[0023] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0024] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0025] As described in the background technology, traditional bracket systems mostly adopt fixed or adjustable angle designs, but the installation process is complicated, and the installation of traditional bracket systems is complicated; and traditional support frames basically have upper outlets (conductors), which easily bring the risk of water leakage.

[0026] Based on the above reasons, this embodiment provides a photovoltaic support frame, such as Figure 1-Figure 3 As shown, the photovoltaic support frame includes a support member 100 and a protective cover 200, the support member 100 includes two vertical vertical bonding parts 101, a wire groove 103 is formed between the two vertical bonding parts, and the outer side of the vertical bonding part has a horizontal support part 102;

[0027] The protective cover 200 covers the open end of the wire slot 103 .

[0028] The above-mentioned technical features can realize the support of photovoltaic tiles, or the photovoltaic tiles are installed on the horizontal support part through other auxiliary parts, so as to realize the support of photovoltaic tiles; the horizontal support part is a plane support method to provide support force for the photovoltaic tiles, and it is also convenient for the staff to level the photovoltaic tiles. The vertical fitting part can limit the end face of the photovoltaic tiles. At the same time, a wire groove for side outlet can be formed through two vertical fitting parts. The wire groove can be protected by a protective cover to prevent water from entering the wire groove and affecting the normal operation of the wires.

[0029] In order to introduce the wires at the bottom of the photovoltaic tile into the wire trough, in one embodiment, Figure 2 As shown, a lead hole 105 is provided at the bottom of the wire slot 103. This technical feature can prevent the photovoltaic tile from leading out the wire from the top, because if the photovoltaic tile leads out from the top, it is not convenient to waterproof, and it is easy to have leakage and water seepage.

[0030] In order to realize the snap connection between the protective cover and the vertical fitting portion, in one embodiment, as Figure 4As shown, the upper end of the vertical fitting portion has a first protrusion 106, and the lower end surface of the protective cover 200 is provided with a second protrusion 202 opposite to the first protrusion 106, and the first protrusion 106 is buckled with the second protrusion 202. The two protrusions can achieve a snap connection, and the protrusions can form an S-shaped contact path at the contact point, reducing the risk of rainwater entering the cable trough.

[0031] In order to realize the snap connection between the protective cover and the vertical fitting portion, in another embodiment, as Figure 2 and Figure 5 As shown, the inner side of the protective cover 200 is formed with two engaging grooves 201 adapted to the vertical fitting part, and the outer side of the vertical fitting part is engaged with the engaging groove by a serrated part. The serrated engagement can prevent the protective cover from falling off and ensure the stability of the engagement. The serrated engagement can increase the contact area. After increasing the contact area, adding structural adhesive can improve the tightness of the connection. At the same time, the serrated engagement can form multiple S-shaped contact paths to reduce the risk of rainwater entering the cable trough.

[0032] Since the flat photovoltaic tiles are generally connected to the support by bonding when installing, and the photovoltaic tiles are generally directly bonded or more often the connectors are installed on the photovoltaic tiles, and bonded to the support through the connectors, in order to make the flat photovoltaic tiles or the connectors adapted to the flat photovoltaic tiles better connected to the support and more stable, in one embodiment, the outer surface of the horizontal support portion 102 and the vertical bonding portion 101 has a rough portion, and the outer surface is bonded to the connector or photovoltaic tile. Optionally, the rough portion is a rough surface. The contact area between the adhesive and the support is increased by the rough surface, and the bonding stability is improved; preferably, the rough portion is formed by several parallel ridges. The rough portion formed by several mutually parallel ridges can increase the contact area of ​​the structural adhesive and improve the bonding and sealing effects; even if there is water leakage on the top, several ridges can also improve the water blocking effect, and the adjacent ridges can also form a longitudinal drainage channel, and can also achieve longitudinal drainage, thereby preventing water from entering the bottom of the photovoltaic tiles downward, thereby improving the waterproof effect.

[0033] When installing the support, the support is installed on the purlin (such as Figure 6 and Figure 7 As shown), therefore, in order to better drive the self-tapping screws into the support member, in one embodiment, a fastener positioning portion 104 is provided on the inner side surface of the vertical fitting portion 101 and / or the bottom surface of the wire groove. The fastener positioning portion is formed by two parallel ridges, and the purpose is to reduce the deviation of the self-tapping screws when driving them.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
