Description

Technical Field

[0001] This utility model relates to the field of cabinet door lock technology, and in particular to an auxiliary door pushing device. Background Technology

[0002] For aesthetic reasons, many cabinets and drawer cabinets on the market feature concealed handles or even no handles at all (with the addition of push-button mechanisms). Users open and close the doors using either the concealed handle or the push-button mechanism (a light press opens the door, another light press closes it). If the cabinet door uses a lock without a push-button mechanism, a handle (surface or concealed) must be added to the door or drawer to open it. If a push-button mechanism is added, a problem arises where pressing the door before unlocking causes the mechanism to spring open, creating significant force on the door. Since the lock is closed, this force is applied between the latch and bolt. When attempting to unlock, this increased friction can wear down the lock or even prevent it from opening. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides an auxiliary door opening device that can automatically open cabinet doors or drawers when the cabinet lock is opened, achieving the effect of easily opening doors without handles.

[0004] This utility model is achieved using the following technical solution:

[0005] An auxiliary door pushing device includes:

[0006] A latch, used for mounting on a door and located on one side of the lock body;

[0007] The lock body includes a latch, a push-door mechanism, and a control circuit board. The latch has a locked state where it engages with the latch and an unlocked state where it disengages from the latch. The control circuit board controls the movement of the latch. The push-door mechanism has a first position and a second position and can move between the first and second positions. The push-door mechanism is electrically connected to the control circuit board. When the latch is in the unlocked state, the push-door mechanism is configured to move from the first position to the second position to push the latch out of the lock body, thus opening the door. When the latch is pressed into the lock body, the latch pushes the push-door mechanism from the second position to the first position, allowing the latch to move towards the latch, so that the latch engages with the inserted latch, thus locking the door.

[0008] Furthermore, the latch is configured to move linearly along a first direction to engage with or disengage from the latch, and the door pushing mechanism is configured to contact the latch and move linearly along a second direction, wherein the first direction is perpendicular to the second direction.

[0009] Furthermore, the direction of movement of the latch is consistent with the direction of movement of the door pushing mechanism.

[0010] Furthermore, it also includes a detection unit electrically connected to the control circuit board. The detection unit is used to generate a signal according to the movement direction of the door pushing mechanism. When the detection unit detects that the door pushing mechanism moves from the first position to the second position, the detection unit sends a push signal to the control circuit board. The control circuit board outputs an unlocked signal according to the received push signal. When the detection unit detects that the door pushing mechanism moves from the second position to the first position, the detection unit sends a push signal to the control circuit board. The control circuit board outputs a locked signal according to the received push signal.

[0011] Furthermore, it also includes a prompting unit electrically connected to the control circuit board. When the time for which the control circuit board outputs the unlocked signal is greater than a preset time value, the control circuit board sends an alarm signal to the prompting unit. The prompting unit is used to provide an alarm prompt based on the received alarm signal.

[0012] Furthermore, the alarm prompt is an audible prompt and / or a visual prompt.

[0013] Furthermore, the prompting unit includes a buzzer and / or an indicator light.

[0014] Furthermore, the control circuit board is equipped with a wireless communication module, which is connected to the terminal device. The wireless communication module is used to receive alarm information sent by the control circuit board and send the alarm information to the terminal device through a wireless network.

[0015] Furthermore, the door pushing mechanism includes a door pushing component and a driving component connected to the door pushing component. The driving component is used to drive the door pushing component to move linearly between a first position and a second position. The driving component is electrically connected to the control circuit board.

[0016] Furthermore, the driving component is a miniature motor or an electric cylinder.

[0017] Compared with the prior art, the beneficial effects of this utility model include at least the following:

[0018] This utility model adds a push-door mechanism and a control circuit board to the lock body, so that the cabinet door or drawer automatically pops open after the lock body is unlocked, achieving the effect of easy opening without a handle, maintaining the overall aesthetics of the cabinet door or drawer, and improving the user experience without the need to press the pop-up button.

[0022] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0023] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0024] like Figure 1 and Figure 2 As shown, this utility model provides an auxiliary door pushing device, comprising:

[0025] The latch 1 is used to install on the door and is located on one side of the lock body 2;

[0026] The lock body 2 has a latch 21, and the lock body 2 also includes a push-door mechanism 22 and a control circuit board 23. The latch 21 has a locked state that engages with the latch 1 and an unlocked state that disengages from the latch 1. The control circuit board 23 is used to control the movement of the latch 21. The push-door mechanism 22 has a first position and a second position and can move between the first position and the second position. The push-door mechanism 22 is electrically connected to the control circuit board 23. When the latch 21 is in the unlocked state, the push-door mechanism 22 is configured to move from the first position to the second position to push the latch 1 out of the lock body 2, thereby opening the door. When the latch 1 is pressed into the lock body 2, the latch 1 pushes the push-door mechanism 22 from the second position to the first position, allowing the latch 21 to move towards the latch 1, so that the latch 21 engages with the inserted latch 1, thereby locking the door.

[0027] In this embodiment, the latch 1 is installed on the cabinet door or drawer panel, and the lock body 2 is installed on the other side of the cabinet door or drawer. The lock body 2 can be unlocked by a lock pick. When the cabinet door is closed (the latch 21 is locked), the user unlocks it with the lock pick. The control circuit board 23 receives the unlocking signal and controls the latch 21 to move away from the latch 1 (the latch 21 disengages from the latch 1), releasing the latch 21 from its locked state. Then, the control circuit board 23 activates the door pushing mechanism 22, which moves from the first position to the second position. The door pushing mechanism 22 pushes the latch 1 outward, realizing the function of automatically opening the cabinet door after unlocking. When the user closes the cabinet door, the latch 1 presses into the lock body 2, and the latch 1 pushes the door pushing mechanism 22 from the second position to the first position, allowing the latch 21 to move closer to the latch 1. In this way, the latch 21 and the latch 1 are engaged, realizing the locking of the door.

[0028] This utility model adds a push-door mechanism 22 and a control circuit board 23 to the lock body 2, so that the cabinet door or drawer will automatically pop open after the lock body 2 is unlocked, achieving the effect of easy opening without a handle, maintaining the overall aesthetics of the cabinet door or drawer, and improving the user experience without the need to press the pop-up button.

[0029] In a preferred embodiment, the latch 21 is configured to move linearly along a first direction to engage with or disengage from the latch 1, and the door pushing mechanism 22 is configured to contact the latch 21 and move linearly along a second direction, wherein the first direction is perpendicular to the second direction.

[0030] In this embodiment, Figure 1 Y represents the first direction. Figure 1X represents the second direction. When the control circuit board 23 controls the latch 21 to move downward in the first direction, the latch 21 moves away from the pusher, and the push mechanism 22 pushes in a direction perpendicular to the latch 21, thereby pushing the latch 1 and popping the cabinet door outward. The vertical movement design of the latch 21 and the push mechanism 22 enables the two actions of unlocking and pushing the door to work together in a compact space, which not only ensures the locking function, but also realizes automatic door pushing, and simplifies the control logic.

[0031] In a preferred embodiment, the movement direction of the latch 1 is consistent with the movement direction of the door-pushing mechanism 22. In this embodiment, the movement directions of the latch 1 and the door-pushing mechanism 22 are consistent, which can ensure that the latch 1 can accurately push the door-pushing mechanism 22 inward to realize the latch 1 and the latch tongue 21 engaging. At the same time, the door-pushing mechanism 22 can accurately push the latch 1 to realize the automatic opening of the door.

[0032] In a preferred embodiment, a detection unit 24 electrically connected to the control circuit board 23 is further included. The detection unit 24 is used to generate a signal according to the movement direction of the door pushing mechanism 22. When the detection unit 24 detects that the door pushing mechanism 22 moves from the first position to the second position, the detection unit 24 sends a push signal to the control circuit board 23. The control circuit board 23 outputs an unlocked signal according to the received push signal. When the detection unit 24 detects that the door pushing mechanism 22 moves from the second position to the first position, the detection unit 24 sends a push signal to the control circuit board 23. The control circuit board 23 outputs an locked signal according to the received push signal.

[0033] In this embodiment, the movement direction of the door-pushing mechanism 22 is monitored by the detection unit 24. When the control circuit board 23 receives the unlocking signal, it starts the door-pushing mechanism 22, which moves from the first position to the second position. The detection unit 24 sends a push signal to the control circuit board 23, and the control circuit board 23 outputs an unlocked signal based on the received push signal. When the detection unit 24 detects that the door-pushing mechanism 22 has moved from the second position to the first position, it sends a push signal to the control circuit board 23, and the control circuit board 23 outputs a locked signal based on the received push signal. This real-time status monitoring ensures that the system always knows the current status of the cabinet lock, providing accurate status information to the control circuit board 23, enabling the system to react in a timely manner. This makes the entire system more reliable and intelligent, improving the convenience and security of user operation.

[0034] In a preferred embodiment, a prompting unit 25 electrically connected to the control circuit board 23 is also included. When the time for the control circuit board 23 to output the unlocked signal is greater than a preset time value, the control circuit board 23 sends an alarm signal to the prompting unit 25. The prompting unit 25 is used to provide an alarm prompt based on the received alarm signal.

[0035] In this embodiment, if the lock is not closed for a certain period of time after being unlocked, the control circuit will output a signal indicating that the lock has not been closed for an extended period. If the time for which the control circuit board 23 outputs the unlocked signal exceeds a preset time value, the control circuit board 23 will send an alarm signal to the prompting unit 25. The prompting unit 25 will then issue an alarm notification based on the received alarm signal. This effectively reminds the user to close the cabinet door in a timely manner, preventing potential safety issues or loss of contents due to prolonged openness. The prompting unit 25 increases the intelligence of the cabinet lock, enabling it to remind the user in specific situations (such as prolonged unlocking), preventing safety hazards caused by negligence, and improving the overall system security and user-friendliness.

[0036] In a preferred embodiment, the alarm prompt is an audible prompt and / or a visual prompt. In this embodiment, an audible prompt refers to using sound, such as a beeping sound or voice prompt; a visual prompt refers to using flashing lights, such as a flashing red warning light; different methods are used to remind the user and meet different user needs.

[0037] In a preferred embodiment, the prompting unit 25 includes a buzzer and / or an indicator light.

[0038] In a preferred embodiment, the control circuit board 23 is equipped with a wireless communication module. This module is connected to a terminal device and receives alarm information sent by the control circuit board 23, then transmits the alarm information to the terminal device via a wireless network. This wireless communication module design allows users to promptly obtain alarm information through the terminal device, further improving the overall intelligence level and user experience of the locker system.

[0039] In a preferred embodiment, the door pushing mechanism 22 includes a door pushing component and a driving component connected to the door pushing component. The driving component is used to drive the door pushing component to move linearly between a first position and a second position. The driving component is electrically connected to the control circuit board 23.

[0040] In this embodiment, the linear motion of the door pusher is driven by a drive component, ensuring that the door pusher can move precisely between the first and second positions. The control circuit board 23 sends electrical signals to the drive component to control its start, stop, direction of movement, and speed, thereby achieving precise control of the door pusher's movement.

[0041] In a preferred embodiment, the driving component is a micro motor or an electric cylinder.
