Specific embodiment
The utility model provides the pivot pin being applied on automobile tail-hood telescopic rod.Below in conjunction with attached drawing to the utility model
Technical solution is described in detail, so that it is more readily understood and grasps.
Applied to the pivot pin on automobile tail-hood telescopic rod, as shown in Fig. 2, being used for and the ball-and-socket on automobile tail-hood telescopic rod
1 is matched, realizes that the pivotable movement of automobile tail-hood opens or closes.
As depicted in figs. 1 and 2, pivot pin includes fixing for the tack ball end 2 matched with ball-and-socket 1, for pivot pin
Fixing end 3 and the connecting column 4 between tack ball end 2 and fixing end 3.
The both ends of automobile tail-hood telescopic rod all have ball-and-socket 1, and a pivot pin, one of pivot is coupled in each ball-and-socket 1
The fixing end 3 of pivot pin is fixed on the connector of automobile tail-hood, and the fixing end 3 of another pivot pin is fixed in automobile trunk
Connector on, by the flexible of automobile tail-hood telescopic rod, Relative angular displacement is realized at ball-and-socket 1 and tack ball end 2.
Wherein, avoiding space 5 is equipped between tack ball end 2 and ball-and-socket 1, which prevents ball-and-socket 1 and tack ball end
There are interference between 2, it is ensured that tack ball end 2 is smooth with the relative motion of ball-and-socket 1, and there is no obstruction senses, it is ensured that automobile tail-hood
Activity it is smooth, be in addition also less prone to generate relative motion abrasion.
It should be noted that connecting column 5 is tapered, and connecting column 5 by tack ball end 2 to 3 orient diameter of fixing end gradually
Greatly.Such structure ensured the fixing intensity of pivot pin, tack ball end 2 and ball-and-socket 1 there are certain displacement stroke, therefore tack
Being restricted between ball end 2 and connecting column 5 with junction only allows certain diameter, and uses the connection of traditional cylindrical type
5 intensity of column is lower, can not adapt to the use demand of high frequency time, and the structural strength of pivot pin can be improved by the design of taper, increases
Its service life is added.
In another embodiment of this case, as shown in figure 3, being equipped with escape groove in ball-and-socket 1, tack ball end 2 is in pivotable movement
When, which can be reduced the contact at tack ball end 2 with 1 inner wall of ball-and-socket, improve the flexibility of revolution at tack ball end 2, simultaneously
Also the abrasion that can lower tack ball end 2, prolongs the service life.
In addition, pivot pin be by cylinder profile carry out turning it is molding, the connecting column 5 of taper can also reduce material loss,
And reduce the abrasion of turning mechanism.
And the taper α of connecting column 4 should not be too large, the scope of application is 10 °≤α≤20 °.The excessive then connecting column 4 of taper
Axial dimension is restricted, the too small effect for not having structural strengthening of taper.
α=14 ° described in the specific embodiment of this case, this design is relatively reasonable, meets actual demand, certainly can be with
Select taper α=15 °, taper α=13 °.It is larger to intensity effect less than 13 °.
Refinement description is carried out to this case, fixing end 3 includes fixed plunger 31 and stationary gland portion 32.
It specifically describes, the fixing seat for fixed pivot pin is cylindrical body, inside offers to wear for fixed plunger 31 and connects
Matching hole, and stationary gland portion 32 i.e. abutted against for the top end face with the fixing seat, it is ensured that the stability of pivot pin.
In addition, it is straight that the diameter in stationary gland portion 32 is at least fixed plunger 31 in order to increase the mating stability of pivot pin
2 times of diameter.It is so docked between fixing seat more reliable.
Arc-shaped transition 6 is equipped between connecting column 4 and stationary gland portion 32.6 one side of arc-shaped transition reduces turning hardly possible
On the other hand degree also plays contribution to its structural strength.
The end of fixed plunger 31 is equipped with chamfering 7.The chamfering 7 can play the role of mating guiding.
Finally, the outer surface of pivot pin is equipped with scuff-resistant coating.
Specifically, scuff-resistant coating is three rank coloured silk zinc layers, on the one hand makes the outer surface of pivot pin more attractive, on the other hand logical
The reflective abrasion condition that can obtain pivot pin for crossing outer surface, is easy to identification when maintenance.
In preferred embodiment, scuff-resistant coating with a thickness of 5 μm ~ 8 μm.This thickness coating is able to satisfy the application environment of pivot pin
The wear resistance of demand, it is ensured that the service life of pivot pin.
By above description it can be found that the utility model is matched using tack ball end and ball-and-socket, the two relative displacement
It is more smooth, and reduce wear intensity between the two.The connection post design of taper can increase the structural strength of pivot pin, increase
Its service life.The particular design of fixing end increases the mating stability of pivot pin.On the one hand three rank coloured silk zinc layers increase pivot
The wear-resisting property of pivot pin, on the other hand its degree of wear is visually screened.
The technical solution of the utility model is fully described above, it should be noted that the tool of the utility model
Body embodiment is simultaneously not limited by the description set out above, and those skilled in the art exist according to the Spirit Essence of the utility model
All technical solutions that structure, method or function etc. are formed using equivalents or equivalent transformation, all fall within this reality
Within novel protection scope.
