Description

Technical Field

[0001] This utility model relates to the technical field of smartwatch protective products, and specifically to a smartwatch protective case and a smartwatch charging structure using the protective case. Background Technology

[0002] With the increasing popularity of smartwatches, adding protective cases has become a common practice for users to protect their devices and express their individuality. Existing smartwatch protective cases, such as the technical solution disclosed in Chinese patent CN216748457U, typically include a bezel and a protective sleeve, which structurally enclose the watch face to provide protection against drops and scratches.

[0003] However, these protective cases have a significant drawback: they are primarily designed for models where the charging electrodes are located on the back of the watch (usually charged via a magnetic clasp). Because the case doesn't cover the back of the watch, charging a smartwatch doesn't require separating the case from the watch; the watch can be charged directly via the charger. However, for smartwatches with charging electrodes on the side, the thickness of the case prevents direct contact between the charging electrodes on the watch's side and the charger's electrodes, forcing users to remove the case every time they charge, which is extremely inconvenient. Creating a large opening on the side of the case to solve this problem would weaken the protective performance of that area and affect the aesthetics.

[0004] Furthermore, for smartwatches with a round body and curved sides, the presence of a protective case makes it more difficult for the charging adapter's electrodes to make stable contact with the electrodes on the watch's curved surface, exacerbating the aforementioned problem.

[0005] Therefore, there is an urgent need for a protective case solution that can provide comprehensive protection without affecting the normal charging of side-electrode smartwatches. In view of this, the inventors propose the following technical solution. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a smart watch protective case and a smart watch charging structure using the protective case.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a smart watch protective case, suitable for smart watches with charging electrodes located on the side, the protective case includes a frame-shaped shell, an electrode hole corresponding to the position of the charging electrode on the smart watch is opened on the side of the shell, and a conductive post is fixed in the electrode hole; after the shell is fitted onto the smart watch, the charging electrode on the smart watch forms a conductive contact with the conductive post.

[0008] Furthermore, in the above technical solution, the shell integrally formed by plastic material includes an annular upper shell and a left shell and a right shell formed on the left and right sides below the upper shell. The electrode hole is opened on the left shell or the right shell. After the shell is fitted onto the smartwatch, the upper shell, the left shell, and the right shell form an upper and lower clamp to fix the smartwatch.

[0009] Furthermore, in the above technical solution, the protective shell also includes a transparent plate, and an annular flange is formed on the inner side of the upper opening of the upper shell. The transparent plate is fixed to the upper opening of the upper shell through the annular flange.

[0010] Furthermore, in the above technical solution, a sealing groove is formed on the outer side of the annular flange.

[0011] Furthermore, in the above technical solution, a clearance space is formed between the left and right shells for the smartwatch strap to pass through.

[0012] Furthermore, in the above technical solution, the right shell is composed of two spaced-apart first shells and second shells.

[0013] Furthermore, in the above technical solution, at least two electrode holes corresponding to the charging electrode positions on the smartwatch are provided on the left shell, and the right shell is composed of two spaced-apart first shells and second shells. The first shell is provided with an adjustment hole, and the second shell is provided with an adjustment button.

[0014] Furthermore, in the above technical solution, the main body of the shell is circular, the inner end face of the conductive post is recessed into the inner wall of the left or right shell, and the outer end face of the conductive post protrudes from the outer wall of the left or right shell.

[0015] Furthermore, in the above technical solution, the conductive column has a tapered shape that is larger on the inside and smaller on the outside.

[0016] The left shell has two electrode holes. The axis of the conductive post in each electrode hole does not coincide with the diameter of the shell, and its axis is deflected towards the center line between the two electrode holes.

[0017] This utility model also provides a charging structure for a smartwatch, comprising: a smartwatch with charging electrodes on its side, a protective case sandwiched on the smartwatch, and a charger adapted to the smartwatch. The charger has a receiving groove adapted to the side of the smartwatch, and a conductive electrode is disposed in the receiving groove. The protective case is one of the aforementioned smartwatch protective cases. The charging electrodes on the smartwatch form a conductive contact with the conductive electrodes in the receiving groove through conductive posts.

[0018] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: 1. Enables charging without disassembly: By integrating conductive pillars into the side wall of the protective case, a conductive bridge is built from the charger to the watch electrodes, allowing users to charge the watch directly without removing the protective case, greatly improving the convenience of use.

[0019] 2. Maintain comprehensive protection: Compared with the compromise solution of making large gaps, this utility model only makes small holes to install conductive posts, thus maintaining the structural integrity and protective performance of the protective shell to the greatest extent.

[0020] 3. High versatility: This utility model specifically solves the problem of charging watches with round or side electrodes, thus expanding the range of applicable models for the protective case.

[0021] 4. Simple and reliable structure: This utility model only adds conductive post components to the existing mature protective shell structure, which is simple in structure, easy to manufacture, and has stable and reliable electrical connection. Attached Figure Description

Detailed Implementation

[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] This utility model provides a smartwatch protective case, which is used to adapt to smartwatches with charging electrodes located on the side, so that charging can be performed directly without separating the protective case from the watch.

[0025] See Figures 1 to 4 As shown, the protective shell in this utility model includes: a shell 10 and a transparent plate 20.

[0026] The housing 10 is integrally molded from plastic material, and its main body is a circular frame shape. The housing 10 includes: an annular upper housing 1 and a left housing 2 and a right housing 3 formed on the left and right sides below the upper housing 1.

[0027] An annular flange 11 is formed on the inner side of the upper opening of the upper housing 1. The transparent plate 20 is adapted to the upper opening of the upper housing 1 and is positioned by the annular flange 11, and is fixed to the upper opening of the upper housing 1 by adhesive. To ensure a seal, a sealing groove 12 is formed on the outer side of the annular flange 11. The sealing groove 12 can be used to fill with sealing adhesive.

[0028] Combination Figure 4 As shown, the sidewall of the housing 10 is generally drum-shaped with the middle protruding outwards. When the housing 10 is fitted onto the smartwatch 6, the upper housing 1, the left housing 2, and the right housing 3 form an upper and lower clamp to fix the smartwatch 6, and the smartwatch 6 is protected by the housing 10.

[0029] Combination Figure 5 As shown, the smartwatch protective case provided by this utility model is particularly suitable for a smartwatch 6 with a circular main body. The smartwatch 6 has a circular main body with two charging electrodes 61 on one of its arc-shaped sides and strap mounting positions 62 on opposite sides. Correspondingly, the housing 10 has a circular main body and two electrode holes 21 on the left housing 2 corresponding to the charging electrodes 61 on the smartwatch 6. A conductive post 4 is fixed in the electrode holes 21. When the housing 10 is fitted onto the smartwatch 6, the charging electrodes 61 on the smartwatch 6 form conductive contact with the conductive post 4. In addition, a clearance position 5 is formed between the left housing 2 and the right housing 3 for the smartwatch strap to pass through.

[0030] Regarding the placement of buttons, knobs, and other control devices in the smartwatch 6, the right housing 3 is composed of two spaced-apart first housings 31 and second housings 32. The first housing 31 has an adjustment hole, and the second housing 32 has an adjustment button 320 formed by a hollow design.

[0031] like Figure 4 As shown, the inner end face of the conductive post 4 is recessed into the inner wall of the left housing 2, and the outer end face of the conductive post 4 protrudes from the outer wall of the left housing 2. Since the charging electrode 61 on the smartwatch 6 typically protrudes slightly from the side of the watch, the inner end face of the conductive post 4 is recessed into the inner wall of the left housing 2 to provide accommodating space for the charging electrode 61. Simultaneously, when the protective case is fitted onto the smartwatch 6, the conductive post 4 will replace the charging electrode 61 in connecting to the external charger; therefore, the outer end face of the conductive post 4 protrudes from the outer wall of the left housing 2 to facilitate connection with the external charger.

[0032] In addition, in order to prevent the conductive post 4 from being pushed out by the charging electrode 61 from the inside out, the conductive post 4 is tapered with a larger inner diameter and a smaller outer diameter.

[0033] Combination Figure 6As shown, this invention requires compatibility with a specific charger 7 during charging. The charger 7 has a receiving groove 71 that adapts to the side of the smartwatch 6, and a conductive electrode 70 is disposed within the receiving groove 71. During charging, the smartwatch 6, with its protective case attached, can be directly placed in the receiving groove 71. The current path is: conductive electrode 70 -> outer end face of conductive post 4 -> body of conductive post 4 -> inner end face of conductive post 4 -> charging electrode 61. That is, the conductive electrode 70 of the charger 7 is connected to the charging electrode 61 of the smartwatch through the conductive post 4, thus perfectly solving the problem of the protective case isolating the charging path.

[0034] Combination Figure 5 As shown, since both the smartwatch 6 and the casing 10 are circular, if the conductive posts 4 extend directly along the radial direction during installation, the distance between the inner sides of the two conductive posts 4 will be smaller than the distance between their outer sides, potentially causing misalignment between the conductive posts 4 and the conductive electrodes 70 on the charger 7. Therefore, the conductive posts 4 in this invention employ a deflection design, meaning that the axis of the conductive post 4 located in each electrode hole 21 does not coincide with the radial line of the casing 10, but is deflected towards the center line of the two electrode holes 21. This ensures that the distance between the inner and outer sides of the two conductive posts 4 matches, thus achieving precise alignment with the conductive electrodes 70 on the charger 7.

[0035] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model.
