Claims

1. A capacitive sensing anti-pinch structure for a ceiling-mounted screen, comprising a top plate (1) and a ceiling-mounted screen (2) that can be flipped open and closed relative to the top plate, wherein the bottom surface of the ceiling-mounted screen (2) is the screen area, characterized in that: The ceiling screen (2) is provided with rear seats (21) on the left and right sides of the rear part, and the rear seats (21) are hinged to the ceiling screen (2) through the support legs (3). The top plate (1) is provided with slide rails (11) on the left and right sides. The slide rails (11) extend in the front and rear direction. The two rear seats (21) of the ceiling screen are respectively hinged to slide blocks (22), and the slide blocks (22) are slidably set on the corresponding slide rails (11). The upper surfaces of the two rear seats (21) form a clamping area (A) with the top plate respectively. The ceiling screen (2) is provided with a circuit board control module (4). The upper ends of the two rear seats (21) are provided with capacitive sensors (5). The circuit board control module (4) is electrically connected to the capacitive sensors (5) and the driving device of the ceiling screen respectively, so as to control the ceiling screen (2) to stop closing or open in the reverse direction when the capacitive sensors (5) sense that a finger is placed in the clamping area (A).

2. The capacitive sensing anti-pinch structure for ceiling-mounted screens according to claim 1, characterized in that: The upper end of the support leg (3) is connected to the front end of the top plate (1) via hinge shaft A (61), and its lower end is connected to the front end of the rear seat (21) via hinge shaft B (62). The rear end of the rear seat (21) is connected to the slide (22) via hinge shaft C (63).

3. The capacitive sensing anti-pinch structure for ceiling-mounted screens according to claim 1, characterized in that: The slide rail (11) has a groove structure, and the slide block (22) is provided with a slider (221) that is adapted to the groove (111). The slider (221) is embedded in the groove (111) to achieve sliding fit.

4. The capacitive sensing anti-pinch structure for ceiling-mounted screens according to claim 1, 2, or 3, characterized in that: The rear seat (21) includes a housing (211) and a top cover (212), wherein the capacitive sensing element (5) is located inside the housing (211) and covered by the top cover (212).

5. The capacitive sensing anti-pinch structure for ceiling-mounted screens according to claim 4, characterized in that: The rear seat (21) and the capacitive sensing element (5) are in a "U" shape.
