APPARATUS FOR SENSING IMPACT AND VARIATION OF VELOCITY

摘要

An apparatus for sensing impact and velocity variation is provided to detect the impact applied to a car by moving a sensing wheel correspondingly to the impact. A lower cover(100) has a bottom surface part(110) which has a flat surface. A sensing wheel support frame(200) has a rectangular frame structure(210) and is coupled to the lower cover. An upper cover(300) includes a ceiling unit(310) covering the sensing wheel support frame and is coupled to the lower cover and the sensing wheel support frame. A touch screen panel(400) is formed on the bottom surface unit of the lower cover. First and second sliding bars(510,520) are formed from one surface inside the sensing wheel support frame to the other surface opposite to the one surface so as to be parallel with each other. A sensing slider(600) is inserted and coupled into the first and second sliding bars and moved along the first and second sliding bars by inertial force. A sensing wheel(700) is moved on the touch screen panel through the inertial force by coming in contact with the touch screen panel. First to fourth elastic springs are inserted into the first and second sliding bars with respect to the sensing slider. A connector(CON) outputs a signal detected by the touch screen panel according to contact with the sensing wheel.
