Detailed Description

The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention.

As shown in fig. 1 and 2, a damping driving mechanism includes a frame body 1, a high-speed outer rotor dc motor 2, and a lifting plate 15 fixedly disposed at the bottom of the high-speed outer rotor dc motor 2; the four vertex angles of the hoisting plate 15 are provided with damping rubber pads, the tops of the damping rubber pads are fixedly connected with the frame body 1 through the hanging rods 16, and reinforcing rib plates 17 are arranged between the hanging rods 16 and the frame body 1. A damping rubber pad is arranged between the hanging rod and the hoisting plate, and the damping rubber pad can buffer the vibration generated in the operation process of the high-speed outer rotor direct current motor and avoid influencing the structure of the whole device. The reinforcing rib plate can stabilize the connection of the suspender and the frame body and prevent the suspender from shaking.

The shock absorption rubber mat comprises a fixing plate 18 fixedly connected with the hoisting plate 15, a cylindrical platform 19 arranged on the fixing plate 18 and a step platform 20 arranged on the cylindrical platform 19, and the top of the step platform 20 is fixedly connected with the suspender 16. The fixed plate is used for the installation of shock attenuation cushion and fixed plate, and the cylindricality platform can guarantee that the shock attenuation cushion has sufficient intensity, and the ladder platform can provide better shock attenuation effect, for the intensity of further improvement shock attenuation cushion, the shock attenuation cushion is rubber material integrated into one piece.

As shown in fig. 3, the stepping motor further comprises a bottom plate 3, a first end plate 4 and a second end plate 5 which are arranged at two ends of the bottom plate 3, a first stepping motor 6 which is arranged at the outer side of the first end plate 4, and a lead screw 7 which is fixedly connected with an output shaft of the first stepping motor 6; the screw rod 7 penetrates through the first end plate 4 and is rotationally connected with the second end plate 5; the lead screw 7 is provided with a sliding table 8, the sliding table 8 is provided with a second stepping motor 9, an output shaft of the second stepping motor 9 is provided with a synchronous belt pulley 10, and the outer side of the outer rotor of the high-speed outer rotor direct current motor 2 is provided with a synchronous belt 11 matched with the synchronous belt pulley 10. Preferably, the screw 7 is a ball screw.

The first stepping motor drives the screw rod to rotate, so that the sliding table is driven to move along the screw rod. When the device needs to output high-speed rotation, the sliding table is far away from the high-speed outer rotor direct current motor, and the high-speed outer rotor direct current motor directly outputs power. When the device needs to output low-speed rotation or rotate a certain angle, the high-speed outer rotor direct current motor stops working, the first step motor works, the sliding table is close to the direction of the high-speed outer rotor direct current motor until the synchronous belt wheel is meshed with the synchronous belt, at the moment, the second step motor starts working, the synchronous belt wheel drives the synchronous belt to rotate so as to drive the outer rotor of the high-speed outer rotor direct current motor to rotate, and the high-speed outer rotor direct current motor finishes low-speed rotation or rotates to a certain angle.
