Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] The charger of the preferred embodiment of this utility model, such as Figure 1 As shown, see also Figures 2-7 It includes a power-gathering head 1 and a wireless charging module 2. The circuit board 10 of the power-gathering head 1 is connected to the wireless charging module 2 via a wire (not shown in the figure), wherein: The power take-off head 1 and the wireless charging module 2 are provided with a rotating shaft 3 on one side and two sleeves 4 that are respectively rotatably sleeved on both ends of the rotating shaft 3 on the other side. A first positioning groove 30 and a second positioning groove 31 are provided on the end faces of both ends of the rotating shaft 3. The first positioning groove 30 and the second positioning groove 31 intersect each other and the intersection point is located on the axis of the rotating shaft 3. The sleeve 4 is axially movable and has a positioning shaft 40 and an elastic reset member 41 for resetting the positioning shaft 40. The end of the positioning shaft 40 is provided with a first positioning protrusion 400. By switching between the first positioning protrusion 400 and the first positioning groove 30 and the second positioning groove 31, the wireless charging module 2 can achieve a first position (e.g., Figure 1 (as shown in the state) and second position (as shown in the state) Figure 2 Position switching (as shown in the image); Using the charger structure of this application, during use, the wireless charging module 2 can be rotated and adjusted relative to the power-taking head 1 through the cooperation of the two sleeves 4 and the rotating shaft 3, completing the position switching between the first position and the second position (e.g., Figure 1 The storage status shown and Figure 2 The position switching between the unfolded states is shown; of course, other form switching can also be set according to actual needs. During the position switching process, the first positioning protrusion 400 squeezes the positioning shaft 40. As the positioning shaft 40 retracts, the elastic reset member 41 is compressed. Before and after the position switching, the position is positioned by the cooperation between the first positioning protrusion 400 and the first positioning groove 30, and the cooperation between the first positioning protrusion 400 and the second positioning groove 31, respectively. The elastic force of the elastic reset member 41 locks the position. This effectively solves the multi-state charging problem of devices such as smartwatches and has excellent reliability. The position switching structure is reasonable and compact, with small size and low cost. It should be noted that the rotating shaft 3 of this application can be composed of two rotating columns as described below, or it can be a single piece. The setting position can also be varied and is not limited. The solution obtained based on the single rotating shaft 3 or the change of setting position also falls within the protection scope of this application.

[0018] In an optional embodiment, the elastic reset member 41 is a torsion spring, which is disposed inside the sleeve 4, with one end fixed or abutting against the one-end positioning shaft 40, and the other end fixed or abutting against the sleeve 4.

[0023] In an optional embodiment, the middle plate 13 is provided with two first clamping grooves 130, and the upper cover 12 is provided with two second clamping grooves 121; the first clamping grooves 130 and the second clamping grooves 121 cooperate to clamp and fix the sleeve 4. When assembling the sleeve 4, first assemble the middle plate 13 with the bottom shell 11, and then install the top cover 12 with the bottom shell 11. The sleeve 4 is clamped and fixed by the cooperation of the first clamping groove 130 and the second clamping groove 121.

[0024] Furthermore, in order to ensure the reliability of the sleeve 4 clamping assembly, two second positioning protrusions 43 and two third positioning planes 44 can be provided on the outer surface of the sleeve 4. The middle plate 13 is provided with two fourth positioning grooves 131 that correspond one-to-one with the second positioning protrusions 43 and two fourth positioning planes 132 that correspond one-to-one with the third positioning planes 44; The upper cover 12 is provided with two fifth positioning grooves 122 that correspond one-to-one with the second positioning protrusions 43 and two fifth positioning planes 123 that correspond one-to-one with the third positioning planes 44; This alignment design ensures the stability of the sleeve 4 position and prevents it from becoming loose.

[0025] In an optional embodiment, the rotating shaft 3 is composed of two coaxial rotating columns 32, and the rotating columns 32 are provided with an annular positioning groove 320; the upper cover 12 is provided with a third positioning groove 124 corresponding to the annular positioning groove 320; during assembly, the two third positioning grooves 124 are inserted into the annular positioning groove 320 to complete the positioning of the rotating shaft 3 and ensure the stability of the rotating shaft 3.
