Problems solved by technology

However, since current flows through both springs when energized, and the spring is a one-piece type so that each part of the spring has current flow, in this way, the possibility of leakage through the spring is greatly increased

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the drawings and embodiments:

[0014] See Figure 1 to Figure 3 A lens module according to an embodiment of the present invention includes a housing, a lens holder 30 installed in the housing for accommodating the lens, a magnet 40 fixed in the housing, a coil 50 wound on the lens holder 30, and A pair of front and rear biasing leaf springs 60, 70.

[0015] The housing includes a base 12, a cover 14, and an iron shell 16 connected between the base 12 and the cover 14. The base 12 and the cover 14 are respectively provided with a plurality of hooks 12a, 14a, the The iron shell 16 is provided with a plurality of buckle holes 16 a to buckle with the hooks 12 a and 14 a respectively, so that the iron shell 16 is fixed between the base 12 and the cover 14. The iron shell 16 has a square shape, and the number of magnets 40 is four, which are respectively fixed to the four corners of the iron shell 16. Ea...

Abstract

The invention relates to a lens module group, which comprises a housing, a lens holder used for containing lenses and a driving part which are arranged in the housing; wherein the driving part comprises a magnet fixed either in the housing or in the lens holder and a coil fixed either in the housing or in the lens holder; the lens module group also comprises an eccentrically pressed leaf spring which comprises at least three separating parts; power is supplied to the coil by two separating parts; each separating part comprises an attaching part attached to the lens holder, a fixing part fixedto the housing and an elastic part connected between the attaching part and the fixing part. As only two parts of the eccentrically pressed leaf springs are electrified, the lens module group greatlyreduces the possibility of electric leakage.

Description

Technical field [0001] The present invention relates to the field of camera technology, in particular to a lens module. Background technique [0002] With the popularity of mobile phones and the diversification of their functions, mobile phones with cameras will have more and more broad market prospects. The existing auto-focus mobile phones on the market usually use electromagnetic induction motors, which have the advantages of high speed and high efficiency, but the disadvantages are that the positioning accuracy is not high, it cannot be quickly self-locked, and it is difficult to miniaturize. It is not suitable for current mobile phones. The camera is getting smaller and smaller. [0003] The voice coil motor supports lens expansion and contraction by means of reeds, which can realize smooth and continuous lens movement. Due to its small size and simple structure, it has been widely used in lens modules of mobile phones. For example, US Patent Publication No. 7,298,562 disclo...
