Description

BACKGROUND OF THE INVENTION Area of ​​the invention

[0001] The invention relates to vehicle door devices. Explanation of the state of the art

[0002] A technique relating to vehicle door handles is known in the prior art (see, for example, the unexamined Japanese patent publications JP 2017-066 605 A and JP 2017-166 265 A). For instance, JP 2017-066605A discloses a technique relating to a vehicle exterior handle with an exterior handle whose outer surface is flush with the outer surface of an outer sheet metal panel when not in use. In this technique, when an occupant pushes the exterior handle into a motorized actuation position, a switch is pressed and the exterior handle pivots into a holding position (actuation position). The occupant then pulls the exterior handle to pivot it from the holding position into an actuation position, thereby unlocking the door.

[0003] US patent 2018 / 0148957A1 discloses a vehicle door device according to the preamble of claim 1. BRIEF EXPLANATION OF THE INVENTION

[0004] However, with this technique, the occupant has to perform two steps to unlock the door. The occupant must first push and then pull the outside handle to unlock the door. Therefore, there is still room for improvement in simplifying the door unlocking process.

[0005] The invention provides a vehicle door device that can simplify the process of releasing a lock when opening a door body.

[0006] A vehicle door device according to a first aspect of the invention comprises the features listed in claim 1.

[0007] In the configuration described above, the latch mechanism provided on the door body is switchable between the locked state, in which the latch mechanism engages the catch to prevent the door body from opening, and the unlocked state, in which the latch mechanism is released from the catch, so that opening of the door body is not prevented when the door body is closed. The door handle provided on the door body is movable between the first position, in which the outer surface of the door handle is flush with the outer surface of the door body, and the second position, in which at least part of the door handle projects towards the outside of the vehicle relative to the door handle in the first position, such that the person operating the door can grip the door handle.The door handle protrusion mechanism moves the door handle from the first position to the second position when the pressure section, located on the outer surface or edge of the door handle, is pressed. The switch of the electric release mechanism is actuated by the door handle or the door handle protrusion mechanism when the pressure section is pressed. The electric actuator of the electric release mechanism is thus activated to switch the latch mechanism from the locked to the unlocked position. As described above, the operator can therefore switch the latch mechanism from the locked to the unlocked position in a single step, in particular by simply pressing the pressure section.

[0008] The vehicle door device according to the first aspect of the disclosure may further comprise: a mechanical unlocking actuation mechanism designed to switch the latch mechanism, together with a predetermined movement of the door handle, from the locked state to the unlocked state.

[0009] With the configuration described above, the mechanical release mechanism, together with the predetermined movement of the door handle, switches the latch mechanism from the locked to the unlocked state. Accordingly, the operator can switch the latch mechanism from the locked to the unlocked state even in the event of a power failure.

[0010] In the vehicle door device according to the first aspect of the disclosure, the door handle can be moved into a third position when it is actuated from a second position in a direction in which the door body is opened, or in an opening direction of the door body, wherein the third position is further outwards towards the vehicle than the second position, and the mechanical unlocking actuation mechanism can be designed to switch the latch mechanism together with the movement of the door handle from the locked state to the unlocked state when the latch mechanism is in the locked state and the door handle is moved from the second position to the third position.

[0011] When the door handle is operated from the second position in the opening direction of the door body, the door handle, in the configuration described above, moves to the third position, which is the position facing outwards from the vehicle, corresponding to the second position. If the latch mechanism is in the locked state and the door handle is moved from the second to the third position, the mechanical release mechanism switches the latch mechanism from the locked to the unlocked state in conjunction with the movement of the door handle. Accordingly, the operating force is limited at the moment the door handle moves from the first to the second position. Furthermore, the operating force is also reduced at the moment the door handle moves from the second to the third position if no power failure has occurred.

[0012] In the vehicle door device according to the first aspect of the invention, the door handle has a U-shape that is open upwards or to a side viewed from the front of the door, and is designed to be movable between the first position and the second position when it is pivoted about an axis of a first pin that extends through both ends of the U-shape in a direction in which the two ends are opposite each other. The door handle projection mechanism comprises a flap and a lever. Viewed from the front of the door, the flap is arranged within the U-shape of the door handle, has a base section through which the first pin passes, and pivots about the axis of the first pin.The flap has a pressure plate and a projecting section, the pressure plate extending from the base section to the underside of the U-shaped door handle and having the pressure plate on its outer surface, and the projecting section extending from the base section to the inside of the door. The pressure plate is designed so that, when not pressed, it can be aligned with the door handle in its first position by a spring preload. The flap is designed to pivot, and when the pressure plate is pressed, the projecting section actuates the switch of the electric release mechanism.The lever, viewed along the axis of the first pin, has a V-shape, with its first end contacting an inner surface of the pressure plate and its second end contacting an inner surface of the underside of the U-shaped door handle. It is designed to pivot an axis of a second pin, which is parallel to the first pin and positioned closer than a bend at its first end. The lever is designed such that its first end can be pressed through the pressure plate, allowing the lever to pivot accordingly, and its second end pushes the door handle into the second position when the pressure plate is pressed, allowing the handle to pivot accordingly.

[0013] With the configuration described above, the U-shaped door handle, open upwards or to a side visible from the door front, is movable between the first and second positions when the handle is pivoted about the axis of the first pin, which runs through both ends of the U-shape in the opposite direction. The door handle projection mechanism includes a flap located within the U-shape of the door handle, as viewed from the door front. The flap encompasses the base section through which the first pin passes, allowing it to pivot about the axis of the first pin. The flap includes the pressure plate and the projection section. The pressure plate extends from the base section to the underside of the U-shape of the door handle and has the pressure section on its outer surface. The projection section extends from the base section toward the inside of the door.The pressure section is designed so that, when not pressed, it is aligned with the door handle in its first position by the spring's preload. When the pressure section is pressed, the flap pivots, and the projecting section actuates the switch of the electric release mechanism.

[0014] Furthermore, the door handle protrusion mechanism comprises a lever that, viewed from the axis of the first pin, has a V-shape. The lever has one end that contacts the inner surface of the pressure plate and a second end that contacts the inner surface of the underside of the U-shaped part of the door handle, and can pivot around the axis of the second pin. The second pin is positioned parallel to the first pin such that it is closer than the bend at the first end. When the pressure plate is pressed and the flap is pivoted accordingly, the first end of the lever is pushed through the pressure plate and the lever is pivoted accordingly, causing the second end of the lever to push the door handle into the second position. The operator can thus easily hold the underside of the U-shaped part of the door handle after pressing the pressure plate.

[0015] As described above, according to the vehicle door device, each aspect of the invention can simplify the actuation to remove a restriction when opening the door body. BRIEF EXPLANATION OF THE DRAWINGS

DETAILED EXPLANATION OF THE EXECUTIONAL FORMS First form not belonging to the invention

[0017] A vehicle door device according to a form of description not belonging to the invention, also referred to briefly as the "first form", is now described on the basis of the Fig. Figures 1 to 11B are described. In these figures, an arrow HI points rearward (i.e., backward in the vehicle's longitudinal direction), an arrow OB points upward (i.e., upward in the vehicle's vertical direction), and an arrow AUS points outward (i.e., outward in the vehicle's width direction). The directions used in the following description refer to a closed state of a side door 20.

[0018] Fig. Figure 1 is a schematic side view of a part of an automobile 12 in which a vehicle door device 10 of the present form is installed. As shown in the figures, the automobile 12 has a side door 20. The front end of the side door 20 is pivotally connected to an A-pillar 16A of a body 16 by means of a pair of upper and lower hinges 14. The body 16 has a door opening 16H on its side, so that an occupant can enter or exit the automobile 12 through the door opening 16H. The side door 20 can open and close the door opening 16H.

[0019] The side door 20 comprises a door body 22, a door frame 24, and a door trim panel (not shown). The door frame 24 serves as a window frame and is connected to the upper part of the door body 22. The door trim panel is attached to the inside of the door body 22 within a passenger compartment. The door body 22 comprises a metallic outer door panel 22A and an inner door panel (not shown). The outer door panel 22A forms an outer plate of the door body 22, located on the outside in the vehicle width direction, while the inner door panel forms an inner plate of the door body 22, located on the inside in the vehicle width direction. The outer door panel 22A extends in the vehicle height and length directions. Viewed from above, the outer door panel 22A has a convex horizontal cross-section. In particular, the outer door panel 22A is curved in such a way that its front orThe central section of the door panel 22A, viewed from the front of the vehicle, curves outwards in the longitudinal direction of the vehicle and in the width direction of the vehicle when viewed from above. The outer door panel 22A also has a convex longitudinal section when viewed from the front. In particular, the outer door panel 22A is curved such that its central section, viewed from the front, curves outwards in the vertical direction of the vehicle and in the width direction of the vehicle. The inner door panel (not shown) extends in the vertical and longitudinal directions of the vehicle, with its front, rear, and lower ends being connected to the front, rear, and lower ends of the outer door panel 22A by means of folds. This creates an interior space within the door body 22.

[0020] Fig. Figure 2 is a perspective view showing a schematic configuration of the vehicle door device 10 according to the aforementioned shape, as seen from the inside of the door. As in Fig. As shown in Figure 2, the vehicle door device 10 has a latch mechanism 30 on the inside of the door body 22. For a better understanding of the configuration of the latch mechanism 30, the latch mechanism 30 and its edge section are shown in Figure 2. Fig. 2 shown enlarged. As in Fig. As shown in Figure 1, the latch mechanism 30 is arranged at the rear end of the door body 22 in the longitudinal direction of the vehicle and has a base element 32 (shown schematically in the figure) which is attached to the door body 22. The latch mechanism 30 further has a locking device or latch 34, which is engaged by the base element 32 via a Fig. The bearing pin S1 shown in Figure 2 (where only the central axis of the bearing pin S1 is shown in the figure) is supported. The bearing pin S1 is arranged such that its axis runs in the longitudinal direction of the vehicle. The pawl 34 can be positioned between a Fig. 3B shown locked or locking position 34X and one in Fig. The unlocked or unlocked position 34Y shown in 9B is rotated around the bearing pin S1. The pawl 34 is held in the position shown in 9B by a spring (not shown). Fig. 9B shown unlock position 34Y pre-tensioned (see arrow D).

[0021] As in Fig. As shown in 3B, the latch 34 has an engagement recess 34A for catching a trap 18 (see Fig. 1) As in Fig. As shown in Figure 1, the trap 18 is attached to a B-pillar 16B of the body 16. Although not shown in the figure, the trap 18 has a U-shape when viewed from above. The one shown in Fig. The latching mechanism 30 shown in Figure 2 can be switched between a locked state and an unlocked state, or change position, when the Fig. 1. The door body 22 shown is in a closed state. When the latch mechanism 30 is in the locked state, the latch 34 is in the locking position 34X (see Figure 1). Fig. 3B), engages the latch 18 on the body side and prevents the door body 22 from opening. When the latch mechanism 30 is in the unlocked state, the latch 34 is in the unlocked position 34Y (see Fig. 9B), does not engage the trap 18 and does not prevent the door body 22 from opening.

[0022] As in Fig. As shown in Figure 2, the latch 34 has a stop section 34B, which is formed in the form of a recess on its outer circumference. When the latch 34 engages in the catch 18 (see Figure 2) Fig. 3B), the stop section 34B abuts an outer stop section 36A1 of a first arm 36A of a bolt 36, thereby stopping the rotation of the latch 34. The outer stop section 36A1 is part of the free end of the first arm 36A, which projects upwards.

[0023] The bolt 36 is connected via a bearing pin S2 (of which only the central axis is shown in the figure) through the base element 32 (see Fig. 1) carried. The bearing pin S2 is arranged such that its axis runs in the longitudinal direction of the vehicle. The bolt 36 is between a in the Fig. 2 to 3B shown locking position 36X and one in the Fig. In the unlocking position 36Y shown in sections 8 to 11B, the bolt 36 can be rotated around the bearing pin S2. The bolt 36 is held in the position shown in section 8 to 11B by a spring (not shown). Fig. The locking position 36X shown in 3 B is pre-tensioned (see arrow R1). The bolt 36 operates with a [unclear] in Fig. The door body 22 shown in Figure 2 is joined to the door handle 40 (also referred to as the "outer handle"). When the door handle 40 is actuated, the bolt 36 is moved into the unlocked position 36Y (see Figure 2). Fig. 8 and Fig. 10) swung.

[0024] Fig. Figure 4 is a horizontal section showing the door handle 40 in a stowed or initial state. The door handle 40 can be positioned in either a... Fig. 4 shown first position 40X and one in Fig. The second position 40Y shown in Figure 5 can be moved. When the door handle 40 is in the first position 40X, its outer surface 40A is flush with an outer surface 22B of the door body 22. When the door handle 40 is in the second position 40Y, part of it protrudes towards the outside of the vehicle relative to the door handle 40 in the first position 40X, so that the person operating it can hold it. As shown in Figure 5, the door handle 40 can be moved to the second position 40Y. Fig. As shown in Figure 1, the door handle 40 is arranged so that its longitudinal direction runs horizontally when viewed from the front of the door. As shown in the Fig. 4 and Fig. As shown in Figure 5, the door handle 40 is rotatable between the first position 40X and the second position 40Y when the door handle 40 is pivoted about the axis of a pin 42 extending vertically along the door. The door handle 40 is held in the position 40Y by a spring 46 (e.g., a torsion spring). Fig. The first position shown in section 4 is pre-tensioned 40X (see arrow 46R).

[0025] As in Fig. As shown in Figure 1, the pin 42 is arranged in a forward position in the longitudinal direction of the vehicle along the door handle 40, i.e., viewed from the front of the door along the longitudinal direction of the door handle on one side 40, the position being not at one end in the longitudinal direction of the door handle 40. A pressure section 40P is, as shown in Fig. Figure 1 shows a pressure section 40P located at the front end of the outer surface 40A of the door handle 40, in the longitudinal direction of the vehicle (the end of the outer surface 40A of the door handle 40 that is located on one side in the longitudinal direction of the door handle 40). The pressure section 40P is used to release the door handle 40 from the area shown in Figure 1. Fig. 4 shown first position 40X into the in Fig. 5 to move to the second position 40Y shown. In particular, the vehicle door device 10 of the present form has a door handle extension mechanism or door handle protrusion mechanism 44, which moves the door handle 40 out of the position shown in Fig. 4 shown first position 40X into the in Fig. The second position shown in section 5, 40Y, pivots when the pressure section 40P is pressed. The direction in Fig. 5, into which the pressure section 40P is pressed, is represented by the arrow P.

[0026] As in Fig. As shown in Figure 4, the door handle 40 has a projecting section 40Q on the inside of the door. The projecting section 40Q is formed on a portion of the inner surface of the door handle 40 that is located near the front end of the door handle 40 in the longitudinal direction of the vehicle (i.e., near the end of one side in the longitudinal direction of the door handle 40). The projecting section 40Q has a curved surface 40B on its upper surface. The curved surface 40B is concave towards the outside of the door. The projecting section 40Q further has an inclined surface 40C on its rear side in the direction of the vehicle. The inclined surface 40C extends towards the inside of the door and is slightly inclined towards the front of the vehicle.

[0027] As in Fig. As shown in Figure 2, the vehicle door device 10 has an electric unlocking actuation mechanism 50 that causes the latch 36 to be actuated together with the door handle 40. The electric unlocking actuation mechanism 50 has a switch 52 located opposite the projection section 40Q of the door handle 40. The switch 52 is connected to an ECU (shown as a block in the figure, also referred to as the "control unit") 54. The switch 52 is configured to output an actuation signal when it is pressed. An electric motor 56, acting as an electric actuator for unlocking, is connected to the control unit 54. When the switch 52 is pressed, the control unit 54 actuates the electric motor 56 according to the actuation signal from the switch 52.

[0028] A first gear (or worm gear) 58 is coaxially mounted on an output shaft of the electric motor 56. A second gear (or worm gear) 60 is arranged such that its axis runs in the vehicle width direction, with the first gear 58 engaging with the second gear 60. The second gear 60 has a larger diameter than the first gear 58. The second gear 60 has teeth 60T on its outer circumferential surface and a pin-like projection 60A on its side surface. The projection 60A is designed such that its axis runs in the vehicle width direction. The projection 60A contacts the upper surface of a first arm 62A of a lever 62. The lever 62 is connected via a bearing pin S3 (only its central axis of which is shown in the figure) through the base element 32 (see Fig. 1) is mounted and can be rotated about it. The bearing pin S3 is arranged such that its axis runs in the direction of the vehicle width. The lever 62 has a second arm 62B which extends in the opposite direction to the first arm 62A. The lower surface of the free end of a second arm 36B of the bolt 36 touches the upper surface of the free end of the second arm 62B. The second arm 36B of the bolt 36 extends in the opposite direction to the first arm 36A of the bolt 36.

[0029] As in the Fig. 9A and Fig. As shown in Figure 9B, when the electric motor 56 is actuated, the first gear 58 and the second gear 60 are rotated, causing the projection 60A to push the first arm 62A of the lever 62 downwards and simultaneously the second arm 62B of the lever 62 to push the second arm 36B of the bolt 36 upwards. When the second arm 36B of the bolt 36 is pushed upwards, the first arm 36A of the bolt 36 moves downwards, so that the outer stop section 36A1 of the first arm 36A of the bolt 36 is released from the stop section 34B of the latch 34. When the outer stop section 36A1 of the first arm 36A of the bolt 36 has been released from the stop section 34B of the latch 34, the latch 34 is rotated into the unlocked position 34Y by the preload force of the (not shown) spring (see arrow D).

[0030] The electric release actuation mechanism 50 is configured as follows. If the pressure section 40P (see Fig. 2) When pressed, the switch 52 is actuated by the projection section 40Q on the inner surface of the door handle 40. The electric motor 56 is then actuated and the latch mechanism 30 is switched from the locked state to the unlocked state.

[0031] As in Fig. As shown in section 6, the door handle 40 is designed to move into a third position 40Z when it is moved from the second position 40Y (see Fig. 5) is actuated in the opening direction of the door body 22 (see arrow R). The third position 40Z comprises one corresponding to the second position 40Y (see Fig. 5) Position on the outside of the vehicle. As in Fig. As shown in Figure 2, the vehicle door device 10 has a mechanical unlocking actuation mechanism 70 which causes the door handle 40 and the bolt 36 to be mechanically actuated together.

[0032] The mechanical unlocking actuation mechanism 70 has a crank mechanism 72 on the inside of the door handle 40. Viewed in the vehicle width direction, the crank mechanism 72 has an L-shape, with a first arm 72B and a second arm 72C extending from a base section 72A of the crank mechanism 72. The crank mechanism 72 is supported by the door body 22 via a bearing pin S4 extending through the base section 72A (only its central axis being shown in the figure). The bearing pin S4 is positioned such that its axis runs in the vehicle width direction. The crank mechanism 72 can be operated from a Fig. 7A shown starting position 72X and one in Fig. The actuation position 72Y shown in 7B is rotated around the bearing pin S4. The crank mechanism 72 is pre-tensioned towards the initial position 72X by a spring 74 for the crank mechanism 72 (e.g. a torsion coil spring) (see arrow 74R).

[0033] If the door handle 40 is in the Fig. When the first position 40X shown in Figure 4 is located, the first arm 72B of the crank mechanism 72 is away from the inclination surface 40C of the inner surface of the door handle 40. When the door handle 40 is in the position shown in Fig. When the door handle 40 is in the second position 40Y shown in Figure 5, the first arm 72B touches the inclined surface 40C. Fig. When the third position 40Z shown in 6 is located, the first arm 72B is pushed or pressed through the inclined surface 40C (see arrow A).

[0034] As in Fig. As shown in Figure 2, a free end 76A is part of the rod 76 and is curved towards the outside of the door. The free end 76A passes through the free end of the second arm 72C of the crank mechanism 72 in such a way that the rod 76 can rotate about the axis of the free end 76A in the vehicle width direction. The rod 76 has a long middle or intermediate section 76B, which extends downwards towards the rear of the vehicle, and a lower part 76C, which is curved like a crank or crank-like from the lower end of the intermediate section 76B.

[0035] The lower part 76C of the rod 76 passes through a ring section 78R of a lever 78 with a ring (hereinafter simply referred to as "lever 78"). The ring section 78R is formed at the free end of a first arm 78A of the lever 78, the lever 78 being arranged such that the lower part 76C of the rod 76 passes through the ring section 78R in the vehicle height direction. The lever 78 has a second arm 78B on the side opposite the first arm 78A and a bent section 78C at the free end of the second arm 78B. The bent section 78C is bent obliquely upwards in the vehicle height direction and inwards in the vehicle width direction. The bent section 78C is arranged directly below the second arm 36B of the bar 36. The lever 78 is connected via a bearing pin S5 (only its central axis is shown in the figure) through the base element 32 (see Fig. 1) is mounted and can rotate around it. The bearing pin S5 is arranged so that its axis runs in the longitudinal direction of the vehicle.

[0036] If the door handle 40 is removed from the in Fig. 5 shown second position 40Y into the in Fig. When the third position 40Z shown in 6 is pivoted, the inclined surface 40C of its inner surface pushes the in Fig. 10. Crank mechanism 72 shown, so that the crank mechanism 72 is rotated and the rod 76 is moved downwards. When the rod 76 is moved downwards, it pushes the ring section 78R of the into the Fig. 11A and Fig. The lever 78 shown in Figure 11B moves downwards, causing the lever 78 to rotate (see arrow B). The bending section 78C of the lever 78 then pushes the second arm 36B of the bolt 36 upwards, causing the bolt 36 to rotate (see arrow C). The first arm 36A of the bolt 36 is then moved downwards, releasing its outer stop section 36A1 from the stop section 34B of the latch 34. Once the outer stop section 36A1 of the first arm 36A of the bolt 36 has been released from the stop section 34B of the latch 34, the latch 34 is rotated into the unlocked position 34Y by the spring (not shown) (see arrow D).

[0037] When the latch mechanism 30 is in the locked position and the door handle 40 is in the second position 40Y (see Fig. 5) into the third position 40Z (see Fig. 6) when moved, the switch in Fig. 2 The mechanical release actuation mechanism 70 shown above, as described above, moves the latch mechanism 30 together with the movement of the door handle 40 from the locked state to the unlocked state, as shown in Fig. 10 is shown.

[0038] The functions and effects of the present form are now described below.

[0039] When pressure section 40P is pressed, which is located in Fig. The outer surface 40A of the door handle 40 shown in 1 is provided, which moves in Fig. 2 The door handle projection mechanism 44 shown in the present form extends the door handle 40 from the in Fig. 4 shown first position 40X into the in Fig. The second position 40Y shown in Figure 5. Simultaneously, the switch 52 is actuated by the projection section 40Q formed on the inner surface of the door handle 40. The electric motor 56 of the in Fig. The electrical release actuation mechanism 50 shown in Figure 8 is then actuated to switch the latching mechanism 30 from the locked state to the unlocked state. As described above, the actuating person can move the latching mechanism 30 from the locked state to the unlocked state by a single step, i.e., by simply pressing the pressure section 40P (see Figure 8). Fig. 1) switch.

[0040] The following describes the operation of the electric release mechanism 50. If the Fig. When the electric motor 56 shown in 9A is actuated, the first gear (the worm shaft) 58 is rotated, whereupon the second gear (the worm gear) 60 is rotated accordingly (see arrow 60R), its projection 60A pushing the first arm 62A of the lever 62 downwards. The lever 62 is thereby rotated (see arrow 62R), and its second arm 62B pushes the second arm 36B of the latch 36 upwards. As in Fig. As shown in Figure 9B, the bolt 36 is rotated (see arrow 36R) when the second arm 36B of the bolt 36 is pushed upwards. The first arm 36A of the bolt 36 is therefore moved downwards, and the outer stop section 36A1 of the first arm 36A of the bolt 36 is released from the stop section 34B of the latch 34. At this point, the latch 34 is rotated by the preload force of the (not shown) spring into the unlocked position 34Y (see arrow D), thereby releasing it from the catch 18.

[0041] As in Fig. As shown in Figure 1, in the present form the door handle 40 is arranged such that its longitudinal direction, viewed from the front of the door, runs horizontally. The door handle 40 can be positioned between the position shown in Figure 1. Fig. 4 shown first position 40X and the one in Fig. The second position 40Y shown in Figure 5 can be moved when it is pivoted about the axis of the pin 42 running in the vertical direction of the door. As shown in Figure 5, the pin can be moved to the second position 40Y when it is pivoted about the axis of the pin 42 running in the vertical direction of the door. Fig. As shown in Figure 1, the pin 42 is arranged longitudinally along the door handle 40 such that it is located at the front in the longitudinal direction of the vehicle, i.e., viewed from the front of the door, longitudinally along the door handle on one side 40, but not at the end longitudinally along the door handle 40. The pressure section 40P is provided longitudinally along the front end of the outer surface 40A of the door handle 40 (the end of the outer surface 40A of the door handle 40 that is located longitudinally along the door handle 40 on one side). The Fig. The door handle projection mechanism 44 shown pivots the door handle 40 from the first position 40X into the position shown. Fig. 5. Second position 40Y shown when pressure section 40P is pressed. As shown in the Fig. 2 and Fig. As shown in Figure 4, the switch 52 is the electrical release actuation mechanism 50 (see Figure 4). Fig. 2) arranged so that it faces the inner surface (projection section 40Q) of the front end of the door handle 40 in the longitudinal direction of the vehicle (the end of the door handle 40 that is located on one side in the longitudinal direction of the door handle 40). Despite the simple configuration, this is achieved as in Fig. As shown in Figure 5, switch 52 is activated when the in Fig. 4 etc. shown pressure section 40P is pressed.

[0042] As described above, according to the vehicle door device 10 of the present form, actuation to remove a restriction on the opening of the door body 22 can be simplified.

[0043] After the operator has removed the restriction on opening the door body 22, they can hold the door handle 40 to open the door body 22 or a rim 22Z of an opening for the door handle 40 in which the door handle 40 is positioned to open the door body 22. Thus, the present form offers flexibility in operation by the operator.

[0044] In its present form, the door handle 40 is inserted into the Fig. The third position 40Z shown in Figure 6 moves when it is actuated from the second position 40Y in the opening direction of the door body 22, with the third position 40Z being located on the outside of the vehicle compared to the second position 40Y. When the Fig. 2 the latch mechanism 30 shown is in the locked state and the door handle 40 is in the second position 40Y (see Fig. 5) into the third position 40Z (see Fig. 6) is moved, the mechanical release actuation mechanism 70 switches as in Fig. Figure 10 shows the latch mechanism 30 together with the movement of the door handle 40 from the locked state to the unlocked state. Accordingly, the person operating the latch mechanism 30 can switch it from the locked state to the unlocked state even if a power failure occurs.

[0045] The following describes the operation of the mechanical unlocking actuation mechanism 70. When the door handle 40 is removed from the Fig. 5 shown second position 40Y into the in Fig. When the third position 40Z shown in Figure 6 is pivoted, the inclined surface 40C of the inner door surface presses against the crank mechanism 72, so that the crank mechanism 72 is as shown in Figure 6. Fig. 10 is shown being rotated. Thus, the rod 76 is moved downwards. When the rod 76 is moved downwards, its lower part 76C pushes the ring section 78R of the lever 78 downwards, so that the lever 78, as shown in the Fig. 11A and Fig. As shown in Figure 11B, the lever 78 is rotated (see arrow B). Thus, the bending section 78C of the lever 78 pushes the second arm 36B of the bolt 36 upwards, so that the bolt 36 is rotated (see arrow C). Simultaneously, the first arm 36A of the bolt 36 is moved downwards. In this way, the outer stop section 36A1 of the first arm 36A of the bolt 36 is released from the stop section 34B of the latch 34. When the outer stop section 36A1 of the first arm 36A of the bolt 36 is released from the stop section 34B of the latch 34, the latch 34 is rotated by the preload force of the (not shown) spring into the unlocked position 34Y (see arrow D), so that it is released from the catch 18.

[0046] At the time the door handle 40 is moved from the in Fig. 4 shown first position 40X into the in Fig. In the second position 40Y shown in section 5, the operating load is limited. Furthermore, at the moment the door handle 40 is moved from the second position 40Y into the position shown in section 5, the operating load is limited. Fig. The third position shown, 40Z, also limits the actuating load if no power failure has occurred. embodiment

[0047] The following describes a vehicle door device according to one embodiment of the description based on the Fig. Described in sections 12A to 13B. Fig. 12A and Fig. Figure 12B shows a vehicle door device 80 of the present embodiment with a door handle 82 in an initial state. Fig. 13A and Fig. Figure 13B shows the vehicle door device 80 with a pressed flap 92. The flap 92 forms an edge section of the door handle 82. The configuration of the present embodiment is, with the exception of the aspects described below, essentially the same as that of the first embodiment. The components that are essentially the same as those of the first embodiment are identified by the same reference numerals, and their descriptions are omitted.

[0048] The one in the Fig. 12A and Fig. The door handle 82 shown in Figure 12B has a U-shape, open at the top when viewed from the front of the door. The door handle 82 is positioned between a first position 82X and a second position 82Y (see Figure 12B). Fig. 13A and Fig. 13B) movable when it is about the axis of a first pin 84 (where in Fig. 12B (only its central axis is shown) is pivoted, which extends through two ends 82A, 82C of the U-shape in a direction in which the two ends 82A, 82C are opposite each other. When the door handle 82 is in the first position 82X, its outer surface 82S is flush with the outer surface 22B of the door body 22. When the door handle 82 is in the second position 82Y, a part of it projects towards the outside of the vehicle relative to the door handle 82 in the first position 82X, such that the person operating it can hold it. The door handle 82 is moved towards the door body 22 by its spring (not shown). Fig. 12A and Fig. The first position shown in 12B is pre-tensioned to 82X.

[0049] As in Fig. As shown in Figure 12B, the door handle 82 has a projecting section 82D. The projecting section 82D extends from an upper end 82C on the rear of the vehicle and projects inwards towards the door. The free end 76A of the rod 76 is inserted through the projecting section 82D such that the rod 76 can pivot in the longitudinal direction of the vehicle about the axis of the free end 76A. A mechanical latching mechanism 88 of the present embodiment does not have the crank mechanism 72 of the Fig. The vehicle door device 80 shown in the first embodiment (2 etc.) does not have a structure that is essentially the same as the rod 76 and lever 78 of the mechanical unlocking actuation mechanism 70 of the first embodiment. Fig. 12A and Fig. The present embodiment shown in Figure 12B has a configuration that is essentially similar to the electric unlocking actuation mechanism 50 and the latching mechanism 30 of the embodiment shown in Figure 12B. Fig. 2 etc. shown in the first embodiment.

[0050] As in the Fig. 12A and Fig. As shown in Figure 12B, a door handle projection mechanism 90 of the present embodiment comprises the flap 92, which, viewed from the front of the door, is arranged within the U-shape of the door handle 82, and a lever 96, which is described in detail below. The flap 92 has a base section 92A through which the first pin 84 passes, so that the flap 92 can be pivoted about the axis of the first pin 84. Furthermore, the flap 92 has a pressure plate 92B and a projection section 92C. The pressure plate 92B extends from the base section 92A to a bottom surface 82B of the U-shape of the door handle 82 and has a pressure section 92P on its outer surface. The projection section 92C projects from the base section 92A toward the inside of the door. The pressure section 92P is located on an edge section of the outer surface 82S of the door handle 82. The pressure section 92 is designed so that it is preloaded by a spring 94 (e.g.a torsion coil spring) is aligned with the door handle 82 in the first position 82X (see arrow 94R) when the pressure section 92P is not pressed. The switch 52 contacts the upper surface of the projection section 92C. The flap 92 is designed such that when the pressure section 92P is pressed, the flap 92 pivots and the projection section 92C actuates the switch 52 of the electric release actuation mechanism 50 (see . Fig. 13A and Fig. 13B).

[0051] The lever 96 is essentially V-shaped when viewed in the axial direction of the first pin 84. The lever 96 is arranged such that its first end 96A contacts an inner surface 92Q of the pressure plate 92B and its second end 96C contacts an inner surface 821 of the underside 82B of the U-shape of the door handle 82. The lever 96 can pivot about the axis of a second pin 98 (with only its central axis in Fig. (as shown in Figure 12B), wherein the first pin 84 is arranged parallel to the first pin and is located closer to the first end 96A than to a bend 96B. The flap 92 is rotated when the pressure section 92P is pressed. As the flap 92 is rotated, the pressure plate 92B pushes the first end 96A of the lever 96. In this way, the lever 96 is pivoted so that its second end 96C pushes the door handle 82 into the second position 82Y (see Figure 12B). Fig. 13A and Fig. 13B).

[0052] As described above, the door handle projection mechanism 90 of the present embodiment moves the door handle 82 from the first position 82X to the second position 82Y (see Fig. 13A and Fig. 13B), when pressure section 92P of flap 92 is pressed.

[0053] When the pressure section 92P of the flap 92 is pressed, the flap 92 of the door handle projection mechanism 90 is pivoted according to the present embodiment, so that the switch 52 of the electric release actuation mechanism 50 is activated as shown in Fig. 13A and Fig. Figure 13B shows that the flap 92 is actuated by the projecting section 92C. As in the first embodiment, the person operating the flap can thus switch the latching mechanism from the locked state to the unlocked state in a single step, i.e., by simply pressing the pressure section 92P.

[0054] In the present embodiment, the flap 92 is pivoted when the pressure section 92P is pressed. When the flap 92 is pivoted, the pressure plate 92B pushes the first end 96A of the lever 96. In this way, the lever 96 is pivoted so that its second end 96C pushes the door handle 82 into the second position 82Y. The operator can thus, after pressing the flap 92, simply hold the underside 82B of the U-shape of the door handle 82.

[0055] In the present embodiment, the rod 76 is moved downwards when the operator presses the pressure section 92P and the door handle 82 is moved into the second position 82Y. Therefore, the operator can switch the latch mechanism from the locked state to the unlocked state even if a power failure has occurred. Modifications of the embodiments

[0056] In a modification of the one in the Fig. In the first form shown in Figures 1 to 11B, the pin provided at the pivot point of the door handle can be arranged such that it is located at the rear of the vehicle and at the rear of the door handle, i.e., viewed from the front of the door, at one end of the door handle and at the other end, but not at the end. In this modification, the pressure section is located at the rear end of the outer surface of the door handle (the end of the outer surface of the door handle that is at one end of the door handle), and the switch of the electric unlocking mechanism is arranged so that it is opposite the inner surface of the rear end of the door handle in the vehicle's longitudinal direction (the end of the door handle that is at one end of the door handle).

[0057] In a modification of the one in the Fig.In the embodiment shown in 12A to 13B, the door handle can have a U-shape that is open to one side as seen from the front of the vehicle and can be moved between a first position and a second position when it is pivoted about the axis of a first pin that extends through both ends of the U-shape in the direction in which the ends are opposite each other.

[0058] In another modification of the embodiment, the door handle (82) can be configured to move into a third position, which includes a position on the outside of the vehicle relative to the second position (82Y), when it is actuated from the second position (82Y) in the opening direction of the door body (22). The mechanical release actuation mechanism can be configured such that the distance between the ring section (78R) of the lever (78) and the part of the rod (76) that pushes the ring section (78R) of the lever (78) downwards is greater than in the first and second embodiments. Thus, when the latch mechanism (30) is in the locked state and the door handle (82) is moved from the second position (82Y) to the third position, the mechanical release actuation mechanism can be configured to switch the latch mechanism (30) from the locked state to the unlocked state together with the movement of the door handle (82).

[0059] In a further modification of the embodiment, a door handle can be used instead of the door handle 82. This door handle is positioned similarly to the position of the underside 82B of the door handle 82 (in other words, in a position where the second end 96C of the lever 96 contacts the underside 82B) and is not pivoted, but rather moved forward toward and away from the door body (22). This door handle can be moved between a first position and a second position by moving forward toward and away from the door body (22). When the door handle is in the first position, its outer surface is flush with the outer surface (22B) of the door body (22). When the door handle is in the second position, it projects toward the outside of the vehicle relative to the door handle in the first position, such that the person operating it can grip it.In this case, the door handle can be designed to move into a third position on the outside of the vehicle when it is actuated from the second position in the opening direction of the door body (22). Furthermore, the vehicle door device can be configured such that the direction of the actuating force is changed when the latch mechanism (30) is in the locked state and the door handle is moved from the second position to the third position, so that the rod (76) moves downwards together with the movement of the door handle and the latch mechanism (30) is switched from the locked state to the unlocked state.

[0060] The above forms, designs and modifications can be combined as needed.

[0061] Although examples of the invention have been described above, it should be noted that the invention is not limited to these and various modifications can be made without deviating from the field and scope of the invention.
