Description
Technical field
The present invention relates to a kind of transmission mechanism of hatch door outdoor handle, it is applied to realize hatch door outdoor handle by interior on civil aircraft hatch door
The mechanism being turned out.
Background technique
Currently, for civil aircraft hatch door, outdoor handle, which mostly uses, to be rotated upwardly and downwardly or the form of left-right rotation.For turning up and down
Dynamic scheme, because outdoor handle configuration influences, it is often necessary to the beam structure of hatch door is interrupted or weakens, and beam structure is hatch door
Main load-carrying construction, performance have great influence to hatch door entirety load ability.For being located at the cargo door etc. of afterbody
Form hatch door, handle position are higher with respect to enabling personnel, and opening handle process is unfavorable for enabling personnel force, and maneuverability is bad.
For the outdoor handle scheme of left-right rotation, because its rotation direction and cabin door structure are interfered, so its movement needs more additions one
Outdoor handle is bounced or is overturn outward by step, away from cabin door structure, is rotated further by driving hatch door later and is opened, such handle
Opening process is relative complex, and maneuverability is poor, and mechanism form is also relative complex.
The right-hand side handle mechanism opened from inside to outside, the arrangement of outdoor handle can be to avoid interrupting beam structure.When enabling, the right-hand side
Handle directs out rotation, and mechanism is easy to operate, and operator can choose hand or hands and be pulled outwardly outdoor handle, force direction symbol
Close ergonomics.
Its Handle axis of the outdoor handle opened from inside to outside is vertical with hatch door mechanism driving axis.Currently, between vertical axis
Transmission, what civil aircraft hatch door generallyd use is spatial four-bar mechanism, but spatial four-bar mechanism is for the biography of two transmission shafts
Dynamic angle has certain limitations, and requires to maintain a certain distance between two transmission shafts, cannot achieve in conplane
Transmission between two vertical axises, this significantly limits the layout and design of hatch door mechanism.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of transmission mechanism of hatch door outdoor handle, which is not only grasped
Vertical property is good, and does not influence cabin door structure layout, while ensure that handle opening process is simply unrestricted.
In order to solve the above problem, the specific technical solution of the present invention is as follows: a kind of transmission mechanism of hatch door outdoor handle, including
Lock shaft, hatch door beam structure and outdoor handle, it is characterised in that: right-hand side arbor, the axis and lock of right-hand side arbor are connected on outdoor handle
The axis of axis is arranged vertically；Right-hand side arbor upper end connects lower crank, and one end of lower crank is using Handle axis as shaft, lower crank
Other end connection linkage linkage, linkage linkage pass through on hatch door beam structure after the strip grooves that are arranged be arranged on lock shaft
Upper crank connection.
The linkage linkage specific structure are as follows: be sequentially connected lower crank idler wheel, upper limit from the bottom to top on connecting rod
Idler wheel and upper crank idler wheel, wherein lower crank idler wheel is located in the roller groove being arranged on lower crank；Upper limit idler wheel is located at hatch door
In the strip grooves of beam structure；Upper crank idler wheel is located in the roller groove of upper crank setting.
It the axis coaxle of the upper limit idler wheel and lower crank idler wheel and is vertically arranged.
It is equipped with lower limit idler wheel between the upper limit idler wheel and lower crank idler wheel, is set below hatch door beam structure
There is limit plate, lower limit idler wheel is located at limit plate upper surface and the lower surface of hatch door beam structure and is formed by roller groove.
The axis of the lower limit idler wheel is parallel with the axis of upper crank idler wheel.
The transmission mechanism of the hatch door outdoor handle has the advantage that using the above structure
1. mechanism form is flexible, versatility is good: mechanism may be implemented vertical between right-hand side arbor and hatch door mechanism driving axis
Transmission, two axis can be arranged in same plane, can also according to hatch door other limitation require, between two axis there are
A certain distance；
2. stick control is good: mechanism may be implemented the movement from inside to outside of outdoor handle, operator can choose it is singlehanded or
Both hands are pulled outwardly outdoor handle, and handle is easy to operate, and force direction meets ergonomics；
3. mechanism driving is high-efficient: the cooperation of mechanism is the cooperation between idler wheel and roller groove, and rolling friction frictional force is small.
By adjusting the relative positional relationship between crank and idler wheel, can effective enlarging mechanism drive line angle, improve transmission efficiency；
4. intermittent movement may be implemented: by adjusting the shape of roller groove in two cranks, two axis are may be implemented in this set mechanism
Between intermittent movement.In the design of hatch door mechanism, there are big measuring mechanism timing control requirement, by this sets of transmission mechanism, synchronous control
Hatch door mechanism kinematic timing processed is the function that traditional mechanism cannot achieve.
