TECHNICAL FIELD
The disclosure generally relates to cases, and particularly, to a protection case for an electronic device.
DESCRIPTION OF RELATED ART
Generally, handheld electronic devices do not have a stand for supporting the electronic device. A user has to hold the electronic device in a certain desired orientation. However, to hold the electronic device for a long time can be uncomfortable.
Therefore, it is desirable to provide a means which can overcome the above-mentioned problems.
BRIEF DESCRIPTION OF THE DRAWINGS
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the views.
FIG. 1 is an isometric, assembled view of a protection case and an electronic device in accordance with an exemplary embodiment.
FIG. 2 is an isometric, cross-sectional view of the protection case of FIG. 1, taken along line II-II.
FIG. 3 is an isometric, exploded view of the protection case of FIG. 1.
FIG. 4 is a cutaway view of the protection case of FIG. 3, showing a number of adjusting balls in a first adjustable sidewall of the protection case.
FIG. 5 is similar to FIG. 4, but showing the adjusting balls in a second adjustable sidewall of the protection case.
DETAILED DESCRIPTION
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references can mean “at least one.”
In FIGS. 1-3, a protection case 1 for an electronic device 2 in accordance with an exemplary embodiment includes a baseboard 10, a sidewall 12, and a number of adjusting balls 14. The sidewall 12 extends from a periphery of the baseboard 10. The adjusting balls 14 are received inside the sidewall 12. The baseboard 10 defines a receiving space 16 in cooperation with the sidewall 12 to receive the electronic device 2. The baseboard 10 and the sidewall 12 are hollow. The baseboard 10 and a part of the sidewall 12 are filled with gas having a density less than air. Thus, the protection case 1 with received the electronic device 2 is suspended in the air via a buoyancy generated by a difference in density between the gas and the air. The adjusting balls 14 roll in the sidewall 12 along different directions to adjust an orientation of the protection case 1. In this embodiment, the electronic device 2 is a mobile intelligent terminal, such as, a smart phone or a tablet computer.
FIGS. 3 and 4 show that the baseboard 10 has a predetermined thickness and is hollow inside to accommodate the gas. The sidewall 12 extends from the periphery of the baseboard 10 towards a same direction. The sidewall 12 includes a filling sidewall 120 and an adjustable sidewall 122. The filling sidewall 120 communicates with the baseboard 10. The filling sidewall 120 includes a valve 121 to expend the gas. The adjustable sidewall 122 is isolated from the baseboard 10 by a barrier 124. The adjustable sidewall 122 includes at least two parts 122a, 122b correspondingly extending along different directions and a baffle plate 125 set at a turning corner between two adjacent parts 122a, 122b of the adjustable sidewall 122. The adjusting balls 14 are received in the adjustable sidewall 122 and roll along the adjustable sidewall 122. The adjustable sidewall 122 defines a through hole 1250 in the baffle plate 125. The adjusting balls 14 are transferred between the different parts 122a, 122b of the adjustable sidewall 122 by passing through the through hole 1250. Thus, a center of gravity of the protection case 1 is adjusted according to a distribution of the number of the adjusting balls 14 in the different parts 122a, 122b of the adjustable sidewall 122, and the suspending protection case 1 can allow for different positionings.
In this embodiment, the baseboard 10 is rectangular. The different parts 122a, 122b of the adjustable sidewall 122 are a first adjustable sidewall 122a extending along a width of the protection case 1 and a second adjustable sidewall 122b extending along a length of the protection case 1. The first adjustable sidewall 122a is directly adjacent to the second adjustable sidewall 122b. The adjustable sidewall 122 is not inflated with the gas. In the other embodiment, the adjustable sidewall 122 can be filled with the gas.
FIGS. 4 and 5 show that in use, the electronic device 2 is received in the receiving space 16 of the protection case 1. The gas is filled in the filling sidewall 120 and the baseboard 10 via the valve 121. In this embodiment, the gas is hydrogen. The buoyancy forced in the protection case 1 filled with the gas is substantially equal to a summation of gravity of the protection case 1. The electronic device 2, and the adjusting balls 14, are suspended in the air in the protection case 1. The adjusting balls 14 roll along the adjustable sidewall 122 when the protection case 1 is rotated adjusting the distribution of the adjusting balls 14 in the adjustable sidewall 122. Thus, the posture of the suspending protection case 1 is changed according to the distribution of the number of the adjusting balls 14 in the adjustable sidewall 122. For example, when the adjusting balls 14 stay in the first adjustable sidewall 122a, the protection case 1 is inclined with the first adjustable sidewall 122a facing downwards and the filling sidewall 120 parallel opposite to the first adjustable sidewall 122a facing upwards. When the adjusting balls 14 stay in the second adjustable sidewall 122b, the protection case 1 is inclinded with the second adjustable sidewall 122b facing downwards and the filling sidewall 120 parallel opposite to the second adjustable sidewall 122b.
The hollow protection case 1 is inflated with gas lighter than air gas to hold the electronic device 2 suspended in the air, which relieves fatigue of holding the electronic device 2 by hand for a long time.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments.
