Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0037] In this application, the terms "calculate", "judge", "control", "determine", "identify", etc. refer to the operation and process of a computer system or similar electronic computing device (e.g., a controller, a processor, etc.). The following describes an electric all-terrain vehicle according to an embodiment of the present application in conjunction with the accompanying drawings.

[0038] like Figure 1 As shown, the present application proposes an electric all-terrain vehicle 10, which uses batteries as power, has low cost, is more environmentally friendly, and does not require frequent replacement of parts, thereby reducing maintenance costs. In the related art, all-terrain vehicles (UTV, Utility Vehicle) include four-wheel all-terrain vehicles (ATV, All Terrain Vehicle), multi-purpose all-terrain vehicles and recreational field vehicles.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the electric all-terrain vehicle 10 may include a frame 100, a seat 120 and a carriage 300. The frame 100 may be a symmetrical structure, including at least two cross beams and at least two longitudinal beams. The seat 120 is for the user to sit on, and is mounted to the frame 100. The carriage 300 is arranged on the frame 100, and the carriage 300 may be located behind the seat 120. The electric all-terrain vehicle 10 also includes a front wheel 40F and a rear wheel 40R. The front wheel 40F and the rear wheel 40R may also be defined as the running wheels of the electric all-terrain vehicle 10, and the front wheel 40F and the rear wheel 40R together constitute a running wheel set 400. The running wheel set 400 may also include a first differential that enables the two front wheels to rotate at different speeds; and a second differential that enables the two rear wheels to rotate at different speeds. In one embodiment, the rear wheel 40R may provide driving force for the electric all-terrain vehicle 10. In one embodiment, the front wheel 40F and the rear wheel 40R jointly provide driving force for the electric all-terrain vehicle 10. The carriage 300 is arranged above the rear wheel 40R. The carriage 300 can be used to carry objects, such as carrying a weight of 260-460 kg. The electric all-terrain vehicle 10 also includes a suspension assembly 111, which is arranged between the frame 100 and the running wheel group 400, and is used to dynamically connect the frame 100 and the running wheel group 400, to provide shock absorption and damping effects for the whole machine, and reduce the user's bumps.

[0040] In this embodiment, the electric all-terrain vehicle 10 includes a steering wheel 501. The steering wheel 501 can be located in front of the seat 120. The steering wheel 501 is connected to the steering gear, and the steering gear is driven by rotating the steering wheel 501, and the steering gear pulls the steering knuckle of the front wheel 40F to rotate, thereby changing the travel direction of the electric all-terrain vehicle 10. In addition to the steering wheel, the operating component 500 of the electric all-terrain vehicle 10 also includes a control panel 511, an accelerator pedal 521, a brake pedal 541 and a parking component. In some embodiments, the parking component includes a parking pedal. In other embodiments, the parking component includes a parking handle or a parking button. The electric all-terrain vehicle 10 may also include a display screen 531 for displaying various types of information of the electric all-terrain vehicle 10, such as cruising range, driving mode, etc.

[0041] A front bumper 102 is provided in front of the frame 100, and the front bumper 102 can protect the electric all-terrain vehicle 10. In addition, a towing structure is provided in front of the frame 100, and when the electric all-terrain vehicle 10 is stuck in a muddy area, a fixed object can be towed to make the electric all-terrain vehicle 10 escape from the muddy area. In some embodiments, the towing structure also includes a winch motor. Optionally, a towing connection is provided at the rear of the frame 100, and the towing connection can tow heavy objects, for example, a weight of 200-400 kg. Optionally, the towing connection can tow a wheeled power tool.

[0042] See also Figure 2 As shown, the electric all-terrain vehicle 10 also includes a drive system 12. In some embodiments, the drive system 12 includes two drive motors 123, which are used to drive the front and rear running wheels respectively. The electric all-terrain vehicle 10 also includes a power supply assembly 161, which includes an energy storage device to provide power to various components of the electric all-terrain vehicle 10, at least to provide power to the drive system. In some embodiments, the power supply assembly 161 is composed of a detachable battery pack. In some embodiments, the power supply assembly 161 is composed of a non-detachable built-in battery module. In some embodiments, the power supply assembly 161 is composed of a detachable battery pack and a non-detachable built-in battery module. In some embodiments, the power supply assembly is a DC power supply.

[0043] In some embodiments, Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the suspension assembly 111 is connected to the running wheel set 400 through the support 114. The suspension assembly 111 includes an upper fork arm 1111 and a lower fork arm 1112. The upper fork arm 1111 is connected to the support 114 through the first steering knuckle 112, and the lower fork arm 1112 is connected to the support 114 through the second steering knuckle 113. The support 114 is connected to the running wheel, so that the suspension assembly 111 dynamically connects the frame 100 and the running wheel set 400, providing shock absorption and damping effects for the whole vehicle to reduce bumps. The plane perpendicular to the front and rear directions is defined as the first reference plane, and the line connecting the center of the first steering knuckle 112 and the center of the second steering knuckle 113 is the first straight line L1. The projection line of the first straight line L1 on the first reference plane and the projection line of the wheel center line K on the first reference plane form a first angle α, i.e., the inclination angle. The inclination angle mainly affects the low-speed self-centering effect. Among them, the value range of the first angle α is greater than or equal to 10° and less than or equal to 20°. In some embodiments, the value range of the first angle α is greater than or equal to 10° and less than or equal to 15°. In the related art, the inclination angle is about 7°, 8° or 9° to avoid heavy steering, but there is a risk of being unable to return to the center. By limiting the angle range of the inclination angle to be greater than or equal to 10° and less than or equal to 20°, the return effect of the electric all-terrain vehicle 10 when driving at a low speed is guaranteed, and the inclination angle is too small to cause the inability to return to the center, and the inclination angle is too large to cause heavy steering. The specific value of the first angle α can be 10°, 12°, 14°, 16°, 18° and 20°, etc., without limitation. Optionally, the distance between the first steering knuckle 112 and the wheel centerline K is greater than the distance between the second steering knuckle 113 and the wheel centerline K.

[0044] like Fig.10 and Fig.11 As shown, the electric all-terrain vehicle 10 further includes an electronic power steering system 95, which is used to provide steering force for the running wheel set 400. As the inclination angle increases, the steering becomes heavy, and the electronic power steering system 95 provides auxiliary steering force to the running wheel set 400, so that the electric all-terrain vehicle 10 in the related art can improve the self-centering effect as much as possible while keeping other structures unchanged after increasing the inclination angle, greatly reduce the steering resistance, and is not easy to cause driving fatigue.

[0045] The electric all-terrain vehicle 10 is usually driven at a medium or low speed, so the inclination angle is very important. However, the electric all-terrain vehicle 10 may also be driven at a high speed. Therefore, a plane perpendicular to the left and right directions is defined as the second reference plane, such as Figure 6As shown, the line connecting the center of the first steering knuckle 112 and the center of the second steering knuckle 113 is the first straight line L1, and the projection line of the first straight line L1 on the second reference plane and the projection line of the wheel center line K on the second reference plane form a second angle β, i.e., the camber angle, and the camber angle mainly affects the high-speed self-centering effect. Among them, the value range of the second angle β is greater than or equal to 2° and less than or equal to 10°. By limiting the angle range of the camber angle to greater than or equal to 2° and less than or equal to 10°, the self-centering effect of the electric all-terrain vehicle 10 when driving at high speed is guaranteed. The specific value of the second angle β can be 2°, 4°, 6°, 8°, 10°, etc., without limitation.

[0046] In some embodiments, the value range of the second angle β is greater than or equal to 4° and less than or equal to 8°. By limiting the camber angle to a larger angle range, the self-centering effect of the electric all-terrain vehicle 10 when driving at high speed is further ensured. Optionally, the specific value of the second angle β can be 4°, 5°, 6°, 7°, 8°, etc., without limitation.

[0047] like Figure 2 and Figure 4 As shown, the upper fork arm 1111 and the lower fork arm 1112 are both composed of a triangular fork arm rod, which includes a rotating shaft 111A and two connecting rods 111B connected to the rotating shaft 111A. The connection between the two connecting rods 111B is connected to the support 114. The rotating shaft 111A is rotatably connected to the frame 100, so that the frame 100 and the support 114 and the running wheel group 400 connected to the support 114 can rotate relative to each other, thereby realizing a dynamic connection between the frame 100 and the running wheel group 400. Similarly, in other embodiments, the fork arm includes a rotating shaft 111A and two connecting rods 111B connected to the rotating shaft 111A, and the connection between the two connecting rods 111B is connected to the support 114, wherein the connecting rod 111B and the rotating shaft 111A are rotatably connected, and the rotating shaft 111A and the frame 100 are fixedly connected, and the two connecting rods 111B can also rotate relative to the frame 100. It can be set according to actual needs without limitation.

[0048] like Figure 4 As shown, the rotation axis 111A extends along the second straight line L2, and the projection line of the second straight line L2 on the second reference plane and the projection line of the horizontal plane on the second reference plane form a third angle γ, wherein the second reference plane is perpendicular to the left and right directions, and the value range of the third angle γ is greater than or equal to 4° and less than or equal to 7°. By slightly tilting the rotation axis 111A relative to the horizontal plane, the fork arm rod is slightly tilted, so that the support 114 connected to the fork arm rod and the walking wheel connected to the support 114 are slightly tilted. Optionally, the rotation axis 111A can be tilted downward or upward. The specific value of the third angle γ can be 4°, 5°, 6°, 7°, etc., without limitation.

[0049] like Figure 1 As shown, the energy storage device includes at least one battery pack 161, the driving assembly includes at least a motor, and the battery pack 161 is at least used to power the motor, that is, the battery pack 161 powers the DC motor, and the DC motor drives the running wheel to rotate, which is simple to control.

[0050] In some embodiments, Figure 4 and Figure 7 As shown, the suspension assembly 111 includes an upper fork arm 1111, a lower fork arm 1112 and a shock absorber, and the upper fork arm 1111 and the lower fork arm 1112 are both composed of a fork arm rod. A first connection point 111C, a second connection point 111D and a third connection point 111E are provided on the fork arm. The fork arm is connected to the walking wheel set 400 through the first connection point 111C, and is connected to the frame 100 through the second connection point 111D and the third connection point 111E. The line connecting the first connection point 111C and the second connection point 111D and the line connecting the first connection point 111C and the third connection point 111E form a first angle a, the line connecting the second connection point 111D and the first connection point 111C and the line connecting the second connection point 111D and the third connection point 111E form a second angle b, the line connecting the third connection point 111E and the first connection point 111C and the line connecting the third connection point 111E and the second connection point 111D form a third angle c, and the third angle c is close to the steering gear and is the largest. By increasing the third angle c, the installation space between the line connecting the third connection point 111E and the first connection point 111C and the line connecting the third connection point 111E and the second connection point 111D is increased, so that structural interference between the fork arm and the steering gear can be prevented.

[0051] Alternatively, if Figure 7 As shown, the first connecting rod 111B is located on the line connecting the first connecting point 111C and the third connecting point 111E, the second connecting rod 111B is located on the line connecting the first connecting point 111C and the second connecting point 111D, the rotation axis 111A is located on the line connecting the second connecting point 111D and the third connecting point 111E, the angle between the first connecting rod 111B and the rotation axis 111A is the third angle c, the angle between the second connecting rod 111B and the rotation axis 111A is the second angle b, and the angle between the first connecting rod 111B and the second connecting rod 111B is the first angle a.

[0052] The first angle a is the smallest, and the distance between the connecting line of the second connection point 111D and the third connection point 111E and the first connection point 111C is maximized to further reduce the risk of structural interference between the fork arm and the steering gear. The first angle a is an acute angle, and the third angle c can be an acute angle, a right angle, or an obtuse angle, without limitation.

[0053] On the horizontal projection plane, a closed figure formed by the connecting line of the first connection point 111C, the second connection point 111D and the third connection point 111E or the extended line of the connecting line is on the same side of the connecting line of the centers of the two running wheels, where the two running wheels refer to the two front wheels 40F or the two rear wheels 40R.

[0054] Alternatively, if Figure 2 and Figure 7 As shown, a closed figure formed by the connecting line of the first connection point 111C, the second connection point 111D and the third connection point 111E or the extended lines of the connecting lines is on the side of the center line of the two front wheels 40F facing the outer side of the vehicle body, and a closed figure formed by the connecting line of the first connection point 111C, the second connection point 111D and the third connection point 111E or the extended lines of the connecting lines is on the side of the center line of the two rear wheels 40R facing the outer side of the vehicle body. The distance between the center line of the two front wheels 40F and the center line of the two rear wheels 40R is increased as much as possible to increase the installation space in the middle and facilitate the subsequent installation layout of other structures.

[0055] Optionally, a closed figure formed by the connecting line of the first connection point 111C, the second connection point 111D and the third connection point 111E or the extended lines of the connecting lines is on the side of the center line of the two front wheels 40F facing the inner side of the vehicle body, and a closed figure formed by the connecting line of the first connection point 111C, the second connection point 111D and the third connection point 111E or the extended lines of the connecting lines is on the side of the center line of the two rear wheels 40R facing the outer side of the vehicle body, so as to minimize the distance between the center line of the two front wheels 40F and the center line of the two rear wheels 40R to make the structure more compact.

[0056] Optionally, the closed figure formed by the line connecting the first connection point 111C, the second connection point 111D and the third connection point 111E or the extended line of the line is on the side of the line connecting the centers of the two front wheels 40F facing the inner side of the vehicle body, and the closed figure formed by the line connecting the first connection point 111C, the second connection point 111D and the third connection point 111E or the extended line of the line is on the side of the line connecting the centers of the two rear wheels 40R facing the outer side of the vehicle body. Alternatively, the closed figure formed by the line connecting the first connection point 111C, the second connection point 111D and the third connection point 111E or the extended line of the line is on the side of the line connecting the centers of the two front wheels 40F facing the outer side of the vehicle body, and the closed figure formed by the line connecting the first connection point 111C, the second connection point 111D and the third connection point 111E or the extended line of the line is on the side of the line connecting the centers of the two rear wheels 40R facing the inner side of the vehicle body. The setting can be made according to the needs without limitation.

[0057] The size of the fork arm rod of the upper fork arm 1111 is different from that of the fork arm rod of the lower fork arm 1112. The connection point between the upper fork arm 1111 and the lower fork arm 1112 is hinged, so that the two can rotate relative to each other to increase the degree of freedom between the upper fork arm 1111 and the lower fork arm 1112.

[0058] The projection area of ​​the upper fork arm 1111 on the horizontal projection plane is not greater than the projection area of ​​the lower fork arm 1112 on the horizontal projection plane, which lowers the center of gravity position of the connection structure of the upper fork arm 1111 and the lower fork arm 1112 and makes the structure more stable.

[0059] The energy storage device includes at least one battery pack 161 to provide a DC power supply with a stable output for easy use. For example, the battery pack 161 is used to power the control panel 511, the display screen 531, etc. For example, the walking wheel is driven by a DC motor, and the battery pack 161 is used to power the DC motor.

[0060] In some embodiments, the suspension assembly 111 is disposed between the frame 100 and the running wheel assembly 400. The suspension assembly 111 includes a shock absorber with a sensor. The sensor is used to collect vehicle condition and road condition information of the electric all-terrain vehicle 10. The electric all-terrain vehicle 10 also includes a signal processor and a control unit to adjust the damping of the shock absorber according to the vehicle condition and road condition information collected by the sensor. Among them, the sensor includes at least one of an acceleration sensor and a force sensor. The vehicle condition information includes information such as vehicle speed, lateral acceleration, steering wheel 501 angle and vehicle body height. Working conditions include turning, acceleration, braking and vacating. The damping adjustment method of the shock absorber in the prior art can be manual, electric or automatic. Its specific structure and control form can refer to the prior art and will not be repeated.

[0061] The suspension assembly 111 further includes a fork arm rod, which connects the frame 100 and the running wheel set 400 . The shock absorber has a first end and a second end, wherein the first end is connected to the frame 100 and the second end is connected to the fork arm rod.

[0062] Optionally, the shock absorber is an electronic shock absorber.

[0063] like Figure 8 As shown, the drive system 12 of the electric all-terrain vehicle 10 includes at least a front drive motor 123F. The front drive system 12F includes a front drive motor 123F, a front controller 124F and a front drive circuit 125F. The front drive system 12F drives the front wheel 40F to travel. Optionally, the output shaft of the front drive motor 123F is connected to a front transmission assembly 127F to drive the front wheel 40F to rotate. Optionally, the front drive motor 123F is a permanent magnet synchronous motor or an asynchronous motor.

[0064] In some embodiments, Figure 2 As shown, the projection of the drive motor 123 on the first plane is at least partially located between the projection of the upper fork arm 1111 on the first plane and the projection of the lower fork arm 1112 on the first plane, and the first plane is perpendicular to the left and right directions, so as to prevent the drive motor 123 from structurally interfering with the upper fork arm 1111 and the lower fork arm 1112 in the front-rear direction of the vehicle body.

[0065] Alternatively, if Figure 3 As shown, the drive motor 123 is placed horizontally. The electric all-terrain vehicle 10 also includes a steering gear, which is parallel to the drive motor 123. The electric all-terrain vehicle 10 also includes a gear box 13, which is connected between the drive system 12 and the walking wheel set 400, and the gear box 13 is parallel to the drive motor 123. By arranging the drive motor 123, the steering gear and the gear box 13 in the above manner, the space occupied by the motor shaft of the drive motor 123 along the length direction is reduced, making the structure more compact. Optionally, the drive motor 123 is arranged in front of the seat 120, making full use of the space in front of the seat 120, and facilitating the subsequent maintenance of the drive motor 123.

In some embodiments, when the voltage of the inverter 700 reaches at least 70% of the rated voltage, the inverter 700 outputs power to the outside.
