The material of the middle frame 11 may be stainless steel, aluminum alloy, titanium alloy, PC (Polycarbonate), PA (Polyamide), or the like. The measurement module 153 is a PPG (photoplethysmography) module, and includes a light emitter 153a and a light receiver 153b, where the light emitter 153a is used for emitting infrared light and the light receiver 153b is used for receiving infrared light.
As shown in fig. 4 and 5, the wall of the middle frame 11 is provided with a window 11b penetrating through the inner and outer surfaces thereof, and it should be noted that, in the embodiment of the present application, the inner and outer surfaces are both based on the inner cavity of the middle frame 11, and the side close to the inner cavity is the inner side and the side far away from the inner cavity is the outer side. The measuring module 153 is mounted inside the window 11b and located inside the middle frame 11, and the window 11b is provided with a light-transmitting portion 13, an outer surface of the light-transmitting portion 13 may be flush with an outer surface of the middle frame 11 to obtain a relatively flat outer surface, and of course, the outer surface of the light-transmitting portion 13 may be protruded or recessed relative to the outer surface of the middle frame 11. Other function keys can be arranged on the wall of the middle frame 11, and the function keys and the light-permeable part 11 are arranged in a protruding mode, so that the identification operation can be facilitated. As shown in fig. 2, the wall of the middle frame 11 is a side wall of the smart watch 1, and for the electronic device provided with the display screen 12, the light-transmitting portion 11 and the function keys are arranged on the side wall, which is beneficial to ensuring the area of the display screen 12 and facilitating operation.
Referring to fig. 4, the light-transmitting portion 13 and the measuring module 153 are located at corresponding positions, and are located at window positions, so that the infrared light emitted by the light emitter 153a in the measuring module 153 can pass through the light-transmitting portion 13 to the outside of the light-transmitting portion 13, and the infrared light passing through the light-transmitting portion 13 can be received by the light receiver 153b from the outside.
As will be further appreciated with reference to fig. 7, fig. 7 is a schematic diagram of the acquisition of finger information by the electronic device of fig. 1.
When the tail end of the finger touches the light-transmitting part 13 at the position of the window 11b, the infrared light of the light emitter 153a can pass through the light-transmitting part 13 to reach the subcutaneous vascular tissue of the finger, and then the infrared light diffusely reflected by the blood is received by the light receiver 153b, because the content of the oxygen-carrying hemoglobin and the content of the reduced hemoglobin in the blood change during the respiration of the human body, the absorption coefficient of the blood to the infrared light also changes, and the intensity of the reflected infrared light is different, a pulse wave curve which changes with the fluctuation of the respiration motion can be obtained according to the intensity change of the received infrared light, and then the blood pressure related parameters can be identified and obtained according to the pulse curve modeling, so as to finally realize the measurement of the blood pressure, and of course, other physiological parameters, such as pulse, blood oxygen concentration and the like, can also be obtained.
The electronic equipment in the embodiment of the application acquires the blood flow signals at the tail end of the finger, the blood flow signals at the position have less interference than parts such as a wrist and the like, the measurement precision is more accurate, and the medical grade can be achieved; moreover, the light-transmitting part 13 is arranged on the electronic device, and only a finger needs to be pressed on the light-transmitting part 13, so that the measurement is simple, and when the electronic device is a wearable device such as the smart watch 1 in the graph 1, the measurement can be carried out anytime and anywhere, and the measurement is convenient.
It can be seen that, based on the principle, the light-transmitting portion 13 is disposed on the wall of the middle frame 11, and is used for emitting and injecting infrared light, the light-transmitting portion 13 in the embodiment of the present disclosure is an integrated structure made of a light-transmitting material, the light-transmitting material is mainly a transparent material, such as a whole piece of glass, a whole piece of crystal, a whole piece of sapphire, a whole piece of PC, or a whole piece of PMMA (polymethyl methacrylate, also called as acrylic or organic glass), and the like, the light-transmitting portion 13 is not required to be completely transparent as long as infrared light can pass through, and in order to ensure that the required infrared light is received, the transmittance of the light-transmitting portion 13 to the infrared light may be greater than or equal to 80%, and further controlled to be greater than or equal to 85%.
It should be noted that the light-transmitting portion 13 in the embodiment of the present application includes the first light-transmitting portion 131 and the second light-transmitting portion 132, and the separation structure 19 is provided between the first light-transmitting portion 131 and the second light-transmitting portion 132, the infrared light emitted by the light emitter 153a can pass through the first light-transmitting portion 131, and the light receiver 153b is used for receiving the infrared light passing through the second light-transmitting portion 132. With such an arrangement, since the first light-transmitting portion 131 and the second light-transmitting portion 132 are separated by the separating structure 19, the separating structure 19 can prevent the infrared rays from passing through, or weaken the infrared rays, or change the angle of the infrared rays, so that the infrared rays are difficult to reach the second light-transmitting portion 132 from the first light-transmitting portion 131, and also difficult to reach the first light-transmitting portion 131 from the second light-transmitting portion 132, thereby reducing or even avoiding crosstalk between the emitted infrared rays and the incident infrared rays, and thus improving the accuracy of measurement.
Referring to fig. 8 and 9, fig. 8 is an enlarged view of the positions of the light-transmitting portion 13 and the measuring module 153 in fig. 3; fig. 9 is a schematic view of the light-transmitting portion 13 in fig. 8.
As shown in fig. 9, the light-transmitting portion 13 may be directly processed with a groove 13a, the notch of the groove 13a faces the measuring module 153, and the groove 13a may form the partition structure 19. The groove 13a is provided, the position of the groove 13a is hollowed, when infrared light enters the groove 13a from the first light transmission part 131 or the second light transmission part 132, the groove 13a can weaken light compared with the light transmission part 13, and the angle of the light can be changed, so that the crosstalk of the emitted and incident light can be reduced in a simple manner. In fig. 9, the groove 13a is a sink groove, and has a notch on only one side, and the groove does not penetrate through the inner and outer surfaces of the light-transmitting portion. The notch 13a faces the measuring module 153, and the notch 13a does not penetrate through the outer surface of the measuring module 153, so that the integrity of the outer surface of the light-transmitting part 13 can be maintained, and external impurities can be prevented from entering the inner cavity of the middle frame 11. Of course, the groove may also be a through groove, the through groove penetrates through the inner and outer surfaces of the light-transmitting portion 13, that is, the two sides of the groove are both provided with notches, and the first light-transmitting portion 131 and the second light-transmitting portion 132 can be separated similarly, so as to achieve the same purpose of preventing crosstalk as the groove 13a of the sink groove structure.
In the embodiment of the present application, the light-transmitting portion 13 is an integrated structure, which has an advantage of being easily assembled with the window 11b, and the first light-transmitting portion 131 and the second light-transmitting portion 132 are separated by the separating structure 19, but the first light-transmitting portion 131 and the second light-transmitting portion 132 are still connected to each other through other portions of the light-transmitting portion 13. As shown in fig. 9, the notch of the groove 13a faces the inner surface of the light-transmitting portion 13, and the portion between the bottom wall of the groove 13a and the outer surface of the light-transmitting portion 13, the first light-transmitting portion 131, and the second light-transmitting portion 132 are still connected to each other to form an integral structure. Even if the partition structure 19 is a through groove, the portions of the light transmission portions 13 corresponding to both ends of the through groove are connected to the first light transmission portion 131 and the second light transmission portion 132 to form an integrated structure.

The spacer 18 may be filled in the groove 13a of the light transmission portion 13, and for example, rubber may be injected in a fluid state into the groove 13a of the light transmission portion 13 to be filled and fixed in the groove 13a of the light transmission portion 13. Of course, the spacer 18 may be made of other materials than rubber, such as plastic, metal, etc., as long as it is different from the light transmission portion 13, and this is not particularly limited in the embodiment of the present application. At this time, as described above, when the through groove is provided, the spacer can be inserted into the through groove as well.
