[0035] Example 1

[0036] This embodiment provides a photovoltaic power generation device that generates electricity using solar energy. Figure 1 This is a schematic diagram of the three-dimensional structure of the photovoltaic power generation device provided by the embodiment of the utility model. Figure 3 This is a schematic diagram of the three-dimensional structure of the photovoltaic power generation device provided by the embodiment of the utility model in the storage state. Figure 1 and Figure 3 The photovoltaic power generation device includes a bracket and a photovoltaic panel 10. Figure 1 The photovoltaic panel 10 is in a supporting state. Figure 3 The photovoltaic panel 10 is in a free state.

[0037] The bracket is used to support and position the photovoltaic panel 10 to constrain the orientation and tilt angle of the photovoltaic panel 10 so as to fully utilize solar energy for power generation. The bracket includes a positioning frame 20 and a telescopic rod 30. The positioning frame 20 is suitable for being fixed on a fixed surface to position the photovoltaic power generation device. The telescopic rod 30 has two opposite ends. One end of the telescopic rod 30 is pivotally connected to the positioning frame 20, and the other end of the telescopic rod 30 is used to be pivotally connected to the photovoltaic panel 10.

[0038] The photovoltaic panel 10 is used to receive sunlight to convert solar energy into electrical energy. The photovoltaic panel 10 includes a positioning portion 12 and a support portion 13. The positioning portion 12 is used to be pivotally connected to the positioning frame 20, and the support portion 13 is used to be pivotally connected to the telescopic rod 30. The positioning portion 12 and the support portion 13 are arranged on opposite sides of the photovoltaic panel 10, and the support portion 13 is pivotally connected to the other end of the telescopic rod 30.

[0039] Specifically, the photovoltaic panel 10 includes a frame 11 and a photovoltaic panel 14. The photovoltaic panel 14 is a functional component for solar power generation, which is used to receive sunlight to convert solar energy into electrical energy. The frame 11 is used to fix the photovoltaic panel 14, and the frame 11 surrounds the outer periphery of the photovoltaic panel 14. The positioning portion 12 and the support portion 13 are both arranged on the frame 11. In this embodiment, the positioning portion 12 and the support portion 13 are arranged on two opposite sides of the frame 11.

[0040] In this embodiment, the support portion 13 and the telescopic rod 30 are detachably arranged, and the photovoltaic panel 10 includes a supporting state in which the (support portion 13) is connected to the telescopic rod 30 and a free state in which the (support portion 13) and the telescopic rod 30 are detached. Figure 1 As shown in FIG. 1 , the length of the telescopic rod 30 can be adjusted to different sizes to position the photovoltaic panel 10 and the positioning frame 20 at different inclination angles. Figure 3 and Figure 5 As shown), the telescopic rod 30 can be pivoted to within the outer contour of the positioning frame 20, and the photovoltaic panel 10 can be pivoted to a side close to the positioning frame 20.

[0041] See also Figure 3 and Figure 5 As shown, this positioning state is the storage state of the photovoltaic power generation device, the telescopic rod 30 is pivoted to the outer contour of the positioning frame 20, and the photovoltaic panel 10 is pivoted to the side close to the positioning frame 20. The volume of the photovoltaic power generation device is minimized, the packaging volume is minimized, and the transportation cost is lowest.

[0042] It should be noted that "within the outer contour of the positioning frame" is understood to be within the range of the length, width and thickness of the positioning frame. When the telescopic rod is pivoted to the outer contour of the positioning frame, the telescopic rod basically does not occupy additional packaging space volume.

[0043] The above-mentioned "free state" is understood to be a state in which the photovoltaic panel can rotate freely without being restricted by the telescopic rod. In the free state, the photovoltaic panel can pivot to abut against one side of the positioning frame, so that the overall volume of the photovoltaic panel and the positioning frame is minimized.

[0044] The photovoltaic power generation device provided by the utility model can determine the direction of the photovoltaic panel after the bracket is fixed. In the supported state, the angle of the photovoltaic panel can be freely adjusted by the telescopic rod, and the photovoltaic power generation device is easy to install. In the free state, the telescopic rod can be pivoted to the range of the outer contour of the positioning frame without occupying additional storage space. The photovoltaic panel can be pivoted to the side close to the positioning frame, so that the photovoltaic power generation device is compact and easy to pack and transport.

[0045] In a specific embodiment, please combine Figure 1 and Figure 2 As shown, the bracket also includes a clamping portion 40 for positioning the telescopic rod 30, so as to position the telescopic rod 30 within the outer contour of the positioning frame 20 (the storage state of the telescopic rod). Specifically, the clamping portion 40 is fixedly arranged on the positioning frame 20, and includes a clamping wall 41, a clamping cavity 42 and a clamping arm 44. The clamping cavity 42 is surrounded by the clamping wall 41, and is used to accommodate the pivot connection end of the telescopic rod 30. In other words, one end of the telescopic rod 30 is at least partially located in the clamping cavity 42 and can pivot relative to the clamping cavity 42. The clamping arm 44 is arranged at the open end of the clamping wall 41, and the clamping arms 44 are arranged in pairs, and the distance between the relative clamping arms 44 is less than the width of the clamping cavity 42. The clamping arms 44 are used to guide the telescopic rod 30 into the clamping cavity 42 and limit the telescopic rod 30 in the clamping cavity 42 to a certain extent. The telescopic rod 30 includes a storage state, such as Figure 3 In the state shown, in the storage state, the telescopic rod 30 is located within the outer contour of the positioning frame 20, and one end of the telescopic rod 30 is held in place by the clamping arm 44, and will not fall out of the clamping cavity 42. When the telescopic rod 30 needs to be pivoted out of the clamping cavity 42, only an external force to overcome the clamping arm 44 is required.

[0046] In order to make the shape of the photovoltaic power generation device in the storage state stable, it is convenient for stacking and batch transportation. In the specific embodiment, please refer to Figure 5 and Figure 6 As shown, the support portion 13 includes a limit platform 131, which is used to cooperate with the surface of the positioning frame 20. When the photovoltaic panel 10 pivots to the side close to the positioning frame 20, the limit platform 131 and the outer surface of the positioning frame 20 are in contact with each other to limit the photovoltaic panel 10 from further rotating relative to the positioning frame 20. In this way, in the process of storing the photovoltaic power generation device, the limit platform 131 can be used to determine that the pivoting is in place. In addition, the mutual support between the photovoltaic panel 10 and the bracket can withstand greater pressure, which is convenient for stacking photovoltaic power generation devices and batch transportation, improving transportation efficiency, and reducing the damage rate during transportation.

[0047] In a specific embodiment, the positioning frame 20 includes a main frame 21, and when the photovoltaic panel 10 is pivoted to the side close to the main frame 21, the photovoltaic panel 10 is perpendicular to the thickness direction of the main frame 21. The main frame 21 as a whole extends roughly in a plane, which is hereinafter referred to as the extension plane. The direction perpendicular to the extension plane is defined as the thickness direction of the main frame 21. Parallel to the extension plane, the main frame 21 has a width direction and a length direction, and the thickness dimension of the main frame 21 is smaller than the width and length dimensions of the main frame 21. That is to say, in the storage state, the main frame 21 and the photovoltaic panel 10 are stacked along the thickness direction, so that the volume of the photovoltaic power generation device is smaller.

[0048] Specifically, when the photovoltaic panel 10 is pivoted to the side close to the positioning frame 20, the extension plane where the main frame body 21 is located is parallel to the photovoltaic panel 10. In this embodiment, the main frame body 21 is frame-shaped and is formed by connecting tubular members. The center line of the tubular member is basically located in the above-mentioned extension plane or parallel to the extension plane. Preferably, the tubular member is a square tube, that is, a slender tube with a square cross section.

[0049] In one embodiment, see Figure 1 and 3 The positioning frame 20 further includes a hanger 23 suitable for hanging on the rod-shaped member to position the main frame body 21, and the hanger 23 is fixedly arranged at one end of the main frame body 21 close to the positioning portion 12. Generally, the rod-shaped member is a horizontal straight rod, and the hanger 23 is a hook, and the number is at least two. After the two hooks are hung on the rod-shaped member, the main frame body 21 will not fall under the action of gravity.

[0050] In another embodiment, see Fig. 9 As shown, the positioning frame 20 does not include a hanging frame, or the hanging frame is removed from the positioning frame 20, and the main frame body 21 is used alone. Fig. 9 In the illustrated embodiment, the photovoltaic power generation device is connected to the fixed surface via the main frame 21 to position the photovoltaic panel 10, and no mounting bracket is provided.

[0051] For specific embodiments, see Figure 3 and Figure 4 and Figure 7The telescopic rod 30 includes a first rod 32 and a second rod 34. The first rod 32 is nested inside the second rod 34 and can reciprocate along the axial direction of the second rod 34. A positioning hole 340 is provided on the rod wall of the second rod 34. The telescopic rod 30 also includes a positioning member 36 provided on the side wall of the first rod 32. The positioning member 36 is used to cooperate with the positioning hole 340 to locate the position of the first rod 32 relative to the second rod 34. In this embodiment, the first rod 32 and the second rod 34 are both straight rods, preferably square rods with a square cross section. The cross-sectional shape of the first rod 32 is slightly smaller than the inner hole shape of the second rod 34, so that the first rod 32 can reciprocate in the second rod 34, thereby adjusting the overall length of the telescopic rod 30. The cooperation of the positioning hole 340 and the positioning member 36 can position the telescopic rod 30 at different length sizes. When the positioning member 36 cooperates with the positioning hole 340, it corresponds to a specific length of the telescopic rod 30. In this way, the length of the telescopic rod 30 can be determined by the positioning hole 340 cooperated with the positioning member 36, and then the inclination angle of the photovoltaic panel 10 can be determined.

[0052] For details, please combine Figure 7 and Figure 8 The positioning member 36 includes a positioning sleeve 361, a return spring 363 disposed in the positioning sleeve 361, and a positioning bead 362. The positioning sleeve 361 is fixedly disposed on the side wall of the first rod 32, the outer end of the positioning sleeve 361 is open, one end of the return spring 363 abuts against the positioning bead 362, and the other end abuts against the inner wall of the positioning sleeve 361. The positioning bead 362 has a tendency to move out of the opening under the action of the return spring 363. Under the action of the return spring 363, a portion of the positioning bead 362 protrudes from the opening of the positioning sleeve 361, so as to be embedded in the positioning hole 340 and to be limitedly matched with the positioning hole 340.

[0053] Furthermore, the positioning sleeve 361 partially protrudes from the outer surface of the side wall of the first rod 32, and the end of the second rod 34 away from the positioning frame 20 is provided with a stopper 341 for cooperating with the positioning sleeve 361 to limit the position, and the stopper 341 is used to limit the first rod 32 from escaping from the second rod 34. Specifically, the stopper 341 is arranged in pairs, and the stopper 341 reduces the size of the inner hole at the end of the second rod 34, and the positioning sleeve 361 cannot pass through the stopper 341. The stopper 341 cooperates with the positioning sleeve 361 to limit the first rod 32 from escaping from the second rod 34. In this embodiment, the stopper 341 is a rib plate formed at the end of the side wall of the second rod 34, and the rib plates on both sides extend toward each other.

[0054] In a specific embodiment, when the positioning bead 362 is limitedly matched with the positioning hole 340, the return spring 363 is in a compressed state. The return spring 363 in the compressed state pushes the positioning bead 362, so that the positioning bead 362 is abutted against the side wall of the positioning hole 340. The side wall of the positioning hole 340 has a reverse pressing force on the positioning bead 362, and the spring 363 is kept in a compressed state. The advantage of such a setting is that it can improve the positioning accuracy of the positioning bead and the positioning hole, maintain the coaxiality of the first rod and the second rod, prevent the first rod from shaking in the second rod, and eliminate collision noise.

[0055] In a specific embodiment, the positioning members 36 include at least two pairs, each pair of positioning members 36 is relatively disposed on the side wall of the first rod 32, and the positioning members 36 are spaced apart in the circumferential direction of the first rod 32. Figure 7 and Figure 8 The adjacent positioning members 36 have a phase difference of 90 degrees, and the two pairs of positioning members 36 are distributed at intervals along the circumference of the first rod 32 to position the first rod 32 from two directions, thereby ensuring the positioning stability of the first rod 32 and reducing the risk of shaking.

[0056] In order to ensure the reliability of positioning the first rod and the second rod, in a specific embodiment, see Figure 4 The telescopic rod 30 further includes a locking member 35 for locking the first rod 32 and the second rod 34 to restrict their relative movement. Specifically, the locking member 35 is threadedly connected to the side wall of the second rod 34. The locking member 35 includes an operating portion and a pressing portion. Rotating the operating portion in a first direction can increase the contact pressure between the pressing portion and the side wall of the first rod 32, thereby fixing the first rod 32 and the second rod 34. When the length of the telescopic rod needs to be adjusted, the operating portion only needs to be rotated in the opposite direction, so that the pressing portion can gradually loosen the interaction with the first rod 32 until it is completely disengaged from the first rod 32, and the first rod 32 can slide relative to the second rod 34.

[0057] For specific embodiments, see Figure 7 and Figure 8 A spring pin 323 is provided at the end of the first rod 32, and the first rod 32 is pivotally and detachably connected to the support portion 13 through the spring pin 323. Specifically, the support portion 13 has opposite pin holes (not shown), and the spring pin 323 is suitable for being inserted into the pin holes and can be withdrawn from the pin holes under the action of external force to separate the first rod 32 and the support portion 13. The first rod 32 pivots relative to the support portion 13 around the axis of the pin hole.

[0058] Obviously, the above described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
