There is a demand for electrically opening and closing the power supply lid. However, in the lid device of Patent Document 1, since the connector lid is urged by the urging member when the power supply lid is closed, it is necessary to use a high-torque motor to open and close the power supply lid. Since such a motor is expensive, the lid device of Patent Document 1 has room for improvement in terms of cost.

SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle lid device that can secure the waterproofness of a power supply connector and reduce the cost by reducing the torque of a motor for opening and closing the lid.

According to the present invention, a cylindrical first accommodation portion arranged inside the vehicle so as to surround a charging port of a vehicle body panel can be moved between a closed position that closes the charging port and an open position that opens the charging port. Advantageously, an outer lid mounted within the first housing, a drive mechanism including a motor for moving the outer lid between the closed position and the open position, and an end located toward the charging port. A second accommodating portion having a cylindrical peripheral wall provided along the axis of the first accommodating portion so as to be positioned within the first accommodating portion; A closed position in which communication between the power supply connector attached to the second accommodating portion and the charging port side passing through the peripheral wall and the power supply connector side is cut off; an inner lid attached between the charging port and the power supply connector so as to allow rotation between an open position in which the charging port side and the power supply connector side are communicated; and a biasing member that biases the vehicle lid device. Here, the second accommodating portion having the cylindrical peripheral wall 23 provided along the axis of the first accommodating portion means that the axis of the first accommodating portion and the axis of the peripheral wall of the second accommodating portion extend parallel to each other. Both configurations and configurations extending in cross directions are included.

An outer lid that closes the charging port by a drive mechanism including a motor is disposed within the first housing portion, a power supply connector is disposed in a second housing portion provided within the first housing portion, and an inner lid is disposed between the charging port and the power feeding connector. is installed. Therefore, even if water enters the first housing portion, the inner lid blocks the water from entering the power feeding connector side of the second housing portion, so that the waterproofness of the power feeding connector can be ensured.

Since the inner lid is biased to the closed position by the biasing member, the driving mechanism only needs to electrically open and close the outer lid. Therefore, the torque of the driving motor can be reduced. Low torque motors are less expensive than high torque motors, thus reducing the costs associated with electrically opening and closing the outer lid.

The inner lid urged to the closed position by the urging member can be rotated to the open position by pressing from the outside of the vehicle. Therefore, it is possible to cope with automatic charging of an electric vehicle. Specifically, after the outer lid is rotated by the drive mechanism to open the charging port, the charging plug is inserted into the charging port from the outside of the vehicle, and the charging plug is pushed and rotated by the inner lid to open the charging plug. Can be automatically connected to the power supply connector. After charging is completed, the inner lid can be rotated to the closed position by the biasing force of the biasing member by pulling out the charging plug, and the outer lid can be rotated to the closed position by the driving mechanism.

In the vehicle lid device of the present invention, the waterproofness of the power supply connector can be ensured, and the torque of the motor for opening and closing the lid can be reduced to reduce the cost.

When the electric vehicle is parked at a predetermined position of the charging station and the open/close switch is operated, the ECU detects the switch operation and drives the lid device 10 to open. As a result, the motor 36 rotates forward, and the rotational force of the motor 36 is transmitted to the gear 38 via the drive shaft 37, causing the gear 38 to rotate counterclockwise in FIG. As the rotational force of the gear 38 is transmitted to the internal gear portion 39, the outer lid 30 in the closed position shown in FIG. 3 rotates to the open position shown in FIG.

Subsequently, the charging plug 5 is inserted from the charging port 2 . As a result, the pressing of the charging plug 5 rotates the open/close body 41 in the closed position to the open position shown in FIG. 4 against the biasing force of the biasing member 45 . By subsequently inserting the charging plug 5, the charging plug 5 is connected to the connection port 15a of the power supply connector 15, and charging is started.

When charging is completed, the charging plug 5 is pulled out from the charging port 2 (power supply connector 15). As a result, the pair of opening/closing members 41 are rotated to the closed position shown in FIG. Also, the ECU closes the lid device 10 . As a result, the motor 36 is reversed, and the rotational force of the motor 36 is transmitted to the gear 38 via the drive shaft 37, causing the gear 38 to rotate clockwise in FIG. As the rotational force of the gear 38 is transmitted to the internal gear portion 39, the outer lid 30 in the open position shown in FIG. 2 rotates to the closed position shown in FIG.

The lid device 10 configured in this manner has the following features.

An outer lid 30 that closes the charging port 2 by a drive mechanism 35 including a motor 36 is arranged in the first housing portion 21, and the power supply connector 15 is arranged in the second housing portion 22 provided in the first housing portion 21, An inner lid is attached between the charging port 2 and the power supply connector 15 . Therefore, even if water enters the first accommodation portion 21, the inner lid 40 blocks the water from entering the power supply connector 15 side of the second accommodation portion 22, so that the power supply connector 15 is waterproof. .

Since the inner lid 40 is biased to the closed position by the biasing member 45, the driving mechanism 35 only needs to electrically open and close the outer lid 30. FIG. Therefore, the torque of the driving motor 36 can be reduced. Since the low torque motor 36 is less expensive than the high torque motor, the costs associated with electrically opening and closing the outer lid 30 can be reduced.

The inner lid 40 urged to the closed position by the urging member 45 can be rotated to the open position by pressing from the outside of the vehicle. Therefore, it is possible to cope with automatic charging of an electric vehicle. Specifically, after rotating the outer lid 30 by the driving mechanism 35 to open the charging port 2 , the charging plug 5 is inserted into the charging port 2 , and the inner lid 40 is pressed by the charging plug 5 to rotate. , the charging plug 5 can be automatically connected to the power supply connector 15. After charging is completed, the inner lid 40 can be rotated to the closed position by the biasing force of the biasing member 45 by pulling out the charging plug 5 , and the outer lid 30 can be rotated to the closed position by the driving mechanism 35 .

A partition wall 24 is provided inside the peripheral wall 23 of the second accommodation portion 22 , and the inner lid 40 is attached to an opening edge 24 b of the partition wall 24 . The inner lid 40 attached inside the partition wall 23 does not interfere with the outer lid 30 attached inside the first housing portion 21 . Therefore, it is possible to prevent malfunctions due to interference between the two lids 30 and 40 .

The inner lid 40 has a pair of opening/closing members 41 arranged at opposite positions to the opening edge 24b of the opening 24a. Therefore, the space required for opening and closing the opening/closing body 41 is smaller than when one opening/closing body 41 is used. Therefore, the overall size of the lid device 10 including the second accommodating portion 22 can be reduced.

The pair of opening/closing bodies 41 is horizontally rotatable around a rotating shaft 32 extending in the vertical direction (Z direction). Therefore, since the load due to the weight of the pair of opening/closing bodies 41 is uniformly applied, the opening/closing operation of the pair of opening/closing bodies 41 can be stabilized.

A seal portion 42 is provided on the outer periphery of each of the pair of opening/closing bodies 41 . Further, when the pair of opening/closing bodies 41 is in the closed position, the opposing portions 42a of the pair of seal portions 42 are in contact with each other. Also, the seal portion 42 is in contact with the opening edge 24b of the opening portion 24a. Therefore, it is possible to greatly suppress the ingress of water from the inside of the first accommodation portion 21 to the inner side of the partition wall 24 of the second accommodation portion 22 .

The power supply connector 15 is arranged outside the rotation range of the inner lid 40 . That is, the power supply connector 15 is spaced apart from the inner lid 40 at the open position. Therefore, even if water enters inside the partition wall 24 of the second accommodation portion 22 from inside the first accommodation portion 21 , adhesion of water to the power supply connector 15 can be suppressed.

The peripheral wall 23 is provided with a water passage hole 23g that allows communication between the inside and the outside of the second accommodating portion 22 . Therefore, even if water enters from inside the first accommodation portion 21 to inside the inner lid 40 inside the second accommodation portion 22, the water does not accumulate in the second accommodation portion 22 and is discharged to the outside through the water flow hole 23g. can be drained to Therefore, it is possible to prevent water accumulated near the edge of the inner lid 40 from freezing in winter, for example, and hindering the opening and closing of the inner lid 40 .

A water passage hole 23g is formed at the lowest position of the inclined surface 23c1 of the lower wall portion 23c. Therefore, even if water enters inside the partition wall 24 of the second housing portion 22, it can be reliably discharged to the outside.

The outer lid 30 is rotatably mounted in the first housing portion 21, and the driving force of the motor 36 transmitted to the bearing portion 30d via the drive shaft 37, the gear 38, and the internal gear portion 39 causes the outer lid 30 to move to the closed position. Rotate to the open position. Since the outer lid 30 is rotated by the rotation of the drive shaft 37 that is separate from the rotating shaft 32 of the outer lid 30, the outer lid 30 can be rotated by directly transmitting the driving force to the rotating shaft 32. opening and closing can be stabilized.
