Detailed Description

As used herein, an "electronic device" (or simply "terminal") includes, but is not limited to, an apparatus that is configured to receive/transmit communication signals via a wireline connection, such as via a Public Switched Telephone Network (PSTN), a Digital Subscriber Line (DSL), a digital cable, a direct cable connection, and/or another data connection/network, and/or via a wireless interface (e.g., for a cellular network, a Wireless Local Area Network (WLAN), a digital television network such as a DVB-H network, a satellite network, an AM-FM broadcast transmitter, and/or another communication terminal). A communication terminal arranged to communicate over a wireless interface may be referred to as a "wireless communication terminal", "wireless terminal" or "mobile terminal". Examples of mobile terminals include, but are not limited to, satellite or cellular telephones; a Personal Communications System (PCS) terminal that may combine a cellular radiotelephone with data processing, facsimile and data communications capabilities; PDAs that may include radiotelephones, pagers, internet/intranet access, Web browsers, notepads, calendars, and/or Global Positioning System (GPS) receivers; and conventional laptop and/or palmtop receivers or other electronic devices that include a radiotelephone transceiver. A cellular phone is an electronic device equipped with a cellular communication module.

The inventor finds that in order to enable the internal and external air pressure of the mobile phone to be balanced and have the waterproof and dustproof effects, the vent holes of the mobile phone are arranged on the lens decorating part, and meanwhile, the waterproof and breathable film is attached to the vent holes of the lens decorating part, so that the inside and the outside of the mobile phone are breathable and waterproof. The assembly process of the technical scheme generally comprises the steps of firstly assembling the lens decoration part on a rear cover of the mobile phone, then carrying out air tightness test on the rear cover with the lens decoration part, attaching a waterproof breathable film to the air holes of the lens decoration part after the test is passed, and finally carrying out complete machine assembly. In the assembling process, the bonding of the waterproof breathable film is a separate process, so that the bonding is not closely related to the processes before and after the assembling process. Therefore, in the assembly process, the waterproof breathable film is easily attached in a leakage manner, and whether the waterproof breathable film is attached in a leakage manner or not can be detected by means of no reliable detection measures in subsequent processes, so that poor products which cannot meet the requirements of water resistance and dust resistance flow out, quality accidents are caused, and the product yield of mobile phone assembly is reduced. In addition, if the waterproof breathable film is attached firstly, then the air tightness test is carried out, the air tightness test precision is influenced, and the probability of error test is increased. The reason is that, in the air tightness test process, the air holes on the lens decorating part need to be blocked so as to detect whether the sealing structure of the rear cover and the lens decorating part meets the standard or not. If the waterproof breathable film is attached firstly, when the air holes in the lens decorating part are plugged, the plug of the testing equipment needs to cover the waterproof breathable film to plug the air holes. The surface roughness of the waterproof breathable film is large, a gap is easily formed between the plug of the testing equipment and the waterproof breathable film, so that the sealing is not tight, air leakage can occur in the air tightness testing process, misdetection is caused, and the production efficiency of the mobile phone is influenced. Therefore, the waterproof breathable film needs to be attached to the breathable hole of the lens decorating part after the airtightness test.

In order to solve the technical problem, embodiments of the present application provide an electronic device, a lens decoration, a rear case assembly and an assembling method thereof. The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Further, the display screen 110 may include a transparent cover 111, a display panel 112, and a touch panel 113 stacked together. The touch panel 113 is disposed between the transparent cover 111 and the display panel 112. The transparent cover 111 mainly protects the display panel 112 and may serve as an outer surface of the electronic device 10. Meanwhile, the surface of the transparent cover plate 111 has a smooth characteristic, so that a user can perform touch operations such as clicking, sliding and pressing. The transparent cover 111 may be made of a rigid material such as glass, or may be made of a flexible material such as Polyimide (PI) or Colorless Polyimide (CPI). The display panel 112 is mainly used for displaying a screen, and can be used as an interactive interface to instruct a user to perform the touch operation on the transparent cover 111. The touch panel 113 is mainly used for responding to a touch operation of a user, and converting the corresponding touch operation into an electrical signal to be transmitted to the processor of the electronic device 10, so that the electronic device 10 can respond to the touch operation of the user. In this embodiment, the transparent cover 111, the display panel 112 and the touch panel 113 may be attached together by using an optical Adhesive (OCA) or a Pressure Sensitive Adhesive (PSA). In addition, in some embodiments, the outer surface of the electronic device 10 (i.e., the outer surface of the transparent cover plate) may be further provided with any one of other functional film layers, such as a tempered film, a frosted film, a decoration film, a peep-proof film, a water condensation film, and the like, so that the electronic device 10 can provide different use effects for users. The terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

In the present embodiment, the Display screen 110 may be a screen using an OLED (Organic Light-Emitting Diode) for image Display, or a screen using an LCD (Liquid Crystal Display) for image Display. The display screen 110 may be a flat screen, a hyperboloid screen, or a four-curved screen, which is not limited in this embodiment. It should be noted that the flat panel screen refers to the display screen 110 which is integrally arranged in a flat panel shape; the hyperboloid screen is that the left and right edge regions of the display screen 110 are arranged in a curved shape, and other regions are still arranged in a flat shape, so that the black edge of the display screen 110 can be reduced, the visible region of the display screen 110 can be increased, and the aesthetic appearance and the holding hand feeling of the electronic device 10 can be increased; the four-curved-surface screen is that the upper, lower, left and right edge regions of the display screen 110 are all in a curved arrangement, and other regions are still in a flat arrangement, so that the black edge of the display screen 110 can be further reduced, the visible region of the display screen 110 can be increased, and the aesthetic appearance and the holding hand feeling of the electronic device 10 can be further increased.

Further, as shown in fig. 2, the middle frame 120 may include a middle plate 121 and a side frame 122 that are integrally formed, and the middle plate and the side frame may be integrally formed through injection molding, punch forming, heat absorption forming, or the like. The frame 122 may be formed by extending a sidewall of the middle plate 121 in a thickness direction of the middle plate 121, so that the frame 122 and the middle plate 121 may form a corresponding open structure. The open structure can cooperate with the rear housing assembly 200 to form the receiving space 101. In this embodiment, the camera 300 may be disposed on a surface of the middle plate 121 close to the rear housing assembly 200, so as to be fixed in the accommodating space 101. The accommodating space 101 may be used to accommodate the camera 300, and may also be used to accommodate functional devices such as a battery, a motherboard, and a speaker, so as to implement various functional applications of the electronic device 10. In addition, in some embodiments, the middle plate 121 and the frame 122 may also be two independent structural members, and the two may be connected by one of assembling methods such as clamping, bonding, welding, and the like, and a combination thereof.

Referring to fig. 3 to 4, fig. 3 is an exploded view of the rear housing assembly 200 in fig. 2, and fig. 4 is a partial view of the rear cover 210 in fig. 3.

As shown in fig. 3, the rear case assembly 200 may include a rear cover 210, a functional element 220, a lens decoration 230, and a lens 240. The functional element 220 and the lens decoration 230 are disposed on the rear cover 210, and the lens 240 is disposed on the lens decoration 230. The camera 300 may be disposed opposite to the lens decoration 230, and the external light may irradiate to the camera 300 through the lens 240 and the lens decoration 230, so as to implement a shooting function of the camera 300. In this embodiment, in the assembly process of the rear housing assembly 200, the yield of the product assembled by the rear housing assembly 200 can be effectively improved, and the probability of causing quality accidents is reduced.

Specifically, as shown in fig. 4, the rear cover 210 may be configured to protect the functional devices disposed in the accommodating space 101, and may cover a side of the frame 122 away from the middle plate 121, that is, the open structure formed by the middle plate 121 and the frame 122, so as to form the accommodating space 101 together with the middle frame 120. In the present embodiment, the rear cover 210 may be used to mount the functional member 220 and the lens decoration 230. For example, the rear cover 210 may be opened with a mounting groove 211 for mounting the lens decoration 230, and the mounting groove 211 may penetrate the rear cover 210 in a thickness direction of the rear cover 210. The lens decoration 230 may be disposed on a surface of the rear cover 210 adjacent to the middle frame 120 and cover the mounting groove 211. The lens decoration 230 and the rear cover 210 may be connected by a back adhesive to improve the sealing performance. So that the external light can be irradiated to the lens decoration 230 through the mounting groove 211. Correspondingly, the rear cover 210 may further have a mounting hole 212 for mounting the functional element 220, and the mounting hole 212 may be disposed adjacent to the mounting groove 211. The functional element 220 may be disposed on a surface of the rear cover 210 adjacent to the middle frame 120 and cover the mounting hole 212. The functional element 220 and the rear cover 210 may also be connected by a back adhesive to improve the sealing performance. The functional element 220 can thus be used for its function via the mounting hole 212. In addition, in some embodiments, the rear cover 210 may be not limited to the mounting function element 220 and the lens decoration 230, but may also be mounted with other components actually required, and the embodiment is not limited thereto.

In this embodiment, the material of the middle frame 120 and the rear cover 210 may be glass, metal, hard plastic, etc., so that the middle frame 120 and the rear cover 210 have certain structural strength. Meanwhile, since the middle frame 120 and the rear cover 210 are generally directly exposed to the external environment, the middle frame 120 and the rear cover 210 may have certain wear-resistant, corrosion-resistant, scratch-resistant, and other properties, or the outer surfaces of the middle frame 120 and the rear cover 210 (i.e., the outer surfaces of the electronic device 10) may be coated with a layer of functional material for wear-resistant, corrosion-resistant, scratch-resistant. Furthermore, in some embodiments, the middle frame 120 and the rear cover 210 may be designed with the same color to enhance the appearance of the electronic device 10. In other embodiments, the middle frame 120 and the rear cover 210 may be designed with different colors to show different appearance effects. Meanwhile, a corresponding brand identifier (LOGO) may be further disposed on the middle frame 120 and the rear cover 210 to beautify the appearance of the electronic device 10 and improve the brand recognition degree.

Further, in the present embodiment, the functional element 220 may be a flash, and the light emitting surface thereof may be disposed opposite to the mounting hole 212. When the functional element 220 is operated, the light emitted by the functional element can be emitted to the outside of the electronic device 10 through the mounting hole 212, so as to realize the light emitting function. In some embodiments, the function 220 may also be an ambience lamp to provide different lighting colors and lamp effects. Further, the function 220 may also be a sensor, such as an infrared sensor. When the functional element 220 works, the infrared light emitted by the functional element can be irradiated to the outside of the electronic device 10 through the mounting hole 212, so as to realize the functions of measuring temperature, measuring distance and the like.

Referring to fig. 5 to 11, fig. 5 is a schematic structural view of the lens garnish 230 of fig. 3, fig. 6 is a schematic exploded structural view of the lens garnish 230 of fig. 5, fig. 7 is a schematic sectional view of the lens garnish 230 of fig. 5 taken along xi-xi, fig. 8 is a schematic structural view of the first housing 231 of fig. 6, fig. 9 is a schematic structural view of the waterproof breathable membrane 232 of fig. 6, fig. 10 is a schematic sectional view of the waterproof breathable membrane 232 of fig. 9 taken along v-v, and fig. 11 is a schematic structural view of the second housing 233 of fig. 6.

As shown in fig. 5 and 6, the lens decoration 230 may include: a first shell 231, a waterproof and breathable film 232 and a second shell 233. The first case 231, the waterproof breathable film 232, and the second case 233 are stacked in this order. The opposite regions of the first casing 231 and the second casing 233 are both provided with holes for balancing the air pressure inside and outside the electronic device 10. The waterproof breathable film 232 is disposed between the first housing 231 and the second housing 233 to separate the holes of the first housing 231 and the second housing 233, so that the lens decoration 230 can meet the waterproof performance required by the electronic device 10 while achieving the breathable function. In this embodiment, the lens decoration 230 is disassembled into the first housing 231 and the second housing 233, so that the waterproof breathable film 232 can be used as a part of the lens decoration 230 to participate in the assembly of the lens decoration 230, thereby effectively reducing the probability that the waterproof breathable film 232 is missed, improving the product yield of the electronic device 10 assembly, and avoiding causing quality accidents. The terms "first", "second" and "third" in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any indication of the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

Specifically, as shown in fig. 7 and 8, the first housing 231 may be used to be coupled with the rear cover 210 so that the lens decoration 230 may be fixed on the rear cover 210. For example, the first housing 231 may be disposed on a surface of the rear cover 210 close to the middle frame 120 and cover the mounting groove 211. Wherein, a back adhesive may be disposed between the contact areas of the first housing 231 and the rear cover 210 to improve the sealing performance of the first housing 231 and the rear cover 210. In this embodiment, a region of the first housing 231 opposite to the mounting groove 211 may extend in a direction away from the middle frame 120 through the mounting groove 211, so that a partial region of the first housing 231 may penetrate through the rear cover 210, thereby forming the escape space 2310. The avoiding space 2310 can be used for accommodating the camera 300 and avoiding interference between the camera 300 and the lens decoration 230.

As shown in fig. 8, in order to realize the ventilation function of the lens decoration 230, the first housing 231 may be provided with first ventilation holes 2311. The first air hole 2311 may be formed in an area where the first casing 231 and the rear cover 210 are stacked, so as to prevent the first air hole 2311 from being directly exposed on a surface of the rear cover 210 departing from the middle frame 120, which affects the appearance refinement of the electronic device 10. Meanwhile, the first air hole 2311 may penetrate the first case 231 in the thickness direction of the first case 231, so that the external air may enter the waterproof air-permeable film 232 through the first air hole 2311. In this embodiment, the orthographic projection of the first housing 231 on the waterproof breathable film 232 can be overlapped with the waterproof breathable film 232, so that the waterproof breathable film 232 can be completely attached to the first housing 231, and the waterproof breathable film 232 is prevented from being attached to a bias, which affects the waterproof performance of the lens decoration 230. In addition, the lens decoration 230 may further have a hole in a region corresponding to the optical axis direction of the camera 300, so as to implement the shooting function of the camera 300. For example, the first housing 231 may further have a first light hole 2312. The first light transmission hole 2312 may be opened in a region of the first housing 231 opposite to the mounting groove 211, that is, an orthographic projection of the first light transmission hole 2312 on the rear cover 211 may be located in the mounting groove 211. Therefore, the external light can be irradiated to the camera 300 through the first light transmission hole 2312, so that the shooting function of the camera 300 is realized. In this embodiment, the first housing 231 may also be provided with a plurality of first light holes 2312, for example, two, three, four or more, and the specific number thereof may be specifically set according to the number of the cameras 300. Meanwhile, the arrangement of the first light holes 2312 may be varied, such as a circular arrangement, a vertical arrangement, a horizontal arrangement, and the like, and the specific arrangement may be adjusted according to the arrangement of the camera 300. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

Further, as shown in fig. 7 and 9, a waterproof breathable film 232 may be disposed on a side of the first housing 231 facing away from the rear cover 210. In this embodiment, the waterproof breathable film 232 may have a waterproof and breathable function, and the thickness of the waterproof breathable film 232 may be adjusted according to the specific thickness of the lens decoration 230. When the external air enters the waterproof breathable film 232 through the first air hole 2311, the waterproof breathable film 232 can permeate the air, so that the air pressure inside and outside the electronic device 10 is kept balanced. When external liquid enters the waterproof breathable film 232 from the first air hole 2311, the liquid is blocked outside by the waterproof breathable film 232, so that the waterproof performance required by the electronic device 10 is met. In addition, in order to realize the light transmission function of the lens decoration 230, the waterproof breathable film 232 may be provided with a notch 2320 in a region corresponding to the first light transmission hole 2312, so that the light incident from the first light transmission hole 2312 can be irradiated to the camera 300 through the notch 2320. In this embodiment, the gap 2320 may be adapted to the size of the first light transmissive hole 2312, so as to prevent light from irradiating other areas in the accommodating space 101 through the gap 2320. Meanwhile, the number of the notches 2320 may correspond to the number of the first light transmission holes 2312, and each first light transmission hole 2312 only needs to correspond to one notch 2320 independently.

As shown in fig. 10, in the present embodiment, the waterproof and breathable film 232 may include a first adhesive layer 2321, a waterproof and breathable layer 2322, and a second adhesive layer 2323, which are sequentially stacked. The notch 2320 may penetrate through the first adhesive layer 2321, the waterproof breathable layer 2322 and the second adhesive layer 2323. The first and second

adhesive layers

2321 and 2323 may be double-sided tapes having air permeability. The first adhesive layer 2321 may be used to attach the first case 231 and the waterproof breathable layer 2322, and the second adhesive layer 2323 may be used to attach the second case 233 and the waterproof breathable layer 2322. This waterproof ventilative layer 2322 can have waterproof ventilative function, and its specific realization principle is, under the steam state, water particle is very tiny, according to the principle of capillary motion, can permeate the capillary to the opposite side smoothly to take place the ventilative phenomenon. When water vapor is condensed into water drops, the particles become bigger, and water molecules cannot smoothly separate from the water drops and permeate to the other side under the action of the surface tension of the water drops (mutual 'pull-up and counter-balance' among the water molecules), so that the water permeation is prevented, and the vapor permeable membrane has a waterproof function. Thus, the first adhesive layer 2321 and the second adhesive layer 2323 are bonded to the two opposite surfaces of the waterproof and breathable layer 2322, so that the waterproof and breathable film 232 can have adhesive capacity. In the assembly process of the lens garnish 230, the first housing 231 and the second housing 233 can be adhesively fixed only by the waterproof breathable film 232, thereby further reducing the sticking missing probability of the waterproof breathable film 232 in the assembly process of the lens garnish 230.

Further, as shown in fig. 7 and 11, the second casing 233 may be disposed on a side of the waterproof and breathable film 232 facing away from the first casing 231. The second casing 233 may be formed with a second vent 2331 opposite to the first vent 2311. The waterproof vent film 232 may be spaced apart from the first vent 2311 and the second vent 2331, so that the external air may enter the inside of the electronic device 10 through the first vent 2311, the waterproof vent film 232 and the second vent 2331, thereby maintaining the air pressure inside and outside the electronic device 10 to be balanced. Accordingly, when external liquid enters the waterproof breathable film 232 through the first vent 2311, the waterproof breathable film 232 isolates the liquid from the second vent 2331, thereby satisfying the waterproof performance of the electronic device 10. In this embodiment, the orthographic projection of the second housing 233 on the waterproof breathable film 232 can be overlapped with the waterproof breathable film 232, so that the waterproof breathable film 232 can be completely attached to the second housing 233, and the waterproof breathable film 232 is prevented from being attached to a bias, which affects the waterproof performance of the lens decoration 230. In addition, in order to realize the light transmitting function of the lens decoration 230, the second housing 233 may be opened with a second light transmitting hole 2332 in a region corresponding to the notch 2320, so that light incident from the first light transmitting hole 2323 can be irradiated to the camera 300 through the notch 2320 and the second light transmitting hole 2332, thereby realizing the photographing function of the camera 300. In this embodiment, the second light-transmitting hole 2332 can be matched with the size of the gap 2320 to prevent light from irradiating other regions in the accommodating space 101 through the second light-transmitting hole 2332. Meanwhile, the number of the second light holes 2332 may correspond to the number of the first light holes 2312, and each first light hole 2312 only needs to correspond to one second light hole 2332.

Further, the lens 240 may be used to protect the camera 300 disposed in the accommodating space 101, while achieving sealing of the lens decoration 230. For example, the lens 240 may be disposed on a side of the first housing 231 facing away from the waterproof, breathable film 232, and the lens 240 may cover the first light-transmitting hole 2312. A back adhesive may be disposed between the contact area of the lens 240 and the first housing 231 to improve the sealing property between the lens 240 and the first housing 231. In this embodiment, the lens 240 may be a transparent material with one or more curved surfaces made of an optical material such as glass or resin, so as to facilitate the transmission of light.

The lens decoration 230 provided by the embodiment of the application is sequentially stacked with the first housing 231, the waterproof breathable film 232 and the second housing 233, so that the waterproof breathable film 232 can be used as a part of the lens decoration 230 to participate in the assembly of the lens decoration 230, and the integrated design with the lens decoration 230 is realized. Thus, in the subsequent assembly process of the electronic device 10, the lens decoration 230 with the waterproof and breathable film 232 can be directly assembled to the rear cover 210 of the electronic device 10, and then the rear cover 210 of the electronic device 10 is subjected to the air tightness test. Through the mode, the probability that the waterproof breathable film 232 is missed can be effectively reduced, and the product yield of the electronic equipment 10 assembly is improved.

Next, an assembling method of a rear case assembly that can be used for assembling the rear case assembly 200 of the electronic device 10 in the above-described embodiment will be described. Referring to fig. 12 to 13, fig. 12 is a step diagram of an assembling method of a rear case assembly according to an embodiment of the present application, and fig. 13 is a step diagram of an air tightness test of a rear cover assembled with a lens garnish in fig. 12.

As shown in fig. 12, an assembly method of the rear housing assembly 200 according to an embodiment of the present application includes the following steps:

s20, assembling the lens decoration to the rear cover.

Specifically, the lens decoration 230 may be adhered to the rear cover 210 to achieve assembly of the lens decoration 230 with the rear cover 210. As shown in fig. 4, the rear cover 210 may be opened with an installation groove 211 for installing the lens decoration 230. The lens decoration 230 may be covered on the mounting groove 211 from a side of the rear cover 210 close to the middle frame 120, and a partial region of the lens decoration 230 may extend away from the middle frame 120 through the mounting groove 211. The back cover 210 may be coated with a back adhesive around the mounting groove 211, or the lens decoration 230 is coated with a back adhesive in an area stacked with the back cover 210, so that when the lens decoration 230 is covered on the mounting groove 211, the lens decoration 230 can be fixedly connected with the back cover 210 through the back adhesive, thereby completing the assembly of the lens decoration 230 and the back cover 210.

Further, as shown in fig. 6, the lens decoration 230 may include a first case 231, a waterproof breathable film 232, and a second case 233 that are sequentially stacked; the first casing 231 is provided with a first air hole 2311, the second casing 233 is provided with a second air hole 2331, and the first air hole 2311 and the second air hole 2331 are oppositely arranged; the waterproof air-permeable film 232 is disposed between the first case 231 and the second case 233 to separate the first air-permeable hole 2311 and the second air-permeable hole 2331. Therefore, before the lens decoration 230 is assembled to the rear cover 210, the lens decoration 230 is also assembled. In this embodiment, the first housing 231, the waterproof breathable film 232, and the second housing 233 can be attached by glue. As shown in fig. 10, the waterproof and breathable film 232 may include a first adhesive layer 2321, a waterproof and breathable layer 2322, and a second adhesive layer 2323, which are sequentially stacked. The first adhesive layer 2321 and the second adhesive layer 2323 may be a double-sided adhesive tape having air permeability. The first case 231 can thereby be attached to one face of the waterproof breathable film 232, and the second case 233 can be attached to the other, opposite face of the waterproof breathable film 232, thereby completing the assembly of the lens garnish 230. In addition, in some embodiments, the waterproof and breathable film 232 may also only include the waterproof and breathable layer 2322, which may be configured to attach a double-sided tape to the surface of the first case 231 opposite to the second case 233, so as to assemble the first case 231, the waterproof and breathable film 232, and the second case 233.

Further, before the step of assembling the lens decoration to the rear cover, a functional member may be further assembled on the rear cover to realize a function required by the electronic apparatus 10. As shown in fig. 4, the rear cover 210 may be opened with a mounting hole 212 for mounting the functional member 220. The functional element 220 may be covered on the mounting hole 212 from a side of the rear cover 210 adjacent to the middle frame 120. The back cover 210 may be coated with a back adhesive around the mounting hole 212, so that when the functional element 220 is covered on the mounting hole 212, the functional element can be fixedly connected to the back cover 210 through the back adhesive, thereby completing the assembly of the functional element 230 and the back cover 210. In this embodiment, the functional element 220 may be a flash, and the light emitting surface thereof may be disposed opposite to the mounting hole 212. When the functional element 220 is operated, the light emitted by the functional element can be emitted to the outside of the electronic device 10 through the mounting hole 212, so as to realize the light emitting function. In some embodiments, the function 220 may also be an ambience lamp to provide different lighting colors and lamp effects. Further, the function 220 may also be a sensor, such as an infrared sensor. When the functional element 220 works, the infrared light emitted by the functional element can be irradiated to the outside of the electronic device 10 through the mounting hole 212, so as to realize the functions of measuring temperature, measuring distance and the like.

Further, after the step of assembling the lens decoration to the rear cover, a lens may be further assembled on the lens decoration to seal the lens decoration. As shown in fig. 5, the first casing 231 further has a first light hole 2312, the second casing 233 further has a second light hole 2332, and the first light hole 2312 and the second light hole 2332 are disposed opposite to each other; the waterproof breathable film 232 is provided with a gap 2320 to communicate the first light-transmitting hole 2312 and the second light-transmitting hole 2332. Therefore, the external light can enter the camera 300 through the first light hole 2312, the notch 2320 and the second light hole 2332, and the shooting function of the camera 300 is realized. In order to seal the lens decoration 230 and protect the camera 300, the lens 240 may be disposed on a side of the first housing 231 facing away from the waterproof and breathable film 232, and the first light-transmitting hole 2312 may be covered by the lens 240. The first housing 231 may be coated with a back adhesive at an area contacting with the lens 240, so that when the lens 240 is covered on the first light-transmitting hole 2312, the first housing 231 can be hermetically connected with the back adhesive, thereby completing the assembly of the lens 240 and the lens decoration 230. In this embodiment, the lens 240 may be a transparent material with one or more curved surfaces made of an optical material such as glass or resin, so as to facilitate the transmission of light.

S40, a hermetic seal test is performed on the rear cover equipped with the lens garnish.

Specifically, since the rear cover 210 and the lens decoration 230 are connected by adhesive sealing, before the whole device is assembled, the rear cover with the lens decoration 230 mounted thereon needs to be tested for air tightness to detect whether the sealing between the rear cover 210 and the lens decoration 230 meets the sealing standard required by the electronic device 10. Meanwhile, when the rear cover 210 is tested for airtightness, the rear cover 210 may be equipped with not only the lens ornament 230 but also the functional element 220 and the lens 240 as described in the above embodiments. Thus, the sealing performance of the rear cover 210 and the functional element 220, and the sealing performance of the lens decoration 230 and the lens 240 can be tested. In some embodiments, the rear cover 210 may be further assembled with other components according to actual requirements before performing the air tightness test, which is not limited by the embodiment.

As shown in fig. 13, in the present embodiment, the step of performing the airtightness test on the rear cover equipped with the lens garnish may include the steps of:

s41, placing the rear cover with the lens decoration piece in the mold.

And S42, plugging the second vent hole from one side of the second shell, which is far away from the waterproof breathable film.

And S43, inflating the mold and detecting the air pressure change in the mold.

Specifically, the mold may be formed by injection molding according to the style of the rear cover 210, and when the air tightness test is required, the assembled rear case assembly 200 may be placed in the mold, and then the mold is closed to form a closed space, and then the mold is filled with the gas without impurities, and the test equipment may obtain the air tightness data of the rear case assembly 200 according to the air pressure condition inside the mold, so as to determine whether the rear case assembly 200 satisfies the waterproof performance required by the electronic device 10. In this process, since the vent holes are formed in the lens decoration 230, before the gas containing no impurities is filled into the mold, the vent holes need to be blocked by plugs of the testing equipment, so that misdetection caused by gas leakage of the lens decoration 230 in the testing process is avoided. In the present embodiment, since the first air hole 2311 is located in the area where the first case 231 and the rear cover 210 are stacked, only the second air hole 2331 can be blocked from the side of the second case 233 away from the waterproof and breathable film 232, thereby completing the air tightness test of the rear case assembly 200.

According to the electronic device 10, the lens decoration 230, the rear housing assembly 200 and the assembling method thereof provided by the embodiment of the application, the first housing 231, the waterproof breathable film 232 and the second housing 233 are sequentially stacked, so that the waterproof breathable film 232 can be used as a part of the lens decoration 230 to participate in the assembly of the lens decoration 230, and the integral design with the lens decoration 230 is realized. Thus, in the subsequent assembly process of the electronic device 10, the lens decoration 230 with the waterproof and breathable film 232 can be directly assembled to the rear cover 210 of the electronic device 10, and then the rear cover 210 of the electronic device 10 is subjected to the air tightness test. Through the mode, the probability that the waterproof breathable film 232 is missed can be effectively reduced, and the product yield of the electronic equipment 10 assembly is improved.
