Abstract

A case for an electronic device wherein the electronic device has a receiver coil for wireless charging and the receiver coil is formed in between an inner circle and an outer circle, includes: a hard protective frame constructed to receive the electronic device therein wherein the hard protective frame has a recess which faces the electronic device; and a metal plate constructed to be received in the recess. The metal plate is constructed to enable magnetic retention or attachment of the case to a support having a magnet. The metal plate has a rounded concave edge, and the metal plate does not overlap with the inner circle. Preferably, the rounded concave edge, the inner circle, and the outer circle are substantially symmetrical with respect to a same line.

Claims

1. A case (100) for an electronic device (300) wherein the electronic device (300) has a receiver coil (310) for wireless charging and the receiver coil (310) is formed in between an inner boundary (320) and an outer boundary (330), the case comprising:

a hard protective frame (20) constructed to receive the electronic device (300) therein wherein the hard protective frame (20) has a recess (26) which faces the electronic device (300); and

a metal plate (30) constructed to be received in the recess (26) of the hard protective frame (20),

wherein the metal plate (30) is constructed to enable magnetic retention or attachment of the case (100) to a support (40) having a magnet (50),

wherein the metal plate (30) has a rounded concave edge (35),

wherein the metal plate (30) received in the recess (26) is constructed not to substantially block magnetic waves passing through the area formed by the inner boundary.

2. The case of claim 1, wherein the metal plate (30) does not overlap with an orthographic parallel projection of the area formed by the inner boundary (320) onto a projection plane of the metal plate (30).

3. The case of claim 1, wherein the inner boundary (320) and the outer boundary (330) are substantially circular.

4. The case of claim 1, wherein the rounded concave edge (35) substantially symmetrically aligns to respective orthographic parallel projections of the inner boundary (320) and the outer boundary (330) onto a projection plane of the metal plate (30).

5. The case of claim 4, wherein the rounded concave edge (35) at least partially overlaps with an orthographic parallel projection of the outer boundary (330) onto a projection plane of the metal plate (30).

6. The case of claim 4, wherein the rounded concave edge (35) is placed outside an orthographic Parallel projection of the outer boundary (330) onto a projection plane of the metal plate (30).

7. The case of claim 1, wherein the metal plate (30) is substantially rectangular with a first side (34) having the rounded concave edge (35),

wherein the metal plate (30) has third and fourth sides (31, 32) that are substantially parallel to each other and has a second side (33) that is substantially parallel to the first side (34).

8. The case of claim 7, wherein the metal plate (30) has rounded corners.

9. The case of claim 1, wherein the metal plate (30) is substantially trapezoidal wherein the rounded concave edge (35) is formed on a shorter side (34) of two parallel sides (33, 34), and wherein the metal plate (30) has rounded corners.

10. The case of claim 1, wherein the metal plate (30) is attached to the hard protective frame (20) by an adhesive (37).

11. The case of claim 1, wherein the hard protective frame (20) further comprises a surrounding recess (28) which surrounds the recess (26) and slopes away from a flat surface (23) of the hard protective frame (20) towards the recess (26) forming a cavity.

12. The case of claim 1, further comprising a soft protective cover (10) which comprises a back panel (12) to cover a back portion of the electronic device (300), and a side wall (14) extending from a top surface (11) of the back panel (12) along edges (13) of the back panel (12), wherein the hard protective frame (20) is constructed to removably mount over the soft protective cover (10).

13. A metal plate (30) for magnetically mounting an electronic device (300) or a case (100) with an electronic device (300) installed therein wherein the electronic device (300) has a receiver coil (310) for wireless charging and the receiver coil (310) is formed in between an inner boundary (320) and an outer boundary (330), the metal plate (30) comprising:

a rounded concave edge (35),

wherein the metal plate (30) is constructed to be attachable to the electronic device (300) or the case (100),

wherein the metal plate (30) is constructed to enable magnetic retention or attachment of the electronic device (300) to a support (40) having a magnet (50),

wherein the metal plate (30) attached to the electronic device (300) or the case (100) is constructed not to substantially block magnetic waves passing through the area formed by the inner boundary.

14. The case of claim 13, wherein the metal plate (30) does not overlap with an orthographic parallel projection of the area formed by the inner boundary (320) onto a projection plane of the metal plate (30).

15. The case of claim 13, wherein the inner boundary (320) and the outer boundary (330) are substantially circular.

16. The case of claim 13, wherein the rounded concave edge (35), the inner boundary (320), and the outer boundary (330) are substantially symmetrical with respect to a same line.

17. The case of claim 16, wherein the rounded concave edge (35) at least partially overlaps with an orthographic parallel projection of the outer boundary (330) onto a projection plane of the metal plate (30).

18. The case of claim 16, wherein the rounded concave edge (35) is placed outside an orthographic parallel projection of the outer boundary (330) onto a projection plane of the metal plate (30).

19. The case of claim 13, wherein the metal plate (30) is substantially rectangular with a first side (34) having the rounded concave edge (35), and the metal plate (30) has rounded corners,
