Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a door stopper device for a vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a door stopper for a vehicle, which prevents a door from being closed when an obstacle is detected in an entrance / exit passage in a state where the door is opened, Stopper device and a control method thereof.

Generally, a technique of detecting a part of a human body between a window glass of a vehicle and a window frame through a sensor or the like, and stopping or stopping the operation of the glass when the interference is detected is commercialized.

On the other hand, when the user opens and closes the vehicle door, the user often closes the vehicle door without confirming whether or not another user's hand or the like is between the vehicle door.

At this time, there is a danger that hands may get caught between the vehicle door and the vehicle frame. Especially, in case of young children, the risk of this problem is not well recognized, .

The door latch comprises a door hinge, a door checker, a door striker, and a door latch. The door hinge for guiding rotation of the door is assembled by bolts. A door latch for controlling the locking of the door is disposed. As shown in Fig.

On the other hand, the door is designed to be closed with a relatively small force of the user, so that a tilt is applied to the door hinge, and the door is forcedly closed even if an elastic object is interposed between the door and the vehicle body.

Accordingly, when a door of a vehicle is closed by a relatively small force or automatically closed, fingers and the like may be caught, and studies are being conducted to prevent the door from being closed in a state where the door is opened.

The matters described in the background section are intended to enhance the understanding of the background of the invention and may include matters not previously known to those skilled in the art.

FIG. 3 is an internal perspective view of a stopper housing having a stopper for preventing a door from being closed according to an embodiment of the present invention. FIG. 4 is a perspective view of a stopper housing It is an internal perspective view.

3 and 4, a motor 300 is disposed at an inner lower portion of the stopper housing 105 and an output shaft 400 of the motor 300 protrudes to both sides of the motor 300 .

The wheels 230 are disposed on the output shaft 400 on both sides of the motor 300. The bearing 310 is disposed at both ends of the output shaft 400. The bearing 310 is inserted into the inner surface of the stopper housing 105 so that the output shaft 400 is rotated by the stopper housing 105 .

The bearing 310 may be rotatable together with the output shaft 400 and a weight 410 for absorbing vibration due to the rotation of the wheel 230 may be installed on one side of the outer circumferential surface of the bearing 310. [ May be formed by protruding.

3 and 4, a guide groove 305 is formed on the outer side surface of the stopper 100 in the up and down direction. On the inner side surface of the stopper housing 105, A guide 360 is formed. Therefore, the guide 360 and the guide groove 305 move the stopper 100 in the vertical direction in the stopper housing 105.

5 is a schematic block diagram of a door stopper device for a vehicle for preventing a door from being closed according to an embodiment of the present invention.

5, a vehicle door stopper device for preventing a door from being closed includes a door open detection unit 520, an obstacle detection unit 530, a control unit 500, a power unit 510, and a motor 300 do.

The door opening sensing unit 520 senses the opening and closing of a door that opens and closes a vehicle entrance and exit passage. The obstacle sensing unit 530 senses an obstacle present in the entrance and exit of the vehicle. The motor 300 is a rotational force source that provides a rotational force to lift the stopper 100.

If the controller 500 determines that the door is opened through the door open detection unit 520, the control unit 500 determines whether an obstacle exists in the access passage through the obstacle detection unit 530.

When the controller 300 determines that an obstacle is present, the controller 500 turns on the motor 300 by applying power through the power unit 510 and the motor 300 rotates the wheel 230, The stopper 100 is protruded to the outside of the side panel 110 through the link 240.

6 is a flowchart showing a method of controlling a stopper for preventing a door from closing according to an embodiment of the present invention.

Referring to FIG. 6, control starts in step S600. In step S610, the controller 500 monitors the opening and closing of the door through the door opening sensing unit 520. FIG.

In step S620, the control unit 500 determines that the door is opened through the door open detection unit 520. If it is determined that the door is not open, the control unit 500 performs step S610. If it is determined that the door is opened, step S630 is performed.

In step S630, the control unit 500 determines whether an obstacle exists in the access path through the obstacle sensing unit 530. If it is determined in step S640 that an obstacle is detected, the control unit 500 performs step S640 and determines that no obstacle is detected S650 is performed.

In step S660, the control unit 500 applies power to the motor 300 through the power unit 510 to raise the stopper 100 to stop the door 100 by the stopper 100. In step S650, the motor 300 is not operated or returned to its original position, so that the stopper 100 is inserted into the stopper housing 105. Then, the control ends in S670.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And all changes to the scope that are deemed to be valid.
