Description

Technical Field

[0001] The utility model relates to the technical field of automobile test benches, in particular to an automobile static detection rollover test bench. Background Art

[0002] The vehicle static rollover test bench is a device specifically designed to evaluate the leak tightness and safety of a vehicle's fuel system under extreme conditions. By simulating the actual conditions of a vehicle in a rollover or tilt, the test bench helps detect leaks or damage in fuel lines, tanks, and connectors.

[0003] A search of the prior art revealed a Chinese patent application for a "Static Rollover Test Bench for Fuel System Integrity Testing," application number 201620406514.1. This patent primarily includes a transmission mechanism for driving the rotating platform, a rollover platform, a frame, and a control device for controlling the transmission mechanism. It also includes a locking mechanism comprising a drive motor, a locking disc, a connecting rod, a connecting rod support rod, and a locking pin shaft. The locking disc is fixedly connected to the rotating shaft of the rollover platform and has four locking holes at equal circumferential angles. A sliding groove is provided below the frame bearing, within which the locking pin shaft resides. The connecting rod is hingedly connected to the locking pin shaft and the drive motor at each end, and the connecting rod support rod is hingedly connected to the middle of the connecting rod. While this utility model automatically engages a mechanical locking mechanism at 90°, 180°, 270°, and 360° positions, ensuring the safety of the test process, the entire test process can be automated with a simple operation. However, in a static vehicle rollover test bench, the installation of an oil collection system is crucial for accurately collecting and measuring oil. Oil can accumulate in different areas of the oil pan. After the oil pan is set up to collect the oil and then discharge it through the oil collection hole, some oil may remain in the pan, preventing it from being fully collected near the oil collection hole. This affects effective oil collection and the accuracy of test results. Therefore, the present invention provides a static vehicle rollover test bench to address the problems raised in the aforementioned background technology. Utility Model Content
