Abstract

The present invention provides an electronic device with automatic positioning function, which includes a device body and a magnetic unit. The device body contains therein a wireless transmission module. The wireless transmission module includes a transmission coil. The device body has one side in which a receiving section is formed. The transmission coil is received in the receiving section. The transmission coil has an outer circumference that is spaced from an inner circumference of the receiving section by a movement distance. The magnetic unit is set at the center of the transmission coil.

Claims

1. An electronic device with automatic positioning function, comprising:

a device body, which comprises a wireless transmission module, the wireless transmission module comprising a transmission coil, the device body having one side that comprises a receiving section formed therein, the transmission coil being received in the receiving section, the transmission coil having an outer circumference that is spaced from an inner circumference of the receiving section by a movement distance; and

a magnetic unit, which is set in center of the transmission coil.

2. The electronic device with automatic positioning function as claimed in claim 1, wherein the wireless transmission module and the transmission coil are connected to each other by at least two first conductive wires arranged therebetween, each of the first conductive wires being formed by twisting multiple strands of threads.

3. The electronic device with automatic positioning function as claimed in claim 1, wherein the receiving section of the device body movably receives therein a disk, the disk having a surface forming a central receiving chamber and a circumferential receiving chamber that circumferentially surrounds the central receiving chamber, the central receiving chamber receiving therein the magnetic unit, the circumferential receiving chamber receiving therein the transmission coil.

4. The electronic device with automatic positioning function as claimed in claim 3, wherein the disk has an opposite surface on which a plurality of spot bumps is formed, the spot bumps providing slidable engagement with a surface of the receiving section.

5. The electronic device with automatic positioning function as claimed in claim 3, wherein the magnetic unit comprises a first magnetic attraction element having positive polarity facing outward and a second magnetic attraction element having negative polarity facing outward, the first and second magnetic attraction elements being laid flat and jointed to each other to form a shape of disk, the magnetic unit being rotatably received in the central receiving chamber of the disk.

6. The electronic device with automatic positioning function as claimed in claim 5, wherein the central receiving chamber of the disk comprises an annulus of projecting flange along a circumference thereof, the projecting flange constraining the magnetic unit within the central receiving chamber.

7. The electronic device with automatic positioning function as claimed in claim 5, wherein the central receiving chamber of the disk receives a rotatable rotation shaft arranged therein, the rotation shaft being fixedly fit into a center of the magnetic unit.

8. The electronic device with automatic positioning function as claimed in claim 7, wherein the central receiving chamber of the disk comprises a bearing fit therein, an end of the rotation shaft being fixedly fit into the bearing for free rotation, an opposite end of the rotation shaft being fixedly fit into the center of the magnetic unit.

9. The electronic device with automatic positioning function as claimed in claim 5, wherein the central receiving chamber of the disk comprises a vertically extending raised post, the center of the magnetic unit being provided with a bearing, the bearing being fit over the raised post.

10. The electronic device with automatic positioning function as claimed in claim 3, wherein the magnetic unit comprises a magnetism conduction member and an electromagnetic coil, the electromagnetic coil being wound around the magnetism conduction member and being fixed together in the central receiving chamber of the disk.

11. The electronic device with automatic positioning function as claimed in claim 10, wherein the electromagnetic coil is connected to two second conductive wires, each of the second conductive wires being formed by twisting multiple strands of threads.
