JPH09281222A - Fixing structure of ultrasonic sensor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate operation for boring a dedicated hole for fixing and to greatly improve the design by building the sensor in an accessory such as an emblem installed at the outer peripehral part of a vehicle and forming it in one body. SOLUTION: The ultrasonic sensor 1 of a vehicle obstacle detecting device is built in the emblem 7 and formed in one body. In this case, the lead wire 8 of the sensor 1 is passed through a fixing hole 9 which also positions the emblem 7 and connected to a controller 10 in a cabin. Thus, the need for boring a hole so as to fix the sensor 1 to the vehicle is eliminated and the sensor 1 is made inconspicuous after being fixed to greatly improve the design.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting an ultrasonic sensor in an obstacle detecting device for a vehicle which detects an obstacle around the vehicle by using ultrasonic waves and notifies the driver of the obstacle.

[0002]

2. Description of the Related Art As shown in FIG. 4, an ultrasonic sensor of a conventional vehicle obstacle detection device comprises an ultrasonic sensor 1 and a sensor housing 2 which supports the ultrasonic sensor 1 and is mounted on a vehicle. It is a dedicated ultrasonic sensor unit 3 mainly configured. In order to mount the ultrasonic sensor unit 3 thus configured on a vehicle, a method is used in which a mounting hole 5 is opened in the bumper 4 and the ultrasonic sensor unit 3 is fixed with a fitting nut 6 or the like.

[0003]

However, in order to mount an ultrasonic sensor unit of the type in which a conventional ultrasonic sensor is housed in a dedicated housing, it is necessary to make a new mounting hole in a bumper or the like. . However, since this type of device is an object to be installed according to the user's request, it is usually necessary to perform hole drilling in a post-process after vehicle manufacturing, and the workability and installability of hole drilling are poor, and the installation time and Not only is the installation cost very high, but also the ultrasonic sensor unit attached to the bumper becomes noticeable even after the installation, and there is a problem that the appearance is poor and the design is impaired.

The present invention has been made to solve the above problems, and eliminates the work of making a dedicated hole for mounting an ultrasonic sensor on a vehicle, and makes the ultrasonic sensor inconspicuous after mounting. An object of the present invention is to provide a mounting structure for an ultrasonic sensor that can significantly improve the design.

[0005]

SUMMARY OF THE INVENTION An ultrasonic sensor according to the present invention is an equipment for mounting various ultrasonic sensors on the outer peripheral portion of a vehicle, that is, an emblem or a lamp indicating a manufacturer's mark, vehicle type, grade, displacement, etc. Kind, bumper, radiator grill, grill guard, number frame, malls,
It is a means for solving the problem by being built in a mirror or the like and integrally formed.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an embodiment showing a mounting structure of an ultrasonic sensor in which an ultrasonic sensor 1 in an obstacle detection device for a vehicle according to the present invention is incorporated into an emblem 7 and integrally formed. FIG. 2 is a cross-sectional view showing the mounting state, in which the lead wire 8 of the ultrasonic sensor 1 formed integrally with the emblem 7 is provided.
Is connected to a controller 10 in the vehicle through a mounting hole 9 that also functions as a positioning for the emblem 7.

Although FIG. 1 shows an embodiment in which one ultrasonic sensor 1 is integrally formed on the emblem, a plurality of ultrasonic sensors 1 are integrally molded at the same time to expand the detection range of obstacles. You can also Further, FIG. 3 is a view showing an embodiment in which the ultrasonic sensor 1 is also integrally formed on the lamp 11.

[0008]

EFFECTS OF THE INVENTION The ultrasonic sensor mounting structure thus configured eliminates the work of forming a dedicated hole for mounting the ultrasonic sensor on a vehicle, and makes the ultrasonic sensor inconspicuous after mounting. It has the effect of significantly improving the sex, and its practical effect is great.
