[0026] 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 drawings in the embodiments of the present application.

[0027] As Figure 1 and Figure 2 shown, the present application provides an all-terrain vehicle 100, which includes a frame 11, a body cover 12, a running system 13, a suspension system 14, a power assembly 15, a transmission assembly 16, a fuel assembly 17, a seat assembly 19 and an electrical assembly 22.

[0028] In order to clearly illustrate the technical solution of the present application, the front, rear, left, right, up and down as Figure 1 shown are also defined. In the present application, the length direction of the frame 11 refers to the Figure 1 front-back direction inFigure 1 The left - right direction in [reference] and the height direction of the frame 11 refer to Figure 1 the up - down direction in [reference].

[0029] Among them, the frame 11 serves as the basic framework of the all - terrain vehicle 100 and is used to support the body cover 12, the running system 13, the suspension system 14, the power assembly 15, the transmission assembly 16, the fuel assembly 17, the seat assembly 19, and the electrical component 22. The body cover 12 is at least partially located on and connected to the frame 11 so that the body cover 12 can protect the components inside the all - terrain vehicle 100. The running system 13 is at least partially located below the frame 11, and the suspension system 14 connects the running system 13 to the frame 11. The power assembly 15 is in transmission connection with the running system 13. Specifically, the transmission assembly 16 transmits the power of the power assembly 15 to the running system 13. The fuel assembly 17 includes a fuel tank 171, and the fuel tank 171 is used to supply energy to the power assembly 15. Specifically, the fuel tank 171 is used to deliver fuel to the power assembly 15. The electrical component 22 is supported by the frame 11, or the electrical component 22 is supported by the body cover 12 or the frame 11. The electrical component 22 is used to display the driving data of the all - terrain vehicle 100, control the operation of the all - terrain vehicle, etc. The seat assembly 19 is supported by the frame 11, and the seat assembly 19 is used to support the driver and / or passengers.

[0030] As Figure 3 and Figure 4 shown, as an implementation manner, the all - terrain vehicle 100 includes a steering system 20. The steering system 20 includes a steering handle 201, a steering tube 202, and a mounting seat 203.

[0031] Among them, the mounting seat 203 is used to connect the steering tube 202 and the steering handle 201, and the mounting seat 203 is located above the steering tube 202. The mounting seat 203 includes a lower mounting wall 2031, and the lower mounting wall 2031 is provided with a first channel 2031a extending along the height direction of the frame 11. The mounting seat 203 further includes a left mounting wall 2032 and a right mounting wall 2035 opposite to each other along the width direction of the frame 11. The left mounting wall 2032 and / or the right mounting wall 2035 are provided with a second channel 2032a extending along the width direction of the frame 11. The first channel 2031a and the second channel 2032a are in communication, and both the first channel 2031a and the second channel 2032a are configured to allow a wire harness and / or a pipeline to pass through.

[0032] Such a configuration can facilitate the wiring harness and / or pipeline to be laid at the mounting seat 203, thereby avoiding the need to install additional components for wiring and / or pipeline at the mounting seat 203, which is conducive to simplifying the structure at the mounting seat 203, thereby helping to reduce the overall cost of the all-terrain vehicle 100. In addition, through the above configuration, the compactness of the structure of the wiring harness and / or pipeline at the mounting seat 203 can also be improved, thereby avoiding the wiring harness and / or pipeline being scattered and interfering with the driver's driving of the all-terrain vehicle 100, thereby helping to improve the driving safety of the all-terrain vehicle 100. In addition, it can also avoid the wiring harness and / or pipeline being scattered and causing the wiring harness and / or pipeline to be exposed and worn, thereby helping to improve the service life of the wiring harness and / or pipeline.

[0033] As an embodiment, the left mounting wall 2032 and / or the right mounting wall 2035 are both provided with a second channel 2032a extending in the width direction of the vehicle frame 11, and the two second channels 2032a are connected. With such a configuration, the wiring harness and / or pipelines arranged in the mounting seat 203 can be arranged from the two second channels 2032a to the two sides of the steering handle 201 in the width direction of the vehicle frame 11, thereby facilitating the installation seat 203 to arrange the wiring harness and / or pipelines conveniently.

[0034] like Figure 4 As shown, as an embodiment, the mounting seat 203 is surrounded by an installation space 2033 for accommodating a wire harness and / or a pipeline, and the first channel 2031a and the second channel 2032a are at least partially located in the accommodation space 2033. In this way, during the assembly process of the wire harness and / or the pipeline, the installation space 2033 can provide an accommodation space for the overlong wire harness and / or the pipeline, thereby avoiding the wire harness and / or the pipeline being too long to be accommodated and causing the wire harness and / or the pipeline to be scattered, thereby further improving the compactness and neatness of the structure of the wire harness and / or the pipeline at the mounting seat 203.

[0035] In addition, by at least partially recessing the mounting seat 203 to form the mounting space 2033 , the weight of the mounting seat 203 can be reduced, thereby making the steering system 20 more lightweight, and further facilitating the driver to drive the steering system 20 to control the steering of the all-terrain vehicle 100 .

[0036] In this embodiment, the steering system 20 further includes a protection plate 204 (see Figure 3 ), the protection plate 204 covers the installation space 2033 and is fixedly connected to the mounting seat 203. In this way, the protection plate 204 can limit the wiring harness and / or pipeline in the installation space 2033, thereby preventing the wiring harness and / or pipeline from being separated from the installation space 2033, thereby facilitating the layout stability of the wiring harness and / or pipeline in the mounting seat 203.

[0037] Secondly, the protection plate 204 can protect the wiring harness and / or pipeline in the installation space 2033. Along the length direction of the vehicle frame 11, the protection plate 204 is located in front of the installation space 2033. Thus, during the driving of the all-terrain vehicle 100, the protection plate 204 can shield the installation space 2033 to prevent flying stones and grit from wearing the wiring harness and / or pipeline, which is conducive to improving the service life of the wiring harness and / or pipeline.

[0038] As Figure 4 shown, as an implementation manner, the mounting seat 203 is provided with a weight-reducing hole 2034 that generally penetrates the mounting seat 203 along the length direction of the vehicle frame 11. With such a setting, the weight of the mounting seat 203 can be further reduced through the weight-reducing hole 2034, thereby further reducing the overall weight of the steering system 20 and realizing the light weight of the steering system 20.

[0039] Specifically, the weight-reducing hole 2034 is communicated with the installation space 2033. With such a setting, the weight-reducing hole 2034 can expand the volume of the installation space 2033, so that the installation space 2033 can accommodate more wiring harnesses and / or pipelines.

[0040] As an implementation manner, the second channel 2032a is configured to be able to reduce the weight of the mounting seat 203. Specifically, the ratio range of the height H3 of the second channel 2032a along the height direction of the vehicle frame 11 to the height H4 of the mounting seat 203 along the height direction of the vehicle frame 11 is 0.4 to 0.62. Specifically, the ratio range of the height H3 of the second channel 2032a along the height direction of the vehicle frame 11 to the height H4 of the mounting seat 203 along the height direction of the vehicle frame 11 is 0.45 to 0.57. More specifically, the ratio of the height H3 of the second channel 2032a along the height direction of the vehicle frame 11 to the height H4 of the mounting seat 203 along the height direction of the vehicle frame 11 is 0.51. With such a setting, by increasing the height H3 of the second channel 2032a along the height direction of the vehicle frame 11, the weight of the mounting seat 203 can be further reduced, which is conducive to the driver to control the steering system 20. Secondly, it can be avoided that the height H3 of the second channel 2032a along the height direction of the vehicle frame 11 is too large, resulting in the second channel 2032a being too large, so as to avoid reducing the structural strength of the mounting seat 203 due to the second channel 2032a being too large, which is conducive to reducing the overall counterweight of the mounting seat 203 on the premise of meeting the structural strength of the mounting seat 203. In addition, it can also be avoided that the height H3 of the second channel 2032a along the height direction of the vehicle frame 11 is too small, resulting in the weight of the mounting seat 203 being too large, which is conducive to realizing the light weight of the steering system 20.

[0041] As Figure 5As shown, as an implementation manner, the body covering 12 includes an instrument mounting cover 1204 for mounting an instrument. The instrument mounting cover 1204 is supported by the frame 11, and the mounting seat 203 is at least partially located within the instrument mounting cover 1204. With such a setting, the mounting seat 203 can be protected through the instrument mounting cover 1204, thereby avoiding abrasion and erosion of the mounting seat 203 by flying stones and gravel, which is beneficial for protecting the wiring harness and / or pipeline inside the mounting seat 203. In addition, it is also possible to avoid adding additional components for protecting the mounting seat 203 on the all-terrain vehicle 100, which is beneficial for simplifying the overall structure of the all-terrain vehicle 100 and thus reducing the overall cost of the all-terrain vehicle 100.

[0042] As Figure 5 and Figure 6 As shown, as an implementation manner, the steering system 20 includes a steering rocker arm 205, a steering ball joint 206, and a steering tie rod 207. Among them, the steering rocker arm 205 is connected to the steering tube 202, and the steering tie rod 207 is rotatably connected to the steering rocker arm 205 through the steering ball joint 206. Specifically, the steering rocker arm 205 includes a connecting portion 2051 and a rocker arm portion 2052. The connecting portion 2051 is connected to the steering tube 202, and the rocker arm portion 2052 is rotatably connected to the steering ball joint 206.

[0043] In some embodiments, the connecting portion 2051 and the rocker arm portion 2052 are integrally formed, which is beneficial for improving the connection stability between the steering tube 202 and the steering ball joint 206 through the steering rocker arm 205.

[0044] More specifically, as Figure 7 shown, a transverse plane 108 perpendicular to the length direction of the frame 11 and a longitudinal plane 109 perpendicular to the width direction of the frame 11 are defined. The steering ball joint 206 extends substantially along the direction of a preset straight line 10a. The positive projection of the preset straight line 10a on the transverse plane 108 is a first projection line, the positive projection of the preset straight line 10a on the longitudinal plane 109 is a second projection line, the positive projection of the axis of the steering tube 202 on the transverse plane 108 is an axis first axis projection, and the positive projection of the axis of the steering tube 202 on the longitudinal plane 109 is an axis second projection.

[0045] In the present application, one end of the steering tie rod 207 away from the steering ball joint 206 is connected to the running system 13. When the all-terrain vehicle 100 travels over rough terrain, the running system 13 will bounce according to the terrain. At this time, the running system 13 drives the steering ball joint 206 to swing through the steering tie rod 207.

[0046] In the present embodiment, the rocker arm portion 2052 is configured to be bendable such that the range of the acute angle β formed between the first projection line and the first-axis projection of the axis is 5° to 45°, and the range of the acute angle Ω formed between the second projection line and the second-axis projection of the axis is 5° to 45°. Specifically, the rocker arm portion 2052 is configured to be bendable such that the range of the acute angle β formed between the first projection line and the first-axis projection of the axis is 15° to 30°, and the range of the acute angle Ω formed between the second projection line and the second-axis projection of the axis is 15° to 30°. By setting it in this way, the steering ball pin 206 can be inclined by bending the rocker arm portion 2052, so that a larger swing stroke can be provided for the steering ball pin 206, thereby avoiding the situation that the swing stroke of the steering ball pin 206 is too small due to the steering ball pin 206 being arranged along the height direction of the vehicle frame 11, and further avoiding the collision and wear of the steering ball pin 206 during the swing process due to the too small swing stroke of the steering ball pin 206, which is beneficial to improving the service life of the steering ball pin 206. Secondly, by increasing the swing stroke of the steering ball pin 206, it is beneficial for the running system 13 to have a greater degree of jounce, and further beneficial for the all-terrain vehicle 100 to drive over more rugged terrains, which is beneficial to improving the passability of the all-terrain vehicle 100.

[0047] It should be noted that the directions in which the steering ball pin 206 swings are defined as the first direction and the second direction, and the first direction and the second direction are opposite. Among them, the angle at which the steering ball pin 206 swings in the first direction is defined as 30°, and the angle at which the steering ball pin 206 swings in the second direction is defined as 30°. If the range of the acute angle β is not set within the above angle range, the installed steering ball pin 206 will deflect in the first direction or the second direction. Taking the example that the installed steering ball pin 206 deflects 16° in the first direction and the steering ball pin 206 needs to be able to rotate 14° in the first direction or the second direction, during the working process of the steering ball pin 206, the actual angular orientation of its rotation in the second direction is between 16° and 30°. At this time, the steering ball pin 206 will rotate within its limit rotation angle, which will cause wear of the steering ball pin 206 and further reduce the service life of the steering ball pin 206. Secondly, if the angle at which the steering ball pin 206 needs to be able to rotate in the first direction or the second direction is greater than 14°, the installed steering ball pin 206 cannot meet the requirements. Therefore, setting the range of the acute angle β within the above angle range can improve the service life of the installed steering ball pin 206, and can enable the installed steering ball pin 206 to meet greater rotation requirements, and further increase the jounce stroke of the running system 13.

[0048] It should be noted that the ranges of the acute angle β formed between the above-mentioned first projection line and the first-axis projection of the axis, and the acute angle Ω formed between the second projection line and the second-axis projection of the axis are both the angle ranges when the all-terrain vehicle 100 is in a stationary state.

[0049] As Figure 8 shown, as an implementation manner, a reference plane 10b perpendicular to the height direction of the vehicle frame 11 is defined, and the rocker arm portion 2052 extends substantially along a preset straight line 10c. The acute angle Ψ formed by the preset straight line 10c and the reference plane 10b ranges from 5° to 45°. Specifically, the acute angle Ψ formed by the preset straight line 10c and the reference plane 10b ranges from 15° to 30°. The beneficial effects of the above setting manner are basically the same as those of the range setting of the acute angle β, and will not be elaborated here.

[0050] It should be noted that the range of the acute angle Ψ formed by the preset straight line 10c and the reference plane 10b is the angle range in the stationary state of the all-terrain vehicle 100.

[0051] As Figure 6 and Figure 7 shown, as an implementation manner, the steering system 20 further includes a steering assist mechanism 208. The steering assist mechanism 208 is connected to the steering tube 202 and is configured to assist the steering tube 202 to turn. Specifically, a first limiting structure 2023 is provided on the steering tube 202, and the first limiting structure 2023 is configured to cooperate with the vehicle frame 11 to limit the rotation angle of the steering tube 202. A second limiting structure 2024 is provided on the steering rocker 205, and the second limiting structure 2024 is configured to cooperate with the vehicle frame 11 to limit the rotation angle of the steering rocker 205. Due to the presence of the steering assist mechanism 208, it may cause the steering tube 202 to continue to rotate after the steering rocker 205 is limited. Through the above setting, the steering limit of the first limiting structure 2023 can be used to prevent the steering angle of the steering assist mechanism 208 assisting the steering tube 202 from being greater than the actual maximum limiting angle of the steering tube 202, resulting in excessive rotation of the steering tube 202. Thus, it can be avoided that the wire harness, pipeline, and components connected to the steering tube 202 are excessively deflected, which is beneficial to improving the service life of the wire harness, pipeline, and components connected to the steering tube 202.

[0052] It should be noted that the rotation angle of the steering tube 202 limited by the first limiting structure 2023 is the actual maximum limiting angle of the steering tube 202. In addition, the limiting angle of the second limiting structure 2024 for the steering tube 202 is the same as the limiting angle of the first limiting structure 2023 for the steering tube 202.

[0053] As an alternative implementation, the first limiting structure 2023 is located between the power steering mechanism 208 and the steering handle 201. The first limiting structure 2023 at least forms a limiting protrusion 2023a to limit the rotation angle of the steering tube 202. With such a setting, the limiting protrusion 2023a can cooperate with the vehicle frame 11 for limiting, thereby limiting the rotation angle of the steering tube 202.

[0054] As an implementation, the vehicle frame 11 includes a rotating fixing member 112 through which the steering tube 202 passes. The steering tube 202 is rotatably connected to the rotating fixing member 112. Specifically, a cooperating limiting portion 1121 is provided on the rotating fixing member 112, and the second limiting structure 2024 can cooperate with the cooperating limiting portion 1121 to limit the rotation angle of the steering rocker arm 205. In some embodiments, the second limiting structure 2024 can be a rocker arm portion 2052. The steering tube 202 drives the steering rocker arm 205 to rotate, and the rocker arm portion 2052 abuts against the limiting portion to limit the rotation angle of the steering tube 202. With such a setting, it is possible to avoid additionally installing a structure for limiting the rotation angle of the steering tube 202 on the steering tube 202, which is beneficial to simplifying the overall structure of the steering tube 202 and further beneficial to reducing the overall cost of the steering tube 202.

[0055] In addition, in this embodiment, the rocker arm portion 2052 and the limiting protrusion 2023a are respectively arranged at both ends of the power steering mechanism 208, so as to improve the limiting effect on the steering tube 202.

[0056] It should be understood that for those of ordinary skill in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of this application.
