Embodiment

[0031] In the human eye simulation structure of this patent, there are three main simulation modules, such as figure 1 and figure 2 As shown, including simulated eyeball 2, eyelid 1, and pupil assembly 4;

[0032] The simulated eyelid assembly 1 is composed of simulated eyelids and fixed ears. The simulated eyelids are of a spherical structure. Two fixed ears are arranged at symmetrical positions on both sides of the simulated eyelids. The connecting position is provided with first and second through holes, and the first and second through holes are respectively connected with the shaft pins of the simulated eyeball assembly 2, and a third through hole is also provided on the fixed ear on the one side. The third through hole is connected with the connecting rod 17 through the connecting rod pivot pin.

[0033] The simulated eyeball component 2 is an integrated structure composed of simulated eyeball, eyeball pivot pin and eyeball support frame. These three parts are process...

Abstract

The invention relates to the technical field of human eye simulation, in particular to a medical human eye pupil and eyelid motion simulation structure and a control method thereof. The control method includes eyelid motion control and pupil motion control. The eyelid motion control includes: controlling an electromagnet shaft core to move telescopically through a circuit, and driving an eyelid simulation component to open and close by a connecting rod so that opening and closing of eyelids are realized. The pupil motion control includes: driving a motor shaft to rotate by a motor, then driving a shift shaft to rotate to drive a shift rod and a pupil control shaft to swing, and realizing pupil change by changing a bore diameter of a circular hole enclosed by inner arcs of aperture blades. The medical human eye pupil and eyelid motion simulation structure can successfully simulate motion ways of human eyes, complicated mechanical connection and control operation of existing human eye simulation are simplified, manufactured products are small in size and wide in application, and an anthropomorphic dummy can be more real and visual.

Description

[technical field] [0001] The invention relates to the technical field of human eye simulation, in particular to a structure for simulating human eye pupil and eyelid movement used in medical teaching and a control method for the structure. [Background technique] [0002] The simulated eyes used in medical teaching can allow medical learners to understand the pathological features reflected from the eyes more intuitively. The simulated eyes are the most important part of the simulated human head. Many pathologies can be detected by observing the eyes (mainly the pupils) size) to determine. [0003] At present, there are already many institutions at home and abroad that simulate human eyes, which are generally widely used in medical simulators, toys, and robots. Judging from the existing situation, some of them are completed by pasting the skin on the head frame, the eyelids cannot be blinked, and the pupils cannot be enlarged or shrunk; On the eyeball, eye opening and closi...
