Description

Technical Field

[0003] Currently, research on bionic robots mainly focuses on behaviors such as robot perception, human-like hand movements, and human-like gait. There is relatively little research on the face and expressions of bionic robots. Many researchers use human-like blinking to achieve expressions, such as simply realizing the movement of the eyelids. However, the expressions achieved are often relatively simple and do not achieve the expected results. Summary of the Invention

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide an eye component for a robot.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0048] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0049] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0051] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

"Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0053] In related technologies, research on bionic robots mainly focuses on behaviors such as robot perception, human-like hand movements, and human-like gait. Research on the face and expressions of bionic robots is relatively limited. Many researchers have tried to achieve the expression of blinking by moving the eyelids through the eye structure. However, the eyeballs cannot coordinate their movements, resulting in expressions that are often limited and do not achieve the desired effect.

[0054] like Figures 1 to 3 As shown, in order to solve the above-mentioned technical problems, the embodiments of this application provide an eye component 100 for a robot. The eye component 100 is used on the robot to realize bionic facial expressions and movements, thereby increasing entertainment value and bionic effect.

[0055] The eye assembly 100 includes: a support 110, an eyelid component 140, an eyeball component 150, a first linkage mechanism 160, a second linkage mechanism 161, a hinge component 170, and a drive mechanism 180.

[0056] The bracket 110 is provided with a first rod 120 and a second rod 130 spaced apart, and both the first rod 120 and the second rod 130 are rotatably connected to the bracket 110. For example, the first rod 120 and the second rod 130 are arranged parallel to each other.

[0057] The eyelid component 140 is rotatably connected to the support 110, and the eyelid component 140 defines an accommodating space 1401, with at least a portion of the eyeball component 150 located within the accommodating space 1401.

[0058] One end of the first linkage mechanism 160 is hinged to the eyeball component 150, and the other end of the first linkage mechanism 160 is hinged to the first rod component 120. One end of the second linkage mechanism 161 is hinged to the eyeball component 150, and the other end of the second linkage mechanism 161 is hinged to the second rod component 130. The hinge positions of the first linkage mechanism 160 and the second linkage mechanism 161 to the eyeball component 150 are different. For example, the hinge position of the first linkage mechanism 160 to the eyeball component 150 can be set at the upper or lower end of the eyeball component 150, and the hinge position of the second linkage mechanism 161 to the eyeball component 150 can be set at the left or right end of the eyeball component 150. This facilitates the rotation of the eyeball component 150 in the up, down, left, and right directions.

[0059] See also Figure 4 As shown, the hinge 170 is connected to the eyeball 150, and the hinge 170 is fixedly connected to the bracket 110.

[0060] The driving mechanism 180 is connected to the first rod 120 and the second rod 130 respectively, and is used to drive the first rod 120 and the second rod 130 to rotate.

[0061] The robot eye assembly 100 provided in the embodiments of this application hinges a first linkage mechanism 160 to the first link 120 and the eyeball 150, and a second linkage mechanism 161 to the second link 130 and the eyeball 150, respectively. Under the action of the drive mechanism 180, the first link 120 and the second link 130 rotate, which correspondingly drives the first linkage mechanism 160 and the second linkage mechanism 161 to transmit power. At the same time, the dynamic rotation of the eyeball 150 is achieved by the different hinge positions of the first linkage mechanism 160 and the second linkage mechanism 161 with the eyeball 150. In addition, the limiting effect of the hinge member 170 prevents the eyeball 150 from rotating too much, thereby improving the realism of the eye assembly 100 in imitating humans or other animals and increasing the facial expressions of the eye assembly 100.

[0062] like Figure 2 and Figure 5As shown, in one embodiment of this application, the drive mechanism 180 includes: a first drive member 181, a first transmission member 182, a second drive member 183, and a second transmission member 184.

[0063] Specifically, one end of the first transmission member 182 is connected to the output end of the first drive member 181, and the other end of the first transmission member 182 is connected to the first rod member 120. The first drive member 181 drives the first transmission member 182 to rotate the first rod member 120, so that the first rod member 120 drives the first linkage mechanism 160 to rotate, so that the eyeball member 150 rotates under the action of the first linkage mechanism 160 and the hinge member 170.

[0064] One end of the second transmission member 184 is connected to the output end of the second drive member 183, and the other end of the second transmission member 184 is connected to the second rod member 130. The second drive member 183 drives the second transmission member 184 to rotate the second rod member 130, so that the second rod member 130 drives the second linkage mechanism 161 to rotate, so that the eyeball member 150 rotates under the action of the second linkage mechanism 161 and the hinge member 170.

[0065] It is understandable that the first driving component 181 and the second driving component 183 can be activated independently to ultimately achieve the rotation of the eyeball component 150. Of course, the first driving component 181 and the second driving component 183 can also be activated simultaneously, correspondingly driving the first linkage 120 and the second linkage 130 to rotate. Under the action of the first linkage mechanism 160 and the second linkage mechanism 161, they jointly drive the eyeball component 150 to rotate, realizing various actions of the eyeball component 150.

[0066] It should be noted that the first driving component 181 and the second driving component 183 can be drive motors. Of course, the first driving component 181 and the second driving component 183 can also be other power sources with driving functions.

[0067] like Figure 4 As shown, in one embodiment of this application, the robot's eye assembly 100 further includes a first connector 121 and a second connector 131.

[0068] See also Figure 6As shown, the first connector 121 has a first connecting hole 1211, and the first rod 120 is fixedly inserted through the first connecting hole 1211. Exemplarily, the first rod 120 includes a first rod segment 1201 and a second rod segment 1202, which are connected by a screw. A gap 1203 is formed after the first rod segment 1201 and the second rod segment 1202 are connected. At this time, the first connecting hole 1211 is located within the gap 1203. The edge of the first connecting hole 1211 of the first connector 121 abuts against the first rod segment 1201 and the second rod segment 1202, causing it to be pressed and fixed onto the first rod 120 by the first rod segment 1201 and the second rod segment 1202. This design structure of the first rod 120 facilitates assembly with the first connector 121.

[0069] In addition, the first connecting member 121 is also provided with a first mounting position 1212 and a second mounting position 1213. The first mounting position 1212 is connected to the first transmission member 182, and the second mounting position 1213 is connected to the first linkage mechanism 160. For example, both the first mounting position 1212 and the second mounting position 1213 are pin holes. The end of the first transmission member 182 away from the first driving member 181 is connected to the first connecting member 121 through the pin hole by a pin shaft. The end of the first linkage mechanism 160 away from the eyeball member 150 is connected to the first connecting member 121 through the pin hole by a pin shaft.

[0070] It should be noted that the structure of the second connecting member 131 is the same as that of the first connecting member 121. The second connecting member 131 has a second connecting hole, through which the second rod 130 is fixedly inserted. The second connecting member 131 also has a third mounting position and a fourth mounting position. The third mounting position is connected to the second transmission member 184, and the fourth mounting position is connected to the second linkage mechanism 161. Exemplarily, the third and fourth mounting positions are also pin holes.

[0071] Specifically, the first driving member 181 drives the first transmission member 182 to rotate, which in turn drives the first rod 120 and the first linkage mechanism 160 to rotate via the first connecting member 121. Similarly, the second driving member 183 drives the second transmission member 184 to rotate, which in turn drives the second rod 130 and the second linkage mechanism 161 to rotate via the second connecting member 131, ultimately realizing the rotation of the eyeball 150.

[0072] like Figure 4As shown, in the embodiments of the first transmission member 182 and the second transmission member 184 described above, the first transmission member 182 further includes a first connecting portion 1821 and a second connecting portion 1822. The first connecting portion 1821 is connected to the output end of the first driving member 181. For example, if the first connecting portion 1821 is a wheel-shaped structure, a portion extending along the edge of the wheel-shaped structure is connected to one end of the second connecting portion 1822, and the other end of the second connecting portion 1822 is connected to the first mounting position 1212. In this embodiment, the second connecting portion 1822 can be a long, thin plate-like structure to reduce its own space occupation. Of course, in other embodiments, the first connecting portion 1821 and the second connecting portion 1822 can also be other shapes.

[0073] It should be noted that the structure of the second transmission member 184 is the same as that of the first transmission member 182. The second transmission member 184 includes a third connecting portion and a fourth connecting portion. The third connecting portion is connected to the output end of the second drive member 183, and one end of the third connecting portion is connected to the fourth connecting portion. The other end of the fourth connecting portion is connected to the third mounting position. The structure of the third connecting portion is the same as that of the first connecting portion 1821, and the structure of the fourth connecting portion is the same as that of the second connecting portion 1822. For illustrative purposes, two drive members and two transmission members are provided here; that is, one drive member is connected to a rod member via a transmission member, and the other drive member is connected to another rod member via another transmission member. This allows the two linkage mechanisms to be driven to achieve different orientations of the eyeball member 150.

[0074] like Figure 2 As shown, a universal ball joint structure 190 is further provided at the connection between the first linkage mechanism 160 and the second mounting position 1213. The universal ball joint structure 190 enables multi-angle rotational connection between the first linkage mechanism 160 and the first connecting member 121. It is understood that a universal ball joint structure 190 is also provided at the connection between the first linkage mechanism 160 and the eyeball member 150 to achieve more precise rotational movements.

[0075] It is understandable that a universal ball joint structure 190 may also be provided at the connection between the second linkage mechanism 161 and the fourth mounting position. Simultaneously, a universal ball joint structure 190 is also provided at the connection position between the second linkage mechanism 161 and the eyeball component 150.

[0076] like Figure 5 and Figure 7 As shown, in one embodiment of this application, the eyeball component 150 includes a support portion 151 and an eyeball portion 152.

[0077] Specifically, the support portion 151 has a ring-shaped structure, and a first lifting lug 1511 and a second lifting lug 1512 are provided at intervals along the circumference of the support portion 151. For example, the first lifting lug 1511 is located at the upper end of the support portion 151, and the second lifting lug 1512 is located at the left end of the support portion 151. The first lifting lug 1511 is connected to the first linkage mechanism 160. Optionally, the first lifting lug 1511 and the first linkage mechanism 160 are connected by a pin, and the second lifting lug 1512 and the second linkage mechanism 161 are also connected by a pin. Exemplarily, the support portion 151 has a circular ring-shaped structure.

[0078] See also Figure 8 As shown, the eyeball portion 152 is fixed to the support portion 151 on the side away from the first lug 1511, and the eyeball portion 152 is located on one side of the first linkage mechanism 160 and connected to the hinge member 170. Specifically, the middle position of the eyeball portion 152 is connected to the hinge member 170 to prevent the eyeball portion 152 from rotating only in the vertical plane when the first linkage structure and the second linkage mechanism 161 drive it to rotate. Through the hinge restriction effect of the hinge member 170, the eyeball portion 152 can rotate simultaneously in the horizontal and vertical planes, improving the realistic effect of the eyeball portion 152 imitating the rotation of humans or other animals.

[0079] like Figure 8 and Figure 9 As shown, in one embodiment of this application, the hinge 170 includes a first bearing 171, a cross shaft 172, and a second bearing 173; the cross shaft 172 includes a first shaft body 1721 and a second shaft body 1722 arranged orthogonally, the first shaft body 1721 and the second shaft body 1722 are perpendicularly connected, the first shaft body 1721 and the second shaft body 1722 can be integrally formed, or they can be detachably connected and fixed.

[0080] The first bearing seat 171 is fixed to the bracket 110. The end of the first bearing seat 171 away from the eyeball 152 can be connected to the bracket 110 by bolts or welding. The end of the first bearing seat 171 away from the bracket 110 has a first U-shaped opening 1711. The two opposite sidewalls of the first U-shaped opening 1711 are provided with first shaft holes 1712. The first shaft body 1721 passes through the two first shaft holes 1712.

[0081] The second bearing 173 is connected to the eyeball portion 152. The second bearing 173 can be integrally formed with the eyeball portion 152, or it can be fixed by welding or screwing. The second bearing 173 has a second U-shaped opening 1731, which is opposite to the first U-shaped opening 1711. The two opposite sidewalls of the second U-shaped opening 1731 are provided with second shaft holes 1732, and the second shaft body 1722 passes through the two second shaft holes 1732.

[0082] In this embodiment, the hinge 170 is configured to rotate up, down, left, and right.

[0083] It should be noted that the eyeball portion 152 is hemispherical, and the direction of the eyeball portion 152 toward the first bearing 171 is a hollow structure.

[0084] like Figure 9 As shown, in the embodiment of the cross shaft 172 described above in this application, the cross shaft 172 has a through hole 1723 along a preset direction, which is perpendicular to the axial direction of the first rod 120. The through hole 1723 facilitates the assembly of the camera when it is installed in the eyeball part 152, thus making the structure of the eyeball part 150 more compact and reducing the space occupied.
