Description

High Speed Driving Watertight Test Equipment

The present invention relates to a high-speed driving watertight test apparatus, and more particularly, to a high-speed driving watertight test apparatus capable of supplying sufficient water to a vehicle and performing an accurate watertight test when performing a watertight test during a high-speed driving of a vehicle.

In general, when designing a vehicle, the watertightness of each sealing part of the vehicle is tested during rainy weather. As a result, a pressure difference between the inside of the vehicle and the surface of the vehicle is generated during high-speed driving, so that the door of the vehicle is inflated to the outside by negative pressure. At this time, the sealing property of the weather strip coupled to the door frame is weakened, so that rainwater flows into the vehicle.

However, in the conventional watertight test of such a vehicle, a watertight test was carried out by driving a tunnel in which water is injected at 40 to 50 km / h, and the high-speed driving test was performed on a rainy day. After soaking the water sufficiently, the car was driven at a high speed to evaluate the water inflow into the interior of the car.In this case, water stuck to the surface of the car during the watertight test could evaporate or flow along the car, which can only be performed for about 2-3 minutes. have.

Therefore, the present invention has been devised in view of the problems of the prior art, and its purpose is to provide a high speed driving watertight test apparatus capable of supplying sufficient water to the vehicle and performing an accurate watertight test when the watertight test of the vehicle is performed at high speed. It is.

As described above, in the present invention, the water loaded in the water jacket stored in the trunk room can be continuously sprayed on the vehicle body while driving at high speed, thereby accurately measuring the watertightness of the vehicle during the high speed driving.

EXAMPLE

Hereinafter, preferred embodiments of the present invention as described above will be described in more detail with reference to the accompanying drawings.

1 is a schematic view showing a high speed watertight test apparatus according to the present invention, Figure 2 is a schematic side view showing a high speed watertight test apparatus according to the present invention, Figure 3 is a perspective view showing "A" shown in FIG. to be.

As shown therein, the water jacket 1 is formed in the trunk room during the watertight test, and a plurality of motors 3 are spaced at predetermined intervals so as to discharge water from the water jacket 1 on top of the water jacket 1. Is connected to the plurality of motors, and an operation switch 70 for applying power is formed, and external water is discharged by the plurality of motors 3 to an output end of each of the plurality of motors. A connecting pipe 4 is formed to guide the plurality of branch pipes 5 which are respectively perforated to one side of the connecting pipe 4, and are coupled to each other and connected to opposite ends of the plurality of branch pipes 5, respectively. A plurality of injection holes 15 are formed such that the discharge hose 7 has a predetermined distance on the lower surface thereof.

In addition, the support frame 11 on which the discharge hose 7 is seated on the upper surface is formed to be able to extend and contract in the longitudinal direction, and is formed to correspond to both sides of the support frame 11 to form a roof panel 70 of the vehicle 100. A plurality of suction holes 9 for fixing the support frame 11 is formed.

Meanwhile, the support frame 11 includes a guide part 11b having a moving part 11a and a guide 11c that is capable of sliding the moving part 11a, and the guide part to fix the moving part 11a. A fastener 11d is inserted into the coupling hole 11e formed at the upper end of 1 lb.

In addition, the suction hole 9 is formed to be movable left / right along the guide groove 93 of the protrusion 93 formed outside the support frame 11 and has a fixture 91 for fixing the suction hole 9. ) Is formed on the upper end of the adsorption port (9).

The operation and effects of the present invention configured as described above will be described in detail below.

First, when the operation switch is turned on during high speed driving to drive a plurality of motors 3, the water charged in the water jacket stored in the trunk room is discharged to the connection pipe 4, and the connection pipe 4 is connected to the connection pipe 4. It is sent out to the delivery hose (7) through the through branch pipe (5) to wet the vehicle (100) through a plurality of injection holes (15) formed on the lower surface of the delivery hose (7) and thus sufficient for the vehicle during high-speed driving Water jet can be precisely measured by spraying water.

In addition, the support frame 11 seated on the roof panel 70 of the vehicle 100 can extend or reduce the length of the front / rear, the suction hole 9 coupled to the support frame 11 is left It can be slidably moved in the right direction and can be selectively applied according to the size of the vehicle to be subjected to the watertight test.

On the other hand, in addition to the watertightness test at high speeds, the watertightness test on the unpaved road, the condensation test on the side mirrors at high speeds, and the wiper performance test of the shielded glass.

As described above, the present invention has the advantage of measuring the water tightness of the vehicle during high-speed driving by continuously spraying the water charged in the water jacket housed in the trunk room while driving at high speed.
