Description

Camera lens shockproof platform set

The invention relates to a lens, in particular to a camera lens shockproof platform set.

In order to overcome the problem of camera shake during photographing or photography, the most common solution at present is to install a movable optical sensor inside the camera lens, so that the sensor remains stable even in a slightly vibrating environment. A blurred image is produced due to shaking.

The anti-shake mechanism in the camera, as shown in the seventh figure, is usually provided with a driving member 82 and an optical sensor 84 directly on a moving platform 80. When the sensor inside the camera detects the camera shake, the sensor can generate a signal to enable the driving member 82 to drive the moving platform 80 to adjust the position of the optical sensor 84 to offset the amplitude of the camera and capture the image. It will be more clear.

However, in the components of the anti-shake mechanism described above, the optical sensor 84 and the driving member 82 are both disposed on the same moving platform 80, and the driving member 82 is located at the side of the platform 80 at a position offset from the center of the platform 80. When the driving member 82 drives the platform 80 to be offset, the platform 80 is slightly moved closer to a portion of the driving member 82, and then the entire moving platform 80 is driven, so that the moving platform 80 cannot be smoothly shifted, and the resistance is easily generated. The movement is slow, and the optical sensor 84 cannot stably capture images, thereby reducing the anti-shake effect.

Therefore, the main object of the present invention is to provide a camera lens anti-vibration platform group, which can relatively stably and accurately adjust the position of the optical sensor and improve the anti-shock effect.

In order to achieve the above objective, the camera lens anti-vibration platform group provided by the present invention comprises a first platform and a second platform, the first platform has a driving component; the second platform has an optical sensor, The second platform is movably coupled to the first platform, so that the first platform can drive the second platform to be displaced; and by using the component member, the invention can move the second platform in a relatively stable and accurate state. Make the image more clear and achieve the purpose of improving the anti-shake effect.

The detailed construction of the present invention and its features are set forth in the following description of the embodiments of the invention.

BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be described in detail with reference to the preferred embodiments of the preferred embodiments in which: FIG. 1 is a schematic view of the first preferred embodiment of the present invention; The partial front view of the first preferred embodiment mainly shows the state of the first platform; the third figure is an exploded perspective view of the second preferred embodiment of the present invention; and the fourth figure is the second preferred embodiment of the present invention. 5 is an exploded perspective view of a third preferred embodiment of the present invention; and a sixth view is a rear view of a third preferred embodiment of the present invention.

Please refer to the first and second figures, which are the camera lens anti-vibration platform group 10 provided by the first preferred embodiment of the present invention, including a first platform 20 and a second platform 30. The first platform 20 has a frame 22, and one of the sides of the frame 22 is provided with an extension arm 24. The extension arm 24 is located near the center of the frame 22 and extends outward. The outer end of the extension arm 24 has two jaws 26 and a guide groove 27 formed between the jaws 26, and the guide groove 27 extends in the vertical direction. Each of the clamping jaws 26 has a positioning portion 28 opposite to the side wall of the guiding groove 27, and a driving member 16 is further disposed under the extending arm 24 of the first platform 20.

An optical sensor 18 for capturing images is disposed in the center of the second platform 30. One side of the second platform 30 is provided with a guiding rod 32 extending in a vertical direction, and the second platform 30 is disposed outside the guiding rod 32. There is a sensor 14, and the inductor 14 in this embodiment is a Hall sensor.

The first platform 20 is embedded in the guide bar 32 of the second platform 30 by the two jaws 26 of the extension arm 24, so that the guide bar 32 is fixed to the extension arm 24 by the positioning portion 28 of each jaw 26. When the second platform 30 and the optical sensor 18 generate a vibration phenomenon, the sensor 14 detects the amplitude of the vibration and sends a signal for controlling the driving member 16, so that the driving member 16 drives the first platform 20 to move up and down linearly. The extension arm 24 of the first platform 20 can synchronously push the micro-displacement of the second platform 30 as an effect of adjusting the compensation vibration displacement.

Since the extension arm 24 of the first platform 20 is positioned on the guide bar 32 of the second platform 30, and then the second platform 30 is pushed, the thrust of the driving member 16 can directly and vertically move the second platform 30 up and down. The second platform 30 does not cause relative rotation or tilting, and the optical sensor 18 can move in a relatively stable and accurate state, and the image is more clearly obtained, thereby achieving the purpose of improving the anti-shake effect.

As shown in the third and fourth figures, the camera lens anti-vibration platform group 40 of the second preferred embodiment of the present invention further includes a first platform 41 and a second platform 42 and is characterized by an extension of the first platform 41. The arm 43 has a pivot 44 that is a predetermined distance from the guide groove 45 at the outer end of the extension arm 43. The second platform 42 is provided with a fixing portion 46 formed at a side center line position of the second platform 42. The fixing portion 46 of the second platform 42 is located in the guiding groove 45 of the extending arm 43, and the pivot 44 of the first platform 41 is pivotally disposed on the positioning hole 48 of the platform 47 outside the first and second platforms 42. With the above-mentioned constituent members, when the first stage 41 is driven by the driving member 49, the first stage 41 rotates in the center of the pivot 44, and the extending arm 43 drives the second stage 42 up and down by the guiding groove 45. Since the fixing portion 46 is located at the near-mass center position of the second platform 42, the extension arm 43 can push the second platform 42 with a relatively even and stable distribution force, so that the second platform 42 and the optical sensor 50 move relatively smoothly.

Further, in the fifth and sixth figures, the camera lens anti-vibration platform group 60 provided by the third preferred embodiment of the present invention is substantially the same as the second preferred embodiment, and is characterized by the extension of the first platform 61. A pivot 62 is disposed on the outer end of the arm 65, and the pivot 62 is pivotally disposed on the positioning hole 64 of the outer platform 63. The guiding groove 66 of the extending arm 65 is disposed at a predetermined distance from the pivot 62. The fixing portion 68 of the second platform 67 is formed at a position near the center of the back mass and is located in the guiding groove 66 of the extending arm 65. Therefore, when the first platform 61 moves, the first platform 61 is also deflected by the pivot 62, and then the fixing portion 68 is driven by the extending arm 65, thereby stably moving the second platform 67, which can also achieve the purpose of the invention. .
