Specific embodiment
Below against accompanying drawing, by the description to embodiment, the specific embodiment of the present invention is made further details of
Explanation.
Present invention back of the body magnetic-type neutral position switch structure, as shown in Fig. 2 including shell 1, the one end in shell 1 is provided with magnet steel
7, Hall chip 8 is connected with magnet steel 7, one end that metallic object 9 is provided with magnet steel 7 and Hall chip 8 with shell 1 is relative, metal
Body 9 is connected on shifting shaft and rotates with shifting shaft.
Present invention back of the body magnetic-type neutral position switch structure, magnet steel 7 is U-shape structure, and opening arranged towards metallic object 9, Hall core
Piece 8 is placed in 7 opening of magnet steel.Liner 6 is provided with shell 1, magnet steel 7 is embedded in 6 end of liner.
The body of metallic object 9 is the cylindrical structural being connected on shifting shaft, and middle part is provided with and is connected to leading on shifting shaft
Hole, is provided with the metal contact 91 with 8 relative protrusion of Hall chip on body.
Hall chip 8 exports the signal of telecommunication to ECU according to changes of magnetic field, controls automobile start-stop by ECU.
In the present invention, shell 1 is provided with installation seal washer.Metallic object 9 is made using steel, copper or aluminum, with compared with
Good electromagnetic induction effect.
In the present invention, Hall chip 8 is will be tested based on Hall effect principle using the Hall element of semi-conducting material
The magnetic field intensity of amount is converted into a kind of sensor of voltage output.There is simple structure, small volume, firm, frequency response width, dynamic
State scope is big, contactless, long service life, reliability are high, easily miniaturization and integrated the advantages of.
In the present invention, preferred 7 structure of magnet steel using U-shape structure, Hall chip 8 are placed on inside the breach of magnet steel 7,
Shifting shaft drives the metal contact 91 of the skew of metallic object 9,9 front end of metallic object to offset in rotary course, realizes the poly- of magnetic field
Effect is put, and Hall chip 8 neutral gear is recognized by the size in aggregation magnetic field and in shelves state, magnetic field reaches Hall chip 8 and sets
Influence value after, the switch triggering output reciprocal signal of two-way realizes neutral gear and the switching between shelves.Neutral position and in shelves
Position magnetic line of force distribution difference is as shown in Figures 3 and 4.The untouchable neutral gear of vehicle manual gearbox shifting, shelves switch and its
Angle recognition technology, its characteristic are to gather change neutral position switch by the rotation of the magnetized formula metallic object 9 on shifting shaft
The magnetic line of force direction of middle magnet steel 7, realizes gathering and puts magnetic effect, realize penetrating by the change in the magnetic line of force direction of door shape magnet steel
The magnetic field value size of Hall chip 8, is output as the contrary digital signal of two-way, finally realizes neutral gear with the mutual switching in shelves.
The present invention relates to the use of Hall chip 8, magnet steel 7 to be integrated in one, realized using the rotation of metallic object on gear level 9 poly-
