[0041] As described in the background technology, the desktop display screen in the related technology has the problem of inconvenient operation when rotating. After research by technicians, it was found that the reason for this problem is that the existing technology uses a pressure bearing to provide damping force for the rotation of the display screen. The force required for the forward rotation of the display screen and the reverse rotation of the display screen is the same. When rotating in the reverse direction, it is necessary to pinch the display screen to apply force, which causes inconvenience in operation; and because the friction contact surface of the rotating shaft is an inclined surface during rotation, the greater the rotation angle, the greater the interference, the greater the damping, and the greater the force required for the display screen to rotate in the reverse direction (return). At the same time, when rotating in the reverse direction, the base is prone to warping together with the display screen. At this time, it is necessary to add a counterweight block and a suction cup to the base to prevent the base from warping, resulting in a complex overall structure.

[0042] In response to the above technical problems, an embodiment of the present application provides a support structure, which adopts a dual design of a pressure bearing and a spring, and utilizes the damping force of the pressure bearing and the rebound force of the spring to design a rotating shaft with bidirectional different torques. The rotating shaft can provide a uniform forward thrust (damping force + rebound force), and has a good feel when used in the forward direction. When the stylus is clicked, it can remain in the rotated position without moving, which conforms to the ergonomic feel and the holding force of the stylus when in use; when adjusting in the reverse direction, just touch the rebound (damping force - rebound force), which is light and fast, and greatly improves the product function and usage experience.

[0043] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0044] The present application embodiment provides a support structure, referring to Figures 1 to 8 , Figure 1 This is a schematic diagram of the three-dimensional structure of the desktop display device provided in the embodiment of the present application. Figure 2 for Figure 1 The local enlarged area A in Figure 3 This is a schematic diagram of the main structure of the desktop display device provided in an embodiment of the present application. Figure 4 for Figure 3 The local enlarged area B in Figure 5 This is a schematic diagram of a top view of the desktop display device provided in an embodiment of the present application. Figure 6 for Figure 5 The local enlarged area C in Figure 7 This is a schematic diagram of the right side structure of the desktop display device provided in an embodiment of the present application. Figure 8 for Figure 7The support structure is rotatably connected to the display screen 100. When the user applies force to the display screen 100, the display screen 100 rotates around the first horizontal axis ( Figure 2 and Figure 4 The X-axis shown in FIG. 1 is rotated.

[0045] The supporting structure includes: a bracket 300 , a rotating shaft 400 , a torsion spring 500 and a pressure bearing 600 .

[0046] The bracket 300 has a first mounting through hole, the central axis of which is along a first horizontal direction ( Figure 2 and Figure 4 The X direction shown in FIG. 1 extends.

[0047] The axis of the rotating shaft 400 is along the first horizontal direction ( Figure 2 and Figure 4 The rotating shaft 400 is rotatably connected in the first mounting through hole; the rotating shaft 400 has one end and the other end ( Figure 4 One end of the rotating shaft 400 passes through the first mounting through hole and is fixedly connected to the supported member (that is, the display screen 100 ), and the pressure bearing 600 is sleeved on the other end of the rotating shaft 400 .

[0048] The torsion spring 500 has a first end 501 and a second end 502, the first end 501 is fixedly connected to the bracket 300, and the second end 502 is fixedly connected to the other end of the rotating shaft 400; and the pressure bearing 600 is located between the first mounting through hole and the second end 502, that is, the pressure bearing 600 is located between the bracket 300 and the second end 502.

[0049] The torsion spring 500 includes an initial state, a compressed state, and a rebound state.

[0050] When the torsion spring 500 is in the initial state, the torsion spring 500 is not compressed, the display screen 100 is stationary at the initial position, and the starting force required to rotate the display screen 100 (that is, to rotate the rotating shaft 400 ) is the damping force provided by the pressure bearing 600 .

[0051] When the torsion spring 500 is in a compressed state, the user is applying force to the display screen 100, and the force required for the rotation of the shaft 400 = the shaft torque provided by the pressure bearing 600 + the rebound force provided by the torsion spring 500 after compression, so that the shaft 400 drives the display screen 100 to rotate around the first horizontal direction ( Figure 2 and Figure 4 The display screen 100 is rotated clockwise by a preset angle (in the X direction shown in FIG. 1 ), so that the display screen 100 remains stationary at a preset position.

[0052] When the torsion spring 500 is in the rebound state, the user is applying force to the display screen 100, and the force required for the rotation of the shaft 400 = the shaft torque provided by the pressure bearing 600 - the rebound force provided by the torsion spring 500 after compression (because the rebound force of the torsion spring 500 is in the same direction as the force applied by the user at this time), so that the shaft 400 drives the display screen 100 to rotate counterclockwise around the first horizontal direction at a preset angle, so that the display screen 100 remains stationary at the initial position.

[0053] The supporting structure provided by the embodiment of the present application includes: a bracket 300, a rotating shaft 400, a torsion spring 500 and a pressure bearing 600, the bracket 300 has a first mounting through hole, the central axis of the first mounting through hole is along the first horizontal direction ( Figure 2 and Figure 4 The rotating shaft 400 is rotatably connected in the first mounting through hole, and one end of the rotating shaft 400 passes through the first mounting through hole and is fixedly connected to the display screen 100; the first end 501 of the torsion spring 500 is fixedly connected to the bracket 300, and the second end 502 of the torsion spring 500 is fixedly connected to the other end of the rotating shaft 400; the pressure bearing 600 is sleeved on the other end of the rotating shaft 400, and the pressure bearing 600 is located between the first mounting through hole and the second end 502; when the torsion spring 500 is in a compressed state, the force required for the rotation of the rotating shaft 400 = the rotating shaft torsion provided by the pressure bearing 600 + the rebound force provided by the torsion spring 500 after compression, so that the rotating shaft 400 drives the display screen 100 to rotate clockwise around the first horizontal direction at a preset angle; when the torsion spring 500 is in a rebound state, the force required for the rotation of the rotating shaft 400 = the rotating shaft torsion provided by the pressure bearing 600 - the rebound force provided by the torsion spring 500 after compression, so that the rotating shaft 400 drives the display screen 100 to rotate counterclockwise around the first horizontal direction at a preset angle. The supporting structure adopts a dual design of a pressure bearing 600 and a torsion spring 500. The damping force of the pressure bearing 600 and the rebound force of the torsion spring 500 are used to design a rotating shaft 400 with bidirectional different torques. The rotating shaft 400 can provide a uniform forward thrust (damping force + rebound force), and has a good feel when used in the forward direction. When the stylus is clicked, it can remain in the rotated position without moving, which conforms to the ergonomic feel and the holding force of the stylus when in use; when adjusting in the reverse direction, just touch the rebound (damping force - rebound force), which is light and fast, greatly improving the product function and user experience.

[0054] In the embodiment of the present application, when the torsion spring 500 is in a compressed state, the force required for the rotation of the rotating shaft 400 is greater than 4N. When the display screen 100 is clicked with a stylus, the force is 4N. When the force required for the rotation of the rotating shaft 400 is greater than 4N, the display screen 100 does not rotate.

[0055] At the same time, when the torsion spring 500 is in the rebound state, the force required for the rotation of the shaft 400 is greater than 0N. If the damping force provided by the pressure bearing 600 is less than the rebound force of the torsion spring 500, the display screen 100 will return to the initial state after the user lets go, which does not meet the usage standards. Therefore, the force required for the rotation of the shaft 400 is greater than 0N.

[0056] It should be noted that technicians can design different types of pressure bearings 600 and torsion springs 500 according to actual needs to adapt to various situations.

[0057] In the embodiment of the present application, the bracket 300 includes a horizontal plate 301 and a vertical plate 302 connected vertically, the horizontal plate 301 is horizontally arranged, and the vertical plate 302 is provided with a first mounting through hole 3021 and a second mounting through hole 3022, the central axes of the first mounting through hole 3021 and the second mounting through hole 3022 both extend along the first horizontal direction (X direction), the first mounting through hole 3021 and the second mounting through hole 3022 are spaced apart along the vertical direction (Z direction), and the first mounting through hole 3021 is close to the top of the vertical plate 302, and the second mounting through hole 3022 is located in the middle position of the vertical plate 302.

[0058] One end of the rotating shaft 400 passes through the first mounting through hole 3021 and is fixedly connected to the display screen 100, and the other end of the rotating shaft 400 is provided with a third mounting through hole, and the central axis of the third mounting through hole extends along the vertical direction (Z direction); the first end 501 is fixedly connected to the second mounting through hole 3022, and the second end 502 is fixedly connected to the third mounting through hole, so that the torsion spring 500 is connected to both the bracket 300 and the rotating shaft 400. When the rotating shaft 400 rotates, it will drive the torsion spring 500 to be compressed, and when the torsion spring 500 rebounds, it can also drive the rotating shaft 400 to rotate.

[0059] In an embodiment of the present application, the support structure also includes a base plate 200, which is horizontally arranged and a transverse plate 301 is fixedly connected to the base plate 200; wherein the transverse plate 301 is fixedly connected to the base plate 200 by screws to ensure the stability of the connection between the bracket 300 and the display screen 100.

[0060] In the embodiment of the present application, the support structure further comprises a first wear-resistant gasket 801, which is sleeved on the other end of the rotating shaft 400 and located between the vertical plate 302 and the pressure bearing 600, providing a wear-resistant surface for the rotating shaft 400 during rotation.

[0062] In the embodiment of the present application, the support structure further includes a third wear-resistant gasket 803 and a fastening nut 900, both of which are sleeved on the other end of the rotating shaft 400, the fastening nut 900 is close to the end of the other end of the rotating shaft 400, and the third wear-resistant gasket 803 is located between the second end 502 and the fastening nut 900. A wear-resistant surface is further provided for the rotating shaft 400 during the rotation process, while ensuring the stability of the overall structure.

[0064] The limiting piece 700 can limit the rotation angle of the rotating shaft 400 to meet the requirements of different products; at the same time, it prevents the rotation angle of the rotating shaft 400 from exceeding the elastic force limit of the torsion spring 500, causing the torsion spring 500 to fail.

[0065] In the embodiment of the present application, the pressure bearing 600 includes a first pressure bearing and a second pressure bearing, and the first pressure bearing and the second pressure bearing are sequentially sleeved on the other end of the rotating shaft along the first horizontal direction.

[0066] An embodiment of the present application also provides a desktop display device, which includes the support structure described above and also includes a display screen 100; the display screen 100 is fixedly connected to one end of a rotating shaft 400, and the rotating shaft 400 can drive the display screen 100 to rotate clockwise or counterclockwise around a first horizontal direction at a preset angle.
