Technical Field

[0001] The present application relates to the technical field of terminal equipment, and in particular to an electronic device. Background Art

[0002] With the development of science and technology, not only higher requirements are placed on the functions of electronic devices such as mobile phones and tablets, but the appearance of electronic devices is also developing in the direction of being lighter and thinner.

[0003] Taking a mobile phone as an example, the camera module of a mobile phone is usually installed on the middle frame. Among them, the camera module includes a lens assembly and a filter assembly and a photosensitive chip assembly which are sequentially mounted on the light-emitting side of the lens assembly. In order to reduce the thickness of the entire machine, an avoidance opening is usually opened on the middle frame. Taking the front camera as an example, in the camera module, the lens assembly mainly occupies the installation space between the middle frame and the screen, and the photosensitive chip assembly and a filter assembly of part thickness extend into the avoidance opening to reduce the thickness space occupied by the camera module.

[0004] However, as the planar size of the camera module gradually increases, the area of ​​the avoidance opening on the middle frame also gradually increases, resulting in a decrease in the strength of the middle frame. Summary of the invention

[0005] The present application provides an electronic device, wherein a camera module of the electronic device occupies a small space, which satisfies the requirement of making the entire device thin and light while reducing the impact of the installation of the camera module on a middle frame and increasing the strength of the middle frame.

[0006] The present application provides an electronic device, including a middle frame and a camera module, wherein the middle frame includes a frame portion and a support plate connected to the frame portion, an opening is provided on the support plate, and the camera module is installed on the middle frame and corresponds to the opening;

[0007] The camera module includes a lens assembly and a dimming conversion assembly, wherein the dimming conversion assembly is arranged on the light-emitting side of the lens assembly and extends into the opening; at least a portion of the circumferential area of ​​the edge of the dimming conversion assembly has an inner concave portion, and the edge of the inner concave portion is located on the inner side of the edge of the lens assembly;

[0008] The recessed portion is located on a side of the dimming conversion component away from the lens component, and occupies at least part of the thickness of the dimming conversion component; a clearance space is formed between the edge of the recessed portion and the edge of the lens component, and the inner edge of the opening has a reinforcement portion, which extends into the clearance space.

[0009] The electronic device provided by the present application has an opening formed in the support plate of the middle frame, and the camera module is installed corresponding to the opening. By making at least part of the thickness of the light modulation conversion component of the camera module extend into the opening, this part of the thickness of the light modulation conversion component does not occupy the installation space between the middle frame and the rear cover (display panel), which can reduce the thickness of the whole machine and is beneficial to the thinning of the electronic device. Among them, by providing at least part of the area on the circumferential edge of the light modulation conversion component with a concave portion, the edge of the concave portion is retracted inside the edge of the lens module, and a clearance space is formed between the edge of the concave portion and the edge of the lens module. By providing a reinforcing portion at the position corresponding to the concave portion on the inner edge of the opening, the reinforcing portion extends into the clearance space to reduce the area of the opening region surrounded by the opening, increase the coverage area of the support plate, increase the structural strength of the middle frame, and improve the reliability of the camera module and the electronic device.

[0010] In a possible implementation manner, the light modulation conversion component includes a filter component and an image sensor component. The filter component and the image sensor component are stacked in sequence on the light-emitting side of the lens module, and both the image sensor component and the filter component extend into the opening.

[0011] Among them, the concave portion is at least provided on the image sensor component.

[0012] The filter component is mounted on the light-emitting side of the lens module, and the image sensor component is connected to the side of the filter component away from the lens module. By providing at least a concave portion on the image sensor component, the reinforcing portion extending from the inner edge of the opening on the support plate is at least correspondingly located outside the circumferential side of the image sensor component to ensure that the light modulation conversion component can extend into the opening region surrounded by the reinforcing portion.

[0013] In a possible implementation manner, the edge of the filter component is flush with the edge of the lens module, and at least part of the area on the circumference of the edge of the image sensor component has a concave portion.

[0014] The reinforcing portion includes a stepped portion connected to the inner edge of the opening. In the thickness direction of the support plate, the stepped portion is located on the part of the support plate away from the lens module.

[0015] The edge of the support frame of the filter component is flush with the edge of the lens module. By providing a concave portion on the edge of the substrate of the image sensor component, a clearance space is formed between the edge of the concave portion of the substrate and the edge of the lens module. In the thickness direction of the support plate, the part of the inner edge of the opening corresponding to the support frame is located outside the side wall of the lens module, and the part of the inner edge of the opening corresponding to the concave portion of the substrate extends inward to form a stepped portion, and this stepped portion extends into the clearance space to form a reinforcing portion.

[0016] In a possible implementation, at least a partial area in the circumferential direction of the edge of the image sensor assembly has a first concave portion, and at least a partial area in the circumferential direction of the edge of the filter component has a second concave portion. The second concave portion corresponds to the first concave portion, and the first concave portion and the second concave portion together form a concave portion;

[0017] Wherein, a first relief space is formed between the edge of the first concave portion and the edge of the lens assembly, and a second relief space is formed between the edge of the second concave portion and the edge of the lens assembly. The reinforcing portion extends into the first relief space and the second relief space.

[0018] By providing a first concave portion on the circumferential edge of the substrate of the image sensor assembly and a second concave portion on the circumferential edge of the support frame of the filter component, the first concave portion and the second concave portion together form a concave portion. A first relief space is formed between the edge of the first concave portion and the edge of the lens assembly, and a second relief space is formed between the edge of the second concave portion and the edge of the lens assembly. In this way, the reinforcing portion extending from the inner edge of the opening on the support plate can include a portion extending into the first relief space and a portion extending into the second relief space, which can increase the thickness of the reinforcing portion and improve the structural strength of the support plate. Among them, the second concave portion should correspond to the first concave portion so that the first concave portion can pass through the opening area surrounded by the portion of the reinforcing portion corresponding to the second concave portion and extend into the opening area surrounded by the portion of the reinforcing portion corresponding to the first concave portion.

[0019] In a possible implementation, the orthographic projection of the image sensor assembly on the filter component completely covers the filter component. The two side surfaces of the reinforcing portion are respectively flush with the two side surfaces of the support plate, and the end surfaces of the side walls of the reinforcing portion facing the dimming conversion component are flush.

[0020] By making the edge of the second concave portion flush with the edge of the first concave portion, or making the edge of the second concave portion retract inside the edge of the first concave portion, the projection of the image sensor assembly on the filter component completely covers the filter component, and the cross-sectional area of the second relief space is greater than or equal to the cross-sectional area of the first relief space. Since the substrate of the image sensor assembly needs to pass through the opening area surrounded by the portion extending into the second relief space of the reinforcing portion, the inner edge of the opening can extend inward as a whole in the thickness direction of the substrate to form the reinforcing portion, which can increase the thickness of the reinforcing portion and improve the structural strength of the support plate. Moreover, the length of the portion of the reinforcing portion extending into the second relief space is the same as the length of the portion of the reinforcing portion extending into the first relief space, and the end surfaces of the reinforcing portion facing the dimming conversion component are flush.

[0021] In a possible implementation, the edge of the first concave portion is located inside the edge of the second concave portion. The reinforcing portion includes a first reinforcing portion and a second reinforcing portion. The first reinforcing portion extends into the first relief space and is located on the part of the support plate away from the lens assembly, and the second reinforcing portion extends into the second relief space and is located on the part of the support plate close to the lens assembly;

[0022] Wherein, the extension length of the first reinforcing portion is greater than that of the second reinforcing portion, and the first reinforcing portion has a stepped surface facing the filter component.

[0023] By making the first concave portion retract inside the second concave portion, the edge of the first concave portion is located inside the edge of the second concave portion, the cross-sectional area of the first relief space is greater than that of the second relief space. Correspondingly, the reinforcing portion includes a first reinforcing portion extending into the first relief space and a second reinforcing portion extending into the second relief space respectively. By making the extension length of the first reinforcing portion greater than that of the second reinforcing portion, the end of the first reinforcing portion extends out of the second reinforcing portion, and a stepped surface facing the filter component is formed between the first reinforcing portion and the second reinforcing portion. In this way, the extension length of the reinforcing portion is increased, the area of the opening is reduced, and the structural strength of the support plate is improved.

[0024] In a possible implementation, the concave portion covers at least one side of the dimming conversion component.

[0025] By providing a concave portion on at least one side of the dimming conversion component, and the concave portion extends to cover the entire area of the side, in this way, the reinforcing portion formed by the inner edge of the opening can cover the entire area of the inner wall of the corresponding side of the opening, the coverage area of the reinforcing portion can be increased, the opening area of the opening can be reduced, and the structural strength of the support plate can be improved.

[0026] In a possible implementation, the concave portion covers at least the opposite sides of the dimming conversion component.

[0028] In a possible implementation, the concave portion is provided corresponding to the corner of the dimming conversion component, and at least one corner of the dimming conversion component is provided with a concave portion.

[0029] By providing a concave portion at the corner of the dimming conversion component, correspondingly, the corner of the inner edge of the opening on the support plate extends inward to form a reinforcing portion, so as to reduce the area of the opening, increase the coverage area of the support plate, and enhance the structural strength of the support plate.

[0030] In a possible implementation, the camera module further includes a protective cover, the protective cover wraps the side walls of the dimming conversion component and the lens assembly, and the protective cover has a recessed portion corresponding to the concave portion.

[0031] By wrapping a protective cover around the outer sides of the dimming conversion component and the lens component sidewalls, the protective cover can improve the sealing performance of the camera module, prevent foreign objects in the external environment from entering the dimming conversion component, and protect the performance of the dimming conversion component. Among them, by providing a recessed portion at a position on the protective cover corresponding to the concave portion of the dimming conversion component, the recessed portion can provide space for the strengthening portion of the inner edge of the opening and enable the protective cover to pass through the opening area surrounded by the strengthening portion.

[0032] In a possible implementation manner, the protective cover is connected to the middle frame.

[0033] By connecting the protective cover to the middle frame, the camera module is mounted on the middle frame.

[0034] In a possible implementation manner, the camera module further includes a bracket, the bracket is sleeved on the sidewall of the lens component, and the bracket is connected to the middle frame.

[0035] By sleeving a bracket on the sidewall of the lens component, the bracket is fixedly connected to the middle frame, and the camera module is mounted on the middle frame through the bracket. Among them, the bracket can be directly sleeved on the sidewall of the lens component, or the bracket is sleeved outside the protective cover wrapped outside the sidewall of the lens component.

The side of the connection section of the FPC facing the support plate is its first side. By making the distance between at least some sections of the first side of the FPC and the support plate greater than the distance between the lens assembly and the support plate, the distance between at least some sections of the connection section and the support plate is greater than or equal to the distance between the lens assembly and the support plate. The connection section increases the distance between the concave portion at the edge of the dimming conversion component and the FPC located outside the lens assembly, provides space for the extension of the strengthening portion at the inner edge of the opening on the support plate, increases the extension length of the strengthening portion, reduces the area of the opening region surrounded by the strengthening portion, increases the coverage area of the support plate, and improves the structural strength of the middle frame.

The FPC outside the corresponding side of the lens assembly can provide extra space, increasing the distance between the outer edge of the concave portion on the corresponding side of the dimming conversion component and the connection section of the FPC.

[0078] The terms used in the implementation manners part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application.

[0079] With the continuous progress of technology, the shooting function has gradually become an essential feature of terminal devices such as mobile phones, tablet computers, laptop computers, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), smart wearable devices, point of sales (POS) terminals, in-vehicle devices, augmented reality (AR) / virtual reality (VR) devices, etc.

[0080] Figure 1 Structural schematic diagram of the electronic device provided by the embodiment of this application; Figure 2 is Figure 1 partial exploded view of. Refer to Figure 1 and Figure 2 As shown in, taking a mobile phone as an example, the electronic device 100 of this application will be described. It should be understood that the electronic device 100 in this embodiment includes but is not limited to a mobile phone, and the electronic device 100 can also be the above-mentioned terminal devices such as tablet computers, laptop computers, UMPCs, netbooks, PDAs, POS terminals, in-vehicle devices, AR / VR devices, etc.

[0081] Refer to Figure 1 and Figure 2 As shown in, the electronic device 100 may include a housing, a display panel 4, a camera module 1, and a circuit board 5. The housing surrounds the back and sides of the electronic device 100, the display panel 4 is installed on the housing, the display panel 4 and the housing together enclose the accommodation space of the electronic device 100, and both the camera module 1 and the circuit board 5 are installed in this accommodation space. In addition, devices such as a microphone, a speaker, or a battery may also be provided in the accommodation space.

[0082] Combined with Figure 1 As shown in, it shows that the camera module 1 is located in the area near the edge at the top of the housing. It can be understood that the position of the camera module 1 is not limited to Figure 1 the position shown in.

[0083] Refer toFigure 2 As shown, the housing may include a rear cover 3 and a middle frame 2, and the camera module 1 may be disposed on the middle frame 2. A light-transmitting hole 31 is provided on the rear cover 3. Taking the camera module 1 as a rear camera as an example, the camera module 1 collects external ambient light through the light-transmitting hole 31 on the rear cover 3. Among them, the light-incident surface of the camera module 1 and the light-transmitting hole 31 are oppositely arranged. The external ambient light passes through the light-transmitting hole 31 and irradiates onto the light-incident surface of the camera module 1. The light-incident surface of the camera module 1 is used to collect external ambient light, and the camera module 1 is used to convert the optical signal into an electrical signal to realize its shooting function.

[0084] The camera module 1 may also be a front camera. At this time, the light-incident surface of the camera module 1 faces the display panel 4. A light-transmitting portion (not shown) is provided on the display panel 4 at a position directly opposite to the light-incident surface of the camera module 1. The external ambient light passes through the light-transmitting portion of the display panel 4 and irradiates onto the light-incident surface of the camera module 1, which will not be elaborated here.

[0085] Figure 2 It is shown that there is one camera module 1 provided in the electronic device 100. It should be noted that in practical applications, the number of camera modules 1 is not limited to one, and the number of camera modules 1 may also be two or more than two. When the number of camera modules 1 is multiple, the multiple camera modules 1 can be arranged arbitrarily in the X-Y plane. For example, the multiple camera modules 1 are arranged along the X-axis direction, or the multiple camera modules 1 are arranged along the Y-axis direction.

[0086] In addition, the camera module 1 includes but is not limited to an auto focus (AF) module, a fixed focus (FF) module, a wide-angle camera module, a telephoto camera module, a color camera module or a black-and-white camera module. The camera module 1 in the electronic device 100 may include any one of the above camera modules 1, or include two or more of the above camera modules 1. When the number of camera modules 1 is two or more, the two or more camera modules 1 can be integrated into one camera assembly.

[0087] Referring to Figure 2 As shown, the camera module 1 may be electrically connected to the circuit board 5. The circuit board 5 is, for example, the main board in the electronic device 100. As an implementation manner, the camera module 1 may be electrically connected to the main board through an electrical connector 134. For example, the camera module 1 is provided with a female seat of the electrical connector 134, and the main board is provided with a male seat of the electrical connector 134. By inserting the female seat into the male seat, the electrical connection between the camera module 1 and the main board is realized. Among them, a processor may be provided on the main board, and the processor controls the camera module 1 to capture images. When the user inputs a shooting instruction, the processor receives the shooting instruction and controls the camera module 1 to shoot the shooting object according to the shooting instruction.

[0088] In practical applications, the thickness direction of the electronic device 100 is usually used as the optical axis direction of the camera module 1 for installation and setting of the camera module 1, and an installation space is provided for the camera module 1 in the thickness direction of the electronic device 100. Taking the camera module 1 as a rear camera as an example, inside the electronic device 100, the camera module 1 is located in the space between the middle frame 2 and the rear cover 3; taking the camera module 1 as a front camera as an example, inside the electronic device 100, the camera module 1 is located in the space between the middle frame 2 and the display panel 4.

[0089] Figure 3 It is a schematic diagram of an installation structure of a camera module in the related art. Refer to Figure 3 As shown, the camera module 1 generally includes a lens assembly 11, a filter assembly 12, and an image sensor assembly 13. The filter assembly 12 and the image sensor assembly 13 are sequentially stacked on the light-emitting side of the lens assembly 11. Among them, the image sensor assembly 13 faces the middle frame 2, and the lens assembly 11 faces the rear cover 3 or the display panel 4. The camera module 1 may further include a bracket 16. The bracket 16 is sleeved on the outer side wall of the lens assembly 11, and the bracket 16 is fixedly connected to the middle frame 2, and the camera module 1 is installed on the middle frame 2 through the bracket 16.

[0090] In order to reduce the installation space occupied by the camera module 1, an opening 211 is formed on the middle frame 2, so that the image sensor assembly 13 and a part of the thickness of the filter assembly 12 extend into the opening 211. The space between the middle frame 2 and the rear cover 3 (display panel 4) is mainly used to arrange the lens assembly 11. In this way, the thickness space of the whole machine occupied by the camera module 1 itself is reduced, and further, the thickness of the whole machine can be reduced, which is beneficial to the thinning of the electronic device 100.

[0091] In addition, in order to improve the performance of the camera module 1, the planar size of the camera module 1 is gradually increased, that is, the cross-sectional area of the camera module 1 perpendicular to the optical axis direction is increased. Combining Figure 3 As shown, the planar sizes of the filter assembly 12 and the image sensor assembly 13 are synchronously increased to match the lens assembly 11. In this way, the size of the opening 211 formed on the middle frame 2 is also gradually increased.

[0092] However, as the size of the opening 211 on the middle frame 2 increases, the structural strength of the middle frame 2 decreases. The structural strength of the middle frame 2 affects the installation performance of the camera module 1, reduces the reliability of the camera module 1, and further affects the reliability of the electronic device 100.

[0093] In view of this, the electronic device provided by the embodiment of the present application has a concave portion provided at the edge of the dimming conversion component in the camera module, so that at least a part of the edge region on the side of the dimming conversion component facing the middle frame is recessed inside the lens component, and a clearance space is formed between the edge of the concave portion and the edge of the lens component. Thus, the inner edge of the opening provided on the middle frame can have a reinforcing portion extending into the clearance space. In this way, while reducing the thickness space occupied by the camera module, the size of the opening provided on the middle frame can be reduced, the structural strength of the middle frame can be increased, and the reliability of the camera module can be ensured.

[0094] Figure 4 FIG. 4 is a schematic structural diagram of the camera module provided by the embodiment of the present application mounted on the middle frame; Figure 5 is Figure 4 an exploded view of Figure 6 is Figure 5 the exploded view of the camera module in

[0095] Referring to Figure 4 as shown in FIG. 5, in the electronic device 100 of the present embodiment, the middle frame 2 includes a frame portion 22 and a support plate 21 connected to at least a part of the inner edge region of the frame portion 22. The frame portion 22 can be adapted to the contour of the electronic device 100, and the frame portion 22 surrounds the outer periphery of the electronic device 100. The display panel 4 and the rear cover 3 are respectively located on both sides of the middle frame 2, and the display panel 4 and the rear cover 3 are supported and limited by the frame portion 22. The support plate 21 is connected to the inner edge of the frame portion 22, that is, the support plate 21 is located within the region surrounded by the frame portion 22. Some components in the electronic device 100 can be mounted on the support plate 21. For example, components such as the camera module 1, the speaker, and the earpiece can be mounted on the support plate 21.

[0096] Exemplarily, the support plate 21 can be connected to the frame portion 22 on the side close to the display panel 4. The surface of the support plate 21 facing the display panel 4 can be a flat surface, and the display panel 4 can be bonded to this side surface of the support plate 21 by means of a dispensing process or the like. An installation space is formed between the support plate 21 and the rear cover 3, and components such as the camera module 1, the speaker, and the earpiece can be mounted on the surface of the support plate 21 facing the rear cover 3.

[0097] The support plate 21 can cover all of the region surrounded by the frame portion 22 (except for the regions where through holes or openings are provided on the support plate 21), or the support plate 21 only covers a part of the region surrounded by the frame portion 22. For example, the support plate 21 is only connected at the positions where the above components need to be mounted. The present embodiment does not limit this.

[0098] Referring to Figure 5As shown, in this embodiment, the camera module 1 installed in the middle frame 2 includes a lens assembly 11 and a dimming conversion component. The axial direction of the lens assembly 11 is, for example, the thickness direction of the electronic device 100. The dimming conversion component is mounted on the light-emitting side of the lens assembly 11. External ambient light enters the camera module 1 from the light-incident side of the lens assembly 11. After the light is emitted from the light-emitting side of the lens assembly 11, it enters the dimming conversion component, and the light signal is converted into an electrical signal through the dimming conversion component to realize the imaging function of the camera module 1.

[0099] Among them, for the camera module 1 located in the installation space between the support plate 21 and the rear cover 3, taking the camera module 1 as a front camera as an example, the lens assembly 11 of the camera module 1 faces the display panel 4, and the dimming conversion component faces the rear cover 3. By opening a light-transmitting hole in the support plate 21, the light-incident surface of the lens assembly 11 is located in the light-transmitting hole to facilitate the lens assembly 11 to receive the light incident from one side of the display panel 4. Taking the camera module 1 as a rear camera as an example, the lens assembly 11 of the camera module 1 faces the rear cover 3, and the dimming conversion component faces the display panel 4.

[0100] The camera module 1 is located in the installation space between the support plate 21 and the rear cover 3. In order to reduce the occupied space of the camera module 1 in its axial direction, for the front camera, the front end of the lens assembly 11 can pass through the light-transmitting hole opened in the support plate 21 to reduce the height of the camera module 1 located in the installation space; for the rear camera, an opening 211 can be opened in the support plate 21 to make at least part of the thickness of the dimming conversion component of the camera module 1 extend into the opening 211 to reduce the height of the camera module 1 located in the installation space.

[0101] In some embodiments, in the part of the electronic device 100 where the front camera is provided, there may be an installation space between the support plate 21 and the display panel 4, and the front camera can be installed in the installation space between the display panel 4 and the support plate 21. At this time, the dimming conversion component of the front camera faces the support plate 21, an opening 211 is opened in the part of the support plate 21 corresponding to the front camera, and at least part of the thickness of the dimming conversion component of the front camera extends into the opening 211.

[0102] Refer to Figure 5 As shown, in this embodiment, it mainly aims at the installation structure in which at least part of the thickness of the dimming conversion component of the camera module 1 extends into the opening 211 on the support plate 21. Among them, the camera module 1 can be a rear camera located in the installation space between the rear cover 3 and the support plate 21, or a front camera located in the installation space between the display panel 4 and the support plate 21.

[0103] As the planar size of the lens assembly 11 gradually increases, in order to avoid the opening 211 opened on the support plate 21 affecting the structural strength of the middle frame 2, refer toFigure 6 As shown, by making at least a partial area of the circumferential edge of the dimming conversion component retract inside the lens component 11, the size of the dimming conversion component is reduced, and a clearance space is formed between the edge of the dimming conversion component and the edge of the lens component 11 in the plane direction of the camera module 1 (the direction perpendicular to the axial direction of the camera module 1). In this way, the inner edge of the opening 211 on the support plate 21 can extend into the clearance space, reducing the size of the opening 211 and increasing the strength of the middle frame 2.

[0104] Specifically, by providing a concave portion 14 at the edge of the dimming conversion component, in the plane direction of the camera module 1 (the plane perpendicular to the optical axis of the camera module 1), the edge of the concave portion 14 is located inside the edge of the lens component 11, that is, the edge of the concave portion 14 retracts inside the edge of the lens component 11, and a clearance space is formed between the edge of the concave portion 14 and the edge of the lens component 11. A reinforcing portion 212 is formed on the inner edge of the opening 211 of the support plate 21. The reinforcing portion 212 extends inward from the inner side of the opening 211 and extends into the clearance space. The cross-sectional area of the opening 211 is smaller than the cross-sectional area of the lens component 11, reducing the size of the opening 211 and increasing the coverage area of the support plate 21. Thus, the structural strength of the middle frame 2 is enhanced, providing a reliable guarantee for the installation of the camera module 1.

[0105] Combined with Figure 4 As shown, when installing the camera module 1, the camera module 1 is installed on the middle frame 2 from the installation space formed between the support plate 21 and the rear cover 3 (display panel 4). The dimming conversion component of the camera module 1 faces the support plate 21, and the dimming conversion component extends into the opening 211 from the side facing away from the lens component 11. Referring to Figure 6 As shown, in order to make the dimming conversion component extend into the opening area surrounded by the reinforcing portion 212 at the inner edge of the opening 211, the concave portion 14 should be located on the side of the dimming conversion component facing away from the lens component 11, so that the side of the dimming conversion component facing away from the lens component 11 retracts inside the lens component 11, and the dimming conversion component extends into the opening area surrounded by the reinforcing portion 212 at the inner edge of the opening 211.

[0106] Among them, the concave portion 14 occupies at least a part of the thickness of the dimming conversion component, so that the clearance space formed between the edge of the concave portion 14 and the edge of the lens component 11 occupies at least a part of the thickness of the dimming conversion component. Correspondingly, the reinforcing portion 212 formed on the inner edge of the opening 211 can occupy at least a part of the thickness of the support plate 21. In addition, in the thickness direction of the dimming conversion component, in order to make more parts of the dimming conversion component extend into the opening 211, the reinforcing portion 212 can be flush with the surface of the support plate 21 facing away from the lens component 11.

[0107] Figure 7a It is a cross-sectional view of an installation structure of a camera module provided by an embodiment of the present application;Figure 7b A cross-sectional view of another installation structure of the camera module provided by the embodiment of the present application; Figure 7c A cross-sectional view of the third installation structure of the camera module provided by the embodiment of the present application.

[0108] Referring to Figure 7a As shown, the dimming conversion component includes a filter component 12 and an image sensor component 13. The filter component 12 and the image sensor component 13 are stacked in sequence on the light-emitting side of the lens component 11. The filter component 12 is mounted on the light-emitting side of the lens component 11, and the image sensor component 13 is connected to the side of the filter component 12 facing away from the lens component 11. Among them, the image sensor component 13 extends into the opening 211. For example, the image sensor component 13 is within the thickness range of the support plate 21, or a part or all of the thickness of the image sensor component 13 passes through the opening 211 and extends outside the support plate 21, and at least a part of the thickness of the filter component 12 extends into the opening 211.

[0109] In the dimming conversion component, since the image sensor component 13 is arranged far from the lens component 11, therefore, the concave portion 14 is at least arranged on the image sensor component 13, or the concave portion 14 is arranged on the image sensor component 13 and the filter component 12.

[0110] Specifically, referring to Figure 7a As shown, the image sensor component 13 includes a substrate 131 and an image sensor 132. Exemplarily, the substrate 131 can be a printed circuit board (Printed Circuit Board, abbreviated as PCB), and the image sensor 132 can be bonded to the PCB. The image sensor 132 corresponds to the light-emitting side of the lens component 11. In addition, the image sensor component 13 can also include a flexible printed circuit (Flexible Printed Circuit, abbreviated as FPC133). One end of the FPC133 is connected to the substrate 131, and the other end of the FPC133 extends outside the camera module 1 and is connected to the main board in the electronic device 100.

[0111] The filter component 12 includes a support frame 121 and a filter 122. The middle area of the support frame 121 has a mounting opening, and the filter 122 is bonded to the support frame 121 and covers the mounting opening. The area on the substrate 131 surrounding the image sensor 132 is a packaging area, and a packaging adhesive layer is arranged in the packaging area. The support frame 121 is adhesively connected to the packaging area of the substrate 131 through the packaging adhesive layer.

[0112] When the imaging module 1 works, the processor on the main board controls the imaging module 1 to take pictures. The external ambient light enters the imaging module 1 from the light incident side of the lens assembly 11. After the light exits from the lens assembly 11, it passes through the filter 122 and then irradiates onto the image sensor 132. The filter 122 filters the light, and then the image sensor 132 converts the optical signal into an electrical signal for imaging to improve the imaging effect.

[0113] Among them, the size of the filter 122 and the size of the image sensor 132 match the size of the light exit surface of the lens assembly 11. After the planar size of the lens assembly 11 increases, the size of the filter 122 and the size of the image sensor 132 can increase accordingly, or the size of the filter 122 and the size of the image sensor 132 remain unchanged. By forming a concave portion 14 on the substrate 131 of the image sensor assembly 13, or forming a concave portion 14 on the substrate 131 of the image sensor assembly 13 and the support frame 121 of the filter assembly 12, the local size of the edge of the dimming conversion component is reduced to form a clearance space between the edge of the dimming conversion component and the edge of the lens assembly 11.

[0114] Continue to refer to Figure 7a As shown, taking the imaging module 1 as a fixed-focus module (FF module) as an example, the lens assembly 11 may include a lens barrel (not shown in the figure) and a plurality of lenses (not shown in the figure) encapsulated in the lens barrel. The plurality of lenses may be arranged close to the light incident side of the lens barrel. The plurality of lenses may be stacked along the axial direction of the lens barrel, and the optical axis of the lens is parallel to the axial direction of the lens barrel. Exemplarily, the optical axis of the lens assembly 11 may pass through the centers of the plurality of lenses. The dimming conversion component may be bonded to the light exit side of the lens barrel. For example, the support frame 121 of the filter assembly 12 is bonded to the end face on the light exit side of the lens barrel.

[0115] Regarding the increase in the planar size of the lens assembly 11 of the fixed-focus module, it may be that the planar size of the lens arranged in the lens barrel increases. In this way, the light flux of the lens assembly 11 can be increased, and the shooting effect of the imaging module 1 can be improved. At this time, the size of the filter 122 and the size of the image sensor 132 can increase accordingly. By reducing the sizes of the support frame 121 and the substrate 131, the planar size of the dimming conversion component is made to match the planar size of the lens assembly 11.

[0116] Taking the imaging module 1 as an example of an autofocus module (AF module), the lens assembly 11 may include a lens 111 (not shown in the figure) and a driving device 112 (not shown in the figure). The driving device 112 is used to drive the lens 111 to move. For example, the driving device 112 drives the lens 111 to move along its own optical axis direction to achieve the focusing function of the imaging module 1. Alternatively, the driving device 112 drives the lens 111 to move along the plane direction where it is located, that is, the driving device 112 drives the lens 111 to move along the direction perpendicular to its optical axis to achieve the anti-shake function of the imaging module 1. Among them, the driving device 112 includes a housing 1121, and the lens 111 is movably arranged in the housing 1121. The dimming conversion component can be connected to the outer surface of the housing 1121 of the driving device 112. For example, the support frame 121 of the filter component 12 is adhesively bonded to the outer surface of the housing 1121 corresponding to the light-emitting side of the lens 111.

[0117] Regarding the increase in the planar size of the lens assembly 11 of the autofocus module, it can be that the planar size of the housing 1121 of the driving device 112 increases while the planar size of the lens 111 remains unchanged. At this time, the sizes of the filter 122 and the image sensor 132 can remain unchanged, and the sizes of the support frame 121 and the substrate 131 can be increased accordingly to make the planar size of the dimming conversion component match the size of the lens assembly 11. Or, the planar size of the housing 1121 of the driving device 112 does not increase, but the planar size of the lens 111 increases. For example, the planar size of the lens in the lens 111 increases. At this time, the sizes of the filter 122 and the image sensor 132 can increase accordingly, and the sizes of the support frame 121 and the substrate 131 remain unchanged or decrease to make the planar size of the dimming conversion component match the planar size of the lens assembly 11.

[0118] Referring to Figure 7a As shown, as an implementation manner, the concave portion 14 on the dimming conversion component can be formed only on the image sensor assembly 13. At this time, in the planar direction of the imaging module 1 (the plane perpendicular to the optical axis of the imaging module 1), the edge of the support frame 121 of the filter component 12 is flush with the edge of the lens assembly 11, and at least a part of the circumferential region of the edge of the substrate 131 of the image sensor assembly 13 has a concave portion 14, and a clearance space is formed between the edge of the concave portion 14 of the substrate 131 and the edge of the lens assembly 11.

[0119] Corresponding to the concave portion 14 on the substrate 131, the reinforcing portion 212 extending from the inner edge of the opening 211 on the support plate 21 extends into the relief space outside the circumferential side of the substrate 131, and the portion of the inner edge of the opening 211 corresponding to the support frame 121 is located outside the side wall surface of the lens assembly 11. Referring to FIG. 7, at this time, the reinforcing portion 212 is a stepped portion 212a extending inward from the inner edge of the opening 211, and in the thickness direction of the support plate 21, the stepped portion 212a is located in the portion of the support plate 21 away from the lens assembly 11. For example, the stepped portion 212a is flush with the surface of the support plate 21 on the side away from the lens assembly 11.

[0120] Referring Figure 7b and Figure 7c shown, as another embodiment, the concave portion 14 on the dimming conversion assembly is jointly formed by the image sensor assembly 13 and the filter assembly 12. Specifically, at least a partial area in the circumferential direction of the edge of the substrate 131 of the image sensor assembly 13 has a first concave portion 141, and at least a partial area in the circumferential direction of the edge of the support frame 121 of the filter assembly 12 has a second concave portion 142. The edges of the first concave portion 141 and the second concave portion 142 are both located inside the edge of the lens assembly 11, and the first concave portion 141 and the second concave portion 142 jointly constitute the concave portion 14 of the dimming conversion assembly.

[0121] A first relief space is formed between the edge of the first concave portion 141 and the edge of the lens assembly 11, and a second relief space is formed between the edge of the second concave portion 142 and the edge of the lens assembly 11. The first relief space and the second relief space jointly constitute the relief space. Correspondingly, the reinforcing portion 212 extending from the inner edge of the opening 211 on the support plate 21 includes a portion extending into the first relief space between the edge of the first concave portion 141 and the lens assembly 11, and also includes a portion extending into the second relief space between the edge of the second concave portion 142 and the lens assembly 11.

[0122] Among them, the second concave portion 142 at the edge of the support frame 121 corresponds to the first concave portion 141 at the edge of the substrate 131, and the reinforcing portion 212 at the inner edge of the opening 211 on the support plate 21 matches the first concave portion 141 and the second concave portion 142, so that the first concave portion 141 on the substrate 131 extends into the portion of the reinforcing portion 212 at the inner edge of the opening 211 corresponding to the second concave portion 142 at the edge of the support frame 121, and the substrate 131 passes through the opening area surrounded by the portion of the reinforcing portion 212 corresponding to the second concave portion 142 and extends into the opening area surrounded by the portion of the reinforcing portion 212 corresponding to the first concave portion 141.

[0123] Referring Figure 7bAs shown, in a specific embodiment, the orthographic projection of the image sensor component 13 on the filter component 12 can completely cover the filter component 12, that is, in the thickness direction of the dimming conversion component, the projection of the image sensor component 13 on the filter component 12 completely covers the filter component 12. For example, the circumferential edges of the support frame 121 of the filter component 12 are flush with the circumferential edges of the substrate 131 of the image sensor component 13, that is, the edges of the second concave portion 142 on the support frame 121 are flush with the edges of the first concave portion 141 on the substrate 131. Thus, the size of the first relief space formed between the edge of the second concave portion 142 of the support frame 121 and the edge of the lens component 11 can be the same as the size of the second relief space formed between the edge of the first concave portion 141 of the substrate 131 and the edge of the lens component 11.

[0124] Alternatively, the edge of the second concave portion 142 on the support frame 121 is retracted inside the edge of the first concave portion 141 on the substrate 131, and the cross-sectional area of the second relief space formed between the edge of the second concave portion 142 of the support frame 121 and the edge of the lens component 11 is larger than the cross-sectional area of the first relief space formed between the edge of the first concave portion 141 of the substrate 131 and the edge of the lens component 11.

[0125] For the case where the circumferential edges of the support frame 121 are flush with the circumferential edges of the substrate 131 and the cross-sectional area of the second relief space is the same as the cross-sectional area of the first relief space, in the thickness direction of the support plate 21, the inner edge of the opening 211 can extend inwardly as a whole to form a reinforcing portion 212, that is, the reinforcing portion 212 occupies the entire thickness of the support plate 21, the two side surfaces of the reinforcing portion 212 are respectively flush with the two side surfaces of the support plate 21, and the end surfaces of the reinforcing portion 212 (the surfaces of the side walls of the reinforcing portion 212 facing the dimming conversion component) are flush.

[0126] For the case where the edge of the second concave portion 142 of the support frame 121 is retracted inside the edge of the first concave portion 141 of the substrate 131 and the cross-sectional area of the second relief space is larger than the cross-sectional area of the first relief space, since the substrate 131 needs to pass through the opening area surrounded by the part of the reinforcing portion 212 extending into the second relief space, therefore, the length of the part of the reinforcing portion 212 extending into the second relief space cannot exceed the width of the first relief space. Based on this, the part of the reinforcing portion 212 extending into the second relief space can be the same as the part of the reinforcing portion 212 extending into the first relief space, that is, the end surfaces of the reinforcing portion 212 are flush.

[0127] Refer to Figure 7cAs shown, in another specific embodiment, the first concave portion 141 on the circumferential edge of the substrate 131 of the image sensor assembly 13 may be located inside the second concave portion 142 on the circumferential edge of the support frame 121 of the filter assembly 12. That is, the first concave portion 141 on the edge of the substrate 131 is retracted inside the second concave portion 142 on the edge of the support frame 121, and the second concave portion 142 on the edge of the support frame 121 is retracted inside the edge of the lens assembly 11. Thus, the cross-sectional area of the first relief space formed between the edge of the first concave portion 141 of the substrate 131 and the edge of the lens assembly 11 is larger than the cross-sectional area of the second relief space formed between the edge of the second concave portion 142 of the support frame 121 and the edge of the lens assembly 11.

[0128] Correspondingly, in the thickness direction of the support plate 21, the reinforcing portion 212 may include a first reinforcing portion 2121 and a second reinforcing portion 2122. The first reinforcing portion 2121 correspondingly extends into the first relief space, and the second reinforcing portion 2122 correspondingly extends into the second relief space. Corresponding to the positional relationship between the substrate 131 and the support frame 121, the first reinforcing portion 2121 is located on the part of the support plate 21 away from the lens assembly 11, and the second reinforcing portion 2122 is located on the part of the support plate 21 close to the lens assembly 11.

[0129] Since the edge of the first concave portion 141 is retracted inside the edge of the second concave portion 142 and the cross-sectional area of the first relief space is larger than that of the second relief space, in order to utilize the extra space in the first relief space, the extension length of the first reinforcing portion 2121 may be greater than that of the second reinforcing portion 2122, and the end of the first reinforcing portion 2121 extends out beyond the second reinforcing portion 2122. Thus, the extension length of the reinforcing portion 212 can be increased, the area of the opening 211 on the support plate 21 can be reduced, and the structural strength of the support plate 21 can be improved. Wherein, a stepped surface 2121a is formed between the first reinforcing portion 2121 and the second reinforcing portion 2122, and the stepped surface 2121a faces the filter assembly 12.

[0130] Figure 8 It is a cross-sectional view of the installation structure of the fourth camera module provided by the embodiment of the present application. Refer to Figure 8 As shown, the camera module 1 may further include a protective cover 15, and the protective cover 15 wraps the outside of the dimming conversion component and the lens assembly 11. Among them, the protective cover 15 wraps the whole dimming conversion component and the side wall of the lens assembly 11, and the light incident side of the lens assembly 11 is exposed outside the protective cover 15 to facilitate the entry of external ambient light into the lens assembly 11.

[0131] Taking the imaging module 1 as an example of an autofocus module, since the lens 111 can move within the housing 1121 of the driving device 112, there is a gap between the lens 111 and the housing 1121. Foreign objects such as dust and moisture in the outside world can easily enter the dimming conversion component through the gap between the lens 111 and the housing 1121, which will affect the filter 122 and the image sensor 132, and affect the imaging effect of the imaging module 1. By covering the outside of the dimming conversion component and the lens assembly 11 with a protective cover 15, the protective cover 15 can play a sealing role to prevent foreign objects in the external environment from entering the dimming conversion component and protect the performance of the dimming conversion component.

[0132] For a fixed-focus module, since the lens is encapsulated within the lens 111, the lens assembly 11 has good sealing performance. Moreover, the dimming conversion component is usually encapsulated on the lens assembly 11 with sealant. Therefore, the overall sealing performance of the fixed-focus module is good. Thus, a protective cover 15 can be covered outside the dimming conversion component and the lens assembly 11, or the protective cover 15 can also not be provided outside the dimming conversion component and the lens assembly 11.

[0133] Exemplarily, the protective cover 15 sleeved outside the dimming conversion component and the lens assembly 11 can be a protective cover 15 made of metal. The protective cover 15 made of metal has good strength and also has a signal shielding effect, which can shield the interference of external signals on the imaging module 1.

[0134] Corresponding to the concave portion 14 provided on the circumferential outer edge of the dimming conversion component, the protective cover 15 has a recessed portion 151. The recessed portion 151 on the protective cover 15 surrounds the outside of the concave portion 14 of the dimming conversion component. The size of the recessed portion 151 of the protective cover 15 contracts inward so that the size of the lower part of the protective cover 15 (the part of the protective cover 15 corresponding to the dimming conversion component) is smaller than the size of the upper part of the protective cover 15 (the part of the protective cover 15 corresponding to the lens assembly 11). The recessed portion 151 on the protective cover 15 provides space for the inner edge of the opening 211 of the support plate 21 to be provided with a reinforcing portion 212, and the protective cover 15 can extend into the opening area surrounded by the reinforcing portion 212 at the inner edge of the opening 211.

[0135] Figure 9 This is a cross-sectional view of the installation structure of the fifth imaging module provided by the embodiment of the present application. Refer to Figure 9 As shown, in some embodiments, the imaging module 1 may further include a bracket 16. The bracket 16 is sleeved on the side wall of the lens assembly 11, and the bracket 16 is fixedly connected to the middle frame 2. Exemplarily, one side of the bracket 16 facing the support plate 21 is fixedly connected to the support plate 21, or the surface of the bracket 16 opposite to the frame portion 22 is attached to the frame portion 22, and the bracket 16 is fixedly connected to the frame portion 22. The imaging module 1 is fixedly installed on the middle frame 2 through the bracket 16.

[0136] In a specific application, when there is no protective cover 15 wrapped around the imaging module 1, the imaging module 1 can be directly mounted and fixed on the middle frame 2 by relying on the outer sidewall of the lens assembly 11. For example, the lens barrel of the lens assembly 11 of the fixed-focus component is connected to the middle frame 2, and the housing 1121 of the driving device 112 of the autofocus module is connected to the middle frame 2. Alternatively, the imaging module 1 is connected to the middle frame 2 through a bracket 16 sleeved on the outer sidewall of the lens assembly 11.

[0137] When there is a protective cover 15 wrapped around the imaging module 1, the imaging module 1 can be mounted and fixed on the middle frame 2 by relying on the protective cover 15. For example, the protective cover 15 wrapped around the outer wall of the lens barrel of the fixed-focus component is bonded to the middle frame 2, or the protective cover 15 wrapped around the outer wall of the housing 1121 of the driving device 112 of the autofocus module is bonded to the middle frame 2. Alternatively, as shown in Figure 9 and

[0138] shown, a bracket 16 is further sleeved on the outside of the protective cover 15 outside the lens assembly 11. For example, the bracket 16 is bonded to the outer surface of the protective cover 15, and the bracket 16 is fixedly connected to the middle frame 2.

[0139] Figure 10a This is a cross-sectional view of the sixth installation structure of the imaging module provided by the embodiment of the present application; Figure 10b This is a cross-sectional view of the seventh installation structure of the imaging module provided by the embodiment of the present application. Referring to Figure 10a and Figure 10b shown, taking the autofocus module as an example, Figure 10a it shows the structure in which the protective cover 15 outside the light modulation conversion component and the housing 1121 of the driving device 112 is connected and fixed to the middle frame 2, Figure 10b it shows the structure in which a bracket 16 is further sleeved on the outside of the protective cover 15 wrapped around the sidewall of the housing 1121 of the driving device 112. Whether there is a bracket 16 sleeved on the outside of the protective cover 15 or not, since the protective cover 15 wraps the entire light modulation conversion component, the FPC 133 connected to the substrate 131 of the image sensor component 13 needs to extend from the opening side (the light incident side of the lens assembly 11) of the protective cover 15 to the outside of the imaging module 1.

[0140] Combined with Figure 5As shown, for the fixed-focus module without the protective cover 15, if a bracket 16 is sleeved on the outer sidewall of the lens assembly 11, the bottom end of the bracket 16 facing the support plate 21 of the middle frame 2 is attached to the support plate 21. If there is no avoidance gap provided between the bracket 16 and the support plate 21 for the FPC 133 to pass through, the FPC 133 needs to extend from the gap reserved between the outer sidewall of the lens barrel and the inner wall of the bracket 16 to the light incident side of the lens assembly 11, and extend out of the lens assembly 11 to the outside of the camera module 1 from the light incident side of the lens assembly 11.

[0141] Hereinafter, the camera module 1 is taken as an example of an autofocus module, and the FPC 133 passes through the opening side (the light incident side of the lens assembly 11) of the protective cover 15. It can be understood that when the camera module 1 is a fixed-focus module, there may also be a case where the FPC 133 passes through the light incident side of the lens barrel, which will not be elaborated here.

[0142] Refer to Figure 10a and Figure 10b As shown, one end of the FPC 133 is connected to the substrate 131 of the image sensor assembly 13, and the other end of the FPC 133 extends out of the camera module 1 from the light exit side of the lens assembly 11 and is connected to an external circuit (for example, connected to the main board). The middle section of the FPC 133 located between the substrate 131 and the light exit side of the lens assembly 11 is defined as its connection section 1331, and the connection section 1331 is located outside the sidewall of the housing 1121 of the driving device 112, and the connection section 1331 can extend along the sidewall of the housing 1121.

[0143] Since the connection section 1331 of the FPC 133 is located outside the sidewall of the housing 1121 of the driving device 112, in the plane direction of the camera module 1, the FPC 133 occupies at least part of the space on the outer periphery of the camera module 1, and the FPC 133 increases the planar size of the camera module 1. For the concave portion 14 on the dimming conversion component corresponding to the position where the connection section 1331 of the FPC 133 is located, the distance between the edge of the concave portion 14 and the connection section 1331 of the FPC 133 is larger than the distance between the edge of the concave portion 14 and the circumferential edge of the lens assembly 11.

[0144] Among them, the side of the connection section 1331 facing the support plate 21 is defined as its first side 1331a. Combining Figure 6As shown, the distance between at least a partial section of the first side 1331a of the FPC 133 connection section 1331 and the support plate 21 can be greater than or equal to the distance between the lens assembly 11 and the support plate 21. That is, in the axial direction of the camera module 1, the distance between at least a partial section of the connection section 1331 and the support plate 21 is greater than or equal to the distance between the lens assembly 11 and the support plate 21. In this way, the reinforcing portion 212 at the inner edge of the opening 211 of the support plate 21 can extend from the outside of the FPC 133 inwardly toward the edge of the concave portion 14 of the light modulation conversion component. The connection section 1331 of the FPC 133 can provide an extension interval for the reinforcing portion 212, increase the extension length of the reinforcing portion 212, reduce the area of the opening region surrounded by the reinforcing portion 212, increase the coverage area of the support plate 21, and improve the structural strength of the middle frame 2.

[0145] Figure 11 is a design schematic diagram of an FPC provided by an embodiment of the present application. Refer to Figure 11 As shown, the flexible circuit board can be connected to one side of the substrate 131 and extend along the side where it is connected to the substrate 131. Combining Figure 10a and Figure 10b As shown, taking the autofocus module as an example, after the FPC 133 extends from the side where it is connected to the substrate 131, in the axial direction of the lens assembly 11, the FPC 133 extends along the outer sidewall of the housing 1121 of the driving device 112 from this side and extends from the side of the housing 1121 facing away from the image sensor assembly 13.

[0146] Among them, the connection section 1331 of the FPC 133 is the part corresponding to the outer sidewall of the housing 1121, and the part of the connection section 1331 of the FPC 133 outside the housing 1121 of the driving device 112 corresponds to the corresponding side where the FPC 133 is connected to the substrate 131. Since the connection section 1331 of the FPC 133 is only located on one side of the housing 1121, the connection section 1331 of the FPC 133 on this side of the housing 1121 can provide extra space to increase the extension length of the reinforcing portion 212 at the corresponding part of the inner edge of the opening 211 of the support plate 21.

[0147] Figure 12 is another design schematic diagram of an FPC provided by an embodiment of the present application; Figure 13 is the third design schematic diagram of an FPC provided by an embodiment of the present application. Refer to Figure 12 and Figure 13 As shown, in addition to Figure 11 the structure of the FPC 133 shown in, after the FPC 133 extends from one end connected to the substrate 131 of the image sensor assembly 13, the FPC 133 can extend circumferentially around the outer sidewall of the lens assembly 11. After winding, the FPC 133 extends from the light incident side of the lens assembly 11.

[0148] Figure 14a A cross-sectional view of the eighth installation structure of the camera module provided by the embodiment of the present application; Figure 14b A cross-sectional view of the ninth installation structure of the camera module provided by the embodiment of the present application. Refer to Figure 14a and Figure 14b As shown, continuing with the autofocus module as an example, Figure 14a In the camera module 1, the protective cover 15 is fixedly connected to the middle frame 2, Figure 14b In the camera module 1, the camera module 1 is fixedly connected to the middle frame 2 by sleeving a bracket 16 outside the protective cover 15. Among them, the part of the FPC 133 wound around the outer side wall of the lens assembly 11 is the connection section 1331 of the FPC 133. The width direction of the connection section 1331 of the FPC 133 can be the thickness direction of the housing 1121 of the driving device 112, and the first side 1331a of the connection section 1331 of the FPC 133 faces the support plate 21.

[0149] Exemplarily, as shown in combination with Figure 12 As a specific implementation manner, the FPC 133 is connected to one side of the substrate 131. After the FPC 133 extends from the side where it is connected to the substrate 131, it extends to the opposite sides of the substrate 131. After the FPC 133 bypasses the opposite sides of the lens assembly 11 respectively, it extends to the other side opposite to the side where it is connected to the substrate 131, and extends from this side in a direction away from the image sensor assembly 13, and extends out of the camera module 1.

[0150] In combination with Figure 13 As shown, as another specific implementation manner, the FPC 133 is connected to the opposite sides of the substrate 131. After the FPC 133 extends from the opposite sides where it is connected to the substrate 131, the FPCs 133 on both sides extend towards each other along the outer side wall of the lens assembly 11. After winding around one side between the corresponding opposite sides of the substrate 131 of the lens assembly 11, it extends from this side in a direction away from the image sensor assembly 13, and extends out of the camera module 1.

[0151] In some other implementation manners, the FPC 133 can be wound around the outside of the lens assembly 11 by other winding methods. For example, the FPC 133 is connected to one side of the substrate 131, and the FPC 133 extends along the outer side wall of the lens assembly 11 in a clockwise or counterclockwise direction from the side where it is connected to the substrate 131 for half a turn or one turn, and then extends out of the camera module 1. This embodiment does not make specific limitations on this.

[0152] By enabling the FPC 133 to extend circumferentially around the lens module 11, the portion of the FPC 133 wound around the outside of the lens module 11 forms the movable portion of the FPC 133. This portion of the FPC 133 provides the condition for the translation of the image sensor module 13 and can bend or stretch in cooperation with the translation of the image sensor module 13. Therefore, it can be applied to the camera module 1 that compensates for the hand shake amount by translating the image sensor module 13, realizing the anti-shake function of the camera module 1. Among them, the portion of the FPC 133 wound around the outside of the outer side wall of the lens module 11 is the connection section 1331 of the FPC 133.

[0153] Combined with Figure 14a and Figure 14b As shown, since the connection section 1331 of the FPC 133 is wound around the outside of the lens module 11 along the circumferential direction of the lens module 11, taking the opposite sides of the lens module 11 as an example, the connection sections 1331 of the FPC 133 can be provided on the outside of the opposite sides of the lens module 11. In this way, the connection sections 1331 of the FPC 133 on the opposite sides of the lens module 11 can both provide extra space, so that a larger clearance space is formed between the edges of the concave portions 14 provided on the opposite sides of the dimming conversion module and the corresponding sides of the FPC 133. Furthermore, the extension length of the reinforcing portions 212 on the opposite sides of the inner edge of the opening 211 can be increased, the area of the opening region surrounded by the reinforcing portions 212 on both sides can be reduced, and the strength of the support plate 21 can be improved.

[0154] In addition, it can be understood that the connection sections 1331 of the FPC 133 are provided on three sides in the circumferential direction of the lens module 11 to increase the extension length of the reinforcing portions 212 on the three sides of the inner edge of the opening 211. Or, the connection sections 1331 of the FPC 133 are provided on each side in the circumferential direction of the lens module 11 to increase the extension length of the reinforcing portions 212 on each side of the inner edge of the opening 211. This embodiment does not make specific limitations on this.

[0155] Figure 15a It is a top view schematic diagram of a camera module provided by an embodiment of the present application; Figure 15b It is another top view schematic diagram of a camera module provided by an embodiment of the present application; Figure 15c It is a third top view schematic diagram of a camera module provided by an embodiment of the present application.

[0156] Taking Figure 7b as an example, where the edge of the substrate 131 of the image sensor module 13 in [[ ]] has a first concave portion 141, the edge of the support frame 121 of the filter module 12 has a second concave portion 142, and the edge of the second concave portion 142 is flush with the edge of the first concave portion 141, combined with Figure 6As shown, taking the planar shape of the dimming conversion component as a polygon as an example, the concave portion 14 can be located on the side or corner of the dimming conversion component. The concave portion 14 can be formed by the overall inward retraction of one or more sides of the dimming conversion component, or by the inward retraction of a partial area of one or more sides of the dimming conversion component, or by the inward retraction of one or more corners of the dimming conversion component.

[0157] Combined with Figure 5 As shown, the reinforcing portion 212 extending inward from the inner edge of the opening 211 on the support plate 21 corresponds to the concave portion 14 of the dimming conversion component. The reinforcing portion 212 extends into the clearance space formed between the edge of the concave portion 14 and the edge of the lens assembly 11. Therefore, the shape and size of the opening 211 with the reinforcing portion 212 match the shape and size of the dimming conversion component with the concave portion 14.

[0158] Taking the concave portion 14 extending along the side of the dimming conversion component as an example, at least one side of the dimming conversion component is provided with the concave portion 14, and a reinforcing portion 212 is formed on the side of the inner edge of the opening 211 on the support plate 21 corresponding to the concave portion 14 of the dimming conversion component. Taking one side of the dimming conversion component as an example, the concave portion 14 can extend to cover the entire area of the side. In this way, the reinforcing portion 212 on the inner edge of the opening 211 can correspondingly cover the entire side of the opening 211, which can increase the coverage area of the reinforcing portion 212, reduce the opening area of the opening 211, and improve the structural strength of the support plate 21.

[0159] Referring to Figure 15a As shown, as a specific implementation manner, the concave portions 14 can be provided on opposite sides of the dimming conversion component. The side walls on opposite sides of the dimming conversion component are retracted inward as a whole with respect to the lens assembly 11. Correspondingly, the two inner edges of the opening 211 corresponding to the two side walls of the concave portion 14 extend inward to form the reinforcing portions 212.

[0160] Referring to Figure 15b As shown, as another specific implementation manner, the concave portions 14 can be provided on each side in the circumferential direction of the dimming conversion component. The circumferential edge of the dimming conversion component is retracted inward as a whole with respect to the lens assembly 11, and the concave portion 14 forms an annular structure. An annular clearance space is formed between the edge of the concave portion 14 and the edge of the lens assembly 11. Correspondingly, the inner edge of the opening 211 extends inward as a whole, and the reinforcing portions 212 are formed in a circle around the circumference of the inner edge of the opening 211.

[0161] In other implementation manners, the concave portion 14 can also be provided corresponding to the corner of the dimming conversion component. Taking the planar shape of the dimming conversion component as a rectangle as an example, at least one of the four corners of the dimming conversion component is formed with the concave portion 14. Exemplarily, referring to Figure 15cAs shown, concave portions 14 may be formed at the four corners of the dimming conversion component. The concave portions 14 at the four corners may be formed, for example, by removing materials from partial regions of the respective corners of the substrate 131 and the support frame 121.

[0162] Corresponding to the concave portions 14 provided at the corners of the dimming conversion component, reinforcing portions 212 are formed at the corners of the inner edge of the opening 211 on the support plate 21. The reinforcing portions 212 extending from the corners of the opening 211 reduce the area of the opening 211, increase the coverage area of the support plate 21, and enhance the structural strength of the support plate 21.
