[0051] In order to enable those skilled in the art to better understand the scheme of the present application, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be noted that the descriptions of "first", "second", etc. in this article are used to distinguish different messages, devices, modules, etc., do not represent the order of precedence, and do not limit the "first" and "second" to different types; in addition, the following embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0052] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5a A schematic diagram of the belt structure of a wearable device provided by an embodiment of the present application is shown. Figure 1 As shown, the belt structure includes: a flexible belt 1, an intermediate component 2 and a flexible circuit board 3. The intermediate component 2 is arranged at one end of the flexible belt 1. The flexible circuit board 3 has a display element 31. The intermediate component 2 is arranged at the periphery of the flexible circuit board 3, and at least part of the flexible circuit board 3 is covered in the intermediate component 2; the intermediate component 2 is provided with a light-transmitting structure 23 at a position corresponding to the display element 31.

[0053] Figure 1 A schematic diagram showing a first viewing angle of the belt structure; Figure 2 A schematic diagram showing a second viewing angle of the belt structure; Figure 3 A schematic diagram showing a third viewing angle of the belt structure; Figure 4 for Figure 3 Section view from medium AA perspective; Figure 5a An exploded schematic diagram of the belt structure is shown.

[0054] One end of the intermediate member 2 can be connected to the end of one end of the flexible belt 1, that is, the intermediate member 2 and the flexible belt 1 are connected in sequence. Figures 1 to 5a The intermediate member is shown partially housed within the end of the flexible band, with a portion exposed.

[0055] For the sake of aesthetics and shielding the flexible circuit board, the middle piece 2 should be made of a non-transparent material. If the middle piece 2 is connected to the flexible belt 1 in sequence, the middle piece 2 and the flexible belt 1 can be of the same color or pattern. Figures 1 to 5a The structural part shown is located inside the flexible belt 1 . In order to ensure the display effect of the display element, the flexible belt 1 should be made of a light-transmitting material, or even a completely transparent material. Figure 5b The flexible tape is shown to be transparent, and the middle piece wrapped inside is non-transparent to shield the flexible circuit board.

[0056] In specific implementation, the flexible circuit board 3 may be provided with a power supply battery and a control circuit, so that there is no need to provide an electrical connection portion connected to external electronic components. If the flexible circuit board needs to be powered and controlled by components other than the body structure (such as the body of a wearable device), the flexible circuit needs to have an electrical connection portion 32, such as Figures 1 to 5b As shown, the electrical connection portion 32 is exposed to the outside, so that when the device body and the belt body structure are subsequently assembled, the exposed electrical connection portion 32 is electrically connected to the main circuit of the device body of the wearable device to obtain control signals and power supply energy.

[0057] The technical solution provided in this embodiment is to achieve the effect of the belt body of the wearable device having a luminous or pattern display effect. An intermediate piece is arranged at one end of the flexible belt. The intermediate piece is arranged at the periphery of the flexible circuit board to cover at least part of the flexible circuit board, and a light-transmitting structure is provided at a position of the intermediate piece corresponding to the display element, which ensures the display effect of the display element while also shielding the flexible circuit board. In specific implementation, the intermediate piece can be prepared in various colors for an aesthetic appearance. The flexible belt can meet the requirements of wearing and bending.

[0058] In a specific implementation, the display element 31 may be an electronic display screen or an LED array (eg Figure 5a ). More specifically, the LED array includes a plurality of LED lamp beads arranged in an array. The plurality of LED lamp beads may be arranged in a line, or in multiple rows and columns, or in a regular pattern, etc., and this embodiment does not specifically limit this. Among them, the multiple rows and columns arrangement may include: horizontal and vertical row alignment arrangement, horizontal row staggered arrangement, vertical row staggered arrangement, etc. The regular pattern arrangement may include: star pattern arrangement, heart pattern arrangement, flower pattern arrangement, wave pattern arrangement, etc.

[0059] In this embodiment, the middle piece 2 is molded into an integral structure with the flexible circuit board 3 through an injection molding process; or the flexible belt 1 is molded into an integral structure with the middle piece 2 through an injection molding process; or the middle piece 2, the flexible belt 1 and the flexible circuit board 3 are molded into an integral structure through an injection molding process.

[0060] See also Figure 5a As shown, the middleware 2 can be implemented with a two-stage structure. Figure 5a As shown, the middle piece 2 has a hard segment 21 and a flexible segment 22 arranged along the length direction of the flexible belt; the hard segment 21 is provided with a connection structure 24. By adding the hard segment 21 to the middle piece 2 and providing the connection structure 24 on the hard segment 21, the firmness of the connection can be improved when connected to the device body of the wearable device. For example, Figure 5a The connection structure 24 shown in the figure is a screw hole, and the belt structure is fixed to the device body of the wearable device by screws passing through the screw holes. If the screw holes are directly set on the flexible member, when the screws are fixed, the flexible material is not subjected to force on the structure after the screws are locked, which cannot meet the requirements of fastening and assembling the belt structure and the device body of the wearable device.

[0061] See also Figure 4 and Figure 5a In the example shown, the flexible belt 1 covers the flexible section 22, and the hard section 21 can be partially covered in the flexible belt 1 or completely exposed outside the flexible belt 1. Figure 6 and Figure 7In the example shown, the belt surface at one end of the flexible belt 1 covers the flexible section. Figure 7 As shown, the belt surface at one end of the flexible belt 1, i.e. Figure 7 The concave surface 11 at one end of the flexible belt 1 is shown to cover the flexible section 22. Of course, this covering is formed by injection molding. For example, the flexible belt 1 is formed by injection molding on the flexible section 22 to produce the following: Figure 7 The structure shown.

[0062] Since the flexible belt 1 will cover or wrap the flexible segment 22, when a light-transmitting structure is provided on the flexible segment, in order to avoid blocking the display element 31, the material of the flexible belt 1 needs to be a transparent material so that the display content of the display element 31 can be seen, such as a pattern or text composed of multiple LED lamp beads, or a pattern or text to be displayed on the display screen.

[0063] Further, such as Figure 4 and Figure 5a As shown, at least part of the hard segment 21 exceeds the end of the flexible belt 1, that is, the hard segment 21 can be completely exposed outside the flexible belt 1; or part of the hard segment 21 can be inside the flexible belt 1, and the rest of the hard segment 21 can be exposed outside the flexible belt 1. Figure 6 and Figure 7 The structure shown is that the hard segment 21 and the flexible segment 22 partially overlap, and the overlapping portion and the flexible segment 22 are wrapped in the flexible belt; the remaining portion of the hard segment 21 is exposed outside.

[0064] In the technical solution provided in this embodiment, the specific implementation structure of the middleware and the flexible belt can be implemented using two solutions. Figures 1 to 5a A first approach is shown. Figure 6 and Figure 7 A second approach is shown.

[0065] Specific:

[0066] The first option

[0067] join Figure 4 and Figure 5a As shown, the end of the flexible belt 1 has an opening 13 of the accommodation space 12; the flexible section 22 of the middle piece 2 is located in the accommodation space 12; the hard section 21 of the middle piece 2 is located at the opening 13 and is at least partially exposed to the outside. Figure 8 As shown, the rigid segment 21 may include a first rigid body 211 and a second rigid body 212. The first rigid body is connected to the flexible segment 22; the second rigid body 212 is a portion extending from one end of the first rigid body 211 away from the flexible segment 22 along a direction. Figure 8As shown, the direction may be the x direction in the figure, and the length direction of the flexible belt 1 is the y direction in the figure. The direction and the length direction of the flexible belt 1 have an angle. The specific value of the angle is not specifically limited in this embodiment. The angle is related to the connection design between the belt structure and the device body of the wearable device. In specific implementation, the angle can be determined based on specific design requirements. Figure 8 In the example shown, the angle may be an obtuse angle. The second rigid body 212 is provided with the connection structure 24. The connection structure 24 may be a through hole, a threaded hole, or the like.

[0068] See also Figure 5a As shown, the end of the flexible belt 1 is provided with a protruding portion 14 adapted to the second rigid body 212; the protruding portion 14 is provided with an adapting structure 141 at a position corresponding to the connecting structure 24. That is, when the connecting structure 24 is a through hole, the adapting structure can be a through hole of the same size and coaxial; when the connecting structure 24 is a threaded hole, the adapting structure can be a through hole of the same size and coaxial. Since the flexible belt 1 is made of a flexible material, the protruding portion 14 is also made of a flexible material, and when the belt structure is fixedly connected to the device body of the wearable device using screws, it can play the role of a gasket and play a role of relaxation.

[0069] Furthermore, the flexible belt 1 is divided into an inner side and an outer side; the protruding portion 14 is a bending structure extending from the inner end of the flexible belt 1 in a direction away from the outer side of the flexible belt 1. The difference between the inner side and the outer side here is related to the state of the flexible belt 1 when it is worn. For example, if the flexible belt is a bracelet worn on the wrist, then the inner side is the side close to the wearer's arm, and the outer side is the side facing away from the wearer's arm, which is the side visible to the wearer. Of course, the content displayed by the display element needs to be displayed through the outer side of the flexible belt 1. The bending structure extending from the inner end of the flexible belt 1 in a direction away from the outer side of the flexible belt 1 makes the integrity of the inner side of the flexible belt better, which helps to improve the wearing comfort.

[0070] Second option

[0071] See also Figure 6 and Figure 7 As shown, the flexible section includes: a first side flexible body 221 and a second side flexible body 222. The first side flexible body 221 is in contact with the belt surface of the flexible belt 1, that is, Figure 7 As shown, the first side flexible body 221 is fitted with the concave surface of the end of the flexible belt 1. The fitting here can be formed by an injection molding process. For example, the flexible belt 1 is formed by injection molding on the first side flexible body 221 through an injection molding process. Further, the hard segment 21 is located on the first side flexible body 221. The hard segment 21 and the first side flexible body 221 can partially overlap.

[0072] Continue to see Figure 6 As shown, the flexible segment 22 can cover part of the flexible circuit board 3 inside; and the hard segment 21 half covers the remaining part of the flexible circuit board 3 .

[0073] The belt structure provided in this embodiment can be connected to a dial (such as a mechanical dial, a smart watch dial) or the like. Specifically, the belt structure is provided with a connection structure, and the belt structure is connected to the dial through the connection structure to form a watch with a display effect (such as luminescence, pattern display, etc.) on the strap. Alternatively, the same dial can be equipped with a variety of belt structures with display effects, and users can regularly replace belt structures with different display effects according to their preferences.

[0074] Fig. 9 and Fig.10 FIG. 1 is a schematic diagram showing the structure of a wearable device provided by an embodiment of the present application. Fig. 9 and Fig.10 As shown, the wearable device includes: a device body 100 and a belt structure 200. The belt structure 200 may be two. Fig. 9 and Fig.10 It can be seen from the orientation of the figure that the upper parts of the two belt structures 200 (i.e., the parts connected to the device body 100) have the same structure. The lower parts of the two belt structures 200 use different connection methods, and the corresponding structures will be different. For example, Fig. 9 and Fig.10 In the connection method shown, the two belt structures 200 are connected by means of nail buckles, one of the belt structures 200 is provided with a nail buckle 4, and the other belt structure 200 is provided with at least one nail hole 5; the connection can be achieved by buckling the nail buckle 4 into the nail hole 5. Of course, the two belt structures 200 can also be connected by other methods, which can be specifically referred to the connection methods of existing watch straps, and will not be listed one by one in this article.

[0075] Alternatively, there may be only one belt structure 200, and an elastic part is provided on the belt structure 200 so that the belt structure can be stretched. The structures at both ends of the belt structure 200 may be the same, except that the positional relationship between the components is a mirror image relationship.

[0076] See also Figures 1 to 7 As shown, the belt structure includes a flexible belt 1, an intermediate component 2 and a flexible circuit board 3. The intermediate component 2 is arranged at one end of the flexible belt. The flexible circuit board 3 has a display element 31. The intermediate component 2 is arranged at the periphery of the flexible circuit board 3, covering at least part of the flexible circuit board 3; a light-transmitting structure 23 is provided at a position of the intermediate component 2 corresponding to the display element 31. The flexible circuit board 3 also has an electrical connection portion 32 electrically connected to the device body.

[0077] Furthermore, the middle piece 2 has a hard segment 21 and a flexible segment 22 arranged along the length direction of the flexible belt; the hard segment 21 is exposed at the end of the flexible belt 1; a connecting structure 24 is provided on the hard segment 21, and the connection between the hard segment 21 and the equipment body 100 is achieved through the connecting structure 24.

[0078] Specifically, Figures 1 to 5b As shown, when the belt structure adopts the structure shown in the figure (the specific structure can be found in the corresponding description of the first scheme above, which will not be repeated here), the connecting structure 24 is a threaded hole. The device body 100 includes an upper cover 101, a lower cover 102 and a main body 103. The main body 103 may include but is not limited to: a main circuit board, a main display element (such as a display screen or an LED array) arranged on the main circuit board, a sensor (such as a gyroscope, a gravity sensor, etc.), a Wi-Fi / NFC network module, a vibration motor, a charging circuit, a charging interface, a battery, a bracket assembly for installing or assembling the aforementioned electronic components, and the like. The main body 103 is accommodated between the upper cover 101 and the lower cover 102. The upper cover 101 and the lower cover 102 can be buckled together using a snap-on structure. The assembly process may include:

[0079] S11, insert the main body 103 into the upper cover 101;

[0080] S12, inserting the electrical connection portion 32 on the flexible circuit board 3 of the belt structure 100 into the main circuit board interface; assembling and pressing the hard section 21 of the middle piece 2 of the belt structure 100 with the lower cover 102;

[0083] When the belt structure adopts Figure 6 and Figure 7 When the structure shown in FIG. 1 is used (the specific structure can be found in the corresponding description of the second solution above, which will not be described here in detail), the inner buckle fixing member 7 is used to fix the belt structure 200 to the device body. Fig.11 As shown, the wearable device provided in this embodiment further includes an inner buckle fixing member 7. The inner buckle fixing member 7 is provided with a matching structure 71 adapted to the connection structure 24; the connection between the hard segment 21 and the device body is achieved by using the matching connection structure 24 and the matching structure 71. Specifically, the connection structure 24 and the matching structure 71 can be screw holes. Fig.11As shown, the device body has the same structure as described above, namely, it includes an upper cover 101, a lower cover 102 and a main body 103. The assembly process may include:

[0084] S11, insert the main body 103 into the upper cover 101;

[0087] S14, press the lower cover 102 and the upper cover 101 together by means of a snap-fit ​​structure to complete the assembly of the whole machine.

[0088] For further information, see Fig. 9 and Fig.10 As shown, the device body is provided with a shell structure 1011 extending toward the flexible belt 1; the hard segment 21 is placed in the shell structure 1011, and after being connected to the device body through the connecting structure 24, the outer surface of the shell structure 1011 is flush with the outer surface of the flexible belt 1; the shell structure 1011 is provided with a light-transmitting structure (such as Fig.11 Alternatively, the housing structure 1011 is made of a transparent material, and the display element corresponding to the hard segment 21 placed in the housing structure 1011 can be displayed through the housing structure 1011.

[0089] The outer surface of the shell structure 1011 is flush with the outer surface of the flexible band 1, making the overall appearance of the wearable device more beautiful and simple.

[0090] It should be noted here that: for the two implementation schemes of the belt structure, please refer to the corresponding contents in the above embodiments, which will not be repeated here.
