Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic components, and in particular to a photovoltaic frame and a photovoltaic assembly. Background Art
[0002] The function of the photovoltaic module is to convert solar energy into electrical energy, or to store it in a battery, or to drive a load to work. Generally, the photovoltaic module includes a photovoltaic frame and a photovoltaic panel mounted on the photovoltaic frame, wherein the photovoltaic frame is provided with a mounting notch 600', the photovoltaic panel is inserted into the mounting notch 600', and the photovoltaic panel and the mounting notch 600' are fixed by gluing.
[0003] Figure 1 The cross-sectional structure diagram of the photovoltaic frame provided by the prior art. Figure 1 As shown, the photovoltaic frame includes an A surface 100', a B surface 200', a C surface 300' and a D surface 400', wherein a rectangular cavity 500' is arranged between the B surface 200', the C surface 300' and the D surface 400', and a mounting notch 600' is arranged between the A surface 100' and the rectangular cavity 500', and the mounting notch 600' is used to fix the photovoltaic panel; and a glue overflow groove 610' is arranged on the surface of the A surface 100' facing the mounting notch 600'. In the photovoltaic frame, since the glue overflow groove 610' is arranged on the A surface 100' with a cantilever structure, the photovoltaic frame is prone to unstable metal flow rate at the position of the glue overflow groove 610' during the extrusion molding process, thereby generating a defect of intermittent scratches in the glue overflow groove 610'. When the photovoltaic frame with such a defect is used, the colloid will flow onto the assembled photovoltaic panel, thereby causing the panel to explode, causing serious economic losses to the supply side and the client. Utility Model Content
[0004] The first purpose of the utility model is to provide a photovoltaic frame to solve the technical problem that the flow rate of metal on the A surface is easily unstable during the extrusion molding process of the existing photovoltaic frame.
[0005] The photovoltaic frame provided by the utility model includes an A surface, a B surface, a C surface and a D surface arranged in sequence, a rectangular cavity is arranged between the B surface, the C surface and the D surface, an installation groove is arranged between the A surface and the rectangular cavity, the installation groove is used to insert a photovoltaic panel, the rectangular cavity has a supporting cavity wall adjacent to the installation groove, and the photovoltaic frame is provided with a glue overflow structure, and the glue overflow structure is arranged on the surface of the supporting cavity wall facing the installation groove.
[0006] Furthermore, the overflow structure includes a plurality of teeth, which are arranged along the insertion direction of the photovoltaic panel, and each of the teeth extends along the length direction of the photovoltaic frame, so that a flow channel for the colloid to overflow is formed between any two adjacent teeth.
[0007] Furthermore, the tooth shape includes a vertical surface and a slope surface set at an angle, wherein the vertical surface is parallel to the B surface, the slope surface is located on the side of the vertical surface away from the B surface, and from the support cavity wall toward the A surface, the slope surface extends obliquely in the direction close to the B surface.
[0008] Furthermore, the angle between the slope surface and the C surface is 45°.
[0009] Furthermore, there is a rounded transition between the vertical surface and the slope surface.
[0010] Furthermore, any two adjacent tooth shapes are closely connected.
[0011] Furthermore, the number of the tooth shapes is not less than 10 and not more than 20.
[0012] Furthermore, the glue overflow structure is arranged close to the opening of the installation slot.
[0013] Furthermore, the photovoltaic frame is made of aluminum alloy.
[0014] The beneficial effects brought by the photovoltaic frame of the utility model are:
[0015] In the photovoltaic frame, the rectangular cavity and the installation slot are separated by the supporting cavity wall of the rectangular cavity, so that the supporting cavity wall serves as both the cavity wall structure of the rectangular cavity and the slot wall structure of the installation slot. By arranging the overflow glue structure on the supporting cavity wall, after the photovoltaic panel is inserted into the installation slot, the excess glue used to bond the photovoltaic panel and the photovoltaic frame can overflow along the overflow glue structure arranged on the supporting cavity wall, so as to prevent the surface of the photovoltaic panel from being contaminated by the glue.
[0016] The photovoltaic frame changes the previous setting position of the overflow glue structure. By setting the overflow glue structure on the supporting cavity wall adjacent to the rectangular cavity and the installation groove, the overflow glue structure is located in a relatively stable structural position in the photovoltaic frame, rather than being set on the A surface of the cantilever structure as before. As a result, the A surface of the photovoltaic frame is a flat plate shape with a simple structure, which simplifies the structure of the A surface in the cantilever state. Furthermore, during the molding process of the photovoltaic frame, the flow rate of the metal used for extrusion molding into the photovoltaic frame is more stable at the A surface position.
[0017] The second purpose of the utility model is to provide a photovoltaic assembly to solve the technical problem that the flow rate of metal on the A surface is easily unstable during the extrusion molding process of the existing photovoltaic frame.
[0018] The photovoltaic assembly provided by the utility model comprises a photovoltaic panel and the above-mentioned photovoltaic frame, wherein the photovoltaic panel is inserted into the installation notch of the photovoltaic frame.
[0019] The beneficial effects brought by the photovoltaic module of the utility model are:
[0020] By providing the above-mentioned photovoltaic frame in the photovoltaic module, the photovoltaic module accordingly has all the advantages of the above-mentioned photovoltaic frame, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0029] Figure 2 The cross-sectional structure diagram of the photovoltaic frame provided in this embodiment. Figure 2 As shown, the present embodiment provides a photovoltaic frame, comprising an A surface 100, a B surface 200, a C surface 300 and a D surface 400 which are arranged in sequence. Specifically, a rectangular cavity 500 is arranged between the B surface 200, the C surface 300 and the D surface 400, and an installation groove 600 is arranged between the A surface 100 and the rectangular cavity 500, and the installation groove 600 is used to insert the photovoltaic panel; the rectangular cavity 500 has a supporting cavity wall 510 adjacent to the installation groove 600, and the photovoltaic frame is provided with a glue overflow structure 610, wherein the glue overflow structure 610 is arranged on the surface of the supporting cavity wall 510 facing the installation groove 600.
[0030] In the photovoltaic frame, the rectangular cavity 500 and the mounting slot 600 are separated by the supporting cavity wall 510 of the rectangular cavity 500, so that the supporting cavity wall 510 serves as both the cavity wall structure of the rectangular cavity 500 and the slot wall structure of the mounting slot 600. By arranging the overflow glue structure 610 on the supporting cavity wall 510, after the photovoltaic panel is inserted into the mounting slot 600, the excess glue used to bond the photovoltaic panel and the photovoltaic frame can overflow along the overflow glue structure 610 arranged on the supporting cavity wall 510, so as to prevent the surface of the photovoltaic panel from being contaminated by the glue.
[0031] The photovoltaic frame changes the previous setting position of the overflow glue structure 610. By setting the overflow glue structure 610 on the supporting cavity wall 510 adjacent to the rectangular cavity 500 and the installation groove 600, the overflow glue structure 610 is located in a relatively stable structural position in the photovoltaic frame, rather than being set on the A surface 100 in a cantilever structure as before. As a result, the A surface 100 of the photovoltaic frame is a flat plate shape with a simple structure, which simplifies the structure of the A surface 100 in a cantilever state. Furthermore, during the molding process of the photovoltaic frame, the flow rate of the metal used for extrusion molding into the photovoltaic frame is more stable at the A surface 100 position.
[0032] In this embodiment, the colloid may be in a liquid form with a certain viscosity.
[0033] Figure 3 for Figure 2 The enlarged view of the local structure at A in the middle. Please continue to refer to Figure 2 , and combined with Figure 3 In this embodiment, the overflow structure 610 may include a plurality of teeth 611. Specifically, the plurality of teeth 611 are arranged along the insertion direction of the photovoltaic panel, and each tooth 611 extends along the length direction of the photovoltaic frame, so that a flow channel 612 for the colloid to overflow is formed between any two adjacent teeth 611.
[0034] It should be noted that Figure 2 In the figure, the direction indicated by the arrow S is the insertion direction of the photovoltaic panel, and the length direction of the photovoltaic frame is the direction perpendicular to the paper surface.
[0035] When the photovoltaic panel and the photovoltaic frame are glued together, excess glue will overflow from the flow channel 612 formed between two adjacent tooth shapes 611 to prevent it from flowing out of the opening of the installation slot 600 and contaminating the photovoltaic panel.
[0036] By setting the overflow glue structure 610 to a plurality of teeth 611, on the one hand, the overflow glue groove with a concave structure is changed into a serrated overflow glue structure 610, which can simplify the structure of the overflow glue structure 610 and make the molding of the overflow glue structure 610 easier, thereby effectively improving the technical problem of the difficulty in molding the overflow glue groove and the intermittent scratch defects in the overflow glue groove in the prior art, which is beneficial to improving the yield of the photovoltaic frame and the service life of the extrusion mold. On the other hand, the plurality of teeth 611 can also be used to increase the surface area of the support cavity wall 510 facing the installation groove 600, thereby increasing the contact area between the colloid and the photovoltaic frame, so as to improve the bonding strength between the colloid and the photovoltaic frame and ensure the installation stability of the photovoltaic panel.
[0037] Please continue to refer to Figure 3 In this embodiment, the tooth shape 611 may include a vertical surface 6111 and a slope surface 6112 set at an angle, wherein the vertical surface 6111 is parallel to the B surface 200, the slope surface 6112 is located on the side of the vertical surface 6111 away from the B surface 200, and from the self-supporting cavity wall 510 to the A surface 100, the slope surface 6112 extends and tilts toward the direction close to the B surface 200.
[0038] The above-mentioned setting of the tooth shape 611 can not only form a flow channel 612 between two adjacent tooth shapes 611 to ensure the reliability of colloid overflow, but also can use the slope surface 6112 to guide the photovoltaic panel inserted into the installation groove 600 to a certain extent, so as to ensure the smooth installation of the photovoltaic panel, thereby improving the assembly efficiency of the photovoltaic panel and the photovoltaic frame.
[0039] Please continue to refer to Figure 3 In this embodiment, the angle between the slope surface 6112 and the C surface 300 is θ, where θ=45°.
[0040] This angle between the slope surface 6112 and the C surface 300 can, on the one hand, avoid the situation where the flow area of the flow channel 612 is too small due to the angle between the slope surface 6112 and the C surface 300 being too small, resulting in a poor overflow effect. On the other hand, it can also avoid the situation where the tooth shape 611 extends too much into the installation slot 600 due to the angle between the slope surface 6112 and the C surface 300 being too large, resulting in a larger size of the B surface 200 when installing photovoltaic panels of the same thickness. That is, the cantilever size of the A surface 100 can be reduced, which is conducive to the compact structural design of the photovoltaic frame.
[0041] It should be noted that in this embodiment, the photovoltaic frame is Figure 2From the perspective, the C-plane 300 is parallel to the horizontal plane, so the angle between the slope surface 6112 and the C-plane 300 can be regarded as Figure 2 The angle between the slope surface 6112 and the horizontal plane under the viewing angle.
[0042] Please continue to refer to Figure 3 In this embodiment, a rounded transition is provided between the vertical surface 6111 and the slope surface 6112 .
[0043] By setting a rounded transition between the vertical surface 6111 and the slope surface 6112, it is possible to avoid forming sharp edges between the vertical surface 6111 and the slope surface 6112 at the connecting position. On the one hand, it can provide certain protection for the operators and prevent them from being scratched. On the other hand, it can also provide certain protection for the photovoltaic panel and prevent the photovoltaic panel from being damaged due to contact with the sharp part of the tooth shape 611 during the process of inserting the photovoltaic panel into the installation slot 600.
[0044] Please continue to refer to Figure 3 In this embodiment, any two adjacent tooth shapes 611 are closely connected. That is, the slope surface 6112 of each tooth shape 611 is connected to the vertical surface 6111 of the tooth shape 611 on the right at the lower end; the vertical surface 6111 of each tooth shape 611 is connected to the slope surface 6112 of the tooth shape 611 on the left at the lower end.
[0045] This form of setting any two adjacent tooth shapes 611 to be closely connected can ensure that the overflow structure 610 has as many tooth shapes 611 as possible while supporting the cavity wall 510 with the same setting width, thereby having as many flow channels 612 as possible to ensure the reliability of colloid overflow.
[0046] It should be noted that, in this embodiment, “the width of the overflow glue structure 610 on the supporting wall” refers to: Figure 2 The dimension of the overflow structure 610 along the left-right direction under the viewing angle.
[0047] Please continue to refer to Figure 2 and Figure 3 In this embodiment, the number of the tooth shapes 611 is no less than 10 and no more than 20.
[0048] By limiting the number of tooth shapes 611 within the above range, on the one hand, it is possible to avoid the situation where the number of flow channels 612 for colloid overflow is too small due to too few tooth shapes 611, and on the other hand, it is possible to avoid the situation where the processing cost is high due to too many tooth shapes 611.
[0049] Please continue to refer to Figure 2 In this embodiment, the overflow glue structure 610 is disposed close to the opening of the mounting notch 600. Figure 2From the perspective of the embodiment, the overflow glue structure 610 is generally disposed at the right half of the supporting cavity wall 510 .
[0050] This form of arranging the overflow glue structure 610 at the opening close to the installation slot 600 makes the overflow glue structure 610 away from the B surface 200, so that the molding of the overflow glue structure 610 is easier.
[0051] In this embodiment, the material of the photovoltaic frame is aluminum alloy. This setting can reduce the weight of the photovoltaic frame.
[0052] Specifically, the material of the photovoltaic frame can be 6005 aluminum alloy.
[0053] In this embodiment, the photovoltaic frame is extruded by an extrusion die, wherein the specific shape of the extrusion die can be designed according to the actual structure of the photovoltaic frame, and the working principle of the extrusion die is the prior art well known to those skilled in the art.
[0054] In addition, this embodiment further provides a photovoltaic assembly, including a photovoltaic panel and the above-mentioned photovoltaic frame, wherein the photovoltaic panel is inserted into the installation slot 600 of the photovoltaic frame.
[0055] By arranging the above-mentioned photovoltaic panel in a photovoltaic module, the photovoltaic module accordingly has all the advantages of the above-mentioned photovoltaic frame, which will not be described one by one here.
[0056] In this embodiment, the number of photovoltaic frames can be four, and the four photovoltaic frames are respectively arranged on the four edges of the photovoltaic panel, so that the four edges of the photovoltaic panel can be respectively inserted into the corresponding photovoltaic frames, and the angle code can be used to realize the connection between any two adjacent photovoltaic frames.
[0057] It should be noted that the specific structure of the angle code and how to use the angle code to achieve the connection between any two adjacent photovoltaic frames can be obtained by those skilled in the art based on the existing technology. This embodiment does not make any improvements on this, so it will not be repeated.
