Automobile instrument device capable of automatically calibrating and retaining instantaneous information by impact

Abstract

The invention discloses an automatic calibration and impact instantaneous information retention automobile instrument device, and the device comprises a working box body; a display cavity for displaying numerical values on the inner wall of the lower side is formed in the working box body, a glass panel is embedded in the upper end face of the working box body, a transmission cavity is formed in the working box body, and the transmission cavity is communicated with the display cavity. Zero adjustment correction is conducted on the speed instrument pointer of the automobile through the calibration device every time the automobile is shut down, display errors, caused by errors of a speed induction system, of the instrument pointer are avoided, instrument speed display accuracy is facilitated, and in addition, through inertia of collision accidents of the automobile, the device records the pointing speed value of a pointer in the speed instrument during an accident, and pushes out the instantaneous speed data, so that traffic processing personnel can know the speed data when the accident occurs, whether the vehicle speed meets the standard or not is judged, and then accident responsibility is divided.

Description

technical field [0001] The invention relates to the field of automobile instrument panels, in particular to an automobile instrument device which is automatically calibrated and retains instantaneous information upon impact. Background technique [0002] The instruments on the dashboard of different cars are not the same, but the conventional instruments of a general car include speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc. [0003] The most conspicuous thing in the instrument panel is the speedometer, which indicates the speed of the car. The basis for its display comes from the sensor. However, due to the error of the sensor, the speed pointer may deviate during long-term use, resulting in inaccurate speed indication. Secondly, modern When a car has a traffic accident on an unmonitored road section, the vehicle speed is unknown, which is not convenient for accident handlers to assign responsibilities. The present in...
