The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. In the description of this invention, it should be understood that the terms “center,” “longitudinal,” “lateral,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] This utility model provides a wearable electronic device, including an electronic device body and a battery case connected to the electronic device body. The battery case includes: a battery case body comprising an axially extending shell and a circumferentially formed sheath covering the shell, the shell having a radially upward opening cavity, the sheath being made of an elastomer and having corresponding openings to expose the cavity; a removable battery housed in the cavity and supplying power to the electronic device body; and a removable cover plate, the cover plate sealingly abutting against the sheath in an annular edge region to close the cavity, and being fixedly connected to the shell in a threaded connection in a central region surrounded by the annular edge region.

[0039] It should be noted that the annular edge area of ​​the cover plate is a closed annular area. The fact that the sheath is circumferentially wrapped around the housing means that, except for the open portion and at least one end for connection, the sheath constitutes the outer skin of the entire battery box body, thereby effectively achieving the integrity, structural stability, and sealing of the battery box body.

[0040] In this document, the term "axis" refers to the central axis of the battery compartment of a wearable electronic device that houses the battery. The battery-housed portion includes a housing with a sheath and a removable cover; the central axis is the central axis of the housing. The terms "axial" or "axial direction" refer to the direction along the central axis; "radial" or "radial direction" refers to a direction generally perpendicular to the axis, pointing towards or away from the axis; "radially inward" or "radially outward" refers to a component, part, position, or orientation relatively close to the axis; and "radially outward" or "radially away from the axis" refers to a component, part, position, or orientation relatively far from the axis. The term "circumferential" refers to the direction around the axis.

[0041] The above-described design of this utility model provides a highly waterproof removable battery solution. The molded sheath is partially left open to expose a cavity for accommodating the battery, and a removable cover plate covers the open portion. The cover plate seals against the sheath at its annular edge region to close the cavity, and is threadedly connected to the housing in the central region surrounded by the annular edge region. This design maintains excellent dust and water resistance without affecting the overall appearance of the wearable electronic device and allows users to easily and quickly replace the battery.

[0042] In one or more embodiments of this utility model, the sleeve is integrally formed with an annular sealing part at the abutment of the cover plate. The annular sealing part is located above the side wall of the housing surrounding the cavity. The cover plate has an annular protrusion extending downward in the annular edge region. The sleeve has an annular groove adapted to the annular protrusion. The annular sealing part is disposed in the annular groove, abuts upward against the annular protrusion, and is interference-fitted with the annular protrusion through elastic deformation.

[0043] The annular sealing part designed as described above in this utility model can be formed in one step during the overmolding process of the cover, which greatly simplifies the manufacturing and assembly process and enables a simple and convenient sealing connection between the cover plate and the battery box body.

[0044] In one or more embodiments of this utility model, the cover plate and the housing are fixedly connected by two screws, wherein the cover plate has two axially spaced through holes in the middle region, and the housing has two receiving holes that mate with the two through holes. Each screw extends radially through one of the through holes and is screwed into one of the receiving holes. The cover plate has two snap-fit ​​parts in the middle region for forming a snap-fit ​​connection with the housing. The two snap-fit ​​parts are radially offset from each other and located axially between the two through holes of the cover plate. The battery box has a handle for applying external force to the cover plate to disconnect the snap-fit ​​connection. The handle is located at one axial end of the cover plate.

[0045] The connection and disassembly between the cover plate and the housing are simply and effectively achieved through the threaded connection, snap-fit ​​connection, and handle designed as described above, as well as their relative positions. The snap-fit ​​connection facilitates the subsequent threaded connection, while the handle facilitates the application of external force to disconnect the snap-fit ​​connection and thus disassemble the cover plate.

[0046] Figure 1 The illustration shows an open-back neckband headphone 100, also known as an OWS neckband headphone. Figure 2 Schematic illustration Figure 1The wearing method of the earphone 100 is shown. The neckband earphone 100 includes a first earphone body 102, a battery case 200, a neckband 104, a control box 106, and a second earphone body 108 connected in sequence. The control box 106 contains a control motherboard. The battery case 200 supplies power to the control box 106, and the control box 106 is configured to supply power to the first earphone body 102 and the second earphone body 108.

[0047] Figure 3 Schematic illustration Figure 1 An overall view of the battery case 200 in the headphones. The battery case 200 includes a portion 200a for housing a battery 220 and an ear hook portion 200b for hanging on the ear, wherein the portion 200a for housing the battery 220 has a generally cylindrical shape, and the direction of the central axis of this portion is set as axial x. One end of the battery case 200 (in Figure 3 The left end (in the figure) is connected to the neckband 104, and the other end (in the figure, the right end) is connected to the first earphone body 102.

[0048] As shown in the figure, the battery box 200 includes a removable cover 210 and a battery box body 230. A handle 266 for removing the cover 210 and a screw 206 for securing it are also visible (see figure). Figure 4 Two soft rubber caps 204 are provided. The direction of the connecting line of the two screws 206 is consistent with the axial direction x. Within the scope of this utility model, the direction of the connecting line of the two screws 206 can also be set to deviate from the axial direction x. In this embodiment, the cover plate 210 has a longitudinally elongated shape, and its axial length is greater than its radial length.

[0049] Figure 4 An exploded view of the battery case 200 is schematically shown, illustrating that the battery case 200 includes a battery case body 230, a removable battery 220, and a removable cover 210. The battery case body 230 has a cavity 240a that opens radially upward. The removable battery 220 is housed in the cavity 240a and powers the earphone body. The cover 210 is configured to abut against the battery case body 230 in an annular edge region to close the cavity 240a and is secured to the battery case body 230 in a central region surrounded by the annular edge region by two screws 206. Further technical details will be explained in more detail below.

[0050] In this embodiment, the upper side of the screw 206 is covered by two soft rubber covers 204 to ensure the overall appearance. These two soft rubber covers 204 can be removed with a tool with a pointed tip to expose the screw 206. The soft rubber covers 204 are typically made of silicone. The cover plate 210 has two axially staggered through holes 210a in the middle region. The bottom of the battery box body 230 has two connecting posts 242, each extending radially and having a corresponding receiving hole 242a (see...). Figure 5 The screws 206 extend through the corresponding through holes 210a and are screwed into the corresponding receiving holes 242 to achieve a threaded connection. This arrangement allows for a simple and effective fixed connection between the cover plate 210 and the housing.

[0051] In one or more embodiments of this utility model, screw 206 is a self-tapping screw. In one or more embodiments of this utility model, the number of screws may be only one or more than two screws.

[0052] Figure 5 and Figure 6 Each schematically shows Figure 4 The battery box body 230 is shown in both an overall view and an exploded view. (Combined) Figure 5 and Figure 6 It is known that the battery box body 230 includes: a housing 240; a connecting section 232 for realizing the mechanical connection and electrical connection between the housing 240 and the first earphone body 102; and a sheath 260, which is radially wrapped and formed on the outside of the housing 240 and the connecting section 232. Figure 6 The exploded view shows the housing 240, the sheath 260, and the connecting section 232 separately.

[0053] Depend on Figure 6 It is understood that the connecting segment 232 includes a wire bundle 232a and two plastic parts formed at both ends of the wire bundle through a first overmolding process, namely a first plastic part 232b and a second plastic part 232c. The first plastic part 232b is configured to be inserted into the housing 240 from one side to achieve an assembled state between the housing 240 and the connecting segment 232. In this assembled state, the sheath 260 is formed on the outer side of the housing 240 and the connecting segment 232 in a subsequent second overmolding process, thereby forming the battery box body 230. The wire bundle 232a includes, for example, a shape memory alloy wire, three battery connecting wires, and two audio wires.

[0054] In addition Figure 6It is understood that the housing 240 has a cavity 240a that opens radially upward, and the sheath 260 has a corresponding opening 260a to expose the cavity 240a. The sheath 260 is made of an elastomer, such as silicone. Except for the opening 260a and the two ends for connection, the sheath 260 constitutes the outer skin of the entire battery box body 230, thereby effectively ensuring the overall appearance, structural stability, and sealing of the battery box body 230.

[0055] In this embodiment, the connecting segment 232, after being covered by a sheath 260, forms an ear hook portion 200b for hanging on the user's ear. Alternatively, in an implementation of a clip-on earphone, the connecting segment may not hang on the user's ear but rather be located on one side of the ear; therefore, the connecting segment forms an ear hook portion after being covered by a sheath.

[0056] Figure 7 and Figure 8 The diagrams illustrate the following: along Figure 3 The cross-sectional view obtained by cutting the battery box 200 along the AA and BB lines. Figure 9 A perspective view of the cover 210 facing the lower side of the battery box body 230 is shown schematically.

[0057] Combination Figures 7 to 9 The connection between the cover plate 210 and the battery box body 230 is as follows: the cover plate 210 abuts against the sleeve 260 in a sealing manner in the annular edge area to close the cavity for accommodating the battery 220; on the other hand, the cover plate 210 is fixedly connected to the housing 240 in the middle area surrounded by the annular edge area by a threaded connection.

[0058] Depend on Figure 7As can be seen, in this embodiment, at the contact point between the sleeve 260 and the cover plate 210, the cover plate 210 is provided with a downwardly extending annular protrusion 214, and the sleeve 260 is provided with an annular groove 262 adapted to the annular protrusion 214. In this embodiment, the sleeve 260 also integrally forms an annular sealing portion 264 within the annular groove 262. That is, the annular sealing portion 264 is formed simultaneously during the overmolding process of the sleeve 260. The annular sealing portion 264 has an upwardly protruding profile, thereby being able to abut upward against the downwardly extending annular protrusion 214 and to be in an interference fit with the annular protrusion 214 through elastic deformation. The annular sealing portion 264 is located above the side wall of the housing 240 surrounding the cavity 240a, that is, the side wall of the housing 240 surrounding the cavity 240a forms a support below the annular sealing portion 264 to achieve a seal. The above design method can easily and conveniently achieve a sealed connection between the cover plate and the battery box body. Because the annular sealing part 264, as the built-in sealing ring of the sleeve 160, can be formed in one step during the sleeve covering molding process, the manufacturing and assembly process is greatly simplified, and a high level of waterproof and dustproof performance is achieved.

[0059] In one or more embodiments of this utility model, the seal between the cover plate and the sleeve can be conceived to be achieved not by an integrally formed annular sealing part, but by a separate sealing ring.

[0060] in addition, Figure 8 The sectional view corresponds to Figure 3 The BB section line passes through both screws 206. The line connecting these two screws 206 (the BB section line) essentially corresponds to the axial x-axis of the battery box 200 (see [reference]). Figure 3 and Figure 6 ).from Figure 8 As can be seen, the cover plate 210 and the housing 240 are detachably fixedly connected by two screws 206. Sealing rings 208 are respectively provided at the through holes 210a of the two screws 206 between the cover plate 210 and the housing 240. This ensures a reliable seal of the cover plate 210 in the area where it is fixedly connected to the housing 240. According to this embodiment, the sealing performance of the removable battery solution in the battery box 200 is achieved by the annular sealing part 264 provided on the casing 260 and the two sealing rings 208 together.

[0061] Battery 220 is configured as a cylindrical battery, with its axis aligned with the x-axis of battery case 200. Battery 220 is positioned axially between two connecting posts 242. This design ensures reliable fixation of the cover while allowing for larger capacity battery designs.

[0062] Combination Figure 4 , Figure 7 and Figure 9As can be seen, the cover plate 210 has two latching portions 212 in the middle region. The two latching portions are radially offset from each other and axially located between the two through holes 210a of the cover plate 210. Each latching portion 212 extends downward and has a latching groove 212a. The housing 240 has two radially inwardly extending radial protrusions 244 ( Figure 10 (As shown more clearly), the radial protrusion 244 has a bevel 244a so that the latching part 212 elastically deforms during insertion. Thus, the latching part 212 can be inserted into the housing 240 during the installation of the cover plate 210, and the radial protrusion 244 engages with the latching groove 212a through elastic deformation during insertion to form a latching connection. The dimensions of the radial protrusion 244 are designed to both achieve the latching connection and allow the latching part 212 to separate from the radial protrusion 244 under external force.

[0063] Figure 10 Another view of the battery box body is shown. This view shows two latching portions 244, two connecting posts 242 for receiving screws 206, and their relative positions. Corresponding to the positions of the two latching portions 212, two radial protrusions 244 are respectively provided on opposite sidewall sections of the housing 240, but in this embodiment they are not exactly opposite each other radially. Therefore, in Figure 7 Only the cross-sectional view shown shows Figure 10 The radial protrusion 244 is located on the right side.

[0064] In one or more embodiments of this utility model, the cover plate 210 may also be connected to the housing 240 by snap-fit ​​in other design ways.

[0065] Figures 3 to 6 As can be seen from the image, the battery case 200 is provided with a handle 266 for removing the cover 210. The handle 266 is located at the axial end of the cover 210 away from the first earphone body 102, that is, at the axial end of the cover 210 near the neckband 104, and is used to apply external force to the cover 210 to disconnect the snap-fit ​​connection. In one or more embodiments of this utility model, the handle 266 may also be located on the axial end of the cover 210 near the first earphone body 102.

[0066] Figure 11 Additionally, it shows along Figure 3 The cross-sectional view obtained by cutting along the CC line clearly shows the handle portion 266. As can be seen from the figure, the handle portion 266 includes an upwardly opening recess 268 constructed on the sheath 260 and a corresponding recess 218 constructed below the edge of the cover plate 210, the recess 268 communicating with the corresponding recess 218. The corresponding recess 218 is further... Figure 12Sub-image d is more clearly visible. Users can use tools or their hands to insert the handle 266 and hook the edge of the cover 210 to lift the cover 210.

[0067] In addition Figure 4 and Figure 5 As can be seen, the battery 220 has a plug 222, and the housing 240 has a connector, which includes an adapter plate 250 fixed to the housing 240 and a socket 252 for receiving the plug 222 to form an electrical connection. The adapter plate 250 is fixed to the housing 240, for example, by a heat-fused post. A layer of foam 254 can be placed over the adapter plate 250 to cover it. In addition, a layer of foam 256 is provided below the battery 220 to cover the wiring underneath.

[0068] Figure 12 The disassembly process of the battery case 200 is shown, including sub-figure ae representing multiple steps. First, the battery case 200 is provided (sub-figure a); the soft rubber covers 204 on both sides are removed to expose screws 206 (sub-figure b); screws 206 are unscrewed using a screwdriver (sub-figure c); cover plate 210 is removed using the handle 266 (sub-figure d); battery 220 is removed, plug 222 attached to socket 252 is manually disconnected, and a new battery is replaced (sub-figure e). Then, the entire battery case 200 is reassembled by reversing the steps in the order of sub-figure ae.

[0069] This embodiment uses an open-back neckband earphone 100 as an example of a wearable electronic device. However, the wearable electronic device according to this invention is not limited to this, but can include various wireless earphones, such as various TWS and OWS earphones, as well as other types of wearable electronic devices, such as smart glasses. The open-back neckband earphone 100 shown here has an ear-hook design and includes a neckband to connect the two earphone bodies together.
