Description

Technical Field

[0001] The invention relates to the technical field of cameras, and in particular to a novel aperture structure. Background Art

[0002] The camera's aperture is a key component for controlling exposure time. Its function is to determine the exposure of the image by controlling the time it takes for light to enter the camera sensor or film. The opening and closing speed of the aperture directly affects the brightness and clarity of the image, and is an important means to achieve correct exposure. During the camera's shooting process, the action of the aperture must be precise and reliable, especially in high-speed photography or scenes that require precise exposure control. The main function of the magnetic valve set on the aperture is to control the opening and closing of the aperture curtain through electromagnetic induction, which can perform the aperture action more quickly and stably, thereby achieving a higher aperture speed and lower operating noise. The introduction of the magnetic valve not only improves the durability of the aperture, but also maintains excellent performance in extreme shooting environments. Especially in high-speed continuous shooting or shooting tasks that require extremely short exposure times, the magnetic valve plays a vital role, ensuring the efficient operation of the camera and excellent image quality.

[0003] But the problem now is that the existing magnetic valve is fixed on the aperture fixing seat by gluing, which may cause the risk of glue leakage and is inconvenient to disassemble and install. If the magnetic valve assembly is damaged, the magnetic valve cannot be disassembled and the entire aperture structure needs to be replaced, resulting in a huge waste of resources.

[0019] In order to make the content of the present invention more clearly understood, the present invention is further described below based on specific embodiments in conjunction with the accompanying drawings.

[0020] It should be noted that the terms "center", "upper", "lower", "front", "back", "left", "right", "inner", "outer" and the like used herein to indicate directions or positional relationships are based on directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. Unless otherwise specified, "plurality" means two or more.

[0021] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0022] like Figures 1 to 5 As shown, an embodiment of the present invention provides a new aperture structure, including an aperture body 1, the aperture body 1 includes a fixing seat 11, a mounting position 12 and a magnetic valve assembly 2 are provided on the fixing seat 11, a clamping member 3 is provided at one end of the magnetic valve assembly 2 facing the mounting position 12, and at least one buckle 31 is provided on the side wall of the clamping member 3, and the magnetic valve assembly 2 is clamped in the mounting position 12 through the buckle 31.

[0023] Specifically, in the embodiment of the present application, an optical device for taking pictures is arranged inside the aperture body 1, and the aperture body 1 includes a fixing seat 11, and the fixing seat 11 is used to install the magnetic valve assembly 2 and other optical devices. The mounting position 12 can be set at the edge position of one end of the fixing seat 11, and is used to install the magnetic valve assembly 2. One end of the magnetic valve assembly 2 is provided with a clamping member 3, and one end of the clamping member 3 is fixedly connected to the magnetic valve assembly 2, and the other end is clamped in the mounting position 12. At least one buckle 31 is arranged on the side wall of the clamping member 3, and the buckle 31 can be set to one or two. The magnetic valve assembly 2 is clamped in the mounting position 12 through the buckle 31, so that the magnetic valve assembly 2 can be fixedly connected to the fixing seat 11, avoiding the traditional method of fixing the magnetic valve assembly 2 and the fixing seat 11 with glue, thereby avoiding the problem of forgetting to glue, and improving the stability of the magnetic valve assembly 2 and the fixing seat 11. At the same time, since the magnetic valve assembly 2 is fixed to the fixing seat 11 by the buckle 31, it can be easily disassembled. For example, when the magnetic valve is damaged, it is not necessary to replace the entire aperture body 1, but only the magnetic valve assembly 2 needs to be removed and replaced, thus avoiding waste of resources.

[0024] In a possible embodiment, an external thread can be set on the outer wall of the magnetic valve assembly 2, and an internal thread can be set on the inner ring wall of the installation position 12. By threading the magnetic valve assembly 2 and the fixing seat 11, the magnetic valve assembly 2 and the fixing seat 11 can be installed more firmly and disassembly can be further facilitated.

[0025] like Figure 3 , Figure 7 as well as Figure 8 As shown, a through hole 121 and a slot 122 are provided at intervals at the bottom of the mounting position 12 . The slot 122 is provided on one side of the through hole 121 away from the bottom of the mounting position 12 . The buckle 31 passes through the through hole 121 and is connected to the slot 122 .

[0026] Specifically, in the embodiment of the present application, the mounting position 12 is roughly circular and recessed inwardly for mounting the magnetic valve assembly 2. Two elongated through holes 121 are provided at the bottom of the mounting position 12. The above-mentioned slots 122 are arranged at the bottom of the mounting position 12 and on the side away from the magnetic valve assembly 2, and are located on both sides of the two through holes 121. The above-mentioned buckle 31 passes through the bottom of the mounting position 12, and the buckle 31 is buckled on the slot 122, so that the snap-on component 3 and the fixing seat 11 can be easily snapped and fixed. In the above manner, when the magnetic valve assembly 2 needs to be replaced, it is only necessary to push the buckle 31 away from the slot 122. In this way, the snap-on component 3 can be detached from the fixing seat 11, and then the magnetic valve assembly 2 can be detached from the fixing seat 11, thereby improving the convenience of replacing the magnetic valve assembly 2. At the same time, it is also possible to observe whether the buckle 31 on the snap-on component 3 is snapped into place, thereby avoiding the magnetic valve being not installed in place, resulting in the appearance of defective products.

[0027] like Figure 4 , Figure 5 as well as Figure 7 As shown, it also includes a magnetic valve cover plate 4, which covers the installation position 12 and faces away from the magnetic valve assembly 2. The magnetic valve cover plate 4 is clamped with the fixing seat 11 and the side wall close to the installation position 12.

[0028] Specifically, the embodiment of the present invention also includes a magnetic valve cover plate 4, which covers the side of the installation position 12 away from the magnetic valve assembly 2. By clamping the magnetic valve cover plate 4 with the side wall of the installation position 12, and at the same time abutting the two sides of the magnetic valve cover plate 4 with the buckle 31, it is possible to further prevent the buckle 31 and the slot 122 from falling off, increase the stability of the magnetic valve assembly 2 and the fixed seat 11, prevent the buckle 31 and the slot 122 from slipping when the embodiment is dropped or impacted, and improve the durability of the embodiment.

[0029] In a possible embodiment, a screw hole can be opened at the edge of the fixing seat 11 and close to the mounting position 12, and a second screw hole can be opened on the magnetic valve cover plate 4 at a position opposite to the screw hole. The magnetic valve cover plate 4 can be fixed to the fixing seat 11 by screws, thereby preventing the magnetic valve cover plate 4 from falling off, thereby further ensuring that the buckle 31 and the slot 122 fall off, and improving the stability between the magnetic valve assembly 2 and the fixing seat 11.

[0030] like Fig. 9 As shown, the magnetic valve cover plate 4 includes a plate body 41 and a retaining ring 42 arranged on opposite sides of the plate body 41 . A first protrusion 111 is arranged on the side wall of the fixing seat 11 near the mounting position 12 , and the retaining ring 42 is clamped to the first protrusion 111 . Specifically, in the embodiment of the present application, the magnetic valve cover sheet 4 is roughly rectangular, the sheet body 41 can be a rectangular sheet, the clamping ring 42 is arranged on the two shorter sides of the sheet body 41 and is perpendicular to the sheet body 41, and the first protrusion 111 is arranged on both sides of the installation position 12. By covering the sheet body 41 on the side of the fixing seat 11 away from the installation position 12, the clamping ring 42 can be clamped on the first protrusion 111, thereby facilitating the fixing of the magnetic valve cover sheet 4. In addition, the above-mentioned clamping method can also facilitate the removal of the magnetic valve cover sheet 4.

[0031] like Figure 5 , Fig. 9 As shown, a limiting hole 411 is provided in the middle of the sheet body 41 , and a limiting column 123 is provided at a position corresponding to the limiting hole 411 in the mounting position 12 , and the limiting column 123 passes through the limiting hole 411 .

[0032] Specifically, in the embodiment of the present application, since two through holes 121 are opened in the installation position 12, a spacer can be formed, and a limiting column 123 is arranged on the spacer. The limiting column 123 is arranged on the side of the spacer facing the magnetic valve cover plate 4, and a limiting hole 411 is arranged in the middle position of the sheet body 41. The sheet body 41 is installed on the limiting column 123 through the limiting hole 411, which can prevent misalignment when installing the magnetic valve cover plate 4 and can better enable the magnetic valve cover plate 4 to be installed on the fixed seat 11.

[0033] like Figure 4 , Figure 5 As shown, a gear box cover 112 is provided on a side of the fixing seat 11 facing away from the magnetic valve assembly 2 , and the gear box cover 112 is snap-connected to the side wall of the fixing seat 11 .

[0034] Specifically, in the embodiment of the present application, a gear box is provided in the fixing seat 11. Since the gear box needs to be sealed, a gear box cover 112 needs to be provided to seal the gear box. The existing gear box cover 112 is usually fixed by screws. However, since the gear box needs multiple screws to be fixed, the operable space of the aperture structure is relatively small, so it is not convenient to screw in the screws, and there may be a risk of missing the screws. By providing the gear box cover 112 and snapping it with the side wall of the fixing seat 11, the gear box cover 112 can be snapped and fixed to the fixing seat 11, thereby avoiding the risk of missing the screws and the possibility that the screws may be glued to other parts of the present embodiment by glue during the installation process.

[0035] Further, such as Figure 5 and Figure 7 As shown, at least one second protrusion 113 is provided on the side wall of the fixing seat 11 close to the gear box cover 112 , and a hook is provided at the edge of the gear box cover 112 and corresponding to the position of the second protrusion 113 , and the hook is engaged with the second protrusion 113 .

[0036] Specifically, in the embodiment of the present invention, at least one second protrusion 113 is provided on the side wall of the fixing base 11, and the second protrusion 113 can also be set to two or three. A hook 1121 is extended at the edge of the gear box, and the position of the hook 1121 arranged on the gear box cover 112 corresponds to the position of the second protrusion 113. By setting the hook 1121 to engage with the second protrusion 113, the gear box cover 112 can be engaged with the second protrusion 113, so that disassembly and installation are facilitated and the occurrence of screw omissions is prevented. like Fig.10 As shown, the magnetic valve assembly 2 further includes a round iron 21 and a magnet 22 disposed in the round iron 21 . A mounting portion 221 is provided on a side wall of the magnet 22 , and the clamping member 3 is fixedly connected to the mounting portion 221 .

[0037] Specifically, in the embodiment of the present invention, the magnetic valve assembly 2 includes a round iron 21 and a magnet 22. The magnet 22 is arranged in the round iron 21. Through the electromagnetic relationship between the round iron and the magnet 22, the magnet 22 can be swung to control the crank, thereby realizing the power on and off of the magnetic valve assembly 2. A mounting hole 2221 is provided on the side wall of the magnet 22, and the clip 3 is fixedly connected to the mounting portion 221. Specifically, a stud 32 is provided at one end of the clip 3 facing the mounting hole 2221. The clip 3 is screwed in the mounting hole 2221 through the stud 32, thereby enabling the clip 3 to be fixedly connected to the magnetic valve assembly 2.

[0038] Further, such as Fig.10As shown, the magnet 22 includes a base 222, an enameled wire 223 wound on the base 222, a magnet 224 and a crank for controlling the on / off power of the magnetic valve assembly 2 are also arranged inside the base 222, a mounting hole 2221 is arranged on the side wall of the base 222, and a stud 32 is arranged at one end of the clamping part 3 facing the mounting hole 2221, and the stud 32 is screwed into the mounting hole 2221.

[0039] Specifically, in an embodiment of the present invention, the above-mentioned magnet 22 may include a base 222 and an enameled wire 223, the enameled wire 223 is wound on the base 222, and a magnet 224 and a crank are also arranged inside the base 222, and the crank is used to control the on / off power of the magnetic valve assembly 2. In this way, through the above-mentioned scheme, the magnetic valve assembly 2 can control the crank assembly to swing, thereby realizing the shooting function of the aperture structure.

[0040] like Figure 1 As shown, the conductive member 5 is used to supply power to the magnetic valve assembly 2, so as to control the crank in the magnetic valve assembly 2. Specifically, the conductive member 5 may be an FPC. The conductive member 5 may be electrically connected to the end of the magnetic valve assembly 2 away from the fixing seat 11. By setting the conductive member 5 as an FPC, it can be lighter and thinner than a traditional rigid circuit board, suitable for miniaturized design, bendable and foldable, and convenient for installation in an aperture structure.

[0041] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks.
