Detailed Description

Hereinafter, an embodiment of the present invention will be described with reference to the drawings as appropriate. The same components are denoted by the same reference numerals, and redundant description thereof is omitted. When directions are described, they are basically described based on front and back, left and right, or up and down as viewed from the driver unless otherwise specified. The "vehicle width direction" is synonymous with the "left-right direction".

Fig. 1 shows a push-up device 1 according to an embodiment of the present invention.

A fuel filler of a vehicle is provided with a fuel lid which can be opened to the outside of the vehicle from a closed state covering the fuel filler. A push-up device 1 for pushing the back surface of the fuel lid to open the fuel lid is disposed on the back side of the fuel lid.

The push-up device 1 of the present embodiment includes: a box-shaped main body casing 2; a rod 3 provided to be able to advance and retreat with respect to the fuel cap; and a spring 4 (see fig. 4) as an urging mechanism for urging the lever 3 toward the fuel lid.

As shown in fig. 1, the push-up device 1 further includes: a locking member 5 which is engaged with the rod 3 to lock the rod 3 to move in and out; a rotating member 6 coupled to the lock member 5 and configured to rotate to release the engagement between the lever 3 and the lock member 5; an operation lever 7 coupled to the rotating member 6 to rotate the rotating member 6; and a guide portion 8 provided in the main body casing 2 and contacting the operation lever 7 to regulate the operation direction of the operation lever 7.

The main body case 2 is a hollow square box-shaped resin case, and accommodates a rod 3, a spring 4, a lock member 5, a motor 9 that linearly moves the lock member 5 by rotation, and the like in an internal space. Further, a lower attachment piece 2b is integrally projected from the main body case 2. The main body case 2 is attached to the vehicle body by the lower attachment piece 2b, and is thereby disposed at a position where the lever 3 can be pressed against the back surface of the fuel lid.

As shown in fig. 4, the rod 3 is formed in a substantially cylindrical shape, and has a tip end portion 3a protruding from a rod hole 2a formed in the main body casing 2; an intermediate portion 3c which can be housed so as to advance and retreat mainly in the main body case 2; and a rear end portion 3b urged by a spring 4.

The distal end portion 3a is inserted into the rod hole 2a of the main body case 2, and a distal end surface abutting on the back surface side of the fuel lid is provided to protrude outside the rod hole 2 a.

Further, a rubber seal ring 13 and a cover member 14 are provided between the distal end portion 3a and the peripheral edge portion of the rod hole 2 a. The seal ring 13 is formed with a hole portion allowing the distal end portion 3a to move in the advancing/retreating direction, and is attached so as not to fall off through the cover member 14.

Further, a spring 4 is disposed between the rear end portion 3b and the inner side surface of the main body case 2. The spring 4 presses the rear end portion 3b of the lever 3 in the lever axis direction. Thereby, the distal end portion 3a is biased in a direction protruding outward from the rod hole 2 a.

Further, around the rear end portion 3b, a rod holding member 12 is fitted into a fitting groove annularly recessed in the outer peripheral surface. The rod holding member 12 moves in the advancing and retreating direction together with the rod 3. At this time, the rod holding member 12 slides in the main body case 2, and the rod 3 smoothly moves in the forward and backward direction.

The lever 3 of the present embodiment is provided so as to be able to advance and retreat between a retreat position (see the solid line position in fig. 4) retreating into the main body case 2 against the urging force of the spring 4 and a pressing position pressing the back surface of the cover by further protruding the distal end portion 3a from the lever hole 2 a.

Further, a lock member 5 is housed inside the main body case 2. The lock member 5 is formed in a substantially rectangular parallelepiped shape and is provided so as to be movable in a direction orthogonal to the axial direction of the rod 3. On the other hand, a locking groove 3d capable of engaging the lock member 5 is recessed in an outer peripheral surface of the intermediate portion 3c of the lever 3.

The locking member 5 has a convex locking protrusion 5a protruding from a portion facing the locking groove 3 d. The lock member 5 of the present embodiment is further provided with a contact piece 5 b. When the locking convex portion 5a is locked with the locking groove 3d, the contact piece 5b contacts with the outer side surface of the lever 3, and locking by the locking convex portion 5a is stabilized (see fig. 6).

As shown in fig. 4, planar-toothed rack teeth 5c are formed on one side surface of the lock member 5. The rack teeth 5c mesh with pinion teeth 9a attached to a rotating shaft of the motor 9.

A connector 11 for transmitting an electric signal from the outside of the main body casing 2 to the motor 9 is fixed to the rear side surface of the main body casing 2.

The motor 9 rotates the pinion teeth 9a attached to the rotating shaft in the normal direction or the reverse direction based on an electric signal transmitted through the connector 11. The rack teeth 5c linearly advance and retreat the lock member 5 in accordance with the normal rotation or reverse rotation of the rotary shaft.

The locking convex portion 5a is inserted into and extracted from the locking groove 3d by the forward and backward movement of the locking member 5.

The lock member 5 can fix the lever 3 at the retreat position against the urging force of the spring 4 in a state where the locking convex portion 5a is inserted into the locking concave groove 3d and locked. Therefore, the distal end portion 3a of the rod 3 does not move in the direction protruding from the rod hole 2 a.

When the locking member 5 is retracted and the locking protrusion 5a is drawn out from the locking groove 3d, the lever 3 is moved in a direction protruding from the lever hole 2a by the biasing force of the spring 4.

The front end portion 3a of the lever 3 can open the fuel lid by pressing the back surface side of the fuel lid toward the vehicle outside.

When the fuel lid is closed, the front end portion 3a of the lever 3 is pressed by the back surface side of the fuel lid. Thereby, the lever is returned to the retracted position that can be locked using the lock member 5. Then, the locking convex portion 5a is inserted into the locking concave groove 3d and locked so as not to return the lever 3.

The push-up device 1 of the present embodiment is provided with a manual operation lever 7 (see fig. 2) for manually opening the fuel lid when the lever 3 cannot be projected by the motor 9 when no power is supplied or the like.

In the manual operation, as indicated by an arrow a in fig. 5, the user manually performs an operation of pulling the operation lever 7, thereby protruding the lever 3 and opening the fuel lid.

That is, the side surface of the lock member 5 on which the rack teeth 5c are formed (see fig. 4) is provided with a cylindrical engaging projection 5d projecting from the side surface on the opposite side as shown in fig. 5.

A turning member 6 is provided on the side surface of the main body casing 2 on which the operation lever 7 is provided. The rotating member 6 is pivotally supported so as to be rotatable about a rotating shaft 6c perpendicular to the side surface. The rotating member 6 has a concave recess 6b formed in a part of the side surface.

Further, a stopper 15 is provided on the same side surface of the main body casing 2 as the rotating member 6. The stopper 15 is of a mountain shape in side view in which the inclined surface portions on both left and right sides are inclined, and the

inclined surface portions

15a and 15b are in contact with the vertical wall portions of the rotating member 6 located on both circumferential sides of the recess 6b (see fig. 6 and 7). Thereby, the stopper 15 can limit the rotatable angle of the turning member 6 to a fixed range.

Further, the turning member 6 is provided with an elastic restoring member 16, and the turning member 6 is urged in a return direction opposite to the direction in which the operation lever 7 is pulled and turned.

As shown in fig. 1, a guide portion 8 is provided on the side surface of the main body case 2 on which the operation lever 7 is provided. The guide portion 8 is substantially gate-shaped when viewed from the front, and has a pair of upper and

lower column portions

8a, 8b provided on the left and right, and a connecting beam portion 8c connecting upper end portions of the upper and

lower column portions

8a, 8 b.

An engagement projection 8d is formed on the inner surface of the lower column portion 8 b. The locking projection 8d abuts on one side surface of the operating lever 7 inserted into the guide portion 8. As shown in fig. 3, the locking projection 8d is in point contact with the side surface of the operating lever 7 in a small area.

Fig. 6 shows a state in which the operation lever 7 is not operated before being pulled. In this state, the one end surface of the recess 6b of the rotating member 6 is pressed against the one inclined surface of the mountain-shaped stopper 15 in the side view by the biasing force of the elastic restoring member 16, and the rotation is stopped.

In a state where the operation lever 7 is not operated, the locking protrusion 5a of the lock member 5 is inserted into the locking groove 3d, and is locked so that the lever 3 does not protrude in the fuel lid direction.

Further, as shown in fig. 7, when the operating lever 7 is pulled, the turning member 6 turns against the urging force of the elastic restoring member 16. In this state, the other end surface of the recess 6b of the rotating member 6 can rotate until it abuts against the other inclined surface of the mountain-shaped stopper 15 in side view.

The rotating member 6 of the present embodiment is integrally provided with an engaging rod 6a that engages with the engaging projection 5 d.

The engaging lever 6a rotates with the rotation of the rotating member 6 while engaging with the engaging projection 5 d. Thereby, the lock member 5 linearly moves in the advancing and retreating direction by the rotation of the rotary member 6, and is inserted into and withdrawn from the locking groove 3 d.

When the locking protrusion 5a is drawn out from the locking groove 3d, the lever 3 is moved in a direction protruding from the lever hole 2a by the biasing force of the spring 4. Thus, the front end portion 3a of the lever 3 can press the back surface side of the fuel lid to open the fuel lid.

A fork 17 for engaging the operating lever 7 is integrally formed on the rotary member 6.

The center axis 17a of the fork 17 is set at a predetermined interval in the radial direction from the rotation axis 6 c. Therefore, the linear pulling force of the operating lever 7 engaging with the fork 17 becomes a force in the rotational direction that rotates the rotating member 6 about the rotating shaft 6c as the rotation center.

The center axis 17a of the fork 17 is formed perpendicular to the side surface of the main body housing 2 on which the operating lever 7 is provided. Thus, the rotation shaft 6c of the rotation member 6 and the center axis 17a of the fork 17 are provided so as to be perpendicular to the side surface of the main body housing 2 and parallel to the axial direction.

As shown in fig. 2, the operation lever 7 of the present embodiment includes: an engagement opening 7a engaged with the fork 17 of the rotating member 6; a wide shank portion 7 b; a fragile portion 7 c; and a ring-shaped operation ring portion 7d for an operator to hook a finger or the like.

The weak portion 7c is formed in a thin band shape having a width smaller in a direction orthogonal to the longitudinal direction than the stem portion 7b, which is the other portion. The weak portion 7c of the present embodiment is set so that the cross-sectional area in the direction perpendicular to the longitudinal direction is smaller than that of the stem portion 7 b.

The operating lever 7 is formed in a tapered shape in which the dimension in the thickness direction is substantially the same and the vicinity of the center of the wide shank portion 7b is made thin.

The weak portion 7c of the present embodiment has a sufficiently strong strength against a pulling force required to draw out the locking convex portion 5a from the locking concave groove 3d in order to rotate the rotating member 6.

The fragile portion 7c is configured to be broken by a force smaller than a force that breaks a device that presses the pop-up device 1, and the device includes an engagement mouth portion 7a that engages the fork portion 17, a pivot shaft 6c that pivotally supports the pivot member 6, and the like.

That is, when the operating ring portion 7d is pulled by an excessive force and a tensile force is applied in the longitudinal direction, the fragile portion 7c of the operating lever 7 is broken before the fork portion 17, the engagement opening portion 7a engaged with the fork portion 17, or the rotating shaft 6c of the shaft support rotating member 6 is broken. Therefore, the fork 17, the engagement opening 7a, and the rotating member 6 are less likely to be damaged.

In this way, when an excessive force is applied by an operation from the vehicle interior, the operation lever 7 is pulled off, and the mechanism of the push-up device 1 is protected. Therefore, the emergency release function can be easily restored by merely replacing the broken operation lever 7.

As shown in fig. 2, in the operating lever 7 of the present embodiment, a stepped portion 7e is formed in a part of the stem portion 7b (see fig. 3). In the present embodiment, when the operation lever 7 is pulled, the operation for pulling is performed so as to avoid the step portion 7e from coming into contact with the lower column portion 8b of the guide portion 8, and the direction of the operation lever 7 becomes almost horizontal as shown by an arrow a in fig. 5.

The stepped portion 7e of the operating lever 7 of the present embodiment is provided with a tapered surface 7 f. The tapered surface 7f includes an inclined surface that gradually changes in width dimension orthogonal to the longitudinal direction from the fragile portion 7c toward the shank portion 7 b. The stepped portion 7e of the present embodiment has a pair of tapered surfaces 7f inclined so as to be substantially symmetrical with respect to the central axis on both sides in the width direction of the operating lever 7.

For example, as shown in fig. 1, in the retracted state (see fig. 6) in which the lever 3 is locked by the lock member 5, the operation ring portion 7d of the operation lever 7 is located downward so as to avoid the connector 11.

On the other hand, the fork 17 for locking the engagement mouth portion 7a on the opposite side of the operation lever 7 is located at a high position. However, as shown in fig. 3, the locking projection 8d on the side of the operation ring portion 7d locks the stepped portion 7e at a connection portion with the narrow band-shaped weak portion 7c at the near side.

The arrangement position of the lower column portion 8b can reduce the arrangement of the operation ring portion 7d in the retracted state as shown by a virtual line in fig. 5. In this embodiment, the fragile portion 7c has a thin belt shape. Therefore, the arrangement of the operation ring portion 7d can be further reduced.

Therefore, the operation ring portion 7d is disposed away from the connector 11 downward. This allows the operator to easily pinch the operation ring portion 7d and pull it out with the finger hook.

When the operation ring portion 7d is pulled in the direction of arrow b in fig. 3, the step portion 7e rises along the inner surface of the lower column portion 8b, and the operation ring portion 7d is lifted. Thus, when the operating lever 7 is substantially horizontal, the operating ring portion 7d is pulled substantially horizontally toward the vehicle interior side.

The tapered surface 7f of the present embodiment includes an inclined surface that gradually increases in width dimension orthogonal to the longitudinal direction from the fragile portion 7c toward the shank portion 7 b. Therefore, the stepped portion 7e can release the locking while smoothly sliding in contact with the locking projection 8 d.

As shown by a solid line in fig. 5, the rotation member 6 starts rotating in accordance with an operation of the step portion 7e passing over the locking protrusion 8d and pulling the operation lever 7 in a substantially horizontal direction.

At this time, the inner surface of the guide portion 8, particularly the lower column portion 8b, smoothly guides the side surface of the stem portion 7b of the operating rod 7 inserted inside.

Therefore, even if the vertical position of the fork 17 of the turning member 6 is moved by the rotation, the operation lever 7 can be linearly pulled in a substantially horizontal direction. Therefore, when the operation opening portion is formed in the garnish on the indoor side, it is not necessary to enlarge the opening area of the operation opening portion necessary for the operation.

Further, the force of the operating lever 7 can be efficiently transmitted from the turning member 6 to the lock member 5.

The turning member 6 rotates about the turning shaft 6c in accordance with the movement of the operating lever 7. The lock member 5 is pushed up by an engagement rod 6a that rotates together with the pivot member 6 (see fig. 5).

The lever 3 is inserted from the locking state (see fig. 6) in which the locking convex portion 5a of the locking groove 3d is locked, and the locking is released by withdrawing the locking convex portion 5a (see fig. 7).

As shown in fig. 4, the lever 3 is urged in a direction protruding from the lever hole 2a by the urging force of the spring 4.

Therefore, the lever 3 is moved in a direction protruding from the lever hole 2a by releasing the lock, and the distal end surface of the distal end portion 3a is pressed against the back surface side of the fuel lid.

Next, the operation and effects of the push-up device of the present embodiment will be described.

As shown in fig. 4, the push-up device 1 of the present embodiment includes a lever 3 provided to be able to advance and retreat with respect to the fuel lid, and a spring 4 serving as a biasing mechanism for biasing the lever 3 toward the fuel lid.

The operation lever 7 has a stepped portion 7e on the side surface on the guide portion 8 side.

According to the above configuration, the push-up device 1 can be provided, which can improve the degree of freedom of layout setting of the previous position and restrict the operation direction.

That is, the previous position of the operation lever 7 can be set to a desired position as a part of the side surface of the operation lever 7 on the side of the guide portion 8 is locked by the guide portion 8.

Further, by performing an operation of pulling away the stepped portion 7e so as not to abut on it or by causing the stepped portion 7e to pass over the guide portion 8 during the operation, the operation direction of the operation lever 7 can be restricted to be substantially horizontal to the vehicle interior direction. For example, when the operator pulls the operation lever 7 downward as indicated by an arrow b in fig. 3, the guide portion 8 guides the operation lever 7, and the operator is urged to pull the operation lever 7 in a substantially horizontal direction as indicated by an arrow a in fig. 5.

Further, the opening area of the opening portion on the indoor side for lever operation can be set small.

For example, when a lever for rotating the rotating member 6 is directly attached, the lever draws an arc and requires a large opening on the indoor side. In comparison with this case, the push-up device of the present embodiment can set the opening area to be small.

The guide portion 8 allows the operation lever 7 to be oriented in a desired direction and the operation direction to be changed.

Therefore, the push-up device 1 according to the present embodiment can easily open the fuel lid by simply pulling the operation lever 7 even in a non-energized state where the motor 9 does not normally function, and the like, and is a device having excellent usability.

As shown in fig. 1, the operating lever 7 is rotatably coupled to the rotating member 6, and the rotating shaft 6c of the rotating member 6 and the central axis 17a of the operating lever 7 are arranged in parallel.

According to the above configuration, the center axis 17a of the fork 17 that engages the operating lever 7 provided on the rotating member 6 is moved by rotating around the rotating shaft 6c of the rotating member 6. The linear pulling force of the operating lever 7 engaged with the fork 17 becomes a force in the rotational direction that rotates the rotating member 6 around the rotating shaft 6c as the rotation center. Therefore, the operation based on the operation lever 7 is smoothly transmitted until the lock release. Therefore, the device can be further used with good convenience.

As shown in fig. 1, the locking projection 8d provided on the guide portion 8 contacts the operating lever 7 to regulate the operating direction of the operating lever 7. According to the above configuration, for example, the operation ring portion 7d of the operation lever 7 can be held substantially horizontally by a finger from a lower position avoiding the connector 11. Therefore, the device can be further used with good convenience.

The stepped portion 7e has a tapered surface 7 f.

According to the above configuration, the locking protrusion 8d can smoothly go over the stepped portion along the shape of the tapered surface 7 f. Therefore, the device can be further used with good convenience.

Further, a fragile portion 7c is provided at least in a part of the operation lever 7.

According to the above configuration, the fragile portion 7c is broken before the device is broken. Therefore, important parts of the mechanism constituting the push-up device 1 are protected.

The fragile portion 7c is a thin band having a narrow width in a direction orthogonal to the longitudinal direction.

According to the above configuration, even if the weak portion 7c is broken from the thin band-shaped portion, the emergency release function of the push-up device 1 can be easily restored by merely replacing the broken operating lever 7.

The present invention is not limited to the above embodiments, and various modifications can be made. The above-described embodiments are examples for explaining the present invention to facilitate understanding, and are not limited to having all the configurations described. Further, a part of the configuration of one embodiment may be replaced with the configuration of another embodiment, and the configuration of another embodiment may be added to the configuration of one embodiment. Further, a part of the configuration of each embodiment can be deleted, or other configurations can be added or replaced. Possible modifications to the above-described embodiment are described below, for example.

In the present embodiment, the description has been given using the push-up device 1 for a fuel cap provided at a fuel filler of a vehicle, but the present invention is not particularly limited thereto. For example, a cover for a charging opening of an electric vehicle may be applied to various covers as long as the cover can be opened by being pressed from the back side of the cover.

In the present embodiment, the pair of tapered

surfaces

7f, 7f are formed obliquely on both sides so as to be substantially symmetrical on both sides in the width direction of the operation lever 7 with the center axis therebetween. However, the present invention is not particularly limited to this, and the tapered surface 7f may be provided on the side closer to the locking protrusion 8d, and the shape, number, and material of the tapered surface 7f and the fragile portion 7c are not particularly limited.

In the present embodiment, a description is given of a device in which the tapered surface 7f is provided in the stepped portion 7e, but the present invention is not particularly limited thereto. For example, the tapered surface 7f may be omitted, and a slope, a stepped slope, or the like may be provided, and the shape of the stepped portion 7e is not particularly limited, and may be configured in various ways as long as it is formed on the side surface of the operation lever 7 on the side of the guide portion 8.

In the present embodiment, the locking projection 8d is formed on the guide portion 8 to reduce friction by making point contact with the side surface of the operating lever 7, but the present invention is not particularly limited thereto. For example, the guide portion 8 may be formed in a tapered shape, and the shape of the guide portion 8 may be various shapes as long as the guide portion is configured to contact the operation lever 7 to regulate the operation direction of the operation lever 7.

The tapered surface may be formed on at least one of the side surfaces on the side of the stepped portion 7e and the guide portion 8. The stepped portion 7e allows setting of the previous arrangement of the operating lever 7, and as shown by an arrow a in fig. 5, the tapered surface need not be particularly provided as long as the direction in which the operating lever 7 is pulled is substantially horizontal.
