Abstract

PURPOSE:To certainly discover the rain leakage point of a vehicle, by testing rain leakage into the vehicle by spraying a fluid to the surface of a car body from the outside of the vehicle while applying vibration force to the vehicle. CONSTITUTION:A vehicle 10 is moved into a shower tester 14 by a strat conveyor 12 and water is sprayed to the vehicle 10 from an up-and-down and a left and right directions. On the other hand, when the vehicle 10 is moved onto the conveyor 16 in the shower tester 14, the conveyor 16 is vibrated by a vibrating apparatus 20 having an air or oil cylinder 18 to detect the rain leakage of the vibrated vehicle 10. By this method, the rain leakage place of the vehicle 10 is certainly detected.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a vehicle vibration type rain leak test method suitable for testing rain leaks in vehicles such as automobiles.

[Prior art 1 1 (When testing for mountain leakage on both sides, the conventional method has been to place the vehicle on a strut conveyor and statically pass the vehicle through a shower tester that sprays water around the vehicle by moving the strut conveyor.) According to this conventional method, since water is sprayed onto the vehicle under the same conditions as during rainy weather, it is possible to detect rain leaks in military paintings at the earliest stage. In the test method, the vehicle only passed statically through the shower tester, so even if there was a gap in the sealant inserted into the lap joint of the panel, it was necessary to detect rain leaking from that gap. In other words, if the vehicle does not vibrate, the water accumulated in the seater etc. will not fall as water droplets through the gap in the seater, so conventional methods cannot prevent rain leakage when there is a gap in the seater etc. Therefore, even if a vehicle passes a rain leak test using the conventional test method, the conventional method has the disadvantage that the leak point is discovered when driving in the rain.

[Object of the Invention] The present invention has been developed in view of the above-mentioned conventional problems, and its purpose is to provide a vehicle vibration-type rain leak test method that can reliably discover rain leak points on a vehicle. Our goal is to provide the following.

[Summary of the Invention] In order to achieve the above object, the present invention sprays fluid onto the surface of the vehicle body from the outside of the vehicle to reduce the excitation force that causes the vehicle to vibrate.
Rain leaking into the vehicle due to the fluid being sprayed on the vehicle i1
It is characterized by being designed to test.

[Embodiments of the Invention] Preferred embodiments of the present invention will now be described with reference to the drawings.

FIGS. 1 and 2 show a configuration in which an excitation force is applied to the wheels to cause the vehicle to shake Φjj.

In FIG. 1, a vehicle 10 with one of the front and rear wheels placed on a strut conveyor 12 for moving the vehicle 10 is moved to a shower tester 1 by the strut conveyor 12.
4 and test the vehicle 10 inside this shower tester 14.
Water can be sprayed from the left and right sides of the bottom. While moving inside the shower tester 14, when the vehicle IO moves to a conveyor 16- provided approximately in the center inside the shower tester 14, as shown in FIG. The conveyor 16 is vibrated by the vibration device °20. Since the conveyor 16 is fixed at one end and supported by the springs 21 at the other end, the excitation force by the cylinder 18 can be transmitted to the wheels 22,24. Therefore, the vehicle 10 is vibrated by the excitation force from the conveyor 16 and moves toward the exit. The excitation force applied to the vehicle 10 at this time is sufficient to cause water droplets to fall from the gap if there is a gap between the sheeters inserted into the dowel joints of the panels.

As described above, in this embodiment, when water is sprayed onto the surface of the vehicle body from outside the vehicle, an excitation force sufficient to cause the vehicle to vibrate is applied to the vehicle through the wheels, so that the lap joints of the panels are If there is a gap in the sealer sleeve inserted into the part, these parts d゛6$−□M″
c'#J, -f,b? := L-All“1.

3] and FIG. 4 show a configuration in which the vehicle is vibrated by vibrating the vehicle body.

As shown in Figure 3, the strut conveyor 26.2
8, when the vehicle 10 is moved onto the vibration device 30 provided approximately in the center inside the shower tester, as shown in FIG. 34, the cylinder rod 32 is moved up and down by an air or hydraulic cylinder 36, and the vehicle 10 is vibrated.

Since the jJt outlet cutting device 30 moves on the rails 38 provided along the conveyor 26.28 in synchronization with the moving speed of the conveyor 26.28, even when performing mountain leakage tests on multi-needle vehicles, the Ti testing can be done quickly.

In addition, this is true! In this embodiment, when there is a gap in the seater 11 inserted into the lap joint of the panel as in the previous embodiment, the excitation force applied to the vehicle 10 is also applied to water ejected from the gap through the gap. is strong enough to cause it to fall.

Furthermore, even when applying an excitation force to the vehicle body, as shown in FIG.
It can also be made to vibrate.

In this case, since it is only necessary to apply an excitation force to the differential carrier 40, the configuration of the excitation apparatus is simpler than that of the excitation apparatus shown in FIGS. 3 and 4.

FIG. 6 shows a configuration in which a detection means for detecting the position of the vehicle 10 is provided in the vibration device.

In FIG. 6, a dog 42 is disposed in the vibration @ 30 having an air or hydraulic cylinder 36, etc. at a position that becomes a moving path of the tire 24, and when the tire 24 rides on this dog 42, Mechanical valve 44 can be operated.

□ Then, it is detected that the vehicle 10 has moved onto the vibration device 30 by the actuation of the mechanical valve 44. If the air or hydraulic cylinder 36 is actuated by the actuation of the mechanical valve 44, the heavy vehicle 10 is automatically vibrated. I can do it. Whether or not the vehicle 10 has vibrated a predetermined number of times is detected by a mechanical valve 46 provided ahead of the dog 42 in the lf and row j directions of the vehicle. The output can automatically stop the operation of the air or hydraulic cylinder 36.

In addition, the dog 42 and mechanical valve 4 are used to detect the position of the vehicle.
4, the position of the vehicle can also be detected by providing a position detecting means using a super wave sensor in the shower tester.

5) As explained above, according to the present invention, fluid is blown onto the surface of the vehicle body from the outside and an excitation force is applied to the vehicle to cause the vehicle to vibrate. It has the similar effect of being able to discover rain leaks that could not be found just by statically moving the roof.
