Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a door structure for a vehicle such as an automobile.

[Conventional technology]

Conventionally, there have been a sash door D' as shown in FIG. 6 and a press door D'' as shown in FIG. 7 as doors for automobiles.

In the door sash door D' shown in FIG. 6, the door sash portion 2 above the belt line BL of the door body 1 is entirely formed of a roll-formed product.

Furthermore, the play door D'' shown in FIG. 7 is constructed entirely of a press-molded product such that the door body 1 and the upper portion 1a of the door body 1 above the belt line BL are integrated.

Note that the reference numeral 3 in FIGS. 6 and 7 indicates a door glass that can be raised and lowered.

[Problem that the invention attempts to solve]

However, in the conventional door sash door D' shown in FIG. 6, the door sash section 2 is entirely made of roll-formed products, so while the entire door sash section 2 can be finished slim, there are changes in the cross section at various parts of the door sash section 2. The degree of freedom is small, and at most the width of the rear edge of the door sash section 2 can be slightly changed vertically.

In addition, in the conventional press door D'' shown in Fig. 7,
Since the entire door is made of press-molded products,
Although it is possible to freely create the cross-sectional shape of each part of the door upper part 1a, it is not possible to make the upper part of the door slim.

The present invention attempts to solve these contradictory problems, and aims to provide a vehicle door structure that uses roll-formed products and press-formed products in the right places.

[Means for solving problems]

Therefore, in the vehicle door structure of the present invention, in a vehicle door composed of a door body and a door sash portion above the belt line of the door body, the rear edge portion of the door sash portion serves as a door glass elevation guide portion. is composed of a press-formed product, and the front edge and upper edge of the door sash section, which serve as door guide holding parts, are composed of an integral roll-formed product, and the upper end of the rear edge and the rear of the upper edge It is characterized in that the ends are connected to each other.

[Effect]

In the above-mentioned vehicle door structure of the present invention, the rear edge portion as the door glass elevating guide portion in the door sash portion is made of a press-molded product, and
Since the front edge and upper edge of the door glass holding part of the door sash section are made of an integral roll-formed product, the front edge and upper edge of the door glass holding part can be finished slim. At the same time, it is possible to freely set the change in the cross-sectional shape of the rear edge portion as the door glass lifting guide portion.

〔Example〕

Hereinafter, a vehicle door structure as an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a side view of a front door having this structure, and Fig.
Figure 3 is a sectional view taken from the - arrow in the figure, and Figure 3 is -
4 is a partial perspective view showing the joint structure of the parts shown in FIG. 1, and FIG. 5 is a side view of the door corresponding to FIG.
In FIG. 5, the same reference numerals as in FIGS. 6 and 7 indicate substantially similar parts.

In this embodiment as well, as shown in FIG.
The door sash section 2 is provided above the belt line BL of the door sash section 2, but the door sash section 2 is different from the conventional one in that the door sash section 2 is constructed by combining a press-formed product and a roll-formed product.

That is, the rear edge part 2B as a door glass elevating guide part in the door sash part 2 is made up of an inner panel 2B-1 as a press-molded product and an outer panel 2B-2 as a press-molded product, and the door glass holding part in the door sash part 2 is The upper edge 2A and the front edge 2C, which are the parts that hold the door glass 3 when the door glass 3 is raised, are made of an integral roll-molded product.

The upper end of the rear edge 2B as a press-formed product and the rear end of the upper edge 2A as a roll-formed product are then joined together as shown in FIG. 4.

The cross-sectional shape of the rear edge 2B of the door sash section 2 is as shown in FIG. 3, and the cross-sectional shape of the front edge 2C (upper edge 2A) of the door sash section 2 is as shown in FIG.

Furthermore, a sealing member 4 is provided at the door glass holding portion of the upper edge 2A and front edge 2C of the door sash 2 to seal the door glass 3 and the upper edge 2A and front edge 2C of the door sash 2. At the same time, a sealing member 5 for sealing the door glass 3 and the rear edge 2B of the door frame 2 is provided at the door glass elevation guide portion of the rear edge 2B of the door frame 2.

With the above-mentioned configuration, the portion between a and b that only holds the door glass 3 (i.e., the upper edge 2A and front edge 2C portion of the door sash portion 2) is formed of a roll-formed sash, while the door glass 3
Even if the part between b and c (i.e. the rear edge part 2B of the door sash part 2), which becomes the lifting guide for the The upper edge 2A and the front edge 2C of the door sash 2 can be made slim while giving the required strength, and the area between b and c (the rear edge 2B of the door sash 2) can be made slim. The cross-sectional shape can be freely changed, which makes it easy to use the rear edge 2B of the door sash 2 as a member for installing seatbelt anchors, door speakers, ventilation, etc.

Furthermore, as shown in Fig. 5, the door sash section 2
It is also easy to curve the inner portion of the rear edge portion 2B, which increases the degree of freedom in design.

Furthermore, it goes without saying that this structure can be similarly applied to doors for vehicles other than automobiles.

[Effect of idea]

As described in detail above, according to the vehicle door structure of the present invention, in a vehicle door composed of a door body and a door sash portion above the belt line of the door body, a door glass elevating guide in the door sash portion is provided. The rear edge of the door sash section is made of a press-formed product, and the front edge and upper edge of the door guide holding part of the door sash part are made of an integral roll-formed product. Since the rear end of the upper edge is connected to the rear end of the upper edge, the front edge of the door sash and the upper edge of the door sash, which only hold the door glass, can be made slim with the required strength. The vertical cross-sectional shape of the rear edge of the door sash, which serves as a lifting section, can be freely changed, allowing the rear edge of the door sill to be used for various purposes (for example, as a seatbelt anchor attachment section, a door speaker attachment section, or a ventilation arrangement). This has the advantage of increasing the degree of freedom in design since the side shape of the rear edge of the door sash can be selected arbitrarily.
