Description
Technical field
The present invention relates to propulsion system technical field, be specifically related to a kind of reclining device.
Background technology
Dirigible a kind ofly has propelling and the aerostatics of flight control unit, with regard to its structure, generally include be filled with helium hull, be positioned at gondola below hull, play the empennage of stability contorting effect and the propulsion system of power is provided.Dirigible because of its good reliability and safety, and can carry out the feature of spot hover, is widely used in current taking photo by plane, surveys and draws, in the field such as advertisement.
In recent years, along with the enhancing of common people's environmental consciousness and the progress of electronic Push Technology, and the arrival of advection layer altitude research boom, electronic dirigible becomes the focus of current dirigible field of research.Current electronic dirigible, its flying speed is lower, and for improving the handling under its low speed, so in current design, its propulsion system is all the vector propeller adopting band reclining device usually.
In current electronic dirigible structure, vector propeller is generally two, be arranged in the both sides of gondola respectively, reclining device is then placed in gondola inside, and the structure of reclining device mainly includes motor, driving device, the axis that is simultaneously in transmission connection with two vector propellers, is carrying out in manipulation process, stepping motor is rotated by actuator drives axis, axis synchronously drives two vector propellers be attached thereto, and so, realizes synchronously verting to two vector propellers.
In current reclining device structure, axis stage casing is by arranging bearing or other strut members support, the end, two ends of axis is connected with a vector propeller respectively, like this realization coordinates the vector propeller that both ends are arranged that verts, such as Chinese patent application " the high altitude region electric power unwrapping wire Powered Propulsion assembly of electronic dirigible " (number of patent application: CN201220311406.8), it discloses a kind of Powered Propulsion assembly for electronic dirigible, include Linkage steering, propulsion electric machine is connected with at the two ends of Linkage steering, the propulsion electric machine at two ends is driven to rotate the adjustment realizing direction of propulsion by Linkage steering, such as Chinese patent application " Helium Airship duct inclining rotary mechanism " (number of patent application: CN201320012062.5) again, it discloses a kind of Helium Airship duct inclining rotary mechanism, comprise worm couple, for the motor driving the worm screw of this worm couple to rotate, the worm gear of this worm couple is arranged on duct axle, a duct circle is respectively equipped with at duct axle two ends, described motor is connected with driving device worm screw through coupler, described duct circle is built with Helium Airship propelling unit, in this application, worm screw drives worm gear wheel, worm gear drives propelling unit again, such as Chinese patent application " a kind of gravity-center adjustable airship gondola " (number of patent application: CN201320360328.5) again, the propulsion system involved by it is the two ends being arranged on screw mandrel, coordinates the propulsion system of rotating two ends by the rotation of screw mandrel.
Although the reclining device of said structure is used in current dirigible structure widely, find after follow-up study careful for a long time present inventor, the reclining device essence of said structure also exists unavoidable defect, and reason is:
In above-mentioned reclining device, no matter be Linkage steering, worm screw, screw mandrel or axis, its effect is all for making propelling unit realize verting, then simple beam structure is formed between its structure itself and actuating device or bracing or strutting arrangement, the angle of rake weight in two ends is completely by Linkage steering, worm screw, screw mandrel or axis carrying, and, Linkage steering, worm screw, screw mandrel or axis need to run through whole gondola completely and can realize being connected with two propelling units simultaneously, make Linkage steering, worm screw, screw mandrel or axis are all in slender rod piece structure, the single supported beam of this slender rod piece structure is less along the load-carrying capacity in crossbeam radial direction, rigidity is also less, and also there will be the concentrated situation of stress in support place, specific in dirigible field, be embodied in following several aspect:
(1), because load-carrying capacity is less, rigidity is also less, so can only be applicable to the little and lightweight propelling unit of power, seriously limits high-power angle of rake use, and then limits the development of high-power airship technology;
(2), under actual applying working condition environment, dirigible is taking off, when flight or landing, whole dirigible more or less all can be impacted unavoidably, and the reclining device of simple beam structure, its Linkage steering, worm screw, screw mandrel or axis are all slim-lined construction, rigidity is low, impact resistance is weak, and then when impact occurs as easy as rolling off a log because of impact bending, once Linkage steering, worm screw, screw mandrel or axis occur bending, the control being just difficult to obtain again coordinating of verting of its two ends propelling unit, so, make the reliability of dirigible and handling all poor, serious potential safety hazard is brought to the use of dirigible,
(3), with regard to the structure of above-mentioned reclining device, owing to having an elongated connecting rod, worm screw, screw mandrel or axis between two propelling units, and hull itself is the structure of sealing, so when propelling unit is arranged on hull both sides, above-mentioned reclining device is also inapplicable, so also limit the Applicable scope of reclining device.
So, based on above-mentioned technical matters, need one at present badly and neither limit propelling unit model and power, various dirigible structure can be applicable to again, and also there is good reliability and handling reclining device.
Summary of the invention
The object of the invention is to, for current reclining device above shortcomings, provide one neither to limit propelling unit model and power, various dirigible structure can be applicable to again, and also there is good reliability and handling reclining device.
To achieve these goals, the technical solution used in the present invention is:
A kind of reclining device, includes the actuating device driving the tiliting axis of propelling unit generation pitch motion and drive described tiliting axis to rotate, the corresponding described propelling unit of described tiliting axis.
In the such scheme of the application, the reclining device provided, essence is each reclining device only corresponding propelling unit, need to carry two propelling unit weight compared to traditional reclining device simultaneously, be first alleviate the weight that reclining device carries, improve the reliability of reclining device, and, also make the reclining device of the application can load capacity larger, the propelling unit that power is higher, what so realize high-power propelling unit to apply to airship technology field may;
Simultaneously, also just because of each reclining device only corresponding propelling unit, the reclining device of the application can be arranged according to angle of rake actual design position, and the relative position relation between each propelling unit need not be considered, significantly increase the Applicable scope of reclining device;
