[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, a display screen structure 10 is provided, including a screen assembly 100, a first driving assembly 200, a second driving assembly 300, a mounting body 400, and a controller (not shown). The first driving assembly 200 is driveably connected to the screen assembly 100 and is used to drive the screen assembly 100 to rotate about a first axis. The second driving assembly 300 is driveably connected to the first driving assembly 200 and is used to drive the screen assembly 100 to rotate about a second axis via the first driving assembly 200. The mounting body 400 is connected to the second driving assembly 300. The controller is communicatively connected to both the first driving assembly 200 and the second driving assembly 300. The first axis and the second axis extend in different directions.

[0036] In the above embodiment, when the display screen structure 10 is in use, the controller controls the first driving component 20 to drive the screen component 100 to rotate around the first axis, and at the same time controls the second driving component 300 to drive the first driving component 200 and the screen component 100 to rotate around the second axis, so that the tilt angle and orientation of the screen component 100 can be adjusted to accommodate users of different heights and positions to observe and operate the screen component 100, thereby improving the flexibility and practicality of the display screen structure 10.

[0037] like Figure 1 and Figure 2 As shown, optionally, the display structure 10 also includes a first detection element 500 communicatively connected to a controller. The first detection element 500 is mounted on the mounting body 400 and is used to detect the user's face position. Thus, when the display structure 10 is in use, the first detection element 500 identifies the user's face position and feeds it back to the controller. The controller generates an adjustment signal based on the face position and the position of the screen assembly 100, and sends the adjustment signal to the first drive assembly 200 and the second drive assembly 300. The first drive assembly 200 drives the screen assembly 100 to rotate around a first axis according to the adjustment signal, and the second drive assembly 300 drives the first drive assembly 200 and the screen assembly 100 to rotate around a second axis according to the adjustment signal. This makes the tilt angle and orientation of the screen assembly 100 adjustable to accommodate users of different heights and positions who want to observe and operate the screen assembly 100. At the same time, the screen assembly 100 can also automatically follow the user's adjustment to ensure that the screen assembly 100 is always facing the user's face position, improving the flexibility and practicality of the display structure 10.

[0038] It should be noted that the first detection element 500 is used to detect the user's face position. The first detection element 500 can directly detect the user's face position, or it can indirectly detect the user's face position by detecting the user's height or body parts.

[0039] It should be noted that the fact that the first axis and the second axis extend in different directions means that, in spatial geometry, the first axis and the second axis intersect or are skewed.

[0040] The first detection element 500 can be configured as a fisheye camera, infrared sensor, or other detection structure capable of detecting the position of a face. The first detection element 500 can be mounted on the mounting body 400 by snap-fit, plug-in, screw-in, or other methods. The number of first detection elements 500 can be flexibly adjusted according to actual usage needs. The controller can use existing algorithms or calculation formulas to automatically generate adjustment signals based on the face position and the position of the screen component 100. The controller can be configured as a control panel, programmable logic controller, or other control structure. The controller can communicate with the first driving component 200, the second driving component 300, and the first detection element 500 via data cables, power lines, Bluetooth, wireless network communication technology, or other methods.

[0041] The extension directions of the first axis and the second axis can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, the second axis extends vertically, and the extension direction of the first axis is perpendicular to the extension direction of the second axis, thereby enabling the screen assembly 100 to achieve pitch and yaw motion.

[0042] like Figure 1 and Figure 3 As shown, optionally, the display structure 10 also includes a gimbal assembly 600. A second drive assembly 300 is connected to the gimbal assembly 600. A first drive assembly 200 is mounted on the gimbal assembly 600. Thus, the gimbal assembly 600 can act as a shock absorber, increasing the stability of the screen assembly 100 during adjustment, thereby improving the practicality and user experience of the display structure 10.

[0043] The gimbal assembly 600 can employ any existing gimbal structure capable of damping the screen assembly 100. In other embodiments, the second drive assembly 300 can also be connected to the first drive assembly 200 via a mounting base, mounting bracket, mounting plate, or other structure.

[0044] In other embodiments, the display structure 10 further includes a translation mechanism mounted on the gimbal assembly 600. The translation mechanism is drively connected to the first drive assembly 200 and is used to drive the screen assembly 100 to translate via the first drive assembly 200. This increases the adjustment range of the screen assembly 100, improving the practicality of the display structure 10.

[0045] like Figure 1 and Figure 3As shown, in one embodiment, the gimbal assembly 600 includes a gimbal bracket 610 fixed to the mounting body 400 and a gimbal housing 620 located on the side of the gimbal bracket 610 away from the mounting body 400. The gimbal bracket 610 is provided with a mounting through hole 611. The second drive assembly 300 includes a rotating shaft 310 and a first drive member 320 mounted on the mounting body 400. One end of the rotating shaft 310 is driveably connected to the first drive member 320, and the other end passes through the mounting through hole 611 and is driveably connected to the gimbal housing 620. The rotating shaft 310 is limited in fit with the inner sidewall of the mounting through hole 611. The first drive assembly 200 is mounted on the gimbal housing 620. In this way, the gimbal bracket 610 can provide radial limiting for the rotating shaft 310, ensuring that the first drive member 320 can stably and reliably drive the gimbal housing 620 and the screen assembly 100 to rotate around the second axis through the rotating shaft 310, thereby improving the reliability of the display screen structure 10.

[0046] The gimbal bracket 610 can be mounted on the mounting body 400 by snap-fit, plug-in, screw-in, or other fixing methods. The first drive component 320 can be configured as a rotary motor, rotary cylinder, or other drive structure. The first drive component 320 can be mounted on the mounting body 400 by snap-fit, plug-in, screw-in, or other fixing methods. One end of the rotating shaft 310 can be connected to the first drive component 320 by snap-fit, screw-in, plug-in, or other methods. The other end of the rotating shaft 310 can be connected to the gimbal housing 620 by snap-fit, screw-in, plug-in, or other methods, or it can be connected to the gimbal housing 620 by means of an intermediate component.

[0047] like Figure 3 As shown, the second drive assembly 300 further includes a limit bearing 330, which is sleeved on the outer side wall of the rotating shaft 310 and fixed in the mounting through hole 611.

[0048] The number of limiting bearings 330 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, each limiting bearing 330 includes an inner ring and an outer ring. The inner ring is fitted onto the rotating shaft 310 and radially limits its movement along the shaft. The outer ring is fixed to the inner wall of the mounting through hole 611. The limiting bearings 330 are configured as angular contact ball bearings, with two bearings installed from both ends of the mounting through hole 611.

[0049] like Figure 3As shown, optionally, the end of the rotating shaft 310 away from the first driving member 320 is provided with an external thread. The second driving assembly 300 also includes a locking nut 340 threadedly connected to the external thread and a first adapter 350 with a connecting hole. The rotating shaft 310 passes through the connecting hole. The first adapter 350 is fixedly connected to the gimbal housing 620 and is located between the locking nut 340 and the limiting bearing 330, so that the locking nut 340 can cooperate with the limiting bearing 330 to fix the first adapter 350 to the rotating shaft 310. In this way, the first adapter 350 is locked and fixed by the cooperation of the limiting bearing 330 and the locking nut 340, improving the convenience of assembling the display screen structure 10. Furthermore, the first adapter 350 is fixedly connected to the gimbal housing 620, so that when the rotating shaft 310 rotates, the force of the rotating shaft 310 can be better transmitted to the gimbal housing 620 through the first adapter 350, making the entire structure more evenly stressed and stable. At the same time, because the force transmission is more reasonable, unnecessary stress and wear on the rotating shaft 310 during rotation are reduced, which helps to improve the service life of the rotating shaft 310.

[0050] It should be noted that the locking nut 340 engages with the inner ring of the limit bearing 330 to fix the first adapter 350 onto the rotating shaft 310.

[0051] The first adapter 350 can be configured as an adapter plate, adapter base, adapter platform or other adapter structure, and the area of ​​the first adapter 350 can be reasonably set as needed to ensure that there is enough contact area with the gimbal housing 620 to achieve a stable connection, and to prevent shaking or loosening due to poor connection during use, which would affect the stability of the display screen structure 10.

[0052] like Figure 1 , Figure 4 and Figure 5 As shown, in one embodiment, the first drive assembly 200 includes a second drive member 210 with an output shaft and a second adapter 220 fixed to the output shaft. The second drive member 210 is mounted on the gimbal assembly 600. The axis of the output shaft coincides with the first axis. The second adapter 220 is fixedly connected to the screen assembly 100. Thus, the second drive member 210 is connected to the screen assembly 100 via the second adapter 220, improving the ease of assembly of the display screen structure 10.

[0053] The second drive component 210 can be configured as a rotary motor, rotary cylinder, or other drive structure. The second drive component 210 can be mounted on the pan-tilt assembly 600 by snap-fit, plug-in, screw connection, or other means. The second adapter component 220 can be fixed to the output shaft by snap-fit, plug-in, screw connection, or other means. The second adapter component 220 can be fixedly connected to the screen assembly 100 by snap-fit, plug-in, screw connection, or other means. The second adapter component 220 can be configured as an adapter sleeve, adapter base, adapter connector, or other adapter structure.

[0054] like Figure 4 , Figure 5 and Figure 6 As shown, optionally, the display screen structure 10 also includes a rotating assembly 700. The rotating assembly 700 is connected to both the pan-tilt assembly 600 and the screen assembly 100, so that the screen assembly 100 can rotate relative to the pan-tilt assembly 600 about a first axis via the rotating assembly 700. In this way, the rotating assembly 700 can play a guiding and limiting role, ensuring that the screen assembly 100 can rotate stably and reliably about the first axis, thereby improving the reliability of the display screen structure 10.

[0055] The rotating component 700 can be configured as any existing structure for rotatably connecting two objects; for example, the rotating component 700 can be a shaft or a bearing, and the gimbal assembly 600 and the screen assembly 100 are rotatably connected via the shaft or bearing. Specifically, in this embodiment, the rotating component 700 and the first drive assembly 200 are arranged along the extension direction of the first axis and are respectively connected to the opposite sides of the screen assembly 100.

[0056] like Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, in one embodiment, the mounting body 400 includes a mounting housing 410 with a first cable pass-through hole. A controller is located within the mounting housing 410. The gimbal assembly 600 includes a gimbal housing 620, which has a second cable pass-through hole 621 corresponding to the first cable pass-through hole. The screen assembly 100 includes a screen housing 110 and a display screen 120 mounted on the screen housing 110. The rotating assembly 700 includes a sliding bearing 710, which communicates with both the gimbal housing 620 and the screen housing 110 to form a third cable pass-through hole 711. The display screen structure 10 also includes a connecting cable, one end of which is connected to the controller, and the other end passes through the first cable pass-through hole, the second cable pass-through hole 621, and the third cable pass-through hole 711 and is connected to the display screen 120. Thus, the connecting lines for connecting the controller to the first drive component 200 and the connecting lines for connecting the controller to the display screen 120 are all hidden, ensuring that the gimbal housing 620 will not interfere with the connecting lines during the rotation of the second axis and the screen housing 110 will not interfere with the connecting lines during the rotation of the first axis, thereby improving the reliability of the display screen structure 10.

[0057] like Figure 5 and Figure 6 As shown, specifically in this embodiment, the gimbal housing 620 is provided with a first limiting bone 622, and the screen housing 110 is provided with a second limiting bone 111. The first limiting bone 622 and the second limiting bone 110 are spaced apart and are respectively used to limit the two end faces of the sliding bearing 710. The first limiting bone 622, the second limiting bone 111, the gimbal housing 620, and the screen housing 110 form an installation space, and the sliding bearing 710 is installed in the installation space. The rotating assembly 700 also includes a bearing cover 720 and fastening bolts. The fastening bolts are used to fasten the bearing cover 720 to the screen housing 110 together, at which time the screen housing 110 can rotate around the first axis.

[0058] like Figure 3 As shown, in one embodiment, the display structure 10 further includes a second detection element 800 communicatively connected to a controller. The second detection element 800 is mounted on the screen assembly 100 and is used to detect the position of a target object. Thus, while the first driving assembly 200 and the second driving assembly 300 drive the screen assembly 100 to rotate, the second detection element 800 also rotates synchronously with the screen assembly 100, increasing the detection range of the second detection element 800 and ensuring that the second detection element 800 can detect the position of the target object, thereby improving the practicality of the display structure 10.

[0059] The second detection element 800 can be configured as an RGBD camera, fisheye camera, infrared sensor, or other structure capable of detecting the position of a target object. The number and installation position of the second detection element 800 can be flexibly adjusted according to actual usage needs. Specifically, in this embodiment, the second detection element 800 can be installed on the screen housing 110 by snap-fit, plug-in, screw-in, or other means, and is located below the display screen 120.

[0060] like Figure 7 As shown, in one embodiment, a robot 1 is provided, including a robot body 20 and a display screen structure 10 as described in any of the above embodiments, with a mounting body 400 mounted on the robot body 20.

[0061] In the robot 1 described above, when in use, the first detection element 500 identifies the user's face position and feeds it back to the controller. The controller generates an adjustment signal based on the face position and the position of the screen component 100, and sends the adjustment signal to the first drive component 200 and the second drive component 300. The first drive component 200 drives the screen component 100 to rotate around the first axis according to the adjustment signal, and the second drive component 300 drives the first drive component 200 and the screen component 100 to rotate around the second axis according to the adjustment signal. This makes the tilt angle and orientation of the screen component 100 adjustable to accommodate users of different heights and positions who observe and operate the screen component 100. At the same time, the screen component 100 can also automatically follow the user to adjust, ensuring that the screen component 100 is always facing the user's face position, thus improving the flexibility and practicality of the robot 1.

[0062] The robot body 20 can be any existing robot body without a display screen 120. The robot 1 in this application can be a delivery robot or a cleaning robot, etc. The mounting body 400 can be mounted to the robot body 20 by snap-fit, plug-in, screw-in, or other means. In other embodiments, the mounting body 400 can also be part of the robot body 20.

[0063] Specifically, in this embodiment, the following detailed description will be based on the example of robot 1 automatically riding an elevator, with the elevator's control panel as the target object. Robot 1 also includes a robotic arm mounted on the mounting body 400, which is communicatively connected to the controller. When robot 1 enters the elevator's touch-sensitive area, the gimbal assembly 600 automatically adjusts so that the second detection element 800 is at an angle that allows it to observe the elevator's control panel. The second detection element 800 feeds back the control panel's position information to the controller, which then controls the robotic arm to perform button operations based on the feedback position information, thereby improving the practicality of robot 1.

[0064] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0065] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0066] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0067] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0068] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element.
