Abstract: An angle detecting device for detecting a bending angle of an element. The element comprises a first connecting portion and a second connecting portion bent relative to the second connecting portion. The angle detecting device comprises a fixing member, a non-contact range finder and a base. The fixing member comprises a first fixing portion and a second fixing portion. The fixing member and the non-contact range finder is mounted on the base. The first fixing portion cooperates with the second fixing portion to fix the first connecting portion. The non-contact range finder faces the second connecting portion to detect a distance between the second connecting portion and the non-contact range finder, and determine whether the distance is within a preset range. An angle detecting method using the above angle detecting device is also provided.

Abstract: Camera module with switchable light filters includes a lens, a body, a movable tray, a first filter, a second filter, a gear and a protective cover. The lens is disposed in the body. The body defines a first through hole corresponding to the lens and includes a first surface. The movable tray is positioned on the first surface and is used for receiving the first filter and the second filter. The gear is arranged on the first surface by a rotating shaft, the gear is configured to engage with the movable tray to switch the first filter and the second filter. The protective cover is disposed on the body and partially covers the gear.

Abstract: A camera module includes a voice coil motor, a lens module, a substrate, an imagine sensor, a circuit board and a conductive adhesive tape. The voice coil motor includes a conductive housing defining a first hole. The lens module is received in the first hole. The substrate supports the voice coil motor and defines a second hole. The circuit board includes a grounding area. The image sensor is supported by the circuit board, and is received in the second hole, and aligned with the lens module. The conductive adhesive tape covers the substrate and electrically connects the conductive housing to the grounding area.

Abstract: A camera module includes a circuit board, an image sensor, a bracket, a VCM, and a lens module. The image sensor is positioned on the circuit board. The bracket is mounted on the circuit board and receives the image sensor. The VCM is mounted on the bracket and includes a conductive housing and pins extending from the housing. The pins are electrically connected to the circuit board. The lens module is received in the VCM. The VCM with the lens module is supported on the bracket. The optical axis of the lens module is coinciding with a center of the image sensor. The bracket includes a plating layer and solder bumps. The plating layer is formed at least one of side surfaces of the bracket. The solder bumps electrically connect the plating layer to the circuit board and electrically connect the plating layer to the housing.

Abstract: Camera module with switchable light filters includes a lens module, a bearing rotating device, a visible light filter, and an infrared light filter. The bearing rotating device includes a rotating shaft, at least one guiding stick, and a bearing plate. The rotating bearing plate holds the two filters and defines an arcuated guiding slot. The circle center of the arcuated guiding slot is the rotating shaft. A visible light filter and an infrared light filter are switchable, their movement being governed by the guiding stick and the guiding slot, to respective alignment with an optical axis of the lens module. The camera module can rotate the bearing plate to switch the infrared filter for the visible filter where the acquisition of infrared light is required.
