Vehicle window glass automatic switching physical demonstration device and vehicle window glass automatic switching physical demonstration method

Abstract

The invention discloses a vehicle window glass automatic switching physical demonstration device and a vehicle window glass automatic switching physical demonstration method, and belongs to the physical experimental apparatus field. The vehicle window glass automatic switching physical demonstration device is mainly constituted by a temperature control switch, a window opening position controller, a storage battery, a direct current motor, a circuit switch rotating disc, an elastic switch, a magnet, a vehicle window glass elevating rack, and a piece of vehicle window glass. By reconstructing a glass syringe, a function of realizing temperature control over the turning of the direct current motor is provided, and a function of realizing the temperature control over the opening range limitation of the vehicle window glass is provided. The vehicle window glass is opened automatically for ventilation and cooling in high temperature environment in an unmanned parking flameout state, and the vehicle window glass is closed automatically in low temperature environment, and therefore casualties and fire hazards in the vehicle are effectively prevented. The above mentioned demonstration device and the above mentioned demonstration method are used for teaching, and then students are effectively cultivated to use local materials and learned physical knowledge to carry out creative training, and therefore obvious novelty, practicability, and creativity are provided, production is easy, a structure is concise, effect is obvious, and more teaching functions are provided for classroom teaching.

Description

technical field [0001] The patent of the invention relates to a physical demonstration device and method for demonstrating automatic opening and closing of vehicle window glass, and belongs to the technical field of physical experiment instruments and automobile window opening. Background technique [0002] Based on social progress and the continuous development of science and technology, the application of automobiles is becoming more and more common, and safety hazards have emerged. This phenomenon has attracted enough attention. In 2013, major media scrambled to report "car spontaneous combustion" and "car explosion" etc. The accident, accompanied by the tragic case of a child being suffocated in the car, the weather is getting hotter and hotter, and the temperature in the car is also extremely high in summer, because the tragedies caused by this high temperature are also emerging in endlessly. In June 2015, a 4-year-old boy in Hunan was locked in a car and died. When he ...
