Embodiment
The embodiment of the disclosure is described in detail below in conjunction with accompanying drawing.It should be appreciated that this place is retouched
The embodiment stated is merely to illustrate and explained the disclosure, is not limited to the disclosure.
As Figure 1-5, the present invention provides a kind of hatch door lifting servomechanism, provides power-assisted for hatch door, including turn
The dynamic torsion stock 1 being connected on hatch door door body width between two frames, the side of the torsion stock 1 is arranged with first
Sleeve 3, opposite side are arranged with second sleeve 7, and the torsion stock 1 is connected with the first sleeve 3 and second sleeve 7 passes respectively
Pass torsional load；First Rocker arm 4 is set on first sleeve 3, the free end of first Rocker arm 4 and the one of screw tube 5
End rotation connection, the other end of the screw tube 5 are set in one end of screw rod 6；The other end of the screw rod 6 is rotationally connected with cabin
On the beam of door door body；Second rocking arm 8 is set in the second sleeve 7, and this example is set in close to the end of torsion stock 1, and described the
The other end of two rocking arms 8 is rotationally connected with one end of connecting rod 9, and one end of the other end of connecting rod 9 and the 3rd rocking arm 10 is rotatablely connected,
The other end of 3rd rocking arm 10 is set in lift shaft 11, and the both ends of the lift shaft 11 are individually fixed in hatch door door body
On frame.
Further, the two ends of the torsion stock 1 are respectively equipped with spline 2；First sleeve 3 and second sleeve 7
The side inwall coordinated with the spline 2 is equipped with spline, and torsional load is transmitted for coordinating with the spline 2；Specifically, institute
The two ends for stating torsion stock 1 are milled with spline 2 respectively, such as can increase in the two ends diameter of torsion stock 1, and in increase portion
Position mills out six tooth splines 2；The wherein side of the torsion stock 1 is arranged with the first sleeve 3, first sleeve 3 and the flower
The side inwall that key 2 coordinates is provided with spline, for coordinating with the spline 2 to transmit torsional load；The torsion stock 1 it is another
Side is arranged with second sleeve 7, and the side inwall that the second sleeve 7 coordinates with the spline 2 is provided with spline, for institute
State spline 2 and coordinate transmission torsional load.
Hatch door provided in an embodiment of the present invention lifts servomechanism, when installing first, when hatch door completely closes, passes through
Adjusting screw rod 6 is rotated, the first Rocker arm 4 of driving is rotated to produce moment of torsion around the first sleeve 3, and the moment of torsion is delivered to torsion by spline 2
Power stock 1, then second sleeve 7 is delivered to by the spline 2 of opposite side, being output to connecting rod 9 eventually through the second rocking arm 8 forms axle
Power, connecting rod 9 drives the trend that the 3rd rocking arm 10 promotes lift shaft 11 to produce rotation, so as to form lifting pretightning force, the machine
Structure just completes installation；Handle is connected (transmission mechanism and lifting in hatch door by the transmission mechanism in hatch door with lift shaft 11
Axle 11 is existing hatch door internal structure), so, when each hatch door is opened, lifting power-assisted can be provided by the mechanism, gently
Pine completes the unlatching of hatch door.When hatch door is opened, lifting power-assisted is provided by the mechanism, is easily accomplished the unlatching of hatch door.This
Embodiment is provided with hatch door lifting servomechanism merely with door body self structure, without departing from door body scope, takes up space small, and
Simple in construction only with mechanical means, cost is cheap, and reliability is high.
In a kind of embodiment of the present embodiment, the both ends of the torsion stock 1 pass through the first set respectively
Cylinder 3 and second sleeve 7 are rotationally connected with the frame of door body, specifically, such as sleeve can be set on frame, respectively by first set
In sleeve on one end of cylinder 3 and one end insertion frame of second sleeve 7, so as to form rotation connection；According to specific cabin door structure
The difference of arrangement, link position can differences.
It should be noted that in the present embodiment, the lifting power-assisted that hatch door is opened is from the pre- of hatch door lifting servomechanism
Clamp force, the weight of hatch door determines the size for needing pretightning force, and the size of pretightning force depends on the torsional rigidity of torsion stock,
Torsional rigidity is together decided on by the length and cross-sectional area (i.e. diameter) of torsion stock, and when diameter is identical, torsion stock is longer,
Torsional rigidity is smaller, otherwise bigger；The timing of length one, diameter is bigger, and torsional rigidity is bigger, otherwise smaller；In the present embodiment,
For the ease of installing the hatch door hoisting mechanism of this programme, the length that torsion stock 1 can be set is a little, for example, can select torsion
Stock through whole door body width and be connected on two frames of door body, so, can torsional rigidity as needed pass through
Calculate and obtain the suitable torsion stock of diameter.
It should be noted that the first Rocker arm 4 and the second rocking arm 8 be because associated mechanisms to be driven move, therefore will to space
Ask of a relatively high, therefore to be selected the correct position on the length direction of torsion stock 1 to carry out according to the concrete structure of hatch door
Installation, that is, the length of the first sleeve 3 and second sleeve 7 is respectively depending on and the first Rocker arm 4 and the second rocking arm are set on hatch door
8 locus, and the length of sleeve can arbitrarily be set, it is relatively low to space requirement, it is often depending on two rocking arms 8 and
The position of one Rocker arm 4, for example, the first Rocker arm 4 is close to one end of torsion stock 1, the first sleeve 3 is just short sleeve, the second rocking arm 8
Close to the centre position of torsion stock 1, second sleeve 7 is long sleeve；The length of second sleeve 7 is approximately equal to torsion length in this example
The half of bar 1.
In another embodiment of the present embodiment, the other end of the screw rod 6 can pass through sleeved mount
12 are fixed on the beam of hatch door door body, are rotatablely connected between the screw rod 6 and sleeved mount 12；For example, can be by screw rod 6
The other end is fixed on the side bar of torque arm bottom.
In another embodiment of the present embodiment, the both ends of the lift shaft 11 are rotated by sleeve respectively to be connected
It is connected on the frame of hatch door door body；Specifically, sleeve can be set on the frame of door body respectively, and the both ends of lift shaft 11 are inserted
Into sleeve, so as to form rotation connection.
The preferred embodiment of the disclosure is described in detail above in association with accompanying drawing, still, the disclosure is not limited to above-mentioned reality
The detail in mode is applied, in the range of the technology design of the disclosure, a variety of letters can be carried out to the technical scheme of the disclosure
Monotropic type, these simple variants belong to the protection domain of the disclosure.
It is further to note that each particular technique feature described in above-mentioned embodiment, in not lance
In the case of shield, it can be combined by any suitable means.In order to avoid unnecessary repetition, the disclosure to it is various can
The combination of energy no longer separately illustrates.
