Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of robots, and particularly to a robot neck structure and a robot. Background Art
[0002] With the development of humanoid robots and AI, robots with flexible necks can obtain more information about the surrounding environment and maintain the stability of the head during movement. Therefore, the neck mechanisms of robots with bionic appearance and flexible movements have become a research and development hotspot. However, traditional three-degree-of-freedom (Yaw, Pitch, Roll) neck structures often have the following problems in terms of spatial layout and load distribution:
[0003] Large space occupation: Yaw, Pitch, and Roll often use independent drive units, and the motors of each axis are separately installed, resulting in a relatively large overall height or width of the neck, making it difficult to meet the requirements of miniaturization and aesthetics.

[0037] Embodiment 1
[0038] An embodiment of the present application discloses a robot neck structure, including a torso connection platform 100, on which a turntable 110 is rotatably arranged; a first rotation drive assembly 200 is arranged at the bottom of the torso connection platform 100, and the first rotation drive assembly 200 drives and connects the turntable 110; the first end of a universal coupling assembly 300 is connected to the turntable 110, and the second end of the universal coupling assembly 300 is connected to a head connection platform 400; the universal coupling assembly 300 includes a first rotating shaft portion 310 extending along a first direction X and a second rotating shaft portion 320 extending along a second direction Y; a second rotation drive assembly 500 and a third rotation drive assembly 600 are connected to the head connection platform 400. The output shaft of the second rotation drive assembly 500 is ball-jointed to the turntable 110 through a first link assembly 700, and the third rotation drive assembly 600 is ball-jointed to the turntable 110 through a second link assembly 800. The second rotation drive assembly 500 and the third rotation drive assembly 600 drive and cooperate to enable the head connection platform 400 to have a tendency of swinging the head and a tendency of nodding the head, and jointly share the inertia of the head connection platform 400 through the second rotation drive assembly 500 and the third rotation drive assembly 600.
[0039] In this embodiment, the torso connection platform 100 is provided to connect the torso part of the robot. A turntable 110 is rotatably arranged on the torso connection platform 100. A first rotation driving component 200 is arranged at the bottom of the torso connection platform 100 to drive and connect the turntable 110 to drive it to rotate. It can be understood as driving the neck structure of the robot to perform a rotational motion. And the first rotation driving component 200 is arranged at the bottom of the torso connection platform 100. Since the torso part itself has a relatively large space, there is enough space for convenient installation of the first rotation driving component 200. At the same time, it can reduce the occupation of the robot's neck space, which is beneficial to the miniaturization of the structure. A head connection platform 400 is connected to the turntable 110 through a universal coupling component 300, so that the head connection platform 400 also has degrees of freedom in multiple directions, such as swinging the head left and right (which can be understood as the rotational degree of freedom of the first rotating shaft part 310) and nodding up and down (which can be understood as the rotational degree of freedom of the second rotating shaft part 320). A second rotation driving component 500 and a third rotation driving component 600 are connected to the head connection platform 400. The output shaft of the second rotation driving component 500 is ball-jointed to the turntable 110 through a first link component 700. The third rotation driving component 600 is ball-jointed to the turntable 110 through a second link component 800. So that by controlling the driving modes of the second rotation driving component 500 and the third rotation driving component 600 and cooperating with the universal coupling component 300 to control whether the head connection platform 400 performs a head-swinging motion or a nodding motion. In this way, whether it is a head-swinging motion or a nodding motion, the head inertia can be dispersed to two motors to bear, reducing the single-axis load. It can also be understood that the head-swinging motion and the nodding motion are "paralleled". The two driving components are ball-jointed to the turntable 110 and cooperate with the universal coupling component 300 to complete the head-swinging motion and the nodding motion. In summary, in this application, the nodding action can be completed through the first rotation driving component 200. The left and right head-swinging and up and down nodding actions can be completed through the second rotation driving component 500 and the third rotation driving component 600 and ensure their stable progress, so as to realize the highly anthropomorphic motion of the robot's neck structure. At the same time, through the universal coupling component 300 and the ball joint, the load and inertia are shared, so that smaller torque and lighter motors can be selected, and this structure can effectively utilize space, making the neck mechanical mechanism more suitable for bionic requirements in terms of external dimensions and functions.
[0040] In an optional or preferred embodiment, a receiving space 120 is arranged at the bottom of the torso connection platform 100, and the first driving member 210 is installed in the receiving space 120. Through the arrangement of the receiving space 120, the installation of the first driving member 210 can be facilitated, and at the same time, the occupation of the neck area space can be reduced.
[0041] In an alternative or preferred embodiment, the first rotation drive assembly 200, the second rotation drive assembly 500, and the third rotation drive assembly 600 can all be configured to include, but are not limited to, motors, servos, motors, and the like.
[0042] In an alternative or preferred embodiment, the output shafts of the second rotation drive assembly 500 and the third rotation drive assembly 600 are arranged to face away from each other in the first direction X and are spaced apart in the second direction Y; the first link assembly 700 includes a first rotating arm 710; the second link assembly 800 includes a second rotating arm 810; the output shaft of the second rotation drive assembly 500 is connected to the first rotating arm 710; the output shaft of the third rotation drive assembly 600 is connected to the second rotating arm 810; the first rotating arm 710 and the second rotating arm 810 are arranged to face each other in the second direction Y; wherein, the first direction X and the second direction Y are perpendicular to each other on a horizontal plane.
[0043] In this embodiment, for the convenience of understanding the technical solution, the first direction X and the second direction Y are marked in the attached Figure 1 as a reference; in the prior art, most of the robot neck structures have the situation that the overall height, width or depth of the neck is relatively large, which affects the aesthetics and compactness of the robot neck appearance. To solve this problem, the present application specifically designs the following solution. Please refer to the attached Figures 1-4 , the first link assembly 700 includes a first rotating arm 710; the second link assembly 800 includes a second rotating arm 810; the output shaft of the second rotation drive assembly 500 is connected to the first rotating arm 710; the output shaft of the third rotation drive assembly 600 is connected to the second rotating arm 810; on this basis, the output shafts of the second rotation drive assembly 500 and the third rotation drive assembly 600 are arranged to face away from each other in the first direction X and are spaced apart in the second direction Y, and the first rotating arm 710 and the second rotating arm 810 are arranged to face each other in the second direction Y. Referring to the attached Figure 4 , the first rotating arm 710 on the right side is arranged from back to front, and the second rotating arm 810 on the left side is arranged from front to back, that is, the output shaft connected to the first rotating arm 710 is arranged behind the output shaft connected to the second rotating arm 810 (the front and back directions here can be understood as the second direction Y); thereby achieving the purpose of compact structure and miniaturization of volume.
[0044] Preferably, please refer to Figure 2 、 Figure 3, the first rotating arm 710 is close to the driving part body of the second rotating drive assembly 500 in the first direction X and does not extend beyond the driving part body of the second rotating drive assembly 500 in the second direction Y; the second rotating arm 810 is close to the third rotating drive assembly 600 in the first direction X and does not extend beyond the driving part body of the third rotating drive assembly 600 in the second direction Y; for ease of understanding, specific orientations will be introduced later, which should not be regarded as a limitation thereto, and the examples are as follows: such as Figure 3 , bringing the first rotating arm 710 and the second rotating arm 810 close to the motor body can reduce the space occupied in the left - right direction of the neck area; such as Figure 2 , the first rotating arm 710 and the second rotating arm 810 will not extend beyond the driving bodies of the second rotating drive assembly 500 and the third rotating drive assembly 600 in the second direction Y, which can effectively reduce the space occupied in the front - back direction of the neck area, and through the structural design of the present application, when the robot nods or shakes its head, the rotation angles of the first rotating arm 710 and the second rotating arm 810 do not need to be very large. Therefore, even during the movement process, the first rotating arm 710 and the second rotating arm 810 will never extend beyond the motor bodies of the second rotating drive assembly 500 and the third rotating drive assembly 600. Further, arranging the second rotating drive assembly 500 and the third rotating drive assembly 600 closely along the first direction X or along the second direction Y can also reduce the space occupied in the height direction of the neck area. With such a design, it can be made that the present application can greatly reduce the space occupied in the neck area in all directions, which is beneficial to the miniaturization design of the robot neck.
[0045] In an alternative or preferred embodiment, the first link assembly 700 further includes a first ball - head link 720.
