When the motor stops running and the first turntable is fixed, the motor rotor does not completely stop due to the existence of inertia. The motor rotor will drive the second turntable and the rubber ball to rotate. Under the squeezing of the arc-shaped groove, the rubber ball will deform and break away from the arc-shaped groove and enter another arc-shaped groove, completing the inertia consumption of the second turntable and the motor rotor, so that the second turntable and the motor rotor no longer rotate, thereby achieving the protection effect of the motor and improving the service life of the motor.

The threaded hole 8 can be threadedly connected to an external fixing screw to increase the connection method between the motor and the outside, the first turntable 10 and the second turntable 11 are connected by a soft connection structure, a plurality of evenly distributed card slots 14 are opened on the circumferential outer wall of the first turntable 10, and a placement box is fixed to the top outer wall of the fixed shell 3 by bolts. 9. A card block 16 is slidably connected to the placement box 9, and one end of the card block 16 is inserted into the partial card slot 14. A power mechanism for driving the card block 16 to move is provided in the placement box 9. When in use, the motor is installed on one side of the electric pedal, and the output shaft 7 is connected to the adjustment part of the pedal. The motor is started and the card block 16 and the card slot 14 are split through the power mechanism. The motor will drive the first turntable 10 and the second turntable 11 to rotate, thereby realizing the adjustment of the motor-driven pedal. When the motor stops, the power mechanism will drive the card block 16 to insert into the card slot 14, fix the first turntable 10, and thus fix the output shaft 7, to avoid damage to the connection between the two due to the inertia of the motor driving the output shaft 7 to rotate, thereby improving the service life of the electric pedal.

[0024] Among them, the power mechanism includes an electromagnet 18, which is fixed to the top inner wall of the placement box 9 by bolts, and a magnetic block 20 is fixed to the top of the card block 16 by bolts, and the electromagnet 18 and the magnetic block 20 can be adsorbed, and the electromagnet 18 is electrically connected to the controller of the motor so that when the motor is started, the electromagnet 18 is also energized to generate magnetic force, that is, when the motor is started, the electromagnet 18 generates magnetic force, and two arc-shaped elastic plates 19 are bonded to the top of the magnetic block 20, and two fixed blocks 17 are fixed to the top inner wall of the placement box 9 by bolts, and the arc-shaped elastic plate 19 can be When in contact with the fixed block 17, the electromagnet 18 generates a magnetic force that will attract the magnetic block 20 to move upward, thereby driving the card block 16 to move upward, and then the card block 16 is disconnected from the card slot 14. The upward movement of the magnetic block 20 will squeeze the arc-shaped elastic plate 19 to deform and generate elastic force. When the motor stops, the electromagnet 18 stops supplying power and the electromagnet 18 has no magnetic force. At this time, the deformed arc-shaped elastic plate 19 will squeeze the magnetic block 20 to move downward, thereby inserting the card block 16 into the card slot 14, completing the limit of the output shaft 7, and thus achieving the protection effect of the electric pedal.

[0025] Among them, the soft connection structure includes a plurality of mounting grooves 13, and the plurality of mounting grooves 13 are all opened on one side of the second turntable 11. The plurality of mounting grooves 13 are bonded with rubber balls 12. A plurality of arc-shaped grooves 15 are opened on one side of the first turntable 10, and the rubber balls 12 are located in the arc-shaped grooves 15. During the operation of the motor, the motor rotor will drive the second turntable 11 to rotate. The second turntable 11 drives the first turntable 10 to rotate through the cooperation of the rubber balls 12 and the arc-shaped grooves 15, thereby driving the rotation of the output shaft 7. When the motor stops running and the first turntable 10 is fixed, the motor rotates Due to the existence of inertia, the motor has not completely stopped at this time. The motor rotor will drive the second turntable 11 to rotate, thereby driving the rubber ball 12 to rotate. Under the pressure of the arc-shaped groove 15, the rubber ball 12 will deform and break away from the arc-shaped groove 15, allowing the second turntable 11 to continue to rotate. When the rubber ball 12 is located at the other arc-shaped groove 15, the rubber ball 12 will enter the other arc-shaped groove 15, completing the inertia consumption of the second turntable 11 and the motor rotor, so that the second turntable 11 and the motor rotor no longer rotate, thereby achieving the protection effect of the motor and increasing the service life of the motor.

[0026] Among them, a baffle 4 is fixed to the outer wall of one side of the fixed shell 3 by bolts, and mounting holes 6 are opened at the four corners of the baffle 4, and the mounting holes 6 match the positions of the fixing holes of the shell 1. A plurality of connecting pipes 2 are provided between the baffle 4 and the shell 1, and the connecting pipes 2 are connected with the mounting holes 6 and the fixing holes. The bolts are passed through the fixing holes, the connecting pipes 2, the mounting holes 6 and the motor mounting position of the electric pedal to complete the installation of the motor. At the same time, the fixed shell 3 is avoided from being subjected to force, making the operation of the motor more stable. Washers 5 are bonded to the four corners of the baffle 4, and the washers 5 match the positions of the mounting holes 6. The washers 5 can eliminate the influence of the loosening of the bolts caused by vibration generated when the motor is running or the vehicle is driving, making the fixation of the motor more stable.

[0027] The working principle of the present utility model is as follows: when in use, the bolts are passed through the fixing holes, the connecting tube 2, the mounting holes 6 and the motor mounting part of the electric pedal to complete the installation of the motor, and the output shaft 7 is connected to the adjustment part of the pedal. When the motor is started, the electromagnet 18 is also energized to generate magnetic force. The magnetic force generated by the electromagnet 18 will attract the magnetic block 20 to move upward, thereby driving the card block 16 to move upward, and then the card block 16 is disengaged from the card slot 14. The motor will drive the first turntable 10 and the second turntable 11 to rotate, thereby realizing the adjustment of the pedal driven by the motor. When the motor stops, the electromagnet 18 stops supplying power, and the electromagnet 18 has no magnetic force. At this time, the deformed arc-shaped elastic plate 19 will squeeze the magnetic block 20 to move downward, thereby causing the card block 16 to be inserted into the card slot 14, completing the limit of the output shaft 7, and preventing the motor from driving the output shaft 7 to rotate due to inertia and causing damage to the connection between the two.
