Description

Technical Field

[0001] The utility model relates to the technical field of electronic products, in particular to a waterproof and dustproof structure of an electronic product. Background Art

[0002] With the increasing popularity and development of electronic products, people's requirements for electronic products are also diverse. For some outdoor sports enthusiasts, electronic products are becoming more and more popular. However, with the development trend of increasingly lightweight electronic products, the dust and water resistance of the USB charging port has become a weak link in mobile phones.

[0003] The utility model patent with authorization announcement number CN217428534U discloses a waterproof sealing structure for electronic products, including an upper cover and a lower cover that can be buckled together, a ridge fixed at the bottom edge of the upper cover, and a U-shaped groove opened on the lower cover. A sealing strip is provided in the U-shaped groove, and a groove is provided at the bottom of the sealing strip. When the upper cover and the lower cover are in a buckled state, the ridge is inserted into the U-shaped groove and presses against the sealing strip. The sealing strip is interference fit with the bottom of the U-shaped groove through deformation of the groove.

[0004] This technical solution solves the technical problem in the prior art that there is a gap between the waterproof sealing ring and the sealing groove and the waterproof sealing ring is not fixed by filling the gap between the ridge and the U-shaped groove with an arched sealing strip when the upper and lower covers are buckled together. The sealing strip of the utility model has a small sealing contact area with the ridge and has high waterproof performance. The shape of the sealing strip fills the gap between the ridge and the U-shaped groove, and the clamping ribs make it difficult for the sealing strip to fall off and drop, reducing the time and labor costs of rework. However, under this technical solution, the contact surface between the sealing strip and the shell is small, and the waterproof and dustproof effect is poor. At the same time, there are no hydrophobic holes to drain water immersed in the sealing strip to prevent corrosion of the sealing strip. In view of this, we propose a waterproof and dustproof structure for electronic products. Utility Model Content

[0007] According to the technical solution provided in the embodiment of the present application, a lower groove adapted to the sealing strip is opened along the edge of the top surface of the lower cover plate, and an upper groove corresponding to the position of the lower groove is opened along the edge of the bottom surface of the upper cover plate. The lower groove has the same size as the upper groove and is positioned opposite to each other.

[0008] According to the technical solution provided in the embodiment of the present application, several groups of mutually symmetrical clips are adhered and fixed on the vertical inner walls of the lower groove and the upper groove, and the vertical outer wall of the sealing strip is provided with clip grooves that are adapted to the size of the clips, are equal in number and have corresponding positions.

[0010] According to the technical solution provided in the embodiment of the present application, a plurality of hydrophobic grooves are provided on the side wall of the lower groove close to the outside, and the bottom ends of the hydrophobic grooves are connected to the water guide holes.

[0011] According to the technical solution provided in the embodiment of the present application, the ridges of the upper and lower sealing strips are staggered. When the lower cover plate and the upper cover plate are engaged, the ridges of the upper and lower sealing strips are staggered and fitted together, and the water-absorbing film is tightly fitted to the water film groove.
