Abstract

The invention discloses a crashworthy bumper apparatus, which is related to a car bumper and the traveling safety. The invention resolves the problems that the existing cars can not provide the warning and prevention of potential rear-end collision accidents in advance, and once the collision happens, the car body cannot bear great impact force to cause severe damage to the car and endanger the life safety of passengers and drivers. The car bumper (2) (the front and rear of a bodywork) is provided with ultrasonic (or infrared ray, and wireless speed measurement radar), a speed measuring emission apparatus (6) and a speed measuring receiving apparatus (7), a rubber strip(1) is arranged in front of the bumper(2), and a spring(3) is arranged behind the bumper(2), the apparatuses (1), (2) and (3) are connected with a special enhanced car frame (5) to form a whole by bolts.

Description

Anti-collision bumpers device

Technical field:

The present invention is relevant with the bumper and the traffic safety of automobile.

Background technology:

Present existing vehicle is not equipped with the warning device that tests the speed automatically, to the timely prediction and alarm of contingent collision, when the driver finds to want to avoid to handle will be by collision the time also late.The front is not equiped with rubber strip on the bumper, and the back is not equiped with spring assembly on the bumper, is " confronting the tough with toughnees " fully during collision, vehicle frame is also Unreinforced special, " knocking into the back " collision accident consequence taking place generally all compare seriously, may cause car body badly damaged, casualties.

Summary of the invention:

The purpose of this invention is to provide a kind of simple in structure, with low cost, durable in use, security performance is good, " knock into the back " generation of collision accident that can warning and prevention, two can make car bear big impact, very safe and practical bumper system.

This device has exploitation and is worth greatly, highly versatile, the characteristics that any style vehicle all is suitable for.

The present invention is achieved in that

Anti-collision bumpers device be present vehicle obtained increased newly on the basis of using bumper below four bigger device parts:

1, as among Fig. 61 be shown in the transmitter that tests the speed that ultrasound wave (or infrared ray, radio velocity radar) speed measuring device is equipped with in (or car body front and back proper site) above bumper design, the position is shown among Fig. 66, and ultrasound wave (or infrared ray, the radio velocity radar) receiver that tests the speed is housed, the position is shown among Fig. 67.

2, as among Fig. 3, Fig. 41 be shown in bumper thick stick frame front rubber strips (blocks) be installed.

3, as among Fig. 3, Fig. 43 be shown in bumper thick stick frame back many buffer springs be installed.

4, shown among Fig. 3, Fig. 44, be connected with vehicle frame shown among Fig. 3, Fig. 42 again and be combined as an integral body with screw.

5, special as shown in Figure 5 reinforced vehicle frame.

More than 1,2,3,4 devices be installed in the front and back of car, effect has:

1, because of design the ultrasound wave velometer is housed, car can be monitored the front and back spaces of vehicles in motion automatically, and sends the sound and light alarm signal according to the distance of spaces of vehicles to the driver; Spacing is near more, and the sound and light alarm signal is rapid more, and with the current danger that exists of prompting driver, at this moment the driver can take urgent counter-measure, can prevent and avoid the generation of " knocking into the back " collision accident as possible.

2, there is rubber strip the front of anti-impact bumper thick stick frame because of design and installation, there is spring assembly the back, rubber strip, spring have absorption, cushion, reduce the effect of impact, make vehicle when the collision accident " is knocked into the back " in the middle generation of running at high speed, reduce impact, to reduce to the damage of vehicle and driver and crew's extent of injury.

3, special reinforced vehicle frame is rigidity, the intensity in order to strengthen main body of vehicle frame, to improve the ability to bear of vehicle body to big impact, " knock into the back " in the middle generation of running at high speed to reduce vehicle, car is use up at utmost to escort to take advantage of personnel's life security by badly damaged degree when bumping against.

Being used in combination of above-mentioned three kinds of devices can greatly strengthen the security of existing vehicle ', significantly reduces or reduce that vehicle " knocks into the back " in the middle generation of running at high speed, car is jeopardized the problem of personnel's life security by badly damaged when bumping against.

Ultrasound wave velometer principle:

Moving object detector ultrasonic transmit circuit principle as shown in Figure 1.Moving object detector ultrasonic signal received signal treatment circuit principle as shown in Figure 2.

The moving object detector designs and produces according to hyperacoustic Doppler effect.It is made up of ultrasonic transmitter and ultrasonic signal receiving processor circuit two parts.At ordinary times, ultrasonic transmitter sends the constant amplitude ultrasonic signal of fixed-frequency, when running into stationary object, what receiver received is the constant amplitude reflected signal identical with transmission frequency, after processing and amplifying, output be the control signal of a null value, circuit state remains unchanged.Transmit when running into moving object, because Doppler effect, the reflected signal that receiver is received is the mixed signal of transmission frequency and deviation frequency.This mixed signal is by exporting a control signal after the processing of amplifier, and available this signal is made indicator signal or is used for controlling the action of executive circuit, to realize the purpose of control automatically.

Shown in Figure 1 is the ultrasonic transmit circuit schematic diagram, the multivibrator that it is made up of the NE555 circuit of IC1 and be made up of jointly the CD4069 of inverter ic 2.Oscillating impulse by the output of NE555 circuit, its forward by the amplification and shaping circuit that compose in parallel by F2, F3 after, add to the utmost point of a ultrasonic emitting T40-16, its negative sense adds to amplification and the shaping circuit that is composed in parallel by F4, F5 by F1 after oppositely, add to another utmost point of ultrasonic launching head then, drive the ultrasonic emitting head from both direction, launching effect is increased greatly.

Fig. 2 receives and signal processing circuit for ultrasound wave.Ultrasound wave receives the ultrasonic signal that a R40-16 is used for receiving ultrasonic emitting signal and object reflection, if when in effective detecting area, not having mobile object, transmit and reflected signal that ultrasound wave reception head is received all are the 40KHZ ultrasonic signals that amplitude equates, uPC4570 integrated circuit the two poles of the earth voltage amplification through IC1A, IC1B, behind the amplitude detection of D1 and D2, at this moment output signal is zero.

If moving object occurred in detecting area, then ultrasound wave receives the signal that head receives, and transmitting of existing constant amplitude has the frequency and the continuous reflected signal that changes of amplitude that reflect by moving object again.This mixed signal is amplified through uPC4570 the two poles of the earth voltage signal amplifier of IC1A, IC1B, Beat Signal of output behind the amplitude detection of D1, D2.If the pulse signal by IC1B output is the pulse signal that a frequency and amplitude constantly change, then can be in the adjusting of the detecting circuit signal of C4 output by R12 by the electric current exported after D1, the D2 detection, be coupled to IC2A, IC2B by C7, R6 and carry out signal and amplify.By IC2B output pulse signal through having amplified, carry out impedance conversion through emitter-follower Q1 after, be coupled to D3, D4 by C9 and carry out voltage multiplying rectifier, pulse voltage is transformed to DC voltage.IC3A forms voltage follower, is used for impedance conversion.IC3B and R16, R14 form voltage comparator, regulate reference voltage with R14.By 2 pin of the voltage of the IC3B output NE555 by being capacitively coupled to IC4, signal makes LED flash luminous, loudspeaker sounding alarm by the 3 pin output of NE555 after the NE555 processing and amplifying.
