In another embodiment, the battery cover 26 may also be detachably mounted on the carrying body 21 by clamping, magnetic connection, or the like, so that the battery cover 26 can be mounted and dismounted in advance when the battery a needs to be dismounted.

In one embodiment, the first photovoltaic panel 11 is substantially rectangular in configuration, having four sides disposed opposite to each other in pairs, and for convenience of description, two sides disposed opposite to each other in a first direction are defined as a first side, and two sides disposed opposite to each other in a second direction perpendicular to the first direction are defined as a second side; if the light-sensing surface and the backlight surface of the first photovoltaic panel 11 are opposite to each other in the vertical direction of the entire device, the first direction may be a front-back direction of the entire device, and the second direction may be a left-right direction of the entire device.

Correspondingly, the number of the second photovoltaic panels 12 is two, and the second photovoltaic panels are respectively located on the second side of the first photovoltaic panel 11; in one embodiment, one of the second photovoltaic panels 12 can be mounted on the power storage device 20 (specifically, the carrier body 21) via a single-degree-of-freedom rotating shaft (i.e., only one rotating shaft extending along the first direction), and the other second photovoltaic panel 12 can be mounted on the power storage device 20 (specifically, the carrier body 21) via a two-degree-of-freedom rotating shaft (i.e., two rotating shafts extending along the first direction and spaced apart from each other along the second direction). On the one hand, two second photovoltaic panels 12 and the first photovoltaic panel 11 are folded and stored in a three-fold manner, that is: referring to fig. 6 and 7, the second photovoltaic panel 12 with single degree of freedom may be turned over toward the first photovoltaic panel 11, so that the light-sensing surface thereof is stacked on the light-sensing surface of the first photovoltaic panel 11 in the up-down direction; then, referring to fig. 8 and 9, by turning over another second photovoltaic panel 12 with two degrees of freedom, the photosensitive surface of the second photovoltaic panel 12 is stacked on the backlight surface of the previous second photovoltaic panel 11 along the up-down direction by using the difference of the rotation axes of the two second photovoltaic panels 12, thereby completing the folding and storage of the whole photovoltaic module 10. On the other hand, according to the illumination conditions of the device application site and the like, the included angle between the first photovoltaic panel 11 and each second photovoltaic panel 12 can be adjusted within a preset angle range, so that the photovoltaic module 10 can receive sunlight within a space range to the maximum extent, and the adjustment mode can be selected according to the actual situation; for example, the included angle between two photovoltaic panels is adjusted and set in advance in a manual operation mode; for another example, the rotating shaft may be coupled to an output end of a power component such as a motor, and an included angle between the two photovoltaic panels may be automatically and adaptively adjusted according to a direction of sunlight under the cooperation of a matching sensing element (e.g., a photosensitive element).

Correspondingly, the number of the light-gathering components 40 is two, and the light-gathering components are respectively positioned on the first side of the first photovoltaic panel 11; in specific implementation, after the first photovoltaic panel 11 and the second photovoltaic panel 12 are relatively unfolded, the light-gathering component 40 may be fixed on the electricity storage component 20 (specifically, the carrier body 21) in an interposed manner, so that a certain included angle is maintained between a light-gathering surface of the light-gathering component 40 and a light-sensing surface of the first photovoltaic panel 11, so that sunlight is reflected and gathered on the first photovoltaic panel 11 by the light-gathering component 40, and a larger electric energy is obtained by enhancing a photoelectric conversion effect of the first photovoltaic panel 11. Of course, the light-focusing assembly 40 can also be rotatably mounted on the power storage assembly 20 by referring to the second photovoltaic panel 12; firstly, the photovoltaic panel can be folded, stored or unfolded with the first photovoltaic panel 11 and the second photovoltaic panel 12 for use; secondly, the included angle between the light-gathering surface of the light-gathering component 40 and the light-sensing surface of the photovoltaic panel can be adjusted within the preset angle range.

In another embodiment, there may be a plurality of, for example, four second photovoltaic panels 12, each of the plurality of second photovoltaic panels 12 is rotatably mounted on the power storage module 20 and is respectively located at four sides of the first photovoltaic panel 11, and through the selective arrangement of the rotating structure of each second photovoltaic panel 12, when the solar device is carried, transported or stored, the second photovoltaic panels 12 can be sequentially turned over and sequentially stacked on the photosensitive surface side of the first photovoltaic panel 11, so as to fold and store the photovoltaic device 10; in this case, the light collecting means 40 may be provided on the side of each second photovoltaic panel 12 (e.g., the side away from the first photovoltaic panel 11), and the sunlight may be collected by the light collecting means 40.

In one embodiment, referring to fig. 5 and 6, the photovoltaic module 10 further includes a positioning latch 13, which is mainly used to lock the second photovoltaic panel 12 in an unfolded state with the first photovoltaic panel 11; the positioning locking piece 13 is substantially a strip-shaped sheet structure, one end of the positioning locking piece is rotatably connected to the electric power storage assembly 20 (specifically, the bearing main body 21) at the corner of the first photovoltaic panel 11, the other end of the positioning locking piece is provided with a first clamping structure 13-1, and correspondingly, a second clamping structure 12-1 which is in contraposition fit with the first clamping structure 13-1 is arranged at the side of the second photovoltaic panel 12; when the photosensitive surface of the second photovoltaic panel 12 is rotated to a position in the same plane as the photosensitive surface of the first photovoltaic panel 11, the position of the second photovoltaic panel 12 is locked by the alignment and matching relationship between the first locking structure 13-1 and the second locking structure 12-1, so that the photovoltaic module 10 is stably maintained in the unfolded state. Of course, the number of the first clamping structures 13-1 or the number of the second clamping structures 12-1 may be plural, so that when the positioning locking member 13 is used, the second photovoltaic panel 12 can be locked at a specific position within a preset angle range, and an included angle between the photosensitive surface of the second photovoltaic panel 12 and the photosensitive surface of the first photovoltaic panel 11 has a certain adjustability.

In another embodiment, the positioning locking piece 13 may also adopt other structural forms, such as a sleeve structure that can be detachably installed at the sides of the first photovoltaic panel 11 and the second photovoltaic panel 12, and after the two panels are relatively unfolded, the positioning locking piece 13 is clamped at a position between two adjacent photovoltaic panels, so as to keep the photovoltaic module in the unfolded state; in all respects, they are not described in detail herein.

In other embodiments, by taking the above structure as a reference, the positioning lock 13 can also be used to lock the second photovoltaic panel 12 in the position where the first photovoltaic panel 11 is in the stacked state, so as to prevent the photovoltaic module 10 from being accidentally unfolded when the solar device is carried and stored.
