Description

Technical Field

[0001] This utility model relates to an electromechanical dual-purpose lock, and more particularly to a multifunctional electromechanical dual-purpose lock. Background Technology

[0002] Chinese Patent Publication No. CN221194632U, published on June 21, 2024, discloses a compact mechanical-electronic dual-purpose ball lock, including a front ball lock body, a rear ball lock body, and a transmission rod assembly connecting the front and rear ball lock bodies. The front ball lock body includes a front housing, within which a lock cylinder structure and a clutch structure are provided. The clutch structure is driven by the lock cylinder structure to engage with the transmission rod assembly. The lock cylinder structure includes a lock cylinder assembly, the output end of which is driven by a slidably disposed push block. The clutch structure includes a clutch head and a clutch plate. The clutch head is fixedly connected to one end of the transmission rod assembly, and the clutch plate is slidably connected to one side of the push block. A transmission lever is also provided between the push block and the clutch plate. The push block pushes the transmission lever to move, causing the clutch plate to move toward the clutch head and engage with it. The ball lock in this structure has a gear adjustment knob on the rear ball lock body. However, since the main control circuit board is located on the front ball lock body, a relatively complex transmission structure is required to enable the adjustment knob on the rear ball lock body to control the gear key on the main control circuit board of the front ball lock body.

The front end of the transmission shaft 70 is in a transmission engagement with the transmission sleeve 44. The rear end of the front handle 2 is provided with a rear cavity 23. The front handle 2 is sleeved on the front rotating seat 4 through the rear cavity 23 and is fixedly connected to the front rotating seat 4. The lock cylinder 1 and the electric clutch mechanism 6 are both in a transmission engagement with the transmission shaft 70 through the transmission sleeve 44.

[0037] The transmission sleeve 44 has an insertion hole 444 at its front end, and a stop block is provided inside the insertion hole 444. The lock cylinder 1 is located on the central axis of the front handle 2. The lock cylinder 1 has a paddle 11 at its rear end, which is inserted into the insertion hole 444. The paddle 11 rotates to actuate the stop block, thereby causing the transmission sleeve 44 to rotate. The transmission sleeve 44 has a clutch groove 441 on one side. The electronically controlled clutch mechanism 6 includes a motor 61, a transmission device, and a clutch block 45. The clutch block 45 is slidably mounted on the front rotating seat 4.

There are two magnetic blocks, namely a first magnetic block 443 and a second magnetic block 446, which are symmetrically distributed on the front end face of the transmission sleeve 44. When the transmission sleeve 44 rotates forward or backward, one magnetic block passes through the area directly opposite the Hall sensor 51, thereby forming an unlocking signal that is fed back to the main control circuit board 9. The main control circuit board 9 can issue a reminder signal (such as sending a signal to the sound prompt circuit to emit a sound to prompt unlocking). The magnetic block and the clutch block 45 are distributed on opposite sides of the sleeve hole 412 of the front rotating seat 4. The cover plate 46 spans the sleeve hole 421 and has a clearance hole corresponding to the area directly opposite the sleeve hole 412 and the Hall sensor 51.

[0041] The front sleeve 41 of the front rotating seat 4 passes through the front fixed seat 101 and is connected to the front chuck 42 for transmission. The front chuck 42 is in a limiting fit with the front fixed seat 101. A return torsion spring is also fitted on the outside of the front sleeve 41, and the two ends of the return torsion spring abut against the front chuck 42 and the front fixed seat 101 respectively. The transmission shaft 70 is a square tube shaft, and a bushing 43 is positioned on the outside of the entire section of the square tube shaft. The bushing 43 is inserted into the front sleeve 41 and rotates with the front sleeve 41.

A return torsion spring is also sleeved on the outside of the rear sleeve 81, and the two ends of the return torsion spring abut against the rear chuck 83 and the rear fixed seat 201, respectively.

[0043] The battery box 84 has a slot 841 at its rear end. The main control circuit board 9 is inserted into the slot 841. The reset switch and the function position switch are respectively located on the outer surface and rear end of the main control circuit board 9. The outer side of the slot 841 has an open portion corresponding to the reset switch. The push button 32 or knob is located at the rear end of the rear handle 3. The center of the rear end of the rear handle 3 has a cover plate 31 corresponding to the outer side of the locking screw 33.

[0044] Its working principle is as follows: In normal mode, the fingerprint recognition module 21 and the password recognition module can work normally and identify the user's identity. After correct identification, the electronic clutch mechanism 6 is controlled to move, and the clutch block 45 is inserted into the clutch groove 441 of the transmission sleeve 44, realizing the transmission between the front rotating seat 4 and the transmission sleeve 44 on the transmission shaft 7. By rotating the front handle 2, the transmission shaft 7 can be driven to rotate, thereby controlling the lock body 30 to unlock. In addition, the clutch block 45 will leave the clutch groove 441 after a certain period of time. If the user needs to unlock the lock through the front handle, the identity needs to be re-identified.

[0045] In the deadbolt mode: the clutch block 45 disengages from the clutch slot 441, and the fingerprint recognition module 21 and the password recognition module stop working, meaning that the movement of the electronic clutch mechanism 6 cannot be controlled; the lock can only be opened with a key.

[0046] Normally open mode: Clutch block 45 is always inserted into clutch slot 441, and the user can turn the front handle to unlock at any time.
