Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a door for an automobile, and more particularly to a door constructed so that assembly can be performed extremely easily. [Prior art and its problems]

Automobile doors are constructed by incorporating door internal components such as a window regulator, door glass, and door check into a bag-shaped door body that includes an outer panel and an inner panel. . Further, the outer panel and the inch panel are joined to each other by hemming on three sides excluding the belt line portion in order to maintain the appearance of the outer panel. By the way, since the formation of the door body, especially the hemming process for joining the outer panel and the inner panel, is usually performed by press working, the attachment of the door internal components can only be performed after the door body is manufactured. ,For this reason, conventionally, the work of installing internal door components was
This work has to be done in a blind manner, in which the door internal components are inserted into the bag-shaped space inside the door body through a work hole provided in the inner panel, and then screwed into a predetermined part on the back of the inner panel. Therefore, the workability of attaching the internal components of the door is very poor, and as a result, the manufacturing work of the door becomes complicated and troublesome. Furthermore, the fact that the working hole cannot be made too large in order to avoid a decrease in the rigidity of the door is also one of the reasons why the installation work becomes difficult. As a way to temporarily solve this problem, the
No. 5-85922 discloses that the inner plate is cut out at least in its center and upper part, and a door trim that is temporarily attached from the inside of the vehicle to cover the cutout part includes a door glass, a window regulator, etc. An automobile door has been proposed in which internal components of the door are pre-attached. In this automobile door, the door internal components are attached to the door trim, and the door trim is screwed to the inner plate, so that the door internal components can be assembled into the door body. The purpose of this is to improve work efficiency. However, in the case of the automobile door disclosed in the above publication, when attaching the door trim to the inner plate, the door glass or window regulator attached to the door trim must be inserted into the interior while fitting the rear edge of the door glass into the window frame. It is difficult to say that the workability of assembly has been sufficiently improved because it requires the laborious work of inserting reinforcing members between the reinforcing members provided to reinforce the panels and the outer panel. Since it is necessary to secure a mounting allowance for the inner plate at the peripheral edge, there is also a problem in that the mounting position of the door components and the size of the door glass are restricted. The present invention has been devised under the above-mentioned circumstances, and it is possible to improve the installation workability of door internal components and simplify the door manufacturing work without the above-mentioned problems. The object of the present invention is to provide an automobile door configured to achieve the following.

[Means to solve the problem]

In order to solve the above problem, the present invention takes the following technical measures. That is, the automobile door of the present invention includes an outer panel,
On the other hand, an automobile is provided with an inner panel positioned at a predetermined interval in the vehicle width direction, and a door internal component is incorporated into a bag-shaped space formed by the outer panel and the inner panel working together. A door for a vehicle, wherein a strut portion extending inward in the vehicle width direction to an intermediate portion in the door thickness direction is integrally formed at an edge of the outer panel, and a strut portion corresponding to the strut portion is formed at an edge of the inner panel. The mounting piece extending outward in the vehicle width direction to the middle part in the door thickness direction is integrally formed with a piece, and the mounting pieces of the outer panel support and the inner panel are connected to each other by screws.

[Action and effect]

In the case of the automobile door of the present invention, unlike conventional door structures in which the outer panel and the inner panel are joined by hemming their edges in a pressing process, both panels are joined by screwing. Therefore, it is now possible to attach the door internal components to each panel before the two panels are joined, and unlike the conventional method, the door internal components are inserted into the bag-like space of the door panel from the working hole of the inner panel after the two panels are joined. Since there is no need to use the troublesome and blind installation method of inserting and fixing it to the back side of the panel, the installation work of the internal components of the door can be performed very easily. In addition, in the present invention, by forming the support column provided on the outer panel side and the mounting piece provided on the inner panel side so that each extends to the middle part in the door thickness direction, the door internal components on the outer panel side The installation is located outward in the vehicle width direction from the position in the thickness direction of one door.
Further, the door internal components on the inner panel side can be positioned inward in the vehicle width direction from the position of the support column in the door thickness direction. Therefore, the formation position of the above-mentioned support column and the installation position of the door internal components on the inch panel side are different, and the formation position of the mounting piece and the installation position of the door internal components on the outer panel side are different from the side view (vehicle width Even if the outer panel and inner panel are simply overlapped in the vehicle width direction when connecting the outer panel and the inner panel, the internal components of the door may interfere with the above-mentioned support column or mounting panel. do not have. That is, when connecting the outer panel and the inner panel, no special tricks are required when the two panels are overlapped, and the operation of connecting the outer panel and the inner panel can be easily performed. As described above, according to the present invention, it is possible to improve the workability of attaching the internal components of the door, and the work of connecting the outer panel and the inner panel can also be performed very easily. Further, in the automobile door of the present invention, which allows the attachment of the door internal components to each panel before the outer panel and the inner panel are combined, it is possible to automate the installation work of the door internal components, It is possible to significantly improve productivity. Furthermore, since there is no need to provide a working hole in the inner panel for inserting the internal door components into the bag-like space as in the past, the rigidity of the inner panel increases and the strength of the door as a whole can be increased. At the same time, it is possible to improve the support stability for the door trim attached to the inner panel. Also,
Since the support column and the mounting piece are formed to extend in the thickness direction of the door, they can have a lip-like function, which also increases the strength of the door. Moreover, in the present invention, as described above, the screw retaining portions extending in the vehicle width direction, such as struts and mounting strips, are provided at the edges of the outer panel and the inner panel, and there is no need to provide a screw securing allowance on the panel surface. The mounting position of the door internal components can be set on the entire panel surface, and it is also possible to make the area of the door glass substantially correspond to the panel area.

[Explanation of Examples]

Embodiments of the present invention will be specifically described below with reference to the drawings. The automobile door of the present invention includes an outer panel 1 and an inner panel 2 located at a predetermined interval in the vehicle width direction (door thickness direction), and the outer panel 1 and the inner panel 2 cooperate with each other. The door is constructed by incorporating the internal components of the door into the bag-like space 3 formed by the opening. In this example, a sub-outer panel 4 is attached to the inner surface (inward side surface in the vehicle width direction) of the outer panel 1, as shown in FIGS. 1 to 3. This sub-outer panel 4 has a shape corresponding to the panel shape of the outer panel 1, and has a lock side panel 1 on the rear side in the front-rear direction, as shown in FIGS. 1 and 3.
6 are connected by spot welding the sides. The sub-outer panel 4 or the lock side panel 16 is hemmed to the outer panel 1 at three sides excluding the belt line portion, so that the outer appearance of the outer panel 1 is maintained as before. There is. Further, as clearly shown in FIGS. 2 and 3, the sub-outer panel 4 has a projecting portion 5 that extends in the front-rear direction and bulges outward in the vehicle width direction.
It is provided at three locations in the vertical direction, and this overhang portion 5
By joining the inner surface of the outer panel 1 via the sealer S, the tension and rigidity of the outer panel 1 can be increased. Furthermore, the sub-outer panel 4 is provided with a plurality of weight reduction holes 6, thereby reducing the weight of the door. Note that in order to increase the strength of the outer panel 1, it is sufficient to reinforce the four sides of the outer panel 1, so the sub-outer panel 4 is configured with a frame-shaped body with a notch in the center. Good too. In this case, further weight reduction of the door is achieved. Now, in this example, as shown in FIGS. 1 and 3, on the front side of the sub-outer panel 4 in the vehicle longitudinal direction, which is provided integrally with the outer panel 1, there is a A support column 7 is formed which extends toward the base and has a screw through hole 7a formed at a predetermined position, and similarly,
Also on the rear side in the front and back direction, the support column 7 is formed by the sub-outer panel 1 and the lock side panel 16. Further, the sub-outer panel 4 is provided with a horizontal support portion 17 extending in the front-rear direction between the support portions 7 and 7 and extending inward in the vehicle width direction to the middle portion in the door thickness direction at its lower side. Also, this horizontal support portion 17 is provided with a plurality of screw holes 17a at predetermined intervals in the front-rear direction. On the other hand, the inner panel 2, which constitutes the door together with the outer panel 1, has a wall extending outward in the vehicle width direction up to the middle part in the thickness direction of the door, at a position corresponding to the pillar part 7 and the horizontal pillar part 17 at the edge thereof. For mounting, pieces 8 are provided respectively, and these pieces 8 are also mounted at positions corresponding to each screw through hole 7a of the support section 7 and each screw through hole 17a of the horizontal support section 17. , the screw through hole 8a.

connected to each other. As described above, in the case of the automobile door of the present invention, the outer panel 1 and the inner panel 2 are screwed together, unlike the conventional door structure in which both panels are joined by hemming the edges in a pressing process. Since the outer panel 1 and the inner panel 2 are connected together, the door internal components installed in the bag-like space 3 formed by the outer panel 1 and the inner panel 2 can be connected to each panel 1.2 before the two panels 1.2 are connected.
It becomes possible to install it on. That is, in this example, as shown in FIG. 1, before the outer panel 1 and the inner panel 2 are combined, the door frame 1), the door hinge 12, the door lock 18, etc. are attached to the outer panel 1, and the inner panel 2 has a window regulator 13
, door glass 14, door glass guide 15, door check 19, and other internal door components are installed in advance.
After the door internal components are attached, the outer panel 1 and the inner panel 2 are connected with the screws 9 as described above. Therefore, when installing the internal door components,
It is no longer necessary to use the conventional method of inserting the door internal components into the bag-shaped space 3 in the door panel through the working hole in the inner panel and attaching them to the back of the panel. The installation work can be done very easily. Further, the support columns 7 and 17 provided on the outer panel side and the mounting piece 8 provided on the inner panel side are each formed so as to extend to the middle part in the thickness direction of the door at the panel edge. That is, the formation position of the support column 7.17 and the mounting position of the door internal components on the inner panel side are different from each other, or the mounting position is the same as that of the piece 8.
If the formation position of the outer panel and the mounting position of the door internal components on the outer panel side overlap in side view (vehicle width direction view), when connecting the outer panel 1 and the inner panel 2, it is necessary to simply connect both panels 1.2. Even if they are stacked straight in the vehicle width direction, the door internal components and the above-mentioned support column 7,
17 and mounting are made so that there is no interference between the piece 8 and the piece 8. Therefore, when assembling the outer panel 1 and the inner panel 2, no special tricks are required and the connection work of the outer panel 1 and the inner panel 2 can be easily performed. As described above, in the automobile door of this example, the installation work of the internal components of the door is simplified, and the work of connecting the outer panel 1 and the inner panel 2 can also be easily performed. Workability in the process can be greatly improved. Moreover, in this example, the sub-outer panel 5 provided integrally with the outer panel 1 also improves the rigidity of the door. In this example, the door components such as the door weather strip 20°, the door trim 21, and the armrest (as shown) are attached after the outer panel 1 and the inner panel 2 are assembled. By the way, the scope of the present invention is not limited to the above-mentioned embodiment. For example, in the case of the above embodiment, the support portions provided on the outer panel were provided on three sides excluding the belt line portion. However, the positions of the support pillars may be arbitrarily determined depending on the structure of the door, such as only three positions, the front side and the rear side in the longitudinal direction. Further, the support portion may be provided directly on the outer panel, and the support portion and the attachment may be designed in various ways even in the shape of the piece.
