Summary of the Invention

Problems to be Solved by the Invention

[0004] When such a holding portion is put away after using the power supply cable, it is necessary to manually wind the power supply cable around it. However, since the power supply cable is often used in a state of being laid on the ground and is thus dirty, the hands will get dirty when manually holding the power supply cable to put it away.

[0005] In view of this situation, the main problem of the present invention is to provide a cable winder for vehicle power supply that can put away the power supply cable without getting the hands dirty.

Means for Solving the Problems

[0006] The first characteristic configuration of the present invention includes a drum portion capable of rotational operation, and a string-like body whose proximal end portion is connected to the drum portion, where the distal end portion of the string-like body is configured to be connectable to a power supply cable for supplying power to a vehicle to be powered, The drum section is equipped with a winding and storage section that allows the string-like body to be wound around and stored, and subsequently the power supply cable to be wound around and stored, by rotating the drum section while the tip portion of the string-like body is connected to the power supply cable.

[0007] With this configuration, the cord-like material and power supply cable can be wound and stored in the winding compartment of the drum by rotating the drum, making it possible to put away the power supply cable without getting your hands dirty. In addition, when winding by rotating the drum, the cord-like material, which has less winding resistance than the cable, is wound first, allowing the winding process to start smoothly. Furthermore, by connecting the power supply cable to the drum via the cord-like material, it is not necessary to connect the power supply cable directly to the drum, and the power supply cable can be used without being restricted by the position of the drum, thus improving the usability of the power supply cable.

[0008] A second characteristic configuration of the present invention is that the cord-like body, which is wound onto the winding storage section by the rotational operation of the drum section, is provided with a cord-like body guide section that can guide the cord-like body, which is located at an intermediate position in the direction of the rotation axis of the winding storage section, The winding storage section is characterized in that, by rotating the drum section with the tip portion of the string-like body connected to the middle portion of the power supply cable, the string-like body is wound around and stored in the string-like body storage section, and then the power supply cable is wound around and stored in such a manner that the tip portion and the base portion of the power supply cable, separated by the middle portion, are distributed to both outer sides in the direction of the rotation axis of the string-like body storage section.

[0009] According to this configuration, the string-like body is wound around and housed in the string-like body housing section at the intermediate part in the direction of the rotation axis, and then the power supply cable is wound around and housed with its tip and base ends distributed to both outer sides in the direction of the rotation axis of the string-like body housing section. As a result, the string-like body and the tip and base ends of the power supply cable are wound around in a way that makes them less likely to become entangled. Furthermore, by connecting a string-like body to the middle of the power supply cable in the longitudinal direction, it is possible to prevent both ends of the power supply cable from being wound onto the drum. For example, the base end of the power supply cable can be connected to an outlet, and the tip of the power supply cable can be held in a holder while the power supply cable is wound around and stored in the cable storage area. Furthermore, although the amount of rotational operation of the drum increases due to winding the string-like material into the winding storage section, by connecting the string-like material to the middle of the power supply cable, both the tip and base ends of the power supply cable can be wound onto the winding drum and stored simultaneously, thereby reducing the amount of rotational operation of the drum required to store the power supply cable. Therefore, even while employing a string-like material, it is possible to suppress the overall increase in the amount of rotational movement of the drum section.

[0010] A third characteristic feature of the present invention is that the winding storage section is provided with hooking sections that hook the intermediate portion of the power supply cable, which is wound up by the rotation operation of the drum section while the tip portion of the string-like body is connected to the intermediate portion of the power supply cable, at multiple points separated in the direction of the rotation axis.

[0011] With this configuration, when winding the string-like body and the power supply cable, the middle section of the power supply cable catches on the hook, and moreover, the middle section of the power supply cable catches at multiple points separated in the direction of the rotation axis. This distributes the load acting on the power supply cable, and also reduces the degree of bending or curvature of the middle section of the power supply cable to which the tip of the string-like body is connected, thereby reducing the burden on the power supply cable.

[0012] A fourth characteristic configuration of the present invention is that the winding storage section is provided with a cable storage section that, when the tip portion of the string-like body is connected to an intermediate point of the power supply cable, rotates the drum section to wind and store the tip portion and the base portion of the power supply cable, with the intermediate point as the boundary. The drum portion is provided with partition walls on both outer sides in the rotational axis direction of the cable housing portion, which protrude radially outward from the winding surface of the winding housing portion and form a partitioned cable housing space, and the central side of the partition wall portion in the rotational axis direction is a cable guide surface that is inclined so that the radially inward side is closer to the center in the rotational axis direction.

[0013] With this configuration, although the amount of rotation of the drum increases due to winding the string-like material into the winding storage section, by connecting the string-like material to the middle of the power supply cable, the tip and base ends of the power supply cable can be wound onto the winding drum and stored simultaneously, thereby reducing the amount of rotation of the drum required to store the power supply cable. Furthermore, when winding the tip and base ends of the power supply cable into the cable storage section, the cable guide surface guides the power supply cable into the cable storage section, so that the tip and base ends of the power supply cable can be properly stored in the cable storage section.

[0014] A fifth characteristic configuration of the present invention is a power supply pole comprising a vehicle power supply cable winding machine and a pole section that can be installed upright on the ground, The pole portion has an outlet mounting area on which a pole outlet can be installed, and a winding machine mounting area on which the vehicle power supply cable winding machine can be installed.

[0015] According to this configuration, the power supply pole can be easily installed by erecting the pole in the ground, attaching a pole outlet to the outlet mounting area on the pole, and attaching a vehicle power supply cable winder to the winding machine mounting area on the pole.

[0016] A sixth feature of the present invention is that the power supply cable is provided with an excess length winding and storage section that can wind and store any excess length that is not needed when connecting to the vehicle. The pole portion is characterized by having an excess length portion winding storage area to which the excess length portion winding storage section can be attached.

[0017] When the power supply cable is longer than necessary compared to the distance between the vehicle to be powered and the power supply pole, the amount of winding around the winding storage part of the power supply cable increases, and the amount of rotational operation during the winding and unwinding operations increases. However, according to this configuration, unnecessary excess length portions of the power supply cable can be wound around and stored in the excess length winding storage part, so that the amount of rotational operation during the winding and unwinding operations can be reduced, and the workability can be improved.

Modes for Carrying Out the Invention

[0019] Embodiments of the vehicle power supply cable winder and the power supply pole according to the present invention will be described based on the drawings. As shown in Figure 1, the power supply pole 1 includes a vehicle power supply cable winder 3 capable of winding up the power supply cable 2 that supplies power to the vehicle to be powered, an excess length winding and storage section 4 capable of winding and storing the excess length 2A of the power supply cable 2 that is not needed when connected to the vehicle, and a pole section 5 that can be installed upright on the ground. In this embodiment, the vehicle to be powered is an electric vehicle.

[0020] In addition to the vehicle power supply cable winding machine 3 and the excess length winding storage section 4, the pole section 5 is configured to accommodate a pole outlet 11 to which a plug can be connected, a connector holder 12 to which a charging connector 8 can be connected, and a box holder 13 to which a control box 9 can be held.

[0021] The power supply cable 2 comprises a plug (not shown) at the base end of the power supply cable 2, a charging connector 8 at the tip of the power supply cable 2, and a control box 9 located near the base end of the power supply cable 2. When connecting the power supply cable 2 to the vehicle, if the power supply cable 2 is too long, as shown in Figure 4, an unnecessary excess length portion 2A is set in the power supply cable 2 near the control box 9 on the end side of the cable. The excess length portion winding and storage section 4 is configured to wind and store this excess length portion 2A, as shown in Figures 1 and 5. Furthermore, as shown in Figure 1, the vehicle power supply cable winding machine 3 is configured to wind and store the usable portion 2B, which is the end side of the excess length portion 2A.

[0022] The following explanation will describe the power supply pole 1 and the vehicle power supply cable winding machine 3. As shown in Figure 1, the direction along which the pole section 5 follows is defined as the vertical direction Z, and is described as the upper side Z1 and the lower side Z2. The direction in which the pole section 5 and the pole outlet 11 are aligned when viewed in the vertical direction is defined as the front-rear direction X, and the side of the pole section 5 where the pole outlet 11 is located is defined as the front side X1. The direction perpendicular to the front-rear direction X when viewed in the vertical direction is defined as the width direction Y, and one side of the width direction Y is defined as the first width direction Y1, and the opposite side as the second width direction Y2.

[0023] To describe the pole section 5, as shown in Figure 1, the pole section 5 is provided with an outlet mounting area 15 on which a pole outlet 11 can be attached, and the pole section 5 is configured in a rectangular tube shape so that a power line (not shown) connected to the pole outlet 11 can be routed inside. Furthermore, the pole section 5 is provided with a connector holder mounting area 16 on which a connector holder 12 for holding the charging connector 8 can be attached, and a box holder mounting area 17 on which a box holder 13 for holding the control box 9 can be attached. In addition, the pole section 5 is provided with a winding machine mounting area 18 on which a vehicle power supply cable winding machine 3 can be attached, and an excess length winding storage area 19 on which an excess length winding storage area 4 can be attached.

[0024] The outlet mounting area 15 is located on the front of the upper end of the pole section 5. The pole outlet 11 is attached to the front side X1 of the upper end of the pole section 5 by mounting it to the outlet mounting area 15 with screws or other mounting means. The box holder mounting area 17 is located below Z2 on the front of the pole section 5, below the outlet mounting area 15. The box holder 13 is attached to the front X1 of the upper and lower middle section of the pole section 5 by attaching it to the box holder mounting area 17 of the pole section 5 with screws or other mounting means. The excess length winding storage area 19 is located below Z2 from the box holder mounting area 17 on the front of the pole section 5. The excess length winding storage area 4 is attached to the excess length winding storage area 19 of the pole section 5 using mounting means such as screws, thereby being attached to the front side X1 of the pole section 5 below the vertical center Z2. The winding machine mounting area 18 is located above Z1 on the side of the pole section 5, above the excess length winding storage area 19. The vehicle power supply cable winding machine 3 is attached to the first side Y1 in the width direction of the upper and lower intermediate part of the pole section 5 by attaching it to the winding machine mounting area 18 of the pole section 5 with mounting means such as screws. The connector holder mounting area 16 is located on the side of the pole portion 5, above the winding machine mounting area 18, in a position Z1. The connector holder 12 is attached to the first side Y1 in the width direction of the upper end of the pole portion 5 by attaching it to the connector holder mounting area 16 of the pole portion 5 with mounting means such as screws. Furthermore, the vehicle power supply cable winding machine 3 and the excess length winding storage section 4 may be attached to the pole section 5 in a detachable manner by engaging them with engaging parts such as hooks provided in the winding machine mounting area 18 and the excess length winding storage section mounting area 19, for example.

[0025] Then, corresponding to the arrangement of the plug, control box 9, and excess length portion 2A from the base end of the power supply cable 2, the pole portion 5 is equipped with an outlet mounting area 15, a box holder mounting area 17, and an excess length portion winding storage area 19, arranged in that order from the top Z1. Also, corresponding to the arrangement of the charging connector 8, usable portion 2B, and excess length portion 2A from the tip end of the power supply cable 2, the pole portion 5 is equipped with a connector holder mounting area 16, a winding machine mounting area 18, and an excess length portion winding storage area 19, arranged in that order from the top Z1.

[0026] The vehicle power supply cable winding machine 3 is mounted in the winding machine mounting area 18 in a position where the rotation axis direction P is in the width direction Y. The excess length winding storage section 4 is mounted in the excess length winding storage section mounting area 19 in a position where the axis direction of the winding shaft that winds the excess length 2A is in the width direction Y. The connector holder 12, mounted in the connector holder mounting area 16, is positioned so that the charging connector 8 of the power supply cable 2 is connected from the first side Y1 in the width direction, and the power supply cable 2 extends from the charging connector 8 connected to the connector holder 12 in the first side Y1 in the width direction and diagonally downward Z2. Incidentally, the connector holder 12 mounted in the connector holder mounting area 16 is mounted so that it overlaps with the vehicle power supply cable winding machine 3 mounted in the winding machine mounting area 18 when viewed from above.

[0027] Next, we will describe the vehicle power supply cable winding machine 3. As shown in Figures 2 and 3, the vehicle power supply cable winder 3 comprises a rotatable drum section 21, a string-like body 22 whose base end is connected to the drum section 21, and an operating handle 25 for rotating the drum section 21. The tip portion 22A of the string-like body 22 is configured to be connectable to the power supply cable 2, as shown in Figure 3. The operating handle 25 may be configured to bend at its base end, allowing it to be folded by bending it from the upright position shown in Figure 2, etc. (a position aligned with the rotation axis P of the drum section 21).

[0028] In this embodiment, as shown in Figures 5 and 6, the tip portion 22A of the string-like body 22 is connected to an intermediate point 23 located in the middle of the longitudinal direction of the power supply cable 2. To elaborate, the intermediate point 23 is set at or near the center of the longitudinal direction of the usable portion 2B of the power supply cable 2 (the portion from the excess length portion 2A that is wound around the excess length portion winding storage portion 4 to the charging connector 8), and the tip portion 22A of the string-like body 22 is connected to the intermediate point 23 of the usable portion 2B of the power supply cable 2. The string-like body 22 is formed using a flexible material such as metal or synthetic resin, and in this embodiment, a wire is used as the string-like body 22.

[0029] When connecting the tip portion 22A of the string-like body 22 to the intermediate portion 23 of the power supply cable 2, a cable protector 24 is used to protect the connection point, as shown in Figure 3. The cable protector 24 is attached to the intermediate portion 23 of the power supply cable 2 by fitting it over and covering the intermediate portion 23, and the string-like body 22 is connected to the power supply cable 2 by wrapping and tying it over the cable protector 24. Furthermore, the cable protector 24 is made of a C-shaped tube made of synthetic resin or the like, and is detachably attached to the intermediate section 23 of the power supply cable 2, and is designed to be less prone to deformation than the intermediate section 23 of the power supply cable 2. In addition, when the power supply cable 2 is suspended by the string-like body 22, the cable protector 24 is formed so that the portion located at the lower side Z2 of the intermediate section 23 is wider than the portion located at the upper side Z1 of the intermediate section 23. The intermediate section 23 of the power supply cable 2 is protected by such a cable protector 24, which prevents the bending radius from becoming smaller than a predetermined radius.

[0030] As shown in Figures 2 and 3, the drum section 21 is equipped with a winding storage section 26 that can wind and store the string-like body 22 by rotating the drum section 21 with the tip portion 22A of the string-like body 22 connected to the power supply cable 2, and then wind and store the power supply cable 2.

[0031] As shown in Figures 2 and 3, the winding storage section 26 is equipped with a string-like body storage section 27 for winding and storing the string-like body 22, and a cable storage section 28 for winding and storing the power supply cable 2. The string-like body housing section 27 is configured to house the string-like body 22 by rotating the drum section 21 while the tip portion 22A of the string-like body 22 is connected to the intermediate portion 23 of the power supply cable 2. Furthermore, the cable housing section 28 is configured to house the power supply cable 2 by rotating the drum section 21 with the tip portion 22A of the string-like body 22 connected to the intermediate portion 23 of the power supply cable 2, thereby winding the string-like body 22 around the string-like body housing section 27. Subsequently, the tip portion and base portion of the power supply cable 2, separated by the intermediate portion 23, are distributed to both outer sides P2 (first side Y1 and second side Y2 in the width direction) of the rotation axis direction P (width direction Y) of the string-like body housing section 27.

[0032] In this embodiment, the string-like body housing portion 27 is located in the middle of the rotation axis direction P in the winding housing portion 26, as shown in Figures 2 and 3. The cable housing portion 28 includes cable housing portions located on both outer sides P2 and radially outward of the string-like body housing portion 27 in the rotation axis direction P in the winding housing portion 26. In the cable housing portion 28, the base end portion of the power supply cable 2 is wound and housed in the cable housing portion located on the second side Y2 in the width direction (the side where the pole portion 5 is located), and the tip portion of the power supply cable 2 is wound and housed in the cable housing portion located on the first side Y1 in the width direction (the side opposite to where the pole portion 5 is located). Furthermore, radially outward from the string-like body guide portion 33, which will be described later, the movement of the power supply cable 2 toward the center side P1 in the rotation axis direction P by the string-like body guide portion 33 is no longer restricted, so the power supply cable 2 can be wound over the entire rotation axis direction P of the winding housing portion 26. Therefore, the cable housing section 28 also includes a cable housing section on the radially outward side of the string-like guide section 33 for winding and housing the power supply cable 2.

[0033] As shown in Figure 3, the drum section 21 is provided with partition wall sections 30 that protrude radially outward from the winding surface 26F of the winding section 26 on both outward sides P2 in the rotation axis direction P of the cable housing section 28, thereby partitioning the cable housing space. The central side P1 surface of the partition wall section 30 is an inclined cable guide surface 31, which becomes more inclined towards the central side P1 in the rotation axis direction P as it moves radially inward. In this embodiment, the cable guide surface 31 has the same diameter as the winding surface 26F at the central side P1 in the rotation axis direction P, and the same diameter as the radially outward end of the partition wall section 30 at the outward side P2 in the rotation axis direction P, so that the entire central side P1 surface of the partition wall section 30 is an inclined cable guide surface 31. Alternatively, only a portion of the radial direction of the central side P1 surface of the partition wall section 30 may be an inclined cable guide surface 31.

[0034] As shown in Figures 2 and 3, the outer sides P2 of the string-like body housing section 27 in the direction of the rotation axis P are provided with string-like body guide sections 33 that can guide the string-like body 22, which is wound around the winding housing section 26 by the rotational operation of the drum section 21, to the string-like body housing section 27. The string-like body guide section 33 is composed of a plurality of protruding members 34 arranged along the circumferential direction. The plurality of protruding members 34 are provided so as to protrude radially outward from the winding surface 26F of the winding housing section 26, and are provided so as to be spaced apart from each other and arranged intermittently along the circumferential direction. The string-like guide section 33 is provided between the cable housing portion located on the first widthwise side Y1 of the cable housing portion 28 and the string-like housing portion 27, and between the cable housing portion located on the second widthwise side Y2 of the cable housing portion 28 and the string-like housing portion 27. The string-like housing portion 27 is separated from the two cable housing portions located on both outer sides P2 by the string-like guide section 33.

[0035] The string guide section 33 is provided on both outer sides P2 in the rotation axis direction P of the string housing section 27, and the surfaces of each of the multiple protruding members 34 facing the center side P1 in the rotation axis direction P are formed in an inclined position such that the radially inward side is closer to the center side P1 in the rotation axis direction P. Therefore, the string guide section 33 is configured to guide the string 22 into the string housing section 27 when the string 22 is wound around the string housing section 27 by the rotation operation of the drum section 21, and to restrict the string 22 wound around the string housing section 27 from detaching from the string housing section 27 to the cable housing section 28.

[0036] Furthermore, the multiple protruding members 34 that constitute the string-like guide section 33 are arranged in a circumferential direction, and as shown by the dashed lines in Figure 3, they are spaced apart so that the intermediate section 23 of the power supply cable 2 can fit between them, and are configured so that the intermediate section 23 of the power supply cable 2 that fits between the circumferentially arranged protruding members 34 can be caught. In addition, the protruding members 34 are arranged in pairs along the rotation axis direction P, and are configured so that the intermediate section 23 of the power supply cable 2, which is wound up by the rotation operation of the drum section 21 with the tip portion 22A of the string-like body 22 connected to the intermediate section 23 of the power supply cable 2, can be caught at two points separated in the rotation axis direction P. In other words, the string-like guide section 33 corresponds to a hooking section that catches the intermediate section 23 of the power supply cable 2 at multiple points separated in the rotation axis direction P.

[0037] Next, the method of using the power supply pole 1 equipped with a vehicle power supply cable winding machine 3 will be described. When using the power supply pole 1 for the first time, an initial setup is performed by connecting the tip portion 22A of the string-like body 22 of the vehicle power supply cable winding machine 3 to the power supply cable 2. In the initial setup, first, as shown in Figure 4, the power supply cable 2 is set on the power supply pole 1, and the excess length portion 2A of the power supply cable 2 is wound around the excess length portion winding storage section 4 so that only the usable portion 2B of the power supply cable 2 is unwound. Next, as shown in Figure 5, the tip portion 22A of the string-like body 22 of the vehicle power supply cable winding machine 3 is connected to an intermediate point 23 of the usable portion 2B of the power supply cable 2 (approximately half the usable portion 2B in this embodiment).

[0038] After initial setup is complete and power is supplied to the vehicle to be powered using the power supply pole 1, when winding up the power supply cable 2 with the vehicle power supply cable winder 3, as shown in Figure 5, the charging connector 8 is held in the connector holder 12, and the tip portion 22A of the string-like body 22 is connected to the middle portion 23 of the power supply cable 2. By rotating the drum portion 21 in this state, the string-like body 22 is first wound around the string-like body housing portion 27 and stored, as shown in Figure 6. When the cord-like body 22 has been housed in the cord-like body housing section 27, the intermediate section 23 of the power supply cable 2 is located between a plurality of protruding members 34 arranged circumferentially along the rotation axis direction P, as shown by the dashed line in Figure 3. Therefore, the tip end portion and the base end portion of the power supply cable 2, separated by the intermediate section 23, are distributed to both outer sides P2 of the rotation axis direction P of the cord-like body housing section 27. Then, by further rotation of the drum section 21 after winding the cord-like body 22 around the cord-like body housing section 27, the power supply cable 2 is wound around and housed in the cable housing section 28 in a manner that distributes the tip end portion and the base end portion of the power supply cable 2, separated by the intermediate section 23, to both outer sides P2 of the rotation axis direction P of the cord-like body housing section 27.

[0039] With the above steps completed, the winding operation of the power supply cable 2 by the vehicle power supply cable winder 3 is finished (see Figure 1). In this embodiment, the tip portion 22A of the string-like body 22 is connected to the intermediate portion 23 of the power supply cable 2 at approximately half the length of the usable portion 2B. As a result, the tip portion and the base portion of the power supply cable 2, separated by the intermediate portion 23, are approximately the same length, and substantially the entire tip portion and base portion can be appropriately housed in the cable housing portion 28 of the vehicle power supply cable winder 3.

[0040] As shown in Figure 7, the power supply pole 1 is configured to allow the attachment of a cover 38 that covers the pole outlet 11, control box 9, etc. In this embodiment, the cover 38 is configured to be attachable to the pole portion 5 and includes an outlet cover portion 41 that covers the pole outlet 11, a box holder cover portion 42 that covers the box holder 13 and the control box 9 held by the box holder 13, and an excess length portion winding storage portion cover portion 43 that covers the excess length portion winding storage portion 4 and the excess length portion winding storage portion 2A housed in the excess length portion winding storage portion 4. The outlet cover portion 41, the box holder cover portion 42, and the excess length portion winding storage portion cover portion 43 can be configured as a single unit or as separate parts.

[0041] [Another embodiment] Other embodiments of the present invention will now be described. Note that the configurations of each embodiment described below are not limited to being applied individually, but can also be applied in combination with the configurations of other embodiments.

[0042] (1) In the above embodiment, the cover 38 was described as having a configuration comprising an outlet cover portion 41, a box holder cover portion 42, and an excess length winding storage portion cover portion 43. However, the configuration of the cover 38 may be changed as appropriate, and as shown in Figure 8, the cover 38 may have a configuration comprising, in addition to the outlet cover portion 41, the box holder cover portion 42, and the excess length winding storage portion cover portion 43, a winding machine cover portion 45 that covers the vehicle power supply cable winding machine 3 and the usable portion 2B housed in the vehicle power supply cable winding machine 3, and a connector holder cover portion 44 that covers the connector holder 12 and the upper part of the charging connector 8 connected to the connector holder 12.

[0043] In this case, as shown in Figure 8, the connector holder 12 may be attached to the pole portion 5 so as to connect the charging connector 8 from the front side X1. When the connector holder 12 is configured in this way, the power supply cable 2 will extend from the connected charging connector 8 toward the front side X1 and diagonally downward Z2. As a result, the charging connector 8 and the power supply cable 2 extending from the charging connector 8 are less likely to interfere with the operating handle 25 of the drum portion 21, and the vehicle power supply cable winder 3 can be brought as close as possible to the charging connector 8. Thus, the vehicle power supply cable winder 3 can be mounted in a relatively high position that makes winding easier, and the connector holder cover portion 44 and the winder cover portion 45 can be easily integrated into one unit.

[0044] (3) In the above embodiment, the example given was that the vehicle to be powered is an electric vehicle, but the vehicle to be powered may also be an electric motorcycle, electric bicycle, electric wheelchair, or any other vehicle that requires power supply.

[0045] (4) In the above embodiment, the power supply pole 1 is configured such that a pole outlet 11 can be attached to the pole portion 5, and the power supply cable 2 is connected to the power supply pole 1 by the attached pole outlet 11.
