Abstract: A mounting device for an electric curtain is provided, comprising a mounting rail with opposed first end and second end; a drive device, mounted at the first end of the mounting rail; a power supply device, comprising a power supply box mounted at the second end of the mounting rail, a detachable power supply pack mounted inside the power supply box; an auxiliary circuit board with a power supply interface and a first splicing interface is mounted inside the power supply box, a second splicing interface inserted to the first splicing interface is disposed on the power supply pack, and the drive device is electrically connected to the auxiliary circuit board through a power wire; the separation of power supply device and the drive device facilitates assembling and change of the power supply device, and the power supply pack is easy to change and exposed interface for diversifying power supplies.

Abstract: An external punching-free mounting mechanism for a curtain, comprising a cross beam exposed outside a window frame, a first mounting assembly and a second mounting assembly supporting the cross beam in the window frame in a cooperative way, and the first mounting assembly and the second mounting assembly are oppositely connected to the cross beam; the first mounting assembly and the second mounting assembly can slide in the length direction of the cross beam in the unlocking state; the first mounting assembly and the second mounting assembly are fixed to the cross beam in the locking state; the first mounting assembly and the second mounting assembly are both connected with an auxiliary member used for clinging to the inner frame edge of the window frame.

Abstract: A simply-mounted rope-running curtain is provided comprising an upper mounting portion, a curtain body, at least one pull rope, a lower pull rod, at least one rope clamp, and at least one rope fixing device; an upper end of the curtain body is connected to the upper mounting portion and a lower end of the curtain body is connected to the lower pull rod; the pull rope runs through the upper mounting portion, the curtain body and the lower pull rod; the lower end of the curtain body and the lower pull rod slide up and down along the pull rope; the rope clamp is disposed on the lower pull rod to tightly clamp the pull rope and limit the lower pull rod; the rope fixing device is fixedly disposed below the lower pull rod to fix the free end of the pull rope exposed below the lower pull rod.

Abstract: The present invention provides a width-adjustable instant curtain which comprises a length-adjustable upper mounting portion, a cuttable curtain body, a length-adjustable lower counterweight portion capable of smoothing up a lower end of the curtain body, and a pull rope; the curtain body is connected between the upper mounting portion and the lower counterweight portion, and the pull rope runs through and connects the upper mounting portion, the curtain body and the lower counterweight portion, through the cooperation of the length-adjustable upper mounting portion, the cuttable curtain body, the length-adjustable lower counterweight portion, the finished curtain can be freely re-sized to adapt to different mounting sizes of the window frames. Furthermore, the lower counterweight portion of the curtain can smooth up the lower end of the curtain body to enable the curtain body to unfold smoothly, ensuring the aesthetics of the curtain.

Abstract: A drive device for an electric curtain is provided which comprises an integrally-formed plastic housing and a drawer frame which is disposed in the plastic housing; a drive motor and a control board are mounted on the drawer frame; in the drive device of the present invention, the integrally-formed plastic housing replaces the existing aluminum profile to solve the safety problems of short circuiting, electric conduction and firing due to aluminum scraps left in the housing; such that the entire external structure of the drive device has no section difference and color difference, and there is no broken joint formed at the connection with the plastic end cover, satisfying the market requirements. Furthermore, in the drive device, the drawer frame is slidably disposed in the plastic housing and the drive motor and the control board are supported on the drawer frame, facilitating device assembly and production efficiency.

Abstract: A non-return mechanism for a motor of an electric curtain is provided which comprises a motor and a gearbox that are successively connected; the output end of the gearbox is connected with a non-return component; the non-return component comprises a flange, an output shaft and a non-return block, the output end of the gearbox is provided with an output bracket; the output bracket is in unidirectional drive fit with one end of the output shaft toward the gearbox and they fit within the accommodating cavity; the output shaft and the non-return block, together with the unidirectional drive fit with the output bracket, a non-return force is effectively generated to steadily maintain the curtain at the required position when the motor stops without damaging the gearbox and the motor as the output shaft reversely drives the gearbox and the motor under the effect of an external force or gravity.
