Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, 2, 3a and 3b, an automatic telescopic zero-gap car door sill comprises an electric push rod 1 and a movable support 2, wherein the push rod part of the electric push rod 1 is welded and fixed through a mounting plate arranged on the movable support 2, the electric push rod 1 is connected with an elevator control system, and the electric push rod 1 receives a control system signal and retracts and expands; the electric push rod 1 is arranged below the car platform 5 through a fixing bolt 4; a fixed sill 3 is fixedly connected above the front side of the car bottom 5 through a hexagon bolt 6, the fixed sill 3 and the movable support 2 are mutually matched and connected, the movable support 2 and the fixed sill 3 are lapped without gaps, and various safety problems caused by gaps are reduced; a switch 8 which extends in place is arranged in the movable support 2, a landing sill 9 is arranged on one side of the switch 8 which extends in place, a roller extending out of one side of the switch 8 which extends in place is connected with the outer wall of one side of the landing sill 9, the switch 8 which extends in place acts, the power supply of the motor of the electric push rod 1 is cut off to stop running, and the movable support 2 is in a completely extending state; a retraction in-place switch 7 is fixedly arranged at the lower part of the movable support 2, the retraction in-place switch 7 acts, the power supply of the motor of the electric push rod 1 is cut off to stop running, and the movable support 2 is in a complete retraction state at the moment; the roller is connected with a stretching-out-to-place switch 8 and a retracting-to-place switch 7 through a fixing piece, after the roller collides with the outer wall on one side of the landing sill 9, the force is acted on the stretching-out-to-place switch 8 and the retracting-to-place switch 7 through the action of the force transmitted by the fixing piece, and the power supply is cut off; the upper part of the circuit operation schematic diagram is a schematic diagram of a fully retracted state, the lower part of the circuit operation schematic diagram is a schematic diagram of an extended in-place state, two ends of the circuit operation schematic diagram are respectively connected with AC110V and OV, a left-end safety loop switch is closed, a partially extended in-place switch 8 on the schematic diagram is opened, and a retracted in-place switch 7 is closed; the lower part of the diagram extends to the in-position switch 8 to be closed, and the retraction to the position switch 7 to be opened.
