Description

Technical Field

[0001] This utility model relates to the field of smart lock technology for switch cabinets, specifically a smart lock. Background Technology

[0002] A smart lock for switchgear is an intelligent locking system applied to power switchgear. It achieves secure control of the cabinet through electronic technology and network communication capabilities. It adopts multiple authentication methods such as password, fingerprint, and IC card to replace the traditional mechanical key. It has a built-in motor to drive the lock tongue and controls the lock body opening and closing through electronic signals. Conventional smart locks for switchgear mainly use robots or chips for identification and operation.

[0003] However, in actual use, the smart locks of existing switchgear are mostly electronic in structure. During operation, they can only be identified by the equipped NFC chip, electronic password, etc. Once the smart lock is damaged due to power supply or internal electrical components, it is difficult to open it in a short time, which seriously affects the maintenance and use of the switchgear.

[0004] Therefore, a smart lock was proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a smart lock to solve the problem that existing smart locks for switch cabinets, due to their electronic structure, can only be identified through NFC chips, electronic passwords, etc. during operation. Once the smart lock is damaged due to power supply or internal electrical components, it is difficult to open it in a short time, which seriously affects the maintenance and use of the switch cabinet.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a smart lock, including a smart lock body and a mounting panel hinged to the top rear of the smart lock body, and the mounting panel is fixedly mounted to the front of the cabinet panel by bolts.

[0007] The cabinet panel has an operation slot at the bottom front, and an operation switch is installed inside the operation slot.

[0008] The smart lock body is provided with a first unlocking mechanism inside, and the unlocking mechanism includes a lead screw sleeve, which slides through the bottom of the smart lock body to block the operation switch inside the operation slot.

[0009] A second unlocking mechanism is provided on the right side of the mounting panel, and the second unlocking mechanism includes a mechanical external lock, and includes a main lock ring and a secondary lock ring.

[0010] Preferably, the first unlocking mechanism includes an identification module, which is fixedly installed on the front top of the smart lock body. An induction coil is fixedly installed in the identification module inside the smart lock body. The identification module and the induction coil are used to identify the robot's NFC chip.

[0011] Preferably, the first unlocking mechanism includes a positioning bracket, which is fixedly installed at the center of the lower part of the smart lock body. A servo motor is fixedly installed on the upper left side of the positioning bracket, and an active gear is fixedly installed at the top of the output shaft of the servo motor.

[0012] Preferably, the first unlocking mechanism includes a driven gear, which is rotatably disposed at the top right end of the positioning bracket, and is meshed with the driving gear. Furthermore, a drive screw is rotatably disposed on the right bearing inside the positioning bracket.

[0013] Preferably, the upper end of the drive screw included in the first unlocking mechanism is fixedly connected to the driven gear, and the lower end of the drive screw is threadedly connected to the inside of the screw sleeve, and a guide groove is provided at the rear of the screw sleeve.

[0014] Preferably, the first unlocking mechanism includes a guide protrusion fixedly installed at the rear center position inside the positioning bracket, and the guide protrusion is slidably disposed in the guide groove behind the lead screw sleeve, and a limit protrusion is fixedly installed on the top of the front side of the lead screw sleeve.

[0015] Preferably, the first unlocking mechanism includes a micro switch plate fixedly installed inside the front of the positioning bracket, and the micro switch plate achieves sliding contact with the limiting protrusion on the front of the lead screw sleeve through the micro switches on the upper and lower sides, and the limiting protrusion limits the lead screw sleeve by contacting the micro switch of the micro switch plate.

[0016] Preferably, the second unlocking mechanism includes a main locking ring fixedly installed on the upper right side of the mounting panel, and a secondary locking ring included in the second unlocking mechanism is fixedly installed on the upper right side of the smart lock body. The main locking ring and the secondary locking ring are arranged in a concentric vertical distribution, and the main locking ring and the secondary locking ring are connected by a mechanical external lock to lock the smart lock body and the mounting panel.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This smart lock, through the matching of the robot's NFC chip with the smart lock body, causes the lead screw sleeve covering the front of the operating switch to rise, so as to unlock the operating switch. At the same time, the mechanical outer lock locks the smart lock body and the mounting panel. After unlocking, the operating switch can be manually used by flipping the smart lock body. The specific details are as follows:

[0018] 1. The lead screw sleeve penetrating the bottom of the smart lock body shields the operation slot and operation switch, ensuring that the operation switch is not accidentally touched by external force under normal conditions. The robot matches the identification module on the front of the smart lock body through the NFC chip, drives the servo motor and the active gear to drive the driven gear to rotate, and the drive lead screw fixedly installed on the bottom of the driven gear rotates inside the positioning bracket.

[0019] Furthermore, the lead screw sleeve is slidably limited by the guide groove and the guide protrusion, so that the rotating drive screw drives the threaded lead screw sleeve to move upward, so that the bottom end of the lead screw sleeve is no longer blocked from the operating slot, so that the operating switch can be operated to open and close.

[0020] 2. During the lifting and lowering process, the lead screw sleeve drives the limit protrusion to move synchronously. The limit protrusion contacts the microswitches on the upper and lower sides of the microswitch plate. After the microswitch on either side contacts the limit protrusion, it controls the servo motor to stop working, so that the lead screw sleeve stops lifting and lowering, so as to achieve the stop of the lead screw sleeve and avoid excessive movement and misalignment.

[0021] 3. The secondary locking ring and the main locking ring are locked by a mechanical external lock to ensure that the smart lock body cannot be flipped. After the mechanical external lock is opened, the smart lock body is flipped upward, which drives the bottom screw sleeve to flip synchronously, so that the screw sleeve no longer blocks the operating slot and operating switch, so that manual operation can be performed.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-7 The present invention provides the following technical solution:

[0032] Example 1: To address the problems existing in the use of current smart locks for switch cabinets, this example discloses the following technical solution: a smart lock, comprising a smart lock body 1 and a mounting panel 2 hinged to the top rear of the smart lock body 1, and the mounting panel 2 is fixedly mounted to the front of the cabinet panel 3 by bolts; wherein, an operation slot 4 is provided at the bottom of the front of the cabinet panel 3, and an operation switch 5 is provided inside the operation slot 4; a first unlocking mechanism is provided inside the smart lock body 1, and the unlocking mechanism includes a lead screw sleeve 6, which slides through the bottom of the smart lock body 1 to block the operation switch 5 inside the operation slot 4; the first unlocking mechanism includes an identification module 10, and the identification module 10 is fixedly mounted on the top of the front of the smart lock body 1, and an induction coil 11 is fixedly provided in the identification module 10 inside the smart lock body 1, and the identification module 10 and the induction coil 11 are used to identify the NFC chip of a robot.

[0033] like Figures 1-3 As shown, the smart lock body 1 is fixed by a hinged mounting panel 2, and the mounting panel 2 can be installed in different cabinet panel 3 positions as needed. The threaded sleeve 6 that penetrates the bottom surface of the smart lock body 1 covers the front of the operation slot 4 opened below the cabinet panel 3, so as to block the operation switch 5 set inside the operation slot 4 and prevent the operation switch 5 from being accidentally touched due to external force.

[0034] The first unlocking mechanism includes a positioning bracket 12, which is fixedly installed at the center of the lower part of the smart lock body 1. A servo motor 13 is fixedly installed on the upper left side of the positioning bracket 12, and a drive gear 14 is fixedly installed at the top of the output shaft of the servo motor 13. The first unlocking mechanism includes a driven gear 15, which is rotatably disposed on the top right end of the positioning bracket 12. The driven gear 15 is meshed with the drive gear 14. A drive screw 16 is rotatably disposed on the right bearing inside the positioning bracket 12. The upper end of the drive screw 16 is fixedly connected to the driven gear 15, and the lower end of the drive screw 16 is threadedly connected to the inside of the screw sleeve 6. A guide groove 17 is provided at the rear of the screw sleeve 6.

[0035] The first unlocking mechanism includes a guide protrusion 18 fixedly installed at the rear center position inside the positioning bracket 12, and the guide protrusion 18 is slidably disposed in the guide groove 17 behind the lead screw sleeve 6, and a limiting protrusion 19 is fixedly installed at the top of the front of the lead screw sleeve 6; the first unlocking mechanism includes a micro switch plate 20 fixedly installed inside the front of the positioning bracket 12, and the micro switch plate 20 achieves sliding contact with the limiting protrusion 19 on the front of the lead screw sleeve 6 through the micro switches on the upper and lower sides, and the limiting protrusion 19 limits the lead screw sleeve 6 by contacting the micro switch of the micro switch plate 20.

[0036] like Figures 4-7 As shown, the robot matches the identification module 10 and the induction coil 11 on the front of the smart lock body 1 with the NFC chip, so that the identification module 10 controls the servo motor 13 above the positioning bracket 12 to work, so that the active gear 14 at the top of its output shaft drives the meshing driven gear 15 to rotate, and the drive screw 16 fixedly installed on the bottom of the driven gear 15 rotates inside the positioning bracket 12.

[0037] Furthermore, the screw sleeve 6, which is threadedly connected to the drive screw 16, is slidably connected to the guide protrusion 18 through the guide groove 17 opened at the rear, so that the rotating drive screw 16 drives the threaded screw sleeve 6 to move upward, so that the bottom end of the screw sleeve 6 is no longer blocked from the operating slot 4, so that the operating switch 5 can be operated to open and close.

[0038] like Figure 7 As shown, the lead screw sleeve 6 inside the smart lock body 1 drives the front limiting protrusion 19 synchronously during the upward process, so that the limiting protrusion 19 slides between the micro switches on the upper and lower sides of the micro switch plate 20. When the limiting protrusion 19 contacts the micro switch on either side, it drives the lead screw sleeve 6 to stop rising and falling, so as to achieve the stop of the lead screw sleeve 6 and avoid excessive movement and misalignment.

[0039] Example 2: To address the problems existing in the use of existing smart locks for switch cabinets, this example discloses the following technical solution: A second unlocking mechanism is provided on the right side of the mounting panel 2, and the second unlocking mechanism includes a mechanical external lock 7, a main lock ring 8, and a secondary lock ring 9; the main lock ring 8 of the second unlocking mechanism is fixedly installed on the upper right side of the mounting panel 2, and the secondary lock ring 9 of the second unlocking mechanism is fixedly installed on the upper right side of the smart lock body 1, and the main lock ring 8 and the secondary lock ring 9 are arranged concentrically and vertically, and are connected by the mechanical external lock 7 to lock the smart lock body 1 to the mounting panel 2.

[0040] like Figures 1-3 As shown, the smart lock body 1 corresponds to the main lock ring 8 on the right side of the mounting panel 2 via the auxiliary lock ring 9 on the right side, so that it can be locked through by the mechanical external lock 7, so that the smart lock body 1 and the mounting panel 2 cannot be flipped, ensuring that the screw sleeve 6 can be in the low position to meet the requirements of the operation switch 5.

[0041] Furthermore, when manual operation of the operating switch 5 is required, it is opened by a mechanical key that matches the mechanical outer lock 7, so that after the mechanical outer lock 7 is removed, it no longer locks the main lock ring 8 and the secondary lock ring 9. Then, the smart lock body 1 is flipped upward, which drives the bottom screw sleeve 6 to flip synchronously, so that the screw sleeve 6 no longer blocks the operating slot 4 and the operating switch 5, so that manual operation can be performed.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
