[0037] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0038] As Figure 1 shown, the present application provides an all-terrain vehicle 100. As a general-purpose tool, the all-terrain vehicle 100 can travel normally in many terrains such as beaches, hillsides, and deserts. To clearly illustrate the structure of the all-terrain vehicle 100, the present application defines the front end, rear end, upper side, lower side, left side, and right side of the all-terrain vehicle 100 in Figure 1 . The all-terrain vehicle 100 at least includes a frame assembly 11, 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 a skeleton for carrying and connecting various components on the all-terrain vehicle 100 and withstanding various loads from inside and outside the vehicle. The front suspension assembly 15 is disposed near the front end of the all-terrain vehicle 100. It is mounted on the frame assembly 11 and connected to the front wheel set 17 to transmit the force acting between the front wheel set 17 and the frame assembly 11. Moreover, the front suspension assembly 15 can buffer the impact force transmitted from the uneven road surface to the frame assembly 11, etc., to reduce the resulting vibration. The rear suspension assembly 16 is disposed near the rear end of the all-terrain vehicle 100. It is mounted on the frame assembly 11 and connected to the rear wheel set 18 to transmit the force acting between the rear wheel set 18 and the frame assembly 11. And, the rear suspension assembly 16 and the front suspension assembly 15 can buffer the impact force transmitted from the uneven road surface to the frame assembly 11, etc., to reduce the resulting vibration.

[0039] The frame assembly 11 includes a frame 111 and a body 112. The frame 111 adopts a frame structure and serves as a base to carry various loads inside and outside the vehicle. The front suspension assembly 15 and the rear suspension assembly 16 are respectively mounted on the front end and the rear end 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 correspondingly according to needs, which will not be elaborated here. The body 112 is mounted on the frame 111 and wraps at least part of the frame 111, thereby protecting the components on the frame 111. At the same time, the body 112 is also a driving place for the driver and a place for accommodating passengers and goods.

[0040] As Figures 2 to 3As shown in the figure, the vehicle 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 end of the all-terrain vehicle 100 to carry or arrange the corresponding components located at the front end, such as the front suspension assembly 15, the front headlight, the water tank, etc. The rear frame 1113 is located at the rear end of the all-terrain vehicle 100 to carry or arrange the corresponding components such as the rear suspension assembly 16 located at the rear end. The middle frame 1112 serves as a connecting and load-bearing component, and the front frame 1111 and the rear frame 1113 are respectively connected to the middle frame 1112. Moreover, the front frame 1111, the middle frame 1112, and the rear frame 1113 enclose a receiving space 111a. The vehicle body 112 covers the vehicle frame 111, and a cabin 1121 is provided on the vehicle body 112. The cabin 1121 is used as a driver's cab and / or a passenger cabin for the driver or passengers. The cabin 1121 can be partially embedded in the receiving space 111a and installed on the vehicle frame 111, so that when the height of the all-terrain vehicle 100 meets the standard, the cabin 1121 can obtain a larger usable space.

[0041] As Figures 4 to 6 shown, the middle frame 1112 serves as a structure for the all-terrain vehicle 100 to bear the core load. The middle frame 1112 includes a first type of beam 1112a and a second type of beam 1112b. The first type of beam 1112a and the second type of beam 1112b are connected to each other to basically form a load-bearing structure. In an embodiment, the number of the first type of beam 1112a is multiple, and the multiple first type of beam 1112a are arranged at intervals and are basically located in the same plane. Here, the plane where the first type of beam 1112a is located is set as plane S. The number of the second type of beam 1112b is also multiple, and the multiple second type of beam 1112b are arranged at intervals between the multiple first type of beam 1112a. It can be understood that the number of the first type of beam 1112a can be set to two, three, or four, etc. Similarly, the number of the second type of beam 1112b can be set to two, three, or four, etc. 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.

[0042] In this embodiment, the first type of beam 1112a includes a first cross beam 1112c and a second cross beam 1112d. The second type of beam 1112b includes a first longitudinal beam 1112e and a second longitudinal beam 1112h. Along the front-to-rear direction of the all-terrain vehicle 100, the first longitudinal beam 1112e is disposed near the front end, and the second longitudinal beam 1112h is disposed near the rear end. Wherein, the first longitudinal beam 1112e includes a first rod 1112f and a second rod 1112g. One end of the first rod 1112f is connected to the first cross beam 1112c, and the other end of the first rod 1112f extends towards the second cross beam 1112d, and the angle between the first rod 1112f and the plane S is A1, and A1 is set to be greater than or equal to 5° and less than or equal to 15°. One end of the second rod 1112g is connected to the second cross beam 1112d, and the other end of the second rod 1112g extends towards the first cross beam 1112c and is connected to the first rod 1112f. The angle between the second rod 1112g and the plane S is A2, and A2 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 middle frame 1112 can be made to bulge upward (away from the driving surface). That is, the bottom of the middle frame 1112 bulges upward. Thus, the ground clearance of the all-terrain vehicle 100 at the middle frame 1112 is increased, effectively improving the passability of the all-terrain vehicle 100 during driving.

[0043] In an embodiment, the angle A1 between the first rod 1112f and the plane S is greater than the angle between the second rod and the plane S. Thus, when the all-terrain vehicle 100 passes through a continuously uneven road surface, a better passability can be maintained. Further, the first type of beam 1112a and the second type of beam 1112b are respectively made by cutting steel pipes. Thus, both the material selection and processing are convenient. The first rod 1112f is welded to the first cross beam 1112c, and the second rod 1112g is welded to the second cross beam 1112d. The first rod 1112f and the second rod 1112g are welded to each other. The first rods 1112f in the second type of beam 1112b are arranged parallel to each other, and the second rods 1112g in the second type of beam 1112b are arranged parallel to each other. That is, the second longitudinal beam 1112h includes a third rod 1112i and a fourth rod 1112j. The third rod 1112i is parallel to the first rod 1112f, and one end of the third rod 1112i is connected to the first cross beam 1112c, and the other end of the third rod 1112i extends towards the second cross beam 1112d. The fourth rod 1112j is parallel to the second rod 1112g, and one end of the fourth rod 1112j is connected to the second cross beam 1112d, and the other end of the fourth rod 1112j extends towards the first cross beam 1112c and is connected to the third rod 1112i.

[0044] Such as Figure 5As shown, the middle frame 1112 further includes longitudinal reinforcing tubes 1112k and transverse reinforcing tubes 1112l. The number of longitudinal reinforcing tubes 1112k is at least two. In this embodiment, taking two as an example, the position and installation of the longitudinal reinforcing tubes 1112k will be specifically described. The two longitudinal reinforcing tubes 1112k are arranged at intervals, and the second type of beam 1112b is located between the two longitudinal reinforcing tubes 1112k. One end of each longitudinal reinforcing tube 1112k is fixed to the first cross beam 1112c, and the other end is fixed to the second cross beam 1112d. The transverse reinforcing tube 1112l is arranged between the longitudinal beam 1112b and the corresponding longitudinal reinforcing tube 1112k, and one end of the transverse reinforcing tube 1112l is connected to the longitudinal beam, and the other end of the transverse reinforcing tube 1112l is connected to the longitudinal reinforcing tube 1112k. Thus, the longitudinal reinforcing tubes 1112k, the transverse reinforcing tubes 1112l, the cross beam 1112a and the longitudinal beam 1112b jointly form a structure similar to a net, effectively improving the structural strength and load-bearing capacity of the entire middle frame 1112.

[0045] As Figure 7 shown, the front frame 1111 further includes a first column 1111h, and the rear frame 1113 further includes a second column 1113a. The first column 1111h and the second column 1113a are generally respectively referred to as the A-pillar and the B-pillar. The first column 1111h and the second column 1113a are used for bearing, supporting and protecting. One end of the first column 1111h is connected to the first cross beam 1112c, and the other end of the first column 1111h extends upward. One end of the second column 1113a is connected to the second cross beam 1112d, and the other end of the second column 1113a extends upward.

[0046] As Figure 7 and Figure 8As 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. Among them, 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 the longitudinal reinforcing tube 1112k on the middle frame 1112, and the other end of the first reinforcing rod 1114a is connected to the second column 1113a. The rear frame 1113 further includes a support bracket 1113y. One end of the second reinforcing rod 1114b is connected to the support bracket 1113y, and the other end of the second reinforcing rod 1114b is connected to the second column 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 is connected to the second reinforcing rod 1114b. In this way, the acting force concentrated on the second column 1113a by the first reinforcing rod 1114a and the second reinforcing rod 1114b is shared by the reinforcing plate 1114c, thereby avoiding processes such as punching holes in the second column 1113a and reducing the possibility of local deformation of the second column 1113a. It should be noted that only the connection method of the reinforcing rods at the second column 1113a is described here, and the above structure can also be applied to other columns, crossbeams, or longitudinal beams.

[0047] 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 respectively welded to the first reinforcing rod 1114a and the second reinforcing rod 1114b. Reinforcing pieces 1114d are respectively provided at both ends of the reinforcing plate 1114c. Each reinforcing piece 1114d abuts against the corresponding reinforcing rod. In this way, the contact area between the reinforcing plate 1114c and the first reinforcing rod 1114a and the second reinforcing rod 1114b is increased, and the connection strength between the reinforcing plate 1114c and the first reinforcing rod 1114a and the second reinforcing rod 1114b is improved.

[0048] As Figure 9 and Figure 10 As shown, the vehicle body 112 includes an interior trim 1122 and an exterior trim 1123. The interior trim 1122 is disposed on the vehicle frame 111 and together with the vehicle frame 111 encloses a cabin 1121. In other words, the interior trim 1122 is distributed around the cabin 1121. There is at least one first opening 1121a on one side of the cabin 1121, and the driver and passengers can enter and exit the cabin 1121 through the first opening 1121a. The exterior trim 1123 is located at the front end, rear end, and sides of the vehicle frame 111 to shield and protect the front suspension assembly 15, the rear suspension assembly 16, and various electrical components, etc.

[0049] The interior component 1122 includes a front baffle 1122a, an instrument panel 1122b, a footrest 1122c, a rear baffle 1122d, and a seat 1122f. The front baffle 1122a is disposed near the front end of the all-terrain vehicle 100 to separate the components located at the front end of the all-terrain vehicle 100 from the cabin 1121, and functions to block stones, sediment, water, etc. The instrument panel 1122b is installed at one end of the front baffle 1122a away from the ground to carry various instrument devices on the vehicle, such as a display screen, an instrument panel, etc. The footrest 1122c is installed at the bottom of the accommodation space 111a and is used as a bearing plate to carry various components such as the seat 1122f, and the positions where the feet of the driver or passengers are placed when sitting. The rear baffle 1122d is disposed near the rear end of the all-terrain vehicle 100 to separate the components located at the rear end of the all-terrain vehicle 100 from the cabin 1121. And the rear baffle 1122d is spaced apart from the front baffle 1122a, and the footrest 1122c is located between the rear baffle 1122d and the front baffle 1122a. Thus, the above-mentioned cabin 1121 is jointly formed among the three.

[0050] As Figure 11 shown, the all-terrain vehicle 100 further includes an electrical component 19 and an electronic control unit 21. Both the electrical component 17 and the electronic control element 21 are installed on the frame assembly 11, and at least part of the electrical component 19 is electrically / signal-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 (ECU, Electronic Control Unit), is also called the "vehicle computer", which is used to monitor various input data (such as braking, shifting, etc.) and various states of the vehicle operation (acceleration, skidding, fuel consumption, etc.), and calculate the information transmitted by various sensors according to a pre-designed program. After processing, each parameter is sent to each relevant actuator, such as the electrical component 19, etc., to perform various predetermined control functions.

[0051] In an embodiment, as Figure 9As shown, the electrical component 19 includes an instrument device 200 and a switch device 203. The instrument device 200 includes various electrical instruments, such as an ammeter, a charging indicator light, or a voltmeter, an oil pressure gauge, a temperature gauge, a fuel gauge, a vehicle speed and odometer, an engine speedometer, etc. The instrument device 200 is mainly used to display the working conditions of relevant devices during the driving of the all-terrain vehicle 100. The sounding device 201 is mainly used to emit sounds to play a prompting or warning role. The switch device 203 includes a mode switching switch 2031, an air conditioner switch (not shown in the figure), a temperature adjustment switch (not shown in the figure), etc. The mode switching switch 2031, the air conditioner switch, and the temperature adjustment switch are basically installed on the instrument panel 1122b for easy operation by the driver and the front passenger. The mode switching switch 2031, the air conditioner switch, the temperature adjustment switch, etc. are all electrically / signal-connected to the electronic control unit 21 through a wire harness 2042, thereby controlling a series of functions such as the switching between two-wheel drive and four-wheel drive of the all-terrain vehicle 100, the turning on of the air conditioner, and the adjustment of the air conditioner temperature.

[0052] As Figures 12 to 15 shown, the mode switching switch 2031 includes a two-wheel drive gear 2031a, a four-wheel drive gear 2031b, and a front-wheel lock gear 2031c. The four-wheel drive gear 2031b is located between the two-wheel drive gear 2031a and the front-wheel lock gear 2031c. The two-wheel drive gear 2031a realizes the two-wheel drive operation of the all-terrain vehicle 100. The four-wheel drive gear 2031b realizes the four-wheel drive operation of the all-terrain vehicle 100. The front-wheel lock realizes the locking of the front wheels of the all-terrain vehicle 100. Among them, the mode switching switch 2031 includes a housing 2031d, a pressing plate 2031x, a switch rotating 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 in the chamber 2031za. The second gear slot 2031f is located between the first gear slot 2031e and the third gear slot 2031j. The pressing plate 2031x is rotationally connected to the housing 2031d through the switch rotating shaft 2031t. One end of the gear lever unit 2031u is connected to the pressing plate 2031x, and the other end of the gear lever unit 2031u can swing with the pressing plate 2031x and switch between the first gear slot 2031e, the second gear slot 2031f, and the third gear slot 2031j, so as to realize the mutual switching between the two-wheel drive gear 2031a, the four-wheel drive gear 2031b, and the front-wheel lock gear 2031c.

[0053] Please refer to Figure 13, the gear lever unit 2031u includes a switching lever 2031v, an elastic member 2031x, and a sphere 2031y. One end of the switching lever 2031v is connected to the pressing plate 2031x and can swing within the housing 2031d under the drive of the pressing plate 2031x. A fourth mounting hole 2031w is formed at the end of the switching lever 2031v away from the pressing plate 2031x. The elastic member 2031x is installed in the fourth mounting hole 2031w. Part of the sphere 2031y is located in the fourth mounting hole 2031w and abuts against the elastic member 2031x, and the other end can swing and fall into the first gear slot 2031e, the second gear slot 2031f, or the third gear slot 2031j.

[0054] As Figure 14 and Figure 15 shown, the first gear slot 2031e, the second gear slot 2031f, and the third gear slot 2031j are all arc-shaped slots, and the first gear slot 2031e, the second gear slot 2031f, and the third gear slot 2031j are connected in sequence. The second gear slot 2031f includes a first connection end connected to the first gear slot 2031e. The first gear slot 2031e includes a second connection end connected to the first connection end. The first connection end and the second connection end intersect and have a first intersection point P and a first included angle β 1 ; the second gear slot 2031f further includes a third connection end connected to the third gear slot 2031j. The third gear slot 2031j includes a fourth connection end connected to the third connection end. The third connection end and the fourth connection end intersect and have a second intersection point Q and a second included angle β 2 ; the first included angle β 1 and the second included angle β 2 have a difference greater than or equal to 5° and less than or equal to 30°. That is, the slope of the second gear slot 2031f on the side close to the third gear slot 2031j is greater than the slope of the second gear slot 2031f on the side close to the first gear slot 2031e. The transition between the first gear slot 2031e and the second gear slot 2031f is smoother than the transition between the second gear slot 2031f and the third gear slot 2031j. In this way, when shifting gears, the damping of the switching lever 2031v switching from the second gear slot 2031f to the third gear slot 2031j can be greater than the damping of the switching lever 2031v switching from the first gear slot 2031e to the second gear slot 2031f. That is, the force values for each gear shift are different, and the force value required for the operation when shifting from the four-wheel drive gear to the front-wheel drive locked gear 2031c becomes larger, avoiding the phenomenon of overshifting directly from the two-wheel drive gear 2031a to the front-wheel drive locked gear 2031c when shifting from the two-wheel drive gear 2031a to the four-wheel drive gear 2031b, and improving the driving safety.

[0055] In one embodiment, as Figure 14As shown, along the Z direction of the axis of the chamber 2031za, the position of the second intersection point Q is relatively higher than that of the first intersection point P. Thus, in combination with the above-mentioned angles, the stroke of switching from the four-wheel drive gear 2031b to the front-wheel drive locked gear 2031c can be extended, so that the damping of the switching lever 2031v from the second gear slot 2031f to the third gear slot 2031j increases, further avoiding the over-shifting phenomenon during the switching process.

[0056] Please refer to Figure 14 and Figure 15 , the second gear slot 2031f includes a second arc segment 2031g, a first straight segment 2031h, and a second straight segment 2031i. One end of the first straight segment 2031h is connected to the first gear slot 2031e, and the other end is connected to the second arc 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 segment 2031g. The first gear slot 2031e at least includes a third straight segment 2031k, and the third gear slot 2031j at least includes a fourth straight segment 2031z. The third straight segment 2031k intersects with the first straight segment 2031h to form a first included angle β 1 , the fourth straight segment 2031z intersects with the second straight segment 2031i to form a second included angle β 2 . The first included angle β 1 is greater than or equal to 120° and less than or equal to 140°, and the second included angle β 2 is greater than or equal to 100° and less than or equal to 125°.

[0057] Furthermore, the first straight segment intersects with the plane A 1 and forms a third included angle β 3 , the second straight segment intersects with the plane A 1 and forms a fourth included angle β 4 , the difference between the fourth included angle β 4 and the third included angle β 3 is greater than or equal to 5° and less than or equal to 30°. The third included angle β 3 is greater than or equal to 45° and less than or equal to 60°, and the fourth included angle β 4 is greater than or equal to 55° and less than or equal to 75°. With such a setting, it can also make the slope of the second straight segment 2031i relative to the plane A 1 greater than the slope of the first straight segment 2031h relative to the plane A 1 . Thus, the force value required for the switching lever 2031v to switch from the second gear slot 2031f to the third gear slot 2031j will become larger.

[0058] In an embodiment, the third straight segment 2031k intersects with the plane A 1 and forms a fifth included angle β 5 ; the fourth straight segment 2031z intersects with the plane A1 intersect and form a sixth included angle β 6 , a fifth included angle β 5 and the sixth included angle β 6 are substantially the same. With such a setting, the operating force value for switching from the two-wheel drive gear 2031a to the four-wheel drive gear 2031b can be made substantially equal to the operating force value for switching from the front-wheel lock-up gear 2031c to the four-wheel drive gear 2031b, improving the consistency of operation.

[0059] As Figure 13 , Figure 16 and Figure 17 shown, the housing 2031d has output contacts 2031l that protrude from the outer surface of the housing 2031d. The output contacts 2031l are connected to the circuit boards on the corresponding switching devices 203, such as the circuit board 1981n in the mode switching switch 2031, the circuit board in the air-conditioning switch, the circuit board in the temperature adjustment switch, etc. The wiring harness 2042 has a docking head 2031n connected to the output contacts 2031l, and the docking head 2031n is connected to the output contacts 2031l, so that the switching device 203 is electrically / signal-connected to the electronic control unit 21. Among them, a connecting cover 2031m surrounding the output contacts 2031l in the circumferential direction is provided on the outer surface of the housing 2031d, and the connecting cover 2031m can be integrally provided with the housing 2031d or can be provided as a split type. A seal 2031q is provided on the connecting cover 2031m or the docking head 2031n. After the docking head 2031n and the output contacts 2031l are docked, the seal 2031q can seal the gap between the docking head 2031n and the connecting cover 2031m, so that the output contacts 2031l are in a relatively sealed state, avoiding short-circuit ablation of the output contacts 2031l and the docking head 2031n due to water or the like. At the same time, during the docking process, the connecting cover 2031m also plays a guiding role, facilitating the connection between the docking head 2031n and the output contacts 2031l and making the assembly more convenient.

[0060] In one embodiment, a second receiving groove 2031o and a second slot 2031p are formed in the docking head 2031n. A connection contact corresponding to the output contact 2031l is provided in the second receiving groove 2031o; the second slot 2031p is arranged around the second receiving groove 2031o, a seal 2031q is arranged in the second slot 2031p, and the connection cover 2031m can be inserted into the second slot 2031p and is hermetically connected to the seal 2031q. That is, not only is the sealing achieved through the seal 2031q, but also the docking head 2031n is covered on the connection 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 seal 2031q is sleeved on the outer wall of the second slot 2031p. At the same time, the seal 2031q is made of a rubber sealing ring or a silicone sealing ring. An annular sealing protrusion 2031r is provided on the outer side wall of the seal 2031q in the circumferential direction, and the sealing protrusion 2031r is in sealing contact with the inner wall of the connection cover 2031m. Here, the number of the sealing protrusions 2031r is multiple, and the multiple sealing protrusions 2031r are arranged at intervals along the axial direction of the second slot 2031p. In another embodiment, the seal 2031q can also be directly arranged on the inner wall of the connection cover 2031m, the docking head 2031n is inserted into the connection cover 2031m and abuts against the seal 2031q.

[0061] As Figure 11 shown, the electrical component 19 further includes a storage battery 1922 and an electrical connection socket unit 204. The storage battery 1922 is installed on the middle frame 1112 for storing electric energy. The electrical connection socket unit 204 is connected to the storage battery 1922 through a wire harness 2042 and is installed on the vehicle frame 111 to supply power to the modified parts of the all-terrain vehicle 100, thereby avoiding damaging the original wire harness of the all-terrain vehicle 100 during the modification process.

[0062] As Figure 18As shown, the electrical connection socket unit 204 includes a wiring socket 2021, a wiring harness 2042, a terminal 2043, and a power supply lock 2044. The terminal 2043 is connected to the storage battery through the wiring harness 2042. The power supply lock 2044 is connected between the wiring socket 2021 and the storage battery 1922, and the opening and closing of the power supply lock 2044 are interlocked with the start / stop of the all-terrain vehicle 100. That is, when the all-terrain vehicle 100 starts or is powered on, the power supply lock 2044 is opened. When the all-terrain vehicle 100 shuts down, the power supply lock 2044 is closed. Among them, the terminal 2043 includes a first type of terminal 2043a and a second type of terminal 2043b. The first type of terminal 2043a is electrically connected to the storage battery 1922 through the wiring harness 2042. The second type of terminal 2043b is electrically connected to the power supply lock 2044 through the wiring harness 2042 and is electrically connected to the storage battery 1922 through the power supply lock 2044. In this way, the electrical connection between the second type of terminal 2043b and the storage battery 1922 needs to be controlled by the power supply lock 2044. Therefore, during the process of installing aftermarket parts on the all-terrain vehicle 100, when the aftermarket parts need continuous power supply, the aftermarket parts can be connected to the corresponding first type of terminal 2043a that is not controlled by the power supply lock 2044. When the power supply of the aftermarket parts needs to be controlled by the start / stop of the all-terrain vehicle 100, the aftermarket parts can be connected to the corresponding second type of terminal 2043b that is controlled by the power supply lock 2044.

[0063] In some embodiments, such as Figures 16 to 18As 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 through a wire harness 2042, and the second terminal 2043d is connected to the negative terminal of the battery 1922, so that a continuous power supply loop is formed among the first terminal 2043c, the second terminal 2043d, and the positive and negative electrodes of the battery 1922. The power supply lock 2044 is linked with the start switch of the all-terrain vehicle 100, that is, when the all-terrain vehicle 100 starts, the power supply lock 2044 is turned on, and when the all-terrain vehicle 100 shuts down, the power supply lock 2044 is also turned off accordingly. One end of the power supply lock 2044 is connected to the positive electrode of the battery 1922, and the other end is connected to the third terminal 2043e through a wire harness 2042. When the power supply lock 2044 is turned on, the third terminal 2043e is connected to the positive electrode of the battery 1922, and when the power supply lock 2044 is turned off, the third terminal 2043e is disconnected from the positive electrode of the battery 1922. In this way, a power supply loop controlled by the power supply lock 2044 is formed among the third terminal 2043e, the power supply lock 2044, the second terminal 2043d, and the battery 1922; during the process of installing and modifying parts on the all-terrain vehicle 100, when the modified parts need continuous power supply, the modified parts can be connected to the first terminal 2043c and the second terminal 2043d. When the power supply of the modified parts needs to be controlled by the start / stop of the all-terrain vehicle 100, the wire harness of the modified parts can be connected to the second terminal 2043d and the third terminal 2043e.

[0064] In some other embodiments, as Figure 21 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 electrode of the battery 1922, and the second terminal 2043d is connected to the negative electrode of the battery 1922 to form a continuous power-taking loop; the third terminal 2043e is connected to the negative electrode of the battery 1922 through a wire harness 2042, and the fourth terminal 2043f is connected to the power supply lock 2044 through a wire harness 2042 and is connected to the positive electrode of the battery 1922 through the power supply lock 2044. In this way, a power-taking loop controlled by the power supply lock 2044 is formed. Of course, the number of the first type of terminals 2043a and the second type of terminals 2043b can be three, four or others respectively, and the connection among the terminals 2043, the power supply lock 2044, and the battery 1922 can be a combination of the above two embodiments, or one of the above two embodiments or other forms. Which one to choose specifically can be set according to actual needs and is not limited here.

[0065] AsFigure 18 and Figure 20 As shown in Figure 20 , the electrical connection seat unit 204 further includes a fuse box 2045, a wiring cover 2047, and a resistance connection partition 2046. Among them, the fuse box 2045 is arranged on the corresponding wire harness 2042 to protect the storage battery 1992 and to avoid the problem of power loss of the storage battery 1922 as much as possible. The wiring cover 2047 covers the wiring seat 2021 to protect the terminal post 2043, thereby avoiding the short-circuit phenomenon of the terminal post 2043 caused by metal falling objects. The number of the resistance connection partitions 2046 is multiple, and the multiple resistance connection partitions 2046 are arranged on the connection seat at intervals, and the wire harness 2042 between two adjacent terminal posts 2043 is isolated by the resistance connection partition 2046 to avoid the mutual influence of the wire harnesses 2042 between two adjacent terminal posts 2043. Here, the resistance connection partition 2046 and the connection seat are integrally formed.

[0066] In an embodiment, the fuse box 2045 includes a main fuse 2045a and a plurality of sub-fuses 2045b. The main fuse 2045a is arranged close to the positive pole of the storage battery 1922. One of the sub-fuses 2045b is arranged on the wire harness 2042 connecting the terminal post 2043 and the positive pole of the storage battery 1922, and the other sub-fuse 2045b is arranged on the wire harness 2042 connecting the terminal post 2043 and the power lock 2044. In this embodiment, the main fuse 2045a and the sub-fuse 2045b arranged on the wire harness 2042 connecting the terminal post 2043 and the positive pole of the storage battery 1922 are connected in series, so as to achieve double protection and further avoid the problem of power loss of the storage battery 1922.

[0067] As Figure 18 shown in Figure 18 , the wire harness 2042 includes a first wire harness 2042a and a second wire harness 2042c. One end of the first wire harness 2042a is connected to the terminal post 2043, and a male wiring terminal 2042b is arranged at the other end of the first wire harness 2042a. One end of the second wire harness 2042c is connected to the storage battery 1922, and a female wiring terminal 2042d is arranged at the other end of the second wire harness 2042c. Among them, the male wiring terminal 2042b is inserted into the female wiring terminal 2042d, so as to realize the electrical connection between the wiring seat 2021 and the storage battery 1922. In this way, the wire harnesses 2042 on the wiring seat 2021 and the storage battery 1922 are integrated, and the wiring between the two is very simple and convenient.

[0068] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope recorded in this specification.

[0069] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
