[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door latch fixing structure for an automobile door, and more particularly, to an improved door latch fixing structure for an automobile door intended to improve the appearance of the door latch fixing portion visible when the door is opened.

[0002]

[Prior art]

 At the end face portion of the hinge type automobile door a as shown in FIG. 6, a door latch c that engages with a striker (not shown) attached to the door opening portion of the body b is arranged on the inner surface of the door inner panel d. The door inner panel d is formed with a notch e for inserting the striker.

Heretofore, the door latch c has heretofore been joined to the inner surface of the door inner panel d via a reinforcement f as shown in FIG. 7 and inserted into a screw insertion hole g opened in the door inner panel d. It is adapted to be fixed to the inner panel d by being screwed into a plurality of (for example, three) setscrews h. Such a fixed structure of the door latch is also found in Japanese Utility Model Laid-Open No. 60-77670.

[0004]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional example, as shown in FIG. 6, a plurality of setscrews h are exposed on the outer surface of the door inner panel d constituting the end surface portion of the automobile door a, and these are set when the door is opened. However, there was a problem in that the set screw h of the hose disturbs the appearance by making it obtrusive.

Further, the set screws h and the screw insertion holes g through which the set screws h are inserted are located on the end face portion of the automobile door a, and are easily wetted when washing the vehicle or during rain, so that rust is likely to occur. That is also a problem.

Therefore, the present invention can improve the appearance of the door end surface that is visible when the door is opened. In addition, the set screw for fixing the door latch and the rust of the screw insertion hole of the door inner panel through which the set screw is inserted are prevented. It is an object of the present invention to provide a door latch fixing structure for an automobile door that can also suppress the occurrence.

[0007]

[Means for Solving the Problems]

 For this purpose, the door latch fixing structure of the automobile door according to the present invention has a notch corresponding to the notch for the striker of the door inner panel and is provided with a reinforcement that overlaps with the inner surface of the door inner panel. The door latch is fixed by screws, and the reinforcement is fixed by screws on the parts of the door inner panel covered by the door trim and the weather strip.

In addition, the door latch fixing structure for an automobile door according to the present invention uses the reinforcement member integrally formed with a reinforcing plate that reinforces the opening of the door inner panel.

[0009]

[Action]

 With such means, the set screw for fixing the reinforcement to which the door latch is screwed and fixed to the inner surface of the inner panel and the screw insertion hole of the inner panel through which the reinforcement is inserted are covered with the door trim or the weather strip, and the door end surface is covered. It will not be exposed on the outer surface of the door inner panel that forms the part.

[0010]

【Example】

 Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a cross-sectional view of an end surface portion of an automobile door 1 to which an embodiment is applied. In the drawing, reference numeral 2 is a door outer panel, reference numeral 3 is continuous with the door outer panel 2, and an end surface portion and an inner surface of the automobile door 1. Reference numeral 4 denotes a door inner panel that constitutes a part, a reference numeral 4 denotes a door trim that covers the door inner surface side portion 3a of the door inner panel 3, and a reference numeral 5 denotes a weather strip attached to the door end surface side portion 3b of the door inner panel 3.

Further, as shown in FIG. 2, the door inner surface 3 of the door inner panel 3 is provided with a notch 3c through which a striker mounted in a door opening of a body (not shown) is inserted. There is.

Here, as shown in FIGS. 1 and 3, a reinforcement 6 is provided so as to overlap with the inner surface of the door inner panel 3 from the door inner surface side portion 3a to the door end surface side portion 3b. . The reinforcement 6 is configured such that the door latch 8 is screwed and fixed by a set screw 7 which is inserted into three screw insertion holes 6a provided in the central portion. The reinforcement 6 is formed with a notch 6b that overlaps with the notch 3c of the door panel 3, and screws are provided at two locations above and below the one end facing the door inner surface side portion 3a covered by the door trim 4. Holes 6c, 6c are formed, and screw holes 6d, 6d are formed at two positions above and below the other end of the door end face side portion 3b facing the part covered by the weather strip 5.

Correspondingly, the door inner panel 3 is provided with screw insertion holes 3d, 3d corresponding to the screw holes 6c, 6c of the reinforcement 6 in the door inner surface side portion 3a. Screw insertion holes 3e, 3e corresponding to the screw holes 6d, 6d of 6 are formed in the portion of the door end face side portion 3b covered by the weather strip 5. Then, the set screws 9 and 9 inserted through the screw insertion holes 3d and 3d are screwed into the screw holes 6c and 6c, and the set screws 10 and 10 inserted into the screw insertion holes 3e and 3e are screwed into the screw holes 6d and 6d. By doing so, the door latch 8 as well as the reinforcement 6 is fixed at a required position on the inner surface of the door inner panel 3.

In the door latch fixing structure for an automobile door according to the embodiment configured as described above, the fixing screws 9 and 10 for fixing the reinforcement 6 to which the door latch 8 is screwed and fixed to the inner surface of the door inner panel 3 are fixed. Of these, the set screw 9 is covered by the door trim 4, and the set screw 10 is covered by the weather strip 5 so that it is not exposed to the outer surface of the door end face side portion 3b.

Therefore, as shown in FIG. 2, the notch 3c formed in the door inner panel 3 is only visible at the end surface portion of the automobile door 1 that is visible when the automobile door 1 is opened, and the appearance thereof is improved. .

Further, the set screws 9, 9 and the screw insertion holes 3d, 3d for inserting them are covered by the door trim 4, and the set screws 10, 10 and the screw insertion holes 3e, 3e for inserting them are weather strips. Since it is covered with No. 5, it does not get inadvertently wet even when washing or raining, and rust generation is suppressed.

As shown in FIG. 4, a door inner panel 3 has a door inner surface side portion 3a having a large opening, and a door regulator 12 is attached to a reinforcing plate 11 horizontally installed in the opening. In 1, the reinforcement 6 is preferably integrally formed with the reinforcement 6.

[0018]

[Effect of device]

 As described above, according to the present invention, the set screw for fixing the reinforcement to which the door latch is screwed and fixed to the inner surface of the door inner panel and the screw insertion hole of the door inner panel through which this is inserted are a door trim or a weather strip. It is not exposed on the outer surface of the door inner panel that is covered with the door and constitutes the door end surface. Therefore, it is possible to improve the appearance of the end surface of the door when the door is opened, and it is possible to suppress the occurrence of rust on the set screw and the screw insertion hole.
