Abstract
The utility model relates to an automatic backing alarm for motor vehicles, which can remind the driver of stopping backing via acoustic and optical show when the backing edge of the motor vehicle is near people or obstacles. The utility model mainly comprises an optical frequency transmitter, an optical frequency receiver, a speaker arranged in the driver's cab and an indicating lamp, etc; the optical frequency transmitter can be reformed from the rear lights of the existing motor vehicles; the optical frequency receiver mainly comprises a photosensitive tube, a frequency amplifier, a rectifier, a relay, etc.
Description
The utility model relates to and a kind ofly can show by sound, light during near people or obstacle when the backing automobile back, reminds the device of driver's stop reversing.
Now backing automobile has later been watched from a height or a distance clear by the driver, and wants the limit bevelling to look back at, operating difficulties not only, and because the vehicle body that has is excessive, and the car dead aft has people or thing driver cannot see, consequently cause the accident.
The purpose of this utility model is that design is a kind of when the backing automobile back can be sent sound during near people or obstacle automatically, light shows, the device of reminding driver's stop to move backward.
The utility model mainly by optical frequency projector, optical frequency receptor and be contained in the operator's compartment loudspeaker and (or) indicator lamp etc. partly forms.The optical frequency projector is connected successively by oscillating circuit 4, potential device 2, power amplifier 3 and taillight and forms, taillight can utilize the existing taillight of self-propelled vehicle to transform, change the emission angle of light, make the irradiating width of light and body width suitable, in case irradiation side object produces flase alarm.
The optical frequency receptor is provided with photosensitive tube 6, and the optical frequency that photosensitive tube receives enters rectifier 9 rectifications by signal conditioner 5, frequency amplifier 8, arrives relay 10 again, makes the actuating of relay.The contact heel of relay is connected on the loudspeaker and indicator lamp of operator's compartment, also can receive simultaneously on the loudspeaker that are contained in the car back.
The utility model has the advantages that: when the backing automobile back can be sent sound during near people or obstacle automatically, light shows, remind the reversing of driver's stop, guarantee reversing safety.
Accompanying drawing 1 is an optical frequency Transmitter side block diagram, wherein: 1, projector binding post; 2, potential device; 3, power amplifier; 4, oscillating circuit.
Accompanying drawing 2 is block schemes of optical frequency receptor, wherein: 5, signal conditioner; 6, photosensitive tube; 7, direct current amplifier; 8, frequency amplifier; 9, rectifier; 10, relay; 11, receive a crime report to apply to install and put; 12,13, connect brake equipment.
Accompanying drawing 3 is optical frequency acceptor circuit figure.
The optical frequency projector of my trial-production is by changing taillight reflected light angle the taillight on both sides not to be shone to the outside, both sides, but to dead aft and irradiation to the inside.The optical frequency receptor also receives only the reflected light in car dead aft and the cooresponding scope of width over sides of car body, here optical frequency amplifier adopted is integrated circuit 2002, relay is 12 volts; Oscillating circuit in the optical frequency projector adopts TA7331P autoexcitation.
Claims (1)
1, a kind ofly can show by sound, light during near people or obstacle when the backing automobile back, remind the backing automobile autoalarm of driver's stop reversing, it is characterized in that forming by optical frequency projector, optical frequency receptor and the loudspeaker and the indicator lamp that are installed in the operator's compartment; The optical frequency receptor is provided with photosensitive tube (6), and photosensitive tube links with signal conditioner (5), frequency amplifier (8), rectifier (9), relay (10) successively by lead, and the contact heel of relay is connected on the loudspeaker and indicator lamp of operator's compartment; The optical frequency projector is connected successively by oscillating circuit (4), potential device (2), power amplifier (3) and taillight and forms.
