Meanwhile, the steps or actions in the method description can also be sequentially changed or adjusted in a manner that can be apparent to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0058] The serial numbers of the components in the specification, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in the present application include direct and indirect connection (coupling) unless otherwise specified.

[0059] In this paper, the wearable device provided by the embodiments of the application is described mainly by taking the in-ear hearing aid as an example; it should be noted that the in-ear hearing aid is only a specific embodiment of the actual application of the wearable device, and the wearable device can also be other types of hearing aids, earphones, glasses and other devices.

[0060] Please refer to FIG. 1, the wearable device includes a shell assembly 100, a core assembly, a speaker device, and other functional components as needed.

[0061] The core assembly can be understood as a collection of related components that implement the main functions of the wearable device, for example, the core assembly can support the implementation of functions such as sound signal collection, electrical signal conversion processing, device on-off, volume adjustment, power supply, etc.; The core assembly is arranged in the shell assembly 100 to form a complete functional structure with the shell assembly 100; In order to distinguish and describe, the combination structure of the shell assembly 100 and the core assembly is defined as the device main body.

[0062] The speaker device can be understood as a collection of related components that implement the function of playing sound signals of the wearable device. In some embodiments, the speaker device is connected and arranged with the device main body, that is, the speaker device is connected and arranged outside the shell assembly 100.

[0063] Exemplarily, please refer to FIG. 1, the speaker device is an in-ear speaker, which includes a speaker assembly 810 and a wearing assembly 820; wherein the speaker assembly 810 is arranged in a structure form that can be adaptively inserted into the ear canal of the user, mainly playing the role of playing sound signals to the user; The wearing assembly 820 is connected and arranged between the speaker assembly 810 and the shell assembly 100 in the form of electrically connecting the speaker assembly 810 and the core assembly, mainly for establishing a signal connection relationship between the core assembly and the speaker assembly 810.

[0064] The wearing assembly 820 can adopt a flexible cable with signal transmission function, or other wire with signal transmission function and shape memory function. One end of the wearing assembly 820 is fixed and electrically connected with the speaker assembly 810, and the other end of the wearing assembly 820 can be connected to the shell assembly 100 in a detachable or non-detachable manner and electrically connected with the core assembly.

[0065] With the wearing assembly 820, the device body can be stably worn on the ear of the user, and the speaker assembly 810 can be inserted into the ear canal of the user; through the device body (specifically, the core assembly), external sound signals can be collected, and the sound signals can be converted into electrical signals and output to the speaker assembly 810, so that the corresponding sound signals can be played by the speaker assembly 810 to realize the hearing aid function of the wearable device.

[0066] In other embodiments, the speaker device can also be configured in other forms in the wearable device, for example, the core assembly is directly arranged inside or outside the shell assembly 100 to form a wearable device with different structural forms or different functions; that is, by selecting and configuring the speaker device, the device body, and the structural relationship therebetween, other structural forms of hearing aids or earphones, glasses, and other types of wearable devices can also be constructed.

[0067] It can be understood that when the wearable device is in a powered-on state, the conversion between the sound signal (such as a mechanical vibration signal) and the electrical signal can be realized through the cooperation of the core assembly and the speaker device, so that the user can hear the sound through the ear. Generally, mechanical vibration can act on the tympanic membrane of the user based on the air conduction principle and mainly through air as a medium, and then act on the auditory nerve; mechanical vibration can also act directly on the auditory nerve of the user through the user's bones and tissues as a medium based on the bone conduction principle; for the sound heard by the user, the former can be referred to as "air conduction sound", and the latter can be referred to as "bone conduction sound".

[0068] Therefore, by selecting and configuring the specific functional structures of the core assembly and the speaker device, the wearable device can form air conduction sound, bone conduction sound, or both air conduction sound and bone conduction sound.

[0069] In order to more clearly and specifically describe the structure of the device body, based on the outer contour form of the device body, three directions intersecting or perpendicular to each other are defined in this paper, namely "first direction", "second direction" and "third direction".

[0070] Exemplarily, in a certain natural placement state of the wearable device, the first direction can refer to the length direction of the device as a whole, the second direction can refer to the thickness direction of the device as a whole, and the third direction can refer to the width direction of the device as a whole.

[0071] Exemplarily, in a state where the wearable device is normally worn between the back of the ear and the head, with the user as a reference, the first direction can refer to the up-down direction of the user, the second direction can refer to the front-back direction of the user, and the third direction can refer to the left-right direction of the user.

[0072] In one embodiment, referring to FIGS. 1-7, the housing assembly 100 includes a first housing 110 and a second housing 120; the first housing 110 and the second housing 120 are opposite to each other and connected in cooperation to enclose a receiving cavity 100a in the interior of the housing assembly 100 (or between the first housing 110 and the second housing 120); a movement core assembly is arranged in the receiving cavity 100a; wherein at least a part of the movement core assembly 100 is connected and arranged on the first housing 110, and at least another part of the movement core assembly 100 is connected and arranged on the second housing 120.

[0073] Exemplarily, the movement core assembly includes a control board assembly 200, a microphone assembly 300, a key assembly 400, a first interface assembly 500, a second interface assembly 600, and a battery assembly 700; for the convenience of distinguishing and describing, the functional components in the movement core assembly connected with the first housing 110 are defined as the first assembly, and the functional components in the movement core assembly connected with the second housing 120 are defined as the second assembly. Wherein, the first assembly can include the control board assembly 200, the microphone assembly 300, and the key assembly 400; the second assembly can include the first interface assembly 500, the second interface assembly 600, and the battery assembly 700.

[0074] The microphone assembly 300 is electrically connected with the control board assembly 200 and is fixed on the first housing 1100 respectively; the microphone assembly 300 is mainly used for collecting sound signals outside the device (specifically, outside the housing assembly 100), for example, mechanical vibration of the related components of the microphone assembly 300 itself caused by external environmental sound, so that the microphone assembly 300 realizes the collection of sound signals.

[0075] The control board assembly 200 mainly plays a role of regulation and management in the wearable device, for example, the control board assembly 200 can receive the sound signals collected by the microphone assembly 300, and then convert the sound signals into electrical signals and output to a loudspeaker device (specifically, a loudspeaker assembly 810), so as to play the sound signals to the user by means of the loudspeaker device.

[0076] The key assembly 400 is movably connected to the first shell 1100 and cooperatively arranged with the control board assembly 200. Through cooperation between the key assembly 400 and the control board assembly 200, the input of preset instructions can be realized. For example, through the key assembly 400, the control board assembly 200 can be inputted with instructions for controlling the wearable device to start and shut down, instructions for adjusting the volume, or other instructions.

[0077] The first interface assembly 500, the second interface assembly 600, and the battery assembly 700 are connected to the second shell 120 and electrically connected to the control board assembly 200. For example, an electrical signal connection relationship is established between the control board assembly 200 and the battery assembly 700 through a wire assembly. Among them, the first interface assembly 500 mainly plays a role of connecting the speaker device in the device main body. For example, in a pluggable form, the first interface assembly 500 is detachably connected to the wearing assembly 820, so as to establish a signal connection relationship between the speaker assembly 810 and the control board assembly 200, so that the speaker assembly 810 can generate or play a sound signal due to the electrical signal provided by the control board assembly 200.

[0078] The second interface assembly 600 is mainly used for connecting external control devices (such as mobile phones, computers, etc.) to perform data transmission between the external control devices and the wearable device. For example, through the external control device, the working mode, working parameters, volume size, etc. of the wearable device can be adaptively adjusted according to the user's needs. The battery assembly 700 is mainly used for powering the power components in the wearable device to provide support for the normal work of the wearable device.

[0079] In some embodiments, other functional components can also be added or some functional assemblies can be omitted in the movement core assembly. For example, the first interface assembly 500 can be omitted, and the speaker assembly 810 can be directly connected to the control board assembly 200 through the wearing assembly 820. For another example, the second interface assembly 600 is replaced by a wireless communication module, and data transmission is performed between the wearable device and the external control device through the wireless communication module.

[0080] That is, the movement core assembly can include one or more of the control board assembly 200, the microphone assembly 300, the key assembly 400, the first interface assembly 500, the second interface assembly 600, and the battery assembly 700.

[0081] In some embodiments, based on the structure form inside the shell assembly 100, the functional assemblies in the first assembly and the second assembly can also be arranged in a reciprocal manner. For example, the first interface assembly 500 belongs to the first assembly and is connected to the first shell 110.

[0082] That is, the control board assembly 200, the microphone assembly 300, the button assembly 400, the first interface assembly 500, the second interface assembly 600, and the battery assembly 700, etc. can be selectively connected to the first shell 110 or the second shell 120 according to the structural layout and functional configuration of the shell assembly 100 or the device body.

[0083] It should be noted that the description of the "wire assembly" is introduced in this paper, which can be a wire, a wire, a flexible printed circuit (FPC), etc. to adapt to the internal structure of the shell assembly 100 and the spatial arrangement relationship between the related functional assemblies, so as to flexibly establish the electrical connection relationship between the related functional assemblies.

[0084] Based on this, by taking the first shell 110 and the second shell 120 as the mounting carrier of the plurality of functional components inside the device, the movement assembly can be dispersedly arranged at different parts of the shell assembly 100. On the one hand, compared with the related art which uses the internal skeleton of the shell assembly 100 as the mounting carrier of the movement assembly, the present application can realize the full use of the shell structure and space, reduce the number of internal components of the device, thereby facilitating the miniaturization and lightweight design of the wearable device. On the other hand, based on the structure of the dispersed arrangement of the movement assembly, not only can the wearable device be quickly disassembled and combined, but also by disassembling the first shell 110 and the second shell 120, the first assembly and the second assembly can be targeted for disassembly, maintenance, recycling, etc.

[0085] In one embodiment, referring to FIGS. 4-7, the first shell 110 and the second shell 120 both adopt a shell structure with an opening, and the first shell 110 and the second shell 120 are connected in the form of opening each other in the second direction to form a containing cavity 100a.

[0086] As for the movement assembly, the first assembly (such as the control board assembly 200, the microphone assembly 300, the button assembly 400, etc.) is connected with the inner wall of the first shell 110, so that at least part of the first assembly is accommodated in the shell space of the first shell 110; the second assembly (such as the first interface assembly 500, the second interface assembly 600, the battery assembly 700, etc.) is connected with the inner wall of the second shell 120, so that at least part of the second assembly is accommodated in the shell space of the second shell 120.

[0087] Firstly, by connecting the first component with the inner wall of the first housing 110 and connecting the second component with the inner wall of the second housing 120, the connection structure between the movement assembly and the housing assembly 100 can be prevented from affecting the appearance contour of the device main body and improving the appearance aesthetics and wearability of the device main body.

[0088] Secondly, by accommodating the first component and the second component in the housing space of the first housing 110 and the second housing 120, a certain protection effect can be achieved to prevent the first component or the second component from being damaged due to bumping before the housing assembly 100 is assembled.

[0089] Thirdly, by setting the first housing 110 and the second housing 120 as a housing structure with a certain volume space inside and an opening, the first housing 110 and the first component and the second housing 120 and the second component can be respectively assembled, and after the wiring of the wire assembly is completed, the assembly of the device main body can be conveniently and quickly completed.

[0090] In some embodiments, the first housing 110 can adopt a housing structure with an opening, and the second housing 120 can adopt a cover plate structure; the second housing 120 is arranged in the form of covering the opening of the first housing 110 on the first housing 110 to form a containing cavity 100a with the first housing 110; as for the movement assembly, the first component is connected to the inner wall of the first housing 110 and accommodated in the housing space of the first housing 110; the second component is connected to the side of the second housing 120 facing the first housing 110; after the first housing 110 and the second housing 120 are combined, the second component is equivalent to being accommodated in the housing space (i.e., the containing cavity 100a) of the first housing 110. Of course, the first housing 110 can adopt a cover plate structure, and the second housing 120 can adopt a housing structure with an opening.

[0091] Therefore, the housing assembly 100 is combined in the form of a housing structure cooperating with a cover plate structure, which not only facilitates the rapid assembly of the device main body, but also can form wearable devices with different structural forms or assembly methods to meet different application requirements.

[0092] In one embodiment, referring to FIGS. 4 to 7, an assembly structure is provided between the first housing 110 and the second housing 120, which is mainly used to assemble and fix the first housing 110 provided with the first component and the second housing 120 provided with the second component as a whole to form the complete outer contour structure (i.e., the housing assembly 100) of the device main body, so that the wearable device or the device main body can be moved, carried, worn, operated and used by means of the housing assembly 100.

[0093] The assembly structure can adopt different structures according to the connection form between the first shell 110 and the second shell 120, for example, the assembly structure can be a related structure suitable for realizing the connection form of glue joint, welding, etc. between the first shell 110 and the second shell 120, and for another example, the assembly structure can also be a related structure suitable for realizing the detachable connection form of clamping, locking, etc. between the first shell 110 and the second shell 120.

[0094] Exemplarily, referring to FIGS. 4-7, the assembly structure includes a first fixing structure and a first positioning structure; wherein the first fixing structure is mainly used for stably fixing the first shell 110 and the second shell 120 as a whole; the first positioning structure is mainly used for positioning the relative position between the first shell 110 and the second shell 120, so as to provide support for quickly and accurately assembling the first shell 110 and the second shell 120, while cooperating with the first fixing structure to enhance the structural combination strength of the first shell 110 and the second shell 120.

[0095] The first fixing structure includes a support arm 131 and a fixing pin 132; wherein the support arm 131 is provided protruding from the inner wall surface of the second shell 120, for example, the support arm 131 is an integral structure with the second shell 120; the fixing pin 132 cooperates with the support arm 131.

[0096] The first positioning structure includes a first positioning protrusion 141 and a first positioning slot hole 142; wherein the first positioning protrusion 141 is provided protruding from the inner wall surface of the first shell 110, and the first positioning protrusion 141 is an integral structure with the first shell 110; the first positioning slot hole 142 is integrally formed in the second shell 120 at a position corresponding to the first positioning protrusion 141.

[0097] In the process of assembling the first shell 110 and the second shell 120 to form the shell assembly 100, the first positioning protrusion 141 can be pre-inserted into the first positioning slot hole 142 by means of the alignment relationship between the first positioning protrusion 141 and the first positioning slot hole 142, thereby limiting the relative position of the first shell 110 and the second shell 120, for example, the open end surface of the first shell 110 and the open end surface of the second shell 120 abut each other, so that the first space and the second space are communicated to form the accommodation cavity 100a (at this time, the support arm 131 is located in the accommodation cavity 100a).

[0098] Then, the fixing pin 132 is inserted into the interior of the shell assembly 100 from the exterior of the shell assembly 100 through a position of the first shell 110 corresponding to the support arm 131 (for example, a pin hole structure can be provided at the position of the first shell 110 corresponding to the support arm 131), thereby penetrating and fixing the first shell 110 and the support arm 131 as a whole, so as to finally realize the detachable assembly and fixation between the first shell 110 and the second shell 120.

[0099] In some embodiments, the support arm 131 and the fixing pin 132, the first positioning protrusion 141 and the first positioning slot hole 142 can also be arranged in a position exchange manner; for example, the support arm 131 is arranged protruding from the inner wall of the first shell 110, and the first positioning protrusion 141 is arranged protruding from the inner wall of the second shell 120.

[0100] By means of the cooperation between the first fixing structure and the first positioning structure, the assembly and fixing of the first shell 110 and the second shell 120 can be conveniently and accurately realized, so as to effectively enhance the structural stability of the shell assembly 100 (or the equipment shell), and provide structural support for the disassembly and assembly of the equipment main body or the shell assembly 100.

[0101] For example, in the process of assembling the equipment main body or the shell assembly 100, the first positioning protrusion 141 can be first inserted into the corresponding first positioning slot hole 142, and then the fixing pin 132 is inserted by means of the cooperation between the support arm 131 and the fixing pin 132, so as to finally assemble and fix the first shell 110 and the second shell 120 to form the shell assembly 100; in this way, the accuracy of the combined assembly of the first shell 110 and the second shell 120 can be ensured.

[0102] For example, when the equipment main body needs to be disassembled for maintenance, the shell assembly 100 can be disassembled by pulling out the fixing pin 132, so as to check and maintain the structure and related components inside the equipment main body.

[0103] In some embodiments, the first fixing structure and the first positioning structure can also adopt other structural forms.

[0104] For example, a plurality of buckle structures that cooperate with each other are arranged on the first shell 110 and the second shell 120, and the buckle structures are used to replace the first fixing structure and the first positioning structure, so as to realize the assembly and fixing of the first shell 110 and the second shell 120.

[0105] For another example, a shaft structure is arranged on the inner wall of the first shell 110 corresponding to the position of the support arm 131, and a pin hole structure is arranged on the support arm 131 for the shaft structure to be inserted, the first fixing structure is formed by the cooperation between the shaft structure and the pin hole structure, so that the first shell 110 and the second shell 120 are positioned and fixed from different positions and different directions under the cooperation of the first positioning structure.

[0106] In some embodiments, the first fixing structure can also be omitted, and one or more first positioning structures are arranged to pre-position the first shell 110 and the second shell 120, and then the first shell 110 and the second shell 120 are finally fixed by means of gluing, welding or the like.

[0107] Of course, the first positioning structure can be omitted, and the first housing 110 and the second housing 120 can be fixedly connected from multiple different positions by setting multiple groups of support arms 131 and fixing pins 132. All of these will not be repeated here.

[0108] In one embodiment, referring to FIGS. 4 and 5, the first housing 110 and the second housing 120 are oppositely and fittingly connected in the second direction to form the housing assembly 100, and the first fixing structure and the first positioning structure are arranged at the two opposite ends of the housing assembly 100 in the first direction. For the convenience of description, the two opposite ends of the housing assembly 100 in the first direction or the length direction can be defined as the first end and the second end of the housing assembly 100. In the normal wearing state of the wearable device, the first end of the housing assembly 100 can be the upper end of the housing assembly 100, and the second end of the housing assembly 100 can be the bottom end of the housing assembly 100. The first fixing structure is arranged at the first end of the housing assembly 100, and the first positioning structure is arranged at the second end of the housing assembly 100.

[0109] By arranging the first fixing structure and the first positioning structure at the two opposite ends of the housing assembly 100, the first housing 110 and the second housing 120 can be pre-positioned and combined by means of the first positioning structure during assembly, and then the first housing 110 and the second housing 120 can be fixed by using the cooperation relationship between the fixing pin 132 and the support arm 131. In this way, it is beneficial for the assembly personnel to quickly and accurately identify the assembly direction of the first housing 110 and the second housing 120, thereby improving the assembly efficiency of the housing assembly 100 or the device main body. At the same time, it is also convenient to check and maintain the internal structure and related functional components of the housing assembly 100 by disassembling the housing assembly 100.

[0110] In some embodiments, the control board assembly 200, the microphone assembly 300, etc. are connected to the inner wall of the first housing 110, the first interface assembly 500, the battery assembly 700, etc. are connected to the inner wall of the second housing 120, and the first housing 110 and the second housing 120 both adopt a shell structure. The support arm 131 is arranged to protrude from the inner wall of the second housing 120 toward the side where the first housing 110 is located along the second direction. The fixing pin 132 is arranged to pass through the first housing 110 and the support arm 131 along the third direction. Correspondingly, the first positioning protrusion 141 is arranged to protrude from the inner wall or the open end surface of the second housing 120 toward the side where the second housing 120 is located along the second direction.

[0111] Therefore, based on the differential arrangement of the arrangement directions of the support arm 131 and the first positioning protrusion 141, the combination of the second housing 120 and the second assembly can be regarded as a mounting body, which guides the assembly personnel to quickly and accurately assemble the combination structure of the first housing 110 and the first assembly to the mounting body.

[0112] In one embodiment, referring to FIGS. 2-12, the first shell 110 and the second shell 120 are both in a shell structure, and the core assembly includes a control board assembly 200, a microphone assembly 300, a button assembly 400, a first interface assembly 500, a second interface assembly 600, and a battery assembly 700.

[0113] For the sake of distinction and description, the two shell walls of the first shell 110 opposite to each other in the first direction are defined as a first shell wall 110a and a second shell wall 110b, the two shell walls opposite to each other in the third direction are defined as a third shell wall 110c and a fourth shell wall 110d, and the shell wall connecting the first shell wall 110a, the second shell wall 110b, the third shell wall 110c, and the fourth shell wall 110d in the second direction is defined as a fifth shell wall 110e.

[0114] The two shell walls of the second shell 120 opposite to each other in the first direction are defined as a sixth shell wall 120a and a seventh shell wall 120b, the two shell walls opposite to each other in the third direction are defined as an eighth shell wall 120c and a ninth shell wall 120d, and the shell wall connecting the sixth shell wall 120a, the seventh shell wall 120b, the eighth shell wall 120c, and the ninth shell wall 120d in the second direction is defined as a tenth shell wall 120e.

[0115] Among them, the first shell wall 110a and the sixth shell wall 120a combine to form a first side wall of the shell assembly 100, the second shell wall 110b and the seventh shell wall 120b combine to form a second side wall of the shell assembly 100, the fifth shell wall 110e and the tenth shell wall 120e can be understood as a third side wall and a fourth side wall opposite to each other in the second direction of the shell assembly 100, the third shell wall 110c and the eighth shell wall 120c combine to form a fifth side wall of the shell assembly 100, and the fourth shell wall 110d and the ninth shell wall 120d combine to form a sixth side wall of the shell assembly 100. It can be understood that the first side wall, the second side wall, the third side wall, the fourth side wall, the fifth side wall, and the sixth side wall of the shell assembly 100 are connected to form a receiving cavity 100a.

[0116] Referring to FIGS. 2, 3, and 8, the control board assembly 200 is arranged inside the shell assembly 100, for example, fixedly connected to the third side wall (i.e., the fifth shell wall 110e); the microphone assembly 300 can be a collection of related functional devices capable of forming "air conduction sound", and the microphone assembly 300 is fixedly arranged at the third side wall and in air communication with the outside of the shell assembly 100 at the third side wall.

[0117] Exemplarily, a sound pickup hole 110f can be provided through the third side wall (i.e., the fifth shell wall 110e) at a position corresponding to the microphone assembly 300, the sound pickup hole 110f being arranged in communication with the microphone assembly 300, and external sound signals being conducted to the microphone assembly 300 via air as a medium to cause the microphone assembly 300 to collect sound signals by generating mechanical vibrations.

[0118] Exemplarily, a sound guide pipe can also be arranged in the accommodating cavity 100a, and the microphone assembly 300 is in communication with the outside of the shell assembly 100 through the sound guide pipe, so as to realize collection of sound signals.

[0119] In some embodiments, referring to FIG. 2, the number of microphone assemblies 300 is two, and the two microphone assemblies 300 are arranged on opposite sides of the control board assembly 200 in the first direction; in terms of the device main body, the two microphone assemblies 300 can be used to collect sound signals from different directions.

[0120] Referring to FIGS. 2 and 3, the key assembly 400 is arranged in the accommodating cavity 100a in a form of being movably connected (for example, rotationally connected, slidably connected, etc.) to the inner wall of the first shell 110, and the key assembly 400 is at least partially exposed outside the third side wall.

[0121] For example, the key assembly 400 is arranged on the side of the control board assembly 200 in the second direction facing the third side wall, a key window 110g is provided through the third side wall at a position corresponding to the key assembly 400, and the key assembly 400 is exposed and arranged protruding out of the third side wall through the key window 110g.

[0122] By applying a pressing force to the key assembly 400 towards the side of the control board assembly 200, the key assembly 400 can be caused to press the key switch on the control board assembly 200 to realize input of a preset instruction.

[0123] In some embodiments, the key assembly 400 can also include a switch component capable of generating an electrical signal, and the key assembly 400 is arranged in electrical connection with the control board assembly 200 to input instruction information to the control board assembly 200 by triggering the key assembly 400.

[0124] Referring to FIGS. 2, 3 and 6, the first interface assembly 500 is arranged in the accommodating cavity 100a in a form of being at least partially exposed outside the first side wall and fixedly connected (for example, fixed to the fourth side wall) with the second shell 120; exemplarily, a first connecting port 120f can be provided through the first side wall, an interface end of the first interface assembly 500 can be arranged in direct communication with the first connecting port 120f, the interface end of the first interface assembly 500 can also extend into the first connecting port 120f, and the first interface assembly 500 can also extend out of the shell assembly 100 from the first connecting port 120f.

[0125] Correspondingly, the interface structure capable of being pluggably and adaptively connected with the first interface assembly 500 can be arranged at the speaker device (specifically, the end of the wearing assembly 820 away from the speaker assembly 810), and the interface structure is used to fix the speaker device and the device main body by means of the first interface assembly 500, and to realize the electrical connection between the speaker device and the movement assembly (for example, the control board assembly 200).

[0126] Please refer to FIG. 2, FIG. 3 and FIG. 6, the second interface assembly 600 is fixedly connected (for example, fixed to the fourth side wall) with the second shell 120 in the form of at least partially exposed to the fifth side wall and arranged in the accommodating cavity 100a; for example, the second connecting port 120g can be arranged through the fifth side wall (for example, the eighth shell wall 120c), and the interface end of the second interface assembly 600 can be arranged opposite to and communicated with the second connecting port 120g, and the interface end of the second interface assembly 600 can also extend into the second connecting port 120g. In the wearable device application stage, the mobile phone, computer and other external control devices can be connected by means of the second interface assembly 600, so as to adaptively adjust the working mode, working parameter and the like of the wearable device according to the user's own needs.

[0127] Please refer to FIG. 2, FIG. 4 and FIG. 6, the battery assembly 700 can be fixedly connected to the second shell 120 or movably connected to the second shell 120; for example, the battery window 120h can be arranged at the region where the second side wall meets the fourth side wall, and the battery assembly 700 is movably connected to the second shell 120, so that the battery assembly 700 can enter and exit the accommodating cavity 100a through the battery window 120h by rotating the battery assembly 700, so as to replace the battery.

[0128] Therefore, by dispersing the parts of the movement assembly at different positions or different orientations of the shell assembly 100, the structure and space of the shell assembly 100 can be more reasonably utilized, the performance of the device is ensured, and the wearable device is facilitated to be operated.

[0129] For example, by arranging the first interface assembly 500 and the battery assembly 700 at the opposite ends of the device main body along the first direction, the key assembly 400 is arranged along the first direction at the position between the first interface assembly 500 and the battery assembly 700; on the one hand, it is not only convenient to connect the speaker device (for example, the wearing assembly 820) by means of the first interface assembly 500, but also convenient to replace the battery in the battery assembly 700; on the other hand, in the wearing state of the device, the key assembly 400 can be located at the middle or lower position of the rear side of the device main body, so that the key assembly 400 is facilitated to be operated, and the structure interference of the first interface assembly 500 and the battery assembly 700 to the key assembly 400 is avoided.

[0130] For example, by setting the third side wall as an arc surface structure, and arranging the two microphone assemblies 300 on the opposite sides of the key assembly 400 or the control board assembly 200 in the first direction, the sound pickup holes 110f corresponding to the two microphone assemblies 300 can be directed to different directions, so that the external sound signals can be effectively prevented from being blocked by the user's body parts, and the sound signal collection effect of the microphone assemblies 300 can be ensured.

[0131] In some embodiments, when the wearable device is in a normal wearing state, for example, the device body is hung on the back side of the user's ear by means of the wearing assembly 820, and the speaker assembly 810 is inserted into the user's ear canal:

[0132] The first side wall is a side wall facing the front side of the user in the first direction, the second side wall is a side wall facing the lower side of the user's ear in the first direction, the third side wall is a side wall facing away from the region where the user's head and the back side of the ear meet in the second direction, the fourth side wall is a side wall facing or contacting the region where the user's head and the back side of the ear meet in the second direction, the fifth side wall is a side wall facing or contacting the back side of the user's ear in the third direction, and the sixth side wall is a side wall facing or contacting the user's head in the third direction.

[0133] Please refer to FIGS. 1-3 and 5, the size of the shell assembly 100 in the first direction is greater than the size of the shell assembly 100 in the second and third directions; the third and fourth side walls are set as arc surface structures that can adapt to the physiological structure of the region where the back side of the ear meets the head. In terms of the geometric center line of the shell assembly 100 in the first direction, the geometric center line is set as an arc segment.

[0134] In this way, based on the size difference of the shell assembly 100 in different directions and the structural form of the side walls, the outer contour of the shell assembly 100 or the device body is constructed as a profile structure, so that the shell assembly 100 or the device body can adapt to the physiological structure between the back side of the ear and the head, and thus can be worn in the form of being clamped or hung on the ear.

[0135] In the embodiment in which the shell assembly 100 adopts a profile structure, the size of the shell assembly 100 in the third direction can be set to gradually decrease from the side where the second side wall is located to the side where the first side wall is located; that is, the size of the first end of the shell assembly 100 in the third direction is smaller than the size of the second end of the shell assembly 100 in the third direction. In this way, the width size of the end of the device body in the first direction for connecting the speaker (i.e., the end where the first interface assembly 500 is located) can be smaller than the width size of the end where the battery assembly 500 is located, so that the space size requirement of the battery assembly 500 on the shell assembly 100 can be met.

[0136] In some embodiments, the shell assembly 100 is made of polyimide (PI) material, for example, the first shell 110 and the second shell 120 are both made of an integral structure of polyimide material, and are connected to each other to form the shell assembly 100.

[0137] Compared with the related art, the body shell of the wearable device is usually made of polycarbonate (PC) material, ABS plastic (i.e., a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S)) and the like; in the present embodiment, based on the characteristics of good biocompatibility and mechanical strength of the polyimide material, the structure and appearance of the shell assembly 100 can be more stable, and the thickness of the shell wall is thinner, which is conducive to the miniaturization and light weight of the wearable device, and enhances the stability of the overall structure of the shell assembly 100.

[0138] In one embodiment, referring to FIGS. 2, 3, and 7-12, the shell assembly 100 includes the first shell 110, and the movement core assembly includes the microphone assembly 300; wherein the first shell 110 adopts a shell structure with an opening, and the first shell 110 has a sound pickup channel 110f passing through the fifth shell wall 110e to communicate the accommodation cavity 100a with the outside of the shell assembly 100. The microphone assembly 300 can be understood as a collection of devices capable of forming "air conduction sound", which is arranged in the accommodation cavity 100a (i.e., in the shell space of the first shell 110) and fixed to the inner wall (e.g., the fifth shell wall 110e) of the first shell 110, and the sound inlet channel of the microphone assembly 300 is in sealed communication with the sound pickup channel 110f.

[0139] In this way, the first shell 110 is used as the mounting carrier of the microphone assembly 300, which not only makes full use of the structural space of the shell assembly 100, but also reduces the number of related components, thereby providing support for the light weight and miniaturization of the wearable device. By using the sealed communication relationship between the microphone assembly 300 and the sound pickup channel 110f, the external sound signal can enter the sound inlet channel of the microphone assembly 300 through the sound pickup channel 110f with air as the medium, to cause the mechanical vibration of the related devices of the microphone assembly 300, thereby realizing the collection of the external sound signal through the collection and conversion of the mechanical vibration signal.

[0140] It should be noted that those skilled in the art should know the basic working principle of air conduction microphone, so the specific process and principle of the microphone assembly 300 collecting sound signal are not described here.

[0141] In one embodiment, the number of sound pickup channels 110f and microphone assemblies 300 is two, two sound pickup channels 110f and two microphone assemblies 300 are in one-to-one correspondence and sealed communication, and taking the sound pickup channel 110f as an example, the sound inlet ends of the two sound pickup channels 110f are arranged at intervals from each other, so as to cooperate with the microphone assembly 300 to collect external sound signals at different positions or different orientations.

[0142] Exemplarily, the third side wall (i.e., the fifth shell wall 110e) of the shell assembly 100 adopts an arc surface structure, and the sound inlet ends of the two sound pickup channels 110f are arranged at intervals on the outer surface of the third side wall in the first direction; it can also be understood that the surface of the shell assembly 100 on which the sound inlet ends of the sound pickup channels 110f are arranged can be defined as a first surface, and the first surface is an arc surface structure with a preset length in the first direction, and the sound inlet ends of the two sound pickup channels 110f are arranged at intervals from each other in the length direction of the first surface. Thus, based on the characteristics of the arc surface structure, the microphone assembly 300 can collect external sound signals from different orientations, thereby effectively avoiding the obstruction of the external sound signals by the user's body parts and ensuring the sound signal collection effect of the microphone assembly 300.

[0143] In other embodiments, according to the differences in the functional configuration or structural form of the microphone assembly 300, the two sound pickup channels 110f can also be simultaneously arranged in sealed communication with the sound inlet channel of the same microphone assembly 300 to meet different application requirements.

[0144] In one embodiment, referring to FIGS. 9-11, the microphone assembly 300 includes a first circuit board 310, a microphone 320, and a protective net 330; the protective net 330 is fixed to the inner surface of the fifth shell wall 110e in a form of covering the sound outlet ends of the sound pickup channels 110f, for example, the protective net 330 is fixed to the fifth shell wall 110e by adhesive bonding; the first circuit board 310 is fixed to the side of the protective net 330 opposite to the sound pickup channels 110f (for example, the first circuit board 310 is fixed to the protective net 330 by adhesive bonding), and the microphone 320 is arranged on the side of the first circuit board 310 opposite to the protective net 330, and the first circuit board 310 is provided with a sound guide channel 310a corresponding to the sound inlet channel of the microphone 320.

[0145] Among them, the microphone 320 is the main component for collecting sound signals in the microphone assembly 300, and the first circuit board 310 is the mounting carrier of the microphone 320, and the first circuit board 310 establishes an electrical signal connection relationship between the microphone 320 and the control board assembly 200.

[0146] On one hand, based on the cooperation between the first circuit board 310 and the protective net 330, the microphone 320 can be stably fixed to the first shell 110, so that the sound inlet channel of the microphone 320 can be kept in coaxial sealed communication with the sound pickup hole 110a through the sound guide hole 310a; on the other hand, the protective net 330 can prevent the water, dust and other pollutants outside the device from invading the microphone assembly 300 through the sound pickup hole 110f, so as to provide protection for the normal work of the microphone assembly 300.

[0147] In other embodiments, the microphone assembly 300 can also adopt other structural forms, for example, the protective net 330 is omitted, the microphone 320 is arranged on the side of the first circuit board 310 facing the sound pickup hole 110f, and the sound inlet channel of the microphone 320 can be directly sealed and communicated with the sound pickup hole 110f by means of the structural relationship between the first circuit board 310 and the first shell 110.

[0148] In one embodiment, referring to FIGS. 9 and 11, the microphone assembly 300 further comprises a reinforcing plate 340, which is fixed between the first circuit board 310 and the protective net 330, for example, is pasted between the first circuit board 310 and the protective net 330; the material hardness of the reinforcing plate 340 is greater than that of the first circuit board 310, which is mainly used to provide structural support for the first circuit board 310, so as to avoid affecting the sealing communication effect of the microphone 320 and the sound pickup hole 110f due to structural deformation or damage of the first circuit board 310.

[0149] Exemplarily, the first circuit board 310 can adopt a flexible printed circuit (FPC), and the reinforcing plate 340 can be made of other materials (such as metal, plastic, etc.) with a material hardness greater than that of the first circuit board 310.

[0150] Therefore, by using the material characteristics of the flexible deformation of the first circuit board 310, the setting position of the control board assembly 200 in the shell assembly 100 can be adapted, and the electrical signal connection between the microphone assembly 300 and the control board assembly 200 can be realized; and the existence of the reinforcing plate 340 can effectively avoid affecting the sealing communication effect of the microphone 320 and the sound pickup hole 110f due to the structural deformation of the first circuit board 310.

[0151] In one embodiment, referring to FIG. 11, the protective screen 330 includes sequentially laminated fixed first adhesive layer 330a, gauze layer 330b and second adhesive layer 330c; wherein the first adhesive layer 330a and the second adhesive layer 330c can be double-sided adhesive tape or other suitable adhesive material according to actual needs, the second adhesive layer 330c can be used to laminate and fix the first circuit board 310 (or the reinforcing plate 340) and the gauze layer 330b as a whole, and the first adhesive layer 330a can be used to fix the microphone assembly 300 as a whole on the inner wall surface of the first shell 110b; thereby realizing the quick assembly of the microphone assembly 300 and the first shell 110b.

[0152] In other embodiments, the protective screen 330 can also adopt other structures, for example, the gauze layer 330 is fixed between the first circuit board 310 (or the reinforcing plate 340) and the inner wall of the first shell 110b in a manner of being pressed and clamped.

[0153] In one embodiment, referring to FIGS. 7, 9 and 10, the inner wall of the first shell 110 (for example, the surface of the fifth shell wall 110e) is provided with a second fixing structure, which can include a fixed baffle 151 protruding from the inner wall surface of the first shell 110, for example, the fixed baffle 151 is an integral structure with the first shell 110; a receiving groove is formed between the fixed baffle 151 and the inner wall surface of the fifth shell wall 110e; wherein at least part of the microphone assembly 300 (specifically, one end where the microphone 320 is located) is received and fixed in the receiving groove, and the sound outlet end of the sound pickup hole 110f is located within the contour range of the receiving groove.

[0154] On the one hand, by means of the receiving groove formed between the fixed baffle 151 and the inner wall surface of the first shell 110, the installation position of the microphone assembly 300 can be quickly positioned, thereby providing support for the structural combination of the microphone assembly 300 and the first shell 110; on the other hand, by means of the fixed baffle 151, the microphone assembly 300 can be limited to the inner preset position (i.e., in the receiving groove) of the accommodating cavity 100a, thereby ensuring that the sound inlet channel of the microphone 320 can maintain coaxial sealed communication with the sound pickup hole 110f.

[0155] In other embodiments, the second fixing structure can also adopt other suitable structural forms, for example, under the premise of ensuring the sealed communication of the microphone assembly 300 and the sound pickup hole 110f, the second fixing structure can be a buckle structure provided on the inner wall surface of the first shell 110, so as to clamp and fix the microphone assembly 300 at a position corresponding to the sound pickup hole 110f; or the second fixing structure is a sink structure provided on the inner wall surface of the third side wall, and at least part of the microphone assembly 300 is inserted into the space of the second fixing structure. All of the above will not be repeated here.

[0156] In one embodiment, referring to FIG. 8, for the convenience of description, the area where the fifth shell wall 110e is located within the contour of the receiving groove is defined as a bearing wall surface, which is arranged as a planar structure perpendicular to the geometric center line of the sound pickup hole 110f, and the microphone assembly 300 (for example, the first circuit board 310 or the combination of the first circuit board 310 and the reinforcing plate 340) is arranged in the receiving groove in a parallel manner to the bearing wall surface, and the protective net 340 is exemplarily laminated and fixed between the first circuit board 310 and the bearing wall surface.

[0157] The bearing wall surface can stably fix the part of the first circuit board 310 provided with the microphone 320 in the receiving groove, ensure the sound inlet channel of the microphone 320 to be coaxially communicated with the sound pickup hole 110f, and thus create conditions for enhancing the air tightness of the sound channel of the microphone 320.

[0158] In one embodiment, referring to FIG. 10, the fixed barrier wall 151 is provided with a first avoiding gap 152, which is mainly used for avoiding the structural part of the microphone assembly 300 for electrically connecting the control board assembly 200; the microphone assembly 300 can be exemplarily divided into two parts of a connecting part 300a and a sound pickup part 300b connected with each other; the sound pickup part 300b can be understood as the part of the first circuit board 310 provided with the microphone 320 and needing to be received in the receiving groove, and the connecting part 300a can be understood as the part of the first circuit board 310 leading out from the receiving groove and connecting the control board assembly 200; the sound pickup part 300b is equivalent to being arranged at one end of the connecting part 300a, and the sound pickup part 300b is inserted into the receiving groove in a manner of coaxially and sealingly communicating the sound inlet channel with the sound pickup hole 110f; and the end of the connecting part 300a away from the sound pickup part 300b can be extended out of the receiving groove to the space position of the control board assembly 200 by means of the first avoiding gap 152.

[0159] Based on the first avoiding gap 152, structural interference between the microphone assembly 300 and the fixed barrier wall 151 can be avoided, the structural connection of the microphone assembly 300, the first shell 110 and the control board assembly 200 is facilitated, and structural support for realizing the sealing communication between the sound inlet channel of the microphone assembly 300 and the sound pickup hole 110f is provided.

[0160] In one embodiment, referring to FIGS. 8 and 10, the receiving groove is provided with sealing glue, which can fill or seal the structural gap between the fixed barrier wall 151 (or the receiving groove) and the microphone assembly 300 (for example, the first circuit board 310, the reinforcing plate 340, etc.), effectively enhance the sealing communication effect of the sound inlet channel of the microphone assembly 300 and the sound pickup hole 110f, and stably fix the microphone assembly 300 to the first shell 110, so as to avoid the microphone assembly 300 from being separated from the first shell 110 due to the impact or falling of the wearable device.

[0161] In some embodiments, a groove structure can be arranged on the bearing wall and communicated with the receiving groove. The groove structure can receive the protective net 330, the reinforcing plate 340 and other components in the microphone assembly 300, so as to position the microphone assembly 300 and the sound pickup hole 110f, and increase the relative height of the fixed barrier wall 151 or the capacity of the receiving groove, thereby avoiding the influence of the installation and work of the button assembly 400, the control board assembly 200 and other components arranged adjacent to the microphone assembly 300 in the process of filling the sealant.

[0162] In one embodiment, referring to FIGS. 2, 3, 8-10 and 12, the movement core assembly further includes a control board assembly 200 arranged and electrically connected with the microphone assembly 300, for receiving the sound signals collected by the microphone assembly 300 and converting the sound signals into electrical signals and outputting the electrical signals to a speaker device. The microphone assembly 300 and the control board assembly 200 are arranged in the housing space of the first housing 100, and the microphone assembly 300 and the control board assembly 200 are respectively fixedly connected with the inner wall of the first housing 110 (for example, the fifth housing wall 110e).

[0163] For example, the number of microphone assemblies 300 is two, and the two microphone assemblies 300 are arranged at intervals on opposite sides of the control board assembly 200 and are respectively electrically connected with the control board assembly 200. For example, the control board assembly 200 is arranged between the two microphone assemblies 300 in the first direction. It can also be understood that the two microphone assemblies 300 are arranged at intervals inside the housing assembly 100, and the control board assembly 200 is located between the two microphone assemblies 300 in the arrangement direction of the two microphone assemblies 300.

[0164] Therefore, by fixing the control board assembly 200 and the microphone assembly 300 to the inner wall of the first housing 110 respectively, and using the first housing 110 as the mounting carrier of the two, the structural integration of the control board assembly 200, the microphone assembly 300 and the housing assembly 100 can be further realized, the number of related connecting components can be reduced, and the structure and space of the housing assembly 100 can be further fully utilized. In addition, the opening of the first housing 110 can provide support for the microphone assembly 300 and the control board assembly 200 to enter and exit the interior of the first housing 110 when the microphone assembly 300 and the control board assembly 200 are disassembled and maintained.

[0165] In one embodiment, referring to FIGS. 8-12, the control board assembly 200 includes a second circuit board 210, which is made of a material having a rigidity greater than that of the first circuit board 310. For example, the first circuit board 310 can be a flexible printed circuit board (FPC), and the second circuit board 210 can be a rigid printed circuit board (PCB).

[0166] For ease of description, the opposite ends of the first circuit board 310 in its length direction (or first direction) are defined as a first end and a second end. The microphone 320, the reinforcing plate 340, and the protective mesh 330 are arranged at the first end of the first circuit board 310, which can also be understood as corresponding to the sound pickup portion 300b of the microphone assembly 300 or the end of the sound pickup portion 300b away from the connecting portion 300a. The second end of the first circuit board 310 is fixedly connected (e.g., welded) to the second circuit board 210, which can also be understood as corresponding to the connecting portion 300a of the microphone assembly 300 or the end of the connecting portion 300a away from the sound pickup portion 300b.

[0167] On the one hand, based on the structure of the soft board combined with the hard board formed between the microphone assembly 300 and the control board assembly 200. Firstly, the structure connection between the microphone assembly 300 and the control board assembly 200 can be made more compact, saving the structural space of the accommodating cavity 100a. Secondly, based on the flexible deformation characteristics of the first circuit board 310 compared to the second circuit board 210, the structure of the internal space of the shell assembly 100 (e.g., the inner surface side of the first shell 110) can be adapted, and the relative installation position between the microphone assembly 300 and the control board assembly 200 can be flexibly adjusted, such as directly mounting and fixing the microphone assembly 300 on the first shell 110. Thirdly, the microphone assembly 300 and the control board assembly 200 can be easily disassembled to realize recycling of important electronic components, such as control chips in the control board assembly 200.

[0168] On the other hand, in some embodiments of the shell assembly 100 using a profiled structure, since the third side wall (i.e., the fifth shell wall 110e) adopts an arc surface structure, the control board assembly 200 and the microphone assembly 300 have different orientations or different height differences relative to the inner surface of the third side wall. The connection between the two in the form of a soft board combined with a hard board can well adapt to the differences in installation position and installation form between the control board assembly 200 and the microphone assembly 300, facilitating quick and accurate installation and fixation of the control board assembly 200 and the microphone assembly 300.

[0169] In one embodiment, referring to FIG. 9, the first circuit board 310 has one or more bending regions 310b, which can be preformed between the first end and the second end of the first circuit board 310 (e.g., the portion of the first circuit board 310 extending out of the receiving slot through the first avoiding gap 152) or naturally formed during the assembly of the microphone assembly 300, the control board assembly 200, and the shell assembly 100.

[0170] In other words, based on the material characteristics of the first circuit board 310, which can be flexibly deformed, the length of the first circuit board 310 can be appropriately increased to have a certain length surplus according to the relative positions of the control board assembly 200 and the microphone assembly 300 on the first shell 110, and the bending regions 310b can be formed to adjust the path of the first circuit board 310 during the assembly process.

[0171] In this way, the precision requirement of the structural connection between the control board assembly 200 and the microphone assembly 300 can be reduced, thereby reducing the assembly difficulty, and the installation space can be saved to facilitate the adjustment of the relative positions of the microphone assembly 300 and the control board assembly 200.

[0172] In one embodiment, referring to FIGS. 2-4 and 8-12, the core assembly further includes a key assembly 400, which is mainly used to cooperate with the control board assembly 200 to input a preset instruction. The key assembly 400 is arranged inside the shell assembly 100 and movably connected to the inner wall of the shell assembly 100 in a form of at least partially exposed to the outside of the shell assembly 100. For example, the fifth shell wall 110e of the first shell 110 is provided with a key window 110g through which at least part of the key assembly 400 protrudes out of the first shell 110, and the key assembly 400 is rotatably connected to the inner wall (e.g., the third shell wall 110c and the fourth shell wall 110d) of the first shell 110. The inner wall (e.g., the fifth shell wall 110e) of the first shell 110 is provided with a third fixing structure, which is mainly used to support and fix the control board assembly 200 (e.g., the second circuit board 210) at a preset position in the receiving cavity 100a, so that the control board assembly 200 and the microphone assembly 300, and the control board assembly 200 and the first shell wall 110e maintain a sufficient interval distance.

[0173] Exemplarily, referring to FIG. 7 and FIG. 10, the third fixing structure can include a plurality of support columns 161 protruding from the fifth shell wall 110e, and the plurality of support columns 161 are arranged at intervals around the geometric center line of the second circuit board 210; correspondingly, the second circuit board 210 is provided with a positioning through hole 210a corresponding to the positions of the support columns 161; the support columns 161 are inserted into the positioning through hole 210a, so that the second circuit board 210 or the control board assembly 200 can be supported and fixed on the first shell 110 in a manner of being spaced from the inner surface of the fifth shell wall 110e.

[0174] On the one hand, by means of the cooperation of the support columns 161 and the positioning through hole 210a, a fixed interval distance can be formed between the control board assembly 200 and the microphone assembly 300, so as to avoid signal interference therebetween.

[0175] On the other hand, based on the support columns 161, a certain structural gap can be formed between the second circuit board 210 and the inner wall of the first shell 110, so as to provide a structural space for assembling the key assembly 400 to the first shell 110; for example, the second circuit board 210 can be arranged transversely in the accommodating cavity 100a along the third direction (or the width direction of the device main body) (it can also be understood that the plane where the second circuit board 210 is located is substantially perpendicular to the third shell wall 110c and the fourth shell wall 110d), so as to utilize the structural gap between the second circuit board 210 and the fifth shell wall 110e as a structural mounting space and a moving space of the key assembly 400. In this way, it is convenient to control the overall width and thickness dimensions of the device main body, and it is also convenient to fix and assemble the microphone assembly 300 and the control board assembly 200 to the first shell 110 in steps.

[0176] In other embodiments, the third fixing structure can also adopt other suitable structural forms, for example, the support columns 161 protrude from the second circuit board 210, and a slot structure is arranged on the inner wall surface of the first shell 110 for inserting and fixing the support columns 161; details are not described herein.

[0177] In one embodiment, referring to FIG. 4 to FIG. 6, and combining with FIG. 10 and FIG. 12, a first limiting structure is further arranged between the first shell 110 and the second shell 120; on the one hand, the first limiting structure can limit the relative position between the first shell 110 and the second shell 120, and enhance the structural connection strength between the first shell 110 and the second shell 120; on the other hand, the first limiting structure can prevent the first shell 110 and the second shell 120 from being deformed at the joint therebetween, so as to avoid the control board assembly 200 (specifically, the second circuit board 210) being pressed due to the structural deformation of the shell.

[0178] For example, referring to FIGS. 4-6, the first shell 110 and the second shell 120 are both in a shell structure, and the surface of the first shell 110 and the second shell 120 that abuts against each other in the second direction is defined as the joint surface; wherein the joint surface of the first shell 110 is provided with a first limiting flange 171 that protrudes toward the side of the second shell 120 along the second direction, and the joint surface of the second shell 120 is provided with a second limiting flange 172 that protrudes toward the side of the first shell 110 along the second direction.

[0179] In the assembled state of the shell assembly 100, the first limiting flange 171 is located on the side of the second limiting flange 172 that faces away from the accommodating cavity 100a in the third direction (i.e., with the accommodating cavity 100a as a reference, the first limiting flange 171 is located outside the accommodating cavity 100a), which can also be understood as, in the inner-outer direction of the shell assembly 100, the second limiting flange 172 is located on the inner side of the first limiting flange 171.

[0180] By means of the second limiting flange 172 abutting against the first limiting flange 171 from the inner side of the accommodating cavity 100a, a first limiting structure is formed, which can avoid the shrinkage deformation of the first shell 110 at the opening due to the performance of the material itself, thereby preventing the first shell 110 from extruding the control board assembly 200 (specifically, the second circuit board 210); at the same time, it can also enhance the structural connection strength of the first shell 110 and the second shell 120 at the joint surface, reduce or eliminate the structural gap between the first shell 110 and the second shell 120, and ensure the integrity of the overall profile of the shell assembly 100.

[0181] In some embodiments, the first limiting structure can also be arranged between the joint surfaces of the first shell 110 and the second shell 120 in other structural forms, for example, a flange is arranged on the joint surface of the second shell 120, and a slot is arranged on the joint surface of the first shell 110 corresponding to the position of the flange, and the flange is inserted into the slot to form the first limiting structure, thereby also preventing the first shell 110 from deforming in the third direction, thereby achieving the purpose of preventing the first shell 110 from extruding the first assembly (such as the control board assembly 200).

[0182] In some embodiments, the first limiting structure can include a flange and a slot, and the flange and the slot are arranged on the joint surfaces of the first shell 110 and the second shell 120; by means of the one-to-one corresponding structure relationship between the flange and the slot, the first shell 110 and the second shell 120 can be prevented from deforming in the third direction, thereby achieving the effect of protecting the control board assembly 200 from being extruded by the shell.

[0183] In one embodiment, referring to FIGS. 4-6, the first limiting structure is provided in multiple groups, and the multiple groups of the first limiting structure are arranged on opposite sides of the accommodating cavity 100a in the third direction, for example, on opposite sides of the second circuit board 210 in the third direction. In this way, the first shell 110 can be further prevented from deforming, and the stability of the structural connection between the first shell 110 and the second shell 120 can be improved.

[0184] Of course, the first limiting structure can also be arranged at intervals in the second direction to limit the deformation of the shell from the third direction, the first direction, and other directions, so as to ensure that the joint surfaces of the first shell 110 and the second shell 120 can stably abut each other.

[0185] In one embodiment, referring to FIGS. 4-6, the first limiting structure further includes an avoiding structure, which is mainly used to avoid part of the first assembly or the second assembly (for example, the control board assembly 200) during the assembly of the first shell 110 and the second shell 120, so as to adapt to the space size requirement of the first assembly or the second assembly to the accommodating cavity 100a. For example, the first limiting flange 171 is located on the side of the second limiting flange 172 that faces away from the accommodating cavity 100a in the third direction. The avoiding structure can be a notch provided on the second limiting flange 172. For the purpose of distinguishing and describing, the notch is defined as a second avoiding notch 173.

[0186] During the assembly of the first shell 110 and the second shell 120, the second avoiding notch 173 can be used to adapt the second shell 120 to the contour size of the second circuit board 210, so as to avoid or accommodate the part of the second circuit board 210 that protrudes outward of the shell assembly 100 in the third direction. In this way, the joint surfaces of the first shell 110 and the second shell 120 and the first limiting flange 171 and the second limiting flange 172 can be effectively abutted, and the structural extrusion or structural interference on the control board assembly 200 can be avoided.

[0187] In other embodiments, the avoiding structure can also be a groove structure provided on the surface of the second limiting flange 172 that faces the accommodating cavity 100a, or a structural gap between two adjacent second limiting flanges 172 in the first direction.

[0188] The above application of specific examples is used to illustrate the present application, which is only used to help understand the present application and does not limit the present application. According to the idea of the present application, those skilled in the art can make some simple deductions, modifications, or substitutions.
