Over time, the belt may loosen and slip, causing deviations in the rotation angle of the TV stand and causing significant inconvenience to customers. In addition, the rotation mechanism of current rotating monitor stands uses ball bearings, which have poor shear resistance and are easily damaged, especially during reciprocating rotation.

The specific implementation of this utility model is described in more detail below with reference to specific embodiments:

[0037] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides a monitor stand, comprising:

[0038] The rotating assembly 1 includes a rotating fixed component 11, a rotating component 12, and a thrust bearing 13 that rotatably connects the rotating fixed component 11 and the rotating component 12. The rotating component 12 can rotate about the axis of the rotating fixed component 11 through the thrust bearing 13.

[0039] The lifting assembly 2 includes a lifting and fixing component 21 connected to the rotating component 12, a lifting component 22 rotatably connected to the lifting and fixing component 21, and a push rod 23 that telescopically connects the lifting and fixing component 21 and the lifting component 22. The lifting component 22 can lift relative to the lifting and fixing component 21 through the push rod 23.

[0040] Hanger assembly 3 is mounted on lifting component 22 and is used to install the monitor.

[0041] Specifically, the monitor stand includes a rotating component 1, a lifting component 2, and a hanging bracket component 3.

[0042] In the rotating assembly 1, the rotating fixed component 11 plays a basic fixing role, while the rotating component 12 is the key part to realize the rotation function, and the thrust bearing 13 rotatably connects the two. Its working principle is as follows: when an external force is applied to the rotating component 12, due to the presence of the thrust bearing 13, the rotating component 12 can rotate smoothly around the axis of the rotating fixed component 11. The balls of the thrust bearing 13 roll in the raceway, which greatly reduces the friction during rotation and makes the rotation more flexible.

[0043] In lifting assembly 2, the lifting fixed component 21 is connected to the rotating component 12, providing basic support for the lifting function. The lifting component 22 is rotatably connected to the lifting fixed component 21, and works with the push rod 23 to achieve extension and retraction. The working method of the push rod 23 determines the lifting function. If it is an electric push rod 23, the motor drives the lead screw and nut pair, converting the rotational motion of the motor into linear motion, pushing the lifting component 22 to rise or fall relative to the lifting fixed component 21. If it is a mechanical structure such as a spring pneumatic rod, the elastic potential energy of the spring is used to achieve lifting and support the weight of the display.

[0044] The mounting bracket 3 is installed on the lifting component 22 and is used to mount the monitor.

[0045] By adopting the above technical solution, in terms of rotation control, a thrust bearing 13 is used to connect the rotating fixed component 11 and the rotating component 12, eliminating the rotation angle deviation problem caused by belt loosening and slippage in traditional technology. This ensures accurate rotation positioning of the monitor and maintains stable rotation performance even after long-term use. In terms of the reliability of the rotation mechanism, the thrust bearing 13 replaces the ball bearing with poor shear resistance. Its bidirectional thrust structure can effectively withstand axial loads, significantly improving the durability of the rotating component 1 when the monitor rotates frequently, reducing the risk of component damage, and lowering maintenance costs and usage inconveniences. At the same time, the lifting component 2 achieves stable height adjustment through the push rod 23. Combined with the stable installation of the bracket component 3, the overall solution is optimized from multiple dimensions such as rotation accuracy, structural reliability, and operational stability, providing users with a more reliable and convenient monitor support solution.

[0046] Please refer to the following: Figure 3 and Figure 4 In one embodiment, the rotating fixing component 11 is provided with a bearing seat 111, which is connected to the inner ring of the thrust bearing 13. The rotating component 12 is provided with a groove 120, in which the outer ring of the thrust bearing 13 is embedded.

[0047] Specifically, the bearing seat 111 on the rotating fixed component 11 is connected to the inner ring of the thrust bearing 13 to form a stable fixed base. The bearing seat 111 can be designed with a specific shape and size to fit the inner ring, ensuring that the two are tightly connected. The groove 120 of the rotating component 12 is for matching with the outer ring of the thrust bearing 13. The dimensional accuracy and shape fit of the groove 120 ensure that the outer ring can be smoothly inserted and stably fixed.

[0048] When the rotating component 12 is subjected to force, the balls of the thrust bearing 13 roll between the raceways of the inner and outer rings. Since the inner ring is connected and fixed to the bearing housing 111, and the outer ring is embedded in the groove 120 of the rotating component 12, the rotating component 12 can rotate around the axis of the rotating fixed component 11. The rolling of the balls greatly reduces the frictional resistance, making the rotation smoother.

[0049] By adopting the above technical solution, this structural design makes the rotary connection more stable. Compared with some conventional connection methods, it can effectively avoid loosening and offset during rotation, improve rotation accuracy, and control the angle deviation within a very small range. At the same time, the good load-bearing performance of the thrust bearing 13 enables it to withstand the axial load caused by the large weight of the monitor, etc., which enhances the overall reliability and durability of the bracket, reduces component damage caused by connection structure problems, reduces maintenance costs, and provides users with a more stable and reliable user experience.

[0050] In one embodiment, the center of gravity of the rotating component 12 is offset from the axis of the thrust bearing 13 when rotating about the rotating fixed component 11; the thrust bearing 13 is formed with opposing first support end 133 and second support end 134, the first support end 133 being located close to the center of gravity of the rotating component 12.

[0051] Specifically, in terms of structural composition, the center of gravity of the rotating component 12 is specially positioned so that it deviates from the axis of the thrust bearing 13 when rotating around the rotating fixed component 11. At the same time, the thrust bearing 13 has a first support end 133 and a second support end 134, and the center of gravity of the rotating component 12 is close to the first support end 133.

[0052] Specifically, the projections of the center of gravity of the first support end 133, the second support end 134, and the rotating component 12 are located on a straight line. This arrangement makes the force transmission more direct and stable. The force generated when the rotating component 12 rotates can be transmitted more smoothly through the center of gravity to the two support ends of the thrust bearing 13, which helps to maintain the mechanical balance of the entire system, reduce vibration, noise and other problems caused by poor force transmission, and improve the stability and reliability of the equipment.

[0053] When the rotating component 12 rotates around the axis, the center of gravity off the axis will generate an eccentric torque. The first support end 133 and the second support end 134 of the thrust bearing 13 work together to balance the eccentric torque by relying on the rolling friction between the balls and the raceway and the bearing's own load-bearing capacity, thus ensuring the stable rotation of the rotating component 12. The center of gravity is set close to the first support end 133, so that the first support end 133 bears more load. During rotation, the first support end 133 undertakes the main support and stabilization role, while the second support end 134 assists in maintaining the overall balance.

[0054] This design optimizes the force distribution of the thrust bearing 13. Compared with the method of setting the center of gravity along the axis, it can reduce excessive wear in some parts of the bearing and extend the service life of the thrust bearing 13. Due to the offset of the center of gravity, a more complex structure can be designed for the rotating component 12 in a limited space, such as adding counterweights or functional modules to improve the functional expandability of the bracket. In addition, the special center of gravity layout can also enable the rotating component 12 to produce specific motion characteristics when rotating, such as achieving more flexible angle fine adjustment, improving the adjustment accuracy of devices such as displays, and meeting the diverse usage needs of users.

[0055] Please refer to the following: Figure 5 In one embodiment, the rotating fixing component 11 includes a first gear 112 and a rotating shaft 113 coaxially connected to the first gear 112. The first gear 112 is provided with a groove 120. The rotating component 12 includes a rotating fixing plate 121 and a second gear 122 disposed on the rotating fixing plate 121. The rotating fixing plate 121 is provided with a bearing seat 111. The rotating fixing plate 121 is connected to the lifting fixing component 21. The rotating fixing plate 121 and the rotating shaft 113 are rotatably connected by a ball bearing. The thrust bearing 13 is disposed between the first gear 112 and the rotating fixing plate 121. The second gear 122 meshes with the first gear 112 and can rotate around its own axis to drive the rotating fixing plate 121 to rotate around the rotating shaft 113.

[0056] Specifically, the rotating fixing component 11 includes a first gear 112 and a rotating shaft 113. The first gear 112 has a groove 120, providing a structural foundation for the installation or mating of other components. The rotating component 12 includes a rotating fixing plate 121 and a second gear 122 disposed thereon. The rotating fixing plate 121 is provided with a bearing seat 111 and is connected to the lifting fixing component 21, forming a connection between the various components of the bracket. The rotating fixing plate 121 and the rotating shaft 113 are rotatably connected by ball bearings, while the thrust bearing 13 is disposed between the first gear 112 and the rotating fixing plate 121. The second gear 122 meshes with the first gear 112. These components together construct the transmission and support structure.

[0057] When the second gear 122 rotates around its own axis, based on the gear meshing principle, it drives the first gear 112 meshing with it to move, thereby causing the rotating shaft 113 coaxial with the first gear 112 to move. At the same time, the rotating fixed plate 121, being connected to the second gear 122, rotates around the rotating shaft 113 under the drive of the second gear 122, using ball bearings as the rotation medium. During this process, the thrust bearing 13 bears the axial load, ensuring the axial stability of the rotating fixed plate 121 when it rotates, while the ball bearings reduce the radial friction between the rotating fixed plate 121 and the rotating shaft 113, facilitating smooth rotation.

[0058] By adopting the above technical solution, gear meshing transmission has higher transmission accuracy and stability compared with traditional belt transmission, and can avoid the problem of rotation angle deviation caused by belt loosening and slippage. The combination of ball bearing and thrust bearing 13 bears radial and axial loads respectively, improving the overall load-bearing capacity and durability of rotating component 1, especially when the monitor rotates frequently, significantly reducing the risk of component damage. In addition, this structural design makes the connection between rotating component 12 and lifting and fixing component 21 more stable, ensuring the stability of the monitor during adjustment, while also providing the monitor with flexible rotation adjustment function to meet the diverse viewing needs of users and improve the user experience.

[0059] Please refer to the following: Figure 6 In one embodiment, the thrust bearing 13 includes a first thrust bearing cover plate 135, a second thrust bearing cover plate 136, and a thrust bearing rolling assembly 137 located between the first thrust bearing cover plate 135 and the second thrust bearing cover plate 136. The two ends of the thrust bearing rolling assembly 137 are slidably abutting against the first thrust bearing cover plate 135 and the second thrust bearing cover plate 136, respectively. The first thrust bearing cover plate 135 is connected to the first gear 112, and the second thrust bearing cover plate 136 is connected to the rotating fixed plate 121. The thrust bearing rolling assembly 137 includes an outer cage 1371, an inner cage 1372, and a cylinder 1373 located between the outer cage 1371 and the inner cage 1372. The cylinder 1373 is slidably abutting against the first thrust bearing cover plate 135 and the second thrust bearing cover plate 136, respectively. The outer cage 1371 is embedded in the groove 120, and the inner cage 1372 is connected to the bearing seat 111.

[0060] Specifically, the thrust bearing 13 adopts a layered assembly structure, consisting of a first thrust bearing cover plate 135, a second thrust bearing cover plate 136, and a thrust bearing rolling assembly 137 located between them, forming the core architecture. The first thrust bearing cover plate 135 is connected to the first gear 112, and the second thrust bearing cover plate 136 is fixed to the rotating fixed plate 121, forming fixed supports at both ends. The thrust bearing rolling assembly 137 is further refined, including an outer cage 1371, an inner cage 1372, and a cylinder 1373. The outer cage 1371 is embedded in the groove 120 of the first gear 112 to achieve circumferential positioning. The inner cage 1372 is connected to the bearing seat 111 on the rotating fixed plate 121, and the cylinder 1373 is evenly distributed between the outer and inner cages 1372, with its two ends slidingly abutting against the first and second thrust bearing cover plates 136, respectively, forming a complete rolling friction pair.

[0061] When the rotating component 12 is driven by an external force, the second gear 122 drives the rotating fixed plate 121 to rotate around the rotating shaft 113, and the second thrust bearing cover plate 136 moves accordingly. The cylinder 1373 rolls between the first thrust bearing cover plate 135 and the second thrust bearing cover plate 136, converting sliding friction into rolling friction and greatly reducing rotational resistance. The cooperation between the outer cage 1371 and the groove 120, and the inner cage 1372 and the bearing seat 111, ensures the stability of the thrust bearing rolling assembly 137 during rotation, while also sharing the axial load generated by the weight of the display, so that the force is transmitted through the path of the thrust bearing 13 cover plate, cylinder 1373, cage, and connecting component. Compared to the traditional integrated thrust bearing 13, the layered modular structure facilitates installation and maintenance, and allows for the individual replacement of worn parts; the introduction of the cylindrical rolling assembly 1373 reduces the coefficient of friction and extends the rotational life; the dual positioning mechanism of the outer cage 1371 and the inner cage 1372 improves rotational accuracy; in addition, the axial load is evenly distributed across the entire cross section of the thrust bearing 13, avoiding local stress concentration.

[0062] Please refer to it again. Figure 4 In one embodiment, the rotating fixing component 11 further includes a limiting piece 114 connected to the rotating shaft 113, and the rotating component 12 further includes a limiting fitting member disposed on the rotating fixing plate 121. The limiting fitting member 123 can rotate with the rotating fixing plate 121, and the limiting piece 114 is used to abut against the limiting fitting member 123 to limit the rotating fixing plate 121.

[0063] Specifically, the rotating fixing component 11 is equipped with a limiting piece 114 that is connected to the rotating shaft 113. Its position and shape are specially designed to provide a solid blocking structure to limit the rotation range of the rotating component 12. The rotating component 12 is provided with a limiting fitting 123 on the rotating fixing plate 121. The fitting is firmly connected to the rotating fixing plate 121 and can rotate synchronously with the rotating fixing plate 121.

[0064] When the rotating component 12 is driven by an external force to rotate the rotating fixed plate 121 around the rotating shaft 113 through gear meshing and other transmission methods, the limiting fitting component 123 also rotates accordingly. When it rotates to a certain angle, the limiting fitting component 123 will contact and abut with the fixed limiting piece 114. By using the mechanical block between the two, the rotating fixed plate 121 is restricted from continuing to rotate, thereby limiting the rotation angle of the rotating component 12 within the set range and avoiding structural damage or functional failure caused by excessive rotation.

[0065] By adopting the above technical solution, this limiting structure design effectively improves the safety and reliability of the stand, preventing problems such as cable pulling, stand deformation, or even monitor falling due to exceeding the reasonable angle range during monitor rotation adjustment. At the same time, the clearly defined rotation limit range also makes it easier for users to accurately adjust the monitor viewing angle, improving ease of use. In addition, the limiting structure is simple and practical, requiring no complex electronic control system, reducing production costs and maintenance difficulty. Furthermore, by reasonably setting the position and shape of the limiting piece 114 and the limiting mating part 123, the rotation angle range can be flexibly adjusted according to different usage scenarios and needs, enhancing the applicability of the stand.

[0066] Please refer to the following: Figure 7 In one embodiment, the lifting and fixing component 21 includes a base 211, and the lifting component 22 includes a connecting rod 221 and a sliding rod 222. The base 211 is provided with a sliding groove 2111, the connecting rod 221 is rotatably connected to the base 211, one end of the sliding rod 222 is slidably connected to the sliding groove 2111, and the other end of the sliding rod 222 is rotatably connected to the connecting rod 221. The end of the connecting rod 221 facing away from the base 211 is provided with a hanging bracket assembly 3. The two ends of the push rod 23 are rotatably connected to the base 211 and the connecting rod 221, respectively.

[0067] Specifically, the lifting structure includes a base 211, a connecting rod 221, a sliding rod 222, and a push rod 23. The base 211, as a basic component, is provided with a sliding groove 2111, which provides a track for the movement of the sliding rod 222. The connecting rod 221 is hinged to the base 211 by a rotatable connection, and can rotate around the connection point. The two ends of the sliding rod 222 are rotatably connected to the sliding groove 2111 and the connecting rod 221, respectively, forming a movable connection relationship. The bracket assembly 3 is installed at the end of the connecting rod 221 away from the base 211 and is used to support the display. The push rod 23 establishes a rotatable connection between the base 211 and the connecting rod 221, constituting the key link of the entire lifting drive.

[0068] The push rod 23 can extend and retract. When the push rod 23 extends, it applies a pushing force to the connecting rod 221. Since the connecting rod 221 is rotatably connected to the base 211, the connecting rod 221 rotates about the connection point under the action of the pushing force. At the same time, the sliding rod 222 slides in the sliding groove 2111 and rotates together with the connecting rod 221, thereby driving the hanging bracket assembly 3 and the display to move upward. Conversely, when the push rod 23 retracts, the pulling force causes the connecting rod 221 to rotate in the opposite direction, and the sliding rod 222 also slides accordingly, realizing the downward movement of the display.

[0069] By adopting the above technical solution, this lifting structure achieves stable and flexible lifting adjustment of the monitor through the linkage of multiple components. The sliding cooperation between the sliding groove 2111 and the sliding rod 222, as well as the rotational connection between the components, effectively reduces the jamming phenomenon during the lifting process and ensures smooth movement. Compared with the traditional single guide structure, this design can improve the load-bearing capacity and stability of the overall structure and reduce the risk of shaking by distributing the force of each component when supporting the monitor. In addition, its structure is simple and compact, which is convenient for manufacturing and maintenance. Moreover, the size and connection method of each component can be adjusted according to actual needs to adapt to monitors of different specifications and weights, and it has strong versatility and practicality.

[0070] In one embodiment, the lifting and fixing component 21 further includes a head connecting rod 212 and a thrust connecting rod 213. The two ends of the head connecting rod 212 are rotatably connected to the connecting rod 221 and the base 211, respectively, and the two ends of the thrust connecting rod 213 are rotatably connected to the head connecting rod 212 and the sliding rod 222, respectively.

[0071] Specifically, the lifting and fixing component 21 includes a newly added head connecting rod 212 and a thrust connecting rod 213. The two ends of the head connecting rod 212 are rotatably connected to the connecting rod 221 and the base 211, respectively. This connection method creates a movable triangular structural foundation, making the force transmission between the connecting rod 221 and the base 211 more stable and flexible. The two ends of the thrust connecting rod 213 are rotatably connected to the head connecting rod 212 and the sliding rod 222, respectively.

[0072] When the push rod 23 extends and retracts, driving the connecting rod 221 to rotate around the connection point with the base 211, the head connecting rod 212 moves along with the rotation of the connecting rod 221. Since it is also rotatably connected to the base 211, it can flexibly change its angle in space. At the same time, the push rod 213, whose two ends are rotatably connected to the head connecting rod 212 and the sliding rod 222 respectively, will push the sliding rod 222 to slide in the sliding groove 2111 of the base 211 under the drive of the movement of the head connecting rod 212. Or, when the sliding rod 222 is pushed, the push rod 213 will cause the head connecting rod 212 and the connecting rod 221 to move. The components work together to achieve smooth lifting and lowering of the monitor stand.

[0073] By adopting the above technical solution, this structural design significantly improves the stability of the lifting process. The multi-link structure formed by the head link 212 and the thrust link 213, compared with a simple direct connection, can better distribute the force during the lifting process, reduce the situation of excessive force at a single point, effectively avoid damage to components due to uneven force, and extend the service life of the bracket. Moreover, when adjusting the height of the monitor, the multi-link structure makes the lifting action smoother and reduces the phenomenon of jamming. Users can adjust the monitor to the required height more accurately, improving the user experience. In addition, this structure also increases the mechanical strength of the entire bracket, enabling it to support heavier monitors, broadening the applicability of the bracket, and allowing it to work stably in a variety of application scenarios.

[0074] In one embodiment, the lifting and fixing component 21 further includes a cover 214 covering the base 211 and an adapter 215 disposed between the cover 214 and the base 211, the adapter 215 being used for electrical connection with the display.

[0075] Specifically, the protective cover 214 is a shell-like structure that covers the outside of the base 211, providing protection for the internal structural components of the base 211, such as the sliding groove 2111 and the connecting rod 221. Its material may be engineering plastic or metal, and it has a certain strength and wear resistance. The adapter 215 is located in the gap between the protective cover 214 and the base 211. It is usually in the form of a circuit board or integrated module, and it is equipped with various electrical connection interfaces.

[0076] After the monitor is mounted on the bracket via the mounting bracket assembly 3, the monitor's power cord, data cable, and other cables can be connected to the corresponding interface on the adapter 215 through the cable threading holes reserved in the cover 214. The adapter 215 then transmits electrical signals or power to an external power source or other devices to realize the monitor's power supply and data interaction functions. At the same time, the cover 214 tightly covers the base 211, which can prevent dust and debris from entering the interior of the base 211 and avoid interference from foreign objects affecting the normal sliding and lifting of components such as the sliding rod 222.

[0077] By adopting the above technical solutions, the protective cover 214 effectively improves the protective performance of the stand, reduces component damage caused by external environmental factors, and extends the service life of the stand. The addition of the adapter 215 realizes the integration and concealment of the monitor's electrical connection, making cable management more organized, avoiding the risk of tangling or pulling caused by exposed cables, and improving desktop tidiness and safety. In addition, this design also makes it easier for users to quickly complete the installation and wiring of the monitor, enhancing the convenience of using the stand. Furthermore, the adapter 215 can be replaced or upgraded according to different monitor interface requirements, improving the stand's versatility and adaptability.

[0078] Secondly, a display support device is provided, including a display and the aforementioned display stand, wherein the display is connected to the display stand.

[0079] By adopting the above technical solution, in addition to the advantages of the monitor bracket in the above embodiments, the monitor support device in this embodiment also has the advantage of high durability.

[0080] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
