This creation is about teaching aids for inverse piezoelectric effect simulation. It is mainly used to help students to understand the reverse piezoelectric effect and to design auxiliary teaching aids. With the simplest structural design and operation, supplemented by LED light changes and elasticity. The expansion and contraction of the cloth sleeve enables the students to clearly recognize the inverse piezoelectric effect and achieve the benefits of teaching with half the effort.

According to the teaching method of textbooks, it is not only easy for students to feel dull, but also effective in understanding and absorbing. In particular, it is difficult to understand the science and engineering. Without practical operation or experiment, it is very difficult. Let the students understand and understand the content of the lecture with the imagination of the imagination. In terms of the inverse piezoelectric effect of the original target, after applying a voltage (force) on the surface of the piezoelectric material, the electric coupling pole moment will be elongated due to the electric field. However, in order to resist this change, the piezoelectric material will elongate in the direction of the electric field to form an effect of converting electrical energy into mechanical energy. However, due to the lack of specificity of the seed effect, most students are not able to operate and explain with the aid of teaching aids. It is impossible to understand and understand the substance of the inverse piezoelectric effect.

In order to solve the problem of the inverse piezoelectric effect in teaching, It is the development of a new patent case of the "Inverse Piezoelectric Simulation Teaching Device" No. M474999. The teaching device is mainly composed of a base, a handle, a transmission unit, a power generation module, a battery, and a battery. a light-emitting module, a displacement module, a charging module and a deformation module, the handle is attached to the base and coupled with the transmission wheel unit disposed on the base, and driven by the handle The power transmission module of the transmission base unit is operated to generate electric power, and the generated electric power is stored in the battery on one side of the base, and the battery is electrically charged with another illumination module on the base. The connection is made to enable the illumination module to emit light, and the transmission wheel unit is further connected with the displacement module, so that the displacement module is controlled by the transmission wheel unit to perform a linear reciprocating motion, and at the same time, the charging and suction module is repeatedly reversed. Inflating and inhaling, thereby forcing deformation of the elastic cylinder of the deformation module on one side of the base, thereby simulating the deformation state of the piezoelectric material in the inverse piezoelectric effect, thereby contributing to the student's more realistic recognition Piezoelectric effect.

However, the above-mentioned teaching device can achieve the function of simulating the inverse piezoelectric effect through the action of the light-emitting module and the deformation module, but the overall structure is quite complicated, and the operation is troublesome and inconvenient, and the transmission module is transmitted through the displacement module. In order to control the inflation and inhalation of the inhalation module, and then the charging and inhaling of the inhalation module to control the deformation of the deformation module to form a multi-level indirect actuation mode, the lack of accuracy in the action and Smoothness and high failure rate are difficult to call the ideal and perfect design, and the necessity of self-improvement.

In view of the conventional teaching device for the simulation of the inverse piezoelectric effect In the absence of many complicated structures, difficult operation, lack of accuracy and smoothness of the movement, the creators have specially developed R&D and designed to provide more streamlined and practical teaching aids.

In order to solve the problems and shortcomings of the conventional teaching device, the creation is designed to directly operate the power module rotation with a rocker to make a magnetic field cutting effect with the magnet, and to trigger a programmable controller on one side ( PLC) (PLC), through which the programmable controller (PLC) drives the motor on one side and a set of LED modules, so that the LED module generates corresponding light changes, and at the same time, the motor spindle is provided. The slider of the cam push-up deformation module controls the top plate and the bottom plate to generate a tensioning action, so that the elastic cloth sleeve stretched between the top plate and the bottom plate has a visual effect of stretching and contraction, so as to achieve a simulated inverse piezoelectric effect. The function of the person.

The teaching aids of the inverse piezoelectric effect simulation of this creation are designed according to the structure, so that it can directly trigger the programmable controller (PLC) through the power generation module, and then synchronously drive the LED module and the motor to achieve a more direct back pressure. The electric effect simulation can not only achieve a large simplification in the overall structure, but also achieve specific improvements in operation and operation. In addition, the programmable controller (PLC) can be designed to make it instantaneous with the speed of the power generation module. In response to the change of the light of the LED module and the elastic cover of the deformation module, in addition to the simulation function of the inverse piezoelectric effect, the effect of the inverse piezoelectric size on the piezoelectric material can be simultaneously displayed, thereby giving better practical value.
