The guide 230 may be a cylindrical long rod or a polygonal prismatic long rod, and may be adaptively selected according to practical situations. Referring to fig. 1, the polarizer module 300 is fixedly connected with the slider 220, so that when the slider 220 performs linear reciprocating motion along the screw rod, the polarizer module 300 can be synchronously moved under the driving of the slider 220, and thus, the working alternation between the first polarizer 320 and the second polarizer 330 can be realized through the position variation of the polarizer module.

In an alternative embodiment of the present utility model, unlike the above embodiment, the position detecting sensor includes a proximity sensor, specifically, the proximity sensor means that when the distance between the polarizer module 300 and the proximity sensor is greater than a preset distance, the proximity sensor can emit the position information of the polarizer module 300, and it is understood that the proximity sensor does not need to be in direct contact with the polarizer module 300, so that collision or friction between the polarizer module 300 and the sensor can be avoided. There are a wide variety of proximity sensors, for example: electromagnetic proximity sensors, photoelectric proximity sensors, differential transformer proximity sensors, eddy current proximity sensors, capacitive proximity sensors, reed switch proximity sensors, hall proximity sensors, or the like, and specifically, can be adaptively selected according to actual conditions.

It should be noted here that, in order to ensure measurement accuracy, the first position detecting component 410 and the second position detecting component 420 need to be located on the same plane, so that the mounting base 100 on which the first position detecting component 410 and the second position detecting component 420 are mounted needs to ensure a certain flatness, and specifically, the present utility model is not limited herein.

In an alternative embodiment of the present utility model, unlike the above embodiment, the mounting substrate 100 is provided with the flexible circuit board 500, and the first position detecting member 410 and the second position detecting member 420 are both located on the flexible circuit board 500, it is understood that the flexible circuit board 500 is easy to process, and the flatness thereof is easy to meet the installation requirement of the first position detecting member 410 and the second position detecting member 420, so that the overall processing difficulty of the polarizer assembly can be simplified, and the processing and assembling efficiency can be improved.

By providing the connection member 350, the slider 220 and the carrier 310 can be conveniently connected, and the assembly process is simplified, and meanwhile, it can be understood that the connection member 350 can limit a certain space between the slider 220 and the carrier 310, so that the first position detecting component 410 and the second position detecting component 420 can be prevented from being interfered with the slider 220 and the carrier 310, and the spatial position layout of the polarizer assembly can be more reasonable.

In an alternative embodiment of the present utility model, the polarizer module 300 further includes a trigger piece 360, where the trigger piece 360 may include a trigger rod or a trigger piece, and the trigger piece 360 is fixedly connected to the connecting piece 350 and disposed at an angle with respect to the connecting piece 350, and referring to fig. 1, in the embodiment of the present utility model, the trigger piece 360 is disposed perpendicular to the connecting piece 350; the first position detecting member 410 and the second position detecting member 420 are disposed on a moving path of the trigger member 360, and the trigger member 360 is configured to cooperate with the first position detecting member 410 and the second position detecting member 420 to assist in detecting position information of the polarizer module 300 by the first position detecting member 410 and the second position detecting member 420.

Specifically, taking the first position detecting component 410 and the second position detecting component 420 as examples, when the motor slider 220 drives the connecting piece 350 to move, the triggering piece 360 can move along with the movement of the connecting piece 350, when the triggering piece 360 moves to one of the travel switches, the triggering piece 360 contacts with the contact of the travel switch, and further a certain extrusion is generated on the contact, after the contact senses the extrusion, the travel switch can send a signal, and the signal is the position information of the current polarizer module 300.

Specifically, taking the photo-gate type position detecting component 400 as an example, when the motor slider 220 drives the connecting piece 350 to move, the trigger piece 360 can move along with the movement of the connecting piece 350, when the trigger piece 360 moves to one of the photo-gates, the trigger piece 360 can block the optical path of the photo-gate, and when the position detecting component 400 senses that the optical path is blocked, a signal is sent, and the signal is the position information of the current polarizer module 300.

In an alternative embodiment of the present utility model, the polarizer assembly further includes a control part electrically connected to the first position detecting part 410 and the second position detecting part 420 for controlling the operation of the driving part 200 based on the position information of the polarizer module 300 detected by the first position detecting part 410 and the second position detecting part 420.

Taking a lead screw stepping motor 210 with a sliding stroke of 16.5mm as an example in an actual application environment, the maximum sliding stroke of the sliding block 220 along the lead screw in the lead screw stepping motor 210 is 16.5mm, the fixed stroke of the sliding block 220 is 16mm, and accordingly, the preset motor driving step number in the prior art is 800 steps; it will be appreciated that, due to the assembly position of the optocoupler end and the assembly error of other components, the actual running stroke of the polarizer is only 15mm, and the number of driving steps corresponding to 15mm is less than 800, when the slider 220 reaches the 15mm of the actual maximum stroke, the motor will continue to complete the remaining driving steps, that is, the motor will continue to drive the slider 220 to slide, which will cause the slider 220 to generate the wall collision phenomenon, and under the condition that the screw rod is connected with the motor through the elastic member (spring or elastic sheet, etc.), the screw rod will be ejected by 1.5mm under the driving of the slider 220, which will further cause the connection interruption of the screw rod and the motor, resulting in the damage of the polarizer assembly.

When the polaroid module 300 provided by the embodiment of the utility model is applied, the maximum distance between the first position detecting component 410 and the second position detecting component 420 can be limited to be not more than 17mm, so that the limiting block 430 in the first position detecting component 410 and the second position detecting component 420 can limit the actual stroke of the sliding block 220, and the problem that the screw rod is ejected out by 1.5mm is avoided; in addition, the first position detecting component 410 and the second position detecting component 420 are matched with the control component to control the driving component 200 in real time, so that the problem that the sliding block 220 collides with the wall or is blocked can be avoided.

Referring to fig. 1, it can be understood that in the polarizer assembly provided in the embodiment of the present utility model, by providing the first position detecting member 410 and the second position detecting member 420 on the moving path of the polarizer module 300, the position information of the polarizer module 300 is detected by the first position detecting member 410 and the second position detecting member 420, so that when the polarizer module 300 is moved to the position of the first position detecting member 410 or the second position detecting member 420 under the driving of the driving member 200, the control assembly can obtain the position information of the polarizer module 300 at the first time; further, the control component can make a timely response according to the position information and control the next action of the driving component 200, and in the practical application process of the polarizer module 300, the closed-loop control of the driving component 200 can be realized.

Compared with the prior art, in the polarizer assembly provided by the embodiment of the utility model, the rotation step number of the motor can be determined without the preset step number, when the polarizer module 300 reaches the first position detecting component 410 or the second position detecting component 420, the position detecting component 400 can timely transmit the position information of the polarizer module 300 to the control assembly, and the control assembly can timely stop driving or drive the polarizer module 300 to return, so that the phenomenon that the polarizer module 300 and the driving component 200 collide with the wall can be avoided, the blocking phenomenon of the driving component 200 is avoided, and when the polarizer assembly is applied to the network camera equipment, the stability of the network camera equipment can be improved.
