The coils are respectively fixed on two opposite sides of the base, the magnets are fixed on two opposite sides of the lens assembly respectively, and the magnets are located by inner sides of the coils respectively, the lens assembly is clamped by the leaf springs and supported on the base, the coils drive the magnets and the lens assembly to move after being energized. The camera module is simply structured, easy to assembly, less bulky and fit for the demand of thin products.

Camera module

A camera module includes a lens assembly, a voice coil motor assembly, an image sensor assembly and a flash assembly. The lens assembly is installed in the voice coil motor assembly along an optical axis direction, the image sensor assembly is located below the lens assembly, the flash assembly is mounted above the voice coil motor assembly and includes at least one light source located around a lens of the lens assembly, and the light source adapted for providing a flash for the lens. The flash assembly can provide uniform and even flashing light for the lens to improve imaging quality, and provide compact structure to meet the development of the electronic products miniaturization.

A camera module includes a lens assembly, a voice coil motor assembly for receiving and driving the lens assembly, and an image sensor assembly located below the voice coil motor assembly. The voice coil motor assembly comprises a bottom unit that is hollow and a color filter supported by the bottom unit, the color filter, the lens assembly and the image sensor assembly are coaxial, the bottom unit has an upper portion and a lower portion that are integrated together, the upper portion is configured around the lens assembly, and the bottom unit is configured below the lens assembly and supports the color filter. The camera module has simple structure and convenient assembly, can reduce total assembly tolerances of the camera module, achieve an accurate optical axis alignment between the lens and the image sensor, and reduce manufacturing cost to benefit the popularization in industries.

A voice coil motor includes a housing having a cavity; a movable assembly received in the cavity; a fixing assembly configured outside of the movable assembly; and a first spring plate and a second spring plate configured at an upper surface and a lower surface of the movable assembly respectively. The fixing assembly comprises at least two magnetic elements connected with the first spring plate and a spacer member configured on the second spring plate to connect the second spring plate to the magnetic elements or the housing. The voice coil motor is served as an actuator of electronic products such as digital cameras, mobile phones, and digital cameras, which has thin thickness, good performance and strong applicability.

Voice coil motor

A camera lens module includes a case and a bottom coupled with the case to form an accommodating space, having an upper spring, a lens assembly and a lower spring accommodated in the accommodating space. The lens assembly includes a lens barrel main body and a group of lenses provided in the lens barrel main body. An upper end of the lens barrel main body is suspended on the upper spring, and a lower end of the lens barrel main body is suspended on the lower spring. The upper spring is connected with the case, and the lower spring is connected with the bottom. In the camera lens module, the lens assembly is directly suspended on upper and lower springs. This eliminates the camera lens mount of existing camera lens module as well as the connecting screw structure between the camera lens mount and the lens barrel.

Camera lens module
