Charging device

Abstract

The present invention provides a charging device that allows for easy storage of the arm supporting the charging cable. [Solution] The charging device A1 charges the battery of an electric mobile device. The charging device A1 includes a support structure 5 having an arm 52 that is rotatable relative to the main body 2 while supporting a charging cable. The arm 52 includes a tip 520 that can move between a first position Y1 in which the charging cable is stretched and a second position Y2 in which the charging cable is retracted by rotation. The support structure 5 has an assist mechanism 54 that applies tension to move the tip 520 to the second position Y2. When an external force is applied to the arm 52 that moves the tip 520 to the first position Y1, a force to generate tension is accumulated at the base 541 of the assist mechanism 54, and when the aforementioned external force is released, the tension is applied to the arm 52 by the release of the force accumulated at the base 541 of the assist mechanism 54.

Claims

1. A charging device for charging the battery of an electric mobile vehicle that moves by driving an electric motor with the power of the battery, A power supply unit that outputs power for charging the aforementioned storage battery, The main body housing the aforementioned power supply unit, A charging plug connected to the aforementioned mobile electric device, which supplies power output by the power supply unit to the mobile electric device, A charging cable that supplies power output from the power supply unit to the charging plug, A support structure having an arm that supports the charging cable and is rotatable relative to the main body, Equipped with, The arm includes a tip portion that is movable between a first position in which the charging cable is extended and a second position in which the charging cable is retracted, by the rotation. The support structure has an assist mechanism that applies tension to move the tip portion to the second position. The assist mechanism includes a base that generates tension, a first link portion connected to the base, and a second link portion rotatably connected to the first link portion. When an external force is applied to the arm that moves the tip to the first position, the angle between the first link and the second link increases, and a force for generating the tension is accumulated at the base. A charging device in which, when the external force is released, the tension is applied to the arm as the angle between the first link portion and the second link portion decreases due to the release of the force accumulated in the base portion.

2. The aforementioned base has a built-in spring, The charging device according to claim 1, wherein the force for generating the tension is accumulated in the spring by the elastic deformation of the spring and released by the restoring force of the elastically deformed spring.

3. The support structure includes a base portion fixed to the main body portion, The arm includes an arm link portion that includes the tip portion and is rotatable relative to the base portion, and a joint portion that is fixed to the base portion and supports one end of the arm link portion as a pivot point. The tip portion moves between the first position and the second position along the circumferential direction about the axis of rotation, The second link portion has a mounting end fixed to either the arm link portion or the base portion. The charging device according to claim 1 or claim 2, wherein the base portion is fixed to the other of the arm link portion or the base portion.

4. The charging device according to claim 1 or claim 2, wherein the assist mechanism includes a stopper that maintains the angle between the first link portion and the second link portion in a state greater than or equal to a predetermined value, and a release portion that releases the maintenance by the stopper.
