Abstract
Description
Technical Field
[0001] This invention relates to a door closing restriction device for vehicles and a vehicle door device. Background Technology
[0002] In the past, in vehicles with frameless doors, weatherstripping was installed around the door opening. When the door glass was closed, the upper edge of the door glass was surrounded by the weatherstripping, which provided waterproofing and sound insulation (for example, see Patent Document 1).
[0003] In such vehicles, if the door is closed with the glass fully closed, the glass will come into contact with the weatherstripping, potentially causing it to break. Therefore, in these vehicles, the door control device that regulates the raising and lowering of the door glass performs a slight descent control when the door is opened and closed, lowering the glass slightly below the fully closed position to prevent contact between the glass and the weatherstripping.

[0007] In recent years, vehicles have been known to have door control devices that electronically control the entire door system. These door control devices sometimes malfunction due to program updates or power outages caused by certain conditions. In such situations, users can open or close the doors using external lock cylinders or emergency unlocking units such as the interior emergency handle. However, when the door control device is not activated, the opening and closing control of the door glass also stops, resulting in the door being opened and closed with the glass fully closed without proper glass descent control. The door glass is mounted to the door in an orientation perpendicular to the door's opening and closing direction, tilting towards the weatherstripping at its top. Therefore, when the door is opened, the weatherstripping elastically deforms, allowing the door to open while the glass passes through it. However, when the door is closed, the edge of the door glass protrudes in the direction of weatherstripping compression, potentially preventing the glass from passing through and causing breakage. Summary of the Invention
[0008] This 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 in operation.
[0009] The present invention comprises the following components.
[0010] A door closing restriction device, disposed on a vehicle door, restricts the closing of the door, comprising:
[0011] A stop is provided on the edge of the door and configured to move between a retracted position inside the door and a protruding position protruding from the edge of the door.
[0012] An operating unit is located at the vehicle door; and
[0013] The transmission unit transmits the operating force of the operating unit to the stop member.
[0014] The stop is configured to the protruding position by being operated by the operating part.

[0037] Hereinafter, examples of embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that in the following drawings, arrow FR indicates the front of the vehicle, arrow BC indicates the rear of the vehicle, arrow UP indicates the top of the vehicle, arrow DW indicates the bottom of the vehicle, arrow WR indicates the right side of the vehicle, and arrow WL indicates the left side of the vehicle.
[0038] Figure 1 This is a perspective view of a car door 1 equipped with a door closing restriction device 100 according to this embodiment. Figure 2 This is a schematic configuration diagram of the vehicle door 1 equipped with the door closing restriction device 100 in this embodiment, viewed from the inside.
[0039] like Figure 1 and Figure 2 As shown, the door closing restriction device 100 of this embodiment is provided on the vehicle door 1. The door closing restriction device 100 includes a stop member 10, an operating part 20, and a transmission part 30. The vehicle door 1 also includes a door locking device (not shown) for holding the door in a closed position, a lifting device (not shown) for raising and lowering the door glass 2, a door control unit (not shown) for controlling the door locking device and the lifting device, a door switch (not shown) for opening the door 1, and a sensing unit (not shown) for sensing the opening and closing state of the door 1, thus constituting a door device.
[0040] The door 1, equipped with a door closing restriction device 100, is connected to the vehicle at the front FR side, and its connection part is designed to rotate relative to the vehicle. The door 1 opens and closes the opening of the vehicle by rotating the connection part. The door 1 is, for example, a frameless door without a window frame. In the closed state, the periphery of the door glass 2, which is provided in a liftable manner, is surrounded by a weatherstripping provided at the periphery of the opening of the vehicle.
[0041] In such a vehicle, when a user operates the door switch to open door 1, the door control unit controls the lifting device to lower the door glass 2, releasing the door glass 2 from the weatherstripping. The door control unit also controls the door to open by releasing the door locking device from the door closing hold. Furthermore, when the sensing unit detects that the door has moved from the open state to the closed state, the door control unit actuates the lifting device to engage the door glass 2 with the weatherstripping.
[0042] The stop 10 of the door closing restriction device is provided on the door edge 3 on the side opposite to the vehicle connection side of the door 1. The stop 10 is made of, for example, an elastic material and is provided on the door edge 3 in a recessable manner. It should be noted that the door closing restriction device may also be configured as a door opening limiter or other door opening and closing control device.
[0043] Figure 3 This is a schematic cross-sectional view along the horizontal direction of the door edge 3 with the stop 10 retracted. Figure 4 It is a schematic cross-sectional view along the horizontal direction of the door edge 3 with the stop 10 protruding.
[0044] like Figure 3 and Figure 4 As shown, the stop 10 has a connecting portion 11 and a limiting portion 12. The limiting portion 12 is connected to the connecting portion 11 of the stop 10, forming a roughly U-shape when viewed from above. In the stop 10, the end of the connecting portion 11 is supported by a support shaft 10a, allowing it to rotate about a vertical axis relative to the door 1. This stop 10 is configured to be stored inside the door 1 by rotating relative to the door 1. Figure 3 The position of the limiting part 12 protruding from the end face 3a of the door edge part 3. Figure 4 (Position). It should be noted that in this embodiment, the stop member 10 is described as being provided in a way that allows it to be inserted or removed from the door edge 3 on the side opposite to the vehicle connection side of the door 1. However, the stop member 10 may also be provided in a way that allows it to be inserted or removed from the lower side of the door edge 3.
[0045] Figure 5 This is a schematic diagram of the operation section 20 and the transmission section 30 that constitute the door closing restriction device 100. Figure 6This is a perspective view of the operating part 20 and the transmission part 30 that constitute the door closing restriction device 100.
[0046] like Figure 5 and Figure 6 As shown, the operating unit 20 has a gripping part 21 and an actuating part 22. The actuating part 22 extends laterally from the end of the gripping part 21, thus the operating unit 20 is formed in an L-shape when viewed from above. The operating unit 20 has a rotating shaft 23 at the connection between the gripping part 21 and the actuating part 22, through which the operating unit 20 is supported so that it can rotate about the vertical axis relative to the door 1. As for the operating unit 20, its gripping part 21 is exposed on the inside of the door 1, and is rotated in the rotation direction Ra by the user gripping the gripping part 21. In this way, the operating unit 20 can be operated from the inside of the door 1. It should be noted that, although not shown, the operating unit 20 is connected to the door locking device by a wire or the like, and functions as an emergency door handle that can open the latch of the door locking device as the user rotates in the rotation direction Ra.
[0047] The transmission unit 30 has a rod 31 and a connecting rod 32. The rod 31 is formed as a long bar and is arranged along the longitudinal direction of the vehicle. The rod 31 is supported so as to be movable along its length. One end 31a of the rod 31 is connected to one end 32a of the connecting rod 32 by a pin 32b. The connecting rod 32 is formed as an L-shape with a bend in the middle, and its bend 32c is supported by a pin 32d so as to be rotatable about the axis in the vehicle width direction. The other end 32e of the connecting rod 32 abuts against the side 22a of the gripping part 21 in the operating part 22 of the operating unit 20. The other end 31b of the rod 31 is connected to the connecting part 11 of the stop member 10 (see reference 11) by a pin 31c. Figure 3 and Figure 4 Furthermore, the transmission section 30 has a cam mechanism 40 near the other end 31b of the lever 31. The lever 31 is divided into an operating side lever 35 on the operating section 20 side and a stop side lever 36 on the stop 10 side, and the cam mechanism 40 is provided between the operating side lever 35 and the stop side lever 36 (see reference). Figures 2-4 ).
[0048] Figure 7 This is a schematic diagram of the cam mechanism 40.
[0049] like Figure 7The cam mechanism 40 includes a heart-shaped cam 41. The heart-shaped cam 41 has a cam groove 42 and a cam pin 43. The cam groove 42 is formed by a heart-shaped slot, and the cam pin 43 is movable relative to the cam groove 42. An operating rod 35 is connected to one end of the heart-shaped cam 41, and a stop rod 36 is connected to the other end. At one end of the heart-shaped cam 41 to which the operating rod 35 is connected, a connecting portion 46 with an elongated hole 45 is provided, and the operating rod 35 is configured such that its connecting end 35a can move within the range of the elongated hole 45. Furthermore, at the other end of the heart-shaped cam 41 to which the stop rod 36 is connected, a concave portion 48 is provided, which accommodates a coil spring 47.
[0050] The heart-shaped cam 41 has a cam groove 42 with a standby position P1, a first ejection position P2, a holding position P3, and a second ejection position P4. In the heart-shaped cam 41, the standby position P1 is located at the end connected to the stop rod 36, and the first ejection position P2 and the second ejection position P4 are located at the end connected to the operating rod 35. Furthermore, in the heart-shaped cam 41, the holding position P3 is located between the first ejection position P2 and the second ejection position P4, and is positioned closer to the standby position P1 than the first ejection position P2 and the second ejection position P4.
[0051] In the vehicle door 1 equipped with the door closing restriction device 100 described above, when the user operates the operating unit 20 while the door is open, the stop 10, which is stored in a retracted position inside the door 1, rotates, thereby positioning the restriction part 12 in a protruding position that protrudes from the end face 3a of the door edge 3. In this way, even if the door 1 is to be closed in this state, the restriction part 12 of the stop 10 will interfere with the vehicle door frame, such as a pillar, thus restricting the closing. Therefore, even if the door glass 2 of the door 1 is closed, interference with the weatherstripping of the door glass 2 is avoided, thereby protecting the door glass 2. Furthermore, when the user operates the operating unit 20 again, the stop 10, which has been positioned in the protruding position, is pulled back into the interior of the door 1, and the door closing restriction device 100 is positioned in the retracted position. This releases the restriction on closing the door 1, allowing the door 1 to close.
[0052] Next, the specific operation of the door closing restriction device 100 when the user operates the operation unit 20 will be explained.
[0053] Figures 8-11 These are schematic diagrams illustrating the operation of the cam mechanism 40.
[0054] (When the door is closed and operation is restricted)
[0055] The user holds the grip 21 of the operating unit 20, causing the operating unit 20 to rotate in the rotation direction Ra (see reference). Figure 6In this way, the door locking device is operated via a wire not shown to release the door holding, and the linkage 32 of the transmission unit 30 is rotated in the rotational direction Rb by the actuating part 22 of the operating part 20 (see reference). Figure 6 The rod 31 of the transmission part 30 connected to the linkage 32 moves toward the rear BC of the vehicle towards the stop 10. As a result, the stop 10 in the retracted position rotates and is positioned so that the limiting part 12 of the stop 10 protrudes from the end face 3a of the door edge 3, and the door 1 is in a closed and restricted state (see reference). Figure 4 In addition, such as Figure 8 As shown, in the cam mechanism 40, the heart-shaped cam 41 is pushed out by the connecting end 35a of the operating side rod 35, and the cam pin 43, which is configured in the standby position P1, will move to the first push-out position P2.
[0056] In this state, when the user releases the grip of the operating unit 20's gripping part 21, the push-out of the heart-shaped cam 41 by the connecting end 35a of the operating side lever 35 is released, such as... Figure 9 As shown, the cam pin 43 moves to and remains in the holding position P3. Thus, the heart-shaped cam 41 remains in the state of being pushed out towards the stop 10. Therefore, the stop 10 remains in the protruding position where the limiting part 12 is configured to protrude from the end face 3a of the door edge 3, thus maintaining a door-closing limiting state that restricts the closing of the door 1.
[0057] (When the door closure restriction is lifted)
[0058] With door 1 open, the user holds the handle 21 of the operating unit 20, causing the operating unit 20 to rotate in the rotation direction Ra (refer to...). Figure 6 In this way, the actuating part 22 of the operating part 20 causes the connecting rod 32 of the transmission part 30 to rotate in the rotational direction Rb (see reference). Figure 6 The rod 31 of the transmission part 30 connected to the linkage 32 moves toward the rear BC of the vehicle toward the stop member 10.
[0059] In this way, such as Figure 10 As shown, in the cam mechanism 40, the heart-shaped cam 41 is pushed out again by the connecting end 35a of the operating side rod 35, and the cam pin 43, which is already in the holding position P3, will move to the second push-out position P4.
[0060] In this state, when the user releases the grip of the operating unit 20's gripping part 21, the push-out of the heart-shaped cam 41 by the connecting end 35a of the operating side lever 35 is released, and the cam pin 43 moves towards the standby position P1 (refer to...). Figure 7As a result, the heart-shaped cam 41 is pulled in toward the opposite side of the stop 10. Therefore, the stop 10, which is configured in a protruding position, is stored in the interior of the door 1, thus releasing the door 1 from the closed state achieved by the stop 10.
[0061] It should be noted that sometimes, even if the door locking device is released by operating the operating unit 20, the door 1 does not rotate in the opening direction, and the door closing restriction operation is performed while the door 1 is closed. Thus, even if the door 1 is closed, and the user grips the grip 21 of the operating unit 20 to rotate the operating unit 20 in the rotation direction Ra, the heart-shaped cam 41 will be pushed out in the cam mechanism 40 via the connecting end 35a of the operating side lever 35. The cam pin 43, which is positioned in the standby position P1, will move to the first pushed-out position P2, and then move to the holding position P3 by releasing the grip of the grip 21. However, in this case, as... Figure 11 As shown, the stop 10 is restricted from moving by the vehicle door frame, so the coil spring 47 provided in the concave portion 48 of the cam mechanism 40 will contract, thereby absorbing the pushing force on the stop 10.
[0062] As described above, by providing the door closing restriction device 100 of this embodiment on the vehicle door 1, even if the user wants to close the door 1 by activating the door closing restriction device 100 to make the stop 10 protrude from the door edge 3, the stop 10 will interfere with the vehicle door frame to restrict the closing, thereby protecting the door glass 2.
[0063] In vehicles equipped with door control devices that electronically control the locking and unlocking of doors 1, the door control devices may become inoperable due to program updates, power supply interruptions caused by certain circumstances, or other reasons.
[0064] Even under such circumstances, if the door closing restriction device 100 is provided, the closing of the door 1 can be restricted. Therefore, especially in vehicles with frameless doors, damage to the door glass 2 caused by the door 1 being closed while the door glass 2 is in a closed state can be prevented.
[0065] Furthermore, the cam mechanism 40 is equipped with a cam mechanism that alternately and repeatedly pushes the stop 10 out in an extended state and pulls the stop 10 in an extended state by operating the operating part 20. Therefore, the operation of pushing out the stop 10 and the operation of retracting the stop 10 can be easily performed by operating the operating part 20.
[0066] Next, other embodiments of the door closing restriction device 200 will be described. It should be noted that the same reference numerals are used for structural parts that are the same as those in the door closing restriction device 100 described above, and their descriptions are omitted.
[0067] Figure 12 This is a schematic configuration diagram of a vehicle door 1 equipped with a door closing restriction device 200, as viewed from the outside, according to another embodiment.
[0068] like Figure 12 As shown, in another embodiment of the door closing restriction device 200, an operating section 50 is provided on the exterior panel of the door 1. This operating section 50 is composed of a lock cylinder and can be operated by the user inserting a key to turn it. In this way, the operating section 50 can be operated from the outside of the door 1.
[0069] The operating unit 50 has an arm 51, at the end of which a rod 31 of the transmission unit 30 is connected. Thus, in the door closing restriction device 200, the operating unit 50 is rotated by the key inserted by the user, causing the rod 31 of the transmission unit 30 to move along its length, performing the door closing restriction operation and releasing the door closing restriction, which is achieved by the stop member 10. Therefore, in the door closing restriction device 200, the door closing restriction operation and releasing the door closing restriction operation can be performed from the outside of the door 1.
[0070] It should be noted that the door closing restriction device 100, which has an operating part 20 on the inside of the door 1, can also be combined with the door closing restriction device 200, which has an operating part 50 on the outside of the door 1. In this case, the door closing restriction operation and the release of the door closing restriction can be performed from the inside and outside of the door 1.
[0071] In addition, as another implementation, the aforementioned door closing restriction device can also be installed on a vehicle door that can normally be opened and closed electrically by a switch or sensor.
[0072] In this configuration, the car door 1 is a vehicle door assembly comprising the following components: a lifting device that raises and lowers the door glass 2 in the same manner as described in the above embodiment; a door locking device that keeps the door 1 in a closed state; a door control unit that controls the lifting device and the door locking device; a first operating unit that, under normal circumstances, sends a control signal to the door control unit to release the door from the door locking device when the user performs an opening operation on the door 1 from a switch or sensor; a second operating unit that is mechanically connected to the door locking device and, in an emergency or other situation, mechanically releases the door from the door locking device when the user performs an opening operation on the door; and a door closing restriction device that restricts the closing of the door 1. Furthermore, the door closing restriction device does not restrict the closing of the door 1 when operated by the first operating unit, but restricts the closing of the door 1 when operated by the second operating unit. The door closing restriction device can be the same as the stop 10 in the above embodiment, or it can restrict the door closing direction movement of the door drive unit, or restrict the movement in the closing direction by a door opening limiter.
[0073] The door control unit has a processor and a non-transitory computer-readable storage medium storing a computer-readable program.
[0074] Therefore, the present invention is not limited to the above-described embodiments. Any modifications or applications of the various components of the embodiments by those skilled in the art, based on the description in the specification and well-known technologies, are also within the scope of the present invention and are included within the scope of the claims.
[0075] As described above, the following matters are recorded in this specification. [1] A door closing restriction device is provided on a vehicle door to restrict the closing of the door, comprising:
[0076] A stop is provided on the edge of the door in a retractable manner;
[0077] An operating unit is located at the vehicle door; and
[0078] The transmission unit transmits the operating force of the operating unit to the stop member.
[0079] The stop is protruded from the edge of the door by being operated by the operating part.
[0080] According to the door closing restriction device described above [1], when the operating unit is operated while the door is open, the stop protrudes from the edge of the door. Therefore, even if the door is to be closed, the stop will interfere with the door frame of the vehicle and restrict the closing, thereby protecting the door glass. Thus, in vehicles with frameless doors, the quality of the door glass can be suppressed from deteriorating due to the door being closed while the door glass is in a closed state.
[0081] [2] According to the door closing restriction device described in [1], the transmission part is provided with a cam mechanism, which alternately and repeatedly causes the stop to protrude into an extended state and the stop to be pulled in into an extended state by operating the operation part.
[0082] According to the door closing restriction device described above [2], the protrusion operation of the stop and the storage operation of the stop can be easily performed by operating the operating part.
[0083] [3] According to the door closing restriction device of [1] or [2], wherein the operating part is configured to be operable from at least one side of the door, both inside and outside.
[0084] According to the door closing restriction device described above [3], by operating the operating part on at least one side of the inner and outer sides of the door, the stop can be protruded from the edge of the door to restrict the door closing.
[0085] [4] A vehicle door device, comprising:
[0086] The vehicle door has a door glass that is configured to be raised and lowered and can be fitted with a weatherstripping provided in the vehicle opening at its highest position, and the door can be opened and closed relative to the vehicle opening.
[0087] A lifting device is used to raise and lower the door glass;
[0088] The door locking device can keep the door in the closed position;
[0089] The door control unit controls the lifting device and the door locking device;
[0090] The first operating unit can send a control signal to the door control unit in a manner that maintains the unlocked state relative to the door locking device when it receives a user's operation to open the door.
[0091] The second operating unit, mechanically connected to the door locking device, mechanically releases the door locking device from its closed state when the user opens the door; and
[0092] A door closing restriction device restricts the closing of the vehicle door.
[0093] The door closing restriction device does not restrict the closing of the door when operated by the first operating unit, but restricts the closing of the door when operated by the second operating unit.
[0094] According to the door device described above [4], in an electric door where the door is opened and closed by a switch and a sensor under normal circumstances, the door closing restriction device works during emergency operation (mechanical operation), thus preventing the quality of the door glass from deteriorating due to the user unintentionally closing the door when the door glass is in a closed state.
