【Detailed ways】

Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

As shown in the figure, the mechanism device of the optical lens includes a fixed group and a power drive group and a transmission group arranged on the fixed group. The fixing group includes a fixing frame 21 and a substrate frame 22 . The power drive group includes a drive motor 11 and a transmission gear set 12 .

The transmission group includes a first CAM cylinder 31, a second guide cylinder 32, a third guide cylinder 33, a fourth CAM cylinder 34, a fifth CAM cylinder 35, a second group of brackets 36, two Group 37, the sixth guide cylinder 38.

Specifically, the fixed frame 21 is provided with a CAM groove 211 and a straight groove 212, and a ring gear 314, a first guide post 311, a first CAM groove 312 and a first small straight groove are respectively arranged on the first CAM cylinder 31. Groove 313. The ring gear 314 of the first CAM cylinder 31 meshes with the transmission gear set 12 , and the first guide post 311 is mounted on the CAM groove 211 of the fixed frame. When the driving motor 11 receives the electronic signal and performs high-speed rotational movement, the transmission gear set 12 coincides with the ring gear 314 on the first CAM cylinder 31, and the first CAM cylinder 31 is driven by the gear to rotate, and the first guide post 311 is installed On the CAM slot 211 of the fixed frame, the first CAM barrel 31 moves axially and rotationally along the track of the CAM slot 211 at the same time.

A drive rod 221 is provided on the substrate frame 22 . The driving rod 221 includes a straight side 2211 and a beveled side 2212 .

A second large guide post 321, a second small guide post 322, a second CAM groove 323, a second deep straight groove 324 and a second shallow straight groove 325 are respectively provided on the outer circle of the second guide cylinder 32. Two large guide pillars 321 are disposed in the straight groove 212 .

The fourth CAM barrel 34 is provided with a fourth guide post 341 and a fourth CAM slot 343 , and the fourth guide post 341 passes through the second CAM slot 323 and is arranged on the first small straight slot 313 . The fourth guide post 341 of the fourth CAM cylinder 34 is installed on the small straight groove 313 on the second CAM cylinder. As the first CAM cylinder 31 rotates, the fourth CAM cylinder 34 is also driven to rotate. In addition to being installed in the first small straight groove 313 of the first CAM cylinder 31, the fourth guide post 341 on the CAM cylinder 34 is also installed in the second CAM groove 323 on the second guide cylinder 32. The second guide The cylinder 32 is fixed on the straight groove 212 of the fixed frame and cannot be rotated. Therefore, when the first CAM cylinder 31 rotates, the fourth CAM cylinder 34 is driven along the second CAM groove on the second guide cylinder 32. 323 makes axial and rotational movement simultaneously.

A guide column 361 , a limiting column 362 , a fixing hole 363 , a notch 364 and a viewing window 365 are respectively provided on the two groups of brackets 36 . The guide post 361 is disposed on the fourth CAM groove 343 on the fourth CAM barrel. Because the second guide cylinder 32 can not do rotational movement, but because the guide post 361 on the second group support 36 is installed in the fourth CAM slot on the fourth CAM cylinder 34, so the second group support can do axial ascending and descending movement.

The second group 37 is respectively provided with a rotating shaft 182 and a swing rod 372, the rotating shaft 182 is installed in the fixing hole 363 of the second group bracket, and the driving rod 221 can drive the swing rod 372 to rotate and realize the swing of the second group 37.

A sixth guide post 381, a large guide piece 382 and a small guide piece 383 are respectively arranged on the sixth guide cylinder 38. The slot 324 and the second shallow straight slot 325 ; the sixth guide post 381 is inserted into the notch 364 on the second group bracket 36 .

A bracket 371 and a torsion spring 41 are also provided on the second group 37, and an optical lens 42 is arranged at the circular hole in the center of the second group. The fifth CAM cylinder 35 has a fifth CAM groove 351 and a fifth guide groove 352 on its outer circle, and a fifth straight groove 353 on its inner circle.

After the fixed group, the power driving group and the transmission group are installed together, the driving rod 221 provided on the substrate frame 22 acts on the swing rod 372 on the second group 37, when the swing rod 372 of the second group touches the straight edge 2211 of the driving rod At the same time, the second group 37 swings to the window 365 of the second group support 36 under the effect of the drive rod 221 . When the whole mechanism moves upwards, after the swing rod 372 of the second group 37 acts on the hypotenuse 2212 of the driving rod, the second group 37 gradually resets under the torsion force of the torsion spring 41 until the bracket 371 provided on the second group 37 reaches the limit The edge of column 362, at this moment the optical center of the second group just coincides with the optical center of the whole lens. When the lens realizes high-magnification imaging, that is, when the lens rises, the second group 37 gradually moves away from the substrate frame 22 and returns to the center; Inside.
