The seat plate has a hole through which a plastic stud is inserted. A relatively large circular hole is made in the bumper of the automobile and relatively small holes are formed on both sides of the bumper. The ultrasonic radiation end is applied to the circular hole from the inside of the bumper, and a stud bolt is passed through the small hole. A seat plate is applied to the rear surface of the sensor sandwiched between these bolts, and a bolt is passed through the hole of this seat plate and tightened with a nut to attach the sensor to the bumper.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention is intended to alert a driver when an obstacle is outside the driver's field of view of a vehicle, or to alert a person when there is a person other than the obstacle outside the driver's field of view. It relates to a fixture for a detection sensor.

[0002]

[Prior art]

 An out-of-field obstacle detection sensor is widely used to detect a short-distance obstacle with an ultrasonic sensor and alert the driver when the vehicle moves backwards, enters a garage, or travels in a narrow passage. There is. This sensor is usually a cylinder and is fixed to a bumper of an automobile, for example, by using a fixture. First, a circular hole for allowing the bumper to radiate ultrasonic energy from the sensing sensor and a small hole for preventing the cylindrical body from rotating are formed. Insert the rotation stop protrusion of the cylinder into the small hole, project the ultrasonic wave emission end of the cylinder from the inside of the bumper, and insert the U-shaped fixing ring from the outside of the bumper into the groove around the emission end. . Next, pass the tapping screw through the holes of both legs of the U-shaped fixing ring and screw it into the bumper to fix the fixing ring to the bumper, and thereby to fix the sensing sensor to the bumper. Finally, cover the fixing ring with a plastic decorative plate with a circular hole in the center to finish. This installation work is complicated and therefore reduces the efficiency of the assembly line flow work, and it is not easy for an individual to install a detection sensor after purchasing a car.

[Problems to be solved by the invention]

 The problem to be solved is the complexity of the installation of the sensor for detecting obstacles outside the visual field, resulting in the inefficiency of the installation work and the difficulty of the work by the individual.

[0004]

[Means for Solving the Problems]

 According to the present invention, a flat fixing plastic plate, a seat plate, and two nuts constitute an out-of-field obstacle detection sensor attachment. A hole is provided on the plastic plate to allow the radiant energy from the out-of-field obstacle detection sensor to pass through. It is separated from the width of the detection sensor in the horizontal direction and is longer than the length of the detection sensor on both sides of the hole. Plant the two bolts together with the plastic plate. This part can be integrally molded in a plastic mold at low cost.

The seat plate has holes through which the bolts pass at intervals equal to the distance between the two plastic studs. This seat plate may be made of metal or plastic if it has appropriate rigidity. Install a sensor on the bumper of the car to make a circular hole to radiate ultrasonic energy from the sensor and small holes on both sides. The ultrasonic wave emitting end of the cylinder is applied from the inside of the bumper, an implant bolt is passed through the small hole, and a seat plate is applied to the rear surface of the sensing sensor sandwiched between these bolts. Pass the bolt through the hole in this seat and tighten the nut to attach the sensor to the bumper.

【Example】

An embodiment of the present invention will be described with reference to FIG. The out-of-field obstacle detection sensor mounting device 1 comprises a flat fixing plastic plate 2, a seat plate 5, and two nuts 7 ₁ and 7 ₂ as a whole. The plastic plate 2 is provided with a hole 4 through which the radiant energy from the out-of-field obstacle detection sensor 11, for example, ultrasonic energy is passed, and is separated from the lateral width of the detection sensor 11 on both sides of the hole 4, respectively. Two bolts 3 ₁ , 3 ₂ longer than the longitudinal length of the detection sensor 11 are planted integrally with the plastic plate 2. This member is integrally molded by plastic molding.

The seat plate 5 has holes 6 ₁ and 6 ₂ through which the bolts are inserted at an interval equal to the interval between the two plastic studs 3 ₁ and 3 ₂ . A circular hole 10 for emitting ultrasonic energy from the detection sensor 11 and small holes 9 ₁ , 9 ₂ are formed on both sides of the circular bump 10 of the automobile bumper 8 to which the detection sensor 11 is attached. The ultrasonic wave emitting end of the cylindrical body 11 is applied to the inside of the bumper 8 and the studs 3 ₁ and 3 ₂ are passed through the small holes 9 ₁ and 9 _2, and the rear surface of the detection sensor 11 sandwiched between these bolts. Apply the seat plate 5. The detection sensor 11 is attached to the bumper 8 by inserting the studs 3 ₁ and 3 ₂ into the holes 6 ₁ and 6 ₂ of the seat plate 5 and tightening the nuts 7 ₁ and 7 ₂ . The surface of the plastic plate 2 may be decorated to form a decorative plate.

[0008]

[Effect of the invention]

 As described above, according to the present invention, the mounting of the detection sensor is facilitated, which improves the workability, and also when the detection sensor is purchased by an individual for the first time, it is easily mounted on the vehicle. And the detection sensor can be attached without fail. Further, as compared with the conventional fixture, the main part thereof can be integrally molded of plastic, so that the manufacturing cost can be reduced.
