Through the above structure, the configuration and application of the access control device of the barrier-free toilet can be completed. .

The actual use state of the access control device can be seen from Figures 4, 5, and 6. The hanging rail 10 is connected to the door body 50 and is installed at the door of a barrier-free toilet. One of the driving units 20 is The electromagnet group 22 is located above the door. The electromagnet group 22 and the magnetic attraction member 42 of the sliding member 40 have opposite magnetic poles to produce an attraction effect, while the other electromagnet group 22 of the driving unit 20 is away from the door. The magnetic poles of the magnetic attraction member 42 of the sliding member 40 produce a repulsive effect, whereby the door body 50 is normally closed. At the same time, the electric bolt lock 30 promotes the magnetic movement of the bolt 34 through the magnetic repulsion of the electromagnet 32 The component 342 allows the latch 34 to sink through the channel 13 and be inserted into the locking hole 412 of the sliding seat 41 so that the door 50 is in a locked state. The external sensor 61 is installed in the barrier-free toilet. In addition, the inner sensor 62 is installed in the barrier-free toilet, and the outer and inner sensors 61 and 62 are electrically connected to the electric control board 21 of the driving unit 20, and then receive the outer sensor 62 through the electric control board 21. , the internal sensor 61, 62 signals further control each electromagnetic coil 221 of the two electromagnet groups 22 to produce magnetic pole changes and the electromagnet 32 of the electric mortise lock 30 to produce magnetic field changes; Therefore, when the user wants to open the door 50 to enter the barrier-free toilet, as shown in Figures 7, 8, and 9, he or she should bring his or her hand close to the external sensor 61 and use a gesture to sense the external sensor. The sensor 61 generates a door-opening induction signal and transmits it to the electric control board 21. After receiving the signal, the electric control board 21 controls the electromagnet 32 to generate a magnetic field change and the electromagnetic coil 221 to generate a magnetic pole change. At this time, the electric control panel 21 The electromagnet 32 of the latch lock 30 will first attract and pull the magnetic component 342 due to the change of the magnetic field, causing the latch 34 to rise and separate from the locking hole 412 of the sliding seat 41 to form the unlocked state of the door 50. The electromagnet group located above the doorway 22 has the same magnetic pole state as the magnetic attraction member 42 of the sliding member 40 after the magnetic pole change of the electromagnetic coil 221, so that the electromagnet group 22 and the magnetic attraction member 42 produce a repulsive effect, and the electromagnet group 22 away from the door is After the magnetic pole of the electromagnetic coil 221 changes, it has a different magnetic pole state from the magnetic attraction member 42 of the sliding member 40, thereby producing an attraction effect. Through this, the magnetic attraction member 42 of the sliding member 40 is repelled and floated by the electromagnetic coil 221 with the same magnetic pole. , and then are attracted and slid by the electromagnetic coils 221 with different magnetic poles, so as to drive the sliding member 40 to move along the sliding groove 12, and further link the door body 50 to open the door, so that the user can enter the barrier-free toilet. within.

When the user enters the barrier-free toilet, as shown in Figures 10, 11, and 12, the user needs to bring his hand close to the inner sensor 62 and sense it with a gesture, so that the inner sensor 62 generates a door closing The induction signal is transmitted to the electric control board 21, and the two electromagnet groups 22 are controlled by the electric control panel 21 to produce magnetic pole changes again. At this time, the electromagnet group 22 far away from the door contacts the sliding member after the magnetic pole changes of the electromagnetic coil 221. The magnetic poles 42 of the sliding member 40 have the same magnetic pole state, thereby producing a repulsive effect, and the electromagnet group 22 located above the door has different magnetic poles from the magnetic poles 42 of the sliding member 40 after the magnetic poles of the electromagnetic coil 221 are changed. state, causing the electromagnet group 22 and the magnetic attraction member 42 to generate an attraction effect, so as to drive the sliding member 40 to move along the sliding groove 12 toward the door, and further link the door body 50 to close the door. When the door When the door body 50 is in a closed state, the electronic control board 21 also determines that the door body 50 has been closed through the magnetic pole change state of the electromagnet group 22, so as to control it again. The electromagnet 32 of the electric bolt lock 30 generates a magnetic field change and repels the magnetic component 342 that pushes the bolt 34, causing the bolt 34 to sink through the channel 13 and be inserted into the locking hole 412 of the sliding seat 41. The door 50 is put into a locked state.

In addition, when the user enters the barrier-free toilet and closes the door through the inner sensor 62, the outer sensor 61 will light up the display light 611, as shown in Figure 13, to inform that there is someone in the barrier-free toilet. The light signal effect is in use, and the outer sensor 61 will form a non-sensing state at the same time to prevent the outer sensor 61 from being sensed and opening the door 50 to ensure the safety of using the toilet; after using the toilet, pass through the inner When the sensor 62 senses the door opening, the display light 611 of the outer sensor 61 will go out and return to the state of being able to sense the opening and closing of the door, so that the door 50 can be closed through the outer sensor 61 after use. The door of the barrier-free toilet; if the door 50 is not closed again through the external sensor 61 after using the toilet, after a period of time when no one is in use, the electric control panel 21 of the drive unit 20 will automatically control the door 50 The electromagnet group 22 generates magnetic pole changes, so that the door 50 can automatically return to the normally closed state, and simultaneously controls the electromagnet 32 to generate magnetic field changes, and sinks the pin 34 of the electric plug lock 30 into the sliding seat 41 Locking hole 412.

Furthermore, when the above-mentioned access control device is used for the first time, the sliding member 40 will first run back and forth in the sliding groove 12 once, and will be blocked by the stop seats 14 at both ends of the sliding groove 12 and at the same time through the linear Hall induction of the driving unit 20 The sensor 23 senses the sliding path of the sliding member 40, and thereby obtains a better frequency of magnetic pole change, so as to facilitate the adjustment of the displacement speed of the sliding member 40. Therefore, when used again, the two electromagnet groups 22 can follow the The sliding path of the lower groove 12 provides a better opportunity for magnetic pole change, so that when the sliding member 40 moves to both ends, the number of electromagnetic coils 221 with different magnetic poles can be increased through the change of magnetic poles of the electromagnetic coils 221, and at the same time, the number of electromagnetic coils 221 with the same magnetic poles can be reduced. The number of electromagnetic coils 221 has the effect of buffering the speed change and prevents the sliding member 40 from directly hitting the two stop seats 14, which helps to reduce noise generators.

In addition, when the electric bolt lock 30 is in the locked state, the elastic member 341 is pressed down by the magnetic component 342 of the bolt 34 to form a compressed state. When the power supply of the access control device is abnormal, the electric bolt lock 30 can also pass through The elastic member 341 pushes the latch 34 upward, causing the latch 34 to disengage from the locking hole 412 of the sliding seat 41, thereby allowing the door 50 to be in an unlocked state and can be pushed open.

In another use embodiment of its structure, the door 50 can be set to a normally open state through outer and inner sensors 61 and 62, and the outer sensor 61 does not have the effect of general gesture sensor opening. When the user enters the door without When using a handicap toilet, you can also close the door by moving your hand close to the inner sensor 62 and perform gesture sensing, so that the inner sensor 62 generates a door closing sensor signal and transmits it to the electric control panel 21, which further links the door body 50 to close the doorway. , and sink the latch 34 through the channel 13 and insert it into the locking hole 412 of the sliding seat 41, so that the door 50 is in a locked state, and at the same time, the outer sensor 61 will light up the display light 611. , as a light signal to inform that someone is using the barrier-free toilet. When the door is opened through the inner sensor 62 after using the toilet, the display light 611 of the outer sensor 61 will go out and the door 50 will be restored. The normally open state. In addition, when the door 50 is in a normally open state, the external sensor 61 can be set with a special gesture or other sensing method for emergency opening. If there is an emergency, if the door 50 is not opened for a long time and the user is suspected of fainting Or when an internal situation such as calling for help occurs, the external sensor 61 can open the door 50 through a special gesture or other sensing method, allowing immediate rescue inside to avoid regrettable situations.
