Abstract

A wireless activator is used for a vehicle. The wireless activator includes a transmitting control module, a transmitting module, a receiving module, and a receiving control module. The transmitting control module is positioned in a main portion of the vehicle. The transmitting module is positioned in the main portion and electrically coupled to the transmitting control module. The receiving module is positioned in a movable portion of the vehicle. The receiving control module is positioned in the movable portion and electrically coupled to the receiving module. The wireless activator is used for wirelessly supplying electrical power to the movable portion, and controlling the movable portion move relative to the main portion. A vehicle using the wireless activator is also provided.

First claim

What is claimed is:

1. A wireless activator for a movable portion of a vehicle, the wireless activator comprising:
a transmitting control module positioned in a main portion of the vehicle;
a transmitting module positioned in the main portion of the vehicle and electrically coupled to the transmitting control module, and having a transmitting coil and a transmitting communication coil;
a receiving module positioned in the movable vehicle portion and having a receiving coil and a receiving communication coil; and
a receiving control module electrically coupled to the receiving module and positioned in the movable vehicle portion;
wherein, the transmitting control module is configured to generate a magnetic field in the transmitting coil causing the receiving coil to generate an inductive magnetic field and charging the receiving control module; and
wherein, when a move signal is initiated, the transmitting control module is configured to drive the transmitting communication coil to generate a magnetic field inducing the receiving communication coil to generate a magnetic field and transmit a move signal to the receiving control module to activate movement of the moving vehicle portion.

2. The wireless activator of claim 1 , wherein the transmitting coil is received in the first communication coil, and the transmitting coil and the first communication coil are homocentric.

3. The wireless activator of claim 1 , wherein the transmitting module further comprises a first fixing member positioned in the main portion, the transmitting coil and the first communication coil are positioned on the first fixing member.

4. The wireless activator of claim 3 , wherein the transmitting module further comprises a first shielding member fixed on the first fixing member, the transmitting coil and the first communication coil are positioned on the first fixing member via the first shielding member.

5. The wireless activator of claim 4 , wherein the transmitting module further comprises a first housing fixedly coupled to the first fixing member, the first shielding member, the transmitting coil, and the first communication coil are received in the first housing.

6. The wireless activator of claim 5 , wherein the first housing comprises two mounting portions and a connection portion coupled between the two mounting portions, the two mounting portions are coupled with the first fixing member, the connection portion and the first fixing member cooperatively form a first receiving space, and the first shielding member, the transmitting coil, and the first communication coil are received in the first receiving space.

7. The wireless activator of claim 1 , wherein the receiving coil is received in the second communication coil, the receiving coil and the second communication coil are homocentric.

8. The wireless activator of claim 1 , wherein the receiving module further comprises a second fixing member positioned in the movable portion, the receiving coil and the second communication coil are positioned on the second fixing member.

9. The wireless activator of claim 8 , wherein the receiving module further comprises a second shielding member fixed on the second fixing member, the receiving coil and the second communication coil are positioned on the second fixing member via the second shielding member.

10. The wireless activator of claim 9 , wherein the receiving module further comprises a second housing fixedly coupled to the second fixing member, the second shielding member, the receiving coil, and the second communication coil are received in the second housing.

11. The wireless activator of claim 10 , wherein the second housing comprises two mounting portions and a connection portion coupled between the two mounting portions, the mounting portions are coupled with the second fixing member, the connection portion and the second fixing member cooperatively form a second receiving space, and the second shielding member, the receiving coil, and the second communication coil are received in the second receiving space.

12. A vehicle, comprising:
a main portion;
a transmitting control module positioned in the main portion;
a movable portion movably coupled to the main portion, and
a wireless activator, comprising:
a transmitting control module positioned in a main portion of the vehicle;
a transmitting module positioned in the main portion of the vehicle and electrically coupled to the transmitting control module, and having a transmitting coil and a transmitting communication coil;
a receiving module positioned in the movable vehicle portion and having a receiving coil and a receiving communication coil; and
a receiving control module electrically coupled to the receiving module and positioned in the movable vehicle portion;
wherein, the transmitting control module is configured to generate a magnetic field in the transmitting coil causing the receiving coil to generate an inductive magnetic field and charging the receiving control module; and
wherein, when a move signal is initiated, the transmitting control module is configured to drive the transmitting communication coil to generate a magnetic field inducing the receiving communication coil to generate a magnetic field and transmit a move signal to the receiving control module to activate movement of the moving vehicle portion.

13. The vehicle of claim 12 , wherein the transmitting coil is received in the first communication coil, and the transmitting coil and the first communication coil are homocentric.

14. The vehicle of claim 12 , wherein the transmitting module further comprises a first fixing member positioned in the main portion, the transmitting coil and the first communication coil are positioned on the first fixing member.

15. The vehicle of claim 14 , wherein the transmitting module further comprises a first shielding member fixed on the first fixing member, the transmitting coil and the first communication coil are positioned on the first fixing member via the first shielding member.

16. The vehicle of claim 15 , wherein the transmitting module further comprises a first housing fixedly coupled to the first fixing member, the first shielding member, the transmitting coil, and the first communication coil are received in the first housing.

17. The vehicle of claim 16 , wherein the first housing comprises two mounting portions and a connection portion coupled between the two mounting portions, the two mounting portions are coupled with the first fixing member, the connection portion and the first fixing member cooperatively form a first receiving space, and the first shielding member, the transmitting coil, and the first communication coil are received in the first receiving space.

18. The vehicle of claim 12 , wherein the receiving coil is received in the second communication coil, the receiving coil and the second communication coil are homocentric.

19. The vehicle of claim 12 , wherein the receiving module further comprises a second fixing member positioned in the movable portion, the receiving coil and the second communication coil are positioned on the second fixing member.

20. The vehicle of claim 19 , wherein the receiving module further comprises a second shielding member fixed on the second fixing member, the receiving coil and the second communication coil are positioned on the second fixing member via the second shielding member.
