The other end of the motor 20 is provided with a rectangular structure, and is fixedly connected with the first end cover 106 through the rectangular structure. One end of the synchronous rotating shaft 103 inserted into the roller shutter shaft 102 is a cross-shaped protrusion, the outer portion of the roller shutter shaft 102 is circular, the inner portion of the roller shutter shaft 102 is cross-shaped hollow, the protrusion is matched with the hollow, the other end of the synchronous rotating shaft 103 is rotatably connected with the second end sealing cover 107, and the second end sealing cover 107 axially limits the synchronous rotating shaft 103. The motor 20 is fixed to the roller shutter shaft 102 through the end of the oval structure, and drives the roller shutter shaft 102 to rotate through the structure. The cross-shaped protrusion of the synchronous rotating shaft 103 is in clearance fit with the cross-shaped hollow-out 0 of the roller shutter shaft 102, so that the reliable insertion of the cross-shaped protrusion and the roller shutter shaft 102 is ensured, and the synchronism of the rotation of the two ends of the roller shutter shaft 102 is ensured.

In this embodiment, the roller shutter shaft 102 has a length greater than 2000mm and an outer diameter of 28mm, and is made of 6063 high strength aluminum alloy. The exterior of the roller shutter shaft 102 is circular, and the interior of the roller shutter shaft is hollow, so that the roller shutter shaft 102 has high rigidity, and the axial deviation of the roller shutter shaft 102 is less than or equal to 1 mm. It is understood that in other embodiments, the roller blind shaft 102 can be a hollow tube and remain within the tube in an axially extending cruciform configuration, thereby reducing the weight of the roller blind shaft 102 while maintaining its strength.

In some embodiments, the shade assembly 10 further includes a shade bar 108 and a number of structural bars 109. The cord rod 108 is mounted to the free end of the cord 101. The structure rod 109 includes a first rod portion and a second rod portion, one end of the first rod portion is rotatably connected to one end of the second rod portion, the other end of the first rod portion is rotatably connected to the roll-up housing 104, and the other end of the second rod portion is rotatably connected to the curtain rod 108. Cord rod plugs 110 are disposed at both ends of the cord rod 108. The structural rod 109 can be folded or unfolded along with the rolling or unfolding of the curtain cloth 101, when the curtain cloth 101 is unfolded, the curtain cloth rod 108 and the structural rod 109 respectively provide structural support for the curtain cloth 101 from two directions, so that the curtain cloth 101 is in a more stretched and flat state, and a good sun-shading effect is ensured.

In this embodiment, the sunshade assembly 10 includes four structural rods 109 made of high strength aluminum alloy YL112, and each pair of the four structural rods 109 is adjacent to each other, and when the first rod portion and the second rod portion are folded, the connecting portions of the first rod portion and the second rod portion are close to each other, and when the sunshade assembly is completely folded, the connecting portions of the first rod portion and the second rod portion are closest to each other, but still keep a certain distance. The structural rods 109 made of high strength aluminum alloy are light in weight and high in structural strength, and four structural rods 109 can adapt to the size of one large cord fabric 101. It will be appreciated that the number of structural bars 109 may be determined by the size of the curtain 101, and need only ensure good structural support for the curtain 101, and is not particularly limited herein.

In some embodiments, a switch (not shown) is disposed on the controller 30, and the switch is controlled to switch between the first position, the second position, and the idle position. When the switch is in the idle position, the controller 30 does not output a control command. When the switch is switched from the idle position to the first position and is less than the first preset time, the controller 30 controls the motor 20 to drive the roller blind shaft 102 to completely roll up the curtain 101. When the switch is switched from the idle position to the second position and is less than the second preset time, the controller 30 controls the motor 20 to drive the rolling shutter shaft 102 to fully unfold the curtain 101. The user can press the winding or unwinding by pressing the switch of the controller 30 for a short time, and the operation is very convenient.

Further, the time required for the curtain 101 to achieve full wind-up or full wind-down is defined as the length of wind-up time.

The controller 30 controls the motor 20 to drive the roller blind shaft 102 to unfold the curtain cloth 101, and the switch is switched from the empty position to the second position again within the winding and unwinding time and is less than the second preset time, the controller 30 controls the motor 20 to stop. When the user presses the winding or unwinding function at the point of use, the user may stop the curtain 101 at the position desired by the user by pressing the switch again when the curtain 101 is wound or unwound to the appropriate position without waiting for the curtain 101 to be completely wound or unwound.

Further, the neutral position is located between the first position and the second position, and the switch is located at the neutral position when no external force is applied. When the switch is switched from the idle position to the first position and is greater than or equal to the first preset time duration, the controller 30 controls the motor 20 to drive the rolling shaft 102 to continuously roll the curtain cloth 101 until the external force disappears. When the switch is switched from the idle position to the second position for a time period longer than or equal to a first preset time period, the controller 30 controls the motor 20 to drive the rolling shutter shaft 102 to continuously unfold the curtain cloth 101 until the external force disappears. Therefore, the user can also select to continuously roll up or unfold the curtain cloth 101 to the position required by the user by pressing the switch for a long time, loosening the switch to the proper position, returning the switch to the empty position under the action of no external force, stopping the motor 20 and rolling up or unfolding the curtain cloth 101 to the position required by the user.

In this embodiment, the first preset time period and the second preset time period are both 1 s. It is understood that the first preset duration and the second preset duration are used as time duration boundaries for distinguishing click-to-click from long-to-press, and may be adjusted according to user habits, which are not specifically limited herein.
