[0002] In recent years, wearable electronic devices (hereinafter referred to as wearable devices), such as smart watches and smart bracelets, have gradually emerged. As the functions of wearable devices become more and more, more and more functional devices are integrated in the main body of the wearable device (for example, the dial of a smart watch). For example, a solar module can be added to the main body of the wearable device to increase the battery life. However, too many functional devices will make the main body of the wearable device larger, affecting the comfort of the user. Generally speaking, wearable devices have a fixing belt to help users wear them. Placing a part of the functional devices in the fixing belt helps to reduce the volume of the main body. However, how to achieve a reliable connection between the fixing belt and the main body has become a problem that needs to be solved urgently. Summary of the invention

In addition, in order to facilitate the clear description of the technical solution of this application, the words "first" and "second" are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first" and "second" do not limit the quantity and execution order, and the words "first" and "second" do not limit them to be different.

[0101] The wearable device, watch strap and watch dial provided in the embodiments of the present application are explained in detail below.

[0102] See also Figure 1and Figure 2 As shown, Figure 1 is a schematic diagram of the structure of a wearable device in an embodiment of the present application, Figure 2 It is a schematic diagram of the structure of another wearable device in an embodiment of the present application.

[0103] In one or more embodiments, the wearable device provided in the present application can be worn on the user, for example, on the user's wrist, arm, neck, finger or head. Accordingly, the wearable device can be a smart watch 100 / smart bracelet, armband, collar, finger ring, head-mounted display (HMD), etc. The present application does not limit the specific type of wearable device. Specifically, the wearable device may include a device body 101 and a fixing belt 102. Among them, the fixing belt 102 is connected to the device body 101. As shown in the figure, in the present application, the width direction of the fixing belt 102 is defined as the AA direction, and the length direction of the fixing belt when straightened is defined as the LL direction, and the length direction of the fixing belt when straightened is perpendicular to the width direction. The device body 101 may include a housing and a display screen, the display screen is mounted on the housing, and the display screen is used to display text information and / or image information to the user; the housing is also equipped with necessary components of the wearable device, such as a main board, etc.; the main board may have a controller for realizing the control of the display screen and the integrated functional module in the fixing belt 102. In the present application, the wearable device is taken as a watch 100, and the wearable device body is the dial of the watch 100. Thus, the dial of the watch 100 includes a device body 101. The fixing band 102 can be the strap of the watch 100. The dial can be round (e.g. Figure 1 As shown), it can also be square (as Figure 2 As shown). It is understood that the shape of the dial is not limited thereto. The fixing belt 102 has a certain length, width and thickness; one end of the fixing belt in the length direction is connected to the device body.

[0104] It should be noted that the shell can also be called a middle frame; in the embodiment of the present application, the fixing belt 102 is installed on the device body 101, thereby realizing the connection between the fixing belt 102 and the device body 101; and the fixing belt 102 is removed from the device body 101, thereby realizing the disconnection (also called separation) between the fixing belt 102 and the device body 101.

[0105] Combination Figures 3 to 5 As shown, Figure 3 It is a schematic diagram of the local structure when the device body 101 is connected to the fixing belt 102 in the embodiment of the present application. Figure 4 It is a partial structural schematic diagram from another perspective when the device body 101 is connected to the fixing belt 102 in the embodiment of the present application. Figure 5It is a schematic diagram of the local structure when the device body 101 and the fixing belt 102 are separated in the embodiment of the present application.

[0106] In the present application, the thickness direction of the device body and the fixing belt is defined as BB direction, and the BB direction is perpendicular to the AA direction. Figure 3 and Figure 4 Schematic diagrams of different viewing angles after the fixing belt 102 is connected to the device body 101 are respectively shown.

[0107] See Figure 5 In some embodiments, the device body 101 may be provided with a first electrical connector 103 and a first limiting structure 104. The first electrical connector 103 and the first limiting structure 104 may be provided on the shell; correspondingly, the fixing belt 102 may be provided with a second electrical connector 105 and a second limiting structure 106. The second electrical connector 105 and the first electrical connector 103 may be detachably connected; at the same time, the first limiting structure 104 and the second limiting structure 106 may cooperate with each other so that the fixing belt 102 and the device body 101 may be detachably connected. The first electrical connector 103 and the second electrical connector 105 may be electrically connected by abutment or by plugging. For example, see Figure 5 As shown, the first electrical connector 103 may include a plurality of contact pieces 108 distributed at intervals; correspondingly, the second electrical connector 105 may include a plurality of pins 109 distributed at intervals. The plurality of contact pieces 108 are arranged in a one-to-one correspondence with the plurality of pins 109. When the fixing belt 102 is connected to the device body 101, the first limiting structure 104 will engage with the second limiting structure 106, that is, each pin 109 abuts against the corresponding contact piece 108, thereby achieving electrical connection between the first electrical connector 103 and the second electrical connector 105.

[0108] Furthermore, the wearable device may further include a trigger key 107 , that is, the wearable device body includes a trigger key 107 , and the trigger key 107 may be located on the device body 101 or on the fixing belt 102 . Figure 5 The trigger key 107 is shown as being installed on the device body 101. The trigger key 107 is located on a side parallel to the thickness direction of the device body 101. Figure 3 As shown, after the fixing belt 102 is connected to the device body 101, the trigger key 107 is located on one side of the fixing belt in the width direction. Figure 3As shown, the direction pointed by the arrow in FIG. 3 is the first direction F, which is the installation direction; the trigger key 107 can move along the pressing direction H after being pressed; wherein, pressing the trigger key 107 causes the fixing belt 102 to move along the first direction F relative to the device body 101, so that the first limiting structure 104 and the second limiting structure 106 stop each other, so that the fixing belt 102 is connected to the device body 101, and the first direction F is set at an angle to the pressing direction H of the trigger key 107. In this way, a reliable electrical connection between the fixing belt 102 and the device body 101 can be achieved. Figure 6 1 is a schematic diagram of a partial structure when the device body 101 is connected to the fixing belt 102 in the embodiment of the present application. Figure 6 , an angle α formed by the first direction F and the pressing direction H of the trigger key 107 is shown.

[0109] When some functional modules are installed in the fixing belt 102, these functional modules can be electrically connected to the second electrical connector 105. These functional modules can be one or more of a solar module, an ECG electrode module, a motion monitoring module, a sleep monitoring module, a blood pressure detection module, and a body fat detection module. Through the electrical connection between the first electrical connector 103 and the second electrical connector 105, the functional module can communicate with the controller in the device body 101. At the same time, through the mutual stop between the first limiting structure 104 and the second limiting structure 106, a reliable mechanical connection can be achieved between the fixing belt 102 and the device body 101 to ensure the reliability of the electrical connection between the first electrical connector 103 and the second electrical connector 105.

[0110] In addition, the trigger key 107 can also facilitate the disassembly and installation between the fixing belt 102 and the device body 101. Therefore, through the cooperation between the above-mentioned structures, when some functional modules in the wearable device are transferred to the fixing belt 102, the first limiting structure 104, the second limiting structure 106 and the trigger key 107 are used to achieve a reliable mechanical connection between the fixing belt 102 and the device body 101, thereby ensuring a reliable electrical connection between the first electrical connector 103 and the second electrical connector 105, so that the functional modules in the fixing belt 102 can work normally. In addition, since the first direction F is set at an angle to the pressing direction H of the trigger key 107, the user can achieve the connection between the fixing belt 102 and the device body 101 by pressing and moving along the first direction F, which has the characteristics of convenient operation; similarly, the user can press the trigger key 107 and move in the direction opposite to the first direction F to disassemble the fixing belt 102 from the device body 101.

[0111] In addition, since the functional modules can be integrated into the fixing band 102, the functions of the wearable device are greatly expanded. The user can even replace different fixing bands 102 as needed, and different functional modules can be integrated into different fixing bands 102. In this way, by matching the device body 101 with the fixing bands 102 with different functional modules, the functions of the wearable device can be further diversified.

[0112] Figure 6 1 is a schematic diagram of a partial structure when the device body 101 is connected to the fixing belt 102 in the embodiment of the present application. Figure 7 is along Figure 6 Cross-sectional view of the CC line in FIG. Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the first limiting structure 104 and the second limiting structure 106 can be connected by engaging with each other. During the connection between the fixing belt 102 and the device body 101, the fixing belt 102 presses the trigger key 107, and then the fixing belt 102 moves along the first direction F, so that the first limiting structure 104 and the second limiting structure 106 are engaged. When the fixing belt 102 moves relative to the device body 101, when the fixing belt 102 no longer abuts against the trigger key 107, the trigger key 107 returns to its original position, and the edge of the trigger key 107 stops the fixing belt 102 to prevent the fixing belt 102 from moving in the direction opposite to the first direction F, thereby achieving a reliable connection between the fixing belt 102 and the device body 101.

[0113] Figure 8 yes Figure 6 The left view of Fig. 9 is along Figure 8 The cross-sectional view of the GG line in Fig. 9 It can be seen from the figure that the fixing belt 102 is inserted into the device body 101, so that the left and right wings of the ends of the fixing belt 102 in the length direction can be stopped by the device body 101 and the trigger key 107. When the first limiting structure 104 and the second limiting structure 106 are separated, the fixing belt 102 and the device body 101 are separated.

[0114] Further, the trigger key 107 is used as a button to realize the combination or separation between the first limiting structure 104 and the second limiting structure 106. When the fixing belt 102 is connected to the device body 101, the trigger key 107 is pressed first, and then the fixing belt 102 is moved relative to the device body 101 for a distance, and the first limiting structure 104 is engaged with the second limiting structure 106. Finally, the trigger key 107 is released, so that the fixing belt 102 is convenient for connecting with the device body 101, and due to the blocking effect of the trigger key 107, the first limiting structure 104 and the second limiting structure 106 will not be separated. When the fixing belt 102 is separated from the device body 101, the trigger key 107 is pressed first, and then the fixing belt 102 is moved in the direction opposite to the installation direction for a distance, and the first limiting structure 104 is separated from the second limiting structure 106, and finally the trigger key 107 is released, so that the fixing belt 102 is convenient for separating from the device body 101. The movement trajectory of the fixing belt 102 when connecting or separating with respect to the device body 101 can be the following two situations:

[0115] In the first case, when the fixing belt 102 is connected to or separated from the device body 101, the movement trajectory of the fixing belt 102 relative to the device body 101 can be an arc or an approximate arc. In this case, the fixing belt 102 is rotated relative to the device body 101 to achieve connection or separation, and the corresponding first direction F can point to the rotation direction of the fixing belt 102 relative to the device body 101, so the first direction F is an arc or an approximate arc; in this case, when the movement trajectory of the trigger key 107 along the pressing direction H is a straight line, the angle α formed by the pressing direction H of the trigger key 107 and the first direction F is: the angle between the extension line J of the movement trajectory of the trigger key 107 along the pressing direction H and the tangent K at a set point on the movement trajectory of the fixing belt 102 relative to the device body 101, and the set point is the intersection O of the extension line J of the movement trajectory of the trigger key 107 along the pressing direction H and the movement trajectory of the fixing belt 102 relative to the device body 101, see Figure 6 shown.

[0116] In the second case, when the fixing belt 102 is connected to or separated from the device body 101, the movement trajectory of the fixing belt 102 relative to the device body 101 can be a straight line. In this case, the fixing belt 102 moves linearly relative to the device body 101 to achieve connection or separation, and the corresponding first direction F points to the direction of the linear movement of the fixing belt 102 relative to the device body 101. Therefore, the first direction F is a straight line or an approximate straight line. In this case, when the movement trajectory of the trigger key 107 along the pressing direction H is a straight line, the angle α formed between the pressing direction H of the trigger key 107 and the first direction F is: the angle between the extension line J of the movement trajectory of the trigger key 107 along the pressing direction H and the set point on the linear movement trajectory of the fixing belt 102 relative to the device body 101. The set point is the intersection of the extension line J of the movement trajectory of the trigger key 107 along the pressing direction H and the linear movement trajectory of the fixing belt 102 relative to the device body 101.

[0117] It should be noted that in the above two cases, the movement trajectory of the fixing belt 102 relative to the device body 101 and the movement trajectory of the trigger key 107 along the pressing direction H may not intersect in space, so the movement trajectory of the trigger key 107 along the pressing direction H or the extension line of the movement trajectory of the trigger key 107 along the pressing direction H can be translated to the starting position of the movement trajectory of the fixing belt 102 relative to the device body 101, so that the intersection point after the intersection is the set point. The starting position of the movement trajectory of the fixing belt 102 relative to the device body 101 can refer to the starting position of the fixing belt 102 rotating relative to the device body 101 to achieve the connection process.

[0118] When the watch 100 is a round watch, the dial is round or approximately round. When the fixing band 102 is connected or separated from the device body 101, the fixing band 102 can be rotated relative to the device body 101 for a certain distance around the circumference of the device body 101 to achieve connection or separation. Exemplarily, the connection process between the fixing band 102 and the device body 101 is: press the trigger key 107, then push the fixing band 102 from the trigger key 107 into the device body 101, and then move the fixing band 102 along the first direction F. When it moves to the position, the trigger key 107 automatically pops up. In this way, the fixing band 102 and the device body 101 can be effectively fixed in a limited space by the rotation of the trigger key 107 and the fixing band 102, and this operation method has the characteristics of convenient operation.

[0119] When the watch 100 is a rectangular watch, the dial is rectangular or approximately in a length shape. When the fixing band 102 is connected or separated from the device body 101, the fixing band 102 can be moved along a straight line along one side of the device body 101 relative to the device body 101 to achieve connection or separation, that is, the connection between the fixing band 102 and the device body 101 is achieved by pushing left and right. After the trigger key 107 is pressed, its moving direction is non-parallel to the first direction F, which can improve the stability of the connection between the fixing band 102 and the device body 101. The trigger key 107 can be installed on the device body 101 as needed, or it can be installed on the fixing band 102.

[0120] It should be noted that when the first electrical connector 103 adopts a plurality of spaced contact pieces 108 and the second electrical connector 105 adopts a plurality of spaced pins 109, the first electrical connector 103 may also be mounted on the fixing band 102, while the second electrical connector 105 may be mounted on the device body 101. In addition, when the watch 100 is a round watch, the connection or separation may also be achieved by moving in a straight line along one side of the device body 101.

[0121] Fig.10 1 is a partial structural diagram of the device body 101 in the embodiment of the present application when the trigger key 107 is installed on the device body 101. In some embodiments, the trigger key 107 can be set on the device body 101, which is conducive to reducing the cost of the fixing belt 102, and because the trigger key 107 is set on the device body 101, the fixing belt 102 can be used to press the trigger key 107 during installation and removal, so as to facilitate installation.

[0122] Specifically, the first electrical connector 103 has a first side 110 and a second side 111 opposite to each other, and the first side 110 or / and the second side 111 are provided with a trigger key 107, so that when the trigger key 107 is only installed on the first side 110 or the second side 111, the production cost can be reduced; and when the trigger key 107 is installed on both sides, whether the watch 100 is worn on the left hand or the right hand, the fixing band 102 can be easily connected and separated from the device body 101. The first direction F is the direction from the trigger key 107 to the first electrical connector 103, so as to facilitate pressing the trigger key 107 first, and then moving along the first direction F to achieve connection or disassembly between the first limiting structure 104 and the second limiting structure 106.

[0123] In some embodiments, the first side 110 and the second side 111 are further provided with a first limiting structure 104, respectively. After the first limiting structures 104 are provided on the first side 110 and the second side 111, respectively, when the first limiting structures 104 on the first side 110 and the second side 111 are respectively engaged with the second limiting structures 106 at the corresponding positions on the fixing belt 102, the fixing belt 102 and the device body 101 can be installed, so that both ends of the fixing belt in the width direction are fixed to the device body 101, which is conducive to improving the stability of the connection between the fixing belt 102 and the device body 101. The number of the first limiting structures 104 provided on the first side 110 or the second side 111 can be set as needed, for example, one first limiting structure 104 can be provided on each side. Of course, in some other possible embodiments, the number of the first limiting structures 104 provided on the first side 110 or the second side 111 can also be 2 or 3, and in addition, the number of the first limiting structures 104 provided on each side can be unequal.

[0124] Continue to see Fig.10 In some embodiments, the direction from the first side 110 to the second side 111 is perpendicular to the thickness direction of the device body 101; at least one first limiting structure 104 is located between the trigger key 107 and the first electrical connector 103. In this way, the first direction F is perpendicular to the thickness direction of the device body 101, which facilitates the connection between the device body 101 and the fixing belt 102. In one embodiment, the number of the trigger key 107 is one, and the trigger key 107 is located on the first side 110. The direction from the first side 110 to the second side 111 is the trigger key 107, the first limiting structure 104, and the first electrical connector 103 in sequence, that is, the trigger key 107 and the first limiting structure 104 are both located on the first side 110 of the first electrical connector 103, and the second side 111 has another first limiting structure 104. In this way, when only one first limiting structure 104 is provided on the first side 110 and the second side 111 respectively, the first electrical connector 103 is located between the two first limiting structures 104 in the direction from the first side 110 to the second side 111. In the direction from the first side 110 to the second side 111, the plurality of contact pieces 108 are distributed at intervals; and since the contact pieces 108 are installed on the device body 101, when the device body 101 is designed, the device body 101 may have a first mounting surface, and the first mounting surface may be in the form of a plane. When the first mounting surface is a plane, that is, the first mounting surface is a first docking plane, the first electrical connector 103 is located on the first docking plane, and the plurality of contact pieces 108 may be arranged along a straight line on the first docking plane.

[0125] Fig.11 is a partial structural diagram of the device body 101 in the embodiment of the present application when the trigger key 107 is not installed. Fig.12 yes Fig.11 A schematic diagram of a partial structure of the device body 101 from another perspective, Fig.13 yes Fig.12 The local enlarged schematic diagram of D in the middle, combined with Figure 7 , Fig.11 , Fig.12 and Fig.13 As shown, in some embodiments, the first limiting structure 104 includes a first limiting block 113, and a first limiting groove 114 is formed between the first limiting block 113 and the device body 101; the second limiting structure 106 includes a second limiting block 115, and the second limiting block 115 is configured to connect the fixing belt 102 with the device body 101 by moving into the first limiting groove 114. In this way, the fixing belt 102 and the device body 101 are reliably connected by using the trigger key 107 to cooperate with the second limiting block 115 to move to the first limiting groove 114; after the second limiting block 115 moves to the first limiting groove 114, the second limiting block 115 cannot move in a direction parallel to the pressing direction H of the trigger key 107, so that after the first limiting structure 104 and the second limiting structure 106 are locked, the fixing belt 102 is stopped in a direction parallel to the pressing direction H of the trigger key 107, and the fixing belt 102 cannot be separated from the device body 101. Furthermore, after the trigger key 107 is released from the external force, the trigger key 107 also limits the movement of the second limit block 115 in the first direction F, so that the second limit block 115 cannot move out of the first limit groove 114 along the first direction F, thereby achieving the first limit structure 104 and the second limit structure 106 being stopped in the first direction F; and then by stopping the first limit structure 104 and the second limit structure 106 in the first direction F in a direction parallel to the pressing direction H of the trigger key 107, the detachable connection between the fixing belt 102 and the device body 101 is achieved. It should be noted that the first limit structure 104 and the second limit structure 106 are not limited to the way in which the second limit block 115 cooperates with the first limit groove 114, but can also be achieved in other possible ways.

[0126] In some embodiments, the first limiting structure 104 includes two first limiting blocks 113, and the two first limiting blocks 113 are spaced apart in the thickness direction of the device body 101. This facilitates the design of the specific form of the second limiting structure 106.

[0127] See also Fig.11As shown, in one embodiment, the side surface of the device body 101 in the thickness direction has a mounting groove 116, and the bottom of the mounting groove 116 forms a first mounting surface. In addition, the first limiting structure 104 is arranged in the mounting groove 116, and the length extension direction of the mounting groove 116 is consistent with the length extension direction of the first mounting surface, and the two ends of the length direction of the first mounting surface respectively have assembly grooves 117. Specifically, a recess is set at the bottom of the mounting groove 116 to form the assembly groove 117. By setting the mounting groove 116, the first limiting structure 104 and the trigger key 107 can be set on the device body 101 through the mounting groove 116. In this way, from the appearance, the device body 101, the first limiting structure 104 and the trigger key 107 are compactly integrated, so that the wearable device looks relatively small. The first limiting block 113 is located in the assembly groove 117, and the space between the bottom of the assembly groove 117 and the first limiting block 113 forms the first limiting groove 114. The two first limiting blocks 113 in each first limiting structure 104 are respectively located on the upper and lower groove walls of the assembly groove 117; along the length direction of the installation groove 116, the first limiting block 113 is located in the middle position of the groove wall of the assembly groove 117, so that along the length direction of the installation groove 116, the first limiting block 113 has a receiving space 118 on both opposite sides, and the receiving space 118 is a part of the assembly groove 117. In the process of assembling the fixing belt 102 with the device body 101, the second limiting block 115 is first inserted into the receiving space 118, and then when the fixing belt 102 moves relative to the device body 101, the second limiting block 115 slides from the receiving space 118 into the first limiting groove 114. It should be noted that in order to achieve the connection between the fixing belt 102 and the device body 101, the end of the fixing belt 102 can be inserted (or plugged into) the installation groove 116. In order to ensure waterproof performance, there can be no gap after the end of the fixing belt 102 is inserted into the installation groove 116.

[0128] See also Fig.13As shown, in some implementations, the device body 101 has a first guide groove 119 to enable the trigger key 107 to move in a directional manner along the pressing direction H; the bottom of the mounting groove 116 has a blind hole 120, which may be a circular hole; the hole wall of the blind hole 120 is formed with a first guide groove 119, and the number of the first guide grooves 119 may be one or more. Exemplarily, the number of the first guide grooves 119 is two, and the two first guide grooves 119 are symmetrically arranged. In the axial direction of the blind hole 120, the starting position of the first guide groove 119 is located at the bottom of the blind hole 120; and the length of the first guide groove 119 in the axial direction of the blind hole 120 is less than the depth of the blind hole 120, so that the trigger key 107 is limited to the device body 101 and can move relative to the device body 101. It should be noted that in some other possible implementations, the blind hole 120 can also be a polygonal hole, such as a square hole.

[0129] Fig.14 is a schematic diagram of the structure of the trigger key 107 in the embodiment of the present application, Fig.15 1 is a schematic diagram of the structure of the key body 121 in the embodiment of the present application. In some embodiments, the trigger key 107 includes a key body 121 and an elastic member 122. The key body 121 is limited on the device body 101; one end of the elastic member 122 abuts against the key body 121, and the other end of the elastic member 122 abuts against the device body 101, so that after the force applied to the key body 121 is removed, the key body 121 can return to its original position; in this way, the elastic member 122 is used to realize that the key body 121 can be pressed. When the external force is removed, it can automatically return to its original state, thereby facilitating the connection between the fixing belt 102 and the device body 101. In one embodiment, the elastic member 122 is located in the blind hole 120, one end of the elastic member 122 abuts against the key body 121, and the other end of the elastic member 122 abuts against the bottom of the blind hole 120. When the pressing force on the key body 121 is removed, the elastic member 122 restores the key body 121 to the position before being pressed, thereby returning it to its original position; the elastic member 122 may be a spring, which may well return the key body 121 to its original position. It should be noted that in some other possible implementations, the elastic member 122 may also be elastic plastic, etc.

[0130] Furthermore, combined with Fig.13 , Fig.14 and Fig.15As shown, in some embodiments, the key body 121 includes a panel structure 123 and a guide structure 124, the guide structure 124 is connected to one side of the panel structure 123, and the guide structure 124 has a first mounting hole 125, one end of the elastic member 122 is inserted into the first mounting hole 125; the guide structure 124 is limited in the first guide groove 119. The first mounting hole 125 is provided to facilitate the installation of the elastic member 122, and the first guide groove 119 is provided to facilitate the movement path of the key body 121 to be a straight line. The panel structure 123 has a large pressing surface to facilitate the user to press the key body 121. The guide structure 124 includes a columnar structure 126 and a guide wing 127, the number of the guide wing 127 can be one or more, and the exemplary number of the guide wing 127 is two, and the two guide wings 127 are symmetrically distributed on the columnar structure 126. The first mounting hole 125 is located on the columnar structure 126, and the hole depth of the first mounting hole 125 extends along the axial direction of the columnar structure 126. The radial cross-section of the columnar structure 126 can be circular to match the blind hole 120; the first mounting hole 125 can have a mounting column 128, one end of the mounting column 128 is fixedly connected to the panel structure 123, and the other end of the mounting column 128 does not extend out of the opening of the first mounting hole 125. The mounting column 128 is inserted into the spring, and the length of the mounting column 128 is smaller than the length of the spring, so that after the button body 121 is installed on the device body 101, the button body 121 can move relative to the device body 101. The pressing direction H of the button body 121 is parallel to the axial direction of the columnar structure 126; one end of the columnar structure 126 is fixedly connected to the panel structure 123, and the guide wing 127 is located at the other end opposite to the columnar structure 126; the guide wing 127 extends into the first guide groove 119, and the columnar structure 126 is inserted into the blind hole 120. Since the length of the first guide groove 119 in the axial direction of the blind hole 120 is less than the depth of the blind hole 120, the guide wing 127 ensures that the guide structure 124 is not easy to fall off the device body 101, thereby limiting the button body 121 to the device body 101. The travel distance of the button body 121 relative to the device body 101 is determined by the length of the first guide groove 119 in the axial direction of the blind hole 120; after the guide wing 127 is inserted into the first guide groove 119, the thickness of the guide wing 127 in the axial direction of the blind hole 120 is smaller than the length of the first guide groove 119 in the axial direction of the blind hole 120, so that the guide wing 127 can move along the first guide groove 119 in the axial direction of the blind hole 120; when the button body 121 is installed on the device body 101, the axial direction of the blind hole 120 is parallel to the axial direction of the columnar structure 126.

[0131] In some embodiments, the material of the guide wing 127 can be an elastic material, that is, it can be deformed under extrusion. In this way, during the assembly process, the guide wing 127 can be inserted into the first guide groove 119 with force. When it is necessary to make the guide wing 127 have a certain elasticity, the entire key body 121 can be made of hard plastic, such as a material obtained by adding glass fiber to polycarbonate, or a material obtained by adding glass fiber to nylon, or a material obtained by adding glass fiber to polybutylene terephthalate. When it is necessary to make the guide wing 127 have better elasticity relative to the panel structure 123, the panel structure 123 and the guide wing 127 can be made of different materials, and the panel structure 123 and the guide wing 127 can be realized by using double-shot injection molding or in-mold injection molding and other process solutions. Of course, the guide wing 127 and the panel structure 123 can also be combined together by dispensing glue, back glue, welding and other solutions.

[0132] In some embodiments, the other side surface opposite to the panel structure 123 may be a flat surface or a curved surface, respectively adapted to the appearance of a rectangular watch and a round watch.

[0133] The structure of the fixing belt is described in detail below. Fig.16 is a schematic diagram of a partial structure of the fixing belt 102 in the embodiment of the present application, Fig.17 It is a top view of the local structure of the fixing belt 102 in the embodiment of the present application.

[0134] In some embodiments, the second electrical connector 105 has a third side 129 and a fourth side 130 opposite to each other, and the third side 129 and the fourth side 130 are respectively provided with a second limiting structure 106. The first limiting structure 104 located on the first side 110 cooperates with the second limiting structure 106 located on the third side 129; the first limiting structure 104 located on the second side 111 cooperates with the second limiting structure 106 located on the fourth side 130. In this way, the second limiting structure 106 is respectively provided on the third side 129 and the fourth side 130 to improve the stability of the connection between the fixing belt 102 and the device body 101. The number of the second limiting structures 106 provided on the third side 129 or the fourth side 130 can be set as needed. For example, there can be one second limiting structure 106 on each side. The direction from the third side 129 to the fourth side 130 is perpendicular to the thickness direction of the fixing belt 102, that is, the direction from the third side 129 to the fourth side 130 is the width direction of the fixing belt 102. The plurality of pins 109 of the second electrical connector 105 are arranged in substantially the same direction from the third side 129 to the fourth side 130 .

[0135] Specifically, each second limiting structure 106 includes two second limiting blocks 115, and the two second limiting blocks 115 have a spacing in the thickness direction of the fixing belt 102 and are symmetrically arranged. The second limiting block 115 includes a clamping portion 131 and a base 132, the base 132 is connected to the fixing belt 102, the clamping portion 131 is connected to the base 132, and a clamping space 133 is formed between the clamping portion 131 and the fixing belt 102. During the assembly of the fixing belt 102 and the device body 101, the clamping portion 131 slides from the vacant space into the first limiting groove 114, so that the first limiting structure 104 and the second limiting structure 106 are clamped, and the first limiting block 113 slides into the clamping space 133, so that the first limiting structure 104 and the second limiting structure 106 are clamped. Since the pins 109 are mounted on the fixing belt 102, when designing the fixing belt 102, the fixing belt 102 may have a second mounting surface 134, and the second mounting surface 134 may be in the form of a plane. When the second mounting surface 134 is a plane, that is, the second mounting surface 134 is a second docking plane, the second electrical connector 105 is located on the second docking plane, and the plurality of pins 109 may be arranged along a straight line on the second docking plane, so that the second electrical connector 105 located on the second docking plane can be electrically connected to the first electrical connector 103 located on the first docking plane, and the first docking plane and the second docking plane are used, which is also convenient for manufacturing and improves the stability of the electrical connection between the first electrical connector 103 and the second electrical connector 105.

[0136] It should be noted that, in some other possible implementations, the number of second position limiting structures 106 respectively provided on the third side 129 or the fourth side 130 may also be 2 or 3, and the number of second position limiting structures 106 provided on each side may not be equal. In addition, the two second position limiting blocks 115 in each second position limiting structure 106 may be connected to form an integral structure, that is, there is no spacing between the two second position limiting blocks 115 in the thickness direction of the fixing belt 102.

[0137] Continue to see Fig.16 In some embodiments, the waterproof rubber ring 135 can be installed only on the fixing belt 102, and the waterproof rubber ring 135 is arranged around the circumference of the second electrical connector 105. The pin 109 is located in the waterproof rubber ring 135, so that after the first electrical connector 103 and the second electrical connector 105 are connected, the waterproof rubber ring 135 can ensure the stability of the electrical connection between the first electrical connector 103 and the second electrical connector 105, achieve waterproofing, and prevent liquid from flowing into the first electrical connector 103 and the second electrical connector 105, causing a short circuit. The waterproof rubber ring 135 can also wrap the circumference of the pin 109, so that the circumference of each pin 109 can be waterproofed to prevent liquid from flowing into the interior of the fixing belt 102 and affecting the functional module.

[0138] It should be noted that, in some other embodiments, the waterproof rubber ring 135 may be installed only on the device body 101 , and the waterproof rubber ring 135 may be arranged circumferentially around the first electrical connector 103 ; or, the waterproof rubber ring 135 may be installed on both the device body 101 and the fixing belt 102 .

[0139] Combination Figures 18 to 21 As shown, Fig.18 1 is a partial structural diagram of the embodiment of the present application when the waterproof rubber ring 135 is not installed on the fixing belt 102. Fig.19 1 is a state diagram of the fixing belt 102 pressing the trigger key 107 during the process of connecting the device body 101 with the fixing belt 102 in the embodiment of the present application. Fig.19 FIG. 1 shows a process in which the fixing belt 102 is assembled by rotating relative to the device body 101.

In some embodiments, the fixing belt 102 is further provided with a stop block 136, which is located on the fourth side 130, wherein one of the second limiting structures 106 is located between the second electrical connector 105 and the stop block 136, and after the fixing belt 102 is connected to the device body 101, the stop block 136 is located at the accommodating space 118, and the stop block 136 abuts against the side wall of the accommodating space 118, and when the button body 121 returns to its original position, part of the structure of the fixing belt 102 also extends into the mounting groove 116, and this part of the structure of the fixing belt 102 abuts against the button body 121, thereby realizing that the fixing belt 102 cannot move relative to the device body 101, and ensuring a stable connection between the fixing belt 102 and the device body 101. In one embodiment, the length of the stop block 136 in the thickness direction of the fixing belt 102 is smaller than the spacing between the two first limit blocks 113 in the first limit structure 104 in the thickness direction of the device body 101, so that during the assembly process, the stop block 136 can be inserted between the two first limit blocks 113, thereby not interfering with the second limit block 115 entering the first limit groove 114 from the accommodating space 118.

[0140] See also Fig. 22 As shown, Fig. 221 is an exploded view of the fixing belt 102 in the embodiment of the present application. In some embodiments, the fixing belt 102 may include a bracket 139 and a deformable body 138, wherein the deformable body 138 and the bracket 139 may be fixedly connected. The second electrical connector 105 and the second limiting structure 106 may both be located on the bracket 139. The bracket 139 is made of a hard material, and thus can provide a relatively stable support, so as to facilitate the reliability of the electrical connection of the second electrical connector 105, and the structural stability of the second limiting structure 106 engaging with the first limiting structure 104.

[0141] In some embodiments, the second mounting surface 134 is located on the bracket 139, the second limit block 115 is fixedly connected to the bracket 139, and the stop block 136 is fixedly connected to the bracket 139. The bracket 139 and the deformable body 138 can be fixedly connected by bonding or embedding the bracket 139 into the deformable body 138. For example, Fig. 22 As shown, the bracket 139 can be embedded in the deformable body 138. The material of the deformable body 138 can be plastic, leather or metal. It should be noted that in some other possible implementations, the second limiting structure 106 can be set on the deformable body 138.

[0142] In some embodiments, the second electrical connector 105 can be integrally formed with the bracket 139, or fixed to the bracket 139 by bonding, welding, screws, etc. The first electrical connector 103 can be integrally formed with the device body 101, or fixed to the device body 101 by bonding, welding, screws, etc. The waterproof rubber ring 135 can be integrally formed with the device body 101, or fixed to the device body 101 by bonding or welding.

[0143] Combination Fig.23 and Fig.24 As shown, Fig.23 1 is a schematic diagram of a partial structure of another embodiment of the present application when the fixing belt 102 is separated from the device body 101. Fig.24 1 is a partial structural diagram of another embodiment of the present application when the fixing belt 102 is connected to the device body 101, wherein Fig.23 and Fig.24Only a part of the structure of the device body is shown. In some other embodiments, the first mounting surface can be in the form of an arc surface. When the first mounting surface is an arc surface, that is, the first mounting surface is a first docking arc surface, the first electrical connector 103 is located on the first docking arc surface, and a plurality of contact pieces 108 can be arranged along an arc line on the first docking arc surface, and the arc line can be an arc shape. The second mounting surface 134 on the fixing belt 102 can be in the form of an arc surface. When the second mounting surface 134 is an arc surface, that is, the second mounting surface 134 is a second docking arc surface, the second electrical connector 105 is located on the second docking arc surface, and a plurality of pins 109 can be arranged along an arc line on the second docking arc surface, and the arc line can be an arc shape, so that the second electrical connector 105 located on the second docking arc surface can be electrically connected to the first electrical connector 103 located on the first docking arc surface. In the case where the first docking arc surface cooperates with the second docking arc surface, when the fixing belt 102 rotates relative to the device body 101, the distance between the first docking arc surface and the second docking arc surface can remain unchanged, and the waterproof rubber ring 135 will not be locally compressed, thereby avoiding the possibility of failure of the waterproof rubber ring 135, thereby helping to delay the wear of the waterproof rubber ring 135 and increase the service life of the waterproof rubber ring 135. In addition, due to the arc surface docking, it is helpful to avoid squeezing the pin 109 during the installation process. For the pin 109, the length direction of the pin 109 can point to the center of the circle corresponding to the arc. In this case, the length of each pin 109 can be set equally; or the length directions of multiple pins 109 are set parallel to each other. When multiple pins 109 are set parallel to each other, the length of each pin 109 will be different, and the specific length can be set according to actual needs. When both the first mounting surface and the second mounting surface 134 are arc surfaces, more pins 109 and contact pieces 108 can be arranged, or the distance between two adjacent pins 109 or two adjacent contact pieces 108 can be increased, which is conducive to designing the number and distance between the pins 109 and the contact pieces 108. The waterproof rubber ring 135 is also arc-shaped, which is more conducive to waterproofing.

[0144] Combination Fig.25 and Fig.26 As shown, Fig.25 1 is a cross-sectional schematic diagram of another embodiment of the present application when the fixing belt 102 is connected to the device body 101. Fig.26 yes Fig.25Schematic diagram of a cross section when the fixing belt 102 is connected to the device body 101. In other embodiments, the first limiting structure 104 can be located on both sides of the thickness direction of the device body 101, that is, the first electrical connector 103 has an upper side and a lower side relative to each other. For example, the first limiting structure 104 is provided on both sides of the thickness direction of the device body 101. The direction from the upper side to the lower side is parallel to the thickness direction of the device body 101; and the first side 110 or / and the second side 111 are equipped with a trigger key 107; a first limiting groove 114 is formed between the first limiting block 113 of the first limiting structure 104 and the shell of the device body. The second limiting structure 106 can be located on both sides of the thickness direction of the fixing belt 102, that is, the second electrical connector 105 has an upper side and a lower side relative to each other. For example, the second limiting structure 106 is provided on both sides of the thickness direction of the fixing belt 102; the direction from the upper side to the lower side of the fixing belt 102 is parallel to the thickness direction of the fixing belt 102. The second limiting block 115 of the second limiting structure 106, in this case, the fixing belt 102 moves along the first direction F relative to the device body 101, so that the second limiting block 115 of the second limiting structure 106 moves to the first limiting groove 114, and the first limiting structure 104 and the second limiting structure 106 are limited, that is, the two are engaged and connected. After the first limiting structure 104 and the second limiting structure 106 are adjusted to the upper and lower sides of the corresponding electrical connectors, it is helpful to reduce the width of the strap and meet the demand for a narrower width strap.

[0145] It should be noted that, in some other possible embodiments, the direction from the first side 110 to the second side 111 can be parallel to the thickness direction of the device body 101, and the arrangement direction of the multiple contact pieces 108 of the first electrical connector 103 is perpendicular to the thickness direction of the device body 101; the direction from the first side 110 to the second side 111 is parallel to the first direction F, and the first side 110 and the second side 111 can also be respectively provided with a first limiting structure 104. The direction from the third side 129 to the fourth side 130 is parallel to the thickness direction of the fixing belt 102; the arrangement direction of the plurality of pins 109 of the second electrical connector 105 is perpendicular to the thickness direction of the fixing belt 102; the third side 129 and the fourth side 130 can also be provided with a second limiting structure 106 respectively; the first limiting structure 104 located on the first side 110 cooperates with the second limiting structure 106 located on the third side 129, and the first limiting structure 104 located on the second side 111 cooperates with the second limiting structure 106 located on the fourth side 130, so that the fixing belt 102 and the device body 101 can be connected from top to bottom or from bottom to top. Therefore, the connection and disassembly method between the fixing belt 102 and the device body 101 in the embodiment of the present application is not limited to pushing left and right, or rotating left and right, but can also be realized by disassembly from top to bottom, and the up and down direction is the thickness direction of the device body 101.

[0146] See also Fig. 27 As shown, Fig. 27 1 is a schematic diagram of the structure of another key body 121 in the embodiment of the present application. In some other embodiments, the other side opposite to the panel structure 123 is provided with a step structure; the step structure includes a first vertical surface 141 and a first contact surface 142, and the other side opposite to the panel structure 123 and the first contact surface 142 are respectively connected to the first vertical surface 141, and there is a height difference between the first contact surface 142 and the other side opposite to the panel structure 123; the first vertical surface 141 faces the direction where the first electrical connector 103 is located. In this way, the step structure is used to realize a fool-proof design during installation to reduce the excessive movement distance of the fixing belt 102 relative to the device body 101. In one embodiment, when the fixing belt 102 rotates relative to the device body 101, the first limiting structure 104 and the second limiting structure 106 are engaged; and the step structure can limit the rotation angle. The side surface opposite to the panel structure 123 can be called the appearance surface 140. The height difference between the appearance surface 140 and the first contact surface 142 can be designed so that when the position pressed by the fixing belt 102 is the appearance surface 140, a collision occurs between the first limiting structure 104 and the second limiting structure 106; and when the fixing belt 102 presses the first contact surface 142, no collision occurs between the first limiting structure 104 and the second limiting structure 106.

[0147] Specifically, when the fixing belt 102 moves along the first direction F, since the fixing belt 102 overlaps the appearance surface 140, the first contact surface 142 cannot contact the fixing belt 102, so that the first limiting structure 104 and the second limiting structure 106 located on the first side 110 will overlap, causing a collision between the first limiting structure 104 and the second limiting structure 106, that is, the first limiting block 113 collides with the second limiting block 115, and then the second limiting block 115 cannot enter the first limiting groove 114, thereby making it impossible for the fixing belt 102 to be connected to the device body 101. When the position pressed by the fixing belt 102 is the first contact surface 142, when the fixing belt 102 moves along the first direction F, the first limiting structure 104 and the second limiting structure 106 will not collide, that is, the first limiting block 113 and the second limiting block 115 will not collide, and the second limiting block 115 can smoothly enter the first limiting groove 114, so that the fixing belt 102 is connected to the device body 101. Therefore, by setting the step structure, the moving distance of the fixing belt 102 relative to the device body 101 is limited, which plays a fool-proof role.
