Referring to fig. 5, the zoom film 230 includes a first light-transmitting film 231, a second film 232, a flexible diaphragm 233 and a spacer 234, the first light-transmitting film 231 and the second film 232 are disposed opposite to each other, the flexible diaphragm 233 is disposed between the first light-transmitting film 231 and the second film 232 and has a space between the first light-transmitting film 231 and the second film 232, and the spacer 234 is connected between the flexible diaphragm 233 and the first light-transmitting film 231 and between the flexible diaphragm 233 and the second film 232. The spacer 234 does not entirely cover the space between the flexible diaphragm 233 and the first light-transmitting film layer 231, and the space between the flexible diaphragm 233 and the second film layer 232. A first cavity 235 is formed between the flexible membrane 233 and the first light transmissive film layer 231, and a second cavity 236 is formed between the flexible membrane 233 and the second film layer 232.
The first light-transmitting film layer 231, the second film layer 232 and the flexible membrane 233 are all substantially planar, wherein the first light-transmitting film layer 231 and the second film layer 232 may be made of hard materials, so that the zoom film 230 may be formed by preparation, and in a more specific embodiment, the first light-transmitting film layer 231 and the second film layer 232 may be made of the same materials, so that the first light-transmitting film layer 231 and the second film layer 232 have the same refractive index, and when light passes through the first light-transmitting film layer 231 and the second film layer 232, the original path of the light may be maintained without deflection. More specifically, the first light-transmitting film layer 231 and the second film layer 232 may be made of polyethylene terephthalate (polyethylene terephthalate, PET). The flexible diaphragm 233 may be deformed by an external force, so that the curvature of the flexible diaphragm 233 may be changed, so that the flexible diaphragm 233 may converge or diverge light, and thus the focal length of the zoom diaphragm 230 may be changed. In this embodiment, the flexible separator 233 may be made of a polymer film, for example, polypropylene, polycarbonate, or the like.
With continued reference to fig. 5, the spacer 234 is mainly used to connect and fix the first transparent film 231, the second film 232 and the flexible diaphragm 233, and also to seal the first cavity 235 and the second cavity 236. The spacer 234 may be, for example, a frame glue, and the first light-transmitting film 231, the second film 232, and the flexible diaphragm 233 are fixed by bonding. By controlling the configuration of the spacer 234, the spatial configuration of the first and second cavities 235, 236 may be varied. In a more specific embodiment, as shown in FIG. 5, the spacer 234 connected between the flexible membrane 233 and the second membrane layer 232 is disposed primarily along the edges of the flexible membrane 233 and the second membrane layer 232, where the cross-sectional area of the second cavity 236 is approximately comparable to the cross-sectional area of the flexible membrane 233. The spacer 234 connected between the flexible membrane 233 and the first light transmissive film layer 231 is disposed primarily along the edges of the flexible membrane 233 and the first light transmissive film layer 231, where the cross-sectional area of the first cavity 235 is approximately comparable to the cross-sectional area of the flexible membrane 233. The volumes of the first chamber 235 and the second chamber 236 are substantially the same.
The liquid storage bag 220 can be made of a material with a certain elasticity, so that the liquid storage bag 220 can have a certain deformation characteristic, and the liquid storage bag 220 can be stretched to realize volume expansion.
The first cavity 235 is communicated with the liquid storage bag 220, and the first cavity 235 and the liquid storage bag 220 are filled with a light-transmitting liquid 237, wherein the light-transmitting liquid 237 is a liquid substance with a larger refractive index, the refractive index of the light-transmitting liquid 237 can be greater than or equal to 1, and further, the refractive index of the light-transmitting liquid 237 can be greater than or equal to 1.3-1.5. The flexible diaphragm 233 has a certain elasticity and can be deformed. The second cavity 236 may be filled with a gas, for example, air, and since air is compressible and transparent to visible light, when the volume of the transparent liquid 237 in the first cavity 235 changes, the pressure balance on both sides of the flexible diaphragm 233 changes, and the flexible diaphragm 233 deforms. In particular, the second chamber 236 may be filled with an inert gas, such as helium (He), argon (Ar), nitrogen (N) 2 ) Etc. The advantage of filling inert gas is that the gas is purer, so the impurity is less, and the scattering or deflection of light can be reduced.
The first transparent film 231 may be transparent to light, in one embodiment, the second film 232 may be non-transparent, the second film 232 may be a textured layer with textures formed thereon, and the textures on the second film 232 may be visible from the outside of the electronic device 10 through the transparent cover 210, and it should be noted that the textures on the second film 232 may be arranged in any form. In another embodiment, the side of the second film 232 facing the second cavity 236 is provided with a pattern, and the pattern on the second film 232 can be visually observed from the outside of the electronic device 10 through the light-transmitting cover plate 210.
In the zoom film 230 shown in fig. 5, the flexible diaphragm 233 is in a planar configuration, which corresponds to a planar lens, so that no matter what light l is incident from the direction of the first light-transmitting film 231 b Light ray l entering from the direction of the second film layer 232 a All propagate in a straight direction while passing through the flexible diaphragm, and at this time, the focal length of the zoom film 230 is not changed, and the pattern or texture on the second film 232, which is observed by the user from the side of the first light-transmitting film 231, is the same as the actual size.
As shown in fig. 6, when the external force drives the light-transmitting liquid 237 in the first cavity 235, the light-transmitting liquid 237 may enter the liquid reservoir 220, at this time, the light-transmitting liquid 237 in the first cavity 235 decreases, the flexible diaphragm 233 expands toward the first light-transmitting film 231, and the edge of the flexible diaphragm 233 is fixed to the second film 232 via the spacer 234, so that the flexible diaphragm 233 forms an arc shape toward the first light-transmitting film 231 as a whole, and at this time, the focal length of the zoom film 230 changes. The zoom film 230 corresponds to a reduced mirror, and the pattern or texture on the second film 232 viewed from the first transparent film 231 side by the user is reduced compared to the actual size.
As shown in fig. 7, when the external force drives the light-transmitting liquid 237 in the liquid storage bag 220, the light-transmitting liquid 237 can enter the first cavity 235, at this time, the light-transmitting liquid 237 in the first cavity 235 increases, the flexible diaphragm 233 expands toward the second film 232, and the edge of the flexible diaphragm 233 is fixed to the second film 232 by the spacer 234, so that the flexible diaphragm 233 forms an arc shape toward the second film 232 as a whole, and at this time, the focal length of the zoom film 230 changes. The zoom film 230 corresponds to a magnifying lens, and the pattern or texture on the second film 232 viewed from the first light-transmitting film 231 side by the user is magnified compared to the actual size.
If necessary, the surface of the first light-transmitting film layer 231 far from the second film layer 232 may be attached to the inner surface 202 of the light-transmitting cover plate 210, or the surface of the second film layer 232 far from the first light-transmitting film layer 231 may be attached to the inner surface 202 of the light-transmitting cover plate 210. In this embodiment, the surface of the first transparent film 231 far from the second film 232 is adhered to the inner surface 202 of the transparent cover 210, so that the first cavity 235 is closer to the transparent cover 210, and the pattern or texture on the second film 232 is easier to see from the outer surface 203 side of the transparent cover 210.
The light-transmitting liquid 237 is driven by an external force, and the distribution of the light-transmitting liquid 237 in the first cavity 235 and the liquid storage bag 220 is adjusted, so that the zoom film 230 can be switched among the plane lens, the reduction mirror and the magnifying lens. When the zoom film 230 is a planar lens, the volume of the first cavity 235 visually observed from the outer surface 203 side of the light-transmitting cover plate 210 is the same as the actual volume. With reference to the foregoing and fig. 8, when the transparent liquid 237 is kept in balance between the first cavity 235 and the reservoir 220, the pattern or texture on the second film 232 as seen from the outer surface 203 of the transparent cover 210 is a normal image as shown in fig. 8 (b). When the light-transmitting liquid 237 enters the reservoir 220 from the first cavity 235, as shown in fig. 8 (a), the image of the pattern or texture on the second film 232 as seen from the outer surface 203 side of the light-transmitting cover plate 210 is reduced. When the light-transmitting liquid 237 enters the first chamber 235 from the reservoir 220, as shown in fig. 8 (c), the image of the pattern or texture on the second film 232 as seen from the outer surface 203 side of the light-transmitting cover plate 210 is magnified. During the curvature change of the flexible membrane 233 of the variable focus diaphragm 230, the pattern or texture image on the second film 232 is visually changed dynamically from the side of the outer surface 203 of the light transmissive cover plate 210.
In another embodiment, the user can also change the distribution of the transparent liquid 237 in the first cavity 235 and the liquid reservoir 220 by pressing the position of the transparent cover 210 corresponding to the first cavity 235 or the liquid reservoir 220, so that the shape of the flexible membrane 233 can be changed, and further dynamic change of the pattern or the texture image on the second membrane 232 can be realized.
In order to enable the housing to have a function of interaction with a user, in this embodiment, referring to fig. 9, the first cavity 235 has a first communication port 2351 and a second communication port 2352, and both the first communication port 2351 and the second communication port 2352 are in communication with the liquid reservoir 220. The variable focus diaphragm 230 may further comprise a first micro pump 238 and a second micro pump 239, the first micro pump 238 being arranged at the first communication port 2351 and being adapted to pump the light transmissive liquid 237 within the first cavity 235 towards the reservoir 220. The second micropump 239 is disposed at the second communication port 2352 and configured to pump the light-transmitting liquid 237 in the liquid reservoir 220 toward the first cavity 235. By controlling the opening or closing of the first micropump 238 and the second micropump 239, the amount of the light-transmitting liquid 237 in the first cavity 235 can be changed in real time, so that the curvature of the flexible diaphragm 233 is changed, and the patterns or textures on the second film 232 visually observed from the outer surface 203 side of the light-transmitting cover plate 210 are dynamically changed, so that a shell with richer colors and patterns is formed.
The first micro pump 238 and the second micro pump 239 may employ a pump with a solenoid valve, and when the first micro pump 238 and the second micro pump 239 are in a closed state, the solenoid valve is closed, thereby blocking the first communication port 2351 and the second communication port 2352, and at this time, the light-transmitting liquid 237 in the first chamber 235 and the liquid reservoir 220 will no longer flow to each other. In another embodiment, the first micropump 238 and the second micropump 239 may be conventional pumps without electromagnetic valves, in which case a first valve 241 may be disposed between the first communication port 2351 and the reservoir 220, and a second valve 242 may be disposed between the second communication port 2352 and the reservoir 220, and the first valve 241 and the second valve 242 may be used to block or communicate with the first communication port 2351 and the second communication port 2352, respectively. The first valve 241 and the second valve 242 may be, for example, solenoid valves, and may be electrically connected to a motherboard of the electronic device 10 to operate under control instructions of the motherboard.
Further, by controlling the first micropump 238 and the second micropump 239, the volume of the first cavity 235 is changed in a predetermined manner, and the method can also be used for man-machine interaction. For example: when the electronic device 10 receives the information or message, the volume of the first chamber 235 is continuously increased or decreased by controlling the first micropump 238 and the second micropump 239 to be turned on or off, so as to prompt the user. Of course, the above-described interaction is merely an example, and is not intended to be limiting.
In another embodiment, referring to fig. 10 and 11 together, the first chamber 235 may further include a plurality of sub-chambers 2353, and the plurality of sub-chambers 2353 may communicate with each other through a pipe 2354 such that each sub-chamber 2353 has the same hydraulic pressure. The hydraulic pressure in the entire first chamber 235 is the same during the flow of the light transmissive liquid 237, so that the pressure experienced by the flexible membrane 233 from the light transmissive liquid 237 in the first chamber 235 is equal throughout, and the curvature of the flexible membrane 233 can remain continuous. By dividing the first cavity 235 into a plurality of sub-cavities 2353, more interaction modes and more varied effects can be formed in the process of dynamic interaction.
Each sub-cavity 2353 may be independently configured in any shape, and a plurality of sub-cavities 2353 may be independently configured in a circular shape, a star shape, a polygonal shape, or the like, without limitation. The plurality of sub-cavities 2353 may be arranged in a predetermined arrangement, for example, in a rectangular array, a circular array, or in a predetermined pattern. Note that, the shape of the sub-cavity 2353 refers to the shape of the front projection of the sub-cavity 2353 on the inner surface 202 of the transparent cover plate 210. As just one example, as shown in fig. 11, each sub-cavity 2353 is configured in a circular shape, and a plurality of sub-cavities 2353 are arranged to form a heart shape.
In one embodiment, a plurality of patterns are disposed on a side of the second film 232 facing the second cavity 236, and the plurality of patterns are disposed in a one-to-one correspondence with the plurality of sub-cavities 2353, so that each pattern can be displayed from one sub-cavity 2353, and the pattern on the second film 232 can be visually changed dynamically from the side of the outer surface 203 of the transparent cover 210. In this arrangement, the patterns may be identical or different, or partially identical, so that the pattern design may be more varied, and the interaction effect formed may be varied.
As shown in fig. 12, when the external force drives the light-transmitting liquid 237 in the first cavity 235, the light-transmitting liquid 237 may enter the liquid reservoir 220, at this time, the light-transmitting liquid 237 in each sub-cavity 2353 is reduced, the flexible membrane 233 expands toward the first light-transmitting film 231, and the flexible membrane 233 forms an arc shape toward the first light-transmitting film 231 as a whole. The zoom film 230 corresponds to a reduction mirror, and the image of each pattern on the second film 232 viewed from the first transparent film 231 side by the user is reduced.
As shown in fig. 13, when the external force drives the light-transmitting liquid 237 in the liquid storage bag 220, the light-transmitting liquid 237 can enter the first cavity 235, and at this time, the proportion of the light-transmitting liquid 237 in each sub-cavity 2353 increases, the flexible diaphragm 233 expands toward the second film 232, and the flexible diaphragm 233 forms an arc shape toward the second film 232 as a whole. The zoom film 230 corresponds to a magnifying lens formed such that the image of each pattern on the second film 232 viewed from the side of the first light-transmitting film 231 is magnified by the user.
Fig. 14 shows a state in the dynamic interaction process of the housing 200 in the present embodiment, which is visually recognized from the outer surface 203 side. Fig. 14 (b) shows a state when the flexible diaphragm 233 is in a planar configuration, fig. 14 (a) shows a contracted state when the light-transmitting liquid 237 is a contracted mirror, and fig. 14 (c) shows an expanded state when the light-transmitting liquid 237 is a magnifier.
In this embodiment, a plurality of subchambers 2353 are separated by spacers 234. When the connection member is provided, the spacers 234 are provided at predetermined positions according to the shape of the predetermined sub-cavities 2353 to form a plurality of sub-cavities 2353, which can reduce the steps of providing other structural members and simplify the manufacturing process.
The housing provided in this embodiment, through forming the first cavity 235 and the liquid storage bag 220 that are connected, and through the distribution of the light-transmitting liquid 237 is changed by the external force, thereby realizing the zooming effect of the zooming membrane 230, so as to increase the appearance effect of the housing, and can be used for performing man-machine interaction.

step S110: a first light-transmitting film layer 231 is provided, and a spacer 234 is provided on a surface of the first light-transmitting film layer 231.
When the first cavity 235 is a single cavity, the spacers 234 may be disposed along the edge of the first light-transmitting film layer 231. When the first cavity 235 includes a plurality of sub-cavities 2353, the plurality of spacers 234 may be arranged according to a predetermined arrangement manner of the sub-cavities 2353, the plurality of spacers 234 enclose the sub-cavities 2353, and keep the plurality of sub-cavities 2353 in communication, and the spacers 234 may be frame glue.

In some embodiments, the spacer 234 and the reservoir 220 may communicate with each other through the first communication port 2351 and the second communication port 2352, and in this case, the first micro pump 238 may be further disposed at the first communication port 2351, and the second micro pump 239 may be disposed at the second communication port 2352.
Step S130: a flexible membrane 233 is disposed on a surface of the plurality of spacers 234 remote from the first light-transmissive film layer 231 to form a first cavity 235 between the first light-transmissive film layer 231 and the flexible membrane 233, and the first cavity 235 is in communication with the reservoir 220.
The flexible diaphragm 233 is fixed to the spacer 234 by adhesion, and the flexible diaphragm 233 may be disposed substantially parallel to the first light-transmitting film layer 231. By controlling the thickness of the flexible membrane 233, the structural strength of the flexible membrane 233 can be varied, and the flexible membrane 233 can be kept in a just-in-plane state without the first cavity 235 and the reservoir 220 being subjected to external forces. The thickness of the flexible membrane 233 may be, for example, between 0.05-0.2 mm.

During the process of disposing the second film 232, the second chamber 236 may be filled with air, inert gas, or the like. The distance between the second film layer 232 and the flexible membrane 233 may be substantially equal to the distance between the first light-transmitting film layer 231 and the flexible membrane 233.
Step S160: the variable focus diaphragm 230 and the reservoir 220 are disposed on the surface of the transparent cover 210.

The first texture layer 250 may cover the entire inner surface 202 of the transparent cover plate 210, or may cover only a portion of the inner surface 202 of the transparent cover plate 210, which is not limited herein.
