References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0054] Referring to Figures 1 to 3, an embodiment of the present application provides a wearable device, such as headphones, glasses, watches, bracelets, etc.; the wearable device includes a housing assembly 100, an interface assembly 200, a circuit board 300, a wire assembly 400, and other functional components that exist as needed (such as a microphone assembly, a speaker assembly, a button assembly, a voice coil assembly, a battery assembly, etc. that implement functions related to non-in-ear Bluetooth headphones); the details are described below.

[0055] The shell assembly 100 is mainly used as an installation carrier for the interface assembly 200, the circuit board 300 and other functional components. It can be understood that the shell assembly 100 is a collection of related components that constitute the overall outline of the wearable device. With the help of the shell assembly 100, the wearable device can be moved, carried, worn, operated and used.

[0056] The circuit board 300 is located within the housing assembly 100. It can be understood as the wearable device's main control board or motherboard, regulating and managing all or some of the functional components within the wearable device. For example, if the wearable device is a headset, the circuit board 300 can be used to convert and process electrical signals within the headset to support various headset functions (e.g., turning the headset on and off, switching playback content, and increasing or decreasing the volume).

[0057] The interface component 200 is arranged on the shell component 100, for example, the interface component 200 is arranged inside the shell component 100 in a manner that its interface end can be exposed from the shell component 100; the interface component 200 can be used to connect to an external power source to charge the wearable device; the interface component 200 can also be used to connect to an external device (such as a mobile phone, a computer, etc.) to transmit data between the external device and the wearable device; illustratively, the interface component 200 can be a Type-C interface, a USB interface, a magnetic interface, a Lighting interface, etc., and the specific selection is made according to actual needs and is not limited here.

[0058] In one embodiment, referring to Figures 1 and 2, the housing assembly 100 includes a first housing 110, and the first housing 110 is provided with a connected accommodating cavity 111 and an accommodating groove 112; wherein, the circuit board 300 is arranged in the accommodating cavity 111, the interface assembly 200 is inserted into the accommodating groove 112, and the wire assembly 400 is electrically connected between the circuit board 300 and the interface assembly 200.

[0059] Illustratively, the wire assembly 400 may be a wire, a flat cable, a flexible printed circuit (FPC), etc., and the selection is made according to actual needs and is not limited here.

[0060] It should be noted that the bold solid line in Figure 1 represents the wire assembly 400, which is only for the purpose of reflecting the electrical connection relationship between the circuit board 300, the interface assembly 200 and the wire assembly 400, and does not represent the specific structure and layout of the wire assembly 400, nor does it represent the structural structure of the connection between the wire assembly 400 and the circuit board 300 and the interface assembly 200.

[0061] First, compared with the solution in the related art in which the interface component 200 is directly welded to the circuit board 300, by separately arranging the interface component 200 and the circuit board 300 in the shell component 100 and using the wire component 400 to electrically connect the circuit board 300 and the interface component 200, it can effectively improve the installation position and installation posture freedom of the interface component 200 and the circuit board 300, and reduce the specific size, shape and other requirements of the interface component 200 and the circuit board 300 for the assembly space. Therefore, according to the overall structural architecture of the wearable device, the position and shape of the circuit board 300 and the accommodating cavity 111, the interface component 200 and the accommodating groove 112 can be flexibly adjusted and set, creating favorable conditions for reducing the assembly difficulty of the wearable device.

[0062] Secondly, with the help of the electrical connection relationship established between the circuit board 300 and the interface component 200 by the wire component 400, the circuit board 300 and the interface component 200 can be respectively arranged in the accommodating cavity 111 and the accommodating groove 112 in the form of maintaining a certain distance between each other, which can effectively reduce the encroachment of the interface component 200 on the accommodating cavity 111 or the assembly space of the circuit board 300, and reduce the possibility of the interface component 200 interfering with the circuit board 300, thereby helping to improve the effectiveness and stability of the operation of the interface component 200 and the circuit board 300, and improve the reliability and service life of the wearable device.

[0063] Third, by separately arranging the interface component 200 and the circuit board 300 in different assembly spaces (i.e., the accommodating groove 112 and the accommodating cavity 111), cavity openings corresponding to the interface component 200 and the circuit board 300 can be set on the shell component 100, respectively, which is conducive to reducing the opening size of the shell component 100 and saving assembly space, thereby creating conditions for enhancing the structural compactness of the wearable device and realizing the miniaturization design of the wearable device; and the smaller opening size can also effectively ensure the structural strength of the cavity and even the shell component 100; and it is convenient to install the interface component 200 and the circuit board 300 separately (for example, an outside-to-inside assembly method can be adopted to conveniently and quickly insert the interface component 200 into the accommodating groove 112), thereby effectively reducing the difficulty of assembling the interface component 200, the circuit board 300, and even the wearable device as a whole.

[0064] In one embodiment, please refer to Figure 2 in combination with Figure 1, the shell assembly 100 (specifically, the first shell 110) has a first side wall 120 and a second side wall 130 that are connected at an angle; wherein the length of the first side wall 120 is greater than the length of the second side wall 130. It can also be understood that the length direction of the first side wall 120 is the length direction of the wearable device or the first shell 110, and the length direction of the second side wall 130 can be the same direction as the width direction of the wearable device or the first shell 110 (that is, the first side wall 120 and the second side wall 130 are connected at approximately a right angle), and the length direction of the second side wall 130 can also be a direction with a certain deflection angle relative to the width direction of the wearable device (or the first shell 110) (that is, the first side wall 120 and the second side wall 130 are connected at approximately an acute angle or an obtuse angle).

[0065] For example, if the wearable device is a non-in-ear Bluetooth headset, the first sidewall 120 and the second sidewall 130 can be the two sidewalls of the housing assembly 100 that are away from the ear hook portion of the headset and are connected to each other. The receiving groove 112 is provided on the second sidewall 130, that is, the interface assembly 200 is provided in the width direction of the housing assembly 100 or the wearable device.

[0066] Similarly, taking the wearable device as a non-in-ear Bluetooth headset as an example, in the relevant technology, the interface component 200 and other functional components (such as the button component) are usually arranged along the length direction of the headset. This will obviously increase the requirements for the length dimension of the headset (such as increasing the length of the relevant cavity structure in the shell component 100,) the length dimension of the first side wall 120), and is not conducive to the miniaturization design of the headset.

[0067] In this embodiment, by adjusting the interface component 200 to be set in the width direction of the wearable device, the size requirements of the shell component 100 or the cavity structure within the shell component 100 in the overall length direction of the wearable device can be effectively reduced, so that a smaller cavity structure (such as the accommodating groove 112) can be set in the shell component 100, thereby realizing the assembly of functional components such as the interface component 200 and the circuit board 300, thereby facilitating the miniaturization and compact design of the wearable device.

[0068] In some embodiments, referring to FIG. 2 , the angle between the first side wall 120 and the second side wall 130 is an obtuse angle, which can reduce the size of the wearable device in its width direction, so that the accommodating groove 112 (together with the interface assembly 200 ) presents a structural form that is tilted relative to the first side wall 120 , which is beneficial to enhancing the structural compactness of the wearable device.

[0069] Of course, according to the overall contour shape and structural setting requirements of the wearable device, the angle between the first side wall 120 and the second side wall 130 can also be set to a right angle, an acute angle, etc., which is not limited here.

[0070] It should be noted that the use of bold dashed lines in FIG2 to indicate the first side wall 120 and the second side wall 130 is merely to illustrate the approximate position and orientation of the first side wall 120 and the second side wall 130 within the housing assembly 100, and does not represent the structural form and dimensions of the first side wall 120 and the second side wall 130. Furthermore, the bold solid lines with double arrows in FIG2 illustrate the overall length and width of the wearable device.

[0071] In other embodiments, please refer to Figure 3. Based on the implementation principle of separately setting the interface component 200 and the circuit board 300, the receiving groove 112 (together with the interface component 200) can also be set on the first side wall 120 to meet different design requirements; it will not be repeated here.

[0072] The following mainly introduces the interface component 200 and the structure related to the interface component 200. For other parts of the wearable device, reference can be made to the existing technology.

[0073] In one embodiment, referring to Figures 1 to 11 , the interface assembly 200 includes a main body 210 and a flange 220 . The main body 210 is inserted into the receiving slot 112 and primarily serves as a carrier for connecting the interface assembly 200 to an external plug (e.g., a power plug for an external power source, a data plug for an external device, etc.). The flange 220 is disposed on a side of the main body 210 that is distal to the receiving cavity 111 . Accordingly, the housing assembly 100 (specifically, the first housing 110 ) further includes a support surface 140 , which is located outside the receiving slot 112 on a side distal to the receiving cavity 111 , and the flange 220 is supported in contact with the support surface 140 .

[0074] On the one hand, by utilizing the matching relationship between the flange portion 220 and the support table 140, the interface component 200 can be positioned and restricted within the receiving groove 112 by only providing an opening suitable for the insertion of the main body portion 210 in the receiving groove 112. This not only helps to reduce the opening size of the receiving groove 112, but also helps to save the assembly space of the interface component 200.

[0075] On the other hand, please refer to Figure 3. Based on the structural form of the support table 140 supporting the support flange portion 220, the interface component 200 can be quickly assembled to the shell component 100 from the outside to the inside (i.e., from the outside of the shell component 100 toward its inside), thereby effectively reducing the difficulty of assembling the interface component 200.

[0076] It should be noted that the support table 140 is schematically illustrated in a dotted frame in FIG11 , which is only for indicating the relative positional relationship between the support table 140 and the flange portion 220 , and does not indicate the structural form and size of the support table 140 .

[0077] Further, referring to Figure 11, a sealant 500 is provided between the flange portion 220 and the support table 140. With the help of the sealant 500, the flange portion 220 can be firmly fixed to the support table 140, thereby firmly assembling the interface component 200 in the receiving groove 112, thereby increasing the stability of the connection between the interface component 200 and the shell component 100; at the same time, the structural gap between the interface component 200 and the shell component 100 can also be filled at the support table 140 to improve the sealing performance.

[0078] In some embodiments, a glue groove (not shown) is provided on the support table 140, and the flange portion 220 covers the glue groove, and at least a portion of the sealant 500 is accommodated in the glue groove. Using the glue groove to accommodate the sealant 500 not only further enhances the stability and sealing of the connection between the interface assembly 200 and the housing assembly 100, but also reduces the height difference between the interface assembly 200 and the housing assembly 100 in the insertion direction of the interface assembly 200, thereby making the structure of the wearable device more compact and facilitating the miniaturization design of the wearable device.

[0079] Of course, a glue containing groove may be provided on the flange portion 220 , or a glue containing groove may be provided on both the flange portion 220 and the support table 140 ; ​​details will not be given here.

[0080] It should be noted that the "insertion direction of the interface component 200" (hereinafter referred to as the "insertion direction") is defined in this document, mainly to illustrate the structural matching relationship between related components. The insertion direction can be understood as the direction in which the interface component 200 and the external plug are plugged into and fitted with each other, and can also be understood as the direction in which the interface component 200 is plugged into and pulled out of the accommodating slot 112 during the disassembly and assembly process (for example, the bold dotted line with double arrows in Figure 3 represents the insertion direction).

[0081] In some other embodiments, please refer to Figure 2 and combined with Figure 11, the shell assembly 100 also includes a second shell 150 connected to the first shell 110, and the second shell 150 is configured to press and block the flange portion 220 from the side of the flange portion 220 away from the support table 140; a sealant 500 (or together with a sealant groove) is provided between the second shell 150 and the flange portion 220.

[0082] Therefore, by pressing and clamping the flange portion 220 between the support table 140 and the second shell 150, the position of the interface component 200 in the accommodating groove 112 or the shell component 100 can be effectively limited, reducing the possibility of shaking or position displacement of the interface component 200, and improving the stability and reliability of the installation of the interface component 200.

[0083] At the same time, the flange portion 220 is shielded by the second shell 150 so that the flange portion 220 is not exposed to the outside of the shell assembly 100, so that the user cannot see the flange portion 220 from the outside of the wearable device, which is beneficial to improving the appearance of the wearable device.

[0084] Furthermore, the flange portion 220 may adopt different shapes to adapt to the overall structural form of the interface assembly 200 or meet different assembly requirements.

[0085] For example, referring to Figures 7 and 8 , the flange portion 220 has an annular structure (e.g., a regular annular structure or a special-shaped annular structure), that is, the flange portion 220 is disposed around the edge of the main body 210 away from the accommodating cavity 111. Accordingly, the support table 140 can have an annular table structure disposed around the edge of the accommodating groove 112 away from the accommodating cavity 111 (i.e., the notch of the accommodating groove 112 away from the accommodating cavity 111).

[0086] As a result, the contact area between the support table 140 and the flange portion 220 can be effectively increased, and the support table 140 can provide uniform and reliable support to the interface assembly 200. As for the glue holding groove, the glue holding groove can be set on the support table 140 around the notch on the side of the receiving groove 112 away from the receiving cavity 111. In this way, when the interface assembly 200 is installed, glue can be completely dispensed around the receiving groove 112 to form a sealant 500, effectively improving the sealing performance.

[0087] For example, referring to FIG9 , the number of flange portions 220 is set to be multiple (e.g., two, three, or other larger numbers), and the multiple flange portions 220 are spaced apart around the edge of the main body 210 on the side away from the accommodating cavity 111. Accordingly, the support table 140 can be an annular table structure disposed around the edge of the accommodating groove 112 on the side away from the accommodating cavity 111, or can be a plurality of support structures spaced apart around the notches of the accommodating groove 112 on the side away from the accommodating cavity 111.

[0088] Thus, based on the number and arrangement of the flange portions 220, a multi-point fixed connection between the interface assembly 200 and the shell assembly 100 can be achieved; it can be understood that generally, the larger the contact area between the support table 140 and the flange portion 220, the more stable the assembly of the interface assembly 200; therefore, the structural form of the flange portion 220 and the support table 140 and the matching relationship between the two can be flexibly selected according to actual needs and will not be elaborated here.

[0089] In one embodiment, referring to Figures 3, 4, and 6 to 13, the interface assembly 200 further includes a tongue portion 230, primarily used to establish an electrical connection between the interface assembly 200 and an external plug. The tongue portion 230 has a predetermined length in the insertion direction of the interface assembly 200. Accordingly, the main body 210 defines a guide cavity 210a. The guide cavity 210 extends from the side of the main body 210 proximal to the accommodating cavity 111 toward the side distal to the accommodating cavity 111 and communicates with the exterior of the interface assembly 200. A portion of the tongue portion 230 is inserted into the guide cavity 210a, while another portion of the tongue portion 230 protrudes from the side of the guide cavity 210a distal to the accommodating cavity 111 (which can also be understood as the tongue portion 230 protruding from the side of the flange portion 220 distal to the accommodating cavity 111 in the insertion direction of the interface assembly 110).

[0090] By arranging the tongue portion 230 to protrude from the guide cavity 111 , the length dimension of the main body portion 210 in the insertion direction of the interface component 200 can be reduced, which is equivalent to reducing the length dimension of the accommodating groove 200 and saving the assembly space of the interface component 200 .

[0091] In some specific embodiments, for ease of distinction and description, please refer to Figure 6, the end face of the tongue portion 230 that is away from the main body portion 210 in the insertion direction of the interface component 200 is defined as a first end face, and the end face of the flange portion 220 that is away from the main body portion 210 in the insertion direction of the interface component 200 is defined as a second end face, and the height difference h between the first end face and the second end face can be controlled between 0.6mm-1.1mm.

[0092] Therefore, when the length of the tongue portion 230 is limited and cannot be changed, by selecting and setting the height difference between the tongue portion 230 and the flange portion 220, it is possible to ensure the plug-in strength between the interface component 200 and the external plug, and create conditions for reducing the size of the accommodating groove 200 and saving the assembly space of the interface component 200.

[0093] Further, referring to Figure 13, the wearable device also includes a seal 600, which is mainly used to selectively block the interface component 200; for example, when the interface component 200 is not inserted into the corresponding external plug, the seal 600 blocks the interface component 200, which can reduce the impact of dust particles and other impurities falling into the guide cavity 210a, or blocking the guide cavity 210a and affecting the normal use of the interface component 200; when the interface component 200 needs to be used, the seal 600 can be released from blocking the interface component 200.

[0094] Specifically, the seal 600 is arranged on the side of the main body 210 away from the accommodating cavity 111 facing the guide cavity 210a; the part of the tongue portion 230 protruding from the guide cavity 210a (hereinafter referred to as the protruding part of the tongue portion 230) can be used as a carrier for the interface component 200 and the seal 600 to be connected together, so as to position and assemble the seal 600 on the interface component 200 in a detachable or movable connection manner, thereby achieving shielding of the interface component 200; for example, the seal 600 can be placed on the protruding part of the tongue portion 230 and cover the guide cavity 210a.

[0095] In one embodiment, referring to Figures 5, 6, and 10, the main body 210 includes an inner housing 211 and an outer housing 212. The outer housing 212 is generally a tubular structure having a predetermined length in the insertion direction of the interface assembly 200. A portion of the inner housing 211 is inserted into the outer housing 212, while another portion protrudes from the outer housing 212. The inner housing 211 defines a guide cavity 210a. In some embodiments, the interior space of the inner housing 211 serves as the guide cavity 210a.

[0096] More specifically, for the convenience of distinction and description, one end of the inner shell 211 in the insertion direction of the interface assembly 200 is defined as the first end of the inner shell 211, and the other end of the inner shell 211 in the insertion direction of the interface assembly 200 is defined as the second end of the inner shell 211; wherein, the first end of the inner shell 211 is inserted into the outer shell 212 to form a glue-containing space 210b for accommodating waterproof glue between the inner side of the outer shell 212 and the outer side of the first end of the inner shell 211; the second end of the inner shell 211 is protruded from the outer shell 212 to form a flange portion 220; in specific implementation, the flange portion 220 can be formed by flanging the second end of the inner shell 211.

[0097] It can also be understood that the glue accommodating space 210b and the guide cavity 210a are formed inside the main body 210 and are isolated from each other along the insertion direction of the interface component 200, and the glue accommodating space 210b is closer to the accommodating cavity 111 than the guide cavity 210a, that is, the glue accommodating space 210b is located on the side of the guide cavity 210a close to the accommodating cavity 111.

[0098] In other embodiments, with regard to the flange portion 220, the flange portion 220 may also be provided only to protrude from the second end of the inner shell 211, for example, by flanging the second end of the inner shell 211 to form the flange portion 220; but the flange portion 220 does not protrude from the outer shell 212; at this time, the inner shell 211 may be completely inserted into the interior of the outer shell 212, or the second end of the inner shell 211 may be exposed to the outer shell 212, thereby forming interface assemblies 200 of different structural forms to meet different needs.

[0099] In some embodiments, a portion of the tongue portion 230 located in the guide cavity 210a can extend through the first end of the inner shell 211 into the glue space 210a, so as to establish an electrical connection between the interface assembly 200 and the circuit board 300 based on the cooperation between the tongue portion 230 and the wire assembly 400.

[0100] By using the glue space 210b as a storage space for waterproof glue, waterproof glue can be injected into the glue space 210b to form a waterproof structure on the side of the main body 210 near the accommodating cavity 111. This can not only effectively enhance the overall waterproof performance of the interface assembly 200, but also enhance the stability of the structural coordination between the outer shell 212 and the inner shell 211. In the process of dispensing glue into the glue space 210b, the side wall of the outer shell 212 can be used to confine the waterproof glue to the outside of the first end of the inner shell 211, effectively preventing the waterproof glue from overflowing. At the same time, in some embodiments, the flange portion 220 can be used to support the outer shell 212, thereby limiting the relative position between the outer shell 212 and the inner shell 211 and the volume size of the glue space 210b, thereby enhancing the structural strength of the main body 210 and even the entire interface assembly 200.

[0101] Further, referring to Figure 12 and in combination with Figure 10, the main body 210 also includes a reinforcement structure 213, which can be a plate-like structure welded and fixed to the first end of the inner shell 211 and located in the glue-containing space 210b, or a protruding structure arranged on the outer surface of the first end of the inner shell 211, etc.

[0102] On the one hand, the use of the reinforcement structure 213 can not only enhance the structural strength of the inner shell 211 itself, but also enhance the connection strength between the inner shell 211 and the waterproof glue, thereby enhancing the connection strength between the inner shell 211 and the outer shell 212, and improving the overall structural stability and reliability of the main body 210 and even the interface assembly 200.

[0103] On the other hand, the provision of reinforcement structure 213 also creates conditions for reducing the size of interface assembly 200 and lowering the spatial requirements for receiving slot 112. For example, in general, to ensure sufficient structural strength and good waterproof performance for main body 210, the wall thickness of inner shell 211 and outer shell 212 is typically set to 0.3mm-0.4mm, and the thickness of the waterproof adhesive (i.e., the thickness of the waterproof adhesive within adhesive space 210b in the insertion direction of interface assembly 200) is typically set to approximately 0.7mm.

[0104] However, by providing reinforcement structure 213, the wall thickness of inner housing 211 and outer housing 212 can be adjusted to between 0.1mm and 0.3mm (e.g., approximately 0.15mm), while the thickness of the waterproof adhesive can be maintained at approximately 0.7mm. Thus, by reducing the wall thickness of inner housing 211 and outer housing 212, the size of interface assembly 200 can be reduced, thereby saving assembly space and further facilitating the miniaturization of the wearable device.

[0105] In some embodiments, please refer to Figure 12. As for the tongue portion 230, the end of the tongue portion 230 extending into the glue-containing space 210b can be fixedly connected to the inner shell 211 (for example, by welding) with the aid of a reinforcing structure 213 to enhance the connection strength between the tongue portion 230 and the main body portion 210, thereby further improving the structural stability of the interface assembly 200.

[0106] In one embodiment, referring to Figures 3 to 6 and 10, the interface component 200 further includes an external circuit board 240, which is disposed on a side of the main body 210 close to the accommodating cavity 111 (i.e., the side of the main body 210 facing away from the flange portion 220). The interface component 200 is electrically connected to the wire component 400 through the external circuit board 240, and then an electrical connection is established between the interface component 200 and the circuit board 300 using the wire component 400.

[0107] With the help of the external circuit board 240, the circuits originally set on the circuit board 300 and related to the interface component 200 (such as voltage and current stabilization circuits, etc.) can be transferred and set in the external circuit board 240. This not only reduces the size of the circuit board 300 and its requirements for the spatial size of the accommodating cavity 111, creating conditions for the miniaturization design of wearable devices, but also realizes the integration of interface functions, which is conducive to a more reasonable arrangement of the accommodating cavity 111 and the accommodating groove 112, and enhances the flexibility of assembly of the circuit board 300 and the interface component 200.

[0108] As for wearable devices, please refer to Figures 1 and 3. The external circuit board 240 can be arranged horizontally in the accommodating groove 112 relative to the circuit board 300, that is, the plane where the external circuit board 240 is located intersects with the plane where the circuit board 300 is located at an angle (for example, perpendicularly intersecting); in this way, the assembly space of the circuit board 300 and the interface component 200 can be further saved, and the structural space of the shell component 100 can be fully utilized.

[0109] In some embodiments, with respect to the tongue plate portion 230, the terminal pins of the tongue plate portion 230 can be directly welded to the external circuit board 240. On the one hand, an electrical connection is established between the tongue plate portion 230 and the external circuit board 240. On the other hand, the external circuit board 240 is fixed to the side of the main body portion 210 close to the accommodating cavity 111 to construct a complete structure of the interface assembly 200, so that the interface assembly 200 can be used as an independent functional component in a wearable device.

[0110] It should be noted that Figures 1 and 3 only use headphones as an example to illustrate the general structural structure of the wearable device of the embodiment of the present application, but headphones are only a specific embodiment of the wearable device, and the wearable device can also be other devices such as glasses and watches.

[0111] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
