The adhesive portion 13 is provided between the barrier 122 and the electrochromic layer 112, and hermetically connects the camera decoration piece 12 and the electrochromic layer 112.
Specifically, the lens body 111 may be a transparent plate. In other words, the lens body 111 may be transparent, and light may pass through the lens body 111. The thickness of the lens body 111 can increase the strength thereof, and avoid the lens body 111 from being broken by external impact, and the thickness of the lens body 111 can be 0.2 mm to 1 mm, for example: 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or 1.0 mm. Alternatively, the thickness of the lens body 111 of the present embodiment is 0.5 mm, and the glass with the thickness of 0.5 mm does not make the whole decoration assembly thick, but also resists external impact. In addition, silk-screen printing traces are formed on one side of the lens body 111 through silk-screen printing. The lens body 111 may be a convex lens, an anti-fog lens, a brightness enhancement lens, an infrared cut filter lens, or a sapphire lens, or other lenses having unique functions. In addition, other lenses with unique functions may also be used as the lens body 111 to obtain different shooting effects, which is not described herein.
At least a part of the surface of the lens body 111 is provided with an electrochromic layer 112. It is understood that a portion of the lens body 111 may be provided with the electrochromic layer 112, for example, the window region 1121 region of the lens body 111, i.e., the region of the lens body 111 that realizes the light transmission function, is coated with the electrochromic layer 112.

For example, when the electrochromic layer 112 is in the first light-transmitting state, the electrochromic layer 112 may be in a transparent state, and at this time, the lens body 111 may transmit all light, and the camera module 30 may perform normal shooting. When the electrochromic layer 112 is in the second light-transmitting state, the electrochromic layer 112 may be in red, blue, gray, or white, and the lens body 111 may be adapted to the housing 21 of the electronic device, so as to improve the appearance performance of the electronic device.

The camera decoration 12 of the present embodiment is used to decorate the cameras, the number of the cameras may be one or more, the number of the through holes 1211 may correspond to the number of the cameras and the number of the flash lamps one to one, in the present embodiment, the number of the cameras is two, the number of the flash lamps is one, and the number of the through holes 1211 is three. The camera decoration 12 may be made of metal, such as iron or aluminum, or plastic.
In an actual production process, in order to connect the first flat plate 121 and the baffle plate 122 more firmly and reduce the cost in the processing process, in the embodiment, the first flat plate 121 and the baffle plate 122 may be integrally formed, and certainly, a person skilled in the art should not be limited to "integrally forming", the first flat plate 121 and the baffle plate 122 may be fixed in a welding manner, and the person skilled in the art may flexibly select a fixing manner of the first flat plate 121 and the baffle plate 122 according to actual requirements.
The lens module 11 can be attached to the first plate 121 in the axial direction of the through hole 1211, and the blocking plate 122 is abutted to the lens body 111 and spaced from the electrochromic layer 112. There are various ways to connect the baffle 122 and the electrochromic layer 112, and in this embodiment, the baffle 122 and the electrochromic layer 112 are bonded together by the adhesive 13. That is, the barrier 122 and the electrochromic layer 112 together enclose a space, which is located below the lens body 111 and does not cover the electrochromic layer 112, and the adhesive part 13 fills the space to hermetically connect the camera decoration 12 and the electrochromic layer 112. Therefore, when the electrochromic layer 112 is in the second light-transmitting state, the lens body 111 corresponding to the space does not show the color of the electrochromic layer 112.
The camera decoration piece 12 further includes a second plate 123, the second plate 123 is disposed on a side of the baffle 122 away from the first plate 121, and the second plate 123 abuts against the electronic device housing 21. The lens module 11 cooperates with the electronic device housing 21 to clamp the camera decoration 12, so as to increase the stability and the overall strength of the camera cover plate 10.
Unlike the case of the related art, the camera cover 10 of the present embodiment includes: lens module 11, camera decoration 12 and sticky portion 13, camera decoration 12 is including the first flat board 121 and the baffle 122 that meet, baffle 122 sets up and protrusion in first flat board 121 around first flat board 121, baffle 122 and lens body 111 butt and with electrochromic layer 112 interval setting, lens module 11 bears and leans on first flat board 121, sticky portion 13 sets up between camera decoration 12 and electrochromic layer 112, and sealing connection camera decoration 12 and electrochromic layer 112.

In one embodiment, the gap between camera trim piece 12 and electrochromic layer 112 is 0.15 to 0.35 millimeters. For example: 0.15 mm, 0.20 mm, 0.25 mm, 0.3 mm, or 0.35 mm. Alternatively, the gap between the camera decoration piece 12 and the electrochromic layer 112 of the present embodiment is 0.25 mm, that is, the glue filling space is 0.25 mm, and the glue portion 13 with a thickness of 0.25 mm may be filled.

Therein, an electrochromic functional layer 1125 is disposed between the first electrode layer 1123 and the second electrode layer 1124.

The first electrode layer 1123 and the second electrode layer 1124 may be formed of transparent conductive materials, and thus, a color generated by the electrochromic functional layer 1125 may be expressed from either side of the electrochromic layer 112. According to an embodiment of the present application, the first electrode layer 1123 and the second electrode layer 1124 may each be formed of indium tin oxide. The electrochromic functional layer 1125 may be made of at least one of an inorganic electrochromic material, an organic small molecule electrochromic material, and an organic polymer. Thus, the electrochromic layer 112 may be formed from a variety of materials as described above, such that the electrochromic layer 112 has a wide source of materials. According to this embodiment, the inorganic electrochromic material may be transition metal oxide, prussian blue, or the like, the organic small-molecule electrochromic material may be viologen, and the organic polymer may be polyaniline, polythiophene, or the like.

Specifically, the first intersection point P1 and the second intersection point P2 are used for defining an avoidance gap for avoiding the conducting wires 1126 on two sides, and when the paste is printed or sprayed to prepare the first electrode layer 1123, the electrochromic functional layer 1125 and the second electrode layer 1124, the avoidance gap is arranged to effectively prevent the paste from contacting the conducting wires 1126, so that the conducting wires 1126 can be normally connected with external circuits, and the malfunction of the operation is avoided.
Wherein the window region 1121 may have a first edge 1121A and a second edge 1121B, the first edge 1121A being close to a first intersection point P1, and the second edge 1121B being close to a second intersection point P2, wherein a gap between the first intersection point P1 and the first edge 1121A may be 0.3-0.5 mm, for example: 0.3 mm, 0.35 mm, 0.40 mm, 0.45 mm, or 0.5 mm. The gap between the second intersection point P2 and the second edge 1121B may be 0.3-0.5 mm, for example: 0.3 mm, 0.35 mm, 0.40 mm, 0.45 mm, or 0.5 mm.
Specifically, the gap between the first intersection point P1 and the first edge 1121A and the gap between the second intersection point P2 and the second edge 1121B are the avoidance gaps in the above-described embodiments.
Wherein, the distance between the outer edge of the non-window region 1122 and the edge of the window region 1121 may be 2.3-2.6 mm, for example: 2.3 mm, 2.4 mm, 2.5 mm, or 2.6 mm.

Wherein the number of the conductive lines 1126 may be configured according to the number of the divided regions of the color-changing region of the electrochromic layer 112 to enable independent control of the plurality of color-changing regions of the electrochromic layer 112, such that the electrochromic layer 112 enables independent color changing of the plurality of regions.
That is, a plurality of wires 1126 may be respectively disposed at the edges of the first electrode layer 1123 and the second electrode layer 1124, the plurality of wires 1126 are connected to the flexible circuit board 14, and the plurality of wires 1126 are configured to apply a voltage to a plurality of regions of the first electrode layer 1123 and the second electrode layer 1124, so as to form a plurality of electric fields that can change the color of the electrochromic layer 112, and the electrochromic layer 112 may be changed in a large region or a local region or a plurality of regions independently, so that the electrochromic layer 112 has a colorful appearance.
In one embodiment, the camera cover 10 further includes: a flexible circuit board 14, the flexible circuit board 14 being connected to the electrochromic layer 112. Wherein the length of the electrochromic layer 112 in the length direction is greater than or equal to the length of the electrochromic layer 112 in the width direction, and the flexible circuit board 14 extends in the length direction.
Specifically, the binding width of the flexible circuit board 14 is usually 0.4-0.6 mm (e.g., 0.4 mm, 0.5 mm, or 0.6 mm), and it is also necessary to reserve an escape gap on each side of the flexible circuit board 14 by 0.2 mm. Therefore, if the flexible circuit board 14 extends in the width direction, the width of the camera cover 10 needs to be increased by 0.8-1.2 mm (e.g., 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, or 1.2 mm).
According to the embodiment of the application, the flexible circuit board 14 has a bendable characteristic, so that the flexible circuit board 14 is wired from the electrode layer by using the conducting wire 1126 to electrically connect the flexible circuit board 14, the frame of the electrochromic layer 112 can be made narrower, and only the contact point between the flexible circuit board 14 and the conducting wire 1126 is reserved. In one aspect, the flexible circuit board 14 is more transparent than the copper sheets and, therefore, more transparent at the contact points of the flexible circuit board 14 with the conductive leads 1126, i.e., the portion of the frame viewed from the upper surface of the electrochromic layer 112. On the other hand, the flexible circuit board 14 has flexibility, and compared to the copper sheet, the flexible circuit board 14 except for its contact point with the conductive wire 1126 may be bent to the back of the electrochromic layer 112, and thus, the frame of the electrochromic layer 112 may be narrower.

That is, only one flexible circuit board 14 needs to be disposed on each electrode layer, and a plurality of independent connection points can be disposed on the flexible circuit board 14, and the connection points are respectively connected with the conducting wires 1126 of each area on the electrode layer, so that the respective control of the plurality of areas can be realized, the space is saved, and the independent color change of the plurality of areas can be realized. At present, in a mode of connecting the electrode layer through the copper sheets, if independent color change of a plurality of areas is realized, a plurality of copper sheets need to be arranged and are respectively led out from the electrode layer, as described above, a space occupied by one copper sheet is very large, and if independent color change of a plurality of areas is realized, more space is inevitably occupied, which is also not beneficial to realization of independent color change of the plurality of areas, so that the electrochromic layer 112 can only present a single color. Therefore, compared with the existing electrochromic layer 112, the electrochromic layer 112 according to the embodiment of the application has the advantages that the wiring mode is simpler, the occupied space is smaller, the frame is narrower, independent color change of a plurality of areas can be realized, and the requirement of a user on colorful appearance is met.

Referring to fig. 9, fig. 9 is a schematic flowchart of an electrochromic method according to an embodiment of the present disclosure, where the electrochromic method is applied to an electronic device in the foregoing embodiments, where the electronic device includes an electrochromic layer, a camera module, and a motherboard, and the method includes the following steps:
s10: and detecting the state of the camera module in real time, wherein the state comprises an activated state and an idle state.
S20: when the camera module is in an activated state, the mainboard controls the electrochromic layer to change the light transmittance, so that the camera module of the electronic equipment acquires a light signal passing through the electrochromic layer.
S30: when the camera module is in an idle state, the mainboard controls the electrochromic layer to reduce the light transmittance, so that the camera module of the electronic equipment is hidden.
In particular, the electrochromic layer may be switchable between a first state and a second state, wherein the first state is a non-transparent state or a translucent state and the second state is a transparent state. The camera head collects images through the electrochromic layer when the electrochromic layer is in a transparent state, wherein the transparent state includes a fully transparent state and various semi-transparent states between the fully transparent state and the non-transparent state. Specifically, the non-transparent or non-transparent state is that the user cannot perceive the camera through the rear cover with naked eyes, that is, the effect of completely hiding the camera is achieved; the semi-transparent or semi-transparent state is that a user can see the outline of the camera through the rear cover by naked eyes, so that the effect of at least partially hiding the camera is achieved; the full transparency or full transparency state allows the user to see the camera profile and specific structural details through the back cover.
Several working process states of the electronic device are described as follows, and the principle of using the electrochromic layer as the electrochromic layer is explained. (1) Firstly, starting a camera, namely in a shooting state, starting the electrochromic layer to change color, converting a shielding state, namely an opaque state, into a transparent state, finishing shooting by the camera, closing the camera, starting the electrochromic layer to change color in a reverse direction, and converting the transparent state into the shielding state; (2) the method comprises the following steps that firstly, an electrochromic layer is started to change color, a shielding state, namely an opaque state, is changed into a transparent state, when the electrochromic layer is completely changed into the transparent state, a camera is started to work and complete shooting, the camera is closed, the electrochromic layer is started to change color in a reverse direction, and the transparent state is changed into the shielding state to hide the camera. It should be noted that, in the above two working state processes, after the camera finishes shooting, the two processes of turning off the camera and turning on the electrochromic layer for reverse color change may be performed simultaneously or any one of the two processes may be performed first, and no specific limitation is made here.
Further, there are also two states of the electrochromic layer, the blocked state, which we can call the default state; and a non-blocking state, which is called an operating state, wherein the blocking state may be an energized state of the electrochromic layer, i.e. when the electrochromic layer changes from the blocking state to the non-blocking state, the energization of the electrochromic layer is stopped, or a reverse voltage is applied to the electrochromic layer, wherein the reverse voltage is applied in order to accelerate the color change speed thereof. When the electrochromic layer changes from the non-shielding state to the shielding state, the electrochromic layer may be energized. In addition, the blocking state of the electrochromic layer may also be a non-energized state, that is, when the electrochromic layer changes from the blocking state to the non-blocking state, the electrochromic layer may be energized, and when the electrochromic layer changes from the non-blocking state to the blocking state, the energization of the electrochromic layer is stopped or a reverse voltage is applied to accelerate the color change speed thereof.
