ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a supporting device for a power supply paddle used for feeding electricity from a power source to a power receiving device using electromagnetic induction.
2. Description of the Related Art
Concerning a charger for charging a battery, which is incorporated into an automobile, with electricity, there is provided a charger having a power supply paddle for feeding electricity from a power source to a power receiving device using electromagnetic induction.
FIG. 11
is a view showing an example of the charger. The power supply paddle
1
is attached to an end of the feeder cable
3
extending from the feeder stand
2
installed on the ground. The electric automobile
5
into which the battery
4
is incorporated has a charging port
6
which is a power receiving device. As shown by chain lines in the drawing, the power supply paddle
1
is inserted into the insertion hole of the charging port
6
. When the power supply paddle
1
is inserted into the insertion hole of the charging port
6
in this way, the battery
4
is electrically charged by electromagnetic induction between the coil provided on the power supply paddle
1
side and the coil provided on the charging port
6
side.
While the power supply paddle
1
is not being used, the power supply paddle
1
is inserted into and held by the supporting section
7
provided in the feeder stand
2
. The manufacturing cost of the entire charger may be high according to the structure of the supporting section
7
.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a supporting device, for a power supply paddle, the manufacturing cost of which is advantageously low.
In order to accomplish the object, the present invention provides a supporting device for a power supply paddle for feeding electricity from a power source to a power receiving device, using electromagnetic induction, comprising: a first accommodation space forming body for forming an accommodation space to accommodate the power supply paddle capable of being taken in and out; and a second accommodation space forming body for forming an accommodation space to accommodate the power supply paddle when combined with the first accommodation space forming body in such a manner that the second accommodation space forming body is opposed to the first accommodation space forming body, wherein the profile and size of the first accommodation space forming body is the same as those of the second accommodation space forming body, engaging protrusions and engaging recesses, the numbers of which are the same, are provided on one face of the first accommodation space forming body and also on one face of the second accommodation space forming body, and the engaging protrusions of one of the first accommodation space forming body and the second accommodation space forming body are engaged with the engaging recesses of the other accommodation space forming body so that the accommodation space is formed between the first accommodation space forming body and the second accommodation space forming body.
When the engaging protrusions of one of the first and the second accommodation space forming body are engaged with the engaging recesses of the other of the first and the second accommodation space forming body, the first and the second accommodation space forming body are opposed to each other so that they can form the accommodation space. The structure in which a pair of accommodation space forming bodies of the same profile and size are combined with each other is effective for suppressing an increase in the manufacturing cost of the supporting device.
The present invention may be more fully understood from the description of the preferred embodiments of the invention set forth below together with the accompanying drawings.
