Hidden intelligent electric ceiling curtain

Abstract

The invention discloses a hidden intelligent electric ceiling curtain. Thehidden intelligent electric ceiling curtain comprises a shell and a curtain, a winding pipe and a tubular motor are arranged in the shell, the upper end of the curtain is connected to the winding pipe, a balance weight pull rod is fixed to the lower end of the curtain, and an opening allowing the curtain and the balance weight pull rod to stretch out of or retract into an inner cavity of the shell is formed in a bottom plate of the shell. The hidden intelligent electric ceiling curtain is characterized in that a bottom cover is arranged on the balance weight pull rod, an elastic supporting mechanism is arranged between the bottom cover and the balance weight pull rod, the bottom cover is movably hung on the balance weight pull rod through the elastic supporting mechanism, and the elastic supporting mechanism enables the bottom cover to have the trend of moving upwards relative to the balance weight pull rod all the time. When the tubular motor drives the winding pipe to rotate to wind the curtain and synchronously drives the balance weight pull rod and the bottom cover to move upwards together until the curtain and the balance weight pull rod completely retract into the inner cavity of the shell from the opening, the bottom cover can move upwards along with the balance weight pull rod to just cover the opening of the bottom plate of the shell. The hidden intelligent electric ceiling curtain of the invention has the advantage of long service life.

Description

technical field [0001] The invention relates to the technical field of projection equipment, in particular to a hidden intelligent electric ceiling curtain. Background technique [0002] The structure of the currently used ceiling curtain includes: a shell and a curtain. Inside the shell, there is a winding tube for winding the screen, and a tubular motor controlled by a controller for driving the winding tube to rotate. The upper end of the screen is connected to On the winding tube, the lower end of the curtain is fixed with a counterweight pull rod, and a flip cover that can be turned over to cover the opening of the bottom plate of the shell is hinged at the opening of the bottom plate of the shell through a rotating shaft. An installation pendant is respectively fixed on each side, and each installation pendant is provided with an expansion screw for fixing the installation pendant on the ceiling of the house. When installing the ceiling curtain, first open an installa...

Problems solved by technology

[0003] The ceiling curtain currently used has the following disadvantages: (1) It needs to be equipped with two motors, one is a tubular motor used to control the rotation of the take-up tube, and the other is a flip motor that controls the rotation of the flip cover, which increases the production and use of the enterprise. Cost; (2) When opening the ceiling curtain, it is necessary to control the turning motor to drive the flip cover to open the opening of the bottom plate of the shell, and then control the tubular motor to drive the take-up tube to rotate the unwinding curtain; when closing the ceiling curtain, it is necessary to control the tubular motor first Drive the take-up tube to rotate the roll-up curtain, and after the curtain and the counterweight pull rod are completely retracted into the inner cavity of the shell, then control the flip motor to drive the flip cover to turn over and close the opening of the bottom plate of the shell, which is inconvenient and cumbersome to operate; (3) The flip cover closes the shell every time When the bottom plate is opened, it is directly hard contacted with the bottom plate of the shell, resulting in the flip cover and the shell being easily damaged, which shortens the service life of the ceiling curtain; (4) The flip cover is installed on the shell, and due to the high installation height of the shell, replacement and maintenance are required It is very inconvenient to flip the cover; (5) After the ceiling curtain is installed on the ceiling of the house, there is a gap between the ceiling curtain and the installation opening on the ceiling of the house, which is not beautiful and the installation effect is poor
