Description

TECHNICAL FIELD

[0001] The present application relates to a door device for a vehicle. BACKGROUND

[0002] In the past, there has been a door device for a vehicle that includes a first link arm and a second link arm having a first turning joint with respect to a vehicle body and a second turning joint with respect to a door of the vehicle. Such a door device for a vehicle causes a door provided at a door opening portion thereof to perform opening and closing actions based on the operation of a link mechanism formed by the first link arm and the second link arm. In addition, for example, the door device for a vehicle described in Patent Document 1 includes a clamping arm that turns integrally with the link arm with respect to the first turning joint with respect to the vehicle body. Further, the clamping arm is caused to move to a fully open position by the door of the vehicle due to the turning of the link arm, and thereby a fitting portion having a spherical shape is fitted with a clamping groove holding portion provided at the vehicle body. Further, this becomes a structure in which the door of the vehicle is held at the fully open position based on the force of an elastic member that presses the fitting portion against the clamping groove holding portion.

[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] However, in the structure of the above-described prior art, a space is required for the clamping arm to turn in conjunction with the link arm. Further, there is a problem in that this becomes a restriction when mounted on a vehicle. SUMMARY OF THE INVENTION

[0008] MEANS OF SOLVING THE PROBLEMS

[0009] A vehicle door device that solves the above-described technical problem includes: first and second link arms having a first rotational link point with respect to a vehicle body and a second rotational link point with respect to a door of the vehicle; a tiltable lever provided at an opening-side end portion of a door opening portion that is opened and closed by the door based on operation of a link mechanism formed by the first and second link arms; a biasing member that biases the tiltable lever to maintain the tiltable lever in a standing state; and a clamping mechanism that engages with the tiltable lever in the standing state by movement of the door to a fully open position, thereby maintaining the door at the fully open position, the first link arm is provided at a position that approaches the opening-side end portion of the door opening portion by opening operation of the door, the clamping mechanism is provided at the first link arm, and the tiltable lever is tilted by being pressed by the door moved to the fully closed position, thereby being accommodated in a gap between the door and the opening-side end portion of the door opening portion.

[0010] According to the above-described structure, the door can be stably maintained at the fully open position based on the engagement force of the tiltable lever and the clamping mechanism. Also, in a case where the door is at the fully closed position, the tiltable lever can be accommodated in the gap between the door and the opening-side end portion of the door opening portion by tilting of the tiltable lever, even if the gap is narrow. Also, as a result, excellent mountability can be ensured.

[0011] In the vehicle door device that solves the above-described technical problem, it is preferable that the clamping mechanism include: a pair of engagement members disposed at positions facing each other; and a biasing member that biases the pair of engagement members in a direction in which the engagement members approach each other, the clamping mechanism engaging with the tiltable lever in a state in which the tiltable lever is inserted between the pair of engagement members.

[0012] According to the above-described structure, the clamping mechanism that engages with the tiltable lever based on rotation of the first link arm that moves the door to the fully open position can be formed. Also, as a result, the door can be stably maintained at the fully open position with a simple structure.

[0013] In the vehicle door device that solves the above-described technical problem, it is preferable that a gap between the door and the opening-side end portion of the door opening portion be provided with an outer seal member and an inner seal member separated in a vehicle width direction, and the tiltable lever be accommodated at a position between the outer seal member and the inner seal member.

[0014] According to the above-described structure, the tiltable lever can be accommodated in a space having high waterproofness formed between the outer seal member and the inner seal member. Also, as a result, high reliability can be ensured.

[0015] In the vehicle door device that solves the above-described technical problem, it is preferable that the clamping mechanism has an abutting portion that abuts against a support member of the tiltable lever provided at the open side end portion of the door opening portion, and a buffer member is provided at at least one of the abutting portion or the support member of the tiltable lever.

[0016] According to the above-described structure, the clamping mechanism and the support member of the tiltable lever function as a stopper portion that restricts the first link arm from turning toward the opening operation direction beyond the fully open position of the door. Also, by interposing the buffer member between these clamping mechanism and the support member of the tiltable lever, it is possible to suppress vibration and sound due to abutment of the two, and it is possible to ensure a high quality feel.

[0050] Hereinafter, an embodiment of a vehicle door device will be described with reference to the drawings.

[0051] As shown in Figs. Figure 1 and Figure 2 , the vehicle 1 of the present embodiment is provided with a door opening portion 3 provided on the side surface of a vehicle body 2. Further, a first link arm 11 and a second link arm 12 that support a door 5 of the vehicle 1 to the door opening portion 3 are provided in the door opening portion 3.

[0052] In detail, in the vehicle 1 of this embodiment, the first connecting arm 11 and the second connecting arm 12 each have a first rotatable connection point X1 relative to the vehicle body 2 and a second rotatable connection point X2 relative to the door 5. Specifically, the first connecting arm 11 is connected to the vehicle body 2 by means of a support shaft N1a extending in the vertical direction (in each figure), and is connected to the door 5 by means of a support shaft N1b extending in the vertical direction. Similarly, the second connecting arm 12 is also connected to the vehicle body 2 by means of a support shaft N2a extending in the vertical direction, and is connected to the door 5 by means of a support shaft N2b extending in the vertical direction.

[0053] That is, such as Figures 3-5 As shown, in the vehicle 1 of this embodiment, the first connecting arms 11 and the second connecting arms 12 form a linkage mechanism 15 having a structure as a four-section linkage. Furthermore, the vehicle 1 of this embodiment is configured such that the door 5 supported on the door opening portion 3 is opened and closed based on the operation of the linkage mechanism 15.

[0054] More specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, vehicle 1 uses the first connecting arm 11 and the second connecting arm 12 to support the door 5 on the rear side of the vehicle. Figure 1 Middle, left side Figure 2 The door opening 3 (on the right side) is shown in the figure. In the vehicle 1 of this embodiment, the first connecting arms 11 and the second connecting arms 12 each have a first rotating connection point X1 in the rear edge 3r of the door opening 3, which is rotatably connected to the vehicle body 2. In addition, in the vehicle 1 of this embodiment, the first connecting arm 11 is positioned above the second connecting arm 12. Moreover, the first connecting arm 11 has a second rotating connection point X2 in the door 5 at approximately the center position in the front-rear direction, which is rotatably connected to the door 5, and the second connecting arm 12 has a second rotating connection point X2 in the door 5 near the front end 5f of the door 5. Thus, in the vehicle 1 of this embodiment, a vehicle door device 20 is formed in which the door 5 is opened and closed based on the operation of the linkage mechanism 15 formed by the first connecting arms 11 and the second connecting arms 12.

[0055] Specifically, such as Figures 3-5As shown, the vehicle door device 20 of the present embodiment rotates the first link arms 11 and the second link arms 12 about the first turning joint X1 in the counterclockwise direction in the respective drawings, thereby causing the door 5 of the vehicle 1 supported by the first link arms 11 and the second link arms 12 to perform an opening operation toward the rear side of the vehicle (left side in the respective drawings). Also, the door 5 is configured to perform a closing operation toward the front side of the vehicle (right side in the respective drawings) by rotating the first link arms 11 and the second link arms 12 about the first turning joint X1 in the clockwise direction in the respective drawings.

[0056] In addition, in the vehicle door device 20 of the present embodiment, the opening and closing operation trajectory of the door 5 is defined based on the operation of the link mechanism 15 formed by the first link arms 11 and the second link arms 12. That is, as shown, the movement component in the vehicle front-rear direction becomes large at the intermediate position where the first link arms 11 and the second link arms 12 are in a state of extending in the vehicle width direction (vertical direction). Figure 4 Figures 3-5 In addition, as shown, the movement component in the vehicle width direction becomes large as the opening and closing operation position of the door 5 approaches the fully closed position P0, and the first link arms 11 and the second link arms 12 are in a state of extending in the vehicle front-rear direction (left-right direction), thereby causing the movement component in the vertical direction to become large. Figure 3 Figures 3-5

[0057] In addition, as shown, in the vehicle door device 20 of the present embodiment, the first link arms 11 have the second turning joint X2 linked to the door 5 at a position closer to the center of gravity G than the second link arms 12. Also, in terms of the support function of supporting the load of the door 5, the vehicle door device 20 of the present embodiment is configured such that the first link arms 11 become the main link 21 that supports a larger door load, and the second link arms 12 become the sub link 22 that supports a smaller door load. Figures 1-5 In addition, in the vehicle door device 20 of the present embodiment, the first link arms 11 have a larger diameter than the second link arms 12. Also, the vehicle door device 20 is thereby configured to impart a higher support rigidity to the first link arms 11 positioned at the main link 21.

[0058]

[0059] In addition, as shown, in the vehicle door device 20 of the present embodiment, the first link arms 11 have a larger diameter than the second link arms 12. Also, the vehicle door device 20 is thereby configured to impart a higher support rigidity to the first link arms 11 positioned at the main link 21. Figure 6 Figure 7 ​​​​​As shown, the vehicle door device 20 of the present embodiment is provided with the drive arm 23 that is rotatably connected to the first link arm 11 positioned at the first link 21 at a position between the first rotation joint X1 and the second rotation joint X2. Also, the vehicle door device 20 is provided with the actuator 25 that rotates the drive arm 23 by applying a driving force thereto, thereby driving the link mechanism 15. Also, the vehicle door device 20 of the present embodiment thereby has a structure as a power door device 30 that causes the door 5 to perform opening and closing actions based on the driving force of the actuator 25.

[0060] Specifically, in the vehicle door device 20 of the present embodiment, the joint position of the drive arm 23 with respect to the first link arm 11, i.e., the third rotation joint X3 in the first link arm 11, is set at a position closer to the first rotation joint X1 than the second rotation joint X2 (see FIG. 2). Figures 3-5 In addition, the actuator 25 of the present embodiment is fixed to the vehicle body 2 at a position below the first link arm 11. Also, in the vehicle 1 of the present embodiment, the actuator 25 is disposed at a position where the output shaft 25x thereof becomes substantially coaxial with the first rotation joint X1. Also, the vehicle door device 20 of the present embodiment has a structure in which one end side of the drive arm 23 disposed in line with the first link arm 11 is jointed to the output shaft 25x of the actuator 25.

[0061] That is, in the vehicle door device 20 of the present embodiment, the first link arm 11 and the second link arm 12 rotate in conjunction with the rotation of the drive arm 23 based on the driving force of the actuator 25. Also, the vehicle door device 20 of the present embodiment thereby has a structure in which the door 5 performs opening and closing actions based on the actions of the link mechanism 15 formed by these first link arm 11 and second link arm 12.

[0062] More specifically, the first end portion 23a of the drive arm 23 of the present embodiment is jointed to the output shaft 25x of the actuator 25 in a manner that does not rotate with respect to the output shaft 25x of the actuator 25. In addition, the drive arm 23 is provided with the engagement protrusion 33 that is provided at the second end portion 23b thereof and protrudes upward. Also, the first link arm 11 is provided with the engagement recess 34 that is provided at the lower surface 1 lb thereof. Also, in the vehicle door device 20 of the present embodiment, the engagement protrusion 33 of the drive arm 23 is engaged with the engagement recess 34 provided at the first link arm 11, thereby forming the third rotation joint X3.

[0063] Specifically, in the vehicle door device 20 of this embodiment, the engaging protrusion 33 on the drive arm 23 side is shaft-shaped, more specifically, it is a pin-shaped portion passing through the second end 23b of the drive arm 23. Furthermore, the engaging recess 34 on the first connecting arm 11 side is formed by mounting a bushing 37 with an elongated hole 37x to a mounting recess 36 provided on the lower surface 11b of the first connecting arm 11. Moreover, this bushing 37 is formed using a soft material such as resin, rubber, or an elastomer. Thus, the vehicle door device 20 of this embodiment has a structure that can suppress collision noise generated by the contact between the first connecting arm 11 and the drive arm 23, thereby ensuring high quietness.

[0064] (Maintenance structure for the door in the fully open position)

[0065] Next, the retaining structure of the door 5 in the fully open position P1 of the vehicle door device 20 actually installed in this embodiment will be described.

[0066] like Figure 5 and Figure 8 As shown, the vehicle door device 20 of this embodiment includes a reversible bar 40 provided at the rear edge 3r of the door opening 3. Specifically, in the vehicle 1 of this embodiment, a support member 42 is fixed to the rear edge 3r of the door opening 3, and the support member 42 has a vertically oriented ( Figure 8 A support shaft 41 extends in a direction orthogonal to the plane of the paper. Furthermore, the reversible rod 40 of this embodiment is axially supported on the support member 42 in a state where it can rotate around the support shaft 41.

[0067] Specifically, the reversible rod 40 in this embodiment is achieved by... Figure 8 Rotate counterclockwise in the middle, so that its top 40a faces outward in the vehicle width direction. Figure 8 The reversible lever 40 moves from the middle (upper side) to the upper side. Furthermore, the reversible lever 40 abuts against the stop portion 43 provided on the support member 42, thereby restricting the rotation of its top end 40a towards the outer side in the vehicle width direction. In addition, the reversible lever 40 of this embodiment has an engaging protrusion 44 on the base end side supported by the support shaft 41 that engages with the stop portion 43 on the support member 42 side. Furthermore, in the vehicle door device 20 of this embodiment, the reversible lever 40 moves from the rear edge 3r of the door opening 3 towards the front side of the vehicle (…). Figure 8 The protruding state (on the right side) is the upright state of the reversible lever 40.

[0068] Furthermore, the vehicle door device 20 of this embodiment includes a force-applying member 45, which applies force to the reversible bar 40 in the uprighting direction, that is, in Figure 8In the present embodiment, a force that rotates in the counterclockwise direction is applied. Specifically, the support member 42 of the present embodiment is provided with a torsion coil spring 46 that is fitted to the support shaft 41. Also, the vehicle door device 20 of the present embodiment is structured such that, by using this torsion coil spring 46 as the biasing member 45, the engagement protrusion 44 of the tiltable lever 40 is maintained in abutment with the stopper 43 on the support member 42 side, i.e., in the erected state, based on the elastic force thereof.

[0069] In addition, as shown in Figures 3-5 , Figure 9 and Figure 10 , in the vehicle 1 of the present embodiment, the rear edge portion 3r of the door opening portion 3 in which the tiltable lever 40 is provided is moved in the direction in which the door 5 is opened, based on the operation of the link mechanism 15 formed by the first link arm 11 and the second link arm 12. Also, the tiltable lever 40 of the present embodiment is disposed at a position that abuts against the door 5 that is moving toward the fully closed position P0 at the rear edge portion 3r that is the open side end portion 47 of the door opening portion 3.

[0070] Furthermore, as shown in Figure 9 and Figure 10 , the tiltable lever 40 of the present embodiment is rotated in the clockwise direction in each figure by being pressed by the door 5 that is moving toward the fully closed position P0, so that the tip end 40a thereof moves toward the inner side in the vehicle width direction (lower side in each figure). Also, the vehicle door device 20 is thereby structured such that the tiltable lever 40 becomes in a tilted state that is disposed in cooperation with the rear edge portion 3r of the door opening portion 3 that faces toward the front side of the vehicle (right side in each figure).

[0071] In addition, the vehicle door device 20 of the present embodiment is provided with a cover member 48 that is disposed at the rear end portion 5r of the door 5 that abuts against the tiltable lever 40. In the vehicle door device 20 of the present embodiment, this cover member 48 is constructed using a relatively soft material such as resin. Also, the vehicle door device 20 of the present embodiment is thereby structured to protect the door 5 and the tiltable lever 40.

[0072] In addition, in the vehicle 1 of the present embodiment, an outer side sealing member 51 is provided at the rear end portion 5r of the door 5, and is disposed in the gap 50 between the rear end portion 5r of the door 5 and the open side end portion 47 of the door opening portion 3, by the movement of the door 5 toward the fully closed position P0. Also, an inner side sealing member 52 is provided at the rear edge portion 3r of the door opening portion 3 that is the open side end portion 47, and is disposed on the inner side in the vehicle width direction (lower side in each figure) compared to the outer side sealing member 51. Figure 10The lower part of the door 5 is positioned in the gap 50 between the rear end 5r of the door 5 and the open end 47 of the door opening 3, which is also located when the door 5 moves to the fully closed position P0. Furthermore, in the vehicle door device 20 of this embodiment, the reversible rod 40 is provided between these outer sealing members 51 and inner sealing members 52.

[0073] Specifically, in this embodiment, the outer sealing member 51 and the inner sealing member 52 are formed using a soft, elastic material such as rubber or an elastomer. Furthermore, these outer sealing members 51 and inner sealing members 52 extend vertically in a manner that wraps around the rear end 5r of the door 5 and the opening end 47 of the door opening 3. That is, as the door 5 moves to the fully closed position P0, these outer sealing members 51 and inner sealing members 52 are respectively compressed and clamped between the rear end 5r of the door 5 and the opening end 47 of the door opening 3. Furthermore, for ease of explanation, in... Figure 10 The description of the contact portion on the door 5 side where the inner sealing member 52 is sandwiched between the opening end 47 of the door opening 3 is omitted. Furthermore, the reversible rod 40 of this embodiment is thus structured such that it is housed inside a space with high water resistance formed between the outer sealing member 51 and the inner sealing member 52.

[0074] In addition, such as Figure 5 As shown, the vehicle door device 20 of this embodiment includes a clamping mechanism 60, which engages with the reversible bar 40, which is held in the upright state as described above, by moving the door 5 to the fully open position P1.

[0075] In detail, such as Figures 3-5 As shown, in the vehicle door device 20 of this embodiment, the clamping mechanism 60 is integrated with the first connecting arm 11 positioned on the main connecting rod 21. Furthermore, in the vehicle 1 of this embodiment, as described above, the first connecting arm 11 is positioned near the rear edge 3r of the door opening 3, which becomes the open-side end 47 when the door 5 is opened. Moreover, the clamping mechanism 60 is fixed to the first connecting arm 11 at a position facing the reversible rod 40 provided at the open-side end 47 of the door opening 3 when rotated in the direction that the door 5 is opened. Furthermore, the vehicle door device 20 of this embodiment is structured such that the door 5 is held in the fully open position P1 based on the engaging force between the clamping mechanism 60 and the reversible rod 40.

[0076] Specifically, such as Figure 11 and Figure 12As shown, the clamping mechanism 60 of this embodiment includes a generally quadrangular box-shaped housing 62, which has an insertion hole 61 for inserting the tip 40a of the retractable rod 40. Furthermore, the clamping mechanism 60 has a pair of engaging members 63, 63 disposed within the housing 62 at opposite positions. Moreover, the clamping mechanism 60 includes force-applying members 64, 64 that apply force to the pair of engaging members 63, 63 in a direction that brings them closer together. In this embodiment, the force-applying members 64, 64 are, for example, compression coil springs. The clamping mechanism 60 of this embodiment is structured such that the retractable rod 40 is engaged with the pair of engaging members 63, 63 when inserted from the tip 40a side.

[0077] That is, in the clamping mechanism 60 of this embodiment, by moving the door 5 to the fully open position P1, based on the rotation of the first connecting arm 11, the reversible rod 40 is inserted into the housing 62 through the insertion hole 61 facing the open end 47 of the door opening 3. Furthermore, each engaging member 63, 63 is positioned within the housing 62 in the direction of insertion of the reversible rod 40 (…). Figure 11 The force is applied in a direction approximately orthogonal to the direction from the top to the bottom (as shown in the figure, the left-right direction). Furthermore, the clamping mechanism 60 clamps the reversible rod 40 inserted into the housing 62 from both sides of its width direction via a pair of engaging members 63, 63 that are subjected to force by the force-applying members 64, 64. In other words, in the vehicle door device 20 of this embodiment, the reversible rod 40 inserted into the housing 62 is arranged between these pairs of engaging members 63, 63 in such a way that it presses against the force of the force-applying members 64, 64. Therefore, the clamping mechanism 60 of this embodiment is structured such that it can restrict the rotation of the first connecting arm 11 based on the engaging force of the reversible rod 40 clamped between the pair of engaging members 63, 63.

[0078] Furthermore, the clamping mechanism 60 of this embodiment has an annular buffer member 65 that is fixedly mounted to the decorative surface 62s of the housing 62 in a manner surrounding the insertion hole 61. In the clamping mechanism 60 of this embodiment, the buffer member 65 is formed using a soft material with elasticity, such as rubber or an elastomer. Additionally, the clamping mechanism 60 of this embodiment is located on the side opposite to the insertion hole 61 (…). Figure 11 The lower part of the housing 62 has an insertion hole 66. Furthermore, the first connecting arm 11 has a hollow portion (not shown) at the position where the clamping mechanism 60 is fixed. Thus, the vehicle door device 20 of this embodiment has the following structure: the top end 40a of the reversible rod 40, which passes through the housing 62 of the clamping mechanism 60 in a state of insertion through the insertion hole 66, is disposed within the first connecting arm 11.

[0079] In addition, such asFigures 3-5 As shown, in the vehicle door device 20 of the present embodiment, a force in the direction of the opening operation is applied to the door 5 by the driving force of the actuator 25 or the operation force of the user, and the first link arm 11 is rotated in the direction away from the open side end portion 47 of the door opening portion 3. As a result, it appears that the tiltable rod 40 inserted into the housing 62 through the insertion hole 61 is pulled out against the force of the force applying member 64, 64 that sandwiches the tiltable rod 40 between the pair of engagement members 63, 63. Also, the vehicle door device 20 of the present embodiment is configured such that the engagement of the clamping mechanism 60 and the tiltable rod 40 is released.

[0080] Next, the effects of the present embodiment will be described.

[0081] That is, the door 5 supported by the first link arm 11 is held at the fully closed position P0 by the engagement of the tiltable rod 40 provided at the open side end portion 47 of the door opening portion 3 and the clamping mechanism 60 provided at the first link arm 11. Also, the tiltable rod 40 is tilted by being pressed against the door 5 moving toward the fully closed position P0. Further, the tiltable rod 40 is housed in the gap 50 between the door 5 moved to the fully closed position P0 and the open side end portion 47 of the door opening portion 3 in this tilted state.

[0082] Next, the effects of the present embodiment will be described.

[0083] (1) The vehicle door device 20 is provided with the first link arm 11 and the second link arm 12 having the first rotation link point X1 with respect to the vehicle body 2 and the second rotation link point X2 with respect to the door 5 of the vehicle 1. In addition, the vehicle door device 20 is provided with the tiltable rod 40 provided at the open side end portion 47 of the door opening portion 3 opened and closed by the door 5 based on the operation of the link mechanism 15 formed by the first link arm 11 and the second link arm 12, and the force applying member 45 applying a force to the tiltable rod 40 to hold it in the upright state. Further, the vehicle door device 20 is provided with the clamping mechanism 60 engaging with the tiltable rod 40 in the upright state by the movement of the door 5 to the fully open position PI, thereby holding the door 5 at the fully open position PI. The first link arm 11 is provided at a position approaching the open side end portion 47 of the door opening portion 3 by the opening operation of the door 5, and the clamping mechanism 60 is provided integrally with the first link arm 11. Also, the tiltable rod 40 is tilted by being pressed by the door 5 moved to the fully closed position P0, and thereby housed in the gap 50 between the door 5 and the open side end portion 47 of the door opening portion 3.

[0084] According to the above structure, the door 5 can be stably held in the fully open position PI based on the engagement force of the tiltable lever 40 and the clamping mechanism 60. Also, in the case where the door 5 is in the fully closed position PO, the tiltable lever 40 can be housed in the gap 50 even if the gap 50 formed between the door 5 and the open side end portion 47 of the door opening portion 3 narrows by tilting the tiltable lever 40. Also, as a result, excellent mountability can be ensured.

[0085] For example, there are points such as less restrictions on the vehicle body 2 side, and the ability to ensure a large opening space of the door opening portion 3. Also, productivity and design freedom can be simultaneously achieved. Also, by integrating the clamping mechanism 60 and the first link arm 11, weight reduction and cost reduction can be achieved.

[0086] (2) The clamping mechanism 60 has a pair of engagement members 63, 63 disposed at positions facing each other, and a pair of force applying members 64, 64 that apply force to the pair of engagement members 63, 63 in a direction in which the members approach each other. Also, the tiltable lever 40 in the erected state is inserted between the pair of engagement members 63, 63, and the tiltable lever 40 is engaged.

[0087] According to the above structure, the clamping mechanism 60 that engages with the tiltable lever 40 based on the rotation of the first link arm 11 that moves the door 5 to the fully open position PI can be formed. Also, as a result, the door 5 can be stably held in the fully open position PI with a simple structure.

[0088] (3) The gap 50 between the door 5 moved to the fully closed position PO and the open side end portion 47 of the door opening portion 3 is provided with an outer side sealing member 51 and an inner side sealing member 52 that are separated in the vehicle width direction. Also, the tiltable lever 40 is housed in the gap 50 at a position between the outer side sealing member 51 and the inner side sealing member 52.

[0089] According to the above structure, the tiltable lever 40 can be housed in a space with high waterproofness formed between the outer side sealing member 51 and the inner side sealing member 52. Also, as a result, high reliability can be ensured.

[0090] (4) The vehicle door device 20 has a drive arm 23 that has a third rotation link point X3 at a position between a first rotation link point XI and a second rotation link point X2, and is linked with the first link arm 11. Also, the vehicle door device 20 has an actuator 25 that drives the link mechanism 15 by rotating the drive arm 23 by applying a driving force to the drive arm 23.

[0091] According to the above structure, the power door device 30 that causes the door 5 to perform opening and closing operations based on the driving force of the actuator 25 can be formed in a simple and compact structure. In addition, the degree of freedom of arrangement of the actuator 25 can be ensured.

[0092] Furthermore, the above-described embodiments can be modified as follows. The above-described embodiments and the following modifications can be combined with each other without creating technical inconsistencies.

[0093] In the above embodiment, the first connecting arm 11, which has a structure as a main connecting arm 21, is positioned above the second connecting arm 12, which has a structure as a secondary connecting arm 22. However, this is not a limitation; the second connecting arm 12 may also be positioned above the first connecting arm 11. Furthermore, it is also possible to use a structure in which the first connecting arm 11, located near the opening end 47 of the door opening 3, serves as the secondary connecting arm 22, and the second connecting arm 12, located further away from the opening end 47 of the door opening 3, serves as the main connecting arm 21.

[0094] In the above embodiment, the clamping mechanism 60 includes a pair of engaging members 63, 63 disposed at opposite positions to each other, and force-applying members 64, 64 applying force to the pair of engaging members 63, 63 in a direction that brings them closer to each other. Furthermore, the pair of engaging members 63, 63 and the force-applying members 64, 64 are housed in a generally quadrangular box-shaped housing 62 having an insertion hole 61 with a reversible rod 40.

[0095] However, it is not limited to this. As long as it can engage with the retractable lever 40 in the upright state to hold the door 5 in the fully open position P1, the structure of the clamping mechanism 60 can be arbitrarily changed. For example, the shape of the housing 62 can be arbitrarily changed. Alternatively, it can be a structure in which a pair of rollers that allow the retractable lever 40 to be inserted between the two while rotating around the support shaft can be used as a locking component. Furthermore, the force-applying components 64 are not limited to compression coil springs; other spring components such as leaf springs can be used, or a structure using elastic components other than springs can be used.

[0096] Regarding the reversible lever 40, its shape can be arbitrarily changed, for example, by having a large-diameter portion at the top 40a to increase the engaging force. Furthermore, the shape of the support member 42 can also be arbitrarily changed. Moreover, the force-applying member 45 of the reversible lever 40 is not limited to a torsion coil spring 46; it can use other spring components or a structure using elastic components other than springs.

[0097] like Figure 13 As shown, it can also be a structure in which the clamping mechanism 60B provided on the first connecting arm 11 abuts against the support member 42B of the reversible rod 40 provided on the opening side end 47 of the door opening portion 3, by moving the door 5 to the fully open position P1. Specifically, in this Figure 13In the example shown, the decorative surface 62s of the housing 62B, which has the insertion hole 61 of the reversible rod 40, becomes the abutment portion 71 on the clamping mechanism 60B side, which abuts against the support member 42B of the reversible rod 40. Furthermore, a cushioning member 75 formed of a soft, elastic material such as rubber or an elastomer is provided on the abutment portion 72 on the support member 42B side of the reversible rod 40.

[0098] By adopting the structure described above, the clamping mechanism 60B and the support member 42B of the reversible lever 40 function as a stop to limit the first connecting arm 11 from rotating in the opening direction beyond the fully open position P1 of the door 5. Furthermore, by intervening between these clamping mechanisms 60B and the support member 42B of the reversible lever 40, vibration and noise caused by their contact can be suppressed, ensuring a high-quality feel.

[0099] Alternatively, it could be a buffer component 65 fixedly installed on the decorative surface 62s of the housing 62 (see reference). Figure 11 The structure is such that the buffer member 42B of the reversible rod 40 abuts against the support member 42B of the reversible rod 40. Furthermore, the structure can also have buffer members provided on both the support member 42B side and the clamping mechanism 60B side. That is, a buffer member can be provided on at least one of the clamping mechanism 60B and the support member 42B of the reversible rod 40. Moreover, the shapes of the abutting portion 71 on the clamping mechanism 60B side and the abutting portion 72 on the support member 42B side of the reversible rod 40 can be arbitrarily changed.

[0100] In the above embodiment, the first connecting arm 11, which has a structure as a main connecting rod 21, is driven by the driving arm 23 and the actuator 25. However, it is not limited to this; the second connecting arm 12, which has a structure as a secondary connecting rod 22, can also be driven. Furthermore, it is also possible to drive both the first connecting arm 11 and the second connecting arm 12.

[0101] That is, the number and configuration of the drive arms 23 and actuators 25 can be arbitrarily changed. For example, the actuators 25 can be configured above the first connecting arm 11 or below the second connecting arm 12. Alternatively, the actuators 25 can be configured on the door 5 side. Furthermore, the actuators 25 can be configured on both the vehicle body 2 side and the door 5 side.

[0102] In the above embodiment, the structure is applied to the door 5 of vehicle 1 opening towards the rear of the vehicle, but it can also be applied to a structure where the door 5 opens towards the front of the vehicle. Furthermore, it can also be applied to a structure where the support shafts N1a, N1b and N2a, N2b of the first connecting arm 11 and the second connecting arm 12 are tilted. Moreover, it can also be applied to a manually operated door device that does not have a drive source such as the actuator 25.

[0103] Next, the technical ideas that can be grasped from the above-described embodiments and modifications are described.

[0104] (i) The door device for a vehicle includes: a driving arm having a third turning joint at a position between the first turning joint and the second turning joint with respect to at least either of the first link arm and the second link arm, and being linked with at least either of the first link arm and the second link arm; and an actuator that rotates the driving arm by applying a driving force to the driving arm, thereby driving the link mechanism.

[0105] According to the above-described structure, a power door device that causes a door to perform opening and closing actions based on a driving force of an actuator can be formed in a simple and compact structure. In addition, the degree of freedom of arrangement of the actuator can be ensured.
