Description

  The present invention relates to a vehicle door provided with a window glass.

  A window glass is attached to the window frame of the vehicle door so that it can be opened and closed. The window glass is a movable glass whose whole is movable. When the window glass is opened, the window glass passes through a gap formed at the lower edge of the window frame and falls into the door body.

  Recently, resin doors have been developed to reduce the weight of the vehicle body. Resin doors have the advantage that they are lightweight and easy to process, but have low rigidity. Therefore, a device for improving the safety at the time of a door collision has been devised. For example, as disclosed in Patent Document 1, there is a vehicle door in which a honeycomb structure is provided in the entire interior of a door body. The honeycomb structure is composed of a large number of cylindrical cells partitioned by partition walls. The partition walls extend inward and outward of the vehicle body, and have high rigidity against loads in the vehicle interior and exterior directions.

  However, if an internal structure for reinforcing strength such as a honeycomb is provided inside the door main body as in Patent Document 1, when the movable glass descends inside the door main body, it interferes with the internal structural body. For this reason, it has been difficult to add movable glass to a door provided with a reinforcing structure inside.

  Therefore, as shown in FIG. 17, Patent Document 2 proposes that a fixed glass 92 is fitted on one side of a window frame 90 of the door 9 and a movable glass 93 is provided on the other side. In Patent Document 2, the movable glass 93 is reduced by an amount corresponding to the area where the fixed glass 92 is provided, so that the amount of the movable glass 93 descending into the door body 95 can be reduced.

JP 2009-262916 A Japanese Patent Laid-Open No. 61-285117

  However, in Patent Document 1, when the movable glass 93 is opened, the movable glass 93 is lowered into the door 9. For this reason, even though the movable glass 93 is a part of the window glass and the amount of lowering can be reduced, it may interfere with the internal structure of the door 9.

  Further, even when a reinforcing structure such as a honeycomb is not provided inside the door 9, it is necessary to secure a space for the movable glass 93 descending inside the door body 95. For this reason, there is a restriction on the degree of freedom in designing the door.

  This invention is made | formed in view of this situation, and makes it a subject to provide the door for vehicles which can open and close a window glass smoothly and has high design freedom of a door.

  (1) A vehicle door according to the present invention is attached to a vehicle body so as to be openable and closable, and includes a door body and a window region covered with a window glass. The window glass is fixed to the door body. A fixed glass that covers a part of the window region; and a movable glass that is supported by the door body or the fixed glass so as to be openable and closable, and that covers the remainder of the window region. The movable glass is moved to an outer position outside the vehicle from the inner position so that the movable glass can be moved in the plane direction of the movable glass. A mechanism is provided.

  According to the said structure, the movable glass is hold | maintained at the inner position which forms a substantially identical surface with fixed glass at the time of closing. At the time of closing, the movable glass is moved to the outer position outside the vehicle body from the inner position, and can move in the plane direction of the movable glass. For this reason, the movable glass can move in the plane direction without entering the inside of the door body, and the window region can be opened. Therefore, it can prevent interfering with the internal structure of the door body.

  Further, regardless of whether or not the internal structure of the door body is provided, it is not necessary to provide a space for the movable glass to descend inside the door body, leading to saving of the internal space. In addition, the degree of freedom in designing doors will increase, leading to the creation of innovative designs.

  Only a part of the window region is covered with the movable glass. For this reason, compared with the case where the whole window area | region is made into movable glass, the weight of movable glass can be made comparatively light and the load added to an opening-and-closing mechanism at the time of movable glass movement can also be made small. Therefore, the movable glass can be easily moved.

  The “window region” refers to a region covered with a window glass. When the door frame is provided with a window frame, it refers to the area formed in the window frame, and when the door body does not have a window frame, the door when the vehicle door is closed An area formed between the main body and the vehicle body.

  (2) The opening / closing mechanism includes a base portion fixed to the inner side of the movable glass body, a support member having a support shaft protruding from the base portion to the vehicle inner side, and fixed to the door body so that the support shaft can be advanced and retracted. An accommodating member to be accommodated, accommodated inside the accommodating member, one end supported by the accommodating member, the other end supported by the support shaft, and the support so that the movable glass moves backward toward the inner position. An urging member that urges the shaft to the inside of the vehicle body, and is held by the base so as to be movable between an operating position and a non-operating position, and when positioned at the non-operating position, the supporting shaft is Retracting inward to position the movable glass at the inner position, and when positioned at the operation position, the movable glass moves forward toward the outer position against the biasing member. Move the support shaft to the outside of the vehicle It is preferable that and an operating member for.

  In this case, when the operation member is moved to the non-operation position, the support member having the support shaft is pulled into the vehicle body by the urging member. The movable glass fixed to the support member is urged toward the inside of the vehicle body, and is closed in a state where it is held at an inner position substantially on the same plane as the fixed glass.

  When the movable glass is opened from the closed state, the operating member is moved to the operating position, and the support member jumps out of the vehicle body against the urging member. The movable glass is moved to an outer position outside the vehicle body, can move in the plane direction, and can be opened.

  Thus, according to the above configuration, the movable glass can be opened and closed with a simple configuration without entering the inside of the door body, and the manufacturing cost can be reduced. Further, since the opening / closing mechanism is simple, it can be miniaturized, leading to a reduction in weight.

  (3) The edge portion of the surface of the movable glass that faces the inner side of the vehicle body and that engages with the edge portion of the fixed glass is the edge portion of the fixed glass when the movable glass is closed. It is preferable that a protrusion made of an elastic member that comes into contact with is provided. In this case, when the movable glass is closed, the elastic member fixed to the movable glass is in close contact with the fixed glass. For this reason, it is hard to produce a clearance gap between movable glass and fixed glass. Moreover, the play of the movable glass can be suppressed.

  (4) It is preferable that a resin frame is fixed to a portion of the movable glass that comes into contact with the protrusions at the edge of the fixed glass that comes into contact with the movable glass when the movable glass is closed. In this case, the protrusion of the movable glass is in elastic contact with the resin frame provided at the edge of the fixed glass. For this reason, the gap between the fixed glass and the movable glass can be further suppressed, and the play of the movable glass is also suppressed.

  According to the vehicle door of the present invention, when the movable glass is opened from the closed state, the movable glass can be moved in the plane direction by moving from the inner position where the movable glass is substantially flush with the fixed glass to the outer position outside the vehicle body. It is said. Therefore, the movable glass can be smoothly opened and closed without entering the inside of the door body, and the degree of freedom in designing the door is high.

  As shown in FIGS. 1 and 2, the window frame 2 is provided on the upper side of the door body 1. A window region 3 is formed inside the window frame 2. The window region 3 is a region covered with a window glass 30 including a fixed glass 31 and a movable glass 32.

  The door body 1 is made of an olefin resin or the like. The fixed glass 31 and the movable glass 32 are also resin glasses made of transparent resin, and the material thereof is polycarbonate (PC), acrylic resin (PMMA), or the like.

  The peripheral edge portion and the rear side portion of the front side portion of the window region 3 are covered with the fixed glass 31. The lower edge of the fixed glass 31 is fitted to the upper edge of the door body 1, and the front edge, the upper edge, and the rear edge of the fixed glass 31 are formed on the outer surface of the window frame 2 facing the vehicle body by two-color molding or insert. It is fixed by molding.

  An opening 31a is formed on the front side of the fixed glass 31, and this opening 31a corresponds to the “remaining part of the window region 3” of the present invention. A resin frame 33 is fixed to the entire edge of the opening 31a. The resin frame 33 is made of, for example, ABS resin, polypropylene, polycarbonate, or the like. As shown in FIG. 4, the cross section of the resin frame 33 is substantially T-shaped, is fitted to the fixed glass 31 on the outer peripheral surface, and is in contact with the movable glass 32 when closed on the inner peripheral surface. The fixed glass 31 and the resin frame 33 are integrally formed by two-color molding or insert molding.

  The movable glass 32 covers an opening 31a formed in the fixed glass 31 so that it can be opened and closed. On the inner side surface of the movable glass 32 facing the inner side of the vehicle body, a protrusion 34 is projected. The protrusion 34 is continuously provided on the entire periphery of the inner surface of the movable glass 32. As shown in FIG. 5, the protrusion 34 has a hemispherical shape and is made of a rubber material (elastic member). A step portion 32c slightly lower than the general plane portion 32b is formed on the inner side surface of the entire peripheral edge of the movable glass 32, and a protrusion 34 is fixed to the step portion 32c by two-color molding or insert molding. An undercut portion 32d is formed in the standing wall portion between the step portion 32c and the general plane portion 32b. The undercut portion 32 d is fitted with a protrusion 34 a that protrudes the bottom of the protrusion 34 toward the inner peripheral side, thereby preventing the protrusion 34 from coming off the movable glass 32.

  When the movable glass 32 is closed, the protrusion 34 is in contact with the resin frame 33 fixed to the fixed glass 31. The portion where the ridge 34 abuts on the resin frame 33 is the tip 34 b of a semi-spherical portion protruding toward the inner peripheral side of the ridge 34.

  The resin frame 33 fixed to the fixed glass 31 and the protrusion 34 fixed to the movable glass 32 are preferably the same color from the viewpoint of appearance. Further, the vicinity 32e of the step portion 32c of the general flat surface portion 32b of the movable glass 32 may be painted with the same color as the ridge 34 in terms of appearance. For example, when the resin frame 33 is manufactured using black polycarbonate, the protrusion 34 may be black, and the vicinity 32e of the step portion 32c of the general flat portion 32b of the movable glass 32 may be painted black.

  The movable glass 32 is opened and closed by the opening / closing mechanism 5. As shown in FIGS. 6 and 7, the opening / closing mechanism 5 includes a support member 51, a storage member 52, an urging member 53, and an operation member 54.

  The support member 51 is fixed at a relatively lower position on the surface of the movable glass 32 facing the vehicle body. The support member 51 integrally includes a base 51a that movably accommodates the operation member 54, and a support shaft 51b that protrudes inward from the side wall of the base 51a. The base 51a is a long frame, and the bottom is open. The bottom of the base 51a is covered with a cover 51j. The base 51a is disposed so as to extend in the longitudinal direction of the vehicle body, and is fixed to the movable glass 32 by means such as adhesion, screw fastening, and insert molding.

  An operation member 54 and a spring 55 are accommodated in the base 51a. One end of the spring 55 is locked to the side of the operation member 54, and the other end is locked to a convex portion 51h protruding from the inner side surface of the base 51a (FIG. 7). The spring 55 is biased in a direction in which the operation member 54 moves toward the one end side with respect to the base portion 51a.

  After accommodating the operation member 54 and the spring 55 in the base 51a, the cover 51j is formed in a groove extending in the longitudinal direction formed on the inner surface near the bottom of the side wall from the other end on the side where the support shaft 51b is disposed. Engage and slide toward one end. A standing wall 51g bent at the rear end of the cover 51j is brought into contact with the other end of the base 51a.

  One end portion of the operation member 54 in the longitudinal direction protrudes outward from the base portion 51a, and an operation portion 54a is provided at the tip. The other end portion in the longitudinal direction of the operation member 54 is formed with a tapered portion 54b that is inclined in a direction of gradually narrowing the width toward the tip. The tapered portion 54b is formed on the wall surface of the other end portion of the operation member 54 facing the vehicle body.

  The support shaft 51b protrudes from the wall surface facing the inner side of the vehicle body on the other end side in the longitudinal direction of the base 51a toward the inner side of the vehicle body. As shown in FIG. 9, a through hole 51c having a circular cross section that communicates with a space in the base 51a is formed on the base end side of the support shaft 51b. Further, a step portion 51d is formed in the middle portion of the support shaft 51b in the axial direction so as to increase the width of the accommodating portion 52a toward the inside of the vehicle body. Washers 51e and 51f are attached to the support shaft 51b, and one of the washers 51e is engaged with the step portion 51d of the support shaft 51b so as to be detachable. The other washer 51f is integrally fixed to the support shaft 51b by being engaged with an engagement claw 51m protruding from the end face of the tip of the support shaft 51b. A biasing member 53 is provided between the washer 51e and the washer 51f. The biasing member 53 is a coil spring, and has one end pressed against the end face of the washer 51e and the other end pressed against the end face of the washer 51f, thereby biasing the support shaft 51b in the direction of retreating toward the inside of the vehicle body. ing. One end of the urging member 53 is supported by the housing member 52, and the other end is supported by the support shaft 51b.

  The housing member 52 is fixed to the upper edge of the door body 1 by screw fastening. The housing member 52 is disposed near the boundary between the fixed glass 31 and the movable glass 32. Inside the accommodating member 52, an accommodating portion 52a penetrating in the inner and outer directions of the vehicle body is formed. A support shaft 51b is inserted into the accommodating portion 52a from the outside of the vehicle body so as to freely advance and retract. The cross section of the housing portion 52a outside the vehicle body is a non-circular cross section 52b and has a shape corresponding to the non-circular cross section 51k formed on the base end side of the housing shaft 51b of the support member 51. The support shafts 51b can be inserted into the housing portion 51a when the directions of the support shafts 51b match each other, and are not inserted into the housing portion 51a when the directions of the support shafts 51b do not match.

  When the movable glass 32 is closed, the support shaft 51b is positioned at the innermost side of the housing 51a, that is, the rear side. At this time, the stepped portion 51d of the support shaft 51b has substantially the same axial position as the stepped washer contact portion 52c formed on the inner peripheral surface of the accommodating portion 52a.

  Further, a cap 52e is fitted to the opening periphery of the housing portion 52a inside the vehicle body. After the support shaft 51b is inserted into the housing portion 52a from the outside of the vehicle body, the washer 51e, the biasing member 53, and the washer 51f are sequentially inserted from the opening inside the vehicle body of the housing portion 52a, and these are attached to the support shaft 51b. Finally, the opening inside the vehicle body of the accommodating part 51a is closed with the cap 52e.

  As shown in FIGS. 6 and 7, a cylindrical pin 52d is inserted into a through hole 51c formed on the base end side of the support shaft 51b. The through hole 51c has a circular shape corresponding to the shape of the pin 52d. One end of the pin 52d on the inner side of the vehicle body is slidably in contact with the end surface of the housing member 52 on the outer side of the vehicle body, and the other end of the pin 52d on the outer side of the vehicle body can be moved back and forth in the internal space of the base 51a of the support member 51. It protrudes.

  Next, the operation of the vehicle door of the present embodiment will be described. As shown in FIG. 7, when the movable glass 32 is closed, the movable glass 32 is positioned on the same plane as the fixed glass 31. Here, “on the same plane as the fixed glass 31” means not only the case where the plane of the movable glass 31 and the plane of the fixed glass 32 form a single continuous plane without a step, but also the movable glass 32 and the fixed glass. This includes the case where there is a slight difference to the extent that the boundary between 31 is fitted to each other. As shown in FIG. 4, the protrusion 34 protruding from the movable glass 32 is made of an elastic member and is in elastic contact with the resin frame 33 of the fixed glass 31. As shown in FIGS. 7 and 9, when the movable glass 32 is closed, the operation member 54 is retracted toward one end of the base 51 a, and the pin 52 d in contact with the housing member 52 is a taper of the operation member 54. It is located at the front end side of the portion 54b or at a position away from the tapered portion 54b. The support shaft 51b is located on the innermost side of the housing portion 52a of the housing member 52, that is, on the inner side of the vehicle body.

  As shown in FIGS. 8 and 10, when the movable glass 32 is opened from the closed time, the operation portion 54a of the operation member 54 is pushed toward the base portion 51a. The operation member 54 advances to the other end side of the base portion 51a, and the tapered portion 54b of the operation member 54 is pressed against the tip of the pin 52d and gradually moves to the outside of the vehicle body. Along with this, the support member 51 holding the operation member 54 moves to the outside of the vehicle body. The movable glass 32 jumps out from the inner position to the outer position outside the vehicle body as the support member 51 moves outside the vehicle body.

  As the support member 51 moves to the outside of the vehicle body, one washer 51e is held by the washer contact portion 52c of the housing member 52, and the other washer 51f moves to the outside of the vehicle body together with the support shaft 51b of the support member 51. As a result, the distance between the washer 51e and the washer 51f is reduced, and the urging member 53 held therebetween is compressed and the urging force is accumulated.

  When the fixed glass 31 and / or the movable glass 32 is a flat plate, the movable glass 32 is moved from the inner position on the same plane as the fixed glass 31 to the outside of the vehicle body by at least the thickness of the fixed glass 31. The position moved to the outside of the vehicle body is the outside position. When the fixed glass 31 and / or the movable glass 32 are curved in the vehicle interior / exterior direction, the outer position of the movable glass 32 extends from the inner position to the vehicle body outer side at least in addition to the thickness of the fixed glass 31. It is good to set it as the position which moved by the protrusion of glass 31 and 32. Preferably, the outer position of the movable glass 32 is moved to such a degree that there is a slight gap between the movable glass 32 and the fixed glass 31 in order to prevent contact with the fixed glass 31 when the movable glass 32 overlaps the fixed glass 31. It is good to be in the position.

  As shown in FIGS. 12, 13, and 14, when the movable glass 32 moves to the outer position, the operation member 54 is rotated upward while pressing the operation portion 54 a. The movable glass 32 and the support member 51 are rotated together with the operation member 54 so that a portion covered with the movable glass 32 in the window region 3 is opened. When the support member 51 rotates, the through hole 51c revolves around the central axis of the support shaft 51b. Accordingly, the pin 52d inserted into the through hole 51c also revolves around the central axis of the support shaft 51b while slidingly contacting the end surface of the housing member 52 on the outer side of the vehicle body. During this time, the tip of the pin 52d outside the vehicle body maintains contact with the operation member 54. Further, as the support member 51 rotates, the orientation of the non-circular cross section 51k of the support shaft 51b does not match the orientation of the non-circular cross section 52b outside the vehicle body of the housing portion 52a of the housing member 52. The section 52b is rotated while maintaining the state where the section 52b is pulled out. Therefore, the support member 51 stays with the movable glass 32 at an outer position outside the vehicle body than the fixed glass 31.

  As shown in FIGS. 12 and 14, when the operation member 54 is rotated about 90 °, the side wall of the base 51 a is formed in a plate-like contact surface 52 g (FIG. 15) on the outer wall of the housing member 52. ) And the rotation is restricted. When the operating portion 54a is released at this position, the operating member 54 is retracted to one end side of the base portion 51a by the spring 55 and is locked to the locking portion 33d formed on the resin frame 33. Thereby, the movable glass 32 is held by the fixed glass 31 without rattling. In addition, a ratchet mechanism may be provided in the accommodating portion 52 so that the movable glass 32 can be stopped at a position desired by the user.

  As shown in FIG. 12, the operation part 54a is pushed in when the movable glass 32 is open. Since the movable glass 32 is located at the outer position, when the operation member 54 is rotated downward, the movable glass 32 is gradually closed. When the movable glass 32 is completely closed, the base portion 51 a comes into contact with the plate-like portion 33 e protruding from the lower portion of the resin frame 33 and stops. At this time, the support shaft 51b of the support member 51 is aligned in the same direction as the storage portion 52a of the storage member 52, so that the support portion 51b can enter the storage portion 52a. As shown in FIG. 7, when the operation part 54 a is released, the operation member 54 is retracted to one end side of the base part 51 a by the urging force of the spring 55. Due to the urging force of the urging member 53, the support portion 51 b enters the housing portion 52 a, the pin 52 d enters the through hole 51 c, the support member 51 approaches the housing member 52, and the support member 51 together with the movable glass 32. It is moved inside the car body. The movable glass 32 returns to the inner position on the same plane as the fixed glass 31.

  In this example, the movable glass 32 is held at an inner position that forms the same surface as the fixed glass 31 when closed. When the movable glass 32 is opened from the closed state, the movable glass 32 is moved to the outer position outside the vehicle body from the inner position, and is movable in the plane direction of the movable glass 32. For this reason, the movable glass 32 can be rotated in the plane direction without entering the inside of the door body 1 to open the window region 3. Therefore, interference with the internal structure of the door body 1 can be prevented.

  Further, regardless of whether or not the internal structure of the door body 1 is provided, it is not necessary to provide a space for the movable glass 32 to descend inside the door body 1, leading to saving of the internal space. In addition, the degree of freedom in designing doors will increase, leading to the creation of innovative designs.

  Further, only a part of the window region 3 is covered with the movable glass 32. The movable glass 32 is a lightweight resin glass. For this reason, compared with the case where the whole window area | region is made into a movable glass, the weight of the movable glass 32 can be made comparatively light, and the load added to the opening-and-closing mechanism 5 at the time of movable glass movement can also be made small. Therefore, the movable glass 32 can be easily moved.

  Further, since the opening / closing mechanism 5 includes the support member 51, the housing member 52, the biasing member 53, and the operation member 54, the movable glass 32 can be opened and closed with a simple configuration, and the manufacturing cost is low. can do. In addition, the size of the opening / closing mechanism 5 can be reduced, leading to a reduction in weight.

  A protrusion 34 made of an elastic member is formed on a portion of the edge of the movable glass 32 that engages with the edge of the fixed glass 31. A resin frame 33 is provided at the edge of the fixed glass 31. For this reason, the protrusion 34 elastically contacts the fixed glass 31 when the movable glass 32 is closed. For this reason, a gap is hardly generated between the movable glass 32 and the fixed glass 31. Moreover, the play of the movable glass 32 can be suppressed.

  Further, since the fixed glass 31 and the movable glass 32 are both made of resin, and the door body 1 is also made of resin, it is lightweight and has a high heat insulating effect. Further, when the door body 1 is made of metal, a welding error occurs. However, since the door body of the present embodiment is resinous, the dimensional stability is good.

  In the present embodiment, the movable glass 32 covers the opening 31a in the fixed glass 31, but between the fixed glass 31 and the door body 1, or between the fixed glass 31, the door body 1, and the window frame 2. You may coat | cover the area | region between.

  Moreover, in this embodiment, although the window frame 2 is being fixed to the door main body 1, the case where there is no window frame 2 may be sufficient.
