Description
Technical field
The utility model belongs to field of automobile, is related to the parking brake structure on a kind of automobile, particularly a kind of vapour
Parking brake unlocking structure on car.
Background technology
Parking brake is an important component on automobile, it can auxiliary braking, so as to keep the steady of storing cycle to lean on, with
Pin touch on the brake brake principle it is different, parking brake is connected on rear brake-shoe using steel wire pull line and wheel is braked.
In order to ensure the use reliability of parking brake, parking brake is provided with locking device, parking brake need to press when unlocking unblock on parking brake by
Button.As the improvement of people's living standards, to the aesthetic of parking brake on automobile also more and more higher, the structure of parking brake is also by original
Single straight handle type develops into more aesthetically pleasing " 7 " font, the change of parking brake pattern it is unlocked associated mechanisms there has also been it is new
Change.At present in Automobile Design, parking brake unblock button is fixed together with connecting rod, is connected by Coupling Shaft with ratchet,
In unblock operating process, press after unblock button, connecting rod drives pawl rotation by Coupling Shaft, so as to complete unblock.But
It is that in this structure, the size that connecting rod can not have larger radian and ratchet to be commonly designed is larger, in " 7 " font parking brake
Because of the limitation of arrangement space in structure, this structure can not be applicable.
Chinese patent (notification number：CN203592976U, publication date：2014-05-14) disclose a kind of Z-shaped parking brake solution
Latch mechanism, including push-button socket and control arm, the parking brake unlocking mechanism are additionally provided with steel wire rope assembly, ratchet, tooth plate, and ratchet is fixed
In control arm, steel wire rope assembly includes chuck, steel wire rope, upper interstage sleeve, protecting pipe, lower interstage sleeve and dop, the two ends point of steel wire rope
Be not fixedly installed chuck and dop, steel wire rope one end by chuck and push-button socket clamping, the steel wire rope other end by dop with
Ratchet one end clamping, steel wire rope is fixed on control arm by upper interstage sleeve and lower interstage sleeve, and steel wire rope is moved in protecting pipe, push-button socket
Elastic component is provided between upper interstage sleeve.
Parking brake unlocking mechanism in above-mentioned patent document overcomes the elastic force of spring using button press, so as to drive steel wire rope
Ratchet is promoted, realizes that the unlocking manner in unblock, the structure is not laborsaving enough.
The content of the invention
The utility model is directed to the above mentioned problem of existing technology presence there is provided the parking brake unlocking structure on a kind of automobile,
Technical problem to be solved in the utility model is：It is how more laborsaving when using the unblock of parking brake unlocking structure.
The purpose of this utility model can be realized by following technical proposal：
A kind of parking brake unlocking structure on automobile, parking brake includes claw plate, can matched with the ratchet on the claw plate

It is more laborsaving during lock.
Button in the technical program can use China Patent No. for the mounting structure in CN201420389302.8, from
And the pressing and reset of button can be realized.The end of button can also be hinged with unlocking the end of cam, in unblock cam
With on the inwall of handle cavity between reduction torsion spring is installed.
In parking brake unlocking structure on above-mentioned automobile, forced contact point of the button on the unblock cam is
The tie point of A points, the unblock drawstring and the unblock cam is B points, and the pin joint of the unblock cam is C points, A points and C
The distance between point is a, and the distance between B points and C points are b and a ＞ b.It is convex that button promotes the arm of force of unblock cam to be more than unblock
Wheel pulls the arm of force of unblock drawstring, more laborsaving using lever principle.
In parking brake unlocking structure on above-mentioned automobile, jointed shaft is connected with the inwall of the handle cavity, it is described
It is connected in the middle part of unblock cam on the jointed shaft, the side of the unblock cam has what is be connected with the unblock drawstring
Pulling arm, one end of the unblock cam has the promotion arm being connected with the button.So it is easy to unlock the installation of cam
And connection, it can also facilitate button to promote the setting of the arm of force of unblock cam and the arm of force of unblock cam pulling unblock drawstring.
In parking brake unlocking structure on above-mentioned automobile, rope sling is additionally provided with the handle, the rope sling is located at described
Unlock between cam and the ratchet, the unblock drawstring, which is slided, to be plugged in the rope sling.Rope sling is in hollow structure, and unblock is drawn
Rope slip is plugged in rope sling, and rope sling is fixed, and rope sling plays guide effect, it is ensured that stabilization during unblock drawstring movement can
By property, and ensure the accuracy in direction, reduce friction and resistance, further the external force needed for reduction unblock.
In parking brake unlocking structure on above-mentioned automobile, the handle includes holding section and bending segment, the holding section
Formed with bending segment on angle, the holding section and be coated with sheath.It is so both attractive in appearance, frictional force is increased again, it is convenient to grip.
In parking brake unlocking structure on above-mentioned automobile, the inner of the button is plugged in the holding section, outer end
The end face of the holding section is stretched out, the inner promotion arm end by push rod and the unblock cam of the button leans.
So facilitate operating with for button, promote the promotion arm for unlocking cam during button press by push rod, it is put around pin joint
It is dynamic, positioned at unblock cam opposite side pulling arm just can synchronous hunting, drive unblock drawstring to be unlocked.
In parking brake unlocking structure on above-mentioned automobile, the unblock cam is located in the holding section, described to grip
One end that section installs the button is front end, and the other end is rear end, and the pulling arm of the unblock cam is towards the rear end of holding section
Setting is tilted upward, the promotion arm of the unblock cam is set diagonally downward towards the front end of holding section.Radial direction in handle is empty
Between it is limited, said structure be easy to unlock cam installation connection, while also allowing for the accurate transmission of external force.
Compared with prior art, by setting unblock cam in the utility model, the form of unblock drawstring will be pushed directly on
Be converted to the form for pulling unblock drawstring so that the stress of unblock drawstring is more concentrated, moment preferably can be drawn along unblock
Bending or fold will not occur in the handle in the axis transmission of rope, unblock drawstring, so that resistance when reducing drawstring movement, solution
It is more laborsaving during lock.
