Referring to fig. 1 and fig. 2, fig. 1 is a cross-sectional view of a front shell assembly when a key is pressed once according to an embodiment of the present invention, and fig. 2 is a partial enlarged view of a self-locking switch and a key in fig. 1, the present invention provides a front shell assembly, which includes a face cover 20 and a front shell 50, wherein a self-locking switch 30 is disposed on the face cover 20, the self-locking switch 30 has a lock cylinder 31, and a fastening position 33 is disposed on the self-locking switch 30; the front shell 50 is provided with a key 40, and an elastic part 70 for resetting the key 40 is arranged between the front shell 50 and the key 40; the key 40 is provided with a fixing buckle 41; when the key 40 is pressed once, the key 40 drives the elastic member 70 to elastically deform, and the key 40 drives the fixing buckle 41 to be buckled on the buckle position 33, so that the key 40 drives the front shell 50 to be attached to the face cover 20; when the key 40 is pressed for the second time, the lock core 31 ejects the fixing buckle 41 from the buckle position 33, so that the key 40 drives the front shell 50 to be separated from the face cover 20.

Referring to fig. 4, 5 and 6, fig. 4 is a schematic diagram of a key structure according to an embodiment of the present invention, fig. 5 is a front view of fig. 4, fig. 6 is a top view of fig. 4, the key 40 and the elastic member 70 are disposed in the front housing 50, the fixing buckle 41 points to the face cover 20, and when the front housing 50 and the face cover 20 are aligned with each other, the fixing buckle 41 corresponds to the self-locking switch 30. When the button 40 is pressed toward the direction of the self-locking switch 30, the fixing button 41 and the front case 50 move synchronously and in the same direction along with the button 40.

Referring to fig. 3, fig. 3 is a schematic structural view of a self-locking switch in an embodiment of the present invention, where the self-locking switch 30 is a push-button switch with a mechanical lock, when a lock cylinder 31 of the self-locking switch 30 is pressed once, the lock cylinder 31 cannot be completely ejected after releasing a hand, the lock cylinder 31 is in a locked state on the self-locking switch 30, and when the lock cylinder 31 is pressed twice, the lock cylinder 31 is ejected to the outside of the self-locking switch 30. The key 40 and the elastic member 70 cooperate to form an elastic button structure provided on the front case 50.

When the key 40 is pressed once, the front shell 50 and the fixing buckle 41 move synchronously towards the face cover 20 along with the key 40 until the fixing buckle 41 is buckled on the buckling position 33, so that the fixing buckle 41 is pressed on the lock cylinder 31 once, the lock cylinder 31 is pressed towards the inner side of the self-locking switch 30, the front shell 50 is attached to the face cover 20, at this time, the elastic piece 70 generates elastic deformation, and under the action of the elastic piece 70, the front shell 50 is pressed on the face cover 20

When the key 40 is pressed for the second time, the lock cylinder 31 pops out of the self-locking switch 30, and generates elastic force action on the fixing buckle 41, so that the fixing buckle 40 moves in the direction away from the self-locking switch 30; meanwhile, when the key 40 is pressed once, the elastic member 70 is elastically deformed, and when the key 40 is pressed twice, the elastic member 70 is continuously deformed, so that the elastic force exerted on the key 40 is further increased, when the fixing buckle 41 is popped out from the buckle position 33, under the elastic force action of the elastic member 70, the key 40 is subjected to a force moving in a direction away from the self-locking switch 30, and at this time, the key 40 is simultaneously subjected to the elastic force action of the lock cylinder 31 and the elastic member 70, so that the key 40 drives the front shell 50 to be popped out quickly in a direction away from the face cover 20.

When the key 40 is pressed once, the fixing buckle 41 is buckled on the buckling position 33, so that the front shell 50 is elastically pressed on the face cover 20, and the front shell 50 is fixed; when the key 40 is pressed for the second time, the front shell 50 can be automatically ejected along with the key 40, so that the front shell 50 can be automatically detached. When the lock is disassembled, the fixing buckle 41 is directly ejected by the lock cylinder 31, and the face cover 20 or the self-locking switch 30 cannot be damaged. Realize that a key uncaps to pop out, the dismouting that a key closed the door is experienced, and the user can not, be difficult for and inconvenient scheduling problem of opening the door when trading the core. In the scheme, the relative position relationship between the key 40 and the self-locking switch 30 is unique, so that the problem of relative dislocation does not exist after installation, and the front shell 50 can be effectively ensured to keep a constant position.

With reference to fig. 2, in the present disclosure, a mounting hole 21 may be formed in the face cover 20, the self-locking switch 30 is mounted inside the mounting hole 21, and the fastening position 33 is located inside the mounting hole 21, so that when the fixing fastener 41 is fastened on the fastening position 33, the front shell 50 can be completely pressed on the face cover 20 under the action of the elastic element 70.
