Abstract: A lens protection structure includes a base, a polyester film, a first silica gel, a second silica gel, and a protective cover. Each of the base, the polyester film, the first silica gel, and the second silica gel defines a through hole for cooperatively receiving a lens. The polyester film is coupled to a surface of the base, and the first silica gel is coupled to a surface of the base opposite the polyester film. The second silica gel is coupled to the polyester film. The protective cover is coupled to the second silica gel and seals a receiving cavity within the base. At least one air escape channel is defined in the base. The at least one air escape channel communicates the receiving cavity of the base to an exterior of the lens protection structure.

Abstract: A lens module includes a lens assembly, a voice coil motor, a bracket, a circuit board, and a solder block. The voice coil motor includes a pin. The lens assembly is received in the voice coil motor. The bracket is disposed on the voice coil motor. The pin is extending into the recessed area. The bracket is sandwiched between the voice coil motor and the circuit board. The circuit board includes conductive supporting blocks facing the voice coil motor. The conductive supporting blocks are disposed in the recessed area. And one pin and one conductive supporting block are electrically connected by the solder block. The present disclosure also provides an electronic device including the lens module.

Abstract: A lens module includes a lens holder and a lens. The lens holder comprises a through-hole. The lens holder comprises an inner wall surrounding to define the through-hole. A first thread is formed on the inner wall. A second thread is formed on an outer sidewall of the lens. The first thread cooperates with the second thread to fix the lens on the lens holder. At least one first slot is defined on the outer sidewall of the lens and around a periphery of the lens, and a seal ring is received in each first slot. At least one second slot is defined on the outer sidewall of the lens along a direction of an optic axis of the lens. Each second slot passes through each first slot to form a receiving space. The disclosure also provides an electronic device having the lens module.

Abstract: A lens module includes a lens assembly and a lens barrel assembly receiving the lens assembly. The lens barrel assembly includes a lens holder and a lens barrel provided on the lens holder. A light transmission hole is defined passing through the lens holder and the lens barrel. The lens assembly is received in the light transmission hole. A center of the lens barrel is offset from a center of the lens holder.

Abstract: A bracket includes a first surface and a second surface opposite to the first surface. A first receiving groove is defined from the second surface to the first surface. At least one air escape hole defined from the first surface to the second surface. The air escape hole is connected to the first receiving groove. At least one sealing compound is filled in the air escape hole. An air escape passage is formed between the sealing compound and an inner wall of the air escape hole. The disclosure also relates to a camera module and an electronic device. The bracket can dissipate heat or moisture absorbed into the bracket and prevents dust and debris from entering into the interior of the camera module.

Abstract: A method for fabricating a composite lens holder with low-mass conductive metal and high-precision placement thereof to enable smaller-scale fabrication includes the steps of forming a plastic lens holder as a matrix, laser etching an outer surface of the plastic lens holder to form surface patterns, and electroless plating of metal on the surface patterns to form an effective coil, thereby producing the composite lens holder. A voice coil motor and an electronic device which use such a composite lens holder are also disclosed.

Abstract: A camera module reinforced against excessive torque forces when being installed includes a lens bracket and a lens barrel. The lens bracket includes an internally-threaded receiving barrel, the lens bracket having external threads around its circumference. The external threads match the internal threads, and lower end of the lens bracket includes an annular groove, a resilient ring being received in the annular groove.
