Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Refer to Fig. 1-4, a kind of camera actuator casing 100, it comprises: shell 10, loading plate 20, camera lens module fitted tube 30, metal lining 35 and guide posts 40.
This loading plate 20 has first surface 21, and this first surface 21 offers through hole 22 and is provided with multiple protruding 210.The plurality of protruding 210 arrange around this through hole 22.One end of this guide posts 40 is inserted this through hole 22 and is fixed in this through hole 22, in present embodiment, can this end of this guide posts 40 is fixed in this through hole 22 by glue.This loading plate 20 is used for installing image sensor (not shown).
This camera lens module fitted tube 30 is plastics.This camera lens module fitted tube 30 be positioned on this loading plate 20 and comprise second surface 31 and with opposing the 3rd surface 32 of second surface 31.This camera lens module fitted tube 30 offers the bearing holes 33 that runs through this second surface 31 and the 3rd surface 32.This second surface 31 contacts with this first surface 21.The inside surface of this bearing holes 33 is provided with screw thread.This bearing holes 33 is for carrying camera lens module (not shown).
This camera lens module fitted tube 30 also comprises through hole 34.This through hole 34 runs through this second surface 31 and the 3rd surface 32, and this through hole 34 arranges separately with this bearing holes 33.In present embodiment, this through hole 34 is the edges that are opened in second surface 31 and the 3rd surface 32, the second hole 342 that this through hole 34 comprises the first hole 341 and separates with the first hole 341, and this first hole 341 equates with the coaxial setting in this second hole 342 and internal diameter.This camera lens module fitted tube 30 also comprises depressed part 343, and this depressed part 343 is between this first hole 341 and this second hole 342.This metal lining 35 is fixed on this through hole 34, particularly, the two ends of this metal lining 35 are separately fixed in this first hole 341 and this second hole 342, for example, by this depressed part 343 to the gap point glue between gap and this metal lining 35 and this second hole 342 between this metal lining 25 and this first hole 341, and solidified glue, the two ends of this metal lining 35 can be fixed on this first hole 341, this second hole 342 in.
The length of this metal lining 35 is consistent with the height of this camera lens module fitted tube 30.
The material of this guide posts 40 is metal.This metal lining 35 comprises center pit 350.Thereby this guide posts 40 can be housed in this center pit 350 actively by this camera actuator casing 100 during for the focusing of camera lens module, and this camera lens module fitted tube 30 can move along this guide posts 40.Dynamic inclination between this guide posts 40 and this camera lens module fitted tube 30 is determined by the gap between this guide posts 40 and this center pit 350.In the present embodiment, gap between this center pit 350 of this guide posts 40 and this metal lining 35 is between 3um ~ 5um, with this understanding, between this metal lining 35 and this center pit 350, can reach optimized effect, be exactly under this state, can not produce excessive dynamic inclination, and the friction energy of this guide posts 40 and this center pit 350 drops to minimum.
This shell 10 is arranged on this loading plate 20 and is positioned at the outside of this camera lens module fitted tube 30.This shell 10 comprises on 101, the four surfaces 101, the 4th surface and is provided with multiple grooves 102, thus the plurality of protruding 210 and the plurality of groove 102 match this shell 10 is fixing with this loading plate 20.
In sum, the camera actuator casing that embodiment of the present invention provides, by metal lining being set in through hole the inside, when metal lining and camera lens module fitted tube move with respect to guide posts, metal is fewer than the friction force of metal and plastics with the friction force of metal on the one hand, has reduced frictional dissipation, improves the dynamic inclination of guide posts and camera lens module, on the other hand, the plastic particles that can avoid damaging falls into image sensor and affects the normal work of image sensor.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to the claims in the present invention with distortion.
