Referring to fig. 1, a wearable device 1000 is provided in the embodiment of the present application, where the wearable device 1000 includes a circuit board 10 and a bottom case 210. The circuit board 10 includes a main body portion 11 and a pressure sensing portion 12 opposite to the main body portion 11. The pressure sensing part 12 can be turned 180 ° relative to the main body part 11 and then stacked to fit the inner side of the bottom case 210. The pressure sensing part 12 acquires a pressure signal through the bottom case 210. The pressure sensing part 12 acquires a sensing signal to detect information of the user using the wearable device 1000. The wearable device 1000 may be a smart watch, a smart bracelet, a smart wristband, or a smart headset.
By the circuit board 10 including the main body portion 11 and the pressure sensing portion 12 opposite to the main body portion 11, the pressure sensing portion 12 can be turned 180 ° relative to the main body portion 11 and stacked to be attached to the inner side of the bottom case 210, that is, the pressure sensing portion 12 can be easily assembled to the inner side of the bottom case 210 after being turned relative to the main body portion 11, so that the assembly convenience of the wearable device 1000 is improved, and the requirement of sensing the wearing pressure is met.
Referring to fig. 2, 3 and 4, in the present embodiment, the circuit board 10 further includes a first bendable portion 13. The first bendable portion 13 is connected to the main body portion 11 and the pressure sensing portion 12. The pressure sensing part 12 can be stacked with the main body part 11 as the first bendable part 13 is bent. The pressure-sensitive portion 12 is provided with a pressure-sensitive antenna 20. The wearable device 1000 can obtain the wearing pressure by using the pressure sensing antenna 20 to detect the information of the user using the wearable device. The wearable device can be a smart watch, a smart bracelet, a smart wristband, or a smart headset.
Through the pressure sensing antenna 20 is integrated on the pressure sensing part 12 of the circuit board 10, the pressure sensing antenna 20 and the circuit board 10 are integrated, so that the difficulty in assembling the pressure sensing antenna 20 and the circuit board 10 is avoided, and the assembling convenience of the wearable device 1000 is improved.
In this embodiment, the circuit board 10 is a flexible circuit board. When the circuit board 10 is applied to the wearable device 1000, and the wearable device 1000 is used for being worn by a user, both the main body portion 11 and the pressure sensing portion 12 can be bent and deformed, so that the wearable device 1000 can have flexible deformation performance, and further the wearable device 1000 can be more attached to the body of the user, and the wearing comfort level is increased. The circuit board 10 includes a flexible base layer 14, a wiring layer 15 attached to the flexible base layer 14, and a protective layer 16 covering the wiring layer 15. The wiring layer 15 may be a copper foil wiring. The wiring layer 15 is electrically connected to the pressure-sensitive antenna 20. The circuit layer 15 may be disposed on both sides of the flexible substrate 14, or may be disposed on one side of the flexible substrate 14. The circuit layer 15 transmits electrical signals to the pressure sensitive antenna 20. The main body portion 11 may be further provided with a plurality of functional devices, and the plurality of functional devices may be electrically connected to the wiring layer 15. The plurality of functional devices may include a processor that may process signals sensed by the pressure sensing antenna 20 and a memory that may store signals. A plurality of functional devices may be arranged on the circuit board 10, making full use of the layout area of the circuit board 10, and achieving the versatility of the sensor assembly 100.
In this embodiment, the area of the main body 11 is larger than the area of the pressure sensing part 12, so that the main body 11 can effectively support the pressure sensing part 12, and the structure of the circuit board 10 is stable after the pressure sensing part 12 is turned and stacked relative to the main body 11. After the pressure sensing portion 12 is turned and stacked relative to the main body portion 11, the first bendable portion 13 is bent and deformed, and in order to reduce the resistance of the pressure sensing portion 12 to turning and stacking relative to the main body portion 11, the internal stress of the first bendable portion 13 is smaller than the internal stress of the main body portion 11 and smaller than the internal stress of the device arrangement. The first bendable part is approximately in a long strip shape. The length of the first bendable portion 13 is greater than the distance from the pressure sensing portion 12 to the main body portion 11. The thickness of the first bendable portion is smaller than the thickness of the main body portion 11 and smaller than the thickness of the pressure sensing portion 12.
In this embodiment, the pressure-sensitive antenna 20 may be attached to the flexible base layer 14. The protective layer 16 may cover the pressure-sensitive antenna 20 to protect the pressure-sensitive antenna 20. The pressure sensing antenna 20 can acquire sensing signals through the protection layer 16. The pressure-sensitive antenna 20 may be made of a conductive material such as graphene. The pressure-sensitive antenna 20 has good conductive characteristics, and good pressure-sensitive characteristics. When the user wears the wearable device 1000 having the circuit board 10, the pressure-sensitive antenna 20 senses the wearing pressure of the user, thereby detecting that the user wears the wearable device 1000. The pressure sensing antenna 20 is thin, and is conveniently integrated on the circuit board 10, thereby avoiding the difficulty in assembling the pressure sensing antenna 20 and the circuit board 10. The pressure sensing antenna 20 is disposed on one side of the flexible base layer 14, when the pressure sensing portion 12 is turned over and stacked relative to the main body portion 11, the pressure sensing antenna 20 is located on one side of the pressure sensing portion 12 away from the main body portion 11, so that after the sensor assembly 100 is worn by a user, the pressure sensing antenna 20 is closer to the body of the user, and the pressure sensing antenna 20 senses the wearing pressure of the user and is more sensitive. The pressure-sensitive antenna 20 can be arranged on the pressure-sensitive portion 12 by adopting a preset pattern, so that the pressure-sensitive antenna 20 can set the size of the sensing area as required and the shape of the sensing area as required, so as to satisfy that the pressure-sensitive antenna 20 can be arranged on the pressure-sensitive antenna 20 with different structures according to different body positions of the wearable device worn by the user, thereby increasing the sensing performance of the sensor assembly 100. Of course, in other embodiments, the pressure-sensing antenna 20 may also be embedded inside the flexible base layer 14, so that the pressure-sensing antenna 20 is integrated with the pressure-sensing portion 12. The protection layer 16 may also be a hollow portion facing the pressure-sensitive antenna 20, so that the resistance of the pressure-sensitive antenna 20 to acquire the sensed pressure signal is smaller.
Further, referring to fig. 5 and 6, the circuit board 10 further includes a second bendable portion 17 and a connection port 18, the second bendable portion 17 is connected to the main body portion 11, and the connection port 18 is fixed to an end of the second bendable portion 17 away from the main body portion 11.
In the present embodiment, a distance exists between the second bendable portion 17 and the first bendable portion 13. The second bendable portion 17 and the first bendable portion 13 are respectively connected to two edges of the main body portion 11, so that the bending stress of the second bendable portion 17 and the first bendable portion 13 on the main body portion 11 can be dispersed, and the main body portion 11 is prevented from being easily deformed by too much bending stress. The second bendable portion 17 transmits an electrical signal to the connection port 18 and the main body portion 11, and when the second bendable portion 17 is in a bent and deformed state, the connection port 18 can be turned over relative to the main body portion 11, so that the connection port 18 of the circuit board 10 can be conveniently assembled on a main board in a wearable device. The pressure sensing antenna 20 can transmit and receive electrical signals through the connection port 18, facilitating the application of the sensor assembly 100 in wearable devices.
In the bent and deformed state of the second bendable portion 17, the connection port 18 may be turned over relative to the main body portion 11 to a state stacked with the main body portion 11, or may be turned over relative to the main body portion 11 to a state staggered from the main body portion 11.
After the second bendable part 17 is bent, the connection port 18 is turned over relative to the main body part 11, and a hollow area of the circuit layer 15 can be arranged on a side of the connection port 18 away from the main body part 11, so that the connection port 18 can be connected with a main board of a wearable device conveniently.
When the connection port 18 is turned over relative to the main body 11, the surface of the connection port 18 away from the main body 11 is connected to the main board, so that the circuit board 10 can be wired on a single surface, the structure of the circuit board 10 is simplified, and the sensor assembly 100 is convenient to mount. The connection port 18 may be electrically connected to the main board of the wearable device 1000, so that the second bendable portion 17 and the connection port 18 constitute a main board connection portion of the circuit board 10, and the main board connection portion is separated from the pressure sensing portion 12, thereby preventing electromagnetic interference of the main board connection portion with the pressure sensing portion 12 and improving the sensing performance of the pressure sensing portion 12.
Of course, in other embodiments, the circuit layers 15 are disposed on both sides of the flexible base layer 14 of the circuit board 10, and the connection port 18 and the pressure-sensitive antenna 20 may be connected to the circuit layers 15 on the opposite sides of the flexible base layer 14.
Further, the connection port 18 is provided with a circuit board connector 181, and the second bendable portion 17 is provided with a connector cover portion 171 which is stackable with respect to the circuit board connector 181.
In the present embodiment, the connector covering portion 171 is spaced apart from the connection port 18. A portion between the connector covering portion 171 and the connection port 18 is bendable so that the connector covering portion 171 covers the connection port 18 in a state of being overturned relative to the connection port 18. The circuit board connector 181 may be a connection plug of a board-to-board connector. The circuit board connector 181 is disposed on one surface of the connection port 18. After the connection port 18 is turned over relative to the main body 11, the connector cover portion 171 covers the connection port 18, and the circuit board connector 181 is located at the connection port 18 and away from the connector cover portion 171, so as to facilitate connection of the circuit board connector 181 with a main board of a wearable device.
By providing the connector cover portion 171 to cover the circuit board connector 181 such that the second bendable portion 17 is stacked with the connection port 18, the arrangement area of the circuit board 10 is reduced. The connector covering portion 171 covers the connection port 18, and the connection port 18 can be stress-supplemented by the connector covering portion 171, so that the plug-in stability of the connection port 18 and a main board of a wearable device is improved. The stress of the connector covering portion 171 is greater than that of the portion between the connector covering portion 171 and the connection port 18, so as to ensure the safety of the circuit board 10 and facilitate the assembly of the sensor assembly 100 with the main board of the wearable device.
Further, the second bendable portion 17 is provided with an elongated extension 172 spaced apart from the connector cover portion 171, and a portion between the connector cover portion 171 and the elongated extension 172 is bendable.
In this embodiment, the second bendable portion 17 is provided with the extension 172, so that the length of the second bendable portion 17 can be extended to increase the bending deformation performance of the second bendable portion 17. The elongate extensions 172 may extend linearly. The portion between the elongated extension 172 and the connector cover portion 171 can be bent, so that the distance between the connection port 18 and the connector cover portion 171 to the main body portion 11 can be adjusted, and the connection port 18 can be conveniently connected with a main board of a wearable device. Of course, in other embodiments, the extension 172 may extend along a curve.

It will be appreciated that the second bendable portion 17 extends in a curve. The end of the second bendable portion 17 connected to the main body 11 can be bent with respect to the main body 11, so that the extension 172 can be turned over with respect to the main body 11, thereby simplifying the structure of the circuit board 10 and facilitating the installation. The portion of the second bendable portion 17 connecting the end of the main body portion 11 to the extension portion 172 is bendable, so that the extension portion 172 can maintain the unfolded state and maintain the state that the connection port 18 is always away from the end of the second bendable portion 17 connecting the main body portion 11, to ensure the safety of the connection port 18 and prevent the connection port 18 from being damaged by the bending stress of the second bendable portion 17.

The first notch 115 is substantially rectangular channel shaped. The first bendable portion is connected to the bottom edge of the first notch 115, so that the first bendable portion and the main body portion 11 can be partially overlapped, the occupied area of the first bendable portion 13 and the main body portion 11 is reduced, the length of the first bendable portion 13 is increased, the first bendable portion 13 can be conveniently bent, the pressure sensing portion 12 and the main body portion 11 can be conveniently turned and stacked, and the mounting difficulty of the sensor assembly 100 is reduced.
In this embodiment, the edge of the pressure sensing part 12 is provided with a second notch 121. One end of the first bendable portion 13 away from the main body portion 11 extends to the bottom of the second notch 121. The second notch 121 is opposed to the first notch 115 in a state where the device row portion is stacked on the body portion 11.

The extending direction of the second notch 121 is substantially parallel to the radial direction of the pressure sensing part 12. The size of the second notch 121 is substantially the same as the size of the first notch 115. The first bendable portion is connected to the bottom edge of the second notch 121 by the bottom edge of the first notch 115, so that the length of the first bendable portion 13 is increased to ensure effective bendability of the first bendable portion 13, and the influence of bending stress of the first bendable portion 13 on the main body portion 11 and the pressure sensing portion 12 is reduced, and the occupied space of the sensor assembly 100 can be effectively reduced.
