Description

Smart automatic pet door

[0001] The present invention relates to a smart automatic pet door, and more specifically, to a smart automatic pet door that recognizes the approach of a pet and automatically opens and closes the exit, thereby ensuring excellent sealing performance and insulation effect, and thereby reducing heating costs, and further, can be easily adapted to and used by pets without any special training, and can prevent physical injury to pets by blocking safety accidents such as operating noise and getting caught.

[0002] Although the home is a confined space, even this is partitioned by doors, making it difficult for pets to move around smoothly. Therefore, to address the inconvenience of having to open and close doors every time a pet enters or leaves, a dedicated pet-access door was proposed.

[0003] For these types of entrances, you can consider opening up the existing door to a certain area and constructing a separate door with an opening large enough for pets to pass through, or making a dedicated entrance by appropriately utilizing the gap between the door or window in the structure of a sliding door or window frame.

[0004] Meanwhile, in the prior art, Patent No. 10-2278365 (Pet Door System) is a pet door system installed between the window frame and the opposing surface of the window, in a state where a protrusion is formed on the inner surface of a window frame, and a groove formed on the outer surface of a window that opens and closes in a sliding structure inside the window frame, the pet door system comprising: a fixed frame part supported on the lower side of the opposing surface of the window frame and the window; a movable frame part supported on the upper side of the opposing surface of the window frame and the window by rising while being overlapped with the fixed frame part; And an entrance door part rotatably provided at an end of the fixed frame part for a pet to enter and exit; wherein the 1-2 fixed vertical frames of the fixed frame part and the 1-2 movable vertical frames of the movable frame part are positioned in an opposed state, and a sliding protrusion having a ㅜ shape and a sliding groove on the opposite surface are mutually engaged so that the 1-2 movable vertical frame is raised and lowered from the 1-2 fixed vertical frame, and the outer opposite surfaces of the 1-2 fixed and movable vertical frames are respectively positioned adjacent to the opposite surfaces of the groove part of the window, and a coupling groove is formed in the height direction at set intervals on one surface of the movable frame part, and a locking part that is elastically engaged to always move forward is provided on the upper end of one surface of the fixed frame part, and an end of the locking part is coupled to one of the coupling grooves of the movable frame part to fix the position of the movable frame part.

[0005] In this prior art, the pet must forcefully open and close the door by directly pushing the entrance door part, which is provided with a rotatably fixed frame end, with the pet's head, etc. In this case, not only is noise generated due to collision with the entrance door part, but repeated impacts to the relatively hard entrance door part can cause harm to the pet's body. In addition, there is a risk of a body part getting caught in the entrance door part during the rotation operation of the entrance door part, so caution is required when using it.

[0006] In addition, if the entrance door itself is formed with a structure such as a soft film or membrane, the sealing power is reduced, which reduces the indoor heating and cooling effect and prevents the door from faithfully performing its function of actually isolating space.

[0030] To fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. These embodiments are provided to more completely explain the present invention to those with average knowledge in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that in each drawing, the same parts are sometimes depicted with the same reference numerals. Detailed descriptions of well-known functions and configurations that may unnecessarily obscure the gist of the present invention are omitted.

[0031] The smart automatic pet door (1, hereinafter referred to as a pet door) according to the present invention can be broadly defined as including a frame portion (10), a detection portion (20), a screen portion (30), a driving portion (40), and a control portion (not shown).

[0032] First, the frame part (10) is a frame structure that constitutes the overall skeleton of the pet door and supports the detection part (20), screen part (30), driving part (40), control part, etc. in the appropriate places.

[0033] The frame part (10) is installed in the gap between the existing door and the sliding door and the window frame or in the opening where a certain area is open to the outside, and forms a passage (R) that serves as a passage for the pet to enter the interior.

[0034] In this embodiment, the frame portion (10) can have a square frame structure, and on the left and right inner sides, a rail (11) for guiding the screen portion (30) to be described later can be formed to be long and recessed vertically.

[0035] The detection unit (20) is installed on the top of the frame unit (10) and is configured to detect the approach of a pet. It is provided as a pair of two units at the front and rear of the frame unit (10) and can detect a pet approaching from the front and rear directions of the pet door.

[0036] The detection unit (20) can detect when a pet approaches the pet door and generate a detection signal to transmit it to the control unit.

[0037] The detection unit (20) can use a sensor such as a known infrared sensor that can detect the approach of a pet.

[0038] The screen section (30) is configured to be connected to the frame section (10) in a way that it can move up and down and performs the function of opening and closing the passage (R), and is formed in the shape of a plate with a certain area so that the passage (R) can be selectively shielded.

[0039] For example, when the screen part (30) is pulled upward by the driving part (40) to be described later, the passage (R) can be opened, and when the screen part (30) is pulled downward, the passage (R) can be closed.

[0040] The left and right ends of the screen portion (30) are connected to the rail (11), and an operating hole (12) can be formed long left and right through the upper part of the frame portion (10) so that the screen portion (30) can pass through the upper part of the frame portion (10) without difficulty when moving upward.

[0041] The driving unit (40) is installed on the upper part of the frame unit (10) and performs the function of reciprocatingly pulling the screen unit (30) up and down.

[0042] To this end, the driving unit (40) may be exemplified by including an idle roller (41) that is installed on the upper part of the frame part (10) so as to be rotatable in place, a driving roller (42) that is positioned a certain distance in front of the idle roller (41) so that a screen part (30) is interposed between the idle roller (41), and a driving motor (43) that is connected to the driving roller (42) while installed on the upper part of the frame part (10) and drives the driving roller (42) to rotate in a forward and reverse direction.

[0043] That is, the screen portion (30) is interposed between the idle roller (41) and the drive roller (42) and can move up and down in conjunction with the rotation of the drive roller (42).

[0044] The control unit controls the driving unit (40) based on the detection result of the detection unit (20) to enable the opening and closing operation of the screen unit (30).

[0045] The control unit can operate based on the input of a detection signal provided from the detection unit (20).

[0046] The control unit electrically connects the operating motors of the detection unit (20) and the driving unit (40), and can be implemented using at least one of a processor, controller, microcontroller, microprocessor, or other electrical unit for performing functions mounted on the board, in a line that can control them in conjunction with each other. The installation location is also not particularly limited, so specific drawings and descriptions are omitted below.

[0047] In summary, when a pet is detected by the front or rear detection unit (20), the detection unit (20) transmits a detection signal to the control unit, and the control unit controls the drive motor (43) based on this detection signal to rotate the drive roller (42), so that the screen unit (30) interposed between the idle roller (41) and the drive roller (42) moves upward, thereby opening the passage (R). Accordingly, pet items pass through the opened passage (R), and the control unit can control the drive motor (43) in the reverse direction to close the passage (R) again when a predetermined time is exceeded while the passage (R) is open, so that the screen unit (30) that has moved upward returns to its original position.

[0048] Meanwhile, in the aforementioned embodiment, the size of the passageway (R) is fixed and cannot be adjusted separately. Therefore, if the size of the passageway (R) needs to be adjusted to suit the size of the pet due to changes in the growth or type of the pet, the existing pet door must be removed and a new pet door of the appropriate size must be installed, which inevitably incurs inconvenience and costs.

[0049] Accordingly, in the embodiment described below, the size of the passage (R) can be configured variably depending on the situation with one pet door.

[0050] In this embodiment, there are differences in some structures, such as the frame portion (10) and the driving portion (40), from the aforementioned embodiment. Hereinafter, descriptions of parts that are the same or similar to those of the aforementioned embodiment will be omitted, and only the parts that are different will be described in detail.

[0051] The pet door in this embodiment can be exemplified as including, as illustrated in FIGS. 6 to 12, a first frame portion (100), a second frame portion (200), a detection portion (20), a screen portion (30), a first driving portion (40), a second driving portion (50), a control portion, and a guide portion (60).

[0052] In this embodiment, the first frame part (100) and the second frame part (200) that perform the role of the frame part (10) in the above-described embodiment are configured to be divided from each other, and the distance between the divided first frame part (100) and the second frame part (200) can be adjusted to control the open area of ​​the passage (R).

[0053] More specifically, the first frame part (100) and the second frame part (200) have the same structure, but are arranged symmetrically left and right, and a passage (R) is provided between them.

[0054] First, the first frame section (100) can be exemplified as including a first rail frame (110), a first lower frame (120), and a first upper frame (130).

[0055] The first rail frame (110) is formed to be long and extend in the vertical direction, and may have a first rail (111) to which the left corner of the screen section (30) is connected in the inner direction facing the screen section (30).

[0056] Based on the first rail frame (110), the first upper frame (130) can be integrally connected to the upper part of the first rail frame (110), and the first lower frame (120) can be integrally connected to the lower part of the first rail frame (110).

[0057] The first lower frame (120) constitutes the lowest part of the first frame section (100) and may be formed as a long bar-shaped structure extending a certain length in the direction of the second frame section (200) facing the lower part of the first rail frame (110).

[0060] The first upper frame (130) is a plate-shaped structure formed to extend a certain length in the direction of the second frame portion (200) facing parallel to the first lower frame (120) from the upper end of the first rail frame (110), and can support the first driving portion (40) to be described later.

[0061] A pair of first lateral support members (131) are formed to protrude and face each other on the left and right ends of the first upper frame (130), and a first rear support member (132) is formed at the rear end to connect the pair of first lateral support members (131), thereby forming a body structure in which the front and a portion of the upper part are opened above the first upper frame (130), and a first finishing cover (133) is detachably mounted on the open front and upper part, thereby forming a body structure having an internal space approximately above the first upper frame (130). A first driving unit (40) can be installed in the internal space of the body thus configured.

[0062] A first operating hole (140) may be continuously cut and formed in the first upper frame (130) and the first side support (131) so that the screen part (30) can pass through.

[0064] The first driving motor (43) of the first driving unit (40) to be described later is fixedly installed on the first motor fixing bracket (134), and the first idle roller (41) of the first driving unit (40) can be supported and coupled to the first roller bracket (134a) so as to be rotatable in place.

[0065] The first guide block (135) can support the main part of the guide portion (60) to be described later, for example, the upper guide bar (61) in a slidable manner.

[0066] In addition, a first upper bar insertion hole (136) is formed through the first guide block (135) of a pair of first lateral support blocks (131) at the same line position, so that an upper guide bar (61) connected to the first guide block (135) can pass through the first upper bar insertion hole (136) of the first lateral support block (131) and be coupled.

[0067] Next, the second frame section (200) can be exemplified as including a second rail frame (210), a second lower frame (220), and a second upper frame (230).

[0068] The second rail frame (210) is formed to be extended in the vertical direction and may have a second rail (211) to which the right corner of the screen section (30) is connected in the inner direction facing the screen section (30).

[0069] Based on the second rail frame (210), a second upper frame (230) can be integrally connected to the upper part of the second rail frame (210), and a second lower frame (220) can be integrally connected to the lower part of the second rail frame (210).

[0070] The second lower frame (220) constitutes the lowest part of the second frame section (200) and may be formed as a long bar-shaped structure extending a certain length in the direction of the first frame section (100) facing the lower part of the second rail frame (210).

[0071] When the screen part (30) is moved to the lowest position, the lower part of the screen part (30) can be supported on the second lower frame (220).

[0072] A second lower bar insertion hole (221) can be formed through the second lower frame (220) in the left and right directions, and a key configuration of a guide portion (60) to be described later, for example, a lower guide bar (62), can be inserted and installed in the second lower bar insertion hole (221).

[0073] The second lower bar insertion hole (221) is arranged concentrically with the first lower bar insertion hole (121) described above to support the insertion of the lower guide bar (62).

[0074] The second upper frame (230) is a plate-shaped structure formed to extend a certain length in the direction of the first frame portion (100) facing parallel to the second lower frame (220) from the upper end of the second rail frame (210), and can support the second driving unit (50) to be described later.

[0075] A pair of second lateral support members (231) are formed to protrude and face each other on the left and right ends of the second upper frame (230), and a second rear support member (232) is formed at the rear end to connect the pair of second lateral support members (231), thereby forming a body structure in which the front and a portion of the upper part are opened above the second upper frame (230), and a second finishing cover (233) is detachably mounted on the open front and upper part to form a body structure having an internal space approximately above the second upper frame (230). A second driving unit (50) can be installed in the internal space of the body thus configured.

[0076] A second operating hole (240) may be continuously cut and formed in the second upper frame (230) and the second side support (231) to allow the screen portion (30) to pass through.

[0077] A second motor fixing bracket (234) and a second guide block (235) may be provided on the upper surface of the second upper frame (230), and a second roller bracket (234a) may be provided on the second rear support (232).

[0078] The second driving motor (53) of the second driving unit (50) to be described later is fixedly installed on the second motor fixing bracket (234), and the second idle roller (51) of the second driving unit (50) can be supported and coupled to the second roller bracket (234a) so as to be rotatable in place.

[0079] The second guide block (235) can support the main part of the guide portion (60) to be described later, for example, the upper guide bar (61) in a slidable manner.

[0080] In addition, a second upper bar insertion hole (236) is formed through the second guide block (235) of a pair of second lateral support blocks (231) at the same line position, so that the upper guide bar (61) connected to the second guide block (235) can pass through the second upper bar insertion hole (236) of the second lateral support block (231) and be coupled.

[0081] The detection unit (20) and the control unit have the same configuration as in the above-described embodiment, but the detection unit (20) in this embodiment is installed on the upper side of at least one of the first frame unit (100) and the second frame unit (200) so as to detect the approach of a companion animal.

[0082] The screen section (30) is connected between the first frame section (100) and the second frame section (200) so as to be able to move up and down, thereby opening and closing the passage (R).

[0083] The left part of the screen portion (30) can be inserted into the first operating hole (140), and the right part can be inserted into the second operating hole (240), and in particular, the left end can be connected to the first rail (111), and the right end can be connected to the second rail (211).

[0084] The first driving unit (40) and the second driving unit (50) are configured to reciprocate and pull the screen unit (30) up and down. The first driving unit (40) is installed on the upper part of the first frame unit (100) and is in contact with the left part of the screen unit (30) to reciprocate and pull the screen unit (30) up and down. The second driving unit (50) is installed on the upper part of the second frame unit (200) and is in contact with the right part of the screen unit (30) to reciprocate and pull the screen unit (30) up and down.

[0085] That is, the first driving unit (40) and the second driving unit (50) are installed in the first frame unit (100) and the second frame unit (200) which are spaced apart from each other, respectively, so that the left and right sides of the screen unit (30) can be individually moved and controlled, and thus, even if the area of ​​the screen unit (30) becomes relatively large, a structure is provided in which the screen unit (30) can operate up and down more stably.

[0086] First, the first driving unit (40) can be exemplified as including a first idle roller (41) that is installed so as to be rotatable in place on a first roller bracket (134a) provided on a first rear support member (132), a first driving roller (42) that is positioned a predetermined distance in front of the first idle roller (41) so that a screen portion (30) is interposed between the first idle roller (41) and the first driving roller (41), and a first driving motor (43) that is installed on the upper portion of the first upper frame (130) and is connected to the first driving roller (42) to drive the first driving roller (42) to rotate in a forward and reverse direction.

[0090] The screen portion (30) extending to the upper part of the second upper frame (230) through the second operating hole (240) can be interposed in the space between the second idle roller (51) and the second driving roller (52), and the screen portion (30) interposed in this way can move back and forth up and down in conjunction with the rotation of the second driving roller (52).

[0091] The second driving motor (53) is installed in the second motor fixing bracket (234), and the second driving roller (52) is coupled to the rotational axis of the second driving motor (53) and can rotate in the forward and reverse directions according to the driving of the second driving motor (53).

[0092] The control unit controls the first driving motor (43) and the second driving motor (53) in a synchronous direction and speed so that the screen unit (30) can move stably in the up and down direction.

[0093] Next, the guide part (60) is configured to movably connect and support the first frame part (100) and the second frame part (200) so that the gap between the first frame part (100) and the second frame part (200) can be adjusted.

[0094] More specifically, the guide portion (60) can be exemplified as including an upper guide bar (61) that is connected to the first upper bar insertion hole (136) of the first frame portion (100), the first guide block (135) and the second upper bar insertion hole (236) and the second guide block (235) of the second frame portion (200) by mutually penetrating the first frame portion (100) and the second frame portion (200) by mutually penetrating the second guide block (235), and a lower guide bar (62) that is connected to the first lower bar insertion hole (121) of the first frame portion (100) and the second lower bar insertion hole (221) of the second frame portion (200) by mutually penetrating the first frame portion (100) and ...

[0095] That is, the upper guide bar (61) penetrates the upper portions of the first frame portion (100) and the second frame portion (200) left and right to connect the upper portions of the first frame portion (100) and the second frame portion (200), and the lower guide bar (62) penetrates the lower portions of the first frame portion (100) and the second frame portion (200) left and right to connect the lower portions of the first frame portion (100) and the second frame portion (200), thereby simultaneously connecting the upper and lower portions of the first frame portion (100) and the second frame portion (200), thereby preventing the first frame portion (100) and the second frame portion (200) from tilting forward and backward.

[0096] In addition, the first frame part (100) and the second frame part (200) are guided by the upper guide bar (61) and the lower guide bar (62) to enable parallel movement left and right, and accordingly, the area of ​​the passage (R), which is the space between the first frame part (100) and the second frame part (200), can be appropriately adjusted according to the situation.

[0097] For example, if the first frame part (100) and the second frame part (200) move away from each other, the open area of ​​the passage (R) may become relatively larger, and conversely, if the first frame part (100) and the second frame part (200) move toward each other, the open area of ​​the passage (R) may become relatively smaller.

[0098] At this time, a screen section (30) cut to an appropriate size according to the open area of ​​the variable passage (R) can be used.

[0099] Meanwhile, in order to fix the first frame part (100) or the second frame part (200) to a fixed position on the upper guide bar (61), a fixing force can be applied toward the upper guide bar (61) at the points of the first guide block (135) and the second guide block (235).

[0100] To this end, a first guide hole (135d) through which an upper guide bar (61) passes is formed penetrating in the left-right direction in the first guide block (135), and a cylindrical first sleeve (135a) is formed extending along the outer longitudinal direction of the upper guide bar (61) passing through the first guide hole (135d), and the outer surface of the first sleeve (135a) has a structure in which a screw thread is formed and a first deformation-inducing hole (135b) of a certain area is cut and formed.

[0101] When the first tightening nut (135c) is screw-fastened to the first sleeve (135a) of this structure, the upper guide bar (61) passing through the inside of the first sleeve (135a) can be strongly tightened and fixed as the first sleeve (135a) is compressed based on the first deformation inducing hole (135b).

[0102] Likewise, a second guide hole (235d) through which an upper guide bar (61) passes is formed penetrating in the left-right direction in the second guide block (235), and a cylindrical second sleeve (235a) is formed extending along the outer longitudinal direction of the upper guide bar (61) passing through the second guide hole (235d), and the outer surface of the second sleeve (235a) has a structure in which a second deformation-inducing hole (235b) having a predetermined area is cut and formed.

[0103] When the second tightening nut (235c) is screw-fastened to the second sleeve (235a) of this structure, the upper guide bar (61) passing through the inside of the second sleeve (235a) can be strongly tightened and fixed as the second sleeve (235a) is compressed based on the second deformation inducing hole (235b).

[0104] Accordingly, a structure capable of limiting the left-right movement of the first frame part (100) and the second frame part (200) above the upper guide bar (61) can be provided.

[0105] The embodiments of the present invention described above are merely exemplary, and those skilled in the art will readily appreciate that various modifications and equivalent other embodiments are possible. Therefore, it will be readily understood that the present invention is not limited to the forms mentioned in the detailed description above. Accordingly, the true technical protection scope of the present invention should be defined by the technical spirit of the appended claims. Furthermore, the present invention should be understood to include all modifications, equivalents, and alternatives within the spirit and scope of the present invention as defined by the appended claims.
