Detailed Description

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.

Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic view of a disassembled structure of an embodiment of an electronic device provided in the present application.

In the present application, the electronic device 10 may be a mobile device such as a mobile phone, a tablet computer, a notebook computer, and a wearable device. In this embodiment, the electronic device 10 is taken as a mobile phone for exemplary explanation.

As shown in fig. 1, the electronic device 10 may include a display module 11, a middle frame 12, and a housing assembly 13. The display module 11 and the housing assembly 13 are respectively located on two opposite sides of the middle frame 12, and can be assembled and connected with the middle frame 12 through one or a combination of assembling modes such as gluing, clamping, welding and the like, so that a basic structure that the display module 11 and the housing assembly 13 clamp the middle frame 12 together is formed after the three are assembled. Further, a cavity with a certain volume may be formed between the display module 11 and the housing assembly 13, and the cavity may be used to set structural members such as the camera module 14, the main board 15, and the battery 16, so that the electronic device 10 can implement corresponding functions. In other words, the display module 11 is located on a side of the camera module 14 facing away from the housing assembly 13 (specifically, may be a transparent housing 131 mentioned later). The display module 11, the camera module 14 and other components can be electrically connected to the main board 15, the battery 16 and the like through a Flexible Printed Circuit (FPC), so that they can obtain the power supply of the battery 16 and can execute corresponding instructions under the control of the main board 15.

Further, the edge of the display module 11 may be bent toward the middle frame 12, so that the picture displayed on the display module 11 can extend from the front surface of the display module 11 to the side surface thereof in a form similar to a "waterfall". So set up, not only can reduce or even hide the black edge of display module assembly 11 to make electronic equipment 10 can provide bigger demonstration field of vision for the user, can also make display module assembly 11 build a visual effect around the demonstration, thereby make electronic equipment 10 bring one kind and be different from bang screen, water droplet screen, dig the visual experience of flat full-face screen such as hole screen, over-and-under type camera, sliding closure type camera for the user, and then increase electronic equipment 10's competitiveness. Accordingly, the edges of the housing assembly 13 may also be curved toward the bezel 12 to improve the grip and aesthetic appearance of the electronic device 10.

Referring to fig. 2, fig. 2 is a schematic diagram of a stacked structure of an embodiment of the housing assembly of fig. 1.

As shown in fig. 2, the housing assembly 13 may include a transparent housing 131 and an electrochromic device 132. The electrochromic device 132 may be attached to the transparent housing 131 by using a glue (not shown in fig. 2) such as an Optical Clear Adhesive (OCA) and a Pressure Sensitive Adhesive (PSA). It should be noted that: after the housing assembly 13 is assembled with the middle frame 12, the electrochromic device 132 is closer to the display module 11 than the transparent housing 131. In this case, the transparent housing 131 may be made of glass or plastic, which has a certain structural strength to protect the electronic device 10 and a certain transmittance for light to enable the color of the electrochromic device 132 to be displayed. In general, electrochromic refers to a phenomenon in which optical properties (e.g., reflectance, transmittance, absorption, etc.) of a material undergo a stable and reversible color change under the action of an applied electric field, and appears as reversible changes in color and transparency in appearance. In this regard, the electrochromic device 132 may be a device made of an electrochromic material (i.e., an electrochromic layer as referred to hereinafter) that is capable of undergoing a stable, reversible color change under the action of an applied electric field, which color change enables the appearance decoration effect of the transparent casing 131 to be changed accordingly. In other words, under the cooperation of the electrochromic device 132 and the transparent housing 131, the housing assembly 13 not only can protect the electronic device 10, but also can change the appearance characteristics of the electronic device 10, thereby improving the appearance expressive force of the electronic device 10.

However, the inventors of the present application found in long-term studies that: limited to the basic structure of the electrochromic device 132 (hereinafter, described in connection with the description, and may be a laminated structure in short), when the housing assembly 13 is fixedly connected to the middle frame 12, if the electrochromic device 132 is attached to the middle region of the transparent housing 131, and the edge region of the transparent housing 131 is attached to the middle frame 12, the electrochromic device 132 may be suspended from the side of the transparent housing 131. In other words, if the side of the electrochromic device 132 facing away from the transparent housing 131 is not limited, it will result in the electrochromic device 132 forming a cantilever-like structure with the transparent housing 131. At this time, if the electronic apparatus 10 has a limited situation such as a collision or a drop, there may be a risk that the electrochromic device 132 is peeled off from the transparent case 131, the laminated structure of the electrochromic device 132 itself is peeled off, or the like. In this regard, the housing assembly 13 may further include a functional film 133 in the present application. Wherein, a part of the functional film 133 is connected with one side of the electrochromic device 132 which is far away from the transparent shell 131, and the other part of the functional film 133 is connected with the transparent shell 131. In other words, the electrochromic device 132 is sandwiched between the functional film 133 and the transparent casing 131, so that the side of the electrochromic device 132 away from the transparent casing 131 can be limited, thereby improving the peeling problem. Further, referring to fig. 2, when the housing assembly 13 is assembled with the middle frame 12, the transparent housing 131 and/or the functional film 133 may be connected to the middle frame 12 by using a gel such as foam, so that the middle frame 12 surrounds the electrochromic device 132. At this time, the electrochromic device 132 is not sandwiched between the middle frame 12 and the transparent housing 131, so that the electrochromic device 132 can be prevented from being crushed, especially under the limit situations of collision, falling and the like. Of course, the electrochromic device 132 may also be partially sandwiched between the middle frame 12 and the transparent casing 131 to increase the size of the color-changeable region on the casing assembly 13, as the structural strength of the electrochromic device 132 allows.

Referring to fig. 3 to 5 together, fig. 3 is a schematic top view structure diagram of an embodiment of the housing assembly in fig. 2, fig. 4 is a schematic top view structure diagram of another embodiment of the housing assembly in fig. 2, and fig. 5 is a schematic expanded structure diagram of various embodiments of the functional film in fig. 4.

Generally, for an electronic device 10 such as a mobile phone, the transparent casing 131 (commonly referred to as a "battery cover" or a "rear cover") can be mostly simply regarded as a rectangle with rounded corners; accordingly, the electrochromic device 132 may also be generally rounded rectangular. Accordingly, the functional film 133 may be an adhesive tape, and opposite, adjacent, any three, or four corners of the electrochromic device 132 may be fixed to the transparent case 131, opposite, adjacent, any three, or four sides of the electrochromic device 132 may be fixed, or the electrochromic device 132 may be integrally fixed to the transparent case 131. Of course, the functional film 133 may also secure the corners and/or edges of the electrochromic device 132 to the transparent housing 131 in other ways, which are not necessarily exhaustive.

As shown in fig. 3, the functional film 133 may have a planar shape, and may fix at least two opposite sides of the electrochromic device 132 to the transparent case 131. At this time, the transparent casing 131 may have a double-curved structure (specifically, the upper and lower sides of the transparent casing 131 in fig. 3 may be curved), that is, two opposite edges of the transparent casing 131 are curved toward the middle frame 12.

As shown in fig. 4, the functional film 133 may have a planar shape, and may fix at least four sides of the electrochromic device 132 to the transparent case 131. At this time, the transparent case 131 may have a four-sided curved structure, that is, edges of the transparent case 131 are all curved toward the middle frame 12.

It should be noted that: when the transparent casing 131 has a four-sided curved structure, if the functional film 133 adopts the structure shown in fig. 3 to fix the electrochromic device 132 on the transparent casing 131, wrinkles may occur at positions of the functional film 133 corresponding to four corners of the casing assembly 13, especially when the degree of curvature of the transparent casing 131 is large, which may affect both the assembly of the casing assembly 13 and the middle frame 12 and the external performance of the casing assembly 13. In this regard, in conjunction with fig. 5, compared to the functional film 133 shown in fig. 3, a wedge-shaped avoiding structure 1331 (shown in fig. 5 (a) and corresponding splicing line in fig. 4) may be respectively provided at four corners of the functional film 133 shown in fig. 4, so as to improve the above-mentioned wrinkle problem when the functional film 133 fixes the electrochromic device 132 to the transparent housing 131. In other words, the functional film 133 shown in fig. 4 may be mainly for accommodating the transparent case 131 of the four-sided curved structure. Of course, in the transparent case 131 having the four-sided curved structure, all four corners of the functional film 133 may be cut off as shown in fig. 5 (b).

Based on the above detailed description, with reference to fig. 3 and 4, the functional film 133 is connected to the electrochromic device 132, and may form at least two strip edges 1332, and each strip edge 1332 may be connected to the transparent housing 131 to fix the electrochromic device 132 on the transparent housing 131. Here, when the functional film 133 is connected to the electrochromic device 132 and forms two stripe-shaped edges 1332, they may be opposite to or adjacent to each other.

The inventors of the present application found in long-term studies that: the electrochromic device 132, and particularly the electrochromic layer therein, is sensitive to water oxygen and is susceptible to failure. In this regard, the related art generally provides a water oxygen barrier film on the outer surface of the electrochromic device 132 to improve the reliability of the electrochromic device 132. However, when the electrochromic device 132 with its own water and oxygen barrier film is applied to the electronic device 10, the overall thickness of the electronic device 10 is inevitably increased. In this regard, the present application optimizes the structure of the functional film 133 based on the laminated structure of the housing assembly 13, so that it is possible to improve the above peeling problem and to have a certain insulating ability against water and oxygen. At this time, since the transparent casing 131 may be made of glass, plastic, etc., and has a certain isolation capability against water and oxygen, at least two opposite sides of the electrochromic device 132 can be better protected from water and oxygen, thereby improving the reliability thereof. In addition, the electronic device 10 can be more light and thin due to the elimination of the water and oxygen barrier film of the electrochromic device 132. Of course, the electrochromic device 132 may also be provided with a water and oxygen barrier film to further improve its reliability, as the overall thickness of the electronic device 10 allows.

The following description will exemplarily take the housing assembly 13 shown in fig. 3 or fig. 4 as an example, so that the side of the electrochromic device 132 facing away from the transparent housing 131 and the edge thereof are covered by the functional film 133 as much as possible to prevent the electrochromic device from being attacked by water and oxygen. The size, shape and other parameters of the functional film 133 may be consistent with those of the transparent housing 131, and the electrochromic device 132 may be consistent with the transparent housing 131 in shape and slightly smaller than the transparent housing 131 in size, so that the functional film 133 and the transparent housing 131 cooperate to sandwich the electrochromic device 132 therebetween.

Referring to fig. 6, fig. 6 is a schematic diagram of a stacked structure of an embodiment of the functional film in fig. 2.

As shown in fig. 6, the functional film 133 may include a substrate 1333 and a water oxygen barrier layer 1334. The material of the substrate 1333 may be terephthalic acid and ethylene glycol (PET), Polycarbonate (PC), Polyimide (PI), etc., and the water-oxygen barrier layer 1334 may be one or a combination of metal oxide, inorganic substance, organic substance, etc. At this time, referring to fig. 2 and fig. 6, when the functional film 133 is attached to the electrochromic device 132 and the transparent case 131 by using a glue (not shown in fig. 2) such as an optical glue or a pressure sensitive adhesive, the water and oxygen barrier layer 1334 is disposed on the side of the substrate 1333 close to the electrochromic device 132, so that the substrate 1333 protects the water and oxygen barrier layer 1334 to improve the reliability of the functional film 133. In other words, the water oxygen barrier layer 1334 is connected to the side of the electrochromic device 132 facing away from the transparent casing 131.

Generally, the electrochromic device 132 may be transparent (substantially unlike glass) in the unpowered condition; and can present corresponding colors (such as red, blue, etc. depending on the electrochromic material therein) under the condition of electrifying. Therefore, the electrochromic device 132 tends to have poor decorative effect on the appearance of the transparent casing 131 under the non-energized condition. In this regard, the structure of the functional film 133 is further optimized based on the laminated structure of the housing assembly 13, so that the peeling problem can be improved, and the functional film has a certain water and oxygen insulating ability and a certain appearance decorative effect. The arrangement is such that the housing assembly 13 also has a certain appearance expressive force by replacing the electrochromic device 132 with the functional film 133 under the situation that the appearance decoration effect of the electrochromic device 132 on the transparent housing 131 is poor. Of course, in a situation where the electrochromic device 132 takes on a corresponding color due to power-on, the functional film 133 may also cooperate with the electrochromic device 132 to enrich the appearance expressiveness of the housing assembly 13.

Illustratively, the functional film 133 may further include an optical layer 1335, which may be mainly used to change optical properties of light such as reflectivity, transmittance, and absorption. Wherein an optical layer 1335 may be provided on the other side of the substrate 1333 from the electrochromic device 132. In other words, the optical layer 1335 and the water-oxygen barrier layer 1334 are respectively disposed on the front and back sides of the substrate 1333, so that the two layers do not interfere with each other. In some implementations, the optical layer 1335 can include a texture layer 1336 and a color layer 1337. The texture layer 1336 may be formed on the substrate 1333 by nanoimprinting, UV transfer, or the like, and the color layer 1337 may be formed on the texture layer 1336 by coating, or the like. The former may be mainly to make the functional film 133 have different glossiness at different angles, and the latter may be mainly to make the functional film 133 have different colors. In other embodiments, optical layer 1335 may be primarily a textured layer 1336 that is nanoimprinted on substrate 1333, or may be primarily a colored layer 1337 that is coated on substrate 1333.

Referring to fig. 7 and 8 together, fig. 7 is a schematic diagram of a stacked structure of an embodiment of the electrochromic device in fig. 2, and fig. 8 is a schematic diagram of a top-down structure of an embodiment of the electrochromic device in fig. 7.

As shown in fig. 7, the electrochromic device 132 may include a first substrate 1321, a first conductive layer 1322, an electrochromic layer 1323, a second conductive layer 1324, and a second substrate 1325, which are sequentially stacked. The first conductive layer 1322 and the second conductive layer 1324 are electrically connected to two opposite sides of the electrochromic layer 1323, respectively. Further, the electrochromic device 132 may further include a glue frame 1326, and the glue frame 1326 may encapsulate at least a side circumferential surface of the electrochromic layer 1323 to isolate water and oxygen from corroding the electrochromic device 132.

The first base material 1321 and the second base material 1325 may be made of a flexible transparent resin material, so that the entire structure of the electrochromic device 132 is in a flexible and bendable structural form. The first substrate 1321 and the second substrate 1325 may serve to support and protect internal structures, among other things. In some embodiments, the first substrate 1321 and the second substrate 1325 may be made of Polyethylene Terephthalate (PET; commonly known as PET), Polymethyl Methacrylate (PMMA), Polycarbonate (PC), Polyimide (PI), Colorless Polyimide (CPI), cyclic olefin polymer (COC), and the like. Further material types for first substrate 1321 and second substrate 1325 are not listed and detailed here within the understanding of the person skilled in the art.

The first conductive layer 1322 and the second conductive layer 1324 are made of a transparent conductive material. The transparent conductive material may be Indium Tin Oxide (ITO), zinc aluminum oxide (AZO), tin oxide doped with Fluorine (FTO), a graphene film, or the like. The first conductive layer 1322 and the second conductive layer 1324 may be formed by Physical Vapor Deposition (PVD), which specifically includes vacuum evaporation, sputtering, ion plating (hollow cathode ion plating, hot cathode ion plating, arc ion plating, reactive ion plating, radio frequency ion plating, direct current discharge ion plating), and the like. The thicknesses of the first conductive layer 1322 and the second conductive layer 1324 may be between 100nm and 300nm, and specifically may be 100nm, 120nm, 150nm, 200nm, 280nm, 300nm, and the like.

In this embodiment, the electrochromic device 132 may be a staggered structure. Illustratively, the glue frame 1326 may include a first glue frame portion 13261 and a second glue frame portion 13262 that are integrally connected. The first plastic frame portion 13261 surrounds the first base material 1321, and an orthographic projection of the first plastic frame portion 13261 on the transparent shell 131 is overlapped with an orthographic projection of the second base material 1325 on the transparent shell 131; the second plastic frame portion 13262 surrounds the second base material 1325, and an orthographic projection of the second plastic frame portion 13262 on the transparent shell 131 is overlapped with an orthographic projection of the first base material 1321 on the transparent shell 131.

As shown in fig. 7, the electrochromic device 132 may also include a first metal trace 1327 and a second metal trace 1328. The metal trace may include but is not limited to a multi-layer trace structure such as a silver paste line, a copper plated metal, an aluminum plated metal, or a molybdenum aluminum molybdenum. Referring to fig. 8, the first metal trace 1327 may extend along an edge of the first conductive layer 1322 and be electrically connected to the first conductive layer 1322; the second metal trace 1328 may extend along an edge of the second conductive layer 1324 and be electrically connected to the second conductive layer 1324. Further, at least one of the first metal trace 1327 and the second metal trace 1328 is embedded in the rubber frame 1326, so that the metal trace embedded in the rubber frame 1326 is isolated from the electrochromic layer 1323, and the metal trace is prevented from being corroded by the electrochromic layer 1323. Illustratively, the first metal trace 1327 may be embedded in the second plastic frame portion 13262, and the second metal trace 1328 may be embedded in the first plastic frame portion 13261. In addition, the metal traces are embedded in the plastic frame 1326, which can increase the color-changing area of the electrochromic device 132.

Further, as shown in fig. 8, the first metal trace 1327 and the second metal trace 1328 may have an L-shaped structure, and may be electrically connected to the flexible circuit board 17. The configuration is such that the electrochromic device 132 can be electrically connected with the motherboard 15, the battery 16, and the like, so as to obtain the power supply of the battery 16, and can execute corresponding instructions under the control of the motherboard 15. Of course, in other embodiments, the first metal trace 1327 and the second metal trace 1328 may also be in a ring structure, and the above electrical connection may also be achieved. Further, one end of the flexible circuit board 17 near the electrochromic device 132 may be Y-shaped to be respectively bound with the first metal trace 1327 and the second metal trace 1328, that is, bound on two sides. Of course, in some other embodiments, any one of the first metal trace 1327 and the second metal trace 1328 may be first guided to the substrate on which the other one is located by a structure such as a conductive ball, for example, the second metal trace 1328 is guided to the first substrate 1321 by silk-screening or silver paste spot-coating, and the flexible circuit board 17 is bound with the first metal trace 1327 and the second metal trace 1328 (corresponding to silver paste), that is, single-sided bound.

It should be noted that: in order to make the electrochromic device 132 have a faster color change speed, the sheet resistance of the conductive layer may be set to a specific value of 40 to 150 ohms, such as 40 ohms, 50 ohms, 80 ohms, 100 ohms, 120 ohms, 550 ohms, etc.; the sheet resistance of the metal trace may be 0.05-2 ohms, specifically 0.05 ohms, 0.06 ohms, 0.1 ohms, 1.2 ohms, 1.5 ohms, 2 ohms, and the like, and is not limited herein. So configured, the electrochromic device 132 may be colored at a rate of between 10-20 seconds, faded at a rate of between 8-12 seconds, or faster.

Referring to fig. 9 and 10 together, fig. 9 is a schematic view of a stacked structure of another embodiment of the electrochromic device in fig. 2, and fig. 10 is a schematic view of a partially enlarged structure of a portion a in fig. 9.

The main differences from the above described embodiment are: in this embodiment, the electrochromic device 132 may be a one-size chip structure, as shown in fig. 9. Illustratively, the glue frame 1326 may surround the second substrate 1325, and an orthographic projection of the glue frame 1326 on the transparent shell 131 is overlapped with an orthographic projection of the first substrate 1321 on the transparent shell 131. Further, as shown in fig. 9, the first metal trace 1327 may be embedded in the glue frame 1326, and the second metal trace 1328 may be embedded in the electrochromic layer 1323. Of course, in other embodiments, the first metal trace 1327 and the second metal trace 1328 may also be located on the same side of the electrochromic layer 1323.

As shown in fig. 10, the electrochromic layer 1323 may include a sublayer structure. The electrochromic layer 1323 may include an electrochromic material layer (i.e., an EC layer) 13231, an ion storage layer 13232, and an ion conducting layer (i.e., an IC layer) 13233 interposed between the first conductive layer 1322 and the second conductive layer 1324 and stacked in this order. Since ion-conducting layer 13233 is less aggressive to the metal trace than the other layer structure of electrochromic layer 1323, second metal trace 1328 can be embedded in ion-conducting layer 13233. Further, the electrochromic device 132 may also include an insulating layer 1329. Here, the insulating layer 1329 may mainly cover the second metal trace 1328, so that the second metal trace 1328 is isolated from the electrochromic layer 1323. The material of the insulating layer 1329 may be an organic high molecular polymer, or an inorganic substance, such as silicon oxide.

The material of the electrochromic material layer 13231 may be selected from organic polymers (including polyaniline, polythiophene, etc.), inorganic materials (prussian blue, transition metal oxides such as tungsten trioxide), and small organic molecules (viologen), etc. In the embodiment of the present application, the electrochromic layer 131 is exemplified as an organic polymer, and may specifically be a solid or gel material. Alternatively, ion conducting layer 13233 and ion storage layer 13232 may be formed by PVD, and electrochromic material layer 13231 (i.e., the organic polymer or inorganic material described above) may be formed by knife coating or drip irrigation, etc., which will not be described in detail herein to the extent that those skilled in the art will understand the detailed technical features. In addition, the electrochromic material layer 13231 may also be formed by using small organic molecules as an electrolyte material, and may be formed by a vacuum filling process between the first conductive layer 1322 and the second conductive layer 1324, which is not described in detail herein.

Based on the above detailed description, with reference to fig. 2, 7 and 9, for the electrochromic device 132, the color-changing region is mainly concentrated on the region where the electrochromic layer 1323 is located. In other words, when the electrochromic device 132 is attached to the transparent housing 131, the edge region of the housing assembly 13 except for the region corresponding to the electrochromic layer 1323 is not discolored. The edge region mainly includes a region corresponding to the glue frame 1326 (as shown in fig. 7 or 9) and an edge of the functional film 133 (as shown in fig. 2). In this regard, the edge of the housing assembly 13 may also be provided with a shielding structure 134. The shielding structure 134 can at least be used for shielding the adhesive frame 1326 to improve the consistency of the housing assembly 13 in appearance. As an example, in conjunction with fig. 2, the shielding structure 134 may be one or a combination of an ink layer, a matte layer, a graded layer, a yellow light processing layer, an imprinting layer, etc. disposed on a side of the transparent housing 131 close to the electrochromic device 132 to shield an edge region of the housing assembly 13. The color of the shielding structure 134 may be the same as or similar to the color of the electrochromic device 132 in the color rendering state, so as to achieve the visual effect that the shielding structure 134 and the electrochromic device 132 are integrated in the color rendering state.

It should be noted that: the shielding structure 134 can also be disposed in the area corresponding to the decoration 135, so that the decoration 135 is matched with the shielding structure 134, and the shielding effect on the glue frame 1326 is further improved.

With reference to fig. 1, since the camera module 14 is often disposed in the electronic device 10, the camera module 14 needs to collect light through the housing assembly 13. To this end, the housing assembly 13 (which may be specifically the transparent housing 131) may have a first region 1311 and a second region 1312, and the second region 1312 may at least partially surround the first region 1311. The first area 1311 may enable light to pass through the transparent housing 131, so that the camera module 14 collects light through the first area 1311; and the electrochromic device 132 may be primarily attached to the second region 1312. Further, the first region 1311 may have a regular shape such as a rounded rectangle, a circle, a diamond, or other irregular shapes. In other words, the specific shape and size of the first region 1311 may be adaptively adjusted according to the structure of the camera module 14 and the lighting requirement thereof, and are not limited herein.

It should be noted that: for the housing assembly 13 shown in fig. 3 or fig. 4, the portion of the functional film 133 corresponding to the first region 1311 may be provided with an avoiding hole to avoid the functional film 133 from being affected when the camera module 14 collects light, especially in the case where the functional film 133 is provided with the optical layer 1335. Further, the electrochromic device 132 may at least partially surround the camera module 14 to increase the compactness of the electronic device 10 in structure. In other words, under the condition that the transparent housing 131 meets the lighting requirement of the camera module 14, the electrochromic device 132 may cover the transparent housing 131 as full as possible to increase the size of the color-changeable area on the housing assembly 13. In this case, the camera module 14 may also partially extend into the electrochromic device 132, or even partially extend into the transparent housing 131, so as to increase the structural compactness of the electronic device 10, that is, reduce the overall thickness of the electronic device 10.

The following description is given by way of example of the relative positional relationship between the housing assembly 13 and the camera module 14:

referring to fig. 11 and 12 together, fig. 11 is a schematic top view illustrating a relative position relationship between the housing assembly and the camera module in fig. 1, and fig. 12 is a schematic cross-sectional view of the housing assembly in fig. 11 along the direction XII-XII.

As shown in fig. 11 and 12, the electrochromic device 132 may partially surround the camera module 14. Based on the above description, it is specifically possible that the rubber frame 1323 partially surrounds the camera module 14. Exemplarily, in combination with fig. 1 and 11, the number of the first regions 1311 may be one. Wherein the first region 1311 may be located at a corner of the transparent housing 131 (e.g., an upper left corner region of the electronic device 10). Referring to fig. 21, the first region 1311 may also be located at another corner of the transparent casing 131 (e.g., an upper right corner region of the electronic device 10, i.e., a region opposite to fig. 11). Referring to fig. 22, the first region 1311 may also be located in the middle region of the transparent casing 131 and adjacent to one side thereof, that is, may be between the region shown in fig. 21 and the region shown in fig. 11. It should be noted that: the first region 1311 may also be located in other regions on the transparent housing 131, which is not necessarily exhaustive here. Of course, in other embodiments, the number of the first regions 1311 may be multiple, for example, two. Wherein the two first regions 1311 may also be located at a corner of the transparent housing 131 (e.g., the upper left corner of the electronic device 10). At this time, the larger of the two first regions 1311 may be used to satisfy the usage requirement of the camera in the camera module 14, and the smaller may be used to satisfy the usage requirement of the flash in the camera module 14 or the usage requirements of various light sensors of the electronic device 10.

As shown in fig. 11 and 12, the housing assembly 13 may further include a decoration 135, and the decoration 135 may be mainly disposed in the first region 1311. Wherein the decoration 135 may be at least partially located at the other side of the transparent housing 131 facing away from the electrochromic device 132. Similarly, in conjunction with fig. 11, 21, and 22, trim piece 135 may be located at a corner of transparent housing 131 (e.g., an upper left corner region or an upper right corner region of electronic device 10); or may be located in the middle region of the transparent casing 131 adjacent to one side thereof, i.e., may be between the region shown in fig. 21 and the region shown in fig. 11.

As shown in fig. 12, the first region 1311 may be provided with a mounting hole 1313. Wherein the decoration 135 may be partially installed in the installation hole 1313. At this time, the camera module 14 can collect light through the decoration 135.

As an example, the decoration member 135 may include a connection portion 1351, a decoration portion 1352, and a light-transmissive portion 1353. Wherein, the connecting portion 1351 and the decoration portion 1352 may be integrally connected. At this time, the connection portion 1351 may be installed in the installation hole 1313; the decoration portion 1352 is located on the other side of the transparent housing 131 away from the electrochromic device 132, that is, the decoration part 135 is partially exposed out of the transparent housing 131, so as to achieve the decoration effect. Wherein the end of the decorative portion 1352 facing away from the connecting portion 1351 is provided with a chamfer, which may be a highlight chamfer. Further, the transparent portion 1353 may be made of glass or plastic, and may be disposed in the decoration portion 1352, so that the camera module 14 can collect light.

It should be noted that: the decorative portion 1352 may be closely attached to the transparent case 131, and the connecting portion 1351 may be flush with a surface of the transparent case 131 near the electrochromic device 132 to improve the reliability of the decoration 135 mounted in the mounting hole 1313.

Of course, in other embodiments, the decoration 135 may be attached to the other side of the transparent casing 131 facing away from the electrochromic device 132. At this time, the decoration member 135 may be made of metal, sapphire, or the like to decorate the first region 1311; and may be annular so that the camera module 14 may collect light. Of course, the decoration member 135 may be a sheet, and the middle region thereof may transmit light, and the edge region may perform a decoration effect.

Further, referring to fig. 11, 21, 22, and 12, the orthographic projection of the rubber frame 1326 on the transparent case 131 overlaps the orthographic projection of the garnish 135 on the transparent case 131. The garnish 135 (specifically, the garnish portion 1352) can block a portion where an orthogonal projection of the rubber frame 1326 on the transparent case 131 overlaps with an orthogonal projection of the garnish 135 on the transparent case 131. With such an arrangement, not only the glue frame 1326 can be prevented from appearing, but also the decoration part 135 (especially the decoration part 1352 thereof) can be closer to the electrochromic device 132 (especially the electrochromic layer 1323 thereof), so as to increase the matching degree of the decoration part 135 and the electrochromic device 132 on the appearance decoration, that is, further improve the appearance expressive force of the housing assembly 13.

Referring to fig. 13 and 14 together, fig. 13 is a schematic top view of the housing assembly and the camera module in fig. 1 in another relative position relationship, and fig. 14 is a schematic cross-sectional view of the housing assembly in fig. 13 along the XIV-XIV direction.

The main differences from the above described embodiment are: in this embodiment, as shown in fig. 13 and 14, the electrochromic device 132 may surround the camera module 14. Based on the above description, the plastic frame 1323 may surround the camera module 14. Illustratively, in conjunction with fig. 1 and 13, the number of the first regions 1311 may be one. Wherein the first region 1311 may be located in the middle of the transparent case 131 and adjacent to one side thereof. In conjunction with fig. 23, first region 1311 may be located at a corner of transparent housing 131 (e.g., an upper left corner region of electronic device 10). In conjunction with fig. 24, the first region 1311 may also be located at another corner of the transparent casing 131 (e.g., the upper right corner region of the electronic device 10, i.e., the region opposite to fig. 23). The region shown in fig. 13 may be between the region shown in fig. 23 and the region shown in fig. 24. It should be noted that: the first region 1311 may also be located in other regions on the transparent housing 131, which is not necessarily exhaustive here. Of course, in other embodiments, the number of the first regions 1311 may be multiple, for example, two. Wherein two first regions 1311 may also be located in the middle of the transparent case 131 and adjacent to one side thereof. At this time, the larger of the two first regions 1311 may be used to satisfy the usage requirements of the camera in the camera module 14, and the smaller may be used to satisfy the usage requirements of the flash in the camera module 14 or the usage requirements of various light sensors of the electronic device 10.

Further, with reference to fig. 13, 23, 24 and 14, since the electrochromic device 132 may surround the camera module 14, the electrochromic device 132 may be in a ring shape. At this time, the outer circumferential surface and the inner circumferential surface of the electrochromic device 132 need to be encapsulated by the rubber frame 1326 to prevent the corrosion of water and oxygen. In the entire structure of the electronic device 10, the inner peripheral surface is closer to the camera module 14 than the outer peripheral surface. Further, the rubber frame 1326 for sealing the inner circumferential surface may have a ring shape as shown in fig. 14; the inner circumferential surface of the rubber frame is filled with rubber. Based on the above-described related description, the orthographic projection of the glue frame 1326 for enclosing the above-described inner peripheral surface on the transparent case 131 may fall within the range of the orthographic projection of the garnish 135 on the transparent case 131. Illustratively, as shown in fig. 14, the decorative portion 1352 may completely cover a portion of the frame corresponding to the decoration member 135.

Similarly, in conjunction with fig. 13, 23, and 24, trim piece 135 may be located at a corner of transparent housing 131 (e.g., an upper left corner region or an upper right corner region of electronic device 10); or may be located in the middle region of the transparent casing 131 and adjacent to one edge thereof, i.e., may be between the region shown in fig. 23 and the region shown in fig. 24.

Referring to fig. 15, fig. 15 is a cross-sectional view of another embodiment of the housing assembly of fig. 13. It should be noted that: the transparent housing shown in fig. 15 is equally applicable to the housing assembly shown in fig. 11.

The main differences from the above embodiments are: as shown in fig. 15, the transparent case 131 may include a body portion 1314 and a protrusion portion 1315 integrally connected. The protrusion 1315 may protrude from a surface of the main body 1314 facing away from the electrochromic device 132, and the protrusion 1315 and the main body 1314 may be connected by an arc. So configured, the protrusion 1315 and the body 1314 cooperate to form a "crater" like structure to achieve a different appearance. At this time, the mounting hole 1313 may be provided at the boss 1315.

Further, the mounting hole 1313 may include a first mounting hole section 13131 and a second mounting hole section 13132 that communicate. Wherein the aperture of the first mounting hole section 13131 may be larger than the aperture of the second mounting hole section 13132. At this time, the decoration member 135 may be partially installed in the first installation hole section 13131. Illustratively, the connecting portion 1351 may be installed in the second mounting hole section 13132, and the decorative portion 1352 may be partially installed in the first mounting section 13131.

It should be noted that: for the case assembly shown in fig. 12, 14 and 15, the decoration member 135 can be simply viewed as being installed from the outside to the inside of the transparent case 131, with reference to the camera module 14. In other embodiments, the decorative member 135 may be installed from the inner side of the transparent member 131 to the outer side. In this case, the decoration member 135 may also be partially located on a surface of the transparent casing 131 facing away from the electrochromic device 132, or may be provided with a structure such as a high-light chamfer, which may also have a decoration effect.

Wherein the control circuit 151 may be coupled with the electrochromic device 132; the control circuit 151 is configured to receive a control command, which is used to control the electrochromic device 132 to change color.

Referring to fig. 17 together, fig. 17 is a block diagram illustrating a structural configuration of another embodiment of the electronic device in fig. 1, and fig. 18 is a schematic structural diagram illustrating an embodiment of the electronic device in fig. 17.

Wherein, the signal input device 18 can be coupled with the control circuit 151; the control circuit 151 is configured to receive a control command input through the signal input device 18 and control the operating state of the electrochromic device 132 according to the control command. At this time, the operation state of the electrochromic device 132 may include controlling to change the voltage or current signal state thereof for the purpose of controlling the electrochromic device 132 to change color. The signal input device 18 may be the display module 11, the operation button 181, the trigger sensor 182, etc., and the detailed structure and the signal input method are as follows.

For example, referring to fig. 18, the signal input device 18 may be the display module 11, and the control command input by the signal input device 18 may be a touch operation received by the display module 11. The touch operation may include at least one of sliding, clicking, and long pressing. Referring to fig. 19 and 20, fig. 19 is a schematic view of an operating state of the electronic device, and fig. 20 is a schematic view of another operating state of the electronic device.

Referring to fig. 18, the signal input device 18 may be an operation key 32. The control command may also be a triggering command of the operation key 32, where the operation key 32 may be a single key, or may be a multiplexing function with other function keys of the electronic device, such as a power key, a volume key, and the like, and the different control commands received by the control circuit 151 are defined according to different key triggering modes, and then the control circuit 151 may implement different signal controls on the electrochromic device 132.

Optionally, the control instruction is a use scene that requires the electronic device to change color, and may specifically include at least one of an image acquisition requirement, a flash lamp starting requirement, an automatic timing color change requirement, and other functional component requirements. Specifically, the image capturing requirement may be applied to a scene where a user has a shooting requirement, such as a scene of taking a picture, shooting a camera, performing a video call, etc., a scene where an electronic device is required to unlock, pay, encrypt, answer a call, or other confirmation requirements, etc. The flash lamp turning-on requirement can be that when a user needs to turn on the flash lamp, specifically, the control circuit 151 controls the electrochromic device 132 to change the transparent state, and the electronic device can show a color-changing appearance effect by combining structures such as an appearance membrane, a substrate color layer and the like.
