Description

Technical Field

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

[0002] In the use of display devices, taking television as an example, users can usually choose to install a stand at the bottom to place the television on a table, or install a wall mount on the back to mount the television on the wall.

[0003] When using the "wall mounting" method, it is usually necessary to fix a connection structure with threaded holes to the back panel of the TV, so that the connection structure is exposed outside the back cover. Then, the wall mount bracket is fixed to the TV by screwing fasteners to the connection structure, thus achieving the function of wall mounting the TV.

[0004] However, the connection structure used in the related technology not only has the problem of unreliable connection, but also the problem of fasteners generating debris that falls into the TV during the assembly process. Utility Model Content

[0005] This application discloses a display device that can improve the reliability of the connection between the connection structure and the wall-mounted bracket, while also enhancing the safety of the display device.

[0006] To achieve the above objectives, embodiments of this application disclose a display device, including:

[0007] Display panel;

[0008] Backlight module, the backlight module comprising:

[0009] A back panel, located on the backlight side of the display panel, having a receiving space;

[0010] An optical component is disposed on the back plate, and the light source of the optical component is located in the receiving space;

[0011] The rear shell is connected to the back plate, and the rear shell covers part of the back plate so that part of the back plate is exposed outside the rear shell. The exposed part of the back plate forms an external area, and the external area is provided with a first clearance opening.

[0012] A first connection structure, configured to connect to a wall mount bracket to mount the display device on a wall, the first connection structure comprising:

[0013] A base, which is fixed to the back plate and located in the receiving space;

[0014] A connecting column is integrally formed with the base. The connecting column extends along a first direction and is provided with a first threaded hole. The first clearance opening is used to expose the first threaded hole on the connecting column to the outer area of ​​the back plate. The connecting column is connected to the wall-mounted bracket by a first fastener passing through the first threaded hole.

[0015] The first threaded hole is configured to not communicate with the accommodating space, and the first direction is the thickness direction of the display device.

[0016] The display device provided in this application integrally molds the base and connecting column. The base is placed in an accommodating space and fixedly connected to a back plate. The first threaded hole on the connecting column protrudes from the outer area of ​​the back plate through a first clearance opening, allowing the wall-mounted bracket to connect to the first threaded hole via a first fastener. This securely connects the wall-mounted bracket to the back plate, enabling the display device to be mounted on the wall. Compared to the riveting method used in related technologies, the first connecting structure in this application eliminates the riveting process, resulting in higher overall strength and reducing or eliminating the risk of connecting column detachment, thereby improving the reliability of the connection between the first connecting structure and the wall-mounted bracket. Furthermore, this first connecting structure is lower in cost, simpler in process, and more efficient in production compared to riveting.

[0017] Furthermore, since the light source of the optical components is typically located within the housing space of the back panel, and the base is located within this housing space and connected to the back panel, the first threaded hole on the connecting post is exposed through the first clearance opening to connect with the wall mount bracket. If the housing space of the display device is connected to the first threaded hole, debris generated during the assembly process of the first fastener may fall into the housing space through the first threaded hole, potentially affecting the optical components and thus posing a quality hazard to the display device. Therefore, this application also addresses this issue by setting the first threaded hole to be non-connected to the housing space. This prevents debris from falling into the display device through the first threaded hole during assembly, thereby improving the safety of the display device.

[0018] As an alternative implementation, the first threaded hole is configured as a blind hole so that the first threaded hole is not in communication with the receiving space.

[0019] By setting the first threaded hole as a blind hole, that is, the first threaded hole is not penetrated during machining, the machining process is simple and easy to form. Furthermore, by making the first threaded hole itself not penetrate, no additional blocking component is needed, which improves the sealing performance of the first connection structure itself, simplifies the design of the first connection structure itself, helps to reduce costs and has high reliability.

[0020] As an optional implementation, the connecting post includes:

[0021] A first column portion is integrally formed with the base. The first column portion extends along a first sub-direction and has a first inner cavity. The first column portion also has a first end and a second end opposite to each other. The first end is the end away from the base and has a first top wall for forming the first inner cavity.

[0022] The second column portion is integrally formed with the first column portion. The second column portion is located in the first inner cavity. The second column portion is connected to the first top wall and extends along the second sub-direction. The second column portion is provided with the first threaded hole. The end of the first threaded hole near the base is constructed as a closed end so that the first threaded hole is not connected to the receiving space.

[0023] The first direction includes a first sub-direction and a second sub-direction that are opposite to each other. The first sub-direction is the direction from the back plate to the rear shell, and the second sub-direction is the direction from the rear shell to the back plate.

[0024] By configuring the connecting post into a structure comprising a first column portion and a second column portion located inside the first column portion, the first column portion having a first inner cavity, such that the second column extends from the first top wall of the first column portion, that is, the first column portion is hollow, and the second column portion is integrally formed within the hollow first column portion, with a closed first threaded hole formed on the second column portion. It can be seen that the first column portion and the second column portion perform different functions. Since the first column portion is located on the outer periphery, its extension length along the first direction can be used to meet the assembly height when connected to the wall-mounted bracket, while the first threaded hole formed on the second column portion is used to meet the connection with the first fastener. Furthermore, because the first column portion has a first inner cavity, weight can be reduced, allowing the first connecting structure to combine lightweight and functionality.

[0025] For example, the first connecting structure can be made of sheet metal and employ a two-stage deep-drawing process. The first deep-drawing creates a first cylindrical portion on the periphery, forming a first inner cavity. This first cylindrical portion can accommodate the assembly height. The second deep-drawing creates a second cylindrical portion with a closed hole, and tapping is performed inside this closed hole to form a first threaded hole. This dual-cylinder structure design simplifies the processing and saves material, thereby reducing costs and improving production efficiency.

[0026] In one optional implementation, the first threaded hole is configured as a through hole, and the base includes:

[0027] The main body, wherein the connecting column is integrally formed with the main body;

[0028] A blocking portion, which bends from the edge of the main body portion to cover the first threaded hole, so that the first threaded hole is not in communication with the receiving space.

[0029] By designing the first threaded hole as a through hole, i.e., a through-hole, the machining process becomes easier and the machining efficiency is higher. Furthermore, by sealing the first threaded hole with the base's shielding portion, the first threaded hole is prevented from communicating with the receiving space. Therefore, this application not only utilizes the shielding portion to prevent the first threaded hole from communicating with the receiving space, thus preventing foreign objects from entering the receiving space through the first threaded hole, but also improves the machining efficiency of the connecting column.

[0030] In addition, the shielding part is bent from the edge of the main body to cover the first threaded hole, so that the shielding part and the main body are integrally formed without the need for additional assembly of the shielding part. This makes the first connecting structure a whole piece, which can not only ensure the reliability of the overall structure of the base, but also simplify the assembly process.

[0031] As an optional implementation, the first direction includes a first sub-direction and a second sub-direction that are opposite to each other, the first sub-direction being the direction from the back plate to the rear shell, and the second sub-direction being the direction from the rear shell to the back plate;

[0032] The connecting post extends along the first sub-direction, the connecting post extends along the first sub-direction, the connecting post has a second inner cavity, the connecting post also has a second top wall for forming the second inner cavity, the second top wall has a protrusion extending along the second sub-direction, the protrusion has the first threaded hole;

[0033] The first direction includes a first sub-direction and a second sub-direction that are opposite to each other. The first sub-direction is the direction from the back plate to the rear shell, and the second sub-direction is the direction from the rear shell to the back plate.

[0034] By providing a protrusion extending along a second sub-direction on the second top wall of the connecting post, and providing a through-hole in the protrusion, the protrusion increases the contact area and engagement length of the thread compared to ordinary straight-hole tapping, which is beneficial to improving the reliability of the connection between the first fastener and the connecting post. Furthermore, this type of connecting post can be manufactured by integrating stamping, flanging, and tapping during forming, making the first connection structure more suitable for mass production and reducing processing costs.

[0035] As an alternative implementation, the backplate has a first side facing the optical component, the base has a second side facing the backplate, the second side being in contact with the first side, and the connecting post extends out of the outer region of the backplate through the first clearance opening, so that the first threaded hole is exposed in the outer region;

[0036] The outer area is provided with a first through hole, and the base is provided with a second threaded hole, with the first through hole and the second threaded hole being arranged correspondingly along the first direction;

[0037] The display device further includes a second fastener, which passes through the first through hole and connects to the second threaded hole to fix the first connection structure on the back plate.

[0038] By placing the base in the receiving space of the back plate, the second side of the base is attached to the first side of the back plate, so that the connecting post extends out of the outer area of ​​the back plate through the first clearance opening. That is, in this application, only the base of the first connecting structure is located in the receiving space, while the connecting post extends to the outside through the first clearance opening. This allows the first connecting structure to not excessively occupy the internal space of the display device, thereby making the internal space smaller and the display device thinner overall. In other words, the first connecting structure is adapted to thin display device types with small receiving space.

[0039] Furthermore, since the outer area of ​​the back plate is exposed on the back cover to form the appearance of the display device, the first connection structure is fixed by setting a first through hole on the back plate for the second fastener to pass through and connect with the second threaded hole on the base. This allows the connecting column to be installed from the inside out, and the second fastener is assembled on the outside of the back plate, making the assembly method more reasonable.

[0040] As an optional implementation, the height of the connecting post along the first direction is 10mm to 15mm.

[0041] If the height of the connecting post along the first direction is too small, the exposed portion of the connecting post will be too short, and the depth of the first threaded hole will be too shallow. This will result in the first fastener being screwed in too shallowly, leading to insufficient connection strength. Consequently, the connection between the first connecting structure and the wall-mounted bracket will be unreliable, failing to meet sufficient screwing height. In particular, during mounting, the threads may gradually strip due to the load, eventually causing the fastener to loosen. Furthermore, if the exposed portion of the connecting post is too short, the end of the first fastener may hit the base and fail to tighten completely.

[0042] If the height of the connecting post along the first direction is too large, the weight of the display device will amplify the tensile force on the base and back plate, which may cause deformation of the first connecting structure after long-term use. Furthermore, an excessively long connecting post will protrude significantly beyond the back plate, affecting the overall aesthetics of the display device.

[0043] Therefore, by limiting the height of the connecting column to a reasonable range, it is possible to meet the assembly height requirements of the first connecting structure and the wall-mounted bracket through the first fastener, while also reducing the risk of deformation of the first connecting structure and ensuring the aesthetics of the display device.

[0044] As an optional implementation, the outer region is provided with a reinforcing rib, the reinforcing rib having a first surface and a third surface opposite to the first surface, the third surface being provided with a first recess and a first clearance opening, and the first through hole being located in the first recess;

[0045] The end of the second fastener is located in the first recess, such that the surface of the second fastener is lower than or flush with the third surface.

[0046] By setting reinforcing ribs on the back plate, the structural strength of the back plate can be enhanced and the deformation of the back plate shell can be prevented. The first recess, the first through hole, and the first clearance opening are all located at the reinforcing ribs. This can reduce the impact of back plate deformation or collapse during the locking process of the second fastener, thereby ensuring the reliability of the connection between the display device and the wall-mounted bracket.

[0047] Furthermore, by setting a first recessed platform on the third surface, with the first through hole located in the first recessed platform, and placing the end of the second fastener in the first recessed platform, and making the surface of the second fastener lower than or flush with the third surface, it is possible to ensure that the second fastener does not protrude from the third surface even when it is exposed outside the outer area of ​​the back plate, so that the third surface of the reinforcing rib is flat and without protrusions, thus ensuring the aesthetic appearance of the outer area of ​​the back plate as an exterior surface.

[0048] As an optional implementation, the base extends along a second direction, and the base has second threaded holes at both ends along the second direction, with the connecting post located between the two second threaded holes;

[0049] The base is bent away from the second surface by two opposite edges arranged perpendicular to the second direction to form a reinforcing part;

[0050] The second direction is perpendicular to the first direction.

[0051] By bending the edge of the base to form a reinforcing section, the structural strength of the base can be enhanced, so that when the base is connected to the back plate by the second fastener, even when the connecting column is subjected to the force of the wall mount bracket, it is not easy to deform, thus effectively ensuring the reliability of the first connection structure.

[0052] As an optional implementation, the display device further includes a second connection structure configured to connect to the wall mount bracket, the second connection structure being fixed to the back plate and located between the back plate and the rear shell, and the second connection structure having a third threaded hole;

[0053] The rear shell is provided with a second clearance opening, which is used to expose the third threaded hole on the rear shell. The second connection structure is connected to the third threaded hole through a third fastener to connect with the wall-mounted bracket.

[0054] By setting a second connection structure between the back panel and the rear shell to connect with the wall mount bracket, and combining it with the first connection structure set on the outer area of ​​the back panel, multiple connection points are formed on the back panel of the display device. When connected with the wall mount bracket and the display device is mounted on the wall, the force can be distributed, avoiding the situation where the back panel is deformed due to stress concentration at a single point, thus improving the reliability of the display device mounting.

[0055] Furthermore, since the second connecting structure is located between the back panel and the rear shell, that is, the second connecting structure is located in the part of the back panel that is covered by the rear shell, the second connecting structure can be hidden inside the display device, thereby reducing the requirements for the appearance of the second connecting structure, and thus reducing the design and assembly difficulty of the second connecting structure.

[0056] Compared with the prior art, the beneficial effects of this application are:

[0057] The display device provided in this application integrally molds the base and connecting column. The base is placed in an accommodating space and fixedly connected to a back plate. The first threaded hole on the connecting column protrudes from the outer area of ​​the back plate through a first clearance opening, allowing the wall-mounted bracket to connect to the first threaded hole via a first fastener. This securely connects the wall-mounted bracket to the back plate, enabling the display device to be mounted on the wall. Compared to the riveting method used in related technologies, the first connecting structure in this application eliminates the riveting process, resulting in higher overall strength and reducing or eliminating the risk of connecting column detachment, thereby improving the reliability of the connection between the first connecting structure and the wall-mounted bracket. Furthermore, this first connecting structure is lower in cost, simpler in process, and more efficient in production compared to riveting.

[0058] Furthermore, since the light source of the optical components is typically located within the housing space of the back panel, and the base is located within this housing space and connected to the back panel, the first threaded hole on the connecting post is exposed through the first clearance opening to connect with the wall mount bracket. If the housing space of the display device is connected to the first threaded hole, debris generated during the assembly process of the first fastener may fall into the housing space through the first threaded hole, potentially affecting the optical components and thus posing a quality hazard to the display device. Therefore, this application also addresses this issue by setting the first threaded hole to be non-connected to the housing space. This prevents debris from falling into the display device through the first threaded hole during assembly, thereby improving the safety of the display device. Attached Figure Description

Detailed Implementation

[0072] 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.

[0073] In this application, the terms "upper," "inner," "outer," "front," and "rear," 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.

[0074] 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.

[0075] Furthermore, the terms "set up," "equipped with," and "connected" 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.

[0076] 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.

[0077] Taking a television as an example, users can typically choose to install a wall mount bracket on the back of the television to mount it on the wall. Specifically, a connection structure with threaded holes is usually fixed to the back panel of the television, with the connection structure exposed outside the back cover. The wall mount bracket is then fixed to the television by screwing fasteners onto the connection structure, thus achieving the function of wall mounting the television.

[0078] One connection structure uses a sheet metal bracket attached to the back panel of the TV. This bracket is formed by bending a sheet metal part, roughly in the shape of a "U". The sheet metal bracket uses a flanging and tapping method to create a through-hole. Typically, this connection structure is fixed inside the display device, with the threaded hole exposed externally. However, because the back panel has clearance openings for this part to pass through, debris can easily accumulate inside the threaded hole when installing locking screws with a wall mount bracket. This debris can fall into the display device, potentially affecting the internal optical components and posing a quality risk. Furthermore, the sides of this bent sheet metal bracket are open, which, when the connection structure is exposed outside the display device as an external component, not only poses a risk of insect ingress but also affects the aesthetics.

[0079] Another connection structure involves directly riveting the nut post to the back plate, or first riveting the nut post to a base and then fixing the base to the back plate. However, with riveting, the nut post's connection relies primarily on the strength of the mutual pressure. For wall-mounted displays or large-sized products with significant weight, this places higher demands on the design and strength of the nut post's riveting. Insufficient design margins or fluctuations in manufacturing processes can lead to insufficient riveting strength, resulting in nut post breakage during actual use. This affects the stability of the connection structure and poses a safety hazard. Therefore, neither connection structure can simultaneously guarantee the reliability of the connection between the structure and the base or wall mount bracket, nor prevent debris from falling into the machine through the threaded holes during screw tightening.

[0080] Based on this, this application provides a display device that integrally molds a base and a connecting column. The base is positioned within an accommodating space and fixedly connected to a back plate. A first threaded hole on the connecting column protrudes from the outer area of ​​the back plate through a first clearance opening, allowing a wall-mounted bracket to connect to the first threaded hole via a first fastener. This securely connects the wall-mounted bracket to the back plate, enabling the display device to be mounted on a wall. Compared to the riveting method used in related technologies, the first connecting structure in this application eliminates the riveting process, resulting in higher overall strength and reducing or eliminating the risk of the connecting column detaching, thus improving the reliability of the connection between the first connecting structure and the wall-mounted bracket. Furthermore, by ensuring the first threaded hole is not connected to the accommodating space, this application prevents debris from falling into the display device through the first threaded hole during assembly, thereby enhancing the safety of the display device.

[0081] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0082] See Figure 1 and Figure 2 , Figure 1 The schematic diagram of the display device 1 is shown. Figure 2 An exploded view of the display device 1 is shown. This application discloses a display device 1, which can be, but is not limited to, electronic display products such as televisions, computer monitors, and liquid crystal display panels, and can be widely used in places such as homes, offices, conference halls, exhibition halls, stations, hospitals, or shopping malls.

[0083] In some embodiments, the display device 1 includes a display panel 101 for displaying image information for a user to view.

[0084] In some embodiments, the display panel 101 may include, but is not limited to, a liquid crystal display (LCD) or an organic light-emitting diode display (OLED), or other displays that can be used to achieve image display functions. This application embodiment does not specifically limit this.

[0085] In some embodiments, the display device 1 includes a backlight module 102, which is located on the backlight side of the display panel 101.

[0086] In some embodiments, the backlight module 102 includes a backplate 103 located on the backlight side of the display panel 101, and the backplate 103 has a receiving space 104. The backplate 103 serves as the main support for the display device 1 and is typically made of metal.

[0087] In some embodiments, the backlight module 102 includes an optical component 105. The optical component 105 includes a light source and a diaphragm assembly (not shown). The optical component 105 is disposed on a backplate 103, and the light source of the optical component 105 is located in a receiving space 104.

[0088] In some embodiments, the diaphragm assembly includes a reflective sheet, a diffuser plate, and an optical film arranged sequentially from back to front along the thickness direction of the display device 1. The display panel is located in front of the diaphragm assembly. Light emitted from the light source is reflected by the reflective sheet, passes sequentially through the diffuser plate and the optical film, and is then transmitted to the display panel. Liquid crystal molecules in the front panel are deflected by an electric field, reducing the transmittance of light emitted from the optical film to the display panel 101, thereby projecting the light onto filters of different colors to form an image. Multiple optical films may be included, and these films may include brightness enhancement sheets and multiple prism sheets, or multiple films may include multiple prism sheets.

[0089] See Figure 3In some embodiments, the display device 1 includes a rear shell 106 connected to a back plate 103. The rear shell 106 covers a portion of the back plate 103, allowing a portion of the back plate 103 to be exposed. The exposed portion of the back plate 103 forms an external region 1031, which has a first clearance opening 103a. It is understood that the rear shell 106 is connected to the back plate 103 to cover the outside of the back plate 103, thereby protecting a portion of the internal structure of the display device 1. A portion of the back plate 103 is covered by the rear shell 106, while another portion of the back plate 103 is exposed, forming the external region 1031. That is, in addition to the rear shell 106 serving as an exterior component, the external region 1031 of the back plate 103 is also exposed as an exterior component. Meanwhile, in order to facilitate maintenance of the internal structure of the display device 1, the back cover 106 also needs to be removable relative to the back plate 103.

[0090] In order to enable the display device 1 to have multiple uses, in some embodiments the display device 1 includes a wall mount bracket for mounting the display device 1 on a wall or placing it on a table.

[0091] It is understood that the wall mount bracket is connected between the display device 1 and the wall to mount the display device 1 on the wall.

[0092] Taking the display device 1 as a television as an example, "wall mounting" can refer to: installing a wall mount bracket on the back of the television to mount the television on the wall.

[0093] In some embodiments, the display device 1 includes a first connection structure 200 configured to connect with a wall mount bracket to mount the display device 1 on a wall. Specifically, the first connection structure 200 is disposed on the display device 1 for connection with the wall mount bracket to achieve the mounting of the display device 1.

[0094] See Figure 3 and Figure 4 In some embodiments, the first connection structure 200 includes a base 10, which is fixed to the back plate 103 and located in the receiving space 104. It can be understood that the back plate 103 serves as the main support for the display device 1. When installing the first connection structure 200, the first connection structure 200 is fixed by fixing the base 10 to the back plate 103, which ensures the reliability of the installation of the first connection structure 200.

[0095] In some embodiments, the first connection structure 200 includes a connecting post 20, which is integrally formed with the base 10. The connecting post 20 extends along a first direction X and is provided with a first threaded hole 201.

[0096] Optionally, the base 10, serving as a support base for the connecting column 20, can be a thin structure such as a plate or block, to achieve effective connection with the back plate 103. Since the connecting column 20 and the base 10 are integrally formed, meaning the first connecting structure 200 is made entirely of the same material, it can be made of steel, aluminum alloy, or other materials with sufficient strength and load-bearing capacity. The first connecting structure 200 can be formed by stamping a single metal sheet or by die-casting.

[0097] Combination Figure 4 In some embodiments, a first clearance opening 103a is provided on the outer region 1031. This first clearance opening 103a is used to expose the first threaded hole 201 on the connecting post 20 in the outer region 1031 of the back plate 103. The connecting post 20 is connected to the wall mount bracket by a first fastener (not shown) passing through the first threaded hole 201. In other words, the wall mount bracket can be connected to the connecting post 20 by the first fastener and the first threaded hole 201, thereby realizing the connection between the wall mount bracket and the first connecting structure 200. It can be understood that the first clearance opening 103a is located in the outer region of the back plate 103. Wherein, the first direction X is the thickness direction of the display device 1.

[0098] Optionally, the first connecting structure 200 may be entirely located within the receiving space 104, with the first threaded hole 201 exposed on the rear shell 106 only through the first clearance opening 103a, allowing the first fastener to be inserted. Alternatively, the first connecting structure 200 may have only the base 10 located within the receiving space 104, while the connecting post 20 extends to the outside of the rear shell 106 through the first clearance opening 103a. The connection method of the first connecting structure 200 with the back plate 103 and the rear shell 106 in this manner will be described in detail in subsequent embodiments.

[0099] The display device 1 provided in this application integrally forms a base 10 and a connecting post 20. The base 10 is disposed in an accommodating space 104 and fixedly connected to a back plate 103. The first threaded hole on the connecting post 20 is exposed on the outer area 1031 of the back plate 103 through a first clearance opening 103a. This allows a wall-mounting bracket to be connected to the first threaded hole 201 via a first fastener, thereby fixing the wall-mounting bracket to the back plate 103 and allowing the display device 1 to be mounted on a wall. Compared to the riveting method using the connecting post 20 in related technologies, the first connecting structure 200 in this application eliminates the riveting process, resulting in higher overall strength and reducing or eliminating the risk of the connecting post 20 falling off, thus improving the reliability of the connection between the first connecting structure 200 and the wall-mounting bracket. Furthermore, compared to the riveting method, this first connecting structure 200 has lower cost, simpler process, and higher production efficiency.

[0100] Optionally, the first fastener can be a bolt, screw, or stud, as long as it can achieve threaded connection between the threaded structure and the first threaded hole 201 of the connecting post 20, thereby realizing the connection between the wall bracket and the first connecting structure 200.

[0101] Since the light source of the optical component 105 is usually located in the receiving space 104 of the back plate 103, the optical component 105 is mounted on the back plate 103, and the base 10 is located in the receiving space 104 and connected to the back plate 103. The first threaded hole 201 on the connecting post 20 is exposed through the first clearance opening 103a to connect with the wall mount bracket. It can be seen that in the related technology, whether the first connecting structure 200 with a through threaded hole is formed by flanging and tapping, or the first connecting structure 200 is directly riveted with a nut post, its threaded hole is a through hole. As a result, when the first connecting structure 200 is fixed to the back plate 103, the receiving space 104 of the display device 1 is connected to the first threaded hole 201. The debris generated by the first fastener during the assembly process may fall into the receiving space 104 through the first threaded hole 201, which may affect the optical component 105 and thus bring potential quality problems to the display device 1. Specifically, at least a portion of the light source and reflector in the receiving space 104 extends into the receiving space 104. If the first threaded hole 201 is connected to the receiving space 104, the debris generated during the assembly of the first fastener will fall into the receiving space 104 through the open first threaded hole 201, which will affect components such as the reflector, diffuser plate, and light source, thus posing a certain safety hazard.

[0102] Therefore, in some embodiments, the first threaded hole 201 is configured not to communicate with the receiving space 104. This prevents foreign objects from entering the receiving space 104 through the first threaded hole 201. For example, when the first fastener is screwed into the first threaded hole 201, it may generate debris. This configuration can prevent debris from falling into the receiving space 104.

[0103] This application also prevents foreign objects from entering the receiving space 104 through the first threaded hole 201 by setting the first threaded hole 201 to be non-communicating with the receiving space 104. This avoids the problem of debris falling into the display device 1 through the first threaded hole 201 during the assembly process of the first fastener, thereby improving the safety of the display device 1.

[0104] Continue reading Figure 4 In some embodiments, the back plate 103 has a first surface 103b facing the optical component 105, the base 10 has a second surface 10a facing the back plate 103, the second surface 10a is in contact with the first surface 103b, and the connecting post 20 extends out of the outer region 1031 of the back plate 103 through the first clearance opening 103a so that the first threaded hole 201 is exposed in the outer region 1031.

[0105] In some embodiments, the outer region 1031 is provided with a first through hole 103e, and the base 10 is provided with a second threaded hole 10d. The first through hole 103e and the second threaded hole 10d are correspondingly arranged along a first direction X. The display device 1 also includes a second fastener 30, which passes through the first through hole 103e and the second threaded hole 10d to connect and fix the first connecting structure 200 to the back plate 103.

[0106] Based on the base 10 being placed in the receiving space 104 between the back plate 103 and the rear shell 106, the second surface 10a of the base 10 is attached to the first surface 103b of the rear shell 106, so that the connecting post 20 extends out of the outer area 1031 of the back plate 103 through the first clearance opening 103a. That is, in this application, only the base 10 of the first connecting structure 200 is located in the receiving space 104, while the connecting post 20 passes through the first clearance opening 103a to the outside. This allows the first connecting structure 200 to not excessively occupy the internal space of the display device, thereby making the internal space smaller and the display device 1 thinner overall. In other words, the first connecting structure 200 is adapted to the type of thin display device 1 with a small receiving space 104.

[0107] Furthermore, since the outer area 1031 of the back plate 103 is exposed on the back cover 106 to form the appearance of the display device 1, the first connecting structure 200 is fixed by providing a first through hole 103e on the back plate 103 for the second fastener 30 to pass through and connect with the second threaded hole 10d on the base 10. This allows the connecting column 20 to be installed from the inside out, and the second fastener 30 to be assembled on the outside of the back plate 103, making the assembly method more reasonable.

[0108] Preferably, the base 10 is a thin plate, and the maximum size range of the base 10 in the first direction X can be 1mm to 4mm, for example, it can be 1.2mm, 2mm, 3.4mm or 4mm, etc. In this way, when only the base 10 is located in the accommodating space 104, the base 10 can avoid excessively occupying the space between the back plate 103 and the rear shell 106, so that the first connecting structure 200 is more suitable for thin display devices 1.

[0109] In some embodiments, the height of the connecting post 20 along the first direction X is 10mm to 15mm. Optionally, the height of the connecting post 20 along the first direction X can be 10mm to 13mm, 11mm to 14mm, 12mm to 15mm, or 13mm to 15mm, for example, it can be 10mm, 12mm, 13mm, or 15mm.

[0110] If the height of the connecting post 20 along the first direction X is too small, the exposed portion of the connecting post 20 will be too short, and the depth of the first threaded hole 201 will be too small. This will result in the first fastener being screwed in too shallowly, leading to insufficient connection strength. Consequently, the connection between the first connecting structure 200 and the wall-mounted bracket will be unreliable, failing to meet sufficient screw height. In particular, during installation, the threads may gradually strip due to the load, eventually leading to loosening. Furthermore, if the exposed portion of the connecting post 20 is too short, for example, only 5mm, the end of the first fastener may hit the base 10 and cannot be fully tightened.

[0111] If the height of the connecting post 20 along the first direction X is too large, the weight of the display device 1 will amplify the tension on the base 10 and the back plate 103, which may cause the first connecting structure 200 to deform after long-term use. In addition, the excessively long connecting post 20 will protrude significantly from the back plate 103, affecting the overall aesthetics of the display device 1.

[0112] Therefore, by limiting the height of the connecting column 20 to a reasonable range, the assembly height of the first connecting structure 200 and the wall bracket assembled with the first fastener can be met, while also reducing the risk of deformation of the first connecting structure 200 and ensuring the aesthetics of the display device 1.

[0113] In some embodiments, the outer region 1031 is provided with a reinforcing rib 103j, the reinforcing rib 103j has a first surface 103b, the reinforcing rib 103j also has a third surface 103c opposite to the first surface 103b, the third surface 103c is provided with a first recessed platform 103d and a first clearance opening 103a, and a first through hole 103e is located in the first recessed platform 103d.

[0114] By setting reinforcing ribs on the back plate 103, the structural strength of the back plate 103 can be enhanced and the shell deformation of the back plate 103 can be prevented. The first recessed platform 103d, the first through hole 103e, and the first clearance opening 103a are all located at the reinforcing rib 103j. This can reduce the impact of deformation or collapse of the back plate 103 during the locking process of the second fastener 30, thereby ensuring the reliability of the connection between the display device 1 and the wall bracket.

[0115] Optionally, the reinforcing rib 103j may include multiple reinforcing ribs, which may extend along the height and / or width of the display device 1.

[0116] like Figure 4 As shown, in some embodiments, the end of the second fastener 30 is located in the first recess 103d, so that the surface of the second fastener 30 is lower than or flush with the third surface 103c.

[0117] By providing a first recessed platform 103d on the third surface 103c of the back plate 103, such that the first through hole 103e is located in the first recessed platform 103d, and the end of the second fastener 30 is located in the first recessed platform 103d, and the surface of the second fastener 30 is lower than or flush with the third surface 103c, the second fastener 30 will not protrude from the third surface 103c of the back plate 103 even when it is exposed outside the outer area 1031 of the back plate 103. This ensures that the third surface 103c of the back plate 103 is flat and without protrusions, thus ensuring the aesthetic appearance of the outer area 1031 of the back plate 103 as an exterior surface.

[0118] In some embodiments, the first recess 103d is recessed in the direction toward the second surface 10a to form a first protrusion 103f on the first surface 103b.

[0119] In some embodiments, the base 10 further has a fourth surface 10b opposite to the second surface 10a. A second recess 10c is provided on the second surface 10a. The second recess 10c is recessed in the direction toward the fourth surface 10b to form a second protrusion 10e on the fourth surface 10b. A second threaded hole is located in the second recess 10c. A first protrusion 103f is accommodated in the second recess 10c so that the second surface 10a fits against the first surface 103b.

[0120] If the first recess 103d is directly opened on the third surface 103c of the back plate 103 and the first through hole 103e is set in the first recess 103d, the depth of the first through hole 103e will be reduced, making the strength of the first recess 103d relatively weak. This may cause the second fastener 30 to deform or break at the connection point as it gradually tightens by passing through the first through hole 103e and connecting with the second threaded hole 10d on the base 10. Therefore, by setting the first recess 103d to be recessed on one side and protruding on the other side, the structural strength of the connection point will not be weakened due to excessive thinning of the wall thickness of the back plate 103, even if the first recess 103d is opened on the back plate 103, thus ensuring the connection strength at the connection point.

[0121] Furthermore, the interlocking of the first protrusion 103f and the second recessed platform 10c ensures a smooth fit between the back plate 103 and the base 10, and ensures accurate alignment between the back plate 103 and the base 10, thus reducing assembly errors.

[0122] Optionally, the second fastener 30 can be a bolt, screw, or stud, as long as it can have a threaded structure and a second threaded hole 10d to achieve a threaded connection, thereby achieving the connection between the first connection structure 200 and the back plate 103.

[0123] In some embodiments, the base 10 extends along the second direction Y, and both ends of the base 10 along the second direction Y are provided with second threaded holes 10d, and the connecting post 20 is located between the two second threaded holes 10d.

[0124] Wherein, the second direction Y is perpendicular to the first direction X. Optionally, the second direction Y can be the width direction of the display device 1, that is, the left-right direction of the display device 1, or the second direction Y can also be the height direction of the display device 1, that is, the up-down direction of the display device 1.

[0125] As can be seen, in this application, the base 10 is roughly in the shape of a long strip plate, the connecting post 20 is located in the middle of the long strip plate-shaped base 10, and the base 10 is provided with a second countersunk 10c and a second threaded hole 10d on both sides of the connecting post 20, so that the second fastener 30 can pass through and connect with the second threaded hole 10d.

[0126] Preferably, the second countersunk platform 10c and the second threaded hole 10d located on both sides of the connecting column 20 are symmetrically arranged. When the symmetrically arranged second threaded hole 10d is connected with the second fastener 30, the two ends of the base 10 can be subjected to balanced force, avoiding stress concentration on one side, thereby making the base 10 more firmly fixed.

[0127] It is worth noting that the first recessed platform 103d, the first through hole 103e, and the first clearance opening 103a are all located on the reinforcing rib 103j, meaning that the first connecting structure 200 is also located at the reinforcing rib 103j. In this embodiment, the first connecting structure 200 may include multiple structures, each of which, fixed to the back plate 103, forms a connection position on the display device 1. These multiple first connecting structures 200 may all be located at the reinforcing rib 103j, or some of the first connecting structures 200 may be located at the reinforcing rib 103j while others may not be located there. For example, the first connecting structure 200 may include two structures, both located at the reinforcing rib 103j, and spaced apart along the width direction of the display device 1.

[0128] In some embodiments, the display device 1 further includes a second connection structure 300, which is configured to be connected to a wall mount bracket. The second connection structure 300 is fixed to the back plate 103 and located between the back plate 103 and the rear shell 106. The second connection structure 300 is provided with a third threaded hole (not shown).

[0129] In some embodiments, the rear housing 106 is provided with a second clearance opening 106a, which is used to expose the third threaded hole on the rear housing 106. The second connection structure 300 is connected to the third threaded hole through a third fastener (not shown) to connect with the wall mount bracket.

[0130] By providing a second connecting structure 300 between the back plate 103 and the rear shell 106 to connect with the wall mount bracket, and combining it with the first connecting structure 200 provided on the outer area of ​​the back plate 103, multiple connection points are formed on the back plate 103 of the display device 1. When connected with the wall mount bracket and the display device 1 is mounted on the wall, the force can be distributed, avoiding the situation where the back plate 103 is deformed due to stress concentration at a single point, thus improving the reliability of the mounting of the display device 1.

[0131] Furthermore, since the second connecting structure 300 is located between the back plate 103 and the rear shell 106, that is, the second connecting structure is located in the part of the back plate 103 covered by the rear shell 106, the second connecting structure 300 can be hidden inside the display device 1, thereby reducing the appearance requirements of the second connecting structure 300, and thus reducing the design and assembly difficulty of the second connecting structure 300.

[0132] In this embodiment, by setting a first connecting structure 200 and a second connecting structure 300 to form multiple connection positions on the display device 1 for connection with the wall mount bracket, the reliability of the connection between the wall mount bracket and the display device 1 can be more effectively guaranteed. Taking two of each of the first connecting structures 200 and 300 as an example, the first connecting structures 200 and 300 can be arranged diagonally. The two first connecting structures 200 are located near the top of the display device and are spaced apart along the width direction of the display device 1. The other two second connecting structures 300 are located below the two first connecting structures 200 and are respectively arranged in the height direction of the display device 1 corresponding to the two first connecting structures 200. Ultimately, the four connection positions formed on the display device 1 are roughly square, so that the display device 1 as a whole relies on the four connection positions to achieve a stable connection with the wall mount bracket. Of course, in other embodiments, the two first connecting structures 200 and the two second connecting structures 300 can be staggered in the height direction of the display device 1.

[0133] See Figure 5 and Figure 6 In some embodiments, the base 10 has two opposite edges arranged perpendicular to the second direction Y bent in a direction away from the second surface 10a to form a reinforcing portion 11.

[0134] By bending the edge of the base 10 to form a reinforcing part, the structural strength of the base 10 can be enhanced, so that when the base 10 is connected to the back plate 103 by the second fastener 30, even when the connecting column 20 is subjected to the force of the wall bracket, it is not easy to deform, thereby effectively ensuring the reliability of the first connecting structure 200.

[0135] In some embodiments, the first threaded hole 201 is configured as a blind hole so that the first threaded hole 201 is not in communication with the receiving space 104. That is, when the hole is machined on the connecting post 20, a non-penetrating hole is formed, and threads are formed by tapping in the non-penetrating hole, ultimately forming the first threaded hole 201 as a blind hole.

[0136] By setting the first threaded hole 201 as a blind hole, that is, the first threaded hole 201 is not penetrated when it is machined, the machining process is simple and easy to form. Furthermore, by making the first threaded hole 201 itself not penetrated, no additional blocking component is needed, which improves the sealing performance of the first connecting structure 200 itself, simplifies the design of the first connecting structure 200 itself, helps to reduce costs and has high reliability.

[0137] Combination Figures 5 to 7 In some embodiments, the first direction X includes a first sub-direction X1 and a second sub-direction X2 that are opposite to each other. The first sub-direction X1 is the direction from the back plate 103 to the rear shell 106, and the second sub-direction X2 is the direction from the rear shell 106 to the back plate 103.

[0138] In some embodiments, the connecting post 20 includes a first post portion 21, which is integrally formed with the base 10. The first post portion 21 extends along a first sub-direction X1 and has a first inner cavity 21a. The first post portion 21 also has a first end 21b and a second end 21c opposite to each other. The first end 21b is the end away from the base 10 and has a first top wall 21a1 for forming the first inner cavity 21a.

[0139] In some embodiments, the connecting post 20 includes a second post portion 22, which is integrally formed with the first post portion 21. The second post portion 22 is located in the first inner cavity 21a, connected to the first top wall 21a1, and extends along the second sub-direction X2. The second post portion 22 is provided with a first threaded hole 201. The end of the first threaded hole 201 near the base 10 is configured as a closed end so that the first threaded hole 201 is not in communication with the receiving space 104.

[0140] In this embodiment, the first threaded hole 201 has a closed end and an open end. The open end is located at the first end 21b of the first column portion 21, allowing the first fastener to enter the first threaded hole 201. The closed end is located at the second end 21c near the first column portion 21, so that the first threaded hole 201 is not in communication with the receiving space 104.

[0141] It should be noted that since the first threaded hole 201 is a blind hole, if only the thread length of the first threaded hole 201 is made to meet the screwing requirements, the first fastener will be screwed in to a shallow depth, which cannot guarantee the reliability of the screwing connection. Therefore, the extension length of the second main body 12 can extend to a position close to the base 10, while ensuring that the first threaded hole 201 meets the screwing length requirements, but still ensuring that the closed end of the second column 22 is located in the first inner cavity 21a. This allows the first fastener to be screwed in to a sufficient depth. For example, the second column 22 extends from the first end 21b of the first column 21 to the second end 21c of the first column 21, so that the closed end of the second column 22 extends to the position corresponding to the second surface 10a of the base 10, so that the first threaded hole 201 has sufficient depth, thereby allowing the first fastener to be screwed in deeper.

[0142] By configuring the connecting post 20 into a structure including a first post portion 21 and a second post portion 22 located inside the first post portion 21, the first post portion has a first inner cavity, such that the second post extends from the first top wall 21a1 of the first post portion, that is, the first post portion 21 is hollow. The second post portion 22 is integrally formed in the hollow first post portion 21, and a closed first threaded hole 201 is formed on the second post portion 22. It can be seen that the first post portion 21 and the second post portion 22 perform different functions. Since the first post portion 21 is located on the outer periphery, its extension length along the first direction X can be used to meet the assembly height when connected with the wall mount bracket, while the first threaded hole 201 formed on the second post portion 22 is used to meet the connection with the first fastener. Furthermore, since the first post portion 21 has a first inner cavity 21a, the weight can be reduced, so that the first connecting structure 200 takes into account both lightweight and functional characteristics.

[0143] For example, the first connecting structure 200 can be made of sheet metal and employ a two-stage deep-drawing process. First, a first columnar portion 21 is deep-drawn along the first sub-direction X1, forming a first inner cavity 21a. This first columnar portion 21 can be used to meet assembly height requirements. Second, a second columnar portion 22 with a closed hole is deep-drawn in the reverse direction along the second sub-direction X2, and tapping is performed inside this closed hole to form a first threaded hole 201. This dual-column structure design simplifies the processing and saves material, thereby reducing costs and improving production efficiency.

[0144] Of course, in some embodiments, the first connecting structure 200 can also be formed by die casting, and a first threaded hole 201, which is a blind hole, can be opened on the die-cast connecting column 20. That is, in the embodiments of this application, the first threaded hole 201 is formed on the solid connecting column 20. In this way, the connecting column 20 can also have a first threaded hole 201 that is not connected to the receiving space 104.

[0145] See Figures 8 to 10 In some embodiments, the first threaded hole 201 is configured as a through hole. The base 10 includes a main body 12 and a blocking portion 13, with the connecting post 20 integrally formed with the main body 12. The blocking portion 13 is bent from the edge of the main body 12 to cover the first threaded hole 201, so that the first threaded hole 201 is not in communication with the receiving space 104.

[0146] As mentioned above, the base 10 is a long strip, with opposing long and short sides. To avoid affecting the normal function of the second threaded hole 10d during bending of the obstruction portion 13, the obstruction portion 13 is bent from the edge of the long side of the base 10, and the dimension of the obstruction portion 13 in the second direction Y is smaller than the dimension of the base 10 in the second direction Y. In other words, the obstruction portion 13 can be made as small as possible while still being able to cover the second inner cavity 12a. This saves material and reduces costs while avoiding the impact on the second threaded hole 10d after bending an excessively long obstruction portion 13.

[0147] By configuring the first threaded hole 201 as a through hole, that is, by making the hole machining process easier and the machining efficiency higher, and by sealing the first threaded hole with the shielding part 13 of the base 10, the first threaded hole 201 can be prevented from communicating with the receiving space 104. It can be seen that, in addition to using the shielding part 13 to prevent the first threaded hole 201 from communicating with the receiving space 104, thus preventing foreign objects from entering the receiving space 104 through the first threaded hole 201, this embodiment of the application can also improve the machining efficiency of the connecting post 20.

[0148] In addition, the shielding part 13 is bent from the edge of the main body part 12 to cover the first threaded hole 201, so that the shielding part 13 and the main body part 12 are integrally formed without the need for additional assembly of the shielding part 13. This makes the first connecting structure 200 an integral piece, which can ensure the reliability of the overall structure of the base 10 and simplify the assembly process.

[0149] Optionally, both the shielding part 13 and the main body part 12 are thin plate structures, so that even if the shielding part 13 is bent on the side of the main body part 12 near the back plate 103, the base 10 can still be kept as thin as possible.

[0150] Combination Figure 10 In some embodiments, the connecting post 20 extends along a first sub-direction X1, the connecting post 20 has a second inner cavity 12a, the connecting post 20 also has a second top wall 12a1 for forming the second inner cavity, the second top wall 12a1 is provided with a protrusion 23 extending along the second sub-direction X2, and the protrusion 23 is provided with a first threaded hole 201.

[0151] By providing a protrusion 23 extending along the second sub-direction X2 on the second top wall 12a1 of the connecting post 20, and providing a through first threaded hole 201 on the protrusion 23, the protrusion 23 can increase the contact area of ​​the thread and increase the engagement length compared with ordinary straight hole tapping, which is beneficial to improving the reliability of the connection between the first fastener and the connecting post 20. At the same time, the flanged threaded hole can be processed by stamping and flanging in one step, making the first connection structure 200 more suitable for mass production and reducing processing costs.

[0152] 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.
