Description

Rubber sealing element for high-strength automobile instrument element Technical Field The utility model relates to the technical field of automobile parts, in particular to a rubber sealing piece for a high-strength automobile instrument element. Background In the field of automobile manufacturing, automobile meters are used as key components of vehicles, and cover speedometer, tachometer, engine oil pressure meter, water temperature meter, fuel gauge, charging meter and the like, and stable operation of the automobile meters is very important. In order to ensure the sealing effect of the automobile instrument, the automobile instrument is required to be strictly sealed in order to effectively prevent air and dust from entering the instrument, and rubber materials become common choices of automobile instrument sealing elements by virtue of the characteristics of good elasticity, wear resistance and the like. However, the problem that the strength of the commercial common rubber sealing piece is low generally exists, the sealing piece is easy to stretch and deform due to insufficient strength in the assembly process, even cracks occur, leakage is caused, the sealing piece is difficult to bear the pressure of an automobile under the complex working condition, the service life is short, and the requirements of the automobile instrument on the high strength and the high reliability of the sealing piece cannot be fully met. Meanwhile, the automobile is in an all-weather state for a long time, and the running environment is complex and changeable, so that the rubber sealing piece is required to have high strength, good ozone aging resistance, atmospheric aging resistance, paint resistance, proper low temperature resistance and the like, and the influence of different environmental factors on the performance of the sealing piece is also required. Accordingly, it is an urgent need to develop a rubber seal for automobile instrument members which has high strength and excellent overall properties.
