Hereinafter, a shift lever for a popup type automatic transmission according to the present invention will be described in detail with reference to the accompanying drawings.

5 to 9, the shift lever for the pop-up automatic transmission according to the present invention, the rotary shaft 12 is located inside the console (C), rotatable around the rotary shaft 12 The main lever 11 and the rotation shaft 12 of the main lever 11 so as to expose the main lever 11 to the outside of the console C when the main lever 11 is in use. It is connected to the main lever drive motor 13 to rotate, and the main lever drive motor 13 and the main lever rotation shaft 12 of the main lever 11 to rotate the rotational force of the main lever drive motor 13 to the main lever 11 The main lever drive chain 14 and the sub-lever rotation shaft 22 to be transmitted to the inside is located in the console (C), the sub-lever 21 is rotatably provided around the sub-lever rotation shaft 22 and And driving the rotary shaft 22 of the sub lever 21 to the outside of the console C when the sub lever 21 is in use. A sub-lever drive motor 23 connected to a sub-lever drive motor 23 for rotating the sub-lever 21 so that the sub-lever 21 is rotated, and a sub-lever rotation shaft 22 of the sub-lever drive motor 23 and the sub-lever 21. It includes a sub-lever drive chain 24 for transmitting the rotational force of the sub-lever 21.

When the driver determines the driving mode of the automatic transmission, the main lever 11 is provided to shift the TCU of the vehicle according to the driving conditions. The main lever 11 is installed in the console (C) to be rotatable about the main lever rotation shaft 12 formed on one side. In this case, when the main lever 11 is not in use, the main lever 11 is located inside the console C and is not exposed to the outside.

By operating the main lever 11, the vehicle is operated while shifting to the P stage, R stage, N stage, D stage, and M stage.

The main lever drive motor 13 serves to rotate the main lever 11. Therefore, when the main lever drive motor 13 is operated, the rotational force is transmitted to the main lever 11, it is possible to move the main lever 11 to a desired position.

The main lever driving motor 13 is provided to be rotatable when a rotational force is applied from the outside, and when the operating force is applied to the main lever 11, the main lever driving motor 13 may rotate. When the main lever 11 is operated, a rotation force in a direction opposite to the rotation direction of the rotating main lever 11 is generated so that the main lever 11 can exert a reaction force in the opposite direction in which the main lever 11 rotates. Can provide a sense of operation.

 In addition, the main lever driving motor 13 is provided with a sensor (not shown) for detecting the rotation angle, it is possible to output the rotation angle of the main lever 11 to the outside.

The main lever drive chain 14 is connected to the output shaft of the main lever drive motor 13 and the main lever rotation shaft 12 to transfer the rotational force of the main lever drive motor 13 to the main lever rotation shaft 12. To perform. Here, the reason for using the chain is to transmit the rotational force of the main lever drive motor 13 without slip, and may be connected by a timing belt or gear mechanism in which teeth are formed inward.

The sub lever 21 is applied to shift to the high stage (+) or the low stage (-) from the current shift stage as the driver intends when driving to the N stage through the main lever 11. Like the main lever 11, the sub lever 21 is rotatably provided around the sub lever rotation shaft 22 provided on one side. The sub lever 21 is also installed inside the console C, and is not exposed to the outside of the console C when not in use, and is exposed to the upper surface of the console C only when in use.

The sub lever drive motor 23 is connected to the sub lever rotation shaft 22 through a power transmission means to rotate the sub lever 21.

The sub-lever drive chain 24 is one of the power transmission means for transmitting the rotational force for the sub-lever drive motor 23 to rotate the sub-lever 21, it is provided in the form of a chain so that slip does not occur during driving. Similar to the main lever drive chain 14, the sub lever drive chain 24 may have a timing belt and a gear mechanism applied thereto.

The main lever 11 and the sub lever 21 are accommodated in the console C when not using the respective shift levers, and are exposed to the upper surface of the console C only when used. In particular, the main lever 11 is formed to have a larger size than the sub lever 21, so that the sub lever 21 is positioned inside the main lever 11, thereby providing two shift levers on the console C. The space to be installed is saved, thereby securing a space for placing another storage space or an operation button.

When the main lever rotation shaft 12 and the sub lever rotation shaft 22 are connected to the main lever driving motor 13 and the sub lever driving motor 23, the main lever rotation shaft 12 and the sub lever rotation shaft 22 are connected to decelerate, thereby driving the main lever driving motor 13 and the sub lever lever. The rotational force of the motor 23 is increased.

The operation of the shift lever for the pop-up type automatic transmission according to the present invention having the above configuration will be described.

In the pop-up type automatic transmission shift lever according to the present invention, the main lever 11 and the sub lever 21 are not exposed to the upper portion of the console C until the main lever 11 is started until the main lever 11 is started. When rotated and exposed to the upper surface of the console (C), and shifting the main lever 11 to the M stage, the sub-lever (21) is exposed to the upper surface of the console (C) to enable operation.

First, as shown in FIG. 10, when the main lever 11 is popped up, a gear operation must be performed in order to drive the vehicle, and thus the main lever driving motor 13 is started at the same time as starting. It operates to rotate the main lever 11 to expose the outside of the console (C) to make an upright state.

In this case, the angle at which the main lever 11 is popped up may be adjusted according to the driver's body by having an operation button that can be set separately. According to the driver's body shape, the seat of the driver's seat is moved forward or backward, so that the angle that the driver can easily manipulate can be adjusted. The driver of the larger figure pushes the driver's seat back, so that the main lever 11 can be tilted slightly rearward, and the smaller figure can tilt slightly forward.

In addition, when the driver does not want the pop-up of the main lever 11, the main lever 11 may be located inside the console (C). For example, starting is maintained when the vehicle is stopped, but gear shifting is not necessary. At this time, since the pop-up main lever 11 such as audio manipulation, navigation manipulation, etc. interferes with the driver's operation, the pop-up main lever 11 is manipulated by a separate pop-up toggle button (not shown) and the console C is displayed. It can be accommodated back into the, and if necessary, the main lever 11 can be popped up again.

The sub lever 21 causes the main lever 11 to pop up after the manual lever 11 is operated in the position of the manual mode (M stage). That is, since the sub lever 21 is accommodated in the main lever 11, the main lever 11 and the sub lever 21 cannot be used in the popped up state at the same time. Therefore, since the sub lever 21 is for operating the automatic transmission in the manual mode, the sub lever 21 pops up after the main lever 11 is operated in the manual mode as shown in FIG.

When the main lever 11 is shifted to the manual mode (stage M) by the driver as shown in FIG. 11 in the normal shift range, the sub lever drive motor 23 rotates the sub lever 21, FIG. As shown in 12, the sub lever 21 is in an upright state. At this time, the sub lever 21 may be shifted to the manual mode by moving forward or backward.

Meanwhile, the process of shifting using the main lever 11 will be described in detail as follows.

As shown in FIG. 10, the main lever 11 is rotated so that the main lever 11 is rotated in an upright state. When the main lever 11 is continuously rotated in the upright direction while the main lever 11 is upright, the main lever 11 is shifted by a predetermined angle.

At this time, when the driver operates the main lever 11, the main lever 11 rotates the main lever drive motor 13 as opposed to a mechanism in which the main lever drive motor 13 rotates the main lever 11.

When the user rotates the main lever 11 by a predetermined angle, the main lever driving motor 13 gives a reaction force in a direction opposite to the operation direction of the main lever 11, and despite the reaction force, the main lever 11 continues. By operating the shift mode, the next shift mode is applied, thereby giving the driver a sense of shift operation.

Therefore, as shown in FIG. 14, the section in which the main lever drive motor 13 rotates by the shift operation and the section in which the reaction force is generated during the operation of PRNDM from the P stage to the M stage are repeated. If the operation stops at the moment of this action, the automatic transmission operates in the mode at that time. For example, as shown in FIG. 13, when the operation is stopped in the reaction force section generated after the N stage while the main lever 11 is operated in the P stage to the M stage direction, the automatic transmission operates in the N stage.

On the other hand, as shown in Figure 15, even in the case of operating in the reverse order of the PRNDM from the M stage to the P stage, a reaction force section exists after each shift mode, and if the operation of the main lever 11 in the corresponding reaction force section is stopped, The shift mode at that time is applied.

Here, the main lever 11 is provided with a separate shift angle adjustment button (not shown), it is possible to set the angle at which the shift occurs. For example, when the shift angle is set to 10 degrees with the shift angle adjustment button, the speed is changed every time the main lever 11 rotates 10 degrees (PRNDM), and when the speed is set to 20 degrees, the main lever 11 rotates 20 degrees every time. By shifting, the shift angle can be adjusted according to the driver's physical condition or taste.
