Description
Technical field
The invention belongs to motor vehicle steering system part field, more particularly, relate to a kind of steering column of vehicle structure.
Background technology
On self-propelled vehicle, steering column of vehicle structure is the requisite parts of steering system.Steering gear structure is connected with bearing circle, but the rigid construction that the Steering gear structure of existing Steering gear structure is tubulose, when self-propelled vehicle bumps, can not there is crumple in the Steering gear structure of rigid construction, thereby can cause the collision of navigating mate and bearing circle and Steering gear structure, be easy to bring injury to navigating mate.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of simple in structure, can when bumping, guarantee Steering gear generation crumple, thereby guarantee the steering column of vehicle structure of navigating mate safety.
Solve above-described technical matters, the technical scheme that the present invention takes is:
The present invention is a kind of steering column of vehicle structure, described Steering gear structure comprises upper lever, lower pipe fitting, described upper lever one end is sleeved in lower pipe fitting, the upper lever other end is fixedly connected with bearing circle, the perforation that penetrates upper lever is set in upper lever, a plurality of stoppers are set in perforation, the both sides of perforation are respectively set with a card column, two card column bottoms are resisted against respectively on stopper, the end portion of two card columns is not set to protrude from the structure on upper lever surface, lower pipe fitting is hollow structure, lower pipe fitting inner wall arranges the hole clipping of two protrusions, when upper lever is sleeved in lower pipe fitting, the end portion of two card columns is not inlaid in a hole clipping.
Preferably, the upper inside wall of described perforation and inwall bottom arrange respectively two stoppers, when the suffered external force of upper lever surpasses setting value, the hole clipping of described lower pipe fitting and the card column of upper lever are set to the application of force to stopper and promote the structure that fracture occurs stopper.
Preferably, the termination portion of described card column is set to the spherical structure of protruding, and hole clipping is set to recessed spherical structure, when described upper lever is sleeved in lower pipe fitting, the end portion of each card column is not inlaid in a hole clipping, and termination portion and the hole clipping surface of described card column fit.
Preferably, between two stoppers in the upper inside wall of described perforation, be set to exist the structure in gap, between two stoppers on described inwall bottom, be set to exist the structure in gap.
Preferably, a stopper of the upper inside wall of described perforation respectively be positioned at its below inwall bottom on a stopper form one group of barrier assembly, in described perforation, comprise two groups of barrier assemblies, the bottom of two described card columns is resisted against respectively on two barrier assemblies.
Adopt technical scheme of the present invention, can obtain following beneficial effect:
Steering column of vehicle structure of the present invention, the upper lever that Steering gear is set to be set in together and lower pipe fitting, perforation is set in upper lever, many group block assemblies (every group of block assembly comprises stopper of upper inside wall and a stopper of inwall bottom) are set in perforation, in perforation, be set with again two card columns, card column is inlaid in the hole clipping on lower pipe fitting, such structure, when Steering gear is not subject to outside excessive power, the cooperation of card column and hole clipping, guaranteeing that upper lever and lower pipe fitting are fixing links together reliably, guarantee that navigating mate normally handles motor-driven vehicle going and turning to, when self-propelled vehicle bumps or when other surprisingly cause bearing circle to be subject to excessive external force, the power that bearing circle position is subject to is delivered to card column, and be delivered to hole clipping by card column, at this moment, excessive External Force Acting is in hole clipping and card column, card column is stressed shrinks in perforation, and act on stopper, because the intensity of stopper is when the design, set the setting value of a stressed rear generation fracture, therefore, when the external force from card column being subject to when stopper is greater than this setting value, stopper ruptures, card column is shunk in perforation, like this, between upper lever and lower pipe fitting, be connected disconnection, crumple in the downward pipe fitting of whole upper lever, played the stressed effect that cushions.Steering column of vehicle structure of the present invention, when self-propelled vehicle bumps, can guarantee Steering gear generation crumple, thereby avoids the Steering gear of rigid construction to damage because colliding navigating mate, thereby guarantees the safety of navigating mate.
