Description

Technical Field

[0001] This utility model relates to the field of display screen bracket technology, and in particular to a display screen bracket and a portable screen. Background Technology

[0002] With the rapid development of technology and the growing demand for mobile office and personalized entertainment, portable screens have emerged. Compared to traditional desktop monitors, portable screens, with their lightweight, portability, and flexible use, not only overcome the shortcomings of bulky and limited-use traditional monitors, but also seamlessly connect with devices such as mobile phones, providing more possibilities and choices for modern people's work efficiency and entertainment experience.

[0003] There are three main types of traditional portable screen stands:

[0004] (1) A dedicated bracket can meet the needs of horizontal and vertical support, but it requires additional accessories and the bracket is bulky and inconvenient to carry.

[0005] (2) Integrated folding stand: It is integrated with the portable screen and forms a support by folding or unfolding. It usually has a damping design for easy storage, but it can only achieve free adjustment within the range of 0-80° and a single support mode, and cannot achieve free switching between horizontal and vertical screens.

[0006] (3) Protective case / leather case support: The protective case / leather case folds into a triangular structure to support the screen. It is lightweight but generally not very stable, has a single angle, and is prone to wear and tear.

[0007] In summary, traditional portable screen stands have limited adjustable angles, cannot freely switch between portrait and landscape modes, and require additional accessories to achieve various support modes, resulting in insufficient portability.

[0008] Therefore, there are still shortcomings and deficiencies in the existing technology. How to provide a display stand that can achieve 360° stepless adjustment and arbitrary angle suspension, and can freely switch between horizontal and vertical screens, as well as a portable screen, is a technical problem that urgently needs to be solved by those skilled in the art.

[0026] This utility model also provides a portable screen, including the display screen bracket provided by any of the above technical solutions.

[0027] Compared to the aforementioned background technology, the display screen bracket provided by this utility model has a secondary connecting rod connected to the bracket base and the main connecting rod via a damping pivot.

Detailed Implementation

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] This utility model provides a display screen bracket that, through the cooperation of the rotation damping module 30 and the bracket connecting rod module 20, supports 360° stepless adjustment and arbitrary angle suspension, enabling free switching between landscape and portrait modes.

[0043] Please refer to this as well. Figures 1 to 9 The display screen bracket provided by this utility model includes:

[0044] The support linkage module 20 is used to realize the folding and unfolding of the support. The support linkage module 20 includes a support base 21, at least one secondary linkage 22 and at least one main linkage 23. The secondary linkage 22 is connected to the support base 21 and the main linkage 23 is connected to the secondary linkage 22 through a damping shaft 24.

[0045] The rotation damping module 30 is used to realize the 360° stepless adjustment and arbitrary angle suspension of the bracket. The rotation damping module 30 includes a base 31, a mounting part 34 provided on the base 31, and at least one rotating shaft 35 provided on the mounting part 34. The rotating shaft 35 is fixedly connected to the main connecting rod 23.

[0046] The mounting component 34 is configured to be rotatably connected to the base 31 with damping, and the rotating shaft 35 is configured to be rotatably connected to the mounting component 34 with damping.

[0047] The rotation damping module 30 and the support link module 20 are assembled through the connection of the pivot 35 and the main link 23. In use, the rotation damping module 30 is assembled on the portable screen 10. The secondary link 22 is connected to the support base 21 and the main link 23 through the damping pivot 24. The rotation angle of the secondary link 22 and the main link 23 can be adjusted by the damping pivot 24, allowing it to be suspended at any angle and folded or unfolded. The mounting part 34 can rotate with damping in a direction parallel to the screen plane of the portable screen 10 to switch between landscape and portrait modes. The pivot 35 can rotate with damping in a direction perpendicular to the screen plane of the portable screen 10 to adjust the tilt angle of the portable screen 10, thereby achieving 360° stepless adjustment and suspension at any angle.

[0048] With this configuration, the rotation damping module 30 and the bracket linkage module 20 work together to support 360° stepless adjustment and arbitrary angle suspension, enabling free switching between landscape and portrait modes. Multiple support modes can be achieved without additional accessories, meeting the needs of various application scenarios.

[0049] In some embodiments, the rotational damping module 30 further includes:

[0050] Fixing element 32 is provided on base 31;

[0051] The elastic element 33 is disposed between the fixing element 32 and the mounting element 34;

[0052] The pressure plate 36 is used to press the rotating shaft 35, and the pressure plate 36 is connected to the mounting part 34 via the fastener 37.

[0053] The mounting component 34 has a guide hole 341 on the side away from the fixing component 32, and the rotating shaft 35 passes through the guide hole 341.

[0054] Please refer to this as well. Figures 1 to 5 The fixing component 32 and the mounting component 34 are sheet-like structures made of metal. The fixing component 32, the elastic component 33 and the mounting component 34 are integrated with the base 31 by stamping. The fixing component 32, the elastic component 33 and the mounting component 34 are clamped between the upper and lower surfaces of the base 31. The elastic component 33 is located between the fixing component 32 and the mounting component 34, so that the mounting component 34 is connected to the base 31 with damping through the elastic component 33. Thus, the mounting component 34 can rotate with damping in a direction parallel to the screen plane of the portable screen 10, realizing the switching between landscape and portrait modes.

[0055] The rotating shaft 35 passes through the guide hole 341 on the mounting member 34, which allows the rotating shaft 35 to rotate. The pressure plate 36 presses the rotating shaft 35 onto the mounting member 34 and connects it through the fastener 37. When the rotating shaft 35 wants to rotate, it must overcome the friction between the pressure plate 36 and the surface of the mounting member 34. The damping of the rotating shaft 35 during rotation is provided by the pressure plate 36, the mounting member 34 and the fastener 37, so that the rotating shaft 35 can rotate with damping in a direction perpendicular to the screen plane of the portable screen 10, thereby adjusting the tilt angle of the portable screen 10.

[0056] Specifically, in this embodiment, the fastener 37 is a screw. When the screw is tightened properly, the pressure plate 36 will be pressed down, thereby pressing the rotating shaft 35 onto the mounting member 34. When the rotating shaft 35 rotates, it needs to overcome the friction between the pressure plate 36 and the surface of the mounting member 34, thereby connecting the rotating shaft 35 to the mounting member 34 with damping.

[0057] With this configuration, the bracket can rotate with damping in both directions perpendicular to the screen plane of the portable screen 10 and parallel to the screen plane of the portable screen 10, thereby achieving 360° stepless adjustment and arbitrary angle suspension through the cooperation of the pivot 35 and the mounting part 34.

[0058] In some embodiments, the fastener 32 is provided with a plurality of positioning mounting holes 321 along the circumferential direction. Some of the positioning mounting holes 321 are used for positioning and assembly with the positioning post 11 on the bottom shell of the portable screen 10, and other positioning mounting holes 321 are used for cooperating with the mounting holes 12 on the bottom shell of the portable screen 10.

[0059] Please refer to this as well. Figures 2 to 5 The positioning mounting holes 321 are evenly distributed along the circumference of the fixing member 32. When the rotation damping module 30 is assembled with the portable screen 10, the positioning posts 11 on the bottom shell of the portable screen 10 are correspondingly accommodated in some of the positioning mounting holes 321 for positioning. The mounting holes 12 on the bottom shell of the portable screen 10 coincide with other positioning mounting holes 321, which facilitates the subsequent reliable connection between the rotation damping module 30 and the portable screen 10 through the connector.

[0060] Specifically, in this embodiment, there are four positioning mounting holes 321, which are evenly distributed circumferentially. Two of the relatively opposite positioning mounting holes 321 are positioned and assembled with two positioning posts 11 on the bottom shell of the portable screen 10, while the other two relatively opposite positioning mounting holes 321 are connected to mounting holes 12 on the bottom shell of the portable screen 10 via connectors. This arrangement ensures that the load borne by each connector connecting the portable screen 10 and the fixing member 32 is relatively uniform, avoiding situations where some connectors are overloaded while others are not fully utilized, thereby improving the overall connection strength and ensuring the stability and safety of the assembly. In other embodiments, the number of positioning mounting holes 321 can also be set according to the actual portable screen 10 to be assembled, and there is no specific limitation.

[0061] In some embodiments, the positioning mounting hole 321 is connected to the mounting hole 12 on the bottom shell of the portable screen 10 by screws or bolts.

[0062] Please refer to this as well. Figures 2 to 5 In this embodiment, the positioning mounting hole 321 on the fixing member 32 and the mounting hole 12 on the bottom shell of the portable screen 10 are connected by screws, thereby achieving a reliable connection between the rotation damping module 30 and the portable screen 10. In other embodiments, the positioning mounting hole 321 and the mounting hole 12 on the bottom shell of the portable screen 10 can also be connected by bolts or the like, which not only ensures a reliable connection but also facilitates disassembly.

[0063] In some embodiments, the elastic element 33 is a spring sheet.

[0064] Please refer to Figure 3 The spring is not a flat pad, but an elastic metal sheet with a wavy or special raised structure. The spring is clamped between the fixing member 32 and the mounting member 34. When the mounting member 34 rotates, the mounting member 34 needs to overcome the friction between itself and the top surface of the base 31, the spring and the mounting member 34 and the fixing member 32 in order to rotate. The aforementioned friction provides damping when the mounting member 34 rotates, so that the mounting member 34 can rotate with damping in a direction parallel to the screen plane of the portable screen 10, realizing the switching between landscape and portrait modes.

[0065] In some embodiments, there are two secondary connecting rods 22 and two main connecting rods 23. The two secondary connecting rods 22 are symmetrically arranged on both sides of the support base 21, and the two main connecting rods 23 are respectively arranged on the two secondary connecting rods 22.

[0066] In some embodiments, there are two rotating shafts 35, which are symmetrically arranged on the mounting member 34.

[0067] In some embodiments, one end of each of the two rotating shafts 35 is fixedly connected to one of the two main connecting rods 23.

[0068] Please refer to this as well. Figures 1 to 5 Two auxiliary connecting rods 22 are symmetrically arranged on both sides of the support base 21, and two main connecting rods 23 are respectively arranged on the two auxiliary connecting rods 22. The rotation damping module 30 is located between the two main connecting rods 23. The two rotating shafts 35 in the rotation damping module 30 are fixedly connected to the two main connecting rods 23 respectively, thereby realizing the assembly of the support connecting rod module 20 and the rotation damping module 30.

[0069] Specifically, in this embodiment, the main connecting rod 23 has an assembly hole along its extension direction. The assembly hole is oblong in shape, and the shape and size of the end of the rotating shaft 35 are adapted to the shape and size of the assembly hole. The rotating shaft 35 is inserted into the assembly hole and has an interference fit with the assembly hole, thereby realizing the connection between the main connecting rod 23 and the rotating shaft 35. The rotating shaft 35 and the assembly hole can also be fitted with a clearance fit. In this case, additional fastening components are needed to fasten the rotating shaft 35 and the main connecting rod 23 to ensure the reliability and stability of the connection. The fastener 37 can be a fastening bolt or a fastening pin, etc.

[0070] In some embodiments, when the support linkage module 20 is in the folded storage state, the support linkage module 20 and the rotation damping module 30 are fitted into the portable screen 10 to form a hidden structure.

[0071] Please refer to Figure 6 When the bracket linkage module 20 is in the folded storage state, the bracket linkage module 20 and the rotation damping module 30 are deeply embedded with the bottom shell of the portable screen 10. This setting reduces the volume occupied, making the overall structure of the portable screen 10 more compact. Moreover, only the plate-shaped bracket base 21 is exposed, while the other parts of the bracket are completely covered by the bracket base 21, which does not affect the overall aesthetics of the portable screen 10.

[0072] The display screen bracket provided by this utility model allows for selection of different support states according to the application scenario. The support state can be selected by adjusting the rotation angle and opening angle of the bracket connecting rod module 20 and the rotation damping module 30.

[0073] like Figure 7 As shown, when vertically supported, after the bracket is unfolded, the rotation damping module 30 rotates 90° counterclockwise, and the secondary connecting rod 22 and the main connecting rod 23 are on the same straight line after opening and closing, and the portable screen 10 is supported by the bracket base 21.

[0074] like Figure 8 As shown, during lateral support, after the bracket is deployed, the rotation damping module 30 does not need to rotate, and the main connecting rod 23 and the auxiliary connecting rod 22 do not need to open or close. Lateral support can be achieved by adjusting the opening and closing angle of the bracket base 21.

[0075] like Figure 9As shown, during the lifting support, after the bracket is unfolded, the rotation damping module 30 does not need to rotate, the main connecting rod 23 remains stationary, and the opening and closing angle of the secondary connecting rod 22 is adjusted to move the portable screen 10 up and down to the height required for use, thus achieving the lifting support.

[0076] Please refer to this as well. Figures 6 to 9 In addition to the display screen brackets disclosed in the above embodiments, this utility model also provides a portable screen 10 including the above display screen brackets.

[0077] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0078] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
