Abstract

A protecting case for protecting an electronic device from external impact includes a hollow main body filled with water and a number of buffering modules received in the main body. The electronic device is received in the main body. The buffering modules are deformed to release active metal powder into the water when the main body falls to the ground. The active metal powder is a chemical that reacts with water to generate hydrogen gas.

Claims

1. A protection case for an electronic device, comprising:

a hollow baseboard;

a hollow sidewall extending from a periphery of the baseboard towards a same direction and defining a receiving space in cooperation with the baseboard to receive the electronic device; and

at least one buffering module received in the baseboard and the sidewall;

wherein the hollow baseboard and the sidewall are filled with water, and the at least one buffering module releases active metal powder into the water when the protection case is impacted by an external force.

2. The protection case of claim 1, wherein the baseboard comprises an inner side surface and an outer side surface parallel opposite to the inner side surface, the receiving space is defined by the inner side surface, and the protection case defines a plurality of first receiving holes in the outer side surface to receive the at least one buffering modules.

3. The protection case of claim 2, wherein the sidewall comprises a top surface parallel to the outer side surface of the baseboard, and the sidewall defines a plurality of second receiving holes in the top surface to receive the at least one buffering modules.

4. The protection case of claim 3, wherein the baseboard is rectangular, and the second receiving holes are defined corresponding to four corners of the protection case.

5. The protection case of claim 3, wherein each buffering module comprises a hollow receiving body stuck in the first receiving holes or the second receiving holes, a spring received in the receiving body, and a first plate, the receiving body defines an opening at a bottom of the receiving body, the active metal powder is filled in the receiving body via the opening, and the first plate is pulled to block the opening via a restoring force provided by the spring.

6. The protection case of claim 5, wherein the at least one buffering module further comprises a second plate and a holding arm, the holding arm comprises a fixing end connected to an inner side of the sidewall and a free end connected to the second plate, the first plate and the second plate are made of magnetic material, and the second plate is attracted to the first plate via a magnetic force.

7. The protection case of claim 1, wherein the active metal powder is selected from the group consisting of sodium, magnesium, and potassium.

8. A case for an electronic device, comprising:

a hollow main body covering at least a portion of the electronic device; and

a plurality of buffering modules received in the main body;

wherein the main body is filled with water, each buffering module is deformed to release active metal powder into the water when the main body is impacted by an external force, the active metal powder chemically reacts with the water to generate hydrogen gas, and the external force applied to the main body by the ground is buffered via a buoyancy generated by a difference in density between the hydrogen gas and the air.

9. The case of claim 8, wherein the main body comprises a hollow baseboard and a hollow sidewall extending from a periphery of the baseboard towards a same direction, and the electronic device is accommodated in a receiving space defined by the baseboard in cooperation with the sidewall.

10. The case of claim 9, wherein the baseboard includes an inner side surface and an outer side surface parallel opposite to the inner side surface, the receiving space is defined by the inner side surface, and the case defines a plurality of first receiving holes in the outer side surface to receive the buffering modules.

11. The case of claim 10, wherein the sidewall comprises a top surface parallel to the outer side surface of the baseboard, and the sidewall defines a plurality of second receiving holes in the top surface to receive the buffering modules.

12. The case of claim 11, wherein the baseboard is rectangular, and the second receiving holes are defined corresponding to four corners of the case.

13. The case of claim 11, wherein each buffering module comprises a hollow receiving body stuck in the first receiving holes or the second receiving holes, a spring received in the receiving body, and a first plate, the receiving body defines an opening at a bottom of the receiving body, the active metal powder is filled in the receiving body via the opening, and the first plate is pulled to block the opening via a restoring force provided by the spring.

14. The case of claim 13, wherein the buffering modules further comprise a second plate and a holding arm, the holding arm comprises a fixing end connected to an inner side of the sidewall and a free end connected to the second plate, the first plate and the second plate are made of magnetic material, and the second plate is attracted to the first plate via a magnetic force.

15. The case of claim 8, wherein the active metal powder is selected from the group consisting of sodium, magnesium, and potassium.
