Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with detailed description of the invention, this utility model is expanded on further.
Refer to Fig. 1 to Fig. 4, this utility model provides a kind of technical scheme: brake device for car during a kind of mis-accelerator pressing, including mis-accelerator pressing judgment means and execution device, described mis-accelerator pressing judgment means includes stay cord 21, stay cord coiler 22 and linear displacement transducer 23, described stay cord 21 one end is connected with gas pedal 1, the other end is connected with described stay cord coiler 22, described stay cord coiler 22 is arranged on vehicle body, for rolling lax stay cord 21, described linear displacement transducer 23 is arranged on the stay cord 21 between gas pedal 1 and stay cord coiler 22, and electrically connect with the electronic control unit 3 of automobile, described execution device includes the driving mechanism that the piston rod of the auxiliary oil cylinder 51 and described auxiliary oil cylinder 51 of driving connected with automobile brake system oil inlet pipe 4 moves, and described driving mechanism electrically connects with described electronic control unit 3. described stay cord 21 is rigidity stay cord, such as steel wire rope, and is arranged on the top of gas pedal 1.The two ends of linear displacement transducer 23 are connected to described stay cord 21. Automobile brake system is brake fluid system, and human pilot promotes master cylinder to be entered in oil inlet pipe 4 by hydraulic oil by the pedal that touches on the brake, so that disk brake work, and then wheel is braked.
Operation principle of the present utility model: stay cord 21 is arranged on the top of gas pedal 1, keeps tensioning state by stay cord coiler 22. Under normal circumstances, human pilot is slowly to step on gas pedal 1, and stay cord 21 is followed gas pedal 1 and moved down, and the linear displacement transducer 23 being arranged on stay cord 21 is also followed stay cord 21 and moved, and it can record a less displacement. Needing braking when human pilot runs into emergency, but during mis-accelerator pressing, it steps on the speed of gas pedal quickly, and now, linear displacement transducer 23 can record a bigger displacement, and will record signal and reach electronic control unit 3 and process. Setting for judging displacement value during mis-accelerator pressing on electronic control unit 3, after exceeding this displacement, electronic control unit 3 controls the work of described driving mechanism, makes the outside oil extraction of auxiliary oil cylinder 51, and then makes liquid braking device to wheel braking.
Therefore, when brake device for car during a kind of mis-accelerator pressing of the present utility model can solve to need brake hard under emergency case, the problem making life, property loss because of mis-accelerator pressing so that the safety coefficient of automobile improves.
Further improvement as such scheme, described stay cord coiler 22 includes reel 221, rotating shaft 222 and plane scroll spring 223, described reel 221 is two that are oppositely arranged on vehicle body, the two ends of described rotating shaft 222 are respectively installed with a reel 221, the interlude of rotating shaft 222 is cased with described stay cord 21, the outer end of described plane scroll spring 223 is connected with reel 221, and the inner is connected with rotating shaft 222. The two-end part of rotating shaft 222 is in the opposite exterior lateral sides of two reels 221, and it can rotate around reel 221. Described plane scroll spring 223 is arranged on the opposite exterior lateral sides of two reels 221. The effect of stay cord coiler 22 only need to roll lax stay cord 21, therefore above-mentioned arranges simple in construction.
Further improvement as such scheme, described mis-accelerator pressing judgment means also includes the chute 24 and the pulley 25 that are horizontally installed on vehicle body, described linear displacement transducer 23 is slidably matched with described chute 24, stay cord 21 ran between linear displacement transducer 23 and gas pedal 1, around being located on described pulley 25, is provided with the baffle plate 251 preventing stay cord 21 from departing from from pulley 25 on pulley 25.
