In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0036] like Figure 1 and Figure 2 As shown, this embodiment provides a solar panel device, including a solar panel 10 and a support assembly 20, wherein the support assembly 20 is used to support the solar panel 10 so that the solar panel 10 absorbs sunlight at a better angle and converts solar energy over a maximum area. In practical applications, according to the size of the solar panel 10, one, two or more support assemblies 20 can be selectively provided on the back of each solar panel 10 to ensure the stability of the support.

[0037] like Figure 1 and Figure 2As shown, the support assembly 20 includes a support member 21 and a tie 22, both of which are located on the back of the solar panel 10. The support member 21 is a plate-like structure, and the top end of the support member 21 is rotatably connected to the top end of the solar panel 10, and the bottom end of the support member 21 can be placed on the ground as a support end. The tie 22 has at least two free ends, one of which is fixedly connected to the support member 21, and the other free ends are fixedly connected to the back of the solar panel 10. The end of the tie 22 fixedly connected to the solar panel 10 is defined as the first end of the tie 22, and the end of the tie 22 fixedly connected to the support member 21 is defined as the second end of the tie 22, that is, the first end of the tie 22 is connected to the back of the solar panel 10, and the first end of the tie 22 is adjustable in position to the support member 21 in the length direction of the support member 21 to change the maximum opening and closing angle of the support member 21 relative to the solar panel 10.

[0038] The solar panel device provided in this embodiment can change the maximum opening and closing angle of the support member 21 relative to the solar panel 10 by adjusting the connection position of the second end of the pull strap 22 on the support member 21 along the length direction of the support member 21, so that the solar panel 10 has different inclination angles. The user can adjust the inclination angle of the solar panel 10 in real time according to different lighting conditions, receive sunlight at a better angle, obtain the best power generation effect, improve power generation efficiency, and enhance the adaptability and flexibility of the solar panel device.

[0039] In an optional embodiment, the support member 21 is made of a lightweight material, such as aluminum alloy, high-strength nylon, etc., so that the support member 21 has good stability and load-bearing capacity.

[0040] In an optional embodiment, in order to achieve the adjustable position of the second end of the drawstring 22 on the support member 21, as Figure 1 and Figure 2 As shown, the second end of the pull strap 22 is fixedly connected with a locking member 30, and the support member 21 is provided with a plurality of mounting holes 211, and the plurality of mounting holes 211 are arranged at intervals at least along the length direction of the support member 21, and the locking member 30 can be fixed on the mounting hole 211, and the second end of the pull strap 22 can be fixedly connected to any one of the mounting holes 211 through the locking member 30. By installing the locking member 30 in different mounting holes 211 in the length direction of the support member 21, the connection position of the second end of the pull strap 22 on the support member 21 can be adjusted, so that the maximum opening and closing angle of the support member 21 relative to the solar panel 10 can be changed, so that the solar panel 10 has different tilt angles. For example, as Figure 3 As shown, when the second end of the pull strap 22 is fixed in the mounting hole 211 in the middle area of ​​the support member 21 by the locking member 30, the maximum opening and closing angle α of the support member 21 relative to the solar panel 10 is small; Figure 4As shown, when the second end of the pull strap 22 is fixed in the mounting hole 211 in the bottom area of ​​the support member 21 through the locking member 30, the maximum opening and closing angle α of the support member 21 relative to the solar panel 10 is relatively large. Therefore, the closer the locking member 30 is installed to the bottom, the larger the maximum opening and closing angle α of the support member 21 relative to the solar panel 10 is generally.

[0041] In an optional embodiment, if Figure 2 As shown, a plurality of mounting holes 211 are arranged in a square array and cover the entire support member 21. This arrangement can not only provide more different mounting positions for the locking member 30, but also make the support member 21 lighter, and can also effectively reduce the shadow area of ​​sunlight blocked on the back of the solar panel 10, thereby increasing the power generation on the back of the solar panel 10.

[0042] In an optional embodiment, if Figure 5 and Figure 6 As shown, the locking member 30 includes a first lock buckle 31 and a second lock buckle 32. The second lock buckle 32 is fixedly connected to the second end of the drawstring 22. A lock hole 321 is provided in the second lock buckle 32. When installed, the second lock buckle 32 is located on the lower surface of the support member 21. One end of the first lock buckle 31 passes through the mounting hole 211 from the upper surface of the support member 21 and is engaged in the lock hole 321 of the second lock buckle 32, thereby achieving a stable engagement between the first lock buckle 31 and the second lock buckle 32, and also fixing the second lock buckle 32 to the support member 21. The above-mentioned locking member 30 can achieve a reliable connection between the drawstring 22 and the support member 21, and the mounting and disassembly of the clamping method is convenient and quick, and the mounting hole 211 of the locking member 30 can be quickly replaced according to needs. In another optional embodiment, the first lock buckle 31 is fixedly connected to the second end of the drawstring 22, and the second lock buckle 32 is located on the upper surface of the support member 21, which can also achieve the above-mentioned effect, which will not be repeated here.

[0043] In an optional embodiment, if Figure 5 and Figure 6As shown, the first lock buckle 31 includes a limiting portion 311 and a clamping portion 312 connected to each other. The radial size of the limiting portion 311 and the radial size of the second lock buckle 32 are both larger than the aperture of the mounting hole 211. The limiting portion 311 and the second lock buckle 32 are respectively arranged on both sides of the support member 21, and the clamping portion 312 can pass through the mounting hole 211 and be clamped in the locking hole 321 of the second lock buckle 32. During installation, the second lock buckle 32 abuts against the lower surface of the support member 21, and the clamping portion 312 of the first lock buckle 31 passes through the installation hole 211 from the upper surface of the support member 21 and is clamped in the locking hole 321 of the second lock buckle 32, while the limiting portion 311 of the first lock buckle 31 abuts against the upper surface of the support member 21. Therefore, the second lock buckle 32 and the limiting portion 311 respectively abut against the upper and lower surfaces of the support member 21 to achieve a limiting effect, and the limiting portion 311 cooperates with the locking hole 321 to achieve a clamping and fixing effect, thereby achieving a stable and reliable clamping connection between the first lock buckle 31 and the second lock buckle 32, and stably fixing the second lock buckle 32 to the support member 21.

[0044] In an optional embodiment, if Figure 6 As shown, the locking hole 321 is provided with a limiting protrusion 322 on the periphery, and the clamping part 312 is provided with a limiting groove 313 on the periphery, and the limiting protrusion 322 is clamped in the limiting groove 313. When the clamping part 312 is inserted into the locking hole 321, the clamping part 312 can be stably clamped in the locking hole 321 through the limiting cooperation of the limiting protrusion 322 and the limiting groove 313. Among them, the first lock buckle 31 and the second lock buckle 32 can be made of slightly deformable materials such as plastic, which is convenient for clamping cooperation. In another optional embodiment, the locking hole 321 is provided with a limiting groove 313 on the periphery, and the clamping part 312 is provided with a limiting protrusion 322 on the periphery, which can also achieve the above-mentioned clamping effect, which will not be repeated here.

[0045] In another optional embodiment, the locking member 30 can also be a combination of a bolt and a nut, that is, the second end of the pull strap 22 is fixedly connected with a bolt. During installation, one end of the bolt is passed through the mounting hole 211 from the lower side of the support member 21, and then the nut is screwed on the bolt on the upper side of the support member 21. The second end of the pull strap 22 can also be fixedly connected to any mounting hole 211 on the support member 21.

[0046] In an optional embodiment, if Figure 1As shown, the drawstring 22 includes a first connection belt 221, a second connection belt 222, and a third connection belt 223, one end of which intersects at the same point. The free ends of the second connection belt 222 and the third connection belt 223 are the first ends of the above-mentioned drawstring 22. The free ends of the second connection belt 222 and the third connection belt 223 are both connected to the back of the solar panel 10 and are staggered in the height direction. The free end of the first connection belt 221 is the second end of the above-mentioned drawstring 22. The free end of the first connection belt 221 is adjustable in position to the support member 21 in the length direction of the support member 21 through the locking member 30. Specifically, the free end of the second connection belt 222 is fixedly connected to the top end of the solar panel 10, and the free end of the third connection belt 223 is fixedly connected to the bottom end of the solar panel 10. Among them, at least one of the first connection belt 221, the second connection belt 222, and the third connection belt 223 can be an elastic belt, and the others can be cloth belts without elasticity.

[0047] The user can pull the support member 21 to rotate around the top of the solar panel 10, so that the support member 21 can be unfolded or folded in one step, which is convenient and quick to operate. When unfolded, the support member 21 is set at an angle with the solar panel 10 so that the solar panel 10 can fully absorb sunlight and convert solar energy over the maximum area. At this time, the first connecting belt 221, the second connecting belt 222 and the third connecting belt 223 are in a tight state and are radially distributed in a triangular shape, thereby forming a triangular stable support structure and improving the support stability of the support member 21. When closed, the support member 21 is folded in the direction close to the solar panel 10 to fit the solar panel 10 as closely as possible. At this time, the first connecting belt 221, the second connecting belt 222 and the third connecting belt 223 are in a relaxed state, occupying little space and convenient for storage.

[0048] In an optional embodiment, if Figure 7 As shown, the top of the support member 21 is provided with a receiving groove 212 and hinged parts 213 located on both sides of the receiving groove 212, and the top back of the solar panel 10 is fixedly connected with a connecting member 12, which is accommodated in the receiving groove 212. The connecting member 12 is provided with a through-shaft hole, and each hinged part 213 is provided with a rotation hole at a position corresponding to the shaft hole, and the shaft passes through the shaft hole and the rotation hole, and the hinged part 213 is rotatably connected with the connecting member 12 through the shaft. Through the above arrangement, the support member 21 can rotate smoothly around the shaft, with a simple structure and convenient operation.

[0049] In an optional embodiment, if Figure 2 As shown, the solar panel 10 includes at least two battery panels 11, and two adjacent battery panels 11 are foldable along a folding line 13. Figure 2As shown, taking four solar panels 11 as an example, there is a folding line 13 between each two adjacent solar panels 11. When the solar panel 10 is in the unfolded state, the four solar panels 11 are located in the same plane, and the two support assemblies 20 support the solar panel 10 so that the solar panel 10 has a larger illuminated area after unfolding, thereby increasing the output power of the solar panel 10. In the stored state, the support assembly 20 is first stored, and then the two outermost solar panels 10 are folded in half along their folding lines 13 onto the two middle solar panels 11, and then the two middle solar panels 11 are folded in half along the middle folding line 13. The volume is small and easy to carry and store. Therefore, the solar panel 10 can be quickly unfolded and stored through simple operations without complicated installation and disassembly processes, which improves the user experience and convenience.

[0050] like Figure 2 As shown, a long hole 14 is provided between two adjacent solar panels 11, and the long hole 14 is located on the folding line 13 and extends along the folding line 13. Two long holes 14 can be provided on each folding line 13, and the two long holes 14 are arranged at intervals along the direction of the folding line 13. By providing the long holes 14, the solar panel 11 can be made easier to fold, and the problem of rebound after the solar panel 10 is folded can be improved.
