Considering the manufacturing cost of the assembly, the frame of the photovoltaic assembly is mostly made of composite materials at present, but the mechanical strength of the composite materials is low, especially in the frame assembling process, the acting force of the angle keys at the splicing position of the frame of the composite materials and the inner wall of the frame cavity is insufficient, and the situation that the frame assembling does not reach the standard, even the frame falling off and the angle key explosion frequently occurs. Directly influences the efficiency and quality of framing processing.

Therefore, the embodiment of the application provides the photovoltaic frame, the splicing part of the frame base materials adopts a rigid connection mode, and the rigid connection mode generates larger friction force, so that a firm connection relation is formed between the angle keys and the frame base materials, the mechanical connection strength is enhanced, and the phenomena of frame detachment and angle explosion are not easy to occur.

As shown in fig. 1-9, a photovoltaic frame comprises a frame base material 2 with a cavity 1, and further comprises an angle key 3, wherein the angle key 3 comprises two bending parts 12 which are perpendicular to each other, the bending parts 12 are inserted into the cavity 1, the two ends of the cavity 1 are respectively provided with a first metal part 4, the first metal parts 4 protrude into the cavity 1, the bending parts 12 are provided with second metal parts 6, and the second metal parts 6 protrude out of the surface of the bending parts 12 and are in butt fit with the first metal parts 4, so that the bending parts 12 are fixed in the cavity 1.

The frame substrate 2 is a basic profile constituting a photovoltaic frame, and in general, the photovoltaic frame may be formed by splicing a plurality of frame substrates 2, and the splice is provided with a connecting piece for fixing. Since the photovoltaic frame is generally a rectangular frame, the frame base material 2 can be further divided into a long frame base material 2 and a short frame base material 2.

Therefore, the frame substrate 2 provided in the embodiment of the present application may be regarded as a profile for forming a photovoltaic frame.

The interior of the rim substrate 2 is provided with a cavity, which may be referred to as a cavity 1. The cavity 1 may penetrate through the frame base material 2 or may be disposed at two ends of the frame base material 2. Since the two ends of the frame substrate 2 are usually used for connecting other frame substrates 2, the two ends of the frame substrate 2 need to be provided with the cavities 1 to meet the splicing requirement of the frame substrate 2. An angle key 3 can be inserted into the cavity 1 for connecting adjacent frame base materials 2. Whether the corner key 3 is firmly connected with the cavity 1 directly influences the mechanical connection strength of the splicing part of the frame base material 2. The connection mode of the visible angle key 3 and the cavity 1 plays a crucial role in the stability of the spliced frame base material 2.

The corner key 3 is a fixing member for connecting the two frame base materials 2. The angle key 3 can be inserted into the cavity 1 and tightly attached to the inner wall of the cavity 1 to generate larger friction force, so that the angle key 3 is firmly connected with the frame base material 2 and is not easy to separate.

It should be noted that, the plurality of holes 13 are mounting holes for mounting the second metal member 6, and the plurality of mounting holes do not penetrate the bottom of the groove 5, and have a certain depth. Thus, in one embodiment, the height of the plurality of cartridge posts 10 is no greater than the depth of the holes 13 so that the cartridge posts 10 form a better mating connection with the holes 13.

The heights of the plurality of inserting columns 10 can be set to be the same size or different sizes, but the depth of the holes 13 matched with the inserting columns is correspondingly set so as to ensure that the second metal piece 6 is stably installed in the groove 5. In a preferred embodiment, the height of each pair of matingly mounted cartridge posts 10 is set to be the same as the depth of the holes 13.
