Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for mounting various types of resin panels to other articles, and more particularly, to a long panel made of a synthetic resin material which is liable to expand or contract due to a temperature change. The present invention relates to a resin panel mounting structure capable of maintaining a stable mounting state of a molded body, for example, a cowl top cover while allowing a change in its form.

[0002]

2. Description of the Related Art As the above-mentioned resin panel, there is, for example, a cowl top cover which is mounted so as to seal between a lower end of a front windshield of a vehicle body and a front hood. In general, the cowl top cover is formed by connecting a single long panel having the width of the vehicle or a half of a panel divided into two. The cowl top cover is fixed to the cowl top portion of the vehicle body using an appropriate attachment means, and rainwater and dust enter when outside air is introduced into the vehicle from an air intake formed in the cowl top portion of the vehicle. And improves the aesthetics of the lower end of the front windshield of the vehicle.

A structure for mounting such a cowl top cover on a vehicle body is disclosed in Japanese Patent Application Laid-Open No. Hei 7-10037. The cowl top cover disclosed in the publication has a clip projecting from the back surface of the main body. The clip is composed of a small plate piece having a substantially hexagonal overall shape, a front portion having an arrow shape, and a covering portion made of a soft material covering the peripheral surface except for the front and back surfaces of the concentric portion. Have.
The core portion is made of the same hard synthetic resin material as the cowl top cover body, and is integrally formed at the same time as the cowl top cover body, and the covering portion made of a soft synthetic resin material is entirely formed on the core portion by two-color molding. Are formed and integrated so that the front shape of each of them is substantially a pentagon. On the other hand, in the cowl top portion to which the cowl top cover is attached, a mounting hole having the same shape slightly smaller than the cross-sectional shape of the base of the clip is formed at a position corresponding to the clip.

[0004] The cowl top cover is attached to the vehicle body by fitting its clip into the attachment hole. At this time, the clip has a coating portion made of a soft resin on the outer periphery thereof, so that the clip is tightly engaged with the mounting hole by the elastic force of the coating portion without any gap.

[0005]

However, in general, the cowl top cover is formed of a synthetic resin such as polypropylene or ABS (acrylonitrile-butadiene-styrene resin) which easily expands and contracts due to a temperature change. Furthermore, since the cowl top cover is a long panel molded body having a length equal to or half the width of the vehicle, the degree of expansion and contraction particularly in the vehicle width direction increases due to a change in ambient temperature.

[0006] In this case, the cowl top cover disclosed in the above-mentioned publication has a clip formed integrally with the cowl top cover main body, which is tightly attached to the mounting hole of the cowl top portion without any gap, so that the cowl top cover and the cowl top can be closed. For example, if the cowl top cover expands, the cowl top cover rises at the part other than the fixed part, which impairs the appearance and the front windshield and the front hood. The sealing function may be impaired. Alternatively, when the cowl top cover contracts, the clip may easily come off from the mounting hole, and the cowl top cover may come off the vehicle body.

Further, since the clip is closely attached to the mounting hole due to the elasticity of the covering portion as described above, the core portion is thinned at the contact portion, that is, at the base of the clip to increase the thickness of the covering portion. Must. Therefore, despite the fact that the entire clip has a substantially pentagonal shape, the shape of the core has to be an arrow shape as described above,
Since the core having the complicated shape is formed integrally with the cowl top cover main body, the structure of the molding die becomes complicated, which not only leads to an increase in cost but also complicates the molding operation. Becomes Further, since the covering portion made of a soft material is formed around the core portion by two-color molding, the manufacturing cost of the cowl top cover body is further increased. Further, the clip is merely in close contact with the mounting hole by the elastic deformation of the soft material constituting the covering portion, and is not positively engaged by the engaging portion of the clip with respect to the mounting hole. Therefore, the clip may come off from the mounting hole and the cowl top cover may come off the vehicle body due to severe vibration of the vehicle body or deterioration of the soft resin material due to long-term use.

In view of the above, the present invention is not limited to the case where a long resin panel, such as a cowl top cover of a vehicle body, is attached to an area where the temperature change is large. A mounting structure of a resin panel which is allowed, and is prevented from floating from a mounting portion or detachment of a fixed portion, and can maintain a stable mounting state.
An object of the present invention is to provide a mounting structure for a resin panel that can be easily mounted, has sufficient mounting strength, and can be manufactured at low cost.

[0009]

In order to achieve the above-mentioned object, the present invention relates to a method for fitting an attaching member provided on a resin panel into a mounting hole formed in a member to be mounted, and mounting the resin panel on the member to be mounted. In the mounting structure, the engaging member is formed of an elastic piece having one end fixed to the panel and having an elastic portion bent, and the free end thereof has an inner peripheral surface and a lower surface of a partial periphery of the mounting hole. And a dimension between the outer surface of the fixed end and the outer surface of the free end is set to be shorter than the dimension of inserting the engaging member of the mounting hole. The mounting structure of the resin panel, which is characterized by the above, is the main configuration.

The elastic portion may have any shape as long as the fixed end and the free end of the engaging member can be elastically deformed in a direction approaching each other and can be elastically restored in a direction in which they are separated from each other. For example, the elastic portion may be curved in an arc shape or the elastic portion may be bent, and the elastic piece has a substantially U-shaped cross section, or the elastic piece has a substantially V-shaped cross section.
It is preferable to form a letter.

Preferably, the engaging portion has a substantially L-shape having a vertical portion and a horizontal portion, and the vertical portion extends from the mounting hole in a state where the engaging member is fitted in the mounting hole. The horizontal portion has a length that protrudes, and a dimension between a tip of the horizontal portion and an outer surface of the fixed end is set to be longer than a dimension for inserting the engaging member of the mounting hole. Has a tapered surface.

Further, a rectangular opening is formed in the resin panel, the one end of the fastening member is fixed to one peripheral edge of the opening, and the free end of the fastening member is accommodated in the opening. It is preferable that the other peripheral edge of the opening is set to be longer than the dimension between the inner surface of the fixed end of the engaging member and the tip of the horizontal portion of the engaging portion.

[0013] The engaging member can be formed integrally with the resin panel, or the engaging member can be formed separately from the resin panel, and one end thereof can be fixed to the resin panel. .

Examples of the resin panel include a cowl top cover of a vehicle. The cowl top cover is injection molded from a thermoplastic synthetic resin such as polypropylene or ABS (acrylonitrile-butadiene-styrene resin). In this molding, even when the fastening member is integrally formed with the cowl top cover, the fastening member has a simple shape, and furthermore, a portion where the fastening member is fixed. The opening is formed, especially when the dimension of the other peripheral edge of the opening is set longer than the dimension between the front end of the horizontal portion of the engaging member and the inner surface of the fixed end, It is possible to use a mold whose opening type is simple. Therefore, the cost of the mold can be reduced, and furthermore, the failure of the mold at the time of manufacture is extremely small, the maintenance work is reduced, and the stable operation becomes possible.

In order to mount the cowl top cover employing the above-described mounting structure to the cowl top portion of the vehicle body to be mounted, the position of the mounting hole formed in the cowl top portion and the position of the engagement member of the cowl top cover are set. And press the cowl top cover against the cowl top. At this time, when the opening is formed in the cowl top cover, the position of the engaging member can be easily confirmed by the opening, and the positioning of the engaging member and the mounting hole is facilitated.

The cowl top cover is pressed against the cowl top portion, and the engaging member is inserted into the mounting hole from its elastic portion. At this time, the elastic portion is elastically deformed such that the free end approaches the fixed end, the horizontal portion of the engaging portion passes through the mounting hole, and then the elastic portion elastically returns. As a result, the engaging member fits into the mounting hole. As described above, the fitting operation is extremely easy. However, when the engaging portion formed at the free end of the engaging member has a tapered surface at the insertion end of the horizontal portion, the fitting hole of the attaching hole is not required. The tapered surface comes into contact with the peripheral portion, and the elastic portion is more smoothly deformed.

In this fitted state, the vertical portion of the engaging portion is engaged with the inner peripheral surface of a part of the mounting hole, and the horizontal portion is engaged with the lower surface of the peripheral edge. Since the engaging member of the cover is securely fitted in the mounting hole, even when the vehicle body vibrates, the engaging member does not come off from the mounting hole and a stable mounting state can be maintained.

Further, in the engaging member, a dimension between an outer surface of the fixed end and an outer surface of the free end is set shorter than an inserting dimension of the attaching member in the mounting hole. The attachment member is made of an elastic piece, and its free end is elastically deformable toward the fixed end, so that the cowl top cover is slightly attached to the cowl top portion in the vehicle width direction even after being attached to the cowl top portion. It is possible to move. For this reason, the cowl top cover is allowed to expand and contract due to a change in ambient temperature, does not rise or fall off the cowl top portion, can maintain a stable mounting state and appearance, and does not impair the sealing function. .
