Description

Technical Field

[0001] This utility model relates to the field of lock-picking technology, and in particular to a lock-picking device that makes manual unlocking easier and less strenuous. Background Technology

[0002] Currently, there is a type of unlocking device on the market, mainly used to replace manual key turning for automatic unlocking. This type of device typically consists of a fixed base and a rotating body: the fixed base has a clearance hole for the key to pass through, and the rotating body has a slot to receive the key; the fixed base is equipped with a gear ring structure, and a drive motor is mounted on the rotating body. The motor is connected to an output gear, and the output gear and the gear ring form a transmission engagement. In practical applications, the fixed base is usually fixed to the door or lock cylinder body. The key on the lock cylinder passes through the clearance hole of the fixed base and is inserted into the slot of the rotating body. When the motor starts, the output gear and the gear ring drive the rotating body to rotate. At this time, the rotating body applies torque to the key through the inner wall of its slot, thereby completing the automatic unlocking operation.

[0003] However, such unlocking devices have significant drawbacks: in manual unlocking scenarios, when the user manually rotates the rotating body, they need to overcome the resistance generated by the reverse drive mechanism. This resistance includes the resistance generated by the output gear rotating relative to the gear ring, as well as the mechanical resistance generated by the output gear driving the motor rotor in the reverse direction. This directly leads to the laborious and inconvenient manual operation process. Utility Model Content

[0023] Reference Figures 1 to 4 A more labor-saving manual unlocking device according to an embodiment of the present invention includes a fixed base 100, a first rotating body 300, and a second rotating body 800. The fixed base 100 has a first key clearance hole 110. The first rotating body 300 is rotatably mounted on the fixed base 100 and has a second key clearance hole 310, which is opposite to and communicates with the first key clearance hole 110. The second rotating body 800 is rotatably mounted on the first rotating body 300 and has a key slot 810. Opposite to the first key clearance hole 110, a driving device 400 is provided between the first rotating body 300 and the second rotating body 800. The driving device 400 is used to drive the second rotating body 800 to rotate relative to the first rotating body 300. A manual operating device 500 is provided between the first rotating body 300 and the fixed base 100. The manual operating device 500 can lock the first rotating body 300 so that the first rotating body 300 is stationary relative to the fixed base 100, and the manual operating device 500 can unlock the first rotating body 300 so that the first rotating body 300 can rotate relative to the fixed base 100.

[0024] In practical applications, the fixing base 100 can be fixed to the door or the lock cylinder on the door body by means of bolt connection, glue bonding, welding, clamp connection, snap-fit, etc. The key on the lock cylinder can be inserted into the key slot 810 after passing through the first key clearance hole 110 and the second key clearance hole 310. Therefore, when the second rotating body 800 rotates relative to the fixing base 100, the second rotating body 800 can twist the key through the inner wall of the key slot 810, thereby realizing the unlocking of the lock cylinder.

When automatically unlocking, the manual operation device 500 is in the locked state of the first rotating body 300. At this time, the drive device 400 can drive the second rotating body 800 to rotate, thereby driving the key to rotate and realize automatic unlocking. When manual unlocking is required, the user can unlock the first rotating body 300 through the manual operation device 500, and then make the first rotating body 300, the second rotating body 800 and the drive device 400 rotate together, thereby driving the key to rotate and realize manual unlocking. Moreover, there is no need to overcome the resistance formed by the reverse driving of the drive device 400 during the manual unlocking process, thus making the manual unlocking of the unlocking device easier and less strenuous.

[0026] For traditional locks that require key unlocking, the unlocking device provided by this utility model can automate and make traditional locks intelligent without changing their structure, while retaining the emergency unlocking method of manual unlocking.

[0027] Reference Figure 1 , Figure 2 and Figure 3 According to some embodiments of the present invention, the manual operating device 500 includes an operating member 510, a locking member 520, and a reset structure 530. The operating member 510 is movably mounted on the fixed base 100 or the first rotating body 300. The locking member 520 is movably disposed between the fixed base 100 and the first rotating body 300. The locking member 520 has a locked position and an unlocked position. When the locking member 520 is in the locked position, the locking member 520 connects the fixed base 100 and the first rotating body 300 to lock the first rotating body 300. When the locking member 520 is in the unlocked position, the locking member 520 disengages from the fixed base 100 or the first rotating body 300 to unlock the first rotating body 300. The operating member 510 is used to drive the locking member 520 from the locked position to the unlocked position, and the reset structure 530 is used to drive the locking member 520 from the unlocked position to the locked position. With the above settings, the user only needs to operate the operating component 510 to unlock the first rotating body 300, and the locking of the first rotating body 300 can be automatically completed by the reset structure 530, making the operation more convenient.

[0028] Reference Figures 1 to 3According to some embodiments of this utility model, the fixed base 100 is provided with a connecting sleeve 200, which is rotatably inserted into the second key clearance hole 310. The connecting sleeve 200 is provided with a mounting groove 210. A mounting hole 320 is opened on the outer periphery of the first rotating body 300. The operating member 510 is slidably installed in the mounting hole 320. One end of the locking member 520 is slidably inserted into the mounting groove 210. When the locking member 520 is in the locked position, the mounting groove 210 is opposite to the mounting hole 320 and the locking member 520 is inserted into the mounting hole 320. When the locking member 520 is in the unlocked position, the locking member 520 is disengaged from the mounting hole 320. With the above configuration, the user only needs to press the operating member 510 to switch the locking member 520 from the locked position to the unlocked position, which is convenient and simple to operate.

[0029] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the reset structure 530 includes an elastic sheet, which is at least partially disposed in the mounting groove 210 and abuts against the locking member 520. Thus, the reset structure 530 can push the locking member 520 into the mounting hole 320 to lock the first rotating body 300.

[0030] In the specific implementation process, the opposite side walls of the mounting groove 210 are provided with insertion grooves 211, and the opposite ends of the elastic sheet are inserted into the insertion grooves 211 one by one, and the locking member 520 abuts against the middle part of the elastic sheet.

[0031] It should be noted that in some other embodiments, the reset structure 530 may also be configured in other ways. For example, the reset structure 530 may include two magnets, one of which is disposed in the mounting groove 210 and the other is disposed in the locking member 520. The two magnets repel each other to push the locking member 520 into the mounting hole 320.

[0032] It is conceivable that the aforementioned operating element 510 and locking element 520 can also be configured in the following ways: for example, the fixed base 100 is provided with an annular groove, and the first rotating body 300 is provided with multiple slots arranged in an annular pattern, with the slots opposite to the annular groove. The operating element 510 is sleeved on the first rotating body 300, and the locking element 520 is annular and slidably inserted into the annular groove. The reset structure 530 is a spring provided in the annular groove. The locking element 520 is provided with multiple locking parts. The reset structure 530 is used to push the locking element 520 toward the first rotating body 300 so that the locking parts are locked into the slots one by one, thereby locking the first rotating body 300. The user can push the operating element 510 toward the fixed base 100 so that the operating element 510 pushes the locking element 520 away from the first rotating body 300, thereby disengaging the locking parts from the slots and unlocking the first rotating body 300.

[0033] It should be noted that in some other embodiments, the manual operating device 500 may also adopt other configurations. For example, the manual operating device 500 includes a knob with a screw on it. The screw passes through the first rotating body 300 and abuts against the fixed seat 100. When the knob is tightened, the screw can abut tightly against the fixed seat 100, thereby generating damping that prevents the first rotating body 300 from rotating relative to the fixed seat 100, thus locking the first rotating body 300. When the knob is loosened, the screw can loosen the fixed seat 100, allowing the first rotating body 300 to rotate relative to the fixed seat 100.

[0034] Reference Figures 1 to 3 According to some embodiments of this utility model, the fixed base 100 is provided with a connecting sleeve 200, which is rotatably inserted into the second key clearance hole 310. One end of the second rotating body 800 is rotatably inserted into the connecting sleeve 200, and a first limiting structure is provided between one end of the second rotating body 800 and the fixed base 100. The first limiting structure is used to restrict the second rotating body 800 from detaching from the connecting sleeve 200. With the above configuration, the second rotating body 800 can be rotatably installed on the first rotating body 300, and the first limiting structure can be used to prevent the second rotating body 800 from detaching from the connecting sleeve 200.

[0035] Reference Figure 1 and Figure 3 According to some embodiments of this utility model, the first limiting structure includes a limiting plate 600, which is connected to one end of the second rotating body 800. The limiting plate 600 is rotatably installed between the fixed base 100 and the connecting sleeve 200. With the above configuration, the first limiting structure can prevent the second rotating body 800 from disengaging from the connecting sleeve 200 and ensure that the second rotating body 800 is simple and convenient to assemble.

[0036] Reference Figure 3 The limiting plate 600 has a third key clearance hole 610, which is opposite to the key slot 810 so that the key can pass through the third key clearance hole 610 and be inserted into the key slot 810.

[0037] In other embodiments, the first limiting structure may also adopt other configuration methods. For example, the first limiting structure includes a pin inserted into the connecting sleeve 200 and an annular limiting groove disposed on the second rotating body 800, with the pin inserted into the annular limiting groove.

[0038] Reference Figure 1 and Figure 4According to some embodiments of this utility model, the second rotating body 800 abuts against the end of the first rotating body 300 away from the fixed base 100 to prevent the first rotating body 300 from disengaging from the connecting sleeve 200. With the above arrangement, the second rotating body 800 can be used to prevent the first rotating body 300 from disengaging from the connecting sleeve 200, and ensure that the first rotating body 300 is simple and convenient to assemble.

[0039] Of course, in other embodiments, other methods can be used to prevent the first rotating body 300 from detaching from the connecting sleeve 200. For example, a second limiting structure is provided between the first rotating body 300 and the fixed base 100. The second limiting structure is used to restrict the first rotating body 300 from detaching from the connecting sleeve 200. In specific implementation, the second limiting structure may include a pin, which passes through the first rotating body 300. The connecting sleeve 200 is provided with an annular limiting groove, and the pin is inserted into the annular limiting groove.

[0040] Reference Figure 1 and Figure 3 According to some embodiments of this utility model, a plane bearing 700 is installed at one end of the second rotating body 800, and a step portion 330 is provided on the inner wall of the second key clearance hole 310. The plane bearing 700 is disposed between the step portion 330 and the connecting sleeve 200. With the above arrangement, the second rotating body 800 can rotate more smoothly and steadily relative to the first rotating body 300.

[0041] Reference Figure 1 and Figure 3 According to some embodiments of this utility model, the driving device 400 includes a motor 410 and a gear ring 420. The gear ring 420 is fixedly disposed on the first rotating body 300, and the motor 410 is mounted on the second rotating body 800. The motor 410 is driven by an output gear 430, which engages with the gear ring 420. Thus, the motor 410 can drive the output gear 430 to rotate, and the engagement between the output gear 430 and the gear ring 420 drives the second rotating body 800 to rotate relative to the first rotating body 300, thereby achieving automatic unlocking.

[0042] According to some embodiments of this utility model, the second rotating body 800 is equipped with a battery (not shown in the figure) and a control device (not shown in the figure). The control device is electrically connected to the motor 410 and the battery. Thus, the battery can supply power to the control device and the motor 410, and the control device controls the operation of the motor 410, thereby realizing automatic unlocking. The motor 410, battery, and control device are all mounted on the second rotating body 800, which avoids relative rotation between the motor 410 and the battery / control device, facilitates the electrical connection between the motor 410, battery, and control device, and effectively reduces the occurrence of poor contact faults.

[0043] In the specific implementation process, in order to achieve automated and intelligent unlocking, the control device is equipped with one or more unlocking modules such as button module, fingerprint recognition module, voice recognition module, face recognition module, remote communication module, and near-field communication module to realize automatic unlocking methods such as remote communication unlocking, near-field communication unlocking, button unlocking, or biometric unlocking.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
