DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-9 In an embodiment of the present invention, a handle-type finger vein smart lock includes a mechanical unlocking structure, an electronic lock control component and a finger vein component; the mechanical unlocking structure, the electronic lock control component and the finger vein component are all configured in the smart lock;

[0034] The electronic lock control component is used to realize the locking and unlocking control of the smart lock;

[0035] The finger vein component is used to identify and process finger vein information, and when the finger vein verification is passed, the motor is driven to unlock;

[0036] The mechanical unlocking structure is used to realize locking and unlocking control of the smart lock in the electronic lock control component.

[0037] The finger vein assembly includes a finger vein main board 1, a reflector 3, a vibration motor 4, a first touch sensing device 6, a first infrared filter 7, a second infrared filter 8 and an infrared lamp 9;

[0038] The finger vein main board 1 integrates an algorithm MCU, an external storage chip, a motor drive chip, and a touch sensing chip. The external storage chip, the motor drive chip, and the touch sensing chip are electrically connected to the finger vein main board 1. The finger vein main board 1 is electrically connected to the first touch sensing device 6 via an FPC connecting line, and the vibration motor 4 is connected to the first touch sensing device 6 via a wiring terminal.

[0039] The mechanical lock mechanism includes a lock core bevel gear 31, a custom rod bevel gear 32, a motor bevel gear 33, a custom rod 34, a spring 35, a lock core 36 and a reduction motor 37;

[0040] The custom rod 34 is arranged in the handle square hole of the lock body, and the end portion is arranged in the handle square hole, and the bottom portion is arranged outside the handle square hole. The part of the custom rod 34 arranged outside the handle square hole and the locking position of the door body realize the unlocking and locking control of the door lock;

[0041] The custom rod bevel gear 32 is arranged at the end of the custom rod 34, the top of the lock core 36 is fixedly connected to the lock core bevel gear 31, the top of the lock core bevel gear 31 is provided with a useful spring 35, and the top of the reduction motor 37 is fixedly connected to the motor bevel gear 33. The custom rod bevel gear 32 is meshed with the motor bevel gear 33 under normal conditions. In normal conditions, due to the thrust of the spring 35, the lock core bevel gear 31 is pushed downward and does not mesh with the custom rod bevel gear 32. When the mechanical key is needed to open the door, the mechanical key needs to be inserted, and the key is pushed inward and turned at the same time. At this time, the lock core bevel gear 31 will mesh with the custom rod 34 gear, and rotating the custom rod 34 will drive the lock tongue of the lock body to retract.

[0042] The electronic lock control assembly includes a first connector 22, a lock control mainboard 23, a digital touch panel 24, a second connector 25, a USB socket 28, a first front and rear docking line 29, an anti-disassembly button 27 and a speaker unit 26;

[0043] The anti-disassembly button 27, the first front-to-back docking line 29, the USB socket 28, the speaker unit 26, and the digital touch panel 24 are all electrically connected to the lock control mainboard 23 through the first connector 22 and the second connector 25;

[0044] The anti-disassembly button 27 , the front and rear docking wires, the USB socket 28 , the speaker unit 26 , and the digital touch panel 24 are all electrically connected to the lock control mainboard 23 via the first connector 22 and the second connector 25 .

[0045] The finger vein assembly includes a camera module and a camera module fixing frame 2, the camera module is fixed on the camera module fixing frame 2, and the vibration motor 4 is also installed on the camera module fixing frame 2 and connected to the first touch sensing device 6 through a wiring terminal.

[0046] The electronic lock control component further includes a touch indicator light 38 , and the touch indicator light 38 is electrically connected to the venous mainboard 1 .

[0047] Among them, the handle on the indoor side has a built-in door opening knob 11, a first function button 12, a second function button 13, a third touch sensing device 14, a lock control PCBA tail plate 15, a lithium battery module 16, a second front and rear docking line 17, a toggle piece 18, a toggle reset switch 19, a second touch sensing device 20 and a third connector 21 are all built into the same indoor handle, the second front and rear docking line 17 is connected to the first front and rear docking line 29, and the motor stall detection component is composed of a toggle piece 18 and a toggle reset switch 19.

[0048] When the electronic system is used to unlock the door outdoors, the indoor door opening knob 11 starts to rotate synchronously, and the door opening knob 11 drives the toggle member 18 to rotate. When it rotates to a certain angle, the toggle reset switch 19 is toggled to one side, and the toggle reset switch 19 sends a digital signal to the main control MCU on the lock control motherboard 23 of the front panel, and the electronic system controls the reduction motor 37 to stop rotating. At this time, the door opening action is completed, and the door can be pushed or pulled. When the door is opened directly using the door opening knob 11 on the indoor side, since the reduction motor 37 on the front panel is not powered on, the door opening action can be completed very smoothly (the mechanical lock core bevel gear 31 is not engaged with the custom rod bevel gear 32, so when the door opening knob 11 is turned, the mechanical lock core bevel gear 31 will not be driven to rotate. At the same time, the indoor side also supports the electronic start mode. By touching the third touch sensing device 14 and the second touch sensing device 20 with a finger at the same time, a digital signal can be sent to the main control MCU on the lock control mainboard 23 on the front panel. At this time, the electronic system controls the reduction motor 37 to rotate to achieve the retraction of the lock tongue. When the toggle reset switch 19 is toggled to one side by the toggle member 18, the main control MCU stops the reduction motor 37 from rotating, and the lock tongue is completely retracted. The door can be opened by pushing or pulling the door. The first function button 12, the second function button 13, the second touch sensing device 20, the toggle reset switch 19, the lithium battery module 16, and the second front and rear docking line 17 are integrated into the lock control tail plate, and the touch device is connected to the lock control tail plate through the third connector 21.

[0049] The finger vein mainboard 1 is connected to the first touch sensing device 6 through a connecting line, and the finger vein mainboard 1 is also connected to the camera module through an FPC connector. The camera module is fixed on the camera module fixing frame 2, and the vibration motor 4 is also installed on the camera module fixing frame 2, and connected to the first touch sensing device 6 through a wiring terminal. It mainly plays a function of finger vein recognition verification. When the verification is passed, the motor is directly driven to open the door. Since the lock core bevel gear 31 is pushed outward by the spring 35, the lock core bevel gear 31 is not engaged with the custom rod bevel gear 32. Therefore, when the motor rotates, it will not synchronously drive the lock core bevel gear 31 to rotate;

[0050] Among them, the part of the custom rod 34 inserted outside the square hole of the lock body handle is a cylinder, which effectively solves the problem of driving the square rod to unlock after the prying piece is inserted into the lock panel from the outside. The part inserted into the lock body handle hole is a diagonally opposite right angle. IV The custom rod 34 is a stainless steel precision casting with excellent torsional strength. The reduction motor 37 is connected to the finger vein main board 1 through the limit terminal. The mechanical unlocking part structure mainly plays a mechanical emergency unlocking and motor transmission unlocking function. Normally, due to the thrust of the spring 35, the lock core bevel gear 31 is pushed outward and does not mesh with the custom rod bevel gear 32. When the mechanical key is needed to open the door, it is necessary to insert the mechanical key, push the key inward and turn the key at the same time. At this time, the lock core bevel gear 31 will mesh with the custom rod 34 gear. When rotating, the custom rod 34 drives the lock tongue of the lock body to retract. Since the electronic system is in sleep mode at this time and the motor is not powered, the motor can also be rotated synchronously normally;

[0051] The electronic lock control component mainly plays the application layer functions of adding digital password to open the door, magnetic card to open the door, Bluetooth key to open the door, network alarm, network information notification, etc. In actual application, it can be added according to actual needs.
