Technical Field

[0001] The utility model relates to the technical field of ECU testing, and more specifically to a tool for measuring the air tightness of an ECU cover. Background Art

[0002] In the automotive industry, the electronic control unit (ECU) is one of the key components of the vehicle, responsible for controlling multiple key functions such as the engine, transmission, and brake system. As a protective component of the ECU, the design and manufacturing quality of the ECU cover directly affects the reliability and performance of the ECU. The ECU cover needs to have good sealing performance to prevent moisture, dust, and other contaminants from entering the ECU and affecting its normal operation.

[0003] During the production process of the current new product ECU cover, customers have put forward the requirement of air tightness. In response to this requirement, special tooling needs to be made to seal its surface to ensure that the inside meets the air tightness test requirements.

[0004] Traditional ECU cover testing methods usually rely on manual operations, which have problems such as low testing efficiency, low accuracy, and poor repeatability. In addition, due to the lack of standardized testing tools, it is difficult to ensure consistent testing standards between different batches of products, which may lead to unstable product quality.

[0005] To this end, the present application proposes a tool for measuring the air tightness of an ECU cover to solve the above-mentioned problems. Utility Model Content

[0010] Furthermore, a sealing gasket is provided at the joint between the contoured base and the ECU cover.

[0011] Through the above technical solution, gas leakage can be effectively prevented to ensure the accuracy of the test results; the ECU cover can also be protected during the pressing process.

[0012] Furthermore, a connecting rod is provided on the top of the contoured top cover, and the contoured top cover is fixedly connected to the top plate via the connecting rod. A flat spring is sleeved on the connecting rod between the top of the contoured top cover and the bottom of the top plate.

[0013] Through the above technical solution, appropriate elastic pressure is provided to ensure the sealing between the contoured top cover and the ECU cover, while avoiding damage to the ECU cover due to excessive pressure.

[0014] Furthermore, the contoured top cover is detachably provided with an airtight rod corresponding to the top hole of the ECU cover, and an airtight pad is provided at the bottom of the airtight rod.

[0015] Through the above technical solution, the air tightness test can be accurately performed on the specific part of the ECU cover, thereby improving the pertinence and accuracy of the test.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] (1) Compared with the original technology, this tooling can effectively improve the stability and accuracy of the airtightness of parts, ensure that parts can be measured according to customer requirements, and ensure that qualified products can flow out.

[0018] (2) The setting of the sealing pad and the airtight rod enhances the sealing performance during the test and reduces the possibility of gas leakage, thereby ensuring the accuracy of the test results. BRIEF DESCRIPTION OF THE DRAWINGS
