Description

Technical Field

[0001] The utility model relates to the technical field of building windows, in particular to a built-in photovoltaic electric blind that is self-adaptive to light and temperature. Background Art

[0002] In the prior art, glass windows and Venetian blinds are the main building components and are widely used in residences, office buildings, etc. Although traditional glass windows with built-in Venetian blinds play an important role in shading and protecting privacy, their user experience has some obvious shortcomings.

[0003] Common window products with light-sensing functions currently on the market typically control the opening and closing of Venetian blinds by detecting the intensity of outdoor light. However, these systems mostly rely on a single light sensor, which cannot accurately determine the sun's position or light fluctuations. Due to their simple structure, existing technologies are unable to perform more complex and precise adjustments based on varying environmental parameters. This results in a low level of intelligent control and fails to meet users' increasing demands for energy conservation, comfort, and optimized indoor lighting environments.

[0004] Traditional light-sensing blinds often close in strong sunlight. However, due to a lack of comprehensive understanding of factors such as temperature and light angle, they can close prematurely or late, resulting in poor indoor comfort and excessive energy consumption. Furthermore, these blinds lack the flexibility to precisely control the rotation of the blades and the raising and lowering of the blinds based on varying light and temperature conditions, limiting their application in more complex environments. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1-3 As shown, a built-in photovoltaic electric blinds with light and temperature self-adaptation includes a window frame 1, a glass cover 2, a blind 3, a blind electric drive device 5, a light sensor 6 and a temperature sensor 7. The specific implementation structure is as follows:

[0033] Window frame 1:

[0034] The window frame 1 comprises a top sill 11, a bottom sill 12, and two side sills 13. The frame is constructed of aluminum alloy or high-strength plastic, offering strong corrosion and weather resistance. A top frame 14 is mounted on the underside of the top sill 11. This frame 14 features a photovoltaic panel slot 141 facing outward, and a drive device cavity 142 and a Venetian blind storage slot 143 facing inward. The Venetian blind storage slot 143 is located below the drive device cavity 142.

[0035] The top septum 11 has two sides that are glued, and a top septum clip is located in the middle of its bottom surface, running along the length of the top septum. The top surface of the top frame 14 is equipped with a top frame clip that interlocks with the top septum clip, and L-shaped support structures are installed at both ends of the top frame to enhance its stability.

[0036] The top frame 14 includes a frame body 14a and a cover plate 14b. The outer side of the frame body 14a is a photovoltaic panel slot 141, and the inner side is a driving device slot. The cover plate 14b covers the opening of the driving device slot 142 to form a closed driving device cavity 142.

[0037] PV panel slots 141 are each provided with photovoltaic trough baffles 144, each with a C-shaped longitudinal cross-section. Inserted into each end of the slots 141, these baffles stabilize the panels, preventing them from shaking while also shielding their edges for enhanced aesthetics. Furthermore, these baffles 144 are provided with light holes, corresponding to the positions of the light sensors 6.

[0038] Glass cover 2:

[0039] The glass cover 2 is made of double-layer tempered glass, installed on the inner and outer sides of the window frame, forming a hollow interlayer. The Venetian blinds 3 are located in the hollow interlayer, and the blinds are intelligently raised and lowered and the blades are turned by the electric drive device of the blind body.

[0040] Photovoltaic panel 4:

[0041] Photovoltaic panels 4, mounted within slots 141 in the top bulkhead 11, utilize high-efficiency monocrystalline silicon panels. Grid baffles 144 stabilize the panels and enhance their aesthetics. These panels provide power to the energy storage battery 32, which is managed by a solar charge controller 34.

[0042] Curtain electric drive device 5:

[0043] The electric drive device 5 for the curtain body includes: a drive motor 51 , a venetian blind shaft 52 , a turning seat 58 , a drive rope 53 , a motor limiter 54 , a solar charging controller 55 , an energy storage battery 56 and a control circuit board 57 .

[0044] like Figure 4As shown, the energy storage battery 56, the solar charging controller 55, the control circuit board 57 and the drive motor 51 are integrated in a device box. The inner cavity of the device box is divided into a motor cavity, a battery cavity, a control circuit board cavity and a solar controller cavity by a partition, and the motor cavity is located in the front, and the battery cavity, the control circuit board cavity and the solar controller cavity are located side by side in the rear.

[0045] The energy storage battery 56 preferably uses a lithium battery pack, which supplies power to the control circuit board 57 and its connected devices. The control circuit board 57 is connected to the drive motor 51 and the motor limiter 54 respectively.

[0046] The control circuit board 57 uses an STM32F103 microcontroller as its main control chip. It is responsible for receiving and analyzing data from the light sensor 6 and the temperature sensor 7, and adjusting the height and blade angle of the Venetian blind according to changes in the external environment. The control circuit board 57 controls the operation of the drive motor 51 through the motor limiter 54.

[0047] A drive motor 51 and a motor stopper 54 are mounted on either end of the Venetian blind shaft 6. The drive motor 51 controls the raising and lowering of the Venetian blind and the reversing of the blind blades. The Venetian blind shaft 52 is connected to the drive motor 51, and a reversing mount 58 is mounted on the Venetian blind shaft 52. One end of a drive cord 53 is wrapped around the reversing mount 58, and the other end is connected to the Venetian blind 3. The drive motor 51 drives the rotation of the Venetian blind shaft 52 to achieve the raising and lowering and reversing of the blind. The motor stopper 54 controls the upper and lower limits of the Venetian blind 3 to prevent the motor from over-operating.

[0048] Motor limiters 54 use Omron D2F series or Honeywell V7 series motor limiters. These are compact, precise, easy to install, and well-matched with micro DC motors, ensuring the system's position control accuracy and durability. These limiters are widely available and reliable.

[0049] Light Sensor 6:

[0050] Two light sensors 6 are located at either end of the photovoltaic panel 4, facing each side at a 45-degree angle. They sense the intensity of light coming from either direction. These two light sensors 6 are connected to the control circuit board 57 via an I2C bus, transmitting light signals to the control circuit board 57. The control system determines the sun's position by comparing the difference in light intensity between the two sides. The BH1750 light sensor is preferred.

[0051] Temperature sensor 7:

[0052] The temperature sensor 7 is installed on the outside of the window frame to detect the external ambient temperature and transmit the temperature signal to the control circuit board 57. Preferably, a DHT22 or TMP36 sensor is used.

[0053] Working principle Figure 5 As shown:

[0054] 1. Sensor monitoring:

[0055] The light sensor 6 detects the external light intensity in real time and transmits the light information to the control circuit board 57 via the I2C bus;

[0056] The temperature sensor 7 detects the external temperature and transmits the signal to the control circuit board 57 .

[0057] 2. Control system decision-making:

[0058] The control circuit board 57 determines the external light and temperature conditions based on the sensor data and controls the drive motor 51 to adjust the state of the venetian blind 3, including:

[0059] Adjust the height of the blinds;

[0060] Adjust the tilting angle of the blades (via the blind shaft 52).

[0061] 3. Power supply:

[0062] The photovoltaic panel 4 absorbs solar energy and charges the energy storage battery 56 through the solar charge controller 55, ensuring that the system can still operate normally when there is insufficient sunlight.

[0063] Through this structure, the system can effectively realize automatic curtain control according to changes in light and temperature, thereby achieving the effects of energy saving and optimizing the indoor environment.
