Abstract
The utility model discloses an electronic sensor of a speed odometer, which can be used in different types of vehicles. The utility model is composed of a rotating shaft which is installed on a base and a shaft sleeve and provided with a magnetic ring in an upper cover, a circuit board which is fixed in a support member and is provided with Hall elements, a connecting nut and a signal wire, wherein, the magnetic ring is fixed on the rotating shaft through a fixed seat and a cover plate. Two Hall elements are positively and negatively ranged on a straight line and are fixed on the circuit board, and are parallel to the peripheral plane of the magnetic ring; the output signals of the two Hall elements are superposed, and the rotating shaft is connected with an interface of a gearbox through the connecting nut. The rotation signals of wheels of a vehicle can be converted into pulse signals which are synchronously output and are in direct proportion with the speed of the vehicle, and the pulse signals are output from the signal wire by the utility model. The utility model has the advantage of high interference resistance.
Description
The utility model relates to a kind of use and be used to simulate mechanical pointer or the matching used sensor of digital display type mileometer, electronic type vehicle speed mileage table sensor in various vehicle.
For the pointing accuracy that improves speedometer reaches when low speed driving moves, do not make the pointer shake of table, just require the sampling precision of sensor high more good more, and now on the automobile employed sensor have only a Hall element to rotate can only to send 12 pulses a week at most, if will increase pulse, will increase the volume of sensor.
The patent No. 90204323.4 " electronic type vehicle speed mileage indicating device " also provides a kind of sensor, adopts the structure that magnet steel is embedded rotating disk, and its magnetic field intensity is inhomogeneous, and the interference phenomenon is arranged between magnetic pole.
The purpose of this utility model is to provide a kind of electronic type vehicle speed mileage table sensor, can improve the pointing accuracy of speedometer, and highly versatile, anti-interference is good.
The utility model is achieved in that electronic type vehicle speed mileage table sensor is by being installed in base, axle sleeve, the wiring board that the loam cake internal fixation has the rotating shaft of magnet ring and Hall element is installed is fixed in the support member and the attaching nut, signal wire is formed, a, magnet ring are fixed in the rotating shaft by holder and cover plate, b, two Hall elements, forward and reverse arrangement is fixing in a straight line in the circuit board, and parallel with the peripheral plane of magnet ring; 2 pin ground connection of c, Hall element, 1 pin connects ten ends of power supply respectively, and 3 pin connect ten ends of power supply respectively by resistance, connect signal wire by diode.

The left view of Fig. 4, Fig. 3
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Magnet ring (7) tightly is enclosed within on the holder (6) for annular integral body, and is stamped cover plate (1 5) and is fixed in the rotating shaft (2) again;
Magnet ring (7) directly magnetizes and makes the both ends of the surface of the vertical magnet ring of pole line (7) at periphery, and decision is filled with 4～12 pairs of magnetic poles as required.
(10) fronts of two Hall elements are outside, and a reverse side outwards is arranged on the same straight line, and are fixed on the wiring board (11), and are parallel with the peripheral plane of magnet ring (7), are placed in the support member (12).Support member (12) one ends are embedded in base (5) groove, and an end is screwed on base (5) limit.The opening part of support member (12), the outer surface of two Hall elements (10) locates to be embedded with PVC plate protective seam (9) over against magnet ring (7).
Also tightly be with two bearings (4) in the rotating shaft (2), rotating shaft (2) is terminal to be fixed magnet ring (7) with nut, packing ring, split pin.
Axle sleeve (3) is fixed on the base (5), also is lined with rubber gasket (13) between base (5) and loam cake (8) and connects into integral body with screw, the fixing signal wire of being made by the three-core shielding line (14) on the side of sealing gasket (13).
Attaching nut's (1) one end be enclosed within on the axle sleeve (3), in addition end is connected with wheel box interface joint screw thread, and the place of the interior former slotting flexible axle of rotating shaft (2) insertion wheel box makes its wringing fit, sensor assembles.
Also can adopt Hall element (a 10) front or reverse side to be fixed on the wiring board (11), and with the peripheral plane parallel construction of magnet ring (7).
During use, when automotive wheel rotates, the magnet ring (7) that drives on it by rotating shaft (2) rotates, thereby make relative also parallel two Hall elements (10) cut the N utmost point or the S utmost point of magnet ring (7) simultaneously with it, because of two Hall elements are one just, one instead install, make the N utmost point energy output signal of a Hall element (10) to cutting magnet ring (7), the cutting S utmost point just can not output signal, make another Hall element (10) can not output signal on the contrary to the cutting N utmost point, but two Hall elements (10) stack connects, and makes signal wire (14) that signal output always be arranged.Convert the switching pulse signal that is directly proportional with the speed of a motor vehicle and export synchronously to regard to the turn signal that makes wheel like this, via line is handled the back by signal wire (14) output, is transported to the purpose that reaches counting in the speed of a motor vehicle indicator.
The utility model is compared with prior art: because of adopting one just, one instead on same straight line and with Two Hall elements that the magnet ring peripheral plane is parallel, and make it by the stacked system output signal, thus make tool There is the magnet ring of same number of pole-pairs can export pulse signal more than one times magnetic pole logarithm, reaches in the raising The purpose of journey meter accuracy has also reduced the jitter problem of gauge pointer in low-speed range. If do not increase The quantity that adds pulse signal can use a Hall element that the magnet ring number of pole-pairs is reduced, thereby can The volume that reduces magnet ring is convenient to again magnetize, and magnet ring is the overall structure of same material, and the rear magnetic field of magnetizing is strong Degree is even, and two adjacent same polarities do not have interference each other, and then working stability is reliable, and anti-interference is strong. Can only need to change magnet ring and rush magnetic pole logarithm 4～12 with regard to exportable 8～24 pulse signals as required, Highly versatile, volume is little, and installation and debugging are convenient.
