Specific embodiment
It is one embodiment of hand brake system of the present invention and its actuation means also referring to Fig. 2, Fig. 3 and Fig. 4.
The present embodiment hand brake system includes brake apparatus 50 and actuation means.Brake apparatus 50 includes ratchet 51 and tooth plate
52。
Actuation means include the handle 10 for being designed to " 7 " type, bindiny mechanism 20 and a switching mechanism.Bindiny mechanism 20 can
To use the snakelike arm of parking brake.
Handle 10 is provided with manual brake button 11 and actuator bracket 12, and the manual brake button 11 is located at the end of the handle 10.
The one end of bindiny mechanism 20 is connected with handle 10, and the other end is connected with brake apparatus 50, the bindiny mechanism 20 and handle
10 constitute " Z " type structure.
Switching mechanism includes selector bar 30, drag-line and fixed mechanism 40.Selector bar 30 is installed on actuator bracket 12, when pressing
During lower manual brake button 11, selector bar 30 is promoted by manual brake button 11, is slided backward on actuator bracket 12.Drag-line is provided with steel wire rope
31 and protective sleeve of pulling cable 32.The front end 311 of steel wire rope 31 is fixed in the steel wire rope fixed column 121 on actuator bracket 12, and end is worn
It is fixed on the ratchet 51 of hand brake system after crossing fixed mechanism 40.The shape of protective sleeve of pulling cable 32 is according to handle 10 and bindiny mechanism
20 structure design, protective sleeve of pulling cable is shaped as " Z " type in the present embodiment, is set on steel wire rope 31, its front end 321 and conversion
Bar 30 is connected, and end is fixed on fixed mechanism 40.Fixed mechanism 40 is fixed in bindiny mechanism 20, which is provided with a regulation
Knob 41, adjusting knob 41 can adjust the position of the end of protective sleeve of pulling cable 32 so as to adjust the initial position of the end of steel wire rope 31.This
In embodiment, adjusting knob 41 uses thread fiting mode, can also be using modes such as spring or anchor points in practical application
Realize the regulation to the terminal position of protective sleeve of pulling cable 32；Used between manual brake button 11 and selector bar 30 in the present embodiment and be fixedly connected
Fit system, various fit systems can also be used in practical application：Such as by manual brake button 11 and the one of selector bar 30
Shaping, or that the manual brake button 11 and the selector bar 30 are individually installed in into handle is first-class.
Refer to Fig. 5 and Fig. 6.When manual brake button 11 is pressed, manual brake button 11 promotes conversion to the left in the presence of power F
Bar 30 slides L length on actuator bracket 12.Selector bar 30 connects protective sleeve of pulling cable 32, therefore protective sleeve of pulling cable 32 is pushed away by selector bar 30
Move and slide L length to the left.And the end of protective sleeve of pulling cable 32 is fixed on fixed mechanism 40, therefore protective sleeve of pulling cable 32 is by selector bar
30 and the crimp of fixed mechanism 40 to middle bulging, the L length transitions that its front end is postponed are the bulging arc of protective sleeve of pulling cable 32
Length.Steel wire rope 31 in protective sleeve of pulling cable 32 is wrapped up by protective sleeve of pulling cable 32 also and then there is identical bulging to centre, but,
Cannot be moved because the front end 311 of steel wire rope is fixed in steel wire rope fixed column 121, the bulging arc length incrementss in the middle of it can only
Supplemented by end so that end moves right, and thereby produces a pulling force T to the right, so that band pawl 51 is moved, make spine
Pawl 51 departs from tooth plate 52.Ratchet 51 is provided with return spring 53 in the present embodiment（Refer to Fig. 4）, when relieving manual brake button 11
When, ratchet 51 is combined in the presence of return spring 53 with tooth plate 52, and to pulling steel wire rope 31, and then drive manual brake button 11
Return, this process departs from the process of tooth plate 52 conversely, repeating no more with above-mentioned with pawl 51.
Embodiment of the present invention actuation means replace metal pushrod using drag-line, using switching mechanism, before protective sleeve of pulling cable
End is connected with selector bar, and end is fixed on fixed mechanism, and the front end of steel wire rope is fixed on handle, end and ratchet phase
Even；When manual brake button is pressed, selector bar promotes protective sleeve of pulling cable, and protective sleeve of pulling cable and steel wire are made using the crimp of protective sleeve of pulling cable
Relative motion is produced between rope, the protective sleeve of pulling cable motion of handle end is converted into the motion of the steel wire rope at ratchet end, realize opponent
Brakes is controlled.Meanwhile, the shape of drag-line is easily changed, and can be applied to various special shaped handles.
Above by reference to the preferred embodiments of the present invention have been illustrated, those skilled in the art do not depart from the scope of the present invention
And essence, there can be various flexible programs to realize the present invention.For example, as the shown partially of one embodiment or description
Feature can be used to another embodiment obtain another embodiment.Preferably feasible embodiment of the invention is these are only, not
Therefore interest field of the invention is limited to, the equivalence changes that all utilization description of the invention and accompanying drawing content are made are both contained in
Within interest field of the invention.
