Abstract
The present invention relates to an energy-absorbing type steering tube column, and is characterized by that said tube column has a hollow body, in the hollow cavity the hydraulic power cylinder, hydraulic valve and cylinder are set successively from top end downward; the steering column piston positioned in the hydraulic power cylinder is fixedly connected with steering column bottom end which can be axially slided, and the steering column top end can be fixedly connected with steering wheel, and the described hydraulic valve can be used for transferring pressure from hydraulic power cylinder into cylinder piston by means of oil circuit. Said invention utilizes the pressure produced by steering wheel to human body to control hydraulic valve.
Description
Technical field:
The present invention relates to be applied in the safety guard on the vehicle.More specifically say so when collision happens, chaufeur is implemented the device of safety guard-safeguard.
Background technology:
Because the residing ad-hoc location of chaufeur, when collision happens or other accident, bearing circle is to one of key factor of the safety formation prestige association of chaufeur.
At present, having used the safety method on luxury car is the equipment safety air bag.Safety air bag adopts electric control mechanism, provides control signal by acceleration pick-up.What safety air bag was implemented is initiatively protection, as long as the relevant acceleration information of vehicle reaches setting value, no matter in fact whether chaufeur is subjected to compressing of bearing circle, safety air bag all will be opened.In addition, expensive safety air bag is disposable device, is difficult to extensively implement on common vehicle.
Summary of the invention:
Technical matters to be solved by this invention is to avoid above-mentioned weak point of the prior art, provides a kind of cost performance higherly, difficult enough extensively to be useful on the various vehicles, can be effectively the pressure from bearing circle to be carried out energy-absorbing, chaufeur implemented the energy-absorption type column of training gear of safety guard-safeguard.
The technical scheme that technical solution problem of the present invention is adopted is:
Constructional feature of the present invention is that described tubing string has hollow cavity, in the Kong cavity, sets gradually fluid power cylinder, hydraulic valve and cylinder from the top therein; But the direction column piston that is arranged in fluid power cylinder connects firmly the direction post bottom at axial slip, and direction capital end connects firmly bearing circle; Described hydraulic valve by to the perforation of oil circuit in the future the transmission of pressure of self-hydraulic power cylinder to cylinder piston.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention comes the modulated pressure valve with bearing circle to the pressure that the human impact produces, and the oil pressure that is produced is carried out energy absorbing at the gas dome of cylinder.Thereby slow down impulsive force, avoid or alleviate personal injury.Its protection action accurately and reliably.
2, the present invention is simple in structure, easy to implement, can be widely used in various vehicles, and repeated usage.
The drawing explanation:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
Referring to accompanying drawing, the tubing string 14 in the present embodiment has hollow cavity, in the Kong cavity, sets gradually fluid power cylinder 5, hydraulic valve 9 and cylinder 11 from the top therein.But the direction column piston 2 that is arranged in fluid power cylinder 5 connects firmly in the bottom of the direction post 4 of axial slip, and the top of direction post 4 connects firmly bearing circle 1.Described hydraulic valve 9 by to the perforation of oil circuit in the future the pressure of self-hydraulic power cylinder 5 be passed to cylinder piston 13 rapidly.
Shown in the figure, in concrete the enforcement, hydraulic valve 9 adopts the pilot-operated type structure, is made of priority valve 10 and main valve 8, and its guide's valve pocket is communicated with fluid power cylinder 5 by damping hole 7, and the main valve oil circuit is arranged in the sidewall of tubing string 14.
In order to guarantee that in the exoergic process of cylinder 11, bearing circle 1 slowly resets, in the present embodiment, between fluid power cylinder 5 and hydraulic valve 9, be provided with residual valve 6, residual valve 6 is under pressure at bearing circle 1, unidirectional unlatching when direction column piston 2 promotes to exert pressure forward.
In order to guarantee good seal, be provided with check valve sheet 3 and bowl ring in the end of direction column piston 2, and on cylinder piston 13, be provided with y-shaped ring 12.
After automobile bumps, the bearing circle 1 at chaufeur human impact top, direction column piston 2 is pushed ahead, residual valve 6 is opened, be positioned at behind the damping hole 7 priority valve 10 because of pressure greater than the response pressure of setting, priority valve 10 is at first opened.Immediately, because big pressure differential forms, main valve 8 is unlocked, and pressure oil enters the end of cylinder piston 13 by the main valve oil circuit that is arranged in the tubing string sidewall, and promotes cylinder piston 13, make it produce pressure to the gas in the air chamber 15, and pressure gas absorbs energy.At this moment, bearing circle 1 is as being arranged on the elastic body, and impulsive force is slowed down, avoided human body is damaged.Along with the disappearance of extraneous pressure, air chamber 15 begins to release energy, and by oil return line direction column piston 2 is slowly pushed back original control position, and mode of operation is recovered.Under the nominal situation, hydraulic valve 9 cuts out, and the main valve oil circuit is cut off, and bearing circle 1 remains under the normal and stable operation state.
