Lens driving device

A lens driving device, comprising:

• a lens support for retaining a lens, a side of an object to be shot being taken as a front side of an optical axis of the lens;
• a driving coil configured on an outer side of the lens support and configured for enabling the lens support to move along the optical axis;
• an upper side fixing body configured above the lens support;
• a lower side fixing body configured below the lens support;
• an upper spring configured for connecting the lens support with the upper side fixing body and supporting the lens support to be capable of moving along the optical axis;
• a lower spring configured for connecting the lens support with the lower side fixing body and supporting the lens support to be capable of moving along the optical axis;
• wherein the lens support comprises a plurality of protruding parts formed below the driving coil and protruding outwards from the lens support;
• wherein an upper surface of each protruding part defines a first clamping part;
• wherein a plurality of vertical direction limiting parts are configured on a lower surface of the upper side fixing body, the plurality of vertical direction limiting parts abut against the plurality of first clamping parts so as to limit an amount of movement of the lens support along the optical axis;
• wherein under the condition that the driving coil is not driven, the plurality of first clamping parts of the lens support and the plurality of vertical direction limiting parts of the upper side fixing body are mutually partitioned at a preset interval.
