[0037] In the description of this application, the descriptions with reference to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0038] Referring to Figures 1 to 3 , according to the solar power supply device of the first aspect embodiment of this application, it includes: a base body 100, a photovoltaic module 200, a first connector 300, a second connector 400, and an ammeter 500. One end of the first connector 300 is connected to the photovoltaic module 200; the second connector 400 includes a first connecting portion 410, a second connecting portion 420, and a third connecting portion 430 that are connected in sequence. The first connecting portion 410 is rotatably connected to the first connector 300, and the third connecting portion 430 is rotatably connected to the base body 100; wherein, the axis line of the first connecting portion 410 intersects with the axis line of the third connecting portion 430. Specifically, the axis line of the first connecting portion 410 is perpendicular to the axis line of the third connecting portion 430; the ammeter 500 is fixedly connected to the photovoltaic module 200 and is electrically connected to the photovoltaic module 200.

[0039] It can be understood that the base body 100 is used for fixedly connecting with a wall or other building carriers to fixedly arrange the solar power supply device of this application.

[0040] It can be understood that the photovoltaic module 200 is used for obtaining solar energy and converting solar energy into electrical energy.

[0041] It can be understood that the first connecting member 300 can rotate relative to the first connecting portion 410 about the axis line of the first connecting portion 410, and the third connecting portion 430 can rotate relative to the base body 100 about the axis line of the third connecting portion 430. When the first connecting member 300 rotates relative to the first connecting portion 410 or the base body 100 rotates relative to the third connecting portion 430, the photovoltaic module 200 can be driven to rotate, thereby changing the orientation of the photovoltaic module 200. Since the axis lines of the first connecting portion 410 and the third connecting portion 430 intersect, the rotation direction of the first connecting member 300 relative to the first connecting portion 410 is different from the rotation direction of the third connecting portion 430 relative to the base body 100. Thus, the photovoltaic module 200 connected to the first connecting member 300 can have at least two rotation directions, so as to better adjust the orientation of the photovoltaic module 200.

[0042] It can be understood that the ammeter 500 is electrically connected to the photovoltaic module 200. After the photovoltaic module 200 converts solar energy into electrical energy, the ammeter 500 can obtain the magnitude of the current to determine whether the current orientation of the photovoltaic module 200 is beneficial to the photovoltaic module 200 for obtaining solar energy, and can rotate in cooperation with the first connecting member 300 and the base body 100 respectively through the second connecting member 400 to rotate the photovoltaic module 200 to the optimal orientation, so that the photovoltaic module 200 can better obtain solar energy and improve the energy supply effect of the photovoltaic module 200. For example, when the current reading obtained by the ammeter 500 is small, it indicates that the orientation of the photovoltaic module 200 is not good, and the orientation of the photovoltaic module 200 can be adjusted by rotating the first connecting member 300 or the second connecting member 400, so that the reading of the ammeter 500 is large, thereby confirming the optimal orientation of the photovoltaic module 200.

[0043] It should be understood that the position of the sun changes during a day. Thus, during the process of adjusting the orientation of the photovoltaic module 200, it may only be the current optimal orientation. To ensure the power supply effect of the photovoltaic module 200, in some embodiments, the orientation of the photovoltaic module 200 can be manually adjusted at different time periods to ensure that the orientation of the photovoltaic module 200 is optimal in each time period; in some other embodiments, the orientation of the photovoltaic module 200 can be determined according to the time period with the most sufficient sunlight to ensure that the orientation of the photovoltaic module 200 is optimal during the time period with the most sufficient sunlight; in some other embodiments, the orientation with the same or similar time periods among the optimal orientations of the photovoltaic module 200 in each time period can be selected as the orientation of the photovoltaic module 200; in some other embodiments, driving members can be respectively arranged inside the first connecting member 300 and the second connecting member 400. The driving members drive the first connecting member 300 to rotate relative to the second connecting member 400, and drive the second connecting member 400 to rotate relative to the base body 100. Moreover, the driving members are connected to the ammeter 500. The driving members can drive the first connecting member 300 and / or the second driving member according to the reading of the ammeter 500 to automatically adjust the orientation of the photovoltaic module 200, so that the photovoltaic module 200 always maintains the optimal orientation.

[0044] Specifically, the first connecting portion 410, the second connecting portion 420 and the third connecting portion 430 are integrally formed.

[0045] Referring to Figure 3 、 Figure 5 and Figure 6 According to some embodiments of the present application, the base body 100 is provided with an installation hole 110. The third connecting portion 430 is rotatably inserted into the installation hole 110. A first clamping structure 431 is arranged at one end of the third connecting portion 430 away from the second connecting portion 420. The first clamping structure 431 is formed with a first guiding surface 4311 and a first limiting surface 4312. The first guiding surface 4311 is used for sliding cooperation with the inner wall of the installation hole 110 to guide the third connecting portion 430 to pass through the installation hole 110. The first limiting surface 4312 is used for abutting against one side of the base body 100 away from the second connecting portion 420 to limit the third connecting portion 430 from disengaging from the installation hole 110.

[0046] It can be understood that the third connecting portion 430 can rotate within the mounting hole 110, thereby achieving the rotational fit between the third connecting portion 430 and the base body 100. The snap fit between the third connecting portion 430 and the base body 100 is achieved by providing a first snap structure 431 on the third connecting portion 430. Specifically, during the process of inserting the third connecting portion 430 into the mounting hole 110, the first guiding surface 4311 of the first snap structure 431 can slide in cooperation with the inner wall of the mounting hole 110 to guide the third connecting portion 430 through the mounting hole 110. It should be understood that the first snap structure 431 has a certain plasticity and can be deformed under the action of an external force. The first guiding surface 4311 is inclined such that the dimension of the end of the first snap structure 431 away from the second connecting portion 420 is larger, and the dimension of the first snap structure 431 gradually increases in the direction towards the second connecting portion 420. Thus, the first snap structure 431 can be easily inserted into the mounting hole 110. As the first snap structure 431 penetrates deeper, the inner wall of the mounting hole 110 will abut against the outer wall of the first snap structure 431 and squeeze the first snap structure 431, causing the first snap structure 431 to contract. The first snap structure 431 slides relative to the inner wall of the mounting hole 110 until the first snap structure 431 passes through the mounting hole 110. After the first snap structure 431 passes through the mounting hole 110, the first limiting surface 4312 of the first snap structure 431 will abut against the side of the base body 100 away from the second connecting portion 420, thereby restricting the first snap structure 431 from re-entering the mounting hole 110 and restricting the third connecting portion 430 from disengaging from the mounting hole 110.

[0047] Specifically, the third connecting portion 430 and the first snap structure 431 are integrally formed.

[0048] Refer to Figure 3 、 Figure 5 and Figure 6, according to some embodiments of the present application, it further includes a clamping member 600. A slot 432 is formed inside the third connecting portion 430, and a clamping groove 433 is formed circumferentially on the third connecting portion 430. The clamping groove 433 communicates with the slot 432. The clamping groove 433 includes a first section 4331 and a second section 4332 that are connected and communicate with each other. The width dimension of the first section 4331 is smaller than the width dimension of the second section 4332. A second clamping structure 610 is provided on the outer side of the clamping member 600. One end of the second clamping structure 610 is provided with a second guiding surface 611 and a second limiting surface 612. The second guiding surface 611 is used for sliding cooperation with the inner wall of the slot 432 to guide the clamping member 600 into the slot 432; one end of the second clamping structure 610 is clamped inside the second section 4332, and the second limiting surface 612 is used for abutting against the inner wall of the second section 4332 to limit the clamping member 600 from disengaging from the second section 4332; the middle part of the second clamping structure 610 is clamped inside the first section 4331; the other end of the second clamping structure 610 abuts against the side of the seat body 100 away from the second connecting portion 420.

[0049] It can be understood that after the first clamping structure 431 passes through the mounting hole 110 to achieve the clamping of the second connecting member 400 and the seat body 100, in order to further improve the connection stability between the second connecting member 400 and the seat body 100, a clamping member 600 is added to be clamped with the third connecting portion 430 and abut against the seat body 100. Specifically, the notch of the slot 432 forms the side of the third connecting portion 430 away from the second connecting portion 420. The clamping member 600 approaches and inserts into the slot 432 towards the slot 432. During the process of the clamping member 600 inserting into the slot 432, the second guiding surface 611 of the second clamping structure 610 will be in sliding cooperation with the inner wall of the slot 432. The second clamping structure 610 and the clamping member 600 have a certain plasticity and can be deformed under the action of an external force. The second guiding surface 611 is extruded with the inner wall of the slot 432, causing the clamping member 600 to contract until one end of the second clamping structure 610 is inserted into the second section 4332, and the second limiting surface 612 on the second clamping structure 610 will abut against the inner wall of the second section 4332, thereby restricting the clamping member 600 from disengaging from the slot 432. The middle part of the second clamping structure 610 is clamped inside the first section 4331 to limit the self-rotation of the clamping member 600. The other end of the second clamping structure 610 abuts against the side of the seat body 100 away from the second connecting portion 420 to improve the connection stability between the third connecting portion 430 and the seat body 100.

[0050] Specifically, the clamping member 600 and the second clamping structure 610 are integrally formed.

[0051] Refer to Figure 5 and Figure 6, according to some embodiments of the present application, the third connecting portion 430 is provided with a limiting structure 434, and the limiting structure 434 abuts against one side of the base body 100 close to the second connecting portion 420.

[0052] It can be understood that a limiting groove for accommodating the base body 100 is formed between the limiting structure 434 and the first clamping structure 431. The base body 100 is located in the limiting groove, and the limiting structure 434 cooperates with the first clamping structure 431 to clamp and limit the base body 100, ensuring the connection stability between the third connecting portion 430 and the base body 100, so as to prevent the third connecting portion 430 from separating from the base body 100.

[0053] Refer to Figure 5 , according to some embodiments of the present application, a sealing ring 435 is provided between the limiting structure 434 and the base body 100.

[0054] It can be understood that a sealing ring 435 is provided between the limiting structure 434 and the base body 100 to improve the waterproof effect and prevent rainwater from seeping into the base body 100 between the limiting structure 434 and the base body 100.

[0055] Refer to Figure 4 and Figure 6 , according to some embodiments of the present application, a protrusion 411 is provided on the circumference of the first connecting portion 410, a friction block 310 is provided on the side surface of the first connecting member 300, the friction block 310 is located beside the first connecting portion 410, and a groove 311 is provided on the side of the friction block 310 close to the first connecting portion 410. The protrusion 411 is in snap-fit with the groove 311.

[0056] It can be understood that there are multiple protrusions 411 and multiple grooves 311. Among them, the number of protrusions 411 is greater than or equal to the number of grooves 311. The protrusion 411 is stuck in the groove 311 to keep the current rotation angle between the first connecting member 300 and the second connecting member 400. When the first connecting member 300 rotates relative to the second connecting member 400, the protrusion 411 has a certain plasticity, and the protrusion 411 can disengage from the current groove 311, and the next protrusion 411 enters the groove 311 to ensure that the first connecting member 300 and the second connecting member 400 can rotate relative to each other, and when the first connecting member 300 stops rotating, there is a protrusion 411 in each groove 311 to define the orientation of the photovoltaic module 200.

[0057] Refer to Figure 3, According to some embodiments of the present application, the photovoltaic module 200 includes a first cover plate 210, a second cover plate 220, and a photovoltaic panel 230. The first cover plate 210 is provided with a leakage hole 211. The photovoltaic panel 230 is snap-connected to the first cover plate 210, and at least part of the photovoltaic panel 230 corresponds to the leakage hole 211. The first cover plate 210 and the second cover plate 220 are snap-connected, and a first connecting member 300 is connected to the second cover plate 220.

[0058] It can be understood that the photovoltaic panel 230 is snap-connected to the first cover plate 210 for easy disassembly and assembly of the photovoltaic panel 230, and the photovoltaic panel 230 can leak out through the leakage hole 211 to ensure that the photovoltaic panel 230 can absorb solar energy. The first cover plate 210 and the second cover plate 220 are snap-connected for easy disassembly and assembly of the first cover plate 210 and the second cover plate 220. The first connecting member 300 is connected to the second cover plate 220, and the photovoltaic panel 230 and the first cover plate 210 are driven to rotate by driving the second cover plate 220 to rotate.

The pointer of the ammeter 500 can point to the first area, the second area, or the third area.

[0060] It can be understood that by setting three areas with different back colors, it is convenient to observe the reading of the ammeter 500. For example, the first area is red, the second area is yellow, and the third area is green. When the current provided by the photovoltaic module 200 is low, the pointer of the current meter points to red. When the current provided by the photovoltaic module 200 is moderate, the pointer of the current meter points to yellow. When the current provided by the photovoltaic module 200 is high, the pointer of the current meter points to green, so as to facilitate obtaining the reading of the ammeter 500.

[0061] Refer to Figures 1 to 3 , According to some embodiments of the present application, the ammeter 500 is disposed at one end of the photovoltaic module 200 away from the first connecting member 300, and the reading window of the ammeter 500 faces away from the first connecting member 300.

[0062] It can be understood that the ammeter 500 is disposed at one end of the photovoltaic module 200 away from the first connecting member 300 to prevent the ammeter 500 from interfering with the rotation of the first connecting member 300, and the reading window of the ammeter 500 faces away from the first connecting member 300 for easy observation of the reading of the ammeter 500.
