[0007] 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 plate and be transmitted out of the body;

[0008] The wearable device of the present application is a smart watch, which contains functional devices in the body, freeing up the space of the dial and saving the dial space; it can also be understood as the functional devices in the body adding some functions to the original smart functions of the watch, such as expanding the scope of use of the smart watch. Moreover, the bracket of the present application is embedded in the body, which improves the sealing performance of the joint surface and simplifies the processing technology. The functional device is encapsulated in the cavity of the bracket, which has a supporting and enclosing effect on the device, isolates the body and the functional device, and can also prevent the functional device from being damaged by external forces. In addition, the bracket can support the transparent cover to ensure that the optical path performance is provided for the functional device.

[0009] In one embodiment, the body, the circuit board and the bracket are an integrally formed part. The integrally formed part of this embodiment means that the circuit board and the bracket are placed in a mold, and the body is formed by injection molding in the mold, wherein the body will wrap the circuit board and the bracket. In this way, the waterproof performance of the connection interface between the body, the circuit board and the bracket is ensured.

[0010] 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 an integrally formed part. The bracket is connected to the circuit board by an adhesive layer, which facilitates the disassembly and position adjustment of the bracket. The bracket and the circuit board are an integrally formed part, 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, injecting the bracket into the mold, and connecting one side of the bracket to the surface of the circuit board.

[0011] In one embodiment, the bracket surrounds the cavity, the cavity has an opening arranged away from the circuit board, the opening exposes the surface of the body, and the transparent cover seals the opening. The transparent cover and the bracket in this embodiment are separate, which is convenient for disassembling the functional components in the cavity and facilitating maintenance.

[0012] 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 and connected to the bearing platform via an adhesive layer. The connection via the adhesive layer can achieve better sealing performance.

[0013] In one embodiment, the transparent cover plate and the bracket are integrally formed by injection molding, and at least the material of the transparent cover plate is a light-transmitting material. In this embodiment, the transparent cover plate and the bracket are integrally formed by injection molding without the need for a glue layer, which reduces the thickness of the protective shell, reduces the bonding interface, improves the sealing performance, and simplifies the installation process.

[0014] In one embodiment, the transparent cover and the bracket form the cavity, the bracket includes a connection surface, the connection surface surrounds the opening of the cavity, the protective shell is mounted on the surface of the circuit board, the functional device is located in the cavity, the connection surface and the surface of the circuit board are connected and fixed by an adhesive layer, and 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 loaded into the cavity through the opening.

[0015] In one embodiment, the transparent cover plate protrudes from the surface of the body. Regardless of whether the transparent cover plate is located on the outer surface or the inner side of the belt body, the fit between the transparent cover plate and the skin can be improved, so that the functional device and the human body can better send and receive signals. When the transparent cover plate is located on the outer surface of the belt body and protrudes, the protruding transparent cover plate is more convenient for users to observe and touch.

[0016] When the transparent cover is located on the outer surface of the belt body, a decorative area can be partially formed on the transparent cover, including patterns and colors, etc., to enhance the recognition of the position of the functional components and beautify the appearance of the belt body.

[0017] In one embodiment, the joint surface between the bracket and the body is curved. Injection molding the joint surface between the bracket and the body enhances the connection strength between the two.

[0018] In one embodiment, the belt body further includes a connector, the connector and the body are integrally formed, the connector is conductively connected to the circuit board, and one end of the connector is exposed from the body. The connector is used to plug into the dial, and transmits the signal of the functional device on the circuit board to the main board of the dial. Using the connector to directly plug into the dial can ensure physical and electrical connection, which is convenient for assembly and maintenance.

[0020] 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 or affect the wearing comfort.

[0021] The circuit board is a flexible circuit board, and the bracket is farther away from the connector than the bending area, so that the bracket may not be set near the connector, but may be set in the middle or tail of the belt body. When the belt body 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.

[0022] The present application provides a wearable device, which includes a dial and the above-mentioned belt body, wherein a connector is embedded at one end of the belt body, and the connector is arranged adjacent to the bracket and electrically connected to the circuit board;

For example, the button can respond to the user's finger pressing operation to display the main interface. In summary, the smart watch of this application has the functions of a common smart watch, which are not listed one by one again.

[0070] The strap 100 includes two straps 100, which are respectively connected to opposite sides of the dial 200, and the ends of the two straps 100 away from the dial 200 can be buckled with each other to fix the smart watch on the wearer's wrist. The appearance of the two straps 100 can be the same or different, and the structure can be the same or different. These are not limited here. Among them, at least one of the straps 100 is provided with a functional device of a smart phone, and when both straps 100 have functional devices, their functions are different.

[0071] See also Figure 2 , Figure 3 and Figure 4 , Figure 2 for Figure 1The schematic diagram of the structure of the belt body of the wearable device shown in FIG. Figure 3 for Figure 2 The schematic diagram of the exploded structure of the transparent cover and the main body 30 of the first embodiment of the belt 100 is shown; Figure 4 for Figure 1 The schematic diagram of the exploded structure of the belt body of the first embodiment of the belt body 100 is shown. For the convenience of description, the width direction of the belt body 100 is defined as the X-axis direction, the length direction of the belt body 100 is defined as the Y-axis direction, and the thickness direction of the belt body 100 is defined as the Z-axis direction. The X-axis direction, the Y-axis direction and the Z-axis direction are mutually perpendicular. It should be noted that Figure 4 The components of the belt body 100 are shown in an exploded manner to assist the following description and provide a clearer understanding of the structure of the belt body 100. In some embodiments, Figure 4 The exploded display of the components of the belt body 100 has no necessary relationship with the assembly sequence and connection method of the components.

[0072] This embodiment is described by taking the belt body 100 for storing functional devices as an example. The belt body 100 is provided with a circuit board 10, a functional device 15 and a connector 20; the functional device 15 and the connector 20 are electrically connected to the circuit board 10, and the connector 20 is used to be plugged and electrically connected to 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 arranged inside the dial body 210. The main circuit board is provided with a connecting device or a gold finger for plugging with the connector 20 to realize the electrical connection between the circuit board 10 and the functional device 15 and the main circuit board.

[0073] 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 a human pulse waveform when it is close to the wearer's wrist.

[0074] In other embodiments, the strap 100 of the present application may also be provided with other functional devices, such as a navigation module, an audio device, etc., without being limited in number and position, as long as it does not affect the original wearing and fixing function and comfort of the strap. The smart watch of the present application integrates some functional devices into the strap, improves the diversification of the smart functions of the smart watch, makes full use of the space of the strap (strap), and can make room for the dial, which can improve the flexibility of the dial design.

[0075] The belt body 100 further includes a body 30 and a protective shell 30A, the circuit board 10 and the protective shell 30A are embedded in the body 30, the functional device 15 is accommodated in the protective shell 30A and fixedly connected to the circuit board 10, and 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 accommodated in the body 30, or is covered by the body 30.

[0076] The body 30 is in the shape of a long strip, and includes a first surface 31, a second surface 32, and a connecting end 33. The first surface 31 and the second surface 32 are arranged opposite to each other along the thickness direction of the belt body 100. In one embodiment, the first surface 31 is the inner side of the belt body 100, and faces the human body when worn. The second surface 32 is the appearance surface, and a pattern that increases the beauty can be provided. In another embodiment, the first surface 31 is the appearance surface of the belt body 100, and the second surface 32 is the inner side of the belt body 100. The appearance surface of the belt body 100 is determined according to the operation mode of the functional device 15.

[0077] In this embodiment, the body 30 can be made of a flexible material, specifically, by in-mold integral molding; the flexible material is such as liquid silicone, fluororubber, etc. The body 30 shown includes a bending area 303, and the bending area 303 is located between the opposite ends of the length direction of the body 30. When the belt 100 is worn, the bending area 303 bends from the outside of the wrist to the inside of the wrist to adapt to the contour of the wrist. It should be noted that the bending area 303 is only for the convenience of understanding the structure of the belt 100, and does not necessarily represent the position and angle dimensions shown in the figure. Moreover, the appearance surface of the belt 100 is not limited to the concave and convex surface shown in the figure, and can also be a plane or other curved surface.

[0078] The body 30 further includes a mounting groove 301 and a plugging groove 302. The mounting groove 301 is recessed from the first surface 31 to the second surface 32. The plugging groove 302 is recessed at the connection end 33 and communicates with the mounting groove 301. In fact, the mounting groove 301 and the plugging groove 302 are directly formed when the body 30 is injection molded. The mounting groove 301 accommodates the bracket 35 and the circuit board 10. The groove wall of the accommodating groove is tightly connected with the bracket 35 and the circuit board 10. The shape of the plugging groove 302 is adapted to the connector 20.

[0079] like Figure 3 As shown, in the first embodiment of the present application, the protective shell 30A includes a bracket 35 and a transparent cover plate 36, and the bracket 35 and the transparent cover plate 36 are fixedly connected by an adhesive layer. For the convenience of description, the height direction of the bracket 35 is defined as the thickness direction of the belt body 100.

[0080] 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 accommodated in the cavity B and fixedly connected to the circuit board 10, and the 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, covers and encapsulates the cavity B. In this embodiment, the bracket 35 is made of a plastic material with relatively high hardness, such as polyamide (PA). It can be understood that the selection of the material of the bracket 35 can also maintain its own shape under the molding temperature and pressure of the body 30, ensure mechanical properties, and thus reliably protect the functional device 15.

[0081] In one embodiment, the hardness of the bracket 35 is greater than the hardness of the body 30, which can be understood as the melting point (softening point) of the material of the bracket 35 is greater than the melting point (softening point) of the material of the body 30, so as to avoid the bracket 35 from being completely melted during the high-temperature injection molding of the body 30. The transparent cover 36 is made of plastic or glass with high light transmittance, and its outer surface has strong wear resistance. The transparent cover 36 is connected to the bracket 35 and the body 30 through an adhesive layer 37.

[0082] For details, please refer to Figure 5 , Figure 5 for Figure 4 The cross-sectional schematic diagram of the bracket shown in the figure; the bracket 35 is a rectangular frame structure and encloses a cavity B with an opening. Among them, the cavity B is provided with two opposite openings 350, one opening 350 is called the opening of the cavity, and the other opening can be called the installation port. The height direction of the bracket 35 is the height direction of the cavity, which is also the thickness direction of the belt body 100, and the two openings 350 are arranged opposite to 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 back to back, and the inner peripheral side surface 351 is the surface of the cavity wall of the cavity B. Along the height direction of the bracket 35, the first connecting surface 353 and the second connecting surface 354 are arranged back to back, and the first connecting surface 353 and the second connecting surface 354 both connect the inner peripheral side surface 351 and the outer peripheral side surface 352. The first connecting surface 353 surrounds the opening of the cavity B, and the second connecting surface 354 surrounds the installation port of the cavity B.

[0083] 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.

[0084] The outer peripheral side surface 352 of the bracket 35 is provided with a coupling portion 357, and the coupling portion 357 is used to be fixedly connected to the body 30. The coupling portion 357 can be a protrusion protruding from the outer peripheral side surface 352, or it can be a recessed portion recessed in the outer peripheral side surface 352. In the present embodiment, the coupling portion 357 is an annular recessed portion recessed in the outer peripheral side surface 352, which is arranged around the cavity B, and can be understood as recessed portions are provided along the length direction of the outer peripheral side surface 352. Of course, the coupling portion 357 can also be two or more, which are arranged at intervals along the length direction of the outer peripheral side surface 352. In other embodiments, the coupling portion 357 is a plurality of protrusions or recesses, and the plurality of coupling portions 357 are arranged at intervals along the length direction of the outer peripheral side surface 352. In the present embodiment, the bracket 35 is integrally formed by in-mold molding.

[0085] In one embodiment, in a height direction perpendicular to the bracket 35, the coupling portion 357 and the support platform 356 are at least partially offset. Figure 5 As shown, the coupling portion 357 and the support 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 .

[0086] In other embodiments, the bracket 35 is a rectangular frame without a joint and a support platform. 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 the bracket 35 is formed by die cutting of a plate.

[0087] like Figure 6 As shown, Figure 6 for Figure 2 The schematic cross-sectional view of the belt 100 is shown; the connector 20 is located at one end of the circuit board 10, and the circuit board 10 and the connector 20 are electrically connected by a binding process, or fixedly connected by welding, and electrically connected. The schematic circuit board 10 and the connector 20 are fixedly connected and electrically connected by a binding process.

[0088] 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, and the adhesive layer 38 can be an adhesive or formed by dispensing. The circuit board 10 closes the installation port of the cavity B of the bracket 35. The bracket 35 is fixedly connected to the circuit board 10 by bonding, which increases the selectivity of assembly and facilitates the disassembly of the bracket 35 and the circuit board 10 to meet different production needs.

[0089] The bracket 35 and the circuit board 10 connected with the connector 20 are both embedded in the body 30 through an in-mold integrated molding process. For the specific molding method, please refer to the specific description of the manufacturing method in this article; wherein, the circuit board 10 is located in the body 30, which can be understood as being completely embedded in the body 30. The bracket 35 is located on the side of the circuit board 10 facing away from the second surface 32. The joint portion 357 of the bracket 35 cooperates with the protrusion 305 formed on the body 30, and a curved joint surface is formed between the bracket 35 and the body 30 to enhance the bonding force between the body 30 and the bracket 35; Figure 6 As shown, the body 30 wraps the convex joint 357. The first connection surface 353 of the bracket 35 exposes the first surface 31, and the first connection surface 353 is flush with the first surface 31 (flush means that the distances of the two surfaces to 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 then the inside of the cavity B is exposed to the body 30 through the opening 350 (it can be seen from the outside of the body 30, which does not mean that it protrudes 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 welded to the surface of the circuit board 10 and is electrically conductive with the circuit board 10; of course, other functional devices can also be arranged on the circuit board 10 in the cavity B.

[0090] The transparent cover plate 36 is mounted on the support platform 356 in the cavity B, and the transparent cover plate 36 and the support platform 356 are fixedly connected by the adhesive layer 37. The adhesive layer 37 is a rectangular frame structure, and its outline is roughly the same as the outline 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 plate 36 and the bracket 35 and can ensure the sealing performance between the transparent cover plate 36 and the bracket 35, so as to achieve waterproof and dustproof; the transparent cover plate 36 and the bracket 35 can also be separated by heating and other methods, so as to facilitate the maintenance of the devices in the cavity B. In one embodiment, the surface of the support platform 356 is a rough surface. When the surface of the support platform 356 is a rough surface, the transparent cover plate 36 and the support platform 356 are connected by the adhesive layer 37, so that the connection strength between the adhesive layer 37 and the support platform 356 can be enhanced, and the connection performance between the transparent cover plate 36 and the body 30 can be ensured.

[0091] The transparent cover plate 36 can transmit light and photoelectric signals between the outside world and the cavity B, which is beneficial to the signal transmission and reception of the functional device 15. For example, when the belt body 100 is worn on the wrist, the optical transmission module and the receiving module of the functional device 15 cooperate to obtain the human pulse waveform, and transmit the specific data to the main circuit board of the dial 200 through the circuit board 10 and the connector 20 to realize heart rate monitoring. In this embodiment, the outer surface of the transparent cover plate 36 is flush with the first surface 31, ensuring the flatness of the outer surface of the belt body 100 and avoiding abrasion of the wearer's skin when worn.

[0092] In one embodiment, if the functional device 15 is a device that does not need to be close to human skin, such as a light sensor, or a device that needs finger operation, or a motion monitoring device; the opening of the cavity B exposes the first surface 31, that is, it is located on the outer surface of the belt body 100, and the transparent cover 36 exposes the first surface 31. The transparent cover 36 can be partially decorated with ink patterns or partially attached with film sheets as decoration to ensure the required light-transmitting position of the functional device 15. That is to say, the transparent cover 36 has a decorative area and a light-transmitting area. The decorative area (not shown) is opposite to the functional device 15 and is used for the passage of the optical signal of the functional device 15. If a glue layer 37 is provided, the glue layer 37 can also be selected to be light-transmitting or opaque according to the situation, and can also have a set color.

[0093] In other embodiments, the transparent cover plate 36 may be higher than the surface of the body 30, specifically 0.05mm-0.15mm higher. Whether it is located on the exterior surface or the inner side of the belt body 100, the fit of the transparent cover plate 36 to the skin can be improved, so that the functional device 15 can better send and receive signals with the human body. In other embodiments, the transparent cover plate 36 may be lower than the surface of the body 30, and when the transparent cover plate 36 is located on the outside of the belt body, it can be avoided from being scratched by foreign objects. For example, when it is placed on a desktop, the transparent cover plate 36 is recessed in the surface of the body 30 and will not contact the desktop, avoiding being scratched and reducing wear time. It can be understood that when the transparent cover plate 36 is located on the exterior surface of the belt body 100 and is convex or recessed, the transparent cover plate 36 is more conducive to observation and touch by the user.

[0094] 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 buckle parts for connecting with the dial 200. The buckle parts can be hinges, buckles, tongues, magnets, Velcro, etc., which are not limited in this application. Corresponding to the buckle parts, a buckle structure for fixed connection with the buckle parts of the belt body is also provided on the outer surface of the dial body 210.

[0095] In one embodiment, Figure 4 As shown, the bracket 35 is arranged closer to the connector 20 than the bending area 303, that is, closer to the harder part of the belt body 100 and shortens the harder part. Alternatively, the circuit board 10 is a flexible circuit board, and the circuit board 10 extends along the length direction of the belt body, and the bracket 35 is arranged farther from the connector 20 than the bending area 303, such as the position where the buckle is arranged on the belt body 100. That is, the harder parts in the belt body 100 are concentrated, so that a longer flexible area can be reserved for the belt body 100.

[0096] In this embodiment, the bracket 35 is arranged closer to the connector 20 than the bending 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 very large 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.

[0097] In one embodiment, the circuit board 10 is a flexible circuit board and extends along the length direction 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 may not be set near the connector, but may be set 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.

[0098] See also Figure 7 , Figure 7 for Figure 3 Please also refer to the flowchart of the method for making the belt body shown in Figure 8-Figure 11 , Figure 8 for Figure 7 A schematic diagram of a structure in which a connector 20 is fixedly connected to a circuit board 10 in a method for manufacturing a belt body; Fig. 9 for Figure 7 A structural diagram of connecting the bracket 35 to the circuit board 10 in the method for manufacturing the belt body; Fig.10 for Figure 7 A schematic diagram of the structure of the main body 30 formed in the method for manufacturing the belt body.

[0099] Step S1: fix and electrically connect the connector to the circuit board;

[0100] Step S2: arranging a bracket on the surface of the circuit board, wherein the bracket comprises a cavity having an opening away from the surface of the circuit board;

[0101] 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;

[0102] Step S4: installing the functional device in the cavity and fixing and connecting it to the surface of the circuit board;

[0103] Step S5: providing a transparent cover plate, and installing 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.

[0104] Combination Figure 8-Figure 11 , Figure 7 The method for making the belt body of the present embodiment shown specifically includes:

[0105] Step S1: The connector 20 is fixedly connected to the circuit board 10 and electrically connected. Figure 8 As shown, 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.

[0106] Step S2: Arranging a bracket on the surface of the circuit board.

[0107] In this embodiment, a bracket 35 having a cavity is provided, and the bracket 35 is connected to the surface of the circuit board 10 through an adhesive layer 38, and the opening of the cavity is located at a position where the bracket 35 is away from the circuit board 10. Fig. 9 Specifically, the bracket 35 is formed by an injection molding process, and the bracket 35 and the circuit board 10 close the other opening of the cavity B. The specific structure is as described in the above embodiment, and will not be described in detail here.

[0108] Step S3: Using an in-mold injection molding process to form a body embedded with the circuit board, the connector and the bracket. Fig.10 Specifically, the circuit board 10, the connector 20 and the bracket 35 connected with the connector are implanted into the mold, and plastic is used for injection molding to form the body 30. The body 30 can be made of liquid silicone. Among them, the body 30 wraps the circuit board 10, the connector 20 and the bracket 35 connected with the connector, that is, the circuit board 10, the connector 20 and the bracket 35 are embedded in the body 30. The circuit board 10 is located in the body 30, which can be understood as being completely embedded in the body 30. The connector 20 and the bracket 35 are partially embedded in the body 30, and the connector 20 protrudes from one end of the 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 body 30 flows into and fills the joint 357 of the bracket 35, forming a protrusion 305 connected to the joint 357, and the protrusion 305 is plugged into the joint 357. The joint surface between the body 30 and the bracket 35 is a curved surface. The opening 350 exposes the first surface 31 of the body 30 and communicates with the cavity B. The body 30 of this embodiment can be made of a flexible material, such as liquid silicone, which can ensure the flexibility of the belt and the comfort of the user. The bracket 35 of this embodiment and the circuit board 10-level connector 20 form a module, and then the body 30 is formed, which reduces the process difficulty. In other embodiments, the body 30 can be made of fluororubber or solid silicone and formed by an oil pressure process.

[0109] Step S4: Install the functional device 15 in the cavity B and connect it to the circuit board 10. The functional device 15 of this embodiment is a monitoring device for monitoring health, which is installed in the cavity A through the opening 350 and is welded to the circuit board by welding or other processes.

[0110] Step S5: Provide a transparent cover plate 36, and install the transparent cover plate 36 on the bracket 35, wherein the transparent cover plate 36 seals the opening 350 of the cavity B and is spaced apart from the circuit board 10. Figure 6 As shown, specifically, firstly, a glue layer 37 is formed on the support platform 356 of the bracket 35 , and the glue layer 37 can be a back glue or formed by a dispensing process. Then, the transparent cover plate 36 is mounted on the support platform 356 and fixedly connected by the glue layer 37 .

[0111] The embodiment of the present application modularizes electronic devices, such as the electrical connector 20, the circuit board 10 and the bracket 35, and performs in-mold injection molding together to form a main body 30 through in-mold molding. 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 a belt body 100, avoiding the need for additional assembly parts, simplifying the structure, and improving the processing accuracy. The belt body and the electronic devices are modularly processed, which not only optimizes the processing technology, but also has a high degree of integration between the electrical connector 20, the circuit board 10 and the bracket 35 and the main body 30, and has strong reliability, thereby achieving a waterproof and dustproof effect. The bracket 35 has sufficient supporting strength for the transparent cover 36, and the functional device is arranged in the cavity B formed by the bracket 35, so as to avoid the belt body 100 from being hit or squeezed to the functional device 15 during use, thereby avoiding damage to the functional device 15.

[0112] See also Fig.11 , Fig.11 for Figure 3 A cross-sectional schematic diagram of an embodiment of the belt body shown; in the second embodiment of the first embodiment of the present application, different from the above-mentioned first embodiment, the bracket 35 is formed on the surface of the circuit board 10 by in-mold injection molding. Figure 4 The second connection surface 354 is the portion that contacts the circuit board when the bracket 35 is formed on the circuit board 10 .

[0113] The manufacturing method of this embodiment differs from the manufacturing method of the above-mentioned embodiment in step S2, and the other steps are the same and will not be explained in detail again. Fig.12 for Fig.11 A structural diagram of connecting the bracket 35 to the circuit board 10 in the method for manufacturing the belt body; Fig.13 for Fig.11 A schematic diagram of the structure of the main body 30 formed in the method for manufacturing the belt body; Fig.14 for Fig.11 A schematic structural diagram of installing a functional device 15 in a cavity in a method for manufacturing a belt body.

[0114] The method for manufacturing the belt body 100 of this embodiment is specifically as follows:

[0115] Step S10: The connector 20 is fixedly connected to the circuit board 10 and electrically connected.

[0116] Step S20: Place the circuit board 10 connected with the connector into the injection mold, and form a molded portion on the surface of the circuit board 10 through the first injection molding. Figure 4The bracket 35 shown. The bracket 35 encloses a cavity B having an opening 350 away from the circuit board 10, and the outer peripheral side surface 352 of the bracket 35 forms a bonding portion 357 (whose structure is the same as that of the first embodiment), and a bearing platform 356 is formed in 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 used for connecting with the bracket 35 is not provided with wiring and devices, and the connection area can be reserved in advance according to the bracket to ensure the connection accuracy. The bracket 35 is made of a plastic material with relatively high hardness, such as polyamide (PA) material. In the method for making the belt body of this embodiment, the bracket 35 is directly connected to the circuit board 10 by in-mold injection molding, which reduces the bonding layer, can reduce the overall thickness, and can save space in the thickness direction of the belt body.

[0117] Understandably, Figure 4 The bracket 35 shown is directly connected to the circuit board after in-molding. Figure 4 The exploded view is to clearly see the structure of the bracket.

[0118] 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 firstly injection molded, the body 30 is formed by the second injection molding in the mold.

[0119] Step S40 , installing the functional device 15 in the cavity B and fixing and connecting the functional device 15 to the circuit board 10 .

[0120] Step S50: Install the transparent cover 36 on the bracket 35 and close the opening 350. Fig.11 shown.

[0121] See also Fig.15 , Fig.15 for Figure 2 A cross-sectional schematic diagram of the second embodiment of the belt body shown. 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, and 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 bearing platform and a joint portion, which further improves the strength of the bracket 35a, and the integral molding 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.

[0122] Specifically, the protective shell 30A is a rectangular cover, the bracket 35a is formed on the periphery of one surface of the transparent cover plate 36a, and forms a cavity C with the transparent cover plate 36a, which can be understood as the opening 352a is the opening of the cavity C. The connecting surface 351a of the bracket 35a surrounds the opening 352a, the transparent cover plate 36a is spaced and opposite to the opening 352a, the protective shell 30A is connected to the circuit board 10, the connecting surface 351a is connected to the surface of the circuit board 10, and the opening 352a faces the circuit board 10 and is closed by the circuit board 10. It can be understood that the cavity B is closed by the circuit board 10.

[0123] 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 plate 36a are injection molded by two materials. The bracket 35a and the transparent cover plate 36a are integrally molded, which improves processing efficiency and reduces the thickness of the protective shell.

[0124] See also Fig.16 and Fig.17 , Fig.16 for Fig.15 The manufacturing flow chart of the manufacturing method of the second embodiment of the belt body shown in FIG. Fig.17 for Fig.15 The protective shell 30A is installed on the circuit board 10. The belt manufacturing method of this embodiment includes:

[0125] Step S100: The connector 20 is fixedly connected to the circuit board 10 and electrically connected. The circuit board 10 is connected with functional devices.

[0126] Step S200: Injection molding to form a protective shell 30A, the protective shell 30A 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, and 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 such as 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 / combination interface, which can also bring space benefits.

[0127] 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), and the circuit board 10 encapsulates the cavity C.

[0128] Step S400: implant the circuit board 10 connected with the connector, the connector 20 and the protective shell 30A into a mold for injection molding to form a body 30, wherein 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.

[0129] like Fig.18 As shown, Fig.18 for Figure 2 The schematic cross-sectional view of the third embodiment of the belt body shown in the figure; the structure of the protective shell A is exactly the same as the protective shell structure of the second embodiment. Different from the manufacturing method of the second embodiment, 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 silicone. The bracket 35a and the transparent cover plate 36a of this embodiment are integrally formed 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, and the other steps are the same and will not be repeated here.

[0130] Please combine Figure 4 In the fourth embodiment of the present application, different from the first embodiment, the body 30 is provided with a mounting groove 301, and the connection end is provided with a limiting groove; the circuit board 10 and the body 30 are molded by film injection, the body 30 is flexible and has a certain elasticity, the connector 20 is inserted into the limiting groove through the notch of the limiting groove and the limiting groove is interference fit, and the bracket 35 is inserted into the mounting groove 301 through the notch of the mounting groove 301. During this process, the bracket 35 will squeeze the body 30 around the mounting groove 301 to deform, until the bracket 35 is completely installed in the mounting groove 301, and the body 30 is restored to a natural state by deformation, and the bracket is limited to the body 30 and conflicts with the circuit board. The body 30, the bracket 35 and the connector 20 of the belt body of this embodiment can be replaced, which is convenient for the maintenance of the belt body 100.

[0131] The above are only some embodiments and implementation methods of the present application, and the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by any person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
