Description

Technical Field

[0001] This invention relates to the field of electronic lock technology, specifically to a multi-state electronic lock. Background Technology

[0002] Currently, most electronic locks on the market only offer a single unlocking mode, relying either on electronic authorization or a mechanical key, resulting in limited functionality. Traditional electronic locks also cannot flexibly switch unlocking modes to meet the management needs of different areas. Furthermore, the relatively fixed structural design of traditional electronic locks necessitates redesigning the mold for functional adjustments, increasing production costs, extending product development cycles, and hindering modular assembly and functional expansion, which is detrimental to batch management and zone control. In addition, traditional electronic locks often cannot quickly switch to emergency unlocking mode after a mains power outage, causing significant inconvenience to users. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a multi-state electronic lock that can flexibly switch working states, realize multiple unlocking modes, and adopt a modular design to reduce production and maintenance costs and meet the needs of batch management in different areas.

[0004] The technical solution adopted by this invention is as follows: This invention provides a multi-state electronic lock, comprising a lock body base, a main structure, a lock cylinder structure, a bolt, a drive assembly, and a control assembly. The main structure is disposed on the lock body base, and the lock cylinder structure is disposed on the main structure. The lock body base has a slot, and a guide shell is disposed within the slot. The bolt is slidably disposed within the guide shell and cooperates with the lock cylinder structure. An electronic control box is disposed on the lock body base. The drive assembly is disposed within the electronic control box and is used to drive the bolt to move at least three predetermined positions. The control assembly includes a circuit board, a capacitor, and a main control unit disposed on the circuit board. The main control unit has multiple pre-stored control programs. The control assembly is electrically connected to the drive assembly and is used to control the action of the drive assembly according to the selected control program, thereby positioning the bolt in different predetermined positions to define different working states of the electronic lock.

[0005] Furthermore, the at least three predetermined positions of the latch include: a first position, a second position, and a third position; wherein the first position corresponds to the latch being at its foremost end, the third position corresponds to the latch being at its rearmost end, and the second position is located between the first position and the third position.

[0006] Furthermore, the main structure includes a handle, a handle pivot, a connecting shaft, a bolt pivot, a bolt, and a top and bottom rod. The handle pivot is rotatably mounted on the lock body base, and the connecting shaft is rotatably mounted on the handle pivot. The handle is fixedly connected to the connecting shaft. A torsion spring is sleeved on the connecting shaft, and the two ends of the torsion spring are respectively fixed to the handle and the handle pivot. A top and bottom rod drive box is provided on the lock body base. The bolt pivot is rotatably mounted inside the top and bottom rod drive box and connected to the handle pivot. The bolt is mounted on the bolt pivot. The top and bottom rods are slidably connected to the top and bottom rod drive box. The top and bottom rods have toothed grooves, and a top and bottom rod gear is sleeved on the bolt pivot. The top and bottom rods mesh with the top and bottom rod gear through the toothed grooves.

[0007] Furthermore, the lock cylinder structure includes a lock cylinder, a lock cylinder shaft, and a lock disc. The handle is provided with a lock cylinder groove, the lock cylinder is rotatably disposed within the lock cylinder groove, the lock cylinder shaft is disposed on the lock cylinder, the lock disc is disposed on the lock cylinder shaft, and the bolt is provided with a latch. When the bolt is in the first position, the latch engages with the lock disc. When the bolt is in the third position, the latch is completely separated from the lock disc. When the bolt is in the second position, the latch can selectively engage or disengage from the lock disc.

[0008] Furthermore, the latch is provided with a spring plunger, which is used to position the latch in a second position. The spring plunger includes a second spring and a steel ball. The second spring is provided on the latch, and the steel ball is provided on the second spring. The guide shell is provided with a positioning groove, and the steel ball is engaged in the positioning groove.

[0009] Furthermore, the drive assembly includes a motor and a push rod that is driven by the motor. The motor is located in an electronic control box and controlled by a control assembly. The push rod is linked to the rear end of the latch. A first spring is also provided between the latch and the guide shell.

[0010] Furthermore, the electronic control box is equipped with a status indicator component, which includes a light guide column and an LED light electrically connected to the circuit board, for optical indication according to the current working status of the electronic lock. The electronic control box is also equipped with a detection switch, which is used to detect whether unlocking authorization has been obtained.

[0011] Furthermore, a lock cylinder cover plate is slidably provided on the handle to cover the lock cylinder structure.

[0012] Furthermore, the handle is provided with a groove to facilitate the user in opening the handle.

[0013] The present invention also provides a control method for the above-mentioned multi-state electronic lock, comprising the following steps:

[0014] S1: Configure or select a control program for the electronic lock;

[0015] S2: The control component controls the drive component to position the bolt to the corresponding predetermined position according to the selected control program, and enters the working state;

[0016] S3: Upon receiving an unlocking or state switching command, the control component controls the drive component to move the bolt between the predetermined positions according to the current program logic, and / or combines the operation of the mechanical key to complete the corresponding unlocking operation.

[0017] The operating state includes at least one of the following: electronically controlled unlocking state, dual-channel unlocking state, and emergency unlocking state;

[0018] In the electrically controlled unlocked state, the bolt is initially located in the first position and only performs electronic unlocking in response to valid electronic authorization commands;

[0019] In the electrically controlled unlocked state, when the main power supply is cut off, it automatically enters the emergency unlocked state. In the emergency unlocked state, the control component uses the electrical energy of the capacitor to drive the lock tongue to move to the second position, allowing emergency mechanical unlocking by mechanical key operation.

[0020] In the dual-channel unlocking state, the latch is initially located in the second position and can be electronically unlocked in response to a valid electronic authorization command, or mechanically unlocked in response to a mechanical key operation.

[0021] The beneficial effects achieved by the present invention using the above structure are as follows:

[0022] This invention achieves multiple operating states, including electrically controlled unlocking, dual-channel unlocking, and emergency unlocking, by controlling the movement of the locking bolt to three predetermined positions. It can meet unlocking needs in different scenarios, and is particularly suitable for management scenarios with different areas and access permissions.

[0023] This invention employs a modular structural design, allowing for the implementation of different functions by adding or removing components and writing different control programs. It eliminates the need for new molds, reducing production and R&D costs while simultaneously improving the product's versatility and interchangeability.

[0024] When the main power supply fails, the control component can use the capacitor's energy to drive the bolt to the second position, supporting emergency unlocking with a mechanical key. This avoids the problem of traditional electronic locks being unable to open after a power outage, improving security and reliability.

[0025] The status indicator component inside the electronic control box can visually display the current operating status of the electronic lock through LED lights and light guides. Simultaneously, the detection switch can detect unlocking authorization in real time, facilitating batch monitoring and management by administrators. Attached Figure Description

The drive assembly 5 includes a motor 51 and a push rod 52 that is driven by the motor 51. The motor 51 is located in the electronic control box 12 and is controlled by the control assembly 6. The push rod 52 is linked to the rear end of the lock tongue 4. A first spring 41 is also provided between the lock tongue 4 and the guide shell 111.

[0046] The control component 6 includes a circuit board 61, a capacitor 62, and a main control unit mounted on the circuit board 61. The main control unit has multiple control programs pre-stored. The control component 6 is electrically connected to the drive component 5 and is used to control the drive component 5 according to the selected control program, thereby positioning the bolt 4 in different predetermined positions to define different working states of the electronic lock.

[0047] The locking tongue 4 has at least three predetermined positions: a first position, a second position, and a third position. The first position corresponds to the locking tongue 4 at its foremost point, the third position corresponds to the locking tongue 4 at its rearmost point, and the second position is located between the first and third positions. When the locking tongue 4 is in the first position, the latch 43 engages with the lock disc 33.

When the locking tongue 4 is in the second position, the latch 43 can selectively engage or disengage from the lock disc 33. The lock body base 1 is provided with a slot 11, and a guide shell 111 is provided inside the slot 11. The locking tongue 4 is slidably disposed within the guide shell 111.

[0048] The latch 4 is provided with a spring plunger 42, which is used to position the latch 4 in a second position. The spring plunger 42 includes a second spring 421 and a steel ball 422. The second spring 421 is provided on the latch 4, and the steel ball 422 is provided on the second spring 421. The guide shell 111 is provided with a positioning groove, and the steel ball 422 is engaged in the positioning groove.

[0049] The electronic control box 12 is equipped with a status indicator component, which includes a light guide column 121 electrically connected to the circuit board 61 and an LED light, for optical indication according to the current working status of the electronic lock. The electronic control box 12 is also equipped with a detection switch 122, which is used to detect whether unlocking authorization has been obtained.

[0050] The control method for the multi-state electronic lock described above includes the following steps:

[0051] S1: Configure or select a control program for the electronic lock;

[0052] S2: According to the selected control program, the control component 6 controls the drive component 5 to position the locking tongue 4 to the corresponding predetermined position and enter the working state;

[0053] S3: Upon receiving an unlocking or state switching command, the control component 6 controls the drive component 5 to move the bolt 4 between predetermined positions according to the current program logic, and / or combines it with the mechanical key operation to complete the corresponding unlocking operation.

[0054] The operating status includes at least one of the following: electrically controlled unlocked status, dual-channel unlocked status, and emergency unlocked status;

[0055] In the electrically controlled unlocked state, the bolt 4 is initially in the first position and only responds to valid electronic authorization commands to perform electronic unlocking;

[0056] In the electrically controlled unlocking state, when the main power supply is cut off, it automatically enters the emergency unlocking state. In the emergency unlocking state, the control component 6 uses the electrical energy of the capacitor 62 to drive the lock tongue 4 to move to the second position, allowing emergency mechanical unlocking by mechanical key operation.

[0057] In the dual-channel unlocking state, the latch 4 is initially in the second position, and can be electronically unlocked in response to a valid electronic authorization command, or mechanically unlocked in response to a mechanical key operation.

[0058] In practical use, in the electrically controlled unlocking state: When the electrically controlled unlocking program is selected for the electronic lock, the control component 6 controls the motor 51 to drive the push rod 52, positioning the bolt 4 to the first position. At this time, the latch 43 engages with the lock disc 33. After the detection switch 122 detects a valid electronic authorization command, the motor 51 drives the push rod 52 to move the bolt 4, causing the latch 43 to separate from the lock disc 33, completing the electronic unlocking. In this state, the mechanical key cannot unlock the lock.

[0059] Emergency unlocking state: When the main power is cut off in the electrically controlled unlocking state, the control component 6 automatically uses the electrical energy of capacitor 62 to control motor 51 to drive the bolt 4 to the second position. At this time, the mechanical key is used to rotate the lock cylinder 31 180°, the lock cylinder shaft 32 drives the lock disc 33 to rotate, the latch 43 separates from the lock disc 33, and the emergency mechanical unlocking is completed.

[0060] Dual-channel unlocking state: When the dual-channel unlocking program is selected for the electronic lock, the control component 6 controls the motor 51 to position the bolt 4 to the second position. The user can complete electronic unlocking by having the motor 51 drive the bolt 4 through a valid electronic authorization command; alternatively, the user can directly use a mechanical key to rotate the lock cylinder 31 180°, causing the lock disc 33 to separate from the latch 43, thus completing mechanical unlocking.

[0061] Different operating states of the electronic lock can be displayed through the status indicator component. The control component 6 controls the LED lights to turn on or off or change color according to the current operating state, and the light is transmitted through the light guide column 121, making it easy for users to intuitively understand the status of the electronic lock.

[0062] In summary, this invention achieves multiple operating states, including electrically controlled unlocking, dual-channel unlocking, and emergency unlocking, by controlling the movement of the bolt 4 in three predetermined positions. It can meet unlocking needs in different scenarios, and is particularly suitable for management scenarios with different areas and access permissions. This invention adopts a modular structural design, allowing for different functions to be achieved by adding or removing accessories and writing different control programs. It eliminates the need for new molds, reducing production and R&D costs while improving product versatility and interchangeability. When the main power is lost, the control component 6 can use the energy of capacitor 62 to drive the bolt 4 to the second position, supporting emergency unlocking with a mechanical key. This avoids the problem of traditional electronic locks being unable to open after a power outage, improving security and reliability. The status indicator component inside the electronic control box 12 can visually display the current operating status of the electronic lock through LED lights and light guide columns 121. Simultaneously, the detection switch 122 can detect unlocking authorization in real time, facilitating batch monitoring and management by administrators.
