Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

Example 1

As shown in fig. 1 to 3, a frame structure of a solar photovoltaic module comprises a frame body 1, wherein the frame body 1 comprises a cavity 11 for inserting and fixing a corner fastener, a first clamping groove 12 arranged on one side of the cavity 11 for fixing a solar photovoltaic panel,

an elastic part 2 is embedded in the first clamping groove 12, and the elastic part 2 is a rubber clamping groove; the elastic part 2 comprises a U-shaped second clamping groove 21, the outer diameter of the elastic part 2 is the same as the inner diameter of the first clamping groove 12, and the inner diameter of the second clamping groove 21 of the elastic part 2 is the same as the thickness of the solar photovoltaic panel;

in order to enhance the assembly reliability between the solar photovoltaic panel and the second clamping groove when the solar photovoltaic panel is embedded in the second clamping groove, a plurality of rows of first protrusions 3 are arranged on the upper inner side surface and the lower inner side surface of the second clamping groove 21 of the elastic part 2; the sealing performance between the solar photovoltaic panel and the elastic piece is enhanced;

further, the first protrusions 3 on the upper side surface and the first protrusions 3 on the lower side surface of the second clamping groove 21 are arranged in a staggered manner; therefore, the local stress of the first bulge on the solar photovoltaic panel can be reduced;

in addition, a skirt 23 is convexly arranged at the notch of the elastic part 2 close to the first clamping groove 21, meanwhile, a second protrusion 4 is arranged on the outer side surface of the elastic part 2, a groove 5 is arranged at the position of the upper side surface of the first clamping groove 12 close to the notch, a bent part 51 is arranged at the position of the groove 5 far away from the notch, the curvature of the bent part 51 is the same as that of the second protrusion 4, and the diameter height of the groove 5 is the same as that of the second protrusion 4;
