Abstract
The utility model relates to a simple vehicle-mounted acceleration measurement instrument, and is characterized in that the acceleration measurement instrument comprises a shell, a mass block and a leaf spring; an empty groove is arranged in the shell, the mass block is hung in the empty groove through the leaf spring, the length of the mass block is smaller than that of the empty groove, and the mass block can swing leftwards and rightwards in the empty groove; fixed polar plates are arranged at a left end and a right end of an inner wall of the empty groove, and are separated from the shell by an insulator; the mass block can contact with the fixed polar plates to generate a signal while swinging leftwards and rightwards; the fixed polar plates at the left end and the right end in the empty groove and the shell contact with a transmission line respectively to be connected to an input end of a signal amplification device, the signal amplification device is connected to a control chip, and an output end of the control chip is connected to a display screen. The simple vehicle acceleration measurement instrument is simple and skillful in structure, and low in cost, can accurately detect acceleration of an automobile in running, and is convenient for a driver to clearly know the speed of the automobile in running.
Description
Technical field
The utility model relates to a kind of daily living article, specifically a kind of easy vehicle-mounted accelerograph.
Background technology
Now a lot of automobiles all have the Intelligent speed-measuring device, can detect accurately the travel speed of automobile, are convenient to the driver and clearly understand.But this installation cost is higher, and some is kept out automobile and can't install.And this device can not clearly detect the amplitude of automobile acceleration or deceleration.
The utility model content
For above-mentioned situation, the utility model discloses a kind of easy vehicle-mounted accelerograph, its cost is low, on various types of automobiles, can detect accurately the acceleration of running car.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of easy vehicle-mounted accelerograph, it is characterized in that, comprise housing, mass and spring leaf, be provided with dead slot in described housing, mass is unsettled in dead slot by spring leaf, the length of its Length Ratio dead slot is short, and mass can swing in dead slot; The two ends, inwall left and right of dead slot are provided with fixed plate, and fixed plate separates by insulator and housing; When swinging, mass can contact and produce with fixed plate signal.
The fixed plate at the two ends, left and right in dead slot and housing contact respectively a transmission line and are connected with the input end of signal amplifying apparatus, and signal amplifying apparatus is connected with control chip, and the output terminal of control chip is connected with display screen.
The beneficial effects of the utility model are: its simple and ingenious structure, and with low cost, can detect accurately the acceleration of running car, be convenient to the speed conditions that the driver clearly understands running car.
