Description

The present invention relates to a lid opening/closing structure applied to a lid body that closes an opening provided with, for example, a fuel supply port or a power supply port.

Conventionally, a lid opening/closing structure for opening/closing a fuel filler port of a vehicle body is known (for example, Patent Document 1). The lid opening/closing structure described in Patent Document 1 includes a lid and an opening/closing mechanism. The lid is a plate member that closes an opening that communicates with a fuel filler port of the vehicle body. The opening/closing mechanism has a first hinge member and a second hinge member connected in series with each other. One end of the first hinge member is rotatably supported by the vehicle body. The other end of the first hinge member is rotatably connected to one end of the second hinge member. The other end of the second hinge member is rotatably supported by the lid. The first hinge member and the second hinge member are folded so as to be accommodated in the opening when the lid is closed, and when the lid is open, the two are opened so as to be aligned in a straight line while extending inward and outward from the vehicle body. Jumps out from the car body. According to this structure, since the opening/closing locus of the lid can be moved away from the vehicle body, the lid can be opened/closed without interfering with the vehicle body.

However, as described above, in the structure in which the two hinge members are respectively folded so that the opening/closing locus of the lid moves away from the vehicle body, and the two hinge members are linearly aligned in the inner and outer directions of the vehicle body, both hinge members are respectively moved. Since it rotates, the opening/closing mechanism is complicated. Further, in this structure, since the pivoting angle of each of the hinge members is large between the closed state and the open state of the lid body, there is a possibility that the smooth opening/closing operation of the lid body may be hindered.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a lid opening/closing structure capable of easily realizing a smooth opening/closing operation of a lid while preventing interference with the vehicle body. And

One aspect of the present invention is a lid opening/closing structure including a lid body that closes an opening provided in a vehicle body, and an opening/closing mechanism that opens and closes the lid body, wherein the opening/closing mechanism is provided inside the opening. Is formed so as to extend inward and outward from the vehicle body, is rotatably supported by the lid body at the outer end portion of the vehicle body through the first rotation shaft, and is movable inward and outward from the vehicle body side. Sliding member, and a hinge rotatably supported at one end by the lid through the second rotation shaft and at the other end rotatably supported by the vehicle body through the third rotation shaft. A member, and the first rotation shaft is on an outer movement side with respect to the second rotation shaft, the position of the axis of which moves toward the outside of the vehicle body during the opening operation on the back surface of the lid body. And the third rotation shaft is positioned in the orthogonal direction orthogonal to the moving direction of the slide member with respect to the second rotation shaft in the closed state of the lid body. Is a lid opening/closing structure that is arranged so as to be on the outward movement side of the lid body.

With this configuration, the lid body can be opened so that the center of rotation with respect to the vehicle body side moves in the vehicle exterior direction away from the vehicle body side. Therefore, it is possible to prevent the lid body from interfering with the vehicle body side when the lid body is opened. Further, the opening operation of the lid body can be realized by the slide member slidingly moving in the vehicle body outside direction with respect to the vehicle body side and the hinge member rotating at both the inside and outside ends of the vehicle body. Therefore, when the lid body is opened, the center of rotation with respect to the vehicle body can be moved in the outward direction of the vehicle body with a simple structure without a complicated configuration. Further, the respective turning angles of the lid body and the hinge member between the closed state and the opened state of the lid body can be suppressed to be small. Therefore, the opening/closing operation of the lid can be smoothly realized. Therefore, the smooth opening/closing operation of the lid can be easily realized while preventing the interference with the vehicle body.

The shaft holes 42 of the two protruding portions 41 are formed so as to be aligned with each other. A common third pin 83 is inserted into the shaft holes 42 of the two protruding portions 41. The third pin 83 is a columnar shaft body formed in a straight rod shape. The third pin 83 extends parallel to the surface of the bottom wall portion 13.

The slide member 50 is a member that can slide in the vehicle interior inward/outward direction X with respect to the fixed member 40 and thus the vehicle body panel 10. The slide member 50 is formed in a box shape so as to cover the outer surface of the fixed member 40. The slide member 50 extends in the vehicle body inside/outside direction X of the vehicle body panel 10, and more specifically, in a direction perpendicular to the front surface of the bottom wall portion 13 of the vehicle body panel 10 and the back surface of the lid body 20 in the closed state. Extends to. The slide member 50 is arranged inside the opening 11 of the vehicle body panel 10.

The slide member 50 has an insertion hole 51 that is opened at the vehicle body outer end surface of the box-shaped portion, and a projecting portion 52 that projects in the vehicle body outer direction X+ from the vehicle body outer end surface of the box-shaped portion. The insertion hole 51 is a hole through which the protruding portion 41 of the fixing member 40 projects from the vehicle body inner direction X− side to the vehicle body outer direction X+ side. The protrusions 52 are provided at two locations, and are arranged side by side along the surface of the bottom wall portion 13 and along the surface of the side wall portion 12.

A shaft hole 53 is provided at an outer end of the vehicle body of each protrusion 52. The shaft hole 53 is a circular hole extending in parallel along the surface of the bottom wall portion 13 and the back surface of the lid body 20. The shaft holes 53 of the two protruding portions 52 are formed so as to be aligned with each other. The first pin 81 described above is inserted into the shaft holes 53 of the two protruding portions 52. The slide member 50 is rotatably supported by the lid body 20 via a first pin 81 that is inserted into both the axial hole 53 of the vehicle body outer end portion and the axial hole 23 of the lid body 20. The first pin 81 constitutes a first rotation axis A1 that relatively rotates the slide member 50 and the lid 20.

The fixing member 40 has a spring support portion 43. The spring support portion 43 is a portion that supports one end of the biasing member 60. The slide member 50 has a spring support portion 54. The spring support portion 54 is a portion that supports the other end portion of the biasing member 60. The spring support portion 54 abuts on a restriction portion (specifically, the bottom wall portion 13 at the peripheral edge of the hole 16) provided on the vehicle body panel 10 and predetermined slide movement of the slide member 50 in the vehicle exterior direction X+. It has the following functions.

The biasing member 60 is interposed between the fixed member 40 (specifically, the spring support portion 43) and the slide member 50 (specifically, the spring support portion 54). The biasing member 60 is arranged below the bottom wall portion 13 of the vehicle body panel 10. The biasing member 60 is a coil spring that generates a biasing force that biases the slide member 50 in the vehicle exterior direction X+ with respect to the fixed member 40. The urging force of the urging member 60 causes the lid body 20 to be opened when the claw portion 21 of the lid body 20 and the stopper portion 15 on the vehicle body panel 10 side are released when the lid body 20 is closed. helpful. The slide member 50 slides in the vehicle exterior direction X+, which corresponds to the extending direction of the slide member 50 (that is, the direction perpendicular to the back surface of the lid body 20 in the closed state) by the urging force of the urging member 60. To do.

The hinge member 70 is a member that can swing (rotate) with respect to the lid body 20 and swing (rotate) with respect to the vehicle body panel 10. The hinge member 70 is formed in a plate shape. The hinge member 70 is provided with two shaft holes 71 and 72. The shaft hole 71 is provided at the vehicle body outer end portion of the hinge member 70. The shaft hole 72 is provided at the inner end of the hinge member 70 in the vehicle body.

The shaft hole 71 is a circular hole extending in parallel along the surface of the bottom wall portion 13 and the back surface of the lid body 20. The second pin 82 is inserted into the shaft hole 71. The hinge member 70 is rotatably supported by the lid 20 via a second pin 82 that is inserted into both the axial hole 71 at the outer end of the vehicle body and the axial hole 24 of the lid 20. The second pin 82 constitutes a second rotation axis A2 that relatively rotates the hinge member 70 and the lid 20.

The shaft hole 72 is a circular hole that extends in parallel along the surface of the bottom wall portion 13 and the back surface of the lid body 20. The third pin 83 is inserted into the shaft hole 72. The hinge member 70 is rotatably supported by the fixing member 40 and thus the vehicle body panel 10 via a third pin 83 that is inserted into both the shaft hole 72 at the inner end of the vehicle body and the shaft hole 42 of the fixing member 40. Has been done. The third pin 83 constitutes a third rotation axis A3 that relatively rotates the hinge member 70 and the vehicle body panel 10.

Two rotation axes A3, A1 among the three rotation axes A1, A2, A3 (that is, a shaft hole 42 provided in the fixing member 40 of the vehicle body panel 10 and a shaft provided in the convex portion 22 of the lid 20). The holes 23, and by extension, the two pins 83, 81 inserted into the shaft holes 42, 23) are arranged so that the following positional relationship is established. Specifically, the third rotation axis A3 formed by the third pin 83 has an axial center position on the X- side in the vehicle body direction with respect to the first rotation axis A1 formed by the first pin 81. In addition, the axial center of the hinge member 70 is arranged so that the position in the orthogonal direction orthogonal to the moving direction of the slide member 50 in the plane in which the hinge member 70 rotates is substantially coincident.

Two of the three rotation shafts A1, A2, A3, that is, two rotation shafts A1, A2 (that is, two shaft holes 23, 24 provided in the convex portion 22 of the lid 20 and, by extension, those shaft holes 23). The two pins 81 and 82 which are inserted into the connector 24 are arranged so that the following arrangement positional relationship is established. Specifically, the first rotation axis A1 formed by the first pin 81 is in a closed state on the back surface of the lid body 20 with respect to the second rotation axis A2 formed by the second pin 82. Is arranged so as to be the side that moves in the vehicle exterior direction X+ (that is, the outward movement side) during the opening operation from the to the open state.

Further, two rotation axes A2, A3 among the above-mentioned three rotation axes A1, A2, A3 (that is, provided in the shaft hole 24 provided in the convex portion 22 of the lid 20 and the fixing member 40 of the vehicle body panel 10). The shaft holes 42, and by extension, the pins 82, 83 inserted into the shaft holes 24, 42) are arranged so that the following positional relationship is established. Specifically, the third rotation axis A3 formed by the third pin 83 is a hinge that is an axial center with respect to the second rotation axis A2 formed by the second pin 82 when the lid 20 is closed. The position in the orthogonal direction orthogonal to the moving direction of the slide member 50 in the plane in which the member 70 rotates is arranged so as to be the outward moving side of the lid body 20. The timing at which the third rotation axis A3 is arranged such that its axial center position is on the outward movement side of the lid body with respect to the second rotation axis A2 is not limited to the closed state of the lid body 20. It is preferable to continue between the closed state and the open state of the lid body 20.

Next, the operation of the lid opening/closing structure 1 will be described.

The lid body 20 is locked in the closed state by the hook portion 21 of the lid body 20 being caught by the stopper portion 15 on the vehicle body panel 10 side. In such a closed state, the hinge member 70 of the opening/closing mechanism 30 is in a direction different from the vehicle body inside/outside direction X, which is the moving direction of the slide member 50, and more specifically, with respect to the vehicle body inside/outside direction X. From the inside of the vehicle body that is connected to the fixing member 40 of the panel 10 to the outside of the vehicle body that is connected to the lid body 20, the side that moves in the in-vehicle direction X- when the lid body 20 is opened from the closed state to the open state. (I.e., the inward moving side) extends in a direction inclined (FIGS. 3, 4, and 5).

When the vehicle occupant performs a predetermined opening operation to open the lid body 20 in the closed state of the lid body 20, the catching of the claw portion 21 by the stopper portion 15 is released. When this catch is released, the urging force of the urging member 60 acts on the slide member 50, so that the slide member 50 extends in the vehicle body outward direction X+ in which the slide member 50 extends with respect to the fixed member 40 and thus the vehicle body panel 10. Slide to move. When the slide member 50 slides in the vehicle body outward direction X+ with respect to the vehicle body panel 10, the first pin 81 (that is, the first rotation shaft) inserted into the shaft hole 53 of the slide member 50 and the shaft hole 23 of the lid 20. A1) rotates in the opening direction with respect to the second pin 82 (that is, the second rotation axis A2) in which the lid body 20 is inserted into the shaft hole 24 of the lid body 20 and the shaft hole 71 of the hinge member 70. The vehicle moves in the direction (specifically, the vehicle exterior direction X+).

When the movement of the first pin 81 in the vehicle exterior direction X+ occurs, the first pin 81 (that is, the first rotation axis A1), the shaft hole 72 of the hinge member 70, and the vehicle body panel follow the movement. The distance between the axes of the third pin 83 (that is, the third rotation axis A3) that is inserted into the shaft hole 42 of the fixing member 40 of No. 10 increases. When this separation distance increases, the lid body 20 rotates in the opening direction about the second pin 82 (that is, the second rotation axis A2) according to the separation distance, and the second rotation axis A2 moves. The axial center position moves to the center side of the opening 11 (that is, the outward movement side of the lid body 20) with respect to the vehicle body panel 10, and the hinge member 70 causes the third pin 83 (that is, the third rotation axis A3). Rotate around. As a result, the lid 20 opens so as to open the opening 11 of the vehicle body panel 10.

Then, when the spring support portion 54 of the slide member 50 comes into contact with the regulation portion of the vehicle body panel 10, the rotation of the lid body 20 about the second rotation axis A2 is stopped, and the opening operation of the lid body 20 is stopped. To be done. In this case, the distance between the axes of the third pin 83 and the first pin 81 becomes maximum, and the lid 20 is opened. In this open state, the inclination angle of the hinge member 70 with respect to the vehicle interior-external direction X is minimized, and the axial center position of the second rotation axis A2 is furthest away from the bottom wall portion 13 of the vehicle body panel 10 in the vehicle exterior direction X+ (FIG. 6, FIG. 7, and FIG. 8).

In the lid opening/closing structure 1, as shown in FIG. 9, in the process of opening the lid 20 from the closed state to the open state, the inclination angle of the hinge member 70 with respect to the moving direction of the slide member 50, that is, the vehicle interior/exterior direction X is changed. Since it gradually becomes smaller, the axial center position of the second rotation axis A2 moves away from the side closer to the bottom wall portion 13 of the vehicle body panel 10 in the vehicle exterior direction X+. The second rotation axis A2 is a rotation center around which the lid 20 rotates with respect to the vehicle body panel 10 side (specifically, the hinge member 70). In this structure, the opening operation of the lid body 20 is performed so that the center of rotation of the lid body 20 with respect to the hinge member 70 moves in the vehicle exterior direction X+ which is separated from the bottom wall portion 13 of the vehicle body panel 10. That is, the entire lid 20 moves in the vehicle exterior direction X+ during the opening operation. Therefore, it is possible to prevent the lid body 20 from interfering with the vehicle body panel 10 during the opening operation of the lid body 20.

The opening/closing mechanism 30 is interposed between the slide member 50 that slides in the vehicle body inward/outward direction X with respect to the vehicle body panel 10 and the hinge that is rotatably supported by both of the vehicle body panel 10 and the lid 20. And a member 70. In the opening/closing mechanism 30, as the slide member 50 slides, one hinge member 70 rotates with respect to the vehicle body panel 10 about the third rotation axis A3 and the second hinge member 70 with respect to the lid body 20. The lid 20 opens and closes while rotating about the rotation axis A2. That is, when the lid 20 is opened/closed, the slide member 50 may slide in the vehicle body inner/outer direction X with respect to the vehicle body panel 10, and the hinge member 70 may rotate at both inner/outer ends of the vehicle body. According to the opening/closing mechanism 30, it is easy to move the rotation center (specifically, the second rotation axis A2) in the vehicle body outward direction X+ during the opening operation of the lid body 20 without a complicated configuration. Can be realized with a simple structure.

In the opening/closing mechanism 30, the rotation angle about the third rotation axis A3 between the hinge member 70 and the vehicle body panel 10 between the closed state and the opened state of the lid body 20, and the vehicle body panel. The rotation angles around the first rotation axis A1 between the 10 side (specifically, the slide member 50) and the lid body 20 are less than 90°, respectively, and the lid body 20 and the hinge member 70 are separated from each other. The rotation angle around the second rotation axis A2 is less than 180°. In this case, each rotation angle of the lid 20 between the closed state and the open state is suppressed to be small. Therefore, it is possible to realize a smooth opening/closing operation of the lid body 20 as compared with an opening/closing mechanism having a relatively large rotation angle.

Further, in the opening/closing mechanism 30, the biasing member 60 that generates a biasing force for sliding the slide member 50 relative to the vehicle body panel 10 is arranged below the bottom wall portion 13 of the vehicle body panel 10. For this reason, it is possible to prevent the biasing member 60 from being exposed to dust, dust, rain, etc. when the lid 20 is in the open state, and thus it is possible to prevent the malfunction of the biasing member 60 from occurring. The smooth opening/closing operation of the lid 20 can be maintained for a long period of time.

Therefore, according to the lid opening/closing structure 1, the smooth opening/closing operation of the lid 20 can be easily realized while preventing the interference with the vehicle body panel 10.

The biasing member 60 of the opening/closing mechanism 30 is a coil spring that generates a biasing force that biases the slide member 50 in the vehicle exterior direction X+ with respect to the fixed member 40. In this structure, the biasing force generated by the biasing member 60 becomes smaller as the opening operation of the lid 20 progresses, so that the opening speed of the lid 20 during the opening operation can be gradually reduced. Therefore, it is possible to reduce the force when the spring support portion 54 of the slide member 50 comes into contact with the regulation portion of the vehicle body panel 10, and it is possible to suppress damage to parts and contact sound that accompany the contact.

Further, the opening operation of the lid 20 is performed until the spring support portion 54 of the slide member 50 abuts on the regulation portion of the vehicle body panel 10, and the spring support portion 54 of the slide member 50 abuts on the regulation portion of the vehicle body panel 10. If you do, it will be stopped. Therefore, the opening of the lid 20 beyond a predetermined opening can be restricted.

In the above first embodiment, the vehicle body panel 10 is on the “vehicle body” described in the claims, and the vehicle body panel 10 and the fixing member 40 are on the “vehicle body side” described in the claims. The first rotation axis A1 formed by the pin 81 is the "first rotation axis" described in the claims, and the second rotation axis A2 formed by the second pin 82 is described in the claims. In the "second rotating shaft", the third rotating shaft A3 formed by the third pin 83 is described in the claims, and in the "third rotating shaft", the first pin 81 is described in the claims.

[Second embodiment]
In the lid opening/closing structure 1 of the above-described first embodiment, the slide member 50 extends in the vehicle body inside/outside direction X that is perpendicular to the back surface of the lid body 20 in the closed state. The biasing member 60 is a coil spring that generates a biasing force between the fixed member 40 and the slide member 50 that biases the slide member 50 toward the fixed member 40 in the vehicle body outward direction X+. Therefore, the slide member 50 slides in the direction perpendicular to the back surface of the lid body 20 in the closed state, that is, in the vehicle body outward direction X+ in which the slide member 50 extends by the biasing force of the biasing member 60. Moving.

On the other hand, the lid opening/closing structure 100 of this embodiment includes an opening/closing mechanism 110 instead of the opening/closing mechanism 30 of the lid opening/closing structure 1 of the first embodiment, as shown in FIGS. 10, 11, and 12. ing. In the following description, in the lid opening/closing structure 100, the same components as those of the lid opening/closing structure 1 are designated by the same reference numerals, and the description thereof will be omitted or simplified.

In the opening/closing mechanism 110, the slide member 50 extends in a direction inclined with respect to the vehicle body inside/outside direction X which is perpendicular to the back surface of the lid body 20 in the closed state. Further, the fixing member 40 also extends in a direction similarly inclined with respect to the vehicle interior-external direction X. The direction inclining with respect to the vehicle body inward/outward direction X is a direction inclining toward the inward moving side that moves in the vehicle body inward direction X− when the lid 20 is opened from the vehicle body inward side to the vehicle outward side. Is. The biasing member 60 is a coil spring that generates a biasing force between the fixing member 40 and the sliding member 50 that biases the sliding member 50 in an oblique direction with respect to the fixing member 40 with respect to the vehicle exterior direction X+. Then, the slide member 50 is inclined by the urging force of the urging member 60 with respect to the vehicle body panel 10 with respect to the vehicle body outer direction X+ perpendicular to the back surface of the lid body 20 in the closed state (specifically, , The same direction as the direction in which the slide member 50 extends from the inner side of the vehicle body to the outer side of the vehicle body, the direction being inclined toward the inward moving side that moves in the vehicle body inward direction X− when the lid 20 is opened. Slide direction).

In the opening/closing mechanism 110 as well, the third rotation axis A3 formed by the third pin 83 is located on the X- side in the vehicle body inward direction with respect to the first rotation axis A1 formed by the first pin 81. They are arranged in such a manner that their axial centers substantially coincide with each other in the orthogonal direction orthogonal to the moving direction of the slide member 50 within the plane in which the hinge member 70 rotates. The first rotation axis A1 has an axial center position relative to the second rotation axis A2 formed by the second pin 82 in the vehicle exterior direction X+ during the opening operation on the back surface of the lid 20 from the closed state to the open state. Is arranged to be the side moving to (ie, the outward moving side). Further, the third rotation axis A3 is orthogonal to the moving direction of the slide member 50 within the plane in which the hinge member 70 rotates about the axis with respect to the second rotation axis A2 in the closed state of the lid body 20. Is arranged so that the position in the orthogonal direction is on the outward moving side of the lid 20.

In the lid opening/closing structure 100, the inclination angle of the hinge member 70 with respect to the moving direction of the slide member 50 gradually decreases in the process of opening the lid body 20 from the closed state to the open state. Moves from the side closer to the bottom wall portion 13 of the vehicle body panel 10 to the side farther from the bottom wall portion 13 of the vehicle body panel 10 (that is, the moving direction of the slide member 50 in the vehicle body outward direction X+). The second rotation axis A2 is a rotation center around which the lid 20 rotates with respect to the vehicle body panel 10 side (specifically, the hinge member 70). In this case, the opening operation of the lid body 20 is performed so that the center of rotation of the lid body 20 moves toward the vehicle exterior direction X+ side away from the bottom wall portion 13 of the vehicle body panel 10. That is, the entire lid body 20 moves toward the vehicle exterior outward direction X+ side during the opening operation. Therefore, it is possible to prevent the lid body 20 from interfering with the vehicle body panel 10 during the opening operation of the lid body 20. Further, also in the lid opening/closing structure 100, the same effect as that of the lid opening/closing structure 1 described above can be obtained. Therefore, also in the lid opening/closing structure 100, the smooth opening/closing operation of the lid 20 can be easily realized while preventing the interference with the vehicle body panel 10.

The direction inclining with respect to the vehicle body inward/outward direction X is a direction inclining toward the inward moving side that moves in the vehicle body inward direction X− when the lid 20 is opened from the vehicle body inward side to the vehicle outward side. Is. In this structure, since the lid body 20 can be tilted with respect to the vehicle body panel 10 to the direction in which the slide member 50 is tilted, the opening operation of the lid body 20 can be performed to a large opening, and the lid body 20 can be opened and closed. The angle range can be expanded.

[Third embodiment]
In the lid opening/closing structure 100 of the second embodiment, the slide member 50 extends in a direction inclined with respect to the vehicle body inside/outside direction X that is perpendicular to the back surface of the lid body 20 in the closed state. The biasing member 60 is a coil spring that generates a biasing force between the fixing member 40 and the sliding member 50 that biases the sliding member 50 in an oblique direction with respect to the fixing member 40 with respect to the vehicle exterior direction X+. For this reason, the slide member 50 slides in the direction inclined with respect to the vehicle body panel 10 by the urging force of the urging member 60 with respect to the vehicle body outside direction X+ which is perpendicular to the back surface of the lid body 20 in the closed state. ..

In contrast, the lid opening/closing structure of the present embodiment includes an opening/closing mechanism 210 instead of the opening/closing mechanism 30 of the lid opening/closing structure 1 of the first embodiment, as shown in FIG. 13. In the lid opening/closing structure, the same components as those of the lid opening/closing structure 1 are designated by the same reference numerals, and the description thereof will be omitted or simplified.

In the opening/closing mechanism 210, the slide member 50 has a portion (specifically, the protruding portion 52) extending from the main body portion in a direction inclined with respect to the vehicle body inside/outside direction X that is perpendicular to the back surface of the lid body 20 in the closed state. is doing. The direction inclining with respect to the vehicle body inward/outward direction X is a direction inclining toward the inward moving side that moves in the vehicle body inward direction X− when the lid 20 is opened from the vehicle body inward side to the vehicle outward side. Is. The biasing member 60 is a coil spring that generates a biasing force between the fixed member 40 and the slide member 50 that biases the slide member 50 toward the fixed member 40 in the vehicle body outward direction X+. The slide member 50 is in a closed state, which is different from the extending direction of the portion of the slide member 50 inclined with respect to the vehicle body inside/outside direction X with respect to the vehicle body panel 10 due to the urging force of the urging member 60. And slides in the vehicle body outward direction X+ which is perpendicular to the back surface of the lid body 20.

In this opening/closing mechanism 210, the third rotation axis A3 formed by the third pin 83 is located on the X- side in the vehicle body inward direction with respect to the first rotation axis A1 formed by the first pin 81. The position of the shaft center in the orthogonal direction orthogonal to the moving direction of the slide member 50 in the plane in which the hinge member 70 is rotated is in the vehicle exterior direction X+ when the lid 20 is opened. It is arranged so that it is the outward moving side that moves. The first rotation axis A1 has an axial center position relative to the second rotation axis A2 formed by the second pin 82 in the vehicle exterior direction X+ during the opening operation on the back surface of the lid 20 from the closed state to the open state. It is arranged so that it is the outward moving side that moves to. Further, the third rotation axis A3 is orthogonal to the moving direction of the slide member 50 within the plane in which the hinge member 70 rotates about the axis with respect to the second rotation axis A2 in the closed state of the lid body 20. Is arranged so that the position in the orthogonal direction is on the outward moving side of the lid 20.

In this lid opening/closing structure, as shown in FIG. 13, in the process of opening the lid body 20 from the closed state to the open state, the inclination angle of the hinge member 70 with respect to the moving direction of the slide member 50 is gradually reduced. From the side where the axial center position of the two rotation axes A2 is close to the bottom wall portion 13 of the vehicle body panel 10 to the side far from the bottom wall portion 13 of the vehicle body panel 10 (that is, the movement direction of the slide member 50 in the vehicle body outward direction X+). Moving. The second rotation axis A2 is a rotation center around which the lid 20 rotates with respect to the vehicle body panel 10 side (specifically, the hinge member 70). In this case, the opening operation of the lid body 20 is performed so that the center of rotation of the lid body 20 moves toward the vehicle exterior direction X+ side away from the bottom wall portion 13 of the vehicle body panel 10. That is, the entire lid body 20 moves toward the vehicle exterior outward direction X+ side during the opening operation. Therefore, it is possible to prevent the lid body 20 from interfering with the vehicle body panel 10 during the opening operation of the lid body 20. Also, with this lid opening/closing structure, the same effect as that of the lid opening/closing structure 1 can be obtained. Therefore, also in the lid opening/closing structure of the third embodiment, the smooth opening/closing operation of the lid 20 can be easily realized while preventing the interference with the vehicle body panel 10.

In the opening/closing mechanism 210, the slide member 50 slides in the vehicle body outward direction X+ perpendicular to the back surface of the lid body 20 in the closed state with respect to the vehicle body panel 10 by the urging force of the urging member 60. The slide member 50 has a portion extending at an outer end portion of the vehicle body in a direction inclined with respect to a vehicle body inward/outward direction X which is perpendicular to the back surface of the lid body 20 in the closed state. The direction inclining with respect to the vehicle body inward/outward direction X is a direction inclining toward the inward moving side that moves in the vehicle body inward direction X− when the lid 20 is opened from the vehicle body inward side to the vehicle outward side. Is. In this structure, when the lid 20 is opened, the angle of inclination of the hinge member 70 with respect to the moving direction of the slide member 50 is changed from a large angle to a small angle corresponding to the angle at which the above-mentioned inclined portion of the slide member 50 is inclined. Since it can be tilted, the opening operation of the lid body 20 can be performed to a large opening degree, and the angular range of opening and closing of the lid body 20 can be further widened.

By the way, in the above-mentioned first and second embodiments, the pins 81 and 82 inserted into the two shaft holes 23 and 24 provided in the lid body 20 are both formed in a cylindrical shape, and the two shaft holes 23 and 24 are 24 are both formed in a circular shape. However, the present invention is not limited to this. For example, as shown in FIG. 13 of the third embodiment, at least one of the two shaft holes 23 and 24 of the lid 20 through which the cylindrical pins 81 and 82 are inserted is parallel to the back surface of the lid 20. It may be a long hole extending in any direction longer than the shaft diameter of the pins 81, 82.

In the structure of this modification, since the pins 81 and 82 can be moved within the long shaft holes 23 and 24 when the lid 20 is opened and closed, the lid 20 can be smoothly opened and closed. You can Further, compared to the structure shown in the first embodiment in which the shaft holes 23 and 24 are circular holes, when the slide member 50 slides with respect to the vehicle body panel 10 in the outer direction +X of the vehicle body by the same amount, the lid body is moved. Since the opening degree based on the closed state of 20 can be increased, the lid 20 can be opened and closed in a wider angle range.

In the first, second, and third embodiments described above, the opening/closing mechanisms 30, 110, 210 include the biasing member 60 interposed between the fixed member 40 and the slide member 50, and the lid body. 20 is kept closed with respect to the vehicle body panel 10 by engaging its claw portion 21 with the stopper portion 15 of the vehicle body panel 10, and the lid 20 is biased by the biasing member 60 by a predetermined opening operation of the vehicle occupant. It is assumed that the opening operation is performed on the vehicle body panel 10 by the urging force of. However, the present invention is not limited to this. The opening/closing mechanisms 30, 110, 210 may not be provided with the above-mentioned urging member, and may be applied to one in which the vehicle occupant manually opens the lid 20 with respect to the vehicle body panel 10.

Further, in the above-described first, second, and third embodiments, the member on which the hinge member 70 of the opening/closing mechanism 30 is rotatably supported about the third rotation axis A3 is provided on the vehicle body panel 10. The fixing member 40 is attached and fixed. However, the present invention is not limited to this.
