Description

Technical Field

[0001] The present application relates to the field of photographing technology, and in particular to a supporting seat, a refractive device, an optical lens, a camera module and an electronic device. Background Art

[0002] With technological advancements, camera modules are increasingly used in electronic devices. Periscope camera modules feature a refraction device to redirect light. The refraction element in this refraction device is connected to the support base via an elastic member, a deformable structure. If the electronic device is dropped, the elastic member can deform, causing the refraction element to deviate from its preset position, thus affecting the camera module's optical performance. Utility Model Content

[0003] The embodiment of the present application provides a supporting seat, a refraction device, an optical lens, a camera module and an electronic device. The refraction device in the embodiment of the present application has high structural stability and good optical performance.

[0004] In a first aspect, an embodiment of the present application provides a bearing seat for use in a refractive device, wherein the refractive device includes an elastic member and a refractive element. The bearing seat includes a mounting portion, a support portion, and a first side and a second side arranged opposite to each other in a first direction, wherein the first side is the light incident side of the bearing seat. In other words, light enters the bearing seat from the first side. The mounting portion is located between the first side and the second side, the support portion is fixedly connected to the edge of the mounting portion close to the second side, the mounting portion and the support portion are enclosed to form an installation space, the installation space is used to install the refractive element, the elastic member connects the bearing seat and the refractive element, and the support portion is used to stop the refractive element. It can be understood that the support portion protrudes from the surface of the mounting portion.

[0005] In the embodiment of the present application, a support portion is provided. When the support seat falls along the arrangement direction of the mounting portion and the support portion, or falls along the arrangement direction of the first side and the second side and stops falling, the support portion abuts against the refractive element, providing support for the refractive element, thereby preventing the refractive element from falling or shaking, which may cause the combination formed by the refractive element and the elastic member to produce elastic-plastic deformation, thereby affecting the imaging quality of the camera module. If the support portion is not provided, when the support seat falls along the arrangement direction of the mounting portion and the support portion, or falls along the arrangement direction of the first side and the second side and stops falling, the refractive element falls or shakes along the mounting portion, causing the elastic member to deform, causing the refractive element to deviate from the preset position. When the refractive device takes pictures again after falling, the imaging quality of the camera module is affected. The refractive device in the embodiment of the present application has high structural stability and good optical performance.

[0006] In one possible embodiment, the refractive element includes a first portion and a second portion, the mounting portion and the first portion are arranged correspondingly in the first direction, the mounting portion and the second portion are staggered in the first direction, the area of ​​the surface of the support portion facing the refractive element is a first area, the area of ​​the projection of the second portion on the plane on which the support portion resides is a second area, and the ratio of the first area to the second area is greater than or equal to 5%. In other words, the first portion is above the mounting portion, and the second portion is above the support portion. Exemplarily, the ratio of the first area to the second area can be 10%, 15%, 20%, 25%, 30%, 35%, 45%, 55%, or 70%, etc. By setting the ratio of the first area to the second area to be greater than or equal to 5%, the contact area between the support portion and the refractive element is increased, sufficient support is provided for the refractive element, and the structural stability of the refractive device is improved.

[0007] In a possible implementation manner, the thickness of the support portion is greater than or equal to 0.2 mm, and / or the length of the support portion is greater than or equal to 1 mm, and / or the width of the support portion is greater than or equal to 1 mm.

[0008] For example, the thickness of the support portion can be 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, or 1.5 mm, etc. Setting the thickness of the support portion to be greater than or equal to 0.2 mm helps to improve the structural strength of the support portion, provide sufficient support for the refractive element, and improve the structural stability of the refractive device.

[0009] For example, the length of the support portion can be 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 3 mm, 4 mm, or 5 mm. Setting the length of the support portion to be greater than or equal to 1 mm helps increase the contact area between the support portion and the refractive element, providing sufficient support for the refractive element and improving the structural stability of the refractive device.

[0010] For example, the width of the support portion can be 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 3 mm, 4 mm, or 5 mm. Setting the width of the support portion to be greater than or equal to 1 mm helps increase the contact area between the support portion and the refractive element, providing sufficient support force for the refractive element and improving the structural stability of the refractive device. Furthermore, setting the width of the support portion to be greater than or equal to 1 mm allows the support portion to be wider, thereby preventing the refractive element from detaching from the support portion when the refractive device is dropped.

[0011] In one possible embodiment, a gap is provided between the support portion and the refractive element. When the refractive element is mounted on the support base, spacing the refractive element from the support portion helps prevent the refractive element from colliding with the support portion during installation, thereby damaging the refractive element and potentially affecting the imaging quality of the camera module or damaging the refractive element. By spacing the refractive element from the support portion, the refractive element is less likely to collide with the support portion during installation, improving installation efficiency and yield, and preventing damage to the refractive element.

[0012] In one possible embodiment, the spacing between the support portion and the refractive element is less than or equal to 0.5 mm. By setting the spacing between the refractive element and the support portion to be less than or equal to 0.5 mm, it is advantageous to avoid the refractive element colliding with the support portion during installation, causing damage to the refractive element, thereby reducing the installation efficiency and installation yield of the refractive element, and affecting the imaging quality of the camera module. By setting the spacing between the refractive element and the support portion to be less than or equal to 0.5 mm, the spacing between the refractive element and the support portion is smaller, and when the refractive device falls along the arrangement direction of the installation portion and the support portion or falls along the arrangement direction of the first side and the second side and stops falling, the support portion can support the refractive element, provide support force for the refractive element, and avoid deformation of the elastic member.

[0013] In one possible embodiment, the surface of the support portion facing the refractive element is parallel to the surface of the refractive element facing the support portion. It is understood that the surface of the support portion facing the refractive element and the surface of the refractive element facing the support portion are arranged to correspond to each other. By arranging the surface of the support portion facing the refractive element to be parallel to the surface of the refractive element facing the support portion, the contact area between the refractive element and the support portion can be increased. When the refractive device falls, the support portion can provide sufficient support for the refractive element, which helps to improve the structural stability of the refractive device.

[0014] In a possible embodiment, the support portion and the mounting portion are integrally formed and can be integrally formed by injection molding, so that the support seat has high structural strength, simple manufacturing process and low cost.

[0015] In a possible embodiment, the support portion is a square, a circular partial structure, an elliptical partial structure, a trapezoidal or a triangular shape. The support portion can be of any shape, and the embodiment of the present application does not limit the shape of the support portion.

[0016] In one possible embodiment, the support portion includes an arcuate segment, with two adjacent side surfaces of the support portion connected by the arcuate segment. If the corners of the support portion are sharp, the support portion may damage the refractive element when installing the refractive element. By connecting the two adjacent side surfaces of the support portion with an arcuate segment, the corners of the support portion are smoother, preventing damage to the refractive element during installation.

[0017] In one possible embodiment, the support portion is located in a middle region of the edge of the mounting portion proximal to the second side. It is understood that the support portion corresponds to a middle position of the edge of the refractive element. When the refractive element is mounted on the support base, the support portion corresponds to the middle region of the edge of the refractive element, which facilitates providing balanced support for the refractive element and avoids the situation where the support portion deviates from the middle region of the refractive element, resulting in an unbalanced support for the refractive element and causing the refractive element to tilt, thereby affecting the imaging effect of the camera module.

[0018] In one possible embodiment, the bearing seat includes a buffer member, the buffer member being located between the support portion and the refractive element, and / or the buffer member being located between the elastic member and the refractive element. For example, the buffer member can be fixed to the support portion, and after the refractive element is mounted on the bearing seat, the buffer member is located between the support portion and the refractive element. The buffer member can play a cushioning role. When the refractive device falls along the arrangement direction of the mounting portion and the support portion, or falls along the arrangement direction of the first side and the second side and stops falling, the refractive element hits the buffer member, causing the buffer member to deform, releasing the impact force received, and avoiding damage to the refractive element. The buffer member can also be fixed to the elastic member, and after the refractive element is mounted on the bearing seat, the buffer member is located between the elastic member and the refractive element. By arranging the buffer member between the elastic member and the refractive element, when the refractive device falls along a direction perpendicular to the arrangement direction of the first side and the second side and perpendicular to the arrangement direction of the mounting portion and the support portion, the buffer member can play a cushioning role, preventing the elastic member from hitting the refractive element and causing damage to the refractive element. In addition, if a buffer member is not provided between the elastic member and the refractive element, when the refractive device falls in a direction perpendicular to the arrangement of the first side and the second side and perpendicular to the arrangement direction of the mounting portion and the supporting portion, the elastic member will also deform, causing the refractive element to deviate from the preset position. When the refractive device takes pictures after falling, the imaging quality of the camera module is affected.

[0019] In one possible embodiment, the buffer is a soft rubber with an elastic modulus of less than or equal to 10 GPa, making the soft rubber sufficiently flexible to provide a good cushioning effect on the refractive element. The soft rubber can be acrylic or other colloids, and the present embodiment does not limit the material of the soft rubber.

[0020] In a second aspect, the present application provides a refractive index device, comprising an elastic member, a refractive element, and a supporting seat as described in any one of the aforementioned embodiments, wherein the elastic member and the refractive element are both located in the supporting seat.

[0021] In a third aspect, the present application provides an optical lens comprising a lens assembly and a diopter device as described in any of the aforementioned embodiments, wherein the diopter device and the lens assembly are arranged on an optical path of the optical lens. The arrangement of the diopter device and the lens assembly on the optical path can be configured as needed and is not limited in the present embodiments.

[0022] In a fourth aspect, the present application provides a camera module, comprising a photosensitive element and the optical lens described in any one of the aforementioned embodiments, wherein the photosensitive element is located on the image side of the optical lens.

[0023] In a fifth aspect, the present application provides an electronic device comprising an image processor and a camera module as described in any one of the aforementioned embodiments, wherein the image processor is communicatively connected to the camera module, and the image processor is used to obtain image data from the camera module and process the image data.

[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] It should be understood that the terms “first”, “second”, etc. used in this application are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0038] In the description of this application, the terms "up", "down", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on this application.

[0039] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, a conflicting connection or an integrated connection; for ordinary technicians in this field, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0040] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of an electronic device 1000. The electronic device 1000 can be a mobile phone, tablet, wearable device, or other device with a photo or video recording function. This application describes the electronic device 1000 as a mobile phone. The electronic device 1000 can include at least one camera module 200.

[0041] The electronic device 1000 may include a housing 100, a camera module 200, and an image processor 300. The camera module 200 and the image processor 300 are located within the housing 100, and the camera module 200 is communicatively connected to the image processor 300. The camera module 200 is used to acquire image data and input the image data into the image processor 300, and the image processor 300 is used to process the image data acquired from the camera module 200. The communication connection between the camera module 200 and the image processor 300 may include data transmission through electrical connection methods such as wiring, or data transmission may be achieved through coupling or other methods. It is understandable that the camera module 200 and the image processor 300 may also be communicatively connected through other methods that can achieve data transmission.

[0042] The image processor 300 optimizes and processes the digital image signal through a series of complex mathematical algorithms, ultimately transmitting the processed signal to the display for display. The image processor 300 can be an image processing chip or a digital signal processing chip (DSP), capable of processing both image and digital signals. Its role is to promptly and quickly transmit data acquired by the camera module 200's photosensitive chip to the central processing unit and refresh the photosensitive chip. Therefore, the quality and stability of the DSP chip directly impact image quality (e.g., color saturation, clarity, etc.).

[0043] In one specific embodiment, the camera module 200 can be disposed on the back of the electronic device 1000, serving as the rear camera of the electronic device 1000. In other embodiments, the camera module 200 can also be disposed on the front of the electronic device 1000, serving as the front lens of the electronic device 1000. Both the front lens and the rear lens can be used for selfies or for the photographer to capture other objects.

[0044] It is understandable that Figure 1 The installation location of the camera module 200 of the electronic device 1000 in the illustrated embodiment is merely illustrative, and this application does not impose strict limitations on the installation location of the camera module 200. In other embodiments, the camera module 200 may be installed in other locations of the electronic device 1000, such as in the upper center or upper right corner of the electronic device 1000. Alternatively, the camera module 200 may be installed not on the main body of the mobile phone, but on an auxiliary component that is movable or rotatable relative to the mobile phone, such as an auxiliary component that can extend, retract, or rotate from the main body of the mobile phone.

[0045] Figure 1 It is just a schematic diagram showing the structure of an electronic device 1000. Figure 1The size, quantity and position of the camera module 200 and image processor 300 shown are only schematic representations and can be adjusted as needed. This application does not limit this.

[0046] like Figure 2 As shown, Figure 2 for Figure 1 The schematic diagram of the structure of a camera module 200 is shown. The camera module 200 may include an optical lens 20 and a photosensitive element 10, and the photosensitive element 10 is located on the image side of the optical lens 20. When the camera module 200 is working, the scene to be imaged passes through the optical lens 20 and is imaged on the photosensitive element 10. It can be understood that the imaging element in the optical lens 20 can be the photosensitive element 10, or other imaging elements, and the present application does not limit this. The working principle of the camera module 200 is: the light reflected by the scene to be photographed passes through the optical lens 20 to generate an optical image projected onto the surface of the photosensitive element 10, and the photosensitive element 10 converts the optical image into an electrical signal, i.e., an analog image signal, and transmits the converted analog image signal to the image processor 300. The embodiment of the present application takes the camera module 200 as a periscope camera module as an example. The camera module 200 can also be a camera module of other forms, and the embodiment of the present application does not limit this.

[0047] The optical lens 20 may include a refractive device 30 and a lens group 40. The lens group 40 may include one lens, two lenses, or three lenses. The embodiment of the present application does not limit the number of lenses in the lens group 40.

[0048] The refraction device 30 and the lens group 40 can be arranged on the optical path of the optical lens 20. For example, the refraction device 30 can be located on the object side of the lens group 40, and the light can pass through the refraction device 30 and the lens group 40 in sequence, and form an image on the photosensitive element 10; or the refraction device 30 can be located on the image side of the lens group 40, and the light can pass through the lens group 40 and the refraction device 30 in sequence, and form an image on the photosensitive element 10; or the lens group 40 can include a first lens group and a second lens group ( Figure 2 (not shown), the refraction device 30 can be located on the image side of the first lens group and on the object side of the second lens group, that is, the refraction device 30 is located between the first lens group and the second lens group. Light can pass through the first lens group, the refraction device 30, and the second lens group in sequence, and form an image on the photosensitive element 10. The number of lenses in the first lens group and the second lens group can be one, two, or three, etc., which is not limited in this embodiment of the present application. Figure 2 Take the case where the refraction device 30 is located on the object side of the lens assembly 40 as an example.

[0049] Figure 2 It is just a schematic diagram showing the structure of a camera module 200. Figure 2The structure, size, number and position of the refractive device 30 and the lens group 40 shown are only schematic representations, and the number and structure of the lenses in the lens group 40 are also only schematic representations and can be adjusted as needed. This application does not impose any restrictions on this.

[0050] like Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, Figure 3 for Figure 2 A schematic structural diagram of a refraction device 30 is shown, Figure 4 for Figure 3 The partial structural diagram of the refraction device 30 is shown. Figure 5 for Figure 3 The exploded structural diagram of part of the structure of the refraction device 30 is shown. Figure 6 for Figure 3 The structural diagram of the support seat 33 is shown. It is understood that for the convenience of description, the definition Figure 3 The deflecting device 30 shown has a third direction X, a second direction Y, and a first direction Z. The second direction Y is perpendicular to the third direction X, and the first direction Z is perpendicular to both the third direction X and the second direction Y. The third direction X may be parallel to the width of the deflecting device 30. The dimension of the deflecting device 30 in the third direction X (i.e., the width of the deflecting device 30) may be greater than, less than, or equal to the dimension of the deflecting device 30 in the second direction Y (i.e., the length of the deflecting device 30).

[0051] The refractive index device 30 may include a housing 31, a support base 33, an elastic member, and a refractive element 34. In this embodiment, two elastic members are used as an example, namely a first elastic member 321 and a second elastic member 322. In other embodiments, the number of elastic members may also be one, and this embodiment does not limit the number of elastic members.

[0052] The housing 31 may include a housing cavity 311, a light inlet 312, and a light outlet 313. The housing cavity 311 may be used to accommodate the support seat 33, the refractive element 34, the first elastic member 321, the second elastic member 322, and the like. In other words, the support seat 33, the refractive element 34, the first elastic member 321, and the second elastic member 322 are located in the housing cavity 311 of the housing 31. The light inlet 312 and the light outlet 313 are both connected to the housing cavity 311. The light inlet 312 and the light outlet 313 may be located on different sides of the housing 31. Light may enter the housing cavity 311 through the light inlet 312, pass through the refractive element 34, and exit the refractive device 30 through the light outlet 313. The refractive element 34 may be used to change the propagation direction of light. The refractive element 34 may be a structural component such as a reflector or a prism that can change the propagation direction of light. In the present embodiment, the refractive element 34 is taken as a reflector.

[0053] It is understandable that the material of the housing 31 can be plastic, metal, glass, etc. Figure 3 The shape, size, and structure of the middle housing 31 are merely schematic representations, and the positions, shapes, and sizes of the light inlet 312 and light outlet 313 are merely schematic representations and can be designed as needed. This embodiment of the present application does not limit this. In other embodiments, the refraction device 30 may also not include the housing 31.

[0054] See Figure 5 and Figure 6 The support base 33 may include a mounting portion 331, a support portion 332, and a first side 333 and a second side 334 disposed opposite each other. The first side 333 is the light incident side of the support base 33. In other words, light enters the support base 33 from the first side 333. The first side 333 and the second side 334 are arranged along a first direction Z. The mounting portion 331 is located between the first side 333 and the second side 334.

[0055] The first elastic member 321 connects the refractive element 34 to the support base 33, and the second elastic member 322 connects the refractive element 34 to the support base 33. Exemplarily, the support base 331 may include a first wall 335 and a second wall 336, with the first wall 335 and the second wall 336 arranged along the second direction Y. The mounting portion 331 is located between the first wall 335 and the second wall 336. One end 3211 of the first elastic member 321 is fixedly connected to the first wall 335, and the other end 3212 of the first elastic member 321 is fixedly connected to the refractive element 34. It is understood that one end 3211 of the first elastic member 321 is fixedly connected to the inner side of the first wall 335, and the other end 3212 of the first elastic member 321 is located between the mounting portion 331 and the refractive element 34. One end 3221 of the second elastic member 322 is fixedly connected to the second wall 336, and the other end 3222 of the second elastic member 322 is fixedly connected to the refractive element 34. It is understood that one end 3221 of the second elastic member 322 is fixedly connected to the inner side of the second wall 336, and the other end 3222 of the second elastic member 322 is located between the mounting portion 331 and the refractive element 34. The present embodiment does not limit the specific structure of the first elastic member 321 and the second elastic member 322, and they can be configured as needed. Both the first elastic member 321 and the second elastic member 322 are structural members capable of deformation. By providing the first elastic member 321 and the second elastic member 322, the refractive element 34 is mounted to the support base 33, which helps improve the optical performance of the camera module. When there is only one elastic member, the ends of the elastic member can be fixedly connected to the first wall 335 and the second wall 336, respectively, and the middle portion of the elastic member can be fixedly connected to the refractive element 34.

[0056] The support portion 332 is fixedly connected to an edge of the mounting portion 331 near the second side 334. As will be understood, the support portion 332 protrudes from the surface of the mounting portion 331. The support portion 332 and the mounting portion 331 are arranged along the third direction X, enclosing a mounting space 338. The diffractive element 34 is positioned in the mounting space 338. The support portion 332 is used to stop the diffractive element 34. For example, when the support base 33 moves along the third direction X, or when the support base 33 stops moving along the first direction Z, the support portion 332 stops the diffractive element 34. The support portion 332 can also abut the diffractive element 34 in other situations.

[0057] It is understandable that the support portion 332 and the refractive element 34 may abut against each other to stop the refractive device 30 when it leaves the factory, or there may be a gap between the support portion 332 and the refractive element 34 when the refractive device 30 leaves the factory and the support portion 332 and the refractive element 34 may abut against each other to stop the movement when relative movement occurs.

[0058] See Figure 3 、 Figure 4 、 Figure 5 and Figure 7 , Figure 7 for Figure 3 The cross-sectional view of the partial structure shown is at AA. It can be understood that Figure 7 The structure does not include Figure 3 The housing 31 is disposed in the housing 31. The refractive element 34 may include a first portion 341 and a second portion 342. The first portion 341 corresponds to the mounting portion 331 in the first direction Z, and the second portion 342 is staggered relative to the mounting portion 331 in the first direction Z. That is, at least a portion of the structure of the second portion 342 corresponds to the support portion 332. This allows the support portion 332 to abut against the refractive element 34 when the support seat 33 moves in the third direction X, or when the support seat 33 stops moving in the first direction Z, providing support for the refractive element 34. In other words, the first portion 341 is above the mounting portion 331, and the second portion 342 is above the support portion 332. It is understood that the projection of the first portion 341 on a plane perpendicular to the first direction Z (i.e., the plane containing the third direction X and the second direction Y) overlaps with the projection of the mounting portion 331 on a plane perpendicular to the first direction Z, and the projection of the second portion 342 on a plane perpendicular to the first direction Z at least partially overlaps with the projection of the support portion 332 on a plane perpendicular to the first direction Z. It is understood that the first portion 341 and the second portion 342 can be an integrally formed structure.

[0059] The support portion 332 and the mounting portion 331 can be integrally formed. The support portion 332 and the mounting portion 331 can be integrally formed by injection molding, thereby enhancing the structural strength of the support base 33, simplifying the manufacturing process, and reducing costs. The support portion 332 and the mounting portion 331 can also be separate components that are assembled into a single piece by gluing, welding, screws, or snaps. The support portion 332 and the mounting portion 331 can be made of plastic, for example.

[0060] It is understandable that when the refraction device 30 falls and falls along the third direction X or the first direction Z, the first elastic member 321 and the second elastic member 322 will produce elastic deformation, causing the refraction element 34 to deviate from the preset position after falling, affecting the imaging effect of the camera module.

[0061] In the embodiment of the present application, by providing a support portion 332, when the refraction device 30 falls along the third direction X or falls along the first direction Z and stops falling, the support portion 332 abuts the refraction element 34, providing support for the refraction element 34. This prevents the refraction element 34 from falling or shaking, which could cause elastic-plastic deformation of the combination formed by the refraction element 34, the first elastic member 321, the second elastic member 322, and the like, thereby affecting the imaging quality of the camera module. If the support portion 332 is not provided, when the refraction device 30 falls along the third direction X or falls along the first direction Z and stops falling, the refraction element 34 falls or shakes along the inclined surface 3312 of the mounting portion 331, causing deformation of the elastic member, causing the refraction element 34 to deviate from the preset position. This could affect the imaging quality of the camera module when the refraction device 30 is used to capture images after the fall. The refraction device 30 in the embodiment of the present application has high structural stability and excellent optical performance.

[0062] See Figure 4 In some embodiments, a recess 3311 may be provided at one end of the mounting portion 331 near the second side 334 to facilitate lightweighting of the support base 33. The number of recesses 3311 may be one, two, or three, and is not limited in this embodiment of the present application. When there are at least two recesses 3311, the at least two recesses 3311 are spaced apart.

[0063] See Figure 5 and Figure 6 The mounting portion 331 may have an inclined surface 3312, and the inclined surface 3312 may be parallel to the surface of the refractive element 34. In other embodiments, the mounting portion 331 may not include the inclined surface 3312, and the structure of the mounting portion 331 may be configured as needed, which is not limited in this embodiment of the present application.

[0064] In some embodiments, a gap may be provided between the refractive element 34 and the support portion 332. To prevent the refractive device 30 from falling, the refractive element 34 and the support portion 332 may be spaced apart so that a gap is provided between them, whether the refractive device 30 is operating or not. It is understood that when the refractive element 34 is installed on the support base 33, spacing the refractive element 34 and the support portion 332 helps prevent the refractive element 34 from colliding with the support portion 332 during installation, thereby preventing damage to the refractive element 34, damaging the refractive element 34, or affecting the imaging quality of the camera module. By spacing the refractive element 34 and the support portion 332, the refractive element 34 is less likely to collide with the support portion 332 when installed on the support base 33, thereby improving the installation efficiency and installation yield of the refractive element 34 and preventing damage to the refractive element 34.

[0065] Understandably, the gap between the refractive element 34 and the support portion 332 should not be too large. If the gap between the refractive element 34 and the support portion 332 is too large, the support portion 332 will be unable to contact and support the refractive element 34 and provide support for the refractive element 34 when the refractive device 30 falls along the third direction X or falls along the first direction Z and stops falling. This will cause the elastic member to deform, causing the refractive element 34 to deviate from the preset position after falling. Alternatively, the refractive element 34 may cause the elastic member to deform significantly before the support portion 332 can contact and provide support for the refractive element 34. This will still cause the refractive element 34 to deviate from the preset position after falling, affecting the imaging quality of the camera module.

[0066] For example, the spacing between the refractive element 34 and the support portion 332 can be less than or equal to 0.5 mm, which helps prevent the refractive element 34 from colliding with the support portion 332 during installation, causing damage to the refractive element 34, thereby reducing the installation efficiency and installation yield of the refractive element 34 and affecting the imaging quality of the camera module. By setting the spacing between the refractive element 34 and the support portion 332 to be less than or equal to 0.5 mm, the spacing between the refractive element 34 and the support portion 332 is small. When the refractive device 30 falls in the third direction X or falls in the first direction Z and stops falling, the support portion 332 can support the refractive element 34, provide support force for the refractive element 34, and prevent deformation of the elastic member. For example, the spacing between the refractive element 34 and the support portion 332 can be 0.4 mm, 0.3 mm, 0.2 mm, or 0.1 mm. In other embodiments, the spacing between the refractive element 34 and the support portion 332 can also be greater than 0.5 mm, and this embodiment of the present application is not limited to this.

[0067] In other embodiments, no gap may be provided between the refractive element 34 and the support portion 332, that is, the support portion 332 always abuts against and supports the refractive element 34. Specific configurations may be made as needed. For example, a protective structure may be provided to protect the refractive element 34 to prevent damage to the refractive element 34 during installation. This is not limited in the present embodiment.

[0068] See Figure 4 and Figure 5 In some embodiments, a surface 3321 of the support portion 332 facing the refractive element 34 is parallel to a surface 343 of the refractive element 34 facing the support portion 332. It is understood that the surface 3321 of the support portion 332 facing the refractive element 34 and the surface 343 of the refractive element 34 facing the support portion 332 are arranged correspondingly. By arranging the surface 3321 of the support portion 332 facing the refractive element 34 to be parallel to the surface 343 of the refractive element 34 facing the support portion 332, the contact area between the refractive element 34 and the support portion 332 can be increased during a fall. When the refractive device 30 falls along the third direction X or falls along the first direction Z and stops falling, the support portion 332 can provide sufficient and stable support for the refractive element 34, thereby improving the structural stability of the refractive device 30.

[0069] See Figure 5 and Figure 6 , the number of the support portion 332 can be one. The support portion 332 can be located in the middle area of ​​the edge of the mounting portion 331 close to the second side 334. It can be understood that the support portion 332 corresponds to the middle position of the edge of the refractive element 34. When the refractive element 34 is mounted to the supporting seat 33, the support portion 332 corresponds to the middle area of ​​the edge of the refractive element 34, which is conducive to providing a balanced support force for the refractive element 34, and avoids the situation where the support portion 332 deviates from the middle area of ​​the refractive element 34, the support portion 332 cannot provide a balanced support force for the refractive element 34, causing the refractive element 34 to tilt, thereby affecting the imaging effect of the camera module.

[0070] In some embodiments, when the number of support portions 332 is one, the length of the support portion 332 (the length of the support portion 332 can be understood as the size of the support portion 332 in the second direction Y) can be longer. For example, the two ends of the support portion 332 in the second direction Y can be flush with the two sides of the refractive element 34 in the second direction Y, respectively, which is conducive to providing stable support for the refractive element 34 and improving the structural stability of the refractive device 30.

[0071] In some embodiments, the number of support portions 332 can be at least two, for example, the number of support portions 332 can be two, three, four or five, etc. At least two support portions 332 can be evenly spaced along the second direction Y, which is beneficial to provide balanced support force for the refractive element 34 and improve the structural stability of the refractive device 30.

[0072] Referring to Figure 6 In some embodiments, the thickness of the support portion 332 is greater than or equal to 0.2 mm. The thickness of the support portion 332 can be understood as the dimension of the support portion 332 in the first direction Z. For example, the thickness of the support portion 332 can be 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, or 1.5 mm, etc. By setting the thickness of the support portion 332 to be greater than or equal to 0.2 mm, the structural strength of the support portion 332 is improved, sufficient support force is provided for the light folding element 34, and the structural stability of the light folding device 30 is improved. In other embodiments, the thickness of the support portion 332 can also be less than 0.2 mm, which is not limited in the embodiments of the present application.

[0073] In some embodiments, the length of the support portion 332 is greater than or equal to 1 mm. The length of the support portion 332 can be understood as the dimension of the support portion 332 in the second direction Y. For example, the length of the support portion 332 can be 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 3 mm, 4 mm, or 5 mm, etc. By setting the length of the support portion 332 to be greater than or equal to 1 mm, the contact area of the support portion 332 with the light folding element 34 is improved, sufficient support force is provided for the light folding element 34, and the structural stability of the light folding device 30 is improved. In other embodiments, the length of the support portion 332 can also be less than 1 mm, which is not limited in the embodiments of the present application.

[0074] In some embodiments, the width of the support portion 332 is greater than or equal to 1 mm. The width of the support portion 332 can be understood as the dimension of the support portion 332 in the third direction X. For example, the width of the support portion 332 can be 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, 2.0 mm, 2.2 mm, 2.4 mm, 2.6 mm, 3 mm, 4 mm, or 5 mm, etc. By setting the width of the support portion 332 to be greater than or equal to 1 mm, the contact area of the support portion 332 with the light folding element 34 is improved, sufficient support force is provided for the light folding element 34, and the structural stability of the light folding device 30 is improved. In addition, by setting the width of the support portion 332 to be greater than or equal to 1 mm, the support portion 332 has sufficient size in the third direction X, so that the light folding element 34 does not separate from the support portion 332 in the third direction X during the falling of the light folding device 30. In other embodiments, the width of the support portion 332 can also be less than 1 mm, which is not limited in the embodiments of the present application.

[0075] It can be understood that the length of the support portion 332 can be greater than the width of the support portion 332, for example, the length of the support portion 332 can be 1.5 mm, and the width of the support portion 332 can be 1.1 mm; the length of the support portion 332 can be equal to the width of the support portion 332, for example, the length of the support portion 332 and the width of the support portion 332 can both be 1.3 mm; the length of the support portion 332 can be less than the width of the support portion 332, for example, the length of the support portion 332 can be 1.3 mm, and the width of the support portion 332 can be 1.7 mm.

[0076] It is understood that the shape of the support portion 332 can be a regular shape such as a square, or it can be any irregular shape. When the shape of the support portion 332 is irregular, the thickness of the support portion 332 is the maximum dimension of the support portion 332 in the first direction Z. The length of the support portion 332 is the maximum dimension of the support portion 332 in the second direction Y. The width of the support portion 332 is the maximum dimension of the support portion 332 in the third direction X.

[0077] like Figure 6 and Figure 8 As shown, Figure 8 for Figure 4 A side view of a partial structure of the refraction device 30 is shown, Figure 8 The side view is from Figure 4 The viewing angle of the side where the middle support portion 332 is located. The area of ​​the surface 3321 of the support portion 332 facing the refractive element 34 is the first area, and the area of ​​the projection of the second portion 342 on the plane where the support portion 332 is located is the second area. The ratio of the first area to the second area is greater than or equal to 5%. For example, the ratio of the first area to the second area can be 10%, 15%, 20%, 25%, 30%, 35%, 45%, 55% or 70%, etc. By setting the ratio of the first area to the second area to be greater than or equal to 5%, it is beneficial to increase the contact area between the support portion 332 and the refractive element 34 when falling, provide sufficient supporting force for the refractive element 34, and improve the structural stability of the refractive device 30. In other embodiments, the ratio of the first area to the second area can also be less than 5%, and the embodiments of the present application are not limited to this.

[0078] The angles between adjacent surfaces of the support portion 332 may be chamfered, for example, see Figure 6 and Figure 8The support portion 332 includes an arcuate segment 3322, connecting two adjacent side surfaces of the support portion 332 via the arcuate segment 3322. In other words, the arcuate segment 3322 can be located at a corner of the support portion 332. It is understood that if the corners of the support portion 332 are sharp, the support portion 332 may damage the refractive element 34 during installation. Providing the arcuate segment 3322 at the corners of the support portion 332 makes the corners of the support portion 332 smoother, preventing damage to the refractive element 34 during installation, thereby improving installation efficiency and yield.

[0079] Taking the shape of the supporting portion 332 as an example, the shape of the supporting portion 332 may be a square or a rectangle. Figure 6 and Figure 8 Taking the rectangular support portion 332 as an example, by providing arc segments 3322 at two corners of the support portion 332 away from the mounting portion 331 , the edge of the support portion 332 is smoothed, thereby preventing the support portion 332 from damaging the refraction element 34 when the refraction element 34 is in operation.

[0080] See Figure 9 , Figure 9 Schematic diagrams of different structures of the support portion 332. The shape of the support portion 332 can also be a partial structure of a circle (one-third circle, semicircle, or two-thirds circle, etc.), a partial structure of an ellipse (one-third ellipse, semi-ellipse, or two-thirds ellipse, etc.), a trapezoid, or a triangle, etc. The support portion 332 can be of any shape, and the embodiment of the present application does not limit the shape of the support portion 332.

[0081] When the support portion 332 is a circular partial structure or an elliptical partial structure, the support portion 332 includes a straight edge and an arcuate edge. The straight edge of the support portion 332 is fixedly connected to the mounting portion 331, and the arcuate edge of the support portion 332 is a smooth edge, which can prevent the support portion 332 from damaging the refractive element 34 when installing the refractive element 34.

[0082] When the support portion 332 is trapezoidal, the long side of the trapezoid is parallel to the short side. The long side of the trapezoid can be fixedly connected to the mounting portion 331 to increase the contact and connection area between the support portion 332 and the mounting portion 331, thereby increasing the strength and reliability of the connection between the support portion 332 and the mounting portion 331. In other embodiments, the short side of the trapezoid can also be fixedly connected to the mounting portion 331. When the support portion 332 is trapezoidal, the corners of the support portion 332 can be provided with curved sections to smooth the edges of the support portion 332 and prevent the support portion 332 from damaging the refractive element 34 when the refractive element 34 is in use.

[0083] When the support portion 332 is triangular, arc segments may be provided at the corners of the support portion 332 to make the edge of the support portion 332 smooth, thereby preventing the support portion 332 from damaging the refraction element 34 .

[0084] See again Figure 4 、 Figure 5 and Figure 6 The support base 33 may include a buffer member 35. The buffer member 35 may be located between the support portion 332 and the diffractive element 34. For example, the buffer member 35 may be fixed to the surface 3321 of the support portion 332. After the diffractive element 34 is mounted on the support base 33, the buffer member 35 is located between the support portion 332 and the diffractive element 34. The buffer member 35 can provide a buffering effect. When the diffractive device 30 falls along the third direction X or falls along the first direction Z and stops falling, the diffractive element 34 strikes the buffer member 35, causing the buffer member 35 to deform, releasing the impact force and preventing damage to the diffractive element 34.

[0085] The buffer member 35 can be located in the middle area of ​​the support portion 332, which helps provide uniform buffering force for the refractive element 34 and improve the structural stability of the refractive device. In other embodiments, the buffer member 35 can also be located at the edge of the support portion 332. The embodiment of the present application does not limit the position of the buffer member 35. The number of buffer members 35 can be one, or two, three, four, or five, etc., with multiple buffer members 35 distributed on the support portion 332. The embodiment of the present application does not limit the shape, area, etc. of the buffer member 35, and can be set as needed.

[0086] In some embodiments, the cushioning member 35 may be made of a material such as foam or soft rubber. When the cushioning member 35 is made of soft rubber, the elastic modulus of the soft rubber is less than or equal to 10 GPa, making the soft rubber sufficiently flexible to effectively cushion the refractive element 34. The soft rubber may be acrylic or other colloids, and the present embodiment does not limit the material of the soft rubber.

[0087] See Figure 4 and Figure 5 In some embodiments, the buffer member 35 can be located between the elastic member and the diffractive element 34. The buffer member 35 can be fixed to the elastic member. After the diffractive element 34 is mounted on the support base 33, the buffer member 35 is located between the elastic member and the diffractive element 34. For example, the buffer member 35 can be located between the first elastic member 321 and the diffractive element 34, or between the second elastic member 322 and the diffractive element 34. For example, the buffer member 35 can be located between one end 3211 of the first elastic member 321 and the diffractive element 34, or between one end 3221 of the second elastic member 322 and the diffractive element 34.

[0088] In the embodiment of the present application, a buffer member 35 is provided between the elastic member and the refractive element 34. When the refractive device 30 falls in the second direction Y, the buffer member 35 acts as a buffer, preventing the elastic member from striking the refractive element 34 and damaging the refractive element 34. Furthermore, if the buffer member 35 is not provided between the elastic member and the refractive element 34, the elastic member will deform when the refractive device 30 falls in the second direction Y, causing the refractive element 34 to deviate from the preset position. This could affect the image quality of the camera module when the refractive device 30 is photographed after the fall.

[0089] The buffer member 35 can be disposed in the middle region of the refractive element 34 to provide uniform buffering force to the refractive element 34 and improve the structural stability of the refractive device. In other embodiments, the buffer member 35 can also be disposed at the edge of the refractive element 34. The present embodiment does not limit the position of the buffer member 35. The number of buffer members 35 can be one, two, three, four, or five, and multiple buffer members 35 can be distributed on the first elastic member 321 or the second elastic member 322. The present embodiment does not limit the shape, area, etc. of the buffer member 35 and can be set as needed.

[0090] See Figure 10 and Figure 11 , Figure 10 for Figure 4 A side view of a partial structure of the refractive device shown, Figure 11 for Figure 4 Another side view of a partial structure of the diopter device shown, Figure 10 In the figure, the refracting element 34 is viewed from the side facing away from the mounting portion. Figure 11 The middle part is a view on the side where the second wall 336 is located. The refraction device 30 may include a drive assembly 36. The drive assembly 36 can be used to drive the bearing seat 33 and the refraction element 34 to move, thereby achieving anti-shake and improving the imaging quality of the camera module.

[0091] In some embodiments, the driving assembly 36 may include a coil 361 and a magnetic member 362, and the coil 361 and the magnetic member 362 are arranged correspondingly. The coil 361 and the magnetic member 362 may be located between the housing 31 and the bearing seat 33. For example, the coil 361 may be fixed to the housing 31 (see Figure 3 ), the magnetic member 362 can be fixed to the outer wall of the support base 33. When the magnetic member 362 is fixed to the outer wall of the support base 33, the outer wall of the support base 33 can be provided with a groove, and the magnetic member 362 is embedded in the groove of the outer wall of the support base 33, which helps to reduce the space occupied by the drive assembly 36 in the refraction device 30 and facilitates the miniaturization of the refraction device 30. The coil 361 and the magnetic member 362 can also be correspondingly arranged at other locations on the housing 31 and the support base 33, and this embodiment of the present application is not limited to this.

[0092] When the coil 361 is energized, the magnetic member 362 moves under the action of the magnetic field of the coil 361 , and the magnetic member 362 drives the supporting seat 33 and the refractive element 34 to move, thereby achieving anti-shake of the camera module, which is beneficial to improving the imaging quality of the camera module.

[0093] It is understandable that the number of coils 361 and magnetic parts 362 can be one, two, three, four or five, etc., and the embodiment of the present application does not limit the number of coils 361 and magnetic parts 362. For example, when the number of coils and magnetic parts 362 is three, one coil 361 and magnetic part 362 can be correspondingly arranged on the outside of the first wall 335, one coil 361 and magnetic part 362 can be correspondingly arranged on the outside of the second wall 336, and another coil 361 and magnetic part 362 can be correspondingly arranged on the outside of the rear wall 337. By providing multiple coils 361 and magnetic parts 362, sufficient driving force can be provided for the movement of the supporting seat 33 and the refractive element 34, and it is beneficial to provide more degrees of freedom of movement for the movement of the supporting seat 33 and the refractive element 34. The supporting seat 33 and the refractive element 34 can move or rotate in different directions as needed to achieve anti-shake. For example, the supporting base 33 and the refractive element 34 can rotate around a third direction to achieve anti-shake, and the supporting base 33 and the refractive element 34 can also swing up and down around the third direction to achieve anti-shake.

[0094] In other embodiments, the driving component 36 may also be a memory metal alloy or other driving structures, which is not limited in the embodiment of the present application and can be set as needed.

[0095] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
