Description

Technical Field

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

[0002] The mechanical functions of a monitor can be mainly categorized into three types: tilt forward and backward, vertical rotation (or landscape / portrait switching), and height adjustment. Tilting forward and backward primarily accommodates different viewing angles, allowing users to adjust the monitor's angle according to their posture or usage scenario to reduce eye strain. Vertical rotation (landscape / portrait switching) allows users to switch the monitor from landscape to portrait mode as needed, which is particularly useful for browsing long web pages or editing documents. Height adjustment allows users to adjust the monitor's position according to their eye level, resulting in a more comfortable viewing experience.

[0003] However, existing monitor devices have not been designed with improvements in mind for customers working in a seated or standing position. Utility Model Content

[0058] This design allows the stand to be in its first position when the user is seated. At this position, the angle between the plane of the mounting plate and the horizontal plane is the third angle.

This fourth angle is greater than or equal to, and less than or equal to, the angle between the plane of the display screen (fixed to the mounting plate) and the horizontal plane. Therefore, the display screen is positioned approximately parallel to the horizontal plane, facilitating viewing for standing users. It should also be noted that the angle between the connecting rod in this second position and the horizontal plane D is the second angle. This means the connecting rod can bring the display screen closer to the horizontal plane, making it easier to view the screen while standing. Attached Figure Description

[0124] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0125] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0126] The mechanical functions that a monitor stand can perform can be mainly categorized into three types: tilting forward and backward, rotating vertically (or switching between portrait and landscape modes), and adjusting the height.

[0127] The forward and backward tilting features are primarily designed to accommodate different viewing angles. Users can adjust the monitor's angle according to their posture or usage scenario to reduce eye strain. This is typically achieved by installing a movable joint between the monitor base and stand, using a torsion spring or other form of friction device to provide appropriate resistance, allowing the monitor to tilt forward and backward within a certain range without moving arbitrarily. Additionally, to prevent safety hazards caused by excessive tilting, physical limiters are usually included.

[0128] Vertical rotation (landscape / portrait switching) allows users to switch the monitor from landscape to portrait mode as needed, which is particularly useful for browsing long web pages, editing documents, and other similar scenarios. This function relies on a rotating mechanism between the stand and the monitor, ensuring stable 90° rotation between them and maintaining stability after changing orientation.

[0129] Height adjustment allows users to adjust the monitor's position according to their eye level, resulting in a more comfortable viewing experience. This feature is typically achieved through a built-in gas spring, electric motor, or manual sliding rail system. A gas spring offers a simple and cost-effective solution, while an electric lift provides a smoother and more convenient operating experience.

[0130] However, existing monitor devices have not been designed to accommodate both seated and standing office work, especially the ability to raise or lower the screen height while rotating the monitor.

[0131] refer to Figures 1-5 As shown, this application proposes a display device, which includes a display screen 40 and a bracket. The bracket includes a chassis 20, a mounting plate 30, and a linkage device 10, and the display screen 40 is mounted on the mounting plate 30. The bracket provides power and signal connections to the display device.

[0132] It should be noted that the reference Figures 1-5 As shown, the linkage device 10 includes a first rotating shaft 100, a second rotating shaft 200, and a connecting rod 300. The connecting rod 300 is connected to the first rotating shaft 100 and the second rotating shaft 200 respectively. When the first rotating shaft 100 rotates, the connecting rod 300 can drive the second rotating shaft 200 to rotate, thereby switching between the first position A1 and the second position A2.

[0133] Among them, reference Figure 1 and Figure 2 As shown, the angle between the connecting rod portion 300 in the first position A1 and the horizontal plane D is the first angle α1, and the angle between the connecting rod portion 300 in the second position A2 and the horizontal plane D is the second angle α2. The first angle α1 is greater than the second angle α2. That is, when the connecting rod portion 300 turns from the first position A1 to the second position A2, the connecting rod portion 300 gradually moves closer to the horizontal plane D. This means that when the first position A1 is used, the distance between the connecting rod portion 300 supporting the display screen 40 and the desktop is L1. When the second position A2 is used, the distance between the connecting rod portion 300 supporting the display screen 40 and the desktop is L2. Wherein, distance L1 is greater than distance L2.

[0134] In summary, when the first rotating shaft 100 rotates, it can not only rotate itself, but also drive the second rotating shaft 200 to rotate, thereby driving the connecting rod 300 to switch from the first position A1 to the second position A2.

[0135] Furthermore, the mounting plate 30 is connected to the first rotating shaft 100, and the chassis 20 is connected to the second rotating shaft 200.

[0136] Based on the aforementioned linkage device 10, the bracket can be switched between a first position A1 and a second position A2. When the bracket is in the first position A1, the angle between the plane of the mounting plate 30 and the horizontal plane D is a third angle α3. When the bracket is in the second position A2, the angle between the plane of the mounting plate 30 and the horizontal plane D is a fourth angle α4.

[0137] Specifically, the third included angle α3 is greater than or equal to 80° and less than or equal to 100°, and the fourth included angle α4 is greater than or equal to 160° and less than or equal to 180°. For example, the third included angle α3 can be 80°, 85°, 90°, 95°, or 100°. The fourth included angle α4 can be 160°, 165°, 170°, 175°, or 180°.

[0138] Of course, in this embodiment, the bracket can be suspended at any angle between the third included angle α3 and the fourth included angle α4 in the first position A1 and the second position A2 to perform operations, thereby achieving more angle selection. For example, it can stop at any angle of 110°, 120°, 130°, 140°, or 150° between the third included angle α3 and the fourth included angle α4.

[0139] In summary, the display device proposed in this application, under the action of the linkage device 10, can not only rotate the angle of the display screen 40 when switching between the first position A1 and the second position A2, but also move the linkage 300 closer to the horizontal plane D. This provides the user with a better user experience.

[0140] Specifically, when the user sits down to work, the bracket is in the first position A1. At this time, the angle between the plane of the mounting plate 30 and the horizontal plane D is the third angle α3. That is, the angle between the plane of the display screen 40, which is fixed to the mounting plate 30, and the horizontal plane D is the third angle α3. The third angle α3 is greater than or equal to 80° and less than or equal to 100°. Therefore, the display screen 40 is within the 90° angle range perpendicular to the horizontal plane D, making it convenient for the user in a seated position to view the display screen 40. It should be noted that at this time, the angle between the connecting rod 300 in the first position A1 and the horizontal plane D is the first angle α1. That is, the connecting rod 300 can move the display screen 40 a certain distance from the horizontal plane D (desktop) to facilitate viewing the display screen 40 in a seated position.

[0141] When a user stands up to work, simply pressing the display screen 40 will position the bracket in the second position A2. At this point, the angle between the plane of the mounting plate 30 and the horizontal plane D is the fourth angle α4. This means the angle between the plane of the display screen 40, which is fixed to the mounting plate 30, and the horizontal plane D is the fourth angle α4, which is greater than or equal to 160° and less than or equal to 180°. Therefore, the display screen 40 is positioned approximately parallel to the horizontal plane D within a 180° angle range, facilitating viewing by a standing user. It should also be noted that the angle between the connecting rod 300 in the second position A2 and the horizontal plane D is the second angle α2. This means the connecting rod 300 can bring the display screen 40 closer to the horizontal plane D (desktop), making it easier to view the display screen 40 while standing.

[0142] Of course, when users switch from standing to sitting while working, they only need to adjust the display screen by 40.

[0143] In summary, when users change postures, such as from sitting to standing, they only need to press the display screen 40 to cause two changes in the display device. First, the angle of the display device relative to the horizontal plane D changes. Second, the height of the display device changes. These two changes make it convenient for users to view the content of the display screen 40 from different postures.

[0144] Based on the above settings, in one embodiment, reference is made to... Figure 1 and Figure 2 As shown, the first included angle α1 is set to be greater than or equal to 60° and less than or equal to 80°, and the second included angle α2 is set to be greater than or equal to 0° and less than or equal to 40°. For example, the first included angle α1 can be 60°, 65°, 70°, 75°, or 80°. The second included angle α2 can be 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, or 40°.

[0145] In one embodiment, reference Figures 5-12 As shown, the first rotating shaft portion 100 includes a first center 110 and a first eccentricity 120. The first rotating shaft portion 100 rotates along the first center 110, thereby causing the first eccentricity 120 to rotate along the first center 110. The second rotating shaft portion 200 includes a second center 210 and a second eccentricity 220. The second rotating shaft portion 200 rotates along the second center 210, thereby causing the second eccentricity 220 to rotate along the second center 210. The connecting rod portion 300 is connected to the first eccentricity 120 and the second eccentricity 220 respectively. The rotation of the first rotating shaft portion 100 along the first center 110 drives the connecting rod portion 300 to move through the first eccentricity 120, thereby causing the second eccentricity 220 to rotate, and further causing the second rotating shaft portion 200 to rotate along the second center 210. It should be noted that the first eccentricity 120 and the second eccentricity 220 are the connection points of the connecting rod portion 300, which are located at non-central positions of the first rotating shaft portion 100 and the second rotating shaft portion 200.

[0146] refer to Figures 10-12 As shown, when the first rotating shaft 100 rotates along the first center 110 in the direction Z1, the first eccentric 120 rotates accordingly. However, one end of the connecting rod 300 is connected to the first eccentric 120, and the other end is connected to the second eccentric 220. Therefore, the rotation of the first eccentric 120 causes the connecting rod 300 to move, which in turn causes the second eccentric 220 to rotate along the second center 210 in the direction Z2. At this time, under the influence of the first eccentric 120 and the second eccentric 220, the angle between the connecting rod 300 and the horizontal plane D changes from the first angle α1 to the second angle α2.

[0147] Based on the above configuration, the display device proposed in this application, under the action of the linkage device 10, can not only rotate the angle of the display screen 40 when switching between the first position A1 and the second position A2, but also move the linkage 300 closer to the horizontal plane D. This provides the user with a better user experience.

[0148] In one embodiment, reference Figure 10 As shown, let the plane where the connecting rod portion 300 is located be the first plane C, and let the line connecting the first center 110 to the first eccentric 120 on the first plane C be the first line C1. Let the line connecting the second center 210 to the second eccentric 220 on the first plane C be the second line C2. Set the first line C1 and the second line C2 parallel.

[0149] That is, at this time, the first rotating shaft 100 and the second rotating shaft 200 rotate at the same angle. When the connecting rod 300 is engaged, the corresponding first eccentric 120 and second eccentric 220 of the first rotating shaft 100 and the second rotating shaft 200 can be linked. This arrangement ensures that the first rotating shaft 100 and the second rotating shaft 200 rotate at the same angle under the drive of the connecting rod 300, thus facilitating control operation.

[0150] Further reference Figure 10 As shown, in this embodiment, the line connecting the first center 110 to the second center 210 on the first plane C is designated as the third line C3. The line connecting the first eccentricity 120 to the second eccentricity 220 on the first plane C is designated as the fourth line C4. The lengths of the third line C3 and the fourth line C4 are the same.

[0151] like Figure 10 As shown, the first line C1, the second line C2, the third line C3, and the fourth line C4 together form a parallelogram. That is, the rotation of the first rotating shaft 100 can be completely transferred to the second rotating shaft 200 via the connecting rod 300, allowing it to perform the same action. This achieves the goal that when the first rotating shaft 100 rotates, the angle between the connecting rod 300 and the horizontal plane D changes from the first angle α1 to the second angle α2.

[0152] In one embodiment, reference Figure 10 As shown, when the connecting rod portion 300 is in the second position A2, on the first plane C, the first eccentric 120 is disposed below the first center 110 along the vertical direction Y, and on the first plane C, the second eccentric 220 is disposed below the second center 210 along the vertical direction Y. In the second position A2, both the first eccentric 120 and the second eccentric 220 are disposed below the first center 110 and the second center 210, respectively; that is, the connecting rod portion 300 is disposed below the first rotating shaft portion 100 and the second rotating shaft portion 200.

[0153] Based on the above configuration, the connecting rod 300 can provide good support for the first pivot 100, the second pivot 200, and the components located on the first pivot 100 and the second pivot 200. On the other hand, the second pivot 200 can be housed within the chassis 20, thereby making the overall display device more aesthetically pleasing.

[0154] In this embodiment, reference Figure 10 As shown, when the connecting rod portion 300 is in the first position A1, the first eccentric 120 is disposed on the side of the first center 110 along the horizontal direction X, and the second eccentric 220 is disposed on the side of the second center 210 along the horizontal direction X. It should be noted that the side can be understood as a position that is neither located at the top nor at the bottom.

[0155] Similarly, the first eccentricity 120 is disposed on the side of the first center 110 along the horizontal direction X, allowing the connecting rod portion 300 to apply tension from the side. Furthermore, since the first eccentricity 120 is disposed on the side of the first center 110 along the horizontal direction X, and the second eccentricity 220 is disposed on the side of the second center 210 along the horizontal direction X, the connecting rod portion 300 can be at least partially hidden behind the display screen 40, resulting in a more aesthetically pleasing appearance.

[0156] In one embodiment, reference Figure 4 As shown, the linkage device 10 includes a rotating housing 400, and a first rotating shaft 100 and a second rotating shaft 200 are respectively rotatably mounted on the rotating housing 400.

[0157] The rotating housing 400 includes a first receiving space 410, and the connecting rod portion 300 is disposed in the first receiving space 410.

[0158] The rotating housing 400 provides a mounting space for the connecting rod portion 300, thus isolating it from the outside environment and preventing external contamination. It also enhances the overall strength of the connecting rod portion 300, providing better support for the first rotating shaft portion 100, the mounting plate 30 on the first rotating shaft portion 100, and the display screen 40.

[0159] In one embodiment, reference Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, the rotating housing 400 includes a first blocking wall 411 and a second blocking wall 412 forming a first receiving space 410, with the first blocking wall 411 and the second blocking wall 412 arranged opposite to each other. It should be noted that the first blocking wall 411 and the second blocking wall 412 are arranged opposite to each other with a certain distance between them and are arranged parallel to each other.

[0160] When the connecting rod portion 300 is in the first position A1, the connecting rod portion 300 is fitted with the first blocking wall 411. When the connecting rod portion 300 is in the second position A2, the connecting rod portion 300 is fitted with the second blocking wall 412.

[0161] Based on the above configuration, on the one hand, the connecting rod 300 can be in contact with the wall of the first accommodating space 410 in both the first position A1 and the second position A2, thereby minimizing the space occupied by the first accommodating space 410 while maintaining the normal operation of the linkage device 10. On the other hand, in the first position A1 and the second position A2, the first blocking wall 411 and the second blocking wall 412 can partially limit the rotation, stopping the rotation at the corresponding first position A1 and second position A2. Of course, this application can not only set it to be stationary in the first position A1 and the second position A2, but also generate partial damping in the first position A1 and the second position A2, requiring the user to apply greater force to further rotate the first rotating shaft 100 and the second rotating shaft 200.

[0162] Meanwhile, under the above embodiment settings, in other embodiments, it can be configured such that when the connecting rod portion 300 is in the first position A1, the connecting rod portion 300 is in contact with the first blocking wall 411. Simultaneously, when the connecting rod portion 300 is in the second position A2, the connecting rod portion 300 is not in contact with the second blocking wall 412. Alternatively, when the connecting rod portion 300 is in the first position A1, it is not in contact with the first blocking wall 411. Simultaneously, when the connecting rod portion 300 is in the second position A2, it is in contact with the second blocking wall 412. Or, when the connecting rod portion 300 is in the first position A1, it is not in contact with the first blocking wall 411. Simultaneously, when the connecting rod portion 300 is in the second position A2, it is also not in contact with the second blocking wall 412. That is, in both the first position A1 and the second position A2, it does not contact the rotating housing 400. All of the above embodiments are within the protection scope of this application.

[0163] In one embodiment, reference Figures 5-9 As shown, the connecting rod portion 300 includes a first fitting portion 310, a connecting portion 320, and a second fitting portion 330 connected in sequence. The first fitting portion 310 and the second fitting portion 330 are positioned differently in the width direction E of the first receiving space 410. That is, the first fitting portion 310 and the second fitting portion 330 are not on the same straight line, and they are connected by a connecting portion 320 that is spaced apart in the width direction E.

[0164] When the connecting rod portion 300 is in the first position A1, the first fitting portion 310 is fitted with the first blocking wall 411. When the connecting rod portion 300 is in the second position A2, the second fitting portion 330 is fitted with the second blocking wall 412.

[0165] Based on the above configuration, the connecting part 320 connects the first fitting part 310 and the second fitting part 330, and transmits the rotation and displacement of the first rotating shaft part 100 to the second rotating shaft part 200 through the first fitting part 310, the connecting part 320 and the second fitting part 330.

[0166] In some embodiments, reference Figure 4 , Figure 5 as well as Figure 6 As shown, the connecting rod portion 300 includes a bent rod area 340, and the rotating housing 400 includes a bent shell area 420. A bending space 421 is correspondingly provided within the bent shell area 420, and the bent rod area 340 is disposed within the bending space 421. It should be noted that the bending angle of the bent shell area 420 is set to be greater than or equal to 40° and less than or equal to 130°. For example, the bending angle of the bent shell area 420 can be 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, or 130°.

[0167] Based on the above configuration, the connecting rod portion 300 can rotate and move within the bent housing region 420 when the first rotating shaft portion 100 is in operation, thereby driving the second rotating shaft portion 200 to rotate and move. Furthermore, the bent housing region 420 of the rotating housing 400 can protect the bent rod region 340.

[0168] In this embodiment, reference Figures 5-8 As shown, the bending space 421 is enclosed by the third blocking wall 422. When the connecting rod portion 300 is in the second position A2, the bending rod area 340 is in contact with the third blocking wall 422. Of course, in other embodiments, the bending rod area 340 and the third blocking wall 422 may not be in contact.

[0169] Based on the above configuration, in this embodiment, when the connecting rod portion 300 is in the second position A2, the bent rod area 340 is fitted against the third blocking wall 422. This serves a positioning function; that is, when the user moves the linkage device 10 from the first position A1 to the limit of the second position A2, the fit occurs, thereby achieving the positioning effect.

[0170] In one embodiment, reference Figure 7 and Figure 13As shown, the rotating housing 400 includes a second accommodating space 430, which is isolated from the first accommodating space 410, that is, the second accommodating space 430 and the first accommodating space 410 are not connected. The second accommodating space 430 is used to arrange connecting lines.

[0171] By setting up the second accommodating space 430 and the first accommodating space 410, the connecting wire and the connecting rod 300 can be arranged separately, thereby avoiding the connecting wire from getting tangled on the connecting rod 300 when switching between the first position A1 and the second position A2, thus reducing the risk of damage to the connecting wire.

[0172] In one embodiment, reference Figure 2 , Figure 7 , Figure 10 as well as Figure 13 As shown, the first rotating shaft portion 100 includes a plurality of first rotating shaft units 130, which are arranged in a straight line in the horizontal direction X. Each of the first rotating shaft units 130 includes a first center 110 and a first eccentricity 120. On the first plane C, the line connecting the first center 110 and the first eccentricity 120 of the plurality of first rotating shaft units 130 is a first line C1, and the plurality of first lines C1 are arranged parallel to each other. That is, the plurality of first rotating shaft units 130 are arranged on the same horizontal line, and the deflection angles of the corresponding first eccentricities 120 are all the same. In this embodiment, the number of second rotating shaft portions 200 is not limited. There can be one or more second rotating shaft portions 200 corresponding to the first rotating shaft units 130, as long as they can be adapted to the first rotating shaft units 130, they are all within the protection scope of this application.

[0173] Based on the above configuration, on the one hand, providing multiple first pivot units 130 can increase the corresponding connecting rod portions 300 to support the mounting plate 30 and display screen 40 located on the first pivot portion 100. On the other hand, setting multiple first pivot units 130 to the same angle facilitates user operation, and when rotating one first pivot unit 130, all first pivot units 130 can perform the same operation.

[0174] In one embodiment, reference Figure 2 , Figure 7 , Figure 10 as well as Figure 13 and Figure 14As shown, the second rotating shaft portion 200 includes a plurality of second rotating shaft units 230, which are arranged in a straight line in the horizontal direction X. Each of the second rotating shaft units 230 includes a second center 210 and a second eccentricity 220. On the first plane C, the line connecting the second center 210 and the second eccentricity 220 of the plurality of second rotating shaft units 230 is a second line C2, and multiple second lines C2 are arranged parallel to each other. That is, the plurality of second rotating shaft units 230 are arranged on the same horizontal line, and the deflection angles of the corresponding second eccentricities 220 are all the same. In this embodiment, the number of second rotating shaft units 230 is not limited; there can be one or more second rotating shaft units 230, as long as they can be adapted to the second rotating shaft units 230, they are all within the scope of protection of this application.

[0175] Based on the above configuration, on the one hand, setting multiple second pivot units 230 can increase the corresponding connecting rods 300 for support, thereby making the entire display device more stable. On the other hand, setting multiple second pivot units 230 at the same angle facilitates user operation, and when rotating one second pivot unit 230, all second pivot units 230 can perform the same operation.

[0176] In summary, the number of both the first rotating shaft unit 130 and the second rotating shaft unit 230 can be set to multiple. The multiple first rotating shaft units 130 are arranged in a straight line in the horizontal direction X, and each of the multiple first rotating shaft units 130 includes a first center 110 and a first eccentricity 120. On the first plane C, the line connecting the first center 110 and the first eccentricity 120 of the multiple first rotating shaft units 130 is a first line C1, and multiple first lines C1 are arranged parallel to each other. Similarly, the multiple second rotating shaft units 230 are arranged in a straight line in the horizontal direction X, and each of the multiple second rotating shaft units 230 includes a second center 210 and a second eccentricity 220. On the first plane C, the line connecting the second center 210 and the second eccentricity 220 of the multiple second rotating shaft units 230 is a second line C2, and multiple second lines C2 are arranged parallel to each other. Furthermore, the first lines C1 and the second lines C2 are set to be parallel.

[0177] Based on the above configuration, the multiple first pivot units 130 and the multiple second pivot units 230 can enable the display device to achieve better stability.

[0178] In one embodiment, the linkage device 10 includes a linkage rod (not shown in the figure), which connects to a plurality of first rotating shaft units 130 along a first center 110, so that the plurality of first rotating shaft units 130 rotate synchronously. That is, the plurality of first rotating shaft units 130 rotate directly through a linkage rod.

[0179] Based on the above configuration, on the one hand, a more precise transmission can be achieved by rotating directly through a single linkage. On the other hand, multiple first rotating shaft units 130 are directly connected by a single linkage, thereby achieving better stability.

[0180] Similarly, in another embodiment, a linkage rod can be designed, and the linkage rod can be connected to multiple second rotating shaft units 230 along the second center 210, so that the multiple second rotating shaft units 230 rotate synchronously. That is, the multiple second rotating shaft units 230 rotate directly through a linkage rod.

[0181] Based on the above configuration, on the one hand, a more precise transmission can be achieved by rotating directly through a single linkage. On the other hand, multiple second rotating shaft units 230 are directly connected by a single linkage, thereby achieving better stability.

[0182] In summary, multiple linkages can be provided in a single display device, with multiple first rotating shaft units 130 rotating via the linkages and multiple second rotating shaft units 230 rotating via the linkages. All of the above configurations are within the scope of protection of this application.

[0183] refer to Figure 13 and Figure 14 As shown, the chassis 20 includes a rotation space 21, and the linkage device 10 includes a rotating housing 400. The rotating housing 400 includes a first receiving space 410, and the connecting rod portion 300 is disposed in the first receiving space 410. At least a portion of the rotating housing 400 is disposed in the rotation space 21.

[0184] Based on the above configuration, the rotating housing 400 can be rotated within the rotating space 21 to ensure the basic transition between the first position A1 and the second position A2. Furthermore, the rotating space 21 allows the bottom of the rotating housing 400 to be positioned within it, thus improving the aesthetics of the bracket.

[0185] In one embodiment, the inner wall of the rotating space 21 forms an angled region with the outer surface of the chassis 20 (not shown in the figure). The rotating housing 400 includes a bent shell region 420, the angle of which is the same as the angle of the included angle region. When the connecting rod portion 300 is in the second position A2, the bent shell region 420 is in contact with the included angle region. That is, when the connecting rod portion 300 is in the second position A2, it can partially contact the chassis 20, thereby obtaining a supporting force. Furthermore, since the angle of the bent shell region 420 is the same as the angle of the included angle region, when the rotating housing 400 rotates, it can rotate to the maximum angle (the angle of contact) without interfering with the outer surface of the chassis 20.

[0186] In one embodiment, the bracket includes connecting wires disposed in the second receiving space 430 and connected to the chassis 20 and the mounting plate 30, respectively.

[0187] By providing a second receiving space 430 and a first receiving space 410, the connecting wire and the connecting rod 300 can be arranged separately, thereby preventing the connecting wire from getting tangled on the connecting rod 300 when switching between the first position A1 and the second position A2, thus reducing the risk of damage to the connecting wire. Furthermore, the connecting wire of this device passes through the rotating housing 400 to connect the chassis 20 and the mounting plate 30, thus ensuring the aesthetics of the display device.

[0188] refer to Figure 7 and Figure 11 As shown, the bracket includes a first power unit 24 and a first limiting block 25. The first power unit 24 is disposed on the mounting plate 30 and is connected to the first rotating shaft 100. The first power unit 24 is used to provide power to the first rotating shaft 100. The first limiting block 25 is disposed on the first rotating shaft 100 and is used to limit the rotation of the first rotating shaft 100.

[0189] With the above settings, when the user adjusts the display screen 40 to a certain angle, the first limit block 25 is used to limit the angle rotation of the display screen 40, and the first power unit 24 will output power in the opposite direction to prevent the first rotating shaft 100 from automatically returning to its original position, thereby making it more convenient for the user to use.

[0190] refer to Figure 14 As shown, the bracket also includes a second power unit 26 and a second limiting block 27. The second power unit 26 is disposed on the chassis 20 and is connected to the second rotating shaft 200. The second power unit 26 is used to provide power to the second rotating shaft 200. The second limiting block 27 is disposed on the second rotating shaft 200 and is used to limit the rotation of the second rotating shaft 200.

[0191] Similarly, when the user adjusts the display screen 40 to a certain angle, the second limiting block 27 restricts the rotation of the display screen 40, and the second power unit 26 outputs power in the opposite direction to prevent the second rotating shaft 200 from automatically returning to its original position, thus making it more convenient for the user to use. In addition, the second rotating shaft 200 in this application is located at the lower part of the bracket, and multiple second power units 26 can be installed for power balance.

[0192] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
