It is easy to install and remove; if large items are loaded into the trunk and the electric cargo cover needs to be removed, it can be easily and quickly disassembled. The overall structure is simple and convenient to use.

[0004] The electric blinds mentioned above may cause fingers to be squeezed due to operator error during use, which limits their use. Utility Model Content

[0005] The purpose of this invention is to provide an anti-pinch structure for an electric cargo curtain, in order to solve the defect that existing electric cargo curtains are not convenient to prevent pinching injuries.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an electric blind curtain anti-pinch structure, including a main body and a blind curtain main body;

[0007] A curtain body is provided on one side of the main body, a mounting plate is fixed on one side of the curtain body, and a telescopic structure is installed at the bottom of the main body.

[0008] The main body is fixed with locking blocks on both sides, and a protective structure is installed on one side of the mounting plate;

[0009] The protective structure includes a protective pad installed on one side of the mounting plate. The protective pad has an internal mounting groove, and a capacitive sensor is installed inside the mounting groove. A capacitive sensing film is installed on one side of the protective pad.

[0010] Preferably, the telescopic structure includes a drive motor evenly installed at the bottom of the main body, an output shaft is provided at the top of the drive motor, a first hinge rod is installed on the outer wall of the output shaft, and a second hinge rod is provided on the side of the first hinge rod away from the output shaft.

[0011] Preferably, the drive motors are symmetrically distributed at the bottom of the main body, and the output shaft extends into the interior of the main body.

[0012] Preferably, the first hinge rod and the second hinge rod are rotatably connected, and the side of the second hinge rod away from the first hinge rod is rotatably connected to one side of the mounting plate.

[0013] Preferably, the card blocks are triangular in design and are symmetrically distributed on both sides of the main body.

[0014] Preferably, the protective pad is made of rubber.

[0015] Preferably, the capacitive sensor is externally connected to a microcontroller, and the output terminal of the microcontroller is electrically connected to the input terminal of the drive motor.

[0016] The advantages of the electric blind curtain anti-pinch structure provided by this utility model are as follows:

[0017] By setting up a protective structure, when an object or finger moves to one side of the capacitive sensing film, it will change the local capacitance value and be detected by the capacitive sensor. When an object is detected approaching, the capacitive sensor controls the drive motor to stop operating through its external microcontroller to prevent pinching injury, thereby achieving the purpose of preventing the curtain from pinching the operator.

[0018] By incorporating a telescopic structure, starting the drive motor causes the output shaft to rotate, which in turn drives the first hinge rod to rotate synchronously. This allows the device to easily move the mounting plate to one side of the main body via the first and second hinge rods, thereby extending or retracting the main body of the curtain. This achieves the purpose of convenient and quick electric extension and retraction of the curtain. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5 The present invention provides an anti-pinch structure for an electric blind curtain, comprising a main body 1 and a blind curtain main body 2.

[0027] Reference Figure 1 - Figure 4 As shown, a curtain body 2 is provided on one side of the main body 1, and a mounting plate 3 is fixed on one side of the curtain body 2. A telescopic structure 4 is installed at the bottom of the main body 1. The telescopic structure 4 includes drive motors 401 evenly installed at the bottom of the main body 1. An output shaft 402 is provided at the top of the drive motor 401. A first hinge rod 403 is installed on the outer wall of the output shaft 402. A second hinge rod 404 is provided on the side of the first hinge rod 403 away from the output shaft 402. The drive motors 401 are symmetrically distributed at the bottom of the main body 1. The output shaft 402 extends into the interior of the main body 1. The first hinge rod 403 and the second hinge rod 404 are rotatably connected. The side of the second hinge rod 404 away from the first hinge rod 403 is rotatably connected to the side of the mounting plate 3.

[0028] To improve the ease of use of the blind curtain, a telescopic structure 4 is incorporated. Simultaneous activation of two drive motors 401 causes the output shaft 402 to rotate inside the main body 1. A first hinge rod 403 is mounted on the outer wall of the output shaft 402, and this first hinge rod 403 is rotatably connected to a second hinge rod 404. The side of the second hinge rod 404 furthest from the first hinge rod 403 is hinged to one side of the mounting plate 3. As the output shaft 402 drives the first hinge rod 403 to rotate, the first and second hinge rods 403 and 404 push the mounting plate 3 to move, thus causing the blind curtain body 2 to extend or retract, greatly increasing the practicality of the device.

[0029] Reference Figure 1 , Figure 2 and Figure 5 As shown, the main body 1 has locking blocks 5 fixed on both sides, and a protective structure 6 is installed on one side of the mounting plate 3. The protective structure 6 includes a protective pad 601 installed on one side of the mounting plate 3. The protective pad 601 has a mounting groove 602 inside, and a capacitive sensor 603 is installed inside the mounting groove 602. A capacitive sensing film 604 is installed on one side of the protective pad 601. The locking blocks 5 are triangular in design and are symmetrically distributed on both sides of the main body 1. The protective pad 601 is made of rubber. The capacitive sensor 603 is externally connected to a microcontroller, and the output terminal of the microcontroller is electrically connected to the input terminal of the drive motor 401.

[0030] During the use of the electric cargo curtain, operator error may lead to fingers being pinched. To address this, a protective structure 6 is installed, in which a capacitive sensing film 604 is mounted on one side of the protective pad 601. When an object or finger is placed on this side, the local capacitance value changes. A capacitance sensor 603 is installed inside the mounting groove 602 to detect the change in capacitance value. When the capacitance value changes, a microcontroller connected to the capacitance sensor 603 controls the drive motor 401, stopping its operation and preventing further movement of the mounting plate 3 that could cause finger pinching. Furthermore, the protective pad 601 on one side of the mounting plate 3 is made of rubber, providing cushioning and reducing harm in the event of unavoidable compression, thus greatly increasing the practicality of the device.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
