Description

[Technical Field]

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

[0002] The lid opening and closing device disclosed in Patent Document 1 includes a lid that opens and closes the opening of an energy receiving port provided in a vehicle, and an opening and closing device that opens and closes the lid. This opening and closing device includes a link mechanism that connects the lid to the vehicle body, and an electric motor that drives the link mechanism. The link mechanism is actuated by the driving force of the electric motor, causing the lid to move between a fully closed position where the opening is closed and a fully open position where the opening is open. In other words, the lid opens and closes automatically. [Prior art documents] [Patent documents]

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

[0004] The lid opening and closing device of Patent Document 1 does not have a locking mechanism that prevents the lid from operating in the fully closed position. Adding a locking mechanism can improve the safety of the lid opening and closing device. For example, by providing a locking member for locking the lid in the fully closed position and a drive mechanism for driving the locking member, the lid can be prevented from operating in the closed position. However, in this case, a drive mechanism for the locking member must be provided separately from the motor for opening and closing the lid, which increases the number of parts in the lid opening and closing device and makes it more complicated.

[0005] An object of the present invention is to provide a lid opening and closing device that can lock a lid while suppressing an increase in the number of parts and complexity. [Means for solving the problem]

[0006] One aspect of the present invention is a vehicle door lock system including an electric motor, a drive lever that rotates about a drive shaft by the driving force of the electric motor and has an operation unit, a lid that is configured to be movable between a fully closed position that closes an opening in a vehicle body and a fully open position that opens the opening, and a spindle lever that is rotatable about a spindle shaft and has an operation receiving unit that abuts against the operation unit, and that rotates about the spindle shaft by operation force from the operation unit received by the operation receiving unit so that the lid moves in conjunction with the fully closed position and the fully open position, wherein the axis of the drive shaft and the axis of the spindle shaft extend in the same direction, and the drive shaft and the spindle shaft are disposed at positions eccentric to each other when viewed in the direction of extension of the axis, and the operation receiving unit is configured to be rotatable about the spindle shaft by the driving force of the electric motor. Therefore, a lid opening and closing device is provided, which has an opening operation portion that contacts the operating portion when the drive lever rotates in the opening drive direction, thereby rotating the spindle lever in the opening operation direction in which the lid moves in conjunction with the opening operation portion, a closing operation portion that contacts the operating portion when the drive lever rotates in the closing drive direction opposite to the opening drive direction by the driving force of the electric motor, thereby rotating the spindle lever in the closing operation direction in which the lid moves in conjunction with the opening operation portion, and a lock operation portion that contacts the operating portion when the spindle lever is urged in the opening operation direction by an external force that acts on the lid in the fully closed position and attempts to move it to the fully open position.

[0007] The lid is moved between the fully open and fully closed positions by the driving force of the electric motor when the operating portion of the drive lever abuts against the opening and closing portions of the operation receiving portion of the spindle lever. When an external force acts on the lid in the fully closed position to move it to the open position, the spindle lever is biased in the opening direction, but the drive lever, whose operating portion abuts against the locking portion of the operation receiving portion on the spindle lever, is prevented from rotating in the opening direction. As a result, the spindle lever does not rotate in the opening direction, and the lid remains in the fully closed position, i.e., locked. Thus, locking the lid in the fully closed position is achieved using two components, the drive lever and the spindle lever, eliminating the need for a lock lever or a drive unit for operating the lock lever. Therefore, the lid opening / closing device of the present invention can lock the lid without increasing the number of parts or complexity, thereby reducing the manufacturing costs of the lid opening / closing device. [Effects of the Invention]

[0008] According to the lid opening and closing device of the present invention, it is possible to lock the lid while suppressing an increase in the number of parts, complexity, and resulting cost increase. [Brief explanation of the drawings]

[0010] 1 and 2, a lid opening and closing device 1 according to an embodiment of the present invention is attached to a through-hole 2a (opening) in a side panel 2 that constitutes the body of an automobile, which is an example of a vehicle. A power supply connector 3, which is an example of a power receiving portion, is provided on the interior side of the side panel 2 so as to face the through-hole 2a. The power receiving portion may be a supply port for liquid fuel such as gasoline or diesel, or liquid fuel such as liquefied hydrogen or LP gas, or other gaseous or solid fuels.

[0011] In the figure, the X direction, Y direction, and Z direction are the vehicle length direction, vehicle width direction, and vehicle height direction of the automobile, respectively.

[0012] The lid opening and closing device 1 includes a frame 5, a lid 6, a link mechanism 7, a drive mechanism 8, and an emergency mechanism 9.

[0013] The frame 5 is shaped like a shallow container with an opening on the outside of the vehicle, and is attached to the side panel 2 from the inside of the vehicle so as to cover the through-hole 2a. A window hole 5a is provided in the center of the frame 5 so as to face the power supply connector 3 in the vehicle width direction.

[0014] The lid 6 is configured to be movable up and down when viewed from the vehicle width direction between a position where it completely blocks the opening of the frame 5 shown in Figure 3, i.e., a fully closed position where it blocks the through hole 2a, and a position where it completely opens the opening of the frame 5 shown in Figures 1 and 2, i.e., a fully open position where it completely opens the through hole 2a and allows access to the power supply connector 3.

[0015] The link mechanism 7 connects the lid 6 to the frame 5 so that the lid 6 can move between a fully closed position and a fully open position. As will be described later, the link mechanism 7 is actuated by a rotational driving force transmitted from a driving mechanism 8, thereby moving the lid 6 between the fully closed position and the fully open position.

[0016] 4 and 5, the link mechanism 7 includes a first link member 11 and a second link member 12. As shown in FIG.

[0017] The first link member 11 includes a connecting portion 11a extending in the vehicle length direction, a first arm portion 11b extending from one end of the connecting portion 11a, and a second arm portion 11c extending from the other end of the connecting portion 11a.

[0018] Both ends of the connecting portion 11a are connected to the lid 6 so as to be rotatable about a horizontal axis AX1 extending in the vehicle length direction. Specifically, pins 11d protruding from both ends of the connecting portion 11a are inserted into bearing holes 6a (shown only in FIG. 5) provided in the lid 6. The tip of the first arm portion 11b is connected to the frame 5 so as to be rotatable about a horizontal axis AX2 extending in the vehicle length direction at a position spaced downward from the axis AX1. Specifically, pin 11e protruding from the tip of the first arm portion 11b is inserted into a bearing hole 5b (shown only in FIG. 4) provided in the frame 5. As will be described later, the tip of the second arm portion 11c is rotatable about the axis AX2, centered on the spindle shaft 26b, together with the spindle lever 26 of the link mechanism 7, relative to the frame 5.

[0019] The second link member 12 is disposed adjacent to the second arm portion 11c of the first link member 11. One end (the upper end in FIGS. 4 and 5) of the second link member 12 is rotatably connected to the lid 6 about a horizontal axis AX3 extending in the vehicle length direction at a position spaced above the axis AX1. Specifically, a pin 12a protruding from one end of the second link member 12 is inserted into a bearing hole 6b (shown only in FIG. 5) provided in the lid 6. The other end (the lower end in FIGS. 4 and 5) of the second link member 12 is rotatably connected to the frame 5 about a horizontal axis AX4 extending in the vehicle length direction at a position spaced above the axis A2. Specifically, a pin 12b protruding from the other end of the second link member 12 is inserted into a bearing hole 5c provided in the frame 5.

[0020] As described above, the lid 6 is connected to the frame 5 via the link mechanism 7 so as to have four rotation axes AX1 to AX4. The frame 5, the first link member 11, the second link member 12, and the lid 6 form a kind of four-link rotation chain.

[0021] 4 and 5, the drive mechanism 8 includes an actuator 22 that includes the electric motor 21 and outputs the rotational drive force of the electric motor 21 from an output portion 22a. The rotational drive force output from the output portion 22a of the actuator 22 rotates forward and backward around a horizontal axis AX5 that extends in the vehicle length direction at a position spaced upward from the axis AX2. The drive mechanism 8 also includes a transmission mechanism 23 that is interposed between the actuator 22 and the link mechanism 7 and operates the link mechanism 7 in response to the rotational drive force of the electric motor 21 to move the lid 6 between the fully closed position and the fully open position.

[0022] As shown most clearly in Figure 5, the transmission mechanism 23 includes a casing 24 fixed to the vehicle interior side of the frame 5. The casing 24 includes a shallow, container-shaped main body 24a with an open side, and a cover 24b that closes the opening of the main body 24a. The main body 24a is provided with a stopper 24c (shown only in Figure 10).

[0023] The transmission mechanism 23 will be outlined with reference to FIGS.

[0024] The transmission mechanism 23 includes a drive lever 25 and a spindle lever 26. The drive lever 25 is connected to the actuator 22 so as to transmit a rotational driving force. The spindle lever 26 is connected to the tip of the second arm portion 11c of the first link member 11 constituting the link mechanism 7 so as not to rotate relative to the first link member 11. The spindle lever 26 and the first link member 11 may be a single member. When the drive lever 25 is rotated by the rotational driving force of the electric motor 21 output from the output portion 22a of the actuator 22, this rotation is transmitted to the spindle lever 26 by the engagement of an operating portion 25c (described later) with a groove 31, and the spindle lever 26 rotates. As a result, the first link member 11 rotates together with the spindle lever 26, thereby operating the link mechanism 7. The transmission mechanism 23 constitutes a kind of counter cam or reverse cam, in which the drive lever 25 is a driving lever and the spindle lever 26 is a driven lever.

[0025] The transmission mechanism 23 will be described in more detail below.

[0026] 4 to 6, the drive lever 25 includes an arm 25a housed inside the casing 24 (a closed space defined by the main body 24a and the cover 24b) and a drive shaft 25b protruding in the vehicle length direction from one end of the arm 25a. The drive shaft 25b passes through the cover 24b of the casing 24 and is fitted to the output portion 22a of the actuator 22. Therefore, the drive lever 25 rotates around the axis AX5, centered on the drive shaft 25b, by the driving force of the electric motor 21 included in the actuator 22. Also referring to FIG. 9, a short cylindrical or pin-shaped operating portion 25c is provided at the other end of the arm 25a so as to protrude in the vehicle length direction.

[0027] Continuing to refer to FIGS. 4 to 6, the spindle lever 26 includes an arm 26a housed inside the casing 24 and a spindle shaft 26b protruding in the vehicle length direction from one end of the arm 26a. The arm 26a is disposed at the bottom of the main body 24a of the casing 24, and the arm 25a of the drive lever 25 is disposed so as to overlap with the arm 26a. The spindle shaft 26b is inserted into a through-hole 24d provided in the bottom wall of the main body 24a and protrudes outside the casing 24. Referring also to FIGS. 7 to 9, the portion of the spindle shaft 26b protruding from the casing 24 is provided with an insertion portion 26c having a non-circular cross section. Meanwhile, the second arm portion 11c of the first link member 11 is provided with a non-circular connecting hole 11f at the end opposite the connecting portion 11a. By inserting the insertion portion 26c into the connecting hole 11f, the spindle lever 26 and the first link member 11 are connected so that they cannot rotate relative to each other, and when the spindle lever 26 rotates around the axis AX2, the first link member 11 also rotates around the axis AX2.

[0028] As described above, the rotation axis AX5 of the drive shaft 25b of the drive lever 25 and the rotation axis AX2 of the spindle shaft 26b of the spindle lever 26 both extend horizontally in the vehicle length direction. In other words, the rotation axis AX5 of the drive shaft 25b of the drive lever 25 and the rotation axis AX2 of the spindle shaft 26b of the spindle lever 26 extend in the same direction. Also, with reference to Figure 10, the rotation axis AX5 of the drive shaft 25b of the drive lever 25 and the rotation axis AX2 of the spindle shaft 26b of the spindle lever 26 are disposed at positions that are eccentric to each other when viewed from the direction in which these axes AX2 and AX5 extend.

[0029] 8, a groove 31 is provided in the arm 26a of the spindle lever 26 on the side opposite to the spindle shaft 26b so as to face the arm 25a of the drive lever 25. In this embodiment, the groove 31 has a bottom, but may also penetrate the arm 26a in the thickness direction. An operating portion 25c (see also FIG. 9) is inserted into the groove 31.

[0030] The groove 31 will now be described.

[0031] 10, the groove 31 has a linear portion (operation groove portion) 31a extending in a direction away from the drive shaft 25b, and an arc-shaped portion (lock groove portion) 31b provided in communication with the linear portion 31a. The operating portion 25c abuts against a groove side wall (operation receiving portion) 31c of the groove 31.

[0032] When the operating portion 25c abuts against a pair of opposing groove side walls 31d, 31e of the groove side wall 31c in the linear portion 31, the spindle lever 26 rotates around the axis AX2, centered on the spindle shaft 26b, in a direction corresponding to the direction of rotation of the drive lever 25 around the axis AX5, centered on the drive shaft 25b. Depending on the direction of rotation of the spindle lever 26, the link mechanism 7 operates, and the lid 6 moves toward the fully open position or the fully closed position.

[0033] Of the side walls 31d, 31e of the straight portion 31, when the operating portion 25c abuts against the side wall 31d (opening operating portion) located on the inner side in Figure 10, i.e., the side closest to the drive shaft 25b (axis AX5) and the spindle shaft 26b (axis AX2), the lid 6 moves toward the fully open position due to the rotation of the spindle 26 and the accompanying operation of the link mechanism 7.

[0034] For example, when the lid 6 is in the fully closed position but in the unlocked state, i.e., when the drive lever 25 is at a rotation angle position where the operating portion 25c is located at the end of the linear portion 31 on the side of the arc-shaped portion 31b (State 2 in FIG. 11), if the drive lever 25 rotates clockwise (opening drive direction) in FIGS. 10 and 11, the operating portion 25c abuts against and presses against the side wall 31d, causing the spindle lever 26 to also rotate clockwise (opening actuation direction) in FIGS. 10 and 11. As the spindle lever 26 rotates, the first arm 11b of the link mechanism 7 rotates clockwise in FIGS. 10 and 11 around the spindle shaft 26b, and this rotation operates the link mechanism 7, causing the lid 6 to move toward the fully open position (progressing from State 2 to State 5 in FIG. 11).

[0035] 10, the operating portion 25c comes into contact with the side wall 31e (closing portion) located on the outer side of the side walls 31d, 31e of the linear portion 31, i.e., the side away from the drive shaft 25b (axis AX5) and the spindle shaft 26b (axis AX2), causing the rotation of the spindle 26 and the accompanying operation of the link mechanism 7 to move the lid 6 toward the fully closed position. The side wall 31e is linear when viewed in the direction in which the axes AX2, AX5 extend.

[0036] For example, when the lid 6 is in the fully open position (state 5 in FIG. 11) and the drive lever 25 rotates counterclockwise (closing drive direction) in FIGS. 10 and 11, the operating portion 25c abuts against and presses the side wall 31e, causing the spindle lever 26 to also rotate counterclockwise (closing actuation direction) in FIGS. 10 and 11. As the spindle lever 26 rotates, the first arm portion 11b of the link mechanism 7 rotates counterclockwise in FIGS. 10 and 11 around the spindle shaft 26b, and this rotation operates the link mechanism 7, causing the lid 6 to move toward the fully closed position (progressing from state 5 to state 2 in FIG. 11).

[0037] 10, the outer side of the side walls 31f, 31g of the arc-shaped portion 31b, i.e., the side wall 31g (locking portion) located on the side away from the drive shaft 25b (axis AX5) and the spindle shaft 26b (axis AX2), comes into contact with the operating portion 25c, thereby locking the lid 6 in the fully closed position. The side wall 31g is arc-shaped when viewed from the direction in which the axes AX2, AX5 extend. In this embodiment, the center C of the arc of the side wall 31g is shifted from the rotation axis AX5 of the drive shaft 25b toward the rotation axis AX2 of the spindle shaft 26b.

[0038] When the lid 6 is in the fully closed position and locked (state 1 in FIGS. 10 and 11 ), the rotational angle position of the drive lever 25 about the axis AX5 is set so that the operating portion 25c is located at the end of the arc-shaped portion 31b of the groove 31. In this state, when an external force acts on the lid 6 to move it to the fully open position (e.g., due to an attempt to pry the lid 6 open manually or vibration), the external force is transmitted to the spindle lever 26 via the link mechanism 7, and a rotational torque indicated by the arrow RT in the figures (a rotational torque that urges the spindle lever 26 in the opening operation direction) acts on the spindle lever 26. This rotational torque 26 is transmitted to the drive lever 25 via the side wall 31g of the groove 31. In other words, when an external force acts on the lid 6 to move it to the fully open position, the spindle lever 26 and the drive lever 25 form a kind of groove cam, with the former functioning as a driver and the latter functioning as a follower.

[0039] A force FT is transmitted from the side wall 31g (spindle lever 26 side) to the operating portion 25c (drive lever 25 side) by the rotational torque RT acting on the spindle lever 26, and is a force directed from a contact point CP between the side wall 31g and the operating portion 25c toward the center C of the arc. This force FT is resolved into a component force FT1 directed from the contact point CP toward the axis AX5 of rotation of the drive shaft 25b, and a component force FT2, which is a force in the tangential direction of the arc 31h formed by the side wall 31g2 at the contact point CP. The former component force FT1 does not urge the drive lever 25 to rotate around the drive shaft 25b, but the latter component force FT2 urges the drive lever 25 to rotate around the drive shaft 25b. As described above, the rotation axis AX5 of the drive shaft 25b and the rotation axis AX2 of the spindle shaft 26b are eccentric to each other, and the arc center C of the side wall 31 is offset from the rotation axis AX5 of the drive shaft 25b toward the rotation axis AX2 of the spindle shaft 26b. Due to the positioning of the axes AX2, AX5, and the arc center C, the component force FT2 biases the drive lever 25 to rotate counterclockwise (in FIG. 10 ) around the drive shaft 25b. Rotation of the drive lever 25 due to this bias is prevented by abutting against the stopper 24c. Thus, even if an external force acts on the lid 6 to move it to the fully open position, rotation of the drive lever 25 in the open drive direction is prevented, and rotation of the drive lever 25 in the opposite closing drive direction is prevented by the stopper 24c. As a result, even if an external force acts on the lid 6 to move it to the fully open position, the lid 6 remains in the fully closed position, i.e., locked.

[0040] As described above, the locking of the lid 6 in the fully closed position is achieved by two members, the drive lever 25 and the spindle lever 26, and there is no need to provide a lock lever for locking the lid 6 or a drive mechanism for driving it. Therefore, according to the lid opening and closing device 1 of this embodiment, it is possible to lock the lid 6 while suppressing an increase in the number of parts and complexity, and it is possible to suppress an increase in the cost of manufacturing the lid opening and closing device 1.

[0041] 10, the center C of the arc 31h of the side wall 31g may be aligned with the axis AX5 of rotation of the drive lever 25 about the drive shaft 25b. In this configuration, when an external force attempting to move the lid 6 to the fully open position generates a rotational torque RT acting on the spindle lever 26, the force FT applied from the side wall 31g to the operating portion 25c is a force directed from the contact point CP toward the axis AX5. In other words, in this case, the force FT does not have a component T2 that rotates the drive lever 25. Therefore, even if the center C of the arc 31h of the side wall 31g is aligned with the axis AX5 of rotation of the drive lever 25 about the drive shaft 25b, the lid 6 can be maintained in the fully closed position, i.e., in a locked state, against an external force attempting to move the lid 6 to the fully open position.

[0042] 2 and 6, the emergency mechanism 9 includes an emergency lever 41 and a wire 42, which is a pulling member that can be pulled from inside the vehicle. The emergency lever 41 includes a shaft 41a that is rotatable about an axis AX6 and located outside the arm 26a of the spindle lever 26, and two arms 41b and 41c extending from the shaft 41a. One arm 41b is positioned adjacent to the arm 25a of the drive lever 25 on the closing drive direction side. The other arm 41c is connected to the wire 42. For example, if the onboard battery supplying power to the electric motor 21 is over-discharged, pulling the wire 42 rotates the emergency lever 41 about the axis AX6. As a result of this rotation, the arm 41b presses the arm 25a of the drive lever 25 so that the drive lever 25 rotates in the opening drive direction. As a result, the spindle lever 26 rotates in the opening drive direction, and the lid 6 moves toward the fully open position.

[0043] 12 to 14 show a lid opening / closing device according to a modified example. The lid 6 is in the fully open position in FIG. 12, moves through the half-open position in FIG. 13, and then moves to the fully closed position in FIG. 14. In FIGS. 12 and 13, the arrow DT indicates the drive torque applied from the actuator 22 to the drive lever 25 when the lid 6 moves to the fully closed position. In this modified example, the groove 31 is composed only of the linear portion 31a, and the end of the side wall 31e on the spindle shaft 26b side serves as the locking portion, with the remaining portion of the side wall 31e serving as the closing portion. When an external force acts on the lid 6 in the fully closed position in FIG. 14 to move it to the fully open position, the external force is transmitted to the spindle lever 26 via the link mechanism 7, and a rotational torque RT (a rotational torque that urges the spindle lever 26 in the opening direction) acts on the lid 6. However, in the state shown in Figure 14, when the spindle lever 26 is used as the driving lever and the drive lever 25 is used as the follower cam mechanism, the pressure angle δ, that is, the angle formed by the normal direction of the side wall 31d (cam surface) of the groove 31 and the rotation direction of the operating part 25c (follower) of the drive lever 25, is 90 degrees. In other words, the force FT applied from the side wall 31e to the operating part 25c is a force directed from the contact point CP toward the axis AX5, so the drive lever 25 does not rotate and the lid 6 is maintained in the locked state.
