Description

Technical Field

[0001] This invention relates to the field of folding smart bed technology, and more specifically, to a multifunctional folding smart bed. Background Technology

[0002] A folding bed is a type of bed that can be folded up for storage. It typically consists of a bed frame, bed boards, and other components. The bed boards can be reshaped to create smaller or larger sizes. With the continuous improvement of living standards, traditional folding beds are becoming more intelligent by incorporating electric devices, sensors, controllers, and other technologies. By sensing the status of the bed and the user's needs, more precise control can be achieved, which can improve sleep quality, reduce physical stress, and prevent spinal diseases.

[0003] However, existing multi-functional folding beds still have certain problems. To change the firmness of existing multi-functional folding beds, users need to manually add or remove the amount of expanding padding, making the firmness adjustment process complex and limiting comfort. Furthermore, it is difficult to automatically adjust the bed according to user needs. Additionally, in both winter and summer, adjusting the temperature requires manually placing electric heating blankets or cooling mats, limiting the temperature control options available for different seasons. Therefore, a multi-functional intelligent folding bed is proposed. Summary of the Invention

[0004] The technical objective of this invention is to address the above-mentioned shortcomings by providing a multifunctional folding smart bed. By adjusting the expansion degree of the air bladders, the comfort of the bed can be improved. The air bladders can provide heating while inflating, enhancing the comfort of the bed, especially in winter. In addition, when the user's body is in contact with the leather layer, the air bladders can draw away the heat from the area in contact with the body, providing ventilation and heat dissipation, thus improving the comfort of the bed in hot summer weather and solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional folding smart bed, comprising an outer frame of the bed, a first storage slot on one side of the outer frame of the bed, a second storage slot on the top of the outer frame of the bed, and a first bed board, a second bed board and a third bed board arranged sequentially on the top of the outer frame of the bed;

Several inflatable bladders are installed at equal intervals on the top of the first, second, and third bed boards. A second groove is provided on the bottom inner wall of each inflatable bladder. Gas channels are provided inside the first, second, and third bed boards. The air outlet of the air pump is connected to a first pipe. A solenoid valve assembly is installed inside the gas channel. The air outlet of the solenoid valve assembly is connected to several second pipes. Each second pipe passes through the gas channel and is connected to the second groove of each inflatable bladder.

[0007] An air intake box is installed at the bottom of the second bed board. An electric heating grid is installed inside the air intake box. A primary filter is embedded on one side of the air intake box. The air inlet of the air pump is connected to an air intake pipe. The end of the air intake pipe away from the air pump is connected to the inside of the air intake box. A temperature sensor is installed on the inner wall of the air intake box.

[0008] Preferably, the top of the inflatable bladder is fitted with a leather layer, on which several ventilation holes are distributed. A shell is embedded in the inner wall of the top of the inflatable bladder. Two sealing plates are symmetrically hinged to the inner wall of the shell. Two torsion springs are symmetrically fixed to the inner wall of the shell. One end of each torsion spring is fixedly connected to the bottom of the sealing plate. A through hole is provided at the bottom of the shell. A first magnetic plate is fixedly connected to the inner wall of the second groove. A second magnetic plate is fixedly connected to the outer wall of the shell. The width and length of the shell are both smaller than the width and length of the second groove. A pressure sensor is installed on the bottom inner wall of the second groove.

[0009] Preferably, a microcontroller is installed on the inner wall of the first groove. The control output terminal of the microcontroller is connected to the electrical control terminals of the motor, the telescopic cylinder, the air pump, and the solenoid valve group via wires. The signal output terminals of the pressure sensor and the temperature sensor are both connected to the signal input terminal of the microcontroller.

[0010] Preferably, two blocks are symmetrically installed on the inner walls of both sides of the housing. The blocks are located on top of the sealing plates, and a baffle is installed on the top of the housing. When the two sealing plates rotate upward, they abut against the bottom of the baffle.

[0011] Preferably, a movable plate is installed at the bottom of the support platform, and a slide rail is installed on the bottom inner wall of the first storage slot. The support platform is slidably installed on the slide rail via the movable plate.

[0012] Preferably, two high-efficiency filters are symmetrically installed inside the air intake box.

[0013] Preferably, the bottom of the second bed board is hinged with a telescopic rod, one end of which is hinged to the bottom inner wall of the second storage slot.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0018] I. This invention can switch between the state of a bed and a sofa by changing the shape of the first bed board and the second bed board, thereby improving the use value of the bed and the efficiency of space utilization.

[0019] Second, this invention installs several equidistantly arranged airbags on the top of the first, second, and third bed boards to form an airbag array. The firmness of the bed can be changed by adjusting the expansion degree of the airbags, thereby improving the comfort of the bed. At the same time, by activating the electric heating grid to heat the air inside the air intake box, the airbags can have a heating effect while inflating, further enhancing the comfort of the bed, especially when used in winter.

[0020] Third, this invention uses the second magnetic plate and the first magnetic plate to adsorb the shell of the air bladder into the second groove. When the air pump draws air, external gas can enter the air bladder through the vents on the leather layer, thereby drawing away the hot airflow from the part of the body that is in contact with the leather layer, which plays a role in ventilation and heat dissipation, and improves the comfort of the bed in hot summer weather.

[0021] Fourth, this invention can intelligently sense the location of the human body and control the expansion of the air bladder and ventilation and heat dissipation, thus improving the intelligence level of the bed. Attached Figure Description

[0033] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1-3 As shown, a multifunctional folding smart bed according to an embodiment of the present invention includes an outer frame 1, a first bed board 6, a second bed board 9, a third bed board 11, and an airbag 8.

[0036] Among them, such as Figures 1-6 As shown, a first storage slot 2 is provided on one side of the outer frame 1 of the bed, and a second storage slot 10 is provided on the top of the outer frame 1 of the bed. A first bed board 6, a second bed board 9, and a third bed board 11 are provided sequentially on the top of the outer frame 1 of the bed. The adjacent sides of the first bed board 6, the second bed board 9, and the third bed board 11 are hinged to each other. A telescopic cylinder 14 is installed inside the second storage slot 10. The piston rod of the telescopic cylinder 14 is hinged to the bottom of the second bed board 9. A support platform 3 is slidably installed inside the first storage slot 2. A rack 17 is fixedly connected to one side of the support platform 3. A first groove 25 is provided on the inner wall of one side of the first storage slot 2. An air pump 24 and a motor 26 are installed inside the first groove 25. A gear 27 is fixedly connected to the rotating shaft of the motor 26. The gear 27 meshes with the rack 17.

[0037] In this embodiment, the starting motor 26 drives the gear 27 to mesh with the rack 17 on one side of the support platform 3, enabling the support platform 3 to move out of and into the first storage slot 2. When the support platform 3 moves out, the first bed board 6 can be raised to the top of the platform, allowing the user's limbs to rest on the first bed board 6. When the support platform 3 moves in, the first bed board 6 can be rotated downwards to the side of the bed frame 1 of the support platform 3, allowing the user's limbs to rest against the first bed board 6. At the same time, the telescopic cylinder 14 in the second storage slot 10 is activated, which can raise or lower the second bed board 9. When the second bed board 9 is raised and the first bed board 6 is rotated downwards, the bed can be folded into a sofa, allowing the user to sit on the third bed board 11. When the second bed board 9 is lowered and the first bed board 6 is raised upwards, the bed can be returned to its folded state, allowing the user to lie on the bed.

[0038] Furthermore, a movable plate 5 is installed at the bottom of the support platform 3, and a slide rail 4 is installed on the bottom inner wall of the first storage slot 2. The support platform 3 is slidably installed on the slide rail 4 through the movable plate 5, and the length of the support platform 3 matches the length of the first bed board 6.

[0039] Among them, such as Figures 1-6As shown, the tops of the first bed board 6, the second bed board 9, and the third bed board 11 are each equipped with several inflatable bladders 8 arranged at equal intervals. The bottom inner wall of the inflatable bladder 8 is provided with a second groove 30. The interiors of the first bed board 6, the second bed board 9, and the third bed board 11 are each provided with a gas channel 19. The air outlet of the air pump 24 is connected to a first pipe 15. The interior of the gas channel 19 is equipped with a solenoid valve assembly 20. The air outlet of the solenoid valve assembly 20 is connected to several second pipes 21. Each second pipe 21 passes through the gas channel 19 and is connected to the interior of the second groove 30 of each inflatable bladder 8.

[0040] In this embodiment, several equidistantly arranged airbags 8 are installed on the top of the first bed board 6, the second bed board 9, and the third bed board 11 to form an airbag array. By activating the air pump 24, gas is input into the solenoid valve group 20 through the first tube 15. The solenoid valve group 20 controls the input gas to enter different airbags 8 through the second tube 21. When the airbags 8 inflate, the firmness of the bed can be changed. The degree of inflation of the airbags 8 can be adjusted according to the user's needs for the firmness of the bed, thereby improving the comfort of the bed.

[0041] Among them, such as Figure 2 and Figure 9 As shown, an air inlet box 12 is installed at the bottom of the second bed board 9. An electric heating grid 37 is installed inside the air inlet box 12. A primary filter 39 is embedded on one side of the air inlet box 12. The air inlet of the air pump 24 is connected to an air inlet pipe 23. The end of the air inlet pipe 23 away from the air pump 24 is connected to the inside of the air inlet box 12. A temperature sensor 40 is installed on the inner wall of the air inlet box 12.

[0042] In this embodiment, during the inflation process, the airbag 8 can heat the air inside the air inlet box 12 by activating the electric heating grid 37. The air pump 24 can draw the heated gas inside the air inlet box 12 through the air inlet pipe 23 and input it into the airbag 8, so that the airbag 8 can have a heating effect while being inflated, further improving the comfort of the bed.

[0043] Furthermore, two high-efficiency filters 38 are symmetrically installed inside the air intake box 12. The high-efficiency filters 38 can intercept fine particles or dust, preventing external dust from entering the air intake pipe 23 through the air intake box 12.

[0044] Among them, such as Figures 3-8As shown, a leather layer 18 is installed on the top of the airbag 8, and several ventilation holes are distributed on the leather layer 18. A shell 28 is embedded in the inner wall of the top of the airbag 8. Two sealing plates 32 are symmetrically hinged to the inner wall of the shell 28. Two torsion springs 36 are symmetrically fixed to the inner wall of the shell 28. One end of the torsion spring 36 is fixedly connected to the bottom of the sealing plate 32. A through hole is provided at the bottom of the shell 28. A first magnetic plate 31 is fixedly connected to the inner wall of the second groove 30. A second magnetic plate 33 is fixedly connected to the outer wall of the shell 28. The width and length of the shell 28 are both smaller than the width and length of the second groove 30. A pressure sensor 29 is installed on the bottom inner wall of the second groove 30.

[0045] In this embodiment, when the airbag 8 is not inflated, the user can also use the second magnetic plate 33 and the first magnetic plate 31 to attract the shell 28 in the airbag 8 into the second groove 30, so that the end of the second tube 21 is placed inside the shell 28. When the air pump 24 draws air through the first tube 15, the end of the second tube 21 can generate negative pressure inside the shell 28, causing the sealing plate 32 inside the shell 28 to open downwards, so that external gas can enter the airbag 8 through the vent holes on the leather layer 18. Thus, when the user's body is attached to the leather layer 18, the hot airflow of the body contact area can be drawn away, which plays a role in ventilation and heat dissipation.

[0046] In another embodiment, by extending a connecting hose through the air outlet of the valve body of the solenoid valve assembly 20, with the end of the hose away from the valve body connected to the inside of the housing 28, the air pump 24 can simultaneously pump air out of the leather layer 18 when the airbag 8 is inflated.

[0047] Specifically, two baffles 34 are symmetrically installed on the inner walls of both sides of the housing 28. The baffles 34 are located on the top of the sealing plate 32. A baffle 35 is installed on the top of the housing 28. When the two sealing plates 32 rotate upward, they abut against the bottom of the baffle 35. When the sealing plates 32 rotate upward, they can be restricted by the baffles 34 to prevent the sealing plates 32 from opening upward and causing gas to leak towards the leather layer 18.

[0048] Among them, such as Figures 6-9 As shown, a microcontroller 22 is installed on the inner wall of the first groove 25. The control output terminal of the microcontroller 22 is connected to the electrical control terminals of the motor 26, the telescopic cylinder 14, the air pump 24 and the solenoid valve group 20 respectively through wires. The signal output terminals of the pressure sensor 29 and the temperature sensor 40 are both connected to the signal input terminal of the microcontroller 22.

[0049] It should be noted that when a human body contacts and presses the array of inflatable bladders 8, the inflatable bladder 8 that is contacted can cause the housing 28 to press down the pressure sensor 29. After receiving the pressure sensing signal, the microcontroller 22 can control the solenoid valve group 20 to individually input or output gas to the contacted inflatable bladder 8. The microcontroller 22 can also receive the sensing signal from the temperature sensor 40 and control the operation of the electric heating grid 37 according to the preset program. This allows the present invention to intelligently sense the location of the human body and control the expansion and ventilation of the inflatable bladder 8, while also controlling the degree of heating according to the temperature.

[0050] Specifically, the top of the outer frame 1 of the bed is hinged with a side panel 7, which can protect the side of the human body in the bed.

[0051] Specifically, a limiting block 16 is fixedly connected to one end of the rack 17, and the limiting block 16 can prevent the rack 17 from moving out of the gear 27.

[0052] Specifically, a telescopic rod 13 is hinged to the bottom of the second bed board 9. One end of the telescopic rod 13 is hinged to the bottom inner wall of the second storage groove 10. The telescopic rod 13 can rise and fall with the second bed board 9, playing a certain supporting and stabilizing role.

[0053] In this embodiment, the solenoid valve assembly 20 is a 4V210 solenoid valve module.

[0054] In this embodiment, the air pump 24 is a VRP1000X reversible electric pump.

[0055] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0056] In practical applications, the motor 26 drives the gear 27 to mesh with the rack 17 on one side of the support platform 3, allowing the support platform 3 to move in and out of the first storage slot 2. When the support platform 3 moves out, the first bed board 6 can be raised to the top of the platform, allowing the user to rest their limbs on the first bed board 6. When the support platform 3 moves in, the first bed board 6 can be rotated downwards to the side of the bed frame 1 of the support platform 3, allowing the user to rest their limbs on the first bed board 6. At the same time, the telescopic cylinder 14 in the second storage slot 10 is activated, which can raise or lower the second bed board 9. When the second bed board 9 is raised and the first bed board 6 is rotated downwards, the bed can be folded into a sofa for the user to sit on. When the second bed board 9 is lowered and the first bed board 6 is raised upwards, the bed can be returned to its folded state for the user to lie on. This invention can switch between the bed and sofa states by changing the shape of the first bed board 6 and the second bed board 9.

[0057] In this invention, several equidistantly arranged airbags 8 are installed on the top of the first bed board 6, the second bed board 9, and the third bed board 11, forming an airbag array. By activating the air pump 24, gas is input into the solenoid valve group 20 through the first pipe 15. The solenoid valve group 20 controls the input gas to enter different airbags 8 through the second pipe 21. When the airbags 8 inflate, the firmness of the bed can be changed. The degree of inflation of the airbags 8 can be adjusted according to the user's preference for the firmness of the bed, thereby improving the comfort of the bed. During the inflation of the airbags 8, the air inside the air inlet box 12 can be heated by activating the electric heating grid 37. The air pump 24 can draw the heated gas from the air inlet box 12 through the air inlet pipe 23 and input it into the airbags 8, so that the airbags 8 can have a heating effect while inflating, further improving the comfort of the bed, especially in winter.

[0058] In this invention, the user can also attach the shell 28 of the inflatable bladder 8 to the second groove 30 using the second magnetic plate 33 and the first magnetic plate 31, so that the end of the second tube 21 is placed inside the shell 28. When the air pump 24 draws air through the first tube 15, the end of the second tube 21 can generate negative pressure inside the shell 28, causing the sealing plate 32 inside the shell 28 to open downwards, allowing external gas to enter the inflatable bladder 8 through the vent holes on the leather layer 18. Thus, when the user's body is in contact with the leather layer 18, the hot airflow of the body contact area can be drawn away, playing a role in ventilation and heat dissipation, improving the comfort of the bed in hot summer weather. During the use of this invention, when the human body touches and presses the array of inflatable bladders 8, the contacted inflatable bladder 8 can cause the shell 28 to press down the pressure sensor 29. After receiving the pressure sensing signal, the microcontroller 22 can control the solenoid valve group 20 to individually input or output gas to the contacted inflatable bladder 8, so that this invention can intelligently sense the location of the human body and control the expansion and ventilation and heat dissipation of the inflatable bladder 8.

[0059] Through the above specific embodiments, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
