Description

[Technical Field]

[0001] The present invention relates to a vehicle door closing restriction device and a vehicle door device. [Background technology]

[0002] Conventionally, vehicles with sashless doors have weatherstripping attached to the periphery of the door opening, and when the door glass is closed, the upper edge of the door glass is enveloped by the weatherstripping, providing waterproofing and soundproofing effects (see, for example, Patent Document 1).

[0003] In such vehicles, when the door is closed while the door glass is in the fully closed position, the door glass may come into contact with the weatherstrip and be damaged. Therefore, in such vehicles, the door control device that controls the raising and lowering of the door glass performs slight lowering control to slightly lower the door glass below the fully closed position when the door is opened or closed, preventing the door glass from coming into contact with the weatherstrip.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-82808 Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, vehicles have become known in which door control devices electronically control the entire door. However, these door control devices may malfunction due to program updates or a power outage from the vehicle's power supply. In such a situation, if a user wants to open or close the door, they can do so using an emergency unlocking mechanism, such as an external cylinder or an internal emergency handle. However, if the door control device is not operating, the door glass opening and closing control also stops, preventing the door glass from slightly lowering. Consequently, the door is opened or closed with the door glass remaining fully closed. The door glass is attached to the door with its tip tilted toward the weatherstrip rather than perpendicular to the door opening direction. When the door is opened, the weatherstrip elastically deforms, allowing the door glass to pass through the weatherstrip and open. However, when the door is closed, the edge of the door glass strikes the weatherstrip in the compressed direction, preventing the door glass from passing through the weatherstrip and potentially resulting in damage.

[0006] The present invention provides a door closing restriction device and a vehicle door device that can protect the door glass even when the door control device is not operating. [Means for solving the problem]

[0007] The present invention comprises the following configurations. A door closing restriction device provided on a vehicle door to restrict closing of the door, a stopper provided on a door edge portion of the door so as to be able to appear and disappear; an operating unit provided on the door; a transmission unit that transmits an operating force of the operation unit to the stopper; Equipped with The stopper is caused to protrude from the door edge portion when the operating portion is operated. Door closing control device. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a door closing restriction device and a vehicle door device that can protect the door glass even when the door control device is not operating. [Brief explanation of the drawings]

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the arrow FR indicates the front of the vehicle, the arrow BC indicates the rear of the vehicle, the arrow UP indicates the top of the vehicle, the arrow DW indicates the bottom of the vehicle, the arrow WR indicates the right of the vehicle, and the arrow WL indicates the left of the vehicle.

[0011] Fig. 1 is a perspective view of a door 1 equipped with a close-door restriction device 100 according to this embodiment. Fig. 2 is a schematic diagram of the door 1 equipped with the close-door restriction device 100 according to this embodiment, viewed from inside.

[0012] 1 and 2, a door closing restriction device 100 according to this embodiment is provided on a door 1 of a vehicle. The door closing restriction device 100 includes a stopper 10, an operation unit 20, and a transmission unit 30. The door 1 further includes a door lock device (not shown) that holds the door in a closed position, a lifting device (not shown) that raises and lowers the door glass 2, a door control unit (not shown) that controls the door lock device and the lifting device, a door switch (not shown) that opens the door 1, and a detection unit (not shown) that detects the open / closed state of the door 1, which constitute a door device.

[0013] The door 1 on which the door closing restriction device 100 is installed is connected to the vehicle at the front FR side and is rotatable relative to the vehicle at this connection point. The door 1 opens and closes the opening of the vehicle by rotating at the connection point. The door 1 is, for example, a sashless door without a window frame, and in the closed state, the periphery of the door glass 2, which is provided on the door 1 so as to be able to rise and fall, is enclosed by a weather strip provided around the periphery of the opening of the vehicle. In such a vehicle, when a user operates the door switch to open the door 1, the door control unit controls the lifting device to lower the door glass 2, thereby releasing the engagement between the door glass 2 and the weatherstrip. The door control unit also controls the door lock device to release the door closed hold, allowing the door to open. Furthermore, when the detection unit detects that the door has transitioned from an open state to a closed state, the door control unit drives the lifting device to engage the door glass 2 with the weatherstrip.

[0014] The stopper 10 of the door closing restriction device is provided on the door edge 3 on the side of the door 1 opposite to the side connected to the vehicle. The stopper 10 is formed, for example, from an elastic material, and is provided so as to be able to appear and disappear from the door edge 3. The door closing restriction device may also be configured as a door opening / closing control device such as a door check.

[0015] Fig. 3 is a schematic cross-sectional view of the door edge 3 taken along the horizontal direction when the stopper 10 is stored. Fig. 4 is a schematic cross-sectional view of the door edge 3 taken along the horizontal direction when the stopper 10 is protruded.

[0016] As shown in FIGS. 3 and 4 , the stopper 10 has a connecting portion 11 and a restricting portion 12. The restricting portion 12 is connected to the connecting portion 11 of the stopper 10, and the stopper 10 is formed in a substantially U-shape in a plan view. An end of the connecting portion 11 of the stopper 10 is supported by a support shaft 10a relative to the door 1 so as to be rotatable about an axis in the vertical direction. By rotating the stopper 10 relative to the door 1, the stopper 10 is positioned at a stored position (position in FIG. 3 ) stored inside the door 1 and at a protruding position (position in FIG. 4 ) where the restricting portion 12 protrudes from an end surface 3a of the door edge portion 3. Note that in this embodiment, the stopper 10 is described as being provided so as to be retractable into the door edge portion 3 on the side opposite the side where the door 1 is connected to the vehicle; however, the stopper 10 may be retractable into, for example, the lower end of the door edge portion 3.

[0017] Fig. 5 is a schematic diagram of the operation unit 20 and the transmission unit 30 that constitute the close door restriction device 100. Fig. 6 is a perspective view of the operation unit 20 and the transmission unit 30 that constitute the close door restriction device 100.

[0018] As shown in FIGS. 5 and 6 , the operating unit 20 has a grip portion 21 and an action portion 22. The action portion 22 extends laterally from an end of the grip portion 21, thereby forming the operating unit 20 in an L-shape in a plan view. The operating unit 20 has a rotation shaft 23 at a portion where the grip portion 21 and the action portion 22 are connected, and is supported by the rotation shaft 23 so as to be rotatable about an axis in the vertical direction relative to the door 1. The grip portion 21 of the operating unit 20 is exposed inside the door 1, and a user grasps the grip portion 21 of the operating unit 20 and rotates it in the rotation direction Ra. In this way, the operating unit 20 can be operated from inside the door 1. Although not shown, the operating unit 20 is connected to a door lock device by a wire or the like and functions as an emergency door handle that can release the latch of the door lock device when the user rotates the operating unit 20 in the rotation direction Ra.

[0019] The transmission unit 30 includes a rod 31 and a link 32. The rod 31 is formed in a long, rod-like shape and is disposed along the vehicle longitudinal direction. The rod 31 is supported so as to be movable along the longitudinal direction. One end 31a of the rod 31 is connected to one end 32a of a link 32 by a pin 32b. The link 32 is formed in an L-shape bent at its middle portion, and its bent portion 32c is supported by a pin 32d so as to be rotatable about an axis in the vehicle width direction. The other end 32e of the link 32 abuts against a side surface 22a of the action portion 22 of the operation unit 20 on the grip portion 21 side. The other end 31b of the rod 31 is connected to the connection portion 11 of the stopper 10 by a pin 31c (see FIGS. 3 and 4). The transmission unit 30 also includes a cam mechanism 40 near the other end 31b of the rod 31. The rod 31 is divided into an operating side rod 35 on the operating part 20 side and a stopper side rod 36 on the stopper 10 side, and the cam mechanism 40 is provided between the operating side rod 35 and the stopper side rod 36 (see Figures 2 to 4).

[0020] FIG. 7 is a schematic diagram of the cam mechanism 40. As shown in FIG. As shown in FIG. 7 , the cam mechanism 40 includes a heart cam 41. The heart cam 41 has a cam groove 42 and a cam pin 43. The cam groove 42 is a heart-shaped groove, and the cam pin 43 is movable relative to the cam groove 42. The heart cam 41 has one end connected to the operating-side rod 35 and the other end connected to the stopper-side rod 36. A connecting portion 46 having an elongated hole 45 is provided at one end of the heart cam 41 to which the operating-side rod 35 is connected, and the connecting end 35a of the operating-side rod 35 is movable within the range of the elongated hole 45. In addition, a recessed portion 48 in which a coil spring 47 is housed is provided at the other end of the heart cam 41 to which the stopper-side rod 36 is connected.

[0021] The cam groove 42 of the heart cam 41 has a standby position P1, a first push-out position P2, a holding position P3, and a second push-out position P4. In the heart cam 41, the standby position P1 is located at the other end where the stopper-side rod 36 is connected, and the first push-out position P2 and the second push-out position P4 are located at one end where the operation-side rod 35 is connected. In addition, in the heart cam 41, the holding position P3 is located between the first push-out position P2 and the second push-out position P4, and is located closer to the standby position P1 than the first push-out position P2 and the second push-out position P4.

[0022] In the door 1 equipped with the closing-door restriction device 100 having the above structure, when the user operates the operating unit 20 in an open state, the stopper 10, which is in the storage position stored inside the door 1, rotates, and the restriction part 12 is positioned in a protruding position protruding from the end surface 3a of the door edge 3. Then, even if an attempt is made to close the door 1 in this state, the restriction part 12 of the stopper 10 interferes with the vehicle door frame, such as a pillar, and restricts the door from closing. As a result, even when the door glass 2 of the door 1 is closed, interference of the door glass 2 with the weatherstrip is avoided, and the door glass 2 is protected. Furthermore, when the user operates the operating unit 20 again, the closing-door restriction device 100 retracts the stopper 10, which is positioned in the protruding position, into the door 1 and is positioned in the storage position. As a result, the restriction on the door 1 from closing is released, and the door 1 can be closed.

[0023] Next, a specific operation of the door closing restriction device 100 when the user operates the operation unit 20 will be described. 8 to 11 are schematic diagrams each illustrating the movement of the cam mechanism 40. FIG.

[0024] (When door closing is controlled) The user grips the grip portion 21 of the operating unit 20 and rotates the operating unit 20 in the rotation direction Ra (see FIG. 6). This causes the door lock device to be operated via a wire (not shown) to release the door lock, and the action portion 22 of the operating unit 20 rotates the link 32 of the transmission unit 30 in the rotation direction Rb (see FIG. 6). The rod 31 of the transmission unit 30, connected to the link 32, moves toward the rear of the vehicle BC toward the stopper 10. This rotates the stopper 10 from the storage position, and the restricting portion 12 of the stopper 10 is positioned at a protruding position protruding from the end surface 3a of the door edge portion 3, placing the door 1 in a door-close restricted state (see FIG. 4). Also, as shown in FIG. 8, in the cam mechanism 40, the heart cam 41 is pushed out by the connecting end 35a of the operating-side rod 35, and the cam pin 43, which was positioned at the standby position P1, moves to the first pushing position P2.

[0025] In this state, when the user releases his / her grip on the grip portion 21 of the operating unit 20, the heart cam 41 is released from being pushed out by the connecting end 35a of the operating-side rod 35, and the cam pin 43 moves to and is held at the holding position P3, as shown in Figure 9. This keeps the heart cam 41 pushed out toward the stopper 10. Therefore, the stopper 10 is kept in a state where the restricting portion 12 is positioned at a protruding position protruding from the end face 3a of the door edge portion 3, and keeps the door 1 in a closed state where the door 1 is restricted from closing.

[0026] (When door closing restriction is released) With the door 1 open, the user grips the grip portion 21 of the operating unit 20 and rotates the operating unit 20 in the rotation direction Ra (see FIG. 6). Then, the action portion 22 of the operating unit 20 rotates the link 32 of the transmission unit 30 in the rotation direction Rb (see FIG. 6), and the rod 31 of the transmission unit 30 connected to the link 32 moves toward the rear of the vehicle BC toward the stopper 10.

[0027] Then, as shown in FIG. 10, in the cam mechanism 40, the heart cam 41 is pushed out again by the connecting end 35a of the operating side rod 35, and the cam pin 43 disposed at the holding position P3 moves to the second pushing position P4.

[0028] In this state, when the user releases his / her grip on the grip portion 21 of the operating unit 20, the heart cam 41 is released from the connecting end 35a of the operating-side rod 35, and the cam pin 43 moves to the standby position P1 (see FIG. 7). This causes the heart cam 41 to be retracted to the side opposite the stopper 10. Therefore, the stopper 10, which is in the protruding position, is placed in the stored position stored inside the door 1, and the stopper 10's restriction on the door 1 from closing is released.

[0029] Even if the door lock device is released by operating the operating unit 20, the door 1 may not rotate in the opening direction, and the door-closing restriction operation may be performed with the door 1 closed. Even if the user grips the gripping portion 21 of the operating unit 20 and rotates the operating unit 20 in the rotation direction Ra while the door 1 is closed, the heart cam 41 of the cam mechanism 40 is pushed out by the connecting end 35a of the operating-side rod 35, and the cam pin 43, which was located at the standby position P1, moves to the first pushing position P2, and then moves to the holding position P3 when the gripping portion 21 is released. However, in this case, as shown in FIG. 11 , the movement of the stopper 10 is restricted by the door frame of the vehicle, and the pushing force on the stopper 10 is absorbed by the contraction of the coil spring 47 provided in the recessed portion 48 of the cam mechanism 40.

[0030] As explained above, by installing the door closing restriction device 100 of this embodiment on the door 1 of a vehicle, the user can activate the door closing restriction device 100 to cause the stopper 10 to protrude from the door edge portion 3, so that even if the user attempts to close the door 1, the stopper 10 will interfere with the door frame of the vehicle, restricting the door from closing and protecting the door glass 2.

[0031] Here, in a vehicle equipped with a door control device that electronically controls the locking and unlocking of door 1, there is a risk that the door control device may not be operating due to a program update or a power cut-off from the vehicle power supply for some reason.

[0032] Even in such a situation, if the door closing restriction device 100 is provided, the closing of the door 1 can be restricted, and therefore, particularly in vehicles with sashless doors, damage to the door glass 2 caused by closing the door 1 in a closed state can be suppressed.

[0033] In addition, the device is equipped with a cam mechanism 40 that alternates between an extrusion state in which the stopper 10 is extended and a retraction state in which the stopper 10 is retracted by operating the operating unit 20, so that the protrusion operation of the stopper 10 and the retraction operation of the stopper 10 can be easily performed by operating the operating unit 20.

[0034] Next, a description will be given of a closing door restriction device 200 according to another embodiment. Note that the same structural parts as those of the above-described closing door restriction device 100 are given the same reference numerals and the description thereof will be omitted. FIG. 12 is a schematic diagram of the structure of a door 1 equipped with a close-door restriction device 200 according to another embodiment, as viewed from the outside.

[0035] 12, a door close restriction device 200 according to another embodiment is provided with an operating unit 50 on the exterior panel of the door 1. This operating unit 50 is made up of a cylinder, and can be operated by the user inserting a key into it and turning it. In this way, the operating unit 50 can be operated from the outside of the door 1.

[0036] The operating unit 50 has an arm 51, and the rod 31 of the transmission unit 30 is connected to the end of the arm 51. As a result, in the close door restriction device 200, when the user rotates the operating unit 50 using the inserted key, the rod 31 of the transmission unit 30 moves along the longitudinal direction, and the door 1 is restricted from closing by the stopper 10 and the door closing restriction is released. In this way, in the close door restriction device 200, the door 1 can be restricted from closing and the door closing restriction can be released from the outside of the door 1.

[0037] In addition, a door-closing restriction device 100 having an operating unit 20 on the inside of the door 1 may be combined with a door-closing restriction device 200 having an operating unit 50 on the outside of the door 1, in which case the door-closing restriction operation and the release of the door-closing restriction can be performed from both the inside and outside of the door 1.

[0038] In another embodiment, the door closing restriction device may be installed on a door that can be electrically opened and closed under normal circumstances using a switch or a sensor. In this case, the door 1 is configured as a vehicle door device including a lifting device that lifts and lowers the door glass 2, a door locking device that can hold the door 1 in a closed state, a door control unit that controls the lifting device and the door locking device, a first operation unit that can send a control signal to the door control unit to release the door closed state when a user operates a switch or sensor to open the door 1 under normal circumstances, a second operation unit that is mechanically connected to the door locking device and mechanically releases the door closed state when a user operates the door to open the door in an emergency, etc., and a door close restriction device that restricts the door 1 from closing. The door close restriction device does not restrict the door 1 from closing when it accepts the operation of the first operation unit, but restricts the door 1 from closing when it accepts the operation of the second operation unit. The door close restriction device may be a stopper 10 as in the above embodiment, or it may be configured to restrict movement of the door drive unit in the door closing direction or to restrict movement in the door closing direction by a door check.

[0039] As such, the present invention is not limited to the above-described embodiments, and the present invention also contemplates the mutual combination of the various components of the embodiments, as well as modifications and applications by those skilled in the art based on the description in the specification and well-known techniques, and these modifications and applications are included in the scope of protection sought.

[0041] According to the door closing restriction device of [1] above, when the operating part is operated while the door is open, the stopper protrudes from the door edge, so even if an attempt is made to close the door, the stopper interferes with the door frame of the vehicle, restricting the door from closing and protecting the door glass. This makes it possible to prevent a deterioration in the quality of the door glass in vehicles with sashless doors from occurring when the door with the door glass in the closed state is closed.

[0042] [2] The transmission unit is equipped with a cam mechanism that alternates between an extrusion state in which the stopper is extended and a retraction state in which the stopper is retracted by operation of the operating unit. This is a door closing restriction device described in [1].
