Optionally, the rotating shackle assembly 13 includes a rotating shackle body 131 and a third elastic member 132.

The rotating locking hook body 131 is rotatably disposed on the bottom wall of the bottom case 2, specifically, in the embodiment, the rotating locking hook body 131 is rotatably disposed at the second positioning column 82b on the case bottom 22, for when the latch 3 is inserted into the smart door lock and abuts against the rotating locking hook body 131, the rotating locking hook body 131 rotates, and one end of the rotating locking hook body is connected to the hook 1211, and the other end of the rotating locking hook body contacts the second push rod 112. The third elastic element 132 may be elastically disposed on the rotating hook body 131, specifically, in the embodiment, the third elastic element 132 may be disposed at the second positioning column; the third elastic member 132 may be used to provide a force for rotating the hook body 131 back to the original state.

Further, a plurality of position-limiting posts 26 may be disposed on the housing bottom 22, and the third elastic member 132 may be hooked on the corresponding position-limiting posts 26, so that the third elastic member 132 may provide a torque to rotate the rotating latch hook body 131 along a set angle.

Alternatively, the torsion springs may be used for both the second elastic member 122 and the third elastic member 132.

Specifically, in this embodiment, the smart door lock 200 only needs to ensure the salt spray test and can prevent rusting, except for the electronic devices (the electromagnet body 103 and the microswitch body 114) and the other mechanical devices (the swing hook assembly 1212 and the rotary latch hook assembly 1313).

Specifically, in this embodiment, the self-locking process of the intelligent door lock 200 with the waterproof structure 100 is substantially as follows:

as shown in fig. 13 and 14, the latch 3 can be inserted in alignment with the latch slot 7, during the insertion process, the latch 3 will push the rotating latch hook body 131 to rotate against the torsion of the third elastic member 132, and after rotating to a certain angle, the rotating latch hook body 131 will contact with the swing hook body 121, thereby pushing the swing hook body 121 to rotate; when the hook body 121 rotates to a certain angle, one end of the rotating hook body 131 slides into the hook 1211 of the hook body 121, and the hook body 121 rebounds and rotates under the torque of the second elastic member 122, and the third elastic member 132 generates a rebounding torque to tightly press the rotating hook body 131 against the hook body 121. At this time, the latch catch 3 is caught by the rotating latch hook body 131, and the latch catch 3 cannot be pulled out by an external force, thereby forming a self-lock.

As shown in fig. 14, in the self-locking process, the rotating latch hook body 131 can move into the waterproof slot 24 through its cam, the second push rod 112 can compress the first elastic member 113 and contact the contact of the micro switch body 114 in the moving process, the switch is triggered, the circuit is conducted, and the micro switch body 114 is electrically connected to the control main board of the external device, so that the conducting signal can be transmitted to the control main board, thereby the external device senses that the latch 3 has completed the self-locking action. The electromagnet body 103 is also electrically connected to the control main board, but in the process of completing the self-locking, the control main board does not provide power to the electromagnet body 103, the electromagnet body 103 can be always in the power-off state, so that no magnetic force is generated, and the first push rod 102 can move freely.

The unlocking process of the smart door lock 200 having the waterproof structure 100 is substantially:

as shown in fig. 15 and 16, after the external device receives the unlocking command, the control main board provides power to the electromagnet body 103, after the electromagnet body 103 is powered on, magnetic force is generated, the magnetic force pulls the first push rod 102 into the waterproof slot 24, so as to drive the swing hook body 121 to rotate, after the swing hook body 121 rotates to a certain angle, the rotating lock hook body 131 rotates under the action of the torque force of the third elastic member 132, and after the rotating lock hook body 131 rotates to a certain angle, the rotating lock hook body 131 ejects the lock catch 3, so as to complete the unlocking action.

As shown in fig. 16, in the unlocking process, the second push rod 112 extends out of the waterproof slot 24 to the movement limit position of the second push rod 112 under the pushing force of the first elastic member 113, at this time, the micro switch body 114 is electrically disconnected from the control main board, that is, a disconnection signal is transmitted to the control main board, and after receiving the disconnection signal, the external device stops supplying power to the electromagnet body 103; after the electromagnet body 103 is powered off, the magnetic force disappears, and the swing hook body 121 drives the swing hook body 121 to rotate and reset under the action of the torque force of the second elastic member 122.

Certainly, the self-locking and unlocking modes of the intelligent door lock 200 are not unique, and the operation mode is determined according to the electronic devices and the mechanical devices which are substantially arranged in the waterproof structure 100, that is, the implementation mode of the structure of the intelligent door lock 200 is not unique, and the electronic devices and the mechanical devices can be arranged according to actual requirements.

Compared with the prior art, the waterproof structure 100 and the intelligent door lock 200 of the intelligent door lock provided by the embodiment of the invention have the following main beneficial effects:

the waterproof structure 100 of the intelligent door lock comprises a face shell 1 and a bottom shell 2, wherein the face shell 1 is covered on the bottom shell 2, an accommodating cavity is formed between the face shell 1 and the bottom shell 2, a convex rib 27 is convexly arranged on the bottom wall of the bottom shell 2 in the accommodating cavity, and a waterproof groove 24 for placing an electronic device is defined between the convex rib 27 and the bottom shell 2;

the waterproof structure 100 further comprises a first sealing element 4 and a second sealing element 5, wherein the first sealing element 4 is positioned between the bottom of the face shell 1 and the top of the waterproof groove 24 and is in interference fit with the bottom of the face shell 1 and the top of the waterproof groove 24; the side wall of the waterproof groove 24 is provided with a communicating hole group 23 for passing through an electronic device, and the second sealing element 5 is arranged at a through hole corresponding to the communicating hole group 23 in an interference fit manner.

Adopt this waterproof construction 100's intelligent lock can improve waterproof performance to a great extent promptly, can reach the water-proof effects of IPx6 grade, drenched or the post great extent of soaking by the rain has reduced the possibility of the electronic device short circuit in the intelligent lock, has stopped to damage equipment or has aroused the risk of conflagration, has guaranteed the normal use and the life of intelligent lock. And this intelligence lock design is simple reliable, and size and weight are lighter and more handy.
