[0029] Refer to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a photovoltaic tile in a photovoltaic tile assembly provided by an embodiment of the present utility model. Figure 2 is a partial sectional view of the cooperation of adjacent photovoltaic tiles in a photovoltaic tile assembly provided by an embodiment of the present utility model. An embodiment of the present utility model provides a photovoltaic tile assembly, including a waterproof assembly 200 and at least two photovoltaic tiles 100; at least two photovoltaic tiles 100, the photovoltaic tile 100 includes a surface layer glass 110, a battery cell 120 and a support plate 130 arranged in sequence; the surface layer glass 110 and the support plate 130 are arranged in a staggered manner in a first direction, so that the surface layer glass 110 on one side of the photovoltaic tile 100 protrudes to form an upper overlapping edge 140, and the support plate 130 on the other side of the photovoltaic tile 100 protrudes to form a lower overlapping edge 150. Among any two adjacent photovoltaic tiles 100 in the first direction, the upper overlapping edge 140 overlaps with the lower overlapping edge 150, where the first direction coincides with the width direction or the length direction of the photovoltaic tile 100; the waterproof assembly 200 is arranged between the upper overlapping edge 140 and the lower overlapping edge 150 of any two adjacent photovoltaic tiles 100, and is respectively in contact with the corresponding upper overlapping edge 140 and lower overlapping edge 150 to seal the gap between the corresponding upper overlapping edge 140 and lower overlapping edge 150.
[0030] Specifically, in the present application, a waterproof component 200 is provided between the upper overlapping edge 140 and the lower overlapping edge 150, and the waterproof component 200 is respectively in contact with the corresponding upper overlapping edge 140 and the lower overlapping edge 150, thereby sealing the gap between the corresponding upper overlapping edge 140 and the lower overlapping edge 150 and improving the waterproof performance of the photovoltaic tile assembly.
[0031] It should be noted that the surface layer glass 110 is located above the support plate 130. In this embodiment, the support plate 130 can be a glass plate or a back plate.
[0032] Refer to Figure 1 and Figure 2 , in one of the embodiments, the waterproof component 200 is connected to the side of the upper overlapping edge 140 facing the lower overlapping edge 150.
[0033] Specifically, the surface layer glass 110 is located above the support plate 130, and the waterproof component 200 is connected to the side of the upper overlapping edge 140 facing the lower overlapping edge 150, so that the surface layer glass 110 can cover the connection between the waterproof component 200 and the upper overlapping edge 140, avoiding being drenched by rainwater and also avoiding the soaking of rainwater, thereby improving the stability of the connection between the waterproof component 200 and the upper overlapping edge 140.
[0034] Refer to Figure 1 and Figure 2 , in one of the embodiments, the waterproof component 200 includes a restraint block 220 and a waterproof rubber strip 210. One end of the waterproof rubber strip 210 is installed on the restraint block 220, and the other end of the waterproof rubber strip 210 extends between the corresponding upper overlapping edge 140 and the lower overlapping edge 150 and is respectively in contact with the corresponding upper overlapping edge 140 and the lower overlapping edge 150. The restraint block 220 is connected to the corresponding upper overlapping edge 140 and is located between two adjacent support plates 130.
[0035] Specifically, the restraint block 220 is located between two adjacent support plates 130, so that the connection between the restraint block 220 and the upper overlapping edge 140 is located inside the waterproof rubber strip 210, and the gap between the upper overlapping edge 140 and the lower overlapping edge 150 is sealed by the waterproof rubber strip 210, thereby preventing rainwater from being introduced into the connection between the restraint block 220 and the upper overlapping edge 140 through the gap between the corresponding upper overlapping edge 140 and the lower overlapping edge 150 and improving the stability of the connection between the restraint block 220 and the upper overlapping edge 140.
[0036] Among them, when the corresponding upper overlapping edge 140 and the lower overlapping edge 150 overlap, the upper overlapping edge 140 and the lower overlapping edge 150 can squeeze the waterproof rubber strip 210 to cause elastic deformation. Since the constraint block 220 is located between two adjacent support plates 130, the constraint block 220 can be prevented from abutting against the lower overlapping edge 150, so as to interfere with the elastic deformation of the waterproof rubber strip 210, and the reliability of the waterproof performance of the photovoltaic tile assembly is improved.
[0037] Refer to Figure 1 and Figure 2 In one embodiment, the waterproof rubber strip 210 includes a clamping portion 211. The clamping portion 211 is located between the corresponding upper overlapping edge 140 and the lower overlapping edge 150. At least two first protruding portions 212 are arranged on the clamping portion 211 at intervals in the first direction. The first protruding portions 212 are used to abut against the corresponding upper overlapping edge 140 or the lower overlapping edge 150.
[0038] Specifically, at least two first protruding portions 212 are arranged on the upper side of the clamping portion 211 at intervals in the first direction. Each first protruding portion 212 abuts against the side of the upper overlapping edge 140 facing the lower overlapping edge 150, so that the clamping portion 211 and the upper overlapping edge 140 form a multi-layer seal, improving the waterproof performance. Preferably, a plurality of first protruding portions 212 are arranged on the upper side of the clamping portion 211 at intervals in the first direction.
[0039] At least two first protruding portions 212 are arranged on the lower side of the clamping portion 211 at intervals in the first direction. Each first protruding portion 212 abuts against the side of the lower overlapping edge 150 facing the upper overlapping edge 140, so that the clamping portion 211 and the lower overlapping edge 150 form a multi-layer seal, improving the waterproof performance. Preferably, a plurality of first protruding portions 212 are arranged on the lower side of the clamping portion 211 at intervals in the first direction.
[0040] Among them, there is a groove between any adjacent first protruding portions 212, so as to provide a deformation space for the elastic deformation when the first protruding portion 212 abuts against the upper overlapping edge 140 or the lower overlapping edge 150, making the clamping portion 211 abut more closely against the upper overlapping edge 140 and the lower overlapping edge 150. Preferably, the first protruding portion 212 is semicircular.
[0041] Refer to Figure 1 and Figure 2 In one embodiment, the waterproof rubber strip 210 further includes a diversion strip 213. The diversion strip 213 is connected to one end of the clamping portion 211 away from the constraint block 220 and extends outward to abut against the area of the lower overlapping edge 150 outside the upper overlapping edge 140. In the direction away from the constraint block 220, the distance between the diversion strip 213 and the lower overlapping edge 150 decreases.
[0042] Specifically, the diversion strip 213 is connected to one end of the clamping portion 211 away from the restraint block 220 and extends outward. In the direction away from the restraint block 220, the distance between the diversion strip 213 and the lower overlapping edge 150 is reduced, so as to have a diversion effect on rainwater, and can divert the rainwater to one side away from the gap between the corresponding upper overlapping edge 140 and the lower overlapping edge 150, thereby improving the waterproof performance. Among them, the abutment of the diversion strip 213 and the lower overlapping edge 150 in the area outside the upper overlapping edge 140 can further play a sealing role and improve the waterproof performance.
[0043] Refer to Figure 1 and Figure 2 , in one embodiment, the waterproof rubber strip 210 includes an abutting portion 214. The abutting portion 214 is located between the restraint block 220 and the lower overlapping edge 150 and abuts against the corresponding restraint block 220 and the lower overlapping edge 150 to seal the gap between the corresponding restraint block 220 and the lower overlapping edge 150.
[0044] Specifically, the restraint block 220 extends between two adjacent support plates 130. The abutting portion 214 is connected to the clamping portion 211 and is located below the clamping portion 211. Since the abutting portion 214 is located between the restraint block 220 and the lower overlapping edge 150, when the upper overlapping edge 140 and the lower overlapping edge 150 are overlapped, the lower overlapping edge 150 can cooperate with the restraint block 220 to clamp the abutting portion 214, thereby improving the sealing performance of the gap between the lower overlapping edge 150 and the restraint block 220. That is, in this application, the clamping portion 211 abuts against the side of the lower overlapping edge 150 facing the upper overlapping edge 140, and the abutting portion 214 abuts against the side of the lower overlapping edge 150 facing the restraint member, so as to perform double-layer sealing and further improve the waterproof performance.
[0045] Furthermore, there is a gap between the restraint block 220 and the corresponding battery cell 120 bracket, which can reduce the interference with the battery cell 120 and can also play a role in heat dissipation.
[0046] Refer to Figure 1 and Figure 2 , in one embodiment, at least two second protrusions 215 are provided on the side of the abutting portion 214 facing away from the restraint block 220 and are spaced apart in the thickness direction of the photovoltaic tile 100. The second protrusions 215 are used to abut against the lower overlapping edge 150.
[0047] Specifically, each second protrusion 215 abuts against the side of the lower overlapping edge 150 facing the restraint block 220, so as to form a multi-layer seal with the lower overlapping edge 150 and improve the waterproof performance between the restraint block 220 and the lower overlapping edge 150.
[0048] There is a groove between any adjacent second protrusions 215, so as to provide deformation space for the elastic deformation of the second protrusion 215 against the lower overlap edge 150, so that the abutment portion 214 abuts more tightly with the constraint block 220 and the lower overlap edge 150. Preferably, the second protrusion 215 is semicircular.
[0049] See also Figure 1 and Figure 2 In one embodiment, a snap-in groove 221 is provided on the constraint block 220, and the waterproof rubber strip 210 includes a mounting portion 216, and the mounting portion 216 has a cavity 217. The cavity 217 is configured to deform when the mounting portion 216 is inserted into the snap-in groove 221, so that the mounting portion 216 abuts against the groove wall of the snap-in groove 221.
[0050] Specifically, the mounting portion 216 is connected to the clamping portion 211, and the mounting portion 216 has a cavity 217, so that the elastic deformation degree of the mounting portion 216 can be improved, which facilitates the mounting portion 216 to extend into the snap-in groove 221, and by restoring the deformation, the mounting portion 216 can abut against the groove wall of the snap-in groove 221, thereby improving the stability of the plug-in fit between the mounting portion 216 and the snap-in groove 221.
[0051] Furthermore, a side of the mounting portion 216 facing away from the clamping portion 211 has an inclined introduction surface 218 , so as to facilitate the mounting portion 216 to extend into the clamping groove 221 .
[0052] See also Figure 1 and Figure 2 In one embodiment, the photovoltaic tile assembly further includes an adhesive film 230 , and the restraining block 220 is connected to the upper overlapping edge 140 via the adhesive film 230 .
[0053] Specifically, the restraining part is made of metal. In this embodiment, ultrasonic welding or laser welding is used to hot-melt the adhesive film 230 , and then the restraining part and the adhesive film 230 that solidifies after hot melting are connected to the upper overlapping edge 140 to improve the stability of the connection between the restraining part and the upper overlapping edge 140 .
[0054] See also Figure 1 and Figure 3 , Figure 3 A partial cross-sectional view of the cooperation of adjacent photovoltaic tiles in a photovoltaic tile assembly provided by another embodiment of the utility model. In one embodiment, the upper overlap edge 140 has a glue injection hole 160, and the glue injection hole 160 is used to accommodate the glue 240 so that the restraint block 220 is bonded to the upper overlap edge 140 through the glue 240.
[0055] Specifically, the glue injection hole 160 is aligned with the constraint member in the thickness direction of the photovoltaic tile 100. The provision of the glue injection hole 160 enables the constraint block 220 to be bonded to the upper overlapping edge 140 through more adhesive 240, improving the bonding stability between the constraint block 220 and the upper overlapping edge 140.
[0056] Furthermore, a partial area of the constraint member is located outside the glue injection hole 160, increasing the bonding area between the constraint member and the upper overlapping edge 140 and improving the bonding stability between the constraint block 220 and the upper overlapping edge 140.
[0057] 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 described in this specification.
[0058] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof 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 utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
