In the detailed description of the present application below, certain specific details are described in detail. Those skilled in the art can fully understand the present application without these details. To avoid obscuring the substance of the present application, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0035] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0036] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0037] This utility model relates to a display device, see below. Figure 1 and Figure 2 The display device includes a support assembly 1, a tilt adjustment assembly 2, a swivel adjustment assembly 3, and a display screen 4. The support assembly 1 includes a base 11, a column 12, and a connecting beam 13, with the lower end of the column 12 connected to the base 11. Optionally, the column 12 can be perpendicular to the base 11. (See reference...) Figures 2-4 The connecting beam 13 has a first connecting end 131 and a second connecting end 132 arranged opposite to each other. The first connecting end 131 is connected to the column 12, and the second connecting end 132 is connected to the tilt adjustment component 2. As shown in the figure, the display screen 4 has a front side 41 and a back side 42 arranged opposite to each other. The back side 42 of the display screen 4 is connected to the second connecting end 132 through the rotation adjustment component 3 and the tilt adjustment component 2, thereby realizing the support component 1 supporting the display screen 4. In some usage scenarios, the base 11 can be placed on a nearly horizontal surface, such as on the ground or a table.

[0038] Figures 3-11 The structures of the rotation adjustment assembly 3 and the pitch adjustment assembly 2 are shown, wherein Figure 10 The cross-sectional position is Figure 5 plane AA in Figure 11 The cross-sectional position is Figure 5 BB plane in Figure 7 yes Figure 6 A magnified view of part C in the diagram. Figure 9 yes Figure 8A magnified view of section D in the diagram. (Refer to...) Figures 3-11 The rotation adjustment component 3 is used to adjust the angle of the display screen 4 relative to the display screen 4. For example... Figure 10 As shown, the rotation adjustment assembly 3 includes a display screen mounting bracket 31 and a second connector 32. The display screen mounting bracket 31 is used to connect to the display screen 4, and the second connector 32 includes a second rotating shaft 321. The display screen mounting bracket 31 is rotatably connected to the adapter 21 through the second connector 32. After the display screen 4 is mounted on the display screen mounting bracket 31, its position relative to the display screen mounting bracket 31 is fixed. When the display screen mounting bracket 31 rotates around the second rotating shaft 321, the display screen 4 also rotates around the second rotating shaft 321. The second rotating shaft 321 is perpendicular to the first rotating shaft 221, and the second rotating shaft 321 can be substantially perpendicular to the display screen 4, so that the display screen 4 can be adjusted in circumferential angle through the rotation adjustment assembly 3, for example, to achieve switching between landscape and portrait modes.

[0039] The tilt adjustment component 2 is used to adjust the tilt angle of the display screen 4 relative to the support component 1. (See reference...) Figures 3-11 The pitch adjustment assembly 2 includes an adapter 21 and a first connector 22, wherein the adapter 21 is used to connect the second connecting end 132 and the rotation adjustment assembly 3. The first connector 22 includes a first rotating shaft 221, which is substantially parallel to the base 11, that is, when the base 11 is set on a horizontal plane, the first rotating shaft 221 is substantially a horizontal axis. The adapter 21 is rotatably connected to the second connecting end 132 through the first connector 22. The adapter 21 can rotate around the first rotating shaft 221. When the angle of the adapter 21 relative to the second connecting end 132 is adjusted, the display screen 4 also rotates around the first rotating shaft 221, thereby adjusting the pitch angle of the display screen 4.

[0040] Optionally, the first connector 22 includes a first damping structure, which provides damping force when the adapter 21 rotates about the first pivot 221 relative to the first connecting end 131, so that the display screen 4 can be held at that angle and hovered after the circumferential angle adjustment is completed, facilitating user operation. The second connector 32 may also include a second damping structure, which provides damping force when the adapter 21 rotates about the second pivot 321 relative to the second connecting end 132, so that the display screen 4 can be held at that angle and hovered after the pitch angle adjustment is completed, facilitating user operation. The first or second damping structure can be any device suitable for providing damping force during relative rotation, such as a friction damping device, an electromagnetic damping device, a hydraulic damping device, etc.

[0041] In this embodiment, the second connecting end 132 has a first limiting structure, and the adapter 21 has a second limiting structure corresponding to the first limiting structure. The first limiting structure and the second limiting structure cooperate to limit the pitch angle adjustment range of the display screen 4 around the first rotating axis 221. The pitch angle adjustment range of the display screen 4 around the first rotating axis 221 is greater than 90 degrees, and the display screen 4 is parallel to the base 11 in at least one position (e.g., ...). Figure 6 (As shown). When the display screen 4 is in a basically flat state, it forms a desktop-like state, which helps to broaden the usage scenarios. For example, when the display screen 4 is a touch screen, when the display screen 4 is flat, it is convenient for users to use the touch screen 4 to perform operations such as games and drawing.

[0042] Reference Figures 6-9 In some embodiments, the first limiting structure is a limiting pin 1321, and the second limiting structure is a limiting groove 211, which has a first sidewall 2111 and a second sidewall 2112 disposed opposite to each other. When the adapter 21 rotates relative to the connecting beam 13, the limiting pin 1321 moves between the first sidewall 2111 and the second sidewall 2112. The positions of the first sidewall 2111 and the second sidewall 2112 are set according to the required tilt angle adjustment range of the display screen 4. For example, refer to... Figure 6 and Figure 7 When the limiting pin 1321 abuts against the first sidewall 2111, the front surface 41 of the display screen 4 is away from the base 11 and is substantially parallel to the base 11. As the limiting pin 1321 moves from the first sidewall 2111 to the second sidewall 2112, the angle between the front surface 41 of the display screen 4 and the base 11 gradually decreases. Optionally, referring to… Figure 8 and Figure 9 When the limiting pin 1321 abuts against the second side wall 2112, the front 41 of the display screen 4 can tilt slightly downward to accommodate users who are shorter or have a lower viewing position. Setting the first limiting structure as the limiting pin 1321 and the second limiting structure as the limiting groove 211 is only one feasible implementation. The forms of the first and second limiting structures can also be set to other forms according to actual needs.

[0043] In some embodiments, the connecting beam 13 can be substantially parallel to the base 11. When the limiting pin 1321 abuts against the first sidewall 2111, the back surface 42 of the display screen 4 is close to the top of the connecting beam 13. The connecting beam 13 can also limit and support the flattened display screen 4.

[0044] In this embodiment, the adapter 21 has a base plate 212 and two first ear plates 213, which are arranged opposite to each other at a distance, and the base plate 212 is connected between the two first ear plates 213. For example, refer to Figure 3The second limiting structure is located on the first ear plate 213, the second connecting end 132 is connected to the two first ear plates 213, and the display screen mounting bracket 31 is connected to the base plate 212.

[0045] Reference Figure 11 The second connecting end 132 has a first connecting hole 1322, and the first ear plate 213 has a second connecting hole 2131. The second connecting end 132 is located between the two first ear plates 213. The second rotating shaft 321 passes through the second connecting holes 2131 on the two first ear plates 213 and the first connecting hole 1322 on the second connecting end 132, connecting the two ear plates to the second connecting end 132. In one embodiment, the second connecting end 132 has two opposing second ear plates 1323, each corresponding to a first ear plate 213. Each second ear plate 1323 is located close to a first ear plate 213 and has a first connecting hole 1322. The second rotating shaft 321 connects the first ear plates 213 and the second ear plates 1323 in series. The first rotating shaft 221 can be a screw. After the first rotating shaft 221 passes through the adapter 21 and the second connecting end 132, it is locked by a nut. The squeezing friction between the first connecting ear and the second connecting ear can provide a certain damping force during the pitch angle adjustment process.

[0046] In some embodiments, refer to Figure 5 , Figure 10 and Figure 11 The pitch adjustment assembly 2 also includes a torsion spring 23, which is disposed between the two second lugs 1323 and sleeved outside the first rotating shaft 221. The torsion spring 23 has two opposing free ends 231, one of which is connected to the second connecting end 132, and the other free end 231 is connected to the adapter 21. Optionally, as... Figure 11 As shown, the second connecting end 132 has a positioning groove 1324, and a free end 231 of the torsion spring 23 is positioned in the positioning groove 1324. The torsion spring 23 can be used to provide damping force for the tilt angle adjustment of the display screen 4. When the tilt angle of the display screen 4 is adjusted to the required position, the weight of the display screen 4 and the damping force provided by the torsion spring 23 are balanced, so that the display screen 4 can be suspended at the preset tilt angle position.

[0047] In some embodiments, refer to Figure 10 and Figure 11The first connecting member 22 further includes a connecting cylinder 222, which is disposed between the two second ear plates 1323. Optionally, the length of the connecting cylinder 222 can match the distance between the two second ear plates 1323, thereby allowing it to be supported between the two second ear plates 1323. The connecting cylinder 222 has a mounting hole 2221, the diameter of which matches the size of the first rotating shaft 221. The first rotating shaft 221 passes through the mounting hole 2221, and the torsion spring 23 is sleeved on the outside of the connecting cylinder 222. By providing the connecting cylinder 222, the assembly of the pitch adjustment assembly 2 can be facilitated, and the structural stability of the pitch adjustment assembly 2 can be enhanced.

[0048] In some embodiments, refer to Figure 2 and Figure 12 The column 12 can be configured as a telescopic structure, thereby enabling the display screen 4 to be raised and lowered. In one embodiment, the column 12 includes a sleeve 121 and a telescopic component 122. The lower end of the sleeve 121 is connected to the base 11, and the sleeve 121 has a cavity inside, in which the telescopic component 122 is disposed. Optionally, the telescopic component 122 includes a gas spring 1221 and a lifting bracket 1222. The gas spring 1221 is disposed below the lifting bracket 1222 and one end is fixed relative to the base 11. The other end of the gas spring 1221 is connected to the lower end of the lifting bracket 1222, and the upper end of the lifting bracket 1222 is connected to the first connecting end 131 of the connecting beam 13. The gas spring 1221 is a device that uses high-pressure gas in a sealed container and piston movement to generate damping force. The gas spring 1221 can also achieve hovering at a specific position. When the gas spring 1221 is compressed or stretched to a certain position, the internal pressure balance allows it to hover at that position, remaining stationary and not moving due to slight changes in external force. Using the gas spring 1221, convenient and reliable height adjustment of the display screen 4 can be achieved.

[0049] To achieve stable height adjustment of the display screen 4, in some embodiments, refer to Figure 12 The telescopic assembly 122 also includes a guide member 1223. The guide member 1223 is connected to the lifting bracket 1222 and contacts the inner surface of the sleeve 121, thereby ensuring the stability of the lifting bracket 1222 during movement within the sleeve 121 and preventing radial swaying. In one feasible embodiment, the guide member 1223 can be configured as a ring structure, sleeved around the lifting bracket 1222 and contacting the inner surface of the sleeve 121. When the lifting bracket 1222 rises and falls within the sleeve 121, the outer surface of the sliding sleeve slides relative to the inner surface of the sleeve 121, which not only maintains the stability of the lifting bracket 1222's movement but also provides a certain damping force to ensure the hovering effect of the lifting bracket 1222.

[0050] The side wall of the sleeve 121 also has a through guide hole 1211. The connecting beam 13 passes through the guide hole 1211. The length direction of the guide hole 1211 is parallel to the extension direction of the telescopic assembly 122. The first connecting end 131 extends from the guide hole 1211 into the cavity and connects to the lifting bracket 1222. When the display screen 4 and the connecting beam 13 are raised and lowered, the connecting beam 13 moves up and down in the guide hole 1211. The guide hole 1211 can prevent the position of the connecting beam 13 from swaying.

[0051] The display device of this utility model embodiment can be applied to various devices with image display functions. Additionally, optionally, the display device may also include a speaker for playing audio, a microphone for collecting sound signals, etc. In some application scenarios, the display device can be a smart portable screen, and may include one or more functions such as displaying images and text, playing video and audio, and running computer applications.

[0052] This utility model provides a display device, which includes a support assembly 1, a pitch adjustment assembly 2, a rotation adjustment assembly 3, and a display screen 4. The display screen 4 is connected to the support assembly 1 through the pitch adjustment assembly 2 and the rotation adjustment assembly 3, enabling adjustment of the rotation and pitch angles of the display screen 4. A first limiting structure on the second connecting end 132 of the connecting beam 13 of the support assembly 1 cooperates with a second limiting structure on the adapter seat 21 of the pitch adjustment assembly 2 to limit the pitch angle adjustment range of the display screen 4, allowing the display screen 4 to be parallel to the base 11 in at least one position, thus expanding the application scenarios of the display screen 4. Furthermore, the pitch adjustment assembly 2 and the rotation adjustment assembly 3 of the display device have simple and reliable structures, are easy to install and maintain, and help reduce costs.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
