Title:
LATERAL ACCELERATION SENSOR FOR MULTIPLE-UNIT TRAIN AND POTTING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/067534
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of potting. Provided are a lateral acceleration sensor for a multiple-unit train and a potting method therefor. Specifically, the method comprises four independent potting steps, wherein the angle of a sensor, the potting position and potting limitation during potting, and treatment modes for standing are defined, such that bubbles possibly generated during potting processes are avoided to the utmost extent; namely, the probability of generating bubbles during potting processes of lateral acceleration sensor products is minimized or even no bubble is generated, thereby avoiding the generation of bubbles in metal casings of lateral acceleration sensors after the potting is completed, thus solving the problem that bubbles present in resin nearby components due to anomalies of potting processes cause damages to welding spots of components and thus eventually lead to open circuits of components, reducing the probability of failures of lateral acceleration sensors and effectively prolonging the service life of lateral acceleration sensors.
