Description

[Detailed Description of the Invention] This invention relates to an arrangement structure for wiring, piping, etc. to the back door of an automobile.

Generally, when a wiper or the like is attached to a bank door of a car that has a back door such as a liftback type, the washer hose and wire harness connected to the wiper need to have slack at the joint between the body and the bank door. 11, which is exposed to the interior from the rear of the body, is wired and piped to the back of the back door and connected to the wiper, which not only looks bad, but also poses a risk of coming into contact with the head of the person sitting in the back seat. There were some drawbacks.

However, there was no effective method to dispose of this type of wire harness and washer hose without directly exposing them to the indoor side, and the development of this method was delayed.
-26733, Utility Model Application Publication No. 53-121650).

This invention was developed in view of the above-mentioned current situation, and the structure of this invention will be explained below according to an embodiment shown in the drawings.

1, 1 is the rear part of the car body, 2 is the inner plate of the back door attached to the rear body part 1 so as to be openable and closable, and 3 is a hole provided in the back door 2, which will be described later. The fan-shaped recess at one end of the protective member is fitted into the protective member.

4 is the hinge center of the hinge for opening and closing the back door, 5 is a cover member fixed to the rear part 1 of the body as necessary, and its shape is a curved gutter-like shape as shown in Fig. 2; The material forming the cover member 5 is soft polyethylene, and its wall thickness is made thin so that it bends when it interferes with the head of a person sitting on the rear seat.

Reference numeral 6 designates a protective member, which is curved in shape as shown in FIG. ing.

Reference numeral 9 denotes a wire harness and a washer hose that are wired and piped from the spaces between the inner and outer panels 1a and 1b of the rear body portion 1 through the protection member 6 to the inner panel 2 of the back door.

A hole 10 is also formed in the inner plate 1a of the rear body portion 1.

In the above configuration, in order to wire and pipe the wire harness and washer hose from the rear of the body to the back door, first fit the fan-shaped recess 7 at one end of the protective member 6 into the hole 3 of the inner plate 2 of the back door, and then One end of 6 was fitted to Riki 4! The protection member e is allowed to rotate independently by the width t of the fan-shaped recess T using point a as a fulcrum.

Next, the wire harness and washer hose 9 are passed through the hole 10 of the inner plate 1a of the rear body part 1 through the inside of the protective member 6, and wired and piped to the wiper (not shown) attached to the inner plate 2 of the back door. Then, a cover member 5 is placed around the protection member 6, and this cover member 5 is attached to the inner plate 1 of the rear body portion 1.
Fix it to a.

In this state, when the back door is opened as shown by the one-dot chain line and the two-dot chain line in FIG. (the left end in Fig. 1) is the inner plate 1a of the rear body part 1.
It rotates while slidingly in contact with the cover member 5, and one end thereof protrudes from the cover member 5 to prevent the wire harness and washer hose from being exposed to the outside when the back door is opened.

As described above, the protection member 6 of the present invention has one end that fits into the hole 3 of the back door inner plate 2 as a fan-shaped recess that expands in the same direction as the opening/closing direction of the bank door, and the protection member has a width of the fan-shaped recess. Since the protection member 6 can rotate independently by the width t of the wide end of the fan-shaped recess using the narrow end point a as a fulcrum, the protection member 6 moves in a circular motion as shown in the three-dot chain line in FIG. 1 according to the hinge center 4 when the back door is opened. Instead, the free end side (first
The left side of the figure) protrudes from the cover member 5 in an elliptical motion while slidingly contacting the inner plate 1a of the rear body part 1, and can be rotated without significantly protruding into the interior of the automobile body, allowing the wire harness and washer hose to be rotated. Wiring and piping can be installed to the bank door wiper without exposing it to the outside and looking good.

Claims (1)

[Scope of utility model registration request] This is a structure for wiring wiring to the back door of an automobile, which is attached to the upper part of the rear part of the body with a pivot so that it can be opened and closed up and down. A hole is provided between the two holes, and a protective member that is curved along the rear inner plate of the pivot side head body is disposed between the two holes, and a hole is provided on the outer periphery of the end of the protective member on the bank door side in the same direction as the opening/closing direction of the back door. A fan-shaped recess that expands is provided, and the entire protection member can be rotated independently by the width of the wide end of the fan-shaped recess using the fan-shaped recess as a hole in the inner plate of the back door and using the narrow end of the fan-shaped recess as a fulcrum. The body-side end of the protection member is a free end that can be freely inserted into and removed from the hole in the rear inner plate of the body, and the wiring from the body side to the back door side is inserted through this protection member. Features a structure for wiring wiring to the back door of a car.
