Lid opening and closing device

Abstract

To lock a lid while suppressing cost increase.SOLUTION: In a lid opening / closing device 10, an engagement receiving part 30 is provided on a base 20, and a lock member 70 is provided on a lid 40. A proximal end portion of the drive link 52 is rotatably connected to the base 20, and a distal end portion of the drive link 52 is connected to the drive link connecting portion 42 of the lid 40. When the drive link 52 is rotated to one side in the rotation direction by the actuator 60, the lid 40 moves from the open position to the closed position to close the opening portion 82. Here, the drive link coupling portion 42 couples the drive link 52 to the lid 40 so as to allow the relative rotation of the drive link 52 with respect to the lid 40 at the closed position of the lid 40, and when the drive link 52 rotates relative to the lid 40 to one side in the rotation direction, the lock member 70 is switched to the lock state by the drive link 52. Thus, the lock member 70 can be brought into the locked state by utilizing the actuator 60.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a lid opening and closing device. [Background technology]

[0002] In the energy receptacle device (lid opening / closing device) of Patent Document 1 below, a lid closes a recessed space of a receptacle port in an openable manner. The lid is opened and closed by an opening / closing mechanism, which includes a link mechanism and a motor. The link mechanism is actuated by driving the motor, causing the lid to open and close the recessed space. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-210473 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, the energy receptacle device does not include a locking mechanism that prevents the lid from moving when the lid is in the closed state. Therefore, from the perspective of improving the safety of the energy receptacle device, it is desirable to provide a locking mechanism in the energy receptacle device. For example, the closed state of the lid can be maintained by providing a locking mechanism that includes a locking member that prevents the lid from moving when the lid is in the closed state and a drive unit such as a motor that drives the locking member. In other words, the safety of the energy receptacle device can be improved by switching the locking member between a locked state that locks the lid and an unlocked state that unlocks the lid using the driving force of the drive member.

[0005] However, in this case, it is necessary to provide a separate drive unit for driving the locking member, which increases the cost of the energy receptacle device.

[0006] In consideration of the above circumstances, the present invention provides a lid opening and closing device that can lock a lid while suppressing an increase in cost. [Means for solving the problem]

[0007] One or more embodiments of the present invention include a base provided inside an opening in a panel of a vehicle; a lid configured to be movable between an open position that opens the opening and a closed position that closes the opening; an engagement receiving portion provided on one of the base and the lid; a locking member provided on the other of the base and the lid, which is actuated when the lid is in the closed position to engage with the engagement receiving portion to prevent movement of the lid, or to switch to an unlocked state in which engagement with the engagement receiving portion is released; a drive unit provided inside the panel; and a drive member having a base end rotatably connected to the base and a tip end a link having a portion connected to the lid and rotating in one direction about the base end by the driving force of the drive portion to move the lid from the open position to the closed position; and a connecting portion provided on the lid and connecting the tip end of the link, wherein the connecting portion connects the tip end of the link to the lid so as to allow the link to rotate relative to the lid at the closed position, and the link rotating in one direction relative to the lid at the closed position activates the locking member to switch from the unlocked state to the locked state. [Effects of the Invention]

[0008] According to one or more embodiments of the present invention, the lid can be locked while suppressing an increase in cost. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] (First embodiment) A lid opening / closing device 10 according to a first embodiment will be described below with reference to Figures 1 to 4. Note that the arrow UP shown in the drawings indicates the upper side of the vehicle to which the lid opening / closing device 10 is applied, and the arrow OUT indicates the outer side in the vehicle width direction. Also, the top of the paper in the drawings coincides with the rear side of the vehicle.

[0011] As shown in Figures 1 and 2, the lid opening and closing device 10 is provided on the rear side of the vehicle (on the right side of the vehicle in the example shown in Figure 1). The lid opening and closing device 10 includes a base 20, an engagement receiving portion 30, a lid 40, a link mechanism 50, and a locking member 70. Each component of the lid opening and closing device 10 will be described below.

[0012] (About Base 20) The base 20 is provided on the inner side in the vehicle width direction of an opening 82 provided in an outer panel 80 serving as a panel of the vehicle. The base 20 is formed in a concave shape that opens outward in the vehicle width direction. An energy receiving section (not shown) is provided in the base 20, and a portion of the energy receiving section is exposed from the base 20 to the outer side in the vehicle width direction.

[0013] (Regarding the engagement receiving portion 30) The engagement receiving portion 30 is provided at the lower part of the outer surface of the bottom wall of the base 20 in the vehicle width direction. When viewed from the rear, the engagement receiving portion 30 is formed in a generally U-shaped block shape that is open downward. That is, a receiving-side recess 30A that is open downward is formed in the middle part of the lower surface of the engagement receiving portion 30 in the vehicle width direction.

[0014] (About Lid 40) The lid 40 is formed in a substantially plate-like shape with its thickness direction aligned with the vehicle width direction. The lid 40 is configured to be movable between an open position (position shown in FIG. 1 ) in which the opening 82 is opened and a closed position (position shown in FIG. 3(B) ) in which the opening 82 is closed by a link mechanism 50 (described later). The lid 40 will be described below with the lid 40 in the open position. A drive link connecting portion 42 is provided at a lower portion of the back surface (inner surface in the vehicle width direction) of the lid 40 as a connecting portion for connecting a drive link 52 (described later) so as to be rotatable and relatively movable. A connecting groove 42A is formed in the drive link connecting portion 42 in the front-rear direction, and the connecting groove 42A is formed in the shape of an elongated hole extending substantially in the vehicle width direction in a rear view. Specifically, the connecting groove 42A extends in a direction slightly inclined downward as it extends outward in the vehicle width direction, and is formed to extend in an arc shape centered on the base end axis of the drive link 52.

[0015] A lock support portion 44 for rotatably supporting a lock member 70 (described later) is provided on the back surface of the lid 40 above the drive link connecting portion 42. The lock support portion 44 extends inward in the vehicle width direction from the lid 40. A driven link connecting portion 46 for rotatably connecting a driven link 56 (described later) is provided on the upper part of the back surface of the lid 40. The driven link connecting portion 46 extends inward in the vehicle width direction from the lid 40.

[0016] (Regarding the link mechanism 50) The link mechanism 50 is a mechanism that connects the base 20 and the lid 40 and moves the lid 40 between an open position and a closed position by actuation. The link mechanism 50 includes a drive link 52 and a driven link 56. The drive link 52 is formed in a substantially elongated plate shape with its thickness direction in the front-to-rear direction and is formed in a substantially U-shape that opens downward when viewed from the rear. Specifically, the drive link 52 includes a base end link portion 52A extending in the vertical direction, an intermediate link portion 52B extending outward in the vehicle width direction from an upper end of the base end link portion 52A, and a tip end link portion 52C extending downward from a tip end of the intermediate link portion 52B. A vehicle width directional intermediate portion of the intermediate link portion 52B is bent outward and downward in the vehicle width direction.

[0017] The lower end of the base link portion 52A (the base end of the drive link 52) is rotatably connected to the base 20 on the vehicle widthwise inner side of the outer panel 80, with the longitudinal direction as the axial direction. That is, although not shown, the base 20 extends to a position where the lower end of the base link portion 52A is connected. The intermediate link portion 52B is disposed within the lower end of the base 20, and the vehicle widthwise outer portion of the intermediate link portion 52B protrudes outward in the vehicle width direction from the opening 82. The base 20 is formed with insertion holes (not shown) through which the drive link 52 and the driven link 56 are inserted. The tip link portion 52C is adjacent to the vehicle widthwise inner side of the lid 40.

[0018] A link shaft 54 ​​is provided at the lower end of the tip-side link portion 52C (the tip end of the drive link 52). The link shaft 54 ​​is formed in a generally stepped cylindrical shape with its axial direction aligned in the front-rear direction, and has a small-diameter portion 54A in the axially intermediate portion. The link shaft 54 ​​rotates integrally with the drive link 52 around the base end of the drive link 52. In other words, the link shaft 54 ​​constitutes a part of the drive link 52. The link shaft 54 ​​is inserted into one end (the outer end in the vehicle width direction) of the connecting groove 42A of the lid 40. The link shaft 54 ​​is rotatably supported at one end of the connecting groove 42A and is configured to be movable in the longitudinal direction of the connecting groove 42A. In the following description, the state of the drive link 52 when the link shaft 54 ​​is positioned at one end of the connecting groove 42A is referred to as a locked, non-driven state.

[0019] The driven link 56 is formed in a generally long plate shape with its thickness direction in the front-to-rear direction and is formed in a generally crank shape when viewed from the rear. Specifically, the driven link 56 includes a base end link portion 56A extending in the up-down direction, an intermediate link portion 56B extending in a direction inclined downward as it extends from the lower end of the base end link portion 56A toward the outside in the vehicle width direction, and a tip end link portion 56C extending downward from the outer end of the intermediate link portion 56B in the vehicle width direction.

[0020] The driven link 56 is disposed above the drive link 52. An upper end of a base end link portion 56A of the driven link 56 (a base end portion of the driven link 56) is connected to the base 20 on the vehicle width inner side of the outer panel 80 so as to be rotatable with the longitudinal direction as the axial direction. That is, similar to the drive link 52, the base 20 extends to a position where it connects the upper end of the base end link portion 56A. Furthermore, the connection position of the base end of the driven link 56 to the base 20 in the vehicle width direction substantially coincides with the connection position of the base end of the drive link 52 to the base 20. The tip end link portion 56C is adjacent to the upper end portion of the lid 40 on the vehicle width inner side, and a lower end of the tip end link portion 56C (a tip end portion of the driven link 56) is connected to the driven link connecting portion 46 of the lid 40 so as to be rotatable with the longitudinal direction as the axial direction. Furthermore, the position at which the tip of the driven link 56 is connected to the lid 40 in the vehicle width direction substantially coincides with the position at which the tip of the drive link 52 is connected to the lid 40. As described above, the link mechanism 50 is configured as a so-called four-bar link, and when activated, the lid 40 moves between the open position and the closed position.

[0021] An actuator 60 serving as a drive unit is connected to the base end of the drive link 52. The actuator 60 is electrically connected to a control unit (not shown), and when the control unit drives the actuator 60, the drive link 52 rotates about the base end, thereby operating the link mechanism 50. More specifically, when the drive link 52 rotates in one direction (the direction of arrow A in FIGS. 1 and 2), the lid 40 moves from the open position to the closed position.

[0022] When the lid 40 is in a position other than the closed position, the connecting groove 42A extends in a direction intersecting the rotation direction of the link shaft 54 ​​in a rear view (see FIG. 2). As a result, when the lid 40 moves between the open position and the closed position, the drive link 52 rotates about the base end portion while maintaining a lock non-drive state.

[0023] On the other hand, when the lid 40 is in the closed position, the connecting groove 42A extends in the rotation direction of the link shaft 54 ​​in a rear view (see FIG. 4A). That is, the connecting groove 42A extends from the link shaft 54 ​​to one side in the rotation direction of the drive link 52. As a result, when the lid 40 is in the closed position, the connecting groove 42A allows the link shaft 54 ​​to move toward the other end of the connecting groove 42A. That is, when the lid 40 is in the closed position, the drive link connecting portion 42 connects the tip end of the drive link 52 to the lid 40 so as to allow the drive link 52 to rotate relative to the lid 40. Therefore, when the actuator 60 is driven, the drive link 52 rotates relative to the lid 40 toward one side in the rotation direction, and the link shaft 54 ​​is positioned at the other end (the inner end in the vehicle width direction) of the connecting groove 42A (this is the state shown in FIG. 4C; hereinafter, this state of the drive link 52 is referred to as the locked drive state). In addition, when the drive link 52 is in the locked drive state, the drive link 52 is rotated in the other rotation direction by driving the actuator 60, whereby the drive link 52 is switched to the locked non-drive state.

[0024] (Regarding the locking member 70) 2, the locking member 70 is formed in a generally V-shape that is open downward when viewed from the rear. Specifically, the locking member 70 includes a lock connecting portion 72 that extends in a direction that slopes outward in the vehicle width direction as it extends downward, and a locking portion 74 that extends from the upper end of the lock connecting portion 72 in a direction that slopes downward as it extends inward in the vehicle width direction.

[0025] The upper end of the lock connecting portion 72 is connected to the inner end of the lock support portion 44 of the lid 40 in the vehicle width direction so as to be rotatable with the longitudinal direction as the axial direction. This allows the locking member 70 to be rotatable on the lid 40. A slide groove 72A is formed in the lower end of the lock connecting portion 72 so as to penetrate in the longitudinal direction, and the slide groove 72A is formed as an elongated hole extending along the longitudinal direction of the lock connecting portion 72. The small diameter portion 54A of the link shaft 54 ​​described above is movably inserted into the slide groove 72A and is disposed at the lower end of the slide groove 72A. This allows the locking member 70 to be connected to the drive link 52. A hook portion 74A is formed at the tip of the locking portion 74, and the hook portion 74A protrudes upward from the locking portion 74.

[0026] When the lid 40 is in the closed position, the drive link 52 switches between a non-lock drive state and a lock drive state, causing the lock member 70 connected to the link shaft 54 ​​to rotate about the upper end of the lock connection portion 72. Specifically, the lock member 70 rotates between an unlock position (the position shown in FIGS. 2 and 4(A)) and a lock position (the position shown in FIG. 4(C)). When the lock member 70 is in the locked position, the link shaft 54 ​​is positioned at the upper end of the slide groove 72A.

[0027] Furthermore, as shown in FIG. 4(A), when the locking member 70 is in the unlocked position with the lid 40 in the closed position, the hook portion 74A is positioned below and spaced from the receiving recess 30A of the engagement receiving portion 30. Therefore, the locking member 70 and the engagement receiving portion 30 are not engaged with each other, and the locking member 70 is in an unlocked state (a state in which the lid 40 is permitted to move outward in the vehicle width direction). On the other hand, as shown in FIG. 4(C), when the lid 40 is in the closed position, the locking member 70 rotates from the unlocked position to the locked position, and the hook portion 74A is inserted into the receiving recess 30A of the engagement receiving portion 30. As a result, the locking member 70 and the engagement receiving portion 30 are engaged with each other in the vehicle width direction, and the locking member 70 is in a locked state (a state in which the lid 40 is prevented from moving outward in the vehicle width direction).

[0028] (Action and effect) Next, the effects of this embodiment will be described.

[0029] In the lid opening / closing device 10 configured as described above, when the lid 40 is in the open position, it is positioned on the outer side of the outer panel 80 of the vehicle in the vehicle width direction, and the opening 82 is opened outward in the vehicle width direction (see FIG. 1). In this state, the link shaft 54 ​​is positioned at one end of the connecting groove 42A of the lid 40, and the locking member 70 is positioned in the unlocked position. In addition, the connecting groove 42A extends in a direction intersecting the rotation direction of the link shaft 54 ​​in a rear view.

[0030] To move the lid 40 to the closed position, the actuator 60 rotates the drive link 52 in one direction of rotation, thereby operating the link mechanism 50. Specifically, as shown in Fig. 3(A), the drive link 52 rotates in one direction of rotation about its base end, and the driven link 56 rotates in one direction of rotation about its base end, so that the lid 40 is displaced from the open position outward and upward in the vehicle width direction while maintaining its plate thickness direction aligned with the vehicle width direction.

[0031] As shown in Figures 3(B) and 4(A), when the lid 40 reaches the closed position, the opening 82 is closed by the lid 40. In this state, the drive link 52 is maintained in a non-locked state, and the link shaft 54 ​​is positioned at one end of the connecting groove 42A. Also, the hook portion 74A of the locking member 70 is positioned below the receiving-side recess 30A of the engagement receiving portion 30, and the locking member 70 is maintained in an unlocked state. Furthermore, the connecting groove 42A extends along the rotation direction of the link shaft 54 ​​in a rear view, and rotation of the drive link 52 to one side in the rotation direction is permitted.

[0032] 4(B), the actuator 60 rotates the drive link 52 relative to the lid 40 in one rotation direction. As a result, the link shaft 54 ​​moves to the other end of the connecting groove 42A, and the locking member 70 connected to the link shaft 54 ​​rotates toward the locked position. That is, the locking member 70 operates in conjunction with the rotation of the drive link 52 relative to the lid 40.

[0033] As shown in FIG. 4(C), when the drive link 52 reaches the lock drive position, the locking member 70 is placed in the locked position. As a result, the hook portion 74A of the locking member 70 is inserted from below into the receiving recess 30A of the engagement receiving portion 30, and the locking member 70 and the engagement receiving portion 30 engage with each other in the vehicle width direction. Therefore, the locking member 70 is in a locked state, and the lid 40 is prevented from moving outward in the vehicle width direction. Even if the lid 40 is manually operated to the open side in this locked state, the link shaft 54 ​​of the drive link 52 remains positioned on the other end side of the connecting groove 42A, so the positional relationship between the lid 40 and the drive link 52 does not change. As a result, the locking member 70 is also maintained in the locked state, and the locking member 70 will not be disengaged from the engagement receiving portion 30.

[0034] As described above, in the lid opening / closing device 10, the engagement receiving portion 30 is provided on the base 20, and the locking member 70 is rotatably provided on the lid 40. Furthermore, the base end of the drive link 52 is rotatably connected to the base 20, and the tip end of the drive link 52 is connected to the drive link connecting portion 42 of the lid 40. When the lid 40 is in the open position, the actuator 60 rotates the drive link 52 in one rotation direction, causing the lid 40 to move to the closed position and close the opening 82. Here, the drive link connecting portion 42 connects the tip end of the drive link 52 to the lid 40 so as to allow the drive link 52 to rotate relative to the lid 40 when the lid 40 is in the closed position. Specifically, the link shaft 54 ​​of the drive link 52 is inserted into one end of the elongated connecting groove 42A of the drive link connecting portion 42, and the connecting groove 42A extends to allow the drive link 52 to rotate relative to the lid 40 in one direction. When the drive link 52 rotates relative to the lid 40 in one direction, the link shaft 54 ​​of the drive link 52 moves the locking member 70 from the unlocked position to the locked position and engages with the engagement receiving portion 30. That is, the locking member 70 switches from the unlocked state to the locked state. This allows the locking member 70 to be switched from the unlocked state to the locked state by utilizing the actuator 60 that drives the lid 40 to open and close. In other words, there is no need to provide a separate drive source for driving the locking member 70. This makes it possible to lock the lid 40 while suppressing cost increases.

[0035] As described above, the drive link connecting portion 42 of the lid 40 has an elongated connecting groove 42A, and the link shaft 54 ​​of the drive link 52 is movably inserted into the connecting groove 42A and is disposed at one end of the connecting groove 42A. When the lid 40 is in the closed position, the connecting groove 42A extends in the rotation direction of the link shaft 54 ​​in a rear view. That is, when the lid 40 is in the closed position, the connecting groove 42A extends so as to allow the link shaft 54 ​​to move from one end to the other end of the connecting groove 42A. This makes it possible to switch the drive link 52 between a lock non-drive state and a lock drive state while maintaining the lid 40 in the closed position.

[0036] Furthermore, when the lid 40 is in a position other than the closed position, the connecting groove 42A extends in a direction intersecting the rotation direction of the link shaft 54 ​​in a rear view. This allows the drive link 52 to rotate about its own base end while maintaining the locked, non-driven state of the drive link 52, thereby moving the lid 40 between the open position and the closed position.

[0037] The locking member 70 is rotatably connected to the lid 40 and includes a locking portion 74 configured to be engageable with the engagement receiving portion 30, and a locking connecting portion 72 connected to the link shaft 54. Specifically, the link shaft 54 ​​is movably inserted into a slide groove 72A of the locking connecting portion 72. When the drive link 52 is switched from a non-locking driven state to a locking driven state with the lid 40 in the closed position, the locking member 70 is rotated by the link shaft 54, and the hook portion 74A of the locking portion 74 is engaged with the receiving-side recess 30A of the engagement receiving portion 30 in the vehicle width direction. This allows the locking member 70 provided on the lid 40 to be engaged with the engagement receiving portion 30 with a simple configuration.

[0038] (Second embodiment) The lid opening and closing device 100 of the second embodiment will be described below with reference to Figures 5 to 7. The lid opening and closing device 100 of the second embodiment is configured similarly to the lid opening and closing device 10 of the first embodiment, except for the following points. In Figures 5 to 7, the same reference numerals are used to designate members that are configured similarly to the lid opening and closing device 10 of the first embodiment.

[0039] In the lid opening and closing device 100 of the second embodiment, an engagement pin 130 as an engagement receiving portion is provided on the base 20 instead of the engagement receiving portion 30. The engagement pin 130 is formed in a substantially cylindrical shape with its axial direction extending in the front-to-rear direction, and is provided on the lower part of the base 20.

[0040] Furthermore, in the lid opening / closing device 100, a locking member 170 is provided on the lid 40 instead of the locking member 70. The locking member 170 includes a locking portion 172 and a locking connecting portion 174. The locking portion 172 is formed in a generally U-shaped block shape that opens inward in the vehicle width direction when viewed from the rear. That is, the locking portion 172 has a locking recess 172A that opens inward in the vehicle width direction, and a bottom surface 172B of the locking recess 172A is formed in an arc shape. The width dimension of the locking recess 172A is set slightly larger than the diameter of the engagement pin 130. Furthermore, the locking portion 172 is rotatably connected to the drive link connecting portion 42 of the lid 40 by a locking connecting shaft 176 whose axial direction is the front-rear direction. The locking connecting shaft 176 is located below the longitudinal middle portion of the connecting groove 42A. The position of the lock connecting shaft 176 is set so that the axis of the lock connecting shaft 176 coincides with the center of the arc-shaped bottom surface 172B of the lock recess 172A when viewed from behind.

[0041] The lock connecting portion 174 protrudes outward in the vehicle width direction from an upper portion of the locking portion 172 in a rear view. A slide groove 174A extending substantially along the vehicle width direction is formed penetrating the lock connecting portion 174 in the front-rear direction. Specifically, the slide groove 174A extends in a direction that slopes upward as it extends outward in the vehicle width direction. The small diameter portion 54A of the link shaft 54 ​​of the drive link 52 is movably inserted into the slide groove 174A and is disposed within one end (the outer end in the vehicle width direction) of the slide groove 174A.

[0042] In the second embodiment, the lid 40 is also disposed on the outer side of the outer panel 80 of the vehicle in the open position, and the opening 82 is opened to the outer side in the vehicle width direction. The actuator 60 is driven to operate the link mechanism 50, and the lid 40 moves from the open position to the closed position.

[0043] As shown in FIG. 7A, when the lid 40 is in the closed position, the engagement pin 130 is inserted into the lock recess 172A of the lock member 170 from the inside in the vehicle width direction. In this state, the lock connecting shaft 176 of the lock member 170 is arranged coaxially with the engagement pin 130. Furthermore, in this state, the lock recess 172A is open toward the inside in the vehicle width direction, so that the lock member 170 is permitted to move toward the outside in the vehicle width direction relative to the engagement pin 130. Therefore, the lock member 170 is in an unlocked state. Furthermore, as in the first embodiment, the connecting groove 42A extends along the rotation direction of the link shaft 54 ​​in a rear view, so that the drive link 52 is permitted to switch from the lock non-drive state to the lock drive state.

[0044] 7(B), when the actuator 60 is driven to rotate the drive link 52 relative to the lid 40 in one rotation direction, the link shaft 54 ​​moves to the other end of the connecting groove 42A. At this time, the locking member 170 connected to the link shaft 54 ​​rotates to one side (clockwise as viewed from behind) around the axis of the lock connecting shaft 176 (engagement pin 130). In other words, the locking member 170 operates in conjunction with the rotation of the drive link 52 relative to the lid 40.

[0045] As shown in FIG. 7C, when the drive link 52 is switched to the locked drive state, the lock member 170 is positioned so that the lock recess 172A of the lock member 170 opens downward. This causes the lock member 170 to engage with the engagement pin 130 in the vehicle width direction. As a result, the lock member 170 is switched to the locked state, and the lid 40 is prevented from moving outward in the vehicle width direction. Even if the lid 40 is manually operated to the open side in this locked state, the link shaft 54 ​​of the drive link 52 remains positioned on the other end side of the connecting groove 42A, so the positional relationship between the lid 40 and the drive link 52 does not change. As a result, the lock member 170 is also maintained in the locked state, and the engagement between the lock member 170 and the engagement pin 130 will not be released.

[0046] As described above, in the second embodiment, as in the first embodiment, the locking member 170 can be rotated from the unlocked position to the locked position by utilizing the actuator 60 for driving the lid 40 to open and close. Therefore, in the second embodiment, the lid 40 can be locked while suppressing an increase in costs.

[0047] In the second embodiment, the locking member 170 includes a locking portion 172 having a locking recess 172A and a locking connecting portion 174 having an elongated slide groove 174A. When the lid 40 is in the closed position, the engaging pin 130 is inserted into the locking recess 172A, and the link shaft 54 ​​is inserted into the slide groove 174A so as to be relatively movable. When the lid 40 is in the closed position, the locking connecting shaft 176 of the locking member 170 and the engaging pin 130 are coaxially arranged. When the driving link 52 is switched from the non-locked driving state to the driven state, the locking member 70 rotates around the axis of the engaging pin 130, whereby the locking portion 172 engages with the engaging pin 130 in the vehicle width direction, and the locking member 170 is switched from the unlocked state to the locked state. As a result, similar to the first embodiment, the locking member 70 provided on the lid 40 can be engaged with the engagement receiving portion 30 with a simple configuration.

[0048] (Third embodiment) A lid opening and closing device 200 of the third embodiment will be described below with reference to Figures 8 to 10. The lid opening and closing device 200 of the third embodiment is configured similarly to the lid opening and closing device 10 of the first embodiment, except for the following points. In Figures 8 to 10, the same reference numerals are used to designate members that are configured similarly to the lid opening and closing device 10 of the first embodiment.

[0049] In a lid opening / closing device 200 of the third embodiment, a locking member 70 is provided at the bottom of the base 20. In the third embodiment, a locking connecting portion 72 of the locking member 70 extends in a direction that slopes outward in the vehicle width direction as it extends downward, and an upper end of the locking connecting portion 72 is connected to the base 20 so as to be rotatable about the front-to-rear direction as its axial direction. Furthermore, a locking portion 74 of the locking member 70 extends from the upper end of the locking connecting portion 72 in a direction that slopes upward as it extends outward in the vehicle width direction, and a hook portion 74A protrudes downward from the tip of the locking portion 74. This allows the locking member 70 to be connected to the base 20 so as to be rotatable between an unlocked position (the position shown in FIGS. 8 and 10(A)) and a locked position (the position shown in FIG. 10(C)). Furthermore, the locking member 70 is biased toward the unlocked position by a biasing member (not shown), and the locking member 70 is held in the unlocked position.

[0050] Furthermore, in the lid opening / closing device 200, the lock support portion 44 is omitted from the lid 40. An engagement receiving portion 30 is provided on the back surface of the lid 40 above the link shaft 54. In the third embodiment, the receiving-side recess 30A of the engagement receiving portion 30 is open upward. Furthermore, the link shaft 54 ​​of the drive link 52 has a pressing portion 54B, which is configured to be able to press the lock connecting portion 72 of the locking member 70.

[0051] In the third embodiment, the lid 40 is also disposed on the outer side of the outer panel 80 of the vehicle in the open position, and the opening 82 is opened to the outer side in the vehicle width direction. The actuator 60 is driven to operate the link mechanism 50, and the lid 40 moves from the open position to the closed position.

[0052] 10(A), when the lid 40 is in the closed position, the link shaft 54 ​​is disposed on the outer side in the vehicle width direction of the lower end of the lock connecting portion 72 of the locking member 70. Also, the receiving-side recess 30A of the engagement receiving portion 30 is disposed below the hook portion 74A of the locking member 70. Therefore, the unlocked state of the locking member 70 is maintained.

[0053] 10(B), when the lid 40 is in the closed position, the actuator 60 rotates the drive link 52 relative to the lid 40 in one rotation direction, causing the link shaft 54 ​​to move inward in the vehicle width direction. At this time, the pressing portion 54B of the link shaft 54 ​​presses the lock connecting portion 72 of the locking member 70 inward in the vehicle width direction, causing the locking member 70 to rotate clockwise as viewed from the rear. In other words, the locking member 70 operates in conjunction with the rotation of the drive link 52 relative to the lid 40.

[0054] 10(C), when the drive link 52 switches from the non-locked state to the locked state, the hook portion 74A of the locking member 70 is inserted from above into the receiving recess 30A of the engagement receiving portion 30, and the locking member 70 and the engagement receiving portion 30 engage with each other in the vehicle width direction. Therefore, the locking member 70 switches to the locked state, and the lid 40 is prevented from moving outward in the vehicle width direction.

[0055] As described above, in the third embodiment, as in the first embodiment, the locking member 70 can be rotated from the unlocked position to the locked position by utilizing the actuator 60 for driving the lid 40 to open and close. Therefore, in the third embodiment, the lid 40 can be locked while suppressing an increase in costs.

[0056] Moreover, in the third embodiment, the engagement receiving portion 30 is provided on the lid 40, and the locking member 70 is rotatably provided on the base 20. When the drive link 52 is switched from the non-lock driving state to the lock driving state with the lid 40 in the closed position, the pressing portion 54B of the drive link 52 presses the lock connecting portion 72, causing the locking member 70 to rotate, and the locking portion 74 of the locking member 70 to engage with the engagement receiving portion 30. This allows the locking member 70 provided on the base 20 to be rotated with a simple configuration and engaged with the engagement receiving portion 30 provided on the lid 40.

[0057] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
