And as used in this application, "connection" and "coupling", unless otherwise specified, both include direct and indirect connection (coupling).

[0058] In order to solve the technical problems of difficult positioning and inconvenient assembly and disassembly in the prior art solution where a sunshade kit uses structures such as screws and bolts to achieve detachable connection, some embodiments of the present application provide a sunshade kit. This sunshade kit can effectively improve or solve the technical problem of inconvenient assembly and disassembly, and has the technical effects of convenient assembly and convenient use.

[0059] Please refer to Figure 1 and Figure 2 , in some embodiments, the sunshade kit 100 includes a sunshade body 10, a mounting body 20, a first magnetic member 11, and a second magnetic member 21. Please refer to Figure 1 and Figure 2 , in some embodiments, the sunshade body 10 has a first connection structure 12 and a first light passage 13 that penetrates in the first direction; the mounting body 20 is used to mount and fix a lens, the mounting body 20 has a second connection structure 22 and a second light passage 23 that penetrates in the first direction; the first magnetic member 11 is disposed on the sunshade body 10; the second magnetic member 21 is disposed on the mounting body 20. Wherein, the first magnetic member 11 and the second magnetic member 21 attract each other to pre-position and pre-connect the sunshade body 10 and the mounting body 20, and the first connection structure 12 and the second connection structure 22 form a detachable fixation, so that the first light passage 13, the second light passage 23, and the lens are opposite and connected in the first direction. The first direction is Figure 1 the X direction in

[0060] In the above embodiments, the first magnetic member 11 on the light-shielding hood body 10 is adapted to the second magnetic member 21 of the mounting body 20. Under the action of the magnetic attraction of opposite sexes, pre-positioning and pre-connection can be quickly achieved. Furthermore, without the impact of external force, the hands of the user can be liberated and other operations can be performed, such as finely adjusting the relative positions of the mounting body 20 and the light-shielding hood body 10, such as assembling and connecting the first connection structure 12 and the second connection structure 22. To a certain extent, the hand-held operation can be omitted and the assembly difficulty can be reduced. Then, by aligning the first connection structure 12 and the second connection structure 22 and detachably connecting and fixing them, the assembly of the light-shielding hood kit 100 can be completed. The mounting body 20 is used to be connected and fixed to the lens, and the light-shielding hood kit 100 is integrally mounted on the lens so that the first light passage 13 and the second light passage 23 can be aligned with the lens. Compared with the prior art, the present application realizes a fast assembly and disassembly solution of pre-positioning, pre-connection and then detachable fixing, and has the technical effects of convenient assembly and convenient use.

[0061] In some embodiments, in order to improve the alignment accuracy of the first magnetic member 11 and the second magnetic member 21, the light-shielding hood body 10 and the mounting body 20 can form a positioning fit, thereby playing a guiding role. For example, in some embodiments, pin holes can be formed on both the light-shielding hood body 10 and the mounting body 20, and higher-precision pre-positioning can be achieved through the pin holes and detachable positioning pins. In still other embodiments, a counterbore matching the end of the mounting body 20 can be formed on the light-shielding hood body 10, and the end of the mounting body 20 is directly in positioning fit with the counterbore. Similarly, in some embodiments, a counterbore can also be formed on the end of the mounting body 20 close to the light-shielding hood body 10, and the end portion of the light-shielding hood body 10 is partially embedded in the counterbore to achieve pre-positioning.

[0062] In some embodiments, in order to improve the alignment accuracy of the first magnetic member 11 and the second magnetic member 21 and at the same time ensure the structural strength of the light-shielding hood body 10 and the mounting body 20, the light-shielding hood body 10 further has at least one first boss 17, and the mounting body 20 further has at least one first groove 28, and the first boss 17 corresponds to and is adapted to the first groove 28; and / or, the light-shielding hood body 10 further has at least one second groove 18, and the mounting body 20 further has at least one second boss 27, and the second groove 18 corresponds to and is adapted to the second boss 27. In other words, only the first boss 17 or only the second groove 18 can be provided on the light-shielding hood body 10, or alternatively, both the first boss 17 and the second groove 18 can be provided. For example, in some embodiments, please refer to Figure 4 , four first bosses 17 are provided on the light-shielding hood body 10, and four first grooves 28 are correspondingly provided on the mounting body 20; in other embodiments, please refer to Figure 2, two first bosses 17 and two second grooves 18 are provided on the light-shielding hood body 10, and two first grooves 28 and two second bosses 27 are correspondingly provided on the mounting body 20.

[0063] In different embodiments, taking the setting of the light-shielding hood body 10 as an example, the total number of the first bosses 17 and / or the second grooves 18 can be adjusted adaptively as long as it can meet the pre-positioning of the mounting body 20 and the light-shielding hood body 10. This pre-positioning can be a precise pre-positioning scheme that directly aligns the first connection structure 12 and the second connection structure 22, or a scheme that locates the basic positions of the mounting body 20 and the light-shielding hood body 10. For example, in some embodiments, only one first boss 17 is provided on the light-shielding hood body 10, and only one first groove 28 is provided on the mounting body 20. When the extending direction of the first boss 17 is the first direction, that is, when the insertion direction of the first boss 17 and the first groove 28 is the first direction, the first boss 17 and the first groove 28 are structures that can limit relative rotation with each other after cooperation. For example, the first boss 17 is an elliptical column boss, a polygonal prism boss or a special-shaped boss, etc.; or, in some embodiments, there is an included angle between the extending direction of the first boss 17 and the first direction. Since the end face of the mounting body 20 contacts the end face of the light-shielding hood body 10, the approximate positions of the mounting body 20 and the light-shielding hood body 10 can be determined by the interaction and cooperation after pre-positioning of the mounting body 20 and the light-shielding hood body 10, so that the first connection structure 12 and the second connection structure 22 can be directly aligned, facilitating quick connection and fixation. In some other embodiments, the extending direction of the first boss 17 or the second boss 27 can also be perpendicular to the first direction. At this time, the mounting body 20 and the light-shielding hood body 10 are slidably matched through the adapted first boss 17 and the first groove 28.

[0064] In some embodiments, please refer to Figure 4, a plurality of first bosses 17 are provided on the light-shielding hood body 10 at intervals, and a plurality of first grooves 28 are correspondingly provided on the mounting body 20 at intervals. The first bosses 17 and the first grooves 28 are inserted and matched along the first direction. The plurality means two or more than two. At this time, the first boss 17 can be a cylindrical boss, or an elliptical cylindrical boss, a polygonal prism-shaped boss or a special-shaped boss, etc. The relative positions of the light-shielding hood body 10 and the mounting body 20 are defined by the same number of first bosses 17 and first grooves 28, realizing anti-rotation between the light-shielding hood body 10 and the mounting body 20, so that the first connecting structure 12 and the second connecting structure 22 can be directly aligned, eliminating the step of adjusting the relative positions of the light-shielding hood body 10 and the mounting body 20 to align the first connecting structure 12 and the second connecting structure 22, thereby reducing the assembly difficulty. Since the first magnetic member 11 and the second magnetic member 21 pre-connect the light-shielding hood body 10 and the mounting body 20 together, in the state without external force impact, both hands can be liberated, facilitating the assembly connection of the first connecting structure 12 and the second connecting structure 22.

[0065] In order to further improve the user experience and reduce the assembly difficulty, in some embodiments, please refer to Figure 2 and Figure 3 , in the first direction, the first magnetic member 11 is provided at one end of the light-shielding hood body 10 close to the mounting body 20, and the second magnetic member 21 is correspondingly provided at one end of the mounting body 20 close to the light-shielding hood body 10. By making the first magnetic member 11 and the second magnetic member 21 as close to each other as possible, the acting force of magnetic adsorption can be enhanced, ensuring that the mounting body 20 and the light-shielding hood body 10 are stably connected in the normal state of adsorption. In some embodiments, the insertion direction of the first boss 17 and the first groove 28 can also be set as the first direction, making it consistent with the direction of the magnetic adsorption force, so that the positioning direction and the magnetic adsorption direction are the same. In the case where the first boss 17 and the first groove 28 are aligned, the mounting body 20 can be directly magnetically adsorbed on the light-shielding hood body 10, realizing pre-positioning and pre-connection more quickly, and optimizing the assembly structure of the light-shielding hood kit 100.

[0066] Please refer to Figures 4 - 6, in some embodiments, the light-shielding hood body 10 includes four side walls. The four side walls enclose a first light passage 13 with a rectangular cross-section. From the end far away from the mounting body 20 to the end close to the mounting body 20, the cross-sectional area of the first light passage 13 gradually decreases. Each of the four side walls has a connecting edge extending inward at the second end of the light-shielding hood body 10 to form a connecting end face for connecting the mounting body 20. Four first bosses 17 are arranged at intervals along the circumferential direction of the first light hole on the connecting end face of the light-shielding hood body 10. The four first bosses 17 are arranged in pairs on the connecting edges of two opposite side walls, so that the relative positions of the light-shielding hood body 10 and the mounting body 20 can be positioned more accurately. At the same time, the four first bosses 17 increase the connecting area between the light-shielding hood body 10 and the mounting body 20, which can effectively improve the connecting strength between the light-shielding hood body 10 and the mounting body 20, and thus improve the assembly stability.

[0067] In some embodiments, in order to stably connect and fix the mounting body 20 and the light-shielding hood body 10, both the first connecting structure 12 and the second connecting structure 22 include a plurality of them. Two of the first connecting structures 12 are arranged oppositely on the light-shielding hood body 10 and are located on both sides of the first light passage 13; two of the second connecting structures 22 are arranged oppositely on the opposite sides of the mounting body 20, so as to ensure the connection stability at each point through multi-point connection. At least two of the first connecting structures 12 are arranged on opposite sides, and at least two of the second connecting structures 22 are correspondingly arranged on the opposite sides of the mounting body 20, which at least ensures the reasonable distribution of the fastening force in one direction.

[0068] The first connecting structure 12 and the second connecting structure 22 form a detachable fixation, which means any detachable connection method in the prior art, such as screw connection, fastening connection, snap connection, magnetic attraction connection, etc. The fastening connection refers to a connection method formed by structures such as bolts and screws.

[0069] In some embodiments, in order to further improve the convenience of the light-shielding hood kit 100 and reduce the assembly difficulty, the first connecting structure 12 and the second connecting structure 22 form a quick-release fixation to connect the mounting body 20 and the light-shielding hood body 10. The advantage of the quick-release fixation is that the connection and disassembly can be completed without auxiliary tools, including but not limited to magnetic attraction connection, clamping connection, snap connection, etc., and also includes screws with self-contained knob parts.

[0070] The snap connection is a connection method that can reduce the manufacturing cost, improve the device efficiency and convenience, and is widely used in the fields of machinery, etc. In this embodiment, the snap connection method that can be adopted for the mounting body 20 and the light-shielding hood body 10 is not specifically limited. Any snap element 122 that can achieve snap connection can be adopted, and the structure of the snap element 122 can also refer to any feasible structure in the related art, such as cantilever snap, spherical snap, etc., which will not be elaborated here.

[0071] In some embodiments, please refer to Figure 7 and Figure 8 The first connection structure 12 includes an elastic member 121 and a buckle member 122. The buckle member 122 is movably arranged on the light shielding box body 10. The buckle member 122 has a buckle protrusion 123. The second connection structure 22 is a slot. The elastic member 121 acts on the buckle member 122 to make the buckle protrusion 123 snap into the slot and prevent the buckle protrusion 123 from being separated from the slot. The buckle member 122 can move relatively within a certain range. When the buckle member 122 is acted upon by an external force, it can overcome the force of the elastic member 121 and make the buckle protrusion 123 move in a direction away from the center of the first light passage 13. The installation space for the mounting body 20 and the light shielding box body 10 to be snapped and positioned is reserved, and the cooperation between the first magnetic member 11 and the second magnetic member 21 will not be interfered, so that the mounting body 20 and the light shielding box body 10 can be positioned smoothly. When the fastener 122 is not subjected to external force, the elastic member 121 provides power for the fastener 122 to move toward the slot of the mounting body 20, so that the fastener 122 and the slot remain engaged. The mounting body 20 and the sunshade box body 10 can be quickly assembled or disassembled simply by correspondingly changing the toggle position of the fastener 122 or removing the force on the fastener 122, thereby meeting the needs of frequent assembly and disassembly of the mounting body 20 and the sunshade box body 10.

[0072] It should be noted that, in other embodiments, the first connection structure 12 may also be a slot, and the second connection structure 22 includes an elastic member 121 and a buckle member 122. The structural details can be referred to the above description and will not be described in detail here. Figure 7 Compared with the structure of , the connection method and connection principle have not changed, only the setting position has changed, so quick release can also be achieved.

[0073] The selection of the elastic member 121 and the magnitude of the force of the elastic member 121 can be selected according to actual needs, and the present application does not make specific restrictions. For example, in some embodiments, the buckle 122 can be slidably arranged on the light shielding box body 10, and the elastic member 121 is a compression spring, such as a cylindrical helical compression spring, an annular spring, a disc spring, a torsion spring, etc., and the buckle 122 and the light shielding box body 10 are connected by the compression spring force transmission, and when not affected by external forces, the compression spring presses the buckle 122 against the card slot, and the buckle 122 and the card slot are plugged and matched, thereby limiting the relative position of the mounting body 20 and the light shielding box body 10 in all directions.

[0074] In some embodiments, please refer to Figures 7 - 8, the elastic member 121 is a torsion spring, the buckle member 122 has a buckle protrusion 123, the torsion spring and the buckle member 122 are rotatably arranged on the light-shielding hood body 10 through a rotating shaft 124, and the two acting ends of the torsion spring act on the light-shielding hood body 10 and the buckle member 122 respectively; the card slot is arranged on the side surface of the mounting body 20 for receiving the buckle protrusion 123.

[0075] In some embodiments, please refer to Figure 8 , on the side of the buckle protrusion 123 facing away from the light-shielding hood body 10, there is a guiding inclined surface 1231, and the end of the guiding inclined surface 1231 close to the first light passage 13 is closer to the light-shielding hood body 10 in the first direction than the end of the guiding inclined surface 1231 facing away from the first light passage 13, so that the end of the buckle protrusion 123 facing away from the light-shielding hood body 10 forms a necking structure. A limiting strip 19 is further arranged at one end of the light-shielding hood body 10 facing the mounting body 20. The limiting strip 19 is located on the side of the buckle member 122 close to the first light passage 13. In the state without external force, the limiting strip 19 abuts against the buckle member 122 and is used for bearing the acting force of the elastic member 121 to limit the buckle member 122 from continuing to rotate towards the center of the first light passage 13 after resetting. At one end of the mounting body 20 facing the light-shielding hood body 10, there is an avoidance notch 242 for avoiding the limiting strip 19, so that when the light-shielding hood body 10 is connected to the mounting body 20, the groove surface of the avoidance notch 242 on the mounting body 20 can act on the guiding inclined surface 1231 extending into the avoidance notch 242, so that the buckle member 122 rotates in the direction away from the center of the first light passage 13 to realize the self-installation of the light-shielding hood body 10 and the mounting body 20. Specifically, the limiting strip 19 is generally parallel to the first direction, so that the end surface of the buckle member 122 that can abut against the limiting strip 19 is generally parallel to the first direction. When the user installs the mounting body 20 close to the light-shielding hood body 10, a part of the buckle protrusion extends into the avoidance notch. The groove surface of the avoidance notch 242 of the mounting body 20 can push the guiding inclined surface 1231 in the first direction. Under the action of the guiding inclined surface 1231, the acting force in the first direction is converted into a thrust force, so that the buckle member 122 and the buckle protrusion 123 rotate in the direction away from the center of the first light passage 13. Then, the mounting body 20 can continue to be pressed down towards the direction close to the light-shielding hood body 10. When the mounting body 20 and the light-shielding hood body 10 are attached, the buckle protrusion 123 completely disengages from the avoidance notch 242. Under the action of the torsion spring, the buckle member 122 resets, so that the buckle protrusion 123 is clamped in the card slot, thus quickly realizing the installation. With such a setting, during installation, the user can hold the mounting body 20 close to the light-shielding hood body 10 and does not need to hold the buckle member 122, so the convenience of installation is improved.

[0076] It should be noted that, along the first direction, the limiting strip 19 is located on the side of the buckle protrusion 123 away from the mounting body 20. In addition, the avoidance notch 242 has two openings. One opening faces the light-shielding bucket body 10 along the first direction, and the other opening is located on the side surface of the mounting body 20 and faces the buckle member 122. In some embodiments, in order to reduce the wear generated by the interaction between the guiding inclined surface 1231 and the groove surface of the avoidance notch 242, the groove surface of the avoidance notch 242 relative to the light-shielding bucket body 10 in the first direction can be an inclined surface that cooperates with the guiding inclined surface 1231.

[0077] In some embodiments, both the buckle protrusion 123 and the card slot are square structures. The bottom surface of the buckle protrusion 123 on the side close to the light-shielding bucket body 10 in the first direction is a plane. The top surface and the peripheral surface of the buckle protrusion 123 are both chamfered inclined surfaces. The open ends of the four groove walls of the card slot are all chamfered structures. The smooth alignment and assembly of the buckle protrusion 123 and the card slot are achieved through chamfers. The two relatively groove walls of the card slot in the first direction limit the buckle protrusion 123, realizing the precise positioning of the buckle protrusion 123 in the first direction. At the same time, the other two relatively groove walls of the card slot realize the approximate positioning of the buckle protrusion 123 in the circumferential direction of the light-shielding bucket body 10.

[0078] In some embodiments, in order to further limit the relative positions of the buckle protrusion 123 and the card slot to effectively prevent the buckle protrusion 123 from shaking circumferentially along the light-shielding bucket body 10, please refer to Figure 9 and Figure 10 , the buckle member 122 further has a limiting protrusion 125, and the mounting body 20 further has a limiting groove 29. The limiting groove 29 is communicated with the card slot; along the first direction, the limiting protrusion 125 is arranged on the side of the buckle protrusion 123 close to the light-shielding bucket body 10, and the limiting groove 29 is arranged on the side of the card slot close to the light-shielding bucket body 10; the length of the card slot is greater than the length of the limiting groove 29 to form a stepped surface in the first direction. In other words, the groove wall of the card slot close to the limiting groove 29 in the first direction constitutes a stepped surface. And the length of the limiting groove 29 matches the length of the limiting protrusion 125. The groove wall of the limiting groove 29 is used to clamp the side wall of the limiting protrusion 125 to position the limiting protrusion 125 in the limiting groove 29. At the same time, the existence of the limiting groove 29 does not affect the positioning of the buckle protrusion 123 in the first direction, and the buckle protrusion 123 is still positioned by the two relatively groove walls of the card slot in the first direction.

[0079] It should be noted that, in some embodiments, please refer to Figure 9, the side of the mounting body 20 provided with the card slot and the limiting slot 29 is a plane parallel to the first direction. Both the limiting slot 29 and the card slot are square slots. At this time, the length direction of the limiting slot 29, the first direction, and the depth direction of the limiting slot 29 are perpendicular to each other in pairs. The dimension of the limiting slot 29 in the first direction is understood as the width of the limiting slot 29. Similarly, the length direction of the card slot, the first direction, and the depth direction of the card slot are perpendicular to each other in pairs. The dimension of the card slot in the first direction is understood as the width of the card slot. In some embodiments, along the length direction of the limiting slot 29 and the card slot, the stepped surface may exist only on one side, that is, one end of the card slot is aligned with one end of the limiting slot at this time; in other embodiments, the stepped surface may also exist on both sides, that is, along the length direction of the limiting slot 29 and the card slot, both ends of the limiting slot are located between both ends of the card slot. Please refer to Figure 9 .

[0080] In some embodiments, please refer to Figure 9 and Figure 10 , along the first direction, the limiting slot 29 is located between the card slot and the avoidance notch 242, and both ends of the limiting slot 29 are respectively communicated with the card slot and the avoidance notch 242.

[0081] In some embodiments, the axis of the torsion spring and the axial direction of the rotating shaft 124 may be parallel to the first direction. At this time, in order to improve the installation strength of the torsion spring and the buckle 122, a mounting seat with a strengthening structure may be provided on the light-shielding hood body 10, and the buckle 122 is movably arranged on the mounting seat.

[0082] In order to utilize the self-structural characteristics of the light-shielding hood body 10, reduce the occupied space of the buckle 122, and optimize the overall structure of the light-shielding hood kit 100, in some embodiments, the axis of the torsion spring and the axial direction of the rotating shaft 124 are both perpendicular to the first direction, which can effectively reduce the overall dimension of the buckle 122 in the first direction. Moreover, by utilizing the bucket-shaped structure of the light-shielding hood body 10, when the buckle 122 rotates, the light-shielding hood body 10 can just avoid the buckle 122, and can limit the rotation angle of the buckle 122, which is convenient for applying force.

[0083] Please refer to Figure 4 , in some embodiments, in order to balance the stability of connection and fixation and the convenience of operation, the first connection structure 12 includes two buckles 122 and two elastic members 121. The two buckles 122 are respectively arranged on two opposite side walls of the light-shielding hood body 10, and the second connection structure 22 correspondingly includes two card slots.

[0084] In addition, in some embodiments, please refer to Figure 2The pre-positioning scheme includes the first boss 17 and the first groove 28 adapted to each other, as well as the first magnetic member 11 and the second magnetic member 21. The detachable fixing selects the buckle connection scheme in the above embodiment, and this embodiment can also achieve the advantages of single-person assembly and disassembly. The first boss 17, the torsion spring and the buckle 122 are all arranged on the light-shielding box body 10, and a clearance notch 242 is arranged on the side of the slot of the mounting body 20 close to the light-shielding box body 10 to avoid the buckle 122 when the buckle 122 rotates. It is only necessary to make the number and setting position of the buckle 122 meet the requirements of a single person operating the buckle 122 with one hand or two hands at the same time. For example, the number of the buckle 122 is one or two buckles 122 arranged on different side walls, and a single person manually pulls the buckle 122 in the direction of overcoming the elastic force of the torsion spring. When in use, the mounting body 20 can be inverted first, so that the groove on the end face of the mounting body 20 faces upward, and a single person manually pulls the buckle 122 in the direction of overcoming the elastic force of the torsion spring to form a space for the mounting body 20 and the light shielding box body 10 to be assembled and aligned with each other, and by aligning and plugging multiple groups of first bosses 17 and first grooves 28 at the same time, the positions of the two are determined under the magnetic attraction of the first magnetic attraction member 11 and the second magnetic attraction member 21, and then the buckle 122 is released to make the buckle protrusion 123 engage with the slot. Of course, in other embodiments, the first boss 17 can be replaced by the second groove 18, and the first groove 28 can be replaced by the second boss 27 accordingly, and the effect and use method are the same as above, and the technical effect of assembly and disassembly by a single person can also be achieved.

[0085] In order to install the buckle 122, the torsion spring, the first magnetic member 11 and the second magnetic member 21, in some embodiments, please refer to Figures 4 - 7 The shade box kit 100 also includes two mounting bases 14, which are relatively arranged on the connecting end surfaces of the shade box body 10, and one mounting base 14 is provided with two first bosses 17 and a first magnetic attraction member 11, and the buckle 122 is rotatably connected to the mounting base 14 through a torsion spring and a rotating shaft 124.

[0086] As described in the background technology section, the shade box kit 100 needs to be able to install or replace different filters 200. In some embodiments, a filter slot 241 can be provided at one end of the shade box body 10 close to the mounting body 20. In this case, the shade box body 10 can also have the function of installing the filter 200, and the mounting body 20 is used to connect the lens and the shade box body 10.

[0087] Please refer to Figures 1 - 3, in some embodiments, the mounting body 20 may include a filter mounting body 24 and a lens mounting body 25 connected along a first direction; along the first direction, the lens mounting body 25 has a through hole, and one end of the lens mounting body 25 facing away from the filter mounting body 24 is used for mounting and fixing the lens. The filter mounting body 24 has at least one filter slot 241, and the filter slot 241 communicates with the through hole of the lens mounting body 25. The filter slot 241 and the through hole together form a second light path 23; the second magnetic member is located on the filter mounting body 24, and the filter mounting body 24 forms a detachable connection with the sunshade body 10. When the number of filter slots 241 is two or more, the two or more filter slots 241 are stacked along the first direction. That is, in use, along the first direction, the sunshade body 10, the filter mounting body 24, the lens mounting body 25, and the lens are connected in sequence, and the filter mounting body 24 is located between the sunshade body 10 and the lens mounting body 25. The filter 200 is mounted on the filter mounting body 24, and the lens mounting body 25 is used for mounting and fixing the lens, thereby fixing the entire sunshade kit 100 on the lens. While simplifying the structure of the sunshade body 10, the structure and function of the mounting body 20 are optimized.

[0088] This application does not specifically limit the connection manner between the filter mounting body 24 and the lens mounting body 25. The filter mounting body 24 and the lens mounting body 25 can be fixedly connected or detachably connected. For example, in some embodiments, please refer to Figure 2 and Figure 3 , along the first direction, one side of the filter mounting body 24 facing away from the bucket part is used for connecting the lens mounting part. Specifically, there are four holes on the lens mounting part, and corresponding threaded holes are provided on the filter mounting body 24. The lens mounting part is locked to the filter mounting body 24 by four screws. Two of the screws can also be hand-twist screws. There is also a pressing section for pressing the lens mounting part between the threaded section and the hand-held section of the hand-twist screw. The diameter of the pressing section is larger than the outer diameter of the threaded section, and is used to connect and lock the lens mounting part to the filter mounting body 24.

[0089] In order to facilitate the installation and removal of the filter 200, in some embodiments, please refer to Figures 11 - 13 , along the first direction, a tightening member 26 is threadedly connected to the circumferential surface of the filter mounting body 24. The tightening member 26 is used to screw into the filter slot 241 to tighten the frame of the filter 200. After the filter 200 is installed into the filter slot 241, the tightening member 26 can be tightened, and the tightening member 26 contacts the filter 200, thereby locking the filter 200.

[0090] To preliminarily position the filter 200 before locking the filter 200 through the fastening member 26, in some embodiments, a positioning member 244 for positioning the filter 200 is embedded in the inner peripheral wall of the filter slot 241. The positioning member 244 includes a base, an elastic element, and a ball. The ball is rotatably disposed on the base. Two ends of the elastic element are respectively abutted against the base and the ball. The ball and the elastic element are not fixedly connected, so the ball can rotate around its own center while compressing the elastic element. A part of the ball away from the elastic element extends out of the base and is used to contact the filter 200. The filter 200 installed in the filter slot may include a lens and a lens frame. A positioning hole is provided on the side surface of the lens frame. The positioning hole can be adapted to the ball. Since the ball is spherical, when the ball contacts other positions of the lens frame, the ball compresses the spring and rolls, so that the filter 200 can be smoothly installed into the filter slot 241. When the filter 200 is installed in place, the position of the ball is opposite to the positioning hole, and the elastic element causes the ball to extend into the positioning hole, thereby positioning the position of the filter 200.

[0091] To simplify the structure of the filter mounting body 24 and reduce the weight of the filter mounting body 24, in some embodiments, please refer to Figure 12 and Figure 13 , the filter mounting body 24 is a multi-layer structure, including a base layer 245 and at least one sub-layer 246 that are detachably connected. Along the first direction, the base layer 245 and the at least one sub-layer 246 are stacked. The base layer 245 is located between the sub-layer 246 and the light-shielding hood body 10. The card slot is provided on the side surface of the base layer 245. The light-shielding hood body 10 is snap-connected to the base layer 245. The base layer 245 is a rectangular hollow frame structure, and the filter slots 241 are provided on two opposite sides. The sub-layer 246 includes two mounting strips, and the filter slots 241 are provided on one side of the mounting strips. After adjusting the directions of the filter slots 241 to be consistent, the adjacent base layer 245 and sub-layer 246, and the adjacent sub-layers 246 are positioned and then connected and fixed by threaded members.

[0092] To meet different shooting requirements, in some embodiments, the light-shielding hood kit 100 further includes at least one baffle 30. The baffle 30 is movably disposed at one end of the light-shielding hood body 10 facing away from the mounting body 20, and the baffle 20 can be unfolded during shooting to block light.

[0093] In some embodiments, the baffle 30 can be slidably disposed on the light-shielding hood body 10 or detachably disposed on the light-shielding hood body 10 to block the first light passage 13 when not in use.

[0094] In some embodiments, in order to install the baffle 30 assembly, a threaded support 16 is provided on the outer peripheral surface of the light shield body 10, and the baffle 30 has a connecting shaft 31; the light shield kit 100 further includes a mounting block 40 and a locking member 50. One end of the mounting block 40 is fixedly connected to the threaded support 16, and the other end is rotatably engaged with the connecting shaft 31. The locking member 50 can selectively lock or loosen the connecting shaft 31 and the mounting block 40, so that the baffle 30 can be switched between two states of adjustable angle and fixed position. Through the cooperation of the threaded support 16, the mounting block 40 and the locking member 50, the baffle 30 is rotatably arranged at one end of the first light passage 13 facing away from the second light passage 23, so that the baffle 30 can rotate by a certain angle. When the locking member 50 tightly connects the rotating shaft and the mounting block 40, the baffle 30 cannot rotate. When the locking member 50 creates a gap between the mounting block 40 and the rotating shaft, the baffle 30 can rotate.

[0095] In some embodiments, please refer to Figures 15 - 18 , the number of baffles 30 is four, and four threaded supports 16 are correspondingly and spacedly arranged on the outer peripheral surface of the light shield body 10. Along the circumferential direction of the light shield body 10, four rotating components are spacedly arranged, and the rotating shafts of two adjacent rotating components are perpendicular to each other.

[0096] In some embodiments, the baffle 30 and the connecting shaft 31 can be an integral structure. For the convenience of connection and assembly, in some embodiments, please refer to Figure 17 and Figure 18 , the baffle 30 and the connecting shaft 31 can be inserted and matched and fixedly connected by fasteners, so as to connect the mounting block 40.

[0097] Please refer to Figure 12 , in some embodiments, the mounting body 20 has a mounting bracket 243, and a plurality of threaded interfaces are spacedly arranged on the mounting bracket 243. The plurality of threaded interfaces on the mounting bracket 243 can be used to install extension brackets or accessories, etc. For example, lights can be installed, and the lights can play a role in lighting.

[0098] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 8 , the mounting bracket 243 and the threaded support 16 can cooperate with each other. The mounting bracket 243 extends to the position of the threaded support 16, and the middle part of the mounting bracket 243 is a concave structure. The threaded support 16 has a clamping part for fitting the concave structure. The middle part of the end of the mounting block 40 away from the connecting shaft 31 is a convex structure matching the concave structure. On the one hand, the clamping part can avoid the concave structure, and on the other hand, the concave structure and the clamping part can also assist in positioning the mounting body 20 and the light shield body 10.

[0099] To meet the requirements of high photographic quality, a hard matte can be installed in the first light passage 13 of the lens hood body 10, and the hard matte can block unnecessary scattered light. In some embodiments, please refer to Figure 5 , the lens hood body 10 has an inner cavity with an opening facing away from the mounting body, and the lens hood body 10 also has a light passage hole with an opening facing the mounting body 20. The light passage hole and the inner cavity are opposite and communicated in the first direction to form the first light passage 13; the lens hood kit 10 also includes a hard matte, which is installed in the inner cavity of the lens hood body 10. A limiting portion 15 for preventing the hard matte from detaching from the lens hood body 10 is provided on the inner cavity wall of the lens hood body 10. While realizing the stable installation of the hard matte, the structure of the lens hood body 10 is also simplified. It should be noted that Figure 5 the hard matte is not shown in

[0100] In actual use, the lens hood kit 100 will be used in combination with external structures such as a pan-tilt kit and a stabilizer kit. In some embodiments, please refer to Figures 19 - 22 , the lens hood kit 100 also includes an angle adjustment mechanism 60. The angle adjustment mechanism 60 includes a first connecting member 61, a second connecting member 62, and an adjustment assembly 63: The second connecting member 62 is fixedly connected to the lens hood body 10 or the mounting body 20, and the second connecting member 62 is rotatably connected to the first connecting member 61. The first connecting member 61 is used to mount the lens hood kit 100 on the external structure; the adjustment assembly 63 includes a first adjustment rotating shaft 631, a second adjustment rotating shaft 632, and an adjustment member 633. The first adjustment rotating shaft 631 is rotatably provided on the first connecting member 61, the second adjustment rotating shaft 632 is rotatably provided on the second adjustment member 633. Both the first adjustment rotating shaft 631 and the second adjustment rotating shaft 632 are arranged parallel to the rotation axis of the second connecting member 62. The adjustment member 633 is threadedly connected to at least one of the first adjustment rotating shaft 631 and the second adjustment rotating shaft 632, and is used to adjust the angle between the first connecting member 61 and the second connecting member 62 when rotating. By rotating the adjustment member 633, the distance between the first adjustment rotating shaft 631 and the second adjustment rotating shaft 632 can be adjusted, that is, the angle between the first connecting member 61 and the second connecting member 62 can be adjusted, so that the first connecting member 61 and the second connecting member 62 rotate relative to each other, so that the lens hood kit 100 connected to the second connecting member 62 is at different angles relative to the first connecting member 61 to meet the angle adjustment requirements during the use of the lens hood kit 100.

[0101] In some embodiments, please refer to Figures 21 - 22 , in order to facilitate the replacement of some accessories on the light shield kit 100, the second connecting member 62 includes a limiting member 621, a first connecting unit 622 and a second connecting unit 623. The second connecting unit 623 is rotatably connected to the first connecting unit 622. The rotation axis between the second connecting unit 623 and the first connecting unit 622 is perpendicular to the rotation axis between the first connecting unit 622 and the first connecting member 61. The limiting member 621 is used to lock or unlock the rotation state between the first connecting unit 622 and the second connecting unit 623. The limiting member 621 is movably arranged on the first connecting unit 622 or the rotating connecting portion. The limiting member 621 has an unlocking state and a locking state and can be switched between the unlocking state and the locking state. When the limiting member 621 is in the locking state, the second connecting unit 623 is locked to the first connecting unit 622. When the limiting member 621 is in the unlocking state, the second connecting unit 623 can rotate relative to the first connecting unit 622. With such a setting, when it is necessary to replace some accessories on the light shield kit 100, the position of the second connecting unit 623 relative to the first connecting unit 622 can be rotated and adjusted, so that there is a larger space for the user to install and replace the required accessories.

[0102] For example, in some embodiments, the limiting member 621 is an elastic and retractable limiting button arranged on the first connecting unit 622. A limiting card slot is arranged on the second connecting unit 623. When the limiting button is pressed, the limiting button can withdraw from the limiting card slot, so that the second connecting unit 623 can rotate relative to the first connecting unit 622. With such a setting, when it is necessary to install or replace the accessories on the light shield kit 100, the limiting member 621 is adjusted to the unlocking state, and the second connecting unit 623 is rotated to a suitable position. After the replacement is completed, the second connecting unit 623 is adjusted to reset, and the limiting member 621 is adjusted back to the locking state, so that the angle adjustment structure of the light shield kit 100 returns to the normal use state. It can not only meet the needs of accessory installation and replacement, but also effectively avoid the accidental deflection of the second connecting unit 623 during normal use.

[0103] In some embodiments, in order to stably connect the external structure and the angle adjustment mechanism 60, the light shield kit 100 further includes a clamping mechanism 70. Please refer to Figure 20 , Figure 23 and Figure 24, the clamping mechanism 70 includes a connection main body 71 and a linkage assembly 72; one end of the connection main body 71 has a clamp clamping portion 711, and the other end has an installation groove 712. The first connecting member 61 is installed in the clamp clamping portion 711; the linkage assembly 72 includes a locking block 721 and a linkage adjusting member 722. The locking block 721 is slidably disposed in the installation groove 712, and the linkage adjusting member 722 is disposed on the connection main body 71. The output end of the linkage adjusting member 722 is drivingly connected to the locking block 721 for driving the locking block 721 to slide in the installation groove 712 so as to press the connecting portion of the external structure against the groove wall of the installation groove 712.

[0104] The present utility model does not limit the specific solution of the linkage adjusting member 722 and can be any feasible solution. For example, in some embodiments, the linkage adjusting member 722 can be a bolt threadedly connected to the connection main body 71, and the axial direction of the bolt is the same as the sliding direction of the locking block 721 in the installation groove 712, so as to push the locking block 721. In other embodiments, the linkage adjusting member 722 can also be a ball screw structure, and the locking block 721 is connected to the linear moving component of the ball screw structure, so as to drive the locking block 721 to slide along the installation groove 712. That is to say, all structures that can change the position of the locking block 721 in the installation groove 712 can be regarded as the linkage adjusting member 722.

[0105] As an implementation manner, please refer to Figure 23 and Figure 24, both ends of the installation groove 712 are provided with through round holes, which are suitable for the connection and fixation of an external structure with a connecting round tube. The number of locking blocks 721 is two. The end of the locking block 721 close to the round hole is in a semi-circular arc shape, forming a holding surface that matches the shape of the connecting round tube. The end of the locking block 721 facing away from the round hole is an inclined guiding slope. The linkage adjusting member 722 includes a locking knob 723, a spring 724, and a linkage block 725. The locking knob 723 is threadedly connected to the connecting body 71, and one end extends into the installation groove 712. The linkage block 725 is arranged in the installation groove 712 and is located between the two locking blocks 721. Along the sliding direction of the locking block 721, both ends of the linkage block 725 have contact surfaces that respectively cooperate with the guiding slopes of the two locking blocks 721. The linkage block 725 is threadedly connected to the rod portion of the locking knob 723. The spring 724 is sleeved on the rod portion of the locking knob 723. The spring 724 acts on the linkage block 725 and the groove wall of the installation groove 712. By rotating the locking knob 723, under the action of the guiding slope and the contact surface, the linkage block 725 cannot rotate, and the linkage block 725 moves relative to the locking knob 723, thereby squeezing the locking blocks 721 apart to lock the connecting round tube of the external structure. There is a spring 724 between the linkage block 725 and the groove wall of the installation groove 712 to ensure the structural stability.
