In this embodiment, the bottom frame unit 2 and the cover plate unit 3 form a photovoltaic module frame with a U-shaped cross section, so as to cover and protect the module main body plate 1 therein, thereby preventing the side edges thereof from being damaged by collision easily. Of course, the photovoltaic module frame cannot be too wide, which would reduce the illuminated area required for photovoltaic power generation.

In addition, the hinged cylinder unit 5 can be used or not, when it is used, the supporting column b is inserted into it, and the actual supporting height of the supporting column b can provide a large adjustable range of the inclined angle for the assembly body plate 1 after being integrally adjusted, so that the photovoltaic assembly can obtain a relatively good inclined illumination angle when the installation position is changed, or in different use seasons.

When the hinged cylinder unit 5 is idle, the connecting plate unit 4 is directly and fixedly mounted on the inclined plate a of the frame body, and at this time, the photovoltaic module has relatively high mounting strength although the inclination angle cannot be changed.

The two installation methods can be optional and can be replaced mutually at any time, which is one of the embodiments of the flexibility of the use effect of the photovoltaic module.

The bottom frame unit 2 includes a rectangular frame bottom plate 201, a rectangular frame side plate 202 disposed on an upper surface of the rectangular frame bottom plate 201, and a screw groove 203 disposed on an upper surface of the rectangular frame side plate 202 and used for mounting the cover plate unit 3.

In this embodiment, the rectangular frame bottom plate 201 and the rectangular frame side plate 202 are integrally formed, that is, the cross-sectional shape is L-shaped, the assembly body plate 1 is placed therein, and finally the cover plate unit 3 is covered, so that the assembly body plate 1 can be ensured to be installed more conveniently in the following.

The cover unit 3 includes a rectangular frame flat plate 301 provided on the rectangular frame side plate 202, and a mounting bolt 302 provided on the rectangular frame flat plate 301 and used for connecting the screw groove 203.

In this embodiment, the rectangular frame plate 301 has a shape of an outer rectangular side plus an inner rectangular side, and is provided with a circular hole for inserting the mounting bolt 302.

In addition, the lower surface of the rectangular frame plate 301 and the upper surface of the assembly main body plate 1 cannot be clamped in multiple degrees, and the distance between the lower surface and the upper surface is 1.0-1.5mm.

The cover plate unit 3 further includes an outer annular groove 303 provided on a lower surface of the rectangular frame plate 301 and configured to be engaged with the rectangular frame side plate 202.

In this embodiment, the outer annular groove 303 is a circle of rectangular annular groove formed on the outer side of the lower surface of the rectangular frame side plate 202, and is used for butting against the rectangular frame side plate 202, so that the rectangular frame flat plate 301 has a unique accurate position in the butting and mounting action on the bottom frame unit 2.

The connection plate unit 4 includes an orifice plate 401 disposed on the lower surface of the rectangular frame body base plate 201, and a screw 402 disposed on the orifice plate 401 and used to connect the frame body inclined plate a and/or the hinge cylinder unit 5.

In this embodiment, the threaded member 402 is a bolt and a nut.

When the screw 402 is separately connected to the frame body inclined plate a, the hinge cylinder unit 5 is idle and is entirely removed; when the screw 402 is separately connected to the hinged cylinder unit 5, the photovoltaic module is installed through the support column b; when the screw connector 402 is connected with the frame body inclined plate a and the hinged cylinder unit 5, the photovoltaic module is installed on the frame body inclined plate a, the hinged cylinder unit 5 is installed on the side edge of the screw connector 402, and the hinged cylinder unit 5 does not interfere with the installation of the frame body inclined plate a.

Therefore, the length of the screw 402 needs to be relatively large.

The number of the orifice plates 401 is 8 in total, and the orifice plates are respectively arranged at four end corner positions on the lower surface of the rectangular frame bottom plate 201 in a manner of being grouped in pairs.

In this embodiment, the frame body inclined plate a is also provided with a perforated plate, and the screw 402 passes through 2 perforated plates 401 and 1 perforated plate, that is, the installation of one end corner of the photovoltaic module is completed.

The hinge cylinder unit 5 includes a hinge plate 501 provided on the screw 302, and a cylinder 502 provided on the hinge plate 501 and inserted with a mounting support column b.

In this embodiment, the hinge plate 501 is located between the two hole plates 401, and the hinge plate 501 does not touch the lower surface of the rectangular frame bottom plate 201 during the rotation process, so the acute angle between the cylinder 502 and the main assembly plate 1 may be larger or smaller, and the inclination angle corresponding to the main assembly plate 1 may be relatively larger or smaller, i.e. it is relatively vertical or relatively "lying down".

The hinge cylinder unit 4 further includes a laterally extending plate 503 provided on the hinge plate 501 and used for mounting the cylinder 502 in a laterally displaced manner when the screw 402 is coupled to the frame body inclined plate a.

In this embodiment, the laterally extending plate 503 has at least the following two advantages.

First, when the hinged cylinder unit 5 is used, due to the existence of the transverse extension plate 503, the cylinder 502 and the support column b are relatively close to the edge and the outside, and at this time, if the photovoltaic module is a dual-glass photovoltaic module, that is, if the module main body plate 1 includes the glass back plate 1-1, the outward movement of the support column b can further reduce the blocking amplitude of the photovoltaic module installation structure to reflected light, and can also improve the power generation efficiency of the dual-glass photovoltaic module.

Secondly, when the hinged cylinder unit 5 is idle and still installed on the screw 402, the hinged cylinder unit 5 is located at the outer sides of the two hole plates 401, and the hole plate of the inclined plate a of the frame body is located at the inner sides of the two hole plates 401. It is necessary that the hinge cylinder unit 5 be kept away from the frame body inclined plate a at this time just by the presence of the laterally extending plate 503.

The articulated cartridge unit 5 further comprises an end plate 504 arranged at the upper end opening of the cartridge 502.

In this embodiment, the end plate 504 is a stable end point for inserting the support column b into the cylinder 502, so as to ensure the stable installation of the latter.

Without the end plate 504, there may also be a problem of insufficient connection between the hinge plate 501 and the barrel 502.

The hinge cylinder unit 5 further includes an elastic buffer block 505 disposed in the cylinder 502 on the lower surface of the head plate 504 and elastically supporting the support column b.

In this embodiment, the elastic buffer block 505 is made of rubber with medium elasticity and high strength, and is bonded to the end plate 504, so as to ensure that a buffer structure is formed between the support pillar b and the assembly main body plate 1, thereby avoiding the direct impact of the assembly main body plate 1 with high strength as much as possible.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the appended claims.
