FIG. 1 is a perspective view illustrating a vehicular transmission according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view illustrating a vehicular transmission according to an embodiment of the present invention.

As shown, the vehicular transmission 1 according to the embodiment of the present invention may include a shift lever 100, a shift sensing module 200, and a housing 300.

The shift lever 100 may be moved in one direction to select a shift stage. Although not shown in FIGS. 1 and 2, a knob, which serves as a handle, may be provided at an upper end of the shift lever 100, The driver can move the shift lever 100 by moving the knob in one direction to select a desired speed change stage.

Quot; shape and the like, for example, but are not limited thereto.

The vehicle transmission 1 according to the embodiment of the present invention will be described with reference to an example of a sports mode type transmission capable of performing automatic shifting and manual shifting in one shifting device, In the manual shift mode, the +, M, and - stages can be selected. In the automatic shift mode, the manual shift mode A case where the shift lever 100 is shifted to the manual shift mode is described with reference to FIG. Here, the shift pattern of FIG. 3 is only one example for facilitating understanding of the present invention, and may include various shift patterns capable of performing an automatic shift and a manual shift.

The shift sensing module 200 is located at one side of the shift lever 100 and can detect a shift mode or a shift stage selected by the shift of the shift lever 100.

The shift sensing module 200 is connected to a printed circuit board 210 on which a sensing sensor 211 for sensing at least one of a shift mode or a shift stage is mounted, A signal generating part 230 connected to the printed circuit board 210 to generate a signal corresponding to the speed change stage, a cover part (not shown) for covering one surface of the printed circuit board 210 And a rotating member 250 rotatably mounted on the cover 240 and rotating in one direction in accordance with the movement of the shift lever 100.

The sensing sensor 211 mounted on the printed circuit board 210 may include a first hall sensor 211a for sensing a speed change mode and a second hall sensor 211b for sensing a speed change stage in the selected speed change mode The first hall sensor 211a and the second hall sensor 211b can sense the shift mode and the gear stage by sensing the magnetic force generated by the magnet.

The printed circuit board 210 includes a sensing sensor 211 mounted on the printed circuit board 210 and one or more components electrically connected to the printed circuit board 210, that is, the restricting portion 220 and the signal generating portion 230, and input / output of signals.

The first hall sensor 211a senses a change in magnetic force generated by the first magnet 111 mounted on the magnet holder 110 formed on one side of the shift lever 100, Can detect a change in magnetic force generated by the rotation of the rotary member 250 from the second magnet 251 mounted on the rotary member 250.

That is, in the embodiment of the present invention, the vehicle speed change device 1 is a sports mode type in which the automatic shift mode and the manual shift mode can be used together. In order to switch from the automatic shift mode to the manual shift mode, In this case, the distance between the first hall sensor 211a and the first magnet 111 is changed, and the magnetic force is changed. The first Hall sensor 211a detects the change of the magnetic force So that it is possible to detect the change of the shift mode.

Further, the +, M, and - stages of the P, R, N, and D stages of the automatic shift mode and the manual shift mode are shifted in parallel with each other only at the point where the shift lever 100 moves between the D- The change of the magnetic force by the second magnet 251 mounted on the rotary member 250 is sensed when the rotary member 250 rotates in accordance with the movement of the shift lever 100. [

The restricting portion 220 may be a solenoid capable of restraining or restraining the movement of the shift lever 100 in accordance with the speed change stage and the signal generating portion 230 may be configured to separate the start key from the key box according to the speed change stage The key interlock switch may be a key interlock switch.

The restricting portion 220 may include a rod 222 that can move in one direction according to a control signal when the solenoid is formed. The rod 222 may include a fixing groove 120 formed in the shift lever 100, So that the movement of the shift lever 100 can be restricted or released. For example, when the P stage is selected, the rod 222 is inserted into the fixed groove 120 to restrict the movement of the shift lever 100. When the brake pedal is depressed, the rod 222 is moved from the fixed groove 120 So that the shift lever 100 can be unfastened so as to be able to select another shift range.

The restricting unit 220 and the signal generating unit 230 are electrically connected to the printed circuit board 210 according to an embodiment of the present invention. And various components for controlling the generation of the control signal and the movement of the shift lever 100 in accordance with the speed change mode or the speed change stage may be electrically connected to the printed circuit board 210. [

The restricting unit 220 and the signal generating unit 230 may include connection terminals 221 and 231 to be electrically connected to the printed circuit board 210 as shown in FIG. 231 are directly connected to the contact terminals 212a, 212b of the printed circuit board 210 without using a separate connection line and the cover portion 240 is mounted on the printed circuit board 210, 221, and 231, it is possible to maintain a state of being in close contact with the contact terminals 212a and 212b formed on the printed circuit board 210.

For example, the restricting portion 220 may have a connection terminal 221 as shown in FIG. 6, and the plurality of connection terminals 221 may have a convex portion 221a extending in one direction and having an end convex to one side When the cover 240 is mounted on the printed circuit board 210 in a state where the convex portion 221a faces the printed circuit board 210, The convex portion 221a of the connection terminal 221 and the printed circuit board 210 can be fixed so as to be in close contact with each other by applying pressure to the connection terminal 221 on one side.

As described above, according to the embodiment of the present invention, when the various components are electrically connected to the printed circuit board 210, the structure is complicated by the connection lines because the direct connection is made without using a separate connection line. It is possible to prevent a difficult problem from occurring in advance and to easily remove the cover unit 240 by separating the cover unit 240 even when the printed circuit board 210 or various parts are replaced.

However, the present invention is not limited to this, and may be applied to not only the restricting portion 220 but also the above-described signal generating portion (not shown) 230 and various other parts, and thus the shape of the cover part 240 can be variously changed.

The cover 240 is disposed adjacent to one side of the PCB 210 to protect various components mounted on the PCB 210. The cover 240 includes a restricting portion 220 on the PCB 210, And the signal generator 230 may be directly contacted without a connection line.

The rotary member 250 may be rotatably mounted in a mounting hole 241 formed in the cover portion 240 and the rotary member 250 may be inserted into the insertion hole 241 formed in the cover portion 240, And may include an insertion groove 252.

When the shift lever 100 is moved in one direction in a state where the insertion protrusion 130 is inserted into the insertion groove 252, the insertion protrusion 130 rotates with a certain radius, Can be rotated in one direction.

Since the second magnet 251 is attached to the vicinity of the center of rotation of the rotary member 250 as described above, the magnetic force is changed by the rotation of the second magnet 251 as the shift lever 100 moves And the second hall sensor 211b can detect the gear stage in the selected shift mode by sensing the magnetic force change by the second magnet 251. [

The housing 300 is formed to enclose the shift sensing module 200 as well as one side of the shift lever 100 and includes a first housing 310 and a second housing 310 coupled to each other from both sides of the shift lever 100, 320 and a third housing 330 coupled from the upper side of the first housing 310 and the second housing 320.

The first housing 310 has mounting spaces 311 and 312 on which the above-described shift sensing module 200, i.e., the printed circuit board 210, the restricting portion 220 and the signal generating portion 230, The printed circuit board 210, the restricting portion 220 and the signal generating portion 230 may be formed on the inner surface of the first housing 310 as shown in FIG. It is possible to mount the cover unit 240 described above.

The third housing 330 can be formed with a passage 331 through which one end of the shift lever 100 can move and has an operation feeling when the shift lever 100 is moved as shown in Figs. A groove 332 may be formed so as to generate a magnetic field.

The shape of the groove 332 may be variously changed according to the shift pattern described above. The shift lever 100 is supported by the elastic member 142, one side of which is in contact with the groove 332, The blades 141 can be mounted.

Therefore, in the embodiment of the present invention, when the shift lever 100 moves, the blit 141 moves in contact with the groove 332, so that a sense of operation can be generated for each gear position.

In the embodiment of the present invention described above, the case where the automatic transmission shift mode and the manual shift mode are detected is exemplified. However, the present invention is not limited to this, and the vehicle transmission 1 may be automatically It is possible to detect only the shift stages included in the shift mode of either the shift mode or the manual shift mode.

FIG. 11 is an exploded perspective view illustrating a transmission for a vehicle according to another embodiment of the present invention, and FIG. 11 is an example of a case of sensing only the speed change stage for the manual shift mode. That is, FIG. 11 shows an example of the case of detecting the movement from the D-stage to the M-stage and the selection of the + and - stages. In addition, the same components as those of FIG. 2 described above with reference to FIG. 11 have the same functions, so a detailed description thereof will be omitted, and the same reference numerals will be used for the same components.

As shown, in another embodiment of the present invention, the shift from the automatic shift mode to the manual shift mode, that is, the shift lever 100 is shifted from the D-stage to the M-stage to detect the speed change stage in the manual shift mode A first hall sensor 211a for detecting a change in magnetic force due to the movement of the first magnet 111 mounted on the magnet holder 110 formed on the shift lever 100 is mounted in a manner similar to that of FIG. And may be mounted on the circuit board 210.

The shift lever 100 is inserted into the insertion groove 251 of the rotary member 250 so that the rotary member 250 is rotated in the state where the insertion protrusion 130 of the shift lever 100 is inserted. Can be rotated in one direction.

12 and 13, the light blocking part 253 may be coupled to the rotating member 250 to rotate in one direction in accordance with the rotation of the rotating member 250, One end of the light receiving portion 253 passes between the light emitting portion 211d and the light receiving portion 211e of the photosensor 211c mounted on the printed circuit board 210 in the similar manner to the first Hall sensor 211a described above, So that it is possible to detect that the + or - stage has been selected in the manual shift mode.

Here, the rotary member 250 and the light intercepting portion 253 are hooked to each other in an alternative embodiment of the present invention. However, this is merely one example for facilitating understanding of the present invention. But may be connected by a fastening member such as a screw or an adhesive or the like.

In another embodiment of the present invention, it can be seen that the two photosensors 211c are mounted on the printed circuit board 210. This is because the selectable shift stages are the + stage and the - stage after the M stage is selected, The number of the photosensors 211c may be variously changed depending on the gear range selectable in the selected shift mode.

When the M stage is selected in the D stage of the automatic shift mode, the first hall sensor 211a detects a magnetic force change due to the first magnet 111, The light blocking portion 253 is positioned between the two photosensors 211c as shown in FIG. 14, and when the M stage is selected and the + stage or the - stage is selected, The light shielding portion 253 is positioned between any one of the light emitting portions 211d and the light receiving portion 211e of the two porter sensors 211c by the rotation so as to sense the selected gear range by intercepting the light.

2, it is known that the light blocking portion 253 is formed on the rotary member 250. It is assumed that the rotary member 250 is shared according to the type of the vehicle transmission 1 , Other components can be shared when only the printed circuit board 210 and the second magnet 251 are changed, and may be omitted if the light shielding portion is not used in FIG. 2 described above.

2 and 12 are separately described in the embodiments of the present invention. However, this is merely one example for facilitating understanding of the present invention, and the light blocking portions 253 and 253 shown in FIG. 12 The components that can be shared with each other can be designed to be mutually usable. Even if the type of the vehicle transmission 1 is changed, it is not necessary to form the components separately. The first hall sensor 211a, the second hall sensor 211b and the photo sensor 211c are used together as necessary to control the position of the first magnet 111, the second magnet 251, It may be designed to detect all of the gear positions.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
