The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Example one

Referring to fig. 1-2, the present embodiment provides an intelligent bed screen without a driving mechanism, which comprises a bed screen main body 1, an adjustable supporting assembly, an inflation device, a deflation device and a control device 7. The adjustable supporting component comprises a supporting air bag 2 arranged on the bed screen main body 1 and a pressure sensor 8 used for sensing the air pressure in the supporting air bag 2. The inflator is used to deliver gas to the interior of the support airbag 2. The deflation means is used for releasing the gas inside the support airbag 2. The control device 7 is respectively electrically connected with the pressure sensor 8, the inflation device and the deflation device and is used for controlling the air pressure in the supporting air bag 2.

It should be understood that the problem that the user experience is poor due to the fact that the traditional bed screen cannot support and adjust according to the sitting posture of the user is solved, and two aspects of improvement are needed; secondly, when the sitting posture of the user changes, the supporting force required by the back of the user changes, the supporting force provided by the supporting structure for the user can be adjusted adaptively, for example, when the back of the user is nearly vertical, the supporting force can be small, but when the back of the user is nearly flat, the supporting force needs to be large, namely when the user changes from straight sitting to paralytic sitting, the supporting force needs to be increased, and when the user changes from paralytic sitting to straight sitting, the supporting force needs to be reduced.

According to the intelligent bed screen without the driving mechanism, on one hand, the supporting air bag 2 is used as a supporting structure contacted with the back of the user, the supporting air bag 2 can be kept attached to the back of the user at any time along with the change of the sitting posture of the user, so that the supporting is provided for the user, and the attaching degree of the supporting air bag to the back of the user is high; when a user leans against the supporting airbag 2, if the user feels that the supporting airbag 2 is too soft or the supporting force is insufficient, the pressure in the supporting airbag 2 is low, and the control device 7 can start the inflating device to deliver gas to the supporting airbag 2 to increase the pressure in the supporting airbag 2, so that the supporting force provided by the supporting airbag 2 to the user is improved; on the contrary, if the user feels that the supporting airbag 2 is too hard or the supporting force is too large, which indicates that the air pressure in the supporting airbag 2 is high, the control device 7 may activate the deflation device to release the air in the supporting airbag 2 to reduce the air pressure in the supporting airbag 2, thereby reducing the supporting force provided by the supporting airbag 2 to the user. The intelligent bed screen that does not take actuating mechanism that this embodiment provided, one need not to use actuating mechanism such as motor or cylinder and can keep hugging closely with user's back along with the change of user's position of sitting, two can carry out adaptability to the support strength according to user's needs and adjust, greatly improved user experience.

It should be noted that the pressure sensor 8 can sense the air pressure in the air bag supporting the air bag 2 to prevent over inflation or over deflation.

Further, the supporting airbags 2 of the adjustable supporting assemblies in the same supporting area are sequentially arranged from top to bottom.

For example, if the bed screen main body 1 is suitable for a single bed, a support area may be provided at the center of the bed screen main body 1; if the bed screen main body 1 is suitable for a twin bed, two support areas arranged in parallel left and right may be provided at the middle position of the bed screen main body 1. Of course, as the size of the bed screen body 1 increases, three, four or even more laterally aligned support areas may be provided. It will be appreciated that only one larger size support cell 2 may be used in the same support region to provide support for both the shoulder and lumbar regions; it is also possible to provide two smaller support cells 2, the upper support cell 2 providing support for the shoulders and the lower support cell 2 providing support for the waist. Of course, three, four or even more support cells 2 may be provided in order to facilitate fine control of the support force to which each position of the back is subjected.

Optionally, the inflation device includes an inflator 4 and a plurality of air intake valves 5, and the deflation device is a deflation valve 6. Specifically, each support airbag 2 is connected with an air inlet valve 5 and an air release valve 6, and all the air inlet valves 5 are communicated with the inflator 4. When a certain supporting air bag 2 needs to be inflated, the control device 7 starts the inflator 4 and opens the corresponding air inlet valve 5, and when a certain supporting air bag 2 needs to be deflated, the control device 7 opens the corresponding deflation valve 6. Alternatively, the control device 7, the inflator 4 and the like may be fixed to the side or edge of the bed screen main body 1.

In this embodiment, a support plate 3 is arranged between the support airbag 2 and the bed screen main body 1.

Optionally, the bed screen main body 1 is provided with a containing groove 101 capable of containing the support plate 3, a push-pull mechanism such as an air cylinder is arranged in the containing groove 101, when the support air bag 2 needs to be used, the push-pull mechanism pushes out the support plate 3, and when the support air bag 2 does not need to be used, the push-pull mechanism retracts the support plate 3 to be hidden in the containing groove 101.

Optionally, the supporting plate 3 is detachably connected with the bed screen main body 1. As an optional detachable connection mode, the support plate 3 is fixedly provided with a magnet, the bed screen main body 1 is fixedly provided with an iron block, and the support plate 3 is magnetically connected with the bed screen main body 1 through the magnet and the iron block; or the bed screen main body 1 is provided with a slot with an upward opening, the support plate 3 is provided with a 7-shaped insertion block extending downwards, and the 7-shaped insertion block can be inserted into the slot from top to bottom; or, a fixing nut is fixedly arranged on the bed screen main body 1, a bolt hole is formed in the supporting plate 3, and a fixing bolt penetrates through the bolt hole to be in threaded connection with the fixing nut; or the support plate 3 is buckled with the bed screen main body 1 through a hidden buckle; alternatively, the support plate 3 is bonded to the bed panel main body 1 by double-sided tape or the like.

Optionally, the control device 7 includes a timer, and the timer is electrically connected to the inflation device and the deflation device respectively, and is used for recording the inflation time of the inflation device and the deflation time of the deflation device.

In the present embodiment, the operation time is used as the stop condition of the inflator and the deflating device when the inflation or deflation is performed. That is, when it is necessary to change the air pressure in the cells supporting the air bag 2, the inflator inflates or deflates, and the inflator or deflate stops operating after 2s for a prescribed time (for example, 2 s).

In some other embodiments, the amount of pressure change sensed by the pressure sensor 8 can also be used as the stop condition for the inflation device and the deflation device. For example, if it is desired to change the in-cell air pressure of the support airbag 2, the inflator inflates or deflates until the amount of change in the in-cell air pressure of the support airbag 2 reaches a prescribed pressure value (e.g., 0.1Bar), the inflator or deflate stops operating.

The smart bed screen provided in this embodiment may control the inflation device and the deflation device by using a button on the control device 7 or using a mobile terminal such as a smart phone connected to the control device 7 in a wireless communication manner, or may control the inflation device and the deflation device by using the control method provided in the second embodiment.

The embodiment provides an intelligent bed screen without a driving mechanism, which is suitable for an application scene of supporting and adjusting a user, on one hand, the supporting airbag 2 is used as a supporting structure, and the intelligent bed screen can be kept to be attached to the back of the user along with the change of the sitting posture of the user without using a driving mechanism such as a motor or an air cylinder; on the other hand, setting up controlling means 7 and controlling aerating device and bleeder, can carrying out the adaptability to supporting strength and adjust according to user's needs to solve traditional bed screen and can't support according to user's position of sitting and adjust and lead to the relatively poor problem of user experience.

Example two

The embodiment provides a control method suitable for the intelligent bed screen, which has corresponding functions and corresponding beneficial effects.

Referring to fig. 3, the control method includes:

s10: the pressure sensor 8 detects the air pressure in the bag supporting the air bag 2 in real time.

S20: when the change value of the air pressure in the supporting air bag 2 reaches the entering condition, the control device 7 enters an adjustable mode.

It will be appreciated that initially, without the user leaning against the smart bed screen, the pressure within the support cells 2 should be maintained at a constant value, which may alternatively be a lower initial pressure. When the user leans against the smart bed screen, which corresponds to a sudden squeezing of the support airbag 2, the intra-bag air pressure of the support airbag 2 will increase suddenly in a short time, and corresponding to this user scenario, in this embodiment, when the intra-bag air pressure of the support airbag 2 increases by more than a first threshold value (e.g. 0.3Bar) in a first time (e.g. 1s), the control device 7 enters the adjustable mode.

Optionally, before entering the adjustable mode, the support plate 3 is located in the accommodating groove 101, and the intelligent bed screen is kept in a standby state, that is, the inflation device and the air supply device are both turned off to save power, and only the pressure sensor 8 works. After entering the adjustable mode, the push-pull mechanism pushes the support plate 3 out, and the inflation device and the air supply device are powered on for standby and ready for inflation or deflation operation at any time.

Further, the first time and the first threshold are adjustable, which is equivalent to that the sensitivity of entering the adjustable mode is adjustable, so that the probability of entering the adjustable mode by mistake can be effectively reduced. For example, if the tunable mode is disturbed by frequent and inadvertent light contact with the support airbag 2, the first time may be extended and the first threshold may be increased to decrease the sensitivity of entering the tunable mode. If it is inconvenient that the support airbag 2 is often required to be pressed with a large force to enter the adjustable mode, the first time may be reduced and the first threshold value may be reduced to improve the sensitivity of entering the adjustable mode.

Preferably, the first time and the first threshold value may be adjusted by the control means 7, or the first time and the first threshold value may be adjusted by a mobile terminal communicatively connected to the control means 7.

S30: the control device 7 adjusts the air pressure in the bag supporting the air bag 2 to a predetermined pressure value.

In order to avoid the reduction of the service life of the support air bag 2 caused by the long-time high pressure bearing, the initial pressure of the air pressure in the air bag is generally lower, and after the adjustable mode is entered, the air charging device is started to increase the air pressure in the air bag to a preset pressure value. Specifically, the predetermined pressure value may be regarded as a reference for subsequent adjustment, and may be set at the time of factory shipment, or may be set by a user, or the control device 7 may record pressure data commonly used by the user for a period of time, such as a week or a month, and use an average value thereof as the predetermined pressure value.

S401: when the change value of the air pressure in the supporting air bag 2 reaches the inflation condition, the control device 7 controls the inflation device to inflate the supporting air bag 2.

Preferably, the control device 7 controls the inflator to inflate the support airbag 2 when the amount of decrease in the in-bag air pressure of the support airbag 2 in the second time is larger than a second threshold value. The application scenario is as follows: the user leans forward and can carry out automatic inflation.

Specifically, after the air pressure in the air bag rises to a predetermined pressure value, the user feels that the supporting force is too small, the user leans forward, the back presses the supporting air bag 2 to be small, the pressure in the air bag suddenly drops, and when the pressure in the air bag drops by a certain value in a short time, the control device 7 can understand that the user has leaned forward, the supporting air bag 2 needs to be inflated, and therefore the inflation device is started to inflate. Therefore, it is only necessary for the user to tilt the body forward by a certain amount and keep the body for a certain time to allow the control device 7 to automatically inflate the support airbag 2.

It will be appreciated that the setting of the second time and the second threshold may determine the sensitivity of the auto-inflation. For example, if a slight rotation of the body during use of the support airbag 2 results in self-inflation, the second time may be extended and the second threshold increased to reduce the sensitivity of the self-inflation. If the body needs to be greatly tilted forward to be automatically inflated during the use of the support airbag 2, the second time and the second threshold value can be reduced to improve the sensitivity of the automatic inflation.

Alternatively, the inflator may be inflated once every time the value of the change in the in-bag air pressure of the support airbag 2 reaches the inflation condition. Specifically, the inflation once may be the duration of the inflation process for a specified time or until the increase in the air pressure in the bladder reaches a preset value. For example, every time the user leans forward, it is automatically inflated for 2s, or it is automatically inflated to a boost of 0.1Bar, etc. If the user feels insufficient, the user can lean forward again to perform the second inflation.

S402: when the value of the change in the in-bag air pressure of the support air bag 2 reaches the deflation condition, the control device 7 controls the deflation device to deflate the support air bag 2.

Preferably, the control device 7 controls the deflation device to deflate the support balloon 2 when the increase of the intra-balloon air pressure of the support balloon 2 in the third time period is larger than a third threshold value. The application scenario is as follows: the user can press the supporting air bag 2 backwards, and the automatic air release can be carried out.

Specifically, after the air pressure in the air bag rises to a predetermined pressure value, the user feels that the supporting force is too large, the user leans back forwards to extrude the supporting air bag 2, the extrusion force of the back to the supporting air bag 2 is increased, the pressure in the air bag rises suddenly, when the pressure in the air bag rises by a certain value in a short time, the control device 7 can understand that the user leans back backwards, the supporting air bag 2 needs to be deflated, and therefore the deflation device is started to deflate. Therefore, it is only necessary for the user to tilt the body backward by a certain amount and keep it for a certain time to make the control device 7 automatically deflate the support airbag 2.

It will be appreciated that the setting of the third time and the third threshold may determine the sensitivity of the automatic deflation. For example, if a slight rotation of the body during use of the support balloon 2 results in automatic deflation, the third time may be extended and the third threshold increased to decrease the sensitivity of automatic deflation. If the body needs to be greatly reclined to automatically deflate during use of the support balloon 2, the third time can be reduced and the third threshold can be reduced to improve the sensitivity of the automatic deflation.

Alternatively, the deflation means deflates once every time the value of the change in the air pressure within the support air bag 2 reaches the deflation condition. Specifically, the deflation once may be the deflation process for a specified time or the deflation until the decrement in the air pressure in the bladder reaches a preset value. For example, whenever the user reclines, deflate automatically for 2s, or deflate automatically to a reduced pressure of 0.1Bar, etc. If the user feels insufficient, the user can lean back again to perform the second deflation.

S50: when the change value of the air pressure in the supporting air bag 2 reaches the exit condition, the control device 7 exits the adjustable mode.

In the present embodiment, when the increase of the in-bag air pressure of the support air bag 2 in the fourth time is larger than the fourth threshold value; the control means 7 exit the adjustable mode. The application scenario is as follows: the user will be able to exit the adjustable mode automatically by squeezing the support airbag 2 for a long time.

To distinguish from S402, the third time is different from the fourth time, and/or a fourth threshold is different from the third threshold. Preferably, the third time and the fourth time may be the same, and the fourth threshold is greater than the third threshold, that is, when the supporting airbag 2 is lightly pressed, the supporting airbag 2 is deflated, and when the supporting airbag 2 is heavily pressed, the adjustable mode is exited; the fourth time may be greater than the third time, and the fourth threshold is equal to the third threshold, i.e. the support airbag 2 is deflated when being squeezed for a short time, and the adjustable mode is exited when the support airbag 2 is squeezed for a long time.

Optionally, after exiting from the adjustable mode, the intelligent bed screen returns to the standby state, the air pressure in the air bag returns to the initial pressure, and the push-pull mechanism retracts the support plate 3 into the accommodating groove 101.

The embodiment provides a control method suitable for intelligent bed screen, is applied to the application scene of supporting the regulation to the user, and the user only need lean forward or hypsokinesis with the health just can realize automatic inflation or gassing, and it is convenient to adjust, very big promotion user experience.
