Abstract

PURPOSE:To assemble with a good assembling efficiency while securing the sealing property of the upper body and the lower body. CONSTITUTION:The rigidity of a roof unit 11 is increased by adhering and fixing a rear window glass 47 to the roof unit 11 except for the lower edge part 47a. Since the rigidity of the roof unit 11 is increased, the assembling efficiency to a rear body unit 12 is improved. The adheswe to adhere the rear window glass 47 to the rear body unit 12 is spread. The lower edge part 47a of the rear window glass 47 is adhered and fixed to the rear body unit 12 by using the adhesive. The adhesive functions also as a sealing material.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile body assembly method for assembling an upper vehicle body having a roof portion to a lower vehicle body.

0002

[Prior Art] For example, as described in Japanese Utility Model Application Publication No. 62-105876, an upper body (upper body) constituting the upper part of the vehicle body and an underbody (lower body) constituting the lower part of the vehicle body are interconnected. It is known that an automobile body is constructed by assembling various parts such as a seat on the underbody, and then the upper body and the underbody are mutually connected.

0003

[Problem to be Solved by the Invention] However, when assembling various parts and then fastening and fixing the underbody and upper body to form a vehicle body, it is difficult to assemble accurately and easily. For this purpose, the upper and lower car bodies must have a certain degree of rigidity. Furthermore, when joining the upper body and underbody, it is necessary to ensure sealing between them.

[0004] The present invention provides a method for assembling an automobile body, which ensures a good seal between an upper body and a lower body and allows for easy assembly.

[0005]

[Means for Solving the Problems] The present invention is based on an automobile body assembly method in which an upper body having a roof portion is assembled to a lower body. Apply adhesive to adhere the lower edge of the rear window glass to the lower body of the vehicle.
The upper vehicle body is attached to the lower vehicle body, and the lower edge of the rear window glass is adhesively fixed to the lower vehicle body using adhesive.

[0006]

[Operation] Since the rear window glass is adhesively fixed to the upper vehicle body except for the lower edge, the rigidity of the upper vehicle body is ensured by the rear window glass.

[0007] Since the lower edge of the rear window glass is adhesively fixed to the lower vehicle body via an adhesive, the sealing property of that portion is ensured by the adhesive.

[0008]

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 1 showing the overall configuration, reference numeral 1 denotes a car body, and the underbody (lower car body) side includes a chassis unit 2 extending in the longitudinal direction of the car body, and a frame having a hat-shaped cross section forming a closed cross-sectional structure. The floor unit 5 is comprised of a floor unit 5 which has frames 3, 3 on the lower surface side of a floor panel 4, and on which a front seat (not shown) is placed. On the other hand, the upper body (upper part of the vehicle body) side includes a front body unit 7 that constitutes the front part of the vehicle body including the engine room 6, a roof portion 8, and a dash panel 10 that partitions the engine room 6 and the vehicle interior 9. The roof unit 11 and the rear seat (
(not shown) is placed thereon and is divided into three rear body units 12 constituting the rear part of the vehicle body.

The chassis unit 2 has left and right frames 14, 14 extending in the longitudinal direction of the vehicle body, which are disposed in parallel, and whose front and rear ends are connected by cross members 15, 16. Spring receivers 17, 17, 18, 18 of a suspension device (not shown) are protruded near the front and rear ends of the frames 14, 14. Furthermore, in the middle part of each frame 14, there are four convex portions 19 for fastening and fixing the roof unit 11 to the chassis unit 2.
19, 20, 20 are formed.

The roof unit 11 also has an opening 21 below which a front window (not shown) is attached.
Convex portions 22, 22 protruding forward are formed. The rear portion of the front body unit 7 is fastened and fixed to the roof unit 11 via the convex portions 22, 22.

Furthermore, the roof unit 11 includes front pillars 23, 23 and a hinge pillar continuous to the lower side thereof.
24, 24, center pillar 25, 25 and rear pillar 2
It has 6,26. And those pillars 24, 24, 2
The lower ends of 5 and 25 are connected to the frame 1 of the chassis unit 2.
Convex portions 19, 19, 20, 2 projecting upward from 4, 14
0 through an adhesive and fastened and fixed with bolts.

The rear pillar 11 also has a hollow engagement convex portion 41 projecting downward at its lower end, and is fastened and fixed to the rear body unit 12 in the same manner. That is, as shown in FIGS. 2 and 3, a nut 45 is provided on the upper side of the rear fender 43 and inner panel 44 of the rear body unit 12 in correspondence with the engaging convex portion 41, and on the outer surface on the outer side of the vehicle body. With the welded engagement recess 42 fixed and the engagement protrusion 41 engaged with the engagement recess 42, the opening of the inner panel 44 and the opening 42a of the engagement recess 42 are opened from the inside of the vehicle body.
, 42a to fasten and fix the bolt 46 to the nut 45.

Rear pillars 26, 2 of roof unit 11
6, a rear window glass 47 is fixed with adhesive except for the lower edge 47a. Then, as shown in FIG. 4, the lower edge 47a of the rear window glass 47 is adhered onto the closed cross-sectional structure composed of the upper panel 49 and the lower panel 50 that constitute the rear package tray 48 on the rear body unit 12 side. be done. This adhesive 51 is applied to the vicinity of the engagement recess 42, and the adhesive 51 also ensures a seal at the joint between the roof unit 11 and the rear body unit 12. It has become.

Therefore, first, the upper edge portion 47b and both side edge portions 47c, 47c of the rear window glass 47 are adhesively fixed to the roof unit 11.

Then, the adhesive 51 is continuously applied to a portion of the rear body unit 12 corresponding to the joint portion of the rear window glass 47 and the vicinity of the portion where the rear pillars 26, 26 are joined.

Then, the roof unit 11 is coupled to the rear body unit 12 by engaging the engagement protrusion 41 with the engagement recess 42. This allows the adhesive to be fixed. At the same time, it is fastened and fixed with nuts 45 and bolts 46. At this time, since the rear window glass 47 is adhesively fixed to the roof unit 11, the rigidity of the roof unit 11 is ensured, and the assembly is easy and the assemblability is improved.

Furthermore, the adhesive 51 functions as a sealing material and can ensure sealing between the roof unit 11 and the rear body unit 12.

[0019]

[Effects of the Invention] In the present invention, since the rear window glass is adhesively fixed to the upper vehicle body except for the lower edge, the rigidity of the upper vehicle body is ensured by the rear window glass, and the upper vehicle body can be assembled to the lower vehicle body. Improves ease of assembly.

Furthermore, since the lower edge of the rear window glass is fixed to the lower vehicle body using an adhesive, the adhesive functions as a sealing material in that area.
Sealing performance at the joint portion is ensured.
