The specific embodiment
As shown in Figure 1, mainly comprise having according to the mis-accelerator pressing emergency braking mechanism of present embodiment and refuel the Das Gaspedal 1, brake pedal 2, engine igniting coil 3, control Das Gaspedal 1 of stroke and flame-out braking distance and be converted into the switching mechanism of flame-out braking distance, when Das Gaspedal 1 is in flame-out braking distance, be connected the link gear of Das Gaspedal 1 and described brake pedal 2 from refueling stroke.
Refueling stroke and flame-out braking distance accounts for 3/5ths and 2/5ths of Das Gaspedal 1 stroke respectively, and when refueling stroke, automobile can fully be raised speed when refueling the terminal point of stroke, and automobile reaches maximum speed.When flame-out braking distance, trample Das Gaspedal 1, engine off then, the speed of a motor vehicle reduces rapidly.
Switching mechanism is to realize that Das Gaspedal 1 is assigned the key mechanism of oiling stroke and flame-out braking distance simultaneously.Switching mechanism mainly comprises acceleration cable 40, engine off normally closed switch 42 and open circuit spring 43.One end of acceleration cable 40 links to each other with the damper of carburettor 7, the aperture of control damper, and when Das Gaspedal 1 was in the terminal point of oiling stroke, the aperture of damper reached maximum position; Engine off normally closed switch 42 is serially connected on the primary circuit of engine igniting coil, during automobile normal running, engine off normally closed switch 42 is in closure state, the disconnection of engine off normally closed switch 42 realizes by open circuit spring 43, open circuit spring 43 is arranged in the middle of the engine off normally closed switch 42, and when open circuit spring 43 was elongated, the one end contacted engine off normally closed switch 42, make it to disconnect, this moment, driving engine will stop working.Because open circuit spring 43 is serially connected on the acceleration cable 40, when the terminal point of Das Gaspedal 1 to its oiling stroke, it is maximum that the aperture of the damper of carburettor 7 reaches, at this moment, and when trampling Das Gaspedal 1, the right-hand member of acceleration cable 40 is subjected to right-hand pulling force, because its left end and damper are fixed together and can not be moved, this moment, pulling force passed to the open circuit spring 43 that is serially connected on the acceleration cable 40, and open circuit spring 43 will be stretched, realize engine off, reach the braking purpose.
Though this example is passed through the distribution to the stroke of Das Gaspedal 1, made but to trample when being not easy to occur wanting to refuel in the driving process and excessively caused the situation of braking, still can not avoid the bad steerman of some driving habit simply step on the accelerator and cause the brake, therefore, be provided with the alarm set of when refueling the terminal point of stroke, reminding chaufeur in Das Gaspedal 1.Alarm set is to realize its prompting function in the following way:
Alarm set is included in the buzzer phone of the sound that can give the alarm when circuit is connected and is serially connected in often opening on the pull up circuit of buzzer phone reminds switch 10, often open the two poles of the earth one termination power+12V that reminds switch 10, the positive tip node of another termination buzzer phone, when Das Gaspedal 1 is positioned at the terminal point of its oiling stroke, often open and remind switch 10 closures, the buzzer phone sound that will give the alarm reminds chaufeur to reach the oiling terminal point.
Reach best braking effect, it still is not enough only depending on engine off to reach braking, and link gear then is the key mechanism that realizes drag.As Fig. 2, shown in Figure 3, link gear comprises the L shaped interlock armshaft of captiveing joint with the other end same axis of universal driving shaft 50 in a universal driving shaft 50 that an end and brake pedal 2 are fixedly connected and an end 51, be used to install the interlock axle bed 52 of L shaped interlock armshaft 51, the other end of L shaped interlock armshaft 51 is positioned at the front lower place of Das Gaspedal 1, and on this end, be provided with by plain bearing 53, direction with running car is the place ahead, when Das Gaspedal 1 is in the oiling stroke, L shaped interlock armshaft 51 is separated with Das Gaspedal 1, when Das Gaspedal 1 is in flame-out braking distance, Das Gaspedal 1 is pressed in the plain bearing 53 that is positioned at Das Gaspedal 1 front lower place of L shaped interlock armshaft 51, after Das Gaspedal 1 enters flame-out braking distance, continue to trample Das Gaspedal 1, then brake pedal 2 can be driven by link gear and depress, and causes drag.
As shown in Figure 4, mis-accelerator pressing emergency braking mechanism according to present embodiment is described consistent substantially with embodiment 1, different is that in this example, Das Gaspedal 1 has the extension 13 of stretching out cabin dividing plate 6, one end of acceleration cable 4 directly links to each other with the extension 13 of Das Gaspedal 1, when trampling Das Gaspedal 1, Das Gaspedal is rotated relative to cabin dividing plate 6, and pulling acceleration cable 4 moves right, so, the aperture of control damper.
Comprehensive the foregoing description, according to mis-accelerator pressing emergency braking mechanism of the present utility model when the cruising, trampling Das Gaspedal raises speed to car, before entering flame-out braking distance, the speed of a motor vehicle can reach the requirement of travelling fully, therefore, generally be can not occur excessively trampling and make driving engine flame-out situation occur to take place.Just in case, how involuntarily stepped on, remind chaufeur then have alarm set, guarantee that cruising is unaffected.And when emergency occurring under panic-stricken situation, chaufeur Das Gaspedal when brake pedal is stepped on, can step on sufficient Das Gaspedal, this moment, Das Gaspedal entered flame-out braking distance, car will be under the effect of the double brake power of flame-out braking and drag, slow down rapidly, and then stop the generation that finally avoids traffic accident.
