Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 16 As shown, an embodiment of the present invention provides an aperture elastic blade, comprising:

[0037] The system comprises an elastic blade body 11 and an elastic blade limiting part 12, the elastic blade limiting part 12 being connected to the elastic blade body 11. The elastic blade body 11 is provided with an elastic blade rotation hole 111 and an elastic blade rotation guide groove 112. The elastic blade rotation hole 111 is rotatably connected to an aperture elastic blade connecting post 225 on an aperture structure, and the elastic blade body 11 is driven to rotate relative to the aperture structure for aperture adjustment through an aperture adjustment guide post 3121 connected to the aperture structure via the elastic blade rotation guide groove 112. One end of the elastic blade limiting part 12 is connected to the elastic blade body 11, and the other end is connected to the aperture structure to limit and adjust the aperture of the elastic blade body 11.

[0038] Specifically, the elastic blade limiting part 12 is integrally formed with the elastic blade body 11. On the one hand, the integral forming is produced by etching process, which can accurately manufacture the shape and structure of the aperture elastic blade, resulting in fast and low-cost production; it can also improve the stability and accuracy of the structure, reduce errors in the assembly process, and thus improve the consistency and reliability of the aperture elastic blade; on the other hand, the integral forming design eliminates the need for elastic component connection holes on the aperture elastic blade and the need to design separate elastic components to be connected in the elastic component connection holes for limiting, reducing processing and assembly steps, effectively reducing product production costs and improving production convenience; the elastic blade limiting part 12 adopts a planar design, and the overall thickness of the elastic blade limiting part 12 is reduced by increasing the width on both sides, ensuring the elastic deformation of the elastic blade limiting part 12 while reducing production costs; and the elastic blade limiting part 12 is provided with an elastic fixing part 121 and an elastic tensioning part 122, the elastic The tensioning section 122 is provided with a first elastic direct connection end 1221, a second elastic direct connection end 1222, and a middle elastic deformation end 1223; the middle elastic deformation end 1223 is designed in an S-shape, which can effectively increase the elastic deformation of the middle elastic deformation end 1223 to increase the elastic force; one end of the middle elastic deformation end 1223 is connected to the first elastic direct connection end 1221, and the other end is connected to the second elastic direct connection end 1222; the first elastic direct connection end 1221 is connected to the elastic leaf. The main body 11; the elastic fixing part 121 is connected to the aperture structure and connected to the second elastic direct connection end 1222; the first elastic direct connection end 1221 and the second elastic direct connection end 1222 are respectively connected to the two sides of the middle elastic deformation end 1223 to form a limiting angle α, and the aperture limiting adjustment is achieved by changing the limiting angle α to drive the middle elastic deformation end 1223 to undergo elastic deformation; in this embodiment of the invention, the angle range of the limiting angle α is preferably 0°≤α<90°.

[0039] When the aperture elastic blades are not assembled, the limiting angle α between the first elastic direct connection end 1221 and the second elastic direct connection end 1222 is 0°, leaving the middle elastic deformation end 1223 in a free state to extend the service life of the aperture elastic blades. When assembled on the aperture structure, the limiting angle α between the first elastic direct connection end 1221 and the second elastic direct connection end 1222 is greater than 0°, leaving the middle elastic deformation end 1223 in a stretched state to provide a first elastic force to pull the elastic blade body 11 towards the connection between the elastic fixing part 121 and the aperture structure, thereby eliminating the connection gap between the elastic blade rotation hole 111 and the aperture elastic blade connecting post 225, and between the elastic blade rotation guide groove 112 and the aperture adjustment guide post 3121, thus ensuring that multiple elastic blade bodies 11 are connected to the aperture. Structurally, the light transmission is kept consistent when connected to the same position to improve the accuracy of aperture elastic blade adjustment. When adjusted on the aperture structure, the limiting angle α between the first elastic direct connection end 1221 and the second elastic direct connection end 1222 is still greater than 0°, so that the middle elastic deformation end 1223 is in a stretched state, providing a first elastic force to pull the elastic blade body 11 towards the connection between the elastic fixing part 121 and the aperture structure, thereby eliminating the connection gap between the elastic blade rotation hole 111 and the aperture elastic blade connecting post 225 and the elastic blade rotation guide groove 112 and the aperture adjustment guide post 3121, thus ensuring that the light transmission is consistent when multiple elastic blade bodies 11 are connected to the aperture structure and adjusted to the same position, thereby improving the accuracy of aperture elastic blade adjustment.

[0040] Furthermore, the elastic fixing part 121 is connected to the aperture elastic blade connecting post 225 adjacent to the elastic blade rotation hole 111 for aperture limiting adjustment, so as to ensure that the elastic blade body 11 can be tightened by the elastic fixing part 121 after adjustment or reset, thereby eliminating the connection gap between the elastic blade rotation hole 111 and the aperture elastic blade connecting post 225 and the elastic blade rotation guide groove 112 and the aperture adjustment guide post 3121, ensuring that the light transmission of multiple aperture elastic blades is consistent after adjustment, so as to improve the adjustment accuracy; the connection between the elastic fixing part 121 and the aperture elastic blade connecting post 225 adopts an anti-loosening design to prevent the connection from becoming loose due to vibration or impact during long-term use, thereby improving the stability of the connection.

[0041] The elastic blade body 11 of this invention is designed to resemble an eagle's beak, so that the concave portions of multiple elastic blade bodies 11 can be arranged to form an aperture that decreases in size or increases in size, thereby improving the ease of adjustment.

[0042] This invention also provides an automatically adjusting aperture structure, including an aperture support 2, an aperture driving module, and an aperture elastic blade as described above; since the automatically adjusting aperture structure also has an aperture elastic blade, it also has the same technical effect as the aperture elastic blade.

[0043] Furthermore, the aperture driving module is connected within the aperture support 2, and the aperture driving module includes an aperture rotating disk and an aperture FPC coil structure. The aperture rotating disk includes an aperture rotating magnet group and an aperture rotating disk body 312. The aperture rotating magnet group is connected to the aperture rotating disk body 312, and the aperture rotating magnet group 31 is made of a high magnetic material to enhance its driving efficiency and improve the response speed of aperture adjustment. Multiple aperture elastic blades 1 are connected to the aperture support 2 through the elastic blade rotation holes 111. The aperture rotating disk body 312 is connected within the elastic blade rotation guide groove 112. After the aperture FPC coil structure is energized, it drives the aperture rotating disk body 312 to rotate forward or backward, causing the aperture rotating disk body 312 to drive multiple aperture elastic blades 1 to rotate through the elastic blade rotation guide groove 112. This allows the multiple aperture elastic blades 1 to form an aperture that decreases in size or increases in size, thereby improving the convenience of adjustment.

[0044] Furthermore, the aperture adjustment guide post 3121 is disposed on the aperture rotating disk body 312, and multiple aperture adjustment guide posts 3121 are designed at equal angles along the middle of the aperture rotating disk body 312, so that multiple aperture elastic blades 1 can be rotated at equal angles through the aperture adjustment guide post 3121 to adjust the aperture, thereby improving the stability of the adjustment; the aperture rotating disk body 312 is also provided with a rotating magnet mounting part 3122, which is symmetrically disposed on both sides of the aperture rotating disk body 312, and a rotating magnet mounting groove 31221 is provided on the inner side of the rotating magnet mounting part 3122; the aperture rotating magnet group is provided with a first aperture rotating magnet 3111 and a second aperture rotating magnet 3112. The first aperture rotating magnet 3111 and the second aperture rotating magnet 3112 are respectively connected to the rotating magnet mounting grooves 31221 on both sides by special magnet adhesive. The rotating magnet mounting grooves 31221 axially limit the first aperture rotating magnet 3111 and the second aperture rotating magnet 3112 to prevent the first aperture rotating magnet 3111 and the second aperture rotating magnet 3112 from shifting or falling off during rotation, which would affect the normal operation of the aperture structure. This drives the aperture rotating disk body 312 to rotate stably and ensures the stability of operation. The aperture rotating disk body 312 is also provided with an aperture rotating disk light passage hole 3123 in the middle to ensure that light can enter the next component through the aperture rotating disk light passage hole 3123.

[0045] Furthermore, the aperture FPC coil structure includes an aperture FPC coil structure body 321, an aperture adjustment coil group, and an aperture reset magnet 323. The aperture FPC coil structure body 321 includes an FPC coil mounting part 3211 and a reset magnet mounting part 3212, with the FPC coil mounting part 3211 corresponding to the rotating magnet mounting part 3122. The aperture adjustment coil group includes a first aperture adjustment coil 3221 and a second aperture adjustment coil 3222. The first aperture adjustment coil 3221 and the second aperture adjustment coil 3222 are respectively connected to the FPC coil mounting part 3211 by coil conductive adhesive or welding. The first aperture adjustment coil 31 and the second aperture adjustment coil 3222 are respectively arranged corresponding to the first aperture rotating magnet 3111 and the second aperture rotating magnet 3112. When the first aperture adjustment coil 3221 and the second aperture adjustment coil 3222 are energized, a driving magnetic field is generated. By controlling the magnitude of the energizing current of the first aperture adjustment coil 3221 and the second aperture adjustment coil 3222, the driving magnetic field provides a reaction force to the first aperture rotating magnet 3111 and the second aperture rotating magnet 3112, thereby driving the aperture rotating disk to rotate and adjust the multiple aperture elastic blades 1, thus improving the convenience of automatic adjustment. The aperture reset magnet 323 is made of soft magnetic material, preferably in this embodiment of the invention. One type of magnetic field is connected to the inner side of the reset magnet mounting part 3212 using special magnetic adhesive. This allows the aperture rotating disk to be reset by the aperture reset magnet 323 after the first aperture adjustment coil 3221 and the second aperture adjustment coil 3222 are de-energized, by attracting the first aperture rotating magnet 3111 or the second aperture rotating magnet 3112. This eliminates the need for a drive motor for reset, optimizes the structure, reduces the overall weight, and improves the convenience and environmental friendliness of automatic reset adjustment. The aperture FPC coil structure also includes a Hall sensor 324, which is connected inside the first aperture adjustment coil 3221 or the second aperture adjustment coil 3222 to activate the magnetic field. The position of the sensing magnet is used to sense the rotation angle of the turntable, thereby obtaining the size of the opening formed by the multiple aperture elastic blades 1, thus improving the accuracy of the automatic aperture adjustment; the aperture FPC coil structure body 321 is also provided with a power connection port 3213 and a coil illumination through hole 3214. The aperture FPC coil structure is connected to an external power source through the power connection port 3213; the coil illumination through hole 3214 cooperates with the aperture turntable light transmission hole 3123 to allow external light to enter, so as to adjust the amount of light transmitted through the multiple aperture elastic blades 1; the aperture FPC coil structure body 321 is made of flexible material to improve its adaptability and fatigue resistance, and extend its service life.

[0046] Furthermore, the aperture support 2 is provided with an aperture support cover 21 and an aperture support fixing seat 22. The aperture driving module is connected to the aperture support fixing seat 22, and the aperture support cover 21 is connected to the aperture support fixing seat 22 to fasten the aperture driving module inside the aperture support 2. Both the aperture support cover 21 and the aperture support fixing seat 22 are made of thermally conductive materials to improve the overall heat dissipation performance of the aperture structure and ensure long-term use of the aperture structure.

[0047] Furthermore, multiple aperture elastic blade connecting posts 225 are equally angled on the aperture support fixing base 22, so that the multiple aperture elastic blades 1 can rotate uniformly after being connected, ensuring the accuracy of adjustment; the aperture support fixing base 22 is provided with an FPC coil power connection port mounting position 220, an aperture support upper cover mounting position 221, an aperture rotating disk limiting groove 222, an aperture FPC coil structure mounting position 223, an aperture FPC coil structure limiting post 224, an aperture elastic blade rotation limiting groove 226, and an aperture support upper cover fixing buckle 227; the aperture FPC coil structure body 321 is also provided with an FPC coil structure limiting post. The FPC coil mounting part 3211 and the power connection port 3213 are respectively positioned and connected to the aperture support fixing base 22 through the aperture FPC coil structure mounting position 223 and the FPC coil power connection port mounting position 220, and are engaged with the aperture FPC coil structure limiting post 224 through the FPC coil structure limiting post mounting hole 3215, thereby fixing the aperture FPC coil structure to the aperture support fixing base 22, so as to ensure that the aperture FPC coil structure will not rotate due to the reaction force of the aperture adjustment coil group after power is applied, and to ensure the stability of the aperture structure adjustment;

[0048] The aperture rotating disk body 312 is connected to the aperture support fixing seat 22 through the aperture rotating disk limiting groove 222, and the aperture rotating disk body 312 is limited by the aperture rotating disk limiting groove 222 to prevent the aperture rotating disk body 312 from exceeding the maximum rotation range during rotation, which would damage the aperture structure and improve the overall connection reliability.

[0049] The aperture drive module also includes an aperture component partition 33. The aperture component partition 33 is provided with an aperture component light-passing hole 331 and a plurality of aperture component partition limiting holes 332 corresponding one-to-one with the aperture adjustment guide post 3121. The aperture component partition 33 is connected to the aperture adjustment guide post 3121 through the aperture component partition limiting holes 332, thereby fixing the aperture component partition 33 to the aperture rotating disk body 312, so as to separate the plurality of aperture elastic blades 1 from the aperture rotating disk body 312. This not only reduces the friction between the plurality of aperture elastic blades 1 and the aperture rotating disk body 312, but also supports the plurality of aperture elastic blades 1, preventing the plurality of aperture elastic blades 1 from radially shifting before and after adjustment, thus affecting the stability of aperture adjustment.

[0050] The elastic blade rotation hole 111 is connected to the aperture elastic blade connecting post 225, so that the multiple aperture elastic blades 1 are rotatably connected to the aperture support fixing seat 22, and are limited by the aperture elastic blade rotation limiting groove 226.

[0051] The aperture elastic blade rotation limiting groove 226 is designed to mimic the aperture elastic blade to prevent damage to the aperture elastic blade 1 during rapid rotation, while also preventing it from exceeding the maximum rotation range, thus enhancing the durability of the aperture elastic blade 1. The aperture support cover 21 is fixedly connected to the aperture support fixing seat 22 via the aperture support cover mounting position 221 and the aperture support cover fixing buckle 227 to secure the components of the aperture drive module, preventing the components from falling off during adjustment and affecting the overall structural operation of the aperture structure.

[0052] The aperture support and fixing base 22 is also provided with an aperture turntable rotating protrusion 228 and a support and fixing base light transmission hole 229. The aperture turntable body 312 can abut against the aperture turntable rotating protrusion 228 to reduce the friction between the aperture turntable body 312 and the aperture support and fixing base 22, and extend the service life of the aperture turntable body 312. The support and fixing base light transmission hole 229 can cooperate with the coil illumination through hole 3214 to ensure normal light intake and facilitate adjustment of the light transmission amount.

[0053] Furthermore, the aperture support cover 21 is provided with a cover fixing buckle connection position 211 and an aperture support fixing seat positioning part 212; the aperture support cover 21 is positioned and connected to the aperture support cover mounting position 221 through the aperture support fixing seat positioning part 212, and is connected to the aperture support cover fixing buckle 227 through the cover fixing buckle connection position 211 to fasten the aperture support cover 21 to the aperture support fixing seat 22;

[0054] The aperture support cover 21 is also provided with an aperture elastic blade connecting post mating hole 213, an aperture adjustment guide post mating groove 214, an aperture elastic blade rotating protrusion 215, and an aperture cover light-transmitting hole 216. The aperture support cover 21 is connected to the aperture elastic blade connecting post 225 through the aperture elastic blade connecting post mating hole 213 to fasten the multiple aperture elastic blades 1 to the aperture support fixing seat 22, ensuring that there is no displacement during adjustment and improving the reliability of the connection. The aperture adjustment guide post mating groove 214 can be connected to the aperture adjustment guide post 312 to mate with the aperture. The rotating disk limiting groove 222 limits the rotation of the aperture rotating disk body 312, improving the accuracy and stability of aperture structure adjustment; the aperture elastic blade rotating protrusion 215 can abut against the multiple aperture elastic blades 1 to prevent the aperture elastic blades 1 from radially shifting during rotation, while reducing the friction with the aperture support cover 21, thereby improving the stability of aperture adjustment of the multiple aperture elastic blades 1 and extending the service life of the multiple aperture elastic blades 1; the aperture cover light transmission hole 216 cooperates with the multiple aperture elastic blades 1 to adjust the light transmission amount to ensure that the light transmission amount meets the requirements.
