[0011] As shown in Fig. 1, a vehicle charging system 1 of this embodiment is placed on a floor 100 of a parking space where a vehicle is parked. As shown in Figs. 1 and 2, the vehicle charging system 1 has a main body 2, a housing 3, a sliding body 4, a connector unit 5, a first cover 10, a second cover 20, and a third cover 30.

[0012] The main body 2 is a base of the vehicle charging system 1 and is fixed to the floor 100. The illustrated main body 2 has a rectangular plate shape. The sliding body 4 is slidable in a first direction X relative to the main body 2. The first direction X is, for example, the front-rear direction of the vehicle to be charged. The first direction X is the longitudinal direction of the main body 2.

[0013] In the following description, the width direction of the main body 2 is referred to as the "second direction Y." The second direction Y is perpendicular to the first direction X. In addition, a direction perpendicular to both the first direction X and the second direction Y is referred to as the "third direction Z." The third direction Z is, for example, the vertical direction.

[0014] The sliding body 4 is supported by, for example, a rail arranged on the main body 2 along the first direction X. As shown in Fig. 2, the sliding body 4 has a base portion 41 and a frame portion 42. The base portion 41 is a member having a flat plate shape. The frame portion 42 is fixed to an upper surface of the base portion 41.

[0015] The frame 42 is disposed so as to surround the connector unit 5 from three sides. More specifically, the frame 42 has a pair of opposing walls 43 and a connecting wall 44. The pair of opposing walls 43 extend in a first direction X and face each other in a second direction Y. The connecting wall 44 connects ends of the pair of opposing walls 43 and extends in the second direction Y. The connecting wall 44 is disposed on the opposite side of the connector unit 5 from the main body 2 side. The base 41 and the frame 42 form an accommodation space 40 that accommodates devices of the vehicle charging system 1.

[0016] In the following description, the movement of the sliding body 4 away from the main body 2 along the first direction X is referred to as "advancing forward," and the movement of the sliding body 4 toward the main body 2 is referred to as "retreating." However, the front side X1 and the rear side X2 of the sliding body 4 in its advancement and retreat may be different from the front side and the rear side in the vehicle longitudinal direction.

[0017] The connector unit 5 has a connector 51 and an arm 52. The connector 51 is a fitting for charging that is connected to a vehicle. The connector 51 has a plurality of terminals that are connected to terminals on the vehicle side. The illustrated connector unit 5 has two arms 52 arranged on both sides of the connector 51 in the second direction Y. The two arms 52 face each other in the second direction Y. A base end 52a of the arm 52 is supported by the base portion 41 so as to be able to swing. The two base ends 52a are connected to each other by a rotating shaft. A tip end 52b of the arm 52 is connected to the connector 51 and supports the connector 51.

[0018] A motor 53 is disposed on the base unit 41 as a drive source. The motor 53 is connected to the rotation shaft of the arm 52 and can swing the arm 52. The arm 52 driven by the motor 53 rotates about the base end 52a as the center of rotation so as to move the connector 51 up and down. In the following description, the movement of the arm 52 that moves the connector 51 upward is referred to as "standing up." When standing up, the arm 52 rotates in a direction that moves the tip end 52b away from the base unit 41.

[0019] Fig. 2 shows the connector unit 5 with the arm 52 in the middle of standing up. The rotational position of the arm 52 shown in Fig. 2 is a position between a tilted position in which the connector 51 is positioned at the lowest position and an upright position in which the connector 51 is positioned at the highest position. The connector unit 5 is accommodated in the accommodation space 40 with the arm 52 in the tilted position.

[0020] The first cover 10 swings in conjunction with the swing of the arm 52 when the arm 52 stands up. FIG. 3 shows the arm 52 in a standing state. The first cover 10 may be pushed up by the arm 52, or may be opened and closed by torque transmitted from a drive source such as a motor 53. The first cover 10 covers the arm 52 from the side of the main body 2 while swinging in conjunction with the swing of the arm 52. In other words, the first cover 10 covers the standing arm 52 from the rear side X2. As shown in FIG. 1, the first cover 10 covers the connector unit 5 from above in a state in which the slide body 4 is housed in the main body 2.

[0021] As shown in Fig. 3, the connector 51 fits into the inlet 210 of the vehicle 200. The inlet 210 is a power receiving fitting disposed under the body of the vehicle 200. The connector 51 fits into the inlet 210 to be connected to the battery of the vehicle 200. The vehicle charging system 1 has a sensor that detects the inlet 210. A control unit of the vehicle charging system 1 controls the position of the sliding body 4, the height position of the connector 51, and the attitude of the connector 51 based on the detection result by the sensor.

[0022] As shown in FIG. 3 and other figures, the vehicle charging system 1 of this embodiment forms a frame 6 that surrounds the arm 52 when the arm 52 is standing. The frame 6 includes a second cover 20 and a third cover 30. The frame 6 can prevent foreign objects from entering the accommodation space 40 and protect components including the connector unit 5. The second cover 20 and the third cover 30 are configured to extend upward in conjunction with the swing of the arm 52 when the arm 52 stands up. In addition, the second cover 20 and the third cover 30 are configured to contract downward in conjunction with the swing of the arm 52 when the arm 52 is tilted.

[0023] As shown in FIG. 2 and FIG. 3, the second cover 20 has a plurality of overlapping constituent bodies 21. The constituent bodies 21 are plate-shaped and can slide relative to each other. The constituent body 21 has a main wall 21a and a pair of side walls 21b. The main wall 21a is a rectangular plate-shaped body and extends in the second direction Y. The constituent body 21 is bent at a right angle between the main wall 21a and the side wall 21b. The side walls 21b are provided at both ends of the constituent body 21. The pair of side walls 21b face each other in the second direction Y. The side walls 21b of each constituent body 21 are rotatably supported by the sliding body 4 and can rotate around an axis in the second direction Y.

[0024] The rotation of the motor 53 is transmitted to the second cover 20 via a sprocket or a chain. As shown in FIG. 3, the second cover 20 has a rotating member 22. The rotating member 22 is driven to rotate by the motor 53. The rotating member 22 is configured to drive and rotate the multiple components 21 in sequence. When the arm 52 stands up, the rotating member 22 rotates in conjunction with the swing of the arm 52, and rotates the multiple components 21 upward in sequence.

[0025] The first component 21 rotates upward while sliding against the second component 21. When the first component 21 rises to a predetermined position, the second component 21 starts to rotate. The second component 21 rotates upward while sliding against the third component 21. When the second component 21 rises to a predetermined position, the third component 21 starts to rotate. In this way, the second cover 20 is an expandable cover that expands in an arc shape as the multiple components 21 rotate sequentially while sliding against each other.

[0026] As shown in Fig. 2, the third covers 30 are disposed on both sides of the connector unit 5 in the second direction Y. The pair of third covers 30 face each other in the second direction Y with the connector unit 5 therebetween. Each third cover 30 has a plurality of overlapping constituent bodies 31. The constituent bodies 31 are plate-shaped and can slide relative to each other. The illustrated constituent body 31 is plate-shaped and extends in the first direction X.

[0027] In the third cover 30 of this embodiment, the components 31 are raised and lowered by a parallel link. The end 31a on the rear side X2 of each component 31 is connected to the arm 52. The end 31a may be indirectly connected to the arm 52. The end 31a is connected, for example, to a link 54 parallel to the arm 52. The link 54 is connected to the arm 52 and faces the arm 52 in the second direction Y. The front end 31b is connected to the link 32. The link 32 is rotatably supported by the sliding body 4 and configured to maintain parallelism with the arm 52. The link 32 may be driven by a motor 53 to rotate in synchronization with the arm 52.

[0028] The multiple constituent bodies 31 move up and down while being supported by the links 54 and 32. When the arm 52 stands up, the multiple constituent bodies 31 move upward in conjunction with the swinging of the arm 52. As a result, the third cover 30 extends upward while sliding the multiple constituent bodies 31. The third cover 30 is an expandable cover in which the multiple constituent bodies 31 extend upward while simultaneously rising. When the arm 52 tilts, the multiple constituent bodies 31 move downward in conjunction with the swinging of the arm 52. As a result, the third cover 30 contracts downward.

[0029] As shown in FIG. 1, the housing 3 has a fixed cover 7, a sliding cover 8, and an auxiliary cover 9. The housing 3 accommodates the sliding body 4 by covering it from above and from the sides. The fixed cover 7 is fixed to the main body 2. The fixed cover 7 is disposed in a portion of the main body 2 on the rear side X2. The sliding cover 8 is connected to the side of the fixed cover 7 with respect to the first cover 10. In other words, the sliding cover 8 is connected to an end of the first cover 10 on the rear side X2. The sliding cover 8 can slide in the first direction X together with the first cover 10. The first cover 10 is connected to the sliding cover 8 via a hinge, and swings while being supported by the sliding cover 8.

[0030] The auxiliary cover 9 is disposed between the sliding cover 8 and the fixed cover 7. For example, the auxiliary cover 9 is disposed between the sliding cover 8 and the fixed cover 7 in the first direction X. Also, the auxiliary cover 9 is disposed between the sliding cover 8 and the fixed cover 7 in the third direction Z. In other words, the auxiliary cover 9 overlaps the fixed cover 7 on the outside. The sliding cover 8 overlaps the auxiliary cover 9 on the outside.

[0031] 4, the sliding cover 8 and the auxiliary cover 9 are independent members and are relatively movable in the first direction X. A protrusion 91a is provided on a side wall 91 of the auxiliary cover 9. The protrusion 91a is disposed on an outer surface of the side wall 91 and extends in the third direction Z. The side wall 81 of the sliding cover 8 has a protrusion 81a that can come into contact with the protrusion 91a. The protrusion 81a is disposed on an inner surface of the side wall 81 that faces the auxiliary cover 9.

[0032] The sliding cover 8 and the first cover 10 are connected via a connecting portion 11. The connecting portion 11 has a hinge or the like, and connects the two so that the first cover 10 can swing relative to the sliding cover 8. The connecting portion 11 is fixed to a top wall 82 of the sliding cover 8. The connecting portion 11 is disposed at an end of the top wall 82 on the front side X1, and is capable of abutting against the auxiliary cover 9.

[0033] As shown in FIG. 5, the sliding cover 8 is disposed so as to cover the auxiliary cover 9 from the outside. FIG. 5 shows a movable range RX of the auxiliary cover 9. The movable range RX is a range along the first direction X, and is a range in which the auxiliary cover 9 can move relative to the sliding cover 8. The auxiliary cover 9 can move relative to the sliding cover 8 between the position shown in FIG. 5 and the position shown in FIG. 6. The position of the auxiliary cover 9 shown in FIG. 5 is a position where the protrusions 81a, 91a abut. The position of the auxiliary cover 9 shown in FIG. 6 is a position where the end face of the front side X1 of the auxiliary cover 9 abuts against the connecting portion 11.

[0034] When the slide cover 8 slides to the front side X1, a part of the auxiliary cover 9 protrudes from the slide cover 8 as shown in Fig. 5. A part of the auxiliary cover 9 protrudes from the slide cover 8 toward the rear side X2. As a result, the opening that occurs when the slide cover 8 slides is covered by the auxiliary cover 9, as described below.

[0035] First, the operation of the vehicle charging system 1 of this embodiment will be described. When the vehicle charging system 1 starts a charging operation, it slides the sliding body 4 to the front side X1 as shown in FIG. 7. At this time, the first cover 10 is locked and stopped. When the vehicle charging system 1 advances the sliding body 4 to a predetermined position, it unlocks the first cover 10. This allows the first cover 10 and the sliding cover 8 to slide together with the sliding body 4. The position of the arm 52 shown in FIG. 7 is a tilted position, and the connector unit 5 is accommodated in the accommodation space 40 surrounded by the frame portion 42. The second cover 20 and the third cover 30 are in a contracted state and stored inside the frame portion 42.

[0036] The vehicle charging system 1 detects the position of the inlet 210 by a sensor and determines a target position for the sliding body 4. The vehicle charging system 1 advances and retreats the sliding body 4 to the target position to position the connector unit 5 relative to the inlet 210. When the sliding body 4 advances and retreats, the first cover 10 and the sliding cover 8 advance and retreat together with the sliding body 4.

[0037] 8 shows a vehicle charging system 1R of the comparative example. The vehicle charging system 1R of the comparative example does not have the auxiliary cover 9. In this case, when the first cover 10 and the sliding cover 8 are moved to the frontmost side X1, an opening 3a is formed between the fixed cover 7 and the sliding cover 8.

[0038] 9, in the vehicle charging system 1 of this embodiment, the auxiliary cover 9 covers the opening 3a formed between the fixed cover 7 and the sliding cover 8, thereby shielding the opening 3a. The auxiliary cover 9 of this embodiment can prevent foreign objects from entering the inside of the housing 3.

[0039] When the vehicle charging system 1 stops the sliding body 4 at the target position, the arm 52 is raised to make the connector 51 face the inlet 210. As shown in FIG. 3, the second cover 20 and the third cover 30 extend upward to form a frame 6 surrounding the raised arm 52. The second cover 20 is located on the front side X1 with respect to the arm 52, and prevents foreign objects from entering from the front side X1. The third cover 30 is located on both sides of the arm 52 in the second direction Y, and prevents foreign objects from entering from the sides. The first cover 10 is located on the rear side X2 with respect to the arm 52, and prevents foreign objects from entering from the rear side X2. In this way, the vehicle charging system 1 of this embodiment has covers 10, 20, and 30 that surround the raised arm 52 from all sides.

[0040] The vehicle charging system 1 charges the battery of the vehicle 200 by fitting the connector 51 into the inlet 210. When charging is completed, the vehicle charging system 1 detaches the connector 51 from the inlet 210 and tilts the arm 52. The second cover 20 and the third cover 30 contract downward in conjunction with the swing of the tilting arm 52 and are stored in the accommodation space 40. The first cover 10 tilts in conjunction with the swing of the arm 52. When the connector unit 5, the second cover 20, and the third cover 30 are accommodated in the accommodation space 40, the vehicle charging system 1 locks the first cover 10 and retracts the sliding body 4, and accommodates the sliding body 4 in the main body 2. When the sliding body 4 retracts to the initial position shown in FIG. 1, the charging operation is completed.

[0041] The first cover 10 may have a side plate portion 12 as shown in Fig. 10. The side plate portion 12 covers the arm 52 from the outside in the second direction Y. The side plate portion 12 is composed of a plurality of plate members 13. The plurality of plate members 13 move upward while sliding against each other in conjunction with the swinging of the arm 52. As shown in Fig. 10, the second cover 20 and the side plate portion 12 may be disposed on the outside in the second direction Y with respect to the third cover 30.

[0042] As described above, the vehicle charging system 1 of this embodiment has the main body 2, the sliding body 4, the connector unit 5, the first cover 10, the second cover 20, and the third cover 30. The main body 2 is fixed to a floor 100 of a parking space where the vehicle is parked. The sliding body 4 is slidable in a first direction X relative to the main body 2. The connector unit 5 has a connector 51 connected to the vehicle, and an arm 52. A base end 52a of the arm 52 is supported by the sliding body 4 so as to be able to swing. A tip end 52b of the arm 52 supports the connector 51.

[0043] The first cover 10 covers the connector unit 5 from above when the sliding body 4 is housed in the main body 2. When the arm 52 stands up, the first cover 10 swings in conjunction with the swing of the arm 52 to cover the arm 52 from the side of the main body 2. The second cover 20 is supported by the sliding body 4, and is disposed on the opposite side of the connector unit 5 from the side of the main body 2. The third cover 30 is supported by the sliding body 4, and is disposed on both sides of the connector unit 5 in a second direction Y perpendicular to the first direction X.

[0044] When the arm 52 stands up, the second cover 20 and the third cover 30 extend upward in conjunction with the swing of the arm 52, forming a frame 6 that surrounds the arm 52. When charging the vehicle 200, the accommodation space 40 that accommodates the connector unit 5 and the drive mechanism is exposed to the outside space. In the vehicle charging system 1 of this embodiment, by surrounding the connector unit 5 with the frame 6, it is possible to prevent foreign objects from entering the accommodation space 40.

[0045] The illustrated frame 6 also encloses the drive mechanism that drives the connector unit 5. Thus, the frame 6 can protect the drive mechanism, such as the motor 53, sprockets, chains, and link mechanisms. The frame 6 may enclose a motor for sliding the slider 4. The frame 6 may enclose a control board that controls the drive mechanism. The frame 6 may enclose a sensor that detects the inlet 210.

[0046] The second cover 20 and the third cover 30 of this embodiment have a plurality of overlapping plate-like constituent bodies 21, 31. When the arm 52 stands up, the second cover 20 and the third cover 30 extend upward while sliding the plurality of constituent bodies 21, 31 in conjunction with the swinging of the arm 52. The second cover 20 and the third cover 30, which are constituted by the plurality of constituent bodies 21, 31, have a small size when stored.

[0047] The vehicle charging system 1 of this embodiment has a housing 3 that houses the sliding body 4 by covering the sliding body 4 from above and sides. The housing 3 includes a fixed cover 7, a sliding cover 8, and an auxiliary cover 9. The fixed cover 7 is fixed to the main body 2. The sliding cover 8 is connected to the side of the fixed cover 7 with respect to the first cover 10. The sliding cover 8 can slide in the first direction X together with the first cover 10. The auxiliary cover 9 is disposed between the sliding cover 8 and the fixed cover 7. The auxiliary cover 9 is configured to cover the opening 3a formed between the sliding cover 8 and the fixed cover 7 when the sliding cover 8 slides in a direction away from the fixed cover 7. Therefore, the vehicle charging system 1 of this embodiment can suppress the intrusion of foreign matter from the opening 3a.

[0048] The auxiliary cover 9 of this embodiment is slidable in the first direction X relative to each of the sliding cover 8 and the fixed cover 7. When the sliding cover 8 retreats toward the main body 2, the auxiliary cover 9 can be housed in the sliding cover 8 as shown in FIG. 6. This makes it possible to increase the movable range of the auxiliary cover 9 in the first direction X. For example, it becomes possible to retreat the sliding cover 8 to the rear end of the fixed cover 7.

[0049] The contents disclosed in the above embodiments can be implemented in appropriate combinations. [Explanation of symbols]
