Abstract
The utility model relates to a speed and mileage recorder of bicycles, having an electronic computation displayer, a light source, and a light sensitive element, which are electrically connected, wherein, the light source and the light sensitive element are respectively arranged on both sides of a bicycle fork, and the spokes of the wheel is fixed with a light screen. When the utility model collects the rotating parameters of the wheel, no mechanical contact and no wear exists, and the physical load of the rider can be increased; the service life is long, and the measure is accurate.
Description
The utility model relates to meter speed, the log arrangement of bicycle.
Occurred a kind of bicycle meter speed, log arrangement on the market, it has a steamboat to be contained in car to stick, and steamboat rotates near wheel thereupon.The rotation number of turns of steamboat is converted into electric signal and is passed on electronics calculating, the display.Calculate, display has button can import parameters such as radius of wheel, so that its accurately response speed and mileage.Owing to use the friction of steamboat and wheel to gather rotational parameters, increased bicyclist's physical load, and mechanical wear influences its serviceable life greatly.
The purpose of the utility model is to provide a kind ofly not increase bicyclist's physical load, and does not have bicycle meter speed, the taximeter of wearing and tearing.
Described bicycle meter speed, taximeter, it is prior art that electronics calculating, display are arranged, car is pitched a side light source is housed, the car fork opposite side corresponding with light source is equipped with light activated element, fix a shadow shield on the wheel width of cloth bar between light source and the light activated element, light source and light activated element calculate with electronics respectively, display is electrically connected.
Use described bicycle meter speed, taximeter, the moving circle of wheel revolution blocks light source once, and electric signal of light activated element output is given and calculated, display, to show the speed of a motor vehicle and mileage.This meter speed, taximeter do not have the machinery contact, do not have wearing and tearing when gathering the commentaries on classics parameter, physical load, the life-span that can not increase the bicyclist are long, and accurate measurement.
Fig. 1, the scheme of installation of described meter speed, taximeter.
Fig. 2 is the side view of Fig. 1.
Light source 2 is light emitting diode or small spotlight bubble, is contained in car and pitches 4 one sides.The car corresponding with light source 2 pitched 4 opposite sides light activated element 1 is housed, and light activated element is photodiode or photoresistance.Fixing shadow shield 3 on the wheel width of cloth bar between light source 2 and the light activated element 1.Electronics calculates, display 5 is contained on the handlebar, is electrically connected with light source 2 and light activated element 1.
Claims (3)
1, a kind of bicycle meter speed, taximeter, electronics calculating, display (5) are arranged, it is characterized in that, car fork (4) one sides are equipped with light source (2), car fork (4) opposite side corresponding with light source (2) is equipped with light activated element (1), fix a shadow shield (3) on the wheel width of cloth bar between light source (2) and the light activated element (1), light source (2) and light activated element (1) calculate with electronics respectively, display (4) is electrically connected.
By the described bicycle speed of claim 1, taximeter, it is characterized in that 2, light source (2) is light emitting diode or small spotlight bubble.
By the described bicycle speed of claim 1, taximeter, it is characterized in that 3, light activated element (1) is photodiode or photoresistance.
