Description

Door Closing Control Device for Vehicles {EQUIPMENT FOR CONTROLLING CAR DOOR CLOSING}

The present invention relates to a device for preventing the closing of the vehicle door according to the presence of people or foreign objects at the passenger entrance.

Recently, a door having a structure for automatically opening and closing a passenger entrance by sliding a van has been proposed.

The automatic opening and closing door is a structure that is opened and closed by moving the rail along the rail formed on the upper and lower rim of the passenger entrance by the driving motor and the driving roller when the occupant presses the operation button.

However, the existing automatic opening and closing door is open or closed, but the passenger must press the operation button unconditionally, if the door is closed by pressing the operation button in the process of passengers getting on and off, the person who gets on and off gets stuck between the door and the passenger entrance. Accidents occur frequently.

Such safety accidents are frequently generated not only on automatic opening and closing doors, but also on passenger car doors, for example, when a person outside the vehicle closes the door without knowing who is getting off, and the door is strongly hit by the head of the person who is getting off. It happens a lot.

In addition, if the door is closed in a state other than the person is located at the passenger entrance there is a problem that can be damaged as well as the door.

Hereinafter, with reference to the configuration illustrated in the drawings to explain an application example of the specific configuration of the present invention.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.

The door closing control device for a vehicle according to the present invention includes a movement control unit 200, an open / close detection unit 300, an object detection unit 400, and a main control unit 500 as shown in FIGS. 1 and 2. It is configured by.

In this embodiment, the vehicle door 100 is slid left and right on the passenger exit 110 through the movement control unit 200 is automatically opened and closed, the movement control unit 200 is installed on the upper and lower edges of the vehicle door 100. It includes a driving wheel 210 and a driving motor 220 connected to the driving wheel 210.

At this time, the driving wheel 210 is in contact with the rim of the passenger entrance 110 to allow a smooth sliding in the opening and closing process of the vehicle door 100, the drive motor 220 is also installed in the vehicle door 100 driving wheel Directly driving 210 serves to allow the vehicle door 100 to slide by the driving force of the driving wheel 220.

The drive motor 220 is connected to the operation button (1) in the vehicle through the main control unit 500 to be described later operates in the form of driving and stopping as the passenger operates the operation button (1).

In addition, the opening / closing detection unit 300 serves to detect whether the vehicle door 100 that is opened and closed through the movement control unit 200 is formed as a general position sensor structure and the vehicle door of the passenger entrance 110. In the process of opening (100) is located on the sliding path of the vehicle door (100) or is installed on the point that is finally located after fully opened.

The opening / closing detection unit 300 may be implemented in the form of a limit switch or an optical sensor. First, when applied in the form of a limit switch, the vehicle door 100 of the vehicle body C is completely opened. Is installed in, the vehicle door 100 is completely opened and at the same time the contact is made in a manner to recognize the open state of the vehicle door 100.

When applied in the form of an optical sensor, the light emitting unit and the light receiving unit are installed to face the moving section of the vehicle door 100 or the point where the vehicle door 100 is completely opened to detect the vehicle door 100 passing between the light emitting unit and the light receiving unit. To recognize the door open state.

The object detecting unit 400 is connected to the opening and closing detection unit 300.

The object detecting unit 400 serves to detect the presence or absence of a person or other object on and off the passenger door 110 while the vehicle door 100 is open, and a general infrared sensor structure is applied.

The object detecting unit 400 is installed around the edge of the passenger entrance 110 of the vehicle body C so that infrared rays cross the passenger entrance 110 toward the opposite edge.

In this case, the infrared sensing method of the object detecting unit 400 is a direct reflection type, that is, a separate light receiving structure is not provided, and the infrared light emitted from the light emitting unit is directly inverted from the detector.

Of course, in addition to the direct bottom reflection type, the object detecting unit may be variously modified, such as a general transmissive structure consisting of a light emitting part and a light receiving part, or a flat mirror type having a light receiving part having a mirror type reflector structure.

At this time, the object detection unit 400 is installed so as to be inclined at a predetermined angle in the state positioned at the upper edge of the passenger entrance 110 as shown in the drawing, so that the infrared ray traverses the passenger entrance 110 in the diagonal direction.

In this way, as shown in FIG. 2, infrared rays traverse in the diagonal direction, so that the sensing section can be secured over the entire area of the passenger entrance 110 as compared with the case where the infrared rays are installed to be transmitted in a straight direction as shown in FIG.

In other words, the infrared transmission area is not actually increased, but because the diagonal transmission reduces the space where passengers can get on and off during passenger entrance, the detectable area is increased accordingly.

Of course, the installation position of the object detection unit 400 may be installed on the lower edge or the middle of the rim in addition to the upper edge of the passenger entrance 110, and can secure a wider sensing area than the linear transmission structure through the transmission in the diagonal direction. If it is a branch, it can be installed in various ways.

The object detecting unit 400 is connected to the opening and closing detecting unit 300 through the main control unit 500 to detect the object simultaneously with the opening of the vehicle door 100.

In addition, the object detecting unit 400 is connected to the driving motor 220 of the movement control unit 200 through the main control unit 500 so that a person or an object may be placed on the passenger entrance 110 while the vehicle door 100 is opened. The detection signal is transmitted to the driving motor 220 through the main controller 500.

Hereinafter will be described the operation of the present embodiment by the above configuration and the unique effects generated in the process.

First, as shown in FIG. 2, as the passenger in the vehicle operates the operation button 1 in the state in which the vehicle C is stopped, the vehicle door 100 is completely opened and at the same time being in direct or indirect contact with the object detecting unit 400. The object detecting unit 400 is operated.

As a result, the infrared ray is transmitted from the object detection unit 400, and as described above, the infrared ray is transmitted to cross the passenger entrance 110 in an oblique direction as described above, even though only one object detection unit 400 is installed. The sensing area can be secured over the area.

In this state, the personnel are getting on and off through the passenger entrance 110, and in this process, the getting on and off personnel passes through the infrared rays of the object detecting unit 400, the object detecting unit 400 continuously receives the detection signal from the main control unit ( 500).

As such, the main controller 500 receiving the object presence signal on the passenger entrance 110 continuously sends an operation stop signal to the drive motor 220 of the movement control unit 200, thereby closing the vehicle door in the process of getting on and off. This becomes impossible.

That is, even if the driver or the like in the exaggeration to operate the drive motor 220 by pressing the operation button (1) incorrectly, because the vehicle door 100 is not operated, the vehicle door is closed in the process of getting on and off, so The safety accident that is caught between the passenger exit 110 is to be prevented.

As such, the present invention basically includes a separate object detecting unit 400 on the passenger entrance 110 to force the closing operation of the vehicle door 100 in accordance with the presence or absence of the unloading personnel in the state in which the vehicle door 100 is opened. The basic feature is to prevent a safety accident due to a malfunction by blocking.

In particular, as infrared rays transmitted from the object detecting unit 400 cross the passenger entrance 110 in a diagonal direction, only one object detecting unit 400 can secure a detection section over the entire passenger entrance 110. The key feature is that the installation structure can be simplified.

For reference, in addition to the direct connection structure between the vehicle door and the open / close detection unit, the open state detection of the vehicle door may be implemented as a connection structure between the drive motor and the open / close detection unit of the moving control unit.

That is, the process of operating the driving motor to open the vehicle door or the moment when the driving motor is stopped because the vehicle door is completely opened, it can be implemented in a manner that the opening and closing detection unit detects the stop signal.
