Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to an improvement of an automobile side door hinge that utilizes a four-bar rotation link mechanism.

[Conventional technology]

Conventionally, side doors in automobiles, such as passenger cars, have been installed so that they rotate and open/close around a single hinge fixed to the body in most cases. In order to do this, the door opening angle must match the total length of the side door. At this time, if the space on the side of the car is narrow, the door cannot be opened sufficiently, making it difficult for passengers to get in and out of the vehicle. There are many. On the other hand, as disclosed in, for example, Japanese Utility Model Application Publication No. 57-46014 or No. 55-101263, two points separated from each other on the body side of the automobile and two points separated from each other on the side door side of the automobile are disclosed. Among the points, a rotation link that connects one point of each of the body and the side door as the rotation center, a rotation link that connects the other one point as the rotation center, and a portion between the two rotation centers on the body side. An automobile side door hinge has been proposed in which a four-bar rotation link is formed by a portion between two rotation centers of the side door. Side door hinges that use this kind of four-section rotating link secure space for the occupants' feet, while
The required space on the side of the vehicle can be reduced, and therefore, even if the space on the side of the vehicle is narrow, passengers can get in and out by opening and closing the side door. In a side door hinge using a four-bar rotation link as described above, the rotation center axis on the side door side is separated from the rotation center axis on the body side by the length of the rotation link, so the side door hinge is separated from the rotation center axis on the body side by the length of the rotation link. The moment based on the load increases, and this moment also applies a large load to the mounting portion of the rotating shaft on the side door side. Therefore, in order to increase the support rigidity of the side door, it is necessary to arrange multiple door hinges in the vertical direction.
must be installed. However, when multiple side door hinges are installed vertically in this way, their rotational axes must be aligned vertically,
There is a problem that the installation work and adjustment are complicated. Furthermore, the mounting surfaces of the rotation center shaft on the body side and the side door side, especially the mounting surface on the side door side, must have considerably high rigidity, and in order to satisfy this requirement, the weight of the side door Another problem arises in that the weight of the door hinge must be increased. That is, if the rigidity of the side door is small, combined with the long length of the door hinge, that is, the rotation link,
For example, when the side door is opened, the vertical stiffness, torsional stiffness, and over-opening stiffness of the side door are reduced.
There is a problem in that the side door is displaced downward, twisted, or deformed when fully opened. Furthermore, even when the door is closed, if the rigidity is small,
There is a problem in that it is difficult to attach it to the body. In contrast, the present applicant has proposed a door side base that is formed long in the vertical direction along the swing base end of the side door and that is attached to the end. a body side base that is formed vertically long along the body side surface adjacent to the end portion and is attached to the surface; and at least two locations each on the upper and lower portions of the door side base and the body side base. four upper rotational center shafts supported by the upper rotational center shafts, four lower rotational center shafts aligned below the upper rotational center shafts, and each of the body side base and the door side base among the upper rotational center shafts. An upper first arm whose both ends are rotatably connected to one rotational center axis; and a lower part whose both ends are rotatably connected to the lower rotational center axis which is aligned with the upper rotational center axis at both ends of the upper first arm. It has a first arm, an upper second arm whose both ends are rotatably connected to the other upper rotational center axis, and a lower second arm whose both ends are rotatably connected to the other lower rotational center axis. We are proposing a side door hinge for automobiles. Here, in the side door hinge as described above, in order to improve the accuracy of the rotation center axes of each arm constituting the four-section rotation link, these rotation center axes are set on a vertically long plate-shaped body side base and It is supported by a door side base, and the body side base and door side base are fastened and fixed to the body side and side door side with bolts. If the body side base and door side base, which are such large components, are tightly tightened and fixed on the entire surface facing the body and side door, it is possible to pass the car through the painting process with the side door hinge pre-assembled. In this case, not only is there a fairly large area where paint does not adhere between the body side base and door side base and the body and side door, but also the body side base and door side base are in close contact with each other in the paint drying oven. Therefore, there is a problem in that the temperature of the body and side door at the contact surface is prevented from increasing, and some areas may be insufficiently dried.

[Problem that the invention attempts to solve]

This idea was made in view of the above-mentioned conventional problems, and it minimizes the area that does not get painted during the painting process, and also does not prevent the temperature rise of the body and side door in the paint drying oven. The purpose of the present invention is to provide a side door hinge for an automobile.

[Means to solve the problem]

This invention consists of a door side base that is formed long in the vertical direction along the swing base end of the side door and is attached to the end, and a door side base that extends along the body side surface adjacent to the end. a body side base which is elongated in the vertical direction and is attached to the surface thereof; and four upper rotation center shafts supported at at least two positions each at the upper and lower parts of the door side base and the body side base, and the upper part. Of the four lower rotation center shafts aligned below the rotation center shaft and the upper rotation center shaft, both ends are rotatably connected to one rotation center shaft of each of the body side base and the door side base. an upper first arm, a lower first arm whose both ends are rotatably connected to the lower rotational center axis aligned with the upper rotational center axis at both ends of the upper first arm; A side door hinge for an automobile comprising: an upper second arm rotatably connected; and a lower second arm having both ends rotatably connected to the other lower rotation central axis, the door side base and By making the surface of the body side base facing the side door and the body side surface, other than the mounting surface to the side door and the body side surface, a floating surface that does not come into contact with the side door and the body side surface. It accomplishes its purpose. Further, the present invention achieves the above object by making the mounting surface a portion near the periphery of a bolt through hole for fastening the door side base and body side base to the side door and body side surfaces.

[Effect]

In this invention, by floating the parts of the door side base and body side base other than the mounting surface on the side door and body side, it is possible to avoid contact with the mounting surface on the side door side and the surface on the body side when installed. As a floating surface, the paint wraps around the floating surface portion during the painting process, and in the paint drying oven, the temperature rise of the body and side door at the floating surface portion is not hindered. be.

Corresponding to these stoppers 52A, 52B, a side door 1 is provided on the side of the body side base 20.
The protrusion 5 is formed with stopper surfaces 54A and 54B that the stoppers 52A and 52B come into contact with to regulate the fully open position of the side door 12 when the side door 12 is in the fully open position.
6A and 56B are provided. These protrusions 56A and 56B protrude at the corner between the lower surface of the bearing support section 21A and the inner surface of the body side base 20, and at the corner between the upper surface of the bearing support section 21B and the inner surface of the body side base 20, respectively. It is formed. Furthermore, the pipe portion 3 in the main arm 32
3, a door check mechanism 60 is constructed between a torsion bar hook 58, which is formed to protrude horizontally at approximately the vertical center position, and the bearing support portion 21A of the body side base 20. This door check mechanism 60 is composed of a torsion bar 62, a roller 64, and a cam plate 66. As shown in FIG. 1, the torsion bar 62 has a substantially U-shaped curling portion at its lower end, the tip of which is bent at a right angle.
The torsion bar hook 58 of the pipe portion 33 is inserted between the two axes of the bottom side of the letter and the right-angled bent portion from above and below, thereby positioning the pipe portion 33 in the axial direction. Further, the torsion bar hook 58 is inserted from the left and right sides by the U-shaped two shaft portions to position the torsion bar hook 58 in the rotational direction. The upper end of the torsion bar 62 has a crank shape, and the roller 64 is fitted from the upper end so as to be rotatable and swingable in the axial direction. Reference numeral 58A in FIG. 4 indicates the torsion bar hook 5.
Recesses 68A and 68B for positioning the rotational direction of the torsion bar 62 formed at 8 are formed in the upper arm 38A of the main arm 32, and represent positioning protrusions that sandwich the torsion bar 32, respectively. The cam plate 66 is connected to the bearing support portion 2
It is a flat plate-shaped member attached to a portion of the upper surface of the door side base 16 facing the door side base 16, and its cam surface 66A is parallel to the central axis of the pipe portion 33. Further, the cam surface 66A has a lift from the central axis of the pipe portion 33 that is changed at an appropriate position to create a sense of moderation when the side door 12 is opened and closed. A door wire harness 70 for an electric window regulator (not shown) or the like in the side door 12 is located at a position offset downward from a harness hole 72 formed on the front pillar 18 side. The wires are wired in a substantially S-shape while reaching a harness hole 74 formed in the end panel 14 of the side door 12 . Here, the wire harness 70 is attached to the side door 12 of the pipe section 33 in the main arm 32.
Also along the sides, upper and lower control arms 30A, 30B in the main arm 32.
It is arranged to pass through the V-shaped part between the two. The wire harness 70 is fixed to a harness clamp bracket 78 protruding from the body side base 20 via a harness clamp 76 at a position near the pipe portion 33 . The harness clamp 76 is made of resin, and holds the wire harness 70 at its annular portion 76A, and its distal end portion 76B is inserted and fixed into a mounting hole 78A formed at the distal end position of the harness clamp bracket 78. There is. Furthermore, the pipe portion 3 in the main arm 32
3, the position adjacent to the wire harness 70, that is,
A resin harness protector 80 is attached to the vertical gap between the upper arm 38A and the lower arm 38B at the connection to the pipe section 33, so that the wire harness 70 comes into contact with the pipe section 33. This is to prevent the paint from peeling off from the pipe portion 33. As shown in FIG. 4, the harness protector 80 has a slit 80C extending vertically.
It is a substantially cylindrical member that can be expanded by means of a cylindrical member, and has one notch 80A and one notch 80B formed at each of its upper and lower ends. On the other hand, on the pipe portion 33 side, projections 82A, 82B, and 82C are formed at positions corresponding to the notches 80A and 80B of the harness protector 80 and at positions corresponding to the slits 80C. When elastically fitted into the projections 82A to 82C, the notches 80A, 80B and the slit 80C engage with the protrusions 82A to 82C.
The harness protector 80 is positioned. Here, as shown in FIG. 3, the front end corner of the inner panel 12A of the side door 12 on the vehicle interior side is located on the inside of the end panel 14 in the vehicle width direction, that is, on the inside of the side door hinge 10 in the vehicle width direction. The door side base 16 is protruded forward from the rear end surface of the door side base 16 on the vehicle interior 84 side, and
A substantially L-shaped weather strip attachment portion 86 is formed in the protrusion 12D. A door weather strip 88 is attached to this weather strip attaching portion 86. On the other hand, a weather strip contacting surface 18B of the front pillar 18 corresponding to the door weather strip 88 is formed offset from the surface 18A toward the passenger compartment 84, so that when the side door 12 is fully closed, the weather strip contact surface 18B is formed offset from the surface 18A toward the passenger compartment 84. The contact surface 18B is adapted to come into contact with the surface of the weather strip 88 on the vehicle interior 84 side. In this case, the corner of the weather strip contact surface 18B, that is, the front-rear direction position of the rear end surface 18C of the front pillar 18 is
Corresponding to the longitudinal position of 6, it is offset forward compared to the normal case. Next, the operation of the above embodiment will be explained. When the side door 12 is opened from the fully closed state, the main arm 32 swings counterclockwise in FIG. 3 about the upper rotation center axis 28A and the lower rotation center axis 28B, and the upper control arm 30A Centered around the rotation center axis 26A,
Further, the lower control arms 30B each swing counterclockwise in FIG. 3 about the lower rotation center shaft 26B. Since the main arm 32 and the upper and lower control arms 30A and 30B constitute a four-section rotating link, the instantaneous rotation center of the side door 12 changes gradually, and the side door 12 is slid forward while opening to the side of the vehicle body. become. At this time, the rear end portion 11A of the front side fender 11 is connected to the extension portion 12 of the side door 12.
Corresponding to the front end of C, the upper control arm 30A and the lower control arm 30B are located in a forward position than the upper rotation center axis 26A at the frontmost position, so that the upper control arm 30A and the lower control arm 30B are slightly bent and are almost straight. Also, when the side door 12 is fully opened,
Rear end portion 11A of the front side fender 11
There is no interference with Further, the upper rotation center shafts 22A, 24A, 26
A, 28A and lower rotation center shaft 22A, 22B, 2
4B and 26B are aligned on the inclined axes that intersect at the lower point 10A, so the upper end of the fully opened side door 12 tilts outward, making it easier for passengers to get in and out. When the side door is opened or closed, a roller 64 rotatably attached to the torsion bar 62 of the door check mechanism 60 is brought into rolling contact with the cam surface 66A of the cam plate 66 as the side door 12 swings (see FIG. 13). The torsion bar 62 supporting the roller 64 is
Torsional force is received from the cam surface 66A of the cam plate 66. Since the distance of the cam surface 66A of the cam plate 66 from the upper rotation center axis 28A is changed as appropriate, the torsional force applied to the torsion bar 62 changes as the lift amount (lift height) of the cam surface 66A changes. Ru. Therefore, a sense of moderation is created when opening and closing the side door 12. When the side door 12 is in the fully open position, the stoppers 52A and 52B protruding from the pipe portion 33 of the main arm 32 close the body side base 20.
The protrusions 56A, 56B are brought into contact with the stopper surfaces 54A, 54B, thereby regulating the fully open position. Opposing surfaces 90 and 92 facing the end panel 14 and front pillar 18 of the door side base 16 and body side base 20, respectively.
are the respective bolt holes 16A, 16B and 20
Only the surroundings of A, 20B, and 20C are the mounting surfaces 90A, 92A that contact the end panel 14 or the surface 18A of the front pillar 18, and the other parts are the non-contact floating surfaces 90B, 92B. Side door 1 by side door hinge 10
When the automobile is put into the painting process with the parts 2 attached, paint tends to enter between the end panel 14 surface of the side door 12 and the surface 18A of the front pillar 18, and the door side base 16 and body side base 20. Furthermore, even when heated in a paint drying oven, since the contact surfaces between the door side base 16 and body side base 20 and the end panel 14 and front pillar 18 are small, these end panels 14 and the front pillar 18 are
There is little hindrance to the temperature rise of 8A, and therefore insufficient drying is suppressed. Further, the bolt holes 16A, 16B and 20A, 20B in the door side base 16 and the body side base 20 are formed at the upper and lower ends of each,
In addition, bearing support portions 17A, 17B and 21A, 2 for supporting the rotation center axis of the four-bar rotation link are provided.
1B is the bolt hole 16A, 16B, 20A,
20B, the side door hinge 10 can be formed as long as possible in the vertical direction, increasing rigidity and effectively dispersing the load of the side door 12. Further, since the bolt holes and the bearing support portions are located close to each other, it is possible to prevent excessive concentrated loads from being applied to the door side base 16 and the body side base 20. Further, in the above embodiment, stoppers 52A and 52B for regulating the fully open position of the side door 12 are provided.
are formed at the upper and lower ends of the pipe portion 33 of the main arm 32, that is, at positions close to the bolt holes 20A, 20B, and 20C of the body side base 20, so that the stoppers 52A, 52B are formed in the body of the body side base 20. The tendency for the side attachment portion to easily deform is suppressed. Further, a protrusion 56 forming stopper surfaces 54A, 54B that come into contact with the stoppers 52A, 52B.
Since A and 56B are formed on the inner surface of the body side base 20 and the corners of the pair of upper and lower bearing supports 21A and 21B, they reliably absorb the impact force generated by contact with the stoppers 52A and 52B. be able to. In the above embodiment, the main arm 32, which is vertically integrated, has a pipe portion 33 and an upper arm 3.
8A and a lower arm 38B, the present invention is not limited to this, and the main arm 32 may be divided vertically, or In the case of one piece, it is one piece in the vertical direction, and the upper rotation center axis 24A,
28A and the lower rotation center shafts 24B, 28B in a rotatable manner. Therefore, for example, the main arm 32 may have a frame shape by providing a pipe portion that fits into the upper rotation center shaft 24A and the lower rotation center shaft 24B on the side door 12 side. However, when the main arm 32 is formed into a substantially K-shape as in the embodiment shown in FIG. 1, there is an advantage that interference with the wire harness 76 can be avoided and the weight can also be reduced. Further, the upper control arm 30A and the lower control arm 30B may be formed integrally in the vertical direction. In short, the present invention is generally applicable to side door hinges having a pair of vertically similar four-bar rotation links.

[Effect of the idea]

Since the present invention is constructed as described above, in an automobile side door hinge that utilizes a four-bar rotation link that is integrated with a door side base and a body side base and is attached to the side door and body side via these, The paint goes around the mounting surfaces of the door side base and body side base to the side door and body side during the painting process, and the temperature rise of the body side and side door at these mounting surface portions is prevented in the paint drying oven. It has the excellent effect of being able to suppress this.
