Motorized blind system

Abstract

A motorized blind system comprises rolling means, head rail, motor bracket, end cap bracket, motor and limit switch. Head rail and rolling means are connected together by the motor bracket on one end through the mounting head of a motor and a motor driving wheel is engaged with the rolling means and drive it for rotation to lift up a blind fabric. The head rail on the other end is connected with an end cap bracket mounted with a bearing rotatably engaged with a shaft of an end cap on one end and with its other end being inserted into the rolling means. The head rail and rolling means on the end of the end cap bracket are aligned.

Description

technical field [0001] The invention relates to an electric sunshade system, in particular to an electric sunshade system powered by an AC motor or a DC motor. Background technique [0002] The traditional electric sunshade system has the following deficiencies: [0003] 1. Most electric sunshade roller blind systems require direct installation of motors and brackets on the ceiling or walls. Through devices and methods of complex structures designed for safety, a tube with a built-in motor is installed on the bracket, and one end of the tube is connected. Insert the motor installation end, and the other end is plugged with a tail plug. This type of system has very precise requirements on the parallelism and positioning of the motor and the tail plug bracket, coupled with its complicated structure, which not only makes it inconvenient to install and disassemble the system, but also takes up Lots of space. This structure also creates a large gap between the roller blind and...

AI Technical Summary

Problems solved by technology

This type of system has very precise requirements on the parallelism and positioning of the motor and the tail plug bracket, coupled with its complicated structure, which not only makes it inconvenient to install and disassemble the system, but also takes up a lot of space

The structure also creates a large gap between the roller blind and the wall, resulting in excess light and loss of privacy

[0004] 2. At the same time, the wires of the motor can usually only extend from the installation end, so as to determine the volume of the curtain. This requires confirming whether the power supply end or the control end is on the right or on the left; otherwise, the wire should be extended from one end to the other, but this will make the appearance look ugly

[0005] 3. The current electric roller shutter control system requires screws to connect the motor wires and power lines to its terminals one by one

This results in a very time consuming installation and the oversized control box cannot be hidden normally unless it is installed in a false ceiling

However, if the control box is installed on the false ceiling, if the ceiling is not knocked open, the controller cannot be accessed, and maintenance cannot be performed.

The controller is often an electronic circuit, which is more likely to be broken than the motor

[0006] 4. The tubes of electric roller blinds are designed and manufactured for one type of curtain

This also leads to the fact that the curtain cannot be removed for cleaning if the entire system is not removed.

[0007] 5. Accessories of different designs for electric roller blinds. For example, in the current market, most manual roller blind systems require tailoring of pipes and upper beams of different lengths

This also creates inefficiencies in manufacturing and production

[0008] 6. Due to the fourth problem mentioned above (must be slid into the tube before fully assembled) and the fifth problem, the manufacture of the roller blind system must be done in the factory

Once the measured size is wrong or the positioning of the power generation end is wrong, the whole system must be sent back to the factory for adjustment

[0009] 7. All existing roller blind systems are designed for roller blinds only

All of this is time consuming and can affect system reliability if set up incorrectly

Especially when the roller blind is over-rotated, it may be damaged
