[0020] The following is a detailed description of the embodiments of the technical solution of the present invention in conjunction with the accompanying drawings. The following embodiments are only used to illustrate more clearly

[0021] The technical solution of the present invention is therefore only used as an example and cannot be used to limit the protection scope of the present invention.

[0022] like Figure 1-4 As shown in the figure, a hidden manual-automatic intelligent electric lock box includes an electric lock box arranged in a window frame for opening and closing the window, and the electric lock box includes a housing 1, and a rotating power structure for providing power for opening and closing the window is arranged in the housing 1.

[0023] The rotating power structure is meshedly connected with a manual automatic switching transmission structure, and the manual automatic switching transmission structure includes a two-stage reduction gear set and a gear A2, the two-stage reduction gear set includes a large gear C3 and a small gear C4 coaxially connected, one end of a swing connecting rod 5 is coaxially connected to the outside of the small gear C4, and the other end of the swing connecting rod 5 is coaxially connected to a swing gear 6, the axis of the swing gear 6 is parallel to the axis of the small gear C4, and the axis of the swing gear 6 is perpendicular to the length direction of the swing connecting rod 5; the small gear C4 is meshedly connected with the swing gear 6, and the swing gear 6 is meshedly connected with the gear A2; the gear A2 and the housing 1 corresponding to the left and right sides are provided with a coaxial handle rotating hole 7, and a rotating handle is placed in the handle rotating hole 7; the axis of the two-stage reduction gear set is parallel to the axis of the gear A4, and the axis of the swing gear 6 is perpendicular to the length direction of the swing connecting rod 5; the pinion gear C4 is meshedly connected with the swing gear 6, and the swing gear 6 is meshedly connected with the gear A2; the gear A2 and the housing 1 corresponding to the left and right sides are provided with a coaxial handle rotating hole 7, and a rotating handle is placed in the handle rotating hole 7; the axis of the two-stage reduction gear set is parallel to the axis of the gear A4, and the rotation ... A boss 8 for blocking the swinging motion of the swing connecting rod 5 is arranged on the inner side of the housing 1 between the axis lines of the two axes; a transmission rod 9 for driving the door and window movement is slidably connected to the top of the housing 1 along the length direction of the housing 1, and a rack 10 meshing with the gear A2 is fixedly connected to the lower surface of the transmission rod 9 corresponding to the gear A2; the rotating power structure is a forward and reverse power structure; the rotating power structure is connected to the controller. Among them, the function of the boss 8 is that after the swing connecting rod 5 rotates to the boss 8, the boss 8 limits the circular motion of the swing connecting rod 5, and the swing connecting rod 5 stops moving, and at the same time, the swing gear 6 and the gear A are engaged to realize the transmission of torque. Among them, the gear A2 cooperates with the rack 10 to realize the change of the circular motion of the gear A2 into the linear motion of the rack 10, and the rack 10 is riveted and fixed to the transmission rod 9 to realize the linear motion of the transmission rod 9 of the lock box.

[0024] As a preferred embodiment, the lower surface of the transmission rod 9 is also fixedly connected to a stopper 11, and a position sensing structure is fixedly arranged at the top of the housing 1 corresponding to the stopper 11. The position sensing structure includes a connecting rod parallel to the transmission rod, and a position sensor is arranged on the upper surface of the connecting rod. The position sensors correspond to the suspended position sensing point, the horizontal open position sensing point, and the locked position sensing point in sequence; the position sensing structure is connected to the controller. When the stopper 11 moves to the corresponding position, the corresponding sensing point will receive the blocking of the stopper 11, and feed back the sensed information to the controller in the form of a signal. The controller controls the driving motor 12 to stop and rotate in the opposite direction for a certain angle, so as to realize the disengagement of the swing gear 6 and the gear A2. After the disengagement, it enters the manual state. A person can rotate the handle by holding it, so that the gear A2 drives the rack 10, and then drives the transmission rod 9 to move, so as to realize the movement of the door and window.

[0025] As a preferred embodiment, the rotating power structure includes a driving motor 12 fixed in the casing 1 and arranged along the length direction of the casing 1, the driving motor 12 is connected to a reducer, the output shaft of the reducer is coaxially connected to a worm 13 rotatably arranged in the casing 1, the worm 13 is arranged along the length direction of the casing 1, a turbine 14 is rotatably arranged in the casing 1, the turbine 14 is coaxially fixed with a gear plate A15, the worm 13 is meshingly connected with the turbine 14, and a first-stage reduction gear set is rotatably arranged in the casing 1 behind the gear plate A15; the first-stage reduction gear set includes a large gear B16 and a small gear B17 coaxially connected, and the gear plate A15 is meshingly connected with the large gear B16; the driving motor is connected to the controller.

[0026] As a preferred implementation, the small gear B17 is meshedly connected to the large gear C3 of the manual-automatic switching transmission structure.

[0027] As a preferred embodiment, the drive motor 12, reducer, worm 13, primary reduction gear set, secondary reduction gear set and gear A2 are arranged in sequence from front to back in the casing 1 along the length direction of the casing 1.

[0028] As a preferred embodiment, the three position sensing points of the position sensor are, from front to back, a suspended position sensing point, a horizontally opened position sensing point, and a locked position sensing point, wherein the suspended position sensing point is the position on the connecting rod corresponding to the block when the transmission rod 9 moves to the suspended state so that the window is in the horizontally opened state, wherein the horizontally opened position sensing point is the position on the connecting rod corresponding to the block when the transmission rod 9 moves to the horizontally opened state so that the window is in the locked state, wherein the locked position sensing point is the position on the connecting rod corresponding to the block when the transmission rod 9 moves to the locked state. A block 11 is fixed on the transmission rod 9, and the block 11 performs linear motion on the position sensor. There are three sensing points for the tube on the position sensor, and the sensing points are divided into a suspended position sensing point, a flat open position sensing point, and a locked position sensing point. When the transmission rod 9 drives the block 11 to perform linear motion, and the outside world gives a window opening, locking or suspended signal, the electric lock box moves. When the block 11 contacts the corresponding sensing point (window opening, locking, suspended), the movement stops to achieve the required opening, locking and other states, and the signal is transmitted to the drive motor 12. The drive motor 12 reverses for a certain period of time, and the gear A2 disengages from the swing gear 6 to achieve manual opening.

[0029] As a preferred embodiment, the tail end of the swing connecting rod 5 is connected to the swing gear 6 through the swing sleeve 18, and a restoring spring 19 is sleeved on the swing sleeve 18 between the swing connecting rod 5 and the swing gear 6. The swing gear 6 has two degrees of freedom, one for self-rotation and the other for driving the swing connecting rod 5 to perform circular motion. When the driving motor 12 rotates, the swing gear 6, driven by the swing connecting rod 5, performs circular motion around the large gear C3 and the small gear C4, and performs self-rotation motion at the same time. When it moves to the position of the boss 8, due to the position restriction of the boss 8, the degree of freedom of the circular motion of the swing gear 6 disappears, and it only rotates and engages with the gear A2 to achieve the transmission of torque. When it moves for a certain time, the driving motor 12 reverses, and the swing gear 6 drives the swing connecting rod 5 to disengage from the boss 8, that is, disengage from the gear A2 and does not engage, so as to achieve the disengaged state of the gear, and realize the manual opening of the lock box through the square hole on the gear A2, so as to realize manual opening.

[0030] The hidden manual-automatic intelligent electric lock box of the present invention is used. When the door and window need to be opened in the locked state, the driving motor 12 is started by the controller, the driving motor 12 rotates, and the worm 13 is driven to rotate through the reducer, the worm 13 is meshed with the turbine 14, the turbine 14 rotates coaxially with the gear plate A15, the gear plate A15 is meshed and connected with the large gear B, the large gear B16 is coaxially connected with the small gear B17, the rotation of the small gear B17 drives the large gear C3 to rotate, the large gear C3 rotates coaxially with the small gear C4, the small gear C4 rotates coaxially with the swing connecting rod 5, and the swinging motion of the swing connecting rod 5 is realized. At the same time, the small gear C is meshed with the swing gear 6. When the swing connecting rod 5 swings to make the swing gear 6 mesh with the gear A2, the gear and rack motion of the gear A2 and the rack 10 can drive the transmission rod 9 to move and open the window; similarly, when the door and window are in the open state, the door and window are locked by reversing. When the doors and windows are in the locked state / open state, they need to be started to the manual state. The corresponding sensing points among the suspended position sensing point, the flat open position sensing point and the locked position sensing point of the position sensor will be blocked by the block 11, and will send a signal to the controller. The controller will start the drive motor to rotate in the reverse direction, so that the swing connecting rod 5 will drive the swing gear 6 to swing in the reverse direction, and the gear A2 and the swing gear 6 can be disengaged. After disengagement, the electric lock box enters the manual state, and the brake handle can adjust the doors and windows.
