Description
Technical Field
[0001] This utility model relates to the field of robotics technology, and in particular to a head assembly for a robot and the robot itself. Background Technology
[0002] With the development of technology, robots have been widely used in industries such as homes, healthcare, catering, and construction, bringing numerous conveniences to people's lives and production. The robot head assembly is the top structural component of the robot and is an important part for human-computer interaction.
[0003] To facilitate human-computer interaction, the robot's head typically integrates a camera module and a voice interaction module. When the angle needs to be adjusted according to the subject being photographed, the robot's head needs to perform pitching or rotating movements to adjust the recognition area of the camera module.
[0004] Currently, robots typically use geared motors to directly drive the robot head for pitching motion. This requires a relatively large space in the axial direction of the rotation axis, resulting in a less tight connection between the robot's head and body. It also limits the pitch angle of the robot's head, making it impossible to ensure that the camera module has a sufficiently wide field of view during human-computer interaction to quickly capture the interactive object.
[0005] In view of the above reasons, this utility model proposes a head assembly for a robot and a robot in order to solve the above-mentioned technical problems. Utility Model Content
[0006] The purpose of this invention is to provide a head assembly for a robot and a robot in general. The head assembly can be easily connected to the robot's torso, enabling the head to pitch and rotate widely, quickly capture interactive objects, and ensure a good interactive experience.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Example 1 like Figure 1-3 As shown, this utility model provides a robot head assembly, including: a rear shell 101, a front face shell 102, and a flexible neck collar 103. The front opening of the rear shell 101 is adapted to the edge contour of the front face shell 102, so that the front face shell 102 and the front of the rear shell 101 can be detachably connected by a snap fastener. The bottom opening of the rear shell 101 is connected to the flexible neck collar 103, and the bottom end of the flexible neck collar 103 can be connected to the robot torso.
[0024] The rear shell 101 houses a head-fixing bracket 2 detachably connected to both sides. A pitch motor bracket 3 is located inside the head-fixing bracket 2, and a pitch motor 4 is mounted inside the pitch motor bracket 3. The output shaft of the pitch motor 4 is connected to one side of the head-fixing bracket 2, and the other side of the head-fixing bracket 2 is rotatably connected to the pitch motor bracket 3. Rotation of the pitch motor 4 drives the head-fixing bracket 2, the rear shell 101, and the front shell 102 to rotate as a whole, achieving the robot's head pitching motion. The bottom of the pitch motor bracket 3 is fixedly connected to the output end of a rotary motor 5. The rotary motor 5 is fixed to a rotary motor bracket 6, which is located inside a flexible neck collar 103, and its bottom end is fixedly connected to the top of the robot's torso. The upper part of the flexible neck collar 103 is made of a plastic or resin material with a certain degree of flexibility, allowing it to deform during robot head pitching. Its bottom end is made of a rigid material and is detachably connected to the robot's torso.
[0025] like Figure 3As shown, the head fixing bracket 2 is inverted U-shaped and is made of aluminum alloy. It has multiple fixing holes 201 on both sides, which can be adapted to the fixing screw holes on both sides of the rear shell 101 and can be detachably connected by screws, so that the rear shell 101 and the front shell 102 can move together. There are also multiple sets of parallel weight reduction holes 202 on the upper side of the fixing holes 201. The weight reduction holes 202 are elongated holes, which can reduce the weight of the head fixing bracket 2.
[0026] In this embodiment, a pitch limiting bracket 7 is provided on one side bottom of the pitch motor bracket 3. The front and rear ends of the pitch limiting bracket 7 extend upward to mechanically limit the pitch angle of the head fixing bracket 2, so as to prevent it from rotating beyond the limit position and thus failing to reset.
[0027] In this embodiment, rotation limit brackets 8 are provided on both sides of the top of the rotary motor bracket 6, and a stop bar perpendicular to it is connected to the output shaft of the rotary motor 5. The rotation limit brackets 8 on both sides can mechanically limit the rotation angle of the rotary motor, and at the same time provide the function of zeroing the initial position of the zero point.
[0028] A camera mounting bracket 9 is provided on the top of the head fixing bracket 2, and an RGBD camera 10 is mounted on the camera mounting bracket 9. A camera mounting hole 11 corresponding to the position of the RGBD camera 10 is provided on the upper side of the front shell 102. The RGBD camera can simultaneously acquire color images (RGB) and depth information (D) of the scene. By combining a traditional color camera and a depth sensor, it can provide richer three-dimensional scene information than a single RGB camera.
[0029] In this embodiment, a voice interaction device 12 is provided inside the rear shell 101. The voice interaction device 12 is detachably installed inside the top of the rear shell 101 by means of a snap-fit. The voice interaction device 12 is used for voice interaction with the user and for voice wake-up and voice remote control of the robot.
[0030] In this embodiment, an eye frame 13 is provided on the lower surface of the front shell 102, and two lenses 14 are installed inside the eye frame 13, which can serve as the robot's left and right eyes respectively. A left camera 15 and a right camera 16 are provided inside the rear shell 101. The lens positions of the left camera 15 and the right camera 16 correspond to the positions of the two lenses 14 respectively, and the left camera 15 and the right camera 16 are fixed on the same binocular camera mounting bracket 19. The left camera 15 and the right camera 16 can serve as the robot's left and right eyes respectively, and can collect surrounding three-dimensional scene information when the robot's head rotates.
[0031] In this embodiment, symmetrically arranged color-changing light strips 17 are provided on both sides of the rear shell 101, and lamp covers 18 are fitted over the light strips 17. The color of the light strips 17 is variable, and in addition to its decorative function, it can also display different light colors according to the robot's normal, alarm, or fault status.
[0032] The rotary motor bracket 6 has a through-hole 20, which allows for easy electrical connection of the various components inside the head assembly to the power module and control module located inside the robot's torso.
[0033] Example 2 This utility model also provides a robot whose head adopts the robot head component disclosed in Embodiment 1.
