PATENTS ACT 1990 COMPLETE SPECIFICATION NAME OF APPLICANT(S):: Shih-Hsiung Li ADDRESS FOR SERVICE: DAVIES COLLISON CAVE Patent Attorneys 1 Nicholson Street,Melbourne, 3000, Australia INVENTION TITLE: Radar sensor for reversing a vehicle and having fine-tuning function The following statement is a full description of this invention, including the best method of performing it known to me/us:- 5102 1. Field of the Invention The invention relates in general to a radar sensor for reversing a vehicle and having a fine-tuning function, and more particularly to a radar sensor for reversing a vehicle, wherein a sensing angle can be finely tuned after installation.
2. Description of the Related Art Advances in radar electronics and increasing awareness in road safety have resulted in the development of radar devices for vehicles such as cars and trucks.
In particular, such vehicles are fitted with radar to assist in reversing the vehicle safely. The radar for reversing the vehicle provides information to a driver to learn whether an obstacle exists behind by transmitting and receiving reflected ultrasonic waves, so as to back up or park the vehicle successfully. Some drivers even fit a video camera at the rear of the vehicle to acquire an optimum understanding of a rear road condition by the video. Both the ultrasonic waves and the video camera feature an accurate sensing range of a sensing component.
Therefore how to complete an accurate setting for a sensing range is an important issue.
However, the conventional radar reversing-assistance products do not provide a function for fine-tuning after installation. Therefore the drivers need to adjust and even refit through trial and error the radar several times to achieve an optimal angle, which is troublesome, disappointing, and even dangerous as a layperson may not achieve the appropriate range.
It is therefore an objective of the present invention to provide a radar sensor P 'OPER\GCN 25)4120 spc Ol8 dm.2V)27 -2for vehicle-reversing and having a fine-tuning function, which can fine-tune a sensing angle after installation of the radar to the vehicle.
According to the present invention there is provided a radar sensor for vehicle reversing and having a fine-tuning function comprising: a base having an exterior surface and defined with a chamber and a component room; the chamber having an inner wall; the component room comprising: a first aperture defined on the exterior surface of the base; and a second aperture defined on the inner wall of the chamber and communicating with the first aperture; a sensor module pivotally held in the chamber; a packing block mounted in the second aperture to abut against the sensor module; a brake mounted in the component room and abutting the packing block; an adjustment element mounted in the component room and connected to the brake to adjust the brake for securing the sensor module in a desired position.
In this way, when the above-mentioned radar sensor is fitted at a rear of a vehicle, the pivoting of the sensor module relative to the base can be used to fine-tune an angle of the sensor module. After tuning to an appropriate angle, the adjustment part can be operated through the exterior surface of the base, so as to control a movement of the brake.
Thereby the brake pushes the packing block upwards, so that the sensor module is secured at a desired position inside the chamber of the base. Therefore, even if the abovementioned car-reversing radar sensor has been installed on the car, the special-designed structure on the sensor still permits convenient fine-tuning of the angle of the sensor.
P IOPEI'CCPI I 2 p1 (1058 dX.21)l2i(X7 -3- In the specification the expression "radar" should be construed broadly enough to include ultrasonic detection.
FIG. 1 is a perspective view of an assembled radar sensor with fine tuning function in accordance with the present invention.
FIG. 2 is an exploded perspective view of the radar sensor in Fig. 1.
FIG. 3 is a side view in partial cross section of the radar sensor of Fig. 1, in an unlocked mode.
FIG. 4 is a front view of the radar sensor of Fig. 1, in a first setting.
FIG. 5 is another front view of the radar sensor of Fig. 1 in a second setting.
FIG. 6 is an end view of the radar sensor showing a first setting in phantom lines and a second setting in solid lines.
FIG. 7 is a side view in partial cross section of the radar sensor of Fig. 1, in a locked mode.
Referring to FIG. 1, a radar sensor for vehicle reversing includes a base 10 and a sensor module 20 with a truncated spherical body. The sensor module 20 permits change of a sensing angle with a super wide-angle manner within the base 10, and also can be locked by an adjustment part installed at an exterior surface of the base 10, which is not shown in the diagram, so as to facilitate fine-tuning of an angle after installation of the radar sensor. The following description provides a detailed embodiment structure regarding to an example of a preferred embodiment of the present invention.
Referring to FIG. 2, a preferred embodiment of the present invention includes the base 10 having a front housing 11 and an back housing 12 combinable to form the base A corresponding first circular opening 111 and a corresponding second circular opening 121 are formed on the front housing 11 1 and the back housing 12 respectively. The first circular opening 111 has an arcuate periphery and the second opening 121 has an arcuate periphery the mirror image of the first circular periphery 111 such that when the front and back housings 11,12 are combined, a truncated spherical chamber is defined to matingly receive therein the truncated sphere of the sensor module 20. Moreover, the front housing 11 and the back housing 12 respectively define two first slots 112 and two second slots 122 on opposed sides of lateral walls. Each slot 112,122 has an open end such that when the housings 11,12 are combined, the open ends of first slots 112 respectively align with the open ends of the second slots 122 to define two corridors which respectively receive pivot stubs 22 protruding from diametrically opposed points of the sensor module Referring to FIG. 3, a top right corner of the first housing 11 and a corresponding top left corner of the second housing 12 define a space respectively, so as to form a component room 13 when the housings 11,12 are combined. The component room 13 includes a first aperture 131 and a second aperture 132 perpendicular to the first aperture 131 .The first aperture 131 has an exit leading out to the end face of the first housing 11. The second aperture 132 has an exit leading to the arcuate periphery of the first housing 11, and includes a packing block 15. An adjustment part 14 is configured at the second aperture 132.
In this preferred embodiment, the adjustment part 14 is a screw.
Further, a brake 30 is configured inside the component room 13. The brake includes a frame 31 for a brake shoe 32 to slide backward and forward on the frame. The frame 31 forms a hole 311 on a lateral wall opposite to the first aperture 131, and brake shoe 32 has a hole 321 that is parallel to a long side of the I brake shoe 32 and corresponding to the hole 311 of the frame 31. The brake shoe 32 includes a breach at an end, and the breach includes a notch 33 having a screw hole, which is corresponding to the hole 321 of the brake shoe 32. In this way, the adjustment part 14 inside the first aperture 131 can go through the hole 311 and the hole 321 of the frame 31 and the brake shoe 32 in sequence, so as to connect with the notch 33 by a screw connection manner. The brake shoe 32 has an inclined wall 322 opposite to a lateral wall of the second aperture 132. When the adjustment part 14 is rotation and counter rotation respectively causing the brake shoe 32 to move forward and backward, so that the brake shoe 32 can push the packing block 15 inside the round chamber.
Still referring to FIG. 2 and FIG. 3, the sensor module 20 includes the sensor installed inside a body, wherein the body includes the truncated sphere 21 for mating with the chamber of the base 10. The stubs 22 provide a range of pivot of the sensor and truncated sphere 21. Moreover, the sensor module 20 includes a sensing terminal 23. The sensing terminal 23 protrudes beyond the first opening 111 of the front housing 11. A sensor component is installed inside the sensing terminal 23. The sensor component can be an ultrasonic transmitter/receiver or an image capture component, and the like.
After each of the above-mentioned components is combined, the example of the preferred embodiment of the present invention is shown as FIG. 1 and FIG.3.
Before the sensor of the present invention is installed, the adjustment part 14 remains motionless in the beginning. The movement block 23 is located at the inner side of the component rooml3, which does not push the packing block At this moment, the packing block 15 is located inside the second opening 132.
After the complete installation of the sensor, the angle of the sensor module can be adjusted. Since the packing block 15 is not yet operational, the truncated sphere 21 of the sensor module 20 and the chamber of the base 10 are not secured immovably to each other, so that the sensor module 20 can be moved liberally.
FIG. 4, FIG. 5 and FIG.6 illustrate variations of movement of the truncated sphere 21 relative to the base 10. After performing adjustments to a fix position, the adjustment part 14 installed on the external surface of the front housing 11 inside the first opening 131 can be moved around. At this moment, the movement block 32 inside the component room 13 is pushed forward, so that the shoe 32 pushes the packing block 15 upwards inside the second aperture 132, as shown in FIG.7.
The packing block 15 thus engagingly abuts the truncated sphere 21 of the sensing module 20. Thereby the sensing scope is well tuned and locked.
In conclusion, the present invention contributes to the radar sensor having a fine-tuning function whereby a pantoscopic angle and direction of the sensor module can be adjusted. The base further includes a brake to work in coordination with the adjustment part, which is an external control of the base, so as to lock the sensor module at the adjusted angle and direction. Since an operation location of a lock mechanism is at the exterior of the base, the angle of the sensing sensor can be conveniently fine tuned after installation to make the sensing range accurate.
