[0026] In order to have a further understanding of the purpose, technical effects and technical means of the present invention, it is described in detail as follows in conjunction with the accompanying drawings.

[0027] See also Figures 1 to 4 As shown, the present invention provides a power interface sealing structure, which is applied to a notebook computer, and the power interface sealing structure includes:

[0028] The sealing cover 100 includes a fixed end 101 and a movable end 102 rotating around the fixed end 101, wherein the fixed end 101 is fixed to the lower shell 10 of the laptop computer, and the movable end 102 has a cylindrical protrusion 103 on the fitting surface facing the power interface 11, and the cylindrical protrusion 103 is inserted into the power interface 11 to seal the power interface 11. When the power interface 11 needs to be connected to a power cord, the movable end 102 of the sealing cover 100 is pulled open to separate the cylindrical protrusion 103 from the power interface 11, and the side surface of the movable end of the sealing cover 100 has a card slot 104;

[0029] The sliding member 200 is movably disposed in the lower shell 10 of the laptop computer. The sliding member 200 has a card block 201 and a push block 202. The card block 201 is disposed toward the card slot 104. The push block 202 is exposed from the lower shell 10 of the laptop computer. The push block 202 is pushed to drive the sliding member 200 to slide, so that the card block 201 on the sliding member 200 is stuck in the card slot 104 or exits the card slot 104. Specifically, when the card block 201 is stuck in the card slot 104, the card block 201 locks the card slot 104 to prevent the cylindrical protrusion 103 of the sealing cover 100 from being separated from the power interface 11; when the card block 201 exits the card slot 104, the card block 201 no longer locks the card slot 104, and the cylindrical protrusion 103 of the sealing cover 100 can be separated from the power interface 11.

[0030] like Figure 2 As shown, the fixed end 101 of the sealing cover 100 is curved on the outside to match the shape of the laptop shell, and the fixed end 101 has a fixed block 104 on the inside. The fixed block 104 is embedded in the lower shell 10 of the laptop, and a screw hole 105 is provided in the fixed block 104 for screws to be locked therein. The fixed block 104 enhances the strength of the connection between the fixed end 101 of the sealing cover 100 and the lower shell 10 of the laptop. The movable end 102 of the sealing cover 100 extends outward along the thickness direction of the lower shell 10 of the laptop and has two protrusions 106. The movable end 102 is rotated by moving the protrusions 106, so that the cylindrical protrusion 103 can be quickly pulled out of the power interface 11, which is easy to operate.

[0031] The sealing cover 100 is made of rubber and is not easily deformed, and the cylindrical protrusion 103 forms an interference fit with the power interface 11 to achieve tight sealing, waterproofing, and moisture-proofing.

[0032] like Figure 3 and Figure 4 As shown, the side of the sliding member 200 away from the push block 202 has at least one sliding bar 203, and the sliding bar 203 is arranged along the moving direction of the sliding member 200. The sliding bar 203 reduces the friction between the sliding member 200 and the laptop computer, making it easier for the sliding member 200 to slide. Preferably, three sliding bars 203 are arranged on the sliding member 200.

[0033] In a preferred embodiment, the sliding member 200 has a positioning bar 204 on one side away from the push block 202. The positioning bar 204 is made of rubber. The positioning bar 204 is set in a direction perpendicular to the moving direction of the sliding member 200. The laptop computer has a positioning groove 12. When the sliding member 200 moves, the positioning bar 204 is stuck in the positioning groove 12 or comes out of the positioning groove 12. Specifically, when the push block 202 is pushed so that the block 201 of the sliding member 200 is stuck in the groove 104 of the sealing cover 100, the positioning strip 204 is disengaged from the positioning groove 12, and the side wall of the positioning groove 104 plays a positioning role to prevent the sliding member 200 from returning; similarly, when the push block 202 is pulled back so that the block 201 of the sliding member 200 is no longer stuck in the groove 104 of the sealing cover 100, the positioning strip 304 is stuck in the positioning groove 12, and the side wall of the positioning groove 12 plays a positioning role to prevent the sliding member 200 from returning.

[0034] In order to further position the sliding member 200, a positioning hole 205 is opened on the sliding member 200, and the laptop computer has a positioning column 13, which is arranged in the positioning hole 205. When the sliding member 200 moves, the positioning column 13 moves in the positioning hole 205. Furthermore, the positioning column 13 can be a screw.

[0035] like Figure 5 As shown in , the lower shell 10 of the laptop computer has a through hole 14, the push block 202 is exposed from the through hole 14, and the push block 202 reciprocates in the through hole 14, and the through hole 14 can be square. Furthermore, the lower shell 10 of the laptop computer is provided with a "clamp" mark 15 and an "open" mark 16 on both sides of the through hole 14, the "clamp" mark 15 indicates that the block 201 of the sliding member 200 is clamped in the groove 104 of the sealing cover 100, and the sealing cover 100 cannot be opened, and the "open" mark 16 indicates that the block 201 of the sliding member 200 is no longer clamped in the groove 104 of the sealing cover 100, and the movable end 102 of the sealing cover 100 can be opened, which is convenient for the staff to operate.

[0036] See also Figure 6 and Figure 7 As shown, when the power interface sealing structure of the present invention is used, when the laptop computer does not need to be connected to a power cord, the cylindrical protrusion 103 of the sealing cover 100 is inserted into the power interface 11, and the push block 202 of the sliding member 200 is pushed toward the "clamping" mark 15, so that the clamping block 201 is clamped in the groove 104 of the sealing cover 100, and the sealing cover 100 is locked; when the laptop computer needs to be connected to a power cord, the push block 202 of the sliding member 200 is pulled back toward the "opening" mark 16, and the clamping block 201 is no longer clamped in the groove 104 of the sealing cover 100, and the movable end 102 of the sealing cover 100 is opened, and the power cord can be inserted.

[0037] In summary, the power interface sealing structure of the present invention is provided with a sealing cover 100 and a sliding member 200. The cylindrical protrusion 103 of the sealing cover 100 is used to seal the power interface 11 of the laptop computer, thereby playing a sealing role. By pushing the push block 202 on the sliding member 200, the card block 201 is driven to be carded in the card slot 103 of the sealing cover 100, thereby clamping the sealing cover 100 to prevent the sealing cover 100 from loosening and falling out of the power interface 11, thereby avoiding loosening during the repeated opening and closing of the sealing cover 100.

[0038] It should be pointed out that the present invention is not limited to the above-mentioned implementation modes, and any simple modifications, equivalent changes and modifications made to the above-mentioned embodiments by any technician familiar with the profession based on the technical solution of the present invention fall within the protection scope of the present invention.
