Fig. 3 is a schematic structural diagram of a curtain motor according to an embodiment of the present invention, where the curtain motor 15 includes: the main machine hanging buckle comprises a shell (not shown), a driving wheel 1511, a direct current motor 1512, a driven wheel 1513, a hanging buckle push rod 1521, a screw rod 1522, a stepping motor 1523, a tensioning mechanism support 1524, a controller 153 (not shown), a main machine hanging buckle 154 and a Hall sensor 155.
The curtain motor 15 is mounted on the curtain through the host hanging buckle 154, specifically, one end of the host hanging buckle 154 extends out of the housing and is connected with a curtain hook on the curtain rail, so that the curtain motor 15 is mounted on the curtain hook. The other end of the host hanging buckle 154 is fixedly connected with the hanging buckle push rod 1521, and specifically, the other end of the host hanging buckle may be in threaded connection.
The drive wheel 1511, the dc motor 1512, and the driven wheel 1513 may collectively constitute the drive apparatus 151. A part of the driving wheel 1511 extends out of the housing and abuts against the curtain rail, and the driving wheel 1511 is connected with the dc motor 1512. The dc motor 1512 may include a motor and a reduction box, and a clutch may be disposed on the driving wheel 1511, and the driving wheel 1511 is connected to the dc motor 1512 through the clutch and the reduction box. The direct current motor 1512 is disposed in the housing and in signal connection with the controller 153, and the direct current motor 1512 is configured to receive a control signal sent by the controller 153 and drive the driving wheel 1511 to rotate according to the control signal. The driving wheel 1511 is used to drive the curtain motor 15 to move in the horizontal direction during the rotation process, and at the same time, the driven wheel 1513 abutting against the track of the curtain is driven by the friction force between the driven wheel 1513 and the track to start to rotate. The driven wheel 1513 is provided with at least one magnet, the driven wheel 1513 drives the at least one magnet to rotate when rotating, so as to drive the magnetic field generated by the magnet to rotate, the hall sensor 155 is located in the magnetic field, and can detect the magnetic field signal generated when the magnetic field rotates and output a square wave signal according to the detected magnetic field signal. The square wave signal may be used to indicate whether the driven wheel 1513 is rotating, the number of revolutions, etc.

The hall sensor 155 is a bipolar latch type hall sensor, which is disposed on the PCB of the curtain motor 15 and below the driven wheel 1513, and can detect a magnetic field signal generated when the magnet rotates. When the driven wheel 1513 rotates, the bipolar latching type hall sensor outputs a low level when the N pole of the magnet passes through, and outputs a high level when the S pole of the magnet passes through; or when the N pole of the magnet passes through, the bipolar latching type Hall sensor outputs a high level, and when the S pole of the magnet passes through, the bipolar latching type Hall sensor outputs a low level.
In this embodiment, when the driving wheel 1511 and the driven wheel 1513 normally rotate, the controller 153 outputs a control signal and the hall sensor 155 outputs a square wave signal. If the control signal output by the controller 153 is not interrupted and the obtained square wave signal is abnormal, it may be determined that a slip phenomenon occurs between the driving wheel 1511 and the track of the window curtain. Wherein the square wave signal anomalies comprise: the square wave signal is interrupted, the square wave signal continuously outputs a high level or a low level, and the like. The control signal is not interrupted, that the direct current motor 1512 is continuously driving the driving wheel 1511 to rotate, and that the square wave signal is abnormal indicates that the driven wheel 1513 does not rotate, at this time, it can be determined that the driving wheel 1511 slips.
When the slipping phenomenon is detected, the direct current motor 1512 can be controlled to stop driving, and a clasping function can also be started, wherein the clasping function is used for clasping the driving wheel 1511 with the track of the curtain, so that the slipping phenomenon is avoided.
It should be noted that, in addition to the arrangement of the driving wheel 1511 and the driven wheel 1513 as shown in fig. 3, the order of the driving wheel 1511 and the driven wheel 1513 may be changed, for example, the driving wheel 1511 is arranged on the left side, and the driven wheel 1513 is arranged on the right side. In addition, the diameter of the driving wheel 1511 and the driven wheel 1513 may be the same or different, and the driving wheel 1511 and the driven wheel 1513 may be proportionate in size when different, for example, the driven wheel 1513 is half as large as the driving wheel 1511.
In this embodiment, the driving wheel 1511 and the driven wheel 1513 are arranged to drive the curtain motor 15 to move horizontally, so that the curtain motor 15 can operate more stably than the driving wheel 1511.
The buckle push rod 1521, the screw rod 1522, the stepping motor 1523 and the tensioning mechanism bracket 1524 may jointly form a tensioning mechanism 152 (not shown).

It should be noted that the screw rod 1522 and the hanging buckle push rod 1521 can be movably connected in other manners besides being connected in a threaded fit manner. The other end of the screw rod 1522 is fixedly connected with the bottom of the tensioning mechanism bracket 1524. The stepping motor 1523 is fixed to the lower end of the tensioning mechanism bracket 1524.

The working principle is as follows: the stepping motor 1523 is configured to receive a control signal sent by the controller 153, and rotate counterclockwise according to the control signal to drive the screw rod 1522 to rotate clockwise, or rotate clockwise according to the control signal to drive the screw rod 1522 to rotate counterclockwise; the screw rod 1522 is used for driving the hanging buckle push rod 1521 to move downwards when the screw rod 1522 rotates clockwise, or driving the hanging buckle push rod 1521 to move upwards when the screw rod 1521 rotates anticlockwise; when the hanging buckle push rod 1521 moves downwards, the curtain motor 15 moves upwards to enable the driving wheel 1511 to clasp the track of the curtain; when the hanging buckle push rod 1521 moves upwards, the curtain motor 15 moves downwards, so that the driving wheel 1511 leaves the curtain track.
When the curtain motor 15 moves in the vertical direction, the curtain rail and the curtain hook are fixed, the main unit hanging buckle 154 and the hanging buckle push rod 1521 can be regarded as a whole, for example, it can be regarded as a nut, and the screw rod 1522 fixed to the tensioning mechanism bracket 1524 can be regarded as a screw. When the screw rod 1522 rotates clockwise or counterclockwise when being fixed, the nut moves on the screw to generate a relative displacement, that is, a relative displacement is generated between the hanging buckle push rod 1521 and the screw rod 1522, and according to the relative displacement, when the hanging buckle push rod 1521 moves downwards, the curtain motor 15 moves upwards; when the hanging buckle push rod 1521 moves upwards, the curtain motor 15 moves downwards. When the curtain motor 15 moves upward or downward, the host hanging buckle 154 and the hanging buckle push rod 1521 remain stationary.
When the controller 153 and the driving device 151 cooperate to detect a slippage of the curtain motor 15, a clasping function may be activated, and the clasping function may be specifically operated by adjusting the distance between the driving wheel 1511 and the curtain rail through the tensioning mechanism 152, for example, to make the driving wheel 1511 closer to the curtain rail.
