Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a display device. Background Art

[0002] With the increasing adoption of smart TVs, far-field voice control has become an essential feature, enabling users to control their TVs through voice interaction without the need for a remote control or physical movement. For TVs with far-field voice control, the sound pickup module used to receive business signals typically combines remote control and power button functions and is secured within the far-field housing.

[0003] As television frames become increasingly narrower and thinner, the internal space thereof becomes increasingly smaller. Therefore, existing televisions tend to move the far-field housing to the outside of the television body to meet the requirements of existing narrow and thin frame designs.

[0004] In related technologies, to meet the requirements of remote control functionality, indicator lights, and production process routing, the far-field housing is typically placed near the front center of the lower portion of the TV. When viewed from the front, the far-field housing protrudes from the bottom edge of the TV, affecting the user experience. Currently, the lower front housing of a TV is often widened or thickened, with the far-field housing embedded within it to conceal it. However, this approach sacrifices the appearance of the lower front housing and increases material and production costs. Summary of the Invention

[0045] In related technologies, to meet the requirements of remote control functions, indicator lights, and production process routing, the far-field housing is generally placed in the front center of the lower part of the TV. When viewed from the front of the TV, the far-field housing protrudes from the lower edge of the TV, affecting the user experience. Currently, the lower front shell of a TV is often widened or thickened, and the far-field housing is embedded in the lower front shell to achieve a hidden function. However, this method sacrifices the appearance of the lower front shell and increases material and production costs. The present application provides a display device to solve the above technical problems.

[0046] For ease of description and understanding, the display device is used in a vertical position as a reference, the vertical direction is the up-down direction, the direction facing the user is the front, and the direction facing away from the user is the back. The width direction of the display device is the left-right direction.

[0047] Figure 1 2 is a schematic structural diagram of a display device embodiment of the present invention. Figure 2 yes Figure 1 A schematic structural diagram of the structure shown from one perspective. Figure 3 It is a schematic diagram of the exploded structure of an embodiment of the display device of the invention. Figure 4 It is a partial structural diagram of the display device of the present invention.

[0048] See Figures 1 to 4 This embodiment provides a display device comprising a display body 10 and a far-field assembly 20 disposed at the bottom of the display body 10. The front side of the display body 10 is used to display image information for viewing by the user. The far-field assembly 20 is used to receive audio signals generated by the user and convert the audio signals into electrical signals for controlling the operation of the display device. A remote control module is integrated into the far-field assembly 20 to enable remote control and voice control of the display device.

[0049] The display body 10 includes a back plate 110, a back cover 120 fixed to the back of the back plate 110, a display panel (not shown) fixed to the front of the back plate 110, a light source (not shown) disposed within the back plate 110, and an optical film assembly (not shown). The light source, the optical film assembly, and the display panel are arranged in sequence from back to front. Light emitted by the light source passes through the optical film assembly and is projected onto the display panel, where it is acted upon to display image information.

[0050] The light source is used to emit light. The light source and the optical film group are arranged in parallel. The light source is located on the light incident side behind the optical film group to emit light toward the optical film group. The optical film group is located in front of the backlight source so that after the light passes through the optical film group, uniform white light can be obtained on the light exit side in front of the optical film group.

[0051] The light source, the optical film assembly and the display panel are all fixed on the front side of the back plate 110 .

[0052] The back panel 110 is the primary support for the display device and is oriented vertically. A forward-projecting frame is formed around the perimeter of the back panel 110. This frame extends around the edge of the back panel 110. The frame extends forward beyond the front side of the back panel 110. Together, the frame and back panel 110 form a mounting cavity with an open front for mounting the backlight and optical film assembly. The display panel is secured to the front end of the frame.

[0053] The frame can be a middle frame that secures the edges of the back panel 110. The middle frame covers the edges of the back panel 110 and surrounds the edges of the back panel 110. In some embodiments, the frame and the back panel 110 are integrally formed, with the edges of the back panel 110 extending forward to form the frame, which is disposed around the circumference.

[0054] A lower front shell 130 extending in the left-right direction is disposed at the bottom of the back panel 110. The lower front shell 130 is fixed to the bottom end of the back panel 110. The lower front shell 130 is separately formed and fixed to the back panel 110. In other embodiments, the lower edge of the back panel 110 extends forward to form the lower front shell 130.

[0055] The backlight is an LED light panel, which is attached to the bottom surface of the mounting cavity and emits white light forward toward the optical film assembly. In some embodiments, a vertical gap exists between the backlight and the optical film assembly to form a light mixing distance. In other embodiments, the backlight and the optical film assembly are attached vertically.

[0056] The optical film assembly is positioned in front of the backlight, separated from the backlight by a gap, to improve the uniformity and brightness of the light source. The optical film assembly includes a diffuser plate and multiple films arranged in sequence. The multiple films may include a brightness enhancement film and multiple prism sheets, or multiple prism sheets.

[0057] The display panel is located in front of the optical film group. The light in the optical film group is transmitted forward to the display panel. The liquid crystal molecules in the display panel are deflected by the electric field stimulation, which reduces the transmission rate of the light emitted from the optical film group to the liquid crystal panel, and then projects the light into filters of different colors to form an image.

[0058] The back cover 120 covers the back of the back panel 110, forming a housing cavity between the front of the back cover 120 and the back of the back panel 110. The housing cavity houses the motherboard 140, power board, and other driver components. The motherboard 140, power board, and other driver components are located within the enclosure of the back cover 120, providing protection for the components within.

[0059] The mainboard 140 is mainly used to operate the control system of the display device and output relevant operation instructions accordingly. The mainboard 140 has a large number of electronic components, which mainly transmit the operation instructions output by the mainboard 140 to the corresponding operation terminal.

[0060] The power board is separately provided or integrated on the main board 140 and fixed on the back of the back plate 110. It is mainly used to provide driving voltage or stable working voltage to the main board 140 and keep the output current stable when the circuit on the main board 140 is working.

[0061] Other driving components include speakers and power strips. The speaker is located on the back of the back panel 110 and is primarily used to produce sounds corresponding to the interface displayed on the display panel. The power strip is equipped with multiple different types of interfaces for connecting to external devices, receiving signals from external devices or outputting signals to external devices. In some embodiments, the power strip is integrated into the mainboard 140. Other driving components may include structures such as a remote control module or a voice module.

[0062] The display body 10 is further provided with a base 150 , which is fixed to the back plate 110 or the back cover 120 . The lower end of the base 150 extends beyond the display body 10 to support the display body 10 .

[0063] Part of the structure of the display device refers to the corresponding structure of the display device in the related art and will not be described in detail here.

[0064] Figure 5 It is a structural schematic diagram of the lower front shell of the present invention from one perspective. Figure 6 It is a structural schematic diagram of the lower front shell of the present invention from another perspective.

[0065] See Figures 1 to 6 The lower front housing 130 extends in the left-right direction and has a rearward-extending extension wall 131 formed thereon. The far-field assembly 20 is secured to the extension wall 131. The extension wall 131 is located below the display panel and the back panel 110. The lower front housing 130 is secured to the bottom of the back panel 110 to position the bottom of the display panel; the lower front housing 130 shields the bottom of the back panel 110 and the display panel.

[0066] A retaining groove 132 is defined on the bottom surface of the lower front housing 130. Specifically, the bottom surface of the extension wall 131 defines a retaining groove 132 for engaging with the far-field assembly 20 and securing the far-field assembly 20 to the lower front housing 130. The rear end of the retaining groove 132 extends through the rear end of the extension wall 131, and the front end of the retaining groove 132 is closed.

[0067] In this embodiment, the limiting groove 132 is formed in the middle of the lower front shell 130 in the left-right direction. In some embodiments, the limiting groove 132 is eccentrically disposed in the left-right direction of the lower front shell 130.

[0068] A connection hole 133 is formed on the bottom wall of the retaining groove 132. The connection hole 133 is used to cooperate with the far-field assembly 20 to fix the far-field assembly 20 to the lower front housing 130. The connection hole 133 is a threaded hole so that a fastener can pass through the far-field assembly 20 and the connection hole 133.

[0069] There are one or more connection holes 133. In this embodiment, two connection holes 133 are spaced apart in the left-right direction.

[0070] The bottom rear end of the extension wall 131 of the lower front shell 130 is further provided with a relief groove 134. The relief groove 134 is provided on the rear end of the bottom surface of the extension wall 131. The relief groove 134 is closed along the front end and open at the rear end. The relief groove 134 extends in the left-right direction.

[0071] A fastening hole 135 and a limiting card hole 136 are defined on the bottom surface of the extension wall 131 of the lower front shell 130 . The fastening hole 135 and the limiting card hole 136 are located on the bottom wall above the avoidance groove 134 to fix and limit the rear cover 120 .

[0072] Figure 7 It is a structural schematic diagram of the back cover of the present invention from one viewing angle. Figure 8 It is a structural schematic diagram of the back cover of the present invention from another perspective. Figure 9 yes Figure 8 Enlarged view of point A in the middle. Figure 10 yes Figure 8 Enlarged view of point B in the middle.

[0073] See Figures 2 to 10 The back cover 120 covers the back of the back panel 110. The back cover 120 includes a cover plate 121 and an extension plate 122 extending forward from the bottom end of the cover plate 121. The cover plate 121 covers the back of the back panel 110. A receiving cavity is formed between the front side of the cover plate 121 and the back of the back panel 110, forming a receiving cavity between the back of the back panel 110 and the back cover 120. The mainboard 140 is accommodated in this receiving cavity.

[0074] The front end of the extension plate 122 extends forward and abuts the lower front shell 130. The upper surface of the front end of the extension plate 122 fits within the avoidance groove 134 on the lower front shell 130. At least part of the front end of the extension plate 122 is accommodated within the avoidance groove 134, thereby concealing the extension plate 122 from the lower front shell 130 and maintaining a seal between the front end of the extension plate 122 and the lower front shell 130.

[0075] The extension plate 122 and the extension wall 131 of the lower front shell 130 are connected by a structure such as a snap-fit ​​or fastener, and the extension plate 122 and the lower front shell 130 are fixed by corresponding snap-fit ​​structures or screw holes between the extension plate 122 and the lower front shell 130.

[0076] In this embodiment, a through hole (not shown) is formed in the extension plate 122. The through hole aligns with the fastening hole 135 on the lower front shell 130, allowing fasteners to pass through the corresponding through hole and fastening hole 135 to secure the extension plate 122 to the extension wall 131. The fastening hole 135 is a threaded hole, and the fastener is a structural member such as a bolt or screw. A limiting protrusion 123 is provided at the front end of the upper surface of the extension plate 122. The limiting protrusion 123 is configured to extend into and engage with a limiting locking hole 136 on the lower front shell 130. The rear end of the limiting protrusion 123 overlaps the rear side wall of the limiting locking hole 136, limiting the rearward movement of the extension plate 122.

[0077] The extension plate 122 has wire grooves on either side of the limiting protrusion 123. The wire grooves extend vertically through the extension plate 122, and their front ends extend to the front end of the lower front housing 130. This allows the portion of the extension plate 122 where the limiting protrusion 123 is located to be elastic and deform, facilitating the engagement of the limiting protrusion 123 within the limiting locking hole 136. The front side surface of the limiting protrusion 123 is a rearwardly inclined surface in the downward-upward direction, which serves as a guide, facilitating the movement of the limiting protrusion 123 from the rear end of the extension wall 131 to the limiting locking hole 136.

[0078] A limit slot 124 is provided at the front end of the upper surface of the extension plate 122. The limit slot 124 engages with the rear edge of the extension wall 131 to limit the vertical movement between the extension plate 122 and the extension wall 131, thereby maintaining the extension plate 122 in contact with the avoidance slot 134 on the bottom surface of the extension wall 131. In this embodiment, a protruding limit latch is provided on the upper surface of the extension plate 122. The limit latch extends upward and then forward, thereby enclosing the limit slot 124 between the limit latch and the upper surface of the extension plate 122.

[0079] Figure 11 It is a schematic diagram of the connection between the rear cover and the lower front shell of the present invention.

[0080] See Figures 2 to 11 The extension plate 122 is provided with an accommodating opening 125 extending vertically therethrough for limiting and accommodating the far-field component 20 . The accommodating opening 125 is located below the accommodating cavity between the rear cover 120 and the back plate 110 and communicates with the accommodating cavity.

[0081] In this embodiment, the accommodating opening 125 extends forward through the front end of the extension plate 122 , and the front end of the accommodating opening 125 is connected to the rear end of the limiting groove 132 , so that the far-field component 20 is limited between the limiting groove 132 and the accommodating opening 125 along the front-to-back direction.

[0082] A front-open positioning slot 126 is formed on the front side of the cover plate 121 or the top surface of the extension plate 122. The positioning slot 126 is used to engage the far-field limiting assembly 20. In this embodiment, a protruding positioning projection is formed on the top surface of the extension plate 122 behind the accommodating opening 125. The positioning projection extends upward and then forward, forming the positioning slot 126 between the positioning projection and the top surface of the extension plate 122.

[0083] In this embodiment, the extension plate 122 extends downward from the rear of the receiving opening 125 to form a retaining rib 127. The rear end of the retaining rib 127 is integrally connected to the rear cover 120. The retaining rib 127 includes a horizontal section and connecting sections extending upward from both ends of the horizontal section. The upper ends of the connecting sections are integrally connected to the extension plate 122. A positioning protrusion is provided on the retaining rib 127.

[0085] See Figures 2 to 17 The far-field assembly 20 includes a far-field housing 200 and a pickup module disposed within the far-field housing 200. The far-field housing 200 is fixed to the bottom end of the lower front shell 130 and / or the bottom end of the rear cover 120. The pickup module is disposed in the space above the far-field housing 200.

[0086] It should be noted that in this embodiment, the sound pickup module is integrated on the mainboard 140, and the far-field housing 200 is located below the mainboard 140. In some embodiments, the sound pickup module is provided separately, and the sound pickup module and the mainboard 140 are two structural components. The sound pickup module is separately fixed in the far-field housing 200 and is located above the far-field housing 200.

[0087] In one embodiment:

[0088] The far-field housing 200 is positioned within the receiving opening 125 of the rear cover 120 and is disposed adjacent to the cover plate 121 such that the far-field housing 200 is located behind the lower front housing 130. The far-field housing 200 extends downward beyond the bottom end of the lower front housing 130 and the bottom end of the extension plate 122. A sound pickup hole 201 is defined in the far-field housing 200 and is located below the lower front housing 130 and the extension plate 122. The sound pickup module is located above the far-field housing 200 and is at least partially located within the far-field housing 200.

[0089] The sound pickup hole 201 is located below the lower front shell 130 and the extension plate 122. The lower front shell 130 and the rear cover 120 do not block the front side of the sound pickup, thereby effectively ensuring that sound can be transmitted from the front side to the rear side to the sound pickup module in the far-field housing 200, enabling interaction with the user. The far-field housing 200 is constrained within the receiving opening 125 of the rear cover 120 and is positioned near the cover plate 121, so that the far-field housing 200 is located behind the lower front shell 130. When viewing the display device from the center of the front side of the display device, when the user's line of sight looks down and back to the bottom edge of the lower front shell 130, the bottom edge of the lower front shell 130 blocks the user's line of sight, effectively preventing the user from observing the far-field housing 200 and improving the user experience.

[0090] The far-field housing 200 includes a vertically arranged front panel 210, a bottom panel 220 extending rearward from the lower end of the front panel 210, and side panels 230 disposed on the left and right sides of the front panel 210. The side panels 230 are connected to the corresponding left and right sides of the front panel 210 and bottom panel 220. The front panel 210 and side panels 230 extend upward into and engage with the accommodating opening 125, thereby retaining the far-field housing 200 within the accommodating opening 125.

[0091] The sound pickup hole 201 is formed on the front plate 210 and passes through the front plate 210 in the front-to-back direction, so that the sound can be directly transmitted backwards into the sound pickup hole 201 .

[0092] In this embodiment, the far-field housing 200 further includes an extension plate 240 extending forward from the upper end of the front plate 210. The extension plate 240 extends horizontally forward. The extension plate 240 is fixed or limited to the bottom of the lower front shell 130 so that the far-field housing 200 is limited to the bottom of the lower front shell 130 and the rear cover 120.

[0093] In some embodiments, the far-field housing 200 is not provided with an extension plate 240. The far-field housing 200 is completely positioned within the front-to-back range of the rear cover 120 in the front-to-back direction. The far-field housing 200 is fixed to the rear cover 120 using fasteners and snap-fit ​​methods. When the extension plate 240 is not provided, the retaining groove 132 is not required on the lower front housing 130.

[0094] In this embodiment, an extension plate 240 is provided on the far-field housing 200. The front end of the extension plate 240 is attached to and fixed in the limiting groove 132. The front end of the limiting groove 132 is closed and the rear end is open, thereby ensuring that at least a portion of the extension plate 240 is accommodated in the limiting groove 132, so that the extension plate 240 can be fully broken by the bottom edge of the limiting groove 132, effectively preventing the user from observing the extension plate 240.

[0095] In this embodiment, the far-field assembly 20 includes a far-field housing 200 and a sound pickup module disposed within the far-field housing 200. The front housing extends downward from the rear end of the extension plate 240, and a sound pickup hole 201 is defined in the front plate 210 or the bottom plate 220. This ensures that the sound pickup hole 201 is lower than the lower front housing 130, preventing the lower front housing 130 from blocking the front side of the sound pickup. This effectively ensures that sound can be transmitted from the front to the rear to the sound pickup module within the far-field housing 200, enabling user interaction. This ensures that voice interaction with the far-field assembly 200 is not affected when the far-field housing 200 is within a blind spot.

[0096] The far-field housing 200 is limited in the accommodating opening 125 and is arranged close to the cover plate 121, so that the far-field housing 200 is located behind the lower front housing 130, and the front end of the front plate 210 and the lower front housing 130 have a preset distance, so that when a user views the display device at the front center of the display device, after the user's line of sight looks downward and backward to the bottom edge of the lower front housing 130, the bottom edge of the lower front housing 130 blocks the user's line of sight, and there is a blind spot at the lower ends of the lower front housing 130 and the rear cover 120. The far-field housing 200 is located in the blind spot, which effectively prevents the user from observing the far-field housing 200, thereby improving the user experience.

[0097] In another embodiment:

[0098] The bottom surface of the lower front shell 130 is provided with a limiting slot 132; the front end of the limiting slot 132 is closed and the rear end is open. The far-field assembly 20 includes a far-field housing 200 and a pickup module disposed within the far-field housing 200; the far-field housing 200 includes an extension plate 240 extending in a front-to-back direction, a front plate 210 extending downward from the rear end of the extension plate 240, and a bottom plate 220 extending rearward from the lower end of the front plate 210; the front end of the extension plate 240 is affixed and fixed within the limiting slot 132; the front plate 210 is adjacent to the back of the rear cover 120 and is spaced apart from the rear cover 120; the pickup module is disposed between the rear side of the front plate 210 and the rear cover 120; a pickup hole 201 is provided on the front plate 210 or the bottom plate 220, and the pickup hole 201 is lower than the lower front shell 130.

[0099] In this embodiment, the front end of the extension plate 240 is attached to and fixed in the limiting groove 132 of the lower front shell 130, the front plate 210 extends toward each other from the rear end of the lower front shell 130, and the front plate 210 approaches the back of the rear cover 120, so that there is a preset distance between the front end of the front plate 210 and the lower front shell 130, so that when the user views the display device at the front center of the display device, after the user's line of sight looks downward and backward to the bottom edge of the lower front shell 130, the bottom edge of the lower front shell 130 blocks the user's line of sight, and there is a blind spot at the lower ends of the lower front shell 130 and the rear cover 120. The far-field shell 200 is located in the blind spot, which effectively prevents the user from observing the far-field shell 200, thereby improving the user experience. A limiting groove 132 is provided on the bottom surface of the lower front shell 130; the front end of the limiting groove 132 is closed and the rear end is open; the front end of the extension plate 240 is attached to and fixed in the limiting groove 132, and the lower front shell 130 blocks the user's downward and rearward vision, effectively preventing the user from observing the front end of the extension plate 240 from the front side of the display device, thereby playing the role of shielding the far-field shell 200.

[0100] It should be noted that, in a specific embodiment, the extension plate 240 is limited on the bottom plate 220 , the front plate 210 is located at the rear end of the extension plate 240 , and the other parts of the rear cover 120 except the extension plate 240 do not need to be fixed to the rear cover 120 .

[0101] In this embodiment, the far-field assembly 20 includes a far-field housing 200 and a sound pickup module disposed within the far-field housing 200. The far-field housing 200 includes an extension plate 240 extending in a front-to-back direction, a front plate 210 extending downward from the rear end of the extension plate 240, and a bottom plate 220 extending rearward from the lower end of the front plate 210. The front housing extends downward from the rear end of the extension plate 240. Sound pickup holes are defined in the front plate 210 or the bottom plate 220. These holes are positioned lower than the lower front housing 130, ensuring that the lower front housing 130 does not block the front side of the sound pickup. This effectively ensures that sound can be transmitted from the front to the sound pickup module within the far-field housing 200, enabling user interaction.

[0102] See again Figures 2 to 17 In this application, a through hole 250 is formed on the front panel 210 and extends vertically therethrough. A connecting hole 133 is formed on the bottom wall of the retaining groove 132, corresponding to the through hole 250. Fasteners are used to connect the through hole 250 and the connecting hole 133, thereby securing the front panel 210 to the extension wall 131 of the lower front housing 130. In some embodiments, the front panel 210 and the lower front housing 130 are secured by structures such as buckles and hooks.

[0103] The far-field housing 200 also includes reinforcing ribs 260, which are located on the bottom surface of the extension plate 240 and extend in the front-to-back direction. The provision of the reinforcing ribs 260 enhances the structural strength of the extension plate 240. The rear end of the reinforcing ribs 260 is connected to the front plate 210. Two reinforcing ribs 260 are spaced apart in the left-right direction, one on each of the left and right edges of the extension plate 240 and the other on the left and right edges of the front plate 210.

[0104] The bottom edge of the reinforcing rib 260 is tilted downward from the front to the back, and the front end of the bottom edge of the reinforcing rib 260 coincides with the front end edge of the extension plate 240, effectively preventing the reinforcing rib 260 from being observed by the user's backward and downward vision.

[0105] In this embodiment, the far-field housing 200 further includes a rear plate 270 and a retaining plate 280 extending rearward from the upper end of the rear plate 270. The retaining plate 280 engages rearwardly within the positioning slot 126 to restrict the vertical movement of the retaining plate 280. The lower edge of the rear plate 270 abuts against the limiting rib 127.

[0106] The upper ends of the rear panel 270 and the card panel 280 are lower than the front panel 210 and the side panel 230, so that the upper side of the rear end of the far-field housing 200 is open, thereby allowing more space between the rear side of the front panel 210 of the far-field housing 200, so that there is enough space between the back side of the front panel 210 and the rear cover 120 to control the pickup module, so that the front shell is moved closer to the cover plate 121 and the far-field housing 200 is more effectively hidden.

[0107] In this embodiment, a positioning boss 202 is provided on the back of the front plate 210 for limiting the position of the sound pickup module. A fixing hole 203 is provided on the back of the front plate 210 for fixing the sound pickup module.
