Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to a facial structure for a robot and the robot itself. Background Technology

[0002] In recent years, with the rapid development of technology, the humanoid robot industry has developed particularly rapidly. As human-computer interaction scenarios expand, robot heads need to have facial features and expressive abilities that are closer to those of humans. Traditional silicone or plastic materials cannot simulate the touch and dynamic micro-expressions of real skin, leading to the "uncanny valley effect" for users. Early robot faces were mainly rigid mechanical structures, which could achieve limited facial expressions.

[0003] Therefore, there is an urgent need for a robot facial structure that can achieve a stereoscopic eye display effect and mimic human facial expressions. Utility Model Content

[0009] As a further improvement of this utility model, a light strip is provided circumferentially on the upper part of the cover plate mounting hole, and a light strip uniform light bar is provided on the light strip. The MIC board of the cover plate assembly is embedded and fixed to the upper part of the front frame with screws so as to realize the sound receiving function through the MIC board.

[0010] As a further improvement of this utility model, the MIC plate is installed inside the mounting hole of the cover plate, and the depth ratio of the mounting hole between the MIC plate and the top cover is greater than 0.5.

[0011] As a further improvement of this utility model, the top cover has an arc-shaped structure, and the decorative mesh is a mesh structure embedded and pasted on the outside of the top cover.

[0012] As a further improvement of this utility model, the decorative mesh has an opening ratio of more than 50% and an aperture of more than 0.8 mm.

[0013] As a further improvement of this utility model, the screen mounting bracket is provided with two circular through holes in the middle, and the spherical glass lens is embedded in the circular through holes on the front of the screen mounting bracket and bonded together with double-sided adhesive.

[0014] The display screen is embedded on the back of the screen mounting bracket and is pressed together with the screen mounting bracket by the PCBA mounting bracket.

[0015] As a further improvement of this utility model, the PCBA mounting bracket is fixed to the screen mounting bracket with screws, and the PCBA mounting bracket has a number of support points spaced apart on the side facing the display screen to ensure the stability of the display screen installation.

[0016] As a further improvement of this utility model, the PCBA board is fixed on the PCBA mounting bracket and connected to the FPC board connected to the lower part of the display screen, so as to supply power to the display screen through the PCBA board.
