Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic devices, and in particular to an electronic device. BACKGROUND

[0002] Due to the requirement of portability of electronic devices by consumers, how to make the electronic devices thin and light has become the focus of various electronic device manufacturers. In order to realize the thin and light design of the electronic device, an important improvement direction is to reduce the volume of the electronic device, but reducing the volume of the electronic device inevitably increases the pressure of the internal space of the electronic device.

[0003] In the process of reducing the volume of the electronic device, the modification of some structures inside the electronic device is involved, so that the space occupied by the structure is reduced to help reduce the volume of the electronic device. However, the modification of some structures may cause the original electrical connection design to no longer be applicable to the modified structure, resulting in poor electrical connection of the electronic device. SUMMARY

[0004] The electronic device provided by the embodiments of the present application can reduce the problems caused by the thin and light design of the electronic device, and improve the reliability of the thin and light electronic device.

[0005] To achieve the above object, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, an electronic device is provided. The electronic device can include a circuit board, a main body component, and a mounting bracket. The circuit board includes a board body and a main board bracket fixed to the board body. The main body component is fixed to the board body; in a direction parallel to the board body, the main body component includes a first conductive portion and a first force receiving portion arranged oppositely. The mounting bracket is located on a side of the board body close to the main board bracket and is located at the periphery of the main body component. In a direction perpendicular to the board body, the main board bracket and the mounting bracket interfere with each other. In the direction parallel to the board body, the mounting bracket includes a second conductive portion and a second force receiving portion arranged oppositely, the second force receiving portion and the first force receiving portion form a first interaction force, and the first conductive portion and the second conductive portion form a second interaction force, so that the first conductive portion and the second conductive portion form a conductive path.

[0007] Hereinafter, the main body component is a camera, and the mounting bracket is a camera bracket, but it is not limited to the main body component and the mounting bracket.

[0008] In the direction perpendicular to the board body, the main board bracket and the mounting bracket interfere with each other, which means that in the height direction perpendicular to the board body, the height range of the main board bracket and the height range of the mounting bracket overlap. It can be understood that the main board bracket and the mounting bracket exist in a plane parallel to the board body.

[0009] Exemplarily, the mainboard support can include a spring piece. The spring piece can be welded at a welding point of the support body. The spring piece is used to be electrically connected with a decorative metal in the electronic device to conduct the decorative metal to a grounding point. The spring piece can extend downward, and a notch of the camera support can be arranged below the spring piece, so that the mounting support avoids the spring piece through the notch. In this way, the spring piece above is not affected in function by avoiding the notch, and in the case that the camera support and the spring piece interfere with each other in the height direction of the electronic device, the height of the mainboard support can be increased to avoid the spring piece, which is beneficial to reduce the thickness of the electronic device.

[0010] The first stress part and the second stress part form a first interaction force, which means that the second stress part and the first stress part can be in stable contact. Similarly, the first conductive part and the second conductive part form a second interaction force, which means that the second conductive part and the first conductive part can be in stable contact.

[0011] In the present application, by modifying the mounting support and the mainboard support on the circuit board, the mounting support and the mainboard support are assembled to interfere with each other in the direction perpendicular to the circuit board, so as to reduce the space volume occupied by the mounting support and the mainboard support. On this basis, the conductor on the outer surface of the main part can be in stable contact with the conductor of the mounting support, so as to reduce or even eliminate the interference of the third harmonic generated between the two conductors on the internal electronic devices of the electronic device.

[0012] In some possible implementations of the first aspect, the mounting support is provided with a notch, and the mainboard support includes an extension part, at least part of the extension part being located in the notch.

[0013] In some examples, the number of extension parts can be equal to the number of notches provided on the camera support. Each extension part is correspondingly accommodated in a notch. In other examples, the number of extension parts can be greater than the number of notches provided on the camera support. A plurality of extension parts can be located in one notch.

[0014] The mainboard support is accommodated in the notch through the extension part, so that the position of the camera support in the length direction and the width direction of the electronic device cannot be moved. In addition, the extension part abuts against the bottom wall of the notch, on the one hand, the camera support can support the mainboard support through the extension part, and on the other hand, the mainboard support can provide downward pressure to the camera support through the extension part to limit the position of the camera support in the height direction of the electronic device. In this way, the mainboard support can reliably fix the camera support on the board body.

[0015] The extension is accommodated in the notch, so that the camera support and the mainboard support interfere in the height direction of the electronic device. Compared with the extension abutting against the top of the camera support when the camera support has no notch, the space volume occupied by the camera support and the mainboard support in the height direction of the electronic device can be reduced.

[0016] In some possible implementation manners of the first aspect, the cross section of the mounting support is a rectangular frame, and the at least partial notch is located at a corner of the rectangular frame. The cross section is parallel to the plate body.

[0017] The camera support can include first, second, third and fourth frame edges connected in sequence. The notch can be located at a corner of any two frame edges connected in sequence.

[0018] Exemplarily, the camera support is provided with one notch, and the notch can be located at the connecting corner of the first frame edge and the second frame edge. It can be understood that the notch includes a recess whose extension direction is parallel to the length direction of the electronic device, and a recess whose extension direction is parallel to the width direction of the electronic device. In a top-down perspective view, the notch can be "L"-shaped.

[0019] In this way, the mainboard support is accommodated in the notch through the extension, and one or more (two or more) notches can help to limit the position of the camera support in the length direction and the width direction of the electronic device.

[0020] In some possible implementation manners of the first aspect, the first conductive part includes a first main body part and a first protruding rib protruding from the first main body part towards the second conductive part, and a second interaction force is formed between the second conductive part and the first protruding rib.

[0021] The length direction in which the first protruding rib extends can be parallel to the height direction of the electronic device, the height direction in which the first protruding rib extends can be parallel to the width direction of the electronic device, and the extension height of the first protruding rib can be greater than the distance between the first main body part and the frame edge.

[0022] It can be understood that an interference fit is formed between the first protruding rib and the frame edge of the camera support, and the second interaction force is formed. The second interaction force includes the frame edge. The pressure (force) on the first protruding rib, and the pressure (counterforce) provided by the first protruding rib to maintain its shape and position on the frame edge. The greater the interference amount between the first protruding rib and the frame edge, the greater the second interaction force between the first protruding rib and the second frame edge.

[0023] Since the length of the first protruding rib in the direction parallel to the height of the electronic device is relatively long, even if the notch is located at the frame edge, the top edge of the frame edge sinks, and the top edge of the corresponding first protruding rib in contact with the frame edge can sink synchronously with the top edge of the frame edge. The extension length of the first protruding rib after the top edge sinks can still ensure that the interference fit between the frame edge and the first protruding rib is formed, and the second interaction force is formed.

[0024] In the embodiment, since the interference fit is formed between the first protruding rib and the frame edge, the camera and the frame edge can also include an alloy with low surface treatment requirements. The low surface treatment requirement can mean that the alloy surface forms an oxide film, a film, or other surface film layers. For example, the camera and the frame edge can include suitable alloys such as magnesium alloys, aluminum alloys, stainless steels, and the like. Because the interference fit is formed between the first protruding rib and the frame edge, the friction between the first protruding rib and the frame edge is relatively large during the assembly of the camera to the camera support, and the oxide film or other surface film layers formed on the surface of the alloy can be damaged, so that the surface film layers do not affect the stable contact between the first protruding rib and the frame edge to form the conductive path.

[0025] In the embodiment, the second interaction force between the frame edge and the first protruding rib ensures the stable contact between the frame edge and the first protruding rib, and can avoid the phenomenon that the frame edge and the first protruding rib are not in contact, thereby reducing or even eliminating the interference of the third harmonic generated between the camera and the frame edge on the internal electronic devices of the smart phone.

[0026] In some possible implementation modes of the first aspect, the second conductive part includes a second main part and a second protruding rib protruding from the second main part and close to the first conductive part. The second interaction force is formed between the first conductive part and the second protruding rib.

[0027] The effect of the second interaction force formed between the second protruding rib and the camera can refer to the effect of the second interaction force formed between the first protruding rib and the frame edge, which will not be described here.

[0028] In some possible implementation modes of the first aspect, the electronic device further includes an elastic member. The elastic member is located between the first force receiving part and the second force receiving part. The first interaction force includes the pressure of the second force receiving part on the elastic member and the pressure of the elastic member on the first force receiving part.

[0029] The elastic member can be made of a composite material with elastic deformation capability such as rubber, plastic, silicone, spring steel, and the like, which is not limited in the application.

[0030] The first force receiving part abuts against the second force receiving part via the elastic member, forming a first interaction force. The first interaction force includes a pressure (action force) provided by the first force receiving part to the elastic member, a pressure (reaction force) provided by the elastic member to the first force receiving part for maintaining the shape and position of the elastic member, a pressure (action force) provided by the second force receiving part to the elastic member, and a pressure (reaction force) provided by the elastic member to the second force receiving part for maintaining the shape and position of the elastic member.

[0031] The pressure provided by the elastic member to the first force receiving part is actually the pressure provided by the elastic member to the camera. After the camera is subjected to the pressure, a dynamic force is generated to move the second conductive part closer to the second conductive part, thereby pressing the second conductive part. The camera pressing the second conductive part forms a second interaction force between the first conductive part and the second conductive part of the camera. The size of the second interaction force depends on the pressure provided by the elastic member to the second force receiving part. The greater the pressure provided by the elastic member to the second force receiving part, the greater the second interaction force.

[0032] In this way, the second interaction force between the first conductive part and the second conductive part ensures stable contact between the first conductive part and the second conductive part, avoids the phenomenon of similar connection and non-connection between the first conductive part and the second conductive part, and reduces or even eliminates the interference of the third harmonic generated between the first conductive part and the second conductive part on the internal electronic devices of the smart phone.

[0033] In some possible implementation manners of the first aspect, the first force receiving part is provided with a first recess, and part of the elastic member is located in the first recess. In some possible implementation manners of the first aspect, the second force receiving part is provided with a second recess, and part of the elastic member is located in the second recess.

[0034] By accommodating part of the elastic member in the first recess and the second recess, the problem of insufficient space between the first force receiving part and the second force receiving part caused by the internal space of the electronic device can be overcome. The elastic member can provide pressure to the camera, thereby forming a second interaction force between the first conductive part and the second conductive part, ensuring stable contact between the first conductive part and the second conductive part, avoiding the phenomenon of similar connection and non-connection between the first conductive part and the second conductive part, and reducing or even eliminating the interference of the third harmonic generated between the first conductive part and the second conductive part on the internal electronic devices of the smart phone.

[0035] In some possible implementation manners of the first aspect, the elastic member includes an elastic main body part and N elastic protruding parts protruding outward from the elastic main body part; each elastic protruding part provides pressure to the first force receiving part. N is a positive integer.

[0036] The elastic member contacts the camera through a plurality of elastic protrusions, so that the camera is subjected to relatively even force, and eccentricity, centrifugation and rotation of the camera are prevented, the reliability of assembly of the camera and the camera support is ensured, and the yield of the electronic device is improved.

[0037] In some possible implementation manners of the first aspect, the second conductive part includes N second protrusions. In a direction perpendicular to the extension direction of the elastic main body part, one second protrusion is located on the same straight line as one elastic protrusion, and different second protrusions correspond to different elastic protrusions.

[0038] The elastic member includes an elastic main body part and two elastic protrusions. The frame edge can include a main body part and two second protrusions. One second protrusion can be located on a straight line in the extension height direction of one elastic protrusion, and the other second protrusion can be located on a straight line in the extension height direction of the other elastic protrusion.

[0039] In this way, the pressure provided by one elastic protrusion to the first force-receiving part can be located on the same straight line as the second interaction force between the first conductive part and one second protrusion. The pressure provided by the other elastic protrusion to the first force-receiving part can be located on the same straight line as the second interaction force between the first conductive part and the other second protrusion.

[0040] In this way, the pressure provided by the elastic protrusion to the camera is more efficient in increasing the second interaction force between the first conductive part and the second protrusion, thereby improving the stability of contact between the first conductive part and the second protrusion.

[0041] In some possible implementation manners of the first aspect, the elastic protrusion is in a slope shape near the end of the plate body. The slope bottom has the smallest size in the electronic device width direction, and the slope top has the largest size in the electronic device width direction.

[0042] In this way, during assembly of the camera and the camera support, the camera can be assembled into the camera support along the slope. During initial assembly of the camera into the camera support, the pressure between the camera and the elastic protrusion is small, so that the camera is facilitated to enter the camera support, and the assembly efficiency of the electronic device is improved.

[0043] In some possible implementation manners of the first aspect, the electronic device further includes an elastic conductive body. The elastic conductive body is located between the first conductive part and the second conductive part. The first conductive part, the elastic conductive body and the second conductive part collectively form a conductive path; the second interaction force includes pressure of the second conductive part on the elastic conductive body, and pressure of the elastic conductive body on the first conductive part.

[0044] The elastic conductor can include an elastic material and a conductive layer covering the entire outer surface of the elastic material. The conductive layer can be obtained by metallizing the surface of the elastic material. The elastic material can include rubber, plastic, silicone, spring steel, and other composite materials with elastic deformation capability. The conductive layer can include a nickel plating layer, a gold plating layer, a tungsten plating layer, and other metal plating layers, which have excellent electrical conductivity. Embodiments of the present application do not limit the specific materials of the elastic material and the conductive layer.

[0045] When the elastic conductor is in interference fit with the first conductive part and the second conductive part, the elastic conductor provides pressure to the camera, the camera forms a dynamic force close to the second force-receiving part, thereby forming a first interaction force between the first force-receiving part of the camera and the second force-receiving part of the camera support. The first interaction force includes the pressure (action force) of the first force-receiving part on the second force-receiving part, and the pressure (reaction force) provided by the second force-receiving part to the first force-receiving part to maintain its shape and position.

[0046] The first conductive part can form a second interaction force with the second conductive part through the elastic conductor. The second interaction force includes the pressure (action force) of the first conductive part on the elastic conductor, the pressure (reaction force) provided by the elastic conductor to the first conductive part to maintain its shape and position, the pressure (action force) of the elastic conductor on the second conductive part, and the pressure (reaction force) provided by the second conductive part to the elastic conductor to maintain its shape and position.

[0047] Since the length of the elastic conductor in the direction parallel to the Z-axis is relatively long, even if the notch is located at the second conductive part, the top edge of the second conductive part will sink, causing the top edge of the elastic conductor to sink synchronously with the top edge of the second conductive part. The extension length of the elastic conductor after the top edge sinks can still ensure that interference fit is formed between the first conductive part and the second conductive part, and the second interaction force is formed.

[0048] In this way, the first conductive part and the elastic conductor can be in stable contact, and the first conductive part and the conductive layer on the elastic conductor form a conductive path. The second conductive part and the elastic conductor can also be in stable contact, and the second conductive part and the conductive layer on the elastic conductor form a conductive path. Furthermore, the first conductive part, the elastic conductor, and the second conductive part collectively form a conductive path.

[0049] In some possible implementations of the first aspect, the main body component includes a camera, and the mounting support includes a camera support. In this way,

[0050] In some possible implementations of the first aspect, the main body component includes a speaker unit, and the mounting support includes a speaker support. BRIEF DESCRIPTION OF DRAWINGS

[0075] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application are within the scope of protection of this application.

[0076] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this application, unless otherwise stated, "a plurality of" means two or more.

[0077] In addition, in the present application, the orientation terms such as "upper", "lower", "left", "right" and the like can include, but are not limited to, the orientation defined by the relative placement of the components in the drawings. It should be understood that these directional terms are relative concepts, and they are used for relative description and clarification, which can change accordingly according to the change of the placement of the components in the drawings.

[0078] In describing some embodiments, the use of "connected", "coupled", and "in communication with" can be used. For example, the term "connected" can be used to mean that two or more components are in direct or indirect physical contact with each other. For example, A and B can be connected, which means that A and B are connected, or A and B are connected through other components. In addition, the term "coupled" can be an electrical connection that enables signal transmission. Coupling can mean direct coupling or indirect coupling.

[0079] "A, B, and C at least one of" has the same meaning as "at least one of A, B, or C", and includes the following combinations of A, B, and C: only A, only B, only C, a combination of A and B, a combination of A and C, a combination of B and C, and a combination of A, B, and C.

[0080] "A and / or B" includes the following three combinations: only A, only B, and a combination of A and B.

[0081] As used herein, "about", "approximately", or "approximately" includes the stated value and the average value within an acceptable deviation range of the specific value, wherein the acceptable deviation range is determined by the person of ordinary skill in the art considering the measurement being discussed and the error related to the measurement of the specific quantity (i.e., the limitations of the measurement system).

[0082] For the convenience of understanding, the technical terms involved in the present application are explained and described below.

[0083] 1. Electrostatic discharge (ESD)

[0084] ESD is a technology for studying the generation, hazards and protection of static electricity. In the electronics, semiconductor and optoelectronics industries, ESD can cause problems such as damage to electronic components, reduced performance, and even failure, reducing product reliability.

[0085] Therefore, anti-static structures are usually provided in products to suppress and eliminate static electricity accumulation, significantly reducing the product failure rate caused by static electricity and improving product quality.

[0086] 2. Electromagnetic compatibility (EMC)

[0087] EMC includes two parts of electromagnetic interference (EMI) and electromagnetic interference susceptibility (EMS).

[0088] The main content of EMI test can include: radiated emission (RE) test, conducted emission (CE) test, harmonic current test and flicker test, etc.

[0089] The main content of EMS test can include: radiated susceptibility (RS) test, conducted susceptibility (CS) test, ESD susceptibility test, electrical fast transient (EFT) test, surge test and power frequency magnetic susceptibility (PMS), etc.

[0090] 3. Radiated spurious emission (RSE)

[0091] RSE test is part of electromagnetic compatibility (EMC) test, which is used to evaluate the negative electromagnetic radiation generated by wireless communication equipment or transmitting equipment outside its working frequency range.

[0092] Figure 1 A partial perspective view of two metal conductors is shown; Figure 2 A front view of the contact of two metal conductors is shown.

[0093] At present, some functional modules (such as display screen, camera, speaker, etc.) inside electronic equipment need to discharge static electricity to the outside. The commonly used way is: Figure 1 and Figure 2As shown, the metal conductor 01 on the outer surface of the functional module is in contact with the external metal conductor 02 connected to the grounding point, so that the static electricity at the functional module is transmitted to the grounding point through the metal conductor 01 on the outer surface and the external metal conductor 02. Exemplarily, the metal conductor 01 on the outer surface of the functional module is in contact with the first end of the external metal conductor 02, and the second end of the external metal conductor 02 can be connected to the grounding point on the metal middle frame or the grounding point on the mainboard. In this way, the static electricity at the functional module can be transmitted to the grounding point through the metal conductor 01 on the outer surface and the external metal conductor 02, realizing the static electricity discharge of the functional module.

[0094] However, the contact between the metal conductor 01 on the outer surface of the functional module and the external metal conductor 02 (which can be understood as the surface of the metal of the functional module and the surface of the external metal conductor) is unstable and may not be connected. In this way, the two metal surfaces can easily cause tunneling effect and generate a large amount of third harmonic, causing interference with the internal electronic devices of the electronic equipment.

[0095] The nonlinear equation of the third harmonic current is:

[0096] Formula (1).

[0097] wherein, is a comprehensive constant; is the contact resistance between the two metal surfaces; is the contact pressure between the two metal surfaces; is the pressure coefficient, The value of depends on the shape of the two metal surfaces, for example, in the case of any metal surface with a convex hull =1 / 2, and for example, in the case of any metal surface with a spherical surface =1 / 3; is the fundamental current.

[0098] As can be seen from formula (1), the greater the contact pressure between the two metal surfaces, the smaller the third harmonic current; the smaller the contact resistance between the two metal surfaces, the smaller the third harmonic current.

[0099] Currently, in order to avoid the phenomenon of pseudo-contact between two metal surfaces, stable contact between the two metal surfaces is achieved. For example, in the case of two metal conductors that can be separated, a conductive foam, a metal spring, or other conductive components can be used to simultaneously contact the two metal conductors, and the conductive components are in a compressed state, so that the conductive components and the two metal conductors are in contact. In this way, stable contact between each metal conductor and the conductive component can ensure that the third harmonic generated by the two metal surfaces is within the permissible range of the RSE test, and the degree of interference with the electronic devices inside the electronic device is low. In addition, by using the conductive component to contact the metal conductor, stable contact between the conductive component and the metal conductor can still be ensured when the two metal conductors are subjected to impact or dynamic tolerance during installation.

[0100] For another example, in the case of two metal conductors that cannot be separated, screw fastening, adhesive bonding, or welding can be used to achieve stable contact between the two metal conductors, which can ensure that the third harmonic generated between the two metal conductors is within the permissible range of the RSE test, and the degree of interference with the electronic devices inside the electronic device is low.

[0101] However, as electronic devices become thinner and lighter, there is very little space available inside the electronic device, and some structures may be modified to reduce their space occupation inside the electronic device. After the structure is modified, the two stable contact methods described above may no longer be suitable for the modified structure, resulting in that the structure in some functional modules cannot ensure stable contact between the metal conductor on the outer surface of the functional module and the external metal conductor after modification.

[0102] Therefore, embodiments of the present application provide an electronic device. The electronic device includes a main body component, a mounting bracket, and a circuit board. In embodiments of the present application, by modifying the main board bracket on the mounting bracket and the circuit board, after the mounting bracket and the main board bracket are assembled, interference exists between the mounting bracket and the main board bracket in the direction perpendicular to the circuit board, thereby reducing the space volume occupied by the mounting bracket and the main board bracket. On this basis, the conductor on the outer surface of the main body component can stably contact the conductor of the mounting bracket, thereby reducing or even eliminating the interference of the third harmonic generated between the two conductors with the electronic devices inside the electronic device.

[0103] Embodiments of the present application provide an electronic device, which can include but is not limited to a smartphone, a tablet computer, a notebook computer, a handheld computer, a netbook, a personal digital assistant (PDA), a wearable electronic device (a smart watch, a smart bracelet, a smart ring, etc.), a virtual reality device, and the like. Embodiments of the present application do not limit the electronic device to a smartphone.

[0104] Referring to Figure 3 , Figure 3 A perspective structural schematic diagram of a smartphone is shown. The smartphone 100 can have a structure of a rectangular plate.

[0105] For convenience of the following description, an XYZ coordinate system is established, and the width direction of the smartphone 100 is defined as the X-axis direction, the length direction of the smartphone 100 is defined as the Y-axis direction, and the thickness direction of the smartphone 100 is defined as the Z-axis direction. In the following, the plane parallel to the X-axis direction and the Y-axis direction is referred to as the X-Y plane.

[0106] It can be understood that Figure 3 Only some components included in the smartphone 100 are shown schematically, and the actual shape, actual size, actual position, and actual structure of these components are not limited by Figure 3 .

[0107] Referring to Figure 4 , Figure 4 A perspective exploded schematic diagram of the smartphone shown in Figure 3 The smartphone 100 can include a screen 10, a back cover 20, a middle frame 30, a circuit board 40, a camera module 50, and a speaker module 60. In embodiments of the present application, the direction from the screen 10 to the back cover 20 is defined as from top to bottom.

[0108] The screen 10 can be used to display images, videos, and the like. The screen 10 can include a light-transmitting cover plate 11 and a display screen 12. In the Z-axis direction, the light-transmitting cover plate 11 and the display screen 12 are stacked. The light-transmitting cover plate 11 is mainly used to protect and prevent dust from the display screen 12. The material of the light-transmitting cover plate 11 includes but is not limited to glass. The display screen 12 can be a flexible display screen or a rigid display screen.

[0109] For example, the display screen 12 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MOLED) display screen, a quantum dot light-emitting diode (QLED) display screen, a liquid crystal display (LCD) display screen, etc., without limitation.

[0110] The back cover 20 can be used to protect the internal electronic components of the smartphone 100. The back cover 20 can be located on the side of the display screen 12 away from the light-transmitting cover 11. The back cover 20 can have a light-transmitting opening 21 that passes through the back cover 20. The shape of the light-transmitting opening 21 can be circular, rectangular, etc., and is not limited here.

[0111] The middle frame 30 may include a connected frame 31 and a middle plate 32. The frame 31 may be located between the rear cover 20 and the light-transmitting cover 11, and the frame 31 may be connected to the rear cover 20. For example, adhesive can be used to bond the frame 31 to the rear cover 20. Adhesive can also be used to bond the light-transmitting cover 11 to the frame 31. The middle plate 32 is connected to the inner surface of the frame 31 to achieve the installation and fixation of the middle plate 32. For example, the edge of the middle plate 32 can be fixed to the frame 31 by adhesive; or, for example, the middle plate 32 and the frame 31 can be integrally formed, that is, the middle plate 32 and the frame 31 are a single structural component.

[0112] like Figure 4 As shown, the middle board 32 may include a main board 321 and a sub-board 322. The main board 321 and the sub-board 322 can be two independent boards. The main board 321 and the sub-board 322 can be arranged at intervals along the Y-axis.

[0113] Circuit board 40 may be located on middle board 32. Circuit board 40 can be used to set up electronic devices and realize electrical connections between various electronic devices. In some examples, circuit board 40 may include main circuit board 41 and sub-circuit board 42. Main circuit board 41 may be fixed on main board 321, and sub-circuit board 42 may be fixed on sub-board 322.

[0114] The main circuit board 41 can be provided with a control chip. The control chip can be, for example, a system on chip (SOC), an application processor (AP), a double data rate (DDR) synchronous dynamic random access memory, a universal flash storage (UFS), and the like. In some embodiments, the main circuit board 41 is electrically connected to the display screen 12, and the main circuit board 41 is configured to control the display screen 12 to display images or videos.

[0115] The auxiliary circuit board 42 is configured to be provided with electronic devices such as a 5G antenna radio frequency front end, a universal serial bus (USB) device, a vibration motor, and the like.

[0116] The circuit board 40 can further include a connection structure 43. The connection structure 43 can be electrically connected to the main circuit board 41 and the auxiliary circuit board 42 to achieve data and signal transmission between the auxiliary circuit board 42 and the main circuit board 41. The connection structure 43 can include, but is not limited to, a flexible printed circuit (FPC), a wire, an enameled wire, or a structure formed by weaving a wire and a flexible material.

[0117] The camera module 50 can be located on the main circuit board 41. The number of camera modules 50 can be multiple, and the multiple camera modules 50 can be arranged in sequence on the main circuit board 41. Each camera module 50 can include a camera and a camera bracket. The camera bracket is fixed to the main circuit board 41, and the camera is assembled inside the camera bracket, so that the camera bracket can limit the movement of the camera in the X-axis direction and the Y-axis direction.

[0118] In some examples, the camera bracket can be a metal bracket. The camera bracket can be electrically connected to the grounding point of the main circuit board 41, so that static electricity at the camera bracket can be conducted to the grounding point of the main circuit board 41, thereby achieving static electricity discharge at the camera bracket.

[0119] The speaker module 60 can be located on the auxiliary circuit board 42. Each speaker module 60 can include a speaker unit and a speaker bracket. The speaker bracket is fixed to the auxiliary circuit board 42, and the speaker unit is assembled inside the speaker bracket, so that the speaker bracket can limit the movement of the speaker unit in the X-axis direction and the Y-axis direction.

[0120] In some examples, the speaker bracket can be a metal bracket. The speaker bracket can be electrically connected to the grounding point of the auxiliary circuit board, so that static electricity at the speaker bracket can be conducted to the grounding point of the auxiliary circuit board 42, thereby achieving static electricity discharge at the speaker bracket.

[0121] The following will be described in detail the design of the connection scheme between the camera module 50 and the main circuit board 41 for the thin design of the electronic device. It should be noted that the following is only an example of the connection between the camera module 50 and the main circuit board 41, and the connection between the actual loudspeaker module 60 and the secondary circuit board 42 can also be similarly designed for the thin design of the electronic device. In addition, other suitable functional modules can also be designed similarly.

[0122] Figure 5 The three-dimensional structure of the camera module is shown in Figure 4 The three-dimensional structure of the camera module is shown in Figure 6 The three-dimensional structure of the camera module is shown in Figure 5 The three-dimensional structure of the camera module is shown in Figure 7 A structure of the camera support is shown. Figure 5 The position relationship between the camera 51 and the camera support 52 can be seen. In combination with Figure 5 and Figure 6 As shown, the outer contour shape of the camera 51 in the X-Y plane can be approximately rectangular. The bottom of the camera 51 can be provided with a connector for BTB connection on the main circuit board 41, thereby providing an image signal to the control chip on the main circuit board 41.

[0123] In the X-Y plane, the camera support 52 can be located at the periphery of the camera 51. Exemplarily, the shape of the cross section perpendicular to the Z-axis direction (X-Y plane) can be a rectangular frame. It can be understood that the camera 51 is located inside the camera support 52 in the rectangular frame in the X-Y plane. Among them, the assembly method of the camera 51 and the camera support 52 is to push the camera 51 from the bottom of the camera support 52 upwards into the camera support 52, thereby completing the assembly of the camera 51 and the camera support 52. The disassembly method of the camera 51 and the camera support 52 is to press the camera 51 from top to bottom, so that the camera 51 leaves the camera support 52 from top to bottom, thereby completing the disassembly of the camera 51 and the camera support 52.

[0124] The camera support 52 can include a first frame edge 521, a second frame edge 522, a third frame edge 523 and a fourth frame edge 524. Among them, the extension direction of the first frame edge 521 and the third frame edge 523 can be parallel to the X-axis direction; the extension direction of the second frame edge 522 and the fourth frame edge 524 can be parallel to the Y-axis direction. The first frame edge 521, the second frame edge 522, the third frame edge 523 and the fourth frame edge 524 are connected end to end to form the camera support 52.

[0125] The camera 51 can include a first wall 511, a second wall 512, a third wall 513 and a fourth wall 514. The first wall 511 and the third wall 513 can extend parallel to the X-axis direction, and the second wall 512 and the fourth wall 514 can extend parallel to the Y-axis direction. The first wall 511, the second wall 512, the third wall 513 and the fourth wall 514 are connected end to end.

[0126] The camera holder 52 can further include at least one notch. The notch can be located at the top of at least one frame edge, and the opening faces upward.

[0127] In some examples, the camera holder 52 includes two notches. One notch can be provided on the first frame edge 521, and the other notch can be provided on the second frame edge 522. It can be understood that the extension direction of one notch is parallel to the X-axis direction, and the extension direction of the other notch is parallel to the Y-axis direction.

[0128] In other examples, as shown in Figure 5 and Figure 6 , the camera holder 52 includes one notch. The notch Q can be provided at the connecting corner of the first frame edge 521 and the second frame edge 522. It can be understood that the notch Q includes a recess extending parallel to the X-axis direction and a recess extending parallel to the Y-axis direction. From the top-down perspective, the notch Q can be "L" shaped.

[0129] In yet other examples, as shown in Figure 7 , the camera holder 52 includes two notches. One notch Q1 can be provided at the connecting corner of the first frame edge 521 and the fourth frame edge 524, and the other notch Q2 can be provided at the connecting corner of the second frame edge 522 and the third frame edge 523. It can be understood that both notches Q1 and Q2 include a recess extending parallel to the X-axis direction and a recess extending parallel to the Y-axis direction. From the top-down perspective, both notches Q1 and Q2 can be "L" shaped.

[0130] It should be noted that in the "L" shaped notch, the size of the recess parallel to the Y-axis direction in the Y-axis direction can be equal to or different from the size of the recess parallel to the X-axis direction in the X-axis direction.

[0131] Please refer to Figure 8 , Figure 8 for a perspective exploded view of the main circuit board, the camera holder and the camera in Figure 4 .

[0132] The main circuit board 41 can include a board body 411 and a main board support 412. The board body 411 can be provided with a plurality of control chips near a side surface of the screen 10. The main board support 412 can also be fixed to the board body 411 near the side surface of the screen 10.

[0133] The main board support 412 can include a support body 4121 and a plurality of connecting portions 4122. The connecting portions 4122 can extend along the Z-axis direction, the bottom ends of the connecting portions 4122 can be fixed to the board body 411, and the top ends of the connecting portions can be connected to the support body 4121. In this way, the plurality of connecting portions 4122 can support the support body 4121 above the board body 411. Understandably, the support body 4121 is spaced apart from the board body 411 in the Z-axis direction.

[0134] The main board support 412 can further include an extension portion 4123. The extension portion 4123 extends from the support body 4121 in a direction close to the camera support 52. Understandably, the extension portion 4123 protrudes relative to the support body 4121 in a direction close to the camera support 52.

[0135] In some examples, the number of extension portions 4123 can be equal to the number of notches provided on the camera support 52. Each extension portion 4123 is correspondingly accommodated in a notch. In other examples, the number of extension portions 4123 can be greater than the number of notches provided on the camera support 52. A plurality of extension portions 4123 can be located in one notch.

[0136] In the embodiments of the present application, the main board support 412 is accommodated in the notch through the extension portion 4123, which can limit the position of the camera support 52 in the X-axis direction and the Y-axis direction from moving. In addition, the extension portion 4123 abuts against the bottom wall of the notch, on the one hand, the camera support 52 can support the main board support 412 through the extension portion 4123; on the other hand, the main board support 412 can provide downward pressure to the camera support 52 through the extension portion 4123 to limit the position of the camera support 52 in the Z-axis direction. In this way, the main board support 412 can reliably fix the camera support 52 on the board body 411.

[0137] Because the extension portion 4123 is accommodated in the notch, there is interference between the camera support 52 and the main board support 412 in the Z-axis direction. Compared with the case where the extension portion 4123 abuts against the top of the camera support 52 when the camera support 52 has no notch, the space volume occupied by the camera support 52 and the main board support 412 in the Z-axis direction can be reduced.

[0138] In addition, compared with the prior art, the plate body 411 and the camera support 52 are respectively connected by a special component to fix the camera support 52 on the plate body 411, and the embodiment of the application can save the special component and realize the function of fixing the camera support 52 on the plate body 411 by modifying the camera support 52 (opening a gap) and the mainboard support 412 (providing an extension 4123), thereby saving the space occupied by the special component for the electronic device, and thus facilitating the thin and light design of the electronic device.

[0139] On the other hand, the mainboard support 412 can further include a spring piece 4124. The spring piece 4124 can be welded at a welding point of the support body 4121. The spring piece 4124 is used to be electrically connected with a deco metal in the smart phone 100 to conduct the deco metal and the ground.

[0140] The spring piece 4124 can extend downward, and the gap Q of the camera support 52 can be arranged below the spring piece, so that the camera support 52 avoids the spring piece 4124 through the gap Q. In this way, the spring piece 4124 above the gap does not affect the function of the spring piece 4124, and in the case that the camera support 52 and the spring piece 4124 interfere with each other in the height direction of the smart phone 100, the height of the mainboard support 412 can be prevented from being increased to avoid the spring piece 4124, thereby facilitating the thinning of the smart phone 100.

[0141] In the embodiment of the application, the position of the gap Q is not limited. It can be understood that the gap Q can be at any one or more of the first wall body 511, the second wall body 512, the third wall body 513 and the fourth wall body 514.

[0142] However, since the camera support 52 is provided with a gap, unstable contact is easily formed between the camera 51 and the camera support 52. This is because the size of the gap in the height (Z-axis) direction changes according to actual needs, and the conductive foam and the metal spring piece cannot follow the change of the gap height, so the conductive foam and the metal spring piece cannot be used in the camera support 52.

[0143] In addition, the components inside the camera support 52 electrically connecting the camera 51 and the camera support 52 need to provide stable support force to the camera 51 to accurately define the camera 51 in the installation position and avoid eccentricity and other problems, and facilitate the assembly or disassembly between the camera 51 and the camera support 52. When the conductive foam is arranged in the camera support 52, the elasticity of the conductive foam will be weakened and the electrical connection effect will be lost after multiple assembly or disassembly between the camera 51 and the camera support 52. Or, the adhesive force between the conductive foam and the camera support 52 is insufficient, so that the conductive foam is separated from the camera support 52. When the metal spring is arranged in the camera support 52, the friction between the metal spring and the camera support 52 will increase due to the change of the relative position between the camera 51 and the camera support 52 during the assembly or disassembly between the camera 51 and the camera support 52, which will cause the metal spring to damage the metal outer surface of the camera 51 or grind off the metal plating of the metal spring, and will weaken or even lose the electrical connection effect between the camera 51 and the camera support 52.

[0144] Therefore, the conductive foam or the metal spring is not suitable for the modified camera support 52.

[0145] The specific structure of the camera module 50 will be described in detail below to explain how to achieve stable contact between the camera 51 and the camera support 52 in the camera module 50, so that the third harmonic generated between the camera 51 and the camera support 52 is within the permitted range of RSE test, and the interference of the third harmonic generated between the camera 51 and the camera support 52 to the internal electronic devices of the electronic device is reduced or even eliminated.

[0146] It should be noted that the connection between the camera 51 and the camera support 52 in the camera module 50 is only used as an example for description below, and the connection between the speaker unit and the speaker support in the actual speaker module can also refer to the connection mode between the camera 51 and the camera support 52. In addition, the connection mode between the camera 51 and the camera support 52 can also be referred to in other suitable functional modules.

[0147] Figure 9 Fig. 1 shows a top view of a camera module in some embodiments of the present application; Figure 10 Fig. 2 shows a perspective view of the camera module in some embodiments of the present application; Figure 9 Fig. 3 shows a perspective view of the connection between the second wall body and the second frame edge in some embodiments of the present application. Fig. 4 shows a perspective view of the connection between the second wall body and the second frame edge in some embodiments of the present application. Figure 9 Fig. 5 shows a perspective view of the connection between the second wall body and the second frame edge in some embodiments of the present application. Figure 10 As shown in Figs. 1-5, the camera module 50 can include a camera 51 and a camera support 52. In the X-Y plane, the camera 51 is assembled inside the camera support 52.

[0148] As shown in Figs. 1-5, the camera module 50 can include a camera 51 and a camera support 52. In the X-Y plane, the camera 51 is assembled inside the camera support 52. Figure 9As shown, the first wall 511, the second wall 512, the third wall 513, and the fourth wall 514 of the camera 51 form an integral structure. Understandably, when the fourth wall 514 is subjected to pressure and moves, the second wall 512 will move synchronously with the fourth wall 514.

[0149] The fourth wall 514 may include plastic material or metal material, and the embodiments of this application are not limited thereto.

[0150] The fourth frame edge 524 of the camera bracket 52 can contact the fourth wall 514 and form a first interaction force. The second frame edge 522 of the camera bracket 52 can contact the second wall 512 to form a conductive path.

[0151] The fourth frame edge 524 can contact the fourth wall 514, forming a first interaction force. This first interaction force includes the pressure (action force) provided by the fourth wall 514 to the fourth frame edge 524, and the pressure (reaction force) provided by the fourth frame edge 524 to the fourth wall 514 to maintain its shape and position. Since both the fourth frame edge 524 and the fourth wall 514 are subjected to forces, the fourth wall 514 can be referred to as the first force-bearing part, and the fourth frame edge 524 can be referred to as the second force-bearing part.

[0152] The second frame edge 522 of the camera bracket 52 can contact the second wall 512 to form a conductive path. Understandably, both the second frame edge 522 and the second wall 512 are conductive components. Therefore, the second wall 512 can be referred to as the first conductive part, and the second frame edge 522 can be referred to as the second conductive part.

[0153] For example, both the second wall 512 and the second frame edge 522 include conductive metal. For instance, the second wall 512 and the second frame edge 522 may include metals with good conductivity such as nickel, gold, and tungsten.

[0154] The second wall 512 may include a first main body 5121 and a first protruding rib 5122. The first protruding rib 5122 extends from the first main body 5121 toward the second frame edge 522. The second frame edge 522 of the camera bracket 52 contacts the first protruding rib 5122.

[0155] Among them, such as Figure 10 As shown, the length direction of the first protruding rib 5122 can be parallel to the Z-axis direction, and the height direction of the first protruding rib 5122 can be parallel to the X-axis direction. The extension height of the first protruding rib 5122 can be greater than the distance between the first main body 5121 and the second frame edge 522. For example, as... Figure 9 As shown, in the X-axis direction, the size of the first protruding rib 5122 is slightly larger than the distance between the first main body 5121 and the second frame edge 522.

[0156] It can be understood that the first protruding rib 5122 and the second frame edge 522 of the camera holder 52 form an interference fit, forming a second interaction force. The second interaction force includes the pressure (action force) of the second frame edge 522 on the first protruding rib 5122, and the pressure (reaction force) provided by the first protruding rib 5122 to the second frame edge 522 to maintain its shape and position. Among them, the greater the interference amount between the first protruding rib 5122 and the second frame edge 522, the greater the second interaction force between the first protruding rib 5122 and the second frame edge 522.

[0157] Because the length of the first protruding rib 5122 in the direction parallel to the Z axis is relatively long, even if the notch Q is located at the second frame edge 522, the top edge of the second frame edge 522 sinks, and the corresponding top edge of the first protruding rib 5122 in contact with the second frame edge 522 can sink synchronously with the top edge of the second frame edge 522. The extension length of the first protruding rib 5122 after the top edge sinks can still ensure that the interference fit between the first protruding rib 5122 and the second frame edge 522 is formed, and the second interaction force is formed.

[0158] In this embodiment, because the first protruding rib 5122 and the second frame edge 522 of the camera holder 52 form an interference fit, the second wall body 512 and the second frame edge 522 can also include an alloy with low surface treatment requirements. The low surface treatment requirement can mean that the alloy surface forms an oxide film, a film, and other surface film layers. For example, the second wall body 512 and the second frame edge 522 can include suitable alloys such as magnesium alloys, aluminum alloys, stainless steels, etc. Because the first protruding rib 5122 and the second frame edge 522 form an interference fit, the friction between the first protruding rib 5122 and the second frame edge 522 is large during the process of assembling the camera 51 to the camera holder 52, which can damage the oxide film and other surface film layers formed on the surface of the alloy, so that the surface film layer will not affect the stable contact between the first protruding rib 5122 and the second frame edge 522 to form a conductive path.

[0159] In this way, the second interaction force between the second frame edge 522 and the first protruding rib 5122 can ensure stable contact between the second frame edge 522 and the first protruding rib 5122, and can avoid the phenomenon that the second frame edge 522 and the first protruding rib 5122 are not in contact, and reduce or even eliminate the interference of the third harmonic generated between the second wall body 512 and the second frame edge 522 to the internal electronic devices of the smart phone.

[0160] Exemplarily, since the first protruding rib 5122 increases the contact pressure between the second wall body 512 and the second frame edge 522, according to formula (1), the greater the contact pressure between the second wall body 512 and the second frame edge 522, the smaller the third harmonic wave generated between the second wall body 512 and the second frame edge 522. Therefore, the first protruding rib 5122 can reduce or even eliminate the interference of the third harmonic wave generated between the second wall body 512 and the second frame edge 522 on the internal electronic devices of the smart phone.

[0161] Secondly, by setting the first protruding rib 5122 in contact with the second frame edge 522, the second wall body 512 can reduce the contact area between the second wall body 512 and the second frame edge 522, thereby reducing the friction between the second wall body 512 and the second frame edge 522 during assembly or disassembly. In this way, the assembly and disassembly between the camera 51 and the camera support 52 can be facilitated.

[0162] Exemplarily, the width dimension of the first protruding rib 5122 in the Y-axis direction can be greater than or equal to 1.2 mm and less than or equal to 1.8 mm. Exemplarily, the width dimension of the first protruding rib 5122 in the Y-axis direction can be equal to 1.2 mm, 1.4 mm, 1.5 mm, 1.6 mm, or 1.8 mm.

[0163] The second frame edge 522 and the first protruding rib 5122 are in interference fit, which can also absorb the assembly tolerance between the camera 51 and the camera support 52, so that the assembly reliability between the camera 51 and the camera support 52 is higher. Exemplarily, the ideal tolerance distance between the second frame edge 522 and the second wall body 512 after the assembly of the camera 51 and the camera support 52 in the X-axis direction should be 1.5 mm, and the size of the first protruding rib 5122 should be 1.8 mm. However, due to the generation of assembly tolerance, the actual distance between the second frame edge 522 and the second wall body 512 in the X-axis direction after the actual assembly of the camera 51 and the camera support 52 is 1.6 mm. At this time, the first protruding rib 5122 can still be in interference fit with the second frame edge 522, thereby preventing the assembly tolerance between the camera 51 and the camera support 52 from damaging the stable contact between the second frame edge 522 and the second wall body 512, and improving the assembly reliability between the camera 51 and the camera support 52.

[0164] Similarly, the second frame edge 522 is in interference fit with the first protruding rib 5122, and can also absorb the structural tolerance of the camera 51 and / or the structural tolerance of the camera holder 52, so that the assembly reliability between the camera 51 and the camera holder 52 is higher. For example, the ideal structural size of the camera 51 in the X-axis direction is 8.5 mm, and the tolerance distance between the second frame edge 522 and the first main body part 5121 should be 1.5 mm. However, due to the structural tolerance of the camera 51, the actual structural size of the camera 51 in the X-axis direction is 8.44 mm, resulting in that the actual tolerance distance between the second frame edge 522 and the first main body part 5121 is 1.56 mm. At this time, the first protruding rib 5122 can still be in interference fit with the second frame edge 522, thereby preventing the assembly tolerance between the camera 51 and the camera holder 52 from damaging the stable contact between the second wall body 512 and the second frame edge 522, and improving the assembly reliability between the camera 51 and the camera holder 52.

[0165] Figure 11 Another top view of the camera module in some embodiments of the present application is shown.

[0166] Figure 11 The embodiment shown is different from the embodiment shown in Figure 9 and Figure 10 in that, Figure 11 In the embodiment shown, the second wall body 512 does not include the first protruding rib 5122, but the second frame edge 522 includes a second main body part 5221 and a second protruding rib 5222, the second protruding rib 5222 extending from the second main body part 5221 towards the second wall body 512. The second wall body 512 of the camera 51 is in contact with the second protruding rib 5222 and forms an interference fit.

[0167] Figure 11 The structure and function of the second protruding rib 5222 in the embodiment shown can be similar to those of the first protruding rib 5122 in the embodiment shown in Figure 9 and Figure 11 The principle of forming the second interaction force between the second frame edge 522 and the second wall body 512 in the embodiment shown is the same as that of forming the interaction force between the second frame edge 522 and the second wall body 512 in the embodiment shown in Figure 9 Correspondingly, Figure 11 the embodiment shown has Figure 9 the beneficial effects of the embodiment shown.

[0168] Because the second rib 5222 is relatively long in the direction parallel to the Z-axis, even when the notch Q is located at the second frame edge 522, the sinking of the top edge of the second frame edge 522 will allow the top edge of the second rib 5222 to sink synchronously with the top edge of the second frame edge 522. The extension length of the second rib 5222 after the top edge sinks can still ensure an interference fit with the second wall 512, forming a second interaction force.

[0169] Figure 12 Another top view of the camera module in some embodiments of this application is shown. Figure 12 The illustrated embodiments and Figure 9 and Figure 11 The difference between the embodiments shown is that, Figure 12 In the illustrated embodiment, the second wall 512 includes a first main body 5121 and a first rib 5122, and the second frame edge 522 includes a second main body 5221 and a second rib 5222. The first rib 5122 and the second rib 5222 are offset in the Y-axis direction.

[0170] Figure 12 The structure and function of the first rib 5122 in the illustrated embodiment can be compared with... Figure 9 The first rib 5122 in the illustrated embodiment has the same structure and function; Figure 12 The structure and function of the second rib 5222 in the illustrated embodiment can be compared with... Figure 11 In the embodiment shown, the structure and function of the second rib 5222 are the same, and will not be described again here. Figure 12 The principle of the second interaction force formed between the second frame edge 522 and the second wall 512 in the embodiment shown can be referred to Figure 9 and Figure 11 The illustrated embodiment demonstrates the principle of the second interaction force formed between the second frame edge 522 and the second wall 512. Correspondingly, Figure 12 The illustrated embodiment has Figure 9 and Figure 11 The beneficial effects of the illustrated embodiments.

[0171] In other embodiments, such as Figure 9 , Figure 11 and Figure 12 As shown, the first frame edge 521 of the camera bracket 52 can contact the first wall 511 and form a third interaction force. Furthermore, the way the first frame edge 521 and the first wall 511 form the third interaction force is the same as the principle by which the fourth frame edge 524 and the fourth wall 514 form the first interaction force. Since both the first wall 511 and the first frame edge 521 are subjected to force, the first wall 511 can be referred to as the third force-bearing part, and the first frame edge 521 can be referred to as the fourth force-bearing part.

[0172] The third frame edge 523 of the camera holder 52 can be in contact with the third wall body 513 and form a fourth interaction force. The third frame edge 523 and the third wall body 513 can form the fourth interaction force in the same way as the second frame edge 522 and the second wall body 512 form the second interaction force. Correspondingly, the third frame edge 523 and the third wall body 513 can also stably contact to form a conductive path. It can be understood that the third frame edge 523 and the third wall body 513 are both conductive components. Therefore, the third wall body 513 can be referred to as a third conductive part, and the third frame edge 523 can be referred to as a fourth conductive part.

[0173] In this way, Figure 9 , Figure 11 and Figure 12 In the embodiment shown in FIG. 5, the second frame edge 522 and the second wall body 512 stably contact to form a conductive path, and the third frame edge 523 and the third wall body 513 stably contact to form a conductive path, when the camera 51 is assembled inside the camera holder 52.

[0174] Figure 13 FIG. 6 shows a top view of a camera module in another embodiment of the present application. Figure 13 The embodiment shown in FIG. 6 is different from the embodiment shown in FIG. 5 in that Figure 12 The embodiment shown in FIG. 6 is different from the embodiment shown in FIG. 5 in that Figure 13 In the embodiment shown in FIG. 6, the second wall body 512 does not include the first protruding rib 5122, and the second frame edge 522 does not include the second protruding rib 5222. Figure 13 In the embodiment shown in FIG. 6, the camera module 50 further includes an elastic member 53. The elastic member 53 can be located between the fourth wall body 514 and the fourth frame edge 524.

[0175] The elastic member 53 can be made of a composite material with elastic deformation capability, such as rubber, plastic, silicone, spring steel, etc., and the embodiments of the present application do not limit this.

[0176] The fourth wall body 514 abuts against the fourth frame edge 524 through the elastic member 53 to form a first interaction force. The first interaction force includes the pressure (action force) provided by the fourth wall body 514 to the elastic member 53, the pressure (reaction force) provided by the elastic member 53 to the fourth wall body 514 to maintain its shape and position, the pressure (action force) provided by the fourth frame edge 524 to the elastic member 53, and the pressure (reaction force) provided by the elastic member 53 to the fourth frame edge 524 to maintain its shape and position.

[0177] The pressure provided by the elastic member 53 to the fourth wall body 514 is actually the pressure provided by the elastic member 53 to the camera 51. After the camera 51 is subjected to the pressure, the camera 51 has a tendency to move close to the second frame edge 522, thereby pressing the second frame edge 522. The camera 51 pressing the second frame edge 522 forms a second interaction force between the second wall body 512 of the camera 51 and the second frame edge 522. The second interaction force includes the pressure (action force) of the second wall body 512 to the second frame edge 522, and the pressure (reaction force) of the second frame edge 522 to the second wall body 512 to maintain the shape and position of the second frame edge 522. The size of the second interaction force depends on the pressure provided by the elastic member 53 to the fourth wall body 514. The greater the pressure provided by the elastic member 53 to the fourth wall body 514, the greater the second interaction force.

[0178] Exemplarily, due to the pressure provided by the elastic member 53 to the camera 51, the contact pressure between the second wall body 512 and the second frame edge 522 is increased. According to formula (1), the greater the contact pressure between the second wall body 512 and the second frame edge 522, the smaller the third harmonic wave generated between the second wall body 512 and the second frame edge 522. Therefore, the elastic member 53 can reduce or even eliminate the interference of the third harmonic wave generated between the second wall body 512 and the second frame edge 522 to the internal electronic devices of the smart phone.

[0179] In this way, the second interaction force between the second frame edge 522 and the second wall body 512 can ensure stable contact between the second frame edge 522 and the second wall body 512, and can avoid the phenomenon that the second frame edge 522 and the second wall body 512 are not in contact. The interference of the third harmonic wave generated between the second wall body 512 and the second frame edge 522 to the internal electronic devices of the smart phone can be reduced or even eliminated.

[0180] In some embodiments, the elastic member 53 can include an elastic body part 531 and an elastic protruding part 532. The elastic protruding part 532 can extend outward from the elastic body part 531.

[0181] The length direction in which the elastic protruding part 532 extends can be parallel to the Z-axis direction, and the height direction in which the elastic protruding part 532 extends can be parallel to the X-axis direction. The extension height of the elastic protruding part 532 can be greater than the distance between the elastic body part 531 and the fourth wall body 514.

[0182] In some examples, as shown in Figure 13 The elastic body part 531 can be located on the surface of the fourth frame edge 524 close to the fourth wall body 514, and the elastic protruding part 532 extends in the direction close to the fourth wall body 514. The extension end of the elastic protruding part 532 in the X-axis direction is in contact with the fourth wall body 514 and forms an interference fit.

[0183] The elastic protrusion 532 is in contact with the fourth wall body 514 and forms an interference fit. For reference, FIG. 6A shows a schematic view of the fourth wall body 514 and the elastic protrusion 532, where (a) shows a state in which the elastic protrusion 532 is not in contact with the fourth wall body 514, and (b) shows a state in which the elastic protrusion 532 is in contact with the fourth wall body 514 and forms an interference fit. Figure 14 Figure 14 (a) of FIG. 6A shows a state in which the elastic protrusion 532 is not in contact with the fourth wall body 514. Figure 14 (b) of FIG. 6A shows a state in which the elastic protrusion 532 is in contact with the fourth wall body 514 and forms an interference fit. Figure 14 As can be seen from (b) of FIG. 6A, the fourth wall body 514 provides pressure to the elastic protrusion 532, so that the elastic protrusion 532 is deformed and compressed, and the elastic protrusion 532 provides pressure to the fourth wall body 514.

[0184] For example, the interference amount between the elastic protrusion 532 and the fourth wall body 514 can be equal to 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, or 0.1 mm.

[0185] When the interference amount between the elastic protrusion 532 and the fourth wall body 514 is small, the first interaction force formed between the fourth wall body 514 and the fourth frame edge 524 is small, which is not conducive to the stable contact between the second frame edge 522 and the second wall body 512. When the interference amount between the elastic protrusion 532 and the fourth wall body 514 is large, the second interaction force formed between the fourth wall body 514 and the fourth frame edge 524 is small, which is easy to damage the camera holder 52.

[0186] Since the length of the elastic protrusion 532 in the direction parallel to the Z-axis is relatively long, even if the notch Q is located at the fourth frame edge 524 and the top edge of the fourth frame edge 524 is sunken, the top edge of the elastic protrusion 532 can sink synchronously with the top edge of the fourth frame edge 524. The extension length of the elastic protrusion 532 after the top edge is sunken can still ensure that the interference fit is formed between the elastic protrusion 532 and the fourth frame edge 524, and the first interaction force is formed.

[0187] The shape of the elastic protrusion 532 can be a hemisphere, a circular truncated cone, a polygonal prism, a trapezoidal body, or other suitable three-dimensional shapes, which are not limited in the embodiments of the present application.

[0188] In some examples, as shown in FIG. 6B, the fourth frame edge 524 can be provided with a first groove K1. The opening of the first groove K1 faces the fourth wall body 514. The elastic main body 531 can be partially or entirely received in the first groove K1. Figure 13

[0189] ​​By receiving part of the elastic member 53 in the first groove K1, the problem that the space between the fourth wall body 514 and the fourth frame edge 524 is insufficient to accommodate the elastic member 53 due to the internal space restriction of the smart phone 100 can be overcome. The elastic member 53 can provide pressure to the camera 51, so as to form a second interaction force between the second frame edge 522 and the second wall body 512, to ensure stable contact between the second frame edge 522 and the second wall body 512, to avoid the phenomenon that the second frame edge 522 and the second wall body 512 are not in contact, and to reduce or even eliminate the interference of the third harmonic generated between the second wall body 512 and the second frame edge 522 on the internal electronic devices of the smart phone.

[0190] In addition, the elastic protruding part 532 is in interference fit with the fourth wall body 514, and can also absorb the assembly tolerance between the camera 51 and the camera support 52, so that the assembly reliability between the camera 51 and the camera support 52 is higher. Similarly, the elastic protruding part 532 is in interference fit with the fourth wall body 514, and can also absorb the structural tolerance of the camera 51 and / or the structural tolerance of the camera support 52, so that the assembly reliability between the camera 51 and the camera support 52 is higher. The principle of the elastic protruding part 532 absorbing the assembly tolerance between the camera 51 and the camera support 52, and the principle of the elastic protruding part 532 absorbing the structural tolerance of the camera 51 and / or the structural tolerance of the camera support 52 can be referred to the principle of the first protruding rib 5122 absorbing the assembly tolerance between the camera 51 and the camera support 52, and the principle of the elastic protruding part 532 absorbing the structural tolerance of the camera 51 and / or the structural tolerance of the camera support 52, which will not be described here.

[0191] Figure 15 Another top view of the camera module in some other embodiments of the application is shown.

[0192] Figure 15 The shown embodiment is different from the embodiment shown in Figure 13 The shown embodiment is different from the embodiment shown in Figure 15 In the shown embodiment, the elastic main body part 531 can be located on the surface of the fourth wall body 514 close to the fourth frame edge 524, but not on the surface of the fourth frame edge 524 close to the fourth wall body 514. The elastic protruding part 532 extends towards the fourth frame edge 524. The extension end of the elastic protruding part 532 in the X-axis direction is in contact with the fourth frame edge 524 and forms an interference fit.

[0193] In some examples, the fourth wall body 514 can be provided with a second groove K2. The opening of the second groove K2 faces the fourth frame edge 524. The elastic main body part 531 can be partially or entirely received in the second groove K2.

[0194] Figure 15The principle of forming the first interaction force between the fourth frame edge 524 and the fourth wall body 514 in the embodiment shown is the same as Figure 13 The principle of forming the second interaction force between the second frame edge 522 and the second wall body 512 in the embodiment shown is the same as Figure 15 The embodiment shown has Figure 13 The embodiment shown has the beneficial effects.

[0195] Figure 16 Another plan view of the camera module in some other embodiments of the present application is shown.

[0196] In some other embodiments, as shown, the first frame edge 521 of the camera holder 52 can be in contact with the first wall body 511 and form a third interaction force. And the way in which the first frame edge 521 and the first wall body 511 form the third interaction force can be the same as the way in which the fourth frame edge 524 and the fourth wall body 514 form the first interaction force. Figure 16 The third frame edge 523 of the camera holder 52 can be in contact with the third wall body 513 and form a fourth interaction force. And the way in which the third frame edge 523 and the third wall body 513 form the fourth interaction force can be the same as the way in which the second frame edge 522 and the second wall body 512 form the second interaction force. Correspondingly, the third frame edge 523 and the third wall body 513 can also be in stable contact to form a conductive path.

[0197] In this way,

[0198] In the embodiment shown, when the camera 51 is assembled inside the camera holder 52, the second frame edge 522 and the second wall body 512 are in stable contact to form a conductive path, and the third frame edge 523 and the third wall body 513 are in stable contact to form a conductive path. Figure 16

[0199] Another plan view of the camera module in some other embodiments of the present application is shown. Figure 17 The embodiment shown and Figure 17 The difference between the embodiment shown and Figure 16 The camera module 50 includes a resilient member 53, which provides pressure to the camera 51 while the second wall body 512 is in contact with the second frame edge 522 using the first protruding rib or the second frame edge 522 is in contact with the second wall body 512 using the second protruding rib, and forms an interference fit.

[0200] It can be understood that Figure 17 The embodiment shown can be Figure 16 The embodiment shown and Figure 9 The embodiments shown are combined with each other.

[0201] In some examples, as shown in FIG. 5A, the elastic member 53 includes an elastic body portion 531 and two elastic protruding portions 532a and 532b. The fourth frame edge 524 can be provided with a first recess K1, and the elastic body portion 531 can be partially or wholly received in the first recess K1. The elastic protruding portion 532a is in interference fit with the camera 51 and provides a first pressure to the fourth wall body 514 of the camera 51. The elastic protruding portion 532b is also in interference fit with the camera 51 and provides a second pressure to the fourth wall body 514 of the camera 51. Figure 17

[0202] The second wall body 512 can include a first body portion 5121 and a first protruding rib 5122. The first protruding rib 5122 extends from the first body portion 5121 towards the second frame edge 522. The second frame edge 522 of the camera holder 52 is in contact with the first protruding rib 5122 and forms an interference fit.

[0203] The first pressure provided by the elastic protruding portion 532a to the camera 51 and the second pressure provided by the elastic protruding portion 532b to the camera 51 can increase the second interaction force between the second frame edge 522 and the first protruding rib 5122, thereby improving the stability of the contact between the second frame edge 522 and the first protruding rib 5122. The phenomenon of the second frame edge 522 being in contact with the second wall body 512 can be avoided, and the interference of the third harmonic generated between the second wall body 512 and the second frame edge 522 with the internal electronic devices of the smartphone can be reduced or even eliminated.

[0204] Figure 18 Another top view of the camera module in some other embodiments of the present application is shown.

[0205] In some other examples, as shown in FIG. 5B, the elastic member 53 includes an elastic body portion 531 and two elastic protruding portions 532a and 532b. The second frame edge 522 can include a second body portion 5221 and two second protruding ribs 5222a and 5222b. The second protruding rib 5222a can be located on a straight line along the extension height direction of the elastic protruding portion 532a, and the second protruding rib 5222b can be located on a straight line along the extension height direction of the elastic protruding portion 532b. Figure 18 In this way, the pressure provided by the elastic protruding portion 532a to the fourth wall body 514 can be located on the same straight line as the second interaction force between the second wall body 512 and the second protruding rib 5222a. In this way, the pressure provided by the elastic protruding portion 532a to the fourth wall body 514 can be more efficient in increasing the second interaction force between the second wall body 512 and the second protruding rib 5222a, thereby improving the stability of the contact between the second wall body 512 and the second protruding rib 5222a.

[0206] In this way, the pressure provided by the elastic protruding portion 532a to the fourth wall body 514 can be located on the same straight line as the second interaction force between the second wall body 512 and the second protruding rib 5222a. In this way, the pressure provided by the elastic protruding portion 532a to the fourth wall body 514 can be more efficient in increasing the second interaction force between the second wall body 512 and the second protruding rib 5222a, thereby improving the stability of the contact between the second wall body 512 and the second protruding rib 5222a.​

[0207] Similarly, the pressure provided by the elastic protruding part 532b to the fourth wall body 514 can be in the same line with the second interaction force between the second wall body 512 and the second protruding rib 5222b. The stability of the contact between the second wall body 512 and the second protruding rib 5222b can also be improved.

[0208] In this way, Figure 18 In the example shown, the stability of the contact between the second wall body 512 and the second protruding rib 5222a is high, and the stability of the contact between the second wall body 512 and the second protruding rib 5222b is high. The phenomenon that the second frame edge 522 is not in contact with the second wall body 512 can be avoided, and the interference of the third harmonic generated between the second frame edge 522 and the second wall body 512 on the internal electronic devices of the smart phone can be reduced or even eliminated.

[0209] In addition, the elastic member 53 is in contact with the camera 51 through the two elastic protruding parts 532a and 532b, and the second frame edge 522 is in contact with the camera 51 through the two second protruding ribs 5222a and 5222b, so that the force on the camera 51 is more balanced, and the problems such as eccentricity, centrifugation and rotation of the camera 51 can be prevented, the reliability of the assembly of the camera 51 and the camera support 52 is ensured, and the yield of the smart phone 100 is improved.

[0210] In other embodiments, as Figure 18 As shown, the first frame edge 521 of the camera support 52 can be in contact with the first wall body 511 and form a third interaction force. In addition, the way in which the first frame edge 521 and the first wall body 511 form the third interaction force can be the same as the way in which the fourth frame edge 524 and the fourth wall body 514 form the first interaction force.

[0211] The third frame edge 523 of the camera support 52 can be in contact with the third wall body 513 and form a fourth interaction force. In addition, the way in which the third frame edge 523 and the third wall body 513 form the fourth interaction force can be the same as the way in which the second frame edge 522 and the second wall body 512 form the second interaction force. Correspondingly, the third frame edge 523 and the third wall body 513 can also stably contact to form a conductive path.

[0212] In this way, Figure 18 In the embodiment shown, when the camera 51 is assembled inside the camera support 52, the second frame edge 522 and the second wall body 512 stably contact to form a conductive path, and the third frame edge 523 and the third wall body 513 stably contact to form a conductive path.

[0213] Figure 19 Another top view of a camera module in some embodiments of the present application is shown.

[0214] Figure 19 The embodiment shown in Figure 18 The embodiment shown in the difference between the first wall 511 and the first frame edge 521 between the elastic member, and the fourth wall 514 and the fourth frame edge 524 between the elastic member is connected to form an integral structure. The integral structure can include a plurality of elastic convex portions 532c, 532d and 532e. Among them, the extension height direction of the elastic convex portion 532c can be parallel to the X axis, and the fourth wall 514 is in contact and forms an interference fit. The extension height direction of the elastic convex portion 532e can be parallel to the Y axis, and the first wall 511 is in contact and forms an interference fit.

[0215] The extension height direction of the elastic convex portion 532d can form an angle α with the X axis direction. The angle of the angle α can be greater than 30° and less than 60°. For example, the angle of the angle α is 30°, 40°, 45°, 50° or 60°. The extension end of the elastic convex portion 532d is in contact with the connection of the first wall 511 and the fourth wall 514, and forms an interference fit.

[0216] The elastic convex portion 532d can provide a pressure F to the camera 51. The pressure F can include a first component Fx parallel to the X axis direction and a second component Fy parallel to the Y axis direction. The first component Fx extrudes the camera 51, which can increase the second interaction force between the second wall 512 and the second frame edge 522. The second component Fy extrudes the camera 51, which can increase the fourth interaction force between the third wall 513 and the third frame edge 523.

[0217] Since the first component Fx or the component Fy is less than the pressure F provided by the elastic convex portion 532d to the camera 51. Therefore, the interference amount between the elastic convex portion 532d and the camera 51 can be greater than the interference amount between the elastic convex portion 532c or 532e and the camera 51. In this way, the first component Fx of the pressure provided by the elastic convex portion 532d to the camera 51 can be close to the pressure provided by the elastic convex portion 532c to the camera 51; or the second component Fy of the pressure provided by the elastic convex portion 532d to the camera 51 can be close to the pressure provided by the elastic convex portion 532e to the camera 51.

[0218] In this way, Figure 19 In the embodiment shown, when the camera 51 is assembled inside the camera holder 52, the second frame edge 522 and the second wall 512 are in stable contact to form a conductive path, and the third frame edge 523 and the third wall 513 are in stable contact to form a conductive path.

[0219] Figure 20 It is shown Figures 13 to 19 The embodiment shown in the three-dimensional structure diagram of the elastic member.

[0220] AsFigure 20 As shown, the bottom of the elastic protrusion 532 can be ramp-shaped. The ramp-shaped bottom has the smallest dimension in the X-axis direction, and the ramp-shaped top has the largest dimension in the X-axis direction. The ramp-shaped bottom is closer to the end of the back cover 20, and the ramp-shaped top is closer to the end of the screen 10.

[0221] In this way, during assembly of the camera 51 and the camera holder 52, the camera 51 can be assembled into the camera holder 52 along the ramp. During initial assembly of the camera 51 and the camera holder 52, the pressure between the camera 51 and the elastic protrusion 532 is small, thereby facilitating entry of the camera 51 into the camera holder 52 and improving the assembly efficiency of the smart phone 100.

[0222] Figure 21 FIG. 6 shows a top view of a camera module in some embodiments of the present application. Figure 21 The embodiments shown in FIGS. 5A and 5B are different from the embodiments shown in FIGS. 4A and 4B in that Figure 12 The embodiments shown in FIGS. 5A and 5B are different from the embodiments shown in FIGS. 4A and 4B in that Figure 21 In the embodiments shown in FIGS. 5A and 5B, the second wall 512 does not include the first protruding rib 5122, and the second frame 522 does not include the second protruding rib 5222. Figure 21 In the embodiments shown in FIGS. 5A and 5B, the camera module 50 further includes an elastic conductor 54. The elastic conductor 54 can be located between the second wall 512 and the second frame 522.

[0223] The elastic conductor 54 can include an elastic material and a conductive layer covering the entire outer surface of the elastic material. The conductive layer can be obtained by metallization treatment on the surface of the elastic material. The elastic material can include rubber (such as silicone rubber), plastic, silica gel, spring steel, and other composite materials with elastic deformation capability. The conductive layer can include a nickel plating layer, a gold plating layer, a tungsten plating layer, and other metal plating layers, which have excellent electrical conductivity. The embodiments of the present application do not limit the specific materials of the elastic material and the conductive layer.

[0224] For example, the hardness of the rubber can be greater than or equal to 68 HA and less than or equal to 92 HA; the stretch resistance of the rubber can be greater than or equal to 60 pounds and less than or equal to 75 pounds; and the resilience of the rubber can be greater than or equal to 0.2 N and less than or equal to 0.8 N. For example, the hardness of the rubber can be 68 HA, 70 HA, 75 HA, 80 HA, 85 HA, 90 HA, or 92 HA. For another example, the stretch resistance of the rubber can be 60 pounds, 63 pounds, 65 pounds, 67 pounds, 68 pounds, 70 pounds, 74 pounds, or 75 pounds. For yet another example, the resilience of the rubber can be 0.2 N, 0.3 N, 0.4 N, 0.5 N, 0.6 N, 0.7 N, or 0.8 N.

[0225] The length direction in which the elastic conductor 54 extends can be parallel to the Z-axis direction, and the height direction in which the elastic conductor 54 extends can be parallel to the X-axis direction. The extension height of the elastic conductor 54 can be greater than the distance between the second wall body 512 and the second frame edge 522.

[0226] The elastic conductor 54 can simultaneously be in interference fit with the second wall body 512 and the second frame edge 522. For example, when the camera 51 is assembled to the camera holder 52, the second wall body 512 of the camera 51 is spaced apart from the second frame edge 522 of the camera holder 52 by 0.8 mm. The size of the elastic conductor 54 in the X-axis direction is 1.5 mm, and by arranging the elastic conductor 54 between the second wall body 512 and the second frame edge 522, the elastic conductor 54 can simultaneously be in interference fit with the second wall body 512 and the second frame edge 522.

[0227] When the elastic conductor 54 is in interference fit with the second wall body 512 and the second frame edge 522, the elastic conductor 54 provides a pressure to the camera 51, and the camera 51 forms a tendency to move close to the fourth frame edge 524, thereby forming a first interaction force between the fourth wall body 514 of the camera 51 and the fourth frame edge 524 of the camera holder 52. The first interaction force includes a pressure (action force) of the fourth wall body 514 on the fourth frame edge 524, and a pressure (reaction force) of the fourth frame edge 524 on the fourth wall body 514 to maintain the shape and position of the fourth frame edge 524.

[0228] The second wall body 512 can form a second interaction force with the second frame edge 522 through the elastic conductor 54. The second interaction force includes a pressure (action force) of the second wall body 512 on the elastic conductor 54, a pressure (reaction force) of the elastic conductor 54 on the second wall body 512 to maintain the shape and position of the elastic conductor 54, a pressure (action force) of the elastic conductor 54 on the second frame edge 522, and a pressure (reaction force) of the second frame edge 522 on the elastic conductor 54 to maintain the shape and position of the second frame edge 522.

[0229] Since the elastic conductor 54 has a long length in the direction parallel to the Z-axis, even if the notch Q is located at the second frame edge 522, the top edge of the elastic conductor 54 can sink synchronously with the top edge of the second frame edge 522. The extension length of the elastic conductor 54 after the top edge sinks can still ensure that the elastic conductor 54 is in interference fit with the second wall body 512 and the second frame edge 522, and forms the second interaction force.

[0230] In this way, the second wall 512 and the elastic conductor 54 can be in stable contact, and a conductive path is formed between the second wall 512 and the conductive layer on the elastic conductor 54. The second frame edge 522 can also be in stable contact with the elastic conductor 54, and a conductive path is formed between the second frame edge 522 and the conductive layer on the elastic conductor 54. Therefore, the second wall 512, the elastic conductor 54, and the second frame edge 522 together form a conductive path.

[0231] It should be noted that the number of elastic conductors 54 can be one or more. The structure of each elastic conductor 54 is basically the same.

[0232] In some examples, the elastic conductor 54 may include a conductive body portion 541 and a conductive protrusion portion 542. The conductive protrusion portion 542 may extend outward from the conductive body portion 541.

[0233] In some embodiments, such as Figure 21 As shown, the conductive main body 541 can be located on the surface of the second frame edge 522 near the second wall 512, and the conductive protrusion 542 extends in the direction close to the second wall 512. The extended end of the conductive protrusion 542 in the X-axis direction contacts the second wall 512 and forms an interference fit.

[0234] The conductive protrusion 542 can be in the shape of a hemisphere, a frustum, a polygonal prism, a trapezoid, or other suitable three-dimensional shape. The embodiments of this application do not limit this.

[0235] In some examples, such as Figure 21 As shown, a third groove K3 may be formed in the second frame edge 522. The opening of the third groove K3 faces the second wall 512. The conductive main body 541 may be partially or completely housed in the third groove K3.

[0236] By housing part of the elastic conductor 54 within the third groove K3, the problem that the space between the second wall 512 and the second frame edge 522 is insufficient to accommodate the elastic conductor 54 due to the internal space constraints of the smartphone 100 can be overcome. This allows the elastic conductor 54 to provide pressure to the camera 51, thereby forming a second interaction force between the second frame edge 522 and the second wall 512. This ensures stable contact between the second frame edge 522, the elastic conductor 54, and the second wall 512, avoiding a partial contact between the second frame edge 522 and the second wall 512, and reducing or even eliminating the interference of the third harmonic generated between the second wall 512 and the second frame edge 522 on the internal electronic components of the smartphone.

[0237] In addition, the elastic conductive body 54 is in interference fit with both the second wall body 512 and the second frame edge 522, and can also absorb assembly tolerance between the camera 51 and the camera holder 52, so that assembly reliability between the camera 51 and the camera holder 52 is higher. Similarly, the elastic conductive body 54 is in interference fit with both the second wall body 512 and the second frame edge 522, and can also absorb structural tolerance of the camera 51 and / or structural tolerance of the camera holder 52, so that assembly reliability between the camera 51 and the camera holder 52 is higher. The principle that the elastic conductive body 54 absorbs assembly tolerance between the camera 51 and the camera holder 52 and the principle that the elastic protruding portion 532 absorbs structural tolerance of the camera 51 and / or structural tolerance of the camera holder 52 can refer to the principle that the first protruding rib 5122 absorbs assembly tolerance between the camera 51 and the camera holder 52 and the principle that the elastic protruding portion 532 absorbs structural tolerance of the camera 51 and / or structural tolerance of the camera holder 52, which will not be described here.

[0238] In other embodiments, the conductive main body portion 541 in the elastic conductive body 54 can be located on a surface of the second wall body 512 close to the second frame edge 522, and the conductive protruding portion 542 extends towards the second frame edge 522. The conductive protruding portion 542 contacts the second frame edge 522 at an extension end in the X-axis direction and forms an interference fit.

[0239] Figure 22 Another top view of a camera module in some embodiments of the present application is shown.

[0240] In yet other examples, as shown in Figure 22 The smart phone also includes an external grounding member 70. The external grounding member 70 can be located on a side of the second frame edge 522 away from the second wall body 512. The external grounding member 70 can be electrically connected with a grounding point of the main circuit board 41. The elastic conductive body 54 can include a conductive main body portion 541 and two conductive protruding portions 542a, 542b. The two conductive protruding portions can extend outward from the conductive main body portion 541, and the two conductive protruding portions 542a, 542b are respectively disposed on both sides of the conductive main body portion 541 in the X-axis direction.

[0241] The conductive main body 541 can be embedded in the second frame edge 522, the conductive protruding part 542a extends from the second frame edge 522 to the direction close to the second wall body 512 and is in interference fit with the second wall body 512, and the conductive protruding part 542b extends from the second frame edge 522 to the direction close to the external grounding part 70 and is in interference fit with the external grounding part 70. Since the conductive main body 541 can be embedded in the second frame edge 522, the conductive protruding part 542a is in interference fit with the second wall body 512, the second interaction force is formed between the second frame edge 522 and the second wall body 512, and the fifth interaction force is formed between the second frame edge 522 and the external grounding part 70. The elastic conductive body 54 can ensure the stable contact between the second wall body 512 and the external grounding part 70.

[0242] Figure 22 In the embodiment shown, the elastic conductive body 54 can form a conductive path between the second wall body 512 inside the camera holder 52 and the external grounding part 70 outside the camera holder 52, thereby reducing or even eliminating the interference of the third harmonic generated between the second wall body 512, the second frame edge 522 and the external grounding part 70 on the internal electronic devices of the smart phone.

[0243] Figure 23 A perspective structural schematic diagram of the camera holder in various embodiments of the application is shown; Figure 24 Another perspective structural schematic diagram of the camera holder in various embodiments of the application is shown.

[0244] As shown in Figure 23 and Figure 24 The camera holder 52 further includes a grounding part 525 on the basis of the first frame edge 521, the second frame edge 522, the third frame edge 523 and the fourth frame edge 524. One end of the grounding part 525 can be connected to a target frame edge, and the other end of the grounding part 525 can be connected to an external grounding point. The target frame edge can be any one of the first frame edge 521, the second frame edge 522, the third frame edge 523 and the fourth frame edge 524.

[0245] The external grounding point can include a grounding point of the plate body 411, a grounding point on the middle frame (metal middle frame) 30 or a grounding point on some decorative metal, and the embodiments of the application do not limit this.

[0246] As shown in Figure 23 One end of the grounding part 525 can be connected to the outer side surface of the first frame edge 521, and the extension direction of the grounding part 525 can be parallel to the Y-axis direction. Alternatively, as shown in Figure 24 One end of the grounding part 525 can be connected to the outer side surface of the first frame edge 521, and the extension direction of the grounding part 525 can be parallel to the X-axis direction.

[0247] In some other embodiments, one end of the grounding component 525 can also be connected to the inner side surface of the first frame edge 521. Embodiments of the present application do not limit this.

[0248] It should be noted that the first interaction force and the second interaction force between the camera 51 and the camera holder 52 can exist at the same time. The first interaction force and the second interaction force are positively correlated. Understandably, the greater the first interaction force, the greater the second interaction force, so that stable contact between the first conductive part and the second conductive part can be achieved, and the interference of the third harmonic generated between the camera 51 and the camera holder 52 on the internal electronic devices of the smart phone can be reduced or even eliminated.

[0249] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any change or replacement within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
