Description

Technical Field

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

[0002] For example, in display devices such as televisions and monitors, the circuit boards inside the display device typically have various terminals, which allow the display device to connect to other external devices. Terminal blocks are usually installed at the locations of the terminals to shield the internal circuit boards, preventing them from being exposed and improving the appearance. The terminal blocks also have corresponding clearance openings for the terminals, allowing connectors from other external devices to connect to the terminals through these clearance openings.

[0003] Taking a television as an example, a television typically consists of a back panel, a rear shell, and a terminal board. The rear shell is connected to the back panel, and the terminal board is connected to the rear shell. Currently, the terminal board is usually connected to the rear shell using screws. However, the method of providing threaded holes on the terminal board for screw connection is prone to stripping during connection. To solve the stripping problem, the screw length of the threaded hole section is usually increased, resulting in a thicker portion of the terminal board. Utility Model Content

[0004] This application discloses a display device that can reduce the risk of stripping when the rear shell is connected to the terminal board, and can reduce the thickness of the connection part of the terminal board.

[0005] To achieve the above objectives, embodiments of this application disclose a display device, including:

[0006] Back panel;

[0007] The rear shell is connected to the back plate and has a first through hole and an opening.

[0008] A circuit board is fixed to the side of the back plate facing the rear shell, and the circuit board is provided with connection terminals, which are arranged corresponding to the opening;

[0009] Terminal board, the terminal board comprising:

[0010] The main body plate is connected to the circuit board and located at the opening, and the main body plate has a clearance opening corresponding to the position of the connection terminal;

[0011] The connecting part is made of plastic. The connecting part is connected to the body plate and extends along a first direction. The connecting part is provided with a second through hole. The second through hole is provided in a second direction and corresponds to the first through hole. The first direction is perpendicular to the second direction, and the second direction is the thickness direction of the display device.

[0012] A sheet metal part, the sheet metal part being fixed to the connecting part, the sheet metal part having a first threaded hole, the first threaded hole being arranged in a second direction corresponding to the second through hole;

[0013] The first threaded fastener is used to thread the rear housing through the first through hole and the first threaded hole, so that the connecting part and the sheet metal part are both connected to the rear housing, thereby realizing the connection between the terminal plate and the rear housing.

[0014] In the display device provided in this application, the terminal board's connecting portion serves as the part connected to the rear housing. Since this connecting portion is made of plastic, if a first threaded fastener is directly threaded through the first through-hole on the rear housing and screwed into the connecting portion, the connecting portion may slip during rotation due to its low coefficient of friction or susceptibility to deformation, leading to stripping of the threads. To solve this stripping problem, increasing the depth of the second through-hole to increase the threaded length of the first threaded fastener connection would increase the thickness of the connecting portion, hindering the overall thickness reduction of the terminal board.

[0015] Based on this, this application fixes a sheet metal part to the connecting part of the terminal board. On one hand, a first threaded hole is formed on the sheet metal part, and simultaneously, the first through hole on the rear shell, the first threaded hole on the sheet metal part, and the second through hole on the connecting part are correspondingly arranged along a second direction. This allows a first threaded fastener to be threaded through the first through hole and the first threaded hole, thus achieving a threaded connection between the rear shell and the sheet metal part. Since the sheet metal part is fixed to the connecting part, the terminal board can be connected to the rear shell via the sheet metal part. In other words, in this application, the sheet metal part fixing the connecting part of the terminal board allows the first threaded fastener to be threaded onto the sheet metal part. Because the sheet metal part is made of metal, it has a high coefficient of friction and high hardness, making it less prone to deformation. This reduces the risk of slippage when the first threaded fastener is connected to the sheet metal part.

[0016] On the other hand, compared with the related technology that uses the first threaded fastener to directly screw onto the plastic connection part, and requires increasing the depth of the second through hole on the connection part to ensure that the first threaded part has a sufficiently long screwing depth, this application adopts a design of fixing sheet metal parts on the connection part, which requires the length of the second through hole on the connection part to be less than that of the related technology, thereby reducing the thickness of the connection part of the terminal board.

[0017] Furthermore, since the connecting part for fixing the sheet metal part extends along the first direction, the first through hole on the rear shell, the first threaded hole on the sheet metal part, and the second through hole on the connecting part are all correspondingly provided along the second direction. The first direction is perpendicular to the thickness direction of the display device. That is, the thickness of the connecting part is located in the thickness direction of the display device. Therefore, the design of fixing the sheet metal part on the connecting part in this application can reduce the risk of stripping of the first threaded fastener when connecting the rear shell and the terminal board, while also reducing the thickness of the connecting part of the terminal board in the second direction (the thickness direction of the display device).

[0018] As an optional implementation, the circuit board has a mounting surface facing away from the back plate, and the connection terminals are disposed on the mounting surface. The connection terminals include a plurality of terminals, which are spaced apart along a third direction. Any two adjacent connection terminals are respectively configured as a first terminal and a second terminal.

[0019] The connecting part includes:

[0020] A connecting arm is connected to the body plate and extends along the first direction. At least a portion of the projection of the connecting arm onto the mounting surface falls between the projections of the first terminal and the second terminal onto the mounting surface. Along the second direction, the distance from the surface of the connecting arm away from the rear shell to the mounting surface is greater than the thickness of the first terminal and the second terminal.

[0021] A connecting post is connected to one end of the connecting arm away from the body plate and extends in the second direction toward the circuit board. The connecting post is located on the side of the first terminal away from the clearance opening in the first direction. The connecting post is provided with a second through hole. The sheet metal part is fixed on the connecting post.

[0022] The third direction is perpendicular to both the second direction and the first direction.

[0023] If the first threaded fastener is directly screwed to the connector of the terminal board, and to ensure that the first threaded fastener does not strip, the second through hole on the connector usually needs to be made longer, giving it a longer screwing length. This increases the thickness of the connector. To further prevent interference between the connector and the connecting terminals during assembly of the terminal board and the circuit board, the connector is usually pushed in from between two adjacent connecting terminals along the first direction. However, this results in an excessive distance between adjacent terminals, which is detrimental to the compactness of the circuit board structure. In other words, to balance compactness with preventing interference between the connector and the connecting terminals, the connector needs to be raised in the second direction (the thickness direction of the display device), ensuring that the distance from the connector to the circuit board is greater than the thickness of the connecting terminal to avoid interference in the second direction. Furthermore, if the connector itself is already thick, adding the thickness of the connecting terminal further increases the thickness of the connector in the second direction, ultimately resulting in the connector of the terminal board being raised too high, thus increasing the overall thickness of the display device and hindering its thinning.

[0024] Based on the above, this application, by utilizing sheet metal parts fixed to the connecting part to reduce the risk of stripping and the thickness of the connecting part, adopts a design in which the connecting part includes a connecting arm and a connecting post. At least a portion of the projection of the connecting arm on the mounting surface falls between the projections of the first terminal and the second terminal on the mounting surface. Along the second direction, the distance from the surface of the connecting arm away from the rear shell to the mounting surface is greater than the thickness of the first terminal and the second terminal. The connecting post is located on the side of the first terminal away from the clearance opening along the first direction. That is, in this application, during the installation process of the connecting part, the connecting arm can be installed without obstructing the space between two adjacent terminals, and the connecting post can extend into the space behind the connecting terminal away from the clearance opening. This ensures that the connecting post does not occupy the space between the first terminal and the second terminal, and since the connecting arm does not occupy the space between the two terminals in the second direction, the entire connecting part does not occupy the space between the two terminals. In this way, while reducing the interference between the connecting part and the connecting terminal, the distance between any two adjacent connecting terminals can be shortened, allowing the connecting terminals on the circuit board to be set more compactly, thereby ensuring the compactness of the overall layout of the circuit board.

[0025] It can be understood that the extension of the connecting post along the second direction toward the circuit board may include: the connecting post extending into space in the thickness direction of the display device that is not shared with the connecting terminal, or extending into space in the thickness direction of the display device that is shared with the connecting terminal. In other words, the distance from the surface of the connecting post away from the rear housing to the mounting surface along the second direction is greater than or equal to or less than the thickness of the first terminal and the second terminal.

[0026] Since the sheet metal part is fixed on the connecting post, and the connection between the sheet metal part and the first threaded fastener can reduce the thickness of the connecting post itself in the second direction, in one example, even if the distance from the surface of the connecting post away from the rear shell to the mounting surface in the second direction is greater than or equal to the thickness of the first terminal and the second terminal, that is, the connecting part does not share the thickness space with the connecting terminal in the second direction, the overall thickness of the connecting part can be reduced, thereby reducing the overall thickness of the display device.

[0027] In another example, since the connecting post extends towards the circuit board in the second direction, and the distance from the surface of the connecting post away from the rear cover to the mounting surface in the second direction is less than the thickness of the first and second terminals, that is, in the thickness direction of the display device, the thickness of the connecting post is greater than the thickness of the connecting arm. The thinner connecting arm is located above the connecting terminal, which does not occupy the space between the connecting terminals and does not increase the thickness of the connection. The connecting post and the connecting terminal share a portion of the space in the thickness direction of the display device, thereby allowing the connecting post to not occupy additional space in the thickness direction of the display device. This effectively avoids the connection part of the terminal board being raised too high in the second direction, resulting in a better overall thickness reduction effect for the display device, which is conducive to achieving a thinner display device. Furthermore, in this example, even if there is temporary thickness interference between the connecting post and the connecting terminal during the installation process, since the overall thickness of the connection part is reduced, the space behind the connecting post away from the clearance opening can be offset from the connecting terminal in the first direction after assembly without interference, thus facilitating the assembly of the terminal board.

[0028] As an alternative implementation, the dimension of the connecting post in the second direction is 3mm to 6mm.

[0029] If the connecting post is too large in the second direction, resulting in excessive thickness, the length of the connecting post extending towards the circuit board in the second direction will be too long. This will cause excessive interference between the connecting post and the connecting terminal in the second direction, making it difficult to push the connecting post between two adjacent connecting terminals in the second direction, thus affecting the assembly of the terminal board. Furthermore, while maintaining a sufficient distance between the connecting post and the circuit board, it will cause the entire connecting part in the second direction to be raised, which is not conducive to reducing the thickness of the display device. If the connecting post is too small in the second direction, resulting in excessive thickness, it will not only affect the structural strength of the connecting post and make it prone to deformation, failing to ensure the stability of the sheet metal fixing, but may also cause the depth of the second through hole to be too shallow. After the first threaded fastener is installed, the bottom of the first threaded fastener will be excessively exposed outside the second through hole, increasing the risk of short circuit when the first threaded fastener contacts the circuit board.

[0030] Therefore, by limiting the size of the connecting post in the second direction, this application can control the thickness of the connecting post within a reasonable range. This avoids excessive thickness of the connecting post, which would reduce interference between the connecting post of the terminal board and the circuit board during installation and is more conducive to the thinning of the display device. At the same time, it also avoids excessive thickness of the connecting post, which would better ensure that the connecting post of the terminal board has sufficient structural strength. Furthermore, without changing the length of the first threaded fastener, it can also avoid the first threaded fastener being excessively exposed outside the connecting post, thereby better avoiding or reducing the risk of short circuits caused by the first threaded fastener being exposed outside and contacting components on the circuit board.

[0031] In one optional embodiment, the connecting portion has a first surface and a second surface disposed opposite to each other along the second direction, and the second through hole extends from the first surface to the second surface;

[0032] The sheet metal parts include:

[0033] The main body is disposed on the first surface and has the first threaded hole.

[0034] The extension is provided on both sides of the main body along the radial direction of the first threaded hole. The extension extends along the second direction, and one end of the extension away from the main body is connected to the second surface to fix the main body to the connecting part.

[0035] In this application, a sheet metal part is designed including a main body and an extension. The main body for connection with the first threaded fastener is provided on the first surface, and extensions are provided on both sides of the main body. The extensions extend along the second direction (the thickness direction of the display device). This arrangement allows the extensions on both sides of the main body to extend in the second direction and cover the connecting part. The main body is fixed to the connecting part by fixing the extensions to the second surface. Since the main body is provided on the first surface and the extensions are connected to the second surface, the terminal board can provide support for the sheet metal part on both surfaces along the second direction, thereby making the fixing method between the sheet metal part and the connecting part more stable and reliable.

[0036] It is understood that the extension extends along the second direction, and the end of the extension away from the main body is connected to the second surface. This extension is equivalent to the fixing part of the sheet metal part. That is, the main body is fixed to the connecting part by connecting the extension with the connecting part. Compared with the extension extending along the first direction or along other directions, the extension extending along the second direction can make the overall structure of the sheet metal part more compact. It can avoid the situation where the extension extends along other directions, and in order to realize the connection between the extension and the connecting part, the connecting part needs to increase the size in other directions. In this way, it can avoid the problem that the connecting part will interfere with the connecting terminal due to excessive size.

[0037] As an optional implementation, the first surface is provided with a through hole extending to the second surface, the extension is provided through the through hole, and one end of the extension away from the main body extends out of the through hole and is bent to form a hook.

[0038] By providing a through hole extending to the second surface on the first surface of the connecting part for the extension to pass through, and bending the end of the extension to form a hook, the hook and the second surface can cooperate to form a limit in the axial direction (second direction) of the third through hole, restricting the sheet metal part from coming out of the through hole in the second direction. While achieving a stable connection between the sheet metal part and the terminal board, the sheet metal part is fixed to the connecting part by bending to form a hook. That is, the sheet metal part uses its own structural deformation to achieve a fixed connection with the terminal board. In this way, there is no need to set additional positioning or locking structures on the terminal board and the sheet metal part, simplifying the structure of the terminal board and the sheet metal part, saving mold costs, and making the forming of the terminal board and the sheet metal part more convenient.

[0039] Furthermore, by using a perforation to allow the extension to pass through, and with the perforation being made inside the sheet metal part, the extension of the sheet metal part can be embedded inside the terminal plate, and the outer periphery of the extension can be effectively constrained, thereby making the connection of the sheet metal part more robust and thus enhancing the reliability of the sheet metal part connection.

[0040] In addition, by embedding sheet metal parts inside the terminal board, the structure of the terminal board can be strengthened, making it less prone to deformation.

[0041] In one optional embodiment, the second surface is provided with a first groove, the second through hole and the perforation are both connected to the first groove, the hook is located in the first groove, and the hook can abut against the bottom wall of the first groove; and / or,

[0042] The end of the extension away from the main body is bent toward the second through hole to form the hook, and the hook is inclined toward the main body.

[0043] By providing a first groove on the second surface of the connecting part, both the second through hole and the perforation are located within the first groove. The hook is positioned within this first groove and abuts against the bottom wall of the groove. That is, after the end of the extension away from the main body passes through the perforation, it can be bent into the first groove. This design ensures a stable connection between the sheet metal part and the terminal board while preventing the hook from protruding from the second surface and occupying unnecessary space. This avoids the problem of increased thickness in the connecting part due to the hook extending beyond its surface. Furthermore, when the second surface is close to the circuit board, since the sheet metal part is metal, this design prevents the metal hook from protruding from the second surface, thus avoiding the risk of short circuits caused by contact between the hook and components on the circuit board.

[0044] By bending the end of the extension away from the main body towards the second through hole, and making the hook inclined towards the main body, the hook has a barbed structure relative to the extension. This design allows the hook to disperse the force more effectively when subjected to external force, reducing concentrated stress in a single direction and lowering the risk of deformation. This makes it more difficult for the sheet metal part to detach from the through hole, thus improving the stability of the sheet metal connection. Furthermore, bending the end of the extension away from the main body towards the second through hole, i.e., bending the hook towards the axis of the first threaded hole in an inward-contracting manner rather than outward-opening shape, results in a smaller overall volume of the sheet metal part. This prevents it from occupying extra space in the connection portion of the terminal board, allowing the connection portion to maintain a structure that is essentially free of sheet metal even when it is fixed with it, thus keeping the overall dimensions of the connection portion unchanged.

[0045] As an optional implementation, the connecting portion further has an outer peripheral surface, which is connected between the first surface and the second surface;

[0046] The extension covers at least a portion of the outer peripheral surface, and the end of the extension away from the main body can be bent to form a hook, which abuts against the second surface.

[0047] The extension covers at least a portion of the outer peripheral surface of the terminal block and is bent to form a hook that abuts against the second surface. This external assembly method simplifies assembly and improves the efficiency of sheet metal assembly, while ensuring the hook abuts against the connecting portion to prevent detachment. Furthermore, by covering at least a portion of the outer peripheral surface of the terminal block, the structural strength of the connection area is enhanced, improving the structural mechanical properties of the terminal block and making it less prone to deformation.

[0048] As an optional implementation, the surface of the connecting portion is provided with a second groove, and at least a portion of the sheet metal part is accommodated in the second groove; and / or,

[0049] The depth of the first threaded hole is 1mm to 1.4mm.

[0050] By providing a second groove on the surface of the connector of the terminal board, at least a portion of the sheet metal part is accommodated in the second groove. This allows the sheet metal part to utilize the space on the connector of the terminal board without occupying excess space on the connector along the second direction or reducing the space occupied in the second direction. In other words, the method of fixing the sheet metal part to the connector in this application can utilize a portion of the structural space on the connector without excessively increasing the space occupied in the thickness direction of the display device. This ensures that even if the connector is fixed with a sheet metal part, the volume of the connector will not increase excessively, thereby better controlling the reduction of the thickness of the connector in the second direction. Furthermore, it is more conducive to the compact design of the internal structure of the display device, and further facilitates the reduction of the overall thickness of the display device.

[0051] This application uses a first threaded fastener to fix the rear shell to the sheet metal part, thereby connecting the rear shell to the terminal board. Since the sheet metal part is metal, the first threaded fastener is not directly screwed into the plastic connection part. Because the metal sheet metal part has a high coefficient of friction and high hardness, it is not easily deformed, making it less prone to slippage when the first threaded fastener is connected to the sheet metal part. Therefore, a shorter screw length can ensure a reliable connection of the first threaded fastener. If the depth of the second threaded hole is less than 1mm, the depth is too shallow, resulting in a short length of sheet metal part involved in the screwing. Even if the first threaded fastener is connected to the metal sheet metal part, it may easily come out of the first threaded hole, which is detrimental to the stability of the connection. If the depth of the second threaded hole is greater than 1.4mm, the depth is too deep, which makes the length of the sheet metal part involved in the screw connection too long. During the assembly of the first threaded fastener, the rotation time in the second threaded hole is too long, which is not conducive to improving the assembly efficiency. In addition, if the depth of the first threaded hole is too long, it will cause the thickness of the part of the sheet metal part where the first threaded hole is set to be too thick. When the sheet metal part is fixed on the connecting part, it will cause the overall thickness of the connecting part to increase.

[0052] Therefore, by setting the depth of the first threaded hole within a reasonable range, the depth of the first threaded hole is not too shallow, which would affect the reliability of the screw connection, thus enabling a reliable connection between the rear shell and the terminal plate. At the same time, the depth of the first threaded hole is not too deep, which would prevent the first threaded fastener from rotating in the first threaded hole for too long during assembly, thereby improving assembly efficiency and preventing the thickening of the sheet metal parts from causing an increase in the thickness of the connection.

[0053] As an optional implementation, the sheet metal part is provided with a protrusion protruding along the second direction, the protrusion being at least partially located in the second through hole, and the protrusion being provided with the first threaded hole.

[0054] By providing a protrusion protruding in the second direction on the sheet metal part, and providing a first threaded hole on the protrusion, and making the protrusion at least partially located in the second through hole, that is, the first threaded hole is formed by the structure of the connecting part itself, and the first threaded hole is provided in the space where the second through hole is located. With this configuration, under the premise that the first threaded fastener can be connected to the sheet metal part to achieve a reliable connection between the rear shell and the terminal plate, the first threaded hole and the second through hole can also be reused in space, so as not to occupy the space of the first threaded hole in the second direction. This makes the overall thickness of the connecting part with the sheet metal part fixed in the second direction smaller, which can avoid or reduce the risk of interference with the connecting terminal caused by the excessive thickness of the terminal plate in the second direction. Furthermore, by using the design of the protrusion in the second through hole, the thickness of the display device can be further reduced.

[0055] Furthermore, by providing at least a portion of the protrusion in the second through hole of the connecting part, the inner wall surface of the connecting part used to surround the second through hole can provide a certain limiting effect on the circumference of the protrusion. That is, the second through hole of the connecting part can be used to form a certain pre-fixing and constraint effect on the sheet metal part, which is more conducive to the assembly of the sheet metal part and improves the stability of the sheet metal part fixing.

[0056] As an optional implementation, the back plate is provided with a second threaded hole, and the rear shell is also provided with a third through hole. The rear shell is connected to the second threaded hole by a second threaded fastener passing through the third through hole, so that the rear shell is connected to the back plate.

[0057] The second threaded fastener and the first threaded fastener are configured with the same fastening structure.

[0058] This application establishes a second threaded hole on the back plate and a third through hole on the rear shell, using a second threaded fastener to connect the rear shell to the back plate. Furthermore, the first threaded fasteners used to connect the rear shell to the terminal board and to the back plate are of the same specification. This allows for the use of the same type of threaded fastener during rear shell assembly, reducing the number of types of fasteners used on the rear shell. Using only one type reduces or avoids the inefficiency caused by mixing or using the wrong type of fastener, thus standardizing the use of threaded fasteners on the rear shell and improving assembly efficiency.

[0059] Compared with the prior art, the beneficial effects of this application are:

[0060] In the display device provided in this application, the terminal board's connecting portion serves as the part connected to the rear housing. Since this connecting portion is made of plastic, if a first threaded fastener is directly threaded through the first through-hole on the rear housing and screwed into the connecting portion, the connecting portion may slip during rotation due to its low coefficient of friction or susceptibility to deformation, leading to stripping of the threads. To solve this stripping problem, increasing the depth of the second through-hole to increase the threaded length of the first threaded fastener connection would increase the thickness of the connecting portion, hindering the overall thickness reduction of the terminal board.

[0061] Based on this, this application fixes a sheet metal part to the connecting part of the terminal board. On one hand, a first threaded hole is formed on the sheet metal part, and simultaneously, the first through hole on the rear shell, the first threaded hole on the sheet metal part, and the second through hole on the connecting part are correspondingly arranged along a second direction. This allows a first threaded fastener to be threaded through the first through hole and the first threaded hole, thus achieving a threaded connection between the rear shell and the sheet metal part. Since the sheet metal part is fixed to the connecting part, the terminal board can be connected to the rear shell via the sheet metal part. In other words, in this application, the sheet metal part fixing the connecting part of the terminal board allows the first threaded fastener to be threaded onto the sheet metal part. Because the sheet metal part is made of metal, it has a high coefficient of friction and high hardness, making it less prone to deformation. This reduces the risk of slippage when the first threaded fastener is connected to the sheet metal part.

[0062] On the other hand, compared with the related technology that uses the first threaded fastener to directly screw onto the plastic connection part, and requires increasing the depth of the second through hole on the connection part to ensure that the first threaded part has a sufficiently long screwing depth, this application adopts a design of fixing sheet metal parts on the connection part, which requires the length of the second through hole on the connection part to be less than that of the related technology, thereby reducing the thickness of the connection part of the terminal board.

[0063] Furthermore, since the connecting part for fixing the sheet metal part extends along the first direction, the first through hole on the rear shell, the first threaded hole on the sheet metal part, and the second through hole on the connecting part are all correspondingly provided along the second direction. The first direction is perpendicular to the thickness direction of the display device. That is, the thickness of the connecting part is located in the thickness direction of the display device. Therefore, the design of fixing the sheet metal part on the connecting part in this application can reduce the risk of stripping of the first threaded fastener when connecting the rear shell and the terminal board, while also reducing the thickness of the connecting part of the terminal board in the second direction (the thickness direction of the display device).

[0085] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0086] Please refer to the following: Figure 1 and Figure 2 This application discloses a display device 100, which may include, but is not limited to, 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.

[0087] In some embodiments, the display device 100 includes a display module 10 for displaying image information.

[0088] Taking a television set as an example, the display module 10 may include a display screen, which may include a display panel, a light source, and an optical film assembly (not shown). The light source, the optical film assembly, and the display panel are arranged sequentially from back to front. The light emitted by the light source is projected onto the display panel after passing through the optical film assembly, thereby displaying image information on the display panel.

[0089] In some embodiments, the display device 100 includes a back plate 20. The back plate 20 is located behind the display module 10. As the main support structure of the display device 100, the back plate 20 is typically made of metal to provide effective support for the display device 100.

[0090] In some embodiments, the display device 100 includes a rear cover 30. The rear cover 30 is connected to the back plate 20. The rear cover 30 is detachable from the back plate 20, and can be used to protect the internal components of the display device 100. Typically, the rear cover 30 serves as an exterior component of the display device 100 and is often made of plastic to achieve both portability and a good appearance.

[0091] In order to connect the back plate 20 and the rear shell 30, in some embodiments, the back plate 20 is provided with a second threaded hole 20a.

[0092] Combination Figure 2 In some embodiments, the rear shell 30 is provided with a third through hole 30a, and the rear shell 30 is connected to the second threaded hole 20a by a second threaded fastener 30b passing through the third through hole 30a, so that the rear shell 30 is connected to the back plate 20.

[0093] Optionally, there can be multiple third through holes 30a, which are spaced apart on the rear shell 30. Correspondingly, there are also multiple second threaded holes 20a, which are respectively arranged in one-to-one correspondence with multiple third through holes 30a. Each third through hole 30a and each second threaded hole 20a are connected by a second threaded fastener 30b to achieve a reliable connection between the rear shell 30 and the back plate 20.

[0094] Of course, in some other embodiments, the back cover 30 can also be connected to the back plate 20 by other means such as snap-fit ​​or adhesive, which can also serve the purpose of connection.

[0095] In some embodiments, the rear housing 30 is provided with a first through hole 30c. The first through hole 30c is spaced apart from the third through hole 30a.

[0096] Please refer to the following: Figures 2 to 4 In some embodiments, the rear cover 30 is provided with an opening 30d. Optionally, the opening 30d can be elongated, such as a rectangular opening 30d or an opening 30d with rounded ends and a square shape in the middle.

[0097] In some embodiments, the display device 100 includes a circuit board 40. The circuit board 40, as a core component inside the display device 100, may include a motherboard, a power board, an audio board, a backlight board, and an input / output board, etc., for controlling the display device 100 and outputting relevant operation commands accordingly.

[0098] In some embodiments, the circuit board 40 is fixed to the side of the back plate 20 facing the rear shell 30, and the circuit board 40 is provided with a connection terminal 40a, which is provided corresponding to the opening 30d.

[0099] It is understood that the circuit board 40 has a mounting surface 401 facing away from the back plate 20, and connection terminals 40a are disposed on the mounting surface 401 of the circuit board 40. The number of connection terminals 40a includes multiple terminals, which are spaced apart and used to connect to external devices with different functions.

[0100] Combination Figure 3 and Figure 4 In some embodiments, the display device 100 includes a terminal plate 50, which may be disposed at the opening 30d to prevent the internal circuit board 40 from being exposed. The terminal plate 50 has a clearance opening 50a at the position corresponding to the connection terminal 40a to avoid the connection terminal 40a.

[0101] In some embodiments, the connection terminal 40a may extend out of the rear housing 30 through the opening 30d, or may not extend out of the rear housing 30, and the wiring terminal of the external device is connected to the connection terminal 40a through the clearance opening 50a.

[0102] To maximize the use of the opening 30d area on the rear housing 30 and reduce the wasted area of ​​the circuit board 40, this opening 30d area is unsupported. Furthermore, the rear housing 30 is typically made of plastic, which is prone to deformation. Therefore, a fixing mechanism is needed between the terminal board 50 and the rear housing 30. To reduce costs, the terminal board 50 is usually made of plastic, and self-tapping screws are typically used when screwing the terminal board 50 to the rear housing 30, which is prone to stripping.

[0103] To solve the above problems, combined with Figure 4 As shown, in some embodiments, the terminal plate 50 is provided with a second through hole 50b, which is disposed in a second direction X corresponding to the first through hole 30c.

[0104] It can be understood that both the second through hole 50b and the first through hole 30c are opened along the second direction X, that is, the second direction X is the axial direction of the first through hole 30c and the second through hole 50b.

[0105] Combination Figure 5 and Figure 6 In some embodiments, the terminal board 50 includes a body board portion 51, which is connected to the circuit board 40 and located in the opening 30d.

[0106] The main body plate 51 has a clearance opening 50a at the position corresponding to the connection terminal 40a.

[0107] It should be noted that the back cover 30 has an opening 30d with a certain depth, which is the wall thickness of the back cover 30. This allows the opening 30d to have an external side and a side facing the circuit board 40. The main body plate 51 can be located on the side of the opening 30d facing the circuit board 40, that is, within the space formed by the back cover 30 and the circuit board 40, or it can be on the external side of the opening 30d, or it can be located in the opening 30d.

[0108] In some embodiments, the terminal block 50 includes a connecting portion 52, which may be made of plastic.

[0109] In some embodiments, the connecting portion 52 is connected to the body plate portion 51 and extends along the first direction Y. The connecting portion 52 is provided with a second through hole 50b, which is disposed in accordance with the first through hole 30c along the second direction X.

[0110] Wherein, the first direction Y is perpendicular to the second direction X, and the second direction X is the thickness direction of the display device 100. It can be understood that the second direction X can be the front-back direction of the display device 100, and the first threaded fastener 60b is installed along the thickness direction of the display device 100.

[0111] In some embodiments, the terminal block 50 includes a sheet metal part 60, which is fixed to the connecting portion 52. It is understood that the sheet metal part 60 is fixed to the terminal block 50 by some connection method, the specific fixing method of which will be described in detail below.

[0112] In some embodiments, the sheet metal part 60 is provided with a first threaded hole 60a, and the first threaded hole 60a is provided in a second direction X corresponding to the second through hole 50b.

[0113] In some embodiments, the display device 100 includes a first threaded fastener 60b. The rear housing 30 is screwed to the first threaded hole 60a through the first threaded fastener 60b, so that the connecting part 52 and the sheet metal part 60 are both connected to the rear housing 30, thereby realizing the connection between the terminal plate 50 and the rear housing 30.

[0114] It should be noted that after the first threaded fastener 60b is assembled, at least the part of the first threaded fastener 60b that does not participate in the screwing is located in the second through hole 50b. That is, the part of the first threaded fastener 60b that does not participate in the screwing is not completely exposed outside the terminal plate 50. This can avoid excessive exposure of the first threaded fastener 60b and avoid or reduce the risk of interference or short circuit between the first threaded fastener 60b and the devices on the circuit board 40.

[0115] It is worth noting that the first through hole 30c and the third through hole 30a on the rear shell 30 can be plain holes, that is, no threaded structure is formed on the inner wall surface of the first through hole 30c and the third through hole 30a. It can be understood that in this case, the inner diameter of the first through hole 30c and the third through hole 30a will be larger than the outer diameter of the corresponding threaded fastener. Alternatively, the first through hole 30c and the third through hole 30a can also be plain holes before the threaded fastener is installed, but a threaded structure is formed after the threaded fastener is installed. Alternatively, other forms are also possible, as long as the threaded fastener passes through to achieve the fixation of the rear shell 30 to the terminal plate 50 and the back plate 20. The specific form is not limited in the embodiments of this application.

[0116] It is understandable that the body plate 51 and the connecting part 52 can be made of the same material, namely plastic. Of course, they can also be made of different materials; for example, the connecting part 52 can be made of plastic, while the body plate 51 can be made of non-plastic materials, such as metal or composite materials. Furthermore, the body plate 51 and the connecting part 52 can be separate or integrally formed.

[0117] Preferably, the body plate portion 51 and the connecting portion 52 are integrally formed and are both made of plastic. The plastic can be flame-retardant ABS (Acrylonitrile Butadiene Styrene) or flame-retardant PC-ABS (Polycarbonate-Acrylonitrile Butadiene Styrene) material.

[0118] It should be noted that the opening 30d on the rear shell 30 in this application is oriented along the first direction Y, that is, the opening 30d can be oriented along the height or width direction of the display device 100. Since the second direction X is the thickness direction of the display device 100, and the first direction Y is perpendicular to the second direction X, the main body plate 51 and the connecting part 52 are arranged approximately perpendicularly, and the connecting part 52 is located between the circuit board 40 and the rear shell 30 along the thickness direction of the display device 100.

[0119] In the display device 100 provided in this application, the connecting portion 52 of the terminal plate 50 serves as the part connected to the rear housing 30. Since the material of the connecting portion 52 is plastic, if the first threaded fastener 60b is directly screwed into the connecting portion 52 through the first through hole on the rear housing 30, the connecting portion 52 may slip during rotation due to its low coefficient of friction or easy deformation, thus easily causing stripping of the threads. To solve the stripping problem, increasing the depth of the second through hole 50b to increase the screwing length of the first threaded fastener 60b would increase the thickness of the connecting portion 52, which is not conducive to reducing the overall thickness of the terminal plate 50.

[0120] Based on this, this application fixes a sheet metal part 60 to the connecting portion 52 of the terminal plate 50. On the one hand, a first threaded hole 60a is formed on the sheet metal part 60, and the first through hole on the rear shell 30, the first threaded hole 60a on the sheet metal part 60, and the second through hole 50b on the connecting portion 52 are correspondingly arranged along the second direction X. This allows the first threaded fastener 60b to be threaded through the first through hole and the first threaded hole 60a, thereby achieving the threaded connection between the rear shell 30 and the sheet metal part 60. Since the sheet metal part 60 is fixed on the connecting portion 52, the terminal plate 50 can be connected to the rear shell 30 through the sheet metal part 60. That is, in this application, the sheet metal part 60 of the connecting part 52 of the fixed terminal plate 50 can be used to make the first threaded fastener 60b screwed to the sheet metal part 60. Since the sheet metal part 60 made of metal has a high coefficient of friction and high hardness, it is not easy to deform. This makes it less likely for the first threaded fastener 60b to slip when connected to the sheet metal part 60, thereby reducing the risk of stripping.

[0121] On the other hand, compared with the related technology, which uses the first threaded fastener 60b to directly screw onto the plastic connecting part 52, and requires increasing the depth of the second through hole 50b on the connecting part 52 to ensure that the first threaded part has a sufficiently long screwing depth, this application adopts a design of fixing the sheet metal part 60 on the connecting part 52. The length requirement of the second through hole 50b on the connecting part 52 is less than that of the related technology, thereby reducing the thickness of the connecting part 52 of the terminal board 50.

[0122] Furthermore, since the connecting portion 52 for fixing the sheet metal part 60 extends along the first direction Y, the first through hole on the rear shell 30, the first threaded hole 60a on the sheet metal part 60, and the second through hole 50b on the connecting portion 52 are all correspondingly provided along the second direction X. The first direction Y is perpendicular to the thickness direction of the display device 100, that is, the thickness of the connecting portion 52 is located in the thickness direction of the display device 100. Therefore, the design of fixing the sheet metal part 60 on the connecting portion 52 in this application can reduce the risk of stripping of the first threaded fastener 60b when connecting the rear shell 30 and the terminal plate 50, and at the same time reduce the thickness of the connecting portion 52 of the terminal plate 50 in the second direction X (the thickness direction of the display device 100).

[0123] It is understandable that by using sheet metal parts 60 to fix the terminal block 50 to the connecting part 52, the thickness of the connecting part 52 of the terminal block 50 can be reduced. In this way, while ensuring that the connecting part 52 maintains a non-interfering distance with the circuit board 40 in the second direction X, the overall size of the terminal block 50 in the thickness direction of the display device 100 is smaller, thereby reducing the thickness of the display device 100 and achieving a thinner display device 100.

[0124] In some embodiments, the second threaded fastener 30b and the first threaded fastener 60b are configured with the same fastening structure. It should be noted that the same fastening structure means that the second threaded fastener 30b and the first threaded fastener 60b use threaded fasteners of the same specification, such as M3, M4 or M5.

[0125] This application provides a second threaded hole 20a on the back plate 20 and a third through hole 30a on the rear shell 30. A second threaded fastener 30b is used to connect the rear shell 30 to the back plate 20. The first threaded fastener 60b used to connect the rear shell 30 to the terminal plate 50 and the rear shell 30 to the back plate 20 are both of the same specification. This allows for the use of the same specification of threaded fasteners during the assembly of the rear shell 30, reducing the number of types of threaded fasteners used on the rear shell 30. Using only one type reduces or avoids the inefficiency caused by mixing or using the wrong type of threaded fastener, thus standardizing the use of threaded fasteners on the rear shell 30 and improving the assembly efficiency of the rear shell 30.

[0126] Optionally, the second threaded fastener 30b and the first threaded fastener 60b can be bolts, screws, or studs, as long as they can achieve threaded connection with threaded holes and threaded structures.

[0127] Preferably, the second threaded fastener 30b and the first threaded fastener 60b are both M-series screws of the same specification, such as M3 machine screws. In this way, a sheet metal part 60 is added to the terminal plate 50, and the first threaded hole 60a of the sheet metal part 60 is used to make the terminal plate 50 and the back plate 20, which is usually metal, form a unified screw connection. This allows the threaded fasteners connecting the terminal plate 50 to the rear shell 30 and the back plate 20 to the rear shell 30 to use the same specification, breaking the current situation of mixing self-tapping screws and machine screws, and realizing the consistency of screws used on the rear shell 30.

[0128] To achieve pre-fixation between the terminal block 50 and the circuit board 40, in some embodiments, see [reference needed]. Figure 5 The terminal board 50 is provided with a buckle 50c, and correspondingly, the circuit board 40 is provided with a slot 40b. The terminal board 50 is engaged with the slot 40b through the buckle 50c to achieve a fixed connection with the circuit board 40.

[0129] Optionally, the number of clips 50c can be multiple, such as two, three, or four, with the multiple clips 50c spaced apart along the extension direction of the terminal plate 50. Preferably, the number of clips 50c is two, with the two clips 50c located at opposite ends of the terminal plate 50 along its length. This ensures a stable connection between the terminal plate 50 and the circuit board 40, and also prevents the connection position of the clips 50c and the slots 40b from affecting the layout of the connecting terminals 40a.

[0130] Specifically, the main body plate 51 is provided with a buckle 50c, which engages with the slot 40b to achieve a fixed connection with the circuit board 40. Buckles 50c are provided at both ends of the main body plate 51 along its length.

[0131] In some embodiments, the opening 30d is oriented along the first direction Y. Since the rear housing 30 has a connection terminal 40a at the opening 30d, the interface orientation of the connection terminal 40a is also oriented along the first direction Y.

[0132] When an external device is connected to the interface of the connection terminal 40a, the terminal of the external device can also be inserted along the first direction Y. Since the first direction Y is configured to be perpendicular to the thickness direction of the display device 100, the terminal of the external device will not protrude excessively on the back cover 30 along the thickness direction of the display device 100, and the cable connected to the terminal of the external device can be attached to the surface of the back cover 30, making the appearance of the display device 100 better.

[0133] The opening 30d on the rear cover 30 is oriented along the first direction Y, and the main body plate 51 of the terminal board 50 is positioned on the side where the opening 30d faces the circuit board 40. The second direction X is configured to be the thickness direction of the display device 100, and the first direction Y is perpendicular to the second direction X. That is, the opening 30d on the rear cover 30 is not in the thickness direction of the display device 100. The mounting direction of the terminal board 50 and the circuit board 40 is along the first direction Y, and the mounting direction of the first threaded fastener 60b is along the second direction X (the thickness direction of the display device 100). This allows the opening 30d to be concealed to a certain extent, improving the appearance. Simultaneously, the sheet metal part 60 is mounted using the connecting portion 52 that connects to the main body plate 51 along the first direction Y, connecting to the rear cover 30. This allows the first threaded fastener 60b to be mounted along the thickness direction of the display device 100. Compared to the mounting direction along the first direction Y, this mounting direction provides more operating space and makes assembly more convenient.

[0134] It should be noted that the main body plate 51 is a long strip-shaped plate structure, and its length extension direction is consistent with the extension direction of the opening 30d. The connecting part 52 can be a columnar structure, a block structure, etc., as long as it can be provided for the sheet metal part 60. The specific structural form is not limited in this embodiment.

[0135] For ease of understanding, this application uses the following example: the thickness direction of the display device 100 is defined as the second direction X, the height direction of the display device 100 is defined as the first direction Y, and the width direction of the display device 100 is defined as the third direction Z. The third direction Z is perpendicular to both the second direction X and the first direction Y. Thus, the opening 30d of the rear shell 30 faces the height direction (first direction Y) of the display device 100, and the opening 30d of the rear shell 30 extends along the width direction (third direction Z) of the display device 100. Therefore, the terminal plate 50 extends entirely along the third direction Z. The first threaded fastener 60b passes through the first through hole 30c and connects to the first threaded hole 60a along the thickness direction (second direction X) of the display device 100.

[0136] If the first threaded fastener 60b is directly screwed to the connecting portion 52 of the terminal plate 50, and to ensure that the first threaded fastener 60b does not strip, the second through hole 50b on the connecting portion 52 usually needs to be made longer to provide sufficient screwing length, which would increase the thickness of the connecting portion 52. Furthermore, to further prevent interference between the connecting portion 52 and the connecting terminal 40a during assembly of the terminal plate 50 and the circuit board 40, the connecting portion 52 is usually pushed in from between two adjacent connecting terminals 40a along the first direction Y. This would result in an excessively large distance between the two adjacent terminals, which is detrimental to the structural compactness of the circuit board 40. In other words, if compactness is desired while simultaneously avoiding interference between the connecting portion 52 and the connecting terminal 40a, then the connecting portion 52 needs to be raised in the second direction X (the thickness direction of the display device 100) so that the distance from the connecting portion 52 to the circuit board 40 is greater than the thickness of the connecting terminal 40a, thus preventing interference with the connecting terminal 40a in the second direction X. Based on this, if the connecting part 52 itself has a relatively thick thickness, and then the thickness of the connecting terminal 40a is added, the connecting part 52 of the terminal board 50 will eventually be raised too high in the second direction X, thereby increasing the overall thickness of the display device 100, which is not conducive to the thinning of the display device 100.

[0137] Based on the above, see Figures 5 to 8 In some embodiments, the connection terminals 40a include multiple terminals, which are spaced apart along a third direction Z. Any two adjacent connection terminals 40a are respectively configured as a first terminal 40a1 and a second terminal 40a2.

[0138] In some embodiments, the connecting portion 52 includes a connecting arm 521, which is connected to the body plate portion 51 and extends along the first direction Y.

[0139] In some embodiments, at least a portion of the projection of the connecting arm 521 onto the plane of the circuit board 40 falls between the projections of the first terminal 40a1 and the second terminal 40a2 onto the plane of the circuit board 40. In other words, at least a portion of the projection of the connecting arm 521 onto the mounting surface 401 falls between the projections of the first terminal 40a1 and the second terminal 40a2 onto the mounting surface 401.

[0140] Combination Figure 8 , Figure 8 It indicates Figure 3 The schematic diagram of a partial structure of the display device is a cross-sectional view along the first direction Y through the first threaded fastener 60b. In some embodiments, along the second direction, the distance h1 from the surface of the connecting arm 521 facing away from the rear housing 30 to the mounting surface 401 is greater than the thickness T of the first terminal 40a1 and the second terminal 40a2. In other words, the connecting arm 521 is spaced apart from the first terminal 40a1 and the second terminal 40a2 in the second direction X. A certain gap is also maintained between the connecting arm 521 and the first terminal 40a1 and the second terminal 40a2 in the second direction X.

[0141] It is understood that at least a portion of the projection of the connecting arm 521 onto the plane of the circuit board 40 falls between the projections of the first terminal 40a1 and the second terminal 40a2 onto the plane of the circuit board 40. Along the second direction, the distance from the surface of the connecting arm away from the rear housing to the mounting surface 401 is greater than the thickness of the first and second terminals. That is, in the third direction Z, at least a portion of the connecting arm 521 is located between the first terminal 40a1 and the second terminal 40a2. In the second direction X, the connecting arm 521 does not interfere with the first terminal 40a1 and the second terminal 40a2. For example, along the second direction X, one side of the connecting arm 521 in the third direction Z is located above the first terminal 40a1, and the other side of the connecting arm 521 in the third direction Z is located above the second terminal 40a2. This allows the connecting arm 521 to be positioned above the space between the first terminal 40a1 and the second terminal 40a2, enabling the connecting portion 52 to be assembled between the two terminals.

[0142] Optionally, the connecting arm 521 is a thin plate-like structure such as a square or triangular shape.

[0143] In some embodiments, the connecting portion 52 includes a connecting post 522, which is connected to the end of the connecting arm 521 away from the body plate and extends in the second direction X toward the circuit board 40. The connecting post 522 is provided with a second through hole 50b, and the sheet metal part 60 is fixed to the connecting post 522.

[0144] In some embodiments, combined with Figure 7 The connecting post 522 is located on the side of the first terminal 40a1 away from the clearance opening along the first direction Y. That is, the connecting post 522 can extend into the space behind the connecting terminal 40a away from the clearance opening.

[0145] In some embodiments, the connecting post 522 is provided with a second through hole 50b, and the sheet metal part 60 is fixed on the connecting post 522.

[0146] It can be understood that the extension of the connecting post 522 along the second direction X toward the circuit board 40 may include: the connecting post 522 extending into a space in the thickness direction of the display device 100 that does not share the same thickness as the connecting terminal 40a, or extending into a space in the thickness direction of the display device 100 that shares the same thickness as the connecting terminal 40a. In other words, the distance from the surface of the connecting post 522 facing away from the rear housing 30 to the mounting surface 401 along the second direction X is greater than or equal to or less than the thickness of the first terminal 40a1 and the second terminal 40a2.

[0147] In other words, along the second direction X, the distance h2 from the surface of the connecting post 522 away from the rear housing 30 to the mounting surface 401 is greater than or equal to or less than the thickness T of the first terminal 40a1 and the second terminal 40a2.

[0148] It is understandable that in the first example, the distance from the surface of the connecting post 522 facing away from the rear housing 30 along the second direction X to the mounting surface 401 is greater than the thickness of the first terminal 40a1 and the second terminal 40a2. That is, the connecting post 522 does not share a thickness space with the connecting terminal 40a in the second direction X, and the connecting part 52 is located entirely above the connecting terminal 40a (refer to...). Figure 7 (The top and bottom directions of the paper).

[0149] In the second example, the distance from the surface of the connecting post 522 away from the rear housing 30 along the second direction X to the mounting surface 401 is equal to the thickness of the first terminal 40a1 and the second terminal 40a2. That is, the connecting post 522 does not share the thickness space with the connecting terminal 40a in the second direction X, and the surface of the connecting post 522 away from the rear housing 30 is approximately flush with the surfaces of the first terminal 40a1 and the second terminal 40a2 facing the rear housing 30.

[0150] Since the sheet metal part is fixed on the connecting column, and the connection between the sheet metal part and the first threaded fastener can reduce the thickness of the connecting column itself in the second direction, in the two examples above, the overall thickness of the connecting part can also be reduced, thereby reducing the overall thickness of the display device.

[0151] In the third example, the distance from the surface of the connecting post 522 facing away from the rear housing 30 along the second direction X to the mounting surface 401 is less than the thickness of the first terminal 40a1 and the second terminal 40a2. In this example, at least a portion of the projection of the connecting post 522 onto the plane perpendicular to the first direction Y falls on the projection of the first terminal 40a1 or the second terminal 40a2 onto the plane perpendicular to the first direction Y. In the thickness direction of the display device 100, the thickness of the connecting post 522 is greater than the thickness of the connecting arm 521. The thinner connecting arm 521 is located above the connecting terminals 40a, without occupying the space between the connecting terminals 40a and without increasing the thickness of the connecting portion 52, while the connecting post 522 and the connecting terminals 40a share a portion of the space in the thickness direction of the display device 100.

[0152] Therefore, to solve the above problems, this application, based on the ability of the sheet metal part 60 fixed to the connecting part 52 to reduce the risk of stripping and reduce the thickness of the connecting part 52, adopts a design in which the connecting part 52 includes a connecting arm 521 and a connecting post 522. At least a portion of the projection of the connecting arm 521 onto the mounting surface 401 falls between the projections of the first terminal 40a1 and the second terminal 40a2 onto the mounting surface 401. Along the second direction X, the distance from the surface of the connecting arm 521 away from the rear housing 30 to the mounting surface 401 is greater than the thickness of the first terminal 40a1 and the second terminal 40a2. Furthermore, the connecting post 522 is located on the side of the first terminal 40a1 away from the clearance opening 50a along the first direction Y. That is, in this application, during the installation process of the connecting part 52... This allows the connecting arm 521 to be installed without obstructing the space between two adjacent terminals, and the connecting post 522 to extend into the space behind the connecting terminal 40a away from the clearance opening 50a. This ensures that the connecting post 522 does not occupy the space between the first terminal 40a1 and the second terminal 40a2, and the connecting arm 521 does not occupy the space between the two terminals in the second direction X. As a result, the entire connecting part 52 does not occupy the space between the two terminals. In this way, the interference between the connecting part 52 and the connecting terminal 40a can be reduced, and the distance between any two adjacent connecting terminals 40a can be shortened. This allows the connecting terminals 40a on the circuit board 40 to be arranged more compactly, thereby ensuring the overall compactness of the circuit board 40 layout.

[0153] It can be understood that the extension of the connecting post 522 along the second direction X toward the circuit board 40 may include: the connecting post 522 extending into a space in the thickness direction of the display device 100 that does not share the same thickness as the connecting terminal 40a, or extending into a space in the thickness direction of the display device 100 that shares the same thickness as the connecting terminal 40a. In other words, the distance from the surface of the connecting post 522 facing away from the rear housing 30 to the mounting surface 401 along the second direction X is greater than or equal to or less than the thickness of the first terminal 40a1 and the second terminal 40a2.

[0154] In other words, along the second direction X, the distance h2 from the surface of the connecting post 522 away from the rear housing 30 to the mounting surface 401 is greater than or equal to or less than the thickness T of the first terminal 40a1 and the second terminal 40a2.

[0155] It is understandable that in the first example, the distance from the surface of the connecting post 522 facing away from the rear housing 30 along the second direction X to the mounting surface 401 is greater than the thickness of the first terminal 40a1 and the second terminal 40a2. That is, the connecting post 522 does not share a thickness space with the connecting terminal 40a in the second direction X, and the connecting part 52 is located entirely above the connecting terminal 40a (refer to...). Figure 7 (The top and bottom directions of the paper).

[0156] In the second example, the distance from the surface of the connecting post 522 away from the rear housing 30 along the second direction X to the mounting surface 401 is equal to the thickness of the first terminal 40a1 and the second terminal 40a2. That is, the connecting post 522 does not share the thickness space with the connecting terminal 40a in the second direction X, and the surface of the connecting post 522 away from the rear housing 30 is approximately flush with the surfaces of the first terminal 40a1 and the second terminal 40a2 facing the rear housing 30.

[0157] Since the sheet metal part is fixed on the connecting column, and the connection between the sheet metal part and the first threaded fastener can reduce the thickness of the connecting column itself in the second direction, in the two examples above, the overall thickness of the connecting part can also be reduced, thereby reducing the overall thickness of the display device.

[0158] In the third example, the distance from the surface of the connecting post 522 facing away from the rear housing 30 along the second direction X to the mounting surface 401 is less than the thickness of the first terminal 40a1 and the second terminal 40a2. In this example, at least a portion of the projection of the connecting post 522 onto the plane perpendicular to the first direction Y falls on the projection of the first terminal 40a1 or the second terminal 40a2 onto the plane perpendicular to the first direction Y. In the thickness direction of the display device 100, the thickness of the connecting post 522 is greater than the thickness of the connecting arm 521. The thinner connecting arm 521 is located above the connecting terminals 40a, without occupying the space between the connecting terminals 40a and without increasing the thickness of the connecting portion 52, while the connecting post 522 and the connecting terminals 40a share a portion of the space in the thickness direction of the display device 100. This allows the connecting post 522 to not occupy additional space in the thickness direction of the display device 100, effectively preventing the connecting portion 52 of the terminal board 50 from being excessively raised in the second direction X. This results in a better overall thickness reduction effect for the display device 100, thus facilitating the thinning of the display device 100. Furthermore, in this example, even if the connecting post 522 temporarily interferes with the connecting terminal 40a in terms of thickness during the insertion and installation process, because the overall thickness of the connecting portion 52 is reduced, the space behind the connecting post 522, located away from the clearance opening 50a, can be offset from the connecting terminal 40a in the first direction Y after assembly without interference, thus facilitating the assembly of the terminal board 50.

[0159] Since the connecting portion 52 is a structure extending relative to the main body plate 51 along the first direction Y, sufficient strength is required. Preferably, the connecting arm 521 is approximately triangular in shape, with a larger width on the side of the connecting arm 521 closer to the main body plate 51. From the main body plate 51 towards the connecting post 522, the size of the connecting arm 521 gradually decreases in the third direction Z. The connecting post 522 connects to the side of the connecting arm 521 with the smaller size, so that the size of the connecting post 522 in the third direction Z is approximately the same as the minimum size of the connecting arm 521 in the third direction Z. This arrangement ensures strength while preventing the overall size of the connecting portion 52 in the third direction Z from becoming too large, further reducing the degree of interference between the connecting portion 52 and the connecting terminal 40a.

[0160] In some embodiments, the dimension of the connecting post 522 in the second direction X is 3mm to 6mm. Optionally, the dimension of the connecting post 522 in the second direction X can be 3mm to 5mm, 4mm to 6mm, or 3.5mm to 5.5mm, etc. For example, the dimension of the connecting post 522 in the second direction X can be 4mm, 4.5mm, or 5mm, etc.

[0161] If the connecting post 522 is too large in the second direction X, resulting in an excessively thick connecting post 522, the length of the connecting post 522 extending toward the circuit board 40 in the second direction X will be too long. This will cause excessive interference between the connecting post 522 and the connecting terminal 40a in the second direction X, making it difficult for the connecting post 522 to be pushed in from between two adjacent connecting terminals 40a in the second direction X. This will affect the assembly of the terminal board 50. Furthermore, while maintaining a sufficient distance between the connecting post 522 and the circuit board 40, the connecting portion 52 in the second direction X will be raised as a whole, which is not conducive to reducing the thickness of the display device 100. If the dimension of the connecting post 522 in the second direction X is too small, resulting in the connecting post 522 being too thin, it will not only affect the structural strength of the connecting post 522 and make it prone to deformation, thus failing to guarantee the stability of the sheet metal part 60, but may also cause the depth of the second through hole 50b to be too shallow. After the first threaded fastener 60b is installed, the bottom of the first threaded fastener 60b will be excessively exposed outside the second through hole 50b, increasing the risk of short circuit when the first threaded fastener 60b contacts the circuit board 40.

[0162] Therefore, by limiting the size of the connecting post 522 in the second direction X, this application can control the thickness of the connecting post 522 within a reasonable range. This avoids the connecting post 522 being too thick, which would reduce the interference between the connecting post 522 of the terminal board 50 and the circuit board 40 during installation and is more conducive to the thinning of the display device 100. At the same time, it also avoids the connecting post 522 being too thin, which better ensures that the connecting post 522 of the terminal board 50 has sufficient structural strength. Furthermore, without changing the length of the first threaded fastener 60b, it can also avoid the first threaded fastener 60b being excessively exposed outside the connecting post 522. This can better avoid or reduce the risk of short circuits caused by the first threaded fastener 60b being exposed outside and contacting components on the circuit board 40.

[0163] Combination Figure 9 and Figure 10 In some embodiments, the sheet metal part 60 is provided with a protrusion 60c protruding along the second direction X, the protrusion 60c being at least partially located in the second through hole 50b, and the protrusion 60c being provided with a first threaded hole 60a.

[0164] By providing a protrusion 60c protruding along the second direction X on the sheet metal part 60, and providing a first threaded hole 60a on the protrusion 60c, and making the protrusion 60c at least partially located in the second through hole 50b, that is, the first threaded hole 60a is formed by the structure of the connecting part 52 itself, and the first threaded hole 60a is provided in the space where the second through hole 50b is located. With this configuration, under the premise that the first threaded fastener 60b can be reliably connected to the rear shell 30 and the terminal plate 50 by connecting with the sheet metal part 60, the first threaded hole 60a and the second through hole 50b can also be reused in space, so as not to occupy additional space of the first threaded hole 60a in the second direction X. This makes the size of the terminal plate 50 in the second direction X smaller, and can avoid or reduce the risk of interference with the connecting terminal 40a caused by the excessive thickness of the terminal plate 50 in the second direction X. Furthermore, by using the design of the protrusion 60c in the second through hole 50b, the thickness of the display device 100 can be further reduced.

[0165] Furthermore, by providing at least a portion of the protrusion 60c in the second through hole 50b of the connecting portion 52, the inner wall surface of the connecting portion 52, which surrounds the second through hole 50b, can provide a certain limiting effect on the circumference of the protrusion 60c. That is, the second through hole of the connecting portion 52 can be used to form a certain pre-fixing and constraint effect on the sheet metal part 60, which is more conducive to the assembly of the sheet metal part 60 and improves the stability of the sheet metal part 60.

[0166] It is understood that the size and shape of the protrusion 60c are adapted to the second through hole 50b, and the protrusion 60c can be directly inserted into the second through hole 50b for pre-fixation during assembly.

[0167] Please refer to the following: Figure 6 , Figures 8 to 10 In some embodiments, the connecting portion 52 has a first surface 501 and a second surface 502 disposed opposite to each other along the second direction X, and the second through hole 50b extends from the first surface 501 to the second surface 502.

[0168] As can be seen from the foregoing, the end of the first threaded fastener 60b away from the rear housing 30 is located in the second through hole 50b, that is, the end of the first threaded fastener 60b away from the rear housing 30 does not protrude from the second surface 502.

[0169] When the terminal block 50 includes a body plate portion 51 and a connecting portion 52, the connecting portion 52 has a first surface 501 and a second surface 502 disposed opposite to each other.

[0170] Continue reading Figure 9 and Figure 10In some embodiments, the sheet metal part 60 includes a main body 61 disposed on the first surface 501, and the main body 61 is provided with a first threaded hole 60a.

[0171] As described above, the sheet metal part 60 is provided with a protrusion 60c protruding along the second direction X, and the protrusion 60c is provided with a first threaded hole 60a. In some embodiments, the protrusion 60c is located on the main body part 61, and the protrusion 60c protrudes in the direction from the first surface 501 to the second surface 502. By providing the protrusion 60c, the sheet metal part 60 only needs to protrude partially along the second direction X, thus avoiding the need for the entire sheet metal part 60 to protrude. On the one hand, this reduces the material used in the sheet metal part 60 and lowers the cost; on the other hand, it avoids the problem that the entire sheet metal part 60 protruding would occupy too much space, which is not conducive to the thin and light design of the display device 100.

[0172] In some embodiments, the sheet metal part 60 includes an extension 62. The extension 62 is connected to both sides of the main body part 61 in the radial direction of the first threaded hole 60a. The extension 62 extends in the second direction X, and one end of the extension 62 away from the main body part 61 is connected to the second surface 502 to fix the main body part 61 to the connecting part 52.

[0173] It is worth noting that the number of extensions 62 is at least two, for example, two, three or more. When there are two extensions 62, the two extensions 62 are located on the same straight line in the radial direction of the first threaded hole 60a, and the two extensions 62 are symmetrically arranged. For ease of understanding, the following description will take two symmetrically arranged extensions 62 as an example.

[0174] In this application, the sheet metal part 60 is designed to include a main body 61 and an extension 62. The main body 61, which is used to connect with the first threaded fastener 60b, is disposed on the first surface 501. The extension 62 extends along the second direction Y (the thickness direction of the display device 100) and is fixed to the second surface 502 by means of the extension 62 to fix the sheet metal part 60 to the connecting part 52. With this arrangement, the sheet metal part 60 can be arranged to roughly cover the terminal plate 50 in the second direction X, so that the terminal plate 50 can provide support for the sheet metal part 60 on both surfaces along the second direction X, thereby making the connection of the sheet metal part 60 more stable and reliable.

[0175] It is understood that the extension 62 extends along the second direction X, and the end of the extension 62 away from the main body 61 is connected to the second surface. The extension 62 is equivalent to the fixing part of the sheet metal part 60. That is, the main body 61 is fixed to the connecting part 52 by connecting the extension 62 with the connecting part 52. Compared with the extension 62 extending along the first direction Y or along other directions, the extension 62 extending along the second direction X can make the overall structure of the sheet metal part 60 more compact. It can avoid the situation where the connecting part 52 needs to increase its size in other directions in order to connect the extension 62 with the connecting part 52. It can avoid the problem that the connecting part 52 will interfere with the connecting terminal due to its excessive size.

[0176] Optionally, the first surface 501 can be configured to be closer to the rear housing 30, and the second surface 502 can be configured to be farther away from the first surface 501. Of course, in other embodiments, the first surface 501 can also be configured to be farther away from the rear housing 30.

[0177] Preferably, the first surface 501 can be configured to be closer to the rear housing 30. In this case, the main body 61 is positioned even closer to the rear housing 30. Since the first threaded hole 60a is located on the protrusion 60c, the first threaded fastener 60b begins to screw into the first threaded hole 60a after passing through the first through hole 30c. As the first threaded fastener 60b is screwed in deeper, the entire thread structure on the first threaded fastener 60b passes through the thread structure of the first threaded hole 60a. Finally, the first threaded hole 60a connects to the end of the first threaded fastener 60b closest to the rear housing 30. This means that if the first threaded fastener 60b comes out, it requires a considerable screwing depth, increasing the difficulty of disengagement. Therefore, configuring the first surface 501 closer to the rear housing 30 and positioning the main body 61 on this first surface 501 makes the connection of the second threaded fastener 30b more secure.

[0178] Continue reading Figure 6 , Figures 7 to 9 In some embodiments, the first surface 501 is provided with a through hole 501a that extends to the second surface 502, and the extension 62 is provided through the through hole 501a. One end of the extension 62 away from the main body 61 extends out of the through hole 501a and is bent to form a hook 62a.

[0179] In some embodiments, the main body 61 and the extension 62 may be integrally formed, the extension 62 is formed by bending along the axial direction of the first threaded hole 60a, and the end of the extension 62 away from the main body 61 is formed by bending along the radial direction of the first threaded hole 60a.

[0180] It is understood that the number of perforations 501a can also be two. The two perforations 501a are located on the same straight line along the radial direction of the second through hole 50b and are symmetrically arranged. Each perforation 501a is provided for each extension 62, and the hooks 62a of the two extensions 62 are arranged opposite each other along the radial direction of the first threaded hole 60a.

[0181] By providing a through hole 501a extending to the second surface 502 on the first surface 501 of the terminal plate 50 for the extension 62 to pass through, and by bending the end of the extension 62 to form a hook 62a, the hook 62a and the second surface 502 can cooperate to form a limit in the axial direction (second direction X) of the second through hole 50b, restricting the sheet metal part 60 from coming out of the through hole 501a in this direction. This achieves a stable connection between the sheet metal part 60 and the connecting part 52 of the terminal plate 50. Since the sheet metal part 60 is fixed to the connecting part 52 by bending to form a hook, that is, the sheet metal part 60 uses its own structural deformation to achieve a fixed connection with the connecting part 52 of the terminal plate 50. In this way, there is no need to set additional positioning or locking structures on the terminal plate 50 and the sheet metal part 60, which simplifies the structure of the terminal plate 50 and the sheet metal part 60, helps to save mold costs, and is more conducive to the molding of the terminal plate 50 and the sheet metal part 60.

[0182] Furthermore, by using a perforation to allow the extension 62 to pass through, and the perforation being made inside the sheet metal part 60, the extension 62 of the sheet metal part 60 can be embedded inside the terminal plate 50, so that the outer periphery of the extension 62 can be effectively constrained, thereby making the connection of the sheet metal part 60 more secure and thus enhancing the reliability of the connection of the sheet metal part 60.

[0183] In addition, by embedding the sheet metal part 60 into the terminal plate 50, the structure of the terminal plate 50 can be strengthened, making the terminal plate 50 less prone to deformation.

[0184] Optionally, the main body 61 can be a sheet or plate structure, which makes the sheet metal part 60 smaller and does not occupy extra space. In addition, the extension 62 can also be a sheet or plate structure, which makes it easy for the end of the extension 62 to be bent and deformed.

[0185] Combination Figure 9 and Figure 10 In some embodiments, the end of the extension 62 away from the main body 61 is bent toward the second through hole 50b to form a hook 62a, and the hook 62a is inclined toward the main body 61.

[0186] It is understandable that the angle between the hook 62a and the extension 62 is less than 90 degrees, so that the extension 62 roughly presents a barbed structure.

[0187] By bending the end of the extension 62 away from the main body 61 towards the second through hole 50b, and making the hook 62a inclined towards the main body 61, that is, the hook 62a and the extension 62 have a barbed structure, the hook 62a is less likely to deform when subjected to external force, making it more difficult for the sheet metal part 60 to detach from the through hole 501a, thereby improving the connection strength of the sheet metal part 60. Furthermore, the bending of the end of the extension 62 away from the main body 61 towards the second through hole 50b, that is, the hook 62a is bent towards the axis of the first threaded hole 60a, presenting an inward contraction rather than an outward opening, makes the overall volume of the sheet metal part 60 smaller. It will not occupy extra space on the connection part 52 assembled to the terminal plate 50, so that even if the sheet metal part 60 is fixed, the connection part 52 can still have a structure that is roughly without the sheet metal part 60, so that the overall size of the connection part 52 remains unchanged.

[0188] Combination Figure 11 In some embodiments, the second surface 502 is provided with a first groove 502a, and the second through hole 50b and the through hole 501a are both connected to the first groove 502a. The hook 62a is located in the first groove 502a and can abut against the bottom wall of the first groove 502a.

[0189] By providing a first groove 502a on the second surface 502, both the second through hole 50b and the through hole 501a are located in the first groove 502a. A hook 62a is placed in the first groove 502a and abuts against the bottom wall of the groove. That is, after the end of the extension 62 away from the main body 61 passes through the through hole, it can be bent into the first groove. While ensuring a stable connection between the sheet metal part 60 and the terminal board 50, this avoids the hook protruding from the second surface and occupying unnecessary space, thus preventing the thickness of the connecting part 52 from increasing due to the hook extending outside. Furthermore, when the second surface is close to the circuit board, since the sheet metal part 60 is metal, this arrangement prevents the metal hook from protruding from the second surface, thus avoiding the risk of short circuits caused by contact between the hook and components on the circuit board.

[0190] In some embodiments, the surface of the connecting portion 52 is provided with a second groove 501b, and at least a portion of the sheet metal part 60 is accommodated in the second groove 501b.

[0191] By providing a second groove 501b on the surface of the connecting portion 52 of the terminal plate 50, at least a portion of the sheet metal part 60 is accommodated in the second groove 501b. This allows the sheet metal part 60 to utilize the space on the terminal plate 50 without occupying extra space along the second direction X, or reduces the space occupied along the second direction X. In other words, the method of fixing the sheet metal part 60 to the connecting portion 52 in this application can utilize a portion of the structural space on the connecting portion 52 without excessively increasing the space occupied in the thickness direction of the display device 100. This ensures that even if the sheet metal part 60 is fixed to the connecting portion 52, the volume of the connecting portion 52 will not increase excessively, thereby better controlling the reduction of the thickness of the connecting portion 52 in the second direction X. Furthermore, it is more conducive to the compact design of the internal structure of the display device 100, and further facilitates the reduction of the overall thickness of the display device 100.

[0192] Combination Figure 6 and Figure 9 In some embodiments, the first surface 501 is provided with the second groove 501b, the main body 61 is accommodated in the second groove 501b, and the through hole 501a is located in the second groove 501b.

[0193] With the hook 62a positioned within the first groove 502a, it is evident that the entire sheet metal part 60 utilizes the space on the terminal plate 50 in the second direction X, without occupying any space outside the terminal plate 50. This design effectively secures the sheet metal part 60 while minimizing the space occupied within the display device 100. This not only reduces the size of the terminal plate 50 in the second direction X, but also addresses the limited space available for connecting terminals 40a or electronic components within the area occupied by the sheet metal part 60. This design further optimizes space utilization and reduces the risk of interference between the sheet metal part 60 and the connecting terminals 40a or electronic components.

[0194] Combination Figure 12 and Figure 13 In some embodiments, the connecting portion 52 further has an outer peripheral surface 503, which is connected between the first surface 501 and the second surface 502.

[0195] In some embodiments, the extension 62 covers at least a portion of the outer peripheral surface 503, and the end of the extension 62 away from the main body 61 can be bent to form a hook 62a, which abuts against the second surface 502.

[0196] In some embodiments, the end of the extension 62 away from the main body 61 is bent along the third direction Z, so that the hook 62a is substantially perpendicular to the extension 62, and the extension 62 is substantially L-shaped and abuts against the second surface 502.

[0197] As can be seen from the foregoing, the terminal plate 50 includes a body plate portion 51 and a connecting portion 52. In some embodiments, the connecting portion 52 has an outer peripheral surface 503, and two extension portions 62 cover at least a portion of the outer peripheral surface 503.

[0198] By covering at least a portion of the outer peripheral surface 503 of the terminal plate 50 with the extension 62 and forming a structure that abuts against the second surface 502 through bending, the assembly method of this outer covering is simpler and improves assembly efficiency, provided that the hook 62a can abut against the connecting part 52 to prevent the sheet metal part 60 from falling off. Furthermore, by covering at least a portion of the outer peripheral surface 503 of the terminal plate 50 with the extension 62, the structural strength of the connecting part of the terminal plate 50 can be strengthened, the structural mechanical properties of the terminal plate 50 can be improved, and the terminal plate 50 is less prone to deformation.

[0199] In some embodiments, a third groove 503a is provided on the outer peripheral surface 503, and the extension 62 may be located in the third groove 503a.

[0200] In some embodiments, the third groove 503a is connected to the second groove 501b on the first surface 501, so that most of the sheet metal part 60 is accommodated by the space on the terminal plate 50, without occupying additional space outside the terminal plate 50.

[0201] In some embodiments, the depth of the first threaded hole 60a is 1 mm to 1.4 mm. For example, the depth of the first threaded hole 60a can be 1 mm, 1.2 mm, or 1.4 mm, etc.

[0202] This application uses a first threaded fastener 60b to fix the rear shell 30 to the sheet metal part 60, thereby connecting the rear shell 30 to the terminal plate 50. Since the sheet metal part 60 is a metal part, the first threaded fastener 60b is not directly screwed to the plastic connection part 52. Because the sheet metal part 60 is made of metal, it has a high coefficient of friction and high hardness, and is not easy to deform. This makes it less likely for the first threaded fastener 60b to slip when connected to the sheet metal part 60. Therefore, a shorter screw length can ensure a reliable connection of the first threaded fastener 60b.

[0203] If the depth of the first threaded hole 60a is less than 1mm, it is too shallow, and the length of the sheet metal part 60 involved in the screwing is too short. Even if the first threaded fastener is connected to the metal sheet metal part, the first threaded fastener may easily come out of the first threaded hole 60a, which is not conducive to the stability of the connection. If the depth of the first threaded hole 60a is greater than 1.4mm, it is too deep, and the length of the sheet metal part 60 involved in the screwing is too long. During the assembly of the first threaded fastener 60b, the rotation time in the second threaded hole is too long, which is not conducive to improving assembly efficiency. Furthermore, if the depth of the first threaded hole 60a is too long, it will cause the thickness of the part of the sheet metal part 60 where the first threaded hole 60a is located to be too thick. When the sheet metal part 60 is fixed to the connecting part 52, it will cause the overall thickness of the connecting part 52 to increase.

[0204] Therefore, by setting the depth of the first threaded hole 60a within a reasonable range, the depth of the first threaded hole 60a is not too shallow, which would affect the reliability of the screw connection, thus enabling a reliable connection between the rear shell 30 and the terminal plate 50. At the same time, the depth of the first threaded hole 60a is not too deep, which would prevent the first threaded fastener 60b from rotating in the first threaded hole 60a for too long during assembly, thereby improving assembly efficiency and preventing the thickening of the sheet metal part 60 from causing an increase in the thickness of the connecting part 52.
