Specifically, the rotation directions of the first body 1 and the second body 2 are not limited, and the technical effect to be achieved in the application can be achieved by the relative shooting of the screen of the first body 1 and the screen of the second body 2 or the relative setting of the backboard of the first body 1 and the backboard of the second body 2.
The heart rate detection device 3 is used for detecting the heart rate of a user, and the heart rate detection device 3 is movably arranged in the main body; the heart rate detection device 3 is arranged to be movable and is convenient for a user to use, when the mobile phone is in a folded state, and when the user's finger stretches into the space between the first main body 1 and the second main body 2, the heart rate detection device 3 can be moved to a position opposite to the user's finger to detect the heart rate of the user.
In the first state of the body, the first body 1 and the second body 2 are in the same plane; taking a folding screen mobile phone as an example, the first state is a state that the mobile phone is unfolded and two screens are shared.
In the second state, the second main body 2 is covered on the first main body 1, and the detection range of the heart rate detection device 3 is between the first main body 1 and the second main body 2; for example, a folding screen phone, the second state is when the phone is folded together. At this moment, the detection range of the heart rate detection device 3 is between the first main body 1 and the second main body 2, and the user stretches fingers into the space between the first main body 1 and the second main body 2 at this moment, and light is not easy to enter the space between the first main body 1 and the second main body 2 due to the fact that the heart rate detection device is in a folded state, the brightness is low, a darker detection area is formed, crosstalk of the heart rate detection device 3 in the detection process is avoided, and the heart rate detection precision is improved.

The first detection device 31 and the second detection device 32 in the heart rate sensor in the prior art are prevented from being arranged on the same side, and crosstalk caused by reflection of light of the cover plate is utilized, so that measurement is more accurate. The first detection device 31 and the second detection device 32 which are oppositely arranged are controlled by the processing unit to displace and reach the region where the finger is positioned, so that more accurate measurement of the heart rate of the user is realized.
In yet another embodiment of the present application, the designated area on the opposite side of the first body 1 and the second body 2 is subjected to high light transmittance treatment. For example, in the second state, the back plates of the first body 1 and the second body 2 are disposed opposite to each other, the first high light transmission region and the second high light transmission region are disposed on the back plates of the first body 1 and the second body 2, the first detection device 31 is disposed in the first high light transmission region, and the second detection device 32 is disposed in the second high light transmission region.

The first armature 3122 drives the infrared emitting end 311 and the first distance sensor 3123 to squeeze the first elastic member 3124, and the first elastic member 3124 is deformed by squeezing, and meanwhile, the first elastic member 3124 can generate a pushing force opposite to the repulsive force, so that the infrared emitting end 311 moves slowly on the first sliding rail 3126, and reaches a position corresponding to the finger more precisely. Meanwhile, after the current on the first electromagnet 3121 disappears, the elastic restoring force of the first elastic member 3124 is matched with the first fixing plate 3125, so that the first driving mechanism 312 and the infrared emitting end 311 can be reset to the initial positions, which is convenient for the next heart rate measurement.
Along the first direction of the second main body 2, the second driving mechanism 322 sequentially includes a second electromagnet 3221, a second armature 3222, a second distance sensor 3223, a second elastic member 3224, a second fixing plate 3225, and a second sliding rail 3226 laid under the second electromagnet 3221, the second armature 3222, the second distance sensor 3223, and the second elastic member 3224, wherein the second electromagnet 3221 is fixedly arranged, the infrared emitting end 311 is fixed between the armature and the second distance sensor 3223, the relative magnetic poles of the second electromagnet 3221 and the second armature 3222 are the same after the second electromagnet 3222 is electrified, and the second armature 3222, the infrared emitting end 311, the second distance sensor 3223, and the second elastic member 3224 are linked; by energizing second electromagnet 3221, the magnetism on second electromagnet 3221 is reversed from that of second armature 3222, and a repulsive force is generated to urge second armature 3222. The second armature 3222 drives the infrared receiving end 321 and the second distance sensor 3223 to squeeze the second elastic element 3224, the second elastic element 3224 is deformed in a squeezing mode, and meanwhile the second elastic element 3224 can push force opposite to repulsive force, so that the infrared receiving end 321 moves slowly on the second sliding rail 3226, and the infrared receiving end reaches a position corresponding to a finger more accurately. Meanwhile, after the current on the second electromagnet 3221 disappears, the second driving mechanism 322 and the infrared receiving end 321 can be reset to the initial positions through the cooperation of the elastic restoring force of the second elastic piece 3224 and the second fixing plate 3225, so that the next heart rate measurement is facilitated.
Specifically, the first elastic member 3124 and the second elastic member 3224 may be springs, and when the first electromagnet 3121 and the second electromagnet 3221 are not energized, the first spring and the second spring are in an unstressed initial state, and at this time, the first spring and the second spring also have no force acting on the first fixing plate 3125 and the second fixing plate 3225. The first sliding rail 3126 can play a role in guiding the first armature 3122, the infrared receiving end 321 and the first distance sensor 3123, the second sliding rail 3226 can play a role in guiding the second armature 3222, the infrared receiving end 321 and the second distance sensor 3223, and inaccuracy of measurement results caused by offset generated by the infrared transmitting end 311 and the infrared receiving end 321 during measurement is avoided.

When the main body is in the second state, for example, the second direction is from the top of the mobile phone to the bottom of the mobile phone or from the bottom of the mobile phone to the top of the mobile phone, and the first direction is from the left side of the mobile phone to the right side of the mobile phone or from the right side to the left side of the mobile phone. At this time, since the infrared transmitting end 311 and the infrared receiving end 321 are respectively penetrating through the structures of the top and bottom of the first body 1 and the second body 2, only the infrared transmitting end 311 and the infrared receiving end 321 need to be controlled to displace in the horizontal direction, and accurate measurement of heart rate can be achieved no matter where the finger of the user is placed between the first body 1 and the second body 2.
Alternatively, as shown in fig. 1 and 2, the image capturing device is a 3D structured light camera or a TOF camera. Taking the main part as an example in the second state, the 3D structure light camera or the TOF camera can realize the overall monitoring between the first main part 1 and the second main part 2, even if the camera device is arranged at the top of the main part, if the finger of the user is positioned at the bottom of the main part, the position of the finger of the user can still be accurately positioned, and the heart rate measurement precision is ensured.
