Description
Technical field
The present invention relates to a kind of method of vehicle passive safety protection, particularly there is a kind of safety device that the modes such as deflection, compression buffering and buffering distortion are formed jointly.
Background technology
Along with the develop rapidly of society, automobile people life in day by day universal, the index of vehicle safety performance more and more receives publicity.When frontal crash of vehicles, no matter whether being equipped with air bag, all can there is direct or indirect making contact with bearing circle in human body.If bearing circle rigidity is very large, this will cause serious injury to human body.At present, although use comparatively ripe bearing circle protection mechanism can reach the object of compression energy-absorbing, there is no good buffer action; Bearing circle is to the injury of the human body splanchnocoel good solution of neither one all the time; Steering column can only axial stretching, cannot universally deflect, and increase more spaces can not to human body because of inertia anterior displacement; In existing steering hardware, during collision, bearing circle is not directly effectively solved this problem of injury of human body head and neck.
Summary of the invention
The present invention is directed to the problems referred to above design, provide that a kind of structure is simple, reliability is high, reusable device, to protect the life security of navigating mate under unsafe condition.
Technical scheme of the present invention is achieved in that
During automobile generation head-on crash, vehicle slows down due to primary collision, and human body is subject to comparatively Great inertia power effect and moves forward.First human chest can contact with bearing circle lower edge, and at this moment, bearing circle can, according to the position adjustment angle of human body thorax abdomen contact, progressively make bearing circle plane parallel with chaufeur chest, thus the area of contact of augment direction dish and chest, reduce to clash into pressure.The energy produced when bearing circle can adjust angle and absorbs on one side and human chest is clashed into, self-ly when stopping at the position parallel with chest locks.Meanwhile, the upper tubing string of steering column can have forward certain angular deflection, to increase the proal distance of human body, after upper tubing string contacts with the metallic support shell fragment of limiting device, at this apart from interior increase bearing circle and human contact's time.Under steering hardware drag effect, chest produces force of inertia and reduces gradually, and head part also can move forward with comparatively Great inertia power and contact with bearing circle upper limb.The cushion plate edge of bearing circle upper limb absorbs the Impact energy produced when contacting with head part, thus reduces bearing circle to the injury of human body head.Finally, the energy disperser in steering column starts to cushion vertically and progressively absorbs remaining energy.

Detailed description of the invention
With reference to accompanying drawing, the present invention is further described: as shown in Figure 1 and Figure 2, lower end, with the upper turning cylinder 4 of drum gear, is installed together with the tubing string 1 with female splines.Ball ring 11 and cylindrically coiled spring 12 are contained in tubing string 1 respectively, and lower turning cylinder 13 is arranged on tubing string 1 lower end, cylindrically coiled spring 12 pre-pressing and upwards compress upper turning cylinder 4 along axis by bowl-type ball ring 11; Spacing flange 2 and metallic support shell fragment 3 are equipped with in tubing string 1 upper end, and both are jointly to upper turning cylinder 4 limited location control action.Upper turning cylinder 4 is connected with frame of handwheel 6 by flange 5.In frame of handwheel 6 lower end, elastic metal sheet 10 is installed, eccentric self-locking device 9 is housed above elastic metal sheet 10.Frame of handwheel about 6 two spokes not only can play outside steering-effecting during normal driving, can also rotate certain angle around the axis of spoke, and this rotational action is through Quincunx elastic coupler and is delivered on band reel edge 8.As Figure 1-3, Quincunx elastic coupler is made up of the elastic caoutchouc 14 of pre-pressing, the rotating shaft of band reel edge 8 and the sleeve pipe of frame of handwheel 6 respectively.As shown in figure 3-2, there is bearing circle dish edge the spoke upper end of eccentric self-locking device 9, and bearing circle dish edge two ends are extruded with two keys, and are with reel edge 8 tail end to have keyway, so the key of eccentric self-locking device 9 inserts the keyway of band reel edge 8, realizes key and slides in keyway.Two band reel edge 8 are linked together by cushion plate edge 7, like this, by cushion plate edge 7, band reel edge 8, eccentric self-locking device 9, and the common card forming bearing circle.
The working process of whole device, as shown in Figure 4.When automobile generation head-on crash, vehicle slows down due to primary collision, and human body is subject to comparatively Great inertia power effect and moves forward.The working process of device is broadly divided into four-stage:
First stage, first human body thorax abdomen can contact with the straight flange bearing circle dish edge on the eccentric self-locking device 9 of bearing circle in device (this dish edge face area is larger).Then, eccentric self-locking device 9 eccentric wheel starts to rotate.Because eccentric radius constantly increases, therefore spoke rotation can cause key to slide outside keyway, and eccentric self-locking device 9 can, with the spoke rotation of sleeve of movable band axis dish edge 8 around frame of handwheel 6, make the card of whole bearing circle rotate around spoke axle when rotating.Meanwhile, because band reel edge 8 is around the spoke rotation of sleeve of frame of handwheel 6, the key protruded in the pipe spreader of frame of handwheel 6 compresses with the arc-shaped slot on band reel edge 8 S. A. the elastic caoutchouc 14 be placed in groove jointly, therefore elastic caoutchouc 14 produces antagonistic force, plays the effect of first-level buffer.Bearing circle card adjusts angle gradually because of the press-in of thorax abdomen, to increase larger area of contact, thus reduces chest pressure.When eccentric self-locking device 9 eccentric rotary, because the eccentric radius of eccentric self-locking device 9 constantly increases, eccentric self-locking device 9 rotates pressure and wedging elastic metal sheet 10, elastic metal sheet 10 is deformed and apparatus with shock absorbing.Under elastic caoutchouc 14 and the common opposition of eccentric self-locking device 9, bearing circle card stops operating gradually, and eccentric self-locking device 9 stops operating and self-locking, and remaining impact energy is passed into next stage buffer gear.
Subordinate phase, the impact forces compress cylindrically coiled spring 12 of upper turning cylinder 4, produces bounce and kicking motion.Upper turning cylinder 4 departs from after spacing flange 2 vertically just can free deflection, due to impact direction forward, upper turning cylinder 4 can deflect forward with larger speed, go up turning cylinder 4 when deflecting into certain angle and touch the metallic support shell fragment 3 be arranged on spacing flange 2, metallic support shell fragment 3 is out of shape gradually and cushions the deflection energy from upper turning cylinder 4, reaches level 2 buffering.
Phase III, the chest of people produces force of inertia and reduces gradually, but head also can move forward with comparatively Great inertia power.Human body head, when contacting with cushion plate edge 7, can absorb the impact energy of generation when head part contacts due to cushion plate edge 7 and deform, the head of human body therefore can be protected to greatest extent not to be subject to grievous injury.
Fourth stage, at spacing flange 2 with under the dual restriction of upper turning cylinder 4 drum gear profile of tooth, the upper turning cylinder 4 of constantly deflection, in the process of compression downwards, stops deflection and is just returning gradually.Meanwhile, ball ring 11 is by remaining greater impact energy transferring to cylindrically coiled spring 12, and gradually reduced by the cylindrically coiled spring 12 that lower turning cylinder 13 is fixed in tubing string 1 and cushion and absorb energy, final third stage buffer gear absorbs last impact energy.
