Description

DOOR SYSTEM FOR VEHICLE

An embodiment of the present invention relates to a door system for a vehicle, and more particularly, to a door system for a vehicle in which a door handle is omitted.

Typically, a vehicle is configured with one or more doors for passengers to enter and exit the vehicle. Each door is configured with an outside door handle for opening and closing the door from the outside, and an inside door handle for opening and closing the door from the inside.

Among these, the outside door handle is usually configured to protrude outward from the outer panel of the door so that the passenger can easily grasp it. However, the outside door handle has the disadvantage of lowering the appearance of the vehicle, causing noise while driving, and reducing driving performance due to frictional resistance with the air.

To solve these shortcomings, auto flush door handles (also called pop-out door handles) have recently been applied to vehicles. Auto flush door handles are stored inside the outer panel when the vehicle is parked or driven, and have an operating structure in which the door handle pops up to the outside of the outer panel when the door is opened or closed in conjunction with a smart key.

However, conventional auto flush door handles have the disadvantage of adding a complex configuration for storing/popping up the door handle to the door opening/closing structure of the existing outside door handle, which increases the complexity of the components installed in the limited space between the door panels, and thus increases cost and weight.

In addition, in severe winter, the auto flush door handle freezes due to ice and does not pop up, making it impossible to open the door, and the vehicle cannot be driven immediately because the ice needs time to melt, which causes customer dissatisfaction.

The information contained in this background section has been prepared to promote understanding of the background of the invention and may include matters that are not prior art already known to those skilled in the art.

Embodiments of the present invention aim to provide a vehicle door system that performs door opening/closing control and pop-up control in normal times, while allowing the door to be manually unlocked in an emergency due to a vehicle discharge or the like.

In addition, the operating lever (33) of the first electric mechanism (30) is in a state of contacting the end of the first operating rod (51) through the first arm portion (41) by the elastic force of the first spring (47).

Additionally, the second operating rod (65) of the second actuator (61) of the second electric mechanism (60) is in a state of being moved backward by the driving of the second servo motor (63).

Furthermore, the emergency lever (90) is located on the same plane as the outer panel (5) of the door (1) and blocks (closes) the key hole (83) of the door lock mechanism (80) through the blocking portion (92).

In this door lock state, when a user approaches the door (1) with the smart key (3) in his/her possession to open the door (1), the body controller receives the wireless signal (RF) of the smart key (3) and releases the sleep mode.

In addition, the control module (70) applies an electric signal to the latch lock unit (23) of the latch module (20) when the smart key (3) is recognized to unlock the latch of the door latch unit (21).

And, the control module (70) waits for a switch input signal input by the user's operation, and the switch signal is input through a switch member (10) of a button type or touch type while waiting.

Accordingly, the control module (70) applies an electrical signal to the first actuator (35) of the first electric mechanism (30) by inputting a switch signal by the switch member (10).

Then, as shown in Fig. 6, the first actuator (35) moves the first operating rod (51) forward by driving the first servo motor (49) according to an electrical signal.

Here, the first operating rod (51) pushes the first arm (41) of the operating lever (33) to rotate the operating lever (33) in one direction, and the operating lever (33) rotates in one direction while overcoming the elastic force of the first spring (47).

In this way, as the operating lever (33) is rotated in one direction, the door lock of the door latch part (21) is released through the connecting rod (37).

Then, when the control module (70) applies an electric signal to the first actuator (35), the first actuator (35) moves the first operating rod (51) backward by driving the first servo motor (49) according to the electric signal. At this time, the operating lever (33) is rotated in the other direction by the elastic restoring force of the first spring (47) while the door latch portion (21) is unlocked, and returns to the original position.

Next, the control module (70) applies an electrical signal to the second actuator (61) of the second electric mechanism (60). Then, the second actuator (61) moves the second operating load (65) forward by driving the second servo motor (63) according to the electrical signal, as shown in Fig. 7.

Accordingly, the second operating rod (65) pops up the door (1) along the width direction with a force that pushes the striker (7) to an opening amount of the set reference value. Accordingly, as shown in Fig. 11, the user can open the door (1) by holding the edge of the popped-up door (1) with his hand.

In this process, if the opening amount of the door (1) exceeds the set reference value, the control module (70) applies an electric signal to the second actuator (61) to drive the second servo motor (63) to move the second operating rod (65) backward.

Meanwhile, when the door (1) is closed, a discharge of the vehicle, a failure of the body controller and/or the control module (70), etc. may occur. In such a case, an emergency situation may occur, such as the body controller and/or the control module (70) not recognizing the smart key (3) and the switch signal not being input through the switch member (10).

In the case of such an emergency situation, as shown in FIGS. 8 and 9, when the user presses the pivot joint (91) of the emergency lever (90) by hand, the emergency lever (90) rotates by a set rotation angle in the outward direction (e.g., in the direction of the width of the vehicle) of the door (1) with the pivot joint (91) as the center. At this time, the emergency lever (90) overcomes the elastic force of the second spring (99) and rotates in the outward direction of the door (1). Accordingly, the blocking part (92) of the emergency lever (90) opens the key hole (83) of the door lock mechanism (80).

Then, when the key (81) is inserted into the key hole (83) and the key cylinder (87) is rotated through the key (81), the key rod (89) rotates, and accordingly, the latch lock of the latch lock part (23) is manually released.

As described above, when the latch lock of the latch lock part (23) is manually released and the key (81) is removed from the key hole (83), the emergency lever (90) is rotated inwardly of the door (1) around the pivot joint part (91) by the elastic restoring force of the second spring (99) and returns to its original position.

Next, as described above, by pressing the pivot joint (91) of the emergency lever (90), the emergency lever (90) is rotated by a rotation angle set toward the outside of the door (1), and the emergency lever (90) is rotated by a rotation angle greater than the rotation angle set toward the outside of the door (1) by the user's grip. At this time, the emergency lever (90) overcomes the elastic force of the second spring (99) and rotates toward the outside of the door (1).

Then, the rib portion (93) of the emergency lever (90) pushes the first arm portion (41) of the operating lever (33) to rotate the operating lever (33) in one direction. At this time, the operating lever (33) overcomes the elastic force of the first spring (47) and rotates in one direction.

In this way, the operating lever (33) is rotated in one direction to release the door lock of the door latch portion (21) through the connecting rod (37). Here, the operating lever (33) is rotated in the other direction by the elastic restoring force of the first spring (47) while the door lock of the door latch portion (21) is released, and returns to the original position.

In this state, when the user releases the emergency lever (90) that was being held, the emergency lever (90) rotates inwardly toward the door (1) around the pivot joint (91) by the elastic restoring force of the second spring (99) and returns to its original position.

Therefore, the user can open the door (1) with the door latch part (21) unlocked and get into the vehicle.

According to the vehicle door system (100) according to the embodiment of the present invention as described so far, in normal times, the door lock of the latch module (20) can be electrically unlocked according to a switch signal, and the door (1) can be popped up.

Accordingly, the vehicle door system (100) according to the embodiment of the present invention can completely omit the door handle through the pop-up and open/close control of the door (1), thereby solving the noise and driving performance problems caused by the existing door handle and the problem caused by freezing of the existing auto flush door handle.

In addition, the vehicle door system (100) according to the embodiment of the present invention can omit complex components for operating a door handle in a limited space inside the door (1), secure a future-oriented design element through a smooth body line, and simplify the molding and painting process of the outer panel (5).

Furthermore, the vehicle door system (100) according to an embodiment of the present invention can manually release the latch lock of the latch module (20) through the door lock mechanism (80) in an emergency due to a discharge of the vehicle, a failure of the body controller and/or the control module (70), etc. In addition, the vehicle door system (100) according to an embodiment of the present invention can manually release the door lock of the latch module (20) through the emergency lever (90) in an emergency.

Therefore, the vehicle door system (100) according to the embodiment of the present invention can further improve the marketability of the vehicle and enhance convenience in an emergency.

Although preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and includes all changes that can be easily modified and deemed equivalent by a person having ordinary skill in the art to which the present invention pertains from the embodiments of the present invention.
