Abstract

The invention discloses a cap module of an optical lens, which comprises a fixing seat, a lens cap and a driving unit. The fixing seat comprises an opening, and the lens cap can move along the longitudinal direction to open or close the opening; the lens cap comprises a first triggering part and a second triggering part which is arranged in the longitudinal direction and is spaced with the first triggering part. The driving unit comprises a motor, a transmission part connected between the motor and the lens cap, and a bidirectional switch. The bidirectional switch is provided with a toggling part arranged between the first triggering part and the second triggering part. When the first triggering part triggers the toggling part, the opening opens completely and the bidirectional switch impels the motor to stop working. When the second triggering part triggers the toggling part, the opening closes entirely and the bidirectional switch impels the motor to stop working.

Description

The cap module of optical lens

Technical field

The present invention relates to a kind of cap module of electronic running, particularly a kind of cap module of optical lens.

Background technology

No. 512255th, TaiWan, China patent announcement and No. M377043rd, certificate all disclose a kind of cap module of electronic running, both are to possess two aware switch at main technical requirement, one of them aware switch is used for the location status that perception lens cap is opened completely, another aware switch is used for the complete totally enclosed location status of this lens cap of perception, motor be then via these aware switch sensing results so that decommission, but, when using two aware switch, the complexity of structural design is still higher, be unfavorable for product miniaturization and light-weighted demand, manufacturing cost is also not easy to reduce.

Summary of the invention

The technical problem to be solved in the present invention is, for cap module in prior art need employing two aware switch, complexity higher, be unfavorable for the miniaturized and light-weighted defect of product, provide a kind of and can reduce manufacturing cost, structure complexity reduces, be conducive to the cap module of the miniaturized and light-weighted optical lens of product.

The technical scheme that the present invention adopts for its technical problem of solution provides a kind of cap module of optical lens, comprises holder, lens cap, and driver element.

This holder comprises opening.

This lens cap can move and this opening of opening and closing of fault along length direction, and this lens cap comprises the first trigger unit, and is interval in the second trigger unit of this first trigger unit along this length direction.

This driver element comprises motor, be connected to driving member between this motor and this lens cap, and two-way switch, and this two-way switch has the clicking section between this first trigger unit and this second trigger unit.

Wherein, this lens cap moves until when this first trigger unit touches this clicking section, and this opening is in opening completely, and this two-way switch output signal impels this motor to decommission.

Wherein, this lens cap moves until when this second trigger unit touches this clicking section, and this opening is in completely closed, and this two-way switch output signal impels this motor to decommission.

Beneficial effect of the present invention is: during manufacture, owing to only needing a two-way switch, so the complexity of hardware configuration can reduce, is conducive to product miniaturization and light-weighted requirement, and reaches the substantial effective reducing manufacturing cost.

Detailed description of the invention

Aforementioned and other technology contents, feature and effect for the present invention, in the detailed description of the preferred embodiment of following cooperation accompanying drawing, can clearly present.

As shown in Figure 1, 2, 3, the preferred embodiment of the cap module 200 of optical lens of the present invention comprises holder 20, lens cap 30, and driver element 40, and this cap module 200 is be applied in projector's (not shown) at the present embodiment.

This holder 20 comprises two guide rails 21 being parallel to length direction X and extending, and the opening 22 for corresponding optical lens (not shown) and between these guide rails 21.

This lens cap 30 can move and this opening 22 of opening and closing of fault along this length direction X, this lens cap 30 comprises the multiple slide block 31, tooth bar 32, first trigger unit 33 that extends along this length direction X that are slidedly arranged on these guide rails 21 respectively, and is interval in the second trigger unit 34 of this first trigger unit 33 along this length direction X.

Wherein two two ends being connected to this tooth bar 32 of these slide blocks 31.

This first trigger unit 33 protrudes extension from these slide blocks 31 respectively in opposite directions with this second trigger unit 34.

This driver element 40 is arranged at this holder 20, and comprise motor 41, be connected to driving member 42 between this motor 42 and this lens cap 30, and two-way switch 43.

This driving member 42 is engaged in this tooth bar 32 and drives via this motor 41, this driving member 42 adopts worm screw in the present embodiment, also gear (not shown) can be adopted during actual manufacture, what deserves to be explained is, except this tooth bar 32 and the combination of this worm screw (or gear), other mechanism can also be adopted to drive this lens cap 30, the combination (not shown) of such as rope and bull wheel, this rope is tied to this lens cap 30 winding on this bull wheel rotated by this motor 41.

This two-way switch 43 has the clicking section 431 between this first trigger unit 33 and this second trigger unit 34.

The use situation of this cap module 200 will be further illustrated below, when this motor 41 drives this lens cap 30 to move until when this first trigger unit 33 touches this clicking section 431, this clicking section 431 is stressed towards a side oscillation, this opening 22 is in opening completely, and this two-way switch 43 output signal impels this motor 41 to decommission.

As shown in Figure 4,5, when this motor 41 drives this lens cap 30 to move, when making this opening 22 close gradually or open gradually, because this first trigger unit 33 does not all touch this clicking section 431 with this second trigger unit 34, therefore this clicking section 431 is held in center state without any beat, and this motor 41 also can continued operation.

As shown in Figure 6,7, when this motor 41 drives this lens cap 30 to move until when this second trigger unit 34 touches this clicking section 431, this clicking section 431 is stressed to be swung towards opposite side, and this opening 22 is in completely closed, and this two-way switch 43 output signal impels this motor 41 to decommission.

By this, during manufacture, owing to only needing a two-way switch 43, so the complexity of hardware configuration can reduce, be conducive to product miniaturization and light-weighted requirement, overall manufactures instinct compared to designing minimizing in the past, reaches and reduces manufacturing cost substantial effective.

The foregoing is only preferred embodiment of the present invention, can not limit scope of the invention process with this, namely all simple equivalences done according to the claims in the present invention and description change and modify, and all still remain within the scope of the patent.
