The invention discloses a steering engine limiting structure which comprises a steering engine body, a gear reduction mechanism is arranged in the steering engine body and comprises an output gear used for installing a steering engine output shaft, and an auxiliary gear which is meshed with the output gear and does not participate in speed reduction is arranged in the steering engine body. An auxiliary gear is arranged in the steering engine body, an encoder for detecting the rotation angle of the auxiliary gear is arranged on the auxiliary gear, a limiting stop lever is further arranged on the auxiliary gear, a limiting column matched with the limiting stop lever is arranged in the steering engine body, a microswitch is arranged in the steering engine body, and a limiting rod matched with the limiting stop lever is arranged in the limiting column. A contact capable of triggering the microswitch is arranged on the output gear; the limiting angles of the microswitch, the encoder and the limiting column on the output gear are sequentially increased; by the adoption of the structure and the method, three-level limiting of the steering engine can be achieved in an electronic mode, a software mode and a mechanical mode, and then more reliable guarantee is provided for ensuring that the steering engine works within a reasonable angle range.

    本发明公开了一种舵机限位结构,包括舵机本体,所述的舵机本体内设置有齿轮减速机构,所述的齿轮减速机构包括用于安装舵机输出轴的输出齿轮,在所述的舵机本体内设置有与输出齿轮啮合且不参与减速的辅助齿轮,在所述的辅助齿轮上设置有检测辅助齿轮旋转角度的编码器,在所述的辅助齿轮上还设置有限位挡杆,在所述的舵机本体内设置有与限位挡杆配合限位柱,在所述的舵机本体内设置有微动开关,在所述的输出齿轮上设置有能触发微动开关的触点;所述的微动开关、编码器以及限位柱对输出齿轮的限位角度依次增大;采用上述结构和方法对舵机能够分别通过电子、软件以及机械方式实现三级限位,进而为确保舵机在合理的角度范围内工作提供更加可靠的保障。
