In view of the above problems, an embodiment of the present invention provides a body pressure collecting and adjusting device, which includes a sensing portion, a main control portion, an adjusting portion and a supporting portion, wherein the sensing portion is used for detecting pressure information of a person lying on a mattress, the main control portion is used for inputting, storing and identifying the pressure information, and the adjusting portion adjusts the height of the mattress to a most comfortable state according to the information identified by the main control portion.

Preferably, the sensing part adopts a dot matrix pressure sensor to convert pressure data of a person lying on a bed into analog electric signals, the analog electric signals are filtered and amplified, the analog electric signals are converted into digital signals and transmitted to the main control part, the data of the pressure detection unit of the main control part are analyzed, the regulating part is controlled to act according to a specified algorithm, and the regulating part is connected with the main control part and used for acting according to instructions of the main control part.

The information acquisition and adjustment device of the invention needs to input the selection of age, sex, height, weight and body type and the pressure or pressure distribution generated under the body when different sleeping postures are lying and sleeping in a comfortable state; establishing a body model and a sleep pressure-bearing model for the user according to the basic information and the sleep information of the user; and identifying the person on the bed and the sleeping posture of the person.

In another aspect, the present invention further provides an adjusting method for the above body pressure collecting and adjusting device, which can perform automatic adjustment, and includes the following steps: acquiring basic information of a user, wherein the information can comprise: the age, gender, height, weight, and body type of the user, where the commonly used body types may be classified as the following 5: h type, A type, Y type, X type, O type; in addition, the sleep information of the user can be acquired, the sleep information comprises the pressure or pressure distribution generated under the comfortable state when the user lies and sleeps in different sleeping postures, and the sleeping postures comprise supine, left-side, right-side and prone postures; establishing a body model and a sleep pressure-bearing model for the user according to the basic information and the sleep information of the user; identifying the person on the bed and the sleeping posture of the person; if the person in the bed is a known user who has already built a physical model and a sleep compression model, it is adjusted to a comfortable state for the known user for the current sleeping posture.

The idea of the automatic adjustment method proposed according to this aspect of the invention is that: on the basis of the automatic identification and adjustment functions of the body pressure acquisition and adjustment device with intelligent identification and adjustment or the intelligent bed, higher identification accuracy and better adjustment effect are achieved through the application of a large amount of various data, particularly the participation of a large amount of data related to the individuation of each user in the automatic adjustment of the bed, so that the sleep quality and the sleep health of people can be more effectively helped and improved, and the user friendliness in the use of the bed can be further improved.

Advantageously, for further more sophisticated personal related data of the user, the basic information of the user may further include: shoulder width, head width, spine length, chest circumference, waist circumference, hip circumference, etc. Generally, the above-mentioned body production can be provided directly by the user or obtained by measurement.

Advantageously, the sleep information in other sleeping positions common to the user may be used in addition to the supine, left side, right side and prone positions, which may include sleeping positions of the user at a variety of different body inclination angles, including 45 ° and 135 °. The method has the advantage that the richness of the data used according to the method and the recognition accuracy can be further improved. Advantageously, therefore, data of the user's hands, feet in different placement positions, etc. can also be considered.

Advantageously, the sleep preference of the user is also acquired as the basic information of the user. According to the present invention, these sleep preferences may include the following preference data that the user likes: for example, pillows prefer a height that can be classified, for example, as high (above 12cm), medium (8cm-12cm), and low (below 8 cm). The sleep preferences may also include: pillows prefer softness (soft, medium, hard), shoulders prefer softness (soft, medium, hard), waist prefer softness (soft, medium, hard), and buttocks prefer softness (soft, medium, hard), and so on.

Advantageously, the condition of the user is also obtained as basic information of the user. These conditions involving automatic adjustment of the bed may include, for example, conditions at various sites such as: neck, e.g., cervical spondylosis, etc.; shoulders such as scapulohumeral periarthritis (left scapulohumeral periarthritis, right scapulohumeral periarthritis) and the like; thoracic rib parts such as costalgia (left costalgia, right costalgia) and the like; lumbar, such as lumbar disc herniation and the like; buttocks, such as hip arthritis, sacral osteoarthritis, and the like; and general spine, such as ankylosing spondylitis, scoliosis, kyphosis, and the like. Since in theory the way the mattress is adjusted will naturally be different for a user without the above-mentioned condition and for a user with one or more of the above-mentioned different conditions.

It is also advantageous that the body pressure collecting and adjusting means take this as a higher priority when the user has the relevant condition mentioned above, etc. For example, patients with cervical spondylosis sleep with physiological flexion of the neck and shoulder regions more important than other factors to be considered for adjustment. That is, when this adjustment requirement conflicts with other adjustment requirements, such as when making adjustments (e.g., maintaining reasonable shoulder pressure requires that the magnitude of the adjustment for that position of the mattress does not coincide with the magnitude of the adjustment for that position required to maintain physiological flexion), the user's adjustment requirement for disease will be adjusted over the other requirements.

Advantageously, the step of identifying the person and their sleeping posture comprises: and identifying whether people are on the bed, the number of people, whether people lie normally and respective sleeping postures. These identifications are fully enabled by the above described automatic adjustment bed and method.

Furthermore, according to a further aspect of the invention, a program product is proposed, wherein the automatic adjustment method proposed according to the above aspect is implemented when the program product is executed on a computer or a smart device. The program product can advantageously be designed as an App program in a smartphone, a Personal Digital Assistant (PDA) or as a program product in a remote control for the adjustment bed.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1 shows a schematic flow diagram of an automatic adjustment method 200 for a body pressure collecting and adjusting device according to the invention. The auto-tuning method 200 may include the steps of:

acquiring basic information 201 of a user, wherein the information can comprise: an age, gender, height, weight, and body type selection of the user;

acquiring sleep information 202 of the user, wherein the sleep information comprises pressure or pressure distribution generated under the comfortable state when the user lies and sleeps in different sleeping postures, and the sleeping postures comprise supine, left-side lying, right-side lying and prone posture;

establishing a body model and a sleep pressure bearing model 203 for the user according to the basic information and the sleep information of the user;

identifying 204 the person in the bed and his sleeping posture;

if the person in the bed is a known user who has already built a physical model and a sleep compression model, it is adjusted to a comfortable state for the current sleeping posture 205 for the known user.

The automatic bed adjusting method can be used for calling stored programs and really realizing automatic adjustment.

The above process is illustrated below with reference to a specific example.

In this embodiment, the automatic adjustment method 200 is described by taking the body pressure collecting and adjusting apparatus according to fig. 2 as an example. As shown in fig. 2, the body pressure collecting and adjusting device comprises a sensing part, a main control part and an adjusting part, wherein the sensing part is connected with the main control part, the main control part is connected with the adjusting part, the adjusting part is partitioned according to a specified number, each partition corresponds to a part of a human body, and the sensing part comprises: a detection unit such as a pressure sensor for detecting the pressure of the human body part transmitted by each section of the adjustment part, an adjustment unit such as a motor for adjusting the mechanical adjustment part, and a control chip as a controller. The control part can make corresponding judgment and decision according to the detected pressure of each subarea, and outputs a corresponding control command to control the adjusting unit to make appropriate action so as to drive the adjusting part to act to adjust the height of the specified subarea area, so that the pressure of each subarea is adjusted through the adjustment of the height of the subarea area.

Specifically, the pressure data of a person lying on a bed is converted into analog electric signals by a dot matrix pressure sensor, the analog electric signals are filtered and amplified and are converted into digital signals to be transmitted to the main control part, the data of the pressure detection unit of the main control part are analyzed, the action of the adjusting part is controlled according to a specified algorithm, and the adjusting part is connected with the main control part and used for acting according to instructions of the main control part.

For example, according to the bed shown in fig. 2, the static muscle model and the spine model can be established by acquiring basic information of a human body, the number of people, the weight of the people and whether the people normally lie can be identified by setting the partition pressure detection unit to detect the partition pressure, and the sleeping posture can be accurately identified by means of a corresponding algorithm.

According to this embodiment the adjustment part can be understood as a mechanical adjustment mechanism for the bed that can be adjusted in height up and down by power of a linear mechanism, e.g. an electric motor.

According to the present embodiment, the supporting portion may be understood as including an elastic mattress body and a supporting bracket, the elastic mattress body may be provided with latex, sponge and independent springs from top to bottom, and the divisional pressure detection unit is provided in an intermediate layer between the supporting bracket and the independent springs. Specifically, the support bracket may be formed by connecting a predetermined number of separate support plates and angle steels through a connected spring, the elastic mattress body is embedded in the support bracket, and each separate support plate or angle steel supports a predetermined partition pressure detection unit.

In addition, the body pressure collecting and adjusting device is also provided with a remote controller and a memory. The memory can comprise a data memory for storing data and parameters and a program memory which is designed to store a control program. The memory can be installed on the electric control part and can also be installed in a remote controller. The automatic adjustment method 200 for a bed according to the above may be realized when a control program for automatic adjustment of a bed included in the control program for a bed is executed on, for example, a control chip.

In particular, the body pressure collecting and regulating device is arranged in a mattress, preferably an intelligent mattress.

Specifically, for example, if after purchasing the bed and installing the bed in the user's home, basic information of all users of the bed can be first input through the setup and input interface on the remote controller, if the user of the bed is a couple, the input information may include: age, sex, height, weight and body type of the couple, wherein the commonly used body types can be classified into the following 5 types: h type, A type, Y type, X type and O type.

In addition to the above information, the information may include physical parameters of the couple, such as shoulder width, head width, spinal length, chest circumference, waist circumference, and hip circumference. These parameters can be obtained by self-measurement and can also be entered via the setting and input interface of the remote control.

Of course, since the above parameters need to be obtained by actual measurement, if the user does not measure the above parameters, the user can directly input the fitted jacket size or shirt size, trousers size (usually using the foot size as the size), etc. instead of the above parameters, such as when the user of the bed is a single person or an old person or a person with a sick or defective body, which is a very troublesome task. Of course, if there are conditions, the above data can be completely inputted, that is, not only the physical parameters of shoulder width, head width, spine length, chest circumference, waist circumference, hip circumference, etc. but also the size of the standard clothes fitted by the user, so that the adjustment is more delicate and careful due to the more reference parameters.

In addition, after the personal information is inputted through the remote controller, the sleep information of both couples is inputted, and here, the sleep information may include the pressure or the pressure distribution generated to the body of both couples in a comfortable state when they lie down in different sleeping postures, which may include supine, left-side, right-side and prone. In addition, the data of different body inclination angles can be included, such as the inclination angles of 45 degrees and 135 degrees, the data of different placement positions of hands and feet, and the like.

Specifically, according to the bed provided by the invention, the acquisition of the sleep information can be realized by switching to a sleep information acquisition mode through a remote controller, and then the couples lie on the bed in the sleeping postures respectively and independently, and keep the sleeping postures for 5 seconds respectively, so that the bed can automatically record each sleep information and remind the user to store the sleep information in the information storage area of a specific user person.

After all the data acquisition of the couple is completed, the relevant data is stored in the information group for a certain person in the form of data group so as to be used for the following modeling of body model and sleep pressure bearing model.

If the user, i.e. the exemplary couple or both confirms that the data collection is completed through the remote controller, the operation and control system of the bed can automatically establish an accurate body model and a sleep pressure-bearing model, for example, half of the difference between the shoulder width and the head width, i.e. the height of the head and neck kept straight when lying on the side (the height of the pillow can be correspondingly set or the height of the bed surface can be adjusted to maintain the height value when lying on the side). After body parameters such as the length of the spine, the shoulder width, the chest circumference, the waist circumference, the hip circumference and the like and pressure distribution data of the user in each sleeping posture are obtained, the body contour and the spine can be modeled. Then, the bed can be switched to the use mode by the user's operation of the remote controller. In the use mode the bed first has to identify the person in the bed and his sleeping position, e.g. which one or both of the couple and his wife are sleeping in the bed. This is fully achievable according to the bed and method described above and will not be described in detail here. Then, according to the real-time body pressure distribution monitored by the bed sensing system, comparing the original models of the users stored in the system, the offset of different positions of the spine and the original positions can be analyzed in real time, and therefore adjustment can be carried out according to the offset.

Here, if the person on the bed is a known user who has already built a physical model and a sleep pressure-bearing model, the person is adjusted and controlled for the model that the known user has already built to adjust to a comfortable state for the current sleeping posture. If a guest comes home and does not have the process of inputting personal information and establishing a body model and a sleep pressure-bearing model, the guest can be actively reminded to finish the process or directly switch the bed to a non-automatic adjustment use state.

Naturally, for some special users or crowds, some special information needs to be considered to be input as personal information in the data acquisition stage before the body model and the sleep pressure bearing model are established.

These particular information may include, among other things, the user's sleep preferences. In accordance with the present invention, there is provided,

these sleep preferences may include the following preference data that the user likes: for example, pillows prefer a height that can be classified, for example, as high (above 12cm), medium (8cm-12cm), and low (below 8 cm). The sleep preferences may also include: pillows prefer softness (soft, medium, hard), shoulders prefer softness (soft, medium, hard), waist prefer softness (soft, medium, hard), and buttocks prefer softness (soft, medium, hard), and so on.

Furthermore, these particular information, which are the basic information of the user, may also include the condition of the user. These conditions involving automatic adjustment of the bed may include, for example, conditions at various sites such as: neck, e.g., cervical spondylosis, etc.; shoulders such as scapulohumeral periarthritis (left scapulohumeral periarthritis, right scapulohumeral periarthritis) and the like; thoracic rib parts such as costalgia (left costalgia, right costalgia) and the like; lumbar, such as lumbar disc herniation and the like; buttocks, such as hip arthritis, sacral osteoarthritis, and the like; and general spine, such as ankylosing spondylitis, scoliosis, kyphosis, and the like. Since, in theory, the way the bed is adjusted will naturally be different for a user without the above-mentioned condition and for a user with one or more of the above-mentioned different conditions.

It is highly necessary that the bed will take this as a higher priority when the user has the relevant condition mentioned above, etc. present. For example, patients with cervical spondylosis sleep with physiological flexion of the neck and shoulder regions more important than other factors to be considered for adjustment. That is, when this need for adjustment conflicts with other needs for adjustment (e.g., maintaining reasonable pressure on the shoulders requires that the magnitude of adjustment for that position of the bed does not coincide with the magnitude of adjustment for that position required to maintain physiological flexion), the need for adjustment of the user for disease will be adjusted in preference to the other needs, such as when making adjustments.

According to this embodiment, the operation on the bed includes information input, the selection of the use mode is realized by means of a remote controller, and the adjustment program for realizing the above method is stored in a program memory and executed by means of calling. Alternatively, instead of the remote control, a small terminal such as a smart phone or a personal digital assistant may be used in combination with the App to operate the bed, including information input, usage mode selection, adjustment mode selection, and so on. Of course, other similar ways of performing the same function are also contemplated.

As can be seen from the above, according to the automatic adjustment method provided by the present invention, an intelligent control bed can be realized, which includes, as described above, an electric control part, a mechanical adjustment part, and a support part, wherein the electric control part is connected to the mechanical adjustment part, the mechanical adjustment part is slidably connected to the support part, the support part is divided into a predetermined number of regions, the regions respectively correspond to predetermined parts of a human body, and the electric control part may include: the device comprises a detection unit for detecting the pressure of the human body part transmitted by each partition of the supporting part, an adjusting unit for adjusting the mechanical adjusting part and a controller, wherein the controller can be realized in an electric control part or a remote controller, and other intelligent devices such as a smart phone can be considered in combination with an App. The automatic adjustment method according to the invention can be implemented when a program product stored in the memory means is executed on the controller. Accordingly, in one particular embodiment, such a smart control bed is presented. The intelligent control bed can have the following operation modes:

in the first mode: a fully automatic intelligent adjustment mode, which is the main operation mode of the intelligent control bed, in which the intelligent mattress is automatically identified and automatically adjusted by its sensing system and adjustment system, and thus in which it is mainly realized by means of the method proposed according to the invention.

In the second mode: a custom smart adjustment mode, which is based on and understood to be complementary to and fine-tuned to the first mode, in which case appropriate user self-initiative intervention is performed in situations where the user's subjective perception is not comfortable when automatic adjustment may occur. The mode mainly comprises the following steps:

the first step is as follows: and (3) recording the subjective comfortable state, wherein the user can autonomously set the subjective comfortable state in each sleeping posture in the step: this can be achieved, for example, by the user, in a sleeping position in which the user is relatively frequently lying down, lying on the left side, lying on the right side, or the like, manually adjusting the comfortable position or state of the head, neck, shoulder, back, waist, hip, leg, foot, or the like in this sleeping position while maintaining the sleeping position, and clicking the record and storing. The user can adjust to the most satisfied position or state of the user aiming at each sleeping posture, and clicks the record to store. Thus, the system can automatically record the sleeping posture characteristics and the corresponding comfortable position or state of the user at the moment.

The second step is that: the system automatically identifies and adjusts: after the sleeping postures and the adjusting positions or states are recorded by the system in the first step, the system automatically identifies the sleeping postures of the user in the sleeping process of the user, matches the sleeping posture characteristics set in the first step, can know that the user is in the lying posture, the left side lying posture, the right side lying posture or other set sleeping postures, and automatically adjusts the bed or the mattress to the originally set satisfactory positions or states. This may include, among other things: in the sleeping process of the user, whenever the user turns over or changes the sleeping posture, the system automatically updates and adjusts the sleeping posture so as to keep that each sleeping posture is adjusted to the satisfied position and state of the user in the whole sleeping process, and the most satisfied and comfortable sleeping experience is provided for the user.

In the third mode: the manual mode, if the user so wishes, can be through the mode of manual selection, for example through the remote controller or the App on the cell-phone, manually adjust the setting to intelligent mattress, different positions, for example head, neck, shoulder, back, waist, buttockss, leg, foot etc. position user can all set for oneself. Wherein the third mode differs from the second mode in that after the setting of the respective parts is completed in this mode, the bed or mattress does not undergo automatic adjustment changes, but remains in this state according to the setting manually by the user at that time.

A fourth mode: sleep partner adjustable mode, which essentially also belongs to one of the manual modes and as a special case of the manual mode, the mode aims to provide a bed position or state that allows one user to manually adjust the corresponding area of the sleep partner with him/her when sleeping in bed with two (e.g. couples) or three (e.g. couples plus children). For example, when the couple snores during sleeping, the bed positions or states of all the parts where the couple snores can be adjusted under the condition that the couple does not wake up the couple, so that the snore of the couple is weakened or eliminated.

A fifth mode: a flat bed mode in which the smart bed or mattress is returned to a normal flat bed for use. The realization method is that after the components of the intelligent bed are restored to the default positions, the automatic adjustment mode and the manual adjustment mode are closed or are in an inactive state.

A sixth mode: a massage mode in which the bed or mattress performs a wave massage or a vibration massage under the control of a fixed pattern of control signals, such as periodic or aperiodic.

Naturally, the six modes described above are only exemplary and should not be understood as limiting, and naturally further modes may be provided for user selection depending on the hardware and mechanical components of the bed or mattress.

In addition, for the intelligent bed, the user can select different modes through the remote controller or the mobile phone APP and other operation ends and switch at any time, and in addition, especially, the duration of each mode can be set, and the next mode can be automatically entered after the duration is over.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. It should be understood that the features disclosed in the above embodiments may be used alone or in combination, except where specifically noted. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Therefore, it is intended that the invention disclosed herein not be limited to the particular embodiments disclosed, but that it will include modifications within the spirit and scope of the present invention as defined by the appended claims.
