Abstract
Description
Technical Field
[0001] This application relates to the field of display device technology, and in particular to a lifting bracket and a display device. Background Technology
[0002] Monitors typically require a monitor stand to support them on a flat surface, such as a desktop. Some monitor stands not only support the monitor but also have the function of adjusting the monitor's height, allowing users to adjust the monitor to the most comfortable viewing height and improve user comfort.
[0003] To achieve height adjustment, traditional monitor stands typically use a sliding rail assembly. This assembly consists of two parallel guide rails, each divided into a fixed section and a sliding section. The fixed section is securely connected to the monitor stand, while the sliding section is connected to the monitor. By moving the sliding section along the fixed section, the user can easily adjust the monitor's height.
[0004] However, during the process of the monitor rising or falling, the forces on the two guide rails may not be completely equal, which can cause displacement deviation in the movement of the monitor, resulting in uneven sliding. Utility Model Content

[0006] On the one hand, a lifting support is provided, including:
[0007] Main support, sliding part and rolling mechanism;
[0008] The main support has an accommodating space and a first opening communicating with the accommodating space. The inner wall of the accommodating space has a first guide groove, and the extending direction of the first guide groove is parallel to the extending direction of the main support.
[0009] The sliding part includes: a sliding part body and a connecting member connected to each other. The sliding part body is installed in the accommodating space. At least a portion of the connecting member extends out of the accommodating space through the first opening.

Parts of the balls are located in the corresponding openings, and the parts of the balls that protrude toward the main support are located in the first guide groove, and the parts of the balls that protrude toward the sliding part body are located in the second guide groove.
[0016] Optionally, the size of the opening is smaller than the diameter of the ball, and the maximum width of the portion of the ball protruding toward the main bracket is greater than the maximum width of the portion of the ball protruding toward the sliding part body.

[0025] The beneficial effects of the technical solutions provided in this application include at least the following:
[0026] Because the main support has a first guide groove, and the sliding part body in the sliding section has a second guide groove corresponding to and communicating with the first guide groove, and multiple balls in the rolling mechanism are simultaneously located in the first and second guide grooves, a fixed rolling path can be provided for the balls through the first and second guide grooves. This ensures that the sliding part strictly follows a predetermined trajectory when moving, and even if the sliding part is subjected to uneven force, it can self-adjust due to the rolling characteristics of the balls to maintain a stable movement trajectory, effectively avoiding displacement deviation of the sliding part during movement, thereby improving the smoothness of sliding. Furthermore, the multiple balls in the rolling mechanism can also reduce the friction between the main support and the sliding part body in the sliding section, extending the service life of the lifting support. In addition, by simultaneously setting multiple balls in the rolling mechanism in the first and second guide grooves, the double slide rail design in the prior art is eliminated. This not only simplifies the assembly process of the lifting support but also significantly saves assembly costs and manpower, improving production efficiency. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0038] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a lifting support provided in an embodiment of this application. Figure 2 yes Figure 1 The diagram shows a cross-sectional view of a lifting support. The lifting support 000 may include: a main support 100, a sliding part 200, and a rolling mechanism 300.
[0039] To see the structure of the lifting bracket 000 more clearly, please refer to... Figure 3 , Figure 3 This is an exploded view of a lifting support provided in an embodiment of this application. The main support 100 in the lifting support 000 may have a receiving space C and a first opening K1 communicating with the receiving space C. The inner wall of the receiving space C may have a first guide groove F1, and the extension direction of the first guide groove F1 may be parallel to the extension direction of the main support 100.
[0040] The sliding part 200 in the lifting bracket 000 may include a sliding part body 201 and a connecting member 202 connected to each other. The sliding part body 201 may be installed in the accommodating space C, and at least a portion of the connecting member 202 may extend out of the accommodating space C through a first opening K1. The sliding part body 201 may have a second guide groove F2 that communicates with the first guide groove F1.
[0041] The rolling mechanism 300 in the lifting bracket 000 can be located in the accommodating space C, and the rolling mechanism 300 can be distributed between the main bracket 100 and the sliding body 201. The rolling mechanism 300 can have multiple balls 301, a portion of which are located in the first guide groove F1 and another portion are located in the second guide groove F2.
[0042] In this embodiment, the main support 100 has a first guide groove F1, and the sliding part body 201 in the sliding part 200 has a second guide groove F2 corresponding to and communicating with the first guide groove F1. Furthermore, multiple balls 301 in the rolling mechanism 300 are simultaneously located within the first guide groove F1 and the second guide groove F2. Therefore, the first guide groove F1 and the second guide groove F2 provide a fixed rolling path for the balls 301, ensuring that the sliding part 200 strictly follows a predetermined trajectory during movement. Even when the sliding part 200 is subjected to uneven force, it can self-adjust due to the rolling characteristics of the balls 301 to maintain a stable movement trajectory, effectively preventing displacement deviation during movement and thus improving the smoothness of sliding. Moreover, the multiple balls 301 in the rolling mechanism 300 can reduce the friction between the main support 100 and the sliding part body 201 in the sliding part 200, extending the service life of the lifting support 000. Furthermore, by simultaneously setting multiple balls 301 in the rolling mechanism 300 within the first guide groove F1 and the second guide groove F2, the dual slide rail design in the prior art is eliminated. This not only simplifies the assembly process of the lifting bracket 000, but also significantly saves assembly costs and manpower, thereby improving production efficiency.
[0043] In summary, this application proposes a lifting bracket, comprising: a main bracket, a sliding part, and a rolling mechanism. The main bracket has a first guide groove, the sliding part body has a second guide groove corresponding to and communicating with the first guide groove, and multiple balls in the rolling mechanism are simultaneously located within the first and second guide grooves. Therefore, the first and second guide grooves provide a fixed rolling path for the balls, ensuring that the sliding part strictly follows a predetermined trajectory during movement. Even under uneven force, the sliding part can self-adjust due to the rolling characteristics of the balls to maintain a stable movement trajectory, effectively preventing displacement deviation during movement and improving the smoothness of sliding. Furthermore, the multiple balls in the rolling mechanism reduce the friction between the main bracket and the sliding part body, extending the service life of the lifting bracket. In addition, by simultaneously arranging multiple balls in the rolling mechanism within the first and second guide grooves, the dual-rail design of the prior art is eliminated. This not only simplifies the assembly process of the lifting bracket but also significantly saves assembly costs and manpower, improving production efficiency.
[0044] In the embodiments of this application, please refer to Figure 4 , Figure 4 yes Figure 1 A cross-sectional view of another lifting bracket is shown. The first guide groove F1 on the inner wall of the accommodating space C in the main bracket 100 and the second guide groove F2 on the sliding part body 201 can be used to form a rolling channel L, the extending direction of which can be parallel to the extending direction of the main bracket 100.
[0045] In this process, at least some of the balls 301 in the rolling mechanism 300 may be located within the rolling channel L.
[0046] In this configuration, with the rolling mechanism 300 distributed between the main support 100 and the sliding body 201, and the multiple balls 301 in the rolling mechanism 300 located within the rolling channel L formed by the first guide groove F1 and the second guide groove F2, the balls 301 can exert a restraining force on the sliding body 201, ensuring that the sliding body 201 can only move within the rolling channel L. This prevents the sliding body 201 from accidentally detaching from the first opening K1 connected to the accommodating space C during operation, thereby significantly improving the stability and safety of the overall structure of the lifting support 000.
[0047] Optional, such as Figure 4 As shown, the first guide groove F1 and the second guide groove F2 are both arc-shaped sliding grooves, and the balls 301 in the rolling mechanism 300 are in rolling contact with the first guide groove F1 and the second guide groove F2 respectively.
[0048] In this configuration, when the sliding body 201 rises relative to the main support 100, the upward driving force causes the sliding body 201 to begin moving. As the sliding body 201 moves, the ball bearing 301 makes rolling contact with the first guide groove F1 and the second guide groove F2. This rolling contact converts the upward driving force into the upward rolling motion of the ball bearing 301, causing the rolling mechanism 300 to rise synchronously with the sliding body 201. Conversely, when the sliding body 201 descends relative to the main support 100, the ball bearing 301 also makes a rolling descent between the first guide groove F1 and the second guide groove F2, thereby causing the rolling mechanism 300 to descend synchronously with the sliding body 201. Furthermore, since the rolling friction of the ball bearing 301 is much less than the sliding friction, this design can significantly reduce the wear of the lifting support components, thereby extending its service life.
[0049] In the embodiments of this application, please refer to Figure 4 and Figure 5 , Figure 5This is a schematic diagram of a rolling mechanism provided in an embodiment of this application. The rolling mechanism 300 in the lifting bracket 000 may include: a plurality of balls 301 and a sliding frame 302.
[0050] The sliding frame 302 in the rolling mechanism 300 is distributed between the main support 100 and the sliding part body 201, and the sliding frame 302 has multiple openings M corresponding to multiple balls 301. Parts of the balls 301 are located in the corresponding openings M, and the parts of the balls 301 that protrude toward the main support 100 are located in the first guide groove F1, and the parts of the balls 301 that protrude toward the sliding part body 201 are located in the second guide groove F2.
[0051] In this configuration, the ball bearing 301 is partially embedded in the opening M of the sliding frame 302. Simultaneously, the protruding portions of the ball bearing 301 are respectively embedded in the first guide groove F1 of the main support 100 and the second guide groove F2 of the sliding body 201. Thus, the sliding frame 302 can constrain the ball bearing 301 in the radial direction of the opening M, and the first guide groove F1 and the second guide groove F2 can effectively limit the movement of the ball bearing 301 along the axial direction of the opening M. This ensures the stability of the ball bearing 301 after installation and effectively prevents it from falling off even during rolling, thereby guaranteeing the overall reliability of the lifting support 000.
[0052] For example, the size of the opening M in the sliding frame 302 is smaller than the diameter of the ball 301. For instance, in the first direction X, the width of the opening M is smaller than the diameter of the ball 301, and / or, in the second direction Y, the width of the opening M is smaller than the diameter of the ball 301. Here, both the first direction X and the second direction Y can be parallel to the plane containing the opening M, and the first direction X can be perpendicular to the extension direction of the sliding frame 302, and the second direction Y can be parallel to the extension direction of the sliding frame 302.
[0053] Furthermore, in the third direction Z, the maximum width of the portion of the ball bearing 301 protruding toward the main support 100 is greater than the maximum width of the portion of the ball bearing 301 protruding toward the sliding body 201, wherein the third direction Z is perpendicular to the plane where the opening M is located.
[0054] It should be noted that the shape of the opening M can be various, such as: circle, ellipse, rectangle, square, etc. This application uses a square opening M as an example for illustration, and the size of the opening M here refers to the side length of the square.
[0055] Normally, when the sliding part body 201 moves up or down relative to the main support 100, the rolling mechanism 300 often experiences a change in the motion state of the balls 301 in the first guide groove F1 and the second guide groove F2 due to its own gravity, changing from simple rolling friction to a state of both rolling friction and sliding friction. This change causes relative displacement between the sliding part body 201 and the rolling mechanism 300, which in turn causes the balls 301 located at the outermost edge of the rolling mechanism 300 to lose contact with the second guide groove F2, ultimately posing a risk of the balls 301 falling off.
[0056] In this embodiment, since the maximum width of the portion of the ball bearing 301 protruding towards the main support 100 is greater than the maximum width of the portion of the ball bearing 301 protruding towards the sliding body 201, most of the ball bearing is sandwiched between the sliding frame 302 and the main support 100. Thus, the sliding frame 302 and the first guide groove F1 effectively limit the ball bearing 301 along the axial direction of the opening M. Therefore, even if the outermost ball bearing 301 of the rolling mechanism 300 loses contact with the second guide groove F2 due to gravity during the sliding process of the sliding part 200, the sliding frame 302 and the first guide groove F1 can still limit the ball bearing 301, preventing it from falling off.
[0057] In the embodiments of this application, such as Figure 5 As shown, the sliding frame 302 in the rolling mechanism 300 may include: a first plate 3021 and a second plate 3022 disposed opposite to each other, and a connecting plate 3023 for connecting the first plate 3021 and the second plate 3022; the connecting plate 3023 may be distributed on the side of the first plate 3021 and the second plate 3022 away from the first opening K1.
[0058] Among them, the multiple openings M in the sliding frame 302 are distributed on at least one of the first plate 3021, the second plate 3022 and the connecting plate 3023.
[0059] In this configuration, since the multiple openings M in the sliding frame 302 are distributed on at least one of the first plate 3021, the second plate 3022, and the connecting plate 3023, and these openings M correspond one-to-one with the multiple balls 301, the multiple balls 301 can be distributed on at least one plate. Due to their low coefficient of rolling friction, the balls 301 can significantly reduce resistance during sliding, thereby improving rolling efficiency. Furthermore, the balls can reduce wear caused by excessive localized force and reduce noise during rolling, thus effectively extending the service life of the rolling mechanism 300.
[0060] For example, please refer to Figure 4 , Figure 5 and Figure 6 , Figure 6 This is a schematic diagram of the structure of a main support provided in an embodiment of this application. A portion of the multiple openings M in the sliding frame 302 are distributed on the first plate 3021, and another portion of the openings M are distributed on the second plate 3022.
[0061] The inner wall of the accommodating space C in the main support 100 has a first guide groove F1 on the side facing the first plate 3021 and the side facing the second plate 3022.
[0062] In this configuration, since the multiple openings M on the sliding frame 302 are distributed on the first plate 3021 and the second plate 3022, and these openings M correspond one-to-one with the multiple balls 301, the balls 301 are also distributed on the two plates accordingly. Simultaneously, the inner wall of the accommodating space C of the main support 100 is provided with first guide grooves F1 on the side facing the first plate 3021 and the second plate 3022. This ensures that the sliding part body 201 can move smoothly along a predetermined path during movement, and that both sides of the sliding part body 201 are subjected to uniform guiding force. This greatly reduces the possibility of jamming or obstruction during movement, thereby improving the smoothness and stability of the sliding part 200's movement and enhancing the operating efficiency of the lifting support 000.
[0063] In the embodiments of this application, such as Figure 6 As shown, the inner wall of the accommodating space C in the main support 100 has at least two first guide grooves F1 arranged side by side on the side facing the first plate 3021.
[0064] And / or, the inner wall of the accommodating space C has at least two first guide grooves F1 arranged side by side on the side facing the second plate 3022.
[0065] For example, the inner wall of the accommodating space C in the main support 100 has two side-by-side first guide grooves F1 on the side facing the first plate 3021 and the side facing the second plate 3022.
[0066] Optional, please refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of a sliding part provided in an embodiment of this application. The sliding part body 201 of the sliding part 200 has two second guide grooves F2 that are connected to the two first guide grooves F1 on both the side facing the first plate 3021 and the side facing the second plate 3022.
[0067] In this configuration, the main support 100 has two parallel first guide grooves F1 on both sides facing the first plate 3021 and the second plate 3022, and the corresponding side of the sliding part body 201 is also equipped with a second guide groove F2 that precisely corresponds to these first guide grooves F1. This allows the multiple balls 301 in the rolling mechanism 300 to be distributed within multiple guide grooves, thus achieving multi-point guidance. Compared to having only one guide groove on each side, this multi-point guidance helps to distribute the force on the sliding part 200 during movement, making the force more even and extending the service life of the lifting support 000. Furthermore, due to the distribution of the balls 301 within multiple guide grooves, the sliding part 200 receives a more balanced guiding force during movement, thereby reducing the possibility of offset and swaying and improving the stability of the sliding part 200's movement.
[0068] Optional, please refer to Figure 8 , Figure 8 This is an exploded view of another lifting bracket provided in an embodiment of this application. In the extending direction of the main bracket 100, the length of the first guide groove F1 is greater than the length of the rolling mechanism 300, and the length of the rolling mechanism 300 is greater than the length of the sliding part body 201.
[0069] In this case, the sliding part 200 can have a larger range of travel during movement, so that the sliding part 200 can be easily raised and lowered within a larger range as needed, thus providing users with a more flexible and convenient adjustment space.
[0070] Optional, such as Figure 8 As shown, the lifting support 000 may further include a reinforcing support 400, which can be connected to the main support 100. Thus, through the secure connection between the reinforcing support 400 and the main support 100, the reinforcing support 400 can share the load borne by the main support 100, thereby effectively preventing structural deformation or damage to the main support 100 due to excessive load, and enhancing the overall structural stability of the lifting support 000.
[0071] In the embodiments of this application, such as Figure 8 As shown, the lifting bracket 000 may further include a constant force spring (not shown), which includes a coil spring and a spring seat. The main bracket 100 in the lifting bracket 000 also has a second opening K2 communicating with the accommodating space C. The spring seat is connected to the main bracket 100 at the second opening K2. One end of the coil spring is connected to the spring seat, and the other end is connected to the sliding part 200.
[0072] In this configuration, when the sliding part 200 rises or falls, it tends to fall naturally due to gravity. The coil spring connected to the sliding part 200 stretches or contracts accordingly as the sliding part 200 moves, generating a constant pulling force opposite to the weight of the sliding part 200. This constant pulling force balances the weight of the sliding part 200. When the sliding part 200 reaches a certain position, the pulling force generated by the coil spring is exactly equal to the weight of the sliding part 200, ensuring that the sliding part 200 can stably stop at any position during the lifting and lowering process.
[0073] In summary, this application proposes a lifting bracket, comprising: a main bracket, a sliding part, and a rolling mechanism. The main bracket has a first guide groove, the sliding part body has a second guide groove corresponding to and communicating with the first guide groove, and multiple balls in the rolling mechanism are simultaneously located within the first and second guide grooves. Therefore, the first and second guide grooves provide a fixed rolling path for the balls, ensuring that the sliding part strictly follows a predetermined trajectory during movement. Even under uneven force, the sliding part can self-adjust due to the rolling characteristics of the balls to maintain a stable movement trajectory, effectively preventing displacement deviation during movement and improving the smoothness of sliding. Furthermore, the multiple balls in the rolling mechanism reduce the friction between the main bracket and the sliding part body, extending the service life of the lifting bracket. In addition, by simultaneously arranging multiple balls in the rolling mechanism within the first and second guide grooves, the dual-rail design of the prior art is eliminated. This not only simplifies the assembly process of the lifting bracket but also significantly saves assembly costs and manpower, improving production efficiency.
[0074] This application embodiment also provides a display device, which may include: a lifting bracket 000 as described above, and a display (not shown) connected to a connector 202 in the lifting bracket 000. Please refer to... Figure 8 and Figure 9 , Figure 9 This is a partial schematic diagram of a display device provided in an embodiment of this application. The connector 202 may include: a connector body 2021, a rotating shaft 2022, and a fixing plate 2023. The connector body 2021 and the fixing plate 2023 are rotatably connected via the rotating shaft 2022. One end of the connector body 2021 facing away from the fixing plate 2023 is connected to the sliding part body 201. The side of the fixing plate 2023 facing away from the connector body 2021 is used to fix the display. Thus, by rotating the fixing plate 2023 and the rotating shaft 2022, the user can adjust the tilt angle of the display according to personal preference or visual comfort, improving user comfort.
