[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] Please refer to Figures 1 to 5 , the solar charging device in the embodiment of this utility model includes a carrier base 10 and a photovoltaic panel 20. A carrier groove 110 is formed concave in the top of the carrier base 10. A first carrier plate 30 and a second carrier plate 40 are sequentially arranged from top to bottom in the carrier groove 110. The first carrier plate 30 and the second carrier plate 40 are coaxially rotatably connected in the carrier groove 110. Understandably, the first carrier plate 30 and the second carrier plate 40 are located on the same axis.

[0028] Inner concave first and second rotating grooves are sequentially formed in the inner side wall of the carrier groove 110 from top to bottom. The first carrier plate 30 is slidably connected in the first rotating groove, and the second carrier plate 40 is slidably connected in the second rotating groove. That is, the outer edge of the first carrier plate 30 is embedded in the first rotating groove, and the outer edge of the second carrier plate 40 is embedded in the second rotating groove. The first and second rotating grooves are also used to limit the heights of the first and second carrier plates 30 and 40, so as to prevent the distance between the first and second carrier plates 30 and 40 from changing and improve the stability of the overall structure.

[0029] A rotating motor 120 is arranged at the bottom of the carrier groove 110. The rotating motor 120 is electrically connected to a rotating shaft 130. One end of the rotating shaft 130 facing away from the rotating motor 120 penetrates through the second carrier plate 40 and is fixedly connected to the first carrier plate 30. The second carrier plate 40 is fixedly connected to the rotating shaft 130. Understandably, the rotating shaft 130, the first carrier plate 30 and the second carrier plate 40 are located on the same axis. The rotating motor 120 is used to drive the rotating shaft 130 to rotate axially, and then drive the first carrier plate 30 and the second carrier plate 40 to rotate coaxially.

[0030] A photovoltaic panel 20 is disposed on a side of the first carrier plate 30 facing away from the second carrier plate 40. The photovoltaic panel 20 is used to receive solar energy and convert it into electrical energy. Understandably, a storage battery electrically connected to the photovoltaic panel 20 is further disposed in the carrier groove 110, and the storage battery is used to store the converted electrical energy. After the position of the sun changes, by rotating the first carrier plate 30 in the carrier groove 110, the orientation of the photovoltaic panel 20 can be adjusted, so that it always corresponds to the position of the sun, which can improve the continuous solar energy receiving ability of the photovoltaic panel 20 to a certain extent, and further improve the continuous charging ability of the storage battery, and improve the endurance of the solar charging device to a certain extent.

[0031] In this embodiment, a lifting mechanism 50 is disposed on a side of the second carrier plate 40 facing the first carrier plate 30. The lifting mechanism 50 passes through the first carrier plate 30 and is rotatably connected to one end of the photovoltaic panel 20, and the other end of the photovoltaic panel 20 is rotatably connected to the first carrier plate 30. By providing the lifting mechanism 50, the tilt angle of the photovoltaic panel 20 can be adjusted, so that the alignment of the photovoltaic panel 20 with the sun is more accurate, ensuring that solar energy can be fully received and improving the electrical energy storage efficiency of the storage battery. Understandably, through the coaxial rotation setting between the first carrier plate 30 and the second carrier plate 40, the relative position between the lifting mechanism 50 and the photovoltaic panel 20 can be ensured to remain unchanged, avoiding the lifting mechanism 50 from hindering the rotation of the first carrier plate 30, that is, avoiding the lifting mechanism 50 from hindering the position adjustment of the photovoltaic panel 20 in the horizontal direction.

[0032] Specifically, the lifting mechanism 50 includes a lifting motor 510 and a lifting rod 520. The lifting motor 510 is disposed on a surface of the second bearing plate 40 facing the first bearing plate 30. The lifting motor 510 is electrically connected to the lifting rod 520. A first baffle 210 and a second baffle are disposed on a surface of the photovoltaic panel 20 facing the first bearing plate 30. A rotating rod 220 is connected between the first baffle 210 and the second baffle. The rotating rod 220 penetrates through an end of the lifting rod 520 facing away from the lifting motor 510, and the rotating rod 220 is rotatably connected to the lifting rod 520. The lifting motor 510 is configured to drive the lifting rod 520 to lift vertically. When the lifting rod 520 ascends vertically, one end of the photovoltaic panel 20 rises accordingly, and the other end of the photovoltaic panel 20 rotates relative to the first bearing plate 30, so that the degree of the angle between the photovoltaic panel 20 and the first bearing plate 30 increases. Conversely, the degree of the angle between the photovoltaic panel 20 and the first bearing plate 30 decreases. Preferably, an avoidance groove 310 penetrating through the first bearing plate 30 is formed on the first bearing plate 30, and the positions of the avoidance groove 310 correspond to those of the first baffle 210 and the second baffle. It can be understood that the positions of the lifting rod 520 and the rotating rod 220 also correspond to those of the avoidance groove 310. By providing the avoidance groove 310, it is possible to prevent the first bearing plate 30 from hindering the adjustment of the tilt angle of the photovoltaic panel 20 by the lifting mechanism 50.

[0033] Extension rods 240 are connected to opposite side walls of the photovoltaic panel 20. The two extension rods 240 are located at an end of the photovoltaic panel 20 facing away from the lifting mechanism 50. Two support blocks 320 are disposed on a surface of the first bearing plate 30 facing away from the second bearing plate 40. The positions of the two support blocks 320 correspond to those of the two extension rods 240 respectively. An end of the extension rod 240 facing away from the photovoltaic panel 20 is rotatably connected to the support block 320. When the lifting mechanism 50 drives an end of the photovoltaic panel 20 facing away from the extension rod 240 to lift vertically, the extension rod 240 rotates axially, avoiding bending or damage to the photovoltaic panel 20 caused by fixed connection.

[0034] When one end of the photovoltaic panel 20 ascends vertically, the projected length of the photovoltaic panel 20 on the first bearing plate 30 becomes smaller, that is, the distance between the lifting mechanism 50 and the support block 320 becomes smaller. Therefore, the two support blocks 320 are both slidably connected to the first bearing plate 30. Specifically, two sliding grooves 330 are concavely formed on a surface of the first bearing plate 30 facing away from the second bearing plate 40. The two support blocks 320 are respectively slidably connected in the two sliding grooves 330. The sliding grooves 330 extend from the support blocks 320 towards the lifting mechanism 50, and the sliding grooves 330 are parallel to the photovoltaic panel 20.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example.
