6. a kind of single power source single-point locking three-level wing synchronous unfolding device as claimed in claim 5, it is characterised in that described same
Walking component (5) includes a secondary synchronization bar (5a), two three-level synchronizing bars (5b) and synchronous pin (5c),
The one secondary synchronization bar (5a) is elongate rod structure, and two ends are provided with through hole, and two ends pass through synchronous pin (5c) point respectively
It is not hinged with pedestal (1a) and two grades of bars (3a), in this way, makes a secondary synchronization bar (5a), pedestal (1a), one-level bar (2a)
Be hinged with two grades of bars (3a) as a parallelogram, the parallelogram power torsion spring (1d) the lower expansion of moment of torsion effect, with
The synchronous expansion of one-level bar assembly (1) and two grades of bar assemblies (2) is realized,
Two three-level synchronizing bars (5b) are also elongate rod structure, and two ends are provided with through hole, the two ends respectively with one-level bar (2a) and pull bar
(4a) is hinged, with realize three-level stroke amplifier module (4) and one-level bar assembly (2), two grades of bar assemblies (3) synchronous expansion,
Lock hole is provided with the one secondary synchronization bar (5a), for realizing that mechanism is locked with locked component (6) cooperation.
7. a kind of single power source single-point locking three-level wing synchronous unfolding device as claimed in claim 6, it is characterised in that the lock
Determining component (6) includes compression spring (6a) and locking step guide finger (6b),
Compression spring (6a) is located in the blind hole on pedestal (1a), and locking step guide finger (6b) is located at the blind hole on pedestal (1a)
Outside,
In expansion motion process, locking step guide finger (6b) is spacing by secondary synchronization bar (5a) end face, in retraction
State,
When expansion moves to ultimate position, the positioning hole opened up on a secondary synchronization bar (5a) and locking step guide finger (6b)
Alignment, locking step guide finger (6b) stretches out under compression spring (6a) effect, and locking step guide finger (6b) is same with one or two grades
The lock hole of step bar (5a) coordinates the locking for realizing a secondary synchronization bar (5a),
Compression spring (6a) is in compressive state, and power is provided for the axial movement for locking step guide finger (6b).
