Referring to fig. 1, a geneva drive lifter mechanism includes: the device comprises a motor 1, a base 2, a drive plate 3, a grooved pulley 4 and a rotating shaft assembly 5; the motor 1 is arranged on the base 2; the drive plate 3 is fixedly arranged on the output shaft of the motor 1; the grooved pulley 4 is in transmission connection with the drive plate 3, and the grooved pulley 4 is rotatably arranged on the rotating shaft component 5; the lower part of the base 2 is provided with a fixing lug 21, a first shaft hole is formed in the fixing lug 21, and the rotating shaft assembly 5 penetrates into the first shaft hole; the grooved wheel 4 comprises a fixed end and a free end which rotates along with the driving plate; the free end of the sheave 4 is provided with a chute 41 facing the fixed end, and the rotating shaft assembly 5 is arranged at the fixed end of the sheave 4 in a penetrating way.

In this embodiment, the complicated crank link mechanism of the conventional lifter is replaced by two parts, namely the dial 3 and the sheave 4, thereby simplifying the structure of the system and making it easier to maintain and replace the parts.

In an embodiment of the present application, a second shaft hole is formed in the middle of the driving plate 3, and the second shaft hole is fixedly connected to the output shaft of the motor 1. Therefore, the source of the rotary power of the Maltese transmission assembly is realized. The outer edge of the dial is provided with a bulge ring facing away from the motor, the bulge ring is provided with a first stop catch 32 facing away from the motor, the bulge ring is provided with a second stop catch 33 facing away from the motor, the first stop catch 32 and the second stop catch 33 are arranged on two sides of the periphery of the bulge ring, and the first stop catch 32 and the second stop catch 33 are the same in height. A round pin 31 is vertically connected to the radial bulge of the dial plate 3 back to the motor direction. The dial 3 reciprocates in the slide groove 41 of the sheave 4 by the round pin 31, thereby rotating the sheave 4. The sheave 4 is a fan-shaped structure with thickness, and comprises an arc edge and a radial edge, wherein the radial edge is a concave arc, a first straight abutting surface 42 and a second straight abutting surface 43 are arranged between the radial edge and the arc edge, and the thickness of the sheave 4 is the same as the height of the first stop 32 and the second stop 33. The surface of the first stopper 32 close to the first abutting surface 42 is provided with a first small hole (angle problem, not reflected in the figure), the first small hole is internally provided with a first distance sensor (angle problem, not reflected in the figure), the surface of the second stopper 33 close to the second abutting surface 43 is provided with a second small hole (angle problem, not reflected in the figure), and the second small hole is internally provided with a second distance sensor (angle problem, not reflected in the figure). The first stop 32 and the first distance sensor on the dial 3, the second stop 33 and the second distance sensor are matched with the first abutting surface 42 and the second abutting surface 43 on the sheave 4, so that the lifting rod can be decelerated when the lifting rod is about to rotate to a straight or vertical state, the stopping is more accurate and stable, and the design does not need to consider the length of the lifting rod and the rising and falling speed. The fixed end of the grooved pulley 4 is provided with a through hole which is fixedly connected with the rotating shaft component 5. The groove bottom of the slide groove 41 is close to the through hole. The concave cambered surface structure is matched with the convex ring. The rotating shaft assembly 5 includes a rotating shaft 51 and an arm connecting seat 52, the rotating shaft 51 is fixedly connected with the through hole of the sheave 4, and the other end extends into the first shaft hole. The rotating shaft assembly 5 is made more stable, and thus the stability in the elevating and lowering process of the elevating rod is increased. A gap is reserved between the convex ring and the grooved pulley 4. Thereby avoiding friction between the dial and the sheave 4.

In the state of fig. 1, when the round pin 31 does not enter the sliding groove 41 of the sheave 4, the second abutment surface 43 of the sheave 4 and the second stopper 33 of the dial are locked, and at this time, the lifter is stopped stably and straightly.

Referring to fig. 2, in this embodiment, when the motor 1 rotates counterclockwise, the driving plate 3 is driven to rotate counterclockwise, in the process, the round pin 31 enters the sliding slot 41 of the sheave 4, and the sheave 4 is driven to rotate clockwise. Meanwhile, the sheave 4 drives the rotating shaft assembly 5 to rotate clockwise, so that the lifting rod arranged on the rotating shaft assembly 5 is lifted.

Referring to fig. 3, in the embodiment of the geneva drive lifter mechanism, when the round pin 31 is about to leave the chute 41 again, the first distance sensor of the first stopper 32 of the dial 3 senses the first abutting surface 42 of the sheave 4, so that the motor is decelerated, and the first stopper 32 of the dial 3 is jammed with the first abutting surface 42 of the sheave 4, thereby stopping the lifting process of the lifter. Due to the first stop 32 and the first sensor, a stable stop of the lifting bar mechanism at the end point of the lifting of the balustrade is achieved.
