Description

Technical Field

[0001] The invention belongs to the technical field of robots, and in particular relates to a multi-freedom head and neck of a novel intelligent robot. Background Art

[0002] Automatic control machines include all machines that simulate human behavior or thoughts and simulate other organisms, such as robot dogs and robot cats. In a narrow sense, there are many classifications and controversies about the definition of robots. Some computer programs are even called robots. In contemporary industry, robots refer to man-made machine devices that can automatically perform tasks to replace or assist human work. The ideal high-simulation robot is the product of advanced integrated cybernetics, mechatronics, computers and artificial intelligence, materials science and bionics. The scientific community is currently conducting research and development in this direction. Nowadays, welcoming service robots are used in some welcoming services, but the existing welcoming service robots have only two degrees of freedom in their heads, namely rotation and pitch. The degrees of freedom are relatively low, which affects the simulation effect of the welcoming robot. For example, a new type of intelligent robot with multiple degrees of freedom head and neck is proposed in patent announcement number CN111531525B.

[0003] In actual use environments, the existing multi-degree-of-freedom head and neck robot may be subjected to unexpected collisions or impacts, and its structural impact resistance is relatively weak, which can easily lead to damage to internal mechanical components or sensor failure. Compared with the human head and neck, the human body's bones, muscles and soft tissues can buffer external impacts to a certain extent, while the mechanical structure of the robot's head and neck is often designed with more emphasis on precision and flexibility, and relatively less consideration is given to impact resistance. The setting of rigid protective devices will affect the flexibility of the robot's head and neck.

[0004] Therefore, a new type of intelligent robot with multi-degree-of-freedom head and neck is proposed to solve the above problems. Summary of the invention

[0028] The operating principle of the present invention is now explained as follows: the upper fixing ring 23 and the neck mounting frame 15 are fixed by bolts, and then the air outlet pipe 19 and the annular tube 17 are connected. Since the protective cover 161 and the buffer air bag 162 are made of rubber, the protective cover 161 and the buffer air bag 162 can be compressed to facilitate the connection between the air outlet pipe 19 and the annular tube 17. Then, the lower connecting tube 7 is installed on the upper side of the rotating plate 3 by bolts, and then the lower fixing ring 23 and the rotating plate 3 are connected together by bolts, and the inflatable protective assembly 16 can be installed. After the inflatable protective assembly 16 is installed, the operator transmits an electrical signal to the PLC controller 4 through an external remote control device. After receiving the electrical signal, the PLC controller 4 will drive the air pump 18 to work and control the first control valve 21 to open. The air pump 18 will transmit the external gas filtered by the activated carbon filter plate 31 to the inside of the protective cover 161 through the air outlet pipe 19 and the short pipe 20, and then use The protective cover 161 is inflated with gas. When the air pressure inside the protective cover 161 continues to increase, the air pressure inside the air outlet pipe 19 will also increase. The air outlet pipe 19 is connected to the air pressure cylinder 241. When the air pressure inside the air outlet pipe 19 increases, a part of the gas will enter the air pressure cylinder 241, so that the air pressure in the space on the left side of the piston plate 25 increases, and the piston plate 25 will continue to move to the right. In the process of moving to the right, the piston plate 25 will squeeze the trigger switch 26. The trigger switch 26 will control the first control valve 21 to close and the second control valve 22 to open through the PLC controller 4, so that the gas is transported to the multiple buffer airbags 162 through the annular tube 17. When the air pressure inside the multiple buffer airbags 162 reaches the set air pressure, referring to the above principle, the piston plate 25 will squeeze the trigger switch 26 again, and the trigger switch 26 will control the air pump 18 to stop working immediately, so that the protective cover 161 and the buffer airbag 162 protect the head and neck; When the robot's head needs to be rotated, the PLC controller 4 will control the first motor 6 to work, and the first motor 6 controls the rotating column 5 and the rotating plate 3 to rotate together through the bevel gear transmission assembly, and the rotating plate 3 can drive the robot head above the neck mounting frame 15 to rotate. When the robot's head needs to be controlled to twist left and right, the PLC controller 4 will control the second motor 9 to work, and the second motor 9 controls the longitudinal rod 8 to rotate through the pulley transmission assembly, and the longitudinal rod 8 will drive the neck mounting frame 15 to twist left and right. Similarly, when the robot's head is controlled to pitch forward and backward, it is only necessary to control the third motor 13 to work; When the cushioning airbag 162 is subjected to a severe external impact, the pressure on the gas inside the cushioning airbag 162 will increase rapidly and exceed the bearing range of the pressure valve 45. After being subjected to a greater impact, part of the gas inside the cushioning airbag 162 will enter the trigger box 46 through the pressure valve 45 and the vertical pipe 44, increasing the air pressure in the space below the piston seat 47. The piston seat 47 will drive the conductive block 48 to move upward and contact the conductive plate 49. The conductive block 48 is electrically connected to the external power supply, and the conductive plate 49 is electrically connected to the warning light 50. When the two are in contact, the warning light 50 will light up, making it convenient for the operator to find the exact location where the head and neck are hit and to inspect the location.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
