In some embodiments, on battery capacity indication lamp side, control circuit board, button is provided with.Structure is simple, easy to use, when user needs to know battery dump energy how many time, only need detect battery dump energy by button control control circuit board and shown the battery condition of batteries by many battery capacity indication lamps, user can know the dump energy of battery intuitively thus selects charging or continue to use.
In some embodiments, be provided with the charging inlet with external solar panels adaptation on button side, control circuit board, charging inlet is past from the side of shell to be exposed outside.Thus, a kind of solar energy lantern can utilize solar panels to charge to battery, convenient and swift, environmental protection and energy saving of charging.
In some embodiments, on button side, control circuit board, be provided with USB interface, USB interface is past from the side of shell to be exposed outside.By USB interface, this solar energy lantern can be the Move tool chargings such as mobile phone as portable power source.And under the condition being unfavorable for solar panels work at the cloudy day etc., external power source can be used to be charged to battery by USB interface
In some embodiments, the lateral surface of shell is provided with pit, described battery capacity indication lamp, button, charging inlet and USB interface are all positioned at inside described pit.Pit has protective effect, effectively avoids other objects to touch button easily and causes maloperation, improves the reliability that product uses.Groove has identification effect simultaneously, makes user be touched can be recognized button position by hand, the use of person easy to use.
In some embodiments, described shell is spliced by 2 housings, and described shell centrally line is provided with some belt holes for installing belt.Structure is simple, shell easy to assembly, and shell remains for the belt hole of installing belt in advance, and user can increase belt according to actual needs on shell, more convenient to carry and use.
In some embodiments, the medial surface of 1 housing is wherein provided with locating dowel, and the medial surface of another 1 housing is provided with locating hole, and when 2 housings are stitched together, described locating dowel embeds inside described locating hole.Structure is simple, facilitates the location and installation between 2 housings, improves packaging efficiency, saves human cost.
In some embodiments, on the medial surface of locating hole side, housing, be provided with the slot for installing described battery.Structure is simple, facilitates the location and installation of battery, and make the installation of battery firmly, can not get loose easily.
In some embodiments, on the medial surface of side, described slot, housing, lug is provided with for fixing described battery.Structure is simple, effectively battery is fixed on housings, make the installation of battery firmly, can not get loose easily.
