Abstract

An electronic device includes a charge receiving coupler. The charge receiving coupler includes a switching assembly and an inserting member. The switching assembly includes a gear transmission shaft, an elastic member, a first transmission wheel, a second transmission wheel fixed to the first transmission wheel, a button gear, and a button fixed to the button gear. The button gear engages with the first transmission wheel. The gear transmission shaft extends through the elastic member, the first transmission wheel and the second transmission wheel in that order. The inserting member defines a receiving groove, and the second transmission wheel is partly received in the receiving groove. The present disclosure further provides a power adapter which is matched with the charge receiving coupler.

First claim

What is claimed is:

1. A charge receiving coupler, comprising:
a switch assembly comprising a gear transmission shaft, a resilient element, a first driving wheel, a second driving wheel fixed to the first driving wheel, a button gear engaged with the first driving wheel, and a button fixed to the button gear; and
an inserting member adjacent to the switch assembly defining a receiving groove and the second driving wheel partly received in the receiving groove;
wherein the gear transmission shaft extends through the resilient element, the first driving wheel and the second driving wheel;
wherein a distance between the inserting member and a contacting surface of the second driving wheel is reduced gradually along the direction of insertion.

2. The charge receiving coupler of claim 1 , wherein the switch assembly further comprises a first base; wherein the resilient element, the first driving wheel and the button gear are received in the first base, and the second driving wheel partly received in the first base and the button fixed on the first base.

3. The charge receiving coupler of claim 2 , wherein the resilient element is arranged between an inner wall of the first base and the first driving wheel.

4. The charge receiving coupler of claim 1 , wherein the second driving wheel is a gear and comprises a first end and a second end opposite to the first end.

5. The charge receiving coupler of claim 4 , wherein the first end is a flat and engages with the first driving wheel, the second end is an inclined plane that causes the distance between the inserting member and the contacting surface of the second driving wheel becomes smaller gradually along the direction of insertion.

6. The charge receiving coupler of claim 1 , further comprising a case, wherein the switch assembly and the inserting member are received in the case, and the switch assembly is mounted on the inserting member.

7. The charge receiving coupler of claim 1 , wherein the button comprises a first body and a pair of convex lugs extended from two opposite sides of the first body of the button and each convex lug defines a fixing hole, and the button gear comprises a first recess perpendicular to the button gear and a second recess located opposite to the first recess.

8. The charge receiving coupler of claim 7 , wherein the switch assembly further comprises a button transmission shaft extending through the fixing hole, the first recess and the second recess, and the button gear partly received between the convex lugs.

9. A power adapter, comprising:
a body comprising a first cover, a second cover assembled together and a circuit unit mounted on the second cover, and the circuit unit used to transform alternating current to direct current;
a plug comprising a first transmission belt, a rotating switch located on an input end of the circuit unit to control the circuit unit on and off, and a second transmission belt wrapping around the rotating switch; and
two wires, one end of each wire connecting with the first transmission belt and an other end of each wire connecting with the second transmission belt;
wherein when the first transmission belt rotates, the second transmission belt rotates with the first transmission belt to turn on or off the rotating switch to control the circuit unit power on or off.

10. The power adapter of claim 9 , wherein the first transmission belt is a rack.

11. The power adapter of claim 9 , wherein the plug further comprises a second base and the first transmission belt is received in the second base.

12. The power adapter of claim 11 , wherein the second base comprises a second body comprising a first profile and a second profile located opposite to the first profile, and two installing grooves are defined on the first profile and the second profile.

13. The power adapter of claim 9 , further comprising a pair of conducting members, wherein one end of the conducting member respectively engages with the two wires and an other end of the conducting member respectively is fixed on the output end of the circuit unit.

14. The power adapter of claim 12 , wherein the second base further comprises an insulation sleeve connecting the second body of the second base with the body of the power adapter and comprises a fitting surface connecting the first profile to the second profile, a first groove is partly received in a second driving wheel extended from the fitting surface of the second base, a second groove is located adjacent to the insulation sleeve and communicates with the first groove, and the first transmission belt is partly received in the first groove and is partly received in the second groove; wherein the wires are partly received in the fixing sleeve, the second groove of the second base and the body of the power adapter.

15. The power adapter of claim 14 , wherein a third groove is defined in the fixing surface and communicates with the first groove, one side of the third groove comprises a plurality of first slots and a plurality of second slots, and an other side of the third groove comprises a plurality of first slots and a plurality of second slots on corresponding location.

16. The power adapter of the claim 9 , wherein the plug further comprises a movable element received in the third groove and an elastic element partly received in the movable element, two ends of the plug are retained to the first slots respectively to keep the movable element and the second body of the second base to remain relatively stable; when the movable element moves from the third groove to the first groove, the ends of the elastic element of the plug separate from the first slots and move with the movable element till the second slots, and the ends of the elastic element retain to the second slots to stop the movable element moving.

17. An electronic device, comprising:
a circuit board;
a charge receiving coupler located on the circuit board, comprising a switch assembly comprising a gear transmission shaft, a resilient element, a first driving wheel, a second driving wheel fixed on the first driving wheel, a button gear engaged with the first driving wheel, and a button fixed on the button gear, and the charge receiving coupler comprising an inserting member adjacent to the switch assembly comprising a third body, a first electrode and a second electrode, the first electrode and the second electrode mounted on the third body and electrically connected to the circuit board, the inserting member further defining a receiving groove and the second driving wheel partly received in the receiving groove;
wherein the gear transmission shaft extends through the resilient element, the first driving wheel and the second driving wheel, and the first electrode and the second electrode are partly received in the receiving groove;
a power adapter, comprising a body comprising a first cover, a second cover assembly together and a circuit unit mounted on the second cover, and the circuit unit used to transform alternating current to direct current, the power adapter comprising a plug, wherein the plug comprises a first transmission belt, a rotating switch located on the input end of the circuit unit to control the circuit unit on and off, and a second transmission belt wraps around the rotating switch; and
