The invention discloses a multi-connecting-rod auxiliary folding mechanism with a fixed sub-angle for a shipborne helicopter. The mechanism is composed of an empennage fixing side (1), an empennage folding side (2), a fixed sub-angle connecting rod (3), an auxiliary sub-angle connecting rod (4), a lead screw (5), a nut and motor driver (6), a guiding rod (7), a guiding sliding block (8) and a balancing spring (9), wherein all the components are connected through hinges; the other end of the guiding rod (7) is inserted into the guiding sliding block (8), so that a sliding pair is formed by the guiding rod (7) and the guiding sliding block (8); the balancing spring (9) is arranged between the guiding rod (7) and the guiding sliding block (8), so that a driving force in the folding process is reduced; the lead screw (6) is driven to extend or retract through the nut and the motor driver (6), so that a rotary angle between the empennage fixing side (1) and the empennage folding side (2) reaches 180 degrees. According to the multi-connecting-rod auxiliary folding mechanism with the fixed sub-angle for the shipborne helicopter, part of the hinges can be replaced by spherical pairs or sphere-pin pairs, so that an auxiliary folding spatial mechanism with the fixed sub-angle for the shipborne helicopter can be formed. The multi-connecting-rod auxiliary folding mechanism with the fixed sub-angle for the shipborne helicopter has the advantages that the structure is simple and convenient, the weight is light, and the time and labor force for folding operation can be greatly reduced.
