Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0022] like Figure 1-4 As shown, the drone filter described in this embodiment of the present invention can be applied to, but is not limited to, DJI Mavic 3 Pro and Mavic 4 Pro drones. The drone filter includes a filter body 100 and a filter element 200; wherein the filter body 100 has a first shooting window 101 and a second shooting window 102, and a latch 103 is provided on the back of the filter body 100 for mounting and connecting the drone's lens; specifically, the drone's lens has three shooting lenses, with the first shooting window 101 facing one of the shooting lenses, and the second shooting window 102 facing the other two shooting lenses; more specifically, the three shooting lenses of the drone are a wide-angle lens, a medium telephoto lens, and a telephoto lens, with the first shooting window 101 facing the wide-angle lens, and the second shooting window 102 facing the medium telephoto lens and the telephoto lens, and the first shooting window 101 and the second shooting window 102 are arranged vertically from top to bottom.
[0023] The filter lens 200 is a single piece, mounted on the filter body 100, and simultaneously covers the first shooting window 101 and the second shooting window 102. The filter lens 200 can be an ND filter, such as ND4, ND8, ND16, ND64, ND128, ND1000, etc. It can also be an effect filter, such as an infrared cutoff filter, a graduated neutral density filter, a color filter, and special effect filters such as soft focus, wire drawing, polarizing filters, and polarized plus ND filters. Specifically, the filter body 100 has a mounting bracket on its back. The mounting groove 104 is located within the first shooting window 101 and the second shooting window 102, and the circumferential groove edge of the mounting groove 104 is located outside the first shooting window 101 and the second shooting window 102. An annular platform 105 and a partition beam 106 are formed at the bottom of the mounting groove 104. The filter lens 200 is installed in the mounting groove 104 and is connected and fixed to the annular platform 105 and the partition beam 106. The filter lens 200 can be fixed to the annular platform 105 and the partition beam 106 by ultrasonic welding or bonding (such as solid glue or liquid glue bonding).
[0024] The drone filter described in this utility model uses a single integrated filter lens mounted on the filter body, covering the shooting window for the three shooting lenses of the drone. This ensures the consistency of the filter's optical performance when switching between different lenses during shooting. In particular, the ND filter maintains consistent stop and color performance when switching between different lenses, eliminating the need for post-processing adjustments and making shooting operations more convenient.

[0025] In addition, such as Figure 2 and 3As shown, the back of the filter body 100 is provided with three locking feet 103, which are arranged in a triangle. This not only improves the assembly strength and stability of the drone filter and the drone, but also enhances the smoothness of the drone filter installation and removal, preventing the filter from scraping against the lens due to tilting during rotation and causing lens damage. Specifically, the locking foot 106 is an L-shaped section protruding from the back, used to screw into the locking slot provided on the drone. The locking foot 106 and the filter body 100 are an integrated structure. Of course, the locking foot 103 can also be other structures adapted to the structure provided on the drone, such as a buckle adapted to the fastener provided on the drone. These will not be listed here. The back of the filter body 100 is also provided with a first mounting clearance groove 107 and a second mounting clearance groove 108. The first mounting clearance groove 107 and the second mounting clearance groove 108 are respectively located at opposite corners of the back and extend to the top and left side of the mounting groove 104, and the bottom and right side of the mounting groove 104, respectively. Moreover, each of the first mounting clearance groove 107 and the second mounting clearance groove 108 is provided with one or more rotating limiting stops 109 for abutting against the outer shell of the drone lens. In this way, on the one hand, the fit between the filter and the drone is improved; on the other hand, the thickness and weight of the filter are reduced; and on the third hand, the accuracy and convenience of the filter is mounted on the drone are improved.
[0026] Of course, the filter lens 200 of this utility model can also be installed on the front of the filter body 100 and cover the first shooting window 101 and the second shooting window 102. Specifically, the front of the filter body 100 is provided with a mounting groove 104, the first shooting window 101 and the second shooting window 102 are located in the mounting groove 104, and the circumferential groove edge of the mounting groove 104 is located outside the first shooting window 101 and the second shooting window 102. An annular platform 105 and a partition beam 106 are formed at the bottom of the mounting groove 104. The filter lens 200 is installed in the mounting groove 104 and is connected and fixed to the annular platform 105 and the partition beam 106.
