In particular, the shift sensing module 200 according to the embodiment of the present invention can use a switch method using an electrical contact in sensing the speed change stage of the manual shift mode. In other words, when the shift command by the driver is not input, the gear stage is not sensed because the separation of the two electrodes is maintained, but when the shift command by the driver is input, the two electrodes are connected, Is detected.

Here, an elastic panel may be used for connecting the two electrodes. The elastic panel is a panel having a conductor at a position corresponding to the pattern electrode, and may be disposed at a certain distance from one surface of the printed circuit board on which the pattern electrode is formed.

4 is a perspective view illustrating a shift lever module and a shift sensing module 200 according to an embodiment of the present invention.

The shift lever module 100 and the shift sensing module 200 are disposed adjacent to each other in the housing 300. The shift sensing module 200 is disposed in the housing 300 in order to switch to the manual shift mode or to detect the shift stage in the manual shift mode. A pressure switch 220 may be provided on the body 210 of the shift lever module 100 and a pressure lever 130 may be provided on the body 120 of the shift lever module 100 for shifting the mode.

When the driver moves the shift lever module 100 in the direction of the shift sensing module 200, the shift mode is switched to the manual shift mode as the pressure lever 130 applies the vertical pressure to the pressure switch 220, The positive or negative end of the manual shift mode can be selected as the pressure lever 130 is horizontally moved on the surface of the depressed type pressure switch 220.

Details of the selection and detection of the speed change stage in the manual shift mode will be described later with reference to FIG. 8 to FIG.

5 is an exploded perspective view illustrating a shift sensing module 200 according to an embodiment of the present invention.

The shift sensing module 200 includes a printed circuit board 230, an elastic panel 250, and a pressure switch 220.

The printed circuit board 230 has a pattern electrode 240 corresponding to a speed-change mode or a speed-change stage. In addition, the printed circuit board 230 according to the embodiment of the present invention may include at least one pattern electrode 240 for sensing the speed change stage for the manual shift mode.

The pattern electrode 240 may have a pattern in which two or more electrodes are arranged with a predetermined pattern and two or more electrodes can be electrically connected to each other as a conductor provided on the elastic panel 250 is contacted.

6 is a view showing a pattern electrode and an elastic button according to an embodiment of the present invention.

The pattern electrode 240 may be formed of two or more electrodes, and FIG. 6 illustrates the pattern electrode 240 in which two electrodes are formed in a predetermined pattern.

As shown, each electrode may be arranged in a pattern in which at least one electrode branch extends in the direction of the counter electrode. Accordingly, as the conductive member provided on the elastic button contacts the pattern electrode 240 with a predetermined area, electrical connection between the electrodes is performed and the corresponding gear position corresponding to the pattern electrode 240 can be sensed.

5, an elastic button may be provided on a surface of the elastic panel 250 at a position corresponding to the pattern electrode 240.

The pressure switch 220 serves to apply pressure to the elastic panel 250. A plurality of conductors are formed on the elastic panel 250, and the pressure switch 200 can bring the specific conductor among the plurality of conductors into contact with the corresponding pattern electrodes 240. The shift sensing module 200 senses a shift mode or a shift stage corresponding to the pattern electrode 240 when the specific conductor under pressure is contacted to the corresponding pattern electrode 240 by the pressure switch 220. [

The elastic panel 250 has a protrusion or elastic button on the opposite surface corresponding to the portion where the conductor is provided. The pressure switch 220 applies pressure to the protrusion to contact a specific conductor to the corresponding pattern electrode 240 As a result, in the present invention, it can be understood that the pressure switch 220 applies pressure to a specific resilient button among a plurality of resilient buttons so that a corresponding shift mode or a speed change stage is inputted.

In the present invention, a plurality of pattern electrodes 240 are provided in a row, and a portion of the pressure switch 220 corresponding to the position of the pattern electrode provided at the center among the three pattern electrodes 240 may be formed to protrude have.

In this way, when the pressure switch 220 moves toward the elastic panel 250 as the center portion is protruded, pressure can be applied to the elastic button disposed at the center among the three elastic buttons arranged in a line .

A portion of the three pattern electrodes 240 opposite to the pressure switch 220 on one side of the pattern electrode 240 that corresponds to the pattern electrode provided at the center may be recessed.

The pressure switch 220 and the pressure lever 130 may not be arranged in a state where the center of the pressure switch 220 is precisely aligned with the center of the pressure lever 220 due to manufacturing or various reasons. The tip of the pressure lever 130 is guided to the central portion of the pressure switch 220 so that the pressure of the pressure lever 130 can be applied to the center of the pressure switch 220 in a preferential manner.

Hereinafter, the elastic button disposed at the center of the three elastic buttons is referred to as an M-step elastic button, and the elastic buttons disposed at the outer side are referred to as a + single elastic button and a single elastic button, respectively.

Similarly, among the three pattern electrodes, the pattern electrode disposed at the center is referred to as an M-stage pattern electrode, and the pattern electrodes disposed at the outside are referred to as a + single-stage pattern electrode and a -stage pattern electrode, respectively.

When the pattern electrode provided at the center of the three pattern electrodes, that is, the M-stage pattern electrode, is in contact with the conductor, the manual shift mode is input, and pattern electrodes provided on both sides of the three pattern electrodes, When the pattern electrode contacts the conductor, the positive or negative end of the manual shift mode is input.

In the present invention, the elastic panel 250 receives the gear positions of the manual shift mode, and the pattern electrodes 240 and the elastic buttons 250 are disposed in three areas of the printed circuit board 230 and the elastic panel 250, . 5 shows that two pattern electrodes and elastic buttons are provided in each region. Even if electrical connection is performed by only one of the pair of pattern electrodes and elastic buttons provided in each region, .

7 is a view showing that the pattern electrode and the elastic button are in contact with each other according to the embodiment of the present invention.

The printed circuit board 230 is provided with a pattern electrode 240 composed of a plurality of electrodes, and the elastic panel 250 is provided with an elastic button including a conductor.

The printed circuit board 230 and the elastic panel 250 are disposed adjacent to each other so as not to contact each other. When no pressure is applied to the elastic button, the plurality of electrodes constituting the pattern electrode 240 are electrically separated from each other The input of the shift mode or the gear position is not performed.

When the pressure is applied to the elastic button by the pressure switch 220, the elastic button moves toward the pattern electrode 240 so that the electric conductor electrically connects the plurality of electrodes constituting the pattern electrode 240, Or the input of the speed change stage is performed.

FIGS. 8 to 11 are diagrams illustrating the input of the speed change mode and the speed change stage according to the embodiment of the present invention.

Three pattern electrodes 811, 812 and 813 are arranged in a line on the printed circuit board 230 and three elastic buttons (corresponding to the position of the pattern electrodes 811, 812 and 813) 821, 822, and 823 are arranged in a line. Conductors 831, 832, and 833 are provided on one surface of each of the elastic buttons 821, 822, and 823.

8, a pressure switch 220 is disposed at a predetermined distance from the elastic buttons 821, 822, and 823, and a pressure lever 130 is disposed at a predetermined distance from the pressure switch 220 do.

On the other hand, the M-shaped elastic button 822 and the pressure switch 220 can be kept in contact with each other and the pressure switch 220 and the pressure lever 130 can be kept in contact with each other even when no pressure is applied . However, when the shift mode or the speed change stage is not inputted by the driver, only the contact between the M elastic button 822 and the pressure switch 220 and the contact between the pressure switch 220 and the pressure lever 130 are performed , The M-stage pattern electrode 812 may not be electrically connected.

9, when the driver operates the shift lever module 100 to move to the shift sensing module 200, the pressure lever 130 provided in the shift lever module 100 is operated by the pressure switch 220, And the pressure switch 220 applies pressure to the M-stage elastic button 822 to electrically connect the M-stage pattern electrode 812 with the conductor 832.

As the M-stage pattern electrode 812 is electrically connected, the shift sensing module 200 can detect that the shift mode is switched to the manual shift mode.

As shown in FIG. 10, when the driver operates the shift lever module 100 in the state where the M-stage pattern electrode 812 is electrically connected and moves toward the + single elastic button 821, the shift lever module 100 The provided pressure lever 130 applies a horizontal pressure to the pressure switch 220 and the pressure switch 220 changes its posture so as to apply pressure to the elastic button 821.

Thus, as the conductor 831 electrically connects the short-circuit pattern electrode 811 and the short-circuit pattern electrode 811 is electrically connected, the shift sensing module 200 is shifted to the positive It is possible to detect that the stage has been switched.

In this case, both of the M-stage pattern electrode 812 and the + stage pattern electrode 811 are electrically connected to each other. Which can be sensed by the shift sensing module 200 to be a shift stage change to the + stage.

As shown in FIG. 11, when the driver operates the shift lever module 100 in the state where the M-stage pattern electrode 812 is electrically connected, the shift lever module 100 is moved to the one-side elastic button 823, The provided pressure lever 130 applies a horizontal pressure to the pressure switch 220 and the pressure switch 220 changes its posture so that the pressure is applied to the single elastic button 823. [

As the conductor 833 electrically connects the short-circuit pattern electrode 813 and the short-circuit pattern electrode 813 is electrically connected, the shift-sensing module 200 is shifted from the manual shift- It is possible to detect that the stage has been switched.

On the other hand, when pressure is applied to the single elastic button 823, the pressure can also be maintained on the M-elastic button 822. In this case, both the M-stage pattern electrode 812 and the single pattern electrode 813 are electrically connected Which may be sensed by the shift sensing module 200 to be a shift stage changeover to the - stage.

The elasticity is excellent in elasticity and resilience, and is not easily worn. By implementing the input of the shift mode or the gear position by using such elasticity, the driver can feel the improved operation feeling and can reduce manufacturing and maintenance costs.

12A and 12B illustrate a pressure switch 220 inclined at the center and connected to both ends of the pressure switch 1200. According to another embodiment of the present invention, And may have a streamlined shape as shown.

As the contact surface with the pressure lever 130 has a streamlined shape, the driver can perform shifting with a smoother operation feeling in performing shifting to the + end or the - end.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art. It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
