Abstract
Description
Technical Field
[0001] This application relates to the field of electronic device manufacturing technology, and in particular to a lens mounting bracket, a reflective assembly, a light-transmitting assembly, a photosensitive structure, a camera module, and an electronic device. Background Technology
[0002] With the development of electronic technology, electronic devices have become indispensable tools in people's daily work and life. The camera function is one of the more common functions of many electronic devices, implemented by the camera module within the device.
[0003] Some camera modules include a lens, a reflector, and a photosensitive structure. The reflector's function is to reflect light transmitted from the lens to the photosensitive structure. The reflector includes a mirror and a lens mount; the mirror is typically glued to the surface of the mirror mount.
[0004] Camera modules are relatively precise optical systems, and the accuracy of the reflector's surface shape has a significant impact on the image quality. Temperature fluctuations, such as the increased temperature caused by heat from electronic devices, can cause the reflective components to expand. Different materials used for the reflector and lens mount will result in different degrees of expansion, leading to reflector deformation. This deformation alters the reflector's surface shape, thus affecting image quality. Summary of the Invention
[0005] This application provides a lens mounting bracket, a reflective assembly, a light-transmitting assembly, a photosensitive structure, a camera module, and an electronic device, which can overcome the problems in related technologies. The technical solution is as follows:
[0006] In a first aspect, embodiments of this application provide a lens mounting bracket, which includes a floating bracket and a fixed bracket. The floating bracket includes a lens mounting portion and a flexible connecting portion, which connects the lens mounting portion and the fixed bracket, allowing the lens mounting portion to move relative to the fixed bracket. The lens mounting portion is used to mount a lens.
[0007] Based on the above characteristics, a reflector is mounted using a lens mounting section of a floating bracket. This lens mounting section is connected to a fixed bracket via a flexible connector, allowing it to float relative to the fixed bracket and move. When temperature changes cause changes in the volume of the fixed bracket, the flexible connector deforms accordingly, protecting the reflector mounted on the lens mounting section from the stretching and compression effects caused by these changes. This reduces or eliminates the impact of temperature variations on the reflector's surface shape, thus improving the imaging quality of the camera module.
[0008] In some examples, the flexible connection is connected to at least two opposite sides of the lens mounting portion, which can make the lens mounting portion more stable. The flexible connection provides support from the opposite sides of the lens mounting portion, making the lens mounting portion more stable. During the process of deformation of the flexible connection portion caused by changes in the volume of the fixed bracket, the flexible connection portion generates a reverse force on the lens mounting portion, making the force on the lens mounting portion more balanced, making the lens mounting portion more stable, and improving the imaging quality of the camera module.
[0009] In some examples, each side of the lens mounting portion connected to the flexible connection portion has two connections to the flexible connection portion, meaning that one side of the lens mounting portion has two connection points with the flexible connection portion.
[0010] Based on the above characteristics, by increasing the connection points, the rotation of the lens mounting part can be suppressed, thereby improving the stability of the lens mounting part and further reducing the impact of temperature changes on the reflector.
[0011] In some examples, the flexible connector is arranged around the lens mounting portion, so that each side of the lens mounting portion can be connected to the flexible connector, and the lens mounting portion can be constrained by the flexible connector in multiple directions, thereby making it more stable.
[0012] In some examples, the flexible connection is arranged symmetrically with respect to the lens mounting portion, wherein the symmetry can be any of the following: axial symmetry, surface symmetry, rotational symmetry, and central symmetry.
[0013] Based on the above characteristics, the symmetrically arranged flexible connecting parts exert a more symmetrical force on the lens mounting part, which can make the lens mounting part more stable.
[0014] In other examples, the flexible connection includes multiple elastic elements, each connected to both the lens mounting portion and the fixing bracket. The elastic deformation of these multiple elastic elements compensates for dimensional changes in the fixing bracket caused by temperature variations, thus preventing the lens mounting portion from being directly stretched or compressed by the fixing bracket. When the temperature returns to its pre-change state, the elastic elements can recover under their own elastic force.
[0015] In other examples, the flexible connection includes a fixing part and a plurality of elastic arms, the fixing part being connected to the fixing bracket, and a first end of the elastic arm being connected to the lens mounting part and a second end being connected to the fixing part.
[0016] Based on the above characteristics, during the expansion of the fixed bracket, the fixed bracket pulls the elastic arm away from the lens mounting part, causing the elastic arm to deform; during the contraction of the fixed bracket, the fixed bracket compresses the elastic arm towards the lens mounting part, causing the elastic arm to deform. The multiple elastic arms are structurally independent, facilitating individual design of their structure or distribution, resulting in a more balanced force on the lens mounting part and greater stability.
[0017] In some examples, at least a portion of the resilient arm extends along the edge of the lens mounting portion. The extension of the resilient arm, or a portion thereof, along the edge of the lens mounting portion can mean that, within the suitable operating temperature range of the electronic device, there exists at least one temperature such that the resilient arm, or a portion thereof, is parallel to the edge of the lens mounting portion. By extending at least a portion of the resilient arm along the edge of the lens mounting portion, it is advantageous to reduce the space occupied by the resilient arm, thereby leaving more space for the lens mounting portion and facilitating the placement of larger reflectors.
[0018] In some examples, the elastic arm includes a first segment and a second segment, one end of the first segment and one end of the second segment are connected, the other end of the first segment is connected to the lens mounting portion, the other end of the second segment is connected to the fixing portion, the first segment extends along one of two adjacent sides of the lens mounting portion, and the second segment extends along the other of two adjacent sides of the lens mounting portion.
[0019] Based on the above features, the elastic arm can compensate for the dimensional changes of the fixed bracket in multiple directions, reduce the impact of the volume change of the fixed bracket on the lens mounting part, and thus reduce the impact on the reflector.
[0020] In some examples, the second end of the elastic arm is partially connected.
[0021] Based on the above characteristics, when the volume of the fixed bracket changes and the elastic arm deforms, the elastic arm connected to the second end is subjected to the same or similar force from the fixed bracket, and the resulting deformation is also the same or similar, which is beneficial to improving the stability of the lens mounting part.
[0022] In some examples, the elastic arm has a notch, and the cross-sectional area of the elastic arm within the notch is smaller than the cross-sectional area outside the notch. Providing a notch in the elastic arm reduces its stiffness, making it more susceptible to deformation as the volume of the fixed support changes.
[0023] In some examples, the fixing part includes a frame, and the plurality of elastic arms and the lens mounting part are all located inside the frame. The frame connects the plurality of elastic arms into one unit, which makes the overall structure of the floating bracket more stable and less prone to deformation during manufacturing.
[0024] In other examples, the fixing part includes a plurality of sub-fixing parts, each of which is connected to the first end of at least one elastic arm.
[0025] Based on the above characteristics, connecting the elastic arm and the fixed bracket using multiple independent sub-fixing parts can reduce the stress on the fixing part. Taking the expansion of the fixed bracket as an example, the fixed bracket exerts a tensile force on the fixing part in a direction away from the lens mounting part. Since each sub-fixing part is located at a different position on the fixed bracket, the direction of the tensile force on each sub-fixing part is also different. The multiple sub-fixing parts are independent of each other and not directly connected. Each sub-fixing part can move independently as the fixed bracket expands, without mutually restricting each other and creating significant stress.
[0026] In some examples, the fixing part is embedded in the fixed bracket, which can make the connection between the floating bracket and the fixed bracket more secure and prevent the floating bracket from loosening.
[0027] As an example, the fixed bracket includes a base plate with a receiving groove, and the floating bracket is located in the receiving groove and connected to the side wall of the receiving groove. Arranging the floating bracket in the receiving groove can reduce the size of the lens mounting bracket, which is beneficial to reducing the space occupied by the reflective components inside the electronic device.
[0028] As an example, the first surface of the lens mounting portion is used to mount a lens, and the second surface of the lens mounting portion has a gap with the fixing bracket, the second surface being the surface opposite to the first surface.
[0029] Based on the above characteristics, the gap can prevent the second surface of the lens mounting part from directly contacting the fixing bracket. As the volume of the fixing bracket increases, the side of the fixing bracket facing the second surface will not exert an outward thrust on the lens mounting part when it expands outward, thus making the lens mounting part more stable.
[0030] In some examples, the lens mounting bracket further includes a buffer pad located on the second surface of the lens mounting portion. The buffer pad can support the lens mounting portion and prevent the flexible connection portion from undergoing plastic deformation that cannot be restored.
[0031] In some examples, the lens mount satisfies at least one of the following:
[0032] The floating support is a metal component, which includes pure metal components and alloy components;
[0033] The fixed bracket is an injection molded part.
[0034] Based on the above characteristics, when manufacturing a lens mount, the fixing part of the floating bracket can be placed into the cavity of the mold used to form the fixing bracket. During the forming process of the fixing bracket, the fixing bracket is wrapped around the fixing part. That is, the lens mount can be formed by insert molding, which is convenient for processing, and the floating bracket and the fixing bracket are tightly connected.
[0035] Secondly, embodiments of this application also provide a reflective assembly, the reflective assembly including a reflector and any of the lens mounting brackets described in the first aspect, the reflector being connected to the lens mounting portion.
[0036] Based on the above characteristics, a reflector is mounted on a lens mounting section, which is connected to a fixed bracket via a flexible connector. This allows the reflector to float relative to the fixed bracket, enabling it to move with the lens mounting section. During temperature changes that cause volume changes in the fixed bracket, the flexible connector, with its low stiffness, deforms along with the volume changes of both the fixed bracket and the reflector. This compensates for the relative deformation of the fixed bracket and the reflector, protecting the reflector from the stretching and compression effects caused by the volume changes of the fixed bracket. This reduces or eliminates the impact of temperature changes on the reflector's surface shape, thus improving the imaging quality of the camera module.
[0037] Thirdly, embodiments of this application also provide a light-transmitting component, which includes a light-transmitting element and any of the lens mounting brackets described in the first aspect, wherein the light-transmitting element is connected to the lens mounting portion.
[0038] A light-transmitting component refers to an optical device that allows light to pass through, such as a lens or optical film. Optical films can include filters and polarizers. By mounting the light-transmitting component on the lens mounting section, the component is placed in a floating state, which reduces or avoids the influence of temperature changes on its shape, thus improving the stability and accuracy of the optical system.
[0039] Fourthly, embodiments of this application also provide a photosensitive structure, which includes a circuit board, a photosensitive chip, and a light-transmitting component as described in the third aspect. The photosensitive chip is connected to the circuit board, and the light-transmitting element of the light-transmitting component is arranged opposite to the photosensitive area of the photosensitive chip. The lens mounting bracket in the light-transmitting component can reduce or avoid the influence of temperature changes on the shape of the light-transmitting element, which is beneficial to reducing the influence of temperature on the photosensitive structure and improving the stability and accuracy of the photosensitive structure.
[0040] Fifthly, embodiments of this application also provide a camera module, the camera module including a lens, a photosensitive structure and a reflective component as described in the second aspect, the reflective component being located on the image side of the lens to reflect light transmitted by the lens to the photosensitive structure.
[0041] Based on the above characteristics, since the reflector in the reflective assembly is less affected by the fixed bracket when the temperature changes, the surface shape of the reflector is less affected by the temperature, which is beneficial to improving the imaging quality of the camera module and avoiding the impact of temperature changes on the imaging quality.
[0042] Sixthly, embodiments of this application also provide an electronic device, which includes a camera module as described in the third aspect. Attached Figure Description

[0085] Figure 1 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. The electronic device can be a device with a shooting function, and can be, but is not limited to, a mobile phone, smartwatch, smart bracelet, tablet computer, PDA, laptop computer, monitor, dashcam, or camera. This embodiment uses a mobile phone as an example. Figure 1 As shown, the electronic device includes a camera module 1000.
[0086] Figure 2 This is a schematic diagram of the structure of a camera module provided in an embodiment of this application. Figure 2 As shown, the camera module 1000 includes a lens 100, a photosensitive structure 200, and a reflector 300. The reflector 300 is located on the image side of the lens 100 to reflect the light transmitted through the lens 100 to the photosensitive structure 200.
[0087] Figure 3 This is a schematic diagram of the internal structure of a reflective component. (Example) Figure 3 As shown, the reflector assembly 300 may include a reflector 10 and a lens mounting bracket 20. The reflector 10 is connected to the lens mounting bracket 20, for example, the reflector 10 is bonded to the lens mounting bracket 20.
[0088] Changes in air temperature or heat generated during the operation of electronic devices can cause temperature changes in the reflective assembly 300. These temperature changes can cause the reflective assembly 300 to expand or contract. Figure 4 This is a schematic diagram showing the volume change of the reflective component due to temperature. Figure 4 The image shows the state of the reflective assembly 300 at T0℃, T1℃, and T2℃, where T1 < T0 < T2. Figure 4 As shown, both the reflector 10 and the lens mount 20 expand during temperature increases. The materials of the reflector 10 and the lens mount 20 are different, resulting in a difference in their coefficients of thermal expansion. This causes the reflector 10 and the lens mount 20 to expand or contract to different degrees when the temperature changes, thus altering the surface shape of the reflector 10. In higher temperatures, such as T2℃, the lens mount 20 expands more significantly, exerting an outward stretching force on the reflector 10, which may cause the reflector 10 to become concave. In lower temperatures, such as T1℃, the lens mount 20 contracts more significantly, exerting an inward squeezing force on the reflector 10, which may cause the reflector 10 to become convex. The different degrees of expansion or contraction in different areas of the lens mount 20 may also cause the reflector 10 to twist. Although the volume change caused by temperature variation is not significant, the camera module 1000 is a relatively precise optical system. Even a slight change in the surface shape of the reflector 10 can cause a significant change in image quality, resulting in a reduction in image quality.
[0089] Figure 5 This is a schematic diagram of the structure of a lens mounting bracket provided in an embodiment of this application, as shown below. Figure 5 As shown, the lens mounting bracket 20 includes a floating bracket 21 and a fixed bracket 22. The floating bracket 21 includes a lens mounting portion 211 and a flexible connecting portion 212. The flexible connecting portion 212 connects the lens mounting portion 211 and the fixed bracket 22, allowing the lens mounting portion 211 to move relative to the fixed bracket 22.
[0090] Lens mounting section 211 is used to mount reflector 10. Figure 5 The image also schematically shows a reflector 10.
[0091] In this embodiment, the reflector 10 is mounted by the lens mounting part 211 of the floating bracket 21. The lens mounting part 211 is connected to the fixed bracket 22 by the flexible connection part 212, so that the lens mounting part 211 is in a floating state relative to the fixed bracket 22, and the lens mounting part 211 can move relative to the fixed bracket 22. Figure 6 This is a schematic diagram showing the volume change of a lens mounting bracket affected by temperature, as provided in an embodiment of this application. Figure 6 The image shows the state of the lens mount at T0℃, T1℃, and T2℃, respectively. Figure 6As shown, during the process of temperature change causing volume change of the fixed bracket 22, the flexible connection part 212 can deform with the volume change of the fixed bracket 22, so that the reflector 10 installed on the lens mounting part 211 is protected from the stretching, squeezing and other effects caused by the volume change of the fixed bracket 22, thereby reducing or avoiding the influence of temperature change on the surface shape of the reflector 10, which is beneficial to improving the imaging quality of the camera module 1000.
[0092] Figure 7 This is a schematic diagram of the structure of a lens mounting part provided in an embodiment of this application, as shown below. Figure 7 As shown, the lens mounting portion 211 can be plate-shaped. The lens mounting portion 211 has opposite first surfaces 211a and second surfaces 211b, wherein the first surface 211a is used to mount the reflector 10. As an example, the lens mounting portion 211 is rectangular plate-shaped.
[0093] In other possible implementations, the lens mounting part 211 may also be polygonal, circular or elliptical.
[0094] like Figure 7 As shown, the lens mounting portion 211 may have a hollowed-out area 211c, which can reduce the weight of the lens mounting portion 211. For example, the hollowed-out area 211c may be located at the center of the lens mounting portion 211.
[0095] As an example, the lens mounting part 211 may also include a reinforcing rib 2111, which is located in the hollow area 211c. The reinforcing rib 2111 can improve the structural strength of the lens mounting part 211 and provide support for the reflector 10 at the hollow area 211c.
[0096] In some possible examples, the first surface 211a of the lens mounting portion 211 can also be used to mount light-transmitting components, such as lenses or optical films, which may include filters or polarizers. The cutout area 211c can be used for light transmission. In other words, mounting light-transmitting optical devices through the lens mounting portion 211 can reduce or avoid the influence of temperature changes on the shape of the optical devices, which is beneficial to improving the stability and accuracy of the optical system.
[0097] The flexible connection 212 is connected to at least one side of the lens mounting part 211 to maintain the structural integrity of the lens mounting bracket 20 and to enable the lens mounting part 211 to be in a floating state relative to the fixed bracket 22.
[0098] In the camera module 1000, with the principal optical axis of the lens 100 as a reference, it is generally desirable for the center position of the reflector 10 to remain constant during the process of the reflector component 300 changing in volume due to temperature changes. This is because movement of the reflector 10 relative to the principal optical axis of the lens 100 will affect image quality. For example, some light transmitted through the lens 100 may not reach the reflector 10; or, the surface of the reflector 10 is not perfectly smooth, and the flatness varies in different areas, resulting in differences in the light reflection effect in different areas. Even if the light entering the lens 100 remains constant before and after the position of the reflector 10 changes, the distribution of light in the formed image will change, causing an alteration in the image. Similarly, rotation of the reflector 10 will also cause an alteration in the image, affecting image quality. By configuring the structure of the flexible connection part 212, the lens mounting part 211 becomes more stable, thereby reducing the positional change of the lens mounting part 211 during the volume change of the reflector assembly 300 due to temperature influence. This reduces the rotation of the lens mounting part 211, which in turn reduces the positional change and rotation of the reflector 10, thus improving the imaging quality.
[0099] In some examples, the flexible connector 212 can be connected to multiple sides of the lens mounting portion 211. Compared to connecting to only one side of the lens mounting portion 211, connecting to multiple sides can make the lens mounting portion 211 more stable. For example Figure 6 As shown, the flexible connection portion 212 is connected to the opposite sides of the lens mounting portion 211.
[0100] For ease of explanation, a spatial coordinate system is established, wherein the XOY plane is parallel to the first surface 211a of the lens mounting part 211. (Combined with...) Figure 6 In this example, the flexible connection 212 connects to both sides of the lens mounting portion 211 along the X-axis. The flexible connection 212 provides support from opposite sides of the lens mounting portion 211, making the lens mounting portion 211 more stable. When the volume of the fixed bracket 22 changes, causing deformation of the flexible connection 212, the flexible connection 212 exerts a reverse force on the lens mounting portion 211 in the X-axis extension direction, making the forces on the lens mounting portion 211 more balanced, thus making the lens mounting portion 211 more stable and improving the imaging quality of the camera module 1000.
[0101] Figure 8 This is a schematic diagram of a floating support structure provided in an embodiment of this application, as shown below. Figure 8 As shown, each side of the lens mounting portion 211 connected to the flexible connecting portion 212 may have two connections to the flexible connecting portion 212.
[0102] In this example, the lens mounting portion 211 is connected to the flexible connecting portion 212 on both sides along the X-axis, and each side has two spaced-apart connections to the flexible connecting portion 212. That is, there are two connection points between one side of the lens mounting portion 211 and the flexible connecting portion 212. By increasing the number of connection points, rotation of the lens mounting portion 211 can be suppressed, for example, in... Figure 8 In the example shown, the rotation of the lens mounting part 211 around the X-axis can be suppressed, thereby improving the stability of the lens mounting part 211 and further reducing the impact of temperature changes on the reflector 10.
[0103] For example, Figure 9 This is a schematic diagram of a floating support structure provided in an embodiment of this application, as shown below. Figure 9 As shown, the flexible connection portion 212 is arranged around the lens mounting portion 211.
[0104] The flexible connector 212 surrounds the outside of the lens mounting portion 211, so that each side of the lens mounting portion 211 can be connected to the flexible connector 212. This allows the lens mounting portion 211 to be restricted by the flexible connector 212 in multiple directions, thus making it more stable.
[0105] In some examples, the flexible connection 212 may also be arranged symmetrically about the lens mounting part 211.
[0106] The symmetry here can be any of the following: axial symmetry, surface symmetry, rotational symmetry, and central symmetry. The axis of symmetry can pass through the geometric center of the first surface 211a of the lens mounting part 211; the plane of symmetry can pass through the geometric center of the first surface 211a of the lens mounting part 211; and the center of rotational symmetry can be the geometric center of the first surface 211a of the lens mounting part 211.
[0107] The symmetrically arranged flexible connecting parts 212 exert a more symmetrical force on the lens mounting part 211, which can make the lens mounting part 211 more stable.
[0108] During temperature changes that cause volume changes in the fixed support 22, the flexible connection 212 reduces the compression or stretching of the lens mounting portion 211 by deforming, thereby minimizing changes in the surface shape of the reflector 10. By configuring the structure of the flexible connection 212, it can better deform with changes in the volume of the fixed support 22. Figures 5-9 The shape shown is not the actual form of the flexible connection 212; the flexible connection 212 is only represented by a broken line in the figure.
[0109] In some examples, the flexible connection 212 may include multiple elastic elements, each connected to the lens mounting portion 211 and the fixing bracket 22 respectively. Exemplarily, the elastic elements may include at least one of a spring, a sheet spring, and an elastic arm. By arranging multiple elastic elements to connect the lens mounting portion 211 and the fixing bracket 22, the elastic deformation of the multiple elastic elements compensates for dimensional changes in the fixing bracket 22 caused by temperature variations, thus preventing the lens mounting portion 211 from being directly stretched or compressed by the fixing bracket 22. When the temperature returns to its pre-change state, the elastic elements can recover under their own elastic force.
[0110] As an example, Figure 10 This is a schematic diagram of a floating support structure provided in an embodiment of this application, as shown below. Figure 10 As shown, in the floating support 21, the flexible connection 212 includes a fixing part 2121 and a plurality of spring pieces 2123. Each spring piece 2123 has its two ends connected to the lens mounting part 211 and the fixing part 2121, respectively. The fixing part 2121 is used to connect to the fixed support 22. Each spring piece 2123 provides a force that causes the lens mounting part 211 to move closer to or further away from the fixed support 22.
[0111] As an example, Figure 11 This is a schematic diagram of a floating support structure provided in an embodiment of this application, as shown below. Figure 11 As shown, in the floating support 21, the flexible connection portion 212 includes a fixed portion 2121 and a plurality of elastic arms 2122. The fixed portion 2121 is connected to the fixed support 22. The first end of the elastic arm 2122 is connected to the lens mounting portion 211, and the second end of the elastic arm 2122 is connected to the fixed portion 2121. Each elastic arm 2122 provides a force that causes the lens mounting portion 211 to move closer to or further away from the fixed support 22.
[0112] Multiple elastic arms 2122 support the lens mounting section 211. During expansion of the fixed bracket 22, the fixed bracket 22 pulls the elastic arms 2122 away from the lens mounting section 211, causing deformation. During contraction of the fixed bracket 22, the fixed bracket 22 compresses the elastic arms 2122 towards the lens mounting section 211, causing deformation. The elastic deformation of the elastic arms 2122 compensates for dimensional changes in the fixed bracket 22 caused by temperature variations, thereby preventing the lens mounting section 211 from being directly stretched or compressed by the fixed bracket 22, reducing the impact on the reflector 10. The multiple elastic arms 2122 are structurally independent, facilitating individual design of their structure or distribution, resulting in a more balanced force on the lens mounting section 211 and greater stability.
[0113] like Figure 11As shown, at least a portion of the elastic arm 2122 extends along the edge of the lens mounting portion 211.
[0114] Electronic devices typically have a suitable operating temperature range; outside this range, they may malfunction. The suitable operating temperature range usually varies between different electronic devices. The extension of the elastic arm 2122 or a portion thereof along the edge of the lens mounting portion 211 indicates that, within the suitable operating temperature range of the electronic device, there exists at least one temperature at which the elastic arm 2122 or a portion thereof is parallel to the edge of the lens mounting portion 211. As an example, at room temperature, such as 25°C, the elastic arm 2122 is parallel to the edge of the lens mounting portion 211.
[0115] exist Figure 11 In the middle, the elastic arm 2122 extends along the edge of the lens mounting part 211. Figure 12 This is a schematic diagram of a floating support structure provided in an embodiment of this application. Figure 12 The diagram shows the shape of the floating support 21 after the fixed support 22 expands. (As shown...) Figure 12 As shown, during the outward expansion of the fixed bracket 22, one end of the elastic arm 2122 moves away from the lens mounting part 211, and the angle between the elastic arm 2122 and the edge of the lens mounting part 211 increases.
[0116] By extending at least a portion of the elastic arm 2122 along the edge of the lens mounting portion 211, it is beneficial to reduce the space occupied by the elastic arm 2122, thereby leaving more space for the lens mounting portion 211, which is beneficial for arranging a larger reflector 10.
[0117] As an example, multiple elastic arms 2122 can be distributed on opposite sides of the lens mounting portion 211, with two elastic arms 2122 distributed on each opposite side. Two elastic arms 2122 located on the same side of the lens mounting portion 211 can also be arranged symmetrically.
[0118] In some other possible implementations, each side of the lens mounting portion 211 may be provided with elastic arms 2122.
[0119] Figure 13 This is a schematic diagram of a floating support structure provided in an embodiment of this application, as shown below. Figure 13As shown, in this example, the elastic arm 2122 includes a first segment 21221 and a second segment 21222. One end of the first segment 21221 and one end of the second segment 21222 are connected together. The other end of the first segment 21221 is connected to the lens mounting portion 211, and the other end of the second segment 21222 is connected to the fixing portion 2121. The first segment 21221 extends along one of the two adjacent sides of the lens mounting portion 211, and the second segment 21222 extends along the other of the two adjacent sides of the lens mounting portion 211.
[0120] During temperature changes, the volume change of the fixing bracket 22 is not unidirectional. For example, during a temperature rise, the fixing bracket 22 expands in multiple directions. By providing a first segment 21221 and a second segment 21222 extending along two adjacent sides of the lens mounting portion 211, the elastic arm 2122 can compensate for the dimensional changes of the fixing bracket 22 in multiple directions, reducing the impact of the volume change of the fixing bracket 22 on the lens mounting portion 211, thereby reducing the impact on the reflector 10.
[0121] by Figure 13 Taking the floating support 21 as an example, the expansion of the fixed support 22 can be decomposed into expansion along the direction parallel to the X-axis and expansion along the direction parallel to the Y-axis. The force exerted by the fixed support 22 on the floating support 21 during the expansion process can also be decomposed into tension force parallel to the X-axis and tension force parallel to the Y-axis. Figure 14 This is a schematic diagram of a floating support structure provided in an embodiment of this application, as shown below. Figure 14 As shown, in this example, the elastic arm 2122 is a bent structure. The expansion of the fixed bracket 22 in the direction parallel to the X-axis causes the first segment 21221 of the elastic arm 2122 to deform. The end of the first segment 21221 of the elastic arm 2122 away from the lens mounting part 211 moves away from the lens mounting part 211, and the angle between the first segment 21221 and the lens mounting part 211 increases. The elastic deformation generated by the first segment 21221 of the elastic arm 2122 compensates for the dimensional change of the fixed bracket 22 in the direction parallel to the X-axis, and avoids the lens mounting part 211 being stretched in the direction of the X-axis. The expansion of the fixed bracket 22 along the direction parallel to the Y-axis causes the second segment 21222 of the elastic arm 2122 to deform. The end of the second segment 21222 of the elastic arm 2122 away from the first segment 21221 moves away from the lens mounting part 211, and the angle between the second segment 21222 and the lens mounting part 211 increases. The elastic deformation generated by the second segment 21222 of the elastic arm 2122 compensates for the dimensional change of the fixed bracket 22 in the direction parallel to the Y-axis, and avoids the lens mounting part 211 being stretched along the Y-axis.
[0122] As an example, the first segment 21221 and the second segment 21222 of the elastic arm 2122 can be perpendicular to each other.
[0123] In some examples, the second end of the partial elastic arm 2122 can be connected, which helps to make the lens mounting part 211 more stable.
[0124] like Figure 14 As shown, in this example, the flexible connection 212 includes four elastic arms 2122, which are divided into two groups, each group including two elastic arms 2122. The second ends of the two elastic arms 2122 in the same group are connected and connected to the fixing part 2121. In the illustrated state, when the fixing bracket 22 expands in a direction parallel to the Y-axis, the deformation of the elastic arms 2122 connected at their second ends in the direction parallel to the Y-axis is equal, and the force exerted on the lens mounting part 211 is similar in magnitude. This helps to improve the stability of the lens mounting part 211 and avoids the lens mounting part 211 from rotating significantly due to the large difference in the force exerted on the lens mounting part 211 caused by the different deformation of the elastic arms 2122.
[0125] like Figure 14 As shown, the elastic arm 2122 also has a notch 2122a, and the cross-sectional area of the elastic arm 2122 inside the notch 2122a is smaller than the cross-sectional area outside the notch 2122a.
[0126] By providing a notch 2122a on the elastic arm 2122, the stiffness of the elastic arm 2122 is reduced, making the elastic arm 2122 more prone to deformation during the process of changes in the volume of the fixed bracket 22.
[0127] The elastic arm 2122 may have multiple notches 2122a, which may be distributed on both sides of the elastic arm 2122. The notches 2122a may be located near the end of the elastic arm 2122 or at a bend in the elastic arm 2122. During the change in volume of the fixing bracket 22, the deformation of the elastic arm 2122 mainly occurs at the connection between the elastic arm 2122 and the lens mounting part 211, the connection between the elastic arm 2122 and the fixing part 2121, and the bend in the elastic arm 2122. Arranging the notches 2122a at these locations helps to reduce the stress in the elastic arm 2122, making it easier for the elastic arm 2122 to deform.
[0128] Figures 11-14 In the floating bracket 21 shown, multiple elastic arms 2122 are symmetrically distributed about the lens mounting part 211 or centrally symmetrically distributed about the lens mounting part 211. Figure 15 This is a schematic diagram of a floating support structure provided in an embodiment of this application, as shown below. Figure 15 As shown, in this example, the multiple elastic arms 2122 of the flexible connection 212 are rotationally symmetrical about the lens mounting part 211.
[0129] Figure 16This is a schematic diagram of a floating support structure provided in an embodiment of this application, as shown below. Figure 16 As shown, in this example, the flexible connection 212 includes eight elastic arms 2122. The eight elastic arms 2122 are divided into four groups, and the four groups of elastic arms 2122 are rotationally symmetrically distributed. Each group includes two elastic arms 2122. The second ends of the two elastic arms 2122 in the same group are connected and connected to the fixing part 2121. The two elastic arms 2122 in the same group can be perpendicular to each other.
[0130] exist Figures 11-16 In the floating bracket 21 shown, the fixing part 2121 includes a frame 21210, and multiple elastic arms 2122 and lens mounting part 211 are all located inside the frame 21210.
[0131] By connecting multiple elastic arms 2122 into one unit through the frame 21210, the overall structure of the floating bracket 21 can be made more stable and less prone to deformation during the manufacturing process.
[0132] Figure 17 This is a schematic diagram of the structure of a lens mounting bracket provided in an embodiment of this application, as shown below. Figure 17 As shown, in the lens mounting bracket 20, the fixing part 2121 can be embedded in the fixing bracket 22.
[0133] Embedding the fixing part 2121 into the fixing bracket 22 can make the connection between the floating bracket 21 and the fixing bracket 22 more secure and prevent the floating bracket 21 from loosening.
[0134] In some examples, the floating bracket 21 can be a metal part, including pure metal parts and alloy parts, such as stainless steel parts and titanium alloy parts; the fixed bracket 22 can be an injection molded part. The lens mounting bracket 20 can be formed by insert molding. That is, the fixing part 2121 of the floating bracket 21 is placed into the cavity of the mold used to form the fixed bracket 22. During the molding process of the fixed bracket 22, the fixed bracket 22 is wrapped around the fixing part 2121, so that the fixing part 2121 of the floating bracket 21 is embedded in the fixed bracket 22 and firmly connected to the fixed bracket 22.
[0135] For example, the floating support 21 can be made of Invar steel or titanium alloy. Both Invar steel and titanium alloy have relatively low coefficients of thermal expansion, which reduces the likelihood of severe relative deformation between the lens mounting portion 211 and the reflector 10 during temperature changes, thus minimizing the impact of temperature on the surface shape of the reflector 10. A material with a coefficient of thermal expansion similar to that of the reflector 10 can be selected for the floating support 21. For example, the reflector 10 can be made of fused silica, with a coefficient of thermal expansion of 0.5e. -6 The floating support 21 can be made of Invar steel, which has a coefficient of thermal expansion of 1.0 e. -6The coefficient of thermal expansion of silicon carbide is similar to that of fused silica; the reflector 10 is made of silicon carbide, with a coefficient of thermal expansion of 4.4e. -6 The floating support 21 can be made of titanium alloy TC4, which has a coefficient of thermal expansion of 8.6 e.g. -6 Its coefficient of thermal expansion is similar to that of silicon carbide.
[0136] like Figure 17 As shown, the fixing part 2121 may also have multiple through holes 2121a. During the injection molding of the fixing bracket 22, the injection material can enter the through holes 2121a, thereby making the fixing part 2121 and the fixing bracket 22 more firmly connected.
[0137] Figure 18 This is a schematic diagram of a floating support structure provided in an embodiment of this application, as shown below. Figure 18 As shown, in this example, the fixing part 2121 includes a plurality of sub-fixing parts 21211, each sub-fixing part 21211 being connected to the first end of an elastic arm 2122. Figure 19 This is a schematic diagram of a floating support structure provided in an embodiment of this application, as shown below. Figure 19 As shown, in this example, each sub-fixing part 21211 is connected to the first end of the two elastic arms 2122.
[0138] By connecting the elastic arm 2122 and the fixing bracket 22 with multiple independent sub-fixing parts 21211, the stress on the fixing part 2121 can be reduced. As the volume of the fixing bracket 22 changes due to temperature, the direction of the force exerted by the fixing bracket 22 on the fixing part 2121 is either closer to or farther from the lens mounting part 211. For example, when the fixing bracket 22 expands, it exerts a pulling force on the fixing part 2121 in a direction away from the lens mounting part 211. Since each sub-fixing part 21211 is located at a different position on the fixing bracket 22, the direction of the pulling force on each sub-fixing part 21211 is also different. The multiple sub-fixing parts 21211 are independent of each other and not directly connected. Each sub-fixing part 21211 can move independently as the fixing bracket 22 expands, without mutually restricting each other and creating significant stress.
[0139] In this embodiment, the arrangement of the elastic arm 2122 can also be incorporated into examples where the elastic element is a spring or a sheet, provided there is no contradiction.
[0140] Figure 20 This is a schematic diagram of the structure of a lens mounting bracket provided in an embodiment of this application, as shown below. Figure 20As shown, in the lens mounting bracket 20, the fixed bracket 22 includes a base plate 221, the base plate 221 has a receiving groove 221a, and the floating bracket 21 is located in the receiving groove 221a. The floating bracket 21 is connected to the side wall of the receiving groove 221a.
[0141] Arranging the floating bracket 21 within the receiving slot 221a reduces the size of the lens mounting bracket 20, which helps to reduce the space occupied by the reflector 300 inside the electronic device.
[0142] For example, the fixing part 2121 of the floating bracket 21 can be embedded in the side wall of the receiving groove 221a.
[0143] like Figure 20 As shown, there is a gap between the second surface 211b of the lens mounting portion 211 and the fixing bracket 22. In this example, the lens mounting portion 211 is located in the receiving groove 221a, and there is a gap between the second surface 211b and the bottom of the receiving groove 221a.
[0144] By setting a gap, the second surface 211b of the lens mounting part 211 is prevented from directly contacting the fixing bracket 22. In this way, as the volume of the fixing bracket 22 increases, the side of the fixing bracket 22 facing the second surface 211b will not exert an outward thrust on the lens mounting part 211 when it expands outward, that is, it will not exert a thrust along the Z-axis on the lens mounting part 211, which can make the lens mounting part 211 more stable.
[0145] As an example, the receiving groove 221a can penetrate through the base plate 221, so that there is more space to accommodate the floating bracket 21 while the thickness of the base plate 221 remains unchanged, reducing the height of the floating bracket 21 protruding from the surface of the base plate 221, or even making the floating bracket 21 not protrude from the surface of the base plate 221, thereby making the structure of the lens mounting bracket 20 more compact.
[0146] like Figure 20 As shown, the fixing bracket 22 also includes a reinforcing piece 222, which can be located on one side of the base plate 221 and arranged opposite to the second surface 211b of the lens mounting part 211. The reinforcing piece 222 is connected to the base plate 221. The receiving groove 221a penetrating the base plate 221 would reduce the structural strength of the base plate 221. By providing the reinforcing piece 222, the structural strength of the fixing bracket 22 is improved.
[0147] For example, the reinforcing piece 222 can be a metal sheet, such as a stainless steel sheet or an aluminum alloy sheet. The reinforcing piece 222 can be bonded to the base plate 221 by adhesive or connected to the base plate 221 by an insert molding process.
[0148] like Figure 20As shown, the lens mounting bracket 20 also includes a buffer pad 23. The buffer pad 23 is located on the second surface 211b of the lens mounting portion 211. The buffer pad 23 may contact the fixing bracket 22, or there may be a gap between the buffer pad 23 and the fixing bracket 22.
[0149] In this example, by arranging a buffer pad 23 on the second surface 211b of the lens mounting portion 211, the lens mounting portion 211 can be supported, preventing the flexible connection portion 212 from undergoing plastic deformation and becoming unable to recover.
[0150] When an electronic device is subjected to an external impact, such as when it falls and collides with the ground, the lens mounting part 211 will move relative to the fixed bracket 22 under the action of inertia. During this process, the flexible connection part 212 will deform. When the movement of the lens mounting part 211 under the action of inertia has a component along the Z-axis, the gap between the second surface 211b and the fixed bracket 22 becomes smaller. The buffer pad 23 can reduce the impact and reduce the movement distance of the lens mounting part 211, thereby preventing the flexible connection part 212 from undergoing excessive deformation and being unable to recover, and preventing the flexible connection part 212 from breaking due to excessive deformation.
[0151] The cushioning pad 23 may be made of a super-elastic material. For example, the material of the cushioning pad 23 may be at least one of rubber, silicone, and foam.
[0152] Figure 21 This is a schematic diagram of the arrangement of a buffer pad provided in an embodiment of this application, as shown below. Figure 21 As shown, the buffer pad 23 can be arranged at the corner of the second surface 211b of the lens mounting part 211. This allows the buffer pad 23 to be located away from the center of the reflector 10, preventing the center of the reflector 10 from bulging outward due to the support of the buffer pad 23 during the process of the buffer pad 23 absorbing the impact.
[0153] As an example, the cross-section of the buffer pad 23 can be cross-shaped, and the cross-section of the buffer pad 23 is parallel to the second surface 211b of the lens mounting portion 211. This shape of buffer pad 23 is not easily bent.
[0154] Figure 22 This is a schematic diagram of the structure of a reflective component provided in an embodiment of this application, as shown below. Figure 22 As shown, the reflective assembly includes a reflector 10 and a lens mounting bracket 20. Figure 23 This is a schematic diagram of the internal structure of a reflective component provided in an embodiment of this application, as shown below. Figure 23 As shown, the reflector 10 is connected to the lens mounting portion 211 of the lens mounting bracket 20. The lens mounting bracket 20 can be... Figures 5 to 21 Any of the lens mounting brackets 20 shown.
[0155] For example, the reflector 10 can be bonded to the first surface 211a of the lens mounting portion 211.
[0156] In this embodiment, the reflector 10 is mounted on the lens mounting portion 211, which is connected to the fixed bracket 22 via a flexible connection portion 212. This allows the reflector 10 to float relative to the fixed bracket 22, enabling it to move relative to the fixed bracket 22 with the lens mounting portion 211. During temperature changes that cause volume changes in the reflective assembly, the flexible connection portion 212, with its low stiffness, deforms with the volume changes of the fixed bracket 22 and the reflector 10, compensating for the relative deformation of the fixed bracket 22 and the reflector 10. This protects the reflector 10 from stretching and compression caused by the volume changes of the fixed bracket 22, thereby reducing or avoiding the impact of temperature changes on the surface shape of the reflector 10 and improving the imaging quality of the camera module 1000.
[0157] Furthermore, since the reflector 10 is suspended relative to the fixed support 22, the volume change of the fixed support 22 due to temperature has a smaller impact on the reflector 10. Therefore, when manufacturing the reflective assembly, the requirements for matching the coefficients of thermal expansion of different materials can be reduced, allowing for a wider range of material choices. This facilitates flexible material selection based on factors such as cost, machinability, material density, and material strength. Moreover, temperature changes have a smaller impact on the surface shape of the reflector 10, reducing the precision requirements for its processing and thus lowering the manufacturing difficulty and production yield.
[0158] like Figure 23 As shown, the side of the reflector 10 away from the lens mounting portion 211 has a reflective portion 10a and a screen printing portion 10b, the screen printing portion 10b surrounding the reflective portion 10a, and the reflective portion 10a is used to reflect light.
[0159] The reflector 10 can be made of glass, fused silica, or silicon carbide. For example, if the reflector 10 is made of fused silica, the floating support 21 can be made of Invar; or if the reflector 10 is made of silicon carbide, the floating support 21 can be made of titanium alloy TC4.
[0160] Figure 24 This is an exploded structural diagram of a light-transmitting component provided in an embodiment of this application, as shown below. Figure 24 As shown, the light-transmitting assembly may include a light-transmitting element 60 and a lens mounting bracket 20, wherein the lens mounting bracket 20 may be... Figures 5 to 21Any of the lens mounting brackets 20 shown. The light-transmitting element 60 is connected to the lens mounting portion 211 of the floating bracket 21. The light-transmitting element 60 refers to a light-transmitting optical device, such as a lens or optical film, which may include a filter or polarizer. By mounting the light-transmitting element 60 on the lens mounting portion 211, the light-transmitting element 60 is in a floating state, which can reduce or avoid the influence of temperature changes on the shape of the light-transmitting element 60, and is beneficial to improving the stability and accuracy of the optical system.
[0161] Figure 25 This is an exploded structural diagram of a photosensitive structure provided in an embodiment of this application, as shown below. Figure 25 As shown, the photosensitive structure may include a circuit board 201, a photosensitive chip 202, and as shown in the figure. Figure 24 The light-transmitting component shown has a photosensitive chip 202 connected to a circuit board 201. The light-transmitting element 60 of the light-transmitting component is arranged opposite to the photosensitive area of the photosensitive chip 202, and the light passing through the light-transmitting element 60 can illuminate the photosensitive area of the photosensitive chip 202.
[0162] The lens mounting bracket 20 in the light-transmitting component can reduce or avoid the influence of temperature changes on the shape of the light-transmitting element 60, which helps to reduce the impact of temperature on the photosensitive structure and improve the stability and accuracy of the photosensitive structure.
[0163] Figure 26 This is an exploded view of a camera module provided in an embodiment of this application, as shown below. Figure 26 As shown, the camera module includes a lens 100, a photosensitive structure 200, and a... Figure 22 The reflective component 300 shown. Figure 27 This is a schematic diagram of the internal structure of a camera module provided in an embodiment of this application, as shown below. Figure 27 As shown, the reflector 300 is located on the image side of the lens 100 to reflect the light transmitted through the lens 100 to the photosensitive structure 200.
[0164] like Figure 26 As shown, in the reflector assembly 300, the fixed bracket 22 also includes a first frame 223 and a second frame 224. The base plate 221, the first frame 223 and the second frame 224 are arranged at an angle. The first frame 223 can be used to connect the lens 100 and the second frame 224 can be used to connect the photosensitive structure 200.
[0165] Lens 100 may include a first lens barrel 101 and a plurality of first lenses 102, the plurality of first lenses 102 being located within the first lens barrel 101. The first lens barrel 101 is connected to a first frame 223. As an example, lens 100 may include two first lenses 102, the two first lenses 102 being coaxially arranged within the first lens barrel 101.
[0166] The photosensitive structure 200 may include a circuit board 201 and a photosensitive chip 202, which is connected to the circuit board 201, for example, by bonding it to the circuit board 201. The photosensitive chip 202 and the circuit board 201 may also be electrically connected for transmitting electrical signals. The photosensitive chip 202 faces the reflector 300 to receive light reflected by the reflector 300.
[0167] In some examples, the photosensitive structure 200 may also include an optical film 203 located on the side of the photosensitive chip 202 closer to the reflective assembly 300. For example, the optical film 203 may be a filter.
[0168] like Figure 26 As shown, the photosensitive structure 200 may further include an optical film holder 204, which is located on the side of the circuit board 201 near the reflector assembly 300. Exemplarily, the optical film holder 204 may be bonded to the circuit board 201. The optical film 203 is connected to the optical film holder 204.
[0169] In this example, the camera module may further include a motor 400 and a dimming assembly 500, with the dimming assembly 500 located within the motor 400. The motor 400 may be located between the second frame 224 and the photosensitive structure 200. The motor 400 includes a housing 401 and a drive mechanism located within the housing 401. The housing 401 of the motor 400 may be connected to the second frame 224; for example, the housing 401 may be bonded to the second frame 224 and the optical film support 204. The drive mechanism of the motor 400 is used to drive the dimming assembly 500 for focusing or image stabilization. The drive mechanism of the motor 400 may include a mover 402 and a stator 403.
[0170] The dimming assembly 500 includes a second lens barrel 501 and a plurality of second lenses 502, the plurality of second lenses 502 being located within the second lens barrel 501. As an example, the dimming assembly 500 may include three second lenses 502, the three second lenses 502 being coaxially arranged within the second lens barrel 501.
[0171] The second lens barrel 501 can be connected to the mover 402 of the motor 400, so that it can move between the reflector assembly 300 and the photosensitive structure 200 under the drive of the mover 402. For example, the second lens barrel 501 can move closer to or further away from the photosensitive chip 202 under the drive of the mover 402.
[0172] In other examples, the photosensitive structure 200 of the camera module can also be... Figure 25 The photosensitive structure shown.
