[0022] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0023] like Figure 1 An all-terrain vehicle 100 is shown, and the all-terrain vehicle 100 includes a frame 11, a suspension system 21, a traveling assembly 31 and a power system 41. The frame 11 constitutes the basic framework of the all-terrain vehicle 100, and is used to support the suspension system 21, the traveling assembly 31 and the power system 41. The suspension system 21 is at least partially connected to the frame 11, and the suspension system 21 has shock absorption, buffering and guiding functions to transmit various forces and moments between the traveling assembly 31 and the frame 11, and control various vibrations of the vehicle body. The traveling assembly 31 is connected to the frame 11 through the suspension system 21, and the traveling assembly 31 is used for the movement of the all-terrain vehicle 100. The power system 41 is supported by the frame 11 and is transmission-connected to the traveling assembly 31, and the power system 41 can drive the traveling assembly 31 to move. In order to clearly illustrate the technical solution of the application, it is also defined as follows Figure 1 In the present application, the length direction of the all-terrain vehicle 100 refers to the front-to-back direction, the width direction of the all-terrain vehicle 100 refers to the left-right direction, and the height direction of the all-terrain vehicle 100 refers to the up-down direction. It can be understood that along the height direction of the all-terrain vehicle 100, the travel assembly 31 is at least partially located below the frame 1111, so as to facilitate the movement of the travel assembly 31.

[0024] like Figure 2 and Figure 3 As shown, as an implementation, the suspension system 21 includes a front rocker arm 211 and a front torsion bar 212. The front rocker arm 211 is located in front of the frame 11 and is rotatably connected to the frame 11. The front torsion bar 212 is rotatably connected to the frame 11 and the front rocker arm 211. Specifically, the front torsion bar 212 balances the up and down bouncing of the sub-travel assembly 31 through a torsion beam to reduce the shaking of the vehicle and keep the vehicle stable, thereby improving the driving stability of the all-terrain vehicle 100. Among them, the front rocker arm 211 includes a front upper rocker arm 2111 and a front lower rocker arm 2112 distributed along the height direction of the all-terrain vehicle 100. The front torsion bar 212 is located between the front upper rocker arm 2111 and the front lower rocker arm 2112, and the front torsion bar 212 is connected to the front upper rocker arm 2111. Through the above arrangement, the structure of the front torsion bar 212 is optimized so that the front torsion bar 212 can be arranged between the front upper rocker arm 2111 and the front lower rocker arm 2112, thereby making the structure of the front torsion bar 212, the front upper rocker arm 2111 and the front lower rocker arm 2112 more compact, thereby improving the structural compactness of the suspension system 21, and further improving the space utilization of the all-terrain vehicle 100.

[0025] In this embodiment, the vehicle frame 11 includes an integrated frame 111 located at the front of the vehicle frame 11, and the front rocker arm 211 and the front torsion bar 212 are rotatably connected to the integrated frame 111. Specifically, when viewed along the height direction of the all-terrain vehicle 100, the front torsion bar 212 is substantially in a "U"-shaped structure, and the front torsion bar 212 is at least partially arranged around the integrated frame 111. Through the above arrangement, the structure of the front torsion bar 212 and the integrated frame 111 is more compact, which is conducive to improving the structural compactness of the front torsion bar 212 and the integrated frame 111.

[0026] Exemplarily, at least two positioning rotating members 213 are sleeved on the front torsion bar 212, and the positioning rotating members 213 are distributed along the width direction of the all-terrain vehicle 100 and fixedly connected to the integrated frame 111, and the front torsion bar 212 is rotatably connected to the positioning rotating members 213. Specifically, the front torsion bar 212 is basically formed by bending a round tube, and the positioning rotating member 213 is provided with a round through hole matching the round tube, so that the front torsion bar 212 can rotate in the positioning rotating member 213, thereby improving the working efficiency of the front torsion bar 212.

[0027] Furthermore, an integrated connection part 1111 is provided at the front side of the integrated frame 111, and a positioning connection part 2131 corresponding to the integrated connection part 1111 is provided on the positioning rotating member 213, and the positioning connection part 2131 is detachably connected to the integrated connection part 1111 through a fastener. Specifically, the fastener can be a bolt or other parts, so that the positioning rotating member 213 can be disassembled from the integrated frame 111, thereby improving the disassembly speed of the positioning rotating member 213 and the integrated frame 111, and at the same time, the front torsion bar 212 can be connected to the integrated frame 111 through the positioning rotating member 213, so that the front torsion bar 212 can be disassembled from the frame 11 together with the positioning rotating member 213, thereby improving the disassembly efficiency of the front torsion bar 212.

[0028] As an implementation method, along the width direction of the all-terrain vehicle 100, the front upper rocker arm 2111 is rotatably connected to both sides of the integrated frame 111, and the lower end of the front upper rocker arm 2111 is provided with a rocker arm connection part 2111a, and the two ends of the front torsion bar 212 are rotatably connected to the rocker arm connection part 2111a. Specifically, the front upper rocker arm 2111 itself is directly connected to the integrated frame 111, and at the same time, the front upper rocker arm 2111 is also connected to the integrated frame 111 through the front torsion bar 212. Through the above arrangement, the connection strength between the front upper rocker arm 2111 and the integrated frame 111 can be improved, thereby improving the stability performance of the all-terrain vehicle 100.

[0029] like Figure 4As shown, as an implementation, the suspension system 21 also includes a reinforcing bracket plate 214, which is at least partially arranged around the front rocker arm 211 and fixedly connected to the front rocker arm 211. Specifically, the reinforcing bracket plate 214 is in a "U"-shaped structure, and the reinforcing bracket plate 214 is located at the lower side of the front lower rocker arm 2112 and fixedly connected to the front lower rocker arm 2112. Through the above arrangement, the structural strength of the front lower rocker arm 2112 can be improved, which is beneficial to improving the structural stability of the suspension system 21. It should be noted that the reinforcing bracket plate 214 can also surround the front upper rocker arm 2111 and be fixedly connected to the front upper rocker arm 2111, thereby also improving the structural strength of the front upper rocker arm 2111. Since the front upper rocker arm 2111 and the front lower rocker arm 2112 are connected to each other, it is beneficial to improve the structural stability of the suspension system 21.

[0030] In this embodiment, when viewed from the height direction of the all-terrain vehicle 100, the front upper rocker arm 2111, the front lower rocker arm 2112, the front torsion bar 212 and the reinforcement bracket plate 214 at least partially overlap. Through the above arrangement, the structure of the front upper rocker arm 2111, the front lower rocker arm 2112, the front torsion bar 212 and the reinforcement bracket plate 214 can be made more compact, which is beneficial to improve the structural compactness of the suspension system 21.

[0031] like Figure 3 As shown, as an implementation method, the suspension system 21 also includes a front shock absorber 215, which is located on both sides of the frame 11 along the width direction of the all-terrain vehicle 100, the upper end of the front shock absorber 215 is connected to the frame 11, the lower end of the front shock absorber 215 is connected to the front upper rocker arm 2111, and the front torsion bar 212 is at least partially located between the front shock absorbers 215. Specifically, the front shock absorber 215 and the front torsion bar 212 are both connected to the front upper rocker arm 2111 to improve the load-bearing capacity of the front upper rocker arm 2111. More specifically, since the layout space of the front upper rocker arm 2111 is limited, the front shock absorber 215 is connected to the upper end of the front upper rocker arm 2111, and the front torsion bar 212 is connected to the lower end of the front upper rocker arm 2111, thereby separating the front shock absorber 215 and the front torsion bar 212 to avoid interference between the front shock absorber 215 and the front torsion bar 212, which is beneficial to improve the rationality of the layout of the suspension system 21. In addition, the front upper rocker arm 2111 is basically located between the front shock absorber 215 and the front torsion bar 212 along the height direction of the all-terrain vehicle 100, thereby making the structure of the front torsion bar 212, the front shock absorber 215 and the front upper rocker arm 2111 more compact, which is beneficial to improve the structural compactness of the front torsion bar 212, the front shock absorber 215 and the front upper rocker arm 2111, while improving the space utilization of the all-terrain vehicle 100.

[0032] like Figure 2As shown, as an implementation, the vehicle frame 11 further includes a winch bracket 112, the winch bracket 112 is located at the front side of the integrated frame 111 and is fixedly connected to the integrated frame 111, and the front torsion bar 212 is at least partially located between the winch bracket 112 and the integrated frame 111 in the front-to-back direction of the all-terrain vehicle 100. Specifically, the winch bracket 112 has a high structural strength, and since the front torsion bar 212 has a low structural strength, the winch bracket 112 is arranged at the front side of the front torsion bar 212, so that the front torsion bar 212 can be prevented from being deformed due to the front end of the all-terrain vehicle 100 hitting a foreign object, so as to prevent the front torsion bar 212 from being damaged, thereby facilitating the practical life of the front torsion bar 212.

[0033] like Figure 5 As shown, as an implementation, the suspension system 21 includes a rear swing arm 216, a rear torsion bar 217 and a rear shock absorber 218 located at the rear of the frame 11, and the rear swing arm 216, the rear torsion bar 217 and the rear shock absorber 218 are all rotatably connected to the frame 11. Among them, a swing arm mounting plate 219 is provided on the rear swing arm 216, and the rear torsion bar 217 and the rear shock absorber 218 are both rotatably connected to the swing arm mounting plate 219. Specifically, the frame 11 is used to support the rear swing arm 216, the rear torsion bar 217 and the rear shock absorber 218, and the rear swing arm 216, the rear torsion bar 217 and the rear shock absorber 218 are also connected to the swing arm mounting plate 219 at the same time, so that the rear swing arm 216, the rear torsion bar 217 and the rear shock absorber 218 support each other, which is conducive to improving the connection strength of the rear swing arm 216, the rear torsion bar 217 and the rear shock absorber 218, and further improving the structural stability of the suspension system 21. In addition, the rear swing arm 216, the rear torsion bar 217, the rear shock absorber 218 and the frame 11 have a compact structure, which is conducive to improving the structural compactness of the suspension system 21.

[0034] In this embodiment, the rear swing arm 216 includes a rear upper swing arm 2161 and a rear lower swing arm 2162 distributed along the height direction of the all-terrain vehicle 100, and the swing arm mounting plate 219 is located between the rear upper swing arm 2161 and the rear lower swing arm 2162 and is fixedly connected to the rear lower swing arm 2162. Specifically, the swing arm mounting plate 219 is integrated on the rear lower swing arm 2162, which can improve the strength of the rear lower swing arm 2162, thereby facilitating the improvement of the connection stability between the swing arm mounting plate 219 and the rear lower swing arm 2162. At the same time, the structures of the swing arm mounting plate 219, the rear upper swing arm 2161 and the rear lower swing arm 2162 are compact, which is conducive to improving the compactness of the suspension system 21.

[0035] Exemplarily, the rocker mounting plate 219 extends substantially along the width direction of the all-terrain vehicle 100, and a rocker mounting portion 2191 is provided at one end of the rocker mounting plate 219 away from the frame 11, and a shock absorber mounting portion 2181 is provided at the lower end of the rear shock absorber 218, and the rocker mounting portion 2191 is rotatably connected to the shock absorber mounting portion 2181. Through the above arrangement, the rear shock absorber 218 can be arranged at an angle to avoid increasing the width of the frame 11, thereby facilitating the rationality of the layout of the frame 11 and the rear shock absorber 218, thereby improving the space utilization of the all-terrain vehicle 100.

[0036] It should be noted that, when viewed from the height direction of the all-terrain vehicle 100, the rear torsion bar 217 is substantially in a "U"-shaped structure, the rear torsion bar 217 is at least partially located between the rear upper rocker arm 2161 and the rear lower rocker arm 2162, and the rear torsion bar 217 is at least partially arranged around the frame 11. Through the above arrangement, the structure of the rear torsion bar 217, the rear upper rocker arm 2161, the rear lower rocker arm 2162 and the frame 11 can be made more compact, which is conducive to improving the structural compactness of the suspension system 21 and the frame 11.

[0037] As an implementation method, a swivel mounting portion 2192 is provided at one end of the rocker mounting plate 219 close to the vehicle frame 11, and torsion connecting rods 220 are provided at both ends of the rear torsion bar 217, one end of the torsion connecting rod 220 is rotatably connected to the rear torsion bar 217, and the other end of the torsion connecting rod 220 is rotatably connected to the swivel mounting portion 2192. Specifically, the rocker mounting plate 219 and the rear torsion bar 217 are both rotatably connected to the torsion connecting rod 220, and the rotation direction between the rocker mounting plate 219 and the torsion connecting rod 220 is different from the rotation direction between the rear torsion bar 217 and the torsion connecting rod 220, thereby preventing the rear torsion bar 217 from being damaged by forces in multiple directions, thereby being beneficial to protecting the rear torsion bar 217 and improving the service life of the suspension system 21.

[0038] In this embodiment, the rear shock absorber 218 is located on both sides of the frame 11 along the width direction of the all-terrain vehicle 100, the upper end of the rear shock absorber 218 is connected to the frame 11, the lower end of the rear shock absorber 218 is connected to the rear lower rocker arm 2162, and the rear torsion bar 217 and the torsion connecting rod 220 are located between the rear shock absorber 218. Through the above arrangement, the structures of the rear shock absorber 218, the rear torsion bar 217 and the torsion connecting rod 220 can be made more compact, which is conducive to improving the structural compactness of the rear shock absorber 218, the rear torsion bar 217 and the torsion connecting rod 220, and further improving the structural compactness of the suspension system 21.

[0039] As an implementation method, at least two mounting rotating members 221 are sleeved on the rear torsion bar 217, and the mounting rotating members 221 are distributed along the width direction of the all-terrain vehicle 100 and fixedly connected to the vehicle frame 11, and the rear torsion bar 217 is rotatably connected to the mounting rotating members 221. Specifically, the rear torsion bar 217 is basically formed by bending a round tube, and the mounting rotating member 221 is provided with a round through hole matching the round tube, so that the rear torsion bar 217 can rotate in the mounting rotating member 221, thereby improving the working efficiency of the rear torsion bar 217.

[0040] like Figure 2 and Figure 5 As shown, in this embodiment, a torsion bar connection part 113 is provided on the rear side of the vehicle frame 11, and a mounting connection part 2211 corresponding to the torsion bar connection part 113 is provided on the mounting rotating member 221, and the mounting connection part 2211 is detachably connected to the torsion bar connection part 113 through a fastener. Specifically, the fastener can be a bolt or other parts, so that the mounting rotating member 221 can be removed from the vehicle frame 11, thereby improving the disassembly speed of the mounting rotating member 221 and the vehicle frame 11, and at the same time, the rear torsion bar 217 can be connected to the vehicle frame 11 through the mounting rotating member 221, so that the rear torsion bar 217 can be removed from the vehicle frame 11 together with the mounting rotating member 221, thereby improving the disassembly efficiency of the rear torsion bar 217. Similarly, the rear torsion bar 217 can also be installed on the vehicle frame 11 together with the mounting rotating member 221, thereby improving the installation efficiency of the rear torsion bar 217.

[0041] As an implementation method, the reinforcing bracket plate 214 is at least partially arranged around the rear rocker arm 216 and fixedly connected to the rear rocker arm 216. Specifically, the reinforcing bracket plate 214 is located at the lower side of the rear lower rocker arm 2162 and fixedly connected to the rear lower rocker arm 2162. Since the rear lower rocker arm 2162 integrates the rocker arm mounting plate 219, the rear shock absorber 218, the rear torsion bar 217 and the torsion connecting rod 220, the structural strength of the rear lower rocker arm 2162 is required to be relatively high, and thus the reinforcing bracket plate 214 is connected to the rear lower rocker arm 2162 in the present application. Through the above arrangement, the structural strength of the rear lower rocker arm 2162 can be improved, which is conducive to improving the structural stability of the suspension system 21. It should be noted that the reinforcing bracket plate 214 can also surround the rear upper rocker arm 2161 and be fixedly connected to the rear upper rocker arm 2161, thereby further improving the structural strength of the rear upper rocker arm 2161. Since the rear upper rocker arm 2161 and the rear lower rocker arm 2162 are interconnected, it is beneficial to improve the structural stability of the suspension system 21.
