Document Type and Number:
WIPO Patent Application WO/2022/105042
Kind Code:
A1
Abstract:
An optical encoder assembly, composed of two parts, an encoder mechanical unit and a photoelectric unit. The encoder mechanical unit comprises a base (1) and a cover body (2). The photoelectric unit is a circuit board (4) attached with an optical module (3). The optical module (3) comprises a light-emitting element (31) and a photosensitive element (32). The encoder mechanical unit is combined with the photoelectric unit circuit board (4) by means of the base (1), and the encoder mechanical unit cooperates with the photoelectric unit to generate photoelectric signals. The present encoder uses an optical path module (51) having an innovative structure, and using a light-blocking turntable (5) matched with the optical path module (51) to achieve a change in the optical path. The present structure skillfully simplifies an optical path switch module, having a light and thin structure and a reasonable layout, while also saving costs. In addition, the light-blocking turntable (5) is further provided with a concave-convex surface (53), capable of cooperating with an elastic member (6) to provide a tactile feeling for the user. The present encoder assembly is compact in structure, fully utilized in space, easy to use, and suitable for mass production.
