Fig. 11 is a schematic diagram showing the effective sensing range of the system of Fig. 10.
Now referring to Fig. 1 thru 4, the automatic alarm system 01 of the present invention comprises a casing 1, a motor 2 retained within the casing 1, a reduction gear box 3, a revolving disc 4, a supersonic transmitter 5, a supersonic receiver 6, a printed circuit7 and a sound/light alarm 8.
The casing 1 is divided into two sections, both of cylindrical shape, however, the diameter of the upper section 1 a is greater than that of the lower section 1b. The revolving disc4, supersonic transmitter 5, receiver 6 and printed circuit 7 are retained in the upper section 1a. An opening 11 extends through half of the circle at the front of upper section 1 a. Said opening 11 having its upper and lower edge provided with semicircular guide channels 12-12. At the back of the casing 1, a pair of mounting flanges 14-14 having slots 13-13 are projected at both sides.
The lower section 1b of the casing lisa sealed chamber, a motor2 is vertically mounted therein, with a supporting member 21 and having the motor shaft 22 standing upright.
Above the motor 2, a gear box 3 with a train of redu ct gea r 31 is connected to the motor shaft 22.
Said output shaft 32 of said gear train 31 projects upwardly th rough a center opening of the printed circuit plate 7 along the center line of said upper section 1a of the casing 1. Said revolving disc4 is mounted to the top end of the output shaft 32, so that when the motor 2 starts rotating, the disc 4 rotates at a predetermined speed through reduction geartrain 31.
Said revolving disc4 having a circular vertical wall 42 serving as dust cover extends from a funnel shaped opening 41 toward both sides along the periphery of the disc 4. A vertical plate 43 is provided at the Center of the funnel shaped opening 41 for the mounting of said supersonic transmitter 5 and receiver 6.
The upper edge 44 of said dust cover 42 with a peripheral length greater than that of said guide channel 12 is slidably inserted into the upperchan- nel while the corresponding lower edge 45 like wisely into the lower channel 12. When said funnel shaped opening 41 is placed at front center of the casing opening 11, upper and lower edges 44,45 still remain in the channels 12, 12 to assure a smooth rotation.
In Fig. 4, it can be seen that through the floor of disc 4, electric terminals 46 and 47 are disposed respectively at a different radial distance r1 r2 from the center of the disc. Input terminals 5a, 6a of the transmitter 5 and receiver 6 are connected via conduct wire I to the respective upper end of terminals 46 and 47. The lower ends of terminals 46 and 47 are getting into contact with the respective upper surface of the two arc shaped conductor plates 71,72 disposed upon said printed circuit plate 7 under said disc4 between the upper section la and the lower section 1 b of the casing I via whatever spring means 46a, 47a. As for the output ends of said transmitter 5 and receiver 6 are grounded via lead wire 1 to the center shaft 32 of the disc 4.Said printed circuit plate 7 is a round disc with a recess 73 formed at the rear
part and is fixed within said casing 1 with suitable
means such as screw 74. Two conductor plates 71, 72 are located respectively on each circular track having radial distance rt, r2 to the center of said disc 4.Each conductor71,72 occupied an appropriate angle 8 which is about 1200 in this embodiment and shall not exceed the angle of opening 11, so that when the disc rotates continuously, the transmitter 5 and the receiver 6 being conducted to act only when the spring contacts 46a, 47a of said terminals 46,47 getting in contact with said conductors 71,72 at their occupied angle; and cease to act as soon as the spring contacts 46a, 47a leave the conductors 71,72.
In other words, said transmitter 5 and receiver 6 act only within angle 8 and in an intermittent mood.
In addition to the conductors 71,72, the printed circuit plate 7 further contains upon the plate a circuit 51 for said transmitter 5 and a main oscillating and amplifying circuit 61 for said receiver 6 such as shown in Figs. 5 and 6, while the respective horns 52, 62 of the transmitter 5 and receiver 6 are disposed on said revolving disc 4 and connected via terminals 46, 47, spring contactors 46a, 47a, conductors 71,72 to said circuits 51, 61 to complete the supersonic wave transmitting and receiving circuits. The input side are connected in parallel with the ordinary backing signal circuit and the output side is connected in series with a sound/light alarm 8 having a buzzer 81 and an alarm signal lamp 82. The alarm 8 is disposed on the driver's panel such as shown as shown in Fig.
Referring once more to Fig. 3, a normal close micro-switch a is disposed on a supporting arm 15 projecting inward from the near center of the upper wall of section 1 b of the casing 1. The trigger 91 of said switch 9 is disposed upwardly right under the disc 4. The switch 9 as shown in Fig. 5, is connected in series between the power source B and the motor 2 while in the meantime in parallel with the reverse shift switch S of the car transmission. A projection 48 under the disc 4 serves to open the switch 9 when the disc 4 rotates to a position right on top of the switch 9.
Said device is mounted on the center of the rear bumper and operated as shown in Figs. 7 and 8 and is connected through lead wire I to the alarm 8 disposed on the driver's panel in the driver's cabin. Thecircuit shown in Fig. 5 having the notations to show:
B the original car battery, S1 the engine switch, F the fuse panel, S the reverse shift switch, L the backing signal lamp, 01 the system of the present invention.
Since all the notations have been detailed herein before, only schematic diagram is used to show their relationship in circuitry.
One of the preferred circuit of the transmitter 5 and receiver 6 is shown in Fig. 6, the oscillating circuit 51 and the amplifying circuit 61 are known to all and shall not be detailed further. Both circuits are disposed on the printed circuit plate 7 and only the sensing member or horn 52 and 62 are disposed on said revolving disc4. Such an arrangement together with the terminal 46,47 being able to revolve with the disc 4 and get in touch with the fixed conductors 71,72 to intermittently close and open the power source switch is the unique feature of the present invention.
Operation of the present invention is now detailed with Fig. 5. When the transmission gear is shifted to reverse position ready for the backing of the car, the reverse shift switch S is closed, then backing signal lamp L at the rear of the car is lighted and motor 2 of the present system 01 started, disc 4 with transmitter 5 and receiver 6 thereon rotates through reduction gear 3. When terminals 46,47 on disc 4 get in contact with conductors 71,72, transmitter 5 starts to transmit supersonic wave, and receiver 6 starts to work in the meantime and ready to receive the signal reflected from whatever obstacle behind.The action of transmitter/receiver is effective only within the angle 0 when the transmitter/receiver is in a position just within the opening 11 of the casing 1.The transmitted wave dispered rearward, scanning angle of which reaches almost as wide as 1800 as shown in
Figs. 7 and 8. When the wave gets in contact with any obstacle within the predetermined safety range, the wave would be reflected and received by the receiver 6 to actuate the circuit 61 to get the sound/light alarm 8 to perform the work and let the driver brake the backing car in time. As soon as the car finishes backing, the gear is shifted to "neutral" position, the switch S is opened, yet the disc 4 keeps to rotate until the projection 48 opens the switch 9 then the motor 2 stops. Since the projection 48 is disposed in opposite to the dust cover 42, therefore when the motor 2 stops, the dust cover is in position to cover right up the opening 11 and the transmitter 5 and receiver 6 are retained within the casing 1 to get protection from dust and weathering when the device is not in use, to avoid unnecessary damage.
The effective sensing distance can be predeter
mined at such as one meter both forthetransmitter and receiver under any scanning angle, such as shown in Fig. 9, the semi-circular range is known as safety range. In Fig. 10, at least one pair of variable
resistor 71 a, 71 b and 72a, 72b are used to substitute said conductors 71,72.A number ofseriesly connected resistors of various value can also be used as equivalent such as shown in Fig. 11,then a variable effective transmitting distance can be achieved depending upon the variation in the angle of scanning, transmitting distance being the longest at 0 then decreases with increasing of angle, till 90" the transmitting distance being the shortest, then again increases till the angle reaches 180 , at which the range becomes equal to that of 00. In such a way, even if the obstacle is at a deviated position behind the car, the effective range will be just the same as the obstacle is right facing the rear of the car. The backing operation will be much safer.
Furthermore, the transmitter 5 and receiver 6 are shown disposing at/down overstacking, evidently, the up/down positions are interchangeable and it is also practicable as to arrange transmitter/receiver left-right with each other. The circuitry of course can be varied to be different from that being shown in
Fig. 6. Further, disc 4 is designated to revolve 360" as in the embodiment, a rocking mechanism may also be added to couse the disc 4 rockering within the range of opening 11 thereby the scanning of the transmitting and receiving is effected within this range. All these modifications are within reach of those skilled of the art and shall no more be detailed here.
