Hereinafter, an operation process of the shift range lever unit 10 according to the present invention will be described with reference to the drawings. 11 to 15 are schematic partial plan views, partial sectional views, and partial enlarged views of a change state of an operation process of the shift range lever unit 10 of the present invention, and FIGS. 16 and 17 show a non-contact shift of the present invention. A schematic state diagram for the range switch unit 500 and a schematic diagram for signal output are shown. FIG. 11 shows a schematic partial plan view of a shift range lever unit 10 according to the invention, wherein schematic cross-sectional views taken along the line DD are shown in FIGS. 12, 14 and 15, in FIG. 12. A schematic cross-sectional state is shown for the components disposed in the steady state position when no external force by the driver is provided to the lever shaft 320. The lever shaft 320 is rotatably supported by the lever pivot 330, but the components are in a normal state by the elastic support of the lever detent part 340 disposed at the lower end of the lever part 300 due to the absence of external force. Position can be secured. Due to the steady-state position of the lever shaft 320, the slider connection portions 420; 4210, 4220 and the sliders 410; 4110, 4120 connected thereto also form a steady-state position, so that the switch sensor of the non-contact shift range switch unit 500 510 detects a predetermined normal state. In this case, the switch sensor 510 is the first switch sensor (5120; 5111, 5113-1, 5113-2) and the second switch sensor (5110; 5121-1, 5123-1, 5123-2) are opposed to the normal state, respectively. The magnetic field formed by the switch magnets 520 (5210 and 5220) occupying the position is sensed to generate a predetermined electrical signal corresponding thereto. That is, FIG. 13 shows a partial enlarged view of the portion indicated by the reference E in FIG. 12. The second switch sensors 5110 may include a second switch linear hall sensor 5111 and a second switch on / off hall sensor 5113-1 and 5123-2. As described above, the second switch on / off Hall sensors 5113-1 and 5123-2 are provided in the movable range in which the second switch magnet 5110 is moved to each end with the second switch linear Hall sensor 5111 interposed therebetween. It is placed at both ends. At this time, since the second switch magnet 5110 is disposed at the steady state position, the second switch linear hall sensor 5111 does not cause a change in output of an electrical signal such as a voltage. FIG. 17 shows the voltage signal output of the second switch linear Hall sensor of the present invention. The voltage signal output when the second switch magnet occupies the steady state position PA has a value of VA. In addition, the second switch on-off hall sensors 5113-1 and 5123-2 are not included in the magnetic field influence range by the second switch magnet 5110, and thus the second switch on-off hall sensors 5113-1 and 5123-2. The output by is kept off (see FIG. 16). When no external force is applied to the lever unit 300, the state of the second switch sensor and the second switch magnet in the steady state position PA is equally applied to the first switch sensor and the first switch magnet.
Then, when an external force is applied to the lever shaft 320 of the lever part 300 by the driver to apply the operating force to the lever shaft 320 in the front-rear direction, the center line of the lever shaft 320 is the center point O from the line OO. Rotate by the angle α to the center to form the line O-Oα. At this time, the lever shaft 320 and the first slider connecting portion 4220 rotate together, and the first slider 4120 connected to the first slider connecting portion 4220 is operated, and is accommodated and disposed in the first slider 4120. The first switch magnet 5220 is also operated to change the electrical output signal of the first switch sensor 5120. That is, the first switch linear Hall sensor 5121 of the first switch sensor 5120 is a shift range that is formed when the first switch magnet 5220 is out of the normal state, that is, by the front-rear operation represented by D or R. In the case of occupying the fluctuation positions PB and PC, the linear change of the output voltage occurs as shown in FIG. At least one of the on and off switching can be clearly sensed to the shift range operated by the driver, the detected signal may be transmitted to the controller (not shown) through the printed circuit board. Depending on whether the rotation direction is before or after, it is determined which first switch on / off Hall sensor is to be signal switched as shown in FIG.
Also, in this case, the second slider connection body groove 4213 formed at the end of the second slider connection body 4211 of the second slider connection part 4210 and the second slider connection formed at the second slider 4110 correspond to each other. Since the relative position fluctuation occurs between the portions 4111 in a direction perpendicular to the moving direction of the second slider 4110, the position change with respect to the moving direction does not occur in the second slider, so that the electrical power from the second switch sensor 5110 is reduced. No change in signal occurs.
On the other hand, when the operating force by the driver is applied in the left and right directions such as the shift range N-B, as shown in FIG. 15, the first slider 4120 maintains the steady state position PA. On the other hand, the center line of the lever shaft 320 rotates from the line O-O to the center O in the left and right directions by an angle β to form the line O-Oβ. At this time, the lever shaft 320 and the second slider connection portion 4210 rotate together, and the second slider 4110 connected to the second slider connection portion 4210 is movable, which is accommodated in the second slider 4110. As the second switch magnet 5210 is also operated, the electrical output signal of the second switch sensor 5110 is changed.
On the other hand, the shift range lever unit according to the present invention can be set a variety of shift range. That is, in the above embodiment, the lever shaft has been described as performing a cross-shaped rotational motion when viewed in a plane perpendicular to the longitudinal direction in a neutral state, but may be various orthogonal operations in the front, rear, left and right directions without being limited thereto.
Fig. 18 shows a modification of the shift range lever unit 10a of the present invention, wherein the lever unit 10a is capable of forward and backward movement after moving from the neutral state N to the left and right ends during the rotation operation of the lever shaft. Except for the same structure as the previous embodiment, the same components are given the same reference numerals. A lever knob cover display portion 3121a is disposed on one surface of the lever knob cover 3120a. The lever knob cover display portion 3121a has a manual operation feeling to the driver in addition to the neutral range (N; unmarked), D, R, and B as the shift range center point. Shift range deceleration (+,-) and the like are provided to provide a speed change and to achieve a speed change. 19 and 20 show a perspective view of a state in which a driver applies an operating force to a lever shaft of a shift range lever unit to change a predetermined shift range and shift range operations of B and D. One end and the other end of the lever shaft Correspondingly, the operation may be performed simultaneously in the order indicated by reference numerals 1 and 2, respectively. 21 to 28 are schematic state diagrams showing an operating state of a shift range operation according to an embodiment of the present invention, wherein a grid-shaped quadrangular structure represents an operation region of a lever shaft and a circular figure represents a selected shift range. The position on the lever knob cover indicator relative to. Switch linear Hall sensors 5121 and 5121 and switch on / off Hall sensors 5123-1, 5113-1, 5123-3 on the outer periphery of the rectangular shaft-shaped lever shaft operating area as in the previous embodiment. Wherein the switch linear Hall sensors 5121 and 5121 include a first switch linear Hall sensor 5121 and a second switch linear Hall sensor 5111, and the first switch on and off Hall sensors 5123-1 and 5113. -3) and the second switch on-off Hall sensors 5113-1 and 5123-3 respectively include first and second switch linear hall sensors 5121 and the second switch linear hall sensor 5111, respectively. It is arranged in the movable range of the sliders 4120 and 4110. The hatched configuration of the switch linear Hall sensors 5121,5121 and the switch on / off Hall sensors 5123-1,5113-3,5123-1,5123-3 in Figs. 21-28 are switches operated with the lever shaft. It means to be operated by a magnet. The switch on-off hall sensor is turned on or off, that is, the output signal is outputted as a LOW or HIGH signal, and the switch linear hall sensor generates a signal to LOW (L) or HIGH (H) or a signal change.
