As shown in fig. 1 and fig. 2, in order to achieve the purpose of the present utility model, a photovoltaic module frame corner combining module comprises a corner module body 2 with an included angle structure, and two included angle end faces 221 of the corner module body 2 are respectively provided with two connecting parts 222 extending outwards in parallel.

The angle code body 2 of the angle code assembly has two extending portions 220 with a certain angle included angle with each other, for example, a right angle code with a 90 ° included angle commonly used in the angle code assembly of a rectangular frame, or an acute angle code with an included angle smaller than 90 ° in a triangular frame, or an obtuse angle code with an included angle larger than 90 ° in a polygonal frame, or even an angle code with a circular arc structure, so that the extending portions 220 form a certain included angle with each other, that is, a perpendicular line 41 is led from the free end surfaces of the two extending portions 220, that is, the included angle end surfaces 221, and the two perpendicular lines 41 intersect to form a certain included angle 42, which is not limited to the extending portions which are only linear. The front end surfaces of the two extending portions 220, that is, the angled end surfaces 221, and two parallel connection portions 222 extending outwards are disposed on the two angled end surfaces 221, where the parallel is not strictly limited to the geometric parallel, but also includes a non-parallel form, so long as the use requirement can be satisfied. When the frame corner is assembled, the corner connector 222 and the extension 220 are inserted into the corner cavity of the profile, and then the pins with diameters larger than the distance between the two connectors 222 are used to squeeze between the two connectors 222, so that the two connectors 222 are forced to deform outwards, and the outer side surfaces of the connectors 222 are in tight contact with the inner wall of the corner cavity of the profile, so that interference fit connection is formed. Because the structure characteristics of the utility model can prepare the corner connector with the size slightly smaller than that of the corner connector cavity, the corner connector can be easily placed without reusing a corner connector pressing tool when the corner connector is assembled on the frame, and the protruding points in interference fit do not need to be prefabricated on the section bar. And finally, expanding the connecting part by using the pin so as to form interference connection. When the frame is required to be disassembled, the frame can be conveniently disassembled only by taking down the pins. When the angle code is used, pre-drilling holes are needed at the positions corresponding to the connecting parts so as to facilitate the installation of pins. The sectional material with the open corner bracket cavity invented by the applicant can be used for directly installing the pin from the opening, so that the installation is very convenient.

In the preferred embodiment, the two connecting portions 222 on the same angled end face 221 are provided with arcuate grooves 225 on opposite sides for mounting the pins 3. The provision of the arcuate slot 225 may facilitate pin installation.

Preferably, the opposite side surfaces of the two connecting parts 222 on the same included angle end surface 221 are respectively provided with a protruding part 224 extending oppositely, and the protruding part 224 is provided with the arc-shaped groove 225. The provision of the boss 224 allows the arc-shaped groove 225 to be formed while ensuring the thickness dimension and mechanical strength of the connecting portion 222, and allows the pin 3 to be further downsized while ensuring a sufficient deformation amount.

Preferably, the outer side surface of the connecting portion 222 is provided with flat teeth 223. The flat teeth 223 can further increase the friction force between the connecting part 222 and the inner wall of the section bar corner bracket cavity, and prevent the frame from loosening.

Preferably, a portion of the connecting portion 222 near the angled end surface 221 has a smaller thickness than a portion thereof distant from and adjacent to the angled end surface. Indicated at 228 in fig. 2. This facilitates the deformation and holding elasticity of the connection portion 222.

Preferably, the outer side surface of the corner connector body 2 is provided with a plane chamfer 226 or an arc chamfer. The setting of chamfer can avoid forming the interference between angle sign indicating number and the section bar, does benefit to quick installation angle sign indicating number.

Preferably, the inner side surface of the corner connector body 2 is provided with a circular arc groove 227. The arrangement of the circular arc groove 227 is beneficial to the processing of the corner connector and the improvement of quality.

Preferably, one or more hollow structures are arranged between the two included angle end faces 221 of the corner connector body 2.

The corner connector provided by the utility model can be made of a material with certain elasticity, so that the connecting part 222 is elastically deformed after being installed into the pin, and can be restored after the pin is removed, and the corner connector can be conveniently installed and detached. Of course, the connecting part can also be made of inelastic materials, so that the connecting part cannot recover after being deformed after being filled with the pin. The choice of materials is determined according to the actual needs.

Taking the assembly of the right triangle frame as an example, as shown in fig. 3, a right triangle assembly frame is formed by assembling three sections 1, three joints are fixedly connected by three corner codes, the triangle frame shown in fig. 3 has included angles of 90 degrees, 60 degrees and 30 degrees respectively, and the included angles of the three corner codes are also 90 degrees, 60 degrees and 30 degrees respectively, if the right triangle assembly frame is a traditional closed corner code cavity, at least one corner code cannot be installed, and only the fixed connection of the frame can be carried out in other modes, so that the working efficiency is affected. By adopting the section bar 1 provided by the applicant, when in assembly, the openings 19 of the three section bars 1 are upwards placed and are well placed according to the shape of the triangular frame, then, the corner connector with the corresponding included angle is only required to be downwards placed into the corner connector cavity 16 from the opening 19, and finally, the corner connector and the section bar 1 can be fixed through pins, so that the frame assembly is completed. The first problem that the profile of the existing closed corner bracket cavity can not be smoothly assembled by utilizing the corner bracket, such as a triangular frame and other special frames is solved. Second, the assembly of the present utility model is more efficient than the assembly of inserting the corner codes one by one from the corner code cavity ports.

The applicant provides a section bar that angle sign indicating number chamber has opening as shown in fig. 4, a section bar 1 for photovoltaic module frame, section bar 1 cross section includes:

the assembly mounting groove 12 is positioned above the corner bracket cavity 16, and the assembly mounting groove 12 is a groove with a side opening;

the corner connector cavity 16 is used for sleeving a corner connector to connect a plurality of section bars 1 to form a photovoltaic module frame, and the corner connector cavity 16 is a cavity with an opening 19.

In practical application, when the existing frame assembly equipment is utilized for automatic production, if the angle codes are adopted by all the angles, as the sectional materials forming the edges of the frame are movably pre-assembled together, the sectional materials are required to be fixed firstly when the equipment is put into the angle codes, so that the equipment parts are increased, and the efficiency is reduced. Therefore, the two acute angle corner brackets adopt the traditional corner brackets according to the mode shown in fig. 3, the equipment firstly processes two bulges 10 on the inner side wall of the corner bracket cavity of the profile, then presses one end of the traditional corner brackets into the corner bracket cavity of the bevel profile, then sequentially inserts two right angle side profiles into the corresponding one side corner brackets, and forms interference fit through the bulges 10 and the traditional corner brackets, at the moment, three sides of the triangular frame are fixed in place, the equipment is not required to fix all sides, only the corners of the right angle side are not connected by the corner brackets, at the moment, the novel corner brackets provided by the utility model can be conveniently placed into the corner bracket cavity 16 from the opening 19 of the corner bracket cavity 16 by the equipment, and pins are installed at the opening, so that the corner bracket connection is also completed at the right angle connection position. Rectangular or polygonal frames are assembled similarly. Of course, the corner connector can be used entirely, and only the equipment is required to be adaptively modified.

In the example of fig. 3, the 30 ° acute angle corner 21 and the 60 ° acute angle corner are conventional corners and the 90 ° right angle corner 22 is the novel corner provided by the present utility model. The free ends of the corner brace are opened to two sides by the pins, so that interference fixed connection with two side walls of the corner brace cavity 16 is realized. The choice of the structure of the corner pieces can be determined according to the need, and is not limited to the corner pieces with a certain shape.

The utility model also discloses a photovoltaic module, which comprises the photovoltaic module frame.
