  • Publication number: 20240159093
    Abstract: A lid opening/closing device includes: a base member provided with an opening; a lid configured to open/close the opening; and a positioning portion configured to position at least a vertical position of the lid relative to the base member at a closed position of the lid. The positioning portion includes an engagement recess portion provided to the base member in a recess shape, and an engagement projection portion provided to the lid in a projection shape and configured to be engaged with the engagement recess portion at least in an up-down direction at the closed position of the lid. The engagement recess portion includes a rib extending in the up-down direction at the closed position of the lid. The rib is engaged at a distal end thereof with the engagement projection portion at the closed position of the lid.

  • Publication number: 20240157783
    Abstract: A lid opening/closing device includes a lid box, a lid, and an opening/closing mechanism. The opening/closing mechanism includes, as a link interposed between the lid box and the lid, a main arm rotatably supported on the lid box at one main arm end portion thereof and an auxiliary arm configured to restrict a posture of the lid during opening/closing of the lid so as to keep the lid in a predetermined posture by rotating in conjunction with rotation of the main arm. The main arm includes an arm-side restriction portion configured to come into contact with a back surface side of the lid at an opened position of the lid to restrict the main arm from rotating to an open side. An axial length of the arm-side restriction portion is longer than an axial length of the one main arm end portion.

  • Publication number: 20240140194
    Abstract: A lid opening/closing device includes an actuator configured to generate first power for opening a lid, an external force operation mechanism configured to convert an external force into second power for opening the lid, and a power transmission mechanism configured to transmit the first and second power to the lid. The power transmission mechanism includes a first shaft configured to rotate by the first and second power, and a second shaft configured to open/close the lid by the rotation of the first shaft. The external force operation mechanism includes a rotation member. The power transmission mechanism includes an engagement switching portion. The rotation member is integrally incorporated into the power transmission mechanism, and is placed on a side, which is the same as a side on which the first shaft is placed, with respect to the actuator.

  • Publication number: 20240100940
    Abstract: In a lid assembly structure 1 which includes a base member 2, a lid 3, and an opening/closing mechanism 5 and in which the opening/closing mechanism 5 includes a biasing member 8, during assembling of the base member 2 and the opening/closing mechanism 5, the biasing member 8 is guided by a guide portion 90 which is a part of the opening/closing mechanism 5, and a state of the biasing member 8 is changed from a temporary assembled state where a second engagement end 82 of the biasing member 8 and a temporary engagement portion 93 engage with each other to a main assembled state where the second engagement end 82 and a main engagement portion 91 of a mating member engage with each other, thereby accumulating at least a part of a biasing force in the biasing member 8.

  • Publication number: 20230373293
    Abstract: This vehicle lid device includes: a box attached to a vehicle-body side surface portion, and including a storage space storing a vehicle-energy supply port, a communication hole for the storage space and a vehicle-body deep side to communicate with each other, and an opening for exposing the supply port to a vehicle-body outside; a lid to open/close between opening-closed/opened positions; and an open/close mechanism interposed between the box and the lid, for opening/closing the lid relative to the box about an axis line on an upper-periphery side of the opening. The open/close mechanism includes a plate-shaped hinge arm extending in a direction including an axial direction of the axis line, and covering a box-lid gap formed above the opening in a lid-opened state. Both axial-direction ends of the hinge arm are respectively located on axial-direction outer sides relative to axial-direction periphery ends of the supply port or the communication hole.

  • Publication number: 20230087162
    Abstract: This driving device for energy replenishment port visor member includes: a visor member which advances/retracts between an advanced position for covering, from above, a replenishment port exposed at a vehicle-body-side opening and used for replenishing a vehicle with energy, and a retracted position where the visor member is retracted from above the replenishment port; a visor driving unit which advances/retracts the visor member between the advanced position and the retracted position; a gun connection detection unit which detects whether or not an energy replenishment gun is connected to the replenishment port; and a control unit which causes the visor driving unit to execute advancing-driving for advancing the visor member from the retracted position to the advanced position, when the gun connection detection unit has detected that the energy replenishment gun is connected to the replenishment port in a state in which the visor member is at the retracted position.
