Specifically, in the technical solution of the present invention, when the signal collection module 3 obtains a parking instruction and does not obtain vehicle speed information, the controller module controls the brake motor 2 not to be activated, so the brake 11 is not activated. When the signal collection module 3 obtains a parking instruction and vehicle speed information, wherein the vehicle speed v is greater than 20km/h, the controller module controls the brake motor 2 to start, and the brake 11 brakes to decelerate the vehicle to stop. When the signal collection module 3 does not obtain the parking instruction and the vehicle speed information, the controller module controls the brake motor 2 not to be started, so the brake 11 is not started. When the signal collection module 3 obtains the vehicle speed information, wherein the vehicle speed v is more than 20km/h, and a parking instruction is not obtained, the controller module controls the brake motor 2 not to be started, so that the brake 11 is not started. When the signal collection module 3 obtains the vehicle speed information and the parking instruction, wherein the vehicle speed v is less than or equal to 20km/h, the controller module controls the brake motor 2 not to be started, so the brake 11 is not started. When the signal collection module 3 obtains the vehicle speed information, wherein the vehicle speed v is less than or equal to 20km/h, and a parking instruction is not obtained, the controller module controls the brake motor 2 not to be started, so the brake 11 is not started.

Further, the transmission mechanism 13 includes a transmission member 131, a pressing pull rod 132 and a pressing push rod 133, the transmission member 131 is disposed along the axial extension of the brake disc 12, the transmission member 131 is provided with an external thread and is drivingly connected to the output shaft of the brake motor 2, the pressing pull rod 132 is disposed along the axial extension of the brake disc 12, one end of the pressing pull rod 132 is provided for installing the first friction plate 111, the other end of the pressing pull rod 132 is installed at one end of the transmission member 131 far away from the friction plate set 11, the pressing push rod 133 is disposed along the axial extension of the brake disc 12, a threaded hole matched with the first external thread is formed, the threaded hole is in threaded connection with the first external thread, and one end of the pressing push rod 133 is provided for installing the second friction plate 112.

In the above implementation manner, the brake motor 2 drives the transmission member 131 to rotate, because the threaded hole is in threaded connection with the first external thread, the transmission member 131 and the pressing push rod 133 move in opposite directions along the axial direction of the brake disc 12, and because the pressing pull rod 132 is mounted to the transmission member 131, the first friction plate 111 mounted to the pressing pull rod 132 and the second friction plate 112 mounted to the pressing push rod 133 move in opposite directions, so that the first friction plate 111 and the second friction plate 112 are driven to approach or move away from each other to clamp or loosen the brake disc 12, so that the structure is simple and easy to operate.

In order to effectively connect the brake motor 2 and the transmission member 131 in a driving manner, the transmission mechanism 13 further includes a connecting member 134, the connecting member 134 is disposed between the output shaft of the brake motor 2 and the transmission member 131, wherein the connecting member 134 is connected with the transmission member 131 through a spline, and thus, the structure is simple.

In order to prevent the pressing push rod 133 from moving too far away from the friction plate set 11, the transmission piece 131 is provided with a limiting protrusion 1311, the limiting protrusion 1311 is used for abutting against one end, away from the friction plate set 11, of the pressing push rod 133, and thus, the movement stroke of the pressing push rod 133 towards the direction away from the friction plate set 11 is limited, so that the pressing push rod 133 can rapidly push the second friction plate 112 to abut against the brake disc 12 to realize braking.
