Description

The present invention relates to a door mounting method and a door mounting structure for a vehicle such as an automobile.

Conventionally, as shown in FIG. 8, each of a pair of left and right back doors 2 (generally referred to as "gateways") provided on a cargo bed 11 at the rear of a truck Ve is horizontally rotatable using a hinge member 4. I have something set up. According to such a configuration, it is possible to rotate the back door 2 when loading and unloading cargo onto and from the loading platform 11 .

However, the prior art described above has room for improvement as follows.

That is, the back door 2 of the truck vehicle Ve described above may be temporarily removed from the hinge member 4 of the loading platform 11 and then reattached to the hinge member 4 thereafter.
To give a specific example, in the manufacturing process of the truck vehicle Ve, when the assembly of the vehicle body 1 is completed, the vehicle body 1 is usually subjected to electrodeposition coating. However, when the height dimension of the back door 2 is large, the vehicle body 1 tends to float when the vehicle body 1 is immersed in the electrodeposition liquid. For this reason, it is conceivable that the back door 2 is removed from the loading platform and then subjected to electrodeposition coating. In this case, after completion of the electrodeposition coating, the back door 2 is attached to the hinge member 4 of the loading platform 11 again.

Here, when reattaching the back door 2 to the hinge member 4 of the loading platform 11, it is necessary to adjust the back door 2 to an appropriate position and posture. However, one end of the back door 2 is bolted to the hinge member 4 in a cantilevered manner, and the plurality of holes provided in the hinge member 4 for bolt insertion are provided to the hinge member 4. It is formed in a size with appropriate play with respect to the shank of the bolt used for attachment. Therefore, the back door 2 may tilt in a direction in which the side opposite to the hinge member 4 (the other end side) descends due to the rotational moment caused by its own weight.

Conventionally, the back door 2 must be installed so as to eliminate the inclination of the back door 2, but this work is not easy, and skill is required to increase the installation accuracy of the back door 2. It takes a long time to work on it. Therefore, it is desired that such problems be appropriately resolved.
Conventionally, a dedicated bolt (centering bolt) is also used to position the back door 2, but this necessitates high precision bolt insertion holes on the hinge member 4 side and a dedicated bolt. Since it is necessary to use bolts, the cost is increased and the assembling property is deteriorated.

When it becomes necessary to install the door, it is possible to improve the installation accuracy of the door while facilitating the installation work.
More specifically, when the door is reattached to the hinge member, one of the plurality of fastening members presses against the inner peripheral surface of the corresponding hole of the hinge member due to the rotational moment due to the door's own weight. Even if the phenomenon occurs, the door and the hinge member can be fastened again by the plurality of fastening members while maintaining the positional relationship between the plurality of fastening members and the plurality of holes of the hinge member. In the present invention, the inclination of the door is reduced on the premise that the door is inclined by its own weight, so that the door does not assume an unreasonably large inclination due to its own weight. Therefore, unlike the prior art, it is possible to improve the installation accuracy of the door while facilitating the reattachment work of the door.

A vehicle door mounting structure provided by a second aspect of the present invention is a hinge for supporting rotation of a door, which is mounted on a target portion of a vehicle for door mounting and is set in a state in which a portion of the vehicle door is overlapped. and a plurality of fastening members that are fixed to the door while being inserted into a plurality of fastening member insertion holes provided in the hinge member, and that fasten the door and the hinge member. , wherein the door and the hinge member are arranged so that at least one of the plurality of fastening members corresponds to the fastening member by tilting the door due to its own weight. At least one of the hinge member and the door mounting target portion is deformed or displaced so as to be arranged in pressure contact with the inner peripheral surface of the hole and fastened by the plurality of fastening members so that the inclination of the door is reduced. It is characterized by further comprising a built-in adjustment part in which

According to such a configuration, the same effect as described in the vehicle door mounting method provided by the first aspect of the present invention can be obtained, and after the door is removed from the hinge member, the When the door is to be reinstalled, it is possible to improve the installation accuracy of the door while facilitating the installation work.
In addition, there is no need to use special bolts (centering bolts) or to make the hole for inserting the fastening member on the side of the hinge member highly accurate. Furthermore, the assembling work is also facilitated.

Preferred embodiments of the present invention will be specifically described below with reference to the drawings.
For ease of understanding, elements identical or similar to those of the prior art shown in FIG.

A vehicle V shown in FIGS. 1 and 2 is a truck vehicle having a structure in which a loading platform 11 is provided on the rear side of a cabin portion 10 as a vehicle body 1, and its basic configuration is the conventional vehicle shown in FIG. Similar to Ve. However, the vehicle V of the present embodiment has a vehicle door attachment structure A to which the present invention is applied at the rear portion of the loading platform 11 .

A vehicle door mounting structure A includes a pair of left and right back doors 2 called a "gate", a pair of left and right hinge members 4 to which the pair of back doors 2 are attached using a plurality of bolts 3, and a pair of back doors 2. It is provided with a fitting adjustment part 5 in which fitting adjustment has been made.
The back door 2 corresponds to an example of the "door" of the vehicle according to the present invention, and the bolt 3 corresponds to an example of the "fastening member" according to the present invention.

A loading platform 11 of the vehicle V includes a floor portion 11a and a pair of side plate portions 11b positioned on both left and right sides of the floor portion 11a and standing upright in the vertical direction. The pair of back doors 2 is a member for opening and closing the rear opening of the loading platform 11, that is, the area between the rear portions of the pair of side plate portions 11b, and has, for example, a substantially rectangular plate shape when viewed from the front. By being attached to each hinge member 4, each back door 2 is horizontally rotatable about a shaft 41 (see FIG. 3) of the hinge member 4, as indicated by an arrow Na in FIG.
The pair of back doors 2 are appropriately provided with an operating lever 28 to be gripped when opening and closing the doors, and a locking lever 29 for locking the closed state when the doors are set to the closed state. there is 2 and subsequent drawings, the levers 28 and 29 are omitted, and the back door 2 is appropriately simplified.
The rear portion of the side plate portion 11b is a portion to which the back door 2 is attached via the hinge member 4, and corresponds to an example of the "vehicle door attachment target portion" in the present invention.

Each hinge member 4 includes a pair of upper and lower fixing pieces 40 fixed to the rear end of the side plate portion 11b of the loading platform 11, and a shaft 41 ( a rotation center pin), and a pair of upper and lower movable pieces 42 having one end fitted onto the shaft 41 and horizontally rotatable about the shaft 41 (see FIGS. 2 to 5). As a result, each hinge member 4 has a movable piece 42 on each of its upper and lower portions, and by attaching the back door 2 to these two movable pieces 42, the back door 2 can be rotatably supported. configuration. It is also possible to divide the hinge member 4 into upper and lower parts (a configuration in which the shaft 41 is divided into an upper shaft and a lower shaft).

A movable piece 42 of the hinge member 4 is provided with a plurality of holes 43 (corresponding to an example of a fastening member insertion hole according to the present invention) for bolt insertion.
These plurality of holes 43 include a reference hole 43a, a secondary reference hole 43b, and a non-reference hole 43c, as shown in enlarged views 1 and 2 of FIG. The reference hole portion 43 a is a round hole with a small amount of play in relation to the shaft diameter of the bolt 3 . The secondary reference hole portion 43b is an elongated hole having a small allowance in the left-right width direction and a large allowance in the vertical height direction. The non-reference hole portion 43c is a so-called blank hole in which the allowance is large in both the horizontal width direction and the vertical height direction.

A plurality of bolt-fixing holes 22 for attaching the back door 2 to the hinge member 4 using the bolts 3 are provided in a region 2 a near one end in the left-right width direction of the back door 2 . In this embodiment, the plurality of bolting holes 22 are, as shown in FIG. into which the bolts 3 can be fitted (screwed) with substantially no play.

The fitting adjustment unit 5 deforms the hinge member 4 or the vicinity of the mounting location of the hinge member 4 at the rear of the side plate portion 11b so that the back door 2 does not tilt or tilts less due to its own weight. Or it is a displaced part. Details thereof will be described later.

Next, a door mounting method for obtaining the vehicle door mounting structure A described above will be described.

First, as shown in FIG. 5, the back door 2 is attached to each of the hinge members 4 in a state in which the pair of left and right hinge members 4 are attached to the pair of side plate portions 11b. For this attachment, as shown in FIG. 6, the region 2a near one end of the back door 2 is superimposed on the movable piece 42 of the hinge member 4, and then the plurality of bolts 3 are attached to the plurality of holes of the movable piece 42. 43 and the bolt hole portion 22 of the back door 2, and screwed into the screw hole portion of the nut 23. As shown in FIG. However, the bolt 3 is not suddenly tightened firmly, but the bolt 3 is loosened and the back door 2 is temporarily fixed to the hinge member 4 in a temporary fixing step.

Here, when setting the temporary fixing state, the back door 2 is tilted by its own weight. Since the center of gravity CG of the back door 2 is located away from the hinge member 4 , a rotational moment M is generated in the back door 2 to lower the center of gravity CG of the back door 2 . The area on the opposite side slopes downward. Due to such an inclination, the gap 8 formed between the pair of left and right back doors 2 is unsightly in that the width Lb on the lower side is larger than the width La on the upper side.

As the back door 2 is tilted as described above, the plurality of bolts 3 are displaced and displaced from the respective centers of the plurality of holes 43 . To give a specific example, the plurality of bolts 3 are displaced, for example, in the directions indicated by the arrows in enlarged views 1 and 2 of FIG. A state (fastening member pressure contact state) is brought into pressure contact with a part of the inner peripheral surfaces of the reference hole portion 43a and the secondary reference hole portion 43b. After creating such a state, the step of sufficiently tightening the bolts 3, that is, the final fastening step of the back door 2 and the hinge member 4 is performed.

After the final fastening process, a construction for reducing the inclination of the back door 2 is performed so that the upper and lower widths La and Lb of the gap 8 formed between the pair of back doors 2 are substantially the same. Carry out the adjustment process (see FIG. 7). In this installation adjustment step, the vicinity of the rear portion of the hinge member 4 and the side plate portion 11b is strongly pressed to deform or displace those portions so as to raise the other end side region of the back door 2. As shown in FIG. The fitting adjustment portion 5 is a portion that has changed its position or shape from its original position or shape as a result of the execution of such a process. For example, in FIG. 3, the center line CL of the shaft 41 is slightly inclined with respect to the vertical direction. On the other hand, as shown in FIGS. 5 and 6, the center line CL of the shaft 41 originally had a non-inclined shape extending vertically. The center line CL of the shaft body 41 is tilted by executing the installation adjustment process, and the portion subjected to such deformation or displacement is the installation adjustment portion 5 .
The door mounting structure A shown in FIGS. 1 and 3 is obtained by completing the fitting adjustment process described above.

In the vehicle V described above, after the vehicle body 1 has been assembled to a certain extent, the body 1 is subjected to electrodeposition coating. It becomes easy to float. Therefore, the electrodeposition coating is applied while the back door 2 is temporarily removed, and then the back door 2 is attached to the hinge member 4 again.
Here, even when the back door 2 is attached again, the back door 2 is subject to a tilting force due to its own weight, and the plurality of bolts 3 are pushed into the inner peripheral surfaces of the plurality of holes 43 of the hinge member 4. Although the phenomenon of pressure contact occurs, the plurality of bolts 3 can be inserted through the plurality of holes 43 and the bolting holes 22 as they are without changing the relative positional relationship between the plurality of bolts 3 and the plurality of holes 43. Then, bolt fastening (refastening) between the back door 2 and the hinge member 4 can be achieved. The vehicle door mounting structure A is based on the premise that the back door 2 tilts due to its own weight, and is designed so that the tilt of the back door 2 is reduced. The door 2 does not assume an unreasonably large inclination due to its own weight. It is possible to improve the installation accuracy of the back door 2 while facilitating the work of attaching the back door 2 again. There is no need to use special bolts (centering bolts), and assembly workability is improved.

The removal of the back door 2 from the hinge member 4 and the subsequent re-attachment are not limited to the electrodeposition coating of the vehicle body 1. It is carried out for reasons other than electrodeposition coating, such as installation of equipment. Even in such a case, as described above, it is possible to improve the installation accuracy while facilitating the reattachment work of the back door 2. , removal of the back door 2 and subsequent re-installation.

The invention is not limited to the content of the embodiments described above. The specific configuration of each step of the vehicle door mounting method according to the present invention can be changed in various ways within the intended scope of the present invention. Further, the specific configuration of each part of the vehicle door mounting structure according to the present invention can be modified in various ways within the intended scope of the present invention.

The door referred to in the present invention is not limited to a back door as a "gateway" provided at the rear of a truck vehicle. The present invention can be applied to various doors as long as they are rotatably supported using hinge members. Therefore, back doors other than "gateways" and side doors provided on the side of a vehicle are also included in the doors of the present invention. Therefore, the door attachment target site is not limited either.
The hinge member in the present invention is not limited to a hinge in a narrow sense, but means a member capable of rotatably supporting a desired member, and its specific configuration is not limited.
The fastening members in the present invention are not limited to bolts, and other fastening members can be used, and the specific number of fastening members and holes for inserting fastening members is not limited.
