Description

[Technical field]

[0001] The present invention relates to a control device for a vehicle door. [Background technology]

[0002] Patent Document 1 discloses a vehicle door opening and closing device. This opening and closing device is provided on a door for getting in and out of the vehicle and includes a door opening restriction means capable of restricting a maximum opening and closing angle of the door, and a door entry and exit action detection means capable of detecting an entry and exit action of an occupant.

[0003] The opening and closing device also includes a door opening and closing sensor capable of detecting the open / closed state of the door, an inner door handle sensor capable of detecting that the inner door handle has been operated, and an outer door handle sensor capable of detecting that the outer door handle has been operated.

[0004] The getting-in / out action detection means judges whether or not an occupant is getting out of the vehicle based on signals from the door opening / closing sensor and the inner door handle sensor, and also judges whether or not an occupant is getting in the vehicle based on signals from the door opening / closing sensor and the outer door handle sensor.

[0005] When the boarding / alighting operation detection means determines that a vehicle is being alighted, the door opening restriction means restricts the maximum opening / closing angle of the door to a first angle smaller than the full opening angle of the door, and when the boarding / alighting operation detection means determines that a vehicle is being alighted, the door opening restriction means restricts the maximum opening / closing angle of the door to a second angle larger than the first angle.

[0006] According to this opening and closing device, collision between the door and an obstacle is suppressed during disembarking, which is likely to cause the door to collide with an obstacle, while the convenience of the vehicle is maintained while suppressing collision between the door and an obstacle during getting on, which is relatively easy for the occupant to grasp the situation around the vehicle.

[0007] [Patent Document 1] JP 2008-121196 A Summary of the Invention [Problem to be solved by the invention]

[0008] However, in such a device, even if the door does not collide with an obstacle, if the boarding / alighting action detection means determines that the passenger is getting off the vehicle, the maximum opening / closing angle of the door is limited. This causes a problem of reduced convenience when getting off the vehicle. There is also room for improvement in that there is still a risk of the door colliding with an obstacle when the passenger gets on the vehicle. Furthermore, there is also a problem that the above-mentioned boarding / alighting action detection means requires a signal from a sensor to detect the boarding / alighting action, which complicates the structure of the device by the amount of the sensor. [Means for solving the problem]

[0009] A control device for a vehicle door to achieve the above-mentioned object includes a door main body portion connected to an edge of an opening of a vehicle via a door hinge to open and close the opening, a rotating member rotatably supported at a tip portion of the door main body portion, and a locking mechanism connected to the rotating member via a connecting member and restricting the opening and closing of the door main body portion, wherein the rotating member is rotatable between a first position where it is stored in the tip portion when the door main body portion is in a closed state, a second position where it protrudes outward from the tip portion when the door main body portion is in an open state, and a third position where it is rotated further away from the second position relative to the first position, and the locking mechanism has an engaging portion that engages with the door hinge by the action of a tensile load of the connecting member generated as the rotating member is rotated from the second position to the third position when the door main body portion is in the open state, to restrict the rotation of the door hinge.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of a control device for a vehicle door will be described with reference to Figs. 1 to 13. Hereinafter, the longitudinal direction of the vehicle 90 will be simply referred to as the longitudinal direction X, the width direction of the vehicle 90 will be simply referred to as the width direction Y, and the height direction of the vehicle 90 will be simply referred to as the height direction Z. In addition, the side approaching the interior of the vehicle in the width direction Y will be simply referred to as the inner side of the vehicle, and the side approaching the exterior side of the vehicle will be simply referred to as the outer side of the vehicle. In this embodiment, the present invention is embodied as a control device 97 for a front door 10 located on the right side when viewed from the rear to the front in the longitudinal direction X of the vehicle 90.

[0012] <Basic Configuration of the Control Device 97 of the Front Door 10> As shown in FIGS. 1 and 2, a vehicle 90 is provided with a front door 10 for opening and closing a door opening 92 formed on a side surface of a vehicle body 91 for passengers getting in and out of the vehicle, and a control device 97 for the front door 10.

[0013] The front door 10 is a so-called hinged door, and is connected to an edge 92a of a door opening 92 via a door hinge 20. More specifically, the front door 10 is connected to a front pillar 93 of a vehicle body 91 that constitutes a part of the edge 92a. This allows the front door 10 to rotate horizontally between a closed state in which the door opening 92 is closed (see FIGS. 1 and 5) and an open state in which the door opening 92 is open (see FIGS. 6 and 7).

[0014] The front door 10 has a door body portion 10a to which the door hinge 20 is attached, and a window frame portion 10b which, together with the door body portion 10a, forms a window opening 94. In the following description, the closed and open states of the front door 10 will be referred to as the closed and open states of the door body portion 10a.

[0015] The door main body 10a is provided with a locking mechanism 30, a rotating member 40, and a connecting member 50 that connects the locking mechanism 30 and the rotating member 40. In this embodiment, the door main body 10a, the door hinge 20, the locking mechanism 30, the rotating member 40, and the connecting member 50 configure a control device 97 for the front door 10.

[0016] Each component will be described in detail below. Hereinafter, each component will be described mainly when the door body 10a is in the closed state. For ease of explanation, in Fig. 2, some components are shown by two-dot chain lines when the door body 10a is in the open state.

[0017] <Door main body portion 10a> 1 and 2, the door main body 10a has a door inner panel 11 and a door outer panel 14 located on the vehicle outer side of the door inner panel 11. The door inner panel 11 and the door outer panel 14 are formed of, for example, a metal material.

[0018] The door inner panel 11 has a panel body portion 12 to which a door trim 95 is attached from the inside of the vehicle, and a flange portion 13 rising up from the outer edge of the panel body portion 12. The flange portion 13 extends from the outer edge of the panel main body portion 12 toward the door outer panel 14, and its tip is bent and extends away from the panel main body portion 12 in the front-rear direction X. A part of the flange portion 13 (hereinafter, flange portion 13a) faces a front pillar 93 of the vehicle body 91 in the front-rear direction X. In addition, a part on the opposite side to the flange portion 13a in the front-rear direction X (hereinafter, flange portion 13b) faces a center pillar 96 of the vehicle body 91.

[0019] The flange portion 13b is located at the rearmost part of the door main body portion 10a in the front-rear direction X. That is, the flange portion 13b is located at the most leading end side of the door main body portion 10a when viewed from the door hinge 20 side. That is, the flange portion 13b corresponds to the leading end according to the present invention.

[0020] As shown in FIG. 2, the flange portion 13b is provided with a storage portion 16 having a recessed shape in which the rotating member 40 is stored. 1 and 2, the door outer panel 14 covers the entire door inner panel 11 from the vehicle exterior side. This forms a space S1 surrounded by the panel body 12, the flange portion 13, and the door outer panel 14. The space S1 accommodates, for example, a regulator, a motor, and window glass related to a well-known power window device, as well as a door lock device and the like (all not shown).

[0021] <Door Hinge 20> As shown in FIGS. 2 and 3, the door hinge 20 has a vehicle body side fixed portion 21 fixed to the vehicle body 91, a door side fixed portion 25 fixed to the front door 10, and a hinge shaft 28 extending in the height direction Z.

[0022] The vehicle body side fixing portion 21 has a plate-shaped base portion 22 having fastening holes 22 a for fastening to the vehicle body 91 , and a pair of shaft support portions 23 , 24 protruding from the base portion 22 . The base portion 22 is fixed to a front pillar 93 of the vehicle body 91, for example, by screwing a nut onto a bolt inserted into the fastening hole 22a (both not shown).

[0023] 3, the pair of shaft supports 23, 24 protrude in a direction perpendicular to the surface 22c opposite the mounting surface 22b of the base 22. The pair of shaft supports 23, 24 are aligned in the height direction Z and extend parallel to each other. The pair of shaft supports 23, 24 are provided with a through hole (not shown) through which the hinge shaft 28 is inserted.

[0024] The tip surfaces 23a, 24a of the pair of shaft support portions 23, 24 are curved surfaces that are curved along a first circumferential direction C1 about the hinge shaft 28. A plurality of teeth 23b, 24b are provided on the tip surfaces 23a, 24a and aligned in the first circumferential direction C1.

[0025] As shown in Figures 2 and 3, the door side fixing portion 25 is a plate bent into an L shape, and has a base 26 having a fastening hole 26a for fastening to the front door 10, and an axis support portion 27 protruding from the base 26.

[0026] The base portion 26 is fixed to the flange portion 13a of the door inner panel 11, for example, by screwing a nut onto a bolt (both not shown) inserted into the fastening hole 26a. The shaft support portion 27 is bent from the base portion 26 and extends in a direction perpendicular to the base portion 26. The shaft support portion 27 is provided with a through hole (not shown) through which the hinge shaft 28 is inserted.

[0027] The door side fixing part 25 is composed of a pair of door side fixing parts 25a, 25b arranged in the height direction Z with the vehicle body side fixing part 21 in between. The pair of door side fixing parts 25a, 25b are arranged symmetrically above and below with the vehicle body side fixing part 21 in between.

[0028] Both ends of the hinge shaft 28 are crimped in a state where the hinge shaft 28 is inserted through the through holes (not shown) of the pair of shaft support parts 23, 24 and the through hole (not shown) of the shaft support part 27, so that the door side fixing part 25 is connected to the vehicle body side fixing part 21 so as to be rotatable in the first circumferential direction C1. The hinge shaft 28 corresponds to the rotation shaft of the door hinge according to the present invention.

[0029] <Lock mechanism 30> As shown in FIGS. 2 and 3, the lock mechanism 30 has an attachment portion 31, a lever , an engagement portion 35, and a biasing member .

[0030] The mounting portion 31 has a plate-shaped base portion 32 having fastening holes 32 a for fastening to the front door 10 , and a support shaft 33 protruding from the base portion 32 . The base 32 is fixed to the panel main body 12 of the door inner panel 11, for example, by screwing a nut (both not shown) onto a bolt inserted into the fastening hole 32a. The base 32 is fixed to the surface 12a of the panel main body 12 on the vehicle exterior side that constitutes the space S1.

[0031] The support shaft 33 protrudes in a direction perpendicular to the surface 32c of the base 32, the surface 32c being opposite the mounting surface 32b. Here, the direction perpendicular to the surface 32c is a direction perpendicular to an axis parallel to the hinge shaft 28.

[0032] As shown in FIGS. 2 and 3, a lever 34 is connected to the tip of the support shaft 33 so as to be rotatable about the support shaft 33 in the second circumferential direction C2. The lever 34 is in the shape of a long plate. One end 34a in the extension direction of the lever 34 is provided with a through hole 34c penetrating the lever 34 in the plate thickness direction. The other end 34b in the extension direction of the lever 34 is provided with a through hole 34d penetrating the lever 34 in the plate thickness direction.

[0033] As shown in FIG. 3, in the extending direction of the lever 34, a distance D1 from the support shaft 33 to the through hole 34d is set to be smaller than a distance D2 from the support shaft 33 to the through hole 34c.

[0034] The lever 34 is biased by a biasing member 38, such as a coil spring, attached to the support shaft 33 so that one end 34a moves toward the door hinge 20 and the other end 34b moves away from the door hinge 20 in the second circumferential direction C2.

[0035] As shown in FIGS. 2 and 3, the engagement portion 35 has an elongated arm portion 36 and a flat head portion 37. As shown in FIG. 3, one end 36a of the arm portion 36 in the extending direction is provided with a through hole 36b penetrating the arm portion 36.

[0036] A pin (not shown) serving as an axis is inserted through the through hole 36b of the arm portion 36 and the through hole 34d of the lever 34, and both ends of the pin are crimped, so that the arm portion 36 is rotatably connected to the other end 34b of the lever 34 in the second circumferential direction C2.

[0037] 2, the arm portion 36 is inserted into a through hole 15 that penetrates the flange portion 13a of the door inner panel 11 in the plate thickness direction. In this embodiment, the plate thickness direction of the flange portion 13a coincides with the radial direction R of the hinge shaft 28, and coincides with the front-rear direction X when the door main body portion 10a is in the closed state. The shape of the through hole 15 is configured to allow the arm portion 36 to slide relative to the through hole 15 in the plate thickness direction, while restricting movement in a direction intersecting the plate thickness direction.

[0038] As shown in FIG. 3, the head portion 37 is attached to the side opposite to the one end 36a in the extending direction of the arm portion 36. 2 and 3, the head portion 37 is sandwiched between the door-side fixing portions 25a and 25b in the height direction Z. This restricts the movement of the head portion 37 in the height direction Z.

[0039] The engagement portion 35 is maintained in a position extending linearly from the other end 34b of the lever 34 toward the hinge shaft 28 in the radial direction R of the hinge shaft 28 (the front-rear direction X in FIG. 2) by the through hole 15 and the door side fixing portions 25a, 25b.

[0040] As shown in FIG. 3, the head portion 37 has an opposing surface 37a that faces the shaft support portions 23, 24 of the vehicle body side fixing portion 21 in the fore-and-aft direction X with a gap S2 therebetween, and is provided with a plurality of teeth 37b that mesh with the plurality of teeth 23b, 24b of the vehicle body side fixing portion 21.

[0041] 3, 10, and 12, the locking mechanism 30 is configured such that the engaging portion 35 slides in the radial direction R when the lever 34 is rotated in the second circumferential direction C2 such that the other end 34b approaches the door hinge 20. More specifically, as shown in Figures 3, 11, and 13, the locking mechanism 30 is configured such that the head portion 37 of the engaging portion 35 slides in the radial direction R between the door side fixing portions 25a, 25b toward the vehicle body side fixing portion 21.

[0042] As shown in Fig. 3 and Figs. 10 to 13, in the lock mechanism 30, the sliding movement of the engaging portion 35 causes a plurality of teeth 37b provided on a head portion 37 of the engaging portion 35 to mesh with a plurality of teeth 23b, 24b of the vehicle body side fixed portion 21. As a result, the lock mechanism 30 is configured to restrict the rotation of the door hinge 20. More specifically, the lock mechanism 30 is configured to restrict the rotation of the door side fixed portion 25 relative to the vehicle body side fixed portion 21. That is, in this embodiment, the vehicle body side fixed portion 21 of the door hinge 20, the attachment portion 31, the lever 34, the engaging portion 35, and the biasing member 38 constitute the lock mechanism according to the present invention.

[0043] The interval S2 is set so that the head portion 37 does not come into contact with the vehicle body side fixed portion 21 when the lever 34 rotates from the position shown in Fig. 4 to the position shown in Fig. 10 and Fig. 11. On the other hand, the interval S2 is set so that the head portion 37 comes into contact with the vehicle body side fixed portion 21 when the lever 34 rotates to the position shown in Fig. 12 and Fig. 13.

[0044] <Rotating member 40> As shown in FIG. 4, the rotating member 40 has a plate-shaped main body portion 41 and a support shaft 42 extending in the height direction Z.

[0045] The main body 41 is made of a resin material that is softer than the door main body 10a. The main body 41 has a rectangular shape in a plan view, and has a pair of long sides 41a, 41b and a pair of short sides 41c, 41d.

[0046] Of the short sides 41c, 41d, the portion on the long side 41a side is supported within the storage portion 16 of the flange portion 13b via a support shaft 42. The main body portion 41 is connected to be rotatable about the support shaft 42 in the first circumferential direction C1.

[0047] 4 and 8, the main body 41 is biased by a biasing member (not shown) such as a coil spring so as to rotate in the first circumferential direction C1 from a position stored in the storage section 16 (hereinafter, the first position) to a position rotated toward the vehicle interior (hereinafter, the second position). In this embodiment, the second position is a position where the main body 41 is rotated 90 degrees from the first position in the first circumferential direction C1.

[0048] 9, the biasing member and the storage section 16 are configured to allow the main body 41 to rotate in the first circumferential direction C1 from the second position to a position rotated further toward the vehicle interior (hereinafter, referred to as the third position). In this embodiment, the third position is a position where the main body 41 is rotated further from the first position by more than 90 degrees in the first circumferential direction C1.

[0049] 2, when the main body 41 is in the second position, the long side 41b protrudes outward beyond the flange 13b of the door main body 10a. In other words, the long side 41b of the main body 41 protrudes further toward the tip side than the flange 13b, which is the tip of the door main body 10a when viewed from the door hinge 20 side.

[0050] 1, the main body 41 is held in the first position when the door main body 10a is closed by being sandwiched between the center pillar 96 and the flange portion 13b in the front-rear direction X. In other words, when the door main body 10a is closed, the main body 41 is restricted by the center pillar 96 from rotating from the first position to the second position.

[0051] As shown in FIGS. 1 and 2, a connection member 50 is attached to a second surface 41B of the main body 41 opposite to a first surface 41A facing the center pillar 96. <Connection member 50> As shown in FIG. 2, the connection member 50 is, for example, a metal wire, and is routed within the space S1 of the door main body 10a.

[0052] 2 and 3, one end 51 of the connection member 50 is connected to one end 34a of the lever 34 via a connecting member 53. A pin (not shown) as an axis is inserted through a through hole (not shown) formed in the connecting member 53 and a through hole 34c in the one end 34a, and both ends of the pin are crimped, so that the connecting member 53 is connected to the one end 34a of the lever 34 so as to be rotatable in the second circumferential direction C2.

[0053] As shown in FIG. 2, the other end 52 of the connection member 50 passes through the storage portion 16 and is coupled to the second surface 41B of the main body portion 41 of the rotating member 40. The length of the connecting member 50 is set to such an extent that when the rotating member 40 is rotated from the first position to the second position and the other end 52 is pulled rearward in the front-rear direction X, the one end 51 is pulled rearward in the front-rear direction X by the action of a tensile load. That is, the locking mechanism 30 is configured such that when the rotating member 40 is rotated from the first position to the second position, the action of the tensile load of the connecting member 50 causes the lever 34 connected to the one end 51 to rotate to a side where the one end 34a moves away from the door hinge 20. Also, when the rotating member 40 is rotated from the second position to the third position, the action of the tensile load of the connecting member 50 causes the lever 34 connected to the one end 51 to rotate to a side where the one end 34a moves further away from the door hinge 20.

[0054] Next, the operation of this embodiment will be described. 5 and 6, an occupant operates the front door 10 to change the door main body 10a from a closed state to an open state, whereby the main body 41 of the rotating member 40 rotates from a first position (see FIG. 4) to a second position (see FIG. 8).

[0055] 3 and 10, the lever 34 rotates in the second circumferential direction C2 with one end 34a moving away from the door hinge 20, i.e., the other end 34b moving closer to the door hinge 20. As a result, the engaging portion 35 slides between the door side fixing portions 25a and 25b in the radial direction R so as to move closer to the vehicle body side fixing portion 21 of the door hinge 20. At this time, the head portion 37 of the engaging portion 35 and the shaft support portions 23 and 24 of the vehicle body side fixing portion 21 face each other with a gap S2 therebetween. That is, the head portion 37 and the vehicle body side fixing portion 21 are not in contact with each other. Therefore, the rotation of the door hinge 20 is not restricted.

[0056] 2, the main body 41 in the second position protrudes further toward the tip side than the flange 13b of the door main body 10a when viewed from the door hinge 20. Therefore, when the door main body 10a is further rotated from the position in Fig. 6 to the position in Fig. 7, if an obstacle O is present on the path L along which the door main body 10a rotates from the closed position to the fully open position, the rotating member 40 is more likely to collide with the obstacle O than the door main body 10a.

[0057] As shown in FIG. 7, when the rotating member 40 collides with an obstacle O, the main body 41 is rotated from the second position (see FIG. 8) to the third position (see FIG. 9). 10 and 12, a tensile load is applied via the connecting member 50, causing the lever 34 to further rotate in the second circumferential direction C2 toward the other end 34b of the door hinge 20. As a result, the engaging portion 35 further slides between the door side fixing portions 25a, 25b in the radial direction R so as to approach the vehicle body side fixing portion 21 of the door hinge 20. Then, the multiple teeth 37b provided on the head portion 37 come into mesh with the multiple teeth 23b, 24b of the vehicle body side fixing portion 21 (see FIG. 13).

[0058] Therefore, the rotation of the door side fixing part 25 relative to the vehicle body side fixing part 21 is restricted. Next, the effects of this embodiment will be described. (1) The locking mechanism 30 has an engagement portion 35 that engages with the door hinge 20 to limit the rotation of the door hinge 20 due to the action of a tensile load of the connecting member 50 that occurs when the pivoting member 40 is pivoted from the second position to the third position when the door main body portion 10a is in the open state.

[0059] According to this configuration, the above-mentioned effects are achieved. On the other hand, unless the rotating member 40 hits the obstacle O, the above-mentioned effects do not limit the opening and closing of the door main body 10a. Therefore, it is possible to prevent the door main body 10a from colliding with the obstacle O with a simple structure while maintaining convenience.

[0060] (2) The lock mechanism 30 includes a lever 34 that rotates about a support shaft 33. The lever 34 is biased by a biasing member 38 in the second circumferential direction C2 so that one end 34a approaches the door hinge 20 and the other end 34b moves away from the door hinge 20.

[0061] According to this configuration, the lever 34 is biased such that the other end 34b of the lever 34 moves away from the door hinge 20. Therefore, when the rotating member 40 is in the first position or the second position, the engaging portion 35 is maintained in a state separated from the vehicle body side fixed portion 21 of the door hinge 20 by the distance S2.

[0062] On the other hand, when the rotating member 40 collides with the obstacle O and is rotated from the second position to the third position, a tensile load is applied to one end 34a of the lever 34 via the connecting member 50. This causes the lever 34 to rotate in the second circumferential direction C2 toward the side where the other end 34b approaches the door hinge 20. As a result, the multiple teeth 37b of the engaging portion 35 connected to the other end 34b approach the door hinge 20 and mesh with the multiple teeth 23b, 24b of the shaft supports 23, 24. Therefore, the locking mechanism 30 can be easily embodied by the lever 34 and the engaging portion 35.

[0063] (3) A plurality of teeth 23b, 24b are formed as uneven surfaces on the shaft support portions 23, 24 of the door hinge 20. A plurality of teeth 37b are formed as uneven surfaces on the head portion 37 of the engagement portion 35, which mesh with the plurality of teeth 23b, 24b to limit the rotation of the door hinge 20.

[0064] According to this configuration, the rotation of the door hinge 20 is restricted by meshing between the multiple teeth 23b, 24b formed on the door hinge 20 and the multiple teeth 37b formed on the engagement portion 35. Therefore, the lock mechanism 30 can be realized by a simple configuration in which the multiple teeth 23b, 24b are provided on the door hinge 20 and the multiple teeth 37b are provided on the engagement portion 35.

[0065] (4) The body 41 of the rotating member 40 is made of a resin material that is softer than the door inner panel 11 and the door outer panel 14 of the door body 10a. According to this configuration, even if the main body 41 of the rotating member 40 collides with the obstacle O, the obstacle O is less likely to be damaged by the main body 41 of the rotating member 40.

[0066] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.

[0067] The main body 41 of the rotating member 40 does not have to be made of a resin material softer than the door main body 10a. For example, the main body 41 of the rotating member 40 can be made of a metal material.

[0068] The shape of the main body 41 of the rotating member 40 is not limited to the rectangular shape in plan view exemplified in this embodiment. The main body 41 may have any shape, such as a rectangular shape or an elliptical shape, as long as it is located further toward the tip side than the flange portion 13b when viewed from the door hinge 20 side.

[0069] The second position does not have to be a position where the main body 41 of the rotating member 40 is rotated 90 degrees from the first position in the first circumferential direction C1. The angle by which the main body 41 rotates from the first position to the second position may be smaller or larger than 90 degrees, provided that the main body 41 is positioned further toward the tip side than the flange portion 13b of the door main body 10a when viewed from the door hinge 20 side.

[0070] The lock mechanism 30 is not limited to one in which the restriction of the rotation of the door hinge 20 is realized by the multiple teeth 23b, 24b of the vehicle body side fixed part and the multiple teeth 37b of the engagement part 35. The shape of the head part 37 of the engagement part 35 and the shapes of the shaft support parts 23, 24 of the vehicle body side fixed part 21 may be appropriately changed as long as they restrict the rotation of the door hinge 20. For example, the multiple teeth 23b, 24b, 37b may be omitted, and the rotation of the door hinge 20 may be restricted by the action of friction between the head part 37 of the engagement part 35 and the shaft support parts 23, 24 of the vehicle body side fixed part 21.

[0071] The vehicle body side fixing portion 21 of the door hinge 20 is not limited to having the two shaft support portions 23, 24. The vehicle body side fixing portion 21 may have only one shaft support portion that engages with the engagement portion 35.

[0072] The vehicle door control device according to the present invention is not limited to the control device 97 of the front door 10 located on the right side when looking forward from the rear in the longitudinal direction X of the vehicle 90. The present invention may be applied to any hinged door that is connected to the vehicle body 91 via a door hinge 20. Examples of the hinged door include a rear door on the rear seat side and a back door.

[0073] <Additional Notes> Each of the above embodiments includes the configurations described in the following supplementary notes. [Appendix 1] A control device for a vehicle door, comprising: a door main body portion connected to an edge portion of an opening of a vehicle via a door hinge to open and close the opening; a rotating member rotatably supported at a tip portion of the door main body portion; and a locking mechanism connected to the rotating member via a connecting member and restricting opening and closing of the door main body portion, wherein the rotating member is rotatable between a first position where it is stored in the tip portion when the door main body portion is in a closed state, a second position where it protrudes outward from the tip portion when the door main body portion is in an open state, and a third position where it is rotated further away from the second position with respect to the first position, and the locking mechanism has an engaging portion that engages with the door hinge by the action of a tensile load of the connecting member generated as the rotating member is rotated from the second position to the third position when the door main body portion is in the open state, to restrict the rotation of the door hinge.

[0074] [Appendix 2] The locking mechanism includes a lever that rotates around an axis perpendicular to an axis parallel to the rotation axis of the door hinge, the connecting member is connected to one end of the lever, and the engagement portion is connected to the other end of the lever, and the lever is biased so that, in the rotation direction of the lever, the one end approaches the door hinge and the other end moves away from the door hinge. The vehicle door control device described in [Appendix 1].

[0075] [Appendix 3] The locking mechanism includes the door hinge, and the door hinge and the engagement portion are formed with uneven shapes that limit the rotation of the door hinge by fitting into each other. A control device for a vehicle door described in [Appendix 1] or [Appendix 2].
