Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a lower structure of a fixed door window, an example of which is a quarter window in a rear door of an automobile.

(Prior art) As exemplified in Japanese Utility Model Application Publication No. 59-78122, the quarter window has conventionally had its lower structure constructed with a fourth structure.
It was common to have a configuration as shown in the figure. That is, as shown in FIG. 4, the horizontal end portions e and f of the two-step bent portions c and d of the door outer panel a and the door inner panel b are overlapped,
These are welded by spot welding S to form a channel-shaped door glass support part g, to which the lower end of the door glass h is supported and fixed.

However, with such a structure, there is a problem that the strength and rigidity of the door are insufficient.In order to solve this problem, a door equipped with a door outer reinforcement i as shown in Fig. has also been proposed.

As shown in FIG. 5, this conventional example has a channel-shaped door glass between a joint j between a door outer panel a and a door outer reinforcement i and a two-step bent part d of a door inner panel b. A supporting portion g is formed to support and fix the lower end of the door glass h, and a door outer reinforcement i is formed.
and a horizontal portion f on the front end side of the two-step bent portion d of the door inner panel b are connected by a bracket k. In addition, in FIG. 5, S indicates a spot welding location.

(Problems to be solved by the invention) However, since the conventional example shown in Fig. 5 requires a bracket k, there are problems in that it causes a rise in parts cost, an increase in weight, and an increase in the number of spot welded parts. There is a point.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a channel between the joint between the door outer panel and the door outer reinforcement and the two-step bent part of the door inner panel. In the lower structure of a fixed door window in which a door glass support part is formed, and a lower end of a fixed door glass is supported and fixed to the door glass support part, the lower part of the door outer reinforcement has a lower end of the door glass support part. A support piece is formed by cutting and raising a portion located in the horizontal direction, and this support piece is welded to a horizontal portion on the front end side of the two-step bent portion of the door inner panel.

(Function) According to the above configuration, the door outer reinforcement and the two-step bent portion of the door inner panel can be connected by using the support piece formed by cutting and bending the door outer reinforcement. The bracket k required in the conventional example shown in FIG. 5 can be omitted.

(Example) The example of the present invention shown in FIGS. 1 to 3 is as follows:
Quarter window Q in the rear door D of a car
It is related to the lower structure of.

In the lower structure, as shown in detail in FIGS. 1 and 2, there is a joint 3 between the door outer panel 1 and the door outer reinforcement 2, and a two-step bent portion 5 of the door inner panel 4. A channel-shaped door glass support part 6 is formed between them, and the lower end of a quarter window glass (door glass) 7 is supported and fixed to this door glass support part 6 via a weather strip 8.

Support pieces 9 cut and raised in the horizontal direction at multiple locations are formed in a portion of the door outer reinforcement 2 located near the bottom of the door glass support portion 6 . It is applied to the lower surface of the distal end horizontal portion 10 of the two-step bent portion 5, and is welded to the distal horizontal portion 10 by spot welding P. Note that the door outer panel 1 and the door outer reinforcement 2 are spot welded P at their joint 3.
is applied.

Thus, according to the above configuration, since the rear door D is provided with the door outer reinforcement 2, its strength and rigidity are improved, while the support piece 9 formed by cutting the door outer reinforcement 2 is utilized. As a result, the door outer reinforcement 2 and the two-step bent portion 5 of the door outer panel 4 can be connected, so that the bracket k required in the conventional example shown in FIG. 5 can be omitted. Therefore, according to the above structure, by omitting the bracket k, it is possible to reduce the cost and weight of parts compared to the conventional example shown in FIG. It is possible to improve the

The present invention can be configured in various ways other than those shown in the above embodiments. For example, a support piece 9 formed by cutting and raising the door outer reinforcement 2
The number and shape of the support pieces 9 are not limited to those shown in the above embodiments, and the support pieces 9 may be overlapped and welded to the upper surface of the front end side horizontal portion 10 of the door inner panel 4.

(Effects of the invention) Since the present invention has the above-mentioned structure and function, it is possible to create a fixed type window that has excellent strength and rigidity by being equipped with a door outer reinforcement, and is advantageous in terms of parts cost, weight reduction, and work efficiency. can provide the undercarriage.
