Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a fixing structure of a camera decoration and a shell in an electronic device. Background Art

[0002] With the development of electronic devices such as mobile phones and tablet computers, users have put forward higher and higher requirements on the appearance of electronic devices. In electronic devices with cameras, camera decorations are the main components set on the shell to fix and protect the camera. With the trend of electronic devices becoming thinner and lighter, how to design the fixing method of the camera decoration and the shell so that the reliable fixing between the camera decoration and the shell can be achieved is a topic that the industry continues to explore. Summary of the invention

[0003] The embodiments of the present application provide an electronic device, which can realize reliable assembly and fixation between a decorative part and a housing under the trend of lightweight and thin development of electronic devices.

[0004] The present application provides an electronic device, the electronic device comprising:

[0005] A back cover, wherein the back cover has a mounting hole, the mounting hole is a through hole, and the back cover includes a first surface facing the outside of the electronic device and a second surface facing the inside of the electronic device;

[0006] A camera decoration, wherein the camera decoration is installed in the installation hole; wherein the camera decoration comprises:

[0007] a first connection portion connected to the first surface;

[0008] a second connection portion connected to one end of the first connection portion, the second connection portion passing through the mounting hole and connected to an inner wall of the mounting hole, and an end of the second connection portion away from the first connection portion being located inside the electronic device;

[0009] as well as

[0010] an extension portion connected to an end of the second connection portion away from the first connection portion, wherein at least a portion of the extension portion is protruding relative to an outer peripheral surface of the second connection portion;

[0011] a light-transmitting hole, the light-transmitting hole penetrating the first connecting portion and the second connecting portion along a thickness direction of the electronic device; and

[0012] A limiting member, wherein the limiting member is fixedly connected to the second connecting portion or the extending portion, and the limiting member is clamped between the second surface and the extending portion.

[0013] It is understandable that, since the first connection portion is configured to be located on the outside of the electronic device and connected to the first surface of the back cover, the first connection portion can block the portion of the camera module that extends out of the back cover, so that when the camera module is large and protrudes relative to the back cover, the camera decoration piece can also be applied to the smaller mounting hole opening of the back cover. Since the second connection portion and the extension portion are located on the inner side of the first connection portion, the first connection portion can block the second connection portion and the extension portion. When the camera decoration piece is installed in the mounting hole of the back cover, only the first connection portion is exposed to the outside of the electronic device, while the second connection portion and the extension portion are hidden inside the electronic device, making the overall visual effect of the electronic device more simple.

[0014] When the camera decoration is installed in place in the mounting hole of the back cover, the second connection part and the extension part of the camera decoration both extend into the storage space of the electronic device, and the extension part can be used as the folding edge of the second connection part and be set at an angle with the second connection part. By setting the folding edge, a certain overlap amount can be made between the folding edge and the back cover, so that when the limiter is assembled on the camera decoration, the limiter is located in the gap area between the back cover and the extension part. Since the limiter can be connected to the back cover and the extension part respectively on both sides perpendicular to the back cover, the back cover and the extension part can cooperate to limit the movement of the limiter in the direction perpendicular to the back cover, further fixing the position of the limiter.

[0015] In the prior art, the camera decoration and the back cover are assembled only by bonding, which can easily lead to the risk of the camera decoration falling off if the glue dispensing process is not properly controlled. In the embodiment of the present application, by adding a limiter between the extension part and the back cover, the first connection part can be connected to the first surface of the back cover through the limiter, and the second connection part can be connected to the mounting hole of the back cover. The limiter acts as a barrier to prevent the camera decoration from moving along the second surface of the back cover toward the first surface and detaching from the back cover. This further enhances the connection stability between the camera decoration and the back cover and the installation stability of the camera decoration, avoids the displacement and falling of the camera decoration, and realizes reliable assembly and fixation between the camera decoration and the back cover.

[0016] In a possible implementation manner, the limiting member is connected to the periphery of the second connecting portion along the circumferential direction of the second connecting portion, the limiting member is arranged around a portion of the outer circumference of the second connecting portion, and the limiting member is engaged with the second connecting portion.

[0017] The limiting piece is clamped and fixed to the second connecting part so that the limiting piece is fixedly connected to the camera decorative piece, thereby making use of the fastening performance of the limiting piece, and preventing the relative position between the camera decorative piece and the camera module from changing easily, which is beneficial to further improve the position stability of the camera decorative piece, preventing the camera decorative piece from slipping off the back cover, and improving reliability.

[0018] In a possible embodiment, the limiting member includes a main body and a protrusion, the main body is connected to the second connecting portion, the protrusion is arranged on the surface of the main body away from the back cover, the protrusion is spaced apart from the extension portion, and the main body can be separated from or clamped with the second connecting portion through the protrusion.

[0019] It is understandable that the convex portion provided on the body can be used as a clamping structure in the stopper. During the assembly process of the stopper and the camera decorative piece, the staff can conveniently use a special tool to install the stopper on the camera decorative piece, or remove the stopper from the camera decorative piece.

[0020] In a possible embodiment, the camera decoration includes a plurality of the extension parts and a plurality of the limiting parts, the plurality of the extension parts are arranged at intervals along the circumferential direction of the second connecting part, each of the limiting parts is clamped with one of the extension parts, and each of the limiting parts is clamped between the second surface and one of the extension parts.

[0021] In a possible implementation manner, one end of the second connection portion connected to the first connection portion is the first end of the second connection portion, and one end of the second connection portion away from the first connection portion is the second end of the second connection portion;

[0022] The second connecting portion is provided with a receiving groove, and the receiving groove is recessed from the end surface of the second end toward the direction of the first end;

[0023] The extension portion is fixedly connected to the groove wall of the receiving groove, part of the extension portion is located in the receiving groove, and part of the limiting member is located in the receiving groove and is clamped with the extension portion.

[0024] Since the receiving groove formed by the recess of the second connecting part can accommodate part of the extension part, part of the extension part can be located inside the second connecting part and part of it can be located outside the second connecting part. Compared with setting the entire extension part outside the second connecting part, the space occupied by the extension part in the receiving space can be further reduced and it can be ensured that the extension part has a sufficient extension length.

[0025] In a possible embodiment, the limiting member includes a first limiting portion, a second limiting portion and a third limiting portion, the first limiting portion and the second limiting portion are respectively bent and connected to both sides of the third limiting portion, the first limiting portion and the second limiting portion are arranged opposite to each other, the first limiting portion, the second limiting portion and the third limiting portion form a slot, and the slot is used to clamp with the extension portion.

[0026] Under this setting, the fastening performance of the limiter can be utilized to prevent the relative position between the camera decoration and the camera module from changing easily, which is beneficial to further improve the position stability of the camera decoration, prevent the camera decoration from slipping off the back cover, and improve reliability.

[0027] In a possible implementation manner, the accommodating groove includes a top wall, a first side wall, and a second side wall, and the first side wall and the second side wall are respectively connected to two sides of the top wall;

[0028] The extension portion includes a first portion and a second portion, the first portion is located in the receiving groove and connected to the top wall, the second portion is located outside the receiving groove, and the orthographic projection of the second portion on the rear cover falls into the rear cover;

[0029] The first portion and the first side wall form a first holding space, and the first portion and the second side wall form a second holding space;

[0030] Part of the first limiting portion is located in the first holding space, part of the second limiting portion is located in the second holding space, and the third limiting portion is sandwiched between the second portion and the back cover.

[0031] In a possible implementation manner, at least a portion of an orthographic projection of the limiting member on the back cover falls within a range of an orthographic projection of the first connecting portion on the back cover.

[0032] Therefore, the structure of the limiter can be selected according to the actual application scenario of the electronic device, which has high flexibility.

[0033] In a possible implementation manner, the orthographic projection of the first connecting portion on the back cover covers a portion of the orthographic projection of the limiting member on the back cover;

[0034] The electronic device further comprises a diaphragm, wherein the diaphragm is located between the second surface of the rear cover and the limiting member;

[0035] The diaphragm completely covers the limiting member, or the diaphragm at least covers the protruding portion of the limiting member relative to the first connecting portion along the radial direction of the camera decorative member.

[0036] It is understandable that, since part of the area of ​​the stopper exceeds the outer edge of the first connection part, when the part of the stopper exceeding the outer edge of the first connection part is partially arched and a large pushing force is applied to the back cover, it is easy to cause visible defects such as visible film marks or screen marks on the appearance of the back cover. Among them, the film mark can be understood as the mark on the back cover caused by being directly or indirectly lifted by the stopper.

[0037] In a possible implementation, the electronic device further includes an adhesive layer, wherein the adhesive layer is located in a gap region between the mounting hole and the second connecting portion, and the adhesive layer is connected between an inner wall of the mounting hole and an outer peripheral surface of the second connecting portion.

[0038] It is understandable that when the adhesive layer is set in the gap area between the second connection part and the mounting hole, the hot melt adhesive at high temperature and in liquid state can be injected into the gap. The liquid hot melt adhesive has good fluidity and can fill the gap between the second connection part and the mounting hole. After the hot melt adhesive is cooled and solidified, a solid adhesive layer can be formed. The adhesive layer can achieve a sealed connection between the camera decorative part and the inner wall of the mounting hole. This way of setting the adhesive layer is conducive to improving the bonding strength and bonding sealing between the adhesive layer and the mounting hole and the camera decorative part, thereby improving the connection reliability and installation stability between the camera decorative part and the back cover.

[0039] In a possible implementation manner, the first connecting portion, the second connecting portion and the extending portion of the camera decoration are an integrated structure.

[0040] It is understandable that in the prior art, the camera decoration is usually an internal and external split structure, and the multiple parts of the camera decoration located inside and outside the back cover are assembled together by screws. However, since there are assembly tolerances between the multiple parts in this camera decoration, the thickness of the electronic device will increase. At the same time, in order to avoid interference between the camera decoration and the camera module in the XY plane, the size of the mounting hole will also be larger. In the embodiment of the present application, the camera decoration is an internal and external integrated structure, so it can avoid the additional space occupied and assembly tolerance caused by the assembly of parts, which is conducive to reducing the thickness of the electronic device and better adapting to the development trend of miniaturization and thinness of electronic equipment.

[0041] In a possible implementation, the electronic device further includes a decorative sheet, the first connecting portion of the camera decorative piece includes a third surface facing the outside of the electronic device and a fourth surface facing the inside of the electronic device, the first connecting portion is provided with a receiving groove, and the receiving groove is recessed from the third surface toward the fourth surface; wherein,

[0042] The decorative sheet is fixed in the receiving groove.

[0043] It is understandable that the decorative sheet can block the openings of the receiving groove and the light-transmitting hole in the camera decorative component to ensure the sealing performance of the electronic device and prevent external impurities from entering the light-transmitting hole and affecting the imaging quality of the electronic device.

[0044] In a possible implementation manner, the light-transmitting hole is communicated with the receiving groove, and the decorative sheet closes the opening of the light-transmitting hole;

[0045] The electronic device further comprises a camera module, one end of which is located in the light-transmitting hole and protrudes relative to the first surface of the back cover.

[0046] The camera module itself is relatively thick and can be configured to protrude relative to the first surface of the back cover. In this way, the electronic device is thicker at the position corresponding to the camera module relative to other positions, and the camera module partially protrudes from the back cover and is partially located in the receiving space of the electronic device.

[0047] In a possible implementation manner, the electronic device further includes a sealing member, wherein the sealing member is located between the first connecting portion and the first surface of the back cover.

[0048] It is understandable that during the use of electronic devices, there is a possibility that the electronic devices are exposed to dust and water environments. For example, when using electronic devices on rainy days, rain may wet the electronic devices; or, during the washing process, the electronic devices may accidentally fall into the water. In these scenarios, impurities such as water and dust outside the electronic device may enter the interior of the electronic device through the gap between the camera decorative part and the back cover, affecting the normal use of the electronic device. Therefore, by providing a sealing part between the first connecting part and the back cover, it is possible to seal the gap between the camera decorative part and the back cover on the basis of achieving good connection performance between the first connecting part and the back cover, thereby improving the overall sealing performance of the electronic device and having better reliability.

[0049] In a possible implementation manner, the back cover includes a glass cover plate and a coating layer that are stacked, and the coating layer is located on a side of the glass cover plate that faces the interior of the electronic device.

[0050] The glass cover is usually transparent or translucent, and the coating layer can present various colors so that users can see these colors through the glass cover, thereby making the back cover have a variety of appearance effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] The specific implementation of the present application will be clearly described below in conjunction with the accompanying drawings.

[0071] The embodiment of the present application provides an electronic device. The electronic device may be, but is not limited to, a mobile phone, a tablet computer, a laptop computer, a wearable device, etc. The wearable device may be a smart bracelet, a smart watch, a smart head-mounted display, smart glasses, etc.

[0072] The following description will be made by taking a mobile phone as an example of an electronic device, but it should be understood that the present application is not limited thereto.

[0073] Please refer to Figure 1 and Figure 2 , Figure 1 An exemplary electronic device 200 according to an embodiment of the present application is shown. Figure 2 Shows Figure 1 The exemplary assembly structure of the back cover assembly 100 and the camera module 230 of the exemplary electronic device 200 is shown.

[0074] In the embodiments of the present application, for the convenience of illustration, as shown in the figures, the length direction of the electronic device 200 is defined as the X direction, the width direction of the electronic device 200 is defined as the Y direction, and the thickness direction of the electronic device 200 is defined as the Z direction. The X direction, the Y direction, and the Z direction are perpendicular to each other.

[0075] The electronic device 200 may include a frame 210, a display module 220, a back cover assembly 100 and a camera module 230. The display module 220 and the back cover assembly 100 are respectively arranged on opposite sides of the frame 210. The assembled display module 220, the frame 210 and the back cover assembly 100 can form an internal receiving space W of the electronic device 200, and the receiving space W can accommodate other parts of the electronic device 200, such as multiple modules, multiple electronic devices and multiple structural parts for completing various functions of the electronic device 200. In some embodiments, as the thickness of the electronic device 200 becomes thinner and thinner, the camera module 230 may be partially located in the receiving space W and partially protrude from the back cover assembly 100. Specifically, the camera module 230 may be a rear camera of the electronic device 200 for capturing static images or dynamic videos.

[0076] For example, when the electronic device 200 is a mobile phone, the frame 210 may be the middle frame of the mobile phone, and the display module 220 may be a cover plate for displaying visual information such as images, colors, and texts for the user, for example, a display screen. The back cover assembly 100 may be the back cover of the mobile phone, and the back cover may be an integrally formed cover plate or a cover plate formed by splicing multiple parts, which is not limited in this application.

[0077] Please refer to Figure 3 , Figure 4 , Figure 5a and Figure 5b , Figure 3 yes Figure 2 A partial view of an exemplary assembly structure is shown, Figure 4 yes Figure 3 An exploded view of an exemplary assembly structure is shown, Figure 5a is along Figure 3 An exemplary cross-sectional view obtained by the dashed line AA in FIG. Figure 5b Shows Figure 5a The assembly structure in each figure may include a back cover assembly 100 and a camera module 230. Further, the back cover assembly 100 may include a back cover 10, a camera decorative member 20, a stopper 30, an adhesive layer 40 and a decorative sheet 50.

[0078] The back cover 10 is arranged on the side of the frame 210 away from the display module 220. The back cover 10 and the frame 210 can be either an integrally formed structure or connected by methods such as welding, bonding, and clamping. The material of the back cover 10 may include glass, and the glass material has little obstruction to signal transmission, which can effectively reduce the interference of the back cover 10 on the transmission signal. In addition, the curvature of the glass is large, which can make the design of the back cover 10 smoother, make the electronic device 200 feel smoother, and improve the appearance of the electronic device 200. At the same time, the glass material is a non-conductive material, and an inductor coil can be added to the inner surface of the back cover 10 to realize the wireless charging function of the electronic device 200. In other embodiments, the material of the back cover 10 may also include metal, plastic or ceramic, which is not strictly limited.

[0079] In a possible implementation, please refer to Figure 5a and Figure 5b The back cover 10 may include a glass cover plate 11 and a coating layer 12 which are stacked, and the coating layer 12 is located on the side of the glass cover plate 11 facing the receiving space W. The glass cover plate 11 is generally transparent or translucent. The coating layer 12 may present various colors so that the user can see these colors through the glass cover plate 11, thereby enabling the back cover 10 to have a variety of appearance effects.

[0080] Exemplarily, the coating layer 12 may include a plurality of dielectric layers (not shown), through which light may interfere with light waves to present different colors. Depending on the thickness of the dielectric layer and the type of material, the coating layer 12 can present different colors. The specific structure of the coating layer 12 may be selected according to the actual application requirements of the back cover 10 to achieve the diversification of the appearance of the electronic device 200. For example, the coating layer 12 may be designed to have various color effects, such as gradient colors or reflections, so that the color of the back cover 10 in the electronic device 200 is richer for different users to choose from.

[0081] In an embodiment of the present application, the back cover 10 may include a first surface 101 and a second surface 102 relative to each other, the first surface 101 being the surface of the back cover 10 exposed to the external environment, that is, the appearance surface of the electronic device 200, and the second surface 102 being the surface of the back cover 10 facing the receiving space W. The back cover 10 may have a mounting hole 103. The mounting hole 103 is generally a through hole, that is, the mounting hole 103 passes through the first surface 101 and the second surface 102 of the back cover 10 along the Z direction and communicates with the receiving space W of the electronic device 200, and the mounting hole 103 may be used to install the camera decoration 20. Exemplarily, the shape of the mounting hole 103 may be circular, square or irregular. Exemplarily, the back cover 10 may have one or more mounting holes 103. When the back cover 10 has one mounting hole 103, the camera decoration 20 may be installed in the mounting hole 103. When the back cover 10 has a plurality of mounting holes 103 , the camera decoration 20 can be installed in the plurality of mounting holes 103 at the same time; or, a separate camera decoration 20 can be installed in each mounting hole 103 .

[0082] The following description will be made by taking an example that the rear cover 10 has only one mounting hole 103 and the camera decoration 20 is installed in the one mounting hole 103 , but it should be understood that the invention is not limited thereto.

[0083] Please refer to Figure 4 , Figure 5a and Figure 5b The camera module 230 itself is relatively thick and can be configured to protrude relative to the first surface 101 of the rear cover 10. In this way, the electronic device 200 is thicker at the position corresponding to the camera module 230 relative to other positions. Figure 5b The camera module 230 may include a bracket 2310 and a lens 2320 , wherein the lens 2320 is fixedly connected to the bracket 2310 , and an end of the lens 2320 away from the bracket 2310 protrudes relative to the first surface 101 of the back cover 10 .

[0084] In order to protect the camera module 230 and improve the overall aesthetics of the electronic device 200, a camera decoration 20 needs to be provided on the back cover 10. In the electronic device 200, the camera decoration 20 is located around the camera module 230, and is used to separate the camera module 230 from the external environment, and can ensure that the corresponding functions are achieved through the camera module 230 while also playing a role in decorating the appearance of the electronic device 200, thereby improving the aesthetics of the electronic device 200 in the camera module 230 area.

[0085] The camera decoration 20 can be installed in the installation hole 103 of the back cover 10. A portion of the camera decoration 20 can be located on the side of the back cover 10 facing the external environment to protect the lens 2320 of the camera module 230, and another portion of the camera decoration 20 can be located in the installation hole 103 of the back cover 10 and on the side of the back cover 10 facing the receiving space W.

[0086] In the embodiment of the present application, the camera decoration 20 may be an integrated structure formed by an integrated molding method. Alternatively, the camera decoration 20 may include multiple parts, and the multiple parts may be formed into an integrated structure by welding, bonding, clamping, etc., and the present application does not impose strict restrictions on this.

[0087] It is understandable that in the prior art, the camera decoration is usually an internal and external split structure, and the multiple parts of the camera decoration located inside and outside the back cover are assembled together by screws. However, since there are assembly tolerances between the multiple parts in this camera decoration, the thickness of the electronic device will increase. At the same time, in order to avoid interference between the camera decoration and the camera module in the XY plane, the size of the mounting hole will also be larger. In the embodiment of the present application, the camera decoration 20 is an internal and external integrated structure, so it can avoid the additional space occupied and assembly tolerance caused by the assembly of parts, which is conducive to reducing the thickness of the electronic device 200 and better adapting to the development trend of miniaturization and thinness of the electronic device 200.

[0088] Exemplarily, compared with the existing architectural scheme, the thickness of the electronic device using the embodiment of the present application (i.e., the length of the electronic device along the Z direction) can be reduced by 0.1mm-0.2mm (including the endpoint values ​​0.1mm and 0.2mm). The material of the camera decoration 20 can be any metal material such as aluminum, gold, silver, copper, iron, stainless steel, aluminum alloy, titanium alloy, or an alloy material composed of multiple metal materials. Alternatively, the material of the camera decoration 20 can be a non-metallic material, for example, it can be any non-metallic material such as ceramic, rubber, glass, plastic, graphite, or a synthetic material composed of multiple non-metallic materials. The following will be explained using the example of the camera decoration 20 being made of metal, but it should be understood that the present application is not limited to this.

[0089] Please refer to Figure 5a , Figure 5b , Figure 6a and Figure 6b , Figure 6a-6b Shown from two angles Figure 3 The camera decoration 20 in the exemplary assembly structure shown. The camera decoration 20 may include a first connection portion 21, a second connection portion 22 and an extension portion 23. Among them, the first connection portion 21, the second connection portion 22 and the extension portion 23 may be an integrated structure formed by an integrated molding method. The first connection portion 21 is located on the side of the back cover 10 facing the external environment (i.e., the side of the first surface 101 of the back cover 10), and the first connection portion 21 protrudes relative to the first surface 101 of the back cover 10. The second connection portion 22 is connected to one end of the first connection portion 21, the second connection portion 22 passes through the mounting hole 103 and is connected to the inner wall of the mounting hole 103, and the end of the second connection portion 22 away from the first connection portion 21 is located in the receiving space W. The extension portion 23 is connected to the end of the second connection portion 22 away from the first connection portion 21, and the extension portion 23 is located on the side of the back cover 10 facing the receiving space W (i.e., the side of the second surface 102 of the back cover 10).

[0090] The first connection part 21 may include a third surface 211 and a fourth surface 212. The third surface 211 of the first connection part 21 is a surface of the first connection part 21 facing the outside of the electronic device 200, and the fourth surface 212 of the first connection part 21 is a surface of the first connection part 21 facing the inside of the electronic device 200. The first connection part 21 is provided with a receiving groove 213, which is recessed from the third surface 211 of the first connection part 21 to the inside of the first connection part 21. The receiving groove 213 is used to place the decorative sheet 50, so that the camera decorative piece 20 cooperates with the decorative sheet 50 to achieve the appearance decoration effect of the electronic device 200 and the protection effect of the camera module 230. Exemplarily, the shape of the first connection part 21 may be a hollow ring.

[0091] In a possible implementation, Figure 5a and Figure 5bAs shown, the outer diameter of the first connection part 21 is larger than the aperture size of the mounting hole 103, and the first connection part 21 is connected to the first surface 101 of the back cover 10. It is understandable that since the camera decoration 20 protrudes from the back cover 10, when the electronic device 200 is bumped or dropped, the camera decoration 20 is susceptible to the impact force from the outer side of the back cover 10 and may fall off or shift from the back cover 10. In this embodiment, the first connection part 21 and the back cover 10 have a certain overlap and fixed connection at the edge of the mounting hole, so that the back cover 10 can provide a certain support for the camera decoration 20. When the camera decoration 20 is subjected to the impact force from the outer side of the back cover 10, the camera decoration 20 can be effectively prevented from falling off, thereby effectively improving the installation reliability and stability of the camera decoration 20.

[0092] In this embodiment, the electronic device 200 may further include a sealant 240, which is disposed between the first connection portion 21 and the first surface 101 of the back cover 10. Exemplarily, the sealant 240 may be a sealant, and the sealant 240 bonds the first connection portion 21 and the back cover 10. At the same time, the sealant 240 may be elastic, so that during the assembly process of the camera decorative member 20 and the back cover 10, a rigid collision between the first connection portion 21 and the back cover 10 can be avoided.

[0093] Furthermore, during the use of the electronic device 200, the electronic device 200 may be exposed to dust or water. For example, when the electronic device 200 is used on a rainy day, the rain may wet the electronic device 200; or, during the washing process, the electronic device 200 may accidentally fall into the water. In these scenarios, impurities such as water and dust outside the electronic device 200 may enter the interior of the electronic device 200 through the gap between the camera decoration 20 and the back cover 10, affecting the normal use of the electronic device 200. Therefore, by providing a seal 240 between the first connecting portion 21 and the back cover 10, it is possible to seal the gap between the camera decoration 20 and the back cover 10 on the basis of achieving good connection performance between the first connecting portion 21 and the back cover 10, thereby improving the overall sealing performance of the electronic device 200 and having better reliability.

[0094] Please continue reading Figure 5a , Figure 5b , Figure 6a and Figure 6b, the second connection part 22 is connected to the first connection part 21, the center line of the second connection part 22 coincides with the center line of the first connection part 21, and the second connection part 22 and the first connection part 21 are arranged in sequence in the Z direction. The second connection part 22 may include a first end 221 and a second end 222, the first end 221 of the second connection part 22 is an end of the second connection part 22 connected to the first connection part 21, the second end 222 of the second connection part 22 is an end of the second connection part 22 away from the first connection part 21, and the first end 221 of the second connection part 22 is connected to the second connection part 22. When the camera decoration 20 is assembled with the back cover 10, the second connection part 22 passes through the mounting hole 103 of the back cover 10 and is connected to the inner wall of the mounting hole 103, the second end 222 of the second connection part 22 is located in the receiving space W of the electronic device 200, and the second connection part 22 is located in the mounting hole 103 of the back cover 10 and the receiving space W of the electronic device 200 as a whole. Exemplarily, the shape of the second connection part 22 may be a hollow ring.

[0095] The outer diameter of the second connection part 22 is smaller than the hole diameter of the mounting hole 103, and there is a gap between the second connection part 22 and the mounting hole 103. The gap between the second connection part 22 and the mounting hole 103 is provided with an adhesive layer 40. The adhesive layer 40 connects the inner wall of the mounting hole 103 and the outer peripheral surface of the second connection part 22. Exemplarily, the adhesive layer 40 can be a glue layer.

[0096] It is understandable that when the adhesive layer 40 is set in the gap area between the second connection part 22 and the mounting hole 103, the hot melt adhesive at high temperature and in liquid state can be injected into the gap. The liquid hot melt adhesive has good fluidity and can fill the gap between the second connection part 22 and the mounting hole 103. After the hot melt adhesive is cooled and solidified, a solid adhesive layer 40 can be formed. The adhesive layer 40 can achieve a sealed connection between the camera decorative part 20 and the inner wall of the mounting hole 103. This way of setting the adhesive layer 40 is conducive to improving the bonding strength and bonding sealing between the adhesive layer 40 and the mounting hole 103 and the camera decorative part 20, thereby improving the connection reliability and installation stability between the camera decorative part 20 and the back cover 10.

[0097] Furthermore, the camera decoration 20 may also have a light hole 201 that penetrates the first connection portion 21 and the second connection portion 22 along the Z direction, is connected to the receiving groove 213 , and one end of the lens 2320 away from the bracket 2310 is located in the light hole 201 .

[0098] In the embodiment of the present application, the camera decoration 20 further includes an extension portion 23. The extension portion 23 is connected to the second end 222 of the second connection portion 22, and at least part of the extension portion 23 is protruding relative to the outer peripheral surface of the second connection portion 22. The part of the extension portion 23 protruding relative to the outer peripheral surface of the second connection portion 22 can be arranged in sequence with the second connection portion 22 in the radial direction (i.e., the Y direction) of the camera decoration 20. Exemplarily, a part of the extension portion 23 is located in the second connection portion 22, and another part of the extension portion 23 is protruding relative to the outer peripheral surface of the second connection portion 22. Alternatively, the extension portion 23 is arranged in sequence with the second connection portion 22 in the Z direction as a whole, a part of the extension portion 23 is stacked with the second connection portion 22, and another part of the extension portion 23 is protruding relative to the outer peripheral surface of the second connection portion 22. Alternatively, the extension portion 23 is arranged in sequence with the second connection portion 22 in the Z direction as a whole, and all the extension portions 23 can be protruding relative to the outer peripheral surface of the second connection portion 22. In addition, the camera decoration 20 may include one or more extension portions 23. When the camera decoration 20 includes only one extension 23, the extension 23 may partially or completely surround the circumferential direction of the camera decoration 20. That is, the extension 23 may be annular or arc-shaped. When the camera decoration 20 includes multiple extensions 23, the multiple extensions 23 may be spaced apart in the circumferential direction of the camera decoration 20, and the spacing between the multiple extensions 23 may be the same or different, and the present application does not impose strict restrictions on this. For example, the camera decoration 20 may include three extensions 23, and the three extensions 23 are spaced apart in the circumferential direction of the camera decoration 20. Among the three extensions 23, the spacing between two adjacent extensions 23 may be the same or different.

[0099] When the camera decoration 20 is installed on the back cover 10, the extension 23 is located in the receiving space W of the electronic device 200, and the orthographic projection of the extension 23 in the Z direction has a partial overlapping area with the orthographic projection of the back cover 10 in the Z direction. In addition, there may be a gap between the extension 23 and the back cover 10, and the gap may be used to accommodate the stopper 30.

[0100] Please refer to Figure 5a and Figure 5b, the stopper 30 can be fixedly connected to the second connection portion 22 or the extension portion 23, and at least part of the stopper 30 can be located in the gap area between the back cover 10 and the extension portion 23. The stopper 30 connects the second surface 102 of the back cover 10 with the extension portion 23. Among them, the stopper 30 can be clamped between the second surface 102 of the back cover 10 and the extension portion 23, and has no direct fixing relationship such as bonding, welding, etc. with the second surface 102 of the back cover 10 and the extension portion 23; similarly, the stopper 30 can also be clamped between the second surface 102 of the back cover 10 and the extension portion 23, and has a direct fixing relationship such as bonding, welding, etc. with one or both of the second surface 102 of the back cover 10 and the extension portion 23, and there is no strict restriction on this. Exemplarily, the camera decorative member 20 can have one or more stoppers 30. Specifically, the stopper 30 can be a clamp. For example, the camera decoration 20 may include a stopper 30, which is arranged in the circumferential direction of the camera decoration 20, and is engaged with the second connection portion 22. Alternatively, the camera decoration 20 may include three stoppers 30, which may be arranged at intervals in the circumferential direction of the camera decoration 20, and each stopper 30 is engaged with an extension portion 23 and is sandwiched between the second surface 102 of the rear cover 10 and an extension portion 23. This application does not impose strict restrictions on this.

[0101] It is understandable that, since the first connection portion 21 is configured to be located outside the electronic device 200 and connected to the first surface 101 of the back cover 10, the first connection portion 21 can block the portion of the camera module 230 that extends outside the back cover 10, so that when the camera module 230 is large and protrudes relative to the back cover 10, the camera decoration 20 can also be applied to the smaller mounting hole 103 of the back cover 10. Since the second connection portion 22 and the extension portion 23 are located on the inner side of the first connection portion 21, the first connection portion 21 can block the second connection portion 22 and the extension portion 23. When the camera decoration 20 is installed in the mounting hole 103 of the back cover 10, only the first connection portion 21 is exposed to the outside of the electronic device 200, while the second connection portion 22 and the extension portion 23 are hidden inside the electronic device 200, making the overall visual effect of the electronic device 200 more simple.

[0102] When the camera decoration 20 is installed in place in the installation hole 103 of the back cover 10, the second connection part 22 and the extension part 23 of the camera decoration 20 both extend into the receiving space W of the electronic device 200, and the extension part 23 can be used as the folding edge of the second connection part 22 and is arranged at an angle with the second connection part 22. By setting the folding edge, a certain overlap amount can be provided between the folding edge and the back cover 10, so that when the limiting member 30 is assembled to the camera decoration 20, the limiting member 30 is located in the gap area between the back cover 10 and the extension part 23. Since the limiting member 30 can be connected to the back cover 10 and the extension part 23 respectively on both sides along the direction perpendicular to the back cover 10, the back cover 10 and the extension part 23 can cooperate to limit the movement of the limiting member 30 along the direction perpendicular to the back cover 10 (i.e., the Z direction and the opposite direction of the Z direction), and further fix the position of the limiting member 30.

[0103] In the prior art, the camera decoration and the back cover are assembled only by bonding, which can easily lead to the risk of the camera decoration falling off when the glue dispensing process is not properly controlled. In the embodiment of the present application, by adding a stopper 30 between the extension 23 and the back cover 10, the first connection part 21 can be connected to the first surface 101 of the back cover 10 through the stopper 30, and the second connection part 22 can be connected to the mounting hole 103 of the back cover 10. The stopper 30 acts as a barrier to prevent the camera decoration 20 from moving along the second surface 102 of the back cover 10 toward the first surface 101 (i.e., the Z direction) and detaching from the back cover 10. This further enhances the connection stability between the camera decoration 20 and the back cover 10 and the installation stability of the camera decoration 20, avoids the displacement and falling of the camera decoration 20, and realizes reliable assembly and fixation between the camera decoration 20 and the back cover 10.

[0104] In a possible implementation, please refer to Figure 7 , Figure 8 and Fig. 9 , Figure 7 yes Figure 2 A partial view of another angle of the exemplary assembly structure shown, Figure 8 Shows Figure 7 The exemplary stopper 30 and the camera decoration 20 shown, Fig. 9 Shows Figure 8 An exemplary stop 30 is shown.

[0105] As described above, the camera decoration 20 may include a limiter 30, which extends along the circumferential direction of the second connecting portion 22 and is connected to the periphery of the second connecting portion 22. The limiter 30 may be arc-shaped and arranged around a portion of the outer circumference of the second connecting portion 22. Alternatively, the limiter 30 may be annular and arranged around the entire outer circumference. The limiter 30 is snap-fitted and fixed to the second connecting portion 22 so that the limiter 30 is fixedly connected to the camera decoration 20, so that the fastening performance of the limiter 30 can be utilized, and the relative position between the camera decoration 20 and the camera module 230 is not easy to change, which is conducive to further improving the position stability of the camera decoration 20, making it difficult for the camera decoration 20 to slip off the back cover 10, and having better reliability.

[0106] In addition, in the Z direction, the two sides of the stopper 30 respectively abut against the protruding portion of the extension portion 23 relative to the second connection portion 22 and the second surface 102 of the rear cover 10. Under this arrangement, the movement of the stopper 30 in a direction perpendicular to the rear cover 10 can be limited, so that the position of the stopper 30 is fixed and does not change.

[0107] In this embodiment, if Figure 8 and Fig. 9 As shown, the limiter 30 may include a body 31 and a convex portion 32. The body 31 is connected to the second connecting portion 22, the convex portion 32 is arranged on the surface of the body 31 away from the rear cover 10, and the convex portion 32 is spaced apart from the extension portion 23 to avoid interference between the two. The body 31 can be separated or clamped from the second connecting portion 22 by the convex portion 32. It can be understood that the convex portion 32 provided on the body 31 can serve as a clamping structure in the limiter 30. During the assembly process of the limiter 30 and the camera decoration 20, the staff can easily use special tools to install the limiter 30 on the camera decoration 20, or remove the limiter 30 from the camera decoration 20.

[0108] In another possible implementation, please refer to Figure 6b , Fig.10 , Fig.11 and Fig.12 , Fig.10 yes Figure 2 A partial view from another angle of another exemplary assembly structure shown, Fig.11 Shows Fig.10 The exemplary stopper 30 and the camera decoration 20 shown, Fig.12 Shows Fig.11The exemplary limiting member 30 shown in the figure. Different from the previous embodiment, in this embodiment, the camera decorative member 20 may include multiple limiting members 30, specifically, the camera decorative member 20 may include three limiting members 30, and the three limiting members 30 may be evenly distributed on the second connecting portion 22, so that the multiple limiting members 30 can cooperate to further limit the rotation of the camera decorative member 20 along its circumferential direction. Figure 6b As shown, the camera decoration 20 may include three extensions 23, which may be arranged at intervals in the circumferential direction of the camera decoration 20, and the distance between two adjacent extensions 23 may be the same among the three extensions 23. The second connecting portion 22 may be provided with three receiving grooves 223, which may be arranged at intervals in the circumferential direction of the camera decoration 20, and the distance between two adjacent receiving grooves 223 may be the same among the three receiving grooves 223. Each receiving groove 223 may be used to accommodate a stopper 30 and an extension 23.

[0109] The following description will take the assembly structure of a receiving slot 223, an extension portion 23 and a limit member 30 as an example. The following description of the assembly structure of a receiving slot 223, an extension portion 23 and a limit member 30 can be applied to the assembly structure of the remaining two receiving slots 223, the remaining two extension portions 23 and the remaining two limit members 30.

[0110] The receiving groove 223 is recessed from the end surface of the second end 222 of the second connecting portion 22 toward the first end 221 of the second connecting portion 22. The extension portion 23 is fixedly connected to the groove wall of the receiving groove 223. The extension portion 23 can be partially located in the receiving groove 223, and partially located outside the receiving groove 223 and protruding relative to the outer peripheral surface of the second connecting portion 22, that is, in the radial direction of the camera decorative component 20, part of the extension portion 23 can be protruding relative to the second connecting portion 22. Since the receiving groove 223 formed by the recess of the second connecting portion 22 can accommodate part of the extension portion 23, part of the extension portion 23 can be located inside the second connecting portion 22, and part of it can be located outside the second connecting portion 22. Compared with setting the entire extension portion 23 outside the second connecting portion 22, the space occupied by the extension portion 23 in the receiving space W can be further reduced, and the extension portion 23 can be ensured to have a sufficient extension length.

[0111] Exemplarily, the surface of the extension portion 23 away from the bottom wall of the receiving groove 223 may be flush with the end surface of the second end 222 of the second connecting portion 22, or the surface of the extension portion 23 away from the bottom wall of the receiving groove 223 may be recessed relative to the end surface of the second end 222 of the second connecting portion 22. Alternatively, the surface of the extension portion 23 away from the bottom wall of the receiving groove 223 may be convex relative to the end surface of the second end 222 of the second connecting portion 22.

[0112] In this embodiment, part of the stopper 30 is located in the receiving groove 223 and is engaged with the extension portion 23. Fig.10 , Fig.11 and Fig.12 As shown, the limiting member 30 may include a first limiting portion 33, a second limiting portion 34 and a third limiting portion 35. The first limiting portion 33 and the second limiting portion 34 are respectively bent and connected to both sides of the third limiting portion 35. The first limiting portion 33 and the second limiting portion 34 are relatively arranged. The first limiting portion 33, the second limiting portion 34 and the third limiting portion 35 form a card slot 36. The card slot 36 is clamped with the extension portion 23 to fix the limiting member 30 to the camera decoration 20, so that the fastening performance of the limiting member 30 can be utilized, and the relative position between the camera decoration 20 and the camera module 230 is not easy to change, which is beneficial to further improve the position stability of the camera decoration 20, so that the camera decoration 20 is not easy to slip off the back cover 10, and the reliability is better.

[0113] In a specific application scenario, such as Figure 6b As shown, the receiving groove 223 may include a top wall 2231, a first side wall 2232, and a second side wall 2233. The first side wall 2232 and the second side wall 2233 are respectively connected to both sides of the top wall 2231, and the first side wall 2232 and the second side wall 2233 are arranged opposite to each other in the circumferential direction of the second connecting portion 22. The extension portion 23 may include a first portion 231 and a second portion 232. The first portion 231 is located in the receiving groove 223 and is connected to the top wall 2231. The first portion 231 and the first side wall 2232 form a first holding space Q1, and the first portion 231 and the second side wall 2233 form a second holding space Q2. The second portion 232 is located outside the receiving groove 223, and the orthographic projection of the second portion 232 on the back cover 10 falls into the back cover 10, that is, the orthographic projection of the second portion 232 in the Z direction has a partial overlapping area with the orthographic projection of the back cover 10 in the Z direction. Part of the first limiting portion 33 is located in the first holding space Q1, part of the second limiting portion 34 is located in the second holding space Q2, and the third limiting portion 35 is clamped between the second portion 232 and the back cover 10. The first limiting portion 33, the second limiting portion 34 and the third limiting portion 35 cooperate to hold the first portion 231.

[0114] In the embodiment of the present application, the orthographic projection of the stopper 30 on the back cover 10 may all fall within the range of the orthographic projection of the first connection portion 21 on the back cover 10, that is, the orthographic projection of the stopper 30 in the Z direction all falls within the range of the orthographic projection of the first connection portion 21 in the Z direction. Alternatively, part of the orthographic projection of the stopper 30 on the back cover 10 falls within the range of the orthographic projection of the first connection portion 21 on the back cover 10, that is, the orthographic projection of the stopper 30 in the Z direction and the orthographic projection of the first connection portion 21 in the Z direction have a partial overlapping area.

[0115] In a possible implementation, please refer to Fig.13a and Fig.13b , Fig.13a is along Figure 3 Another exemplary cross-sectional view obtained by the dotted line AA in FIG. Fig.13b Shows Fig.13a Area F in.

[0116] The orthographic projection of the limiter 30 in the Z direction has a partial overlapping area with the orthographic projection of the first connecting portion 21 in the Z direction. In other words, a partial area of ​​the limiter 30 exceeds the outer edge of the first connecting portion 21. The electronic device 200 may also include a diaphragm 250, which is located between the second surface 102 of the back cover 10 and the limiter 30. The orthographic projection of the diaphragm 250 on the back cover 10 completely covers the orthographic projection of the limiter 30 on the back cover 10. Alternatively, the diaphragm 250 at least covers the excess portion of the limiter 30 relative to the first connecting portion 21 (along the radial direction of the camera decorative member 20). Exemplarily, the diaphragm 250 may be a film-proof mylar. Of course, in other embodiments, the orthographic projection of the first connecting portion 21 on the back cover 10 may also be misaligned with the orthographic projection of the limiter 30 on the back cover 10, and there is no strict limitation on this.

[0117] It is understandable that, since part of the area of ​​the stopper 30 exceeds the outer edge of the first connection portion 21, when the part of the stopper 30 that exceeds the outer edge of the first connection portion 21 is partially arched and a large thrust is applied to the back cover 10, it is easy to cause visible defects such as visible film marks or screen marks on the appearance of the back cover 10. Among them, the film mark can be understood as the mark on the back cover 10 caused by being directly or indirectly lifted by the stopper 30.

[0118] Therefore, by adding the diaphragm 250 between the stopper 30 and the back cover 10, when the stopper 30 has a tendency to move toward the back cover 10, the diaphragm 250 can be used as a barrier to directly bear the thrust of the stopper 30 instead of the back cover 10. Since the diaphragm 250 is in direct contact with the stopper 30, the diaphragm 250 can remove most of the thrust of the stopper 30, so that the stopper 30 will not be in direct contact with the back cover 10, which is conducive to reducing or eliminating the film print problem of the appearance of the foldable electronic device 200, reducing the visual defects of the electronic device 200, and improving reliability.

[0119] In the embodiments of this application, please refer to Fig.13a and Fig.13b, the decorative sheet 50 can be installed in the receiving groove 213 of the first connecting part 21, so that the first connecting part 21 can protect the decorative sheet 50. The decorative sheet 50 can cover the light-transmitting hole 201 and have a light-transmitting area, so that the external ambient light can pass through the light-transmitting area of ​​the decorative sheet 50 and reach the lens 2320 of the camera module 230. It can be understood that the decorative sheet 50 can block the opening of the receiving groove 223 and the light-transmitting hole 201 in the camera decorative part 20 to ensure the sealing performance of the electronic device 200 and prevent external impurities from entering the light-transmitting hole 201 and affecting the imaging quality of the electronic device 200.

[0120] For example, the decorative sheet 50 may be a transparent glass plate, which covers the camera decorative piece 20 and exposes part of the structure of the back cover 10, and the transparent glass plate and the camera decorative piece 20 achieve a decorative effect together. The decorative sheet 50 may be connected to the camera decorative piece 20 by bonding. The shape of the decorative sheet 50 may be circular, rectangular, diamond or other irregular shapes, and the embodiments of the present application do not impose strict restrictions on the thickness, shape, etc. of the decorative piece.

[0121] In a possible implementation, Fig.13a and Fig.13b As shown, the electronic device 200 may further include a fixing layer 260 and a protective layer 270, the protective layer 270 and the fixing layer 260 are sequentially stacked on the bottom wall of the receiving groove 213, the decorative sheet 50 covers the fixing layer 260, and the fixing layer 260 bonds the camera decorative part 20 and the decorative sheet 50. Among them, the fixing layer 260 can play a fixing role so that the camera decorative part 20 and the decorative sheet 50 are fixed. The protective layer 270 can not only seal the camera module 230 and prevent water vapor, impurities, etc. from the external environment from entering the interior of the electronic device 200, but also play a role in buffering the decorative sheet 50. Exemplarily, the fixing layer 260 can be a double-sided adhesive.

[0122] The fixing layer 260 is provided with a first avoidance hole 2610, and the protective layer 270 is provided with a second avoidance hole 2710, the second avoidance hole 2710 is arranged corresponding to the first avoidance hole 2610, and the first avoidance hole 2610 is connected to the second avoidance hole 2710, so that the light outside the electronic device 200 can enter the camera module 230. In other words, the fixing layer 260 and the protective layer 270 can both be hollow ring-shaped.

[0123] The embodiments of the present application are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core idea of ​​the present application. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
