Specific embodiment

It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

Fig. 1 is the attachment structure schematic diagram of the mounting structure for propeller that the utility model embodiment one provides and motor.Fig. 2 It is the partial structural diagram of the mounting structure for propeller in Fig. 1.Fig. 3 is the propeller peace that the utility model embodiment one provides The connection structure front view of assembling structure and motor.Fig. 4 is the partial structural diagram of mounting structure for propeller in Fig. 3.Fig. 5 is this The connection structure side view of mounting structure for propeller and motor that utility model embodiment one provides.Fig. 6 is the utility model reality The mounting structure for propeller of the offer of example one and the connection structure top view of motor are provided.As shown in Figures 1 to 6, the present embodiment provides Mounting structure for propeller, for propeller to be detachably arranged in motor 10.The mounting structure for propeller specifically includes Mounting base 1, locking piece 2 and elastic component 3；Mounting base 1 is fixed on the end face of motor 10, and mounting base 1 passes through the electricity of motor 10 Arbor 20, mounting base 1 is used for and propeller rotation engaging, and elastic component 3 and locking piece 2 connect, and elastic component 3 is used for along motor shaft 20 axial direction applies elastic force to locking piece 2, so that locking piece 2 is at least partly blocked on the outside of the engagement direction of propeller.

Specifically, mounting structure for propeller is implemented for the company between propeller and the motor 10 of unmanned vehicle It connects.The motor 10 of unmanned vehicle can drive propeller rotational, and such propeller can produce upward lift when rotating, because And unmanned vehicle can be driven to realize flight and landing operation.In general, unmanned vehicle can have multiple propellers, thus Correspondingly, mounting structure for propeller generally can also have multiple, and the quantity phase of the quantity of mounting structure for propeller and propeller Together.

In order to drive propeller rotational, motor 10 generally includes stator, rotor and motor shaft 20 etc., wherein motor shaft 20 It can be stretched out from a side end face of motor 10.In general, motor shaft 20 can be fixedly connected with the side end face on motor 10, in this way End face on motor shaft 20 and motor 10 can be rotated relative to 10 ontology of motor, and propeller can be installed by propeller Connection is realized between structure and the rotatable end face of motor 10, and the end face is followed to rotate together.Motor 10 and spiral in this way More reliable power transmission structure is capable of forming between paddle, to adapt to biggish driving moment or higher revolving speed.

It wherein, in order to which propeller to be installed on motor 10, and is dismountable connection type between motor 10, specifically , it include the mounting base 1 being fixed on 10 end face of motor in mounting structure for propeller, and be flexibly connected with mounting base 1 The structures such as locking piece 2 and the elastic component 3 being located in mounting base 1 for driving locking piece 2 to support.Wherein, mounting base 1 is fixed on motor On 10 end faces, thus when the end face rotation of motor 10, mounting base 1 can also be rotated synchronously, to drive propeller to rotate.Mounting base 1 Generally hollow structure, such mounting base 1 can pass through the motor shaft 20 of motor 10 and be fixed on motor 10, make motor shaft 20 The outside of mounting base 1 can be extend out to and propeller is positioned, at the same do not influence motor 10 motor shaft 20 rotation with And power transmission.In addition, in order to fix propeller, it is usually provided with the structures such as protrusion or card slot in mounting base 1, and can be with Engaging is rotated between propeller.In this way by way of rotation engaging, propeller can be from being axially fixed on motor 10.

At work, its own can follow the rotation of mounting base 1 under the drive of motor 10 and synchronize and turned propeller Dynamic, when the revolving speed of propeller is too fast, propeller is possible to be detached from from the position engaged with mounting base 1, to cause to penetrate paddle Phenomena such as, influence the normal flight and safety of unmanned vehicle.And in order to avoid propeller is de- from the position engaged with mounting base 1 From, further include in mounting structure for propeller have locking piece 2 and elastic component 3, and by elastic component 3 elastic force and allow locking piece 2 to support It connects can be on the position of sealed propeller.

Specifically, since mounting base 1 is generally hollow structure, thus locking piece 2 mutually nested with mounting base 1 can be set It sets, e.g. locking piece 2 is arranged in the hollow cavity of mounting base 1 or locking piece 2 is also hollow structure, and is disposed around The outside of mounting base 1.Due to being provided with the structure that can rotate engaging with propeller of protrusion or card slot in mounting base 1, because And relative displacement may be implemented between locking piece 2 and mounting base 1, to be moved to the position with protrusion or the same axial height of card slot It sets, in this way when the snap-in structure of propeller is fixed in mounting base 1 by way of rotation engaging, locking piece 2 can pass through The structure of itself and keep off the outside in protrusion or card slot so that the snap-in structure of propeller is locked part 2 and is stopped, and nothing Method is detached from from the position engaged with protrusion or card slot, so that locking of propeller is completed propeller and installation in clamped position It is relatively fixed between seat 1.

Wherein, locking piece 2 can generally be moved along axial realize of motor shaft 20, so that gear is outside protrusion or card slot Side and the position of locking screw paddle；Either be moved to from protrusion or the different axial position of card slot and release to propeller Limitation locking.When locking piece 2 is located at the different axial positions with protrusion or card slot, at this point, due to convex in mounting base 1 Rise or the outside of card slot do not have locking piece 2 to be blocked, it is thus possible to normally with the snap-in structure revotating card of propeller It closes, or is detached from and engages between the snap-in structure of propeller.Wherein, in order to allow locking piece 2 can freely in motor shaft The movement relative to mounting base 1 is realized in 20 axial direction, and the knot such as groove or evacuation cavity usually can be set in mounting base 1 Structure, to avoid locking piece 2, recurring structure is interfered between mounting base 1 when moving.At this point, locking piece 2 can pass through groove or Person avoids cavity, and along motor shaft 20 radially across in the two sides of mounting base 1, thus mounting base 1 opposite sides simultaneously Realize locking.

Under normal conditions, locking piece 2 should maintain the position for capableing of the snap-in structure of locking screw paddle, so that propeller It is maintained at clamped position, avoids the snap-in structure of propeller from being detached from mounting base and engages.At this point, usually can use elastic component 3 Elastic force by locking piece 2 keep in the position.Specifically, since locking piece 2 is relied on from the movement in 20 axial direction of motor shaft Change the limit state to propeller, thus the elastic force direction of elastic component 3 also can be along the axial direction of motor shaft 20, e.g. court To the direction for deviating from motor side face.Locking piece 2 can be abutted by the elastic force of elastic component 3 or is fixed in mounting base 1 in this way Propeller engagement direction outside, thus allow propeller be locked part 2 be limited in the position being mutually clamped with mounting base 1, And it can not deviate from from the clamped position.

Wherein, due to being rotation engaging between mounting base 1 and propeller, thus the engagement direction of propeller can be along motor The circumferential direction of 10 motor shafts 20, and it is opposite with the direction of rotation of the rotor of motor 10.In this way when elastic component 3 applies elastic force, Elastic component 3 can make locking piece 2 along the axial movement of motor shaft 20 by own resilient, and locking piece 2 is moved along the axial direction of motor shaft 20 It moves to suitable position, the outside along itself direction of rotation of propeller will be blocked in, to allow propeller can not be from the party Engage to the disengaging of mounting base 1.It is connected by way of rotary clamping between propeller and mounting structure for propeller in this way, one Aspect connection is more reliable, is on the other hand also convenient for carrying out the dismounting and replacement operation of propeller.In general, elastic component 3 can be with It is positioned close to the position of 1 central part of mounting base, is e.g. coaxially disposed with motor shaft 20, also can be set close to installation The position of rotation snap-in structure on seat 1.

Optionally, in order to realize rotation engaging with mounting base 1, generally equally have on propeller and mounting base 1 is adapted Clamping structure, and be normally at the propeller hub position of propeller.Propeller can use the clamping structure of itself and realize in this way Rotation between mounting base 1 engages.

In mounting structure for propeller, locking piece 2 positions propeller from the circumferential direction of propeller, thus spiral Paddle can be mounted seat 1 and locking piece 2 is fixed on the position that connection is mutually clamped with mounting base 1 jointly.Thus propeller can be with End face relative to motor 10 is fixed, and when motor 10 rotates, propeller can be rotated with it, while guarantee that inherently safe is reliable Be fixed on motor 10.

Specifically, in order to be connected on motor 10, while rotation engaging completed to propeller, mounting structure for propeller can be with With a variety of different structure types, it is specifically described in detail below.

Optionally, mounting base 1 can be the annular element for being disposed around the outside of motor shaft 20, and mounting base 1 is circumferentially arranged There is at least one first holding part 11, the first holding part 11 is used for and propeller rotation engaging.

Specifically, since mounting base 1 is annular element, thus the motor shaft 20 of motor 10 can be from the sky in 1 center of mounting base Between pass through, and mounting base 1 usually has inner wall or outer wall in a ring, and the clamping structure of such propeller is similarly annular When, the circumferential direction sliding relative to motor shaft 20 can be realized and inner wall with mounting base 1 or outer wall contact, in this way, edge At least one holding part that mounting base 1 is circumferentially arranged can realize that rotation engages between propeller, or under fastening state It rotationally disengages.

Common, since mounting base 1 is annular element, and propeller can be contacted by inner wall with mounting base 1 or outer wall And circumferentially slide, thus as an alternative embodiment, the first holding part 11 can be outwardly protruded in the outer of mounting base 1 Wall.At this point, the clamping structure on propeller can be disposed around the outside of the mounting base 1 of annular, 1 outer wall of mounting base is protruded from this way First holding part 11 can be realized with the clamping structure in outside and is clamped.In the present embodiment, installation is protruded from the first holding part 11 It is illustrated for the outer wall of seat 1.

And as another optional embodiment, the first holding part 11 can the inwardly projecting inner wall in mounting base 1. At this point, mounting base 1 is disposed around the outside of the clamping structure of propeller, and clamping is realized between the clamping structure of inside.Thus Correspondingly, the second holding part can also protrude from the inner wall of mounting base 1, and the clamping knot for being located at 1 inside of mounting base with propeller Structure realizes clamping.

In order to when rotating engaging with propeller, improve the load ability of mounting base 1, the quantity of the first holding part 11 is logical It often can be more than one, at least two first holding parts 11, and at least two first e.g. can be set in mounting base 1 The setting of the interval of holding part 11.For mounting base 1 when realizing rotation engaging, multiple first holding parts 11 can be in mounting base 1 in this way Different parts realize limit engaging to propeller, and 1 stress of mounting base is more dispersed when engaging, it is thus possible to bear biggish power Square.

Optionally, when the first holding part 11 is multiple, multiple first holding parts 11 can be relative to the axis of motor shaft 20 To the setting that is centrosymmetric.In this way connection of the mounting base 1 between realization and propeller when, torque can uniformly be passed to Each first holding part 11 keeps stress of the mounting base 1 in circumferential all directions more balanced, improves the knot of mounting base 1 Structure reliability.

When the first holding part 11 is multiple, since the mode engaged between mounting base 1 and propeller for rotation realizes company It connects, thus for the ease of allowing propeller circumferentially smoothly to rotate relative to mounting base 1, as an alternative embodiment, All first holding parts 11 can be respectively positioned on the sustained height along axial direction of mounting base 1.Due to the equal position of all first holding parts 11 In on the sustained height of mounting base 1, such first holding part 11 can be collectively formed in the circumferential direction of mounting base 1 positioned at sustained height Snap-latch surface.Propeller and mounting base 1 can realize opposite sliding and be rotated by the snap-latch surface, be mutually clamped with turning to Position.

As one of optional snap fit, there can be the snap-in structure along itself radially protruding on propeller, and Correspondingly, can form the first card slot 111 of the circumferentially extending along mounting base 1 on the first holding part 11, the first card slot 111 is used for It rotates and engages with snap-in structure.

Specifically, snap-in structure on propeller can along the radially outward or inwardly projecting of propeller, and correspondingly, The first holding part 11 in mounting base 1 also the inwardly projecting inner wall in mounting base 1 can be outwardly protruded either in mounting base 1 therewith Outer wall.And the first card slot 111 circumferentially extended along mounting base 1 can be formed on the first holding part 11, the first card slot 111 Extending direction and propeller it is axially vertical, thus the snap-in structure of propeller can be moved to transmission shafts upwards with The position that mounting base 1 is overlapped, and rotates snap-in structure, is caught in snap-in structure in the first card slot 111, and with the first card slot 111 Between realize engaging.

In general, the first card slot 111 can circumferentially surround on a certain axial position on the outside of motor shaft 20, and using certainly Snap-in structure on propeller is also limited at the position relative to motor shaft 20 by body cell wall.In addition, on the first card slot 111 Stop configurations are generally also provided with, when being in this way that the snap-in structure of propeller moves rotation along the first card slot 111, can be existed by backstop Relative in a certain circumferential angle of mounting base 1, to realize the positioning to propeller in the axial direction.

It optionally, can on the first different holding parts when the quantity of the first holding part 11 is two or more Various sizes of first card slot is arranged.Illustratively, the size of the first card slot 111 is different, can be the outer of the first card slot 111 Edge or inner edge radius difference etc..In this way when the snap-in structure on propeller is installed on mounting structure for propeller, due to One card slot 111 can engage with snap-in structure, thus various sizes of first card slot can also correspond to the engaging knot for being connected to propeller Various sizes of part on structure.Various sizes of first card slot can be allowed to be located at not according to the rotation direction difference of propeller in this way With direction and position, when the rotation direction mistake of propeller, e.g. positive paddle (CW) and for installing anti-paddle (CCW) propeller peace Assembling structure engage when, just can not with each first card slot, 111 snap-fit, to play foolproof function.

Common, the first card slot 111 can be unidirectional card slot, and the side of extending direction is notch, and extending direction The other side is the slot bottom for backstop snap-in structure.After the snap-in structure of propeller is protruded into from the notch of the first card slot 111 in this way, It can be slided along the extending direction of the first card slot 111, until being abutted with the slot bottom of the first card slot 111.

In addition, when the quantity of the first holding part 11 is only two, the first card slot 111 or two-way card slot, at this point, First holding part 11 and the first card slot 111 are only used for constraining propeller along 20 axial direction of motor shaft, and utilize locking Part 2 constrains propeller in motor shaft 20 in the radial direction.

Wherein, optionally, the first card slot 111 can have diversified forms and structure.For example, the first card slot 111 can have There is bilateral cell wall, alternatively, the first card slot 111 can also only include side cell wall, and other position limiting structures is utilized to limit propeller Axial position relative to mounting base 1.

In a kind of optional structure type, the first card slot 111 includes the first rib on the first holding part 11 1111, the first rib 1111 is circumferentially extended along mounting base 1, when propeller and the rotation of the first card slot 111 engage, the first rib 1111 are located at the side of the separate motor 10 of snap-in structure.

In this way, the first rib 1111 can form the side cell wall of the first card slot 111, when propeller and the first card slot 111 When rotation engaging, the first rib 1111 can be blocked in the side of snap-in structure, to avoid propeller together with snap-in structure from the side It is detached from.Thus the first rib 1111 can with the other structures relative to the snap-in structure other side, e.g. motor 10 or peace Snap-in structure is clipped in wherein by the structure on dress seat 1 jointly, to limit the snap-in structure position upward in transmission shafts.
