Description

A sliding window automatic control plug-in device

technical field

The utility model relates to a power control mechanism for a wing fan.

technical background

At present, the integrated smart home concept is getting more and more attention, but there is still a long way to go before large-scale realization. Take the intelligent control of the windows of the living room as an example. To make the home intelligent, the automatic control of the windows of the room is essential. For example, the Chinese utility model patent with the application number 01262176.5 and the name "Intelligent Remote Control Automatic Window" discloses a kind of automatic closing in wind and rain, automatic opening of harmful gas exceeding the standard, automatic timing switch, remote control switch, and anti-theft alarm functions. Windows are automatically controlled. However, most of the current residential buildings use ordinary windows, and most of them use ordinary sliding windows. If the whole replacement is done, it will not only include the cost of new window products, but also the construction cost of professional decoration personnel, and will cause the refitted ordinary windows. Scrapping of window materials, forming garbage. Therefore, the automatic window technical scheme that needs to replace the whole window is difficult to popularize and implement on a large scale in reality.

The patent application number is 201020546093.5, and the Chinese utility model patent titled "Automatic window closing device in rainy days" discloses an external device for ordinary windows, which can realize the automatic transformation of ordinary windows, so as to realize the function of automatically closing windows when it rains . However, since the program uses electrical appliances such as motors and control circuit boards, and there is no special power supply method, it is necessary to set up power sockets near the windows; for interior decoration that does not have power sockets next to the windows, it is necessary to modify the interior decoration. . However, in the current home decoration, most of the lines of household appliances are hidden lines in the wall, and the amount of modification work is relatively large, which will limit its large-scale application.

Among the existing automatic window technical solutions, there are functions related to the use of the air conditioner, that is, the windows are automatically closed when the air conditioner is turned on, but there are few functions related to the energy-saving use of the air conditioner. Take indoor air-conditioning cooling at night in summer as an example. The outdoor air temperature usually drops to a temperature suitable for people to sleep after late at night. Indoor accumulation, the air conditioner still needs intermittent cooling, which leads to the late opening of the air conditioner, and the indoor air quality is greatly affected, which is neither energy-saving nor healthy.

With the development of the Internet of Things and smart home technology, there will be more and more functional requirements such as energy-saving use of air conditioners. Existing automatic windows usually seldom consider issues such as modular function expansion and integration into the Internet of Things. One of the reasons why it is difficult to develop in depth and finally be applied on a large scale in an ordinary home environment.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

As shown in Fig. 1 and Fig. 2, the sliding window automatic control plug-in device provided by the utility model includes a main body shell 3 and an accessory slot 4. The main body shell 3 has a motor 5 that can drive the window sash to move. The start and stop of the motor is controlled by a sensor and remote control through a single-chip microcomputer, and the power supply of the electric components is supplied by a solar panel 19 and a supporting storage battery 20 installed on the main body shell.

The main body shell 3 is installed on the bottom of the outdoor window frame by screws to avoid affecting the field of view of the sliding window. The accessory groove 4 is installed on the indoor window frame with screws, and the device in the accessory groove is connected with the circuit board in the main body shell through a cable. Small holes are drilled in the window frame to route this connecting cable.

In the main body shell 3 shown in accompanying drawing 1, miniature motor 5, screw mandrel 10, encoder 12 are installed in the middle of its inner bottom. The optical axis at the two ends of the screw mandrel 10 is fixed by the motor end bearing block 6 and the encoder end bearing block 11; When the electromagnetic clutch 25 was turned on, the motor 5 could drive the screw mandrel 10 to rotate around its own axis, and the output shaft of the encoder 12 would rotate with the screw mandrel to measure the screw mandrel rotation angle and feed back a signal to the signal processing board of the circuit board 13 . The supporting ball nut 7 is provided on the screw mandrel 10, and two parallel planes are milled out on the outer circle of the flange of the ball nut 7. The slide rail 9 is made of self-lubricating polyoxymethylene material, contains the screw 10 and the ball nut 7, and is installed on the inner bottom of the main shell along the axis of the screw. The two planes on the outer circle of the flange of the ball nut 7 are limited by sliding The two inner surfaces of rail 9 can not rotate with screw mandrel. Therefore, when the motor 5 rotates, the ball nut 7 translates along the screw shaft axis. The connecting piece 8 connects the ball nut 7 and the controlled window sash 2 through screws, so as to transmit the translation of the ball nut 7 to the controlled window sash to complete the opening and closing action of the window. A certain gap can be left between the connecting piece 8 and the controlled sash 2, so as to avoid the influence of the installation error on the transmission performance.

There is a strict proportional relationship between the rotation angle of the screw rod 10 and the translational distance of the controlled sash 2. The current position of the controlled sash can be calculated by measuring the rotation angle of the screw rod by the encoder 12. The encoder transmits the data to the circuit board 13, and the circuit board board The single-chip microcomputer on the board performs feedback control, which can make the controlled window sash stay in various desired positions. Since the controlled window sash 2 and the motor 5 are driven by the ball screw motion mechanism, the ball screw motion pair can be driven in reverse, and the frictional resistance is low. When the motor 5 and the electromagnetic clutch 25 are not powered, the electromagnetic clutch is disconnected and the motor outputs The shaft is disengaged from the screw, and the window can be opened and closed manually. In terms of control, the control of the motor 5 and the electromagnetic clutch 25 must meet the requirements of manually opening and closing windows. When the action of the window sash 2 needs to be controlled, the control level for driving the electromagnetic clutch 25 to close is sent to the Power amplifier circuit, after the action ends, the electromagnetic clutch 25 is disconnected under the effect of the corresponding control level. Also due to the use of ball screw drive, the torque and power of the required motor 5 are very small. As a practical implementation, you can choose a rated voltage of 12V, a rated speed of 26r/min, a rated power of 2W, and a rated torque of 0.2N m DC motors, such as the 050BGB-360-09250 motor produced by Shenzhen Jinshunlaiite Co., Ltd.

This type of chip comes with multiple A/D and D/A, multiple 8-bit digital I/O, the power supply voltage is 3V, and the clock source can be an external crystal oscillator. In order to increase the function of using air conditioners for energy saving at night, the remote control signal transceiver 24 adopts the self-learning code remote control signal transmission technology, which can perform code pairing on any air conditioner used indoors. When the temperature is set by the user, the signal processing circuit board sends an instruction to open the window and at the same time turn off the air conditioner through the remote control signal transceiver.
