[0041] As Figure 2 And Figure 3, the first sealing member 30 has a head end 31 and a tail end 32, the head end 31 of the first sealing member 30 is detachably connected to the second connecting part 20, and the tail end 32 of the first sealing member 30 extends obliquely to the sealing surface 11, in other words, the line between the head end 31 and the tail end 32 of the first sealing member 30 is oblique to the sealing surface 11, in the embodiment, the cross section of the first sealing member 30 is linear along the extension direction from the head end 31 to the tail end 32, and the thickness of the head end 31 of the first sealing member 30 is greater than that of the tail end 32. When the first connecting part 10 and the second connecting part 20 are connected, the tail end 32 of the first sealing member 30 abuts against the sealing surface 11, and the first sealing member 30 is bent and deformed, and the deformed first sealing member 30 always has a tendency to move towards the sealing surface 11, so that the tail end 32 of the first sealing member 30 abuts against the sealing surface 11 tightly, and stable sealing between the first connecting part 10 and the second connecting part 20 is achieved.

[0042] The first sealing member 30 has a sealing surface 33, when the first sealing member 30 abuts against the sealing surface 11, the sealing surface 33 is arranged away from the sealing surface 11, and the sealing surface 33 is arranged obliquely to the sealing surface 11, when external air flow or water flow impacts the first sealing member 30 between the first connecting part 10 and the second connecting part 20, the air flow or water flow impacts the sealing surface 33, and the impact force of the air flow or water flow on the sealing surface 33 generates a component force perpendicular to the sealing surface 11, which increases the tendency of the tail end 32 of the first sealing member 30 to move towards the sealing surface 11, the extrusion force between the first sealing member 30 and the sealing surface 11 is greater, and the sealing performance is better, and when assembled, too much pressure does not need to be applied to the first connecting part 10 and the second connecting part 20 to avoid deformation of the two, and the two are simple to disassemble and convenient to maintain.

[0043] In order to achieve detachable connection of the first sealing member 30 and the second connecting part 20, the sealing structure further comprises a first connecting structure 40, the first connecting structure 40 comprises a connecting groove 41 and a connecting protrusion 42 which are fitted together, one of the connecting groove 41 and the connecting protrusion 42 is arranged on the second connecting part 20, and the other is arranged on the first sealing member 30. The connecting groove 41 and the connecting protrusion 42 are interference fit or glued connection, in the embodiment, the connecting groove 41 is arranged on the second connecting part 20, the head end 31 of the first sealing member 30 is provided with the connecting protrusion 42, and the connecting protrusion 42 is an integral structure with the first sealing member 30, which can be made of rubber or silicone material, the first connecting structure 40 can realize quick assembly of the first sealing member 30, without using additional fasteners, which is beneficial to reduce the cost of equipment.

[0044] Further, as Figure 5The sealing structure further comprises a skeleton 50 in the shape of a ring, the first end 31 of the first sealing member 30 is connected to the skeleton 50, and the skeleton 50 can support the soft first sealing member 30, so that the first sealing member 30 can also maintain a ring shape like the skeleton 50, which helps the first sealing member 30 to be efficiently assembled to the second connecting portion 20.

[0046] As Figure 4 , the difference between this embodiment and embodiment 1 is that the extension track of the cross section of the first sealing member 30 in the direction from the first end 31 to the second end 32 is a curve, and the opening direction of the curve is towards the sealing surface 11. The first sealing member 30 of this structure can improve the extrusion force between the second end 32 and the sealing surface 11 compared with the first sealing member 30 of embodiment 1, so as to improve the sealing performance.

[0047] Embodiment 3

[0048] As Figure 5 and Figure 6 , the difference between this embodiment and embodiment 1 is that the sealing structure further comprises a sealing assembly, the sealing assembly comprises two first sealing members 30 as described above, the first ends 31 of the two first sealing members 30 are connected and the connection between the two first sealing members 30 is connected to the second connecting portion 20, and the second ends 32 of the two first sealing members 30 are arranged opposite to each other and extend in opposite directions, so that the structure formed by the connection of the two first sealing members 30 has a V-shaped cross section. When the first connecting portion 10 and the second connecting portion 20 are connected, the second ends 32 of the two first sealing members 30 abut against the sealing surface 11, and the two first sealing members 30 are both bent and deformed. The two first sealing members 30 can further improve the sealing performance.

[0049] Specifically, Figure 5 , the connection between the two first sealing members 30 of the sealing assembly is provided with a connecting groove 41, and correspondingly, the second connecting portion 20 is provided with a connecting protrusion 42, and the sealing assembly is detachably connected to the second connecting portion 20 through the first connecting structure 40.

[0050] As Figure 6 , the connection between the two first sealing members 30 of the sealing assembly is provided with a connecting protrusion 42, and correspondingly, the second connecting portion 20 is provided with a connecting groove 41, and the sealing assembly is detachably connected to the second connecting portion 20 through the first connecting structure 40.

[0051] Embodiment 4

[0052] As Figure 2 and Figure 3The difference between the embodiment and the embodiment 1 is that the sealing structure further comprises a third connecting part 60 and a second sealing part 70 located between the second connecting part 20 and the third connecting part 60, wherein the first connecting part 10 can be a lamp plate of a display module, the second connecting part 20 can be a bottom shell frame supporting the lamp plate, and the third connecting part 60 can be a back cover covering the bottom shell. The second sealing part 70 is used to provide sealing between the second connecting part 20 and the third connecting part 60.

[0053] The second sealing part 70 comprises a mounting part 71 and a movable block 72, the mounting part 71 is arranged on the second connecting part 20, and the movable block 72 is used to abut against the third connecting part 60. The mounting part 71 has a first end and a second end arranged oppositely, and the movable block 72 is arranged on the first end of the mounting part 71. When the second connecting part 20 and the third connecting part 60 move towards each other, the movable block 72 winds the mounting part 71 to form a winding sealing block 73, and the two sides of the winding sealing block 73 abut against the mounting part 71 and the third connecting part 60 respectively. Specifically, the movable block 72 winds the first end of the mounting part 71 to the middle part of the mounting part 71 to form the winding sealing block 73, and the two sides of the winding sealing block 73 abut against the second end of the mounting part 71 and the third connecting part 60 respectively.

[0054] Further, the mounting part 71 comprises a fixed block 711 and a connecting segment 712 connected with each other, the connecting segment 712 is provided with the movable block 72, and the fixed block 711 is arranged on the second connecting part 20 and provides a fixed basis for the second sealing part 70.

The winding sealing block 73 and the fixed block 711 have a rolling motion, which produces rolling friction. At the same time, the winding sealing block 73 and the third connecting part 60 also have a rolling motion, which also produces rolling friction. Compared with the sliding friction produced by the existing sealing structure, the rolling friction has smaller friction force. This makes the movement resistance brought by the winding sealing block 73 to the fixed block 711 and the third connecting part 60 smaller. In other words, the force required to drive the second connecting part 20 and the third connecting part 60 to move towards each other is smaller.

[0055] With the continuous movement of the second connecting part 20 and the third connecting part 60 towards each other, the cross-sectional area of the winding sealing block 73 gradually increases, and the two sides of the winding sealing block 73 abut against the fixed block 711 and the third connecting part 60 respectively. Under the condition that the distance between the second connecting part 20 and the third connecting part 60 remains unchanged, the extrusion force between the winding sealing block 73 and the fixed block 711 and the extrusion force between the winding sealing block 73 and the third connecting part 60 gradually increase, which can provide better sealing for the second connecting part 20 and the third connecting part 60.

[0056] Embodiment 5

[0058] There are various ways of mutual clamping between the clamping block 82 and the clamping groove 81, one of which is that, as Figure 7 , the end of the clamping block 82 is provided with a clamping protrusion 821 for detachably embedding in the clamping groove 81, and the clamping protrusion 821 can be embedded in the clamping groove 81. The second is that, as Figure 8 , the clamping block 82 is provided with a connecting hole 822, which is preferably a through hole, and the inner wall of the clamping groove 81 is provided with a limiting protrusion 811, which is detachably embedded in the connecting hole 822 when the clamping block 82 extends into the clamping groove 81.
