While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

As shown in fig. 1, the electric window shade control device of the present invention, as shown in fig. 1, is used in combination with a connector 200 located above, the control device 100 is connected to the connector 200, the connector 200 is sleeved on a roman rod, the lower part of the control device 100 is connected to a window shade, and the control device 100 can horizontally move along the roman rod, thereby pulling the window shade to open or close along the roman rod. Of course, the control device 100 may be connected to other connecting devices, which may connect the control device to the existing curtain rail and move horizontally along the rail, and the control device 100 itself is connected to the curtain to drive the curtain to open and close. The curtain and the curtain rail are the existing curtain and rail, so that the curtain can be automatically opened and closed only by slightly modifying the existing curtain and rail.

The control device comprises a shell 10 and a rolling wheel arranged in the shell 10, wherein the rolling wheel comprises a driving wheel 1 and a driven wheel 2, the driving wheel 1 and the driven wheel 2 are arranged on a support 3 at the same height, and a lifting motor 20 for driving the support 3 to move up and down and a driving motor 30 for driving the driving wheel to rotate are also arranged in the shell 10. The driving motor is also arranged on the bracket 3, and the lifting motor 20 can drive the bracket 3 to move up and down, so as to drive the driving wheel 1, the driven wheel 2 and the driving motor 30 on the bracket 3 to move up and down together. The driven wheel 2 and the driving wheel 1 are arranged at the top of the bracket 3, are axially and transversely supported on the bracket 3, can rotate around respective axial directions of the driven wheel 1 and the driven wheel 2, and are axially arranged in the same direction, for example, as shown in fig. 1 and 2, the axial directions of the driving wheel 1 and the driven wheel 2 are perpendicular to the extending direction of the curtain track, i.e. the moving direction of the control device, and the axial directions of the driving wheel 1 and the driven wheel 2 are parallel and are arranged in parallel at intervals along the extending direction of the curtain track, i.e. the moving direction of the control device; or the axial directions of the driving wheel 1 and the driven wheel 2 are perpendicular to the extending direction of the curtain track, namely the moving direction of the control device, the two wheels are arranged side by side along the width direction of the curtain track, and the axial directions of the driving wheel 1 and the driven wheel 2 can be staggered and arranged side by side or overlapped in the moving direction of the control device. An opening 40 is arranged above the shell 10, the driving wheel 1 and the driven wheel 2 are exposed, the bracket 3 can move upwards under the driving of the lifting motor 20, and then the driving wheel 1 and the driven wheel 2 move upwards from the opening 40 of the shell 10 and are attached to the rail, and then under the driving of the driving motor 30, the driving wheel 1 rotates, so that the whole control device can move along the curtain rail, and meanwhile, the driving wheel 1 and the control device 100 move horizontally along the rail to drive the driven wheel 2 to rotate along the rail. The axial directions of the driving wheel 1 and the driven wheel 2 are vertical to the vertical movement direction of the bracket 3 and the extending direction of the curtain rail, namely the movement direction of the control device. In order to ensure that the driving wheel 1 can synchronously drive the driven wheel 2 to rotate when driving the control device 100 to move, the diameters of the driving wheel 1 and the driven wheel should be the same. The shell 10 of the control device is also provided with a detachable hook 300, the hook 300 is used for connecting with the connecting piece 200, and the detachable hook 300 can be used for connecting pieces 200 with different sizes and dimensions.

As shown in fig. 2 and 3, the lifting motor 20 is fixedly disposed in the housing 10, and a battery 50 and a control circuit board 60 are further disposed in the housing 10 for providing power to the lifting motor 20 and the driving motor 30. The output shaft of the lifting motor 20 is connected to a vertically arranged threaded rod 201, a nut block 202 matched with the threaded rod 201 is sleeved on the outer side of the threaded rod 201, and the nut block 202 is fixedly connected to the support 3. The lifting motor 20 drives the threaded rod 201 to rotate around the vertical axial direction of the threaded rod, so that the nut block 202 and the support 3 can be driven to move up and down along the threaded rod 201. Therefore, the lifting motor 20 can drive the bracket 3 to move up and down, and of course, those skilled in the art will appreciate that other transmission mechanisms may be provided between the lifting motor 20 and the driving bracket 3 to enable the lifting motor 20 to drive the bracket 3 to move up and down.

A transmission mechanism is arranged between the output shaft of the driving motor 30 and the driving wheel 1, and the transmission mechanism, as shown in fig. 4, includes a plurality of gears engaged with each other, wherein the last gear 4 is connected to the driving wheel 1, that is, the last gear is an output end of the transmission mechanism, and the output end is connected to the driving wheel. The clutch device is further arranged in the driving wheel 1, the final-stage gear 4 is connected to the driving wheel 1 through the clutch device, when the final-stage gear 4 drives the driving wheel 1 to rotate, the clutch device is always kept in a combined state, and when the final-stage gear 4 does not rotate and the driving wheel 1 automatically rotates, the clutch device can be kept in a separated state, namely the driving rotation on one side of the driving wheel 1 cannot be transmitted to the final-stage gear 4. Furthermore, when the motor drives the driving wheel to rotate, the driving wheel can move along the track under the driving of the motor, and then the whole control device can move along the curtain track to drive the opening and closing of the curtain, when the motor does not operate, and when the curtain is pulled manually, the driving wheel 1 and the driven wheel 2 can be driven by the force of manual pulling to move along the curtain track, and at the moment, the existence of the clutch device can ensure that the driving wheel 1 can rotate under the action of external force without influencing the structures of a driving motor and the like below, because the rotation of the driving wheel 1 at the moment can not be transmitted to a transmission mechanism and the driving motor below, the manual pulling of the curtain is further realized, and the motor is prevented from being damaged due to the manual pulling of the curtain. The clutch device realizes the transmission from the transmission mechanism to the driving wheel 1 on the premise of ensuring the connection between the transmission mechanism and the driving wheel, and prevents the driving wheel 1 from transmitting to the transmission mechanism, thereby realizing two functions of manually pulling the curtain and electrically driving the curtain. This clutch can locate in action wheel 1, also can locate the outside, and its output and the action wheel that is used for connecting drive mechanism to guarantee that driving motor's output can transmit to the action wheel, but under the circumstances that driving motor stopped, the rotation of action wheel can not transmit to drive mechanism and action wheel.

As shown in fig. 5, 6 and 7, the driving wheel 1 includes a housing 11 and an inner housing 12, the housing 11 and the inner housing 12 are coaxially disposed, the axial directions of the housing 11 and the inner housing 12 are horizontally disposed, and the housing 11 and the inner housing 12 are fixedly connected in an internally-externally sleeved manner and can synchronously rotate. One end of the inner shell 12 is provided with a shaft 13, one end of the shaft 13 is exposed out of the shell 11 and is provided with a bearing 15 connected to the bracket 3, so that the driving wheel 1 can rotate around the shaft 13. The other end of the inner housing 12 is provided with a cavity 14 extending axially along the inner housing, and the other end of the shaft 13 is located in the cavity 14.

The clutch device comprises two steel balls 51 arranged in the cavity 14, a retainer ring 52 for sealing the steel balls 51 in the cavity 14, and a central opening of the retainer ring 52, wherein a first end of a cam 53 is positioned in the cavity 14 and matched with the steel balls 51, and a second end of the cam 53 extends out of the outer side of the retainer ring 52 through the central opening of the retainer ring 52 and is connected with the final gear 4 through tooth profiles.

As shown in fig. 6, the inner circumferential wall of the cavity 14 of the inner shell 12 is provided with two concave holes 141 matching with the steel balls 51, and the concave holes 141 are symmetrically arranged. The cam 53 is provided at a first end thereof with a projection 531 extending in a radial direction of the drive wheel 1, the projection 531 having a thickness matching a thickness of the cavity 14 and dividing the cavity 14 into a first portion 142 and a second portion 143, and each portion is provided therein with a steel ball 51. The rotation of cam 53 can drive steel ball 51 and rotate in cavity 14 to when cam 53 rotated to the shrinkage pool 141, two sets of steel balls 51 and shrinkage pool 141 cooperate and block cam 53 respectively from two directions, make inner shell 12 and cam 53 block each other and be connected, and then the rotation of cam 53 can drive inner shell 12 and casing 11 simultaneously, and cam 53 rotates with the action wheel synchronous promptly. Therefore, transmission from the drive motor to the transmission mechanism to the drive pulley 1 is realized. And when the driving motor loses power, namely the final gear of the transmission mechanism does not rotate, the external force drives the driving wheel 1 to rotate, at the moment, the shell 11 and the inner shell 12 rotate, and due to the rotation of the inner shell 12, the steel balls 51 can be separated from the concave holes 141, and then fall and be positioned in the cavity 14, and the static state of the cam 53 cannot be influenced, so that the rotation of the driving wheel 1 is manually driven, and the separation state of the driving wheel 1 to the transmission between the transmission mechanisms is realized. As can be understood by those skilled in the art, the clutch device and the mechanism of the driving wheel 1 can also refer to the structure in the Chinese patent ZL 202023309384.5. Only one-way rotation transmission from the transmission mechanism to the driving wheel 1 is realized, and rotation transmission from the separation driving wheel 1 to the transmission mechanism is realized. A large bearing 54 is also provided between the axially outer side of the retainer ring 52 and the inner shell 12 to enable the inner shell 12 and housing 11 to rotate relative to the inner structure. The cam 53 has a protrusion 531 in a shuttle shape, i.e., thick in the middle and narrow at both ends, and is axially symmetric. Therefore, during the rotation of the cam 53, the steel balls 51 can be driven toward both ends and slid into the concave hole 141 of the inner peripheral wall of the cavity 14 of the inner housing 12. For more smooth movement, the portion of the shaft 13 located in the cavity 14 is further provided with a protruding shaft 121, and the center of the cam 53 opposite to the protruding shaft 121 is provided with a groove 535, so that the two are mutually matched, and the cam 53 is driven by the final gear 4 to rotate around the axial direction, and thus moves more smoothly without shaking along the radial direction.

As shown in fig. 4, the driven wheel 2 is provided with a magnet, the housing 10 is further provided with a circuit board 70 matching with the magnet, the circuit board 70 is provided with a hall element, and the hall element is matched with the magnet, so that the specific stroke and position of the driven wheel, i.e., the control device, can be calculated according to a rotation signal generated by the hall element, and whether the driven wheel slips or not can be judged according to the presence or absence of the rotation signal. Since the driven wheel 2 only rotates along with the horizontal movement of the control device, once the driven wheel slips or is blocked, namely the rotation signal of the hall element stops immediately, a signal can be generated to stop the driving motor, and the accurate stroke position can be calculated. Compared with the original scheme that only one rotating wheel is arranged, the Hall element also detects the rotation of the rotating wheel, when the control device moves to the end of the track and meets a resistance, the rotating wheel does not move along the track any more, only idles in situ, and at the moment, the Hall element still has a signal and cannot judge whether the resistance is met or not. The judgment of the encountered resistance is that the encountered resistance is judged according to the increase of the friction force of the rotating wheel and the increase of the current of the driving motor, and the judgment that the resistance is encountered is carried out only after the current of the driving motor is increased, and the stroke point is recorded at the moment, the judgment that the control device has moved in place is carried out, but the rotating wheel idles for a period of time in the friction force increasing process, so the calculated stroke position is not too accurate; and if the friction force is not large, the current of the driving motor is not large, the control system can carry out misjudgment and continue to operate without stopping, and misjudgment of resistance and in-place stroke movement is easily caused.

Compare the scheme that only has a rotation wheel, the scheme of two rotation wheels of this embodiment, in case controlling means meets and hinders the back from the driving wheel and can stop, promptly also the hall element can export promptly and meet and hinder the signal, so not only the stroke judgement is accurate, moreover, the controlling means that two wheels set up side by side is more steady reliable along orbital motion. And those skilled in the art can understand that the cooperation of the hall element and the magnet can be replaced by other devices, that is, as long as the driven wheel is provided with a stroke detection device.

The control device is provided with a driving wheel 1 driven by a driving motor to rotate and a driven wheel 2 driven by the control device to move, and the driven wheel is provided with a magnet matched with the Hall element, so that the control device not only can move more stably, but also can be quickly stopped, and is accurate in judgment and stroke calculation. As shown in fig. 8, the control flow of the motorized window treatment control device is substantially as follows:

the electric curtain control device is arranged on the curtain rail, and the curtain blades or the curtain cloth are connected below the electric curtain control device.

The lifting driving wheel and the driven wheel enable the two wheels to press the curtain rail tightly, and the system is in standby and waits for signals. Specifically, promote the action wheel and rely on elevator motor to go on from the driving wheel, firstly, elevator motor starts after the start, elevator motor's start-up drives whole support 3 and upwards moves along shell 1, and then make action wheel 1 and follow driving wheel 2 from upwards propping up the curtain track down, support 3 rises to the back of targetting in place, action wheel 1 and follow driving wheel 2 support the curtain track and the current of elevator motor risees after being blocked, judge whether elevator motor's current exceeds the default, if exceed the default, elevator motor stop motion, and keep in the high position, guarantee that action wheel 1 and follow driving wheel 2 paste the curtain track tightly, then whole controlling means is in standby state, and wait for the received signal, if do not exceed, then continue to improve the current until exceeding the default.

If the starting signal is received, the starting program is operated. Specifically, in a standby state, a wireless remote control signaler can send a starting instruction to the control device, and after receiving a starting signal, a starting program is operated, wherein the specific starting program comprises the steps of generating a driving signal to drive a driving wheel to roll along a curtain rail and drive a driven wheel to move in the same direction, detecting a stroke signal on the driven wheel, and calculating the stroke of the control device according to the stroke signal.

The method comprises the following steps that a driving signal is generated to drive a driving motor to drive a driving wheel 1 to rotate, then the whole control device moves along a curtain rail, and the horizontal movement of the control device drives a driven wheel 2 to move. And detecting a stroke signal on the driven wheel, wherein the stroke signal is a rotation signal generated by a Hall element corresponding to the driven wheel. The control device also needs to judge whether a rotation signal of the driven wheel 2 exists, if the rotation signal of the hall element does not exist at the moment and a driving signal exists, the driving wheel 1 and the driven wheel 2 are judged not to move along the rail, the slipping is judged, the driving signal needs to be stopped at the moment, the lifting motor is enabled to continue to be started, the driving wheel 1 and the driven wheel 2 are driven to continue to move upwards to press the curtain rail, and then the curtain rail returns to a standby state and waits for receiving the signal.

If the rotation signal of the Hall element exists at the moment, the starting program is continuously operated, the rotation signal of the Hall element is continuously detected, the stroke of the control device can be calculated according to the stroke signal, if the stroke calculated by the rotation signal of the Hall element on the driven wheel is monitored to reach the preset stroke, the curtain is moved in place, the driving signal stops, the driving motor stops operating, the control device moves in place, the curtain returns to the standby state, and the signal is waited. The preset stroke may be the length of the whole curtain, or a half length, etc., for example, the curtain is opened in half, and the user sets the preset stroke according to the requirement.

If the rotation signal of the Hall element on the driven wheel is monitored to stop and the stroke does not reach the end point, namely the calculated stroke does not reach the preset stroke, judging that the control device is in a resistance state, stopping the driving signal, stopping the driving motor, returning to a standby state, and waiting for the signal, namely waiting for a next step instruction; and the current stroke is recorded, so that the stroke can be conveniently accumulated and calculated after subsequent secondary movement, a starting signal of continuous movement or reverse movement can be received subsequently, and at the moment, the recorded stroke position can be used as an initial position for calculation, and whether the continuous movement or the reverse movement reaches a terminal point is further judged.

If the rotation signal of the Hall element is not stopped, but the control device receives a stop signal sent by the wireless remote control device, the driving signal is stopped, the driving motor stops running, and the control device returns to a standby state to wait for a signal. And the current stroke needs to be recorded, so that accumulated calculation of the stroke after subsequent secondary movement is facilitated, a starting signal of continuous movement or reverse movement can be received subsequently, and at the moment, the recorded stroke position can be used as an initial position for calculation, and whether the continuous movement or the reverse movement reaches a terminal point is judged.

If the curtain is manually pulled in a standby state, the driving motor does not move, namely the driving signal does not exist, the driven wheel can also generate a rotating signal of the Hall element, namely a stroke signal, whether the curtain is manually started or not is judged, and if the curtain is manually started, the starting program is operated to automatically pull the curtain. Specifically, the determination as to whether the manual start is performed may be to calculate the stroke of the control device according to the stroke signal or to determine the duration of the stroke signal, and if the duration of the stroke signal exceeds a preset time or the obtained stroke exceeds a preset start stroke, the manual start is determined to be true. The operation starting program comprises the steps of generating a driving signal to drive the driving wheel to roll along the curtain rail and drive the driven wheel to move in the same direction; and detecting a stroke signal on the driven wheel, and obtaining the stroke of the control device according to the stroke signal to realize the automatic and manual starting function of manually pulling the curtain. If the curtain is blown by wind only or is pulled unintentionally, and the duration of the travel signal exceeds a preset time or the obtained travel exceeds a preset starting travel, it is determined that the curtain is not started manually. After the starting program is operated, the monitoring of the rotation signal of the Hall element on the driven wheel is carried out as the subsequent steps of receiving the wireless remote control signal and sending the starting signal to drive the driving motor to move.

As shown in fig. 9, another embodiment of the control method of the motorized window treatment control apparatus according to the present invention is similar to the other parts of fig. 8 except that only the stroke signal of the driven wheel is detected, and the stroke of the specific control apparatus is not calculated according to the stroke signal.

Thus, if a start signal is received, a start-up procedure is run. Specifically, in a standby state, a wireless remote control signaler can send a starting instruction to a control device, and after receiving a starting signal, a starting program is operated, wherein the specific starting program comprises the steps of generating a driving signal to drive a driving wheel to roll along a curtain rail and drive a driven wheel to move in the same direction, and detecting a stroke signal on the driven wheel.

The method comprises the following steps that a driving signal is generated to drive a driving motor to drive a driving wheel 1 to rotate, then the whole control device moves along a curtain rail, and the horizontal movement of the control device drives a driven wheel 2 to move. And detecting a stroke signal on the driven wheel, wherein the stroke signal is a rotation signal generated by a Hall element corresponding to the driven wheel. The control device also needs to judge whether the rotation signal exists, if the rotation signal of the hall element does not exist at the moment and the driving signal exists, the driving wheel 1 and the driven wheel 2 are judged not to move along the track, the slipping is judged, the driving signal needs to be stopped at the moment, so that the lifting motor is continuously started, the driving wheel 1 and the driven wheel 2 are further driven to continuously move upwards to press the curtain track, and then the curtain track is returned to the standby state and waits for receiving the signal.

If the rotation signal of the Hall element exists at the moment, the starting program is continuously operated to continuously detect the rotation signal of the Hall element, if the rotation signal of the Hall element on the driven wheel is monitored to stop, the travel is judged to be in place, the driving signal stops, the driving motor stops operating, and the driven wheel returns to a standby state to wait for the signal, namely waiting for the next step of instruction; the subsequent motion may be initiated by a further or reverse motion. This solution makes it possible to control the movement of the control device without stroke, but only by the presence or absence of a stroke signal on the driven wheel.

If the curtain is manually pulled in a standby state, the driving motor does not move, namely the driving signal does not exist, the driven wheel can also generate a rotating signal of the Hall element, namely a stroke signal, whether the curtain is manually started or not is judged, and if the curtain is manually started, the starting program is operated to automatically pull the curtain. Specifically, the determination as to whether the manual start is performed may be to calculate the stroke of the control device according to the stroke signal or to determine the duration of the stroke signal, and if the duration of the stroke signal exceeds a preset time or the obtained stroke exceeds a preset start stroke, the manual start is determined to be true. The operation starting program comprises the steps of generating a driving signal to drive the driving wheel to roll along the curtain rail and drive the driven wheel to move in the same direction; and a travel signal on the driven wheel is detected, so that the automatic and manual starting function of manually pulling the curtain is realized. If the curtain is blown by wind only or is pulled unintentionally, and the duration of the travel signal exceeds a preset time or the obtained travel exceeds a preset starting travel, it is determined that the curtain is not started manually. After the starting program is operated, the monitoring of the rotation signal on the driven wheel is carried out as the subsequent steps of receiving the wireless remote control signal and sending the starting signal to drive the driving motor to move. That is, in this scheme, the stroke is calculated according to the stroke signal, and is only used for judging whether the curtain is pulled manually, but not for judging whether the stroke is in place. As soon as the control device is blocked, the control device naturally stops.

The electric curtain control device and the control method thereof can ensure the automatic and stable movement of the control device along the track, can realize the functions of automatically opening and closing the curtain and manually pulling and starting the automatically pulled curtain, judge the stroke accurately, ensure the automatic pulled curtain to be in place, prevent the control device from being pulled out of place due to the fact that the movement of the control device is not easy to slip, and provide better use effect and more accurate control function.
