[0021] Referring to Figures 1-6 The technical scheme adopted in the specific embodiment is: it includes watch body 1, the back surface of the watch body 1 is provided with watch back cover 2, a plurality of charging columns 3 are arranged on the watch back cover 2, the inside of the watch back cover 2 is provided with charging FPC 4, the middle part of the charging FPC 4 is provided with FPC charging via hole pad 5, the charging column 3 passes through the FPC charging via hole pad 5 and is welded and fixed, in the embodiment, by directly welding the charging column on the FPC charging via hole pad, the charging column and the charging FPC form an integral whole, thereby effectively improving the conductive effectiveness of the charging column, while the traditional structure or adopts elastic pin welding or adopts contact surface welding, the virtual welding condition is prone to appear in the assembly process, not only the component needs rework condition appears, but also the normal charging use of the equipment is affected, and the integrated welding structure of the embodiment not only is not prone to rework condition, but also cannot charge condition caused by poor contact of the welding piece does not appear in the long-time use process.

[0022] More specifically, the charging FPC 4 is provided with FPC reinforcing steel sheet 6 away from the side of the watch back cover 2, by setting the FPC reinforcing steel sheet on the side close to other components in the watch body, not only can the charging FPC component be protected from being collided by other components, but also the overall strength of the charging FPC is improved.

[0023] More specifically, the FPC reinforcing steel sheet 6 is provided with a welding groove 61 at the corresponding position of the charging column 3. In this embodiment, the FPC reinforcing steel sheet not only plays a protective role, but also is provided with a welding groove at the corresponding position of the charging column. The welding groove position corresponds to the FPC charging via pad position. The charging column penetrates into the welding groove from the FPC charging via pad for welding and fixing. The welding point is protected in the welding groove and cannot be exposed, thereby further improving the effectiveness of welding.

[0024] More specifically, the FPC charging via pad 5 is provided with a via 51 at the center. The via matches the charging column and has a gap, which is beneficial to increase the welding area and improve the welding firmness.

[0025] More specifically, the welding groove 61 has an inner diameter larger than the outer diameter of the via 51. The welding groove has a larger space, which can better perform welding operation and improve the welding firmness.

[0026] More specifically, the charging column 3 has a three-segment structure. The outermost end of the charging column 3 is a contact charging end. The middle segment of the charging column 3 is a fixed end. The bottom of the charging column 3 is a welding end. The outer diameter of the contact charging end is larger than the outer diameter of the fixed end. The outer diameter of the fixed end is larger than the outer diameter of the welding end. In this embodiment, the charging column is divided into three parts. The outermost end is the contact charging end, which is restrained by the matching groove of the watch back cover and cannot be pressed into the watch body, so as to ensure that the internal elements are not damaged and the welding position is not damaged.

[0027] More specifically, the contact charging end surface of the charging column 3 is provided with a positioning groove 31. In this embodiment, the contact charging end surface of the charging column is provided with a positioning groove which cooperates with the charging spring needle of the charging seat for charging. The traditional contact structure is mostly planar contact. The end of the charging spring needle is mostly arc surface structure. The contact surface is small and prone to poor contact. The cooperation of the positioning groove in this embodiment and the charging spring needle greatly increases the contact area, thereby effectively improving the connection stability during charging and ensuring the charging effect.

[0028] The working principle of the utility model discloses: when assembling the charging column 3, the charging column 3 is inserted from the outside of the watch back cover 2 and passes through the FPC charging via hole pad 5, the welding end of the charging column 3 is welded from the welding groove 61 on one side of the FPC reinforcing steel sheet 6, and the welding spot is left in the welding groove 61 and is not easy to be touched by other internal components, thereby effectively improving the welding firmness, and because the welding position is on the inside, the internal elements will produce a certain extrusion effect when touching the charging end, the welding spot is extruded into the welding groove 61 together, preventing the situation of falling off, in the charging process, the charging seat 7 contacts the watch back cover 2, at the same time, the charging elastic pin 8 contacts the contact charging end of the charging column 3 and abuts against the positioning groove 31, under the action of the elastic pin spring 9, the contact of the charging elastic pin 8 and the contact charging end is more close, and the charging effect is better.

[0029] The above is only used to explain the technical scheme of the utility model and is not limited, and other modifications or equivalent replacements of the technical scheme of the utility model made by the ordinary skilled in the art should be covered in the claim range of the utility model.
