DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor are within the protection scope of the present utility model.

[0041] The present utility model will be described below in detail with reference to the drawings: Figure 1 to the drawings Figure 4 The present utility model will be described below in detail with reference to the drawings:

[0042] As Figures 1 to 4 The present utility model provides a photovoltaic module frame including a frame body 1 and a reinforcing piece 2.

[0043] The frame body 1 forms a cavity structure 10, the cavity structure 10 has a support wall 11 for supporting a laminated piece, a bottom wall 12 arranged opposite to the support wall 11, and a first side wall 13 connecting the support wall 11 and the bottom wall 12.

[0044] The reinforcing piece 2 includes a bottom plate part 20 and a baffle part 21, the baffle part 21 is arranged obliquely, the first end 211 of the baffle part 20 abuts against the frame body 1, and the second end 212 of the baffle part 21 is connected with the bottom plate part 20. An included angle is formed between the baffle part 21 and the bottom plate part 20, and at least one of the bottom plate part 20 and the baffle part 21 is detachably connected with the frame body, so that the installation and dismounting operation of the reinforcing piece 2 is more rapid and convenient. It should be noted that the oblique angle of the baffle part 21 is not limited in the present utility model, and can be designed and selected by the skilled person according to the actual situation. Preferably, in the present embodiment, the oblique angle a of the baffle part 21 is between 120° and 160°, so as to improve the drainage efficiency. Meanwhile, the specific shape of the reinforcing piece 2 is not limited in the present utility model, for example, the reinforcing piece 2 can be composed of the bottom plate part 20 and the baffle part 21 to form a triangular shape.

[0045] The photovoltaic module frame of the present utility model adds the reinforcing piece 2 on the basis of the existing photovoltaic module frame, and the reinforcing piece 2 mainly plays the roles of enhancing the structural stability and drainage. The baffle part 21 of the reinforcing piece 2 is arranged obliquely, which can effectively guide the accumulated water on the back of the photovoltaic module to flow out, avoids the problems of electrical safety risk, structural damage, performance decline and biological growth caused by the accumulated water, reduces the maintenance cost caused by the accumulated water, and improves the reliability and service life of the photovoltaic module.

[0046] Meanwhile, when it is necessary to repair or replace internal components of the photovoltaic module, the detachable reinforcing member 2 makes the operation more convenient, without the need to disassemble the entire module, saving time and labor costs. During transportation, the detachable frame design can reduce the occupied space and reduce the risk of damage. During installation, the position of the frame can be flexibly adjusted according to the actual situation, improving the efficiency and accuracy of installation. If the frame part is damaged, only the frame part needs to be replaced, without the need to replace the entire photovoltaic module, thereby reducing the maintenance cost.

[0047] For different types of installation surfaces (such as roofs, floors, etc.), the detachable frame can be adjusted according to actual needs to adapt to various installation environments, improving the versatility of the photovoltaic module. When the photovoltaic module reaches the end of its service life, the detachable frame facilitates the separation of materials for recycling, which is beneficial to environmental protection.

[0048] In addition, the baffle part 21 and the bottom plate part 20 form an included angle, which can better withstand external forces. Under the action of wind force, vibration and other external forces, the baffle part 21 can disperse part of the force to the bottom plate part 20 and the frame body 1, improving the stability of the entire structure. The first end 211 of the baffle part 21 abuts against the frame body 1, which can play a limiting role, preventing the reinforcing member 3 from shifting and loosening during use, further enhancing the structural strength of the frame and improving the wind resistance, shock resistance and other performance of the photovoltaic module.

[0049] Further, in some specific embodiments, at least one of the bottom plate part 20 and the baffle part 21 is detachably connected with the frame body 1 in various ways, such as Figure 3 As shown, the bottom plate part 20 and the bottom wall 12 are designed to be detachably connected. One implementation is that the cavity structure 10 further has a second side wall 14 arranged opposite the first side wall 13. Correspondingly, the cavity structure 10 is surrounded by the support wall 11, the first side wall 13, the bottom wall 12 and the second side wall 14. It can be understood that the cavity structure 10 is quadrilateral, and the bottom wall 12 and the support wall 11 are arranged opposite to each other, that is, the bottom wall 12 and the support wall 11 form two opposite sides of the cavity structure 10. The side of the bottom wall 12 away from the support wall 11 is formed with a connecting groove 121, and the connecting groove 121 extends to the first side wall 13 and / or the second side wall 14. The bottom plate part 20 of the reinforcing member 2 is formed with a connecting protrusion 201 matched with the connecting groove 121. By matching the connecting groove 121 and the connecting protrusion 201 to connect the frame body 1 in the photovoltaic module frame, when the photovoltaic module is subsequently installed in a pressing block type, the reinforcing member 2 can also be removed and installed for use, while also reducing the overall cost of the photovoltaic module.

[0050] In the embodiments of the present application, as Figure 3As shown, two connecting grooves 121 are provided as an example, one connecting groove 121 extends to the first side wall 13, and the other connecting groove 121 extends to the second side wall 14, which means that the connecting grooves 121 are formed on the first side wall 13 and the second side wall 14, extending along the height of the first side wall 13 and the second side wall 14, and the openings of the connecting grooves 121 are located on one side of the bottom wall 12, that is, the cavity structure on the first side wall 13 and the second side wall 14 forms the connecting grooves 121. The connecting grooves 121 extend to the first side wall 13 and the second side wall 14, respectively, cooperate with the connecting protrusions 201 of the reinforcing member 2, increase the contact area of the connection, and improve the stability of the connection. It should be noted that the connecting grooves 121 and the connecting protrusions 201 can also be fixed by adhesive, and it can be understood that the size of the connecting grooves 121 is slightly larger than the size of the connecting protrusions 201, so that there is a gap between the connecting protrusions 201 and the connecting grooves 121 after cooperation, which is convenient for silicone adhesion and enhances the connection stability.

[0051] Of course, the bottom plate part 20 and the bottom wall 12 are designed to be detachably connected, and another implementation manner is: Figure 1 、 2 As shown in FIG. 4, the bottom plate part 20 is arranged on one side of the bottom wall 12 close to the support wall 11, and at least one first clamping groove 122 is arranged on one of the bottom wall 12 and the bottom plate part 20, and at least one first clamping protrusion 202 matched with the first clamping groove 122 is arranged on the other one. The bottom plate part 20 and the bottom wall 12 are detachably connected through the cooperation of the first clamping groove 122 and the first clamping protrusion 202, so that the bottom plate part 20 and the bottom wall 12 can be quickly connected. During installation, the clamping protrusion only needs to be aligned with the clamping groove and pushed in to complete the connection, greatly improving the installation efficiency. At the same time, when the photovoltaic module needs to be maintained, replaced or installed in a pressing block type, the bottom plate part 20 can be easily detached from the bottom wall 12. This detachable connection mode provides convenience for subsequent operation, reduces the difficulty and time cost in the disassembly process. In addition, the cooperation of the first clamping groove 122 and the first clamping protrusion 202 can provide certain friction and clamping force, so that the connection between the bottom plate part 20 and the bottom wall 12 is more firm. When subjected to external force, this connection mode can effectively prevent the relative displacement between the bottom plate part 20 and the bottom wall 12, ensuring the stability of the photovoltaic module.

[0052] In the embodiment of the present application, the bottom wall 12 is provided with a first clamping groove 122, and the bottom plate portion 20 is provided with a first clamping protrusion 202, four of which are arranged along the length direction of the bottom plate portion 20. The multi-point connection can make the connection between the bottom plate portion 20 and the bottom wall 12 more firm, disperse the stress, and improve the stability of the overall structure. It should be noted that the specific formation size and number of the first clamping protrusion 202 are not limited, which can be selected by the person skilled in the art according to the actual situation. For example, the first clamping protrusion 202 can be a limiting protrusion protruding from the surface of the bottom plate portion 20, which can be embedded in the first clamping groove 122 of the bottom wall 12; or the first clamping protrusion 202 can be a cantilever spring, the free end of which extends into the corresponding installation space through the first clamping groove 122. Whether it is a limiting protrusion or a cantilever spring, it has detachability, and in the installation process, a suitable clamping method can be selected according to the needs to make the installation more convenient and fast.

[0053] In some more specific embodiments, the extension length b of the bottom wall 12 away from the frame body 1 is equal to the length of the bottom plate portion 20, so that the bottom plate portion 20 of the reinforcing member 2 can be completely fitted with the bottom wall 12 of the frame body 1, providing uniform support force after installation; at the same time, it ensures that the bottom wall 12 and the bottom plate portion 20 have a larger contact area, thereby increasing the connection strength between them.

[0054] Further, in some specific embodiments, another implementation manner of realizing the detachable connection between the reinforcing member 2 and the frame body 1 is given, that is, the vertical connecting portion 22 and the frame body 1 are detachably connected. Figure 1 、 2 , as shown in 4, the reinforcing member 2 further has a vertical connecting portion 22, the bottom end of the vertical connecting portion 22 is connected with one end of the bottom plate portion 20 close to the frame body 1, and the top end is connected with the first end 211 of the baffle portion 21, the bottom plate portion 20, the baffle portion 21 and the vertical connecting portion 22 are sequentially connected to form the reinforcing member 2, which is a triangle shape. The triangle has stability, which can provide more reliable support and fixation for the photovoltaic module frame.

[0055] The vertical connecting portion 22 is attached to the first side wall 13 away from the frame body 1, and the vertical connecting portion 22 is attached to the first side wall 13 away from the frame body 1, which increases the contact area with the frame body 1 and improves the stability of the connection. At least one second clamping groove 131 is arranged on one of the vertical connecting portion 22 and the first side wall 13, and at least one second clamping protrusion 221 matched with the second clamping groove 131 is arranged on the other one, which increases the detachable connection between the reinforcing member 2 and the frame body 1, enhances the connection strength, and ensures the stability of the photovoltaic module.

[0056] In the embodiment of the present application, the first side wall 13 is provided with a second clamping groove 131, and the vertical connecting portion 22 is provided with a second clamping protrusion 221, and four second clamping protrusions 221 are arranged along the height direction of the second clamping protrusion 221. It should be noted that the specific design of the second clamping groove 131 and the second clamping protrusion 221 can refer to the design of the first clamping groove 122 and the first clamping protrusion 202, which will not be described here.

[0057] Further, in some specific embodiments, as shown in Figure 1 、 2 , the vertical connecting portion 22, the bottom plate portion 20 and the baffle portion 21 enclose a receiving cavity. In the embodiment, the reinforcing member 2 is a right-angle reinforcing member, wherein the vertical connecting portion 22 is vertically arranged, and the bottom plate portion 20 is horizontally arranged, and the two are perpendicular to each other. Such a design can better adapt to the vertically arranged first side wall 13 and the horizontally arranged bottom wall 12 in the rectangular cavity structure. The shape of the right-angle reinforcing member completely fits the part of the side wall and the bottom wall 12 of the rectangular cavity structure. The vertical connecting portion 22 is attached to the vertical first side wall 13, and the bottom plate portion 20 is attached to the horizontal bottom wall 12, so that the reinforcing member 2 can be closely installed on one side of the cavity structure 10, improving the overall stability and reliability.

[0058] In the embodiment, the reinforcing member 2 further comprises a supporting portion 23 arranged in the receiving cavity, which provides additional internal support for the reinforcing member 2, helps to enhance the strength and stiffness of the entire structure, and enables it to better withstand external loads such as wind, vibration and gravity.

[0059] In the embodiment, one end of the supporting portion 23 is connected to the junction of the vertical connecting portion 22 and the bottom plate portion 20, and the other end extends to the middle of the baffle portion 21, strengthening the triangular structure of the reinforcing member 2. The triangle has stability, so that the tooling member can better withstand external forces in all directions and is not easy to deform. At the same time, the supporting portion 23 extends to the middle of the baffle portion 21, which also provides additional support for the baffle portion 24.

[0060] At the same time, as shown in Figure 4 , a protrusion 7 can also be formed at the junction of the vertical connecting portion 22 and the bottom plate portion 20; and a receiving groove 15 adapted to the protrusion 7 is formed on the frame body 1, realizing plug-in cooperation, so that the connection between the reinforcing member 2 and the photovoltaic module frame is more closely and stably, and at the same time, such plug-in cooperation can effectively prevent the reinforcing member 2 from loosening or shifting during use, ensuring that the photovoltaic module is installed firmly and reliably.

[0061] Further, in some specific embodiments, as shown in Figure 1 、 4As shown, the first limiting boss part 16 is provided at the end of the bottom wall 12 away from the frame body 1, for limiting the reinforcing member 2. And / or the second limiting boss part 17 is provided at the end of the support wall 11 close to the baffle part 21, also for limiting the reinforcing member 2. Through the joint action of the first limiting boss part 16 and the second limiting boss part 17, the freedom of the reinforcing member 2 in the horizontal and vertical directions can be controlled, thereby greatly improving the stability of the overall structure. At the same time, the presence of the limiting boss part can enhance the anti-deformation ability of the entire structure: when the photovoltaic module is subjected to external force, the reinforcing member 2 may be subjected to extrusion or stretching, and if there is no limiting of the limiting boss part, the reinforcing member 2 may be deformed, thereby affecting the installation precision and stability of the photovoltaic module. With the limiting of the limiting boss part, the reinforcing member 2 can better maintain its shape and size, improving the anti-deformation ability of the entire structure.

[0062] In the present embodiment, the end of the bottom wall 12 away from the frame body 1 is bent upward to form the first limiting boss part 16, and the first limiting boss part 16 and the end of the bottom wall 12 enclose a first groove 18 with the opening facing upward, and the shape of the first groove 18 is U-shaped; at the same time, the end of the bottom plate part 20 of the reinforcing member 2 away from the vertical connecting part 22 is provided with a first outer protrusion matching the first groove 18. The end of the support wall 11 close to the baffle part 21 is bent downward to form the second limiting boss part 17, and the second limiting boss part 17 and the end of the support wall 11 enclose a second groove 19 with the opening facing downward, and the shape of the second groove 19 is U-shaped; and the connecting part between the vertical connecting part 22 of the reinforcing member 2 and the baffle part 21 is provided with a second outer protrusion matching the second groove 19.

[0063] Through the cooperation of the first groove 18 of the first limiting boss part 16 and the first outer protrusion of the bottom plate part 20 of the reinforcing member 2, and the cooperation of the second groove 19 of the second limiting boss part 17 and the second outer protrusion at the connecting part between the vertical connecting part 22 of the reinforcing member 2 and the baffle part 21, multi-directional limiting of the reinforcing member in the horizontal and vertical directions is realized, which can more effectively prevent the reinforcing member 2 from shifting or shaking during use, thereby improving the stability of the overall structure.

[0064] At the same time, the cooperation of the U-shaped groove and the outer protrusion makes the installation position of the reinforcing member 2 more accurate. During installation, the outer protrusion can be accurately inserted into the U-shaped groove, ensuring that the reinforcing member 2 is installed in the correct position, improving the accuracy and efficiency of installation. In addition, the cooperation of the U-shaped groove and the outer protrusion increases the contact area between the bottom wall 12 and the bottom plate part 20 of the reinforcing member 2, and between the support wall 11 and the vertical connecting part 22 of the reinforcing member 2, thereby enhancing the connection strength.

[0065] Further, in some specific embodiments, such as Figure 1As shown, the bottom plate part 20 extends to the direction away from the baffle part 21, forming a key-like fixing structure 3. Correspondingly, the bottom wall 12 near the one end of the frame body 1 is formed with an engagement installation groove 4 matched with the fixing structure 3. During installation, the fixing structure 3 is inserted into the engagement installation groove 4, that is, into the internal cavity of the bottom wall 12, so as to realize the secondary fixing of the structure.

[0066] During use, the cooperation of the fixing structure 3 and the engagement installation groove 4 provides the secondary fixing, further enhancing the stability of the structure on the basis of the original connection mode. Even when subjected to a larger external force, the loosening or displacement between the reinforcing member 2 and the frame body 1 can be effectively prevented, which helps to improve the bearing capacity of the whole structure and prolong the service life of the photovoltaic module frame and the reinforcing member 2.

[0067] In addition, during installation, the secondary fixing can be realized only by inserting the fixing structure 3 into the engagement installation groove 4, which is simple and fast in operation and improves the installation efficiency; at the same time, it ensures that the reinforcing member 2 is installed at the correct position, improving the installation accuracy.

[0068] Specifically, the length of the fixing structure 3 is about 10 mm, and the cross-sectional shape is in the form of an elongated strip, and a third external protrusion 30 is formed on the surface of the fixing structure 3. The engagement installation groove 4 is provided with a plurality of second internal grooves 6 arranged at intervals and matched with the third external protrusion 30. In this embodiment, the third external protrusion 30 is arranged on the side away from the supporting wall 11, and two are arranged and distributed at intervals. The second internal grooves 6 are arranged on the side of the engagement installation groove 4 close to the lower surface of the bottom wall 12, and two are also arranged, and the positions are one-to-one corresponding to the positions of the third external protrusions 30.

[0069] The design of the fixing structure 3 increases the contact length with the engagement installation groove 4, improving the stability of the connection. At the same time, the third external protrusion 30 further enhances the friction between the fixing structure 3 and the engagement installation groove 4, preventing loosening, so that the connection between the reinforcing member 2 and the frame body 1 is more firm, and can better withstand external forces such as wind force, vibration, etc.

[0070] Of course, a plurality of first internal grooves 5 arranged at intervals can also be arranged on the lower surface of the bottom wall 12 near the one end of the frame body 1, and the first internal grooves 5 and the second internal grooves 6 are arranged in staggered peaks.

[0071] The staggered peak arrangement makes the first internal grooves 5 and the second internal grooves 6 not in the same position, and after the fixing structure 3 is inserted into the engagement installation groove 4, a complex concave-convex interlaced structure is formed, which greatly increases the contact area, thereby increasing the friction. The increase of the friction makes the connection between the reinforcing member 2 and the frame body 1 more firm and not easy to loosen, and can better withstand external forces such as wind force, vibration, etc.

[0072] The utility model discloses on the basis of above photovoltaic module frame still provided a kind of photovoltaic module, and the photovoltaic module includes above photovoltaic module frame.The utility model provides the photovoltaic module has adopted all technical solutions of above photovoltaic module frame all embodiments, thus at least has all beneficial effects brought by the technical scheme of above photovoltaic module frame embodiment, here no longer elaborates one by one.
