[0035] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0036] 1. Variable aperture assembly

[0037] Figure 1 is a schematic diagram of the structure of a variable aperture assembly provided in an embodiment of the present application, referring to Figure 1 As shown, an embodiment of the present disclosure provides a variable aperture assembly, which may include an outer ring 1 , an inner ring 2 , and a plurality of blades 3 .

[0038] The following are the various components of the variable aperture assembly:

[0039] 1. Outer ring 1

[0040] Reference Figure 4As shown, the side of the outer ring 1 away from the blade 3 and the side of the inner ring 2 away from the blade 3 are located in the same plane. The side of the outer ring 1 away from the blade 3 and the side of the inner ring 2 away from the blade 3 are respectively opposite to the camera, and the side of the outer ring 1 away from the blade 3 and the side of the inner ring 2 away from the blade 3 are located in the same plane. Under the premise of ensuring the necessary installation distance between the variable aperture assembly and the camera, the gap distance between the variable aperture assembly and the camera can be reduced, and then the thickness of the lens module 100 can be reduced, so as to facilitate the lightweight design of the electronic device.

[0041] Figure 2 is a cross-sectional schematic diagram of a variable aperture assembly provided in an embodiment of the present application, with reference to Figure 2 As shown, the outer ring 1 may include an outer ring body 11 and an electromagnetic coil 12 .

[0042] 1.1 Outer ring body 11

[0043] The outer ring body 11 has an annular structure, and the annular structure of the outer ring body 11 can be used to accommodate the inner ring 2. The present disclosure does not specifically limit the size of the outer ring body 11, and can be matched and set according to factors such as the size and shape of the aperture area surrounded by the blades of different lens modules 100.

[0044] The outer ring body 11 can be connected to the lens module 100 or the designated area of ​​the electronic device, so as to fix and limit the variable aperture assembly. The present disclosure does not specifically limit the connection relationship between the outer ring body 11 and the designated area, and can adopt a detachable connection method such as threaded fastening connection and snap connection, or a non-detachable connection method such as glue dispensing and welding. The specific setting can be matched according to factors such as the mechanical strength of the connection, the use scenario of the variable aperture assembly, and the type of electronic device.

[0045] 1.2 Electromagnetic coil 12

[0046] The electromagnetic coil 12 is connected to the outer ring body 11. The present disclosure does not specifically limit the connection position between the electromagnetic coil 12 and the outer ring body 11. The connection position can be the outer wall of the outer ring body 11 in the radial direction, or the two side walls of the outer ring body 11 in the axial direction.

[0047] In some embodiments, the electromagnetic coil 12 can be directly connected to the outer wall of the outer ring body 11 in the radial direction. In this case, the outer ring body 11 does not need to be processed accordingly, and the processing technology is relatively simple.

[0048] In some other embodiments, Figure 5 is an exploded schematic diagram of a variable aperture assembly provided in an embodiment of the present application, with reference to Figure 5As shown, the outer ring body 11 may have a second accommodating groove 112, the second accommodating groove 112 is located on the outer wall of the outer ring body 11 in the radial direction or the side wall of the outer ring body 11 in the axial direction, and the electromagnetic coil 12 is located in the second accommodating groove 112 and connected to the second accommodating groove 112. The second accommodating groove 112 may have a certain limiting effect on the electromagnetic coil 12, so as to prevent the electromagnetic coil 12 from sliding with the outer ring body 11 or falling off from the outer ring body 11; at the same time, the provision of the second accommodating groove 112 reduces the volume and mass of the outer ring body 11, and facilitates the lightweight design of the variable aperture assembly.

[0049] In the disclosed embodiment, the electromagnetic coil 12 is prevented from being directly connected to the side wall of the outer ring body 11 in the axial direction, so as to prevent the volume of the electromagnetic coil 12 from increasing the thickness of the outer ring 1 in its axial direction, thereby affecting the overall thickness of the variable aperture assembly.

[0050] At least part of the inner ring 2 is magnetic, and the electromagnetic coil 12 is used to drive the inner ring 2 to rotate. According to the principle of electromagnetic induction, when current passes through the electromagnetic coil 12, a magnetic field can be formed around the electromagnetic coil 12, and the magnetic field generated by the electromagnetic coil 12 interacts with the magnetic area of ​​the inner ring 2, generating a force to make the inner ring 2 rotate relative to the outer ring 1.

[0051] 2. Inner circle 2

[0052] In some embodiments, the inner ring 2 and the outer ring 1 are rotatably connected via a ball groove mechanism. In the radial direction of the inner ring 2, the outer wall of the inner ring 2 is opposite to the inner wall of the outer ring 1, and the ball is located between the outer wall of the inner ring 2 and the inner wall of the outer ring 1. The outer wall of the inner ring 2 and the inner wall of the outer ring 1 respectively have grooves that are adapted to the size and shape of the ball. The ball can rotate in the groove, thereby realizing the rotational connection between the inner ring 2 and the outer ring 1.

[0053] In the disclosed embodiment, the inner ring 2, the outer ring 1 and the balls are assembled similarly to the bearing assembly. The inner ring 2 is tilted to one side, the balls are inserted into the groove between the inner ring 2 and the outer ring 1, and the installation is completed by rotating the inner ring 2. The installation process is simple, convenient and highly reliable.

[0054] The present disclosure does not make any specific limitation on the connection relationship between the inner ring 2 and the outer ring 1. The inner ring 2 and the outer ring 1 can also be rotatably connected via a slider and rail mechanism. One of the inner ring 2 and the outer ring 1 has a slider and the other has a rail groove matched with the slider. The slider is located in the rail groove and can slide in the rail groove, thereby realizing the rotational connection between the inner ring 2 and the outer ring 1.

[0055] Reference Figure 2 As shown, the inner ring 2 may include an inner ring body 21 and a magnetic member 22 .

[0056] 2.1 Inner ring body 21

[0057] The inner ring body 21 has an annular structure, is located in the annular structure of the outer ring body 11, and is rotatably connected to the outer ring body 11. The present disclosure does not specifically limit the size of the inner ring body 21, and can be matched and set according to factors such as the size of the outer ring body 11 and the connection relationship between the inner ring body 21 and the outer ring body 11.

[0058] Figure 6 is a schematic diagram of the structure of another variable aperture assembly provided in an embodiment of the present application, referring to Figure 6 As shown, the inner ring body 21 has a limiting portion 213 , the outer ring body 11 has a limiting groove 113 , the limiting portion 213 is located in the limiting groove 113 , and can move in the limiting groove 113 .

[0059] The limiting part 213 and the limiting groove 113 can replace the first protrusion 211 and the slide groove 31 to play a microscopic role on the blade 3. When the variable aperture assembly is in a non-working state, the limiting part 213 and the limiting groove 113 cooperate with each other to prevent the blade 3 from swinging randomly due to the stress applied by the outside world, and prevent the blade 3 from opening and closing too much and causing damage. At the same time, since the blade 3 has a small thickness and low mechanical strength, the limiting part 213 and the limiting groove 113 can prevent the blade 3 from being deformed or broken due to the contact between the first protrusion 211 and the slide groove 31, which is beneficial to increase the working life of the variable aperture assembly.

[0060] 2.2 Magnetic parts 22

[0061] The magnetic member 22 is connected to the inner ring body 21. The present disclosure does not specifically limit the connection position between the magnetic member 22 and the inner ring body 21. The connection position can be the inner wall of the inner ring body 21 in the radial direction, or the two side walls of the inner ring body 21 in the axial direction.

[0062] In some embodiments, the magnetic member 22 can be directly connected to the inner wall of the inner ring body 21 in the radial direction. In this case, the inner ring body 21 does not need to be processed accordingly, and the processing technology is relatively simple. It should be noted that when the magnetic member 22 is directly connected to the inner wall of the inner ring body 21 in the radial direction, the magnetic member 22 is prevented from blocking the aperture area surrounded by the multiple blades 3.

[0063] In some other embodiments, referring to Figure 5As shown, the inner ring body 21 may have a first receiving groove 212, the first receiving groove 212 is located on the inner wall of the inner ring body 21 in the radial direction or the side wall of the inner ring body 21 in the axial direction, and the magnetic member 22 is located in the first receiving groove 212 and connected to the first receiving groove 212. The first receiving groove 212 may have a certain limiting effect on the magnetic member 22, so as to prevent the magnetic member 22 from sliding with the inner ring body 21 or falling off from the inner ring body 21; at the same time, the provision of the first receiving groove 212 reduces the volume and mass of the inner ring body 21, and facilitates the lightweight design of the variable aperture assembly. In the embodiment disclosed in the present invention, it is avoided that the magnetic member 22 increases the thickness of the inner ring 2 along its axial direction, thereby affecting the overall thickness of the variable aperture assembly.

[0064] The present disclosure does not specifically limit the number and shape of the magnetic parts 22. For example, the magnetic part 22 can be an annular magnetic part 22, and the axis of the annular magnetic part 22 coincides with the axis of the inner ring body 21. The magnetic part 22 can also be a plurality of rectangular magnetic parts 22, and the plurality of rectangular magnetic parts 22 are evenly distributed around the circumference of the axis of the inner ring body 21, which is beneficial for uniform force on the plurality of rectangular magnetic parts 22, thereby enabling the inner ring body 21 to drive the blades 3 to move smoothly.

[0065] The present disclosure does not make any specific limitation on the connection relationship between the magnetic part 22 and the inner ring body 21. A detachable connection method such as threaded fastening connection and snap connection can be adopted, or a non-detachable connection method such as glue dispensing can be adopted. The specific setting can be matched according to factors such as the number, volume, and shape of the magnetic part 22.

[0066] When the electromagnetic coil 12 is powered on, it cooperates with the magnetic part 22 to drive the inner ring 2 to rotate relative to the outer ring 1. According to the principle of electromagnetic induction, when current passes through the electromagnetic coil 12, a magnetic field can be formed around the electromagnetic coil 12. The magnetic field generated by the electromagnetic coil 12 interacts with the magnetic part 22 of the inner ring 2 to generate a force that causes the inner ring 2 to rotate relative to the outer ring 1.

[0067] 3. Blade 3

[0068] The blades 3 are hinged to the outer ring 1, and the blades 3 are slidably connected to the inner ring 2. The rotation of the inner ring 2 relative to the outer ring 1 can drive the ends of multiple blades 3 to synchronously approach or move away from the axis of the inner ring 2, thereby increasing or decreasing the aperture area.

[0069] The present disclosure does not specifically limit the number of blades 3, and can be set according to different requirements of different devices for aperture shape, size and other factors. The more blades 3 there are, the closer the shape of the aperture is to a circle, and the smoother the edge is; the fewer blades 3 there are, the simpler the installation process of the variable aperture assembly is, which is convenient for simplifying the work of the installer.

[0070] In some embodiments, reference Figure 1 As shown, the number of blades 3 is an even number, and two blades 3 separated by one blade 3 are located in the same plane. For example: the number of blades 3 is 6, which are named the first to sixth blades in clockwise order, among which the first, third, and fifth blades can be located in the same plane, that is, the lower surfaces of the first, third, and fifth blades are respectively fitted with the outer ring 1 and the inner ring 2, and the second, fourth, and sixth blades can be located in the same plane, that is, the lower surfaces of the second, fourth, and sixth blades are fitted with the upper surfaces of the first, third, and fifth blades. Such a setting can avoid friction or collision between adjacent blades 3 during movement, and realize the infinite rotation of blades 3.

[0071] In some other embodiments, the number of blades 3 is an odd number, for example, the number of blades 3 is 5, which are named as the first to fifth blades in clockwise order, wherein the first, third and fifth blades can be located in the same plane, that is, the lower surfaces of the first, third and fifth blades are respectively fitted with the outer ring 1 and the inner ring 2, and the second and fourth blades can be located in the same plane, that is, the lower surfaces of the second and fourth blades are fitted with the upper surfaces of the first, third and fifth blades. At this time, it should be noted that the shapes of the first blade and the fifth blade are adapted to ensure that the first blade and the fifth blade can enclose a preset aperture area, and the first blade and the fifth blade will not cause friction or collision during movement.

[0072] 3.1 Connection between blade 3 and inner ring 2

[0073] In some embodiments, Figure 3 is a schematic diagram of the structure of a blade provided in an embodiment of the present application, referring to Figure 2 and Figure 3 As shown, the blade 3 has a slide groove 31 , and the inner ring body 21 has a first protrusion 211 . The first protrusion 211 is located in the slide groove 31 and can slide in the slide groove 31 .

[0074] When the variable aperture assembly is not in operation, the slide groove 31 cooperates with the first protrusion 211 to prevent the blades 3 from swinging randomly due to external stress, and to prevent the blades 3 from opening and closing too much and causing damage.

[0075] The number of the first protrusions 211 is the same as the number of the blades 3 , so as to ensure that the slide groove 31 of each blade 3 cooperates with a second protrusion 111 to achieve a sliding connection between the blade 3 and the outer ring 1 .

[0076] 3.2 Connection between blade 3 and outer ring 1

[0077] In some embodiments, reference Figure 2 and Figure 3As shown, the blade 3 has a through hole 32 , and the outer ring body 11 has a second protrusion 111 . The second protrusion 111 is matched with the through hole 32 . The second protrusion 111 is located in the through hole 32 and is rotatably connected to the blade 3 .

[0078] The number of the second protrusions 111 is the same as the number of the blades 3 , so as to ensure that the through hole 32 of each blade 3 cooperates with one second protrusion 111 to achieve a hinged connection between the blade 3 and the outer ring 1 .

[0079] 3.3 aperture

[0080] The area surrounded by the multiple blades 3 is an aperture area. The aperture has a preset maximum area and a minimum area. The aperture can adjust different aperture areas according to different usage scenarios.

[0081] 3.3.1 Maximum aperture

[0082] In some embodiments, reference Figure 1 and Figure 3 As shown, the slide groove 31 can have a limiting effect on the blade 3, the first protrusion 211 abuts against one end of the slide groove 31, the blade 3 has a first state, and the aperture surrounded by the plurality of blades 3 in the first state can be the maximum aperture;

[0083] In some other embodiments, referring to Figure 6 As shown, the inner ring body 21 has a limiting portion 213, the outer ring body 11 has a limiting groove 113, the limiting portion 213 is located in the limiting groove 113, and can move in the limiting groove 113. The limiting portion 213 abuts against one end of the limiting groove 113, and the blade 3 has a third state. At this time, there is a certain gap between the first protrusion 211 and the end of the slide groove 31, and the aperture surrounded by the multiple blades 3 in the third state can be the maximum aperture.

[0084] 3.3.2 Minimum aperture

[0085] In some embodiments, reference Figure 1 and Figure 3 As shown, the slide groove 31 can limit the blade 3, the first protrusion 211 abuts against one end of the slide groove 31, the blade 3 has a second state, and the aperture surrounded by multiple blades 3 in the second state can be the smallest aperture.

[0086] In some other embodiments, referring to Figure 6As shown, the inner ring body 21 has a limiting portion 213, the outer ring body 11 has a limiting groove 113, the limiting portion 213 is located in the limiting groove 113, and can move in the limiting groove 113. The limiting portion 213 abuts against one end of the limiting groove 113, and the blade 3 has a fourth state. At this time, there is a certain gap between the first protrusion 211 and the end of the slide groove 31, and the aperture surrounded by the multiple blades 3 in the fourth state can be the minimum aperture.
