This utility model is by the following technical solutions.
A kind of general economical M12 lens base, described lens base is through injection moulding integrated molding, it includes lens interface and base, lens interface adopts the barrel with M12 × 0.5 specification screw thread to coordinate with all M12 specification camera lenses, and the upper and lower lateral symmetry of barrel sidewall offers two locking through holes for fixed lens position; Barrel is positioned at base upper surface central authorities and one-body molded with base, base central authorities offer the light hole passed through for camera light, described light hole connects with barrel, the base left and right sides is arranged with base fixed via, the base lower surface place of base fixed via side is provided with and subtracts glue blind hole, the corner place of base lower surface be provided with connect with external optical drive mechanism by face recess.
Described lens base enters order on light direction at lens interface and is divided into main body withdrawing pattern section and by face recess molding section two parts, described it is positioned against face recess withdrawing pattern section by face recess, when lens base is with Shooting Technique molding, described main body withdrawing pattern section through main body withdrawing pattern stripping forming, described by face recess withdrawing pattern Duan Jing by face recess withdrawing pattern stripping forming.
Described lens base is with plastic rubber shaping.
In this utility model, lens base is through injection moulding integrated molding, it includes lens interface and base, and lens interface adopts the barrel with M12 × 0.5 specification screw thread to coordinate with all M12 specification camera lenses, and the upper and lower lateral symmetry of barrel sidewall offers two locking through holes for fixed lens position; Barrel is positioned at base upper surface central authorities and one-body molded with base, base central authorities offer the light hole passed through for camera light, described light hole connects with barrel, the base left and right sides is arranged with base fixed via, the corner place of base lower surface be provided with connect with external optical drive mechanism by face recess; Owing to adopting Shooting Technique to produce, therefore it is less costly, and this structure has good versatility, is provided with the good compatible M12 camera lens of barrel energy, and base position is additionally provided with and can dock with main flow optical lens driving mechanism by face recess.
In this utility model, the base lower surface place of base fixed via side is provided with and subtracts glue blind hole, and this design can effectively eliminate the shrinking deformation phenomenon produced in Shooting Technique so that the size of finished product base can be consistent with original design, it is ensured that the focusing ability of finished product.
In this utility model, lens base enters order on light direction at lens interface and is divided into main body withdrawing pattern section and by face recess molding section two parts, described it is positioned against face recess withdrawing pattern section by face recess, when lens base is with Shooting Technique molding, described main body withdrawing pattern section is through main body withdrawing pattern stripping forming, described by face recess withdrawing pattern Duan Jing by face recess withdrawing pattern stripping forming, this design makes product can control to lean on the draft depths of face recess withdrawing pattern section when batch production, due to when draft depths is sufficiently small, by face recess namely without designing draw taper, and the driving without gradient is conducive to the improving product driving stability when docking with optical lens driving mechanism by face, therefore this design of this product improves the product compatibility to optical lens driving mechanism further.
