Summary of the Invention

Problems to be Solved by the Invention

[0004] The charging device disclosed in Patent Document 1 suspends and supports a charging cable with a wire. By pulling out the wire from the winding reel, the spiral coiled portion in the charging cable extends, and by winding up the wire with the winding reel, the coiled portion contracts and the charging cable is stored.

[0005] On the one hand, there are heavy and rigid charging cables for electric vehicles. The charging device described in Patent Document 1 does not assume the use of such charging cables. Therefore, in the charging device described in Patent Document 1, there is a problem that the operability and convenience when winding the charging cable are reduced when such a charging cable is used.

[0006] Therefore, one of the objectives is to provide a charging cable storage device that can improve the operability of the charging operation and the convenience when storing the charging cable.

DETAILED DESCRIPTION OF THE INVENTION

[0010] [Description of Embodiments of the Present Disclosure] (1) The charging cable storage device according to the present disclosure includes a charging cable having a charging connector attached to its tip, a wire provided along the charging cable and having a first end fixed to the charging connector side, a plurality of insertion tools provided at a predetermined interval from the charging cable and having insertion portions through which the wire is inserted, a winding tool that winds the wire from the second end side of the wire, and a cable hanger that hangs and stores the charging cable pulled by the winding tool winding the wire.

[0011] According to the above charging cable storage device, when the wire is wound from the second end side by the winding tool, since a plurality of insertion tools through which the wire is inserted are provided at a predetermined interval in the charging cable, the charging cable can also be pulled toward the winding tool side when the wire is wound by the winding tool. Then, the pulled charging cable can be hung on the cable hanger and stored. Therefore, even when the charging cable is heavy and hard, the operability when handling the charging cable can be improved, and the labor required for storing the charging cable can be reduced. From the above, according to the above charging cable storage device, it is possible to improve the operability of the charging operation and the convenience when storing the charging cable.

[0012] (2) In the above (1), the winding tool may include a rotating body that winds the wire and a driving unit that rotationally drives the rotating body by power. By doing so, the driving unit can rotationally drive the rotating body to wind the wire and pull in and store the charging cable. In this case, since the rotational drive of the rotating body can be performed by power, more labor can be reduced.

[0013] (3) In the above (2), the winding tool may further include a detection unit that detects the winding force of the wire by the rotating body. The driving unit may stop the rotational drive of the rotating body when the winding force detected by the detection unit exceeds a predetermined threshold. By doing so, when the winding force becomes excessive in response to entanglement of the wire or the charging cable during winding of the wire, this can be detected and the rotational drive can be stopped. Therefore, the risk of damage to the winding tool, the wire, or the charging cable during winding in the winding tool can be reduced.

[0014] (4) In the above (2) or (3), the rotating body may be freely supported. By doing so, since the rotating body around which the wire is wound can rotate freely, the charging cable can be pulled out relatively easily when pulling out the charging cable during charging. Therefore, the degree of freedom of the user's operation when pulling out the charging cable can be increased.

[0015] (5) In any one of (2) to (4) above, it may further include a holder that holds the charging connector, a holder detection unit that detects that the charging connector is held by the holder, and an operation unit that receives a driving operation of the winder. When the holder detection unit detects that the charging connector is held by the holder, the operation unit may be capable of receiving a winding instruction for the wire. By doing so, it is possible to surely start winding the wire after the charging connector is held by the holder, and it is possible to reduce the risk of the wire being wound during charging or when the charging cable storage is not expected.

[0016] (6) In any one of (1) to (5) above, the second end of the wire may be fixed to the insertion tool that is located closest to the charging connector among the plurality of insertion tools. By doing so, the wire can be drawn from the charging connector side, and the charging cable can be stored more smoothly.

[0017] (7) In any one of (1) to (6) above, the cable hanger may be disposed on the lower side in the vertical direction than the winding port by the winder. The winder may wind the wire until the plurality of insertion tools are located above the cable hanger, and then release the winding of the wire to hang the charging cable on the cable hanger. By doing so, after winding the wire and pulling the charging cable back to the storage location, the bundled charging cable is guided and lifted by the rotation of the further rotating body, and finally the charging cable bundled on the cable hanger can be hooked. Therefore, it is possible to further improve the efficiency of the work until the charging cable is hooked on the cable hanger.

[0018] (8) In any of the above (1) to (7), a guide portion may be further provided below the cable hanger, inclined from the lower side in the vertical direction toward the tip side of the cable hanger, and guiding the movement of the charging cable so as to cross over the cable hanger. By doing so, the risk of the charging cable caught on the cable hanger falling due to the inclination of the guide portion can be greatly reduced. Therefore, the state of the charging cable being caught on the cable hanger can be more reliably maintained.

[0019] (9) In any of the above (1) to (8), each of the plurality of insertion tools may include a hollow cylindrical tubular portion through which the charging cable can pass inside. When storing the charging cable hung on the cable hanger, it is possible to avoid a large local load being applied to the charging cable. Therefore, the risk of damage to the charging cable during storage can be reduced.

[0020] (10) The charging device according to the present disclosure includes any one of the charging cable storage devices of the above (1) to (9) and a charger used when charging the in-vehicle battery of the electric vehicle to which the charging cable is connected.

[0021] Such a charging device can improve the operability of the charging operation and the convenience during storage of the charging cable.

[0022] [Details of Embodiments of the Present Disclosure] Next, embodiments of the charging cable storage device of the present disclosure will be described with reference to the drawings. In the following drawings, the same or corresponding parts are denoted by the same reference numerals and their descriptions will not be repeated.

[0023] (Embodiment 1) The charging cable storage device in Embodiment 1 of the present disclosure will be described. FIG. 1 is a schematic diagram simply showing the charging device and the charging cable storage device included in the charging device in Embodiment 1 of the present disclosure. FIG. 2 is a schematic diagram showing a state in which the charging cable is bundled, hooked on a cable hanger, and stored. FIG. 3 is a block diagram showing a schematic configuration of a winding device to be described later. Referring to FIGS. 1, 2, and 3, the charging device 10a in Embodiment 1 includes a charging cable storage device 11a and a charger 12a to which a charging cable 13a is connected. The charger 12a is mainly used, for example, when charging an in-vehicle battery of an electric vehicle. However, the charger 12a is a so-called household charger, and for example, chargers for 3 kW (kilowatts) or 6 kW may be mainly used. A charging cable 13a is connected to the charger 12a. The charging cable 13a has a solid cylindrical shape, is relatively heavy, thick, and hard. The charging cable 13a is mainly a 7 m (meter) or 15 m cable, for example, depending on the application. A charging connector 14a called a so-called gun is attached to the tip of the charging cable 13a. The charging connector 14a is connected to an insertion port 16a of a vehicle 15a such as an electric vehicle or a plug-in hybrid vehicle during charging.

[0024] Here, the configuration of the charging cable storage device 11a will be described. The charging cable storage device 11a includes a charging cable 13a, a storage unit 17a for storing the charging cable 13a, a wire 18a which is a wire, a plurality of insertion tools 19a, insertion tool 19b, insertion tool 19c, and a winding tool 20a. In the present embodiment, the total number of the insertion tools 19a is three. However, the number of the insertion tools 19a is not limited to this, and it may be two or four or more. The charging cable 13a extends from the charger 12a. The extending direction of the charging cable 13a is the longitudinal direction of the charging cable 13a. The storage unit 17a includes a cable hanger 21a and a guide portion 22a. The cable hanger 21a is attached so as to protrude from the outer portion of the housing of the charger 12a. The tip of the cable hanger 21a is along the vertically upward direction, and the charging cable 13a bundled and stored in the cable hanger 21a is configured not to easily slip off. The guide portion 22a is inclined such that the tip of the cable hanger 21a protrudes from the lower side to the upper side in the vertical direction. For example, by providing the cable hanger 21a so as to protrude from the back side portion of the housing of the charger 12a, the stored charging cable 13a can be made less visible. By doing so, the overall appearance when the charging cable 13a is stored can be improved. The guide portion 22a is composed of a smooth surface. Note that the first end which is one end of the wire 18a is fixed to the storage unit 17a side, specifically, the center of a rotating body 32a which will be described later.

[0025] In addition, the vertical height of the cable hanger 21a is such that a gap is formed between the charging cable 13a and the ground when the charging cable 13a is stored. That is, the insertion tools 19a, insertion tool 19b, insertion tool 19c which will be described later are attached at intervals in the length direction of the charging cable 13a so that a gap is formed between the charging cable 13a and the ground when stored according to the length of the charging cable 13a.

[0026] Further, the storage unit 17a includes a holder 23a for holding the charging connector 14a. The holder 23a is also attached to the outer portion of the housing of the charger 12a.

[0027] Next, the configuration of the insertion tool 19a (first insertion tool) will be described. Note that the insertion tools 19b (second insertion tool) and 19c (third insertion tool) have the same configuration as the insertion tool 19a, except that the locations where they are attached to the charging cable 13a are different, so their descriptions will be omitted. The insertion tool 19a is arranged on the side closest to the charging connector, and the insertion tool 19c is arranged on the side closest to the charger 12a. The insertion tool 19b is arranged at a position close to the middle between the insertion tool 19a and the insertion tool 19c. That is, in this embodiment, the insertion tools 19a, 19b, and 19c are attached in this order from the side closer to the charging connector 14a.

[0028] FIG. 4 is a schematic perspective view showing an enlarged view of the portion where the insertion tool 19a is attached. Referring also to FIG. 4, the insertion tool 19a includes a cylindrical portion 24a having a hollow cylindrical shape. The charging cable 13a can pass through the inside of the cylindrical portion 24a. That is, the insertion tool 19a has an insertion portion through which the wire 18a as a wire material is inserted. As the material of the insertion tool 19a, for example, ABS (Acrylonitrile Butadiene Styrene) resin, nylon 6, or aluminum is selected. The insertion tool 19a is fixed to the front side and the rear side of the cylindrical portion 24a in the extending direction of the charging cable 13a by using, for example, a binding band or the like. The insertion tool 19a includes a ring portion 25a through which the wire 18a passes. The ring portion 25a is provided so as to protrude to the outer diameter side of the cylindrical portion 24a. The ring portion 25a is provided so as to be rotatable with respect to the cylindrical portion 24a. By doing so, when the direction of the charging cable 13a changes, the angle of the ring portion 25a can be changed to correspond. The second end portion, which is the other end portion of the wire 18a, is connected and fixed to the ring portion 25a. Note that the wire 18a passes through the ring portions 25a of the insertion tools 19b and 19c.

[0029] Regarding the position for fixing the wire 18a, since the fixing position is drawn in when the wire 18a is wound, in order to properly hang the charging cable 13a on the cable hanger 21a, it is necessary to keep the fixing position of the wire 18a at a certain distance from the charging connector 14a. That is, the wire 18a is fixed at a position where the first end of the wire 18a is separated from the charging connector 14a by a predetermined distance. As the fixing position of the wire 18a, for example, in order to prevent the charging cable 13a from contacting the ground, the length is set to be smaller than the distance obtained by adding the distance from the cable hanger 21a to the ground and the distance from the holder 23a to the ground.

[0030] Next, the configuration of the winder 20a will be described. The winder 20a includes a clutch 31a, a rotating body 32a, a motor 33a, a motor drive circuit 34a, a rotation sensor 35a, a control unit 36a, and a storage unit 37a. The clutch 31a can be operated from the operation unit 38a of the charger 12a, and when pulling out the charging cable 13a, the connection part between the gear and the rotating body 32a can be released so that the rotating body 32a can be switched to free rotation. The motor 33a rotates the rotating body 32a and winds the wire 18a around the rotating body 32a. The motor 33a functions as a drive unit that rotationally drives the rotating body 32a by electric power. The motor drive circuit 34a drives and controls the motor 33a, and the power supply of the motor drive circuit 34a is supplied from the power supply circuit 40a of the charger 12a. The rotation sensor 35a measures the rotation speed of the rotating body 32a to grasp the zero-point information on how much the wire 18a should be wound and how much the wire 18a has been pulled out. The zero-point information is stored in the storage unit 37a via the control unit 36a. Also, the rotation sensor 35a detects the torque of the rotating body 32a, and when it detects that a torque equal to or greater than a certain value is applied so as not to damage fingers or the like due to the wire 18a being entangled, it has a function of stopping the winding of the wire 18a via the control unit 36a. That is, the rotation sensor 35a functions as a detection unit that detects the winding force of the wire 18a by the rotating body 32a. The control unit 36a is supplied with power from the power supply circuit 40a of the charger 12a, and controls the motor drive circuit 34a based on the information from the operation unit 38a, the rotation sensor 35a, and the storage unit 37a.

[0031] The holder 23a that holds the charging connector 14a may have a holder detection unit 39a that detects that the charging connector 14a is held by the holder 23a. When the holder detection unit 39a detects that the charging connector 14a is held by the holder 23a, the operation unit 38a can accept a winding instruction for the winder 20a, and simultaneously with or automatically when the charging connector 14a is held by the holder 23a, or by operating the winding instruction button of the operation unit 38a, a winding instruction is given to the control unit 36a to drive the motor 33a to wind up the wire 18a, and the charging cable 13a may be stored.

[0032] Next, the case of charging the vehicle 15a by the charging device 10a will be described. When charging, first, the charging cable 13a is extended. When extending the charging cable 13a, the charging connector 14a is removed from the holder 23a and pulled. Then, the charging cable 13a comes off the cable hanger 21a and is gradually extended. In this case, since the rotating body 32a is free, when releasing the winding state of the wire 18a wound around the rotating body 32a, no force other than the rotational resistance is applied, and the charging cable 13a can be smoothly extended.

[0033] After charging is completed, the following steps are taken. After the charging connector 14a is held by the holder 23a, the charging cable 13a is stored. FIG. 5 is a schematic diagram showing a state in which the charging connector 14a is held by the holder 23a. In this case, the charging cable 13a and the wire 18a are extended, and a part of them is in a state of crawling on the ground.

[0034] Thereafter, the rotating body 32a is rotated by the winding tool 20a. As a result, the wire 18a is wound around the rotating body 32a. At this time, the insertion tool 19a, to which the second end of the wire 18a is fixed, approaches the storage section 17a. As the rotating body 32a is further rotated, the wire 18a is wound around the rotating body 32a. Then, the insertion tool 19a, the insertion tool 19b, and the insertion tool 19c, in which the wire 18a is threaded through the ring section 25a, are gathered together in one place. FIGS. 6 and 7 are schematic diagrams showing the state in which the insertion tool 19a, the insertion tool 19b, and the insertion tool 19c are gathered together in one place. FIG. 6 shows the charging cable storage device 11a as viewed from the front, and FIG. 7 shows the charging cable storage device 11a as viewed from the side. Referring to Figures 6 and 7 together, for charging cable 13a, insertion devices 19a, 19b, and 19c come into contact with and interfere with each other due to the winding of wire 18a, and therefore are bundled around the positions where insertion devices 19a, 19b, and 19c are attached.

[0035] Thereafter, when the rotating body 32a is further rotated, the insertion tools 19a, 19b, and 19c are further drawn toward the retraction opening 29a. The charging cable 13a is then lifted along the guide portion 22a. FIGS. 8 and 9 are schematic diagrams showing the state in which the charging cable 13a is lifted along the guide portion 22a. FIG. 8 shows the charging cable storage device 11a as viewed from the front, and FIG. 9 shows the charging cable storage device 11a as viewed from the side. Referring to FIGS. 8 and 9 together, the portion where the insertion tools 19a, 19b, and 19c are concentrated is lifted along the guide portion 22a, which is inclined so that the tip of the cable hook 21a protrudes. Then, the charging cable 13a finally reaches the position where the cable hook 21a is provided, and the bundled charging cable 13a is hooked onto the cable hook 21a at the positions where the insertion tool 19a, the insertion tool 19b, and the insertion tool 19c are provided, respectively, resulting in the hooked state as shown in Fig. 2. Fig. 10 is a schematic diagram showing the state in which the charging cable 13a is bundled, hooked onto the cable hook 21a, and stored, as seen from the side of the charging cable storage device 11a. In this manner, the charging cable 13a is stored.

[0036] According to this charging cable storage device 11a, when the winding tool 20a winds the wire 18a from the second end side, the plurality of insertion tools 19a, 19b, and 19c through which the wire 18a is inserted are provided at predetermined intervals on the charging cable 13a. This allows the charging cable 13a to be pulled toward the winding tool 20a when the winding tool 20a winds the wire 18a. The pulled charging cable 13a can then be hung on the cable hook 21a and stored. This improves the operability of handling the charging cable 13a even when the charging cable 13a is heavy and stiff, and reduces the effort required to store the charging cable 13a. As described above, the charging cable storage device 11a improves the operability of the charging operation and the convenience of storing the charging cable 13a.

[0037] In this embodiment, the winding device 20a includes a rotating body 32a that winds up the wire 18a and a motor 33a as a drive unit that uses electricity to rotate the rotating body 32a. Therefore, the drive unit rotates the rotating body 32a to wind up the wire 18a and retract the charging cable 13a for storage. In this case, because the rotating body 32a can be rotated using electricity, the labor required can be further reduced.

[0038] In this embodiment, the winding device 20a includes a detection unit that detects the winding force of the rotator 32a on the wire 18a. The motor 33a stops the rotational drive of the rotator 32a when the winding force detected by the detection unit exceeds a predetermined threshold. Therefore, if the winding force becomes excessive when winding the wire 18a due to entanglement of the wire 18a or the charging cable 13a, this can be detected and the rotational drive can be stopped. This reduces the risk of damage to the winding device 20a, the wire 18a, or the charging cable 13a when winding the wire 18a.

[0039] In this embodiment, the rotating body 32a is supported freely. Therefore, the rotating body 32a around which the wire 18a is wound can rotate freely, which allows the charging cable 13a to be pulled out relatively easily during charging. This increases the user's freedom of operation when pulling out the charging cable 13a.

[0040] In this embodiment, it includes a holder 23a that holds the charging connector 14a, a holder detection unit 39a that detects that the charging connector 14a is held by the holder 23a, and an operation unit 38a that receives a drive operation of the winder 20a. When the holder detection unit 39a detects that the charging connector 14a is held by the holder 23a, the operation unit 38a can receive a winding instruction for the wire 18a. Therefore, the winding of the wire 18a can be surely started after the charging connector 14a is held by the holder 23a, and the possibility that the wire 18a is wound during charging or when the charging cable 13a is not expected to be stored can be reduced.

[0041] In this embodiment, the second end of the wire 18a is fixed to the inserter 19a that is located closest to the charging connector 14a among the plurality of inserters 19a, 19b, and 19c. Therefore, the wire 18a can be pulled from the charging connector 14a side, and the charging cable 13a can be stored more smoothly.

[0042] In this embodiment, the cable hanger 21a is arranged on the lower side in the vertical direction than the winding port 29a by the winder 20a. The winder 20a winds the wire 18a until the plurality of inserters 19a, 19b, and 19c are located above the cable hanger 21a, and then releases the winding of the wire 18a to hang the charging cable 13a on the cable hanger 21a. Therefore, after the wire 18a is wound and the charging cable 13a is pulled back to the storage location, the bundled charging cable 13a is guided and lifted by the further rotation of the rotating body 32a, and finally the charging cable 13a bundled on the cable hanger 21a can be hooked. Therefore, further efficiency improvement of the operation until the charging cable 13a is hooked on the cable hanger 21a can be achieved.

[0043] In the present embodiment, a guide portion 22a is provided below the cable hanger 21a, inclines from the lower side in the vertical direction toward the tip side of the cable hanger 21a, and guides the movement of the charging cable 13a so as to cross over the cable hanger 21a. Therefore, the inclination of the guide portion 22a can greatly reduce the risk of the charging cable 13a caught on the cable hanger 21a from falling. Thus, the state in which the charging cable 13a is caught on the cable hanger 21a can be more reliably maintained.

[0044] In the present embodiment, each of the plurality of insertion members 19a, 19b, and 19c includes a hollow cylindrical tubular portion 24a through which the charging cable 13a can pass inside. Therefore, when the charging cable 13a hung on the cable hanger 21a is stored, it is possible to avoid locally applying a large load to the charging cable 13a. Thus, the risk of damage to the charging cable 13a during storage can be reduced.

[0045] The charging device 10a according to the present disclosure includes the above-described charging cable storage device 11a and a charger 12a that is used when charging the in-vehicle battery of an electric vehicle and to which the charging cable 13a is connected.

[0046] Such a charging device 10a can improve the operability of the charging operation and the convenience during storage of the charging cable 13a.

[0047] (Other embodiments) In the above embodiment, a wire is used as the wire material. However, the present invention is not limited to this, and other members having a certain degree of rigidity may be used as the wire material.

[0048] In the above-described embodiment, as shown in FIG. 11, a handle 28a may be provided on the rotating body 32a, allowing the rotating body 32a to be manually rotated. FIG. 11 is a schematic diagram of a charging cable storage device 11b in which a handle 28a is provided on the rotating body 32a. Referring to FIG. 11, the rotating body 32a can be rotated by rotating the handle 28a. In this way, the winding of the wire by the winding tool can be performed manually. This simplifies the configuration. Furthermore, the wire can be wound without requiring electric power.

[0049] In the above-described embodiment, the charging device may be, for example, a charging / discharging device having a charging / discharging function compatible with V2H (Vehicle to Home).

[0050] It should be understood that the embodiments disclosed herein are illustrative in all respects and are not limiting in any respect. The scope of the present invention is defined not by the above description but by the claims, and it is intended to include all modifications within the meaning and scope of the claims.
