  • Patent number: 11612074
    Abstract: A waterproofing structure is disposed between a first assembling component and a second assembling component of an electronic device. The second assembling component is detachably installed on the first assembling component. The waterproofing structure includes a sealing component, an abutting component and a sliding component. The sealing component is located between the first assembling component and the second assembling component. The abutting component is fixed on the second assembling component. The sliding component is slidably installed on the first assembling component. When the sliding component slides along a first direction, the sliding component forces the abutting component to drive the second assembling component to move toward the first assembling component, so that the sealing component is pressed by the first assembling component and the second assembling component.
