Description

Technical Field

[0001] The present invention relates to the technical field of furniture, and in particular to an intelligent bed screen with a driving mechanism and a control method thereof. Background Art

[0002] Most beds are equipped with a bed screen at the head of the bed. In order to facilitate the user to lean against the bed screen when sitting on the bed, the bed screen is usually tilted. The current bed screen is only a tilted wooden board, which does not have the function of telescopic movement. Therefore, the support method cannot be adjusted as the user's sitting posture changes, which greatly reduces the user experience.

[0003] Therefore, it is necessary to improve the existing bed screen to solve the problem that it cannot be supported and adjusted according to the user's sitting posture. Summary of the invention

[0004] One object of the present invention is to provide a smart bed screen with a driving mechanism and a control method thereof, which can adjust the support according to the user's sitting posture, thereby improving the user's experience.

[0005] To achieve the above objectives, on the one hand, the present invention provides a smart bed screen with a driving mechanism, comprising:

[0006] Bed screen body;

[0007] An adjustable support assembly, the adjustable support assembly comprising a support plate, a driving mechanism for driving the support plate to move closer to or away from a human body relative to the bed screen body, a buffer airbag fixed to a side of the support plate close to the human body, and a pressure sensor for sensing the air pressure in the buffer airbag:

[0008] A control device, wherein the control device is electrically connected to the pressure sensor and the driving mechanism respectively, and is used to control the distance that the support plate extends outward relative to the bed screen body.

[0009] Preferably, at least one supporting area is provided on the side of the bed screen body close to the human body, and at least one adjustable supporting component is provided in the supporting area.

[0010] Preferably, the support plates of the adjustable support assemblies in the same support area are arranged sequentially from top to bottom.

[0011] Preferably, a receiving groove for accommodating the adjustable supporting assembly is provided on one side of the bed screen body close to the supporting plate.

[0012] Preferably, the control device comprises a calculation device, which is electrically connected to the driving mechanism and is used to calculate the displacement distance of the support plate.

[0013] On the other hand, the present invention provides a control method applicable to the above-mentioned smart bed screen with a driving mechanism, which comprises:

[0014] The pressure sensor detects the air pressure inside the cushion airbag in real time;

[0015] When the change value of the air pressure inside the cushion airbag reaches the entry condition, the control device enters the adjustable mode;

[0016] The control device controls the driving mechanism to adjust the distance between the support plate and the bed screen body so that the support plate reaches an initial position;

[0017] When the change value of the air pressure in the cushion airbag reaches the extension condition, the control device controls the driving mechanism to cause the support plate to move away from the bed screen body;

[0018] When the change value of the air pressure in the cushion airbag reaches the retraction condition, the control device controls the driving mechanism to cause the support plate to approach the bed screen body;

[0019] When the change value of the air pressure inside the cushion airbag reaches an exit condition, the control device exits the adjustable mode.

[0020] Preferably, the change value of the air pressure inside the cushion airbag reaches the entry condition specifically:

[0021] The air pressure inside the cushion airbag increases by more than a first threshold value within a first period of time.

[0025] The air pressure inside the cushion airbag increases within a third time period and is greater than a third threshold.

[0026] Preferably, the change value of the air pressure in the cushion airbag reaches the exit condition:

[0027] The air pressure inside the cushion airbag increases by more than a fourth threshold value within a fourth time; the third time is different from the fourth time, and / or the fourth threshold value is different from the third threshold value.

[0028] The beneficial effects of the present invention are: providing a smart bed screen with a driving mechanism and a control method thereof. When a human body leans on the smart bed screen, the control device can adjust the distance between the support plate and the user's back by controlling the driving mechanism, so that the user can still get effective support after changing the sitting posture, thereby solving the problem that traditional bed screens cannot adjust the support according to the user's sitting posture, resulting in poor user experience.

[0041] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0042] Embodiment 1

[0043] See also Figure 1-2 This embodiment provides a smart bed screen with a driving mechanism 302, including a bed screen body 1, an adjustable support assembly and a control device 2. The adjustable support assembly includes a support plate 301, a driving mechanism 302 for driving the support plate 301 to move closer to or away from a human body relative to the bed screen body 1, a cushioning airbag 303 fixed to the side of the support plate 301 close to the human body, and a pressure sensor 304 for sensing the air pressure in the cushioning airbag 303. The control device 2 is electrically connected to the pressure sensor 304 and the driving mechanism 302, respectively, and is used to control the distance that the support plate 301 extends outward relative to the bed screen body 1.

[0044] The smart bed screen with a driving mechanism 302 provided in this embodiment can adjust the distance between the support plate 301 and the user's back by controlling the driving mechanism 302 when the human body leans on the smart bed screen, so that the user can still get effective support after changing the sitting posture, thereby solving the problem that traditional bed screens cannot adjust the support according to the user's sitting posture, resulting in a poor user experience.

[0045] For example, if the user changes from an upright sitting posture to a slumped sitting posture, the angle between the human body and the horizontal plane decreases, and the distance between the waist and the bed screen body 1 increases. The control device 2 can control the support plate 301 to move away from the bed screen body 1 until the cushioning airbag 303 fits the user's waist; similarly, if the user changes from a slumped sitting posture to an upright sitting posture, the angle between the human body and the horizontal plane increases, and the distance between the waist and the bed screen body 1 decreases. The control device 2 can control the support plate 301 to move appropriately towards the bed screen body 1 to prevent the cushioning airbag 303 from protruding too much and pressing against the user's waist, causing the user to feel uncomfortable.

[0046] It should be noted that the cushioning airbag 303 can not only provide a pressure measurement environment for the pressure sensor 304, but also prevent the support plate 301 from directly contacting the user, and provide a good fit with the user's back. It is understandable that the support plate 301 has good rigidity and is difficult to be highly fitted with the user's back. The cushioning airbag 303 is the opposite. When the user leans on the cushioning airbag 303, the cushioning airbag 303 can be adaptively deformed with the user's back to ensure a good fit with the user's back, thereby providing a better support experience for the user's back.

[0047] It should be noted that the pressure sensor 304 can sense the air pressure inside the cushion airbag 303 , and the sensing result can be used as a basis for the control device 2 to control the start and stop of the driving mechanism 302 .

[0048] Optionally, at least one support area is provided on the side of the bed screen body 1 close to the human body, and at least one adjustable support assembly is provided in the support area. Further, the support plates 301 of the adjustable support assemblies in the same support area are arranged in sequence from top to bottom.

[0049] For example, if the bed screen body 1 is suitable for a single bed, a support area can be set in the central position of the bed screen body 1; if the bed screen body 1 is suitable for a double bed, two support areas arranged side by side on the left and right can be set in the middle position of the bed screen body 1. Of course, as the size of the bed screen body 1 increases, three, four or even more laterally arranged support areas can be set. It can be understood that only one larger adjustable support assembly can be used in the same support area to provide support for the head, shoulders and waist at the same time; three smaller adjustable support assemblies can also be set separately, and the buffer airbag 303 of the upper adjustable support assembly provides support for the head, the buffer airbag 303 of the middle adjustable support assembly provides support for the shoulders, and the buffer airbag 303 of the lower adjustable support assembly provides support for the waist. Of course, in order to facilitate the detailed control of the support force received at each position of the back, three, four or even more buffer airbags 303 can also be set.

[0050] Optionally, a receiving groove 101 for accommodating the adjustable supporting assembly is provided on one side of the bed screen body 1 close to the supporting plate 301. When the buffer airbag 303 is needed, the driving mechanism 302 pushes the supporting plate 301 out. When the buffer airbag 303 is not needed, the driving mechanism 302 retracts the supporting plate 301 and hides it in the receiving groove 101.

[0051] Optionally, the control device 2 can be fixed to the side or edge of the bed screen body 1 , and the driving mechanism 302 can be fixed to the back of the bed screen body 1 or to the bottom of the accommodating groove 101 .

[0052] In this embodiment, the driving mechanism 302 can be a cylinder. The shell of the cylinder is fixed in the receiving groove 101 of the bed screen body 1, and the telescopic end is fixed on the support plate 301. The extension stroke of the telescopic end can control the distance between the support plate 301 and the bed screen body 1. Alternatively, the driving mechanism 302 includes a motor fixed to the back of the bed screen body 1, a turbine driven by the motor, and a worm gear with one end connected to the turbine gear, and the other end of the worm gear passes through the bed screen body 1 and is rotatably connected to the support plate 301 through a bearing or a ball head structure, so that the rotational motion of the motor can be converted into the linear motion of the support plate 301. Alternatively, the driving mechanism 302 includes a motor fixed in the receiving groove 101, a gear driven by the motor, and a rack gear meshed with the gear gear at one end, and the other end of the rack gear is fixed to the support plate 301, so that the rotational motion of the motor can also be converted into the linear motion of the support plate 301. As long as the driving mechanism 302 can realize the forward and backward motion of the support plate 301, its specific structure is not limited in this embodiment.

[0053] Optionally, the control device 2 includes a calculation device, which is electrically connected to the driving mechanism 302 and is used to calculate the displacement distance of the support plate 301 .

[0054] In this embodiment, when the position of the support plate 301 is adjusted, the displacement distance of the support plate 301 is used as the stop condition of the drive mechanism 302. That is, when the support plate 301 needs to be extended or retracted, the control device 2 controls the displacement distance of the support plate 301 to be a fixed value (for example, 2 cm) each time. When the displacement distance of the support plate 301 reaches 2 cm, the drive mechanism 302 stops working until the next adjustment instruction is received, and the control device 2 controls the support plate 301 to move 2 cm again. Specifically, if the drive mechanism 302 uses a cylinder, the calculation device can obtain the travel of the telescopic end to know the displacement distance of the support plate 301; if the drive mechanism 302 uses a motor, the calculation device can calculate the displacement distance of the support plate 301 by obtaining the number of rotations of the motor and the parameters such as the pitch of the turbine or gear.

[0055] In some other embodiments, the pressure value sensed by the pressure sensor 304 may be used as the stop condition of the driving mechanism 302. For example, the target value of the air pressure in the bag may be set to 3 Bar, and the driving mechanism 302 adjusts the position of the support plate 301 until the air pressure in the bag reaches the target value.

[0056] The smart bed provided in this embodiment can use the buttons on the control device 2 or use a mobile terminal such as a smart phone wirelessly connected to the control device 2 to start and stop the drive mechanism 302, or use the control method provided in Example 2 to start and stop the drive mechanism 302.

[0057] This embodiment provides an intelligent bed screen with a driving mechanism 302, which is suitable for application scenarios in which support and adjustment are required for users. On the one hand, a cushioning airbag 303 is used as a supporting structure, which is conducive to a good fit with the user's back; on the other hand, a control device 2 is provided to control the driving mechanism 302, and the position of the support plate 301 can be adjusted according to user needs, thereby adjusting the supporting force, ultimately solving the problem that traditional bed screens cannot be supported and adjusted according to the user's sitting posture, resulting in a poor user experience.

[0058] Embodiment 2

[0059] This embodiment provides a control method for the smart bed screen described in Embodiment 1, which has corresponding functions and corresponding beneficial effects.

[0060] See also Figure 3 , the control method comprises:

[0061] S10: The pressure sensor 304 detects the air pressure inside the cushion airbag 303 in real time.

[0062] S20: When the change value of the air pressure inside the cushion airbag 303 reaches the entry condition, the control device 2 enters the adjustable mode.

[0063] It is understandable that at the beginning, the user does not lean on the smart bed screen, and the pressure in the cushioning airbag 303 should maintain a constant value. Optionally, the constant value can be a lower initial pressure. When the user leans on the smart bed screen, it is equivalent to suddenly squeezing the cushioning airbag 303, so the air pressure in the cushioning airbag 303 will increase sharply in a short time. Corresponding to this user scenario, in this embodiment, when the air pressure in the cushioning airbag 303 increases by more than a first threshold value (e.g., 0.3 Bar) within a first time (e.g., 1s), the control device 2 enters the adjustable mode.

[0064] Optionally, before entering the adjustable mode, the support plate 301 is stored in the receiving slot 101, and the smart bed screen remains in a standby state, that is, the drive mechanism 302 is turned off to save power, and only the pressure sensor 304 is working. After entering the adjustable mode, the drive mechanism 302 is turned on to push the support plate 301 out.

[0065] Furthermore, the first time and the first threshold are adjustable, which is equivalent to the adjustable sensitivity of entering the adjustable mode, which can effectively reduce the probability of entering the adjustable mode by mistake. For example, if the adjustable mode is often entered due to accidentally touching the cushioning airbag 303, the first time can be extended and the first threshold can be increased to reduce the sensitivity of entering the adjustable mode. If the cushioning airbag 303 is often squeezed hard to enter the adjustable mode, the first time can be reduced and the first threshold can be reduced to increase the sensitivity of entering the adjustable mode.

[0066] Preferably, the first time and the first threshold value can be adjusted by the control device 2 , or by a mobile terminal that is communicatively connected to the control device 2 .

[0067] S30: The control device 2 controls the driving mechanism 302 to adjust the distance between the support plate 301 and the bed screen body 1 so that the support plate 301 reaches the initial position.

[0068] For convenience, before entering the adjustable mode, the support plate 301 is generally stored in the receiving slot 101. After entering the adjustable mode, the driving mechanism 302 first extends the support plate 301 forward to provide the user with appropriate support force. Of course, the initial forward distance after entering the adjustable mode can be specified for the support plate 301. For example, after entering the adjustable mode, the support plate 301 can be specified to extend forward by 20 cm, etc. The position of the support plate 301 after moving forward the initial forward distance is its initial position.

[0069] It is understandable that the initial position of the support plate 301 can also be determined by the air pressure in the bag. For example, when the support plate 301 extends forward, the air pressure in the cushioning airbag 303 will also increase accordingly. When the air pressure in the bag reaches a predetermined pressure value, it means that the support plate 301 has reached the initial position.

[0070] Specifically, the initial position can be regarded as a reference for subsequent position adjustment of the support plate 301. By adjusting the initial forward distance or the predetermined pressure value, the support force obtained by the user at the beginning after entering the adjustable mode can be adjusted. The initial forward distance or the predetermined pressure value can be set at the factory or by the user.

[0071] S401: When the change value of the air pressure inside the cushion airbag 303 reaches the extension condition, the control device 2 controls the driving mechanism 302 to force the support plate 301 to move away from the bed screen body 1.

[0072] Preferably, when the air pressure in the cushion airbag 303 decreases by more than a second threshold value within the second time, the control device 2 controls the drive mechanism 302 to cause the support plate 301 to move away from the bed screen body 1. This application scenario is: when the user leans forward, the drive mechanism 302 automatically pushes the support plate 301 forward a little.

[0073] Specifically, when the support plate 301 reaches the initial position, if the user feels that the support force is too small, the user can lean forward, at which time the pressure of the back on the cushioning airbag 303 becomes smaller, and the pressure in the airbag drops suddenly (when the pressure in the airbag drops by a certain value in a short time, the control device 2 can understand that the user has leaned forward), and the control device 2 controls the driving mechanism 302 to push the support plate 301 forward so that the support plate 301 provides support for the user. Therefore, for the user, only need to lean forward a certain amount and keep it for a certain time to make the control device 2 automatically push the support plate 301 out.

[0074] It is understandable that the second time and the second threshold setting may determine the sensitivity of automatically pushing out the support plate 301. For example, if a slight rotation of the body during the use of the cushioning airbag 303 will cause the support plate 301 to be automatically pushed out, the second time may be extended and the second threshold may be increased to reduce the sensitivity of automatically pushing out the support plate 301. If the body needs to lean forward significantly during the use of the cushioning airbag 303 to automatically push out the support plate 301, the second time may be reduced and the second threshold may be reduced to increase the sensitivity of automatically pushing out the support plate 301.

[0075] Optionally, each time the change in the air pressure in the cushion airbag 303 reaches the extension condition, the support plate 301 moves outward once. Specifically, the support plate 301 moves outward once may be the support plate 301 moves outward a specified distance or the support plate 301 moves outward until the air pressure increment in the bag reaches a preset value. For example, each time the user leans forward, the support plate 301 is automatically pushed out 2 cm, or the support plate 301 is automatically pushed out until the air pressure in the bag increases by 0.1 Bar, etc. If the user feels that it is not enough, he or she may lean forward again to move the support plate 301 outward for the second time.

[0076] S402 : When the change value of the air pressure inside the cushion airbag 303 reaches the retraction condition, the control device 2 controls the driving mechanism 302 to force the support plate 301 to move closer to the bed screen body 1 .

[0077] Preferably, when the air pressure in the cushion airbag 303 increases by more than a third threshold value within a third time, the control device 2 controls the driving mechanism 302 to cause the support plate 301 to move closer to the bed screen body 1. This application scenario is: when the user presses the cushion airbag 303 backward, the driving mechanism 302 automatically retracts the support plate 301 a little.

[0078] Specifically, if the user feels that the support force is too small, the user can lean back, at which time the pressure of the back on the cushioning airbag 303 increases, and the pressure in the airbag increases suddenly (when the pressure in the airbag increases to a certain value in a short time, the control device 2 can understand that the user has leaned back), and the control device 2 controls the driving mechanism 302 to retract the support plate 301 so that the support plate 301 provides the user with the space required to adjust the sitting posture. Therefore, for the user, only need to lean back a certain amount and keep it for a certain time to make the control device 2 automatically retract the support plate 301.

[0079] It is understandable that the settings of the third time and the third threshold value can determine the sensitivity of automatically retracting the support plate 301. For example, if a slight rotation of the body during the use of the cushioning airbag 303 will cause the support plate 301 to be automatically retracted, the third time can be extended and the third threshold value can be increased to reduce the sensitivity of automatically retracting the support plate 301. If the body needs to lean back significantly during the use of the cushioning airbag 303 to automatically retract the support plate 301, the third time can be reduced and the third threshold value can be reduced to increase the sensitivity of automatically retracting the support plate 301.

[0080] Optionally, each time the change in the air pressure in the cushion airbag 303 reaches the retraction condition, the support plate 301 moves inward once. Specifically, the support plate 301 moves inward once may be the support plate 301 moves inward a specified distance or the support plate 301 moves inward until the air pressure in the bag decreases to a preset value. For example, each time the user leans forward, the support plate 301 is automatically retracted by 2 cm, or the support plate 301 is automatically retracted until the air pressure in the bag is reduced by 0.1 Bar, etc. If the user feels that it is not enough, the user can lean back again to perform a second retraction adjustment of the support plate 301.

[0081] S50: When the change value of the air pressure inside the cushion airbag 303 reaches the exit condition, the control device 2 exits the adjustable mode.

[0082] In this embodiment, when the air pressure in the cushion airbag 303 increases by more than a fourth threshold value within a fourth time, the control device 2 exits the adjustable mode. This application scenario is: when the user pushes the cushion airbag 303 back with great force for a long time, the adjustable mode will be automatically exited.

[0083] In order to distinguish from S402, the third time is different from the fourth time, and / or the fourth threshold is different from the third threshold. Preferably, the third time can be the same as the fourth time, and the fourth threshold is greater than the third threshold, that is, lightly pressing the cushioning airbag 303 makes the support plate 301 retract a little, and heavily pressing the cushioning airbag 303 exits the adjustable mode; the fourth time can also be greater than the third time, and the fourth threshold is equal to the third threshold, that is, squeezing the cushioning airbag 303 for a short time makes the support plate 301 retract a little, and squeezing the cushioning airbag 303 for a long time exits the adjustable mode.

[0084] Optionally, after exiting the adjustable mode, the driving mechanism 302 retracts the support plate 301 into the accommodating groove 101, and the smart bed screen returns to the standby state.

[0085] It should be noted that if a plurality of adjustable support components are provided in the same support area, each adjustable support component can independently perform S10 to S50 provided in this embodiment. For example, if an upper adjustable support component 401 for supporting the head, a middle adjustable support component 402 for supporting the shoulders, and a lower adjustable support component 403 for supporting the waist are provided in the same support area. When the user leans on the support area, if the degree of compression of the upper adjustable support component 401 by the shoulders reaches the entry condition of the upper adjustable support component 401, the upper adjustable support component 401 enters the adjustable mode and independently performs S20 to S50. At this time, if the user's waist does not squeeze the cushioning airbag on the lower adjustable support component 403, the lower adjustable support component 403 will not extend.

[0086] Alternatively, if multiple adjustable support components are provided in the same support area, the adjustable support components can be synchronously linked to enter the adjustable mode, and then independently perform steps S30 to S50 after entering the adjustable mode. For example, if an upper adjustable support component 401 for supporting the head, a middle adjustable support component 402 for supporting the shoulders, and a lower adjustable support component 403 for supporting the waist are provided in the same support area. When the user leans on the support area, if the degree of pressure of the shoulder on the upper adjustable support component 401 reaches the entry condition of the upper adjustable support component 401, the upper adjustable support component 401, the middle adjustable support component 402 and the lower adjustable support component 403 enter the adjustable mode at the same time, and each pushes the corresponding support plate forward to its respective initial position (generally, users are accustomed to leaning on the bed screen body 1 in a backward-leaning posture, so the shoulders are closer to the bed screen body 1 and the waist is farther from the bed screen body 1. Therefore, the initial position of the upper adjustable support component 401 can be relatively close to the bed screen body 1, the initial position of the lower adjustable support component 403 can be relatively far away from the bed screen body 1, and the initial position of the middle adjustable support component 402 is centered), and then each adjustable support component independently executes S401 to S50.

[0087] Similarly, in this embodiment, if a plurality of adjustable support components are provided in the same support area, the adjustable support components can exit their respective adjustable modes independently of each other, or can exit the adjustable modes synchronously and in linkage.

[0088] This embodiment provides a control method suitable for a smart bed screen, which is used in application scenarios for adjusting support for users. The user only needs to lean forward or backward to automatically push out the support plate 301 or automatically retract the support plate 301. The adjustment is convenient and the user experience is greatly improved.

[0089] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
