Description

Preventing motor-vehicle is pressed the protective device of thrusting into

Belong to the fender guard that prevents power actuated vehicle harm pedestrian life security.

Existing power actuated vehicle is when fast running, because unexpected situation suddenly takes place, utilize the existing brake of self-propelled vehicle can not prevent that the accident of pressing the people to thrust into from taking place by actv., thereby ten million people has been lost protect expensive life, also have some vehicles to cause car collision or the like in order to hide the pedestrian, this has all caused great loss to the country and people.

Purpose of the present invention is exactly to design a kind of device that can prevent that power actuated vehicle from pressing the people or thrusting into and disable, and simple in structure, easy to install.

The object of the present invention is achieved like this; Power actuated vehicle position (being former bumper/spoiler position substantially) foremost, the former bumper/spoiler of car is unloaded down, press preventing motor-vehicle the device main body partial fixing of thrusting on the car beam with screw or other method.Control part is installed in the operator's compartment.

The block body of base portion forms part and all is recovered at ordinary times by back plate (Fig. 1-1), and with vehicle body hitch (Fig. 2-24), la m (Fig. 1-2) is in the body shell frame that header board (Fig. 2-4) and side plate (Fig. 1-3) rivet welding are formed.The upper and lower part gear mesh body forms part, and both are arranged above and below, whole before face shell (Fig. 2-23) close on the body shell frame by the front button, all in addition parts all detain the pass within it, constitute aesthetic in appearance.

Base portion by the body shell frame, whole before face shell (Fig. 2-23), little cylinder (Fig. 2-32), stingy cylinder high-pressure air source body (Fig. 2-37), and block body forms part; Bottom master's supporter (Fig. 1-5), master cylinder (Fig. 1-10), top master's supporter (Fig. 1-9), ground connection supporter (Fig. 1-7), main piston (Fig. 1-11), main piston rod (Fig. 1-12), pull bar (Fig. 1-13), master cylinder high-pressure air source body (Fig. 1-17), bottom dictyosome master restrict (Fig. 1-19), bottom dictyosome (Fig. 1-2 0), top dictyosome master restricts (Fig. 1-2 1), and dictyosome parts such as (Fig. 1-2 2) in top is formed; Reticulate body also can be with amounting to withdrawal, and the gummed cloth of fan shape replaces.Also available other class block body.

Control part is by the infrared receiving element of human body (Fig. 2,3-28), speed of a motor vehicle switching electrical signals device (Fig. 3-44), amplifier (Fig. 3-43), switching device (Fig. 3-45), composition such as security personnel's push button (Fig. 3-46) part of etc.ing.

When unexpected dangerous situation took place, within the infrared receiving element of human body institute energy received signal distance, amplifier will amplify this signal pedestrian in danger so, but enlargement ratio is subjected to speed of a motor vehicle control.This is because speed of a motor vehicle switching electrical signals device is mounted in the microgenerator (the rapid pulse table with the transformation of the way is replaced former rapid pulse table) in the special rapid pulse table of changing a social system.It can be exported and the moment voltage that is directly proportional of the speed of a motor vehicle, removes the control amplifier enlargement ratio with this voltage, so just reaches the automatically controlled purpose.If if distance and two kinds of mixing conditions of car speed this moment of pedestrian in danger as mentioned above and car can make the prior regulation of amplifier output can make the electric signal of switching device conducting, switching device is with conducting so.(this device infrared exoelectron control part branch judges that automatically various speed of a motor vehicle people are apart from the car function how far this device should be opened automatically in other words).The power supply that leads to the detonation body that can ignite (Fig. 3-38) in the stingy cylinder high-pressure air source body (Fig. 3-37) is so just connected, and the power supply that leads to the detonation body that can ignite (Fig. 3-51) in additional brake gear (Fig. 3-50) the brake high-pressure air source body (Fig. 3-58) is simultaneously also connected.Volatile like this high pressure gas will promote small cylinder piston (Fig. 2-33) drive small cylinder piston bar (Fig. 2-34) and whole preceding face shell (Fig. 2-23) leaves the body shell frame.Because travelling forward of face shell makes firing circuit cut-off switch (Fig. 2,3-29) outage before whole, makes the blow out of an engine.Alarm sound contactor (Fig. 2,3-30) is connected simultaneously, and the sound gives the alarm to make alarm song circuit (Fig. 3-52).When the face shell moves to and leaves the body shell frame before whole, master cylinder firing switch (Fig. 2,3-31) is connected, make the power connection of the detonation body (Fig. 1,3-18) that can ignite in the master cylinder high-pressure air source body, make the high pressure gas of detonation press to main piston, make it to promote that main piston drives piston rod, pull bar makes upper and lower part master's supporter drive upper and lower part dictyosome master rope and dictyosome is opened, form block body in the car front, with this block body pedestrian in danger is pushed to the place ahead or both sides, reach the purpose that prevents collision of motor-driven vehicle.Be installed near the former brake drum with screw or other method simultaneously and the additional brake gear (Fig. 3-50) of the brake that can link under the effect of the high pressure gas of detonation, make vehicle self-actuating brake at once.Reach the purpose of interlocking brake.Because the effect of stingy cylinder automatic pressure reducing valve (Fig. 2-36) makes the air pressure in the little cylinder that acts on whole preceding face shell reduce to the pressure of predesignating, make whole preceding face shell that the function of slowing down bump be arranged in addition.

If the driver presses security personnel's push buttons (Fig. 3-46) and can play and the above same function.

If consider it is ice and snow road, preventing that car from taking the least important seat at a square table can be in advance turn-off the BK Brake Switch (Fig. 3-48) of whether interlocking, and has not braked with regard to not interlocking like this, is according to circumstances braked by the driver.

If vehicle is under steam because a variety of causes causes brake failure, the driver can press unintended emergency BK Brake Switch (Fig. 3-49) and make it to force brake so, if circuit is in the interlocking braking state, but electricity in the effect of unilateral conduction body (Fig. 3-47) with regard to problem such as can not cause that protective device is opened.

If dangerous situation disposes, at first open the master cylinder venting behind the power cutoff main supply switch (Fig. 3-59) and chew (Fig. 1-15), open master cylinder and block (Fig. 1-16) automatically, take out the master cylinder high-pressure air source body of detonation.Little cylinder is because the effect of automatic pressure reducing valve, just can open little cylinder with hand and block the stingy cylinder high-pressure air source body that (Fig. 2-39) takes out detonation automatically, moving top master's supporter after this makes pull bar push away a main piston rod and a main piston, drive bottom master's supporter, ground connection supporter and bottom dictyosome master rope, the bottom dictyosome, parts such as top dictyosome master rope and top dictyosome are all regained in the body shell frame.Then change master cylinder high-pressure air source body new, shut master cylinder and after the card face shell before whole is made it to detain the pass on the body shell frame to pusher automatically, this moment is because the effect of permanent magnet (Fig. 2-27) makes whole preceding face shell can not leave the body shell frame voluntarily because of vehicle operating.Afterwards stingy cylinder high-pressure air source body is changed newly, shut little cylinder again and block automatically.Because whole preceding face shell button closes motion the alarm sound contactor is disconnected simultaneously, the ignition circuit cut-off switch is connected, make master cylinder firing switch (Fig. 2-31) disconnection.Then opening brake venting and chewing (Fig. 3-55), opening brake automatically card (Fig. 3-57) the brake high-pressure air source body (Fig. 3-58) that takes out detonation change and shut brake card automatically after new.But more than work all finish after opening power main supply switch (Fig. 3-59) just.This has just finished whole operations, makes it to restore, and this moment, vehicle can normally move, if there is dangerous situation just to get final product from finishing the above operation again.
