Description

Technical Field

[0001] The present invention relates to the technical field of pet doors, and in particular to an intelligent pet door and an identification system thereof. Background Art

[0002] A pet door is a door designed specifically for pets, allowing them to enter and exit the home freely without the need for humans to manually open the door. This device is usually installed outside the main door of the home or on the door of a room that the pet often visits. The design of the pet door takes into account the size and activity habits of the pet, ensuring that the pet can pass through easily while preventing larger animals or wild animals from entering the home.

[0003] Although traditional pet doors can prevent larger wild animals from entering, they are less effective against smaller wild animals. Therefore, people often install pet AI recognition systems and electric door opening components on pet doors. The installed cameras collect and compare information about animals in front of the door, and then the pet door is opened through the electric door opening component. This can accurately and effectively distinguish pets from wild animals, thereby effectively preventing smaller wild animals from entering.

[0004] Although the existing technology can effectively prevent smaller wild animals from entering by cooperating with the pet AI recognition system and the electric door opening component, in actual operation, the pet is too close to the pet door and its head rests against one side of the pet door, making it difficult for the camera to collect the pet's facial image information, resulting in poor recognition efficiency of the pet AI recognition system and inaccurate recognition results.

[0046] Combine Figure 3-6 As shown, the pet push plate 3 is arranged on the front side of the pet door panel 2 and is connected to the pet door panel 2 through an active buckle. The active buckle is arranged between the pet push plate 3 and the pet door panel 2. When the active buckle is locked, the pet push plate 3 is connected to the pet door panel 2, and when the active buckle is opened, the pet push plate 3 is separated from the pet door panel 2.

[0047] Specifically, the movable buckle includes a crank 18, two clamping blocks 19 and two elastic members 20. One end of the crank 18 is fixedly connected to the front side of the pet door panel 2, and the other end extends forward and is provided with an arc-shaped clamping joint. The two clamping blocks 19 are arranged opposite to each other up and down. The front sides of the two clamping blocks 19 are rotatably connected to the rear side of the pet push plate 3, and each of the clamping blocks 19 is connected to the pet push plate 3 through one of the elastic members 20. The clamping block 19 is provided with an arc-shaped clamping surface. The clamping surfaces of the two clamping blocks 19 are spliced ​​into an arc-shaped slot. The clamping joint can be clamped into the slot, and the central angle of the slot is greater than 180°. The clamping block 19 here is an arc-shaped block, and an upward-extending support ear 21 is provided on the outside of the arc-shaped block. The two clamping blocks 19 are approximately symmetrically arranged in the upper and lower directions.

The two elastic members 20 are arranged in parallel up and down, and the rear end of the elastic member 20 is connected to the support ear 21 and the front end is connected to the pet push plate 3.

[0048] In some embodiments, the translation assembly further includes a drive seat 13, which is stepped. The lower end of the pet push plate 3 is supported and fixed on the drive seat 13. The number of the movable clips is set to two, and the upper and lower back ends of the pet push plate 3 are respectively connected to the front side of the pet door panel 2 through two movable clips. Here, the movable clips are arranged between the pet push plate 3 and the pet door panel 2 above the rear of the drive seat 13. The front side of the pet door panel 2 is provided with a first fixing seat 22, and the rear side of the pet push plate 3 is provided with a second fixing seat 23 arranged opposite to the first fixing seat 22. The rear end of the crank 18 is fixedly connected to the first fixing seat 22, and the two clamping blocks 19 are respectively rotatably connected to the second fixing seat 23, so that the clamping joint of the crank 18 can be aligned with the clamping slots of the two clamping blocks 19 and be clamped and locked.

[0049] The translation assembly includes a drive motor 11, a first connecting rod 8, a first drive gear 7, a first half-tooth gear 6, a first drive gear 7, a second half-tooth gear 9, a first drive rod 4, and a second drive rod 5. One end of the first drive rod 4 is rotatably connected to the back of the pet door panel 2, and the other end is curved and connected to the first drive gear 7. In order to push and pull the pet door panel 2 more smoothly, a vertical translation rod 27 is provided on the rear side of the pet door panel 2. The number of the first drive rods 4 is set to be multiple, and the multiple first drive rods 4 are arranged in parallel up and down. One end of each first drive rod 4 is rotatably connected to the translation rod 27, and the other end is connected to the first drive gear 7.

[0050] One end of the second drive rod 5 is rotatably connected to the pet push plate 3, and the other end is curved and connected to the second drive gear 10. Here, the second drive rod 5 extends through the main door panel 1 and is rotatably connected to the drive seat 13. To prevent the main door panel 1 from interfering with the movement of the second drive rod 5, a long, narrow clearance groove is provided on the main door panel 1 behind the drive seat 13. A rotating seat 29 is provided on the rear side of the drive seat 13. The second drive rod 5 extends through the clearance groove and is rotatably connected to the rotating seat 29.

[0051] The first connecting rod 8 is connected to the first half-tooth gear 6 and the second half-tooth gear 9 respectively. The first half-tooth gear 6 and the second half-tooth gear 9 are staggered in the axial direction of the first connecting rod 8. The first half-tooth gear 6 is in meshing state with the first driving gear 7, and the second half-tooth gear 9 is in meshing state with the second driving gear 10.

[0052] The driving motor 11 is connected to the first connecting rod 8 to drive the first connecting rod 8 to rotate, and first the second half-tooth gear 9 is engaged with the second driving gear 10 to drive the second driving rod 5 to drive the pet push plate 3 to move outward, the active buckle is opened, and the pet push plate 3 is separated from the pet door panel 2; then the first half-tooth gear 6 is engaged with the first driving gear 7 to drive the first driving rod 4 to drive the pet door panel 2 to move outward, the active buckle is locked, and the pet push plate 3 is connected to the pet door panel 2.

[0053] The pet push plate 3 can be used to push a pet outside the main door panel 1 to a predetermined area for image capture. The pet push plate 3 is typically designed to have a small longitudinal cross-sectional area so that the pet is not obstructed during image capture. In some embodiments, the pet push plate 3 can be designed to have a larger longitudinal cross-sectional area to facilitate outward push of the pet. However, this may result in obstruction of the pet during image capture. In this case, the pet push plate 3 can be designed to be transparent to prevent obstruction of the pet during image capture.

[0054] like Figure 5 and 8 As shown, in some embodiments, a smart pet door of the present invention further includes a separation component, which includes a foot pad 25, a third driving rod, a connecting gear 12, a third driving gear 16, a first bevel gear 14 and a second bevel gear 15. The foot pad 25 is arranged behind the main door panel 1 and below the door opening. The foot pad 25 is provided with a brush plate 26, which is arranged in an inclined shape and is arranged at the lower end of the foot pad 25. The connecting gear 12 is respectively engaged with the second half-tooth gear 9 and the third driving gear 16. The third driving gear 16 is connected to the first bevel gear 14, and the second bevel gear 15 is engaged with the first bevel gear 14. One end of the third driving rod is connected to the foot pad 25, and the other end is connected to the second bevel gear 15.

[0055] It should be noted that when the first half-toothed gear 6 is engaged with the first drive gear 7, the second half-toothed gear 9 is not engaged with the second drive gear 10, but the second half-toothed gear 9 is engaged with the connecting gear 12. In other words, the drive motor 11 drives the first half-toothed gear 6 to engage with the first drive gear 7, driving the pet door 2 to open. At the same time, the drive motor 11 drives the second half-toothed gear 9 to engage with the connecting gear 12, driving the footrest 25 to rotate and rise.

[0056] Generally, the number of teeth of the second half-toothed gear 9 is equal to half of the number of teeth of the third driving gear 16, so that the second half-toothed gear 9 can drive the foot pad 25 to rotate 90°, that is, drive the foot pad to rotate from a vertical state to a horizontal state.

[0057] In some embodiments, the separation component also includes a fixed curved block 24 and a foot pad. The fixed curved block 24 is installed on the back of the main door panel 1. The fixed curved block 24 is provided with an arc-shaped inner groove. The upper end of the foot pad 25 is provided with an arc-shaped outer protrusion 17. The outer protrusion 17 is embedded in the inner groove. The foot pad is laid on the foot pad 25. The upper end of the foot pad is placed in the inner groove and is pressed by the outer protrusion 17.

[0058] After the pet door panel 2 is opened, a pet enters through the door opening and steps onto the footrest 25. The pet's paw rubs against the pet's footpad, separating any dust and stone particles from the pet's paw. This prevents dust and stone particles from easily clinging to the pet's soles when the pet is outdoors. The brush plate 26 cleans the pet's paw, further improving the separation of dust and stone particles. Meanwhile, the fixed curved block 24 compresses the footpad, preventing it from sliding due to the pet's paw, which could affect the separation effect. This also facilitates replacement of the pet's footpad.

[0059] In addition, if Figure 9 As shown, an embodiment of the present invention further provides a smart pet door identification system, which includes the above-mentioned smart pet door, and further includes a camera 30 and a controller.

[0060] It is arranged on the front side of the main door panel 1 and located above the door opening. As in this embodiment, the camera 30 is specifically arranged at a position just above the door opening.

[0061] The controller is connected to the camera 30 and the drive motor 11 respectively, and is used to obtain image information in front of the main door panel 1 through the camera 30, and control the operation of the translation component according to the image information:

[0062] When it is determined that there is an animal in the image information, the drive motor 11 is controlled to drive the second half-tooth gear 9 to rotate, so that the second drive gear 10 drives the pet push plate 3 to move outward, the movable buckle opens, the pet push plate 3 is separated from the pet door panel 2, and the pet push plate 3 pushes the animal in front of the main door panel 1 to move outward to a predetermined area; when determining whether there is an animal in the image information, the judgment is made by comparing the body shape, hair color, facial features, etc. stored in the controller database.

[0063] The controller obtains an image of an animal in a predetermined area by the camera 30 and determines whether the image of the animal matches a target pet;

[0064] If they match, the drive motor 11 is controlled to drive the first half-tooth gear 6 to rotate, so that the first drive gear 7 drives the pet door panel 2 to move outward, and the movable snap lock connects the pet door panel 2 with the pet push plate 3. The pet door panel 2 drives the pet push plate 3 to move outward together to open the door opening, and the pet can enter the room through the door opening; and while the drive motor 11 drives the first half-tooth gear 6 to rotate, it drives the second half-tooth gear 9 to engage with the connecting gear 12, and then drives the first bevel gear 14 and the second bevel gear 15 to engage and transmit through the third drive gear 16 to drive the foot pad 25 to rise.

[0065] After the pet enters the room, the driving motor 11 is controlled to drive the first half-tooth gear 6 and the second half-tooth gear 9 to rotate, and the pet door panel 2 drives the pet push plate 3 to rotate inward back to the initial position, blocking the door opening, and the foot pad 25 falls.

[0066] If they do not match, the driving motor 11 is controlled to drive the second half-tooth gear 9 to rotate, so that the second driving gear 10 drives the pet push plate 3 to move inwardly back to the initial position to block the door opening.

[0067] In this document, directional terms such as front, back, top, and bottom are defined based on the positions of components in the accompanying drawings and relative to each other, and are intended for clarity and convenience in describing the technical solution. It should be understood that these terms are relative and may vary depending on usage and placement. The use of these directional terms should not limit the scope of protection claimed in this application.

[0068] The above embodiments and features of the embodiments may be combined with each other unless they conflict. The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
