In the box 131, when the simulated lock tongue 132 and the lock hook mechanism 133 are matched, since the thimble piece 135 cannot abut the door frame at this time, the trigger control device 136 cannot send the electronic lock 13 to the control module of the switch cabinet 10 to close the lock. In this way, the electronic lock 13 cannot be converted to the locked state, thereby eliminating the hidden danger of the electronic lock 13 being misjudged as the locked state. In this way, the control module of the switch cabinet 10 cannot confirm the lock information of the electronic lock 13 It can send out alarm information to the outside world through sound and light alarm, so as to ensure the safety of the battery and other electrical components inside.

In some other embodiments of the present application, as shown in FIGS. 2 to 4, the trigger control device 136 includes a first micro switch 137 and a control chip 138, the trigger piece 140 of the first micro switch 137 and one end of the thimble member 135 When the thimble member 135 abuts against the door frame and moves into the lock box 131, the first micro switch 137 is triggered, so that the first micro switch 137 sends a lock signal to the control chip 138 to control the chip 138 is used to send the lock information of the electronic lock 13 to the control module after acquiring the lock signal.

Specifically, when the cabinet door 12 is closed, the thimble member 135 contacts the door frame and moves into the lock box 131 under the push of the door frame, and touches the trigger piece 140 of the first micro switch 137. At this time, the first micro switch 137 is pressed. A micro switch 137 is turned on, and then sends a lock signal to the control chip 138. The control chip 138 is used to send the lock information of the electronic lock 13 to the control module after obtaining the lock signal, thus realizing the control module pairing The lock state of the electronic lock 13 is learned.

In some other embodiments of the present application, as shown in FIGS. 2 to 4, the trigger control device 136 further includes a second micro switch 139. When the hook mechanism 133 and the bolt 132 are unhooked, the second micro switch 139 is triggered so that the second micro switch 139 sends an unlock signal to the control chip 138, and the control chip 138 is used to obtain the unlock signal, Send the electronic lock 13 unlocking information to the control module.

Specifically, when the cabinet door 12 is opened, the driving mechanism 134 drives the hook mechanism 133 and the bolt 132 to release the hook. At this time, the hook mechanism touches the trigger piece 140 of the second micro switch 139, thereby causing the second micro switch 139 The switch 139 is turned on, and then the second micro switch 139 sends an unlocking signal to the control chip 138. The control chip 138 is used to send the electronic lock 13 unlocking information to the control module after obtaining the unlocking signal, thus realizing the control module pairing The unlocking state of the electronic lock 13 is known.
