Description

Mechanism for increasing integral clamping load of solar carpet

Technical Field

The invention relates to the technical field of solar wing pressing and releasing devices, in particular to a mechanism for increasing the integral clamping load of a solar carpet.

Background

At present, the compression and release device of the domestic solar wing spreading mechanism mostly adopts a compression rod type compression and release mode, is similar to a screw tightening and fixing object, the tightening force of the compression rod type compression and release device directly acts on a compression point, only the compression force of the compression point can be controlled, and the compression force in a compressed object is determined by the self structural characteristics of the compressed object. When the solar blanket with the large flexible solar wings is compressed, the fragile solar cell pieces are arranged in the solar blanket, and the compression release device adopting the compression rod type cannot ensure the compression force in the solar blanket, so that the internal parts of the solar blanket are easily damaged. Meanwhile, the high compression level between the external box plates of the solar blanket is ensured, so that the solar blanket is prevented from being loosened due to impact during launching and losing the support and protection of the solar blanket.

In chinese patent publication No. CN105253331B, a force-limited compressing and releasing mechanism is provided, which uses a two-stage loading mode to achieve a larger pressing force on the whole compressing and releasing mechanism, but only one pressing rod is used between the upper and lower plates of the mechanism to bear the pressing force of the whole device, which may result in unstable separation of the compressing and releasing mechanism due to a larger vibration amplitude during launching, and the mechanism adopts a zigzag structure, resulting in waste of lateral used space.
