[0032] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0033] Embodiment 1:

[0034] like Figure 1-3 As shown, a telescopic solar portable power source includes two shells 1.

[0035] A solar cell group 2 is arranged inside the two shells 1, and the solar cell group 2 includes a plurality of solar cell panels 4 and a connecting frame 5. A receiving groove is opened on the inner wall of one side of the shell 1, and a support assembly 7 is arranged in the receiving groove. The support assembly 7 includes a support plate 1 9 and a support plate 2 10. The support plate 1 9 is rotatably connected to one end of the support plate 2 10 through a rotating shaft 1 8, and the other end of the support plate 2 10 is rotatably connected to the inner wall of the receiving groove through a rotating shaft 2 11, and the rotating shaft 1 8 and the rotating shaft 2 11 are both damping rotating shafts.

[0036] After unfolding the solar cell group 2, rotate the support plate 2 10 to a certain angle, and then rotate the support plate 1 9 to be parallel to the ground or other places, so that the support plate 1 9 can reliably contact the ground. At this time, the housing 1 is already in a tilted state. After the adjustment is completed, just let go.

[0037] The device is provided with a support plate 1 9 and a support plate 2 10. The support plate 2 10 can be rotated to adjust the inclination angle of the housing 1, so that the solar panel 4 can better receive sunlight. After the angle is adjusted, the support plate 1 9 is rotated again so that the support plate 1 9 can reliably contact the ground, thereby providing stable support for the device and preventing the device from tipping over and causing damage.

[0038] like Figure 2-4As shown, the solar panel 4 is fixedly mounted on the inner wall of the connecting frame 5, a slide groove 6 is provided on the top of the connecting frame 5, and a slider 12 is fixedly connected to the bottom of the connecting frame 5, and two adjacent connecting frames 5 are slidably matched through the slide groove 6 and the slider 12.

[0039] The two connection frames 5 located on the sides are fixedly connected to the inner walls of the two shells 1 respectively.

[0040] One of the connection frames 5 has a built-in battery 19 , the discharge terminal of the battery 19 is electrically connected to a power output interface, the power output interface is arranged on the side wall of the connection frame 5 , and the output ends of all solar panels 4 are electrically connected to the charging terminal of the battery 19 .

[0041] The outer shell 1 is pulled to one side, and the outer shell 1 is used to drive the connecting frame 5 connected thereto to extend outward, and the connecting frame 5 is used to drive the remaining connecting frames 5 to extend outward in sequence until all the solar panels 4 are exposed to the outside, and the solar panels 4 are used to absorb sunlight and convert solar energy into electrical energy and store it in the battery 19. When the user needs electricity, the power connector of the external device is inserted into the power output interface to supply power.

[0042] Embodiment 2:

[0043] A retractable solar portable power source, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1 , Figure 6 and Figure 7 As shown:

[0044] A protection component is arranged on one side of the two shells 1, and the protection component includes a protection curtain 13 and a rotating shaft 3 17. The protection curtain 13 is rotatably connected to the inner wall of one of the shells 1 through the rotating shaft 3 17, and a handle 3 is fixedly connected to the side wall of the shell 1.

[0045] The other end of the protective curtain 13 penetrates the housing 1 and is connected to the side wall of another housing 1 through a connecting piece, and the outer wall of the housing 1 is fixedly connected to a fixing rod 2 16 , and the end of the protective curtain 13 away from the rotating shaft 3 17 is fixed with a limiting rod.

[0046] The connecting member includes a fixing rod 14 and an elastic connecting ring 15. The fixing rod 14 is fixedly connected to the outer wall of the protective curtain 13. One end of the elastic connecting ring 15 is fixedly connected to the outer wall of the fixing rod 14, and the other end of the elastic connecting ring 15 is movably sleeved on the outer wall of the fixing rod 2 16.

[0047] The outer wall of the rotating shaft 3 17 is fixedly connected with a torsion spring 18 , and the other end of the torsion spring 18 is fixed to the inner wall of the housing 1 .

[0048] When the device needs to be unfolded to absorb sunlight, the elastic connecting ring 15 is first removed from the fixing rod 2 16, and then the external force applied to the protective curtain 13 is stopped. At this time, the torsion spring 18 drives the rotating shaft 3 17 to rotate, so that the protective curtain 13 is rolled up, but due to the setting of the limit rod, the protective curtain 13 will not be completely retracted into the shell 1, and the fixing rod 1 14 and the elastic connecting ring 15 are still located outside the shell 1, and then the shell 1 can be pulled to drive the solar cell panel 4 and the connecting frame 5 to extend outward; when the device is not needed, the shell 1 is pushed inward to drive all the connecting frames 5 to retract and overlap inward, and finally the fixing rod 14 is used to pull the protective curtain 13 to extend outward, and the elastic connecting ring 15 is sleeved on the outer wall of the fixing rod 2 16, and the device can be carried using the handle 3.

[0049] The device can protect the solar panel 4 by providing the protective curtain 13, so as to prevent the surface of the solar panel 4 from being scratched or damaged by external factors when not in use, and even affect its internal structure and performance, thereby increasing the service life of the device.

[0050] Working principle: When the device is in use, first remove one end of the elastic connection ring 15 from the fixing rod 2 16, and then loosen the elastic connection ring 15, so that the torsion spring 18 uses its own characteristics to drive the rotation shaft 3 17 to rotate and the protective curtain 13 to roll up. Since the protective curtain 13 is blocked by the limit rod, it will not be completely retracted into the shell 1. The fixing rod 1 14 and the elastic connection ring 15 can be located outside the shell 1, which is convenient for use. At this time, there is no restriction between the two shells 1 and they can be pulled to both sides. Pulling the shell 1 can drive multiple connection frames 5 to extend outward in sequence until all solar panels 4 are exposed to the outside. Then rotate the support plate 2 10 so that the device can be tilted at a certain angle, so that it can better absorb sunlight. Then, it is necessary to rotate the support plate 1 9 to be parallel and fit with the ground, which can provide stable support for the device. At this point, the whole process of the device is completed. Then, the solar panel 4 can be used to convert the absorbed solar energy into electrical energy and store it in the battery 19. The user can insert the power plug of the external device that needs to be charged into the power output interface to achieve power supply.

[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
