Fig. 13 shows a cross-section taken along line XIII-XIII in Fig. 12.

[0012] As shown in Fig. 1, the vehicle charging device 1 of this embodiment is a device that charges a vehicle 200. The vehicle charging device 1 is placed on a floor 100 of a charging stand, parking lot, or the like. A charging inlet 210 is placed under the vehicle 200. The vehicle charging device 1 has an apparatus main body 2 that charges the vehicle 200, a guide member 10, and a cover structure 20. As will be described later, the cover structure 20 is configured to cover the portion of the guide member 10 that protrudes from the apparatus main body 2.

[0013] The device main body 2 has a housing 2a, a movement mechanism 4, and a connector 5. The housing 2a houses components including the movement mechanism 4 and the connector 5. The housing 2a is, for example, shaped like a rectangular parallelepiped. The connector 5 is a charging connector that fits into the inlet 210. The charging circuit of the vehicle charging device 1 is connected to the battery of the vehicle 200 via the connector 5.

[0014] The movement mechanism 4 is a mechanism for fitting the connector 5 with the inlet 210. The movement mechanism 4 is configured to move the connector 5 in three directions. The three directions are a first direction X shown in FIG. 2, a second direction Y shown in FIG. 1, and an up-down direction Z. The first direction X corresponds, for example, to the width direction of the vehicle 200. The second direction Y corresponds, for example, to the front-to-rear direction of the vehicle 200. The up-down direction Z corresponds to the up-down direction of the vehicle 200. The first direction X is perpendicular to the second direction Y. The up-down direction Z is perpendicular to both the first direction X and the second direction Y.

[0015] The movement mechanism 4 moves the connector 5 in the vertical direction Z by, for example, an arm. The movement mechanism 4 moves the connector 5 in the first direction X and the second direction Y by, for example, a rack and pinion mechanism.

[0016] 2, the movement mechanism 4 has a guide member 10, a pinion gear 41, and a motor 42. The guide member 10, the pinion gear 41, and the motor 42 constitute a mechanism for moving the housing 2a in the first direction X. The guide member 10 is fixed to a floor portion 100 and extends in the first direction X.

[0017] The guide member 10 is a linearly extending member and has a rack gear portion 11 and a pair of fixed portions 12. The rack gear portion 11 has a plurality of gear teeth aligned in a first direction X. The fixed portions 12 are portions that are fixed to the floor portion 100. The fixed portions 12 are fixed to a base 110 placed on the floor portion 100, for example, by fastening members. The fixed portions 12 are arranged at both ends of the guide member 10 in the first direction X. The rack gear portion 11 is arranged between the two fixed portions 12.

[0018] The pinion gear 41 is a disk-shaped gear that meshes with the rack gear portion 11. The motor 42 is a drive source that rotates the pinion gear 41. The motor 42 is fixed to the housing 2a. The motor 42 may be connected to the pinion gear 41 via a speed reduction mechanism. As the pinion gear 41 rotates, the housing 2a and the connector 5 move in the first direction X.

[0019] 2 shows device main body 2 positioned at a standby position. The standby position is a position where vehicle charging device 1 is in a standby state before starting charging of vehicle 200. When starting charging, vehicle charging device 1 detects the position of inlet 210 and causes movement mechanism 4 to move connector 5 to a position where connector 5 can be mated with inlet 210.

[0020] The movement mechanism 4 can move the device body 2 to both sides of the first direction X relative to the standby position. When the device body 2 is in the standby position, the rack gear unit 11 is covered and hidden by the housing 2a. In other words, the rack gear unit 11 is housed in the housing 2a in the standby position. The housing 2a in the standby position may house the entire guide member 10.

[0021] The guide member 10 of this embodiment is disposed so that a portion of the guide member 10 protrudes from the device main body 2 when the device main body 2 moves in the first direction X. In other words, when the device main body 2 moves in the first direction X, a portion of the guide member 10 is exposed to the external space of the housing 2a. In the vehicle charging device 1 of this embodiment, at least a portion of the rack gear portion 11 may be exposed to the external space of the housing 2a. If the guide member 10 protruding from the housing 2a is exposed to the external space without being covered, foreign matter such as mud or dirt may adhere to the guide member 10.

[0022] The vehicle charging device 1 of this embodiment protects the guide member 10 with a cover structure 20, which will be described below. FIG. 3 shows a cross section of the vehicle charging device 1 perpendicular to the second direction Y. As shown in FIG. 3 and other figures, the vehicle charging device 1 of this embodiment has a cover structure 20 that covers and protects the guide member 10. The cover structure 20 has a cover body 21, a locking portion 22, a locked portion 23, and a winding mechanism 6.

[0023] The cover body 21 is a flexible plate-like member. The cover body 21 is made of a material such as metal, resin, or rubber. The cover body 21 is formed in a tape shape and is wound by or unwound from the winding mechanism 6. The locked portion 23 is attached to the tip of the cover body 21. The locked portion 23 is a member that is locked by the locking portion 22. The illustrated locked portion 23 has a recess 23a that fits with the locking portion 22. The recess 23a is open toward the first direction X. The shape of the locked portion 23 in the cross section shown in FIG. 3 is substantially U-shaped.

[0024] The locking portion 22 is disposed at an end of the guide member 10 in the first direction X. The illustrated locking portion 22 is fixed to the fixed portion 12. The tip of the locking portion 22 protrudes from the fixed portion 12 in the first direction X. The illustrated locking portion 22 has a rod-like or plate-like shape that can be inserted into the recess 23a of the locked portion 23.

[0025] The winding mechanism 6 can wind up the cover body 21 and unwind the cover body 21 in response to an external force acting on the cover body 21. The winding mechanism 6 includes a rotating body 61 and a roller 62. The rotating body 61 is a member around which the cover body 21 is wound and is rotatably supported. The rotating body 61 has a cylindrical shape and has an outer circumferential surface 61b around which the cover body 21 is wound. A rotation shaft 61a of the rotating body 61 extends in the second direction Y. The winding mechanism 6 has a spring that applies a biasing force to the rotating body 61 in the rotational direction to wind up the cover body 21.

[0026] The roller 62 changes the extension direction of the cover body 21. The roller 62 is disposed between the rotating body 61 and the locked portion 23. That is, the portion of the cover body 21 between the rotating body 61 and the locked portion 23 is wound around the roller 62. The roller 62 in this embodiment is disposed so that the cover body 21 is pulled downward from the rotating body 61. The roller 62 is also disposed so that the cover body 21 extends in the first direction X from the roller 62 toward the locked portion 23.

[0027] 3 shows the cover structure 20 when the device main body 2 is in the standby position. The locked portion 23 is fitted with and locked by the locking portion 22. The locked portion 23, the cover body 21, and the winding mechanism 6 are covered from above by the housing 2a and are housed in the housing 2a.

[0028] The device body 2 is movable from a standby position to a first side X1 and a second side X2 in a first direction X. FIG. 4 shows the device body 2 moved from the standby position to the first side X1. When the device body 2 moves to the first side X1, the guide member 10 protrudes from the device body 2. In other words, the first side X1 is the side that increases the length of the portion 10x of the guide member 10 protruding from the device body 2. When the device body 2 moves to the first side X1, the fixing portion 12 protrudes from the device body 2 first. When the device body 2 moves further to the first side X1, the rack gear portion 11 protrudes from the device body 2. In FIG. 4, the rack gear portion 11 protrudes from the device body 2.

[0029] When the device main body 2 moves from the standby position to the first side X1, the locking portion 22 locks the locked portion 23. By restricting the movement of the locked portion 23 to the first side X1, the cover body 21 is unwound from the winding mechanism 6. The unwound cover body 21 covers the guide member 10 from above and protects the guide member 10. The cover body 21 covers the rack gear portion 11 and prevents foreign matter from entering the rack gear portion 11.

[0030] 5, the width W1 of the cover body 21 is equal to or larger than the width W2 of the guide member 10. The width W1 of the cover body 21 is preferably larger than the width W2 of the guide member 10. The cover body 21 may protrude in the second direction Y relative to the guide member 10. The cover body 21 of this embodiment can appropriately protect the rack gear portion 11 and the fixed portion 12 from foreign matter.

[0031] The second side X2 is opposite to the first side X1. When the device body 2 moves from the position shown in FIG. 4 to the second side X2, the guide member 10 is accommodated in the device body 2. In other words, the second side X2 is the side on which the length of the portion 10x of the guide member 10 protruding from the device body 2 is reduced. When the device body 2 moves to the second side X2 toward the standby position, the winding mechanism 6 winds the cover body 21 onto the rotating body 61.

[0032] 6 shows the device body 2 having moved further from the standby position toward the second side X2. When the device body 2 moves from the standby position toward the second side X2, the locked portion 23 disengages from the locking portion 22. The locked portion 23 disengages from the locking portion 22 and moves toward the second side X2 together with the device body 2.

[0033] The housing 2a may have a support portion that supports the locked portion 23 that has been released from the locking portion 22. For example, as shown in FIG. 7, the housing 2a may have a support portion 2b that guides the locked portion 23. The illustrated support portion 2b has a substantially L-shape when viewed from the first direction X. The support portion 2b supports the piece portion 23b of the locked portion 23 from below. The support portion 2b faces the piece portion 23b from both sides in the second direction Y and positions the locked portion 23 in the second direction Y. The piece portion 23b is slidable relative to the support portion 2b in the first direction X. The support portion 2b may have a stopper that locks the locked portion 23 against the winding force of the winding mechanism 6. The support portion 2b holds the locked portion 23 at a position where it can be fitted with the locking portion 22. Therefore, when the device main body 2 returns from the position shown in FIG. 6 to the standby position, the locked portion 23 fits into the locking portion 22.

[0034] As shown in FIG. 2 , the vehicle charging device 1 of this embodiment has two cover structures 20. The two cover structures 20 are configured similarly. That is, when the guide member 10 is exposed to the external space due to movement of the device main body 2, the two cover structures 20 unfold the cover body 21 to cover the guide member 10 with the cover body 21. Furthermore, when the guide member 10 is housed in the housing 2a due to movement of the device main body 2, the two cover structures 20 wind up the cover body 21 around the rotating body 61. Furthermore, when the device main body 2 moves toward the second side X2 from the standby position, the two cover structures 20 disengage the locked portion 23 from the locking portion 22 to follow the movement of the device main body 2. In the vehicle charging device 1 of this embodiment, when one cover structure 20 unfolds the cover body 21 to cover the guide member 10, the other cover structure 20 moves together with the device main body 2 with the cover body 21 housed in the housing 2a.

[0035] Therefore, in the vehicle charging device 1 of this embodiment, the guide member 10 can be protected by the cover body 21 when the device main body 2 moves from the standby position to either side in the first direction X. Furthermore, the locked portion 23 of the cover structure 20 is configured to be detachable from the locking portion 22. Therefore, when the device main body 2 moves to the second side X2, the cover structure 20 of this embodiment can move together with the device main body 2 without interfering with the movement of the device main body 2.

[0036] Next, another cover structure 20 according to the embodiment will be described. As shown in FIG. 8, the cover body 21 of the cover structure 20 may be composed of multiple sliding bodies 50. The sliding bodies 50 have a semi-cylindrical shape and cover the guide member 10 from above and from the sides. The sliding bodies 50 are formed, for example, in the shape of a rectangular gutter. As shown in FIG. 8, the sliding body 50 has a top wall 50a and side walls 50b. The top wall 50a is a wall portion that covers the guide member 10 from above. The side walls 50b are wall portions that cover the guide member 10 from the sides. As shown in FIG. 9, the sliding body 50 has side walls 50b on both sides of the guide member 10 in the second direction Y.

[0037] The multiple slide bodies 50 are slidable relative to one another along the first direction X. The illustrated cover body 21 has four slide bodies 50. The four slide bodies 50 include a first slide body 51, a second slide body 52, a third slide body 53, and a fourth slide body 54. The first slide body 51 is a distal slide body that constitutes the distal end of the cover body 21. The spacing W3 between the side walls 50b of the first slide body 51 is greater than the width W2 of the guide member 10. The first slide body 51 is locked by the locking portion 22 of the guide member 10. The locking portion 22 that locks the cover body 21 in FIG. 8 is an end face of the guide member 10 in the first direction X.

[0038] The first sliding body 51 has a locked portion 23 that is locked by the locking portion 22. The locked portion 23 is a piece that protrudes inward from an end portion of the first sliding body 51 on the second side X2. The locked portion 23 faces the locking portion 22 in the first direction X and is locked by the locking portion 22.

[0039] 9, the plurality of slide bodies 50 constitute a telescopic cover body 21 that is extendable and retractable in the first direction X. The second slide body 52 is formed so that the first slide body 51 can be accommodated therein. The third slide body 53 is formed so that the second slide body 52 can be accommodated therein. The fourth slide body 54 is formed so that the third slide body 53 can be accommodated therein.

[0040] Each slide body 50 has contact portions 50c, 50d. The contact portion 50c is a piece that protrudes outward from an end of the slide body 50 on the first side X1 in the second direction Y. The contact portion 50d is a piece that protrudes inward from an end of the slide body 50 on the second side X2 in the second direction Y. The contact portion 50d of the first slide body 51 functions as the locked portion 23 that is locked by the guide member 10.

[0041] The contact portion 50c of the first slide body 51 faces the contact portion 50d of the second slide body 52 in the first direction X. When the cover body 21 extends, the contact portion 50c of the first slide body 51 and the contact portion 50d of the second slide body 52 come into contact with each other. Similarly, the contact portion 50c of the second slide body 52 comes into contact with the contact portion 50d of the third slide body 53, and the contact portion 50c of the third slide body 53 comes into contact with the contact portion 50d of the fourth slide body 54.

[0042] The housing 2a has an opening 2e through which the cover body 21 can extend. The opening 2e is provided in an outer wall of the housing 2a facing the first direction X. The cover body 21 can extend into the external space of the housing 2a through the opening 2e.

[0043] The abutting portion 50c of the fourth slide body 54 is engaged by the first locking portion 2c and the second locking portion 2d of the housing 2a. The first locking portion 2c is disposed on the second side X2 of the abutting portion 50c of the fourth slide body 54 and faces the abutting portion 50c in the first direction X. The first locking portion 2c is, for example, part of a wall portion forming the opening 2e. The second locking portion 2d is disposed on the first side X1 of the abutting portion 50c of the fourth slide body 54 and faces the abutting portion 50c in the first direction X.

[0044] The second locking portions 2d are configured to face the contact portions 50c of the respective slide bodies 50. That is, the second locking portions 2d are arranged so as to be able to lock the contact portions 50c of the first slide body 51 to the fourth slide body 54.

[0045] 10 and 11 show the cover body 21 when the device main body 2 is in the standby position. When the device main body 2 is in the standby position, the cover body 21 is fully contracted and accommodated inside the housing 2a. As shown in FIG. 11, the four sliding bodies 51, 52, 53, and 54 are nested and overlap each other. The cover body 21 is accommodated in the accommodation space formed between the first locking portion 2c and the second locking portion 2d. The locking portion 22 locks the locked portion 23 to restrict movement of the first sliding body 51 toward the first side X1.

[0046] When the device main body 2 moves from the standby position toward the first side X1, the cover body 21 extends from the housing 2a as shown in FIG. 12. When substantially the entire cover body 21 extends from the housing 2a, the first locking portion 2c of the housing 2a abuts against the abutting portion 50c of the fourth sliding body 54 as shown in FIG. 13. The first locking portion 2c of the housing 2a presses the fourth sliding body 54 toward the first side X1. As a result, the fourth sliding body 54 moves toward the first side X1, following the housing 2a. At this time, the locked portion 23 of the first sliding body 51 is locked by the locking portion 22 of the guide member 10.

[0047] When the device main body 2 moves further toward the first side X1, the abutment portion 50d of the fourth slide body 54 abuts against the abutment portion 50d of the third slide body 53. As a result, the third slide body 53 moves toward the first side X1, following the housing 2a and the fourth slide body 54. In this manner, the cover body 21 extends toward the first side X1 while following the movement of the housing 2a, and covers the guide member 10. When the housing 2a moves to the end of the first side X1 in its movable range, the cover body 21 reaches its most extended state, as shown in FIGS. 8 and 9.

[0048] When the housing 2a moves from the state in which the cover body 21 is extended to the second side X2, the second locking portion 2d of the housing 2a abuts against the abutment portion 50c of the sliding body 50, compressing the cover body 21. When the housing 2a moves to the standby position, all of the sliding bodies 50 are housed inside the housing 2a.

[0049] 14 shows the cover body 21 when the housing 2a has moved from the standby position to the second side X2. In this case, the second locking portion 2d of the housing 2a comes into contact with the cover body 21, moving the cover body 21 to the second side X2. As the cover body 21 moves, the locked portion 23 of the cover body 21 disengages from the locking portion 22 of the guide member 10. When the locked portion 23 disengages from the locking portion 22, the cover body 21 moves to the second side X2 together with the device main body 2 while being housed in the housing 2a.

[0050] As described above, the vehicle charging device 1 of this embodiment has the device main body 2 that charges the vehicle 200, the linear guide member 10, and the cover structure 20 that covers the guide member 10. The guide member 10 extends in the first direction X and guides the movement of the device main body 2 along the first direction X. The guide member 10 is arranged so that a portion of the guide member 10 protrudes from the device main body 2 when the device main body 2 moves in the first direction X.

[0051] The cover structure 20 has a cover body 21 and a locking portion 22. The cover body 21 covers a portion 10x of the guide member 10 that protrudes from the device main body 2. The locking portion 22 is arranged at an end of the guide member 10 in the first direction X. The locking portion 22 is configured to lock the tip of the cover body 21. When the device main body 2 moves with the tip of the cover body 21 locked by the locking portion 22, the cover body 21 extends from the device main body 2 and covers the guide member 10. The vehicle charging device 1 of this embodiment can protect the guide member 10 by the cover structure 20.

[0052] The cover body 21 is, for example, a flexible plate-like member. In this case, the cover structure 20 may have a winding mechanism 6 that winds up the cover body 21. The device body 2 moves to a first side X1 or a second side X2. The first side X1 is a side that increases the length of the portion 10x of the guide member 10 that protrudes from the device body 2. The second side X2 is a side that decreases the length of the portion 10x of the guide member 10 that protrudes from the device body 2.

[0053] The winding mechanism 6 unwinds the cover body 21 when the device main body 2 moves to the first side X1, and winds up the cover body 21 when the device main body 2 moves to the second side X2. With this configuration, the cover body 21 can be stored compactly.

[0054] The cover body 21 may be composed of, for example, a plurality of semi-cylindrical sliders 50 that slide relative to one another along the first direction X. In this case, the plurality of sliders 50 have a tip slider that forms a tip portion. The illustrated tip slider is a first slider 51. When the device main body 2 moves to the first side X1 with the first slider 51 locked by the locking portion 22, the plurality of sliders 50 extend from the device main body 2 and cover the guide member 10. With this configuration, the guide member 10 can be covered from the side.

[0055] The tip of cover body 21 may be detachable from locking portion 22. In this embodiment, locked portion 23 provided at the tip of cover body 21 is detachable from locking portion 22. When device main body 2 moves to second side X2 and the tip of cover body 21 is detached from locking portion 22, cover body 21 moves to second side X2 together with device main body 2 while being housed in device main body 2. By housing cover body 21 in device main body 2 in this way, the vehicle charging device 1 can be made smaller.

[0056] The guide member 10 protected by the cover structure 20 is not limited to a member having a rack gear portion 11. The protected guide member 10 may be, for example, a rail 13 shown in FIG. 15 . The rail 13 is a guiding rail in a linear guide. The device main body 2 has a carriage guided by the rail 13. The rail 13 extends linearly in the first direction X and guides the device main body 2. The vehicle charging device 1 may have a cover structure 20 that covers the rail 13.

[0057] The vehicle charging device 1 may have a cover body 25 shown in FIG. 16. The cover body 25 is fixed to the housing 2a and protrudes from the housing 2a in the first direction X like a canopy. The cover body 25 has a top wall 25a that covers the guide member 10 from above, and side walls 25b. The top wall 25a is inclined with respect to the first direction X so as to approach the floor 100 as it moves away from the device main body 2 in the first direction X. The cover body 25 extends from one end of the housing 2a to the other end in the second direction Y. Therefore, the cover body 25 can protect a wide area on the side of the housing 2a and prevent foreign matter from entering.

[0058] The cover body 25 is formed so as to be able to cover the portion 10x of the guide member 10 that protrudes from the device body 2 when the device body 2 moves to the first side X1. The length of the cover body 25 in the first direction X is determined, for example, according to the length of the movable range of the device body 2. The length of the cover body 25 is determined, for example, so that the cover body 25 can always cover the entire protruding portion 10x.

[0059] The contents disclosed in the above embodiments can be implemented in appropriate combinations. [Explanation of symbols]
