Description

A pet door with a locking mechanism and a method for controlling the pet door. Technical Field

[0001] This invention belongs to the field of pet management technology, and relates to a pet door, and more particularly to a pet door with a locking mechanism and a pet door control method. Background Technology

[0002] Many people now keep pets, some because of hobby, and some because they need companionship. Pets not only need food, water, and shelter, but also often need entertainment and walks, especially for more active pets. If you have to keep opening and closing the door for your pet, it will be very troublesome. Therefore, some pet doors have appeared on the market.

[0003] For example, a utility model patent with application number CN202221964085.1 provides a door with a pet door, including a door body and a pet door. The door body has a cavity with a first axis horizontally arranged. The pet door is rotatably connected to the cavity through the first axis. The lower outer wall of the pet door slides in contact with the cavity, and the upper outer wall of the pet door slides in contact with the cavity. The cavity has anti-sway structures on both sides, including rollers, weights, and brackets. The door body has first protrusions on both sides above the cavity, with limit rings on the first protrusions. The brackets are slidably connected to the limit rings, and a weight is fixed above the brackets. The door body has a second protrusion above the weight, with a touch button above the second protrusion. The door body has an electric bell. The brackets are rotatably connected to the lower side through the second axis. The pet door has third protrusions on both sides above the upper part, with an upward-facing slope on the third protrusion. The rollers abut against the slope, and the slope pushes the anti-sway structures upward when the pet door is opened.

[0004] Existing technical solutions can only passively open and close pet doors, leaving the pet with the power to decide whether to open or close them. They cannot lock the pet door's open / closed state to prevent outside pets from entering or pets from escaping, thus leaving considerable room for improvement. Technical issues

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a pet door with a locking mechanism and a pet door control method. Technical solutions

[0006] The objective of this invention can be achieved through the following technical solution: a pet door with a locking mechanism, comprising:

[0007] A door frame, including the interior of a door, wherein the door frame is provided with a locking hole;

[0008] The door body includes a rotating side and a limiting side. The door body is rotatably connected to the door frame via the rotating side. The door body can rotate toward the inside of the door. The locking hole is located between the inside of the door and the door body.

[0009] A first locking mechanism is disposed in the door frame and located inside the door and between the door body. The first locking mechanism includes a locking seat and a locking pin. The locking seat is located inside the door frame and can be raised and lowered relative to the door frame. The locking pin is connected to the locking seat and can extend or retract from the locking hole.

[0010] When the locking pin extends out of the locking hole, it can contact the limiting side, thereby restricting the door from rotating inward; when the locking pin retracts into the locking hole, the door can rotate freely inward.

[0011] In the pet door with a locking mechanism described above, the first locking mechanism further includes a driving element connected to the door frame, and the locking seat connected to the driving element. The driving element can drive the locking seat to rise and fall.

[0012] In the pet door with a locking mechanism described above, the first locking mechanism further includes a return spring. One end of the return spring contacts the door frame, and the other end of the return spring contacts the locking seat. The return spring pushes the locking seat and causes the locking pin to extend out of the locking hole.

[0013] In the above-mentioned pet door with a locking mechanism, the locking seat is provided with a pressure plate, the driving element includes a rotating shaft and an eccentric wheel, the rotating shaft is fixed relative to the door frame and can rotate around its own axis, the eccentric wheel is connected to the rotating shaft, the bottom of the eccentric wheel contacts the pressure plate, and the pressure plate is located between the eccentric wheel and the return spring.

[0014] In the aforementioned pet door with a locking mechanism, the driving element further includes a motor, which is connected to the door frame. The rotating shaft is connected to the output shaft of the motor, and the motor can drive the rotating shaft to rotate.

[0015] In the aforementioned pet door with a locking mechanism, the driving element includes an electric cylinder connected to the door frame, and the locking seat is connected to the output shaft of the electric cylinder. The electric cylinder can drive the locking seat to rise and fall.

[0016] In the aforementioned pet door with a locking mechanism, the door frame is further provided with a guide post, and the locking seat is provided with a guide hole. The guide post is slidably connected to the guide hole, thereby allowing the locking seat to be raised and lowered and connected to the door frame.

[0017] In the pet door with a locking mechanism described above, the guide post is provided with a limiting block, and the locking seat is also provided with a limiting groove. The limiting groove communicates with the guide hole, and the limiting block is located in the limiting groove and can move along the length direction of the limiting groove.

[0018] In the aforementioned pet door with a locking mechanism, the door frame also includes an outer door, and the door body is located between the inner door and the outer door, and the door body can rotate toward the inner door or the outer door.

[0019] In the pet door with a locking mechanism described above, a second locking mechanism is also included, which is disposed on the door frame and located outside the door between the door and the door body. The structure of the second locking mechanism is the same as that of the first locking mechanism.

[0020] When the locking pin of the second locking mechanism extends out of the locking hole, the locking pin of the second locking mechanism can contact the limiting side, thereby restricting the door body from rotating outward; when the locking pin of the second locking mechanism retracts into the locking hole, the door body can rotate freely outward.

[0021] The pet door with a locking mechanism described above also includes a remote control system, which is used to communicate with the drive element of the second locking mechanism and to control whether the drive element of the second locking mechanism is working.

[0022] The pet door with a locking mechanism described above also includes a pet facial recognition system. The pet facial recognition system is connected to the door frame and located outside the door. The pet facial recognition system is communicatively connected to the drive element of the first locking mechanism and is used to recognize the pet's face to control whether the drive element works.

[0023] A pet door control method is also provided, including a pet door with a locking mechanism, and further including the method:

[0024] The remote control system is timed and divided into access control time and free time. During access control time, the remote control system automatically controls the motor of the second locking mechanism to extend the locking pin out of the locking hole, thereby restricting the door from rotating outward. During free time, the remote control system automatically controls the motor of the second locking mechanism to retract the locking pin into the locking hole, thereby allowing the door to rotate freely outward.

[0025] Temporary control is performed in the remote control system to control the motor of the second locking mechanism, thereby causing the locking pin to extend or retract into the locking hole.

[0026] In the above-mentioned pet door control method, a pet face recognition system is also included. The pet face recognition system is connected to the door frame and located outside the door. The pet face recognition system is electrically connected to the motor and is used to recognize the pet's face to control whether the motor works or not. The pet face 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 or not.

[0027] It also includes methods:

[0028] Known pet faces are entered into the remote control system. When the pet face recognition system recognizes an unfamiliar pet face, it automatically controls the motor of the first locking mechanism to extend the locking pin out of the locking hole, thereby restricting the door from rotating inward. When the pet face recognition system recognizes a known pet face, it automatically controls the motor of the first locking mechanism to retract the locking pin into the locking hole, thereby allowing the door to rotate freely inward.

[0029] Temporary control is performed in the remote control system to control the motor of the second locking mechanism, thereby causing the locking pin to extend or retract into the locking hole. Beneficial effects

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. The door body is restricted from rotating inward and outward by the first locking mechanism and the second locking mechanism respectively. The locking pin is extended or retracted into the locking hole by manual or automatic means, thereby locking the pet door in the open and closed state and restricting the entry of outside pets or the escape of pets in the house.

[0032] 2. The return spring pushes the locking seat and causes the locking pin to extend out of the locking hole. Therefore, under normal circumstances, the locking pin can contact the limit side to restrict the door from rotating inward or outward, thus playing a safety protection role and restricting outside pets from entering or pets from escaping.

[0033] 3. The pressure plate is located between the eccentric wheel and the return spring. Therefore, when the return spring pushes the locking seat, it will press against the eccentric wheel and rotate around its own axis with the rotating shaft. This rotation of the eccentric wheel will drive the locking seat to make reciprocating linear motion through the pressure plate, so as to realize the extension or retraction of the locking pin into the locking hole.

[0034] 4. The rotating shaft is fixedly connected to the output shaft of the motor, and the motor can drive the rotating shaft to rotate, thereby realizing automatic control of the rotating shaft.

[0035] 5. The access control time and free time can be preset through the remote control system to manage the opening and closing of the pet door facing outward. At the same time, the motor of the second locking mechanism can be temporarily controlled through the remote control system to make the locking pin extend or retract into the locking hole.

[0036] 6. The pet facial recognition system can be used to manage the opening and closing of the pet door, allowing it to face inwards.

[0037] 7. Link the remote control system with the pet facial recognition system. Known pet faces can be entered or deleted through the remote control system, thereby adjusting the pet facial recognition system in real time. At the same time, the motor of the first locking mechanism can be temporarily controlled through the remote control system to extend or retract the locking pin into the locking hole.

[0050] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.

[0051] As shown in Figures 1-6, a pet door with a locking mechanism includes: a door frame 100, a door body 200, and a first locking mechanism 300.

[0052] The door frame 100 includes a door interior 110 and is provided with a locking hole 130.

[0053] The door body 200 includes a rotating side 210 and a limiting side 220. The door body 200 is rotatably connected to the door frame 100 through the rotating side 210. 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 disposed between the door interior 110 and the door body 200, and between the door exterior 120 and the door body 200.

[0054] The first locking mechanism 300 is disposed in the door frame 100 and 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 inside 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 can extend or retract from the locking hole 130.

[0055] 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 restrict 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.

[0056] Specifically, the extension or retraction of the locking pin 320 into the locking hole 130 can be controlled manually or automatically, without being specifically limited here.

[0057] In this embodiment, the first locking mechanism 300 restricts the door 200 from rotating toward the inside 110 of the door, and the locking pin 320 is manually or automatically extended or retracted into the locking hole 130, thereby locking the pet door in the open / closed state and restricting outside pets from entering.

[0058] As shown in Figures 1-6, based on the above embodiments, the first locking mechanism 300 further includes a driving element, which is connected to the door frame 100, and the locking seat 310 is connected to the driving element. The driving element can drive the locking seat 310 to rise and fall.

[0059] As shown in Figures 1-6, based on the above embodiment, the first locking mechanism 300 further includes a return spring 330. One end of the return spring 330 contacts the door frame 100, and the other end of the return spring 330 contacts the locking seat 310. The return spring 330 pushes the locking seat 310 and drives the locking pin 320 to extend out of the locking hole 130.

[0060] 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 restrict the door body 200 from rotating toward the inside 110 or the outside 120 of the door, thus playing a safety protection role and restricting outside pets from entering or pets from escaping from the house.

[0061] As shown in Figures 1-6, based on the above embodiment, the locking seat 310 is provided with a pressure plate 311, and the driving element 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 bottom of the eccentric wheel 350 contacts the pressure plate 311. The pressure plate 311 is located between the eccentric wheel 350 and the return spring 330.

[0062] Specifically, the rotation of the rotating shaft 340 around its own axis can be controlled manually or automatically, without being specifically limited here.

[0063] In this embodiment, the pressure plate 311 is located between the eccentric wheel 350 and the return spring 330. Therefore, when the return spring 330 pushes the locking seat 310, it will press against the eccentric wheel 350 and rotate with the rotating shaft 340 around its own axis, causing the eccentric wheel 350 to rotate. This will cause the locking seat 310 to reciprocate linearly through the pressure plate 311, so as to realize that the locking pin 320 extends or retracts into the locking hole 130.

[0064] As shown in Figures 1-6, based on the above embodiments, the driving element further includes a motor 360, which is connected to the door frame 100. The rotating shaft 340 is connected to the output shaft of the motor 360, and the motor 360 can drive the rotating shaft 340 to rotate.

[0065] As an alternative (not shown), the driving element includes an electric cylinder connected to the door frame 100, and the locking seat 310 is connected to the output shaft of the electric cylinder, which can drive the locking seat 310 to rise and fall.

[0066] In this embodiment, the rotating shaft 340 is fixedly connected to the output shaft of the motor 360, and the motor 360 can drive the rotating shaft 340 to rotate, thereby realizing automatic control of the rotating shaft 340.

[0067] As shown in Figures 1-6, based on the above embodiments, the door frame 100 is further provided with a guide post 140, and the locking seat 310 is provided with a guide hole 312. The guide post 140 is slidably connected to the guide hole 312, thereby allowing the locking seat 310 to be raised and lowered and connected to the door frame 100.

[0068] In this embodiment, the guide post 140 is slidably connected to the guide hole 312 so that the locking seat 310 can be raised and lowered to be connected to the door frame 100. This guides the raising and lowering of the locking seat 310 relative to the door frame 100, thereby limiting the movement direction of the locking pin 320 and keeping it always aligned with the locking hole 130.

[0069] As shown in Figures 1-6, based on the above embodiments, the guide post 140 is provided with a limiting block 141, and the locking seat 310 is also provided with a limiting groove 313. The limiting groove 313 communicates with the guide hole 312, and the limiting block 141 is located in the limiting groove 313 and can move along the length direction of the limiting groove 313.

[0070] In this embodiment, the limiting block 141 is located in the limiting groove 313 and can move along the length direction of the limiting groove 313. It assists the locking seat 310 in raising and lowering relative to the door frame 100 and plays a guiding role. At the same time, the limiting block 141 can contact the limiting groove 313 to limit the range of motion of the locking seat 310.

[0071] As shown in Figures 1-6, based on the above embodiments, the door frame 100 further includes a door exterior 120, and 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.

[0072] Specifically, it also includes a second locking mechanism 500, which is disposed on the door frame 100 and 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.

[0073] More specifically, when the locking pin 320 of the second locking mechanism 500 extends out of the locking hole 130, the locking pin 320 of the second locking mechanism 500 can contact the limiting side 220 to restrict the door body 200 from rotating toward the outside of the door 120; when the locking pin 320 of the second locking mechanism 500 retracts into the locking hole 130, the door body 200 can rotate freely toward the outside of the door 120.

[0074] In this embodiment, the second locking mechanism 500 restricts the door 200 from rotating toward the outside 120, and the locking pin 320 is manually or automatically extended or retracted into the locking hole 130, thereby locking the pet door in the open / closed state and preventing pets from escaping from the house.

[0075] As shown in Figures 1-6, based on the above-described embodiments, a remote control system (not shown in the figures) is also included. The remote control system is used to communicate with the motor 360 of the second locking mechanism 500 and to control whether the motor 360 of the second locking mechanism 500 works.

[0076] Specifically, the remote control system can be an application software on a mobile phone.

[0077] In this embodiment, the door opening and closing of the pet door facing outward 120 can be managed by preset access control time and free time through the remote control system. At the same time, the motor 360 of the second locking mechanism 500 can be temporarily controlled by the remote control system to extend or retract the locking pin 320 into the locking hole 130.

[0078] As shown in Figures 1-6, based on the above embodiments, a pet face recognition system 400 is also included. The pet face recognition system 400 is connected to the door frame 100 and located outside the door 120. The pet face recognition system 400 is electrically connected to the motor 360 and is used to recognize the pet's face to control whether the motor 360 works.

[0079] In this embodiment, the pet door facing inward 110 can be managed by the pet facial recognition system 400.

[0080] As shown in Figures 1-6, a pet door control method includes a pet door with a locking mechanism, and further includes the following method:

[0081] The remote control system is timed and divided into access control time and free time. During access control time, the remote control system automatically controls the motor 360 of the second locking mechanism 500 to extend the locking pin 320 out of the locking hole 130, thereby restricting the door 200 from rotating outward 120. During free time, the remote control system automatically controls the motor 360 of the second locking mechanism 500 to retract the locking pin 320 into the locking hole 130, thereby allowing the door 200 to rotate freely outward 120.

[0082] Temporary control is performed in the remote control system to control the motor 360 of the second locking mechanism 500, thereby causing the locking pin 320 to extend or retract into the locking hole 130.

[0083] In this embodiment, the door opening and closing of the pet door facing outward 120 can be managed by preset access control time and free time through the remote control system. At the same time, the motor 360 of the second locking mechanism 500 can be temporarily controlled by the remote control system to extend or retract the locking pin 320 into the locking hole 130.

[0084] As shown in Figures 1-6, based on the above embodiments, a pet face recognition system 400 is also included. The pet face recognition system 400 is connected to the door frame 100 and located outside the door 120. The pet face recognition system 400 is electrically connected to the motor 360 and is used to recognize the pet's face to control whether the motor 360 works. The pet face recognition system 400 is communicatively connected to the remote control system. The remote control system is communicatively connected to the motor 360 of the first locking mechanism 300 and is used to control whether the motor 360 of the first locking mechanism 300 works.

[0085] It also includes methods:

[0086] When a known pet face is entered into the remote control system, and the pet face recognition system 400 recognizes an unfamiliar pet face, the pet face recognition system 400 automatically controls the motor 360 of the first locking mechanism 300 to extend the locking pin 320 out of the locking hole 130, thereby restricting the door 200 from rotating toward the door interior 110; when the pet face recognition system 400 recognizes a known pet face, the pet face recognition system 400 automatically controls the motor 360 of the first locking mechanism 300 to retract the locking pin 320 into the locking hole 130, thereby allowing the door 200 to rotate freely toward the door interior 110;

[0087] Temporary control is performed in the remote control system to control the motor 360 of the second locking mechanism 500, thereby causing the locking pin 320 to extend or retract into the locking hole 130.

[0088] In this embodiment, the pet door facing inward 110 can be managed by the pet facial recognition system 400.

[0089] It is also worth noting that by linking the remote control system with the pet facial recognition system 400, known pet faces can be entered or deleted through the remote control system, thereby adjusting the pet facial recognition system 400 in real time. At the same time, the motor 360 of the first locking mechanism 300 can be temporarily controlled through the remote control system, thereby causing the locking pin 320 to extend or retract into the locking hole 130.

A pet door with locking mechanism as claimed in claim 9 wherein: It also includes a second locking mechanism, which is disposed on the door frame and located outside the door and between the door body. The structure of the second locking mechanism is the same as that of the first locking mechanism. When the locking pin of the second locking mechanism extends out of the locking hole, the locking pin of the second locking mechanism can contact the limiting side, thereby restricting the door body from rotating outward; When the locking pin of the second locking mechanism retracts into the locking hole, the door can rotate freely outward.

11. A pet door with locking mechanism as claimed in claim 10 wherein: It also includes a remote control system, which is used to communicate with the drive element of the second locking mechanism and to control whether the drive element of the second locking mechanism is working.

12. A pet door with locking mechanism as claimed in claim 9 wherein: It also includes a pet facial recognition system, which is connected to the door frame and located outside the door. The pet facial recognition system is communicatively connected to the drive element of the first locking mechanism and is used to recognize the pet's face to control whether the drive element works.

13. A pet gate control method, characterized by, Including a pet door with a locking mechanism as described in claim 11, and further including a method: The remote control system is timed and divided into access control time and free time. During access control time, the remote control system automatically controls the drive element of the second locking mechanism to extend the locking pin out of the locking hole, thereby restricting the door from rotating outward. During free time, the remote control system automatically controls the drive element of the second locking mechanism to retract the locking pin into the locking hole, thereby allowing the door to rotate freely outward. Temporary control is performed in the remote control system to control the drive element of the second locking mechanism, thereby causing the locking pin to extend or retract into the locking hole.

14. A pet gate control method as described in claim 13, wherein: It also includes a pet facial recognition system, which is connected to the door frame and located outside the door. The pet facial recognition system is electrically connected to the drive element and is used to recognize the pet's face to control whether the drive element works. The pet facial recognition system is communicatively connected to the remote control system. The remote control system is communicatively connected to the drive element of the first locking mechanism and is used to control whether the drive element of the first locking mechanism works. It also includes methods: Known pet faces are entered into the remote control system. When the pet face recognition system recognizes an unfamiliar pet face, it automatically controls the drive element of the first locking mechanism to extend the locking pin out of the locking hole, thereby restricting the door from rotating inward. When the pet facial recognition system recognizes a known pet face, it automatically controls the drive element of the first locking mechanism to retract the locking pin into the locking hole, thereby allowing the door to rotate freely inward. Temporary control is performed in the remote control system to control the drive element of the second locking mechanism, thereby causing the locking pin to extend or retract into the locking hole.
