Abstract

The utility model relates to a lens telescopic structure which comprises a basal seat, a driving component and an imaging lens set, wherein the inner part of the basal seat forms a plurality of containing spaces and positioning components. The driving component is arranged in each containing space of the basal seat, and is provided with a driving motor and a linking piece. The driving motor is used for supplying a dynamic source, and the linking piece is provided with a spur gear and a linking part. The spur gear is connected with the driving motor, and is moved by the driving motor. The linking part is formed at the position of one side of the spur gear, and is moved with the spur gear. The imaging lens set is arranged in each containing space of the basal seat, and is sheathed in positioning components. The imaging lens set is abutted on the linking part. When the driving motor acts, the imaging lens set simultaneously drives the spur gear and the linking part, and the abutting on position between the linking part and the imaging lens set is changed. Thereby, the imaging lens set can carry out a reciprocating displacement between a first position and a second position.

Embodiment

Seeing also Figure 1 and Figure 2, is a kind of camera lens stretching structure 100 that the utility model one preferred embodiment is provided, and it consists predominantly of a pedestal 10, a driven unit 20, an imaging lens group 30 and a sensor 40, wherein:

This pedestal 10, have one first housing 11 and one second housing 12, this first and second housing the 11, the 12nd, can be covered mutually and snapping or in addition the application of force separate, and this first and

second housing

11,12 is laid with some positioning components and accommodation space simultaneously in the pre-position, is installed with for other constituent components.

This driven unit 20 has a CD-ROM drive motor 21, a connection piece 22, a Transmission Part 23 and a moving part 24; Wherein, this CD-ROM drive motor 21 is the drive motor of a microminaturization, by ccontaining and be fixed in the accommodation space of this pedestal 10, and this end has a spur gear rotor 211 that is connected with motor rotor, is can be subjected to the effect of this CD-ROM drive motor 21 and revolver synchronously; This web member 22 is a splicing ear, is to be electrically connected on this CD-ROM drive motor 21, and partly is exposed to outside this pedestal 10; This Transmission Part 23 is to be connected on the part that this web member 22 exposes, can be connected with other control circuit, in order to the signal of transmission controlling and driving motor 21 starts to this CD-ROM drive motor 21; This moving part 24 has a spur gear 241, a locating shaft 242 and a linkage part 243, this locating shaft 242 is the places, both sides, axle center that are formed at this spur gear 241, this locating shaft 242 can be penetrated the one end in a pilot hole of this CD-ROM drive motor 21, and with other end set in a recess of this pedestal, so that this spur gear 241 is positioned in this pedestal 10, and make this spur gear form state of interlocking mutually with this spur gear rotor 21 just 241 this moments, and can rotate transmission mutually in the original place; This linkage part 243 is to be formed on this locating shaft 241, and the position is at a side place of this spur gear 241, be that a ring is located at the bulge loop on this locating shaft 241, and this linkage part 243 has is interrupted not junction, and make this linkage part 243 by its thickness the thinnest a bit toward another some circle around the time be to be the kenel of thickening its thickness gradually.

This imaging lens group 30 has a camera lens main body 31, two sleeves 32, a Passive part 33 and one tested 34; This two sleeve 32 is to be formed on the precalculated position, both sides of this camera lens main body 31, and directly be set in respectively on these pedestal 10 first housings 11 formed two projections 111, make this camera lens main body 31 carry out reciprocal displacement toward polyslip with moving along this projection 111 by this sleeve 32; This Passive part 33 is to be convexly set in outside the sleeve 32 of one, and is resisted against on the linkage part 243 of this moving part 24; This tested 34 is to be convexly set in outside this camera lens main body 31.

This sensor 40, be to be arranged in the accommodation space of this pedestal 10, can be in order to the place, tested 34 position of this imaging lens group 30 of sensing, and then signal transferred to by a Transmission Part (not shown) that is connected with this sensor 40 in the extraneous control circuit.

Be with, above-mentioned be the utility model provide a preferred embodiment camera lens stretching structure 100 the main composition important document and form kenel, then be described below as flowing mode of the present utility model again:

At first, see also Fig. 3 and shown in Figure 4, when desire becomes the state of outwards upholding (to obtain suitable imaging) (shown in the 4th figure) with this camera lens main body 31 by the interior state that contracts (as shown in Figure 3) change, at first the control circuit by the external world is input into signal or power in this web member 22 and this CD-ROM drive motor 21 by this Transmission Part 23, this moment, this CD-ROM drive motor 21 just can entry into service, and then drive this spur gear rotor 211 and rotate synchronously, and when this spur gear rotor 211 rotates, also can drive this spur gear 241 simultaneously rotates synchronously, make this be resisted against this locational Passive parts 33 of linkage part 243 thinner thicknesses (as shown in Figure 3) originally, can change on the linkage part 243 that is resisted against thicker position (as shown in Figure 4) because of the rotation of this spur gear 241, thus, when this Passive part 33 gradually by the linkage part 243 that is resisted against thin position on (this moment, Passive part was apart from the axle center close together of locating shaft) and when changing on the linkage part 243 that is resisted against thicker position (this moment Passive part apart from the distance of shaft centers of locating shaft from far away), this sleeve 32 also can be subjected to the drive of this Passive part 33 and begin to carry out slippage along this projection 111, (31 can be driven and be moved on the second place (extratensive type attitude) by this sleeve 32 in the camera lens main body of a primary importance (recessed shape attitude) state to make former one's own department or unit, when this sensor 40 senses this position of tested 34 is when representing this camera lens main body 31 to arrive preposition, this sensing member 40 can be sent signal to the control circuit in the external world, extraneous control circuit can be assigned the signal that stops these CD-ROM drive motor 21 runnings to this CD-ROM drive motor 21 by this Transmission Part 23, make this camera lens main body just can keep fixing state 31 this moments, with demand in response to the user.

When user's desire moves to primary importance (recessed shape attitude) with camera lens main body 31 by the second place (extratensive type attitude), just impel this CD-ROM drive motor 21 counter-rotatings, and linkage part 243 is rotated, this Passive part 33 is resisted against on the linkage part 243 of thin position once again, thus, just can drive this camera lens main body 31 by this sleeve 32 again is moved on the primary importance.

Because the utility model is between CD-ROM drive motor and camera lens main body, be to adopt spur gear to be cooperated transmission, therefore in the process of this camera lens main body displacement, just can be by the preferable factor effect of this spur gear run stability, and make this camera lens main body can be stably in addition displacement; And, and can reduce the cost on making because spur gear has the comparatively cheap characteristic of manufacturing cost compared to other tooth kind; And owing to utilize the cooperation transmission of spur gear, can make the required space reduction of holding gear, and can make the in addition miniaturization more of whole volume.
