Abstract

A charging coil body includes a base and a charging coil mounted on the base. The base has long-side side through-holes penetrating toward long-sides of the rectangular installation area and short-side side through-holes penetrating toward short-sides of the rectangular installation area. Both end portions of a first driving shaft passing through the long-side side through-holes are connected to the first pinions which are meshed with the long racks. Both end portions of a second driving shaft passing through the short-side side through-holes are connected to the second pinions which are meshed with the short racks.

Claims

1. An in-vehicle charger comprising:

a basal plate having a rectangular installation area;

a charging coil body movably disposed above the rectangular installation area of the basal plate;

a long-side side driving body disposed at long-sides side of the rectangular installation area; and

a short-side side driving body disposed at short-sides side of the rectangular installation area,

wherein the long-side side driving body includes;

long racks that extends in a long-side direction of the rectangular installation area;

first pinions adapted to roll with respect to the long racks;

a first driving shaft connected to the first pinions; and

a long-side side motor that generates a driving force to rotate the first pinions, a position of the long-side side motor being fixed with respect to the basal plate;

wherein the short-side side driving body includes;

short racks that extends in a short-side direction of the rectangular installation area;

second pinions adapted to roll with respect to the short racks;

a second driving shaft connected to the second pinions; and

a short-side side motor that generates a driving force to rotate the second pinions, a position of the short-side side motor is fixed with respect to the basal plate;

wherein the charging coil body includes a base and a charging coil mounted to the base; and

wherein the base has long-side side through-holes through which the first driving shaft passes toward the long-sides of the rectangular installation area and short-side side through-holes through which the second driving shaft passes toward the short-sides of the rectangular installation area.

2. The in-vehicle charger according to claim 1, wherein the long-side side through-holes are provided on the side of the charging coil of the base and the short-side side through-holes are provided on the side of the basal plate of the base;

and

wherein the first driving shaft and the second driving shaft are arranged in a direction perpendicular to each other and overlapped so that positions of the first driving shaft and the second driving shaft in a thickness direction of the charging coil body are deviated.

3. The in-vehicle charger according to claim 2, wherein each of the short-side side through-holes has groove shape which is opened to the basal plate.

4. The in-vehicle charger according to claim 3, wherein one of a pair of the short-side side through-holes formed in the groove shape has an opening diameter larger than an opening diameter of the other of the pair of the short-side side through-holes.

5. The in-vehicle charger according to claim 1, wherein the in-vehicle charger includes a long-side side feeding screw connected to a driving part of the long-side side motor, a first nut block rotatably holding the first driving shaft is provided on the side of the long-side side feeding screw of the first pinions and is meshed with the long-side side feeding screw, a driving force of the long-side side motor is transmitted to the first pinions and the first driving shaft, and the first pinions are rotated and rolled on the long racks in accordance with the rotation of the long-side side feeding screw and the long-side side motor.

6. The in-vehicle charger according to claim 1, wherein the in-vehicle charger includes a short-side side feeding screw connected to a driving part of the short-side side motor, a second nut block rotatably holding the second driving shaft is provided on the side of the short-side side feeding screw of the second pinions and is meshed with the short-side side feeding screw, a driving force of the short-side side motor is transmitted to the second pinions and the second driving shaft, and the second pinions are rotated and rolled on the short racks in accordance with the rotation of the short-side side feeding screw and the short-side side motor.

7. The in-vehicle charger according to claim 1, wherein the long racks are disposed on both opposing long-sides of the rectangular installation area, the first pinions are provided on both ends of the first driving shaft, and each of the first pinions is rollably meshed with each of the long racks at the both long-sides.

8. The in-vehicle charger according to claim 1, wherein the short racks are disposed on both opposing short-sides of the rectangular installation area, the second pinions are provided on both ends of the second driving shaft, and each of the second pinions is rollably meshed with each of the short racks at the both short-sides.
