Description

Technical Field

[0001] This invention belongs to the field of power generation technology, specifically relating to the support structure of photovoltaic modules, and more particularly to a frame for photovoltaic modules, an assembly method, and a photovoltaic module. Background Technology

[0002] During the production of photovoltaic modules, frames need to be installed. In related technologies, the photovoltaic modules are installed by injecting glue into the mounting groove of the frame. However, during the installation process, after the mounting groove is injected with glue, the opening of the mounting groove needs to be turned to one side before installing the photovoltaic module. At this time, the glue in the mounting groove will flow out from the opening, and when the photovoltaic module is inserted into the mounting groove, it will squeeze the glue, causing the glue to overflow from the mounting groove. This results in the glue in the mounting groove dripping onto the production line, causing glue to adhere to the outer wall of the subsequent frames and photovoltaic modules, affecting the quality of the produced photovoltaic modules.

[0003] Therefore, there is a technical problem that arises when adhesive from the mounting groove flows out during the assembly of the frame and photovoltaic module, causing adhesive to drip onto the production line and adhere to the outer walls of the subsequent frame and photovoltaic module, thus affecting the quality of the produced photovoltaic module. This necessitates the design of a frame, assembly method, and photovoltaic module for photovoltaic modules.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0005] This disclosure provides at least one photovoltaic module frame, assembly method, and photovoltaic module.

[0006] In a first aspect, embodiments of this disclosure provide a frame for photovoltaic modules, comprising:

[0007] The frame body has an installation groove, and a blocking mechanism is provided in the installation groove. The blocking mechanism is configured to block the glue in the installation groove after glue is injected into the installation groove and the opening of the installation groove faces one side, and to increase the volume of the installation groove when the photovoltaic module is inserted into the installation groove.

[0008] In one alternative embodiment, the blocking mechanism includes: an arc-shaped plate;

[0009] A groove is formed on one inner wall of the mounting groove perpendicular to its opening, and the arc-shaped plate is disposed in the groove, the arc-shaped plate arching towards the inside of the mounting groove;

[0010] The length of the groove is adapted to the length of the mounting groove, and the length of the arc-shaped plate is adapted to the length of the groove;

[0011] The end of the arc-shaped plate away from the opening of the mounting slot is connected to the inner wall of the groove;

[0012] The arc-shaped plate is elastic;

[0013] When the opening of the mounting groove faces one side, the groove is located on the bottom surface of the mounting groove, and the arched part of the arc plate protrudes out of the groove and extends into the mounting groove.

[0014] In one alternative embodiment, a raised rib is provided on the inner wall of the groove away from the opening, and the raised rib is provided close to the opening of the groove;

[0015] The outer wall of the arc-shaped plate is in contact with the protruding strip;

[0016] The frame body has a guide hole that communicates with the mounting groove. The end of the arc-shaped plate near the opening of the mounting groove extends into the guide hole and is connected to the support plate located outside the mounting groove.

[0017] In one alternative implementation, when installing photovoltaic modules, the opening of the mounting groove faces to one side, at which point the adhesive level in the mounting groove is lower than the highest point of the arched portion of the curved plate, so as to block the adhesive through the curved plate.

[0018] In one alternative implementation, when the photovoltaic module is inserted into the mounting groove, the opening of the mounting groove faces to one side. The photovoltaic module presses against the arc-shaped plate, causing the arc-shaped plate to be compressed into the groove, thus separating the arc-shaped plate from the convex strip. The area enclosed by the convex strip, the groove, and the arc-shaped plate is connected to the mounting groove, increasing the volume of the mounting groove. The support plate extends away from the mounting groove to support the photovoltaic module.

[0019] In one alternative implementation, adhesive is injected into the mounting slot when the opening of the mounting slot is facing upwards.

[0020] Secondly, this disclosure also provides an assembly method using the above-described photovoltaic module frame, comprising:

[0021] After the adhesive is injected into the mounting groove and the opening of the mounting groove faces one side, the blocking mechanism blocks the adhesive in the mounting groove and increases the volume of the mounting groove when the photovoltaic module is installed into the mounting groove.

[0022] In one alternative implementation, when installing photovoltaic modules, the opening of the mounting groove faces to one side, at which point the adhesive level in the mounting groove is lower than the highest point of the arched portion of the curved plate, so as to block the adhesive through the curved plate.

[0023] In one alternative implementation, when the photovoltaic module is installed into the mounting groove, the opening of the mounting groove faces to one side. The photovoltaic module squeezes the arc plate, causing the arc plate to be compressed into the groove, so that the arc plate separates from the convex strip. The area enclosed by the convex strip, the groove and the arc plate is connected to the mounting groove, increasing the volume of the mounting groove. The support plate extends away from the mounting groove to support the photovoltaic module.

[0024] In one alternative implementation, adhesive is injected into the mounting slot when the opening of the mounting slot is facing upwards.

[0025] Thirdly, embodiments of this disclosure also provide a photovoltaic module, comprising:

[0026] A photovoltaic module, wherein a portion of the photovoltaic module is mounted within the aforementioned photovoltaic module frame.

[0027] The beneficial effects of this invention are that the photovoltaic module frame includes: a frame body having an installation groove thereon, and a blocking mechanism provided in the installation groove. The blocking mechanism is configured to block the glue in the installation groove after glue is injected into the installation groove and the opening of the installation groove faces one side, and to increase the volume of the installation groove when the photovoltaic module is inserted into the installation groove, thereby preventing the glue in the installation groove from flowing out.

Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment.

[0041] During the production of photovoltaic modules, frames need to be installed. In related technologies, the photovoltaic modules are installed by injecting glue into the mounting groove of the frame. However, during the installation process, after the mounting groove is injected with glue, the opening of the mounting groove needs to be turned to one side before installing the photovoltaic module. At this time, the glue in the mounting groove will flow out from the opening, and when the photovoltaic module is inserted into the mounting groove, it will squeeze the glue, causing the glue to overflow from the mounting groove. This results in the glue in the mounting groove dripping onto the production line, causing glue to adhere to the outer wall of the subsequent frames and photovoltaic modules, affecting the quality of the produced photovoltaic modules.

[0042] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] like Figure 1 As shown, at least one disclosed embodiment provides a frame for a photovoltaic module, including: a frame body 1, on which a mounting groove 11 is provided, and a blocking mechanism 2 is provided in the mounting groove 11. The blocking mechanism 2 is configured to block the glue in the mounting groove 11 after glue is injected into the mounting groove 11 and the opening of the mounting groove 11 faces one side, and to increase the volume of the mounting groove 11 when the photovoltaic module is inserted into the mounting groove 11, thereby preventing the glue in the mounting groove 11 from flowing out and preventing the glue from dripping onto the production line, thereby preventing the subsequent frame body 1 and photovoltaic module from adhering to the glue dripping onto the production line, and ensuring the quality of the photovoltaic module.

[0046] In this embodiment, after the glue is injected into the mounting groove 11, the frame body 1 can be assembled with the photovoltaic module.

[0047] like Figure 2 As shown, in an optional embodiment, the blocking mechanism 2 includes: an arc-shaped plate 21; a groove 12 is formed on an inner wall of the mounting groove 11 perpendicular to its opening, the arc-shaped plate 21 is disposed in the groove 12, and the arc-shaped plate 21 arches towards the inside of the mounting groove 11; one end of the arc-shaped plate 21 away from the opening of the mounting groove 11 is connected to the inner wall of the groove 12; the arc-shaped plate 21 is elastic; when the opening of the mounting groove 11 faces to one side, the groove 12 is located on the inner bottom surface of the mounting groove 11, and the arched part of the arc-shaped plate 21 protrudes from the groove 12 and extends into the mounting groove 11.

[0048] In this embodiment, the length of the groove 12 is adapted to the length of the mounting groove 11, and the length of the arc plate 21 is adapted to the length of the groove 12, so that when the mounting groove 11 is open to one side, the arc plate 21 can completely block the glue and prevent the glue from flowing out.

[0049] In this embodiment, the arc-shaped plate 21 contacts the inner walls of the mounting grooves 11 on both sides to better block the glue.

[0050] In this embodiment, in the initial state, the photovoltaic module has not yet been assembled with the frame body 1. At this time, the arc plate 21 protrudes from the groove 12 and extends into the mounting groove 11.

[0051] In this embodiment, when assembling the frame body 1 with the photovoltaic module, the frame body 1 is rotated so that the mounting groove 11, which was originally open and facing upwards, is rotated to open and facing one side. At this time, the groove 12 is located on the inner bottom surface of the mounting groove 11 in the current state, and the glue level in the mounting groove 11 is lower than the highest point of the arched part of the arc plate 21, so as to block the glue through the arc plate 21 and prevent the glue from flowing out of the mounting groove 11.

[0052] like Figure 2 As shown, in an optional embodiment, the inner wall of the groove 12 away from the opening is provided with a protrusion 13, and the protrusion 13 is provided close to the opening of the groove 12; the outer wall of the arc plate 21 contacts the protrusion 13; the frame body 1 is provided with a guide hole 14 communicating with the mounting groove 11, and one end of the arc plate 21 near the opening of the mounting groove 11 extends into the guide hole 14 and is connected to the support plate 22 located outside the mounting groove 11.

[0053] In this embodiment, when a portion of the photovoltaic module has not yet extended into the mounting groove 11, the protrusion 13 contacts the arc plate 21 to separate the groove 12 from the mounting groove 11.

[0054] In this embodiment, the length of the protrusion 13 can be the same as the length of the arc plate 21.

[0055] In this embodiment, when the photovoltaic module is partially inserted into the mounting groove 11 to complete the assembly of the photovoltaic module and the frame body 1, the photovoltaic module portion inserted into the mounting groove 11 will squeeze the arc plate 21, pressing the arc plate 21 into the groove 12, so that the arc plate 21 no longer contacts the protrusion 13, and the area enclosed by the protrusion 13, the groove 12 and the arc plate 21 are connected to the mounting groove 11, and some glue can enter the groove 12, avoiding the glue in the mounting groove 11 from being squeezed out of the mounting groove 11 because the photovoltaic module portion is inserted into the mounting groove 11.

[0056] In this embodiment, the area enclosed by the protrusion 13, the groove 12 and the arc plate 21 is connected to the mounting groove 11, so that when the adhesive in the mounting groove 11 is squeezed by the photovoltaic module, some of the adhesive can enter the area enclosed by the protrusion 13, the groove 12 and the arc plate 21, thus preventing the adhesive from overflowing.

[0057] like Figure 3 As shown, in an optional embodiment, glue is injected into the mounting groove 11 when the opening of the mounting groove 11 is facing upward.

[0058] like Figure 4As shown, in an optional embodiment, when installing photovoltaic modules, the opening of the mounting groove 11 faces to one side, and the glue level in the mounting groove 11 is lower than the highest point of the arched portion of the arc plate 21, so as to block the glue through the arc plate 21.

[0059] like Figure 5 As shown, in one optional embodiment, when the photovoltaic module is inserted into the mounting groove 11, the opening of the mounting groove 11 faces to one side. The photovoltaic module squeezes the arc plate 21, causing the arc plate 21 to be compressed into the groove 12, so that the arc plate 21 is separated from the ridge 13. The area enclosed by the ridge 13, the inner wall of the groove 12 and the top surface of the arc plate 21 is connected to the mounting groove 11, increasing the volume of the mounting groove 11. The support plate 22 extends away from the mounting groove 11 to support the photovoltaic module.

[0060] In this embodiment, when part of the photovoltaic module extends into the mounting groove 11, it presses the arc plate 21, causing the arc plate 21 to be pressed into the groove 12. The end of the arc plate 21 near the opening of the mounting groove 11 moves in the guide hole 14, allowing the support plate 22 to extend away from the mounting groove 11. The support plate 22 supports the back of the photovoltaic module, thus supporting the photovoltaic module.

[0061] At least one other disclosed embodiment also provides an assembly method using the above-described photovoltaic module frame, comprising: after injecting adhesive into the mounting groove 11 and with the opening of the mounting groove 11 facing one side, blocking the adhesive in the mounting groove 11 by a blocking mechanism 2, and increasing the volume of the mounting groove 11 when the photovoltaic module is installed into the mounting groove 11.

[0062] In one alternative embodiment, when installing photovoltaic modules, the opening of the mounting groove 11 faces to one side, and the level of adhesive in the mounting groove 11 is lower than the highest point of the arched portion of the arc plate 21, so as to block the adhesive through the arc plate 21.

[0063] In one alternative embodiment, when the photovoltaic module is installed into the mounting groove 11, the opening of the mounting groove 11 faces one side. The photovoltaic module presses the arc plate 21, causing the arc plate 21 to be compressed into the groove 12, so that the arc plate 21 is separated from the ridge 13. The area enclosed by the ridge 13, the groove 12 and the arc plate 21 is connected to the mounting groove 11, increasing the volume of the mounting groove 11. The support plate 22 extends away from the mounting groove 11 to support the photovoltaic module.

[0064] At least one other disclosed embodiment also provides a photovoltaic module, including: a photovoltaic module, a portion of which is mounted within the aforementioned photovoltaic module frame.

[0065] In summary, the photovoltaic module frame includes: a frame body 1, on which a mounting groove 11 is provided, and a blocking mechanism 2 is provided in the mounting groove 11. The blocking mechanism 2 is configured to block the glue in the mounting groove 11 after glue is injected into the mounting groove 11 and the opening of the mounting groove 11 faces one side, and to increase the volume of the mounting groove 11 when the photovoltaic module is inserted into the mounting groove 11, thereby preventing the glue in the mounting groove 11 from flowing out.
