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

[0003] In recent years, wearable electronic devices (hereinafter referred to as wearable devices), such as smart watches, smart bracelets, etc., have gradually emerged. They can be worn on the body to provide various functions and services. By connecting with devices such as smart phones, 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 and manage exercise, provide notifications and navigation functions in work and life, and improve efficiency and convenience. They have become an integral part of people's daily lives, providing personalized services and experiences for users. Wearable devices have some functional devices built-in, such as microphones, barometers, etc. These devices need to have through holes on the shell of the wearable device to communicate with the outside world. When the through holes are on the middle frame of the shell, they are easily observed by the user. When the number of through holes increases, it increases the risk of moisture entering the shell, affects the waterproof performance of the watch, and also increases the risk of dust and dirt accumulating inside the shell. SUMMARY

[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 increases the risk of moisture entering the shell, and also increases the risk of dust and dirt accumulating inside the shell.

[0005] The technical solution is as follows:

[0006] The first aspect of the present application provides a functional module applied to a wearable device, which comprises a shell and a device module.

[0007] The shell has a first side and a second side. The first side has a first mounting slot and a second mounting slot. The shell has a first through hole. The first mounting slot is in communication with the first through hole, and the second mounting slot is in communication with the first through hole. The aperture of the first through hole is located on the second side.

[0008] The device module includes a first sub-device and a second sub-device. The first sub-device is mounted in the first mounting slot, and the second sub-device is mounted in the second mounting slot.

[0009] By adopting the above scheme, the first mounting groove and the second mounting groove for mounting the first sub-device and the second sub-device are directly formed on the shell, which can simplify the number of parts of the functional module, optimize the functional module, reduce the complexity, and reduce the assembly difficulty in the first aspect, and can make the overall size of the functional module smaller, save space in the second aspect, and improve the stability and reliability of the functional module in the third aspect, and the sealing performance can be better controlled. After the first mounting groove and the second mounting groove are formed on the shell, the first through hole on the shell is matched, so that different sub-devices 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, and then reducing the risk of water entering and the risk of dust and dirt entering the shell and accumulating.

[0010] In some implementations, the first side and the second side are oppositely arranged, the first side is located on the inner side of the shell, and the second side is located on the outer side of the shell.

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

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

[0013] In some implementations, the second mounting groove is directly connected with the first through hole.

[0014] The first hole channel is a groove structure, and the groove structure is located on the groove bottom of the first mounting groove, and part of the groove wall of the groove structure is flush with part of the groove wall of the first mounting groove.

[0015] By adopting the above scheme, the second mounting groove is directly connected with the first through hole to shorten the distance between the second sub-device installed in the second mounting groove and the outside, and ensure the stability of the performance of the sub-devices 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 aperture of the first through hole on the second side can be as small as possible, and the distance between the first sub-device installed in the first mounting groove and the outside is shortened, and the stability of the performance of the sub-devices in the device module is ensured.

[0016] In some implementations, the functional module further comprises a first support and a first sealing ring, the first sub-device is installed in the first installation slot through the first support, and the first sealing ring is installed between the first support and the first installation slot in a manner of interference fit.

[0017] By adopting the above scheme, the first support can support the installation of the sub-device of the device module, and the first sealing ring can ensure the sealing performance of the first sub-device after being installed in the first installation slot.

[0018] In some implementations, the first support comprises a bottom plate portion and an enclosing portion connected to the bottom plate portion, and the enclosing portion is arranged around the circumference of the bottom plate portion.

[0019] The bottom plate portion is provided with a communication hole, and the communication hole is in communication with the first hole channel.

[0020] By adopting the above scheme, the enclosing portion and the bottom plate portion can form an installation cavity, so as to facilitate the installation of the first sub-device.

[0021] In some implementations, the shell further has a second hole channel, and the second installation slot is in communication with the first through hole through the second hole channel.

[0022] By adopting the above scheme, the second hole channel in communication with the second installation slot is also arranged on the shell, which is conducive to reducing the complexity of the functional module.

[0023] In some implementations, the first side surface is further provided with a third installation slot in communication with the first through hole, the third installation slot is located between the first installation slot and the second installation slot, the device module further comprises a third sub-device, and the third sub-device is installed in the third installation slot.

[0024] By adopting the above scheme, more sub-devices can be installed on the shell, and more sub-devices can share the first through hole, so as to reduce the number of holes observed from the outside of the shell.

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

[0026] By adopting the above scheme, the first through hole, the first hole channel and the second hole channel are integrally formed to form a fluid channel, instead of being formed by assembly of the functional module. Such an integrally formed design helps to ensure the stability and sealing performance of the fluid channel, improves 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-device and the second sub-device is a microphone, and the other is a barometer.

[0028] By adopting the above scheme, the microphone and the barometer share one first through hole, which can improve the aesthetics of the wearable device, improve the space utilization, achieve the purpose of simple and compact design, and help improve the dustproof and waterproof capability of the wearable device.

[0029] In some implementations, the aperture of the first through hole at the second side is circular.

[0030] Or, the aperture of the first through hole at the second side is in a strip shape.

[0031] By adopting the above scheme, when the first hole and the first through hole are machined from the second side of the shell, the aperture of the first through hole at the second side is in a strip shape due to the machining process, which can facilitate the machining of the first hole and the first through hole. When the first hole, the second hole and the first through hole are machined from the first side and the second side of the shell, the aperture of the first through hole at the second side is circular, which can reduce the aperture and thus facilitate dustproof and waterproof.

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

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

[0034] By adopting the above scheme, the stability of the installation of the device module can be achieved by using the pressing 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 scheme, regardless of whether the shell is a middle frame or a bottom shell, by sharing one first through hole by multiple sub-devices, the number of middle frames can be reduced; and the material of the middle frame can be set as needed.

[0037] The second aspect of the present application provides a shell manufacturing method for manufacturing the shell in any of the above functional modules.

[0041] By adopting the above scheme, the first mounting groove and the second mounting groove for mounting the first sub-device and the second sub-device are directly formed on the shell, which can simplify the number of parts of the functional module, optimize the functional module, reduce the complexity, and reduce the assembly difficulty, and can make the overall size of the functional module smaller, save space, and improve the stability and reliability of the functional module, and the sealing performance can be better controlled. After the first mounting groove and the second mounting groove are formed on the shell, the first through hole on the shell is matched, so that different sub-devices 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, and the risk of water entering and the risk of dust and dirt entering the shell and accumulating are reduced.

[0042] In some implementations, the first through hole is formed on the semi-finished product, including:

[0043] The first through hole is machined from the second side of the semi-finished product, and the first through hole is machined on the second side to communicate with the second mounting groove;

[0044] The shell manufacturing method further includes: forming a first hole channel on the bottom of the first through hole to communicate the first hole channel with the first mounting groove;

[0051] When the first through hole is machined, the hole opening of the first through hole on the second side is in a circular shape.

[0052] By adopting the above scheme, the first hole channel, the second hole channel, and the first through hole are machined from the first side and the second side of the shell, so that the hole opening of the first through hole on the second side is in a circular shape, which can reduce the hole diameter, thereby facilitating dust and water prevention.

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

[0054] processing from the first side of the semi-finished product to form the first hole in the first mounting slot;

[0055] opening the first through hole on the semi-finished product, including:

[0056] processing from the second side of the semi-finished product to form the first through hole on the second side, so that the first through hole communicates with the first hole and directly communicates with the second mounting slot;

[0057] wherein, when the first through hole is processed, the aperture of the first through hole on the second side is circular.

[0058] By using the above scheme, the aperture of the first through hole on the second side is circular, which can reduce the hole diameter and thus facilitate dust and water prevention.

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

[0060] processing from the first side of the semi-finished product to form the third mounting slot;

[0061] Before opening the first through hole on the semi-finished product, the shell manufacturing method further includes processing from the second side of the semi-finished product to form the first hole, the second hole and the third hole, so that the first hole, the second hole and the third hole respectively correspond to the first mounting slot, the second mounting slot and the third mounting slot.

In addition, in order to clearly describe the technical solutions of the present application, the same items or similar items with basically the same function and role are distinguished by using "first", "second", etc. The skilled in the art can understand that "first", "second", etc. do not limit the quantity and execution order, and "first", "second", etc. also do not limit the difference.

[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, provide various functions and services, and because they have strong jewelry attributes, creating better product appearance and improving aesthetics is an important factor to improve product competitiveness. For wearable devices, some functional devices are built in, such as microphones, barometers, etc. These devices need to open through holes on the shell of the wearable device to facilitate communication with the outside world, and when the through hole is opened on the middle frame of the shell, it is easy to be observed by the user, and when the number of through holes increases, it will increase the risk of moisture entering the inside of the shell, affect the waterproof performance of the watch, and also increase the risk of dust and dirt accumulating inside the shell. Therefore, 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 by the embodiments of the present application are explained and described in detail below.

[0090] FIG. 1 is a structural schematic diagram of a wearable device according to an embodiment of the present application. As shown in FIG. 1, in one or more embodiments, the wearable device can be worn on the body of a user, for example, can be worn on the arm, wrist, neck, finger or head, etc. The wearable device includes a housing 101, a fixing band 102 and a display screen 103. The fixing band 102 is connected to the housing 101, and the fixing band 102 realizes wearing the wearable device on the body of the user. The fixing band 102 is connected to the housing 101, and the connection mode between the fixing band 102 and the housing 101 can be detachable connection. The display screen 103 is installed on the housing 101. The housing 101 can also be installed with necessary components of the wearable device, for example, a mainboard (not shown) etc. The mainboard can have a controller to control the display screen 103. The specific type of the wearable device is not limited in the embodiments of the present application, for example, the wearable device can be an arm ring, a smart watch, a ring, a necklace, a sports bracelet, a sports watch, a health bracelet, etc. For example, the wearable device is a watch in the embodiments of the present application.

[0091] As shown in FIG. 1, in some embodiments, the housing 101 can be rectangular, in which case the watch 100 can be referred to as a square watch, of course, in some other cases, the housing 101 can also be other shapes, for example, circular. And the fixing band 102 can be a watchband.

[0092] For ease of description, as shown in FIG. 1, the length direction of the wearable device can be defined as A-A direction, the width direction of the wearable device can be defined as B-B direction, and the thickness direction of the wearable device can be defined as C-C direction. The A-A direction, the B-B direction and the C-C direction are perpendicular to each other to form a rectangular coordinate system.

[0093] FIG. 2 is a structural schematic diagram of the wearable device without the fixing band 102 according to an embodiment of the present application. As shown in FIG. 2, 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 C-C direction. For example, as shown in FIG. 2, the middle frame 104 has a first through hole 106. From the outside of the wearable device, the aperture of the first through hole 106 is in the shape of a long strip, for example, the aperture is in the shape of a waist circle, which is mainly composed of two straight lines and two arc lines. The two straight lines are parallel and have equal lengths, and the two ends of the arc lines are respectively connected to the end portions of the two straight lines. Of course, the aperture of the first through hole 106 can also be in other shapes, for example, rectangular or elliptical, etc.

[0094] Figure 3 is a sectional view along line D-D in Figure 2. Referring to Figure 3, in some embodiments, the wearable device includes a speaker 107 mounted on one side of the wearable device in the width direction, through which sound can be played; and the speaker 107 is electrically connected to the mainboard.

[0095] In some examples, the wearable device further includes a functional module 108, which includes a housing and a device module 109 mounted on the housing; the housing can be the middle frame 104 or the bottom shell 105; and the device module 109 is electrically connected to the mainboard. For example, referring to Figure 3, the housing is taken as the middle frame 104 for illustration; in Figure 3, 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 shell 105.

[0096] Figure 4 is a partial enlarged view of E in Figure 3. In combination with Figures 3 and 4, in some embodiments, the housing has a first side 110 and a second side 111, the first side 110 is provided with a first mounting groove 112 and a second mounting groove 113, and the housing is provided with a first through hole 106, i.e., the middle frame 104 has a first side 110 and a second side 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 in communication with the first through hole 106, and the second mounting groove 113 is in communication with the first through hole 106; an aperture of the first through hole 106 is located on the second side 111; the device module 109 includes a first sub-device 114 and a second sub-device 115, the first sub-device 114 is mounted in the first mounting groove 112, and the second sub-device 115 is mounted in the second mounting groove 113. In at least one embodiment, a plurality of mounting grooves for mounting a plurality of sub-devices are directly provided on the housing, i.e., the first mounting groove 112 and the second mounting groove 113 for mounting the first sub-device 114 and the second sub-device 115 are directly provided on the housing. 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 assembly difficulty; on the other hand, it is conducive to making the overall size of the functional module 108 smaller, saving space; and 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 groove 112 and the second mounting groove 113 are provided on the housing, the first through hole 106 on the housing is matched, so that different sub-devices 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, and reducing the risk of water entering and the risk of dust and dirt entering and accumulating in the housing.

[0097] In combination with FIG. 3 and FIG. 4, in some embodiments, the other aperture of the first through hole 106 is communicated with the first mounting groove 112 and the second mounting groove 113 respectively; the first sub-device 114 and the second sub-device 115 are arranged side by side along the length direction of the wearable device, and there is no screw 119 or other fastener between the first sub-device 114 and the second sub-device 115, so that the distance between the first sub-device 114 and the second sub-device 115 can be as small as possible, thereby facilitating the reduction of the area of the aperture of the first through hole 106 observed from the outside of the wearable device, so as to reduce the risk of water entering and the risk of dust and dirt entering and accumulating in the shell. For example, in combination with FIG. 3 and FIG. 4, the first sub-device 114 is a microphone, the second sub-device 115 is a barometer, and the first mounting groove 112 further has a sealing assembly 116 mounted therein, and the first sub-device 114 is mounted in the first mounting groove 112 through the sealing assembly 116. The sealing assembly 116 can include a foam layer and a waterproof sound-permeable film arranged in layers, and can prevent water from entering the interior of the microphone from the sound pickup hole of the microphone. The barometer is sleeved with a second sealing ring 117, and the second sealing ring 117 is in interference fit between the barometer and the groove wall of the second mounting groove 113, so as to avoid water or dust from entering the interior of 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 groove wall of the second mounting groove 113 can have an annular boss, which limits the second sealing ring 117 and ensures that the second sealing ring 117 cannot be displaced in the second mounting groove 113, and can improve the sealing performance.

[0098] In combination with FIG. 3 and FIG. 4, in some embodiments, the functional module 108 further includes a pressing plate 118, which is fixedly connected with the shell through the screw 119, i.e., the pressing plate 118 is fixedly connected with the middle frame 104. The screw 119 is located at both ends of the length direction of the pressing plate 118, and the first sub-device 114 and the second sub-device 115 are located between the two ends of the length direction of the pressing plate 118, and the first sub-device 114 and the second sub-device 115 are tightly mounted on the shell through the pressing plate 118. It should be noted that the pressing plate 118 is not limited to being fixedly connected with the shell through the screw 119, but can also be fixedly connected with the shell in other ways, such as being fixedly connected with the shell through a clamping manner.

[0099] Referring to FIG. 4, in some embodiments, the first side 110 is located at the inner side of the shell, and the second side 111 is located at the outer side of the shell. The shell further has a first hole 120, and the first mounting groove 112 and the first through hole 106 are connected through the first hole 120. In this way, the first hole 120 connected with 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 arranged at the inner side of the shell, and an aperture of the first through hole 106 is located at the outer side of the shell opposite to the inner side, which is conducive to reducing the connection paths between the first mounting groove 112 and the second mounting groove 113 and the first through hole 106, and can ensure the stability of the functions of each sub-device of the device module 109 while reducing the number of holes observed from the outside of the shell. For example, referring to FIG. 4, the first side 110 is the inner side of the middle frame 104, and the second side 111 is the outer side of the middle frame 104. Since the shell can be the middle frame 104, the first hole 120 is located on the middle frame 104. In the length direction of the wearable device, i.e., the A-A direction, the first mounting groove 112 and the second mounting groove 113 are arranged in a staggered manner with the first hole 120, so that when the user inserts a rod-shaped object, such as a needle, into the first through hole 106, the sub-device can be prevented from being punctured. In addition, the first hole 120 and the first through hole 106 have an included angle between the axial direction of the first hole 120 and the axial direction of the first through hole 106, i.e., are arranged in a non-parallel manner, which can further prevent puncture and can prevent water and dust. The axial direction of the first through hole 106 is parallel to the B-B direction.

[0100] In some embodiments, referring to FIG. 4, the aperture of the first through hole 106 located at the second side 111 is in a strip shape. The first hole 120 and the first through hole 106 in FIG. 4 are mainly formed by machining from the second side 111 of the shell. Due to the machining process, the aperture of the first through hole 106 located at the second side 111 in FIG. 4 is in a strip shape, which can facilitate the machining of the first hole 120 and the first through hole 106. In addition, the first hole 120 and the first through hole 106 can be machined by using a taper shank drill bit or a straight shank drill bit, which can be determined according to actual needs.

[0101] Figure 5 is a structural schematic diagram of the middle frame 104 of the wearable device provided by the embodiments of the present application, and Figure 6 is a partial enlarged schematic diagram at F in Figure 5. In combination with Figures 5 and 6, in some embodiments, the second mounting groove 113 is directly communicated with the first through hole 106, the groove wall of the second mounting groove 113 has an opening 123, so that the second mounting groove 113 is directly communicated with the first through hole 106 through the opening 123, so as to facilitate the processing of the first through hole 106 to reduce the area of the aperture of the first through hole 106. For example, the second mounting groove 113 and the first mounting groove 112 in Figures 5 and 6 are suitable for the mounting of the first sub-device 114 and the second sub-device 115 in Figures 3 and 4.

[0102] Figure 7 is another structural schematic diagram of the wearable device without the fixing band 102 provided by the embodiments of the present application. As shown in Figure 7, the aperture of the first through hole 106 on the middle frame 104 is in the shape of a waist circle from the outside of the wearable device.

[0103] Figure 8 is a sectional view along the line G-G in Figure 7, and Figure 9 is a partial enlarged schematic diagram at H in Figure 8. In combination with Figures 8 and 9, the first sub-device 114 is a barometer, and the second sub-device 115 is a microphone. The barometer is sealingly fitted with the first mounting groove 112 through the second sealing ring 117, and the microphone is mounted in the second mounting groove 113 through the sealing assembly 116. The barometer and the microphone are fixedly mounted on the middle frame 104 through the pressing plate 118. The first mounting groove 112 is indirectly communicated with the first through hole 106 through the first hole channel 120, and the second mounting groove 113 is directly communicated with the first through hole 106. The axial direction of the first hole channel 120 and the axial direction of the first through hole 106 have an included angle, i.e., are non-parallel, so as to further prevent the barometer and the microphone from being poked, and to prevent water and dust, and the axial direction of the first through hole 106 is parallel to the direction of B-B. The second mounting groove 113 can be in the shape of a step, i.e., 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 the second sub-groove portion 122 is communicated 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 the barometer, the groove wall of the first mounting groove 112 can have an annular boss, which limits the second sealing ring 117 and ensures that the second sealing ring 117 cannot be displaced in the second mounting groove 113, and can improve the sealing performance. In addition, the difference between Figures 8 and 3 is mainly that the mounting positions of the microphone and the barometer are different, i.e., the microphone is mounted in the first mounting groove 112 and the barometer is mounted in the second mounting groove 113 in Figure 3; the microphone is mounted in the second mounting groove 113 and the barometer is mounted in the first mounting groove 112 in Figure 8.

[0105] In some embodiments, referring to FIG. 9, the opening of the first through hole 106 on the second side 111 is in a strip shape. The first through hole 106 and the first hole 120 in FIG. 9 are mainly formed by machining from the second side 111 of the shell. Due to the machining process, the opening of the first through hole 106 on the second side 111 in FIG. 9 is in a strip shape, which can facilitate the machining of the first through hole 106 and the first hole 120.

[0106] FIG. 10 is a structural schematic diagram of a middle frame 104 of a wearable device provided in the embodiments of the present application; and FIG. 11 is a partial enlarged schematic diagram of J in FIG. 10. In combination with FIG. 10 and FIG. 11, in some embodiments, the groove bottom and the groove wall of the second mounting groove 113 have an opening 123, i.e., the opening 123 is formed on the groove bottom and the groove wall, so that the first through hole 106 directly communicates with the opening 123, which facilitates the machining of the first through hole 106 and reduces the area of the opening of the first through hole 106. For example, the second mounting groove 113 and the first mounting groove 112 in FIG. 10 and FIG. 11 are suitable for the mounting of the first sub-device 114 and the second sub-device 115 in FIG. 8 and FIG. 9.

[0107] Figure 12 is a schematic diagram of a partial structure of the functional module 108 according to an embodiment of the present application; only a partial structure of the shell is shown in Figure 12; Figure 13 is a sectional view along line K-K in Figure 12; Figure 14 is a schematic diagram of a partial structure of the shell according to an embodiment of the present application; the shell shown in Figure 14 is the shell of the functional module 108 in Figure 12; in combination with Figures 12 and 13, in some embodiments, the second mounting groove 113 is directly communicated with the first through hole 106; the first hole channel 120 is a groove structure, which is located at the groove bottom of the first mounting groove 112; 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 second mounting groove 113 is directly communicated with the first through hole 106, so as to shorten the distance between the second sub-device 115 mounted in the second mounting groove 113 and the outside, and ensure the stability of the performance of the sub-devices 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 opening of the first through hole 106 on the second side surface 111 can be as small as possible, and the distance between the first sub-device 114 mounted in the first mounting groove 112 and the outside is shortened, so as to ensure the stability of the performance of the sub-devices in the device module 109. For example, in combination with Figures 13 and 14, the first sub-device 114 is a microphone, and the second sub-device 115 is a barometer; the barometer is in interference fit with the second mounting groove 113 through the second sealing ring 117, and the microphone is mounted in the first mounting groove 112 through the sealing assembly 116; the groove bottom and the groove wall of the second mounting groove 113 have an opening 123, i.e., the opening 123 is formed on the groove bottom and the groove wall, so that the opening 123 is directly communicated with the first through hole 106, which is easy for processing the first through hole 106 to reduce the area of the hole opening of the first through hole 106; the first hole channel 120 is in the shape of a long strip; one end of the first hole channel 120 is located at the center of the groove bottom of the first mounting groove 112, and the other end of the first hole channel 120 is located at the groove wall of the first mounting groove 112; the first hole channel 120 is communicated with the first through hole 106, so that the first mounting groove 112 is indirectly communicated with the first through hole 106 through the first hole channel 120.

[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, which can be completely flush or approximately flush. In addition, in some other possible embodiments, the first through hole 106 can be directly communicated with the first mounting groove 112 and the second mounting groove 113, respectively.

[0109] In combination with FIGS. 13 and 14, in some embodiments, the functional module 108 further comprises a first bracket 124 and a first sealing ring 125, the first sub-device 114 is installed in the first installation slot 112 through the first bracket 124, and the first sealing ring 125 is installed between the first bracket 124 and the first installation slot 112 through interference fit. Since the other end of the first hole 120 is located at the slot wall of the first installation slot 112, and the first hole 120 is located at the slot bottom of the first installation slot 112, the first hole 120 causes a notch in the form of a recess at the slot bottom of the first installation slot 112. The edge of the bottom of the sealing assembly 116 can be supported by the first bracket 124 to ensure the performance of the sealing assembly 116, and the first sealing ring 125 is used to ensure the sealing performance of the first sub-device 114 after being installed in the first installation slot 112.

[0110] In combination with FIGS. 13 and 14, in some embodiments, the first bracket 124 comprises a bottom plate part 126 and an enclosing part 127 connected to the bottom plate part 126, and the enclosing part 127 is arranged around the circumference of the bottom plate part 126. The bottom plate part 126 has a through hole 128, and the through hole 128 is in communication with the first hole 120. Thus, the enclosing part 127 and the bottom plate part 126 can form an installation cavity to facilitate the installation of the first sub-device 114. For example, the bottom plate part 126 is circular, the through hole 128 is located at the center of the bottom plate part 126, and the bottom plate part 126 can support the circumference of the bottom of the sealing assembly 116. The enclosing part 127 is in the form of a barrel, and the bottom plate part 126 is arranged perpendicularly to the enclosing part 127. The first bracket 124 further comprises a rim part 129 connected to the enclosing part 127, and the bottom plate part 126 and the rim part 129 are respectively located at two ends of the height direction of the barrel-shaped enclosing part 127. The height direction of the enclosing part 127 is parallel to the B-B direction, and the rim part 129 extends towards the slot wall of the first installation slot 112. In the case of interference fit, the first sealing ring 125 will be deformed, and the rim part 129 can further ensure the waterproof and dustproof effects.

[0111] In combination with FIGS. 13 and 14, in some embodiments, the aperture of the first through hole 106 located at the second side 111 is circular. The first hole 120 and the first through hole 106 in FIGS. 13 and 14 are mainly formed by machining from the first side 110 and the second side 111 of the shell. Thus, the aperture of the first through hole 106 located at the second side 111 can be circular, thereby reducing the aperture and facilitating dustproof and waterproof effects. In addition, the first hole 120 and the first through hole 106 can be machined by using a taper shank drill bit or a straight shank drill bit. The specific machining method can be determined according to actual needs.

[0112] Fig. 15 is a partial structural schematic view of another functional module 108 according to an embodiment of the present application; Fig. 16 is a partial structural schematic view of another functional module 108 according to an embodiment of the present application; as shown in Figs. 15 and 16, the shell further has a second hole 130, the second mounting slot 113 and the first through hole 106 are connected through the second hole 130, so that the second hole 130 connected with the second mounting slot 113 is also arranged on the shell, which is conducive to reducing the complexity of the functional module 108. For example, in Figs. 15 and 16, the first mounting slot 112 is indirectly connected with the first through hole 106 through the first hole 120, the second mounting slot 113 is indirectly connected with the first through hole 106 through the second hole 130, the first sub-device 114 is a microphone, and the second sub-device 115 is a barometer. It should be noted that the difference between Figs. 15 and 16 mainly lies in that, in Fig. 15, the first hole 120, the second hole 130, and the first through hole 106 are mainly machined by using a straight shank drill bit, and in Fig. 16, the first hole 120, the second hole 130, and the first through hole 106 are mainly machined by using a taper shank drill bit; compared with using a straight shank drill bit, using a taper shank drill bit is conducive to obtaining larger first hole 120 and second hole 130, thereby improving the permeability.

[0113] As shown in Figs. 15 and 16, in some embodiments, the first hole 120 has an angle between the axial direction and the axial direction of the first through hole 106, and the second hole 130 has an angle between the axial direction and the axial direction of the first through hole 106, that is, the first hole 120 and the second hole 130 are arranged in a non-parallel manner, which can further prevent the functional module 108 from being poked and can prevent water and dust. In the B-B direction, the distance between the barometer and the hole of the first through hole 106 on the second side 111 is less than the distance between the microphone and the hole of the first through hole 106 on the second side 111, which is conducive to improving the sensitivity of the barometer and ensuring its performance.

[0114] As shown in Figs. 15 and 16, the hole of the first through hole 106 on the second side 111 is circular, and the first hole 120, the second hole 130, and the first through hole 106 in Figs. 15 and 16 are mainly formed by machining from the first side 110 and the second side 111 of the shell; using this machining method can make the hole of the first through hole 106 on the second side 111 circular, which can reduce the aperture, thereby being conducive to preventing dust and water.

[0115] In some embodiments, the first through hole 106, the first hole channel 120 and the second hole channel 130 are integrally formed, so that the first through hole 106, the first hole channel 120 and the second hole channel 130 are integrally formed to form the fluid channel, rather than being formed by assembling the functional module 108. Such an integrally formed design helps to 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 FIGS. 15 and 16, the first through hole 106, the first hole channel 120 and the second hole channel 130 are integrally formed.

[0116] FIG. 17 is a partial structural schematic view of another functional module 108 according to an embodiment of the present application. Referring to FIG. 17, the first side surface 110 further has a third mounting slot 131 that is in communication with the first through hole 106. In the length direction of the wearable device, the third mounting slot 131 is located between the first mounting slot 112 and the second mounting slot 113. The device module further includes a third sub-device 132. The third sub-device 132 is mounted in the third mounting slot 131. In this way, more sub-devices can be mounted on the housing, i.e., more sub-devices are mounted on the middle frame, so that more sub-devices share the first through hole 106, thereby reducing the number of holes observed from the outside of the housing. For example, the first mounting slot 112 is indirectly in communication with the first through hole 106 through the first hole channel 120, the second mounting slot 113 is indirectly in communication with the first through hole 106 through the second hole channel 130, the first sub-device 114 is a microphone, the second sub-device 115 is a barometer, and the third sub-device 132 can be a balance valve (also referred to as a waterproof and breathable membrane assembly). The housing further has a third hole channel 133, and the third mounting slot 131 is indirectly in communication with the first through hole through the third hole channel 133.

[0117] It should be noted that the number of mounting slots on the first side surface 110 and the number of sub-devices in the device module 109 can be one-to-one, i.e., one sub-device is mounted in one mounting slot. Of course, in some other cases, the number of mounting slots and the number of sub-devices can not be one-to-one, e.g., multiple sub-devices, such as two or three, can be mounted in one mounting slot. Furthermore, the number of mounting slots in the first side surface 110 can not be two, and the first side surface 110 can further have a fourth mounting slot. The number of sub-devices in the device module 109 can not be two or three, and the device module 109 can further include a fourth sub-device mounted in the fourth mounting slot.

[0118] Referring to FIG. 17, in some embodiments, the first hole 120 has an angle with the axial direction of the first through hole 106, the second hole 130 has an angle with the axial direction of the first through hole 106, and the third hole 133 has an angle with the axial direction of the first through hole 106, that is, the first hole 120, the second hole 130, and the third hole 133 are arranged in a non-parallel manner, which can further prevent the first hole 120, the second hole 130, and the third hole 133 from being poked, and can prevent water and dust. The first through hole 106, the first hole 120, the second hole 130, and the third hole 133 are integrally formed, that is, the first through hole 106, the first hole 120, the second hole 130, and the third hole 133 are integrally formed to form a fluid channel, rather than being formed by assembling the functional module 108. Such an integrally formed design helps to ensure the stability and sealing of the fluid channel, and also improves the overall performance and reliability of the functional module 108, and is conducive to 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, can be 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, can be 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 shell is the middle frame 104 or the bottom shell 105; wherein the material of the middle frame 104 is metal, or the material of the middle frame 104 is plastic, or the material of the middle frame 104 includes metal and plastic, so that no matter whether the shell is the middle frame 104 or the bottom shell 105, by sharing one first through hole 106 by multiple sub-devices, the number of middle frames 104 can be reduced; and the material of the middle frame 104 can be set as needed. It should be noted that when the material of the middle frame 104 includes metal and plastic, the middle frame 104 can adopt an integrated structure formed by insert injection molding of metal and plastic.

[0121] It should be noted that in some other possible embodiments, a hydrophobic coating can be provided on the inner wall of the first hole 120; a hydrophobic coating can be provided on the inner wall of the second hole 130; and a hydrophobic coating can be provided on the inner wall of the first through hole 106. The hydrophobic coating can be a fluorocarbon coating or a siloxane hydrophobic coating, which is conducive to realizing the waterproof function.

[0122] In one or more embodiments, the present application also provides a shell manufacturing method for manufacturing the shell in the functional module 108 in any embodiment of the present application;

[0123] The shell manufacturing method comprises: machining from a first side 110 of a semi-finished product to machine a first mounting groove 112 and a second mounting groove 113; and opening a first through hole 106 in the semi-finished product to form a shell from the semi-finished product, wherein the first through hole 106 is communicated to the first mounting groove 112, the first through hole 106 is also communicated to the second mounting groove 113, and an aperture of the first through hole 106 is located on a second side 111 of the semi-finished product. The shell manufacturing method in the embodiment of the application directly opens the first mounting groove 112 and the second mounting groove 113 for mounting the first sub-device 114 and the second sub-device 115 on the shell, which can simplify the number of parts of the functional module 108, optimize the functional module 108, reduce complexity, and reduce assembly difficulty in the first aspect, is conducive to making the overall size of the functional module 108 smaller, saving space in the second aspect, and is conducive to improving the stability and reliability of the functional module 108 and better controlling the sealing performance in the third aspect. 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 further opened, so that different sub-devices 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, and in turn reducing the risk of water entering and the risk of dust and dirt entering and accumulating in the shell.

[0124] In some embodiments, the method of opening the first through hole 106 on the semi-finished product comprises: machining from the second side 111 of the semi-finished product to machine the first through hole 106 on the second side 111, so that the first through hole 106 is directly communicated to the second mounting groove 113. The shell manufacturing method further comprises: opening a first channel 120 on the bottom of the first through hole 106, so that the first channel 120 is communicated to the first mounting groove 112; wherein, after the first channel 120 is machined, the aperture of the first through hole 106 on the second side 111 is in a strip shape; in this way, when the first channel 120 and the first through hole 106 are machined from the second side 111 of the shell, the aperture of the first through hole 106 on the second side 111 is in a strip shape due to the machining process, so that the first channel 120 and the first through hole 106 can be machined more conveniently. For example, the first through hole 106 and the first channel 120 of the shell of the functional module 108 in FIGS. 4 and 9 can be implemented by using this method.

[0125] In some other embodiments, the shell manufacturing method further comprises: machining from the first side 110 of the semi-finished product, machining the first hole passage 120 in the first mounting groove 112. The method for machining the first through hole 106 on the semi-finished product comprises: machining from the second side 111 of the semi-finished product, machining the first through hole 106 on the second side 111, connecting the first through hole 106 with the first hole passage 120, and directly connecting the first through hole 106 with the second mounting groove 113; wherein, when 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. In this way, machining from the first side 110 and the second side 111 of the shell to machine the first hole passage 120 and the first through hole 106 can make the opening of the first through hole 106 on the second side 111 circular, which can reduce the aperture and thus facilitate dust and water prevention. Exemplarily, the first through hole 106 of the shell of the functional module 108 in FIG. 14 can be implemented by using this method.

[0126] In some other embodiments, the shell manufacturing method further comprises: machining from the first side 110 of the semi-finished product, machining the first hole passage 120 in the first mounting groove 112, and machining the second hole passage 130 in the second mounting groove 113.

In this way, machining from the first side 110 and the second side 111 of the shell to machine the first hole passage 120, the second hole passage 130 and the first through hole 106 can make the opening of the first through hole 106 on the second side 111 circular, which can reduce the aperture and thus facilitate dust and water prevention. Exemplarily, the first through hole 106, the first hole passage 120 and the second hole passage 130 of the shell of the functional module 108 in FIGS. 15 and 16 can be implemented by using this method.

[0129] Step S102, processing from the first side surface 110 of the semi-finished product, using the straight shank drill bit 201 to drill the first hole channel 120 and the second hole channel 130 in the first mounting groove 112 and the second mounting groove 113 respectively, which are inclined to the B-B direction, the processing process of the first hole channel 120 and the second hole channel 130 is shown in (b) of FIG. 18, and (c) of FIG. 18 shows that the first hole channel 120 and the second hole channel 130 are formed after processing is completed;
