Description

Technical Field

[0001] This utility model relates to the field of sealing structure technology, and in particular to a sealing structure for a charging door. Background Technology

[0002] Among various devices that require charging, the charging door is a key component protecting the charging interface and charging compartment. Its sealing structure directly affects the device's waterproof and dustproof performance, as well as charging safety. However, the sealing structure of current charging doors still has many technical shortcomings during long-term use, making it difficult to meet the requirements for long-term reliable operation of devices.

[0003] In existing charging door sealing structures, the rubber gasket is typically fixed directly to the edge of the charging compartment opening. When the charging door is opened, if the rubber gasket is fixed to the edge of the charging compartment opening, its exposed portion will directly contact external dust, sand, or be accidentally scratched, leading to wear, deformation, or even cracking of the rubber gasket surface. As a core component of the sealing structure, damage to the rubber gasket directly leads to a decrease in sealing performance and reduces the long-term reliability of the equipment. The sealing effect of existing charging door sealing structures mainly relies on the elastic deformation of the rubber gasket itself, achieving a seal through the natural compression of the rubber gasket when the cover closes. The compression force of the rubber gasket when the cover closes depends entirely on the cover's own fastening structure, which is limited and difficult to control precisely. Furthermore, the existing structure lacks auxiliary mechanisms to enhance the clamping force, further exacerbating the instability of the sealing effect and making it difficult to meet the sealing requirements of the equipment under complex operating conditions.
