[0041] Combine the following Figure 1-Figure 7 The circuit board 120 and the wearable device 10 provided in the present application are described.

[0042] See also Figure 1-Figure 3 The embodiment of the present application provides a circuit board 120 for a wearable device 10, and the circuit board 120 includes a substrate 121, a controller, a vital sign sensor 122, and a trigger switch 123. The substrate 121 is flexibly set and can be configured to allow bending into a ring shape. The substrate 121 with a ring shape is small in size and can match the shape of wearable devices such as rings and bracelets. On the other hand, it can also increase the installation area. With the same volume, more installation space can be provided, which is conducive to the reasonable arrangement of components. After being bent, the substrate 121 has an inner side 1211 and an outer side 1212. The substrate 121 can be bent once or multiple times, and the present application does not limit this.

[0043] Furthermore, the substrate 121 is provided with a track line for electrical connection, and the track line can electrically connect various components. In the technical solution provided in the present application, the controller is arranged on the substrate 121, and can be arranged on the inner side 1211 or on the outer side 1212; the vital sign sensor 122 is electrically connected to the controller by the track line, and the vital sign sensor 122 is arranged on the inner side 1211. When the user wears the electronic device, the vital sign sensor 122 just corresponds to the wrist or finger of the user, and can detect the wearer's vital signs, which may include heart rate, blood oxygen, blood pressure or temperature, etc.; the trigger switch 123 is electrically connected to the controller by the track line, and the trigger switch 123 is arranged on the outer side 1212. When the user wears the electronic device, the trigger switch 123 just corresponds to the outside (outside) of the device, which is convenient for the user to operate or abut against the external component (such as the second ring body 200 below). The trigger switch 123 can be a micro switch, a switch contact, or a pot switch, etc. Specifically, a button or other touch element may be provided on the wearable electronic device to trigger the trigger switch 123 to input a trigger signal. The trigger signal may correspond to the selection or control of a function of the wearable electronic device, or the selection or control of a function of other interactive devices.

[0044] It should be noted that the circuit board 120 provided in the present application has a flexible base 121 that can be configured to be bent into a ring shape. The bent circuit board 120 has an inner side 1211 and an outer side 1212, which is suitable for wearable devices such as bracelets and rings. The inner side 1211 of the base 121 can be installed with a vital sign sensor 122, which is used to correspond to the user's wrist or finger to detect the user's vital signs; the outer side 1212 can be provided with a trigger switch 123, which is convenient for the user to touch and operate the corresponding wearable device function. Through the above-mentioned structural setting of the circuit board 120, on the one hand, wearable devices such as bracelets and rings can be further miniaturized, making the device more beautiful and improving the user's experience. On the other hand, more installation positions can be provided for components while reducing the volume, which is conducive to the reasonable distribution of components in the wearable device 10.

[0045] In order to facilitate the charging of the wearable device 10, the circuit board 120 also includes a charging coil 124, which is electrically connected to the controller through a track line and can be configured to electrically sense an external charging device as a charging receiving end. It should be noted that the charging coil 124 can actually be arranged on the inner side 1211 or the outer side 1212 of the circuit board 120, but considering that the charging coil 124 arranged on the outer side 1212 may cause charging inconvenience, in one embodiment provided in the present application, the charging coil 124 is located on the inner side 1211 of the substrate 121. In this way, when applied to the wearable device 10, the charging area is located on the inner side 1211 of the wearable device 10. It can be understood that the charging coil 124 and the vital sign sensor 122 can be located on the same mounting surface of the substrate 121. Since the two are located on the same side, the vital sign sensor 122 can be directly detected toward the user's skin, and this side can also be matched with a columnar or plate-shaped wireless charging device to achieve a convenient and fast charging effect. In other embodiments, metal contacts may also be provided on the circuit board 120. In this case, a wireless charging coil may not be required, wherein the metal contacts are electrically connected to the battery, and the external charging device may include a wired charging head electrically connected to the metal contacts to charge the battery.

[0046] It should be noted that the trigger switch 123 can be set to one or more. When a switch is set, the number of triggers of the trigger switch 123 can correspond to different control functions, but it may also cause inconvenience in control. In order to improve the convenience of user control, in an optional embodiment, the trigger switch 123 includes multiple, and multiple trigger switches 123 are arranged at intervals along the outer side 1212. By setting multiple trigger switches 123, it is convenient for users to perform trigger operations at various positions of the wearable device 10, and the operation is simpler. It should be noted that the arrangement length of the trigger switch 123 is greater than the sum of the arrangement lengths of the vital sign sensor 122 and the charging coil 124. In this way, the substrate 121 is unfolded and viewed. The trigger switch 123 is arranged in most areas of the substrate 121, which is convenient for users to operate. It should be noted that the functions of each trigger switch 123 can be the same, and the user can achieve the same control effect by triggering at any position; the functions of the trigger switch 123 can also be different, and the user can achieve the same control effect through different trigger switches 123.

[0047] Further, the circuit board 120 also includes a communication module 125, which is electrically connected to the controller through a track line. The communication module 125 is used to communicate with an external device, and the communication module 125 is arranged on the inner side 1211 or the outer side 1212. Through the setting of the communication module 125, when applied to the wearable device 10, the wearable device 10 can connect and interact with other smart devices. The communication module 125 can be a Bluetooth module or a wifi module. When the wearable device 10 is connected and interacted with other smart devices through the communication module 125, on the one hand, information can be sent or received with other smart devices, and on the other hand, the function of other smart devices can be controlled or switched, for example, the trigger switch 123 can be used to control the opening or closing of other smart devices, control the application switching of other smart devices, etc. Other smart devices or external devices can be mobile phones, tablets, desktop computers, near-eye display devices (such as smart glasses, etc.), projection devices, etc.

[0048] In order to further enhance the convenience of operation, the circuit board 120 also includes a capacitive touch sensor 126, which is located between two adjacent trigger switches 123, and the capacitive touch sensor 126 is electrically connected to the controller through a track line. It should be noted that a capacitive touch sensor 126 may be provided between each two trigger switches 123, or a capacitive touch sensor 126 may be provided between local trigger switches 123. The capacitive touch sensor 126 is configured to detect user action input, and the action input is converted into an interactive signal by the controller, and the communication module 125 sends the interactive signal to an external device. For the convenience of control, in an optional embodiment, a capacitive touch sensor 126 is provided between each two adjacent trigger switches 123. In order to reduce the difficulty of operation, the parameters of each capacitive touch sensor 126 are the same, and when the same touch operation is used for each capacitive touch sensor 126, the control signal expressed is the same. In an optional embodiment, a tap operation or a sliding operation, etc., may be selected, corresponding to different control signals.

[0049] As mentioned above, the base 121 has an inner side 1211 and an outer side 1212 after being bent, and the base 121 can be bent once or multiple times. In an optional embodiment, the base 121 can be bent once, that is, the base 121 is completely formed into a ring or arc shape, and the two side surfaces of the base 121 respectively form the inner side 1211 and the outer side 1212. In other optional embodiments, the base 121 includes a first section 1213, a second section 1214 and a connecting section 1215 connecting the first section 1213 and the second section 1214 along the length direction, and the connecting section 1215 is connected between the tail end of the first section 1213 and the head end of the second section 1214, and the side of the first section 1213 away from the second section 1214 forms the inner side 1211 of the base 121, and the side of the second section 1214 away from the first section 1213 forms the outer side 1212 of the base 121. Please refer to Figure 1-Figure 3The first section 1213 and the second section 1214 are configured to be bent into a ring shape, and the first section 1213 is placed in the inner circle and the second section 1214 is placed on the first section 1213 to form an outer circle, and a gap is formed between the first section 1213 and the second section 1214, and the head end of the first section 1213 and the tail end of the second section 1214 face the same direction. That is, the base 121 is bent twice to form the first section 1213, the second section 1214 and the connecting section 1215. The controller, the vital sign sensor 122, the charging coil 124 and the communication module 125 are arranged in the first section 1213, and the multiple trigger switches 123 are arranged in the second section 1214 at intervals. It should be noted that, when the base 121 is unfolded, the controller, vital sign sensor 122, charging coil 124, communication module 125 and trigger switch 123 are actually located on the same side of the base 121, but after the base 121 is bent, the controller, vital sign sensor 122, charging coil 124, communication module 125 and trigger switch 123 are oriented in different directions and are respectively located on the outer side 1212 or the inner side 1211 of the bent base 121. Such an arrangement can improve the strength of the base 121 on the one hand, and on the other hand, arranging related components on the same side and then bending can reduce the process difficulty and improve production efficiency.

[0050] In order to facilitate the stable installation of the base 121 in the wearable device 10, the circuit board 120 also includes a mounting bracket 127. In order to match the shape of the base 121, the mounting bracket 127 is arranged in a ring shape. Further, the mounting bracket 127 is provided with a mounting opening 128, the first section 1213 is arranged on the inner side 1211 of the mounting bracket 127, the connecting section 1215 is passed through the mounting opening 128, and the second section 1214 is arranged on the outer side 1212 of the mounting bracket 127. Through the arrangement of the mounting bracket 127, on the one hand, the base 121 can be easily installed, and on the other hand, the base 121 is flexibly arranged to prevent the base 121 from deforming. Specifically, the trigger switch 123 is arranged along the circumference of the bracket and away from the mounting bracket 127, and the charging coil 124, the vital sign sensor 122 and the communication module 125 are arranged at intervals along the circumference of the mounting bracket 127 and away from the mounting bracket 127.

[0051] Furthermore, the circuit board 120 also includes a battery 129, which is arc-shaped. The battery 129 is electrically connected to the controller, the vital sign sensor 122, the charging coil 124, the communication module 125, and the trigger switch 123 by a track line. In order to protect the battery 129 and to further save installation space, the battery 129 is located on the inner side 1211 of the mounting bracket 127 and in the space surrounded by the second section 1214. The battery 129 can be clamped by the base 121. It can be understood that the base 121 is bent around the circumferential length direction of the battery 129, so from the side, the battery 129 can be clamped between the bases 121. It should be noted that in the above scheme, the controller, vital sign sensor 122, charging coil 124, and communication module 125 are arranged in the first section 1213. Since the above components have a certain volume, the surface of the components arranged in the first section 1213 will exceed the side of the first section 1213, and when applied to the wearable device 10, it will affect the size of the wearing opening and may occupy the area of ​​the wearing opening. Therefore, in an optional embodiment, the area for arranging components in the first section 1213 is bent inward, so that the above components are arranged in the first section 1213, and the end face of the components is kept flush with the surface of the first section 1213, so that the structure can be regularized and space can be further released.

[0052] Specifically, the vital sign sensor 122 includes a first transmitting unit 1221, a second transmitting unit 1222, a receiving unit 1223 and a light-isolating section 1224 located between the communication module 125 and the charging coil 124. The receiving unit 1223 is located between the first transmitting unit 1221 and the second transmitting unit 1222. The light-isolating section 1224 is located between the first transmitting unit 1221 and the receiving unit 1223 and between the second transmitting unit 1222 and the receiving unit 1223. The light-isolating section 1224 can block optical crosstalk to ensure the use effect of the vital sign sensor 122. In an optional embodiment, a light-isolating block can be set to be placed on the side walls of both sides of the receiving unit 1223, or a mounting frame can be set to place the receiving unit 1223, but the two sides of the mounting frame are light-isolating. The vital sign sensor 122 can be used to detect heart rate, blood pressure, blood oxygen, temperature, etc., and this application does not limit this.

[0053] Based on the above circuit board 120, please refer to Figure 4-Figure 7The present application also provides a wearable device 10, comprising: a first ring body 100, a first installation cavity 110 is provided in the first ring body 100, a circuit board 120 is provided in the first installation cavity 110, and a key cap 130, the first ring body 100 is provided with a through hole 140 connected to the first installation cavity 110, the key cap 130 is located in the through hole 140 and at least partially exposed relative to the through hole 140, the key cap 130 corresponds to the trigger switch 123, and the key cap 130 is configured to receive a user's press to trigger the state of the trigger switch 123. It should be noted that the first ring body 100 can be configured to be the size of a ring or a bracelet, and the inner side 1211 of the first ring body 100 has a wearing opening for the user to wear. The circuit board 120 is arranged to match the shape of the first ring body 100, which can make the first ring body 100 more miniaturized and improve the aesthetics. Furthermore, the keycap 130 is disposed on the surface of the first ring body 100 . The keycap 130 has a certain degree of freedom and can be made of an elastic material for user convenience. The user can trigger the trigger switch 123 by pressing the keycap 130 .

[0054] It should be noted that the above-mentioned first ring body 100 can be used alone. In order to improve the use effect, the wearable device 10 also includes a second ring body 200. The first magnet 150 is provided on the upper circumference of the first ring body 100, and the second magnet 210 is provided on the upper circumference of the second ring body 200. The first magnet 150 interacts with the second magnet 210 so that the second ring body 200 is rotatably sleeved on the first ring body 100. It should be noted that the number of the first magnet 150 and the second magnet 210 can be one or more. When the second ring body 200 is sleeved on the first ring body 100, there is a certain gap between the second ring body 200 and the first ring body 100, and the magnetic suspension state can be maintained due to the effect of magnetic force. The user can touch the second ring body 200 to make the second ring body 200 move in the direction close to the first ring body 100, so as to achieve the squeezing effect on the keycap 130 on the first ring body 100, and further trigger the trigger switch 123 to achieve the selection or activation of the function. When the user no longer touches the second ring body 200, the second ring body 200 will move away from the first ring body 100 to maintain the stability of the magnetic suspension. Furthermore, the user can also apply a rotational force to the second ring body 200 so that the second ring body 200 rotates relative to the first ring body 100. When the user is restless, the second ring body 200 can be rotated to divert attention and play a calming role, which can effectively reduce stress and anxiety.

[0055] Specifically, in an optional embodiment, the first magnet 150 and the second magnet 210 are arranged opposite to each other, and the magnetic poles of the first magnet 150 and the second magnet 210 are different. Since the magnetic poles of the first magnet 150 and the second magnet 210 are different, the two can attract each other to reach a stable state, so that the second ring body 200 can be movably sleeved on the outer periphery of the first ring body 100. In an optional embodiment, the magnetic pole of the first magnet 150 facing the second ring body 200 is the S pole, and the magnetic pole of the second magnet 210 facing the first ring body 100 is the N pole. Further, in another optional embodiment, the first magnet 150 and the second magnet 210 are arranged in a staggered manner, and the magnetic poles of the first magnet 150 and the second magnet 210 repel each other. In an optional embodiment, the magnetic pole of the first magnet 150 facing the second ring body 200 is the N pole, and the magnetic pole of the second magnet 210 facing the first ring body 100 is also the N pole, and the magnetic poles of the first magnet 150 and the second magnet 210 repel each other. Due to the staggered arrangement of the two, under the action of magnetic force, gravity and other forces, the first ring body 100 and the second ring body 200 can maintain a magnetic suspension state. In the above embodiment, if the user rotates the second ring body 200, in the process of the first magnet 150 on the first ring body 100 and the second magnet 210 on the second ring body 200 approaching each other, first slowly and then quickly until they are attracted, the rotation process can bring a sense of frustration and increase the feel.

[0056] Due to the addition of the second ring body 200, the first ring body 100 and the second ring body 200 can rotate relative to each other, and specifically there can be two states of counterclockwise rotation and clockwise rotation, and the two states can correspond to different control logics. Specifically, the second section 1214 of the circuit board 120 is also provided with a first magnetic induction component 160 and a second magnetic induction component 170, and the first magnetic induction component 160 and the second magnetic induction component 170 are electrically connected to the controller, and based on the pulse signal between the first magnetic induction component 160 and the second magnetic induction component 170 relative to any second magnet 210, it can be judged that the second ring body 200 is rotating counterclockwise or clockwise, thereby outputting different control logics.

[0057] Specifically, when the second ring body 200 is rotated, the distance between the first magnetic induction component 160 and the second magnetic induction component 170 relative to the second magnet 210 will change, and the magnetic field strength will also change at this time. The controller can confirm whether it rotates clockwise or counterclockwise based on the change of the pulse signal of the magnetic field strength sensed by the first magnetic induction component 160 and the second magnetic induction component 170, and then adjust the external device, such as sliding, turning pages, pulling pages up and down, adjusting the volume, switching songs, etc. The first magnetic induction component 160 and the second magnetic induction component 170 can be Hall devices, the first magnetic induction component 12 and the second magnetic induction component 13 can also be magnetic induction devices with similar functions such as magnetic switches and reed switches, and the first magnet 150 and the second magnet 210 can be magnets.

[0058] The wearable device of the present application can be worn on the user's finger. It is small in size and can be worn lightly without causing any sense of incongruity. The magnetic resistance between the two rings that allows mutual rotation brings stronger playability and stress relief effects. At the same time, the present application can accurately detect the rotation action and form a corresponding interaction instruction through the magnetic sensing part, and can accurately detect the pressing action and form another corresponding interaction instruction through the touch part and the trigger part. The wearable device is designed to be compatible with two different dimensions of interactive operations and external device interactions, and the operability and accuracy of the interaction are effectively improved. In addition, the playability, decorativeness and intelligent interaction are effectively compatible, which greatly improves the application scenarios of the product.

Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
