Description

Technical Field

[0001] This utility model relates to the field of door lock technology, and in particular to a main structure of an intelligent electronic lock. Background Technology

[0002] Traditional electronic door locks typically consist of lock bodies on both the inner and outer sides of the door. Their bolt extension and retraction directions are singular and fixed, requiring strict adherence to the door's opening direction during installation. This structure reveals significant drawbacks in practical use: First, installers must pre-determine the door's opening direction to correctly install the lock body. Incorrect judgment of the inner / outer direction can lead to misalignment of the bolt's movement with the door frame's strike plate, resulting in a serious problem of inability to lock properly. Second, existing door locks lack directional self-adaptive capability. When users need to change the door's opening direction due to renovations, the entire lock body structure must be replaced, resulting in resource waste and increased operating costs.

[0003] While some existing electric locks attempt to address the directional adaptability issue, they generally suffer from the following technical bottlenecks: 1. The use of a single sensor carries the risk of misjudgment, making it impossible to accurately identify the forward and reverse rotation of the knob; 2. The lack of precise control over the lock pin's rotation angle leads to unstable bolt extension and retraction; 3. The absence of a linkage control mechanism between the inner and outer lock bodies makes rapid unlocking difficult in emergencies. Especially when the door's installation direction is unclear, traditional locks cannot automatically identify the opening direction and adjust the bolt's movement accordingly, severely limiting their applicability and level of intelligence.

[0004] This utility model is based on the above-mentioned circumstances. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides a main structure for an intelligent electronic lock that can identify the direction of door opening.

[0006] This utility model is achieved through the following technical solution:

[0007] A smart electronic lock main structure includes an inner lock body installed on the inside of the door, an outer lock body installed on the outside of the door, and a locking pin structure located between the inner and outer lock bodies that can drive the lock tongue to extend or retract when rotated. The inner lock body contains a circuit board and a power supply. The inner lock body has a knob that can drive the locking pin structure to rotate. The knob has a rotating component that can drive it to rotate. The inner lock body also contains a motor that can drive the rotating component to rotate and an identification device that can identify the door opening direction. The identification device includes a first optocoupler sensor, a Hall sensor, and a second optocoupler sensor arranged in sequence along the circumference. The rotating component has a sensing element that can follow the rotation of the rotating component and is adapted to sense the first and second optocoupler sensors. The rotating component also has a magnet that can follow the rotation of the rotating component and is adapted to sense the Hall sensor. The outer lock body has an unlocking mechanism that can control the rotation of the motor to unlock the door.

[0008] As described above, in the main structure of an intelligent electronic lock, the rotating component includes a drive gear fixedly connected to the motor shaft and a driven gear connected to the knob, wherein the drive gear and the driven gear mesh with each other.

[0009] In the above-described intelligent electronic lock main structure, the first optocoupler sensor is located to the left of the Hall sensor, and the second optocoupler sensor is located to the right of the Hall sensor.

[0010] In the intelligent electronic lock main structure described above, the central angle between the first optocoupler sensor and the Hall sensor is 90°, and the central angle between the second optocoupler sensor and the Hall sensor is 90°.

[0011] As described above, the main structure of an intelligent electronic lock includes a locking block on the inner side of the knob, a turntable between the knob and the driven gear, a locking groove on the turntable that engages with the locking block, an arc-shaped limiting groove on the turntable, and a limiting block on the driven gear that can extend into the arc-shaped limiting groove.

[0012] The main structure of the intelligent electronic lock described above includes an unlocking mechanism comprising an electronic key device that controls the operation of a motor to unlock the lock.

[0013] The main structure of the intelligent electronic lock described above includes an unlocking mechanism comprising a fingerprint lock device capable of controlling the operation of a motor to unlock the lock.

[0014] The main structure of the intelligent electronic lock described above includes an unlocking mechanism comprising a facial recognition device that controls the operation of a motor to unlock the lock.

[0015] As described above, the main structure of a smart electronic lock includes a doorbell call device inside the inner lock body, and a switch button for the doorbell call device on the outer lock body.

[0016] As described above, the main structure of a smart electronic lock also includes a USB charging port on the inner lock body and / or the outer lock body.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] This product utilizes the coordinated detection of a first optocoupler sensor, a Hall sensor, and a second optocoupler sensor, combined with dual-mode signal recognition from the sensing element and the magnet, to accurately determine the knob's rotation direction, automatically match the door's opening direction, and save the result. During installation, there's no need to pre-distinguish between the door's inward and outward opening directions, reducing installation errors; and when changing the door's opening direction, there's no need to replace the lock body, significantly improving its applicability.

[0019] The circuit board controls the motor's rotation angle and torque to precisely adjust the bolt extension and retraction stroke, preventing bolt jamming caused by mechanical wear. A Hall effect sensor monitors magnet position changes in real time, and combined with phase difference detection by an optocoupler sensor, forms a closed-loop feedback control system to ensure the bolt automatically stops once it reaches its designated position, preventing overload.

[0020] The first and second optocoupler sensors determine the rotation direction by the timing of sensor blockage; the Hall sensor verifies the rotation angle by changes in magnetic signal intensity. This dual verification mechanism eliminates the risk of false triggering by a single sensor, thus improving reliability. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] like Figures 1 to 8 The main structure of the intelligent electronic lock shown includes an inner lock body 1 installed on the inside of the door, an outer lock body 2 installed on the outside of the door, and a locking pin structure 3 located between the inner lock body 1 and the outer lock body 2, which can drive the lock tongue to extend or retract when rotated. The inner lock body 1 is provided with a circuit board 4 and a power supply 5 for powering the circuit board 4. The inner lock body 1 is provided with a knob 6 that can drive the locking pin structure 3 to rotate. The knob 6 is provided with a rotating component 7 that can drive it to rotate. The inner lock body 1 is also provided with a motor 71 that can drive the rotating component 7 to rotate and an identification device that can identify the door opening direction. The identification device includes a first optical coupler sensor 81, a Hall sensor 82 and a second optical coupler sensor 83 arranged in sequence along the circumference. The rotating component 7 is provided with a sensing component 72 that can follow the rotation of the rotating component 7 and is adapted to sense the first optical coupler sensor 81 and the second optical coupler sensor 83. The rotating component 7 is also provided with a magnet 73 that can follow the rotation of the rotating component 7 and is adapted to sense the Hall sensor 82. The outer lock body 2 is provided with an unlocking mechanism that can control the rotation of the motor 71 to unlock the door.

[0032] This product uses the coordinated detection of the first optocoupler sensor 81, the second optocoupler sensor 83, and the Hall sensor 82, combined with dual-modal signal recognition technology, to accurately determine the knob rotation direction. It automatically adapts to and memorizes the door opening and closing direction, eliminating the need to predict the installation direction and requiring no replacement of the lock body during modification. It adopts a closed-loop control system to adjust the torque of the motor 71 and the bolt stroke in real time. Through a dual mechanism of phase difference detection and magnetic signal verification, it ensures precise operation, effectively preventing mechanical jamming and overload problems, and significantly improving installation fault tolerance and operational reliability.

[0033] Motor 71, first optocoupler sensor 81, Hall sensor 82 and second optocoupler sensor 83 are all electrically connected to circuit board 4.

[0034] During use, in the initialization state, the smart lock program on circuit board 4 will automatically identify and judge the door opening direction. If it is a right-opening door, when motor 71 turns left to drive knob 6 to control the lock tongue to open to the right, the output shaft of motor 71 will not turn, thereby increasing the torque of motor 71. At this time, Hall sensor 82 detects the armature current of motor 71 and feeds it back to the control program. After automatic recognition, it will automatically control motor 71 to rotate in the opposite direction. When the sensor 72 reaches the second optocoupler sensor 83, it will be determined as unlocking. Conversely, if it is a left-opening door, motor 71 turns left, and when the sensor 72 reaches the first optocoupler sensor 81, it will be determined as unlocking.

[0035] In one embodiment, a first optocoupler sensor 81 is disposed to the left of the Hall sensor 82, and a second optocoupler sensor 83 is disposed to the right of the Hall sensor 82. The central angle between the first optocoupler sensor 81 and the Hall sensor 82 is 90°, and the central angle between the second optocoupler sensor 83 and the Hall sensor 82 is 90°.

[0036] In one embodiment, the rotating component 7 includes a driving gear 74 fixedly connected to the shaft of the motor 71 and a driven gear 75 connected to the knob 6, wherein the driving gear 74 and the driven gear 75 mesh with each other. Further, a locking block 61 is provided inside the knob 6, and a turntable 62 is provided between the knob 6 and the driven gear 75. The turntable 62 has a locking groove 621 that engages with the locking block 61, and an arc-shaped limiting groove 622. The driven gear 75 has a limiting block 76 that can extend into the arc-shaped limiting groove 622. The driven gear 75, the limiting block 76, and the sensing component 72 are an integral structure, and the sensing component 72 is L-shaped.

[0037] In one embodiment, the unlocking mechanism includes an electronic key device 90 that controls the operation of the motor 71 to unlock the lock. The electronic key device 90 is a conventional electronic key device 90 used on electronic locks, and will not be described in detail here.

Furthermore, a light source can be provided inside the switch button 931 so that its illumination makes it easy for visitors to identify and press the bell.
