Description

Technical Field

[0001] The present invention relates to the technical field of display brackets, and in particular to a display lifting bracket. Background Art

[0002] With the rapid development of information technology, monitors have become an indispensable core device in modern office, design, gaming and daily life. Users' demand for monitor experience, especially ergonomic comfort, flexibility and health protection, is increasing.

[0003] Among them, the lifting bracket is an important component of the display, which is used to lift and adjust the display screen so that users can get a good user experience. The conventional lifting bracket mainly includes a base, a column, a support seat and an adjustment module; among them, the column is fixedly set on the base, the support seat is slidably set on the column, and is used for the installation of the display screen, and the adjustment module is connected to the support seat. Usually, the lifting bracket needs to match the weight of the display screen and the supporting force of the adjustment module to achieve force balance and realize the hovering effect of the display screen, thereby meeting the height adjustment requirements of the display screen.

[0004] However, the current monitor lifting bracket still has shortcomings. For example, as DIY assembly becomes more and more popular among consumers, some consumers will choose to replace different display screens on the lifting bracket to meet the needs of product upgrades; but due to the different weights of different models of display screens, there is a weight difference before and after the display screen is replaced. The existing lifting bracket can only support monitors of different weights within a very small weight difference range. When the weight difference of the monitor is too large, the monitor will automatically rise or fall; therefore, the existing technology still lacks a lifting bracket that can conveniently support monitors of various weights, so it needs to be improved.

[0050] In order to make the purposes, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0051] In the description of the present invention, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a centrally located component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be a centrally located component.

[0052] In addition, terms such as "long", "short", "inside", and "outside" indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientation structure, and should not be understood as a limitation of the present invention.

[0053] The following is combined with Figure 1-7 The technical solution of the present invention is further illustrated through specific implementation methods.

[0054] Please refer to Figure 1 and Figure 2 An embodiment of the present invention provides a display lifting bracket, including a bracket body 1, a constant force spring assembly 2, a hook assembly 3 (not shown in the figure) and an unlocking assembly 5 (not shown in the figure).

[0055] Among them, the bracket assembly is used to connect to the display screen. Specifically, the bracket assembly usually includes a base 11, a column 12 and a support seat 13. One end of the column 12 is fixedly connected to the base 11, and the support seat 13 is slidably set on the column 12. The setting method of components such as the base 11, the column 12 and the support seat 13 will not be described in detail here.

[0056] During actual use, the base 11 is placed on the desktop, and the base 11 provides support for the column 12 and the support seat 13. At this time, the column 12 is usually set vertically, and the support seat 13 can be raised and lowered along the length direction of the column 12. The display screen and the support seat 13 are detachably connected. Usually, the two can be detachably connected to each other by setting threaded connectors or quick-release buckles. The lifting bracket and the display screen are combined to form a display. The specific connection method of the two is not limited here. Based on the above setting, the display screen can be raised and lowered under the guidance of the support seat 13.

[0057] Further, refer to Figure 2 and Figure 3 The constant force spring assembly 2 has the ability to output elastic traction force, wherein the constant force spring assembly 2 is detachably arranged on the column 12, and the constant force spring assembly 2 has a retractable connecting portion 26. During the reciprocating extension and contraction of the connecting portion 26, elastic force can be obtained, and the connecting portion 26 is mainly used to connect with the support seat 13. At this time, the constant force spring assembly 2 applies elastic force through the connecting portion 26 to achieve traction on the support seat 13, and then indirectly adjust the lifting and lowering of the display screen through the support seat 13; specifically, in this embodiment, when the constant force spring assembly 2 is installed on the column 12, the support seat 13 is located directly below the constant force spring assembly 2. At this time, the connecting portion 26 can be retracted and extended in the vertical direction, consistent with the lifting and lowering action of the support seat 13, and thus can stably output elastic traction force.

[0058] On this basis, combined with Figure 3 and Figure 4 The hook assembly 3 is arranged on the support seat 13, the connecting part 26 is located on one side of the hook assembly 3, and the hook assembly 3 and the connecting part 26 are movably connected. In addition, the unlocking assembly 5 is arranged on the column 12, and the unlocking assembly 5 cooperates with the hook assembly 3. The unlocking assembly 5 is used to control the mutual unlocking of the hook assembly 3 and the connecting part 26.

[0059] The lifting bracket includes the following two states:

[0060] When the hook assembly 3 and the connecting portion 26 are interlocked, the support base 13 and the connecting portion 26 are fixed. At this time, the constant force spring assembly 2 can apply vertical elastic force to the support base 13 through the connecting portion 26 to achieve the lifting and lowering adjustment function of the display screen.

[0061] When the connecting portion 26 and the hook assembly 3 are loosened from each other, the constant force spring assembly 2 can be further removed from the column 12, and then the constant force spring assembly 2 with different elastic properties can be replaced, and finally it can be adapted to the replacement use of display screens with different weights, and the adaptability of the lifting bracket is optimized and improved.

[0062] To sum up, when it is necessary to install display screens with different weights on the lifting bracket, it is only necessary to operate the unlocking component 5, and then remove the constant force spring component 2 from the column 12, and then directly replace it with a constant force spring component 2 with suitable elastic performance. The process is convenient and fast. Here, by quickly disassembling and replacing the constant force spring component 2, the lifting bracket can be used to support displays of various different weights, which solves the problem that the lifting bracket is difficult to adapt to display screens with different weights.

[0063] Reference Figure 2 and Figure 3 In the embodiment of the present application, in order to improve the overall compactness of the structure, the interior of the column 12 is hollow and the top is open, and the constant force spring assembly 2 is located inside the column 12. In this way, the internal space of the column 12 can be used to accommodate the constant force spring assembly 2, and the compactness of the structure is optimized and improved; specifically, a platform portion 6 is provided at a position near the top of the column 12, and the constant force spring assembly 2 can be disassembled and set on the platform portion 6 through the top opening of the column 12. The platform portion 6 provides assembly support for the constant force spring assembly 2; in addition, there is an insertion and extraction gap 7 between the support seat 13 and the column 12. Specifically, a gap is left between the platform portion 6 and the inner wall of the column 12 on the side away from the display screen to form the insertion and extraction gap 7. The insertion and extraction gap 7 is used for the connection portion 26 to pass through, so as to facilitate the connection between the connection portion 26 and the hook assembly 3.

[0064] Furthermore, a cover plate 14 is detachably provided on the top of the column 12, and the cover plate 14 is used to block the top opening of the column 12. At this time, it can prevent external impurities or foreign objects from entering the column 12, and components such as the constant force spring assembly 2 and the support seat 13 are not easily stuck, and the structure is more stable.

[0065] Among them, in this embodiment, the cover plate 14 is provided with an elastic snap buckle, and correspondingly, a buckle position that is movably connected with the elastic snap buckle is provided on the column 12. At this time, the elastic snap buckle can be used to fix the cover plate 14 to the top of the column 12. When the cover plate 14 needs to be opened, it only needs to pry the cover plate 14, which is convenient and quick to use.

[0066] Reference Figure 5 In an embodiment of the present application, the constant force spring assembly 2 further includes a fixing bracket 21 , a spring mounting seat 22 and a constant force spring 23 .

[0067] Among them, the fixed bracket 21 is detachably connected to the column 12, and the spring mounting seat 22 is arranged on the fixed bracket 21. An assembly station is formed between the spring mounting seat 22 and the fixed bracket 21. At this time, the constant force spring 23 is movably arranged in the assembly station. The fixed bracket 21 and the spring mounting seat 22 are used to limit the constant force spring 23 in the assembly station, so that the constant force spring 23 is not easily loosened outside the assembly station, ensuring that the constant force spring 23 can stably provide elastic force. It can be understood that the constant force spring 23 is a coil spring structure, and the constant force spring 23 has a retractable free end, and the free end forms the connecting part 26 mentioned above. By stretching the free end, the constant force spring 23 can be deformed, and then the elastic force is output.

[0068] In addition, the spring mounting seat 22 has a rectangular structure, and an arc-shaped groove 221 is recessed on the top of the spring mounting seat 22. The constant force spring 23 is placed in the arc-shaped groove 221, and the arc-shaped groove 221 supports the bottom of the constant force spring 23; on this basis, the spring mounting seat 22 and the bottom plate 211 of the fixed bracket 21 are fixed to each other. Usually, screws can be set between the spring mounting seat 22 and the bottom plate 211 to fix the spring mounting seat 22 on the bottom plate 211. On this basis, limit baffles 222 are respectively provided on the opposite sides of the spring mounting seat 22, and the limit baffles 222 limit the two side ends of the constant force spring 23.

[0069] Based on the above structural setting, when the fixed bracket 21, the spring mounting seat 22 and the constant force spring 23 are assembled, the arc groove 221 provides support for the bottom of the constant force spring 23, and the limit baffle 222 limits the two side ends of the positioning spring. At the same time, the top plate 213 of the fixed bracket 21 limits the top of the positioning spring; at this time, under the mutual combination of the spring mounting seat 22 and the fixed bracket 21, one side of the assembly station is open, and the opening part is just used for the free end of the constant force spring 23 to extend, so that the constant force spring 23 is not easy to loosen in the end and can stably output elastic force.

[0070] Continue to refer to Figure 5 In an embodiment of the present application, the constant force spring assembly 2 also includes a threaded fastener 24, which is used to fix the fixing bracket 21 to the column 12. Specifically, the threaded fastener 24 can be a screw. At this time, a mounting hole is opened on the base plate 211 of the fixing bracket 21, and a threaded hole is provided on the column 12. The threaded fastener 24 passes through the mounting hole and is threadedly connected to the threaded hole to achieve a fixed connection of the fixing bracket 21. At this time, by disassembling and assembling the threaded fastener 24, the constant force spring assembly 2 can be disassembled and installed on the column 12. The process is convenient and quick, and the connection stability is good.

[0071] Furthermore, the specific number of threaded fasteners 24 can be set to multiple groups, such as two groups, three groups or four groups, etc., and multiple groups of threaded fasteners 24 can be respectively arranged on opposite sides of the fixed bracket 21. Multiple threaded fasteners 24 can play the role of multi-point reinforcement of the constant force spring assembly 2, making the installation of the constant force spring assembly 2 more stable. It can be understood that the specific setting number of threaded fasteners 24 can be adjusted according to actual needs, and there is no limit on the setting number of threaded fasteners 24 here.

[0072] Reference Figure 5 In an embodiment of the present application, the constant force spring assembly 2 also includes a slider 25. Specifically, the slider 25 shown in this embodiment is a rectangular plate. The slider 25 is vertically arranged during installation. The free end of the constant force spring 23 is fixed to the slider 25 by a screw. At the same time, a buckling hole 261 is provided on the connecting portion 26. The buckling hole 261 is horizontally penetrated on the connecting portion 26. The hook assembly 3 is movably buckled with the buckling hole 261. When the hook assembly 3 is buckled with the buckling hole 261, the connecting portion 26 and the support seat 13 are fixed to each other.

[0073] On this basis, a positioning groove 251 is provided on the slider 25. Specifically, the positioning groove 251 is recessed on the side of the slider 25 facing away from the display screen. At this time, the slider 25 is movably inserted and removed from the plug-in gap 7, and the insertion can drive the connecting portion 26 to be inserted into the plug-in gap 7; and the extension direction of the positioning groove 251 is consistent with the plug-in direction of the slider 25, that is, the positioning groove 251 extends along the vertical direction. In addition, the outer combination Figure 3 A guide protrusion 121 is provided inside the column 12. Specifically, the guide protrusion 121 is provided on the inner wall of the column 12 away from the display screen, and the position of the guide protrusion 121 corresponds to the position of the positioning groove 251. When the slider 25 is inserted into the plug-in gap 7, the guide protrusion 121 can be embedded in the positioning groove 251, and the guide protrusion 121 and the positioning groove 251 slide and cooperate with each other.

[0074] Based on the above setting, when the slider 25 is inserted into the plug-in gap 7, the column 12 will block the snap-on hole 261 and the hook assembly 3. At this time, the mutual cooperation between the positioning groove 251 and the guide protrusion 121 can provide precise positioning for the connection between the slider 25 and the hook assembly 3, and a blind hook effect can be achieved without the need for additional alignment of the hook assembly 3.

[0075] It can be understood that in other embodiments, the setting positions of the positioning groove 251 and the guide protrusion 121 can be swapped with each other. For example, the positioning groove 251 is recessed on the inner wall of the column 12, and the guide protrusion 121 is set on the slider 25. There is no restriction on the specific setting positions of the positioning groove 251 and the guide protrusion 121. No matter what setting combination is adopted, it should be included in the scope of interpretation of this solution.

[0076] In addition, during the unlocking process, it is necessary to press down the slider 25 in advance and then operate the unlocking component 5. In this way, the snap-on hole 261 can be moved down a certain distance before operating the unlocking component 5, so that the constant force spring component 2 and the hook component 3 can be loosened from each other, so that the hook component 3 and the snap-on hole 261 can be loosened from each other later, and the unlocking action can be performed more smoothly.

[0077] Reference Figure 6 and Figure 7 In the embodiment of the present application, the hook assembly 3 includes a rotating shaft 31 , a base plate 32 , a hook portion 33 and a torsion spring 34 .

[0078] Among them, the rotating shaft 31 is arranged in the supporting seat 13, and the base plate 32 is rotatably connected to the rotating shaft 31. Specifically, the two ends of the rotating shaft 31 are respectively fixedly connected to the supporting seat 13. At this time, one side of the base plate 32 is provided with a bending portion by bending, and the bending portion is a cylindrical structure. The rotating shaft 31 passes through the bending portion, and the rotating shaft 31 slides and abuts against the inner wall of the bending portion. Based on the above arrangement, the base plate 32 can swing back and forth under the guidance of the bending portion.

[0079] Furthermore, the substrate 32 is designed to be bent, wherein the upper half of the substrate 32 is a bending portion, and the bending portion is bent toward the inside of the support seat 13. Based on the above arrangement, the substrate 32 can play a role of being away from the slider 25, so that the substrate 32 can be structurally avoided, effectively preventing the substrate 32 from interfering with other components, the movement of the substrate is not easily hindered, the snapping action is more in place, and more reliable.

[0080] At the same time, the hook portion 33 is provided on the base plate 32. Specifically, the hook portion 33 is integrally connected to the side of the base plate 32 close to the connecting portion 26 and is located at the bent portion of the base plate 32. At this time, an escape hole is provided through the support seat 13, and the hook portion 33 passes through the escape hole to the outside of the support seat 13, and can then be movably engaged with the engaging hole 261.

[0081] In addition, the torsion spring 34 is connected to the base plate 32 and the support seat 13 respectively to provide elastic force for the base plate 32. Specifically, the torsion spring 34 is sleeved on the rotating shaft 31, and the two ends of the torsion spring 34 are respectively in contact with the base plate 32 and the support seat 13. The torsion spring 34 has at least the following states:

[0082] When the torsion spring 34 is in a normal state, that is, when the torsion spring 34 is not subjected to external force, the torsion spring 34 fits the substrate 32 against the inner wall of the support seat 13. At this time, the hook portion 33 extends to the outside of the support seat 13, thereby being able to keep the hook portion 33 and the connecting portion 26 interlocked, and the structure is stable.

[0083] When the torsion spring 34 is in a compressed state, that is, when the torsion spring 34 is under pressure, for example, when the base plate 32 swings toward the side away from the connecting portion 26 under the action of an external force, the hook portion 33 retracts into the inside of the support seat 13, thereby enabling the hook portion 33 and the connecting portion 26 to be loosened from each other. At this time, the connecting portion 26 and the supporting seat 13 can be loosened from each other, so as to facilitate further disassembly of the constant force spring assembly 2.

[0084] Based on the above arrangement, the connection portion 26 and the support seat 13 can be fixed to or unlocked from each other by controlling the swing position of the substrate 32 . The action switching is fast and convenient, and a quick-release effect can be achieved.

[0085] Further, refer to Figure 7 In order to reduce the difficulty of installation between the connecting portion 26 and the supporting seat 13, the hook portion 33 has a guiding inclined surface 331. Specifically, the hook portion 33 is bent toward the direction in which the slider 25 is inserted into the plug-in gap 7. At this time, the guiding inclined surface 331 is formed above the hook portion 33, and the guiding inclined surface 331 can slide and abut against the connecting portion 26.

[0086] Based on the above arrangement, when the connecting portion 26 is inserted into the supporting seat 13 through the plug-in gap 7, it can push the substrate 32 to avoid; specifically, it can push the substrate 32 to rotate toward the inside of the supporting seat 13, thereby driving the hook portion 33 to leave the plug-in gap 7. When the connecting portion 26 is inserted into place, the hook portion 33 is arranged opposite to the snap-on hole 261. At this time, the torsion spring 34 releases the elastic force again and drives the hook portion 33 to be inserted into the snap-on hole 261 until the hook portion 33 is snapped with the connecting portion 26.

[0087] Based on the above arrangement, in the process of force-coupling the connecting portion 26 and the supporting seat 13, the hook assembly 3 can lock the connecting portion 26 by itself, and the installation process is convenient, fast and easy to operate.

[0088] Reference Figure 6 The unlocking assembly 5 includes a button element 51 and an elastic element 52. The column 12 is provided with an assembly hole (not shown in the figure). Specifically, the assembly hole is located on the side of the column 12 away from the display screen. At this time, the button element 51 is movably provided on the assembly hole and cooperates with the base plate 32. In this embodiment, the base plate 32 is provided with a connecting rod portion 35 (combined with the connecting rod portion 35) extending toward the button element 51. Figure 7 ), and the connecting rod portion 35 is in contact with the button element 51. By pressing the button element 51, the connecting rod portion 35 can be rotated toward the inside of the support seat 13, thereby realizing the unlocking action. The process is convenient and quick.

[0089] Furthermore, the elastic element 52 is connected to the button element 51 and the column 12 respectively, and is used to provide a restoring elastic force for the button element 51 so that the button element 51 can rebound by itself after being pressed.

[0090] Optionally, in one embodiment, the elastic element 52 may be a spring, and by connecting both ends of the spring to the button element 51 and the column 12 , a reset elastic force can be provided to the button element 51 .

[0091] In the embodiment provided in the present application, the elastic element 52 includes a first elastic piece 521 and a second elastic piece 522, wherein the first elastic piece 521 and the second elastic piece 522 can be made of metal or plastic material with rebound performance, and the specific material of the first elastic piece 521 and the second elastic piece 522 is not limited here.

[0092] Based on this, the first spring piece 521 is connected to one side of the button element 51, and the second spring piece 522 is connected to the other side of the button element 51.
