Further, continuing with referring to Figure 20-23, between first motor 61 and the first rotor 8 connection relation, For connection relation between second motor 62 and the second rotor 9, the embodiment of the present invention additionally provides a kind of Quick-dismantle component, is used for Quick Release connection between first motor 61 and the first rotor, between the second motor 62 and the second rotor 9.It realizes and is carrying out the first rotation When the wing 8, the installation of the second rotor 9 or dismantlement work, it is only necessary to by rotating first rotor 8 or second rotor 9, The fastening or separation between the first rotor 8 and first motor 61, between the second motor 62 and the second rotor 9 can be realized, Installation or the dismantlement work of the first rotor 8 can be completed without external operation tool (such as handle), have fast, just It takes and feature that operating efficiency is high.
Specifically, first motor 61 includes first surface 611 and second surface 612 in the present embodiment.In embodiment, First surface 611 can be understood as the upper surface of first motor 61, and second surface 612 can be understood as first motor 61 Lower surface, and the first motor 61 is fixed on by the first surface 611 on the first stationary plane of refrigerating seat 63, described Two motors 62 are fixed on by the second surface 612 on the second stationary plane of refrigerating seat 63.
It is significant to note that in the prior art for the multi-rotor unmanned aerial vehicle of coaxial double-oar, coaxial two Often diameter, shape are identical for a rotor, and positioned at the both sides up and down of rotor shaft, and the rotor above rotor shaft is revolving When turning, the air-flow for relying on its lower surface is needed to generate upward thrust to the rotor, then realize it is whole to unmanned plane to On lift.Obviously, the air-flow flow area of lower surface is bigger, then it is bigger to generate upward thrust to the rotor, then Realize that integrally upward lift is also bigger to unmanned plane.And exactly since two coaxial rotor sizes are identical, this is just So that the rotor of top and the rotor of lower section be during rotation, the rotor of lower section is due to the spatial area occupied by its own And most of air-flow flow area of top rotor lower surface is blocked, and it is then whole to reduce the upward lift of unmanned plane, it leads Cause flight efficiency low.
And in the present embodiment, it is by the horizontal axis centered on the rotor shaft, the first rotor 8 and the second rotor 9 is symmetrical Ground is distributed in the both sides of rotor shaft 2, and the diameter of the first rotor 8 is more than the diameter of the second rotor 9, realizes the first rotor 8 Whole size is more than the whole size of the second rotor 9, this allows for the process that the first rotor 8 and the second rotor 9 rotate at the same time In, the second rotor 9 is greatly reduced due to its own existing spatial area, to the air-flow stream of 8 its lower surface of the first rotor The obstruction of dynamic area, ensure that the air-flow of 8 its lower surface of the first rotor to thrust size upward caused by the rotor, then Also avoiding the whole lift upwards of unmanned plane reduces and influences the technological deficiency of its flight efficiency.With the high spy of flight efficiency Point.
For Quick-dismantle component 7, two Quick-dismantle components 7 can be selected so that first rotor 8 passes through a Quick Release Component correspondence is rotationally fixed in the first motor, and second rotor 9 is corresponded to rotationally by another Quick-dismantle component It is fixed on second motor.Since the first rotor 8 is by connection relation, the action principle of Quick-dismantle component 7 and first motor, It is identical with connection relation, the action principle of the second motor by Quick-dismantle component 7 with the second rotor 9, therefore, following implementations Example for being connect with first motor 61 by a Quick-dismantle component by the first rotor 8 only by being described in detail, the second rotor 9 It is repeated no more by the connection relation action principle between a Quick-dismantle component and the second motor 61, it can be together refering to following first Connection description between rotor 8 and first motor 61.
Specifically, during actual job, both the first rotor 8 and first motor 61 are threadedly coupled by Quick-dismantle component 7. So that during actual job when needing the first rotor to unmanned plane to be installed or dismantled, rotation institute is only needed The first rotor 8 is stated, such as rotates clockwise the first rotor 8 or counterclockwise the first rotor 8 of rotation, you can realize first rotor Installation or removal between 8 and the first motor 61.The first rotor 8 is directly fixed on the using bolt compared to traditional On one motor 61, when needing to dismantle the first rotor 8 from first motor 61, or installing, it is both needed to come by extraneous handle Bolt is turned, the disassembly and installation work of the first rotor 8 can be completed.And due to being used to connect the first rotor 8 and first motor 61 fixing bolt is the individual component of individualism, when turning bolt by handle and being unloaded, often due to scene behaviour Make the complexity of environment, easily cause the loss of fixing bolt, once and fixing bolt lose, then can not just complete the first rotor 8 and first motor 61 installment work, that is, the serious consequence for causing flight equipment that can not fly.And the present embodiment, it is exactly based on Both first rotor 8 and first motor 61 are threadedly coupled using Quick-dismantle component 7 so that the two is in installation or dismounting, nothing Fast and conveniently, need to have the characteristics that operating efficiency is high by external operation tool (such as handle).
For Quick-dismantle component 7, continuing with referring to Figure 21, the Quick-dismantle component 7 includes at least：First screw 71, the second spiral shell It follows closely the 72, first screw buckle 73 and first and dismantles nut 74.Wherein, the inner wall of first screw buckle 73 is provided with the first internal thread 76, and the bottom of first screw buckle 73 offers the first screw hole 77 so that first screw 432 passes through first spiral shell First screw buckle 73 is fixed on the first surface 611 of the first motor 61 by hole 77.The first dismounting nut 74 Outer wall be provided with first external screw thread 78 compatible with first internal thread 76, and the top of the first dismounting nut 74 Offer the second screw hole 79 so that second screw 72 sequentially passes through first rotor 8, second screw hole 79 will be described First dismounting nut 74 is fixed on first rotor 8.
Wherein, the first screw buckle 73 is fixed on by the first screw 71 on the first surface 611 of first motor 61, and first tears open Removing nut 74 is fixed on by the second screw 72 on the first rotor 8.And first screw buckle 73 inner wall opened up first in spiral shell The first external screw thread 78 for being opened up of outer wall that line 76 and first dismantles nut 74 exactly matches namely the first internal thread 76 and the Occlusion locking may be implemented between one external screw thread 78.It allows in this way, when needing the first rotor 8 being mounted in rotor shaft 3, Since first motor 61 is fixed on the end of rotor shaft 3, also the first rotor 8 is mounted in first motor 61.At this time, it is only necessary to The first rotor of manual rotation 8 so that the first external screw thread 78 is mutually engaged with the first internal thread 76, is continued to rotate, is then realized first The locking for dismantling nut 74 and the first screw buckle 73, since the first dismounting nut 74 is fixed on the first rotor 8, the first screw buckle 73 are fixed in first motor 61, namely realize the locking installation of the first rotor 8 and first motor 61 (rotor shaft 3).And work as It when needing dismounting, only needs to reversely rotate the first rotor 8 at this time, realizes that the separation of the first external screw thread 78 and the first internal thread 76 is It can.It is swift to operate, convenient to have the characteristics that.
It should be noted that unmanned plane, during practical flight, the direction of rotation of the first rotor 8 is rotation side counterclockwise To, at this point, due in flight course the first rotor 8 be to be in rotating state, and the first rotor 8 and first motor in itself Itself it is also the connection type that fastening is realized using rotation in embodiment between 61.For example, when the first rotor 8 is relative to first Motor 61 is when realizing fastening therebetween by rotating clockwise, since the normal of the first rotor 8 rotates to be in flight course Counterclockwise, there is the inverse time as the normal rotation counterclockwise of the first rotor 8 namely the first rotor 8 are equivalent to first motor 61 at this time The driving of needle rotation.And due to the first rotor 8 relative to first motor 61 be by rotate clockwise could realize therebetween Fastening, then it is on the contrary when it is to rotate counterclockwise the first rotor 8 occur relative to first motor 61, i.e., it can cause the first rotor Fastening relationships between 8 and first motor 61 loosen, and even result in the first rotor 8 and fly away from first motor 61 and cause nobody The phenomenon that machine crashes.
Therefore, in order to avoid unmanned plane in flight course the is caused due to the normal rotation counterclockwise of the first rotor 8 Fastening relationships between one rotor 8 and first motor 61 loosen, and the embodiment of the present invention is by the first rotor 8 and first motor 61 Between rotate the direction that the direction tightened is also configured to rotate counterclockwise.That is, set by the outer wall of the first dismounting nut 74 The occlusion locking direction of the first internal thread 76 set by the inner wall of first external screw thread 78 and the first screw buckle 73 is also counterclockwise Direction.It is allowed in this way when the first rotor 8 is to realize fastening therebetween by rotating counterclockwise relative to first motor 61, Since the normal of the first rotor 8 rotates to be counterclockwise in flight course, at this time with the normal rotation counterclockwise of the first rotor 8, Namely first rotor 8 be equivalent to first motor 61 also and have the tendency that rotating counterclockwise.
And due to the first rotor 8 relative to first motor 61 exactly by rotate counterclockwise could realize it is between the two Fastening, so on the one hand, effectively prevent ought the first rotor 8 relative to first motor 61 stung by rotating clockwise realization When closing locking, the fastening between the first rotor 8 and first motor 61 is caused due to normal rotate to be counterclockwise of the first rotor 8 Relationship loosens, even result in the first rotor 8 fly away from first motor 61 and cause unmanned plane crash technological deficiency.Another party Face, since the first rotor 8 is also that could realize fastening between the two by rotation counterclockwise relative to first motor 4 itself, When the normal rotation counterclockwise with the first rotor 8, and the first rotor 8 is made to be equivalent to first motor 61 also and have rotation counterclockwise Trend, just also increase 61 fastening relationships between the two of the first rotor 8 and first motor at this time, ensure that flight equipment Normal safe flight has the characteristics that security performance is high.
