[0020] like Figure 1 As shown, this utility model proposes a passive locking door machine system driven by a linear motor, including a door body 1, a drive mechanism, and a passive locking mechanism. The door body 1 is provided with a sliding connecting plate 2. The drive mechanism includes a motor connecting seat 3, a magnetic rail 4, and an electromagnetic coil 5. The motor connecting seat 3 is fixedly connected to the sliding connecting plate 2 through a sliding pin 6. The motor connecting seat 3 is provided with a motor mounting seat on which the motor is mounted. The electromagnetic coil 5 is fixed inside the motor mounting seat. The magnetic rail 4 is provided on the motor mounting seat and is magnetically connected to the electromagnetic coil 5, so that the magnetic rail 4 is driven by the electromagnetic coil 5 to drive the motor mounting seat to slide left and right. Through this structure, a permanent magnet synchronous linear motor is used to directly drive the door to open and close, reducing intermediate transmission devices, resulting in high transmission efficiency, no mechanical wear, and extended service life of the device.

[0021] The passive locking mechanism includes a locking pin mounting base 7, an unlocking pin 8, a locking hook 9, a roller 10, and a proximity switch 11. The unlocking pin 8 is fixed to the motor connecting base 3. The locking pin mounting base 7 is movably mounted on the sliding connecting plate 2 and is movably connected to the unlocking pin 8. The locking pin mounting base 7 extends towards the unlocking pin 8 and has a connecting part 12. The end of the connecting part 12 has a roller 13. The roller 13 is movably placed in the groove of the unlocking pin 8. When the unlocking pin 8 moves left and right with the motor connecting base 3, the roller 13 moves left and right in the groove. The right side of the groove of the unlocking pin 8 is inclined upward as the roller 13 moves radially. This design ensures that the locking hook will lift up when the unlocking pin 8 moves to the right. The roller 10 and proximity switch 11 are located on the door body 1. The locking hook 9 is fixed to the locking pin mounting seat 7 and slidably connected to the roller 10. The part of the locking hook 9 that contacts the roller 10 has a hook part. The proximity switch 11 is located below the hook part. The door body 1 is locked by contacting the proximity switch 11 through the hook part. This structure uses a passive locking device to lock and open the door. This device is a fully mechanical structure with a simple structure. Compared with electromagnetic locks, it does not have an electromagnet device and does not require an additional unlocking power source, which greatly improves reliability and security.

[0022] Furthermore, the end of the locking hook 9 is provided with a screw 14, which is assembled and connected to the locking pin mounting seat 7, and a nut 15 is provided on the screw 14 to fix the position of the locking hook 9, so that the position of the locking hook 9 can be adjusted by the extension length of the screw 14.

[0023] When the control system receives the door opening signal, the electromagnetic coil 5 drives the magnetic rail 4 to move to the left. The magnetic rail 4 drives the unlocking pin 8 to move to the left through the motor connecting seat 3. When the unlocking pin 8 moves to the left, the roller 13 at the end of the connecting part 12 of the locking pin mounting seat 7 moves to the end face of the inclined side of the groove, thereby driving the locking pin mounting seat 7 to lift up. At the same time, as the locking hook 9 moves to the left, the hook part of the locking hook 9 rolls on the roller 10, thereby lifting the locking hook 9 up by the roller 10. At this time, the hook part of the locking hook 9 disengages from the roller 10, realizing the unlocking function. The magnetic rail 4 continues to drive the door body 1 to move, and the door opening action is completed.

[0024] When the control system receives the door closing signal, the electromagnetic coil 5 drives the magnetic rail 4 to move to the right. The magnetic rail 4 drives the door body 1 and the locking pin mounting seat 7 to move to the right together through the motor connecting seat 3 and the sliding connecting plate 2. When the locking hook 9 touches the roller 10, the hook part of the locking hook 9 will be lifted up along the slope. When the hook part of the locking hook 9 completely passes the roller 10, the locking hook 9 falls down by its own weight, realizing the locking function, and sends the door body 1 locking information through the proximity switch 11.

[0025] When the door 1 is closed, if you try to open it by pushing it open with external force, the door 1 cannot be opened because the locking hook 9 and the roller 10 are locked, thus achieving a safe lock. When the electromagnetic coil 5 drives the magnetic rail 4 to move, it lifts the locking pin mounting seat 7 and the locking hook 9 upwards through the unlocking pin 8, thus unlocking the mechanism.

[0026] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
