Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to an automobile lid that can be easily coated with rust-preventing oil to improve the rust-preventing effect.

(Prior art) In general, automobile lids are
As disclosed in Japanese Patent No. 34987, it consists of an outer panel and an inner panel, and the peripheral edges thereof are hemmed to join them together. A plurality of relatively large openings are formed in the inner panel to reduce weight.

For example, if the above-mentioned lid is a bonnet that opens and closes the engine room, rainwater splashed up from the road surface when driving in the rain or washing water when washing the car will be absorbed by the bonnet tip, which is curved forward and downward from the opening in the inner panel. There is a risk that the rust may penetrate into the inner surface of the hemming section on the side and cause rust on the inner surface of the hemming section and its vicinity.

In order to prevent the above-mentioned rust from occurring, anti-rust oil is applied to the inner surface of the hemming part and its vicinity, but the anti-rust oil is applied by inserting the anti-rust oil application nozzle through the opening in the inner panel. Therefore, it is difficult to uniformly apply the coating to the inner surface of the hemming part, which is formed over the entire length of the bonnet in the width direction, and its vicinity, resulting in uncoated or incompletely coated areas. There is a problem that the rust prevention effect is small.

(Purpose of the invention) This invention was made in order to solve the above-mentioned conventional problems, and it is possible to uniformly apply rust-preventing oil over the entire length of the inner surface of the hemming part of the lid and its vicinity. The object is to provide an automobile lid with improved effectiveness.

(Structure of the device) In this device, a nozzle insertion hole is formed in the vertical wall surface of the side inner panel near one end in the longitudinal direction of a lid consisting of an outer panel and an inner panel. A guide groove is formed, and the nozzle insertion hole and the guide groove communicate with each other, so that the antirust oil coating nozzle can be inserted through the nozzle insertion hole and moved in the width direction along the guide groove to apply the antirust oil. It is done like this.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a lid to which this invention is applied, and this embodiment shows a bonnet with an open end on the front end and which can be opened and closed up and down. In the same figure, the bonnet 1 is composed of an outer panel 1A and an inner panel 1B as in the conventional case, and a hemming part 2 similar to the front downwardly curved tip side shown in FIG. By forming them, both 1A and 1B are integrally coupled. A nozzle insertion hole 3 (see FIG. 1) is opened in the vertical wall surface 1b of the side inner panel 1B near the tip of the lid 1. As shown in FIG.

In FIG. 2, the tip side of the inner panel 1B,
That is, a guide groove 4 having a semicircular cross section is formed in the upper rear side of the hemming part 2 along the entire length of the inner panel 1B in the vehicle body width direction, and this guide groove 4 is formed to communicate with the nozzle insertion hole 3. . That is, the center of the nozzle insertion hole 3 and the center of curvature of the guide groove 4 are set concentrically.

Reference numeral 5 denotes a stiffener, and when the bonnet 1 is opened forward as in this embodiment, when the bonnet 1 is locked from the open state, the tip side of the bonnet 1 is strongly tightened just before locking. Since it is pressed down, it serves as a reinforcing member to prevent the bonnet 1 from being distorted by this pressing force. Therefore,
When the bonnet 1 is rear-opening, the stiffener 5 may not be provided on the tip side of the bonnet 1.

A guide piece 5a is formed at the tip of the stiffener 5 and is curved upward with a curvature substantially equal to the curvature of the guide groove 4.

In the above configuration, when applying rust preventive oil,
Insert the anti-rust oil application nozzle 6 shown in Fig. 1 from the nozzle insertion hole 3, and while moving it along the guide groove 4 in the width direction of the vehicle body, place it on the rod 7 to which the anti-rust oil application nozzle 6 is attached. By operating the switch (not shown), the rust preventive oil 8
It is done by blowing out, and by this,
Rust preventive oil 8 is applied to the inner surface of the hemming portion 2 and its vicinity.

Although the above embodiment uses the bonnet 1 as the lid, it is not limited to the bonnet 1, and can of course be applied to a trunk lid that opens and closes the trunk room and a back door that opens and closes the rear opening of the vehicle body. . When applied to these trunk lids and back doors,
A nozzle insertion hole 3 and a guide groove are provided on the rear end side of the trunk lid or back door.

(Effects of the invention) As explained above, according to this invention, the anti-rust oil application nozzle is inserted through the nozzle insertion hole opened in the vertical wall of the inner panel, and the anti-rust oil application nozzle is inserted along the guide groove communicating with the nozzle insertion hole. Since the lid can be moved in the width direction of the vehicle body, the rust preventive oil can be uniformly applied over the entire length of the inner surface of the hemming portion of the lid and its vicinity, improving the rust preventive effect.
