[0036] In this embodiment, along the left-right direction of the all-terrain vehicle 100, the first main beam 1151 is located to the left of the second main beam 1152, the third main beam 1161 is located to the left of the fourth main beam 1162, the first pipe 1111 is located to the left of the second pipe 1112, the third pipe 1121 is located to the left of the fourth pipe 1122, the fifth pipe 1131 is located to the left of the sixth pipe 1132, and the ninth pipe 1141 is located to the left of the tenth pipe 1142.

With the above configuration, the first pillar 111, the second pillar 112, the third pillar 113, the fourth pillar 114, the upper main beam 115, and the lower main beam 116 constitute the basic frame of the vehicle frame 11, thereby improving the strength of the vehicle frame 11. Furthermore, by optimizing the structure of the first pillar 111, the second pillar 112, the third pillar 113, the fourth pillar 114, the upper main beam 115, and the lower main beam 116, that is, by replacing tubular components with sheet metal structures, the number of tubular components in the vehicle frame 11 is reduced, thereby reducing the weight of the all-terrain vehicle 100 and achieving lightweighting of both the vehicle frame 11 and the all-terrain vehicle 100.

[0037] As one implementation, the all-terrain vehicle 100 includes a symmetry plane 101 perpendicular to the left-right direction, and the all-terrain vehicle 100 is basically symmetrical about the symmetry plane 101. The frame 11 is also basically symmetrical about the symmetry plane 101.

[0038] like Figure 1 , Figures 4 to 6As shown, in one implementation, the saddle assembly 15 includes a saddle 151 and a backrest mechanism 152. The saddle 151 is at least partially mounted on the frame 11, and the backrest mechanism 152 is at least partially mounted on the frame 11, with the backrest mechanism 152 at least partially located behind the saddle 151. The backrest mechanism 152 includes a backrest 1521, a seat cushion 1522, a frame 1523, a mounting bracket 1524, and a cushioning mechanism 1525. The backrest 1521 is at least partially mounted on the frame 1523 and provides back support for the passenger. The seat cushion 1522 is at least partially mounted on the mounting bracket 1524 and provides body support for the passenger. The frame 1523 and the mounting bracket 1524 are connected via the cushioning mechanism 1525. The frame 1523 is used to mount the backrest 1521, allowing the backrest 1521 to be stably connected to the frame 1523. Mounting bracket 1524 is used to mount seat cushion 1522, so that seat cushion 1522 can be stably connected to mounting bracket 1524.

[0039] In one implementation, the frame 1523 is provided with a plurality of first mounting points 1523a, which are used to mount the backrest 1521. The plurality of first mounting points 1523a are at least partially located on both sides of the frame 1523. The frame 1523 includes a first frame 1523b, a second frame 1523c, and a third frame 1523d. The first frame 1523b and the second frame 1523c are connected via the third frame 1523d. The first frame 1523b, the second frame 1523c, and the third frame 1523d are integrally formed. Specifically, several first mounting points 1523a are at least partially located on the left and / or right side of the first frame 1523b, several first mounting points 1523a are at least partially located on the left and / or right side of the second frame 1523c, and several first mounting points 1523a are at least partially located on the upper and / or lower side of the third frame 1523d, thereby achieving a stable connection between the backrest 1521 and the frame 1523.

[0040] In one implementation, the mounting bracket 1524 is provided with a plurality of second mounting points 1524a, which are used to mount the seat cushion 1522. The plurality of second mounting points 1524a are located on both sides of the mounting bracket 1524. The mounting bracket 1524 includes a first bracket 1524b, a second bracket 1524d, a third bracket 1524e, and a fourth bracket 1524f. The first bracket 1524b extends substantially along the front-rear direction of the all-terrain vehicle 100, the second bracket 1524d extends substantially along the front-rear direction of the all-terrain vehicle 100, the third bracket 1524e extends substantially along the left-right direction of the all-terrain vehicle 100, and the fourth bracket 1524f extends substantially along the left-right direction of the all-terrain vehicle 100. Several second mounting points 1524a are at least partially disposed on the first bracket 1524b, and several second mounting points 1524a are at least partially disposed on the second bracket 1524d, thereby achieving a stable connection between the seat cushion 1522 and the mounting bracket 1524. Specifically, the first bracket 1524b is provided with a first connector 1524h, and the second bracket 1524d is provided with a second connector 1524j. Several third mounting points 1524k are provided on both the first connector 1524h and the second connector 1524j. The several third mounting points 1524k are used to mount the seat cushion 1522, thereby achieving a stable connection between the seat cushion 1522 and the first connector 1524h, and a stable connection between the seat cushion 1522 and the second connector 1524j. The first connector 1524h can be disposed on the left / right side of the first bracket 1524b, and the second connector 1524j can be disposed on the left / right side of the second bracket 1524d. Specifically, the third bracket 1524e is at least partially disposed between the first bracket 1524b and the second bracket 1524d, with one end of the third bracket 1524e connected to the first bracket 1524b and the other end connected to the second bracket 1524d; the fourth bracket 1524f is at least partially disposed between the first bracket 1524b and the second bracket 1524d, with one end of the fourth bracket 1524f connected to the first bracket 1524b and the other end connected to the second bracket 1524d. This arrangement makes the structure of the mounting bracket 1524 more stable, thereby making the structure of the backrest mechanism 152 more stable. Furthermore, the fourth bracket 1524f is also used to mount the buffer mechanism 1525. In this embodiment, weight-reducing holes are provided on the first bracket 1524b, the second bracket 1524d, and the third bracket 1524e. These holes are used to make the mounting bracket 1524 lighter, thereby improving the overall weight reduction of the all-terrain vehicle 100.

[0041] In one implementation, the buffer mechanism 1525 includes a limiting member 1525a and a buffer member 1525n. The limiting member 1525a is disposed on the fourth support 1524f and is used to limit the rotation angle of the frame 1523. The limiting member 1525a includes a first limiting member 1525b, a second limiting member 1525c, a third connecting member 1525e, and a fourth connecting member 1525g. The buffer member 1525n is disposed on the fourth support 1524f and at least partially disposed between the first limiting member 1525b and the second limiting member 1525c. The buffer member 1525n is elastic and is used to provide elastic cushioning, thereby reducing the impact force of the backrest 1521 on the passenger. Through the above arrangement, the backrest mechanism 152 can provide elastic cushioning through the buffer member 1525n when the all-terrain vehicle 100 is in motion, reducing the impact force of the backrest mechanism 152 on the passenger, thereby improving the comfort and safety of the all-terrain vehicle 100. Furthermore, the connection between the buffer 1525n and the fourth bracket 1524f can be achieved by bolting, riveting, or welding. Specifically, the connection method between the buffer 1525n and the fourth bracket 1524f can be adjusted according to actual needs.

[0042] The third connector 1525e is used to connect the first limiting member 1525b and the first skeleton 1523b, and the third connector 1525e and the first limiting member 1525b are rotatably connected. The fourth connector 1525g is used to connect the second limiting member 1525c and the second skeleton 1523c, and the fourth connector 1525g and the second limiting member 1525c are rotatably connected. Specifically, one end of the third connector 1525e is provided with a first receiving groove 1525f, and one end of the first skeleton 1523b is at least partially disposed in the first receiving groove 1525f, and the first skeleton 1523b and the first receiving groove 1525f are connected; one end of the fourth connector 1525g is provided with a second receiving groove 1525h, and one end of the second skeleton 1523c is at least partially disposed in the second receiving groove 1525h, and the second skeleton 1523c and the second receiving groove 1525h are connected. The first frame 1523b and the first receiving groove 1525f can be connected by welding, and the second frame 1523c and the second receiving groove 1525h can also be connected by welding. Specifically, both the first receiving groove 1525f and the second receiving groove 1525h are provided with a fourth mounting point 1525k, and both the first limiting member 1525b and the second limiting member 1525c are provided with a fifth mounting point 1525m. The fourth mounting points 1525k and 1525m are used for the rotational connection between the first limiting member 1525b and the third connecting member 1525e, and also for the rotational connection between the second limiting member 1525c and the fourth connecting member 1525g.

[0043] In this embodiment, a limiting groove 1525d is provided on the first limiting member 1525b, and a limiting piece 1525j is provided at the other end of the third connecting member 1525e; a limiting groove 1525d is provided on the second limiting member 1525c, and a limiting piece 1525j is provided at the other end of the fourth connecting member 1525g. The limiting piece 1525j is at least partially disposed in the limiting groove 1525d, which limits the range of movement of the limiting piece 1525j, thereby controlling the rotation range of the third connecting member 1525e relative to the first limiting member 1525b, and controlling the rotation range of the fourth connecting member 1525g relative to the second limiting member 1525c, and further controlling the rotation range of the backrest 1521 and the frame 1523. The limiting groove 1525d includes a first extreme position and a second extreme position. Along the longitudinal direction of the all-terrain vehicle 100, the first extreme position is at least partially located behind the second extreme position. When the limiting piece 1525j abuts against the first extreme position, the frame 1523 is at a first angle relative to the mounting bracket 1524; when the limiting piece 1525j abuts against the second extreme position, the frame 1523 is at a second angle relative to the mounting bracket 1524. The first angle and the second angle constitute a rotation angle α. That is, the frame 1523 rotates relative to the mounting bracket 1524 between the first angle and the second angle. Through the above setting, the rotation angle α of the backrest 1521 and the frame 1523 can be limited to a certain rotation range, thereby improving the safety of the backrest 1521 and the frame 1523 while satisfying the buffering rotation of the backrest 1521 and the frame 1523. Specifically, the rotation angle α is greater than or equal to 0° and less than or equal to 60°. In this embodiment, the rotation angle α is greater than or equal to 0° and less than or equal to 15°. It can be understood that the rotation angle α can also be greater than or equal to 0° and less than or equal to 10°.

[0044] Specifically, the buffer mechanism 1525 further includes a buffer rod 1525r. The buffer rod 1525r is at least partially disposed between the third connector 1525e and the fourth connector 1525g, with one end of the buffer rod 1525r connected to the third connector 1525e and the other end connected to the fourth connector 1525g. In this embodiment, one end of the buffer rod 1525r is welded to the third connector 1525e, and the other end is welded to the fourth connector 1525g. The buffer member 1525n includes an integrally formed mounting portion and a connecting portion. The mounting portion is used to connect the buffer member 1525n and the fourth bracket 1524f, and the connecting portion abuts or contacts the buffer rod 1525r. In this embodiment, the connecting portion is elastic, so that under the force of the buffer rod 1525r, the connecting portion can rotate relative to the mounting portion. Along the front-rear direction of the all-terrain vehicle 100, the buffer bar 1525r is set on the front side of the connecting part, so that the connecting part can rotate relative to the mounting part under the force of the buffer bar 1525r.

[0045] In this embodiment, the buffer rod 1525r and the buffer member 1525n have a first position of mutual abutment and a second position of mutual contact. When the buffer rod 1525r is in the first position relative to the buffer member 1525n, the force exerted by the buffer member 1525n on the buffer rod 1525r is a first force; when the buffer rod 1525r is in the second position relative to the buffer member 1525n, the force exerted by the buffer member 1525n on the buffer rod 1525r is a second force. The first force is greater than the second force. Specifically, when the frame 1523 is at a first angle relative to the mounting bracket 1524, the buffer rod 1525r is in the second position of mutual contact with the buffer member 1525n; when the frame 1523 is at a second angle relative to the mounting bracket 1524, the buffer rod 1525r is in the first position of mutual abutment with the buffer member 1525n. With the above settings, the contact position of the limiting piece 1525j and the limiting groove 1525d can be changed by the cooperation of the buffer rod 1525r and the buffer piece 1525n, thereby changing the angle of the frame 1523 relative to the mounting bracket 1524, and thus limiting the rotation angle α of the backrest 1521 and the frame 1523 to a certain range of rotation.

[0046] In one implementation, a first latching member 1524c is provided at one end of the third bracket 1524e, and a first latching member 1524c is also provided at the other end of the third bracket 1524e. A second latching member 1524g is provided at one end of the fourth bracket 1524f, and a second latching member 1524g is also provided at the other end of the fourth bracket 1524f. Specifically, the first latching member 1524c is located on the lower side of the third bracket 1524e, and the second latching member 1524g is located on the lower side of the fourth bracket 1524f. The first latching member 1524c is located on the front side of the second latching member 1524g.

[0047] like Figure 6As shown, the mounting bracket assembly 16 includes a first mounting bracket 161, which extends substantially in a left-right direction. The first mounting bracket 161 is at least partially disposed between the first main beam 1151 and the second main beam 1152, with one end connected to the first main beam 1151 and the other end connected to the second main beam 1152. The first mounting bracket 161 is used to mount the backrest mechanism 152. Specifically, the first mounting bracket 161 includes a first mounting member 1611, a second mounting member 1612, a third mounting member 1613, and a first body 1614. The first mounting member 1611, the second mounting member 1612, and the first body 1614 are all disposed on the upper main beam 115. The third mounting member 1613 is disposed on the first body 1614. Specifically, the first main beam 1151 has the first mounting member 1611 and the second mounting member 1612. The second main beam 1152 is also provided with a first mounting member 1611 and a second mounting member 1612. The first main body 1614 is at least partially disposed between the first main beam 1151 and the second main beam 1152. Along the front-rear direction of the all-terrain vehicle 100, the first mounting member 1611 is disposed in front of the second mounting member 1612. The distance between the first mounting member 1611 and the second mounting member 1612 in the front-rear direction is the first distance, and the distance between the first snap-fit ​​member 1524c and the second snap-fit ​​member 1524g in the front-rear direction is the second distance. The first distance and the second distance are basically the same. Through the above arrangement, the first snap-fit ​​member 1524c and the first mounting member 1611 can be snapped together, and the second snap-fit ​​member 1524g and the second mounting member 1612 can be snapped together, thereby making the connection between the mounting bracket 1524 and the frame 11 more convenient, and thus realizing the connection between the backrest mechanism 152 and the frame 11, improving the ease of disassembly and assembly of the backrest mechanism 152.

[0048] In this embodiment, the first locking member 1524c can be a limiting steel wire, and the second locking member 1524g can be a limiting pin. The first mounting member 1611 is provided with a first mounting groove 1611a, which can be configured as an inclined groove. The second mounting member 1612 is provided with a mounting hole 1612a. The first mounting groove 1611a includes a first end and a second end. Along the front-rear and up-down directions of the all-terrain vehicle 100, the first end is open, facing upwards, and located behind the second end. In actual installation, the limiting steel wire can be inserted from the opening at the first end until the limiting steel wire abuts against the second end, i.e., the limiting steel wire can be inserted from the opening of the first mounting groove 1611a into the first mounting groove 1611a. Through the above configuration, the first mounting member 1611 can have a guiding function through the inclined groove 1611a, thereby facilitating the engagement of the limiting steel wire and the first mounting groove 1611a and improving the ease of installation and removal of the limiting steel wire. The second latching member 1524g is inserted into the mounting hole 1612a, thereby achieving the insertion of the second latching member 1524g and the mounting hole 1612a, and through the second latching member 1524g and the mounting hole 1612a, the first mounting bracket 161 limits the backrest mechanism 152. In this embodiment, the first mounting member 1611 can be formed by welding two sheet metal parts together. Through the above arrangement, the contact area between the first mounting member 1611 and the first latching member 1524c can be increased, thereby effectively preventing wear of the first mounting member 1611 and the first latching member 1524c and improving their service life.

[0049] like Figures 7 to 9As shown, in one implementation, the backrest mechanism 152 also includes a locking mechanism 1526. The locking mechanism 1526 is at least partially disposed on and connected to the seat cushion 1522, and at least partially disposed on and connected to the fourth support 1524f. Specifically, the fourth support 1524f has a sixth mounting point 1524m and a seventh mounting point 1524n. The sixth mounting point 1524m is at least partially disposed between the first limiting member 1525b and the second limiting member 1525c, and is used to connect the fourth support 1524f and the locking mechanism 1526. Along the longitudinal direction of the all-terrain vehicle 100, the seventh mounting point 1524n is disposed in front of the fourth support 1524f and located in front of the sixth mounting point 1524m. The seventh mounting point 1524n is used to connect the fourth support 1524f and the locking mechanism 1526. The above configuration allows for a stable connection between the locking mechanism 1526 and the fourth bracket 1524f, thereby improving the stability of the backrest mechanism 152 and ultimately enhancing the safety of the all-terrain vehicle 100. An eighth mounting point 1522a and several ninth mounting points 1522b are provided on the underside of the seat cushion 1522. The eighth mounting point 1522a is located in front of the several ninth mounting points 1522b, and the eighth mounting point 1522a and the several ninth mounting points 1522b are arranged substantially along the same straight line. The eighth mounting point 1522a and the several ninth mounting points 1522b are used to connect the seat cushion 1522 and the locking mechanism 1526. This configuration allows for a stable connection between the locking mechanism 1526 and the seat cushion 1522, thereby improving the stability of the backrest mechanism 152 and ultimately enhancing the safety of the all-terrain vehicle 100.

[0050] In one implementation, a third mounting member 1613 is at least partially disposed between two second mounting members 1612. The third mounting member 1613 is used to connect with the locking mechanism 1526, thereby connecting the mounting bracket 1524 and the first mounting bracket 161. The locking mechanism 1526 includes an unlocking device 1526a, a transmission device 1526b, and a locking device 1526g. The transmission device 1526b is disposed between the unlocking device 1526a and the locking device 1526g, and is used to connect the unlocking device 1526a and the locking device 1526g. The transmission device 1526b is connected to the underside of the seat cushion 1522 via a plurality of ninth mounting points 1522b. The transmission device 1526b is connected to the fourth bracket 1524f via a seventh mounting point 1524n. Specifically, the seventh mounting point 1524n can be welded to the fourth bracket 1524f, and the seventh mounting point 1524n can be a sheet metal part with a first slot. The transmission device 1526b and the seventh mounting point 1524n are engaged through the first slot, facilitating the assembly and disassembly of the transmission device 1526b and improving its assemblability. Several ninth mounting points 1522b can be integrally formed with the seat cushion 1522, and the ninth mounting points 1522b can be plastic parts with a second slot. The transmission device 1526b and the ninth mounting points 1522b are engaged through the second slot. This arrangement facilitates the integrated processing of the ninth mounting points 1522b and the seat cushion 1522, improving processing efficiency, and also facilitates the assembly and disassembly of the transmission device 1526b, improving its assemblability.

[0051] The unlocking device 1526a is connected to the eighth mounting point 1522a. The unlocking device 1526a controls the locking device 1526g via the transmission device 1526b, thereby unlocking or locking the locking device 1526g. The locking device 1526g is connected to the third mounting member 1613. The locking device 1526g connects the mounting bracket 1524 and the first mounting bracket 161, thereby connecting the first mounting bracket 161 and the backrest mechanism 152. Specifically, the locking device 1526g can be a hook, and the third mounting member 1613 can be a retaining ring. The unlocking device 1526a controls the rotation angle of the hook via the transmission device 1526b, thereby locking or unlocking the hook and retaining ring. Through the above settings, the connection between the backrest mechanism 152 and the first mounting bracket 161 can be more stable, and the ease of assembly and disassembly of the backrest mechanism 152 can be improved. In this embodiment, the locking mechanism 1526 includes a first state and a second state. In the first state, the locking device 1526g and the third mounting member 1613 are locked, meaning the first state refers to the locked state of the locking mechanism 1526. In the second state, the locking device 1526g and the third mounting member 1613 are unlocked, meaning the second state refers to the unlocked state of the locking mechanism 1526.

[0052] In one implementation, the transmission device 1526b includes a first connecting portion 1526c, a transmission portion 1526d, a second connecting portion 1526e, and an elastic element 1526f. The first connecting portion 1526c is connected to the unlocking device 1526a. The transmission portion 1526d connects the first connecting portion 1526c and the second connecting portion 1526e. The second connecting portion 1526e connects the transmission portion 1526d and the elastic element 1526f. Specifically, one end of the first connecting portion 1526c is connected to the unlocking device 1526a, the other end of the first connecting portion 1526c is connected to one end of the transmission portion 1526d, the other end of the transmission portion 1526d is connected to one end of the second connecting portion 1526e, the other end of the second connecting portion 1526e is connected to one end of the elastic element 1526f, and the other end of the elastic element 1526f is connected to the locking device 1526g. The elastic element 1526f can be a spring. With the above settings, the unlocking device 1526a can control the locking device 1526g to unlock or lock through the transmission device 1526b, thereby achieving a stable connection between the locking mechanism 1526 and the third mounting member 1613, and further achieving a stable connection between the backrest mechanism 152 and the first mounting bracket 161, and facilitating the disassembly and assembly of the backrest mechanism 152, thus improving the assemblability of the backrest mechanism 152.

[0053] In this embodiment, when the locking mechanism 1526 is in the second state, the user can pull the unlocking device 1526a by hand. The unlocking device 1526a drives the transmission part 1526d through the first connecting part 1526c. The transmission part 1526d pulls the elastic element 1526f through the second connecting part 1526e, thereby causing the elastic element 1526f to pull the locking device 1526g, thus unlocking the locking device 1526g. At this time, the elastic element 1526f is in a stretched state. When the user releases the unlocking device 1526a, the locking mechanism 1526 returns to the first state due to the restoring force of the elastic element 1526f. At this time, the backrest mechanism 152 can be connected to the first mounting bracket 161 or in a disassembled state. When the backrest mechanism 152 is in the disassembled state, the locking mechanism 1526 is also in a locked state, that is, the locking mechanism 1526 is in the first state.

[0054] like Figure 10 and Figure 11As shown, in one implementation, the seat 1522 is provided with an unlocking groove 1522e and a second mounting groove 1522f. The opening of the unlocking groove 1522e is located on the front side of the seat 1522, allowing the user's hand to enter the interior of the seat 1522, thus facilitating the user's control of the unlocking device 1526a. The opening of the second mounting groove 1522f is also located on the front side of the seat 1522, and the saddle 151 is at least partially disposed in the second mounting groove 1522f, thereby reducing the gap between the saddle 151 and the seat 1522, which helps improve the installation stability of the backrest mechanism 152 and allows for a more compact structure for the all-terrain vehicle 100. The unlocking groove 1522e communicates with the second mounting groove 1522f, and the unlocking groove 1522e is located on the upper side of the second mounting groove 1522f.

[0055] like Figure 9 and Figure 10As shown, in this embodiment, the unlocking device 1526a includes an unlocking handle 1526h and a connecting plate 1526j. The unlocking handle 1526h is used to unlock the locking device 1526g, and the connecting plate 1526j is used to connect the unlocking handle 1526h and the transmission device 1526b. The unlocking handle 1526h can be a pull rod or a pull strap, etc. The unlocking handle 1526h includes an unlocking position. When the unlocking handle 1526h is a pull rod, the unlocking handle 1526h and the connecting plate 1526j are integrally formed, the pull rod extends substantially along the left-right direction of the all-terrain vehicle 100, and the pull rod is substantially cylindrical. Along the front-rear direction of the all-terrain vehicle 100, the distance between the axis of the pull rod and the front side of the uppermost end of the unlocking groove 1522e is L. Along the vertical direction of the all-terrain vehicle 100, the distance between the axis of the pull rod and the front side of the uppermost end of the unlocking groove 1522e is H. The position where the axis of the pull rod is located is the unlocking position. In this embodiment, along the front-rear direction of the all-terrain vehicle 100, if the unlocking handle 1526h is at least partially located on the front side of the unlocking groove 1522e, then L is a negative number; if the unlocking handle 1526h is at least partially located on the rear side of the unlocking groove 1522e, then L is a positive number. The value range of L is greater than or equal to -20mm and less than or equal to 150mm. Along the vertical direction of the all-terrain vehicle 100, if the unlocking handle 1526h is at least partially located on the upper side of the unlocking groove 1522e, then H is a negative number; if the unlocking handle 1526h is at least partially located on the lower side of the unlocking groove 1522e, then H is a positive number. The value range of H is greater than or equal to -20mm and less than or equal to 20mm. Specifically, the value range of L is greater than or equal to 10mm and less than or equal to 110mm, and the value range of H is greater than or equal to -15mm and less than or equal to 15mm. In this embodiment, the value of L is greater than or equal to 30 mm and less than or equal to 80 mm, and the value of H is greater than or equal to -10 mm and less than or equal to 10 mm. With the above settings, the locking mechanism 1526 can avoid other parts on the seat cushion 1522, thereby improving the space utilization of the seat cushion 1522 and consequently improving the space utilization of the all-terrain vehicle 100.

[0056] Understandably, when the unlocking handle 1526h is a pull strap or similar structure, the connection point between the unlocking handle 1526h and the connecting plate 1526j is the connection point. The location of this connection point is the unlocked position. Along the front-rear direction of the all-terrain vehicle 100, the distance between the connection point and the front side of the uppermost end of the unlocking slot 1522e is L'. Along the vertical direction of the all-terrain vehicle 100, the distance between the connection point and the front side of the uppermost end of the unlocking slot 1522e is H'. The values ​​of L' and L are essentially the same, and the values ​​of H' and H are essentially the same. Through this arrangement, the locking mechanism 1526 can avoid other parts on the seat cushion 1522, thereby improving the space utilization of the seat cushion 1522 and consequently improving the space utilization of the all-terrain vehicle 100.

[0057] like Figure 12 As shown, in one implementation, the mounting bracket assembly 16 includes a second mounting bracket 162, which is at least partially disposed on and connected to the frame 11. The second mounting bracket 162 is adjustable, allowing adjustment of the assembly tolerances of the all-terrain vehicle 100's components, thereby securing the components and improving the assembly stability of the all-terrain vehicle 100. Specifically, the second mounting bracket 162 can be disposed on the seventh pipe 1133 for securing the fuel assembly 21. The second mounting bracket 162 can also be disposed on the mounting bracket assembly 16 for securing other components of the all-terrain vehicle 100. Through the above arrangement, a stable connection of the all-terrain vehicle 100's components can be achieved. The second mounting bracket 162 includes an adjusting member 1621 and a second body 1622. The adjusting member 1621 is at least partially disposed on the second body 1622 for adjusting the assembly tolerances of the all-terrain vehicle 100's components. The second body 1622 is at least partially disposed on the frame 11 for connecting the frame 11 and the second mounting bracket 162. Specifically, the second body 1622 includes a first mounting portion 1622a, a first fixing portion 1622b, and an adjusting portion 1622d. The adjusting portion 1622d is disposed on the first mounting portion 1622a, and the adjusting portion 1622d and the first mounting portion 1622a are integrally formed. The first fixing portion 1622b can be welded to one end of the first mounting portion 1622a. In this embodiment, the adjusting portion 1622d can be configured as a mounting groove, and the adjusting member 1621 is disposed in the mounting groove, so that the adjusting member 1621 can slide in the adjusting portion 1622d, which facilitates the adjustment of the assembly tolerances of the all-terrain vehicle 100's components. The first mounting portion 1622a is used to connect the frame 11 and the second body 1622, and the first fixing portion 1622b is used to fix the components of the all-terrain vehicle 100. Specifically, one end of the first mounting portion 1622a is connected to the first fixing portion 1622b, and the other end of the first mounting portion 1622a is connected to the frame 11. The adjusting part 1622d is used to set the adjusting member 1621, and the adjusting part 1622d and the adjusting member 1621 are slidably connected, that is, the adjusting member 1621 can slide in the adjusting part 1622d. With the above configuration, when installing the components of the all-terrain vehicle 100, the position of the adjusting member 1621 can be adjusted in real time according to the installation status of the components, thereby achieving stable installation of the components and improving the assemblability of the all-terrain vehicle 100.

[0058] In one implementation, the adjusting member 1621 includes a second mounting portion 1621a and a second fixing portion 1621b. The second mounting portion 1621a is at least partially disposed on the adjusting portion 1622d, and the second mounting portion 1621a and the adjusting portion 1622d are slidably connected, meaning that the second mounting portion 1621a can slide within the adjusting portion 1622d. The second fixing portion 1621b is substantially parallel to the first fixing portion 1622b, thereby facilitating the fixing of components of the all-terrain vehicle 100. Specifically, the first fixing portion 1622b is provided with a first mounting hole 1622c, and the second fixing portion 1621b is provided with a second mounting hole 1621c, wherein the cross-sectional area of ​​the first mounting hole 1622c is larger than the cross-sectional area of ​​the second mounting hole 1621c. In this embodiment, the cross-section of the second mounting hole 1621c is substantially circular. The second mounting bracket 162 includes a first projection plane 1623 perpendicular to the axis of the second mounting hole 1621c. Along the axial direction of the second mounting hole 1621c, the projection of the first mounting hole 1622c onto the first projection plane 1623 is the first projection surface, and the projection of the second mounting hole 1621c onto the first projection plane 1623 is the second projection surface. The area of ​​the first projection surface is larger than the area of ​​the second projection surface, and the second projection surface is located within the first projection surface, that is, the first projection surface completely covers the second projection surface. Through this arrangement, when there are assembly errors in the components of the all-terrain vehicle 100, the relative positions of the second mounting part 1621a and the first mounting part 1622a can be adjusted in real time, allowing the components of the all-terrain vehicle 100 to be better installed through the second mounting hole 1621c, thereby improving the assemblability of the all-terrain vehicle 100's components.

[0059] In this embodiment, the first mounting hole 1622c can be a through hole, provided that the cross-sectional area of ​​the first mounting hole 1622c is greater than the cross-sectional area of ​​the second mounting hole 1621c. The second mounting hole 1621c can be a threaded hole, which facilitates the fixing of the all-terrain vehicle 100 components by bolts or the like; the second mounting hole 1621c can also be a through hole, which facilitates the fixing of the all-terrain vehicle 100 components by interference fit or the like.

[0060] When the second mounting hole 1621c is a threaded hole, a first nut is provided on the lower surface of the second fixing part 1621b. The first nut and the lower surface of the second fixing part 1621b can be fixed by welding or other methods. The second mounting hole 1621c passes through the second fixing part 1621b and the first nut, thereby facilitating the fixing of the all-terrain vehicle 100 components by bolts or other means. The lower surface of the second fixing part 1621b refers to the surface of the second fixing part 1621b away from the first mounting hole 1622c.

[0061] In one implementation, the second mounting portion 1621a and the second fixing portion 1621b are integrally formed. The second fixing portion 1621b has a second mounting portion 1621a at both ends. The adjusting portion 1622d includes a first mounting groove and a second mounting groove. The first mounting groove and the second mounting groove are arranged substantially parallel to each other. At least partially, the second mounting portion 1621a at one end of the second fixing portion 1621b is disposed in the first mounting groove. At least partially, the second mounting portion 1621a at the other end of the second fixing portion 1621b is disposed in the second mounting groove.

[0062] Specifically, the first mounting part 1622a includes a first side plate 1622e, a second side plate 1622f, and a first main board 1622g. One side of the first side plate 1622e is connected to one side of the first main board 1622g, and the first side plate 1622e and the first main board 1622g are arranged substantially perpendicularly. One side of the second side plate 1622f is connected to the other side of the first main board 1622g, and the second side plate 1622f and the first main board 1622g are arranged substantially perpendicularly. An adjustment part 1622d is provided on the first side plate 1622e and the second side plate 1622f, that is, a first mounting groove is provided on the first side plate 1622e, and a second mounting groove is provided on the second side plate 1622f. The first mounting plate and the first side plate 1622e are arranged substantially perpendicularly, and the second mounting plate and the second side plate 1622f are arranged substantially perpendicularly. With the above settings, the first mounting plate can slide better in the first mounting groove, and the second mounting plate can slide better in the second mounting groove, thereby facilitating the adjustment of the assembly tolerance of the all-terrain vehicle 100 parts and improving the assemblability of the all-terrain vehicle 100.

[0063] In this embodiment, weight-reduction holes are provided on the first side plate 1622e, the second side plate 1622f, and the first main plate 1622g to facilitate the weight reduction of the second mounting bracket 162, thereby facilitating the weight reduction of the all-terrain vehicle 100. Furthermore, the first main plate 1622g is provided with several mounting points for connecting the first main plate 1622g and the vehicle frame 11, thus making the connection between the second mounting bracket 162 and the vehicle frame 11 more stable.

[0064] like Figure 13 and Figure 14As shown, in one implementation, the mounting bracket assembly 16 further includes a third mounting bracket 163. The third mounting bracket 163 is at least partially disposed on the frame 11, used to fix components of the all-terrain vehicle 100 and restrict the rotation or movement of these components, thereby achieving the fixing and positioning of the components of the all-terrain vehicle 100. Specifically, the third mounting bracket 163 includes a third mounting portion 1631 and a first limiting portion 1632. The first limiting portion 1632 is at least partially disposed on the third mounting portion 1631, and the third mounting portion 1631 is at least partially disposed on and connected to the frame 11. The third mounting portion 1631 and the first limiting portion 1632 can be integrally molded; the first limiting portion 1632 can also be connected to the third mounting portion 1631 by welding, threaded connection, or other methods, thereby achieving a stable connection between the first limiting portion 1632 and the third mounting portion 1631. In this embodiment, the third mounting bracket 163 can be molded independently, meaning it can be a separate part used to connect the components of the all-terrain vehicle 100 to the frame 11. The third mounting bracket 163 can also be connected to other mounting bracket assemblies 16 to connect these assemblies to the components of the all-terrain vehicle 100. In this case, the third mounting bracket 163 and other mounting bracket assemblies 16 can be integrally molded or connected by welding, bolting, or other methods. When the third mounting bracket 163 is molded independently, it is mounted on and connected to the frame 11. When the third mounting bracket 163 is connected to other mounting bracket assemblies 16, it is at least partially mounted on the other mounting bracket assemblies 16, and the third mounting bracket 163 is connected to the frame 11 through these other mounting bracket assemblies 16.

[0065] Understandably, the third mounting part 1631 is provided with a third mounting hole 1633, which is used to connect the components of the all-terrain vehicle 100. This allows the third mounting hole 1633 and the first limiting part 1632 to simultaneously fix the components of the all-terrain vehicle 100, thereby improving the installation stability of the all-terrain vehicle 100. The third mounting hole 1633 can also serve as a connection point between the frame 11 and the third mounting bracket 163, thereby integrating the mounting points of other components of the all-terrain vehicle 100 and the mounting points of the frame 11. In other words, multiple mounting points are integrated on the third mounting bracket 163, which simplifies the structure of the third mounting bracket 163, makes the structure of the third mounting bracket 163 more compact, and improves the structural compactness of the mounting bracket assembly 16.

[0066] In one implementation, at least some of the components of the all-terrain vehicle 100 form surface contact and / or line contact with the first limiting part 1632. This arrangement makes the limiting effect of the first limiting part 1632 on the components of the all-terrain vehicle 100 more stable, thereby restricting the rotation or movement of the components, reducing wear on the components, and increasing their service life. Furthermore, this arrangement also improves the assemblability of the components, facilitating their installation and disassembly.

[0067] In one implementation, when the third mounting bracket 163 is a separate part, it includes a fourth mounting portion 1634 and a second limiting portion 1635. The second limiting portion 1635 is at least partially disposed on the fourth mounting portion 1634, and can be integrally formed with the fourth mounting portion 1634, or connected to it by welding or bolting. The second limiting portion 1635 can be a first protrusion, which includes at least a first flat surface. The components of the all-terrain vehicle 100 include at least a second flat surface. The first and second flat surfaces abut against each other, causing at least a portion of the components of the all-terrain vehicle 100 to form surface contact with the first limiting portion 1632, thereby facilitating the limiting of the components of the all-terrain vehicle 100 by the second limiting portion 1635. Specifically, the fourth mounting part 1634 is also provided with a fourth mounting hole 1636, which is used to connect the components of the all-terrain vehicle 100. This allows the fourth mounting hole 1636 and the second limiting part 1635 to simultaneously fix the components of the all-terrain vehicle 100, thereby improving the installation stability of the all-terrain vehicle 100. In this embodiment, the fourth mounting hole 1636 can also be used to connect the fourth mounting part 1634 and the frame 11. That is, the fourth mounting hole 1636 can serve as both a mounting hole for the components of the all-terrain vehicle 100 and a connecting hole for the frame 11, achieving the integration of multiple mounting points and thus realizing a stable connection between the third mounting bracket 163 and the frame 11. Furthermore, by integrating the mounting points, the volume of the third mounting bracket 163 is saved, thereby improving the structural compactness of the third mounting bracket 163 and consequently improving the structural compactness of the all-terrain vehicle 100.

[0068] In this embodiment, the fourth mounting portion 1634 includes a first plate and a second plate. The first plate and the second plate are arranged substantially perpendicularly and integrally formed, thereby enabling the fourth mounting portion 1634 to connect better with the frame 11 and improving the stability of the fourth mounting portion 1634. Specifically, the fourth mounting hole 1636 and the second limiting portion 1635 are provided on the first plate.

[0069] In one implementation, the braking assembly 17 includes a three-way mechanism 171 and a brake conduit (not shown). The brake conduit is filled with brake fluid. The three-way mechanism 171 connects the brake conduits, serves to connect several brake conduits, and distributes the brake fluid within the brake conduits. When the third mounting bracket 163 is a separate part, the component mounted on the third mounting bracket 163 can be the three-way mechanism 171. The three-way mechanism 171 and the third mounting bracket 163 are connected through a fourth mounting hole 1636, and the three-way mechanism 171 and the third mounting bracket 163 abut against each other through a second limiting part 1635, thereby fixing and limiting the three-way mechanism 171.

[0070] Understandably, the second limiting part 1635 can also be a first protrusion. A first limiting hole is provided on the component of the all-terrain vehicle 100. The first limiting hole is fitted onto the first protrusion, so that at least part of the component of the all-terrain vehicle 100 forms surface contact with the first limiting part 1632, thereby facilitating the second limiting part 1635 to limit the component of the all-terrain vehicle 100. Specifically, the contour of the outer surface of the first protrusion is substantially consistent with the contour of the inner surface of the first limiting hole, so that the outer surface of the first protrusion and the inner surface of the first limiting hole are substantially fitted together, thereby forming surface contact between the first limiting hole and the first limiting part 1632. In this embodiment, the first protrusion can be a cylinder, and the first limiting hole is fitted onto the cylinder, thereby forming surface contact between the first limiting hole and the cylinder. The inner surface of the first limiting hole refers to the inner wall of the first limiting hole; the shape of the first protrusion can also be a cuboid, a cone, etc., as long as the outline of the outer surface of the first protrusion is basically consistent with the outline of the inner surface of the first limiting hole.

[0071] In one implementation, when the third mounting bracket 163 is connected to other mounting bracket assemblies 16, the third mounting bracket 163 includes a fifth mounting portion 1637 and a third limiting portion 1638. The third limiting portion 1638 is at least partially disposed on the fifth mounting portion 1637, and the third limiting portion 1638 can be integrally formed with the fifth mounting portion 1637, or it can be connected to the fifth mounting portion 1637 by welding or bolting. The third limiting portion 1638 can be a second protrusion, thereby facilitating the limiting of the all-terrain vehicle 100's components by the third limiting portion 1638. Specifically, the fifth mounting portion 1637 is also provided with a fifth mounting hole 1639, which is used to connect the all-terrain vehicle 100's components, so that the fifth mounting hole 1639 and the third limiting portion 1638 simultaneously fix the all-terrain vehicle 100's components, thereby improving the installation stability of the all-terrain vehicle 100. In this embodiment, the fifth mounting hole 1639 can also be used to connect the fifth mounting hole 1639 and the frame 11. That is, the fifth mounting hole 1639 can be used as a mounting hole for the components of the all-terrain vehicle 100 and as a connecting hole for connecting the frame 11, thereby realizing the integration of multiple mounting points.

[0072] In this embodiment, the electrical component 18 is provided with a sixth mounting hole 181 and a second limiting hole 182. The sixth mounting hole 181 and the fifth mounting hole 1639 can be connected by bolts, welding, or other means to connect the electrical component 18 and the third mounting bracket 163. Specifically, the second limiting hole 182 is fitted onto the third limiting part 1638, that is, the second limiting hole 182 is fitted onto the second protrusion, thereby fixing the second limiting hole 182 and the third limiting part 1638, and thus fixing and limiting the electrical component 18 with the third limiting part 1638. Specifically, the second protrusion can be hemispherical, the cross-section of the second limiting hole 182 is basically circular, and the diameter of the cross-section of the second limiting hole 182 is basically the same as the diameter of the second protrusion, so that the second limiting hole 182 and the second protrusion form a line contact, making the fitting of the second protrusion and the second limiting hole 182 more stable. In this embodiment, the second protrusion can also be of other shapes, as long as the second protrusion and the second limiting hole 182 form a line contact.

[0073] Understandably, the third limiting part 1638 can also be a second protrusion. The second protrusion includes at least a third plane, and the all-terrain vehicle 100 component includes at least an edge. The third plane of the second protrusion abuts against the edge of the all-terrain vehicle 100 component, so that the all-terrain vehicle 100 component at least partially forms line contact with the third limiting part 1638, thereby facilitating the second limiting part 1635 to limit the all-terrain vehicle 100 component. Specifically, the edge of the all-terrain vehicle 100 component can be one side of the all-terrain vehicle 100 component. The connection between the third plane and the fifth mounting part 1637 is the first abutment position. The edge of the all-terrain vehicle 100 component abuts against the first abutment position, thereby causing the edge of the all-terrain vehicle 100 component to abut against the third plane of the second protrusion, so that the edge of the all-terrain vehicle 100 component and the third limiting part 1638 form line contact.

[0074] like Figure 15 and Figure 16 As shown, in one implementation, the mounting bracket assembly 16 further includes a sixth mounting bracket 169. The sixth mounting bracket 169 is at least partially mounted on the frame 11, and the transmission assembly 26 is at least partially mounted on the frame 11 via the sixth mounting bracket 169. Specifically, the sixth mounting bracket 169 includes a rear axle bracket 1691 and a power supply bracket 1692. The rear axle bracket 1691 is at least partially mounted on the frame 11 and is used to secure at least a portion of the transmission assembly 26. The power supply bracket 1692 is at least partially mounted on the frame 11 and is used to secure a power socket. The power socket is at least partially mounted on the power supply bracket 1692 and is used to provide an output interface for the trailer power supply.

[0075] In this embodiment, the rear axle bracket 1691 is at least partially disposed on the fourth pillar 114, and the power bracket 1692 is also at least partially disposed on the fourth pillar 114. Along the longitudinal direction of the all-terrain vehicle 100, the rear axle bracket 1691 is disposed on the front side of the fourth pillar 114, and the power bracket 1692 is disposed on the rear side of the fourth pillar 114. Specifically, the ninth pipe fitting 1141 and the tenth pipe fitting 1142 are both provided with a first connecting hole 1143. The first connecting hole 1143 extends substantially along the longitudinal direction of the all-terrain vehicle 100. A bushing is disposed in the first connecting hole 1143 to improve its abrasion resistance and service life. The rear axle bracket 1691 is provided with a second connecting hole 1691a, and the power bracket 1692 is provided with a third connecting hole 1692a. The second connecting hole 1691a connects to the first connecting hole 1143, and the third connecting hole 1692a connects to the first connecting hole 1143, thereby stably connecting the rear axle bracket 1691 and the fourth support column 114, and stably connecting the power supply bracket 1692 and the fourth support column 114. The positions of the first connecting hole 1143, the second connecting hole 1691a, and the third connecting hole 1692a are basically consistent; that is, the centers of the first connecting hole 1143, the second connecting hole 1691a, and the third connecting hole 1692a are basically on the same straight line. This allows the first connecting hole 1143, the second connecting hole 1691a, and the third connecting hole 1692a to be fixed using the same connector, integrating the mounting points of the rear axle bracket 1691 and the power supply bracket 1692 together. This improves the assemblability of the all-terrain vehicle 100, reduces the number of parts in the all-terrain vehicle 100, and ultimately achieves weight reduction in the all-terrain vehicle 100. In this embodiment, the first connecting hole 1143, the second connecting hole 1691a, and the third connecting hole 1692a can be fixed by the same bolt. The fixing method for the first connecting hole 1143, the second connecting hole 1691a, and the third connecting hole 1692a is as follows: the bolt passes through the third connecting hole 1692a, the first connecting hole 1143, and the second connecting hole 1691a in sequence, and is then fixed by a nut, thereby achieving a stable connection between the fourth support 114, the rear axle bracket 1691, and the power supply bracket 1692.

[0076] Understandably, the bolts can also pass through the second connecting hole 1691a, the first connecting hole 1143, and the third connecting hole 1692a in sequence, and then be fixed by nuts, thereby achieving a stable connection between the fourth support 114, the rear axle bracket 1691, and the power supply bracket 1692.

[0077] In one implementation, the power bracket 1692 includes a first mounting portion 1692b, a connecting portion 1692c, and a second mounting portion 1692d. The first mounting portion 1692b and the second mounting portion 1692d are connected by the connecting portion 1692c. Specifically, along the vertical direction of the all-terrain vehicle 100, the first mounting portion 1692b is positioned above the second mounting portion 1692d. The first mounting portion 1692b and the second mounting portion 1692d extend substantially along the vertical direction of the all-terrain vehicle 100, and the connecting portion 1692c extends substantially along the front-rear direction of the all-terrain vehicle 100. The lower end of the first mounting portion 1692b is connected to the front end of the connecting portion 1692c, and the upper end of the second mounting portion 1692d is connected to the rear end of the connecting portion 1692c. The first mounting portion 1692b, the connecting portion 1692c, and the second mounting portion 1692d are integrally formed. In this embodiment, the first mounting portion 1692b is provided with a third connecting hole 1692a, and the second mounting portion 1692d is provided with a fourth connecting hole 1692e and a weight-reduction hole 1692f. The weight-reduction hole 1692f is located at the center of the second mounting portion 1692d, and the fourth connecting hole 1692e is arranged around the weight-reduction hole 1692f. The weight-reduction hole 1692f is used to reduce the weight of the second mounting portion 1692d, thereby achieving weight reduction of the all-terrain vehicle 100. The fourth connecting hole 1692e is used to connect a power socket.
