[0023] like Figures 1-2 As shown, a humanoid robot head display device includes a front shell 2 and a rear shell 3. A display screen 1 is fixedly installed in the middle of the front shell 2. The front shell 2 and the rear shell 3 are fixedly connected by screws to form a receiving cavity 4. A support plate 9 is fixedly installed in the receiving cavity 4 near the bottom. A lower bracket 8 is fixedly installed on the support plate 9. A hinge hole is opened above the lower bracket 8. A servo hinge mechanism 6 is fixedly installed in the hinge hole. An upper bracket 7 is hinged to the lower bracket 8 through the servo hinge mechanism 6. A projection device 5 is fixedly installed on the upper bracket 7.
[0024] like Figure 3 As shown, the projection device 5 includes a miniature laser projector 501, which is fixedly connected to the upper bracket 7. The miniature laser projector 501 can project text, images, and other content onto the display screen 1 and has an automatic focus function. A camera device 502 is fixedly installed on the front housing of the miniature laser projector 501. The camera device 502 includes a set of depth cameras 5021 and a color camera 5022. The depth camera 5021 is used to obtain the distance information of the object from the camera, and the color camera 5022 is used to capture the color, texture, and other information of the object.
[0025] like Figure 4 As shown, the servo hinge mechanism 6 includes a servo motor 601. The power output end of the servo motor 601 is connected to a reduction gear 602. The servo motor 601 outputs rotational power to drive the reduction gear 602 to work, further driving the upper bracket 7 to rotate around the hinge hole, thereby realizing the adjustment of the projection angle of the micro laser projector 501. After the adjustment is completed, the self-locking function of the servo motor 601 ensures that the micro laser projector 501 is locked in the corresponding position.
[0026] In this embodiment, the speed reduction device 602 is a prior art technology used to reduce the rotational speed and increase the torque.
[0027] In operation, the camera 502 captures images projected by the micro laser projector 501 onto the surface of the display screen 1 or outside in real time, collects data information such as distance, size, color, light intensity of the images and feeds back to the control system, the control system compares the data information fed back by the camera 502 with standard data information in the database, issues a control signal, controls the micro laser projector 501 to automatically adjust the focal length, and controls the servo motor 601 to work at the same time, outputs rotary power to drive the reduction device 602 to work, realizes adjustment of the projection angle of the micro laser projector 501, and achieves the best projection effect.
[0028] In the embodiment, the display screen 1 is an electrically controlled liquid crystal glass, and the transparency thereof is controlled by controlling the voltage inside the display screen 1 after being electrified, in a certain range, the higher the voltage, the higher the transparency, and finally the display screen 1 is completely transparent; when the voltage is 0, the display screen 1 is opaque.
[0029] When the display screen 1 is in a semi-transparent state, the light of the micro laser projector 501 can pass through the surface of the display screen 1 without penetrating the display screen 1, so as to form an image outside the display screen 1, so that a person can see the image of the face of the humanoid robot outside the shell.
[0030] When the display screen 1 is in a fully transparent state, the light of the micro laser projector 501 can completely penetrate the display screen 1, so as to form a projection image on an object outside the humanoid robot, the control system controls the micro laser projector 501 to adjust to the best projection state, at this time, the humanoid robot can be used as a mobile projector in industrial, commercial or life scenes, compared with products with unadjustable transparency of the display screen 1, the application range is wider, for example, when a large equipment needs to be repaired, the display screen 1 is adjusted to a fully transparent state, and the part to be repaired is marked by the projector, which is more intuitive and accurate.
[0031] For those skilled in the art, according to the teaching of the present application, the changes, modifications, replacements and variations of the embodiments without departing from the principles and spirits of the present application still fall within the protection scope of the present application.
