Further, the inside of unable adjustment base is equipped with installation space, and the carrier setting is in installation space, unable adjustment base's both ends are the starting point and the end that the carrier removed respectively.

Furthermore, the carrier is movably arranged in the fixed base, a first installation groove used for installing the first lens is formed in one end of the carrier, and a second installation groove used for installing the second lens is formed in the other end of the carrier.

Furthermore, two sides of the carrier are respectively provided with an open slot, the guide sleeve is arranged in the open slot, the short guide post penetrates through the guide sleeve, and the carrier moves along the short guide post.

Furthermore, the device also comprises a piezoelectric motor, wherein the output end of the piezoelectric motor is connected with the carrier and can push the carrier to move along the guide post.

A photographic apparatus has the lens driving apparatus of the above-described structure.

An electronic device having the photographic apparatus of the above-described structure.

In conclusion, the invention has the following beneficial effects:

by adopting the double guide columns, the length of a single guide column and the width of the guide sleeve are greatly shortened, the internal space wrapped by the lens driving device is saved while the same function is provided, the machining error is reduced due to the shortened length of the guide column/the guide sleeve, the mirror carrier is ensured not to incline in the process of moving along the guide column, and the unidirectional straightness of the mirror carrier moving is ensured.

Detailed Description

In order to make the technical means, the original characteristics, the achieved purposes and the effects of the invention easy to understand, the invention is further described with reference to the figures and the specific embodiments.

As shown in FIGS. 1 to 3, the lens driving device of the present invention comprises a fixed base 1, a guide post 2 disposed on the fixed base 1,

And a carrier 4 sleeved on the guide post 2 through the guide sleeve 3;

the guide posts 2 are short guide posts, and two sides of the fixed base 1 are respectively provided with a short guide post, wherein one short guide post is arranged at the front half section of the stroke of the carrier 4, and the other short guide post is arranged at the rear half section of the stroke of the carrier 4.

Example 1

A lens driving device comprises a fixed base 1, a guide post 2 arranged on the fixed base 1, and a carrier 4 sleeved on the guide post 2 through a guide sleeve 3; the guide posts 2 are short guide posts, and two sides of the fixed base 1 are respectively provided with a short guide post, wherein one short guide post is arranged at the front half section of the stroke of the carrier 4, and the other short guide post is arranged at the rear half section of the stroke of the carrier 4.

In this embodiment, the fixing base 1 is provided with an installation space 11 inside, the carrier 4 is disposed in the installation space 11, and the two ends of the fixing base 1 are respectively the starting end and the tail end of the movement of the carrier 4.

In this embodiment, the carrier 4 is movably disposed in the fixing base 1, a first mounting groove 41 for mounting a first lens is disposed at one end of the carrier 4, and a second mounting groove 42 for mounting a second lens is disposed at the other end of the carrier 4. An open slot 43 is respectively arranged on two sides of the carrier 4, the guide sleeve 3 is arranged in the open slot 43, the short guide post penetrates through the guide sleeve 3, and the carrier 4 moves along the short guide post.
