[0042] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements.

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.

[0043] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementation methods. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various orders in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and do not mean that they are necessary orders, unless otherwise specified that a certain order must be followed. The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "connection" mentioned in this application, unless otherwise specified, include direct and indirect connections (connections).

[0044] 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.

[0045] See also Figure 1 The wearable device includes a housing assembly 100, a movement assembly, a speaker device, and other functional components as needed.

[0046] 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.

[0047] The speaker device can be understood as a collection of related components that realize the function of playing sound signals of the wearable device. In some embodiments, the speaker device is connected to the device body, that is, the speaker device is connected and arranged outside the housing assembly 100.

[0048] For example, see Figure 1 The speaker device is an in-ear speaker, which includes a speaker component 810 and a wearing component 820; wherein the speaker component 810 is configured to be adaptably inserted into the user's ear canal, and mainly plays the role of playing sound signals to the user; the wearing component 820 is connected and arranged between the speaker component 810 and the shell component 100 in the form of electrically connecting the speaker component 810 and the core component, and is mainly used to establish a signal connection relationship between the core component and the speaker component 810.

[0049] The wearable component 820 can be a flexible cable with a signal transmission function, or other wires with both a signal transmission function and a shape memory function. One end of the wearable component 820 is fixed and electrically connected to the speaker component 810, and the other end of the wearable component 820 can be connected to the housing component 100 in a detachable or non-detachable manner and electrically connected to the movement component.

[0050] With the help of the wearing component 820, the device body can be stably worn on the user's ear, and the speaker component 810 can be inserted into the user's ear canal; the external sound signal can be collected through the device body (specifically, the movement component), and by converting the sound signal into an electrical signal and outputting it to the speaker component 810, the speaker component 810 can be used to play the corresponding sound signal to realize the hearing aid function of the wearable device.

[0051] In other embodiments, the speaker device can also be configured in other forms on the wearable device. For example, the reference movement component can be directly set inside or outside the shell component 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 between the two, hearing aids or other types of wearable devices such as headphones, glasses, etc. with other structural forms can also be constructed.

[0052] It is understood that when a wearable device is powered on, the cooperation between the core assembly and the speaker device can achieve the conversion between sound signals (such as mechanical vibration signals) and electrical signals, so that the user can hear the sound through the ears. Generally speaking, mechanical vibrations can act on the user's eardrum and auditory nerve based on the principle of air conduction, mainly through air as a medium. Mechanical vibrations can also act directly on the user's auditory nerve based on the principle of bone conduction, through the user's bones and tissue as a medium. With respect to the sound heard by the user, the former can be referred to as "air-conducted sound," and the latter can be simply referred to as "bone-conducted sound."

[0053] Based on this, by selecting and configuring the specific functional structures of the movement components and the speaker device, the wearable device can form both air-conducted sound and bone-conducted sound, and can also achieve air-conducted sound and bone-conducted sound at the same time.

[0054] In order to describe the structural construction of the device body more clearly and in detail, based on the outer contour of the device body, this article defines three directions that intersect or are perpendicular to each other, namely: a "first direction", a "second direction" and a "third direction".

[0055] For example, when the wearable device is in a certain natural placement state, the first direction may refer to the length direction of the entire device, the second direction may refer to the thickness direction of the entire device, and the third direction may refer to the width direction of the entire device.

[0056] For example, when the wearable device is normally worn between the back of the ear and the head, with the user as a reference, the first direction may refer to the up and down direction of the user, the second direction may refer to the front and back direction of the user, and the third direction may refer to the left and right direction of the user.

[0057] For one example, see Figures 1 to 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 opposite to each other and are matched and connected to form a accommodating cavity 100a inside the shell assembly 100 (or between the first shell 110 and the second shell 120); the movement assembly is arranged in the accommodating cavity 100a; wherein, at least a part of the movement assembly 100 is connected to the first shell 110, and at least another part of the movement assembly 100 is connected to the second shell 120.

[0058] For example, the core assembly includes a control panel 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 ease of distinction and description, the functional components of the core assembly connected to the first housing 110 are defined as first components, and the functional components of the core assembly connected to the second housing 120 are defined as second components. The first component may include the control panel assembly 200, the microphone assembly 300, and the key assembly 400; the second component may include the first interface assembly 500, the second interface assembly 600, and the battery assembly 700.

[0059] The microphone assembly 300 is electrically connected to the control board assembly 200 and is respectively fixed to the first shell 110; the microphone assembly 300 is mainly used to collect sound signals from the outside of the device (specifically, the outside of the shell assembly 100), for example, due to external environmental sounds, the relevant components of the microphone assembly 300 itself generate mechanical vibrations, thereby enabling the microphone assembly 300 to collect sound signals.

[0060] The control panel assembly 200 mainly plays a role in regulation and management in the wearable device. For example, the control panel assembly 200 can receive the sound signal collected by the microphone assembly 300, and then convert the sound signal into an electrical signal and output it to the speaker device (specifically, the speaker assembly 810), thereby playing the sound signal to the user with the help of the speaker device.

[0061] The button assembly 400 is movably connected to the first shell 110 and is arranged in coordination with the control panel assembly 200; through the coordination between the button assembly 400 and the control panel assembly 200, the input of preset instructions can be realized; for example, instructions for controlling the power on and off of the wearable device, instructions for volume adjustment or other instructions can be input to the control panel assembly 200 through the button assembly 400.

[0062] The first interface assembly 500, the second interface assembly 600, and the battery assembly 700 are connected to the second housing 120 and are electrically connected to the control board assembly 200; for example, an electrical signal connection is established with the control board assembly 200 via a wire assembly. The first interface assembly 500 primarily serves to connect the speaker device within the device body, for example, by being removably connected to the wearable assembly 820 in a pluggable manner, thereby establishing a signal connection between the speaker assembly 810 and the control board assembly 200, so that the speaker assembly 810 can generate or play sound signals in response to the electrical signals provided by the control board assembly 200.

[0063] The second interface assembly 500 is primarily used to connect to an external control device (such as a mobile phone or computer) to transmit data between the external control device and the wearable device. For example, the external control device can be used to adaptively adjust the wearable device's operating mode, operating parameters, volume, and other settings based on user needs. The battery assembly 700 is primarily used to power the electrical components of the wearable device, supporting its normal operation.

[0064] In some embodiments, other functional components may be added to the movement assembly or some functional components may be omitted. For example, the first interface assembly 500 may be omitted, and the speaker assembly 810 may be directly connected to the control board assembly 200 through the wearable assembly 820; for example, the second interface assembly 600 may be replaced with a wireless communication module, and data may be transmitted between the wearable device and the external control device with the help of the wireless communication module.

[0065] That is, the core assembly may include one or more of 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 .

[0066] In some embodiments, based on the internal structure of the shell assembly 100 , the functional components in the first assembly and the second assembly can also be interchanged with each other. For example, the first interface assembly 500 belongs to the first assembly and is connected to the first shell 110 .

[0067] That is to say, the control panel assembly 200, microphone assembly 300, button assembly 400, first interface assembly 500, second interface assembly 600 and 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.

[0068] It should be noted that the description of "wire assembly" is introduced in this article. The wire assembly can be a wire, a cable, a flexible printed circuit board (FPC), etc., to adapt to the internal structure of the shell assembly 100 and the spatial arrangement relationship between the relevant functional components, so as to flexibly establish an electrical connection relationship between the relevant functional components.

[0069] Based on this, with the first shell 110 and the second shell 120 as the installation carriers of multiple functional components inside the device, the core components can be dispersedly arranged in different parts of the shell assembly 100.

[0070] On the one hand, compared with the related art, in which an internal skeleton independent of the shell assembly 100 is used as the installation carrier of the movement assembly, the present application can fully utilize the shell structure and space, reduce the number of internal components of the device, and thus facilitate the miniaturization and lightweight design of the wearable device.

[0071] On the other hand, based on the structural form of the dispersed arrangement of the movement components, not only can the wearable device be quickly disassembled and assembled, but also by disassembling and assembling the first shell 110 and the second shell 120, the first component and the second component can be specifically disassembled, maintained, recycled and reused.

[0072] For one example, see Figures 4 to 7 The first shell 110 and the second shell 120 both adopt a shell structure with an opening. The first shell 110 and the second shell 120 are matched and connected in the second direction with the openings facing each other to enclose and form the accommodating cavity 100a.

[0073] As for the core components, the first component (such as the control panel component 200, the microphone component 300, the button component 400, etc.) is connected to the inner wall of the first shell 110, so that at least part of the first component is accommodated in the shell space of the first shell 110; the second component (such as the first interface component 500, the second interface component 600, the battery component 700, etc.) is connected to the inner wall of the second shell 120, so that at least part of the second component is accommodated in the shell space of the second shell 120.

[0074] First, by connecting the first component to the inner wall of the first shell 110 and the second component to the inner wall of the second shell 110, the connection structure between the movement component and the shell component 100 can be avoided from being exposed in the shell component 100 and affecting the appearance contour of the device body, thereby improving the appearance and wearability of the device body.

[0075] Secondly, using the shell space of the first shell 110 and the second shell 120 to accommodate the first component and the second component can play a certain protective role and prevent the first component or the second component from being damaged due to bumps before the shell component 100 is assembled.

[0076] Third, by setting the first shell 110 and the second shell 120 as a shell-type structure with a certain volume space inside and an opening, it is convenient to assemble the first shell 110 and the first component, and the second shell 120 and the second component respectively. After completing the wiring of the wire component, the assembly of the device body can be completed conveniently and quickly.

[0077] In some embodiments, the first housing 110 may be a housing-type structure with an opening, while the second housing 120 may be a cover-type structure. The second housing 120 is disposed on the first housing 110 to cover the opening of the first housing 110, thereby forming a housing cavity 100a with the first housing 110. Regarding the movement assembly, the first assembly is connected to the inner wall of the first housing 110 and accommodated within the housing space of the first housing 110. The second assembly is connected to a surface of the second housing 120 facing the first housing 110. After the first and second housings 110 are assembled, the second assembly is equivalently accommodated within the housing space of the first housing 110 (i.e., the housing cavity 100a). Of course, the first housing 110 may be a cover-type structure, while the second housing 120 may be a housing-type structure with an opening.

[0078] Therefore, the shell assembly 100 is formed by combining the shell structure with the cover structure, which is not only conducive to the rapid assembly of the device body, but also can form wearable devices with different structural forms or assembly methods, thereby meeting different application requirements.

[0079] For one example, see Figures 4 to 7 An assembly structure is provided between the first shell 110 and the second shell 120. The assembly structure is mainly used to assemble and fix the first shell 110 with the first component installed and the second shell 120 with the second component installed into one body, so as to roughly form a complete outer contour structure of the device body (i.e., the shell assembly 100), so that the wearable device or the device body can be moved, carried, worn, operated and used with the help of the shell assembly 100.

[0080] 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 a connection form such as gluing and welding between the first shell 110 and the second shell 120. For another example, the assembly structure can also be a related structure suitable for realizing a detachable connection form such as snapping and locking between the first shell 110 and the second shell 120.

[0081] For example, see Figures 4 to 7 The assembly structure includes a first fixing structure and a first positioning structure; wherein the first fixing structure is mainly used to firmly fix the first shell 110 and the second shell 120 into one; the first positioning structure is mainly used to locate the relative position between the first shell 110 and the second shell 120 to provide support for quick and accurate assembly of the first shell 110 and the second shell 120, and at the same time cooperate with the first fixing structure to enhance the structural combination strength of the first shell 110 and the second shell 120.

[0082] The first fixing structure includes a support arm 131 and a fixing pin 132 ; wherein the support arm 131 is protruding from the inner wall surface of the second shell 120 , for example, the support arm 131 and the second shell 120 are an integrated structure; the fixing pin 132 cooperates with the support arm 131 .

[0083] The first positioning structure includes a first positioning protrusion 141 and a first positioning slot 142; wherein, the first positioning protrusion 141 is protruding from the inner wall surface of the first shell 110, and the first positioning protrusion 141 and the first shell 110 are an integrated structure; the first positioning slot 142 is integrally formed in the position of the second shell 120 corresponding to the first positioning protrusion 141.

[0084] During 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 142 with the help of the alignment relationship between the first positioning protrusion 141 and the first positioning slot 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 are against each other, so that the first space and the second space are connected to form the accommodating cavity 100a (at this time, the support arm 131 is located in the accommodating cavity 100a).

[0085] Then, the fixing pin 132 is passed from the outside of the shell assembly 100 through the position of the first shell 110 corresponding to the support arm 131 (for example, a pin hole structure can be set at the position of the first shell 110 corresponding to the support arm 131) and into the interior of the shell assembly 100, so that the first shell 110 and the support arm 131 are penetrated and fixed as a whole, so as to finally realize the detachable assembly and fixation between the first shell 110 and the second shell 120.

[0086] In some embodiments, the support arm 131 and the fixing pin 132, the first positioning protrusion 141 and the first positioning slot 142 can also be swapped; for example, the support arm 131 is protruding from the inner wall of the first shell 110, and the first positioning protrusion 141 is protruding from the inner wall of the second shell 120.

[0087] With the help of the mutual cooperation between the first fixing structure and the first positioning structure, the assembly and fixation 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 device housing), and also provide structural support for the detachable assembly of the device body or the shell assembly 100.

[0088] For example, in the process of assembling the device 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 fixing pin 132 can be inserted by utilizing the matching relationship 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 guaranteed.

[0089] For example, when the device body needs to be disassembled for maintenance, the housing assembly 100 can be disassembled by simply pulling out the fixing pin 132 so as to inspect and maintain the internal structure and related components of the device body.

[0090] In some embodiments, the first fixing structure and the first positioning structure may also adopt other structural forms.

[0091] For example, a plurality of mutually cooperating snap structures are provided on the first shell 110 and the second shell 120 , and the snap structures are used to replace the first fixing structure and the first positioning structure to achieve assembly and fixation of the first shell 110 and the second shell 120 .

[0092] For another example, a convex shaft structure is set on the inner wall of the first shell 110 at a position corresponding to the support arm 131, and a pin hole structure for the convex shaft structure to be inserted is set on the support arm 131. The first fixing structure is formed by the cooperation of the convex shaft structure and the pin hole structure, so that with the cooperation of the first positioning structure, the first shell 110 and the second shell 120 can be positioned and fixed from different positions and different orientations.

[0093] In some embodiments, the first fixing structure may be omitted, and the first shell 110 and the second shell 120 may be pre-positioned by providing one or more first positioning structures, and then the first shell 110 and the second shell 120 may be finally fixed by gluing, welding, etc.

[0094] Of course, the first positioning structure can also be omitted, and multiple groups of support arms 131 and fixing pins 132 can be provided to fix the first housing 110 and the second housing 120 at multiple different positions.

[0095] For one example, see Figure 4 and Figure 5The first shell 110 and the second shell 120 are opposite to each other in the second direction and are matched to form a shell assembly 100, and the first fixing structure and the first positioning structure are arranged at the two opposite ends of the shell assembly 100 in the first direction; for the convenience 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; wherein, 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.

[0096] By placing the first fixing structure and the first positioning structure at opposite ends of the shell assembly 100, during the assembly process, the first shell 110 and the second shell 120 can be positioned and spliced in advance with the help of the first positioning structure, and then the first shell 110 and the second shell 120 can be fixed by utilizing the matching relationship between the fixing pin 132 and the support arm 131; this is conducive to the assembler 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 body; at the same time, it is also convenient to inspect and maintain its internal structure and related functional components by disassembling the shell assembly 100.

[0097] In some embodiments, the control panel 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-type structure; the support arm 131 is arranged roughly along the second direction toward the side where the first shell 110 is located, protruding from the inner wall of the second shell 120; the fixing pin 132 is arranged roughly along the third direction through the first shell 110 and the support arm 131; accordingly, the first positioning protrusion 141 is arranged roughly along the second direction toward the side where the second shell 120 is located, protruding from the inner wall or open end face of the second shell 120.

[0098] Therefore, based on the differentiated arrangement direction of the support arm 131 and the first positioning protrusion 141, the combination of the second shell 120 and the second component can be regarded as an installation body, guiding the assembler to quickly and accurately assemble the combined structure of the first shell 110 and the first component to the installation body.

[0099] For one example, see Figure 2 and Figure 3The first shell 110 and the second shell 120 both adopt a shell-type structure, and the core assembly includes a control panel 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.

[0100] For the convenience 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 connected between 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.

[0101] The two shell walls of the second shell 120 that are 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 that are 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 connected between 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.

[0102] The first shell wall 110a and the sixth shell wall 120a are combined to form the first side wall of the housing assembly 100, the second shell wall 110b and the seventh shell wall 120b are combined to form the second side wall of the housing assembly 100, the fifth shell wall 110e and the tenth shell wall 120e can be understood as the third and fourth side walls of the housing assembly 100 that are opposite to each other in the second direction, the third shell wall 110c and the eighth shell wall 120c are combined to form the fifth side wall of the housing assembly 100, and the fourth shell wall 110d and the ninth shell wall 120d are combined to form the sixth side wall of the housing assembly 100. It can be understood that the first, second, third, fourth, fifth, and sixth side walls of the housing assembly 100 are connected to form the accommodating cavity 100a.

[0103] See also Figure 2 The control panel 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 that can form "air-conducted sound", and the microphone assembly 300 is fixedly arranged on the third side wall and maintains air communication with the outside of the shell assembly 100 at the third side wall.

[0104] For example, 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 is arranged in communication with the microphone assembly 300, and the external sound signal is transmitted to the microphone assembly 300 using air as a medium, so as to enable the microphone assembly 300 to collect the sound signal by generating mechanical vibration.

[0105] For example, a sound-conducting pipe may be provided in the accommodating cavity 100 a , and the microphone assembly 300 is connected to the outside of the housing assembly 100 through the sound-conducting pipe, thereby collecting sound signals.

[0106] For some examples, see Figure 2 The number of microphone assemblies 300 is set to two, and the two microphone assemblies 300 are arranged on opposite sides of the control board assembly 200 in the first direction; as far as the device body is concerned, the two microphone assemblies 300 can collect sound signals from different directions.

[0107] See also Figure 2 and Figure 3 The button assembly 400 is arranged in the accommodating cavity 100a in the form of a movable connection (such as a rotating connection, a sliding connection, etc.) on the inner wall of the first shell 110, and the button assembly 400 is at least partially exposed on the third side wall.

[0108] For example, the button assembly 400 is arranged on one side of the control panel assembly 200 facing the third side wall in the second direction, and a button window 110g is set through the position of the third side wall corresponding to the button assembly 400. The button assembly 400 is exposed through the button window 110g and protrudes from the third side wall.

[0109] By applying a pressing force to the button assembly 400 toward one side of the control board assembly 200 , the button assembly 400 can be urged to press the button switch on the control board assembly 200 to implement input of a preset instruction.

[0110] In some embodiments, the button assembly 400 may also include a switch component capable of generating an electrical signal. The button assembly 400 is electrically connected to the control board assembly 200 , and command information is input to the control board assembly 200 by triggering the button assembly 400 .

[0111] See also Figure 2 and Figure 6The first interface component 500 is fixedly connected to the second shell 120 (for example, fixed to the fourth side wall) in a form that is at least partially exposed on the first side wall and arranged in the accommodating cavity 100a; illustratively, a first connection port 120f can be set through the first side wall, and the interface end of the first interface component 500 can be arranged to be opposite to and communicate with the first connection port 120f, and the interface end of the first interface component 500 can also extend into the first connection port 120f, and can also extend out of the shell component 100 from the first connection port 120f.

[0112] Correspondingly, an interface structure that can be pluggably connected to the first interface component 500 can be provided on the speaker device (specifically, the end of the wearable component 820 away from the speaker component 810). The interface structure and the first interface component 500 can be used to fix the speaker device to the device body, and realize the electrical connection between the speaker device and the core component (such as the control panel component 200).

[0113] See also Figure 2 and Figure 6 The second interface assembly 600 is fixedly connected to the second shell 120 (for example, fixed to the fourth side wall) in a manner that is at least partially exposed on the fifth side wall and arranged within the accommodating cavity 100a. For example, a second connection port 120g can be provided through the fifth side wall (for example, the eighth shell wall 120c). The interface end of the second interface assembly 600 can be arranged to be directly opposite and in communication with the second connection port 120g, and the interface end of the second interface assembly 600 can also extend into the second connection port 120g. During the application stage of the wearable device, the second interface assembly 600 can be used to connect to external control devices such as mobile phones and computers to adaptively adjust the operating mode and operating parameters of the wearable device according to the user's own needs.

[0114] See also Figures 2 to 4 and Figure 6 The battery assembly 700 can be fixedly connected to the second shell 120 or movably connected to the second shell 120; for example, a battery window 120h can be set in the area where the second side wall and the fourth side wall meet, and the battery assembly 700 is rotatably connected to the second shell 120, so that by rotating the battery assembly 700, the battery assembly 700 can enter and exit the accommodating cavity 100a through the battery window 120h to replace the battery.

[0115] Based on this, by distributing the various parts of the movement assembly in different positions or orientations of the shell assembly 100, not only can the structure and space of the shell assembly 100 be more reasonably utilized to ensure the performance of the device, but it also facilitates the operation of the wearable device.

[0116] For example, by arranging the first interface component 500 and the battery component 700 at opposite ends of the device body along the first direction, the button component 400 is arranged at a position between the first interface component 500 and the battery component 700 along the first direction; on the one hand, it is not only convenient to connect the speaker device (such as the wearable component 820) through the first interface component 500, but also convenient to replace the battery in the battery component 700; on the other hand, when the device is in the wearable state, the button component 400 can be roughly located in the middle of the rear side or the lower rear side of the device body, which not only makes it convenient to operate the button component 400, but also avoids the first interface component 500 and the battery component 700 from causing structural interference with the button component 400.

[0117] For another example, by arranging two microphone assemblies 300 on opposite sides of the button assembly 400 or the control panel assembly 200 in the first direction, the curved surface structure adopted by the third side wall can be utilized so that the sound pickup channels 110f corresponding to the two microphone assemblies 300 face different directions, thereby effectively preventing external sound signals from being blocked by parts of the user's body, thereby ensuring the effect of the microphone assembly 300 on sound signal collection.

[0118] In some embodiments, when the wearable device is in a normal wearing state, for example, the device body is hung on the back of the user's ear by the wearing component 820, and the speaker component 810 is inserted into the user's ear canal:

[0119] 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 area where the user's head and the back of the ear are connected in the second direction, the fourth side wall is the side wall facing or contacting the area where the user's head and the back of the ear are connected in the second direction, the fifth side wall is the side wall facing or contacting the back 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.

[0120] Among them, see Figures 1 to 3 and Figure 5 The dimensions of the housing assembly 100 in the first direction are configured to be larger than those in the second and third directions. The third and fourth sidewalls are configured to have curved surfaces that adapt to the physiological structure of the area where the back of the ear meets the head. The geometric centerline of the housing assembly 100 in the first direction is configured as an arc segment.

[0121] In this way, based on the size differences of the shell component 100 in different directions and the structural form of the side wall, the outer contour of the shell component 100 or the device body is constructed into a prosthetic structure, so that the shell component 100 or the device body can adapt to the physiological structure between the back of the ear and the head, so as to be worn on the ear in the form of being clamped or hung on the ear.

[0122] In embodiments where the housing assembly 100 employs a contoured structure, the dimensions of the housing assembly 100 in the third direction can be configured to gradually decrease from the second sidewall toward the first sidewall. That is, the dimensions of the first end of the housing assembly 100 in the third direction are smaller than those of the second end. This allows the width of the end of the device body in the first direction for connecting to the speaker (i.e., where the first interface assembly 500 is located) to be smaller than the width of the end where the battery assembly 500 is located, thus accommodating the spatial requirements of the housing assembly 100 as required by the battery assembly 500.

[0123] In some embodiments, the housing assembly 100 is made of polyimide (PI) material. For example, the first housing 110 and the second housing 120 are both made of an integrated structure of polyimide material, and the two are connected relative to each other to form the housing assembly 100 .

[0124] Compared with the related art, the body shell of the wearable device adopts materials such as polycarbonate (PC for short) material, ABS plastic (i.e., a terpolymer of three monomers: acrylonitrile (A), butadiene (B), and styrene (S)); in this embodiment, based on the good biocompatibility and high mechanical strength of the polyimide material, the structural form (including the appearance) of the shell assembly 100 can be made more stable, and the thickness of the shell is thinner, which is conducive to the miniaturization and lightweight of the wearable device and enhances the stability of the overall structure of the shell assembly 100.

[0125] As previously mentioned, the wearable device or device body may include a battery assembly 700, which is disposed within the accommodating cavity 100a in a manner directly connected to the housing assembly 100. The following description of the battery assembly 700 and its related structure primarily takes the example of the battery assembly 700 being connected to the second housing 120; however, it should be noted that the battery assembly 700 may also be connected to the first housing 110 or other suitable device housing structures.

[0126] For one example, see Figures 2 to 6 、 Figures 8 to 14The 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 connects the accommodating cavity 100a with the outside of the shell assembly 100; with respect to the shell assembly 100, the battery window 120h can be a strip 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.

[0127] The battery assembly 700 includes a battery holder 710 for accommodating a battery 730 and an electrode spring 720 for electrically connecting to the control board assembly 200. A second pivot structure and a locking structure are formed between the battery holder 710 and the second housing 120. The second pivot structure is used to establish a relatively rotatable structural connection between the battery holder 710 and the second housing 120, enabling the battery holder 710 to rotate relative to the second housing 120 about the second pivot structure (the direction of the rotation axis of the second pivot structure or the battery holder 710 is considered the third direction), thereby allowing the battery holder 710 to 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 housing 120 (for example, to maintain the battery holder 710 within the accommodating cavity 100a). Specifically, the locking structure can lock the battery holder 710 to the second housing 120 when the battery holder 710 closes the battery window 120h.

[0128] The electrode spring clip 720 is arranged in the accommodating cavity 100a and is fixedly connected to the second shell 120; for example, the number of the electrode spring clips 720 is set to two, and the two electrode spring clips 720 are arranged on the opposite 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 placed on the battery holder 710 is located in the accommodating cavity 100a, one end of the two electrode spring clips 720 can elastically support the positive and negative poles of the battery 730 respectively, and the other end of the two electrode spring clips 720 can be electrically connected to the control board assembly 200 through the wire assembly.

[0129] On the one hand, by using the second shell 120 as the installation carrier of the battery assembly 700 and distributing the components of the battery assembly 700 (i.e., the battery holder 710 and the electrode spring 720) in a dispersed manner on the second shell 120, the structural space of the second shell 120 or the shell assembly 100 can be fully utilized, which is conducive to achieving a lightweight and miniaturized design of the wearable device.

[0130] On the other hand, the battery holder 710 can be rotated out of the shell assembly 100 through the battery window 120h, which makes it easier to replace the battery 730. After the battery holder 710 is rotated into the accommodating cavity 100a, it can adapt to the structural form of the battery window 120h and achieve the closure of the battery window 120h, thereby maintaining the integrity of the outer contour structure of the device body.

[0131] It should be noted that the description of battery 730 in this embodiment is only for the purpose of understanding the structural structure and functional principle of battery holder 710, and does not necessarily mean that battery 730 is a component of battery assembly 700. In other words, in some embodiments, battery 730 can be a component of battery assembly 700; in other embodiments, battery 730 can also be a consumable component used with a wearable device.

[0132] For one example, see Figures 8 to 12 The battery holder 710 has a peripheral wall portion 711 and an end wall portion 712 that are connected to each other; wherein the peripheral wall portion 711 extends or is enclosed around the geometric center line of the end wall portion 712 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 outline of the battery holder 710 is roughly a cylindrical structure with a single end opening; for example, the battery compartment can accommodate a button battery, and the end wall portion 712 and the open end of the battery compartment are respectively opposite to the negative pole and the positive pole of the battery 730.

[0133] The second rotating shaft structure and the locking structure are disposed outside the battery compartment. The second rotating shaft structure may be formed between the second housing 120 and the peripheral wall portion 711. The axis of the second rotating shaft structure (or the rotation axis of the battery holder 710) is parallel to the geometric centerline of the battery compartment. The locking structure may be formed between the second housing 120 and the peripheral wall portion 711 or the end wall portion 712.

[0134] As for the relative position relationship between the second rotating shaft structure, the locking structure and the battery window 120h, the second rotating shaft structure and the locking structure are arranged on opposite sides of the battery window 120h in its length direction; from the perspective of the device body, the locking structure can be located at the bottom end of the device body or the shell assembly 100 in the up and down direction of the user.

[0135] Thus, the battery holder 710 can be unlocked and rotated quickly and conveniently at one end where the locking structure is located (for example, the bottom end of the device body), thereby improving the operating experience; at the same time, in some embodiments where the shell assembly 100 adopts a profiling structure, since the battery window 120h is equivalent to a strip window set through the second side wall and the fourth side wall of the shell assembly 100, the length trajectory of the battery window 120h is roughly an arc segment; therefore, with the help of the peripheral wall portion 711, the arc shape of the battery window 120h can be well adapted, and the battery window 120h can be closed by the peripheral wall portion 711, thereby ensuring the integrity of the outer contour structure of the device body.

[0136] In other embodiments, the battery holder 710 may also adopt other structural forms. For example, the battery holder 710 may be configured as a cover-type structure that is substantially the same as or matches the structure of the battery window 120h. The battery 730 is detachably mounted on the second housing 120 and located within the accommodating cavity 100a. The battery holder 710 can be used to open or close the battery window 120h. After the battery window 120h is opened, the battery 730 in the accommodating cavity 100a can be removed for replacement. Of course, the electrode spring 720 may also adopt other suitable structural components.

[0137] For one example, see Figure 8 and Figure 11 Combined with Figure 2 The locking structure includes a locking protrusion 187 and a locking slot 713; wherein the locking protrusion 187 protrudes from the inner wall surface of the second shell 120 (for example, the seventh shell wall 110b) and is arranged 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 is connected to the peripheral wall portion 712.

[0138] When the battery holder 710 is rotated toward the accommodating cavity 100a through the battery window 120h to a predetermined angle, the locking protrusion 187 is engaged with the locking groove 713, thereby restricting the battery holder 710 from further rotating and locking the battery holder 710 to the second housing 120.

[0139] In some embodiments, the battery holder 710 and the housing assembly 100 may be made of plastic material. For example, the battery holder 710 is an integral structure made of polyimide material, and the second housing 120 is an integral structure made of polyimide material.

[0140] On the one hand, the locking protrusion 187 formed on the second shell 120 can be inserted into the locking slot 713 in an interference fit manner, so as to stably lock the battery holder 710 on the second shell 120 by relying on the elastic deformation material property of the battery holder 710 or the second shell 120 itself; on the other hand, the battery holder 710 and the shell assembly 100, as components that can contact human skin, have good biocompatibility and stable structural strength.

[0141] In some embodiments, the locking protrusion 187 may also protrude from the peripheral wall portion 711 or the end wall portion 712 and be disposed outside the battery compartment, while the locking slot 713 is disposed on the inner wall surface of the second shell 120 ; details are not repeated here.

[0142] For one example, see Figure 9 The peripheral wall portion 711 is provided with a third avoidance gap 714, and the third avoidance gap 714 extends from the peripheral wall portion 711 from one end away from 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 avoidance gap 714 is arranged through the peripheral wall portion 711 in the direction of the geometric center line of the battery compartment.

[0143] Correspondingly, the locking slot 713 is arranged at the contour edge of the end wall portion 712 and is connected to the third avoidance gap 714; it can also be understood that the locking slot 713 is arranged at the contour edge of the end wall portion 712 corresponding to the position of the third avoidance gap 714.

[0144] The third avoidance gap 714 allows the peripheral wall portion 711 or the battery holder 710 to undergo structural deformation, making it easier to place the battery 730 in the battery compartment or remove the battery 730 from the battery compartment; at the same time, it also provides structural support for setting the locking slot 713.

[0145] In one embodiment, when the battery holder 710 (specifically, the peripheral wall portion 711 ) closes the battery window 120h , the third avoidance gap 714 is located within the accommodating cavity 100a ; thereby, the appearance structure of the device body is prevented from being affected by the exposure of the third avoidance gap 714 or the battery 730 .

[0146] For one example, see Figure 8 and Figure 11 The battery holder 710 further has a limiting portion 715, which is protruding from the outer wall surface of the peripheral wall portion 711, for example, protruding from the peripheral wall portion 711 at the third avoidance notch 714; for example, it is protruding from the peripheral wall portion 711 near the locking structure.

[0147] When the battery holder 710 rotates to a preset angle position through the battery window 120h toward the accommodating cavity 100a, the limiting portion 715 can be used to abut against the inner wall surface of the second shell 120 in the battery window 120h (for example, against the wall surface of the battery window 120h in the longitudinal direction) to limit the battery holder 710 from further rotation, so that the locking protrusion 187 can be just engaged in the locking groove 713; in this way, the limiting portion 715 can be used to limit the rotation angle of the battery holder 710 and cooperate with the locking structure to firmly lock the battery holder 710 in the accommodating cavity 100a.

[0148] For one example, see Figures 8 to 10 The battery holder 710 further includes an operating portion 716, which is disposed protruding from the outer circumference of the peripheral wall portion 711. When the battery holder 710 or the peripheral wall portion 711 closes the battery window 120h, the operating portion 716 may 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 may be disposed on the peripheral wall portion 711 near the locking structure or the limiting portion 715.

[0149] 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 .

[0150] For one example, see Figure 8 and Figure 11 The battery holder 710 also has an anti-mock 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-mock 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-mock portion 717 can be a plurality of raised structures that are evenly and spaced around the end wall portion 712 or the geometric center line of the battery compartment.

[0151] 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.

[0152] 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.

[0153] For one example, see Figure 8 、 Figure 11 and Figure 12 The battery holder 710 also has an electrode window 718 that passes through the end wall portion 712. The electrode window 718 extends from the geometric center position of the end wall portion 712 along the rotation trajectory of the battery holder 710 to the position where the end wall portion 712 and the peripheral wall portion 711 meet. 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.

[0154] 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; specifically, in the process of the battery holder 710 carrying the battery 730 rotating through the battery window 120h into the accommodating cavity 100a, 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 angular position locked by the locking structure in the second shell 120, the electrode spring 720 can just maintain contact with the battery 730 at the geometric center of the end wall portion 712 (for example, elastic contact at the center of the negative end of the button battery).

[0155] It can be understood that one end of the peripheral wall portion 711 in the direction of the rotation axis of the second rotating shaft structure (for example, in the third direction) is connected to the end wall portion 712 and is enclosed around the geometric center line of the end wall portion 712, so that an opening connected to the battery compartment can be formed at the end of the peripheral wall portion 712 away from the end wall portion 712, and the opening is the opening or the opening end of the battery compartment; and the electrode window 718 is opposite to the opening, and the electrode spring 720 can elastically support the battery 730 located in the battery compartment through the electrode window 718 and the opening.

[0156] For one example, see Figure 12 The peripheral wall portion 711 is further provided with a fourth avoidance notch 719, which is connected to the electrode window 718; the fourth avoidance notch 719 can further eliminate the structural interference between the battery holder 710 and the electrode spring 720, ensuring that the battery holder 710 can rotate normally and smoothly relative to the second shell 120 without interference from the electrode spring 720.

[0157] For one example, see Figure 8 and Figure 9 as well as Figure 11 and Figure 12 The second rotating shaft structure includes a sleeve portion 740 and a shaft portion 188; wherein the sleeve portion 740 is arranged to protrude from the outer surface of the peripheral wall portion 711; and the shaft portion 188 is arranged to pass through the sleeve portion 740 and the second shell 120 in a direction parallel to the geometric center line of the battery compartment or the width direction of the battery window 120h; for example, the shaft portion 188 establishes a rotational connection relationship between the second shell 120 and the battery holder 710 in the form of passing through the eighth shell wall 120c, the sleeve portion 740 and the ninth shell wall 120d.

[0158] In other embodiments, the shaft portion 188 may also be a protruding structure provided on two inner walls of the second housing 120 that are opposite in the width direction of the battery window 120h. The protruding structure can be inserted into the shaft sleeve portion 740 to achieve a rotational connection between the second housing 120 and the battery holder 710. These details are not further described here.

[0159] For one example, see Figure 13 and Figure 14 The second shell 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 shell assembly 100), and the electrode slots 189 are used to accommodate and fix a corresponding electrode spring 720.

[0160] For the convenience of distinction and description, the two groove walls of the electrode slot 189 that are spaced opposite to each other in the width direction of the battery window 120h are defined as the first groove side wall and the second groove side wall, and the groove wall connected between the first groove side wall and the second groove side wall is defined as the groove bottom wall; wherein, in the width direction of the battery window 120h, the first groove side wall is located on the side away from the battery window 120h, and the second groove side wall is located on the side close to the battery window 120h.

[0161] Exemplarily, with the second shell body 120 as a description reference, a raised retaining wall can be provided at the position of the tenth shell wall 120e at the edge of the contour of the battery window 120h to form a second groove side wall; the first groove side wall can be a part of the eighth shell wall 120c and a part of the ninth shell wall 120d facing each other with the corresponding second groove side wall; the groove bottom wall can be a part of the tenth shell wall 120e.

[0162] For the electrode spring 720, please refer to Figure 9The 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 side wall of the second slot in the electrode slot 189; the contact portion 721 is connected to the base portion 722 and extends from the electrode slot 189, and is mainly used to elastically abut against the battery 730 placed on the battery holder 710; the elastic portion 723 and the base portion 721 are spaced apart and opposite to each other in the width direction (or the third direction) of the battery window 120h, and are mainly used to abut or abut against the side wall of the first slot in the electrode slot 189.

[0163] The fixed ends of the multiple elastic parts 723 are each bent and connected to the base part 722, and at least two of the multiple elastic parts 723 have different bending directions relative to the base part 722; for example, the fixed end of one elastic part 723 is bent and connected to one end of the base part 722 in the first direction, and the fixed end of the other elastic part 723 is bent and connected to one end of the base part 722 in the second direction.

[0164] On the one hand, by virtue of the structural characteristics that the base portion 722 and the elastic portion 723 are bent and connected and spaced relative to each other, the electrode spring 720 itself can rely on its ability to produce elastic deformation, so that the elastic portion 723 abuts against the side wall of the first groove and the base portion 722 abuts against the side wall of the second groove, so that the electrode spring 720 is firmly inserted and fixed in the electrode slot 189, and the contact portion 721 can be maintained in a position where it can elastically abut against the battery 730.

[0165] On the other hand, by utilizing the different bending directions of multiple elastic parts 723 relative to the base part 722, the electrode spring 720 can be restricted and fixed in the electrode slot 189 from different directions, for example, the electrode spring 720 can be restricted to move in the electrode slot 189 along multiple directions such as the first direction, the second direction and the third direction, thereby ensuring the stability of the structural connection between the electrode spring 720 and the second shell 120.

[0166] For one example, see Figure 9 The plurality of elastic portions 723 include a first elastic portion 723a, the fixed end of the first elastic portion 723a being bent and connected to an end of the base portion 722 in the second direction, which is close to the bottom wall of the groove. The gap between the first elastic portion 723a and the base portion 722 can be configured to gradually increase from the fixed end of the first elastic portion 723a toward the free end of the first elastic portion 723a. Alternatively, the first elastic portion 723a can be bent obliquely relative to the base portion 722, and the first elastic portion 723a and the base portion 722 can together form a bend structure that is approximately "V"-shaped.

[0167] When the electrode spring 720 is inserted into the electrode slot 189 in the second direction from the slot end of the electrode slot 189 toward the side of the slot bottom wall, the bending structure formed by the first elastic part 723a and the base part 722 will generate a reverse elastic pre-tightening force due to the pressure of the first slot side wall and the second slot side wall, so that the first elastic part 723a is pressed against the first slot side wall and the base part 722 is pressed 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 preventing the electrode spring 720 from accidentally falling out of the electrode slot 189 due to the falling or collision of the equipment body.

[0168] For one example, see Figure 9 、 Figure 13 and Figure 14 A second limiting protrusion 190 is protruding from the side wall of the first groove. The second limiting protrusion 190 can abut the free end of the first elastic portion 723 from the second direction. As previously described, the first elastic portion 723a cooperates with the base portion 722 to limit the movement or shaking of the electrode spring 720 in the electrode slot 189 along the third direction; and the second limiting protrusion 190 can limit the electrode spring 720 from the second direction, preventing the electrode spring 720 from moving or shaking 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 at an angle relative to the base portion 722.

[0169] In one embodiment, a sealant is provided between the first elastic portion 723a and the side wall of the first groove, or a sealant is provided between the first elastic portion 723a and the bottom wall of the groove, or a sealant is provided between the first elastic portion 723a and the side wall and bottom wall of the first groove; with the help of the sealant, the first elastic portion 723a can be firmly fixed on the groove wall of the electrode slot 189, further improving the stability and connection strength of the structural connection between the electrode spring clip 720 and the second shell 120.

[0170] For some examples, see Figure 13 A second glue containing groove 191 for accommodating sealant can be provided on the groove wall of the electrode slot 189 at a position corresponding to the first elastic part 723 (for example, the side wall or bottom wall of the first groove), so as to increase the amount of sealant used and expand the contact area between the sealant and the first elastic part 723 and the second shell 120 with the help of the second glue containing groove 191.

[0171] For one example, see Figure 9 、 Figure 13 and Figure 14The multiple elastic portions 723 further include a second elastic portion 723b and a third elastic portion 723c. The second elastic portion 723b has a fixed end that is bent and connected to one end of the base portion 722 in the first direction, while the third elastic portion 723c has a fixed end that is bent and connected to one end of the base portion 722 in the second direction that is away from the bottom wall of the slot. Thus, the second elastic portion 723b and the third elastic portion 723c can simultaneously restrict movement or shaking of the electrode spring 720 within the electrode slot 189 in both the third and first directions.

[0172] For one example, see Figure 9 、 Figure 13 and Figure 14 A third limiting protrusion 192 and a fourth limiting protrusion 193 are respectively provided on the side wall of the first groove corresponding to the second elastic part 723b and the third elastic part 723c; wherein, the third limiting protrusion 192 and the fourth limiting protrusion 193 can be used to support the corresponding second elastic part 723b and the third elastic part 723c from the third direction.

[0173] Taking the structural cooperation relationship between the second elastic part 723b and the third limiting protrusion 192 as an example, using the third limiting protrusion 192 to support the second elastic part 723b can cause the second elastic part 723b to deform along the third direction toward the side of the base part 722, so that the second elastic part 723b can generate an elastic pre-tightening force that reacts to the third limiting protrusion 192, thereby firmly supporting the second elastic part 723b against the side wall of the first groove, effectively improving the structural fixing effect of the electrode spring piece 720 and the second shell 120.

[0174] 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 portion 723b or the third elastic portion 723c can be set to multiple, and multiple second elastic portions 723b or multiple third elastic portions 723c are arranged at different positions of the base portion 722 at intervals; of course, the second elastic portion 723b or the third elastic portion 723c can also be omitted; all these will not be elaborated here.

[0175] For some examples, see Figure 9 The first elastic portion 723a is located between the second elastic portion 723b and the third elastic portion 723c in the first direction, which is conducive to stably fixing the electrode spring 720 in the electrode slot 189.

[0176] For one example, see Figure 9 and Figure 14The electrode spring 720 also includes a wiring portion 724, which can be connected to one end of the base portion 722 in the first direction (for example, the end away from the second side wall), and the wiring portion 724 extends from or protrudes from the electrode slot 189.

[0177] The wire assembly can be welded and fixed to the electrode spring 720 by means of the wiring portion 724 , so that the battery assembly 700 can establish an electrical connection with the control board assembly 200 through the wire assembly.

[0178] For one example, see Figure 9 The fixed end of the contact portion 721 is bent and connected to one end of the base portion 722 away from the bottom wall of the groove in the second direction, so that the contact portion 721 can be tilted relative to the base portion 722 toward the side of the second groove sidewall facing away from the first groove sidewall.

[0179] In other words, when the battery holder 710 carrying the battery 730 is locked in the accommodating cavity 100a, the contact portion 721 is tilted relative to the base portion 722 toward the side where the battery holder 710 or the battery 730 is located, so that the contact portion 721 can effectively contact the battery 730.

[0180] In some embodiments, please combine Figure 4 、 Figure 9 and Figure 14 For the convenience of distinction and description, one of the two electrode springs 720 is defined as the positive electrode spring 720a, and the other of the two electrode springs 720 is defined as the 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.

[0181] Among them, see Figure 4 The inclination angle of the contact portion 721 of the positive electrode spring piece 720a relative to the base portion 722 of the positive electrode spring piece 720a is a first angle, and the inclination angle of the contact portion 721 of the negative electrode spring piece 720b relative to the base portion 722 of the negative electrode spring piece 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°.

[0182] 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.

[0183] 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.

[0184] 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°.

[0185] It should be noted that Figure 4 The two intersecting bold dashed lines in FIG. 7 are only for illustrating the approximate angular relationship between the contact portion 721 of the positive spring 720 a and the base portion 722 . Figure 4 The two intersecting bold solid lines in FIG. 7 are only for illustrating the approximate angular relationship between the contact portion 721 of the negative electrode spring 720 b and the base portion 722 .

[0186] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
