Abstract: An unmanned aerial vehicle includes a body, a shaft base, an arm, and a clamping assembly. The shaft base is disposed outside the body. The arm is pivotally disposed on the shaft base and is movably close to the body or unfolded from the body. The clamping assembly is movably and pivotally disposed on the shaft base and surrounds a periphery of the shaft base. When the arm is close to the body, the arm is limited between the body and the clamping assembly. During an unfolding process of the arm, the clamping assembly is pushed by the arm to be pivotally rotated on the shaft base. When the arm is unfolded from the body, the clamping assembly clamps the arm along a radial direction of the arm by an elastic force.

Abstract: A projector includes a color wheel module and an optical engine. The color wheel module includes a rotation device, a mount, a color wheel, and an optical sensor. The color wheel is fixed on a rotary part of the rotation device. The rotation device and the optical sensor are fixed on the mount. The mount has an anti-dust structure includes a curved surface that is opposite to a rotary surface of the rotary part and extends in a rotation direction of the rotary part. The curved surface and the optical sensor are arranged sequentially in the rotation direction. Either by shortening a distance between the curved surface and the rotary surface or by a guiding slot that is disposed beside or lower than the curved surface, dust deposited on the optical sensor can be reduced effectively.

Abstract: An optical engine module includes a casing, a bracket, a light pipe, a cover and a resilient member. The casing has an accommodating space and a baffle, wherein the baffle is located in the accommodating space. A first end of the bracket has at least one first block portion, the bracket is disposed in the accommodating space, and a second end of the bracket is oriented towards the baffle, wherein the first end is opposite to the second end. The light pipe is disposed in the bracket and abuts against the at least one first block portion. The cover is disposed on the second end of the bracket and abuts against the baffle. The resilient member is configured to generate an elastic force to push the bracket towards the baffle.

Abstract: A projector includes a holding casing having a hole structure, a projection lens movably disposed through the hole structure, a containing casing detachably fixed to the holding casing for forming a containing space, an image projection module disposed in the containing space, and a flexible washer. A first engaging structure is formed on an external surface of the projection lens. The flexible washer jackets the projection lens and has first and second ring structures and a connection ring structure formed therebetween. The first engaging structure is engaged with the second engaging structure of the first ring structure for positioning the first ring structure on the projection lens. The second ring structure is clamped between the holding casing and the containing casing for sealing the containing space cooperatively with the connection ring structure and the first ring structure when the containing casing is fixed to the holding casing.
