An auto-focus driving structure for installing a lens has an optical axis. The auto-focus driving structure comprises a main body, a lens retainer, and a driving unit. The lens retainer is movably disposed in the main body. The driving unit includes a coil circuit board and a magnetic group. The coil circuit board has a plurality of printed coils. The plurality of printed coils corresponds to the position of the magnetic group, thus the lens retainer can be selectively moved with respect to a bottom portion of the main body through the driving unit.

A compact auto focus lens module includes a piezoelectric actuator, an elastic element, at least two guiding fixtures, and a lens barrel with an optical lens set therein. By elastic force of the elastic element, a friction is generated between the lens barrel and the piezoelectric actuator. While being applied with a voltage, the lens barrel driven by the movement of the piezoelectric actuator moves along the optical axis under the guidance of the guiding fixtures. Due to fewer elements, compact volume, and light weight, the design is applied to a miniature auto focus lens modules so as to achieve effects of fast movement, stable focusing and reduced tilting.

Compact auto focus lens module with piezoelectric actuator

An auto focus lens module with a piezoelectric actuator having a piezoelectric actuator, a tangent thrust element, a sliding fixture, a metal member, a guiding fixture, and a lens barrel is revealed. By a thrust in the tangent direction generated from the tangent thrust element toward the outer edge of the lens barrel, a friction is generated between the lens barrel and the piezoelectric actuator. When the piezoelectric actuator is applied with a voltage, the lens barrel driven by the piezoelectric actuator moves along an optical axis for focusing with the auxiliary of the guiding fixture. Due to fewer elements, light weight and compact volume, the design is applied to miniature auto focus lens modules so as to achieve effects of fast movement, stable focusing and reduced tilting.

A voice coil driving auto-focus lens module is disclosed. The voice coil driving auto-focus lens module includes a base, two conductive plates, an insulation spacer, four permanent magnets, a lens holder, an optical lens, a spring set, a coil, and a top cover. The lens holder, the optical lens and the coil form a lens set that moves synchronously while the permanent magnets are fixed on an outer circle of a leaf spring. The spring set includes a coil spring and a leaf spring. By resultant spring force due to extension or compression of the coil spring as well as the leaf spring, together with the electromagnetic force, the lens module moves fast, focuses stably and the tilt of the lens module is reduced.

A length-adjustable vehicular power plug for use with a vehicular electrical appliance is disclosed. The vehicular power plug includes a plug end electrically connected to a vehicular power source for getting a power needed for the vehicular electrical appliance; a connector end electrically connected to the vehicular electrical appliance for transmitting the power to the vehicular electrical appliance; a first sleeve body connected to the plug end for supporting the plug end; a second sleeve body connected to the connector end for supporting the connector end, and slipable relative to the first sleeve body; and a positioning member for changing the relative position between the first sleeve body and the second sleeve body from a first position to a second position in response to an external force applied on the first and second sleeve bodies, and securing the first and second sleeve bodies at the second position when the external force is removed, thereby adjusting the length of the vehicular power plug.

Vehicular power plug with adjustable length

A pivot mechanism is arranged between a first portion and a second portion of an appliance. The pivot mechanism includes a first ring member, a first humpback bridge, a positioning base and a shaft. The first ring member is disposed on the first portion and having a first engaging element on the peripheral surface thereof. The first humpback bridge is disposed on the second portion and has a second engaging element on the top surface thereof, wherein the first humpback bridge is resilient and flexible. The positioning base is coupled with the second portion and has a first positioning hole. The shaft is penetrated through the first positioning hole and a center of the first ring member for incorporating the positioning base with the first ring member resting on the first humpback bridge, wherein when any of the first and second portions is pivoted about the shaft to have a specific angle therebetween, the first engaging element temporarily deforms the resilient and flexible first humpback bridge and then engages with the second engaging element to fix the specific angle.
