Description

Vehicle door opening adjustment device

The present invention relates to an opening adjustment device for a vehicle door.

Conventionally, for example, a device described in Patent Document 1 is known as an opening adjustment device for a vehicle door. The opening adjustment device for a vehicle door includes a check link that is rotatably connected to a vehicle body, and a door check that is fixed in the door and through which the check link is inserted. When the door is opened, the stopper portion of the check link comes into contact with the door check, thereby restricting the door at the fully opened position.

Also, the opening adjustment device for a vehicle door has an opening adjustment block that is rotatably connected to a door check. When the position of the opening adjustment block is switched so as to block the movement path of the check link stopper, the check link stopper abuts the opening adjustment block during the opening of the door, thereby causing the door to Regulate with half-open position. Note that the position of the opening adjustment block is switched by an operating device provided at a portion of the door inside the vehicle.

Therefore, for example, when a user gets on and off from the own vehicle, if another vehicle is parked next to the own vehicle and the space around the door is narrow, the operation device is set to restrict the door with a half-open position. The door that is opened too much does not hit the adjacent vehicle, and smooth boarding and exiting is possible.

JP 2016-125207 A

By the way, in Patent Document 1, when the user opens the door from the inside of the vehicle and gets off the vehicle with the operation device set to restrict the door with the half-opening degree, and then opens the door from the outside of the vehicle, If the vehicle is running away and there is sufficient space around the door, this user may forget to set the door restriction at the half-open position and open the door vigorously. In this case, the door is regulated with a narrow opening degree with respect to the user's sense of opening the door, which gives the user a sense of incongruity as if the door was caught.

It is an object of the present invention to provide an opening adjustment device for a vehicle door that can be activated when the door is opened from the inside of the vehicle and disabled when the door is opened from the outside of the vehicle. It is to provide.

In one aspect of the present invention, an opening adjustment device for a vehicle door includes a check link having a stopper portion and rotatably connected to a vehicle body, and the check link fixed to the vehicle door. A door check for restricting the door at a fully open position by the stopper being brought into contact with the opening operation of the door, and a separation position for releasing the movement locus of the stopper accompanying the opening operation of the door; The door is movably provided between engagement positions that block the movement locus, and the stopper portion comes into contact with the opening operation of the door when the door is in the engagement position, so that the door is opened at a half-open position. As the opening adjustment member to be controlled and the inside door handle are operated, the opening adjustment member is moved from the disengagement position to the engagement position, and the door is subsequently opened. And a driving member for moving into the disengaged position from the engaging position to the opening adjusting member by the operation.

(First embodiment)
Hereinafter, a first embodiment of an opening adjusting device for a vehicle door will be described.
As shown in FIG. 1, an opening 2 for getting on and off is formed in a side portion of a vehicle body 1. A door 4 is rotatably connected to a front edge 2a of the opening 2 by a pair of door hinges 3 arranged in parallel in the vehicle height direction. The door 4 operates to open and close the opening 2 by rotating in one direction and the other direction around the door hinge 3.

In the door 4, a door lock device 5 is provided along the rear end. The door lock device 5 is engaged with a striker ST provided on the body 1 to hold the door 4 in a closed state with respect to the body 1. The door 4 is provided with an inside door handle 6 so as to be exposed to the inside of the vehicle, and is provided with an outside door handle 7 so as to be exposed to the outside of the vehicle. When each of the inside door handle 6 and the outside door handle 7 is operated, the operation force is transmitted to the door lock device 5, thereby releasing the holding of the door 4 in the closed state by the door lock device 5. .

A base end portion of a substantially long check link 11 made of, for example, a metal rod is coupled to the edge portion 2a so as to be rotatable around an axis extending in the vehicle height direction in accordance with the opening / closing direction of the door 4. ing. On the other hand, a door check 16 is fastened to the door 4. The front end portion of the check link 11 enters the door 4 and is inserted into the door check 16 so as to be movable in the longitudinal direction. The check link 11 and the door check 16 form a door check mechanism 10.

As shown in FIGS. 2A and 2B, the check link 11 has its longitudinal length with respect to the door check 16 (door 4) while swinging around its base end according to the opening / closing operation of the door 4. Move relative to the direction. For example, when the door 4 is opened, the check link 11 moves through the door check 16 in the direction of retracting from the door 4. On the contrary, when the door 4 is closed, the check link 11 moves in the direction of entering the door 4 through the door check 16. That is, the relative position of the check link 11 to the door check 16 uniquely corresponds to the opening / closing position (opening) of the door 4. Specifically, as the length of the check link 11 protruding from the door check 16 into the door 4 is longer, the opening degree is smaller. Conversely, as the length is shorter, the opening degree is larger.

The check link 11 is formed with a plurality of upper and lower trough portions 11a at intervals in the longitudinal direction, and the door check 16 has one of the pair of trough portions 11a sandwiched between the check links 11. A pair of rollers (not shown in the figure) that regulate the movement in the longitudinal direction slightly is incorporated. Therefore, when the movement of the check link 11 in the longitudinal direction is slightly restricted by the door check 16, the door 4 is slightly held at the corresponding opening / closing position (opening).

Further, a plate-like stopper portion 12 that is wider than the check link 11 in the width direction and the height direction of the vehicle is fixed to the front end portion of the check link 11. As shown in FIG. 2 (aA), the stopper portion 12 contacts the door check 16 when the check link 11 tries to retract from the door 4 through the door check 16 as the door 4 is opened. In contact therewith, the further opening operation of the door 4 is restricted. The opening degree of the door 4 at this time corresponds to a fully opened opening degree. In other words, the door check 16 regulates the door 4 at the fully open position by the stopper portion 12 coming into contact with the door check 16 as the door 4 is opened.

The opening adjustment member 17 made of, for example, a metal plate is connected to the upper end portion of the door check 16 so as to be rotatable around an axis O1 extending in the vehicle width direction. The opening adjusting member 17 includes a pair of substantially L-shaped side walls 17a that sandwich the check link 11 in the vehicle width direction, and a lid wall 17b that connects the upper edges of both side walls 17a in the vehicle width direction. Have one. The front end surfaces of the side walls 17a that face the door check 16 form a first contact portion 18 that comes into contact with the door check 16 in close contact with the door check 16 as it rotates clockwise around the axis O1.

When the first contact portion 18 is in contact with the door check 16 as shown in FIG. 2B, the lid wall 17b is positioned above the check link 11, so that the opening adjustment member 17 is There is no interference with the check link 11. At this time, the front end surface of the opening adjustment member 17 (both side walls 17a and lid wall 17b) that is separated from the door check 16 forms a second contact portion 19 that faces the stopper portion 12 in the moving direction of the check link 11. To do. Accordingly, the stopper portion 12 abuts on the second abutment portion 19 when the check link 11 attempts to retract from the door 4 through the door check 16 as the door 4 is opened. Further opening operation of the door 4 is restricted. In other words, the opening adjustment member 17 regulates the door 4 with a predetermined half-opening opening degree by the stopper portion 12 coming into contact with the second contact portion 19 as the door 4 is opened.

If at least a part of the second contact portion 19 blocks the movement locus of the stopper portion 12 associated with the opening operation of the door 4, the stopper portion 12 is used for adjusting the opening degree via the second contact portion 19. The member 17 is pressed. As a result, the opening adjusting member 17 rotates clockwise around the axis O <b> 1 and the first contact portion 18 contacts the door check 16. Therefore, the rotation of the opening adjusting member 17 is restricted. In other words, if at least a part of the second contact portion 19 blocks the movement locus of the stopper portion 12 that accompanies the opening operation of the door 4, the door 4 is regulated by the half-opening degree in the above-described manner. As shown in FIG. 2B, the rotation position of the opening adjusting member 17 when at least a part of the second contact portion 19 blocks the movement locus of the stopper portion 12 accompanying the opening operation of the door 4 It's called the "position." On the other hand, as shown in FIG. 2 (a), the second abutting portion 19 does not block the movement locus of the stopper portion 12 that accompanies the opening operation of the door 4, that is, a predetermined opening degree adjusting member 17 for opening is opened. The rotation position is referred to as “detachment position”. The opening adjusting member 17 is urged so as to rotate toward the disengagement position by a coil spring SP as an urging member wound around the axis O1, for example.

Next, a structure for rotating (moving) the opening adjustment member 17 between the disengagement position and the engagement position will be described.
As shown in FIG. 3, the opening degree adjusting member 17 is provided with a substantially arm-shaped connecting piece 17 c extending upward from its upper end. In the door 4, an operating lever 21 is rotatably connected as an operating member around an axis O <b> 2 extending in the vehicle width direction obliquely below the door check 16. The operation lever 21 has a substantially L shape having a pair of substantially arm-shaped

lever protrusions

22 and 23 extending in different radial directions around the axis O2. A substantially columnar knob 22 a that protrudes to the vehicle inner side is projected from a distal end portion of the lever projecting piece 22 in a substantially arc-shaped guide groove 4 a centering on an axis O <b> 2 formed in the door 4. A substantially arcuate guide groove 23 a that protrudes toward the lever protrusion 22 is formed at the tip of the lever protrusion 23. A substantially cylindrical engaging pin 24 is inserted into and prevented from detaching from the guide groove 23a along the longitudinal direction thereof. Note that the engagement pin 24 is held by a suitable guide member (not shown) so as to be positioned at the tip of the guide groove 23a that is separated from the axis O2, that is, at the end far from the axis O2 of both ends of the guide groove 23a. Has been.

In the door 4, an input lever 26 is rotatably connected around an axis O3 extending in the vehicle width direction above the axis O2. The input lever 26 has a pair of substantially arm-shaped

lever protrusions

27 and 28 extending in opposite radial directions about the axis O3. The lever protrusion 28 is provided with a substantially triangular engagement protrusion 28a that protrudes counterclockwise in the figure around the axis O3. The input lever 26 is urged in a clockwise rotating direction in the drawing by a torsion spring wound around the axis O3, and the lever protruding piece 28 is in contact with a stopper 29 provided on the door 4. . Thus, the input lever 26 is held at a predetermined initial rotation position.

Here, the input lever 26 is connected to the inside door handle 6 via the wire W1 at the lever protrusion 27 and is connected to the door lock device 5 via the wire W2 at the lever protrusion 28. When the inside door handle 6 is operated when the input lever 26 is in the initial rotation position, the operating force is transmitted to the lever protrusion 27 via the wire W1. As a result, the input lever 26 rotates counterclockwise from the initial rotation position. As a result, the operating force of the inside door handle 6 is transmitted from the lever projecting piece 28 to the door lock device 5 via the wire W2, and the holding of the door 4 in the closed state by the door lock device 5 is released.

Note that when the rotation position of the operation lever 21 is in the non-operation position indicated by the two-dot chain line in the figure, the engagement pin 24 is out of the rotation locus of the input lever 26 (engagement protrusion 28a). At this time, a transmission lever 31 described later is released from the input lever 26. On the other hand, when the operating lever 21 is rotated clockwise from the non-operating position to the operating position indicated by the solid line in the drawing, the guide groove 23a extends in the circumferential direction around the axis O3, and The combination pin 24 blocks the rotation locus of the input lever 26 (engagement protrusion 28a). Therefore, when the input lever 26 rotates counterclockwise in the drawing from the initial rotation position, the engagement pin 24 is pressed by the engagement protrusion 28a and moves along the guide groove 23a.

Furthermore, a transmission lever 31 is connected to the door 4 so as to be rotatable coaxially with the input lever 26. The transmission lever 31 has a substantially fan-shaped lever protrusion 32 extending in the radial direction downward in the figure centered on the axis O3, and a substantially claw-shaped stopper piece 33 extending in the radial direction toward the upper left in the figure. have. The lever projecting piece 32 has a first end surface on the side preceding the illustrated counterclockwise direction and a second end surface on the side preceding the illustrated clockwise direction. The first end surface extends in parallel with the radial direction centered on the axis O3 to form the cam surface 32a, and the second end surface extends in the radial direction centered on the axis O3 to form the engaged surface 32b. To do. The outer peripheral surface of the lever protruding piece 32 extends in the circumferential direction around the axis O3 to form a holding surface 32c. The transmission lever 31 is urged in a clockwise rotating direction by a torsion spring wound around the axis O3, and the stopper piece 33 abuts against a stopper 34 provided on the door 4. Yes. As a result, the transmission lever 31 is held at a predetermined initial position.

At this time, the engaged surface 32b of the lever protrusion 32 faces the engaging protrusion 28a of the input lever 26 at the initial rotation position in the circumferential direction centering on the axis O3. When the operation lever 21 rotates from the non-operating position toward the operating position, the engaging pin 24 enters between the engaged surface 32b and the engaging protrusion 28a. Therefore, when the operation lever 21 is in the operating position, when the input lever 26 is rotated counterclockwise from the initial rotation position in accordance with the operation of the inside door handle 6, the engagement pin pressed by the engagement protrusion 28a. 24 moves along the guide groove 23a. At this time, when the engagement pin 24 presses the engaged surface 32b, the transmission lever 31 rotates counterclockwise in the drawing from the initial position.

In the door 4, a knock mechanism 40 having a center line extending in the radial direction centering on the axis O3 and extending downward in the figure is provided. The knock mechanism 40 includes a cylindrical holder 41 that opens along the center line, and a linear movement lever 46 that is slidably inserted into the holder 41.

One end of a rod 51 made of, for example, a metal rod extending along the center line is fixed to the distal end of the linear motion lever 46 that is separated from the axis O3. The other end of the rod 51 is fixed to the connecting piece 17 c of the opening adjusting member 17. The rod 51 forms a switching mechanism together with the knock mechanism 40. As described above, the opening adjustment member 17 is biased by the coil spring SP so as to rotate toward the disengagement position. Accordingly, the direct acting lever 46 is biased by the coil spring SP in the direction of moving from the inside of the holder 41 toward the axis O3 via the rod 51.

Note that the movement is restricted by the tip of the linear movement lever 46 coming into contact with the transmission lever 31. Further, each time the linear movement lever 46 moves away from the axis O3 against the urging force of the coil spring SP, the linear movement lever 46 is switched between a locked state held at the position and a unlocked state where the holding is released. It is configured. That is, the linear movement lever 46 is urged by the coil spring SP and is in contact with the transmission lever 31 when in the unlocked state.

Here, the linear movement lever 46 in the unlocked state is in contact with the transmission lever 31 in the initial position at the proximal end of the cam surface 32a. At this time, the opening adjusting member 17 connected to the linear motion lever 46 via the rod 51 is held at the disengagement position shown in FIG. In this state, for example, when the transmission lever 31 rotates as described above in accordance with the operation of the inside door handle 6 when getting off, the cam surface 32a presses the tip of the linear movement lever 46 as shown by the change to FIG. The linear movement lever 46 moves together with the rod 51 so as to be separated from the axis O3 against the urging force of the coil spring SP. At this time, the rod 51 pulls the connecting piece 17 c of the opening adjustment member 17, and the opening adjustment member 17 reaches the engagement position in a state where the first contact portion 18 contacts the door check 16. At the same time, the direct acting lever 46 is in a ready state for switching to the locked state. The linear movement lever 46 contacts the transmission lever 31 at the tip of the cam surface 32a (the boundary position of the holding surface 32c). At this stage, the release by the door lock device 5 is not completed. This is to prevent the door 4 from being opened prior to reaching the engagement position of the opening adjusting member 17.

When the inside door handle 6 is further operated, the operating force is transmitted to the door lock device 5 as described above, as shown by the change in FIG. 5, and the door 4 is closed by the door lock device 5. Holding is released. At this time, although the transmission lever 31 further rotates, the holding surface 32 c slides with respect to the linear movement lever 46. Accordingly, the linear movement lever 46 maintains the current position (prepared state).

Thereafter, when the operating force of the inside door handle 6 is released, the input lever 26 biased by the torsion spring returns to the initial rotation position and is also biased by the torsion spring as shown by the change to FIG. The transmission lever 31 returns to the initial position. As a result, the linear movement lever 46 is released from the transmission lever 31. When the linear movement lever 46 is released from the transmission lever 31, it is biased by the coil spring SP and moves slightly toward the axis O3. At this time, the direct acting lever 46 is switched from the above-mentioned preparation state to the locked state. As the linear movement lever 46 moves, the rod 51 pushes the connecting piece 17c of the opening adjustment member 17, and the opening adjustment member 17 is slightly rotated around the axis O1 within a range in which it is within the engagement position. To do.

Thereafter, when the door 4 is opened, the stopper portion 12 of the check link 11 presses the second contact portion 19 of the opening adjusting member 17. As a result, as shown in the change to FIG. 7, the opening adjusting member 17 rotates around the axis O <b> 1 until the first contact portion 18 contacts the door check 16. At this time, the opening adjusting member 17 pushes the direct acting lever 46 through the rod 51, and the direct acting lever 46 moves slightly so as to be separated from the axis O3 against the urging force of the coil spring SP. The linear movement lever 46 is switched to the unlocked state, and the holding at the position is released. That is, the holding of the opening adjusting member 17 at the engaged position is released by the linear movement lever 46 in the unlocked state.

Thereafter, when the door 4 is closed, the stopper portion 12 of the check link 11 releases the second contact portion 19 of the opening adjusting member 17. For this reason, the linear movement lever 46 is moved by being biased by the coil spring SP until it contacts the transmission lever 31 toward the axis O3, and the rod 51 pushes the connecting piece 17c of the opening adjusting member 17 to open it. The degree adjusting member 17 rotates around the axis O1 and reaches the separation position (see FIG. 3). Therefore, when the inside door handle 6 is not operated thereafter, that is, when the door 4 is opened from the outside of the vehicle by operating the outside door handle 7, the opening adjusting member 17 remains in the detached position. Therefore, the door 4 is not restricted by the half-opening degree.

The input lever 26, the transmission lever 31, the knock mechanism 40, and the rod 51 form the drive member 20 together with the coil spring SP.
Next, the structure of the knock mechanism 40 will be described.

As shown in FIG. 8, the tip of the holder 41 that is separated from the axis O3, that is, the end far from the axis O3 among the both ends of the holder 41 is trapezoidal in the middle in the short direction DS. The first guide wall 42 protrudes from the first side (the near side perpendicular to the paper surface). The first guide wall 42 has a substantially triangular shape that is sharpened toward the axis O3, and a surface on one side in the short-side direction DS (the left side in the figure, hereinafter referred to as “first side D1”) is an axis line. A guide surface 42a is formed so as to be displaced toward the first side D1 as the distance from O3 increases. Further, the surface on the other side in the short direction DS of the first guide wall 42 (right side in the figure, hereinafter referred to as “second side D2”) is in a direction perpendicular to the short direction DS (that is, the longitudinal direction of the holder 41). An extending guide surface 42b is formed.

In addition, at the tip portion of the holder 41 that is separated from the axis O3, a substantially bifurcated trapezoidal second guide wall adjacent to the first guide wall 42 at a position between the first guide wall 42 and the axis O3. 43 protrudes from the first side (the front side perpendicular to the paper surface). A pair of

guide pieces

43a and 43b is provided at the tip of the second guide wall 43 facing the first guide wall 42 toward the first guide wall 42 so as to sandwich the first guide wall 42 in the short direction DS. Is protruding. A guide wall 43c extending in the short direction DS is formed between the

guide pieces

43a and 43b in the short direction DS. The second guide wall 43 is inclined so as to be displaced to the first side D1 as it is separated from the axis O3, and is displaced to the first side D1 as it is separated from the axis O3. And a guide surface 43e that is inclined and connected to the guide piece 43b. Both

guide surfaces

43d, 43e are connected to each other at the ends near the axis O3, and the inclination angle of the guide surface 43e is steeper than the inclination angle of the guide surface 43d with respect to the short direction DS. . In other words, the magnitude of the displacement of the guide surface 43d toward the first side D1 following the separation from the axis O3 is larger than that of the guide surface 43e. In addition, the connection part 43f of both the guide surfaces 43d and 43e is arrange | positioned near the 2nd side D2 in the transversal direction DS.

On the other hand, a spring 47 is arranged closer to the axis O3 than the second guide wall 43. A first end of the spring 47 is fixed to the linear movement lever 46, and a second end of the spring 47 is fixed to a switching piece 48 made of, for example, a metal plate. The switching piece 48 is normally biased by a spring 47 so as to extend toward the first guide wall 42 and the like in a direction perpendicular to the short direction DS (that is, the longitudinal direction of the linear movement lever 46). The switching piece 48 is supported so as to be swingable in the short direction DS about the second end of the spring 47 as the spring 47 is elastically deformed.

The switching piece 48 includes an arm portion 48a extending in the longitudinal direction of the linear movement lever 46 on the first side (the front side orthogonal to the paper surface) of the first and

second guide walls

42, 43 and the distal end of the arm portion 48a. It has a substantially square engaging piece 48b protruding to the second side (the back side orthogonal to the paper surface). The first and

second guide walls

42 and 43 do not block the movement trajectory of the arm portion 48a, that is, open, and block the movement trajectory of the engagement piece 48b. That is, the switching piece 48 engages with the first and

second guide walls

42 and 43 at the engaging piece 48 b as the linear movement lever 46 moves.

Here, as shown in FIG. 8A, in the state (corresponding to FIG. 3) in which the linear movement lever 46 is urged by the coil spring SP and moves from the holder 41 toward the axis O3, the switching piece 48 is used. Is spaced from the second guide wall 43 toward the axis O3 and extends in the longitudinal direction of the linear movement lever 46 so as to face the second guide wall 43 near the second side D2 of the second guide wall 43. Yes. Therefore, when the linear movement lever 46 moves away from the axis O3 against the urging force of the coil spring SP, the engagement piece 48b of the switching piece 48 is guided to the guide surface 43d of the second guide wall 43. Thus, the switching piece 48 rotates clockwise with the spring 47 as a fulcrum. When the engaging piece 48b reaches and passes through the guide piece 43a, the switching piece 48 is urged by the spring 47 and rotated counterclockwise as shown in the change to FIG. 8B. The engagement piece 48b is prevented from rotating by contacting the guide surface 42a (corresponding to FIGS. 4 and 5).

In this state, when the linear motion lever 46 is urged by the coil spring SP and moves from the inside of the holder 41 toward the axis O3, the engagement piece 48b is moved to the guide surface 42a as shown by the change in FIG. 8C. The guide wall 43c of the second guide wall 43 is reached while being guided. At this time, the switching piece 48 is biased by the spring 47, thereby moving the guide wall 43c until the engaging piece 48b reaches the guide piece 43b. That is, the engagement piece 48b moves to the second side D2 from the first guide wall 42 (guide surface 42b). As a result, the linear movement lever 46 is switched to a locked state in which the linear movement lever 46 is held at the position (corresponding to FIG. 6).

Subsequently, when the linear movement lever 46 moves away from the axis O3 against the urging force of the coil spring SP, the engagement piece 48b of the switching piece 48 is moved to the first side by the guide surface 42b of the first guide wall 42. It is guided to the guide piece 43b of the second guide wall 43 in a state where the movement to D1 is restricted. When the engaging piece 48b passes through the guide piece 43b, the switching piece 48 is urged by the spring 47 and rotated counterclockwise as shown in FIG. It will be in a state extending in the direction. Thereby, the engagement piece 48b moves to the second side D2 from the guide piece 43b, so that the linear movement lever 46 is switched to the unlocked state in which the holding at the position is released (corresponding to FIG. 7). At this time, the direct acting lever 46 is urged by the coil spring SP to be movable from the holder 41 toward the axis O3.

As described above, the regulation of the door 4 shown in FIGS. 3 to 7 is realized based on the operation of FIGS. 8A to 8D by the knock mechanism 40.
Next, the effect of this embodiment will be described.

(1) In this embodiment, when the inside door handle 6 is operated, the opening adjusting member 17 is moved from the disengaged position to the engaged position by the drive member 20. As a result, when the door 4 is subsequently opened, the stopper portion 12 abuts on the opening adjustment member 17 so that the door 4 is regulated at the half-opening opening. As described above, the restriction of the door 4 at the half-open position can be validated when the door 4 is opened from the inside of the vehicle. On the other hand, when the door 4 is closed through the opening operation, the opening adjusting member 17 is moved from the engagement position to the disengagement position by the drive member 20. Accordingly, when the inside door handle 6 is not operated, that is, when the door 4 is opened from the outside of the vehicle, the opening adjustment member 17 remains in the detached position. Therefore, it is possible to invalidate the restriction of the door 4 at the half-open position. Normally, when the user gets on the vehicle, the user can visually check the surroundings of the door 4, so that the restriction of the door 4 at the half-open position that may give the user a sense of incongruity as if the door 4 is caught is invalidated. The discomfort at the time of boarding can be eliminated.

(2) In the present embodiment, the operation lever 21 that selectively switches between the operation and non-operation of the drive member 20 in accordance with the operation of the inside door handle 6 is provided at a portion of the door 4 on the vehicle inner side. Therefore, for example, when there is sufficient space around the door 4, the drive member 20 is switched so that the drive member 20 is not activated even if the inside door handle 6 is operated by the operation lever 21. Even when the door is opened, it is possible to eliminate the restriction of the door 4 by the half-opening degree. Therefore, it is possible to get off more smoothly.

(3) In the present embodiment, for example, when the operation lever 21 is in the operating position, when the input lever 26 is rotated in accordance with the operation of the inside door handle 6, the transmission lever 31 is moved via the operation lever 21 (engagement pin 24). Then, it is pressed by the input lever 26 and rotates. The opening adjusting member 17 is moved to the engagement position by the knock mechanism 40 and the rod 51 and is held at the engagement position. Therefore, when the door 4 is subsequently opened, the stopper portion 12 comes into contact with the opening adjustment member 17 so that the door 4 is regulated by the half-opening opening. At this time, the holding of the opening adjusting member 17 by the knock mechanism 40 and the rod 51 at the engagement position is released. Accordingly, when the door 4 is subsequently closed, the opening adjusting member 17 is released from the stopper portion 12 and is urged by the coil spring SP to move to the disengagement position. Accordingly, when the inside door handle 6 is not operated, that is, when the door 4 is opened from the outside of the vehicle, the opening adjustment member 17 remains in the detached position. Therefore, the door 4 can be opened without being restricted by the half-opening degree. As described above, the restriction setting of the door 4 at the half-opening degree can be realized only by the mechanical configuration of the operation lever 21 and the like (the driving member 20).

(4) In the present embodiment, the opening adjusting member 17 is operated so as to regulate the door 4 with a half-opening opening by using the inside door handle 6 used when getting off the vehicle. Therefore, convenience can be improved.

(5) In the present embodiment, the movement of the opening adjusting member 17 to the engagement position is completed prior to the release of the door lock device 5 accompanying the operation of the inside door handle 6. For this reason, the door 4 can be regulated more stably at the half-open position.

(6) In this embodiment, if at least a part of the second contact part 19 is in an engagement position that blocks the movement locus of the stopper part 12, the door 4 can be regulated with a half-opening degree. Therefore, for example, it is possible to absorb the component variation and assembly variation of the check link 11 and more reliably regulate the door 4 with the half-opening degree.

(Second Embodiment)
Hereinafter, a second embodiment of the vehicle door opening degree adjusting device will be described. In addition, in 2nd Embodiment, it has changed so that the movement of the member for opening degree adjustment of 1st Embodiment may be electrically performed. Detailed description of similar parts is omitted.

As shown in FIG. 9, for example, a door ECU (Electronic Control Unit) 60 as a control unit installed in the door 4 is configured mainly by a micro controller (MCU), for example, and is also installed in the door 4. It is electrically connected to an actuator 61 as an electric drive source. The actuator 61 is mainly composed of an electric motor, and is mechanically linked to an opening adjustment member 62 according to the opening adjustment member 17. The opening adjustment member 62 is basically arranged at the disengagement position.

Further, the door ECU 60 is electrically connected to a handle switch 63 that outputs a detection signal Si1 indicating a detection result of the operation of the inside door handle 6. Further, the door ECU 60 is electrically connected to a door opening sensor 64 that outputs a detection signal Si2 that represents a detection result of the opening of the door 4. The door ECU 60, the actuator 61, the handle switch 63 and the door opening sensor 64 constitute a drive member 70.

Further, the door ECU 60 is electrically connected to an operation switch 65 that is provided at a portion of the door 4 on the vehicle inner side and outputs an operation signal Si3 that represents a selection result of operation or non-operation of the drive member 70. The door ECU 60 moves the opening adjustment member 62 between the disengagement position and the engagement position based on the detection signal Si1 of the handle switch 63, the detection signal Si2 of the door opening sensor 64, and the operation signal Si3 of the operation switch 65. Accordingly, the actuator 61 is driven and controlled.

Next, the drive control mode of the actuator 61 by the door ECU 60 will be described.
As shown in FIG. 10, when the processing shifts to this routine, the door ECU 60 determines whether or not the operation signal Si3 of the operation switch 65 is ON, that is, the operation signal Si3 that represents the selection result of the operation of the drive member 70. Is determined (step S1). Here, when it is determined that the operation signal Si3 of the operation switch 65 is off, that is, the operation switch 65 is outputting the operation signal Si3 indicating the selection result of the non-operation of the drive member 70, the door ECU 60 performs the process as it is. finish. On the other hand, when the operation signal Si3 of the operation switch 65 is turned on, that is, when it is determined that the operation switch 65 is outputting the operation signal Si3 indicating the selection result of the operation of the drive member 70, the door ECU 60 It is determined whether or not the operation signal Si3 is on, that is, whether or not the handle switch 63 outputs a detection signal Si1 that represents a detection result of the operation of the inside door handle 6 (step S2). If it is determined that the detection signal Si1 of the handle switch 63 is off, that is, the handle switch 63 does not output the detection signal Si1 indicating the detection result of the operation of the inside door handle 6, the door ECU 60 performs the processing as it is. finish.

On the other hand, when the detection signal Si1 of the handle switch 63 is turned on, that is, when it is determined that the handle switch 63 outputs the detection signal Si1 indicating the detection result of the operation of the inside door handle 6, the door ECU 60 adjusts the opening degree. The actuator 61 is driven and controlled to move the member 62 to the engagement position (step S3). Thereafter, the user releases the door lock device 5 and opens the door 4 to get off the vehicle. The door lock device 5 that is released in accordance with the operation of the inside door handle 6 may be directly connected to the inside door handle 6 via a wire.

The door ECU 60 determines whether or not the door 4 has reached a half-opening degree that is regulated by the opening-adjusting member 62 in accordance with the opening operation of the door 4, that is, the door opening sensor 64 indicates the detection result of the half-opening degree. It is determined whether or not a detection signal Si2 is output (step S4). The door ECU 60 waits for the door 4 to reach the half-opened position (YES in step S4), and whether or not the door 4 has been closed, that is, the door opening sensor 64 corresponds to the closing operation of the door 4. It is determined whether or not a detection signal Si2 representing the detection result is output (step S5). This is because the user can consider that the user has got off during the closing operation after the door 4 reaches the half-opening degree. In other words, in this state, unless the inside door handle 6 is operated, the subsequent opening operation of the door 4 is from the outside of the vehicle.

The door ECU 60 waits for the door 4 to close (YES in step S5), drives and controls the actuator 61 to move the opening adjusting member 62 to the disengagement position (step S6), and ends the process. To do.

As described above, when the opening adjustment member 62 is arranged, when the door 4 is subsequently opened from the outside of the vehicle, the door 4 can be opened without being restricted by the half-open opening.
As described above in detail, according to the present embodiment, the following effects can be obtained in addition to the effects (1) and (4) to (6) in the first embodiment.

(7) In the present embodiment, the operation of the inside door handle 6 is detected based on the detection signal Si1 of the handle switch 63. At this time, when the door ECU 60 drives and controls the actuator 61 so as to move the opening adjustment member 62 from the disengagement position to the engagement position, the stopper 12 adjusts the opening when the door 4 is subsequently opened. It abuts on the member 62 for use. Thereby, the door 4 is regulated by the half-opening opening degree. On the other hand, when the closing operation through the opening operation of the door 4 is detected based on the detection signal Si2 of the door opening sensor 64, the door ECU 60 operates the actuator to move the opening adjusting member 62 from the engagement position to the disengagement position. 61 is driven and controlled. Thereby, when the inside door handle 6 is not operated, that is, when the door 4 is opened from the outside of the vehicle, the opening adjusting member 62 remains in the disengaged position. Therefore, the door 4 can be opened without being restricted by the half-opening degree. In this way, the setting of the regulation of the door 4 at the half-opening degree can be realized by electrical control by the door ECU 60 or the like, and the mechanical structure can be further simplified.

(8) In the present embodiment, for example, when there is sufficient space around the door 4, the door 4 is opened from the inside of the vehicle by selecting the non-operation of the driving member 70 by the operation switch 65. The door 4 can be prevented from being restricted by the half-open position. Therefore, it is possible to get off more smoothly.

In addition, you may change the said embodiment as follows.
In the first embodiment, the amount of movement of the linear movement lever 46 by the operation of the inside door handle 6 (see FIGS. 4 and 5) is the movement of the linear movement lever 46 when the door 4 is regulated by a half-opening degree. It may be smaller than the amount (see FIG. 7). The amount of movement of the linear movement lever 46 by operating the inside door handle 6 prevents the engagement piece 48b of the switching piece 48 from getting over the guide piece 43b, that is, the linear movement lever 46 is not switched to the unlocked state. May be. In this case, once the restriction of the door 4 at the half-opening degree is set in accordance with the operation of the inside door handle 6, the linear movement lever 46 remains in the locked state as long as the operation of the inside door handle 6 is continued. The regulation of the door 4 is maintained. Thereby, convenience can be improved.

In the first embodiment, the linear movement lever 46 is urged to move toward the axis O3 using the coil spring SP of the opening adjusting member 17. Instead, a dedicated urging member that moves the linear movement lever 46 toward the axis O3 may be provided.

-In the said 1st Embodiment, the roller etc. which roll the cam surface 32a may be installed in the front-end | tip of the linear motion lever 46, and rotation of the transmission lever 31 etc. may be made smoother.
In the first embodiment, the knock mechanism 40 may be a rotary type mounted on, for example, a ballpoint pen.

In the first embodiment, the operation lever 21 that selectively switches between the operation and non-operation of the drive member 20 associated with the operation of the inside door handle 6 may be omitted. In this case, the input lever 26 and the transmission lever 31 may be rotated integrally.

In the second embodiment, any one of the movement from the disengagement position to the engagement position and the movement from the engagement position to the disengagement position of the opening adjustment member 62 is performed using an appropriate biasing force of the return spring. You may go.

In the second embodiment, the operation switch 65 that outputs the operation signal Si3 indicating the selection result of the operation and non-operation of the drive member 70 may be omitted. In this case, when the operation of the inside door handle 6 is detected based on the detection signal Si1 of the handle switch 63, the door ECU 60 causes the actuator 61 to move the opening adjustment member 62 from the disengagement position to the engagement position. Drive control may be performed.

In each of the above embodiments, the

opening adjustment members

17 and 62 may move in a linear motion between the disengagement position and the engagement position.
