[0015] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Please refer to this as well. Figures 1-5 This utility model discloses an automatic sunshade door and window based on light sensing. It mainly generates an electrical signal by sensing light and uses a microcontroller to control the door and window to achieve sunshade. The technical solution disclosed in this utility model will be described below by way of specific embodiments.

[0017] In one specific embodiment disclosed in this utility model, such as Figure 2The light-sensing automatic sunshade door and window includes a frame 1, a dimmer 3, a photosensor 5, and a pull rod 6. Several light-shielding panels 2 are linearly arranged in the middle of the frame 1 and can deflect at an angle within the frame 1, allowing light to pass through the gaps between the panels. All the light-shielding panels 2 are connected to the pull rod 6, thereby synchronously changing the deflection angle of the panels 2. Furthermore, one end of the pull rod 6 is hinged to one end of a connecting rod 7, and the other end of the connecting rod 7 is hinged to the telescopic rod of a drive device 4, which is fixedly installed inside the frame 1.

[0018] In this embodiment, the driving device 4 is connected to the photosensitive controller 5 by circuit. By powering on the driving device 4, the driving device 4 can drive the light-shielding plate 2 to rotate via the pull rod 6. The photosensitive controller 5 receives external light through the dimmer 3. Specifically, light from outside the frame 1 can enter the photosensitive controller 5 through the dimmer 3, and the dimmer 3 can change the amount of light entering the photosensitive controller 5. Thus, according to the usage habits of different users, the dimmer 3 can achieve the effect of door and window shading under different light intensities.

[0019] In some embodiments, such as Figure 3 The photosensitive controller 5 includes a housing 51, a circuit board 53, and a main control chip 54. The main control chip 54 is connected to the photoresistor 52. When the photoresistor 52 is exposed to light, its resistance changes, causing a change in its load voltage and generating a voltage signal. When the main control chip 54 senses the electrical signal of the photoresistor 52, it sends a drive signal. Since the power supply battery 55 is connected to the drive device 4 through a power semiconductor, the drive signal input to the power semiconductor can control the power supply battery 55 to power the drive device 4, thereby driving the light-blocking plate 2 to block the light.

[0020] In this embodiment, the photoresistor 52 is disposed outside the housing 51, and the main control chip 54 is disposed outside the circuit board 53. The main control chip 54 is externally connected to the photoresistor 52, the power semiconductor and the power supply battery 55, thereby collecting external light intensity information and powering the drive device 4 through the power semiconductor.

[0021] In one specific embodiment disclosed in this utility model, such as Figure 3The dimmer 3 includes a knob 31 and a turntable 32. The head end of the knob 31 is fixedly connected to the head end of the adjustment shaft 35, which is rotatably mounted on the frame 1. A pointer 34 is etched on the tail end of the knob 31. Several light-transmitting holes 33 are evenly arranged around the circumference of the adjustment shaft 35 and on the turntable 32. Filters with different light transmittances are placed inside the light-transmitting holes 33. Since the center of the turntable 32 is fixedly connected to the tail end of the adjustment shaft 35, the pointer 34 is used to point to different light-transmitting holes 33 and align them with the photoresistor 52, thereby changing the light transmission of external light to the photoresistor 52.

[0022] In this embodiment, the frame 1 includes an aluminum alloy frame 11, a dimming dial 12, and a transparent plate 13. Two transparent plates 13 are arranged on the front and back of the aluminum alloy frame 11, with several light-shielding panels 2 positioned between them. This structure provides good sound insulation and heat preservation. The two transparent plates 13 also help keep the light-shielding panels 2 clean for extended periods. The dimming dial 12 is located at the top of the aluminum alloy frame 11, with an adjustment shaft 35 rotating in the center. A pointer 34 can point to different graduations on the dimming dial 12 to indicate the alignment of the photoresistor with different light-transmitting holes 33. Furthermore, the transparent plate 13 is a transparent photovoltaic panel and is electrically connected to the power supply battery 55, thereby achieving the technical effect of automatic charging of the power supply battery 55.

[0023] In some embodiments, the light-shielding plate 2 includes a rocker arm 21 and a light-shielding sheet 23. The tail end of the rocker arm 21 is perpendicularly connected to the rotating shaft 22, while the head end is rotatably mounted on the pull rod 6. The rocker arm 21 acts as a crank to drive the rotating shaft 22 to rotate. The axis of the light-shielding sheet 23 is fixed to the rotating shaft 22, which is rotatably mounted within the frame 1. The pull rod 6 has several mounting holes evenly distributed on its side for engaging with the head end of the rocker arm 21, thereby driving the light-shielding sheet 23 to achieve synchronous deflection.

[0024] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
