Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle meter device installed in an externally exposed state, and more particularly, to a vehicle meter equipped with a flexible printed circuit on a motorcycle or snowmobile. Regarding the device.

[0002]

2. Description of the Related Art Generally, a flexible printed circuit board (hereinafter referred to as "FPC") that outputs a predetermined operation information signal to a meter body by a pulse signal or the like according to a measurement amount of a detecting portion.
Has a structure in which a predetermined conductive path is formed of a conductive material on a flexible material, and is fixedly mounted on the back surface of the meter body or the like. And, in the traveling vehicle meter device using this FPC,
Since it is necessary to keep waterproofness at the PC and the connecting portion between the FPC and the meter body, the FPC and the meter body have a case body 50 as shown in FIG. 5 (a side view of a conventional traveling vehicle meter device). It is housed inside and installed in place.

More specifically, as shown in FIG. 6 (longitudinal sectional view of FIG. 5), the meter main body 51 has the above-mentioned FPC 52 fixed to the back surface (left side in FIG. 6). Further, a mounting bracket 53 for mounting the meter body 51 at a predetermined position of a traveling vehicle or the like (not shown) is attached to the rear surface of the meter body 51 to which the FPC 52 is fixed. A part of the mounting bracket 53 has two protruding portions 51A protruding from the rear surface of the meter body 51.
It is attached to 51A via a vibration-proof cushion 54.

The meter body 51 and the FPC 52
Is accommodated in the case body 50 together with a part of the mounting bracket 53. Specifically, the case main body 50 is formed of an upper case 50B and a lower case 50A as shown in FIG. Of these, the upper case 50B covers the meter main body 51 from the front side (the right side shown in FIG. 6) of the meter main body 51, and the lower case 50A is the back side of the meter main body 51, that is, the mounting bracket 53.
It is formed and mounted so as to face the upper case 50B from the mounting side and fit into the opening of the upper case 50B.

Further, a waterproof packing or the like (not shown) is attached to the fitting portion 50C between the upper case 50B and the lower case 50A. Also, the upper case 5
A waterproof cushion 57 is provided at a fitting portion between the 0B and the lower case 50A, and at a portion where the above-described mounting bracket 53 penetrates the case main body 50 and is exposed to the outside, that is, a portion 56 shown in FIG. It is installed. The waterproof cushion 57 is provided to prevent water or the like from entering the case body 50 from the portion 56 where the fitting 53 penetrates the case body 50 and is exposed to the outside.
3 is mounted between the upper case 50B and the lower case 50A. Here, reference numeral 58 shown in FIG. 6 is an FPC.
Reference numeral 57 designates a lead wire connected to the lead wire 52.
8 is a waterproof packing mounted between the lower case 50A and the reference numeral 59 is a connecting coupler for connecting the FPC 52 and the lead wire 58.

[0006]

In the above-mentioned conventional example,
In order to keep the inside of the case waterproof, a waterproof cushion is attached between the mounting bracket and the upper and lower cases. For this reason, the case main body is supported in a state in which the mounting bracket is in contact with the waterproof cushion portion and the two protruding portions protruding from the back surface portion of the meter main body. Therefore, the vibration generated in the traveling vehicle is directly transmitted to the case body not only from the above-mentioned two protruding portions but also from the waterproof cushion portion, and the resonance point at the time of design shifts by that amount. There is an inconvenience that the floating state between the metal fitting and the case body is lowered. Further, if left unattended, the influence of vibrations from the traveling vehicle and the like transmitted to the case body becomes excessive, and in such a case, there is a disadvantage that the durability of the entire apparatus is reduced.

Further, the waterproofness of the above-mentioned waterproof cushion is not always perfect, and there is a disadvantage that water or the like easily enters the meter device depending on the use environment.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a meter device for a traveling vehicle, which is capable of improving the disadvantages of the prior art and, in particular, increasing the durability of the entire device and improving the waterproof property of the device. That is the purpose.

[0009]

According to the present invention, a meter body, a flexible printed circuit that outputs a predetermined information signal to the meter body, and a case body that houses the flexible printed circuit and the meter body. Is equipped with. Then, a mounting bracket is provided on the back surface of the case body. This is trying to achieve the previously mentioned objectives.

[0010]

Since the inside of the case body is kept waterproof, a waterproof cushion between the mounting bracket and the case body as in the conventional example is not required. Therefore, for example, the vibration generated in the traveling vehicle or the like is transmitted to the case body only from the two protrusions on the back surface of the case body, and the resonance point at the time of design does not shift. Further, the case body is not provided with a portion through which the mounting metal fitting penetrates outward from the inside of the case body and is exposed to the outside. Therefore, no waterproof measure is required between the mounting bracket and the case body.
