Abstract

A smart electric meter is provided. The smart electric meter includes a body, an antenna holder, an antenna structure and a supporting member. The antenna holder is disposed on the body, wherein the antenna holder is annular. The antenna structure is disposed on the antenna holder, wherein the antenna structure is moveable along a circumferential direction of the antenna holder. The supporting member is connected to the antenna structure, wherein the supporting member is moveably disposed on the antenna holder, and the supporting member moves the antenna structure along the circumferential direction of the antenna holder.

First claim

What is claimed is:

1. A smart electric meter, comprising:
a body of the smart electric meter;
an antenna holder, disposed on the body, wherein the antenna holder is annular;
an antenna structure, disposed on the antenna holder, wherein the antenna structure is moveable along a circumferential direction of the antenna holder; and
a supporting member, connected to the antenna structure, wherein the supporting member is moveably disposed on the antenna holder, and the supporting member moves the antenna structure along the circumferential direction of the antenna holder,
wherein the supporting member comprises a positioning post, a positioning hole is formed on the antenna structure, and the positioning post passes through the positioning hole to connect the supporting member to the antenna structure.

2. The smart electric meter as claimed in claim 1 , wherein the antenna holder comprises a first surface, and the antenna structure is sandwiched between the first surface and the supporting member.

3. The smart electric meter as claimed in claim 2 , wherein the antenna holder further comprises a second surface and a first edge, and the first surface is opposite to the second surface, the first edge is located between the first surface and the second surface, the supporting member further comprises a hook, and the hook abuts the first edge and the second surface to hang the supporting member on the antenna holder.

4. The smart electric meter as claimed in claim 3 , wherein the first surface is an outer surface of the antenna holder, and the second surface is an inner surface of the antenna holder.

5. The smart electric meter as claimed in claim 1 , wherein the supporting member further comprises a rod, and an extending direction of the rod is opposite to an extending direction of the post, and when the rod is pushed, the supporting member pushes the antenna structure to slide along a peripheral direction of the antenna holder.

6. The smart electric meter as claimed in claim 5 , further comprising a cover, wherein the cover covers the antenna holder, the antenna structure and the supporting member, and the cover comprises a groove, and the rod passes through the groove and is projected over an outer surface of the cover.

7. The smart electric meter as claimed in claim 1 , wherein the antenna structure comprises a flexible substrate and a dipole antenna, and the dipole antenna is formed on the flexible substrate.

8. The smart electric meter as claimed in claim 7 , wherein the dipole antenna comprises a first radiator and a second radiator, and the first radiator is symmetrical to the second radiator and relative to a central line.

9. A smart electric meter, comprising:
a body of the smart electric meter;
an antenna holder, disposed on the body, wherein the antenna holder is annular;
an antenna structure, disposed on the antenna holder, wherein the antenna structure is moveable along a circumferential direction of the antenna holder;
a supporting member, connected to the antenna structure, wherein the supporting member is moveably disposed on the antenna holder, and the supporting member moves the antenna structure along the circumferential direction of the antenna holder; and
an actuator and a transmission mechanism, wherein the actuator is connected to the transmission mechanism, and the transmission mechanism is connected to the antenna holder, and the actuator actuates the transmission mechanism to move the supporting member to slide along a peripheral direction of the antenna holder.

10. The smart electric meter as claimed in claim 9 , wherein the transmission mechanism is a gear wheel, and the supporting member comprises a rack, and the gear wheel is engaged with the rack, and when the transmission mechanism is rotated, the supporting member is moved by the transmission mechanism and slid along the peripheral direction of the antenna holder.

11. The smart electric meter as claimed in claim 10 , wherein the antenna holder further comprises a first surface, a second surface and a first edge, and the first surface is opposite to the second surface, the first edge is located between the first surface and the second surface, and the antenna structure is sandwiched between the first surface and the supporting member.

12. The smart electric meter as claimed in claim 11 , wherein the rack corresponds to the second surface, and the antenna holder surrounds the actuator and the transmission mechanism.

13. The smart electric meter as claimed in claim 11 , wherein the supporting member further comprises a hook, and the hook abuts the first edge and the second surface to hang the supporting member on the antenna holder, wherein the rack is connected to the hook.

14. The smart electric meter as claimed in claim 13 , wherein the first surface is an outer surface of the antenna holder, and the second surface is an inner surface of the antenna holder.

15. The smart electric meter as claimed in claim 9 , wherein the antenna structure comprises a flexible substrate and a dipole antenna, and the dipole antenna is formed on the flexible substrate.

16. The smart electric meter as claimed in claim 15 , wherein the dipole antenna comprises a first radiator and a second radiator, and the first radiator is symmetrical to the second radiator and relative to a central line.
