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 by the dish seat, with the control vehicle heading.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 made up 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.Though the bearing circle of this kind structure can produce distortion to a certain degree when being subjected to 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 is subjected to big external force collision, can produce distortion largely, to effectively reduce the injury that bearing circle causes chaufeur, be convenient to simultaneously that navigating mate is saved oneself or he rescues.

Safe bearing circle is dismantled in deformable of the present invention, comprise circular coil, dish seat and be connected 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, to be positioned at the straight line symmetry at plane, coil place and process 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, fixedly there is the square piston with the centre hole bearing fit the inner of extension spring, fixedly there is first bulb outer end of extension spring, 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, 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 that bumps pearl is arranged in this position-limited trough, and the other end of strut bar fixedly has 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, 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, cover plate can be uncovered from pedestal, be taken out from coil bar A with first bulb with described extension spring outer end.

The outer end of described extension spring is fixed by 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 rotate through the straight line at the first bulb center.

Described cover plate latching device is made up 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 subjected to 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, 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 distortion largely.

When coil bar B, the coil bar C of this bearing circle partly are subjected to big 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 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, 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 of the present invention is dismantled safe bearing circle and is subjected to 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 because bearing circle can conveniently dismantle, so chaufeur is saved oneself or he rescues, provide reliable guarantee to the life security of chaufeur.And when abnormal driving state, owing to bump pearl 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.
