Abstract

An apparatus for evaluating a watertight state of a vehicle and a method for controlling the apparatus may include an automatic ejection device having a plurality of nozzles to automatically eject water to the glass on the inside of the vehicle, an additional ejection device configured to additionally eject water separately from the automatic ejection device, a plurality of cameras configured to photograph flows of the water when water is ejected by the automatic ejection device and the additional ejection device, so that evaluation of a watertight state between the vehicle body and the glass may be preliminarily verified by allowing the water to a lower end portion of the glass through the automatic ejection device and the additional ejection device, photographing the flows of the ejected water through the cameras, and detecting whether water is introduced into the internal of the vehicle.

First claim

What is claimed is:

1. An apparatus for evaluating a watertight state of a vehicle, the apparatus comprising:
an automatic ejection device having a plurality of nozzles to automatically eject water to a glass on an inside of the vehicle;
an additional ejection device configured to eject water separately from the automatic ejection device;
a plurality of cameras configured to capture an image of flows of water when the water is ejected by the automatic ejection device and the additional ejection device,
a control device configured to control ejection of the water while interworking with the automatic ejection device and the additional ejection device; and
a body, on which the automatic ejection device and the additional ejection device are mounted and which is provided with the control device and the plurality of cameras,
wherein the body further includes a monitor connected to the control device to display the image captured by the plurality of cameras, to start and end an operation of a water ejection apparatus through a program included in the control device, and to adjust an ejection time period, an amount of ejected water and a number of ejections,
wherein the body further includes a water tank configured to supply water to the automatic ejection device and the additional ejection device and store the water and disposed with a pump configured to supply water,
wherein a direction switching valve, flow rate control valve and a flow rate detector are included between the automatic ejection device and the pump to control supply of water, and
wherein the plurality of nozzles included in the automatic ejection device eject the water in a plurality of steps through control of a button and allow control of the ejection time period and the amount of the elected water.

2. The apparatus of claim 1 ,
wherein the control device is configured to identify introduction of the water into an internal of the vehicle through materials captured by the cameras.

3. The apparatus of claim 2 , wherein each of the plurality of nozzles is provided with an on or off valve, and wherein the nozzles are independently switched on or off.

4. The apparatus of claim 2 , wherein the automatic ejection device has a curved structure to be parallel to a front surface of an inside of the glass and is fixed to the glass.

5. The apparatus of claim 2 , wherein the additional ejection device comprises:
an instantaneous ejection device configured to eject a predetermined amount of water to the glass manually or automatically by use of a control button; and
a manual ejection device configured to eject water manually to a predetermined location of the vehicle, including the glass.

6. The apparatus of claim 2 , wherein the body is movable.

7. The apparatus of claim 2 ,
wherein the monitor is connected to the control device to identify the materials in the image captured by the cameras.

8. The apparatus of claim 2 , wherein the body further comprises:
a connector configured to move the automatic ejection device and the additional ejection device to the internal of the vehicle and fix the automatic ejection device and the additional ejection device.

9. The apparatus of claim 2 , wherein the water tank further comprises:
a filter configured to filter the water supplied to the automatic ejection device and the additional ejection device.
