Description

Technical Field

[0001] This utility model relates to the field of locks, and in particular to a wirelessly powered smart cabinet lock. Background Technology

[0002] Existing smart cabinet locks mainly consist of two parts: a first lock seat and a second lock seat. The first lock seat is located on the inside of the cabinet door, while the wiring of the second lock seat passes through the door and connects to the display device and unlocking device on the outside. The first lock seat is located on the inside of the cabinet and is directly connected to the mains power. During use, because the door needs to be opened, the wiring cannot be directly connected to the first lock seat. Therefore, a battery is often installed in the first lock seat to power the electronic equipment. However, in actual use, the battery may run out of power, requiring regular battery replacement; otherwise, the door may become unusable. Therefore, there is a need for a wirelessly powered smart cabinet lock that incorporates wireless power supply modules in both the first and second lock seats. This would allow the second lock seat to power the first lock seat during unlocking, thus reducing battery costs while improving security. Utility Model Content

[0003] The main purpose of this utility model is to provide a wireless power supply smart cabinet lock that can provide power to the first lock seat through the second lock seat and unlock the cabinet by setting wireless power supply modules in the second lock seat and the first lock seat respectively, thereby reducing battery costs and improving security.

[0004] This utility model proposes a wirelessly powered smart cabinet lock, including a second lock seat and a first lock seat. The second lock seat is installed on the cabinet door, and the first lock seat is installed inside the cabinet.

[0032] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0033] Reference Figures 1 to 5 An embodiment of the wirelessly powered smart cabinet lock of this utility model is proposed:

[0034] A wirelessly powered smart cabinet lock includes a second lock seat 2 and a first lock seat 1. The second lock seat 2 is installed inside the cabinet, and the first lock seat 1 is installed on the cabinet door.

[0035] The first lock base 1 includes a first lock base housing, a power supply module receiving device 13, a supercapacitor 15, a first lock base circuit board 14, a first lock body 16, and a first lock body driving device 17. The first lock base housing includes a first lock base housing body 11 and a side connecting housing 12, which are connected by a snap-fit ​​method. In addition, the first lock base housing body 11 and the side connecting housing 12 are respectively fixedly connected to the cabinet door by screws.

[0036] The side connecting housing 12 is provided with a side connecting housing connecting groove. A first connecting hole of the connecting groove is provided on the side of the side connecting housing facing the first lock seat housing body, and a second connecting hole of the connecting groove is provided on the side of the side connecting housing facing the second lock seat. The angle between the first connecting hole and the second connecting hole of the connecting groove is a right angle.

[0037] The power supply module receiving device 13 includes a receiving circuit board 131 and a receiving coil 132, both of which are housed within the side connecting housing 12. The first lock seat circuit board 14, the first lock body 16, the supercapacitor 15, and the first lock body driving device 17 are housed within the first lock seat housing body 11. The first lock body driving device 17 includes a first latch driving device and a second latch driving device. The first lock body 16 is provided with a first lock body actuating block 161. The first latch driving device and the second latch driving device can respectively drive the first lock body 16 forward or backward via the first lock body actuating block 161. The first latch driving device and the second latch driving device are connected to the first lock seat circuit board 14. The supercapacitor 15, the first latch driving device, the second latch driving device, and the power supply module receiving device 13 are electrically connected to the first lock seat circuit board 14.

[0038] The second lock seat 2 includes a second lock seat housing 21, a touch switch 27, a light source, a second lock seat circuit board 23, a pop-out contact 25, a pop-out spring 26, and a power supply module transmitter 24. The power supply module transmitter 24 includes a transmitting coil. The second lock seat circuit board 23, the touch switch 27, the pop-out contact 25, the pop-out spring 26, and the transmitting coil are all disposed within the second lock seat housing 21. The second lock seat circuit board 23 is electrically connected to the touch switch 27 and the transmitting coil. The second lock seat housing 21 is provided with an outer latch 22 fixedly connected to the second lock seat housing 21. The outer latch 22 is provided with an outer latch connection hole 221. The second lock seat housing 21 is provided with a pop-out groove. The rear side of the pop-out contact 25 is fixedly connected to the pop-out spring 26, and the pop-out contact 25 and the pop-out spring 26 are disposed within the pop-out groove. After unlocking, the first lock seat 1 can be pushed away from the second lock seat 2 by the pop-out contact 25, thereby opening the door. The touch switch 27 is provided with a connecting handle 271 at its bottom. A touch switch 27 is disposed on the side of the pop-out contact 25. A contact protrusion adapted to the connecting hand 271 is disposed on the side of the pop-out contact 25 adjacent to the touch switch 27. When the pop-out contact 25 is confined within the pop-out groove, the contact protrusion does not contact the connecting hand 271, and the light-emitting lamp does not emit light. After the pop-out contact 25 is released from its confined position, the contact protrusion contacts the connecting hand 271, causing the light-emitting lamp to emit light.

[0039] When the door is closed, the outer latch 22 is inserted into the side connecting housing connecting groove through the second connecting hole of the connecting groove. At this time, the pop-out contact 25 is pressed into the pop-out groove, and the pop-out contact 25 does not contact the connecting hand 271, so the light-emitting lamp does not emit light. The second lock seat circuit board 23 drives the transmitting coil to work and emit an electrical signal. The electrical signal is input to the first lock seat circuit board 14 through the receiving coil 132. At the same time, the electrical signal can also supply power to the supercapacitor 15. After receiving the electrical signal, the first lock seat circuit board 14 controls the first lock body driving device 17 to work. The first lock body driving device 17 drives the first lock body 16 to move. The first lock body 16 is inserted into the side connecting housing connecting groove through the first connecting hole of the connecting groove and into the outer latch connecting hole, thus completing the locking of the door.

[0040] When the door is opened, the second lock seat circuit board 23 drives the transmitting coil to emit an electrical signal. This signal is input to the first lock seat circuit board 14 via the receiving coil 25, and simultaneously powers the supercapacitor 15. Upon receiving the signal, the first lock seat circuit board 14 controls the first lock body driving device 17 to operate. The first lock body driving device 17 drives the first lock body 16 to move, completing the door opening. The pop-out contact 25 pushes the first lock seat 1 to move, disengaging it from the first lock seat 2. At this point, the contact protrusion contacts the connecting hand 271, causing the light-emitting lamp to illuminate.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
