As shown in fig. 2 and 3, the power assembly 15 includes a driving motor 151, a power battery 153, and a motor controller 152. The driving motor 151 is at least partially connected to the power battery 153, and the driving motor 151 is also at least partially connected to the motor controller 152. The power battery 153 may supply power to the driving motor 151. The motor controller 152 is used to control the operation of the driving motor 151 so that the driving motor 151 drives the all-terrain vehicle 100 to move. Specifically, the driving motor 151 is further connected to the transmission assembly 17, so that the motion of the walking assembly 13 is driven by the transmission assembly 17. In the present embodiment, the power battery 153 supplies power to the driving motor 151 in a case where the all-terrain vehicle 100 is in a preset state. The preset state refers to a state in which the power battery 153 of the all-terrain vehicle 100 is in an electric power output.
As one implementation, the power battery 153 is at least partially disposed between the first travel wheel 131 and the second travel wheel 132, and the power battery 153 is also at least partially located below the seat 16. The drive motor 151 is at least partially located at the rear 112 of the frame 11, and the drive motor 151 is also at least partially located between the first rear wheel 1321 and the second rear wheel 1322. The power battery 153 may be an energy type battery. By the arrangement, the driving motor 151 can be positioned at the rear part 112 of the frame 11, and the power battery 153 can be positioned at the middle position of the all-terrain vehicle 100, so that the gravity center distribution of the all-terrain vehicle 100 is reasonable, and the stability of the all-terrain vehicle 100 during running is improved. In addition, through the arrangement, the power battery 153 can be far away from the driving motor 151, so that the influence of heat generated by the driving motor 151 on the power battery 153 is small, the influence of the heat generated by the power battery 153 on the driving motor 151 is small, the heat dissipation effect of the power battery 153 and the driving motor 151 is improved, the damage of the power battery 153 and the driving motor 151 caused by overheating is prevented, and the service lives of the power battery 153 and the driving motor 151 are prolonged. Further, by setting the positions of the power battery 153 and the driving motor 151, the space utilization rate of the all-terrain vehicle 100 is improved in the case that the arrangement space of the all-terrain vehicle 100 is small; through the arrangement, the stability of the all-terrain vehicle 100 is improved, and the safety of the all-terrain vehicle 100 running on different road conditions is improved conveniently. In addition, setting the power battery 153 as an energy type battery is beneficial to improving the endurance of the power battery 153, so as to meet the endurance requirement of the all-terrain vehicle 100 in the driving process, facilitate improving the endurance of the all-terrain vehicle 100, and further meet the operation requirement of a driver, for example, for an agricultural all-terrain vehicle, the energy type battery is adopted to improve the endurance of the agricultural all-terrain vehicle, and the requirement of a user for pulling the goods is met.
Specifically, an accommodation space is formed below the seat 16, and the power battery 153 is located in the accommodation space below the seat 16. With the above arrangement, the power battery 153 can be made to use of the space under the seat 16, thereby improving the space utilization under the seat 16. In the present embodiment, the inner contour of the accommodation space under the seat 16 is substantially identical to the outer contour of the power battery 153, so that the power battery 153 can be fixed through the accommodation space, the fixing structure of the power battery 153 can be saved, the structure of the all-terrain vehicle 100 can be simplified, and the structural compactness of the all-terrain vehicle 100 can be improved.
On a symmetry plane 101 perpendicular to the left-right direction of the ATV 100, the ATV 100 is disposed substantially symmetrically about the symmetry plane 101. Specifically, the power cells 153 are disposed substantially symmetrically about the plane of symmetry 101, and the drive motor 151 is disposed substantially symmetrically about the plane of symmetry 101. Through the arrangement, the gravity center distribution of the all-terrain vehicle 100 can be reasonable, and the stability of the all-terrain vehicle 100 during running can be improved, so that the safety of the all-terrain vehicle 100 during running can be improved. In addition, the power battery 13 has a certain weight, and by the arrangement, the layout of the power battery 153 on the all-terrain vehicle 100 can be more reasonable, so that the stability of the all-terrain vehicle 100 is improved. In this embodiment, the power battery 153 extends substantially in the left-right direction of the all-terrain vehicle 100, so that the volume of the power battery 153 can be increased, the power battery 153 with larger capacity can be conveniently arranged, and the power performance and cruising ability of the all-terrain vehicle 100 can be further improved.
It will be appreciated that the power cells 153 may also be disposed asymmetrically with respect to the plane of symmetry 101, and that the drive motor 151 may also be disposed asymmetrically with respect to the plane of symmetry 101. By the arrangement, the arrangement of the power battery 153 and the driving motor 151 can be more flexible, so that the space utilization rate of the all-terrain vehicle 100 is improved, and the structural compactness of the all-terrain vehicle 100 is further improved.
In this application, because the road condition on which the all-terrain vehicle 100 travels is complex, the stability requirement on the all-terrain vehicle 100 is high, and therefore, the power battery 153 and the driving motor 151 of the all-terrain vehicle 100 of this application are all substantially symmetrically arranged about the symmetry plane 101.
As an implementation manner, during the running process of the all-terrain vehicle 100, the energy type battery can improve the endurance of the power battery 153, so that the driving motor 151 continuously outputs power to the walking assembly 13, and further meets the power requirement and the endurance requirement of the all-terrain vehicle 100.

In the present embodiment, the rated capacity of the power battery 153 is 52AH or more and 56AH or less, and the discharge rate of the power battery 153 may be 4C. Through the arrangement, the cruising ability of the power battery 153 can be improved, so that the cruising requirement of the all-terrain vehicle 100 in the running process is met, the cruising ability of the all-terrain vehicle 100 is conveniently improved, and the operation requirement of a driver is further met. In addition, through the arrangement, the cost of the all-terrain vehicle 100 can be saved under the condition of meeting the power requirement and the cruising requirement of the all-terrain vehicle 100, and the resource utilization rate of the all-terrain vehicle 100 can be improved.

Specifically, the driving motor 151 directly drives the second traveling wheel 132, that is, the driving motor 151 is used to drive the second traveling wheel 132. The driving motor 151 also drives the first traveling wheel 131 through the driving shaft 171. With the above arrangement, four-wheel drive of the ATV 100 can be achieved, thereby improving the trafficability of the ATV 100. In the present embodiment, the transmission assembly 17 further includes a front axle mechanism 172, and the front axle mechanism 172 is used to connect the first traveling wheel 131 and the transmission shaft 171.
