With characteristics such as impact resistances, there is compared with Other Engineering plastics significant advantage, can be used for high-end machinery and aviation etc.
The materials such as sciemtifec and technical sphere alternative metals and pottery.Many rotor wing unmanned aerial vehicles support arm folding machine that this utility model provides
Structure, its body part 1, an arm-piece 2 and rotating shaft 3 use PEEK cast one-shot forming, are in many rotations
Wing unmanned plane field uses PEEK material to carry out structural member processing and manufacturing first, have lightweight, structure is strong
The advantages such as degree height is low with difficulty of processing.Therefore, this utility model structure is light, and intensity is high, and can be quick
Casting, it is simple to mass production, low cost.
As another embodiment of the present utility model, as it is shown on figure 3, described arm-piece 2 with body part
1 end connected is provided with revolving part 21, and this revolving part 21 offers through hole 22, correspondingly, body
Also offer through hole 14 on part 1, rotating shaft 3 through through hole 22,14, thus by the end of body part 1 and
The end propping up arm-piece 2 is flexibly connected.Preferably, described revolving part 21 is triangular in shape, and through hole 22 is positioned at this
The apex of triangle rotating part 21, to improve the flexibility of revolution of an arm-piece 2.
As a preferred embodiment of the present utility model, described body part 1 is at the end being connected with an arm-piece 2
The bottom in portion is provided with the first locating part 11, and the top of this end is provided with the second locating part 12, and described
One locating part the 11, second locating part 12 is used to limit the angle between described body part 1 and an arm-piece 2
Size.It can be seen that described first locating part 11 and the second locating part 12 can be controlled from Fig. 1 and Fig. 2
Angle when body part 1 processed launches with an arm-piece 2 and folds.Preferably, described first locating part 11 court
Arching upward in the other end body part 1, described second locating part 12 protrudes from body part 1, and described
Second locating part 12 arches upward away from the direction of the first locating part 11.It should be noted that first is spacing
The shape that arches upward of part the 11, second locating part 12 preferably keeps consistent, to increase limit with the profile of an arm-piece 2
Body part 1 and arm-piece 2 stability during position.It is further preferable that described first locating part 11 and the second limit
Position part 12 is connected by arc connector 13, connects increasing by first locating part the 11, second locating part 12
Fastness, also can improve globality and the activity stability of this fold mechanism simultaneously.
As shown in Figures 2 and 3, in another embodiment of the present utility model, described protruding block 5 is positioned at
The top of the second locating part 12, this protruding block 5 is in mountain font.The middle part of this mountain font protruding block 5
For projection, both sides are lower slightly, can effectively catch on described hook 4.
As it is shown on figure 3, in another embodiment of the present utility model, described hook 4 include coupler body 41,
Fixing groove 43, torsion spring 42 and torsional axis 44, described fixing groove 43 is fixed on the top of an arm-piece 2, turns round
Spring 42 is positioned at this fixing groove 43, and described torsional axis 44 passes fixing groove 43, torsion spring 42 and coupler body 41,
Thus coupler body 41 is covered in the outer surface of fixing groove 43.Preferably, described coupler body 41 is near body
The end of part 1 offers draw-in groove 45 (head), when coupler body 41 mutually catches on protruding block 5, protruding
Block 5 passes in draw-in groove 45, to improve the clamping fastness of coupler body 41 and protruding block 5.
Coupler body 41 has elastic force under the effect of torsion spring 42 and makes coupler body 41 head keep tightening up state,
Arm-piece 2 be deployed into close to when 0 ° can, coupler body 41 head contacts with the protruding block 5 on body part 1,
Thus by coupler body 41 head jack-up (torsion spring 42 is compressed), continue to launch an arm-piece 2 until reaching 0 °,
Now due to the elastic force of torsion spring 42, coupler body 41 head tangles protruding block 5 by automatically recovering the state of tightening up, from
And automatically by locked, as shown in Figure 1 for an arm-piece 2.When packing up, press coupler body 41 afterbody, the most releasably
Prop up arm-piece 2 and be folded down, as shown in Figure 2.Traditional many rotor wing unmanned aerial vehicles are the most collapsible, although
The design of some structures is collapsible but its fold mechanism uses frame structure of aluminum alloy to realize, and needs and carbon fiber pipe
Carry out card band tightener, and its locking mechanism needs instrument or artificial unloading.And the hook in this utility model
4 can be automatically by locked for an arm-piece 2, this hook automatic locking device relying on hook 4 structure to realize,
The folding body rapid deployment of many rotor wing unmanned aerial vehicles can be realized, very useful convenient.
As can be seen here, the support arm fold mechanism that this utility model provides has the advantage that structure is light, intensity
High；Quick cast molding, it is simple to mass production, low cost；Unfolded is convenient, be not required to instrument；Hang
Hook is automatically locked support arm, and development rate is fast.
