Description

Technical Field

[0001] This utility model relates to a screen flipping structure and belongs to the field of robotics technology. Background Technology

[0002] In the field of robotics, the screen, as a core component of human-computer interaction, needs to have a flipping function to adapt to the usage needs of different heights and different operating scenarios, such as a 30° screen tilt angle for standing operation and a 15° tilt angle for sitting operation. Existing technologies have the following prominent shortcomings, which restrict the lightweight design and ease of use of robots:

[0003] For example, a screen flipping device with authorization announcement number CN220076279U uses a combination of multiple components such as a support plate, a fixed frame, a linear mechanism, and a hinge assembly. The linear mechanism requires a separate installation space, and the overall structure is large in size, which contradicts the miniaturization requirements of robots and makes the assembly steps cumbersome.

[0004] For example, the robot screen flipping mechanism with authorization announcement number CN221416679U integrates electric components such as motors and damping sleeves, resulting in a high overall weight, accounting for more than 30% of the total weight of the robot head; in addition, it requires additional power lines and control lines, which not only increases the complexity of wiring, but also poses a risk of flipping failure due to motor failure, resulting in high maintenance costs;

[0005] Existing manual flip solutions often lack angle limiting structures, making it easy for the screen to flip angle to exceed 90°, which can lead to screen cable breakage or top cover deformation due to pressure. Furthermore, the damping force is not adjustable, making it prone to wobbling when touched lightly, and easily causing hinge damage when excessive force is applied, resulting in a poor user experience. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a screen flipping structure that achieves the screen stopping at any angle within the range of 0°-90° through the coordinated design of the hinge and the rotating baffle. It has fewer parts, is easy to assemble, occupies less space, is lighter overall, reduces production costs, and has an angle limiting function to avoid damage to components due to excessive flipping.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A screen flip structure includes a frame, a top cover on the top of the frame, a screen embedded in the top of the top cover, and a connector between the screen and the frame, which allows the screen to stop at any angle during rotation.

[0009] Preferably, the connector includes a screen connecting plate and a frame connecting plate, and a hinge with arbitrary stopping is provided between the screen connecting plate and the frame connecting plate.

[0010] Preferably, the screen connecting plate is connected to the screen by bolts, and the frame connecting plate is connected to the frame by bolts.

[0011] Preferably, a shell is mounted on the frame.

[0012] Preferably, a rotating baffle is provided on the movable end of the arbitrarily stopped hinge.

[0013] Preferably, the upper cover has a clearance groove on the side away from the rotating baffle.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] With its simple structure, it effectively improves assembly efficiency, significantly reduces production costs, and is lighter overall than existing electric solutions, thus reducing the load on the robot head and extending the robot's battery life.

[0016] It occupies less structural space, saving space and fitting into the compact space of the service robot's head without requiring additional volume expansion;

[0017] The hinge angle is kept at an accuracy of ±1° to prevent screen shaking from affecting operation. The rotating cover achieves a 90° hard limit, reducing the breakage rate of screen cable and the deformation rate of the top cover.

[0018] The purely mechanical structure has no easily damaged parts such as motors and cables, increasing the service life from 3,000 cycles to 10,000 cycles and reducing maintenance costs. Attached Figure Description

[0025] 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.

[0026] Please see Figures 1-4 This utility model provides a technical solution:

[0027] like Figure 1 As shown, a screen flip structure includes a frame 1, which is made of 6061 aluminum alloy die casting. The roughness of the inner wall of the frame 1 is Ra≤1.6μm to avoid interference with other components. The surface is sprayed with anti-rust paint to adapt to humid environments. A top cover 6 is provided on the top of the frame 1. The top cover 6 is made of PC material and is fixed to the top of the frame 1 by two M3 countersunk screws. The screen 5 is embedded in the top of the top cover 6. The gap between the top cover 6 and the screen 5 is controlled at 0.5-1mm to ensure screen heat dissipation and prevent screen shaking. A connector is provided between the screen 5 and the frame 1, which allows the screen 5 to stop at any angle during rotation.

[0028] Specifically, screen 5 uses a 7-inch industrial touch screen with 4 mounting posts on the back that are precisely aligned with the threaded holes of screen connection plate 2. The screen 5 has a 150mm cable length to ensure that the cable is not pulled when flipped to 90°.

[0029] like Figure 2 As shown, a shell 7 is installed on the frame 1. The shell 7 is made of ABS engineering plastic injection molding and is fixed to the outside of the frame 1 by four M3 self-tapping screws.

[0030] like Figure 4As shown, the connector includes a screen connecting plate 2 and a frame connecting plate 8. A hinge 3 that allows for arbitrary stopping is provided between the screen connecting plate 2 and the frame connecting plate 8. The screen connecting plate 2 is made of Q235 cold-rolled steel plate. One end has four M3 threaded holes, which are fixed to the mounting post on the back of the screen 5 by M3 screws. The other end has two M4 through holes, which are locked to the movable end of the hinge 3 by M4 nuts. The frame connecting plate 8 has the same structure as the screen connecting plate 2. One end is fixed to the threaded hole of the frame 1 by M4 screws, and the other end... The hinge is connected to the fixed end of the hinge 3 to ensure that the perpendicularity between the hinge and the frame is ≤0.5°, avoiding jamming during flipping. The hinge 3 is made of zinc alloy, and the damping force is adjustable, with an adjustment range of 2-5 N·m, which is suitable for screens of different weights from 0.3-1 kg. The rotation angle range is 0-90°. It has a built-in steel ball positioning structure, and the angle maintains an accuracy of ±1°. The hinge volume is only 30mm×20mm×10mm, which reduces the space occupied by 50% compared with traditional hinges. The service life is ≥10,000 flips.

[0031] Furthermore, the screen connecting plate 2 is connected to the screen 5 by bolts, and the frame 1 has a U-shaped opening structure with 4 M4 threaded holes on the top of the opening side for connecting the frame connecting plate 8.

[0032] like Figure 3 As shown, a rotating baffle 4 is provided on the movable end of the free-stop hinge 3. The rotating baffle 4 is made of PP material injection molding and is fixed to the movable end of the free-stop hinge 3 by M3 screws. The rotating baffle 4 is L-shaped. The horizontal section blocks the internal structure of the free-stop hinge 3 to prevent dust from entering. The dust protection level is IP54. The vertical section abuts against the top cover 6 when the screen is flipped to 90° to achieve angle limitation.

[0033] Furthermore, the side of the upper cover 6 away from the rotating baffle 4 has a clearance groove.

[0034] The workflow of this embodiment is as follows: Place the frame 1 flat on the workbench, ensuring the opening faces upwards. Take the outer shell 7, align it with the positioning post of the frame 1, and press it to make the outer shell 7 fit snugly against the frame 1. Use an electric screwdriver to screw four M3 self-tapping screws into the screw holes of the outer shell 7 in sequence, ensuring that the screws do not strip. Take the frame connecting plate 8, align it with the four M4 threaded holes on the top of the frame 1, and pre-tighten two M4 screws. Use a right-angle ruler to check the perpendicularity of the frame connecting plate 8 and the frame 1. If the deviation exceeds the tolerance, adjust the tightness of the screws to calibrate. Align the fixed end of the arbitrarily stopped hinge 3 with the two M4 through holes of the frame connecting plate 8, ensuring that the hinge is not loose. Take the rotating cover plate 4, align it with the M3 threaded hole of the frame connecting plate 8, and secure it with M3 screws. First, ensure that the vertical section of the shield faces the hinge side. Connect the screen connecting plate 2 to the movable end of the hinge 3, insert the M4 screw and tighten it. Manually rotate the connecting plate to test the hinge damping force. Taking a 0.5kg screen as an example, adjust the damping force to 3N·m to ensure that it can be rotated with a light push and does not slide down after releasing. Remove the screen 5, align the back mounting post with the M3 threaded hole of the screen connecting plate 2, and fix it with M3 screws. Avoid overtightening the screws and damaging the screen backlight layer. Organize the screen ribbon cable and arrange it along the ribbon cable groove of the frame 1, ensuring that the ribbon cable is not folded. Remove the top cover 6, align it with the positioning hole of the frame 1, and fix it with two M3 countersunk screws. Check the gap between the top cover and the screen. If the gap is uneven, adjust the tightness of the screws.
