Embodiment Construction

[0024] In the present invention, for the convenience of description, spatially relative terms, such as "on...", "over...", "on the surface of...", "above" and so on, can be used here to describe As shown in the figure, the spatial positional relationship between a device or feature and other devices or features, orientation words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and " The orientation or positional relationship indicated by "top, bottom" and the like are usually based on the orientation or positional relationship shown in the drawings, and the orientation words "inner and outer" refer to the inside and outside relative to the outline of each component itself. The use of orientation words to express the positional relationship is only for the convenience of describing and expressing the positional relationship of the present invention. In the absence of a contrary statement, these orientation words do not indicate or imply...

Abstract

The invention relates to a split-point zoom lens structure, which comprises a lens barrel, wherein a first lens group is arranged at the object side end of the lens barrel, a sliding rod is arranged at the rear end of the first lens group in the lens barrel, a zoom lens group is arranged on the sliding rod, a focusing lens group is arranged at the rear end of the sliding rod, the zoom lens group can move left and right on the sliding rod to realize zooming, the first lens group and the focusing lens group are fixed in the lens barrel to form a prime lens group, the image plane position is notchanged, and the first lens group, the zoom lens group and the focusing lens group are composed of at least one lens. According to the invention, each lens group has a certain light refraction capability, so that the focusing function of the zoom head is realized; the total length of the zoom lens can be limited, so that the zoom lens has better applicability; and the zoom lens is moved by the motor driving the lens group in the lens barrel, so that the zoom lens has a wide application space.

Description

technical field [0001] The invention relates to the field of lens technology, in particular to a split-point zoom lens structure, which can reduce the impact on the lens group after the lens group moves, and is expected to realize a relatively common zoom lens on mobile phones. Background technique [0002] With the development of mobile phone technology, mobile phones have become a necessity in people's daily life. The market's demand for mobile phone lenses is gradually becoming stricter, and the lens must have wide-angle and telephoto performance. At this time, the emergence of zoom lenses meets people's needs for taking pictures in different scenes. In recent years, with the advancement of technology, zoom lenses have gradually been used in high-end mobile phones and have been recognized by the market. However, the zoom lens has problems such as excessive inclination of the lens group during the movement process and stricter tolerance requirements during the manufacturi...
