[0042] The hand-automatic integrated door and window lock of the utility model has the following steps when used in the electric state:

[0043] 1. Power supply: the power supply unit 10 provides electric energy for the electric drive mechanism.

[0044] 2. Motor starting: the motor 6 starts after receiving the electric energy, converts the electric energy into mechanical energy, and starts rotating.

[0045] 3. Power transmission: the output end of the motor is engaged with the electric gear set 7 through the driving gear 61, and the rotating power is transmitted to the electric gear set.

[0046] ​4. Gear set rotation: The electric gear set transmits power to the input gear disc of the clutch mechanism 5, the input gear disc 51 rotates, in turn driving the push arm 511 to rotate, which pushes the clamping block 55. The clamping block 55 will overcome the magnetic force of the magnet and enter the arc-shaped groove 521 under the action of centrifugal force along the inward converging push arm 511, allowing the clamping block 55 to be partially contained in the arc-shaped groove 521 and partially extend out of the arc-shaped groove 521, and abutting against the push arm 511, receiving the tangential force and driving the output gear disc 52 to rotate. The output gear disc 52 transmits power to the transmission gear set 8, which in turn drives the control gear 43 to rotate.

[0047] 5. Control shaft rotation: The control gear 43 on the control shaft 4 is linked with the electric drive mechanism, and the control shaft 4 rotates with the handle 3.

[0048] 6. Lock tongue action: The rotation of the control shaft 4 drives the lock tongue 2 to switch between unlocked and locked states through the rack 21 and the lock tongue gear 41.

[0049] 7. Position detection: The position sensor 9 monitors the position of the lock tongue in real time and feeds back the state information to the control system, so that the user or intelligent system can understand the current state of the lock.

[0050] 8. Complete operation: The lock tongue reaches the predetermined position (unlocked or locked), and the motor stops working, completing the electric operation.

[0051] When an emergency such as motor damage occurs, the hand-operated door and window lock of the utility model can be manually unlocked or locked, and the specific steps are as follows:

[0052] 1. Handle operation: The user directly holds the handle 3, preparing to operate the lock by hand.

[0053] 2. Drive shaft rotation: The user rotates the handle 3, and the rotation is transmitted to the control shaft 4 through the drive shaft 31.

[0054] 3. Clutch mechanism separation: During manual operation, the clamping block 55 in the clutch structure has two situations. One is that the clamping block 55 does not stay in the arc-shaped groove 521, at which time the input gear disc 51 and the output gear disc 52 are not linked, and the output gear disc 52 idles when unlocking or locking, making it convenient to unlock or lock. The second is that the door and window lock is suddenly powered off during use, and the input gear disc 51 and the output gear disc 52 are still linked, at which time the clamping block 55 is still limited in the arc-shaped groove 521. Only by rotating the handle 3, the output gear disc 52 rotates, and the clamping block 55 is separated from the limiting of the push arm 511. During the rotation of the output gear disc 52, the clamping block 55 leaves the arc-shaped groove 521, and the output gear disc 52 idles. The clutch mechanism 5 is automatically separated from the electric drive mechanism, ensuring that the motor 6 is not affected and avoiding load.

[0055] 4. The action of the bolt: the rotation of the control shaft 4 drives the bolt 2 through the rack 21 and the bolt gear 41, switching it between the unlocked and locked states.

[0056] 5. The upper and lower limit parts interaction: when the bolt 2 reaches the unlocked or locked state, the handle 3 is limited by the corresponding upper limit part 11 or lower limit part 12, preventing the handle 3 from rotating excessively.

[0057] 6. Position feedback: the handle 3 stops under the block of the upper limit part 11 or lower limit part 12, giving the user intuitive feedback that the bolt 2 has reached the unlocked or locked position.

[0058] 7. Complete operation: the bolt 2 reaches the predetermined position, the manual operation is completed, at this time the user can open or close the door and window.
