Frame 11 includes a front portion 111 and a rear portion 112. The seat 16 is disposed between a front portion 111 and a rear portion 112 of the frame 11. The frame 11 and the body panel 12 are formed with a cabin 19, and the seat 16 is also provided in the cabin 19. The first road wheel 131 includes a first front wheel 1311 and a second front wheel 1312, and the second road wheel 132 includes a first rear wheel 1321 and a second rear wheel 1322.

As shown in fig. 2 and 3, the power assembly 15 includes a drive motor 151, a range extender assembly 152, a power battery 153, and a motor controller 154. The driving motor 151 is at least partially connected with the range extender assembly 152, the driving motor 151 is at least partially connected with the power battery 153, and the driving motor 151 is also at least partially connected with the motor controller 154. The range extender assembly 152 is connected to a power battery 153. The range extender assembly 152 and the power battery 153 may each provide power to the drive motor 151. The motor controller 154 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 booster Cheng Qizong to 152 is used to charge the power battery 153 and/or to supply power to the drive motor 151 in the case where the all-terrain vehicle 100 is in a preset state. Wherein the preset state refers to a state in which the range extender assembly 152 of the ATV 100 is in operation. Specifically, ATV 100 includes a first preset state, a second preset state, and a third preset state. When the ATV 100 is in the first preset state, the range extender assembly 152 charges the power battery 153, and the power battery 153 can supply power to the driving motor 151, so that the driving motor 151 drives the ATV 100 to move. When ATV 100 is in the second preset state, power generated by range extender assembly 152 is provided to drive motor 151, thereby causing drive motor 151 to drive ATV 100 in motion. When the all-terrain vehicle 100 is in the third preset state, the electric power generated by the power generation units Cheng Qizong to 152 is partially supplied to the power battery 153 for charging the power battery 153; another portion of the power generated by the motor Cheng Qizong to 152 is provided to the drive motor 151 for powering the drive motor 151, thereby causing the drive motor 151 to drive the ATV 100 in motion. Through the arrangement, the power battery 153 and/or the range extender assembly 152 can be used for providing power for the driving motor 151, and the range extender assembly 152 can be used for charging the power battery 153, so that different power supply functions of the range extender assembly 152 are realized, the energy supply mode of the all-terrain vehicle 100 is increased, the power requirements of the all-terrain vehicle 100 under different road conditions are further met, and the driving comfort and the interestingness of a driver are improved conveniently.

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 range extender assembly 152 is at least partially located at the rear portion 112 of the frame 11, and the range extender assembly 152 is also at least partially located between the first rear wheel 1321 and the second rear wheel 1322. 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 a power type battery. By the arrangement, the increase Cheng Qizong and the driving motor 151 can be positioned at the rear part 112 of the frame 11, 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 range extender assembly 152 and the driving motor 151, so that the influence of heat generated by the range extender assembly 152 and the driving motor 151 on the power battery 153 is small, the influence of the heat generated by the power battery 153 on the range extender assembly 152 and the driving motor 151 is small, the heat dissipation effect of the power battery 153, the range extender assembly 152 and the driving motor 151 is improved, the damage of the power battery 153, the range extender assembly 152 and the driving motor 151 caused by overheat is prevented, and the service lives of the power battery 153, the range extender assembly 152 and the driving motor 151 are prolonged. Further, by setting the positions of the power battery 153, the range extender assembly 152 and the driving motor 151, the space utilization rate of the all-terrain vehicle 100 is improved under the condition 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, the power battery 153 is set to be a power type battery, which is favorable for improving the output power of the power battery 153 and combining the power output by the power battery 153 with the power output of the power battery Cheng Qizong, thereby meeting the power requirement of the all-terrain vehicle 100 in the running process, being convenient for improving the off-road capability, the escaping capability and the power performance of the all-terrain vehicle 100 and further improving the driving comfort and the interestingness of a driver.

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 range extender assembly 152 is disposed substantially symmetrically about the plane of symmetry 101, the power battery 153 is 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 the present 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 a larger capacity can be conveniently provided, and the power performance of the all-terrain vehicle 100 can be improved.

It will be appreciated that the range extender assembly 152 may be disposed asymmetrically with respect to the plane of symmetry 101, the power battery 153 may be disposed asymmetrically with respect to the plane of symmetry 101, and the drive motor 151 may be disposed asymmetrically with respect to the plane of symmetry 101. Through the arrangement, the arrangement of the power battery 153, the power generator Cheng Qizong 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 that the all-terrain vehicle 100 travels is complex, the stability requirement of the all-terrain vehicle 100 is high, and therefore, the range extender assembly 152, 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 power battery can increase the output power of the power battery 153, so that the driving motor 151 outputs greater power to the walking assembly 13, thereby meeting the power requirement of the all-terrain vehicle 100. Specifically, the peak discharge rate of the power battery 153 is 13C or more and 18C or less, or the peak discharge rate of the power battery 153 is 13C or more and 15C or less; the sustained discharge rate of the power battery 153 is 8C or more and 13C or less, or the sustained discharge rate of the power battery 153 is 8C or more and 10C or less; the rated capacity of the power battery 153 is 14kwh or more and 17kwh or less. Through the arrangement, the output power of the power battery 153 can be improved, so that the power requirement of the all-terrain vehicle 100 in the running process is met, the off-road capability, the escaping capability and the power performance of the all-terrain vehicle 100 are conveniently improved, and the driving comfort and the interestingness of a driver are further improved. In addition, through the arrangement, the cost of the all-terrain vehicle 100 can be saved under the condition that the power requirement of the all-terrain vehicle 100 is met, and the resource utilization rate of the all-terrain vehicle 100 is improved.

As shown in fig. 4-6, as one implementation, the all-terrain vehicle 100 includes a first mode of operation, a second mode of operation, and a third mode of operation. Wherein the solid lines with arrows in fig. 4 to 6 represent the directions of actual power transmission; the dashed lines with arrows in fig. 4 and 5 indicate the directions in which power can be transmitted, but in fig. 4 and 5, actual power is not transmitted. As shown in fig. 4, when the ATV 100 is in the first mode of operation, the power battery 153 provides power to the drive motor 151. As shown in fig. 5, range extender assembly 152 provides power to drive motor 151 when all-terrain vehicle 100 is in the second mode of operation. As shown in fig. 6, when the all-terrain vehicle 100 is in the third mode of operation, the power battery 153 and the motor Cheng Qizong-152 cooperate to provide power to the drive motor 151. Through the arrangement, the all-terrain vehicle 100 can adopt different power supply modes under different road conditions, so that the output power of the driving motor 151 is changed, the power requirements of the all-terrain vehicle 100 under different conditions are met, and the power performance of the all-terrain vehicle 100 is improved. The first operation mode may be an operation mode when the power required by the all-terrain vehicle 100 is not high in a case where the road is relatively flat. The second operation mode may be an operation mode when the power battery 153 is insufficient to maintain the operation of the driving motor 151 for a long time when the ATV 100 is stopped. The third mode of operation may be a mode of operation when the road conditions are relatively complex or the ATV 100 needs to be derated, and the ATV 100 needs strong power. It will be appreciated that the first, second and third modes of operation may also be adjusted according to the driver's demand for power. Namely, the driver can switch among the first operation mode, the second operation mode and the third operation mode according to the self requirement, so that the driving comfort and the interestingness of the driver are improved. Further, the ATV 100 may also automatically switch among the first operation mode, the second operation mode and the third operation mode according to road conditions, so as to implement the driving assistance function of the ATV 100.

As one implementation, when all-terrain vehicle 100 is in the first mode of operation, the output power of drive motor 151 is a first power; when ATV 100 is in the second mode of operation, the output power of drive motor 151 is a second power; when ATV 100 is in the third mode of operation, the output power of drive motor 151 is a third power. Wherein the first power is less than the second power, and the second power is less than the third power. Through the arrangement, the output power of the driving motor 151 can be changed when the all-terrain vehicle 100 is under different road conditions, so that the power requirement of the all-terrain vehicle 100 under different conditions is met, the off-road capability, the escaping capability and the power performance of the all-terrain vehicle 100 are conveniently improved, and the driving comfort and the interestingness of a driver are further improved.

As shown in fig. 3, as one implementation, the transmission assembly 17 includes a transmission shaft 171, where the transmission shaft 171 at least partially connects the drive motor 151 and the first traveling wheel 131, such that the drive motor 151 drives the transmission shaft 171 and, in turn, the first traveling wheel 131. Drive axle 171 extends substantially in the fore-aft direction of ATV 100. The drive shaft 171 is at least partially disposed between the first travel wheel 131 and the second travel wheel 132. 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.

With the above arrangement, the driving force of the driving motor 151 can be transmitted to the first traveling wheel 131 through the front axle mechanism 172, the transmission shaft 171, thereby driving the first traveling wheel 131; the second traveling wheel 132 may be directly driven by the driving motor 151, thereby realizing the four-wheel driving of the all-terrain vehicle 100.

As shown in fig. 2 and 7, as one implementation, the driving motor 151 includes a first motor 1511 and a second motor 1512, at which time there is no need to provide a transmission shaft 171. Specifically, the first motor 1511 is connected to the range extender assembly 152 and the power battery 153, respectively, and the second motor 1512 is connected to the power battery 153.

The second motor 1512 is disposed at the front 111 of the frame 11, and the second motor 1512 is at least partially disposed between the first front wheel 1311 and the second front wheel 1312. In fig. 7, the solid line with an arrow indicates the direction of power transmission, that is, power is transmitted from the power battery 153 to the first motor 1511 and power is transmitted from the power battery 153 to the second motor 1512 by the power generator Cheng Qizong to 152. Through the arrangement, the structure of the transmission shaft 171 can be omitted, so that the structure of the transmission assembly 17 is simplified, the arrangement space of the all-terrain vehicle 100 is saved, the installation of other parts of the all-terrain vehicle 100 can be facilitated, and the assembly performance of the all-terrain vehicle 100 is improved. In addition, the second travelling wheel 132 is driven by the first motor 1511, and the first travelling wheel 131 is driven by the second motor 1512, so that the driving modes of the first travelling wheel 131 and the second travelling wheel 132 can be set independently of each other, the use of the other motor is not affected when the first motor 1511 or the second motor 1512 fails, and the independence of the driving motor 151 and the safety of the all-terrain vehicle 100 are improved.

The body controller 21 is provided at the rear portion 112 of the frame 11, and the motor controller 154 is also provided at the rear portion 112 of the frame 11. Specifically, the body controller 21 may be disposed at one side of the symmetry plane 101, and the motor controller 154 may be disposed at the other side of the symmetry plane 101. That is, body controller 21 and motor controller 154 may be disposed on both sides of ATV 100, respectively. It will be appreciated that the body controller 21 may be disposed on one side of the plane of symmetry 101, and that the motor controller 154 may be disposed on the side of the plane of symmetry 101 on which the body controller 21 is disposed. I.e., body controller 21 and motor controller 154 may be disposed on the same side of ATV 100. By the arrangement, the arrangement mode of the vehicle body controller 21 and the motor controller 154 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.

Specifically, the power supply assembly 22 includes a current converter, a charger, and an interface. The current converter, charger and interface are all connected to the power battery 153. The current converter is used for converting the direct current of the power battery 153 into alternating current. The charger is used to charge the power battery 153.
