Description

Technical Field

[0001] The present invention relates to the technical field of switching devices, and particularly to a dual filter switcher. Background Art

[0002] Common ICR (dual filter) switchers on the market require at least two filters, one being an IR filter (during the day) and an AR or other filter (for night vision), which are assembled and attached to a carrier for lateral displacement. In common designs, at least three times the size space of the filters is required to achieve the switching function, so the occupied space is relatively large. Summary of the Invention

[0003] The present invention discloses a dual filter switcher to solve the problem that the dual filter switcher in the prior art occupies a large space.

[0004] To achieve the above object, an embodiment of the present invention discloses a dual filter switcher, comprising:

[0005] A housing, the housing encloses to form an installation cavity, and a through hole communicating with the installation cavity and penetrating the housing is provided on the housing;

[0006] A first filter assembly, the first filter assembly is installed in the installation cavity, the first filter assembly includes a first filter, and the first filter has a first filtering position facing the through hole and a first avoiding position misaligned with the through hole;

[0009] Since the first filter component and the second filter component in the dual-filter switch of the present invention are stacked in the installation cavity, when actually designing the housing, the lateral direction of the housing only needs to be able to accommodate the sum of the lateral widths of the first filter component and the second filter component. Compared with the structure in the prior art that needs to set the lateral width of 3 times the filter, the lateral width of the housing in the present invention can be set to only the sum of the lateral widths of the first filter component and the second filter component, which can reduce the occupied space of the dual-filter switch and facilitate the miniaturization design of the dual-filter switch.

By arranging the first filter component and the second filter component in two cavities respectively, when the driving component drives the first filter component and the second filter component to perform filter switching, it is not easy to interfere and collide with each other, and the structure is more stable and reliable.

[0015] During the sliding process of the first bearing part, the upper and lower sides of the first slideway are respectively a first slide table and a partition plate. The first slide table and the partition plate can limit the first bearing part from the upper and lower sides of the first bearing part, preventing the first bearing part from bouncing during the sliding process, making the movement more stable and reliable, and reducing the noise during the use of the dual filter switch.

The partition plate contacts the first filter assembly through the first protrusions. That is to say, the partition plate contacts the first bearing part through the first protrusions, which can reduce the contact area between the first bearing part and the partition plate, thereby reducing the friction between the first bearing part and the partition plate, and can limit the first bearing part on the first slide table, effectively preventing the first bearing part from bouncing on the first slide table.

[0058] The following will be described in detail with reference to the accompanying drawings.

[0059] See Figures 1 to 4 and Figure 7 As shown in

[0060] According to an embodiment of the present invention, a dual filter switcher is provided. The dual filter switcher includes a housing 10, a first filter assembly 30, a second filter assembly 40, a driving assembly 80, and a power cord 90.

[0061] It can be understood that the stacked arrangement of the first filter assembly 30 and the second filter assembly 40 in this embodiment may refer to the way that the first filter assembly 30 and the second filter assembly 40 are arranged parallel to each other vertically or horizontally in the installation cavity. Figure 4 The way that the first filter assembly 30 and the second filter assembly 40 are arranged parallel to each other vertically is shown. During actual operation, the power cord 90 supplies power to the drive assembly 80. When the first driving part drives the first filter 32 to switch to the first filtering position, the second driving part simultaneously drives the second filter 42 to switch to the second avoidance position. At this time, the first filter 32 performs the filtering function. Correspondingly, when the first driving part drives the first filter 32 to switch to the first avoidance position, the second driving part simultaneously drives the second filter 42 to switch to the second filtering position. At this time, the second filter 42 performs the filtering function.

[0062] Since the first filter assembly 30 and the second filter assembly 40 in the dual-filter switch of this embodiment are stacked in the installation cavity, when actually designing the housing 10, the lateral direction of the housing 10 only needs to be able to accommodate the sum of the lateral widths of the first filter assembly 30 and the second filter assembly 40. Compared with the structure in the prior art that needs to set the lateral width of 3 times the filter, the lateral width of the housing 10 in this embodiment can be set to only the sum of the lateral widths of the first filter assembly 30 and the second filter assembly 40, which can reduce the occupied space of the dual-filter switch and facilitate the realization of the miniaturized design of the dual-filter switch.

[0063] Optionally, one of the first filter 32 and the second filter 42 in this embodiment is an IR filter, and the other is an AR filter or other night vision filters, so that the dual-filter switch of the present invention is convenient to be applied to the camera module.

[0064] In some embodiments of the present invention, the housing 10 includes a bottom case 11 and an upper cover 12. The upper cover 12 can be fixed to the bottom case 11 through structures such as snaps, screws, pins, bolts, etc. The upper cover 12 and the bottom case 11 enclose to form an installation cavity, which is convenient for installing the first filter assembly 30, the second filter assembly 40, the drive assembly 80, etc., and preventing the adverse effects such as pollution on the first filter assembly 30, the second filter assembly 40, and the drive assembly 80 caused by the external environment.

[0065] Specifically, the through hole 101 in this embodiment penetrates through the bottom case 11 and the upper cover 12, ensuring that the light incident on the through hole 101 can penetrate the housing 10 after being filtered by the first filter 32 and the second filter 42, realizing an effective light filtering function. Optionally, the housing 10 in this embodiment can be arranged in a prismatic shape, a cylindrical shape, an elliptical cylindrical shape, a polygonal cylindrical shape, or other special-shaped cylindrical structures, and can be specifically adjusted and set according to the actual application scenario of the dual-filter switcher, which is not specifically limited in this application, as long as the first filter assembly 30, the second filter assembly 40, and the driving assembly 80 can be installed.

[0066] In some embodiments of the present invention, the dual-filter switcher further includes a partition plate 20, which is fixed to the housing 10 and divides the installation cavity into a first cavity 60 and a second cavity 70. A light passing hole 21 corresponding to the through hole 101 is provided on the partition plate 20 (see Figure 5 shown). The setting of the light passing hole 21 ensures that the first filter 32 and the second filter 42 can perform normal light filtering functions and prevents the partition plate 20 from blocking the light entering the installation cavity. During actual installation, the first filter assembly 30 is arranged in the first cavity 60, and the second filter assembly 40 is arranged in the second cavity 70. By arranging the first filter assembly 30 and the second filter assembly 40 in two cavities respectively, when the driving assembly 80 drives the first filter assembly 30 and the second filter assembly 40 to perform light filtering switching, it is not easy to cause mutual interference and collision, and the structure is more stable and reliable.

[0067] Specifically, the partition plate 20 is fixed to the bottom case 11 through a fastening component, and the partition plate 20 and the bottom case 11 enclose to form the first cavity 60, and the partition plate 20 and the upper cover 12 enclose to form the second cavity 70. The structure is simple and convenient for disassembly and assembly.

[0068] In some embodiments of the present invention, the fastening component for fixing the partition plate 20 can be at least one of a screw, a snap component, a bolt, and a pin. Figure 2 shows the structure of fixing the partition plate 20 to the bottom case 11 by using a snap component. Specifically, the snap component in this embodiment includes a snap 25 and a hook 114, where one of the snap 25 and the hook 114 is arranged on the partition plate 20, and the other is arranged on the bottom case 11. Through the cooperative connection of the snap 25 and the hook 114, the partition plate 20 can be quickly fixed on the bottom case 11. Optionally, there are multiple snap components in this embodiment, and the multiple snap components are arranged along the outer periphery of the partition plate 20, which can improve the installation stability and reliability of the partition plate 20.

[0069] Please refer to Figures 3 to 6As shown, the first filter component 30 further includes a first carrier portion 31, and the first filter 32 is disposed on the first carrier portion 31, facilitating the installation of the first filter 32. During actual operation, the first carrier portion 31 slides within the first cavity 60, which can drive the first filter 32 to move between the first filtering position and the first avoidance position. Optionally, the first carrier portion 31 in this embodiment is a carrier plate, with a simple structure and a relatively thin thickness, which can further reduce the volume of the dual-filter switch. Of course, in other embodiments of the present invention, the first carrier portion 31 can also be configured as a carrier column, a carrier block, or other structures capable of installing the first filter 32.

[0070] To enable the first carrier portion 31 to slide within the first cavity 60, a first sliding platform 111 is provided within the bottom case 11 in this embodiment. Specifically, it can be disposed on the inner side wall surface of the bottom case 11 or on the bottom of the inner cavity of the bottom case 11. The extending direction of the first sliding platform 111 is parallel to the radial direction of the light passing hole 21 (i.e., perpendicular to the axial direction of the light passing hole 21). The first sliding platform 111 is parallel to the partition plate 20, and a first sliding track is formed by enclosing between the first sliding platform 111 and the partition plate 20. During actual installation, the first carrier portion 31 is disposed in the first sliding track and slides along the first sliding track under the drive of the first driving portion, thereby driving the first filter 32 to switch between the first filtering position and the first avoidance position. During the sliding process of the first carrier portion 31, the upper and lower sides of the first sliding track are the first sliding platform 111 and the partition plate 20 respectively. The first sliding platform 111 and the partition plate 20 can limit the first carrier portion 31 from the upper and lower sides of the first carrier portion 31, preventing the first carrier portion 31 from jolting during the sliding process, making the movement more stable and reliable, and reducing the noise during the use of the dual-filter switch.

[0071] Similarly, the second filter component 40 in this embodiment further includes a second carrier portion 41, and the second filter 42 is disposed on the second carrier portion 41, facilitating the installation of the second filter 42. During actual operation, the second carrier portion 41 slides within the second cavity 70, which can drive the second filter 42 to move between the second filtering position and the second avoidance position. Optionally, the second carrier portion 41 in this embodiment is a carrier plate, with a simple structure and a relatively thin thickness, which can further reduce the volume of the dual-filter switch. Of course, in other embodiments of the present invention, the second carrier portion 41 can also be configured as a carrier column, a carrier block, or other structures capable of installing the second filter 42.

[0072] In order to enable the second bearing part 41 to slide in the second cavity 70, a second sliding table 121 is provided on the upper cover 12 in this embodiment. Specifically, it can be provided on the side wall of the upper cover 12 close to the installation cavity. The extending direction of the second sliding table 121 is parallel to the radial direction of the light passing hole 21 (i.e., perpendicular to the axial direction of the light passing hole 21). The second sliding table 121 is parallel to the partition plate 20 and can enclose a second sliding track with the partition plate 20. During actual installation, the second bearing part 41 is arranged in the second sliding track and slides along the second sliding track under the drive of the second driving part, so as to drive the second filter 42 to switch between the second filtering position and the second avoiding position. During the sliding process of the second bearing part 41, the upper and lower sides of the second sliding track are the second sliding table 121 and the partition plate 20 respectively. The second sliding table 121 and the partition plate 20 can limit the second bearing part 41 from the upper and lower sides of the second bearing part 41 to prevent the second bearing part 41 from bouncing during the sliding process, making the movement more stable and reliable, and reducing the noise during the use of the dual-filter switch.

[0073] Further, a plurality of first protrusions 23 are provided on the side of the partition plate 20 close to the first cavity 60. The partition plate 20 contacts the first filter assembly 30 through the first protrusions 23, and specifically can abut against the first bearing part 31. That is to say, the partition plate 20 contacts the first bearing part 31 through the first protrusions 23, which can reduce the contact area between the first bearing part 31 and the partition plate 20, thereby reducing the friction between the first bearing part 31 and the partition plate 20, and can limit the first bearing part 31 on the first sliding table 111, effectively preventing the first bearing part 31 from bouncing on the first sliding table 111.

[0074] Similarly, a plurality of second protrusions 24 are provided on the side of the partition plate 20 close to the second cavity 70. The partition plate 20 contacts the second filter assembly 40 through the second protrusions 24, and specifically can abut against the second bearing part 41. That is to say, the partition plate 20 contacts the second bearing part 41 through the second protrusions 24, which can reduce the contact area between the second bearing part 41 and the partition plate 20, thereby reducing the friction between the second bearing part 41 and the partition plate 20, and can limit the second bearing part 41 on the second sliding table 121, effectively preventing the second bearing part 41 from bouncing on the second sliding table 121.

[0075] Please refer to Figure 6 and Figure 7As shown, the drive assembly 80 in this embodiment further includes an electromagnetic coil module 83. The electromagnetic coil module 83 has a first end 8301 and a second end 8302 opposite to the first end 8301. During actual installation, the electromagnetic coil module 83 is installed in the installation cavity, specifically, it can be installed in the first cavity 60 or the second cavity 70. The drawings in this application show the case where the electromagnetic coil module 83 is installed in the first cavity 60, that is, installed in the bottom shell 11. Further, the first drive part is located at the first end 8301 of the electromagnetic coil module 83, and the second drive part is located at the second end 8302 of the electromagnetic coil module 83 opposite to the first end 8301. The first drive part includes a first magnetic lever 81, and the first magnetic lever 81 is drivingly connected to the first filter assembly 30. The second drive part includes a second magnetic lever 82, and the second magnetic lever 82 is drivingly connected to the second filter assembly 40. Among them, when a pulsed current is applied to the electromagnetic coil module 83, the first magnetic lever 81 moves under the action of the magnetic field force applied by the electromagnetic coil module 83, and can drive the first filter assembly 30 to move, so as to drive the first filter 32 to switch from the first filtering position to the first light-shielding position. At the same time, the second magnetic lever 82 moves under the action of the magnetic field force applied by the electromagnetic coil module 83 to drive the second filter assembly 40 to move, so as to drive the second filter 42 to switch from the second avoidance position to the second filtering position. In addition, when a pulsed current is applied to the electromagnetic coil module 83, the first magnetic lever 81 moves under the action of the magnetic field force applied by the electromagnetic coil module 83, and can also drive the first filter assembly 30 to move and drive the first filter 32 to switch from the first avoidance position to the first filtering position. At the same time, the second magnetic lever 82 moves under the action of the magnetic field force applied by the electromagnetic coil module 83, so as to drive the second filter assembly 40 to move and drive the second filter 42 to switch from the second filtering position to the second avoidance position.

[0076] That is to say, the first magnetic lever 81 and the second magnetic lever 82 of the present invention can achieve driving actions under the action of the same electromagnetic coil module 83. Only one electromagnetic coil module 83 needs to be provided in the whole structure. On the one hand, it can further reduce the volume of the dual-filter switch. On the other hand, it can ensure the synchronous movement of the first magnetic lever 81 and the second magnetic lever 82, and the switching between the first filter assembly 30 and the second filter assembly 40 is simpler and faster.

[0077] Specifically, the electromagnetic coil module 83 in this embodiment includes a first coil body 831, a second coil body 832 and a connecting block 833. The first coil body 831 and the second coil body 832 are arranged side by side at the inner bottom of the bottom shell 11 and are fixedly connected by the connecting block 833. During actual connection, the first coil body 831 and the second coil body 832 can be fixed to the connecting block 833 by means of welding, screw connection, etc.

[0078] More specifically, both the first coil body 831 and the second coil body 832 include an iron core and a winding. Among them, the iron cores of the first coil body 831 and the second coil body 832 are both strip-shaped, and the two are arranged side by side and parallel to each other. The windings on the two iron cores can be connected or independent of each other, as long as it is ensured that when a pulsed current is applied to the electromagnetic coil module 83, opposite magnetic poles can be generated at the corresponding same ends of the first coil body 831 and the second coil body 832. The first magnetic lever 81 is installed between the first ends of the first coil body 831 and the second coil body 832, and the second magnetic lever 82 is installed between the second ends of the first coil body 831 and the second coil body 832.

[0079] See Figure 8 As shown, in this application, the description is expanded with the windings of the first coil body 831 and the second coil body 832 connected. When not energized, both ends of the iron cores inside the first coil body 831 and the second coil body 832 have no polarity. The windings in the first coil body 831 and the second coil body 832 are connected. When a positive pulsed current is applied to the windings on the first coil body 831 and the second coil body 832, at this time, the yoke parts of the corresponding first ends of the iron cores in the first coil body 831 and the second coil body 832 respectively form two magnetic poles with polarities of N pole and S pole. At this time, the first magnetic lever 81 is affected by the magnetic force exerted by the iron core, and like poles repel and unlike poles attract, causing it to rotate, thereby driving the first filter assembly 30 to move. At the same time, the yoke parts of the second ends of the iron cores in the first coil body 831 and the second coil body 832 can also respectively form two magnetic poles with polarities of S pole and N pole. The second magnetic lever 82 is affected by the magnetic force exerted by the iron core, and like poles repel and unlike poles attract, causing it to rotate, thereby driving the second filter assembly 40 to move. That is to say, by applying a positive pulsed current once, the first filter assembly 30 and the second filter assembly 40 can be driven to switch simultaneously. For the next switch, only a reverse pulsed current needs to be applied to the winding. At this time, the yoke parts of the corresponding first ends of the iron cores in the first coil body 831 and the second coil body 832 respectively form two magnetic poles with polarities of S pole and N pole. At this time, the first magnetic lever 81 is affected by the magnetic force exerted by the iron core, and like poles repel and unlike poles attract, causing it to rotate, thereby driving the first filter assembly 30 to move. At the same time, the yoke parts of the second ends of the iron cores in the first coil body 831 and the second coil body 832 can also respectively form two magnetic poles with polarities of N pole and S pole. The second magnetic lever 82 is affected by the magnetic force exerted by the iron core, and like poles repel and unlike poles attract, causing it to rotate, thereby driving the second filter assembly 40 to move. That is to say, by applying a reverse pulsed current once, the first filter assembly 30 and the second filter assembly 40 can be driven to switch simultaneously.

[0080] Referring to Figures 7 to 11 as shown, in order to facilitate the installation and positioning of the first magnetic lever 81, a first positioning post 112 is provided at the inner bottom of the bottom case 11 in this embodiment. The first positioning post 112 is located in the first cavity 60, and the first positioning post 112 extends along the height direction of the bottom case 11 and is located at the first end 8301 of the electromagnetic coil module 83. The first magnetic lever 81 includes a first magnetic mounting section 811 and a first lever section 812 perpendicularly connected to the first magnetic mounting section 811. The first magnetic mounting section 811 is rotatably mounted on the first positioning post 112. One end of the first lever section 812 away from the first positioning post 112 is connected to the first light filtering assembly 30, and the first lever section 812 is located on the side of the first light filtering assembly 30 close to the bottom of the bottom case 11. Specifically, a first long slot 311 is provided on the first bearing portion 31, and a first limiting block 813 spaced from the first magnetic mounting section 811 is provided on the first lever section 812. Specifically, it can be provided at one end of the first lever section 812 away from the first magnetic mounting section 811. The first limiting block 813 is inserted into the first long slot 311. By inserting the first limiting block 813 into the first long slot 311, when the first magnetic mounting section 811 rotates around the first positioning post 112 under the action of the electromagnetic coil module 83, the first lever section 812 can drive the first limiting block 813 to move along the first long slot 311. On the one hand, it can avoid the occurrence of interference phenomena. On the other hand, it can also convert the rotation of the first lever section 812 into a linear motion of the first bearing portion 31, so as to drive the first bearing portion 31 to slide along the first sliding table 111, and finally drive the first light filter 32 to switch between the first light filtering position and the first light shielding position.

[0081] Similarly, for the convenience of installing and positioning the second magnetic lever 82, a second positioning post 113 is further provided at the inner bottom of the bottom case 11 in this embodiment. The second positioning post 113 extends from the first cavity 60 to the second cavity 70. The second positioning post 113 extends along the height direction of the bottom case 11 and is located at the second end 8302 of the electromagnetic coil module 83. The second magnetic lever 82 includes a second magnetic mounting section 821 and a second lever section 822 vertically connected to the second magnetic mounting section 821. The second magnetic mounting section 821 is rotatably mounted on the second positioning post 113, and the second magnetic mounting section 821 extends from the first cavity 60 to the second cavity 70. A relief hole 22 adapted to the second magnetic mounting section 821 is provided on the partition plate 20 to ensure that the second magnetic lever 82 can extend into the second cavity 70. After installation, the second lever section 822 is located in the second cavity 70, and one end of the second lever section 822 away from the second positioning post 113 is connected to the second light filtering assembly 40, and the second lever section 822 is located on the side of the second light filtering assembly 40 away from the bottom of the bottom case 11. Specifically, a second long hole 411 is provided on the second bearing portion 41, and a second limiting block 823 spaced from the second magnetic mounting section 821 is provided on the second lever section 822, which can be specifically arranged at one end of the second lever section 822 away from the second magnetic mounting section 821. The second limiting block 823 is inserted into the second long hole 411. By inserting the second limiting block 823 into the second long hole 411, when the second magnetic mounting section 821 rotates around the second positioning post 113 under the action of the electromagnetic coil module 83, the second lever section 822 can drive the second limiting block 823 to rotate along the second long hole 411. On the one hand, it can avoid the generation of interference phenomena, and on the other hand, it can convert the rotation of the second lever section 822 into a linear motion of the second bearing portion 41, so as to drive the second bearing portion 41 to slide along the second slide 121, and finally drive the second light filter 42 to switch between the second light filtering position and the second light shielding position.

[0082] Optionally, the first magnetic mounting section 811 and the second magnetic mounting section 821 in this embodiment are both columnar, specifically, they can be cylindrical, prismatic or other special-shaped columns. The attached Figure 7 in this application shows the case where the first magnetic mounting section 811 and the second magnetic mounting section 821 are cylindrical. Magnets are embedded in both the first magnetic mounting section 811 and the second magnetic mounting section 821, which is convenient for generating an attractive force or a repulsive force with the electromagnetic coil module 83 when the electromagnetic coil module 83 generates electromagnetic induction to drive the first magnetic mounting section 811 and the second magnetic mounting section 821 to rotate.

[0083] Optionally, the first ends of the first coil body 831 and the second coil body 832 are both arc-shaped and surround the outer periphery of the first magnetic lever 81, specifically surrounding the outer periphery of the first magnetic mounting section 811, which is convenient for applying a magnetic field force to the first magnetic mounting section 811 to drive the rotation of the first magnetic mounting section 811. The second ends of the first coil body 831 and the second coil body 832 are both arc-shaped and surround the outer periphery of the second magnetic lever 82, specifically surrounding the outer periphery of the second magnetic mounting section 821, which is convenient for applying a magnetic field force to the second magnetic mounting section 821 to drive the rotation of the second magnetic mounting section 821. The structure is compact, stable and reliable.
