Background technology

The bearing circle of automobile is comprised of coil, dish seat and the strut bar of circle, and strut bar combines as a whole it between coil and dish seat, and bearing circle is connected with the axis of orientation of vehicle by the dish seat, with the control vehicle heading.Existing bearing circle generally is rigid construction, and when vehicle had an accident, because this rigidity bearing circle can not produce geometry deformation, thereby it often caused fatal harm to chaufeur.

The patent No. is that the utility model patent of ZL200620111129.0 discloses a kind of " active-nodal safety steering wheel ", comprise circular coil, sit crosslegged and be connected to strut bar therebetween, coil is comprised of the coil bar C that at least three sections coil bar A, quantity that are connected with strut bar coil bar B that is coil bar A twice and quantity equate with coil bar A, coil bar A is evenly distributed on the coil, lay respectively at wherein between two sections coil bar B, and be connected with coil bar B by bulb is secondary, every section coil bar C is all wherein between two sections coil bar B.Although the bearing circle of this kind structure can produce distortion to a certain degree when being subject to larger external force collision, its deformation extent is very limited, can not effectively reduce the injury that bearing circle causes chaufeur.And after the bearing circle distortion, because the rebound action of spring, bearing circle still props up chaufeur, and makes chaufeur owing to the reason of bearing circle can not be left operator's compartment.

Summary of the invention

The purpose of this utility model provides a kind of Flexible Safety bearing circle, when it is subject to larger external force collision, can produce largely distortion, and the injury that chaufeur is caused to effectively reduce bearing circle is convenient to simultaneously that navigating mate is saved oneself or he rescues.

Flexible Safety bearing circle described in the utility model, comprise circular coil, dish seat and be connected to therebetween strut bar, offer the air bag chamber on the dish seat, coil manys two sections coil bar C by two sections coil bar A that are connected with strut bar, at least two sections coil bar B and quantity than coil bar B and forms, coil bar A is on coil, with be positioned at coil planar and symmetrical through the straight line at coil center, and lay respectively at wherein between two sections coil bar C, every section coil bar B is all wherein between two sections coil bar C.

Coil bar C has the centre hole that cross-sectional plane is square, be provided with two extension springs in the centre hole of every section coil bar C, the inner of extension spring is fixed with the square piston with the centre hole bearing fit, the outer end of extension spring is fixed with the first bulb, the first bulb lays respectively among coil bar A and the coil bar B, forms the bulb pair with coil bar A and coil bar B.

The both sides of dish seat are provided with and coil a handle shape body that combines as a whole, offer vertically the through hole that is square with the cross-sectional plane that is communicated with of air bag chamber that coils seat on the handle shape body, be provided with collision bead on the handle shape body, one end of described strut bar is arranged in described through hole and cooperates with handle shape body space, the both sides of this end of strut bar offer the curved position-limited trough in bottom surface, the pearl of collision bead is arranged in this position-limited trough, and the other end of strut bar is fixed with the second bulb, and it is arranged in coil bar A and forms the bulb pair with coil bar A; Offer limited pit on the second bulb, be provided with collision bead among the coil bar A, the pearl of collision bead is arranged in the limited pit on the second bulb.

Coil bar A is comprised of the base and cover plate, cover plate is hinged with pedestal in the coil bar A outside, be provided with the cover plate latching device on the coil bar A, during cover plate latching device locking, cover plate is fastened on the pedestal to be connected as a single entity with pedestal, when the cover plate latching device is opened, cover plate can be uncovered from pedestal, be taken out from coil bar A with the first bulb with described extension spring outer end.

The outer end of described extension spring is fixed by rectangular cylinder and the first bulb, rectangular cylinder is limited between the pedestal and cover plate of coil bar A, and the port of coil bar B, make the rectangular cylinder can only be around vertical with plane, bearing circle place and rotate through the straight line at the first bulb center.

Described cover plate latching device is comprised of the locking plate that is installed in the button latch on the coil bar A pedestal and be installed on the coil bar A cover plate.

When the coil bar A of this bearing circle partly is subject to larger external force collision, strut bar overcomes the spacing power that is arranged on the collision bead on the handle shape body, strut bar is slided and contraction in the dish seat in handle shape body, simultaneously, bending is pulled out and produced to the extension spring adjacent with being knocked coil bar A in coil bar C, make bearing circle produce largely distortion.

As the coil bar B of this bearing circle, when coil bar C partly is subject to larger external force collision, extension spring in the coil bar C that is knocked is drawn out and produces bending, the coil bar B and the coil bar C that are knocked are moved to below, plane, bearing circle place, thereby make bearing circle produce largely distortion.

After bump occurs, bearing circle produces distortion but when will chaufeur propping up, chaufeur or other people can open the cover plate latching device, cover plate is uncovered from pedestal, the first bulb of extension spring outer end is taken out from coil bar A, coil bar A is separated with coil bar C, thereby with bearing circle dismounting, to realize saving oneself or he rescues.

When Flexible Safety bearing circle described in the utility model is subject to larger external force collision, to produce above-mentioned distortion, with respect to the bearing circle of prior art, its amplitude of deformation is larger, buffering effect is better, thereby the injury that bearing circle causes chaufeur when reducing vehicle and having an accident can be arranged; And because bearing circle can conveniently dismantle, therefore chaufeur is saved oneself or he rescues, provide reliable guarantee to the life security of chaufeur.And when abnormal driving state, because collision bead is spacing to bulb, and the rectangular cylinder that is connected with bulb and the effect that is arranged in the square piston of coil bar C, effectively prevented coil bar A, coil bar B and the coil bar C rotation when normal the use, guaranteed that bearing circle can not produce distortion when normal operating condition.
