The invention provides a smart bracelet.

Referring to Fig. 1, the smart bracelet 10 generally includes a watch band 11 and a dial 12 that are connected to opposite ends of the dial 12 to form a loop for the user to wear. Here, the user can communicate with the mobile phone through the smart bracelet 10, thereby implementing functions such as stepping, recording the walking route, and viewing time for the user. It can also be connected with the air conditioner, so that the user can adjust the temperature, operation mode and the like of the air conditioner through the smart bracelet 10.

In the present embodiment, as shown in FIGS. 2 to 5, the smart bracelet 10 includes a dial 12 having a housing 12a and a controller disposed in the housing 12a, the housing 12a having an arm attached thereto The back plate 121 is provided with a temperature sensor 12b and a capacitor piece 12c, and the temperature sensor 12b and the capacitor piece 12c are electrically connected to the controller.

The dial 12 includes a housing 12a, a controller, a temperature sensor 12b, and a capacitance detecting device. The housing 12a has a backing plate 121 for attaching to the arm, and the temperature sensor is disposed on the backing plate 121. The capacitance detecting device includes a capacitor chip 12c and a first capacitor chip electrically connected to the capacitor chip 12c, the capacitor chip 12c is disposed on the back plate, and the temperature sensor and the first capacitor chip are both connected to the controller Electrical connection.

Specifically, the temperature sensor 12b has an inductive chip 123 (refer to FIG. 8). When the user wears the smart bracelet 10, the user's arm is in contact with the temperature sensor 12b, and the resistance value of the sensing chip 123 itself changes, thereby the user's body temperature signal. It is converted into an electrical signal, which is then presented by the controller to the user in the form of data. The controller is further provided with a capacitance detecting chip. When the user's arm is close to the capacitor piece 12c, the capacitance changes, and the capacitance detecting chip detects the change.

In addition, the smart bracelet 10 can also be used for communication connection with the air conditioner, thereby facilitating the user to adjust the temperature, operation mode and the like of the air conditioner through the smart bracelet 10. Here, the smart bracelet 10 can function as a remote controller. When the smart wristband 10 detects that the user's body temperature is high, the smart bracelet 10 can control the air conditioner to open by itself. When the smart bracelet 10 detects that the user's body temperature is low, the smart bracelet 10 can control the air conditioner to turn off by itself.

Both the temperature sensor 12b and the capacitance detecting device can detect whether the user wears the smart bracelet 10. For example, the human body temperature is generally around 37.5 ° C, the air temperature is generally between 0 and 30 ° C, and the air temperature is lower than the user's body temperature. Through this difference, it is possible to detect whether the user wears the smart bracelet 10 . However, if the user wears the smart bracelet 10 is not strong enough, the temperature sensor 12b is unstable in detecting the temperature of the user's arm. In addition, when the user does not wear the smart bracelet 10, when the user touches the capacitive sheet 12c with a finger, the capacitance may also change; or if there is water close to the capacitive sheet 12c, the capacitance may also change. Therefore, in the present embodiment, by the combination of the temperature sensor 12b and the capacitance detecting device, the controller determines that the user wears the smart bracelet 10 only when the temperature sensor 12b acquires the user's body temperature and the capacitance detecting device detects the capacitance change. In turn, the smart bracelet 10 is prevented from regulating the air conditioner or the mobile phone in a non-wearing condition.

The technical solution of the embodiment provides a temperature sensor 12b and a capacitor chip 12c on the back plate 121 of the smart bracelet 10, and the temperature sensor 12b and the capacitance detecting device jointly detect whether the user wears the smart bracelet 10, thereby greatly improving the smart bracelet. 10 The accuracy of wearing the detection improves the intelligence of the smart bracelet 10.

Referring to FIG. 4, FIG. 5 and FIG. 6, in the above embodiment, the capacitor chip 12c is mounted on the back plate 121, for example, on the outer surface or the inner surface of the back plate 121, or is embedded in the back plate 121. of. Here, considering the ease of assembly of the capacitor chip 12c and the production cost of the entire smart bracelet 10, in the present embodiment, the capacitor chip 12c is mounted on the inner surface of the back plate 121. Thus, the assembly of the capacitor piece 12c by the worker is extremely convenient and quick.

Referring to FIG. 5 and FIG. 6, although the capacitor chip 12c is mounted on the inner surface of the back plate 121, it is convenient and quick, but if the capacitor piece 12c is not fixed, its stability is poor, and it is easy to deviate from the original position, which may affect the capacitance detection. The detection effect of the device. In this embodiment, the inner surface of the back plate 121 is provided with a protrusion 121a, and the capacitor plate 12c is provided with a positioning hole 120c corresponding to the position of the protrusion 121a, and the capacitor piece 12c passes the positioning. The hole 120c is sleeved with the protrusion 121a and fixed to the back plate 121. Thus, the capacitor chip 12c does not shift on the back plate 121, and the stability is good.

Referring to FIG. 7, in another preferred embodiment, similarly, in order to improve the stability of mounting of the capacitor chip 12c on the back plate 121, the capacitor piece 12c is provided with a support rod 121c, and the capacitor piece 12c passes through The support rod 121c is coupled to the controller. Here, the support rod 121c is used to support the capacitor piece 12c to prevent the external force from pressing the back plate 121 to cause the capacitor piece 12c to be detached from the back plate 121. The support rod 121c may be a metal rod. The capacitor piece 12c is electrically connected to the controller through the support rod 121c. The support rod 121c may also be a plastic rod. The capacitor piece 12c is connected to the controller through a wire, and the wire passes through the plastic rod.

Referring to FIG. 4, although the capacitor chip 12c can be mounted on the outer surface, the inner surface of the back plate 121, or embedded in the back plate 121, the distance between the capacitor chip 12c and the outer surface of the back plate 121 is not too large, otherwise the capacitance detecting device may be caused. The sensitivity is poor. Therefore, in order to improve the sensitivity of the capacitance detecting device, the distance between the capacitive sheet 12c and the outer surface of the backing plate 121 is between 0 m and 2 mm.

Referring to FIG. 5 and FIG. 6, in a preferred embodiment, in order to improve the wearing comfort of the user and the firmness of the installation of the temperature sensor 12b, the back plate 121 is provided with a mounting hole 120, and the temperature sensor 12b includes a The heat conducting portion 122 is mounted on the mounting hole 120 by the sensing chip 123 and the heat conducting portion 122 connected to the sensing chip 123. Here, the sensing chip 123 of the temperature sensor 12b is connected to the controller (circuit board) through a wire, and the heat conducting portion 122 covers the sensing chip 123. When the user's arm contacts the heat conducting portion 122, the heat conducting portion 122 conducts the body temperature to the sensing portion. The chip 123 changes the resistance value of the sensing chip 123 itself, thereby converting the user's body temperature signal into an electrical signal, and then the controller presents the electrical signal to the user in the form of data.

On the basis of the previous embodiment, referring to FIG. 2 to FIG. 6 , in order to improve the stability of the heat conducting portion 122 mounted on the back plate 121 , in the present embodiment, the heat conducting portion 122 is embedded in the outer casing 12 a . The heat conducting portion 122 is generally a metal member having a high melting point and can be first produced by injection molding of a mold, and of course, can also be formed by lathe processing. The outer casing 12a is made of plastic and has a low melting point. After the heat transfer portion 122 is produced, the heat transfer portion 122 is placed in a mold together with the material from which the outer casing 12a is formed, and is injection molded. In the injection molding process, since the melting point of the material of the outer casing 12a is low, when the injection temperature reaches the melting point of the material of the outer casing 12a, the material of the outer casing 12a melts, and the heat conducting portion 122 does not melt, so that the heat conducting portion 122 can be embedded in the outer casing after being cooled. In 12a, the stability of the connection between the two is greatly enhanced.

Referring to FIG. 4, FIG. 5 and FIG. 6, in general, the sensing chip 123 of the temperature sensor 12b is fixed on a thermally conductive spacer 124, and the heat conducting portion 122 covers the sensing chip 123 while being fixed. On the spacer 124. The sensing chip 123 is sensitive to the temperature. In order to prevent the sensing chip 123 from being interfered by the unconnected factor, and in order to provide protection to the sensing chip 123, in the embodiment, the heat conducting portion 122 has an inner surface and an outer surface. The inner surface of the heat conducting portion 122 is partially recessed toward the outer surface to form a recess for receiving the sensing chip. When the heat conducting portion 122 is mounted on the spacer 124, the sensing chip is placed in the recess, and the sensing chip abuts against the groove bottom of the recess.

Referring to FIG. 6, if the contact area of the heat conducting portion 122 with the spacer 124 is small, the connection effect of the heat conducting portion 122 with the spacer 124 is poor. In a preferred embodiment, the heat conducting portion 122 includes a substrate 122a, and the substrate 122a is attached to the spacer 124, and the recess is disposed on the substrate 124. On the substrate 122a. In this way, the substrate 122a is attached to the spacer 124, and the contact area is large, and the mounting is relatively firm.

In addition, the inner surface of the heat conducting portion 122 is partially recessed toward the outer surface to form a boss 122b on the outer surface, the groove being located in the boss 122b. In this way, the heat conducting portion is arranged on the ladder and the mounting is firmer.

With continued reference to FIGS. 5 and 6, in order to cooperate with the mounting of the heat conducting portion 122, the mounting hole 120 includes a recess 120a formed by the inner surface of the back plate 121, and a groove bottom provided at the groove 120a. The first through hole 120b, the substrate 122a is received in the groove 120a, and the boss 122b is inserted into the first through hole 120b. On the one hand, under the double limit of the groove 120a and the first through hole 120b, the stability of the heat conducting portion 122 is better; on the other hand, the inner space of the dial 12 is small, and is received by the groove 120a, which is greatly reduced. The probability of interference of the thermally conductive portion 122 with other structures within the housing may also provide more space for the placement of other electronic components.

In addition, referring to FIG. 4, it should be noted that the heat conducting portion 122 needs to be in direct contact with the user's arm, so the boss 122b must protrude from the outer surface of the bottom of the outer casing or be flush with the outer surface of the bottom of the outer casing. Of course, here, the end surface of the boss 122b is flush with the outer surface of the back plate 121 as a preferred embodiment. In this way, the boss 122b is prevented from being pressed against the user's arm, and the user is more comfortable to wear. In addition, the end surface of the boss 122b is flush with the outer surface of the back plate 121 to avoid the interference probability of the boss 122b and the outside, thereby The sensor 12b has a protective effect.

In this embodiment, as shown in FIG. 2 and FIG. 10, a display screen 12f is disposed in the outer casing 12a, and the dial 12 further includes a touch capacitance sensing device, and the touch capacitance sensing device includes a touch for the user. a sensing capacitor portion, and a second capacitor chip electrically connected to the sensing capacitor portion, the second capacitor chip is electrically connected to the controller, and the display screen 12f is electrically connected to the controller when the user The controller controls the display screen 12f to switch the display content when the sensing capacitance portion is touched.

Specifically, the outer casing 12a has an upper cover 125, a back plate 121, and a side plate (not shown) between the upper cover 125 and the back plate 121. In order to facilitate the user to view the display screen 12f, the upper cover 125 or the side plate is usually provided. It is set transparently. Display screen 12f presents information to the user via a transparent upper cover 125 or a transparent side panel.

When the smart bracelet 10 is connected to the mobile phone, the display screen 12f can display missed calls, short messages, etc., and can also display the number of steps the user walks, the walking route, and the like. When the smart bracelet 10 is communicatively connected to the air conditioner, the display screen 12f can display the outside temperature, humidity, mode of operation of the air conditioner, and the like. Here, taking the air conditioner as an example, since the size of the smart bracelet 10 is small, the area of the display screen 12f is also small, and various information such as temperature, humidity, wind power, and operation mode are difficult to display on the same interface. In this embodiment, the user can switch the display interface to the display screen 12f by touching the sensing capacitance portion, thereby presenting different information to the user through different display interfaces.

The sensing capacitor portion includes a capacitive sensing sheet 12d. Of course, the sensing capacitor portion may further include a sensing region located in the housing 12a, and the capacitive sensing sheet 12d is positively sensed by the sensing region. The test piece 12d is electrically connected to the second capacitor chip. When the user touches the sensing capacitance portion, the user himself acts as a conductor, a capacitance is formed between the user's finger (for example, a finger) and the capacitance sensing sheet 12d, and when the user's finger gradually approaches the capacitance sensing sheet 12d, the touch capacitance is sensed. The capacitance detected by the measuring device gradually becomes larger (C=εS/4πkd), and when the capacitance detected by the touch capacitance sensing device exceeds a preset value, the controller controls the display screen 12f to switch the display content. It should be noted that the capacitive sensing piece 12d may be disposed on the inner surface of the outer casing 12a or may be disposed on the outer surface of the outer casing 12a (that is, the capacitive sensing piece 12d leaks from the outer surface of the outer casing for direct touch by the user).

Here, the capacitive sensing piece 12d may generally face the upper cover 125 and be disposed adjacent to the upper cover 125; or may face the side plate and be disposed adjacent to the side plate. In this way, the user can conveniently touch the sensing capacitance portion to realize switching of the display content. Of course, the capacitive sensing piece 12d can also face the back plate 121 and be disposed adjacent to the side plate. For example, the back plate 121 has an inner surface and an outer surface. The outer surface of the back plate 121 is recessed toward the inner surface and forms a boss on the inner surface. The capacitive sensing piece 12d can be mounted on the boss so that when the user wears, the capacitor The distance between the sensing piece 12d and the user's arm is far, the second capacitor chip is difficult to detect the capacitance, or the detected capacitance does not exceed the preset value, and the controller does not control the display screen 12f to switch the display interface. When the user extends the finger from the outer surface of the outer casing 12a into the boss, the distance between the capacitive sensing piece 12d and the finger is small, and the capacitance detected by the touch capacitance sensing device exceeds a preset value, and the controller controls The display screen 12f switches the display interface. In addition, the capacitive sensing piece 12d can be directly mounted on the inner surface of the back plate 121. Generally, when the smart bracelet 10 is worn by the user, the smart bracelet 10 is not over-tightened, otherwise the user is uncomfortable to wear, so There is usually a partial gap between the back plate 121 and the arm, and due to the presence of the gap, it is difficult for the arm to trigger the controller to switch the display interface. When the user applies pressure to the whole of the dial 12, and the back plate 121 is in close contact with the arm (the back plate 121 is tightly attached to the arm, or the back plate 121 is compressed and thinned), between the capacitive sensing piece 12d and the arm The distance is reduced), the second capacitor chip can detect that the capacitance exceeds a preset value, so that the controller controls the display screen 12f to switch the display interface.

The technical solution of the present embodiment provides a touch capacitance sensing device in the outer casing 12a of the smart bracelet 10, so that the user can switch the display content of the display screen 12f by touching the sensing capacitance portion, thereby improving the smart bracelet. 10 practicality.

It is considered that during the actual operation, the capacitance sensing piece 12d may be displaced due to an external force, thereby affecting the accuracy of the detection by the touch capacitance sensing device. Therefore, in a preferred embodiment, in order to make the mounting of the capacitive sensing piece 12d more secure, the inner surface of the upper cover 125 is recessed to form a receiving groove, and the capacitive sensing piece 12d is limited to the receiving portion. groove.

Referring to FIG. 9, in order to facilitate the user to intuitively switch the display interface, in a preferred embodiment, the housing 12a has a see-through panel for the display screen 12f, and the capacitive sensing sheet 12d faces the perspective. The board is placed close to the see-through panel. Here, the see-through panel is a transparent plate or a translucent plate, and the see-through plate may be an upper cover 125 or a side plate, which is not limited herein.

In the above embodiment, the see-through panel may be the upper cover 125 or the side panel. Generally, in order to facilitate the user to view the display screen 12f, the display screen 12f is preferably disposed toward the upper cover 125. Thus, the user can intuitively view the display screen 12f. Therefore, in the present embodiment, the see-through panel is preferably an upper cover 125.

Referring to FIGS. 9-11, the dial 12 of the smart wristband 10 is generally substantially elongated or oblate, and the display screen 12f is also generally rectangular. The display screen 12f is disposed near the middle of the upper cover 125. The test piece 12d may be disposed around the display screen 12f, but since the display screen 12f is spaced apart from the frame of the upper cover 125 in the width direction thereof, the capacitance sensing piece 12d is disposed on the one hand in the width direction of the display screen 12f. Not conducive to installation, on the other hand is not conducive to user operations. Therefore, here, in order to facilitate the user's operation, the upper cover 125 has opposite ends in the longitudinal direction thereof, and the capacitive sensing piece 12d is disposed near the inner surface of one end thereof. Thus, the capacitive sensing piece 12d does not block the display screen 12f.

In another preferred embodiment, referring to FIG. 9 and FIG. 11, in order to further enhance the stability of the mounting of the capacitive sensing piece 12d, the outer periphery of the display screen 12f is sleeved with a supporting portion 12h, and the supporting portion 12h is pressed. The capacitive sensing sheet 12d is to the see-through panel. Here, the supporting portion 12h has a protective effect on the display screen 12f, and on the other hand, the capacitive sensing piece 12d can be restrained between the upper cover 125 and the supporting portion 12h, and the position of the capacitive sensing piece 12d It is not easy to change, which ensures the accuracy of the detection of the touch capacitance sensing device.

Referring to FIG. 10, the capacitive sensing piece 12d is often subjected to an external force in the outer casing 12a. For example, the smart wristband 10 is dropped, subjected to a collision, etc., which may cause the position of the capacitive sensing piece 12d to shift, which constantly affects the sensing of the touch capacitance. The accuracy of the device detection may also cause the capacitive sensing piece 12d to be out of the original position. Herein, in order to further improve the stability of the mounting of the capacitive sensing piece 12d in the outer casing 12a, a circuit board 12g is further disposed in the outer casing 12a, and the touch capacitance sensing device further includes the capacitive sensing piece 12d. The clamping portion 127 is disposed side by side, and the clamping portion 127 is connected to the capacitive sensing piece 12d via a connecting portion 126, and is formed with a clip between the capacitive sensing piece 12d and the clamping portion 127. a slot that holds the support portion 12h and the circuit board 12g. Under the clamping action of the clamping groove, the capacitive sensing piece 12d is firmly adhered to the supporting portion 12h, the clamping portion 127 is firmly adhered to the circuit board 12g, and the connecting portion 126 is subjected to the abutting limit of the side plate. The stability of the mounting of the capacitive sensing piece 12d is greatly improved.

Referring to FIG. 9, the distance between the capacitor plate and the outer surface of the outer casing 12a is not too large, which may result in poor sensitivity of the touch capacitance sensing device. Therefore, in order to improve the sensitivity of the touch capacitance sensing device, the distance between the capacitance sensing piece 12d and the outer surface of the outer casing 12a is between 0 m and 2 mm.

In another preferred embodiment, as shown in FIG. 12 and FIG. 13, the dial 12 includes a housing 12a having a cavity, and a circuit board 12g, a battery 12i, and a display 12k disposed in the cavity. The circuit board 12g divides the cavity into a first chamber 1210 and a second chamber 1220, and the display screen 12k and the battery 12i are correspondingly disposed in the first chamber 1210 and the second chamber The chambers 1220 are electrically connected to the circuit board 12g.

Specifically, the outer casing 12a of the dial 12 has a bottom case 121' and an upper cover 125, and the upper cover 125 covers the bottom case 121' and defines the cavity together with the bottom case 121'. The circuit board 12g is mounted in the cavity, and the circuit board 12g divides the cavity into two. The circuit board 12g itself has two sides, and when the user wears the smart bracelet 10, the reverse side faces the user's arm, and the front side faces the upper cover 125. The circuit board 12g can be mounted in the cavity in a manner that the circuit board 12g abuts against the inner wall of the cavity and is held between the opposite inner walls; or a mounting groove is formed in the inner wall of the cavity, and the circuit board 12g is inserted into the circuit board 12g. In the mounting groove, it is also possible to fix the circuit board 12g in the cavity through the limiting structure. Since the display screen 12k is for displaying information of the smart bracelet 10 to the user, the display screen 12k is disposed in the first chamber 1210 and displayed to the user through the transparent or translucent upper cover 125. In addition, the display screen 12k is generally plate-shaped. After the display screen 12k is disposed in the first chamber 1210, the remaining space is small in thickness, which is inconvenient to set a large-sized circuit component, but a volume can be set in the space. Small circuit components to make the most of space. The volume of the battery 12i is relatively large (relative to some electrical components such as resistors, diodes, etc. on the circuit board 12g), and the circuit components of the reverse side of the circuit board 12g are generally less (generally no electronic components are provided), and the battery is After the 12i is disposed in the second chamber 1220, the battery 12i occupies most of the space of the second chamber 1220, so that the space of the second chamber 1220 can be fully utilized.

The technical solution of the embodiment divides the cavity of the outer casing 12a into two chambers by the circuit board 12g, and the display screen 12k and the battery 12i are respectively disposed in the two chambers, thereby fully utilizing the space in the outer casing 12a, thereby improving The internal space utilization of the smart bracelet 10 reduces the volume of the smart bracelet 10.

On the basis of the previous embodiment, referring to FIG. 15, the bottom case 121' has an opening and a back plate 121 opposite to the opening, and the back plate 121 is provided with a support portion 1211, and the support portion 1211 supports the The circuit board 12g forms the second chamber 1220 between the circuit board 12g and the back plate 121. Here, the support portion 1211 has a support function for the circuit board 12g in addition to the circuit board 12g and the back plate 121 forming the second chamber 1220, thereby preventing the circuit board 12g from collapsing.

In the previous embodiment, the support portion 1211 only supports the circuit board 12g. After the circuit board 12g is installed in the cavity, it is not stable enough, and the circuit board 12g may be shaken, thereby causing the first chamber 1210 and the second. The stability of the circuit components within the chamber 1220 is poor. In the present embodiment, referring to FIG. 13 and FIG. 15, the support portion 1211 is fixedly connected to the circuit board 12g. For example, the circuit board 12g and the support portion 1211 are connected by a screw. For example, a fixing hole is formed in the circuit board 12g, and a protruding cap is disposed on the supporting portion 1211. The protruding cap is inserted into the fixing hole of the circuit board 12g, and the protruding cap is interference-fitted with the fixing hole. In this way, the circuit board 12g can be effectively prevented from shifting between the first chamber 1210 and the second chamber 1220 to affect the stability of the circuit component; on the other hand, the degree of collision between the circuit board 12g and the inner wall of the cavity can be slowed down. It is possible to avoid the occurrence of breakage of the joint of the circuit component and the circuit board 12g due to the vibration of the circuit board 12g.

In a preferred embodiment, referring to Figures 15 through 17, in order to further reduce the volume of the smart bracelet 10, the battery 12i is disposed in a plate shape. Here, since the circuit board 12g and the display screen 12k are both disposed in a plate shape, the space occupancy ratio of the two in the cavity is small, and the battery 12i is arranged in a plate shape, on the one hand, the battery 12i and the circuit board 12g are facilitated. In conjunction with the installation, on the other hand, the space occupancy of the entire smart bracelet 10 is reduced, making the dial 12 of the smart bracelet 10 thinner.

In another preferred embodiment, referring to FIG. 15, the smart bracelet 10 is further provided with a vibrator 12j. When the user is inconvenient to view the display screen 12k, the smart bracelet 10 can transmit information to the user through the vibrator 12j. For example, when the user's mobile phone has a text message arriving, the vibrator 12j can vibrate to prompt the user to avoid the user missing the short message. Here, the vibrator 12j is mounted to the circuit board 12g, and the vibrator 12j is located in the second chamber 1220.

The smart bracelet 10 consumes less power. Generally, the volume of the battery 12i does not have to be too large. Compared with the reverse side of the circuit board 12g, the projected area (vertical projection) of the battery 12i on the reverse side is smaller than the area of the reverse surface, and the vibrator 12j It is installed outside the projection area of the battery 12i on the reverse side, which can increase the utilization of space.

In addition, since the display screen 12k is disposed in the first chamber 1210, the vibrator 12j is disposed in the second chamber 1220, so that the vibrator 12j can be prevented from contacting the display screen 12k, thereby reducing the occurrence of the screen of the display screen 12k. . Moreover, when the vibrator 12j vibrates, the circuit board 12g also vibrates, which also causes the display screen 12k to vibrate. The closer the vibrator 12j is to the display screen 12k, the greater the vibration amplitude of the display screen 12k, and the vibration amplitude of the display screen 12k is biased. Large also causes the electrical connection between the display screen 12k and the circuit board 12g to break. Therefore, the vibrator 12j is disposed in the second chamber 1220, in addition to improving the utilization of the space, the vibration amplitude of the display screen 12k can be reduced, and the display screen 12k can be prevented from being powered off.

On the basis of the previous embodiment, referring to FIG. 2 and FIG. 15, the circuit board 12g is further provided with a USB plug connector 12m. The USB plug connector 12m can be used for charging the battery 12i, and can also output data or pass through the smart wristband 10. The USB plug connector 12m inputs data to the smart bracelet 10. In the present embodiment, the USB plug connector 12m is mounted to the circuit board 12g, and the USB plug connector 12m is located in the second chamber 1220. Here, the USB plug connector 12m is also mounted outside the projection area of the battery 12i on the reverse side, so that the utilization of the internal space of the smart bracelet 10 can be increased.

In the above embodiment, referring to FIG. 15, The USB plug connector 12m and the vibrator 12j may be mounted at any position on the reverse side of the circuit board 12g, for example, the battery 12i is disposed between the USB plug connector 12m and the vibrator 12j; for example, the USB plug connector 12m and the vibrator 12j are disposed in the battery Adjacent sides of 12i. When the USB plug connector 12m and the vibrator 12j are installed, each space needs to occupy a certain space, and the space is often larger than the minimum space required by the USB plug connector 12m and the vibrator 12j, otherwise it is disadvantageous to the USB plug connector 12m and the vibrator. 12j installation. In this embodiment, the USB plug connector 12m and the vibrator 12j are located on the same side of the battery 12i. Thus, the scattered space required for each of the USB plug connector 12m and the vibrator 12j is integrated, and the space required for the two is smaller. It also reduces the space occupancy of both.

In another preferred embodiment, referring to FIG. 15, the battery 12i has a bottom surface away from the circuit board 12g, and the bottom surface is provided with a temperature sensor 12b electrically connected to the circuit board 12g, the housing having A first through hole 120b, the temperature sensor 12b is mounted to the first through hole 120b. The smart bracelet 10 can also be used for communication connection with the air conditioner, thereby facilitating the user to adjust the temperature, operation mode and the like of the air conditioner through the smart bracelet 10. Here, the smart bracelet 10 can function as a remote controller. When the smart wristband 10 detects that the user's body temperature is high by the temperature sensor 12b, the smart bracelet 10 can control the air conditioner to open by itself. When the smart bracelet 10 detects that the user's body temperature is low, the smart bracelet 10 can control the air conditioner to turn off by itself. In addition, since the human body temperature is generally around 37.5 ° C, the air temperature is generally between 0 and 30 ° C, and the air temperature is lower than the user's body temperature. Through this difference, it is possible to detect whether the user wears the smart bracelet 10, thereby preventing the smart bracelet 10 from being Adjust the air conditioner in a non-wearing condition. In the present embodiment, the temperature sensor 12b is disposed on the bottom surface of the battery 12i, and the temperature sensor 12b needs to leak from the outer casing 12a. Therefore, the temperature sensor 12b hardly occupies the internal space of the outer casing 12a.

In the above embodiment, referring to FIG. 15, it is considered that the structure inside the dial 12 is relatively compact and the space is small, and the wires connecting the circuit board 12g and the temperature sensor 12b cannot be messy, otherwise the assembly of other circuit components is affected. In the embodiment, the temperature sensor 12b is connected to the circuit board 12g through a row of wires 12L. Here, the cable 12L has good ductility, is easy to shape, is not easy to be messy, and has less space occupation. In addition, in order to prevent the end of the connecting wire 12L from being disconnected due to the pulling of the wire 12L during the assembly process, or the end of the connecting temperature sensor 12b of the wire 12L is detached, the wire 12L is "U" shaped. Setting

In another preferred embodiment, as shown in FIG. 1 and FIG. 18 to FIG. 20, the smart bracelet 10 has a dial 12 including a housing 12a and a button 12n having an inner cavity 126. The inner cavity 126 is provided with a switch. The surface of the outer casing 12a defines a second through hole 121I communicating with the inner cavity 126. The button 12n includes a second through hole 121I and is pressed for pressing. The abutting rod 121n of the switch, the abutting rod 121n is sleeved with a sealing ring 127a, and the abutting rod 121n is sealingly abutted against the inner wall of the second through hole 121I through the sealing ring 127a. (Refer to Fig. 23 and Fig. 24).

Specifically, the second through hole 121I can be opened at any position of the dial 12, for example, the upper surface, the lower surface or the side surface of the dial 12 is possible (the lower surface of the dial 12 is in contact with the arm). In order to facilitate the user's operation and also to make the design of the smart bracelet 10 more beautiful, the button 12n is generally disposed on the side of the dial 12.

The button 12n is mounted on the second through hole 121I. The shape of the second through hole 121I is not limited, and the shape thereof may be circular, elliptical or square. Correspondingly, the abutting rod 121n may be in the shape of a cylinder, an elliptical cylinder or a square cylinder. In order to improve the sealing property between the button 12n and the hole wall of the second through hole 121I, the sealing ring 127a is preferably made of a flexible member, and the material thereof may be silica gel, latex or rubber. In addition, the outer diameter of the sealing ring 127a is larger than the outer diameter of the second through hole 121I, so that the sealing ring 127a and the second through hole 121I are in an interference fit.

The sealing ring 127a is sleeved by the abutting rod 121n. The sealing ring 127a may be fixed in the second through hole 121I. For example, the sealing ring 127a is adhered to the inner wall of the second through hole 121I or the inner wall of the second through hole 121I. An annular groove is provided in which the seal ring 127a is mounted. When the abutment rod 121n is pressed, the abutment rod 121n and the seal ring 127a move relatively, and under the sealing action of the seal ring 127a, it is difficult for moisture to enter the inner chamber 126 from between the abutment rod 121n and the seal ring 127a. The seal ring 127a may also be fixed to the abutment rod 121n. For example, the seal ring 127a is bonded to the side wall of the abutment rod 121n, or an annular groove is provided in the side wall of the abutment rod 121n, and the seal ring 127a is installed in the annular groove. When the user presses the abutment rod 121n, the abutment rod 121n moves simultaneously with the seal ring 127a, and under the sealing action of the seal ring 127a, it is difficult for moisture to enter the inner chamber 126 from between the inner wall of the second through hole 121I and the seal ring 127a. Thereby the waterproof performance of the dial 12 is improved. Of course, the sealing ring 127a may also be freely movable. When the user presses the button 12n, the sealing ring 127a may remain stationary, may move together with the abutting rod 121n, or may move relative to the abutting rod 121n.

The technical solution of the embodiment can effectively improve the waterproof performance of the smart bracelet 10 by providing a sealing ring 127a between the abutting pole 121n of the button 12n and the second through hole 121I of the mounting button 12n, thereby improving the smart bracelet. 10 lifetime.

Referring to Figures 20 and 21, the smart bracelet 10 itself is small in size, and the dial 12 is generally 3 cmm - 4 cm in length and 1 cm in width. The switch inside the dial 12 is also small, and the diameter of the abutment rod 121n is small in order to cooperate with the switch. For the user, since the diameter of the abutting rod 121n is small, it is not convenient for the user to directly press the abutting rod 121n with a finger. Further, since the diameter of the abutting rod 121n is small, the user pressing the abutting rod 121n is not comfortable enough (the pressure of the abutting rod 121n on the finger is large). In view of the above, in the embodiment, the button 12n further includes a pressing portion 122n, and the pressing portion 122n is connected to the outer end of the abutting rod 121n, and the outer end of the second through hole 121I is circumferentially The outer cover is arranged in a stepped manner to form a receiving groove 122I for receiving the pressing portion 122n. The pressing portion 122n is flat, and is mainly used to increase the contact area between the button 12n and the user's finger, and is convenient for the user to press.

In the above embodiment, when the user presses the button 12n with a finger, the button 12n needs to be returned to facilitate the next pressing. There are various implementations for implementing the homing of the button 12n. For example, a spring is disposed at the switch. When the user presses the button 12n, the abutting bar 121n abuts the spring and turns the switch on. When the user releases the button 12n, the user Under the action of the shrapnel, the button 12n can be returned. In addition, the button 12n can be manually pulled back by the user to return the button 12n. In the above two embodiments, the former elastic piece is not stable enough (the elastic piece is irreversibly deformed), and once the elastic piece is damaged, the replacement is difficult; the latter is not conducive to user operation, which is time consuming and laborious. In the present embodiment, with reference to FIG. 19, a reset member 127b for homing the button 12n is disposed in the accommodating groove 122I. The reset member 127b may be a rubber pad having elasticity, a spring, a spring piece, or the like. Thus, the reset member 127b can reset the button 12n freely, and the replacement of the reset member 127b is easier and less expensive.

The mounting of the resetting member 127b lacks a limiting structure, and the resetting member 127b is easily displaced in the receiving groove 122I, which may affect the balance of the pressing portion 122n (for example, the resetting member 127b is displaced to the edge position of the pressing portion 122n when the user pairs When the pressing portion 122n is pressed, the abutting rod 121n may deviate from the axial center of the second through hole 121I, thereby causing an increase in the pressing resistance). In a preferred embodiment, referring to FIG. 22, in order to improve the stability of the mounting of the resetting member 127b, the receiving groove 122I has an opening and a groove bottom opposite to the opening, and the groove bottom is opened. The blind hole 127d is a return spring mounted in the blind hole 127d. When the user presses the pressing portion 122n, the return spring is elastically deformed, and the abutting rod 121n extends into the inner cavity 126 to abut the switch. When the user releases the pressing force on the pressing portion 122n, the return spring returns to the deformation, and the button 12n is reset.

In the previous embodiment, the groove bottom of the receiving groove 122I is simultaneously provided with the second through hole 121I and the blind hole 127d. Since the outer casing 12a of the dial 12 is small in volume, its mechanical strength is poor. When the user repeatedly presses the button 12n, the sealing ring 127a presses the wall of the second through hole 121I for a long time, and the second through hole 121I is deformed, thereby pressing the bottom portion of the groove around the second through hole 121I. The blind hole 127d is deformed to affect the reset of the button 12n. In this embodiment, with reference to FIG. 22, the groove bottom of the accommodating groove 122I is provided with a groove 127e between the blind hole 127d and the second through hole 121I. After the groove 127e is disposed, even if the sealing ring 127a presses the hole wall of the second through hole 121I, the second through hole 121I is deformed, and the groove 127e gives a predetermined degree to the deformation of the second through hole 121I. The blind hole 127d has a protective effect so as not to affect the reset performance of the button 12n.

In another preferred embodiment, referring to FIG. 21, in order to further improve the reset performance of the reset member 127b, the surface of the pressing portion 122n facing the groove bottom is provided with a positioning post 127f corresponding to the position of the return spring, The positioning post 127f is inserted into the return spring. On one hand, the positioning post 127f has a positioning effect on the return spring, so that the return spring is not easily offset from the original position; on the other hand, the positioning post 127f has a guiding effect on the return spring, so that the return spring is elastically deformed.

In a preferred embodiment, referring to FIG. 21, in order to enhance the fastening of the sealing ring 127a, the side of the abutting rod 121n is provided with a first annular groove 129a, and the sealing ring 127a is at the limit An annular groove 129a. Here, if the seal ring 127a is relatively movable with respect to the hole wall of the second through hole 121I and the abutment rod 121n, the final seal ring 127a may enter the inner cavity 126 from the inner port of the second through hole 121I. It may also come out of the outer port of the second through hole 121I, thereby causing the button 12n to fail, affecting the performance of the smart bracelet 10. After the first annular groove 129a is disposed, the first annular groove 129a has a limiting action on the sealing ring 127a. When the user presses the button 12n, the sealing ring 127a moves back and forth along with the abutting rod 121n, and the sealing ring 127a does not The abutment rod 121n falls off.

Referring to FIG. 19, in order to prevent the button 12n from falling off from the second through hole 121I, in an embodiment, the abutting rod 121n extends into the side of the inner cavity 126 to provide a position for the abutting rod 121n. The circlip of the second through hole 121I is described. After the circlip 127c is provided, the circlip 127c can abut against the inner wall of the outer casing 12a, and the button 12n is difficult to escape from the second through hole 121I. In addition, in order to facilitate the installation of the circlip 127c, a second annular groove 129b may be disposed on the side of the limiting rod 121n, and the retaining limit of the circlip spring 127c is located in the second annular groove 129b.

In the present embodiment, as shown in FIG. 1, FIG. 14, and FIG. 25, the dial 12 of the smart bracelet 10 has a casing including a bottom case 12a and an upper cover 125, and the upper cover 125 and the bottom case 12a is sealed by adhesive, and the adhesive is not visible in the figure. The position of the adhesive is not limited as long as it can be bonded to the upper cover and the two are sealed.

Specifically, in life, due to some of the user's living habits, it is inevitable to contact with water frequently. The smart bracelet 10 is similar to a wristwatch, and the user often comes into contact with water during the wearing process, which may cause the smart bracelet 10 to work abnormally. In addition, in humid weather, moisture in the air may also enter the interior of the smart bracelet 10.

The moisture often enters the inside of the dial 12 from the gap between the bottom case 12a and the upper cover 125. In order to prevent moisture from entering the inside of the dial 12, in the embodiment, the upper cover 125 and the bottom case 12a are sealed by adhesive sealing. Here, the bottom case 12a and the upper cover 125 can be integrally formed by an injection molding process, and the formed bottom case 12a has an inner cavity 128 and an opening 121b, and the circuit board, the vibrator, the display screen, etc. are loaded into the bottom case. After 12a, the adhesive is applied to the periphery of the upper cover 125 or the periphery of the opening 121b, and then the opening 121b is covered by the upper cover 125. After the adhesive is fixed, the bottom case 12a and the upper cover 125 can be sealingly connected.

The technical solution of the embodiment can effectively improve the waterproof performance of the smart bracelet 10 by connecting the upper cover 125 and the bottom case 12a through the adhesive seal, thereby improving the service life of the smart bracelet 10.

Referring to FIG. 14, when the user wears the smart bracelet 10, the upper cover 125 or the bottom case 12a of the smart bracelet 10 often collides with the outside, which may cause the glue to crack. For example, the upper cover 125 and the bottom case 12a are misaligned due to an external force. In view of the above, in the present embodiment, the bottom case 12a has upper and lower surfaces. When the user wears, the bottom wall of the dial 12 is attached to the arm, and the top wall provides a display interface to the user, at the top of the bottom case 12a. The wall partially has an opening 121b communicating with the inner cavity 128, and the upper cover 125 is mounted to the opening 121b. Here, the shape of the upper cover 125 is not limited, and for example, a plate-like arrangement (straight plate or arc plate), other regular or irregular shapes are possible. Of course, the outer surface of the upper cover 125 and the top wall of the bottom case 12a are preferably smoothly engaged, on the one hand, and on the other hand, the interference between the upper cover 125 and the outside can be slowed down. Since the opening 121b is partially opened by the top wall, the bottom case 12a and the upper cover 125 are difficult to be simultaneously collided by the outside, and the opening 121b is not restricted between the upper cover 125 and the bottom case 12a. Misplaced. Thereby, the cracking of the adhesive between the upper cover 125 and the bottom case 12a is avoided.

With reference to FIG. 14, on the basis of the previous embodiment, on the one hand, in order to improve the degree of pressure resistance of the upper cover 125, and on the other hand, in order to reduce the collision probability of the upper cover 125 and the outside, in the embodiment, the upper portion The cover 125 is disposed in an outwardly convex curved plate shape, and a peripheral edge of the upper cover 125 abuts against a peripheral edge of the opening 121b. Thus, on the one hand, the upper cover 125 is relatively small in size, and the upper cover 125 disposed in a plate shape is not interfered by the periphery of the dial 12, and the upper cover 125 is more securely mounted at the opening 121b; The upper cover 125 is disposed in an outwardly convex plate shape, thus reinforcing the strength of the upper cover 125 itself, thereby preventing the upper cover 125 from being damaged by the downward pressure.

In another preferred embodiment, referring to FIG. 14, the opening 121b is tapered from the inside to the outside. In this way, on the one hand, the installation of the upper cover 125 is facilitated (the guiding of the upper cover 125 has a certain guiding effect), on the other hand, the portion of the bottom case 12a corresponding to the periphery of the opening 121b is inclined, and the bottom case 12a supports the upper cover 125. Therefore, even if the upper cover 125 is subjected to downward pressure, it is not easily collapsed, and thus has a protective effect on the dial 12.

Referring to FIG. 3, FIG. 14, and FIG. 26, although the adhesive can well protect the tightness between the bottom case 12a and the upper cover 125, the adhesive may be partially separated as the smart wristband 10 is used for a long time. The bottom case 12a, which in turn causes a decrease in sealing property. In this embodiment, in order to further improve the sealing between the upper cover 125 and the bottom case 12a, the inner surface ring of the upper cover 125 is provided with a convex ring 124e extending into the inner cavity 128, the inner cavity The side wall of the 128 is provided with a recess 121d for receiving the convex ring 124e.

Thus, on the one hand, the convex ring 124e abuts against the side wall of the groove 121d, and has a sealing effect; on the other hand, the bottom of the convex ring 124e abuts against the bottom of the groove 121d, and has a sealing effect. To achieve a double sealing effect. When the upper cover 125 is mounted at the opening 121, the convex ring 124e is inserted into the recess 121d, which greatly enhances the sealing effect of the upper cover 125 and the bottom case 12a. In addition, in order to make the sealing better, the convex ring 124e may be a flexible member such as silica gel, intersecting or latex.

Referring to FIG. 26, in another preferred embodiment, a support post 1211 extending toward the opening 121 may be disposed inside the bottom case 12a, and the upper cover 125 is supported by the support post 1211 to improve The degree of compression resistance of the upper cover 125. The support column 1211 supports the upper cover 125 in a manner of direct support or indirect support, which is not limited herein.

In this embodiment, as shown in FIG. 27 and FIG. 28, the smart bracelet 10 further includes a watch band 11 and a pivot pin 13. One end of the dial 12 is provided with a first slot 12p; the strap 11 includes a connection. a body 11a and a first insertion portion 11b disposed at one end of the connection body 11a, the first insertion portion 11b mating with the first slot 12p, and connecting the dial 12 through the shaft pin 13 The extending direction of the first insertion portion 11b is disposed at an angle to the extending direction of the connecting body 11a.

Specifically, the dial 12 has a front side and a back side (the user wears the smart wristband 10, and the reverse side is in contact with the arm), and the first slot 12p has an opening, a bottom wall opposite to the opening, and a fourth between the opening and the bottom wall. Side walls. The four side walls include a first side wall adjacent to the front surface of the dial 12, a second side wall opposite the first side wall, and oppositely disposed third side walls and fourth side walls. The outer wall of the dial 12 is provided with a mounting hole through which the third side wall and the fourth side wall are inserted, and the shaft pin 13 is installed in the first slot 12p through the mounting hole. The first insertion portion 11b is provided with a shaft hole through which the shaft pin 13 is inserted. The shaft pin 13 is inserted into the first insertion portion 11b, and the opposite ends of the shaft pin 13 are inserted into the two mounting holes, thereby realizing the strap. 11 and the installation of the dial 12.

Referring to Fig. 27, the extending direction of the first insertion portion 11b is set at an angle to the extending direction of the band 11, and the angle means more than 0° and less than 180°. When the angle is greater than 0° and less than or equal to 90°, even if the strap 11 is subjected to the pulling force, the tension of the strap 11 is all transferred to the wall portion of the first slot 12p, and the axle pin 13 is not subjected to the pulling force. The shaft pin 13 is protected. When the angle is greater than 90° and less than 180°, the tension on the strap 11 is carried by the axle pin 13 on the one hand and the wall of the first slot 12p on the other hand, so that the force of the axle pin 13 can also be relieved. To prevent the shaft pin 13 from being deformed due to excessive force.

The technical solution of the embodiment can set the angle of the extension of the first plug portion 11b and the strap connecting body 11a to a certain angle, so that the pulling force received by the shaft pin 13 can be transferred to the wall of the first slot 12p. In addition, the deformation of the shaft pin 13 caused by the excessive force of the shaft pin 13 is avoided, and the stability of the connection between the watch band 11 and the dial 12 is improved.

Referring to FIG. 27 to FIG. 31, the human arm is approximately cylindrical. When the user wears the smart bracelet 10, the angle between the extending direction of the first plug portion 11b and the extending direction of the connecting body 11a is too small to be disadvantageous to the user. Wear it. In the present embodiment, in view of the shape of the human arm, the angle α between the extending direction of the first insertion portion 11b and the extending direction of the connecting body 11a of the watch band 11 is between 90° and 150°. Thus, it is convenient for the user to wear, and most of the pulling force received by the connecting body 11a of the watch band 11 is transferred to the wall portion of the first slot 12p, thereby reducing the force of the axle pin 13.

Referring to Figures 27 and 31, when the strap connecting body 11a is subjected to a pulling force, a part of the pulling force may be shared by the axle pin 13, but once the strap connecting body 11a is subjected to the excessive withdrawal, the first plug portion 11b may The deformation occurs in the first slot 12p, which causes the angle between the extending direction of the first insertion portion 11b and the extending direction of the band 11 to become larger, which also increases the pulling force of the shaft pin 13 once the tension is applied. Exceeding the tolerance of the axle pin 13, the axle pin 13 will be damaged. In a preferred embodiment, referring to FIG. 27, FIG. 34, FIG. 35 and FIG. 36, in order to enhance the stability of the mounting of the first plug portion 11b in the first slot 12p, the first slot 12p includes The first accommodating groove 121p and the second accommodating groove 122p are formed in the outer and outer directions. The first accommodating groove 121p is for partially accommodating the connecting body 11a, and the second accommodating groove 122p is used for The first plug portion 11b is accommodated. In this way, when the strap connecting body 11a receives the pulling force, the pulling force can be shared by the wall portion of the first receiving groove 121p and the wall portion of the second receiving groove 122p, even if the strap 11 is subjected to a large pulling force. Due to the supporting force of the wall portion of the second accommodating groove 122p on the connecting body 11a, the force of the first accommodating groove to the first plug portion 11b is relatively small, and the first plug portion 11b is also difficult to be deformed. The force applied to the axle pin 13 is not too large.

Referring to Fig. 27, Fig. 34 and Fig. 35, when the band 11 is subjected to the pulling force, the first insertion portion 11b is deformed, and the shaft pin 13 is damaged. Before the first plug portion 11b is deformed, the most stressed force is the end of the first plug portion 11b. In this embodiment, in order to provide better protection for the axle pin 13, in an embodiment, the bottom wall and the first side wall are provided with an abutment 12q, and the end of the plug portion is provided with The abutment station 12q is fitted with a notch groove 110. In this way, under the cooperation of the notch groove 110 and the abutment table 12q, the deformation of the end of the first insertion portion 11b is prevented from being excessively deformed, and the axial force is excessively increased, and the band 11 and the dial are increased. 12 assembly stability.

On the basis of the previous embodiment, in order to further strengthen the connection between the watch band 11 and the dial 12, the first slot 12p further has a second side wall opposite to the first side wall, the first A rib 113 is disposed on a surface of the insertion portion 11b facing the second side wall.

The rigid connector 112 can also be fixedly coupled to the dial 12, such as by a screw connection, a snap connection, or the like. The flexible strap 10 is also attached to the rigid connector 112 in a variety of manners, for example, the flexible strap 10 is partially embedded in the rigid connector 112, or the rigid connector 112 is partially embedded in the flexible strap 10, or both. Screw connectors are connected.

The technical solution of the embodiment provides a rigid connecting member 112 at one end of the flexible outer band, so that the flexible wrist band 111 can be connected to the dial 12 through the rigid connecting member 112, thereby ensuring the flexibility of the watch band 10 while enhancing The connection strength between the watch band 10 and the dial 12 improves the stability of the connection between the watch band 10 and the dial 12.

In order to improve the stability between the flexible wristband 111 and the rigid connector 112, in the embodiment, the flexible wristband 111 and the rigid connector 112 are integrally molded by overmolding. The hard connector 112 has a higher melting point, and the rigid connector 112 can be first produced by injection molding, and then the rigid connector 112 is placed in the mold together with the material from which the flexible wristband 111 is made, by overmolding. The material of the flexible wristband 111 is exemplified by silica gel. In the process of overmolding, since the melting point of the silica gel is low, when the injection temperature reaches the melting point of the silica gel, the silica gel melts, and the hard connector 112 does not melt, thus, hard The mass connector 112 can be embedded in the flexible wristband 111, or the flexible wristband 111 can be embedded in the rigid connector 112, thereby greatly enhancing the stability of the connection.

In the above embodiment, referring to Figs. 28, 34 and 35, the flexible wrist band 111 and the rigid connecting member 112 are mutually engageable. If the flexible wristband 111 is embedded in the rigid connector 112, it is necessary to provide a mounting slot for the wristband to be inserted into the rigid connector 112, thus increasing the complexity of the injection molding of the rigid connector 112. The product rate has increased greatly and the manufacturing cost has also increased. In view of the above, in the embodiment, the rigid connector 112 includes a second insertion portion 112b, and one end of the flexible wristband 111 is provided with a second for inserting the second insertion portion 112b. The slot 1110 extends along the length of the flexible wristband 111. Described herein is a structure in which the flexible wristband 111 is formed. Before molding, the material of the flexible wristband 111 is attached to the surface of the second insertion portion 112b. After cooling, the second insertion portion 112b and the flexible wristband are cooled. 111 integrated molding.

In addition to the previous embodiment, in order to increase the rigidity of the connection between the second insertion portion 112b and the flexible wristband 111, the second insertion portion 112b is provided with a concave-convex structure.
