DETAILED DESCRIPTION

[0028] In order to make the person skilled in the art better understand the technical scheme in the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor shall fall within the scope of protection of the present application.

[0029] In an embodiment, referring to Figures 1 to 7 The present application provides an emergency unlocking structure of an intelligent door lock, which comprises a lock body 1, the lock body 1 comprising a lock cylinder 11 and a lock scale 12, the lock cylinder 11 being provided with a lock hole 111, the first end of the lock scale 12 being located inside the lock hole 111 and the second end being located outside the lock hole 111 and being controllably rotatable around the first end within the opening range of the lock hole 111. And under the action of an external torque, the lock scale 12 can also rotate around the central axis of the lock hole 111, transmitting the external torque acting on itself to the knob 112 of the lock cylinder 11, driving the knob 112 of the lock cylinder 11 to rotate to open the lock body 1.

[0030] Specifically, the emergency unlocking structure of the intelligent door lock comprises a panel 2 and a rotating piece 3, the panel 2 being used for being mounted to the intelligent door, and in actual application, the above-mentioned panel 2 is mostly mounted to the side of the intelligent door located indoors, and the rotating piece 3 is rotatably connected to the panel 2, the rotating piece 3 being provided with a first accommodating groove 311 recessed along the rotation axis and adapted to face the lock hole 111, and the first accommodating groove 311 being provided with a first guide surface 3111, and in the recessed direction of the first accommodating groove 311, the distance between the first guide surface 3111 and the rotation axis of the rotating piece 3 gradually decreases.

[0031] In actual application, the lock body 1 is first mounted to the intelligent door, and then the panel 2 which has been assembled with the rotating piece 3 is mounted to the intelligent door. In the process of mounting the panel 2, the first accommodating groove 311 on the rotating piece 3 is aligned with the lock hole 111, and then the panel 2 is moved so that the rotating piece 3 gradually approaches the lock scale 12 extending out of the lock hole 111.

[0032] When the rotating piece 3 does not contact the lock scale 12, since the length of the lock scale 12 located outside the lock hole 111 is generally greater than the length of the lock scale 12 located inside the lock hole 111, and the mass of the lock scale 12 located outside the lock hole 111 is also greater, under the action of its own gravity, the height of the second end of the lock scale 12 will be lower than the height of the first end.

[0033] In the process that the rotating member 3 gradually moves towards the locking ruler 12, the second end of the locking ruler 12 first enters the first accommodating groove 311 and then contacts the first guide surface 3111. Since the second end of the locking ruler 12 can rotate around the first end, the second end of the locking ruler 12 gradually moves along the first guide surface 3111 and continuously adjusts the angle of the locking ruler 12 entering the first accommodating groove 311 until the panel 2 and the rotating member 3 are installed.

[0034] As can be seen from the above operation process, the first guide surface 3111 can continuously adjust the angle of the locking ruler 12 in the process that the rotating member 3 combines with the locking ruler 12, so as to avoid the situation that the first accommodating groove 311 cannot be aligned with the locking ruler 12, thereby improving the installation efficiency of the panel 2 and the rotating member 3.

[0035] In an embodiment, referring to FIG. 1, the first accommodating groove 311 is provided with two first guide surfaces 3111 oppositely arranged along the first direction and located on both sides of the rotation axis of the rotating member 3.
