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, the center of dish seat offers the air bag chamber, coil is comprised of three sections coil bar A, coil bar B that are connected with strut bar and coil bar C, wherein two sections coil bar A are on coil, with be positioned at coil planar and symmetrical through the straight line at coil center, another section coil bar A is positioned in the middle of described two sections coil bar A on coil; All have at least one section coil bar B and quantity to Duo one section coil bar C than coil bar B between per two sections coil bar A, coil bar A and coil bar B are all 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 groove that is communicated with the air bag chamber that coils seat on the handle shape body, be provided with the 3rd bulb with the handle bar in the groove, it is secondary that the 3rd bulb and handle shape body form bulb, described groove slits the upper surface of handle shape body logical, described handle bar outer end protrudes from handle shape body end face and towards coil bar A, the handle bar can only be rotated around its axis, and rotate to coil top around the 3rd bulb, handle bar and the 3rd bulb axially offer through hole along the handle bar; Be provided with handle lever lock locking apparatus at handle shape end of body, it stops the handle bar to rotate to the coil top around the 3rd bulb; The outer end of described 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, offers spacing pit on the second bulb, is provided with collision bead among the coil bar A, and the pearl of collision bead is arranged in the spacing pit on the second bulb; The inner of described strut bar is arranged in the through hole and handle bar and the 3rd bulb free-running fit of handle bar and the 3rd bulb, and its both sides offer the curved position-limited trough in bottom surface, are provided with collision bead on the handle bar, and the pearl of collision bead is arranged in this position-limited trough; Dish seat bottom axially offers the slot to make way that is communicated with described groove near handle shape body place along strut bar.
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.
Described handle lever lock locking apparatus is the button latch, and it is installed in the both sides of handle shape end of body.
When the coil bar A of this bearing circle partly is subject to larger external force collision, strut bar overcomes the spacing power of the collision bead on the handle bar that is arranged on the 3rd bulb, strut bar is slided and contraction in the dish seat in the 3rd bulb and handle bar, 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 handle lever lock locking apparatus on the handle shape body, to remove handle lever lock locking apparatus to the locking of strut bar, then upwards lift coil bar A, coil bar A and strut bar will rotate to bearing circle top around the 3rd bulb, thus make the inconsistent part of bearing circle and chaufeur produce the bending that makes progress and realize chaufeur save oneself or he rescues.In addition, can also cover plate be uncovered from pedestal by the cover plate latching device is opened, 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 the mode of bearing circle dismounting is realized 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 upwards bend and conveniently dismantle, so 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.
