Description

Technical Field

[0001] This utility model belongs to the technical field of automotive parts testing devices, and more specifically, it relates to an automotive suspension pad salt spray test chamber. Background Technology

[0002] As a key connecting component between the powertrain and the vehicle body, automotive suspension pads primarily function to isolate engine vibration and reduce interior noise. However, they are constantly exposed to the complex environment of the vehicle chassis and are susceptible to corrosion from rainwater, salt, and other corrosive media, leading to performance degradation. Therefore, salt spray testing is necessary to assess their corrosion resistance. Currently, most existing salt spray test chambers cannot effectively recover and reuse the droplets generated during the salt spray test in real time. This requires subsequent centralized collection and treatment of the droplets, with the equipment directly discarding the recovered liquid. This not only wastes salt water resources but also necessitates additional treatment of the salt-containing waste liquid, increasing testing costs and environmental pressure. Furthermore, many salt spray test chambers employ a single top nozzle or fixed nozzles on both sides, resulting in a unidirectional salt spray direction and preventing sufficient contact between the salt spray and the suspension pads during testing. Utility Model Content

[0010] The automotive suspension pad salt spray test chamber provided by this utility model has the following beneficial effects: 1. This utility model achieves stable clamping and precise bearing of the automotive suspension pad through the coordinated cooperation of the assembly block and the test frame. It accurately positions the suspension pad in the side area of ​​the delivery pipe and the atomizing nozzle, providing a stable sample posture basis for subsequent directional salt spraying, avoiding spray deviation caused by sample offset during the test, and ensuring that the salt spray can directly act on the key test surface of the sample.

[0011] 2. The rotating support block and the rotating carrier block of this utility model rotate together to cover the top of the test chamber with the drive test cover, thereby achieving a tight seal of the test space, preventing salt spray from leaking out during the test, and avoiding interference from external airflow with the salt spray environment inside the chamber.

[0012] 3. The extraction device of this utility model efficiently extracts the test liquid through the extraction pipe and the control valve pipe. Then, the test liquid is stably transported to the delivery pipe through the rotating pipe. Finally, the atomizing nozzle transforms it into salt spray and sprays it onto the suspended pad. The drive motor drives the drive tooth block to rotate through the meshing of the drive tooth block and the transmission tooth chain. In turn, the transmission tooth block rotates the support cylinder and drives the rotating carrier cylinder to rotate. During the rotation of the carrier cylinder, it can drive the delivery pipe to move in a circular path around the suspended pad, so that the atomizing nozzle can spray the suspended pad with salt spray from multiple angles. This ensures that the salt spray evenly and fully covers the sample surface and key structures, and greatly improves the comprehensiveness of the contact between the salt spray and the sample. 4. This utility model uses a guide carrier to support and guide the recovery frame. The recovery frame can accurately receive the salt spray droplets that condense and drip during the test, avoiding the pollution and waste of resources inside the test chamber caused by the random scattering of droplets. The recovery pipe and control valve pipe enable the extraction device to recover and extract the salt spray droplets collected inside the recovery frame for reuse. Attached Figure Description
