Description

Technical Field

[0001] This invention relates to the field of pet home technology, and in particular to a pet door. Background Technology

[0002] In modern society, more and more people are keeping small pets such as cats and dogs, leading to a growing market for pet furniture. Pet doors, a type of pet furniture, are primarily used to open and close the entrance to a pet's dwelling, allowing pets to enter or exit, or to keep them inside. With scientific advancements, traditional manual pet doors are gradually evolving towards intelligent systems.

[0003] Current smart pet doors use electric components such as motors, telescopic rods, or other electric components to open and close the doorway to the pet's enclosure. Furthermore, current smart pet doors are typically single-piece doors, making them quite heavy and requiring significant energy to operate electrically. Moreover, current smart pet doors only have two states: open and closed. When closed, they are locked with a door lock, limiting their functionality and resulting in poor anti-following capabilities. This means that once a pet enters, other animals outside can easily follow it in. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, the present invention provides a pet door, comprising: Door frame; A door panel is installed inside the door frame and used to seal the door frame. The door panel includes an upper panel and a lower panel. The upper part of the upper panel is hinged to the upper part of the door frame, and the upper part of the lower panel is hinged to the lower part of the upper panel. A door lock assembly is installed on the door frame, the door lock assembly being used to lock the door panel to the door frame; A rotating rod is rotatably mounted on the upper part of the door frame, and the rotating rod is connected to a rotating drive component; A lever is fixed to the middle of the rotating rod, and the lever is used to move the upper plate. A connector is provided between the door lock assembly and the rotating rod to enable the door lock assembly to be linked with the rotating rod. In the first state, the lever is located away from the upper plate, and the door panel is completely locked to the door frame by the door lock assembly, so the pet door is in a locked state where it cannot enter or leave. In the second state, the lever is turned to a position close to the upper plate, and the door panel is partially locked to the door frame by the door lock assembly, and the pet door is in a state where it can be pushed outwards but not inwards. In the third state, the lever pushes the upper plate outward and the door lock assembly is fully unlocked, and the pet door is in an open state where it can be entered and exited.

[0005] Furthermore, in order to better realize the present invention, the upper two sides of the upper plate are respectively rotatably connected to the inner walls of the upper two sides of the door frame through two round shafts, so that the upper part of the upper plate is hinged to the upper part of the door frame; The upper plate has a protruding plate located inside the door on both sides of its lower part, and the lower plate has a protruding platform located inside the door on both sides of its upper part. The two protruding platforms are respectively hinged to the two protruding plates through two rotating shafts, so that the upper part of the lower plate is hinged to the lower part of the upper plate. In the first and second states, the bottom surface of the upper plate is in contact with the top surface of the lower plate.

[0006] Furthermore, to better realize the present invention, the door lock assembly includes: Door bolts are installed on both sides of the door frame. Locking grooves for matching the door bolts are opened on both sides of the lower plate near the outer wall of the door. The door bolts on both sides of the door frame are connected to the rotating rod through two connecting pieces respectively. Fixed baffles are installed on both sides of the door frame, and the fixed baffles are used to block the lower plate from the inside of the door; In the first state, the bolt is inserted into the lock groove, the lower plate is in contact with the fixed baffle, and the lower plate is clamped between the bolt and the fixed baffle. In the second state, the rotating rod drives the bolt out of the lock groove through the connector, and the lower plate fits against the fixed baffle. In the third state, the lower plate moves to the side above the fixed baffle under the action of the upper plate.

[0007] Furthermore, in order to better realize the present invention, the middle part of the door bolt is rotatably connected to the door frame via a round rod, one end of the door bolt is connected to the door frame via a tension spring, the connecting piece is connected between the other end of the door bolt and the rotating rod, and both the tension spring and the rotating rod are located above the door bolt.

[0008] Furthermore, in order to better realize the present invention, the connector is a taut flexible connecting rope, the rotating rod is provided with an outward protruding joint, one end of the flexible connecting rope is connected to the outward protruding joint, the other end of the door bolt is provided with an outward protruding post, and the other end of the flexible connecting rope is connected to the outward protruding post.

[0009] Furthermore, in order to better realize the present invention, the rotation drive is a motor; The door frame is also equipped with a recognition module on the outside side of the door, which is used to identify the appearance characteristics of a preset pet. It also includes a control module, which is electrically connected to both the identification module and the motor, to control the operating state of the motor based on the identification result of the identification module.

[0010] Furthermore, in order to better realize the present invention, the recognition module is a camera.

[0011] Furthermore, in order to better realize the present invention, an infrared scanning module located inside the door is also installed on the top of the door frame. The infrared scanning module is electrically connected to the control module. After the infrared scanning module detects that a pet has passed through, the control module drives the motor to switch the pet door back to the second state or the first state.

[0012] Furthermore, to better realize the present invention, the door frame is also equipped with a photoelectric sensor, which is used to sense the position of the upper plate and the door bolt, and the photoelectric sensor is electrically connected to the control module. The control module determines whether the door is open or locked based on the feedback result of the photoelectric sensor.

[0013] Furthermore, in order to better realize the present invention, the control module integrates a signal receiver, which is communicatively connected to a remote terminal.

[0014] The beneficial effects of this invention are reflected in the fact that by setting the door panel as a hinged upper and lower plate, with the upper plate hinged to the upper part of the door frame, and by setting a rotating drive member to drive the rotating rod to rotate, the rotating rod drives the lever to rotate to push the upper plate, and the door lock assembly locking the door panel is linked with the rotating rod, thus making the pet door have three states. In the first state, the lever is in a position away from the upper plate, and the door panel is completely locked to the door frame by the door lock assembly, the pet door is in a locked state where it cannot enter or exit; in the second state, the lever is rotated to a position close to the upper plate, and the door panel is partially locked to the door frame by the door lock assembly, the pet door is in a state where it can be pushed open outwards but not inwards; in the third state, the lever pushes the upper plate outwards, the pet door is in an open state where it can enter and exit. In the first state, the pet cannot pass through the door panel; in the second state, the pet inside the door can pass through the door panel to reach the outside, but animals outside the door cannot pass through the door panel to enter; in the third state, the pet can freely pass through the door panel to enter and exit.

[0015] In this way, the rotating drive only needs to rotate the lever to control the state of the pet door. To open the door, only the upper panel needs to be moved; the lower panel moves under the influence of the upper panel and gravity, allowing the door to open fully. Therefore, the rotating drive only needs to handle the movement of the upper panel, resulting in a lower load compared to a single, solid door panel, thus making it more energy-efficient. Furthermore, when a pet passes through the door from the outside, the rotating drive can quickly transition the pet door from the third state to the second state, preventing other animals from easily following the pet inside. As the pet enters, it will push the lower panel inwards; after the pet passes through, the lower panel will rotate downwards under its own weight, further blocking other animals from following and enhancing the anti-following effect.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: Reference Figures 1-9 As shown, the pet door provided in this embodiment includes a door frame 100, a door panel 200, a door lock assembly, a rotating rod 500, a lever 510, and a connector 700, wherein: The door frame 10 can be installed at the door opening using expansion bolts. The door frame 100 consists of two interlocking and bolted frames for easy assembly and disassembly. The inner opening of the door frame 100 forms a doorway for pets to enter and exit.

[0020] The door panel 200 is installed inside the door frame 100 and is used to block the doorway of the door frame 100. The door panel 200 includes an upper panel 210 and a lower panel 220. The upper part of the upper panel 210 is hinged to the upper part of the door frame 100, and the upper part of the lower panel 220 is hinged to the lower part of the upper panel 210. Thus, the door panel 200 is a foldable door. Specifically, the upper two sides of the upper plate 210 are rotatably connected to the inner walls of the upper two sides of the door frame 100 via two round shafts 211, so that the upper part of the upper plate 210 is hinged to the upper part of the door frame 100, thus allowing the upper plate 210 to rotate freely in the doorway of the door frame 100; the lower two sides of the upper plate 210 are respectively provided with a protruding plate 212 located inside the door, and the upper two sides of the lower plate 220 are respectively provided with a protruding platform 221 located inside the door. The two protruding platforms 221 are respectively hinged to the two protruding plates 212 via two rotating shafts 222, so that the upper part of the lower plate 220 is hinged to the lower part of the upper plate 210.

[0021] A door lock assembly is installed on the door frame 100, and the door lock assembly is used to lock the door panel 200 to the door frame 100.

[0022] A rotating rod 500 is rotatably mounted between the upper two sides of the door frame 100. The rotating rod 500 is connected to a rotation drive component, which drives the rotating rod 500 to rotate. A lever 510 is integrally formed or hot-melt connected and fixed to the middle of the rotating rod 500. Optionally, the lever 510 extends radially along the rotating rod 500. The number of rotating rods 500 can be one, two, or more. The lever 510 is used to actuate the upper plate 210. A connector 700 connects the door lock assembly and the rotating rod 500, enabling the door lock assembly and the rotating rod 500 to move together.

[0023] The pet gate has at least three states: a first state, a second state, and a third state. First state: The lever 510 is in a position away from the upper plate 210, the door panel 200 is completely locked to the door frame 100 by the door lock assembly, and the pet door is in a locked state where it cannot enter or leave. Second state: When lever 510 is turned to a position close to upper plate 210, door panel 200 is partially locked to door frame 100 by door lock assembly, and pet door is in a state where it can be pushed outwards but not inwards. Third state: The lever 510 pushes the upper plate 210 outward and the door lock component is unlocked, and the pet door is in an open state where it can be entered and exited.

[0024] It is easy to understand that by rotating the drive component to drive the rotating rod 500 to rotate, one can switch back and forth between the first state, the second state, and the third state. Specifically, when the lever 500 is not initially rotating, the pet door is in the first state, at which point the lever 510 is away from the upper plate 210 and the door lock assembly locks the door panel 200 to the door frame 100. When the lever 500 rotates forward to the first angle, it drives the lever 510 to rotate to a position close to the upper plate 210. At this point, the door panel 200 is partially locked to the door frame 100 by the door lock assembly. When the lever 500 continues to rotate forward to the second angle, it drives the lever 510 to push the upper plate 210 outward. At this point, the door lock assembly is fully unlocked. When the upper plate 210 is pushed outward by the lever 510, because the upper plate 210 and the lower plate 220 are hinged, the lower plate 220 will be pulled up by the upper plate 210 and its own weight. In the third state, the lower plate 220 is placed vertically outside the door frame 100. In the first and second states described above, the bottom surface of the upper plate 210 is in contact with the top surface of the lower plate 220. Thus, in the third state, a pet outside the door can push against the lower plate 220 from the outside, causing it to rotate inwards and enter the door. Once the pet is inside, the rotating drive mechanism drives the rotating rod 500 to rotate, allowing the pet door to quickly switch from the third state to the second state. When it is necessary to lock the pet inside, the rotating drive mechanism continues to rotate, allowing the pet door to quickly switch from the second state to the first state.

[0025] The pet door provided in this embodiment is configured with a hinged upper plate 210 and a lower plate 220 for the door panel 200. The upper plate 210 is hinged to the upper part of the door frame 100. A rotating drive is provided to drive the rotating rod 500 to rotate. The rotating rod 500 drives the lever 510 to rotate and push the upper plate 210. The door lock assembly that locks the door panel 200 is linked with the rotating rod 500, so that the pet door has the above three states. Obviously, in the first state, the pet cannot pass through the door panel 200; in the second state, the pet inside the door can pass through the door panel 200 to reach the outside, but animals outside the door cannot pass through the door panel 200 to enter the inside; in the third state, the pet can freely pass through the door panel 200 to enter and exit.

[0026] In this way, the rotation drive only needs to drive the rotating rod 500 to rotate to control the state of the pet door. When opening the door, only the upper plate 210 needs to be moved. The lower plate 220 moves under the action of the upper plate 210 and gravity, so that the door panel 200 is fully opened. Therefore, the rotation drive only needs to load the upper plate 210. Compared with a whole door panel 200, the load of the rotation drive is obviously lower, thus saving more energy. Moreover, when the pet passes through the door panel 200 from the outside to enter the door, the rotation drive can be used to quickly change the pet door from the third state to the second state, so that animals outside cannot easily follow the pet into the door. When the pet enters the door, it will push the lower plate 220 inward. After the pet passes through the door panel 200, the lower plate 220 will rotate downward under its own weight, thus blocking other animals from following in and improving the anti-following effect.

[0027] Optionally, the aforementioned door lock assembly includes a bolt 300 and a fixing plate 400, wherein: Door bolts 300 are installed on both sides of the door frame 100. Lock grooves 223 for matching the door bolts 300 are provided on both sides of the outer wall of the lower plate 220 near the outside of the door. The door bolts 300 on both sides of the door frame 100 are connected to the rotating rod 500 through two connectors 700 respectively. Fixed baffles 400 are installed on both sides of the door frame 100. The fixed baffles 400 are used to block the lower plate 220 from the inside of the door.

[0028] In the first state, the bolt 300 is inserted into the lock groove 223, the lower plate 220 is in contact with the fixed stop plate 400, and the lower plate 220 is clamped between the bolt 300 and the fixed stop plate 400. At this time, the bottom end face of the upper plate 210 is in contact with the top end face of the lower plate 220. In this case, the door panel 200 is completely locked to the door frame 100 by the door lock assembly.

[0029] In the second state, the rotating rod drives the bolt 300 out of the lock groove 223 via the connector 700, and the lower plate 220 is in contact with the fixed baffle 400. At this time, the bottom end face of the upper plate 210 is in contact with the top end face of the lower plate 220. In this way, even if the bolt 300 is moved out of the lock groove 223, the door panel 200 cannot be pushed to fold from the outside of the door; it can only be pushed to fold from the inside of the door.

[0030] In the third state, the lower plate 220 moves to the side above the fixed baffle 400 under the action of the upper plate 210. At this time, the lower plate 220 is completely disengaged from the door lock assembly, thereby realizing the complete unlocking of the door lock assembly.

[0031] It is worth noting that the bolt 300 moves together with the rotating rod 500 via the connector 700. Optionally, the middle of the bolt 300 is rotatably connected to the door frame 100 via a round rod 310, one end of the bolt 300 is connected to the door frame 100 via a tension spring 320, and the connector 700 connects the other end of the bolt 300 to the rotating rod 500. Both the tension spring 320 and the rotating rod 500 are located above the bolt 300. Thus, during the rotation of the rotating rod 500, the other end of the bolt 300 is pulled by the connector 700, causing the bolt 300 to rotate around the round rod 310, thereby causing the bolt 300 to rotate into or out of the lock groove 223. When the bolt 300 enters the lock groove 223, it cooperates with the fixed stop plate 400 to completely lock the door panel 200 to the door frame 100.

[0032] Optionally, the aforementioned connector 700 is a taut flexible connecting rope. The rotating rod 500 is provided with an outwardly protruding joint 520, one end of which is connected to the outwardly protruding joint 520. The other end of the door bolt 300 is provided with an outwardly protruding post 330, and the other end of the flexible connecting rope is connected to the outwardly protruding post 330. The flexible connecting rope is located inside the door frame 100.

[0033] Through the above structure, the bolt 300 and the rotating rod 500 are linked by a flexible connecting rope. When the rotating rod 500 rotates, the flexible connecting rope prevents the other end of the bolt 300 from loosening. At this time, the tension spring 320 applies tension to one end of the bolt 300, causing the bolt 300 to rotate. After the rotating rod 500 rotates to a certain angle, the bolt 300 rotates into the lock groove 223. Specifically, a lock block is provided at the other end of the bolt 300. The bolt 300 is inserted into the lock groove 223 for locking; in fact, the lock block on the bolt 300 rotates into the lock groove 223 for locking. The above locking assembly has the advantages of simple structure and reliable locking.

[0034] Optionally, the aforementioned rotation drive is a motor 600. A recognition module is also installed on the outside side of the door frame 100. This recognition module identifies preset pet appearance features and includes a control module. The control module is electrically connected to both the recognition module and the motor 600 to control the operation of the motor 600 based on the recognition result. Specifically, the recognition module is a camera 810, and the control module is a control unit integrated inside the camera 810. Alternatively, the control module can be a separate circuit board with integrated chips installed inside the door frame 100. Specifically, the camera 810 captures images of the pet's appearance or face, compares them with pre-stored features, and upon successful matching, the control module outputs an opening signal.

[0035] In this way, the camera 810 captures the appearance of the animal outside the door. Then, using image recognition technology, the controller controls the motor 600 to rotate when it recognizes the animal as its own pet. Before this, the pet door panel 200 is in the first state described above, i.e., the pet door is closed and locked. When the pet is recognized, the control module controls the motor 600 to quickly rotate to the second angle described above, opening the door. Other animals cannot open the pet door, improving the anti-following effect. It is worth noting that image recognition technology is existing technology, so it will not be described in detail here.

[0036] More preferably, an infrared scanning module 820 located inside the door is also installed at the top of the door frame 100. The infrared scanning module 820 is electrically connected to the control module. After the infrared scanning module 820 detects a pet passing through, the control module drives the motor 600 to switch the pet door back to the second or first state. Specifically, when the pet enters the door from outside, the pet door is in the third state. During the entry process, the pet will push against the lower plate 220, causing the lower plate 220 to rotate inward. At this time, the lower plate 220 blocks the infrared scanning module 820. When the pet is completely inside the door, the lower plate 220 rotates back and no longer blocks the infrared scanning module 820. At this time, it can be determined that the pet has completely entered the door. Then, the control module drives the motor 600 to rotate back, so that the pet door quickly switches from the third state back to the second state. If the pet exits from the door, the pet will pass under the infrared scanning module 820.

[0037] Optionally, the door frame 100 is also equipped with a photoelectric sensor. The photoelectric sensor is used to sense the position of the upper plate 210 and the door bolt 300. The photoelectric sensor is electrically connected to the control module, and the control module determines whether the door is properly opened or locked based on the feedback from the photoelectric sensor. In fact, there are two photoelectric sensors, namely a first photoelectric sensor 910 and a second photoelectric sensor 920. The first photoelectric sensor 910 is mounted on the door frame 100 and has two detection positions. A first protruding structure 213 is connected to the hinge shaft of the upper plate 210. When the first protruding structure 213 rotates to one of the detection positions of the first photoelectric sensor 910, it indicates that the upper plate 210 is fully open. The first photoelectric sensor 910 transmits signal A to the control module. At this time, the control module controls the motor 600 to stop rotating to prevent the motor 600 from rotating beyond the threshold angle when the door is opened. When the first protruding structure 213 rotates to the other detection position of the first photoelectric sensor 910, it indicates that the upper plate 210 is in the position of completely closing the door frame 100. At this time, the first photoelectric sensor 910 transmits signal B to the control module. The second photoelectric sensor 920 has only one detection position. This sensor is mounted on the door frame 100. The door bolt 300 has a second protruding structure 340. When the door bolt 300 is inserted into the lock slot 223 and locked, the second protruding structure 340 rotates to the detection position of the second photoelectric sensor 920. At this time, the second photoelectric sensor 920 sends a C signal to the control module. When the control module receives both the B and C signals simultaneously, it controls the motor 600 to stop rotating, preventing the motor 600 from rotating too much when closing the door. It is worth noting that photoelectric sensors are very existing technology. This embodiment only uses a photoelectric sensor in conjunction with the protruding structure to determine the rotation angle of the upper plate 210 and the door bolt 300. Therefore, the first and second photoelectric sensors will not be described in detail here.

[0038] Even better, the control module integrates a signal receiver that communicates with a remote terminal, allowing users to adjust the status of the pet door and monitor the pet's entry and exit via the remote terminal.
