Abstract

An improved over-running indicator structure essentially comprises an upper housing, a lower housing, a circuit board and a fixing support; the upper housing and the lower housing are firmly connected by a lock device, and the lower housing is fixed on the fixing support; a circuit board is set between the upper housing and the lower housing, the circuit board is configured with a light emitter, a screen and a button, the circuit board uses a transmission line to connect with a tachometer; a driver can use the button to set the rotational speed for showing the rotational speed which is set by the driver on the screen, when the rotational speed of the engine exceeds the rotational speed that is set by the driver, the light emitter disposed on the circuit board shines and radiates the light thereof through the arc surface of the upper housing, thus, the driver feel no constrained to any angle for being readily aware of the optimal shifting time to acquire the best power from engine.

Claims

1. An over-running indicator structure for an automobile comprising:

an upper housing substantially hemispherical in shape and light-transmissive, with a bottom of said upper housing being provided with at least a pair of thread holes adapted to reversibly receive a bottom screw therein;

a lower housing, with an inner surface of said lower housing being formed with a plurality of hollow threaded ribs in close proximity to a rim of said lower housing, the inner surface of said hollow threaded rib being formed with a screw thread adapted to reversibly receive a top screw therein, the rim of said lower housing further being configured with a screw hole;

a pair of mounting legs in fixed continuity with and extending downward from the bottom of said lower housing, each of said mounting leas formed with a mounting hole therethrough;

a circuit board with a plurality of board holes disposed along an outer perimeter and fixedly seated on said lower housing so that said screw holes align with said hollow thread ribs of said lower housing, said circuit board further provided with a light emitter, a data screen and a plurality of control buttons, and adapted to connect to an electronic data transmission cable, wherein the circuit board is fixedly seated in the lower housing adjacent the rim by a plurality of top screws being rotatingly advanced through the board holes and respectively into said plurality of hollow threaded ribs, said upper housing and lower housing being firmly connected to each other by rotatingly advancing at least a pair of bottom screws through the screw holes on the rim of said lower housing and into the respective thread holes of the upper housing;

a mounting support provided in a preferred embodiment with a plurality of base through holes;

a pair of mounting brackets formed on said mounting support and extending upward therefrom to juxtapose respectively with the corresponding pair of mounting legs so as to alien the pair of mounting holes respectively with a pair of axle hole formed through said mounting brackets, said paired axle holes and paired mounting holes adapted to reversibly accept a bolt-like axle therethrough, thereby connecting said lower housing and said mounting support, wherein a user rotates the lower housing with respect to the mounting support and tightens said bolt-like axle to fixedly maintain a chosen configuration of said over-running indicator structure.

3. The over-running indicator structure according to claim 1, wherein said circuit board further comprises at least one color changeable light emitter.
