The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application.

It should be understood that the terms "length", "inner", "outer", "axial", "radial", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0029] Combine the following Figure 1-Figure 6 An electronic device according to an embodiment of the present application is described.

[0030] The present application embodiment provides an electronic device, such as Figure 1 and Figure 2As shown, it includes a housing 10, a driving member 20, a telescopic member 30, a detection element 40 and a main board 50. The housing 10 is provided with a through hole 11, the main board 50 and the telescopic member 30 are both installed in the housing 10, the detection element 40 and the driving member 20 are respectively connected to the main board 50, the detection element 40 is installed on the telescopic member 30, and the driving member 20 is connected to the telescopic member 30. Under the action of the driving member 20, the telescopic member 30 expands or contracts to drive the detection element 40 to move axially along the through hole 11.

[0031] Among them, the telescopic member 30 itself is telescopic and can expand or contract. For example, the driving member 20 is an air pump, and the telescopic member 30 is an airbag. The air pump inflates the airbag to expand the airbag, driving the detection element 40 to move out of the housing 10 along the axial direction of the through hole 11; the air pump evacuates the airbag to shrink the airbag, driving the detection element 40 to move into the housing 10 along the axial direction of the through hole 11. The detection element 40 includes one or more of a light detector, a barometric blood pressure monitor, and a pulse sensor. The detection element 40 needs to keep in contact with the user's skin during the detection process. Taking a smart watch as an example, in scenes such as exercise and walking, the wrist swings back and forth, and the smart watch and the skin at the wrist will be temporarily separated, resulting in the inability of the detection element 40 to accurately detect human body data. The main board 50 is the control center of the electronic device. The driving member 20 and the detection element 40 are respectively connected to the main board 50, the main board 50 controls the movement of the driving member 20, and the detection information of the detection element 40 is transmitted to the main board 50. Taking a mobile phone as an example, during detection, it may be shaken accidentally and lose contact with the skin. At this time, the telescopic member 30 can be adjusted to fit the skin, thereby reducing external interference and improving detection accuracy.

[0032] Among them, the electronic device disclosed in the embodiments of the present application can be a smart watch, a sports bracelet, a mobile phone, a tablet computer, etc. Of course, the electronic device disclosed in the embodiments of the present application can also be other types of electronic devices, and the embodiments of the present application do not specifically limit the specific types of electronic devices.

[0033] In the electronic device provided in the embodiment of the present application, the driving member 20 drives the telescopic member 30 to expand or contract, thereby driving the detection element 40 installed on the telescopic member 30 to move axially along the through hole 11, and under the control of the main board 50, the detection element 40 is ensured to fit the skin to ensure the accuracy of the detection.

[0034] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the electronic device also includes a pressure sensor 60, which is used to detect the pressure between the detection element 40 and the user's skin. The pressure sensor 60 is connected to the main board 50. The main board 50 is used to control the driving member 20 to drive the telescopic member 30 to expand when the pressure is less than a preset value, and to control the driving member 20 to drive the telescopic member 30 to contract when the pressure is greater than a preset value.

[0035] The size of the preset value is determined according to the type of the detection element 40. When the pressure value between the detection element 40 and the user's skin is the preset value, the detection element 40 can detect data relatively accurately. The pressure value detected by the pressure sensor 60 is transmitted to the main board 50, and after analysis and processing by the main board 50, the driving member 20 is controlled to perform corresponding operations to ensure that the pressure between the detection element 40 and the user's skin is stable at the preset value.

[0036] It should be noted that the number of the detection elements 40 can be multiple, and correspondingly, the driving member 20 and the telescopic member 30 are correspondingly provided. In the case where the number of the detection elements 40 is multiple, each detection element 40 is configured with a pressure sensor 60, and the corresponding driving member 20 is controlled by the detection data of the corresponding pressure sensor 60, so as to accurately control each detection element 40, ensuring that each detection element 40 can be accurately detected.

[0037] Optionally, the mainboard 50 performs the above control only in the sports mode to avoid frequent driving of the driving member 20 due to changes in the pressure value, thereby saving electric energy and extending the available time of the fully charged battery of the electronic device.

[0038] In the electronic device provided in the embodiment of the present application, the mainboard 50 controls the expansion and contraction of the telescopic member 30 according to the pressure, thereby ensuring accurate detection of the detection element 40.

[0039] In some embodiments of the present application, Figure 3-Figure 6 As shown, the electronic device also includes an outer frame 70 , the telescopic member 30 and the detection element 40 are both installed in the outer frame 70 , the first side of the telescopic member 30 is fixedly connected to the outer frame 70 , and the second side of the telescopic member 30 is fixedly connected to the detection element 40 .

[0040] like Figure 3-Figure 6 As shown, the outer frame 70 is a square frame with one end open, and the outer frame 70 is fixedly mounted on the housing 10. The driving member 20 is mounted outside the outer frame 70, and the telescopic member 30 is mounted inside the outer frame 70. When the driving member 20 is an air pump and the telescopic member 30 is an air bag, the air pump is connected to the air bag through an air pipe, and the air pipe is inserted into the outer frame 70. Optionally, the air pipe is a bellows or a hose, which can move with the expansion and contraction of the air bag. When the driving member 20 is an excitation coil and the telescopic member 30 is a flexible bag filled with magnetostrictive material, the excitation coil can be mounted inside or outside the outer frame 70. When the excitation coil is mounted outside, there is no direct connection between it and the flexible bag, and there is no need to open a mounting hole on the outer frame 70.

[0041] Specifically, the first side of the telescopic member 30 is bonded and fixed to the bottom of the outer frame 70, and the second side of the telescopic member 30 is bonded to the detection element 40. Since the detection element 40 is connected to the main board 50, a wire hole is provided on the outer frame 70, and the detection element 40 is connected to the main board 50 through a flexible circuit board 51 passing through the wire hole. The flexible circuit board 51 is flexible, so that the detection element 40 can move axially along the through hole 11 while maintaining effective communication with the main board 50.

[0042] In some specific embodiments of the present application, a limiting structure 71 is provided on the outer frame 70 , and the limiting structure 71 is used to limit the maximum length of the detection element 40 extending out of the housing 10 .

[0043] like Figure 1 and Figure 2 As shown, the pressure sensor 60 is arranged outside the outer frame 70. When the pressure sensor 60 detects that the pressure value is less than the preset value, the driving member 20 drives the telescopic member 30 to expand, so that the detection element 40 moves out of the housing 10. The limit position of its movement is when the circuit board of the detection element 40 abuts against the limiting structure 71, or when the protrusion on the mounting structure of the detection element 40 abuts against the limiting structure 71, thereby limiting the maximum length of the detection element 40 extending out of the housing 10.

[0044] Specifically, Figure 3-Figure 6 As shown, the limiting structure 71 is arranged at the open end of the outer frame 70, and the limiting structure 71 is a protrusion, which is arranged around the circumference of the open end of the outer frame 70. When the detection element 40 extends out of the housing 10, the limiting structure 71 can limit the extension length of the detection element 40, and when the detection element 40 retracts into the housing 10, the limiting structure 71 can block the gap between the detection element 40 and the inner wall of the outer frame 70. Of course, only two limiting structures 71 can be arranged on the outer frame 70, which can also play a limiting role.

[0045] In some embodiments of the present application, Figures 3 to 6 As shown, the electronic device further includes a padding block 80 , a side of the padding block 80 facing away from the through hole 11 is connected to the telescopic member 30 , and the detection element 40 is mounted on the padding block 80 .

[0046] like Figures 3 to 6 As shown, the padding block 80 is a square box with a thicker bottom, and the detection element 40 is installed in the box. The padding block 80 can increase the adjustable length of the airbag, ensuring that the detection element 40 can extend out of the housing 10, avoiding the difficulty in ensuring the telescopic distance of the detection element 40 due to the limited telescopic ability of the telescopic member 30 itself. In addition, the padding block 80 can also be a plate with a certain thickness, as long as it can play a role in adjusting the extension amount of the detection element 40 in the axial direction of the through hole 11.

[0047] In some specific embodiments of the present application, the detection element 40 is a light detector, the raising block 80 includes a bottom plate 81 and a light-shielding side wall 82 , the light-shielding side wall 82 is fixedly installed on the circumference of the bottom plate 81 , and the light detector is installed on the bottom plate 81 .

[0048] When users exercise, electronic devices such as smart watches will be temporarily separated from the user's skin. To prevent external interference light from entering the light detector, such as Figure 3 and Figure 4 As shown, the pad block 80 includes a bottom plate 81 for mounting the optical detector and a light shielding side wall 82 surrounding the bottom plate 81. The light shielding side wall 82 effectively prevents external interference light from entering the optical detector, ensuring that the detection light of the optical detector is directly emitted by the light reflected by the user.

[0049] Optionally, the electronic device further includes a transparent cover plate 83, such as Figures 3 to 6 As shown, the transparent cover 83 is fixedly mounted on the light-shielding side wall 82, thereby sealing the detection element 40 in the cavity formed by the transparent cover 83, the light-shielding side wall 82 and the bottom plate 81. The transparent cover 83 contacts the user's skin to provide a flat contact surface, thereby preventing the end of the light-shielding side wall 82 from contacting the skin and causing discomfort to the user.

[0050] In some specific embodiments of the present application, the electronic device further includes a light emitting element 90 , which is installed in the housing 10 and connected to the mainboard 50 . The light detector includes multiple light detectors, which are arranged at intervals along the circumference of the light emitting element 90 .

[0051] The light emitting element 90 is an LED lamp, and the mainboard 50 controls the switch of the LED lamp. For example, the number of light detectors is four, and the four light detectors are evenly distributed along the circumference of the light emitting element 90. Of course, the number of light detectors can also be two, three, etc., which is not specifically limited in the embodiment of the present application.

[0052] In some optional embodiments of the present application, such as Figure 3 As shown, the driving member 20 is an air pump, the telescopic member 30 is an air bag, and the air pump is connected to the air bag.

[0053] When the pressure value detected by the pressure sensor 60 is less than the preset value, Figure 3 As shown, the airbag is inflated by the air pump, pushing the detection element 40 to move outside the housing 10, ensuring that the pressure between the detection element 40 and the user's skin reaches a preset value. When the pressure value detected by the pressure sensor 60 is greater than the preset value, the skin is prevented from being squeezed to affect the detection accuracy. Figure 4 As shown, the airbag is exhausted by the air pump, driving the detection element 40 to move into the housing 10 .

[0054] In some further optional embodiments, the driving member 20 is an excitation coil, and the telescopic member 30 includes a flexible bag filled with magnetostrictive material.

[0055] The flexible bag is a rubber bag or a plastic bag. Magnetostrictive material is a material that can convert electromagnetic energy into mechanical energy. Under the action of the alternating magnetic field generated by the excitation coil, the magnetic flux density of the magnetostrictive material changes, thereby achieving the expansion and contraction of the flexible bag. Specifically, the main board 50 controls the on-off charge or current of the excitation coil to adjust the magnetic field strength. Figure 5 As shown in FIG. 1 , the magnetostrictive material contracts, driving the detection element 40 to retract. Figure 6 As shown, the magnetostrictive material expands, driving the detection element 40 to expand.
