Description
[0001] Embodiments of this application relate to the technical field of smart households, and in particular, to a smart anti-falling bed.
[0002] A conventional bed is mainly composed of a bed body and a headboard, without any protective measure around the bed body for preventing a person from falling during deep sleep.
As a result, cases in which a sleeper falls from the bed occur from time to time. Falling from the bed with a certain height may easily cause unignorable damages to bodies of particularly children or the elders.
[0003] To prevent the sleeper from falling, in recent years, some novel beds with anti-falling functions gradually occur in the market. For example, both sides of the bed board are changed as being removable, and a bed board with high outside and low inside is formed through rising of the two sides of bed board. In this way, the sleeper is enabled to move toward a center direction by using gravity components of the human body, thus avoiding the falling of the sleeper. There is another bed that is provided with guard bars at both sides of a bed body, and the guard bars block the sleeper to prevent the same from falling.
[0004] The current bed products with the anti-falling functions in the market have problems during use processes. First, the existing bed products cannot effectively satisfy various requirements of users. When the person merely hopes to sit on the bed or semi-lean against the headboard, enabling of the anti-falling device undoubtedly brings in troubles to the user to get on and off the bed. Second, during the use process of the bed, usually a quilt, a bed sheet, and the like having particular thicknesses and whose sizes are slightly greater than the bed board need to be laid on the bed board. Frequently changing the shape of the bed board easily causes the laid quilt and bed sheet to crease and have surfaces that are difficult to be smoothened.
However, for the bed provided with guard bars at both sides of the bed body, an edge of the bed sheet may be easily overturned or the guard bars are difficult to be raised.
l
[0005] This application provides a smart anti-falling bed, to resolve a problem that it is easy for a user to fall from a bed during sleep. Moreover, the smart anti-falling bed provided in this application has a simple structure, can autonomously determine whether the user on the bed is in a sleep state, and automatically switch to an anti-falling form according to a determining result, thus ensuring safety of the user.
[0006] This application provides a smart anti-falling bed, including a bed body and a headboard located at one side of the bed body, where the smart anti-falling bed further includes an anti-falling component that is disposed at a side surface of the bed body; a plurality of pressure sensors that are evenly arranged are disposed at an upper surface of the bed body; a controller is disposed within the headboard; the anti-falling component is connected to a lower end of the bed body, and includes a base, lifting devices, lifting bars, and a blocking bar, where one side of the base is connected to the lower end of the bed body; there are two lifting devices that are respectively located at two sides of an inner cavity of the base; an upper end of each lifting device is connected to a lower end of one of the lifting bars; and both ends of the blocking bar are respectively connected to an upper end of one of the lifting bars; and the lifting device and the pressure sensor are respectively electrically connected to the controller.
[0007] The smart anti-falling bed provided in this application detects a top of the bed body by using the pressure sensors that are evenly arranged at the surface of the bed body, and analyzes a detection result by using the disposed controller. If the detection result shows that pressure values of a plurality of points are relatively mean, and the pressure values of all points meet a determining condition, it is determined that a person on the bed is in a sleep state; and at the same time, a movable anti-falling device is controlled to be enabled and move to a designated position, to prevent a sleeper from falling from both sides of the bed body.

[0016] Refer to FIG. 1. FIG. 1 is a perspective view of a smart anti-falling bed according to this application.
[0017] It may be learned from FIG. 1 that this application provides a smart anti-falling bed, including a bed body 1 and a headboard 2 located at one side of the bed body 1. The smart anti-falling bed further includes an anti-falling component 3 that is disposed at a side surface of the bed body 1. In this embodiment, the disposed anti-falling component 3 can block a sleeper, to achieve an anti-falling objective. However, whether to dispose an anti-falling component 3 at each side of the bed body 1 needs to be determined by considering a position where the bed is placed in a room and user requirements. If one side of the bed leans against a wall or there is another rest, the anti-falling component 3 needs not to be disposed.
[0018] A plurality of pressure sensors 11 that are evenly arranged are disposed at an upper surface of the bed body 1. The pressure sensor 11 is configured to test pressure at an upper portion and collect pressure information, and feed back the pressure information to a controller. In this embodiment, a quantity and a compact degree of the pressure sensors 11 are not limited. 3
It may be determined that if the pressure sensors 11 have a larger quantity and are arranged more compact, analysis results of tests are more accurate; this facilitates effective determining of a sleep state of a person. However, disposing excessive pressure sensors 11 may increase the device costs and increase manufacturing difficulty. Therefore, the disposing of the pressure sensors 11 needs to satisfy requirements on comprehensive performances of economy and sensitivity.
[0019] A controller 21 is disposed within the headboard 2. The pressure sensor ll is electrically connected to the controller 21.
[0020] The controller 21 is configured to integrate and analyze to obtain an analysis result based on a detected pressure value signal; and determine whether the person on the bed is in a sleep state at this time, that is, whether an entire body lies flat on the bed. After it is determined that the person on the bed is in the sleep state, the controller 21 controls the anti-falling component 3 to be enabled, so that the bed has an anti-falling function. Similarly, when the person wakes up and needs to get off the bed, the controller 21 also immediately controls the anti-falling component 3 to be disabled based on changes of the pressure value signal, so that the bed restores to an original status.
[0021] Specifically, a process in this embodiment for the controller 21 to determine whether a person is in a sleep state is: when a person gets on the bed, all pressure sensors 11 at positions covered by the person respectively transfer detected pressure values to the controller 21. At this time, if the person enters the sleep state, that is, the person lies flat on the bed, a contact area between the person and a bed surface is the largest, a quantity of the pressure sensors 11 that detect the pressure values is also the greatest. Correspondingly, gravity of the person may also be borne in a relatively large contact surface, and a plurality of detected pressure values received by the controller 21 are relatively small. On the contrary, at this time, if the person is not in the sleep state but sits on the bed or semi-leans against the headboard, the contact area between the person and the bed surface may be significantly reduced, and the quantity of the pressure sensors 11 that detect the pressure values may also be significantly reduced. Correspondingly, when the gravity of the person does not change, certain detected pressure values received by the controller 21 are significantly increased as compared with those when the person lies flat. Therefore, a proportion of the pressure value detected by a certain pressure 4 sensor 11 to a sum of the pressure values detected by all the pressure sensors 11 may be set as a condition for determining whether the person lies flat. For example, assuming that 10 pressure sensors 11 are covered when an adult lies flat, the pressure value of all the sensors may be distributed in a range of 5-15% of the gravity of this person. However, when the person is on the bed in a sitting posture, a kneeling posture, or another posture, merely four to five pressure sensors 11 are covered thereby. Moreover, due to a change of the posture of the person, the pressure value or pressure values of one or two pressure sensors 11 may reach 40-50% or even higher of the gravity of this person. Under a premise of such assumption, if it is set in the controller 21 that when the pressure value detected by a certain sensor is greater than 25% of the gravity of the person, an anti-falling function is not enabled. On the contrary, when the pressure values detected by all the sensors are all smaller than 25% of the gravity of the person, it is determined that the person lies flat at this time, that is, the person is going to fall asleep or has fallen asleep; and meanwhile, the anti-falling function is enabled, to achieve automatic control.
[0022] Further, when waking up, the sleeper only needs to sit up on the bed. in this case, the controller 21 receives a pressure change fed back by the pressure sensor 11, and a determining result is obtained according to a set determining condition to control a device to disable the anti-falling function. The anti-falling component 3 can automatically restore to an initial status, without affecting the person who wakes up to get off the bed.
[0023] Refer to FIG. 2. FIG 2 is a partial structural schematic diagram of an anti-falling component in a smart anti-falling bed according to this application.
[0024] The anti-falling component 3 is connected to a lower end of the bed body 1, and includes a base 31, lifting devices 32, lifting bars 33, and a blocking bar 34. One side of the base 31 is connected to the lower end of the bed body 1. There are two lifting devices 32 that are respectively located at two sides of an inner cavity of the base 31. The two lifting devices 32 operate at the same time to ensure that the blocking bar 34 stably ascends or descends. An upper end of each lifting device 32 is connected to a lower end of one of the lifting bars 33. Both ends of the blocking bar 34 are respectively connected to an upper end of one of the lifting bars 33. It should be noted that when the anti-falling component 3 does not work, an upper edge of the blocking bar 34 is lower than an upper plane of the bed body 1.
[0025] The lifting device 32 is electrically connected to the controller 21. The lifting device in 5 this embodiment may be an air cylinder, a gear structure, or a lifting mechanism in another form; this is not limited herein.
[0026] In this embodiment, because the anti-falling component 3 is connected to the lower end of the bed body 1, and there is a gap between the anti-falling component 3 and an upper end ofthe bed body 1, a quilt, a bed sheet, and the like laid above the bed body 1 may be enabled to freely hang down in the gap. Moreover, the anti-falling component 3 is not in contact with the bed sheet during an ascending process or a descending process, avoiding pulling the bed sheet.
Herein, it should be noted that to possibly not affect people to get on or off the bed, the gap between the anti-falling component 3 and the bed body 1 needs not to be excessively large, provided that the bed sheet is not scratched during the ascending or descending process.
Moreover, all constituent parts of the anti-falling component 3 need to be designed to be in a flat form, thus occupying less transverse space as possible.
[0027] In addition, a structure form of the blocking bar 34 is not limited in this embodiment.
The blocking bar 34 may be connected by a plurality of tubes, or may be an integral thin plate, and may be designed to have a plurality of forms under a premise of ensuring certain structural strength.
[0028] It may be learned from the foregoing technical solutions that a working process of the smart anti-falling bed provided in this embodiment is described below.
[0029] First, when a person gets on the bed, the pressure sensor 11 on the bed body 1 detects the pressure information, and feeds back the pressure information to the controller 21.
[0030] Second, the controller 21 determines whether a sleep condition is met based on the pressure information, and sends a control instruction to the lifting device 32 if the sleep condition is met.
[0031] Third, the lifting device 32 is enabled to drive the blocking bar 34 to ascend to a designated position.
[0032] Four, when the sleeper wakes up and sits up on the bed, the controller 21 determines again whether the sleep condition is met based on the pressure information, and sends a control instruction to the lifting device 32 to control the anti-falling component 3 to be reset.
[0033] Refer to FIG. 3. FIG. 3 is an internal structural diagram of a bed body in a smart anti-falling bed according to this application.
6
[0034] Refer to FIG. 4. FIG. 4 is a partial structural diagram of a moving block in a smart anti-falling bed according to this application.
[0035] It may be learned from FIG. 3 and FIG. 4 that in a feasible embodiment, the anti-falling component 3 is slidably connected to the bed body 1; and a motor 12, a threaded rod 13, a bearing 14, and a horizontal slider 16 are disposed within the bed body 1.
[0036] The motor 12 is fixed at a bottom end of the bed body 1.
[0037] An outer ring of the bearing 14 is fixed at a side wall of the bed body 1.
[0038] One end of the threaded rod 13 is connected to the motor 12, and the other end of the threaded rod 13 is connected to an inner ring of the bearing 14; and the threaded rod 13 may be driven by the motor to rotate.
[0039] The horizontal slider 16 is directly below the threaded rod 13, one end of the horizontal slider 16 is fixed at the side wall of the bed body 1, and the horizontal slider 16 is disposed to be parallel to the threaded rod 13.
[0040] The threaded rod 13 and the horizontal slider 16 both pass through a moving block 15, one side of the moving block 15 is connected to one end of a connecting bar 17, and the other end of the connecting bar 17 passes through the bed body 1 to be connected to the anti-falling component 3.
[0041] Further, the moving block 15 is provided with a threaded hole 151 and a smooth hole
152. The smooth hole 152 is directly below the threaded hole 151. The threaded hole 151 fits with the threaded rod 13, and the smooth hole 152 fits with the horizontal slider 16. When the threaded rod 13 rotates, due to limitation of the horizontal slider 16 to the moving block 15, the moving block 15 is enabled to move along a direction of the horizontal slider16 under an action of a threaded connection, so as to drive the anti-falling component 3 to move in a horizontal direction through the movement of the moving block 15 in the horizontal direction. It should be noted that to ensure a stable movement of the anti-falling component 3, a plurality of connecting bars 17 may be provided to be respectively connected to the base 31, and the plurality of connecting bars 17 are connected to the moving block 15 at the same time.
[0042] The motor 12 is electrically connected to the controller 21.
[0043] In the foregoing embodiment, the anti-falling component 3 is changed from merely moving in a vertical direction to move in a horizontal-vertical direction. In one aspect, when the 7 anti-falling component 3 does not work, the blocking bar 34 is enabled to be close to the bed body 1 as possible by adjusting a position in the horizontal direction of the anti-falling component 3, thus reducing interference in getting on and off the bed, and further having a function of clamping the bed sheet and the quilt at both sides of the bed body 1, thereby preventing the bed sheet and the quilt from moving in a transverse direction and deviating from a center. Under such premise, a control process of the controller 21 for the anti-falling component 3 is shown in FIG. 7 and FIG. 8, and specifically is as follows.
[0044] First, when it is determined that the anti-falling component 3 needs to be enabled, the controller 21 first controls the motor 12 to drive the threaded rod 13 to rotate, and the moving block 15 drives the anti-falling component 3 to move to an outer side for a distance.
[0045] Second, after the blocking bar 34 is separated from the bed sheet and the quilt 100, the controller 21 controls the lifting device 32 to be enabled to drive the blocking bar 34 to ascend to a designated height.
[0046] Third, after the blocking bar 34 reaches the designated height, the controller 21 further controls the motor 12 to rotate in a reverse direction, to drive the moving block 15 to drive the anti-falling component 3 to move to an inner side, until the lifting bar 33 is tightly close to the bed sheet and the quilt 100.
[0047] Four, when the anti-falling component 3 needs to be disabled, the controller 21 controls a corresponding part to return along an original path, and the specific process is not described herein in detail.
[0048] Herein, it should be noted that a thread direction of the threaded rod 13 is not limited in this embodiment. A rotation direction of the motor 12 needs to be adjusted according to a direction of the threaded rod 13, provided that the moving block 15 can move in a preset direction.
[0049] Refer to FIG. 5. FIG. 5 is a structural diagram of a control panel in a smart anti-falling bed according to this application.
[0050] It may be learned from FIG. 1 and FIG 5 that in an embodiment, a control panel 22 is provided at an upper portion of the headboard 2; the control panel 22 includes a manual automatic adjustment switch 221, a manual enabling switch 222, a manual disabling switch 223, and a touch screen 224; and the control panel 22 is electrically connected to the controller 21. 8
The control panel 22 is mainly configured to adjust an automatic or a manual mode of the bed. When not being required to be automatically enabled, the bed may be adjusted into the manual mode to save electric energy. If the bed is in the manual mode, the enabling or disabling of the anti-falling component may be controlled by pressing the manual enabling switch 222 and the manual disabling switch 223. The determining condition may be set and modified at any time by providing the touch screen 224, so that accuracy for the bed to adjust to be suitable for people at different ages and with different weights is determined, thus reducing an error rate.
[0051] Further, setting the manual mode may also enable the smart anti-falling bed to be suitable for being used by multiple people. For example, when there is a person that has fallen into deep sleep, a second person can first switch the bed into the manual mode and temporarily disable the anti-falling component 3; and after getting on the bed, the second person switches the bed into the automatic mode again.
[0052] Refer to FIG. 6. FIG. 6 is a schematic diagram of a controller in a smart anti-falling bed according to this application.
[0053] It may be learned from FIG. 6 that the controller 21 includes a signal receiving module 211, an analyzing and processing module 212, and a control module 213.
[0054] The signal receiving module 211 is configured to receive a pressure signal detected by the pressure sensor 11 and transfer the pressure signal to the analyzing and processing module
212.
[0055] The analyzing and processing module 212 is configured to determine whether a person on the bed is in a sleep state according to the received pressure signal, and send a control instruction to the control module 213 if a determining result is that the person is in the sleep state.
[0056] The control module 213 is configured to control enabling or disabling of the anti-falling component 3 according to the control instruction.
[0057] Optionally, the controller 21 further includes a time control module 214; and the time control module 214 is configured to set time intervals for detecting pressure and performing control. Because the person on the bed may lie flat for a short time but does not fall asleep, immediately enabling the anti-falling component 3 when it is detected that a condition is met undoubtedly may increase an energy consumption if the person on the bed is not willing to fall 9 asleep. Therefore, by providing the time control module 214, a system may be set to enable the anti-falling component 3 after the condition is met for a period of time. For example, it is set that the person on the bed is assumed to have fallen asleep when the condition is met for 10 minutes, and subsequently enabling the device may reduce unnecessary operations of the device because the person lies down temporarily.
[0058] Optionally, an outer side of the anti-falling component 3 is provided with a fluffy sheath. In one aspect, providing the fluffy sheath can increase comfort when the person is in contact with the fluffy sheath; and in another aspect, can also prevent a steel tube, a tube, or another material that makes into the blocking bar 34 from being exposed, thereby improving the aesthetic.
[0059] Optionally, an infrared detector 23 is disposed at a side surface of the headboard 2; a detection direction of the infrared detector 23 is along a side edge direction of the bed body 1; and the infrared detector 23 is electrically connected to the controller 21. Assuming that there is a user sitting on the bed, where the user merely lies flat with the upper part of the body on the bed and places two feet on the floor, at this time, if the blocking bar 34 rises because the condition is met, inconvenience may be brought to the user. To avoid the foregoing situation, in a preferable embodiment, the infrared detector 23 along the side edge direction of the bed body 1 is provided to detect whether the foregoing phenomenon occurs in this direction. If it is detected that there is a person at an edge of the bed, the infrared detector 23 immediately feeds back a signal to the controller 21. Although a test result of the pressure sensor 11 at this time satisfies a determining condition, the controller 21 still does not enable the anti-falling component 3.
[0060] Optionally, the blocking bar 34 is close to a middle portion of the bed body 1, and a length of the blocking bar 34 is greater than or equal to half of a length of the bed body 1. The blocking bar 34 is close to a middle portion as possible; and this may increase an anti-falling success rate. Moreover, a longer length of the blocking bar 34 facilitates blocking. Considering a space occupation and anti-falling effects, the length of the blocking bar 34 may be set to be at least half of the length of the bed body 1.
[0061] The smart anti-falling bed provided in this application detects a top of the bed body by using the pressure sensors that are evenly arranged at the surface of the bed body, and analyzes 10 a detection result by using the disposed controller. If the detection result shows that pressure values of a plurality of points are relatively mean, and the pressure values of all points meet the determining condition, it is determined that the person on the bed is in the sleep state; and at the same time, the movable anti-falling device is controlled to be enabled and move to a designated position, to prevent the sleeper from falling from both sides of the bed body. In addition, the bed in this application can effectively keep the bed sheet and the quilt from being affected during an anti-falling process.
