Detailed Description

in order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

the present embodiment discloses a lock assembly. The lock assembly of the present embodiment can detect the insertion or extension of the latch bolt 310 into or out of the housing.

to achieve the above, please refer to fig. 1. The lock assembly of this embodiment includes an inner housing 200. The inner case 200 includes an upper case 210 and a lower case 220 which are integrated. The lower housing 220 is configured with a hollow lower receptacle 222, the lower receptacle 222 being for mounting the electromagnetic lock 300; upper housing 210 is integrally formed above lower housing 220 and is formed with an upper receptacle 212. The upper receiving cavity 212 is used for the bolt 310 of the electromagnetic lock 300 to penetrate above the inner case 200.

specifically, the upper end of the lower housing 220 is configured with a lower through-hole 221, and the lower through-hole 221 allows the latch bolt 310 of the electromagnetic lock 300 to pass through and protrude into the upper receiving cavity 212. The upper end of the upper housing 210 is configured with an upper bore 211, the upper bore 211 being axially aligned with the lower bore 221 such that the latch extending into the upper cavity 212 continues to pass through and extend above the upper housing 210.

after the electromagnetic lock 300 is matched with an external relay and a power supply, the bolt 310 can sequentially pass through the lower through hole 221 and the upper through hole 211 and then extend out of the upper part of the inner shell 200; after the locking tongue 310 extends out of the upper part of the inner shell 200, the part of the locking tongue 310 above the inner shell 200 can fully or partially extend into the upper cavity 212 through the upper through hole 211, so that the locking assembly can be opened and closed.

referring to fig. 2 and 3, in the latch 310 of the present embodiment, a connection ring 500 is fixed to a portion of the upper cavity 212 along an opening/closing direction of the extending or retracting; at the same time, a contact extending into micro switch 600 is installed in upper cavity 212, and the contact is configured to be effectively pushed away by connection ring 500 when latch 310 extends into upper cavity 212.

Preferably, the contacts of micro-switch 600 are activated by a contact configured to be effectively pushed open by connecting ring 500 when latch 310 is inserted into upper housing 212.

Referring to fig. 4, a plurality of contacts of the micro switch 600 are preferably installed in the upper cavity 212, and can surround the axis of the latch 310 for being effectively pushed away by the connection ring 500 at the same time.

referring to fig. 5, in the preferred upper cavity 212 of this embodiment, a plurality of contacts of the micro switch 600 are installed and extend into the upper cavity, and the plurality of contacts can be arranged along the axis of the latch 310, so that the latch 310 can be sequentially and effectively pushed away by the connection ring 500 when extending into the upper cavity 212.

Referring to fig. 3, the spring 400 is sleeved on the portion of the upper cavity 212 of the locking tongue 310 of the present embodiment, one end of the spring 400 abuts against the lower surface of the connecting ring 500, and the other end abuts against the bottom of the upper cavity 212; and the diameter of the connection ring 500 is larger than that of the upper penetration hole 211.

Further, the spring 400 is configured to be in a non-deformed state when the latch tongue 310 is extended above the inner case 200 and in a deformed state when the latch tongue 310 is extended into the upper receiving cavity 212.

The latch 310 of the present embodiment can be partially kept extended above the inner case 200 by the spring 400, so as to achieve the closed state of the lock assembly; only after the electromagnetic lock 300 responds to an external signal generated by an external relay and a motor and generates an electromagnetic force, the latch bolt 310 overcomes the deformation of the spring 400 and extends into the upper cavity 212, and the open state of the lock assembly is achieved.

Referring to fig. 6, the inner case 200 of the present embodiment is mounted with the outer case 100 by bolts. The housing 100 is used to mount the PCB 700, and the pins of the micro switch 600 are soldered to the PCB and face the outside of the housing 100. The PCB 700 can be mounted with a detection circuit for generating a trigger signal to the outside according to the contact trigger of the micro switch 600.

Meanwhile, the housing 100 is configured with two connecting side plates, the connecting side plates are configured with mounting holes, and the connecting side plates realize the lock assembly of the embodiment on a door panel and other structures through the mounting holes and screws.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
