[0038] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] like Figure 1 As shown, the present application provides an all-terrain vehicle 100. As a universal tool, the all-terrain vehicle 100 can be normally driven in many areas such as beaches, hillsides, and deserts. In order to clearly explain the structure of the all-terrain vehicle 100, the present application Figure 1 The front, rear, top, bottom, left, and right sides of the ATV 100 are defined in the figure. The ATV 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 ATV 100 and withstanding various loads from both inside and outside the vehicle. The suspension assembly 22 is mounted on the frame assembly 11 and supports the wheel assembly 23, thereby cushioning impact forces transmitted to the frame assembly 11 from uneven road surfaces, reducing the resulting vibration and ensuring smooth and stable travel for the ATV 100.

[0040] 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. It is 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 impact forces transmitted to the frame assembly 11 from uneven roads, etc., thereby reducing the resulting vibration. The rear suspension assembly 16 is located 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 forces acting between the rear wheel set 18 and the frame assembly 11. Furthermore, the rear suspension assembly 16 and the front suspension assembly 15 can buffer impact forces transmitted to the frame assembly 11 from uneven roads, etc., thereby reducing the resulting vibration.

[0041] The vehicle frame assembly 11 comprises a frame 111 and a body 112. The frame 111 utilizes a frame-like structure and serves as a base structure to carry various loads inside and outside the vehicle. The front suspension assembly 15 and the rear suspension assembly 16 are mounted to the front and rear ends of the frame 111, respectively. The layout of the front and rear suspension assemblies 15, 16 on the frame 111 can be customized as needed, but this will not be discussed in detail here. The body 112 is mounted on the frame 111 and at least partially encloses it, thereby protecting its components. The body 112 also serves as the driver's driving position and as a space for passengers and cargo.

[0042] like Figures 2 to 3 As shown, 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 house components located at the front end, such as the front suspension assembly 15, headlights, and a radiator. The rear frame 1113 is located at the rear end of the all-terrain vehicle 100 to carry or house components located at the rear end, 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 the middle frame 1112. The front frame 1111, middle frame 1112, and rear frame 1113 surround and form a housing 111a. The vehicle body 112 covers the frame 111 and is provided with a cabin 1121. The cabin 1121 serves as a cockpit and / or passenger compartment for the driver or passengers. The cabin 1121 can be partially embedded in the accommodating space 111 a and installed on the vehicle frame 111 , so that the cabin 1121 can obtain a larger usable space when the height of the all-terrain vehicle 100 meets the standard.

[0043] like Figures 4 to 6As shown, the middle frame 1112 serves as a structure that bears the core load of the all-terrain vehicle 100. 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 one embodiment, the number of the first type of beam 1112a is multiple, and the multiple first type beams 1112a are arranged at intervals and are basically located in the same plane. Here, the plane where the first type beam 1112a is located is set as plane S. The number of the second type beam 1112b is also multiple, and the multiple second type beams 1112b are arranged at intervals between the multiple first type beams 1112a. It can be understood that the number of the first type beam 1112a can be set to two, three or four. Similarly, the number of the second type beam 1112b Of course, the specific number of the first type beams 1112a and the specific number of the second type beams 1112b can be selected according to actual conditions, and will not be described in detail here.

[0044] In this embodiment, the first type of beam 1112a includes a first transverse beam 1112c and a second transverse beam 1112d. The second type of beam 1112b includes a first longitudinal beam 1112e and a second longitudinal beam 1112h. Along the front-to-back direction of the all-terrain vehicle 100, the first longitudinal beam 1112e is positioned near the front end, while the second longitudinal beam 1112h is positioned 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 transverse beam 1112c, and the other end of the first rod 1112f extends toward the second transverse beam 1112d. The angle A1 between the first rod 1112f and plane S 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 transverse beam 1112d, and the other end of the second rod 1112g extends toward the first transverse beam 1112c and is connected to the first rod 1112f. The angle A2 between the second rod 1112g and plane S is set to be greater than or equal to 5° and less than or equal to 15°. This allows the bottom of the mid-frame 1112 to appear to be raised upward (away from the driving surface) along the front-to-rear direction of the ATV 100. In other words, the bottom of the mid-frame 1112 is raised upward. This increases the ground clearance of the ATV 100 at the mid-frame 1112, effectively improving the vehicle's maneuverability during travel.

[0045] In one embodiment, the angle A1 between the first rod 1112f and plane S is greater than the angle A2 between the second rod and plane S. This allows the all-terrain vehicle 100 to maintain good maneuverability when traversing continuously uneven surfaces. Furthermore, the first-type beam 1112a and the second-type beam 1112b are each formed from cut 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 of the second-type beam 1112b are arranged parallel to each other, and the second rods 1112g of the second-type 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, with one end connected to the first beam 1112c and the other end extending toward the second beam 1112d. The fourth rod 1112j is parallel to the second rod 1112g, with one end connected to the second beam 1112d and the other end extending toward the first beam 1112c and connected to the third rod 1112i.

[0046] like Figure 5 As shown, the midframe 1112 also includes longitudinal reinforcement tubes 1112k and transverse reinforcement tubes 1112l. There are at least two longitudinal reinforcement tubes 1112k. In this embodiment, two longitudinal reinforcement tubes 1112k are used as an example to specifically describe the location and installation of the longitudinal reinforcement tubes 1112k. The two longitudinal reinforcement tubes 1112k are spaced apart, with the second-type beam 1112b located between the two longitudinal reinforcement tubes 1112k. One end of each longitudinal reinforcement tube 1112k is fixed to the first transverse beam 1112c, and the other end is fixed to the second transverse beam 1112d. The transverse reinforcement tubes 1112l are located between the longitudinal beams 1112b and the corresponding longitudinal reinforcement tubes 1112k. One end of the transverse reinforcement tube 1112l is connected to the longitudinal beam, and the other end of the transverse reinforcement tube 1112l is connected to the longitudinal beam. Thus, the longitudinal reinforcement tube 1112k, the transverse reinforcement tube 1112l, the crossbeam 1112a and the longitudinal beam 1112b together form a mesh-like structure, effectively improving the structural strength and load-bearing capacity of the entire middle frame 1112.

[0047] like Figure 7As shown, the front frame 1111 also includes a first pillar 1111h, and the rear frame 1113 also includes a second pillar 1113a. The first pillar 1111h and the second pillar 1113a are commonly referred to as the A-pillar and the B-pillar, respectively. The first pillar 1111h and the second pillar 1113a serve as load-bearing, support, and protection. One end of the first pillar 1111h is connected to the first crossbeam 1112c, and the other end of the first pillar 1111h extends upward. One end of the second pillar 1113a is connected to the second crossbeam 1112d, and the other end of the second pillar 1113a extends upward.

[0048] like Figure 7 and Figure 8 As shown, in one embodiment, to enhance the structural strength of the connection between the rear frame 1113 and the middle frame 1112, a reinforcement structure 1114 is provided between the rear frame 1113 and the middle frame 1112. The reinforcement structure 1114 includes a first reinforcement rod 1114a, a second reinforcement rod 1114b, and a reinforcement plate 1114c. One end of the first reinforcement rod 1114a is connected to a longitudinal reinforcement tube 1112k on the middle frame 1112, and the other end of the first reinforcement rod 1114a is connected to the second column 1113a. The rear frame 1113 also includes a support bracket 1113y. One end of the second reinforcement rod 1114b is connected to the support bracket 1113y, and the other end of the second reinforcement rod 1114b is connected to the second column 1113a. One end of reinforcement plate 1114c is connected to first reinforcement rod 1114a. The other end of reinforcement plate 1114c extends toward the rear end of ATV 100, spanning second column 1113a and connecting to second reinforcement rod 1114b. In this way, reinforcement plate 1114c distributes the forces concentrated on second column 1113a by first and second reinforcement rods 1114a, 1114b, thereby avoiding processes such as drilling holes in second column 1113a and reducing the possibility of local deformation of second column 1113a. It should be noted that this description only describes the reinforcement rod connection method for second column 1113a; the above structure can also be applied to other columns, crossbeams, or longitudinal beams.

[0049] 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 each end of the reinforcing plate 1114c. Each reinforcing piece 1114d abuts against a corresponding reinforcing rod. This increases the contact area between the reinforcing plate 1114c and the first and second reinforcing rods 1114a, 1114b, thereby improving the connection strength between the reinforcing plate 1114c and the first and second reinforcing rods 1114a, 1114b.

[0050] like Figure 9 and Figure 10 As shown, the vehicle body 112 includes interior trim 1122 and exterior trim 1123. The interior trim 1122 is arranged on the frame 111 and, together with the frame 111, forms a cabin 1121. In other words, the interior trim 1122 is distributed around the cabin 1121. The cabin 1121 has at least one first opening 1121a on one side, through which the driver and passengers can enter and exit the cabin 1121. The exterior trim 1123 is located at the front, rear, and sides of the frame 111 to shield and protect the front suspension assembly 15, rear suspension assembly 16, and various electrical components.

[0051] The interior components 1122 include a front fender 1122a, an instrument panel 1122b, footrests 1122c, a tailgate 1122d, and a seat 1122f. The front fender 1122a is located near the front of the ATV 100, separating the front components from the cabin 1121 and acting as a barrier against rocks, mud, sand, and water. The instrument panel 1122b is mounted on the end of the front fender 1122a that is away from the ground and supports various instrumentation components, such as the display screen and instrument panel. The footrests 1122c are mounted at the bottom of the accommodating space 111a and serve as a support plate for various components, such as the seat 1122f, and as a footrest for the driver or passengers. The tailgate 1122d is located near the rear of the ATV 100, separating the rear components from the cabin 1121. 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. In this way, the three together surround and form the cabin 1121.

[0052] like Figure 11 As shown, ATV 100 also includes an electrical assembly 19 and an electronic control unit 21. Both electrical assembly 19 and electronic control unit 21 are mounted on frame assembly 11, and at least a portion of electrical assembly 19 is electrically and signal-connected to electronic control unit 21 to implement the basic electrical functions of ATV 100. Electronic control unit 21, or ECU (Electronic Control Unit), also known as a "vehicle computer," monitors various input data (such as braking and shifting) and vehicle operating conditions (acceleration, slippage, fuel consumption, etc.). It calculates information transmitted by various sensors according to pre-designed programs, processes the information, and transmits the parameters to relevant actuators, such as electrical assembly 19, to perform various predetermined control functions.

[0053] In one embodiment, if Figure 9As shown, the electrical assembly 19 includes instrumentation 200 and switch components 203. Instrumentation 200 includes various electrical instruments, such as an ammeter, a charging indicator light or voltmeter, an oil pressure gauge, a temperature gauge, a fuel gauge, a speedometer, an odometer, and an engine tachometer. Instrumentation 200 primarily displays the operating status of relevant devices while the ATV 100 is in motion. The sound-generating device 201 primarily emits sounds to provide prompts or warnings. Switch components 203 include a mode switch 2031, an air conditioning switch (not shown), and a temperature control switch (not shown). The mode switch 2031, air conditioning switch, and temperature control switch are generally mounted on the instrument panel 1122b for easy operation by the driver and front passenger. These switches are electrically and signal-connected to the electronic control unit 21 via a wiring harness 2042, thereby controlling a range of functions of the ATV 100, including switching between two-wheel drive and four-wheel drive, turning on the air conditioning, and adjusting the air conditioning temperature.

[0054] like Figures 12 to 15 As shown, the mode switch 2031 includes a two-wheel drive (2WD) position 2031a, a four-wheel drive (4WD) position 2031b, and a front-wheel drive (FWD) lock position 2031c. The four-wheel drive (4WD) position 2031b is located between the two-wheel drive (2WD) position 2031a and the front-wheel drive (FWD) lock position 2031c. The two-wheel drive (2WD) position 2031a enables the ATV 100 to operate in two-wheel drive mode. The four-wheel drive (4WD) position 2031b enables the ATV 100 to operate in four-wheel drive mode. The front-wheel drive (FWD) lock position locks the front wheels of the ATV 100. The mode switch 2031 includes a housing 2031d, a push button 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 housing 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 to switch between the first gear slot 2031e, the second gear slot 2031f, and the third gear slot 2031j, thereby achieving mutual switching between the two-wheel drive gear position 2031a, the four-wheel drive gear position 2031b, and the front-wheel drive lock gear position 2031c.

[0055] Please refer to Figure 13The 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 in the housing 2031d under the drive of the pressing plate 2031x. A fourth mounting hole 2031w is opened at the end of the switching lever 2031v away from the pressing plate 2031x, and 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. The other end can swing and fall into the first gear slot 2031e, the second gear slot 2031f or the third gear slot 2031j.

[0056] like Figure 14 and Figure 15 As 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 connecting end connected to the first gear slot 2031e, and 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 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 angle β2. The difference between the first angle β1 and the second angle β2 is greater than or equal to 5° and less than or equal to 30°. That is, the slope of the second gear slot 2031f close to the third gear slot 2031j is greater than the slope of the second gear slot 2031f close to the first gear slot 2031e, and the transition between the first gear slot 2031e and the second gear slot 2031f is smoother than the transition between the second gear slot 2031f and the third gear slot 2031j. In this way, when switching gears, the damping of the switching rod 2031v switching from the second gear slot 2031f to the third gear slot 2031j can be greater than the damping of the switching rod 2031v switching from the first gear slot 2031e to the second gear slot 2031f, that is, the force value for switching each gear is different, and the force value required for the operation from the four-wheel drive gear to the front-wheel drive lock gear 2031c becomes larger, avoiding the phenomenon of over-shifting when switching from the two-wheel drive gear 2031a to the four-wheel drive gear 2031b, thereby improving driving safety.

[0057] In one embodiment, if Figure 14As shown, along the axis Z direction of the chamber 2031za, the position of the second intersection Q is relatively higher than the position of the first intersection P. Thus, combined with the aforementioned angles, the travel of the four-wheel drive gear 2031b to switch to the front-wheel drive lock gear 2031c can be extended, thereby increasing the damping when the switching lever 2031v switches from the second gear slot 2031f to the third gear slot 2031j, further preventing over-shifting during the switching process.

[0058] Please refer to Figure 14 and Figure 15 The second shift groove 2031f includes a second curved 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 shift groove 2031e, and the other end is connected to the second curved segment 2031g. The second straight segment 2031i is connected to the third shift groove 2031j at one end, and the other end is connected to the second curved segment 2031g. The first shift groove 2031e includes at least a third straight segment 2031k, and the third shift groove 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 angle β1, and the fourth straight segment 2031z intersects with the second straight segment 2031i to form a second angle β2. The first angle β1 is greater than or equal to 120° and less than or equal to 140°, and the second angle β2 is greater than or equal to 100° and less than or equal to 125°.

[0059] Furthermore, the first straight segment intersects with plane A1 to form a third angle β3, and the second straight segment intersects with plane A1 to form a fourth angle β4. The difference between the fourth angle β4 and the third angle β3 is greater than or equal to 5° and less than or equal to 30°. The third angle β3 is greater than or equal to 45° and less than or equal to 60°, and the fourth 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 to shift the switch lever 2031v from the second gear slot 2031f to the third gear slot 2031j is greater.

[0060] In one embodiment, the third straight segment 2031k intersects with plane A1 to form a fifth angle β5; the fourth straight segment 2031z intersects with plane A1 to form a sixth angle β6, with the fifth angle β5 and the sixth angle β6 being substantially the same. This arrangement ensures that the operating force required to switch from the two-wheel drive gear position 2031a to the four-wheel drive gear position 2031b is substantially equal to the operating force required to switch from the front-wheel drive lock gear position 2031c to the four-wheel drive gear position 2031b, thereby improving operational consistency.

[0061] like Figure 13 、 Figure 16 and Figure 17As shown, the housing 2031d has output contacts 2031l protruding from the outer surface of the housing 2031d. The output contacts 2031l are connected to circuit boards on corresponding switch devices 203, such as the circuit board 1981n within the mode switch 2031, the circuit board within the air conditioning switch, or the circuit board within the temperature control switch. The wiring harness 2042 has a docking connector 2031n connected to the output contacts 2031l. The docking connector 2031n is connected to the output contacts 2031l, thereby establishing an electrical / signal connection between the switch devices 203 and the electronic control unit 21. The outer surface of the housing 2031d has a connection cover 2031m surrounding the output contacts 2031l. The connection cover 2031m can be integral with the housing 2031d or separate from it. A seal 2031q is provided on either the connection cover 2031m or the docking connector 2031n. After the docking connector 2031n is docked with the output contact 2031l, the seal 2031q seals the gap between the docking connector 2031n and the connection cover 2031m, ensuring a relatively sealed state for the output contact 2031l. This prevents short-circuiting and erosion between the output contact 2031l and the docking connector 2031n due to water or other factors. Furthermore, the connection cover 2031m also serves as a guide during the docking process, facilitating the connection between the docking connector 2031n and the output contact 2031l and facilitating assembly.

[0062] In one embodiment, the docking connector 2031n is provided with a second receiving groove 2031o and a second slot 2031p. The second receiving groove 2031o houses connection contacts corresponding to the output contacts 2031l. The second slot 2031p surrounds the second receiving groove 2031o, and a sealing member 2031q is disposed within the second slot 2031p. The connecting cover 2031m is pluggable into the second slot 2031p and sealedly connected to the sealing member 2031q. This not only achieves sealing through the sealing member 2031q, but the docking connector 2031n also covers the connecting cover 2031m, increasing the sealing path and enhancing the sealing effect. The second receiving groove 2031o and the second slot 2031p are concentrically disposed. The sealing member 2031q is sleeved onto the outer wall of the second slot 2031p. The sealing member 2031q is configured as a rubber or silicone sealing ring. An annular sealing protrusion 2031r is circumferentially provided on the outer wall of the sealing member 2031q. The sealing protrusion 2031r seals against the inner wall of the connecting cover 2031m. Here, there are multiple sealing protrusions 2031r, spaced axially along the second slot 2031p. In another embodiment, the sealing member 2031q can be directly provided on the inner wall of the connecting cover 2031m, with the butt joint 2031n inserted into the connecting cover 2031m and abutting against the sealing member 2031q.

[0063] like Figure 11As shown, electrical assembly 19 includes a battery 1922 and an electrical connector unit 204. Battery 1922 is mounted on midframe 1112 and stores electricity. Connector unit 204 is connected to battery 1922 via a wiring harness 2042 and mounted on frame 111 to power the modified parts of ATV 100, thereby preventing damage to the original wiring harness of ATV 100 during the modification process.

[0064] like Figure 18 As shown, the electrical connector unit 204 includes a connector 2021, a wiring harness 2042, terminals 2043, and a power lock 2044. Terminals 2043 are connected to the battery via the wiring harness 2042. The power lock 2044 is connected between the connector 2021 and the battery 1922, and the opening and closing of the power lock 2044 is linked to the opening and closing of the ATV 100. Specifically, when the ATV 100 is started or powered on, the power lock 2044 is opened. When the ATV 100 is turned off, the power lock 2044 is closed. The terminals 2043 include first-type terminals 2043a and second-type terminals 2043b. The first-type terminals 2043a are electrically connected to the battery 1922 via the wiring harness 2042, while the second-type terminals 2043b are electrically connected to the power lock 2044 via the wiring harness 2042, and then to the battery 1922 via the power lock 2044. Thus, the electrical connection between the second-type terminal 2043b and the battery 1922 needs to be controlled by the power lock 2044. Therefore, when adding a modified part (aftermarket part) to the ATV 100, if the modified part requires continuous power, the modified part can be connected to the corresponding first-type terminal 2043a that is not controlled by the power lock 2044. If the power supply of the modified part needs to be controlled by the start / stop of the ATV 100, the modified part can be connected to the corresponding second-type terminal 2043b that is controlled by the power lock 2044.

[0065] In some embodiments, 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. First terminal 2043c is connected to the positive terminal of battery 1922 via wiring harness 2042, while second terminal 2043d is connected to the negative terminal of battery 1922. This creates a continuous power supply circuit between first terminal 2043c, second terminal 2043d, and the positive and negative terminals of battery 1922. The power lock 2044 is linked to the start switch of ATV 100. That is, when ATV 100 is started, power lock 2044 is activated, and when ATV 100 is turned off, power lock 2044 is deactivated. One end of power lock 2044 is connected to the positive terminal of battery 1922, and the other end is connected to third terminal 2043e via wiring harness 2042. When power lock 2044 is on, third terminal 2043e connects to the positive terminal of battery 1922. When power lock 2044 is off, third terminal 2043e is disconnected from the positive terminal of battery 1922. Thus, third terminal 2043e, power lock 2044, second terminal 2043d, and battery 1922 form a power supply circuit controlled by power lock 2044. During the installation of a modified accessory on ATV 100, if continuous power is required, the accessory can be connected to first terminal 2043c and second terminal 2043d. If power supply to the modified accessory needs to be controlled by the on / off function of ATV 100, the accessory's wiring harness can be connected to second terminal 2043d and third terminal 2043e.

[0066] In other embodiments, Figure 21 As shown, first-type terminal 2043a includes first terminal 2043c and second terminal 2043d, while second-type terminal 2043b includes third terminal 2043e and fourth terminal 2043f. First terminal 2043c is connected to the positive terminal of battery 1922, and second terminal 2043d is connected to the negative terminal of battery 1922, forming a continuous power supply circuit. Third terminal 2043e is connected to the negative terminal of battery 1922 via wiring harness 2042, and fourth terminal 2043f is connected to power lock 2044 via wiring harness 2042, and then to the positive terminal of battery 1922 via power lock 2044. This forms a power supply circuit controlled by power lock 2044. Of course, the number of the first type of terminals 2043a and the second type of terminals 2043b can be three, four or more respectively. The connection between the terminals 2043 and the power lock 2044 and the battery 1922 can be a combination of the above two embodiments, or one of the above two embodiments or other forms. The specific choice can be set according to actual needs and is not limited here.

[0067] like Figure 18 and Figure 20 As shown, the electrical connector unit 204 also includes a fuse box 2045, a wiring cover 2047, and a blocking plate 2046. The fuse box 2045 is provided on the corresponding wiring harness 2042 to protect the battery 1992 and to minimize power supply problems with the battery 1922. The wiring cover 2047 is provided on the wiring base 2021 to protect the terminal 2043 and thereby prevent metal falling objects from causing a short circuit in the terminal 2043. There are multiple blocking plates 2046, and the multiple blocking plates 2046 are provided at intervals on the connector. Adjacent two terminal 2043 are isolated by the blocking plates 2046 to prevent the wiring harness 2042 between adjacent terminal 2043 from interfering with each other. Here, the blocking plates 2046 and the connector are integrated.

[0068] In one embodiment, fuse box 2045 includes a main fuse 2045a and multiple sub-fuses 2045b. Main fuse 2045a is located near the positive terminal of battery 1922. One sub-fuses 2045b is located on the wiring harness 2042 connecting terminal 2043 to the positive terminal of battery 1922. Another sub-fuses 2045b is located on the wiring harness 2042 connecting terminal 2043 to the power lock 2044. In this embodiment, main fuse 2045a and sub-fuses 2045b located on the wiring harness 2042 connecting terminal 2043 to the positive terminal of battery 1922 are arranged in series, thereby providing dual protection and further preventing power supply problems to battery 1922.

[0069] like Figure 18 As shown, wiring harness 2042 includes a first wiring harness 2042a and a second wiring harness 2042c. One end of first wiring harness 2042a is connected to terminal 2043, and the other end of first wiring harness 2042a is provided with a male terminal 2042b. One end of second wiring harness 2042c is connected to battery 1922, and the other end of second wiring harness 2042c is provided with a female terminal 2042d. Male terminal 2042b plugs into female terminal 2042d, thereby achieving electrical connection between terminal block 2021 and battery 1922. This integration of wiring harness 2042 on terminal block 2021 and battery 1922 makes wiring between the two very simple and convenient.
