Embodiment
The multi-functional contactless automobile shift sensor of the utility model; On the basis of existing contactless automobile shift sensor construction; Set up contact gear induction installation; Under the abnormal operating state that is implemented in the gearbox controller in the control circuit, according to the igniting demand startup vehicle of ignition switch 13.Can find out based on this mentality of designing; The structure aspects of the contactless automobile shift sensor of the utility model mainly comprises two parts; The existing contactless automobile flat sensor structure of the first; It two is contact gear induction installations of setting up, through the description to detail above-mentioned design philosophy is done detailed explanation below, is to be understood that; This explanation only is a kind of structure under the above-mentioned thought, all belongs to the protection domain of the utility model based on any change that following concrete structure is made of above-mentioned thought.
Embodiment one:
With automatic catch speed change automobile is example; Gear as shown in Figure 2 comprises P retaining, R retaining, N retaining, D retaining, 2 retainings, L retaining, and the P retaining keeps off with N and is set at the startup gear, is known by Fig. 1-shown in Figure 3; The existing contactless automobile shift sensor part identical with the sensor of present embodiment mainly is to be fastened with lower cover plate 2 by upper cover plate 1 to form; It through being arranged on the rotation of rotor 3 in the stator that is mated 4 that has magnetic on the lower cover plate 2, is experienced the variation of magnetic intensity in the as above rotation process by Hall chip 5 under the control of control circuit; Interface Terminal 12 through being arranged on lower cover plate 2 sides links to each other with control circuit; Realize the startup of vehicle, its concrete structure is the structure of existing product, does not do too much at this and gives unnecessary details.
The innovative point of the utility model is between upper cover plate 1 and lower cover plate 2, to be provided with and contacts the gear induction installation; It comprises the contact pilotage 6 that is fixedly installed on the rotor 3, be fixedly installed on and put corresponding contact 7 with P retaining and N gear on the upper cover plate 1; Wherein contact pilotage 6 is two; The line of the two is positioned on the radial line of rotor 3 all the time; But also be two with the contact 7 of contact pilotage 6 contact matching, and on the upper cover plate 1 of the gearshift sense of rotation of contact pilotage 6, be fixed with insulation boss 10 that the effect of insulation boss 10 is to break the connection at other gears of contact pilotage 6 and contact 7 in the process that contact pilotage 6 combines with contact 7.When rotor 3 drove contact pilotage 6 rotations, contact pilotage 6 was slidingly matched with contact 7.
Know that by shown in Figure 2 contact pilotage 6 is realized the fixed-site with rotor 3 through the limiting board that is connected with it 9, as can beappreciated from fig. 4; Limiting board 9 embeds realizes in the lower cover plate 2 and the fixed-site of lower cover plate 2 that it has the cavity volume 15 of a hollow, and contact pilotage 6 is a frame structure; It embeds in this cavity volume 15 and with the sidewall of limiting board 9 and slidably cooperates; But carry out contact matching by its top and beam structure and contact 7, be provided with elastic element 8 (like spring) in the frame structure inside of contact pilotage 6, elastic element 8 one end overheads are under the upper beam of contact pilotage 6 frame structures; The other end overhead is in lower cover plate 2, and then realization applies pretightening force to contact pilotage 6.
Know by shown in Figure 6, in use, stir the gearshift major axis through the gearshift rocking arm; Thereby drive the rotor rotation several angle, when gearbox controller 11 non-normal workings, (cross when low like cell voltage), the igniting request of ignition switch 13 can not realize the startup to the starting electrical machinery relay; At this moment, because the existence of contact gear induction installation, when rotor forwards P retaining or N retaining to; Contacted with contact 7 by contact pilotage 6, because the magnetic intensity of Hall chip 5 changes, Hall voltage changes; The Hall voltage signal of this variation P/N stitch through structure terminal 12 is passed to starting electrical machinery relay 14 and makes its connection, thereby connect starting electrical machinery 16.
Embodiment two
Present embodiment and embodiment one are basic identical; Difference is the linkage structure of contact pilotage and limiting board, as shown in Figure 5ly knows that limiting board 9 is a block structure; Contact pilotage 6 is inverted frame structure; A cavity volume 15 is formed on the block bottom at limiting board 9, and two vertical supporting parts of contact pilotage 6 embed in the limiting boards 9 and can realize and being slidingly matched of limiting board 9, and forms the junction plane that slidably cooperates with contact 7 at the top of two vertical supporting parts of contact pilotage 6; The base cross members structure of contact pilotage 6 is embedded in the cavity volume 15, and cavity volume 15 guarantees the space that moves up and down of this beam structure, and overhead has elastic component 8 below crossbeam.
