Photoelectric sensor is arranged in the car door, and the electromagnet is connect with control device with photoelectric sensor.Electromagnet release tensioning
After wheel, belt slack, power transmission cut-out, while motor and car door are protected, the control of tensioning wheel is transmitted by photoelectric sensor to be believed
Number.
Preferably, the car body also sets up limit switch, and the limit switch includes first switch and second switch, described
First switch is arranged with second switch at the both ends of the car door direction of motion, and limit switch is connect with control device.Limit switch can
To control the switch of photoelectric sensor when car door opens or closes completely.
Wherein, the limit switch further includes third switch, and the third switch is arranged in first switch and second switch
Between, close to first switch.Third switch can change motor speed in triggering, and car door is made to slow down.
Wherein, the limit switch is travel switch.Travel switch can be triggered when car door moves to corresponding position, and machine
Tool structure is more reliable and more stable.
Wherein, protective cover is arranged in the beneath window, cavity is arranged in the protective cover, handle is located in cavity.Protection
Cover can prevent sundries from entering with cavity, further increase safety.Protective cover can prevent foreign matter from entering, false triggering switch.
Preferably, the tensioning wheel is connect by rocking arm with car body, and rocking arm is rotatablely connected with car body, and the track is circular arc
Shape.It is connected by rocking arm, the movement locus of tensioning wheel is more easy to control, and the convenient reset to tensioning wheel operates.
Wherein, cylinder is arranged in the car body, and cylinder is rotatablely connected with car body, and arc groove, the circular arc is arranged in cylinder head portions
Slot is located on tensioning wheel rail direction.Cylinder pushes tensioning wheel tensioning wheel can be made to reset, and arc-shaped slot is used to support tensioning wheel
Axis.
The utility model can play a protective role to rotary switch, cause to damage when preventing external force from subway door being prevented to close
Evil, while having the function of protecting passenger, prevent passenger from being crushed by subway door.
