[0059] 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.

[0060] 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 1 The front, rear, upper, lower, left, and right sides of the all-terrain vehicle 100 are defined.

[0061] like Figure 1 and Figure 3 As shown, the all-terrain vehicle 100 includes at least a frame assembly 11, a suspension assembly 22, and a wheel assembly 23. 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 suspension assembly 22 is mounted on the frame assembly 11 and supports the wheel assembly 23. It 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.

[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 set 17 and a rear wheel set 18. The front suspension assembly 15 is located near the front end of the all-terrain vehicle 100, mounted on the frame assembly 11, and connected to the front wheel set 17 to transmit 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. The rear suspension assembly 16 is located near the rear end of the all-terrain vehicle 100, mounted on the frame assembly 11, and connected to the rear wheel set 18 to transmit forces acting between the rear wheel set 18 and the frame assembly 11. Furthermore, the rear suspension assembly 16 can buffer the impact forces transmitted from uneven road surfaces to the frame assembly 11, etc., to reduce the resulting vibrations.

[0063] like 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 can vary, including two, three, or four. Of course, the specific number of the first type of beam 1112a and the specific number of the second type of beam 1112b can be selected according to the actual situation, and will not be elaborated here.

[0066] 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 located near the front end, and the second longitudinal beam 1112h is located near 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 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 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 all-terrain vehicle 100's passability 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. 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.

[0068] like Figure 6 As 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.

[0069] like 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.

[0070] 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.

[0071] 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.

[0072] like Figure 3 or Figure 4 As shown, the security unit 1116 includes a front bumper 1116a, side bumpers 1116b, and a rear bumper 1116c. The front bumper 1116a is located at the front end of the all-terrain vehicle 100 and is distributed circumferentially around the front frame 1111. The front bumper 1116a is connected to the first pillar 1111h. The rear bumper 1116c is located at the rear end of the all-terrain vehicle 100 and surrounds the rear frame 1113. Figure 10 The side bumper 1116b has first mounting holes 1116h on its end faces at both ends. The center frame 1112 has first connecting plates 1112c corresponding to the ends of the side bumper 1116b. The two ends of the side bumper 1116b extend from the outside to the inside of the all-terrain vehicle 100 through the vehicle body 112 and reach the first connecting plates 1112c, where they are mounted to achieve installation of the side bumper 1116b. Here, the side bumper 1116b is fixed to the first connecting plates 1112c by screws / bolts. The first connecting plates 1112c are sheet metal parts formed by stamping to improve the overall structural strength of the first connecting plates 1112c.

[0073] like Figure 2 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 exterior trim 1123 is located at the front end, rear end, 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.

[0074] like Figure 2 and Figure 11As shown, the 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 located near the front end of the all-terrain vehicle 100, separating the components at the front of the all-terrain vehicle 100 from the cabin 1121, and also serves to block stones, mud, sand, and water. The instrument panel 1122b is mounted on the end of the front fender 1122a away from the ground, and is used to support 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, serving as a support plate to support various components such as the seat 1122f, and to provide a footrest for the driver or passengers. The rear fender 1122d is located near the rear end of the all-terrain vehicle 100, and separates the components at the rear of the all-terrain vehicle 100 from the cabin 1121. The rear panel 1122d and the front panel 1122a are spaced apart, and the foot pedal 1122c is located between the rear panel 1122d and the front panel 1122a. Thus, these three elements together form the aforementioned cabin 1121. A seat 1122f is detachably mounted on the foot pedal 1122c for use by a passenger or driver. In one embodiment, there are two seats 1122f, arranged side-by-side. One seat 1122f is designated for passenger use, and the other seat 1122f is designated for the driver's seat.

[0075] like Figure 11 and Figure 12As shown, various electrical components are typically installed at the instrument panel 1122b. These components are consumables and therefore require periodic inspection and maintenance. Currently, inspecting these components requires removing the entire front panel 1122a and / or instrument panel 1122b to visualize and repair them. However, this complete removal is cumbersome, inconvenient, and hinders subsequent installation. Therefore, in this application, an instrument access port 1122bh is provided on the instrument panel 1122b and / or front panel 1122a. Electrical components or their connections to other components are located at this port, allowing for observation and repair. The second cover plate 1122bi can cover the instrument access port 1122bh. The second cover plate 1122bi is detachably connected to the instrument panel 1122b or the front baffle 1122a. This detachable connection can be achieved through threaded connections, snap-fit ​​connections, or other methods. When maintenance of the electrical components is required, the second cover plate 1122bi can be removed, allowing for easy and simple maintenance through the instrument panel access port 1122bh. Furthermore, for enhanced visibility, the second cover plate 1122bi can also be equipped with a transparent window, allowing for easy observation of the status of the electrical components located at the instrument panel access port 1122bh.

[0076] As shown in the figure Figure 4 and Figure 14 As shown, the foot pedal 1122c is mounted on the center frame 1112, and a bumper access port 1122cc is provided on the foot pedal 1122c. The bumper access port 1122cc is positioned to align with the connection point between the side bumper 1116b and the first connecting plate 1112c. This means that the side bumper 1116b can be installed and removed through the bumper access port 1122cc; or, in other words, the connection between the side bumper 1116b and the first connecting plate 1112c is arranged around the bumper access port 1122cc. This not only conceals the connection between the side bumper 1116b and the frame 111, but also eliminates the need to disassemble the entire foot pedal 1122c and other components for maintenance and installation of the side bumper 1116b. This results in simpler and more convenient maintenance, a more aesthetically pleasing concealed installation, and a more concealed design.

[0077] like Figure 15As shown, the bumper access port 1122cc is covered with a third cover plate 1122cd, which is detachably connected to the foot pedal 1122c. Here, the third cover plate 1122cd and the foot pedal 1122c can be connected via threaded parts, clips, etc. This facilitates opening / closing the bumper access port 1122cc, improving the convenience of installation and maintenance of the side bumper 1116b. In one embodiment, the foot pedal 1122c includes a side surface and a bottom surface, and the bumper access port 1122cc extends from the bottom surface to the side surface. This increases the usable area of ​​the bumper access port 1122cc, providing maintenance personnel with a sufficiently large operating space.

[0078] like Figure 2 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 and an air intake grille 1123ac. The front panel 1123aa covers the upper surface of the front frame 1111 to shield the components mounted on the front frame 1111. 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 inspection and maintenance of components at the front frame 1111. The central trim piece 1123h includes a central side plate 1123ha, which covers the side of the central frame 1112. The two ends of the side bumper 1116b are respectively inserted through the central side plate 1123ha, thereby connecting with the corresponding first connecting plate 1112c.

[0079] like Figure 2 and Figure 16 As shown, the front panel 1123aa has a front access port 1123ae, which is used for inspecting and repairing components mounted on the front frame 1111, such as heat exchangers. A front cover plate 1123ad is mounted on the front panel 1123aa, covering the front access port 1123ae so that it can be sealed when maintenance is not required. The front cover plate 1123ad and the front panel 1123aa can be detachably connected via a snap-fit ​​connection or a threaded connection. This facilitates opening and closing of the front access port 1123ae. It should be noted that the specific connection method used between the front cover plate 1123ad and the front panel 1123aa can be selected based on actual needs and applications, as long as it allows for easy removal and installation of the front cover plate 1123ad for maintenance.

[0080] Please combine Figure 2 The air intake grille 1123ac is installed on the front end of the front frame 1111 for end face protection of the all-terrain vehicle 100. The air intake grille 1123ac can be detachably connected to the front panel 1123aa and / or the front frame 1111. Along the left-right direction (width direction) of the all-terrain vehicle 100, the ratio of the width of the air intake 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. This gives the air intake grille 1123ac a large air intake area, facilitating sufficient heat exchange by the heat exchanger. Moreover, the large area of ​​the air intake grille 1123ac allows for the inspection and maintenance of almost all parts and components on the front end face of the all-terrain vehicle 100 after the air intake grille 1123ac is removed, making maintenance more convenient.

[0081] like Figure 1 , Figure 17 as well as Figure 23 As shown, the control assembly 13 includes a gear shift mechanism 131, which is mounted on the frame 111. One end of the gear shift mechanism 131 is connected to the transmission 122 in the power assembly 12, and the other end is located inside the cabin 1121 for the driver to operate and shift gears. In addition to the gear shift mechanism 131, the control assembly 13 also includes a braking mechanism, a steering mechanism, and other structures. The braking mechanism is used for braking the all-terrain vehicle 100. The steering mechanism is operated by the driver to control the driving direction of the all-terrain vehicle 100. These mechanisms cooperate with each other to achieve the basic driving operation functions of the all-terrain vehicle 100.

[0082] like Figure 17 As shown, the transmission control mechanism 131 includes a carrier 1311, a transmission component 1314, and a shift lever 1317. The carrier 1311 is mounted on the frame 111. One end of the shift lever 1317 is rotatably mounted within the carrier 1311, and the other end extends into the cabin 1121 to serve as part of the driver's gear shifting operation. One end of the transmission component 1314 is connected to the shift lever 1317, and the other end extends toward the rear end of the all-terrain vehicle 100 and is connected to the transmission 122 to transmit the shift command from the shift lever 1317 to the transmission 122. When a gear shift is required, the driver operates the shift lever 1317 and transmits the shift signal to the transmission 122 via the transmission component 1314, causing the transmission 122 to change its speed or direction, thereby controlling the power output of the engine 121.

[0083] like Figure 18As shown, the support member 1311 includes a fifth connecting plate 1312 and a protective cover 1313, and the foot pedal 1122c includes a second mounting hole 1122ce. The fifth connecting plate 1312 can be installed on the frame 111 by welding or screw connection. At least a portion of the fifth connecting plate 1312 is located at the second mounting hole 1122ce to connect with the gear shift lever 1317. The protective cover 1313 covers the second mounting hole 1122ce and connects with the foot pedal 1122c, thereby making the foot pedal 1122c form a whole, with a more compact and aesthetically pleasing structure. It can be understood that by directly installing the fifth connecting plate 1312 on the frame 111, and the gear shift lever 1317 being directly connected to the fifth connecting plate 1312, the existing gear shift mounting base and other components are omitted, which not only simplifies the structure but also reduces the cost by at least 30%. Meanwhile, since the fifth connecting plate 1312 and the gear shift lever 1317 are independent components, the fifth connecting plate 1312 can be pre-fixed to the frame 111 during installation. Therefore, when installing the gear shift lever 1317, it can be directly installed onto the fifth connecting plate 1312, eliminating the need for additional sheet metal parts or supports. This makes the connection convenient, the structure simple, and the cost low.

[0084] like Figure 17 As shown, the transmission component 1314 includes a fourth cable 1315 and an adjuster 1316. One end of the fourth cable 1315 is connected to the transmission 122, and the other end is connected to the shift lever 1317. The adjuster 1316 is mounted on the fourth cable 1315 and is used to adjust the tension of the fourth cable 1315 to compensate for installation errors of the shift lever 1317 and loosening of the fourth cable 1315 due to wear. Operating the shift lever 1317 causes the rocker arm of the transmission 122 to move via the fourth cable 1315, thereby changing the transmission ratio of the transmission 122 and thus changing the power output of the engine 121, i.e., shifting gears.

[0085] like Figure 20 As shown, the foot pedal 1122c also has a shift access port 1122cf, the position of which corresponds to the position of the regulator 1316; or rather, the regulator 1316 is positioned around the shift access port 1122cf, allowing maintenance personnel to inspect and adjust the regulator 1316 through the shift access port 1122cf. This enables quick inspection and adjustment of the regulator 1316, avoids disassembling numerous cover parts, and facilitates maintenance. Of course, the shift access port 1122cf is not limited to the inspection of the regulator 1316; it can also be used to inspect all components located in this area.

[0086] like Figure 20As shown, the foot pedal 1122c has a raised portion 1122cg protruding into the cabin 1121 on the ground-facing side, and the raised portion 1122cg has the aforementioned second mounting hole 1122ce. The protective cover 1313 is connected to the raised portion 1122cg and covers the second mounting hole 1122ce. The shift access port 1122cf is located on the side of the raised portion 1122cg and the bottom surface of the foot pedal 1122c, thus forming an "L"-shaped shift access port 1122cf, maximizing the area of ​​the shift access port 1122cf, thereby facilitating the maintenance of the regulator 1316. When maintenance is not required, the shift access port 1122cf is sealed by the fourth cover plate 1122cj, so that the foot pedal 1122c is a single unit during daily use.

[0087] like Figures 20 to 22 As shown, the fourth cover plate 1122cj and the foot pedal 1122c are connected by a detachable structure such as a snap-fit ​​structure or a threaded structure, thereby facilitating the assembly and disassembly of the fourth cover plate 1122cj. In one embodiment, the foot pedal 1122c is provided with an insertion interface 1122ch and a locking interface 1122ci at the shift access port 1122cf. The insertion interface 1122ch and the locking interface 1122ci are arranged opposite to each other, that is, the insertion interface 1122ch and the locking interface 1122ci are located on opposite sides of the shift access port 1122cf. The corresponding fourth cover plate 1122cj is provided with a second insertion part 1122ck and a locking part 1122cl. The second insertion part 1122ck is inserted into the insertion interface 1122ch, and the locking part 1122cl is locked into the locking interface 1122ci, so as to realize the detachable connection between the foot pedal 1122cj and the fourth cover plate 1122cj. Of course, the positions of the plug interface 1122ch and the second plug part 1122ck can be interchanged, and the positions of the card interface 1122ci and the card part 1122cl can also be interchanged.

[0088] like Figure 21 As shown, to achieve the integrity of the fourth cover plate 1122cj and the foot pedal 1122c, a recess 1122cm is provided on the foot pedal 1122c, and the shift access port 1122cf is located at the bottom of the recess 1122cm. After the fourth cover plate 1122cj covers the shift access port 1122cf, the fourth cover plate 1122cj is located within the recess 1122cm, and the surface of the fourth cover plate 1122cj is basically flush with the surface of the foot pedal 1122c, thereby making the fourth cover plate 1122cj and the foot pedal 1122c form an integral structure, improving the overall integrity and aesthetics.

[0089] Please combine Figure 22A guide structure 1122cn is provided between the fourth cover plate 1122cj and the foot pedal 1122c. The guide structure 1122cn is used to guide the installation of the fourth cover plate 1122cj so that the snap-fit ​​part 1122cl can quickly snap into the snap-fit ​​interface 1122ci. In one embodiment, the guide structure 1122cn includes a guide part 1122co, and the foot pedal 1122c is provided with a guide groove 1122cp. When the fourth cover plate 1122cj covers the foot pedal 1122c, the guide part 1122co is inserted into the guide groove 1122cp, thereby guiding the snap-fit ​​part 1122cl into the snap-fit ​​interface 1122ci. Of course, the positions of the guide part 1122co and the guide groove 1122cp can be interchanged. At the same time, the guide structure 1122cn is not limited to the described cooperation of the guide part 1122co and the guide groove 1122cp; it can also be a sloped guide, etc.

[0090] In one embodiment, there are at least two guide grooves 1122cp, and the two guide grooves 1122cp are positioned relative to each other, with the guide grooves 1122cp located between the insertion interface 1122ch and the card interface 1122ci. Meanwhile, the guide grooves 1122cp, the insertion interface 1122ch, and the card interface 1122ci are all located at the bottom of the sink and surround the circumference of the gear shift inspection port 1122cf.

[0091] like Figure 23 As shown, the all-terrain vehicle 100 also includes a power assembly 12 and an air hose assembly 14. The power assembly 12 is mounted on the frame assembly 11 and serves as a power source to provide power for the movement of the all-terrain vehicle 100. The air hose assembly 14 is connected to the power assembly 12 and is used to supply 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 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 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 gas for the internal combustion of the engine 121 and to promptly exhaust combustion gases. 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, to the transmission 122 for cooling.

[0092] like Figure 23 and Figure 24As shown, the first air intake unit 141 includes a first intake pipe 1411, a first exhaust pipe 1412, and an air filter 146. One end of the first intake pipe 1411 is connected to the engine 121, and the other end extends upward for gas intake. One end of the first exhaust pipe 1412 is connected to the engine 121, and the other end extends along the rear of the all-terrain vehicle 100 to facilitate the exhaust of exhaust gases after fuel combustion. The air filter 146 is mounted on the first intake pipe 1411 and fixed to the frame 111 or the body 112. The air filter 146 is used to filter the air entering the first intake pipe 1411 so that the gas entering the engine 121 meets the usage requirements. Furthermore, as... Figure 25 As shown, the air filter 146 is equipped with a wire bracket 1461, which can be used to fix brake lines, electrical wiring harnesses, carbon canister lines, etc. This reduces the need for openings in the frame 111 and the addition of other supports, ensuring structural strength while reducing overall vehicle cost and weight. It should be noted that the air filter 146 is a routine maintenance item, requiring regular cleaning or replacement of its filter element. The position of the air filter 146 affects the ease of filter element replacement and whether dust or sediment will be introduced into the power assembly 12 during replacement, affecting its lifespan. This application addresses these issues by modifying the layout of the all-terrain vehicle 100 and adjusting the position of the air filter 146 to make replacement quick and convenient while preventing filter contamination during replacement.

[0093] like Figure 2 , Figure 26 As shown, a through-hole filter access port 1121b is provided on the cavity wall of the cabin 1121 near the rear end of the all-terrain vehicle 100, and the air filter 146 is located at the filter access port 1121b. This means that the air filter 146 can be repaired and maintained through the filter access port 1121b. Thus, the cabin 1121, primarily serving as the space for the driver and passengers, is the cleanest area in the entire vehicle compared to the overall environment. Specifically, by arranging the engine 121 and the first air intake pipe 1411, the air filter 146 is positioned at the filter access port 1121b, reducing the chance of contamination during filter replacement. Simultaneously, it avoids the need to remove the corresponding body panels 112, reducing the possibility of dust or sand being brought into the air filter 146 during maintenance.

[0094] like Figure 26As shown, the filter access port 1121b is located on the rear panel 1122d. The seat 1122f is detachably connected to the frame 111 or body 112 and can be quickly removed. The filter access port 1121b is positioned directly opposite the seat 1122f, and its projection is located on the seat 1122f. Therefore, when the air filter 146 does not require maintenance or the filter element does not require upkeep, the filter access port 1121b is blocked by the seat 1122f to prevent some dust from entering the filter access port 1121b.

[0095] Combination Figure 29 Along the vertical direction of the all-terrain vehicle 100, the filter access port 1121b is located above the rear frame 1113; and along the longitudinal direction of the all-terrain vehicle 100, the filter access port 1121b is located at the rear end of the seat 1122f and the front end of the cargo box 1123ba. That is, along the longitudinal direction of the all-terrain vehicle 100, the filter access port 1121b is located between the seat 1122f and the cargo box 1123ba. This allows for the highest possible air filter chamber height, thereby increasing the wading depth of the all-terrain vehicle 100.

[0096] like Figures 26 to 32 As shown, a covering unit 1127 is provided at the filter element access port 1121b. The covering unit 1127 covers and seals the filter element access port 1121b, thereby preventing dust and other contaminants from entering the air filter 146 when maintenance or repair of the air filter 146 is not required. It is understandable that, since the filter element access port 1121b is located inside the housing 1121, and considering the environment of the housing 1121, the sealing performance of the covering unit 1127 can be appropriately reduced, thus decreasing the production cost of the covering unit 1127. Furthermore, even if the seal of the covering unit 1127 fails, the dust prevention function of the air filter 146 will not fail due to its location.

[0097] Please refer to Figure 29The covering unit 1127 includes a first cover 1127a and a second cover 1127e. The air filter 146 includes a housing 1462, which is mounted on the first intake pipe 1411. The filter element is installed inside the housing 1462 and filters the gas entering the first intake pipe 1411. The housing 1462 has an opening (not shown) facing the filter element access port 1121b. The filter element is installed inside the housing 1462 through the filter element access port 1121b and the opening. The first cover 1127a covers the opening and is detachably connected to the housing 1462. The second cover 1127e covers the filter element access port 1121b and is detachably connected to the vehicle body 112 inside the compartment 1121. The second cover 1127e covers the first cover 1127a. When the filter element needs to be replaced, the movable seat 1122f is used to make room for operation by removing the first cover 1127a and the second cover 1127e. Then, the second cover 1127e and the first cover 1127a are removed, so that the filter element can be exposed to the maintenance field of vision, and then the corresponding maintenance and repair can be carried out.

[0098] like Figure 30 As shown, the first cover 1127a and the outer shell 1462 are connected by a quick-release structure. This eliminates the need for additional power tools to disassemble and assemble the first cover 1127a, making the disassembly and assembly of the first cover 1127a, as well as the repair and maintenance of the air filter 146, much more convenient and simpler. For example, along the vertical direction, one end of the first cover 1127a has a first latch 1127b, and the other end has a second latch 1127c, with the second latch 1127c positioned above the first latch 1127b. Correspondingly, the outer shell 1462 has a first slot 1463 and a second slot 1464. The first latch 1127b can be engaged in the first slot 1463, and the second latch 1127c can be engaged in the second slot 1464, thus achieving a quick-release connection between the first cover 1127a and the outer shell 1462. When it is necessary to disassemble the first cover 1127a, the first latch 1127b and the second latch 1127c simply need to disengage from the first slot 1463 and the second slot 1464, respectively. It is understood that the positions of the latches and slots can be interchanged. That is, the latches can be positioned on the outer casing 1462, and the latches can be positioned on the first cover 1127a. Of course, the quick-release structure is not limited to the example above; it can also be a threaded structure, etc.

[0099] like Figure 31 and Figure 32As shown, the covering unit 1127 also includes a second limiting part 1127h and a second spring clip 1127i. The second limiting part 1127h is disposed near the first buckle 1127b, and one side of the first cover 1127a can abut against the second limiting part 1127h to form a limit in the front-rear direction of the all-terrain vehicle 100, preventing the first buckle 1127b from disengaging from the first slot 1463. The second spring clip 1127i is disposed near the other end of the first cover 1127a, and the outer shell 1462 is provided with a spring clip shaft 1455. One end of the second spring clip 1127i is connected to the spring clip shaft 1455. The side of the first cover 1127a away from the outer shell 1462 has a spring clip groove 1127d. Under external force, the second spring clip 1127i deforms, causing a portion of it to engage within the spring clip groove 1127d, and tightly pressing the first cover 1127a against the outer shell 1462, thus locking the first cover 1127a. This prevents vibrations of the all-terrain vehicle 100 from causing the first cover 1127a to detach from the outer shell 1462, improving the reliability and stability of the connection. Furthermore, no additional power tools are required during repair or maintenance, making repair and maintenance more convenient.

[0100] like Figure 26 and Figure 32 As shown, the second cover 1127e is also connected to the vehicle body 112 via a quick-release structure, eliminating the need for additional power tools and making the disassembly and assembly of the second cover 1127e, as well as the repair and maintenance of the air filter 146, more convenient and simple. One end of the second cover 1127e has a positioning part 1127f, and the other end has a deformation part 1127g. The positioning part 1127f is located near the first latch 1127b. The deformation part 1127g is located near the second spring clip 1127i. The filter element inspection port 1121b has a first mating part 1121f on its wall that mates with the positioning part 1127f. The first mating part 1121f mates with the positioning part 1127f. The deformation part 1127g deforms under external force and abuts against the wall of the filter element inspection port 1121b. Thus, under the deformation force of the deformation part 1127g, the second cover 1127e seals the filter element inspection port 1121b. Alternatively, a corresponding slot can be provided in the filter element inspection port 1121b to allow the deformation part 1127g to engage within it. When the second cover 1127e needs to be removed, simply press the deformation part 1127g to create a gap between it and the interior of the filter element inspection port 1121b. The second cover 1127e can then be pulled out of the filter element inspection port 1121b entirely through the deformation part 1127g for maintenance. Of course, the quick-release structure is not limited to the above example; it can also be a threaded structure, etc.

[0101] The maintenance and repair steps for the air filter 146 are described below: First, move the seat 1122f to provide sufficient operating space between the seat 1122f and the rear panel 1122d; Second, the operator presses down firmly on the deformable part 1127g to disengage the second cover 1127e from the filter element inspection port 1121b, thereby removing the second cover 1127e; Third, the operator lifts the second spring clip 1127i to disengage it from the spring clip groove 1127d, releasing the locking force of the first cover 1127a; Fourth, under the action of external force, the buckle disengages from the corresponding groove, thus removing the first cover 1127a; Fifth, remove the filter element from the housing 1462 and install a new or cleaned filter element in the housing 1462, then install the first cover 1127a and the second cover 1127e in sequence, thus completing the maintenance and repair of the air filter 146. Understandably, as can be seen from the above steps, the maintenance of the air filter 146 does not require the disassembly of any external accessories of the vehicle body 112, reducing the probability of dust or mud being brought into the power assembly 12 during the replacement process, as well as the possibility of the filter element being contaminated; at the same time, the above structures all adopt quick-release structures, which do not require the use of additional electrician tools, making replacement quick and convenient.

[0102] like Figure 33 As shown, the all-terrain vehicle 100 also includes an electrical assembly 19 and an electronic control unit (ECU) 21. The electrical assembly 19 is mounted on the frame assembly 11 and is used to implement the basic electrical functions of the all-terrain vehicle 100. The electronic control unit 21, also known as the "vehicle computer," is mounted on the frame assembly 11 and is used to monitor various input data (such as braking, gear shifting, etc.) and various vehicle operating states (acceleration, slippage, fuel consumption, etc.). It calculates the information transmitted by various sensors according to a pre-designed program, processes it, and sends the parameters to the relevant actuators to execute various predetermined control functions. Here, the actuators can be the control assembly 13, the electrical assembly 19, etc.

[0103] like Figure 2 and Figure 26 As shown, along the longitudinal direction of the all-terrain vehicle, an ECU access port 1121c is provided behind the seat 1122f. The ECU access port 1121c is located on the cavity wall of the cabin 1121, and the electronic control unit 21 can be inspected and maintained through the ECU access port 1121c. Thus, when the electronic control component 21 needs maintenance, there is no need to disassemble other large components, greatly improving maintenance convenience. In other words, the ECU access port 1121c is provided through the cavity wall of the cabin 1121 near the rear end of the all-terrain vehicle 100, and the electronic control component 21 is located correspondingly at the ECU access port 1121c.

[0104] In one embodiment, the ECU access port 1121c is located on the rear panel 1122d and between the rear panel 1122d and the seat 1122f. Along the longitudinal direction of the all-terrain vehicle 100, the orthogonal projection of the ECU access port 1121c is located on the seat 1122f. It is understood that the seat 1122f in this application is detachably connected to the frame 111 or the body 112 and can be quickly removed. Thus, when the ECU access port 1121c does not need to be opened, it is concealed by the seat 1122f, thereby maintaining the integrity and cleanliness of the compartment 1121. Simultaneously, to prevent impurities, water, etc., from entering the compartment 1121 from the ECU access port 1121c, an ECU cover 1121d is provided at the ECU access port 1121c. The ECU cover 1121d is connected to the rear panel 1122d via a quick-release structure to facilitate opening / closing the ECU access port 1121c. The ECU cover 1121d and the rear baffle 1122d can be quickly connected using snap-fit ​​components, threaded components, or other means. In this embodiment, the ECU cover 1121d and the rear baffle 1122d are connected by a snap-fit ​​mechanism. The specific structure of this snap-fit ​​mechanism can be referenced from the snap-fit ​​methods used for access panel covers and corresponding components in other locations of this application, and will not be elaborated upon here.

[0105] In one embodiment, the ratio of the area of ​​the ECU access port 1121c to the area of ​​the rear baffle 1122d is greater than or equal to 0.2 and less than or equal to 0.4, meaning that the area of ​​the ECU access port 1121c occupies 20% to 40% of the area of ​​the rear baffle 1122d. This ensures that the ECU access port 1121c has sufficient operating space for operator access. Simultaneously, a recess is formed on the rear baffle 1122d, with the ECU access port 1121c located at the bottom of the recess. When the ECU cover 1121d covers the ECU access port 1121c, the ECU cover 1121d is contained within the recess, thus forming a single unit with the rear baffle 1122d.

[0106] Furthermore, the ECU access port 1121c and the filter access port 1121b are arranged side by side and on the same horizontal plane. There are two seats 1122f, also arranged side by side. Along the longitudinal direction of the all-terrain vehicle 100, the ECU access port 1121c is located behind one of the seats, and the filter access port 1121b is located behind the other seat 1122f.

[0107] like Figure 33As shown, the electrical assembly 19 includes a battery 1922, a diagnostic interface 193, a fuse box 194, and instrument cluster 200. The battery 1922 is mounted on the frame 111 and stores electricity to power other electrical components. The diagnostic interface 193 connects to an external vehicle diagnostic tool to inspect the components and systems of the all-terrain vehicle 100, ensuring that the vehicle's emissions do not exceed OBD (On-Board Diagnostics) regulations during its service life. The fuse box 194 integrates vehicle fuses to protect the various electrical components. The instrument cluster 200 includes various electrical gauges, such as an ammeter, charging indicator or voltmeter, oil pressure gauge, temperature gauge, fuel gauge, speedometer, odometer, and tachometer. The instrument cluster 200 primarily displays the operating status of relevant devices while the all-terrain vehicle 100 is in motion. The instrument cluster 200 is also connected to the electronic control unit 21 via wiring harnesses. Furthermore, the connection between the instrument device 200 and the electronic control unit 21 can be located inside the instrument inspection port 1122bh, thereby enabling maintenance of this connection through the instrument inspection port 1122bh and improving the convenience of maintenance. Of course, in the all-terrain vehicle 100, the electrical components 19 also include components such as a starting relay, a rectifier voltage regulator, a lighting unit, and a sound-generating device.

[0108] like Figure 28 As shown, the diagnostic interface 193 and fuse box 194 are both mounted on the rear frame 1113 and positioned close to the electronic control unit 21, located at the ECU access port 1121c. This means that the diagnostic interface 193 and fuse box 194 can be operated through the ECU access port 1121c. This allows for simultaneous maintenance of the ECU, diagnostic interface 193, and fuse box 194, effectively improving maintenance efficiency.

[0109] like Figure 33As shown, the electrical component 19 also includes a switching device 203 and an electrical connector unit 204. The switching device 203 is connected to the electronic control unit 21 or other electrical components to control the opening and closing of the corresponding components. The switching device 203 includes a mode switching switch 2031, an air conditioning switch (not shown), and a temperature control switch (not shown). The mode switching switch 2031, air conditioning switch, and temperature control 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 control switch are all electrically / signally connected to the ECU via wiring harnesses, 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. Furthermore, the wiring harness connections between the switching device 203 and various components are arranged around the instrument panel access port 1122bh, allowing for maintenance of the switching device 203 through the instrument panel access port. The electrical connector unit 204 is connected to the battery 1922 via 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.

[0110] As can be understood from the above description of electrical component 19, at least a portion of the connections between electrical component 19 and electronic control unit 21 are distributed around the instrument access port 1122bh. This allows for maintenance of these connections via the instrument access port 1122bh. Of course, the above only shows that these connections can be distributed around the instrument access port 1122bh. In other embodiments, these connections may also be distributed around, for example, the filter access port 1121b, the ECU access port 1121c, etc.

[0111] In one embodiment, such as Figures 34 to 37As 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.

[0112] Please refer to Figure 35 The 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.

[0113] like Figures 35 to 37As 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.

[0114] In one implementation, such as Figure 37 As 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.

[0115] Please refer to Figure 35 and Figure 37The 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°.

[0116] 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.

[0117] 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.

[0118] like Figure 38 and Figure 39As 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.

[0119] 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.

[0120] like Figure 40As 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.

[0121] In some embodiments, such as Figures 40 to 42As 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.

[0122] In other implementations, such as Figure 43 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.

[0123] like Figure 40 and Figure 42 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.

[0124] 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.

[0125] like Figure 40 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.

[0126] 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.

[0127] 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.
