Technical Field

[0001] This application relates to the technical field of vehicles, and particularly to an all-terrain vehicle. Background Art

[0002] At present, the frame of an all-terrain vehicle is divided into an upper part and a lower part. Among them, the upper connecting frame is used to carry body components such as the upper ceiling and vehicle glass. The upper connecting frame includes a front top bar connecting pipe, a left connecting pipe, and a right connecting pipe. Among them, the left connecting pipe and the right connecting pipe are symmetrically arranged on both sides of the all-terrain vehicle, and the front top bar connecting pipe is connected to the left connecting pipe and the right connecting pipe.

[0003] In the prior art, a small part of the upper connecting frame is welded by multiple round pipes, so the assembly accuracy requirements for the frame are relatively high and it is not conducive to transportation. Most of the upper connecting frames are made of sheet metal parts. Due to the relatively weak structural strength of the sheet metal parts themselves, the structural strength of the frame is reduced. Summary of the Invention

[0004] In order to solve the deficiencies of the prior art, the purpose of this application is to provide an all-terrain vehicle with relatively high structural strength of its frame.

[0005] To achieve the above purpose, this application adopts the following technical solutions:

[0009] Furthermore, bushings are arranged in both the first connection hole and the second connection hole. The bushings are fixedly connected to the front bumper connecting pipe, and the fasteners pass through the bushings and then are connected to the front reinforcing plate and the rear reinforcing plate.

[0010] Furthermore, one end of the upper reinforcing plate away from the rear reinforcing plate extends at least partially towards the lower side of the all-terrain vehicle to form a reinforcing portion. When observed along the length direction of the all-terrain vehicle, the reinforcing portion at least partially overlaps with the front reinforcing plate and the rear reinforcing plate.

[0011] Furthermore, one end of the front reinforcing plate away from the rear reinforcing plate is arranged close to the reinforcing portion. A connecting portion is arranged on the front reinforcing plate. The connecting portion is located between the front reinforcing plate and the reinforcing portion and is fixedly connected to the front reinforcing plate. The fasteners pass through the bushing and are detachably connected to the connecting portion.

[0012] Furthermore, both the left connecting pipe and the right connecting pipe include a longitudinal bracket extending substantially along the front-rear direction of the all-terrain vehicle and a column bracket extending along the height direction of the all-terrain vehicle. The front end of the longitudinal bracket and the lower end of the column bracket are both connected to the lower support frame, and the rear end of the longitudinal bracket and the upper end of the column bracket are both connected.

[0013] Furthermore, a front-side mounting hole extending substantially along the height direction of the all-terrain vehicle is arranged at the front end of the longitudinal bracket, and a rear-side mounting hole extending substantially along the width direction of the all-terrain vehicle is arranged at the rear end of the longitudinal bracket.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the specific embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0031] As shown in Figure 1 and Figure 2 , an all-terrain vehicle 100 includes a frame 11, a running system 12, a power system 13, a suspension system 14, a braking system 15, a body covering 16, a seat system 17, a transmission system 18, and an electrical system 19. Among them, the frame 11 serves as the basic framework of the all-terrain vehicle 100 and is used to support the running system 12, the power system 13, the suspension system 14, the braking system 15, the body covering 16, the seat system 17, the transmission system 18, and the electrical system 19. The running system 12 is connected to the frame 11 through the suspension system 14. The power system 13 is drivingly connected to the running system 12 to provide driving force for the movement of the running system 12. The braking system 15 is at least partially located on the running system 12 to brake the running system 12. The body covering 16 is generally a plastic part and is used to cover and connect to the frame 11 to form the exterior part of the all-terrain vehicle 100. After the body covering 16 and the frame 11 are connected, a driving space 20 is formed. Specifically, a driving space 20 is formed between the middle part of the frame 11 and the body covering 16. The seat system 17 is located in the driving space 20 and is used to carry the driver and passengers. The transmission system 18 is drivingly connected to the power system 13, and the transmission system 18 is also drivingly connected to the running system 12, so that the driving force of the power system 13 is transmitted to the running system 12 through the transmission system 18. The electrical system 19 is at least partially arranged on the frame 11, and the electrical system 19 is used to control the electrical components on the all-terrain vehicle 100.

[0032] To clearly illustrate the technical solution of the present application, the front, rear, left, right, up, and down as shown in Figure 1 are also defined. In the present application, the length direction of the all-terrain vehicle 100 refers to the Figure 1 front-back direction in Figure 1 , the width direction of the all-terrain vehicle 100 refers to the Figure 1 left-right direction in

[0033]

[0034] Figure 3 As shown in Figure 3 and Figure 4As shown, as an implementation, the all-terrain vehicle 100 further includes a winch device 25. The winch device 25 is at least partially connected to the vehicle frame 11. Among them, the vehicle frame 11 includes an integrated frame 118 and a winch support 119 located on the front side of the vehicle frame 11. The winch device 25 is connected above the integrated frame 118. The winch support 119 is located below the winch device 25 and connected to the integrated frame 118. The above setting of the winch support 119 can improve the structural strength of the integrated frame 118, so that the integrated frame 118 can better support the winch device 25, which is beneficial to improving the connection strength between the winch device 25 and the vehicle frame 11.

[0035] Specifically, the body covering 16 includes a collision prevention panel 16a. The collision prevention panel 16a is at least partially located in front of the winch support 119 and connected to the winch support 119. The collision prevention panel 16a is connected to the integrated frame 118 through the winch support 119. Through the above setting, the connection strength between the collision prevention panel 16a and the winch support 119 can be improved. And the collision prevention panel 16a and the winch support 119 are connected by means such as bolts, so that the collision prevention panel 16a and the winch support 119 can be disassembled or installed together, which is further beneficial to improving the assembly speed of the collision prevention panel 16a and the winch support 119. It can be understood that when the collision prevention panel 16a is impacted, the winch support 119 can withstand a large impact, thus avoiding the integrated frame 118 from receiving a direct external impact, and the winch support 119 is convenient to replace, which is beneficial to improving the service life of the vehicle frame 11.

[0036] In this embodiment, the winch support 119 includes a rear winch frame 1192 connected to the integrated frame 118 and a front winch frame 1191 connected to the collision prevention panel 16a. A panel mounting portion 1191a is provided on the front winch frame 1191, and a panel connection portion 16b corresponding to the panel mounting portion 1191a is provided on the collision prevention panel 16a. The panel mounting portion 1191a and the panel connection portion 16b are detachably connected by fasteners. Specifically, the rear winch frame 1192 is used to improve the structural strength of the integrated frame 118, and the front winch frame 1191 is used to connect the collision prevention panel 16a to the integrated frame 118. Through the above setting, the winch support 119 has both the functions of support and connection, which is beneficial to improving the comprehensiveness of the functions of the winch support 119.

[0037] As an implementation, the body covering 16 includes a protective outer plate 16c. An outer plate connection portion 1191b connected to the protective outer plate 16c is provided on the front winch frame 1191. The outer plate connection portion 1191b is distributed along the width direction of the all-terrain vehicle 100. The protective outer plate 16c is at least partially located above the collision prevention panel 16a. Through the above setting, the protective outer plate 16c and the collision prevention panel 16a are more structurally compact, which is beneficial to improving the structural compactness of the protective outer plate 16c and the collision prevention panel 16a.

[0038] As an implementation, an upper winch mounting portion 1192a and a lower winch mounting portion 1192b are provided on the rear winch bracket 1192. The upper winch mounting portion 1192a is connected to the upper side of the integrated bracket 118, and the lower winch mounting portion 1192b is connected to the lower side of the integrated bracket 118. Specifically, an upper winch connection portion 1181 and a lower winch connection portion 1182 are provided on the integrated bracket 118. The upper winch connection portion 1181 is provided with an upper winch connection hole 1181a extending in the width direction of the all-terrain vehicle 100, and the lower winch connection portion 1182 is provided with a lower winch connection hole 1182a extending in the length direction of the all-terrain vehicle 100. Through the above settings, a fastener can pass through the upper winch connection hole 1181a to detachably connect the upper winch mounting portion 1192a and the upper winch connection portion 1181. Similarly, the fastener can pass through the lower winch connection hole 1182a to detachably connect the lower winch mounting portion 1192b and the lower winch connection portion 1182. This is beneficial to both improving the connection strength between the winch bracket 119 and the integrated bracket 118 and improving the assembly efficiency of the winch bracket 119 and the integrated bracket 118. It should be noted that the axis of the upper winch connection hole 1181a is perpendicularly arranged to the axis of the lower winch connection hole 1182a. Through the above settings, the force borne by the winch bracket 119 can be diffused in multiple directions, thus avoiding the output of the bearing capacity of the winch bracket 119 in the same direction, and further being beneficial to improving the connection stability between the winch bracket 119 and the integrated bracket 118.

[0039] As an implementation, the winch device 25 is connected to the upper side of the integrated bracket 118, and the winch bracket 119 is located below the winch device 25. Specifically, the winch device 25 needs to bear a large pulling force during operation, and the winch bracket 119 can improve the stability of the winch device 25, thus being beneficial to improving the connection stability between the winch device 25 and the integrated bracket 118.

[0040] As an implementation, an avoidance portion 1193 is provided on the lower side of the winch bracket 119, and a panel through-hole 16d corresponding to the avoidance portion 1193 is provided on the anti-collision panel 16a. The vehicle frame 11 includes a trailer hitch 11a, and the trailer hitch 11a passes through the panel through-hole 16d and the avoidance portion 1193 and then is connected to the vehicle frame 11. Through the above settings, the trailer hitch 11a is arranged close to the winch bracket 119, thus being beneficial to improving the structural compactness between the winch bracket 119 and the trailer hitch 11a. In addition, the vehicle frame 11 further includes an anti-collision hook 11b, and the anti-collision hook 11b is connected to the winch bracket 119. When observing along the length direction of the all-terrain vehicle 100, the winch bracket 119 is arranged around the anti-collision hook 11b. Through the above settings, the anti-collision hook 11b is located at the rear side of the anti-collision panel 16a and abuts against the anti-collision panel 16a. The anti-collision hook 11b can improve the strength of the anti-collision panel 16a and is also beneficial to improving the structural strength of the winch bracket 119.

[0041] In this embodiment, a plurality of hollow portions 1194 are provided on the winch bracket 119, and the hollow portions 1194 extend substantially along the length direction of the all-terrain vehicle 100. Through the above arrangement, the mass of the winch bracket 119 can be reduced, which is beneficial to the lightweight of the winch bracket 119, and further beneficial to the lightweight of the vehicle frame 11.

[0042] As Figure 5 and Figure 6 shown, as an implementation manner, the vehicle frame 11 includes an upper connecting frame 115 and a lower support frame 116. The upper connecting frame 115 is detachably connected to the upper side of the lower support frame 116, and the body covering 16 is at least partially connected to the upper connecting frame 115. Specifically, the upper connecting frame 115 includes a front bumper connecting pipe 1153, a left connecting pipe 1154 and a right connecting pipe 1155. The left connecting pipe 1154 and the right connecting pipe 1155 are distributed along the width direction of the all-terrain vehicle 100. The front bumper connecting pipe 1153 extends along the width direction of the all-terrain vehicle 100 and is located between the left connecting pipe 1154 and the right connecting pipe 1155. Among them, reinforcing plates 1159 are fixedly connected to both the left connecting pipe 1154 and the right connecting pipe 1155. The reinforcing plates 1159 are arranged around the end of the front bumper connecting pipe 1153 and form a connecting space 106. At least a part of the front bumper connecting pipe 1153 is located in the connecting space 106 and is connected to the reinforcing plate 1159. The front bumper connecting pipe 1153 is connected to the left connecting pipe 1154 and the right connecting pipe 1155 through the reinforcing plate 1159. Through the above arrangement, the reinforcing plate 1159 has a strong limiting effect, which can prevent the front bumper connecting pipe 1153 from shaking after being connected to the reinforcing plate 1159, thereby improving the connection strength between the front bumper connecting pipe 1153, the left connecting pipe 1154 and the right connecting pipe 1155, and further beneficial to improving the structural strength of the vehicle frame 11. In addition, the surface area of the reinforcing plate 1159 is relatively large, so as to carry body components such as the body covering 16, which is beneficial to improving the structural stability of the all-terrain vehicle 100.

[0043] In this embodiment, the reinforcing plate 1159 includes a front reinforcing plate 1156, a rear reinforcing plate 1157 and an upper reinforcing plate 1158. The front reinforcing plate 1156 and the rear reinforcing plate 1157 are located on both sides of the front bumper connecting pipe 1153 along the length direction of the all-terrain vehicle 100, and the front bumper connecting pipe 1153 is connected to the front reinforcing plate 1156 and the rear reinforcing plate 1157; the upper reinforcing plate 1158 is basically located above the front reinforcing plate 1156, the rear reinforcing plate 1157 and the upper reinforcing plate 1158, and the upper reinforcing plate 1158 is connected to the front reinforcing plate 1156 and the rear reinforcing plate 1157. Through the above settings, the connection strength of the front reinforcing plate 1156, the rear reinforcing plate 1157 and the upper reinforcing plate 1158 can be improved, so that the front bumper connecting pipe 1153 can be stably connected to the left connecting pipe 1154 and the right connecting pipe 1155, thereby improving the structural stability of the upper connecting frame 115, facilitating better support of body components such as the upper ceiling 165, and further improving the structural stability of the all-terrain vehicle 100.

[0044] As an implementation manner, both ends of the front bumper connecting pipe 1153 are provided with a first connection hole 1153b and a second connection hole 1153c, and the first connection hole 1153b and the second connection hole 1153c are distributed along the axial direction of the front bumper connecting pipe 1153. Specifically, the front reinforcing plate 1156 and the rear reinforcing plate 1157 are both provided with a third connection hole 1156a corresponding to the first connection hole 1153b, and the front reinforcing plate 1156 and the rear reinforcing plate 1157 are both provided with a fourth connection hole 1156b corresponding to the second connection hole 1153c. The first connection hole 1153b and the third connection hole 1156a are connected by fasteners, and the second connection hole 1153c and the fourth connection hole 1156b are also connected by fasteners, so that the front bumper connecting pipe 1153 is connected to the front reinforcing plate 1156 and the rear reinforcing plate 1157. Through the above settings, the front bumper connecting pipe 1153 can be connected to the front reinforcing plate 1156 and the rear reinforcing plate 1157 by multiple fasteners, which is beneficial to improving the connection strength of the front bumper connecting pipe 1153, the front reinforcing plate 1156 and the rear reinforcing plate 1157. It should be noted that bushings 1153d are provided in both the first connection hole 1153b and the second connection hole 1153c, and the fasteners pass through the bushings 1153d and then are connected to the front reinforcing plate 1156 and the rear reinforcing plate 1157. The bushings 1153d can improve the structural strength of the front bumper connecting pipe 1153, and thus are also beneficial to improving the connection stability of the front bumper connecting pipe 1153, the front reinforcing plate 1156 and the rear reinforcing plate 1157. It should be noted that the front bumper connecting pipe 1153 can be detached from the left connecting pipe 1154 and the right connecting pipe 1155, which facilitates the convenience of the all-terrain vehicle 100 during transportation.

[0045] As an implementation, the upper reinforcement plate 1158 is simultaneously connected to the front reinforcement plate 1156 and the rear reinforcement plate 1157. One end of the upper reinforcement plate 1158 away from the rear reinforcement plate 1157 extends at least partially towards the lower side of the all-terrain vehicle 100 to form a reinforcement portion 1158a. When observed along the length direction of the all-terrain vehicle 100, the reinforcement portion 1158a at least partially overlaps with the front reinforcement plate 1156 and the rear reinforcement plate 1157. Through the above arrangement, the structures of the front reinforcement plate 1156, the rear reinforcement plate 1157, and the upper reinforcement plate 1158 can be made more compact, which is beneficial to improving the structural compactness of the front reinforcement plate 1156, the rear reinforcement plate 1157, and the upper reinforcement plate 1158, and further beneficial to improving the space utilization rate of the all-terrain vehicle 100.

[0046] As an implementation, one end of the front reinforcement plate 1156 away from the rear reinforcement plate 1157 is arranged close to the reinforcement portion 1158a. A connecting portion 1156c is provided on the front reinforcement plate 1156. The connecting portion 1156c is located between the front reinforcement plate 1156 and the reinforcement portion 1158a and is fixedly connected to the front reinforcement plate 1156. The fastener passes through the bushing 1153d and is detachably connected to the connecting portion 1156c. Through the above arrangement, the connecting portion 1156c is arranged in the narrow space between the reinforcement portion 1158a and the front reinforcement plate 1156, which is beneficial to improving the structural compactness of the connecting portion 1156c, the reinforcement portion 1158a, and the front reinforcement plate 1156. At the same time, it is beneficial to the assembly speed of the fastener and the connecting portion 1156c, and further beneficial to improving the assembly efficiency of the all-terrain vehicle 100.

[0047] As an implementation, both the left connecting pipe 1154 and the right connecting pipe 1155 include a longitudinal bracket 1154a extending substantially along the front-rear direction of the all-terrain vehicle 100 and a column bracket 1154b distributed along the height direction of the all-terrain vehicle 100. The front end of the longitudinal bracket 1154a and the lower end of the column bracket 1154b are both connected to the lower support frame 116, and the rear end of the longitudinal bracket 1154a and the upper end of the column bracket 1154b are both connected. Further, a front-side mounting hole 1154c extending substantially along the height direction of the all-terrain vehicle 100 is provided at the front end of the longitudinal bracket 1154a, and a rear-side mounting hole 1154d extending substantially along the width direction of the all-terrain vehicle 100 is provided at the rear end of the longitudinal bracket 1154a. The axis of the front-side mounting hole 1154c is perpendicularly arranged to the axis of the rear-side mounting hole 1154d. Through the above arrangement, the connection strength between the longitudinal bracket 1154a and the column bracket 1154b can be improved, thereby avoiding deformation of the longitudinal bracket 1154a and the column bracket 1154b, and further beneficial to improving the structural stability of the all-terrain vehicle 100.

[0048] As Figure 5As shown, as an implementation, the upper end of the column bracket 1154b is provided with an upper mounting hole 1155a, and the lower end of the column bracket 1154b is provided with a lower mounting hole 1155b. The axes of the upper mounting hole 1155a and the lower mounting hole 1155b extend substantially along the width direction of the all-terrain vehicle 100. Specifically, the upper connecting frame 115 further includes a rear bumper connecting pipe 1151. The rear bumper connecting pipe 1151 extends along the width direction of the all-terrain vehicle 100 and is connected to the upper side of the column bracket 1154b. The upper mounting hole 1155a and the rear mounting hole 1154d are arranged near both ends of the rear bumper connecting pipe 1151. Through the above settings, the disassembly efficiency or the installation efficiency of the column bracket 1154b, the rear bumper connecting pipe 1151 and the longitudinal bracket 1154a can be improved, which is beneficial to improving the assembly efficiency of the all-terrain vehicle 100.

[0049] As Figure 1 and Figure 7 As shown, as an implementation, both the suspension system 14 and the winch device 25 are at least partially connected to the integrated frame 118. Among them, the integrated frame 118 includes a left rocker arm bracket 1183, a right rocker arm bracket 1184 and a winch mounting plate 1185. The left rocker arm bracket 1183 and the right rocker arm bracket 1184 are distributed along the width direction of the all-terrain vehicle 100 and are connected by the winch mounting plate 1185. The winch mounting plate 1185 is at least partially located above the left rocker arm bracket 1183 and the right rocker arm bracket 1184. The winch device 25 is located above the winch mounting plate 1185 and is fixedly connected to the winch mounting plate 1185. Through the above settings, the connection strength between the left rocker arm bracket 1183, the right rocker arm bracket 1184 and the winch mounting plate 1185 can be improved, and thus the connection strength between the winch device 25 and the vehicle frame 11.

[0050] Specifically, a left rocker arm mounting plate 1183a is provided on the left rocker arm bracket 1183. The left rocker arm mounting plate 1183a is basically connected to the side of the left rocker arm bracket 1183 away from the right rocker arm bracket 1184. The suspension system 14 includes a left rocker arm rod 143. The left rocker arm rod 143 is rotatably connected to the left rocker arm mounting plate 1183a, so that the left rocker arm rod 143 is connected to the left rocker arm bracket 1183 through the left rocker arm mounting plate 1183a. A right rocker arm mounting plate 1184a is provided on the right rocker arm bracket 1184. The right rocker arm mounting plate 1184a is basically connected to the side of the right rocker arm bracket 1184 away from the left rocker arm bracket 1183.

The right rocker arm rod is rotatably connected to the right rocker arm mounting plate 1184a, so that the right rocker arm rod is connected to the right rocker arm bracket 1184 through the right rocker arm mounting plate 1184a. Through the above settings, the winch mounting plate 1185 can improve the connection strength between the left rocker arm bracket 1183 and the right rocker arm bracket 1184. At the same time, the left rocker arm bracket 1183 and the right rocker arm bracket 1184 can be connected to the integrated frame 118. Moreover, the left rocker arm bracket 1183, the right rocker arm bracket 1184 and the integrated frame 118 occupy a small space, which is beneficial to improving the structural compactness of the left rocker arm bracket 1183, the right rocker arm bracket 1184 and the integrated frame 118, and improving the connection strength between the left rocker arm bracket 1183 and the right rocker arm bracket 1184 through the left rocker arm mounting plate 1183a and the right rocker arm mounting plate 1184a.

[0051] As an implementation, at least part of the winch mounting plate 1185 extends toward the side of the left rocker arm bracket 1183 away from the right rocker arm bracket 1184 to form a left end strengthening portion 1185a. The upper end of the left rocker arm mounting plate 1183a is connected to the left end strengthening portion 1185a, so that the left end strengthening portion 1185a and the left rocker arm mounting plate 1183a are simultaneously connected to the left rocker arm bracket 1183. Similarly, at least part of the winch mounting plate 1185 extends toward the side of the right rocker arm bracket 1184 away from the left rocker arm bracket 1183 to form a right end strengthening portion 1185b. The upper end of the right rocker arm mounting plate 1184a is connected to the right end strengthening portion 1185b, so that the right end strengthening portion 1185b and the right rocker arm mounting plate 1184a are simultaneously connected to the right rocker arm bracket 1184. Through the above settings, both ends of the winch mounting plate 1185 are connected to the left rocker arm mounting plate 1183a and the right rocker arm mounting plate 1184a, which is beneficial to improving the connection strength among the winch mounting plate 1185, the left rocker arm mounting plate 1183a and the right rocker arm mounting plate 1184a, and further improving the connection stability between the winch mounting plate 1185 and the integrated frame 118.

[0052] It should be noted that both the left end reinforcement part 1185a and the right end reinforcement part 1185b are in the form of sheet bodies. Along the width direction of the all-terrain vehicle 100, the left end reinforcement part 1185a and the right end reinforcement part 1185b are respectively located on both sides of the winch device 25. Specifically, when observing along the length direction of the all-terrain vehicle 100, the winch mounting plate 1185 is arranged around the left rocker arm bracket 1185 and the right rocker arm bracket 1184. Through the above arrangement, the contact area and connection area between the winch mounting plate 1185 and the left rocker arm bracket 1183 are increased, and the contact area and connection area between the winch mounting plate 1185 and the right rocker arm bracket 1184 are also increased, thereby improving the connection strength of the winch mounting plate 1185, the left rocker arm bracket 1183 and the right rocker arm bracket 1184, and further improving the structural strength of the integrated frame 118.

[0053] As an implementation manner, the left rocker arm bracket 1183 includes a left rocker arm mounting pipe 1183b extending along the length direction of the all-terrain vehicle 100, and the right rocker arm bracket 1184 includes a right rocker arm mounting pipe 1184b extending along the length direction of the all-terrain vehicle 100. When observing along the length direction of the all-terrain vehicle 100, the winch mounting plate 1185 is at least partially arranged around the left rocker arm mounting pipe 1183b and the right rocker arm mounting pipe 1184b. Specifically, when observing along the height direction of the all-terrain vehicle 100, the winch mounting plate 1185 at least partially overlaps with the left rocker arm mounting pipe 1183b and the right rocker arm mounting pipe 1184b. Through the above arrangement, the contact surfaces of the winch mounting plate 1185, the left rocker arm mounting pipe 1183b and the right rocker arm mounting pipe 1184b can be increased, which is beneficial to improving the connection strength of the winch mounting plate 1185, the left rocker arm mounting pipe 1183b and the right rocker arm mounting pipe 1184b.

[0054] As an implementation manner, radiator brackets 1186 are provided on both the left rocker arm mounting pipe 1183b and the right rocker arm mounting pipe 1184b. The radiator brackets 1186 are located behind the winch mounting plate 1185, and the winch mounting plate 1185 is arranged close to the radiator brackets 1186. Specifically, the integrated frame 118 further includes a winch connecting pipe 1187 extending along the width direction of the all-terrain vehicle 100. The winch connecting pipe 1187 is connected to the left rocker arm mounting pipe 1183 and the right rocker arm mounting pipe 1184. The winch mounting plate 1185 is connected behind the winch connecting pipe 1187. The front side of the winch device 25 is connected to the winch connecting pipe 1187 through fasteners. More specifically, the winch bracket 119 is located below the winch mounting plate 1185. Through the above arrangement, the structures of the radiator brackets 1186, the winch mounting plate 1185, the winch connecting pipe 1187 and the winch bracket 119 can be made more compact, which is beneficial to improving the structural compactness of the vehicle frame 11, and further enables the winch device 25 to be stably connected to the winch mounting plate 1185.

[0055] As Figure 5As shown, as an implementation manner, the vehicle frame 11 further includes a steering motor frame 11c and a steering reinforcement pipe 11d, and the steering reinforcement pipe 11d is connected to the steering motor frame 11c. Specifically, the power system 13 includes a power steering motor (not shown in the figure), the power steering motor is connected to the steering motor frame 11c, and the motor controller 19c is integrated on the steering reinforcement pipe 11d. Through the above settings, the steering reinforcement pipe 11d can improve the structural stability of the steering motor frame 11c. Similarly, the structures of the power steering motor 135 and the motor controller 19c are also more stable, which is beneficial to improving the structural stability of the all-terrain vehicle 100.

[0056] As an implementation manner, the seat system 17 is connected to the vehicle frame 11 and is located within the driving space 102. Specifically, the vehicle frame 11 includes a vehicle body support frame 11e and a saddle support frame 11f. The saddle support frame 11f is detachably connected to the vehicle body support frame 11e. The seat system 17 is located above the saddle support frame 11f and is detachably connected to the saddle support frame 11f and the vehicle body support frame 11c. Among them, the saddle support frame 11f includes a transverse connecting pipe 111f, a longitudinal connecting pipe 112f, and a height support pipe 113f. The front end of the longitudinal connecting pipe 112f and the upper end of the height support pipe 113f are both connected to the transverse connecting pipe 111f. The rear end of the longitudinal connecting pipe 112f and the lower end of the height support pipe 113f are both connected to the vehicle body support frame 11e. Through the above settings, when the saddle support frame 11f needs to be disassembled or installed, the separation from the vehicle body support frame 11e can be achieved by disassembling the rear end of the longitudinal connecting pipe 112f and the lower end of the height support pipe 113f, which is beneficial to improving the assembly efficiency of the saddle support frame 11f. In addition, connecting the front end of the longitudinal connecting pipe 112f and the upper end of the height support pipe 113f to the transverse connecting pipe 111f can endow the longitudinal connecting pipe 112f and the height support pipe 113f with a certain deformation ability, avoiding improper assembly caused by process errors, and thus being beneficial to improving the assembly efficiency of the saddle support frame 11f.

[0057] Further, the transverse connecting pipe 111f extends along the width direction of the all-terrain vehicle 100, the longitudinal connecting pipe 112f extends along the front-rear direction of the all-terrain vehicle 100 and is distributed along the width direction of the all-terrain vehicle 100, and the height support pipe 113f extends along the height direction of the all-terrain vehicle 100 and is distributed along the width direction of the all-terrain vehicle 100. Through the above settings, the saddle bracket 11f includes multiple transverse connecting pipes 111f and multiple longitudinal connecting pipes 112f, so that the structure of the saddle bracket 11f is more stable, which is conducive to improving the structural strength of the saddle bracket 11f. It should be noted that when the transverse connecting pipe 111f, the longitudinal connecting pipe 112f and the height support pipe 113f are set as circular pipes, the axes of the transverse connecting pipe 111f, the longitudinal connecting pipe 112f and the height support pipe 113f are perpendicular to each other, so that the structures of the transverse connecting pipe 111f, the longitudinal connecting pipe 112f and the height support pipe 113f are more compact, which is conducive to improving the structural compactness of the transverse connecting pipe 111f, the longitudinal connecting pipe 112f and the height support pipe 113f.

[0058] As an implementation manner, the vehicle body support frame 11e includes a saddle connecting pipe 111e extending along the width direction of the all-terrain vehicle 100. The saddle connecting pipe 111e is located behind the transverse connecting pipe 111f. The rear end of the longitudinal connecting pipe 112f is detachably connected to the saddle connecting pipe 111e. At least part of the seat system 17 is located above the saddle connecting pipe 111e and is connected to the saddle connecting pipe 111e. Specifically, since the width of the saddle bracket 11f is relatively large and the seat system 17 occupies a large space, the saddle connecting pipe 111e is provided behind the saddle bracket 11f, which can improve the structural strength of the frame 11 body. Through the above settings, it is convenient for the assembly of the saddle bracket 11f and is also conducive to improving the space utilization rate of the all-terrain vehicle 100.

[0059] As Figure 8 shown, in the present embodiment, a saddle connecting portion 112e is provided on the saddle connecting pipe 111e, a longitudinal connecting portion 114f is provided at the rear end of the longitudinal connecting pipe 112f, at least part of the longitudinal connecting portion 114f is clamped in the saddle connecting portion 112e, and the saddle connecting portion 112e and the longitudinal connecting portion 114f are detachably connected by fasteners. Through the above settings, the longitudinal connecting pipe 112f can be first clamped in the saddle connecting portion 112e to limit the displacement of the longitudinal connecting pipe 112f along the width direction of the all-terrain vehicle 100, and then reinforced by fasteners, which is conducive to improving the assembly speed and connection stability between the longitudinal connecting pipe 112f and the saddle connecting portion 112e.

[0060] As an implementation, the vehicle body support frame 11e further includes a bottom support frame 113e located below the saddle support frame 11f. The lower end of the height support pipe 113f abuts against the bottom support frame 113e, so that the height support pipe 113f is detachably connected to the bottom support frame 113e. Specifically, a plurality of first through holes 114e are provided on the bottom support frame 113e, and the first through holes 114e are distributed along the width direction of the all-terrain vehicle 100. The lower end of the height support pipe 113f is provided with second through holes 115f corresponding to the through holes, and the first through holes 114e and the second through holes 115f are detachably connected by fasteners. With the above arrangement, the height support pipe 113f and the bottom support frame 113e can be stably connected, which is beneficial to improving the connection stability between the height support pipe 113f and the bottom support frame 113e. It should be noted that the first through holes 114e and / or the second through holes 115f are arranged as waist-shaped holes to facilitate the adjustment of the positions of the height support pipe 113f and the bottom support frame 113e, which is beneficial to improving the assembly efficiency of the height support pipe 113f and the bottom support frame 113e.

[0061] As an implementation, an installation space 107 is formed after the vehicle body support frame 11e and the saddle support frame 11f are connected. The all-terrain vehicle 100 further includes an energy system 34, and the energy system 34 is located in the installation space 107 and is connected to the bottom support frame 113e. Specifically, the energy system 34 can be a device such as a power battery 24 or a storage battery 35 that provides energy for the electrical system 19. With the above arrangement, the connection stability between the energy system 34 and the vehicle frame 11 can be improved. At the same time, since the disassembly method of the saddle support frame 11f and the vehicle body support frame 11e is simple, it is convenient for the installation of the energy system 34 and the vehicle frame 11, which is beneficial to improving the assembly efficiency of the energy system 34 and the vehicle frame 11.

[0062] As an implementation, the seat system 17 includes a seat cushion 178, and at least part of the seat cushion 178 is located above the saddle support frame 11f and is detachably connected to the saddle support frame 11f. Specifically, a front positioning portion 116f is provided on the transverse connecting pipe 111f, and a rear positioning portion 115e is provided on the saddle connecting pipe 111e. The seat cushion 178 can be connected to the front positioning portion 116f and the rear positioning portion 115e. With the above arrangement, the seat cushion 178 can be connected to the front positioning portion 116f and the rear positioning portion 115e by connection methods such as fasteners, so that the seat cushion 178 can be stably connected to the saddle support frame 11f, which is beneficial to improving the connection stability between the seat cushion 178 and the saddle support frame 11f. In addition, the seat cushion 178 can also be detached from the vehicle body support frame 11e together with the saddle support frame 11f, which is beneficial to improving the disassembly efficiency of the seat cushion 178 and the saddle support frame 11f.

[0063] As Figure 9 and Figure 10As shown, as an implementation, the vehicle frame 11 includes a transmission support bracket 11g extending along the length direction of the all-terrain vehicle 100 and a transmission mounting plate 11k extending along the width direction of the all-terrain vehicle 100. The transmission support brackets 11g are distributed along the width direction of the all-terrain vehicle 100. The transmission mounting plate 11k is located between the transmission support brackets 11g and is detachably connected to the transmission support brackets 11g. The transmission support brackets 11g and the transmission mounting plate 11k are basically located at the bottom of the vehicle frame 11. Through the above settings, the transmission mounting plate 11k can be stably connected to the transmission support brackets 11g, which is beneficial to improving the connection stability between the transmission support brackets 11g and the transmission mounting plate 11k. Among them, the transmission system 31 includes a transmission shaft 311. The transmission shaft 311 can be installed from below the transmission support bracket 11g to above the transmission support bracket 11g. The transmission shaft 311 is at least partially located above the transmission mounting plate 11k and is connected to the transmission mounting plate 11k. Specifically, the transmission support bracket 11g includes a left transmission bracket 11h and a right transmission bracket 11j. When observed along the height direction of the all-terrain vehicle 100, the transmission shaft 223 is basically located between the left transmission bracket 11h and the right transmission bracket 11j. The distance between the left transmission bracket 11h and the right transmission bracket 11j is greater than the length of the transmission shaft 311 along the width direction of the all-terrain vehicle 100. Through the above settings, the transmission shaft 311 is arranged between the left transmission bracket 11h and the right transmission bracket 11j. When the transmission shaft 311 needs to be installed, the transmission shaft 311 can be installed from the lower side of the left transmission bracket 11h and the right transmission bracket 11j to the upper side of the left transmission bracket 11h and the right transmission bracket 11j, thus avoiding disassembling too many vehicle body parts, which is beneficial to improving the assembly efficiency of the transmission shaft 311. In addition, the transmission mounting plate 11k can provide better support for the transmission shaft 311. At the same time, the disassembly method of the transmission mounting plate 11k and the transmission support bracket 11g is simple, so that the transmission shaft 311 can be disassembled from the transmission support bracket 11g synchronously with the transmission mounting plate 11k, reducing the disassembly steps, which is also beneficial to improving the disassembly efficiency of the all-terrain vehicle 100.

[0064] As an implementation, the vehicle frame 11 further includes a transmission limiting plate 11m. The transmission limiting plate 11m at least partially surrounds the transmission shaft 311. The transmission shaft 311 is connected to the transmission limiting plate 11m, and the transmission limiting plate 11m is detachably connected to the transmission mounting plate 11k. Specifically, at least a part of the transmission limiting plate 11m is located on the upper side of the transmission shaft 311, and the transmission limiting plate 11m and the transmission mounting plate 11k are detachably connected by fasteners. Specifically, the transmission mounting plate 11k is provided with transmission mounting holes 111k extending in the height direction of the all-terrain vehicle 100 and distributed in the width direction of the all-terrain vehicle 100. The transmission limiting plate 11m is provided with limiting mounting holes 111m corresponding to the transmission mounting holes 111k, and the transmission mounting holes 111k and the limiting mounting holes 111m are detachably connected by fasteners. Through the above settings, the connection strength between the transmission limiting plate 11m and the transmission mounting plate 11k can be improved, so as to facilitate the stable installation of the transmission shaft 311 between the transmission limiting plate 11m and the transmission mounting plate 11k, thereby being beneficial to improving the stability of the transmission shaft 311.

[0065] As an implementation, both ends of the transmission mounting plate 11k are provided with mounting plate support parts 112k, and the mounting plate support parts 112k abut against the left transmission frame 11h and the right transmission frame 11j. Specifically, the mounting plate support parts 112k can enhance the strength of the transmission mounting plate 11k, thereby being beneficial to improving the structural stability of the transmission mounting plate 11k, the left transmission frame 11h and the right transmission frame 11j, and further improving the stability of the transmission shaft 311. More specifically, the mounting plate support parts 112k are provided with mounting plate fixing holes 113k extending in the width direction of the all-terrain vehicle 100 and distributed in the length direction of the all-terrain vehicle 100. Both the left transmission frame 11h and the right transmission frame 11j are provided with transmission fixing holes 111j corresponding to the mounting plate fixing holes 113k, and the mounting plate fixing holes 113k and the transmission fixing holes 111j are detachably connected by fasteners. Through the above settings, the transmission mounting plate 11k can be detached from the left transmission frame 11h and the right transmission frame 11j, which is beneficial to improving the assembly efficiency of the transmission mounting plate 11k, the left transmission frame 11h and the right transmission frame 11j.

[0066] In addition, a reinforcing bushing 112j is arranged in the transmission fixing hole 111j. The reinforcing bushing 112j is fixedly connected to the transmission fixing hole 111j, and the fastener passes through the reinforcing bushing 112j and is connected to the mounting plate support part 112k. Specifically, the reinforcing bushing 112j can enhance the strength of the left transmission frame 11h and the right transmission frame 11j. At the same time, the transmission mounting plate 11k is provided with a protection and strengthening part 114k, and the protection and strengthening part 114k is arranged at the edge of the transmission mounting plate 11k, thereby further improving the structural stability of the transmission mounting plate 11k, the left transmission frame 11h and the right transmission frame 11j.

[0067] As an implementation manner, when observing along the longitudinal direction of the all-terrain vehicle 100, the axis of the transmission mounting hole 111k is perpendicularly arranged to the axis of the mounting plate fixing hole 113k. Through the above arrangement, the structures of the transmission mounting hole 111k and the mounting plate fixing hole 113k can be made more compact, and thus it is beneficial to improve the structural compactness of the transmission mounting plate 11k, the left transmission frame 11h and the right transmission frame 11j.

[0068] As an implementation manner, the body covering member 16 further includes a lower guard plate (not shown in the figure), and the lower guard plate is located below the left transmission frame 11h and the right transmission frame 11j and is connected to the transmission mounting plate 11k. Specifically, the lower guard plate can prevent the lower part of the transmission shaft 311 from being exposed outside to cause waterlogging, so as to prevent the service life of the transmission shaft 311 from being reduced. Through the above arrangement, the service life of the transmission shaft 311 can be improved, and at the same time, the lower guard plate can also improve the sealing performance of the all-terrain vehicle 100.

[0069] Such as Figure 11 And Figure 12As shown, as one implementation, the all-terrain vehicle 100 includes a cargo box system 21, which is at least partially connected to the vehicle frame 11. Specifically, the vehicle frame 11 includes a rear support frame 11n located at the rear of the vehicle frame 11 and a rotating bracket 11p. The rotating bracket 11p is at least partially located above the rear support frame 11n and is rotatably connected to the rear support frame 11n. More specifically, the all-terrain vehicle 100 includes a hydraulic device 36 located below the cargo box system 21. The hydraulic device 36 is supported by the vehicle frame 11 and electrically connected to the electrical system 19. The hydraulic device 36 is respectively connected to the rear support frame 11n and the rotating bracket 11p. Specifically, one end of the hydraulic device 36 is rotatably connected to the rotating bracket 11p, and the other end of the hydraulic device 36 is rotatably connected to the rear support frame 11n. The rotating bracket 11p has a first state and a second state, and the hydraulic device 36 can drive the rotating bracket 11p to switch between the first and second states. Specifically, when the rotating bracket 11p is in the first state, the rotating bracket 11p is arranged parallel to the rear support frame 11n. When the rotating bracket 11p is in the second state, the rotating bracket 11p forms an angle with the rear support frame 11n. Through the above arrangement, the rotating bracket 11p can be rotatably connected to the rear support frame 11n via the hydraulic device 36, thereby facilitating an increase in the rotation speed of the rotating bracket 11p and the rear support frame 11n, thereby increasing the switching speed between the first state and the second state, and further facilitating improved operability of the rotating bracket 11p and the rear support frame 11n. It can be understood that the cargo box system 21 includes a rear box 213, which is located above the rotating bracket 11p and is fixedly connected to the rear box 213. The rear box 213 can rotate with the rotating bracket 11p. The rear box 213 is used to carry cargo. When the rear box 213 is loading or unloading, the rotating bracket 11p can be driven by the hydraulic device 36 so that the rear box 213 can rotate with the rotating bracket 11p, which is beneficial to improve the working efficiency of the rear box 213 during the loading or unloading process.

[0070] Exemplarily, the hydraulic device 36 includes a driving member 361 and a telescopic member 362. The driving member 361 is in transmission connection with the telescopic member 362, and the driving member 361 can control the length of the telescopic member 362. Specifically, the telescopic member 362 has telescopic capabilities. The ends of the telescopic member 362 are connected to the rotating bracket 11p and the rear support frame 11n, thereby enabling the rotating bracket 11p and the rear support frame 11n to achieve a rotational connection through the telescopic member 362. Furthermore, the driving member 361 drives the rotation of the rotating bracket 11p and the rear support frame 11n by driving the telescopic member 362. Through the above arrangement, the driving member 361 and the telescopic member 362 are separated, which can reduce the volume of the hydraulic device 36, thereby preventing the hydraulic device 36 from occupying a large space, thereby facilitating improved space utilization of the all-terrain vehicle 100.

[0071] As an implementation, a drive control unit 3611 is further provided on the drive member 361. The drive control unit 3611 is electrically connected to the electrical system 19, and the electrical system 19 controls the operation of the drive control unit 3611. Specifically, the electrical system 19 is connected to the drive control unit 3611 through a wiring harness. A motor is provided inside the drive member 361, and the drive control unit 3611 can control the rotation of the motor, thereby realizing the control of the operation of the telescopic member 362.

[0072] As an implementation, a support fixing part 111n is provided on the rear support frame 11n. The telescopic member 362 includes a first rotating part 3621, and the first rotating part 3621 is rotatably connected to the support fixing part 111n. Further, a bracket fixing part 111p is provided on the rotating bracket 11p. One end of the telescopic member 362 away from the telescopic support fixing part 111n is provided with a second rotating part 3622, and the second rotating part 3622 is rotatably connected to the bracket fixing part 111p. Through the above settings, the first rotating part 3621 and the second rotating part 3622 can rotate simultaneously, so as to control the distance between the support fixing part 111n and the bracket fixing part 111p, and further facilitate improving the rotation efficiency of the support fixing part 111n and the bracket fixing part 111p.

[0073] It can be understood that a rear end fixing part 112n distributed in the width direction of the all-terrain vehicle 100 is provided at the rear end of the rear support frame 11n. A rear end rotating part 112p cooperating with the rear end fixing part 112n is provided on the rotating bracket 11p, and the rear end rotating part 112p is rotatably connected to the rear end fixing part 112n, which is beneficial to improving the rotation speed of the rear support frame 11n and the rotating bracket 11p.

[0074] As an implementation, the all-terrain vehicle 100 further includes a vehicle locking device 38, which is supported by the vehicle frame 11 and transmission-connected to the hydraulic device 36. The cargo box system 21 is connected to the rotating bracket 11p and supported by the rear support frame 11n. The rear support frame 11n and the rotating bracket 11p are locked via the vehicle locking device 38. Specifically, the vehicle locking device 38 further includes a pusher 381 and a hydraulic pipe 382 in communication with the hydraulic device 36. The driving member 361 is in communication with the pusher 381 via the hydraulic pipe 382. The driving member 361 can control the length of the pusher 381. The hydraulic device 36 can open or close the vehicle locking device 38 by adjusting the length of the pusher 381. Specifically, the pushing member 381 has a telescopic function, the hydraulic tube 382 is a hollow tube structure, and hydraulic oil is provided in the driving member 361 and the hydraulic tube 382. The driving member 361 can transport the hydraulic oil to the pushing member 381 during operation, thereby increasing the length of the pushing member 381. Similarly, the driving member 361 can also transport the hydraulic oil from the pushing member 381 back to the driving member 361 and the hydraulic tube 382 during operation, thereby reducing the length of the pushing member 381. Through the above arrangement, the locking device 38 can restrict the rotation of the rear support frame 11n and the rotating bracket 11p. The driving member 361 opens or closes the locking device 38 by controlling the length of the pushing member 381. When the locking device 38 is closed, the rear support frame 11n is fixedly connected to the rotating bracket 11p, thereby improving the stability of the connection between the rear support frame 11n and the rotating bracket 11p. When the locking device 38 is opened, the rear support frame 11n and the rotating bracket 11p are rotationally connected, thereby improving the rotational flexibility of the rear support frame 11n and the rotating bracket 11p. In addition, the driving member 361 can simultaneously drive the telescopic member 362 and the pushing member 381 to operate, thereby enabling the hydraulic device 36 and the locking device 38 to operate synchronously, thereby further improving the intelligence level of the all-terrain vehicle 100.

[0075] like Figure 13 As shown, as an implementation, the vehicle locking device 38 includes a latch 383 and a positioning member 384. The pusher 381 can drive the latch 383 to engage or disengage with the positioning member 384. When the latch 383 is engaged with the positioning member 384, the rotating bracket 11p is in a first state. When the latch 383 is disengaged from the positioning member 384, the rotating bracket 11p is in a second state. Specifically, the latch 383 is disposed on the rotating bracket 11p, and the positioning member 384 is disposed on the rear support frame 11n. This arrangement simplifies the connection between the latch 383 and the positioning member 384, thereby facilitating faster assembly of the latch 383 and the positioning member 384, and thereby improving the operating efficiency of the vehicle locking device 38.

[0076] As an implementation, the hydraulic device 36 is drivingly connected to the vehicle lock device 38. The rear support frame 11n and the rotating bracket 11p are rotationally connected through the hydraulic device 36, and the rear support frame 11n and the rotating bracket 11p are locked through the vehicle lock device 38. Specifically, the pushing member 381 can push the rotation of the buckling member 383. Among them, the vehicle lock device 38 further includes a buckling shaft 385 and a buckling return spring 386. Both the buckling member 383 and the buckling return spring 386 are sleeved on the buckling shaft 385. The buckling return spring 386 is at least partially clamped on the buckling member 383. The buckling member 383 includes an open state and a closed state. The pushing member 381 pushes the buckling member 383 to be in the open state, and the buckling return spring 386 pushes the buckling member 383 to be in the closed state. Through the above settings, under the action of the buckling shaft 385 and the buckling return spring 386, the buckling member 383 can be clamped or separated from the positioning member 384, which is beneficial to realize the rotation or locking of the rotating bracket 11p, and further beneficial to controlling the lifting of the rear trunk 213, and at the same time beneficial to improving the intelligent degree of the all-terrain vehicle 100.

[0077] Exemplarily, the vehicle lock device 38 further includes a support member 387 and a limiting shaft 388. Both the buckling shaft 385 and the limiting shaft 388 are fixedly connected to the support member 387. When the buckling member 383 is in the open state, the end of the buckling member 383 close to the pushing member 381 is separated from the limiting shaft 388. When the buckling member 383 is in the closed state, the end of the buckling member 383 close to the pushing member 381 is in contact with the limiting shaft 388. Through the above settings, the support member 387 and the limiting shaft 388 can be used to limit the rotation angle of the buckling member 383, avoiding the rotation angle of the buckling member 383 being too large and causing the pushing member 381 to receive the thrust of the buckling member 383 and reducing the service life, which is beneficial to improving the service life of the pushing member 381.

[0078] As an implementation, the positioning member 384 includes a positioning portion 3841. A limiting groove 113p is provided on the rotating bracket 11p. When the rotating bracket 11p is in the first state, at least part of the positioning portion 3841 is located in the limiting groove 113p, and at least part of the end of the buckling member 383 far from the pushing member 381 is located below the positioning portion 3841. Specifically, when the rotating bracket 11p is in the first state, the limiting groove 113p can limit the movement of the rotating bracket 11p along the length direction of the all-terrain vehicle 100, and the buckling member 383 can limit the movement of the rotating bracket 11p along the height direction, which is beneficial to improving the connection stability between the rotating bracket 11p and the rear support frame 11n. In addition, a plurality of buffer structures are provided between the rotating bracket 11p and the rear support frame 11n, avoiding rigid contact between the rotating bracket 11p and the rear support frame 11n, and further beneficial to extending the service life of the rotating bracket 11p and the rear support frame 11n.

[0079] It should be understood that those of ordinary skill in the art can make improvements or modifications based on the above description, and all such improvements and modifications shall fall within the scope of protection of the appended claims of this application.
