Signals to the processing unit 35. The plug-in unit 33 includes a conductive terminal 331 and a transmission line 33 electrically connected between the conductive terminal 331 and the conversion unit 34. The conductive terminal 331 is cooperatively inserted into the cigarette lighter 21, and is mainly used for A DC power signal generated by a generator (not shown) of the automobile engine and output via the cigarette lighter 21 is transmitted to the conversion unit 34. 7!271336_ The conversion unit 34 includes a conversion circuit 341 electrically connected between the conductive terminal 33 and the processing unit 35 and having a plurality of actuation programs built therein, and is electrically connected to the conversion circuit 341 and embedded in the casing 31. A multi-stage type: knife change switch 342 and a school adjustment button 343. In this embodiment, the current generated by the generator is directly affected by the speed of the engine. The engine speed is controlled by the number of ignitions of the car 2 (not shown). The faster the cylinder is fired. The faster the engine speed is, the transmission relationship will cause the AC power generated by the generator to be rectified by AC to DC, and then transmitted to the DC output of the cigarette lighter 21 to generate a different frequency/wave signal. The higher the engine speed, the higher the chopping signal frequency, and the lower the chopping signal frequency. The conversion circuit 341 can filter the DC power signal from the conductive terminal 33 and use it as a power source for driving the speed measuring unit 32, the processing unit and the display unit 36, and output the cigarette lighter 21.

In this embodiment, the display mechanism Between the 361 and the processing unit 35, data transmission is performed through a signal line 37. However, in the implementation, the data transmission between the display unit 361 and the processing unit 35 can also be designed to reduce the transmission type, such as infrared transmission or blue transmission, but It is worth mentioning that the car is equipped with the speed detecting device for the first time, or it is detached from the originally assembled car 2, and when it is assembled in another car 2, there is L in the mother. The number of cylinders of -2 will cause the engine speed to differ from the frequency of the chopping signal in the output DC. In order to make the engine speed value represented by the projected image 360 correct, after the assembly is completed, the user can First, the switch 342 of the conversion unit it 34 is triggered corresponding to the number of cylinders of the car 2, and the corresponding program built in the conversion circuit 341 is activated, and then 'the engine is started and the car is empty. In the gear state, by stepping on the throttle map (not shown), „turning the 7th adjustment button 343, fine-tuning the conversion circuit Μ丄 output to the signal of processing the early 35, until the display mechanism 361 projects the formed image 360 towel engine speed The value is roughly equal to the engine speed value on the instrument panel (not shown), which is quite convenient. In addition, when the θ-hai vehicle speed detecting device is implemented, it can also be designed to be electrically connected to a 1-star signal gainer (not shown), so that the speed can be transmitted through the gain when the satellite ring number is poorly received. Therefore, the unit 32I can receive the satellite signal more clearly, but the implementation is not limited to this. 10 1271336 As shown in FIG. 2 and FIG. 4, the second comparison of the vehicle speed detecting device of the present invention is shown. The preferred embodiment is substantially the same as the first embodiment, except that the display mechanism 361 is assembled in the casing 31 and partially exposed to the casing, and can be projected on the front windshield 22 The image sensor 36 and the brightness adjustment button 364 of the brightness adjustment mechanism 362 are respectively embedded and exposed on the casing 31. When the speed measuring device is used, the box body 3 is directly disposed on the windshield 22 in front of the driver's seat, so that the display unit % can project on the windshield 22 to form the image 36〇, and provide the driver's speed and speed information. . In summary, the speed detecting device of the vehicle only needs to electrically connect the conductive terminal 331 of the plug-in unit 33 to the cigarette lighter 21, and the speed of the vehicle can be measured through the speed measuring unit το 32, and the vehicle speed is utilized. The conversion unit 34 directly obtains the design of the engine speed from the electrical signal of the cigarette lighter 21, so that the assembly and use of the vehicle speed detecting device is more convenient, and the display unit is connected to the processing unit 35 through the signal line 37. After the line, the display mechanism 361 can be projected only by placing it in an appropriate position, so that the user can assemble it by hand and can be easily removed and moved to other cars. In addition, the display unit 36 can directly project data such as current vehicle speed and engine speed on the front windshield 22 at the driver's horizontal viewing angle, so that the user can know the current speed without having to shift the line of sight. Engine speed is quite helpful for improving driving safety. Therefore, the object of the present invention can be achieved. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent of the scope of the invention and the description of the invention according to the present invention. Variations and modifications are still within the scope of the invention. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view of a vehicle speed detecting device mounted on a vehicle;
