Description

Technical Field

[0001] This invention relates to the field of vehicles, and in particular to an all-terrain vehicle. Background Technology

[0002] When an ATV starts, the power system transmits power to the rear wheel via the transmission system (chain drive, gear drive, belt drive, etc.). While the rear wheel is statically rubbing against the ground, it also transmits power to the rear swingarm. Therefore, the rear swingarm of an ATV needs to withstand a significant power output. When the ATV brakes, the rear swingarm, located between the frame and the rear wheel, bears all the drag force. When the ATV turns, the rear swingarm absorbs longitudinal pulling forces to maintain a comfortable and stable cornering process.

[0003] It is evident that the rear swingarm bears a significant force in an all-terrain vehicle. Consequently, the mounting point on the frame where the rear swingarm is installed must possess high rigidity and strength to support the rear swingarm during all-terrain vehicle operation.

[0004] Currently, the rear swingarm mounting point of all-terrain vehicles is suspended on the outside, resulting in poor rigidity and strength. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an all-terrain vehicle with a rear rocker arm mounting point that has high rigidity and strength.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An all-terrain vehicle includes: a frame; a running gear, at least partially mounted on the frame and including a first wheel and a second wheel; a suspension assembly, including a front suspension and a rear suspension, the first wheel being connected to the frame via the front suspension and the second wheel being connected to the frame via the rear suspension; a power assembly, at least partially mounted on the frame; the frame includes a first strut, the first strut including: a first tube; a second tube disposed below the first tube; a sheet metal part disposed between the first and second tubes; the sheet metal part having mounting holes, through which at least a portion of the rear suspension is connected to the frame; the all-terrain vehicle includes a plane of symmetry perpendicular to the left-right direction, the first tube... The intersection of the front and lower sides is the first straight line; the intersection of the rear and lower sides of the first pipe fitting is the second straight line; the intersection of the front and upper sides of the second pipe fitting is the third straight line; and the intersection of the rear and upper sides of the second pipe fitting is the fourth straight line. Along the left-right direction, the projection of the first straight line onto the plane of symmetry is the first projection point; the projection of the second straight line onto the plane of symmetry is the second projection point; the projection of the third straight line onto the plane of symmetry is the third projection point; and the projection of the fourth straight line onto the plane of symmetry is the fourth projection point. The first, second, third, and fourth projection points form the first projection plane. The projection of the mounting hole onto the plane of symmetry along the left-right direction is the second projection plane. The second projection plane is located within the first projection plane.

[0008] Furthermore, the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface is greater than or equal to 12.5 and less than or equal to 23.4.

[0009] Furthermore, the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface is greater than or equal to 14.3 and less than or equal to 21.6.

[0010] Furthermore, the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface is greater than or equal to 16.1 and less than or equal to 19.8.

[0011] Furthermore, the axis of the mounting hole extends substantially in the left-right direction.

[0012] Furthermore, the upper end of the sheet metal part is provided with a mounting groove, and the upper end of the sheet metal part and the first pipe are connected through the mounting groove.

[0013] Furthermore, the first fitting is at least partially disposed in the mounting groove.

[0014] Furthermore, a connector is provided at the lower end of the sheet metal part, and the sheet metal part and the second pipe are connected through the connector.

[0015] Furthermore, the first pipe fitting extends substantially in the left-right direction, and the second pipe fitting extends substantially in the left-right direction.

[0016] Furthermore, the first support also includes a third pipe fitting and a fourth pipe fitting. The third pipe fitting is located on the upper side of the first pipe fitting and connected to one end of the first pipe fitting; the fourth pipe fitting is located on the upper side of the first pipe fitting and connected to the other end of the first pipe fitting.

[0017] Compared with the prior art, the all-terrain vehicle provided by the present invention can set the mounting point of the rear swing arm between the first pipe and the second pipe, thereby eliminating the bending moment of the second sheet metal part, making the second sheet metal part better under stress, and improving the strength and rigidity of the second sheet metal part.

Specifically, the first support column 111 includes a first pipe component 1111, a second pipe component 1112, and a first sheet metal component 1113.

One end of the third pipe fitting 1121 is connected to the first main beam 1151, and the other end of the third pipe fitting 1121 is connected to the third main beam 1161. One end of the fourth pipe fitting 1122 is connected to the second main beam 1152, and the other end of the fourth pipe fitting 1122 is connected to the third main beam 1161. One end of the fifth pipe fitting 1131 is connected to the first main beam 1151, and the other end of the fifth pipe fitting 1131 is connected to one end of the seventh pipe fitting 1133. One end of the sixth pipe fitting 1132 is connected to the first main beam 1151, and the other end of the sixth pipe fitting 1132 is connected to the other end of the seventh pipe fitting 1133. One end of the eighth pipe fitting 1134 is connected to the third main beam 1161, and the other end of the eighth pipe fitting 1134 is connected to the fourth main beam 1162. The seventh pipe fitting 1133 and the eighth pipe fitting 1134 are connected by the second sheet metal part 1135. One end of the ninth pipe fitting 1141 is connected to the first main beam 1151, and the other end of the ninth pipe fitting 1141 is connected to the third main beam 1161. One end of the tenth pipe fitting 1142 is connected to the second main beam 1152, and the other end of the tenth pipe fitting 1142 is connected to the fourth main beam 1162.

[0032] 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. Along the vertical direction of the all-terrain vehicle 100, the first pipe 1111 and the second pipe 1112 are both located on the upper side of the first sheet metal part 1113, the first main beam 1151 is located on the upper side of the third main beam 1161, the second main beam 1152 is located on the upper side of the fourth main beam 1162, the seventh pipe 1133 is located on the upper side of the eighth pipe 1134, the fifth pipe 1131 and the sixth pipe 1132 are both located on the upper side of the seventh pipe 1133, and the second sheet metal part 1135 is located on the lower side of the seventh pipe 1133 and on the upper side of the eighth pipe 1134. With the above configuration, the first pillar 111, second pillar 112, third pillar 113, fourth pillar 114, upper main beam 115, and 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, second pillar 112, third pillar 113, fourth pillar 114, upper main beam 115, and lower main beam 116—specifically by replacing tubular components with sheet metal structures—the number of tubular components in the vehicle frame 11 is reduced, thereby lowering the weight of the all-terrain vehicle 100 and achieving lightweighting of both the vehicle frame 11 and the all-terrain vehicle 100. Specifically, replacing the tubular components of the lower half of the first pillar 111 with sheet metal parts facilitates the fixed connection of the first pillar 111, and the sheet metal parts facilitate the installation of components of the all-terrain vehicle 100, improving the assemblability of the all-terrain vehicle 100. Specifically, some tubular components of the third pillar 113 are replaced with sheet metal parts. The above-described configuration reduces the need for mounting structures, improves the integration of the frame 11, and facilitates the lightweighting of the frame 11. In this embodiment, the frame 11 can be made of a high-strength 20CrMo material, thereby increasing the strength of the frame 11 and reducing its weight.

[0033] In 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 substantially symmetrical about the symmetry plane 101. The frame 11 is also substantially symmetrical about the symmetry plane 101. Specifically, the first pipe 1111 and the second pipe 1112 are substantially symmetrical about the symmetry plane 101, the third pipe 1121 and the fourth pipe 1122 are substantially symmetrical about the symmetry plane 101, the fifth pipe 1131 and the sixth pipe 1132 are substantially symmetrical about the symmetry plane 101, the ninth pipe 1141 and the tenth pipe 1142 are substantially symmetrical about the symmetry plane 101, the first main beam 1151 and the second main beam 1152 are substantially symmetrical about the symmetry plane 101, and the third main beam 1161 and the fourth main beam 1162 are substantially symmetrical about the symmetry plane 101. In this embodiment, the seventh pipe 1133 extends substantially in the left-right direction, and the eighth pipe 1134 extends substantially in the left-right direction.

[0034] In one implementation, the first strut 111, the second strut 112, the upper main beam 115, and the lower main beam 116 form a first space; the second strut 112, the third strut 113, the upper main beam 115, and the lower main beam 116 form a second space; and the third strut 113, the fourth strut 114, the upper main beam 115, and the lower main beam 116 form a third space.

The second sheet metal part 1135 includes a first sheet metal part 1135a and a second sheet metal part 1135b. The first sheet metal part 1135a is at least partially disposed between the seventh pipe 1133 and the eighth pipe 1134, and the second sheet metal part 1135b is at least partially disposed between the seventh pipe 1133 and the eighth pipe 1134. Specifically, along the vertical direction of the all-terrain vehicle 100, the upper end of the first sheet metal part 1135a is connected to one end of the seventh pipe 1133, and the lower end of the first sheet metal part 1135a is connected to one end of the eighth pipe 1134; the upper end of the second sheet metal part 1135b is connected to the other end of the seventh pipe 1133, and the lower end of the second sheet metal part 1135b is connected to the other end of the eighth pipe 1134. In this embodiment, the upper end of the second sheet metal part 1135 is provided with a mounting groove 1135c, and the lower end of the second sheet metal part 1135 is provided with a connector 1135d. In this embodiment, the second sheet metal part 1135 and the mounting groove 1135c can be integrally formed or connected by welding; the second sheet metal part 1135 and the connector 1135d can be integrally formed or connected by welding.

[0036] The second sheet metal part 1135 and the seventh pipe part 1133 are connected by a mounting groove 1135c, meaning that the seventh pipe part 1133 is at least partially disposed in the mounting groove 1135c, thereby achieving a stable connection between the second sheet metal part 1135 and the seventh pipe part 1133. The seventh pipe part 1133 can be installed in the mounting groove 1135c by welding. The second sheet metal part 1135 and the eighth pipe part 1134 are connected by a connector 1135d, thereby achieving a stable connection between the second sheet metal part 1135 and the eighth pipe part 1134. The eighth pipe part 1134 and the connector 1135d are connected by welding.

[0037] Specifically, the mounting slot 1135c includes a first mounting slot and a second mounting slot. The upper end of the first sheet metal 1135a is provided with the first mounting slot, and the upper end of the second sheet metal 1135b is provided with the second mounting slot. The connector 1135d includes a first connector and a second connector. The lower end of the first sheet metal 1135a is provided with the first connector, and the lower end of the second sheet metal 1135b is provided with the second connector. The first sheet metal 1135a is connected to one end of the seventh pipe 1133 through the first mounting slot, and the second sheet metal 1135b is connected to the other end of the seventh pipe 1133 through the second mounting slot. The first sheet metal 1135a is connected to one end of the eighth pipe 1134 through the first connector, and the second sheet metal 1135b is connected to the other end of the eighth pipe 1134 through the second connector. Through the above-described configuration, the connection between the second sheet metal part 1135 and the seventh pipe part 1133, and the connection between the second sheet metal part 1135 and the eighth pipe part 1134, are made more stable, thereby improving the connection stability of the all-terrain vehicle 100. In this embodiment, the lower side of the seventh pipe part 1133 is at least partially disposed in the mounting groove 1135c. The inner contour of the mounting groove 1135c is substantially consistent with the outer contour of the lower side of the seventh pipe part 1133, which facilitates the placement of the seventh pipe part 1133 in the mounting groove 1135c and promotes a stable connection between the seventh pipe part 1133 and the second sheet metal part 1135. It is understood that the inner contour of the first mounting groove is substantially consistent with the outer contour of the lower side of the seventh pipe part 1133, and the inner contour of the second mounting groove is substantially consistent with the outer contour of the lower side of the seventh pipe part 1133.

[0038] As one implementation, the rear suspension 132 includes a rear swing arm 1321. The rear swing arm 1321 is at least partially mounted on the frame 11. A first mounting hole 1135e is provided on the second sheet metal part 1135. The rear swing arm 1321 is connected to the frame 11 through the first mounting hole 1135e. It is understood that the rear swing arm 1321 is connected to the second sheet metal part 1135 through the first mounting hole 1135e. Specifically, the first mounting hole 1135e is at least partially located between the seventh tube 1133 and the eighth tube 1134. Through this arrangement, the mounting point of the rear swing arm 1321 can be located between the seventh tube 1133 and the eighth tube 1134, thereby eliminating the bending moment of the second sheet metal part 1135, improving the stress distribution on the second sheet metal part 1135, increasing the strength and rigidity of the second sheet metal part 1135, and consequently increasing the strength and rigidity of the frame 11, which is beneficial for extending the service life of the all-terrain vehicle 100.

[0039] In this embodiment, along the front-rear and up-down directions of the all-terrain vehicle 100, the intersection of the front and lower sides of the seventh pipe component 1133 is the first straight line 1133a, and the intersection of the rear and lower sides of the seventh pipe component 1133 is the second straight line 1133b. The intersection of the front and upper sides of the eighth pipe component 1134 is the third straight line 1134a, and the intersection of the rear and upper sides of the eighth pipe component 1134 is the fourth straight line 1134b. The first straight line 1133a, the second straight line 1133b, the third straight line 1134a, and the fourth straight line 1134b all extend substantially along the left-right direction of the all-terrain vehicle 100. The all-terrain vehicle 100 includes a symmetrical plane 101 perpendicular to the left-right direction. Along the left-right direction of the all-terrain vehicle 100, the projection of the first straight line 1133a onto the symmetry plane 101 is the first projection point; the projection of the second straight line 1133b onto the symmetry plane 101 is the second projection point; the projection of the third straight line 1134a onto the symmetry plane 101 is the third projection point; and the projection of the fourth straight line 1134b onto the symmetry plane 101 is the fourth projection point. The first, second, third, and fourth projection points form a first projection plane. The axis of the first mounting hole 1135e extends substantially along the left-right direction of the all-terrain vehicle 100. Along the left-right direction of the all-terrain vehicle 100, the projection of the first mounting hole 1135e onto the symmetry plane 101 is the second projection plane. The second projection plane is located within the first projection plane, meaning the first projection plane completely covers the second projection plane. With the above configuration, the first mounting hole 1135e can be located between the seventh tube 1133 and the eighth tube 1134, that is, the mounting point of the rear rocker arm 1321 can be set between the seventh tube 1133 and the eighth tube 1134, thereby eliminating the bending moment of the second sheet metal part 1135, making the second sheet metal part 1135 better under stress, improving the strength and rigidity of the second sheet metal part 1135, and thus improving the strength and rigidity of the frame 11, which is beneficial to improving the service life of the all-terrain vehicle 100.

[0040] As one implementation, the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface is greater than or equal to 12.5 and less than or equal to 23.4. Specifically, the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface is greater than or equal to 14.3 and less than or equal to 21.6. In this embodiment, the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface is greater than or equal to 16.1 and less than or equal to 19.8. Through the above settings, the connection between the first mounting hole 1135e and the rear rocker arm 1321 can be made more stable, and the force exerted by the first mounting hole 1135e on the second sheet metal part 1135 is more uniform, thereby improving the stress on the second sheet metal part 1135 and increasing its strength and rigidity.

[0041] As one implementation, the rear rocker arm 1321 is provided with a second mounting hole 1321a. The first mounting hole 1135e and the second mounting hole 1321a can be connected by bolts, thereby connecting the rear rocker arm 1321 and the second sheet metal part 1135. The second sheet metal part 1135 has first mounting holes 1135e on both its left and right sides. The second mounting hole 1321a is located at one end of the rear rocker arm 1321, and this end of the rear rocker arm 1321 with the second mounting hole 1321a is designated as the first end, with the second mounting hole 1321a extending through both sides of the first end. Specifically, the first mounting hole 1135e and the second mounting hole 1321a are connected by a pin. In this embodiment, the pin enters the second mounting hole 1321a from the first mounting hole 1135e on one side of the second sheet metal part 1135, and then enters the first mounting hole 1135e on the other side of the second sheet metal part 1135 from the second mounting hole 1321a, thereby achieving a stable connection between the rear rocker arm 1321 and the second sheet metal part 1135. In this embodiment, the first mounting hole 1135e includes a first hole and a second hole. The first sheet metal part 1135a has first holes on both its left and right sides, and the second sheet metal part 1135b has second holes on both its left and right sides. The rear rocker arm 1321 includes a first rocker arm 1321b and a second rocker arm 1321c. The second mounting hole 1321a includes a third hole and a fourth hole. One end of the first rocker arm 1321b has a third hole, and one end of the second rocker arm 1321c has a fourth hole. The first hole and the third hole are connected by a pin, and the second hole and the fourth hole are connected by a pin. Through the above configuration, the first rocker arm 1321b and the first sheet metal part 1135a can be stably connected, and the second rocker arm 1321c and the second sheet metal part 1135b can be stably connected, thereby achieving a stable connection between the second sheet metal part 1135 and the rear rocker arm 1321. Furthermore, through the above configuration, the mounting point of the first rocker arm 1321b can be located between the seventh pipe fitting 1133 and the eighth pipe fitting 1134, and the mounting point of the second rocker arm 1321c can be located between the seventh pipe fitting 1133 and the eighth pipe fitting 1134, thereby eliminating the bending moment of the second sheet metal part 1135, improving the stress distribution of the second sheet metal part 1135, and enhancing its strength and rigidity.

[0042] like Figure 5 and Figure 6As shown, in one implementation, the suspension assembly 13 includes a stabilizer bar 133. A plurality of balance supports 134 are provided on the stabilizer bar 133, and the stabilizer bar 133 is connected to the vehicle frame 11 through the plurality of balance supports 134. Each balance support 134 includes a support housing 1341, a first pressure block 1342, and a second pressure block 1343. The first pressure block 1342 and the second pressure block 1343 abut against each other to form a pressure block assembly, which is at least partially disposed within the support housing 1341. Specifically, the support housing 1341 includes a U-shaped portion 1341a and a connecting portion 1341b. The connecting portion 1341b is disposed on the U-shaped portion 1341a for connecting the balance support 134 and the vehicle frame 11. The U-shaped portion 1341a forms a first receiving space 1341c, and the pressure block assembly is at least partially disposed within the first receiving space 1341c. The U-shaped portion 1341a and the connecting portion 1341b are integrally formed. Understandably, the U-shaped portion 1341a and the connecting portion 1341b can also be connected by welding. In this embodiment, the outer contour of the pressure block assembly and the inner contour of the U-shaped portion 1341a are basically the same, thereby making the installation of the pressure block assembly and the U-shaped portion 1341a more stable. The inner contour of the U-shaped portion 1341a refers to the contour of the first receiving space 1341c. A connecting hole 1341d is provided on the connecting portion 1341b, and the connecting portion 1341b and the frame 11 are connected through the connecting hole 1341d, thereby achieving a stable connection between the balance support 134 and the frame 11.

[0043] In this embodiment, a first groove edge 1342a is provided at the outer surface edge of the first pressing block 1342, and a second groove edge 1343a is provided at the outer surface edge of the second pressing block 1343. The first groove edge 1342a and the first pressing block 1342 are integrally formed, and the second groove edge 1343a and the second pressing block 1343 are integrally formed. After the first pressing block 1342 and the second pressing block 1343 abut against each other, the first groove edge 1342a and the second groove edge 1343a form a pressing block groove edge. Wherein, when the pressing block assembly is disposed in the first receiving space 1341c, the outer surface of the first pressing block 1342 refers to the surface of the first pressing block 1342 in contact with the U-shaped portion 1341a, and the outer surface of the second pressing block 1343 refers to the surface of the second pressing block 1343 in contact with the U-shaped portion 1341a. A recessed edge 1341e is formed at the inner surface edge of the support housing 1341, recessed outward from the outer surface. When the pressure block assembly is disposed in the first receiving space 1341c, the inner surface of the support housing 1341 refers to the surface of the support housing 1341 that contacts the pressure block assembly, and the outer surface of the support housing 1341 refers to the surface of the support housing 1341 that is away from the pressure block assembly. During the assembly of the pressure block assembly and the support housing 1341, the pressure block groove is at least partially disposed in the recessed edge 1341e, thereby making the assembly of the pressure block assembly and the support housing 1341 more stable, preventing abnormal wear and shaking of the pressure block assembly in the first receiving space 1341c, and thus improving the service life of the balance support 134.

[0044] Specifically, the first pressure block 1342 is provided with a first receiving groove 1342b, and the second pressure block 1343 is provided with a second receiving groove 1343b. When the first pressure block 1342 and the second pressure block 1343 abut against each other, the first receiving groove 1342b and the second receiving groove 1343b form a second receiving space 1344, and the stabilizer bar 133 is at least partially disposed in the second receiving space 1344. The second receiving space 1344 is used to fix the stabilizer bar 133, thereby connecting the stabilizer bar 133 to the frame 11 through the balance support 134.

[0045] In this embodiment, the pressure block assembly includes a first end and a second end. The end face of the first end of the pressure block assembly is substantially U-shaped, thereby allowing the pressure block assembly to be better positioned within the U-shaped portion 1341a. The end face of the second end of the pressure block assembly is substantially flat, thereby allowing the second end to better conform to the frame 11, thus achieving a stable connection between the balance support 134 and the frame 11. Specifically, the first end is positioned close to the U-shaped portion 1341a, and the second end is positioned away from the U-shaped portion 1341a.

[0046] The first pressure block 1342 is provided with a weight reduction groove 1345, and the second pressure block 1343 is also provided with a weight reduction groove 1345. The weight reduction groove 1345 is located on the second end, which is conducive to the weight reduction of the pressure block assembly, thereby realizing the lightweighting of the balance support 134.

[0047] Specifically, the first pressing block 1342 is further provided with a first recess 1342c, and the second pressing block 1343 is further provided with a first protrusion 1343c. When the first pressing block 1342 and the second pressing block 1343 abut together, the first recess 1342c and the first protrusion 1343c form a sealing structure, which is used to seal the gap formed after the first pressing block 1342 and the second pressing block 1343 abut together. At this time, the first protrusion 1343c is at least partially disposed in the first recess 1342c. Through the above arrangement, the abutment of the first pressing block 1342 and the second pressing block 1343 can be made more stable, thereby preventing abnormal wear and shaking between the first pressing block 1342 and the second pressing block 1343. Furthermore, the cooperation between the first notch 1342c and the first protrusion 1343c can improve the sealing effect at the contact point between the first pressure block 1342 and the second pressure block 1343, thereby preventing mud and sand from entering the balance support 134 and thus improving the service life of the balance support 134.

[0048] In this embodiment, the first notch 1342c is disposed on the side of the first receiving groove 1342b near the second end of the pressure block assembly, and the first protrusion 1343c is disposed on the side of the second receiving groove 1343b near the second end of the pressure block assembly. That is, when the balance support 134 and the frame 11 are connected, the first notch 1342c is disposed near the frame 11, and the first protrusion 1343c is disposed near the frame 11. Since the first end is disposed in the U-shaped portion 1341a, the sealing effect of the first end of the pressure block assembly is better, and the second end of the pressure block assembly is basically exposed to the outside. Therefore, through the above arrangement, the sealing effect of the second end of the pressure block assembly can be better, thereby improving the sealing effect at the contact point of the first pressure block 1342 and the second pressure block 1343, and effectively preventing mud and sand from entering the pressure block assembly through the contact point of the first pressure block 1342 and the second pressure block 1343.

[0049] Understandably, the first notch 1342c can also be set on the second pressing block 1343, and the first protrusion 1343c can also be set on the first pressing block 1342.

[0050] As one implementation, a first oil passage 1346 is also provided on the first end of the pressure block assembly. The first oil passage 1346 includes a first half-hole and a second half-hole, which are connected to form the first oil passage 1346. The first half-hole is provided on the first pressure block 1342, and the second half-hole is provided on the second pressure block 1343. The first half-hole and the second half-hole together form the first oil passage 1346. The first half-hole connects to the first receiving groove 1342b, and the second half-hole connects to the second receiving groove 1343b. A second oil passage 1341f is provided on the U-shaped part 1341a. The axis of the second oil passage 1341f is substantially coincident with the axis of the first oil passage 1346. One end of the second oil passage 1341f connects to the first oil passage 1346, and the other end of the second oil passage 1341f connects to the outside. Specifically, the first oil passage 1346 and the second oil passage 1341f are used to deliver lubricating oil to the balance support 134, thereby lubricating the stabilizer bar 133 and the balance support 134. In this embodiment, lubricating oil enters the first oil passage 1346 from the second oil passage 1341f, thereby delivering the lubricating oil from the support housing 1341 to the pressure block assembly, thus improving the lubrication effect of the balance support 134.

[0051] In this embodiment, an oil reservoir 1347 is also provided on the inner surface of the first pressure block 1342, and an oil reservoir 1347 is also provided on the inner surface of the second pressure block 1343. The oil reservoir 1347 is connected to the first oil passage 1346 and is used to store the lubricating oil delivered to the pressure block assembly, thereby improving the lubrication effect of the balance support 134. The oil reservoir 1347 is basically cross-shaped, that is, the oil reservoir 1347 includes a horizontal groove and a vertical groove, which are connected. One end of the horizontal groove is connected to the first oil passage 1346, so that the lubricating oil can flow from the first oil passage 1346 into the horizontal groove, and then the lubricating oil flows into the vertical groove through the horizontal groove, thereby improving the lubrication effect and oil storage capacity of the oil reservoir 1347.

[0052] like Figure 6 and Figure 7 As shown, in one implementation, the stabilizer bar 133 includes a first torsion bar 1331 and a second torsion bar 1332. The first torsion bar 1331 is at least partially disposed on the front side of the frame 11, and the second torsion bar 1332 is at least partially disposed on the rear side of the frame 11. The balance support 134 includes a first support 1348 and a second support 1349. The first torsion bar 1331 is mounted on the frame 11 via the first support 1348, and the second torsion bar 1332 is mounted on the frame 11 via the second support 1349. Specifically, the frame 11 includes a first frame 11a. The upper main beam 115, the first pillar 111, the lower main beam 116, and the second pillar 112 form the first frame 11a. The first support 1348 is disposed on the first frame 11a. The upper main beam 115, located between the first support column 111 and the second support column 112, forms the first crossbeam 1153, with one end of the first crossbeam 1153 connected to one end of the first support column 111 and the other end of the first crossbeam 1153 connected to one end of the second support column 112. The lower main beam 116, located between the first support column 111 and the second support column 112, forms the second crossbeam 1163, with one end of the second crossbeam 1163 connected to the other end of the first support column 111 and the other end of the second crossbeam 1163 connected to the other end of the second support column. The first crossbeam 1153, the first support column 111, the second crossbeam 1163, and the second support column 112 form the first frame 11a. With the above configuration, the first support 1348 can be mounted on the first frame 11a, thereby setting the mounting point of the first torsion bar 1331 on the first frame 11a, which improves the space utilization of the all-terrain vehicle 100, enhances the performance of the first torsion bar 1331, and prevents the first torsion bar 1331 from affecting other components of the all-terrain vehicle 100.

[0053] In this embodiment, since the frame 11 is provided with a first support column 111, a second support column 112, an upper main beam 115, and a lower main beam 116 on both the left and right sides, the first frame 11a includes a first left frame on the left and a first right frame on the right. The first left frame and the first right frame enclose a first space 11aa, and a first support 1348 is disposed in the first space 11aa and on the frame 11. That is, the first support 1348 is disposed at any point on the frame 11 in the first space 11aa.

[0054] Specifically, the frame 11 also includes a second frame 11b. The upper main beam 115, the third pillar 113, the lower main beam 116, and the fourth pillar 114 form the second frame 11b. A second support 1349 is mounted on the second frame 11b. The portion of the upper main beam 115 between the third pillar 113 and the fourth pillar 114 is the third crossbeam 1154, with one end connected to one end of the third pillar 113 and the other end connected to one end of the fourth pillar 114. The portion of the lower main beam 116 between the third pillar 113 and the fourth pillar 114 is the fourth crossbeam 1164, with one end connected to the other end of the third pillar 113 and the other end connected to the other end of the fourth pillar 114. The third crossbeam 1154, the third pillar 113, the fourth crossbeam 1164, and the fourth pillar 114 form the second frame 11b. Furthermore, the frame 11 also includes a third frame 11c (see reference). Figure 4 The third frame 11c is positioned between the third main beam 1161 and the fourth main beam 1162, with one end connected to the third main beam 1161 and the other end connected to the fourth main beam 1162. Along the longitudinal direction of the all-terrain vehicle 100, the third frame 11c is also positioned behind and connected to the eighth pipe fitting 1134. The second support 1349 can also be positioned on the third frame 11c. Through these arrangements, the second support 1349 can be positioned on either the second frame 11b or the third frame 11c, thereby setting the mounting point of the second torsion bar 1332 on either the second frame 11b or the third frame 11c. This improves the space utilization of the all-terrain vehicle 100, enhances the performance of the second torsion bar 1332, and prevents the second torsion bar 1332 from affecting other components of the all-terrain vehicle 100.

[0055] In this embodiment, since the frame 11 is provided with a third support column 113, a fourth support column 114, an upper main beam 115, and a lower main beam 116 on both the left and right sides, the second frame 11b includes a second left frame on the left and a second right frame on the right. The second left frame and the second right frame enclose a second space 11ba, and a second support 1349 is disposed in the second space 11ba and on the frame 11. That is, the second support 1349 is disposed at any point on the frame 11 in the second space 11ab.

[0056] like Figure 8 As shown, in one implementation, the foot pedal assembly 19 is at least partially mounted on the frame 11 to provide foot support for the user and / or passenger. Specifically, the foot pedal assembly 19 includes a first foot pedal 191 and a second foot pedal (not shown in the figure). The first foot pedal 191 is located on the left side of the all-terrain vehicle 100 and is at least partially connected to the third main beam 1161. The second foot pedal is located on the right side of the all-terrain vehicle 100 and is at least partially connected to the fourth main beam 1162. It can be understood that the first foot pedal 191 and the second foot pedal have essentially the same structure; only the first foot pedal 191 will be described in detail below. In this embodiment, the first foot pedal 191 includes a support frame 1911, a connecting frame 1912, an extension frame 1913, and a footrest 1914. A mounting member 1161a is provided on the third main beam 1161. One end of the support frame 1911 is connected to the third main beam 1161, and the other end of the support frame 1911 is connected to the footrest 1914. A connecting frame 1912 connects the support frame 1911 and the third main beam 1161. An extension frame 1913 is at least partially mounted on the support frame 1911 for mounting other components of the all-terrain vehicle 100. A footrest 1914 connects to the support frame 1911 and provides foot support for the passenger. The footrest 1914 is at least partially mounted on the upper side of the support frame 1911 for easy placement of the passenger's feet. A mounting member 1161a connects the third main beam 1161 and the connecting frame 1912, facilitating a stable connection between the third main beam 1161 and the connecting frame 1912, thereby making the connection between the footrest assembly 19 and the frame 11 more stable.

[0057] In this embodiment, the support frame 1911 includes a first connecting pipe 1911a, a second connecting pipe 1911b, and a third connecting pipe 1911c. The first connecting pipe 1911a, second connecting pipe 1911b, and third connecting pipe 1911c are fixedly connected or integrally formed. One end of the first connecting pipe 1911a is connected to the third main beam 1161, the other end of the first connecting pipe 1911a is connected to one end of the second connecting pipe 1911b, the other end of the second connecting pipe 1911b is connected to the third connecting pipe 1911c, and the other end of the third connecting pipe 1911c is connected to one end of the footrest 1914. The other end of the third connecting pipe 1911c extends upward and connects to one end of the footrest 1914, and the other end of the footrest 1914 is connected to the seventh pipe fitting 1133. The mounting member 1161a is located on the front side of the footrest 1914, that is, on the front side of the third support column 113. One end of the connecting frame 1912 is connected to the second connecting pipe 1911b, and the other end is connected to the third main beam 1161. The extension frame 1913 is at least partially mounted on the second connecting pipe 1911b. This configuration allows for the integration of the pedal assembly 19, enabling the pedal frame 1914 to be directly connected to the frame 11, thereby increasing the strength of the pedal frame 1914 and simplifying the assembly of the pedal assembly 19 and the frame 11, thus improving the assemblability of the all-terrain vehicle 100. Furthermore, this configuration also reduces the volume and weight of the pedal assembly 19, thereby improving its lightweight design and consequently the lightweight design of the all-terrain vehicle 100.

[0058] In one implementation, the first connecting pipe 1911a and the third main beam 1161 can be bolted together, the connecting frame 1912 and the mounting piece 1161a can be bolted together, and the footrest 1914 and the seventh pipe fitting 1133 can be bolted together. The footrest 1914 and the third connecting pipe 1911c are welded together, and the extension frame 1913 and the second connecting pipe 1911b are welded together. Specifically, the mounting frame assembly 16 includes a mounting bracket 166 for fixing the power assembly 14. The mounting bracket 166 is at least partially disposed between the third main beam 1161 and the fourth main beam 1162, and is disposed on the front side of the mounting piece 1161a. One end of the mounting bracket 166 is connected to the third main beam 1161, and the other end is connected to the fourth main beam 1162. The first connecting pipe 1911a and the third main beam 1161 are connected by the mounting bracket 166. The end of the mounting bracket 166 connected to the third main beam 1161 is the first connecting end. The first connecting pipe 1911a and the first connecting end are connected by bolts, thereby connecting the first connecting pipe 1911a and the mounting bracket 166, and thus fixing the first connecting pipe 1911a and the third main beam 1161.

[0059] As one implementation, the first foot pedal 191 and the second foot pedal are arranged symmetrically with respect to the all-terrain vehicle 100. Specifically, the connection or positional relationship of the second foot pedal is basically the same as that of the first foot pedal 191, and will not be elaborated here.

[0060] like Figures 9 to 11 As shown, in one implementation, the frame 11 also includes a plurality of sealing members 117. The plurality of sealing members 117 are at least partially disposed on the frame 11 and at least partially disposed on the mounting bracket assembly 16, for sealing the openings of the tubes on the frame 11 and / or the mounting bracket assembly 16. Specifically, the openings of the tubes on the frame 11 refer to the openings at both ends of the first pillar 111 and / or the second pillar 112 and / or the third pillar 113 and / or the fourth pillar 114 and / or the upper main beam 115 and / or the lower main beam 116, etc., meaning that sealing members 117 can be provided on the openings of the tubes constituting the frame 11; the openings of the tubes on the mounting bracket assembly 16 refer to the openings of the bumper mechanism 165, etc., meaning that sealing members 117 can be provided on the openings of the tubes constituting the mounting bracket assembly 16. In this embodiment, the frame 11 and the mounting bracket assembly 16 constitute the frame assembly 102.

[0061] As one implementation, the sealing member 117 is provided with a mounting hole, the axis of which is substantially coincident with the axis of the sealing member 117. The mounting hole can serve as a leakage hole for the all-terrain vehicle 100 or as a mounting hole for components of the all-terrain vehicle 100. The ratio of the cross-sectional area of ​​the tube of the frame assembly 102 to the cross-sectional area of ​​the mounting hole is greater than or equal to 4 and less than or equal to 71. Specifically, the ratio of the cross-sectional area of ​​the tube of the frame assembly 102 to the cross-sectional area of ​​the mounting hole is greater than or equal to 5 and less than or equal to 64. In this embodiment, the ratio of the cross-sectional area of ​​the tube of the frame assembly 102 to the cross-sectional area of ​​the mounting hole is greater than or equal to 6 and less than or equal to 57. Furthermore, the ratio of the cross-sectional area of ​​the tube of the frame assembly 102 to the cross-sectional area of ​​the mounting hole is greater than or equal to 15 and less than or equal to 20. Through the above settings, while satisfying the leakage and installation functions of the mounting hole, the impact of the mounting hole on the strength of the sealing member 117 can be reduced, thereby improving the strength and service life of the sealing member 117.

[0062] Specifically, the sealing element 117 includes a first sealing element 1171 and / or a second sealing element 1172 and / or a third sealing element 1173.

[0063] like Figure 9As shown, in one implementation, the first plug 1171 can be disposed on the tube of the frame assembly 102. The cross-section of the first plug 1171 is substantially circular. Specifically, the inner diameter of the first plug 1171 is greater than or equal to the outer diameter of the tube of the frame assembly 102. Through the above arrangement, the first plug 1171 is at least partially disposed around the tube of the frame assembly 102, thereby allowing the first plug 1171 to be fitted onto the tube of the frame assembly 102, facilitating a stable connection between the first plug 1171 and the tube of the frame assembly 102. Specifically, the edge of the first plug 1171 near the tube of the frame assembly 102 extends toward the tube of the frame assembly 102 and forms an annulus 1171a, which is fitted onto the tube of the frame assembly 102, thereby making the connection between the tube of the frame assembly 102 and the first plug 1171 more stable. The first plug 1171 is fitted onto the tube of the frame assembly 102, and the tube of the frame assembly 102 and the first plug 1171 are fixedly connected by welding.

[0064] In this embodiment, the first plug 1171 is provided with a first mounting hole 1171b and a first slot 1171c. The axis of the first mounting hole 1171b and the axis of the first plug 1171 are substantially coincident, and the first mounting hole 1171b can serve as a drain hole for the all-terrain vehicle 100. The first slot 1171c is located at the edge of the first plug 1171 and is used to drain liquids such as electrophoretic fluid from the pipes of the frame assembly 102, i.e., the first slot 1171c can serve as a drain hole. The first mounting hole 1171b can serve as a mounting hole for components of the all-terrain vehicle 100. Through the above arrangement, mounting holes for components of the all-terrain vehicle 100 can be integrated on the first plug 1171, thereby reducing the mounting structure of the components of the all-terrain vehicle 100, and thus reducing the weight of the all-terrain vehicle 100, achieving lightweighting of the all-terrain vehicle 100.

[0065] like Figure 10As shown, in one implementation, the second plug 1172 can be disposed on the tube of the frame assembly 102. The cross-section of the second plug 1172 is substantially circular. Specifically, the outer diameter of the second plug 1172 is less than or equal to the inner diameter of the tube of the frame assembly 102. Through the above arrangement, the second plug 1172 can be at least partially disposed within the tube of the frame assembly 102, thereby facilitating a stable connection between the second plug 1172 and the tube of the frame assembly 102. Specifically, the edge of the second plug 1172 is provided with a plurality of protrusions 1172a, and the tube of the frame assembly 102 is provided with a plurality of recesses 1021. When the second plug 1172 is connected to the tubing of the frame assembly 102, the protrusion 1172a is at least partially disposed in the recess 1021. The recess 1021 is used to limit the protrusion 1172a, thereby limiting the tubing of the frame assembly 102 to the second plug 1172, which is beneficial to the stable connection between the tubing of the frame assembly 102 and the second plug 1172. After the protrusion 1172a and the recess 1021 are assembled, the tubing of the frame assembly 102 and the second plug 1172 can be fixedly connected by welding. In this embodiment, the second plug 1172 is provided with a second mounting hole 1172b and a wire harness cable tie 1172c. The axis of the second mounting hole 1172b is substantially coincident with the axis of the second plug 1172. The second mounting hole 1172b can serve as a drain hole for the all-terrain vehicle 100. The cable tie 1172c is connected to the second mounting hole 1172b and the second plug 1172, meaning that the cable tie 1172c is at least partially disposed in the second mounting hole 1172b. The cable tie 1172c is used to secure the wiring harness of the all-terrain vehicle 100. Specifically, the cable tie 1172c includes a fixing plate and a cable tie. The cable tie is disposed on the fixing plate and on one side of the fixing plate, and the other side of the fixing plate is connected to the second mounting hole 1172b, thereby achieving the connection between the second mounting hole 1172b and the cable tie 1172c. In this embodiment, the cable tie 1172c can be installed or removed according to actual needs, thereby meeting the diverse needs of the all-terrain vehicle 100. Through the above arrangement, the mounting hole of the cable tie 1172c can be integrated into the second plug 1172, thereby reducing the fixing structure of the wiring harness of the all-terrain vehicle 100, thus reducing the weight of the all-terrain vehicle 100 and achieving lightweighting of the all-terrain vehicle 100.

[0066] like Figure 11As shown, as one implementation, the third plug 1173 can be disposed on the tube of the frame assembly 102. The third plug 1173 includes a mounting portion 1173a and a fixing portion 1173b. The mounting portion 1173a is at least partially connected to the fixing portion 1173b. Specifically, the mounting portion 1173a and the fixing portion 1173b can be integrally formed or connected by welding. The cross-section of the fixing portion 1173b is substantially circular. Specifically, the outer diameter of the fixing portion 1173b is substantially the same as the outer diameter of the tube of the frame assembly 102. With the above arrangement, the edge of the fixing portion 1173b fits against the edge of the tube of the frame assembly 102, thereby making the connection between the fixing portion 1173b and the tube of the frame assembly 102 more stable. The fixing portion 1173b and the tube of the frame assembly 102 are connected by welding, that is, the third plug 1173 and the tube of the frame assembly 102 can be connected by welding. A third mounting hole 1173c is provided on the fixing part 1173b, and the axis of the third mounting hole 1173c is substantially coincident with the axis of the fixing part 1173b. The third mounting hole 1173c can serve as a drainage hole for the all-terrain vehicle 100. A fixing hole 1173d is provided on the mounting part 1173a, and the fixing hole 1173d is used to install other components of the all-terrain vehicle 100. With the above configuration, the mounting holes of other components of the all-terrain vehicle 100 can be integrated on the third plug 1173, thereby reducing the mounting structure of the components of the all-terrain vehicle 100, and thus reducing the weight of the all-terrain vehicle 100, achieving lightweighting of the all-terrain vehicle 100. In addition, with the above configuration, the fixing hole 1173d can extend substantially along the radial direction of the tube of the frame assembly 102, thereby fixing the components of the all-terrain vehicle 100 to the side of the tube of the frame assembly 102, facilitating the installation or removal of the components of the all-terrain vehicle 100. Mounting part 1173a includes a first side plate, a second side plate, and a base plate. The first side plate, second side plate, and base plate are all mounted on the fixing part 1173b. One side of the first side plate is connected to one side of the base plate, and one side of the second side plate is connected to the other side of the base plate. The first side plate, second side plate, and base plate can be integrally formed or connected by welding. In this embodiment, fixing holes 1173d are provided on the base plate. The number of fixing holes 1173d can be adjusted according to actual needs.
