Description

Technical Field

[0001] The present application relates to the technical field of lens modules, and in particular to a lens optical filter switching device and a camera. Background Art

[0002] Existing surveillance cameras generally need to keep running during the day and at night. Therefore, since they need to work during the day and at night respectively, in order to improve the quality of imaging, a filter switching device is usually installed on the surveillance camera or the camera lens, which can switch two filters of different colors in front of the CCD module. When there is sufficient sunlight during the day, the blue glass (also called phosphate glass) that professionally filters infrared rays absorbs and reflects infrared rays in natural light (more than 95% of infrared light above 700nm can be absorbed or reflected), so that the CCD can restore the true color and make the picture color more pure, beautiful and soft, satisfying the human eye vision. When there is insufficient light at night, the infrared cutoff filter automatically switches, and the full-spectrum optical glass (or infrared anti-reflection filter) starts working, so that the CCD can make full use of all light, thereby greatly improving the low-light performance.

[0003] The filter switching device in the surveillance camera is generally achieved by the meshing of gears and racks, and a small motor is used to drive the gears to rotate, driving the rack on the sliding frame to move, so as to switch the filters on the sliding frame. However, the meshing of racks and gears is prone to thread slippage during long-term use, thereby affecting the use effect. In addition, the filter switching device in the existing camera lens is generally installed in the surveillance camera by bolts. The lens of the surveillance camera is installed with the filter slice, which makes it inconvenient to disassemble the filter switching device. For this reason, the present application provides a lens optical filter switching device and a camera to solve the existing deficiencies. Utility Model Content

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] like Figure 1-Figure 8 As shown, one embodiment of the present application proposes a lens optical filter, including a frame 1, a mounting seat 2 is inserted in the frame 1, one side of the mounting seat 2 is connected to a lens socket 3, a sliding frame 4 is slidably installed inside the mounting seat 2, a filter 5 is installed in the sliding frame 4, a rocker arm 6 is rotatably installed in the mounting seat 2, a motor 7 for driving the rocker arm 6 to rotate is installed on the mounting seat 2, the output shaft of the motor 7 is connected to the rocker arm 6, a transmission part 8 is installed between the rocker arm 6 and the sliding frame 4, when the rocker arm 6 rotates, the sliding frame 4 is made to slide through the transmission part 8, a clamping component 9 acting on the mounting seat 2 is installed on the frame 1, when the mounting seat 2 is inserted into the frame 1, the sliding position of the mounting seat 2 is limited by the clamping component 9, when the mounting seat 2 is located in the frame 1, the limit on the sliding position of the mounting seat 2 is released by the clamping component 9, that is, when the motor 7 rotates, the motor 7 drives the rocker arm 6 to rotate, and the rocker arm 6 is driven by the transmission part during the rotation process. 8 enables the sliding frame 4 to move, so there is no need to drive the sliding frame 4 to move by means of gear rack transmission, thus avoiding the possibility of slipping and prolonging the service life. When the mounting seat 2 needs to be disassembled to replace the optical filter 5 inside it, it is only necessary to release the limit of the mounting seat 2 through the clamping assembly 9. During subsequent installation, it is only necessary to directly insert the mounting seat 2 into the frame frame 1, and the limit is automatically completed by the clamping assembly 9. The installation and disassembly are more convenient than the bolt installation method. Preferably, the mounting seat 2 is constructed with a limited position convex strip, and the frame frame 1 is constructed with a limited position groove, which plays a guiding and limiting role. Compared with the related art, the present application realizes the movement of the sliding frame 4 by rotating the rocker arm 6 to cooperate with the transmission part 8, thereby realizing the movement of the optical filter 5, avoiding the possibility of slipping and prolonging the service life. The disassembly and installation of the mounting seat 2 are realized by the clamping assembly 9, which is more convenient than the bolt installation method, and therefore more creative.

[0031] like Figure 3 As shown, in some embodiments, the transmission part 8 includes a column rod 801 constructed at the free end of the rocker arm 6, and a movable groove 802 is opened on the sliding frame 4. The column rod 801 is located in the movable groove 802 and slides tangent to the movable groove 802. It should be noted that sliding tangent means that the outer peripheral side of the column rod 801 is in contact with the length direction of the movable groove 802, and can move along the length direction of the movable groove 802. When the rocker arm 6 moves, it will indirectly drive the column rod 801 to move. During the movement, the column rod 801 will move along the length direction of the movable groove 802, thereby forcing the column rod 801 to pull or push the sliding frame 4 to move, so as to realize the movement of the sliding frame 4.

[0032] like Figure 2As shown, in some embodiments, the clamping assembly 9 includes two clamping parts 901 symmetrically slidably installed in the frame frame 1, a clamping groove 903 for inserting the clamping part 901 is opened on the mounting seat 2, a pull plate 902 is slidably installed on the outer side of the frame frame 1, and a linkage member 904 is installed between the pull plate 902 and the clamping part 901. When the mounting seat 2 is inserted into the frame frame 1, the two clamping parts 901 are inserted into the clamping groove 903. When the pull plate 902 moves, the two clamping parts 901 are moved away from each other through the linkage member 904. That is to say, when the mounting seat 2 is inserted into the frame frame 1, the two clamping parts 901 are inserted into the clamping groove 903. When the pull plate 902 moves, the two clamping parts 901 are moved away from each other through the linkage member 904. When the seat 2 is inserted into the frame 1, the two clamping parts 901 are away from each other during this process to ensure that the mounting seat 2 can be inserted into the frame 1. After the mounting seat 2 is inserted into the frame 1, the two clamping parts 901 are close to each other and inserted into the clamping grooves 903 respectively to complete the limitation of the mounting seat 2. When disassembly is required, it is only necessary to pull the pull plate 902. During the movement of the pull plate 902, the two clamping parts 901 are moved away from each other through the linkage part 904, so that the clamping part 901 is disengaged from the clamping groove 903 to release the limitation of the mounting seat 2.

[0033] like Figure 2 As shown, in some embodiments, the clamping portion 901 includes a wedge block 9011 horizontally slidably inserted on the frame frame 1, the inclined surface of the wedge block 9011 is located in the frame frame 1 and faces the insertion direction of the mounting seat 2, one end of the frame frame 1 is configured with a return-shaped limit plate 9013, one end of the wedge block 9011 passes through the frame frame 1 and is located outside and is connected to a connecting rod 9012, the connecting rod 9012 is connected to the linkage 904, when the mounting seat 2 is inserted into the frame frame 1, when the mounting seat 2 contacts the return-shaped limit plate 9013, it is described The installation of the mounting seat 2 is completed, and during the installation process of the mounting seat 2, one end of the mounting seat 2 contacts the inclined surface of the wedge block 9011 along the edge, so that the two wedge blocks 9011 are moved away from each other, thereby not affecting the installation of the mounting seat 2. When the installation of the mounting seat 2 is completed, the pull plate 902 is pulled, and the two connecting rods 9012 are brought close to each other through the linkage 904, so that one end of the two wedge blocks 9011 are respectively inserted into the corresponding snap-in grooves 903 to complete the installation of the mounting seat 2. Similarly, the disassembly of the mounting seat 2 can be completed.

[0034] like Figure 2 As shown, in some embodiments, the linkage 904 includes a hinged rod 9041 hinged on the pull plate 902, and the free end of the hinged rod 9041 is hinged on the connecting rod 9012. That is, when the pull plate 902 is pulled, the movement of the pull plate 902 will drive the hinged rod 9041 to move. Because one end of the hinged rod 9041 is hinged on the connecting rod 9012, when the pull plate 902 moves, the hinged rod 9041 is pulled or pushed to make the two connecting rods 9012 move closer to or farther away from each other.

[0035] like Figure 2As shown, in some embodiments, a sliding seat 10 is installed on the outer side of the frame 1, and the pull plate 902 is slidably installed on the sliding seat 10. A magnetic block 11 is installed between the sliding seat 10 and the pull plate 902. The two magnetic blocks 11 are attracted to each other by opposite charges. When the pull plate 902 is pulled, the pull plate 902 and the two magnetic blocks 11 on the sliding seat 10 are adsorbed together. At this time, the wedge block 9011 is disengaged from the snap-in groove 903, preventing the pull plate 902 from accidentally sliding and causing the wedge block 9011 to move into the snap-in groove 903.

[0036] like Figure 3 As shown, in some embodiments, a guide rod 12 is horizontally installed on the frame 1, and a return spring 20 is mounted on the guide rod 12. The connecting rod 9012 is slidably mounted on the guide rod 12, and one end of the return spring 20 abuts against the guide rod 12, and the other end of the return spring 20 abuts against the connecting rod 9012. The return spring 20 makes the wedge block 9011 abut against the clamping groove 903, so that when the frame 1 is vibrated or accidentally moved, the elastic reset of the return spring 20 makes it difficult for the wedge block 9011 to be separated from the clamping groove 903, thereby playing a protective role.

[0037] like Figure 5-Figure 8 As shown, the present application also proposes a camera using the above-mentioned lens optical filter switching device, including the above-mentioned lens optical filter switching device, and also including a camera housing 13, a partition groove 14 is opened on one side of the camera housing 13, one corner of the frame 1 is rotatably installed in the partition groove 14 to cover the partition groove 14, one end of the camera housing 13 is opened with a mounting groove 15, a docking plate 17 is slidably inserted in the mounting groove 15, a lens module 16 is installed on the docking plate 17, one end of the lens module 16 is inserted in the lens plug sleeve 3, and a locking component 18 for releasing or fixing the docking plate 17 in the mounting groove 15 is installed on the camera housing 13. The design of the partition groove 14 allows the frame 1 to rotate into the partition groove 14. When the mounting seat 2 is removed, the frame 1 just covers the partition groove 14, thereby preventing dust from entering the mounting seat 2 and covering the filter 5 with dust. When the mounting seat 2 needs to be disassembled, it is only necessary to remove the docking plate 17 from the mounting groove 15 through the locking assembly 18, so that the lens module 16 is disengaged from the lens sleeve 3, and the limit on the rotation angle of the frame 1 is released. Then, the frame 1 is rotated to expose the frame 1 to the outside, thereby facilitating the removal of the mounting seat 2 from the frame 1. Compared with the existing ones, when the filter 5 on the mounting seat 2 needs to be replaced, it is only necessary to slide the docking plate 17 out of the mounting groove 15 through the locking assembly 18, and then the frame 1 is rotated to expose the mounting seat 2 to the outside, thereby facilitating the removal of the mounting seat 2 from the frame 1.

[0038] like Figure 7 and Figure 8As shown, in some embodiments, the locking assembly 18 includes a receiving groove 1801 provided on the docking plate 17, a positioning plate 1807 is vertically rotatably installed in the receiving groove 1801, a driving plate 1802 is slidably installed on the receiving groove 1801, a transmission groove 1808 is provided on the driving plate 1802, a transmission rod 1803 is configured on one side of the positioning plate 1807, a movable column 1804 is configured at one end of the transmission rod 1803, the movable column 1804 slides tangentially in the transmission groove 1808, and a resisting spring piece 1805 is installed between the driving plate 1802 and the receiving groove 1801 to form a fixed position. The positioning plate 1807 is partially located outside the receiving groove 1801, and a positioning bevel groove 1806 for the positioning plate 1807 to be clamped is provided on the camera housing 13. A driving assembly 19 acting on the positioning plate 1807 is installed on the camera housing 13. When the positioning plate 1807 is located in the positioning bevel groove 1806, the driving assembly 19 is used to move the positioning plate 1807 into the receiving groove 1801. That is to say, when the docking plate 17 needs to be inserted into the installation groove 15, the positioning plate 1807 can be rotated at this time so that the positioning plate 1807 is rotated into the receiving groove 1801, and the positioning plate 1807 is rotated into the receiving groove 1801. 07 will make the transmission rod 1803 move during the rotation process, and because the movable column 1804 on the transmission rod 1803 slides tangentially with the transmission groove 1808 on the driving plate 1802, the positioning plate 1807 will force the driving plate 1802 to move during the rotation, so that the driving plate 1802 squeezes the resisting spring piece 1805. At this time, the resisting spring piece 1805 is in a compressed state and is in a Z shape. Then the docking plate 17 is inserted into the installation groove 15. At this time, the positioning plate 1807 is pressed against the elastic resistance of the resisting spring piece 1805. The docking plate 17 contacts the groove wall of the installation groove 15, and continues to move until the positioning plate 1807 moves into the positioning inclined groove 1806. At this time, the resistance spring 1805 causes the driving plate 1802 to move due to its own elastic deformation characteristics, thereby forcing the positioning plate 1807 to rotate outward from the receiving groove 1801, so that the positioning plate 1807 contacts the positioning inclined groove 1806 to complete the rapid installation of the docking plate 17. When the docking plate 17 needs to be disassembled, it is only necessary to move the positioning plate 1807 into the receiving groove 1801 through the driving assembly 19, and then the docking plate 17 can be pulled out.

[0039] like Figure 7 and Figure 8As shown, in some embodiments, the driving assembly 19 includes a sliding groove 1901 horizontally opened on the camera housing 13, one end of the sliding groove 1901 is connected to the positioning inclined groove 1806 and a push plate 1903 is slidably installed inside, and the top of the push plate 1903 is connected to a driving rod 1904 located outside, and one end of the sliding groove 1901 is opened with a mounting hole 1905, and a return spring 1902 is installed in the mounting hole 1905, and the free end of the return spring 1902 is against the push plate 1903. That is to say, when the positioning plate 1807 is located in the positioning inclined groove 1806, it is necessary to move the positioning plate 1807 to the position of the camera housing 13. When disassembling the connecting plate 17, first move the driving rod 1904. During the movement, the driving rod 1904 will drive the pushing plate 1903 to move in the direction of the positioning bevel groove 1806, so that the pushing plate 1903 contacts the positioning plate 1807. At this time, the return spring 1902 is in a stretched state, and then continue to move the pushing plate 1903 so that the bottom of the pushing plate 1903 is located above the positioning plate 1807, so that the positioning plate 1807 is horizontal. At this time, the positioning plate 1807 has been separated from the positioning bevel groove 1806 and is located in the accommodating groove 1801, thereby releasing the limit on the sliding position of the connecting plate 17.

[0040] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
