[0010] Furthermore, the anti-pinch buffer mechanism includes: a buffer support spring and a buffer lifting plate; multiple sets of buffer support springs are provided, and the multiple sets of buffer support springs are respectively fixedly connected to the upper end of the buffer drive slider; the buffer lifting plate is slidably connected above the buffer drive slider, and the lower end of the buffer lifting plate is slidably connected to the buffer support spring.

[0011] Furthermore, the anti-pinch buffer mechanism also includes a buffer contact plate; the buffer contact plate is fixedly connected to the upper end of the buffer lifting plate, and the buffer contact plate is a rectangular rubber block structure.

[0012] Furthermore, the anti-pinch buffer mechanism also includes: a buffer drive component, a first buffer rack, a buffer drive gear, and a second buffer rack; two sets of buffer drive components are provided, and the two sets of buffer drive components are slidably connected to the upper left and right sides of the anti-pinch buffer base respectively; two sets of first buffer racks are provided, and the two sets of first buffer racks are fixedly connected to the lower end of the buffer drive component respectively; two sets of buffer drive gears are provided, and the two sets of buffer drive gears are rotatably connected to the inner left and right sides of the anti-pinch buffer base respectively, and the two sets of first buffer racks mesh with the buffer drive gears respectively; two sets of second buffer racks are provided, and the two sets of second buffer racks are fixedly connected to the left and right sides of the buffer drive slider respectively, and the two sets of second buffer racks mesh with the buffer drive gears respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model, through the setting of the opening and closing protective mechanism, allows the buffer lifting plate to move upward and push the protective shield plate. At this time, the protective shield plate tilts backward, pushing off the debris on the surface of the protective shield plate. This prevents debris on the surface of the protective shield plate from affecting the falling of the lifting door, ensuring the stable closing of the lifting door and improving the overall usability of the garage door.

[0015] This invention utilizes an anti-pinch buffer mechanism. When the lifting door panel moves downward, it presses against the buffer drive component. The buffer drive component, being pressed downward, moves downward, causing the first buffer rack to move downward. The first buffer rack moves downward, causing the buffer drive gear to rotate. The rotation of the buffer drive gear causes the second buffer rack to move upward, which in turn causes the buffer drive slider to move upward. The upward movement of the buffer drive slider causes the buffer support spring to move upward, which in turn causes the buffer lifting plate to move upward. The upward movement of the buffer lifting plate extends out of the anti-pinch buffer base. At this point, the buffer contact plate and the buffer support spring together achieve an anti-pinch effect for the user, preventing injury and improving the overall safety of the garage door.
