This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0064] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0065] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" in this application, unless otherwise specified, include both direct and indirect connections (couplings).

[0066] This article mainly takes the in-ear hearing aid as an example to describe the wearable device provided in the embodiments of the present application; 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, headphones, glasses and other devices.

[0067] Please refer to FIG1 , the wearable device includes a housing assembly 100 , a movement assembly, a speaker device, and other functional components as needed.

[0068] The core component can be understood as a collection of related components that realize the main functions of the wearable device. For example, the core component can support the collection of sound signals, conversion and processing of electrical signals, powering on and off the device, volume adjustment, power supply and other functions; the core component is arranged in the shell component 100, so as to be combined with the shell component 100 to form a complete functional structure; for the convenience of distinction and description, the combined structure of the shell component 100 and the core component is defined as the device body.

[0069] The speaker device can be understood as a collection of components that enable the wearable device to play sound signals. In some embodiments, the speaker device is arranged in connection with the device body, i.e. the speaker device is arranged externally to the housing assembly 100.

[0070] By way of example, referring to Fig. 1, the speaker device is an in-ear speaker, which includes a speaker assembly 810 and a wearing assembly 820. The speaker assembly 810 is arranged in a form that can be adaptively inserted into the ear canal of a user, and mainly serves to play sound signals to the user. The wearing assembly 820 is arranged between the speaker assembly 810 and the housing assembly 100 in a form of electrically connecting the speaker assembly 810 and the core assembly, and mainly serves to establish a signal connection relationship between the core assembly and the speaker assembly 810.

[0071] The wearing assembly 820 can be a flexible cable having a signal transmission function, or other wires having both a signal transmission function and a shape memory function. One end of the wearing assembly 820 is fixed and electrically connected to the speaker assembly 810, and the other end of the wearing assembly 820 can be connected to the housing assembly 100 in a detachable or non-detachable manner and electrically connected to the core assembly.

[0072] The wearing assembly 820 can also be used to stably wear the device body on the ear of the user, and to insert the speaker assembly 810 into the ear canal of the user. The device body (specifically, the core assembly) can collect external sound signals, and by converting the sound signals into electrical signals and outputting them to the speaker assembly 810, the corresponding sound signals can be played by the speaker assembly 810 to achieve the hearing aid function of the wearable device.

[0073] In other embodiments, the speaker device can also be arranged in other forms in the wearable device, for example, the core assembly is arranged directly inside or outside the housing 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.

[0074] It can be understood that, in the wearable device in the powered state, through the cooperation of the core assembly and the speaker device, the conversion between the sound signal (for example, the mechanical vibration signal) and the electrical signal can be realized, so that the user can hear the sound through the ear. Generally speaking, the mechanical vibration can act on the eardrum of the user through air as a medium based on the principle of air conduction, and then act on the auditory nerve; the mechanical vibration can also directly act on the auditory nerve of the user through the bone and tissue of the user as a medium based on the principle of bone conduction; for the sound heard by the user, the former can be called "air conduction sound", and the latter can be simply called "bone conduction sound".

[0075] Based on this, through the selection and configuration of the specific functional structure of the core assembly and the speaker device, the wearable device can form air conduction sound, bone conduction sound, and simultaneously realize air conduction sound and bone conduction sound.

[0076] In order to more clearly and specifically describe the structure of the device body, based on the outer contour shape 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".

[0077] 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.

[0078] Exemplarily, in the state that 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.

[0079] In one embodiment, referring to FIGS. 1-7, the shell assembly 100 includes a first shell 110 and a second shell 120; the first shell 110 and the second shell 120 are connected to each other in a cooperative manner to enclose a receiving cavity 100a in the interior of the shell assembly 100 (or between the first shell 110 and the second shell 120); the core assembly is arranged in the receiving cavity 100a; wherein at least a part of the core assembly 100 is connected and arranged on the first shell 110, and at least another part of the core assembly 100 is connected and arranged on the second shell 120.

[0080] Exemplarily, 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; for the convenience of distinguishing and describing, the functional components in the core assembly connected with the first shell 110 are defined as the first assembly, and the functional components in the core assembly connected with the second shell 120 are defined as the second assembly. Among them, the first assembly can include the control board assembly 200, the microphone assembly 300, and the button assembly 400; the second assembly can include the first interface assembly 500, the second interface assembly 600, and the battery assembly 700.

[0081] The microphone assembly 300 is electrically connected with the control board assembly 200 and is fixed to the first shell 110; the microphone assembly 300 is mainly used to collect the sound signals outside the device (specifically, outside the shell assembly 100), for example, the mechanical vibration of the related components of the microphone assembly 300 itself caused by the external environmental sound, so that the microphone assembly 300 realizes the collection of the sound signals.

[0082] 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 the loudspeaker device (specifically, the loudspeaker assembly 810), so as to play the sound signals to the user by means of the loudspeaker device.

[0083] The button assembly 400 is movably connected to the first shell 110 and is arranged in cooperation with the control board assembly 200; through the cooperation of the button assembly 400 and the control board assembly 200, the input of the preset instruction can be realized; for example, the button assembly 400 can input the instruction of controlling the wearable device to start and shut down, the instruction of adjusting the volume, or other instructions to the control board assembly 200.

[0084] The first interface assembly 500, the second interface assembly 600, and the battery assembly 700 are connected to the second shell 120 and are electrically connected with the control board assembly 200; for example, an electrical signal connection relationship is established with the control board assembly 200 through a wire assembly. Among them, the first interface assembly 500 mainly plays a role of connecting the loudspeaker device in the device main body, for example, in a plug-in form, the first interface assembly 500 is detachably connected with the wearing assembly 820, so as to establish a signal connection relationship between the loudspeaker assembly 810 and the control board assembly 200, so that the loudspeaker assembly 810 can produce or play the sound signals due to the electrical signals provided by the control board assembly 200.

[0085] The second interface assembly 500 is mainly used for connecting external control devices (such as mobile phones, computers, etc.) to transmit data between the external control devices and the wearable device; for example, the working mode, working parameters, volume size, etc. of the wearable device can be adaptively adjusted according to the user's needs through the external control device. The battery assembly 700 is mainly used for powering the power components in the wearable device to provide support for the normal operation of the wearable device.

[0086] In some embodiments, other functional components can also be added or some functional components 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 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.

[0087] 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.

[0088] In some embodiments, based on the structure form inside the shell assembly 100, the functional components in the first assembly and the second assembly can also be arranged in each other, for example, the first interface assembly 500 belongs to the first assembly and is connected to the first shell 110.

[0089] That is, 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, etc. can be selectively connected to the first shell 110 or the second shell 120 according to the structure layout and functional configuration of the shell assembly 100 or the device main body.

[0090] 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 circuit board (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 components, so as to flexibly establish the electrical connection relationship between the related functional components.

[0091] Based on this, by taking the first shell 110 and the second shell 120 as the installation carrier of the plurality of functional components inside the device, the movement core assembly can be dispersedly arranged at different parts of the shell assembly 100.

[0092] In one aspect, compared with the related art in which an internal skeleton independent of the shell assembly 100 is used as a mounting carrier of the movement assembly, the present application can achieve full utilization of the shell structure and space, reduce the number of internal components of the device, and thus facilitate miniaturization and lightweight design of the wearable device.

[0093] On the other hand, based on the structure in which the movement assembly is dispersedly arranged, not only can the wearable device be quickly disassembled and assembled, but also through disassembly of the first shell 110 and the second shell 120, the first assembly and the second assembly can be disassembled, maintained, recycled, and reused.

[0094] In one embodiment, referring to FIGS. 4 to 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 a form in which the openings face each other in the second direction to enclose the accommodation cavity 100a.

[0095] As for the movement assembly, the first assembly (for example, the control board assembly 200, the microphone assembly 300, the key assembly 400, etc.) is connected to 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; and the second assembly (for example, the first interface assembly 500, the second interface assembly 600, the battery assembly 700, etc.) is connected to 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.

[0096] Firstly, by connecting the first assembly to the inner wall of the first shell 110 and connecting the second assembly to the inner wall of the second shell 110, the connection structure between the movement assembly and the shell assembly 100 can be prevented from being exposed to the shell assembly 100 and affecting the appearance profile of the device main body, thereby improving the appearance aesthetics and wearability of the device main body.

[0097] Secondly, by accommodating the first assembly and the second assembly in the shell space of the first shell 110 and the second shell 120, a certain protection effect can be achieved to prevent the first assembly or the second assembly from being damaged due to bumping before the shell assembly 100 is assembled.

[0098] Thirdly, by setting the first shell 110 and the second shell 120 as shell structures with a certain volume space inside and with an opening, the first shell 110 and the first assembly, and the second shell 120 and the second assembly 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.

[0099] In some embodiments, the first shell 110 can adopt a shell structure with an opening, and the second shell 120 can adopt a cover structure; the second shell 120 is arranged on the first shell 110 in a manner of covering the opening of the first shell 110 to form the accommodation cavity 100a together with the first shell 110; as for the movement core assembly, the first assembly is connected and arranged on the inner wall of the first shell 110 and is accommodated in the shell space of the first shell 110; the second assembly is connected and arranged on the side of the second shell 120 facing the first shell 110; after the first shell 110 and the second shell 120 are combined, the second assembly is equivalent to being accommodated in the shell space (i.e., the accommodation cavity 100a) of the first shell 110. Of course, the first shell 110 can adopt a cover structure, and the second shell 120 can adopt a shell structure with an opening.

[0100] In this way, the shell assembly 100 is combined in the form of a shell structure cooperating with a cover structure, which not only facilitates the rapid assembly of the device main body, but also can form wearable devices of different structural forms or assembly modes to meet different application requirements.

[0101] In one embodiment, referring to FIGS. 4-7, an assembly structure is arranged between the first shell 110 and the second shell 120, which is mainly used to assemble and fix the first shell 110 provided with the first assembly and the second shell 120 provided with the second assembly into one, so as to form the complete outer contour structure (i.e., the shell assembly 100) of the device main body, thereby enabling the wearable device or the device main body to be moved, carried, worn, operated and used by means of the shell assembly 100.

[0102] 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 forms such as gluing and welding 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 forms such as clamping and locking between the first shell 110 and the second shell 120.

[0103] 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 to stably fix the first shell 110 and the second shell 120 into one; the first positioning structure is mainly used to position the relative positions between the first shell 110 and the second shell 120 to provide support for quickly and accurately assembling the first shell 110 and the second shell 120, and to enhance the structural combination strength of the first shell 110 and the second shell 120 in cooperation with the first fixing structure.

[0104] The first fixing structure comprises a support arm 131 and a fixing pin 132; the support arm 131 protrudes from the inner wall of the second shell 120, for example, the support arm 131 is in an integrated structure with the second shell 120; the fixing pin 132 cooperates with the support arm 131.

[0105] The first positioning structure comprises a first positioning protrusion 141 and a first positioning slot hole 142; the first positioning protrusion 141 protrudes from the inner wall of the first shell 110, and the first positioning protrusion 141 is in an integrated 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.

[0106] 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 inserted into the first positioning slot hole 142 in advance by virtue of the alignment relationship between the first positioning protrusion 141 and the first positioning slot hole 142, so as to limit the relative position of the first shell 110 and the second shell 120, for example, the open end faces of the first shell 110 and the second shell 120 abut each other, so that the first space and the second space are in communication to form the accommodation cavity 100a (at this time, the support arm 131 is located in the accommodation cavity 100a).

[0107] 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 arranged at the position of the first shell 110 corresponding to the support arm 131), so as to integrally fix the first shell 110 and the support arm 131, thereby finally achieving the detachable assembly and fixing between the first shell 110 and the second shell 120.

[0108] 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 protrudes from the inner wall of the first shell 110, and the first positioning protrusion 141 protrudes from the inner wall of the second shell 120.

[0109] By virtue 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, quickly and accurately achieved, so as to effectively enhance the structural stability of the shell assembly 100 (or the device shell), and provide structural support for the detachable assembly of the device main body or the shell assembly 100.

[0110] For example, during the assembly of the device main body or the shell assembly 100, the first positioning protrusion 141 can be first inserted into the corresponding first positioning slot 142, and then the fixed pin 132 is inserted into the shell assembly 100 by using the cooperation of the support arm 131 and the fixed 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.

[0111] For example, when the device main body needs to be disassembled for maintenance, the fixed pin 132 can be pulled out to disassemble the shell assembly 100, so as to check and maintain the structure and related components inside the device main body.

[0112] In some embodiments, the first fixing structure and the first positioning structure can also adopt other structural forms.

[0113] For example, a plurality of buckle structures are arranged on the first shell 110 and the second shell 120 to replace the first fixing structure and the first positioning structure, so as to assemble and fix the first shell 110 and the second shell 120.

[0114] For another example, a protruding 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 protruding shaft structure to be inserted, so as to form the first fixing structure by the cooperation of the protruding shaft structure and the pin hole structure, thereby positioning and fixing the first shell 110 and the second shell 120 from different positions and different directions under the cooperation of the first positioning structure.

[0115] 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 gluing, welding or the like.

[0116] Of course, the first positioning structure can also be omitted, and a plurality of groups of support arms 131 and fixed pins 132 are arranged to fixedly connect the first shell 110 and the second shell 120 from a plurality of different positions. All these will not be repeated here.

[0117] In one embodiment, referring to FIGS. 4 and 5, the first shell 110 and the second shell 120 are connected to each other in the second direction to form the shell assembly 100, and the first fixing structure and the first positioning structure are arranged at two opposite ends of the shell assembly 100 in the first direction. For ease of description, the two opposite ends of the shell assembly 100 in the first direction or the length direction can be defined as the first end and the second end of the shell assembly 100. When the wearable device is in a normal wearing state, the first end of the shell assembly 100 can be the upper end of the shell assembly 100, and the second end of the shell assembly 100 can be the bottom end of the shell assembly 100. The first fixing structure is arranged at the first end of the shell assembly 100, and the first positioning structure is arranged at the second end of the shell assembly 100.

[0118] By arranging the first fixing structure and the first positioning structure at the two opposite ends of the shell assembly 100, the first shell 110 and the second shell 120 can be positioned and combined by means of the first positioning structure in advance during assembly, and then the first shell 110 and the second shell 120 can be fixed by using the cooperation 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 shell 110 and the second shell 120, thereby improving the assembly efficiency of the shell 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 shell assembly 100 by disassembling the shell assembly 100.

[0119] In some embodiments, the control board assembly 200, the microphone assembly 300, etc. are connected to the inner wall of the first shell 110, the first interface assembly 500, the battery assembly 700, etc. are connected to the inner wall of the second shell 120, and the first shell 110 and the second shell 120 both adopt a shell structure. The support arm 131 is arranged on the side of the first shell 110 and protrudes from the inner wall of the second shell 120 in the second direction. The fixing pin 132 is arranged in the first shell 110 and the support arm 131 in the third direction. Correspondingly, the first positioning protrusion 141 is arranged on the side of the second shell 120 and protrudes from the inner wall or the opening end face of the second shell 120 in the second direction.

[0120] 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 shell 120 and the second assembly can be regarded as a mounting body, which guides the assembly personnel to quickly and accurately assemble the combination of the first shell 110 and the first assembly to the mounting body.

[0121] In one embodiment, referring to FIG. 2 and FIG. 3, 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.

[0122] 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 the first shell wall 110a and the second shell wall 110b, the two shell walls opposite to each other in the third direction are defined as the third shell wall 110c and the 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 the fifth shell wall 110e.

[0123] The two shell walls of the second shell 120 opposite to each other in the first direction are defined as the sixth shell wall 120a and the seventh shell wall 120b, the two shell walls opposite to each other in the third direction are defined as the eighth shell wall 120c and the 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 the tenth shell wall 120e.

[0124] Among them, the first shell wall 110a and the sixth shell wall 120a combine to form the first side wall of the shell assembly 100, the second shell wall 110b and the seventh shell wall 120b combine to form the second side wall of the shell assembly 100, the fifth shell wall 110e and the tenth shell wall 120e can be understood as the third side wall and the fourth side wall of the shell assembly 100 opposite to each other in the second direction, the third shell wall 110c and the eighth shell wall 120c combine to form the fifth side wall of the shell assembly 100, and the fourth shell wall 110d and the ninth shell wall 120d combine to form the 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 the accommodation cavity 100a.

[0125] Referring to FIG. 2, the control board assembly 200 is arranged inside the shell assembly 100, for example, fixedly connected with 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.

[0126] 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, so that external sound signals are 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.

[0127] 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.

[0128] 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.

[0129] 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 to the third side wall.

[0130] 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 from the third side wall through the key window 110g.

[0131] 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.

[0132] 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.

[0133] Referring to FIGS. 2 and 6, the first interface assembly 500 is arranged in the accommodating cavity 100a in a form of being at least partially exposed to the first side wall, and is 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.

[0134] 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).

[0135] Please refer to FIG. 2 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 in correspondence with 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.

[0136] Please refer to FIG. 2 to 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 and the fourth side wall meet, and the battery assembly 700 is movably connected to the second shell 120, so that the battery assembly 700 can be taken in and out of the accommodating cavity 100a through the battery window 120h by rotating the battery assembly 700, so as to replace the battery.

[0137] 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.

[0138] For example, by arranging the first interface assembly 500 and the battery assembly 700 at opposite ends of the device main body along the first direction, the key assembly 400 is arranged along the first direction at a 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) through 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 can be conveniently operated, and the structure interference of the first interface assembly 500 and the battery assembly 700 to the key assembly 400 can be avoided.

[0139] For example, by arranging two microphone assemblies 300 on two sides of the key assembly 400 or the control panel assembly 200 opposite to each other in the first direction, the arc-shaped structure of the third side wall can be used to make the sound pickup holes 110f corresponding to the two microphone assemblies 300 face different directions, so that the external sound signals can not be blocked by the user's body parts, and the sound signal collection effect of the microphone assemblies 300 can be ensured.

[0140] 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 relying on the wearing assembly 820, and the speaker assembly 810 is inserted into the user's ear canal:

[0141] The first side wall is the side wall facing the front side of the user in the first direction, the second side wall is the side wall facing the lower side of the user's ear in the first direction, the third side wall is the 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 the 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 the side wall facing or contacting the back side of the user's ear in the third direction, and the sixth side wall is the side wall facing or contacting the user's head in the third direction.

[0142] 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 direction and the third direction; the third side wall and the fourth side wall are arranged in an arc-shaped structure 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 arranged in an arc segment.

[0143] In this way, based on the size difference of the shell assembly 100 in different directions and the structure of the side walls, the outer contour of the shell assembly 100 or the device body is constructed in a profiled 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.

[0144] In the embodiment in which the shell assembly 100 adopts a profiled structure, the size of the shell assembly 100 in the third direction can be arranged 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 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 of the end where the battery assembly 500 is located, which can adapt to the space requirement of the battery assembly 500 on the shell assembly 100.

[0145] 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 integrated structure of polyimide material, and are connected and combined with each other to form the shell assembly 100.

[0146] Compared with the related art, the wearable device body shell is made of polycarbonate (PC) material, ABS plastic (i.e., a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S)) and other materials; in the 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 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.

[0147] As described above, the wearable device or device body can include a battery assembly 700, which is arranged in the accommodation cavity 100a in the form of directly connecting the shell assembly 100. In the following, the battery assembly 700 and its related structure will be described mainly by taking the example of the battery assembly 700 being connected and arranged on the second shell 120; however, it should be noted that the battery assembly 700 can also be connected and arranged on the first shell 110 or other suitable structure form of the device shell.

[0148] In one embodiment, referring to FIGS. 2-6 and 8-14, the second shell 120 is provided with a battery window 120h arranged through the seventh shell wall 120b and the tenth shell wall 120e, and the battery window 120h communicates the accommodation cavity 100a with the outside of the shell assembly 100; in terms of the shell assembly 100, the battery window 120h can be a strip-shaped window arranged through the second side wall and the fourth side wall 100c; therefore, in some embodiments, the width direction of the battery window 120h can be understood as the third direction of the shell assembly 100, and the length direction of the battery window 120h can be understood as the direction around the third direction of the shell assembly 100.

[0149] The battery assembly 700 comprises a battery holder 710 for accommodating the battery 730 and an electrode spring 720 for electrically connecting the control board assembly 200. The battery holder 710 and the second shell 120 form a second rotating shaft structure and a locking structure. The second rotating shaft structure is used to establish a relatively rotatable structural connection between the battery holder 710 and the second shell 120, so that the battery holder 710 can rotate relative to the second shell 120 about the second rotating shaft structure (the direction of the rotating shaft of the second rotating shaft structure or the battery holder 710 is the third direction), so that the battery holder 710 can enter and exit the accommodating cavity 100a through the battery window 120h. The locking structure is used to lock the battery holder 710 to the second shell 120 (for example, so that the battery holder 710 remains in the accommodating cavity 100a), that is, the locking structure can lock the battery holder 710 to the second shell 120 when the battery holder 710 closes the battery window 120h.

[0150] The electrode spring 720 is arranged in the accommodating cavity 100a and fixedly connected to the second shell 120. For example, the number of electrode springs 720 is two, and the two electrode springs 720 are arranged on the two sides of the battery window 120h in the third direction. When the battery holder 710 is locked to the second shell 120 by the locking structure, so that the battery 730 accommodated on the battery holder 710 is located in the accommodating cavity 100a, one end of each of the two electrode springs 720 can elastically abut the positive and negative electrodes of the battery 730, and the other end of each of the two electrode springs 720 can be electrically connected to the control board assembly 200 through the wire assembly.

[0151] On the one hand, the second shell 120 is used as a mounting carrier of the battery assembly 700, and by dispersively arranging the components of the battery assembly 700 (i.e., the battery holder 710 and the electrode spring 720) in the second shell 120, the structural space of the second shell 120 or the shell assembly 100 can be fully utilized, which is beneficial to the lightweight and miniaturized design of the wearable device.

[0152] On the other hand, by using the structure that the battery holder 710 can rotate out of the shell assembly 100 through the battery window 120h, the battery 730 can be conveniently replaced. After the battery holder 710 is rotated into the accommodating cavity 100a, the structure of the battery window 120h can be adapted to realize the closure of the battery window 120h, so as to maintain the integrity of the outer contour structure of the device main body.

[0153] It should be noted that the description of the battery 730 is introduced in this embodiment only for the purpose of understanding the structural configuration and functional principle of the battery holder 710, and does not mean that the battery 730 is necessarily a component of the battery assembly 700. That is, in some embodiments, the battery 730 can be a component of the battery assembly 700; in other embodiments, the battery 730 can also be a consumable used with the wearable device.

[0154] In one embodiment, referring to FIGS. 8-12, the battery holder 710 has a peripheral wall portion 711 and an end wall portion 712 arranged in contact with each other; the peripheral wall portion 711 extends around the geometric center line of the end wall portion 712 or is arranged in a closed manner to form a battery compartment for accommodating the battery 730 between the peripheral wall portion 711 and the end wall portion 712; it can also be understood that the overall profile of the battery holder 710 is generally a single-end open cylindrical structure; for example, the battery compartment can accommodate a button cell, and the end wall portion 712 and the open end of the battery compartment are respectively opposite the negative and positive poles of the battery 730.

[0155] The second rotation shaft structure and the locking structure are arranged outside the battery compartment; the second rotation shaft structure can be formed between the second housing 120 and the peripheral wall portion 711, and the axis line of the second rotation shaft structure (or the rotation axis line of the battery holder 710) is parallel to the geometric center line of the battery compartment; the locking structure can be formed between the second housing 120 and the peripheral wall portion 711 or the end wall portion 712;

[0156] In terms of the relative position relationship between the second rotation shaft structure, the locking structure, and the battery window 120h, the second rotation shaft structure and the locking structure are arranged on opposite sides of the battery window 120h in the length direction thereof; from the perspective of the device main body, the locking structure can be located at the bottom end of the device main body or the housing assembly 100 in the up-down direction of the user.

[0157] Therefore, the battery holder 710 can be conveniently and quickly unlocked and rotated for control at one end where the locking structure is located (for example, the bottom end of the device main body), improving the operation experience; at the same time, in some embodiments in which the housing assembly 100 adopts a profiled structure, since the battery window 120h is equivalent to a strip-shaped window arranged through the second side wall and the fourth side wall of the housing assembly 100, the length trajectory of the battery window 120h is generally an arc segment; therefore, the peripheral wall portion 711 can well adapt to the arc shape of the battery window 120h, and the battery window 120h is closed by the peripheral wall portion 711, thereby ensuring the integrity of the outer profile structure of the device main body.

[0158] In other embodiments, the battery holder 710 can also adopt other structural forms, for example, the battery holder 710 can be provided in a cover plate structure substantially identical to or matching the structural form of the battery window 120h, and the battery 730 is detachably arranged on the second housing 120 and located in the accommodating cavity 100a. The battery window 120h can be opened or closed by the battery holder 710, and after the battery window 120h is opened, the battery 730 in the accommodating cavity 100a can be removed to replace the battery 730. Of course, the electrode spring 720 can also adopt other suitable structural components.

[0159] In one embodiment, referring to FIGS. 8 and 11 in combination with FIG. 2, the locking structure includes a locking protrusion 187 and a locking slot 713. The locking protrusion 187 is arranged to protrude from the inner wall surface (for example, the seventh housing wall 110b) of the second housing 120 near the battery window 120h. The locking slot 713 is arranged at the position where the peripheral wall portion 711 or the end wall portion 712 connects with the peripheral wall portion 712.

[0160] When the battery holder 710 is rotated to the preset angular position in the accommodating cavity 100a through the battery window 120h, the locking protrusion 187 can be clamped in the locking slot 713, thereby limiting the continuous rotation of the battery holder 710 and achieving the locking of the battery holder 710 on the second housing 120.

[0161] In some embodiments, the battery holder 710 and the housing assembly 100 can be made of plastic materials, for example, the battery holder 710 is made of a one-piece structure of polyimide material, and the second housing 120 is made of a one-piece structure of polyimide material.

[0162] On the one hand, the locking protrusion 187 formed on the second housing 120 can be clamped in the locking slot 713 in an interference form, so as to rely on the material property that the battery holder 710 or the second housing 120 itself can be elastically deformed, to stably lock the battery holder 710 on the second housing 120. On the other hand, the battery holder 710 and the housing assembly 100 as components capable of contacting human skin have good biocompatibility and stable structural strength.

[0163] In some embodiments, the locking protrusion 187 can also protrude from the peripheral wall portion 711 or the end wall portion 712 and be arranged outside the battery compartment, and the locking slot 713 is arranged on the inner wall surface of the second housing 120. Details are not described herein.

[0164] In one embodiment, referring to FIG. 9, the peripheral wall portion 711 is provided with a third avoiding gap 714 extending from the peripheral wall portion 711 away from one end of the end wall portion 712 in the width direction of the battery window 100a to the end wall portion 712; it can also be understood that the third avoiding gap 714 is arranged through the peripheral wall portion 711 in the direction of the geometric center line of the battery compartment.

[0165] Correspondingly, the locking clamping groove 713 is arranged on the profile edge of the end wall portion 712 and communicates with the third avoiding gap 714; it can also be understood that the locking clamping groove 713 is arranged on the profile edge of the end wall portion 712 at a position corresponding to the third avoiding gap 714.

[0166] The third avoiding gap 714 can make the peripheral wall portion 711 or the battery support 710 have a condition of structural deformation, so as to facilitate the placement or removal of the battery 730 in or from the battery compartment; at the same time, it also provides structural support for the arrangement of the locking clamping groove 713.

[0167] In one embodiment, in the state that the battery support 710 (specifically, the peripheral wall portion 711) closes the battery window 120h, the third avoiding gap 714 is located in the accommodation cavity 100a; thus, it can avoid affecting the appearance structure of the device main body due to the exposure of the third avoiding gap 714 or the battery 730.

[0168] In one embodiment, referring to FIGS. 8 and 11, the battery support 710 further has a limiting portion 715 protruding from the outer wall surface of the peripheral wall portion 711, for example, protruding from the peripheral wall portion 711 at the third avoiding gap 714; for example, protruding from the peripheral wall portion 711 at a position close to the locking structure.

[0169] When the battery support 710 is rotated to a preset angle position in the accommodation cavity 100a through the battery window 120h, the limiting portion 715 can be used to abut against the inner wall surface (for example, the wall surface in the length direction of the battery window 120h) of the second housing 120 in the battery window 120h to limit the continuous rotation of the battery support 710, so that the locking clamping protrusion 187 can be clamped in the locking clamping groove 713; in this way, the limiting portion 715 can not only limit the rotation angle of the battery support 710, but also cooperate with the locking structure to stably lock the battery support 710 in the accommodation cavity 100a.

[0170] In one embodiment, referring to Figures 8 to 10 , the battery holder 710 further includes an operating portion 716 that protrudes from the outer circumference of the peripheral wall portion 711. When the battery holder 710 or the peripheral wall portion 711 is enclosing the battery window 120h, the operating portion 716 can protrude from the outer surface of the second housing 120. Regarding the specific location of the operating portion 716 on the peripheral wall portion 711, the operating portion 716 can be located near the locking structure or the stop portion 715.

[0171] The operating portion 716 can be used to apply a force to the battery holder 710 to cause it to rotate relative to the second housing 120 . For example, by toggling the operating portion 716 , the battery holder 710 can be rotated into and out of the accommodating cavity 100 a .

[0172] In one embodiment, referring to Figures 8 and 11, the battery holder 710 further has an anti-mistake portion 717, which is mainly used to identify the installation direction of the battery 730 to avoid the battery 730 being installed upside down; the anti-mistake portion 717 is arranged in the battery compartment and protrudes from the position where the peripheral wall portion 711 and the end wall portion 712 are connected; for example, the anti-mistake portion 717 can be a plurality of raised structures that are evenly and spaced apart around the geometric center line of the end wall portion 712 or the battery compartment.

[0173] Taking battery 730 as a button cell battery, for example, since the size or structural form of the positive terminal of a button cell battery is different from that of the negative terminal, when battery 730 is correctly placed in the battery compartment, the anti-mumble feature 717 can support the battery 730 from the negative terminal, and the positive terminal of the battery 730 can be kept roughly flush with the opening of the battery compartment. If the battery 730 is installed upside down, the anti-mumble feature 717 will cause the battery 730 to protrude from the opening of the battery compartment. Therefore, the anti-mumble feature 717 can help the user identify the installation direction of the battery 730.

[0174] In some embodiments, an anti-fool-proof mark may also be provided in the battery compartment. The anti-fool-proof mark may be a patch printed with patterns or texts, and fixed to the inner surface of the end wall portion 712 or the peripheral wall portion 711 by pasting; the anti-fool-proof mark may also be a pattern or text directly provided on the inner surface of the end wall portion 712 or the peripheral wall portion 711.

[0175] In one embodiment, referring to Figures 8, 11 and 12, the battery holder 710 further has an electrode window 718 provided through the end wall portion 712, and the electrode window 718 extends along the rotation trajectory of the battery holder 710 from the geometric center position of the end wall portion 712 to the position where the end wall portion 712 and the peripheral wall portion 711 are connected; it can also be understood that the electrode window 718 is an arc-shaped window structure arranged along the rotation trajectory of the battery holder 710.

[0176] The electrode window 718 is mainly used to provide structural support for the elastic contact connection between the electrode spring 720 and the battery 730; in particular, during the process of the battery holder 710 carrying the battery 730 to rotate into the accommodating cavity 100a through the battery window 120h, based on the existence of the electrode window 718, structural interference between the electrode spring 720 and the battery holder 710 can be avoided, so that the electrode spring 720 is always located within the contour range of the electrode window 718; when the battery holder 710 is rotated to the angle position where the locking structure is locked in the second shell 120, the electrode spring 720 can just contact (for example, elastically contact the negative terminal center of the button battery) the battery 730 at the geometric center of the end wall portion 712.

[0177] It can be understood that one end of the peripheral wall portion 711 in the direction of the rotation axis of the second rotation shaft structure (for example, the third direction) is connected to the end wall portion 712 and encloses the geometric center line of the end wall portion 712, so as to form an opening at the end of the peripheral wall portion 712 away from the end wall portion 712, which is the opening or opening end of the battery compartment; the electrode window 718 is opposite to the opening, and the electrode spring 720 can elastically abut on the battery 730 in the battery compartment through the electrode window 718 and the opening.

[0178] In one embodiment, referring to FIG. 12, the peripheral wall portion 711 is also provided with a fourth avoiding notch 719 which communicates with the electrode window 718; the fourth avoiding notch 719 can further eliminate the structural interference between the battery holder 710 and the electrode spring 720, and ensure that the battery holder 710 can normally and smoothly rotate relative to the second shell 120 without the interference of the electrode spring 720.

[0179] In one embodiment, referring to FIGS. 8 and 9 and FIGS. 11 and 12, the second rotation shaft structure includes a shaft sleeve portion 740 and a shaft rod portion 188; the shaft sleeve portion 740 is protruded from the outer surface of the peripheral wall portion 711; and the shaft rod portion 188 is arranged in the shaft sleeve portion 740 and the second shell 120 along the direction parallel to the geometric center line of the battery compartment or the width direction of the battery window 120h; for example, the shaft rod portion 188 is arranged in the form of penetrating the eighth shell wall 120c, the shaft sleeve portion 740 and the ninth shell wall 120d, to establish a rotating connection relationship between the second shell 120 and the battery holder 710.

[0180] In other embodiments, the shaft rod portion 188 can also be a protruding structure protruded from the two opposite inner wall surfaces of the second shell 120 in the width direction of the battery window 120h, which can be inserted into the shaft sleeve portion 740 to realize the rotating connection between the second shell 120 and the battery holder 710. All these will not be repeated here.

[0181] In one embodiment, referring to FIG. 13 and FIG. 14, the second housing 120 is provided with two electrode slots 189, which are located on opposite sides of the battery window 120h in the width direction of the battery window 120h (or the third direction of the housing assembly 100), and are used to accommodate and fix a corresponding electrode spring 720.

[0182] For the purpose of distinguishing and description, the two slot walls that are spaced apart from each other in the width direction of the battery window 120h are defined as a first slot side wall and a second slot side wall, and the slot wall that is connected between the first slot side wall and the second slot side wall is defined as a slot bottom wall; wherein, in the width direction of the battery window 120h, the first slot side wall is located away from the battery window 120h, and the second slot side wall is located close to the battery window 120h.

[0183] Exemplarily, taking the second housing 120 as the description reference, a protruding blocking wall can be arranged at the position where the tenth housing wall 120e is located on the contour edge of the battery window 120h, so as to form the second slot side wall; the first slot side wall can be a part of the eighth housing wall 120c and a part of the ninth housing wall 120d that face each other with respect to the corresponding second slot side wall; and the slot bottom wall can be a part of the tenth housing wall 120e.

[0184] As for the electrode spring 720, referring to FIG. 9, the electrode spring 720 includes a contact portion 721, a base portion 722, and a plurality of elastic portions 723; wherein, the base portion 722 is used to abut or abut against the second slot side wall in the electrode slot 189; the contact portion 721 is connected to the base portion 722 and extends out of the electrode slot 189, and is mainly used to elastically abut against the battery 730 arranged on the battery holder 710; and the plurality of elastic portions 723 are spaced apart from each other with respect to the base portion 722 in the width direction of the battery window 120h (or the third direction), and are mainly used to abut or abut against the first slot side wall in the electrode slot 189.

[0185] The fixed ends of the plurality of elastic portions 723 are respectively bent to connect with the base portion 722, and the bending directions of at least two of the plurality of elastic portions 723 with respect to the base portion 722 are different; for example, the fixed end of one elastic portion 723 is bent to connect with one end of the base portion 722 in a first direction, and the fixed end of another elastic portion 723 is bent to connect with one end of the base portion 722 in a second direction.

[0186] In one aspect, by virtue of the structure that the substrate portion 722 and the elastic portion 723 are bent to be in contact with each other and spaced apart from each other, the electrode spring 720 can be inserted and fixed in the electrode slot 189 stably, and the contact portion 721 can be kept in a position capable of elastically abutting against the battery 730, by virtue of the ability of the electrode spring 720 to elastically deform itself, so that the elastic portion 723 abuts against the first slot side wall and the substrate portion 722 abuts against the second slot side wall.

[0187] In another aspect, by virtue of the difference in the bending direction of the plurality of elastic portions 723 relative to the substrate portion 722, the electrode spring 720 can be limited and fixed in the electrode slot 189 from different directions, for example, the electrode spring 720 is limited to move in the electrode slot 189 in a plurality of directions such as the first direction, the second direction, and the third direction, so as to ensure the stability of the structure connection between the electrode spring 720 and the second housing 120.

[0188] In one embodiment, referring to FIG. 9, the plurality of elastic portions 723 includes a first elastic portion 723a, and the fixed end of the first elastic portion 723a is bent to be in contact with one end of the substrate portion 722 close to the slot bottom wall in the second direction. The gap between the first elastic portion 723a and the substrate portion 722 can be gradually increased from the fixed end of the first elastic portion 723a to the free end of the first elastic portion 723a, or it can be understood that the first elastic portion 723a is inclinedly bent relative to the substrate portion 722, and the first elastic portion 723a and the substrate portion 722 can jointly form a bent structure similar to a “V” shape.

[0189] When the second direction is from the slot opening end of the electrode slot 189 to the slot bottom wall side, and the electrode spring 720 is inserted into the electrode slot 189, the bent structure formed by the first elastic portion 723a and the substrate portion 722 can generate a reverse elastic pre-tightening force due to the abutting action of the first slot side wall and the second slot side wall, so that the first elastic portion 723a abuts against the first slot side wall and the substrate portion 722 abuts against the second slot side wall, thereby limiting the movement of the electrode spring 720 in the electrode slot 189 from the third direction and the second direction at the same time, and avoiding the electrode spring 720 from being accidentally pulled out of the electrode slot 189 due to the falling or collision of the device main body.

[0190] In one embodiment, referring to FIGS. 9, 13 and 14, the first slot side wall is provided with a second limiting protrusion 190 protruding therefrom, which can abut against the free end of the first elastic portion 723 from the second direction. As previously described, the cooperation between the first elastic portion 723a and the base portion 722 can limit the movement or shaking of the electrode tab 720 in the electrode slot 189 along the third direction; and the second limiting protrusion 190 can limit the movement or shaking of the electrode tab 720 in the electrode slot 189 along the second direction. It should be noted that in this embodiment, the first elastic portion 723a can be arranged parallel to the base portion 722, or the first elastic portion 723a can be arranged obliquely bent relative to the base portion 722.

[0191] In one embodiment, a sealant is arranged between the first elastic portion 723a and the first slot side wall, or between the first elastic portion 723a and the slot bottom wall, or between the first elastic portion 723a and both the first slot side wall and the slot bottom wall. The sealant can be used to firmly fix the first elastic portion 723a to the slot wall of the electrode slot 189, thereby further improving the stability and strength of the structural connection between the electrode tab 720 and the second housing 120.

[0192] In some embodiments, referring to FIG. 13, a second sealant groove 191 for accommodating the sealant can be arranged on the slot wall of the electrode slot 189 corresponding to the position of the first elastic portion 723 (e.g., the first slot side wall or the slot bottom wall), so as to increase the amount of sealant used and expand the contact area between the sealant and the first elastic portion 723 and the second housing 120 by means of the second sealant groove 191.

[0193] In one embodiment, referring to FIGS. 9, 13 and 14, the plurality of elastic portions 723 further includes a second elastic portion 723b and a third elastic portion 723c; wherein the fixed end of the second elastic portion 723b is bent to connect with one end of the base portion 722 in the first direction, and the fixed end of the third elastic portion 723c is bent to connect with one end of the base portion 722 in the second direction away from the slot bottom wall. Thus, the second elastic portion 723b and the third elastic portion 723c can be used to limit the movement or shaking of the electrode tab 720 in the electrode slot 189 from both the third direction and the first direction.

[0194] In one embodiment, referring to FIGS. 9, 13 and 14, a third limiting protrusion 192 and a fourth limiting protrusion 193 are arranged on the first slot side wall corresponding to the positions of the second elastic portion 723b and the third elastic portion 723c, respectively; wherein the third limiting protrusion 192 and the fourth limiting protrusion 193 can abut against the corresponding second elastic portion 723b and third elastic portion 723c from the third direction.

[0195] With the structure matching relationship between the second elastic part 723b and the third limiting protrusion 192 as an example, the third limiting protrusion 192 abutting against the second elastic part 723b can cause the second elastic part 723b to deform along the third direction towards the side of the substrate part 722, so that the second elastic part 723b generates an elastic pre-tightening force acting on the third limiting protrusion 192, thereby firmly abutting the second elastic part 723b against the first slot side wall, effectively improving the structural fixing effect of the electrode spring 720 and the second shell 120.

[0196] In some embodiments, according to the structural design requirements of the electrode slot 189 or the electrode spring 720, the number of the second elastic part 723b or the third elastic part 723c can be set to be multiple, and multiple second elastic parts 723b or multiple third elastic parts 723c are arranged at different positions of the substrate part 722; of course, the second elastic part 723b or the third elastic part 723c can also be omitted; all of these will not be repeated here.

[0197] In some embodiments, referring to FIG. 9, the first elastic part 723a is located between the second elastic part 723b and the third elastic part 723c in the first direction, which is conducive to stably fixing the electrode spring 720 in the electrode slot 189.

[0198] In one embodiment, referring to FIG. 9 and FIG. 14, the electrode spring 720 further includes a wiring part 724, which can be connected to one end of the substrate part 722 in the first direction (for example, the end away from the second side wall), and the wiring part 724 extends or protrudes out of the electrode slot 189.

[0199] The wiring part 724 can be used to weld and fix the wire assembly on the electrode spring 720, so that the battery assembly 700 establishes an electrical connection relationship with the control board assembly 200 through the wire assembly.

[0200] In one embodiment, referring to FIG. 9, the fixed end of the contact part 721 is bent to connect to the end of the substrate part 722 in the second direction away from the slot bottom wall, so that the contact part 721 can be inclined relative to the substrate part 722 towards the side of the second slot side wall away from the first slot side wall.

[0201] In other words, in the state that the battery holder 710 carrying the battery 730 is locked in the accommodating cavity 100a, the contact part 721 is inclined relative to the substrate part 722 towards the side of the battery holder 710 or the battery 730, so that the contact part 721 can effectively contact the battery 730.

[0202] In some embodiments, please refer to Figures 4, 9 and 14. For the convenience of distinction and description, one of the two electrode springs 720 is defined as a positive electrode spring 720a, and the other of the two electrode springs 720 is defined as a negative electrode spring 720b; for example, the one of the two electrode springs 720 that can elastically support the positive electrode of the battery 730 with the open end of the battery compartment is the positive electrode spring 720a, and the one of the two electrode springs 720 that can elastically support the negative electrode of the battery 730 in the electrode window 718 is the negative electrode spring 720b.

[0203] 4 , the inclination angle of the contact portion 721 of the positive electrode spring 720a relative to the base portion 722 of the positive electrode spring 720a is a first angle, and the inclination angle of the contact portion 721 of the negative electrode spring 720b relative to the base portion 722 of the negative electrode spring 720b is a second angle, and the first angle is set to be smaller than the second angle; illustratively, the first angle can be set to 3°-8°, and the second angle can be set to 15°-25°; for example, the first angle is 3° and the second angle is 25°.

[0204] Given that the positive and negative terminals of the battery 730 have different structural forms and sizes, in some embodiments where an anti-mute portion 717 is provided in the battery compartment, the depth to which the contact portion 721 of the negative electrode spring clip 720b needs to extend into the battery compartment is often greater than the depth to which the contact portion 721 of the positive electrode spring clip 720a needs to extend into the battery compartment.

[0205] Therefore, by differentially setting the inclination angles of the contact portions 721 of the positive spring sheet 720a and the negative spring sheet 720b, the positive and negative contact portions can adapt to the installation state of the battery 730 in the battery compartment, thereby effectively contacting the battery 730.

[0206] Taking into account many factors such as the overall size of the device body, the wall thickness of the battery holder 710 (such as the thickness of the end wall 712), the depth of the electrode spring 720 extending into the battery compartment, the degree of elastic deformation of the electrode spring 720, the pressure that the electrode spring 720 can provide to the battery 730, the degree of contact between the contact portion 721 and the battery 730, etc.; in one embodiment, the first angle is set to 5° and the second angle is set to 20°.

[0207] It should be noted that the two intersecting bold dotted lines in Figure 4 are only for showing the approximate angular relationship between the contact portion 721 of the positive spring piece 720a and the base portion 722, and the two intersecting bold solid lines in Figure 4 are only for showing the approximate angular relationship between the contact portion 721 of the negative spring piece 720b and the base portion 722.

[0208] The above describes the present application by using specific examples, 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, a person skilled in the art of the present application can make several simple deductions, deformations or substitutions.
