[0003] The present application relates to the technical field of terminal, and in particular to a wristband, a main body and a wearable electronic device. BACKGROUND

[0004] With the development of science and technology, electronic devices are developing towards function integration and structure portability, bringing convenience and ease to consumers' daily life. Among them, wearable electronic devices can integrate communication, video, health monitoring and other functions, and are widely used in daily exercise and basic health parameter monitoring.

[0005] Currently, the common health functions of wearable devices mainly include measuring heart rate, blood oxygen concentration, respiratory rate, body temperature, electrocardiogram, etc. There is no mature wearable device that can perform real-time and accurate blood pressure monitoring. SUMMARY

[0006] The present application provides a wristband, a main body and a wearable electronic device, which have blood pressure monitoring function and can perform real-time and accurate blood pressure monitoring for users, providing better user experience.

[0007] In a first aspect, the present application provides a wristband which can be used to bind to the wrist of a user. The wristband includes a band body, an air bag structure, a sensor and an electrical connection structure. The band body has a first surface and a second surface opposite in the thickness direction, and the first surface is used to contact the skin of the user's wrist. The band body includes a first air flow port provided with a gas guide channel, and the first air flow port is provided with an electrical connection terminal. The air bag structure is fixed to the first surface of the band body, and the air bag structure has an air cavity for communicating with the gas guide channel of the first air flow port.

One end of the electrical connection structure extends into the air cavity and is electrically connected with the sensor, and the other end of the electrical connection structure is electrically connected with the electrical connection terminal.

[0008] The wristband integrates the electrical connection terminal for electrically connecting the sensor into the first air flow port, and combines and integrates the electrical connection part and the air communication part of the wristband. When the wristband is connected to the main body, electrical connection and air communication can be realized through the first air flow port. When the wristband is buckled on the wrist of the user, the air cavity of the air bag structure is inflated, and the air bag structure expands in volume after inflation and presses the wrist of the user. At this time, the sensor can be used to detect the pulse wave of the user, and the blood pressure value of the user can be obtained by analyzing and processing the pulse wave signal. The operation is convenient, the detection precision is high, and better use experience can be brought to the user.

[0009] In some possible implementations, the first air flow port includes a first base body and a first support, and the first base body and the first support enclose a gas guide channel, and the electrical connection terminal is fixed to the first support.

DETAILED DESCRIPTION

[0071] Hypertension is a common chronic disease, and current wearable electronic devices do not have the function of monitoring blood pressure or have poor monitoring accuracy, and thus cannot meet the blood pressure monitoring needs of users.

[0072] Based on this, the present application provides a wearable electronic device and a wristband, which can more accurately detect the pulse wave of the radial artery of a user and improve the accuracy of blood pressure monitoring.

[0073] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings.

[0074] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting on the present application. As used in the specification and the appended claims of the present application, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, such as “one or more,” unless the context clearly indicates otherwise.

[0075] Reference to "one embodiment" or "an embodiment" or "some embodiments" or "one implementation" or "an implementation" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase "in one embodiment" or "in some embodiments" or "in other embodiments" or "in still other embodiments" or other similar phrases in the specification are not necessarily all referring to the same embodiment.

[0076] Wearable electronic devices have become very common electronic products in life, among which smart watches and smart bands are the most accepted wearable devices by the public and are widely used in daily exercise and basic health parameter monitoring. Embodiments of the present application provide a wearable electronic device which can be used for blood pressure monitoring of a user, specifically by monitoring the pulse signal of the radial artery at the wrist of the user to calculate the blood pressure of the user. The wearable electronic device can include electronic devices that can be fixed on the wrist of the user, such as smart watches and smart bands. As shown in FIG. 1, embodiments of the present application provide a wearable electronic device 100, which is exemplified as a smart watch. The wearable electronic device 100 includes a main body 20 and a wristband 10, the wristband 10 is detachably connected to the main body 20, and the wristband 10 can be wrapped around the wrist of the user to fix the wearable electronic device 100 on the user's body. The main body 20 can be approximately circular, rectangular or other polygonal in shape, which is not limited by the present application. In FIG. 1, a case where the main body 20 is square is shown. It is easy to understand that in the case of the wearable electronic device 100 being a smart watch or a smart band, the main body 20 of the wearable electronic device 100 is the watch body, and the wristband 10 of the wearable electronic device 100 is the watch band. It should be understood that the wristband 10 can be one, and the two ends of the wristband 10 are detachably connected to the opposite sides of the main body 20, respectively. The wristband 10 can also be two, and the two wristbands 10 are detachably connected to the opposite sides of the main body 20, respectively, and the two wristbands 10 can be connected by buckling, magnetic attraction or the like.

[0077] In some embodiments, the main body 20 comprises a housing 201 and a display screen 202 fixedly connected and enclosing a receiving space. The display screen 202 can be used to display images, videos, etc. The display screen 202 can be circular, rectangular or other regular or irregular shape. The receiving space formed by the display screen 202 and the housing 201 can be used to accommodate various functional modules and electronic components of the wearable electronic device 100, such as circuit boards, processors, batteries, charging management modules, communication modules, sensor modules, audio modules, speakers, microphones, etc., so that the wearable electronic device 100 can realize various functions.

[0078] The wearable electronic device 100 has an inner side and an outer side when worn. When the wearable electronic device 100 is fixed to the wrist of a user, the side of the wearable electronic device 100 facing the wrist of the user can be considered as the inner side of the wearable electronic device 100, and the side of the wearable electronic device 100 facing away from the wrist of the user can be considered as the outer side of the wearable electronic device 100, which faces the external environment. Taking the main body 20 as an example, the display screen 202 of the main body 20 is located on the side of the housing 201 facing away from the wrist of the user, and the light-emitting side of the display screen 202 is the outer side of the wearable electronic device 100. The outer surface of the housing 201 is formed with a connection end for docking the wristband 10.

[0079] The wearable electronic device 100 provided by the embodiments of the present application has a blood pressure monitoring function. The wristband 10 comprises a band body 101, an air bag structure 102, and a sensor 103 integrated in the air bag structure 102. The sensor 103 is fixed to the air bag structure 102, and the sensor 103 is shown in dashed lines. When the wearable electronic device 100 is worn on the wrist of a user, the projection of the air bag structure 102 and the sensor 103 on the wrist of the user can cover at least part of the wrist of the user. The sensor 103 can be used to detect the pulse wave of the user including the radial artery and the ulnar artery. After the air bag structure 102 is inflated, the volume expands and presses the wrist of the user. The sensor 103 detects the pulse wave of the radial artery of the user and transmits the detection data to the main body 20. The processor in the main body 20 can calculate the blood pressure of the user. The blood pressure of the user includes systolic pressure and diastolic pressure, etc. When the user wears the wearable electronic device 100, the air bag structure 102 is located on the side of the band body 101 facing the user to facilitate the sensor 103 to detect the pulse wave of the user. For ease of understanding, the surface of the band body 101 for contacting the skin of the wrist of the user can be considered as a first surface, and the surface of the band body 101 facing away from the skin of the wrist of the user can be considered as a second surface. The first surface and the second surface are opposite along the thickness direction of the band body 101. It can also be considered that the first surface of the band body 101 is the inner side of the band body 101, and the second surface is the outer side of the band body 101.

[0080] As shown in the exploded view of a main body 20 in FIG. 2a, the main body 20 includes a shell 201, a display screen 202, a main board 203, an air pump 204, a connecting piece 205, and an auxiliary connecting piece 206. The shell 201 is in the shape of an open box. The display screen 202 can be fixedly buckled at the opening of the shell 201. A containing space can be formed between the display screen 202 and the shell 201. The main board 203 and the air pump 204 can be accommodated in the containing space. The outer peripheral surface of the shell 201 is formed with a second docking end surface 2011 for docking the wristband 10. When the wristband 10 is connected to the main body 20, the first docking end surface 1011 of the wristband 10 cooperates with the second docking end surface 2011 of the main body 20. The shell 201 is further formed with a second connecting portion 2012 for connecting the wristband 10. Exemplarily, the second connecting portion 2012 is a clamping groove, a recess, or a through groove. The wristband 10 can be clamped with the second connecting portion 2012 to achieve the connection between the wristband 10 and the main body 20. The number of the second connecting portion 2012 can be one, two, or more. Here, two second connecting portions 2012 are exemplified, which are arranged along the direction perpendicular to the thickness of the main body 20. The shell 201 is provided with a second air flow port 2014. Here, the second air flow port 2014 is part of the structure of the shell 201. The second air flow port 2014 is provided with an inflation channel C and an adapter 207. Exemplarily, the inflation channel C penetrates the shell 201 along the direction perpendicular to the thickness of the main body 20. The projection of the second connecting portion 2012 and the inflation channel C on the outer peripheral surface of the shell 201 falls within the area of the second docking end surface 2011. The air pump 204 has an air outlet 2041 in communication with the inflation channel C. The gas discharged from the air outlet 2041 of the air pump 204 can be output through the inflation channel C. The main board 203 is the control center of the wearable electronic device. The main board 203 can connect various components of the wearable electronic device through various interfaces and buses. The adapter 207 is used to realize electrical connection with the electrically controlled sensor 103 on the wristband 10, so that the pulse wave data of the user detected by the sensor 103 can be transmitted to the main board 203. Exemplarily, the adapter 207 can be connected with the main board 203 through the connecting piece 205. The main body 20 further includes the auxiliary connecting piece 206 for strengthening the electrical connection of the connecting piece 205. The adapter 207 can be designed in an integrated structure with the shell 201, or can be independent of the shell 201 and embedded in the shell 201. The structure of the adapter 207 can also be designed as needed to ensure waterproofness and air tightness on the basis of meeting the electrical connection scheme.

[0081] Figure 2b shows a partial structure of the main body 20, with the display screen 202 omitted. As shown in Figure 2b, the main board 203, the air pump 204, the connecting member 205, and the auxiliary connecting member 206 are installed in the housing 201. The air charging passage C of the second air flow port 2014 is not shown due to the viewing angle, and is shown in gray shade. The air outlet 2041 of the air pump 204 is connected to the air charging passage C. In the thickness direction of the main body 20, the air pump 204 at least partially overlaps the main board 203. The second air flow port 2014 is provided with an adapter 207, which is embedded in the second air flow port 2014 and can be exposed to the inner wall of the air charging passage C. Here, only a part of the structure of the adapter 207 exposed to the second air flow port 2014 is shown. It can be considered that the adapter 207 is structurally integrated with the second air flow port 2014. After the adapter 207 is embedded in the second air flow port 2014, the adapter 207 is equivalent to a structure integrated with the second air flow port 2014. In order to facilitate the electrical connection between the adapter 207 and the main board 203, the adapter 207 can be connected to the main board 203 through the auxiliary connecting member 206. Specifically, the connecting member 205 is exemplified as a flexible circuit board, which is connected between the adapter 207 and the main board 203. The auxiliary connecting member 206 is exemplified as an elastic steel sheet, which is fixed to the housing 201 by screws. The auxiliary connecting member 206 can apply a pressing force to the connecting member 205, so that the connecting member 205 can be tightly connected to the adapter 207 and the main board 203, achieving good electrical connection effect.

[0082] In some embodiments, the auxiliary connecting member 206 can be integrally formed with the housing 201, and press the connecting member 205 according to the preset position and shape, to achieve the electrical connection between the adapter 207 and the main board 203.

[0083] Correspondingly, FIG. 3a shows the structure of the wristband 10. The wristband 10 comprises a band body 101, an airbag structure 102, a sensor 103, and an electrical connection structure 104. The band body 101 has a first docking end surface 1011 for docking with the main body 20, and the end surface of the first docking end surface 1011 is configured to cooperate with the end surface of the second docking end surface 2011 of the main body 20. The band body 101 is further formed with a first connecting portion 1012 and a first airflow port 1013 for connecting the main body 20. Exemplarily, based on the structure of the two second connecting portions 2012 on the main body 20, two spaced-apart first connecting portions 1012 are exemplified here, which are hooks protruding from the end surface of the first docking end surface 1011. Each first connecting portion 1012 is configured to cooperate with the second connecting portion 2012 on the main body 20 to achieve clamping fixation, thereby achieving the connection of the wristband 10 with the main body 20. The first airflow port 1013 protrudes from the first docking end surface 1011, and when the wristband 10 is connected with the main body 20, the first airflow port 1013 can be used to cooperate with the inflation channel C of the main body 20. The airbag structure 102 is fixed to the band body 101 for contacting the first surface of the user and communicating with the first airflow port 1013. The sensor 103 can be wired to the first airflow port 1013 through the electrical connection structure 104.

[0084] FIG. 3b is a partial structure diagram of the wristband 10, showing the partial structure at the first docking end surface 1011 of the wristband 10. As shown in FIG. 3b, the first connecting portion 1012 and the first airflow port 1013 protrude from the first docking end surface 1011. Exemplarily, the first connecting portion 1012 is a hook, and two first connecting portions 1012 are arranged along the length direction of the first docking end surface 1011, which can also be considered as the width direction of the wristband 10. The first airflow port 1013 comprises a first base body 10132 and a first support 10133, and the first base body 10132 and the first support 10133 enclose a gas guide channel D, and the first support 10133 is provided with an electrical connection terminal 106. The first airflow port 1013 further comprises at least one sealing ring 10131 sleeved on the outer peripheral surface of the first base body 10132, and each sealing ring 10131 protrudes from the outer peripheral surface of the first base body 10132.

[0085] Exemplarily, the electric connection terminal 106 is fixed to the first support 10133 and exposed to the first air flow port 1013. The electric connection terminal 106 is used to connect the adapter 207 on the main body 20, and the sensor 103 can be electrically connected to the electric connection terminal 106 through the electric connection structure 104. The electric connection terminal 106 and the adapter 207 are detachably connected, so that the electric connection and disconnection can be realized during the connection and disconnection of the wristband 10 and the main body 20. The detachable connection between the electric connection terminal 106 and the adapter 207 includes but is not limited to elastic contact, plug-in, snap connection and the like. The first support 10133 can be an injection molding part. The first support 10133 has a structure surface M, and the electric connection terminal 106 protrudes from the structure surface M. In some embodiments, the structure surface M formed by the first support 10133 is a plane and is arranged obliquely relative to the extension direction of the first air flow port 1013. In the direction of the end of the first abutting end surface 1011 away from the first abutting end surface 1011 and pointing to the first air flow port 1013, the structure surface M is inclined to the direction close to the axis of the first air flow port 1013, thereby forming an inclined structure surface M on the outer surface of the first air flow port 1013. The structure surface M is not coplanar with the plane where the port of the air guide channel D is located, so that the electric connection and the air communication of the wristband 10 do not interfere with each other.

[0086] Figure 3c is an exploded view of a part of the structure of the wristband 10, showing a part of the structure at the first interface end surface 1011 of the wristband 10. As shown in Figure 3c, the band body 101 includes a main structure 10101, an end structure 10102, and a fixing member 10103. The first interface end surface 1011 of the band body 101 is formed on the main structure 10101, and the first connecting portion 1012 and the first airflow port 1013 are formed on the end structure 10102. The end structure 10102 can be combined with the main structure 10101 by integral molding, and the first connecting portion 1012 and the first airflow port 1013 protrude from the first interface end surface 1011. The fixing member 10103 is used to fix the airbag structure 102 to the end structure 10102. The airbag structure 102 includes an air nozzle 1021 and an airbag 1022, the airbag 1022 encloses an internal space for containing gas, the air nozzle 1021 is fixed to the airbag 1022 and communicates with the internal space of the airbag 1022, and the air nozzle 1021 can be used to inflate the airbag 1022 or discharge gas. The electrical connection structure 104 for connecting the sensor 103 is shown as one end penetrating the air nozzle 1021 of the airbag structure 102 into the airbag structure 102, and the other end of the electrical connection structure 104 extends out of the air nozzle 1021 to connect with the electrical connection terminal 106 fixed to the first bracket 10133. When the airbag structure 102 is fixed to the end structure 10102, the air nozzle 1021 of the airbag structure 102 is used to detachably fix the end structure 10102 and communicate with the air guide channel D of the first airflow port 1013, and when the wristband 10 is assembled, the airbag structure 102 and the band body 101 can be quickly disassembled.

[0087] Fig. 3d is a schematic diagram of a partial cross-sectional structure of the wristband 10 after being cut along the thickness direction of the air guide channel D and the wristband 10. As shown in Fig. 3d, the first air flow port 1013 partially protrudes from the first abutting end surface 1011 of the band body 101, and the air guide channel D penetrates the first air flow port 1013. The air bag 1022 of the air bag structure 102 is fixed to the inner side of the main structure 10101, i.e., the first surface side of the band body 101. The air bag 1022 encloses an air cavity Q for accommodating gas, and the air nozzle 1021 is fixed to the end head structure 10102 and is used for communication with the air guide channel D. The sensor 103 is exemplarily accommodated in the air cavity Q of the air bag 1022, and in order to improve the detection accuracy, the sensor 103 is exemplarily fixed in the form of attachment to the inner wall of the air cavity Q on the side facing the user. The electrical connection terminal 106 is at least partially exposed on the outer surface of the first air flow port 1013, one end of the electrical connection structure 104 is exemplarily extended along the air guide channel D into the air cavity Q of the air bag structure 102 and electrically connected with the sensor 103, and the other end of the electrical connection structure 104 is electrically connected with the electrical connection terminal 106. Wherein, the electrical connection structure 104 can be a flexible circuit board or a wire. It should be understood that the connection between the electrical connection terminal 106 and the electrical connection structure 104 can be that the electrical connection terminal 106 passes through the first support 10133 and is connected with the electrical connection structure 104, or the electrical connection structure 104 passes through the first support 10133 and is connected with the electrical connection terminal 106, or a conductor structure for connecting the electrical connection terminal 106 and the electrical connection structure 104 is embedded in the first support 10133, and the electrical connection terminal 106 and the electrical connection structure 104 are connected through the conductor structure.

[0088] Wherein, the number of sensors 103 can be one or multiple. When the number of sensors 103 is multiple, the multiple sensors 103 can be integrated on a substrate to form an array arrangement, and the array dimension can be one-dimensional or multi-dimensional, so as to more comprehensively and accurately monitor the pulse wave of the radial artery of the user. Wherein, the sensor 103 can select a piezoelectric sensor in the form of a diaphragm to detect the pulse wave by using piezoelectric characteristics. The specific material of the sensor 103 includes poly vinylidene fluoride (PVDF). The sensor 103 can be fixed to the air bag structure 102 by adhesion or other means to ensure reliable fixation of the sensor 103 and prevent suspension and displacement when the sensor 103 is pressed by the inflation of the air bag structure 102.

[0089] In the above embodiment, the first air flow port 1013 is part of the end structure 10102, the end structure 10102 is formed with an auxiliary channel F in communication with the air guide channel D, and the air guide channel D and the auxiliary channel F are in communication to form a zigzag-shaped channel. The air nozzle 1021 is detachably connected to the end structure 10102 in a detachable connection manner, the air nozzle 1021 is detachably connected to the end structure 10102, and the air nozzle 1021 can be aligned and communicated with the auxiliary channel F of the end structure 10102, thereby realizing communication with the air guide channel D. In order to ensure air tightness, a sealing ring or other structure is arranged at the connection between the air nozzle 1021 and the end structure 10102. Of course, the structure of the air guide channel D and the air bag structure 102 can also have other implementation manners. For example, the air bag 1022 is directly connected to the end structure 10102 by adhesion, welding or other manners and is in communication with the air guide channel D, and the structure of the air nozzle 1021 is omitted. It should be understood that the air bag 1022 needs to be inflated when inflated and shrunk when deflated, and the air bag 1022 is generally made of soft material. The air nozzle 1021 is generally made of plastic material, which can ensure a certain shape and make the air flow smoothly through the air nozzle 1021 into the air bag 1022.

[0090] Fig. 4a is a structural example of the electrical connection terminal 106, the first bracket 10133 and the adapter 207 of the main body 20 in a possible implementation of the wristband 10. As shown in Fig. 4a, the first bracket 10133 and the first base 10132 enclose the air guide channel D, or the first bracket 10133 and the first base 10132 enclose part of the air guide channel D. The first bracket 10133 has a structure surface M. Exemplarily, the structure surface M is a plane and is inclined relative to the extension direction of the first air flow port 1013. The electrical connection terminal 106 includes at least two metal electrodes 1061, exemplarily two metal electrodes 1061, which are fixed to the first bracket 10133 to be integrated on the first air flow port 1013. Each metal electrode 1061 has a contact surface m exposed to the structure surface M, and each contact surface m of each metal electrode 1061 is used to face contact with the adapter 207 to realize electrical connection. The contact surface m here is parallel to the structure surface M, and the contact surface m is inclined relative to the extension direction of the first air flow port 1013, which can be considered that the contact surface m is inclined relative to the extension direction of the air guide channel D. Each metal electrode 1061 is arranged radially along the air guide channel D and inclined to each other, and the port plane of the first air flow port 1013 away from the end of the strap body 101 and the plane of the contact surface m form an angle, which can reduce the size of the first air flow port 1013 along the thickness direction of the wristband 10, save structural space, and facilitate device miniaturization. Exemplarily, the contact surfaces m of the two metal electrodes 1061 are coplanar. The first bracket 10133 is made of insulating material, such as plastic, which can partially wrap and insulate the surface of the metal electrode 1061 except the contact surface m. Alternatively, the other surfaces of the metal electrode 1061 except the contact surface m are insulated, for example, an insulating coating is coated on these surfaces to form a protective insulating layer to protect the metal electrode 1061.

[0091] Correspondingly, the adapter 207 of the main body 20 can be selected as an elastic conductor. In one embodiment, the adapter 207 is an elastic silica gel member, specifically including an elastic insulating base 2071 and conductive particles doped in the insulating base 2071, and the conductive particles form at least two conductive channels T, each conductive channel T being used to connect the contact surface m of one metal electrode 1061 and the connecting member 205 of the main body 20. Exemplarily, the adapter 207 forms two cylindrical conductive channels T, and the two conductive channels T communicate with both ends of the insulating base 2071. In some embodiments, the resistance of the conductive channel T of the elastic silica gel member is less than 0.5Ω. The elastic insulating base 2071 can be embedded in the first air flow port 1013 in an interference fit manner, and the conductive channel T realizes waterproof sealing while conducting electricity.

[0092] In some embodiments, as shown in FIG. 4b, two metal electrodes 1061 are used to connect the contact surface m of the adapter 207 and the port of the air guide channel D to be coplanar. Exemplarily, the two metal electrodes 1061 can be located on both sides of the air guide channel D along the width of the wristband 10, without occupying the space of the air guide channel D along the thickness direction of the wristband 10. The electric connection terminal 106 in the form of the metal electrode 1061 is coplanar with the port of the air guide channel D when connecting the adapter 207, and at this time, the structure and position of the adapter 207 of the main body 20 need to be adjusted adaptively to ensure the electrical connection relationship between the adapter 207 and the electric connection terminal 106. Of course, when the number of metal electrodes 1061 increases to multiple according to the type of sensor 103, the multiple metal electrodes 1061 can be distributed at intervals around the air guide channel D.

[0093] In other embodiments, as shown in FIG. 4c, the first support 10133 is fixed in the air guide channel D of the first air flow port 1013, and the outer surface of the first support 10133 and the inner surface of the air guide channel D form a channel for air flow, which is in the form of a cylinder. Specifically, a plurality of supports or the like can be arranged between the outer wall of the first support 10133 and the inner wall of the air guide channel D, and the plurality of supports can be distributed at intervals along the circumference of the first support 10133 to separate the outer wall of the first support 10133 and the inner wall of the air guide channel D, and the gap between any two adjacent supports can be used for air flow, and the shape and distribution of the supports are considered to not affect the flow of air flow. The electric connection terminal 106 is not specifically shown as a metal electrode 1061 or other forms of structure, and only the positional relationship between the electric connection terminal 106 and the air guide channel D is shown. It can be considered that the electric connection terminal 106 for connecting the contact surface of the adapter 207 and the port of the air guide channel D can also be coplanar. Of course, the electric connection terminal 106 is coplanar with the port of the air guide channel D when connecting the adapter 207, and at this time, the structure and position of the adapter 207 of the main body 20 also need to be adjusted adaptively to ensure the electrical connection relationship between the adapter 207 and the electric connection terminal 106.

[0094] In the following embodiments, the structure of the electric connection terminal 106 and the adapter 207 shown in FIG. 4a will be taken as an example to exemplarily introduce the connection between the wristband 10 and the main body 20.

[0095] Figure 5a is a partial structure of the wristband 10 and the main body 20 connected and matched, and the shell 201 is hidden. As shown in Figure 5a, the first air flow port 1013 of the wristband 10 is connected and matched with the air pump 204 of the main body 20, and the air outlet 2041 of the air pump 204 specifically abuts the end of the first air flow port 1013 away from the first abutting end surface 1011, so that the air guide channel D formed by the first base 10132 and the first support 10133 is in communication with the air outlet 2041 of the air pump 204, and the air guide channel D is not shown here. One end of the adapter 207 abuts on the first support 10133 of the first air flow port 1013 to connect the electrical connection terminal 106. One end of the connecting piece 205 abuts on the end of the adapter 207 away from the first air flow port 1013, and the other end of the connecting piece 205 is connected to the main board 203, and the auxiliary connecting piece 206 abuts on the connecting piece 205. After being fixed to the shell 201, the auxiliary connecting piece 206 can apply a force to the connecting piece 205 to press against the main board 203, and at the same time, the auxiliary connecting piece 206 can apply a force to the adapter 207 through the connecting piece 205 to press the first air flow port 1041, so as to finally realize the electrical connection between the electronic terminal 1041 and the main board 203.

[0096] Figure 5b is a partial cross-sectional structure of the wristband 10 and the main body 20 connected and matched. As shown in Figure 5b, the first air flow port 1013 of the wristband 10 is exemplarily inserted into the inflation channel C of the main body 20, the air guide channel D of the first air flow port 1013 is connected and matched with the air outlet 2041 of the air pump 204, and the auxiliary channel F of the band body 101 can realize the communication between the air pump 204 and the air cavity Q of the air bag 1022. In some embodiments, a sealing gasket or the like structure can be arranged between the first air flow port 1013 and the air outlet 2041 to improve the air tightness. The second air flow port 2014 is a part of the shell 201, the adapter 207 is specifically embedded in the second air flow port 2014 and extends into the inflation channel C, the adapter 207 can contact the electrical connection terminal 106 integrated in the first air flow port 1013, and the main board 203 is connected through the connecting piece 205, and the auxiliary connecting piece 206 can apply pressure to the connecting piece 205 to increase the reliability of the electrical connection between the electrical connection terminal 106, the adapter 207, the connecting piece 205 and the main board 203.

[0097] The first air flow port 1013 is inclined toward the plane where the end surface of the air pump 204 is located with reference to the thickness direction of the main body 20, and the plane where the air outlet 2041 of the air pump 204 is located is parallel to the end surface of the first air flow port 1013. Correspondingly, the end surface of the first air flow port 1013 is equivalent to being able to exert a downward component force on the air outlet 2041 of the air pump 204, which is beneficial to make the cooperation between the first air flow port 1013 and the air outlet 2041 of the air pump 204 more tightly and firmly, and is beneficial to improve the air tightness. When the first air flow port 1013 extends into the air filling channel C, the inclined surface formed by the first support 10133 makes the end of the first air flow port 1013 have a structure similar to a cone, which can reduce the resistance of the first air flow port 1013 inserted into the air filling channel C, and facilitate the insertion of the first air flow port 1013 into the air filling channel C. The inclined surface formed by the first support 10133 also does not excessively contact the air filling channel C to reduce the wear on the electrical connection terminal 106, which is beneficial to improve the electrical connection reliability and service life of the electrical connection terminal 106. During the process of the first air flow port 1013 extending into the air filling channel C, the electrical connection terminal 106 contacts the adapter 207 and exerts an upward component force on the adapter 207, and finally the electrical connection terminal 106 presses the adapter 207. When the wrist strap 10 is connected to the main body 20, the adapter 207 has a certain elastic potential energy due to the compression of the structure in the direction perpendicular to the contact surface of the electrical connection terminal 106 and the adapter 207, thereby ensuring good electrical connection effect between the two. The surface connected by the electrical connection terminal 106 and the adapter 207 is not coplanar with the surface connected by the first air flow port 1013 and the air outlet 2041, which is more conducive to realizing the air tightness between the first air flow port 1013 and the air outlet 2041.

[0098] When the wearable electronic device 100 is worn on the wrist of the user, the air pump 204 can be used to inflate the air cavity Q of the air bag structure 102. After the air bag 1022 is inflated, the volume is expanded to press the wrist of the user. The sensor 103 detects the pulse wave of the user, and the pulse wave signal monitored by the sensor 103 is transmitted to the main board 203 through the electrical connection structure 104, the electrical connection terminal 106, the adapter 207, and the connecting piece 205. The main board 203 analyzes and processes the signal to determine the blood pressure value of the user.

[0099] Figure 6 is a partial structure of the air bag structure 102 and the electrical connection structure 104 of the wearable electronic device 100 provided by the embodiments of the present application. As shown in Figure 6, the sensor 103 is accommodated in the air bag 1022 of the air bag structure 102, which is not shown here. The electrical connection structure 104 for connecting the sensor 103 penetrates the air nozzle 1021 of the air bag structure 102, which can be considered as a combination of the electrical connection part and the air guide part of the wristband 10. Exemplarily, the air bag structure 102 has a cuboid shape that is adapted to the shape of the band body 101, and the air bag 1022 can be formed by connecting multiple film layers with small thickness. The material of the film layer can be thermoplastic polyurethane elastomer rubber (TPU). When the air cavity Q of the air bag 1022 is not inflated, the adjacent film layers are almost in close contact with each other, and in the schematic view with reference to the structure of the wristband 10, it is difficult to clearly show the structure of the air bag 1022. Therefore, the cooperation structure between the air bag structure 102, the sensor 103, and the electrical connection structure 104 will be exemplarily introduced by the structural diagram of the air bag structure 102.

[0100] It should be noted that in the above embodiments, the cooperation between the first air flow port 1013 of the wristband 10 and the second air flow port 2014 of the main body 20 is achieved by inserting the protruding first air flow port 1013 into the inflation channel C of the second air flow port 2014. Similarly, it can be achieved by inserting the protruding second air flow port 2014 into the air guide channel D of the first air flow port 1013. Alternatively, the first air flow port 1013 and the second air flow port 2014 of the main body can also be connected in other ways, which are not limited by the present application. In addition, the first connection part 1012 of the wristband 10 and the second connection part 2012 of the main body 20 are also fixedly connected by inserting a protruding structure into a recessed structure, and the cooperation modes of the two can be interchanged. In some embodiments, the two can also be directly connected and locked by other auxiliary structures. It should be understood that these assembly modes can be obtained by deforming the conventional assembly structure, as long as the sealing of the electrical connection and the air connection is ensured, and the exemplary description of the embodiments of the present application will not be performed.

[0101] Figure 7a is a cross-sectional view of the cooperation structure between the air bag structure 102, the sensor 103 and the electrical connection structure 104 according to an embodiment of the present application. As shown in Figure 7a, the air bag structure 102 can include a first film layer 10201 and a second film layer 10202, and the first film layer 10201 is connected along the thickness direction of the air bag 1022 and forms an air cavity Q between the first film layer 10201 and the second film layer 10202. The sensor 103 is exemplarily accommodated in the air cavity Q. It is provided that the first film layer 10201 is fixed to one side of the strap 101, and the second film layer 10202 is towards the side of the user's wrist, and the sensor 103 can be fixed to the inner wall of the second film layer 10202, so that when the user wears the wearable electronic device, the sensor 103 can be closer to the user's wrist, thereby improving the accuracy of blood pressure monitoring. One end of the electrical connection structure 104 is connected to the sensor 103, and the other end extends in the air cavity Q to the air nozzle 1021 of the air bag structure 102, and extends along the channel of the air nozzle 1021. In this embodiment, part of the electrical connection structure 104 is accommodated in the air cavity Q of the air bag 1022, and part of the electrical connection structure 104 passes through the air nozzle 1021, so that the electrical connection structure 104 can be conveniently connected to the electrical connection terminal 106 integrated in the first air flow port 1013. As can be seen from Figure 7a, when the wrist strap 10 is attached to the user's wrist, the second film layer 10202 of the air bag 1022 is in contact with the user's skin, and the sensor 103 is only separated from the user's wrist by a layer of second film layer 10202, so that the sensor 103 can accurately detect the pulse wave signal of the user's wrist.

[0102] The electric connection structure 104 can be a flexible circuit board or a coaxial line as shown in FIG. 7b. When the sensor 103 has two electric connection terminals 106, the electric connection structure 104 also has two conductive wires. When the electric connection structure 104 is in the form of a coaxial line, the electric connection structure 104 can include an inner conductor 1041 and an outer conductor 1042 arranged in layers in some embodiments. The inner conductor 1041 and the outer conductor 1042 are respectively connected to the two electrode terminals of the sensor 103. The coaxial line with the inner and outer layers can shield the inner conductor 1041 with the outer conductor 1042, thereby improving the electromagnetic shielding effect of the electric connection structure 104 and reducing the interference loss of the signal transmission of the sensor 103. It should be understood that when the electric connection structure 104 is connected to the sensor 103, the inner conductor 1041 and the outer conductor 1042 at one end of the electric connection structure 104 are separated to be respectively connected to the two electrode terminals of the sensor 103. Similarly, when the electric connection structure 104 is connected to the electric connection terminal 106, the inner conductor 1041 and the outer conductor 1042 at the other end of the electric connection structure 104 are separated to be respectively connected to the two metal electrode terminals 1061 of the electric connection terminal 106. In some embodiments, the diameter of the coaxial line is less than or equal to 0.4 mm. The diameter of the coaxial line can be 0.4 mm, 0.35 mm, 0.2 mm, etc. The radial dimension of the coaxial line can be smaller than the inner diameter of the air guide channel D, so that the coaxial line can be arranged through the air nozzle 1021 of the airbag structure 102 and the air guide channel D of the strap 101 without affecting the smooth flow of air in the air nozzle 1021 and the air guide channel D.

[0103] Figure 8a is a cross-sectional view of the cooperation structure between another airbag structure 102 and a sensor 103 and an electrical connection structure 104. As shown in Figure 8a, the airbag 1022 can include a first film layer 10201, a second film layer 10202, and an intermediate film layer 10203, which are stacked in sequence along the thickness direction of the airbag 1022, the first film layer 10201 and the intermediate film layer 10203 form a first chamber q1, the intermediate film layer 10203 and the second film layer 10202 form a second chamber q2, the intermediate film layer 10203 has a through hole k that communicates the first chamber q1 and the second chamber q2, and the first chamber q1 and the second chamber q2 can communicate through one or more through holes k to form an air cavity Q of the airbag 1022. The sensor 103 is exemplarily accommodated in the air cavity Q, and can be located in the second chamber q2 and fixed to the inner wall of the second film layer 10202. The air nozzle 1021 is fixed between the first film layer 10201 and the intermediate film layer 10203 and communicates with the first chamber q1. The electrical connection structure 104 can pass through the through hole k between the first chamber q1 and the second chamber q2, so that a part of the electrical connection structure 104 is located in the second chamber q2 to connect the sensor 103, and another part of the electrical connection structure 104 is located in the first air cavity q1 to pass through the air nozzle 1021.

[0104] In some embodiments, as shown in Figure 8b, the intermediate film layer 10203 can be provided in two layers, which are stacked between the first film layer 10201 and the second film layer 10202. Among them, the intermediate film layer 10203 close to the first film layer 10201 is connected with the first film layer 10201 and forms the first chamber q1, which can be considered that the first film layer 10201 cooperates with the intermediate film layer 10203 to form the first airbag. The intermediate film layer 10203 close to the second film layer 10202 is connected with the second film layer 10202 and forms the second chamber q2, which can be considered that the second film layer 10202 cooperates with the intermediate film layer 10203 to form the second airbag. The airbag 1022 can be considered to be formed by stacking the first airbag and the second airbag along the thickness direction of the airbag structure 102. Of course, both the two intermediate film layers 10203 have at least one through hole k, and the through holes k of the two intermediate film layers 10203 can correspond to each other to communicate to communicate the first chamber q1 and the second chamber q2.

[0105] Referring to the structures shown in Figures 8a and 8b, the airbag 1022 is equivalent to including two airbags, one of which forms the first chamber q1 close to the belt 101, and the other of which forms the second chamber q2 close to the user, and the first chamber q1 and the second chamber q2 communicate to form the air cavity Q of the airbag 1022. When the airbag 1022 is inflated, the two airbag stacking structures can more easily make the air cavity Q expand along the thickness direction of the airbag 1022, and the effect of compressing the user's wrist is better.

[0106] In some embodiments of the wearable electronic device 100 provided by the present application, the main body 20 and the wristband 10 shown in FIGS. 9a-9b and FIGS. 10a-10c are connected in a manner different from the above embodiments.

The main board 203 and the air pump 204 are accommodated in a receiving space formed after the display screen 202 is coupled to the housing 201. The housing 201 is formed with a second connecting portion 2012, a second electrical connecting port 2013, and a second air flow port 2014. The second air flow port 2014 has an inflation channel C. Exemplarily, the second connecting portion 2012, the inflation channel C of the second air flow port 2014, and the second electrical connecting port 2013 each extend through the housing 201 in a direction perpendicular to the thickness of the main body 20.

One end of the adapter 207 is connected to the main board 203, and the other end faces the second electrical connecting port 2013. The adapter 207 has an adapter surface J facing the second electrical connecting port 2013. The area of the adapter surface J can be greater than the cross-sectional area of the second electrical connecting port 2013, so that the projection of the adapter surface J on the second connecting surface 2011 can cover the second electrical connecting port 2013. The adapter surface J can be a plane, and the adapter surface J is arranged at an angle with the extension direction of the second electrical connecting port 2013. Exemplarily, the second connecting portion 2012 is a clamping slot, a recess, or a through slot. The wristband 10 can be clamped with the second connecting portion 2012 to achieve the connection between the wristband 10 and the main body 20.

As shown in FIG. 9b, the main board 203, the adapter 207, and the air pump 204 are installed in the housing 201. The inflation channel C of the second air flow port 2014 is not shown due to the viewing angle and is shown in gray shading. The air outlet 2041 of the air pump 204 is connected to the inflation channel C.

The band body 101 has a first interfacing end surface 1011 for interfacing with the second interfacing end surface 2011 of the main body 20. The band body 101 is further formed with a first connecting portion 1012 for connecting with the main body 20, a first air flow port 1013 and a first electrical connection port 1014 provided with an electrical connection terminal 106. Exemplarily, based on the structure of the two first connecting portions 1012 on the main body 20, two spaced-apart first connecting portions 1012 are exemplified here, which are exemplarily hooks protruding from the end surface of the first interfacing end surface 1011. Each first connecting portion 1012 is used to cooperate with the second connecting portion 2012 on the main body 20 to achieve clamping fixation, thereby achieving physical structural connection of the wristband 10 with the main body 20. The first air flow port 1013 protrudes from the first interfacing end surface 1011, and when the wristband 10 is connected with the main body 20, the first air flow port 1013 is exemplarily used to plug-fit with the inflation channel C of the main body 20. The airbag structure 102 is fixed to the band body 101 for contacting the inner side of the user and communicating with the air guide channel D of the first air flow port 1013. One end of the electrical connection structure 104 is connected with the sensor 103, and the other end is connected with the electrical connection terminal 106. The first electrical connection port 1014 protrudes from the first interfacing end surface 1011 for interfacing with the second electrical connection port 2013 of the main body 20, and the electrical connection terminal 106 is used to be able to extend into the main body 20 and elastically connect with the adapter 207.

[0110] Fig. 10b is a schematic diagram of a partial structure of the wristband 10, which specifically shows the structure at the first interfacing end surface 1011 of the wristband 10. As shown in Fig. 10b, the first connecting portion 1012, the first airflow port 1013, and the first electrical connection port 1014 protrude from the first interfacing end surface 1011. Exemplarily, the first connecting portion 1012 is in the form of a hook, and two first connecting portions 1012 are arranged along the length direction of the first interfacing end surface 1011, which can also be considered as the width direction of the wristband 10. The first airflow port 1013 includes a first base body 10132 and a sealing ring 10131 in the form of a cylinder to form an air guide channel D, and the outer peripheral surface of the first base body 10132 is sleeved with at least one sealing ring 10131, and each sealing ring 10131 protrudes from the outer peripheral surface of the first base body 10132.

The second support 10143 can be made of an insulating material such as plastic, which provides partial insulation protection for the electrical connection terminal 106. Exemplarily, the electrical connection terminal 106 includes at least two elastic conductors (pogo pin) 1062 arranged in parallel with the first airflow port 1013, and here four elastic conductors 1062 are arranged in sequence along the width direction of the wristband 10. The elastic conductor 1062 can be any one of a probe with a built-in spring, a spring sheet, a spring, a conductive soft rubber, or a combination of at least two of them, and the elastic conductor 1062 can realize elastic electrical connection.

[0111] Figure 10c is an exploded view of a part of the structure of the wristband 10, showing a part of the structure at the first interfacing end surface 1011 of the wristband 10. As shown in Figure 10c, the band body 101 comprises a main structure 10101, an end structure 10102, and a fixing member 10103. The first interfacing end surface 1011 of the band body 101 is formed on the main structure 10101, the first connecting portion 1012 and the first airflow port 1013 are formed on the end structure 10102, and the second base 10142 of the first electrical connecting port 1014 is formed on the fixing member 10103. The second base 10142 is annular, the second support 10143 of the first electrical connecting port 1014 is fixed to the second base 10142, and the electrical connecting terminal 106 is fixed to the second support 10143. The sealing ring 10141 is exemplarily sleeved on the outer circumferential surface of the second support 10143. The end structure 10102 and the main structure 10101 can be combined together by way of integral molding, and the first connecting portion 1012 and the first airflow port 1013 are protruded from the first interfacing end surface 1011. The fixing member 10103 is used to fix the air bag structure 102 to the end structure 10102. The air bag structure 102 exemplarily comprises an air nozzle 1021 and an air bag 1022, the air nozzle 1021 is used to be in sealed connection with the first airflow port 1013, and the air bag 1022 has an internal space in communication with the air nozzle 1021. The sensor 103 is exemplarily arranged on the side of the air bag structure 102 away from the band body 101, and the sensor 103 is located outside the air bag structure 102. In order to protect the sensor 103, the wristband 10 further comprises a protective film layer 105, the protective film layer 105 is arranged on the side of the air bag structure 102 away from the band body 101 and covers the sensor 103, and the sensor 103 is equivalent to being located between the air bag 1022 and the protective film layer 105. The electrical connecting structure 104 is used to connect the sensor 103 and the electrical connecting terminal 106. Since the sensor 103 is externally located outside the air bag 1022, the electrical connecting structure 104 is routed outside the air bag 1022, and the protective film layer 105 can cover the electrical connecting structure 104 located outside the air bag 1022 to protect the electrical connecting structure 104.

[0112] Figure 10d is a schematic diagram of a partial cross-sectional structure of the wristband 10 along the thickness direction of the elastic conductor 1062 and the wristband 10. As shown in Figure 10d, the airbag structure 102 is fixed to the inner side of the band body 101, the airbag 1022 of the airbag structure 102 has an air cavity Q, and the sensor 103 is exemplarily accommodated outside the airbag 1022 of the airbag structure 102 and specifically located on the side facing the user. The protective film layer 105 is attached to the side of the airbag 1022 facing the user along the thickness direction of the airbag structure 102 and covers the sensor 103 and the electrical connection structure 104. The protective film layer 105 and the airbag 1022 can be fixed by heat sealing. Exemplarily, the electrical connection structure 104 is arranged between the airbag 1022 and the protective film layer 105, one end of the electrical connection structure 104 extends along the outer surface of the airbag 1022 to connect with the sensor 103, and the other end is connected with the electrical connection terminal 106. The electrical connection structure 104 can be a flexible circuit board or a wire. The second bracket 10143 is embedded and fixed to the second base body 10142, and the second bracket 10143 circumferentially wraps the electrical connection terminal 106, so that the electrical connection terminal 106 can be fixed to the first electrical connection port 1014. The outer circumferential surface of the second bracket 10143 is provided with a circumferentially surrounding sealing ring 10141. One end of the second bracket 10143 facing the airbag structure 102 can be heat sealed and connected with the protective film layer 105, and the electrical connection terminal 106 passes through the protective film layer 105 to contact the electrical connection structure 104 to realize electrical connection. In the above wristband 10, the electrical connection part and the air communication part are isolated.

[0113] Figure 11a is a partial structure of the wristband 10 connected and matched with the main body 20, where the shell 201 is hidden. As shown in Figure 11a, the first air flow port 1013 of the wristband 10 is connected with the air outlet 2041 of the air pump 204 of the main body 20, and the air pump 204 can deliver gas to the airbag structure 102 of the wristband 10 through the first air flow port 1013. One end of the adapter 207 facing the first electrical connection port 1014 elastically abuts against the electrical connection terminal 106, and the electrical connection of the electrical connection terminal 106 and the main board 203 can be realized. The adapter 207 here can be selected as a flexible circuit board.

[0114] Figure 11b is a cross-sectional view of the electrical connection part of the wristband 10 and the main body 20. As shown in Figure 11b, the adapter 207 is located in the shell 201 and opposite the first electrical connection port 1014. The first electrical connection port 1014 can be mated with the second electrical connection port 2013, and the second base 10142 extends into the second electrical connection port 2013, and the sealing ring 10141 on the outer periphery of the second support 10143 is sealingly engaged with the inner wall of the second electrical connection port 2013. The electrical connection terminal 106 can pass through the second electrical connection port 2013 and elastically abut the adapter 207, so that the sensor 103 can be electrically connected to the main board 203. The electrical connection structure 104 is exemplarily arranged between the air bag 1022 and the protective film layer 105, and one end of each electrical connection terminal 106 passes through the protective film layer 105 and is welded to the electrical connection structure 104 located between the air bag 1022 and the protective film layer 105. The shell 201 and the adapter surface J of the adapter 207 can also be provided with a sealing soft rubber 208 to achieve waterproof sealing, and the sealing soft rubber 208 can circumferentially surround the second electrical connection port 2013 to ensure the waterproof sealing effect.

[0115] Figure 11c is a cross-sectional view of the gas communication part of the wristband 10 and the main body 20. As shown in Figure 11c, the first gas flow port 1013 of the wristband 10 is inserted into the inflation channel C of the main body 20, and the gas guide channel D of the first gas flow port 1013 is connected to the gas outlet 2041 of the air pump 204 through the inflation channel C. In some embodiments, a sealing gasket can be provided between the first gas flow port 1013 and the gas outlet 2041 to improve the air tightness. In this example, the end surface of the first gas flow port 1013 is parallel to the plane where the gas outlet 2041 is located and parallel to the thickness direction of the main body 20. Since the electrical connection part and the gas communication part are separated, the air tightness between the first gas flow port 1013 and the gas outlet 2041 is easier to ensure. Exemplarily, the first base 10132 of the first gas flow port 1013 is circumferentially interference-fitted with the inner wall of the inflation channel C, and the end surface of the gas outlet 2041 is sealingly engaged with the end surface of the inflation channel C of the shell 201. The inflation channel C can participate in the flow of gas, and the air tightness between the first gas flow port 1013 and the gas outlet 2041 can be ensured.

[0116] In some embodiments, the first air flow port 1013 can be directly sealed and docked with the air outlet 2041 of the air pump 204 through the inflation channel C, which is used to dock the first air flow port 1013 and does not participate in the circulation of air flow. In this case, the second electrical connection port 2013 and the second air flow port 2014 can be arranged adjacent to each other in a direction perpendicular to the thickness of the main body 20, and the inflation channel C of the second electrical connection port 2013 and the slot-shaped second air flow port 2014 are connected to form a large-aperture communication hole. The inflation channel C and the second air flow port 2014 can be considered as part of the communication hole. The projection of the air outlet 2041 of the air pump 204 and the adapter surface J of the adapter 207 on the shell 201 can at least partially fall within the radial range of the communication hole. When the main body 20 is connected with the wristband 10, the first air flow port 1013 can pass through the communication hole to dock with the air outlet 2041 of the air pump 204 to achieve air communication, and the first electrical connection port 1014 can pass through the communication hole to connect with the adapter surface J of the adapter 207 to achieve electrical connection. In this structure, the air inlet and outlet of the air bag 1022 of the wearable electronic device 100 and the electrical connection of the sensor 103 are independent of each other.

[0117] FIG. 12 is a partial structure of the air bag structure 102, the electrical connection structure 104, and the protective film layer 105 of the wearable electronic device 100 provided by the embodiments of the present application. As shown in FIG. 12, the electrical connection structure 104 for connecting the sensor 103 and the air nozzle 1021 of the air bag structure 102 are arranged in a width direction of the air bag structure 102, and the electrical connection structure 104 is clamped between the air bag 1022 and the protective film layer 105. The air inlet and outlet of the air bag 1022 of the wearable electronic device 100 and the electrical connection of the sensor 103 are independent of each other, and the air tightness of the first air flow port 1013 and the air outlet 2041 of the air pump 204 is easier to guarantee.

[0118] When the sensor 103 is arranged outside the air cavity Q of the air bag 1022, the electrical connection structure 104 and the air cavity Q are independent of each other, and FIGS. 13a and 13b illustrate the cross-sectional structure of the air bag structure 102, the sensor 103, and the electrical connection structure 104.

[0119] Figure 13a is a cross-sectional view of the cooperation structure between the airbag structure 102, the sensor 103 and the electrical connection structure 104 according to an embodiment of the present application. As shown in Figure 13a, the airbag structure 102 can include a first film layer 10201 and a second film layer 10202, and the first film layer 10201 is connected along the thickness direction of the airbag 1022 and forms an air cavity Q between the first film layer 10201 and the second film layer 10202. The sensor 103 is exemplarily accommodated in the air cavity Q and is specifically located outside the airbag 1022. It is provided that the first film layer 10201 is fixed to one side of the wristband 101, and the second film layer 10202 is towards the side of the user's wrist, and the sensor 103 can be fixed to the side of the second film layer 10202 away from the first film layer 10201. One end of the electrical connection structure 104 is connected with the sensor 103 and extends along the outer surface of the second film layer 10202 to the end of the wristband 101 for connecting the main body 20, and the protective film layer 105 is attached to the side of the second film layer 10202 away from the first film layer 10201 and extends to the end of the wristband 101 for connecting the main body 20 in a manner of covering the sensor 103 and the electrical connection structure 104, and the electrical connection structure 104 is clamped between the airbag 1022 and the protective film layer 105. When the user wears the wearable electronic device, the sensor 103 can be closer to the user's wrist, improving the accuracy of blood pressure monitoring. Since the air nozzle 1021 of the airbag structure 102 and the end of the electrical connection structure 104 away from the sensor 103 are arranged in the width direction of the wristband 10, the cross-section does not pass through the air nozzle 1021, and the air nozzle 1021 here is not shown in the cross-sectional view. It should be understood that the air nozzle 1021 is in communication with the air cavity Q of the airbag 1022.

[0120] Figure 13b is a schematic cross-sectional view of the cooperation structure between another airbag structure 102 and a sensor 103 and an electrical connection structure 104. As shown in Figure 13b, the airbag 1022 can include a first film layer 10201, a second film layer 10202, and an intermediate film layer 10203, which are stacked in order along the thickness direction of the airbag 1022, a first cavity q1 is formed between the first film layer 10201 and the intermediate film layer 10203, a second cavity q2 is formed between the intermediate film layer 10203 and the second film layer 10202, the intermediate film layer 10203 has a through hole k that communicates the first cavity q1 and the second cavity q2, and the first cavity q1 and the second cavity q2 can communicate through one or more through holes k to form an air cavity Q of the airbag 1022. The sensor 103 is exemplarily accommodated outside the air cavity Q and can be fixed to the side of the second film layer 10202 away from the first film layer 10201. The air nozzle 1021 is in communication with the first cavity q1. One end of the electrical connection structure 104 is connected to the sensor 103 and extends along the outer surface of the second film layer 10202 to the end of the air nozzle 1021 of the airbag 1022, and the protective film layer 105 is attached to the side of the second film layer 10202 away from the first film layer 10201 in a manner of covering the sensor 103 and the electrical connection structure 104. The airbag structure 102 is equivalent to including two airbags, one of which forms a first cavity q1 close to the belt 101, and the other of which forms a second cavity q2 close to the user, and the first cavity q1 and the second cavity q2 communicate to form an air cavity Q of the airbag 1022. When the airbag 1022 is inflated, the two airbag superposition structures can more easily make the air cavity Q expand along the thickness direction of the airbag 1022, and the effect of compressing the user's wrist is better. Exemplarily, a part of the protective film layer 105 is fixed to the second film layer 10202, and a part is fixed to the intermediate film layer 10203.
