[0016] This invention also provides a wristband device assembly, including the wristband device charger and the wristband device;

[0017] When charging, the conductive spring extends into the corresponding charging port, and the charging post enters through the opening slot and engages with the second locking hole.

[0018] The beneficial effects achieved by this invention due to the adoption of the above technical solution are as follows:

[0019] The wristband device charger of the present invention includes a main body and a charging cable disposed on the main body. The main body is provided with two charging guide posts electrically connected to the charging cable and having a radial dimension of A. Each charging guide post is provided with a conductive structure. Each conductive structure includes an insulating push block and a conductive spring connected together. The conductive spring is provided with a first locking hole, a connecting groove, a second locking hole, and an opening groove sequentially along its length direction.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0033] Depend on Figures 1 to 3As shown in the figure, this embodiment discloses a wristband device charger 1, including a main body 11 and a charging cable 12 disposed on the main body 11. Two charging guide posts 13, each with a radial dimension of A, are spaced apart along the length of the main body 11 and electrically connected to the charging cable 12. Each charging guide post 13 has a conductive structure 14. Each conductive structure 14 includes an insulating push block 141 and a conductive spring piece 142 connected to each other (the insulating push block 141 and the conductive spring piece 142 are preferably an integral structure formed by insert injection molding). The conductive spring piece 142 has a radial dimension of A along its length. The structure 14 has a first locking hole 1421, a connecting groove 1422, a second locking hole 1423, and an opening groove 1424 connected sequentially along its length. The first locking hole 1421 and the second locking hole 1423 have the same diameter and are both used to fit and engage with the charging guide post 13. The width of the connecting groove 1422 and the opening groove 1424 is smaller than the diameter of the first locking hole 1421. The conductive structure 14 has at least two states: initial and charging. In the initial state, the charging guide post 13 is engaged in the second locking hole 1423. In the charging state, the charging guide post 13 is engaged in the first locking hole 1421. The main body 11 contains wires, an FPC board, or a PCB board, and the charging guide post 13 is electrically connected to the charging cable 12 via the wires, the FPC board, or the PCB board.

[0034] To prevent the conductive spring 142 from axially shifting on the charging post 13 and affecting the reliability of the charging process, this embodiment further optimizes the above structure. Two annular limiting protrusions 131 are provided on the charging post 13 at axial intervals, and the conductive spring 142 is restricted between the two annular limiting protrusions 131; that is, the thickness of the conductive spring 142 is adapted to the spacing between the two annular limiting protrusions 131.

[0035] To ensure that the charging guide post 13 can smoothly switch between the first card hole 1421 and the second card hole 1423, this embodiment has been further optimized. The two side walls of the optimized connecting groove 1422 are connected to the inner walls of the first card hole 1421 and the second card hole 1423 by a rounded transition; the two side walls of the opening groove 1424 are connected to the inner wall of the second card hole 1423 by a rounded transition.

[0036] In some embodiments, the conductive spring 142 is a sheet-like structure. In this embodiment, the outer contour of the conductive spring 142 is a figure-eight shape, which is easier to elastically deform and rebound after deformation compared to a sheet-like structure, thus increasing portability and reliability during charging connection. In this embodiment, the two conductive structures 14 are arranged opposite to each other.

[0037] Depend on Figures 4 to 6 As shown in the illustration, this embodiment also discloses a wristband device 2 and a wristband device assembly; the wristband device assembly includes... Figure 1The diagram shows a wristband charger 1 and a wristband device 2 adapted to the charger 1. The wristband device 2 includes a housing 21 and a main board 22 disposed within the housing 21. Two vertically extending charging posts 23 with a radial dimension A are embedded in the side of the housing 21. The charging posts 23 are electrically connected to the main board 22 via electrical connectors. Two horizontally extending charging ports 24, corresponding one-to-one with the charging posts 23, are provided on the outer side wall of the housing 21. The snap-fit ​​sections (middle parts) of the charging posts 23 are located within the corresponding charging ports 24. The housing 21 includes an upper shell 211 and a lower shell 212 that are fastened together. A screen 213 is provided on the lower shell 212. The two charging ports 24 and the charging posts 23 are located on opposite sides of the lower shell 212.

[0038] In this embodiment, the electrical connector includes an FPC flexible plate 25 and a conductive screw 26 embedded in the bottom of the lower housing 212. One end of the FPC flexible plate 25 abuts against the bottom of the charging post 23, and the other end is a clamping end that fits against the bottom plane of the lower housing 212. The clamping end is provided with a conductive screw 26, and the bottom end of the conductive screw 26 is connected to the bottom of the lower housing 212. The top end of the conductive screw 26 abuts against the motherboard spring 221 on the motherboard 22. The lower housing 212, the charging post 23, and the FPC flexible plate 25 are an integral structure formed by insert injection molding.

[0039] Depend on Figure 7 As shown, this embodiment also discloses a second type of wristband device charger 1, with two conductive structures 14 arranged side by side. Figure 8 As shown, with Figure 7 In the wristband device 2 adapted to the wristband device charger 1 shown, the two charging ports 24 and the two charging posts 23 are located on the same side of the lower shell 212; the structure of the electrical connector is the same as described above, only the setting position is adjusted, and will not be described in detail here.

[0040] Depend on Figure 9 As shown, this embodiment also discloses a third type of wristband device charger 1; the included angle between the two conductive structures 14 is 90 degrees; to simplify the structure, the main body 11 is adjusted to an L-shaped structure. Then, with... Figure 9 In the wristband device 2 compatible with the wristband device charger 1 shown, the two charging ports 24 and the two charging posts 23 need to be located on adjacent sides of the lower shell 212 (not shown in the figure). The structure of the electrical connectors is the same as described above, only the setting position is adjusted, and will not be described in detail here.

[0041] In addition, there are many other structures that can be obtained with slight modifications based on the above ideas without requiring any labor, which will not be listed here.

[0042] During charging, the position of the main body 11 relative to the wristband device 2 is adjusted according to the position of the charging port 24, so that the charging guide post 13 is located outside the corresponding charging port 24 and the conductive spring piece 142 is aligned with the corresponding charging port 24; then the insulating push block 141 is pushed towards the charging port 24, the conductive spring piece 142 extends into the charging port 24, and at the same time the charging guide post 13 disengages from the second locking hole 1423, enters through the connecting groove 1422 and is locked in the first locking hole 1421, the charging post 23 enters through the opening groove 1424 and is locked in the second locking hole 1423, and the charging guide post 13 and the charging post 23 establish an electrical connection with the conductive spring piece 142; the charging cable 12 in the wristband device charger 1 is connected to an external power source and begins charging. After charging is completed, pull the insulating push block 141 in the opposite direction, and the conductive spring piece 142 will disengage from the charging socket 24. At the same time, the charging guide post 13 will disengage from the first locking hole 1421, enter through the connecting groove 1422 and lock into the second locking hole 1423. The charging post 23 will slide out from the opening groove 1424, cutting off the electrical connection between the charging guide post 13 and the charging post 23.

[0043] This invention allows for charging without removing the wristband device from the wrist. The wristband device charger can be directly inserted into the side of the housing, and the charging post and charging post are electrically connected by a conductive spring to perform charging; making charging more portable.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
