Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicles, in particular to an all-terrain vehicle. BACKGROUND

[0002] An all-terrain vehicle refers to a vehicle that can travel on any terrain and walk freely on terrain where ordinary vehicles are difficult to maneuver. The vehicle model of the all-terrain vehicle has multiple purposes and is not limited by road conditions, so the structural stability and strength of the all-terrain vehicle are required to be higher.

[0003] At present, the all-terrain vehicle is generally provided with a saddle for a driver to sit on and a seat for a passenger to sit on. In the prior art, the backrest of the seat is a rigid structure and cannot provide elastic buffering, so the impact force of the backrest on the human body is large when the vehicle is driven violently and bumpy, thereby reducing the comfort of the seat. SUMMARY

[0004] In order to solve the problems of the prior art, the purpose of the present application is to provide an all-terrain vehicle which can make the backrest mechanism have a buffering effect.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:

[0006] An all-terrain vehicle comprises a vehicle frame, a walking assembly, a suspension assembly, a power assembly, and a saddle assembly. The walking assembly is at least partially arranged on the vehicle frame and comprises a first walking wheel and a second walking wheel. The suspension assembly comprises a front suspension and a rear suspension. The first walking wheel is connected to the vehicle frame through the front suspension, and the second walking wheel is connected to the vehicle frame through the rear suspension. The power assembly is at least partially arranged on the vehicle frame. The saddle assembly is at least partially arranged on the vehicle frame and comprises a backrest mechanism. The backrest mechanism comprises a mounting bracket, a skeleton, and a buffering mechanism. The mounting bracket and the skeleton are connected through the buffering mechanism. The buffering mechanism comprises a limiting piece, a buffering piece, and a buffering rod. The limiting piece is used to connect the mounting bracket and the skeleton. The buffering piece is arranged on the mounting bracket and has elasticity. The buffering rod is arranged on the limiting piece and is at least partially arranged on the front side of the buffering piece. The buffering rod comprises a first position and a second position relative to the buffering piece, wherein the first position is in abutment with each other, and the second position is in contact with each other. The skeleton is rotationally connected to the mounting bracket through the limiting piece. The skeleton rotates relative to the mounting bracket between a first angle and a second angle. When the skeleton is at the first angle relative to the mounting bracket, the buffering rod is at the second position relative to the buffering piece. When the skeleton is at the second angle relative to the mounting bracket, the buffering rod is at the first position relative to the buffering piece.

[0007] Further, the first angle and the second angle form a rotation angle, and the rotation angle is greater than or equal to 0° and less than or equal to 60°.

[0008] Further, the rotation angle is greater than or equal to 0° and less than or equal to 15°.

[0009] Further, the rotation angle is greater than or equal to 0° and less than or equal to 10°.

[0010] Further, the buffering mechanism further comprises a connecting piece, the connecting piece being used for connecting the framework and the limiting piece, the limiting piece being provided with a limiting slot, and the connecting piece being provided with a limiting sheet, the limiting sheet being at least partially arranged in the limiting slot.

[0011] Further, the limiting slot comprises a first limit position and a second limit position, when the limiting sheet and the first limit position abut, the framework is at a first angle relative to the mounting support, and when the limiting sheet and the second limit position abut, the framework is at a second angle relative to the mounting support.

[0012] Further, along the front-rear direction of the all-terrain vehicle, the first limit position is located at the rear side of the second limit position.

[0013] Further, when the buffering rod is at the first position relative to the buffering piece, the buffering piece exerts a first force on the buffering rod, and when the buffering rod is at the second position relative to the buffering piece, the buffering piece exerts a second force on the buffering rod, the first force being greater than the second force.

[0014] Further, the buffering piece comprises an integrated mounting portion and a connecting portion, the mounting portion being arranged on the mounting support, and the connecting portion being arranged at the front side of the buffering rod and abutting the buffering rod.

[0015] Further, the connecting piece is provided with a containing slot, and the framework is at least partially arranged in the containing slot.

[0016] Compared with the prior art, the all-terrain vehicle provided by the present application can provide elastic buffering through the buffering piece when the backrest mechanism is driving, reduce the impact force of the backrest mechanism on the passenger, and thus improve the comfort and safety of the all-terrain vehicle.

The fourth connecting piece 1525g is used to connect the second limiting piece 1525c and the second framework 1523c, and the fourth connecting piece 1525g and the second limiting piece 1525c are rotationally connected. Specifically, one end of the third connecting piece 1525e is provided with a first accommodating groove 1525f, one end of the first framework 1523b is at least partially arranged in the first accommodating groove 1525f, and the first framework 1523b and the first accommodating groove 1525f are connected; one end of the fourth connecting piece 1525g is provided with a second accommodating groove 1525h, one end of the second framework 1523c is at least partially arranged in the second accommodating groove 1525h, and the second framework 1523c and the second accommodating groove 1525h are connected.

[0043] In the embodiment, the first limiting piece 1525b is provided with a limiting slot 1525d, and the other end of the third connecting piece 1525e is provided with a limiting piece 1525j; the second limiting piece 1525c is provided with a limiting slot 1525d, and the other end of the fourth connecting piece 1525g is provided with a limiting piece 1525j. The limiting piece 1525j is at least partially arranged in the limiting slot 1525d, the limiting slot 1525d is used for limiting the movement range of the limiting piece 1525j, thereby controlling the rotation range of the third connecting piece 1525e relative to the first limiting piece 1525b, and controlling the rotation range of the fourth connecting piece 1525g relative to the second limiting piece 1525c, and further controlling the rotation range of the backrest 1521 and the framework 1523. The limiting slot 1525d includes a first limit position and a second limit position. In the front-rear direction of the all-terrain vehicle 100, the first limit position is at least partially located on the rear side of the second limit position. When the limiting piece 1525j and the first limit position abut, the framework 1523 is at a first angle relative to the mounting bracket 1524; when the limiting piece 1525j and the second limit position abut, the framework 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 framework 1523 rotates between the first angle and the second angle relative to the mounting bracket 1524. Through the above arrangement, the rotation angle α of the backrest 1521 and the framework 1523 can be limited within a certain rotation range, thereby meeting the buffering rotation of the backrest 1521 and the framework 1523 while improving the safety of the backrest 1521 and the framework 1523. Specifically, the rotation angle α is greater than or equal to 0° and less than or equal to 60°. In the 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 buffering mechanism 1525 further includes a buffering rod 1525r. The buffering rod 1525r is at least partially arranged between the third connecting piece 1525e and the fourth connecting piece 1525g, and one end of the buffering rod 1525r is connected to the third connecting piece 1525e, and the other end of the buffering rod 1525r is connected to the fourth connecting piece 1525g. In the embodiment, one end of the buffering rod 1525r is welded to the third connecting piece 1525e, and the other end of the buffering rod 1525r is welded to the fourth connecting piece 1525g. The buffering piece 1525n includes an integrated mounting portion and a connecting portion. The mounting portion is used for connecting the buffering piece 1525n and the fourth bracket 1524f, and the connecting portion abuts or contacts the buffering rod 1525r. In the embodiment, the connecting portion has elasticity, so that under the action of the buffering rod 1525r, the connecting portion can rotate relative to the mounting portion. In the front-rear direction of the all-terrain vehicle 100, the buffering rod 1525r is arranged on the front side of the connecting portion, facilitating the rotation of the connecting portion relative to the mounting portion under the action of the buffering rod 1525r.

[0045] In the embodiment, the buffer rod 1525r relative to the buffer 1525n includes a first position of mutual abutment and a second position of mutual contact. When the buffer rod 1525r relative to the buffer 1525n is in the first position, the force of the buffer 1525n on the buffer rod 1525r is a first force; when the buffer rod 1525r relative to the buffer 1525n is in the second position, the force of the buffer 1525n on the buffer rod 1525r is a second force. The first force is greater than the second force. Wherein, when the framework 1523 relative to the mounting bracket 1524 is in the first angle, the buffer rod 1525r relative to the buffer 1525n is in the second position of mutual contact; when the framework 1523 relative to the mounting bracket 1524 is in the second angle, the buffer rod 1525r relative to the buffer 1525n is in the first position of mutual abutment. Through the above setting, the abutment 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 1525n, so as to change the angle of the framework 1523 relative to the mounting bracket 1524, and further limit the rotation angle α of the backrest 1521 and the framework 1523 within a certain rotation range.

[0046] As an implementation manner, one end of the third bracket 1524e is provided with a first clamping piece 1524c, and the other end of the third bracket 1524e is also provided with a first clamping piece 1524c. One end of the fourth bracket 1524f is provided with a second clamping piece 1524g, and the other end of the fourth bracket 1524f is also provided with a second clamping piece 1524g. Specifically, the first clamping piece 1524c is arranged on the lower side of the third bracket 1524e, and the second clamping piece 1524g is arranged on the lower side of the fourth bracket 1524f. The first clamping piece 1524c is arranged on the front side of the second clamping piece 1524g.

[0047] As Figure 6As shown, the mounting rack assembly 16 comprises a first mounting rack 161 extending substantially along the left-right direction. The first mounting rack 161 is disposed at least partially between the first main beam 1151 and the second main beam 1152, one end of the first mounting rack 161 is connected to the first main beam 1151, and the other end of the first mounting rack 161 is connected to the second main beam 1152. The first mounting rack 161 is used to mount the backrest mechanism 152. Specifically, the first mounting rack 161 comprises a first mounting piece 1611, a second mounting piece 1612, a third mounting piece 1613, and a first main body 1614. The first mounting piece 1611, the second mounting piece 1612, and the first main body 1614 are all disposed on the upper main beam 115. The third mounting piece 1613 is disposed on the first main body 1614. Specifically, the first mounting piece 1611 and the second mounting piece 1612 are disposed on the first main beam 1151. The first mounting piece 1611 and the second mounting piece 1612 are also disposed on the second main beam 1152. The first main body 1614 is disposed at least partially between the first main beam 1151 and the second main beam 1152. In the front-rear direction of the ATV 100, the first mounting piece 1611 is disposed on the front side of the second mounting piece 1612. The distance between the first mounting piece 1611 and the second mounting piece 1612 in the front-rear direction is a first distance, and the distance between the first clamping piece 1524c and the second clamping piece 1524g in the front-rear direction is a second distance. The first distance and the second distance are substantially the same. Through the above arrangement, the first clamping piece 1524c and the first mounting piece 1611 can be clamped, and the second clamping piece 1524g and the second mounting piece 1612 can be clamped, thereby making the connection of the mounting bracket 1524 and the frame 11 more convenient, and further realizing the connection of the backrest mechanism 152 and the frame 11, and improving the disassembly and assembly convenience of the backrest mechanism 152.

[0048] In the embodiment, the first clamping member 1524c can be a limiting steel wire, and the second clamping member 1524g can be a limiting pin. The first mounting member 1611 is provided with a first mounting slot 1611a, and the first mounting slot 1611a can be an inclined slot. The second mounting member 1612 is provided with a mounting hole 1612a. The first mounting slot 1611a includes a first end and a second end. In the front-rear and up-down directions of the all-terrain vehicle 100, the first end is an opening, the opening is upwardly arranged, and the first end is located at the rear side of the second end. In actual installation, the limiting steel wire can be clamped from the opening of the first end until the limiting steel wire and the second end abut, that is, the limiting steel wire can be clamped into the first mounting slot 1611a from the opening of the first mounting slot 1611a. Through the above arrangement, the first mounting member 1611 has a guiding effect through the first mounting slot 1611a arranged as an inclined slot, thereby facilitating the clamping of the limiting steel wire and the first mounting slot 1611a and improving the disassembly and assembly convenience of the limiting steel wire. The second clamping member 1524g is inserted into the mounting hole 1612a, thereby realizing the insertion of the second clamping member 1524g and the mounting hole 1612a, and realizing the limiting of the first mounting bracket 161 to the backrest mechanism 152 through the second clamping member 1524g and the mounting hole 1612a. In the embodiment, the first mounting member 1611 can be two sheet metal members combined and welded. Through the above arrangement, the contact area of the first mounting member 1611 and the first clamping member 1524c can be increased, thereby effectively preventing the wear of the first mounting member 1611 and the first clamping member 1524c and improving the service life of the first mounting member 1611 and the first clamping member 1524c.

[0049] As Figures 7 to 9As shown, as an implementation form, the backrest mechanism 152 further comprises a locking mechanism 1526. The locking mechanism 1526 is at least partially arranged on and connected with the cushion 1522, and is at least partially arranged on and connected with the fourth support 1524f. Specifically, the fourth support 1524f is provided with a sixth mounting point 1524m and a seventh mounting point 1524n. The sixth mounting point 1524m is at least partially arranged between the first limiting piece 1525b and the second limiting piece 1525c, and is used to connect the fourth support 1524f and the locking mechanism 1526. The seventh mounting point 1524n is arranged on the front side of the fourth support 1524f and located on the front side of the sixth mounting point 1524m along the front-rear direction of the all-terrain vehicle 100. The seventh mounting point 1524n is used to connect the fourth support 1524f and the locking mechanism 1526. Through the above arrangement, the locking mechanism 1526 and the fourth support 1524f can be stably connected, thereby improving the stability of the backrest mechanism 152, and further improving the safety of the all-terrain vehicle 100. The lower side of the cushion 1522 is provided with an eighth mounting point 1522a and a plurality of ninth mounting points 1522b. The eighth mounting point 1522a is arranged on the front side of the plurality of ninth mounting points 1522b, and the eighth mounting point 1522a and the plurality of ninth mounting points 1522b are arranged along substantially the same straight line. The eighth mounting point 1522a and the plurality of ninth mounting points 1522b are used to connect the cushion 1522 and the locking mechanism 1526. Through the above arrangement, the locking mechanism 1526 and the cushion 1522 can be stably connected, thereby improving the stability of the backrest mechanism 152, and further improving the safety of the all-terrain vehicle 100.

[0050] As an implementation form, the third mounting member 1613 is arranged at least partially between the two second mounting members 1612, and the third mounting member 1613 is used to connect with the locking mechanism 1526, so as to connect the mounting support 1524 and the first mounting frame 161. The locking mechanism 1526 comprises an unlocking device 1526a, a transmission device 1526b and a locking device 1526g. The transmission device 1526b is arranged 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 lower side of the cushion 1522 through a plurality of ninth mounting points 1522b. The transmission device 1526b is connected to the fourth support 1524f through a seventh mounting point 1524n. Specifically, the seventh mounting point 1524n can be welded with the fourth support 1524f, and the seventh mounting point 1524n can be a sheet metal member provided with a first clamping groove. The transmission device 1526b is clamped with the seventh mounting point 1524n through the first clamping groove, so as to facilitate disassembly and assembly of the transmission device 1526b. The plurality of ninth mounting points 1522b can be integrally formed with the cushion 1522, and the ninth mounting point 1522b can be a plastic member provided with a second clamping groove. The transmission device 1526b is clamped with the ninth mounting point 1522b through the second clamping groove. Through the above arrangement, the integral processing of the ninth mounting point 1522b and the cushion 1522 is facilitated, the processing efficiency is improved, and the disassembly and assembly of the transmission device 1526b are facilitated, and the assembly of the transmission device 1526b is improved.

[0051] The unlocking device 1526a is connected with the eighth mounting point 1522a, and the unlocking device 1526a is used to control the locking device 1526g through the transmission device 1526b, so as to unlock or lock the locking device 1526g. The locking device 1526g is connected with the third mounting member 1613, and the locking device 1526g is used to connect the mounting support 1524 and the first mounting frame 161, so as to connect the first mounting frame 161 and the backrest mechanism 152. Specifically, the locking device 1526g can be a hook, the third mounting member 1613 can be a clasp, and the unlocking device 1526a controls the rotation angle of the hook through the transmission device 1526b, so as to realize the locking or unlocking of the hook and the clasp. Through the above arrangement, the connection between the backrest mechanism 152 and the first mounting frame 161 is more stable, and the disassembly and assembly convenience of the backrest mechanism 152 is improved. In the embodiment, the locking mechanism 1526 comprises a first state and a second state. In the first state, the locking device 1526g and the third mounting member 1613 are locked, i.e. 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, i.e. 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 the embodiment, the unlocking device 1526a comprises 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, a pull belt or the like. The unlocking handle 1526h comprises 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 ATV 100, and the pull rod is substantially a cylinder. In the front-rear direction of the ATV 100, the distance between the axis of the pull rod and the front side of the uppermost end of the unlocking slot 1522e is L. In the up-down direction of the ATV 100, the distance between the axis of the pull rod and the front side of the uppermost end of the unlocking slot 1522e is H. The position of the axis of the pull rod is the unlocking position. In the embodiment, in the front-rear direction of the ATV 100, if the unlocking handle 1526h is at least partially located on the front side of the unlocking slot 1522e, L is negative; if the unlocking handle 1526h is at least partially located on the rear side of the unlocking slot 1522e, L is positive. The value range of L is greater than or equal to -20 mm and less than or equal to 150 mm. In the up-down direction of the ATV 100, if the unlocking handle 1526h is at least partially located on the upper side of the unlocking slot 1522e, H is negative; if the unlocking handle 1526h is at least partially located on the lower side of the unlocking slot 1522e, H is positive. The value range of H is greater than or equal to -20 mm and less than or equal to 20 mm. Specifically, the value range of L is greater than or equal to 10 mm and less than or equal to 110 mm, and the value range of H is greater than or equal to -15 mm and less than or equal to 15 mm. In the embodiment, the value range of L is greater than or equal to 30 mm and less than or equal to 80 mm, and the value range of H is greater than or equal to -10 mm and less than or equal to 10 mm. Through the above setting, the locking mechanism 1526 can avoid other parts on the seat cushion 1522, thereby improving the space utilization of the seat cushion 1522 and the ATV 100.

[0056] It can be understood that when the unlocking handle 1526h is a pull belt or the like, the connection between the unlocking handle 1526h and the connecting plate 1526j is a connection point. The position of the connection point is the unlocking position. In the front-rear direction of the ATV 100, the distance between the connection point and the front side of the uppermost end of the unlocking slot 1522e is L'. In the up-down direction of the ATV 100, the distance between the connection point and the front side of the uppermost end of the unlocking slot 1522e is H'. The value range of L' is basically the same as that of L, and the value range of H' is basically the same as that of H. Through the above setting, the locking mechanism 1526 can avoid other parts on the seat cushion 1522, thereby improving the space utilization of the seat cushion 1522 and the ATV 100.

[0057] As shown in Figure 12 As an implementation, the mounting rack assembly 16 includes a second mounting rack 162, which is arranged on and connected with the vehicle frame 11. The second mounting rack 162 is adjustable, and can adjust the assembly tolerance of the parts of the all-terrain vehicle 100, thereby fixing the parts of the all-terrain vehicle 100 and improving the assembly stability of the all-terrain vehicle 100. Specifically, the second mounting rack 162 can be arranged on the seventh pipe 1133 and used to fix the fuel assembly 21. The second mounting rack 162 can also be arranged on the mounting rack assembly 16 and used to fix the remaining parts of the all-terrain vehicle 100. Through the above arrangement, the stable connection of the parts of the all-terrain vehicle 100 can be achieved. The second mounting rack 162 includes an adjusting piece 1621 and a second main body 1622. The adjusting piece 1621 is arranged on the second main body 1622 and used to adjust the assembly tolerance of the parts of the all-terrain vehicle 100. The second main body 1622 is arranged on the vehicle frame 11 and used to connect the vehicle frame 11 and the second mounting rack 162. Specifically, the second main body 1622 includes a first mounting portion 1622a, a first fixing portion 1622b, and an adjusting portion 1622d. The adjusting portion 1622d is arranged on the first mounting portion 1622a and integrally formed with the first mounting portion 1622a. The first fixing portion 1622b can be welded on one end of the first mounting portion 1622a. In this embodiment, the adjusting portion 1622d can be arranged as a mounting groove, and the adjusting piece 1621 is arranged in the mounting groove, so that the adjusting piece 1621 can slide in the adjusting portion 1622d, thereby facilitating the adjustment of the assembly tolerance of the parts of the all-terrain vehicle 100. The first mounting portion 1622a is used to connect the vehicle frame 11 and the second main body 1622, and the first fixing portion 1622b is used to fix the parts of the all-terrain vehicle 100. Specifically, one end of the first mounting portion 1622a is connected with the first fixing portion 1622b, and the other end of the first mounting portion 1622a is connected with the vehicle frame 11. The adjusting portion 1622d is used to arrange the adjusting piece 1621, and the adjusting portion 1622d and the adjusting piece 1621 are in sliding connection, i.e., the adjusting piece 1621 can slide in the adjusting portion 1622d. Through the above arrangement, when the parts of the all-terrain vehicle 100 are installed, the position of the adjusting piece 1621 can be adjusted in real time according to the installation of the parts, thereby achieving the stable installation of the parts and improving the assembly of the all-terrain vehicle 100.

[0058] As an implementation form, the adjusting member 1621 comprises a second mounting portion 1621a and a second fixing portion 1621b. The second mounting portion 1621a is arranged at least partially on the adjusting portion 1622d, and the second mounting portion 1621a and the adjusting portion 1622d are in sliding connection, that is, the second mounting portion 1621a can slide in the adjusting portion 1622d. The second fixing portion 1621b is arranged substantially parallel to the first fixing portion 1622b, thereby facilitating fixing of the parts 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, and the cross-sectional area of the first mounting hole 1622c is greater than the cross-sectional area of the second mounting hole 1621c. In the embodiment, the cross section of the second mounting hole 1621c is substantially circular. The second mounting bracket 162 comprises a first projection plane 1623 perpendicular to the axis of the second mounting hole 1621c. In the direction of the axis of the second mounting hole 1621c, the projection of the first mounting hole 1622c on the first projection plane 1623 is a first projection face, and the projection of the second mounting hole 1621c on the first projection plane 1623 is a second projection face. The area of the first projection face is greater than the area of the second projection face, and the second projection face is located in the first projection face, that is, the first projection face completely covers the second projection face. Through the above arrangement, when there is an assembly error in the parts of the all-terrain vehicle 100, the relative positions of the second mounting portion 1621a and the first mounting portion 1622a can be adjusted in real time, so that the parts of the all-terrain vehicle 100 can be better installed through the second mounting hole 1621c, thereby improving the assembly of the parts of the all-terrain vehicle 100.

[0059] In the embodiment, the first mounting hole 1622c can be a through hole, and only needs to satisfy 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, facilitating fixing of the parts of the all-terrain vehicle 100 by bolts or the like; or the second mounting hole 1621c can be a through hole, facilitating fixing of the parts of the all-terrain vehicle 100 by interference fit or the like.

[0060] When the second mounting hole 1621c is a threaded hole, the lower surface of the second fixing portion 1621b is provided with a first nut, the lower surface of the second fixing portion 1621b and the first nut can be fixed by welding or the like, and the second mounting hole 1621c penetrates the second fixing portion 1621b and the first nut, thereby facilitating fixing of the parts of the all-terrain vehicle 100 by bolts or the like. The lower surface of the second fixing portion 1621b refers to the surface of the second fixing portion 1621b away from the first mounting hole 1622c.

[0061] As an implementation manner, the second mounting portion 1621a and the second fixing portion 1621b are integrally formed. The second mounting portion 1621a is arranged at both ends of the second fixing portion 1621b. The adjusting portion 1622d includes a first mounting slot and a second mounting slot. The first mounting slot and the second mounting slot are arranged substantially in parallel. The second mounting portion 1621a at one end of the second fixing portion 1621b is arranged at least partially in the first mounting slot. The second mounting portion 1621a at the other end of the second fixing portion 1621b is arranged at least partially in the second mounting slot.

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

[0063] In the embodiment, the first side plate 1622e, the second side plate 1622f, and the first main plate 1622g are all provided with weight-reducing holes, which facilitates the light weight of the second mounting bracket 162, thereby facilitating the light weight of the all-terrain vehicle 100. In addition, the first main plate 1622g is also provided with a plurality of mounting points, which are used to connect the first main plate 1622g and the vehicle frame 11, thereby making the connection of the second mounting bracket 162 and the vehicle frame 11 more stable.

[0064] As Figure 13 and Figure 14As shown, as an implementation manner, the mounting rack assembly 16 further comprises a third mounting rack 163. The third mounting rack 163 is arranged at least partially on the vehicle frame 11, and is used for fixing parts of the all-terrain vehicle 100 and limiting rotation or movement of the parts of the all-terrain vehicle 100, so as to realize fixing and limiting of the parts of the all-terrain vehicle 100. Specifically, the third mounting rack 163 comprises a third mounting portion 1631 and a first limiting portion 1632. The first limiting portion 1632 is arranged at least partially on the third mounting portion 1631, and the third mounting portion 1631 is arranged at least partially on the vehicle frame 11 and connected with the vehicle frame 11. The third mounting portion 1631 and the first limiting portion 1632 can be an integral molding; the first limiting portion 1632 can also be connected with the third mounting portion 1631 by welding, threaded connection or the like, so as to realize stable connection of the first limiting portion 1632 and the third mounting portion 1631. In the embodiment, the third mounting rack 163 can be formed separately, that is, the third mounting rack 163 can be used as a separate part for connecting the parts of the all-terrain vehicle 100 and the vehicle frame 11. The third mounting rack 163 can also be connected with other mounting rack assemblies 16, and is used for connecting other mounting rack assemblies 16 and the parts of the all-terrain vehicle 100. At this time, the third mounting rack 163 and other mounting rack assemblies 16 can be integrally formed, or can be connected by welding, bolt connection or the like. When the third mounting rack 163 is formed separately, the third mounting rack 163 is arranged on the vehicle frame 11 and connected with the vehicle frame 11.

[0065] It can be understood that the third mounting portion 1631 is provided with a third mounting hole 1633, and the third mounting hole 1633 is used for connecting the parts of the all-terrain vehicle 100, so that the third mounting hole 1633 and the first limiting portion 1632 simultaneously fix the parts of the all-terrain vehicle 100, thereby improving the mounting stability of the all-terrain vehicle 100. The third mounting hole 1633 can also be used as a connecting point of the vehicle frame 11 and the third mounting rack 163, so as to integrate mounting points of other parts of the all-terrain vehicle 100 and mounting points of the vehicle frame 11, that is, multiple mounting points are integrated on the third mounting rack 163, thereby simplifying the structure of the third mounting rack 163, making the structure of the third mounting rack 163 more compact, and improving the compactness of the mounting rack assembly 16.

[0066] As an implementation form, the parts of the all-terrain vehicle 100 are at least partially in surface contact and / or line contact with the first limiting portion 1632. Through the above arrangement, the first limiting portion 1632 can more stably limit the parts of the all-terrain vehicle 100, thereby limiting the rotation or movement of the parts of the all-terrain vehicle 100, further reducing the wear of the parts of the all-terrain vehicle 100, and improving the service life of the parts of the all-terrain vehicle 100. In addition, through the above arrangement, the assembly of the parts of the all-terrain vehicle 100 can be improved, and the installation or disassembly of the parts of the all-terrain vehicle 100 is facilitated.

Specifically, the second protrusion can be a hemispherical shape, 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 and the diameter of the second protrusion are basically the same, so that the second limiting hole 182 and the second protrusion constitute a line contact, and the sleeving of the second protrusion and the second limiting hole 182 is more stable.
