Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic view of a housing according to an embodiment of the present disclosure; fig. 2 is a partial structural schematic diagram of the housing in fig. 1. And the present application provides a casing 100, the casing 100 may be, but not limited to, an appearance component exposed to the outside and observable by a user, such as a battery cover and a frame of the electronic device 1. It is understood that in other embodiments, the housing 100 may not be an exterior component. The housing 100 includes a first accommodating portion 110, a flow channel portion 120, a first electrode 130, and a second electrode 140. The first container portion 110 is filled with an electrolyte 126 and a first liquid metal 116, and the first container portion 110 includes a first container end 111 and a second container end 112. The flow path portion 120 includes a first connection end 120a and a second connection end 120b, the first connection end 120a is communicated with the first accommodation end 111, the second connection end 120b is communicated with the second accommodation end 112, and the flow path portion 120 is filled with the electrolyte 126, wherein decoration pieces 127 are distributed in the electrolyte 126. The first electrode 130 is disposed at the first accommodating end 111. The second electrode 140 is disposed at the second accommodating end 112, and when a first preset voltage is applied to the first electrode 130 and the second electrode 140, and the first electrode is a first polarity and the second electrode 140 is a second polarity, the first liquid metal 116 moves along the first accommodating end 111 toward the second accommodating end 112, so as to drive the decoration 127 to move in the first direction in the flow channel portion 120.
The housing 100 is made of a light-transmitting material, such as glass or plastic. The light transmittance of the housing 100 is greater than or equal to a predetermined light transmittance. For example, the predetermined transmittance may be, but is not limited to, 80%.
In one embodiment, the portions of the housing 100 corresponding to the first accommodating portion 110 and the flow channel portion 120 are made of a light-transmitting material. In other embodiments, a portion of the housing 100 corresponding to the first accommodating portion 110 or the flow channel portion 120 is made of a light-transmitting material, and other portions are made of a non-light-transmitting material. The housing 100 may be made of a light-transmitting material corresponding to the first accommodating portion 110 or the flow channel portion 120, and may be designed according to the design and appearance of the housing 100.
The first connecting end 120a of the flow path portion 120 is communicated with the first receiving end 111, and the second connecting end 120b is communicated with the second receiving end 112, so that the first receiving portion 110 and the flow path portion 120 form a communicating channel.
The first accommodating portion 110 and the flow channel portion 120 may be disposed in the substrate 10a, or disposed on the surface of the substrate 10 a. When the first accommodating portion 110 and the flow path portion 120 are disposed in the substrate 10a, the substrate 10a is more integrated. When the first accommodating portion 110 and the flow path portion 120 are disposed on the surface of the substrate 10a, the first accommodating portion 110 is convenient to form on the flow path portion 120.
In one embodiment, when the first accommodating portion 110 and the flow path portion 120 are disposed on the surface of the substrate 10a, the first accommodating portion 110 and the flow path portion 120 may be formed by using an integral film (e.g., plastic), and then the first accommodating portion 110 and the flow path portion 120 are fixed on the substrate 10 a. In another embodiment, when the first accommodating portion 110 and the flow path portion 120 are disposed on the surface of the substrate 10a, two or more films may be used to be joined together to form the first accommodating portion 110 and the flow path portion 120. The first receiving portion 110 and the flow channel portion 120 may be fixed to the substrate 10a by, but not limited to, glue, a snap structure, and the like. In the schematic view of the present embodiment, the first accommodating portion 110 and the flow path portion 120 are both disposed on the substrate 10 a.
The electrolyte 126 filled in the first accommodating portion 110 may be, but is not limited to, a sodium hydroxide solution, a sodium bicarbonate solution, and a sodium carbonate solution. The liquid metal can be, but is not limited to, gallium indium tin alloy and eutectic gallium indium alloy. In the following embodiments, the electrolyte 126 is a sodium hydroxide solution, and the first liquid metal 116 is a gallium indium tin alloy.
The radial dimension of the first receptacle 110 is greater than the radial dimension of the first liquid metal 116, but the radial dimension of the first receptacle 110 cannot be much greater than the radial dimension of the first liquid metal 116. If the radial dimension of the first accommodating portion 110 is too large than the radial dimension of the first liquid metal 116, when the first liquid metal 116 moves along the first accommodating end 111 toward the second accommodating end 112, the electrolyte 126 in the first accommodating portion 110 may not drive the decoration 127 in the flow path portion 120 to move well, or even drive the decoration 127 in the flow path portion 120 to move. The radial dimension of the first receiving portion 110 refers to a dimension of the first receiving portion 110 in a direction perpendicular to an extending direction of the first receiving portion.
The decoration 127 may be, but not limited to, an object having a variable color or a specific color, or the like, or a reflective object having a color, such as fluorescent powder, pigment powder, or the like. For example, when the decoration 127 is an object with variable color, the decoration 127 may have a specific color when light is irradiated onto the decoration 127, or different colors at different angles. The shape of the decoration 127 may be a particle shape, a block shape, a sheet shape, etc., and the shape of the decoration 127 is not limited herein as long as it has a decorative effect. In order to ensure the flowing effect, the size of the decoration 127 is in the range of 10-100 μm. When the decoration 127 moves in the flow passage, the housing 100 may exhibit a flowing colorful effect, thereby improving the appearance recognition degree of the housing 100.
In one embodiment, the first polarity is a positive electrode, and the second polarity is a negative electrode. It is understood that in other embodiments, the first polarity may be a negative polarity and the second polarity may be a positive polarity, depending on the first liquid metal 116.
The following describes in detail the case 100 where the first liquid metal 116 drives the decoration 127 to move in the flow passage.
Referring to fig. 3, 4 and 5, fig. 3 is a schematic diagram illustrating the principle of the case shown in fig. 1 and 2 when no voltage is applied to the first electrode and the second electrode; FIG. 4 is a schematic diagram of the housing shown in FIGS. 1 and 2 with the first electrode having a first polarity and the second electrode having a second polarity; fig. 5 is a schematic diagram of the movement of the first liquid metal when the first electrode and the second electrode in the housing shown in fig. 1 and 2 are applied with the first predetermined voltage, and the first electrode is of the first polarity and the second electrode is of the second polarity. When the first liquid metal 116 is placed in the electrolyte 126, the first liquid metal 116 reacts with the electrolyte 126 to form a metal oxide film. When the first electrode 130 and the second electrode 140 are not applied with voltage, the surface tension of each region of the first liquid metal 116 is the same. When the first electrode 130 and the second electrode 140 are applied with a first predetermined voltage, and the first electrode 130 has a first polarity, and the second electrode 140 has a second polarity, the electric charge on the surface of the first liquid metal 116 is shifted by coulomb force, so that the electric charge distribution on the interface between the first liquid metal 116 and the electrolyte 126 is not uniform, and under the action of the electric field, at the end of the first liquid metal 116 adjacent to the first electrode 130, the metal oxide film on the first liquid metal 116 reacts with the electrolyte 126 to be gradually dissolved, so that the oxide film at the end of the first liquid metal 116 adjacent to the first electrode 130 is gradually reduced, and the surface tension is gradually increased; accordingly, the first liquid metal 116 is adjacent to one end of the second electrode 140, and the metal in the first liquid metal 116 reacts with the electrolyte 126 to further form a metal oxide film, with gradually reduced surface tension. The difference in surface tension of the end of the first liquid metal 116 adjacent the first electrode 130 and the surface tension of the end of the first liquid metal 116 adjacent the second electrode 140 provides a motive force for movement of the first liquid metal 116 such that the first liquid metal 116 moves toward the second electrode 140, i.e., such that the first liquid metal 116 moves in a direction along the first containment end 111 toward the second containment end 112. When the first liquid metal 116 moves along the first receiving end 111 toward the second receiving end 112, the decoration 127 is driven to move inside the flow channel.
The difference in surface tension of the end of the first liquid metal 116 adjacent the first electrode 130 and the surface tension of the end of the first liquid metal 116 adjacent the second electrode 140 provides a motive force for movement of the first liquid metal 116, in particular, the resultant force between the tangential force of the surface tension of the end of the first liquid metal 116 adjacent the first electrode 130 (i.e., the force in the direction of the first containment end 111 and the second containment end 112) and the surface tension of the end of the first liquid metal 116 adjacent the second electrode 140, and inward, provides a motive force for movement of the first liquid metal 116.
The first electrode 130 and the second electrode 140 are applied with a first predetermined voltage to form a voltage difference between the first receiving end 111 and the second receiving end 112, so as to form an electric field. The voltage difference may be, but is not limited to, 5V, 10V, 15V, etc. Next, the electrolyte 126 is a sodium hydroxide solution, the first liquid metal 116 is a gallium indium tin alloy, the first polarity is a positive polarity, and the second polarity is a negative polarity.
When the gallium indium tin alloy is put into the sodium hydroxide solution, the gallium indium tin alloy reacts with the sodium hydroxide solution, and the gallium indium tin alloy on the surface reacts with the sodium hydroxide solution to form gallium oxide (Ga)2O3) And (3) a membrane. When the first electrode 130 and the second electrode 140 are loaded with a first predetermined voltage, and the first electrode 130 is a positive electrode and the second electrode 140 is a negative electrode, the charge on the surface of the gallium indium tin alloy is shifted under the coulomb force, so that the charge distribution on the interface of the gallium indium tin alloy and the sodium hydroxide solution is not uniform, and under the action of the electric field, the gallium indium tin alloy and one end of the gallium oxide film on the surface thereof, which is adjacent to the positive electrode, react with the sodium hydroxide to gradually dissolve, specifically:
Ga2O3+2NaOH+3H2O→2NaGa(OH)4 (1)
since the gallium indium tin alloy and the end of the gallium oxide film on the surface thereof adjacent to the positive polarity react with sodium hydroxide to be gradually dissolved, the surface tension is gradually increased.
The end of the gallium indium tin alloy and the gallium oxide film on the surface thereof, which is adjacent to the cathode, can be contacted with OH in the sodium hydroxide solution-The reaction is carried out to generate a gallium oxide film, specifically:
2Ga+6OH-→Ga2O3+3H2O+6e- (2)
the gallium indium tin alloy and one end of the gallium oxide film on the surface thereof, which is adjacent to the cathode, can react with OH in the sodium hydroxide solution-The reaction proceeds to produce a gallium oxide film, and therefore, the surface tension gradually decreases.
The difference in surface tension between the end of the gallium indium tin alloy adjacent to the first electrode 130 and the end of the gallium indium tin alloy adjacent to the second electrode 140 provides a motive force for the movement of the gallium indium tin alloy such that the gallium indium tin alloy moves toward the second electrode 140, i.e., the gallium indium tin alloy moves along the first containment end 111 toward the second containment end 112. When the ga-in-sn alloy moves along the direction from the first containing end 111 to the second containing end 112, the decoration 127 is further driven to move inside the flow channel.
It should be noted that, the liquid alloy is moved by utilizing the difference of the surface tension of the end of the liquid alloy adjacent to the first electrode 130 and the end adjacent to the second electrode 140, which is also referred to as continuous electrowetting effect. The continuous electrowetting effect is a transient two-phase flow driven by the interfacial tangency between the first liquid metal 116 and the electrolyte 126, i.e., the wetting force is generated by the decoded surface tension gradient, resulting in a liquid flow effect.
It should be noted that, in general, the density of the first liquid metal 116 is greater than the density of the electrolyte 126, so that the first liquid metal 116 is not easily dispersed into the electrolyte 126 when moving, and the effect of driving the electrolyte 126 to move when the first liquid metal 116 moves is better.
In this embodiment and the following embodiments, the first polarity is a positive electrode and the second polarity is a negative electrode, but it is understood that in other embodiments, depending on the electrolyte 126 and the first liquid metal 116, the first polarity may be a negative electrode and the second polarity may be a positive electrode.
The embodiment of the application provides a casing 100, work as first electrode 130 reaches second electrode 140 loads the first voltage of predetermineeing, just first electrode 130 is for anodal just under the second electrode 140 is the negative pole's the condition, first liquid metal 116 along first holding end 111 is held the direction motion of end 112 towards the second to the drive decoration 127 is in with the first direction motion in runner portion 120, thereby makes casing 100 demonstrates the flowing colorful effect that dazzles, and then has promoted casing 100's outward appearance discernment degree.
Referring to fig. 5 and 6, fig. 6 is a schematic diagram illustrating the movement of the first liquid metal when the first electrode and the second electrode of the casing shown in fig. 1 and 2 are loaded with a second predetermined voltage, and the first electrode has a second polarity and the second electrode has a first polarity. In this embodiment, the housing 100 further includes a first valve 150 and a second valve 160. The first valve 150 is disposed adjacent the first receiving end 111. The second valve 160 is disposed adjacent to the second receiving end 112, the first valve 150 and the second valve 160 are opened when the first liquid metal 116 moves along the first receiving end 111 in a direction toward the second receiving end 112, and the first valve 150 and the second valve 160 are closed when the first liquid metal 116 moves along the second receiving end 112 in a direction toward the first receiving end 111.
The first valve 150 and the second valve 160 are both one-way valves, and when the first liquid metal 116 moves along the direction from the first containing end 111 to the second containing end 112, both the first valve 150 and the second valve 160 are opened, so that the movement of the first liquid metal 116 can drive the electrolyte 126 in the first containing portion 110 to move, and further drive the electrolyte 126 in the flow channel portion 120 to move in the first direction in the flow channel portion 120. In the case where the first liquid metal 116 moves in the direction of the second receiving end 112 toward the first receiving end 111, the first valve 150 and the second valve 160 are closed, so that the electrolyte 126 in the flow channel part 120 cannot move in the direction opposite to the first direction within the flow channel. It can be seen that the arrangement of the first valve 150 and the second valve 160 can control the flowing direction of the electrolyte 126 in the flow channel portion 120.
In one embodiment, when a second predetermined voltage is applied to the first electrode 130 and the second electrode 140, and the first electrode 130 has a second polarity and the second electrode 140 has a first polarity, the first liquid metal 116 moves along the second receiving end 112 toward the first receiving end 111 in the first receiving portion 110 to return to the original position. This stage corresponds to the resetting process of the first liquid metal 116.
In one embodiment, when the first liquid metal 116 moves along the first receiving end 111 towards the second receiving end 112, when moving to a position adjacent to the second valve 160, the first electrode 130 and the second electrode 140 are controlled to be loaded with a second predetermined voltage, and the first electrode 130 is of a second polarity and the second electrode 140 is of a first polarity, such that the first liquid metal 116 moves along the second receiving end 112 towards the first receiving end 111.
When the first electrode 130 and the second electrode 140 are loaded with a second predetermined voltage, and the first polarity 130 is a second polarity and the second electrode 140 is a first polarity, the movement principle when the first liquid metal 116 moves along the direction from the second accommodating end 112 to the first accommodating end 111 refers to the aforementioned distance that the first liquid metal 116 moves along the direction from the first accommodating end 111 to the second accommodating end 112, which is not described herein again.
The first electrode 130 and the second electrode 140 are applied with a second predetermined voltage to form a voltage difference between the first receiving end 111 and the second receiving end 112, so as to form an electric field. The voltage difference may be, but is not limited to, 5V, 10V, 15V, etc. It can be understood that the voltage value of the second preset voltage may be the same as or different from the voltage value of the first preset voltage. When a second preset voltage is applied to the first electrode 130 and the second electrode 140, the polarity of the first electrode 130 is a second polarity, and the polarity of the second electrode 140 is a first polarity; when a first preset voltage is applied to the first electrode 130 and the second electrode 140, the polarity of the first electrode 130 is a first polarity, and the polarity of the second electrode 140 is a second polarity.
It can be seen that the polarity of the first electrode 130 when the first electrode 130 and the second electrode 140 are applied with the second preset voltage is opposite to the polarity of the first electrode 130 when the first electrode 130 and the second electrode 140 are applied with the first preset voltage; similarly, the polarity of the second electrode 140 when the first electrode 130 and the second electrode 140 are applied with the second predetermined voltage is opposite to the polarity of the second electrode 140 when the first electrode 130 and the second electrode 140 are applied with the second predetermined voltage.
In the case where the first liquid metal 116 moves along the second receiving end 112 toward the first receiving end 111, the first valve 150 and the second valve 160 are closed, so that the electrolyte 126 in the flow channel part 120 cannot move in the flow channel in the direction opposite to the first direction; as can be seen, in the present embodiment, the movement of the electrolyte 126 within the reservoir is intermittent.
When the first electrode 130 and the second electrode 140 are periodically applied with a voltage, specifically, the time for controlling the first electrode 130 and the second electrode 140 includes a plurality of periods T, and one period T includes a first time period T1 and a second time period T2. In a first time period t1, the first electrode 130 and the second electrode 140 are applied with a first predetermined voltage, the first electrode 130 has a first polarity and the second electrode 140 has a second polarity, the first liquid metal 116 moves along the first accommodating end 111 toward the second accommodating end 112, the first valve 150 and the second valve 160 are opened, the electrolyte 126 moves in the flow path portion 120, and the decoration 127 is driven to move in the flow path portion 120 in the first direction. In a second time period t2, when the first electrode 130 and the second electrode 140 are applied with a second predetermined voltage, the first polarity 130 is a second polarity and the second electrode 140 is a first polarity, the first liquid metal 116 moves along the second receiving end 112 toward the first receiving end 111, the first valve 150 and the second valve 160 are closed, the electrolyte 126 cannot move in the flow channel, and the decoration 127 cannot move. It can be seen that the movement of the electrolyte 126 in the housing is intermittent.
Specifically, please refer to fig. 7, fig. 7 is a circuit diagram of an electronic device with a housing according to an embodiment of the present disclosure. In an embodiment, the electronic device 1 to which the housing 100 is applied includes a controller 800 and a voltage generator 900. The voltage generator 900 includes a first terminal 910 and a second terminal 920. The voltage generator 900 is configured to generate a first preset voltage and a second preset voltage. The first end 910 is electrically connected to the first electrode 130, and the second end 920 is electrically connected to the second electrode 140. The controller 800 is electrically connected to the voltage generator 900, and is configured to control the voltage generator 900 to output the first preset voltage and the second preset voltage.
It is understood that the controller 800 and the voltage generator 900 may also be devices external to the electronic apparatus 1. For convenience of control, the voltage value of the first preset voltage is equal to the voltage value of the second preset voltage. In one embodiment, the first predetermined voltage value is not equal to the second predetermined voltage value.
Referring to fig. 2, the housing 100 further includes a first connecting portion 1100 and a second connecting portion 1200. The first connection portion 1100 connects the first connection end 120a and the first accommodating portion 111, and a radial dimension of the first connection portion 1100 is smaller than a radial dimension of the flow path portion 120 and smaller than a radial dimension of the first accommodating portion 110. The second connection portion 1200 connects the second receiving portion 112 and the second end 920, and a radial dimension of the second connection portion 1200 is smaller than a radial dimension of the flow path portion 120 and smaller than a radial dimension of the first receiving portion 110.
Referring further to fig. 2, the first valve 150 is disposed at the first receiving end 111, and the second valve 160 is disposed at the second connecting end 120 b.
Referring to fig. 2, the size of the first accommodating portion 110 in the direction perpendicular to the extending direction of the first accommodating portion 110 is larger than the size of the channel portion 120 in the direction perpendicular to the flowing direction of the filling liquid. In other words, the radial dimension of the first accommodating portion 110 is larger than the radial dimension of the flow passage portion 120. The radial dimension of the first accommodating portion 110 is larger than the radial dimension of the flow channel portion 120, so that the first liquid metal 116 can be driven to move in the flow channel portion 120 for a second stroke when moving in the first accommodating portion 110, wherein the second stroke is larger than the first stroke. In other words, a smaller movement stroke of the first liquid metal 116 in the first accommodating portion 110 can drive the electrolyte 126 to move a larger movement stroke in the flow channel portion 120. Therefore, the colorful effect of the shell 100 can be further improved, and the appearance identification degree of the shell 100 can be further improved.
Referring to fig. 8, fig. 8 is a schematic diagram illustrating the marks of the parts in the flow channel portion of the housing shown in fig. 1. The runner section 120 further includes a first sub-runner section 121, a plurality of runner units 122, and a second sub-runner section 123.

One end of the second sub flow path part 123 is connected to the other ends of the flow path units 122, and the other end of the second sub flow path part 123 is connected to the second connection end 120 b.
In this embodiment, the extending direction of the first sub-channel portion 121 deviates from the first accommodating portion 110, and therefore, the first sub-channel portions 121 are distributed on the housing 100 in the direction deviating from the first accommodating portion 110, and when the first liquid metal 116 in the first accommodating portion 110 flows, the electrolyte 126 in the first sub-channel portion 121 is driven to move, and further the decoration 127 in the electrolyte 126 is driven to move. The first accommodating portion 110 extends along a first extending direction, and the first sub-channel portion 121 extends along a second extending direction. In one embodiment, the first extending direction is an X direction, and the second extending direction is a Y direction. The first sub-channel part 121 is disposed so that the housing 100 can exhibit a flowing colorful effect in the second extending direction, thereby improving the appearance identification degree of the housing 100 in the second extending direction. In addition, the flow channel portion 120 includes a plurality of flow channel units 122, and an extending direction of at least some of the flow channel units 122 is the same as the extending direction of the first accommodating portion 110 or is a preset included angle, that is, at least some of the flow channel units 122 are disposed along the first extending direction or a direction that is a preset included angle with the first extending direction. The preset included angle may be, but is not limited to, 10 ° or 30 °, and the like, and is not limited herein. Therefore, the arrangement of the flow channel unit 122 can enable the housing 100 to exhibit a flowing colorful effect in a direction which is a preset included angle along the first extending direction or with the first extending direction, so as to improve the appearance identification degree of the housing 100 in the first extending direction or in the direction which is the preset included angle with the first extending direction.
Further, in one embodiment, the flow path unit 122 includes a first branch 1221, a second branch 1222, and a third branch 1223. The first branch 1221 and the second branch 1222 are bent and connected, the third branch 1223 and the second branch 1222 are bent and connected, the first branch 1221 and the third branch 1223 are disposed on the same side of the second branch 1222, an extending direction of the first branch 1221 is the same as an extending direction of the first accommodating portion 110 or is a first preset included angle, an extending direction of the second branch 1222 is the same as an extending direction of the first accommodating portion 110 or is a second preset included angle, and the second branch 1222 is opposite to the first sub-channel 121.
It can be understood that, when the extending direction of the first branch 1221 and the extending direction of the first accommodating portion 110 are arranged at a predetermined included angle, the first predetermined included angle is defined; when the extending direction of the second branch 1222 and the extending direction of the first accommodating portion 110 form a predetermined included angle, the second predetermined included angle is a second predetermined included angle, wherein the first predetermined included angle may be the same as or the same as the first predetermined included angle.
In this embodiment, the first branch 1221 and the third branch 1223 are respectively connected to the second branch 1222 in a bent manner, and the first branch 1221 and the third branch 1223 are disposed on the same side of the second branch 1222, that is, the flow path unit 122 includes a plurality of bent branches. Compared with the flow channel unit 122 without the bent branches, the distribution density of the flow channel unit 122 in the housing 100 is higher, and when the electrolyte 126 drives the decoration 127 to move in the flow channel unit 122, the colorful effect can be further improved, and the appearance identification degree of the housing 100 can be further improved.

When the first liquid metal 116 moves along the second receiving end 112 toward the first receiving end 111, the first valve 150 and the second valve 160 are closed, and the electrolyte 126 in the flow channel 120 cannot enter the first receiving portion 110 through the first valve 150 and the second valve 160. In this case, a third preset voltage is applied to the third electrode 180 and the fourth electrode 190, the third electrode 180 has a second polarity and the fourth electrode 190 has a first polarity, the second liquid metal 176 moves along the fourth accommodating end 170b toward the third accommodating end 170a, so that the electrolyte 126 in the second accommodating portion 170 moves along the third accommodating end 170a toward the fourth accommodating end 170b, and the electrolyte 126 in the flow channel portion 120 is driven to flow into the second accommodating portion 170, so that the decoration 127 moves along with the electrolyte 126 in the flow channel portion 120 in the second direction in the flow channel portion 120.
