Description

  The present invention relates to an electric vehicle charging / discharging device for charging / discharging an electric vehicle and a plug-in hybrid car, and more particularly to an electric vehicle charging / discharging device provided on a wall surface with a cable.

An electric vehicle charging / discharging device installed in a house or the like is formed in a small size so that it can be installed in a limited space such as a parking lot, but has a charging connector that connects to the electric vehicle at the tip. The one with a cable is provided with a cable holding portion for winding and holding the cable, a holder for holding the charging connector, and the like, and therefore requires a certain amount of installation space.
For example, in Patent Document 1, a holder is disposed on the side of the housing to reduce the amount of protrusion of the entire device, and in Patent Document 2, the holder is disposed toward the front orthogonal to the wall surface. The casing to which the holder is attached is formed thin so that the protruding amount is minimized.

Japanese Patent Laid-Open No. 2015-212490 JP 2014-82896 A

Since the conventional electric vehicle charging / discharging device is configured so that it can be installed in a limited space, when the holder is arranged on the side of the casing, the holder is close to the wall surface and the charging connector is accommodated / removed. When doing so, the charging connector and the operator's hand holding the charging connector are likely to contact the wall surface, and the charging connector and the hand may be damaged. Moreover, since the holder of the charging connector is located on one side of the housing, it is difficult to operate depending on the position of the charging port of the automobile.
On the other hand, in the configuration of Patent Document 2, it is configured so that the charging connector can be easily operated from any direction by arranging the holder forward, but the charging connector protrudes forward from the wall surface. Residents getting in and out of the car may collide, and the charging connector and holder may be damaged.

  Therefore, in view of such problems, the present invention is an electric vehicle charging device that is less likely to interfere with the wall surface and is easy to operate even when the charging connector is operated even when the cable is installed on the wall surface. It aims at providing a discharge device.

In order to solve the above-mentioned problems, the invention of claim 1 is directed to a cable having a charging connector connected to an electric vehicle for charging and discharging, a holder for holding the charging connector, and a cable suspended and held. An electric vehicle charging / discharging device comprising a cable suspension portion, wherein the holder and the cable suspension portion are provided on a case that is installed on a wall surface and the cable is drawn out, and the case is obliquely forward on the left and right side portions. It has a first taper surface which is a facing surface and is formed bilaterally symmetrical. A holder can be mounted on both first taper surfaces, and a holder is mounted on one of the first taper surfaces. It is characterized by that.
According to this configuration, even when the holder is disposed near the wall surface, the side of the housing to be attached is the first tapered surface inclined obliquely forward, so the holder faces obliquely forward. The held charging connector, particularly the gripping portion thereof, can be separated from the wall surface. Therefore, it is possible to prevent the charging connector or the gripped hand from interfering with the wall surface during the holding / removing operation.
And since a holder can be attached to any of the right-and-left side part of a housing | casing, according to the installation environment of a housing | casing, it can install in the direction where a user is easy to use, and convenience is good. In addition, as compared with the configuration in which the charging connector is held toward the front orthogonal to the wall surface, the amount of forward protrusion can be suppressed, so that a narrow space can be effectively used.

According to a second aspect of the present invention, in the configuration of the first aspect, the first tapered surface is formed over the upper and lower sides of the casing and is formed from the left and right end portions of the front surface of the casing.
According to this configuration, since the first tapered surfaces are formed from the left and right end portions of the front surface of the housing, the left and right end portions of the front surface have an obtuse angle. Can be tempered.

According to a third aspect of the present invention, in the configuration according to the first aspect, the holder is attached to the lower portion of the first tapered surface, and the portion to which the holder of the first tapered surface is attached has a width at least greater than the width of the holder. On the other hand, a second taper surface that is an obliquely upward surface is provided on the front upper portion of the housing, and the forward protrusion of the housing becomes smaller as it moves upward.
According to this configuration, since the protruding amount of the upper part of the front surface of the housing that protrudes obliquely upward is small due to the second taper surface, even if a person getting on and off the car contacts, the impact can be reduced. it can. Moreover, since the holder is installed in the lower part with sufficient width of the 1st taper surface, it is not influenced by the 2nd taper surface but can be attached in the stable state.

According to the present invention, even if the holder is arranged near the wall surface, the side of the housing to be attached is the first tapered surface that is inclined obliquely forward, so the holder faces obliquely forward. The held charging connector, particularly the gripping portion thereof, can be separated from the wall surface. Therefore, it is possible to prevent the charging connector or the gripped hand from interfering with the wall surface during the holding / removing operation.
And since a holder can be attached to any of the right-and-left side part of a housing | casing, according to the installation environment of a housing | casing, it can install in the direction where a user is easy to use, and convenience is good. In addition, as compared with the configuration in which the charging connector is held toward the front orthogonal to the wall surface, the amount of forward protrusion can be suppressed, so that a narrow space can be effectively used.

FIG. 1 is a perspective view, FIG. 2 is a front view, and FIG. The electric vehicle charging / discharging device 1 includes a metal housing 2 that is attached to a wall surface and accommodates a terminal block and a circuit board, and is a cable 3 that is pulled out from the housing 2 and energizes a charging current, A charging connector 4 provided at the tip of the cable 3 for connecting to the electric vehicle, a holder 5 for holding the charging connector 4, a cable suspension 6 for winding and holding the cable 3 and the like are provided.
The electric vehicle charging / discharging device 1 has a function of performing discharging (supplying electric power to the outside of an electric device in a house using the electric vehicle as a power source) in addition to charging. This is an emergency stop button for stopping.

  The housing 2 includes a back surface 2a, a rectangular box body 21 having an upper surface, a lower surface, and left and right side surfaces and an open front surface, and a closing body 22 that closes the front surface of the box body 21. The closing body 22 is hinged to the box body 21 on the left side when viewed from the front, and the snap lock 11 is attached to the right side section so that the closing body 22 can be opened and closed. And the electric vehicle charging / discharging apparatus 1 is attached to a wall surface by the back surface of the box 21 being closely_contact | adhered and fixed to wall surfaces, such as a house.

The closing body 22 has a rectangular base frame portion 22a that matches the front opening of the box body 21 at the back, and is formed so as to close the front surface of the box body 21 without a gap. On the front side of the base frame portion 22a, tapered surfaces are formed on the left and right side portions, and a surface (first tapered surface) 22b facing obliquely forward is formed. The first taper surface 22b is formed so as to extend vertically, and the closing body 22 is formed to be narrowed forward, and has a substantially triangular shape as shown in the sectional view of FIG. Therefore, the front surface 22c of the housing 2 is formed with a narrow width and a band shape.
And the width W 1 of the site | part in which the holder 5 of the 1st taper surface 22b was installed is formed slightly wider than the width W 2 of the holder 5.
The width W1 of the first taper surface of the holder 5 attachment portion may be the same as the width W2 of the holder 5 or may be formed wider.

  Further, a surface (second taper surface) 22d that faces obliquely upward is formed on the upper surface of the front surface 22c, and a substantially triangular inclined surface is formed by being hooked on the first taper surface 22b. The second tapered surface 22d is formed in a region of about one third of the length (height) of the housing 2 and is uniformly formed up to a portion close to the base frame portion 22a. The emergency stop button 1a is disposed on the second tapered surface 22d.

  The cable suspension portion 6 is attached so as to hang down from the lower surface of the housing 2 from which the cable 3 is drawn, and is formed by bending a rod-shaped steel material into a hook shape. The cable 3 drawn out from the lower surface of the housing 2 is wound around the cable suspension 6 as shown in FIG. 1 and the like when not in use, and then the charging connector 4 at the tip is held by the holder 5.

In the holder 5, a holding recess 5 a that accommodates the tip of the charging connector 4 is formed obliquely upward. And this holder 5 is attached to the lower part of one 1st taper surface 22b which is the right side view as shown in FIG.
The holding recess 5a has a locking portion (not shown) for locking the inserted charging connector 4, and is formed so as not to be easily removed. The charging connector 4 can be removed by grasping the grip portion 4a, and the tip of the charging connector 4 is connected to a charging port (not shown) of the electric vehicle.

  FIG. 4 is an explanatory view of attachment of the holder 5 and shows a state in which a part of the closing body 22 is viewed from the back. As shown in FIG. 4, the holder 5 is attached by being screwed and fixed from the inside of the housing 2. Specifically, the closure body 22 is opened, and a screw 15 is inserted from the back side through a through hole 14 drilled at a predetermined position of the first tapered surface 22 b, and is formed on the back surface of the holder 5. It is fixed by screwing into the screw hole 5b.

The through hole 14 for attaching the holder 5 is also formed in the first tapered surface 22b on the opposite side (the right side in FIG. 4) to which the holder 5 is not attached. It is blocked by a closing means such as a closing screw 16 and a nut 17.
Thus, the holder 5 can be moved to the left and right as indicated by the arrow B just by replacing the screws 15 and 16, and can be attached to both the first tapered surfaces 22b and 22b on both the left and right sides. These have shown the state which moved the attachment site | part of the holder 5. FIG.

Thus, since the holder 5 faces diagonally forward, the grip portion 4a of the held charging connector 4 can be separated from the wall surface even when the holder 5 is attached to a portion close to the wall surface. Therefore, it is possible to prevent the charging connector 4 and the gripped hand from interfering with the wall surface during the holding / removing operation. And since the holder 5 can be attached to any of the left and right side portions of the housing 2, it can be installed in a direction that is easy for the user to use according to the installation environment of the housing 2, and is convenient. In addition, since the charging connector 4 that faces diagonally forward can be prevented from projecting forward, even if it is a small installation space, it is difficult to collide when getting on and off the automobile, and the narrow space can be effectively used.
In addition, since the first tapered surfaces 22b are formed from the left and right end portions of the front surface of the housing 2, the left and right end portions of the front surface 22c have an obtuse angle, and even if a person touches the vehicle when getting on or off the vehicle, the impact can be reduced. it can.
Further, since the upper portion of the front surface of the housing 2 protruding is inclined with the second tapered surface 22d formed, the amount of protrusion of the upper portion can be reduced, and the contact of a person getting on and off the automobile can be reduced. Even so, the shock can be reduced. Moreover, since the holder 5 is installed in the lower part with sufficient width | variety of the 1st taper surface 22b, it is not influenced by the 2nd taper surface 22d, but can be attached in the stable state.

  In the above-described embodiment, the first tapered surface 22b is formed on the closing body 22 of the housing 2 and is not formed on the side portion of the box body 21, but on the front surface 22c from the middle of the side portion of the housing 2. Although it is hung, the entire side portion may be the first tapered surface 22b from the vicinity of the back surface of the housing 2 which is formed thinly and is in close contact with the wall surface, or the second tapered surface 22d. The front surface 22c may be extended to the upper end of the housing 2 without the above.
