[0039] [Implementation Method]

[0040] Reference Figures 1 to 10 The implementation method will be described below. This implementation method relates to a charging system for vehicles. Figure 1 This is a perspective view of the vehicle charging system according to the implementation method. Figure 2 This is a perspective view showing the internal structure of the vehicle charging system according to the embodiment. Figure 3 This is a side view of the vehicle charging system according to the embodiment. Figure 4 This is an exploded view of the housing involved in the implementation method.

Figure 8 This is a three-dimensional view of the vehicle charging system involved in the comparative example. Figure 9 This is a side view of the housing involved in the embodiment. Figure 10 This is a perspective view of the vehicle charging system according to the implementation method.

[0041] like Figure 1 As shown, the vehicle charging system 1 of this embodiment is disposed on the floor 100 of the parking space for parking vehicles. Figure 1 as well as Figure 2 As shown, 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.

[0042] The main body 2 is the base of the vehicle charging system 1 and is fixed to the floor 100. In this example, the main body 2 is a rectangular plate. The sliding body 4 is capable of sliding relative to the main body 2 along a first direction X. The first direction X is, for example, the longitudinal direction of the object being charged, i.e., the vehicle. The first direction X is also the longitudinal direction of the main body 2.

[0043] 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 orthogonal to the first direction X. In addition, the direction that is orthogonal 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.

[0044] The sliding body 4 is supported, for example, by a track arranged along the first direction X on the main body 2. Figure 2 As shown, the slider 4 has a base portion 41 and a frame portion 42. The base portion 41 is a flat plate-shaped component. The frame portion 42 is fixed to the upper surface of the base portion 41.

[0045] The frame portion 42 is configured to surround the connector unit 5 from three directions. More specifically, the frame portion 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 are opposite to each other in a second direction Y. The connecting wall 44 connects the ends of the pair of opposing walls 43 to each other and extends in the second direction Y. The connecting wall 44 is disposed on the side opposite to the main body 2 relative to the connector unit 5. The base portion 41 and the frame portion 42 form a receiving space 40, which receives the means of the vehicle charging system 1.

[0046] In the following description, moving the slider 4 away from the main body 2 along the first direction X is called "forward movement", and moving the slider 4 towards the main body 2 is called "reverse movement". However, the front side X1 and rear side X2 of the slider 4 when moving forward or backward may be different from the front side and rear side in the vehicle's forward and backward direction.

[0047] Connector unit 5 has connector 51 and arms 52. Connector 51 is a charging fitting for connection to a vehicle. Connector 51 has multiple terminals for connection to terminals on the vehicle side. The example connector unit 5 has two arms 52 disposed on both sides of the connector 51 in a second direction Y. The two arms 52 are opposite to each other in the second direction Y. The base end portion 52a of the arm 52 is supported by a base portion 41 and is able to swing. The two base end portions 52a are connected by a rotation axis. The end portion 52b of the arm 52 is connected to the connector 51 and supports the connector 51.

[0048] A motor 53, serving as a drive source, is disposed on the base portion 41. The motor 53 is connected to the rotation axis of the arm 52, enabling the arm 52 to swing. The arm 52, driven by the motor 53, rotates around the base end portion 52a as the center of rotation, causing the connector 51 to move up and down. In the following description, the movement of the arm 52 that moves the connector 51 upward will be referred to as "standing up". When the arm 52 is standing up, the end portion 52b rotates away from the base portion 41.

[0049] exist Figure 2 The connector unit 5 is shown in the middle of the arm 52. Figure 2 The rotational position of the arm 52 shown is between the tilted position where the connector 51 is positioned at its lowest point and the upright position where the connector 51 is positioned at its highest point. The connector unit 5 is accommodated in the receiving space 40 when the arm 52 is in the tilted position.

[0050] The first cover 10 swings in conjunction with the swing of the arm 52 when the arm 52 is raised. Figure 3 The image shows the arm 52 in an upright position. The first cover 10 can be pushed up by the arm 52 or opened and closed using torque transmitted from a drive source such as the motor 53. The first cover 10 covers the arm 52 from the main body 2 side while swinging in conjunction with the swing of the arm 52. In other words, the first cover 10 covers the upright arm 52 from the rear X2 side. Figure 1 As shown, the first cover 10 covers the connector unit 5 from above while the slider 4 is housed in the main body 2.

[0051] like Figure 3 As shown, connector 51 engages with socket 210 of vehicle 200. Socket 210 is a power receiving device disposed on the lower part of the vehicle body of vehicle 200. Connector 51 connects to the battery of vehicle 200 by engaging with socket 210. Vehicle charging system 1 has a sensor for detecting socket 210. The control unit of vehicle charging system 1 controls the position of slider 4, the height position of connector 51, and the orientation of connector 51 based on the detection results of the sensor.

[0052] like Figure 3 As shown, the vehicle charging system 1 of this embodiment forms a frame 6 surrounding the arm 52 when the arm 52 is upright. The frame 6 includes a second cover 20 and a third cover 30. The frame 6 can prevent foreign objects from intruding into the receiving space 40 and protect the components including the connector unit 5. The second cover 20 and the third cover 30 are configured to extend upward in conjunction with the swinging of the arm 52 when the arm 52 is upright. In addition, the second cover 20 and the third cover 30 are configured to retract downward in conjunction with the swinging of the arm 52 when the arm 52 is tilted.

[0053] like Figure 2 and Figure 3As shown, the second cover 20 has multiple overlapping structures 21. Each structure 21 is plate-shaped and can slide relative to each other. Each structure 21 has a main wall 21a and a pair of side walls 21b. The main wall 21a is a rectangular plate extending along the second direction Y. The structure 21 is bent at a right angle between the main wall 21a and the side walls 21b. The side walls 21b are located at both ends of the structure 21. The pair of side walls 21b are opposite each other in the second direction Y. The side walls 21b of each structure 21 are supported by a sliding body 4 in a rotatable manner and can rotate about the axis of rotation in the second direction Y.

[0054] The rotation of motor 53 is transmitted to the second cover 20 via a sprocket or chain. For example... Figure 3 As shown, the second cover 20 has a rotating component 22. The rotating component 22 is driven to rotate by a motor 53. The rotating component 22 is configured to sequentially drive multiple structures 21 to rotate. When the arm 52 is upright, the rotating component 22 rotates in conjunction with the swing of the arm 52, causing the multiple structures 21 to rotate upwards in sequence.

[0055] The first structure 21 slides relative to the second structure 21 while rotating upwards. When the first structure 21 rises to a predetermined position, the second structure 21 begins to rotate. The second structure 21 slides relative to the third structure 21 while rotating upwards. When the second structure 21 rises to a predetermined position, the third structure 21 begins to rotate. In this way, the second cover 20 is a telescopic cover that extends in an arc shape by causing multiple structures 21 to slide and rotate sequentially.

[0056] like Figure 2 As shown, the third cover 30 is disposed on both sides of the connector unit 5 in the second direction Y. A pair of third covers 30 are positioned opposite each other in the second direction Y, with the connector unit 5 placed between them. Each third cover 30 has a plurality of overlapping structures 31. The structures 31 are plate-shaped and can slide relative to each other. The example structure 31 is plate-shaped and extends in the first direction X.

[0057] In this embodiment, the third cover 30 uses parallel connecting rods to move the structure 31 up and down. The rear end 31a of each structure 31 (X2) is connected to the arm 52. The end 31a can also be indirectly connected to the arm 52. For example, the end 31a is connected to a connecting rod 54 parallel to the arm 52. The connecting rod 54 is connected to the arm 52 and is opposite to the arm 52 in the second direction Y. The front end 31b is connected to the connecting rod 32. The connecting rod 32 is supported by a sliding body 4 in a rotatable manner and is configured to remain parallel to the arm 52. The connecting rod 32 can also be driven by a motor 53 to rotate synchronously with the arm 52.

[0058] Multiple structures 31 move up and down while supported by connecting rods 54 and 32. When arm 52 is upright, the multiple structures 31 move upward in conjunction with the swing of arm 52. As a result, the third cover 30 extends upward while allowing the multiple structures 31 to slide. The third cover 30 is a telescopic cover that extends upward while the multiple structures 31 rise simultaneously. When arm 52 is tilted, the multiple structures 31 move downward in conjunction with the swing of arm 52. As a result, the third cover 30 retracts downward.

[0059] like Figure 1 As shown, the housing 3 has a fixed cover 7, a sliding cover 8, and an auxiliary cover 9. The housing 3 covers the sliding body 4 from above and the side to accommodate the sliding body 4. The fixed cover 7 is fixed relative to the main body 2. The fixed cover 7 is disposed on the rear X2 portion of the main body 2. The sliding cover 8 is connected to the fixed cover 7 side of the first cover 10. In other words, the sliding cover 8 is connected to the rear X2 end of the first cover 10. The sliding cover 8 can slide integrally with the first cover 10 in a first direction X. The first cover 10 is connected to the sliding cover 8 via a hinge and swings while being supported by the sliding cover 8.

[0060] An 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 a first direction X. Additionally, the auxiliary cover 9 is disposed between the sliding cover 8 and the fixed cover 7 in a third direction Z. In other words, the auxiliary cover 9 overlaps the fixed cover 7 on the outer side. The sliding cover 8 overlaps the auxiliary cover 9 on the outer side.

[0061] like Figure 4 As shown, the sliding cover 8 and the auxiliary cover 9 are independent components that can move relative to each other in the first direction X. A protrusion 91a is provided on the side wall 91 of the auxiliary cover 9. The protrusion 91a is disposed on the 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 abut against the protrusion 91a. The protrusion 81a is disposed on the inner surface of the side wall 81 opposite to the auxiliary cover 9.

[0062] The sliding cover 8 and the first cover 10 are connected via a connecting part 11. The connecting part 11 has a hinge or the like and connects the two in such a way that the first cover 10 can swing relative to the sliding cover 8. The connecting part 11 is fixed to the top wall 82 of the sliding cover 8. The connecting part 11 is disposed at the end of the front side X1 of the top wall 82 and can abut against the auxiliary cover 9.

[0063] like Figure 5 As shown, the sliding cover 8 is configured to cover the auxiliary cover 9 from the outside. Figure 5 The movable range RX of the auxiliary cover 9 is shown. The movable range RX is the range along the first direction X, and is the range in which the auxiliary cover 9 can move relative to the sliding cover 8. The auxiliary cover 9 is able to move from... Figure 5 The position shown is to Figure 6 The positions shown can move relative to the sliding cover 8. Figure 5 The position of the auxiliary cover 9 shown is where the protrusions 81a and 91a abut. Figure 6 The position of the auxiliary cover 9 shown is where the end face of the front side X1 of the auxiliary cover 9 abuts against the connecting part 11.

[0064] When the sliding cover 8 slides forward X1, as Figure 5 As shown, a portion of the auxiliary cover 9 protrudes from the sliding cover 8. This portion of the auxiliary cover 9 protrudes from the sliding cover 8 toward the rear X2. Thus, as explained below, the opening created during sliding is covered by the auxiliary cover 9.

[0065] First, the operation of the vehicle charging system 1 according to this embodiment will be explained. When the charging operation of the vehicle charging system 1 begins, as follows... Figure 7 The slider 4 is slid forward X1 as shown. At this time, the first cover 10 is locked and stops. When the vehicle charging system 1 moves the slider 4 to a predetermined position, it releases the lock on the first cover 10. Thus, the first cover 10 and the sliding cover 8 can slide together with the slider 4. Figure 7 The arm 52 shown is in a tilted position, and the connector unit 5 is housed in the receiving space 40 enclosed by the frame 42. The second cover 20 and the third cover 30 are in a retracted state and are housed inside the frame 42.

[0066] The vehicle charging system 1 uses sensors to detect the position of the socket 210 and determine the target position of the slider 4. The vehicle charging system 1 moves the slider 4 forward and backward to the target position to position the connector unit 5 relative to the socket 210. When the slider 4 moves forward and backward, the first cover 10 and the sliding cover 8 move forward and backward together with the slider 4.

[0067] exist Figure 8 The comparative example of a vehicle charging system 1R is shown. The comparative example of the vehicle charging system 1R does not have an auxiliary cover 9. In this case, when the first cover 10 and the sliding cover 8 move to the foremost side X1, an opening 3a is formed between the fixed cover 7 and the sliding cover 8.

[0068] In the vehicle charging system 1 of this embodiment, as follows: Figure 9 As shown, 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 suppress the intrusion of foreign objects into the interior of the housing 3.

[0069] When the vehicle charging system 1 stops the slider 4 at the target position, it raises the arm 52 so that the connector 51 is aligned with the socket 210. For example... Figure 3As shown, the second cover 20 and the third cover 30 extend upwards to form a frame 6 that surrounds the erected arm 52. The second cover 20 is located at the front X1 relative to the arm 52, preventing foreign objects from entering from the front X1. The third cover 30 is located on both sides of the arm 52 in the second direction Y, preventing foreign objects from entering from the side. The first cover 10 is located at the rear X2 relative to the arm 52, preventing foreign objects from entering from the rear X2. Thus, the vehicle charging system 1 of this embodiment has covers 10, 20, and 30 that surround the erected arm 52 from four directions.

[0070] The vehicle charging system 1 engages connector 51 with socket 210 to charge the battery of vehicle 200. Upon completion of charging, the vehicle charging system 1 disengages connector 51 from socket 210, causing arm 52 to tilt. Second cover 20 and third cover 30 retract downwards in conjunction with the tilting arm 52 and are housed in receiving space 40. First cover 10 tilts in conjunction with the tilting arm 52. When connector unit 5, second cover 20, and third cover 30 are housed in receiving space 40, the vehicle charging system 1 locks first cover 10, causing slider 4 to retract and be housed in body 2. When slider 4 retracts to... Figure 1 The charging process is complete at the initial position shown.

[0071] In addition, such as Figure 10 As shown, the first cover 10 may also have a side plate portion 12. 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 slide relative to each other in conjunction with the swinging motion of the arm 52 while moving upward. Figure 10 As shown, the second cover 20 and the side plate portion 12 can be disposed on the outside of the second direction Y relative to the third cover 30.

[0072] As described above, the vehicle charging system 1 of this embodiment includes a main body 2, a slider 4, a connector unit 5, a first cover 10, a second cover 20, and a third cover 30. The main body 2 is fixed to the floor portion 100 of the parking space for parking vehicles. The slider 4 is slidable relative to the main body 2 in a first direction X. The connector unit 5 includes an arm 52 and a connector 51 for connection to the vehicle. The base end portion 52a of the arm 52 is supported by the slider 4 in a swingable manner. The end portion 52b of the arm 52 supports the connector 51.

[0073] The first cover 10 covers the connector unit 5 from above when the slider 4 is housed in the main body 2. The first cover 10 covers the arm 52 from the side of the main body 2 while swinging in conjunction with the arm 52's movement when the arm 52 is erected. The second cover 20 is supported by the slider 4 and is disposed on the side opposite to the main body 2 relative to the connector unit 5. The third cover 30 is supported by the slider 4 and is disposed on both sides of the connector unit 5 in a second direction Y, orthogonal to the first direction X.

[0074] The second cover 20 and the third cover 30 extend upwards in conjunction with the swing of the arm 52 when the arm 52 is raised, forming a frame 6 that surrounds the arm 52. When charging the vehicle 200, the housing space 40 accommodating the connector unit 5 and the drive mechanism is exposed to the external space. By using the frame 6 to surround the connector unit 5, the vehicle charging system 1 of this embodiment can suppress the intrusion of foreign objects into the housing space 40.

[0075] The example frame 6 also surrounds the drive mechanism of the drive connector unit 5. Therefore, frame 6 can protect the drive mechanism, such as the motor 53, sprockets, chains, and linkages. Frame 6 can also surround the motor used to slide the slider 4. Frame 6 can also surround the control board that controls the drive mechanism. Frame 6 can also surround the sensor that detects the socket 210.

[0076] The second cover 20 and the third cover 30 of this embodiment have multiple overlapping plate-shaped structures 21 and 31. When the arm 52 is raised, the second cover 20 and the third cover 30 extend upwards while sliding the multiple structures 21 and 31 in conjunction with the swing of the arm 52. The second cover 20 and the third cover 30, which are composed of multiple structures 21 and 31, have a smaller volume when housed.

[0077] The vehicle charging system 1 of this embodiment has a housing 3 that covers and accommodates the sliding body 4 from above and the side. 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 fixed cover 7 side of the first cover 10. The sliding cover 8 can slide integrally with the first cover 10 in a first direction X. The auxiliary cover 9 is disposed between the sliding cover 8 and the fixed cover 7. The auxiliary cover 9 is configured such that when the sliding cover 8 slides away from the fixed cover 7, it covers the opening 3a formed between the sliding cover 8 and the fixed cover 7. Therefore, the vehicle charging system 1 of this embodiment can prevent foreign objects from entering through the opening 3a.

[0078] In this embodiment, the auxiliary cover 9 can slide relative to both the sliding cover 8 and the fixed cover 7 in the first direction X. When the sliding cover 8 retracts towards the main body 2, the auxiliary cover 9 can... Figure 6 The auxiliary cover 9 is housed in the sliding cover 8. This increases the range of motion of the auxiliary cover 9 in the first direction X. For example, the sliding cover 8 can be moved back to the rear end of the fixed cover 7.

[0079] The contents disclosed in the above-described embodiments can be appropriately combined and implemented.
