The invention discloses a gear structure for a steering angle sensor, the steering angle sensor is used for detecting the steering angle of a steering column, the steering column comprises a shell and a steering shaft, the steering column comprises a sensor base, the sensor base is arranged in the shell, a first gear is arranged in the sensor base, and the first gear can be fixed on the steering shaft; the gear assembly is arranged in the sensor base, the gear assembly is meshed with the first gear in the radial direction of the first gear, the gear assembly is connected with an angle sensor, and the angle sensor is used for detecting the rotation angle of the gear assembly. The first gear capable of being fixed with the steering shaft of the steering column and the gear assembly meshed with the first gear are arranged in the same sensor base, so that on one hand, the distribution of the gear assembly in the radial space can be reduced, and on the other hand, the mounting precision of the gear assembly and the sensor base can be improved; and thus, the rotation angle measurement result of the steering column is more accurate.

    本发明公开了一种用于转角传感器的齿轮结构,转角传感器用于检测转向管柱的转角,转向管柱包括壳体以及转向轴,包括:传感器底座,传感器底座设于壳体内,传感器底座内设有第一齿轮,第一齿轮可固定于转向轴;齿轮组件,齿轮组件设于传感器底座内,齿轮组件沿第一齿轮的径向与第一齿轮啮合,齿轮组件上连接有角度传感器,角度传感器用于检测齿轮组件转动的角度。本发明通过将可与转向管柱的转向轴固定的第一齿轮以及与第一齿轮啮合的齿轮组件均设置于同一个传感器底座内,一方面能够减小齿轮组件在径向空间的分布,另一方面可以提高齿轮组件以及传感器底座的安装精度,进而使得转向管柱的转角测量结果更加准确。
