When the solar blanket with the large flexible solar wings is compressed, as the fragile solar cell pieces are arranged in the solar blanket, the compression force in the solar blanket cannot be ensured by adopting the compression rod type compression release device, and the damage to the internal parts of the solar blanket is easily caused. 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 pressing-releasing mechanism is provided, which uses a two-stage loading mode to achieve a larger pressing force on the whole pressing-releasing mechanism, but only one pressing rod is used between the upper and lower plates of the mechanism to carry the pressing force of the whole device and perform one-way separation, which may result in unstable separation of the pressing-releasing mechanism due to a larger vibration amplitude during launching, and the mechanism selects the stress point as the central position, which may result in loosening and deviation of the pressing position of the solar carpet due to insufficient surrounding pressing force.
