An air bag chamber is arranged at the center of the wheel seat; the wheel ring consists of two sections of wheel ring rods A connected with the supporting rod, at least two sections of wheel ring rods B and wheel coil rods C, wherein the number of the wheel ring rods C is greater than that of the wheel ring rods B by two sections; the wheel ring rods A are arranged on the wheel ring and are symmetrical about a straight line, wherein the straight line is arranged in the plane of the wheel coil and passes through the center of the wheel ring, and. The wheel ring rods A are respectively positioned between two sections of wheel ring rods C; and each section of wheel ring rods B is positioned between two sections of wheel ring rods C. After subjecting to the impact of greater external force, the steering wheel can be deformed to a great extent, thus effectively reducing the harm of the steering wheel on driver and also being convenient for the driver to save oneself or help others.

Description

Safe bearing circle is dismantled in deformable

Technical field

The present invention relates to automobile steering wheel.

Background technology

Automobile steering wheel is made up 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 through the dish seat, with the control vehicle travel direction.Existing steering wheel 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 " articulated safe bearing circle "; Comprise circular coil, sit crosslegged and be connected strut bar therebetween; Coil is that the coil bar C that coil bar A two-fold coil bar B and quantity equate with coil bar A forms by at least three sections with strut bar bonded assembly coil bar A, quantity; 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 through bulb is secondary, every section coil bar C is all wherein between two sections coil bar B.Though the bearing circle of this kind structure can produce distortion to a certain degree when receiving big external force collision, its deformation extent is very limited, can not reduce the injury that bearing circle causes chaufeur effectively.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 invention is to provide a kind of deformable and dismantle safe bearing circle, when it receives big external force collision, can produce distortion largely,, be convenient to simultaneously that navigating mate is saved oneself or he rescues to effectively reduce the injury that bearing circle causes chaufeur.

Safe bearing circle is dismantled in deformable according to the invention; Comprise circular coil, dish seat and be connected strut bar therebetween; Offer the air bag chamber on the dish seat; Coil manys two section coil bar C with strut bar bonded assembly coil bar A, at least two sections coil bar B and quantity than coil bar B by two sections to be formed, and coil bar A is on coil, to be positioned at coil plane, place and through the straight line symmetry 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 first bulb, and 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 the handle shape body that seat combines as a whole; Offer 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 vertically, handle shape body is provided with and bumps pearl, and an end of said strut bar is arranged in said 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 that bumps pearl is arranged in this position-limited trough, and the other end of strut bar is fixed with second bulb, and it is arranged in coil bar A and forms the bulb pair with coil bar A; Offer limited pit on second bulb, be provided with among the coil bar A and bump pearl, the pearl that bumps pearl is arranged in the limited pit on second bulb.

Coil bar A is made up of the base and cover plate; Cover plate is hinged with pedestal in the coil bar A outside, and coil bar A is provided with the cover plate latching device, 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, can cover plate be uncovered from pedestal, from coil bar A, take out with first bulb with said extension spring outer end.

The outer end of said extension spring is fixed through the rectangular cylinder and 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 through the straight line rotation at the first bulb center.

Said cover plate latching device is made up of with the locking plate that is installed on the coil bar A cover plate the button latch that is installed on the coil bar A pedestal.

When the coil bar A of this bearing circle partly receives big external force collision; Strut bar overcomes the spacing power of bumping pearl that is arranged on the handle shape body; Strut bar is slided and contraction in the dish seat in handle shape body; Simultaneously, in coil bar C, pulled out and produced bending, make bearing circle produce distortion largely with clashing into the adjacent extension spring of coil bar A.

When coil bar B, the coil bar C of this bearing circle partly receive big external force collision; Extension spring in the coil bar C that is clashed into is drawn out and produces bending; The coil bar B and the coil bar C that are clashed into are moved to bearing circle place under, thereby make bearing circle produce distortion largely.

After bump takes place; Bearing circle produces distortion but when will chaufeur propping up, chaufeur or other people can open the cover plate latching device, and cover plate is uncovered from pedestal; 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 deformable according to the invention is dismantled safe bearing circle and is received big external force collision; To produce above-mentioned distortion, with respect to the bearing circle of prior art, its amplitude of deformation is bigger; Buffering effect is better, thereby the injury that bearing circle causes chaufeur when reducing vehicle and having an accident can be arranged; And,, reliable guarantee is provided to the life security of chaufeur so chaufeur is saved oneself or he rescues because bearing circle can conveniently dismantle.And when abnormal driving state; Owing to bump pearl spacing to bulb; And with bulb bonded assembly rectangular cylinder be arranged in the effect of 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.
