[0037] As an important medical device, the rationality of the design and ease of operation of the disinfection machine directly affect the work efficiency of medical institutions and the user experience. In order to ensure that every operator can obtain a comfortable viewing angle, the relevant technology adopts a design in which the display screen and the body of the disinfection machine are separated, and is equipped with a rotating shaft to adjust the angle of the display screen. However, in the existing separate design, the display screen support device usually adopts a straight-axis structure, which makes it difficult to ensure the consistency of the damping force value of the shaft after each assembly. Manual adjustment is usually required, which reduces the manufacturability of the display screen support device. In addition, the shaft of the straight-axis structure is prone to deflection and has poor stability. The straight-axis structure easily exposes the external wiring of the display screen, affecting the overall appearance.

[0038] In order to solve all or part of the technical problems in the above-mentioned related devices, an embodiment of the present invention provides a display screen support device. The display screen support device can be set on the side of the display screen away from the screen, and can include a shaft base 1, a first shaft assembly 2 and a second shaft assembly 3; the shaft base 1 can include a support section 11 and a shaft connecting section 12, and the support section 11 is used to be fixedly connected to the supporting mechanism of the display screen; the first shaft assembly 2 can be set on one side of the shaft connecting section 12, and the first shaft assembly 2 can include a first damping shaft 21 and a first connecting piece 22, the fixing seat of the first damping shaft 21 is fixedly connected to the display screen, the shaft core of the first damping shaft 21 is fixedly connected to the first connecting piece 22, and the first connecting piece 22 is fixedly connected to the support mechanism of the display screen. The shaft base 1 is fixedly connected; the second shaft assembly 3 can be arranged on the side of the shaft connecting section 12 away from the first shaft assembly 2, the second shaft assembly 3 includes a second damping shaft 31 and a second connecting piece 32, the fixing seat of the second damping shaft 31 is fixedly connected to the display screen, the shaft core of the second damping shaft 31 is fixedly connected to the second connecting piece, and the second connecting piece 32 is fixedly connected to the shaft base 1; wherein, the axial direction of the shaft core of the first damping shaft 21 coincides with the axial direction of the shaft core of the second damping shaft 31, and when the angle of the display screen changes, the first shaft assembly 2 and the second shaft assembly 3 are driven to rotate synchronously.

[0039] The display screen support device in the above embodiment, on the one hand, through the relatively arranged first damping shaft and the second damping shaft, makes the damping force value of the shaft after the display screen support device is assembled basically consistent, thereby improving its manufacturability and ensuring smoothness and damping feeling during rotation. In addition, the two shafts work synchronously to ensure the consistency of the damping force during rotation, thereby improving the user's operating experience; on the other hand, by setting the first shaft assembly and the second shaft assembly, the weight and rotational force of the display screen are evenly shared by the two shafts, reducing the pressure on a single shaft, effectively avoiding the shaking or deflection problems that may occur in the traditional single shaft design, and improving the stability of the display screen support device; on the other hand, the assembly design of the first shaft assembly and the second shaft assembly makes the shaft assembly easy to disassemble and replace. When one of the shaft assemblies needs maintenance or replacement, it will not affect the function of the entire support device, thereby improving the maintenance efficiency and service life of the equipment.

[0040] refer to Figure 1 As shown, the display screen support device in the present invention may include a hinge base 1, a first hinge assembly 2 and a second hinge assembly 3. The hinge base 1 may include a supporting section 11 and a hinge connecting section 12. The first hinge assembly 2 may include a first damping hinge 21 and a first connecting piece 22. The second hinge assembly 3 may include a second damping hinge 31 and a second connecting piece 32.

[0041] Among them, the shaft base 1, as the basic structural part of the display screen support device, can include a support section 11 and a shaft connecting section 12. The main function of the support section 11 is to be firmly connected to the supporting mechanism of the display screen to ensure the stability of the display screen installation. The supporting mechanism can be an equipment instrument, such as the main unit of a disinfection machine, or other supporting structures such as a bracket or a frame. The shaft connecting section 12 can be used to connect the shaft assembly and the shaft base 1. Since the shaft base 1 needs to support the display screen, its material strength needs to meet the support requirements. For example, the shaft base 1 can be made of aluminum alloy, stainless steel, cast iron, engineering plastics and other suitable materials.

[0042] The first rotating shaft assembly 2 is disposed on one side of the rotating shaft connecting section 12 and includes a first damping rotating shaft 21 and a first connecting piece 22. The fixing base of the first damping rotating shaft 21 can be directly fixedly connected to the back of the display screen, ensuring that the first damping rotating shaft 21 can follow the movement of the display screen. The rotating shaft core of the first damping rotating shaft 21 is fixedly connected to the first connecting piece 22, and the first connecting piece 22 is fixedly connected to the rotating shaft base 1. Specifically, during the rotation of the first damping rotating shaft 21, the rotating shaft core and the first connecting piece 22 are fixed, and the fixing base of the first damping rotating shaft 21 rotates around the rotating shaft core. Furthermore, the shaft core can be fixedly connected to the first connecting piece 22 based on an interference fit. Specifically, the shaft core can be designed to be slightly larger than the diameter of the through hole on the first connecting piece 22. By heating the shaft core or cooling the first connecting piece 22, the shaft core can be pressed into the hole by utilizing the thermal expansion and contraction properties of the material, and a tight fit is formed after the material returns to room temperature. The shaft core can also be threadedly connected to the first connecting piece 22. Specifically, the end of the shaft core close to the first connecting piece 22 can be provided with an external thread, and the first connecting piece 22 is provided with a through hole, and the inner wall of the through hole is provided with an internal thread. The shaft core is fastened to the first connecting piece 22 by screwing. Holes can also be drilled on the shaft core and the first connecting piece 22 respectively, and then pins can be inserted to fix the connection. In addition, the fixed connection between the shaft core and the first connecting piece 22 can also be achieved by other suitable methods such as welding.

[0043] In addition, the first damping shaft 21 may include a fixed seat, a shaft core and a damping element. One end of the fixed seat is fixed to the display screen or other components to be rotated, and the other end is provided with a through hole for the shaft core to pass through, and a damping element is provided on the shaft core adjacent to the fixed seat, so that when the fixed seat of the first damping shaft 21 rotates around the shaft core, a controllable rotational motion can be achieved, and an appropriate damping force is provided during the rotation process, so that the damping force value of the display screen support device after assembly is basically consistent. For example, the damping element can be an elastic element, such as a rubber sheet or a spring, or other suitable elements such as a friction plate. These elements produce a damping effect through their physical properties (such as elastic deformation recovery force). When the first damping shaft 21 rotates with the display screen, the damping element is squeezed or stretched, and the resulting reaction force forms a resistance during the rotation process, ensuring that the rotation action is both smooth and controllable, and avoiding the impact and instability caused by rapid rotation. Furthermore, in order to fine-tune the damping force, damping elements of different hardness or specifications can be provided, for example, using rubber sheets with different elastic coefficients or springs with different numbers of turns and diameters to meet the personalized needs of different users for the rotational damping feeling.

[0044] The second rotating shaft assembly 3 and the first rotating shaft assembly 2 are arranged on both sides of the rotating shaft connecting section 12 opposite each other. The two have similar structures. The second rotating shaft assembly 3 includes a second damping rotating shaft 31 and a second connecting piece 32. The second damping rotating shaft 31 also includes a fixing seat and a rotating shaft core. The fixing seat is fastened to the display screen. The rotating shaft core is connected to the second connecting piece 32, and the second connecting piece 32 is fixed to the rotating shaft base 1. This symmetrical layout ensures that the first rotating shaft assembly 2 and the second rotating shaft assembly 3 can work synchronously and coordinately to jointly support the smooth rotation of the display screen. In addition, it can also evenly share the weight and rotational force of the display screen between the two rotating shafts, reducing the pressure on a single rotating shaft, effectively avoiding the shaking or deflection problems that may occur in traditional single-rotating shaft designs, and improving the stability of the display screen support device.

[0045] refer to Figure 1 As shown, the hinge base 1 may include a threading hole 13, which is set through the hinge base 1. The threading hole 13 is used to pass the external wiring of the display screen, and one end of the threading hole 13 is set at the supporting section 11, and the other end is set at the hinge connecting section 12.

[0046] Specifically, by providing a wire threading hole 13 in the hinge base 1, the power line, signal line and other external wires of the display screen can be passed through the inside of the hinge base 1 in an orderly manner, thereby avoiding exposure of the cables; the cables can also be protected to prevent damage caused by wear or impact; and it can also ensure that when the display screen rotates, the cables will not limit the rotation angle or cause damage due to entanglement or pulling, thereby improving the freedom and flexibility of rotation and thus improving the user experience.

[0047] refer to Figure 1 As shown, in some embodiments, the display screen support device may further include a first accommodating cover 4 and a second accommodating cover 5, wherein the first accommodating cover 4 can be used to accommodate the first hinge assembly 2, and the opening of the first accommodating cover 4 is arranged on the side close to the display screen; the second accommodating cover 5 can be used to accommodate the second hinge assembly 3, and the opening of the second accommodating cover 5 is arranged on the side close to the display screen.

[0048] Specifically, first and second housing covers 4, 5 can be positioned oppositely on either side of hinge base 1, respectively accommodating first hinge assembly 2 and second hinge assembly 3. By enclosing first and second hinge assemblies 2, 3 with first and second housing covers 4, 5, respectively, dust and foreign matter are effectively prevented from entering the hinge assemblies, reducing wear and tear, malfunction rates, and extending service life. Furthermore, the design of the housing covers, such as color and shape, can be coordinated with the overall style of the display, thereby enhancing the product's aesthetics.

[0049] refer to Figure 1 and Figure 2 As shown, the first accommodating cover 4 may include a first shell 41 and a first plug-in portion 42, the first plug-in portion 42 is connected to the inner wall of the first shell 41, and the first plug-in portion 42 includes a first extension section 421 extending from the opening of the first accommodating cover 4; the second accommodating cover 5 may include a second shell 51 and a second plug-in portion 52, the second plug-in portion 52 is connected to the inner wall of the second shell 51, and the plug-in portion includes a second extension section 521 extending from the opening of the second accommodating cover 5.

[0050] Specifically, the design of first extension section 421 and second extension section 521 allows the housing to be easily plugged and fixed to other structural components, facilitating user installation and removal, thereby improving the product's maintainability. Furthermore, the plug-in portion is tightly connected to the inner sidewall of the housing, ensuring a secure and reliable connection between the housing and other structural components when the display rotates. This prevents displacement or disengagement due to vibration or external forces, thereby enhancing the stability of the overall structure.

[0051] In some embodiments, reference Figure 1As shown, the display screen support device may further include a connecting base plate 6, which may be used to realize a fixed connection between the display screen support device and the display screen, and the connecting base plate 6 may include a first plug-in slot 61 and a second plug-in slot 62, wherein the first plug-in slot 61 may be arranged on a side of the connecting base plate 6 close to the first rotating shaft assembly 2, and the first plug-in slot 61 is used to realize a plug-in connection between the connecting base plate 6 and the first accommodating cover 4; the second plug-in slot 62 may be arranged on a side of the connecting base plate 6 close to the second rotating shaft assembly 3, and the second plug-in slot 62 is used to realize a plug-in connection between the connecting base plate 6 and the second accommodating cover 5; when the first accommodating cover 4 is inserted into the first plug-in slot 61, the outer side wall of the first extension section 421 is fitted with the inner side wall of the first plug-in slot 61; when the second accommodating cover 5 is inserted into the second plug-in slot 62, the outer side wall of the second extension section 521 is fitted with the inner side wall of the second plug-in slot 62.

[0052] Specifically, the connecting base plate 6 can be fixed to the back of the display screen by screws, thereby achieving a fixed connection between the display screen support device and the display screen. For example, by aligning the mounting holes preset on the back of the display screen with the corresponding holes on the connecting base plate 6, the display screen is directly fixed to the connecting base plate 6 using screws. Of course, in other embodiments of the present invention, the connecting base plate 6 can also be fixed to the display screen by other suitable means such as quick-release buckles, mortise and tenon structures, etc.

[0053] Furthermore, the plug-in connection between the first housing cover 4 and the first insertion slot 61, and the plug-in connection between the second housing cover 5 and the second insertion slot 62, ensures a tight and stable assembly between the housing cover and the connecting base plate 6, reduces the possibility of loosening, and enhances the stability of the display support device. Furthermore, installation is completed by simply aligning the extension section with the corresponding insertion slot, without the need for additional fasteners such as screws. This significantly shortens installation time, improves installation efficiency, and facilitates disassembly. Furthermore, the plug-in connection ensures precise alignment between the first housing cover 4 and the first insertion slot 61, and the second housing cover 5 and the second insertion slot 62, without exposed fixing screws or gaps, thereby enhancing the aesthetics of the device.

[0054] In addition, in some embodiments, the first accommodating cover 4 and the second accommodating cover 5 are respectively provided with notches on one side close to the rotating shaft base 1. When the accommodating cover and the plug-in slot are connected, the notch can provide accommodation and movement space for the rotating shaft core of the first damping rotating shaft 21 and the rotating shaft core of the second damping rotating shaft 31.

[0055] In some embodiments, reference Figure 1As shown, the fixing seat of the first damping shaft 21 can be an L-shaped structure, and the fixing seat can include a first fixing section 211 and a second fixing section 212, wherein the first fixing section 211 can be arranged in the first plug-in slot 61 and fixedly connected to the connecting base plate 6; the second fixing section 212 can include a through hole, and the shaft core of the first damping shaft 21 passes through the through hole, and the second fixing section 212 and the edge of the first fixing section 211 are connected and perpendicular to each other; when the angle of the display screen changes, the second fixing section 212 rotates synchronously along the shaft core of the first damping shaft 21.

[0056] Among them, the first fixing section 211 and the second fixing section 212 can be designed as an integral body. The first fixing section 211 is fixedly connected to the connecting base plate 6. Specifically, the two can be connected by screws, such as a pre-set threaded hole on the first fixing section 211, and a threaded hole is also provided at a corresponding position on the connecting base plate 6. The first fixing section 211 is fixed to the connecting base plate 6 by screws passing through these holes. In addition, the first fixing section 211 can also be connected to the connecting base plate 6 by snap-fitting, such as a snap-fit structure that matches the slot on the connecting base plate 6 can be provided on the outer wall of the first fixing section 211. The snap-fits are engaged with each other by pressing or rotating to achieve a quick and stable connection. Of course, the first fixing section 211 and the connecting base plate 6 can also be connected by other suitable methods such as welding, mortise and tenon structure, etc. In addition, the structure of the fixing seat of the second damping shaft 31 is basically the same as that of the fixing seat of the first damping shaft 21. The structure of the fixing seat of the second damping shaft 31 will not be elaborated in detail here.

[0057] refer to Figure 1 As shown, in some embodiments, the connecting base plate 6 may further include a protective groove 63, which may be disposed between the first insertion groove 61 and the second insertion groove 62 and configured to engage with the hinge connecting section 12 to protect and shield the external wiring of the display screen. Specifically, the protective groove 63 may be integrally designed with the first insertion groove 61 and the second insertion groove 62.

[0058] refer to Figure 1 As shown, in some embodiments, the first connecting piece 22 can be an L-shaped structure, and the first connecting piece 22 can include a first connecting segment 221 and a second connecting segment 222, wherein the first connecting segment 221 can be fixedly connected to the shaft core of the first damping shaft 21; the second connecting segment 222 can be fixedly connected to the outer wall of the shaft base 1, and the extension direction of the second connecting segment 222 is perpendicular to the extension direction of the shaft base 1.

[0059] The first connecting section 221 and the second connecting section 222 can be designed as an integral unit. The second connecting section 222 is fixedly connected to the shaft base 1. Specifically, the two can be connected by screws. For example, threaded holes can be pre-set on the second connecting section 222, and threaded holes can also be set at corresponding positions on the shaft base 1. The second connecting section 222 can be fixed to the shaft base 1 by screws passing through these holes. In addition, the second connecting section 222 can also be connected to the shaft base 1 by snap-fitting. For example, a snap-fit structure that matches the slot on the shaft base 1 can be set on the outer wall of the second connecting section 222. The snap-fit structure can be engaged with each other by pressing or rotating to achieve a quick and stable connection.

The stable connection of the display screen 7 with the fixing seat of the first damping shaft 21 and the fixing seat of the second damping shaft 31 ensures that the display screen 7 remains stable and does not shake during operation of the sterilizing machine, thereby improving operational stability and user viewing experience. Furthermore, the damping shaft design makes the rotation of the display screen 7 smooth and controllable, allowing users to easily adjust the angle of the display screen 7 according to actual needs, without difficulty due to excessive resistance or loss of control due to rapid rotation due to insufficient resistance, ensuring that each adjustment is precise. Furthermore, the corresponding arrangement of the wire holes 13 in the support device for the display screen 7 and the through holes of the display screen reduces cable exposure and avoids clutter, while improving the aesthetics and safety of the device and reducing maintenance requirements caused by cable problems.

[0063] In addition, the main unit 8 and the shaft base 1 can be fixedly connected by bolts. Specifically, threaded holes can be provided on the support section 11 of the shaft base 1, and threaded holes can also be provided at corresponding positions on the main unit 8. Bolts are passed through the threaded holes on the shaft base 1 and the main unit 8 and fixed with nuts to achieve a tight connection between the two.
