[0029] Refer to Figure 1 , Figure 1 FIG. 1 is a first schematic diagram of an anti-dust accumulation photovoltaic module provided by an embodiment of the present utility model. An anti-dust accumulation photovoltaic module provided by an embodiment of the present utility model includes a laminate 100 and a frame 200. The laminate 100 includes a front glass 110, solar cells 120 and a support plate 130 arranged in sequence. The edge of the front glass 110 protrudes relative to the support plate 130. The frame 200 has a support surface 220. The support surface 220 is bonded to the side of the support plate 130 facing away from the front glass 110 through an adhesive 300. A support platform 230 protrudes from the support surface 220. The support platform 230 is bonded to the side of the front glass 110 facing the support plate 130 through the adhesive 300. A groove 231 is provided on the support platform 230. The notch of the groove 231 is located on the side facing the front glass 110. The groove 231 is used for storing the adhesive 300.

[0030] Specifically, in the present application, the edge of the front glass 110 protrudes from the support plate 130, so that the front glass 110 can be bonded to the support table 230, and the support plate 130 can be bonded to the support surface 220. As a result, while the laminate 100 is connected to the frame 200, the side of the front glass 110 facing away from the support plate 130 can be exposed outside the frame 200, facilitating the cleaning of the dust on the laminate 100 by rainwater. The provision of the groove 231 on the support table 230 enables more adhesive 300 to be stored between the front glass 110 and the support table 230, thereby improving the bonding stability between the front glass 110 and the support table 230 and enhancing the wind resistance of the laminate 100.

[0031] Furthermore, the frame 200 includes a main body 210, and the support surface 220 is provided on the main body 210. The main body 210 is used to connect to the bracket to fix the laminate 100. Among them, the support plate 130 can be a glass plate. In other embodiments, it can also be a back plate or the like.

[0032] Refer to Figure 1 , in one embodiment, the support table 230 includes a first boss 232 and a second boss 233. The first boss 232 and the second boss 233 are spaced apart along the width direction of the frame 200. The groove 231 is located between the first boss 232 and the second boss 233. The second boss 233 is located on the side closer to the middle position of the laminate 100, and the height of the second boss 233 is lower than that of the first boss 232.

[0033] Specifically, when injecting glue, generally, the glue injection starts from the edge between the laminate 100 and the frame 200, that is, from the side of the first boss 232 facing away from the second boss 233. Then, the adhesive 300 will flow into the groove 231 along the gap between the first boss 232 and the front glass 110 for storage. Since the height of the second boss 233 is lower than that of the first boss 232, when the adhesive 300 in the groove 231 reaches a certain height, the adhesive 300 can overflow the second boss 233, facilitating the overflow of the adhesive 300 in the groove 231 into the gap between the second boss 233 and the front glass 110 and flowing along the side wall of the second boss 233 to the gap between the support surface 220 and the support plate 130 to ensure the stable connection between the support plate 130 and the support surface 220.

[0034] It should be noted that if the height of the second boss 233 is greater than or equal to the height of the second boss 233, when the height of the rubber compound 300 stored in the groove 231 is flush with the height of the first boss 232, there will be problems with difficult injection of the rubber compound 300, resulting in low injection efficiency. Moreover, it is not convenient for the rubber compound 300 to overflow into the gap between the second boss 233 and the front glass 110 through the second boss 233, which affects the amount of stored rubber compound in the gap between the second boss 233 and the front glass 110, and further affects the connection stability between the front glass 110 and the second boss 233.

[0035] Refer to Figure 1 , in one embodiment, a guiding wall 234 is provided on the side of the first boss 232 away from the second boss 233. In the direction from the second boss 233 to the first boss 232, the distance between the guiding wall 234 and the front glass 110 gradually increases, thus facilitating glue injection and improving the reliability of the dust-proof photovoltaic module.

[0036] Furthermore, the edge of the second boss 233 facing the front glass 110 is chamfered, so as to facilitate the rubber compound 300 to overflow along the side wall of the second boss 233 into the space between the support surface 220 and the support plate 130. Among them, the edge of the first boss 232 close to the second boss 233 is also chamfered.

[0037] Refer to Figure 1 and Figure 2 , Figure 2 is the second schematic diagram of the dust-proof photovoltaic module provided by an embodiment of the present invention. In one embodiment, the dust-proof photovoltaic module further includes a retaining strip 400. The retaining strip 400 is located on the side of the support platform 230 away from the middle position of the lamination 100, and one side of the retaining strip 400 abuts against the support plate 130, and the other side abuts against the support surface 220.

[0038] Specifically, the retaining strip 400 can play a role in supporting the front glass 110. At the same time, the retaining strip 400 can play a role in preventing glue overflow, so that more rubber compound 300 can be stored in the gap between the first boss 232 and the front glass 110, so as to improve the bonding stability between the front glass 110 and the first boss 232.

[0039] Refer to Figure 1 and Figure 2 , in one embodiment, the retaining strip 400 abuts against the support platform 230, thereby reducing the gap between the retaining strip 400 and the first boss 232, so that the rubber compound 300 is stored as much as possible in the gap between the first boss 232 and the front glass 110, and the bonding stability between the front glass 110 and the first boss 232 is improved.

[0040] Refer to Figure 1 and Figure 2, in one embodiment, the side of the retaining bar 400 facing away from the support platform 230 is flush with the front glass 110, which can avoid the edge of the front glass 110 protruding relative to the retaining bar 400, thereby protecting the front glass 110 and improving the reliability of the dust-proof photovoltaic module.

[0041] Refer to Figure 1 , Figure 2 and Figure 3 , Figure 3 FIG.

[0042] Refer to Figure 1 , Figure 2 and Figure 3 , in one embodiment, a first receiving groove 235 is provided on the side wall of the support platform 230. The notch of the first receiving groove 235 faces the battery cell 120, and the first receiving groove 235 is used to receive the adhesive 300.

[0043] Specifically, the first receiving groove 235 is provided on the side of the second boss 233 facing away from the first boss 232. The first receiving groove 235 can receive the adhesive 300, so that more adhesive 300 can be stored between the second boss 233 and the battery cell 120 and the support plate 130, thereby improving the connection stability between the second boss 233 and the battery cell 120 and the support plate 130.

[0044] Refer to Figure 1 , Figure 2 and Figure 3 , in one embodiment, a second receiving groove 221 is provided on the support surface 220. The notch of the second receiving groove 221 faces the support plate 130, and the second receiving groove 221 is used to receive the adhesive 300.

[0045] Specifically, the second receiving groove 221 can receive the adhesive 300, so that more adhesive 300 can be stored between the support surface 220 and the support plate 130, thereby improving the connection stability between the support surface 220 and the support plate 130.

[0046] Refer to Figure 1 , Figure 2 and Figure 3 , in one embodiment, the first receiving groove 235 is communicated with the second receiving groove 221, so that the adhesive 300 flowing into the first receiving groove 235 through the side wall of the second boss 233 can flow into the second receiving groove 221, improving the glue injection efficiency.

[0047] Furthermore, the notch of the first receiving groove 235 partially overlaps with the notch of the second receiving groove 221, facilitating the flow of the rubber compound 300 and improving the glue injection efficiency.

[0048] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0049] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
