[0044] The invention provides a panel assembly, which is applied to a mobile robot.

[0045] In one embodiment of the present invention, Figure 1 As shown, the mobile robot has a shell, and the panel assembly includes a face shell 1 and a display panel 3. The face shell 1 is detachably arranged on the shell, and a receiving groove 1a is arranged at one end of the face shell 1 close to the shell, and a slope 11 is arranged at one end of the face shell 1 away from the shell. The slope 11 is provided with a display window 11a connected to the receiving groove 1a, and the plane where the slope 11 is located forms an angle with the plane where the connecting surface of the face shell 1 and the shell is located, and the area of ​​the slope 11 is smaller than the opening area of ​​the notch of the receiving groove 1a; the display panel 3 is arranged in the receiving groove 1a and covers the display window 11a.

[0046] In this embodiment, the mobile robot is a robot that can move autonomously and can provide at least one service of navigation, voice conversation, and delivery.

[0047] The panel assembly is used to provide services such as information display and voice dialogue. The face shell 1 of the panel assembly can be detachably connected to the outer shell by means of screw connection, plug connection, snap connection, etc., so that the face shell 1 can be removed from the outer shell or installed on the outer shell. For example, the face shell 1 is provided with a hook, and the outer shell is provided with a slot, and the face shell 1 is detachably connected to the outer shell by the snap connection between the hook and the slot. For another example, the face shell 1 is provided with a convex column, and the outer shell is provided with a concave hole, and the face shell 1 is detachably connected to the outer shell by the plug connection between the convex column and the concave hole. The side of the face shell 1 facing the outer shell is provided with a receiving groove 1a, and the receiving groove 1a can be used to accommodate and assemble the display panel 3 and functional modules such as a camera, a speaker, and a microphone, so that the panel assembly can integrate and realize multiple interactive functions, and the debugging, maintenance and replacement of these functional modules can be realized correspondingly by disassembling the face shell 1. The face shell 1 is separately set on the outer shell of the robot, and is used to install and fix the display panel 3, so that the panel assembly has a display interface that can be used for display interaction, and improves the interactive experience between the user and the robot using the panel assembly. In addition, it also avoids the problem of the robot shell needing to design a protruding structure to install the display panel 3, which brings about the problem of bloated shell structure, which is conducive to saving the volume and material cost of the robot shell. The overall shape of the face shell 1 can be circular, and the cross-section of the face shell 1 can be circular when it is placed flat, so that the face shell 1 can be installed on the robot shell with an overall cylindrical shape and match the shape of the robot shell to enhance the overall aesthetics of the face shell 1 and the shell.

[0048] The inclined surface 11 is a plane disposed at the end of the face shell 1 away from the outer shell, and the plane is arranged at an angle of non-0 degrees and non-180 degrees with the connection surface of the face shell 1 and the outer shell, so that the inclined surface 11 is inclined relative to the connection surface of the face shell 1 and the outer shell. In this way, even when the top surface of the outer shell is designed to be a plane in order to reduce the volume of the outer shell, the display window 11a on the inclined surface 11 can be inclined relative to the top surface of the outer shell by connecting the face shell 1 to the top surface of the outer shell, so that the user of the mobile robot can view the display panel 3 at the display window 11a without looking down, providing the user with a more comfortable viewing angle and improving the user's viewing experience. By designing the area of ​​the inclined surface 11 to be smaller than the opening area of ​​the notch of the accommodating groove 1a of the face shell 1, the area of ​​the connection surface between the face shell 1 and the outer shell of the robot can be increased, and the volume of the end of the face shell 1 away from the outer shell of the robot can be reduced, which is conducive to improving the stability of the connection between the face shell 1 and the outer shell of the robot while reducing the volume of the face shell 1 and reducing the space occupied by the mobile robot. Exemplarily, the entire surface shell 1 can be designed as a truncated cone structure, and the cross-sectional area of ​​the surface shell 1 gradually decreases from one end close to the outer shell to the end far from the outer shell.

[0049] The display panel 3 is used for information display. For example, the display panel 3 can display the main parameter information of the internal system of the mobile robot and provide the user with visual navigation instructions and text dialogue information. The area of ​​the display region of the display panel 3 can be equal to or slightly smaller than the opening area of ​​the display window 11a, so that all the contents displayed by the display panel 3 can be presented to the user through the display window 11a.

[0050] In one embodiment of the present invention, Figure 2 As shown, one end of the face shell 1 away from the inclined surface 11 extends toward the outside of the accommodating groove 1a to form an extension portion 12, and the extension portion 12 surrounds the notch of the accommodating groove 1a; the extension portion 12 is provided with a plurality of installation holes 12a arranged at intervals, and the plurality of installation holes 12a surround the notch of the accommodating groove 1a, and the installation holes 12a are used to realize the installation and fixation of the panel and the outer shell.

[0051] In this embodiment, the extension portion 12 is a part of the face shell 1. The extension portion 12 is extended along the circumference of the outer wall of the face shell 1. The extension portion 12 as a whole can be a non-closed arc structure or a closed ring structure. The extension portion 12 can be integrally formed with the face shell 1. A plurality of mounting holes 12a are provided on the extension portion 12. The plurality of mounting holes 12a can be evenly arranged along the extension portion 12. The face shell 1 and the outer shell can be detachably connected by screws and other locking members passing through the mounting holes 12a and being screwed to the outer shell of the robot. At this time, the extension portion 12 abuts against the outer shell. The design of the extension portion 12 is conducive to increasing the connection surface between the face shell 1 and the outer shell, and improving the connection reliability between the face shell 1 and the outer shell. In addition, because the extension portion 12 protrudes from the periphery of the outer wall of the face shell 1, it is convenient to twist the above-mentioned screws and other locking members, thereby improving the convenience of disassembling and assembling the face shell 1 on the outer shell.

[0052] In one embodiment of the present invention, Figure 3 As shown, the extension portion 12 is provided with a mounting notch 12b, and the mounting notch 12b has a side wall extending circumferentially along the outer wall of the face shell 1, and the side wall is at least partially arranged in an arc segment. The mounting notch 12b is used to realize the installation and fixation of the face shell 1 and the outer shell.

[0053] In this embodiment, Figure 3The direction of the dashed arrow indicates the circumferential direction of the outer wall of the face shell 1, so that the installation notch 12b is designed as a long strip as a whole, and the installation notch 12b extends along the circumference of the outer wall of the face shell 1. On the one hand, the volume of the extension portion 12 can be reduced by the design of the installation notch 12b, saving the material cost of the face shell 1; on the other hand, a limiting protrusion structure matching the installation notch 12b can be provided on the outer shell of the mobile robot, so that when the face shell 1 is installed on the outer shell, the limiting cooperation between the limiting protrusion and the installation notch 12b can improve the reliability of the face shell 1 being installed and fixed on the outer shell. In addition, the installation notch 12b provides conditions for the unique design of the appearance of the face shell 1. The side wall of the installation notch 12b can be designed at least partially as an arc segment structure, such as designing the side wall into an M shape, a wave shape, etc., to achieve a specific design of the outer contour of the face shell 1 and improve the appearance aesthetics of the face shell 1.

[0054] In one embodiment of the present invention, Figure 2 As shown, the extension portion 12 is provided with a mounting groove 12c, and the mounting groove 12c surrounds the slot of the accommodating groove 1a, and the slot of the mounting groove 12c faces the plane where the inclined surface 11 is located, and each mounting hole 12a is provided on the bottom wall of the mounting groove 12c; the mounting groove 12c is defined to have a first slot end 12c1 and a second slot end 12c2, and the mounting groove 12c is formed by the first slot end 12c1 extending toward the second slot end 12c2 along the circumferential direction of the outer wall of the face shell 1, and the mounting notch 12b is located between the first slot end 12c1 and the second slot end 12c2.

[0055] In this embodiment, the mounting groove 12c is a U-shaped structure as a whole. The mounting groove 12c is arranged along the extension portion 12. The first groove end 12c1 and the second groove end 12c2 of the mounting groove 12c are respectively located on opposite sides of the mounting notch 12b. The first groove end 12c1 and the second groove end 12c2 are two end portions in the extension direction of the mounting groove 12c. The first groove end 12c1 and the second groove end 12c2 are respectively the starting end and the ending end of the groove body structure of the mounting groove 12c. Through the design of the groove body structure of the above-mentioned installation groove 12c, on the one hand, the installation notch 12b is arranged along the extension direction of the installation groove 12c as a whole, so that the installation groove 12c can be smoothly transitioned from the first groove end 12c1 to the second groove end 12c2 through the installation notch 12b in the circumferential direction of the outer wall of the face shell 1, and the installation notch 12b becomes a continuation structure in the extension direction of the first groove end 12c1 and the second groove end 12c2, which is beneficial to improving the overall consistency and aesthetics of the appearance of the face shell 1; on the other hand, it can avoid the problem that when the installation groove 12c is designed as an annular groove, the positions of the installation notch 12b and the installation groove 12c are easily interfered with, and the installation notch 12b needs to be arranged on the outer periphery of the annular installation groove 12c, resulting in an increase in the width of the extension portion 12 and the volume of the face shell 1.

[0056] In one embodiment of the present invention, Figure 2As shown, the panel assembly further includes a light emitting member 2, which is accommodated and limited in the mounting groove 12c, and the light emitting member 2 covers each mounting hole 12a.

[0057] In this embodiment, the light-emitting element 2 is used to provide visual light to the user. The light-emitting element 2 can be an active light-emitting structure or a light-guiding structure. For example, the light-emitting element 2 can be an LED light strip that actively emits light, or a light-guiding strip that can conduct light emitted by the internal light source of the mobile robot. The setting of the light-emitting element 2, on the one hand, enables the mobile robot to control the light color, flashing frequency, etc. of the light-emitting element 2 to indicate the current working state of the mobile robot, and realizes richer interactive functions; on the other hand, the light-emitting element 2 can block each mounting hole 12a to prevent each mounting hole 12a from being exposed outside the face shell 1, realize the hidden design of the mounting hole 12a, and improve the aesthetics of the face shell 1. Because the mounting groove 12c surrounds the notch of the accommodating groove 1a and is arranged along the circumference of the outer wall of the face shell 1, the mounting groove 12c can be an arc groove as a whole, and the light-emitting element 2 can be an arc structure as a whole, so that the shape of the light-emitting element 2 can be adapted to the shape of the mounting groove 12c, which is convenient for the light-emitting element 2 to be assembled in the mounting groove 12c, and is also conducive to improving the overall aesthetics of the light-emitting element 2 and the face shell 1 after assembly.

[0058] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the face shell 1 has an outer peripheral wall 13 located between the inclined surface 11 and the extension portion 12, and the outer peripheral wall 13 is provided with a sound hole 13a connected to the accommodating groove 1a; the panel assembly also includes a sound unit 5 arranged in the accommodating groove 1a, and the sound unit 5 is arranged near the sound hole 13a.

[0059] In this embodiment, the sound unit 5 is used to make sounds, and the sound unit 5 includes but is not limited to a speaker. The sound emitted by the sound unit 5 can be transmitted to the user through the sound hole 13a, thereby realizing voice output to the user. The sound unit 5 can be fixed to the bottom wall of the accommodating groove 1a by screwing, snapping, plugging, etc., so that when the face shell 1 is removed from the outer shell, the sound unit 5 is removed from the outer shell together with the face shell 1; when the face shell 1 is installed on the outer shell, the sound unit 5 is also installed on the outer shell together with the face shell 1; the sound unit 5 and the face shell 1 form a modular structure that can be disassembled and assembled at the same time, so that the debugging, maintenance and replacement of the sound unit 5 can be achieved by disassembling the face shell 1.

[0060] The peripheral wall 13 of the face shell 1 may be an arc surface or the cross-sectional shape of the peripheral wall 13 may be a polygon. When the peripheral wall 13 is an arc surface, the peripheral wall 13 of the face shell 1 is smooth without edges or corners, which is helpful to reduce or even avoid the risk of scratches when the user touches the face shell 1. The peripheral wall 13 of the face shell 1 may be provided with one or more sound holes 13a, and one or more sound units 5 may be configured corresponding to the sound holes 13a to achieve multi-channel audio output, enhance the stereoscopic effect of sound propagation, and enhance the user's voice interaction experience.

[0061] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the inclined surface 11 is provided with a limiting hole 11b and a sound pickup hole 11c which are connected to the accommodating groove 1a; the display window 11a is located between the limiting hole 11b and the sound pickup hole 11c, and the minimum distance between the center of the limiting hole 11b and the outer shell is greater than the minimum distance between the center of the sound pickup hole 11c and the outer shell; the panel assembly also includes a camera unit 6 and a sound pickup unit 7, the camera unit 6 is at least partially accommodated and limited in the limiting hole 11b, and the sound pickup unit 7 is arranged in the accommodating groove 1a and close to the sound pickup hole 11c.

[0062] In this embodiment, the limiting hole 11b is used to accommodate and limit at least part of the camera unit 6. The size and shape of the limiting hole 11b are adapted to the size and shape of the camera unit 6. A step structure can be provided in the limiting hole 11b to cooperate with the step structure on the camera to limit the camera more reliably in the limiting hole 11b. The camera unit 6 includes but is not limited to being a camera. The camera unit 6 may also include a lens assembly, and a plurality of optical films for dimming and focusing are provided in the lens assembly to improve the clarity of the image captured by the camera unit 6.

[0063] The sound pickup hole 11c is used for the sound pickup unit 7 to collect sound. The sound pickup unit 7 can be fixed to the bottom wall of the accommodating groove 1a by means of screw connection, clamping connection, etc. The sound pickup unit 7 can cover the sound pickup hole 11c so that the sound pickup unit 7 is located in the axial direction of the sound pickup hole 11c, which is more conducive to the sound pickup unit 7 to accurately collect the user's voice. The sound pickup unit 7 includes but is not limited to a microphone and a sound collector. One or more sound pickup holes 11c can be set on the inclined surface 11, and one or more sound pickup units 7 can be configured corresponding to the sound hole 13a to achieve multi-directional sound pickup, so that when the user stands in multiple directions beside the mobile robot, the user's voice can be collected directly by different sound pickup units 7, thereby improving the spatial range and collection accuracy of the user's voice collection, thereby improving the user's voice interaction experience.

[0064] In this embodiment, the limiting hole 11b is located at the top of the inclined surface 11, and the sound pickup hole 11c is located at the bottom of the inclined surface 11. The minimum distance between the center of the limiting hole 11b and the housing is greater than the minimum distance between the center of the sound pickup hole 11c and the housing. At this time, the camera unit 6 is located above the display window 11a. When the user views the display panel 3 exposed at the display window 11a, the camera unit 6 can aim at the user's face to identify the user, while the sound pickup hole 11c is located closer to the user's mouth, which is conducive to reducing the attenuation of the user's voice in the process of propagating to the sound pickup hole 11c through the air medium, and improving the accuracy of the sound pickup hole 11c picking up the user's voice.

[0065] The face shell 1 includes a three-section mounting structure including an extension portion 12, an outer peripheral wall 13 and an inclined surface 11, wherein the extension portion 12 is provided with a mounting groove 12c, the outer peripheral wall 13 is provided with a sound hole 13a, the inclined surface 11 is provided with a limiting hole 11b and a sound pickup hole 11c, the light-emitting component 2 is installed and fixed in the mounting groove 12c, the sound-emitting unit 5 is located in the accommodating groove 1a, and can be installed and fixed on the periphery of the sound hole 13a; the sound pickup unit 7 is located in the accommodating groove 1a, and can be installed and fixed on the periphery of the sound pickup hole 11c; the camera unit 7 is installed and fixed in the limiting hole 11b. In this way, the light-emitting component 2, the sound-emitting unit 5, the camera unit 6 and the sound pickup unit 7 can be arranged in layers in space through the above-mentioned three-stage installation structure. The structural design of the layered arrangement can avoid mutual interference between the installation positions of the light-emitting component 2, the sound-emitting unit 5, the camera unit 6 and the sound pickup unit 7, thereby reducing the arrangement spacing between the light-emitting component 2, the sound-emitting unit 5, the camera unit 6 and the sound pickup unit 7 as much as possible, and further limiting the lateral width of the face shell 1 as much as possible. In this way, it is possible to realize the integrated design of multiple interactive functional modules on the face shell 1 while maximally reducing the volume of the face shell 1, thereby reducing the space occupancy of the panel assembly and the mobile robot using the panel assembly.
