Illustrate the purpose of the utility model embodiment.
It please refers to Fig.2 a to Fig. 2 d, in the embodiment of the present application, is shown for being configured with the rotor mechanism of two panels blade
Example property explanation, but it will be understood by those skilled in the art that the rotor mechanism of greater number blade is also in the protection model of the utility model
In enclosing.
First as shown in Figure 2 a, a kind of rotor mechanism, is primarily adapted for use in unmanned plane, including paddle seat 11 and two panels blade
12.When the rotor mechanism is maintained at the horizontal attitude that Fig. 2 a are illustrated, which can realize in a rotating manner
Horizontal folding.
And then for arbitrary a piece of blade 12, as shown in Figure 2 c, set on the blade 12 there are two blind hole 13, this two
13 coaxial setting of blind hole.Here, one of blind hole 13 is because of viewing angle problem, not showing in figure 2 c, but this field skill
Art personnel should understand the relative position of two blind holes 13 on the basis of present specification disclosure.In the present embodiment
In, it is specifically set in the root of blade 12 there are one cylindrical structure, two end faces of the cylindrical structure process that there are one blind holes respectively
13。
In the embodiment of the present application, as shown in Figure 2 d, mounting groove 14 there are two being set on the paddle seat 11, it should be appreciated that installation
The quantity of slot 14 is consistent with the quantity of blade 12, and a mounting groove 14 allows a piece of blade 12 to be inserted into, such as the blade
12 cylindrical structure is inserted into mounting groove 14.Selectively, the height phase of the height of the mounting groove 14 and foregoing cylindrical structure
Cooperation, and the height of mounting groove 14 is slightly larger than the height of cylindrical structure, to limit the movement of blade 12.
Wherein, for any one mounting groove 14：A connecting shaft 15, and the connecting shaft 15 are equipped in the mounting groove 14
For segmental structure, specifically it is divided into the first part 151 of interruption setting and second part 152.During practical set, such as Fig. 2 b institutes
Show, the first part 151 is inserted into a blind hole 13 of blade 12 (blind hole 13 and first part 151 in a manner of mobilizable
For clearance fit, the aperture of blind hole 13 is more than the diameter of first part 151), while the second part 152 is also with mobilizable
Mode is inserted into another blind hole 13 of blade 12 that (blind hole 13 and second part 152 are clearance fit, and the aperture of blind hole 13 is more than
The diameter of second part 152), the connection of blade 12 and paddle seat 11 is just realized in this way, and the blade 12 also is able to around connection
Axis 15 rotates.It should know, in order to highlight the structure of connecting shaft 15 in Fig. 2 a and Fig. 2 b, by the first part of connecting shaft 15
151 and second part 152 shown with hatching so that those skilled in the art can clearly know connecting shaft 15 with
The assembly relation of blind hole 13.In addition, Fig. 2 b are the partial enlargement in region indicated by dotted line frame in Fig. 2 a.
In the embodiment of the present application, the blade 12 is preferably process with one-shot forming technique, and the paddle seat 11 is also
It is made with one-shot forming technique, later, the paddle seat 11 forms connecting shaft 15 preferably through in-mould injection technique, i.e. paddle seat 11 passes through
It crosses post forming and is configured to the structure being integrated with connecting shaft 15.Particularly, during paddle seat 11 undergoes post forming,
The connecting shaft 15 is just combined with two blind holes 13 of blade 12.Blade 12, paddle seat 11 and connecting shaft 15 are passed through into mould at this time
The interior disposable assembling of injection is completed, and assembly technology is simple, and it is good to assemble effect.
However, the mode that the application includes but not limited to in-mould injection realizes that blade 12, paddle seat 11 are same with connecting shaft 15
When assemble, as long as can be extended to form in the mounting groove 14 of paddle seat 11 for be inserted into blind hole 13 and segmentation connecting shaft 15, and
Other processing methods that connecting shaft 15 is quickly and easily connected with blade 12 also are able to, also in the protection domain of the application
Within.
Further, in order to avoid in-mould injection causes blade 12 harmful effect, the connecting shaft 15 and blade 12
Material selected as differs, and connecting shaft 15 is identical with the material of paddle seat 11, it is preferred that the paddle seat 11 and the material of connecting shaft 15
Matter is nonmetallic, such as plastic parts, it is furthermore preferred that the material of the connecting shaft 15 is selected from the high plastic material of wearability.It is described
Blade 12 is also preferably in the present embodiment plastic parts, light weight.
Further, in one embodiment of the application, the first part 151 and second part 152 are cylinder
Body, and the first part 151 is identical with the diameter of second part 152 but length may be selected to differ.In other of the application
In embodiment, the first part 151 and second part 152 are cylinder, and the first part 151 and second part
152 diameter and length be disposed as it is identical, molding it is more convenient.
In the present embodiment, shape and the connecting shaft 15 of the blind hole 13 match, if the blind hole 13 is processed as circle
Hole, the aperture of two blind holes 13 is identical but depth may be selected to differ, alternatively, the aperture of two blind holes 13 and depth
It is set as identical.Furthermore it is preferred that whole length of the first part 151 and second part 152 are inserted into corresponding blind hole 13
Middle cooperation.
In addition, the embodiment of the present application also provides a kind of unmanned plane, the unmanned plane includes rotor mechanism as described above, and
