For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0021] To solve the problem of inflexible movement of the robot head in the prior art, the present utility model provides a head assembly for a robot. The head assembly 100 of the present utility model includes: a first steering device 20, the first steering device 20 includes a first drive seat 21 and a first bracket 22 rotatably connected to the first drive seat 21, and the first drive seat 21 can drive the first bracket 22 to rotate around a first rotation axis; and a second steering device 30, the second steering device 30 includes a second drive seat 31 and a second bracket 32 rotatably connected to the second drive seat 31, the second drive seat 31 can drive the second bracket 32 to rotate around a second rotation axis and the second drive seat 31 is fixedly connected to the first bracket 22, and the first rotation axis and the second rotation axis are perpendicular to each other.

[0022] Figure 1 FIG. is an exploded view of an embodiment of the head assembly for a robot of the present utility model. In one or more embodiments, the head assembly 100 of the present utility model includes a housing 10 and a plurality of components disposed inside the housing 10, and these components include but are not limited to a first steering device 20, a second steering device 30, a display unit 40, a sound unit 50, a sensing unit 60, etc. Alternatively, the display unit 40, the sound unit 50, or the sensing unit 60 may also be omitted.

[0023] Continue to refer to Figure 1 , in one or more embodiments, the housing 10 includes a first housing 11 and a second housing 12 detachably connected to the first housing 11. When the first housing 11 and the second housing 12 are fixed together, the shape of the housing 10 is generally spherical to mimic a human head. An opening 111 is provided on the first housing 11 for displaying the components inside the head assembly 100 to the outside or for signal transmission, etc. Alternatively, the housing 10 may also be configured into other suitable structures according to actual needs.

[0024] Figure 2 FIG. is a schematic internal structure diagram of an embodiment of the head assembly for a robot of the present utility model. In one or more embodiments, the head assembly 100 includes a neck fixing seat 70, and the first steering device 20 and the second steering device 30 are disposed on the neck fixing seat 70. Based on Figure 2 the shown orientation, the neck fixing seat 70 is disposed at the lowermost part inside the head assembly 100 for connecting to the limb of the robot. Alternatively, the neck fixing seat 70 may also be omitted.

[0025] Continue to refer to Figure 1 and Figure 2 , in one or more embodiments, the first steering device 20 includes a first drive seat 21 and a first bracket 22 rotatably connected to the first drive seat 21. The first drive seat 21 can drive the first bracket 22 to rotate around the first rotation axis. Based onFigure 2 In the orientation shown, the first bracket 22 can rotate counterclockwise about a first rotation axis perpendicular to the paper plane. Correspondingly, when the first bracket 22 rotates counterclockwise by a predetermined angle, it can then rotate back clockwise about the first rotation axis Figure 2 to the position shown. In one or more embodiments, the first bracket 22 includes a limiting portion 221. When the first bracket 22 rotates counterclockwise by a predetermined angle from Figure 2 the position shown, the limiting portion 221 abuts against the first driving seat 21 or the neck fixing seat 70 to limit the rotation of the first bracket 22 and prevent the first steering device 20 from being damaged due to excessive skewing of the center of gravity of the head assembly 100. Alternatively, the setting of the limiting portion 221 can also be cancelled according to actual needs.

[0026] Continue to refer to Figure 1 and Figure 2 , in one or more embodiments, the second steering device 30 includes a second driving seat 31 and a second bracket 32 rotatably connected to the second driving seat 31. The second driving seat 31 is fixedly connected to the first bracket 22. Driven by the first driving seat 21, the second driving seat 31 rotates synchronously with the first bracket 22. Alternatively, the assembly relationship between the first steering device 20 and the second steering device 30 can also be interchanged, that is, the second driving seat is connected to the neck fixing seat 70, and the first driving seat is arranged on the second bracket 32. In one or more embodiments, the second driving seat 31 can drive the second bracket 32 to rotate about a second rotation axis. Based on Figure 2 the orientation shown, the second rotation axis extends in the up-down direction and is perpendicular to the first rotation axis, so as to enable the head assembly 100 to rotate in two mutually orthogonal directions. Therefore, when the first driving seat 21 drives the first bracket 22 to rotate about the first rotation axis, the head assembly 100 can perform the actions of nodding or raising the head. When the second driving seat 31 drives the second bracket 32 to rotate about the second rotation axis, the head assembly 100 can perform the action of turning left and right.

[0027] Continue to refer to Figure 2 , in one or more embodiments, the second bracket 32 includes opposite first side 321 and second side 322. The first housing 11 and the display unit 40 are both arranged on the first side 321 so that the user can see the information displayed on the display unit 40 through the opening 111. The display unit 40 includes a third bracket 41 and a display screen 42 arranged on the third bracket 41. The display screen 42 is a flexible display screen and at least part of it is configured to be curved to imitate the human facial contour and make the appearance more realistic. A human face image or a human-machine interaction instruction, etc. can be displayed on the display screen 42. Alternatively, the display unit 40 can also be arranged at other suitable positions of the head assembly 100.

[0028] Continue to refer to Figure 2, in one or more embodiments, the speaker unit 50 and the second housing 12 are disposed on the second side 322. Sound holes may be provided on the second housing 12 so that the sound signal of the speaker unit 50 can be transmitted to the user more clearly. Alternatively, the speaker unit 50 may also be disposed at other suitable positions of the head assembly 100. In one or more embodiments, the speaker unit 50 includes a fourth bracket 51 and a speaker 52 fixed to the fourth bracket 51. The fourth bracket 51 forms a fixed connection with the second bracket 32. Alternatively, the speaker unit 50 may also be configured into other suitable structures.

[0029] Continuing to refer Figure 2 , in one or more embodiments, the sensing unit 60 is disposed on the side of the second bracket 32 opposite to the second drive seat 31. Based on Figure 2 the orientation shown, the sensing unit 60 is disposed above the second bracket 32. Alternatively, the sensing unit 60 may also be disposed at other suitable positions of the head assembly 100. In one or more embodiments, the sensing unit 60 includes a camera 61 and a backing plate 62. The backing plate 62 is disposed between the camera 61 and the second bracket 32 to prevent the image captured by the camera 61 from being blurred when the first steering device 20 and the second steering device 30 are operating, so that it is difficult for the robot to make a correct response. In an alternative embodiment, the camera 61 may also be replaced with other suitable sensing elements, such as an infrared imaging device, a lidar, etc.

[0030] The present utility model also provides a robot. The robot includes the above-mentioned head assembly 100, thereby having higher flexibility to better complete the operation task.

[0031] So far, the technical solutions of the present utility model have been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present utility model.
