Abstract
Description
Technical Field
[0001] This utility model relates to the field of automobile rain testing technology, specifically to a device for measuring rainfall during automobile rain testing. Background Technology
[0002] The automotive rain test rainfall measurement device is a specialized testing equipment designed to simulate natural rainfall environments and quantify the intensity and distribution characteristics of rainfall during automotive rain tests. It is primarily used in the sealing testing of complete vehicles or components in the automotive manufacturing industry. By accurately measuring key parameters such as rainfall volume, rainfall uniformity, and raindrop impact force during the test, it ensures that the rain test conditions meet relevant standards (such as ISO, SAE, and national standards), thereby verifying the waterproof performance of the vehicle body, doors, windows, seals, and other components.
[0003] Existing vehicle rain test rainfall measurement devices often employ complex valves or knobs for flow regulation, resulting in low adjustment accuracy and cumbersome operation. This makes it difficult to quickly and accurately change the water flow rate to simulate rainfall of different intensities. Furthermore, some devices suffer from insufficient durability of key components such as air pipes, leading to corrosion and aging after prolonged use, thus shortening the device's lifespan. Therefore, we propose a new vehicle rain test rainfall measurement device. Utility Model Content

[0007] A measuring cylinder, wherein a pipe connector is fixedly installed on the top surface of the measuring cylinder, the bottom end of the pipe connector penetrates the top surface of the measuring cylinder and extends into the interior, a nozzle is fixedly installed on the bottom end of the pipe connector, a first quick plug is fixedly installed on the top end of the pipe connector, and a first air tube is fixedly installed on the top surface of the first quick plug.
[0008] The second air tube is located on one side of the first air tube. A second quick plug is fixedly installed at one end of the second air tube, and a nozzle clip seat is fixedly installed on one side of the second quick plug.
[0009] An adjustment component is disposed within the first trachea and is used to adjust the flow rate.
[0010] Preferably, the adjustment assembly includes an annular mounting bracket disposed inside the first air tube. Both sides of the annular mounting bracket are fixedly connected to the outer side wall of the first air tube. An annular rotating block is disposed inside the annular mounting bracket. The outer side wall of the annular rotating block is slidably connected to the inner side wall of the annular mounting bracket. A hexagonal groove is formed on one side of the annular rotating block. Multiple sliding plates are slidably installed in the hexagonal groove. Limiting rods are fixedly installed on one side of each of the multiple sliding plates. Multiple limiting grooves are formed on one side of the annular mounting bracket. The multiple limiting rods are slidably installed in the multiple limiting grooves respectively.
[0011] Preferably, the adjustment assembly further includes a handle, which is fixedly installed on the outer side wall of the annular rotating block. The outer side wall of the annular mounting bracket is provided with a sliding groove, and the handle is located in the sliding groove. The outer side wall of the handle is slidably connected to the inner side wall of the sliding groove.
[0012] Preferably, a connector is fixedly installed at one end of the first trachea and the second trachea respectively, and the same connecting pipe is fixedly installed between the two connectors. The first trachea, the second trachea, the two connectors and the connecting pipe are connected.

[0015] Preferably, the outer wall of the tracheal switch is provided with anti-slip texture.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This vehicle rain test rainfall measurement device connects to an external water source via a nozzle clip at one end of a second air pipe. Water flows through the second air pipe, connector, and connecting pipe into the first air pipe. An air pipe switch on the connecting pipe controls the on / off state of the entire air circuit, facilitating operation. By sliding the handle within the groove of the annular mounting bracket, the annular rotating block rotates, causing the sliding plate to slide within the hexagonal groove. The limiting rod moves accordingly within the limiting groove, thereby changing the flow cross-section within the first air pipe and adjusting the flow rate. The adjusted water flows through the first quick connector and pipe joint into the nozzle at the top of the measuring cylinder, spraying out and falling into the measuring cylinder. Operators can measure the rainfall during the rain test by reading the water volume in the measuring cylinder. The stainless steel first and second air pipes ensure the device's durability, while the anti-slip texture on the outside of the air pipe switch enhances ease of operation.
