  • Optical element driving mechanism having movable portion for holding lens
    Patent number: 11982866
    Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

  • Cooling fan module having functionality of blocking reverse flow of hot air and a host electronic system having the same
    Patent number: 11224142
    Abstract: A cooling fan module includes a fan unit and an air flow blocking unit. The air flow blocking unit includes a left-side plate, a left-side support pole, a left-side air flow blocking plate, a right-side plate, a right-side support pole, a right-side air flow blocking plate, and a stop member. The left-side air flow blocking plate and the right-side air flow blocking plate are blown by an air flow flowing from outside environment into a case through the fan unit that is in a malfunction state, thereby rotating by respectively taking the left-side support pole and the left-side support pole as a rotary center thereof. Consequently, the left-side air flow blocking plate and the right-side air flow blocking plate are stopped rotating by the stop member, such that the air flow is blocked, by the two air flow blocking plates, from being entering the case.
