Description

Technical Field

[0001] This utility model relates to the field of simulation robot technology, specifically a blinking transmission mechanism for simulation robots. Background Technology

[0002] In the field of simulation robots (such as service robots, bionic interactive robots, and film and television special effects robots), the degree of anthropomorphism of facial expressions is one of the core indicators for measuring their interactive experience and simulation effect. As one of the most basic and frequent dynamic expressions on the human face, the design of the transmission mechanism of "blinking" directly determines the naturalness, smoothness and simulation accuracy of the robot's eye movements.

[0003] Most blinking mechanisms in commercially available robotic simulators employ simple single-motor + linkage direct push or electromagnet attraction structures. The motor directly drives the eye cover to flip, resulting in a short transmission path and a lack of multi-stage buffering and adjustment. This leads to stiff blinking movements, uniform angular velocity without any change, and a significant difference between the simulation effect and a real human blink. While electromagnet-driven mechanisms have a fast response speed, the attraction force is difficult to control precisely, easily causing problems such as abnormal noises from the cover collision or incomplete closing angle. Therefore, it is necessary to design a blinking transmission mechanism for robotic simulators to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a blinking transmission mechanism for a simulated robot to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blinking transmission mechanism for a simulated robot, including a base plate, a fixing box at one top end of the base plate, an installation groove inside the fixing box, and a rotating rod connected to the mounting groove by a bearing inside the mounting groove, with both ends of the rotating rod extending to the outer side of the base plate respectively. A support frame is bolted to one end of the top of the base plate. Two sets of rotating shells are respectively connected to one side of the two sets of support frames by bearings. Movable components are connected between the two ends of the rotating rod and the four sets of rotating shells. A servo motor is provided at the bottom of the inside of the mounting slot. A transmission component is installed between the rotating rod and the servo motor.

[0006] Preferably, the movable component includes a turntable, a support rod, a support base, and a connector. The two sets of turntables are respectively connected to the two ends of the rotating rod located on the outside of the base plate. The two sets of support rods are respectively connected to one side of the two sets of turntables. The four sets of support bases are respectively installed on one side of the four sets of flip shells. The connector is movably connected between the two sets of support rods and the four sets of support bases.

[0007] Preferably, the connecting member includes a movable plate and a movable rod. The four sets of movable plates are rotatably connected to the outside of the two sets of support rods, and one end of the four sets of movable rods is connected to one side of each set of movable plates, while the other end of the movable rod is bearing-connected to the inside of each set of support seats.

[0008] Preferably, the transmission assembly includes a drive gear and a transmission gear. The drive gear is connected to the output end of the servo motor, and the transmission gear is installed at the middle end of the rotating rod, with the drive gear meshing with the transmission gear.

[0009] Preferably, two sets of support frames are installed at the bottom of the mounting slot, and the servo motor is installed on top of the two sets of support frames.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. By activating the servo motor to drive the transmission assembly, the transmission assembly drives the rotating rod to rotate within the mounting slot inside the fixed box. The rotating rod drives the turntables connected to both sides to move. The two turntables drive the support rods connected to one side to move, causing the two support rods to pull the movable plate connected to the outer side to move. The movable plate drives the movable rod to move, and the movable rod pulls the support base at the other end and the flip shell on one side of the support base to move. One end of the four flip shells is connected to one side of the two support frames by a bearing, realizing the semi-circular flip movement of the flip shells. Conversely, the servo motor reverses to push the flip shells to move in the opposite direction, thereby realizing the dynamic rhythm and angle changes of the human blinking when the bionic robot blinks.

[0011] 2. The servo motor drives the output end to rotate the drive gear. The drive gear meshes with the transmission gear installed on the outside of the rotating rod. When the servo motor is running, the rotating rod rotates in the mounting slot. Two sets of support frames installed inside the mounting slot support the servo motor, improving the stability of the servo motor during operation. The support frames can be removed to disassemble, inspect, and repair the servo motor. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1: Please refer to Figure 1-3 As shown, this utility model provides a blinking transmission mechanism for a simulation robot, including a base plate 1, a fixing box 2 at one end of the top of the base plate 1, an installation groove 3 inside the fixing box 2, a rotating rod 4 connected to the bearing inside the installation groove 3, and the two ends of the rotating rod 4 extending to the outside of the base plate 1 respectively. A support frame 7 is bolted to one end of the top of the base plate 1. Two sets of rotating shells 8 are respectively connected to one side of the two sets of support frames 7 by bearings. Movable components are connected between the two ends of the rotating rod 4 and the four sets of rotating shells 8. A servo motor 5 is provided at the bottom of the inside of the mounting groove 3. A transmission component is installed between the rotating rod 4 and the servo motor 5.

[0016] Specifically, by activating the servo motor 5 to drive the transmission component, the transmission component drives the rotating rod 4 to rotate within the mounting slot 3 inside the fixed box 2. The rotation of the rotating rod 4 pulls the movable component between it and the flip shell 8, and the movable component pulls the four sets of flip shells 8 to move. One end of the four sets of flip shells 8 is connected to one side of the two sets of support frames 7 by a bearing, realizing the semi-circular flipping movement of the flip shells 8. Conversely, the servo motor 5 reverses and pushes the flip shells 8 to move in the opposite direction, thereby realizing the dynamic rhythm and angle changes of the bionic robot simulating the blinking of a human.

[0017] The movable components include turntables 6, support rods 9, support seats 12, and connectors. Two sets of turntables 6 are respectively connected to the two ends of the rotating rod 4 located on the outside of the base plate 1. Two sets of support rods 9 are respectively connected to one side of the two sets of turntables 6. Four sets of support seats 12 are respectively installed on one side of the four sets of flip shells 8. The connectors are movably connected between the two sets of support rods 9 and the four sets of support seats 12. The rotating rod 4 drives the turntables 6 connected on both sides to move. The two sets of turntables 6 drive the support rods 9 connected on one side to move, so that the two sets of support rods 9 pull the connectors. The connectors drive the four sets of support seats 12 connected to the bearings on the other end to move, so that the four sets of support seats 12 pull the flip shells 8 to move.

[0018] The connecting parts include movable plates 10 and movable rods 11. Four sets of movable plates 10 are rotatably connected to the outside of two sets of support rods 9. One end of each set of movable rods 11 is connected to one side of each set of movable plates 10, and the other end of the movable rods 11 is connected to the inside of each set of support seats 12 by a bearing. The movement of the support rods 9 pulls the movable plates 10 rotatably connected to the outside to move. The movable plates 10 drive the movable rods 11 to move. The movable rods 11 pull the support seats 12 at the other end and the flip shell 8 on one side of the support seats 12 to move.

[0019] The transmission assembly includes a drive gear 13 and a transmission gear 14. The drive gear 13 is connected to the output end of the servo motor 5, and the transmission gear 14 is installed at the middle end of the rotating rod 4. The drive gear 13 and the transmission gear 14 mesh with each other. The servo motor 5 drives the output end to rotate the drive gear 13. The drive gear 13 meshes with the transmission gear 14 installed on the outside of the rotating rod 4. When the servo motor 5 is running, the rotating rod 4 rotates in the mounting groove 3.

[0020] The mounting slot 3 has two sets of support frames 15 installed at its bottom. The servo motor 5 is mounted on top of the two sets of support frames 15. The two sets of support frames 15 installed inside the mounting slot 3 support the servo motor 5, thereby improving the stability of the servo motor 5 during operation.

[0021] Working Principle: This utility model provides a blinking transmission mechanism for a simulated robot. When in use, the servo motor 5 is turned on, driving the output end to rotate the active gear 13. The active gear 13 meshes with the transmission gear 14 installed on the outside of the rotating rod 4. When the servo motor 5 is running, the rotating rod 4 rotates in the mounting groove 3, driving the turntables 6 connected on both sides to move. The two sets of turntables 6 respectively drive the support rods 9 connected on one side to move, causing the two sets of support rods 9 to pull the movable plate 10 connected to the outside to move. The movable plate 10 drives the movable rod 11 to move, and the movable rod 11 pulls the support seat 12 at the other end and the flip shell 8 on one side of the support seat 12 to move. One end of the four sets of flip shells 8 is connected to one side of the two sets of support frames 7 by bearings, realizing the semi-circular flipping movement of the flip shells 8. Conversely, the servo motor 5 reverses and pushes the flip shells 8 to move in the opposite direction, thereby realizing the dynamic rhythm and angle change of the human blinking when the bionic robot is simulated.
