[0001] This application claims priority to a patent application filed with the Patent Office of China on June 16, 2023, with application number 202310731774.0 and application name “Wearable device band, manufacturing method thereof, 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 related to smart wearable devices, and in particular to a wearable device belt, a manufacturing method thereof, and a wearable device. Background Art

[0003] With the development of Internet technology and intelligent products, various intelligent wearable products have appeared on the market. Among them, smart watches, as a common intelligent wearable product, have brought convenience to users.

[0004] In addition to standard watch functions, existing smartwatch dials can also incorporate health monitoring and activity tracking features, such as blood pressure and calorie consumption monitoring. Straps are primarily used to wear and secure smartwatches. As smartwatch functionality diversifies, limited space within the dial creates a challenge for the industry in integrating more functionality into wearable products like smartwatches.

[0005] Summary of the Invention

[0006] The present application provides a wearable device band and a manufacturing method thereof, wherein the band can accommodate functional components to solve the technical problem of limited space within a dial.

[0007] The present application also provides a wearable device.

[0008] The present application provides a wearable device band, the band comprising a body, functional components, a circuit board, and a protective shell, the protective shell comprising a bracket and a transparent cover, the protective shell comprising a cavity, the circuit board being completely embedded in the body, the bracket of the protective shell being embedded in the body, the bracket being connected to a surface of the circuit board in a thickness direction of the body, the transparent cover being connected to a side of the bracket away from the circuit board, and the transparent cover being exposed from the surface of the body;

[0009] The functional device is mounted on the surface of the circuit board and sealed in the cavity. The functional device can be electrically connected to the wearable device, and the signal of the functional device can pass through the transparent cover and be transmitted out of the body.

[0010] The wearable device of the present application is a smartwatch, which houses functional devices within its body, freeing up space on the dial and saving dial space. This can also be understood as the functional devices within the body adding some functions to the watch's original smart functions, such as expanding the scope of use of the smartwatch. Furthermore, the bracket of the present application is embedded in the body, improving the sealing performance of the joint surface and simplifying the processing technology. The functional device is encapsulated in the cavity of the bracket, providing support and enclosure for the device, isolating the body and the functional device, and preventing the functional device from being damaged by external forces. Furthermore, the bracket can support the transparent cover to ensure that optical path performance is provided for the functional device.

[0011] In one embodiment, the body, the circuit board, and the bracket are integrally formed. In this embodiment, the integrally formed part is formed by placing the circuit board and the bracket into a mold, and then injection molding the body within the mold. The body then encases the circuit board and the bracket. This ensures waterproof performance at the interface between the body, the circuit board, and the bracket.

[0012] In one embodiment, the bracket and the surface of the circuit board are connected and fixed by an adhesive layer; or the bracket and the circuit board are integrally formed. The bracket is connected to the circuit board via an adhesive layer, which facilitates the disassembly and position adjustment of the bracket. The bracket and the circuit board are integrally formed, which saves the adhesive layer and reduces the overall thickness. The integrally formed part of this embodiment refers to placing the circuit board into a mold, and the bracket is formed by injection molding in the mold, with one side of the bracket connected to the surface of the circuit board.

[0013] In one embodiment, the bracket encloses the cavity, which has an opening facing away from the circuit board, exposing the surface of the body, and the transparent cover seals the opening. In this embodiment, the transparent cover is separate from the bracket, facilitating removal of functional components within the cavity for maintenance.

[0014] In one embodiment, a bearing platform is provided on the inner peripheral side of the bracket, the bearing platform faces the opening, and the transparent cover is sealed to the bearing platform via an adhesive layer. The adhesive layer connection can achieve better sealing performance.

[0015] In one embodiment, the transparent cover and the bracket are integrally formed by injection molding, and of the materials of the transparent cover and the bracket, at least the transparent cover is made of a light-transmitting material. In this embodiment, the transparent cover and the bracket are integrally formed by injection molding without the need for an adhesive layer, thereby reducing the thickness of the protective case, reducing the number of bonding interfaces, improving sealing performance, and simplifying the installation process.

[0016] In one embodiment, the transparent cover and the bracket form a cavity. The bracket includes a connection surface surrounding the opening of the cavity. The protective shell is mounted on the surface of the circuit board. The functional device is located within the cavity. The connection surface and the surface of the circuit board are connected and fixed by an adhesive layer. The circuit board encapsulates the opening. The opening faces the circuit board, the connection surface is connected to the circuit board, and the functional device is installed in the cavity through the opening.

[0017] In one embodiment, the transparent cover protrudes from the surface of the body. Regardless of whether the transparent cover is located on the exterior or interior side of the strap, this improves the fit of the transparent cover against the skin, allowing for better signal transmission and reception between the functional devices and the human body. When the transparent cover is located on the exterior of the strap and protrudes, the protruding transparent cover is more convenient for the user to observe and touch.

[0018] When the transparent cover is located on the outer surface of the belt body, a decorative area can be formed locally on the transparent cover, including patterns and colors, to enhance the recognition of the position of the functional components and beautify the appearance of the belt body.

[0019] In one embodiment, the joining surface between the bracket and the body is curved. Injection molding the joining surface between the bracket and the body enhances the connection strength between the two.

[0020] In one embodiment, the strap further includes a connector, which is integrally formed with the strap body and electrically connected to the circuit board, with one end of the connector protruding from the strap body. The connector is used to plug into the watch face, transmitting signals from the functional components on the circuit board to the watch face's mainboard. Directly plugging the connector into the watch face ensures both physical and electrical connections, facilitating assembly and maintenance.

[0021] In one embodiment, the body includes a bending area, which is located between the opposite ends of the body in the length direction, and the bracket is arranged closer to the connector than the bending area; or, the circuit board is a flexible circuit board, which extends along the length direction of the belt body, and the bracket is arranged farther away from the connector than the bending area.

[0022] In this embodiment, the bracket is arranged closer to the connector than the bending area, that is, adjacent to the dial. When the band is worn on the wrist, the bracket is located on the outside of the wrist (the wider side of the wrist, the same side as the dial), and will not bend to the functional device, nor will it affect the wearing comfort.

[0023] The circuit board is a flexible circuit board, and the bracket is farther away from the connector than the bending area. In this way, the bracket can be set not near the connector, but in the middle or tail of the belt. When the belt is worn on the wrist, the bracket is located on the inside of the wrist (on the same side as the palm) to avoid bending of the functional device.

[0024] The present application provides a wearable device, comprising a dial and the aforementioned strap, wherein a connector is embedded in one end of the strap, the connector being disposed adjacent to the bracket and electrically connected to the circuit board;

[0025] The strap is detachably connected to the dial, and the connector is plugged into the dial and electrically connected to the dial's circuit board. Functional components can be installed in both the strap and the dial of the wearable device of this embodiment, improving the flexibility of dial space utilization and increasing the functionality of the wearable device.

[0026] The hardness of the body is less than that of the bracket. The bracket is made of hard, high-temperature resistant plastic, and its hardness is greater than that of the body, which can better protect the body.

[0027] The present application provides a method for manufacturing a wearable device strap, the method comprising:

[0028] Fixing and electrically connecting the connector to the circuit board;

[0029] A bracket is arranged on the surface of the circuit board, wherein the bracket includes a cavity having an opening away from the surface of the circuit board,

[0030] An in-mold injection molding process is used to form a body embedded with the circuit board, the connector, and the bracket, wherein the opening of the cavity exposes the surface of the body;

[0031] The functional device is installed in the cavity and fixedly connected to the surface of the circuit board and is electrically connected;

[0032] A transparent cover plate is provided and mounted on the bracket. The transparent cover plate seals the opening of the cavity and is spaced apart from and opposite to the circuit board.

[0033] The bracket and the body of the present application are integrally formed, which improves the sealing performance of the joint surface and simplifies the processing technology. In addition, the bracket is harder than the body, which avoids deformation during the high-temperature injection molding process of the body.

[0034] In one embodiment, the step of providing a bracket on the surface of the circuit board specifically includes:

[0035] providing a stent having a cavity with an opening;

[0036] The bracket is connected to the surface of the circuit board through an adhesive layer, wherein the opening of the cavity is away from the circuit board.

[0037] In one embodiment, the “providing a bracket on the surface of the circuit board” specifically includes placing the circuit board connected with the connector into an injection mold, and forming the bracket on the surface of the circuit board by a first injection molding;

[0038] The main body with the circuit board, the connector and the bracket embedded therein is formed by adopting an in-mold injection molding process, specifically, the bracket is formed by a second in-mold injection molding after the first injection molding, thereby simplifying the processing technology.

[0039] The present application provides a method for manufacturing a wearable device strap, the method comprising:

[0040] The connector is fixedly connected and electrically connected to a circuit board, wherein the surface of the circuit board is provided with functional devices;

[0041] Injection molding forms a protective shell, the protective shell comprising a bracket and a transparent cover plate, the bracket and the transparent cover plate enclosing a cavity with an opening, the transparent cover plate being opposite to the opening;

[0042] The protective shell is connected to the surface of the circuit board, the functional device is encapsulated in the cavity, and the transparent cover is separated from the circuit board;

[0043] The circuit board, the connector and the protective shell are implanted into a mold for injection molding to form a body, and the transparent cover exposes the surface of the body.

[0044] In one embodiment, the bracket and the transparent cover are formed by double-shot injection molding.

[0045] In one embodiment, the bracket and the transparent cover are injection molded by transparent material.

[0046] In this method, the protective shell is used as an integrated structural component and then connected to the circuit board to encapsulate the functional components, thereby improving the sealing performance and simplifying the installation process. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0067] The present application provides a wearable device, which includes at least a strap. The wearable device may be a watch, smartwatch, wristband, smart bracelet, augmented reality (AR) glasses (the portion used for fixing may be an elastic flexible strap), AR helmet, virtual reality (VR) glasses, VR helmet, or medical electronic health detection equipment, etc., which are wearable electronic products connected by a strap. Among them, the strap used for watches and wristbands or medical electronic health detection equipment such as hand straps and foot straps is a watch strap, and the strap used for glasses and helmets can be called a strap or connecting strap, etc., which is used to fix the glasses and helmet to the human body.

[0068] Please refer to Figure 1, which is a schematic diagram of the structure of a wearable device 500 provided in an embodiment of the present application. The wearable device 500 of this embodiment is described using a smartwatch as an example. A smartwatch has the functions of a regular watch, as well as mobile phone functions, entertainment functions (such as audio devices), health monitoring (monitoring devices), exercise monitoring, and navigation (navigation module), and has an electronic display screen.

[0069] As shown in Figure 1, the wearable device 500 includes a band 100 (which can be called a watchband) and a dial 200. The band 100 and the dial 200 are detachably connected to each other, and are used to secure the smartwatch to the wearer's wrist. The band 100 and the dial 200 are also electrically connected. The dial 200 includes a dial body 210 and a display screen 220. The display screen 220 is mounted on the dial body 210. The display screen 220 can be set on the surface of the dial 200 or serve as the entire surface of the dial 200. The back of the smartwatch shown in the figure, and the display screen 220 are drawn with dotted lines for ease of understanding.

[0070] The display screen is used to display incoming call information, news, weather information, and other content, and synchronize phone calls, text messages, emails, photos, music, and other functions. Display screen 220 can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a quantum dot light-emitting diode (QLED) display, or other materials. Components for entertainment, health monitoring, exercise monitoring, and navigation can be located within the watch face body 210 or on the band 100.

[0071] The dial 200 also includes a processor, memory, a communication module, an antenna, a wireless charging module, and the like, and may also be provided with buttons. For example, the processor can be used to read and execute computer-readable instructions. The processor includes a controller, an arithmetic unit, and registers. The controller is primarily responsible for decoding instructions and issuing control signals for operations corresponding to the instructions. The arithmetic unit is primarily responsible for temporarily storing register operands and intermediate operation results during instruction execution. The processor can be used to parse signals received by the communication module. The memory is coupled to the processor and is used to store various software programs and / or multiple sets of instructions. The memory may include random access memory, such as a disk storage device or a flash memory device. The communication module and antenna can provide wireless communications, including WLAN (such as Wi-Fi networks), for use in the smartwatch. The various functional components described above can be electrically connected to the main circuit board, processor, communication module, etc. to perform their functions. The dial 200 and buttons can both perform certain functions in response to user operations. For example, a button can display the main interface in response to a user's finger press. In summary, the smartwatch in this application has the functions of common smartwatches, which are not listed here.

[0072] The strap 100 comprises two straps 100, each connected to opposite sides of the watch dial 200. The ends of the straps 100 facing away from the watch dial 200 can interlock to secure the smartwatch to the wearer's wrist. The two straps 100 can have the same or different appearances and structures, which are not intended to be limiting. At least one of the straps 100 houses the functional components of a smartphone, and if both straps 100 contain functional components, their functions differ.

[0073] Please refer to Figures 2, 3, and 4. Figure 2 is a schematic diagram of the structure of the wearable device band shown in Figure 1. Figure 3 is a schematic diagram of the exploded structure of the transparent cover and body 30 of the first embodiment of the band 100 shown in Figure 2. Figure 4 is a schematic diagram of the exploded structure of the band 100 of the first embodiment shown in Figure 1. For ease of description, the width of the band 100 is defined as the X-axis, the length of the band 100 is defined as the Y-axis, and the thickness of the band 100 is defined as the Z-axis. The X-axis, Y-axis, and Z-axis directions are mutually perpendicular. It should be noted that the exploded view of the various components of the band 100 in Figure 4 is intended to facilitate the following description and provide a clearer understanding of the structure of the band 100. In some embodiments, the exploded view of the various components of the band 100 in Figure 4 is not necessarily related to the assembly order and connection method of the various components.

[0074] This embodiment uses the example of a band 100 housing functional devices. Band 100 includes a circuit board 10, functional devices 15, and a connector 20. The functional devices 15 and connector 20 are electrically connected to the circuit board 10, and the connector 20 is used to plug into and electrically connect with the dial 200. The circuit board 10 can be a printed circuit board (PCB) or a flexible circuit board (FPC). The dial 200 includes a main circuit board (not shown), which is located within the dial body 210. The main circuit board is equipped with connectors or gold fingers that plug into the connector 20 to electrically connect the circuit board 10 and functional devices 15 to the main circuit board.

[0075] The functional device 15 can serve the monitoring function of the smart watch. The functional device 15 of this embodiment can be a monitoring module for monitoring human physiological parameters in order to understand the health status of the body; for example, monitoring blood pressure parameters, blood sugar parameters, body temperature parameters, heart rate parameters, blood oxygen parameters, calorie consumption, etc. The functional device 15 can be an electrocardiograph (ECG) device, a photoelectric device, a pulse sensor, a body temperature sensor, or other device or module that realizes the parameters that the functional device 15 wants to monitor. Of course, the functional device 15 can also be used for environmental monitoring in special environments and industries. In this embodiment, the functional device 15 is used to monitor health conditions, for example, the functional device 15 is a heart rate sensor. The functional device 15 may include an optical transmitting module and a receiving module to obtain the human pulse waveform when it is close to the wearer's wrist.

[0076] In other embodiments, the strap 100 of the present application may further include other functional components, such as a navigation module, an audio component, etc., without limitation in number or location, as long as they do not affect the original wearing and comfort of the strap. The smartwatch of the present application integrates some functional components into the strap, thereby increasing the diversity of smart functions of the smartwatch, making full use of the space of the strap, and allowing space for the dial, thereby increasing the flexibility of the dial design.

[0077] The belt 100 also includes a main body 30 and a protective shell 30A. The circuit board 10 and protective shell 30A are embedded in the main body 30. The functional device 15 is housed in the protective shell 30A and fixedly connected to the circuit board 10. The monitoring signal of the functional device 15 can be transmitted through the protective shell 30A. It can be understood that the functional device 15 is housed in the main body 30, or is covered by the main body 30.

[0078] The body 30 is an elongated, strip-shaped belt, comprising a first surface 31, a second surface 32, and a connecting end 33. The first and second surfaces 31, 32 are arranged in opposite directions along the thickness of the belt body 100. In one embodiment, the first surface 31 is the inner side of the belt body 100, facing the wearer when worn. The second surface 32 is the exterior surface and may be provided with aesthetically pleasing patterns. In another embodiment, the first surface 31 is the exterior surface of the belt body 100, and the second surface 32 is the inner side of the belt body 100. The exterior surface of the belt body 100 is determined by the operating mode of the functional device 15.

[0079] In this embodiment, the body 30 can be made of a flexible material, specifically, through in-mold integration; the flexible material may be liquid silicone, fluororubber, or the like. The body 30 shown includes a bending region 303 located between opposite ends of the body 30 along its length. When the band 100 is worn, the bending region 303 bends from the outside of the wrist to the inside of the wrist to accommodate the contours of the wrist. It should be noted that the bending region 303 is merely for ease of understanding the structure of the band 100 and does not necessarily represent the position and dimensions shown in the figure. Furthermore, the surface of the band 100 is not limited to the concave and convex surfaces shown in the figure; it may also be flat or otherwise curved.

[0080] The body 30 further includes a mounting slot 301 and a plugging slot 302. The mounting slot 301 is recessed from the first surface 31 toward the second surface 32, while the plugging slot 302 is recessed at the connection end 33 and communicates with the mounting slot 301. The mounting slot 301 and the plugging slot 302 are actually formed directly during the injection molding of the body 30. The mounting slot 301 accommodates the bracket 35 and the circuit board 10, with the slot walls tightly connected to the bracket 35 and the circuit board 10. The plugging slot 302 is shaped to accommodate the connector 20.

[0081] As shown in Figure 3, in the first embodiment of the present application, the protective shell 30A includes a bracket 35 and a transparent cover 36, which are fixedly connected by an adhesive layer. For ease of description, the height direction of the bracket 35 is defined as the thickness direction of the belt body 100.

[0082] The protective shell 30A has a cavity B. A bracket 35 is embedded in the body 30 and connected to the surface of the circuit board 10. The functional device 15 is housed in the cavity B and fixedly connected to the circuit board 10. A transparent cover 36 is connected to the side of the bracket 35 away from the circuit board 10, and together with the circuit board 10, it covers and encapsulates the cavity B. In this embodiment, the bracket 35 is made of a relatively hard plastic material, such as polyamide (PA). It will be understood that the material selected for the bracket 35 can maintain its shape under the molding temperature and pressure of the body 30, ensuring mechanical properties and other properties, thereby reliably protecting the functional device 15.

[0083] In one embodiment, the hardness of the bracket 35 is greater than that of the body 30. This can be understood as the melting point (softening point) of the bracket 35 material being greater than that of the body 30 material, thereby preventing the bracket 35 from completely melting during the high-temperature injection molding of the body 30. The transparent cover 36 is made of highly translucent plastic or glass, and its outer surface is highly wear-resistant. The transparent cover 36 is connected to the bracket 35 and the body 30 via an adhesive layer 37.

[0084] For more details, please refer to Figure 5, which is a schematic cross-sectional view of the bracket shown in Figure 4. The bracket 35 is a rectangular frame structure that encloses a cavity B with an opening. Cavity B has two opposing openings 350: one opening 350 is referred to as the cavity opening, and the other opening can be referred to as the mounting opening. The height of the bracket 35 corresponds to the height of the cavity, which is also the thickness of the belt body 100. The two openings 350 are located opposite each other in the height direction of the cavity. The bracket 35 also includes an inner peripheral side surface 351, an outer peripheral side surface 352, a first connecting surface 353, and a second connecting surface 354. The inner peripheral side surface 351 and the outer peripheral side surface 352 are arranged opposite each other, with the inner peripheral side surface 351 forming the surface of the cavity wall of cavity B. Along the height direction of the bracket 35, the first connecting surface 353 and the second connecting surface 354 are arranged opposite each other, and both the first connecting surface 353 and the second connecting surface 354 connect the inner peripheral side surface 351 and the outer peripheral side surface 352. The first connection surface 353 surrounds the opening of the cavity B, and the second connection surface 354 surrounds the installation port of the cavity B.

[0085] In this embodiment, the inner side surface 351 of the bracket 35 is provided with a bearing platform 356. The bearing platform 356 is a step formed by the inner side surface 351 being recessed into the bracket 35. The bearing platform 356 faces away from the second connecting surface 354 and is closer to the first connecting surface 353 than the second connecting surface 354; in the height direction of the bracket 35, the bearing platform 356 and the first connecting surface 353 are distributed in a stepped manner. The bearing platform 356 of this embodiment extends along the length direction of the inner side surface 351 (the direction surrounding the cavity B). In other embodiments, the bearing platform 356 can be a plurality of independent steps, which are convexly arranged on the inner side surface 351 at intervals and arranged along the length direction of the inner side surface 351.

[0086] The outer side surface 352 of the bracket 35 is provided with a coupling portion 357, which is used to be fixedly connected to the main body 30. The coupling portion 357 can be a protrusion protruding from the outer side surface 352, or it can be a recessed portion recessed in the outer side surface 352. In this embodiment, the coupling portion 357 is an annular recessed portion recessed in the outer side surface 352, which is arranged around the cavity B, and can be understood as recessed portions being provided along the length direction of the outer side surface 352. Of course, the coupling portion 357 can also be two or more, which are spaced apart along the length direction of the outer side surface 352. In other embodiments, the coupling portion 357 is a plurality of protrusions or recessed portions, and the plurality of coupling portions 357 are spaced apart along the length direction of the outer side surface 352. In this embodiment, the bracket 35 is integrally formed by in-mold molding.

[0087] In one embodiment, in the height direction perpendicular to the bracket 35, the coupling portion 357 and the supporting platform 356 are at least partially staggered. As shown in Figure 5, the coupling portion 357 and the supporting platform 356 are completely staggered to avoid overlapping and reduce the thickness between the inner peripheral side surface 351 and the outer peripheral side surface 352 of the bracket 35, thereby ensuring the strength and high temperature resistance of the bracket 35.

[0088] In other embodiments, the bracket 35 is a rectangular frame without a joint or a support. When a transparent cover is subsequently provided, the transparent cover directly connects to the first connection surface 353 or the second connection surface 354. The bracket 35 is integrally formed in a mold or formed by die-cutting a plate.

[0089] As shown in Figure 6, which is a schematic cross-sectional view of the strip 100 shown in Figure 2, the connector 20 is located at one end of the circuit board 10. The circuit board 10 and the connector 20 are electrically connected by a binding process, or fixedly connected by welding. In the exemplary embodiment, the circuit board 10 and the connector 20 are fixedly connected and electrically connected by a binding process.

[0090] In the first implementation of the first embodiment of the present application, the bracket 35 is fixedly connected to the surface of the circuit board 10 by an adhesive layer 38. Specifically, after the circuit board 10 is fixedly connected to the connector 20, the second connection surface 354 of the bracket 35 faces the circuit board 10, and an adhesive layer 38 is connected between the second connection surface 354 of the bracket 35 and the surface of the circuit board 10. The bracket 35 and the circuit board 10 are fixedly connected by the adhesive layer 38. The adhesive layer 38 can be an adhesive glue or formed by dispensing. The circuit board 10 closes the mounting port of the cavity B of the bracket 35. The bracket 35 and the circuit board 10 are fixedly connected by adhesive, which increases the selectivity of assembly and facilitates the disassembly of the bracket 35 and the circuit board 10 to meet different production needs.

[0091] The bracket 35 and the circuit board 10 connected to the connector 20 are both embedded within the body 30 through an in-mold integral molding process. For specific molding methods, please refer to the detailed description of the manufacturing method herein. The circuit board 10 is located within the body 30, which can be understood as being completely embedded within the body 30. The bracket 35 is located on the side of the circuit board 10 facing away from the second surface 32. The coupling portion 357 of the bracket 35 cooperates with the protrusion 305 formed on the body 30, forming a curved coupling surface between the bracket 35 and the body 30 to enhance the bonding strength between the body 30 and the bracket 35. As shown in Figure 6, the body 30 wraps around the protrusion 357. The first connection surface 353 of the bracket 35 is exposed to the first surface 31, and the first connection surface 353 is flush with the first surface 31 (flush means that the distances between the two surfaces and the same horizontal plane are equal, and a certain tolerance is allowed); the opening 350 of the cavity B is located on the first surface 31, and the interior of the cavity B is exposed to the body 30 through the opening 350 (visible from the outside of the body 30, not protruding from the body 30), such as the surface of the circuit board and the support platform 356. It can be understood that the bracket 35 is partially embedded in the body 30. In the thickness direction of the bracket 35, the functional device 15 is located in the cavity B and is soldered to the surface of the circuit board 10 and electrically connected to the circuit board 10; of course, other functional devices can also be arranged on the circuit board 10 in the cavity B.

[0092] The transparent cover 36 is mounted on the support platform 356 within cavity B. The transparent cover 36 and support platform 356 are fixedly connected by an adhesive layer 37. The adhesive layer 37 is a rectangular frame structure with a contour substantially identical to that of the support platform 356. The adhesive layer 37 can be made of a transparent colloid. The adhesive layer 37 can firmly bond the transparent cover 36 and the bracket 35 and ensure a seal between the transparent cover 36 and the bracket 35, achieving waterproof and dustproof properties. The transparent cover 36 and the bracket 35 can also be separated by heating or other methods to facilitate maintenance of the components within cavity B. In one embodiment, the surface of the support platform 356 is rough. When the surface of the support platform 356 is rough, connecting the transparent cover 36 and the support platform 356 via the adhesive layer 37 can enhance the connection strength between the adhesive layer 37 and the support platform 356, thereby ensuring the connection between the transparent cover 36 and the body 30.

[0093] The transparent cover 36 allows light and photoelectric signals to be transmitted between the outside world and cavity B, facilitating the transmission and reception of signals by the functional device 15. For example, when the band 100 is worn on the wrist, the optical transmitter and receiver modules of the functional device 15 cooperate to capture the human pulse waveform and transmit the data to the main circuit board of the watch face 200 via the circuit board 10 and connector 20, thus enabling heart rate monitoring. In this embodiment, the outer surface of the transparent cover 36 is flush with the first surface 31, ensuring the smoothness of the outer surface of the band 100 and preventing abrasion to the wearer's skin.

[0094] In one embodiment, if the functional device 15 does not require close contact with human skin, such as a light sensor, a device that requires finger operation, or a motion monitoring device, the opening of the cavity B exposes the first surface 31, which is located on the outer surface of the belt body 100. The transparent cover 36 exposes the first surface 31. The transparent cover 36 can be partially decorated with an ink pattern or a film to ensure the required light transmission position of the functional device 15. In other words, the transparent cover 36 has a decorative area and a light-transmitting area. The decorative area (not shown) is opposite the functional device 15 and is used to transmit the light signal of the functional device 15. If an adhesive layer 37 is provided, the adhesive layer 37 can be selected to be light-transmitting or opaque according to the situation, and can also have a color.

[0095] In other embodiments, the transparent cover 36 can be higher than the surface of the body 30, specifically by 0.05mm-0.15mm. Whether located on the exterior or interior side of the strap 100, this can improve the conformity of the transparent cover 36 to the skin, allowing the functional device 15 to better transmit and receive signals to and from the human body. In other embodiments, the transparent cover 36 can be lower than the surface of the body 30. When the transparent cover 36 is located on the outside of the strap, it can be protected from scratches by external objects. For example, when placed on a table, the transparent cover 36 is recessed in the surface of the body 30 and does not come into contact with the table, preventing scratches and reducing wear time. It can be understood that when the transparent cover 36 is located on the exterior surface of the strap 100 and is either convex or recessed, it is more convenient for the user to observe and touch.

[0096] The connector 20 is fixedly connected to the connection end 33 of the body 30 and the surface of the connection end 33 is exposed. It can be understood that the connector 20 is combined with the body 30 by in-mold integral molding, that is, it is embedded in the body 30 and the connection end 33 is exposed. The connection end 33 is located on both sides of the connector 20 and is also provided with a buckle component for connecting to the dial 200. The buckle component can be a hinge, a buckle, a tongue, a magnet, a Velcro, etc., which is not limited in this application. Corresponding to the buckle component, the outer surface of the dial body 210 is also provided with a buckle structure for fixed connection with the buckle component of the belt body.

[0097] In one embodiment, as shown in Figure 4 , the bracket 35 is positioned closer to the connector 20 than the curved region 303, specifically closer to the rigid portion of the strap 100 and shortening the rigid portion. Alternatively, the circuit board 10 is a flexible circuit board extending along the length of the strap, and the bracket 35 is positioned further from the connector 20 than the curved region 303, such as where the buckle is located on the strap 100. This concentrates the rigid portion of the strap 100, thus preserving a longer flexible region within the strap 100.

[0098] In this embodiment, the bracket 35 is arranged closer to the connector 20 than the curved area 303; the connector 20 is arranged at the end of the belt body, and is plugged into the dial when the belt body 100 is connected to the dial 200, and the circuit board 10 and the bracket 35 mounted on the circuit board and the functional device 15 are not large in size and are arranged close to the connector 20, that is, close to the dial 200; at the same time, it is required to bring the functional device 15 and the connector close to achieve miniaturization to avoid occupying too much of the belt body. When the belt body 100 is worn on the wrist, the bracket 35 is located on the outside of the wrist (the wider side of the wrist, the same side as the dial), which will not affect the overall flexibility of the belt body, thereby improving the user's wearing experience.

[0099] In one embodiment, the circuit board 10 is a flexible circuit board and extends along the length of the belt body. When the belt body 100 is worn, it can be bent along with the belt body; in this way, the bracket 35 can be set not near the connector, but in the middle or tail of the belt body. When the belt body 100 is worn on the wrist, the bracket 35 is located on the inside of the wrist (on the same side as the palm), so it will not affect the wearing comfort.

[0100] Please refer to Figure 7, which is a flow chart of the method for manufacturing the strip shown in Figure 3. Please also refer to Figures 8 to 11. Figure 8 is a structural schematic diagram of the connector 20 being fixedly connected to the circuit board 10 in the method for manufacturing the strip of Figure 7; Figure 9 is a structural schematic diagram of the bracket 35 being connected to the circuit board 10 in the method for manufacturing the strip of Figure 7; and Figure 10 is a structural schematic diagram of the body 30 being formed in the method for manufacturing the strip of Figure 7.

[0101] Step S1: Fixing and electrically connecting the connector to the circuit board;

[0102] Step S2: arranging a bracket on the surface of the circuit board, wherein the bracket includes a cavity having an opening away from the surface of the circuit board;

[0103] Step S3: using in-mold injection molding to form a body embedded with the circuit board, the connector, and the bracket, wherein the opening of the cavity exposes the surface of the body;

[0104] Step S4: installing the functional device in the cavity and fixing it to the surface of the circuit board and conducting it;

[0105] Step S5: providing a transparent cover plate, and mounting the transparent cover plate on the bracket, wherein the transparent cover plate seals the opening of the cavity and is spaced apart from the circuit board.

[0106] 8 to 11 , the method for manufacturing the belt body of the embodiment shown in FIG. 7 specifically includes:

[0107] Step S1: Fix and electrically connect the connector 20 to the circuit board 10. As shown in FIG8 , the circuit board 10 and the connector 20 are fixed and electrically connected by a binding process. In other embodiments, the circuit board 10 and the connector 20 are fixed and electrically connected by welding.

[0108] Step S2: arranging a bracket on the surface of the circuit board.

[0109] In this embodiment, a bracket 35 having a cavity is provided. The bracket 35 is attached to the surface of the circuit board 10 via an adhesive layer 38. The opening of the cavity is located away from the circuit board 10. As shown in Figure 9, the bracket 35 is formed by injection molding. The bracket 35 and the circuit board 10 seal the other opening of the cavity B. The specific structure is as described in the above embodiment and will not be further elaborated here.

[0110] Step S3: Use an in-mold injection molding process to form a main body embedded with the circuit board, the connector and the bracket. As shown in Figure 10, specifically, the circuit board 10 connected to the connector, the connector 20 and the bracket 35 are implanted into the mold, and plastic is used for injection molding to form the main body 30. Liquid silicone can be selected for the main body 30. Among them, the main body 30 wraps the circuit board 10 connected to the connector, the connector 20 and the bracket 35, that is, the circuit board 10, the connector 20 and the bracket 35 are embedded in the main body 30. The circuit board 10 is located in the main body 30, which can be understood as being completely embedded in the main body 30. The connector 20 and the bracket 35 are partially embedded in the main body 30, and the connector 20 protrudes from one end of the main body 30. The bracket 35 is located on the side of the circuit board 10 facing away from the second surface 32. During injection molding, the molten material constituting the main body 30 flows into and fills the joint 357 of the bracket 35, forming a protrusion 305 connected to the joint 357. The protrusion 305 is plugged into the joint 357, and the joint surface between the main body 30 and the bracket 35 is a curved surface. The opening 350 exposes the first surface 31 of the main body 30 and is connected to the cavity B. The main body 30 of this embodiment can be a flexible material, such as liquid silicone, which can ensure the flexibility of the belt and ensure the comfort of the user when wearing it. The bracket 35 of this embodiment and the circuit board 10-level connector 20 form a module, and then the main body 30 is molded, which reduces the difficulty of the process. In other embodiments, the main body 30 can be formed by a hydraulic process using fluororubber or solid silicone.

[0111] Step S4: Install the functional device 15 in cavity B and securely connect it to the circuit board 10. The functional device 15 of this embodiment is a health monitoring device and is installed in cavity A through opening 350. It is soldered to the circuit board and electrically connected.

[0112] Step S5: A transparent cover plate 36 is provided and mounted on the bracket 35. The transparent cover plate 36 seals the opening 350 of the cavity B and is spaced apart from the circuit board 10. Specifically, as shown in Figure 6 , a glue layer 37 is first formed on the support platform 356 of the bracket 35. The glue layer 37 may be adhesive or formed by a dispensing process. The transparent cover plate 36 is then mounted on the support platform 356 and fixedly connected via the glue layer 37.

[0113] The embodiment of the present application modularizes electronic components, such as the electrical connector 20, the circuit board 10, and the bracket 35, and performs in-mold injection molding on them together to form the main body 30. The main body 30 is embedded and connected with the electrical connector 20, the circuit board 10, and the bracket 35 (the main body covers the electrical connector 20, the circuit board 10, and the bracket) to form the belt body 100. This avoids the need for additional assembly parts, simplifies the structure, and improves processing accuracy. In addition, the belt body and the electronic components are modularly processed, which not only optimizes the processing technology, but also provides a high degree of integration between the electrical connector 20, the circuit board 10, and the bracket 35 and the main body 30, strong reliability, and achieves a waterproof and dustproof effect. The bracket 35 has sufficient supporting strength for the transparent cover 36. The functional device is arranged in the cavity B formed by the bracket 35, which prevents the belt body 100 from being hit or squeezed against the functional device 15 during use, thereby avoiding damage to the functional device 15.

[0114] Please refer to Figure 11, which is a schematic cross-sectional view of one embodiment of the belt shown in Figure 3. In the second embodiment of the first embodiment of the present application, unlike the first embodiment, the bracket 35 is formed on the surface of the circuit board 10 by in-mold injection molding. The second connecting surface 354 in Figure 4 is the portion of the bracket 35 that contacts the circuit board when it is formed on the circuit board 10.

[0115] The manufacturing method of this embodiment differs from the manufacturing method of the above-mentioned embodiment in step S2; the other steps are the same and will not be further explained. Figure 12 is a schematic diagram of the structure of connecting the bracket 35 to the circuit board 10 in the manufacturing method of the strip of Figure 11; Figure 13 is a schematic diagram of the structure of forming the body 30 in the manufacturing method of the strip of Figure 11; Figure 14 is a schematic diagram of the structure of installing the functional device 15 in the cavity in the manufacturing method of the strip of Figure 11.

[0116] The method for manufacturing the belt 100 of this embodiment is as follows:

[0117] Step S10: The connector 20 is fixedly connected to the circuit board 10 and electrically connected.

[0118] Step S20: The circuit board 10, with the connector connected, is placed into an injection mold. Through a first injection molding process, a bracket 35, as shown in Figure 4, is formed on the surface of the circuit board 10. The bracket 35 forms a cavity B with an opening 350 facing away from the circuit board 10. The outer side surface 352 of the bracket 35 forms a bonding portion 357 (its structure is the same as that of the first embodiment), and a support platform 356 is formed within the cavity B. The bonding surface between the bracket 35 and the circuit board 10 is the second connection surface 354 of the first embodiment. It should be noted that the surface portion of the circuit board 10 intended for connection to the bracket 35 does not have wiring or components, and a connection area can be reserved in advance based on the bracket to ensure connection accuracy. The bracket 35 is made of a relatively hard plastic material, such as polyamide (PA). In the belt manufacturing method of this embodiment, the bracket 35 is directly connected to the circuit board 10 through in-mold injection molding, eliminating the bonding layer, reducing the overall thickness, and conserving space in the thickness direction of the belt.

[0119] It is understood that the bracket 35 shown in Figure 4 is directly connected to the circuit board after in-mold molding. The exploded view of Figure 4 is for the purpose of clearly showing the structure of the bracket.

[0120] Step S30: secondary injection molding is performed in the mold to form the body 30, and the circuit board 10, the connector 20 and the bracket 35 are embedded in the body 30. Specifically, after the bracket is first injection molded, the body 30 is formed by the second injection molding in the mold.

[0121] Step S40: Install the functional device 15 in the cavity B and securely connect it to the circuit board 10 and conduct it.

[0122] Step S50 : Mount the transparent cover 36 on the bracket 35 and close the opening 350 , as shown in FIG11 .

[0123] Please refer to Figure 15, which is a cross-sectional schematic diagram of the second embodiment of the belt body shown in Figure 2. In the second embodiment of the present application, unlike the first embodiment, the protective shell 30A includes a bracket 35a and a transparent cover plate 36a. The bracket 35a and the transparent cover plate 36a are integrally formed, and the bracket 35a includes a connecting surface 351a and an opening 352a. The connecting surface 351a surrounds the opening 352a and faces away from the transparent cover plate 36a. The bracket 35a of this embodiment is not provided with a supporting platform and a joint portion, which further enhances the strength of the bracket 35a. In addition, the integral formation with the transparent cover plate 36a reduces the overall thickness of the protective shell 30A, reduces the joint surface, enhances the sealing performance, and improves the processing accuracy.

[0124] Specifically, the protective case 30A is a rectangular housing. The bracket 35a is formed on the periphery of one surface of the transparent cover 36a and, together with the transparent cover 36a, forms a cavity C. The opening 352a can be understood as the opening of the cavity C. The connection surface 351a of the bracket 35a surrounds the opening 352a, and the transparent cover 36a is spaced apart and opposed to the opening 352a. The protective case 30A is connected to the circuit board 10, with the connection surface 351a connected to the surface of the circuit board 10. The opening 352a faces the circuit board 10 and is enclosed by the circuit board 10. This can be understood as the cavity B being enclosed by the circuit board 10.

[0125] In this embodiment, the method for making the belt body is different from that in the first embodiment in that the bracket 35a and the transparent cover 36a are injection molded from two materials. The bracket 35a and the transparent cover 36a are integrally molded, which improves processing efficiency and reduces the thickness of the protective shell.

[0126] Please refer to Figures 16 and 17. Figure 16 is a flowchart of a method for manufacturing the second embodiment of the belt shown in Figure 15. Figure 17 is a cross-sectional view of the protective shell 30A of Figure 15 being mounted on the circuit board 10. The belt manufacturing method of this embodiment includes:

[0127] Step S100: The connector 20 is fixedly connected to the circuit board 10 and electrically connected. Functional components are connected to the circuit board 10.

[0128] Step S200: Injection molding forms a protective shell 30A, which includes a bracket 35a and a transparent cover plate 36a. The bracket 35a and the transparent cover plate 36a enclose a cavity C with an opening 352a. Specifically, the bracket 35a and the transparent cover plate 36a are both made of a plastic material with relatively high hardness. The specific materials of the bracket 35a and the transparent cover plate 36a are different. The transparent cover plate 36a is made of a material with high light transmittance, such as a highly transparent organic polymer material, silicone. The material of the bracket 35a can be transparent or opaque and has a certain hardness. The bracket 35a and the transparent cover plate 36a of this embodiment are integrally formed, which can reduce the combined cross-section of the bracket 35a and the transparent cover plate 36a, improve the waterproof effect, and reduce the bonding / bonding interface, which can also bring space benefits.

[0129] Step S300: Connect the protective shell 30A to the surface of the circuit board 10, encapsulate the functional device 15 in the cavity C, and the transparent cover is spaced apart from the circuit board; specifically, the opening 350 faces the circuit board 10, and the connecting surface 351a and the surface of the circuit board 10 are connected by an adhesive layer (not shown in the figure), and the circuit board 10 encapsulates the cavity C.

[0130] Step S400: The circuit board 10 connected with the connector, the connector 20 and the protective shell 30A are placed in a mold for injection molding to form the body 30. The circuit board 10, the connector 20 and the protective shell 30A are embedded in the body 30, and the transparent cover 36a exposes the first surface 31 of the body 30.

[0131] As shown in Figure 18, Figure 18 is a cross-sectional schematic diagram of the third embodiment of the belt body shown in Figure 2; the structure of the protective shell A is exactly the same as the protective shell structure of the second embodiment. The difference from the manufacturing method of the second embodiment is that the bracket and the transparent cover plate are made of the same material, and the bracket 35a and the transparent cover plate 36a are both made of materials with high transmittance and high hardness, such as highly transparent organic polymer materials such as organic silicone. The bracket 35a and the transparent cover plate 36a of this embodiment are integrally molded using the same material, which can simplify the molding process and reduce processing costs. The specific method of the manufacturing method in the third embodiment of the present application refers to the second embodiment. The difference is that in step S200, the bracket 35a and the transparent cover plate 36a are both injection molded using materials with high transmittance and high hardness. The other steps are the same and will not be repeated here.

[0132] Referring to Figure 4 , the fourth embodiment of the present application differs from the first embodiment in that the body 30 is provided with a mounting slot 301 and a retaining slot is provided at the connecting end. The circuit board 10 and the body 30 are molded by in-film injection molding. The body 30 is flexible and has a certain degree of elasticity. The connector 20 is inserted into the retaining slot through the notch of the retaining slot, with an interference fit therebetween. The bracket 35 is inserted into the mounting slot 301 through the notch of the mounting slot 301. During this process, the bracket 35 squeezes the body 30 around the mounting slot 301, causing deformation until the bracket 35 is fully inserted into the mounting slot 301. The body 30 then returns to its natural state, retaining the bracket within the body 30 and preventing it from interfering with the circuit board. The body 30, bracket 35, and connector 20 of the belt of this embodiment are replaceable, facilitating maintenance of the belt 100.

[0133] The above are only some of the embodiments and implementations of this application. The scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
