1 to 4 , the transmission device 1 for a vehicle according to an embodiment of the present invention may include a lever assembly 100 , a mode switching unit 200 , and a driving unit 300 . At least some of the components 100 , 200 , and 300 of the transmission device for a vehicle 1 may be accommodated in a housing (not shown) to be protected from external shocks or the like, or may be installed to have a fixed position in the housing.

The lever assembly 100 may include a lever 110 and a lever bracket 120 .

A knob (not shown) serving as a knob may be coupled to one end of the lever 110 , and the driver may select a desired shift stage by holding the knob and moving the lever 110 .

In the embodiment of the present invention, a case in which the shift stage selectable by the operation of the lever 110 includes P (parking), R (reverse), N (neutral), and D (driving) stages will be described as an example. However, the present invention is not limited thereto, and the shift stages selectable by manipulation of the lever 110 may be variously changed, and some of the aforementioned shift stages may be selected by a device such as a separately provided button or switch.

The lever 110 may be operated in at least one operation mode, and in the embodiment of the present invention, the lever 110 is a first rotational axis that is rotated about a first rotational axis Ax1 perpendicular to the longitudinal direction of the lever 110 . A case in which operation is performed in one of the first operation mode and the second operation mode rotated about the second rotation axis Ax2 parallel to the longitudinal direction of the lever 110 will be described as an example.

At this time, the first operation mode is a joystick mode in which the lever 110 is rotated about the first rotation axis Ax1 as the driver grabs the knob coupled to the upper end of the lever 110 and moves it in the front-rear direction, 2 operation mode may be understood as a rotary mode in which the lever 110 is rotated about the second rotation axis Ax2 as the driver rotates the knob about the longitudinal direction of the lever 110, in this case The second rotation axis Ax2 may be understood as an axis passing through the center of the lever 110 in the longitudinal direction of the lever 110 .

The lever 110 may be rotatably coupled to the lever bracket 120 , and in an embodiment of the present invention, the lever 110 is rotatably coupled to the lever bracket 120 about the first rotation axis Ax1 . It becomes possible to operate in the first operation mode, and the lever 110 is rotated around the second rotation axis Ax2 together with the lever bracket 120 to enable operation in the second operation mode.

The lever 110 may include a rod 111 formed in a direction perpendicular to the longitudinal direction of the lever 110 , and the rod 111 may be rotatably coupled to the lever bracket 120 .

When the lever 110 is operated in the first operation mode, the rod 111 may be rotated about the first rotation axis Ax1 to serve as a rotation axis of the lever 110 .

A magnet 111a generating a magnetic force may be provided at one end of the rod 111, and when the lever 110 is rotated about the first rotation axis Ax1, the rod 111 is rotated together and the magnet 111a ) is changed, the magnetic force by the magnet 111a is changed, and the magnetic force change according to the change in the position of the magnet 111a is detected by a detection sensor such as a 3D Hall sensor, and the position or rotation amount of the lever 110 It can be used to judge etc.

At this time, the detection result by the detection sensor may be transmitted to a controller (not shown) that controls the operation of the vehicle, and the controller is transmitted to the transmission so that a shift stage corresponding to the position or rotation amount of the lever 110 is selected according to the detection result. A control signal can be transmitted.

The lever bracket 120 includes a first detent groove positioned to contact the first bullet 112 provided at the other end of the lever 110 when the lever 110 is operated in the first operation mode as shown in FIG. 5 . 121) may be included.

The first detent groove 121 may be formed along the rotation path of the first bullet 112 provided at the other end of the lever 110 when the lever 110 is rotated about the first rotation axis Ax1. In addition, when the first bullet 112 provided on the lever 110 is elastically supported by an elastic body such as a spring, and the lever 110 is rotated about the first rotation axis Ax1, the first detent groove 121 ) to keep in contact with the groove surface.

The groove surface of the first detent groove 121 does not have a uniform inclination as a whole but may be formed to have different inclinations depending on the section, and thus, as shown in FIG. 6 , the driver moves the lever 110 to the first rotation axis ( When rotating around Ax1), the force required to operate the lever 110 is changed for each section of the groove surface, and thus a feeling of operation can be generated.

In addition, the first detent groove 121 is formed according to a rotation angle at which the lever 110 rotates about the first rotation axis Ax1 with respect to the initial position of the first bullet 112 by the first bullet 112 . the contact position of the stylus is changed, and as the rotation angle at which the lever 110 rotates about the first rotation axis Ax1 increases, the force applied to the first bullet 112 increases from one side to the other side. It may have a shape that approaches the rotation axis Ax1.

At this time, since the first bullet 112 is elastically supported so as to be swingable in the longitudinal direction of the lever 110 by an elastic body, the first bullet 112 moves along the groove surface of the first detent groove 121 when the lever 110 rotates. This may occur, and as the rotation angle at which the lever 110 rotates about the first rotation axis Ax1 increases, the compression rate of the elastic body increases and a relatively greater restoring force is generated, so that the driver uses the lever 110 Since it is necessary to apply a relatively larger force as the rotation angle of , the rotation angle of the lever 110 for selecting a desired shift stage can be recognized.

In the embodiment of the present invention, the groove surface of the first detent groove 121 is formed to have a shape that is closer to the first rotation axis Ax1 from the central portion toward both sides, respectively, to have an approximately “V” shape. This is because, when the lever 110 is operated in the first operation mode, it is rotated in both directions about the first rotation axis Ax1 to select a shift stage, and in this case, the initial position of the first bullet 112 . may be understood as an approximately central portion of the first detent groove 121 , that is, a portion furthest from the first rotation axis Ax1 among the groove surfaces of the first detent groove 121 as shown in FIG. 5 .

That is, when the lever 110 is rotated about the first rotation axis Ax1 by the driver and a shift stage is selected, an elastic body that elastically supports the first bullet 112 provided at the other end of the lever 110 . It can be compressed, and when the force applied by the driver is removed, the lever 110 moves to its original position, that is, the first bullet 112 becomes the first detent due to the restoring force of the elastic body supporting the first bullet 112 . It is possible to return to the approximately central portion of the groove 121 .

In an embodiment of the present invention, when the force applied by the driver is removed, the return of the first bullet 112 to the approximately central portion of the first detent groove 121 is an elastic body that elastically supports the first bullet 112 . It can be understood as returning to the part where the restoring force of

As described above, when the force applied by the driver is removed, returning the lever 110 to the initial position requires relatively more space for shift operation when the lever 110 maintains the selected shift stage position. On the other hand, when the lever 110 returns to its original position after the shift stage is selected, the space required for shift operation is relatively reduced, which is advantageous for miniaturization and weight reduction.

On the other hand, the lever bracket 120 is formed to protrude in a direction perpendicular to the longitudinal direction of the lever 110 on at least one side so that the lever 110 is rotated about the second rotation axis Ax2 in the first operation mode. It may include a blocking protrusion 122 .

The protrusion 122 may include an insertion groove 122a into which the second bullet 123 moving in a direction perpendicular to the longitudinal direction of the lever 110 is inserted, and the second bullet ( 123) may serve to generate a manipulation feeling when the lever 110 is rotated about the second rotation axis Ax2 in the second manipulation mode, and when the manipulation feeling is generated by the second bullet 123 A detailed description will be given later.

The above-described lever bracket 120 is moved by a mode switching unit 200 to be described later, so that the lever 110 is operated between a first position for operating in a first operation mode and a second position for operation in a second operation mode. In the embodiment of the present invention, the lever bracket 120 is moved in the vertical direction to rise when the lever 110 is operated in the first operation mode, and is lowered when operated in the second operation mode. to explain.

When the lever bracket 120 is raised by the mode conversion unit 200, the movement direction of the lever bracket 120 is guided by the first guide unit 400 positioned around the lever bracket 120, and the lever ( The rotation of 110 about the second rotation axis Ax2 may be blocked.

In other words, since the lever 110 is rotatably coupled to the lever bracket 120 about the first rotational axis Ax1, the lever 110 is blocked from rotating about the second rotational axis Ax2. On the other hand, the lever bracket 120 is in a rotatable state about the second rotation axis Ax2.

In this case, the first guide part 400 may include a blocking groove 410 formed to extend along the movement direction of the protrusion 122 when the lever bracket 120 is raised, and the protrusion 122 is the first When it is inserted into the blocking groove 410 of the guide part 400, the lever bracket 120 is blocked from rotating about the second rotation axis Ax2, so that the lever 110 is rotated about the second rotation axis Ax2. rotation can be blocked.

Meanwhile, in the embodiment of the present invention, a case in which an insertion groove 411 extending in the movement direction of the protrusion 122 is formed on the bottom surface of the blocking groove 410 will be described as an example, but this is It may be understood to be for movement of the inserted second bullet 123 , and the insertion groove 411 may be omitted.

As described above, when the lever assembly 100 is raised, the lever 110 is rotatably coupled to the lever bracket 120 about the first rotation axis Ax1 , and the lever bracket 120 has the protrusion 122 . ) is inserted into the blocking groove 410 of the first guide part 400 to block rotation about the second rotation axis Ax2, so that the lever 110 rotates the first rotation axis Ax1. 1 Operation mode becomes available for operation.

The above-described lever assembly 100 may be lowered by the mode switching unit 200 when the lever 110 is required to be switched from the first operation mode to the second operation mode.

The mode conversion unit 200 includes a shaft 210 rotating about a central axis C perpendicular to the longitudinal direction of the lever 110 and a shaft 210 in a direction perpendicular to the central axis C of the shaft 210 . ) to be spaced apart from each other by a predetermined interval and may include a connection part 220 connected to the lever bracket 120 .

In the embodiment of the present invention, the central axis (C) refers to the center of rotation of the shaft 210, and, like the above-described first axis of rotation (Ax1) and second axis of rotation (Ax2), it is an axis on which rotation is the center. can be understood

The shaft 210 may rotate about the central axis C by a driving force generated from the driving unit 300 , and the connecting unit 220 may be connected to each other through the lever assembly 100 and the link member 230 . .

In the embodiment of the present invention, the connection part 220 is formed by bending at least a portion of the shaft 210 to be spaced apart from the shaft 210 at a predetermined distance in a direction perpendicular to the central axis C of the shaft 210. For example, although not limited thereto, the connection part 220 may be formed separately from the shaft 210 and coupled to each other.

The link member 230 is accommodated in the receiving groove 124 of the lever bracket 120 at one end and the pivot head 231 pivotally coupled to the lever bracket 120 and the connecting part 220 at the other end are penetrating so as to be positioned therethrough. A hole 232 may be formed.

At this time, the length of the link member 230 is fixed, and since the position of the connection part 220 is changed based on the central axis C of the shaft 210 according to the rotation angle of the shaft 210 , the shaft 210 . When the position of the other end of the link member 230 is changed according to the rotation angle of there will be

For example, when the connection part 220 is located on the upper side with respect to the central axis C of the shaft 210 , the lever assembly 100 is raised due to the force applied by one end of the link member 230 and the lever When the 110 is moved to the first position to be operated in the first operation mode, and the connection part 220 is located below the central axis C of the shaft 210, the lever assembly 100 is lowered. The lever 110 can be moved to the second position for being operated in the second operation mode.

When the lever assembly 100 is lowered by the mode switching unit 200 as described above, the protrusion 122 of the lever bracket 120 is separated from the first guide unit 400 as shown in FIGS. 7 and 8 . At the same time, when the lever 110 of the second bullet 123 is rotated about the second rotation axis Ax2, the second detent groove 500 formed along the rotation path of the second bullet 123 as shown in FIG. 9 . ) so that the lever bracket 120 is rotatable about the second rotation axis Ax2.

In the embodiment of the present invention, when the lever assembly 100 is raised, the lever 110 is operated in the first operation mode, and when the lever assembly 100 is lowered, the lever 110 is operated in the second operation mode. is described as an example, it may be understood that the first guide part 400 is located above the second detent groove 500 , and the present invention is not limited thereto and the lever 110 according to the elevation of the lever assembly 100 . ), the positions of the first guide part 400 and the second detent groove 500 may vary depending on the operation mode.

When the lever assembly 100 is lowered by the mode switching unit 200 , the lever 110 is blocked from being rotated about the first rotation axis Ax1 by the second guide unit 600 , and the second It may be rotatable about the rotation axis Ax2 and may be operated in the second operation mode.

The second guide part 600 may include a guide hole 610 formed to have a curvature of a circle having a predetermined radius about the second rotation axis Ax2, and the lever 110 is the lever 110. It may include a guide pin 125 formed in the longitudinal direction of the.

In the embodiment of the present invention, a case in which the guide pin 125 is formed to extend in the longitudinal direction of the lever 110 from the rod 111 will be described as an example, but the present invention is not limited thereto. It may be formed in various structures that are linked to the rotation of 110 .

The guide pin 125 is positioned in the longitudinal direction of the lever 110 to be inserted into the guide hole 610 when the lever assembly 100 is lowered, and the guide hole 610 is a second rotation axis as shown in FIG. 10 . On the other hand, when the lever 110 is rotated about the first rotational axis Ax1, the guide pin 125 is in a straight direction Since the lever 110 is rotated around the first axis of rotation (Ax1), the rotation of the lever 110 is blocked, and when the lever 110 is rotated about the second axis of rotation (Ax2), the guide pin 125 is a guide It moves along the hole 610 so that the lever 110 may be operated in the second operation mode.

The lever bracket 120 may be provided with a magnet 126 whose position is changed according to the rotation of the lever 110, and when the lever assembly 100 is lowered and the lever 110 is operated in the second operation mode, The magnetic force change according to the position of the magnet 126 may be detected by a sensing sensor such as a 3D Hall sensor and used to determine the position or rotation amount of the lever 110 .

When the lever 110 is rotated about the second rotation axis Ax2 in the second operation mode, the second bullet 123 is maintained in contact with the second detent groove 500 by the elastic body. .

The groove surface of the second detent groove 500 may not have a uniform inclination as a whole as shown in FIG. 11 but may be formed to have different inclinations depending on the section, whereby the driver moves the lever 110 to the second rotation axis ( When rotating around Ax2), the force required to operate the lever 110 is changed for each section of the groove surface, and thus a feeling of operation can be generated.

In addition, the second bullet 123 comes into contact with different positions on the groove surface of the second detent groove 500 according to the rotation angle at which the lever 110 rotates about the second rotation axis Ax2, As the rotation angle at which the lever 110 rotates about the second rotation axis Ax2 increases, the force applied to the second bullet 123a increases from one side to the other side so that the second rotation axis Ax2 gets closer. may have a shape.

At this time, since the second bullet 123 is elastically supported by an elastic body such as a spring, a manipulation feeling may be generated when the lever 110 rotates, and the lever 110 rotates about the second rotation axis Ax2. As the rotation angle increases, the compression ratio of the elastic body increases and a relatively large restoring force is generated. Therefore, as the rotation angle of the lever 110 increases, the driver needs to apply a greater force. It is possible to recognize the rotation angle of the lever 110 for

In the embodiment of the present invention, the groove surface of the second detent groove 500 is formed to have a shape that is closer to the second rotation axis Ax2 from the central portion toward both sides, respectively, to have a substantially “V” shape. This is because, when the lever 110 is operated in the second operation mode, it is rotated in both directions about the second rotation axis Ax2 to select a shift stage, and in this case, the initial position of the second bullet 123 may be understood as a central portion of the second detent groove 500 , that is, a portion furthest from the second rotation axis Ax2 among the groove surfaces of the second detent groove 500 .

That is, when the lever 110 is rotated about the second rotation axis Ax2 by the driver and the shift stage is selected, the elastic body that elastically supports the second bullet 123 provided in the lever bracket 120 is compressed. When the force applied by the driver is removed, the lever 110 moves to its original position due to the restoring force of the elastic body supporting the second bullet 123, that is, the second bullet 123 moves to the second detent groove. It is possible to return to approximately the central portion of (500).

In an embodiment of the present invention, when the force applied by the driver is removed, the second bullet 123 returns to the approximately central portion of the second detent groove 500 is an elastic body that elastically supports the second bullet 123 . It can be understood as returning to the part where the restoring force of

The driving unit 300 may include an actuator 310 and a transmission gear 320 .

The actuator 310 may generate a driving force when it is required to change the operation mode of the lever 110 , and the driving force generated from the actuator 310 is transmitted to one end of the shaft 210 through the transmission gear 320 . It is transmitted to the driving gear 211 provided to rotate around the central axis C of the 210 so that the shaft 210 can be rotated.

In an embodiment of the present invention, the driving unit 300 may be installed to be fixed to the housing, which is a magnet due to electromagnetic waves generated when the actuator 310 is driven when the position of the driving unit 300, particularly, the actuator 310 is changed. This is to prevent malfunctions caused by electromagnetic waves in advance, such as the magnetic force change is not normally detected due to the change in the position of the

On the other hand, in order for the lever 110 to be operated in any one of the first operation mode and the second operation mode, it is necessary to switch the operation mode, and for this purpose, it is coupled to one end of the lever 110 as shown in FIGS. A mode switching button 710 may be provided on the cover 700 positioned between the knob 113 and the lever bracket 120 .
