Technical Field

[0001] The utility model relates to the technical field of interactive robots, in particular to a robot head. Background Art

[0002] With the rapid development of intelligent robotics, robots are playing an increasingly important role in human-machine interaction. This is particularly true in areas such as service robots and educational robots. The design of a robot's head directly impacts the efficiency and interactivity of its interactions with humans. Currently, most robot heads on the market have relatively simple designs, limited functionality, and a general lack of touch interaction. This makes it difficult for users to interact directly with the robot through a touchscreen, limiting the application scenarios of robots as interactive tools. Furthermore, most robots require the robot's body to drive their head in order to rotate, meaning the robot's entire body must rotate in order for the head to rotate. This results in a limited degree of design freedom for the robot's head. Utility Model Content

DETAILED DESCRIPTION

[0033] The following describes the implementation of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific implementations, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined unless they conflict.

[0034] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0035] like Figures 1 to 3As shown, a robot head includes a housing 6, wherein a working component is disposed within the housing 6, wherein a touch screen 12 is disposed on one side of the housing 6, and a lower portion of the housing 6 is connected to an angle adjustment mechanism, wherein the degree of freedom adjustment mechanism includes a first degree of freedom adjustment component and a second degree of freedom adjustment component;

[0036] The first degree of freedom adjustment component can adjust the Yaw angle of the housing 6;

[0037] The second degree of freedom adjustment component can adjust the pitch angle of the housing 6 .

[0038] The purpose of this design is to enable the entire robot head to rotate horizontally and vertically by installing a first degree of freedom adjustment component and a second degree of freedom adjustment component. This allows the head to flexibly adjust its orientation, providing a more natural interactive experience. The minimized neck size also makes the entire head and neck more aesthetically pleasing. The addition of a touchscreen allows users to interact with the robot through direct touch, expanding the robot's applications in education, service, and other fields.

[0039] In this embodiment, the first degree of freedom adjustment component includes a base 1, a Yaw motor 2 and a Yaw-Pitch motor connector 3;

[0040] The lower part of the base 1 is connected to the robot pole;

[0041] The Yaw motor 2 is arranged on the upper part of the base 1;

[0042] The Yaw-Pitch motor connector 3 is arranged on the upper part of the Yaw motor 2 and is connected to the power output end of the Yaw motor 2 and can rotate in the horizontal direction.

[0043] The second degree of freedom adjustment component includes a pitch motor 4 and a head and neck connection member 5;

[0044] The pitch motor 4 is provided on the yaw-pitch motor connector 3;

[0045] One end of the head and neck connector 5 is connected to the power output end of the pitch motor 4, and the other end of the head and neck connector 5 is connected to the bottom of the housing 6. The head and neck connector 5 can rotate in the vertical direction.

[0046] It should be pointed out that Yaw in this embodiment refers to yaw, which is usually adjusted by rotation in the horizontal direction, while Pitch refers to pitch, which is usually adjusted by rotation in the vertical direction. The neck gimbal device achieves two-degree-of-freedom movement by driving the Pitch motor with the Yaw motor, and can flexibly adjust the angle of the head to adapt to observation and interaction needs in different directions; the connection keys between the motors and with other structures are designed to be as light and simple as possible, thereby minimizing the size and weight of the neck.

[0047] In this embodiment, a head-neck connector fixing hole 21 is provided at the bottom of the housing 6 , and the housing 6 is detachably connected to the head-neck connector 5 via a bolt passing through the head-neck connector fixing hole 21 .

[0048] At the same time, in this embodiment, a depth camera 7 and a wide-angle camera 8 are provided in the housing 6, and the depth camera 7 and the wide-angle camera 8 are located on the same surface as the touch screen 12, and a camera gasket groove 14 is provided on the housing 6, and the camera gasket groove 14 is filled with a depth camera gasket 9, one end of the depth camera gasket 9 is in contact with the depth camera 7, and the depth camera gasket 9 makes the depth camera 7 and the wide-angle camera 8 at the same horizontal height, and a depth camera fixing hole 15 and a wide-angle camera screw column 17 are provided in the housing 6, and the depth camera 7 is fixed by a bolt passing through the depth camera fixing hole 15, and the wide-angle camera 8 is fixed by a bolt inserted into the wide-angle camera screw column 17.

[0049] The purpose of this design is that the head device integrates a depth camera and a wide-angle camera. The depth camera is fixed to the outer shell through a gasket and ensures that it is at the same level as the wide-angle camera, thereby improving the robot's visual perception ability and supporting the capture of depth information and panoramic view of the environment. Through the integration of the depth camera and the wide-angle camera, the robot can perceive depth and wide-angle information in more complex environments, thereby enhancing its perception of the environment.

[0050] It should also be pointed out that the wide-angle camera screw column is used to fix the wide-angle camera and ensure that its lens extends beyond the housing to just be able to capture a full 180° range, and the thickness of the gasket is just enough to ensure that the depth camera and the wide-angle camera are at the same level.

[0051] In this embodiment, Figure 4 and Figure 5 As shown, the housing 6 is provided with a touch screen groove, a screen pressure fixing plate screw column 16 and a screen pressure fixing plate screw hole 22, and the interactive end of the touch screen 12 is placed in the touch screen groove, and a screen pressure fixing plate 13 is provided on the back of the touch screen 12;

[0052] The screen pressure fixing plate screw hole 22 is located at the bottom of the housing 6;

[0053] The screen pressure fixing plate 13 is fixed by the screen pressure fixing plate screw column 16 and the screen pressure fixing plate screw hole 22 .

[0054] The purpose of this design is to integrate a touchscreen on the front of the head, allowing users to interact directly with the robot through the screen. The touchscreen is fixed using a combination of fixed positions and foam board extrusion to ensure screen stability and heat dissipation. No glue is used, making assembly and disassembly simple. The addition of the touchscreen allows users to interact with the robot through direct touch, expanding the robot's applications in education, service, and other fields. The mounting structure also makes assembly and disassembly of the screen relatively simple, and the addition of foam further improves the screen's stability while preventing damage caused by pressure.

[0055] It's worth noting that the housing includes a first protruding groove 24, a second protruding groove 25, and a third protruding groove 26. These grooves 24, 25, and 26 all serve to position the screen. The first protruding groove 24 is used for both screen and speaker cables, while the second protruding groove 25 is only for speaker cables. The three holes on the front side of the housing ensure that the two camera lenses and the touchscreen portion of the screen are exposed. Furthermore, the array of straight notches on the screen pressure plate 13 also serves to dissipate heat from the screen.

[0056] In this embodiment, a head wire hole 20 is provided at the bottom of the shell 6, and the data cable extends into the shell 6 from the head wire hole 20 and is connected with the working part. Speakers 11 and speaker fixings 10 are provided on both sides of the shell 6, and the speaker 6 is connected to the shell 6 through the speaker fixings 10.

[0057] Furthermore, if Figure 6 As shown, a back cover fixing hole 23 is provided at the bottom of the housing for fixing the back cover. It should be noted that in order to minimize weight, the back cover is made of ABS plastic, so all threaded holes that need to be tapped must be replaced with embedded round nuts. The back cover is connected to the side of the housing through a circle of raised structures along the outer circumference. The two breaks in the raised structure are to prevent interference with the speaker. The four screw posts in the middle are used to fix the screen circuit board, and a heat dissipation hole is drilled in the center of the cover to prevent the temperature inside the head from being too high. The heat dissipation holes are designed in the back cover to ensure temperature control of internal components and structural stability. The head design takes heat dissipation performance into consideration to avoid component failure caused by high temperature and improve the stability and service life of the system.

[0058] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
