[0033] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.
[0034] Embodiment 1:
[0035] In this embodiment, a blinking device suitable for a robot is provided. The device is mainly installed on a pet robot, or a robot with other appearances, such as a human robot or a cartoon character robot, etc. The robot is equipped with a built-in blinking device, so that the robot has the function of blinking simultaneously.
[0036] like Figure 1 As shown, the blinking device suitable for the robot mainly includes an eyelid 2, a rotating shaft 3, a driving device 4, a reset spring 5, a driving device mounting seat 6 and an eyelid mounting seat 7.
[0037] The drive device mounting seat 6 includes a bottom plate 61 and two side plates 62 . The two side plates 62 are vertically fixed in the middle of the bottom plate 61 , and there is a preset distance between the two side plates 62 .
[0038] The eyelid 2 includes a left upper eyelid 21 and a right upper eyelid 22, which are rotatably mounted on a drive device mounting seat 6. Specifically, the eyelid mounting seat 7 includes a left eyelid mounting seat 71 and a right eyelid mounting seat 72, which are vertically fixed at both ends of the bottom plate 61, respectively. The left side of the left upper eyelid 21 is rotatably mounted on the left eyelid mounting seat 71 through a pin, and the right side of the right upper eyelid 21 is rotatably mounted on the right eyelid mounting seat 72 through a pin. The left upper eyelid 21 and the right upper eyelid 22 are connected together by a rotating shaft 3, and the rotating shaft 3 is rotatably mounted on two side plates 62. Finally, the left upper eyelid 21 and the right upper eyelid 22 form a rotatable structure. The rotating shaft 3 includes connecting parts 31 at both ends and a bending part 32 in the middle. The rotation centers of the connecting parts 31 at both ends are on a straight line. The bending part 32 can rotate around the connecting parts 31 at both ends. The bending part 32 forms a force arm that can drive the connecting part 31 to rotate, that is, the rotating shaft 3 is a crankshaft. The connecting parts 31 at both ends of the rotating shaft 3 are rotatably mounted on the two side plates 62, and are respectively connected to the right end of the left upper eyelid 21 and the left end of the right upper eyelid 22. The rotation of the rotating shaft 3 drives the left upper eyelid 21 and the right upper eyelid 22 to blink synchronously.
[0039] The driving device 4 includes a motor 41 and a cam 42. The motor 41 is a micro DC motor. The micro DC motor has the characteristics of small size, large output torque and easy control. It can be installed on a robot with a small size and can achieve blinking slowly and quickly. The motor 41 is installed on the base plate 61, and the cam 42 is installed on the output shaft of the motor 41. Under the drive of the motor 41, the cam 42 rotates periodically. The bending portion 32 of the rotating shaft 3 is located at the upper end of the cam 42, and the bending portion 32 always keeps in contact with the upper end of the cam 42 to form a contact connection. The cam 42 can drive the bending portion 32 to rotate periodically. In order to ensure that the bending portion 32 can always be in contact with the cam 42, the thickness of the cam 42 is greater than or equal to the distance moved by the bending portion 32 in the axial direction of the motor 41 during the swinging process, that is, when the robot is in a standing state, the bending portion 32 moves forward and backward during the up and down swinging process.
[0040] In order to make the bending part 32 have the ability to reset, a reset spring 5 is added. One end of the reset spring 5 is fixedly mounted on the side plate 62, and the other end is fixedly mounted on the bending part 32. The reset spring 5 is in a stretched state, so under the pulling force of the reset spring 5, the bending part 32 always keeps in contact with the cam 42. When the cam 42 drives the bending part 32 to swing upward, the reset spring 5 drives the bending part 32 to swing downward, realizing the up and down reciprocating swing of the bending part 32, and finally making the eyelid 2 blink up and down synchronously. In other embodiments, the reset spring 5 includes two, which are respectively arranged at both ends of the bending part 32, so that the bending part 32 has a more balanced restoring force and the swing of the bending part 32 is more stable.
[0041] The principle of synchronized blinking of the blinking device of the robot in this embodiment is as follows: the motor 41 drives the cam 42 to rotate, the cam 42 drives the bending part 32 to swing upward, the bending part 32 drives the connecting parts 31 at both ends to rotate simultaneously, and the connecting parts 31 at both ends drive the left upper eyelid 21 and the right upper eyelid 22 to rotate downward at the same time to achieve closing the eyes; then the cam 42 continues to rotate, the reset spring 5 drives the bending part 32 to swing downward, and the connecting parts 31 at both ends drive the left upper eyelid 21 and the right upper eyelid 22 to rotate upward at the same time to achieve opening the eyes. The combination of the above two actions, one closing and one opening, forms a blink, and it is set that the motor 41 drives the cam 4 to rotate one circle to complete a blink. The speed of blinking can be achieved by programming the control device, and the control device controls the voltage of the motor 41 to control the rotation speed of the motor 41 to achieve the frequency of blinking.
[0042] The present embodiment provides a blinking device suitable for a robot. The left upper eyelid 21 and the right upper eyelid 22 are connected together by a rotating shaft 3, and the rotating shaft 3 and the cam 42 are always kept in contact under the action of a reset spring 5, so that the rotating shaft 3 swings up and down along the outer contour of the cam under the drive of a motor, and finally drives the left upper eyelid 21 and the right upper eyelid 22 to blink at the same time. The robot with the blinking device is more lively, and the entertainment and bionics of the robot are increased.
[0043] Embodiment 2:
[0044] The blinking device suitable for a robot provided in this embodiment adds a lower eyelid on the basis of the above embodiment, and blinking is completed by rotating the upper and lower eyelids at the same time, making the blinking of the pet robot more vivid and dexterous.
[0045] like Figure 2 As shown, the eyelid 2 of a blinking device suitable for a robot provided in this embodiment also includes a left lower eyelid 23 and a right lower eyelid 24. In order to make the upper and lower eyelids rotate simultaneously, a left gear set 8 is provided between the left upper eyelid 21 and the left lower eyelid 23, and a right gear set (not shown in the figure) is provided between the right upper eyelid 22 and the right lower eyelid 24; the left gear set 8 includes an upper left gear and a lower left gear meshed together, and the right gear set includes an upper right gear and a lower right gear meshed together.
[0046] The left end of the left lower eyelid 23 is rotatably mounted on the left eyelid mounting seat 71 through a pin shaft, and the right end of the left lower eyelid 23 is rotatably mounted on the driving device mounting seat 6 through a pin shaft. The lower left gear is fixed on the pin shaft at the right end of the left lower eyelid 23, and the upper left gear is fixed on the connecting part 31 at the right end of the left upper eyelid 21. The upper left gear is meshed with the lower left gear up and down, and the upper left gear drives the lower left gear shaft, so that the upper left eyelid 21 and the lower left eyelid 23 rotate in opposite directions, thereby realizing the simultaneous closing and opening of the upper left eyelid 21 and the lower left eyelid 23.
[0047] The right end of the right lower eyelid 24 is rotatably mounted on the right eyelid mounting seat 72 through a pin shaft, and the left end of the right lower eyelid 24 is rotatably mounted on the driving device mounting seat 6 through a pin shaft. The right lower gear is fixed on the pin shaft at the left end of the right lower eyelid 24, and the right upper gear is fixed on the connecting part 31 at the left end of the right upper eyelid 22. That is, the right upper eyelid 22 and the right lower eyelid 24 rotate in opposite directions, and finally the four eyelids on the left and right sides blink up and down at the same time.
[0048] The present embodiment provides a blinking device suitable for a robot. Since the eyelids have left and right lower eyelids and left and right upper eyelids, and through the setting of left and right gear sets, the left and right gear sets drive the left and right lower eyelids and the left and right upper eyelids to rotate synchronously and blink, making the robot's blinking more vivid and dexterous.

The sensor device 10 is mounted on the head shell of the robot, and specifically, the sensor device 10 is mounted on the robot eye. Figure 3 As shown, the control device 9 is electrically connected to the motor 41 and the sensor device 10 respectively. The sensor device 10 is a microwave sensor or an infrared sensor, which is used to sense the movement within the field of view of the pet's eyes, and generates a sensing signal according to the sensing movement and sends it to the control device 9. The control device 9 controls the motor to rotate according to the sensing signal to achieve blinking. In other embodiments, the sensor device 10 is installed at other positions outside the robot's eyes to sense other movements outside the robot's field of view, thereby improving the robot's perception ability.
[0052] The blinking device of the present embodiment comprises a control device 9 and a sensor device 10. The blinking device can trigger the blinking device person to blink through gestures or other actions, thereby making the robot more intelligent and more humane.
[0053] Embodiment 4:
