[0001] The present invention belongs to the technical field of pet management, and relates to a pet door, and in particular to a pet door with a locking mechanism and a pet door control method. Background Art

[0002] Nowadays, many people keep pets, some because they are a hobby, and some because they need companionship. Pets not only need food, shelter and shelter, but also often need entertainment activities and walks outside. This is especially true for some more active pets. It would be very troublesome if you need to close and open the door for the pet all the time, so some pet doors have appeared on the market.

The door body 200 is located between the door interior 110 and the door exterior 120. The door body 200 can rotate toward the door interior 110 or the door exterior 120. The locking hole 130 is arranged between the door interior 110 and the door body 200, and between the door exterior 120 and the door body 200.

[0051] Among them, the first locking mechanism 300 is arranged on the door frame 100 and is located between the door interior 110 and the door body 200. The first locking mechanism 300 includes a locking seat 310 and a locking pin 320. The locking seat 310 is located in the door frame 100 and can be raised and lowered relative to the door frame 100. The locking pin 320 is connected to the locking seat 310, and the locking pin 320 can extend or retract into the locking hole 130.

[0052] Specifically, when the locking pin 320 of the first locking mechanism 300 extends out of the locking hole 130, the locking pin 320 of the first locking mechanism 300 can contact the limiting side 220 to limit the door body 200 from rotating toward the door interior 110; when the locking pin 320 of the first locking mechanism 300 retracts into the locking hole 130, the door body 200 can rotate freely toward the door interior 110.

[0053] The second locking mechanism 500 is disposed on the door frame 100 and is located between the door exterior 120 and the door body 200 . The structure of the second locking mechanism 500 is the same as that of the first locking mechanism 300 .

[0058] In this embodiment, the return spring 330 pushes the locking seat 310 and drives the locking pin 320 to extend out of the locking hole 130. Therefore, under normal circumstances, the locking pin 320 can contact the limiting side 220 to limit the door body 200 from rotating toward the inside 110 of the door or the outside 120 of the door, thereby playing a role in safety protection and limiting the entry of foreign pets or the escape of pets in the house.

[0059] like Figure 1-Figure 6As shown, on the basis of the above embodiment, the locking seat 310 is provided with a pressure plate 311, and the first locking mechanism 300 also includes a rotating shaft 340 and an eccentric wheel 350, the rotating shaft 340 is fixed relative to the door frame 100 and can rotate around its own axis, the eccentric wheel 350 is connected to the rotating shaft 340, and the pressure plate 311 is located between the eccentric wheel 350 and the reset spring 330.

[0060] Specifically, the rotation of the rotating shaft 340 around its own axis can be controlled manually or automatically, which is not specifically limited here.

9. A pet door control method, characterized in that: A pet door with a locking mechanism as claimed in claim 7, further comprising a method: The remote control system performs timing, which is divided into access control time and free time. During the access control time, the remote control system automatically controls the motor of the second locking mechanism so that the locking pin extends out of the locking hole, thereby limiting the door body from rotating toward the outside of the door; during the free time, the remote control system automatically controls the motor of the second locking mechanism so that the locking pin retracts into the locking hole, thereby allowing the door body to rotate freely toward the outside of the door; The remote control system performs temporary control to control the motor of the second locking mechanism so that the locking pin extends out of or retracts into the locking hole.

10. A pet door control method as claimed in claim 9, characterized in that: Also includes a pet facial recognition system, the pet facial recognition system is connected to the door frame and is located outside the door, the pet facial recognition system is electrically connected to the motor and is used to recognize the pet's face so as to control whether the motor works, the pet facial recognition system is communicatively connected to the remote control system, the remote control system is communicatively connected to the motor of the first locking mechanism and is used to control whether the motor of the first locking mechanism works; Also includes methods: A known pet face is recorded in the remote control system. When the pet face recognition system recognizes an unfamiliar pet face, the pet face recognition system automatically controls the motor of the first locking mechanism so that the locking pin extends out of the locking hole, thereby limiting the door body from rotating toward the inside of the door; When the pet facial recognition system recognizes a known pet face, the pet facial recognition system automatically controls the motor of the first locking mechanism so that the locking pin is retracted into the locking hole, so that the door body can be freely rotated toward the inside of the door; The remote control system performs temporary control to control the motor of the second locking mechanism so that the locking pin extends out of or retracts into the locking hole.
