[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on March 8, 2024, with application number 202410268620.7 and application name “Functional module, shell manufacturing method and wearable device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electronic equipment, and in particular to a functional module, a shell manufacturing method and a wearable device. Background Art

[0003] In recent years, wearable electronic devices (hereinafter referred to as wearable devices), such as smart watches and smart bracelets, have gradually emerged. They can be worn on the body and provide various functions and services. By connecting to devices such as smartphones, they can monitor health indicators, record exercise data, provide navigation information, etc. In the fields of health and fitness, they can help monitor health conditions, manage exercise, provide notifications and navigation functions in work and life, and improve efficiency and convenience. They have become a part of people's daily lives and provide users with personalized services and experiences. Wearable devices have some built-in functional devices, such as microphones and barometers. These devices require through holes to be opened on the outer shell of the wearable device to facilitate communication with the outside world. When the through holes are opened on the middle frame of the outer shell, they are easily observed by users. When the number of through holes increases, the risk of moisture entering the inner shell increases, affecting the waterproof performance of the watch, and also increases the risk of dust and dirt accumulating inside the outer shell. Summary of the Invention

[0004] The present application provides a functional module, a shell manufacturing method and a wearable device to solve the problem that when multiple functional devices are set, the increase in the number of through holes will increase the risk of moisture entering the interior of the shell, and will also increase the risk of dust and dirt accumulating inside the shell.

[0005] The technical solution is as follows:

[0006] A first aspect of the present application provides a functional module, applied to a wearable device, comprising: a housing and a device module;

[0007] The housing has a first side surface and a second side surface, the first side surface is provided with a first mounting groove and a second mounting groove, and the housing is provided with a first through hole; the first mounting groove is connected to the first through hole, and the second mounting groove is connected to the first through hole; an opening of the first through hole is located on the second side surface;

[0008] The device module includes a first sub-device and a second sub-device. The first sub-device is installed in the first installation groove, and the second sub-device is installed in the second installation groove.

[0009] By adopting the above solution, the present application directly opens the first mounting groove and the second mounting groove for mounting the first sub-component and the second sub-component on the housing. On the one hand, this can simplify the number of parts of the functional module, optimize the functional module, reduce complexity, and reduce the difficulty of assembly. On the other hand, it is conducive to making the overall size of the functional module smaller and saving space. On the third hand, it is conducive to improving the stability and reliability of the functional module and better controlling the sealing performance. After the first mounting groove and the second mounting groove are opened on the housing, they are combined with the first through hole on the housing so that different sub-components in the functional module can share the first through hole on the housing, thereby reducing the number of holes observed from the outside of the housing, thereby reducing the risk of water ingress and reducing the risk of dust and dirt entering the housing and accumulating.

[0010] In some implementations, the first side surface and the second side surface are disposed opposite each other, the first side surface is located on an inner side of the housing, and the second side surface is located on an outer side of the housing;

[0011] The shell also has a first channel, and the first installation groove and the first through hole are communicated through the first channel.

[0012] By adopting the above solution, the first channel connected to the first mounting groove is also provided on the shell, which is conducive to reducing the complexity of the functional module; the device module is installed on the inner side of the shell, and an orifice of the first through hole is located on the outer side of the shell opposite to the inner side, which is conducive to reducing the communication path between the first mounting groove and the second mounting groove and the first through hole respectively, which is conducive to reducing the number of holes observed from the outside of the shell while ensuring the stability of the functions of each sub-component of the device module.

[0013] In some implementations, the second mounting slot is in direct communication with the first through hole;

[0014] The first channel is a groove structure, the groove structure is located at the bottom of the first installation groove, and a portion of the groove wall of the groove structure is flush with a portion of the groove wall of the first installation groove.

[0015] By adopting the above solution, the second mounting groove is directly connected to the first through hole, so as to shorten the distance between the second sub-component installed in the second mounting groove and the outside world, thereby ensuring the stability of the performance of the sub-component in the device module; and part of the groove wall of the groove structure is flush with part of the groove wall of the first mounting groove, so that the diameter of the hole on the second side of the first through hole can be as small as possible, and the distance between the first sub-component installed in the first mounting groove and the outside world is shortened, thereby ensuring the stability of the performance of the sub-component in the device module.

[0016] In some implementations, the functional module further includes a first bracket and a first sealing ring, the first sub-component is installed in the first mounting groove through the first bracket, and the first sealing ring is installed between the first bracket and the first mounting groove by interference fit.

[0017] By adopting the above solution, the first bracket can support the installation of the sub-component of the device module, and cooperate with the first sealing ring to ensure the sealing performance of the first sub-component after being installed in the first installation groove.

[0018] In some implementations, the first bracket includes a bottom plate portion and a blocking portion connected to the bottom plate portion, wherein the blocking portion is disposed around a circumference of the bottom plate portion;

[0019] The bottom plate portion is provided with a communicating hole which is communicated with the first channel.

[0020] By adopting the above solution, a mounting cavity can be formed by utilizing the enclosure portion and the bottom plate portion, so as to facilitate the mounting of the first sub-component.

[0021] In some implementations, the housing further has a second channel, and the second mounting groove is connected to the first through hole through the second channel.

[0022] By adopting the above solution, the second channel communicating with the second mounting groove is also provided on the housing, which helps to reduce the complexity of the functional module.

[0023] In some implementations, the first side further defines a third mounting groove connected to the first through hole, and the third mounting groove is located between the first mounting groove and the second mounting groove; the device module further includes a third sub-device; and the third sub-device is installed in the third mounting groove.

[0024] By adopting the above solution, more sub-components can be mounted on the housing, so that more sub-components share the first through hole, thereby reducing the number of holes observed from the outside of the housing.

[0025] In some implementations, the first through hole, the first channel, and the second channel are integrally formed.

[0026] By adopting the above-mentioned solution, the first through hole, the first channel and the second channel are integrally formed to form a fluid channel, rather than being formed by assembling and piecing together functional modules. This one-piece design helps to ensure the stability and sealing of the fluid channel, while also improving the overall performance and reliability of the functional module, and is conducive to simplifying the manufacturing and assembly process.

[0027] In some implementations, one of the first sub-component and the second sub-component is a microphone, and the other is a barometer.

[0028] By adopting the above solution, sharing the same first through hole for the microphone and the barometer can improve the aesthetics of the wearable device and increase space utilization, thereby achieving a simple and compact design, and helping to improve the dust and water resistance of the wearable device.

[0029] In some implementations, the opening of the first through hole located on the second side is circular;

[0030] Alternatively, the opening of the first through hole located on the second side surface is in a strip shape.

[0031] By adopting the above solution, when machining the first channel and the first through-hole from the second side surface of the housing, the opening of the first through-hole on the second side surface is elongated due to the machining process, which facilitates machining of the first channel and the first through-hole. Furthermore, when machining the first channel, the second channel, and the first through-hole from the first and second side surfaces of the housing, the opening of the first through-hole on the second side surface can be circular, which reduces the aperture diameter and facilitates dust and water resistance.

[0032] In some implementations, the functional module further includes a pressing plate, which is detachably fixedly connected to the first side surface of the housing;

[0033] The device module is located between the first side surface and the pressing plate.

[0034] By adopting the above solution, the stability of the device module installation can be achieved by using the pressure plate.

[0035] In some implementations, the shell is a middle frame or a bottom shell; wherein the material of the middle frame is metal, or the material of the middle frame is plastic, or the material of the middle frame includes metal and plastic.

[0036] By adopting the above solution, regardless of whether the housing is a middle frame or a bottom shell, the number of middle frames can be reduced by having multiple sub-components share one first through hole; and the material of the middle frame can be set as needed.

[0037] A second aspect of the present application provides a shell manufacturing method for manufacturing the shell in any of the above-mentioned functional modules;

[0038] The shell manufacturing method includes:

[0039] Processing the first side surface of the semi-finished product to form a first mounting groove and a second mounting groove;

[0040] A first through hole is opened on the semi-finished product to form a shell of the semi-finished product, wherein the first through hole is connected to the first mounting groove, and the first through hole is also connected to the second mounting groove, and an opening of the first through hole is located on the second side of the semi-finished product.

[0041] By adopting the above solution, the present application directly opens the first mounting groove and the second mounting groove for mounting the first sub-component and the second sub-component on the housing. On the one hand, this can simplify the number of parts of the functional module, optimize the functional module, reduce complexity, and reduce the difficulty of assembly. On the other hand, it is conducive to making the overall size of the functional module smaller and saving space. On the third hand, it is conducive to improving the stability and reliability of the functional module and better controlling the sealing performance. After the first mounting groove and the second mounting groove are opened on the housing, they are combined with the first through hole on the housing so that different sub-components in the functional module can share the first through hole on the housing, thereby reducing the number of holes observed from the outside of the housing, thereby reducing the risk of water ingress and reducing the risk of dust and dirt entering the housing and accumulating.

[0042] In some implementations, opening a first through hole in a semi-finished product includes:

[0043] Processing from the second side surface of the semi-finished product, processing a first through hole on the second side surface, so that the first through hole is directly connected to the second mounting groove;

[0044] The shell manufacturing method further includes: opening a first channel on the bottom of the first through hole so that the first channel is connected to the first installation groove;

[0045] When the first channel is processed, the opening of the first through hole on the second side surface is in a strip shape.

[0046] By adopting the above solution, when the first channel and the first through hole are processed from the second side of the shell, due to the processing technology, the opening of the first through hole located on the second side is long and strip-shaped, so that the first channel and the first through hole can be processed more conveniently.

[0047] In some implementations, the housing manufacturing method further includes:

[0048] Processing from a first side surface of the semi-finished product, a first channel is machined in the first mounting groove, and a second channel is machined in the second mounting groove;

[0049] The first through hole is formed in the semi-finished product, comprising:

[0050] Processing from the second side surface of the semi-finished product, processing a first through hole on the second side surface, so that the first through hole is connected to the first channel and the second channel respectively;

[0051] When the first through hole is processed, the opening of the first through hole on the second side surface is circular.

[0052] By adopting the above scheme, the first side and the second side of the shell are processed to form the first channel, the second channel and the first through hole, so that the opening of the first through hole located on the second side can be made circular, which can reduce the aperture and is beneficial to dust and water prevention.

[0053] In some implementations, the housing manufacturing method further includes:

[0054] Processing from a first side surface of the semi-finished product to form a first channel in the first mounting groove;

[0055] The first through hole is formed in the semi-finished product, comprising:

[0056] Processing from the second side surface of the semi-finished product, processing a first through hole on the second side surface, connecting the first through hole with the first channel, and directly connecting the first through hole with the second mounting groove;

[0057] When the first through hole is processed, the opening of the first through hole on the second side surface is circular.

[0058] By adopting the above solution, the first channel and the first through hole are processed from the first side and the second side of the shell, so that the opening of the first through hole located on the second side can be made circular, which can reduce the aperture and is beneficial to dust and water prevention.

[0059] In some implementations, the housing manufacturing method further includes:

[0060] Processing the first side surface of the semi-finished product to form a third mounting groove;

[0061] Before opening the first through hole on the semi-finished product, the shell manufacturing method also includes: processing the second side of the semi-finished product to form a first channel, a second channel and a third channel, so that the first channel, the second channel and the third channel are respectively connected to the first installation groove, the second installation groove and the third installation groove in a one-to-one correspondence.

[0062] By adopting the above solution, more sub-components can be mounted on the housing, so that more sub-components share the first through hole, thereby reducing the number of holes observed from the outside of the housing.

[0063] A third aspect of the present application provides a wearable device, which includes a housing, a speaker, and any functional module provided in the above implementation method, wherein the speaker and the device module are respectively located on opposite sides of the housing.

[0064] By adopting the above solution, after the functional module is applied to the wearable device, the first and second mounting grooves for mounting the first and second sub-components are directly opened on the shell. On the one hand, this can simplify the number of parts of the functional module, optimize the functional module, reduce complexity, and reduce the difficulty of assembly. On the other hand, it is conducive to making the overall size of the functional module smaller and saving space. On the third hand, it is conducive to improving the stability and reliability of the functional module and better controlling the sealing performance. After the first and second mounting grooves are opened on the shell, they are combined with the first through hole on the shell. In this way, different sub-components in the functional module can share the first through hole on the shell, thereby reducing the number of holes observed from the outside of the shell, thereby reducing the risk of water ingress and reducing the risk of dust and dirt entering the shell and accumulating.

[0086] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0087] It should be understood that the “multiple” mentioned in this application refers to two or more. In the description of this application, unless otherwise specified, “ / ” means or, for example, A / B can mean A or B; “and / or” in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solution of this application, words such as “first” and “second” are used to distinguish between identical or similar items with basically the same functions and effects. Those skilled in the art can understand that words such as “first” and “second” do not limit the quantity and execution order, and words such as “first” and “second” do not necessarily limit them to be different.

[0088] In the related art, wearable electronic devices (hereinafter referred to as wearable devices), such as smart watches, smart bracelets, etc., can be worn on the body to provide various functions and services, and because they have strong decorative properties, creating a better product appearance and enhancing aesthetics are important factors in improving product competitiveness. For wearable devices, some functional devices are built in, such as microphones, barometers, etc. These devices need to have through holes on the outer shell of the wearable device to facilitate communication with the outside world. When the through holes are opened on the middle frame of the outer shell, they are easily observed by users. When the number of through holes increases, the risk of moisture entering the inside of the outer shell increases, affecting the waterproof performance of the watch, and also increasing the risk of dust and dirt accumulating inside the outer shell. To this end, the embodiments of the present application provide a functional module, a shell manufacturing method and a wearable device to solve the problems in the related art.

[0089] The functional module, shell manufacturing method and wearable device provided in the embodiments of the present application are explained in detail below.

[0090] FIG1 is a schematic diagram of the structure of a wearable device provided in an embodiment of the present application. Referring to FIG1 , in one or more embodiments, the wearable device provided in the present application can be worn on a user's body, such as on an arm, wrist, neck, finger, or head. The wearable device includes a housing 101, a strap 102, and a display screen 103. The strap 102 is connected to the housing 101 to secure the wearable device to the user. The strap 102 and the housing 101 can be connected in a detachable manner. The display screen 103 is mounted on the housing 101. The housing 101 may also be mounted with essential components of the wearable device, such as a motherboard (not shown). The motherboard may include a controller to control the display screen 103. The embodiments of the present application do not impose any specific restrictions on the specific type of wearable device. For example, the wearable device may be an armband, a smartwatch, a finger ring, a collar, a sports bracelet, a sports watch, a health tracker, etc. For example, the embodiments of the present application use a watch as an example for the wearable device.

[0091] 1 , in some embodiments, the housing 101 may be rectangular. In this case, the watch 100 may be called a square watch. In other cases, the housing 101 may be of other shapes, such as circular. The fixing band 102 102 may be a watch strap.

[0092] For ease of description, as shown in Figure 1, the length direction of a wearable device can be defined as AA, the width direction can be defined as BB, and the thickness direction can be defined as CC. The AA, BB, and CC directions are perpendicular to each other and form a rectangular coordinate system.

[0093] FIG2 is a schematic diagram of the structure of the wearable device provided in an embodiment of the present application when the fixing strap 102 is not installed; as shown in FIG2 , in some embodiments, the housing 101 includes a middle frame 104 and a bottom shell 105; the bottom shell 105 and the display screen 103 are respectively installed on both sides of the thickness direction of the middle frame 104. The thickness direction of the middle frame 104 is parallel to the CC direction. For example, as shown in FIG2 , the middle frame 104 has a first through hole 106. When viewed from the outside of the wearable device, the opening of the first through hole 106 is in the shape of an elongated strip, for example, the opening is in the shape of a waist circle, and the waist circle is mainly composed of two straight lines and two arcs; the two straight lines are parallel and of equal length, and the two ends of the arc are respectively connected to the ends of the two straight lines; of course, the opening of the first through hole 106 can also be in other shapes, such as a rectangle or an ellipse.

[0094] Figure 3 is a cross-sectional view along line DD in Figure 2. As shown in Figure 3, in some embodiments, the wearable device includes a speaker 107, which is installed on one side in the width direction of the wearable device. Sound can be played through the speaker 107; and the speaker 107 is electrically connected to the motherboard.

[0095] In some embodiments, the wearable device further includes a functional module 108, which includes a housing and a device module 109. The device module 109 is mounted on the housing; the housing can be the middle frame 104 or the bottom housing 105; and the device module 109 is electrically connected to the mainboard. For example, referring to FIG3 , this application uses the housing as the middle frame 104 as an example for specific description. In FIG3 , the device module 109 is located on the other side of the wearable device in the width direction, so that the function of the device module 109 is not easily affected by the speaker 107. It should be noted that in some other possible embodiments, the housing can also be the bottom housing 105.

[0096] Figure 4 is a partial enlarged schematic diagram of point E in Figure 3; in combination with Figures 3 and 4, in some embodiments, the shell has a first side surface 110 and a second side surface 111, the first side surface 110 is provided with a first mounting groove 112 and a second mounting groove 113, and the shell is provided with a first through hole 106, that is, the middle frame 104 has a first side surface 110 and a second side surface 111, and the middle frame 104 is provided with a first mounting groove 112, a second mounting groove 113 and a first through hole 106; the first mounting groove 112 is connected to the first through hole 106, and the second mounting groove 113 is connected to the first through hole 106; an orifice of the first through hole 106 is located on the second side surface 111; the device module 109 includes a first sub-component 114 and a second sub-component 115, the first sub-component 114 is installed in the first mounting groove 112, and the second sub-component 115 is installed in the second mounting groove 113. In at least one embodiment, the present application directly opens multiple mounting slots on the housing for mounting multiple sub-components, that is, directly opens a first mounting slot 112 and a second mounting slot 113 on the housing for mounting a first sub-component 114 and a second sub-component 115. On the one hand, this can simplify the number of parts of the functional module 108, optimize the functional module 108, reduce complexity, and reduce the difficulty of assembly. On the other hand, it is conducive to making the overall size of the functional module 108 smaller and saving space. On the third hand, it is conducive to improving the stability and reliability of the functional module 108 and better controlling the sealing performance. In addition, after the first mounting slot 112 and the second mounting slot 113 are opened on the housing, they are combined with the first through hole 106 on the housing so that different sub-components in the functional module 108 can share the first through hole 106 on the housing, thereby reducing the number of holes observed from the outside of the housing, thereby reducing the risk of water ingress and reducing the risk of dust and dirt entering the housing and accumulating.

[0097] As shown in Figures 3 and 4, in some embodiments, the other opening of the first through hole 106 is respectively connected to the first mounting groove 112 and the second mounting groove 113; the first sub-component 114 and the second sub-component 115 are arranged side by side along the length direction of the wearable device, and there are no screws 119 or other fasteners between the first sub-component 114 and the second sub-component 115, so that the distance between the first sub-component 114 and the second sub-component 115 can be as small as possible, which is conducive to reducing the area of ​​the opening of the first through hole 106 observed from the outside of the wearable device, thereby reducing the risk of water ingress and reducing the risk of dust and dirt entering the shell and accumulating. For example, as shown in Figures 3 and 4 , the first sub-component 114 is a microphone, and the second sub-component 115 is a barometer. A sealing assembly 116 is also installed in the first mounting groove 112. The first sub-component 114 is mounted in the first mounting groove 112 via the sealing assembly 116. The sealing assembly 116 may include a stacked foam layer and a waterproof, sound-permeable membrane. The sealing assembly 116 prevents water from entering the microphone through the microphone's sound pickup hole. A second sealing ring 117 is sleeved over the barometer. The second sealing ring 117 forms an interference fit between the barometer and the wall of the second mounting groove 113, thereby preventing water or dust from entering the wearable device. It should be noted that in some other embodiments, when the second mounting groove 113 is used to mount the barometer, the wall of the second mounting groove 113 may include an annular boss. This boss serves to position the second sealing ring 117, ensuring that it does not shift within the second mounting groove 113 and improving sealing performance.

[0098] 3 and 4 , in some embodiments, the functional module 108 further includes a pressure plate 118, which is fixedly connected to the housing via screws 119, that is, the pressure plate 118 is fixedly connected to the middle frame 104; the screws 119 are located at both ends of the pressure plate 118 in the length direction, and the first sub-component 114 and the second sub-component 115 are located between the two ends of the pressure plate 118 in the length direction, and the first sub-component 114 and the second sub-component 115 are pressed and mounted on the housing via the pressure plate 118. It should be noted that the pressure plate 118 is not limited to being fixedly connected to the housing via screws 119, and other methods can also be used to achieve a fixed connection between the pressure plate 118 and the housing, for example, by engaging the pressure plate 118 to achieve a fixed connection between the pressure plate 118 and the housing.

[0099] As shown in Figure 4, in some embodiments, the first side 110 and the second side 111 are arranged opposite to each other, the first side 110 is located on the inner side of the shell, and the second side 111 is located on the outer side of the shell; the shell also has a first channel 120, and the first mounting groove 112 is connected to the first through hole 106 through the first channel 120, so that the first channel 120 connected to the first mounting groove 112 is also arranged on the shell, which is conducive to reducing the complexity of the functional module 108; the device module 109 is installed on the inner side of the shell, and an orifice of the first through hole 106 is located on the outer side of the shell opposite to the inner side, which is conducive to reducing the communication path between the first mounting groove 112 and the second mounting groove 113 and the first through hole 106 respectively, and while reducing the number of holes observed from the outside of the shell, it can also ensure the stability of the functions of each sub-component of the device module 109. For example, as shown in FIG4 , the first side 110 is the inner side of the middle frame 104, while the second side 111 is the outer side of the middle frame 104. Since the housing can be the middle frame 104, the first channel 120 is located on the middle frame 104. In the length direction of the wearable device, i.e., the AA direction, the first mounting slot 112 and the second mounting slot 113 are offset from the first channel 120. This prevents damage to the sub-device when a user inserts a rod-shaped object, such as a needle, through the first through-hole 106. Furthermore, the axial direction of the first channel 120 is at an angle to the axial direction of the first through-hole 106, i.e., they are non-parallel, which further prevents poking and protects against water and dust. The axial direction of the first through-hole 106 is parallel to the BB direction.

[0100] In some embodiments, as shown in FIG4 , the opening of the first through hole 106 located on the second side surface 111 is in the shape of an elongated strip. The first channel 120 and the first through hole 106 in FIG4 are primarily formed by machining from the second side surface 111 of the housing. Due to the machining process, the opening of the first through hole 106 located on the second side surface 111 in FIG4 is in the shape of an elongated strip, which facilitates machining of the first channel 120 and the first through hole 106. Furthermore, either a tapered shank drill or a straight shank drill can be used to machine the first channel 120 and the first through hole 106, the specific drill being determined based on actual needs.

[0101] FIG5 is a schematic diagram of the structure of the middle frame 104 of the wearable device provided by the embodiment of the present application, and FIG6 is a partially enlarged schematic diagram of point F in FIG5 . As shown in FIG5 and FIG6 , in some embodiments, the second mounting groove 113 is directly connected to the first through hole 106, and the groove wall of the second mounting groove 113 has an opening 123, so that it is directly connected to the first through hole 106 through the opening 123. This facilitates the processing of the first through hole 106 and reduces the area of ​​the opening of the first through hole 106. Exemplarily, the second mounting groove 113 and the first mounting groove 112 in FIG5 and FIG6 are suitable for installing the first sub-component 114 and the second sub-component 115 in FIG3 and FIG4.

[0102] FIG7 is another structural schematic diagram of the wearable device provided in an embodiment of the present application when the fixing strap 102 is not installed; as shown in FIG7 , when viewed from the outside of the wearable device, the opening of the first through hole 106 on the middle frame 104 is in a waist-shaped shape.

[0103] Figure 8 is a cross-sectional view taken along line GG in Figure 7, and Figure 9 is a partially enlarged schematic diagram of point H in Figure 8. As shown in Figures 8 and 9, the first sub-component 114 is a barometer, and the second sub-component 115 is a microphone. The barometer is sealed with the first mounting groove 112 by a second sealing ring 117, and the microphone is mounted in the second mounting groove 113 by a sealing assembly 116. The barometer and microphone are fixed to the middle frame 104 via a pressure plate 118. The first mounting groove 112 is indirectly connected to the first through-hole 106 via a first channel 120, while the second mounting groove 113 is directly connected to the first through-hole 106. The axial direction of the first channel 120 is at an angle to the axial direction of the first through-hole 106, i.e., they are non-parallel. This provides enhanced protection against punctures and provides water and dust resistance. The axial direction of the first through-hole 106 is parallel to the BB direction. The second mounting groove 113 may be stepped, that is, the second mounting groove 113 includes a first sub-groove portion 121 and a second sub-groove portion 122 . The second sub-groove portion 122 is located at the bottom of the first sub-groove portion 121 and communicates with the first through hole 106 .

[0104] It should be noted that in some other embodiments, when the first mounting groove 112 is used to mount a barometer, an annular boss may be provided on the groove wall of the first mounting groove 112. This boss can limit the position of the second sealing ring 117 and ensure that the second sealing ring 117 does not shift within the second mounting groove 113, thereby improving sealing performance. Furthermore, the difference between FIG. 8 and FIG. 3 primarily lies in the different installation positions of the microphone and the barometer. In FIG. 3 , the microphone is mounted in the first mounting groove 112, and the barometer is mounted in the second mounting groove 113; in FIG. 8 , the microphone is mounted in the second mounting groove 113, and the barometer is mounted in the first mounting groove 112.

[0105] In some embodiments, as shown in FIG9 , the opening of the first through hole 106 located on the second side surface 111 is in the shape of an elongated strip. The first channel 120 and the first through hole 106 in FIG9 are primarily formed by machining from the second side surface 111 of the housing. Due to the machining process, the opening of the first through hole 106 located on the second side surface 111 in FIG9 is in the shape of an elongated strip, which facilitates machining of the first channel 120 and the first through hole 106.

[0106] FIG10 is a schematic diagram of the structure of the middle frame 104 of the wearable device provided by the present application; FIG11 is a partially enlarged schematic diagram of point J in FIG10; As shown in FIG10 and FIG11, in some embodiments, the bottom and wall of the second mounting groove 113 have an opening 123, that is, the opening 123 is formed on the bottom and wall of the groove, so that it is directly connected to the first through hole 106 through the opening 123, which facilitates the processing of the first through hole 106 and reduces the area of ​​the opening of the first through hole 106. Exemplarily, the second mounting groove 113 and the first mounting groove 112 in FIG10 and FIG11 are suitable for installing the first sub-component 114 and the second sub-component 115 in FIG8 and FIG9.

[0107] FIG12 is a partial structural diagram of the functional module 108 provided in an embodiment of the present application; FIG12 shows only a partial structure of the shell; FIG13 is a sectional view along the KK line in FIG12, and FIG14 is a partial structural diagram of the shell provided in an embodiment of the present application; the shell shown in FIG14 is the shell of the functional module 108 in FIG12; in combination with FIG12 and FIG13, in some embodiments, the second mounting groove 113 is directly connected to the first through hole 106; the first channel 120 is a groove structure, the groove structure is located at the bottom of the first mounting groove 112, and part of the groove wall of the groove structure is connected to the first mounting groove 112. Part of the groove walls are flush with each other, so that the second mounting groove 113 is directly connected to the first through hole 106, so as to shorten the distance between the second sub-component 115 installed in the second mounting groove 113 and the outside world, thereby ensuring the stability of the performance of the sub-component in the device module 109; and part of the groove wall of the groove structure is flush with part of the groove wall of the first mounting groove 112, so that the diameter of the hole of the first through hole 106 on the second side 111 can be as small as possible, and shorten the distance between the first sub-component 114 installed in the first mounting groove 112 and the outside world, thereby ensuring the stability of the performance of the sub-component in the device module 109. For example, as shown in FIG13 and FIG14, the first sub-component 114 is a microphone, the second sub-component 115 is a barometer, the barometer is interference-fitted with the second mounting groove 113 through a second sealing ring 117, and the microphone is installed in the first mounting groove 112 through a sealing component 116; the bottom and the wall of the second mounting groove 113 have an opening 123, that is, the opening 123 is formed on the bottom and the wall of the groove, so that it is directly connected to the first through hole 106 through the opening 123, which makes it easy for the first through hole to be installed. 106 is processed to reduce the area of ​​the opening of the first through hole 106; the first channel 120 is in the shape of a long strip, one end of the first channel 120 is roughly located at the center of the bottom of the first mounting groove 112, and the other end of the first channel 120 is located at the groove wall of the first mounting groove 112. The first channel 120 is connected with the first through hole 106, so that the first mounting groove 112 is connected to the first through hole 106 through the first channel 120, realizing indirect connection between the first mounting groove 112 and the first through hole 106.

[0108] It should be noted that part of the groove wall of the groove structure is flush with part of the groove wall of the first mounting groove 112, and can be completely flush or approximately flush. In addition, in some other possible embodiments, the first through hole 106 can also be directly connected to the first mounting groove 112 and the second mounting groove 113 respectively.

[0109] As shown in Figures 13 and 14, in some embodiments, the functional module 108 also includes a first bracket 124 and a first sealing ring 125. The first sub-component 114 is installed in the first mounting groove 112 through the first bracket 124. The first sealing ring 125 is installed between the first bracket 124 and the first mounting groove 112 by interference fit. Since the other end of the first channel 120 is located at the groove wall of the first mounting groove 112, the first channel 120 is located at the groove bottom of the first mounting groove 112. In this way, the first channel 120 causes a concave notch to appear at the groove bottom of the first mounting groove 112. The first bracket 124 can be used to support the edge of the bottom of the sealing assembly 116 to ensure the performance of the sealing assembly 116, and then cooperate with the first sealing ring 125 to ensure the sealing performance of the first sub-component 114 after being installed in the first mounting groove 112.

[0110] As shown in Figures 13 and 14, in some embodiments, the first bracket 124 includes a bottom plate portion 126 and a blocking portion 127 connected to the bottom plate portion 126, and the blocking portion 127 is arranged around the circumference of the bottom plate portion 126; the bottom plate portion 126 has a connecting hole 128, and the connecting hole 128 is connected to the first channel 120, so that an installation cavity can be formed by using the blocking portion 127 and the bottom plate portion 126 to facilitate the installation of the first sub-component 114. Exemplarily, the bottom plate portion 126 is circular, and the connecting hole 128 is located at the center of the bottom plate portion 126. The bottom plate portion 126 can support the periphery of the bottom of the sealing assembly 116; the enclosure portion 127 is barrel-shaped, and the bottom plate portion 126 and the enclosure portion 127 are arranged perpendicularly to each other; the first bracket 124 also includes a side dam portion 129, which is connected to the enclosure portion 127. The bottom plate portion 126 and the side dam portion 129 are respectively located at the two ends of the height direction of the barrel-shaped enclosure portion 127, and the height direction of the enclosure portion 127 is parallel to the BB direction. The side dam portion 129 extends toward the groove wall of the first mounting groove 112; in the case of interference fit, the first sealing ring 125 will be deformed, and the side dam portion 129 can further ensure the waterproof and dustproof effects.

[0111] As shown in Figures 13 and 14 , in some embodiments, the opening of the first through hole 106 located on the second side 111 is circular. The first channel 120 and the first through hole 106 in Figures 13 and 14 are primarily formed by machining from the first side 110 and the second side 111 of the housing. This allows the opening of the first through hole 106 located on the second side 111 to be circular, thereby reducing the aperture and facilitating dust and water resistance. Furthermore, either a tapered shank drill or a straight shank drill can be used to machine the first channel 120 and the first through hole 106, with the specific drill being determined based on actual needs.

[0112] FIG15 is a partial structural diagram of another functional module 108 provided in an embodiment of the present application; FIG16 is a partial structural diagram of another functional module 108 provided in an embodiment of the present application; Referring to FIG15 and FIG16 , the housing further comprises a second channel 130, and the second mounting slot 113 is connected to the first through hole 106 via the second channel 130. Thus, the second channel 130 connected to the second mounting slot 113 is also provided on the housing, which helps to reduce the complexity of the functional module 108. For example, in FIG15 and FIG16 , the first mounting slot 112 is indirectly connected to the first through hole 106 via the first channel 120, the second mounting slot 113 is indirectly connected to the first through hole 106 via the second channel 130, the first sub-component 114 is a microphone, and the second sub-component 115 is a barometer. It should be noted that the main difference between Figure 15 and Figure 16 is that in Figure 15, the first channel 120, the second channel 130, and the first through hole 106 are mainly processed and formed by a straight shank drill bit, while in Figure 16, the first channel 120, the second channel 130, and the first through hole 106 are mainly processed and formed by a tapered shank drill bit; compared with the use of a straight shank drill bit, the use of a tapered shank drill bit is conducive to obtaining a larger first channel 120 and second channel 130, thereby improving permeability.

[0113] As shown in Figures 15 and 16 , in some embodiments, the axial direction of the first channel 120 is angled relative to the axial direction of the first through-hole 106, and the axial direction of the second channel 130 is angled relative to the axial direction of the first through-hole 106, i.e., they are arranged non-parallel. This further enhances puncture resistance and provides water and dust resistance. In the BB direction, the distance between the barometer and the opening of the first through-hole 106 on the second side 111 is smaller than the distance between the microphone and the opening of the first through-hole 106 on the second side 111. This improves the sensitivity of the barometer and ensures its performance.

[0114] As shown in Figures 15 and 16, the opening of the first through hole 106 located on the second side 111 is circular. The first channel 120, the second channel 130 and the first through hole 106 in Figures 15 and 16 are mainly formed by processing from the first side 110 and the second side 111 of the shell; this processing method can make the opening of the first through hole 106 located on the second side 111 circular, which can reduce the aperture, thereby facilitating dust and water prevention.

[0115] In some embodiments, the first through hole 106, the first channel 120, and the second channel 130 are integrally formed. In this way, the first through hole 106, the first channel 120, and the second channel 130 are integrally formed to form a fluid channel, rather than being formed by assembling the functional module 108. This integrally formed design helps ensure the stability and sealing of the fluid channel, while also improving the overall performance and reliability of the functional module 108, and is conducive to simplifying the manufacturing and assembly process. For example, in Figures 15 and 16, the first through hole 106, the first channel 120, and the second channel 130 are integrally formed.

[0116] Figure 17 is a partial structural diagram of another functional module 108 provided in an embodiment of the present application; as shown in Figure 17, the first side surface 110 is further provided with a third mounting groove 131 connected to the first through hole 106, and in the length direction of the wearable device, the third mounting groove 131 is located between the first mounting groove 112 and the second mounting groove 113; the device module also includes a third sub-device 132; the third sub-device 132 is installed on the third mounting, so that more sub-devices can be installed on the shell, that is, more sub-devices can be installed on the middle frame, so that more sub-devices share the first through hole 106 to reduce the number of holes observed from the outside of the shell. Exemplarily, the first mounting groove 112 is indirectly connected to the first through hole 106 through the first channel 120, the second mounting groove 113 is indirectly connected to the first through hole 106 through the second channel 130, the first sub-component 114 is a microphone, the second sub-component 115 is a barometer, and the third sub-component 132 can be a balancing valve (also known as a waterproof breathable membrane assembly); the shell also has a third channel 133, and the third mounting groove 131 is connected to the first through hole through the third channel 133.

[0117] It should be noted that the number of mounting slots on the first side 110 and the number of sub-components in the device module 109 can be arranged in a one-to-one correspondence, that is, one sub-component is installed in each mounting slot. Of course, in some other cases, the correspondence may not be one-to-one. For example, multiple sub-components, such as two or three, may be installed in one mounting slot. Furthermore, the number of mounting slots on the first side 110 can be more than two, and the first side 110 can also include a fourth mounting slot. The number of sub-components in the device module 109 can be more than two or three, and the device module 109 can also include a fourth sub-component, with the fourth sub-component installed in the fourth mounting slot.

[0118] As shown in FIG17 , in some embodiments, the axial direction of the first channel 120 is angled with the axial direction of the first through hole 106 , the axial direction of the second channel 130 is angled with the axial direction of the first through hole 106 , and the axial direction of the third channel 133 is angled with the axial direction of the first through hole 106 , i.e., they are arranged non-parallel. This further prevents puncture and provides water and dust resistance. The first through hole 106 , the first channel 120 , the second channel 130 , and the third channel 133 are integrally formed. Thus, the first through hole 106 , the first channel 120 , the second channel 130 , and the third channel 133 are integrally formed to form a fluid channel, rather than being formed by assembling the functional module 108 . This integrally formed design helps ensure the stability and sealing of the fluid channel, while also improving the overall performance and reliability of the functional module 108 and simplifying the manufacturing and assembly process.

[0119] In some embodiments, the length of the first through hole 106 in the length direction of the wearable device ranges from 0.6 mm to 1.3 mm, for example, 0.6 mm, 0.7 mm, 0.8 mm, 1.0 mm, 1.2 mm, or 1.3 mm. The width of the first through hole 106 in the thickness direction of the wearable device ranges from 0.6 mm to 5.0 mm, for example, 0.6 mm, 0.7 mm, 0.8 mm, 1.0 mm, 1.1 mm, 2.0 mm, 2.5 mm, 3.0 mm, 4.0 mm, or 5.0 mm.

[0120] In some embodiments, the housing is a middle frame 104 or a bottom housing 105; wherein the middle frame 104 is made of metal, or plastic, or a combination of metal and plastic. Regardless of whether the housing is the middle frame 104 or the bottom housing 105, multiple sub-components can share a single first through-hole 106, thereby reducing the number of middle frames 104; and the material of the middle frame 104 can be set as needed. It should be noted that when the middle frame 104 is made of metal and plastic, the middle frame 104 can be formed as an integrated structure using an insert injection molding process of metal and plastic.

[0121] It should be noted that in some other possible embodiments, a hydrophobic coating may be provided on the inner wall of the first channel 120; a hydrophobic coating may be provided on the inner wall of the second channel 130; and a hydrophobic coating may be provided on the inner wall of the first through hole 106. The hydrophobic coating may be a fluorocarbon coating or a silicone hydrophobic coating, which facilitates achieving a waterproof function.

[0122] In one or more embodiments, the present application further provides a housing manufacturing method, which is used to manufacture the housing in the functional module 108 in any embodiment of the present application;

[0123] The shell manufacturing method includes: machining a first side surface 110 of a semi-finished product to form a first mounting groove 112 and a second mounting groove 113; and forming a first through hole 106 in the semi-finished product to form a shell. The first through hole 106 is connected to the first mounting groove 112, and the first through hole 106 is also connected to the second mounting groove 113. An opening of the first through hole 106 is located on the second side surface 111 of the semi-finished product. The shell manufacturing method in the embodiment of the present application directly forms the first mounting groove 112 and the second mounting groove 113 in the shell for mounting the first sub-component 114 and the second sub-component 115. Firstly, this simplifies the number of parts of the functional module 108, optimizes the functional module 108, reduces complexity, and reduces assembly difficulty. Secondly, it helps to reduce the overall size of the functional module 108, saving space. Thirdly, it helps to improve the stability and reliability of the functional module 108 and better control the sealing performance. After the first mounting groove 112 and the second mounting groove 113 are opened on the shell, the first through hole 106 on the shell is matched so that different sub-components in the functional module 108 can share the first through hole 106 on the shell, thereby reducing the number of holes observed from the outside of the shell, thereby reducing the risk of water ingress and reducing the risk of dust and dirt entering the shell and accumulating.

[0124] In some embodiments, a method for forming a first through hole 106 in a semi-finished product includes: machining the first through hole 106 on the second side 111 of the semi-finished product, so that the first through hole 106 is directly connected to the second mounting groove 113. The housing manufacturing method further includes: forming a first channel 120 at the bottom of the first through hole 106, so that the first channel 120 is connected to the first mounting groove 112. After the first channel 120 is machined, the opening of the first through hole 106 on the second side 111 is strip-shaped. Thus, when machining the first channel 120 and the first through hole 106 from the second side 111 of the housing, the opening of the first through hole 106 on the second side 111 is elongated due to the machining process, making it easier to machine the first channel 120 and the first through hole 106. For example, this method can be used to achieve the first through hole 106 and the first channel 120 of the housing of the functional module 108 shown in Figures 4 and 9.

[0125] In other embodiments, the shell manufacturing method further includes: processing from the first side 110 of the semi-finished product to form a first channel 120 in the first mounting groove 112. The method of opening the first through hole 106 in the semi-finished product includes: processing from the second side 111 of the semi-finished product to form the first through hole 106 on the second side 111, so that the first through hole 106 is connected to the first channel 120, and the first through hole 106 is directly connected to the second mounting groove 113; wherein, after the first through hole 106 is processed, the opening of the first through hole 106 on the second side 111 is circular; in this way, by processing from the first side 110 and the second side 111 of the shell to form the first channel 120 and the first through hole 106, the opening of the first through hole 106 located on the second side 111 can be circular, which can reduce the aperture, thereby facilitating dust and water resistance. For example, the first through hole 106 of the shell of the functional module 108 in Figure 14 can be implemented using this method.

[0126] In some other embodiments, the housing manufacturing method further includes: machining from the first side 110 of the semi-finished product to form a first channel 120 in the first mounting groove 112, and machining a second channel 130 in the second mounting groove 113. A method for forming the first through hole 106 in the semi-finished product includes: machining from the second side 111 of the semi-finished product to form the first through hole 106 on the second side 111, so that the first through hole 106 is connected to the first channel 120 and the second channel 130, respectively; wherein, after the machining of the first through hole 106 is completed, the opening of the first through hole 106 on the second side 111 is circular. By machining from the first side 110 and the second side 111 of the housing to form the first channel 120, the second channel 130, and the first through hole 106, the opening of the first through hole 106 on the second side 111 can be circular, thereby reducing the aperture and facilitating dust and water resistance. For example, the first through hole 106 , the first channel 120 , and the second channel 130 of the functional module 108 in FIG. 15 and FIG. 16 may be implemented using this method.

[0136] FIG20 is a flow chart of another housing manufacturing method provided in an embodiment of the present application. Referring to FIG20 , in yet another embodiment, the housing manufacturing method of the embodiment of the present application can be used to manufacture the housing of the functional module 108 in FIG17 . The housing manufacturing method includes:

[0137] Step S301: Processing a first mounting groove 112, a second mounting groove 113, and a third mounting groove 131 on the first side surface 110 of the semi-finished product.

[0139] Step S303: Processing from the second side surface 111 of the semi-finished product, use a straight shank drill bit 201 to process the first through hole 106 on the second side surface 111, so that the first channel 120, the second channel 130 and the third channel 133 share the first through hole 106, and form a shell with the semi-finished product, which can be the middle frame 104. Figure (d) in Figure 20 shows that the first through hole 106 is formed after the processing is completed.

[0140] To sum up, the functional module 108, the shell manufacturing method and the wearable device provided in the embodiment of the present application directly open multiple installation slots such as the first installation slot 112, the second installation slot 113, and the third installation slot 131 on the shell, and also open a first through hole 106 on the shell, and the first channel 120, the second channel 130, and the third channel 133 are also opened on the shell. In this way, for the installation of the device module 109, that is, the installation of multiple sub-components such as the first sub-component 114, the second sub-component 115 and the third sub-component 132, the influence of redundant components is reduced, the complexity of the design is reduced, and because the first through hole 106 is shared, it is conducive to waterproofing and dustproofing. In some cases, since the first sub-component 114 and the second sub-component 115 are directly mounted on the shell, the size of the sub-components can be appropriately relaxed. For example, a larger microphone can be used. A larger microphone can improve the sensitivity and frequency response range of the microphone and capture more sound signals. At the same time, combined with the first through hole 106 with a smaller aperture, when using a microphone for recording, it helps to reduce the interference of environmental noise on the recording and improve the signal-to-noise ratio of the recording.
