Condition understands the concrete meaning of above-mentioned term in the present invention.
As Figure 1-Figure 4, a kind of fold mechanism, including position-restricted housing 1 and movable housing 2；The position-restricted housing 1 wraps
Include limiting plate 110, locking unit 120 and the pressing component 130 that two structures are identical and are oppositely arranged；
The movable housing 2 includes two position-limiting ears 210 being oppositely arranged, and two position-limiting ears 210 have card
Socket part 211, the movable housing 2 be located at described two limiting plates 110 being oppositely arranged between, the movable housing 2 with it is described
Limiting plate 110 is be hinged to be set；
The opposite side of two limiting plates 110 has chute 111, and the type of the chute 111 includes half and sealed
Enclosed chute 111, groove etc., the locking unit 120 include pretension part 121 and sliding axle 122；The pretension part
121 include elastic component 121A and lead 121B, the lead 121B in the chute 111, the sliding axle 122
Both ends be sheathed on respectively on two lead 121B, the elastic component 121A is sheathed on the lead 121B, institute
State elastic component 121A one end and the sliding axle 122 is connected the pretightning force produced towards the Access Division 211；The pressing
Part 130 is located at the middle part of the sliding axle 122；
User drives the sliding axle 122 described in the interior edge of chute 111 by pressing the pressing component 130
Chute 111 moves away from the Access Division 211 so that and the sliding axle 122 departs from the fixed relationship with the Access Division 211,
So that the relatively described position-restricted housing 1 of the movable housing 2 rotates along jointed shaft, that is, complete jackknife action.At the same time,
The elastic component 121A, forced compression produce deformation generation and press pressure elastic force in opposite direction, terminated in user
The pretension part 121 is enabled to automatically reset after pressing, convenient operation, it is preferred that the elastomeric element uses compression spring.
The sliding axle 122 is " the locking shape described in the present embodiment when being in fastening state with the Access Division 211
State "；When the fold mechanism is in the locking state, two chutes 111 are apart from described 211 nearlyer one end of Access Division
Level height is identical, two chutes 111 are higher than the Access Division 211 apart from described 211 nearlyer one end of Access Division, pass through
The arrangement of this difference in height so that elastomeric element supplies the sliding axle 122 towards the pretightning force of the connecting portion, and exemplified below three
Kind " two level heights of chute 111 are apart from described 211 nearlyer one end of Access Division and the level height of Access Division 211 " difference in height
The example of arrangement mode, the arrangement mode of the present embodiment is explained：
" when the fold mechanism is in the locking state, two chutes 111 are apart from the clamping for arrangement mode one
The level height of 211 nearlyer one end of portion is less than the level height of the Access Division 211 ", in this case, due to the chute
The limitation of 111 height, the pretightning force of the elastic component 121A can not break height limitation, cause locking effect not firm,
In unmanned plane high-altitude flight, easily vibrate, cause to fly crooked.
" when the fold mechanism is in the locking state, two chutes 111 are apart from the clamping for arrangement mode two
The level height of 211 nearlyer one end of portion is equal to the level height of the Access Division 211 ", in this case, although compared with the first
The supply of pretightning force is relatively firm for situation, but is also only limitted in a kind of relatively steady state (such as static placement).
" when the fold mechanism is in the locking state, two chutes 111 are apart from the clamping for arrangement mode three
The level height of 211 nearlyer one end of portion is higher than the level height of the Access Division 211 ", i.e. the present embodiment is by the way of, at this
In the case of kind, pass through the arrangement of this difference in height so that elastomeric element supplies the sliding axle 122 towards the connecting portion always
Pretightning force, avoid the generation of Vibration Condition so that overall structure is more stable.
Other has a kind of special circumstances here：" both ends of two chutes 111 apart from the Access Division 211 away from
From identical ", in this case, the either end of chute 111 distance is higher than the Access Division 211.
To meet the difference of the present embodiment difference in height while make it that the overall structure of fold mechanism is more preferably compact, when the folding
When folded mechanism is in locking state, level height of two chutes 111 apart from described 211 nearlyer one end of Access Division is identical,
Level height of two chutes 111 apart from described 211 nearlyer one end of Access Division is higher than the level height of the Access Division 211
0.5-5mm, in above-mentioned number range, to ensure that the size of pretightning force suitably preferably uses 1-2mm spans.
In the present embodiment, the position-limiting ear 210 further comprises limited block 212, and the limited block 212 is used for by described in
Sliding axle 122 is limited in the Access Division 211, is prevented when the elastomeric element aging, pretightning force failure, it is difficult to maintain card
Connect action, there is provided a kind of urgent protection structure；Specifically, the limited block 212 is located at the madial wall of the Access Division 211
On, the limited block 212 is located at the opening of the Access Division 211.
The both sides of the limited block 212 are inclined-plane in the course of the sliding axle 122 for convenience, this inclined-plane
Design do not obstruct movement of the sliding axle 122 in the chute 111 while meeting spacing, and in pressing process
In add pressing touch.
A kind of unmanned plane, including spider 3, some horns 4 and above-mentioned fold mechanism, some horns 4 are uniform
The edge of spider 3 is distributed in, the fold mechanism is located between some horns 4 and the spider 3.By in nothing
The man-machine upper increase fold mechanism so that folding part keeps stable in state of flight.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements done etc., should be included within the scope of protection of the invention with principle.
