Abstract: The disclosure discloses a reflow-solderable vehicle-mounted lens module configured to be capable of performing imaging for near-infrared light, the vehicle-mounted lens module including: a lens barrel and a lens group disposed within the lens barrel, the lens group including a plurality of lenses, wherein at least one of the lenses is made of polyetherimide by means of injection molding, the lens made of polyetherimide being injection molded by setting a mold temperature controller at a temperature higher than 265° C.; wherein the near-infrared light has a wavelength ranging from 800 to 1,100 nm, and the highest ambient temperature for the reflow soldering is set at 230 to 260° C.; the vehicle-mounted lens module can ensure stable and consistent performance of a module system before and after undergoing a reflow soldering process.

Abstract: The disclosure provides a double barrels lens, a lens module, and an assembling method therefor. The double barrels lens includes a first barrel and a second barrel. The first barrel comprises a first end, a second end and a lens group. External screw threads are provided on an outer surface of the second end. The second barrel includes a first end surface, a second end surface and an inner surface with internal screw threads. The internal screw threads of the second barrel are engaged with the external screw threads of the first barrel. A distance H between an optical center of the lens group and the second end surface of the second barrel, a focal length f of the lens group, and a correction coefficient ? meet the expression: H=f+?.

Abstract: The disclosure provides a camera module and an assembling method therefor. The camera module includes a lens, a holder, an image sensor assembly, and one or more self-locking screws for fixing the lens, the holder and the image sensor assembly. The holder is provided with a lens mounting hole for assembling the lens and one or more screw holes for assembling the one or more self-locking screws. The holder includes a supporting platform, a location guiding sleeve and internal threads. The lens (100) includes external threads engaged with the internal threads, a location guiding step cooperated with the location guiding sleeve, and a limiting ring cooperated with the supporting platform.
