[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0029] The blood pressure detection method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0030] The blood pressure detection method provided in an embodiment of the present application is applied to an electronic device, which is a scroll screen electronic device including a shell assembly, a scroll screen and a PPG sensor, and the PPG sensor is arranged on a frame of the shell assembly distributed along the unfolding direction of the scroll screen.

[0031] Optionally, the shell assembly includes a first shell and a second shell, the first shell and the second shell are slidably connected, one end of the scroll screen is connected to the first shell, and the other end of the scroll screen is connected to the second shell. Driven by the scroll motor, the scroll screen can be extended and retracted, and can be switched between an expanded state and a retracted state.

[0032] Among them, during the unfolding process of the scroll screen, the first shell and / or the second shell can be driven to move by the scroll motor, and then the scroll screen can be unfolded; the scroll screen can also be driven to unfold by the scroll motor, and then the first shell and the second shell can be driven to move in opposite directions, thereby realizing the unfolding process of the scroll screen.

[0033] The PPG sensor is used to detect the pulse wave signal in the user's arterial capillaries, and the detected pulse wave signal can be used to calculate the corresponding systolic and diastolic pressure results based on the corresponding algorithm, thereby calculating the corresponding blood pressure test results.

[0034] In the present application, during the blood pressure detection process, the user can hold the position of the shell assembly where the PPG sensor is located; moreover, in order to facilitate the user to quickly locate the PPG sensor provided on the shell assembly, a reminder mark can also be displayed at the position of the shell assembly where the PPG sensor is provided, such as displaying words such as "PPG", so as to achieve the purpose of reminding the user.

[0035] See also Figure 1 , Figure 1 is a flow chart of the blood pressure detection method provided in the embodiment of the present application. Figure 1As shown, the method comprises the following steps:

[0036] Step 101: When a target object holds the area where the PPG sensor is located, a target torque is outputted by a scroll motor of the electronic device, and the target torque is used to drive the scroll screen to unfold.

[0037] In this step, the target torque can be understood as a driving force that can drive the scroll screen to unfold, that is, the target torque is greater than the static friction of the scroll screen and can drive the scroll screen to enter the unfolded state.

[0038] Step 102: When the unfolded length of the scroll screen is maintained within a target length range, a pulse wave signal detected by the PPG sensor is obtained.

[0039] In this step, when the unfolded length of the scroll screen is maintained within the target length range, it can be understood that the target torque output by the scroll motor and the holding force of the target object have reached a balance, so that the unfolded length of the scroll screen is maintained within a length range. That is, by detecting whether the unfolded length of the scroll screen is maintained within the target length range, the relationship between the target torque and the holding force of the target object can be judged, and then the holding force of the user can be determined.

[0040] During the blood pressure detection process, the target object is required to maintain the pressing force within the pressure range required for blood pressure detection in order to improve the accuracy of blood pressure detection; therefore, the pressing force of the target object can be adjusted by controlling the size of the target torque so that the target object maintains the pressing force within the pressure range required for blood pressure detection, thereby achieving the purpose of improving the accuracy of blood pressure detection.

[0041] It can be understood that the target torque in the present application is used to maintain the pressing force of the target object within the pressure range required for blood pressure detection.

[0042] Specifically, it is possible to determine whether the target torque output by the scroll motor and the holding force of the target object (i.e., the pressing force of the target object on the PPG sensor) are balanced by judging whether the unfolded length of the scroll screen is maintained within the target length range; and when it is determined that the unfolded length of the scroll screen is maintained within the target length range, it is determined that the target torque output by the scroll motor and the holding force of the target object are balanced, i.e., the pressing force of the target object on the PPG sensor is within the pressure range required for blood pressure detection, thereby achieving the purpose of improving the accuracy of blood pressure detection.

[0043] Step 103: Generate a blood pressure detection result of the target object based on the pulse wave signal.

[0044] In this step, the blood pressure detection result includes a systolic pressure result and a diastolic pressure result, and the systolic pressure result and the diastolic pressure result can be calculated by fitting a virtual envelope curve based on the pulse wave signal.

[0045] In this way, by utilizing the characteristics of the scroll screen electronic device itself, the user's grip force can be maintained within the pressure range required for blood pressure detection based on the unfolding tension of the scroll screen of the scroll screen electronic device, thereby achieving the purpose of improving blood pressure detection accuracy.

[0046] Moreover, compared with existing electronic devices, by adding a pressure detection sensor to detect the user's pressing force, the layout of electronic device components can be simplified.

[0047] Among them, since the pressure required for blood pressure detection is a range, the target torque for different gears can be set, and the detection results corresponding to different gears can be obtained; then a virtual envelope curve is fitted based on the detection results of different gears, and the systolic pressure result and diastolic pressure result are finally obtained through the envelope curve, thereby achieving the purpose of improving the accuracy of blood pressure detection.

[0048] During the blood pressure detection process, the PPG sensor can collect pulse wave signals throughout the entire process, but in the process of generating the detection results, only the pulse wave signals that meet the conditions are extracted to achieve the purpose of improving the blood pressure detection results.

[0049] like Figure 2 As shown, an embodiment of the present application also provides a block diagram of an electronic device, which includes a control module 21, a scroll screen 22, a motor drive module 23, a scroll motor 24, a scroll 25 and a scroll distance sensor 26.

[0050] The control module 21 is electrically connected to the scroll screen 22 , the motor driving module 23 and the scroll distance sensor 26 , respectively; the motor driving module 23 is electrically connected to the scroll motor 24 .

[0051] The reel motor 24 is drivingly connected to the reel 25 , and the reel distance sensor 26 is disposed on the reel 25 .

[0052] The scroll distance sensor 26 is used to detect the unfolded length of the scroll screen 22 . Specifically, the unfolded length of the scroll screen 22 can be calculated by detecting the distance between the PPG sensor and the scroll 25 .

[0053] The scroll motor 24 is used to drive the scroll 25 to expand or retract, so that the scroll screen switches between an expanded state and a retracted state.

[0054] In some embodiments, the reel distance sensor 26 can form a closed-loop control with the reel screen 22 through the control module 21, so that the detection result of the reel distance sensor 26 can be displayed in real time through the reel screen 22.

[0055] Optionally, when the unfolded length of the scroll screen is maintained within a target length interval, acquiring the pulse wave signal detected by the PPG sensor includes:

[0056] When the unfolded length of the scroll screen is maintained in the target length interval, and the duration for which the unfolded length of the scroll screen is maintained in the target length interval exceeds a first preset time, the pulse wave signal detected by the PPG sensor in a time period corresponding to the first preset time is obtained.

[0057] In this embodiment, whether the target torque output by the scroll motor and the holding force of the target object are balanced is determined by judging the duration for which the unfolded length of the scroll screen is maintained in the target length range. When the unfolded length of the scroll screen is maintained in the target length range for a first preset time (for example, 10 seconds), it is determined that the target torque output by the scroll motor and the holding force of the target object are balanced, thereby improving the accuracy of the pulse wave signal detected by the PPG sensor, thereby achieving the purpose of improving the blood pressure detection results.

[0058] Optionally, after the target torque is output by the scroll motor of the electronic device, while the unfolded length of the scroll screen is maintained within the target length range, and before the pulse wave signal detected by the PPG sensor is acquired, the method further includes:

[0059] Detecting a change in the unfolded length of the scroll screen;

[0060] When the change in the unfolded length meets a preset condition, a prompt message is output, where the prompt message is used to remind the target object to adjust the gripping force and maintain the unfolded length of the scroll screen within a target length range.

[0061] In this embodiment, by detecting the change in the unfolded length of the scroll screen, it can be determined whether the unfolded length of the scroll screen is maintained within the target length range, and then it can be determined whether the target torque output by the scroll motor and the holding force of the target object are balanced.

[0062] In some implementations, Figure 2 The scroll distance sensor shown detects the change in the unfolded length of the scroll screen.

[0063] Among them, when the change in the unfolded length of the scroll screen meets the preset conditions, it can be understood that the unfolded length of the scroll screen is not maintained within the target length range, that is, the holding force of the target object is too large or too small relative to the target torque.

[0064] Specifically, when the change in the unfolded length of the scroll screen indicates that the unfolded length of the scroll screen is greater than the maximum length of the target length interval, the target object is instructed through a prompt message to increase the holding force, and the unfolded length of the scroll screen is maintained within the target length interval, that is, the scroll screen is kept from extending or retracting; correspondingly, when the change in the unfolded length of the scroll screen indicates that the unfolded length of the scroll screen is less than the minimum length of the target length interval, the target object is instructed through a prompt message to reduce the holding force, and the unfolded length of the scroll screen is maintained within the target length interval, that is, the scroll screen is kept from extending or retracting.

[0065] In addition, when the change in the unfolded length of the scroll screen indicates that the unfolded length of the scroll screen is maintained within the target length range, the target object is instructed to maintain the grip through prompt information and keep the scroll screen from retracting.

[0066] The prompt information may be output in the form of voice playback to instruct the user to perform corresponding operations.

[0067] Optionally, the method further comprises:

[0068] Displaying blood pressure detection information on the scroll screen;

[0069] The blood pressure detection information includes at least one of the following:

[0070] A schematic diagram of a curve of the target torque and the gripping force of the target object;

[0071] A schematic diagram of a countdown for the target object to maintain grip force;

[0072] Schematic diagram of holding operation;

[0073] The prompt information.

[0074] In this embodiment, by displaying blood pressure detection information in real time, especially displaying curve diagrams of target torque and target object's grip force, countdown diagrams of target object's grip force maintenance, grip operation diagrams and prompt information, it is possible to facilitate the target object to adjust the blood pressure detection operation in time, thereby improving the user's blood pressure detection experience.

[0075] In some embodiments, the detection duration can be set to 10 seconds, that is, the duration for the user to maintain grip force can be set to 10 seconds, and a countdown diagram for the target object to maintain grip force can be displayed on the scroll screen so that the user can maintain grip force, thereby achieving the purpose of improving the accuracy of the detection results.

[0076] like Figure 3a As shown, a curve diagram 31 of the target torque and the holding force of the target object can be displayed on the display interface of the scroll screen; Figure 3bAs shown, a holding operation diagram 32 and prompt information 33 can also be displayed on the display interface of the scroll screen.

[0077] The blood pressure detection method provided in the embodiment of the present application outputs a target torque through the scroll motor of the electronic device when the target object holds the area where the PPG sensor is located, and the target torque is used to drive the scroll screen to unfold; when the unfolded length of the scroll screen is maintained within the target length range, the pulse wave signal detected by the PPG sensor is obtained; and the blood pressure detection result of the target object is generated based on the pulse wave signal. In this way, the characteristics of the scroll screen electronic device itself are utilized so that the user's holding force is maintained within the pressure range required for blood pressure detection based on the unfolding tension of the scroll screen of the scroll screen electronic device, thereby achieving the purpose of improving the accuracy of blood pressure detection.
