Wherein the first shielding structure 300 further seals the waterproof chamber between the front case 100 and the conductive adhesive key 200. The sealing structure of the application can prevent other liquids besides being waterproof.

In the using process, the front shell 100 is used for installing the conductive adhesive key 200 on one hand, and plays a role in blocking most of pollutants such as dust and/or water in the air on the other hand; the conductive adhesive key 200 is used to realize a signal transmission function between the user and the remote controller. Wherein, first protective structure 300 seals the clearance between preceding shell 100 and the conducting resin key 200, and then blocks pollutants such as water and/or dust between preceding shell 100 and conducting resin key 200, further promotes the sealing performance of remote controller to make the performance of remote controller be difficult to damaged. The application provides a seal structure, and then solve the poor problem of remote controller sealing performance in the use through setting up a seal structure.

As shown in fig. 1, the conductive adhesive key 200 includes a connecting portion 220 and a pressing portion 210. The connecting portion 220 is disposed on the circumferential side of the pressing portion 210; the first shielding structure 300 is disposed on the peripheral side of the connecting portion 220.

As shown in the schematic structural diagram of the sealing structure provided in fig. 1, the pressing portion 210 is formed by connecting a plurality of keys 211, and the circumferential side of the pressing portion 210 is a connecting portion 220. The key 211 on the conductive adhesive key 200 is clamped in the key hole on the front shell 100, and the connecting part 220 of the conductive adhesive key 200 is connected with the front shell 100 through the first protective structure 300. Wherein, connecting portion 220, press the setting of splenium 210 and first protective structure 300 integrated into one piece, reduced the clearance that each part exists in the assembling process, further improved seal structure's sealed effect.

In other embodiments, one key 211 is a pressing portion 210, and the circumference of the pressing portion 210 is a connecting portion 220. That is, a sealing structure is provided between each key 211 on the remote controller and the mounting hole of the front case 100 and is independent of each other.

In still other embodiments, a sealing structure is disposed around only the larger key 211 because there is a larger gap between the larger key 211 and the front case 100 and contaminants such as water and/or dust are easily introduced. The smaller key 211 is not provided with a sealing structure because of a smaller fitting gap.

As shown in fig. 1 and 2, the first guard structure 300 is a ring-shaped structure, and the axial cross-section of the first guard structure 300 is L-shaped. One end of the L-shape is connected to the connection part 220, and the other end of the L-shape is connected to the front case 100.

It should be noted that, as shown in the schematic structural diagram of the L-shaped first protective structure 300 of the sealing structure provided in fig. 2, the L-shaped structure forms a labyrinth structure between the ribs of the front shell 100, so that water and/or dust are not easy to enter the other side of the conductive adhesive key 200.

Further, an annular groove 310 is provided on a face of the first guard structure 300 opposite to the front case 100. An annular protrusion 110 is provided on a face of the front case 100 opposite to the connection part 220. The annular protrusion 110 is snapped into the annular groove 310.

It should be noted that, when the annular protrusion 110 is clamped in the annular groove 310, a sealing surface is formed between the outer wall of the annular protrusion 110 and the inner wall of the annular groove 310, and the assembly gap between the front shell 100 and the conductive adhesive key 200 is sealed, so that water, dust and other contaminants are not easy to enter the assembly gap.

As shown in fig. 2 and 4, the pressing portion 210 includes at least one key 211. A key housing 400 is sleeved on at least one key 211. The peripheral side of the key housing 400 is provided with a second protective structure 410.

As shown in the schematic structural view of the bezel 500 and the keys 211 in the sealing structure of fig. 4, the pressing portion 210 formed by connecting the plurality of keys 211 is a connecting portion 220 on the circumferential side of the pressing portion 210. The key housing 400 is sleeved on the plurality of keys 211, so that an assembly gap between the key housing 400 and the front case 100 is large, and a second protective structure 410 is disposed on the peripheral side of the key housing 400 for sealing the assembly gap.

In some embodiments, as shown in the structural schematic diagram of the decorative ring 500 and the keys 211 of the sealing structure in fig. 4, the plurality of keys 211 are connected to form the pressing portion 210, and the circumferential side of the pressing portion 210 is the connecting portion 220. A separate key housing 400 is sleeved over at least one key 211.

Further, the second guard structure 410 is a ring-shaped structure. The second guard structure 410 is located between the first guard structure 300 and the front case 100.

It should be noted that the second protection structure 410 is disposed in an annular shape, so as to seal a gap between the key housing 400 and the front case 100. The second protective structure 410 and the first protective structure 300 are mutually matched to form a labyrinth-type sealing structure, so that pollutants such as water and/or dust are effectively blocked, and the sealing performance of the sealing structure is improved.

As shown in fig. 4, a bezel 500 is provided in the mounting hole of the front case 100. The periphery of the bezel 500 is provided with a third protection structure 510. The third guard structure 510 is located between the second guard structure 410 and the front case 100. Further, the third prevention structure 510 is a hem provided along the peripheral side of the bezel 500.

Note that the bezel 500 serves to decorate one side and seals a gap between the front case 100 and the key 211. As shown in fig. 2 or 3, during the assembly process, a relatively large gap exists between the decorative ring 500 and the front housing 100 and between the decorative ring and the key 211, and the third protection structure 510 can seal the gap, so as to prevent water and/or dust and other contaminants from entering the gap, thereby further improving the sealing performance of the remote controller. A more complex labyrinth seal structure is formed among the third protective structure 510, the first protective structure 300, and the second protective structure 410, so as to block contaminants such as water and/or dust, and further improve the sealing performance of the seal structure.

As shown in fig. 3, a side of the first shielding structure 300 near the front case 100 is provided with a sealing protrusion; the sealing protrusion faces the assembly gap of the key housing 400 and the bezel 500.

It should be noted that, as shown in the schematic structural diagram of the sealing protrusion of the sealing structure provided in fig. 3, there is a fitting gap between the key housing 400 and the bezel 500. Sealed protruding this close fit clearance of orientation sets up, and then seals this close fit clearance, further promotes seal structure's sealing performance. As shown in fig. 3, the first guard structure 300 is double L-shaped. The double-L shape is an L shape with two heads connected in sequence, and is tightly matched with the key shell 400 and the decorative ring 500 to realize sealing. In some embodiments, the first protective structure 300 is shaped to cooperate with the key housing 400 and the bezel 500, so as to form a tight sealing structure with the key housing 400 and the bezel 500 while ensuring the normal use of the key 211.

As shown in fig. 1 and 4, a waterproof chamber is formed between the front case 100, the conductive adhesive key 200, and the first shielding structure 300. The front case 100 is provided with a water outlet 120 communicating with the waterproof chamber.

It should be noted that the water outlet 120 is detachably connected with a plug. During use, due to the sealing property of the sealing structure, water or other liquids entering the front case 100 are easily accumulated in the waterproof chamber between the front case 100 and the conductive adhesive key 200. In addition, the environment in the chamber is relatively closed, so that water collected in the waterproof chamber cannot be drained. When discharging water, the stopper is opened and water is poured out, and when in a normal state, the stopper is installed at the water outlet 120. In addition, can also wash the dust of gathering in the waterproof chamber through delivery port 120, prevent that more dust from piling up and producing the influence in waterproof strong indoor and then to the performance of conducting resin key 200.

Further, the first guard structure 300 is made of a silicone rubber material.
