A wearable device according to an embodiment of the present application is described below with reference to fig. 1 to 4.

As shown in fig. 1, a wearable device 10 is provided according to one embodiment of the present application. The wearable device 10 includes a center frame 100, a circuit board 110, a first key 120, and a connector 130.

Specifically, the first button 120 is movably disposed on the middle frame 100, and one end of the first button 120 penetrates through the middle frame 100. The circuit board 110 is bent, and the switch 112 is disposed on the circuit board 110. Specifically, the circuit board 110 includes a body 1100, a connection portion 1104, and a bending portion 1102. One end of the bent portion 1102 is connected to the body 1100, and the other end of the bent portion 1102 is connected to the connection portion 1104. The switch 112 is disposed on the side of the body 1100 near the connection portion 1104. A portion of the connection 130 is disposed between the connection 1104 and the switch 112. The connecting member 130 is connected to the first button 120. And the connecting member 130 cooperates with the first button 120 to clamp the circuit board 110. When the first button 120 is pressed, the connecting member 130 is driven to trigger the switch 112. The switch 112 may be used for power-on, volume control, menu selection, etc.

According to the wearable device 10 of the embodiment of the present application, the wearable device 10 is provided with the middle frame 100, the circuit board 110, the first key 120, and the connector 130. The circuit board 110 is provided with a switch 112. It is understood that the first button 120 is movably disposed on the middle frame 100, and one end of the first button 120 penetrates through the middle frame 100. The connecting piece 130 is partially arranged between the connecting part 1104 of the circuit board 110 and the switch 112 and connected with the first key 120, so that the first key 120 can be fixed, the connection reliability is good, and the problem that the key falls off by a user can be avoided. The connecting member 130 cooperates with the first button 120 to hold the circuit board 110, and can also lock the circuit board 110 and the first button 120 to keep constant contact. When the user presses the first button 120, the first button 120 and the connecting member 130 move simultaneously, and the connecting member 130 correspondingly presses the switch 112, so that the switch 112 arranged on the circuit board 110 can be triggered. Because the connecting piece 130 can directly trigger the switch 112, the circuit board 110 does not need to be additionally provided with an additional elastic sheet, thereby saving materials and ensuring the hand feeling of the first key. It should be noted that the circuit board 110 is clamped by the connecting member 130 and the first button 120, so that the first button 120 can be constantly contacted with the circuit board 110, which is beneficial to realizing direct electrical connection between the first button 120 and the circuit board 110, and thus, a spring plate arranged on the circuit board 110 can be omitted for electrical connection, and materials are saved.

As shown in fig. 4, it can be understood that the circuit board 110 is bent by the bending portion 1102, so that the circuit board 110 is connected to the connecting element 130 and the first button 120, and the connecting element 130 is opposite to the switch 112, so that the connecting element 130 triggers the switch 112 along with the pressing of the first button 120.

In the above embodiment, the circuit board 110 is provided with the first through hole 114. The connecting member 130 passes through the first through hole 114 and is connected to the first button 120. The first through hole 114 is formed in the circuit board 110, so that the first through hole 114 can limit the lateral displacement of the connecting member 130, or limit the lateral displacement of the circuit board 110, thereby being beneficial to preventing the circuit board 110 from being separated from the connecting member 130 and the first key 120, ensuring that the connecting member 130 and the first key 120 are kept connected with the circuit board 110, facilitating the clamping of the circuit board 110, and ensuring the effective connection of electrical performance. The connecting member 130 may be a screw, and a screw cap clamps the circuit board 110 with the first button 120, so that the circuit board 110 and the first button 120 are always in contact, thereby ensuring effective electrical connection.

Specifically, the connection member 130 includes a connection rod 1300 and a stopper 1302 connected to each other. The middle frame 100 is provided with a second through hole, and the connecting rod 1300 passes through the second through hole to be connected with the first button 120. The connecting rod 1300 and the second through-hole are clearance-fitted to facilitate the installation of the connecting rod 1300. The position-limiting portion 1302 is located between the connecting portion 1104 of the circuit board 110 and the switch 112, or the position-limiting portion 1302 is located on a side of the connecting portion 1104 close to the switch 112. The position-limiting portion 1302 is used for clamping the circuit board 110 in cooperation with the first key 120. It can be understood that the cross-sectional area of the position-limiting portion 1302 is larger than the cross-sectional area of the connecting rod 1300 and is also larger than the area of the first through hole 114, so as to ensure that the position-limiting portion 1302 does not pass through the first through hole 114, thereby achieving the purpose of cooperatively clamping the circuit board 110 by the position-limiting portion 1302 and the first key 120.

In some embodiments, the circuit board 110 is provided with a copper exposed area 116, and the first key 120 is an electrical conductor. As long as the first key 120 is in contact with the bare copper area 116, the electrical connection between the first key 120 and the circuit board 110 can be achieved. Therefore, the original elastic sheet arranged on the circuit board 110 can be eliminated, the purpose of electrically connecting the first key 120 and the circuit board 110 can be realized, materials can be saved, and the hand feeling when the first key 120 triggers the switch can be improved. The first button 120 is electrically connected to the circuit board 110, so that the first button 120 is used as an electrode in contact with a human body for performing detection such as electrocardiogram.

In a further embodiment, the first key 120 is not directly in contact with the exposed copper area 116 for electrical connection, but is electrically connected through the connecting member 130. Specifically, the copper exposed area 116 is disposed on a side of the circuit board 110 away from the first key 120, that is, a side of the bent circuit board 110 facing the switch 112, and more specifically, the copper exposed area 116 is disposed on a side of the connection portion 1104 of the circuit board 110 facing the switch 112. And the stopper 1302 of the connecting member 130 contacts the bare copper area 116. Meanwhile, the first button 120 and the connecting member 130 are both electrical conductors. The copper exposing area 116 is arranged on the surface of the circuit board 110, which is in contact with the connecting piece 130, so that the purpose that the first key 120 is electrically connected with the circuit board 110 through the connecting piece 130 can be achieved, an original elastic sheet connected with the circuit board 110 can be omitted, materials and space are saved, and the hand feeling of the first key 120 is guaranteed. That is, the electrical connection between the first key 120 and the circuit board 110 can be achieved. Thus, the first button 120 can be used as an electrode, which is beneficial to detecting the human body only by electrical connection when the human body contacts with the first button 120. For example, for ECG testing, the first button 120 can be used as an electrode for ECG testing. And the copper exposure area 116 is disposed on a side facing the switch 112, that is, a side facing away from the middle frame 100, which is beneficial to reducing or avoiding electromagnetic interference with the middle frame 100, and improving the stability and reliability of the operation of the wearable device 10. The connecting member 130 may be a screw, the connecting rod 1300 is a shaft of the screw, and the position-limiting portion 1302 is a nut. The exposed copper area 116 on the circuit board 110 is in contact with the position-limiting portion 1302, which can function as an electrical connection between the circuit board 110 and the screw, thereby realizing the connection between the circuit board 110 and the first key 120.

In some embodiments, the connecting member 130 is bolted to the first key 120. The connecting member 130 may be a screw, and the screw is bolted to the first button 120, and the screw and the circuit board 110 are locked into the threaded hole of the first button 120 by a locking tool, so as to fix the first button 120 and the middle frame 100, and simultaneously, the first button 120 can be electrically connected to the circuit board 110 by a screw cap. The screw connection reliability is good, and the problem that the first key 120 falls off can be avoided. And the bolt is adopted, so that the assembly and disassembly are convenient, the assembly process is simple, and the operation is easy.

As shown in fig. 2, more specifically, the connecting rod 1300 of the connecting member 130 is provided with external threads. One end of the first button 120 is provided with a screw hole 1200, and the side wall of the screw hole 1200 is provided with an internal thread. The connection rod 1300 and the first button 120 are bolted by the engagement of the external threads and the internal threads of the screw hole 1200. The bolting mode can tightly connect the first button 120 and the connecting member 130, and clamp the circuit board 110, the clamping force is also adjustable, and the convenience of connecting the first button 120 and the circuit board 110 is improved. Meanwhile, in the bolting mode, the first key 120 is electrically connected with the circuit board 110 through the limiting portion 1302, that is, the screw cap, so that an original elastic sheet connected with the circuit board 110 can be eliminated, materials and space are saved, and the hand feeling of the first key 120 is ensured. The screw connection reliability is good, and the problem that the first key 120 falls off can be avoided.

As shown in fig. 3, it can be understood that the end of the connecting member 130 is polygonal or elliptical when it is a screw. The polygonal or oval end portion facilitates locking of the connecting member 130 and the first button 120 with a corresponding tool during assembly.

In other embodiments, the connector 130 is engaged with the first button 120. The first button 120 can be connected to the circuit board 110 through the connector 130 by using a clamping manner, and the first button 120 can be electrically connected to the circuit board 110 through the connector 130.

In still other embodiments, a portion of the connecting bar 1300 is bonded to the first button 120. It should be noted that, by using the bonding method, the connection rod 1300 and the first button 120 are generally connected by dispensing, which not only can ensure the purpose of holding the circuit board 110 and connecting the first button 120 and the circuit board 110, but also the first button 120 has no dispensing position and contacts with the connection rod 1300, thereby achieving the electrical connection function with the circuit board 110 through the connection member 130, and thus eliminating the spring plate. For example, a hole is formed at one end of the first button 120, the connecting rod 1300 of the connecting member 130 is inserted into the hole, one circumferential side of the connecting rod 1300 inserted into the hole is adhered to a hole wall of the first button 120, and the other circumferential side of the connecting rod 1300 is in contact with the hole wall, so that the first button 120 is electrically connected to the circuit board 110 through the connecting member 130.

In other embodiments, the connection bar 1300 and the first button 120 are adhered by a conductive adhesive, so that the connection bar 1300 and the first button 120 can be electrically connected by the conductive adhesive directly regardless of whether they are in contact or not.

In any of the above embodiments, the wearable device 10 further comprises a bio-signal sensor, such as an electrocardiogram sensor, a blood pressure sensor, a heart rate sensor, or the like. The bio-signal sensor is connected to the first button 120 through the circuit board 110. The bio-signal sensor is used for detecting bio-signals. When the user touches the first key 120, the first key 120 functions as an electrode, so that the detection of the bio-signal can be achieved. For example, the bio-signal sensor is an electrocardiogram sensor, and it is understood that the heart generates a weak bio-current at the contraction and relaxation, and the bio-current can be transmitted to the surface of the human body. By monitoring the current changes generated by the periodic changes of the heart through the electrocardiogram sensor, whether the user suffers from diseases related to the heart can be checked.

In the above embodiment, the wearable device 10 further includes a housing, a second key, and a third key. The middle frame 100 is disposed on the housing. The second key is arranged at the bottom of the shell. The third button is arranged at the bottom of the shell.

When a user wears the watch on the arm and touches the first key 120 with a finger, the first key 120, the second key and the third key are respectively used as electrodes to simultaneously contact with the human body, so that the detection function of the electrocardiogram sensor is triggered. It should be noted that, when the first key 120 is used as an electrode, the first key 120 only needs to be in contact with a human body, and does not need to be pressed. When the first button 120 needs to trigger the switch 112, the first button 120 needs to be pressed.
