Description

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

b. Prior Art Conventionally, as shown in Automotive Engineering Complete Book Vol. 13 "Passenger Car Body", the structure around the door of an automobile has been such that the door body is composed of a door inner panel and a door outer panel, and the door inner panel is An inside handle and an outside handle, which are operation handles for opening and closing the door, are attached to the panel and the door outer panel, respectively.

c. Problems that the invention aims to solve However, in the conventional structure as described above, the area around the opening for advancing and retracting the window glass, which is the waist part of the door body, is vulnerable to forces from the width direction of the vehicle, and the door body is If you put your hands on the waist area and use strong force to close or open the bag, there will be no tension and rigidity, which may result in a loss of quality. On the other hand, since the door inner panel and the door outer panel are made of thin steel plates, the handle support rigidity is weak, and in short, the panels become sticky when operated with strong force. To solve this problem, we applied a patch (reinforcing plate) to the back of the handle attachment.

Another problem was that the door panel could not be made thinner in order to ensure the rigidity of the door body, making it difficult to meet social demands for weight reduction.

Therefore, the present invention aims to improve the handle support rigidity with a lightweight and simple structure.

d. Means for Solving the Problems In order to achieve the above object, the present invention provides a structure in which a rain hose forming a closed cross section is fixed to the waist portions of the door inner panel and the door outer panel, and the door inner panel of the rain hose is fixed to the waist portion of the door inner panel and the door outer panel. Alternatively, at least one lower end of the door outer panel side may be extended downward along the door panel, and a handle attachment portion may be formed in the extension portion.

e Example In FIGS. 1 and 2, the door body 1 is composed of a door inner panel 2 and a door outer panel 3. Rain hoses 4 and 5 forming a closed cross section are fixed to the waist portions of the door inner panel 2 and the door outer panel 3, respectively, and the lower end of the rain hose 4 on the inner panel 2 side is connected to the door inner panel 2.
The inside handle 6 is integrally extended downward along the extension portion 4a, and a mounting portion 7 for the inside handle 6 is formed in the extension portion 4a. In the inside handle attachment part 7, as shown in detail in FIG. 3, the door inner panel 2, the escutcheon 6a of the inside handle 6, and the extension part 4a of the rain hose 4 overlap so that the door inner panel 2 is sandwiched. The mounting bolt 8 inserted into the insertion hole 6a ₁ formed in the escutcheon 6a and the insertion hole 2a formed in the door inner panel 2 is attached to the extension part 4a of the rain hose 4.
An inside handle 6 is attached by being screwed into a screw hole _4a1 formed in the inside handle 6. 6b is a handle portion of the inside handle 6, and 9 is a window glass.

With this configuration, since the extension part 4a of the rain hose 4 overlaps the mounting part 7 of the inside handle 6, the handle support rigidity is significantly improved, and the lower end of the rain hose 4 only needs to be slightly extended integrally. , it is lightweight and has a simple structure.

FIG. 4 shows another embodiment of the invention.

This example differs from the first embodiment in that the lower end of the rain hose 5 on the door outer panel 3 side is extended downward along the outer panel 3, and the attachment part 11 of the outside handle 10 is formed in the extension part 5a. There is. At the attachment part 11 of the outside handle 10, the outside handle 10
is attached with a mounting bolt 12. According to this example, in addition to having the effects of the first example, the supporting rigidity of the outside handle 10 is also improved.

In addition, in this invention, the door outer panel 3
Only the rain hose 5 on the side may be provided with an extension portion 5a, and the attachment portion 11 of the outside handle 10 may be provided on this extension portion 5a.

f Effects As described above, according to the present invention, it is possible to obtain the effect that the handle support rigidity is improved with a lightweight and simple structure.
