Abstract: Provided is a driver assembly for driving a moving component. The driver assembly includes: a motor; a transmission portion; and an execution portion; and a shape memory alloy wire connecting the moving component with the execution portion. The moving component is slidably connected to the transmission portion and spaced apart from the execution portion. The motor can drive the transmission portion to lead the execution portion to move along a first direction, in such a manner that the moving component is driven by the shape memory alloy wire to move along the first direction. The shape memory alloy wire is configured to drive the moving component to move along the first direction relative to the execution portion under an external electrical signal. When being applied in the camera module, the driver assembly can drive the movable lens assembly to move along an optical axis, facilitating the zooming and autofocus.

Abstract: Provided is an imaging assembly and a camera. The imaging assembly includes an infrared sensor, a visible light sensor, and a wavelength-selective reflector. The wavelength-selective reflector is configured to reflect the infrared light of the incoming light to the infrared sensor, and transmit the visible light of the incoming light to the visible light sensor. With such a design, the infrared sensor and the visible light sensor can share a part of the optical path to reduce an occurrence possibility of errors between the two, thereby reducing the parallax difference, and optical openings of the imaging assembly can also be reduced. Moreover, since the infrared light and the visible light are from the same incoming light, thereby facilitating matching of a detection result of the infrared sensor and a detection result of the visible light sensor.

Abstract: The present invention provides a zoom lens, at least including a first camera lens, a second camera lens, a first motor assembly, and a housing. The first camera lens and the second camera lens are installed in the housing. The first motor assembly is installed to the housing and connected to the first camera lens, so as to drive the first camera lens to move relative to the second camera lens to change a focal length. For the zoom lens provided by the present invention, the first camera lens is driven by the first motor assembly, which requires a lower cost, a simpler structure, and is easier to process, thereby better meeting the actual use requirements.

The cover includes an installation cavity, and the first magnetic device is connected to the cover. Each of the at least two lenses is movably arranged in the installation cavity and provided with a second magnetic device. The first magnetic device is configured to attract the second magnetic device to calibrate each of the at least two lenses, in such a manner that axes of the at least two lenses coincide with each other. The zoom lens group can calibrate the camera lenses, thereby increasing precision of the zoom lens group and improving the imaging effect.

Abstract: Provided is a camera module, including: a lens group including a lens barrel and a camera lens; and a driver assembly configured to drive the camera lens to move and including a magnetic portion. The camera lens includes a magnetic matching portion. The magnetic portion and the magnetic matching portion are respectively located at two ends of a side wall of the lens barrel in a thickness direction, and are connectable to each other through magnetic attraction, in such a manner that the camera lens is driven by the driver assembly to move along the optical axis of the camera lens. In this way, the side wall of the lens barrel is free of a through hole, so that light is prevented from entering the lens barrel via the through hole, thereby prolonging the lifetime of the camera module and improving the image-capturing effect.

Abstract: The present disclosure provides a lens module. The lens module includes: a base; a lens carrier movably installed to the base; a driver configured to connect the base with the lens carrier in a transmission way and to drive the lens carrier to partially expand out of or retract into the base; and a magnet assembly provided correspondingly at the base and the lens carrier. The lens carrier can be in press fit with an inner wall of the base under a magnetic force of the magnet assembly, so that the lens carrier can maintain relatively fixed with the base in a direction perpendicular to a telescoping direction during expansion and retraction of the lens carrier. Therefore, the lens carrier and the base can always maintain precise coaxiality in the telescoping direction.

The illumination window has an annular shape and surrounds the lens assembly. The present disclosure can solve a problem in the related art that the camera and the illumination assembly are separate components, which would otherwise occupy a space.

Abstract: The present disclosure provides a lens assembly, including a housing having a receiving space and including a base and a shell that is assembled with the base to form the receiving space, an optical lens received in the receiving space, an anti-jitter mechanism including a driving member, and an anti-jitter bracket; an imaging sensor; and an infrared filter. The anti-jitter bracket includes a support member arranged opposite to and spaced apart from the base. The support member is provided with a light-transmitting window corresponding to the optical lens. The infrared filter covers the light-transmitting window. The infrared filter and the support member are formed into one piece. Compared with the lens in the related art, the present lens assembly can directly arrange the infrared filter on the anti-jitter bracket without additionally providing a mounting member especially for mounting the infrared filter, thereby simplifying the overall structure of the lens assembly.

Abstract: The present invention relates to a filter assembly includes a substrate including a surrounding wall forming an inner cavity and an extension wall extending from the surrounding wall into the inner cavity of the substrate, a filter mounted on the substrate, and a spacer fixed to a bottom surface of the extension wall. The extension wall forms a receiving cavity for receiving the filter, the filter is received in the receiving cavity, and a bottom portion of the filter is fixed to the spacer. A glue-receiving groove is formed between a side surface of the filter and a side surface of the extension wall. Glue is provided in the glue-receiving groove to bond the filter with the extension wall. The requirement on a height of the substrate when encapsulating the filter is reduced, thereby solving the problem that the encapsulation height of the existing filter assembly is over large.
