DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile door structure having a door sash frame, and more particularly, to an automobile door in which a weatherstrip mounted on the door sash frame does not interfere with a door opening on a vehicle body. Regarding the structure.

[0002]

2. Description of the Related Art Generally, an automobile is provided with doors (front doors, rear doors) 2 and 3 on the side of a vehicle body 1 as shown in FIGS. As shown in FIG. 1, there is a door structure in which door sash frames 4 and 5 are provided on the upper portions of door bodies 12 and 13 including an outer panel and an inner panel (not shown).

[0003] Incidentally, most automobile doors of passenger cars and the like are formed, for example, as shown in FIG. Such a shape is intended to reduce the air resistance of the vehicle body against the cross wind, and also leads to an improvement in the appearance of the vehicle body. Although FIG. 6 relates to the rear door, the front door is similarly formed. Also,
In FIG. 6, reference numerals 13A and 13B denote an outer panel and an inner panel constituting the door body 13, respectively.

[0004] When the shape of the door is configured as described above, the door sash frame 5 is more deviated toward the vehicle interior ( toward the center of the vehicle body) with respect to the door main body 3. Thus, the door sash frame 5 in the door closed state is located at the hinge point of the door hinge 6 attached to the door main body 3, that is, on the vehicle interior side (body center side) with respect to the rotation center 7 of the door.

Therefore, the rear portion 15 of the door sash frame 5 erected upward from the rear edge of the door body 3
Along with the rotation of the door 3, the door 3 turns on a rotation locus as shown by a chain line L1 in FIG. In other words, near the door closed state,
A line L2 connecting the center 7 of rotation of the door and the rear portion 15 of the door sash frame 5 is, for example, at an angle with respect to a side surface L3 of the vehicle (in this case, a surface portion of the door outer panel 13A which projects most outwardly). The rotation locus L1 in the vicinity of the door closed state forms an angle α with the vehicle width direction (a line direction orthogonal to the line L3 indicating the side of the vehicle) as indicated by the straight line L4. Become.

FIG. 8 is a cross-sectional view showing the state of the rear portion 15 of the door sash frame 5 in the vicinity of such a closed state of the door. As shown in FIG. 8 and a frame body surface 5A formed so as to cover the outer periphery of the edge portion, and an outer surface 5B formed so as to be exposed from the frame body surface 5A to the outer surface side of the vehicle body.

A door glass 8 is provided on the inner peripheral side of the frame main body surface portion 5A via a weather strip 16, and a weather strip 17 is provided on the outer periphery of the frame main body surface portion 5A in the vehicle interior. Is mounted while being locked by the claw portions 5D, 5E of the first and second members. The weather strip 17 has a hollow lip portion 19 that can be in close contact with a sealing surface portion (inside portion) 25 formed inside the door opening edge portion 21 on the vehicle body 1 side, and a vehicle outside portion 26 of the door opening edge portion 21. And a lip portion 18 which can be slidably contacted.

Reference numeral 22 denotes an outer panel of the vehicle body that forms the door opening edge 21, and reference numeral 23 denotes an inner panel that forms the interior side of the vehicle body.
2. The weather strip 20 is mounted on the flange-like connecting portion 24 of the inner panel 23. The weatherstrip 20 is provided with a hollow lip portion 20A that can be in close contact with a sealing surface portion 5C provided on the frame main body surface portion 5A of the door sash frame 5.

When the door is closed, the hollow lip 19 of the weatherstrip 17 is in close contact with the sealing surface (inside of the vehicle) 25 of the door opening edge 21, and the hollow lip 20A of the weatherstrip 20 is closed by the door. By tightly contacting the sealing surface portion 5C of the sash frame 5, the space between the door opening edge 21 and the door 3 is sealed, and the lip portion 18 of the weather strip 17 is attached to the vehicle outside portion 26 of the door opening edge 21. Lip section 18 that can adhere
The lip portion 18 is provided on the outer side portion 26 of the vehicle.
The sliding contact prevents dust and dirt from entering the vehicle.

In particular, the hollow lip 19 of the weather strip 17 not only serves as a main body of the door seal, but also cushions the impact on the door opening edge 21 of the door body 3 and the door sash frame 5 when the door is closed. It is also important for improving the sound and tactile sensation when closing the door. In recent years, due to the addition of reinforcing structures inside doors and the increase in door fittings, etc.,
Since the weight of the door tends to increase, the hollow lip portion 19 of the weather strip 17 is required to be increased in size for the purpose of door sealing and buffering when the door is closed. Needless to say, the size of the hollow lip portion 19 is increased, and the sealing surface portion (the inner side portion) 25 of the door opening edge portion 21 is formed.
Is also enlarged at the same time.

Further, when the door is turned, an end portion (a portion turning outermost at the time of turning) 19A of the hollow lip portion 19A of the weather strip 17 draws a rotation locus as shown by a curve L1 in FIG. . The rotation trajectory L1 is similar to the trajectory L1 shown in FIG.

[0012]

Incidentally, the weather strip 17 is not closed when the door is opened and closed due to variations in adjustment of the door to the vehicle body.
In some cases, the single lip 19a of the hollow lip 19 of FIG. 7 hits the edge of the door opening, for example, causing rotation around the point A in FIG. That is, when the door is closed, the weather strip 17 enters the vehicle body 1 while rotating clockwise around the point A and closely adheres to the seal surface portion 25. When the door is opened, the weather strip 17 is counterclockwise around the point A. It moves away from the vehicle body 1 while rotating in the direction. FIG. 8 shows the case of the left door. On the contrary, in the case of the right door, rotation may occur counterclockwise when the door is closed and clockwise when the door is opened.

As described above, the weather strip 17 is
Since the swing operation may be repeated by the opening and closing operation of the door, not only the durability of the weather strip 17 is lowered but also the slight interference (contact) between the weather strip 17 and the door opening edge 21 may cause the weather strip 17 to be closed. There is also a problem that the strip 17 comes off the door sash frame 5.

Of course, such a situation can be avoided if the weather strip 17 can be prevented from contacting the door opening edge 21, but at present, the contact between the weather strip 17 and the door opening edge 21 is ensured. It is difficult to avoid. That is, as described above, when the size of the hollow lip portion 19 of the weather strip 17 is increased,
Since the turning radius of the rotation locus L1 of the end portion 19A of the hollow lip portion 19 is enlarged, the door sash frame 5
(See the position indicated by reference numeral 55 in FIG. 8)
As shown by reference numerals 119 and 119A in FIG. 8, the hollow lip portion 19 and its end edge portion 19A move, and the rotation trajectory L1 approaches the vehicle outside portion 26 of the door opening edge portion 21.

When the door 3 rotates from the closed state, the rotation trajectory L1 of the edge 19A forms a direction that forms an angle of α with the vehicle width direction L4, as shown in FIG. Therefore, the gap D1 between the edge portion 19A and the vehicle exterior portion 26 is gradually reduced, and the rotation locus L1 also approaches the vehicle exterior portion 26 at this point. As described above, when the rotation trajectory L1 approaches the vehicle exterior portion 26, the edge 19A comes into contact with the vehicle exterior portion 26 of the door opening edge 21 even with a very slight manufacturing error (production variation) ( The reference numerals 219 and 219A in FIG. 8) cause the weather strip 17 to come off.

Therefore, the rotation locus L1 and the door opening edge 21
Want to make the gap D1 with the vehicle outside portion 26 larger. In order to make the gap D1 larger, the radius itself of the rotation locus L1 can be reduced, or the angle α between the rotation locus L1 and the vehicle width direction L4 near the closed state of the door 3 can be reduced to open the door. It is conceivable to reduce the degree of approach of the rotation trajectory L1 to the vehicle outside portion 26.

However, since it is desired to increase the size of the hollow lip 19, the radius itself of the rotation locus L1 cannot be reduced. Further, in order to secure a door shape that is strong against side winds, the angle α formed between the rotation trajectory L1 and the vehicle width direction L4 near the closed state of the door 3 cannot be reduced.
Therefore, the gap D1 cannot be increased by these means.

Further, as shown by a chain line in FIG. 8, the gap D1 can be increased by displacing the outside portion 26 of the door opening edge 21 to the rear of the vehicle. If the vehicle is displaced rearward, the gap D2 between the vehicle outer portion 26 and the outer surface 5B of the door sash frame 5 becomes large and the appearance of the vehicle is deteriorated, so that this means is not practical. In this case, the outer side portion 26 of the door sash frame 5 is displaced rearward,
It is conceivable that the rear edge 5F of B is also extended rearward at the same time to prevent the gap D2 from expanding. However, since the shape balance of the door sash frame 5 is deteriorated, this means is not practical.

On the other hand, as shown in FIG. 9, when the frame main body surface portion 5A of the door sash frame 5 is displaced as shown by an arrow A1 to increase the inclination of the frame main body surface portion 5A, the radius of the rotation locus L1 is changed to the frame itself. Body surface 5A
Can move the space S for installing the hollow lip portion on the inner side of the outer vehicle compartment toward the center of rotation of the door, so that the hollow lip portion 19 can be enlarged while the radius itself of the rotation locus L1 is reduced. Frame body surface 5A and outer surface 5
In order to reduce the angle β with B, there is a limit in terms of molding, and there is a limit in securing the rigidity of the door sash frame 5, and there is a slight problem in this respect.

Further, there is a possibility that the weather strip 17 and the door opening edge 21 approach each other as described above.
The location where the door turning center line and the axis of the door sash frame 5 are close to parallel, that is, the location where the axis of the door sash frame 5 stands up like the rear portion 15 in the door sash frame 5. In a portion of the door sash frame 5 where the axis of the door sash frame 5 is inclined (forwardly inclined), such as the upper portion, there is little risk of the weather strip 17 and the door opening edge 21 approaching.

Therefore, by partially reducing the size of the hollow lip portion 19 of the weather strip 17 only in the rear portion 15 of the door sash frame 5, the rotation locus L
It is also conceivable to reduce the radius itself of 1 and increase the gap D1. However, it is difficult to partially reduce the size of the weatherstrip 17 in this way, and it also leads to a decrease in the durability of the weatherstrip 17. Therefore, such a technique is also not a practical means. . Particularly, as in the rear door of a four-door car, the frame axis is formed upward and curved like a rear part 15 of the door sash frame 5 (that is, the front part of the door sash frame 5 is formed on the frame axis). In such a case, the weather strip 17 is not bent.
Partial miniaturization to make it discontinuous is problematic.

The present invention has been made in view of the above-mentioned problems, and satisfies the required shape and size of a door sash frame and a weather strip, while allowing the door strip to rotate between the weather strip and the door opening edge. It is an object of the present invention to provide an automobile door structure capable of reliably avoiding interference.

[0023]

According to a first aspect of the present invention, there is provided a door structure for a vehicle, the front edge of which is rotatably mounted on a vehicle body, and the door body is provided on an upper portion of the door body. The door sash frame is formed so as to cover the outer periphery of the edge portion of the door glass, and the door sash frame is formed so as to be exposed from the frame body surface to the outer surface side of the vehicle body. The door sash frame is configured so that the outer edge of the outer surface and the outer portion of the door opening edge on the vehicle body side have a required interval. In an automobile door structure, which is provided at a position deviated toward the vehicle center from the position of the center of rotation of the door main body in the vehicle width direction, the door sash frame is mounted on the outer side of the frame main body surface of the door sash frame in the vehicle interior. Do A weather strip that can abut on the vehicle interior portion of the opening edge, and separates a rotation trajectory of an outer end portion of the weather strip generated by rotation of the door body from the vehicle exterior portion of the door opening edge; In order to achieve this, a rear portion of the door sash frame, which is erected upward from a rear edge of the door main body , has a surface portion of the frame main body.
The inner end side of the door sash frame is a part other than the rear side part.
It is characterized in that it is formed so as to be displaced toward the side separated from the vehicle outside portion as compared with the inside end side .

According to a second aspect of the present invention, there is provided an automobile door structure according to the first aspect, wherein the door sash frame stands substantially upward from a rear edge of the door main body at a rear portion thereof. Is provided, and is formed so as to gradually incline toward the front of the vehicle body as it goes upward, and a displacement of an inner end side of the frame main body surface portion in a rear portion of the door sash frame is given by torsional deformation, The torsional deformation is processed so that the degree of torsion is reduced as the front side of the door sash frame is inclined forward of the vehicle body.

When the door is a rear door,
In a rear door in which it is difficult to solve the detachment of the weather strip, detachment of the weather strip can be reliably avoided. According to a third aspect of the present invention, there is provided a door structure for an automobile according to the second aspect, wherein the door is a rear door, and a fixed door glass that does not move up and down to the upper rear of the rear door is provided. A rear portion covers the outer periphery of the fixed door glass, and the torsion process is formed on the outer periphery of the fixed door glass.

It is to be noted that the inner side portion of the door opening edge to which the weather strip can abut is separated from the outer side portion of the weather strip by the torsion processing (in general, the front side of the vehicle body). ), That is, it is preferable to displace the outside portion of the vehicle in the same direction as the weather strip (generally, toward the front of the vehicle body). In this case, a sufficient contact area between the weather strip and the inside of the vehicle at the edge of the door opening is ensured, and the sealing performance of the door and the sound and tactile sensation at the time of closing the door can be improved.

[0027]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a door structure for an automobile according to an embodiment of the present invention; FIG. The vehicle door structure according to the present embodiment relates to a rear door 3 of a vehicle, and as shown in FIGS. 2A and 2B,
The rear door 3 as an automobile door includes an outer panel 1.
Door body 13 formed by stacking 3A and inner panel 13B
The door sash frame 5 is provided on the upper part of the door sash.

In particular, in the present embodiment, a partition member 9 is provided upright in a space surrounded by the upper edge of the door body 13 and the door sash frame 5, and an elevating door glass 8A is provided forward of the partition member 9. A fixed door glass 8B that does not move up and down is provided behind the partition member 9. As shown in FIG. 2A, such a rear door 3 is formed to have a cross-sectional shape that is curved toward the center of the vehicle body toward the upper side of the door 3 so as to reduce the air resistance of the vehicle body against crosswind and to reduce the body resistance. The appearance is improved. For this reason, similarly to the above, the door sash frame 5 is more deviated toward the vehicle interior (the center of the vehicle body) with respect to the door body 3 [FIG.
(A), see FIG. 3].

For this reason, as shown in FIG.
Door sash frame 5 standing upward from the rear edge
The rear side portion 15 turns with a rotation locus as shown by a chain line L1 with the rotation of the door 3. That is, in the vicinity of the door closed state, the line L2 connecting the center of rotation of the door (the center of the hinge pin of the door hinge 6) 7 and the rear portion 15 of the door sash frame 5 is the side of the vehicle (here, the door outer panel 13A is the most common). For example, it is inclined by an angle α with respect to a surface portion L3 protruding to the outside of the vehicle. (A line direction orthogonal to L3) and α.

Also, in the present door structure for a vehicle, similarly to the conventional example (see FIG. 8), as shown in FIG. 1, the door sash frame 5 covers the outer periphery of the edge of the door glass 8A, 8B. It comprises a formed frame body surface portion 5A and an outer surface portion 5B formed so as to be exposed from the frame body surface portion 5A to the outer surface side of the vehicle body. Also,
Door glasses 8A and 8B are provided on the inner peripheral side of the frame main body surface portion 5A via a weather strip 16, and a weather strip 17 according to the present invention is provided on the outer side of the frame main body surface portion 5A in the vehicle interior. It is mounted while being locked by the claw portions 5D and 5E of 5A. The weather strip 17 has a hollow lip portion 19 that can be in close contact with a sealing surface portion (inside portion) 25 formed inside the door opening edge portion 21 on the vehicle body 1 side, and a vehicle outside portion 26 of the door opening edge portion 21. And a lip portion 18 which can be slidably contacted.

Reference numeral 22 denotes an outer panel of the vehicle body that forms the door opening edge 21, and 23 denotes an inner panel that forms the interior side of the vehicle body.
2. The weather strip 20 is mounted on the flange-like connecting portion 24 of the inner panel 23. The weatherstrip 20 is provided with a hollow lip portion 20A that can be in close contact with a sealing surface portion 5C provided on the frame main body surface portion 5A of the door sash frame 5.

When the door is closed, the hollow lip portion 19 of the weather strip 17 is in close contact with the sealing surface portion (inside of the vehicle) 25 of the door opening edge 21 and the hollow lip portion 20A of the weather strip 20 is closed by the door. By tightly contacting the sealing surface portion 5C of the sash frame 5, the space between the door opening edge 21 and the door 3 is sealed, and the lip portion 18 of the weather strip 17 is attached to the vehicle outside portion 26 of the door opening edge 21. The sliding contact prevents dust and dirt from entering the vehicle.

In FIG. 1, each weather strip 1
The hollow lips 19 and 20A of the first and second seals 20 and 20A come into close contact with the corresponding sealing surfaces 25 and 5C while being elastically deformed at the positions shown in the figure. For easy understanding of the shape, the hollow lips 19, 20A of these weather strips 17, 20 are shown in a natural state without elastic deformation.

By the way, in this automobile door structure, FIG.
As shown in the figure, the rear portion 15 of the door sash frame 5
However, a twisting process is performed such that the inner end side of the frame main body surface portion 5A (that is, the sealing surface portion 5C side) is slightly turned around the rotation center 5G on the outer surface portion 5B toward the front of the vehicle body. That is, originally, the frame body surface portion 5A and the outer surface portion 5B of the door sash frame 5 are installed as shown by a chain line in FIG.
In the rear side portion 15, the frame main body surface portion 5A and the outer surface portion 5B are both installed (see arrow A2) while being rotated as shown by the solid line in FIG.

The rotational displacement of the door sash frame 5 is given by partially twisting the rear side portion 15. Particularly, in the door sash frame 5, a large rotational displacement (torsion amount) is given to the frame base portion 15 </ b> A of the rear portion 15 near the door body 13, but gradually rotates as the distance from the door body 13 increases. The displacement (torsion) is small.

Further, it is configured such that such a rotational displacement is not applied when reaching a position intersecting with the partition member 9. In other words, the torsion processing is applied to a portion of the door sash frame 5 corresponding to the outer peripheral portion of the fixed door glass 8B. In this manner, the rear portion 15 of the door sash frame 5 is subjected to the torsion processing,
The space S for installing the hollow lip portion on the inner side of the outer periphery of the frame body surface portion 5A rotates toward the center of rotation of the door, that is, the front of the vehicle body, and accordingly, the hollow lip portion 19 also moves toward the front of the vehicle body. It can be rotated and moved.
As a result, the rotation trajectory L1 drawn by the end portion 19A of the hollow lip portion 19 is separated from the vehicle outside portion 26 of the door opening edge portion 21 so as to add L1a in FIG. The locus L1b shown in FIG. 1 is that of a conventional door sash frame shown by a chain line in FIG.

In FIG. 1, the door opening edge 21 shown by a chain line is a conventional one, and the door opening edge 21 of the present vehicle door structure is shown by a solid line. With the movement to the front of the vehicle, the sealing surface (inside portion) 25 of the door opening edge 21 is also displaced slightly forward. The amount of displacement of the seal surface portion (inside portion of the vehicle) 25 depends on the amount of rotational displacement of the hollow lip portion 19, that is, the amount of torsion of the rear portion 15 of the door sash frame 5. The portion 19 can surely be brought into close contact with the sealing surface portion (inside portion of the vehicle) 25 with a sufficient area.

The automobile door structure according to one embodiment of the present invention is configured as described above. When the door is opened and closed, the hollow lip portion 19 is formed as shown by a rotation locus L1a in FIG. Of the door opening edge 21 passes through a position sufficiently separated from the vehicle exterior portion 26. In other words, when the door is slightly opened, the hollow lip portion 19 has an end portion 19A (refer to a reference numeral 119A) at a position indicated by a reference numeral 119 in FIG. However, also at this time, as shown in FIG. 1, the distance between the rotation trajectory L1a of the edge portion 19A and the vehicle outside portion 26 of the door opening edge portion 21 increases from D1 to D1a.

Therefore, even if the swinging operation around the point A generated in the weather strip 17 by the opening and closing operation of the door is affected by the manufacturing error of the door frame or the like,
Interference between the weather strip 17 and the door opening edge 21 is greatly suppressed, and the weather strip 17
Can be reliably prevented from coming off the door sash frame 5.

Further, by twisting the main portion of the door sash frame 5, the edge portion 19A of the hollow lip portion 19 is formed.
Of the rotation trajectory L1 drawn by the vehicle outside portion 2 of the door opening edge portion 21
6, the gap D2 between the vehicle outer portion 26 and the outer surface 5B of the door sash frame 5 hardly expands. Therefore, the appearance of the vehicle can be kept good.

Further, by using such a twisting process, the angle β between the frame main body surface portion 5A and the outer surface portion 5B is formed.
Since the size of the door sash frame 5 (see FIG. 9) is not reduced, there is no problem in forming the door sash frame 5 and there is no problem in securing the rigidity of the door sash frame 5. The torsion processing itself is performed by fixing a main part of the door sash frame 5 formed in a state without torsion and applying a required torsion torque to the end on the rear portion 15 side. , Can be easily performed.

By the way, in the frame base 15A close to the door body 13, since the frame axis stands almost vertically and the door turning center line and the axis of the door sash frame 5 are almost parallel, the weather strip 17 and the door Although there is a high possibility of approach to the opening edge 21, the frame axis is inclined forward as the distance from the door body 13 is increased, so that the door turning center line and the axis of the door sash frame 5 are not parallel to each other. The risk of the weather strip 17 approaching the door opening edge 21 is reduced.

On the other hand, in the present vehicle door structure, the amount of torsion is large at the frame base 15A where the frame axis stands upright near the door body 13 and the frame axis moves away from the door body 13 to correspond to this. The amount of torsion is gradually reduced as tilts. Accordingly, the torsion amount is given to a portion where the weather strip 17 and the door opening edge 21 are more likely to approach, so that the risk of the weather strip 17 and the door opening edge 21 approaching can be efficiently eliminated. There is also an advantage.

When the door sash frame 5 is twisted, the door sash frame 5 is inclined and grips the door glass 8B, so that the door sash frame 5 is interposed between the door sash frame 5 and the door glass 8B. The shape of the weather strip 16 should also be set according to this,
In this embodiment, the twisting process is performed only on the portion of the door sash frame 5 corresponding to the outer peripheral portion of the fixed door glass 8B that does not move up and down, and it is not necessary to consider the elevating property of the glass. By using a weatherstrip 16 similar to that described above, the fixed door glass 8B can be configured to be gripped only by changing the setting of the gripping portion of the fixed door glass that is normally set without adding torsion.

In this embodiment, the torsional deformation causes
In the rear portion of the door sash frame, the inner end side of the frame main body surface portion 5A is displaced forward of the vehicle body from the outer end side, and a space S (see FIG. 9) for installing the hollow lip portion 19 is provided on the door. Although it is moved to the rotation center side (left side in the figure), if the problems in securing the formability and rigidity are solved, as shown in FIG. 9, the frame body surface portion 5A and the outer surface portion 5B are formed. The angle β is configured to be small,
The space S may be moved to the door rotation center side. That is, as shown in FIG. 9, only the frame main body surface portion 5A or only the inner end side of the frame main body surface portion 5A is
A structure in which the space S is displaced or rotated in such a direction as to move to the door rotation center side is also included in the structure of the present invention.

Although the present embodiment relates to a rear door, the present vehicle door structure may be applied to an automobile door or a front door having one door on one side.

[0047]

As described above in detail, according to the automobile door structure of the present invention, the outer end rotation trajectory of the weather strip is separated from the outer portion of the door opening edge of the vehicle body. As a result, while meeting the required shape and size of the door sash frame and weather strip, the weather strip can be reliably prevented from interfering with the edge of the vehicle-side door opening, and the door opening / closing operation can be performed. Therefore, even if the weather strip is swung, the weather strip can be prevented from coming off the door sash frame. In particular, without increasing the gap between the outer surface of the door sash frame and the vehicle body when the door is closed, ensuring a sufficient weatherstrip seal, and ensuring the rigidity and manufacturing of the door sash frame. There is an advantage that such detachment of the weather strip can be avoided while ensuring the property.

According to the second aspect of the present invention, there is an advantage that the weather strip can be more efficiently prevented from coming off. According to the third and fourth aspects of the present invention, the torsion process of the door sash frame is provided only in the portion that holds the fixed door glass, so that the door glass can be lifted and lowered. The twisted portion can be formed on the door sash frame without hindrance.
