Abstract

The utility model discloses an apparatus for measuring distance travelled by vehicles, which is composed of a small magnetic block which is fixed on a wheel spoke of a vehicle wheel, a magnetic induction switch which is fixed on a vehicle bodyb and an electronic pedometer which is connected with the magnetic induction switch. The utility model has the advantages of simple structure, easy fabrication, low cost, reliable use effect and high measuring accuracy.

Description

Apparatus for measuring distance traversed by vehicles

It is feature that the utility model relates to a kind of method with magnetic and electricity, metering vehicle range ability, the device of the move distance when particularly measuring cycling.It is made of the motion sensor and the signal Processing display that are installed on the vehicle.

China's utility model patent 88204891.0 discloses a kind of device that measures the cycling distance, it is to constitute motion sensor by being installed in the magnetic block on the wheel spoke and being fixed on the vehicle frame with the corresponding tongue tube in magnetic block installation site, and the tongue tube lead-in wire equals' key with electronic calculator joined, with electronic calculator as signal Processing and display.This patent is because need adopt counter, so manufacturing cost is higher, is unsuitable for basically using on bicycle; Secondly, need when adopting this patent before metering, to preestablish additive operation and addend, and this " computing " pattern can't be got rid of the interference of other operational pattern.When the device that uses this patent disclosure measures, be touched (in fact this situation is difficult to avoid) again as other keys of counter, will produce wrong data.

The purpose of this utility model provides a kind of with low cost, can not cause measuring wrong vehicle operating distance measuring device because of misoperation in the metering.

The utility model is formed sensor with magnetic block and tongue tube, as signal Processing and display device, constitutes measuring apparatus with electronic pedometer.

Accompanying drawing provides a kind of embodiment of the present utility model.

Fig. 1 is structural representation.

Fig. 2 is a wiring diagram.

Below in conjunction with accompanying drawing the utility model is made detailed explanation.

Form sensor by being fixed on permanent magnet " 1 " on the bike spoke " 4 " voluntarily and the tongue tube " 2 " that is fixed on the front fork " 3 " among Fig. 1." 5 " are electronic pedometer.Adopted trade mark to be in the present embodiment: the electronic pedometer of " INNOVATIVE TIME ".The lead at tongue tube two ends is joined with the counting input end of passometer and the positive pole of battery respectively, and the data of being measured show on the display screen of passometer.When wheel whenever circles, tongue tube connected once by the magnet adhesive, the count pulse of generation is sent in the microprocessor of electronic pedometer and is added up.

Fig. 2 is a kind of best mode of connection, and two lead-in wires of tongue tube are received on two core plugs " 6 "." 7,8,9 " are respectively three leading-out terminals of socket." 7 " are connected with the signal input part of passometer, and " 8 " are connected with the weight " 10 " of passometer, and " 9 " are connected with anode." 7,8 " 2 connections when plug is extracted, passometer can normally use, and all functions are constant.When plug inserts, " 7,8 " 2 disconnections, " 7,9 " are connected with the tongue tube two ends respectively, enter the vehicle state of having the records of distance by the log.When vehicle moves because of the vibrations weight, can therefore not produce miscount, use accurately reliable.

Only need during the utility model uses the stride shelves of passometer are transferred to the shelves that equate with wheel circumference, function is transferred to the distance display shelves gets final product.With 28 cun bicycles is example, in the application stride is transferred to " 223.43cm " shelves, and function places the distance display shelves, can measure and show.

The utility model advantage:

1. install simple, with low cost, market real price according to investigations, the price of electronic pedometer is lower than about 10 yuan of ordinary electronic calculators at least.

2. the utility model does not produce the mistake metering, particularly will can not produce the problem of mistake metering with the sort of passometer that adopts among the embodiment.This is to pick up more than second at number because of function of passometer by using adjustment or stride adjustment all need the hand touching, but also moving other key that need press...with one's finger just can be adjusted.Therefore except that artificial adjustment, can't produce misoperation.

3. measuring accuracy height, the length of having the records of distance by the log are example with embodiment: because this passometer is to adopt floating-point to show that its distance display scope is at 30 centimetres-999999 kilometers.

4. the many usefulness of a device can be counted distance, can count the step again, also can be used as in time showing and the industrial and agricultural production purposes such as product counting.

Claims

Vehicle, the measuring apparatus of particularly cycling distance, constitute by the motion sensor and the signal Processing display that are installed on the vehicle, wherein motion sensor is to be installed on the magnetic block that the permanent magnetic material on the wheel spoke makes and to be fixed on the car body with on the spoke the corresponding tongue tube in magnetic block position is installed, it is characterized in that the signal Processing display is an electronic pedometer, the count signal input end of the lead-in wire of tongue tube and electronic pedometer joins.
