Stabilization method for optical device and components thereof

Abstract

The invention provides an optical device, which includes: a base, an image sensing unit, an outer frame, an inner frame, and a lens group. The image sensing unit is arranged on the base, the outer frame is connected to the base and has a plane, the inner frame has a protrusion, and can move between a first position and a second position relative to the base, and the lens group It is arranged on the inner frame body and has an optical axis. When the inner frame moves to the first position, the protrusion abuts against the plane and the optical axis of the lens group passes through the image sensing unit; when the inner frame moves to the second position, the inner The housing is accommodated in the retreat space. The invention also provides a method for stabilizing components of the optical device.

Description

technical field [0001] The present invention relates to a stabilizing method for an optical device and its components, in particular to a stabilizing method for an optical device and its components which increase the stability of the support between the components with a protruding structure. Background technique [0002] For existing photographic devices, when the camera is turned on and used, the lens of the camera will extend out of the body to receive a small amount of external light. Such a reversible lens group is usually designed to be able to move between the working position and the retracted position and to stably form an image on the image sensor component. When the camera is turned off, each lens group of the lens will overlap with each other and the lens will be retracted into the machine. in the body. As cameras become thinner and thinner, the overall structure requirements are becoming more and more delicate, so the lens groups of the lens are designed to be ...

Problems solved by technology

[0004] see Figure 2-4 , in the above-mentioned known structure, because the first positioning surface 24 and the second positioning surface 34 are all planes, the contact position of the two planes will cause the first positioning surface 24 and the second positioning surface 24 to match the tolerance of the assembly due to the actual machining shape and the assembly tolerance. The contact point of the locating surface 34 may be at the upper end (as figure 2 shown), at the lower end (such as image 3 shown) or the rendering location is indeterminate (such as Figure 4 As shown), the returned position of the inner frame body 20 corresponds to the processing conditions of the components, resulting in an unstable phenomenon, and thus the optical characteristics of the produced lenses are unstable.
