[0050] The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0051] See also Figure 1-15 The utility model provides a technical solution: a high-sealing electric sliding cover, including an upper cover component 1 and a lower enclosure component 2.

[0052] The upper cover assembly 1 includes a bulletproof steel plate 11 , an upper frame 12 and two brackets 13 .

[0053] The bulletproof steel plate 11 is fixed to the upper frame 12 .

[0054] The two brackets 13 are symmetrically fixed on both sides of the upper frame 12 .

[0055] A limiting portion 123 is provided on both sides of one end of the upper frame 12 . The limiting portion 123 includes a limiting plate 1231 and a second roller 1232 . A locking hook 121 is provided on one end of the upper frame 12 away from the limiting portion 123 .

[0056] The bracket 13 is provided with a plurality of rollers 131 on the side surface close to the upper frame 12 for rotational cooperation.

[0057] The lower enclosure assembly 2 includes a lower enclosure frame 21 , two guide rails 22 and a driving unit 23 .

[0058] The upper frame 12 and the lower frame 21 are disposed correspondingly with their end faces facing each other.

[0059] A sealing strip 122 is provided on the end surface of the upper frame 12 close to the lower frame 21. The sealing strip 122 is set along the edge of the upper frame 12. Two racks 124 are provided on the end surface of the upper frame 12 close to the lower frame 21. A cylindrical gear 1241 is provided at both ends of the rack 124.

[0060] The two guide rails 22 are symmetrically fixed on both sides of the lower frame 21 , with one end of the guide rail 22 aligned with one end of the lower frame 21 , and the other end of the guide rail 22 extending from the side of the lower frame 21 .

[0061] The roller 131 is slidably mounted in the guide rail 22 .

[0062] A plurality of arc-shaped grooves 220 are provided on the bottom wall of the guide rail 22, one of which is located at the end position where the guide rail 22 is aligned with the end of the lower frame 21, and a limit pin 221 is provided at a position corresponding to the arc-shaped groove 220 on the top wall of the guide rail 22, and the limit pin 221 is protruded toward the arc-shaped groove 220.

[0063] A second limiting pin 211 is provided at a position corresponding to the limiting portion 123 of the lower frame 21 . The side of the second limiting pin 211 away from the upper frame 12 is configured as a curved surface, and the curved surface of the second limiting pin 211 abuts against the side surface of the second roller 1232 .

[0064] A slot 210 is provided on the side of the lower frame 21 at the position corresponding to the lock hook 121, and a boss 212 is provided on the wall of the slot 210 close to the upper frame 12. The boss 212 is chamfered at one end facing the slot 210, and the lock hook 121 is inserted into the slot 210 and fits tightly with the boss 212.

[0065] The driving part 23 includes a motor 231, a driving gear 232 and a rotating shaft 233. The motor 231 is fixed to the lower frame 21. The driving gear 232 is connected to the output end of the motor 231. The rotating shaft 233 is rotatably connected to the lower frame 21. Driven gears 2331 are provided at both ends of the rotating shaft 233. One of the driven gears 2331 is engaged with the driving gear 232, and the two driving gears 232 are respectively engaged with one of the racks 124.

[0066] By sliding the upper cover assembly 1 with the roller 131 in the guide rail 22 of the lower enclosure assembly 2 , the opening and closing of the electric sliding cover can be controlled.

[0067] During the closing process of the electric sliding cover, the roller 131 slides into the arc groove 220, and the upper cover assembly 1 is pressed on the lower enclosure assembly 2 due to its own gravity, and the sealing strip 122 is squeezed between the two, causing the sealing strip 122 to deform, thereby enhancing the sealing between the two.

[0068] When the electric sliding cover is about to be completely closed, the roller 131 at the end abuts against the limit pin 221. Due to the shape restriction of the limit pin 221, the roller 131 receives downward pressure during the continuous sliding process, that is, the entire upper cover assembly 1 is subjected to downward pressure, making the fit between the upper cover assembly 1 and the lower enclosure assembly 2 tighter, further strengthening the sealing between the two.

[0069] Moreover, when the electric sliding cover is about to be completely closed, the curved surfaces of roller 2 1232 and limit pin 211 abut against each other. As roller 2 1232 continues to slide, roller 2 1232 is subjected to downward pressure, that is, the entire upper cover assembly 1 is subjected to downward pressure. Since roller 1 131 and roller 2 1232 are respectively located at the two ends of the lower enclosure assembly 2, downward pressure can be generated on both ends of the lower enclosure assembly 2, which can further enhance the sealing between the lower enclosure assembly 2 and the upper cover assembly 1.

[0070] In addition, when the electric sliding cover is about to be fully closed, the lock hook 121 is inserted into the card slot 210, and is stuck in the card slot 210 along the rounded corner of the boss 212 and tightly abuts against the boss 212, thereby strengthening the locking effect between the upper cover assembly 1 and the lower enclosure assembly 2 and further enhancing the sealing between the two.

[0071] By connecting the motor 231 to electricity, it drives the driven gear 2331 engaged with it to rotate through the driving gear 232, and the driven gear 2331 drives another driven gear 2331 to rotate through the rotating shaft 233. The two driven gears 2331 drive the entire upper cover assembly 1 to move on the lower enclosure assembly 2 through the meshing action with the rack 124, thereby realizing the electric control of the opening and closing of the electric sliding cover.

[0072] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the scope of the present invention. The technical scope of this utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
