Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, unless expressly stated or limited otherwise, the terms "connected," "connected," and "fixed" are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
Referring to fig. 1, an embodiment of the present invention provides a photovoltaic module 1, including a photovoltaic glass 11 and a mounting base 12 molded on a back side of the photovoltaic glass 11, where a fixing hole 121 is formed in the mounting base 12, and a bottom and a side wall of the fixing hole 121 are spaced apart from the photovoltaic glass 11, the mounting base 12 includes a first mounting plate 122 molded on the back side of the photovoltaic glass 11, a second mounting plate 123 molded on an edge of the photovoltaic glass 11, and a third mounting plate 124 molded on a light receiving surface of the photovoltaic glass 11, and the first mounting plate 122, the second mounting plate 123, and the third mounting plate 124 are integrally molded to wrap the edge of the photovoltaic glass 11, so as to provide more directional structural protection.
According to the embodiment of the invention, the mounting seat 12 is injection molded on the photovoltaic glass 11, the process of packaging the aluminum profile frame is not carried out, and the bottom and the side wall of the fixing hole 121 on the mounting seat 12 are arranged at intervals with the photovoltaic glass 11, so that the requirement of fixing and positioning the photovoltaic component 1 of the mounting seat 12 is met, the fixing hole 121 does not penetrate through the mounting seat 12 and does not contact with the photovoltaic glass 11, and the photovoltaic component 1 with a simple structure is formed.
Generally, the injection molded mounting base 12 can be made of various plastic materials, however, in order to ensure stronger temperature resistance and stronger structural strength of the molded mounting base 12, in one embodiment, the mounting base 12 is a thermosetting plastic base, and is injection molded by using thermosetting plastic. Since the thermosetting plastic can soften and flow when heated for the first time, and is heated to a certain temperature to generate a cross-linking reaction to cure and harden, the change is irreversible, and then the thermosetting plastic cannot soften and flow again when heated again, and the thermosetting plastic can be cured into a product with a determined shape and size by virtue of the characteristic of molding processing, so that the mounting base 12 made of the thermosetting plastic in the embodiment of the invention has larger temperature resistance and structural strength compared with the mounting base made of the thermoplastic plastic.
In addition, the fixing hole 121 on the mounting seat 12 may be disposed at a position on the back side of the photovoltaic glass 11 or at a position on the edge, but in order to maximize the light receiving area of the photovoltaic module 1 to achieve the maximum power generation efficiency, the fixing hole 121 is not generally disposed at the light receiving surface of the photovoltaic glass 11, that is, at the third mounting plate 124, and therefore, in one embodiment, the width of the first mounting plate 122 is greater than that of the third mounting plate 124, so that the area of the light receiving surface of the photovoltaic glass 11 occupied by the mounting seat 12 can be reduced while the light receiving surface of the photovoltaic glass 11 is protected by the third mounting plate 124 of the mounting seat 12.
Also, in order to provide sufficient space for the first mounting plate 122 and the second mounting plate 123 to be provided with the fixing holes 121, referring to fig. 1, in one embodiment, the thickness of the first mounting plate 122 is greater than that of the third mounting plate 124, and also, the structure of the third mounting plate 124, in which the fixing holes 121 do not need to be provided, is made more compact.
Referring to fig. 1, as a preferred embodiment of the photovoltaic module 1, the edge or corner or the combination of the edge and the corner of the mounting seat 12 is provided with a transition structure 125, in this embodiment, the edge of the mounting seat 12 may be a contact edge between every two surfaces, and the corner of the mounting seat 12 may be a corner formed by every three surfaces. The transition structure 125 may include any one of a chamfer structure, a fillet structure, and an arc transition structure, or any combination structure, so that sharp portions such as edges or corners of the mounting base 12 are passivated, and personal injury caused by mounting the photovoltaic module 1 provided by the embodiment of the present invention is reduced.
As a preferred embodiment, the fixing holes 121 formed in the mounting seat 12 may be threaded holes, and according to the weight of the photovoltaic module 1 and the bearing strength of the photovoltaic bracket 2, screws with specifications of M6 × 12 or more may be selected. In order that the screws do not penetrate the mounting base 12 and do not contact the photovoltaic glass 11 after mounting, in one embodiment, the thickness of the mounting base 12 injection molded on the back side of the photovoltaic glass 11 is 2cm to 3 cm. Through setting up certain thickness's mount pad 12 in this embodiment, can leave sufficient space and set up fixed orifices 121 at the dorsal part of photovoltaic glass 11 or border, avoid the screw to have the risk of running through mount pad 12 or contacting photovoltaic glass 11 after the installation.
In the installation process of the photovoltaic module 1, the collision between the photovoltaic modules 1 can be inevitably generated, and in order to reduce the damage caused by direct collision between the photovoltaic modules 1, in one embodiment, the edge of the photovoltaic glass 11 is provided with a buffer rubber strip 13, so that the buffer rubber strip 13 can absorb collision energy when the photovoltaic modules 1 directly collide, thereby reducing the external force on the photovoltaic glass 11 in the photovoltaic modules 1 and avoiding the damage. The cushion rubber strip 13 may be fixed in an adhering manner, or may be fixed in a buckling manner, and the embodiment of the present invention is not particularly limited.
In the production of the photovoltaic module 1, the glass surface of the tempered glass 111 in the photovoltaic glass 11 is generally as smooth as possible in order to improve the light transmittance as much as possible. However, the smooth glass surface is not favorable for the connection between the mounting seat 12 and the photovoltaic glass 11 during injection molding, and in order to increase the connection strength between the mounting seat 12 injection-molded on the photovoltaic glass 11 and the photovoltaic glass 11, in one embodiment, a frosted surface is arranged at a position on the photovoltaic glass 11 where the mounting seat 12 is required to be injection-molded, so that the surface contact area on the photovoltaic glass 11 is increased, and the connection strength between the mounting seat 12 and the photovoltaic glass 11 is enhanced.
In the embodiment, because the secondary processing such as hole opening, cutting, grinding and the like is not allowed to be performed due to the characteristics of the tempered glass 111, the tempered glass 111 of the embodiment of the invention can be subjected to frosting treatment on the position of the glass where the injection molding mounting seat 12 is required before the raw material glass is subjected to tempering treatment, then the tempered glass 111 is subjected to tempering treatment to form the tempered glass 111, and then the tempered glass 111, the EVA112 and the crystalline silicon wafer cell string 113 are laminated to form the photovoltaic glass 11, so that not only is the frosting surface required on the glass when the injection molding mounting seat 12 is ensured, but also the risk that the tempered glass 111 is damaged due to the processing of the tempered glass 111.
The invention also provides an embodiment of a photovoltaic system, as shown in fig. 2 and fig. 3, the photovoltaic system includes a photovoltaic support 2 and a photovoltaic module 1 shown in fig. 1, and a fixing member 3 can be inserted into a fixing hole 121 on a mounting seat 12 of the photovoltaic module 1, so that the photovoltaic module 1 is fixed on the photovoltaic support 2 through the fixing member 3. The photovoltaic system provided by the embodiment of the invention is assembled by the photovoltaic module 1 with a simple structure, so that the technical effect of convenience in assembly can be achieved. The fixing member 3 may be a screw or a rivet, and the embodiment of the present invention is not particularly limited.
