The subject matter herein generally relates to buoyancy devices and portable electronic assemblies using the same.
With the improvement of wireless communication, portable electronic devices have become important tools in daily life. But the portable electronic devices are easily damaged when dropped into water or other liquid.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. The term “comprising” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
The buoyancy device 50 can be a protection case made of plastic material or silica gel.
It is to be understood, the buoyancy device 50 can be made of other materials with low density. For example, when the buoyancy device 50 is designed to enable the portable electronic device 90 to float on a kind of liquid, the density of the buoyancy device 50 should be low enough such that the overall density of the portable electronic assembly 100 is lower than the density of that kind of liquid.
The second primary cavity 533 is disposed outside of the first primary cavity 531. The second primary cavity 533 includes at least two isolated second subsidiary cavities 5331. As illustrated in
Although the cavity 53 is illustrated as a honey comb structure in
In assembly, the buoyancy device 50 can be made by injection molding in a gas chamber and the gas in the chamber can be nitrogen, helium or other gas with low density, thus the gas with low density can be filled in the first primary cavity 531 and the second primary cavity 533, then the portable electronic device 90 can be accommodated in the accommodation cavity 515. Alternatively, the buoyancy device 50 can be made by injection molding in a vacuum chamber. When the portable electronic device 90 and buoyancy device 50 are dropped to the ground, the separating plates 5313 and supporting plates 5333 can support the buoyancy device 50 and the portable electronic device 90 to prevent the portable electronic device 90 from being broken by impact force. When the buoyancy device 50 and the portable electronic device 90 are dropped into liquid, the gas in the first primary cavity 531 and the second primary cavity 533 can improve the buoyancy force of the buoyancy device 50 to make the portable electronic device 90 float on the liquid, thereby preventing the portable electronic device 90 from being submerged under the water or other liquid, thus limiting the amount of liquid that enters the portable electronic device 90.
It is to be understood, in other embodiments, the buoyancy device 150 can be a whole housing of the portable electronic device 190 or a partial housing of the portable electronic device 190.
In summary, the buoyancy device 50 defines the first primary cavity 531 and the second primary cavity 533 between the bottom board 511 and the side boards 513 which can be filled with low density gas, thereby improving the buoyancy force of the buoyancy device 50. The first primary cavity 531 is substantially a honeycomb structure and includes a plurality of first subsidiary cavities 5311, the second primary cavity 533 includes a plurality of second subsidiary cavities 5331, when any one of the first subsidiary cavities 5311 and the second subsidiary cavities 5331 is damaged, other first subsidiary cavities 5311 and second subsidiary cavities 5331 can still function. The first primary cavity 531 has a plurality of separating plates 5313, the second primary cavity 533 has a plurality of supporting plates 5333, the separating plates 5313 and the supporting plates 5333 are connected to strengthen the cavity 53 of the buoyancy device 50.
The embodiments shown and described above are only examples. Many details are often found in the art. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
