[0032] 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.

[0033] like Figure 1 and Figure 2 An all-terrain vehicle 100 is shown, and the all-terrain vehicle 100 includes a frame 11, a travel assembly 12, a suspension assembly 13, a transmission assembly 14, a power assembly 15, a power battery 16, a seat assembly 17 and a cargo box assembly 18. The frame 11 serves as the basic framework of the all-terrain vehicle 100, and is used to support the travel assembly 12, the suspension assembly 13, the transmission assembly 14, the power assembly 15, the power battery 16, the seat assembly 17 and the cargo box assembly 18. The travel assembly 12 includes a front wheel 121 and a rear wheel 122, and the suspension assembly 13 connects the front wheel 121 and the rear wheel 122 to the frame 11. The power assembly 15 and the transmission assembly 14 are both supported by the frame 11, and the power assembly 15 is connected to at least one of the front wheel 121 and the rear wheel 122 through the transmission assembly 14, so that the power assembly 15 can drive the all-terrain vehicle 100 through the travel assembly 12. The power battery 16 is disposed on the vehicle frame 11, and the power battery 16 is electrically connected to the power assembly 15 so that the power battery 16 can supply energy to the power assembly 15. The seat assembly 17 is at least partially disposed on the vehicle frame 11, and the seat assembly 17 is used to provide support for the driver and / or passengers. The cargo box assembly 18 is at least partially disposed on the vehicle frame 11, and the cargo box assembly 18 is used to carry cargo. In the present application, the seat assembly 17 is configured as a single row of seats to save the layout space of the all-terrain vehicle 100, thereby providing sufficient layout space for the cargo box assembly 18, thereby improving the structural compactness of the all-terrain vehicle 100.

[0034] In order to clearly illustrate the technical solution of this application, the following is also defined: Figure 1 It should be noted that when the all-terrain vehicle 100 is on a flat road, the front-to-back direction refers to the length direction of the all-terrain vehicle 100, the up-down direction refers to the height direction of the all-terrain vehicle 100, and the left-right direction refers to the width direction of the all-terrain vehicle 100.

[0035] Specifically, the travel assembly 12 is disposed on the lower side of the frame 11, so as to facilitate the travel assembly 12 to drive the all-terrain vehicle 100. The suspension assembly 13 includes a front suspension 131 and a rear suspension 132, the front suspension 131 connects the front wheel 121 to the frame 11, and the rear suspension 132 connects the rear wheel 122 to the frame 11. The power assembly 15 includes a drive motor 151, and the drive motor 151 is electrically connected to the power battery 16 so that the power battery 16 supplies energy to the drive motor 151. The drive motor 151 is also transmission-connected to at least one of the front wheel 121 and the rear wheel 122 to transmit the power output by the drive motor 151 to the travel assembly 12. The cargo box assembly 18 is at least partially disposed on the rear side of the frame 11 to facilitate the loading of cargo on the all-terrain vehicle 100.

[0036] In the present application, the driving motor 151 is connected to the rear wheel 122 for transmission as an example for description, that is, the present application is described using the rear-wheel drive all-terrain vehicle 100 as an example.

[0037] like Figure 1 and Figure 2 As shown, as an implementation method, when viewed from the length direction of the all-terrain vehicle 100, the power battery 16 at least partially overlaps with the seat assembly 17, and the cargo box assembly 18 at least partially overlaps with the seat assembly 17. When viewed from the height direction of the all-terrain vehicle 100, the cargo box assembly 18 and the power battery 16 at least partially overlap, and the power battery 16 and the axis of the rear wheel 122 at least partially overlap. Specifically, the power battery 16 and the cargo box assembly 18 are at least partially arranged on the rear side of the seat assembly 17, the power battery 16 is at least partially located on the lower side of the cargo box assembly 18, and the power battery 16 is at least partially located on the upper side of the axis of the rear wheel 122, that is, along the height direction of the all-terrain vehicle 100, the power battery 16 is located between the cargo box assembly 18 and the axis of the rear wheel 122. Among them, the power battery 16 and the cargo box assembly 18 are both located at the rear of the frame 11, and the seat assembly 17 is located in the middle of the frame 11.

[0038] Through the above arrangement, the space utilization rate of the rear part of the frame 11 can be improved, so that the structure of the rear part of the frame 11 is more compact, and the space occupancy rate of the middle part of the frame 11 can be reduced, so that the height of the seat assembly 17 along the height direction of the all-terrain vehicle 100 can be reduced, so as to increase the riding space of the driver and the passenger, thereby improving the comfort of the all-terrain vehicle 100. In the present application, a cockpit 111 is formed around the middle part of the frame 11, and the riding space of the driver and the passenger is the cockpit 111. In addition, through the above arrangement, the compactness of the all-terrain vehicle 100 can be made higher, thereby meeting the design requirements of a smaller all-terrain vehicle 100, thereby realizing the miniaturization and lightness of the all-terrain vehicle 100. At the same time, the above arrangement makes the power battery 16 arranged away from the cockpit 111, so as to reduce the influence of the heat generated by the power battery 16 due to work on the cockpit 111, thereby improving the comfort of the all-terrain vehicle 100. Furthermore, through the above-mentioned arrangement, more layout space can be provided for the seat assembly 17 and the suspension assembly 13 to meet the layout requirements of different sizes or models of the seat assembly 17 and the suspension assembly 13; and the working space of the suspension assembly 13 can be increased to prevent interference between the suspension assembly 13 and other components of the all-terrain vehicle 100, so as to improve the driving performance of the all-terrain vehicle 100.

[0039] In this embodiment, the frame 11 includes a mid-frame 112 located in the middle of the frame 11 and a rear frame 113 located at the rear of the frame 11. The power battery 16 and the cargo box assembly 18 are both located in the rear frame 113, and the power battery 16 and the cargo box assembly 18 are both connected to the rear frame 113. The mid-frame 112 is surrounded by a cockpit 111, and the seat assembly 17 is located in the cockpit 111. Through the above arrangement, the space utilization rate of the rear frame 113 can be improved, so that the structure of the rear frame 113 is more compact, and at the same time, the space occupancy rate of the mid-frame 112 can be reduced to increase the riding space of the driver and passengers, thereby improving the comfort of the all-terrain vehicle 100.

[0040] like Figure 3As shown, as an implementation method, a reference plane 101 perpendicular to the height direction of the all-terrain vehicle 100 is defined, the lowermost end of the walking assembly 12 is located on the reference plane 101, the minimum distance between the upper surface of the power battery 16 and the reference plane 101 along the height direction of the all-terrain vehicle 100 is the first distance D1, the projection of the axis of the front wheel 121 along the height direction of the all-terrain vehicle 100 on the reference plane 101 is the first projection line, the projection of the axis of the rear wheel 122 along the height direction of the all-terrain vehicle 100 on the reference plane 101 is the second projection line, the minimum distance between the first projection line and the second projection line along the length direction of the all-terrain vehicle 100 is the second distance D2, and the ratio of the first distance D1 to the second distance D2 is greater than or equal to 0.3 and less than or equal to 0.58. Specifically, the ratio of the first distance D1 to the second distance D2 is greater than or equal to 0.37 and less than or equal to 0.51. More specifically, the ratio of the first distance D1 to the second distance D2 can also be 0.44.

[0041] For the small all-terrain vehicle 100, since the volume of the all-terrain vehicle 100 is small, the arrangement space of the components of the all-terrain vehicle 100 is relatively small, so the requirements for the structural compactness of the all-terrain vehicle 100 are higher. Through the above arrangement, it is possible to prevent the ratio of the first distance to the second distance from being too small, which may cause the height of the power battery 16 in the height direction of the all-terrain vehicle 100 to be too low, thereby avoiding interference between the power battery 16 and other components in the rear frame 113, so as to prevent the power battery 16 from being damaged and causing safety hazards, and improve the working stability of the power battery 16 and other components in the rear frame 113; at the same time, it can also make the arrangement of the components of the all-terrain vehicle 100 more reasonable, which is conducive to improving the structural compactness of the small all-terrain vehicle 100. In addition, through the above setting, it is also possible to prevent the ratio of the first distance to the second distance from being too large, which may cause interference between the power battery 16 and the cargo box assembly 18, or to prevent the ratio of the first distance to the second distance from being too large, which may cause insufficient arrangement space for the power battery 16, thereby preventing the power battery 16 from reducing its volume due to insufficient arrangement space, so as to increase the capacity of the power battery 16, and further improve the endurance of the all-terrain vehicle 100. Furthermore, when the ratio of the first distance to the second distance is set within the above range, the wading ability of the power battery 16 can be improved while meeting the requirements for the arrangement space of the power battery 16, thereby improving the wading ability of the small all-terrain vehicle 100; and the structure of the rear frame 113 can be made more compact, so as to improve the compactness of the structure of the small all-terrain vehicle 100.

[0042] In this embodiment, the projection of the power battery 16 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is the first projection plane, and the projection of the cargo box assembly 18 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is the second projection plane. The ratio of the area of ​​the first projection plane to the area of ​​the second projection plane is greater than or equal to 0.3 and less than or equal to 0.56. Specifically, the ratio of the area of ​​the first projection plane to the area of ​​the second projection plane is greater than or equal to 0.36 and less than or equal to 0.5. Furthermore, the ratio of the area of ​​the first projection plane to the area of ​​the second projection plane can also be 0.43. Through the above arrangement, it is possible to prevent the ratio of the area of ​​the first projection plane to the area of ​​the second projection plane from being too large, which may lead to an excessively large volume of the power battery 16, so as to avoid the increase in the weight of the all-terrain vehicle 100 and the decrease in the driving performance of the all-terrain vehicle 100; it is also possible to prevent the ratio of the area of ​​the first projection plane to the area of ​​the second projection plane from being too large, which may lead to poor structural compactness of the rear frame 113. In addition, through the above-mentioned setting, it is possible to prevent the ratio of the area of ​​the first projection surface to the area of ​​the second projection surface from being too small, resulting in the volume of the power battery 16 being too small, thereby avoiding the power of the power battery 16 being unable to meet the endurance requirements of the all-terrain vehicle 100, and is also beneficial to improving the space utilization of the rear frame 113.

[0043] like Figure 3As shown, as an implementation, when viewed from the length direction of the ATV 100, the drive motor 151 at least partially overlaps with the seat assembly 17. When viewed from the height direction of the ATV 100, the drive motor 151 and the power battery 16 at least partially overlap. Specifically, the drive motor 151 is located at the rear side of the seat assembly 17, and the drive motor 151 is located in front of the axis of the rear wheel 122, that is, the drive motor 151 is located between the seat assembly 17 and the axis of the rear wheel 122, and the drive motor 151 is also located at the lower side of the power battery 16, that is, the power battery 16 is at least partially located between the drive motor 151 and the cargo box assembly 18. Specifically, a reference plane 101 perpendicular to the height direction of the all-terrain vehicle 100 is defined, the projection of the drive motor 151 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is a first projection plane, the projection of the axis of the rear wheel 122 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is a projection line, the projection of the seat assembly 17 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is a second projection plane, and along the length direction of the all-terrain vehicle 100, the first projection plane is at least partially located between the second projection plane and the projection line. In the present application, the drive motor 151 is located in the rear frame 113 and connected to the rear frame 113; the drive motor 151 is connected to the rear wheel 122 through the transmission assembly 14. Through the above arrangement, the distance between the drive motor 151 and the transmission assembly 14 connected to the rear wheel 122 can be made closer, so that the additional transmission components between the drive motor 151 and the transmission assembly 14 can be reduced, so that the structure of the drive motor 151 and the transmission assembly 14 is more compact, and the power loss during the transmission process is reduced. In addition, through the above arrangement, the distance between the drive motor 151 and the power battery 16 can be made closer, thereby shortening the length of the wire harness between the drive motor 151 and the power battery 16, reducing the layout space of the wire harness, and then making the structure between the drive motor 151 and the power battery 16 more compact, so as to improve the structural compactness of the all-terrain vehicle 100; at the same time, it is conducive to improving the energy supply efficiency of the power battery 16 to the drive motor 151, thereby improving the working efficiency of the all-terrain vehicle 100. In this embodiment, when viewed from the height direction of the all-terrain vehicle 100, the cargo box assembly 18 and the drive motor 151 at least partially overlap.

[0044] As an implementation method, the projection of the drive motor 151 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is the first projection plane, the projection of the cargo box assembly 18 on the reference plane 101 along the height direction is the third projection plane, and the ratio of the area of ​​the third projection plane to the area of ​​the first projection plane is greater than or equal to 7.9 and less than or equal to 14.8. Specifically, the ratio of the area of ​​the third projection plane to the area of ​​the first projection plane is greater than or equal to 9.6 and less than or equal to 13.1. More specifically, the ratio of the area of ​​the third projection plane to the area of ​​the first projection plane can also be 11.4.

[0045] In this embodiment, the projection of the power battery 16 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is a fourth projection plane, and the ratio of the area of ​​the fourth projection plane to the area of ​​the first projection plane is greater than or equal to 0.14 and less than or equal to 0.27. Specifically, the ratio of the area of ​​the fourth projection plane to the area of ​​the first projection plane is greater than or equal to 0.17 and less than or equal to 0.24. More specifically, the ratio of the area of ​​the fourth projection plane to the area of ​​the first projection plane can also be 0.2.

[0046] By setting the ratio of the area of ​​the first projection surface to the area of ​​the third projection surface, and the ratio of the area of ​​the fourth projection surface to the area of ​​the first projection surface, it is possible to prevent the area of ​​the first projection surface from being too small, resulting in a small volume of the drive motor 151, thereby preventing the output power of the all-terrain vehicle 100 from being small due to the small volume of the drive motor 151, thereby improving the driving performance of the all-terrain vehicle 100; it is also possible to prevent the area of ​​the first projection surface from being too large, resulting in a large volume of the drive motor 151, thereby preventing the large volume of the drive motor 151 from causing the layout space of the drive motor 151 to be too large, thereby improving the space utilization of the drive motor 151 and the compactness of the structure of the rear frame 113. In summary, through the above settings, the output power of the drive motor 151 can meet the driving requirements of the all-terrain vehicle 100, while improving the space utilization of the drive motor 151 on the rear frame 113.

[0047] like Figure 4 As shown, as an implementation method, the rear frame 113 includes a motor mounting frame 1131 and a connecting sheet 1132. Among them, the motor mounting frame 1131 at least partially extends along the height direction of the all-terrain vehicle 100, the connecting sheet 1132 is connected to the motor mounting frame 1131, and the drive motor 151 is at least partially connected to the connecting sheet 1132. Specifically, the connecting sheet 1132 and the motor mounting frame 1131 can be connected by welding, and the drive motor 151 and the connecting sheet 1132 can be connected by bolts. Through the above arrangement, the drive motor 151 can be fixedly connected to the rear frame 113, thereby improving the connection stability of the drive motor 151, and is conducive to improving the working stability of the drive motor 151.

[0048] like Figure 5 As shown, as an implementation method, the suspension assembly 13 includes a shock absorber 1323 for providing buffering for the rear wheel 122. When viewed from the width direction of the all-terrain vehicle 100, the shock absorber 1323 and the power battery 16 at least partially overlap, so that the shock absorber 1323 can buffer the power battery 16, that is, it can reduce the impact force caused by the collision between the power battery 16 and the frame 11 due to the shaking of the power battery 16, thereby preventing safety hazards caused by damage to the power battery 16, which is beneficial to improving the service life and safety of the power battery 16.

[0049] like Figure 6 and Figure 7 As shown, as an implementation method, the seat assembly 17 includes a backrest 171, a seat cushion 172 and a seat frame 173. The seat frame 173 is arranged on the frame 11. The backrest 171 and the seat frame 173 are detachably connected so that the backrest 171 and the frame 11 are detachably connected. The seat cushion 172 and the seat frame 173 are detachably connected so that the seat cushion 172 and the frame 11 are detachably connected. When viewed from the length direction of the all-terrain vehicle 100, the backrest 171 and the power battery 16 at least partially overlap. Through the above arrangement, when the backrest 171 is disassembled, a disassembly space is formed between the seat frame 173, and the power battery 16 can be disassembled and assembled from the disassembly space, which is conducive to the replacement and maintenance of the power battery 16, so as to improve the convenience of disassembly and assembly of the power battery 16.

[0050] Specifically, the ATV 100 further includes a back plate 21, which is at least partially located between the power battery 16 and the seat assembly 17, and the back plate 21 is connected or clamped to the frame 11. The back plate 21 is used to prevent the heat generated by the power battery 16 from being transferred to the seat assembly 17, thereby improving the comfort of the driver and passengers on the seat assembly 17. Among them, a maintenance port 211 for detachably installing and installing the power battery 16 is formed on the back plate 21. When viewed from the length direction of the ATV 100, the maintenance port 211 and the backrest 171 at least partially overlap. The maintenance port 211 is also connected to the disassembly space, so that the power battery 16 can be disassembled and installed through the maintenance port 211, which is beneficial to the replacement and maintenance of the power battery 16, so as to improve the convenience of disassembly and installation of the power battery 16.

[0051] In this embodiment, the power battery 16 includes a battery housing 162 and a battery module 163 located in the battery housing 162. At least two battery modules 163 are provided, and two seat assemblies 17 are provided. When viewed from the length direction of the all-terrain vehicle 100, the backrest 171 of any seat assembly 17 overlaps with at least one battery module 163. With the above arrangement, the battery module 163 can be disassembled and assembled when only the backrest 171 of one seat assembly 17 is disassembled, thereby improving the replacement efficiency of the battery module 163.

[0052] The battery housing 162 is connected to the back plate 21 and the frame 11, and the opening of the battery housing 162 is connected to the maintenance port 211, so that the battery module 163 can be disassembled through the opening of the battery housing 162 and the maintenance port 211, so as to improve the convenience of disassembly and assembly of the battery module 163. In addition, the battery housing 162 is fixed by the back plate 21 and the frame 11 respectively, which is conducive to improving the connection stability of the battery housing 162, and then improving the working stability of the power battery 16.

[0053] In addition, the power battery 16 also includes a fixing plate 164 for fixing the battery module 163 and a battery cover 165 covering the opening of the battery housing 162. The fixing plate 164 is located between the battery module 163 and the maintenance port 211, and the fixing plate 164 is connected to the battery housing 162, so that the fixing plate 164 can prevent the battery module 163 from detaching from the battery housing 162 to improve the stability of the battery module 163. Among them, the battery cover 165 is connected to the battery housing 162, and / or the battery cover 165 is connected to the back plate 21, so that the battery cover 165 can further protect the battery module 163. In the present application, the battery cover 165 is also covered on the maintenance port 211, so that the maintenance port 211 can be hidden by the battery cover 165 to improve the integrity of the internal structure of the all-terrain vehicle 100.

[0054] like Figure 6 and Figure 7 As shown, as an implementation, the ATV 100 further includes a wiring harness assembly 22, which is electrically connected to the power assembly 15 and one of the battery modules 163. Specifically, the wiring harness assembly 22 and the battery module 163 are detachably connected, that is, the wiring harness assembly 22 can be plugged in and out of the battery module 163, thereby realizing the disassembly or electrical connection between the wiring harness assembly 22 and the battery module 163. The seat assembly 17 can move relative to the frame 11 along the length direction of the ATV 100. When the seat assembly 17 moves away from the power battery 16, the wiring harness assembly 22 can be disassembled from one of the battery modules 163 and connected to another battery module 163, thereby realizing the electrical connection between the power assembly 15 and any one of the multiple battery modules 163, and then when one battery module 163 is insufficient in power, the power assembly 15 can be electrically connected to another battery module 163 with sufficient power. Specifically, when the seat assembly 17 moves away from the power battery 16, the harness assembly 22 can switch from one battery module 163 to another battery module 163, so that when one battery module 163 is out of power, the power assembly 15 can obtain power from other battery modules 163, thereby improving the endurance of the all-terrain vehicle 100. As an optional implementation, the seat assembly 17 can be moved relative to the frame 11 by means of a slide rail provided on the frame 11.

[0055] like Figure 8 As shown, as an implementation method, a longitudinal plane 102 is defined which is perpendicular to the width direction of the all-terrain vehicle 100 and passes through the midpoint of the width direction, and the drive motor 151 is at least partially arranged in the longitudinal plane 102, so that the center of gravity of the drive motor 151 is arranged close to the center of gravity of the all-terrain vehicle 100 to improve the stability of the all-terrain vehicle 100.

[0056] Specifically, the driving motor 151 includes an output shaft 1511, which is transmission-connected to at least one of the front wheel 121 and the rear wheel 122, and the intersection between the end surface of the output shaft 1511 away from the driving motor 151 and the axis of the output shaft 1511 is the output point. The rear wheel 122 includes a first rear wheel 1221 and a second rear wheel 1222 distributed along the width direction of the all-terrain vehicle 100, and the output shaft 1511 is arranged close to the first rear wheel 1221.

[0057] A first plane 1221 a and a second plane 1222 a are defined, both perpendicular to the width direction of the all-terrain vehicle 100 . The first plane 1221 a substantially divides the first rear wheel 1221 in half, and the second plane 1222 a substantially divides the second rear wheel 1222 in half. Among them, the projection of the output point on the reference plane 101 along the height direction of the all-terrain vehicle 100 is the first projection point, the projection of the intersection of the first plane 1221a and the axis of the rear wheel 122 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is the second projection point, the projection of the intersection of the second plane 1222a and the axis of the rear wheel 122 on the reference plane 101 along the height direction of the all-terrain vehicle 100 is the third projection point, the line connecting the first projection point and the second projection point is the first line, the line connecting the second projection point and the third projection point is the second line, the line connecting the first projection point and the third projection point is the third line, the acute angle μ formed by the first line and the second line is set to be greater than or equal to 16° and less than or equal to 30°, and the acute angle λ formed by the second line and the third line is set to be greater than or equal to 14° and less than or equal to 26°. Specifically, the acute angle μ formed by the first connecting line and the second connecting line is set to be greater than or equal to 19° and less than or equal to 27°, and the acute angle λ formed by the second connecting line and the third connecting line is set to be greater than or equal to 17° and less than or equal to 23°. More specifically, the acute angle μ formed by the first connecting line and the second connecting line can also be set to 23°, and the acute angle λ formed by the second connecting line and the third connecting line can also be set to 20°. Through the above settings, it is possible to avoid the acute angle λ being too large (i.e., the acute angle μ is too small) causing the drive motor 151 to be biased toward the first rear wheel 1221, and it is also possible to avoid the acute angle λ being too small (i.e., the acute angle μ is too large) causing the drive motor 151 to be biased toward the second rear wheel 1222, thereby preventing the drive motor 151 from being too biased toward the left or right side, so as to avoid the center of gravity of the drive motor 151 being set away from the center of gravity of the all-terrain vehicle 100, thereby improving the stability of the all-terrain vehicle 100.

[0058] like Fig. 9As shown, as an implementation, the ATV 100 further includes an electrical component 23 disposed on the frame 11, and the electrical component 23 includes electrical appliances of the ATV 100 and a controller for controlling the electrical appliances. Specifically, the electrical component 23 includes a motor controller 231, the motor controller 231 is electrically connected to the drive motor 151, and the motor controller 231 is used to control the output power of the drive motor 151. In the longitudinal direction of the ATV 100, the motor controller 231 is at least partially located between the drive motor 151 and the seat assembly 17. As an optional implementation, the motor controller 231 can be installed on the frame 11 at the rear side of the seat assembly 17 through a connecting piece such as a sheet metal part. Specifically, the rear frame 113 includes a longitudinal beam 1133, the longitudinal beam 1133 is located at the rear side of the seat assembly 17, and the motor controller 231 is connected to the longitudinal beam 1133. Through the above arrangement, the motor controller 231 can be arranged close to the drive motor 151, thereby reducing the length of the wiring harness between the motor controller 231 and the drive motor 151, thereby reducing energy loss and signal instability caused by the excessive length of the wiring harness. In addition, through the above arrangement, the motor controller 231 can also be separated from the drive motor 151, thereby reducing the volume of the drive motor 151, which is beneficial to the arrangement of the drive motor 151. In the present application, the motor controller 231 is at least partially located on the front side of the power battery 16 and at least partially located on the lower side of the power battery 16.

[0059] It is understandable that the motor controller 231 may also be located at any position of the rear frame 113 , as long as the motor controller 231 is arranged close to the drive motor 151 .

[0060] In this embodiment, the minimum distance D3 between the motor controller 231 and the drive motor 151 is set to be greater than or equal to 19.7 mm and less than or equal to 36.7 mm. Specifically, the minimum distance D3 between the motor controller 231 and the drive motor 151 is set to be greater than or equal to 23.9 mm and less than or equal to 32.5 mm. More specifically, the minimum distance D3 between the motor controller 231 and the drive motor 151 can also be set to 28.2 mm. Through the above settings, it is possible to avoid the minimum distance between the motor controller 231 and the drive motor 151 being too large, resulting in the wiring harness between the motor controller 231 and the drive motor 151 being too long, thereby reducing the energy loss caused by the long wiring harness, and preventing the signal between the motor controller 231 and the drive motor 151 from being unstable; it is also possible to avoid the minimum distance between the motor controller 231 and the drive motor 151 being too small, so that the heat generated by the drive motor 151 has an adverse effect on the motor controller 231, thereby avoiding overheating and damage to the motor controller 231, so as to improve the service life of the motor controller 231.

[0061] like Figure 1 and Figure 2 As shown, as an implementation, the transmission assembly 14 includes a rear axle mechanism 141, which is connected to the frame 11. Specifically, the rear axle mechanism 141 is arranged in the rear frame 113 and connected to the rear frame 113. The rear axle mechanism 141 is connected to the drive motor 151 by transmission, and the rear axle mechanism 141 is connected to the rear wheel 122 by transmission, so that the power output by the drive motor 151 can be transmitted to the rear wheel 122 through the rear axle mechanism 141, so that the rear wheel 122 can drive the all-terrain vehicle 100 to move. As an optional implementation, the rear axle mechanism 141 and the drive motor 151 are connected by chain drive or belt drive, so as to facilitate the replacement and maintenance of the transmission structure between the rear axle mechanism 141 and the drive motor 151. In this embodiment, when viewed from the height direction of the all-terrain vehicle 100, the rear axle mechanism 141 and the power battery 16 at least partially overlap. Along the length direction of the ATV 100 , the drive motor 151 is at least partially located between the rear axle mechanism 141 and the seat assembly 17 to shorten the distance between the drive motor 151 and the rear axle mechanism 141 , thereby improving the transmission efficiency between the drive motor 151 and the rear axle mechanism 141 .

[0062] like Fig.10 As shown, as an implementation, the rear suspension 132 includes a longitudinal arm integral part 1321 and a mounting bracket 1322. One end of the longitudinal arm integral part 1321 is rotatably connected to the vehicle frame 11, and the other end of the longitudinal arm integral part 1321 is rotatably connected to the mounting bracket 1322, and the mounting bracket 1322 is also connected to the rear wheel 122, so that the longitudinal arm integral part 1321 can connect the rear wheel 122 to the vehicle frame 11 through the mounting bracket 1322. The mounting bracket 1322 and the rear wheel 122 are fixedly connected, for example, the mounting bracket 1322 and the rear wheel 122 can be fixedly connected by bolts and nuts.

[0063] Specifically, the frame 11 includes a main frame 114, which extends substantially along the length direction of the all-terrain vehicle 100. The main frame 114 is a main body supporting the travel assembly 12, the suspension assembly 13, the power assembly 15, the power battery 16, the seat assembly 17 and the cargo box assembly 18, and is the main part of the frame 11. The end of the longitudinal arm integral part 1321 away from the mounting bracket 1322 is rotatably connected to the main frame 114. Through the above-mentioned arrangement, the mounting bracket 1322 on which the rear wheel 122 is fixed can be rotatably connected to the longitudinal arm integral part 1321, thereby realizing the rotation of the rear wheel 122; at the same time, the integrally arranged longitudinal arm integral part 1321 can improve the assembly accuracy of the rear wheel 122 and the transmission component 14, that is, the position and angle of the longitudinal arm integral part 1321 can be adjusted according to actual conditions to meet the different assembly requirements of the rear wheel 122 and the transmission component 14, thereby preventing the transmission efficiency and transmission reliability of the rear wheel 122 and the transmission component 14 from being reduced due to insufficient assembly accuracy of the rear wheel 122 and the transmission component 14, which is beneficial to improving the transmission efficiency and transmission reliability of the walking component 12 and the transmission component 14, and is beneficial to the disassembly and assembly of the rear wheel 122 and the transmission component 14, so as to improve the assembly performance of the rear wheel 122 and the transmission component 14.

[0064] In this embodiment, the longitudinal arm integral part 1321 includes a longitudinal arm main body 1321a and a wheel axle support 1321b, one end of the longitudinal arm main body 1321a is rotatably connected to the main frame 114, the other end of the longitudinal arm main body 1321a is welded with the wheel axle support 1321b, and the wheel axle support 1321b is rotatably connected to the mounting bracket 1322. Through the above arrangement, the assembly accuracy between the longitudinal arm main body 1321a and the wheel axle support 1321b can be improved, so that the position and angle of the longitudinal arm integral part 1321 can be adjusted according to actual conditions to meet the different assembly requirements of the rear wheel 122 and the transmission assembly 14. In addition, welding the longitudinal arm main body 1321a and the wheel axle support 1321b can simplify the processing procedures of the longitudinal arm integral part 1321, thereby improving the processing efficiency of the longitudinal arm integral part 1321 and reducing labor costs. Furthermore, the above arrangement can facilitate detection of the dimensional accuracy of the longitudinal arm integral part 1321 to reduce assembly errors, thereby improving the controllability of the position and angle of the longitudinal arm integral part 1321 to meet different assembly requirements of the rear wheel 122 and the transmission assembly 14 .

[0065] As an optional implementation, the longitudinal arm integrated part 1321 includes a bearing seat 1321c and a connecting member 1321d. The bearing seat 1321c is arranged at one end of the longitudinal arm body 1321a that is rotatably connected to the main frame 114. The bearing seat 1321c and the longitudinal arm body 1321a are fixedly connected. The bearing seat 1321c and the main frame 114 are rotatably connected through the connecting member 1321d, so that the longitudinal arm integrated part 1321 can rotate relative to the main frame 114, so as to facilitate the longitudinal arm integrated part 1321 to swing up and down. Specifically, the bearing seat 1321c and the longitudinal arm body 1321a can be connected by a fixed method such as welding; the connecting member 1321d can be set as a ball pin, so as to facilitate the rotation connection between the bearing seat 1321c and the main frame 114.

[0066] As an implementation method, the rear suspension 132 also includes a shock absorber 1323, which is used to buffer the rear wheel 122, thereby improving the driving comfort of the all-terrain vehicle 100. One end of the shock absorber 1323 is rotatably connected to the main frame 114, and the other end of the shock absorber 1323 is rotatably connected to the longitudinal arm body 1321a. Specifically, the longitudinal arm integrated part 1321 includes a first mounting member 1321e, the first mounting member 1321e is fixedly connected to the longitudinal arm body 1321a, and the shock absorber 1323 is rotatably connected to the first mounting member 1321e. Through the above arrangement, the mounting structure of the shock absorber 1323 can be integrated on the longitudinal arm body 1321a, thereby reducing the additional mounting structure of the shock absorber 1323, so as to improve the structural compactness of the all-terrain vehicle 100. At the same time, by setting the first mounting member 1321e, the position of the shock absorber 1323 on the longitudinal arm body 1321a can be adjusted according to actual needs, and it is only necessary to adjust the structure and / or position of the first mounting member 1321e when processing the longitudinal arm body 1321a.

[0067] In the present application, the all-terrain vehicle 100 further includes a brake assembly 19 (see Figure 1), the brake assembly 19 includes a brake oil pipe filled with brake fluid (not shown), a brake of the brake travel assembly 12, and an operating mechanism for controlling the brake. Specifically, the operating mechanism can control the hydraulic pressure of the brake fluid in the brake oil pipe, thereby braking the travel assembly 12 through the hydraulic control brake. Among them, the longitudinal arm integrated part 1321 includes a second mounting part (not shown), the second mounting part is fixedly connected to the longitudinal arm body 1321a, and the brake oil pipe is connected to the second mounting part, so that the brake oil pipe can be limited by the second mounting part, thereby preventing the brake oil pipe from shaking during the movement of the all-terrain vehicle 100, so as to avoid the brake oil pipe colliding with other parts of the all-terrain vehicle 100 and causing wear, and further improve the service life of the brake oil pipe. In this embodiment, the second mounting part can be connected to any position of the longitudinal arm body 1321a, and the second mounting part can also be provided in plurality, that is, the number of the second mounting parts and the setting position on the longitudinal arm body 1321a are not limited. Through the above arrangement, the mounting structure of the brake oil pipe can be integrated on the trailing arm body 1321a, thereby reducing the additional mounting structure of the brake oil pipe, so as to improve the structural compactness of the all-terrain vehicle 100.

[0068] As an implementation method, along the width direction of the all-terrain vehicle 100, both sides of the main frame 114 are connected with a longitudinal arm integral part 1321, that is, two longitudinal arm integral parts 1321 are provided, so that the longitudinal arm body 1321a includes a first longitudinal arm 1321g and a second longitudinal arm 1321h distributed on both sides of the main frame 114, and the first longitudinal arm 1321g and the second longitudinal arm 1321h are both rotatably connected to the main frame 114.

[0069] The suspension assembly 13 includes a stabilizer bar 133 and a connecting rod mechanism 134. The stabilizer bar 133 is connected to the longitudinal arm body 1321a, and the connecting rod mechanism 134 is rotatably connected to the main frame 114 and the wheel axle support 1321b, respectively. The stabilizer bar 133 and the connecting rod mechanism 134 are used to improve the driving stability of the all-terrain vehicle 100. The stabilizer bar 133 basically extends along the width direction of the all-terrain vehicle 100.

[0070] Specifically, the longitudinal arm integral part 1321 further includes a third mounting member 1321j, the first longitudinal arm 1321g and the second longitudinal arm 1321h are both provided with the third mounting member 1321j, and the stabilizer bar 133 is respectively connected to the first longitudinal arm 1321g and the second longitudinal arm 1321h through the third mounting member 1321j. Through the above arrangement, the mounting structure of the stabilizer bar 133 can be integrated on the longitudinal arm body 1321a, thereby reducing the additional mounting structure of the stabilizer bar 133, so as to improve the structural compactness of the all-terrain vehicle 100.

[0071] It should be noted that the first mounting member 1321e, the second mounting member, and the third mounting member 1321j in the present application can all be set as sheet metal parts, so as to facilitate the processing and structural deformation of the first mounting member 1321e, the second mounting member, and the third mounting member 1321j to meet the layout requirements of different components. The first mounting member 1321e, the second mounting member, and the third mounting member 1321j can be connected to the longitudinal arm body 1321a by welding.

[0072] like Fig.10 and Fig.11 As shown, in this embodiment, the structures of the first longitudinal arm 1321g and the second longitudinal arm 1321h are basically the same. Here, the structure of the first longitudinal arm 1321g is taken as an example for explanation. The first longitudinal arm 1321g is formed by bending a pipe and is divided into a first rocker arm 1321k and a second rocker arm 1321m at the bending point, that is, the first longitudinal arm 1321g includes an integrally formed first rocker arm 1321k and a second rocker arm 1321m. Through the above arrangement, the processing difficulty of the first longitudinal arm 1321g can be reduced, and the processing steps of the first longitudinal arm 1321g can be reduced, thereby reducing the production cost of the first longitudinal arm 1321g. Among them, the first rocker arm 1321k is rotatably connected to the main frame 114, and the second rocker arm 1321m is welded with a wheel axle support 1321b.

[0073] As an implementation, the first rocker arm 1321k extends substantially along the direction of the first preset straight line 1321n, and the second rocker arm 1321m extends substantially along the direction of the second preset straight line 1321p, defining a longitudinal plane 102 perpendicular to the width direction of the all-terrain vehicle 100, and the acute angle α formed between the first preset straight line 1321n and the longitudinal plane 102 is set to be greater than or equal to 7° and less than or equal to 15°, and the acute angle β formed between the second preset straight line 1321p and the longitudinal plane 102 is set to be greater than or equal to 39° and less than or equal to 73°. Specifically, the acute angle α formed between the first preset straight line 1321n and the longitudinal plane 102 is set to be greater than or equal to 9° and less than or equal to 13°, and the acute angle β formed between the second preset straight line 1321p and the longitudinal plane 102 is set to be greater than or equal to 47° and less than or equal to 65°. More specifically, the acute angle α formed between the first preset straight line 1321n and the longitudinal plane 102 can also be set to 11°, and the acute angle β formed between the second preset straight line 1321p and the longitudinal plane 102 can also be set to 56°. Through the above settings, it is possible to prevent the acute angle α or the acute angle β from being too large so that the first longitudinal arm 1321g extends too far outward, thereby preventing the first longitudinal arm 1321g from occupying too much width space of the all-terrain vehicle 100, thereby improving the space utilization and structural compactness of the all-terrain vehicle 100. In addition, through the above settings, it is also possible to prevent the acute angle α or the acute angle β from being too small so that the first longitudinal arm 1321g interferes with other components of the all-terrain vehicle 100, for example, it is possible to prevent the first longitudinal arm 1321g from interfering with the drive motor 151, the frame 11, etc., thereby improving the working stability of the first longitudinal arm 1321g and other components of the all-terrain vehicle 100.

[0074] like Fig.12 and Fig.13 As shown, as an implementation, the all-terrain vehicle 100 further includes a steering assembly 24, which is at least partially rotatably connected to the vehicle frame 11, and is used to control the movement direction of the all-terrain vehicle 100. Specifically, the steering assembly 24 includes a rotating mechanism 241 and a direction control mechanism 242, the rotating mechanism 241 is rotatably connected to the vehicle frame 11, the direction control mechanism 242 is transmission-connected to the rotating mechanism 241, and the direction control mechanism 242 is also transmission-connected to the front wheel 121, so that the rotating mechanism 241 can drive the front wheel 121 to steer through the direction control mechanism 242.

[0075] In this embodiment, a receiving space 115 is formed around the front side of the frame 11, and the direction control mechanism 242 is at least partially located in the receiving space 115, defining a first plane 103 perpendicular to the length direction of the all-terrain vehicle 100 and passing through the axis of the front wheel 121, and the direction control mechanism 242 is located in front of the first plane 103. Through the above arrangement, the direction control mechanism 242 can be located in front of the axis of the front wheel 121, so that the direction control mechanism 242 is away from the cockpit 111 (refer to Figure 1 ) is set to prevent the steering assembly 24 from interfering with the plastic parts around the cockpit 111 during operation, which is beneficial to improving the working stability of the steering assembly 24.

[0076] In addition, if the direction control mechanism 242 is arranged at the rear side of the axis of the front wheel 121, the rotation mechanism 241 will obtain a larger initial installation angle, which is not conducive to the steering of the all-terrain vehicle 100. Therefore, an additional transmission structure needs to be added to enable the rotation mechanism 241 to be transmission-connected with the direction control mechanism 242. Through the above arrangement, the transmission structure between the rotation mechanism 241 and the direction control mechanism 242 can be saved, thereby simplifying the structure of the steering assembly 24, thereby improving the structural compactness of the steering assembly 24, and improving the space utilization rate of the front side of the frame 11.

[0077] Furthermore, by arranging the direction control mechanism 242 on the front side of the axis of the front wheel 121, the space behind the axis of the front wheel 121 can be saved, so that it is convenient to arrange other components on the axis of the front wheel 121. For example, when the driving mode of the all-terrain vehicle 100 is four-wheel drive, the front axle mechanism can be arranged in the space behind the axis of the front wheel 121. Alternatively, the above arrangement can also be applied to steering assemblies 24 of different sizes to improve the versatility of the all-terrain vehicle 100. In addition, for the small all-terrain vehicle 100, due to the small size of the small all-terrain vehicle 100, the above arrangement can also make the structure of the front part of the small all-terrain vehicle 100 more compact, so as to facilitate the arrangement of other components on the small all-terrain vehicle 100 to improve the space utilization of the small all-terrain vehicle 100.

[0078] As an optional implementation, the suspension assembly 13 includes a front swing arm 136, which connects the front wheel 121 and the frame 11, so that the front wheel 121 can jump up and down through the front swing arm 136 during the driving of the all-terrain vehicle 100. Specifically, a second plane 104 perpendicular to the length direction of the all-terrain vehicle 100 and passing through the front end of the front swing arm 136 is defined, and the direction control mechanism 242 is located between the first plane 103 and the second plane 104. Among them, the second plane 104 is located on the front side of the first plane 103. Through the above arrangement, not only can the beneficial effects brought by the direction control mechanism 242 being located on the front side of the first plane 103 be achieved, but also the space in front of the second plane 104 can be saved, so as to facilitate the arrangement of other components in the space in front of the second plane 104, thereby further improving the space utilization of the front side of the frame 11 and improving the structural compactness of the front side of the frame 11.

[0079] In this embodiment, a mounting member 116 is provided on the vehicle frame 11. When viewed from the width direction of the all-terrain vehicle 100, the mounting member 116 at least partially overlaps with the front rocker arm 136, and the direction control mechanism 242 is connected to the vehicle frame 11 through the mounting member 116. Optionally, the mounting member 116 can be provided as a sheet metal part, which is conducive to the processing and structural deformation of the mounting member 116 to meet different setting requirements of the direction control mechanism 242. Specifically, the mounting member 116 can be connected to the vehicle frame 11 by a fixing method such as welding, and the mounting member 116 can be connected to the direction control mechanism 242 by a fixing method such as bolts and nuts, which is not limited here.

[0080] As an implementation, the suspension assembly 13 includes a steering knuckle 137, which is rotatably connected to the front wheel 121. The steering knuckle 137 at least partially extends forward to form a connecting seat 1371, and the connecting seat 1371 is used to connect with the steering assembly 24 to control the steering of the all-terrain vehicle 100. Through the above arrangement, the connecting seat 1371 can be matched with the position of the direction control mechanism 242, so that the connection between the connecting seat 1371 and the steering assembly 24 can be more stably connected, thereby improving the working stability of the steering assembly 24.

[0081] Specifically, the steering assembly 24 includes a steering tie rod 243, which is movably connected to the direction control mechanism 242, and the steering tie rod 243 is also rotatably connected to the connecting seat 1371. Through the above arrangement, the rotation mechanism 241 can drive the direction control mechanism 242, so that the direction control mechanism 242 can drive the steering knuckle 137 through the steering tie rod 243, thereby enabling the front wheel 121 located on the steering knuckle 137 to steer, so as to achieve the steering of the all-terrain vehicle 100.

[0082] More specifically, the steering rod 243 is at least partially located on the front side of the first plane 103, and the connecting seat 1371 is at least partially located on the front side of the first plane 103, so that the steering rod 243 can cooperate with the position of the direction control mechanism 242 and the connecting seat 1371, so that the connection between the connecting seat 1371 and the steering rod 243 can be more stably connected, and the connection between the direction control mechanism 242 and the steering rod 243 can be more stably connected, thereby improving the working stability of the steering assembly 24.

[0083] Optionally, the knuckle 137 at least partially extends backward to form a caliper seat 1372, and the brake is connected to the caliper seat 1372. Through the above arrangement, the brake can be located at the rear side of the knuckle 137, thereby reducing the number of parts around the brake, which is beneficial to the heat dissipation of the brake. At the same time, the connection seat 1371 is arranged at the front side of the knuckle 137, and the space at the rear side of the knuckle 137 can also be used to set the caliper seat 1372, which is beneficial to increase the windward area of ​​the brake, so as to further improve the heat dissipation efficiency of the brake.

[0084] As an implementation method, the direction control mechanism 242 includes an outer shell 2421 and a transmission member 2422 located in the outer shell 2421, and the transmission member 2422 is transmission-connected to the steering rod 243 and the rotating mechanism 241, so that the rotating mechanism 241 can drive the steering rod 243 to work through the transmission member 2422. Specifically, the transmission member 2422 includes a transmission end and a connection end, the transmission end is transmission-connected to the rotating mechanism 241, and the connection end is movably connected to the steering rod 243. Among them, an adjustment mechanism 244 capable of adjusting the length of the steering rod 243 is provided at one end of the steering rod 243 away from the connection end, the steering rod 243 is sleeved on the adjustment mechanism 244 and is threadedly connected to the adjustment mechanism 244, and the adjustment mechanism 244 is rotationally connected to the connecting seat 1371. As an optional implementation, the adjustment mechanism 244 may include a threaded end with an external thread and a ball head end rotatably connected to the connection seat 1371, and the steering rod 243 may be built with a threaded hole, so that the threaded end of the adjustment mechanism 244 can cooperate with the steering rod 243 to adjust the distance between the steering rod 243 and the connection seat 1371, thereby improving the versatility of the steering rod 243. The ball head end of the adjustment mechanism 244 can be set as a ball head structure, so as to facilitate the rotational connection between the adjustment mechanism 244 and the connection seat 1371.

[0085] like Fig.14As shown, as an implementation, the all-terrain vehicle 100 includes a passenger armrest mechanism 25, and the passenger armrest mechanism 25 includes a connecting frame 251, an armrest frame 252, and an adjusting member 253. The connecting frame 251 is connected to the vehicle frame 11, and specifically, the connecting frame 251 can be connected to the vehicle frame 11 by a fixed method such as welding. The armrest frame 252 can move relative to the connecting frame 251, and the adjusting member 253 is used to adjust the relative position of the connecting frame 251 and the armrest frame 252, that is, the adjusting member 253 can control the relative movement of the armrest frame 252 and the connecting frame 251.

[0086] Specifically, the connecting frame 251 is sleeved on the handrail frame 252, and the connecting frame 251 is provided with a notch portion 2511 near the handrail frame 252. The adjusting member 253 includes a fastening portion 2531 and an adjusting portion 2532, and the fastening portion 2531 is sleeved on the notch portion 2511. The adjusting portion 2532 includes a first position and a second position. When the adjusting portion 2532 is in the first position, the adjusting portion 2532 drives the fastening portion 2531 to squeeze the notch portion 2511, so that the notch portion 2511 is deformed to increase the pre-tightening force between the fastening portion 2531 and the notch portion 2511. At this time, the force of the fastening portion 2531 on the notch portion 2511 is greater than or equal to the preset force, so that the connecting frame 251 and the handrail frame 252 are relatively stationary. When the adjusting portion 2532 is in the second position, the fastening portion 2531 is in a relaxed state, so that the notch portion 2511 returns to the initial position, that is, when the fastening portion 2531 is in a relaxed state, the notch portion 2511 can return to the state before deformation, so that the force exerted by the fastening portion 2531 on the notch portion 2511 is less than the preset force, so that the connection frame 251 and the armrest frame 252 can move relative to each other. In the present application, the preset force that can make the connection frame 251 and the armrest frame 252 relatively still means that the pre-tightening force between the fastening portion 2531 and the notch portion 2511 can prevent the fastening portion 2531 and the notch portion 2511 from moving relative to each other. Through the above arrangement, the distance between the armrest frame 252 and the connection frame 251 can be adjusted to meet the use needs of different passengers.

[0087] Through the above configuration of the all-terrain vehicle 100, the structure of the all-terrain vehicle 100 can be made more compact to meet the design requirements of a small all-terrain vehicle 100. Specifically, through the above configuration, the height H of the all-terrain vehicle 100 along its height direction can be made smaller, so that it is easier for drivers with shorter heights such as children to drive the all-terrain vehicle 100, and the all-terrain vehicle 100 can be miniaturized.

[0088] like Fig.15As shown, the height H of the all-terrain vehicle 100 along its height direction is set to be greater than or equal to 1080 mm and less than or equal to 1620 mm. Specifically, the height H of the all-terrain vehicle 100 along its height direction is set to be greater than or equal to 1210 mm and less than or equal to 1490 mm. More specifically, the height H of the all-terrain vehicle 100 along its height direction is set to 1352 mm. Through the above setting, it is possible to avoid that the height H is too large, which causes a driver with shorter height, such as a child, to be unable to drive the all-terrain vehicle 100, and it is also possible to avoid that the height H is too small to fail to meet the layout requirements of the components of the all-terrain vehicle 100, that is, it is also possible to avoid that the height H is too small to fail to meet the layout space required for the components of the all-terrain vehicle 100, so that the compactness of the structure of the all-terrain vehicle 100 can be improved while meeting the layout requirements of the components of the all-terrain vehicle 100, thereby facilitating the driving of the all-terrain vehicle 100 by drivers with shorter height, such as children, and realizing the miniaturization of the all-terrain vehicle 100.

[0089] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
