Description

Technical Field

[0001] This utility model belongs to the field of electric louver glass technology, specifically involving the improvement of a thin controller for photovoltaic electronically controlled louvered insulating glass. Background Technology

[0002] Electric-driven insulated glass units with built-in blinds achieve on-demand raising and lowering of the blinds and on-demand slat rotation by effectively controlling the motor's operating status, such as forward or reverse rotation and the degree of rotation. With the widespread adoption of fully automated intelligent products, electric insulated glass units with built-in blinds are increasingly showing a trend towards intelligent development. Existing technology already employs wireless control devices, which typically consist of a transmitter and a receiver. Wireless communication is achieved primarily through radio frequency, infrared, and Bluetooth methods. The receiver receives signals transmitted by the transmitter to control the motor's operation.

[0003] There is no shortage of technical information about wireless control devices for electrically driven insulated glass with built-in blinds in the published Chinese and foreign patent documents, such as CN214315250U (a low-power wireless receiver for electrically driven insulated glass with built-in blinds) and CN222125843U (a touch wireless receiver controller for electrically driven insulated glass with built-in blinds). The above-mentioned prior art has the following disadvantages: (1) The controller has a built-in battery. In order to ensure sufficient number of operation times, the battery must have a certain volume, making the controller larger; (2) Because of its certain volume and weight, the installation of the controller requires the design of a special mounting bracket or mounting plate, which increases the cost of use and makes the installation work cumbersome; (3) The controller is fixedly installed on the upper part of the insulated glass with a mounting plate. The current market trend of window glass is towards large area, and the installation height of the controller is constantly increasing. The controller is difficult to install and extremely inconvenient to disassemble.
