Problems solved by technology

[0002] There are a variety of gear sensing devices used in the market (such as car gear switches). Some use a moving contact and multiple static contacts to switch gears, and some use coils and inductance. Sheet and static contact sheet methods, which not only affect the service life, but also have low gear switching sensitivity; for the coil and inductance method, it changes the inductance of the three flat coils, and the rhombus of the inductive eddy current actuating element At least two sides of the contour shape are bent inward to obtain the inductance curve, which can be obtained through formula calculation and analysis. This method not only requires eddy current actuating elements with characteristic shapes, but also requires troublesome calculation and analysis and poor stability.

Embodiment 1

[0010] Embodiment 1: as figure 1 As shown, a gear sensing device includes a circuit board, on which several inductors 1' are arranged, and a metal plate 2' is arranged above the inductor 1', and several metal plates 2' are provided on the metal plate 2' for the exposed inductors. The through hole 3', the metal plate 2' can move horizontally relative to the circuit board, the number of gears is set to N, N≥2, and the number of inductances is at least M, then, 2 M-2 M -1 , the number of through holes is at least 2N-M. For example, the number of gears is 5, the number of inductors is 5, and the number of through holes is 10. The control metal plate 2' moves to the left relative to the circuit board, and the 5 inductors 1' Arrange the sequence A, B, C, D, E, set the code as 0 when the inductance 1' is exposed through the hole, code 1 when the inductance 1' is blocked by the metal plate 2', and move to different gears when the metal plate 2' moves Different binary codes are obtai...

Embodiment 2

[0011] Embodiment 2: as figure 2 As shown, a gear sensing device includes a circuit board, on which several inductors 1'' are arranged, and a metal plate 2'' is arranged above the inductor 1'', and several metal plates 2'' are arranged on the metal plate 2''. There are 3'' through holes for exposed inductors, and the metal plate 2'' can be rotated relative to the circuit board. The number of gears is set to N, N≥2, and the number of inductors is at least M, then, 2 M-2 M-1 , the number of through holes is at least 2N-M. For example, the number of gears is 3, the number of inductors is 4, and the number of through holes is 16.

Abstract

The invention relates to a gear sensing device and a using method of the gear sensing device. The gear sensing device comprises a circuit board, a plurality of inductors are arranged on the circuit board, a metal plate is arranged above the inductors, a plurality of through holes are formed in the metal plate, the metal plate can move relative to the circuit board, the number of gears is set to beN, N is larger than or equal to 2, the number of the inductors is at least M, and 2<M-2><2<=2<M-1>, the number of the through holes is at least 2N-M, the metal plate is controlled to move relative tothe circuit board to enable the inductors to be exposed out of the through holes so as to obtain different binary codes, the inductors are arranged in sequence, the codes are set to be 0 when the inductors are exposed out of the through holes, the codes are set to be 1 when the inductors are shielded by the metal plate, and different binary codes are obtained when the metal plate is moved to different gears. By adopting the technical scheme, according to the gear sensing device and the using method of the gear sensing device, the structure is simple, precision is high, the redundant capacityis high, gears can still be recognized after some inductance signals lose efficacy, and stability is high.
