Abstract
The invention provides an accelerator safety control device for preventing an accelerator pedal from being rapidly stepped when a driver steps on the accelerator pedal, which can effectively correct the error action of stepping the accelerator as a brake at a key moment of the driver, so that the accelerator pedal cannot be stepped to the bottom by one foot, and serious traffic accidents are avoided. The oil cylinder comprises at least one oil cylinder consisting of a piston rod, a piston and a cylinder body, wherein the piston rod connected with an accelerator pedal extends into the cylinder body to be connected with the piston, and the piston divides the space in the cylinder body into an oil return cavity at the upper part and an oil storage cavity at the bottom; an oil passage which is communicated with the oil return cavity and the oil storage cavity is formed in the piston, and at least one part of the oil passage is in a conical shape with a small upper part and a big lower part; the valve rod with the small upper part and the big lower part corresponding to the conical oil channel can be arranged in the conical oil channel in a vertically moving way.
Description
Technical field
The present invention relates to a kind of safety control device for automobile, relate in particular to a kind of throttle safety control.
Background technology
In daily traffic, as driver during with normal dynamics step on the accelerator, Das Gaspedal shrinks freely.We usually see the driver especially new hand run into emergency situation because nervous reaction do not come, mistake is stepped on throttle suddenly when brake, the speed that this moment, the driver trampled is often all violent especially, automobile can quicken rapidly, thereby causes the generation of accident.
If have a kind ofly when the violent accelerator pedal of driver, prevent that the tragedy that throttle safety control that Das Gaspedal is stepped on rapidly just can be avoided from having taken place.
Summary of the invention
The purpose of this invention is to provide a kind of when the violent accelerator pedal of driver, prevent the throttle safety control that Das Gaspedal is stepped on rapidly, it can effectively be corrected the misoperation that throttle is stepped on suddenly when brake at driver crucial moment, make Das Gaspedal to floor suddenly by a pin, to avoid serious traffic accident.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of throttle safety control, comprise the oil cylinder that at least one is made up of piston rod, piston, cylinder body, the piston rod that links to each other with Das Gaspedal stretches in the cylinder body and links to each other with piston, and piston becomes the oil back chamber on top and two spaces of shoe cream room of bottom to the separated by spaces in the cylinder body; Have the asphalt channel that is communicated with oil back chamber and shoe cream room on piston, at least a portion of asphalt channel becomes up-small and down-big taper; Can be arranged on up or down in the taper asphalt channel with the corresponding up-small and down-big valve rod of taper asphalt channel.
Beneficial effect of the present invention: during emergency brake, if step on the throttle pedal accidentally, Das Gaspedal presses piston rod and piston moves down, and shoe cream room is diminished, and the oil pressure of the hydraulic oil in the shoe cream room can raise immediately.But because up-small and down-big taper asphalt channel and corresponding valve rod, the oil pressure that the moment in the shoe cream room increases can make valve rod move from bottom to top, thereby makes valve rod contact with the taper asphalt channel and close the taper asphalt channel.Like this, piston rod just can not continue to move down again, and certainly, the Das Gaspedal that links to each other with piston rod also just can not be floored suddenly, and the speed of a motor vehicle can not raise rapidly, avoids or alleviated the harm of accident.Certainly, when normally trampling Das Gaspedal, valve rod can not closed the taper asphalt channel, and Das Gaspedal shrinks freely.
Technical scheme as a further improvement on the present invention makes piston rod be positioned at the retracing spring on cylinder body top when being provided with in normality between cylinder body and the piston rod.Retracing spring not only can increase the resistance when trampling Das Gaspedal, and when unclamping Das Gaspedal, retracing spring can also promote the piston rod return that moves up, make hydraulic oil from oil back chamber in asphalt channel flow back into shoe cream room.
As further improved technical scheme of the present invention, described oil cylinder is two, and the piston rod of two oil cylinders all is connected one and is used for the connecting panel that links to each other with Das Gaspedal.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
Referring to throttle safety control shown in Figure 1, comprise two oil cylinders 3, two guide rods 2, two retracing springs 1, connecting panel 4, two valve rods 5.Each oil cylinder includes piston rod 31, piston 32, cylinder body 33.The piston rod of two oil cylinders upper end all is connected and is used for the connecting panel 4 that links to each other with Das Gaspedal.Pass connecting panel 4 with piston rod 31 parallel guide rod 2, connecting panel 4 moved up and down the startup directional tagging.
Piston rod 31 lower ends are stretched in the cylinder body 33 and are linked to each other with piston 32, and piston becomes the oil back chamber 34 on top and 35 two spaces of shoe cream room of bottom to the separated by spaces in the cylinder body.Have the asphalt channel 36 that is communicated with oil back chamber and shoe cream room on piston, the bottom of asphalt channel is up-small and down-big taper asphalt channel part 361.Valve rod 5 moving up and down passes asphalt channel 36, and the bottom of valve rod 5 is and the corresponding up-small and down-big taper valve stem part 51 of taper asphalt channel part.When being provided with in normality between cylinder body 33 and the connecting panel 4, make piston rod be positioned at the retracing spring 1 on cylinder body top.
Working process of the present invention is: when needing emergency brake, if step on the throttle pedal accidentally, Das Gaspedal presses piston rod 31 and piston 32 moves down, shoe cream room 35 is diminished, oil pressure raises in the shoe cream room, make valve rod 5 move up, taper valve stem part 51 promptly can contact with the taper asphalt channel part 361 of asphalt channel 36 bottoms, thus closing oil path passage 36.Like this, piston rod 31 and connecting panel 4 just can not continue to move down again.Certainly, the Das Gaspedal that links to each other with connecting panel 4 also just can not be floored suddenly.This structure has guaranteed that Das Gaspedal can only slowly step on, and prevents that effectively Das Gaspedal from being stepped on suddenly, avoids the vehicle flat-out acceleration that causes therefrom.
Resistance when retracing spring 1 not only can increase accelerator pedal, when unclamping Das Gaspedal, retracing spring can also promote the returns that move up such as piston rod, connecting panel, makes hydraulic oil in asphalt channel 36 flow back into shoe cream room 35.
