Description

Technical Field

[0001] The utility model relates to a skylight structure, in particular to a frame installation point anti-cracking structure. Background Art

[0002] In existing skylight structures, the structures of the driving mechanical area, sunshades, etc. are mostly realized by using motor-driven racks. The motor is installed on the front frame or the rear frame and is connected using a raised mounting seat with a built-in metal insert. During use, the large reverse torque of the motor acts on the mounting seat and insert at the installation point, which can easily cause deformation and damage. In addition, the installation of the insert increases the difficulty of frame molding and production costs. Summary of the Invention

[0005] The width of the process groove is 0.5 of the frame thickness.

[0006] The thickness of the reinforcing rib is 0.4 of the thickness of the frame.

[0007] The frame material is preferably pp-gf50.

[0008] The bottom edge of the mounting boss and the upper end surface of the frame are transitioned via an arc corner.

[0009] The mounting boss is in an inverted trapezoidal shape.

[0010] The reinforcing rib is hollowed out at the corner of the bottom edge of the mounting boss on the upper end surface of the frame.

[0011] The beneficial effects of the utility model are:

[0012] 1. The process groove is opened on the mounting boss to release the large torque reaction stress after the motor is tightened and installed, avoiding the cracking of the overall grooveless boss structure and improving the stability and safety of use;

[0013] 2. The side reinforcement ribs are set to effectively improve the overall strength; the mounting boss can also be set to an inverted trapezoidal shape, combined with the reinforcement ribs to further improve the support stability and structural strength of the motor.
