[0025] Embodiment 1

[0026] With reference to Figures 1-3 The present application provides a shell assembly, which comprises a first shell 1 and a second shell 2 detachably connected with the first shell 1, one side of the first shell 1 facing the second shell 2 is provided with a groove 11, one side of the second shell 2 facing the first shell 1 is provided with a protrusion 21 adapted to cooperate with the groove 11, the groove 11 is provided with a sealant layer 3 formed by curing liquid glue and detachable from the groove 11, when the first shell 1 and the second shell 2 are connected, the protrusion 21 is arranged in the groove 11 in cooperation, and the sealant layer 3 is used to fill the gap between the groove 11 and the protrusion 21 to realize the sealed connection of the connecting part.

[0027] The shell assembly described above, by setting the groove 11 and the sealant layer 3 formed by the liquid solidification in the groove 11, the sealant layer 3 is not affected by the production tolerance of the special-shaped shell, and can be closely attached to the groove 11 of the first shell 1 and completely matched with the shape of the groove 11 of the special-shaped shell, improve the sealing and waterproof performance of the shell connection, and do not need to produce a separate sealing layer matched with the shape of the special-shaped shell. In addition, the prior art also connects the first shell 1 and the second shell 2 of the special-shaped shell by using high-viscosity glue to realize the sealing and waterproof connection of the first shell 1 and the second shell 2, but using high-viscosity glue to connect the first shell 1 and the second shell 2 causes the first shell 1 and the second shell 2 to be unable to be disassembled and repaired, and when the first shell 1 and the second shell 2 are disassembled for repair, the first shell 1 and the second shell 2 may be damaged due to the existence of high-viscosity glue. The present application uses low-viscosity sealant layer 3 which can be disassembled from the groove 11, which can realize the dismountable connection of the first shell 1 and the second shell 2 at the connection part while waterproof sealing, when the operator needs to disassemble the first shell 1 and the second shell 2 for repair, after disassembling the first shell 1 and the second shell 2, the solidified sealant layer 3 can be directly taken out from the groove 11.

[0028] In some embodiments, referring to Figures 1-3 , the first shell 1 and the second shell 2 are connected to form an internal hollow shell, the groove 11 is formed along the edge of the side of the first shell 1 facing the second shell 2 to form a first-end-to-end groove, and the shape of the protrusion 21 matches the groove 11. For the internal hollow shell, the groove 11 is arranged as a first-end-to-end groove to enable the first shell 1 and the second shell 2 to be completely sealed and connected. Specifically, it can be understood that the shape of the groove 11 is determined by the shape of the connection part of the first shell 1 and the second shell 2. If the connection part of the first shell 1 and the second shell 2 is a closed first-end-to-end shape, the groove 11 is also a first-end-to-end ring groove. Through the cooperation of the groove 11 and the sealant layer 3 formed by the solidification of the liquid glue and dismountable from the groove 11, the sealed connection of the connection part of the first shell 1 and the second shell 2 is realized.

[0029] In some embodiments, referring to Figure 1 , the sealant layer 3 is a first-end-to-end glue ring after being taken out of the groove 11. When connecting the first shell 1 and the second shell 2, the present application first applies low-viscosity sealant in the groove 11, then aligns the protrusion 21 of the second shell 2 with the groove 11 of the first shell 1 to connect the second shell 2 and the first shell 1, and the sealant in the groove 11 solidifies to form a sealant layer 3 after a certain period of time. When repair is needed, the first shell 1 and the second shell 2 are disassembled, and the solidified sealant layer 3 is a sealant ring that can be directly taken out of the groove 11. The operator can directly take out the sealant ring, and after the repair is completed, the first shell 1 and the second shell 2 can be reassembled by applying sealant.

[0030] In some embodiments, the sealant layer 3 is formed by curing a curable liquid silicone. Specifically, the glue used to make the sealant layer 3 is a low-viscosity liquid silicone with waterproof properties. Further, the liquid silicone used to make the sealant layer 3 is an organic silicone potting compound.

[0031] In some embodiments, referring to Figures 1-3 , at least one edge of the face of the first shell 1 facing the second shell 2 is an arc-shaped edge 12 concave in the direction away from the second shell 2. Specifically, the two opposite side edges of the face of the first shell 1 facing the second shell 2 are arc-shaped edges 12 concave in the direction away from the second shell 2. The connecting part of each face of the first shell 1 is provided with an arc-shaped chamfer, and the connecting part of each face of the second shell 2 is also provided with an arc-shaped chamfer. By providing the arc-shaped chamfer, the appearance of the shell is improved while the safety is improved.

[0032] In some embodiments, referring to Figure 3 When the first shell 1 and the second shell 2 are assembled, the protrusion 21 is located in the groove 11, and there is a gap 4 between the first shell 1 and the second shell 2. When assembling the first shell 1 and the second shell 2, the operator can apply more sealant in the groove 11, so that when the second shell 2 and the first shell 1 are assembled, the sealant in the groove 11 not only fills the gap between the groove 11 and the protrusion 21, but also can fill the gap 4 between the first shell 1 and the second shell 2, so that the contact area between the sealant layer 3 and the first shell 1 and the second shell 2 is larger, and the possibility of failure of the sealant layer 3 is reduced.
