Description

The present invention relates to a vehicle body roof mounting structure.

b. Conventional technology When assembling a car body, first, the floor (underbody)
Then, the side bodies are erected on both sides thereof, the roof panel is placed from above, and the joints are fixed by welding. Therefore, when the roof panel is mounted on the side panel, it is required that the roof panel be easily mounted, the connecting portion be easily connected, and the welding workability of the connecting portion be good.

In the rear window frame portion of the four-wheeled vehicle (see the portion E in FIG. 1), a mounting structure as shown in FIG. 5 is adopted when the roof panel is mounted and fixed to the side body. That is, a is the roof panel, b is the outer panel of the side body, c is the inner panel, and the extension d of the roof panel a is fixed by spot welding on the side of the outer panel b.

c. Problems to be Solved by the Invention With the above-described structure for mounting the vehicle body roof, when the extension d of the roof panel a is spot-welded to the side of the outer panel b, the inner panel c becomes an obstacle, It is necessary to provide a hole f for inserting the spot gun e in the inner panel c in advance, and since the spot gun e is inserted into this hole f for welding, the workability in the welding operation cannot be said to be good.

d. Means for Solving the Problems The present invention has been made in view of the above circumstances, and has as its object to provide a vehicle body roof mounting structure that solves the above problems.

That is, according to the present invention, the roof panel of the four-wheeled vehicle is fixedly mounted on the upper outer panel of the left and right side bodies of the vehicle body, and the upper window frame part for assembling the side glass is formed at the side end with the end of the roof panel facing downward. In the case of, the window frame portion is an extension portion for attaching a side glass,
A rigid wall portion bent from the extension to the indoor side, and a flange portion further extended from the rigid wall portion and fixed to the outer panel, a rigid wall portion is formed at a central portion in the front-rear direction of the window frame portion. At the front and rear ends of the window frame, the outer panel is bent in the order of the extension, hard wall, and flange, and the outer panel is bent at the front and rear ends. The above problem was solved by making the extension, the hard wall, and the flange overlap at the front and rear end portions.

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

1 to 4, reference numeral 1 denotes a four-wheeled vehicle, 2 denotes a roof panel of a rear window frame portion E of the vehicle body, 3 denotes an outer panel of a side body provided on a lower portion of the roof panel 2 on both left and right sides of the vehicle. The inner panel of the body, 5
Denotes a quarter window glass as a side glass, 6 denotes a rear pillar, and 7 denotes a pillar provided at a rear portion of a rear door.

As shown in FIG. 3, the center of the window frame portion E has an extended portion 2a extending downward to a side end of the roof panel 2, a hard wall portion 2b bent from the end of the extended portion 2a to the indoor side, and Hard wall
The end portion 2b has a flange portion 2c bent substantially in parallel with the quarter window glass 5, and is formed at an angle substantially close to a right angle with the hard wall portion 2b and the flange portion 2c. For convenience of explanation, the meeting point between the extension portion 2a and the hard wall portion 2b is P1, and the meeting point between the hard wall portion 2b and the flange 2c is Q1.

The flange portion 2c is configured to abut on the extended portion 3a of the outer panel 3 of the side body and to be integrally fixed together with the inner panel 4 of the side body by spot welding. Reference numeral 8 denotes an adhesive for fixing the quarter window glass 5.

As shown in FIG. 4, the rear end of the window frame portion E is provided with a hard wall portion 2b that does not bend inward from the end portion (meeting point P2) of the extension portion 2a of the roof panel 2 but projects slightly outward. , The hard wall
The flange portion 2c is bent so as to protrude further outward from the tip end (meeting point Q2) of 2b. That is, the meeting points P2 and Q2 project outward by the width of L.

The outer panel 3 of the side body has a portion corresponding to its extension 3a and a meeting point P2, Q2 with the roof panel 2,
It is formed so as to conform to the shape of the roof panel 2.

The joining portion of the window frame portion E near the pillar 7 is also configured in the same manner as the rear end portion.

When assembling the roof panel 2 to the side body, as shown by an arrow in FIG. 4, when the roof panel 2 is lowered from above, the extension 2a, the rigid wall 2b,
Since the flange portion 2c is open to the outside of the vehicle body, it can be easily placed on the side body, and the respective meeting points P2 and Q2, that is, the flange portion 2c and the extension portion 3a easily match.
Therefore, these joints may be welded and fixed to each other.

In the vicinity of the center of the window frame, the flange 2c of the roof panel 2, the end of the inner panel 4 of the side body, and the extension 3a of the outer panel 3 may be spot-welded in a state as shown in FIG.

e. Effects of the Invention According to the vehicle body roof mounting structure of the present invention, at both ends of the window frame, the roof panel can be lowered onto the side body from above to be mounted and fixed, thereby improving workability of mounting and welding. .

In addition, the extension of the roof panel is integrated into the flanges of the inner panel and the outer panel of the side body, so that spot welding can be performed at the same time, and there is no need to provide a hole for spot gun insertion. Man-hours can be reduced.

In the vicinity of the center of the window frame, a rigid wall portion is provided at a portion from the extension of the roof panel to the flange portion, so that the same strength as in the related art can be maintained.
