Abstract

A charging system is provided, including a charging device and an electronic device. The charging device includes a housing, a metal connector, a power supply source electrically connected to the metal connector, a first magnetic member, and a second magnetic member. The electronic device includes a main body, a power storage member, an electronic contact electrically connected to the power storage member, and a third magnetic member. The third magnetic member has a first surface and a second surface adjacent to the first surface. When the electronic device is disposed on the charging device, the metal connector contacts the electronic contact, the first surface faces the first magnetic member, and the second surface faces the second magnetic member.

Claims

1. A charging system, comprising:

a charging device, comprising;

a housing;

a metal connector, disposed on the housing;

a power supply, electrically connected to the metal connector;

a first magnetic member, disposed on the housing; and

a second magnetic member, disposed on the housing; and

an electronic device, detachably disposed on the charging device, comprising;

a main body;

a power storage member, disposed on the main body;

an electronic contact, disposed on the main body and electrically connected to the power storage member; and

a third magnetic member, disposed on the main body, having a first surface and a second surface adjacent to the first surface, wherein when the electronic device is disposed on the charging device, the metal connector contacts the electronic contact, the first surface faces the first magnetic member, and the second surface faces the second magnetic member.

2. The charging system as claimed in claim 1, wherein the main body comprises a recess, and the first magnetic member protrudes from a surface of the housing, wherein when the electronic device is disposed on the charging device, at least a portion of the first magnetic member is accommodated in the recess.

3. The charging system as claimed in claim 1, wherein the housing comprises a depression, and the third magnetic member protrudes from a lateral surface of the main body, wherein when the electronic device is disposed on the charging device, at least a portion of the third magnetic member is accommodated in the depression.

4. The charging system as claimed in claim 1, wherein when the electronic device is disposed on the charging device, the distance between the central axis of the second magnetic member and the first magnetic member is shorter than the distance between the central axis of the third magnetic member and the first magnetic member.

5. The charging system as claimed in claim 4, wherein the third magnetic member has a predetermined length, and when the electronic device is disposed on the charging device, the distance between the central axis of the second magnetic member and the central axis of the third magnetic member is ½

-⅕

of the predetermined length.

6. The charging system as claimed in claim 1, wherein when the electronic device is disposed on the charging device, the S pole of the first magnetic member faces the N pole of the third magnetic member, and the S pole of the second magnetic member and the N pole of the third magnetic member face a surface of the housing.

7. The charging system as claimed in claim 1, wherein when the electronic device is disposed on the charging device, the N pole of the first magnetic member faces the S pole of the third magnetic member, and the N pole of the second magnetic member and the S pole of the third magnetic member face a surface of the housing.

8. The charging system as claimed in claim 1, wherein when the electronic device is disposed on the charging device, the first magnetic member is aligned with the third magnetic member.

9. The charging system as claimed in claim 1, wherein the electronic device further comprises a film, when the electronic device is disposed on the charging device, the film is disposed between the first magnetic member and the third magnetic member.

10. The charging system as claimed in claim 1, wherein the power supply is a rechargeable battery or an external power source.
