Detailed description of the invention
Here will be described exemplary embodiment in detail, its sample table shows in the accompanying drawings.When description below relates to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawing represents same or analogous key element.Embodiment described in following exemplary embodiment does not represent all embodiments consistent with the disclosure.On the contrary, they only with as in appended claims describe in detail, the example of apparatus and method that aspects more of the present disclosure are consistent.
Fig. 1 is the structural representation of a kind of aircraft according to an exemplary embodiment, as shown in Figure 1, by installing four propeller arrangements 2 for aircraft 1, thus passing through the rotation of these propeller arrangements 2, driving the flight operation of aircraft 1.Wherein, aircraft 1 is provided with the screw 11 corresponding with the rotating shaft of motor (not shown), and propeller arrangement 2 is matched by the outside thread of negative thread with this screw 11 surface, is finally mounted on this aircraft 1.Certainly, herein only for four-axle aircraft, but embodiment of the present disclosure can be applied in the aircraft of arbitrary form, and the disclosure does not limit this.
In order to configure negative thread on propeller arrangement 2, in correlation technique, propose multiple solution:
1, independent nut
As shown in Figure 2, in the related, the center of the propeller arrangement 2 manufactured is provided with through hole, then when propeller arrangement 2 is mounted to aircraft 1, screw 11 can stretch into, stretch out from top below this through hole, then by independent nut 3, tighten with screw 11 above through hole, complete the installation to propeller arrangement 2.
But because nut 3 and propeller arrangement 2 are separate, it is very inconvenient to make the dismounting of nut 3, especially out of doors when dismounting, is easy to cause the loss to nut 3.
2, embedded nut
As shown in Figure 3, in the related, when producing propeller arrangement 2, nut 3 can be embedded in bottom propeller arrangement, thus the problem solving nut 3 dismounting inconvenience, easily lose.But embedded for nut 3, needs to increase to propeller arrangement 2 step that " embedding " process, adds processing procedure and the cost of propeller arrangement 2.Meanwhile, in the telescopiny of nut 3, the accuracy requirement for embedded location is very high, probably impacts the balance of propeller arrangement 2; Or, need to increase special equipment, control the embedding precision to nut 3, but obviously need to increase corresponding significant cost.
Therefore, the disclosure passes through the improvement to propeller arrangement 2, to solve the above-mentioned technical matters existed in correlation technique.
Fig. 4 is the schematic diagram of a kind of propeller arrangement according to an exemplary embodiment, and as shown in Figure 4, this propeller arrangement 2 can comprise:
Body 21, and the blade 22 extended outward by body 21;
Wherein, the bottom of described body 21 caves inward, and forms negative thread 24 at the inwall of sunk area 23, and described negative thread 24 can make described propeller arrangement 2 be mounted on aircraft 1 (see Fig. 1, lower same).
In this embodiment, by forming negative thread 24 bottom the body 21 of propeller arrangement 2, make not need in propeller arrangement 2, adopt embedded metal nut 3 (see Fig. 2-3, form down together) obtains negative thread 24, and when propeller arrangement 2 is mounted to aircraft 1, do not need by means of other structures such as metal nuts 3 grade, contribute to promoting the positional precision of negative thread 24 on propeller arrangement 2, and reduce complexity and the manufacture difficulty of propeller arrangement 2 yet.
As an exemplary embodiment, the body 21 of propeller arrangement 2, blade 22 and negative thread 24 can be integral type structure; Wherein, by the mode of mold injection, above-mentioned integral structure can be formed.More known with the correlation technique shown in Fig. 2, in disclosed technical scheme, for the injection moulding manufacturing process of propeller arrangement 2, only need to produce screw thread on the mould used, can when not adding other treatment process and step, directly obtain the propeller arrangement 2 shown in Fig. 4 by injection moulding, thus do not need, when not needing to increase treatment step, negative thread 24 can be obtained; Meanwhile, the precision of negative thread 24 is relevant to the mould adopted, thus only need to control screw position on mould, can guarantee that propeller arrangement 2 has high-precision negative thread 24, and without the need to adopting precision controlling equipment required in Fig. 3 embodiment, not need to increase corresponding cost.
In addition, in embodiment of the present disclosure, propeller arrangement 2 can comprise along the symmetrically arranged at least one group of blade 22 of body 21, only comprises one group of blade 22 in such as Fig. 5.Wherein, the direction of negative thread 24 and the direction of tilt of blade 22 match, and make propeller arrangement 2 be mounted to the hand of rotation on aircraft 1 by negative thread 24, the hand of rotation under in running order with propeller arrangement 2 is consistent.
For example, in the embodiment shown in fig. 5, when propeller arrangement 2 realizes rotating counterclockwise along direction 1, negative thread 24 can be made to match with the outside thread on screw 11, propeller arrangement 2 is mounted on aircraft 1; Meanwhile, in working order, the blade 22 of propeller arrangement 2 also realizes along direction 1 rotating counterclockwise, thus in the flight course of aircraft 1, realizes the self-locking to propeller arrangement 2.And when propeller arrangement 2 realizes rotating clockwise along direction 2, propeller arrangement 2 can be separated with aircraft 1, realize the dismounting to propeller arrangement 2.Certainly, directions such as " cws ", " conter clockwise " herein, only for casehistory, the disclosure does not limit this.
Those skilled in the art, at consideration specification sheets and after putting into practice disclosed herein disclosing, will easily expect other embodiment of the present disclosure.The application is intended to contain any modification of the present disclosure, purposes or adaptations, and these modification, purposes or adaptations are followed general principle of the present disclosure and comprised the undocumented common practise in the art of the disclosure or conventional techniques means.Specification sheets and embodiment are only regarded as exemplary, and true scope of the present disclosure and spirit are pointed out by claim below.
Should be understood that, the disclosure is not limited to precision architecture described above and illustrated in the accompanying drawings, and can carry out various amendment and change not departing from its scope.The scope of the present disclosure is only limited by appended claim.
