[0021] At present, when a smart bed (an intelligent electric bed) provides a function of adjusting the angle of the bed board, such as automatically lifting the back bed board (the bed board near the head of the bed) according to the user's sleeping state, as the lifting angle of the back bed board increases, the gap distance between the back bed board and the head of the bed will gradually increase. In response to this problem, an existing solution is: using time-sharing to lift the back bed board and adjust the bed frame, that is, the smart bed has the function of adjusting the bed frame in the horizontal direction. After the back bed board on the bed frame is lifted, the bed frame is adjusted in the horizontal direction, so that the bed frame gradually moves closer to the head of the bed until the gap distance between the back bed board and the head of the bed is the initial gap distance, and then stops moving, so as to achieve that the distance between the back bed board and the head of the bed after lifting remains unchanged compared to the gap distance between the back bed board and the head of the bed when not lifted. With the above existing solutions, it is impossible to achieve synchronous lifting of the back bed board and adjustment of the bed frame to achieve non-sensitive adjustment, and the user experience is relatively poor.

[0022] To this end, the present application provides a technical solution for synchronously adjusting the bed frame during the lifting movement of the back bed board, so that the gap distance between the back bed board and the head end of the bed remains unchanged in real time, thereby achieving a non-sensitive adjustment effect and providing users with a better smart bed experience.

[0025] Before introducing the method embodiment provided in the present application, for ease of understanding, a brief introduction and description of the smart bed provided in the present application is first given.

[0026] Figure 1a to Figure 1c The structure diagram of the smart bed provided by the embodiment of the present application is shown. Figure 1a to Figure 1c As shown, the smart bed A includes a bed body, on which a bed frame 5, a bed frame 51, etc. are arranged, wherein the bed frame 51 is arranged on the bed frame. The bed frame 51 includes a bed board (not shown in the figure). In specific implementation, the bed frame 51 can adopt but is not limited to a two-stage design, and correspondingly, the bed board can also adopt but is not limited to a two-stage design, and the bed board includes a back bed board near the head end of the smart bed and a foot bed board near the tail end of the smart bed, and the back bed board and the foot bed board can be connected by but is not limited to a hinged manner.

[0027] In addition, the smart bed A is also provided with a driving mechanism (not shown in the figure) for driving the back bed board to be lifted or lowered, and the driving mechanism may include but is not limited to a driver (such as a motor) and a rotating shaft. One end of the rotating shaft is connected to the output end of the driver, and the other end is rotatably connected to the side of the back bed board away from the head end; the driver drives the rotating shaft to rotate to drive the back bed board to be lifted or lowered.

[0028] Furthermore, the bed frame 51 is an electric bed frame, and the smart bed A is also provided with a driving mechanism for driving the bed frame 51 to move in the horizontal direction, and a slide rail component (not shown in the figure), etc. The bed frame 51 is set on the bed frame 4 through the slide rail.

[0029] In addition to the above, the smart bed A may also be provided with other components, such as a speaker 1, a projector 2, an electrical interface 3 (such as a USB interface), a fragrance outlet 4, an infrared sensor 6 (set at the bottom of the bed), a mattress 7, a control button 8, a screen assembly, a light strip 12, a control device 13 (or a control device), an air duct system 14, a spotlight 15, etc., which are not specifically limited here.

The control device 13 can be used to control all components on the smart bed, for example, to control the drive mechanism corresponding to the bed frame, the drive mechanism corresponding to the back bed board, etc.

[0030] For other components that the above-mentioned smart bed may include, please refer to the components that an existing smart bed may include, and no further details will be given here.

[0031] The method embodiments provided in this application are described in detail below.

[0032] Figure 2 The flowchart of the intelligent bed control method provided by an embodiment of the present application is shown. The execution subject of the method is an intelligent bed with a back bed board that can be raised on the bed frame, as described above. Figure 1a to Figure 1cIn the smart bed shown in FIG. 1 , the back bed board is close to the head end of the smart bed; more specifically, the execution subject may be a control device on the smart bed, such as Figure 1c The control device 13 shown in the figure is a device with data processing, computing and analysis capabilities, such as but not limited to MCU (Micro Control Unit). Figure 2 As shown, the intelligent bed control method provided in this embodiment includes the following steps:

[0033] 101. When a lifting start signal is detected, determining that the back bed board starts to lift;

[0034] 102. During the movement of the back bed board, control the first gap distance between the back bed board and the bed head end to remain unchanged;

[0035] The first gap distance refers to the gap distance between the back bed board and the head end when the back bed board is not raised.

[0036] In the above 101, the lifting start signal can be automatically triggered by the smart bed according to the data corresponding to the user. For example, during the user's sleep, when the user's snoring is detected, a lifting start signal will be triggered and sent to the drive mechanism corresponding to the back bed board. In response to the lifting start signal, the drive mechanism will start working to drive the back bed board to lift until it is lifted to a certain angle (such as 15°) to allow the user to breathe more smoothly, thereby achieving the effect of stopping snoring. After the snoring stops, a descending start signal can be automatically triggered and sent to the drive mechanism corresponding to the back bed board; in response to the descending drive signal, the drive mechanism will drive the back bed board to descend to restore it to its original position.

[0037] Alternatively, the lifting start signal can also be passively triggered according to the user's operation. For example, if the user wants to read a book before going to bed, the user can press the corresponding control button 8 on the smart bed or the application software of the smart bed installed on the terminal to trigger the lifting operation for the back bed board; the smart bed will generate a lifting start signal in response to the user's triggering of the lifting operation and send it to the driving mechanism corresponding to the back bed board; the driving mechanism responds to the lifting start signal and starts working to drive the back bed board to lift until it is lifted to a certain angle (such as 45°), so that the user can read books comfortably on the mattress. When the user wants to fall asleep, the corresponding control button 8 on the smart bed or the application software of the smart bed installed on the terminal can be used to trigger the lowering operation for the back bed board; the smart bed will generate a lowering start signal in response to the user's triggering of the lowering operation and send it to the driving mechanism corresponding to the back bed board; the driving mechanism responds to the lowering start signal and starts working to drive the back bed board to lower and return to its original position.

[0038] During the lifting movement of the back bed board, the corresponding translation speed can be determined in real time for the bed frame according to the lifting angle of the back bed board, so as to control the bed frame to move in the horizontal direction according to the determined translation speed in real time, so as to achieve the purpose of controlling the distance between the back bed board and the head end to remain unchanged. Based on this, in an achievable technical solution, the above 102 "controlling the first gap distance between the back bed board and the head end to remain unchanged" can specifically include:

[0039] 1021. Obtain the current lifting angle of the back bed board;

[0040] 1022. Determine the required translation speed of the bed frame at the current moment according to the lifting angle;

[0041] 1023. Drive the bed frame to translate toward the bed head end according to the translation speed, so that the first gap distance between the back bed board and the bed head end remains unchanged;

[0042] The first gap distance mentioned above refers to the gap distance (a fixed value, usually a relatively small value) between the back bed board and the head end of the bed before the back bed board is lifted (ie, the lifting angle is 0), such as 0, 1 cm, etc.

[0043] In the specific implementation, the movement of the back bed board (such as lifting movement and lowering movement) is driven by the corresponding driving mechanism on the smart bed. The driving mechanism may include a driver and a rotating shaft, etc. The driver drives the rotating shaft to rotate to drive the back bed board to lift or lower. Among them, each time the driving shaft rotates one circle, the lifting angle of the back bed board will increase or decrease by a certain angle accordingly. For example, the driver drives the rotating shaft to rotate inward for one circle, which can drive the lifting angle of the back bed board to increase by 0.5°, and the driving shaft rotates outward for one circle, which can drive the lifting angle of the back bed board to decrease by 0.5°. Therefore, the lifting angle of the back bed board at the current moment can be determined according to the initial lifting angle before the back bed board moves and the number of rotations of the driving mechanism corresponding to the back bed board from the start of the work to the current moment. Of course, other methods can also be used to determine it. For example, if an angle sensor for detecting the lifting angle of the back bed board is arranged on the smart bed, the lifting angle of the back bed board can also be determined by the angle sensor. This embodiment does not specifically limit the method for determining the lifting angle. Furthermore, according to the determined lifting angle, the translation speed of the bed frame at the current moment can be determined, so as to control the bed frame to translate in a corresponding direction, so that the first gap distance between the back bed board and the head of the bed remains unchanged.

[0044] For example, assuming that the back bed board is lifting, the lifting angle of the back bed board at the current moment is θ1, and according to the lifting angle θ1, the corresponding translation speed of the bed frame at the current moment is determined to be v1, then the bed frame will be driven by the driving mechanism corresponding to the bed frame to translate forward at the translation speed v1 (i.e., translate in the direction close to the bed head end), so that the distance between the back bed board and the bed head end is reduced to the first gap distance. Further, when the lifting angle of the back bed board increases from θ1 to θ2 at the next moment, the distance between the back bed board and the bed head end will increase again; according to the lifting angle θ2, after determining that the corresponding translation speed of the bed frame at the next moment is v2, the bed frame will be driven by the driving mechanism corresponding to the bed frame to translate forward at the translation speed v2 (i.e., translate in the direction close to the bed head end), so that the distance between the back bed board and the bed head end is reduced to the first gap distance. By analogy, the purpose of controlling the distance between the back bed board and the bed head end to remain unchanged in real time during the lifting movement of the back bed board is achieved.

[0045] In a specific implementation scheme, the above 1022 "determine the translation speed corresponding to the bed frame at the current moment according to the lifting angle" can be implemented by the following steps:

[0046] 10221. Obtain parameter information related to the bed frame;

[0047] 10222. Determine the translation speed according to the parameter information and the lifting angle.

[0048] In the above 10221, the parameter information may include the size of the back bed board (such as length, width), and the rotational angular velocity of the driving mechanism for driving the back bed board to lift. In addition, the parameter information may also include other parameters, such as the size of the bed frame (length, width). This embodiment does not limit the specific content that the parameter information may include.

[0049] The driving mechanism for driving the back bed board to lift is connected to the side of the back bed board away from the bed head end. According to the above parameter information, the distance from the side of the back bed board close to the bed head end to the driving mechanism can be determined first, so as to use this distance and the lifting angle to determine the translation speed. Based on this, an achievable method of the above 10222 "determining the translation speed according to the parameter information and the lifting angle" may include the following steps:

[0050] S11, determining the length from the side of the back bed board close to the bed head end to the driving mechanism according to the bed board size of the back bed board;

[0051] S12. Determine the translation speed according to the length, the rotation angle of the driving mechanism and the lifting angle.

[0052] In a specific implementation, the driving mechanism for driving the back bed board to lift is arranged on the bed frame, which may include a driver (such as a motor) and a rotating shaft, wherein one end of the rotating shaft is connected to the output end of the driver, and the other end is rotatably connected to the side of the back bed board away from the head end. Based on this, the length distance mentioned above may specifically refer to the distance from the side of the back bed board close to the head end to the rotating shaft in the driving mechanism, which may be determined according to the length of the back bed board. Since the bed board size of the back bed board is fixed, the length distance is also a fixed constant value set according to the length of the back bed board. For example, the length distance may be directly the length of the back bed board.

[0053] exist Figure 3 In the figure, the length distance L from the side of the back bed board close to the head end to the driving mechanism is specifically shown.

[0054] Further, after the length distance is determined, the translation speed can be calculated according to the length distance, the rotation angular velocity of the drive mechanism, the lifting angle, and the cosine value of the lifting angle. Specifically, an achievable solution of the above S12 "determining the translation speed according to the length distance, the rotation angle of the drive mechanism, and the lifting angle" can be implemented by the following specific steps:

[0055] S121, determining a numerical difference from the cosine value of the lifting angle;

[0056] S122. Multiply the length, the rotation angle, the data difference, and the inverse of the lifting angle to obtain the translation speed.

[0057] The translation speed described in the above steps 121 to 122 is determined, and the corresponding data expression is as follows:

[0058] V t =L*W*(1-cosθ t ) / θ t

[0059] Wherein, t represents the current moment; V represents the required translation speed of the bed frame at the current moment; L represents the length from the back bed board to the side close to the head end of the bed to the driving mechanism; W represents the rotational angular velocity of the back bed board driven by the driving mechanism; θ represents the lifting angle of the back bed board at the current moment.

[0060] In another specific implementation scheme, the above 1022 "determine the required translation speed of the bed frame at the current moment according to the lifting angle" can be implemented by the following steps:

[0061] 10221', obtaining a preset correspondence table; wherein the correspondence table contains correspondence information between a lifting angle and a translation speed;

[0062] 10222'. According to the correspondence table, determine the translation speed corresponding to the lifting angle as the translation speed required for the bed frame at the current moment.

[0063] In specific implementation, the above correspondence table is obtained by performing a large number of lifting tests on the back bed board, and then by statistically analyzing and calculating the gap distances between the back bed board and the head end of the bed at different lifting angles recorded during the test. Among them, the translation speed contained in the correspondence table is obtained by calculating the ratio of the gap distance increase value to the time increase value, that is, the mathematical expression of the translation speed contained in the correspondence table is as follows:

[0064]

[0065] in, Respectively represent the t recorded during the test i The gap between the back of the bed and the head of the bed, and t i-1 The gap distance from the back of the bed board to the head of the bed at that moment, V is the translation speed.

[0066] For example, referring to the statistical data information of the lifting test for the back bed board shown in Table 1, let t0 be the start time of the test. At this time t0, the lifting angle and gap distance of the back bed board are both 0. Afterwards, at time t1, the lifting angle increases from 0 to θ 11 , the gap distance increases from 0 to d 11 , then the translation speed corresponding to time t1 can be calculated as (d 11 -0) / (t1-0); and by analogy, a corresponding relationship table of "lifting angle <—> moment <—> gap distance <—> translation speed" can be formed in the end.

[0067] Table 1

[0068]

[0069]

[0070] It should be noted that during the lifting test of the back bed board, the bed frame is not driven to translate. Table 1 shows data information such as the lifting angle θ, time t, and gap distance d, which can be the corresponding mean values ​​obtained by statistically analyzing the data information recorded in multiple tests. When recording data, the recording interval time can be determined based on, but not limited to, the time taken by the drive mechanism corresponding to the back bed board to rotate a preset number of circles (such as 1 circle, 2 circles, etc.). When actually constructing the correspondence table, it is often required that the lifting angle gradient in the correspondence table is as small as possible, but due to the complexity of the actual test operation, the lifting angle gradient is usually 1°. Based on this requirement, if it is assumed that the driving mechanism corresponding to the back bed board rotates 2 circles, the lifting angle of the back bed board will increase by about 1°, and the time taken by the driving mechanism corresponding to the back bed board to rotate 2 circles is 3 seconds, then during the test, data can be recorded every 3 seconds.

[0071] The correspondence table formed above will be built into the control device set on the smart bed, so that the control device can be called when it detects that the back bed board is lifting and controls the first gap distance between the back bed board and the head end to remain unchanged.

[0072] For example, during the lifting movement of the back bed board, the translation speed corresponding to the current lifting angle of the back bed board at the current moment is found from the called correspondence table, and the translation speed required for the bed frame at the current moment is determined at this time; further, in order to improve the accuracy of control, the gap distance corresponding to the current lifting angle can also be found from the correspondence table (for the convenience of description, it is recorded as the second gap distance), so as to accurately control the horizontal movement of the bed frame according to the translation speed, the second gap distance, and the first gap distance to be controlled between the back bed board and the head end. For example, according to the translation speed found, the bed frame can be driven to move in the direction close to the head end by a distance equal to the difference between the second gap distance and the first gap distance, so that the first gap distance between the back bed board and the head end remains unchanged. In addition, in some cases, the distance mentioned above can be further determined in combination with the gap distance corresponding to the previous lifting angle on the back bed board at the previous moment obtained according to the correspondence table (for the convenience of description, it is recorded as the third gap distance).

[0073] To facilitate understanding, the contents of the above example are described in detail below with reference to a specific schematic diagram.

[0074] In the detailed description, it is still assumed that the driving mechanism corresponding to the back bed board will increase the lifting angle of the back bed board by about 1° for every 2 rotations, and that the driving mechanism corresponding to the back bed board takes 3 seconds to rotate 2 rotations. It is also assumed that the gap distance between the back bed board and the head end is 0 when the back bed board is not lifted (that is, the first gap distance is 0), and during the lifting process of the back bed board, the smart bed determines the lifting angle of the back bed board every 3 seconds. Then:

[0075] See also Figure 4 , after 3s (current time t=3s) since the back bed board starts to lift, it is determined that the lifting angle of the back bed board increases from 0 to θ1. After searching in the preset corresponding relationship table (such as referring to Table 1), it is determined that the difference between the current lifting θ1 of the back bed board and the lifting angle θ11 in the corresponding relationship table is the smallest and within the preset difference range, then the gap distance d11 and the translation speed V11 corresponding to the lifting angle θ11 in the corresponding relationship table are respectively determined as the second gap distance and the translation speed that have a corresponding relationship with the current lifting angle θ1 of the back bed board. In order to keep the gap distance between the back bed board and the head end of the bed still 0, from the current moment, while the back bed board is lifting, it will also drive (or push) the bed frame to translate forward (in the direction indicated by the arrow V, that is, toward the head end) at the translation speed V11, and the translation distance is d11-0, that is, the distance between the vertical line l0 and the vertical line l1. After translation, the position of the end of the back bed board away from the head end relative to the smart bed will change from position O to position O'.

[0076] Furthermore, after another 3s (i.e., the current moment is t=6s), it is determined that the lifting angle of the back bed board has increased from θ1 to θ2. After searching in the preset correspondence table, it is determined that the difference between the current lifting angle θ2 of the back bed board and the lifting angle θ12 in the correspondence table is the smallest and within the preset difference range. Then, the gap distance d12 and the translation speed V12 corresponding to the lifting angle θ12 in the correspondence table are respectively determined as the second gap distance and the translation speed that are corresponding to the current lifting angle θ2 of the back bed board. Since the above-mentioned gap distance d12 is obtained through testing, the gap distance d12 usually refers to the gap distance between the back bed board and the head end when the position of the end of the back bed board away from the head end relative to the smart bed is position O, and now after the bed frame is translated, the position of the end of the back bed board away from the head end relative to the smart bed is position O'. Therefore, in order to keep the gap distance between the back bed board and the head end still 0, the distance that the bed frame needs to be translated forward from the current moment should be: d12-the translation distance of the bed frame-0, wherein, as of the current moment (t=6s), the translation distance (total translation distance) of the bed frame is controlled to be d11-0; therefore, from the current moment (t=6s), while the back bed board is lifted, the bed frame will also be driven to translate forward at a translation speed V12, and the translation distance D is d12-the translation distance of the bed frame-0.

[0077] It should be noted that the bed frame driven in the context of this embodiment is realized by the driving mechanism corresponding to the bed frame. After determining the parameters such as the translation speed, a driving instruction can be generated according to the translation speed and sent to the driving mechanism corresponding to the bed frame; the driving mechanism corresponding to the bed frame responds to the driving instruction and executes the driving operation to drive the bed frame to translate according to the translation speed and other parameters contained in the driving instruction.

[0078] Based on the above content, the correspondence table also includes: correspondence information between the lifting angle and the gap distance; and, accordingly, in the above 1023, "according to the translation speed, driving the bed frame to translate in the direction close to the bed head end so that the first gap distance between the back bed board and the bed head end remains unchanged" can be implemented by the following steps:

[0079] According to the corresponding relationship information, a second gap distance corresponding to the lifting angle is acquired;

[0080] determining a translation distance that the bed frame has been translated;

[0081] Calculating a distance difference between the second gap distance, the translation distance, and the first gap distance;

[0082] According to the translation speed, the bed frame is driven to translate the distance difference in a direction close to the bed head end, so that the first gap distance between the back bed board and the bed head end remains unchanged.

[0083] In summary, the technical solution provided by this embodiment can simultaneously control the first gap distance between the back bed board and the head end to remain unchanged in real time during the lifting movement of the back bed board, wherein the first gap distance refers to the gap distance between the back bed board and the head end when the back bed board is not lifted, and the user can be unaware of it during the control process, which can bring users a better experience of using the smart bed. Specifically, during the lifting movement of the back bed board, when the first gap distance between the back bed board and the head end is controlled to remain unchanged, the corresponding required translation speed of the bed frame is determined in real time according to the lifting angle of the back bed board at different times, so that the bed frame is controlled to translate according to the determined translation speed while the back bed board is lifting, thereby achieving the effect of controlling the first gap distance between the back bed board and the head end to remain unchanged and making the user unaware of it during the control process.
