Description

[Detailed description of the invention] (Field of industrial application) This invention is applicable to the installation of vehicle sensors (e.g., water droplet sensor that detects water droplets adhering to the windshield, light sensor that detects the amount of light from the front, etc.). It's about structure.

(Prior art) In recent years, electrical components of automobiles (for example, wipers,
Demand from customers to automatically turn on and off air conditioners, headlights, etc. is increasing significantly, but in order to automatically turn on and off these electrical components, sensors that detect the timing and conditions of turning on and off are needed. is required. Examples of such sensors include a water drop sensor that detects water droplets adhering to the windshield, a light sensor that detects the amount of light from the front, and a vibration sensor that detects the sound of rain and the vibrations of rain hitting the vehicle body. Where on the vehicle body it should be installed is an important issue from the viewpoint of the driver's forward visibility and the external appearance. As a conventionally known sensor for a vehicle, a sensor has already been proposed in which a water droplet sensor is attached directly to the inner surface of a front windshield, as described in Japanese Patent Application Laid-Open No. 58-84141.

(Problems to be solved by the invention) When installing a water drop sensor alone on the inner surface of the windshield as in the above-mentioned known example, depending on the mounting location, the water drop sensor alone may be exposed.
Furthermore, it becomes difficult to wire the lead wires connected to the water droplet sensor, resulting in a problem of poor appearance.

This invention was made in view of the above points,
It is an object of the present invention to provide a mounting structure for a vehicle sensor that does not obstruct a driver's forward view and does not cause a risk of deterioration in appearance.

(Means for Solving the Problems) In the present invention, as a means for solving the above problems, a room mirror is installed in an overhead console provided on the roof of the vehicle interior and equipped with electrical components connected to a roof harness. At the front of the installation site,
An extension part extending to the top of the front windshield is provided, and a mounting hole for arranging a sensor disposed opposite to the front windshield and a lead wire connected to the sensor are arranged in the extension part. a lead wire arrangement section for connecting the sensor and the lead wire to the extension section and the overhead console to connect the sensor and the lead wire to the roof harness; A lid is attached to cover it.

(Function) In the present invention, the following effects can be obtained by the above means.

In other words, a sensor placed opposite to the inner surface of the front windshield directly detects obstacles to forward visibility (for example, raindrops, snowflakes, etc. attached to the outer surface of the windshield), and electrical components automatically operate based on the detection signal. Since the on-off and on-off operations are controlled in a consistent manner, malfunctions are almost eliminated. Furthermore, since the sensor is disposed in an extension extending from the overhead console in front of the rearview mirror, and the lead wires are also routed within the extension and the overhead console, the driver's forward view is not obstructed. This also improves the appearance. Furthermore, since the sensor is mounted in a mounting hole provided in the overhead console extension, there is no need for the operator to set the location where the sensor will be installed. Furthermore, the extension part is located away from the rearview mirror, and the sensor and lead wire can be assembled with the lid removed.
Assembling workability is improved. The lead wires will be connected to the roof harness together with the electrical component lead wires inside the overhead console.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

In this embodiment, in the overhead console 3 provided on the roof 2 of the vehicle interior 1, an extension part 6 that extends to the top of the front windshield 5 is integrally provided at the front part of the mounting area of the rear-view mirror 4. has been done. A room light 7 and a switch 8 for the room light are provided at a substantially central portion of the overhead console 3 in the vehicle width direction (that is, the mounting portion of the room mirror 4).

A sensor 9 is disposed within the extension portion 6 and is arranged to face the front windshield 5 . The sensor 9 is a capacitance type sensor that directly detects obstacles to front visibility (for example, raindrops, snowflakes, etc. attached to the outer surface of the windshield), and is housed in a resin case. installed.

As shown in FIG. 2, the sensor 9 is mounted by fitting into a mounting hole 10 formed in the overhead console extension 6 and securing it with screw screws 11, 11. Further, a lead wire 12 connected to the sensor 9 is housed and wired in a lead wire arrangement portion 13 formed in the extension portion 6 so as to be continuous with the mounting hole 10 .
After the sensor 9 is housed in the mounting hole 10 and the lead wire 12 is housed in the lead wire placement part 13, the extension part 6 is removably covered with a cover 14 that covers them. Note that the lead wire 12
is wired to the lead wire arrangement portion 13 of the extension portion 6, and then wired to the roof harness together with the lead wires of the room light 7, etc. within the overhead console 3.

In the drawings, reference numeral 15 is a roof panel, 16 is a front header, and 17 is a trim.

With the above configuration, the sensor 9 is installed in the overhead console extension 6 in front of the rearview mirror 4, which not only eliminates the risk of obstructing the driver's forward view, but also improves the appearance. is also extremely good. Also, sensor 9
are arranged opposite to the inner surface of the front windshield 5, so that forward visibility obstacles (for example, raindrops, snowflakes, etc.) adhering to the outer surface of the front windshield 5 can be directly detected.
Compared to conventional methods that detect vibration or sound,
There is almost no risk of malfunction.

Furthermore, since the sensor 9 is installed in the mounting hole 10 provided in the overhead console extension 6, there is no need for the operator to set the installation location of the sensor 9, which simplifies the sensor installation work. At the same time, it is not necessary to make the lead wire 12 longer than necessary. Furthermore, the extension part 6
is located away from the rearview mirror 4, and the sensor 9 and lead wire 12 can be assembled with the lid 14 removed, resulting in extremely good assembly workability. Note that the lead wire 12 is connected to the roof harness together with the lead wires for electrical components in the overhead console 3, which greatly contributes to improving work efficiency.

It goes without saying that the present invention is not limited to the illustrated embodiment, and that the design can be modified as appropriate without departing from the gist of the invention.

(Effects of the invention) As described above, according to the invention, a sensor is disposed in the overhead console extension in front of the rearview mirror, and a lead wire connected to the sensor is provided in the extension and the overhead console. Since it is wired, it does not obstruct the driver's forward view and has the practical effect of providing an extremely good external appearance.

In addition, since the sensor is arranged opposite to the inner surface of the front windshield, obstacles to forward visibility (i.e., raindrops,
Snowflakes, etc.) are detected directly, and electrical components are automatically controlled to start and stop based on the detection signal.
In addition to eliminating malfunctions compared to conventional devices that detect vibration or sound, it also eliminates the possibility of malfunctions or decreases in detection accuracy caused by insects in the room or dirt on the inside of the glass. be.

Furthermore, since the sensor is installed in the mounting hole provided in the overhead console extension, there is no need for the operator to set the sensor installation location, which simplifies the sensor installation process. This also has the effect of eliminating the need to make it longer than necessary.

Furthermore, since the extension is located away from the rearview mirror and the sensor and lead wires can be assembled with the lid removed, the assembly workability is extremely improved.

Furthermore, since the lead wires are connected to the roof harness together with the electrical component lead wires in the overhead console, there is also the effect of greatly contributing to improving work efficiency.
