Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of an armrest typically provided on a side door in a vehicle such as a passenger car.
[0002]
[Prior art]
In this type of vehicle, for example, as shown in FIG. 4, the armrest 3 is usually arranged at a predetermined portion of the door trim 2 inside the side door 1. The armrest 3 is provided in a form protruding moderately by the door trim 2 so that an arm or an elbow can be placed thereon. In addition, an assist grip 4 used for opening and closing the door, a switch 5 for opening and closing the side window, and the like are disposed at predetermined portions of the armrest 3.
[0003]
5 and 6 show a specific configuration around the armrest 100 as a conventional example. In the figure, 101 is a door trim body, 102 is an armrest base, and 103 is an assist grip. Reference numeral 104 denotes a switch unit including a plurality of switches, and reference numeral 105 denotes a switch base. In FIG. 5, the three-axis arrow F indicates the front, the arrow U indicates the upper direction, and the arrow C indicates the center direction.
[0004]
Many of these components, that is, the door trim main body 101, the armrest base 102, the switch base 105, and the like are made of synthetic resin and are formed by a molding die using a synthetic resin material.
[0005]
As shown in FIG. 6, the attachment structure when assembling or attaching each component member, particularly in the front side portion of the assist grip 103, is unevenly fitted to the recess 102 a of the armrest base 102. And it fastens with the tapping 107 (2 places) via the reinforce 106. Further, at the rear side portion of the assist grip 103, the protruding end portion of the assist grip 103 is inserted into the insertion hole 102b of the armrest base 102, and is fastened by the spring nut 108 and the tapping 109 (one place) through the reinforcement 106. Like that.
[0006]
[Problems to be solved by the invention]
In the conventional door armrest structure, particularly when the armrest base 102 is manufactured, a slide mold is necessary for the mold. That is, since the armrest base 102 has the recess 102a and the insertion hole 102b for engaging with the assist grip 103, in order to mold these parts, a slide mold is used with respect to the mold release direction B at the time of molding. I had to use it. In addition, the spring nut 108 and the like are required as a component structure, and the number of components has to be increased.
[0007]
SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a door armrest structure that can simplify the configuration and realize a reduction in the number of parts and simplification of a mold.
[0008]
[Means for Solving the Problems]
The present invention is a door armrest structure in which an armrest is arranged at a predetermined portion of a door trim, and an assist grip is directly attached and fixed to the door trim main body through reinforcement, and the direction in which the assist grip is attached is a mold at the time of molding the door trim main body. The arm rest cover is attached to the door trim body so as to cover the assist grip attaching portion so as to be the same as the pulling direction.
[0009]
According to the present invention, the assist grip is attached and fixed directly to the door trim body via the reinforcement. In this case, the assist grip is attached in the same direction as the door trim body at the time of molding, so that a slide mold of the assist grip attaching portion is not required.
Further, when attaching and fixing the assist grip, it can be fastened without using parts such as a spinning nut by tapping on the reinforcement burring hole.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of a door armrest structure according to the present invention will be described with reference to the drawings.
FIG. 1 shows a specific configuration around the armrest 10 in this embodiment. In the present embodiment, as shown in FIG. 4, the armrest 10 may be arranged and configured at a predetermined portion of the door trim 2 inside the side door 1 described above. In addition, the armrest 10 is provided in the form which protrudes moderately in the door trim 2 so that an arm or an elbow etc. can be put.
[0011]
In FIG. 1, 11 is a door trim body, 12 is an armrest cover, 13 is an assist grip, and 14 is a switch unit having a plurality of switches. In FIG. 1, the arrow F in the triaxial direction indicates the front, the arrow U indicates the upper direction, and the arrow C indicates the center direction.
[0012]
In the present invention, the assist grip 13 is attached and fixed directly to the door trim main body 11 via a later-described reinforcement. In this case, the direction in which the assist grip 13 is attached is the same as the direction in which the door trim body 11 is molded.
[0013]
Here, an attachment structure when assembling or attaching each component in FIG. 2 will be described. The door trim main body 11 and the reinforcement 15 are preferably fastened by tapping 16 at two places. Then, the assist grip 13 is set, and the attachment portion 13a is fastened by tapping 17 to the burring hole of the reinforcement 15. Thereafter, the armrest cover 12 is attached to the door trim main body 11 so as to cover the attachment portion 13a of the assist grip 13.
[0014]
In the door armrest structure according to the present invention, the switch unit 14 is attached to the armrest cover 12 as shown in FIG. That is, the switch base on which the switch unit 14 is mounted is configured to be integrated with the armrest cover 12.
[0015]
According to the present invention, the assist grip 13 is attached and fixed directly to the door trim body 11 via the reinforcement 16. Since the switch base and the armrest cover 12 can be integrated, the number of parts is reduced by simplifying the structure. In addition, since the mounting direction of the assist grip 13 is the same as the direction of mold release when molding the door trim main body 11 (FIG. 2, arrow B), this allows the assist grip 13 in the door trim main body 11 to be mounted. A molding slide mold becomes unnecessary.
[0016]
Further, when the assist grip 13 is attached and fixed, the burring hole of the reinforcement 16 is used and fastened to the assist grip 13 by tapping 17. Thereby, it can fasten without using components, such as a spring nut. In this respect as well, the number of parts is reduced.
[0017]
Although the present invention has been described based on the embodiment shown in the drawings as described above, the present invention is not limited to this embodiment and can be appropriately changed within the scope of the present invention.
For example, the specific shape and the like of the assist grip 13 are not limited to those shown in the drawings, and various other shapes can be employed, and the same effects as those in the above embodiment can be obtained.
[0018]
【The invention's effect】
As described above, according to the present invention, in this type of door armrest structure, the assist grip is attached and fixed to the door trim main body so that the mounting direction of the assist grip is the same as the die-cutting direction when the door trim main body is molded. . As a result, the number of parts can be effectively reduced, and the manufacturing mold can be simplified. As a result, there is an advantage that the manufacturing cost or the product cost can be substantially reduced.
