Abstract

The present invention relates to a ceiling mounted charging station for charging the battery of an electric vehicle (210) parking on a parking space (200). The charging station comprises a charging arm (120) for connection with the electric vehicle (210). The first end of the charging arm (120) is mounted to a housing (140) of the charging station. A charging interface (180) for connection with a corresponding charging socket (220) of the electric vehicle (210) is located at a second end of the charging arm (120) opposite to the first end. The charging arm (120) is rotatable with respect to the housing (140) between a stored-position and a use-position. The distance of the second end of the charging arm (120) to the ground (250) of the parking space (200) is smaller in the use-position as in the store-position. The invention furthermore relates to a parking structure comprising a multiplicity of parking spaces (15) for vehicles and at least one charging station (22, 23) mounted to the ceiling of the parking structure. The inventive charging station and the inventive parking structure provide the possibility of an easy charging of electric vehicles, wherein installation costs are low.

between each other, wherein the charging arm (120) is rotatable between the stored-position and the use-position around an axis (320) being essentially parallel to a horizontal axis and wherein the first segment (160) is arranged essentially parallel to the axis (320).

2. The charging station of claim 1, wherein the first segment (160) and the second segment (170) enclose an angle between each other which is essentially rectangular.

3. The charging station according to claim 1, wherein the charging arm (120) is rotatable with respect to the housing (140) around a second axis (330).

4. The charging station according to claim 3, wherein the second axis (330) encloses an angle between 70°

and 110°

with the first axis (320).

5. The charging station according to claim 1, wherein the charging station furthermore comprises at least one of the following:

a) a pulling means (350) which is attached to the charging arm (120);

b) a hooking element (240) for a connection cable;

c) a lamp for illumination of the parking space (200).

6. The charging station of claim 5, wherein the hooking element (240) is arranged at the charging interface (180).

7. The charging station of claim 5, wherein the lamp emits a luminous flux of more than 200 lumen.

8. The charging station of claim 1, wherein the first segment (160) of the charging arm (120) comprises a support and/or an interlock mechanism (161) being adapted to lock the charging arm (120) in the use-position and/or to support the movement of the charging arm from the use-position into the store-position.

9. The charging station of claim 8, wherein the first segment (160) comprises an outer carrier element (162) being attached to the housing (140) and an inner carrier element (163) being attached to the second segment (170), wherein a rotation of the charging arm between the use-position and the store-position is achieved by a rotation of the inner carrier element (163) with respect to the outer carrier element (162), and wherein the support and/or interlock mechanism (161) is adapted to support a rotation of the inner carrier element (163) with respect to the outer carrier element (162) and/or to lock the inner carrier element (163) with respect to the outer carrier element (162) in a position corresponding to the use-position of the charging arm.
