Actuator casing

摘要

A casing configured for receiving a motor. The motor includes a shaft, two end plates substantially perpendicular to the shaft, and two bosses respectively protruding from the two end plates along the shaft. The casing includes two abutting plates. Each abutting plate includes an arcuate resisting surface that substantially faces the other abutting plate for abutting against a corresponding end plate. The distance between the two resisting surfaces increases from the middle thereof to the side thereof. Each abutting plate comprises a notch formed in an edge thereof and extending along the middle of the corresponding resisting surface for receiving a corresponding boss.

1. A casing, configured for receiving a motor that comprises a shaft, two end plates substantially perpendicular to the shaft, and two bosses respectively protruding from the two end plates along the shaft, the casing comprising:
two abutting plates, each abutting plate comprising an arcuate resisting surface that substantially faces the other abutting plate for abutting against a corresponding end plate, a notch formed in an edge thereof and extending along the middle of the corresponding resisting surface for receiving a corresponding boss, and lateral ends disposed on opposite sides of the corresponding resisting surface, wherein the distance between the two resisting surfaces increases from the middle to the lateral ends of the resisting surfaces of the abutting plates, an arc of the resisting surface is formed between the lateral ends thereof, and the casing further comprises
a bottom plate, wherein the two abutting plates extend from the bottom plate, anda protrusion protruding from the resisting surface of an abutting plate, the top end of the protrusion is equal to or below the bottom of the corresponding notch, and the protrusion comprises an arcuate surface that substantially faces the other abutting plate.
