Description

[Technical field]

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

[0002] Conventionally, there has been a lid device for opening and closing a fuel filler port or a power filler port of a vehicle such as an automobile that includes a housing attached to the fuel filler port and a lid that opens and closes an opening of the housing (see, for example, Patent Document 1).

[0003] Such a lid device generally includes a biasing member such as a spring, which biases the lid in a direction to open it. When the fuel filler or power filler is closed, the lid is locked to the housing, but when an operator unlocks the lid, the biasing force of the biasing member opens the lid. However, if the biasing force of the biasing member is too strong, the lid may open forcefully, which may reduce the durability of the lid itself and the lid opening / closing mechanism. For this reason, methods have been proposed for conventional opening / closing structures that make the lid opening and closing action (especially the opening) more gradual. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] European Patent Application Publication No. 000887218 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, in conventional devices, oil dampers have been used to make the opening and closing action of the lid (especially the opening) smoother. However, oil dampers are expensive and are therefore undesirable from a cost perspective. On the other hand, some conventional devices have proposed structures that suppress the momentum of the lid when it opens without using an oil damper, but all of these structures are complex and there is room for improvement.

[0006] The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a lid device that has a simple structure and is capable of suppressing the momentum generated when the lid is opened. [Means for solving the problem]

[0007] In order to achieve the above object, the lid device according to the present invention has the following features (1) to (4).

[0008] (1) A lid device that is attached to a fuel filler port or a power filler port of a vehicle and opens and closes the fuel filler port or the power filler port, A housing assembled to the fuel supply port or the power supply port; a shaft member journalled to the housing; a lid rotatably supported by the shaft member and displaceable between a closed position and an open position; Equipped with The shaft member is provided with an extension piece extending in a direction intersecting with the axial direction, The housing is provided with a sliding contact portion with which the extension piece slides when the lid moves from the closed position to the open position. It is a lid device.

[0009] According to the above configuration (1), when the lid is displaced from the closed position to the open position, the extension piece provided on the shaft member slides against the sliding contact portion provided on the housing. That is, when the lid is opened, the extension piece slides against the sliding contact portion, generating friction between the extension piece and the sliding contact portion. As a result, the above configuration can suppress the momentum of the lid opening with a simple structure.

[0010] (2) The lid device according to (1) above, The extension piece is provided in a cantilever shape, The sliding contact portion has an inclined surface formed in an inclined manner such that a sliding contact intermediate position with the extension piece is located closer to the extension piece in the axial direction than a sliding contact start position. It is a lid device.

[0011] According to the above configuration (2), the sliding portion has an inclined surface formed in an inclined manner such that the midpoint of sliding contact with the extension piece is located closer to the extension piece in the axial direction than the start point of sliding contact, and the extension piece is provided in a cantilever shape. As a result, from the start stage of sliding contact of the extension piece with the inclined surface to the midpoint of sliding contact, the extension piece slides up the inclined surface while elastically deforming, so that the friction generated between the extension piece and the inclined surface gradually increases as the lid approaches the open position. That is, the force of the lid opening can be gradually reduced while suppressing the load on the lid device when the lid is opened. In addition, the force of the lid opening can be adjusted by changing the inclination angle of the inclined surface, since the magnitude of the friction generated between the extension piece and the inclined surface changes.

[0012] (3) The lid device according to (1) or (2), A protruding portion is provided at an extension end of the extension piece, protruding toward the sliding contact portion in the axial direction and having a protruding end surface that is in sliding contact with the sliding contact portion. It is a lid device.

[0013] According to the above configuration (3), the extending end of the extending piece is provided with a protruding portion whose protruding end surface is in sliding contact with the sliding contact portion. By changing the area of ​​the protruding end surface, the magnitude of friction generated between the protruding end surface and the sliding contact portion can be changed, so that the momentum when the lid is opened can be adjusted.

[0014] (4) The lid device according to (3) above, The protruding end surface is formed in an inclined shape so as to be in surface contact with the inclined surface. It is a lid device.

[0015] According to the above configuration (4), the protruding end face is formed in an inclined shape so as to be in surface contact with the inclined surface, so that the protruding end face and the inclined surface better engage with each other when they slide against each other, thereby more appropriately suppressing the momentum when the lid is opened. Effect of the Invention

[0016] According to the present invention, it is possible to provide a lid device that has a simple structure and is capable of suppressing the momentum when the lid is opened.

[0024] 2 and 3, the lid device 1 includes a housing 10, a lid 20, an axis member 50, and an urging member 60. The housing 10, the lid 20, the axis member 50, and the urging member 60 that constitute the lid device 1 will be described below in order.

[0025] First, the housing 10 will be described. The housing 10 is fitted and assembled into a recessed mounting portion (not shown) formed on the vehicle body, such as the rear fender 2 of the vehicle. As shown in Figures 3 and 4, the housing 10 is formed in a substantially rectangular tubular shape. The housing 10 is provided with a flange portion 11 that protrudes outwardly on the opposite side (front side) to the side (rear side) where it is assembled to the fuel filler port 3. An arm storage chamber 12 that protrudes outward is provided on the right side of the housing 10.

[0026] As shown in Fig. 4, a shaft hole 13 is provided on the front side of the underside of the arm accommodating chamber 12, penetrating in the vertical direction. A rotating shaft portion 51 of a shaft member 50, which will be described later, is inserted into the shaft hole 13. A peripheral portion 13a, which protrudes downward from the underside of the arm accommodating chamber 12, is provided on the lower edge of the shaft hole 13. A housing side holding portion 14, which holds one end 60a of a biasing member 60, which will be described later, is provided near the peripheral portion 13a. In addition, a sliding contact portion 15, with which an extension piece 56 of the shaft member 50, which will be described later, comes into sliding contact, is provided on the rear side of the underside of the arm accommodating chamber 12.

[0027] The sliding contact portion 15 has an inclined surface 15a formed in an inclined manner on the closed position side in the rotation direction of the lid 20, where the midpoint of sliding contact with a protruding end surface 57a of the shaft member 50 described later is located closer to the extending piece 56 (lower) in the vertical direction than the sliding contact start position. The sliding contact portion 15 also has a horizontal surface 15b, which is a plane perpendicular to the vertical direction, on the open position side in the rotation direction. The inclined surface 15a and the horizontal surface 15b are formed integrally.

[0028] A wall portion 16 is provided downward at the end of the horizontal surface 15b on the open position side in the rotation direction. A rib 17 is provided at the lower end of the wall portion 16 and extends approximately parallel to the horizontal surface 15b in the up-down direction.

[0029] A fitting hole 19 penetrating in the front-rear direction is provided on the left side of the housing 10. A fitting protrusion 32 of the lid 20, which will be described later, is inserted and fitted into the fitting hole 19. This keeps the lid 20 closed.

[0030] Next, the lid 20 will be described. The lid 20 is rotatably supported by an axis member 50, and configured to be displaceable between a closed state (see FIG. 2(a)) and a closed state (see FIG. 2(b)). As shown in FIG. 3, the lid 20 is configured to have a support body 20A and a lid body 20B. The support body 20A is configured integrally with a main body portion 21 and an arm portion 22. The main body portion 21 is formed in a substantially plate-like shape, and the lid body 20B is attached to the front side of the main body portion 21. The arm portion 22 is integrally connected to the right side of the main body portion 21, and is formed in a substantially U-shape when viewed in the vertical direction, curved so as to be convex toward the rear.

[0031] The support body 20A is assembled to the housing 10 by inserting the arm portion 22 from the front side of the housing 10 and accommodating it in the arm accommodating chamber 12, and the tip portion 23 of the arm portion 22 accommodated in the arm accommodating chamber 12 is rotatably supported by a rotating shaft portion 51 of a shaft member 50 described later. This allows the lid 20 to be opened and closed relative to the opening in which the flange portion 11 of the housing 10 is provided. Note that the tip portion 23 of the arm portion 22 is provided with an engaged projection 24 to engage with an engaging projection 55 of the shaft member 50 described later (see also FIG. 5(a)).

[0032] 3 and 5, a peripheral wall portion 25 that protrudes forward is provided on the periphery of the main body portion 21. A flat plate portion 26 is provided in the central portion of the main body portion 21, and a label (not shown) indicating, for example, the type of fuel to be filled through the filler opening 3 can be affixed to the rear surface of the flat plate portion 26.

[0033] As shown in Fig. 5, a pair of reinforcing ribs 27, 28 are provided on the front side of the main body 21. The reinforcing ribs 27, 28 are formed along the left-right direction. Specifically, the reinforcing rib 27 is formed on the upper part of the flat plate portion 26, and the reinforcing rib 28 is formed on the lower part of the flat plate portion 26. The upper surfaces of the reinforcing ribs 27, 28 are inclined surfaces with the free ends facing downward. The strength of the lid 20 is increased by providing the reinforcing ribs 27, 28 on the main body portion 21.

[0034] Each of the reinforcing ribs 27 and 28 has three L-shaped locking claws 29 on the opposing sides. That is, the locking claws 29 are formed on the lower surface of the reinforcing rib 27 and the upper surface of the reinforcing rib 28, and are arranged at intervals in the left-right direction.

[0035] A locking claw 30 is formed on the lower surface of the reinforcing rib 27 and the upper surface of the reinforcing rib 28. The locking claw 30 is formed at a position of the locking claw 29 that is the farthest (leftmost) from the arm portion 22 among the locking claws 29.

[0036] An engagement recess 31 is provided on the right side of the peripheral wall 25 of the main body 21. An engagement protrusion 46 of the lid 20B, which will be described later, is engaged with the engagement recess 31.

[0037] A fitting protrusion 32 that protrudes rearward is provided on the rear surface of the main body 21 in correspondence with the fitting hole 19 of the housing 10. The lid 20 is maintained in a closed state by inserting and fitting the fitting protrusion 32 into the fitting hole 19.

[0038] The lid body 20B is formed to have an outer shape larger than that of the main body 21 of the support 20A and is formed to have a curved shape such that the flat plate is gently convex toward the front, and is attached to the main body 21. As a result, the lid body 20B is attached to the main body 21 with the entire peripheral edge portion protruding from the outer periphery of the main body 21.

[0039] On the rear surface of the lid 20B, which is the mounting surface to the main body 21, two locking portions 41, 42 are provided at a distance in the up-down direction so as to correspond to the reinforcing ribs 27, 28 of the main body 21. The locking portions 41, 42 are formed along the left-right direction. Each of the locking portions 41, 42 has three L-shaped locking claws 43 protruding in opposite directions and one locking portion 44. The locking claws 43 are formed at a distance in the left-right direction. The locking portion 44 is formed with a locking claw 45, which is disposed near one of the locking claws 43 on the left side of the lid 20B. Furthermore, an engagement protrusion 46 extending in the left-right direction is formed on the right side of the rear surface of the lid 20B.

[0040] Here, when attaching the lid body 20B to the support body 20A, first, the lid body 20B is placed against the body part 21 of the support body 20A in a state where it is shifted to the left, and the rear surface of the lid body 20B is abutted against the peripheral edge of the peripheral wall part 25 of the body part 21. In this state, the locking claw 45 of the lid body 20B is located near the locking claw 30 of the body part 21, the engaging claw 43 of the lid body 20B is located near the engaging claw 29 of the body part 21, and the engaging protrusion 46 of the lid body 20B is engaged with the engaging recess 31 of the body part 21.

[0041] Thereafter, the lid body 20B is slid to the right relative to the main body 21. At this time, the engagement protrusion 46 of the lid body 20B engages with the engagement recess 31 of the main body 21, so that the lid body 20B is guided and smoothly slid relative to the main body 21. When the lid body 20B is slid to the right relative to the main body 21, the locking claw 45 of the lid body 20B is engaged with the locking claw 30 of the main body 21, and the locking claw 43 of the lid body 20B is engaged with the locking claw 29 of the main body 21. This completes the attachment of the lid body 20B to the support body 20A (specifically, the main body 21).

[0042] Next, the shaft member 50 will be described. The shaft member 50 is journalled to the housing 10 and rotatably supports the lid 20. As shown in Fig. 7, the shaft member 50 integrally includes a generally pin-shaped pivot shaft portion 51 extending in the vertical direction, a mounted portion 52 formed in a generally cylindrical shape with a larger diameter than the pivot shaft portion 51 and on which the biasing member 60 is mounted, and a generally semi-cylindrical peripheral wall portion 54 covering half of the outer periphery of the mounted portion 52 so as to define a space 53 between the mounted portion 52 and the pivot shaft portion 51.

[0043] The pivot shaft portion 51 is inserted into the shaft hole 13 of the housing 10 to rotatably support the lid 20. The pivot shaft portion 51 is provided with a locking projection 55 that is locked to the locked projection 24 of the lid 20. The locking projection 55 is locked to the locked projection 24 of the lid 20, so that the shaft member 50 supports the lid 20 and is prevented from falling off the lid 20.

[0044] The peripheral wall 54 is integrally provided with a cantilever-shaped extension piece 56 extending to the right side, and configured to be elastically deformable in the axial direction, which is a direction intersecting the extension direction (left-right direction in this example), that is, in the up-down direction in this example. The extension piece 56 is elastically deformed in the up-down direction (particularly downward in this example) by sliding contact with the sliding contact portion 15, as described later. A protruding portion 57 is provided at the extending end (right end in this example) of the extension piece 56, which protrudes toward the sliding contact portion 15 side (upper side) in the up-down direction. The protruding portion 57 has a protruding end surface 57a (upper surface) that serves as a sliding contact surface with the sliding contact portion 15 of the housing 10. The protruding end surface 57a is formed in an inclined shape corresponding to the inclined surface 15a so as to be in surface contact with the inclined surface 15a of the sliding contact portion 15.

[0045] The peripheral wall 54 is provided with a reinforcing portion 58 formed in a substantially U-shape, both ends of which are connected to the peripheral wall 54. When the lid 20 is in an open state, the reinforcing portion 58 is engaged with or interfered with by the rib 17 of the housing 10 when the elastic force of the extension piece 56 acts on the shaft member 50 in the axial direction toward the side where the shaft member 50 falls off the housing 10 (the lower side in this example). That is, the reinforcing portion 58, together with the rib 17 of the housing 10, prevents the shaft member 50 from falling off the housing 10. The lower surface of the reinforcing portion 58 is provided with a shaft member side holding portion 59 that holds the other end 60b of the biasing member 60 described later. The strength of the shaft member side holding portion 59 is increased by the reinforcing portion 58.

[0046] Next, the biasing member 60 will be described. As shown in Fig. 8, the biasing member 60 is a so-called torsion spring, with one end 60a held by the housing side holding portion 14 of the housing 10 and the other end 60b held by the shaft member side holding portion 59 of the shaft member 50. As a result, the lid device 1 is configured to be rotated in the fully open direction by the biasing force of the biasing member 60 when the lock is released.

[0047] The above has described the housing 10, the lid 20, the shaft member 50, and the biasing member 60 that constitute the lid device 1. Below, a description will be given of the operation of the extension piece 56 when the lid 20 is displaced from the closed position to the open position.

[0048] In the lid device 1, when the lock between the housing 10 and the lid 20 is released, the lid 20 is rotated toward the open position by the biasing force of the biasing member 60. At this time, in accordance with the rotation of the rotation shaft portion 51, the extension piece 56 also rotates in the same manner.

[0049] During the rotational process, the protruding end surface 57a of the protruding portion 57 of the extension piece 56 comes into contact with the inclined surface 15a of the sliding contact portion 15 of the housing 10, and the protruding end surface 57a starts to slide against the inclined surface 15a. Then, as the rotation of the lid 20 progresses, the extension piece 56 slides up the inclined surface 15a while elastically deforming. As a result, as the lid 20 approaches the open position, the friction generated between the extension piece 56 and the inclined surface 15a gradually increases, and the opening speed of the lid 20 is gradually attenuated. After that, when the lid 20 reaches the vicinity of the open position, the protruding end surface 57a climbs up the inclined surface 15a, and when the lid 20 reaches the open position, the protruding end surface 57a is disposed on the horizontal surface 15b. The above describes the operation of the extension piece 56 when the lid 20 is displaced from the closed position to the open position.

[0050] As described above, according to this embodiment, when the lid 20 is displaced from the closed position to the open position, the extension piece 56 provided on the shaft member 50 comes into sliding contact with the sliding contact portion 15 provided on the housing 10. That is, when the lid 20 is opened, the extension piece 56 comes into sliding contact with the sliding contact portion 15, which generates friction between the extension piece 56 and the sliding contact portion 15, thereby making it possible to suppress the momentum with which the lid 20 opens. In this manner, the lid device 1 according to this embodiment can suppress the force with which the lid 20 opens with a simple structure.

[0051] Furthermore, according to this embodiment, the inclined surface 15a of the sliding contact portion 15 is formed in an inclined shape such that the midpoint of sliding contact with the extension piece 56 is located closer to the extension piece 56 side (lower side) in the vertical direction than the sliding contact start position, and the extension piece 56 is provided in a cantilever shape. As a result, from the sliding contact start stage of the extension piece 56 to the sliding contact midpoint of the extension piece 56 on the inclined surface 15a, the extension piece 56 slides up the inclined surface 15a while elastically deforming, so that the friction generated between the extension piece 56 and the inclined surface 15a gradually increases as the lid 20 approaches the open position. That is, the momentum when the lid 20 opens can be gradually reduced while suppressing the load on the lid device 1 when the lid is opened. Also, by changing the inclination angle of the inclined surface 15a, the magnitude of the friction generated between the extension piece 56 and the inclined surface 15a changes, so that the momentum when the lid 20 opens can be adjusted.

[0052] Furthermore, according to this embodiment, the extending end of the extending piece 56 is provided with a protruding portion 57 whose protruding end surface 57a is in sliding contact with the sliding contact portion 15. Thus, by changing the area of ​​the protruding end surface 57a, the magnitude of friction generated between the protruding end surface 57a and the sliding contact portion 15 changes, so that the momentum with which the lid 20 opens can be adjusted.

[0053] Furthermore, according to this embodiment, the protruding end face 57a is formed in an inclined manner so as to be in face-to-face contact with the inclined surface 15a, so that the protruding end face 57a and the inclined surface 15a are more closely engaged when they slide in contact with each other, thereby more appropriately suppressing the momentum when the lid 20 is opened.

[0054] The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, etc. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited.
