Description

Technical Field

[0001] The utility model relates to the technical field of humanoid robots, in particular to a head structure of a humanoid robot for exhibition halls. Background Technique

[0002] A robot designed and manufactured by imitating the form and behavior of a human is a humanoid robot, which generally has human-like limbs and a head separately or simultaneously. With the rapid development of artificial intelligence and robot technology, humanoid robots have broad application prospects in the fields of education, entertainment, medical treatment, and service.

[0003] The existing humanoid robots have the following drawbacks in the use process: the mouth of the existing humanoid robot is generally a fixed structure and can only perform simple opening and closing actions under the action of an external power component. During use, it is impossible to simulate the corresponding mouth shapes according to the pronunciation of the robot, which affects the detailed experience of using the humanoid robot. For this reason, we propose a head structure of a humanoid robot for exhibition halls. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a head structure of a humanoid robot for exhibition halls. By arranging a mouth shape adjustment mechanism on the surface of the robot head body, the mouth shape can be adjusted through a control component, and partial pronunciation mouth shapes can be simulated, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A head structure of a humanoid robot for exhibition halls includes a robot head body and also includes a mouth shape adjustment mechanism. The mouth shape adjustment mechanism is arranged on the surface of the robot head body. The mouth shape adjustment mechanism includes a mouth cover, rubber strips, long rubber blocks, short rubber blocks, a micro telescopic motor A, and a micro telescopic motor B. The surface of the robot head body is provided with a mouth cover, and the mouth cover is composed of an upper lip cover and a lower lip cover. The upper lip cover and the lower lip cover are both filled with rubber strips. Long rubber blocks are arranged at the center positions on one side of the surfaces of the rubber strips, and short rubber blocks are arranged at both ends of the long rubber blocks. A micro telescopic motor A and a micro telescopic motor B are installed inside the robot head body near the mouth cover.

[0007] Furthermore, connecting rubber blocks are integrally formed at the joints between the long rubber blocks and the short rubber blocks and at the joints between the short rubber blocks. The specification of the connecting rubber blocks is smaller than that of the short rubber blocks; the short rubber blocks are connected by the connecting rubber blocks, and the specification of the connecting rubber blocks is small, so that the angle between the short rubber blocks can be flexibly adjusted when the micro telescopic motor B operates.

[0008] Furthermore, through grooves are formed at the positions corresponding to the short rubber blocks on the surface of the rubber strips; the through groove structure enables the angle of the rubber strips to be smoothly adjusted.

[0009] Furthermore, pull rods are installed at the power ends of the micro telescopic motor A and the micro telescopic motor B. The micro telescopic motor A is connected to the surface of the rubber strip through the pull rod, and the micro telescopic motor B is connected to the end of the short rubber block through the pull rod. The micro telescopic motor A and the micro telescopic motor B cooperate to adjust the mouth shape through the pull rod.

[0010] Compared with the prior art, the utility model has the following beneficial effects: A mouth cover is provided on the surface of the robot head body. The mouth cover is composed of an upper lip cover and a lower lip cover corresponding in position. Rubber strips, long rubber blocks and short rubber blocks are respectively arranged inside the upper lip cover and the lower lip cover. The micro telescopic motor A and the micro telescopic motor B installed inside the robot head body are used for regulation and control. The motor control end is connected to the robot control module. During use, the motors are adjusted in real time according to the pronunciation of the robot. When the micro telescopic motor A operates, it pushes and pulls the rubber strip through the pull rod to control the forward and backward movement of the upper lip cover and the lower lip cover. When the micro telescopic motor B operates, it squeezes or stretches the short rubber block from both sides, causing the short rubber block to change the angle around the long rubber block, thereby driving the change of the upper lip cover and the lower lip cover, simulating the approach and stretching of the lip position. By controlling the upper lip cover and the lower lip cover, and cooperating with the lower jaw control component inside the robot head body, the mouth shape is simulated for some pronunciations during pronunciation, improving the simulation of the humanoid robot.

A micro telescopic motor A 209 and a micro telescopic motor B 210 are installed inside the robot head body 1 near the mouth cover 201.

[0018] Wherein, connection rubber blocks 207 are integrally formed at the joints between the long rubber block 205 and the short rubber blocks 206 and at the joints between the short rubber blocks 206. The specification of the connection rubber block 207 is smaller than that of the short rubber block 206. Through grooves 208 are formed at the positions corresponding to the short rubber blocks 206 on the surface of the rubber strip 204. The short rubber blocks 206 are connected by the connection rubber blocks 207. The specification of the connection rubber block 207 is small, so that the angle between the short rubber blocks 206 can be flexibly adjusted when the micro telescopic motor B 210 operates. The through groove 208 structure enables the angle of the rubber strip 204 to be smoothly adjusted.

[0019] Wherein, pull rods 211 are installed at the power ends of the micro telescopic motor A 209 and the micro telescopic motor B 210. The micro telescopic motor A 209 is connected to the surface of the rubber strip 204 through the pull rod 211.
