Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-5, an embodiment of the present invention is a lens filter switcher, including a housing 1, a driving module 2, and a sliding frame 3, wherein a light hole 4 is formed in the middle of the housing 1, a first filter 5 and a second filter 6 are mounted on the sliding frame 3, the driving module 2 is in driving connection with the sliding frame 3, and the sliding frame 3 can horizontally slide to switch the first filter 5 or the second filter 6 to correspond to the light hole 4;

the driving module 2 is electrically connected to the main circuit board through a pin terminal 7 by using a connecting wire 8. The sliding frame is driven by the driving module to slide, so that the first optical filter and the second optical filter on the sliding frame are displaced, and the optical filters transmitting the filtering light holes, such as the daytime optical filter of the first optical filter 5 or the nighttime infrared optical filter of the second optical filter 6, are converted.

The driving module 2 comprises a fixed frame 201, a coil 202, a swing arm 203 and a magnet 204, wherein the swing arm 203 is hinged to the fixed frame 201, one end of the swing arm 203 is in driving connection with the sliding frame 201, a magnetic part 205 is further embedded and mounted on the swing arm 203, the coil 202 is mounted on one side of the fixed frame 201, and the coil 202 is electrically connected with a pin terminal 7; when the coil is electrified, a magnetic field is generated to adsorb the magnetic part to drive the swing arm to rotate, the sliding frame 3 slides to one side, and the position corresponding to the light hole 4 is switched from the first light filter 5 to the second light filter 6. The sliding of the sliding frame is realized by utilizing the principle of magnetic attraction, the space is fully utilized, and the product volume is reduced.
