Description

Technical Field

[0001] This utility model relates to the field of bionic robot technology, and in particular to an upper eyelid driving component and a bionic robot head. Background Technology

[0002] Robotics technology has developed rapidly alongside the advancement of modern science and technology, and robots are becoming increasingly capable, gradually approaching human capabilities. As robots evolve, the gap between them and humans will narrow, making biomimetic robots one of the latest research directions in the field of robotics. They can achieve effective human-machine interaction, enabling natural, harmonious, and friendly communication between humans and machines, reducing the emotional distance between them, and thus satisfying both human material needs and emotional needs.

[0003] Currently, the driving mechanism for the eyes of bionic robots is generally achieved by connecting the upper eyelid with a string. Pulling the string tightens it, causing the upper eyelid to move upward, while slackening it allows the upper eyelid to fall automatically. However, this driving method results in unstable upper eyelid movement, leading to unrealistic facial expressions. Utility Model Content

[0004] The purpose of this invention is to provide an upper eyelid driving component and a bionic robot head to solve the technical problem that the existing wire-driven driving method causes unstable upper eyelid movement, resulting in unrealistic facial expressions.

[0005] In a first aspect, this utility model provides an upper eyelid driving component, which is disposed on the head of a bionic robot and is used to drive the skin movement of the upper eyelid. The upper eyelid driving component includes: an upper eyelid actuator, an upper eyelid traction frame, and an upper eyelid traction member.

[0006] The bionic robot head is equipped with an eye support, and the upper eyelid actuator is mounted on the eye support and is connected to the upper eyelid traction frame.

[0007] The upper eyelid traction frame is bow-shaped and is used to be mounted on the eyeball. Both ends of the upper eyelid traction frame are rotatably connected to the eye support so that the upper eyelid traction frame can rotate back and forth around the eyeball.

[0008] The upper eyelid traction device is connected to the upper eyelid traction frame and is used to connect with the skin of the upper eyelid.

[0009] In an optional embodiment, the upper eyelid traction frame is provided with a magnet, and the upper eyelid frame is connected to the upper eyelid traction member through the magnet.

[0010] In an optional embodiment, the upper eyelid traction frame is provided with a magnet mounting groove, and the opening of the magnet mounting groove faces forward.

[0011] The magnet is disposed in the magnet mounting slot.

[0012] In an optional embodiment, the magnet mounting slot is located in the middle of the upper eyelid traction frame.

[0013] In an optional implementation, an upper eyelid rocker arm is also included;

[0014] The output end of the upper eyelid actuator is connected to the upper eyelid rocker arm, and the upper eyelid rocker arm is driven to be connected to the upper eyelid traction frame.

[0015] In an optional implementation, an upper eyelid link is also included;

[0016] The upper eyelid rocker arm is connected to the upper eyelid traction frame via the upper eyelid linkage.

[0017] In an optional embodiment, the upper eyelid connecting rod is provided with a perforated hole.

[0018] In an optional embodiment, the upper eyelid link is connected to the wall of the magnet mounting slot.

[0019] In an optional embodiment, both ends of the upper eyelid connecting rod are provided with plug bolts;

[0020] The two ends of the upper eyelid connecting rod are respectively connected to the upper eyelid rocker arm and the upper eyelid traction frame via the plug bolts.

[0021] Secondly, this utility model provides a bionic robot head, including the upper eyelid driving component described in any of the foregoing embodiments.

[0022] Compared with the prior art, the technical advantages of the upper eyelid driving component and the bionic robot head provided by this utility model are as follows:

[0023] The upper eyelid driving assembly provided by this utility model is disposed on the head of a bionic robot and is used to drive the movement of the skin in the upper eyelid area. The upper eyelid driving assembly includes: an upper eyelid driver, an upper eyelid traction frame, and an upper eyelid traction component. The bionic robot head is provided with an eye support, the upper eyelid driver is disposed on the eye support and is connected to the upper eyelid traction frame for transmission. The upper eyelid traction frame is bow-shaped and is used to be mounted on the eyeball. Both ends of the upper eyelid traction frame are rotatably connected to the eye support so that the upper eyelid traction frame can rotate back and forth around the eyeball. The upper eyelid traction component is connected to the upper eyelid traction frame and is used to connect with the skin in the upper eyelid area.

[0024] Because the upper eyelid traction frame is arched and placed on the eyeball, with the eyeball located inside the frame, when the upper eyelid traction frame is rotated on the eye support by the upper eyelid actuator, it can rotate back and forth around the eyeball, avoiding interference with the eyeball. At the same time, the rotation of the upper eyelid traction frame can drive the upper eyelid traction component connected to the skin of the upper eyelid to move, so that the skin of the upper eyelid moves together, ensuring the stability of the skin movement of the upper eyelid, thus making the expression more realistic.

[0025] The bionic robot head provided by this utility model includes the above-mentioned upper eyelid driving component. Therefore, the technical advantages and effects achieved by it include the technical advantages and effects achieved by the above-mentioned upper eyelid driving component, which will not be described in detail here.
