Abstract
A motorcycle electromagnetic induction type odometer is characterized in that: a magnet capable of rotating with a wheel is arranged on a wheel shaft, a sensor which is provided with an induction magnet and does not rotate with the wheel is arranged on the outside of the magnet, the sensor is connected with a counting chip through a circuit, and the counting chip is connected with a display device through the circuit. The display device can be a pointer type display device or a digital type display device. The utility model can obtain relative data without gear drive with correct information, thereby greatly reducing the mean time between failures of the odometer; the utility model adopts the electromagnetic induction type speed measurement without affecting the rotation of the wheel, thereby effectively avoiding the problem that: a mechanical type odometer produces a drag force on the rotation of the wheel.
Description
Technical field
The utility model relates to the mileage display device of motor vehicle, the induction mileometer of concrete a kind of motor automobile of design.
Background technology
Traditional mechanical type mileometer generally all is that the wheel shaft of wheel is provided with odometer drive, driving mechanism is generally ratio wheel, after ratio wheel slows down, be transferred to gauge outfit by flexible axle, through gear reduction, again by number wheel rolling counters forward, finish the measurement of mileage, this mechanical type mileometer complex structure, member is various, and with high costs; Partial component need run up when testing the speed, and after a period of time, often produces fault because of the infiltration of foreign object or dirt, aqueous vapor etc. or because of wearing and tearing make it, thereby needs often maintenance.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of motor automobile induction mileometer.
In order to address the above problem the technical solution of the utility model is such:
The induction mileometer of a kind of motor automobile, it is characterized in that, axletree is provided with the magnet that rotates with wheel, the outside of magnet has the sensor that does not rotate with wheel of induced magnet, described sensor connects a computing chip by circuit, and computing chip connects a display device by circuit.
Described display device is a dial indicator display device.
Described display device is a digital type display device.
Beneficial effect, the utility model can be responded to actual running speed, and change accordingly, by circuit signal are passed to display device, the related data of vehicle ' that made the direct perception of people.Need not to obtain related data through gear drive, data is accurate, and the mileometer mean time between failures reduces greatly, and induction testing the speed do not influence wheel, effectively avoids the mechanical type mileometer, wheel is produced the problem of resistance.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of the induction mileometer of a kind of motor automobile of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, the induction mileometer of a kind of motor automobile, on the main driving wheel of vehicle ', (be contained on the semiaxis), device has a permanent magnet 1, periphery at permanent magnet 1, one sensor 2 is set, sensor 2 is a Hall element, and sensor 2 is connected to indication mechanism in the car by circuit, has a computing chip 3 in the indication mechanism, sensor 2 at first connects computing chip 3, computing chip 3 connects indicator gauge 4 by circuit again, and indicator gauge 4 can be mileometer, and indicator gauge 4 can also be velometer, the display mode of indicator gauge 4 can be pointer indicator gauge, and indicator gauge 4 can also be the digital display table.
During work, permanent magnet 1 rotates with wheel, sensor 2 is accepted induction simultaneously, and the signal that wheel is rotated becomes electric signal, send computing chip 3 to, the electric signal that computing chip 3 transmits according to some inherent datas of wheel and sensor is through conversion, be converted to mileage signal or rate signal, send display device 4 to.
The utility model can be responded to actual running speed, and changes accordingly, by circuit signal is passed to display device, the related data of vehicle ' that made the direct perception of people.Need not to obtain related data through gear drive, data is accurate, and the mileometer mean time between failures reduces greatly, and induction testing the speed do not influence wheel, effectively avoids the mechanical type mileometer, wheel is produced the problem of resistance.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the instructions just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
