## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is based on and claims priority under 35 USC 119 from Japanese Patent Application No. 2014-033132 filed on Feb. 24, 2014, the disclosure of which is incorporated by reference herein.
BACKGROUND
1. Technical Field
The present invention relates to a vehicle USB port applied to a vehicle such as an automobile.
2. Related Art
Japanese Patent Application Laid-Open (JP-A) No. 2006-273127 describes a configuration in which an accessory socket that can be used as a power source extraction port is provided to a center console positioned between a driver's seat and a front passenger seat.
However, in conventional configurations an occupant needs to connect a USB converter to an accessory socket when using a USB device in a vehicle. It is therefore conceivable to provide a USB port to a center console or the like. In such cases, it is preferable to provide a shutter to cover and protect the USB port when not in use; however providing a shutter would increase the number of components.
SUMMARY
In consideration of the above circumstances, an object of the present invention is to provide a vehicle USB port that can protect a USB port without increasing the number of components.
A first aspect of the present invention provides a vehicle USB port including:
a base body attached to a vehicle-body-side member;
a hook main body that is provided with a hinge portion rotatably attached to the base body and a hook portion to anchor an anchored member, and that is rotatable between an in-use position in which the hook portion is usable and a stowed position in which the hook portion is not used;
a hook main body retaining portion that is formed at the base body and that retains the hook main body moved to the stowed position;
a port opening that is formed at the hook main body retaining portion and that is covered by the hook main body moved to the stowed position; and
a USB port that is provided in a position facing the port opening, and to which a USB cable can be coupled through the port opening.
In the vehicle USB port of the first aspect of the present invention, the hook main body provided with the hook portion to anchor an anchored member such as a bag or a shopping bag, is rotatably attached to the base body provided to the vehicle-body-side member by the hinge portion. The hook main body moves between the in-use position in which the hook portion is usable and the stowed position in which the hook portion is not used. When the hook main body moves to the in-use position, therefore, the USB port provided in a position facing the port opening formed at the base body can be coupled to a USB cable through the port opening. When moved to the stowed position, the hook main body is retained by the hook main body retaining portion, and the port opening formed at the base is covered and protected by the hook main body moved to the stowed position. Since a hook main body is normally provided in a vehicle cabin interior in order to hang a bag, a shopping bag, or the like thereon, there is no need to provide a separate shutter in order to protect the USB port, and there is no increase in the number of components.
A second aspect of the present invention provides the vehicle USB port of the first aspect, wherein in the hook main body:
one end of the hook main body is the hinge portion;
the other end of the hook main body is the hook portion; and
a portion of the hook main body between the hinge portion and the hook portion configures a lid portion covering the port opening.
In the vehicle USB port of the second aspect of the present invention, the lid portion covering the port opening is provided to the hook main body between the hinge portion at the one end of the hook main body and the hook portion at the other end of the hook main body. This enables the hinge portion and the hook portion to prevent dust and the like from adhering to the USB port through the port opening. Protection performance of the USB port is thereby improved.
A third aspect if the present invention provides the vehicle USB port of the first aspect or the second aspects, wherein
the hinge portion is attached to one portion of the base body, and the inside of the base includes a frame shaped raised portion forming the hook main body retaining portion.
In the vehicle USB port of the third aspect of the present invention, the hinge portion is attached to one portion of the base body, and the inside of the base includes the frame shaped raised portion forming the hook main body retaining portion. This enables the frame shaped raised portion to prevent dust and the like from adhering to the USB port through the port opening. Protection performance of the USB port is thereby further improved.
A fourth aspect of the present invention provides the vehicle USB port of any one of the first through third aspects, wherein
the USB port is fixed to the base plate attached to the vehicle-body-side member, and a leading end of the USB port faces the port opening by attaching the base body to the vehicle-body-side member.
In the vehicle USB port of the fourth aspect of the present invention, the USB port is fixed to the base plate attached to the vehicle-body-side member, and the leading end of the USB port faces the port opening by attaching the base body to the vehicle-body-side member. Positional alignment of the USB port and the port opening of the base body is thereby facilitated, and fitting operation is improved.
A fifth aspect of the present invention provides the vehicle USB port of any one of the first through fourth aspects, wherein:
the base body is configured as a table that is rotatable coaxially to the hook main body between the stowed position and the in-use position; and
an interference prevention cutout is formed at the table such that the table does not interfere with the hook main body in either the in-use position or the stowed position.
In the vehicle USB port of the fifth aspect of the present invention, the table is rotated coaxially to the hook main body between the stowed position and the in-use position. Since the interference prevention cutout is formed at the table, the table does not interfere with the hook main body in either the in-use position or the stowed position. This enables the hook main body to be moved to the in-use position and the USB port to be used, regardless of whether the table is in the stowed position or the in-use position.
The first aspect of the present invention enables the USB port to be protected without increasing the number of components.
The second aspect of the present invention enables the protection performance of the USB port to be improved.
The third aspect of the present invention enables the protection performance of the USB port to be further improved.
The fourth aspect of the present invention enables the fitting operation to be improved.
The fifth aspect of the present invention enables the USB port to be used, regardless of whether the table is in the stowed position or the in-use position

Second Exemplary Embodiment Operation and Advantageous Effects
As illustrated in FIG. 6, in the present exemplary embodiment, the hook main body 14 is retained in the interference prevention cutout 88 formed at the table 52 of the cup holder 50 when the hook main body 14 has been moved to the stowed position. The lid portion 14C of the hook main body 14 covers the port opening 97 when the hook main body 14 has been moved to the stowed position. The hook main body 14 can thereby prevent water, dust, and the like from adhering to the USB port 40 through the port opening 97, enabling the USB port 40 to be protected. The hook main body 14 is normally provided at an upper portion of the back face 12A of the seatback 12 of the seat 11 in order to hang the bag 15, a shopping bag, or the like thereon. There is accordingly no need to provide a separate shutter in order to protect the USB port 40, so that there is no increase in the number of components. This enables the USB port 40 to be protected without increasing the number of components, similarly to in the first exemplary embodiment
In the present exemplary embodiment, the rotation shafts 71 of the hinge portions 70 of the table 52 of the cup holder 50 are coaxial to the rotation shafts 16 of the hinge portion 14A of the hook main body 14, and the table 52 moves between the stowed position illustrated in FIG. 5 and FIG. 6 and the in-use position illustrated in FIG. 7 to FIG. 9 due to the hinge portions 70. Due to the presence of the interference prevention cutout 88 formed at the table 52, there is no interference between the table 52 and the hook main body 14, regardless of whether the table 52 is in the in-use position or in the stowed position. As a result, the hook main body 14 is rotatable between the in-use position and the stowed position, regardless of whether the table 52 is in the stowed position or in the in-use position. The hook main body 14 is thus movable to the in-use position enabling the USB port 40 to be used, regardless of whether the table 52 is in the stowed position or in the in-use position.
As illustrated in FIG. 8, in the present exemplary embodiment, in a state in which a cell-phone 92 is placed on the table 52, the USB port 40 and the cell-phone 92 can be connected by a USB cable 93. Moreover, as illustrated in FIG. 9, in a state in which a tablet 94 is placed on the table 52 instead of the cell-phone 92, the USB port and the tablet 94 can be connected by a USB cable.
