beam 1112b together form a mesh-like structure, which effectively improves the structural strength and load-bearing capacity of the entire central frame 1112.

[0054] like Figure 8 As 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.

[0055] like Figure 8 and Figure 9As 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 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.

[0056] 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 plates 1114d are provided at both ends of the reinforcing plate 1114c. Each reinforcing plate 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.

[0057] like Figures 2 to 4 As shown, the vehicle body 112 includes interior trim 1122 and exterior trim 1123. The interior trim 1122 is mounted on the frame 111 and, together with the frame 111, forms the cabin 1121. In other words, the interior trim 1122 is distributed around the cabin 1121. The cabin 1121 has at least one first opening 1121a on one side, through which the driver and passengers can enter and exit the cabin 1121. The exterior trim 1123 is located on the front, rear, and sides of the frame 111, and is used to shield and protect the front suspension assembly 15, the rear suspension assembly 16, and various electrical components.

[0058] Interior components 1122 include a front fender 1122a, an instrument panel 1122b, foot pedals 1122c, a rear fender 1122d, and a seat 1122f. The front fender 1122a is positioned near the front of the all-terrain vehicle 100 to separate components located at the front of the all-terrain vehicle 100 from the cabin 1121 and to block stones, mud, and water. The instrument panel 1122b is mounted on the off-ground end of the front fender 1122a and supports various instrument devices on the vehicle, such as displays and dashboards. The foot pedal 1122c is mounted at the bottom of the accommodating space 111a and serves as a support plate to support various components such as the seat 1122f, as well as a footrest for the driver or passengers. The rear fender 1122d is positioned near the rear of the all-terrain vehicle 100 and separates components located at the rear of the all-terrain vehicle 100 from the cabin 1121. Furthermore, the rear baffle 1122d and the front baffle 1122a are spaced apart, and the foot pedal 1122c is located between the rear baffle 1122d and the front baffle 1122a. In this way, the three together form the aforementioned cabin 1121.

[0059] like Figure 2 and Figure 4 As shown, the exterior 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. This improves the aesthetics and safety of the all-terrain vehicle 100. The front trim 1123a includes at least a front panel 1123aa, a front fender 1123ab, and an air intake grille 1123ac. The front panel 1123aa covers the upper surface of the front frame 1111 to shield the top of components mounted on the front frame 1111. Furthermore, the front panel 1123aa is detachably connected to the front frame 1111, facilitating the removal and installation of the front panel 1123aa. This facilitates the maintenance of components at the front frame 1111. In this embodiment, there are two front fenders 1123ab, corresponding to the number of front wheels, and they are located on the side of the front frame 1111 to cover the side of the front frame 1111 and the corresponding front wheels 171. The central trim 1123h includes a central side plate 1123ha, which covers the side of the central frame 1112.

[0060] The rear trim 1123b includes a cargo box 1123ba, rear side panels 1123bc, and a taillight panel 1123bd. The cargo box 1123ba carries cargo and is mounted above the rear frame 1113. There are two rear side panels 1123bc, located on either side of the cargo box 1123ba, which can also serve as rear mudguards to prevent mud, sand, etc., from being splashed by the rear wheels. Alternatively, in one embodiment, the rear trim 1123b may also include a rear mudguard 1123bi, which vertically covers the rear wheel 181 to prevent water, mud, sand, etc., from being splashed by the rear wheel 181. In this case, the rear side panels 1123bc function as covers. The rear side panels 1123bc are detachably connected to the rear frame 1113. Therefore, by removing the rear side panels 1123bc, the components in this area can be repaired, improving the convenience of maintenance. The taillight panel 1123bd is located at the rear of the cargo box 1123ba and is used to mount the taillights of the all-terrain vehicle 100.

[0061] like Figure 10 As shown, the all-terrain vehicle 100 also includes an air hose assembly 14. The air hose assembly 14 is connected to the power assembly 12 and is used to supply or exhaust gases to provide the necessary medium for cooling and combustion of the power assembly 12, and to promptly remove gases from fuel combustion. In one embodiment, the air hose assembly 14 includes a first air hose unit 141 and a second air hose unit 142. The first air hose unit 141 is connected to the engine 121 and is used to supply gases for internal combustion in the engine 121 and to promptly remove gases from fuel combustion. The second air hose unit 142 is connected to the transmission 122 and is used to supply a cooling medium, such as water or air, for cooling the transmission 122.

[0062] The first air intake unit 141 includes a first intake pipe 1411 and a first exhaust pipe 1412. A first intake chamber 1125 is provided on the side of the vehicle body 112 and is in communication with the outside atmosphere. One end of the first intake pipe 1411 is connected to the air intake port of the engine 121, and the other end extends into the first intake chamber 1125 on the vehicle body 112. Gas can enter the first intake pipe 1411 through the first intake chamber 1125. One end of the first exhaust pipe 1412 is connected to the exhaust port of the engine 121, and the other end extends to the rear side of the vehicle body 112 to facilitate the discharge of exhaust gas after fuel combustion. The second air duct unit 142 includes a second air intake pipe 1421 and a second air outlet pipe 1422. A second air intake chamber 1126 is provided on the side of the vehicle body 112 and is in communication with the outside atmosphere. One end of the second air intake pipe 1421 is connected to the air intake port of the transmission 122, and the other end of the second air intake pipe 1421 extends into the second air intake chamber 1126. Cooling gas can enter the second air intake pipe 1421 through the second air intake chamber 1126 to cool the transmission 122. One end of the second air outlet pipe 1422 is connected to the air outlet of the transmission 122, and the other end is aligned with the first air outlet pipe 1412, carrying away some of the heat from the first air outlet pipe 1412.

[0063] Combination Figure 2 and Figure 4 As shown, the first air intake chamber 1125 and the second air intake chamber 1126 are both located on the side of the vehicle body 112, and vertically, they are positioned relatively far from the bottom of the all-terrain vehicle 100 to ensure sufficient height. It is understood that the all-terrain vehicle 100, as a commonly used recreational vehicle, often wades through deep water. The first air intake chamber 1125 and the second air intake chamber 1126 are positioned sufficiently high on the vehicle body 112. When the vehicle is wading through water, the sufficiently high first air intake chamber 1125 effectively ensures the air supply required by the engine 121, and the sufficiently high second air intake chamber 1126 effectively ensures the cooling air supply required by the transmission 122. This increases the wading depth and usability of the all-terrain vehicle 100, preventing water from entering the engine 121 and causing vehicle damage.

[0064] For example, the first air intake chamber 1125 is located on the left side of the vehicle body 112 and near the rear side of the vehicle body 112, while the second air intake chamber 1126 is located on the right side of the vehicle body 112 and near the rear side of the vehicle body 112. Furthermore, vertically, the first air intake chamber 1125 and the second air intake chamber 1126 are positioned at the same height on the side of the vehicle body 112. This arrangement allows for dispersed air intake for the engine 121 and the transmission 122, preventing water from entering the first and second air intake pipes 1421 simultaneously during wading. Simultaneously, placing the first air intake chamber 1125 and the second air intake chamber 1126 on both sides of the vehicle body 112 fully utilizes the space of the vehicle body 112, improving the rationality of the layout.

[0065] Between the front and rear sides of the all-terrain vehicle 100, a first air intake chamber 1125 is arranged near the rear side of the cabin 1121 and near the front side of the rear wheel assembly 18. That is, both the first air intake chamber 1125 and the second air intake chamber 1126 are located between the cabin 1121 and the rear wheel assembly 18. The structures of the first air intake chamber 1125 and the second air intake chamber 1126 can be the same or different, depending on the actual situation. In this embodiment, to save on overall processing and manufacturing processes, the structures of the first air intake chamber 1125 and the second air intake chamber 1126 are set to be the same. Therefore, the following description focuses on the first air intake chamber 1125 to describe the overall air intake method of the power assembly 12. Furthermore, structures that can be installed on the first air intake chamber 1125 can also be installed on the second air intake chamber 1126.

[0066] like Figures 12 to 14 As shown, the frame assembly 111 also includes an air intake seat 143. A mounting cavity 1121g corresponding to the air intake seat 143 is formed on the side of the vehicle body 112 near the rear. The air intake seat 143 is partially or completely embedded in the mounting cavity 1121g. In one embodiment, there are two air intake seats 143, one with a first air intake chamber 1125 and the other with a second air intake chamber 1126. The left and right sides of the vehicle body 112 each include a mounting cavity 1121g. One air intake seat 143 is at least partially embedded in the left mounting cavity 1121g, and the other air intake seat 143 is at least partially embedded in the right mounting cavity 1121g. The rear wheel assembly 18 includes a left rear wheel 181 and a right rear wheel 182. Based on the positions of the first air intake chamber 1125 and the second air intake chamber 1126, we know that the air intake seat 143 is located between the chassis 1121 and the rear wheel assembly 18. One of the air intakes 143 is located between the left rear wheel 181 and the cabin 1121, and the other air intake 143 is located between the right rear wheel 182 and the cabin.

[0067] The intake seat 143 is also provided with a third mounting hole 1431 that communicates with the first intake chamber 1125. The axis of the third mounting hole 1431 is basically parallel to the vertical axis. The end of the first intake pipe 1411 away from the engine 121 extends into the first intake chamber 1125 through the third mounting hole 1431 and is installed on the intake seat 143. The first intake chamber 1125 is provided with a fourth opening 1432 on the side corresponding to the vehicle body 112. The fourth opening 1432 communicates with the outside atmosphere, that is, the outside atmosphere enters the first intake chamber 1125 through the fourth opening 1431 to realize the normal intake of the first intake pipe 1411.

[0068] like Figure 11 As shown, a baffle 1433 is provided at the fourth opening 1432, and a filter hole 1434 is provided on the baffle 1433. External air enters the first intake chamber 1125 after being filtered through the filter hole 1434, thus removing impurities from the external air and ensuring the cleanliness of the air inside the first intake chamber 1125. At least one layer of filter screen (not shown in the figure) is provided on the inner side of the baffle 1433 or inside the filter hole 1434. This filter screen further filters the air entering the filter hole, making the air entering the first intake chamber 1125 cleaner and extending the service life of the engine 121. It should be noted that the baffle 1433 can be connected to the intake seat 143 or the vehicle body 112 via a detachable structure such as bolts, screws, or clips, facilitating the removal of the baffle and the cleaning and maintenance of the inside of the first intake chamber 1125.

[0069] like Figure 12 and Figure 14As shown, the bottom of the first air intake chamber 1125 is provided with a third protrusion 1125a, and the third protrusion 1125a protrudes from the bottom of the first air intake chamber 1125. A third mounting hole 1431 is formed on the third protrusion 1125a, and the orientation of the third mounting hole 1431 is inconsistent with the orientation of the fourth opening 1432. The first air intake pipe 1411 extends into the first air intake chamber 1125 or communicates with the first air intake chamber 1125 through the third mounting hole 1431 on the third protrusion 1125a. In this way, the position of the third mounting hole 1431 is higher than the bottom of the mounting chamber 1121g, and the orientation is different from that of the fourth opening 1432. That is, it is equivalent to raising the air intake position of the first air intake pipe 1411 and making the air intake port of the first air intake pipe 1411 offset from the fourth opening 1432. When the all-terrain vehicle 100 is in operation or being cleaned, if water or other impurities enter the first air intake chamber 1125 through the fourth opening 1432, the third protrusion 1125a acts as a barrier and guide to prevent water or other impurities from entering the first air intake pipe 1411 and to guide the water away from the inlet of the first air intake pipe 1411. This parallel blocking and guiding achieves a double barrier against water and other impurities at the inlet of the first air intake pipe 1411, effectively enhancing the waterproof and dustproof effect of the first air intake pipe 1411. This reduces the probability of engine 121 being damaged due to the entry of environmental fluids or impurities, thus reducing the failure rate of the engine 121 and improving the safety of the all-terrain vehicle 100.

[0070] Along the vertical direction, the third protrusion 1125a extends upward, and the axis of the third mounting hole 1431 coincides with the vertical direction, that is, the third mounting hole 1431 faces vertically, and the orientation of the fourth opening 1432 is perpendicular to the axis of the third mounting hole 1431. Thus, when water or other impurities enter the first air intake chamber 1125 through the fourth opening 1432, they will first come into contact with the side of the third protrusion 1125a facing the fourth opening 1432, and flow into the bottom of the first air intake chamber 1125 under the guidance or obstruction of the side of the third protrusion 1125a, and then flow out of the first air intake chamber 1125 through the assembly gap between the air intake seat 143 and the body 112.

[0071] like Figure 12 and Figure 14As shown, the end face of the third protrusion 1125a away from the bottom of the first air intake chamber 1125 is set as an inclined surface. For ease of explanation, this inclined surface is referred to here as the third inclined surface 1125b. The third mounting hole 1431 is located on the third inclined surface 1125b. The third inclined surface 1125b slopes from the side of the third protrusion 1125a near the fourth opening 1432 towards the side of the third protrusion 1125a away from the fourth opening 1432. Furthermore, along the vertical direction, the side of the third inclined surface 1125b near the fourth opening 1432 is relatively higher than the side of the third inclined surface 1125b away from the fourth opening 1432. In this way, within the space of the first air intake chamber 1125, the side of the third protrusion 1125a facing the fourth opening 1432 can be positioned highest, effectively blocking water or other impurities when they enter through the fourth opening 1432.

[0072] Please refer to Figure 12 To facilitate the outflow of water from the first air intake chamber 1125, the bottom surface of the first air intake chamber 1125 is also designed as a slope. For ease of explanation, this slope is referred to here as the fourth slope 1125c. Along the direction from the rear to the front of the all-terrain vehicle 100, the fourth slope 1125c is inclined towards the ground (i.e., the lower side). When water or other substances enter the first air intake chamber 1125, the water first flows towards the bottom of the first air intake chamber 1125 due to the obstruction and diversion effect of the third protrusion 1125a. Then, guided by the fourth slope 1125c, the water in the first air intake chamber 1125 can be discharged quickly and timely, reducing the possibility of water entering the first air intake pipe 1411 due to water accumulation in the first air intake chamber 1125.

[0073] like Figure 15 As shown, the first air intake unit 141 also includes a heightened air intake pipe 144, which vertically raises the air intake position of the first air intake pipe 1411, allowing the all-terrain vehicle 100 to achieve a higher air intake position. This ensures that the engine 121 assembly remains watertight even in deep water, maintaining normal operation. It should be noted that the heightened air intake pipe 144 is an auxiliary component (aftermarket part). During normal use, the first air intake pipe 1411 does not need to be heightened; that is, the heightened air intake pipe 144 is not required. When the all-terrain vehicle 100 needs to travel in deep water (such as on sandy beaches or in rivers), the heightened air intake pipe 144 can be directly connected to the first air intake pipe 1411 to raise its air intake. This not only makes it convenient to use but also simplifies installation.

[0074] Combination Figure 12The heightened intake pipe 144 has one end that extends into the first intake chamber 1125 and connects to the first intake pipe 1411. The other end of the heightened intake pipe 144 extends away from the intake seat and is generally upward. A fifth opening 1125d is provided on the first intake chamber 1125. The fifth opening 1125d is adjacent to the fourth opening 1432, and the orientation of the fifth opening 1125d is the same as the orientation of the third mounting hole 1431. Simultaneously, a fifth cover plate 1125e is provided at the fifth opening 1125d, and the fifth cover plate 1125e covers the third mounting hole 1431 and the air inlet of the first intake pipe 1411 to prevent water or other impurities (stones, debris, etc.) from entering the engine 121 from the air inlet. That is, during normal use, the fifth opening 1125d is normally sealed to prevent the air inlet of the first intake pipe 1411 from being exposed to the outside.

[0075] Furthermore, the fifth cover plate 1125e is provided with an air inlet that connects to the first air inlet pipe 1411, and a wall-breaking zone 1124f is distributed around the air inlet. The force-bearing capacity of the wall-breaking zone 1124f is less than that of other areas of the fifth cover plate 1125e. When it is necessary to increase the air intake height, a simple tool such as a hammer can be used to directly break the wall-breaking zone 1124f to form a through hole. Then, one end of the heightened air intake pipe 144 can be inserted into the first air intake chamber 1125 through the through hole and sealed to the first air intake pipe 1411. In this way, not only can the complicated procedure of increasing the air intake height be eliminated, but the structure is also simple. At the same time, the position and orientation of the third mounting hole 1431 are also considered. After the wall breaking zone 1124f is damaged, the first air intake pipe 1411 can be directly inserted into the first air intake chamber 1125 and connected to the first air intake pipe 1411. This straight-line installation is easy to align and connect, and does not require professional maintenance personnel to modify. Drivers or ordinary people can complete the height increase requirement, and the operation is easy.

[0076] The fifth cover plate 1125e is made of plastic, and the strength of the wall-breaking zone 1124f is less than or equal to the strength of other areas of the fifth cover plate 1125e. This makes the wall-breaking zone 1124f easier to break than other areas, simplifying the installation of the heightened intake pipe 144. In one embodiment, the wall thickness of the wall-breaking zone 1124f is less than the wall thickness of other areas of the fifth cover plate 1125e, so that the pressure-bearing capacity of the wall-breaking zone 1124f is less than that of other areas. In another embodiment, a groove is formed on the inner wall of the fifth cover plate 1125e to form the wall-breaking zone 1124f. That is, forming the wall-breaking zone 1124f by setting a groove is not only simple in structure and easy to process, but also has lower manufacturing costs. Of course, the wall-breaking zone 1124f can also be formed on the fifth cover plate 1125e by other methods.

[0077] like Figure 16 and Figure 17 As shown, to facilitate the connection between the heightened intake pipe 144 and the first intake pipe 1411, an adapter pipe 145 is provided between the heightened intake pipe 144 and the first intake pipe 1411. One end of the adapter pipe 145 extends into the third mounting hole 1431 and connects to the first intake pipe 1411, while the other end of the adapter pipe 145 is located in the first intake chamber 1125 and connects to the heightened intake pipe 144. In one embodiment, the adapter pipe 145 is a rubber tube with a sealing groove 1455 formed on its peripheral wall. One end of the rubber tube passes through the third mounting hole 1431 and is fitted and sealed between it and the first intake pipe 1411. The edge of the third mounting hole 1431 is engaged in the sealing groove 1455, so that the adapter pipe 145 is sealed to the intake seat 143. The other end of the rubber tube is sealed and fitted to the heightened intake pipe 144. Understandably, based on the material properties of the rubber hose, it possesses sealing characteristics, not only facilitating the connection but also improving the sealing effect between the connecting pipe 145 and both the first air intake pipe 1411 and the raised air intake pipe 144. Simultaneously, the rubber hose exhibits a certain degree of deformation, providing a buffering and vibration-absorbing effect as the connection point between the first air intake pipe 1411 and the raised air intake pipe 144 on bumpy driving environments. Here, the rubber hose can be made of rubber or silicone, etc.

[0078] The adapter pipe 145 includes a first connecting section 1451, a second connecting section 1452, and a third connecting section 1453. The second connecting section 1452 is located between the first connecting section 1451 and the third connecting section 1453. The first connecting section 1451 is located inside the first air intake chamber 1125, and the third connecting section 1453 is located outside the first air intake chamber 1125 and close to the first air intake pipe 1411. The second connecting section 1452 is embedded in the third mounting hole 1431 to bridge the first connecting section 1451 and the second connecting section 1452. Furthermore, a sealing groove 1455 is formed on the outer wall of the second connecting section 1452; the edge of the third mounting hole 1431 is engaged within the sealing groove 1455. Meanwhile, the ends of the first connecting section 1451 and the third connecting section 1453 away from the second connecting section 1452 are both flared. These flares serve a guiding function to facilitate the connection between the first intake pipe 1411 and the heightened intake pipe 144 and the adapter pipe 145, respectively. Here, the second connecting section 1452 is corrugated. On the outer circumferential surface of the second connecting section 1452, the aforementioned sealing groove 1455 is formed between two adjacent corrugations.

[0079] Furthermore, clamps 1454 are fitted onto the outer periphery of both the adapter pipe 145 and the heightened air intake pipe 144, and onto the outer periphery of both the adapter pipe 145 and the heightened air intake pipe 144, respectively. These clamps 1454 tighten the connection, achieving a stable connection while improving sealing performance. It should be noted that the above example illustrates one connection method between the first air intake pipe 1411 and the heightened air intake pipe 144. In other embodiments, the first air intake pipe 1411 and the heightened air intake pipe 144 can also be connected by snap-fit, threads, or other methods. The outer peripheral surfaces of the first connecting section 1451 and the third connecting section 1453 each have corresponding positioning grooves. The clamps 1454 are fitted into the corresponding positioning grooves, tightening the connection between the first connecting section 1451 and the heightened air intake pipe 144, and between the first air intake pipe 1411 and the third connecting section 1453.

[0080] like Figure 18 and Figure 19 As shown, the heightened intake pipe 144 includes a first section 1441 and a second section 1442. One end of the first section 1441 extends into the first intake chamber 1125 through a through hole on the fifth cover plate 1125e and connects to the adapter pipe 145. The other end of the first section 1441 extends away from the intake seat 143 and generally upward. One end of the second section 1442 is connected to the end of the first section 1441 away from the first intake chamber 1125. The other end of the second section 1442 serves as an inlet, and the axis of the second section 1442 is set at an angle to the axis of the first section 1441. It should be explained that water and impurities always tend to move vertically downwards due to gravity. By making the axis of the second section 1442 at an angle to the axis of the first end, that is, by setting the axis of the air inlet at an angle to the vertical direction, water or other impurities are prevented from directly entering the heightened intake pipe 144 from the inlet under the influence of gravity. The angle between the axis of the second segment 1442 and the axis of the first segment 1441 is greater than or equal to 40° and less than or equal to 140°, and the end of the second segment 1442 away from the first segment 1441 extends towards the front of the all-terrain vehicle 100. This allows the second segment 1442 to tilt towards the frame 111 or the ground, reducing the possibility of water or other impurities entering and improving the safety of the engine 121 components. In one embodiment, the angle between the axis of the second segment 1442 and the axis of the first segment 1441 is greater than or equal to 60° and less than or equal to 140°. It is understood that within the above angle range, the intake height of the intake pipe 144 can be optimally increased, and water, dust, etc., can also enter from the second segment 1442. Preferably, the angle between the axis of the second segment 1442 and the axis of the first segment 1441 is greater than or equal to 80° and less than or equal to 110°.

[0081] In one embodiment, the second segment 1442 is inclined, and its axis is inclined downward relative to the axis of the first segment 1441. The end of the second segment 1442 away from the first segment 1441 is closed, and an air inlet 1446 is formed on the side of the second segment 1442 facing the ground. A filter 1447 is provided at the air inlet 1446 to filter the medium entering the second segment 144 from the air inlet 1446, ensuring the cleanliness of the air entering the heightened air intake pipe 144. The axis of the air inlet 1446 can be substantially parallel to the axis of the first segment 1441, or it can be inclined relative to it. This ensures that the air inlet 1446 is always oriented towards the first air intake pipe 1411 and is in the same direction as the gravity of water or other impurities, preventing water or other impurities from entering the heightened air intake pipe 144 from the air inlet 1446. Meanwhile, with the second section 1442's axis set at an acute angle to the first section 1441's axis, under the inclined guidance of the second section 1442, even if a small amount of water or other impurities enter the second section 1442 through the air inlet 1446, they will be stored at the end of the second section 1442 away from the first section 1441 under the guidance of the second section 1442. When the water or impurities accumulate to a certain extent, they can be discharged or removed through the air inlet 1446.

[0082] like Figure 13 and Figure 14 As shown, the heightened air intake pipe 144 also includes a third section 1443, which is located between the first section 1441 and the second section 1442. The third section 1443 is a curved section, that is, the third section is set in an arc shape, and the bending direction of the third section 1443 is basically the same as the bending direction of the second pillar 1113a, so as to improve the coordination and integrity between the heightened air intake pipe 144 and the vehicle body 112 after the all-terrain vehicle 100 is heightened. A first positioning step 1444 is formed between the third section 1443 and the first section 1441. After the first section 1441 is inserted into the first air intake cavity 1125, the first positioning step 1444 abuts against the fifth cover plate 1125e, realizing the positioning of the heightened air intake pipe 144, and also preventing the first section 1441 from being excessively inserted into the first air intake cavity 1125 or the adapter pipe 145.

[0083] The raised air intake pipe 144 is provided with a third connecting part 1445. After the raised air intake pipe 144 is connected to the first air intake pipe 1411, the third connecting part 1445 is connected to the vehicle body 112. This achieves dual positioning of the raised air intake pipe 144 to prevent the connection between the raised air intake pipe 144 and the first air intake pipe 1411 from failing due to vibration of the all-terrain vehicle 100 or external forces. Here, the connection between the third connecting part 1445 and the vehicle body 112 can be achieved by using a quick-release structure 1122e such as bolts, clips, or clamps. In one embodiment, the third connecting part 1445 is provided on the third section 1443.

[0084] like Figure 19 As shown, the heightened air intake pipe 144 also includes a second fixing plate 1448. One end of the second fixing plate 1448 is fixed to the second section 1442, and the other end is used to connect to the upper body 112. Combined with the third connecting part 1445, triple positioning of the heightened air intake pipe 144 can be achieved, effectively improving the stability of the installation of the heightened air intake pipe 144. In one embodiment, the second fixing plate 1448 and the second section 1442 are detachably connected. Therefore, the position between the second fixing plate 1448 and the heightened air intake pipe 144 can be adjusted. This allows for adjustment of the connection position between the heightened air intake pipe 144 and the body 112, improving the flexibility of the installation of the heightened air intake pipe 144. Here, the second fixing plate 1448 and the second section 1442 can be detachably connected via bolts, clips, or other structures.

[0085] like Figure 20 As shown, the all-terrain vehicle 100 also includes an electrical component 19 and an electronic control unit 21. Both the electrical component 19 and the electronic control unit 21 are mounted on the frame assembly 11, and the electrical component 19 is at least partially electrically / signally connected to the electronic control unit 21 to realize the basic electrical functions of the all-terrain vehicle 100. The electronic control unit 21, abbreviated as ECU (Electronic Control Unit), is also known as the "vehicle computer." It monitors various input data (such as braking, gear shifting, etc.) and various vehicle operating states (acceleration, slippage, fuel consumption, etc.), and calculates the information transmitted by various sensors according to a pre-designed program. After processing, it sends the parameters to the relevant actuators, such as the electrical component 19, to execute various predetermined control functions.

[0086] In one implementation, such as Figure 20As shown, the electrical components 19 include instrumentation devices 200 and switching devices 203. Instrumentation devices 200 include various electrical gauges, such as ammeters, charging indicator lights or voltmeters, oil pressure gauges, temperature gauges, fuel gauges, speedometers, odometers, and engine tachometers. Instrumentation devices 200 are mainly used to display the operating status of relevant devices while the all-terrain vehicle 100 is in motion. Sound-emitting devices 201 are mainly used to emit sounds to provide prompts or warnings. Switching devices 203 include a mode switching switch 2031, an air conditioning switch (not shown), and a temperature adjustment switch (not shown). The mode switching switch 2031, air conditioning switch, and temperature adjustment switch are basically installed on the instrument panel 1122b for easy operation by the driver and front passenger. The mode switching switch 2031, air conditioning switch, and temperature adjustment switch are all electrically / signally connected to the electronic control unit 21 via wiring harness 2042, thereby controlling a series of functions of the all-terrain vehicle 100, such as switching between two-wheel drive and four-wheel drive, turning on the air conditioning, and adjusting the air conditioning temperature.

[0087] like Figures 21 to 24 As shown, the mode switching switch 2031 includes a two-wheel drive gear position 2031a, a four-wheel drive gear position 2031b, and a front-wheel drive lock position 2031c. The four-wheel drive gear position 2031b is located between the two-wheel drive gear position 2031a and the front-wheel drive lock position 2031c. The two-wheel drive gear position 2031a enables the all-terrain vehicle 100 to operate in two-wheel drive mode. The four-wheel drive gear position 2031b enables the all-terrain vehicle 100 to operate in four-wheel drive mode. The front-wheel drive lock position locks the front wheels of the all-terrain vehicle 100. The mode switching switch 2031 includes a housing 2031d, a button plate 2031x, a switch shaft 2031t, and a gear lever unit 2031u. The housing 2031d includes a chamber 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 all located within the chamber 2031za. The second gear slot 2031f is located between the first gear slot 2031e and the third gear slot 2031j. The push plate 2031x is rotatably connected to the outer casing 2031d via the switch shaft 2031t. One end of the gear lever unit 2031u is connected to the push plate 2031x, and the other end of the gear lever unit 2031u can swing with the push plate 2031x and switch between the first gear slot 2031e, the second gear slot 2031f, and the third gear slot 2031j, thereby realizing the mutual switching between the two-wheel drive gear 2031a, the four-wheel drive gear 2031b, and the front-wheel drive lock gear 2031c.

[0088] Please refer to Figure 22The gear lever unit 2031u includes a switching lever 2031v, an elastic element 2031x, and a ball 2031y. One end of the switching lever 2031v is connected to the button plate 2031x and can swing within the outer casing 2031d under the action of the button plate 2031x. A fourth mounting hole 2031w is provided at the end of the switching lever 2031v away from the button plate 2031x. The elastic element 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 element 2031x. The other end can swing and fall into the first gear slot 2031e, the second gear slot 2031f, or the third gear slot 2031j.

[0089] like Figure 23 and Figure 24 As shown, the first gear slot 2031e, the second gear slot 2031f, and the third gear slot 2031j are all arc-shaped slots, and they are connected sequentially. 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 also 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 closest to the third gear slot 2031j is greater than the slope of the side of the second gear slot 2031f closest to the first gear slot 2031e, and the transition between the first gear slot 2031e and the second gear slot 2031f is gentler than the transition between the second gear slot 2031f and the third gear slot 2031j. Thus, when shifting gears, the damping of the shift lever 2031v when shifting from the second gear slot 2031f to the third gear slot 2031j is greater than the damping of the shift lever 2031v when shifting from the first gear slot 2031e to the second gear slot 2031f. This means that the force required to shift each gear is different, and the force required to shift from four-wheel drive to front-wheel drive lock-up gear 2031c is increased. This avoids the phenomenon of over-shifting when shifting from two-wheel drive gear 2031a to four-wheel drive gear 2031b, thus improving driving safety.

[0090] In one implementation, such as Figure 24As shown, along the Z-axis of chamber 2031za, the position of the second intersection point Q is relatively higher than the position of the first intersection point P. Thus, combined with the aforementioned angle, the travel distance between the four-wheel drive gear 2031b and the front-wheel drive lock-up gear 2031c can be extended, increasing the damping of the shift lever 2031v as it shifts from the second gear slot 2031f to the third gear slot 2031j, further preventing over-gearing during the shifting process.

[0091] Please refer to Figure 23 and Figure 24 The second gear slot 2031f includes a second arc-shaped segment 2031g, a first straight segment 2031h, and a second straight segment 2031i. One end of the first straight segment 2031h is connected to the first gear slot 2031e, and the other end is connected to the second arc-shaped segment 2031g. One end of the second straight segment 2031i is connected to the third gear slot 2031j, and the other end is connected to the second arc-shaped segment 2031g. The first gear slot 2031e includes at least a third straight segment 2031k, and the third gear slot 2031j includes 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°.

[0092] Furthermore, the first straight segment intersects plane A1 to form a third included angle β3, and the second straight segment intersects plane A1 to form 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°. This arrangement also ensures that the slope of the second straight segment 2031i relative to plane A1 is greater than the slope of the first straight segment 2031h relative to plane A1. Consequently, the force required for the switching lever 2031v to switch from the second gear slot 2031f to the third gear slot 2031j will increase.

[0093] In one embodiment, the third straight segment 2031k intersects plane A1 and forms a fifth included angle β5; the fourth straight segment 2031z intersects plane A1 and forms a sixth included angle β6, and the fifth included angle β5 and the sixth included angle β6 are substantially the same. This arrangement ensures that the operating force required to shift from two-wheel drive gear 2031a to four-wheel drive gear 2031b is substantially equal to the operating force required to shift from front-wheel drive lock gear 2031c to four-wheel drive gear 2031b, thus improving operational consistency.

[0094] like Figure 21 , Figure 25 and Figure 26As shown, the housing 2031d has an output contact 2031l, which protrudes from the outer surface of the housing 2031d. The output contact 2031l is connected to a circuit board on a corresponding switching device 203, such as the circuit board 1981n inside the mode switching switch 2031, the circuit board inside the air conditioner switch, or the circuit board inside the temperature control switch. The wiring harness 2042 has a connector 2031n that connects to the output contact 2031l, thereby enabling the switching device 203 to be electrically / signally connected to the electronic control unit 21. The outer surface of the housing 2031d has a connecting cover 2031m surrounding the output contact 2031l. The connecting cover 2031m can be integrated with the housing 2031d or be a separate component. The connecting cover 2031m or the connector 2031n is equipped with a sealing element 2031q. After the connector 2031n is mated with the output contact 2031l, the sealing element 2031q can seal the gap between the connector 2031n and the connecting cover 2031m, so that the output contact 2031l is in a relatively sealed state, preventing short circuit and burning of the output contact 2031l and the connector 2031n due to water or other factors. At the same time, during the mating process, the connecting cover 2031m also plays a guiding role, which is conducive to the connection between the connector 2031n and the output contact 2031l, making assembly more convenient.

[0095] In one embodiment, the connector 2031n has a second receiving groove 2031o and a second slot 2031p. The second receiving groove 2031o has a connection contact point corresponding to the output contact 2031l. The second slot 2031p surrounds the second receiving groove 2031o. A sealing member 2031q is disposed within the second slot 2031p. A connecting cover 2031m can be inserted into the second slot 2031p and is sealed to the sealing member 2031q. That is, sealing is achieved not only through the sealing member 2031q, but the connector 2031n also covers the connecting cover 2031m, increasing the sealing path and improving the sealing effect. The second receiving groove 2031o and the second slot 2031p are concentrically arranged. The sealing member 2031q is sleeved on the outer wall of the second slot 2031p. The sealing member 2031q is a rubber sealing ring or a silicone sealing ring. The outer circumferential side of the seal 2031q is provided with an annular sealing protrusion 2031r, which abuts against the inner wall of the connecting cover 2031m. Here, there are multiple sealing protrusions 2031r, and these protrusions are spaced apart axially along the second slot 2031p. In another embodiment, the seal 2031q can also be directly disposed on the inner wall of the connecting cover 2031m, with the connector 2031n inserted into the connecting cover 2031m and abutting against the seal 2031q.

[0096] like Figure 20As shown, the electrical assembly 19 includes a storage battery 1922 and an electrical connector unit 204. The storage battery 1922 is mounted on the center frame 1112 and is used to store electrical energy. The electrical connector unit 204 is connected to the storage battery 1922 via a wiring harness 2042 and is mounted on the frame 111 to power the modification parts of the all-terrain vehicle 100, thereby avoiding damage to the original wiring harness of the all-terrain vehicle 100 during the modification process.

[0097] like Figure 27 As shown, the electrical connector unit 204 includes a terminal block 2021, a wiring harness 2042, terminal blocks 2043, and a power lock 2044. Terminal blocks 2043 are connected to the battery via the wiring harness 2042. The power lock 2044 is connected between the terminal block 2021 and the battery 1922, and its opening and closing are linked to the opening and closing of the all-terrain vehicle 100. That is, when the all-terrain vehicle 100 is started or powered on, the power lock 2044 is open. When the all-terrain vehicle 100 is turned off, the power lock 2044 is closed. Terminal blocks 2043 include a first type of terminal block 2043a and a second type of terminal block 2043b. The first type of terminal block 2043a is electrically connected to the battery 1922 via the wiring harness 2042, and the second type of terminal block 2043b is electrically connected to the power lock 2044 via the wiring harness 2042, and then electrically connected to the battery 1922 via the power lock 2044. Therefore, the electrical connection between the second type terminal 2043b and the battery 1922 needs to be controlled by the power lock 2044. Thus, during the installation of aftermarket parts on the all-terrain vehicle 100, when the aftermarket parts require continuous power, the aftermarket parts can be connected to the corresponding first type terminal 2043a, which is not controlled by the power lock 2044. When the power supply to the aftermarket parts needs to be controlled by the on / off state of the all-terrain vehicle 100, the aftermarket parts can be connected to the corresponding second type terminal 2043b, which is controlled by the power lock 2044.

[0098] In some embodiments, such as Figures 27 to 29As shown, the first type of terminal 2043a includes a first terminal 2043c and a second terminal 2043d. The second type of terminal 2043b includes a third terminal 2043e. The first terminal 2043c is connected to the positive terminal of the battery 1922 via a wiring harness 2042, and the second terminal 2043d is connected to the negative terminal of the battery 1922, thus forming a continuous power supply circuit between the first terminal 2043c, the second terminal 2043d, and the positive and negative terminals of the battery 1922. The power lock 2044 is linked to the start 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 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 2043e via the wiring harness 2042. When the power lock 2044 is open, the third terminal 2043e is connected to the positive terminal of the battery 1922; when the power lock 2044 is closed, the third terminal 2043e is disconnected from the positive terminal of the battery 1922. Thus, the third terminal 2043e, power lock 2044, second terminal 2043d, and battery 1922 form a power supply circuit controlled by the power lock 2044. During the installation of modification parts on the all-terrain vehicle 100, when the modification parts require continuous power, they can be connected to the first terminal 2043c and the second terminal 2043d. When the power supply of the modification parts needs to be controlled by the on / off state of the all-terrain vehicle 100, the wiring harness of the modification parts can be connected to the second terminal 2043d and the third terminal 2043e.

[0099] In other implementations, such as Figure 30 As shown, the first type of terminal 2043a includes a first terminal 2043c and a second terminal 2043d, and the second type of terminal 2043b includes a third terminal 2043e and a fourth terminal 2043f. The first terminal 2043c is connected to the positive terminal of the battery 1922, and the second terminal 2043d is connected to the negative terminal of the battery 1922 to form a continuous power supply circuit. The third terminal 2043e is connected to the negative terminal of the battery 1922 via a wiring harness 2042, and the fourth terminal 2043f is connected to a power lock 2044 via the wiring harness 2042, and then connected to the positive terminal of the battery 1922 via the power lock 2044. This forms a power supply circuit controlled by the power lock 2044. Of course, the number of the first type of terminal block 2043a and the second type of terminal block 2043b can be three, four or other, respectively. The connection between the terminal block 2043 and the power lock 2044 and the battery 1922 can be a combination of the two embodiments described above, or one of the two embodiments described above or other forms. The specific choice can be set according to actual needs and is not limited here.

[0100] like Figure 27 and Figure 29 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.

[0101] 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.

[0102] like Figure 27 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.

[0103] 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. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0104] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
