Description

Technical Field

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

[0002] Display devices (such as televisions) are mostly placed on a tabletop using a stand or mounted on a wall using a wall mount. Taking tabletop placement as an example, related technologies typically involve pre-drilling threaded holes in both the television and the stand, then using screws to connect the stand to the television, allowing it to stand upright on the table. However, this installation method often suffers from problems such as low installation efficiency and difficulty in disassembly and reassembly. Utility Model Content

[0003] This application discloses a display device that enables a detachable connection of the base to the display device, while the method of assembling and disassembling the base is simple and efficient.

[0004] To achieve the above objectives, embodiments of this application disclose a display device, including:

[0005] A display device, the display device comprising:

[0006] Display panel;

[0007] A backlight module, wherein the backlight module is used to support the display panel;

[0008] The back cover is connected to the backlight module, and the bottom surface of the back cover has mounting holes extending along the height direction of the display panel.

[0009] The base includes:

[0010] The support legs are used to support the display device;

[0011] Mounting post, which is connected to the top of the support leg and extends along the height direction of the display panel, is configured to pass through the mounting hole so that the base and the display device can be detachably connected;

[0012] The inner wall surface of the mounting hole is provided with:

[0013] A clearance groove extends from the opening of the mounting hole along the height direction of the display panel;

[0014] A limiting groove extends along the circumferential direction of the mounting hole and communicates with the clearance groove;

[0015] The outer circumferential surface of the mounting column is provided with:

[0016] A protrusion is configured to enter the limiting groove along the clearance groove, the limiting groove being configured to restrict the displacement of the protrusion along the circumferential and axial directions of the mounting hole.

[0017] The display device disclosed in this application features a relief groove and a limiting groove communicating with the relief groove within the mounting hole of the rear housing. A protrusion is provided on the mounting post of the base, allowing the protrusion to enter the limiting groove along the relief groove. The limiting groove restricts the displacement of the protrusion along the circumferential and axial directions of the mounting hole, making the connection between the base and the display device more stable and reliable, effectively preventing the base from loosening or falling off during use. This connection method also offers the advantages of easy and efficient assembly and disassembly; users can install and remove the base simply by rotating it, greatly improving ease of use. Furthermore, this design conceals the mounting post of the base within the mounting hole, achieving a hidden mounting structure and resulting in a cleaner and more aesthetically pleasing appearance, effectively avoiding the problem of exposed mounting structures affecting the overall visual effect of the display device.

[0018] In some embodiments of this application, the limiting groove includes:

[0019] The first sub-slot is connected to the clearance slot;

[0020] The second sub-slot is connected to the first sub-slot, and the dimension of the first sub-slot in the height direction of the display panel is smaller than the dimension of the second sub-slot in the height direction of the display panel.

[0021] The protrusion includes:

[0022] The first sub-convex part;

[0023] The second sub-protrusion is connected to the first sub-protrusion, and the width of the first sub-protrusion in the height direction of the display panel is smaller than the width of the second sub-protrusion in the height direction of the display panel.

[0024] When the mounting post rotates to allow the protrusion to enter the limiting groove, the second sub-protrusion abuts against the second sub-groove, and the first sub-protrusion abuts against the first sub-groove. The first sub-groove is configured to restrict the displacement of the second sub-protrusion along the circumferential direction of the mounting hole, and the first sub-groove and the second sub-groove are respectively configured to restrict the displacement of the first sub-protrusion and the second sub-protrusion along the axial direction of the mounting hole.

[0025] By configuring the limiting groove to include a first sub-groove and a second sub-groove that are connected, with the first sub-groove's dimension in the height direction of the display panel being smaller than that of the second sub-groove, and configuring the protrusion to include a first sub-protrusion and a second sub-protrusion that are connected, when the mounting post extends into the mounting hole along the clearance groove and rotates, the second sub-protrusion abuts against the first sub-groove, and the first sub-protrusion abuts against the first sub-groove. This allows the first sub-groove to restrict the position of the second sub-protrusion along the circumferential direction of the mounting hole. Simultaneously, the first and second sub-grooves can also respectively restrict the displacement of the first and second sub-protrusions along the axial direction of the mounting hole. This structural design further enhances the stability and reliability of the connection between the base and the display device. In practical applications, the user simply aligns the mounting post of the base with the mounting hole on the rear shell, slides the protrusion along the clearance groove, and then rotates the base to allow the protrusion to smoothly enter the limiting groove, thus completing the base installation. For disassembly, the base is rotated in the opposite direction to allow the protrusion to exit the limiting groove and slide out along the clearance groove, making the base easy to remove. This design is not only easy to operate, but also effectively improves the user experience.

[0026] In some embodiments of this application, a first guide surface is connected between the first sub-groove and the second sub-groove, and a second guide surface that mates with the first guide surface is connected between the first sub-protrusion and the second sub-protrusion.

[0027] The second sub-protrusion is configured to abut against the second sub-groove under the guidance of the first guide surface and the second guide surface, so as to limit the displacement of the second sub-protrusion along the circumferential direction of the mounting hole.

[0028] By connecting a first guide surface between the first and second sub-slots, and correspondingly connecting a second guide surface between the first and second sub-protrusions, with the second guide surface engaging with the first guide surface, the second sub-protrusion can be guided by the engagement of the first and second guide surfaces to abut against the second sub-slot, thereby limiting the displacement of the second sub-protrusion along the circumferential direction of the mounting hole, and thus achieving the connection of the mounting post in the mounting hole. This design of the first and second guide surfaces makes the installation process smoother, reduces friction and resistance during installation, and improves installation efficiency. At the same time, the engagement of the first and second guide surfaces also enhances the stability of the connection, making the connection between the base and the display device more secure and reliable.

[0029] In some embodiments of this application, the mounting column includes a first column segment and a second column segment, one end of the second column segment is connected to the support leg, the other end of the second column segment is connected to the first column segment, and the outer diameter of the first column segment is smaller than the outer diameter of the second column segment;

[0030] Both the first column segment and the second column segment are provided with the protrusion, and along the height direction of the display panel, the protrusion on the first column segment and the protrusion on the second column segment are correspondingly arranged;

[0031] The mounting hole includes a first hole segment and a second hole segment. The second hole segment is connected to the opening of the mounting hole. The first hole segment and the second hole segment are connected. The diameter of the first hole segment is smaller than the diameter of the second hole segment.

[0032] Both the first hole segment and the second hole segment are provided with the clearance groove and the limiting groove. Along the height direction of the display panel, the clearance groove on the first hole segment is correspondingly provided with the clearance groove on the second hole segment, and the limiting groove on the first hole segment is correspondingly provided with the limiting groove on the second hole segment.

[0033] The protrusion of the first column segment is configured to enter the limiting groove of the first hole segment along the clearance groove of the first hole segment, and the protrusion of the second column segment is configured to enter the limiting groove of the second hole segment along the clearance groove of the second hole segment.

[0034] It is understandable that the mating connection between the first and second column segments and the first and second hole segments makes the connection between the mounting post and the mounting hole more compact and stable. Due to its smaller outer diameter, the first column segment can smoothly enter the smaller space formed by the first hole segment, and its protrusion engages with the limiting groove of the first hole segment to achieve axial and circumferential positioning along the mounting hole. Similarly, the second column segment, through its protrusion engaging with the limiting groove of the second hole segment, further enhances the stability of the mounting post in the mounting hole. This segmented design not only improves the reliability of the connection but also makes the installation process more flexible and convenient. In actual operation, the installer can first align and insert the first column segment into the first hole segment, then align and insert the second column segment into the second hole segment, and finally rotate it to allow the protrusion to smoothly enter the limiting groove, completing the entire installation process. This design effectively avoids installation difficulties or unstable connections caused by improper mating of a single column segment with the inner wall surface, thus contributing to improving the overall structural strength and stability of the display device.

[0035] In some embodiments of this application, the length of the first column segment is greater than the length of the second column segment along the height direction of the display panel;

[0036] The first column segment includes a first end and a second end that are opposite each other along the height direction of the display panel;

[0037] The second column segment includes a third end and a fourth end opposite to each other along the height direction of the display panel, the third end being connected to the second end, and the fourth end being connected to the support leg.

[0038] The first end and the third end are both provided with the protrusion.

[0039] By setting the length of the first column segment along the height of the display panel to be greater than that of the second column segment along the height of the display panel, the overall structural strength of the mounting column can be ensured while allowing the first column segment to better penetrate into the mounting hole and achieve a tighter fit with the first hole segment. This design of length difference makes the force distribution of the mounting column in the mounting hole more reasonable. The first column segment undertakes the main connection and positioning functions, while the second column segment plays an auxiliary support and stabilizing role.

[0040] Specifically, when the display device is subjected to external forces, the longer first column effectively disperses and transmits the force, reducing the risk of loosening or damage to connections due to excessive localized stress. Simultaneously, the presence of the second column enhances the overall rigidity of the mounting post, preventing bending or deformation during stress and ensuring a consistently stable and reliable connection between the base and the display device. Furthermore, this length configuration helps optimize the internal space layout of the display device. The longer first column allows for more flexible adjustment of its position within the mounting holes to accommodate internal functional components or wiring requirements of different sizes and shapes. The relatively shorter second column, on the other hand, avoids excessive encroachment or interference with internal space, allowing the display device to maintain structural stability while providing ample internal space for other critical components, thus improving overall performance and functional versatility.

[0041] It is understandable that by setting protrusions in both the first and second column sections, it is possible to ensure that the mounting column is positioned and connected to the inner wall of the mounting hole from two different height positions during insertion. This design further enhances the stability of the connection between the mounting column and the mounting hole, effectively preventing overall loosening due to the failure of a single connection point.

[0042] Furthermore, since the length of the first column segment is greater than that of the second column segment, a protrusion is provided at the first end of the first column segment and at the third end of the second column segment, creating a certain distance between the protrusions. During installation, this spacing design prevents interference caused by both protrusions simultaneously entering the same limiting groove, ensuring smooth and accurate installation. Simultaneously, when the display device is subjected to external forces from different directions, the two protrusions at different heights can respectively bear and disperse the force, making the connection between the mounting post and the mounting hole more stable and reliable, reducing the risk of loosening or damage due to uneven stress.

[0043] Compared to placing the protrusions at the second end of the first column segment and the fourth end of the second column segment, the arrangement of this application is beneficial to enhancing the anti-torsion ability of the mounting column in the mounting hole. When the display device is subjected to lateral force or torque, the two protrusions can form a tighter fit with the limiting groove, effectively preventing the mounting column from rotating relative to the mounting hole, thereby ensuring that the connection between the base and the display device remains stable.

[0044] In some embodiments of this application, both the first column segment and the second column segment are cylindrical segments, and the first column segment and the second column segment share a common center.

[0045] The protrusion on the first column segment extends along the circumferential direction of the first column segment, and the outer peripheral surface of the protrusion on the first column segment is an arc surface. In the height direction of the display panel, the projection of the arc surface is located on the outer peripheral surface of the second column segment.

[0046] The first and second column segments are designed as cylindrical segments with the same center. The protrusion on the first column segment extends circumferentially and has an arc surface on its outer circumference. At the same time, the projection of the arc surface in the height direction of the display panel is located on the outer circumference of the second column segment. That is, the radius of the circle corresponding to the arc surface of the protrusion on the first column segment is approximately the same as the radius of the second column segment. This makes it easier for the mounting column to be inserted into the mounting hole, reducing installation difficulties or jamming caused by axial deviation. Installers can more easily align the mounting column with the mounting hole, which helps to improve the installation efficiency of the display device.

[0047] Secondly, the outer circumference of the protrusion is curved, and its projection lies on the outer circumference of the second column segment. This design allows for a closer fit between the protrusion and the limiting groove. Once the protrusion enters the limiting groove, the curved surface better adapts to the inner wall of the groove, increasing the contact area and thus improving the stability of the connection between the base and the display device. Furthermore, when the display device is subjected to external forces, this close-fitting connection effectively disperses the force, reducing the risk of loosening or damage due to excessive localized stress.

[0048] Furthermore, the concentric cylindrical segment structure ensures more even stress distribution on the mounting posts within the mounting holes. When the display device is subjected to external forces from different directions, the first and second pillars can share the load, preventing structural damage caused by excessive stress concentration on any one pillar.

[0049] In some embodiments of this application, the support leg extends along the thickness direction of the display panel;

[0050] The protrusion includes two parts, which are respectively located on both sides of the outer peripheral surface of the mounting post along the width direction of the display panel.

[0051] When the protrusion enters the limiting groove along the clearance groove, that is, when the base is installed in the display device, the support legs extend along the thickness direction of the display panel to support the display device. The two protrusions are respectively located on both sides of the outer peripheral surface of the mounting post along the width direction of the display panel. That is, the arrangement direction of the two protrusions on the outer peripheral surface of the mounting post is perpendicular to the extension direction of the support legs. This layout helps to further distribute the pressure of the display device on the base, making the base more evenly stressed, thereby improving the support stability and service life of the base.

[0052] Furthermore, since the two protrusions are arranged perpendicular to the extension direction of the support legs on the outer circumference of the mounting post, on the one hand, when the display device is subjected to forces from different directions, the two protrusions can limit the mounting post from different directions, enhancing the stability of the connection between the base and the display device, and effectively preventing the display device from shaking or shifting when subjected to external impacts; on the other hand, they can also provide intuitive guidance for installers, ensuring that the extension direction of the support legs naturally corresponds to the thickness direction of the display panel, ensuring the accuracy of the base installation orientation, and avoiding structural stress concentration or decreased support stability caused by incorrect installation orientation.

[0053] In some embodiments of this application, the two protrusions located on opposite sides of the outer peripheral surface of the same mounting post have different dimensions in the height direction of the display panel.

[0054] By setting two protrusions on the same mounting post with different dimensions in the height direction of the display panel, installers can distinguish the installation direction of the base by the different protrusions corresponding to different limiting grooves during installation, thereby avoiding installation errors caused by confusion.

[0055] In some embodiments of this application, the support leg includes a front support leg and a rear support leg, both of which extend along the thickness direction of the display panel, and the mounting post is connected between the front support leg and the rear support leg;

[0056] Along the thickness direction of the display panel, the length of the front support leg is greater than the length of the rear support leg.

[0057] By setting the length of the front support leg along the thickness of the display panel to be greater than that of the rear support leg, the display device not only provides cushioning and stability when subjected to external impact, but also further enhances the resistance when tilting forward, reducing the possibility of it tipping forward due to accidental collisions. Specifically, because the display panel is relatively fragile, a longer front support leg provides a larger support area and stronger anti-tipping moment when subjected to impact from the rear, effectively preventing the display device from tipping forward. Furthermore, since the rear of the display device is typically placed against a wall, the wall can act as a buffer when the device tilts backward, while a forward tilt could result in a direct fall to the ground and damage. Therefore, setting the length of the front support leg along the thickness of the display panel to be greater than that of the rear support leg is crucial for preventing the display device from tilting forward.

[0058] In some embodiments of this application, the base includes two bases, the mounting hole includes two mounting holes, the base is detachably connected to the mounting hole, and the two bases are spaced apart along the width direction of the display panel.

[0059] The two bases are spaced apart along the width of the display panel. This layout allows for a more balanced weight distribution, preventing center-of-gravity shifts caused by single-point support and effectively improving the stability of the display device when placed. Simultaneously, the spaced-apart bases enhance the overall anti-tipping capability of the display device. When subjected to external forces, the two bases share and disperse the force, reducing the risk of damage caused by excessive localized stress. Furthermore, this design provides greater flexibility for the internal structural layout of the display, facilitating the placement of other functional components or wiring space between the two bases, thus optimizing the utilization of the display device's internal space.

[0060] Compared with the prior art, the beneficial effects of this application are:

[0061] The display device disclosed in this application features a relief groove and a limiting groove communicating with the relief groove within the mounting hole of the rear housing. A protrusion is provided on the mounting post of the base, allowing the protrusion to enter the limiting groove along the relief groove. The limiting groove restricts the displacement of the protrusion along the circumferential and axial directions of the mounting hole, making the connection between the base and the display device more stable and reliable, effectively preventing the base from loosening or falling off during use. This connection method also offers the advantages of easy and efficient assembly and disassembly; users can install and remove the base simply by rotating it, significantly improving ease of use. Furthermore, this design conceals the mounting post of the base within the mounting hole, achieving a hidden mounting structure and resulting in a cleaner and more aesthetically pleasing appearance. This effectively avoids the problem of exposed mounting structures affecting the overall visual effect of the display device. Attached Figure Description

[0085] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0086] In this application, the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0087] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0088] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0089] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0090] In the description of this application, it should be noted that the singular forms of "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that terms such as "comprising / including" or "having" specify the presence of the stated features, integrals, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integrals, steps, operations, components, parts, or combinations thereof.

[0091] As a core electronic product, the placement and installation of display devices (taking televisions as a common example) has always been a key concern for consumers. Currently, most display devices on the market achieve stable placement in two main ways: one is to place the display device on a table or desktop, supported by a base structure; the other is to install the display device on the wall using a wall mount bracket, in order to save space and adapt to different home layouts.

[0092] Taking the common installation method of placing a TV on a table or desk as an example, in related technologies, to achieve a stable connection between the TV and the base structure, threaded holes are usually pre-drilled precisely at corresponding positions on the bottom casing of the TV and the base structure. During installation, installers need to use screws of specific sizes to screw each screw into the corresponding threaded holes on the TV and the base structure. The tight engagement of the threads achieves a secure threaded connection between the TV and the base structure.

[0093] However, the installation process is often cumbersome and time-consuming because it requires precise alignment of the threaded holes and tightening of each screw individually. Furthermore, this installation method presents significant inconvenience during disassembly and assembly. When users need to move, repair, or replace the TV stand, all screws must be unscrewed one by one. Additionally, due to prolonged use, the screws may corrode or become stuck in the threaded holes, making unscrewing them extremely difficult, sometimes requiring specialized tools. Screws are also prone to being lost or damaged during disassembly and assembly, further increasing the difficulty and cost. Moreover, frequent disassembly and assembly can cause wear and tear on the threaded holes in the TV and stand structure, affecting the stability of subsequent installations.

[0094] In view of this, the display device disclosed in this application can use a limiting groove to restrict the displacement of the protrusion along the circumferential and axial directions of the mounting hole. This makes the connection between the base and the display device more stable and reliable, effectively preventing the base from loosening or falling off during use. At the same time, this connection method is also simple and efficient to assemble and disassemble, and has a simple and beautiful appearance.

[0095] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0096] Please see Figure 1 , Figure 1This is one of the structural schematic diagrams of a display device provided in an embodiment of this application. This application discloses a display device 1000, which can be an organic light-emitting diode (OLED) display device, a light-emitting diode (LED) display device, a liquid crystal display (LCD) device, etc. This embodiment does not further limit the type of display device 1000.

[0097] The display device 1000 may include, but is not limited to, televisions, monitors, tablets, laptops, mobile phones, etc., and can be widely used in homes, offices, conference halls, exhibition halls, train stations, hospitals, or shopping malls. In this embodiment, the display device 1000 will be used as a television as an example, but it is not limited to this example.

[0098] It is understandable that the display device 1000 can be a borderless display device or a bordered display device. When the display device 1000 is a borderless display device, a decorative frame can be set around the outer perimeter of the display device 1000 to improve the aesthetics of the display device 1000.

[0099] Please see Figure 2 , Figure 2 This is a second schematic diagram of the structure of the display device provided in the embodiments of this application. In some embodiments, the display device 1000 includes a display device 100 and a base 200. The display device 100 is used to display image information, and the base 200 is used to support the display device 100. The base 200 is detachably connected to the display device 100 and is used to support the display device 100 on a table or bottom surface, etc.

[0100] Please see Figure 3 , Figure 3 An exploded view of a display device provided in an embodiment of this application. In some embodiments, the display device 100 includes a display panel 110 for displaying image information.

[0101] It is understood that the display panel 110 has an upper and lower side along the height direction, a left and right side along the width direction Y, and a front and rear side along the thickness direction X. The side of the display panel 110 facing the user is the front side, and the side of the display panel 110 away from the user is the rear side. When the display panel 110 is in a standing (e.g., placed on a table via a base 200) or hanging (e.g., hung on a wall via a wall mount bracket) state, the absolute height of the upper side of the display panel 110 is greater than the absolute height of the lower side.

[0102] It can be understood that the extension direction between the top and bottom sides is the height direction of the display panel 110, the extension direction between the left and right sides is the width direction Y of the display panel 110, and the extension direction between the front and rear sides is the thickness direction X of the display panel 110. It is known that among the width direction Y, the thickness direction X, and the height direction, each pair is perpendicular. That is to say, the width direction Y is perpendicular to the thickness direction X, the width direction Y is perpendicular to the height direction, and the thickness direction X is perpendicular to the height direction.

[0103] Optionally, the display panel 110 has a backlight side and a light-emitting side, which can be understood as the backlight side and the light-emitting side being two opposite sides of the display panel 110 along its thickness direction X.

[0104] In some embodiments, the display device 1000 includes a mid-frame (not shown), which may be fixedly connected to the four edges of the back panel 121 or detachably connected to the four edges of the back panel 121. This application embodiment does not limit this.

[0105] In some embodiments, the display device 100 includes a backlight module 120 (see...). Figure 1 The backlight module 120 is used to provide a light source for the display panel 110.

[0106] In some embodiments, the backlight module 120 includes a back plate 121, which supports a display panel 110, which is located on the front side of the back plate 121. The back plate 121 also has a light source (not shown) and an optical film assembly (not shown), arranged sequentially from the rear to the front of the display device 1000. Light emitted from the light source is projected onto the display panel 110 after passing through the optical film assembly, and image information is displayed on the display panel 110 after being processed by the display panel 110.

[0107] In some embodiments, the display device 100 includes a rear housing 130 connected to a back plate 121. Along the height direction of the display panel 110, the bottom surface of the rear housing 130 has a mounting hole 131 extending along the height direction of the display panel 110.

[0108] Please refer to the following: Figures 4 to 7 , Figure 4 This is a bottom view of the display device provided in the embodiments of this application. Figure 5 This is a schematic diagram of the structure of the back shell and the base provided in the embodiments of this application. Figure 6 This is a schematic diagram of the structure of the rear shell provided in an embodiment of this application. Figure 7This is one of the structural schematic diagrams of the base provided in the embodiments of this application. In some embodiments, the base 200 includes two bases and two mounting holes 131. The bases 200 are detachably connected to the mounting holes 131, and the two bases 200 are spaced apart along the width direction Y of the display panel 110. This arrangement of the two bases 200 spaced apart along the width direction Y of the display panel 110 allows for a more balanced weight distribution of the display device 100, thereby avoiding the problem of center of gravity shift caused by single-point support and effectively improving the stability of the display device 1000 when placed. Simultaneously, the spaced arrangement of the two bases 200 also enhances the overall anti-tipping capability of the display device 1000. When the display device 100 is subjected to external force, the two bases 200 can jointly bear and disperse the external force, reducing the risk of damage caused by excessive local force. Furthermore, this design provides more flexibility for the internal structural layout of the display device, facilitating the placement of other functional components or wiring space between the two bases 200, thus optimizing the internal space utilization efficiency of the display device 100.

[0109] Please refer to the following: Figures 7 to 9 , Figure 8 This is the second schematic diagram of the structure of the base provided in the embodiments of this application. Figure 9 for Figure 8 A partial enlarged view at point A. In some embodiments, the base 200 includes a support leg 210 and a mounting post 220. The support leg 210 supports the display device 100. The mounting post 220 is connected to the top end of the support leg 210 and extends along the height direction of the display panel 110. The mounting post 220 is configured to pass through a mounting hole 131 so that the base 200 is detachably connected to the display device 100.

[0110] In some embodiments, the mounting hole 131 may be a round hole, a square hole, or other polygonal hole, and correspondingly, the mounting post 220 may be a round post, a square post, or other polygonal post. This application does not limit this aspect.

[0111] Please refer to the following: Figures 10 to 11 , Figure 10 This is a bottom view of the rear shell provided in an embodiment of this application. Figure 11 for Figure 10A cross-sectional view of BB. In some embodiments, the inner wall surface 131a of the mounting hole 131 is provided with a relief groove 1311 and a limiting groove 1312. The relief groove 1311 extends from the opening of the mounting hole 131 along the height direction of the display panel 110, and the limiting groove 1312 extends along the circumferential direction O of the mounting hole 131 and communicates with the relief groove 1311. The outer peripheral surface 220a of the mounting post 220 is provided with a protrusion 221. The protrusion 221 is configured to enter the limiting groove 1312 along the relief groove 1311, and the limiting groove 1312 is configured to limit the displacement of the protrusion 221 along the circumferential direction O and the axial direction P of the mounting hole 131.

[0112] The display device 1000 disclosed in this application provides a clearance groove 1311 and a limiting groove 1312 communicating with the clearance groove 1311 in the mounting hole 131 of the rear housing 130. A protrusion 221 is provided on the mounting post 220 of the base 200. The protrusion 221 can enter the limiting groove 1312 along the clearance groove 1311. The limiting groove 1312 restricts the displacement of the protrusion 221 along the circumferential direction O and the axial direction P of the mounting hole 131. This makes the connection between the base 200 and the display device 100 more stable and reliable, effectively preventing the base 200 from loosening or falling off during use. At the same time, this connection method also has the advantages of simple and efficient assembly and disassembly. Users can install and remove the base 200 with a simple rotation operation, greatly improving the convenience of use. In addition, the design also hides the mounting posts 220 of the base 200 inside the mounting holes 131, thus concealing the mounting structure. This makes the design more concise and aesthetically pleasing, effectively avoiding the problem of the exposed mounting structure affecting the overall visual effect of the display device 1000.

[0113] See Figure 7 In some embodiments, the support leg 210 extends along the thickness direction X of the display panel 110. Two protrusions 221 are included, each located on one side of the outer peripheral surface 220a of the mounting post 220 along the width direction Y of the display panel 110. When the protrusion 221 enters the limiting groove 1312 along the relief groove 1311, that is, the base 200 is installed in the display device 100, the support leg 210 extends along the thickness direction X of the display panel 110 to support the display device 100. The two protrusions 221 are respectively located on both sides of the outer peripheral surface 220a of the mounting post 220 along the width direction Y of the display panel 110. That is, the arrangement direction of the two protrusions 221 on the outer peripheral surface 220a of the mounting post 220 is perpendicular to the extension direction of the support leg 210. This layout helps to further disperse the pressure of the display device 100 on the base 200, making the base 200 more evenly stressed, thereby improving the support stability and service life of the base 200.

[0114] Furthermore, since the arrangement direction of the two protrusions 221 on the outer peripheral surface 220a of the mounting post 220 is perpendicular to the extension direction of the support leg 210, on the one hand, when the display device 100 is subjected to forces from different directions, the two protrusions 221 can limit the mounting post 220 from different directions, enhancing the stability of the connection between the base 200 and the display device 100, and effectively preventing the display device 100 from shaking or displacing when subjected to external impacts; on the other hand, it can also provide intuitive guidance for installers, so that the extension direction of the support leg 210 naturally corresponds to the thickness direction X of the display panel 110, ensuring the accuracy of the installation orientation of the base 200 and avoiding structural stress concentration or decreased support stability caused by incorrect installation orientation.

[0115] Please see Figure 12 , Figure 12 This is a side view of the base provided in an embodiment of this application. In some embodiments, the support leg 210 includes a front support leg 211 and a rear support leg 212, both of which extend along the thickness direction X of the display panel 110. A mounting post 220 connects the front support leg 211 and the rear support leg 212. Along the thickness direction X of the display panel 110, the length of the front support leg 211 is greater than the length of the rear support leg 212.

[0116] By setting the length of the front support leg 211 along the thickness direction X of the display panel 110 to be greater than the length of the rear support leg 212 along the thickness direction X of the display panel 110, when the display device 1000 is subjected to external impact, it can not only play a role in buffering and stabilizing, but also further enhance the resistance when the display device 1000 tilts forward, reducing the possibility of tipping forward due to accidental collision. Specifically, since the display panel 110 of the display device 1000 is relatively fragile, when subjected to external impact from the rear, the longer front support leg 211 can provide a larger support area and a stronger anti-tipping moment, thereby effectively preventing the display device 1000 from tipping forward. Furthermore, when the display device 1000 is placed, its rear side is generally set against the wall. When the display device 1000 tilts backward, the wall can act as a stop, while when it tilts forward, it may fall directly to the ground and cause damage. Therefore, it is particularly important to set the length of the front support 211 along the thickness direction X of the display panel 110 to be greater than the length of the rear support 212 along the thickness direction X of the display panel 110 in order to prevent the display device 1000 from tilting forward.

[0117] For example, the structure of the front support 211 and the rear support 212 can be strip-shaped, block-shaped, column-shaped, etc., and the embodiments of this application do not limit this.

[0118] In some embodiments, the two protrusions 221 located on both sides of the outer peripheral surface 220a of the same mounting post 220 have different dimensions in the height direction of the display panel 110. By setting the two protrusions 221 on the same mounting post 220 to have different dimensions in the height direction of the display panel 110, the installer can distinguish the installation direction of the base 200 by the different protrusions 221 corresponding to different limiting grooves 1312 during the installation process, thereby avoiding installation errors caused by confusion.

[0119] Specifically, since the front support leg 211 and the rear support leg 212 of the support leg 210 have different sizes and their functions are also different, in order to make the front support leg 211 correspond to the front side of the display device 100 and the rear support leg 212 correspond to the rear side of the display device 100, when the two protrusions 221 have a size difference in the height direction, the installer can quickly determine the position where the protrusion 221 should be inserted into the corresponding limiting groove 1312 according to the size of the protrusion 221, thereby improving the installation efficiency and accuracy.

[0120] In some embodiments, a limiting protrusion (not shown) may be provided on the limiting groove 1312, and correspondingly, a limiting recess (not shown) may be provided on the protrusion 221. When the protrusion 221 enters the limiting groove 1312 along the relief groove 1311, the limiting protrusion and the limiting recess cooperate to limit the displacement of the protrusion 221 in the mounting hole 131 along its circumferential direction O. At the same time, the protrusion 221 entering the limiting groove 1312 can also limit the displacement of the protrusion 221 in the mounting hole 131 along its axial direction P. Thus, the connection between the base 200 and the display device 100 is more stable and reliable, effectively preventing the base 200 from becoming loose or falling off during use.

[0121] See again Figures 9 to 11 In other embodiments, the limiting groove 1312 includes a first sub-groove 1312a and a second sub-groove 1312b. The first sub-groove 1312a communicates with the clearance groove 1311, and the second sub-groove 1312b communicates with the first sub-groove 1312a. The dimension of the first sub-groove 1312a in the height direction of the display panel 110 is smaller than the dimension of the second sub-groove 1312b in the height direction of the display panel 110. The protrusion 221 includes a first sub-protrusion 2211 and a second sub-protrusion 2212. The second sub-protrusion 2212 is connected to the first sub-protrusion 2211, and the width of the first sub-protrusion 2211 in the height direction of the display panel 110 is smaller than the width of the second sub-protrusion 2212 in the height direction of the display panel 110.

[0122] In some embodiments, when the mounting post 220 rotates to allow the protrusion 221 to enter the limiting groove 1312, the second sub-protrusion 2212 abuts against the second sub-groove 1312b, and the first sub-protrusion 2211 abuts against the first sub-groove 1312a. The first sub-groove 1312a is configured to restrict the displacement of the second sub-protrusion 2212 along the circumferential direction O of the mounting hole 131. The first sub-groove 1312a and the second sub-groove 1312b are respectively configured to restrict the displacement of the first sub-protrusion 2211 and the second sub-protrusion 2212 along the axial direction P of the mounting hole 131.

[0123] By configuring the limiting groove 1312 to include a first sub-groove 1312a and a second sub-groove 1312b that are connected, and the dimension of the first sub-groove 1312a in the height direction of the display panel 110 is smaller than the dimension of the second sub-groove 1312b in the height direction of the display panel 110, and by configuring the protrusion 221 to include a first sub-protrusion 2211 and a second sub-protrusion 2212 that are connected, when the mounting post 220 extends into the mounting hole 131 along the relief groove 1311 and rotates, The second sub-protrusion 2212 abuts against the first sub-groove 1312a and the second sub-groove 1312b, and the first sub-protrusion 2211 abuts against the first sub-groove 1312a. This allows the first sub-groove 1312a to restrict the position of the second sub-protrusion 2212 along the circumferential direction O of the mounting hole 131. At the same time, the first sub-groove 1312a and the second sub-groove 1312b can also restrict the displacement of the first sub-protrusion 2211 and the second sub-protrusion 2212 along the axial direction P of the mounting hole 131, respectively.

[0124] This structural design further enhances the stability and reliability of the connection between the base 200 and the display device 100. In practical applications, the user simply aligns the mounting post 220 of the base 200 with the mounting hole 131 on the rear cover 130, and slides the protrusion 221 into the clearance groove 1311. Then, the user rotates the base 200 to allow the protrusion 221 to smoothly enter the limiting groove 1312, thus completing the installation of the base 200. For disassembly, the user rotates the base 200 in the opposite direction to allow the protrusion 221 to exit the limiting groove 1312 and slide out along the clearance groove 1311, making it easy to remove the base 200. This design not only simplifies operation but also effectively improves the user experience.

[0125] Please refer to it again. Figure 11 and Figure 12In some embodiments, a first guide surface 1312c connects the first sub-slot 1312a and the second sub-slot 1312b, and a second guide surface 2213 that mates with the first guide surface 1312c connects the first sub-protrusion 2211 and the second sub-protrusion 2212. The second sub-protrusion 2212 is configured to abut against the second sub-slot 1312b under the guidance of the first guide surface 1312c and the second guide surface 2213, thereby limiting the displacement of the second sub-protrusion 2212 along the circumferential direction O of the mounting hole 131.

[0126] By connecting a first guide surface 1312c between the first sub-slot 1312a and the second sub-slot 1312b, and correspondingly connecting a second guide surface 2213 between the first sub-protrusion 2211 and the second sub-protrusion 2212, with the second guide surface 2213 and the first guide surface 1312c engaging, the second sub-protrusion 2212 can abut against the second sub-slot 1312b under the guidance of the first guide surface 1312c and the second guide surface 2213, thereby limiting the displacement of the second sub-protrusion 2212 along the circumferential direction O of the mounting hole 131, and thus realizing the connection of the mounting post 220 in the mounting hole 131. This design of the first guide surface 1312c and the second guide surface 2213 makes the installation process smoother, reduces friction and resistance during installation, and improves installation efficiency. At the same time, the engagement of the first guide surface 1312c and the second guide surface 2213 also enhances the stability of the connection, making the connection between the base 200 and the display device 100 more secure and reliable.

[0127] For example, the shapes of the first guide surface 1312c and the second guide surface 2213 can be inclined surfaces, arc surfaces or stepped surfaces, etc., and the embodiments of this application do not limit this.

[0128] In some embodiments, the mounting post 220 includes a first post segment 222 and a second post segment 223. One end of the second post segment 223 is connected to the support leg 210, and the other end of the second post segment 223 is connected to the first post segment 222. The outer diameter of the first post segment 222 is smaller than the outer diameter of the second post segment 223. Both the first post segment 222 and the second post segment 223 are provided with protrusions 221, and along the height direction of the display panel 110, the protrusions 221 on the first post segment 222 and the protrusions 221 on the second post segment 223 are correspondingly arranged.

[0129] In some embodiments, the mounting hole 131 includes a first hole segment 1313 and a second hole segment 1314. The second hole segment 1314 is connected to the opening of the mounting hole 131, and the first hole segment 1313 is connected to the second hole segment 1314. The diameter of the first hole segment 1313 is smaller than the diameter of the second hole segment 1314. Both the first hole segment 1313 and the second hole segment 1314 are provided with a clearance groove 1311 and a limiting groove 1312. Along the height direction of the display panel 110, the clearance groove 1311 on the first hole segment 1313 is correspondingly provided with the clearance groove 1311 on the second hole segment 1314, and the limiting groove 1312 on the first hole segment 1313 is correspondingly provided with the limiting groove 1312 on the second hole segment 1314.

[0130] In some embodiments, the protrusion 221 of the first column segment 222 is configured to enter the limiting groove 1312 of the first hole segment 1313 along the clearance groove 1311 of the first hole segment 1313, and the protrusion 221 of the second column segment 223 is configured to enter the limiting groove 1312 of the second hole segment 1314 along the clearance groove 1311 of the second hole segment 1314.

[0131] It is understandable that the mating connection between the first column segment 222, the second column segment 223, and the first hole segment 1313 and the second hole segment 1314 makes the connection between the mounting post 220 and the mounting hole 131 more compact and stable. Due to its smaller outer diameter, the first column segment 222 can smoothly enter the smaller space formed by the first hole segment 1313, and its protrusion 221 engages with the limiting groove 1312 of the first hole segment 1313 to achieve axial and circumferential positioning along the mounting hole 131. Similarly, the second column segment 223, through its protrusion 221 engaging with the limiting groove 1312 of the second hole segment 1314, further enhances the stability of the mounting post 220 in the mounting hole 131. This segmented design not only improves the reliability of the connection but also makes the installation process more flexible and convenient. In practice, the installer can first align the first column segment 222 and insert it into the first hole segment 1313, then align the second column segment 223 and insert it into the second hole segment 1314, and finally rotate it to allow the protrusion 221 to smoothly enter the limiting groove 1312, thus completing the entire installation process. This design effectively avoids installation difficulties or unstable connections caused by improper fit between a single column segment and the inner wall surface 131a, and helps to improve the overall structural strength and stability of the display device 1000.

[0132] Of course, as in other embodiments, the mounting post 220 may include two post segments, or it may include three, four, five, or six post segments, and the inner wall surface 131a of the mounting hole 131 may also be configured accordingly as a segmented structure of the inner wall surface 131a matching the number of post segments of the mounting post 220. For example, when the mounting post 220 includes three post segments, the inner wall surface 131a of the mounting hole 131 may be configured as a first hole segment 1313, a second hole segment 1314, and a third inner wall surface 131a, with each inner wall surface 131a connected sequentially and its inner diameter adapted and adjusted according to the outer diameter of the corresponding post segment. Each column segment is provided with a protrusion 221, and along the height direction of the display panel 110, the protrusion 221 on each column segment is correspondingly set with the clearance groove 1311 and the limiting groove 1312 on the corresponding inner wall surface 131a. During installation, the protrusion 221 of each column segment enters the limiting groove 1312 along the corresponding clearance groove 1311, realizing a multi-segment tight connection between the mounting column 220 and the mounting hole 131. This multi-segment design can flexibly adjust the structure of the mounting column 220 and the mounting hole 131 according to the actual needs of the display device 1000, better adapt to display devices 100 of different sizes and weight distributions, further improve the stability and reliability of the connection between the base 200 and the display device 100, and at the same time provide more possibilities for the internal structural layout of the display device 1000, meeting diverse usage scenarios and design requirements.

[0133] In some embodiments, the length of the first column segment 222 is greater than the length of the second column segment 223 along the height direction of the display panel 110. By setting the length of the first column segment 222 along the height direction of the display panel 110 to be greater than the length of the second column segment 223 along the height direction of the display panel 110, the overall structural strength of the mounting post 220 can be ensured, while allowing the first column segment 222 to better penetrate into the mounting hole 131 and achieve a tighter fit with the first hole segment 1313. This design of length difference makes the force distribution of the mounting post 220 in the mounting hole 131 more reasonable. The first column segment 222 undertakes the main connection and positioning functions, while the second column segment 223 plays an auxiliary support and stabilizing role.

[0134] Specifically, when the display device 1000 is subjected to external force, the longer first column segment 222 can effectively disperse and transmit the force, reducing the risk of loosening or damage to the connection due to excessive local stress. Simultaneously, the presence of the second column segment 223 enhances the overall rigidity of the mounting column 220, preventing it from bending or deforming during stress, thus ensuring that the connection between the base 200 and the display device 100 remains stable and reliable. Furthermore, this length setting helps optimize the internal space layout of the display device 1000. Because the first column segment 222 is longer, its position in the mounting hole 131 can be adjusted more flexibly to accommodate internal functional components or wiring requirements of different sizes and shapes. The relatively shorter second column segment 223 does not excessively occupy or interfere with internal space, allowing the display device 1000 to maintain structural stability while having more internal space to arrange other key components, improving the overall performance and functional versatility of the device.

[0135] In some embodiments, the first column segment 222 includes a first end 222a and a second end 222b opposite to each other along the height direction of the display panel 110. The second column segment 223 includes a third end 223a and a fourth end 223b opposite to each other along the height direction of the display panel 110, with the third end 223a connected to the second end 222b and the fourth end 223b connected to the support leg portion 210. Both the first end 222a and the third end 223a are provided with protrusions 221. It can be understood that by providing protrusions 221 in both the first column segment 222 and the second column segment 223, it can be ensured that the mounting post 220 is positioned and connected to the inner wall surface 131a of the mounting hole 131 from two different height positions during insertion into the mounting hole 131. This design further enhances the connection stability between the mounting post 220 and the mounting hole 131, effectively preventing overall loosening due to the failure of a single connection point.

[0136] Furthermore, since the length of the first column segment 222 is greater than the length of the second column segment 223, a protrusion 221 is provided at the first end 222a of the first column segment 222 and a protrusion 221 is provided at the third end 223a of the second column segment 223. This creates a certain distance between the protrusions 221 of the two columns. During installation, this spacing design avoids interference caused by the two protrusions 221 simultaneously entering the same limiting groove 1312, ensuring smooth and accurate installation. Simultaneously, when the display device 1000 is subjected to external forces in different directions, the two protrusions 221 at different heights can respectively bear and disperse the force, making the connection between the mounting post 220 and the mounting hole 131 more stable and reliable, reducing the risk of loosening or damage due to uneven force.

[0137] Compared to setting the protrusion 221 at the second end 222b of the first column segment 222 and the fourth end 223b of the second column segment 223, the arrangement of this application is beneficial to enhance the torsional resistance of the mounting post 220 in the mounting hole 131. When the display device 1000 is subjected to lateral force or torque, the two protrusions 221 can form a tighter fit with the limiting groove 1312, effectively preventing the mounting post 220 from rotating relative to the mounting hole 131, thereby ensuring that the connection between the base 200 and the display device 100 remains stable at all times.

[0138] In some embodiments, the first column segment 222 and the second column segment 223 are both cylindrical segments, and the first column segment 222 and the second column segment 223 share a common center. The protrusion 221 on the first column segment 222 extends along the circumferential direction O of the first column segment 222, and the outer peripheral surface 220a of the protrusion 221 on the first column segment 222 is an arc surface. In the height direction of the display panel 110, the projection of the arc surface is located on the outer peripheral surface 220a of the second column segment 223.

[0139] The first column segment 222 and the second column segment 223 are designed as cylindrical segments with the same center. The protrusion 221 on the first column segment 222 extends circumferentially and the outer peripheral surface 220a is an arc surface. At the same time, the projection of the arc surface in the height direction of the display panel 110 is located on the outer peripheral surface 220a of the second column segment 223. That is, the radius of the circle corresponding to the arc surface of the protrusion 221 on the first column segment 222 is approximately the same as the radius of the second column segment 223. This makes it easier for the mounting post 220 to be inserted into the mounting hole 131, reducing installation difficulties or jamming caused by axial deviation. Installers can more easily align the mounting post 220 with the mounting hole 131, which helps to improve the installation efficiency of the display device 1000.

[0140] Secondly, the outer peripheral surface 220a of the protrusion 221 is curved, and its projection is located on the outer peripheral surface 220a of the second column segment 223. This design allows the protrusion 221 to make a closer fit with the limiting groove 1312. When the protrusion 221 enters the limiting groove 1312, the curved surface can better fit with the inner wall of the limiting groove 1312, increasing the contact area between the two and thus improving the stability of the connection between the base 200 and the display device 100. Moreover, when the display device 1000 is subjected to external force, this close-fitting connection method can effectively disperse the force and reduce the risk of loosening or damage to the connection due to excessive local force.

[0141] Furthermore, the concentric cylindrical segment structure makes the force on the mounting post 220 more even in the mounting hole 131. When the display device 1000 is subjected to external forces in different directions, the first post segment 222 and the second post segment 223 can share the force, avoiding structural damage caused by excessive force concentration on a certain post segment.

[0142] For example, the structure of the protrusion 221 can be a semi-circular protrusion, a rectangular protrusion, or a trapezoidal protrusion, etc., and the embodiments of this application do not limit it.

[0143] The following is a brief description of the detachable connection process between the display device 100 and the base 200 of this application:

[0144] Please see Figure 13 , Figure 13 This is a schematic diagram of the structure for inserting the mounting post 220 into the mounting hole along the clearance groove. First, align the mounting post 220 of the base 200 with the mounting hole 131 on the rear shell 130 of the display device 100. At this time, ensure that the protrusions 221 on the first post segment 222 and the second post segment 223 correspond to the clearance grooves 1311 of the first hole segment 1313 and the second hole segment 1314, respectively. Then, slowly insert the mounting post 220 along the axial direction P of the mounting hole 131. During insertion, the protrusions 221 on the first post segment 222 will slide along the clearance groove 1311 on the first hole segment 1313, and the protrusions 221 on the second post segment 223 will slide along the clearance groove 1311 on the second hole segment 1314. Since the outer peripheral surface 220a of the protrusion 221 is curved and its projection is located on the outer peripheral surface 220a of the second column segment 223, this design makes the contact between the protrusion 221 and the relief groove 1311 smoother, reducing friction and resistance, and allowing installers to push the mounting column 220 more easily.

[0145] When the mounting post 220 is inserted to a certain depth, the protrusion 221 on the first post segment 222 will reach the limiting groove 1312 on the first hole segment 1313, and the protrusion 221 on the second post segment 223 will reach the limiting groove 1312 on the second hole segment 1314. At this time, the installer rotates the base 200, causing the mounting post 220 to rotate within the mounting hole 131. During the rotation, the protrusion 221 on the first post segment 222 will gradually enter the limiting groove 1312 on the first hole segment 1313 along the first guide surface 1312c, and the protrusion 221 on the second post segment 223 will gradually enter the limiting groove 1312 on the second hole segment 1314 along the second guide surface 2213. Due to the cooperative design of the first guide surface 1312c and the second guide surface 2213, the protrusion 221 can smoothly enter the limiting groove 1312, and the first sub-groove 1312a will restrict the displacement of the second sub-protrusion 2212 along the circumferential direction O of the mounting hole 131. The first sub-groove 1312a and the second sub-groove 1312b will respectively restrict the displacement of the first sub-protrusion 2211 and the second sub-protrusion 2212 along the axial direction P of the mounting hole 131, thereby achieving a stable connection of the mounting post 220 in the mounting hole 131.

[0146] Please see Figure 14 , Figure 14 This is a schematic diagram illustrating the structure for rotating the mounting post to allow the protrusion 221 to enter the limiting groove. When the base 200 rotates to a certain angle, the protrusion 221 fully enters the limiting groove 1312, achieving a tight and secure connection between the base 200 and the display device 100. Installers can determine if the installation is complete by observing the relative position between the base 200 and the display device 100. If it is necessary to disassemble the base 200, installers simply need to rotate the base 200 in the opposite direction, causing the protrusion 221 to exit the limiting groove 1312 and slide out along the clearance groove 1311, allowing the base 200 to be easily removed.
