As previously described and referring to attached drawing, cantilever 3 and fuselage junction are provided with cantilever mounting structure 11, wherein with it is electronic The fuselage connection of unmanned plane is first part 111；Connecting with the cantilever 3 of electronic unmanned plane is second part 112；First Cantilever shaft 113 is fixedly connected on part 111, second part 112 can be around cantilever shaft 113 with respect to 111 turns of first part It is dynamic；It is spring bearer plate 114 that second part 112, which is stuck in first part 111,.

Second part 112 is the cylinder-like structure for the outer diameter that internal diameter is greater than cantilever 3, and the root of cantilever 3 is inserted in second Divide in 112 and is fixedly connected by screw.The cantilever 3 of the application and the second part 112 of cantilever mounting structure 11 pass through tubular Structure carries out grafting, can obtain bigger contact area and obtain bigger frictional force, be connected firmly and be easy to connect by screw It connects and dismounts, high reliablity, the operation such as maintenance easy to disassemble.

2-3 is further elaborated with the specific knot of the cantilever mounting structure of the electronic unmanned plane of the application with reference to the accompanying drawings Structure, wherein beating for the cantilever mounting structure of the electronic unmanned plane of another specific embodiment according to the application is shown in Fig. 2 Open state schematic diagram；The cantilever installation knot of the electronic unmanned plane of another specific embodiment according to the application is shown in Fig. 3 The dismantling status diagram of structure.

Especially as shown in figure 3, unlike the prior art, in the application, second part 112, which is provided with, rides over cantilever turn Hook 201 on axis 113, hook 201 are stretched out from second part 112 and are prolonged towards the direction opposite with spring bearer plate 114 It stretches, hook 201 can take off from cantilever shaft 113 after second part 112 rotates an angle around cantilever shaft 113 It opens.When the operation such as daily maintenance of electronic unmanned plane, it is only necessary to which pressing 114 rear end of spring bearer plate makes spring bearer plate 114 Front end lift, can be disengaged by the upper end for the second part 112 that spring bearer plate 114 blocks, around 113 turns of cantilever shaft Dynamic second part 112, so that second part 112 rotates certain angle, state as shown in Figure 2.Then lift obliquely upward with The connected second part 112 of cantilever 3, hook 201 can be disengaged from the state for being overlapped on cantilever shaft 113, as shown in Figure 3 State.

It will be appreciated by those skilled in the art that in relation to the angular dimension that second part 112 rotates, it is downward with hook 201 The length and angle of extension and dependency structure size are related, for example, cantilever shaft 113 center with respect to hook 201 distance Deng, those skilled in the art specific embodiment disclosed with reference to the accompanying drawings, it is easy to the principle based on Machine Design, for not sympathizing with Part dimension under condition obtains the angular dimension that second part 112 needs to rotate, and obtains on the basis of present disclosure Specific angular dimension needed for obtaining is apparent to those skilled in the art, and this is no longer going to repeat them.

In the cantilever fold mechanism of the prior art, cantilever shaft, which interts first part and second part, to link together, It needs to remove cantilever shaft when dismantling cantilever.In view of the purpose for avoiding disengaging, cantilever shaft needs grafting Must be very secured, therefore dismount cantilever shaft needs and take some time.And in the cantilever mounting structure of the application, cantilever turns Axis 113 is fixed in first part 111, when dismounting cantilever 3, is completely dispensed with and is loosened cantilever shaft 113, it is only necessary to pine The upper end of the second part 112 blocked by spring bearer plate 114 is opened, then rotates second part 112, so that it may lift second part 112 will remove with entire 3 slave of cantilever, easy to operate compared with the prior art, quick, and only need in the prior art On the basis of, the auricle for the second part being originally fixed in cantilever shaft is removed, the hook 201 for being changed to the application can With, it is small to the change of existing structure, it can greatly save and design and manufacture cost.

Further, spring bearer plate 114 is arranged in first part 111, is provided on second part 112 and spring bearer plate 114 corresponding clamps 115.Spring bearer plate 114 can press its rear end under external force opens its front end, then utilizes The elastic force of spring (may refer to the dependency structure in 107600385 A of CN), which is closed downwards, tangles clamp 115, to be formed Together with snapping relationship snaps connection first part 111 with second part 112, state shown in Fig. 1 is formed.It is outstanding when needing to dismantle When arm 3, the rear portion of spring bearer plate 114 is equally pressed under external force, the front end of spring bearer plate 114 is opened, will hang Arm 3 pushes so that second part 112 is rotated around cantilever shaft 113, and clamp 115 is detached from snapped-in position, and cantilever mounting structure 11 is complete It is complete to open, state shown in Fig. 2 can be formed.

That is, second part 112 is by way of clamping on the whole in the above-mentioned specific embodiment of the application It is connected in first part 111.Wherein, the clamp 115 of second part 112 and hook 201 are respectively by corresponding Spring bearer plate 114 and cantilever shaft 113 are stuck in first part 111.More specifically, the clamp 115 of second part 112 and The spring bearer plate 114 of a part 111 forms clamping structure, fixes in the hook 201 of second part 112 and first part 111 The cantilever shaft 113 of connection forms clamping structure.Spring bearer plate 114 is blocked clamp 115 by structures such as springs, and can be led to It crosses pressing spring bearer plate 114 and discharges clamp 115.

Hook 201 and clamp 115 form contrary flanged structure, and hook 201 rides over cantilever shaft 113 On.In the case that clamp 115 is blocked by spring bearer plate 114, entire second part 112 is firmly blocked not by first part 111 It can loosen.After spring bearer plate 114, which lifts, releases clamp 115, rotation second part 112 can be obliquely by hook 201 remove from cantilever shaft 113, so as to take off with the cantilever being connected with second part 112 3 on the whole slave , the simply easy-disassembling-assembling quick-disassembly structure of structure is formd, in order to be applicable in the rapid application of military domain, can needed When whole cantilevers are disassembled overhauled, replaced, transported.

In a further advantageous embodiment, the limit stretched out there are two being arranged in first part 111 towards second part 112 Piece 118, the width position that two limit films 118 correspond to clamp 115 is arranged, and the spacing between two limit films 118 is greater than The width of clamp 115.The present embodiment is greater than the limit film 118 of the width of clamp 115 by two spacing of setting, can formed After buckle status shown in FIG. 1, clamp 115 is limited between two limit films 118, so as to further prevent second Left and right displacement of the part 112 along 113 length direction of cantilever shaft.That is, the limit film 118 being arranged through this embodiment, can hinder Only first part 111 and second part 112 slide laterally dislocation, further improve the connection jail of the fold mechanism of the application Solidity, it is ensured that will not be loosened due to dislocation, will not therefore increase reinforcing weight, and 118 structure of increased limit film Very little will not influence the connection of spring bearer plate 114, will not influence the connection reliability of fold mechanism.

Further, the upper surface of spring bearer plate 114 is provided with a locking spiral shell button 102, to by spring bearer plate 114 with First part 111 is removably joined together, and can fix spring bearer plate 114 prevents its rotation, avoids in vibration or nothing Making spring bearer plate 114 in the case where the touching of consciousness, surprisingly release causes the accident disconnected with 3 slave of cantilever to occur, and provides The reliability of mechanism.

Just as described in the background section, there is cantilever disassembly difficulty, this Shen in the existing electronic unmanned plane of multiaxis Please provide can fast quick-detach cantilever mounting structure, but also bring another technical issues that need to address simultaneously. Since electronic unmanned plane is difficult to accomplish holosymmetric structure, and load layout will also result in center of gravity asymmetry, therefore each outstanding The motor installed on arm requires to be calibrated one by one for full machine center of gravity, lift situation, and the flight control system of electronic unmanned plane is deposited Contain the motor adjustment data of different location.Flight control system can set different control signals for the motor of different location, use To coordinate the lift balance of complete machine, while the parameters such as the revolving speed of the motor of different location, pitch can be coordinated, control is entire electronic Heading, flying height of unmanned plane etc..

The application can be to disassemble due to using quick-disassembly structure, entire cantilever completely with slave.When needs will be torn open When the cantilever unloaded down reinstalls on fuselage, it is accordingly required in particular to pay attention to the cantilever of different location being correctly installed to original Come position, once position setup error, unmanned plane one starting will disequilibrium cause air crash.Due to the electronic unmanned plane of multiaxis Cantilever it is numerous, and the general appearance of each cantilever is almost identical, is difficult to differentiate in appearance, therefore especially needs to worry The problem of installation error.

A kind of feasible scheme is in cantilever and the corresponding installation site setting identification label of fuselage.But when maintenance Markd part may will be applied to replace；Frequently dismounting can also to mark smudgy；Night or light are bad In the case of be possible to identification mistake.These problems can all cause the mode of setting identification label not to be especially reliable.And reality In the case of there is also operator's sense of responsibility not enough, awareness of safety lacks, in emergency circumstances non-expert start-up operation is asked Topic does not have the effect for preventing setup error even if being provided with identification label is only ornaments at all.Therefore, the application mentions A kind of cantilever Anti-misplug mechanism without especially training, having reliable Anti-misplug function is gone out.

4-6 is further elaborated with the specific of the cantilever Anti-misplug mechanism of the electronic unmanned plane of the application with reference to the accompanying drawings Structure, wherein the cantilever Anti-misplug mechanism of the electronic unmanned plane of a specific embodiment according to the application is shown in Fig. 4 Decomposition state schematic diagram；The assembled state schematic diagram of second part in Fig. 4 is shown in Fig. 5；Fig. 6 is shown in Fig. 4 elastic The assembly decomposition state schematic diagram of pressing plate.

Referring to fig. 4-6, the cantilever Anti-misplug mechanism of the electronic unmanned plane of the application is a kind of to be installed with to avoid by cantilever To the mechanism of the fuselage positions of mistake；Cantilever Anti-misplug mechanism includes that the fuselage above-mentioned with electronic unmanned plane is connect A part 111；The second part 112 being connect with the cantilever 3 of electronic unmanned plane；The cantilever being fixedly connected in first part 111 Shaft 113, second part can be rotated around cantilever shaft 113 relative to first part 111；And second part 112 is stuck in Spring bearer plate 114 in a part 111, the setting of spring bearer plate 114 are connected in first part 111, are arranged on second part 112 There is clamp 115 corresponding with spring bearer plate 114, to illustrate already before the specific structure of upper-part, repeats no more.Such as Fig. 4- 6 are shown in detail, and multiple mounting holes 1151 are provided on clamp 115, and multiple and 1151 position of mounting hole is provided on spring bearer plate 114 Corresponding slot 1141；The protrusion 1152 of pluggable slot 1141 is selectively installed in mounting hole 1151；Slot 1141 In correspond to be fitted without protrusion 1152 position be provided with prevent protrusion 1152 be inserted into slot 1141 filler 1142.

The following detailed description of the basic functional principle of the cantilever Anti-misplug mechanism of the application.

When the production and processing of product parts, on the clamp 115 of all production and processings, all it has been pre-machined multiple Mounting hole 1151, the quantity of visible mounting hole 1151 is 5 in specific embodiment in Fig. 4.Meanwhile in the bullet of all production and processings On property pressing plate 114, slot 1141 identical with 1151 quantity of mounting hole, visible slot 1141 in Fig. 6 has also been pre-machined Quantity be also 5.That is, the clamp 115 on each cantilever is with 5 mounting holes when production and processing 1151, it is also with 5 slots 1141 on each spring bearer plate 1141, this is for the ease of arranging mass production, drop Low production cost reduces production process.

When different cantilevers 3 is installed to corresponding position on fuselage, it is provided with first of spring bearer plate 114 111 are divided to be mounted on fuselage, the second part 112 for being provided with clamp 115 is mounted on cantilever 3.At this point, for area The installation site of not each cantilever 3, can be as shown in Figure 5, selects in the mounting hole 1151 of the leftmost side of clamp 115 two Middle installation protrusion 1152, it is corresponding, the position setting three for being fitted without protrusion 1152 can be corresponded in slot 1141 A filler 1142 for preventing protrusion 1152 to be inserted into slot 1141.

So, when installing cantilever 3, as Figures 5 and 6 cooperate, without the two of filler 1142 A slot 1141 be it is empty, can just allow two protrusions 1152 on clamp 115 to be inserted and cooperate.This is cantilever 3 situations that should occur when being installed to correct position.

And if it is by mistake cantilever 3 installation position shown in fig. 6, then the card of the second part 112 on cantilever 3 The position of two protrusions 1152 on first 115 is not just at least one in two protrusions 1152 as shown in Figure 5 Position be dislocation, and misplace this corresponding spring bearer plate 114 of protrusion 1152 on slot 1141 in be to be equipped with Filler 1142.So, when installation, the protrusion 1152 of dislocation, which can not be just inserted into, is equipped with filler 1142 Slot 1141 in, thus cantilever 3 cannot be normally carried out and be mounted with, avoid the generation of cantilever wrong plug, improve cantilever peace The safety of dress.

Since 5 mounting holes 1151 being pre-machined on clamp 115, if two protrusions of installation as shown in Figure 5 Object 1152 theoretically has 10 kinds of different combinations, thus can guarantee that the mounting structure of 10 cantilevers 3 is all different 's.Certainly, likewise, corresponding to this 10 kinds of structures, in 5 slots 1141 on spring bearer plate 114,3 fillers are filled 1142 combination is also 10 kinds, can just correspond to the different cantilever 3 of 10 kinds of structures of installation.Therefore, shown in Fig. 4-6 The mounting hole 1151 of specific embodiment and the quantity of slot 1141 can be adapted for using in the electronic unmanned plane of 10 axis and 10 axis or less In the structure for uniquely distinguishing all cantilevers 3.

For the electronic unmanned plane of more multiaxis, the mounting hole 1151 of preprocessing and the quantity of slot 1141 can be increased.Example Such as, if there are 6 mounting hole 1151 and 6 slots 1141 respectively, 3 protrusion 1152 and 3 fillers 1142 are set, then most 20 kinds of combinations can be mostly provided.And if there is 7 mounting hole 1151 and 7 slots 1141 respectively, 3 protrusions are set 1152 and 4 fillers 1142, then can at most provide 35 kinds of combinations, can substantially cover existing multiaxis it is electronic nobody The limit quantity of the cantilever of machine.Certainly, if only 4 mounting hole 1151 and 4 slots 1141, are arranged 2 protrusions 1152 and 2 fillers 1142 then at most only have 6 kinds of combinations, are also suitable for 6 axis and 6 axis electronic unmanned plane below ?.

Certainly, it will be understood by those skilled in the art that the quantity of mounting hole 1151 and slot 1141 can also be different, the peace having more The quantity of dress hole 1151 or slot 1141 can be used as reserved extended use, temporarily unavailable.Such as the mounting hole having more Temporarily protrusion 1152 is not installed in 1151, just thinks that the mounting hole having more is not present；And temporarily pacify in the slot 1141 having more Filler 1142 is filled, also just thinks that the slot 1141 having more is not present.It is, of course, preferable to mounting hole 1151 and slot 1141 Quantity is identical, and operation error is avoided to bring unnecessary trouble.

It is further preferred that the structure of all slots 1141 is identical, the structure of all protrusions 1152 is identical； The structure of all fillers 1142 is identical.Such benefit is can to reduce the quantity of components, improves the logical of part Adaptation issues with property, correlated parts are few, are conveniently adjusted processing, the packaging efficiency that can be reduced production cost, improve product.

By the description of the above-mentioned cantilever Anti-misplug mechanism of the application, those skilled in the art can also should further be sent out Existing, this cantilever Anti-misplug mechanism of the application not only can be adapted for the cantilever shown in attached drawing 1-3 with quick releasing function and pacify It in assembling structure, is readily applicable in the mounting structure of the electronic unmanned plane of the foldable cantilever of the prior art, can prevent from hanging Cantilever position setup error when reinstalling after arm assembly or maintenance avoids the fuselage position that cantilever is installed to mistake It sets, improves the safety of cantilever installation, avoid the generation of air crash accident.

In conclusion the cantilever Anti-misplug mechanism of the electronic unmanned plane of the application passes through in multiple mounting holes on clamp Selectivity installation protrusion, the mounting structure of each cantilever can be distinguished one by one, cooperate corresponding on spring bearer plate insert Slot corresponding can allow the cantilever of each different mounting structures to be uniquely installed to the correct position on fuselage, can prevent from hanging Cantilever position setup error when reinstalling after arm assembly or maintenance avoids the fuselage position that cantilever is installed to mistake It sets, improves the safety of cantilever installation, avoid the generation of air crash accident.
