Abstract

This application relates to the field of display technology, and more particularly to a display device. The display device of this application includes a display panel, a back panel, a rear shell, a radio module, and a mounting bracket. By detachably connecting the mounting bracket to the back panel, and having a first through hole on the mounting bracket, a first fastener on the rear shell passes through the first through hole and directly engages with a first snap-fit ​​hole on the back panel. This achieves one-time assembly and positioning of the mounting bracket, rear shell, and back panel, simplifying the assembly steps, reducing assembly errors caused by multiple assemblies, and improving the installation efficiency and effect of the display device.

Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display device. Background Technology

[0002] As display devices become more widely used, their functions are also becoming more diverse. Taking television as an example, smart TVs with voice recognition capabilities have become a trend, and the voice recognition function relies on a radio module installed inside the television.

[0003] In related technologies, the radio module needs to be mounted on the back panel using a mounting bracket, and the rear shell needs to be assembled with the mounting bracket and the back panel separately to fix the mounting bracket on the rear shell, the rear shell on the back panel, and the mounting bracket on the back panel. Since this installation method requires multiple installation and positioning, it will lead to multiple assembly errors between the rear shell, the mounting bracket, and the back panel, thereby affecting the installation efficiency and installation effect of the display device. Utility Model Content

[0004] This application discloses a display device that can reduce assembly errors caused by multiple assembly steps and improve the installation efficiency and effect of the display device by enabling screwless installation.

[0005] In some embodiments of this application, the display device includes:

[0006] Display panel, the display panel being used to display images;

[0007] A back plate, which supports the display panel;

[0008] A rear shell is connected to the back plate on the side opposite to the display panel, and a mounting cavity is formed between the rear shell and the back plate, the mounting cavity having an opening communicating with the outside of the display device;

[0009] A microphone module is used to acquire voice signals. The microphone module is disposed in the mounting cavity and has a first microphone hole, which is set to correspond to the opening of the mounting cavity.

[0010] The mounting bracket is disposed within the mounting cavity to support the radio module, and the mounting bracket is detachably connected to the back plate;

[0011] The back panel is provided with a first snap hole, the rear shell is provided with a first buckle, and the mounting bracket is provided with a first through hole communicating with the first snap hole. The first buckle passes through the first through hole and fastens to the first snap hole, so that the mounting bracket is clamped between the rear shell and the back panel.

[0012] On the one hand, by detachably connecting the mounting bracket to the back panel, and having a first through hole on the mounting bracket, the first buckle on the back cover passes through the first through hole and directly engages with the first snap hole on the back panel, thereby achieving one-time assembly and positioning between the mounting bracket, the back cover, and the back panel. This simplifies the assembly steps, reduces assembly errors caused by multiple assemblies, and improves the installation efficiency and effect of the display device.

[0013] On the other hand, by using the first buckle on the back cover to pass through the first through hole of the mounting bracket and directly engage with the first snap hole on the back plate, it can effectively save the stacking space between structures, thereby achieving further thinning of the display device and facilitating the realization of a lightweight and thin design for the display device.

[0014] Meanwhile, since the mounting bracket is detachably connected to the back panel, it also facilitates the disassembly, repair, and replacement of the radio module, thereby improving the ease of maintenance of the display device.

[0015] Furthermore, compared to the screw-connected mounting method where the mounting bracket is attached to the backplate, the mounting bracket is connected to the backplate via clips. This connection method eliminates the need for screws or other fasteners, avoids drilling threaded holes in the backplate, maintains the integrity of the backplate, and improves its structural strength. In addition, the clip-on connection reduces the use of tools and assembly time during the assembly process, which helps to reduce assembly costs.

[0016] In some embodiments of this application, the mounting bracket is further provided with a second through hole, and the rear shell is further provided with a first limiting part, which passes through the second through hole to limit the position of the mounting bracket relative to the rear shell.

[0017] By setting the first limiting part through the second through hole, the rear shell can be initially positioned when it is installed on the back plate, which facilitates subsequent installation operations; it can also restrict the movement of the mounting bracket in the direction parallel to the surface of the rear shell, thereby limiting the mounting bracket on the rear shell and further improving the stability of the assembly between the mounting bracket, the rear shell and the back plate.

[0018] In some embodiments of this application, the first buckle is provided with a reinforcing part, and the reinforcing part has a clearance position for avoiding the mounting bracket.

[0019] Because the first fastener needs to extend from the rear shell and pass through the entire mounting bracket before engaging with the first locking hole on the back plate, its extension length is relatively long. Therefore, by providing a reinforcing part on the first fastener, the structural strength of the first fastener can be effectively improved, preventing breakage or deformation during assembly. This ensures that the first fastener can smoothly engage with the first locking hole, guaranteeing the stability of the assembly between the mounting bracket, rear shell, and back plate.

[0020] In addition, the clearance on the reinforcing part is used to avoid interference between the reinforcing part and the mounting bracket, thereby ensuring that the first fastening part can smoothly pass through the first through hole of the mounting bracket and engage with the first snap hole.

[0021] In some embodiments of this application, the back plate is provided with a first hook and a first insertion hole;

[0022] The mounting bracket is equipped with:

[0023] A limiting tongue is provided on the edge of the mounting bracket and inserted into the first socket;

[0024] A snap-fit ​​structure is provided on the mounting bracket, and the snap-fit ​​structure is engaged with the first hook so that the mounting bracket can be detachably connected to the back plate.

[0025] A limiting tongue located at the edge of the mounting bracket inserts into a first socket on the backplate. The engagement of the limiting tongue and the first socket provides initial positioning of the mounting bracket on the backplate. Furthermore, based on this initial positioning, the mounting bracket also features a snap-fit ​​structure that engages with a first hook on the backplate, enabling a detachable connection between the mounting bracket and the backplate. This connection method is not only simple and easy to implement, but also effectively reduces assembly resistance between the mounting bracket and the backplate, improving installation efficiency and effectiveness.

[0026] In some embodiments of this application, the backplate includes:

[0027] Main body;

[0028] A protrusion is provided on the side of the main body away from the display panel, and the protrusion is provided with the first insertion hole and the first hook;

[0029] The mounting bracket includes:

[0030] The first part is fitted to the main body to form a receiving cavity between the first part and the main body, the microphone module is housed in the receiving cavity, and the microphone module is detachably connected to the first part;

[0031] The second part is connected to the first part, and the second part is correspondingly provided to the protrusion to be connected to the protrusion. The second part is provided with the limiting tongue and the buckle structure.

[0032] By setting the first part of the mounting bracket to mate with the main body to form a cavity for accommodating the radio module, and the second part corresponding to the protrusion on the back panel, the limiting tongue and snap-fit ​​structure on the second part can be closer to the first insertion hole and first hook on the protrusion. This avoids the need for excessively long limiting tongues and snap-fit ​​structures, thus facilitating assembly while reducing the overall size of the mounting bracket. Furthermore, the overall strength of the limiting tongue and snap-fit ​​structure is also higher, making them less prone to breakage or deformation. Simultaneously, since the mounting bracket is located on the upper edge of the back panel, and the protrusion protrudes from the side of the main body away from the display panel, the first part, while mates with the main body, can also abut against the protrusion. This allows the protrusion to provide upward support to the first part, ensuring that the first microphone hole of the radio module is as close as possible to the opening of the mounting cavity, thereby improving the radio module's reception performance.

[0033] In some embodiments of this application, the radio module includes:

[0034] A pickup element, wherein the pickup element is provided with the first sound receiving hole, and the pickup element is engaged with the first part;

[0035] A connecting wire, one end of which is connected to the pickup element;

[0036] The second part is provided with a groove communicating with the accommodating cavity, and the other end of the connecting wire extends out from the groove.

[0037] As can be seen, the connection between the microphone and the first part also adopts a snap-fit ​​connection. This snap-fit ​​connection method facilitates the disassembly, repair, or replacement of the microphone module by maintenance personnel, improving the maintainability of the display device. Furthermore, one end of the connecting cable is connected to the microphone to transmit the sound signal collected by the microphone to the display device. The second part is provided with a cable tray communicating with the accommodating cavity. The cable tray is used to collect the connecting cable, and the other end of the connecting cable extends from the cable tray so that the other end of the connecting cable can extend from the mounting bracket and connect to the motherboard of the display device, thereby achieving effective power connection for the microphone.

[0038] In some embodiments of this application, the limiting tongue is disposed on the edge of the mounting bracket along a first direction;

[0039] Multiple buckle structures are provided, and the multiple buckle structures are spaced apart along the second direction. The limiting tongue is located between two adjacent buckle structures.

[0040] The second direction intersects with the first direction.

[0041] By placing the limiting tongue between two adjacent snap-fit ​​structures and positioning it along the edge of the mounting bracket in the first direction, a three-point positioning structure is formed between the two snap-fit ​​structures and the limiting tongue. This three-point positioning structure further improves the positioning accuracy of the mounting bracket on the backplate and enhances the stability of the connection between the mounting bracket and the backplate. Simultaneously, because the limiting tongue and snap-fit ​​structures are positioned at different locations on the mounting bracket, the connection between the mounting bracket and the backplate is more reliable and less prone to loosening or detachment.

[0042] In some embodiments of this application, the snap-fit ​​structure includes:

[0043] A first extension extends from the mounting bracket toward the back plate;

[0044] The second extension has one end bent and connected to the first extension, and extends from the back plate toward the mounting bracket. The other end of the second extension is suspended. The second extension is provided with a second buckle, which is used to engage with the first hook.

[0045] A gap is formed between the first extension and the second extension, the gap being configured to provide space for the second extension to move when the second extension is subjected to force, so as to cause the second buckle to disengage from the first hook.

[0046] By designing the specific structure of the snap-fit ​​mechanism, a gap is created between the first and second extensions. This design not only enhances the flexibility of the snap-fit ​​structure but also ensures that it can smoothly disengage from the first hook under force, facilitating the disassembly of the mounting bracket. Specifically, when the mounting bracket needs to be disassembled, external force can be applied to the second extension, utilizing the gap to provide movement space for the second extension. This allows the second extension to pull the second latch out of the first hook without damaging the snap-fit ​​structure or the back panel, thus maintaining the structural integrity of the display device. Furthermore, since the movement space of the second extension is provided by the gap between the first and second extensions, the disengagement of the second latch on the second extension only requires the space within the mounting bracket itself, without the back panel needing to provide additional movement space for the mounting bracket. This effectively improves the space utilization of the back panel, thereby increasing the space utilization of the display device.

[0047] In some embodiments of this application, the back plate is further provided with a third through hole, and the mounting bracket is provided with a second limiting part, which passes through the third through hole to restrict the movement of the mounting bracket in a direction parallel to the surface of the back plate.

[0048] By setting a second limiting part through the second through hole, the movement of the mounting bracket in a direction parallel to the surface of the back plate is restricted, thereby effectively improving the stable installation of the mounting bracket on the back plate and further improving the installation effect of the mounting bracket on the back plate.

[0049] In some embodiments of this application, the backplate includes:

[0050] Top edge;

[0051] The lower edge, the upper edge and the lower edge are arranged opposite each other along the height direction of the display panel;

[0052] Two side edges are arranged opposite each other along the width direction of the display panel, and the upper edge, the lower edge, and the two side edges are connected to enclose each other;

[0053] The mounting bracket is located at the upper edge.

[0054] Since the speakers of display devices are typically located at the bottom or side, placing the microphone module on the top of the display device accordingly avoids the sound emitted by the speakers being received by the microphone module, preventing echoes or sound confusion, thereby improving the accuracy of the microphone module's speech recognition. Furthermore, since display devices are usually placed on a table or mounted on a wall, and the user is typically positioned in front of the display panel, placing the microphone module on the top of the display device, with the first microphone hole closer to the user's speaking direction, results in better sound pickup. It also effectively prevents the microphone module from being blocked by other objects on the table when the display device is placed on it, ensuring the clarity of the sound signal received by the microphone module.

[0055] Compared with the prior art, the beneficial effects of this application are:

[0056] The display device disclosed in this application includes a display panel, a back plate, a rear shell, a microphone module, and a mounting bracket. The display panel is used to display images, the back plate is used to support the display panel, and the rear shell is connected to the side of the back plate away from the display panel. A mounting cavity is formed between the rear shell and the back plate, and the mounting cavity has an opening communicating with the outside of the display device. The microphone module is used to acquire voice signals and is disposed within the mounting cavity. The microphone module has a first microphone hole, which is disposed corresponding to the opening of the mounting cavity. The mounting bracket is disposed within the mounting cavity to support the microphone module and is detachably connected to the back plate.

[0057] On the one hand, by detachably connecting the mounting bracket to the back panel, and with the mounting bracket having a first through hole, the first fastener on the rear shell passes through the first through hole and directly engages with the first snap-fit ​​hole on the back panel. This achieves one-time assembly and positioning of the mounting bracket, rear shell, and back panel, simplifying the assembly steps, reducing assembly errors caused by multiple assemblies, and improving the installation efficiency and effect of the display device. On the other hand, by utilizing the first fastener on the rear shell to pass through the first through hole of the mounting bracket and directly engage with the first snap-fit ​​hole on the back panel, it is also possible to effectively save stacking space between structures, thereby achieving further thinning of the display device and facilitating the realization of a lightweight and thin design for the display device.

[0058] Furthermore, since the mounting bracket is detachably connected to the back panel, it facilitates the disassembly, repair, and replacement of the radio module, thereby improving the ease of maintenance of the display device. Moreover, compared to the screw connection between the mounting bracket and the back panel, the mounting bracket is connected to the back panel via clips. This connection method eliminates the need for screws or other fasteners, avoiding the need for threaded holes in the back panel, maintaining its integrity, and improving its structural strength. In addition, the clip connection reduces the use of tools and assembly time during the assembly process, thus helping to lower assembly costs. Attached Figure Description

[0084] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0085] In this application, the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0086] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0087] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0088] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0089] In the description of this application, it should be noted that the singular forms of "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that terms such as "comprising / including" or "having" specify the presence of the stated features, integrals, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integrals, steps, operations, components, parts, or combinations thereof.

[0090] As display devices are used more and more widely, their functions are also showing a trend of diversification. Taking televisions as an example, smart TVs with voice recognition capabilities have become a trendsetter in the industry. This function relies on a radio module installed inside the television, which can capture the user's voice commands, thereby enabling convenient intelligent interaction.

[0091] In related technologies, the installation of the radio module typically requires a mounting bracket to secure it to the back panel of the television. The television's rear casing then needs to be assembled separately with both the mounting bracket and the back panel to ensure a secure fixation between them. However, this installation method requires multiple separate installation and positioning steps, which is cumbersome and time-consuming. Furthermore, multiple assembly steps can easily introduce assembly errors, which may gradually appear during subsequent use, affecting the overall installation efficiency and final installation effect of the display device, thus negatively impacting product quality and user experience.

[0092] In view of this, the display device disclosed in this application can achieve one-time assembly and positioning of the mounting bracket, rear shell, and back panel. This not only simplifies the assembly process and reduces assembly errors caused by multiple assemblies, but also improves the installation efficiency and effect of the display device. Furthermore, since the mounting bracket is detachably connected to the back panel, it facilitates the disassembly, repair, and replacement of the radio module, thus improving the maintenance convenience of the display device. Moreover, compared to screw-connected installation methods, the mounting bracket is connected to the back panel via clips, further enhancing the installation efficiency and convenience of the display device.

[0093] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0094] Please refer to the following: Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the display device provided in the embodiments of this application. Figure 2 This is an exploded view of the display device provided in the embodiments of this application. Figure 3This is a front view of a display device provided in an embodiment of this application. This application discloses a display device 100, which can be an organic light-emitting diode (OLED) display device, a light-emitting diode (LED) display device, a liquid crystal display (LCD) device, etc. This embodiment does not further limit the type of display device 100.

[0095] The display device 100 may include, but is not limited to, televisions, displays, tablets, laptops, mobile phones, etc. In this embodiment, the display device 100 will be used as a television as an example, but it is not limited to this example.

[0096] It is understandable that the display device 100 can be a borderless display device or a bordered display device. When the display device 100 is a borderless display device, a decorative frame 101 can be provided around the display device 100 to improve the aesthetics of the display device 100.

[0097] Optionally, the decorative frame 101 may include an upper frame 101a, a lower frame 101b, and two side frames 101c. The upper frame 101a is detachably disposed on the upper side of the display device 100, the lower frame 101b is detachably disposed on the lower side of the display device 100, and the two side frames 101c are detachably disposed on the two sides of the display device 100, respectively.

[0098] For example, the upper border 101a, lower border 101b, and side border 101c of the decorative frame 101 can be configured as a single piece, that is, the decorative frame 101 is a single piece. Of course, as another embodiment, the upper border 101a, lower border 101b, and side border 101c of the decorative frame 101 can also be configured as separate pieces, that is, the upper border 101a, lower border 101b, and side border 101c are each set independently. This application embodiment does not limit this.

[0099] In some embodiments, the display device 100 includes a display panel 10 for displaying images.

[0100] Please see Figure 4 , Figure 4This is a front view of the back panel provided in an embodiment of this application. In some embodiments, the display device 100 includes a back panel 20, which supports a display panel 10, which is disposed on the front side of the back panel 20. A light source (not shown) and an optical film assembly (not shown) are also disposed on the back panel 20, and the light source, the optical film assembly, and the display panel 10 are arranged sequentially from the rear side to the front side of the display device 100. Light emitted from the light source is projected onto the display panel 10 after passing through the optical film assembly, and image information is displayed on the display panel 10 after being processed by the display panel 10.

[0101] In some embodiments, the back panel 20 includes an upper edge 20c, a lower edge 20d, and two side edges 20e. The lower edge 20d and the upper edge 20c are disposed opposite each other along the height direction Z of the display panel 10. The two side edges 20e are disposed opposite each other along the width direction Y of the display panel 10, and the upper edge 20c, the lower edge 20d, and the two side edges 20e are connected and enclosed.

[0102] That is to say, the back panel 20 has an upper edge 20c and a lower edge 20d along the height direction Z, two side edges 20e along the width direction Y, and a front side (not shown) and a rear side (not shown) along the thickness direction X. Among them, the side of the display panel 10 facing the user is the front side, and the side of the display panel 10 away from the user is the rear side. When the display panel 10 is in a standing position (e.g., placed on a table by a base) or a hanging position (e.g., hung on a wall by a wall mount bracket), the absolute height of the upper edge 20c is higher than the absolute height of the lower edge 20d.

[0103] It can be understood that the extension direction between the upper edge 20c and the lower edge 20d is the height direction Z of the display panel 10, the extension direction between the two side edges 20e is the width direction Y of the display panel 10, and the extension direction between the front and rear sides is the thickness direction X of the display panel 10. It is known that among the width direction Y, the thickness direction X, and the height direction Z, each pair is perpendicular. That is to say, the width direction Y is perpendicular to the thickness direction X, the width direction Y is perpendicular to the height direction Z, and the thickness direction X is perpendicular to the height direction Z.

[0104] Please refer to the following: Figures 5 to 6A , Figure 5 This is an exploded view of the back panel, rear cover, radio module, and mounting bracket. Figure 6A for Figure 5 A partial enlarged view at point A. In some embodiments, the display device 100 includes a rear housing 30, which is connected to the side of the back plate 20 away from the display panel 10, that is, the rear housing 30 is disposed on the rear side of the back plate 20.

[0105] In some embodiments, the rear housing 30 and the back plate 20 together form a mounting cavity 21 (see [reference]). Figure 8 The mounting cavity 21 has an opening that connects to the outside of the display device 100, and the mounting cavity 21 is used to mount the motherboard, power board, etc.

[0106] It is understood that the mounting cavity 21 can be formed by the cooperation between the rear shell 30 and the back plate 20. For example, the rear shell 30 is recessed to form a concave structure, and the corresponding position of the back plate 20 also forms a concave structure. The two concave structures face each other and are connected together, so that the rear shell 30 and the back plate 20 together form the mounting cavity 21. Notches can be formed at the edges of the back plate 20 and the rear shell 30. The two notches face each other and are connected accordingly, thereby forming an opening on the mounting cavity 21 that communicates with the display device 100.

[0107] Specifically, the opening of the mounting cavity 21 is located at the upper edge 20c of the back plate 20, and the opening of the mounting cavity 21 communicates with the outside of the display device 100. Of course, as other embodiments, the opening of the mounting cavity 21 may also be located at the lower edge 20d of the back plate 20, or the opening of the mounting cavity 21 may also be located at the side edge 20e of the back plate 20, etc., and this application embodiment does not limit this.

[0108] Please see Figure 6B , Figure 6B This is a schematic diagram of the structure of the sound receiving module provided in an embodiment of this application. In some embodiments, the display device 100 includes a sound receiving module 40, which is disposed in the mounting cavity 21. The sound receiving module 40 has a first sound receiving hole 41, which is provided to expose the opening of the mounting cavity 21. The sound receiving module 40 collects external sound through the first sound receiving hole 41.

[0109] It is understandable that the first sound-receiving hole 41 is set to expose the first sound-receiving hole 41 to the opening of the mounting cavity 21, so that the first sound-receiving hole 41 is exposed to the outside of the display device 100, and the first sound-receiving hole 41 can be flush with the opening of the mounting cavity 21, which is conducive to the sound-receiving module 40 collecting the sound outside the display device 100 more effectively through the first sound-receiving hole 41, while also ensuring the overall consistency and aesthetics of the display device 100.

[0110] Optionally, when the decorative frame 101 is disposed on the outer periphery of the display device 100, the decorative frame 101 is provided with a second sound receiving hole 1011, which is connected to the opening of the mounting cavity 21, so that the first sound receiving hole 41 of the sound receiving module 40 can be connected to the outside of the display device 100 through the second sound receiving hole 1011.

[0111] In some embodiments, the display device 100 includes a mounting bracket 50 disposed within the mounting cavity 21 for supporting the radio module 40.

[0112] In some embodiments, the mounting bracket 50 is disposed on the upper edge 20c of the back plate 20, that is, the sound receiving module 40 is disposed on the upper edge 20c of the back plate 20, the opening of the mounting cavity 21 is opened on the upper edge 20c of the back plate 20, and the first sound receiving hole 41 of the sound receiving module 40 is disposed corresponding to the opening of the mounting cavity 21, so that the first sound receiving hole 41 faces the top side (that is, the upper side of the display device 100) for sound receiving.

[0113] Since the speakers of the display device 100 are usually located at the bottom or side of the display device 100, placing the microphone module 40 correspondingly on the upper side of the display device 100 can prevent the sound emitted by the speakers from being received by the microphone module 40, thus avoiding echoes or sound confusion and improving the voice recognition accuracy of the microphone module 40. Furthermore, since the display device 100 is usually placed on a table or mounted on a wall, and the user is usually located in front of the display panel 10, placing the microphone module 40 correspondingly on the upper side of the display device 100, with the first microphone hole 41 closer to the user's voice direction, results in better sound reception by the microphone module 40. At the same time, it can also effectively prevent the display device 100 from being blocked by other objects on the table, thus ensuring the clarity of the sound signal received by the microphone module 40.

[0114] The following explanation will be based on the example of mounting bracket 50 being set on the upper edge 20c of back plate 20, that is, the sound receiving module 40 being set on the upper side of display device 100, with the first sound receiving hole 41 facing the sky for sound receiving.

[0115] Please refer to the following: Figures 7 to 8 , Figure 7 This is a front view of the back panel, rear cover, radio module, and mounting bracket. Figure 8 for Figure 7 A cross-sectional view of BB. In some embodiments, the mounting bracket 50 is detachably connected to the back plate 20. This detachable connection between the mounting bracket 50 and the back plate 20 facilitates the disassembly, repair, and replacement of the radio module 40 by maintenance personnel, thereby improving the ease of maintenance of the display device 100.

[0116] It is understood that the detachable connection between the mounting bracket 50 and the back plate 20 may include, but is not limited to, screw connection, snap connection, magnetic connection, etc., and this application embodiment does not limit this.

[0117] The following description uses the mounting bracket 50 being connected to the back plate 20 via a snap-fit ​​connection as an example, but it is not limited to this example only.

[0118] In some embodiments, the back plate 20 is provided with a first snap hole 22, the rear shell 30 is provided with a first buckle 31, and the mounting bracket 50 is provided with a first through hole 50a communicating with the first snap hole 22. The first buckle 31 passes through the first through hole 50a and is fastened to the first snap hole 22, so that the mounting bracket 50 is clamped between the rear shell 30 and the back plate 20.

[0119] On the one hand, by detachably connecting the mounting bracket 50 to the back plate 20, and by providing a first through hole 50a on the mounting bracket 50, the first buckle 31 on the rear shell 30 passes through the first through hole 50a and directly engages with the first snap hole 22 on the back plate 20, thereby achieving one-time assembly and positioning between the mounting bracket 50, the rear shell 30 and the back plate 20, simplifying the assembly steps, reducing assembly errors caused by multiple assemblies, and improving the installation efficiency and installation effect of the display device 100.

[0120] On the other hand, by using the first buckle 31 on the back cover 30 to pass through the first through hole 50a of the mounting bracket 50 and directly engage with the first snap hole 22 on the back plate 20, it can effectively save the stacking space between structures, thereby achieving further thinning of the display device 100, which is conducive to realizing the lightweight design of the display device 100.

[0121] Meanwhile, since the mounting bracket 50 is detachably connected to the back plate 20, it also facilitates the disassembly, repair and replacement of the radio module 40, thereby improving the ease of maintenance of the display device 100.

[0122] Furthermore, compared to the screw-connected mounting method between the mounting bracket 50 and the back plate 20, the mounting bracket 50 in this embodiment is connected to the back plate 20 via a snap-fit ​​connection. This connection method eliminates the need for screws or other fasteners, avoids the need for threaded holes in the back plate 20, maintains the integrity of the back plate 20, and improves its structural strength. In addition, the snap-fit ​​connection reduces the use of tools and assembly time during assembly, thus helping to lower assembly costs.

[0123] Of course, as in other embodiments, the first card hole 22 can be provided on the rear shell 30 and the first buckle 31 can be provided on the back plate 20. This application embodiment does not limit this.

[0124] For example, the first buckle 31 can be a protrusion, a protruding post, or a protruding rib, etc. After passing through the first through hole 50a and the first locking hole 22, the first buckle 31 abuts against the first locking hole 22 to achieve the engagement of the first buckle 31 with the first buckle.

[0125] Optionally, the first fastening part 31 is provided with a reinforcing part 311, and the reinforcing part 311 has a clearance position for avoiding the mounting bracket 50. Since the first fastening part 31 needs to extend from the rear shell 30 and pass through the entire mounting bracket 50 before engaging with the first locking hole 22 on the back plate 20, the extension length of the first fastening part 31 is relatively long. Based on this, by providing a reinforcing part 311 on the first fastening part 31, the structural strength of the first fastening part 31 can be effectively improved, preventing the first fastening part 31 from breaking or deforming during assembly, thereby ensuring that the first fastening part 31 can smoothly engage with the first locking hole 22, and ensuring the stability of the assembly between the mounting bracket 50, the rear shell 30, and the back plate 20.

[0126] Furthermore, the clearance portion on the reinforcing part 311 is used to avoid interference between the reinforcing part 311 and the mounting bracket 50, thereby ensuring that the first fastening part 31 can smoothly pass through the first through hole 50a of the mounting bracket 50 and engage with the first snap hole 22. The shape of the reinforcing part 311 can be designed according to actual needs, for example, it can be set as a flat plate, an arc, or other shapes, and this embodiment does not limit it.

[0127] Please refer to the following: Figure 6A and Figure 9 , Figure 9 This is a schematic diagram of the mounting bracket and radio module provided in the embodiments of this application. In some embodiments of this application, the mounting bracket 50 is further provided with a second through hole 50b, and the rear shell 30 is further provided with a first limiting part 32. The first limiting part 32 passes through the second through hole 50b, which can provide initial positioning for the rear shell 30 when it is installed on the back plate 20, facilitating subsequent installation operations; it can also limit the movement of the mounting bracket 50 in a direction parallel to the surface of the rear shell 30, thereby limiting the position of the mounting bracket 50 relative to the rear shell 30. By setting the first limiting part 32 to pass through the second through hole 50b, the mounting bracket 50 is limited on the rear shell 30, further improving the stability of the assembly between the mounting bracket 50, the rear shell 30, and the back plate 20.

[0128] For example, the shape and size of the first limiting part 32 can be designed according to the shape and size of the second through hole 50b to ensure that the first limiting part 32 can be inserted into the second through hole 50b, thereby achieving an effective limiting function. For example, the first limiting part 32 can be configured as a protruding post, protrusion, or protruding strip, and the second through hole 50b can be configured as a hole-like structure that matches the first limiting part 32. Furthermore, the first limiting part 32 can also be formed into a conical structure so that the first limiting part 32 can be more easily inserted into the second through hole 50b, realizing rapid assembly between the mounting bracket 50 and the back plate 20. The conical structure can also serve as a guide, making it easier for the first limiting part 32 to align with the second through hole 50b during insertion, avoiding assembly deviations and improving assembly accuracy.

[0129] Please refer to the following: Figures 10 to 11 , Figure 10 for Figure 7 Sectional view of CC, Figure 11 for Figure 7 A cross-sectional view of DD. In some embodiments, the back plate 20 is provided with a first hook 23 and a first insertion hole 24. The mounting bracket 50 is provided with a limiting tongue 50c and a snap-fit ​​structure 50d. The limiting tongue 50c is located at the edge of the mounting bracket 50 and is inserted into the first insertion hole 24. The snap-fit ​​structure 50d is located on the mounting bracket 50 and is engaged with the first hook 23, so that the mounting bracket 50 is detachably connected to the back plate 20. By using the limiting tongue 50c located at the edge of the mounting bracket 50 and inserted into the first insertion hole 24 on the back plate 20, the initial positioning of the mounting bracket 50 on the back plate 20 is achieved through the cooperation between the limiting tongue 50c and the first insertion hole 24. Furthermore, based on the initial positioning of the mounting bracket 50 on the back plate 20 achieved by the cooperation of the limiting tongue 50c and the first insertion hole 24, the mounting bracket 50 is also provided with a snap-fit ​​structure 50d, which engages with the first hook 23 on the back plate 20, thereby achieving a detachable connection between the mounting bracket 50 and the back plate 20. This connection method is not only simple in structure and easy to implement, but also effectively reduces the assembly resistance between the mounting bracket 50 and the back plate 20, improving the installation efficiency and effect of the mounting bracket 50.

[0130] In some embodiments, the back plate 20 is further provided with a third through hole 25, and the mounting bracket 50 is provided with a second limiting part 50e, which passes through the third through hole 25 to restrict the movement of the mounting bracket 50 in a direction parallel to the surface of the back plate 20. By providing the second limiting part 50e passing through the second through hole 50b, the movement of the mounting bracket 50 in a direction parallel to the surface of the back plate 20 is restricted, thereby further improving the installation efficiency and installation effect of the mounting bracket 50 on the back plate 20.

[0131] For example, the shape and size of the second limiting part 50e can be designed according to the shape and size of the third through hole 25 to ensure that the second limiting part 50e can be inserted into the third through hole 25, thereby achieving an effective limiting function. For example, the second limiting part 50e can be set as a protruding post, protrusion, or protruding strip, and the third through hole 25 can be set as a hole-like structure adapted to the second limiting part 50e. Furthermore, the second limiting part 50e can also be formed into a conical structure so that the second limiting part 50e can be more easily inserted into the third through hole 25, realizing rapid assembly between the mounting bracket 50 and the back plate 20. The conical structure can also play a guiding role, making it easy for the second limiting part 50e to be aligned with the third through hole 25 during insertion, avoiding assembly deviation and improving assembly accuracy.

[0132] In some embodiments, the back panel 20 includes a main body 20a and a protrusion 20b. The protrusion 20b protrudes from the side of the main body 20a away from the display panel 10. The protrusion 20b is provided with a first insertion hole 24 and a first hook 23.

[0133] In some embodiments, the mounting bracket 50 is generally a rectangular bracket, comprising a first portion 51 and a second portion 52. The first portion 51 mates with the main body 20a to form a receiving cavity 511 between the first portion 51 and the main body 20a. The microphone module 40 is housed in the receiving cavity 511 and is detachably connected to the first portion 51. The second portion 52 is connected to the first portion 51 and is correspondingly disposed with respect to the protrusion 20b for connection to the protrusion 20b. The second portion 52 is provided with a limiting tongue 50c and a snap-fit ​​structure 50d.

[0134] By setting the first part 51 of the mounting bracket 50 to mate with the main body 20a to form a receiving cavity 511 for accommodating the radio module 40, and the second part 52 corresponding to the protrusion 20b of the back plate 20, the limiting tongue 50c and the snap-fit ​​structure 50d on the second part 52 can be closer to the first insertion hole 24 and the first hook 23 on the protrusion 20b. This avoids the limiting tongue 50c and the snap-fit ​​structure 50d needing to be too long, thus reducing the overall size of the mounting bracket 50 while facilitating assembly. In addition, the overall strength of the limiting tongue 50c and the snap-fit ​​structure 50d is also higher, making them less prone to breakage or deformation. Meanwhile, since the mounting bracket 50 is located on the upper edge 20c of the back plate 20, and the protrusion 20b protrudes from the side opposite to the display panel 10 onto the main body 20a, the first part 51, while engaging with the main body 20a, can also abut against the protrusion 20b, so that the protrusion 20b also provides upward support for the first part 51, ensuring that the first sound hole 41 of the sound receiving module 40 is as close as possible to the opening of the mounting cavity 21, thereby improving the sound receiving effect of the sound receiving module 40.

[0135] Please see Figure 12 , Figure 12 A front view of the mounting bracket and the radio module provided in an embodiment of this application. In some embodiments, the radio module 40 includes a pickup element 40a and a connecting wire 40b. The pickup element 40a is provided with a first microphone hole 41 (see...). Figure 6B The pickup element 40a is engaged with the first part 51, and one end of the connecting wire 40b is connected to the pickup element 40a. The second part 52 is provided with a wire groove 521 that communicates with the accommodating cavity 511, and the other end of the connecting wire 40b extends out from the wire groove 521.

[0136] As can be seen, the connection between the microphone 40a and the first part 51 also adopts a snap-fit ​​connection. This snap-fit ​​connection method facilitates the disassembly, repair, or replacement of the microphone module 40 by maintenance personnel, improving the maintenance convenience of the display device 100. Furthermore, one end of the connecting cable 40b is connected to the microphone 40a and is used to transmit the sound signal collected by the microphone 40a to the display device 100. The second part 52 is provided with a wire groove 521 communicating with the accommodating cavity 511. The wire groove 521 is used to collect the connecting cable 40b, and the other end of the connecting cable 40b extends from the wire groove 521 so that the other end of the connecting cable 40b can extend from the mounting bracket 50 and connect to the motherboard of the display device 100, thereby realizing the effective power supply of the microphone 40a.

[0137] In some embodiments, a limiting tongue 50c is disposed on the edge of the mounting bracket 50 along the first direction F1. Multiple snap-fit ​​structures 50d are provided, spaced apart along the second direction F2, with the limiting tongue 50c located between two adjacent snap-fit ​​structures 50d. The second direction F2 intersects the first direction F1. By placing the limiting tongue 50c between two adjacent snap-fit ​​structures 50d and on the edge of the mounting bracket 50 along the first direction F1, a three-point positioning structure is formed between the two snap-fit ​​structures 50d and the limiting tongue 50c. This three-point positioning structure further improves the positioning accuracy of the mounting bracket 50 on the back plate 20, further enhancing the stability of the connection between the mounting bracket 50 and the back plate 20. Simultaneously, since the limiting tongue 50c and the snap-fit ​​structures 50d are respectively located at different positions on the mounting bracket 50, the connection between the mounting bracket 50 and the back plate 20 is more reliable and less prone to loosening or detachment.

[0138] Optionally, the pickup element 40a can be a long strip-shaped structure, with multiple first sound receiving holes 41 spaced apart along the length of the pickup element 40a. Correspondingly, the receiving groove for accommodating the pickup element is adapted to the structure of the pickup element 40a, so that the mounting bracket 50 can also be a rectangular structure. For example, the first direction F1 can be the width direction Y of the mounting bracket 50, and the second direction F2 can be the length direction of the mounting bracket 50.

[0139] Please refer to the following: Figure 10 and Figure 13 , Figure 13 for Figure 12 A cross-sectional view of EE. In some embodiments, the snap-fit ​​structure 50d includes a first extension 51d and a second extension 52d. The first extension 51d extends from the mounting bracket 50 toward the back plate 20. One end of the second extension 52d is bent and connected to the first extension 51d, and extends from the back plate 20 toward the mounting bracket 50. The other end of the second extension 52d is suspended. A second buckle 53d is provided on the second extension 52d for engaging with the first hook 23. A gap is formed between the first extension 51d and the second extension 52d. The gap is configured to provide space for movement of the second extension 52d when it is subjected to force, so that the second extension 52d drives the second buckle 53d to disengage from the first hook 23.

[0140] By designing the specific structure of the snap-fit ​​structure 50d, a gap is formed between the first extension 51d and the second extension 52d. This design not only enhances the flexibility of the snap-fit ​​structure 50d but also ensures that it can smoothly disengage from the first hook 23 under force, facilitating the disassembly of the mounting bracket 50. Specifically, when it is necessary to disassemble the mounting bracket 50, an external force can be applied to the second extension 52d, thereby utilizing the gap to provide movement space for the second extension 52d. This allows the second extension 52d to drive the second buckle 53d out of the first hook 23 without damaging the snap-fit ​​structure 50d or the back plate 20, thus maintaining the structural integrity of the display device 100. Furthermore, since the movement space of the second extension 52d is provided by the gap formed between the first extension 51d and the second extension 52d, the release of the second buckle 53d on the second extension 52d only requires the use of the space of the mounting bracket 50 itself, without the back plate 20 providing additional movement space to the mounting bracket 50. This can effectively improve the space utilization of the back plate 20, thereby improving the space utilization of the display device 100.

[0141] Specifically, the first extension 51d can be a cylindrical, plate-shaped, strip-shaped, or block-shaped structure, the second extension 52d can be a cylindrical, plate-shaped, strip-shaped, or block-shaped structure, and the second fastening part 53d can be a protrusion, rib, or strip, etc. The embodiments of this application do not limit this.

[0142] Optionally, to further enhance the stability of the connection between the mounting bracket 50 and the back plate 20, a guide ramp is provided on the first hook 23 of the back plate 20. The guide ramp helps to guide the second buckle 53d of the buckle structure 50d to smoothly enter the first hook 23 when mounting the bracket 50, reducing assembly difficulty and improving assembly efficiency.

[0143] The following is a brief description of the installation process of the mounting bracket 50 between the back plate 20 and the rear cover 30:

[0144] First, the limiting tongue 50c on the mounting bracket 50 is tilted at a certain angle and inserted into the first insertion hole 24 on the back plate 20, so that the limiting tongue 50c abuts against the first insertion hole 24, thereby achieving initial positioning of the mounting bracket 50 on the back plate 20. Then, the mounting bracket 50 is rotated towards the back plate 20. At this time, the snap-fit ​​structure 50d and the second limiting part 50e on the mounting bracket 50 are respectively inserted into the first hook 23 and the third through hole 25, thereby completing the snap-fit ​​connection between the mounting bracket 50 and the back plate 20, so as to achieve detachable connection and precise positioning of the mounting bracket 50 on the back plate 20. Finally, the first buckle part 31 on the rear shell 30 is passed through the first through hole 50a and directly engaged with the first snap hole 22 on the back plate 20. At the same time, the first limiting part 32 on the rear shell is inserted into the second through hole 50b, which can further limit the position of the mounting bracket 50 relative to the rear shell 30.

[0145] The display device disclosed in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the display device and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
