Description

Technical Field

[0001] This application belongs to the technical field of aperture structures, and particularly relates to an aperture assembly and an electronic device. Background Art

[0002] In order to improve the shooting performance of an electronic device, an aperture assembly with a variable aperture size is provided on the electronic device. Since the aperture size is variable, it is possible to adjust the amount of light entering the camera module, thereby improving the resolution of the camera module and further improving the shooting performance of the electronic device.

[0003] In related technologies, the aperture assembly includes a fixed base, a rotating bracket, and a light-shielding member. A rolling body is provided between the fixed base and the rotating bracket to achieve relative rotation between the fixed base and the rotating bracket. The rotating bracket can drive a plurality of light-shielding members to rotate relative to the fixed base, so that the overlapping area between the plurality of light-shielding members and the light-transmitting area decreases or increases.

[0004] However, the rotating bracket and the fixed base are easily collided by the rolling body to form pits, which easily causes the rotating bracket to rotate eccentrically, thereby reducing the dimming accuracy of the aperture assembly. Summary of the Invention

[0005] The purpose of the embodiments of this application is to provide an aperture assembly and an electronic device, which can solve the technical problem of poor dimming accuracy of the aperture assembly.

[0006] To solve the above technical problem, this application is implemented as follows: This application discloses an aperture assembly, including: A fixed base, the fixed base includes a housing and a first guiding portion, the housing is provided with a light-transmitting area, and the first guiding portion is fixedly connected to the housing; An actuating member, the actuating member is arranged inside the housing; A rotating bracket, the rotating bracket is arranged inside the housing and is movably connected to the actuating member. The rotating bracket includes a turntable body and a second guiding portion, the second guiding portion is fixedly connected to the turntable body, and the actuating member is used to drive the turntable body to rotate relative to the housing around its central axis; the second guiding portion and the first guiding portion overlap along the direction of the central axis of the turntable body, and the first guiding portion and the second guiding portion are guidingly matched along the rotation direction of the turntable body; A plurality of light-shielding members, each light-shielding member is rotatably connected to the fixed base, and each light-shielding member is slidably connected to the rotating bracket. The rotating bracket is used to drive the plurality of light-shielding members to rotate relative to the fixed base, so that the overlapping area between the plurality of light-shielding members and the light-transmitting area decreases or increases.

[0007] The present application discloses an electronic device, including a device main body, a camera module, and the above aperture assembly. The camera module and the aperture assembly are both disposed on the device main body, and the aperture assembly is disposed opposite to the camera assembly for adjusting the light incident amount of the camera module.

[0008] In an embodiment of the present application, the fixed base is provided with a first guiding portion, and the rotating bracket is provided with a second guiding portion. The second guiding portion and the first guiding portion are lapped along the central axis direction of the turntable main body of the rotating bracket, and the first guiding portion and the second guiding portion are in guiding cooperation along the rotation direction of the turntable main body. In this solution, the rolling body guiding between the fixed base and the rotating bracket is cancelled, and the mutually cooperating guiding portions are respectively provided on the fixed base and the rotating bracket. At this time, when the rotating bracket is driven by the actuating member to rotate, the second guiding portion contacts the first guiding portion, so as to ensure that the rotating bracket always remains in the same rotation plane, and further can guide the rotation direction of the rotating bracket. Compared with the aperture assembly in the related art, for the aperture assembly disclosed in the present application, the guiding portions are respectively provided on the fixed base and the rotating bracket to achieve the guiding function, so the rolling body is cancelled, thereby avoiding the generation of pits between the rotating bracket and the fixed base, thus ensuring the guiding accuracy of the rotating bracket, avoiding the risk of eccentric rotation of the rotating bracket, further improving the light adjustment accuracy of the aperture assembly, and thus improving the reliability of the aperture assembly.

Detailed implementation manners

[0011] The following will clearly describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0012] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0013] The following will, with reference to the accompanying drawings, illustrate in detail the aperture assembly and the electronic device provided in the embodiments of the present application through specific embodiments and their application scenarios.

[0014] Please refer to Figures 1 to 15 , an aperture assembly 100 is disclosed in the embodiments of the present application. The disclosed aperture assembly 100 includes a fixed base 110, an actuating part 120, a rotating bracket 130, and a light - shielding part 140.

[0015] The fixed base 110 includes a housing 111 and a first guiding portion 112. The housing 111 provides an installation base for other components of the aperture assembly 100. The housing 111 is provided with a light-transmitting area 1101. Here, the light-transmitting area 1101 refers to an area that can transmit light. At this time, light can pass through the housing 111 through the light-transmitting area 1101. The light-transmitting area 1101 here can be understood as the aperture. Optionally, the light-transmitting area 1101 can be a light-transmitting hole, and of course it can also be a solid area that can transmit light. The first guiding portion 112 is fixedly connected to the housing 111. At this time, the housing 111 and the first guiding portion 112 form an integral structure. The first guiding portion 112 here can be connected to the housing 111 as a whole through components such as an adhesive layer and screws. Or, the first guiding portion 112 and the housing 111 can be integrally processed or cast. The specific forming method of the first guiding portion 112 and the housing 111 is not limited here.

[0016] The actuating member 120 is disposed inside the housing 111. At this time, the housing 111 can have a receiving space, and the actuating member 120 can be disposed in the receiving space of the housing 111. The above-mentioned first guiding portion 112 is also located in the receiving space of the housing 111.

[0017] The rotating bracket 130 is disposed inside the housing 111 and is movably connected to the actuating member 120. The actuating member 120 is used to provide power for the rotating bracket 130 to rotate relative to the housing 111. At this time, the rotating bracket 130 is also located in the receiving space of the housing 111. The actuating member 120 here is used to drive the rotating bracket 130 to rotate inside the housing 111. The rotating bracket 130 includes a turntable body 131 and a second guiding portion 132. The second guiding portion 132 is fixedly connected to the turntable body 131. At this time, the turntable body 131 and the second guiding portion 132 form an integral structure. The second guiding portion 132 here can be connected to the turntable body 131 as a whole through components such as an adhesive layer and screws. Or, the second guiding portion 132 and the turntable body 131 can be integrally processed or cast. The specific forming method of the second guiding portion 132 and the turntable body 131 is not limited here.

[0018] In order to prevent the rotating bracket 130 from blocking the light-transmitting area 1101, the rotating bracket 130 can be made of a transparent material, such as transparent resin and transparent glass. Or, the rotating bracket 130 can be provided with a through hole, and the through hole is disposed opposite to the light-transmitting area 1101, so as to prevent the rotating bracket 130 from blocking the light-transmitting area 1101. Of course, it can also be understood that the rotating bracket 130 is a ring structure, and the above-mentioned through hole is the inner ring area of the ring structure.

[0019] The actuator 120 is used to drive the turntable body 131 to rotate relative to the housing 111 about its central axis. At this time, since the turntable body 131 is fixedly connected to the second guiding portion 132, the turntable body 131 also drives the second guiding portion 132 to rotate about the central axis of the turntable body 131 during rotation. The central axis here is the axis passing through the physical center of the turntable body 131. The second guiding portion 132 and the first guiding portion 112 overlap in the direction of the central axis of the turntable body 131. Here, it can be understood that the second guiding portion 132 overlaps on the first guiding portion 112, and the second guiding portion 132 is in contact with the first guiding portion 112. The first guiding portion 112 and the second guiding portion 132 are guidingly engaged along the rotation direction of the turntable body 131.

[0020] At this time, it can be understood that the first guiding portion 112 has a first contact surface 112a, the second guiding portion 132 has a second contact surface 132a, and the first guiding portion 112 and the second guiding portion 132 overlap through the first contact surface 112a and the second contact surface 132a. At this time, an arc-shaped guiding section is formed by the overlapping contact between the first contact surface 112a and the second contact surface 132a, and the central axis of this arc-shaped guiding section coincides with the central axis of the turntable body 131. Or, it can also be understood that the first guiding portion 112 and the second guiding portion 132 are formed by rotating a reference line along the central axis of the turntable body 131 by a certain angle or rotating one week. The reference line here can be a curve or a straight line. At this time, the central axes of the first guiding portion 112, the second guiding portion 132, and the turntable body 131 coincide. Similarly, it can be that the first contact surface 112a and the second contact surface 132a are formed by rotating a reference line along the central axis of the turntable body 131 by a certain angle or rotating one week. At this time, the central axes of the first contact surface 112a, the second contact surface 132a, and the turntable body 131 coincide.

[0021] In this application, the fixed base 110 and the rotating bracket 130 are slidingly guidingly engaged through the first guiding portion 112 and the second guiding portion 132. During the rotation of the rotating bracket 130, the second guiding portion 132 is in contact with the first guiding portion 112. Since the central axes of the first guiding portion 112, the second guiding portion 132, and the rotating bracket 130 coincide, the rotating bracket 130 is always maintained in the same rotation plane, so that the rotating bracket 130 can rotate stably relative to the fixed base 110.

[0022] The number of the light-shielding members 140 is plural, and each light-shielding member 140 is rotatably connected to the fixed base 110. Here, the light-shielding member 140 can be rotatably connected to the fixed base 110 through the rotating shaft 1103. The rotating shaft 1103 can be arranged on the housing 111, or can also be arranged on the first guiding portion 112. There is no limitation on the specific connection position between the light-shielding member 140 and the fixed base 110. Each light-shielding member 140 is slidably connected to the rotating bracket 130. The rotating bracket 130 is used to drive the plural light-shielding members 140 to rotate relative to the fixed base 110, so that the overlapping area between the plural light-shielding members 140 and the light-transmitting area 1101 is reduced or increased. Optionally, a driving chute 141 can be arranged on one of the light-shielding member 140 and the rotating bracket 130, and a driving protrusion 134 can be arranged on the other. At least a part of the driving protrusion 134 is arranged in the driving chute 141. At this time, through the sliding fit between the driving protrusion 134 and the driving chute 141, the driving of the light-shielding member 140 by the rotating bracket 130 can be realized.

[0023] In a scheme, a driving chute 141 can be arranged on the light-shielding member 140, and a driving protrusion 134 can be arranged on the turntable body 131. Or, the driving protrusion 134 can also be arranged on the second guiding portion 132. There is no limitation on the specific position of the driving protrusion 134. Of course, other sliding connection methods can also be adopted between the light-shielding member 140 and the rotating bracket 130, and there is no limitation here.

[0024] In the specific operation process, when the rotating bracket 130 rotates in the first direction, the rotating bracket 130 drives the light-shielding member 140 to rotate in the direction towards the center of the light-transmitting area 1101, so that the overlapping area between the light-shielding member 140 and the light-transmitting area 1101 is increased. At this time, the area of the light-shielding member 140 covering the light-transmitting area 1101 is larger, so the aperture size is smaller and the light input amount is reduced. When the rotating bracket 130 rotates in the second direction opposite to the first direction, the rotating bracket 130 drives the light-shielding member 140 to rotate in the direction away from the center of the light-transmitting area 1101, so that the overlapping area between the light-shielding member 140 and the light-transmitting area 1101 is reduced. At this time, the area of the light-shielding member 140 covering the light-transmitting area 1101 is smaller, so the aperture size is larger and the light input amount is increased.

[0025] In the embodiments disclosed in the present application, when the rotating bracket 130 is driven to rotate by the actuator 120, the second guiding portion 132 contacts the first guiding portion 112, so as to ensure that the rotating bracket 130 always remains in the same rotation plane, and further can guide the rotation direction of the rotating bracket 130, thereby realizing the guiding function. Therefore, in the present application, the fixed base 110 and the rotating bracket 130 realize the guiding function through the first guiding portion 112 and the second guiding portion 132, so that it is not necessary to guide through the rolling elements in the related art. Therefore, the rolling elements are cancelled in the aperture assembly of the present application, and the guiding structure composed of the first guiding portion 112 and the second guiding portion 132 is adopted for guiding, thereby avoiding the risk of pits generated between the rotating bracket 130 and the fixed base 110. Therefore, the guiding accuracy of the rotating bracket 130 is improved, and the risk of eccentric rotation of the rotating bracket 130 is avoided, so that the aperture always coincides with the optical axis center, and the aperture consistency is good, thereby improving the dimming accuracy of the aperture assembly 100. In addition, the fixed base 110 and the rotating bracket 130 are rotationally connected through the first guiding portion 112 and the second guiding portion 132. The first guiding portion 112 and the second guiding portion 132 have a larger area compared with the rolling elements. Therefore, the contact area between the fixed base 110 and the rotating bracket 130 is larger, so that the impact force can be effectively dispersed, and further the problems such as pits generated by the impact are optimized. Therefore, the reliability of the aperture assembly 100 is effectively improved.

[0026] In addition, compared with the solution of the related art, a plurality of rolling elements need to be installed between the fixed base 110 and the rotating bracket 130 in the related art. Therefore, there are more assembly parts, so that the assembly difficulty is greater, the structure is more complex, and the cost is higher. In the embodiments disclosed in the present application, the fixed base 110 and the rotating bracket 130 are guided by two guiding portions distributed thereon. Therefore, it is not necessary to provide ball bearings, thereby simplifying the assembly structure of the aperture assembly 100, reducing the assembly difficulty, making the structure of the aperture assembly 100 simple, and the cost is also lower.

[0027] In the above solution, the actuator 120 can be an electromagnetic drive structure. For example, the actuator 120 can include a magnet and an energized coil. One of the magnet and the energized coil is arranged on the housing 111, and the other is arranged on the turntable body 131. When the energized coil is energized, a force is generated between the magnet and the energized coil, so as to drive the rotating bracket 130 to rotate.

[0028] In one solution, the above-mentioned first contact surface 112a and second contact surface 132a can both be inclined arc-shaped planes, which can also be understood that the first contact surface 112a and the second contact surface 132a are both conical surfaces.

[0029] Alternatively, in another solution, one of the first contact surface 112a and the second contact surface 132a can be an inclined arc plane, and the other can be an arc convex surface. Here, the arc convex surface can be understood as a spherical surface or a toroidal surface. At this time, the arc convex surface is in contact with the arc plane.

[0030] Or, one of the first contact surface 112a and the second contact surface 132a can be an arc concave surface, and the other is an arc convex surface. At this time, the arc convex surface is exactly fitted in the arc concave surface.

[0031] In order to reduce the friction between the first guiding portion 112 and the second guiding portion 132, in another alternative embodiment, both the first contact surface 112a and the second contact surface 132a can be arc convex surfaces. In this solution, the contact area between the two arc convex surfaces is an arc line segment. At this time, while ensuring the guiding effect, the contact area between the first guiding portion 112 and the second guiding portion 132 is further reduced, so that the rotation of the rotating bracket 130 is smoother.

[0032] In the above solutions, the first guiding portion 112 and the second guiding portion 132 can be annular structures, that is to say, the area where the first guiding portion 112 and the second guiding portion 132 are in contact with each other is a circular area or a toroidal area.

[0033] In another alternative solution, the number of the first guiding portions 112 can be multiple, and the multiple first guiding portions 112 can be arranged at intervals along the circumferential direction of the light-transmitting area 1101. The number of the second guiding portions 132 is multiple, and the multiple second guiding portions 132 can be arranged at intervals along the outer peripheral surface of the turntable body 131. The first guiding portions 112 and the second guiding portions 132 are arranged in one-to-one correspondence.

[0034] In this solution, the multiple first guiding portions 112 on the fixed base 110 and the multiple second guiding portions 132 on the rotating bracket 130 are in one-to-one lap joint to form multiple arc guiding segments. The multiple arc guiding segments can guide the rotation direction of the turntable body 131 along the circumferential direction of the turntable body 131. Therefore, the circumferential supporting force of the turntable body 131 is relatively uniform, avoiding the risk of unilateral inclination. Therefore, the rotation stability of the rotating bracket 130 is further improved. In addition, compared with the solution where the first guiding portion 112 and the second guiding portion 132 are integrally an annular structure, the multi-segment guiding structure can avoid the risk of interference with other components, and further optimizes the structural layout of the aperture assembly 100.

[0035] In another solution, the rotating bracket 130 may further include a limiting convex portion 133. The limiting convex portion 133 may be disposed on the outer peripheral surface of the turntable body 131 and located between any two second guiding portions 132. A limiting groove 115 may be defined between two adjacent first guiding portions 112. At least a part of the limiting convex portion 133 may be located in the limiting groove 115, and the limiting convex portion 133 may slide in the limiting groove 115 along the rotation direction of the turntable body 131.

[0036] In this solution, any two adjacent second guiding portions 132 may be understood as two side walls of the limiting groove 115. The limiting groove 115 can limit the rotation angle of the rotating bracket 130, thereby avoiding the risk of damage to the light-shielding member 140 caused by excessive rotation of the rotating bracket 130.

[0037] Further, the first guiding portion 112 may include a first support protrusion 1121, a sliding fit section 1122, and a second support protrusion 1123 arranged circumferentially along the light-transmitting area 1101. The second guiding portion 132 may overlap with the sliding fit section 1122 in the direction of the central axis of the turntable body 131. At this time, the sliding fit section 1122 and the second guiding portion 132 are in guiding cooperation along the rotation direction of the turntable body 131. At this time, the area in guiding cooperation with the second guiding portion 132 is the sliding fit section 1122 on the first guiding portion 112. The first support protrusion 1121 and the second support protrusion 1123 may be respectively rotatably connected to a corresponding light-shielding member 140.

[0038] In this solution, the light-shielding member 140 is disposed on the support protrusions on both sides of the first guiding portion 112, thereby simplifying the connection structure between the light-shielding member 140 and the fixed base 110, and further making the structure of the aperture assembly 100 simpler.

[0039] Optionally, a rotating shaft 1103 may be provided on both the first support protrusion 1112a and the second support protrusion 1112c, and the light-shielding member 140 may be rotatably connected through the rotating shaft 1103.

[0040] In the above solution, the actuator 120 is provided with a circuit board, and the energized coil patch is soldered on the circuit board. The circuit board is electrically connected to the circuit, and the circuit board can control the energized coil and supply electrical energy to the energized coil. However, the energized coil is disposed on the surface of the circuit board and is exposed, so the energized coil is easily damaged during the assembly process. In addition, a relatively large gap needs to be reserved between the rotating bracket 130 and the circuit board to accommodate the energized coil, so the overall thickness dimension of the aperture assembly 100 is likely to be large.

[0041] Based on this, in another alternative solution, the actuator 120 may include a magnet group 121 and an energized circuit structure 122. The energized circuit structure 122 may include a circuit substrate 1221 and a plurality of coils 1222. Here, the circuit substrate 1221 can be understood as a circuit board. The plurality of coils 1222 may be buried in the circuit substrate 1221 at intervals. At this time, the coils 1222 are buried in the circuit substrate 1221, that is to say, the coils 1222 do not protrude from the circuit substrate 1221, and the coils 1222 and the circuit substrate 1221 form an integral structure. The magnet group 121 may be fixed to the rotating bracket 130. Optionally, the magnet group 121 may be provided on the turntable body 131. If the installation space permits, the magnet group 121 may also be provided on the second guiding portion 132. Or, the magnet group 121 may also be provided on the above-mentioned limiting convex portion 133. The circuit substrate 1221 may be fixed in the housing 111, and the circuit substrate 1221 and the rotating bracket 130 may be arranged along the central axis direction of the turntable body 131. Each coil 1222 may correspond to at least one magnet in the magnet group 121. When the energized circuit structure 122 is energized, the magnet group 121 drives the turntable body 131 to rotate.

[0042] In this solution, the coils 1222 are buried in the circuit substrate 1221, thus avoiding the risk of the exposed coils 1222 being stressed and broken, thereby improving the safety and reliability of the coils 1222. In addition, since the coils 1222 are buried in the circuit substrate 1221, there is no need to reserve an installation position for the coils 1222 between the rotating bracket 130 and the circuit substrate 1221. Therefore, it is beneficial to reduce the stacking thickness of the rotating bracket 130 and the circuit substrate 1221, and further beneficial to reduce the thickness of the aperture assembly 100, thereby facilitating the development of the aperture assembly 100 towards being thinner and lighter.

[0043] Optionally, the coils 1222 may be printed on the circuit substrate 1221 by printing. Or, embedding holes may be formed on the circuit substrate 1221. The coils 1222 are placed in the embedding holes, and then glue is filled to bury the coils 1222 in the circuit substrate 1221. Of course, the coils 1222 may also be buried in the circuit substrate 1221 by other means, which is not limited herein.

[0044] Furthermore, the housing 111 may be provided with a magnetic member 150, and the magnetic member 150 may be magnetically coupled with at least one magnet in the magnet group 121. In this solution, the fixed base 110 and the rotating bracket 130 are attracted by the magnetic member 150 and the magnet, so that the first guiding portion 112 and the second guiding portion 132 are closely combined, so that it is not easy for the rotating bracket 130 to generate a biasing force, thereby further improving the stability of the aperture assembly 100.

[0045] Optionally, the magnetic member 150 may be a magnet. Of course, the magnetic member 150 may also be an electromagnet. The specific structure of the magnetic member 150 is not limited in this article.

[0046] In another alternative solution, the magnetic member 150 may be embedded in the housing 111. In this solution, the magnetic member 150 is embedded in the housing 111, thereby avoiding the risk of interference between the magnetic member 150 and the actuating member 120 and the rotating bracket 130. In addition, it is also beneficial to further reduce the volume of the aperture assembly 100.

[0047] In another alternative solution, the circuit board 1221 may be stacked with the turntable body 131. The circuit board 1221 may be in an annular plate-like structure. At this time, the inner ring area of the circuit board 1221 is opposite to the light-transmitting area 1101, thereby avoiding the occlusion of the light-transmitting area 1101. An avoidance notch 1221a is provided at the outer edge of the circuit board 1221, and the avoidance notch 1221a may be disposed opposite to the first guiding portion 112.

[0048] In this solution, when the outer diameter of the circuit board 1221 is the same as the inner diameter radius of the inner wall of the housing 111, the avoidance notch 1221a can avoid the first guiding portion 112, avoiding the risk of interference between the circuit board 1221 and the first guiding portion 112. In addition, the circuit board 1221 avoiding the first guiding portion 112 can make the outer contour of the circuit board 1221 match the contour of the receiving groove 1110, so that the circuit board 1221 can be clamped in the receiving space of the housing 111, thereby improving the connection strength between the circuit board 1221 and the base body 111 and further improving the assembly reliability of the aperture assembly 100.

[0049] In another alternative solution, a plurality of mounting grooves 1301 may be provided on one side of the rotating bracket 130 facing the circuit board 1221. At least one magnet may be installed in each mounting groove 1301, and the mounting grooves 1301 may be located between two adjacent second guiding portions 132. This solution can further reduce the stacking thickness between the magnet and the rotating bracket 130, and is therefore beneficial to further reducing the thickness of the aperture assembly 100.

[0050] Optionally, the mounting groove 1301 may be provided on one side of the limiting convex portion 133 facing the circuit board 1221. The specific position where the mounting groove 1301 is provided may be flexibly set and is not limited in this article.

[0051] In an alternative embodiment, the housing 111 may include a base body 1111 and an end cap 1112. The base body 1111 may be provided with a receiving groove 1102, and the end cap 1112 may block the opening of the receiving groove 1102. The rotating bracket 130, the actuating member 120, and the light-shielding member 140 may all be located within the receiving groove 1102. A first through hole 1101a may be formed in the bottom of the receiving groove 1102, and a second through hole 1101b may be formed in the end cap 1112. The first through hole 1101a and the second through hole 1101b may be disposed opposite to each other to form a light-transmitting area 1101. The first guiding portion 112 may be provided on the inner sidewall of the receiving groove 1102.

[0052] In this solution, both the base body 1111 and the end cap 1112 are provided with through holes communicating with the receiving space, so that a light-transmitting area 1101 can be formed, and further the structure of the housing 111 is simpler and the cost is lower.

[0053] In the above solution, a plurality of first guiding portions 112 are arranged at intervals along the circumferential direction of the base body 1111 on the sidewall of the receiving groove 1102. At this time, the outer diameter of the circuit board 1221 may be equal to the inner diameter of the receiving groove 1102. An outward convex portion is formed between two adjacent avoidance notches 1221a on the circuit board 1221. Here, the outward convex portion is the part of the edge of the circuit board 1221 that is not cut off. At this time, the outward convex portion can be clamped between the limiting grooves 115 formed by any two first guiding portions 112. Therefore, it is more beneficial to improve the assembly reliability of the aperture assembly.

[0054] In an alternative embodiment, the base body 1111 may include a cylindrical portion 1111a and a bottom plate 1111b. The bottom plate 1111b may be located within the cylindrical portion 1111a and may enclose the receiving groove 1102 with the cylindrical portion 1111a. The bottom plate 1111b may be provided with a first through hole 1101a, and the first guiding portion 112 may be provided on the inner surface of the cylindrical portion 1111a. In this solution, the structure of the base body 1111 is simple, so the manufacturing difficulty and manufacturing cost of the aperture assembly 100 are further reduced.

[0055] Optionally, the above magnetic member 150 may be embedded in the bottom plate 1111b.

[0056] The above end cap 1112 may be a flat plate structure, that is, the flat plate directly blocks the opening of the receiving groove 1102. Or, as Figure 4 shown, the end cap 1112 may also be a cylindrical structure, and at least a part of the end cap 1112 may be sleeved on the base body 1111. The specific structure of the end cap 1112 is not limited herein.

[0057] In an alternative solution, the fixed base 110 may further include a driving chip 113 and electrical connection pins 114. Both the electrical connection pins 114 and the driving chip 113 may be embedded in the housing 111. Specifically, both the electrical connection pins 114 and the driving chip 113 may be embedded in the base body 1111. The electrical connection pins 114 are electrically connected to the actuating member 120 through the driving chip 113. Here, the electrical connection pins 114 are used to electrically connect to the device body of the electronic device. In this solution, the driving chip 113 and the electrical connection pins 114 are embedded in the base body 1111, thereby avoiding the risk of accidentally colliding with the electrical connection pins 114 and the driving chip 113 during the assembly process and causing damage to the driving chip 113 and the electrical connection pins 114. Therefore, the reliability and safety of the aperture assembly 100 are further improved.

[0058] Optionally, the driving chip 113 and the electrical connection pins 114 may be embedded in the housing 111 by an integrally injection molding process. Alternatively, embedding holes may be formed on the housing 111. The driving chip 113 and the electrical connection pins 114 are placed in the embedding holes, and then glue is filled. After the glue is cured, the driving chip 113 and the electrical connection pins 114 are embedded in the housing 111.

[0059] In an alternative solution, both the electrical connection pins 114 and the driving chip 113 may be embedded on the bottom plate 1111b. Of course, the electrical connection pins 114 and the driving chip 113 may also be embedded in other positions of the housing 111, which is not limited herein.
