Description

Technical Field

[0001] The utility model relates to the technical field of healthy smart rings, and in particular to a waterproof charging seat for a healthy smart ring. Background Art

[0002] As people's health awareness increases, the demand for smart health devices is also increasing. As a portable health monitoring, management and analysis device, health smart rings have the advantages of being comfortable to wear and having various health monitoring and analysis functions, and are favored by consumers.

[0003] However, the existing health smart ring includes an outer metal part, an inner metal part and a PCBA assembly. The charging stand on the PCBA assembly is installed on the PCBA assembly through the SMT process. When the PCBA assembly is assembled by SMT, it passes through a tin furnace with a temperature of 240 to 260 degrees Celsius. Due to the effects of cold shrinkage and thermal expansion, the isolation parts between the outer metal parts and the inner metal parts of the charging stand will have a certain deformation. After passing through the tin furnace, a gap will be generated between the isolation parts of the charging stand as a whole and the outer metal parts and the inner metal parts, thereby reducing the overall waterproof performance of the charging stand or even not having a waterproof function. In short, the waterproof performance stability of the waterproof charging stand of the existing health smart ring is poor or not waterproof. Utility Model Content

[0004] The utility model provides a waterproof charging stand for a health smart ring, which can solve the above problems.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0006] The utility model provides a waterproof charging seat for a health smart ring, comprising an outer metal piece and an inner metal piece installed on a PCB board, wherein the outer metal piece and the inner metal piece are isolated by epoxy resin, and the epoxy resin is attached to the inner wall of the outer metal piece and the outer wall of the inner metal piece.

[0007] As a further description of the above technical solution: the outer metal part is a cylindrical structure vertically fixed to the PCB board, the inner metal part is a stepped shaft structure coaxially arranged inside the outer metal part, and the epoxy resin is filled in the stepped annular gap between the outer metal part and the inner metal part.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] The charging stand is designed as three independent parts, namely the outer metal part, the inner metal part and the epoxy resin. The outer metal part and the inner metal part can be installed on the PCB board through the SMT process, and the epoxy resin can be filled between the outer metal part and the inner metal part by injection after SMT. Since the epoxy resin glue has excellent waterproof performance and structural stability, it ensures that the charging stand has excellent waterproof effect, stable performance and high production pass rate.
