As shown in fig. 1, a mounting mechanism for roofing glass-based thin film solar energy in one embodiment presented herein comprises: a base 100, said base 100 for mounting on a building roof 800; a subframe 200, wherein the subframe 200 is used for installing the thin film solar module 900; the fixing component comprises a pressing block 300 and a fastener 400, the base 100 is connected with the pressing block 300 through the fastener 400, and the pressing block 300 fastens and fixes the auxiliary frame 200 on the base 100; wherein, the pressing block 300 and the sub-frame 200, and the sub-frame 200 and the base 100 are respectively in plane contact fit.

The mounting mechanism is mainly used for paving the glass-based thin-film solar module 900 on a pitched roof. Specifically, during installation, the base 100 may be installed on a roof of a building, the thin film solar module 900 and the sub-frame 200 are fixedly assembled, and finally the press block 300 is installed on the base 100 through the fastener 400, so that the assembly is completed. Because after the installation, briquetting 300 is under the fastening force effect of fastener 400, tightly withhold the sub-frame 200 and fix on base 100, and at this moment, briquetting 300 and sub-frame 200, and all cooperate with plane contact between sub-frame 200 and the base 100, compare in the traditional point fixed mode that adopts the screw, area of contact between each part of this technical scheme is bigger, mutual butt is more firm, make the structural strength of installation mechanism after whole dress allies oneself with high, even if when great exogenic action is come in thin-film solar module 900 transmission, damage such as deformation or fracture can not take place for installation mechanism, the structural safety can satisfy the designing requirement, the operational reliability is high.

In order to improve the overall structural strength of the mounting mechanism, the auxiliary frame 200, the base 100 and the pressing block 300 can be made of stainless steel, aluminum alloy, hard plastic and other materials; in the embodiment, the components can be made of aluminum alloy, so that the roof-mounted LED lamp has the advantages of light weight and high structural strength, and is suitable for being used in occasions with high mounting strength on roofs.

The base 100 is composed of two right and left angle aluminum, a base frame, and a bolt assembly. When the aluminum roof is installed, the left and right corner aluminum are fixed on the building roof 800 by welding, riveting, screwing and the like. And then the base frame is clamped between the left and right angle aluminum through the bolt assembly. For realizing just installing the location and further promoting the dress and alling oneself with intensity, the left and right sides face of base framework all is equipped with first sawtooth structure, controls two angle aluminium and is equipped with second sawtooth structure respectively towards the side of base framework, first sawtooth structure and the meshing of second sawtooth structure to can promote longitudinal load's bearing capacity.

In an alternative embodiment, the fastening member 400 is a fastening screw, and threaded holes are respectively formed in corresponding positions of the pressing block 300 and the top surface of the base 100, and the fastening screw is screwed in the two threaded holes. The subframe 200 includes a first frame 210 and a second frame 210a arranged at an interval, a bottom plate of the first frame 210 and a bottom plate of the second frame 210a are matched at an interval to form a through hole opposite to and communicated with the threaded hole, one side of the pressing block 300 facing the base 100 is provided with a ring-shaped supporting body 310, and an end of the ring-shaped supporting body 310 abuts against the top surface of the base 100. During installation, the hand of an operator can directly extend into the auxiliary frame 200 to screw the fastening screw, so that the fastening screw is in threaded connection with the two threaded holes. Further, in order to improve the connection strength, the number of the fastening screws may be two or more, and correspondingly, the number of pairs of the screw holes is also two or more, and one fastening screw is connected with a pair (two) of the screw holes in a matching manner, so that the fixing and fastening firmness of the pressing block 300, the sub-frame 200 and the base 100 may be improved by increasing the connection point.

However, in consideration of strength, the bottom plate of the sub-frame 200 (i.e., the horizontal plate sections of the first frame 210 and the second frame 210a that are attached to the base 100) should have a certain thickness, and when the fastening screws are continuously screwed into the screw holes, the pressure generated will deform or even break the suspended portion of the pressing block 300 at the upper end of the through hole. Therefore, the annular support body 310 is arranged on one side of the suspended part facing the base 100, so that the normal installation of the fastening screw cannot be influenced, and the annular support body can abut against the top surface of the base 100, thereby supporting the pressing block 300, improving the assembling performance of the pressing block 300, and preventing the suspended part in the middle of the pressing block 300 from being deformed or even broken.

On the other hand, in order to balance the strength and the weight, a thickened body 110 is provided on the inner side of the top surface of the base 100, and the thickened body 110 is provided with the threaded hole.
