[0024] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Embodiment 1

[0025] Please refer to Figures 1-4 The utility model provides a technical scheme:

[0026] An electronic gear shifting device comprises a gear shifting execution mechanism 1, gear shifting actuator signal lines 2 and a gearbox 3.

[0027] The gear shifting execution mechanism 1 is arranged at the gear shifting fork pin extension end of the gearbox 3, the gear shifting execution mechanism 1 is connected with two gear shifting actuator signal lines 2, the gearbox 3 transmits the speed and torque from the driving motor to the wheels after speed reduction and torque increase, wherein there are two gears, and the gear shifting actuator signal lines 2 are connected with a gear shifting switch.

[0028] The gear shifting execution mechanism 1 comprises a mounting seat 101, a sliding block 103, a gear shifting motor 111, a rocker wheel 108, a fixing screw 109 and a speed reducer 110; the mounting seat 101 is arranged with the speed reducer 110 through the fixing screw 109, and the sliding block 103, the gear shifting motor 111 and the rocker wheel 108 are arranged in the mounting seat space;

[0029] The output shaft of the reduction gearbox 110 is fixedly connected with the rocker wheel 108, and the rocker wheel 108 rotates synchronously with the output shaft of the reduction gearbox 110;

[0030] A bias hole is formed in the rocker wheel 108 for mounting the fixing bolt 106, and the fish-eye joint shaft 107 is mounted through the fixing bolt 106, wherein the fish-eye joint shaft 107 is connected with the fixing bolt 106 through a clearance fit;

[0031] The fish-eye joint shaft 107 is integrally connected with the Y-shaped joint 105 through a threaded connection, and at this time, the Y-shaped joint 105 is located at the closest position;

[0032] The Y-shaped joint 105 is connected with the I-shaped joint 112 through the fixed pin 104, and the two can rotate relative to each other;

[0033] The shaft body of the I-shaped joint 112 is inserted into the sliding block 103, so that the movement track of the I-shaped joint 112 in the axial direction is stable and reliable;

[0034] The I-shaped joint 112 is provided with a connecting nut 102 at the end, and the connecting nut 102 is used for connecting with the gear shifting fork of the gearbox 3.

[0035] Working principle:

[0036] The gear shifting switch is mounted on the steering handle of the vehicle through the fixing ring 10, and the gear shifting switch has a switch shell 5 which mainly wraps the terminal and the gear shifting spring sheet. The switch shell 5 is provided with a switch button 8, and the switch button 8 is provided with an I-gear position 6 and a II-gear position 7. The controller 9 is wrapped on the side surface by the switch shell 5. The gear shifting switch is provided with a positive power line 11 and a negative power line 12 for power supply;

[0037] After the vehicle is connected to the power supply, when the driver presses the I-gear position 6 on the gear shifting switch during driving, on one hand, the power supply signal is connected, and on the other hand, the driving intention signal of the driver is transmitted to the control board. After the control board recognizes, the signal is output to the gear shifting motor 111 of the gear shifting actuator 1. After the gear shifting motor 111 receives the signal, it starts to work and rotates. After the reduction gearbox 110 reduces the speed and increases the torque, the rocker wheel 108 rotates synchronously. The rocker wheel 108 plays the role of a rocker arm and drives the Y-shaped joint 105 to swing, thereby pulling the I-shaped joint 112 to move axially along the track in the sliding block 103, and then pulling the gear shifting fork pin in the gearbox 3 to pull out, thereby realizing gear shifting. The response time is very short (time < 1S, the specific response time is obtained by calculating the parameters and applying the program to the control board). The Y-shaped joint 112 only rotates half a circle, and at this time, the Y-shaped joint 112 moves to the side of the farthest position. At this time, the gearbox 3 is hung from the high gear to the low gear state, thereby realizing the gear shifting function;

[0038] Similarly, when the II position 7 on the gear shift switch is pressed, the motor operates, and the Y-shaped joint 112 is driven to rotate half a circle again, at this time, the Y-shaped joint 112 moves to the nearest position, at this time, the gearbox 3 is hung from the low gear to the high gear state, and the gear shifting function is realized.

[0039] The specific gear of the gearbox 3 can be judged according to the position of the button on the gear shift switch.

[0040] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
