The first tension spring 82 is stretched and connected to the first connection surface, and the second tension spring 84 is stretched and connected to the second connection surface. When the first upper link 42 and the second upper link 44 rotate, the first lower link 82 and the second lower link 84 also rotate together. The rotation of the first upper link 42 and the first lower link 82 drives the first touch panel 32 to move away from the second touch panel 34 .

The first car door 22 and the second car door 24 have two states of open and closed. In the closed state, the first car door 22 is in contact with the second car door 24; in the open state, the first car door 22 is separated from the second car door 24, and the first car door 22 is in contact with the second car door. The door 24 is a doorway for users to enter and exit. In the open state, the first contact surface protrudes from the first car door 22 , and the second contact surface protrudes from the second car door 24 .

The touch signal is transmitted to the controller, and the controller shields the safety touch panel signal to drive the first car door 22 and the second car door 24 to continue to close. If the door closing process, the contact signal is disconnected, the controller will drive the first car door 22 and the second car door 24 to open the door immediately.

In the open state, the first touch panel 32 and the second touch panel 34 have two sub-states: safe and abnormal. In the safety sub-state, the first upper link 42 touches the first limit bolt 52 , and the second upper link 4 touches the second limit bolt 54 . In this state, the first car door 22 and the second car door 24 slide between the upper sill 12 and the lower sill 14 when the controller opens and closes the doors of the elevator. In the abnormal sub-state, the first upper link 42 touches the first micro switch 62 and/or the second upper link 44 touches the second micro switch 64 .

Since the first touch plate 32 and the second touch plate 34 of the present invention are retracted into the first car door 22 and the second car door 24 by contacting and squeezing each other, instead of using rollers and curved slideways The way of lifting and retracting eliminates the guide wheel and guide groove, simplifies the structure of the upper sill, reduces the space of the upper sill, and reduces the cost. And when the first touch panel 32 is in full contact with the second touch panel 34, it will feed back a touch panel contact signal to the controller through the touch panel contact signal lines 322, 324, and the controller then shields the first micro switch 62 and the second touch panel. The second micro switch 64. By increasing the touch panel contact signal, the redundant touch panel switch, the first micro switch 62 and the second micro switch 64 are not shielded by the touch of the first upper link 42 and the second upper link 44, but in When the first touch panel 32 is in full contact with the second touch panel 34, the touch panel contact signal received by the controller is controlled to shield, so that in the state where the first car door 22 and the second car door 24 are nearly closed, the touch panel can be ensured. There is no object between the boards to ensure the safety of passengers and enhance safety to prevent potential safety hazards caused by the shielded signal of the safety touch board and ensure the safety of passengers.
