Electronic roll-up shutter 10 also comprises the position-limit mechanism (not shown), and when heavy curtain 12 rose to the extreme higher position or drops to extreme lower position, this position-limit mechanism can make heavy curtain 12 stop action.This position-limit mechanism is electrically connected (with reference to Figure 1B) with controller 21, and provides the electric signal of expression heavy curtain 12 when arriving extreme higher position and extreme lower position respectively for controller 21.This position-limit mechanism uses in many electronic roll-up shutters commonly used, so be not described in detail in this.Illustrated among Fig. 2 B, Fig. 3 and Fig. 4 when heavy curtain 12 is in extreme lower position, wherein, there is little gap in the relative position between ground FL and heavy curtain 12 root edges between the lower surface of the tube 28 of ground FL and edge member 24.
Generally, the relative position between ground FL and heavy curtain 12 root edges is such, and promptly when heavy curtain 12 dropped to extreme lower position fully, the lower surface of the tube 28 of ground FL and edge member 24 almost was on the same horizontal plane.Yet it is not necessary having little gap between the lower surface of the tube 28 of ground FL and edge member 24.In other words, when heavy curtain 12 dropped to extreme lower position, ground FL can contact with the lower surface of tube 28, also can have relatively large gap.Importantly, must guarantee that the least significant end of aliform portion 32 touches ground FL, so that can cover and protect tube 28.
But, Fig. 2 B, Fig. 3 and ground FL shown in Figure 4 and the relative position between heavy curtain 12 root edges are best, because this makes tube 28 can not contact with ground FL, thereby be that convenient heavy curtain 12 drops to extreme lower position after a very long time, any distortion can not take place in the diapire of the semicircle tubular of tube 28 yet.
End at heavy curtain shown in Figure 3 12 root edges is provided with the beam launcher that is made of laser beam transmitter 34.Laser beam transmitter 34 end of parts 24 that keeps to the side, and be fixedly mounted in by means of support 36 on the least significant end batten 22 of heavy curtain 12.Laser beam transmitter 34 is the midget plants that are made of laser diode, and its position is towards making that the light beam of launching (being laser beam herein) 38 can be along the cavity 30 that vertically passes edge member 24 inside of edge member 24.
The other end at the root edge of heavy curtain shown in Figure 4 12 is provided with optical sensor 40, this optical sensor 40 other end of parts 24 that keeps to the side, and be fixedly mounted in by means of support 42 on the least significant end batten 22 of heavy curtain 12.The position of this optical sensor 40 is towards making it can receive laser beam from the cavity that passes edge member 24 30 of laser beam transmitter 34.
In the process that the heavy curtain 12 of electronic roll-up shutter 10 descends, between ground FL and the heavy curtain 12 that descending obstruction appears possibly, especially the people.When this happens, obstruction can impose on external force of diapire of the tube 28 of edge member 24, and the part that causes edge member 24 to contact with obstruction deforms and is crushed.As long as some is crushed tube 28, the laser beam launched from laser beam transmitter 34 will be stopped by the part that tube 28 has flattened so, thereby just can't shine on the optical sensor 40.
