Self-adaptive structure, charging gun head and charging mechanical arm

The invention provides a self-adaptive structure, a charging gun head and a charging mechanical arm, and the self-adaptive structure comprises a fixed seat, a guide block which is in butt joint with a charging seat for guiding, a lip-tongue structure which is arranged on the guide block and is used for being connected with the charging seat in a clamping manner, and a plurality of self-adaptive driving parts, the guide block is provided with an inclined guide face used for making contact with the charging base, the moving end of each self-adaptive driving piece is movably connected with the guide block, and the fixed end of each self-adaptive driving piece is fixed to the fixed base. According to the self-adaptive structure, the charging gun head and the charging mechanical arm provided by the invention, the guide block can be adjusted to a position and a posture which can be directly matched with the charging base by controlling the expansion and contraction amount of each self-adaptive driving piece. Thus,
