Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a waterproof test device for testing the waterproofness of automobiles.

BACKGROUND OF THE INVENTION Various tests are conducted to test the waterproofness of automobiles during their manufacturing process. One of these tests is a shower test that simulates rainy weather. This shower test sprays water from a predetermined number of nozzles installed on the ceiling, floor, and both sides of the test room onto the car body brought into the test room to test the waterproofness of the car. It is something.

Problems that the invention aims to solve The test room where the above waterproof test is carried out tests the waterproofness of many types of cars in one test room, so the number of nozzles installed in the test room is limited to the number of nozzles installed in the test room. It is designed to accommodate the largest vehicle models. If you install enough nozzles to support the largest car model in this way, there will be no problems when testing the waterproofness of large car models, but
When conducting a waterproof test for small car models, there was a problem in that water was sprayed from nozzles that were not necessary for the waterproof test, resulting in more water being consumed than necessary.

Measures to solve the problem The waterproof test equipment installed in the test room where automobile waterproof tests are carried out is applied to all parts of the body of small car models and most of the bodies of large car models brought into the test room. A main nozzle group was installed on the wall of the test room to spray water, and a main nozzle group was installed on the wall of the test room to spray water onto parts of the body of a large vehicle that cannot be sprayed with water. To perform spraying, a sub-nozzle group installed on the wall of the test room and one pump to supply water via a valve to the above-mentioned main nozzle group and sub-nozzle group, or separate pumps to the main nozzle group and sub-nozzle group. Two pumps are used to supply water, and if the car being brought into the test room is small, water will be sprayed only from the main nozzle group, and if the car is large, water will be sprayed from both the main nozzle group and the sub-nozzle group. In order to determine the vehicle type,
It consists of a light sensor for vehicle type identification, consisting of a light emitter and a light receiver, installed on both sides of the test room.

Function: Depending on the type of car to be tested, water is sprayed from only the nozzles necessary for the waterproof test for that car type, thereby minimizing the amount of water used and the capacity of the pump.

Embodiment FIG. 1 is a developed view showing an example of the arrangement of nozzles of a waterproof test device according to the present invention. 1a and 1b in the figure
are the first and second nozzle groups installed on the ceiling of the test room where the waterproof test equipment is installed, 2a and 2b are the third and fourth nozzle groups installed on the floor, and 3a and 3b are the nozzle groups on both sides. These are the fifth and sixth nozzle groups to be installed. Among the above nozzle groups, the first, third and fifth nozzle groups 1a, 2a, 3a
All parts of the body of small car type A and large car type B of the cars brought into the test room.
The mounting position is set such that water is sprayed onto most of the body of the nozzle group 1a,
2a and 3a constitute a main nozzle group A. Moreover, the second, fourth and sixth nozzle groups 1b, 2
b, 3b are the first,
The mounting position is set so that water is sprayed to the parts that are not sprayed by the third and fifth nozzle groups 1a, 2a, 3a, and each of the above nozzle groups 1b, 2b, 3b Thus, it constitutes sub-nozzle group B. Two pumps are used to supply water to each of the nozzle groups described above using pumps (not shown).
3a, and second, fourth and sixth nozzle groups 1b, 2
Water is supplied to the first, third and fifth nozzle groups 1a, 2a, 3a using valves, or water is supplied to the first, third and fifth nozzle groups 1a, 3b separately or discharged from a single pump.
and second, fourth and sixth nozzle groups 1b, 2b, 3
b and separately. In addition, there are second
As shown in the figure, an optical sensor 4 consisting of a light emitter and a light receiver is installed. Then, either a small car type A is brought into the test room and the light emitted from the projector enters the light receiver and the optical sensor 4 is turned on, or a large car type B is brought into the test room and the light emitted from the projector enters the light receiver The light is blocked by the body of vehicle type B, and the type of vehicle brought into the test room can be automatically determined depending on whether the optical sensor 4 is turned off.

In the above configuration, in order to perform a shower test using the waterproof test device according to the present invention, a car to be tested is brought into the test room, and the type of car is determined by the optical sensor 4. If the vehicle to be tested is a small vehicle type A, the first, third and fifth nozzle groups 1a, 2a,
A shower test is performed by spraying water only from the main nozzle group A configured by 3a. In addition, if the automobile is a large vehicle type B, water is sprayed from the main nozzle group A composed of the first, third and fifth nozzle groups 1a, 2a, and 3a, and at the same time water is sprayed from the second, fourth and sixth nozzles. A shower test is conducted with water being sprayed from sub-nozzle group B, which is composed of groups 1b, 2b, and 3b.

Effects of the invention As described above, the water spray test device according to the present invention divides the nozzles placed in the test room into a main nozzle group and a sub-nozzle group, and sprays water from only the necessary nozzle groups depending on the type of vehicle brought into the test room. In addition, the vehicle type was determined using an optical sensor installed in the test room, and the water discharge from both nozzle groups was automatically controlled according to the above discrimination results. The amount of water used in the test device and the capacity of the pump can be minimized for each type of vehicle to be tested, and water and power consumption can be reduced compared to conventional test devices. In addition, as described above, the present invention is capable of automatically identifying the vehicle type and opening and closing the main nozzle group and sub-nozzle group accordingly, so that workers are not required to open and close both nozzle groups corresponding to the vehicle type. There is no need to set it up, and water spray tests can be performed efficiently.
