Abstract:
1. A miniature lens auto-focusing structure, comprising: a housing including a top plate which defines a central opening, and being connectable to a base plate to define an inner space between the connected housing and top plate, wherein the top plate is integrally formed with the housing, and has four stepped edges to thereby define a raised ventral portion, and the base plate has a stepped inner circumferential edge to thereby define a recessed central portion; a lens module being wound around by a coil; and a first and a second spring members including an inner movable portion and an outer immovable portion; the first and second spring members being connected at the inner movable portion to the lens module, and the first spring member being connected at the outer immovable portion to the lowest area of the four stepped edges of the top plate, and the second spring member being connected at the outer immovable portion to the highest area of the stepped inner circumferential edge of the base plate, to thereby hold the lens module in the inner space defined between the connected housing and base plate without causing the lens module to contact with the top plate and the base plate, enabling the lens module to suspend in the inner space when the miniature lens auto-focusing structure is in a non-actuated state.
