Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, an embodiment of the present utility model is, a kind of pair of optical-filter switcher, and as shown in Figure 2, it comprises top cover 1 and base 7; Described top cover is fixedly installed in described base, forms an inner chamber between the two; Described top cover arranges an imaging lens; Be provided with screw mandrel 2, motor 3, white glass 4, IR-cut glass 5 and glass balladeur train 6 in described inner chamber; As shown in Fig. 3,4, described screw mandrel, described motor are fixedly installed in respectively described base, and described glass balladeur train slides and is arranged at described base; Described base is provided with installation site 401 and the installation site 402 that adapts to described screw mandrel, described motor.As shown in Figure 3, described white glass and described IR-cut glass are installed on described glass balladeur train side by side; As shown in Figure 4, described glass balladeur train is provided with and is respectively used to embed two installation sites, place that described white glass and described IR-cut glass are installed.Preferably, described white glass and described IR-cut glass adopt the back-off mode to be arranged on described glass balladeur train.Preferably, described white glass and described IR-cut glass also adopt adhesive means to be fixed on described glass balladeur train.
As shown in Figure 4, described glass balladeur train arranges a slide block 201, and preferred, described slide block and described glass balladeur train are wholely set.Described screw mandrel arranges a groove, is generally the thread-shaped chute, and described slide block and the adaptive setting of described silk groove are used for when described screw mandrel rotates, and described silk groove rotates and drive described slide block translation, makes described glass balladeur train generation translation; Preferably, described slide block arranges the square-section, and perhaps, described slide block arranges the trapezoid cross section, and perhaps, described slide block arranges the triangular-section; Perhaps, described slide block arranges the expansion end, and described silk groove is corresponding adaptive arranges expansion chamber section, is used for accommodating described expansion end, and the described slide block of dismounting when stressed.Preferably, the described pair of optical-filter switcher arranges the axial consistent of described screw mandrel and described motor, and consistent with the translation direction of described glass balladeur train.
As shown in Figure 4, the two ends of described silk groove arrange respectively a limiting section, are used for limiting the translation of described slide block, slide block translation when namely the silk groove rotates, and slide block stops when moving to the limiting section place; As shown in Fig. 5 A and Fig. 5 B, the two ends of described silk groove arrange respectively a limiting section 101 and a limiting section 102, and slide block 201 stops when moving to limiting section 101 or limiting section 102 place.
Preferably, as shown in Fig. 5 A and Fig. 5 B, the two ends of described screw mandrel arrange respectively a lock part 301 and lock part 302, are used for when described slide block moves to the corresponding end of described silk groove the described screw mandrel of locking.When slide block 201 moves to limiting section 101, touch simultaneously lock part 301, perhaps, when slide block 201 moves to limiting section 102, touch simultaneously lock part 302, thereby stop screw mandrel to rotate, block motor this moment, do not allow it rotate, adopt the extremely short pulse electric current of drive motor due to motor, therefore can not cause electrical fault.
as shown in Figure 4, described screw mandrel is fixedly mounted on the turning axle of described motor, be used for following electric machine rotation, as shown in Fig. 5 A, drive described glass balladeur train to the first end translation of described silk groove when the motor forward rotation, when making described glass balladeur train move to described first end, white glass is over against described imaging lens, remove described glass balladeur train, the structure of this moment is as shown in Fig. 5 B, driving described glass balladeur train when the motor backward rotation holds level with both hands to second of described silk groove and moves, when making described glass balladeur train move to described first end, IR-cut glass is over against described imaging lens.
Another example, as shown in Fig. 6 A and Fig. 6 B, it is that A-A face cut-open view, B-B face cut-open view, C-C face cut-open view are respectively as Fig. 7 A, Fig. 7 B, shown in Figure 8; The enlarged diagram of Fig. 8 as shown in Figure 9, its principle of work as shown in Figure 3, this switch is opened the state of top cover.Screw mandrel 2 wringing fits are contained on the turning axle of motor 3, when motor 3 rotates, screw mandrel 2 is followed rotation, driving assembly has glass balladeur train 6 to-and-fro movements of white glass 4 and IR-cut glass 5, make glass balladeur train 6 white glass 4 when an end of switch align the imaging lens that is assemblied on top cover 1, and IR-cut glass 5 align the imaging lens that is assemblied on top cover 1 when glass balladeur train 6 switches to the other end of switch during the motor backward rotation.Preferably, described white glass is full spectrum optical glass.
Current like product on the market is all larger, and the utility model has been realized this function in less volume, and has reduced material and assembly cost.White glass 4 and IR-cut glass 5 are contained on glass balladeur train 6 by the form of back-off, have avoided beating the defective that the wayward glue of glue flows everywhere.Axially screw mandrel 2 and motor 3 arrangement modes consistent with glass balladeur train 6 direction of motion, make whole transmission very compact, obtains less volume.
As shown in Fig. 5 A and Fig. 5 B, the two ends limited location section of the silk groove on screw mandrel 2, for example limiting section is vertical plane, the stroke of restriction slide block, simultaneously the upper and lower surface at the slide block 201 places plane of encountering screw mandrel lock part place stops screw mandrel to rotate, this moment the stall motor, extremely short pulse current due to drive motor, can not cause electrical fault, ingeniously realize that compactly ram travel puts in place, simultaneously again can be not stuck.And there is stuck problem in like product on the market, has perhaps solved stuck problem but the complicated difficulty of making of mechanism, and quality is wayward.And, owing to existing lock part to coordinate self-locking with slide block between screw mandrel 2 and slide block 6, can effectively stop and fall and slide block displacement when knocking, thereby avoid utilizing on the market the mode of solenoid valve fork all to exist falling and the shortcoming of slide block displacement when knocking.
Further, embodiment of the present utility model can also be, each technical characterictic of the various embodiments described above, the two optical-filter switchers that mutually are combined to form.
Need to prove, above-mentioned each technical characterictic continues combination mutually, forms the various embodiment that do not enumerate in the above, all is considered as the scope of the utility model instructions record; And, for those of ordinary skills, can be improved according to the above description or conversion, and all these improve and conversion all should belong to the protection domain of the utility model claims.
