Abstract

A case for an electronic device includes a first housing, a second housing, a support and a sealing ring. The first housing has a first surface and a second surface that together form an accommodation portion. The second surface is connected to the first surface, and the second surface surrounds the first surface. The second housing is disposed in the accommodation portion. The second housing has a third surface and a fourth surface connected to each other. The third surface faces the first surface, and the fourth surface faces the second surface. The support is disposed between the first surface and the third surface for keeping a distance between the first surface and the third surface. The sealing ring is squeezed between the second surface and the fourth surface, and the sealing ring seals the accommodation portion.

Claims

1. A case for an electronic device, comprising:

a first housing having a first surface and a second surface that together form an accommodation portion, the second surface connected to the first surface, and the second surface surrounding the first surface;

a second housing disposed in the accommodation portion, the second housing having a third surface and a fourth surface that are connected to each other, the third surface facing the first surface, and the fourth surface facing the second surface;

a support disposed between the first surface and the third surface for keeping a distance between the first surface and the third surface; and

a sealing ring squeezed between the second surface and the fourth surface, and the sealing ring sealing the accommodation portion.

2. The case according to claim 1, wherein the second surface of the first housing comprises a groove, a part of the sealing ring is disposed in the groove, and the other part of the sealing ring is protruded from the second surface and is pressed against the fourth surface of the second housing.

3. The case according to claim 1, wherein the fourth surface of the second housing comprises a groove, a part of the sealing ring is disposed in the groove, and the other part of the sealing ring is protruded from the fourth surface and is pressed against the second surface of the first housing.

4. The case according to claim 3, wherein an orthogonal projection of the groove on the third surface of the second housing and an orthogonal projection of the support on the third surface are not overlapped with each other.

5. The case according to claim 3, wherein the sealing ring comprises a circular body and a plurality of protrusions disposed on the circular body, the plurality of protrusions surrounds a side surface of the circular body facing the second surface of the first housing and are parallel to each other;

the circular body is disposed in the groove, the plurality of protrusions protrudes from the groove and is compressed by the second surface of the first housing.

6. The case according to claim 1, wherein the support and the second housing are integrally formed.

7. The case according to claim 1, wherein the support and the first housing are integrally formed.

8. The case according to claim 7, further comprising a reinforcement component, and two sides of the reinforcement component that are opposite to each other being connected to the second surface of the first housing and the support, respectively.

9. The case according to claim 8, wherein the reinforcement component abuts against the third surface of the second housing.

10. The case according to claim 1, wherein the second housing further has a display surface, the third surface and the display surface are opposite to each other, and the display surface is perpendicular to the second surface of the first housing.
