[0027] The utility model will be further described below in combination with the drawings and embodiments.

[0028] It should be noted that the following detailed description is all exemplary, and aims at providing further description of the present application. Unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as that generally understood by the ordinary skilled in the art to which the present application belongs.

[0029] It is to be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments consistent with the present application; as used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise; it will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, steps, operations, elements, components, and / or groups thereof, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

[0030] A waterproof intelligent lock structure, referring to Figures 1-13 , comprising a front panel, a rear panel and a dual-core electronic control system, a motor transmission box is arranged in the rear panel; the dual-core electronic control system comprises a front panel main control system and a rear panel slave control system; the front panel main control system is used for human-computer interaction control and information storage; the rear panel slave control system is used for controlling opening or closing of the lock and communication of the networking module.

[0031] Specifically: 1. Overall appearance and structural design

[0032] 1.1 Appearance and structural design

[0033] (1) The lock is made of pure copper and is integrally formed by hot stamping process. The overall structure of the front panel and the rear panel is as shown in Figure 1 , 2

[0034] The full-automatic intelligent lock is manufactured by advanced technology and adheres to the belief of making high-quality copper locks. Each product is made like an artwork. The shell, panel and some main manual parts (such as handle, clutch knob and anti-lock knob) of the lock are made of pure copper and are integrally formed by hot stamping process. Hot stamping process is also called "red stamping" in the industry and is an advanced professional process developed on the basis of modern precision forging and hot extrusion.

[0035] In order to improve the mechanical strength, two methods are generally used, one is to change the material of the parts, and the other is to change the processing method. Hot stamping process is one of the effective methods to improve the mechanical properties of parts by changing the processing method. Hot stamping process, like precision forging, heats the metal blank and shapes it in the mold, but hot stamping is generally one-time forming except for large hot stamping parts, while precision forging is generally several times of pressure forming.

[0036] ​Compared with hot extrusion, the metal blank also needs to be heated, and the structure of the hot stamping die is more complex than that of the hot extrusion die. The structural feature is that the stamping mode is organically combined with the forming mode of the cavity die. It can not only extrude the cavity type extrusion die on the press, but also can perform multi-directional demolding action at one time. Under the condition of sufficient pressure, it forces the metal material to flow through the complex cavity in the die, and extrudes the complex parts with the shape of the cavity die (injection mold). Therefore, hot stamping process is a deeper and broader development of precision forging and hot extrusion process.

[0037] Advantages of hot stamping process:

[0038] a) Hot stamping process is a less cutting machining process, the surface roughness is close to the die part size precision, the size precision can reach 6-7 level, so the mechanical cutting amount is very small;

[0039] b) The flash thickness of general small hot stamping die is about 0.5mm, while the flash thickness of forged die parts is generally more than 2mm, so the material utilization rate is much higher than that of forging;

[0040] c) The mechanical properties of hot stamped parts are good, because after hot stamping, the metal blank is heated, extruded and cooled, the metal structure changes, the defects caused by casting or drawing are eliminated, and the mechanical properties of hot stamped parts are improved;

[0041] d) Hot stamping process has been widely used in daily hardware industry production, and has replaced many products produced by die casting or casting in the past.

[0042] The hot stamping process diagram is shown in Figure 3 .

[0043] The shell is integrally formed by hot stamping process, so it has better mechanical properties. The lock shell has sufficient mechanical strength and rigidity, and can withstand 8000N pressure without permanent deformation and damage.

[0044] The manual part using hot stamping process also has high strength. When a static tension of 980N and a torque of 11.8N²m are applied to the manual part on the protection surface after locking, the lock will not open, and the manual part will not be deformed or damaged.

[0045] The shell uses copper material, which has better processing characteristics, can make various processing sizes more accurate, and is more conducive to the assembly of the whole electronic lock. Therefore, the control mechanism of our electronic lock is flexible and has no jamming phenomenon, and the manual part feels good and moves freely.

[0046] After strict electroplating process, our products have more beautiful appearance and more diversified colors. The shell surface will not be deformed, cracked, faded, and have no burrs, sand holes, bubbles, corrosion, scratches, coating peeling and other process defects.

[0047] 1.2 Waterproof structure design of front panel

[0048] As Figure 4 The front panel overall structure explosion diagram shows that the display panel A1 is made of acrylic material with a thickness of 3.0MM. The touch key panel A2 is a PCB circuit board with a thickness of 1.6MM. The front panel control mainboard A3 is a PCB circuit board with a thickness of 1.6MM. The fingerprint head A4 waterproof sealing ring is made of silicone. The fingerprint head A5 is a press-type capacitive fingerprint recognition. The mainboard support A6 is made of ABS plastic (black flame retardant). The fingerprint head pressing plate A7 is made of ABS plastic (black flame retardant). The main circuit board back cover A8 is made of ABS plastic (black flame retardant). The front shell A9 is made of forged copper and polished and electroplated. The front fixed plate A10 is made of zinc alloy material. The front rubber pad A11 is made of silicone (black). The mechanical lock head A12.

[0049] This application adopts electronic kit form production test, and then hands over to the assembly production line to produce the whole lock. The electronic kit is composed of 8 parts, including display panel A1, touch key panel A2, front panel control mainboard A3, fingerprint head waterproof sealing ring A4, fingerprint head light transmission support A5, mainboard support A6, fingerprint head pressing plate A7, and main circuit board back cover A8.

[0050] Waterproof measures of this application:

[0051] Waterproofing of circuit board and electronic components by surface three-proof paint coating: three-proof paint is also called circuit board protection oil, coating oil, waterproof glue, insulating paint, and moisture-proof paint. Although the waterproof effect of three-proof paint is limited, it can form a protective film to isolate moisture and a small amount of water

[0052] The structure glue is filled in the outer circle between the display panel A1 and the mainboard support A6 to fix the display panel and prevent dust and water.

[0053] The fingerprint head waterproof sealing ring A4 is used between the display panel A1 and the fingerprint head A5, and is extruded forward by the fingerprint head pressing plate A7.

[0054] The joint gap between the mainboard support A6 and the fingerprint head pressing plate A7, and the mainboard support A6 and the main circuit board back cover A8 is filled with a circle of sealing glue.

[0055] The above measures ensure that the entire electronic kit is a closed space, which guarantees the waterproof and dustproof requirements of the electronic part.

[0056] At the same time

[0057] 1.3 Waterproof structure design of rear panel

[0058] As Figure 5 Knob B1 : Forged copper, polished electroplating. Battery cover B2 : ABS plastic (black flame retardant), fine sand surface. Light transmittance cap B3 : Transparent acrylic sand surface; Rear shell B4 : Forged copper, polished electroplating. Rear light plate B5 : PCB circuit board, thickness 1.0 MM. Switch button B6 : ABS plastic (black flame retardant), fine sand surface. Transmission shaft B7 : Zinc alloy material. Battery box B8 : ABS plastic (black flame retardant). Motor transmission box B9. Rear panel control main board B10 : PCB circuit board, thickness 1.6 MM. Rear support B11 : Zinc alloy material. Mounting plate assembly B12 : Zinc alloy material, used for locking the front panel during assembly. Rear rubber pad B13 : Silicone (black).

[0059] Waterproof measures of rear panel structure:

[0060] Surface nano coating waterproof for circuit board and electronic components: Nano coating is an ideal alternative to three-proof paint, with a thickness of only 2-4 microns, which can form a transparent waterproof layer on the surface of the PCB, with better waterproof effect and heat dissipation performance. Unlike the front panel main control, the front panel electronic suite can form a sealed space, and the rear panel has more transmission structure that cannot guarantee airtightness, so nano coating is used for circuit board waterproofing.

[0061] Battery cover B2 fully wraps battery box B8, and during assembly, battery box B8 and rear shell B4 are filled with a circle of sealant.

[0062] Motor transmission box B9 is mainly realized through mold design. Water is prevented from entering through plugging design.

[0063] Rear rubber pad B13 and front rubber pad in the front panel structure are fixed by extrusion of front and rear fixing screws. It can ensure that the front and rear panels are tightly attached to the door. If the door panel is not flat during the installation of the smart lock, a circle of sealant needs to be filled in the gap.

[0064] 1.4 Transmission structure and principle introduction

[0065] The present application uses a self-developed motor transmission box to control the opening and closing of the smart lock. The transmission gear and part of the electronic control are integrated in the box to reduce the processing difficulty of the smart lock shell and mechanical structure, and facilitate the overall assembly of the smart lock. The overall structure is shown in Figure 6 .

[0066] The angle of rotation of different types of lock bodies is different when the smart lock is opened or closed. In the case of no reverse locking, that is, only the lock tongue is extended, the rotation angle of the lock body is only 90°. In the case of reverse locking, there are generally four rotation angles: 90°, 180°, 270°, and 360°. The detection of the angle relies on the recognition of a Hall sensor. In the figure, 38 is a small magnet. When the motor drives the gear to rotate to the corresponding angle, the Hall sensor electrical signal can be checked to obtain the information. The planetary gear composed of (10) clutch upper bracket, (19) reverse clutch gear shaft, (29) small magnet installed on the clutch upper bracket, (22) clutch spring, (18) forward clutch gear shaft, (20) washer, (8) two (forward / reverse) clutch gears, and (9) clutch lower bracket automatically disengages and disconnects the mechanical transmission of the entire motor transmission box in the case of blockage. There is also a small magnet in the planetary gear for detecting the clutch state of the entire transmission system. There are five Hall sensors in the detection plate, four of which are arranged at an interval of 90° to detect the rotation angle, and one is used to detect the clutch state of the planetary gear.

[0067] 2. Dual-core electronic control system design

[0068] The electronic control system adopts dual-MCU control. As shown in Figure 7 , it is divided into a front panel main control system and a rear panel slave control system: the front panel main control system is designed based on a low-power STM32G071RBT6 processor and is mainly used for human-computer interaction control and information storage. The rear panel slave control system is designed using an STM32G030F6P6 processor and is mainly used for controlling the opening and closing of the lock, networking module communication, etc.

[0069] The front / rear panel (master / slave) control system uses an STM32G0 series as the processor, and its functional features are as follows:

[0070] The STM32G0 series is a high-performance, low-power ARM Cortex-M0+ microcontroller series launched by STMicroelectronics. More than 93% of I / O utilization.

[0071] No decoupling capacitor is needed: STM32G0 series microcontrollers can use only one set of power pins, eliminating the need for external decoupling capacitors and reducing BOM costs.

[0072] No external clock is needed: high-precision timers are integrated internally, which can meet most application requirements, further saving costs. The internal clock tree can be flexibly applied, and the peripheral clock source can be selected. This makes system control and power consumption control more convenient.

[0073] High anti-interference: high anti-instantaneous pulse capability reduces the use of peripheral protection units.

[0074] Multiple low-power modes: Provide multiple low-power modes such as standby, stop, and hibernate to extend battery life.

[0075] Security features: Include firmware IP protection, private code protection, key storage, etc. to enhance system security.

[0076] Front panel main control system implementation functions:

[0077] Responsible for automatic identification of selected function modules and power supply control of optional function modules through MOSFET transistor switch circuit. The combination of optional function modules forms the human-computer interaction function and the lock opening mode selection. Responsible for storing user data, setting parameter data, etc. Communicate with the rear panel control system through UART transmission of AES encrypted data. Its program flowchart is shown in Figure 8

[0078] Rear panel control system implementation functions:

[0079] According to the data sent by the front panel processor, the corresponding processing is carried out, and the system state is fed back in time. Mainly used for controlling the motor to automatically open / close the lock, feeding back the system state of the rear panel to the front panel control system, automatically identifying multiple platforms and multiple networking methods, and converting and feeding back the communication data to the main control system in time, and necessary sound and light prompts. Its program flowchart is shown in Figure 9

[0080] (3) Transmission structure software control subprogram

[0081] This application contains an automatic lock function, which can be set to timing automatic lock and automatic identification lock. Automatic identification lock mainly relies on the geomagnetic module to sense that the door lock reaches the closing position and then realizes automatic lock. The geomagnetic module is a magnetometer, which is a sensor that measures the strength and direction of the magnetic field. It can detect the size of the component in the X, Y, Z three orthogonal coordinate axes direction of the earth's magnetic field. For a fixed geographical location, the geomagnetic field vector can be decomposed into two main components:

[0082] a. The component parallel to the local horizontal plane: also known as the horizontal component, which presents the east-west and south-north direction on the earth's surface. The horizontal component can help determine the geographical direction, for example, the pointer on the compass is under the action of the horizontal component of the geomagnetic field to indicate the north.

[0083] b. The component perpendicular to the local horizontal plane: also known as the vertical component or magnetic inclination component, which reflects the degree of inclination of the geomagnetic field line relative to the local horizontal plane. This component helps to determine the precise direction and strength of the geomagnetic field. ​​

[0084] The transmission control subroutine mainly relies on detecting the electrical signal of the Hall sensor to realize the automatic identification of the left / right opening direction of the intelligent lock and the opening / closing lock function. The automatic identification of the left / right opening direction is controlled in the closed and locked state before the first power-on, and then the power is turned on. The program marks the sensor state at this time, and confirms the program control initial value. The opening / closing lock function also needs to rely on the program control initial value. The motor forward / reverse test is carried out respectively, the position change of the Hall sensor is detected in real time. And timing. Confirm the position mark of the left / right opening direction and the opening / closing lock of the intelligent lock. In the process of opening / closing the lock, after the opening / closing action is completed, the motor needs to be controlled in the reverse direction to rotate to disconnect the planetary gear from the whole transmission clutch, and the mechanical knob can drive the whole structure to realize manual opening / closing door lock. The transmission control subroutine is integrated in the back panel (slave) control system. When the door lock state changes are detected, feedback to the front panel (master) control system in time, and sound and light prompt. The control program flow chart is shown in Figure 10 .

[0085] 3. Intelligent lock multi-platform multi-networking method design

[0086] 3.1 Multi-platform multi-networking automatic identification method

[0087] The multi-platform of the multi-platform multi-networking mainly reflects that multiple wireless communication devices of multiple platforms can be selected, such as self-developed, TTLock (Tongtong lock), TUYA (Tuya) or customer's own communication system. The multi-networking mainly reflects that multiple wireless communication devices can be selected, such as low-power passive WIFI communication module, low-power ZigBee communication module, and low-power Bluetooth communication module. The intelligent lock design initially considers the different needs of customers, as well as the main market of the product is the European and American market, the maintenance or server building of the self-developed wireless communication system and the data security considered by the customer are not very convenient. Therefore, TTLock and TUYA, two public platforms with high acceptance on the market, are selected for networking devices. Similarly, if the customer has his own wireless communication system, it can also be customized and developed.

[0088] The multi-platform multi-networking automatic identification method mainly includes two steps of identification a. Platform identification, b. Wireless module type identification. In the first power-on process of the lock end device, the program will automatically identify. If the identification fails or the wireless module is not connected, the wireless communication function will be turned off. Take the self-developed platform and TUYA (Tuya) platform as an example to explain:

[0089] The protocol format specification of the self-developed communication system when transmitting data is shown in Figure 11 .

[0090] The data sent and received by each frame is encoded in this format. The HEAD: 0x02 is a fixed frame header, which is convenient and fast to locate the position of each frame when analyzing data. LEN is the frame length, which is the sum of the length of the command code and the data. CMD is the command code, and each interaction with the lock end has a defined fixed command code. Both the sent data and the response data have a fixed command code. For example, the unlock request command code is 0x06, and the unlock response command code is 0x86. DATA is the specific data, which can be empty. For example, the unlock command frame does not need to carry additional data, and the DATA field is empty. Adding a user requires carrying user information, which is placed in the DATA field. CRC is the check code, which is calculated by the CRC algorithm. Adding the CRC check code can check the integrity of the data, making the data transmission more accurate and error-free. TAIL: 0xFF is a fixed frame tail.

[0091] The protocol format specification of the TUYA (Tuya) communication system when transmitting data is as shown in Figure 12

[0092] The TUYA Tuya platform protocol format frame header HEAD is two bytes 0x55 and 0XAA, and the version number VER is also two bytes, which is used for protocol upgrade and expansion. The rest is similar to the self-developed platform.

[0093] The communication protocol format of the two platforms is different. The lock end program can distinguish which platform the connected wireless module belongs to according to the difference in the communication protocol. The wireless device type identification is based on the CMD command code in the wireless communication protocol, which is divided into general basic class, device parameter setting class, OTA upgrade class, etc. For example: the different wireless modules of the TUYA Tuya platform have different device parameter class CMD, and the wireless module will not reply to the device parameter class CMD that is not adapted to itself. The difference between the single version and the network version is determined by the binding of the wireless communication device with other devices. The binding process is the same, and the topology structure formed by the different binding devices is different.

[0094] 3.2 Single version system framework introduction

[0095] The single version adopts C / S architecture design. The user interacts with the cloud through the APP client to realize user management, device binding, and device sharing operation. The lock end is equipped with a low-power Bluetooth communication module based on the single version, which provides the ability to interact with the APP client in the near field, realizes the functions of lock user, unlock record, mobile phone unlock, device information, and temporary authorization, and solves the inconvenience of traditional electronic smart locks in management operation, providing a safe and efficient management operation for users.

[0096] 3.3 Introduction of network version system framework

[0097] ​The networking version adopts C / S architecture design, and the user realizes user management, device binding, device sharing, device management and message management operation through the interaction between the APP client and the cloud. The lock end realizes the function of remote interaction with the APP client on the basis of the single machine version by carrying a wireless communication module, and provides the following two connection methods:

[0098] Low-power ZigBee communication module or low-power Bluetooth communication module combined with communication gateway.

[0099] Passive low-power WIFI module is directly connected to the cloud.

[0100] The functions of user under the lock, unlocking record, mobile phone unlocking, device information, temporary authorization, alarm setting and alarm notification are realized, the disadvantages of traditional intelligent lock in remote control and situation awareness are solved, and an extremely convenient management operation is brought to the user.
