Specifically, the following multiple embodiments may be used individually as a technical solution or combined into one technical solution.

[0032] See also Figure 1 and Figure 2 The embodiment of the present application provides a filter component 100, which includes a filter assembly 10 and a filter holder 20. The filter assembly 10 is mounted on the filter holder 20, and the filter holder 20 can be mounted at the front end of the lens of the shooting device.

[0033] See also Figure 3 The filter assembly 10 may include a filter 11 and a filter frame 12. The filter 11 is installed in the filter frame 12. The filter frame 12 is installed on the filter bracket 20. The filter frame 12 can protect the filter 11 and facilitate the disassembly and assembly of the filter 11 to prevent the filter 11 from being scratched during the installation of the filter assembly 10. The filter frame 12 can be made of high-strength materials, such as high-strength nylon, engineering plastics, zinc alloy, aluminum alloy and other materials. Figure 3 In the embodiment shown, the filter frame 12 and the filter are both rectangular. In other embodiments, the filter frame 12 may be square, and the filter 11 may be circular, triangular, square, etc.; or, the filter frame 12 may be pentagonal, hexagonal, etc., which are not listed here one by one.

[0034] See also Figure 4 The filter holder 20 provided in the embodiment of the present application includes a holder body 21 and a locking assembly 22. The holder body 21 can be used to support and accommodate the filter assembly 10. The locking assembly 22 can be installed on the holder body 21. The locking assembly 22 is used to lock the filter assembly 10 when the filter assembly 10 is installed on the holder body 21 to prevent the filter assembly 10 from falling off. When the filter assembly 10 needs to be removed from the holder body 21, the locking assembly 22 can be operated to release the filter assembly 10, and then the filter assembly 10 can be removed from the holder body 21. In this way, the disassembly and assembly of the filter assembly 10 is relatively convenient, and the process of replacing the filter is also more convenient.

[0035] In the related art, a horizontal guide rail is provided on the filter holder to lock the filter installed in the filter frame after insertion. Since the filter is relatively long, it is easy to get stuck during the disassembly and assembly process, which affects the user experience and work efficiency.

[0036] The support body 21 is provided with a receiving cavity 211, and the receiving cavity 211 can be used to receive the filter assembly 10. In the first direction X, the receiving cavity 211 includes a first side 2111 and a second side 2112 opposite to each other. The receiving cavity 211 is provided with a first limiting portion 2113 on the first side 2111, and the first limiting portion 2113 can be used to limit the first end 121 of the filter assembly 10. The receiving cavity 211 is provided with an opening 2114 on the second side 2112. The locking assembly 22 is movably connected to a side of the support body 21 close to the opening 2114, and the locking assembly 22 has a locking position and a releasing position, and the locking assembly 22 is provided with a second limiting portion 221. Figure 1 As shown, when the locking assembly 22 is in the locking position, the second limiting portion 221 is used to limit the second end 122 of the filter assembly 10; Figure 8 As shown, when the locking assembly 22 is in the release position, the second limiting portion 221 is used to release the second end 122 of the filter assembly 10. The first end 121 and the second end 122 of the filter assembly 10 are two ends of the filter assembly 10 in the first direction X.

[0037] The filter holder 20 and the filter component 100 provided in the embodiment of the present application are provided with a receiving cavity 211 in the holder body 21, and a first limiting portion 2113 is provided on one side of the receiving cavity 211, and an opening 2114 is provided on the other side. The locking component 22 is movably connected to a side of the holder body 21 close to the opening 2114, and the locking component 22 can move relative to the holder body 21, and can be switched between a locked position and a released position. The locking component 22 is provided with a second limiting portion 221. When the locking component 22 is in the locked position, the second limiting portion 221 The second end 122 of the filter assembly 10 can be limited by the first limiting portion 2113, and the first end 121 of the filter assembly 10 can be limited by the first limiting portion 2113, so as to limit the filter assembly 10 on the filter bracket 20. When in the released position, the second limiting portion 221 of the locking assembly 22 is separated from the second end 122 of the filter assembly 10, so that the filter assembly 10 can be removed from the filter bracket 20. Therefore, the filter assembly 10 is more convenient to be disassembled and assembled on the filter bracket 20, thereby improving the convenience and reliability of filter installation, and the filter assembly 10 is more smooth to be disassembled and assembled.

[0038] Taking the first direction X as the left-right direction as an example, the first side 2111 of the receiving cavity 211 is the left side, and the second side 2112 is the right side. The first end 121 of the filter assembly 10 is the left end, and the second end 122 is the right end.

[0039] See also Figures 1 to 3 Specifically, the two ends of the filter frame 12 are respectively limited at the first limit portion 2113 and the second limit portion 221. The second end 122 of the filter frame 12 may be provided with a hand-held portion 123, so as to facilitate hand-holding when disassembling and assembling the filter assembly 10. The hand-held portion 123 may include lugs, stripes, convex points, etc., which are not listed here one by one. Figure 3 In the illustrated embodiment, the hand-held portion 123 includes a lug formed by protruding from the edge of the filter frame 12 , and the lug is provided with concave-convex stripes to increase the friction between the hand and the filter frame 12 during taking and placing.

[0040] See also Figure 4 and Figure 5 The outline of the bracket body 21 can be roughly rectangular, and the bracket body 21 can be made of high-strength materials, such as high-strength nylon, engineering plastics, zinc alloy, aluminum alloy and other materials.

[0041] Please continue reading Figure 4 and Figure 5 The bracket body 21 may include a back wall 212, a top wall 213, a side wall 214 and a bottom wall 215. The top wall 213, the side wall 214 and the bottom wall 215 are all connected to the back wall 212. The two ends of the side wall 214 are respectively connected to the top wall 213 and the bottom wall 215. The back wall 212, the top wall 213, the side wall 214 and the bottom wall 215 enclose a receiving cavity 211, and the side wall 214 is provided with a first limiting portion 2113.

[0042] The back wall 212 can provide back support for the filter assembly 10, the bottom wall 215 can also provide support for the filter assembly 10, and can limit the filter assembly 10 in the negative direction of the second direction Y, the top wall 213 can limit the filter assembly 10 in the positive direction of the second direction Y, so that the filter assembly 10 will not deviate in the second direction Y, and the side wall 214 can be provided with a first limiting portion 2113 to limit the first end 121 of the filter assembly 10. The first limiting portion 2113 can be located in the middle area of ​​the side wall 214 to better limit the first end 121 of the filter assembly 10. In other embodiments, the first limiting portion 2113 can also be located in the upper and lower areas of the side wall 214, or the first limiting portion 2113 can be located on the entire inner side of the side wall 214. The second direction Y can be perpendicular to the first direction X, for example, the second direction Y can be a vertical direction.

[0043] Please continue reading Figure 4 and Figure 5In one embodiment, the first limiting portion 2113 may include a first limiting groove, whereby the first end 121 of the filter assembly 10 is easier to take and place, and also can achieve a better limiting effect. The first limiting groove may extend along the second direction Y, so that the first limiting portion 2113 can limit a certain area of ​​the first end 121 of the filter assembly 10 to ensure the limiting accuracy. Among them, the side wall 214 may be recessed to form the first limiting groove, or a convex rib may be convexly provided on the side wall 214, and the convex rib and the bottom wall 215 may form the first limiting groove, or two convex ribs may be convexly provided on the side wall 214 to form two oppositely arranged convex ribs, and the two convex ribs are spaced apart to form the first limiting groove. In other embodiments, the first limiting portion 2113 may also include limiting buckles, limiting bosses, limiting columns, etc., which are not listed one by one here, and are not specifically limited.

[0044] The back wall 212 of the support body 21 may be provided with a light hole 2121 penetrating along the third direction Z, so that the light passing through the filter can pass through the support body. The diameter of the light hole 2121 may be the same or nearly the same as the width of the receiving cavity 211 or the width of the filter, so that most of the light beams passing through the filter can pass through the support body. The third direction Z is perpendicular to the first direction X and the second direction Y, that is, the first direction X, the second direction Y and the third direction Z are perpendicular to each other, and the third direction Z may be a front-to-back direction.

[0045] See also Figure 6 The side of the back wall 212 away from the receiving cavity 211 is provided with a clamping structure 2122, and the clamping structure 2122 is used to clamp the filter holder 20 to a shooting device (such as a camera, a video camera, etc.) or other shooting equipment. The clamping structure 2122 may include a buckle, a clamping plate, etc. Figure 6 As shown, the snap-fit ​​structure 2122 includes four snaps, two of which are arranged at the upper end and two of which are arranged at the lower end. In this way, the filter holder 20 is more stable when snapped onto other structures and is convenient for assembly and disassembly.

[0046] See also Figure 1 and Figure 4 The lock assembly 22 can be movably connected to the bracket body 21 by rotating, sliding, etc., so that the lock assembly 22 can move relative to the bracket body 21 and has a locking position and a release position. When the lock assembly 22 is in the locking position, the lock assembly 22 can lock the filter frame 12, and the filter assembly 10 cannot be removed at this time; when the lock assembly 22 is in the release position, the lock assembly 22 can release the filter frame 12, that is, the second limit portion 221 of the lock assembly 22 is separated from the filter frame 12, and the filter assembly 10 can be removed at this time; thus, through the cooperation between the lock assembly 22 and the bracket body 21, the filter assembly 10 is convenient to disassemble and assemble.

[0047] The lock assembly 22 may include a lock, such as a long strip lock extending along the second direction Y, and the long strip lock may be movably connected to the bracket body 21. The lock assembly 22 may also include multiple locks, such as two, three, four or more, and the multiple locks may be rotatably connected to the bracket body 21. The second limiting portion 221 may be a limiting groove, a limiting buckle, a limiting pin, etc.

[0048] See also Figure 1 , Figure 4 and Figure 5 The lock assembly 22 may include a first lock 222, a second lock 223 and a connector 224. The first lock 222 and the second lock 223 are both movably connected to the bracket body and spaced apart along the second direction Y. Both ends of the connector 224 are respectively connected to the first lock 222 and the second lock 223. The first lock 222 and the second lock 223 are both provided with a second limiting portion 221. The second direction Y is perpendicular to the first direction X. The connector 224 is used to make the first lock 222 and the second lock 223 work in a linkage manner.

[0049] The first lock buckle 222 and the second lock buckle 223 are arranged at intervals in the second direction Y, so that the first lock buckle 222 and the second lock buckle 223 can respectively lock different positions of the bracket body 21, thereby improving the stability of the limit. The first lock buckle 222 and the second lock buckle 223 are connected by the connecting member 224, so that the first lock buckle 222 and the second lock buckle 223 can be linked, for example, one of the first lock buckle 222 and the second lock buckle 223 can be operated to make the other of the first lock buckle 222 and the second lock buckle 223 move synchronously; or the connecting member 224 can be operated to make the first lock buckle 222 and the second lock buckle 223 move simultaneously; thereby avoiding the need to operate the first lock buckle 222 and the second lock buckle 223 separately, thereby improving the efficiency of disassembly and assembly.

[0050] The second limiting portion 221 may include a limiting groove, a limiting block, a limiting pin, a limiting protrusion, etc., which are not specifically limited here. Figure 4 and Figure 5 In the illustrated embodiment, the second limiting portion 221 includes a second limiting groove, which may be formed by two convex walls spaced apart from each other, so as to limit the filter frame 12 on both sides of the third direction Z.

[0051] See also Figure 4 and Figure 6, the thickness of the first lock buckle 222, the second lock buckle 223 and the connecting member 224 are all greater than the thickness of the bracket body, and the first lock buckle 222, the second lock buckle 223, the connecting member 224 and the bracket body 21 enclose an operation space 225. In the third direction Z, the first lock buckle 222, the second lock buckle 223 and the connecting member 224 may all protrude compared to the bracket body 21, and both sides in the third direction Z have an operation space 225, so that the user can operate the connecting member 224, the first lock buckle 222 or the second lock buckle 223 in the operation space 225, which is convenient for user operation and improves the user experience. In the first direction X, there may be a gap between the connecting member 224 and the bracket body 21 to facilitate the operation of the connecting member 224 and have a larger activity space.

[0052] See also Figure 5 In the second direction Y, the bracket body 21 includes a first clamping portion 216 and a second clamping portion 217 that are spaced apart, the first lock buckle 222 includes a third clamping portion 2221, and the second lock buckle 223 includes a fourth clamping portion 2231. When the lock buckle assembly 22 is in the locked position, the first clamping portion 216 is clamped with the third clamping portion 2221, and the second clamping portion 217 is clamped with the fourth clamping portion 2231. By engaging the first lock buckle 222 and the second lock buckle 223 with the bracket main body 21, the first lock buckle 222 and the second lock buckle 223 limit the filter assembly 10, and by releasing the engagement of the first lock buckle 222 and the second lock buckle 223 with the bracket main body 21, the first lock buckle 222 and the second lock buckle 223 release the filter assembly 10. Compared with the method of engaging the first lock buckle 222 and the second lock buckle 223 with the filter assembly 10, the present embodiment does not need to provide the filter assembly 10 with a locking structure 2122, the filter bracket 20 has a wider applicability, and the requirements for the filter assembly 10 are lower. The specific structures of the first locking portion 216 and the second locking portion 217 can be the same or different, and the third locking portion 2221 and the fourth locking portion 2231 can be the same or different. The first locking portion 216 and the third locking portion 2221 are structurally compatible, and the second locking portion 217 and the fourth locking portion 2231 are structurally compatible. For example, the first clamping portion 216 is a hook, and the third clamping portion 2221 is a slot; for another example, the first clamping portion 216 and the second clamping portion 217 are both hooks, and the hooks are in opposite directions; for another example, the first clamping portion 216 is a buckle, and the third clamping portion 2221 is a protrusion. The second clamping portion 217 and the fourth clamping portion 2231 are similar to the first clamping portion 216 and the third clamping portion 2221, and are not described in detail here.

[0053] See also Figure 5 and Figure 7, the first clamping part 216 may include a first protrusion, and the third clamping part 2221 may include a first groove. When the locking assembly 22 is in the locking position, the first protrusion is inserted into the first groove to realize the clamping of the first clamping part 216 and the third clamping part 2221; when the locking assembly 22 is in the releasing position, the first protrusion is separated from the first groove to realize the release of the clamping of the first clamping part 216 and the third clamping part 2221. Alternatively, the first clamping part 216 may include a first protrusion, and the third clamping part 2221 may include a first protrusion. When the locking assembly 22 is in the locking position, the first protrusion is abutted against the first protrusion to realize the clamping of the first clamping part 216 and the third clamping part 2221; when the locking assembly 22 is in the releasing position, the first protrusion is separated from the first protrusion to realize the release of the clamping of the first clamping part 216 and the third clamping part 2221. In other embodiments, the first clamping portion 216 may include a first groove, and the second clamping portion 217 may include a first protrusion. When the locking assembly 22 is in the locking position, the first protrusion is clamped with the first groove; when the locking assembly 22 is in the releasing position, the first protrusion is released from the clamping with the first groove.

[0054] The second clamping portion 217 may include a second protrusion, and the fourth clamping portion 2231 may include a second groove or a second protrusion, and the second protrusion is clamped with the second groove or the second protrusion. The second protrusion is similar to the first protrusion, the second groove is similar to the first groove, and the second protrusion is similar to the first protrusion, which will not be described in detail here.

[0055] See also Figure 5 and Figure 7 The support body 21 further includes a first receiving opening 218 and a second receiving opening 219 spaced apart along the second direction Y. When the lock assembly 22 is in the locked position, the first lock 222 is at least partially located in the first receiving opening 218, and the second lock 223 is at least partially located in the second receiving opening 219. Thus, the structure of the filter support 20 is relatively compact. Meanwhile, the first lock 222 and the second lock 223 can further limit the second end 122 of the filter assembly 10, so that the filter assembly 10 has better stability. The first clamping portion 216 can be located at one side of the first receiving opening 218 and can be a part of the structure forming the first receiving opening 218. The second clamping portion 217 can be located at one side of the second receiving opening 219 and can be a part of the structure forming the second receiving opening 219. Thus, the clamping of the first lock 222 and the second lock 223 is tighter.

[0056] See also Figure 4 , Figure 5 and Figure 7, the first lock buckle 222 and the second lock buckle 223 may both include a third limiting portion 226. When the lock buckle assembly 22 is in the locked position, the bracket body 21 partially extends into the third limiting portion 226. Therefore, the third limiting portion 226 can realize the positioning of the first lock buckle 222 and the second lock buckle 223 while realizing the limitation. At the same time, the locking relationship between the first lock buckle 222 and the second lock buckle 223 is more stable. Among them, the third limiting portion 226 and the second limiting portion 221 can be arranged side by side in the third direction Z. The third limiting portion 226 can be a limiting groove extending along the second direction Y like the second limiting portion 221, or it can be a limiting buckle, a limiting block, a limiting pin, etc., and no specific restrictions are made here. Figure 4 and Figure 5 In the corresponding embodiment, the third limiting portion 226 is a third limiting groove formed by two convex walls. The second limiting groove and the third limiting groove may share a convex wall. Figure 4 and Figure 5 As shown, the second limiting groove and the third limiting groove are the same limiting groove, that is, the bracket body 21 and the second end 122 of the filter frame 12 are both limited in the same limiting groove, and the bracket body 21 can limit the filter frame 12 together with the first lock buckle 222 and the second lock buckle 223.

[0057] See also Figure 4 and Figure 5 The first lock buckle 222 and the second lock buckle 223 are both rotatably connected to the bracket body 21, and the first rotation axis of the first lock buckle 222 and the second rotation axis of the second lock buckle 223 are both perpendicular to the first direction X and the second direction Y. The first lock buckle 222 and the second lock buckle 223 are both rotatably connected to the bracket body 21, so that the first lock buckle 222 and the second lock buckle 223 can be rotated relative to the bracket body 21, and then the positions of the first lock buckle 222 and the second lock buckle 223 relative to the bracket body 21 are switched, so that the first lock buckle 222 and the second lock buckle 223 can be switched between the locking position and the releasing position, which is more convenient to operate.

[0058] Specifically, please combine Figure 7 A first axial hole 2222 is defined on the first lock buckle 222, a second axial hole 2232 is defined on the second lock buckle 223, a third axial hole 21a and a fourth axial hole 21b are defined on the bracket body 21, the filter bracket 20 may further include a first shaft rod 23 and a second shaft rod 24, the first shaft rod 23 is passed through the first axial hole 2222 and the third axial hole 21a, the second shaft rod 24 is passed through the second axial hole 2232 and the fourth axial hole 21b, the first lock buckle 222 can rotate relative to the bracket body 21 around the first shaft rod 23, and the second lock buckle 223 can rotate relative to the bracket body 21 around the second shaft rod 24.

[0059] See also Figure 4 and Figure 5The first lock buckle 222 and the second lock buckle 223 are rotatably connected to the two ends of the connecting member 224, respectively, and the third rotation axis of the first lock buckle 222 and the fourth rotation axis of the second lock buckle 223 are perpendicular to the first direction X and the second direction Y. Therefore, the first lock buckle 222 and the second lock buckle 223 can be linked through the connecting member 224, and the operation of the lock buckle is more convenient and flexible. The first lock buckle 222 and the second lock buckle 223 can be driven to rotate by operating the connecting rod, so that the first lock buckle 222 and the second lock buckle 223 are engaged or disengaged with the filter holder 20.

[0060] Specifically, please combine Figure 7 A fifth axial hole 2223 is provided on the first lock buckle 222, a sixth axial hole 2233 is provided on the second lock buckle 223, and a seventh axial hole 2241 and an eighth axial hole 2242 are provided at both ends of the bracket body 21 in the second direction Y. The filter bracket 20 may also include a third shaft rod 25 and a fourth shaft rod 26. The third shaft rod 25 is penetrated through the fifth axial hole 2223 and the seventh axial hole 2241, and the fourth shaft rod 26 is penetrated through the sixth axial hole 2233 and the eighth axial hole 2242. The first lock buckle 222 can rotate relative to the connecting member 224 around the third shaft rod 25, and the second lock buckle 223 can rotate relative to the connecting member 224 around the third shaft rod 25.

[0061] See also Figure 4 , Figure 5 and Figure 8 The centers of the first shaft 23, the second shaft 24, the third shaft 25 and the fourth shaft 26 are connected in sequence to form a deformable parallelogram, and the position can be changed by pulling one of the sides, thereby realizing flexible change of the position of the first lock buckle 222 and the second lock buckle 223.

[0062] See also Figure 4 , Figure 5 and Figure 8 The connecting member 224 includes a connecting rod, which connects the first lock buckle 222 and the second lock buckle 223, and can transmit force and movement to the first lock buckle 222 and the second lock buckle 223. When one of the lock buckles moves, the other lock buckle moves synchronously, thereby improving the convenience of operation. Among them, the first lock buckle 222 and the second lock buckle 223 can be made to move synchronously by applying an external force (such as a push or a pull) to the connecting rod, making it more convenient to remove and install the filter. In other embodiments, the connecting member 224 may also include multiple connecting rods or a plate-like structure.

[0063] See also Figure 4 , Figure 5 and Figure 7, the connecting member 224 includes a body 2245, a first lug 2243 and a second lug 2244, the first lug 2243 and the second lug 2244 are respectively connected to the two ends of the body 2245 in the second direction Y, the first lug 2243 is rotatably connected to the first lock buckle 222, and the second lug 2244 is rotatably connected to the second lock buckle 223. As a result, the movable connection between the connecting member 224 and the first lock buckle 222 and the second lock buckle 223 is better. In the third direction Z, the thickness of the first lug 2243 and the second lug 2244 can be less than that of the body 2245, so that the first lug 2243 and the second lug 2244 can be respectively clamped in the movable grooves of the first lock buckle 222 and the second lock buckle 223. The first lug 2243 can form the seventh shaft hole 2241, and the second lug 2244 can form the eighth shaft hole 2242. When the first lock buckle 222 is rotatably connected to the first lug 2243, a certain gap may be provided between the first lock buckle 222 and the body 2245 to facilitate the rotation of the first lock buckle 222. When the second lock buckle 223 is rotatably connected to the second lug 2244, a certain gap may be provided between the second lock buckle 223 and the body 2245 to facilitate the rotation of the second lock buckle 223.

[0064] See also Figure 4 , Figure 5 and Figure 7 The cross section of the connecting member 224 parallel to the first direction X is trapezoidal, and the short side of the trapezoid is closer to the bracket body 21. Therefore, it is easier to hold the connecting member 224, and then it is easier to pull the connecting member 224 when the filter assembly 10 needs to be released, and it is also easier to apply a thrust to the connecting member 224 when the filter assembly 10 needs to be locked.

[0065] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments, the use method and principle of the filter holder 20 of the present application are as follows:

[0066] First, align the first end 121 of the filter assembly 10 with the first limiting portion 2113 (e.g., the first limiting groove) of the bracket body and insert it obliquely, then push the filter assembly 10 forward until the rear surface of the filter assembly 10 fits the bracket body, and then push the connecting member 224 to the left (i.e., the negative direction of the first direction X). The first locking buckle 222 and the second locking buckle 223 are driven by the connecting member 224 to rotate counterclockwise around the first rotating shaft and the second rotating shaft respectively, and the second end 122 of the filter assembly 10 begins to fall into the second limiting groove on the locking buckle. The connecting member 224 is pushed leftwardly into the positioning portion 221 (for example, the second limiting groove) until the first clamping portion 216 on the bracket body 21 is engaged with the third clamping portion 2221 on the first locking buckle 222, and the second clamping portion 217 on the bracket body 21 is engaged with the fourth clamping portion 2231 on the second locking buckle 223. Then, the connecting member 224 cannot be pushed further, and the first locking buckle 222 and the second locking buckle 223 are both in the locked position. At this time, the filter assembly 10 is reliably fixed in the filter bracket 20.

[0067] Please combine Figure 8 When the filter assembly 10 needs to be taken out, the connecting piece 224 is pulled out to the right side (i.e., the positive direction of the first direction X). At this time, the first locking buckle 222 and the second locking buckle 223 are driven by the connecting piece 224 to rotate clockwise around the first rotating shaft and the second rotating shaft respectively, so that the first clamping portion 216 on the bracket body 21 and the third clamping portion 2221 on the first locking buckle 222 are gradually uncoupled, and the second clamping portion 217 on the bracket body 21 and the fourth clamping portion 2231 on the second locking buckle 223 are gradually uncoupled, and the filter frame 12 gradually disengages from the second limiting portion 221 on the first locking buckle 222 and the second locking buckle 223 until it is completely disengaged, and the filter assembly 10 can be smoothly taken out of the bracket body.
