The intelligent watch with the blood pressure measuring function is a functional watch which is convenient for users to know blood pressure data and master health conditions, the intelligent watch mainly adopts two technologies of oscillography blood pressure measurement and photoplethysmography blood pressure measurement, wherein the oscillography blood pressure measurement technology is closer to the traditional blood pressure measuring principle of a medical blood pressure monitor, and the accuracy is higher. Consequently in order to realize more accurate blood pressure test function, can add the air pump on the wrist-watch main part of intelligence wrist-watch to set up the gasbag with the gaseous phase intercommunication, aerify for the gasbag through the air pump, come more accurate measurement blood pressure through the pressure variation that detects the gasbag after aerifing. However, the air pump and the air bag are mainly arranged on one side of the watch main body, which not only increases the thickness and weight of the watch main body, but also makes the structure of the watch main body more complicated.

In order to reduce the thickness of the watch body of the intelligent watch and optimize the structure of the watch body, the air pump can be arranged on the watchband. However, in this structure, since the thickness of the whole assembly provided with the air pump is thick and the watchband is thin, the difference in thickness between the connection part of the assembly provided with the air pump and the watchband is large, which affects the wearing and use of the user. For example, in a typical use scene that a user wears a smart watch to work at a desk, the wrist of the user wearing the smart watch is placed on the support table, and the thickness of the joint of the air pump assembly and the watch band varies greatly, so that the outer surface of the joint of the air pump assembly and the watch band of the smart watch can easily collide with the support table, and the user feels a bad feeling (or feels bad feeling against the wrist), which affects the wearing experience of the user. In addition, the thickness variation difference of the connection part of the air pump assembly and the watchband is large, and appearance of the intelligent watch is also influenced.

Based on the analysis to above-mentioned technical problem, this application embodiment provides a watchband device and is equipped with intelligent wrist-watch of this kind of watchband device, and it can realize the natural transition of air pump subassembly and watchband junction, improves wearing of user and uses experience.

The embodiment of the application provides an intelligent watch, has the blood pressure detection function, and as shown in fig. 1, fig. 1 is a schematic structural diagram of the intelligent watch in the embodiment of the application. The smart watch includes a watch body 1 and a band device 2 connected to the watch body 1.

Wherein, wrist-watch main part 1 is the table body of the intelligent wrist-watch of band-pass call function, can be equipped with mainboard and battery isotructure in the inside of wrist-watch main part 1, can be equipped with the display screen of being connected with mainboard and battery electricity at the surface of wrist-watch main part 1. In addition, this wrist-watch main part 1 can also be equipped with the part that camera module, bluetooth module, various sensors, WIFI chip, discernment module etc. are connected with the mainboard electricity. The sensors include a distance sensor, a gravity sensor, a temperature sensor, a pressure sensor 213, a heart rate sensor, and the like. The identification module comprises a fingerprint identification module, a facial identification module and the like. Through the structure, the watch body 1 has the functions of communication, information receiving and sending, positioning, photographing, video recording, music playing, running recording, heart rate monitoring and the like besides the function of blood pressure detection.

In addition to the above functions, the smart watch is provided with the air pump assembly 21 and the air bag 3 on the side of the band device 2 to realize the blood pressure detection function. The following describes the belt device 2.

Referring to fig. 2 to 4, fig. 2 is a schematic structural view of a band unit according to an embodiment of the present application;

FIG. 3 is a front view of FIG. 2; fig. 4 is an exploded view of the watch band assembly of the present embodiment. The band unit 2 includes an air pump assembly 21 and a band 22 attached to both ends of the air pump assembly 21. The air pump assembly 21 includes an air pump housing 211 and an air pump 212 installed inside the air pump housing 211, the air pump housing 211 has a storage section 211a and installation sections 211b located at two ends of the storage section 211a, the storage section 211a is used for installing the air pump 212, and the installation sections 211b are used for connecting the watch band 22. The thickness of the receiving section 211a is greater than that of the mounting section 211b, and the outer surface 211b1 of the mounting section extends obliquely in a direction away from the receiving section 211a toward a direction close to the inner surface 211b2 of the mounting section, so that the thickness of the mounting section 211b is gradually reduced in a direction away from the receiving section 211 a. Wherein, the outer surface 211b1 of the mounting section refers to a side of the mounting section 211b away from the wrist of the user (i.e. the lower surface of the mounting section 211b in fig. 3), and the inner surface 211b2 of the mounting section refers to a side of the mounting section 211b close to the wrist of the user (i.e. the lower surface of the mounting section 211b in fig. 3).

In fig. 3, the areas of the receiving segment 211a and the mounting segment 211b are schematically divided by a vertical dotted line, which is not a structure of the band device 2 in order to more clearly illustrate the areas where the receiving segment 211a and the mounting segment 211b are located.

In addition, the outer surface 211b1 of the mounting segment extends obliquely in a direction away from the receiving segment 211a toward a direction close to the inner surface 211b2 of the mounting segment, taking the mounting segment 211b located on the left side of the receiving segment 211a in fig. 3 as an example, it means that the lower surface of the mounting segment 211b extends obliquely in a direction close to the upper surface of the mounting segment 211b, and the obliquely extending direction extends obliquely from right to left, that is, extends from the receiving segment 211a toward the band 22, so that the thickness of the mounting segment 211b is gradually reduced from right to left, and the thickness of the connection part of the mounting segment 211b and the band 22 is gradually reduced, thereby achieving a natural transition between the two.

In addition, the thickness of the attachment section 211b is referred to the thickness direction of the band 22.

In the embodiment of the present application, the air pump housing 211 is provided with two different functional sections, namely, a receiving section 211a for receiving and mounting the air pump 212 and a mounting section 211b for connecting and assembling with the band 22, and the mounting section 211b is designed to be gradually thinned. Like this, because the thickness of installation section 211b is towards keeping away from and accomodating section 211a, the direction that is close to watchband 22 thins gradually, so at the junction of installation section 211b and watchband 22, the thickness of installation section 211b thins gradually to roughly the same with watchband 22 thickness, thereby realize that the connection transition between installation section 211b of air pump subassembly 21 and the watchband 22 is comparatively level and smooth nature, can improve user's the comfort of wearing, avoided because of installation section 211b and watchband 22 junction thickness gradual change great and lead to the user to wear the smart watch and appear pressing against the thing and feel scheduling problem. In addition, since the air pump case 211 is designed such that the middle storage section 211a is thicker and the mounting sections 211b on both sides are thinner, the air pump case can satisfy both the requirement of smooth natural transition at the joint between the mounting section 211b and the band 22 and the requirement of space for the storage section 211a to store and mount the air pump 212.

As an alternative embodiment, the outer surface 211b1 of the mounting section is a cambered surface, and the bending curvature of the outer surface 211b1 of the mounting section is larger than that of the inner surface 211b2 of the mounting section, so that the thickness of the mounting section 211b is gradually reduced in a direction away from the receiving section 211 a.

Further, the outer surface 211b1 of the mounting segment is in arc transition connection with the outer surface of the receiving segment 211a, and the outer surface 211b1 of the mounting segment is also in arc transition connection with the outer surface of the adjacent band 22. Where the outer surface of the band 22 refers to the side of the band 22 facing away from the wrist of the user. Because in the watchband device 2 use, the surface of watchband 22 is often used for contacting with the holding surface, for example the user wears the intelligent wrist-watch that has watchband device 2 and lies down a table work hour watchband 22's surface often with the table surface contact, so the surface 211b1 of above-mentioned installation section adopts cambered surface transitional coupling design with the surface of accomodating section 211a, the surface of watchband 22, is convenient for the user to carry out "change wrist" operation, further improves the user and wears and use experience.

As another alternative, the outer surface 211b1 of the mounting section is a slope, and the slope of the outer surface 211b1 of the mounting section is greater than the slope of the inner surface 211b2 of the mounting section, so that the thickness of the mounting section 211b is gradually reduced in a direction away from the receiving section 211 a.

In the present embodiment, the air pump 212 has a flat structure. The flat air pump 212 has a thinner thickness, and the requirement on the thickness of the storage section 211a is lower, so that the thickness of the storage section 211a can be thinner, the overall structure of the storage section 211a and the installation section 211b can be designed to be thinner, the overall thickness of the watch band device 2 is reduced, the watch band device 2 is thinner, and the wearing comfort of the watch band device is further improved. In addition, the air pump 212 is a piezoelectric pump, and the piezoelectric pump can control the air pump 212 to be turned on or turned off in an electric control mode, so that the control difficulty of the air pump 212 is reduced, and the automation degree of the air pump is improved.

In addition, the embodiment of the present application also optimizes the size of the air pump assembly 21.
