[0044] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 indicate, according to one embodiment of the present application, the present application proposes a photovoltaic module, comprising: a photovoltaic tile 1; a first connecting piece 2, comprising a first connecting part 20 and a cover plate 22, the first connecting part 20 is connected to one side of the photovoltaic tile 1 along a first direction, the cover plate 22 comprises a body segment 220 and a first extension segment 222, the first connecting part 20, the body segment 220 and the first extension segment 222 are connected in sequence along the first direction; a second connecting piece 3, comprising a second connecting part 30, the second connecting part 30 is connected to the other side of the photovoltaic tile 1 along the first direction, the first connecting piece 2 and the second connecting piece 3 are used for connecting two photovoltaic modules adjacent along the first direction, wherein, in the two adjacent photovoltaic modules, the first connecting piece 2 of one photovoltaic module cooperates with the second connecting piece 3 of the other photovoltaic module, the cover plate 22 can be shielded on one side of the second connecting part 30 along the thickness direction of the photovoltaic tile 1, and in the case that the cooperated first connecting piece 2 and the second connecting piece 3 are in a target assembly state, the cover plate 22 protrudes from the second connecting part 30 along the first direction through the first extension segment 222.

[0045] The photovoltaic module provided by the utility model, including photovoltaic tile 1, first connecting piece 2 and second connecting piece 3, first connecting piece 2 includes first connecting part 20 and cover plate 22, second connecting piece 3 includes second connecting part 30, and first connecting part 20 and second connecting part 30 are connected to the both ends of photovoltaic tile 1 along the first direction respectively. Cover plate 22 includes body section 220 and first extension section 222, and first connecting part 20, body section 220 and first extension section 222 are connected in sequence, and the width of cover plate 22 is increased by the arrangement of first extension section 222, so that, when at least two photovoltaic modules are spliced along the first direction, in the two adjacent photovoltaic modules, the first connecting piece 2 of one photovoltaic module cooperates with the second connecting piece 3 of another photovoltaic module, and the cover plate 22 can be shielded on one side of the second connecting part 30 along the thickness direction of photovoltaic tile 1 to prevent rainwater from flowing into the gap between the two photovoltaic modules, and meanwhile, when the cooperated first connecting piece 2 and second connecting piece 3 are in the target assembly state, the cover plate 22 protrudes from the second connecting part 30 through the first extension section 222, thereby improving the waterproof effect of the gap between the two adjacent photovoltaic modules, in addition, the width of the cover plate 22 is increased by the arrangement of the first extension section 222, thereby increasing the absorbable range of the assembly error between the two adjacent photovoltaic modules, so that when the assembly error between the two adjacent photovoltaic modules is large, the cover plate 22 can also shield the second connecting part 30 of the adjacent photovoltaic module, thereby ensuring the waterproof effect and avoiding the gap between the adjacent photovoltaic modules from being exposed to affect the appearance.

[0046] It can be understood that the photovoltaic tile 1 can convert light energy into electric energy.

[0047] It should be noted that the target assembly state includes normal assembly between adjacent photovoltaic modules, that is, assembly without assembly error or with very small assembly error. In actual application, there may be assembly error between adjacent photovoltaic modules, and the width of the cover plate 22 is increased by the arrangement of the first extension section 222, so that reliable assembly between adjacent photovoltaic modules can be ensured when there is assembly error between adjacent photovoltaic modules, and rainwater can be prevented from entering the lower part of the photovoltaic module.

[0048] Optionally, Figure 6 A view showing that the cooperated first connecting piece 2 and second connecting piece 3 are in the target assembly state is shown, Figure 7 A view showing that the two adjacent photovoltaic modules have up-down (for example, vertical direction) and left-right (for example, first direction) assembly errors is shown.

[0049] Optionally, the cover plate 22 is provided with a limiting rib, the cover plate 22 is arranged close to the upper side of the photovoltaic tile 1 along the thickness direction of the photovoltaic tile 1, the limiting rib is arranged on the lower side of the cover plate 22, and the limiting rib is located between the first connecting part 20 and the second connecting part 30 in the matched first connecting piece 2 and second connecting piece 3. Optionally, the limiting rib is in contact with or has a gap with the second connecting part 30.

[0050] As shown in Figure 6 , in some embodiments, optionally, the width L of the first extension section 222 is greater than or equal to 0.5 times the width d of the second connecting part 30 and less than or equal to 1.5 times the width d of the second connecting part 30.

[0051] In this embodiment, if the width L of the first extension section 222 is too large, the manufacturing cost of the first connecting piece 2 will be increased, the transportation of the product will be affected, and the overall weight of the photovoltaic assembly will be easily increased. If the width L of the first extension section 222 is too small, the absorption effect of the assembly error between adjacent photovoltaic assemblies will be affected. Therefore, the width L of the first extension section 222 is set to be greater than or equal to 0.5 times the width d of the second connecting part 30 and less than or equal to 1.5 times the width d of the second connecting part 30, which can not only ensure the waterproof effect, but also reduce the manufacturing cost and transportation cost.

[0052] Optionally, the width L of the first extension section 222 is any one of 0.5 times, 0.6 times, 0.7 times, 0.8 times, 0.9 times, 1 times, 1.1 times, 1.2 times, 1.3 times, 1.4 times, 1.5 times of the width d of the second connecting part 30, or a value between any two values.

[0053] As shown in Figure 3 , Figure 5 , and Figure 6 , in some embodiments, optionally, the second connecting piece 3 further comprises: a water retaining part 32 connected to one end of the second connecting part 30 away from the photovoltaic tile 1 along the first direction and arranged close to the bottom of the second connecting part 30 along the vertical direction; a second extension section 34 connected to one end of the water retaining part 32 away from the second connecting part 30, the second connecting part 30, the water retaining part 32 and the second extension section 34 enclose a drainage groove 36; and in the target assembly state, one photovoltaic assembly is supported on the second extension section 34 of another photovoltaic assembly by the first connecting part 20.

[0054] In this embodiment, the second connecting piece 3 further comprises a water blocking part 32 and a second extending section 34. The water blocking part 32 is connected with the second connecting part 30, and the second extending section 34 is connected with an end of the water blocking part 32 away from the second connecting part 30, so that the second extending section 34 extends away from the second connecting part 30. When two adjacent photovoltaic components in the target assembly state, the first connecting part 20 of one photovoltaic component is supported on the second extending section 34 of the other photovoltaic component. When there is an assembly error between the two photovoltaic components, there is a gap between the first connecting part 20 of one photovoltaic component and the second extending section 34 of the other photovoltaic component. The second extending section 34 can enclose a drainage groove 36 with the second connecting part 30 and the water blocking part 32, thereby increasing the drainage space and improving the waterproof effect.

[0055] It can be understood that, in the target assembly state, water is drained through the area between the second connecting part 30 and the water blocking part 32. When there is an up-down and / or left-right assembly error between the two adjacent photovoltaic components, the second extending section 34 increases the space of the drainage groove 36, thereby increasing the range of waterproof and improving the waterproof effect.

[0056] Optionally, the second extending section 34 can extend upward, and a water blocking rib can be arranged at the end of the second extending section 34.

[0057] Optionally, the first connecting part 20 is provided with a clamping groove, so that the first connecting part 20 can be clamped to the photovoltaic tile 1. Optionally, the second connecting part 30 is provided with a clamping groove, so that the second connecting part 30 can be clamped to the photovoltaic tile 1.

[0058] It can be understood that, in the two adjacent photovoltaic components, the cover plate 22 blocks the top of the drainage groove 36, thereby achieving at least two levels of waterproof.

[0061] In this embodiment, if the width H of the second extending section 34 is too long, the manufacturing cost will increase. If the width H of the second extending section 34 is too short, the waterproof effect will be weakened. Therefore, the width H of the second extending section 34 is set to be between 10 mm and 50 mm, which can reduce the manufacturing cost and ensure the waterproof effect.

[0062] Optionally, the width H of the second extension segment 34 is any value among 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, and 50mm, or a value between any two of these values.

The water-blocking section 320 is connected between the second connecting part 30 and the boss 322. The second extension section 34 extends from the boss 322 away from the water-blocking section 320. When the first connecting member 2 and the second connecting member 3 are in the target assembly state, the first connecting part 20 contacts or has a gap with the side of the boss 322 away from the second connecting part 30, so that in the target assembly state, a drainage space can be formed between the water-blocking section 320 and the boss 322 to accommodate a certain amount of water and achieve the drainage effect. When there is a certain assembly error between adjacent photovoltaic modules, the setting of the second extension section 34 increases the water-holding space of the drainage groove 36 and further improves the waterproof effect.

[0065] In some embodiments, optionally, at least a portion of the water-blocking section 320 is inclined upward in the vertical direction; and / or at least a portion of the second extension section 34 is inclined upward in the vertical direction; and / or at least a portion of the cover plate 22 is inclined downward in the vertical direction.

[0066] In this embodiment, at least a portion of the water-blocking section 320 is inclined upwards in the vertical direction, so that the water-blocking section 320 and the protrusion 322 can hold more water, preventing water from flowing down to the bottom of the photovoltaic module and improving the waterproof effect. At least a portion of the second extension section 34 is inclined upwards in the vertical direction, so that the drainage channel 36 enclosed by the second extension section 34, the second connecting portion 30, and the water-blocking portion 32 can hold more water, preventing water from flowing down to the bottom of the photovoltaic module and improving the waterproof effect. At least a portion of the cover plate 22 is inclined downwards in the vertical direction, so that rainwater can flow along the cover plate 22 to the upper surface of the photovoltaic tile 1, and then flow away along the installation slope of the photovoltaic tile 1.

[0067] like Figure 1and Figure 5 As shown in some embodiments, optionally, the second extending section 34 is provided with at least one rib 340 extending along the second direction of the photovoltaic tile 1.

[0068] In this embodiment, the second extending section 34 is provided with at least one rib 340, which can block the rainwater flowing away from the water retaining part 32 in the second direction of the second extending section 34, so as to form a water containing space with the second extending section 34, i.e. the provision of the rib 340 can increase the water containing capacity, thereby improving the waterproof effect.

[0069] Optionally, in the case that the number of the ribs 340 on the second extending section 34 is multiple, the multiple ribs 340 are arranged at intervals along the first direction.

[0070] Optionally, the height of the rib 340 protruding from the second extending section 34 is less than the height of the boss 322 protruding from the second extending section 34.

[0071] As shown in some embodiments, optionally, the photovoltaic assembly further comprises a third connecting member 4 arranged at one end of the photovoltaic tile 1 along the second direction, and the third connecting member 4 is used for mounting the photovoltaic assembly on the structure to be mounted 6.

[0072] In this embodiment, the photovoltaic assembly further comprises a third connecting member 4 arranged at one end of the photovoltaic tile 1 along the second direction, so as to mount the photovoltaic assembly on the structure to be mounted 6, thereby improving the mounting reliability of the photovoltaic assembly.

[0073] Optionally, the third connecting member 4 comprises a connecting plate provided with a mounting hole, and the third connecting member 4 is connected with the structure to be mounted 6 through a bolt. Of course, the third connecting member 4 can also be connected with the structure to be mounted 6 through buckling or welding, etc.

[0074] Optionally, the structure to be mounted 6 comprises a batten on a building, etc.

[0075] As shown in some embodiments, optionally, the photovoltaic assembly further comprises a waterproof member 5 arranged at one side of the photovoltaic tile 1 along the thickness direction and close to the third connecting member 4 along the second direction; in two adjacent photovoltaic assemblies along the second direction, a part of the adjacent photovoltaic assembly is overlapped, and the adjacent photovoltaic tiles 1 are in contact through the waterproof member 5. Figure 1 and Figure 2 As shown in some embodiments, optionally, the photovoltaic assembly further comprises a waterproof member 5 arranged at one side of the photovoltaic tile 1 along the thickness direction and close to the third connecting member 4 along the second direction; in two adjacent photovoltaic assemblies along the second direction, a part of the adjacent photovoltaic assembly is overlapped, and the adjacent photovoltaic tiles 1 are in contact through the waterproof member 5.

[0076] In this embodiment, the photovoltaic assembly further comprises a waterproof member 5, when a plurality of photovoltaic assemblies are sequentially overlapped along the second direction, at least part of the photovoltaic assemblies between adjacent photovoltaic assemblies along the second direction are overlapped to avoid rainwater flowing into the gap between adjacent photovoltaic assemblies, and meanwhile, the adjacent photovoltaic tiles 1 are in contact through the waterproof member 5, thereby further improving the waterproof effect.

[0077] Optionally, as shown in Figure 5 and Figure 8 , the photovoltaic assemblies between adjacent photovoltaic assemblies along the second direction are overlapped by a certain distance and are fixed on the structure to be installed 6 by screws, and the water flowing into the drain groove 36 can flow along the arrow direction in Figure 8 to the surface of the adjacent photovoltaic assembly below, and then continue to flow downward.

[0078] It can be understood that the second direction has an angle with the vertical direction, that is, when the photovoltaic assembly is overlapped along the second direction, it is inclined downward along the vertical direction, so that the surface of the photovoltaic assembly forms a slope, thereby facilitating the flow of rainwater.

[0079] Optionally, the waterproof member 5 comprises a waterproof sealing strip, such as a rubber strip, a silica gel strip, etc.

[0080] In some embodiments, optionally, the body segment 220 and the first extension segment 222 are of an integrated structure; and / or the photovoltaic tile 1 comprises a curved tile.

[0085] According to one embodiment of the present application, the width of the cover plate 22 is increased, and the cover plate 22 still covers the drain groove (such as the drain groove 36) when the curved tile (such as the photovoltaic tile 1) moves left and right, which can ensure the appearance after installation and strengthen the waterproof performance. Optionally, the drain groove 36 extends outward to increase the drainage space, which can strengthen the waterproof performance of the system.

[0089] When the photovoltaic module moves left and right, the cover plate 22 of the first frame can absorb a certain construction error, and still meet the appearance requirements and system waterproof requirements, and when the photovoltaic module has an up-down construction error, the second frame has a larger drainage space.

[0090] The adjacent photovoltaic modules in front and back (e.g. along the second direction) are overlapped by a certain distance and are fixed on the keel by screws, and the water leaking into the drainage groove 36 of the second frame can be drained along the slope to the surface of the adjacent photovoltaic module below, and then continue to drain down.
