Description
Technical field
The utility model is a kind of bearing circle servo-unit, specifically is a kind of telescopic bearing circle servo-unit.
Background technology
When driving a car, the especially quick intersection both hands steering wheel rotation that chaufeur must not stop when reversing is put in storage or carried out the turning of wide-angle, very inconvenience.For addressing the above problem, usually on bearing circle, install servo-unit additional, as Chinese utility model patent 98238561.7,98203057.6,99246592.3,00239466.9,01217469.6,01246513.5, all be to adopt to utilize lever principle, at the bearing circle edge one rotating handle is set, is hold by one hand handle and does circular motion that bearing circle is rotated is arbitrarily angled.The bearing circle servo-unit of Cai Yonging all is fixed in the prior art, only consider the action need when reversing is put in storage or carried out the turning of wide-angle, bring inconvenience and potential safety hazard at normal driving-activity in meeting and ignored the bearing circle servo-unit that has more.During such as normal driving, the bearing circle servo-unit of projection can stop that the hand of chaufeur grips bearing circle, at the bearing circle servo-unit of situation lower process such as sudden stop even can damage chaufeur.
Summary of the invention
The utility model improves the existing steering wheel servo-unit for remedying the deficiencies in the prior art, has proposed a kind of flexible and convenient to use, safe and reliable telescopic bearing circle servo-unit.
For achieving the above object, the utility model adopts following technical scheme.
Telescopic bearing circle servo-unit comprises:
Anchor fitting comprises base and fastener, and fastener is located at base one side;
Rocking bar comprises handle and connecting rod, and handle is located at the connecting rod top, and the bottom of connecting rod is located on the base;
Described handle lower hollow, in be provided with axle sleeve, axle sleeve and connecting rod are connected; Described connecting rod comprises at least two mutually nested and can stretch slip joints, is provided with spring in the connecting rod, and an end of spring is connected on the base, and the other end of spring is connected in the axle sleeve.
During use, base is fixed on the bearing circle, launches, make handle exceed bearing circle so that use at the slip joint of the tension force effect lower link of spring by fastener; If the health of chaufeur under the situation of emergency brake is because inertia leans forward when compressing handle, spring is subjected to the external force pressure contraction that slip joint is regained, and this moment, handle was confined under the plane of bearing circle, avoids projection injury chaufeur.
As improvement of the technical scheme, the bottom sides of described handle is along being provided with stopper, and stopper is the convex edge that is arranged on handle bottom sides edge, then is provided with the holding part of coupling stopper on the described base, and the holding part is an elasticity overhead kick.During normal driving, for guaranteeing not service orientation dish servo-unit of safety, this moment handle is pressed down the slip joint of regaining connecting rod, convex edge in the stopper slips over the elasticity overhead kick of holding part, and under the tension force effect of spring, form and hold, under the surface that is confined to bearing circle that handle is firm, neither can hinder normal driving at this moment, avoid again chaufeur being damaged at the bearing circle servo-unit of situation lower process such as sudden stop.
As improvement of the technical scheme, described stopper is discontinuous multistage, and the interval between each section be able to hold the holding part and pass through.When needing service orientation dish servo-unit, slightly turning handle makes the interval breach on the stopper align with the elasticity overhead kick, be pushed out at the tension force effect lower handle of spring, and the slip joint of expansion connecting rod.
As improvement of the technical scheme, described axle sleeve is socketed on the slip joint of connecting rod outermost, and the axis place of axle sleeve also is provided with the axle center, and axes sleeve is connected in the interior slip joint of connecting rod; The outer, bottom in axle center is provided with hook, and an interior slip joint inwall of connecting rod then is provided with the step that cooperates hook.By cooperating of axle center and connecting rod slip joint, increased the stressed limit of handle greatly, service orientation dish servo-unit is more safe and reliable.
In the technique scheme, along being provided with the circle that stops that anti-skidding takes off, the top of a slip joint of described connecting rod outermost then is provided with and cooperates the stop part that stops circle in the bottom of described axle sleeve.
In the technique scheme, described fastener is a snap ring, and snap ring is provided with opening, the two ends bolt together of opening.
In the technique scheme, described snap ring inside face has a plurality of anti-skidding projections.
In the technique scheme, be provided with liner in the described snap ring, the shape of liner and snap ring coupling, the inside face of liner also has a plurality of anti-skidding projections.
Compared with prior art, positive role of the present utility model is:
Solid and reliable, easy to operate, only need stir just steering wheel rotation fast and effectively of handle gently; And have stretching structure, and can hide the bearing circle servo-unit during normal driving, the bearing circle servo-unit more can automatic drawing back under unforeseen circumstancess such as emergency brake, avoids injuring chaufeur.
