[0058] Figure 1 This is a structural schematic diagram of an embodiment of the display device of this utility model. Figure 2 This is a partial structural schematic diagram of the display device of this utility model. Figure 3 yes Figure 2 A schematic diagram of the structure from another perspective.

[0059] See Figures 1 to 3 This application provides a display device, including a housing 100, a display panel 200, and a far-field housing 300 disposed at the bottom of the housing 100. The display panel 200 is disposed on the front side of the housing 100 and is used to display image information for user viewing. A far-field module and / or a voice pickup module are housed within the far-field housing 300. The far-field housing 300 is capable of receiving sound signals emitted by the user and converting the sound into electrical signals for controlling the operation of the display device, thereby realizing voice interaction functionality.

[0060] In some embodiments, the far-field housing 300 can also be used to receive an external remote control for remote control of the operation of the display device.

[0061] In some embodiments, the housing 100 extends vertically and may include a back plate. The back plate is the main support for the display device, and the display device is disposed on the front side of the back plate. The back plate is a structure made of metal or plastic.

[0062] In other embodiments, the peripheral edge of the back panel forms a forward-protruding frame; the frame is circumferentially arranged and extends around the edge of the back panel. The frame extends forward beyond the front side of the back panel, and the frame and the back panel together form a mounting cavity with a front opening for mounting a light source and an optical film assembly. The display panel 200 is fixed to the front end of the frame.

[0063] The frame can be a middle frame that fixes the periphery of the back panel, the middle frame covering the edge of the back panel, and the middle frame surrounding the four periphery of the back panel. In some embodiments, the frame and the back panel are integrally formed, and the edge of the back panel extends forward to form the frame, which is circumferentially arranged.

[0064] In some embodiments, the display device may further include a light source (not shown) and an optical film assembly (not shown) disposed within the housing 100. The light source, the optical film assembly, and the display panel 200 are all fixed to the front side of the back panel. The light source, the optical film assembly, and the display panel 200 are arranged sequentially from back to front. Light emitted by the light source is projected onto the display panel 200 after passing through the optical film assembly, and image information is displayed on the display panel 200 after being processed by the display panel 200.

[0065] In some embodiments, the light source is an LED panel, which is attached to the bottom surface of the mounting cavity and emits white light towards the optical film assembly. In some embodiments, the backlight and the optical film assembly are spaced apart in the vertical direction to form a light mixing distance. In other embodiments, the backlight and the optical film assembly are attached together in the vertical direction.

[0066] An optical film assembly is positioned in front of and spaced from the backlight source to improve the uniformity and brightness of the light source. The optical film assembly includes a diffuser plate and multiple films arranged sequentially. The multiple films may include brightness enhancement plates and multiple prism sheets, or multiple films may include multiple prism sheets.

[0067] The display panel 200 is located in front of the optical film group. The light in the optical film group is transmitted forward to the display panel 200. The liquid crystal molecules in the display panel 200 are deflected by the electric field, which reduces the transmittance of the light emitted from the optical film group to the liquid crystal panel, thereby projecting the light into filters of different colors to form an image.

[0068] In some embodiments, the display device may include a lower front housing 400, which is disposed at the bottom of the housing 100 and the display panel 200 and extends in the left-right direction. After the lower front housing 400 is individually machined, it is fixed to the back plate, and the far-field housing 300 is fixed to the bottom surface of the lower front housing 400, so that the far-field housing 300 is mounted on the outside of the display device.

[0069] In one embodiment, the bottom edge of the back panel extends forward to form the lower front shell 400, which is integrally formed on the back panel.

[0070] In another embodiment, the bezel may include a top bezel, left and right edges, and a bottom bezel. The bottom bezel is configured to form the lower front shell 400.

[0071] In some embodiments, the display device may further include a rear cover that covers the back of the housing 100, and a cavity is formed between the front side of the rear cover and the back of the housing 100. A motherboard, a power board, and other driving components are disposed within this cavity. The motherboard, power board, and other driving components are located within the enclosure of the rear cover to protect the components within the cavity.

[0072] The motherboard is primarily used to perform calculations on the control system of the display device and output relevant operation commands. The motherboard contains numerous electronic components, mainly responsible for transmitting the operation commands output by the motherboard to the corresponding operating terminals. The power supply board is either separately mounted on the motherboard or integrated onto it, and is fixed to the back of the housing 100. Its main function is to provide the motherboard with drive voltage or a stable operating voltage, and to maintain a stable output current when the circuits on the motherboard are operating.

[0073] Other driving components include speakers and power strips. The speakers are located on the back of the housing 100 and are primarily used to produce corresponding sounds in conjunction with the interface displayed on the display panel 200. The power strip has multiple different types of interfaces for connecting external devices to receive or output signals to them.

[0074] In some embodiments, the power strip is integrated onto the motherboard. Other driving components may be structures such as a remote control module or a voice module.

[0075] Figure 4 This is a structural schematic diagram of the lower front shell of this utility model from one perspective. Figure 5 This is a structural schematic diagram of the lower front shell of this utility model from another perspective.

[0076] See Figures 2 to 5 The lower front cover 400 is disposed at the bottom of the housing 100 and the display panel 200, and the lower front cover 400 covers the bottom of the back panel and the display panel 200. The lower front cover 400 extends in the left and right direction, and the far-field housing 300 is fixed on the bottom surface of the lower front cover 400.

[0077] In one embodiment, the lower front shell 400 may be a structure made of a metallic material, such as aluminum alloy, steel, or iron.

[0078] In another embodiment, the lower front shell 400 may be a structure made of plastic material.

[0079] In some embodiments, a protrusion 410 may be provided on the lower front housing 400, the protrusion 410 being formed by protruding downward from the lower front housing 400. The upper surface of the lower front housing 400 protrudes downward to form the protrusion 410. The protrusion 410 extends downward beyond the bottom surface of the lower front housing 400 and can extend downward into the far-field housing 300.

[0080] In one specific embodiment, the protrusion 410 protrudes downward from the upper surface of the lower front housing 400, and a recess 420 is formed on the upper side of the protrusion 410 on the front housing, the recess 420 being lower than the upper surface of the lower front housing 400. The recess 420 is used to cooperate with a corresponding structure on the far-field housing 300 so that the corresponding structure on the far-field housing 300 does not protrude upward from the recess 420, thus avoiding interference with other components within the display device.

[0081] In some embodiments, one or more protrusions 410 are provided along the left-right direction. When multiple protrusions 410 are provided, the multiple protrusions 410 are spaced apart along the left-right direction.

[0082] In one embodiment, the bottom surface of the protrusion 410 is provided with a locking hole 411, which is used to engage with a corresponding structure on the far-field housing 300 to limit the far-field housing 300. The corresponding structure on the far-field housing 300 extends upward through the locking hole 411 and is limited on the protrusion 410.

[0083] In some embodiments, the card hole 411 extends vertically, with the upper end of the card hole 411 extending into the relief groove 420.

[0084] In other embodiments, the locator 411 can be a blind hole, with the upper end of the locator 411 closed.

[0085] In some embodiments, a groove 430 may be formed on the bottom surface of the lower front housing 400, and the groove 430 is recessed on the bottom surface of the lower front housing 400. The groove 430 extends rearward to the rear end of the lower front housing 400, so that the groove 430 has an upper sidewall, a front sidewall, and left and right sidewalls.

[0086] In one embodiment, a groove 430 is formed on the bottom surface of the lower front housing 400, and the upper end surface of the far-field housing 300 is fitted to the upper side surface of the groove 430. The upper end of the far-field housing 300 is accommodated in the groove 430, thereby making the far-field housing 300 have a smaller thickness in the vertical direction exposed below the display device.

[0087] In another embodiment, the bottom surface of the lower front shell 400 does not have a groove 430, and the far-field shell 300 is disposed below the lower front shell 400 and fits against the lower surface of the lower front shell 400.

[0088] In some embodiments, a limiting slot 450 is provided on the front sidewall of the groove 430, and a corresponding structure on the far-field housing 300 passes through the limiting slot 450 to limit the far-field housing 300.

[0089] In other embodiments, a guide groove 440 is provided on the bottom surface of the lower front shell 400. The guide groove 440 extends in the front-rear direction, and its front end extends to the limiting slot 450. The upper end of the limiting slot 450 is higher than the upper sidewall of the groove 430.

Figure 7 This is a structural schematic diagram of the far-field housing of this utility model from another perspective. Figure 8 A cross-sectional view of the buckle on the far-field housing of this utility model. Figure 9 This is a schematic diagram of the installation of the far-field housing of this utility model on the lower front shell. Figure 10 This is a cross-sectional view of a portion of the display device structure of this utility model.

[0091] See Figures 6 to 10 and combined Figures 2 to 5 In this application, the far-field housing 300 is disposed at the bottom of the lower front housing 400, and the far-field housing 300 is detachably mounted on the bottom surface of the lower front housing 400. The far-field housing 300 has a box-shaped structure, and the far-field housing 300 encloses an upper open receiving cavity 310. The far-field circuit board 500 is confined within the receiving cavity 310 for receiving external voice signals, thereby controlling the operation of the display device.

[0092] A pickup hole extending into the accommodating cavity is provided on the front side of the far-field housing to allow voice signals to pass through. A microphone is provided on the far-field circuit board 500 to receive voice signals.

[0093] In some embodiments, the far-field circuit board 500 on the far-field housing 300 is also equipped with a remote control module to work with a remote control. The far-field housing is provided with buttons, which can be used for functions such as power on / off.

[0094] The far-field housing 300 includes a bottom wall 311 and a circumferential wall 312 extending upward from the edge of the bottom wall 311; the circumferential wall 312 extends upward and surrounds the periphery of the bottom wall 311, and an accommodating cavity 310 with an open upper end is formed between the bottom wall 311 and the circumferential wall 312.

[0095] The far-field housing 300 is attached to the bottom surface of the lower housing 100. Specifically, the upper end of the far-field housing 300 is attached to the upper side wall of the groove 430, the front side of the far-field housing 300 is attached to the front side wall of the groove 430, and the rear side of the far-field housing 300 abuts against the rear cover, thus limiting the far-field housing 300 to the bottom of the display device.

[0096] In some embodiments, a forward-extending limiting tongue 320 is formed at the upper end of the front side of the far-field housing 300. The limiting tongue 320 can extend into and engage with the limiting slot 450 of the lower front housing 400 to restrict the downward movement of the front end of the far-field housing 300.

[0097] In other embodiments, the limiting tongue 320 protrudes from the upper end of the outer side of the circumferential wall 312. The limiting tongue 320 extends upward and then forward from the upper end of the far-field housing 300, so that the limiting tongue 320 is higher than the upper end of the far-field housing 300. A guide groove 440 is provided on the bottom surface of the lower front housing 400, and the limiting tongue 320 moves forward along the guide groove 440 and can extend into the limiting slot 450. The limiting tongue 320 is higher than the upper end of the far-field housing 300, which facilitates the observation of the movement of the limiting tongue 320 in the gap between the bottom surface of the lower front housing 400 and the upper end of the far-field housing 300 during the movement, thereby facilitating the installation of the far-field housing on the bottom surface of the lower front housing.

[0098] In some embodiments, the height of the limiting slot 450 in the vertical direction is greater than the thickness of the limiting tongue 320 in the vertical direction, so that after the limiting tongue 320 extends into the limiting slot 450, the limiting tongue 320 can be flipped upward within the limiting slot 450. After the limiting tongue 320 is inserted into the limiting slot 450, the far-field housing 300 can be flipped vertically relative to the lower front housing 400 around the limiting tongue 320, facilitating the fitting and installation of the far-field housing 300 on the lower front housing 400.

[0099] In some embodiments, the limiting slot 450 and the limiting tongue 320 are each configured as one.

[0100] In other embodiments, multiple limiting slots 450 are provided, and the multiple limiting slots 450 are spaced apart in the left-right direction; the number of limiting tongues 320 corresponds one-to-one with the number of limiting slots 450. For example, the number of limiting slots 450 is set to two, three, or four, etc.

[0101] In another embodiment, the limiting slot 450 is a groove extending in the left-right direction, and multiple limiting tongues 320 are provided, with the multiple limiting tongues 320 engaging in the same limiting slot 450.

[0102] See Figures 6 to 10A latch 330 protruding upwards is formed within the accommodating cavity 310. The latch 330 is elastically deformable in the horizontal direction to insert into and exit through a latch hole 411 on the lower front housing 400. The latch 330 is disposed within the latch hole 411 on the lower front housing 400, with its upper end overlapping the protrusion 410 downwards to restrict downward movement of the latch 330. The far-field housing 300 is fitted against the lower surface of the lower front housing 400 to restrict upward movement of the far-field housing 300 relative to the lower front housing 400, thereby restricting vertical movement of the far-field housing 300.

[0103] The latch 330 may include two extending ribs 331 and a latching protrusion 332. The two extending ribs 331 extend upward from the bottom surface of the receiving cavity 310. The two extending ribs 331 are arranged horizontally at intervals so that they can move closer to each other and further away from each other. Each extending rib 331 is provided with a latching protrusion 332, which is located on the opposite side of the upper end of the two extending ribs 331. The latching protrusion 332 can move closer to and further away from the two extending ribs 331, so that the latch 330 can undergo elastic deformation. The latching protrusion can undergo elastic deformation so that the latching hook can pass through the latching hole 411, facilitating the assembly and disassembly of the far-field housing 300 on the lower front housing 400.

[0104] In other embodiments, the snap fastener 330 may further include a snap cap 333, which is fixed to the upper ends of the two extension ribs 331. The snap cap 333 is connected to the upper ends of the two extension ribs 331 to maintain the stability and reliability of the structure of the two extension ribs 331. The outer peripheral surface of the snap cap 333 is a tapered surface that is smaller at the top and larger at the bottom. The tapered surface of the snap cap 333 extends to the free end of the snap protrusion 332 to guide the snap fastener 330 when it is inserted into the snap hole 411, making it easier to insert the snap fastener 330 into the snap hole 411.

[0105] In some embodiments, the upper end of the latch 330 does not extend beyond the upper surface of the lower front housing 400, thereby preventing interference between the upper end of the latch 330 and other components within the display device, thus protecting the display device. When the protrusion 410 protrudes downward from the lower front housing 400, and the latch 330 extends upward and engages with the protrusion 410, sufficient contact area between the protrusion 410 and the latch 330 in the vertical direction ensures that the upper end of the latch 330 does not extend beyond the upper surface of the lower front housing 400.

[0106] In one embodiment, the lower front housing 400 has a recessed groove 420 formed on the upper side of the protrusion 410; the upper end of the latch 330 extends into and is accommodated in the recessed groove 420, and overlaps the bottom wall 311 of the recessed groove 420. The latching cap 333 at the upper end of the latch 330 passes upward through the latching hole 411 on the protrusion 410 and is accommodated in the recessed groove 420, while the lower end of the latching protrusion 332 abuts against the bottom surface of the recessed groove 420. The latch 330 overlaps the bottom wall 311 of the recessed groove 420 to restrict the downward movement of the latch 330, thereby limiting the far-field housing 300 to the bottom of the lower front housing 400. The upper end of the latch 330 extending into and being accommodated in the recessed groove 420 ensures that the latch 330 will not interfere with other structures within the display device.

[0107] In one embodiment, the buckle 330 has a radially penetrating opening that extends vertically, thereby forming two horizontally spaced extending ribs 331 on the buckle 330.

[0108] In some embodiments, two extension ribs 331 are spaced apart in the front-rear direction, and the front and rear sides of the two extension ribs 331 respectively abut against the peripheral sidewall of the slot 411 to restrict movement in the front-rear direction, thereby restricting the movement of the far-field housing 300 in the front-rear direction.

[0109] In some embodiments, the latching protrusions 332 on the two extending ribs 331 include a front latching protrusion 3321 located at the front and a rear latching protrusion 3322 located at the rear; the rear side of the rear latching protrusion 3322 extends downward to the lower end of the rear latching protrusion 3322. When disassembling the far-field housing 300, the rear end of the far-field housing 300 is pressed downward. As the far-field housing 300 moves downward, the rear side of the rear latching protrusion 3322 is inclined forward in the downward direction for guidance, facilitating the installation of the far-field housing 300 on the lower front housing 400.

[0110] The rear end of the far-field housing 300 extends beyond the rear end of the lower front housing 400 to facilitate pressing the far-field housing 300 and to facilitate the disassembly of the far-field housing 300.

[0111] In other embodiments, the two extension ribs 331 are spaced apart in the left-right direction.

[0112] In some embodiments, two latches 330 are spaced apart in the left-right direction, and the two latches 330 are respectively disposed near the left and right ends of the far-field housing 300, so that the left and right ends of the far-field housing 300 are respectively attached to the far-field housing 300.

[0113] Based on the above structure, when installing the far-field housing 300, the far-field housing 300 is tilted upward and forward, and the limiting tongue 320 at the front end of the far-field housing 300 passes forward into the limiting slot 450. The rear end of the far-field housing 300 is flipped upward, and the buckle 330 on the far-field housing 300 moves upward and passes through the buckle hole 411. After the buckle 330 passes through the buckle hole 411, the upper end of the buckle 330 overlaps the bottom surface of the clearance groove 420, limiting the buckle 330 on the protrusion 410, and the far-field housing 300 is limited on the lower front housing 400.

[0114] When disassembling the far-field housing 300, pressing down on the rear end of the far-field housing 300 causes the rear end of the remote housing 100 to flip downward, thereby allowing the latch 330 to disengage from the latch hole 411 of the protrusion 410.
