DETAILED DESCRIPTION

[0040] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0041] As Figures 1 to 19The utility model discloses an embodiment provides a kind of support for display device. Support for display device includes: pedestal frame 10;Supporting component 20, it is liftable relative to pedestal frame 10, supporting component 20 is used to support display device;Balancing component, including main elastic mechanism 30, rotating mechanism 40 and adjusting mechanism 50, rotating mechanism 40 is rotatably arranged in pedestal frame 10, rotating mechanism 40 is rotatably connected in supporting component 20, the first end of main elastic mechanism 30 is connected with pedestal frame 10, the second end of main elastic mechanism 30 acts on rotating mechanism 40, main elastic mechanism 30 is used to provide balancing force to rotating mechanism 40, so that supporting component 20 can keep balanced state in any position, adjusting mechanism 50 is used to make the second end of main elastic mechanism 30 move on rotating mechanism 40, to adapt to display device of different weight.

[0042] In the above technical solution, after the display device is installed on the supporting component 20, the gravity of the display device acts on the rotating mechanism 40 through the supporting component 20, the elastic force of the main elastic mechanism 30 acts on the rotating mechanism 40, and the torque generated by the gravity and the elastic force on the rotating mechanism 40 is equal, so that the rotating mechanism 40 can be kept at any position relative to the pedestal frame 10, so that the supporting component 20 can be kept at any position relative to the pedestal frame 10, thereby realizing the hovering of the display device. Therefore, when it is necessary to adjust the position of the display device in the vertical direction, the user can move the supporting component 20 to move the display device through the supporting component 20, so as to adjust the position of the display device. After the user removes the external force on the supporting component 20, the hovering of the display device can be realized again. Therefore, by using the main elastic mechanism 30 to provide a balancing force for the supporting component 20 supporting the display device, i.e., by using a mechanical balancing system, the problem of overheating protection in an electric system can be avoided, and the situation of shutdown and waiting for cooling during frequent lifting operations can be avoided, thereby meeting the demand for frequent lifting.

[0043] Further, compared with the problem of tedious operation caused by traditional manual lifting in the prior art, the display device support of the embodiment can realize the lifting of the display device by directly moving the supporting component 20, thereby reducing the complexity of operation and improving user experience. Compared with the problem of slow lifting speed caused by electric lifting in the prior art, the display device support of the embodiment can realize the rapid and smooth lifting of the display device by directly moving the supporting component 20 by the user, thereby avoiding the speed limitation of the electric lifting system.

[0044] Further, by the setting of the adjusting mechanism 50, the action point of the second end of the main elastic mechanism 30 on the rotating mechanism 40 can be fine-tuned, thereby adapting to display devices of different weights. Therefore, it can be ensured that the support for display device can provide stable support and high freedom of stopping function when facing various display devices.

[0045] Furthermore, this embodiment employs a mechanical balancing system based on the main elastic mechanism 30 and the rotating mechanism 40. This reduces the number of electronic components and motors, thereby lowering production costs and simplifying maintenance procedures to reduce long-term operating costs.

[0046] It should be noted that, in the embodiments of this utility model, the ability of the support component 20 to maintain a balanced state at any position means that the display device on the support component 20 can be freely suspended at any position within the lifting range of the support component 20.

[0047] Example 1

[0048] like Figures 1 to 11 As shown in the first embodiment of this utility model, the support for the display device further includes a guide member 21, which is installed inside the base frame 10; the support assembly 20 includes a sliding member 22, which is slidably engaged with the guide member 21; the rotating mechanism 40 is used to support the sliding member 22; and part of the sliding member 22 extends out of the base frame 10 and is used to support the display device.

[0049] With the above configuration, the display device is supported on the slider 22, which partially extends out of the base frame 10. The guide 21 is fixed inside the base frame 10, providing a sliding track for the slider 22. When the height of the display device needs to be adjusted, the operator can manually apply force to the slider 22. Due to the sliding engagement between the slider 22 and the guide 21, the applied force causes the slider 22 to slide along the guide 21, thereby raising or lowering the display device. During the raising and lowering of the slider 22, the main elastic mechanism 30 supports the slider 22 through the rotating mechanism 40, ensuring smooth movement of the slider 22 and balancing the weight of the display device, allowing for free height adjustment. Thus, the sliding engagement between the slider 22 and the guide 21, along with the supporting and balancing capabilities of the main elastic mechanism 30 and the rotating mechanism 40, enables the bracket to be raised and lowered frequently, meeting the needs of users of different heights.

[0050] like Figure 5 , Figure 9 , Figure 10 As shown in Embodiment 1 of this utility model, the guide member 21 is a guide rod, and the sliding member 22 is a sleeve. The first end of the sleeve is slidably engaged with the guide rod, and the second end of the sleeve extends out of the base frame 10 and is used to support the display device. In this way, a sliding engagement between the guide member 21 and the sliding member 22 can be achieved.

[0051] like Figure 10As shown in Embodiment 1 of this utility model, the support for the display device further includes a first mounting sleeve 24 and a first sliding sleeve 25. The first mounting sleeve 24 is connected to the first end of the sleeve, and the first sliding sleeve 25 is installed between the first mounting sleeve 24 and the guide rod. This allows the sleeve and the guide rod to slide more smoothly.

[0052] Preferably, in Embodiment 1 of this utility model, the first sliding sleeve 25 is a linear bearing.

[0053] like Figure 5 and Figure 10 As shown, in Embodiment 1 of this utility model, the sleeve includes a main cylinder section 221 and an extension cylinder section 222. The main cylinder section 221 is located inside the base frame 10 and is slidably engaged with the guide rod. At least part of the extension cylinder section 222 extends out of the base frame 10. The bracket for the display device also includes a second mounting sleeve 26 and a second sliding sleeve 27. The two ends of the second mounting sleeve 26 are respectively connected to the main cylinder section 221 and the extension cylinder section 222. The second sliding sleeve 27 is installed between the second mounting sleeve 26 and the guide rod.

[0054] With the above configuration, the sleeve can be extended so that it can extend out of the base frame 10 to support the display device, and the second sliding sleeve 27 can further make the sliding between the sleeve and the guide rod smoother.

[0055] Preferably, in Embodiment 1 of this utility model, the second sliding sleeve 27 is a linear bearing.

[0056] Preferably, such as Figure 10 As shown in Embodiment 1 of this utility model, two linear bearings are respectively mounted on the first mounting sleeve 24 and the second mounting sleeve 26, and each linear bearing is blocked at both ends by inner retaining rings 28. One end of the first mounting sleeve 24 is threaded and can be threaded to engage with the main cylinder section 221, so that the bearing is mounted on one end of the main cylinder section 221. Both ends of the second mounting sleeve 26 are threaded. One end of the second mounting sleeve 26 is connected to the main cylinder section 221, and the other end of the second mounting sleeve 26 is connected to the extension cylinder section 222.

[0057] like Figure 4 As shown in Embodiment 1 of this utility model, the support for the display device further includes a hanging arm assembly 80 and a limiting member 81. The hanging arm assembly 80 is installed on the sleeve and is located outside the base frame 10. The limiting member 81 is detachably installed on the sleeve and is located between the base frame 10 and the hanging arm assembly 80. The limiting member 81 is used to restrict the movement of the sleeve.

[0058] With the above configuration, when the display device is installed on the mounting arm assembly 80, the limiting member 81 can be installed on the sleeve. In this way, even if the elastic force provided by the main elastic mechanism 30 to the rotating mechanism 40 is insufficient to support the support assembly 20, the support assembly 20 will not drop due to the weight of the display device under the action of the limiting member 81. This facilitates the installation of the display device and also makes it easy to adjust the position of the second end of the main elastic mechanism 30 on the rotating mechanism 40 using the adjusting mechanism 50 to adapt to the weight of the current display device. When the display device can be in a balanced state, the limiting member 81 can be removed from the sleeve to adjust the height of the display device.

[0059] Preferably, in Embodiment 1 of this utility model, a through hole can be provided on the sleeve, and the limiting member 81 is a wrench that passes through the through hole.

[0060] Preferably, such as Figure 3 As shown in Embodiment 1 of this utility model, the hanging arm assembly 80 includes a crossbar connecting plate 83, a crossbar 84, and a hanging arm 85. After the display device is installed, the hanging arm 85 is hung on the crossbar 84. The crossbar connecting plate 83 is installed on the extension tube section 222 and is connected to the crossbar 84. In this way, the crossbar 84 is connected to the extension tube section 222. This installation method can reduce the packaging volume.

[0061] like Figure 10 As shown in Embodiment 1 of this utility model, the support for the display device further includes a limiting member 82; the guide member 21 is provided with a limiting member 82 to limit the sliding range of the sliding member 22.

[0062] In the above technical solution, by setting the limiting component 82, it can be ensured that the display device will not exceed the safe range when adjusting the height, so as to prevent structural damage or the risk of the display device falling due to excessive lifting or lowering.

[0063] Preferably, in Embodiment 1 of this utility model, the guide member 21 is fixedly installed on the base frame 10.

[0064] like Figure 5 As shown, in the first embodiment of this utility model, there are two guide members 21 and two sliding members 22. The two sliding members 22 are slidably engaged with the two guide members 21 respectively. The support assembly also includes a connector 23, which is located inside the base frame 10. The two sliding members 22 are connected to the two ends of the connector 23, and the rotating mechanism 40 is rotatably connected to the connector 23.

[0065] In the technical solution, the configuration of the two guide members 21 and the two sliding members 22 significantly enhances the stability of the overall structure compared to the design of a single guide member and a single sliding member. This double-sided support structural design makes the display device more stable during lifting, reducing the risk of shaking and tilting, especially when carrying heavy loads. Moreover, the two sliding members 22 are connected by the connecting member 23, which not only disperses the weight of the display device, improving the load-bearing capacity, but also ensures that the bracket maintains good structural stability and smooth movement even when carrying heavy display devices.

[0066] Preferably, in the first embodiment of the utility model, the connecting member 23 is connected with the main cylinder segment 221. The connecting member 23 is a connecting plate.

[0067] Preferably, as shown in the first embodiment of the utility model, the top of the connecting member 23 is provided with a limiting pad 91. When the connecting member 23 rises to the highest position, the limiting pad 91 contacts the upper cover plate 14. Figure 8

[0068] As shown in the first embodiment of the utility model, the adjusting mechanism 50 includes an operating member 51, a moving member 52, and an adjusting member 53. The moving member 52 is located between the two ends of the adjusting member 53, and the second end of the main elastic mechanism 30 is connected with the moving member 52. By operating the operating member 51, the moving member 52 moves on the adjusting member 53. Figure 6 Figure 8 As shown in the first embodiment of the utility model, the adjusting member 53 is rotatably arranged on the rotating mechanism 40, and the moving member 52 is located on the outer periphery of the adjusting member 53 and threadedly cooperates with the adjusting member 53. The moving member 52 is slidingly matched with the rotating mechanism 40, and the operating member 51 is used to drive the adjusting member 53 to rotate.

[0069] In the technical solution, by operating the operating member 51, the moving member 52 moves on the adjusting member 53, which can drive the second end of the main elastic mechanism 30 to move relative to the first end of the main elastic mechanism 30, so as to stretch the main elastic mechanism 30 or shorten the main elastic mechanism 30, thereby increasing or reducing the torque generated by the elastic force on the rotating mechanism 40, adjusting the pre-tightening force of the main elastic mechanism 30, and enabling the display device bracket to balance the installation of display devices with different weights.

[0070] As shown in the first embodiment of the utility model, the adjusting member 53 is rotatably arranged on the rotating mechanism 40, and the moving member 52 is located on the outer periphery of the adjusting member 53 and threadedly cooperates with the adjusting member 53. The moving member 52 is slidingly matched with the rotating mechanism 40, and the operating member 51 is used to drive the adjusting member 53 to rotate. Figure 8

[0071] ​​​In the technical scheme, the user only needs to rotate the adjusting member 53 through the operation member 51 to realize the movement of the moving member 52, so as to adjust the height of the display device, which is easy to use; and through the thread cooperation between the moving member 52 and the adjusting member 53, the small displacement change can be realized, so that the user can accurately adjust the height of the display device to adapt to different use scenarios and user needs.

[0072] Further, the moving member 52 is in sliding cooperation with the rotating mechanism 40, so as to ensure the smoothness and low friction during the adjustment, so that the display device experiences more smoothness during the lifting and lowering and does not appear to be stuck or resistant.

[0073] Preferably, in the embodiment one of the utility model, the adjusting member 53 is a screw rod.

[0075] In the technical scheme, the axis of the operation piece 511 and the axis of the adjusting member 53 are arranged at an angle, and the first gear 512 and the second gear 513 are meshed, so that the rotating force of the operation piece 511 can be transmitted to the adjusting member 53 through the first gear 512 and the second gear 513, the operation member 51 can be installed in a limited space, the space utilization of the overall structure is optimized, and the interference between the operation piece 511 and other structures is avoided, so that the operation is smooth.

[0076] Further, at least one end of the operation piece 511 is exposed to the rotating mechanism 40 and the base frame 10, so that the operator can directly operate the operation piece 511 without disassembling or moving other components, and the convenience and efficiency of operation are improved.

[0077] Preferably, in the embodiment one of the utility model, one end of the operation piece 511 is exposed to the rotating mechanism 40 and the base frame 10, which means that one end of the operation piece 511 can be in the rotating mechanism 40, the rotating mechanism 40 and the base frame 10 are both provided with through holes, and the two through holes are both arranged corresponding to one end of the operation piece 511, so that a wrench can be inserted into the two through holes to adjust the operation piece 511; one end of the operation piece 511 can also extend out of the rotating mechanism 40 and the base frame 10 for easy adjustment.

[0078] Preferably, in the embodiment one of the utility model, first gear 512 and second gear 513 are umbrella tooth.

[0097] In the above technical scheme, the connection of side plate 13, upper cover plate 14 and lower cover plate 15 forms a firm support frame, which provides a stable structural basis for the entire display equipment support, enhances the bearing capacity and mechanical strength, and ensures the stability and safety when supporting heavy objects;The arrangement of front cover plate 16 and rear cover plate 17 encloses the balancing assembly and other internal mechanical structures in a mounting cavity, effectively protects these components from external environmental factors (such as dust, water vapor), and also hides the internal complex mechanical structure, improves the neatness and beauty of the equipment.

[0098] Specifically, as shown in Figure 5 The upper cover plate 14 can be installed with an embedded power supply 86 and internal wiring, so that the power supply line of the display device can be hidden, making it more concise.

[0099] As shown in Figure 3 In the first embodiment of the utility model, the support for display device further includes support legs 60, the base frame 10 is arranged on the support legs 60, and the side, away from the base frame 10, of the support legs 60 is provided with a plurality of rolling members.

[0100] In the above technical solution, the rolling members can enhance the mobility of the support, and the user can easily move the display device between different positions without additional moving tools or manpower.

[0101] It should be noted that the first embodiment of the utility model provides a support for display device, which has the advantages of high freedom of stopping, frequent lifting at will, large load bearing range, good lifting experience and convenient force value adjustment.

[0102] Preferably, in the first embodiment of the utility model, the support legs 60 are two, and the two support legs 60 are left and right support legs respectively.

[0103] As shown in Figure 6 In the first embodiment of the utility model, the support for display device further includes an adjusting screw 92 rotatably arranged on the base frame 10, a spring sleeve 96 is arranged on the elastic member 31, and the adjusting screw 92 is threadedly matched with the spring sleeve 96, that is, rotating the adjusting screw 92 can stretch the elastic member 31 (the elastic member 31 can be a mechanical spring or an air spring, if it is an air spring, the adjusting screw 92 does not need to be configured, and one end of the air spring is directly mounted on the base frame 10). In the first embodiment, the elastic member 31 is a mechanical spring, one end of the rope 33 is connected to the elastic member 31, and the other end of the rope 33 is hingedly connected to the two rotating plates in the rotating member 42 through the guide member 32. In this way, rotating the adjusting screw 92 can stretch the elastic member 31, and only the initial stretching amount needs to be set, and subsequent changes in load do not need to rotate the adjusting screw 92 to adjust the spring force.

[0104] It should be noted that in the first embodiment of the utility model, when an external force is applied to the extension cylinder segment 222, the extension cylinder segment 222 is lifted, driving the connecting member 23 to lift, so that the rotating mechanism 40 is rotated, and then the elastic member 31 is stretched through the rope 33, generating a spring force to balance the external force applied externally.

[0105] The support of the display device of the embodiment satisfies the free stop of a certain load range, and the process of adjusting the load is as follows: the first gear 512 can be rotated to drive the adjusting member 53 to rotate, so that the moving member 52 moves, and one end of the rope 33 is connected to the moving member 52, so that the elastic member 31 can be stretched on the one hand to change the initial stretching force of the elastic member 31, and on the other hand, the action point of the elastic member 31 on the rotating mechanism 40 can be changed, so as to adapt to display devices of different weights. The rear cover plate 17 is provided with a through hole for adjusting the first gear 512 and a slot for viewing the indicating strip, and the slot is marked with a scale. Since the rotating plate is at different angles at different heights, the through hole of the first gear 512 and the slot of the indicating strip on the rear cover plate 17 can correspond at the highest position, so a limit (i.e. a limiting member 81) is needed at the highest position. In the first embodiment of the present application, a through hole is formed in the extended barrel section 222 of the sliding member 22, the limiting member 81 (wrench or screwdriver) is inserted through the through hole and abuts against the upper surface of the guide member 21, so that the sliding member 22 cannot be lifted. At this time, the force value is adjusted, the indicating strip is adjusted to the same scale as the weight of the display device, and finally, the limiting of the wrench or screwdriver is removed, and then the spring force can be relied on to balance the gravity of the display device.

[0106] It should be noted that in the first embodiment of the present application, the balance of the elastic member 31 and the gravity of the display device is achieved, and the gravity acts on the rotating member 42 through the connecting member 23 and the supporting member 41. Since the gravity is constant, but the angle between the supporting member 41 and the rotating member 42 is changing, that is, the torque of the rotating member 42 caused by the gravity is always changing.

[0107] It should be noted that in the first embodiment of the present application, the elastic force acts on the rotating member 42 through the rope 33, the elastic force of the elastic member 31 is always changing, the angle between the elastic force and the rotating member 42 is also always changing, that is, the torque of the rotating member caused by the elastic force is also always changing. In order to enable the display device to be freely stopped, it is necessary to ensure that the torque of the gravity is always equal to the torque of the elastic force at each position. By listing the formulas and inputting the computer simulation, the parameters of the elastic member 31 and the elastic element 72, and the important parameters such as the position of the connecting point of the elastic force and the gravity on the rotating member 42 can be obtained.

[0108] Embodiment two

[0109] As shown in Figures 12 to 19 the difference between the second embodiment of the present application and the first embodiment is that the guide member 21 comprises two spaced apart sliding rails, and the sliding member 22 is a sliding plate. In this way, the sliding cooperation between the guide member 21 and the sliding member 22 can be achieved.

[0110] As shown in Figure 17As shown in Embodiment 2 of this utility model, a limiting member 82 is provided inside the base frame 10. The limiting member 82 is located below the rotating mechanism 40 to limit the rotation range of the rotating mechanism 40.

[0111] In the above technical solution, by setting the limiting component 82 to limit the maximum angle of rotation of the rotating mechanism 40, it can be ensured that the display device will not exceed the safe range when adjusting the height, so as to prevent the risk of structural damage or the display device falling due to excessive lifting or lowering.

[0112] Preferably, such as Figure 14 As shown in Embodiment 2 of this utility model, there is one guide member 21 and one sliding member 22, and the rotating mechanism 40 is rotatably engaged with the sliding member 22. By simplifying the guide member 21 and the sliding member 22 into a single component, the number of parts is reduced, thereby simplifying the overall structure and reducing the complexity of assembly and maintenance; moreover, the single guide member 21 and sliding member 22 can also reduce mechanical failure points and improve the reliability and durability of the system.

At least a portion of the operating element 511 is exposed outside the rotating mechanism 40 and the base frame 10. By exposing the operating element 511 to the rotating mechanism 40 and the base frame 10, the operating element 511 can be rotated using a wrench, thereby driving the adjusting component 53 to rotate.

[0114] It should be noted that, in Embodiment 2 of this utility model, at least some of the operating components 511 are exposed outside the rotating mechanism 40 and the base frame 10, meaning that at least some of the operating components 511 can be inside the rotating mechanism 40. Both the rotating mechanism 40 and the base frame 10 are provided with through holes, and both through holes are corresponding to at least some of the operating components 511. In this way, a wrench can be inserted into the two through holes to adjust the operating components 511. At least some of the operating components 511 can also extend out of the rotating mechanism 40 and the base frame 10 for easy adjustment.

[0115] like Figure 14 As shown in Embodiment 2 of this utility model, there is only one balancing component. This reduces the number of parts, thereby simplifying the overall structure and reducing the complexity of assembly and maintenance.

[0116] like Figure 14 As shown, in the second embodiment of this utility model, a connecting plate 97 is provided on the base frame 10. The adjusting screw 92 passes through the connecting plate 97 and is threadedly engaged with the spring sleeve 96 on the elastic member 31. Rotating the adjusting screw 92 can stretch the elastic member 31 to change the preset initial spring force (stretching the elastic member 31 here is not for adjusting to adapt to different load-bearing televisions, this is just the initial preset spring force).

[0117] As shown in Figure 19 one embodiment, spring cover 96 and connecting plate 97 can be cancelled, and connecting shaft 99 is used instead, and connecting shaft 99 is installed on base frame 10. Elastic member 31 is provided with hook 98, and when installed, hook 98 of elastic member 31 is stretched to hang on connecting shaft 99 by using a tool, so that spring cover 96 and screw rod can be reduced, and cost can be reduced.

[0118] As shown in Figure 14 embodiment two of the utility model, the chain wheel is installed on the base frame 10 through the chain wheel frame 95, and the chain wheel can move in a circle.

[0119] As shown in Figure 16 embodiment two of the utility model, rotating mechanism 40 further includes third connecting shaft 59, one end of the two rotating plates is hinged with supporting member 41 through third connecting shaft 59, the other end of the two rotating plates is hinged with base frame 10 through first connecting shaft 56, second connecting shaft 57 is installed between the two rotating plates, first connecting shaft 56, second connecting shaft 57 and third connecting shaft 59 are used for connecting the two rotating plates, adjusting member 53 is rotatably arranged in first connecting shaft 56 and second connecting shaft 57, the tail end of adjusting member 53 is limited by a nut, the head end of adjusting member 53 is provided with operating member 51, operating member 51 is provided with an internal hexagonal hole, both ends of moving member 52 are provided with limiting shaft 521, two limiting shafts and two sliding grooves are in sliding fit, base frame 10 is provided with a hole, an internal hexagonal wrench can rotate adjusting member 53 through the hole, the position of chain rope on rotating mechanism 40 is changed, so that different weight televisions can be adapted.

[0120] As shown in Figure 13 embodiment two of the utility model, the display equipment support further includes base 93 and panel decoration strip 94, and base frame 10 is arranged on base 93, wherein the front cover plate 16 of base frame 10 includes upper half cover plate 161 and lower half cover plate 162, so as to cover the internal structure of base frame 10. Hanging arm 85 is hung on horizontal rod connecting plate 83 after installing the television, horizontal rod connecting plate 83 is fixed on sliding member 22, and panel decoration strip is used for covering the screw for fixing horizontal rod connecting plate 83.

[0121] In one embodiment, auxiliary elastic mechanism 70 can also not be arranged.

[0122] It should be noted that embodiment two of the utility model provides a display equipment support with high free lifting, large bearing range, good lifting experience and convenient force value adjustment.

[0123] It should be noted that the display device support of the second embodiment of the present application can also satisfy different weight televisions. For example, when the weight of the television is small, the adjusting member 53 is rotated to make the moving member 52 close to the first connecting shaft 56, and the elastic force acts on the rotating mechanism 40 through the chain rope, so that the torque of the rotating mechanism 40 is reduced, thereby adapting to the weight of the small weight television. When the weight of the television is large, the adjusting member 53 is rotated to make the moving member 52 away from the first connecting shaft 56, and the elastic force acts on the rotating mechanism 40 through the chain rope, so that the torque of the rotating mechanism 40 is increased, thereby adapting to the weight of the large weight television.

[0124] It should be noted that the display device support of the second embodiment of the present application can also not be provided with the auxiliary elastic mechanism 70.

[0125] The other structures of the second embodiment of the present application are the same as those of the first embodiment, and will not be described here.

[0126] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects: after the display device is installed on the support assembly, the gravity of the display device acts on the rotating mechanism through the support assembly, the elastic force of the main elastic mechanism acts on the rotating mechanism, and the torque generated by the gravity and the elastic force on the rotating mechanism is equal, so that the rotating mechanism can be kept at any position relative to the base frame, so that the support assembly can be kept at any position relative to the base frame, thereby realizing the hovering of the display device. When it is necessary to adjust the position of the display device in the vertical direction, the user can move the support assembly to move the display device through the support assembly, so as to adjust the position of the display device. After the user removes the external force on the support assembly, the hovering of the display device can be realized again. In this way, the main elastic mechanism is used to provide a balance force for the support assembly for supporting the display device, that is, a mechanical balance system is used to avoid the overheat protection problem commonly found in electric systems, and the machine will not stop and wait for cooling in frequent lifting operations, thereby meeting the frequent lifting requirements.

[0127] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications.
