Description

Description: TECHNICAL FIELD The present invention relates to a method of assembling an automobile door. [Prior Art] In general, the body of an automobile is described, for example, in the book of Automotive Engineering, Vol.
Manufacturing method of rolled car: 178P issued by Sankaido on April 20, 1980
As is clear from the description of ~ 179P, various body members and panel materials are sequentially joined to form a white body,
This is sequentially transferred to the painting process, and finally various functional parts and interior parts are assembled, and the door is similarly assembled. In other words, the door is assembled by joining the end flanges of the door inner panel and the door outer panel, which are press-molded, and then transferred to the painting process and the outfitting process in order, and finally the various functions such as the wind panel elevating mechanism The parts are attached to the door inner panel side. (The Complete Book of Automotive Engineering, Vol. 13, Automobile Body: See pages 93 and 134, published by Sankaido on April 20, 1980). [Problems to be Solved by the Invention] As described above, the window panel lifting mechanism for raising and lowering the window panel (glass) is mounted on the inner panel side of the door. In this case, the window panel and the door outer panel are connected to the door waist portion. In this case, a continuous egg shell style having no steps is preferable in terms of molding and aerodynamic characteristics. For this purpose, for example, the window panel is mounted as close as possible to the outer panel. However, in order to avoid interference with the door outer panel, a play allowance between the door outer panel and the window panel is required to be greater than a predetermined value. Therefore, the assembling space inside the door is expanded by the play allowance, the window glass, and the thickness of the elevating mechanism, so that the door inner panel is pressed toward the passenger compartment. For this reason, a problem that affects the vehicle interior space occurs. On the other hand, in order to achieve the egg shell style, for example, it is desirable to apply the means described in Japanese Patent Application Laid-Open No. Sho 57-143073 in which the window panel lifting mechanism is the door inner panel side and the window panel is the door inner panel side. But,
The window panel elevating mechanism is configured to be attached to the outer panel side in order to avoid interference between the elevating mechanism and the outer panel when the window panel is lowered. In this case, since the assembling work of the elevating mechanism is performed from the working hole of the door inner panel to the outer panel side at the back, the work space is restricted, making the work difficult and troublesome, resulting in poor workability. Accordingly, it is an object of the present invention to provide an assembling method capable of assembling a door matching an egg shell style with good workability. [Means for Solving the Problems] In order to achieve the above object, the present invention provides a door inner panel and a door outer panel formed in an arc shape toward the outside, respectively, and an upper end portion of a guide rail. The window panel is supported on the door inner panel by a support means for rotating the lower end of the window panel outward at the highest position with the door as the center, and the door outer is attached to the door outer panel by attaching the window panel elevating mechanism to the door outer. After coupling with the door inner, the window panel on the door inner panel side is linked to the window panel elevating mechanism. [Operation] According to the door assembling method, the window panel and the window panel elevating mechanism are separately mounted on the door inner panel and the door outer panel in the respective open spaces. It is configured as an outer unit. At this time, the work can be mounted by laying both panels vertically or horizontally, and a free working posture can be taken. Therefore, the work can be performed easily and easily, and the assembly can be automated. In addition, since the window panel can be moved to the door outer panel side and assembled, an egg shell style can be obtained, and the window panel lifting mechanism can be attached to the door outer panel bulging outward, so that the door inner panel can be attached to the door outer panel. It is possible to move to the side, and the room space can be expanded accordingly. Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings of FIGS. In the drawing, reference numeral 1 denotes a door of an automobile. The door comprises a door inner panel 3 and a door outer panel 5 which are separately press-formed, and a terminal flange portion 7 of the door outer panel 5 is formed.
The terminal flange 9 of the door inner panel 3 is joined and fixed by bolts 11 and nuts 13. The door inner panel 3 is provided with a working hole 3a and a sash 3b, and the terminal flange portion 9 has a shape formed continuously and integrally with the panel body. Further, the terminal flange portion 7 of the door outer panel 5 is formed separately from the panel main body, and is provided over the front and rear and lower regions excluding the door waist portion 15 and the terminal end portion of the panel main body is hemmed.
By doing so, it is connected and fixed to the door outer panel 5. On the other hand, the door outer panel 5 is formed in an arc shape toward the outside as shown in FIG.
19, and a window panel lifting mechanism 21 is mounted on the base plate 19 to form a door outer OU, thereby forming an outer unit. The base plate 19 is formed along the curvature of the door outer panel 5, and an upper region of the door waist portion 15 is supported by an S-shaped clip 23. In addition, the end portions of the front and rear and lower regions of the base plate 19 are connected to the end flange portions 7.9 of the door outer panel 5 and the door inner panel 3, respectively.
The bolts 11 and nuts 13 for joining and fixing the terminal flange portions 7 and 9 of the door outer panel 5 and the door inner panel 3 are overlapped and connected. The window panel elevating mechanism 21 includes a driving unit 25 such as a motor.
27, a sector gear 29 meshing with the pinion 27, a main arm 31 fixed to the sector gear 29, and two sub-arms 35 formed in an X-shape with the main arm 31 and supported by the shaft 35. 37, 39, slide rollers 41, 43, 45 supported at the free end of the main arm 31 and each end of both sub-arms 37, 39, and slide rollers 41 of the main arm 31 and the sub-arms 37, 39, respectively. , 43 are in sliding contact with each other, and have an upper slide rail 49 to be bolted to a lower end portion of a glass holder 47 to be described later, and a lower slide rail 51 in which the slide roller 45 of the sub arm 39 is in sliding contact with each other. Installed on 19. On the other hand, a glass holder 47 is provided on the door inner panel 3 side.
