Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of robot, and relates to a lifelike device, in particular to an ear structure of an AI child companion robot. BACKGROUND

[0002] The AI child companion robot is an interactive doll, which can react to sound input, thereby realizing a question and answer conversation function. In the prior art, a single question and answer function cannot meet the needs of users for product appearance and interactive experience. Therefore, people have made long-term exploration and proposed various solutions.

[0003] For example, the Chinese patent document discloses a voice recognition interactive doll [application number: 200310101622.5], which mainly comprises a microphone, a voice control device, a player and a peripheral device fixed in a doll body with a human appearance.

[0004] The above-mentioned scheme designs a doll body with a human appearance, but only has a simple external shape. The interactive experience is general, and therefore the needs of users cannot be met. SUMMARY

[0005] The utility model aims at the above-mentioned problem, and provides an ear structure of an AI child companion robot which is flexible and movable.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: the ear structure of the AI child companion robot comprises an ear body, a hinge structure capable of being connected with a shell is arranged on the ear body, the ear body is connected with a driving mechanism through an elastic component, and the driving mechanism drives the ear body to rotate around the hinge point through the elastic component.

[0007] The ear body is driven to rotate around the hinge point through the driving component, has the effect of simulating ear movement, and is connected with the driving mechanism through the elastic component, can play a buffering role when motion is conducted, prevents unnatural shaking, and has the effect of improving the degree of realism.

[0008] In addition, the elastic component 2 is arranged, so that in the case that the ear body is touched by external force, the remaining part of the mechanism is not damaged due to the external force, the product durability is increased, and the interactivity of the product is also increased.

[0009] In the above-mentioned ear structure of the AI child companion robot, the hinge structure comprises a hinge hole or a hinge shaft arranged on the ear body, and the shell is provided with a hinge pin or a butt joint hole corresponding to the hinge hole or the hinge shaft. The hinge structure is matched with the hinge pin or the butt joint hole on the shell through the hinge hole or the hinge shaft, and the design can ensure the stable connection between the ear body and the shell and prevent loosening or falling off.

[0010] In the ear structure of the AI companion robot, the driving mechanism includes a lifting support and a lifting driving assembly, and the lifting support is connected with the ear body through the elastic assembly. The lifting support is connected with the ear body through the elastic assembly, which not only ensures the stability of the ear body during movement, but also can alleviate the influence of external impact on the ear body to a certain extent.

[0011] In the ear structure of the AI companion robot, the lifting driving assembly includes a rack connected with the lifting support, the rack is driven by a gear, the gear is connected with a rotary driver, and the rack is connected with a housing radially limited axial sliding. The meshing transmission of the rack and the gear has high stability and reliability, which can ensure the smooth transmission of the action and reduce the shaking or error caused by unstable transmission.

[0012] In the ear structure of the AI companion robot, the housing is provided with a rack sliding rail, and the rack is connected with the rack sliding rail through a rack sliding block;

[0013] And / or, the housing is provided with a guide groove, and the lifting support is provided with a guide sliding block capable of sliding in the guide groove;

[0014] And / or, the housing is provided with a guide column, and the lifting support is sleeved on the guide column through a strip-shaped hole.

[0015] The rack is connected with the rack sliding rail and the sliding block through the pressing of the gear, which can avoid the shaking or tilting of the rack during sliding and achieve the effect of avoiding failure.

[0016] In the ear structure of the AI companion robot, one end of the gear is provided with the rotary driver, and the other end is connected with an angle position sensor. The setting of the angle sensor can introduce angle signal feedback, and more accurate adjustment control can be realized.

[0017] In the ear structure of the AI companion robot, a rotary limiting structure capable of limiting the rotation angle when the ear body rotates around the hinge point is arranged between the ear body and the housing. The setting of the rotary limiting structure can avoid damage to the associated mechanical structure when excessive rotation occurs due to accident.

[0018] In the ear structure of the AI companion robot, the rotation limiting structure includes a rotating sleeve arranged at one end of the hinge hole, a stroke limiting hole is formed in the rotating sleeve, a limiting block connected with the shell is arranged in the stroke limiting hole, and an oscillation gap is arranged around the hinge hole in the circumferential direction between the stroke limiting hole and the limiting block. The cooperation of the stroke limiting hole and the limiting block can accurately control the rotation angle and position of the rotating part. When the rotating part rotates to the predetermined position, the limiting block is accurately embedded in the stroke limiting hole, thereby limiting the further rotation of the rotating part. By arranging the oscillation gap, the friction and collision between the rotating part and the limiting block can be reduced, thereby prolonging the service life of the equipment.

[0019] In the ear structure of the AI companion robot, the elastic assembly includes a double torsion spring arranged on the lifting support, and two spring legs of the double torsion spring are arranged on the linkage column deviated from the rotation center of the ear body. The design of the double torsion spring enables the spring legs to be stably arranged on the linkage column, and such a structure can provide stable elasticity and support force for the whole system, and can effectively reduce vibration and shaking caused by movement.

[0020] In the ear structure of the AI companion robot, the ear body has two ears arranged on the two sides of the lifting support, and the two ears are connected with the lifting support through respective elastic assemblies. The two ears and the corresponding elastic assemblies share the overall load. Such a load dispersion mode helps to reduce the stress intensity of a single component, thereby prolonging the service life of the whole structure.

[0021] Compared with the prior art, the ear structure of the AI companion robot has the advantages that: 1. The movable design of the ear part can improve the interactive experience of the user. 2. The introduction of the elastic assembly improves the durability and the higher degree of simulation. 3. The structure is simple and compact, the required installation space is small, and the service life is long. BRIEF DESCRIPTION OF DRAWINGS
