Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to an improvement of an in-vehicle speaker grill which is attached and fixed to an interior part such as a door trim so as to cover an inner side surface of an in-vehicle speaker.

<Prior Art> Normally, an in-vehicle speaker is housed on the back side of an interior component such as a door trim and a rear parcel, and an opening is provided in an interior component located on the front side of the in-vehicle speaker fixed to a vehicle body panel. An in-vehicle speaker grill is attached to the front side of the interior component so as to cover it.

FIG. 3 is a front view showing a speaker grill 2 attached to an automobile door trim 1 as viewed from the inside. The speaker grill 2 has a resin grill base 3 and this grill as shown in FIG. It is composed of a metal net 4 such as a punching metal attached to the front surface side of the base 3, and the peripheral edge of the metal net 4 does not damage the skin material 1a of the door trim 1 as shown in the drawing. It is inserted into the groove portion 5 formed in the base 3 and fixed by welding by electromagnetic induction heating or the like.

<< Problems to be Solved by the Invention >> However, in the conventional speaker grill 2, since it is necessary to form the groove portion 5 for inserting the metal net 4 in the grill base 3, the grill base 3 becomes large,
It has been pointed out that there is a drawback in that the weight of the product is increased and the cost of the material is increased, resulting in an increase in cost.

Furthermore, since the grill base 3 becomes larger, the door trim 1
It has been pointed out that there is a defect that it gives an impression that another component is attached to the product, does not have a sense of unity as a product, and deteriorates the appearance and design.

The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the size of a grill base that supports the outer periphery of a metal net in an in-vehicle speaker grill attached to an interior part such as a door trim. By doing so, it is possible to expect weight reduction and cost reduction,
An object of the present invention is to provide an in-vehicle speaker grill with an improved appearance design of the product.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention provides a speaker opening that is located on the front side of a vehicle-mounted speaker that is housed on the back side of an interior part and that is opened in the interior part. In the in-vehicle speaker grill attached to the surface side of the interior part so as to cover, the in-vehicle speaker grill includes a frame-shaped resin grill base and a metal net attached and fixed to the resin grill base, The resin grill base is composed of a resin molded body having a substantially L-shaped cross section, which has a mounting flange for fixing the outer peripheral edge of the metal net and a vertical wall portion for supporting the inner peripheral surface of the metal net. In addition, a step portion that covers the side wall portion of the mounting flange and gives a sense of unity between the surface of the interior component and the surface of the metal net is formed along the peripheral edge of the opening of the interior component. And wherein the Rukoto.

<Operation> As is apparent from the above configuration, the resin grill base is formed of a resin molded body having a substantially L-shaped cross section including a mounting flange and a vertical wall portion, and has a conventional groove portion. It is possible to reduce the weight and size of the structure.

Further, since the stepped portion is formed at the opening peripheral edge of the interior component so as to cover the mounting flange of the grill base exposed to the outside, the grill base is not exposed to the outside, and the interior component and the metal net are not exposed. A sense of unity can be revealed between.

<< Embodiment >> An embodiment of an in-vehicle speaker grill according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is an overall perspective view showing an in-vehicle speaker grill, a door panel and a door trim according to the present invention, and FIG. 2 is a sectional view showing a state in which the in-vehicle speaker grill is attached to the door trim.

First, referring to FIG. 1, an in-vehicle speaker grill 10 according to the present invention is attached to a door trim 11 so as to cover an opening 12 formed in a door trim 11, and the speaker grill 10 and the opening 12 are located in front of an in-vehicle speaker 13. Located on the side.

The in-vehicle speaker 13 is attached and fixed to the door panel 14 with screws 15.

By the way, the speaker grill 10 is fixed to the surface of the resin grill base 16 and a resin grill base 16 molded in a frame shape by injection molding a synthetic resin such as ABS resin, polyethylene resin, polypropylene resin. It is roughly composed of a metal net 17.

The metal net 17 is punched metal, plain weave wire mesh,
It includes extruding metal, etc.,
It means a thin metal plate having a large number of holes.

Further, the resin grill base 16 is provided with a mounting flange 18 for fixing the outer peripheral edge of the metal net 17 and a vertical wall portion for supporting the inner peripheral surface of the metal net 17, and has a substantially L-shaped cross section. It is composed of a molded body, and the peripheral edge 17a of the metal net 17 is attached and fixed to the upper surface of the attaching flange 18 by electromagnetic induction heating or the like.

Therefore, the resin grill base 16 can be made much smaller and lighter than the conventional grill base, and the material cost can be saved, so that a significant cost reduction can be expected.

Then, as shown in FIG. 2, a speaker grill constituted by attaching and fixing a metal net 17 to a resin grill base 16
In the state where 10 is attached to the door trim 11, as is clear from the drawing, the step portion 19 is formed along the periphery of the opening 12 on the door trim 11 side so as to cover the side wall portion 18a of the attachment flange 18. The resin grill base 16 has this step 19
Thus, the speaker grill 10 and the door trim 11 can be integrated with each other without being exposed to the outside, and the external appearance is improved in design. In particular, if the surface shape of the door trim 11 and the surface shape of the metal net 17 are set so as to give a sense of continuity, the design is further improved.

In order to attach the speaker grill 10 to the door trim 11, the locking piece 20 inserted into the grill base 16 is inserted into the mounting hole 21 provided in the door trim 11 and bent to securely and firmly attach the speaker grill. 10 to door trim 11
Can be installed on.

Further, in the present invention, the ribs 22 are provided at appropriate places on the resin grill base 16 so that the metal net 17 can be easily positioned on the resin grill base 16.

<< Effect of Device >> As described above, the in-vehicle speaker grill according to the present invention has the following special effects.

According to the in-vehicle speaker grill according to the present invention, the resin grill base for supporting and fixing the metal net has only the mounting flange formed along the outer periphery thereof.
Compared to the conventional grill base of the type that forms a groove, it can be made significantly smaller and the weight of the product can be reduced.
This has the effect of significantly reducing the costs associated with material cost savings.

According to the on-vehicle speaker grill according to the present invention, the step portion is formed on the door trim side so as to cover the side wall portion of the flange formed along the outer peripheral edge of the resin grill base when attached to the door trim. The resin grill base is not exposed to the outside, does not give the passenger the impression that another object is attached, and has an effect that the door trim and the speaker grill have a sense of unity and the external appearance is improved.
