the controller is electrically connected with the control motor 15, and a first control button, a second control button and a third control button which are electrically connected with the controller are respectively arranged on the control panel.
In this embodiment, preferably, the planetary gear transmission mechanism includes a planetary carrier fixedly disposed on the first output shaft 4 or the second output shaft 5, a planetary gear rotatably disposed on the planetary carrier and meshed with the output gear 7, and a transmission member 6 rotatably disposed on the rotor 1, the transmission member 6 has an inner gear ring meshed with the planetary gear, the transmission member 6 is connected with the differential gear structure through a transmission member, the differential gear structure includes a first differential gear shaft 11 and a second differential gear shaft 12 rotatably disposed, a first differential gear 13 fixedly disposed on the first differential gear shaft 11, a second differential gear 14 fixedly disposed on the second differential gear shaft 12 and meshed with the first differential gear 13, and the first differential gear shaft 11 and the second differential gear shaft 12 are respectively connected with the transmission member 6 on the corresponding side through the transmission member.
Wherein when the first control button is pressed, the controller sends a signal for stopping working to the control motor 15, when the second control button is pressed, the controller sends a signal for forward rotation to the control motor 15, and when the third control button is pressed, the controller sends a signal for reverse rotation to the control motor 15.
When the old person presses the first control button, the control motor stops working and the driving motor normally works, at the moment, the differential gear structure and the transmission part do not act, the electric vehicle keeps straight running at a constant speed, when the electric vehicle needs to perform in-situ forward turning, the second control button is pressed, the control motor rotates positively, at the moment, the speed of an output shaft at one side becomes zero by utilizing the cooperation of the connecting component, the transmission part and the second gear, the speed of an output shaft at the other side is accelerated, forward turning is realized, the third control button is pressed when reverse turning, the principle is similar, the driving motor can stop working state when the second control button and the third control button are pressed, in-situ turning is realized under the working state, and when the driving motor has output, the realized action is wheel steering movement.
The working principle of the transmission structure is as follows: when the first output shaft 4 and the second output shaft 5 move at the same speed, the first output shaft 4 and the second output shaft 5 are at the same speed with the rotor 1, the second gear 9 and the transmission member 6 with the inner gear ring meshed with the second gear 9 are relatively stationary, so that the differential gear structure is also in a stationary state, when the differential speed is generated, if the speed of the first output shaft 4 is reduced and is smaller than that of the rotor 1, the first gear 9 on the first output shaft 4 side rotates reversely relative to the rotor 1 when the vehicle turns or one wheel of the vehicle encounters an obstacle, thereby driving the transmission member 6 on the first output shaft 4 side to rotate reversely relative to the rotor 1, and after the differential gear structure is adopted, the transmission member 6 on the second output shaft 5 side rotates in the same direction relative to the rotor 1 and is transmitted to the second gear 9 on the second output shaft 5, so that the rotating speed of the second output shaft 5 is increased, and the rotating speed of the wheel on the outer side of the corner can be accelerated when the vehicle turns.
In the aspect of motor differential control, the differential gear structure is controlled by the control motor 15, when the speed is uniform, the control motor 15 does not work, as the rotation speed of the rotor is the same as that of the first output shaft 4 and the second output shaft 5, the transmission member 6 and the differential gear structure do not act, when steering is needed, the control motor 15 rotates positively to drive the differential gear structure to act, namely, one side transmission member rotates positively, the other side transmission member 6 rotates reversely, so that the first gears 9 on two sides are driven to rotate positively and reversely, one side of the output shafts on two sides is in speed limiting and the other side of the output shafts on two sides is in speed increasing, thus differential occurs, and one side with higher speed is the outer side of steering, and stable steering is realized.

In this embodiment, preferably, the transmission member 6 is rotatably connected with the rotor 1 through a rotating bearing respectively, so as to reduce the occupied volume, a hole through which the rotor 1 passes is formed in one end surface of the transmission member 6, a cavity is formed in the other end surface of the transmission member, and the ring gear is disposed on one side of the cavity, and the other side of the cavity is a mounting cavity of the rotating bearing, so that the ring gear and the ring gear on the transmission member 6 are not affected, and the mounting volume is reduced.
For the convenience of processing, the output gear 7 and the rotor 1 are integrally formed, and the output gear 7 section on the rotor 1 can be mechanically processed, or can be integrally formed by die forging, etc., instead of assembling, so that the coaxiality is ensured, the process steps are reduced, and the strength is ensured.
