Abstract
The utility model relates to an automobile direction sensor used for judging the advancing or retreating directions of a vehicle and testing the driving distance of an automobile. In a threaded metal shell, two Hall integrated circuits, a trigger, a dispersion gate, a load resistor and a filter capacitor are connected on a circuit board, and are then connected with a socket connector. When rotating at the end face of the sensor, a magnet successively sweeps over the surfaces of the two Hall integrated circuits, so that a time difference is incurred; in addition, the two Hall integrated circuits generate output signals with a phase difference, and the output signals realize the identification of the directions after being processed by a digital circuit. The automobile direction sensor realizes the characteristics that only one sensor is needed, the volume is small, the needed space is small and the installation is convenient; moreover, by adopting the method of calculating pulse, the moving distance or speed of the vehicle can be obtained.
Description
Technical field
The utility model relates to a kind of automobile steering sensor, is used to direction discriminating and the testing automobile operating range of judging that vehicle advances or falls back.
Background technology
At present, the vehicle reverse direction of advancing is differentiated, needs mix a series of interlock circuits again with certain relatively angle (angular dimension depends on that measurand is by the holding position) placement of two identical sensors of performance, could realize function.This mode not only needs with two sensors and special-purpose treatment circuit, and installation volume, all specific to some extent requirement in position.Give and to use and installation is made troubles.
The utility model content
1, technical matters to be solved:
At above deficiency, the utility model provides a kind of volume automobile steering sensor little, easy for installation.
2, technical scheme:
The utility model is by linking to each other with wiring board unit 1 at connector 4 one ends, the other end links to each other with output lead, wiring board unit 1 is positioned at shell 2, and epoxy resin 5 is filled between shell 2 and the wiring board unit 1, and shell 2 outsides are provided with two nuts 3 and are spun on the shell.The circuit of described wiring board unit 1 is connected to: Hall integrated circuit IC1 links to each other with filter capacitor C1, and pull-up resistor R1 is connected between Hall integrated circuit IC1 and the filter capacitor C1; Hall integrated circuit IC2 two ends are connected with filter capacitor C5, filter capacitor C2 respectively, and pull-up resistor R2 is connected between Hall integrated circuit IC2 and the capacitor C 2; Hall integrated circuit IC2 and Hall integrated circuit IC1 are parallel to the Sheffer stroke gate IC4 that trigger IC3 input end is connected to the back, by filter capacitor C3, C4 filtering output.Pull-up resistor R1, R2 can select that 5.1k---10K realizes.
3, beneficial effect:
The utility model has realized that sensor only needs one, and volume is little, and required space is little, the characteristics of being convenient to install, and can obtain distance or the speed that vehicle moves by the mode of calculating pulse.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 longitudinal profile of the present utility model structural map.
Embodiment
In being threaded metal shell, two Hall integrated circuits, trigger, Sheffer stroke gate, pull-up resistor, filter capacitors connect in the circuit board, link to each other with connector again.When magnet rotates at the sensor end face, magnet successively streaks the surface of two Hall integrated circuits, and life period is poor, makes two Hall integrated circuits produce and has the output signal of phase differential, through the processing of digital circuit, realizes the discriminating of direction.
In Fig. 1, Hall integrated circuit IC1 links to each other with filter capacitor C1, and pull-up resistor R1 is connected between Hall integrated circuit IC1 and the filter capacitor C1; Hall integrated circuit IC2 two ends are connected with filter capacitor C5, filter capacitor C2 respectively, and pull-up resistor R2 is connected between Hall integrated circuit IC2 and the capacitor C 2; Hall integrated circuit IC2 and Hall integrated circuit IC1 are parallel to the Sheffer stroke gate IC4 that trigger IC3 input end is connected to the back, by filter capacitor C3, C4 filtering output.General pull-up resistor can select 5.1k---10K, and filter capacitor C1, C2, C3, C4 decide according to the speed of car operation.
Among Fig. 2, connector 4 one ends and wiring board unit 1 (comprise Hall integrated circuit, trigger, Sheffer stroke gate, resistance, electric capacity, wiring board is formed) link to each other, the other end links to each other with output lead, and wiring board unit 1 is positioned at shell 2, epoxy resin 5 is filled between shell 2 and the wiring board unit 1, and shell 2 outsides are provided with two nuts 3 and are spun on the shell.
Though the utility model with preferred embodiment openly as above; but they are not to be used for limiting the utility model; anyly have the knack of this skill person; in the spirit and scope that do not break away from the utility model; can do various variations or retouching from working as, what therefore protection domain of the present utility model should be defined with the application's claim protection domain is as the criterion.
