Description

Technical Field

[0001] This utility model belongs to the field of smart home technology and relates to a photosensitive driven automatic curtain opening and closing device. Background Technology

[0002] With the rapid development of smart home technology, smart curtains, which enhance living comfort, have been widely used in various architectural spaces such as homes and offices. Photosensitive driven curtains, with their ability to automatically respond to changes in ambient light, can open and close the curtains without human intervention. This avoids indoor overheating or glare caused by direct sunlight and maximizes the use of natural light to reduce lighting energy consumption, making them one of the mainstream development directions in the field of smart curtains. A search of Chinese patent publication number CN211269889U reveals an intelligent curtain control system, which describes a system that "includes an electric guide rail, a servo motor for driving the electric guide rail, and a curtain mounted on the electric guide rail; it also includes a main control device, a light detector, a first light sensor, a support rod, and a second light sensor; the main control device includes a power module, a first microprocessor, a servo motor drive module, and a wireless receiving module." This technical solution effectively addresses the problem that existing electric curtains cannot intelligently detect the position of light and cannot intelligently adjust the movement of the curtains according to the position of direct sunlight. However, the above technical solutions can only achieve full opening or full closing of the curtains as a whole. When the light sensor detects strong light, it cannot meet the needs of some users who want to partially close the curtains to block light while keeping some areas light-transmitting. It also cannot achieve precise opening control such as half-opening the curtains, resulting in insufficient ease of use. Utility Model Content

[0003] The technical problem to be solved by this utility model is that when the light sensor detects strong light, it cannot meet the needs of some users who want to partially close the light and keep some areas light-transmitting, nor can it achieve precise opening control such as half-opening the curtains, resulting in insufficient ease of use. To overcome the shortcomings of the existing technology, a photosensitive driven automatic curtain opening and closing device is provided.

[0004] The present invention discloses a photosensitive driven automatic curtain opening and closing device, comprising a control box and an electric track curtain body. The control box is located on one side of the electric track curtain body. An MCU control board is installed at the bottom of the inner cavity of the control box. A battery is installed at the bottom of the inner cavity of the control box away from the MCU control board. A cover is installed on the top of the control box. A position sensing component, located at the bottom of the control box, is used to control the extreme positions of the curtains opening or closing. The positioning component is used in conjunction with the sensing component and can be freely disassembled, while also serving to fix the position of the control box.

[0005] Preferably, the position sensing component includes a rotating plate, a square tube, a square rod, a fixed electrical contact, and a buffer spring. The rotating plate is rotatably connected to the bottom of the control box. The square tube is fixedly connected to the outer side of the rotating plate. The square rod is slidably connected to the inner side of the square tube. The fixed electrical contact is fixedly connected to the end of the square rod away from the rotating plate. A buffer spring is fixedly connected between the end of the square rod away from the fixed electrical contact and the outer side of the rotating plate.

[0006] Furthermore, the position sensing component also includes movable hanging rings, L-shaped rods, and movable electrical contacts. Several evenly distributed movable hanging rings are installed at the bottom of the electric track curtain body. An L-shaped rod is fixedly connected to the side of the movable hanging rings closest to the control box away from the electric track curtain body. Movable electrical contacts are fixedly connected to both ends of the L-shaped rod, and the movable electrical contacts match the fixed electrical contacts.

[0007] Preferably, the positioning component includes a mounting plate, a mounting opening, a lifting plate, a buckle plate, a limiting rod, limiting holes, and a return spring. The mounting plate is fixedly connected to the bottom of the control box near the electric track curtain body. The mounting plate has a mounting opening on one side. The lifting plate is slidably connected to the inside of the mounting opening. The side of the lifting plate away from the mounting plate extends to the bottom of the rotating plate. The top of the lifting plate is fixedly connected to the limiting rod. The bottom of the rotating plate has evenly distributed limiting holes. The top of the limiting rod extends to the inside of the limiting holes. A return spring is fixedly connected between the bottom of the lifting plate and the bottom of the inner cavity of the mounting opening.

[0008] Furthermore, the positioning assembly also includes a buckle plate, a pull cord, a pull ring, a fixing ring, and a T-shaped slide rail. A pull cord is fixedly connected to the bottom of the lifting plate near the mounting plate. A fixing ring is fixedly connected to the side of the mounting plate away from the motor track curtain body. The bottom end of the pull cord passes through the fixing ring and is fixedly connected to the pull ring. The side of the lifting plate away from the limiting rod extends to the outside of the mounting opening. Buckles are fixedly connected to both the control box and the side of the lifting plate away from the fixing ring. A T-shaped slide rail is provided between the inner sides of the two buckles. The side of the T-shaped slide rail away from the control box is fixedly connected to the motor track curtain body.

[0009] Furthermore, the positioning component also includes a rectangular opening, a roller, a positioning post, and a positioning hole. Two rectangular openings are symmetrically opened on the inner sides of the two buckles. A roller is installed inside the rectangular opening. A positioning post is fixedly connected to the bottom of the inner cavity of the lower buckle near the middle. The bottom of the T-shaped slide rail has evenly spaced positioning holes. The top of the positioning post extends into the inner side of the positioning hole.

[0010] Working Process: When using this technical solution, first install the motorized track curtain body in the desired location and place the light sensor on the motorized track curtain body in a suitable position so that it is not obstructed by objects. Next, adjust the position of the control box as needed. First, pull the lifting plate and the buckle plate downward by pulling the ring and the pull cord, compressing the return spring and causing the positioning post to disengage from the positioning hole. Then, push the entire control box along the T-shaped slide rail to the left or right. When it slides to the appropriate position, release the ring, and the return spring simultaneously pushes the lifting plate and the buckle plate upward, causing the positioning post to enter the inside of the positioning hole, thus fixing the position of the entire control box and preventing it from changing position during use. If the curtain retracts towards the motor of the motorized track curtain body to open the window, then the position of the control box is the limit position that restricts the curtain from closing.

[0011] When the light sensor on the electric track curtain body detects strong light, it controls the motor of the electric track curtain body to start. The motor drives the movable hanging ring to move the curtain towards the control box, thus closing the curtain. Simultaneously, the movable hanging ring drives the L-shaped rod and the movable electrical contact to slide towards the control box. When the movable electrical contact contacts the fixed electrical contact, the MCU control board receives the signal and controls the motor on the electric track curtain body to stop running.

[0012] Furthermore, if it is necessary to control the extreme position of the closed curtains, first, pull the lifting plate down using the above operation to disengage the limit rod from the limit hole. Slide the control box to the desired position, rotate the rotating plate and square tube to rotate the fixed electric contact piece in the other direction, and then release the pull ring to allow the lifting plate to rise and drive the limit rod into the limit hole, thus fixing the position of the rotating plate and the adjusted fixed electric contact piece. When the curtains are closed, the movable electric contact piece contacts the fixed electric contact piece, which will also control the motor on the electric track curtain body to stop working. In addition, if you want to remove the control box, you can use the above operation to pull the pull ring to lower the lifting plate and the latch plate, push the control box upward and move it outward to separate it from the T-shaped slide rail, which can effectively improve the convenience of use.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the cooperation between the control box, rotating plate, square rod, fixed electric contact piece, movable electric contact piece and movable hanging ring, the motor track curtain body can drive multiple movable hanging rings to slide towards the control box, so that the movable electric contact piece on the movable hanging ring contacts the fixed electric contact piece on the control box, thereby closing the motor track curtain body, and allowing the movable hanging ring to pull the curtain to partially open or close to a specified position. 2. Through the cooperation of the lifting plate, buckle plate, return spring, limit rod and positioning column, the lifting plate can be pulled down to adjust the direction of the rotating plate to adapt to the position of the curtain being closed and opened. Pulling the lifting plate can disengage the control box from the T-shaped slide rail, achieving the purpose of disassembly. When the lifting plate is released, the position of the control box and the rotating plate can be fixed and changed, which can effectively improve the convenience of use. Attached Figure Description

[0019] Example 2 like Figures 3-7As shown, the positioning assembly includes a mounting plate 2, a mounting opening 11, a lifting plate 12, a buckle plate 13, a limiting rod 14, a limiting hole 15, and a return spring 16. The mounting plate 2 is fixedly connected to the bottom of the control box 1 near the electric track curtain body 20. A mounting opening 11 is provided on one side of the mounting plate 2, and a lifting plate 12 is slidably connected to the inside of the mounting opening 11. The lifting plate 12 extends to the bottom of the rotating plate 3 on the side away from the mounting plate 2. A limiting rod 14 is fixedly connected to the top of the lifting plate 12.

The positioning assembly also includes a buckle plate 13, a pull cord 17, a pull ring 18, a fixing ring 19, and a T-shaped slide rail 27. A pull cord 17 is fixedly connected to the bottom of the lifting plate 12 near the mounting plate 2. The mounting plate 12 extends to the bottom of the electric track curtain body 20.

The bottom end of the pull cord 17 passes through the fixing ring 19 and is fixedly connected to the pull ring 18. The side of the lifting plate 12 away from the limiting rod 14 extends to the outside of the installation opening 11. The control box 1 and the side of the lifting plate 12 away from the fixing ring 19 are both fixedly connected to the buckle plate 1. A T-shaped slide rail 27 is provided between the inner sides of the two buckle plates 13. The side of the T-shaped slide rail 27 away from the control box 1 is fixedly connected to the motor track curtain body 20. The positioning component also includes a rectangular opening 24, a roller 25, a positioning post 26 and a positioning hole 28. Two rectangular openings 24 are symmetrically opened on the inner sides of the two buckle plates 13. A roller 25 is installed inside the rectangular opening 24.

The bottom of the T-shaped slide rail 27 is provided with evenly spaced positioning holes 28. The top of the positioning post 26 extends to the inside of the positioning hole 28.

[0020] Working Principle: When using this technical solution, firstly, the motorized track curtain body 20 is installed in the desired location, and the light sensor on the motorized track curtain body 20 is placed in a suitable position so that it is not obstructed by objects. Next, the position of the control box 1 is adjusted as needed. First, the lifting plate 12 and the buckle plate 13 are lowered by the pull ring 18 and the pull cord 17, which compresses the return spring 16, causing the positioning post 26 to disengage from the positioning hole 28. Then, the control box 1 is pushed to slide left or right along the T-shaped slide rail 27. When it slides to the appropriate position, the pull ring 18 is released, and the return spring 16 pushes the lifting plate 12 and the buckle plate 13 to rise simultaneously, causing the positioning post 26 to enter the inside of the positioning hole 28, thereby fixing the position of the control box 1 and preventing it from changing position during use. If the curtain retracts towards the motor of the motorized track curtain body 20 to open the window, then the position of the control box 1 is the limit position that restricts the curtain from closing.

[0021] When the light sensor on the electric track curtain body 20 detects strong light, it controls the motor of the electric track curtain body 20 to start. The motor drives the movable hanging ring 8 to slide the curtain towards the control box 1, thus closing the curtain. Simultaneously, the movable hanging ring 8 drives the L-shaped rod 9 and the movable electrical contact 10 to slide towards the control box 1. When the movable electrical contact 10 contacts the fixed electrical contact 6, the MCU control board 21 receives the signal and controls the motor on the electric track curtain body 20 to stop running.

[0022] Furthermore, if it is necessary to control the extreme position of the closed curtain, firstly, pull the lifting plate 12 down through the above operation, so that the limiting rod 14 disengages from the limiting hole 15. Slide the control box 1 to the desired position, rotate the rotating plate 3 and the square tube 4, so that the fixed electric contact 6 rotates to another direction. Then, release the pull ring 18, so that the lifting plate 12 rises and drives the limiting rod 14 into the limiting hole 15, thereby fixing the position of the rotating plate 3 and the adjusted fixed electric contact 6. When the curtain is closed, the movable electric contact 10 contacts the fixed electric contact 6, which will also control the motor on the electric track curtain body 20 to stop working. In addition, if you want to remove the control box 1, you can use the above operation to pull the pull ring 18 to lower the lifting plate 12 and the buckle plate 13, push the control box 1 upward and move it outward to separate it from the T-shaped slide rail 27, which can effectively improve the convenience of use.

[0023] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
