The invention provides an unlocking mechanism, an undercarriage and an operation method. The unlocking mechanism comprises a shell, an emergency valve, a thermal control valve, a coordination valve and a main valve, the emergency valve, the thermal control valve, the coordination valve and the main valve are arranged in the shell, a port A and a port B communicated with the port A are formed in one end of the shell, a port E and a port D communicated with the port E are formed in the other end of the shell, a port C is further formed in the shell, and a port D is formed in the other end of the shell. The emergency valve axially displaces to close or communicate the port A and the port B, the coordinating valve axially displaces to communicate or close the port C, the outside of the coordinating valve and the port B, the thermal control valve is arranged in the coordinating valve, and the thermal control valve axially displaces along the coordinating valve to communicate or close the port C, the inside of the coordinating valve and the port B; and the main valve axially displaces to communicate or close the port B, the outside of the coordinating valve and the port C. An existing hydraulic control locking mechanism is improved, the space layout is optimized, and the emergency unlocking function is added.

    本发明提供一种开锁机构、起落架及运行方法。所述开锁机构包括外壳和设于所述外壳内的应急活门、热控活门、协调活门和主活门,所述外壳的一端设有A口和与所述A口连通的B口,所述外壳的另一端设有E口和与所述E口连通的D口,所述外壳上还设有C口,所述应急活门轴向位移以将所述A口和B口关闭或连通,所述协调活门轴向位移以将C口、协调活门外部和B口连通或关闭,所述热控活门置于所述协调活门内,且所述热控活门沿所述协调活门轴向位移以将所述C口、协调活门内部和B口连通或关闭,所述主活门轴向位移以将B口、协调活门外部和C口连通或关闭。本发明改进现有液控锁定机构,优化空间布局,增加应急开锁功能。
