Description
The utility model relates to a kind of camera lens focus adjusting mechanism.
Existing camera lens focus adjusting mechanism especially uses the lens focussing adjustment machine structure on digital still camera, is mostly to utilize the cooperation displacement principle of cam curved surface to come moving lens to focus.Existing lens focussing adjustment machine structure for example shown in Figure 1 (FUJI DS-7 type digital still camera internal lens mechanism), mainly be that camera lens 1 is sleeved in the sleeve 2, and utilize spring with both combinations, the slip that cooperates by the cam curved surface 3 on the projection on the camera lens 14 and the sleeve 2, when turnbarrel 2, cam curved surface 3 will promote (or retracting) projection 4, the motion of (or retreating) thereby drive camera lens 1 work advances.Yet because this cam curved surface has structural defective, the degree of tilt of its cam curved surface can not be too oblique, otherwise will cause the instability (easily cause camera lens to rock or locate inaccurate) of camera motion.Therefore, generally in manually operated design, all can only do the switching focusing action of two-part, and the distance of camera lens displacement is also unsuitable oversize.In fact, because two corresponding the structure that is arranged in pairs in sleeve is all adopted in the design of this cam curved surface, the stability during with the increase camera motion.If the camera lens switched design surpasses more than two sections, the un-reasonable phenomenon of the length long (it is over half to surpass the sleeve circumference) of cam curved surface then will take place.When if desire changes over automatic switchover with this existing lens focussing adjustment machine structure, then will be difficult for, and cause relevant camera lens detent mechanism amount of parts to increase, the difficulty that assembling is difficult for because of the location of cam curved surface structure.
The purpose of this utility model is: a kind of camera lens focus adjusting mechanism is provided, makes it simple in structure, be easy to assembling, and can reach automatically, manually all can the focusing of multisection type camera lens switch and accurate location.
The purpose of the utility model manual focusing mechanism is achieved in that in the camera lens focus adjusting mechanism of a kind of removable camera lens with the adjustment focal length, includes a guiding mechanism, a screw rod and a gear train.Guiding mechanism is arranged on the camera lens, and bootable camera lens only can focus on the direction motion of optical axis towards it.Screw rod extends along the focused light direction of principal axis of camera lens and is provided with, and at an end of screw rod the adjustment button is housed, and can drive the screw rod rotation by rotating this adjustments button.Gear train is fixedly installed on the camera lens, and this gear train is engaged on the screw rod, rotatablely moving of screw rod can be transferred to camera lens, and camera lens is moved along the direction of guiding mechanism.
The purpose of the utility model automatic focusing mechanism is achieved in that in the camera lens focus adjusting mechanism of a kind of removable camera lens with the adjustment focal length, includes a guiding mechanism, a screw rod, a motor and a gear train.Guiding mechanism is arranged on the camera lens, and bootable camera lens only can be towards its focused light direction of principal axis motion.Screw rod extends along the focused light direction of principal axis of camera lens and is provided with, and at an end of screw rod one gear is housed, but the rotation of screw rod mate gear and rotating synchronously, but the rotation of motor driven gear.Gear train is fixedly installed on the camera lens, and this gear train is engaged on the screw rod, rotatablely moving of screw rod can be transferred to camera lens, and camera lens is moved along the direction of guiding mechanism.
No matter the utility model camera lens focus adjusting mechanism is automatically or manual, its gear train all can be one be arranged on the camera lens and with the tooth bar of screw engages transmission; Also can be a swivel nut that is arranged on the camera lens, in swivel nut, be provided with the screw thread of corresponding engagement with screw rod.Its guiding mechanism all can be one and is fixedly mounted on the sliding sleeve that also can be enclosed within on the camera outside the camera lens; Or be fixedly mounted on the camera, and can place the chute of camera lens thereon.
Owing to adopt above-mentioned two kinds of technical schemes, adjust button by manual rotation and drive screw rod and rotate, again by with the gear train of screw engages, the camera lens that is fixed on the gear train is moved along the guiding mechanism direction, realize manual focusing.Perhaps, drive screw rod again and rotate synchronously,, rotatablely moving of screw rod is transferred to camera lens, camera lens is moved along guiding mechanism, realize automatic focusing by being engaged on the gear train on the screw rod by the motor driving gear rotation.The utility model is by screw drive mechanism simple in structure and that be easy to assemble, reach automatically, manually all can the focusing of multisection type camera lens switch and accurate location.
