Health testing has always been an important research direction for smart wearable products. If smart wearable products can be used to collect or monitor heart sounds or lung sounds, it will bring great convenience to users in need. They can collect or test anytime and anywhere, so as to understand their health status in a timely manner.

In order to meet people's desire to know the health status of their heart or lungs at any time, the present application provides a wearable device, which aims to provide a wearable device that is easy to carry and operate for detecting heart sounds or lung sounds.

The wearable device includes a main structure 10, a rotating shaft assembly 30, a connecting portion 50 and a signal acquisition assembly 70. The main structure 10 includes a housing 15 and a mainboard 11 disposed on the housing 15. The rotating shaft assembly 30 is disposed on the housing 15. The connecting portion 50 is connected to the rotating shaft assembly 30 to rotate relative to the housing 15. The signal acquisition assembly 70 includes a physiological sound sensor 71 and a signal transmission structure 73. The physiological sound sensor 71 is used to To detect heart sound signals or lung sound signals, the physiological sound sensor 71 is disposed on the connecting portion 50 and electrically connected to the signal transmission structure 73 . The signal transmission structure 73 is received in the rotating shaft assembly 30 and electrically connected to the main board 11 .

Physiological sounds refer to the sounds produced by mechanical wave phenomena in human organs such as the heart and lungs.

The physiological sound sensor 71 can be a combination of one or more of a bone conduction sensor, a microphone, an acceleration sensor, an inertial sensor, a piezoelectric ceramic, a pressure sensor, or a vibration detection sensor, wherein the number of each sensor can be one or more, or a combination of multiple sensors can be used. For example, the physiological sound sensor 71 is a combination of two bone conduction sensors, or two piezoelectric ceramics, or a bone conduction sensor and an acceleration sensor.

As shown in FIGS. 1 and 2 , the present application provides a wearable device, which includes a main structure 10, a rotating shaft assembly 30, a connecting portion 50, and a signal acquisition assembly 70. The main structure 10 includes a shell 15 and a mainboard 11 disposed on the shell 15. The rotating shaft assembly 30 is disposed on the shell 15. The connecting portion 50 is connected to the rotating shaft assembly 30 to rotate relative to the shell 15. The connecting portion 50 is rotatably connected to the shell 15 through the rotating shaft assembly 30, which is convenient for users to wear. The signal acquisition assembly 70 includes a physiological sound sensor 71 and a signal transmission structure 73. The physiological sound sensor 71 is used to detect heart sound signals or lung sound signals. The physiological sound sensor 71 is disposed on the connecting portion 50 to facilitate placing the connecting portion 50 on the heart or lungs of the chest through The physiological sound sensor 71 collects vibration signals from the heart or lungs. The physiological sound sensor 71 is electrically connected to the signal transmission structure 73. The signal transmission structure 73 is housed in the rotating shaft assembly 30 and is electrically connected to the main board 11. The signal transmission structure 73 is electrically connected to the physiological sound sensor 71 and the main board 11 at the same time, so as to transmit the signal collected by the physiological sound sensor 71 to the main board 11. The main board 11 processes the signal and houses the signal transmission structure 73 on the rotating shaft assembly 30, so that during the rotation of the connecting part 50 relative to the shell 15, the signal transmission structure 73 can adapt to the rotation angle of the shell 15, thereby avoiding pulling on the signal transmission structure 73 and affecting the stability of the electrical connection between the main board 11 and the physiological sound sensor 71 and the signal transmission structure 73.

In this application, the physiological sound sensor refers to a device that can be used to receive vibration signals from the human heart or lungs. The physiological sound sensor uses the conduction method of sound, that is, converting sound into mechanical vibrations of different frequencies, and transmits sound waves through the human skull, bony labyrinth, inner ear lymph, spiral organ, auditory nerve, and auditory center.

Wearable devices refer to devices that are worn on the human body, for example, including those set on the head, face, neck, waist, hands, legs, etc.

The structural scheme of collecting heart sounds or lung sounds of the present application fixes the physiological sound sensor 71 to the connecting part. 50, which is convenient for users to measure, does not occupy the space of the housing 15, and does not affect the overall appearance design of the housing 15.

In the present application, the main board 11 is arranged on the shell 15, and the physiological sound sensor 71 is arranged on the connecting part 50. The two are electrically connected through the signal transmission structure 73 for transmitting signals. For example, when the wearable device is set on the wrist, due to the frequent activities of the human hand and the frequent rotation of the connecting part 50 around the shell 15, a pulling force is bound to be formed between the main board 11 and the physiological sound sensor 71. Long-term pulling can easily cause the signal transmission structure 73 to be easily damaged due to the force. In severe cases, it will cause instability in the electrical connection between the main board 11 and the physiological sound sensor 71 and the signal transmission structure 73, resulting in malfunction when the wearable device is used to detect heart sounds or lung sounds.

Based on this, the present application adopts a rotating shaft assembly 30 to accommodate the signal transmission structure 73. It can be understood that in order to avoid pulling the signal transmission structure 73, the signal transmission structure 73 is reserved with redundant length. In order to facilitate the accommodation of the redundant length of the signal transmission structure 73, the rotating shaft assembly 30 is specifically adopted to accommodate the signal transmission structure 73. For example, the signal transmission structure 73 can be wrapped around the outer circumference of the rotating shaft assembly 30, or a cavity is opened in the rotating shaft assembly 30, and the signal transmission structure 73 is gathered in the cavity. For example, the signal transmission structure 73 is rolled together and directly installed in the cavity to avoid retaining the signal transmission structure 73 outside.

It can be understood that the connecting portion 50 is connected to the rotating shaft assembly 30 so as to rotate relative to the shell 15, wherein the connecting portion 50 can be rotatably connected to the rotating shaft assembly 30, that is, the connecting portion 50 and the rotating shaft assembly 30 can rotate relative to each other, or the rotating shaft assembly 30 is rotatably connected to the shell 15, that is, the connecting portion 50 and the rotating shaft assembly 30 cannot rotate relative to each other, and the connecting portion 50 is rotated relative to the shell 15 by rotating the rotating shaft assembly 30 relative to the shell 15. Alternatively, the connecting portion 50, the rotating shaft assembly 30 and the shell 15 are all rotatably connected, and the specific connection method of the connecting portion 50 and the rotating shaft assembly 30 is not limited.

Furthermore, the rotating shaft assembly 30 includes a connecting shaft 31 and a winding shaft 33 , the connecting shaft 31 is connected to the housing 15 , the connecting portion 50 is rotatably connected to the connecting shaft 31 , the winding shaft 33 is connected to the connecting shaft 31 , and the signal transmission structure 73 is housed in the winding shaft 33 .

As shown in Figure 3, the rotating shaft assembly 30 includes a connecting shaft 31 and a winding shaft 33. The connecting shaft 31 is connected to the shell 15. In order to facilitate the rotation of the connecting part 50 relative to the shell 15, the connecting part 50 is rotatably connected to the connecting shaft 31. At the same time, in order to support or fix the winding shaft 33, the winding shaft 33 is connected to the connecting shaft 31, and the signal transmission structure 73 is housed in the winding shaft 33.

It can be understood that the winding shaft 33 is connected to the connecting shaft 31 , and the winding shaft 33 can be fixedly connected to the connecting shaft 31 , or the winding shaft 33 can be rotatably connected to the connecting shaft 31 , and there is no specific limitation.

Furthermore, the winding shaft 33 is formed with a cavity 331 and a wire-passing hole 333 penetrating the cavity 331 . The signal transmission structure 73 is received in the cavity 331 , and two ends of the signal transmission structure 73 pass through the wire-passing hole 333 .

As shown in FIG4 and FIG5, in order to better accommodate and protect the signal transmission structure 73, the winding shaft 33 is formed with a cavity 331 and a wire hole 333 passing through the cavity 331. The signal transmission structure 73 is accommodated in the cavity 331, and the two ends of the signal transmission structure 73 pass through the wire hole 333. The signal transmission structure 73 is accommodated in the cavity 331 to prevent the signal transmission structure 73 from being exposed to the outside and easily damaged by water and scratches. In order to facilitate the two ends of the signal transmission structure 73 to extend from the cavity 331 to the outside of the cavity 331, so that the two ends of the signal transmission structure 73 are respectively connected to the main board 11 and the physiological sound sensor 71, a wire hole 333 passing through the cavity 331 is formed on the winding shaft 33. It can be understood that the number of the wire holes 333 can be one or more, and the wire holes 333 can be set at the end of the winding shaft 33 or at the circumference of the winding shaft 33, without specific limitation.

It can also be understood that the space of the cavity 331 is greater than or equal to the size of the signal transmission structure 73 after it is rolled up, which is not only convenient for operation but also allows the signal transmission structure 73 to have a certain amount of space for expansion. During the process of rotating the connecting part 50, the signal transmission structure 73 in the cavity 331 can move in the direction of the force, so that when the connecting part 50 rotates, the length of the signal transmission structure 73 can be automatically adjusted according to the rotation angle.

Furthermore, there are two wire-passing holes 333 , and two ends of the signal transmission structure 73 pass through the two wire-passing holes 333 respectively.

As shown in Figures 4 and 5, considering that one end of the signal transmission structure 73 is connected to the main board 11, and the other end is connected to the physiological sound sensor 71, the main board 11 is arranged in the shell 15, and the physiological sound sensor 71 is arranged in the connecting part 50. In most cases, the shell 15 and the connecting part 50 are arranged at a certain angle, that is, the two ends of the signal transmission structure 73 are arranged in different directions. In order to adapt to the position of the main board 11 and the physiological sound sensor 71, two wire holes 333 are arranged, and the two ends of the signal transmission structure 73 pass through the two wire holes 333 respectively. In this way, the signal transmission structure 73 is avoided from being excessively bent, and it is also convenient for the connecting part 50 not to excessively pull the signal transmission structure 73 during the rotation process, so as to avoid affecting the signal transmission structure 73.

Furthermore, the winding shaft 33 is a cylindrical body, two wire passing holes 333 are opened on the side circumference of the cylindrical body, and the angle between the openings of the two wire passing holes 333 is an obtuse angle; and/or, the connecting shaft 31 is connected to the end of the winding shaft 33 so that the winding shaft 33 is fixed to the connecting shaft 31.

As shown in Fig. 4 and Fig. 5, the winding shaft 33 is a cylindrical body having a smooth periphery to avoid Avoid forming sharp corners, avoid discomfort caused by wearing the wearable device on the human body, and also facilitate the rotation of the winding shaft 33. During the rotation of the winding shaft 33, its side surface can face different directions. The two wire holes 333 are opened on the side surface of the cylindrical body. When the connecting part 50 is rotated, the signal transmission structure 73 can drive the cylindrical body to rotate when it is subjected to force, so as to adapt to the force pulling direction of the signal transmission structure 73, and avoid the signal transmission structure 73 being pressed by the hole wall at the wire hole 333, causing damage.

Furthermore, the angle between the openings of the two wire passing holes 333 is an obtuse angle. Considering that the angle between the shell 15 and the connecting part 50 is an obtuse angle in most cases, the angle between the openings of the two wire passing holes 333 is set to an obtuse angle to adapt to the position setting of the shell 15 and the connecting part 50, so as to avoid long-term bending of the signal transmission structure 73 at the intersection where it is connected to the shell 15 and the connecting part 50.

As shown in FIG. 3 , a small hole is formed at at least one end of the winding shaft 33 to facilitate the connection shaft 31 to be inserted into the end of the winding shaft 33 , so that the winding shaft 33 is supported on the connection shaft 31 to prevent the winding shaft 33 from falling off the connection shaft 31 .

It is understandable that a small hole is formed at one end of the winding shaft 33 for connecting to the connecting shaft 31 , and the other end of the winding shaft 33 is open to facilitate the signal transmission structure 73 to be housed in the cavity 331 of the winding shaft 33 .

Furthermore, the connecting part 50 includes a connecting body 51 and a rotating connecting part 55. The connecting body 51 is provided with a mounting groove 53, the physiological sound sensor 71 is arranged in the mounting groove 53, and the rotating connecting part 55 is arranged at the end of the connecting body 51 close to the shell 15, and the rotating connecting part 55 is rotatably connected to the connecting shaft 31.

As shown in Figures 2 and 6, in order to facilitate the installation of the physiological sound sensor 71, a mounting groove 53 is opened on the connecting body 51, and the physiological sound sensor 71 is arranged in the mounting groove 53. At the same time, a rotating connecting part 55 is arranged at the end of the connecting body 51 close to the shell 15, and the rotating connecting part 55 is rotatably connected to the connecting shaft 31.

It can be understood that the rotating connection part 55 is provided with a plug hole, and the connecting shaft 31 is plugged into the plug hole. The rotating connection part 55 can rotate around the connecting shaft 31, so that the connecting body 51 can rotate around the connecting shaft 31.

Furthermore, a fixing groove 531 is formed on the bottom wall 530 of the mounting groove 53 , and the physiological sound sensor 71 is fixed to the fixing groove 531 . The connector 51 is provided with a cover plate 533 at the opening of the mounting groove 53 , and a gap is formed between the cover plate 533 and the physiological sound sensor 71 .

As shown in FIG. 2 and FIG. 6 , in order to further fix the physiological sound sensor 71, the bottom wall 530 of the mounting groove 53 is formed with a fixing groove 531, and the physiological sound sensor 71 is fixed to the fixing groove 531. In order to facilitate the inspection and maintenance of the physiological sound sensor 71, the connector 51 is provided with a cover plate 533 at the opening of the mounting groove 53. By removing the cover plate 533, the physiological sound sensor 71 can be maintained and replaced. A gap is formed between the physiological sound sensors 71. Considering the structural requirements of the physiological sound sensor 71 itself, the physiological sound sensor 71 has its own vibration structure. The gap is formed to avoid the cover from contacting the physiological sound sensor 71 and affecting the reception and transmission of the vibration structure signal.

For example, the physiological sound sensor 71 is a bone conduction speaker 6, a bone conduction speaker 6 as shown in Figure 7, including a magnet 61, a coil 62, a first vibration panel 63, a second vibration panel 64, an elastic connector 65, an adhesive layer 66, and a vibration transmission layer 67; the magnet 61 is arranged on the inner side of the first vibration panel 63, the coil 62 is arranged on the inner side of the second vibration panel 64, one end of the elastic connector 65 is connected to the first vibration panel 63, and the other end of the elastic connector 65 is connected to the second vibration panel 64, and the first vibration panel 63, the elastic connector 65 and the second vibration panel 64 are connected to form a speaker cavity; the adhesive layer 66 is arranged on the outer side of the second vibration panel 64, and the vibration transmission layer 67 is connected to the adhesive layer 66; the vibration transmission layer 67 is an arc structure; the arc structure can well achieve the contact and comfort between the speaker and the wrist, and optimize the bone conduction effect of the speaker.

Further, the connecting body 51 is defined to include an inner side and an outer side, and the mounting groove 53 is opened on the inner side of the connecting body 51; and/or, the mounting groove 53 is arranged at one end of the connecting body 51 close to the shell 15; and/or, the physiological sound sensor 71 is adhesively fixed to the fixing groove 531; and/or, a waterproof structure is provided between the cover plate 533 and the connecting body 51.

The installation groove 53 is opened on the inner side of the connector 51 to avoid increasing the size of the connector 51. At the same time, the installation groove 53 is set on the inner side to set the physiological sound sensor 71 on the inner side to protect the physiological sound sensor 71 and avoid damage to the physiological sound sensor 71 due to bumps.

It can be understood that when the wearable device is set on the wrist, as shown in Figure 2, in order to facilitate the use of the wearable device to monitor the heart or lungs, the physiological sound sensor 71 is set on the connecting part 50, so that the connecting part 50 of the wearable device can be directly set at the heart or lungs, and the heart or lungs can be directly monitored without removing the wearable device. For this purpose, the connector 51 is defined to include an inner portion and an outer portion, and a mounting groove 53 is formed between the inner portion and the outer portion, that is, the mounting groove 53 is opened on the inner side of the connector 51; it can be understood that the side of the connector 51 that is in contact with the skin is the inner portion, and the side away from the skin is the outer portion, and the mounting groove 53 is arranged on the outer portion of the connector 51, so that the bottom wall 530 of the mounting groove is formed on the outer side of the connector 50, and the physiological sound sensor 71 is directly installed on the bottom wall 530 of the mounting groove. In the process of detecting heart sounds or lung sounds, the bottom wall 530 of the mounting groove is directly set at the heart or lung part of the chest, and the vibration of the heart or lung part is transmitted to the bottom wall 530 of the mounting groove. Since the bottom wall 530 of the mounting groove is in direct contact with the physiological sound sensor 71, the vibration loss is smaller, and the detection effect of heart sounds or lung sounds is better.

At the same time, the mounting groove 53 is disposed at one end of the connector 51 close to the housing 15 , so that the mounting groove 53 is closer to the housing 15 , thereby preventing the signal transmission structure 73 from being too long.

In order to reduce the interference of detection and the stability of the physiological sound sensor 71, the physiological sound sensor 71 is bonded and fixed to the fixing groove 531 to avoid detection noise caused by the physiological sound sensor 71 being unstable. For example, the physiological sound sensor 71 can be fixed in the fixing groove 531 by double-sided tape or glue, and of course the physiological sound sensor 71 can also be clamped and limited in the fixing groove 531.

In order to prevent water from entering the installation groove 53 , a waterproof structure is provided between the cover plate 533 and the connector 51 . For example, the cover plate 533 is fixed to the connector 51 by a waterproof double-sided adhesive tape, or a sealing ring is provided between the cover plate 533 and the connector 51 .

It can be understood that the signal transmission structure 73 is a flexible circuit board, so that the signal transmission structure 73 has better mobility when being bent.

It can be understood that the connector 51 is made of soft rubber material, which makes it more comfortable to wear.

When collecting heart sounds or lung sounds, the vibrations generated by the human heart or lungs are directly transmitted to the connector 51 through the clothes, and then transmitted to the physiological sound sensor 71 through the connector 51 to complete data collection. During the collection process, because the physiological sound sensor 71 is fixed to the bottom wall 530 of the mounting groove, the bottom wall 530 of the mounting groove is equivalent to the eardrum to facilitate vibration transmission, and the vibrations of the heart or lungs are transmitted to the physiological sound sensor 71.

The winding shaft 33 is placed in the avoidance area 550 of the rotating connector 55 of the connecting part 50, and then the connecting shaft 31 is connected to the fixing part 13 of the housing 15, and then the rotating connector 55 is docked with the connecting shaft 31 to achieve the installation of the connecting part 50.
