Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to a housing and a mobile terminal. Background Technology

[0002] The casing of a mobile terminal serves to protect its internal structure. However, during device operation, the casing can affect the device's heat dissipation capacity, especially in high-power operating scenarios, which may cause the device to lag.

[0003] Therefore, there is an urgent need for a housing to reduce its impact on the heat dissipation capacity of the equipment. Summary of the Invention

[0004] This application provides a housing and a mobile terminal to solve the problem that the housing affects the heat dissipation capability of the mobile terminal.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a housing, comprising: a display unit including a light-transmitting panel and a back panel disposed opposite to each other, and a hollow cavity disposed between the light-transmitting panel and the back panel for accommodating a magnetic fluid; a driving unit including at least one driving coil disposed on the side of the hollow cavity away from the light-transmitting panel, the driving coil being used to generate a magnetic field for driving the magnetic fluid; the housing including a first region, the first region corresponding to the functional modules of a mobile terminal, at least a portion of the driving coil being located in the first region, the housing including a first heat dissipation state, and the driving unit being configured to activate the driving coil in the first region in the first heat dissipation state.

[0007] Secondly, embodiments of this application also provide a mobile terminal, including the aforementioned housing.

[0008] Thus, the housing provided in this application embodiment includes a display unit and a driving unit. The display unit includes a light-transmitting panel and a back panel disposed opposite to each other, and a hollow cavity disposed between the light-transmitting panel and the back panel for accommodating magnetic fluid. The hollow cavity stores magnetic fluid so that the pattern of magnetic fluid arrangement in the hollow cavity can be seen from the light-transmitting panel side. The driving unit includes at least one driving coil disposed on the side of the hollow cavity away from the light-transmitting panel. When the driving coil is energized, it can generate a magnetic force to attract magnetic fluid. By changing the on and off states of different driving coils, the arrangement state of magnetic fluid can be controlled, thereby enabling the magnetic fluid to present different patterns, thus improving the problem that the pattern of the housing cannot be customized by the user. The housing includes a first region corresponding to the functional modules of the mobile terminal. At least some of the driving coils are located in the first region. The housing includes a first heat dissipation state. When the housing is in the first heat dissipation state, the driving unit activates the driving coils in the first region to cause magnetic fluid to gather in the first region, thereby enhancing the heat dissipation capacity of the housing in the first region.

[0009] Therefore, this application embodiment improves the heat dissipation capacity of the housing and reduces the impact of the housing on the heat dissipation capacity of the mobile terminal by providing a display part with magnetic fluid and a driving part for driving magnetic fluid, and configuring the housing to include a first heat dissipation state.

[0026] Please refer to the following: Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of the housing 100 in some embodiments of this application. Figure 2 This is an exploded view of the housing 100 of some embodiments of this application. Figure 3 This is a schematic diagram of the housing 100 in a display state according to some embodiments of this application. Figure 4 This is a schematic diagram of the housing in a first heat dissipation state according to some embodiments of this application; Figure 5 This is a schematic diagram of the housing structure for some other embodiments of this application.

[0027] Firstly, such as Figures 1 to 5As shown, this application embodiment provides a housing 100, which includes a display unit 200 and a driving unit 300. The display unit 200 includes a light-transmitting panel 210 and a back panel 220 disposed opposite to each other, and a hollow cavity 230 disposed between the light-transmitting panel 210 and the back panel 220 for accommodating a magnetic fluid 240. The driving unit 300 includes at least one driving coil 310, which is disposed on the side of the hollow cavity 230 away from the light-transmitting panel 210 and is used to generate a magnetic field to drive the magnetic fluid 240. The housing 100 includes a first region 350, which is correspondingly disposed with the functional modules of the mobile terminal, and at least some of the driving coils 310 are located in the first region 350. The housing 100 includes a first heat dissipation state, in which the housing 100 is configured to activate the driving coils 310 in the first region 350.

[0028] Thus, in the housing 100 for a mobile terminal provided in this application embodiment, the housing 100 includes a display unit 200 and a driving unit 300. The display unit 200 includes a light-transmitting panel 210 and a back plate 220 disposed opposite to each other, and a hollow cavity 230 disposed between the light-transmitting panel 210 and the back plate 220 for accommodating magnetic fluid 240. The hollow cavity 230 stores magnetic fluid 240 so that the pattern of magnetic fluid 240 arrangement in the hollow cavity 230 can be seen from the light-transmitting panel 210 side. The driving unit 300 includes at least one driving coil 310 disposed on the side of the hollow cavity 230 away from the light-transmitting panel 210. When the driving coil 310 is energized, it can generate a magnetic force to attract the magnetic fluid 240. By changing the on and off states of different driving coils 310, the arrangement state of the magnetic fluid 240 can be controlled, thereby enabling the magnetic fluid 240 to present different patterns, thus improving the problem that the pattern of the housing 100 cannot be customized by the user. The housing 100 includes a first region 350 corresponding to the functional modules of the mobile terminal. At least some of the driving coils 310 are located in the first region 350. The housing 100 includes a first heat dissipation state. When the housing 100 is in the first heat dissipation state, the driving unit 300 activates the driving coils 310 in the first region 350 to cause the magnetic fluid 240 to gather in the first region 350, thereby enhancing the heat dissipation capacity of the housing 100 in the first region 350 and reducing the impact of the housing 100 on the heat dissipation capacity of the mobile terminal.

[0029] The material of the light-transmitting panel 210 includes light-transmitting materials, such as plexiglass or organic resin.

[0030] The backplate 220 serves to shield the drive coil 310, separate the drive coil 310 from the magnetofluid 240, and provide a background for the display of the magnetofluid 240. The backplate 220 can be a plastic plate or a glass plate. Optionally, the backplate 220 is a solid color plate; or, the backplate 220 can be customized with a pattern to enhance the display diversity of the housing 100.

[0031] The housing 100 includes a first region 350 corresponding to the functional modules of the mobile terminal. The corresponding configuration means that the first region 350 and the orthographic projection of the functional module in the first direction X overlap, or the orthographic projection of the first region 350 in the first direction X surrounds the functional module.

[0032] It is understandable that when a mobile terminal is working, its functional modules will generate heat, and the first area 350 on the housing 100 is set to correspond to these heat-generating areas.

[0033] A drive coil 310 is provided in the first region 350. In the first heat dissipation state, the drive coil 310 in the first region 350 is turned on, and the magnetic fluid 240 will be attracted to the first region 350. Since the magnetic fluid 240 has better thermal conductivity than air, the magnetic fluid 240 gathered in the first region 350 can enhance the heat exchange capacity of the first region 350, so as to better dissipate heat for the functional modules of the mobile terminal and improve the working performance of the mobile terminal.

[0034] Optionally, one or more first regions 350 can be provided on each housing 100. When multiple first regions 350 are provided, it is possible to decide how many drive coils 310 in the first regions 350 are in the open state at the same time, and to allocate the number of drive coils 310 in each first region 350 to reasonably allocate the distribution of the magnetic fluid 240 at different positions on the back plate, so as to achieve precise adjustment of the heat dissipation capacity at different positions.

[0035] Please see Figure 3 The driving unit 300 includes multiple driving coils 310, which are disposed on the side of the back plate 220 opposite to the light-transmitting panel 210. By activating different driving coils 310, the driving coils 310 generate a magnetic field along the first direction X to attract the magnetic fluid 240, causing the magnetic fluid 240 to gather into multiple points at different positions on the back plate 220. The multiple adjacent points form lines, and different lines are used to present patterns on the back plate 220. By designing the positions of the driving coils 310a in the active state and 310b in the deactivated state within the housing 100, the magnetic fluid 240 can present different patterns customized by the user, wherein the first direction X is the thickness direction of the light-transmitting panel 210.

[0036] Furthermore, after presetting the duration of the on and off states of different drive coils 310, the magnetic fluid 240 can achieve a flowing display effect on the back panel as the drive coils 310 at different positions are turned on and off, thereby realizing a dynamic pattern display on the housing 100. When user preferences change, the user can repeat the above steps to make the magnetic fluid 240 display a user-customized pattern on the back panel 220.

[0037] See also Figure 5 The housing 100 has a functional area 250 for housing functional components of the mobile terminal (such as a camera component). The specific arrangement of the functional area 250 can be designed according to the actual application scenario. Figure 3 The setting method for the middle functional area 250 is only an example.

[0038] Optionally, multiple drive coils 310 are arranged in rows and columns along the length and width of the back plate 220. The regular arrangement of drive coils 310 helps to reduce the design difficulty of the pattern.

[0039] In some alternative embodiments, such as Figure 1 and Figure 2 As shown, the driving unit 300 also includes a wiring layer 320, which is located on the side of the driving unit 300 away from the display unit 200; the driving coil 310 includes a driving member 311 and a connector 312, with the driving member 311 located on the side of the connector 312 facing the hollow cavity 230, and the connector 312 connected between the wiring layer 320 and the driving member 311.

[0040] In these optional embodiments, the drive coil 310 includes a connector 312 and a drive element 311. The drive element 311 generates a magnetic field in a first direction X to attract the magnetofluid 240. The connector 312 connects the wiring layer 320 and the drive element 311. The wiring layer 320 contains control lines for controlling the drive coil 310, making the wiring within the housing 100 neat and concise. The wiring layer 320 works in conjunction with the central processing unit of the mobile terminal to control the on and off states of each drive coil 310, allowing each drive coil 310 to be controlled independently. This improves the display versatility of the housing 100.

[0041] Please refer to the following: Figure 5 and Figure 6 , Figure 6 for Figure 1 Sectional view at point AA.

[0042] In some alternative embodiments, such as Figure 5 and Figure 6As shown, the driving unit 300 also includes a first shielding layer 330 capable of shielding at least part of the magnetic field. The first shielding layer 330 is located on the side of the wiring layer 320 close to the driving member 311 in the first direction X, where the first direction X is the thickness direction of the light-transmitting panel 210.

[0043] In these alternative embodiments, the drive unit 300 further includes a first shielding layer 330 capable of shielding at least part of the magnetic field. The first shielding layer 330 includes a first shielding layer 330 located on the side of the wiring layer 320 close to the drive member 311 in the first direction X, so as to reduce magnetic field interference between other functional modules of the mobile terminal and the housing 100, which improves the reliability of the housing 100.

[0044] Because the housing 100 is very close to other functional modules of the mobile terminal, the magnetic field generated by the drive coil 310 when it is working will interfere with the other functional modules of the mobile terminal, affecting their performance. Similarly, the magnetic fields generated by the other functional modules of the mobile terminal when they are working will also interfere with the magnetohydrodynamic fluid 240 of the housing 100, affecting its normal display. Therefore, a first shielding layer is set between the drive coil 310 and the other functional modules of the mobile terminal to reduce mutual interference between them.

[0045] Optionally, the first shielding layer 330 is made of a soft magnetic material. For example, the first shielding layer 330 is an iron-aluminum alloy or permalloy, etc.

[0046] In some alternative embodiments, the material of the first shielding layer 330 includes a soft magnetic composite material.

[0047] The first shielding layer 330 is a soft magnetic composite material. For example, the first shielding layer 330 is a carbon fiber soft magnetic composite material. The first shielding layer 330 made of soft magnetic composite material is lightweight, which can reduce the overall weight of the housing 100 and improve the user experience.

[0048] In some alternative embodiments, such as Figure 5 and Figure 6 As shown, the first shielding layer 330 is located between the wiring layer 320 and the drive unit 311.

[0049] In these alternative embodiments, the magnetic field is mainly generated by the drive unit 311 in the housing 100. By placing the first shielding layer 330 between the wiring layer 320 and the drive unit 311, the influence of the magnetic field generated by the drive unit 311 on other modules of the mobile terminal can be effectively reduced, which improves the reliability of the housing 100.

[0050] In some alternative embodiments, such as Figure 5 and Figure 6As shown, the first shielding layer 330 includes a bottom wall 331 and a side wall 332 connected to the periphery of the bottom wall 331 and extending toward the light-transmitting panel 210. The bottom wall 331 is disposed on the side of the drive member 311 away from the display section 200, and the end of the side wall 332 away from the bottom wall 331 is connected to the light-transmitting panel 210.

[0051] In these optional embodiments, the first shielding layer 330 includes a sidewall 332 disposed on the side of the drive member 311 opposite to the display section 200 and connected to the periphery of the bottom wall 331 extending toward the light-transmitting panel 210. One end of the sidewall 332 opposite to the bottom wall 331 is connected to the light-transmitting panel 210. The sidewall 332 is used to reduce the influence of the magnetic field generated by the drive coil 310 on other modules in the circumferential direction surrounding the first direction X, thereby improving the reliability of the housing 100. The sidewall 332, together with the light-transmitting panel 210 and the back plate 220, forms a chamber for storing the magnetofluid 240. Furthermore, the sidewall 332 connected to the light-transmitting panel 210 also helps to improve the structural strength of the housing 100 and increase its service life.

[0052] Optionally, the sidewall 332 is bonded to the light-transmitting panel 210 in the first direction X. The sidewall 332 serves to support the light-transmitting panel 210 and improves the bending resistance of the light-transmitting panel 210.

[0053] Optionally, the side wall 332 and the bottom wall 331 are integrally formed, or the side wall 332 and the bottom wall 331 are separately provided, and the connection method between the side wall 332 and the bottom wall 331 is one of the following: adhesive, snap-fit, bolt connection, or welding connection.

[0054] In some alternative embodiments, such as Figure 6 As shown, the thickness L of the bottom wall 331 and / or the side wall 332 is greater than or equal to 2 mm.

[0055] In these alternative embodiments, the thickness L of the bottom wall 331 and / or the side wall 332 is greater than or equal to 2 mm, in order to improve the problem that the shielding effect of the first shielding layer 330 is not up to standard due to the bottom wall 331 and / or the side wall 332 being too thin, and the driving coil 310 and other modules of the mobile terminal interfere with each other.

[0056] In some alternative embodiments, such as Figure 5 and Figure 6 As shown, the drive unit 300 also includes a second shielding layer 340, which is disposed on the side of the wiring layer 320 opposite to the light-transmitting panel 210.

[0057] In these optional embodiments, the second shielding layer 340 further includes a second shielding layer 340 disposed on the side of the wiring layer 320 away from the light-transmitting panel 210. The first shielding layer 330 is disposed between the wiring layer 320 and the driving member 311. In order to connect the driving member 311 and the wiring layer 320, the first shielding layer 330 is provided with holes for the connector 312 to pass through. These holes reduce the shielding capability of the first shielding layer 330. Therefore, the second shielding layer 340 is disposed on the side of the wiring layer 320 away from the light-transmitting panel 210. The first shielding layer 330 and the second shielding layer 340 work together to better block the mutual interference of magnetic fields between the driving coil 310 and other components of the mobile terminal, so as to improve the reliability of the housing 100.

[0058] Optionally, the second shielding layer 340 and the first shielding layer 330 are made of the same material.

[0059] Optionally, the second shielding layer 340 is thinner than the first shielding layer 330 to reduce the overall thickness of the housing 100 and enhance the grip of the mobile terminal.

[0060] Please refer to the following: Figure 5 and Figure 7 , Figure 7 This is a schematic diagram of the housing 100 in a first heat dissipation state, which is a further embodiment of this application.

[0061] In some alternative embodiments, such as Figure 5 and Figure 7 As shown, the density of the drive coil 310 in the first region 350 is greater than the density of the drive coil 310 in other regions of the housing 100.

[0062] In these embodiments, by increasing the density of the drive coils 310 in the first region 350, the magnetic field in the first region 350 is stronger when the housing 100 is in the first heat dissipation state, which can attract more and faster magnetic fluid 240, thereby further improving the heat dissipation effect of the first region 350 on the mobile terminal.

[0063] Optionally, a single drive coil 310 within the first region 350 can generate a stronger magnetic field than a single drive coil 310 outside the first region 350. Optionally, when the drive coil 310 is in the on state, the current flowing through the drive coil 310 within the first region 350 is greater than the current flowing through the drive coil 310 outside the first region 350, so that the first region 350 can generate a stronger magnetic field, enabling the first region 350 to attract more magnetofluid more quickly.

[0064] Please refer to the following: Figure 5 and Figure 8 , Figure 8 This is a schematic diagram of the housing 100 in a second heat dissipation state according to some embodiments of this application.

[0065] In some alternative embodiments, such as Figure 5 and Figure 8 As shown, the housing 100 also includes a second region 360 adjacent to the first region 350, and at least a portion of the drive coil 310 is located in the second region 360; the housing 100 also includes a second heat dissipation state, and the drive unit 300 is configured to control the drive coils 310 in the first region 350 and the second region 360 to alternately turn off and on in the second heat dissipation state.

[0066] In these optional embodiments, the housing 100 further includes a second region 360 adjacent to the first region 350, at least a portion of the drive coil 310 is located in the second region 360, and the housing 100 also includes a second heat dissipation state. The drive unit 300 is configured to control the drive coils 310 in the first region 350 and the second region 360 to alternately turn off and on in the second heat dissipation state, so as to achieve the flow effect of the magnetic fluid 240 in the first region 350 and the second region 360. Through the heat exchange of the flow of the magnetic fluid 240, the housing 100 can provide better heat dissipation for the functional modules of the mobile terminal and improve the working performance of the mobile terminal.

[0067] The second region 360 is adjacent to the first region 350. Both regions are equipped with drive coils 310. The sequential opening and closing of the drive coils 310 enables the flow of the magnetic fluid 240 within the first and second regions 350. During operation, the mobile terminal experiences temperature variations. The first region 350 can be positioned to correspond to the functional modules requiring the most heat dissipation, while at least a portion of the second region 360 can be offset from these functional modules. The flow of the magnetic fluid 240 within the first and second regions 350 further enhances heat dissipation for these modules.

[0068] Optionally, the housing 100 can maintain either the first heat dissipation state or the second heat dissipation state alone, or it can maintain both the first heat dissipation state and the second heat dissipation state simultaneously.

[0069] In some alternative embodiments, such as Figure 5 and Figure 8 As shown, the second region 360 includes a plurality of sub-regions 361 distributed sequentially in a direction away from the first region 350. Along the path from the second region 360 to the first region 350, the drive unit 300 is configured to control the drive coils 310 in each sub-region 361 to be turned off sequentially for a preset time period in a second heat dissipation state.

[0070] In these optional embodiments, the second region 360 includes a plurality of sub-regions 361 distributed sequentially in a direction away from the first region 350. Along the path from the second region 360 to the first region 350, the drive unit 300 is configured to control the drive coils 310 in each sub-region 361 to be turned off sequentially for a preset time period in a second heat dissipation state, thereby realizing the flow effect of the magnetic fluid 240 in the first region 350 and the second region 360, and through the flowing magnetic fluid 240, the housing 100 can provide better heat dissipation for the functional modules of the mobile terminal.

[0071] The second region 360 includes a plurality of sub-regions 361 distributed in a direction away from the first region 350, and each sub-region 361 is provided with at least one drive coil 310.

[0072] The drive unit 300 is configured to control the drive coils 310 in each sub-region 361 to be turned off sequentially for a preset time period in the second heat dissipation state. That is, one or more drive coils 310 in the first region 350 and / or the second region 360 form a sub-region 361. Except for the drive coils 310 in the sub-region 361 being turned off, the other drive coils 310 are turned on for a preset time period. After that, the sub-region 361 is replaced by one or more drive coils 310 along the extension direction of the second region 360 and one or more drive coils 310 adjacent to it. Except for the drive coils 310 in the sub-region 361 being turned off, the other drive coils 310 are turned on for a preset time period. This process is repeated to achieve the flow effect of the magnetofluid 240 in the first region 350 and the second region 360.

[0073] Alternatively, one or more drive coils 310 within the first region 350 and / or the second region 360 may form a sub-region 361. Except for the drive coil 310 in the sub-region 361 which is in the on state, all other drive coils 310 are in the off state. After the drive coil 310 in the sub-region 361 is turned on for a period of time, the drive coil 310 in the sub-region 361 is turned off. Then the sub-region 361 is replaced by one or more drive coils 310 adjacent to the one or more drive coils 310 in the extension direction of the second region 360. After the drive coil 310 in the sub-region 361 is turned on for a period of time, the drive coil 310 in the sub-region 361 is turned off, and this process is repeated to achieve the flow effect of the magnetofluid 240 in the first region 350 and the second region 360.

[0074] Optionally, multiple first regions 350 and second regions 360 can be set on the housing 100, and the number of first regions 350 and second regions 360 operating simultaneously can be set by the user.

[0075] In some alternative embodiments, such as Figure 5 and Figure 6 As shown, the housing 100 also includes a clearance area 400, which is located at least part of the edge of the light-transmitting panel 210 and is disposed on the side close to the drive unit 300. The drive unit 300 and the clearance area 400 are offset from each other, and the clearance area 400 is used to transmit electromagnetic waves.

[0076] In these embodiments, the housing 100 also includes a clearance area 400 located at at least a portion of the edge of the light-transmitting panel 210 and disposed on the side near the drive unit 300. The clearance area 400 and the drive unit 300 are offset to reduce the influence of the wiring layer 320, the first shielding layer 330 and the second shielding layer 340 on the mobile terminal antenna transmission and reception signals, thereby improving the reliability of the housing 100.

[0077] Optionally, the clearance area 400 is located at the edges on both sides of the light-transmitting panel 210 in the width direction, and / or the clearance area 400 is located at the edges on both sides of the light-transmitting panel 210 in the length direction.
