Self-balancing floating battery case

Abstract

A self-balancing floating battery case, comprising an upper casing and a lower casing, wherein the upper casing and the lower casing are connected by threads, a height of the upper casing is bigger than a height of the upper casing. A light opening is provided at an intermediate portion of the upper casing away from a center of the upper casing, a box surrounding the light opening is provided on an inner wall of the upper casing, the box is divided to be a PCB cavity and a battery cavity, a main body of the light opening deviates towards the PCB cavity and a main body of the battery cavity deviate towards the center of the upper casing. In the present invention, existing structures are modified, the battery case has a higher waterline, entrance of water can be prevented; and eccentricity of the center of gravity is corrected by weight.

A sealing ring 3 is provided between the upper casing 2 and the lower casing 1.

[0027] A ratio between the height of the upper casing 2 and the height of the lower casing 1 falls in a range of 1:2 to 1:4.

[0028] As shown in FIG. 2, a light opening 4 is provided at an intermediate portion of the upper casing 2, a light cover 5 is inserted in the light opening 4 and the light cover 5 is connected in the light opening 4 by sealing by glues.

[0029] A box 6 surrounding the light opening 4 is provided on an inner wall of the upper casing 2, wherein a cap 10 is provided at an outlet at a lower end portion of the box 6.

[0030] The box 6 is divided to be a PCB cavity 7 and a battery cavity 8, wherein a PCB board is provided in the PCB cavity 7 and a storage battery is provided in the battery cavity 8.

Embodiment 2

[0031] As shown in FIG. 3 and FIG. 4, a light opening 4 is provided at an intermediate portion of the upper casing 2 away from a center of the upper casing 2, a main body of the light opening 4 inclines towards the PCB cavity 7, and consequently, a main body of the battery cavity 8 inclines towards the center of the upper casing 2.

[0032] Other features are the same as those in embodiment 1.

Embodiment 3

[0033] A cableway 9 is provided beside the light opening 4 in the upper casing 2, wherein the cableway 9 is provided in the PCB cavity 7, a cable is introduced from the PCB board and the cable is connected with a pair of solar energy charger boards after passing through the cableway 9.

[0034] Other features are the same as those in embodiment 2.

[0035] Use of the battery case: in the present invention, the existing structures are slightly modified so that the battery case has a higher waterline, and entrance of water can be prevented; and eccentricity of the center of gravity is corrected by weight, so that the center of gravity is maintained on the central line of the battery case, overturning can be prevented, a floating position of the battery case is just and ornamental properties of the battery case can be higher.
