[0031] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with specific implementation methods and drawings.
[0032] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.
[0033] Reference Figure 1-2 , this embodiment provides an anti-dumping inflatable assisting seat cushion, including an assisting assembly 1, including a soft bag 11 and a supporting member 12 disposed inside the soft bag 11;
[0034] The support member 12 includes a fabric body pressure sensing pad 121 that is in contact with the inner wall of the soft bag 11, a heightening pad 122 disposed below the fabric body pressure sensing pad 121, a base pad 123 disposed below the heightening pad 122, and a correction pad 124 disposed between the fabric body pressure sensing pad 121 and the heightening pad 122 for correcting the user's tilt. The correction pad 124 includes a plurality of airbag groups for correcting the user's tilt.
[0035] Furthermore, the material of the soft bag 11 is Oxford fiber fabric with a thickness of 1.8 mm and has excellent properties such as high strength, high modulus, high temperature resistance, acid and alkali resistance, light weight, insulation, anti-aging, and long life cycle.
[0036] Preferably, the fabric body pressure sensing pad 121 can collect the body pressure distribution data of the user's contact surface with the seat cushion in real time. Its surface is covered with a high-opening-rate sponge and has good air permeability. Its upper surface is bonded to the inner surface of the outer soft bag (the bonding line is a uniformly distributed grid with a mesh size of 50x50mm and a mesh width of 2mm), which can meet the need to limit its displacement, save materials, and not affect the folding and storage of the entire seat cushion after deflation and the acquisition of body pressure data.
[0037] Preferably, both the height-enhancing cushion 122 and the correction cushion 124 are wedge-shaped airbag cushions, and their volumes after being fully inflated are based on the user, and gradually increase toward the side away from the user. When the height-enhancing cushion 122 is inflated, the overall height of the seat cushion can be changed to assist the user in getting up.
[0038] Preferably, the thickness of the bottom pad 123 after inflation is 30mm±3mm, and the material of the bottom pad 123 and all the air cushions in the support are TPU composite cloth, which has the advantages of good support, high air tightness, anti-aging, toughness, wear resistance, etc., and the bottom pad 123 is made of two layers of the same material through ultrasonic welding, which has the advantages of environmental protection and high efficiency, high degree of automation, high precision, good firmness, smooth and beautiful seams, etc.
[0039] The height-enhancing cushion 122 and the correction cushion 124 are both wedge-shaped after being inflated, and the height-enhancing cushion 122 has only one chamber, which only plays a role in changing the angle and height of the seat surface, and does not have a sitting posture correction effect.
[0040] The height of the tail of the height-increasing cushion 122 and the correction cushion 124 after inflation is 115 mm ± 10 mm, and both of them can provide an assisting tilt angle of 18° ± 2°.
[0041] In summary, the cushion has at least the following two forms when in use:
[0042] The first type: only the bottom cushion 123 is inflated to a predetermined inflation amount. At this time, it functions as an ordinary soft cushion with moderate hardness, reasonable user body pressure distribution, good comfort, and isolation from dirt from outdoor sitting areas, as well as from temperatures unsuitable for human bodies or uneven seat surfaces.
[0043] The second method: when the user needs to realize the assist function, the height-enhancing cushion 122 is inflated, and the user's posture at this time is detected by the fabric body pressure sensing pad 121 to detect whether the user is in a stable elevated state at this time. If the user is in a stable state at this time, that is, the pressures detected in various places in the fabric body pressure sensing pad 121 are within the preset range, the height-enhancing cushion 122 continues to be inflated until the user is assisted to stand up completely; if the fabric body pressure sensing pad 121 detects that the pressure at a certain place is higher than the set threshold at this time, the airbag on the larger pressure side of the correction pad 124 is inflated to adjust the user's posture to a stable state to prevent the user from falling from the seat cushion.
[0044] As an optional embodiment, refer to Figure 1 to Figure 3 The present embodiment provides an anti-dumping inflatable seat-assisting cushion, comprising a soft bag 11 including a first side surround 111, a second side surround 112, and a baffle 113 arranged between the first side surround 111 and the second side surround 112; wherein, a wire entry hole 114 is provided at the bottom of the baffle 113, and the first side surround 111, the second side surround 112 and the baffle 113 can all be folded.
[0045] The enclosure 113 is fixedly connected to part of the side lines of the first side enclosure 111 and the second side enclosure 112, and can be connected by sewing, welding, etc., and is not detachable. At least two side lines are retained for detachable connection, and can be connected by zippers, so as to facilitate disassembly in case of failure to check the internal situation.
[0046] The side of the enclosure 113 that contacts the ground or does not contact the user's buttocks is provided with rubber particles to enhance its anti-slip performance.
[0047] A machine indentation is provided on one side of the enclosure 113 away from the user, so as to facilitate folding after deflation.
[0048] The first side enclosure 111 and the second side enclosure 112 are provided with machine indentations on one side away from the support member 12 to facilitate the folding of the air cushions in the support member 12 after they are deflated.
[0049] A wire entry hole 114 is provided on one side of the enclosure 113 away from the user, for connecting the air cushions in the support member 12 with the inflation tube and the data transmission line group.
[0050] As an optional embodiment, refer to Figure 1 to Figure 4 This embodiment provides an anti-dumping inflatable sit-up aid cushion, including a correction cushion 124 whose inner space increases gradually from the user's side to the side away from the user.
[0051] The correction cushion 124 and the height-enhancing cushion 122 have the same shape. When the correction cushion 124 and the height-enhancing cushion 122 are fully inflated, both are wedge-shaped air cushions, that is, the smaller side of the correction cushion 124 and the height-enhancing cushion 122 faces the user, thereby changing the height and angle of the seat surface.
[0052] As an optional embodiment, refer to Figure 1 to Figure 4 The present embodiment provides an anti-tilt inflatable sit-up cushion, including a correction cushion 124 including a first anti-tilt airbag L, a second anti-tilt airbag M and a third anti-tilt airbag R for correcting different tipping positions, and each anti-tilt airbag is provided with a connecting rib 1241.
[0053] A partition film is provided inside the correction pad 124 for separating the inflation chambers. The correction pad 124 is divided into three inflation chambers by the partition film, namely, the first anti-roll airbag L, the second anti-roll airbag M and the third anti-roll airbag R. The partition film is connected by ultrasonic welding, and the weld 1-2-6 is 5 mm wide.
[0054] The first anti-roll airbag L, the second anti-roll airbag M and the third anti-roll airbag R correspond to the left support airbag, the middle support airbag and the right support airbag respectively.
[0055] Through experiments, it is known that as the human body tilts to one side, the difference between the left and right sides is as follows:
[0056]
[0057] The TPU composite material forms an airbag after inflation. The deformation caused by the pressure on the airbag is mainly caused by the compressed gas, while the TPU material itself will not deform. When the bottom pad 123 with a height of 3mm is filled with an initial air pressure of 50kPa: when a person weighing 80kg sits on it, the height of the airbag is reduced to about 2.77cm (height change of 7.7%).
[0058] 40 kPa initial air pressure: the airbag height is reduced to 2.71 cm (8.7%) (the initial air pressure of the bottom cushion 123 is selected to be 40 kPa, and the deformation is controlled to be less than 10% to save costs while eliminating the risk of rollover).
[0059] 30 kPa initial air pressure: the balloon height decreased to 2.61 cm (13%).
[0060] 20 kPa initial air pressure: the balloon height decreased to 2.42 cm (19%).
[0061] Both the correction pad 124 and the height-increasing pad 122 are made of TPU material. Due to the characteristics of TPU material, it will basically not deform. As long as the internal air pressure reaches a certain value, people sitting on it will not deform. However, during the inflation process, before the air pressure reaches the target value, external influences will significantly affect the shape of the airbag. Take the previous base pad 123 as an example, because its height when fully inflated is only 3 cm, even if it tilts, it is only 3 cm, which will not be serious enough to cause a person to fall. If this height is smaller, the impact on people will be smaller. So assuming that this height is 10 cm now, it is easy for people to tilt during inflation.
[0062] The purpose of the heightening pad 122 is mainly to change the seat inclination angle, so it cannot be set very thin, so the heightening pad 122 is prone to tilting. Therefore, the present invention adopts a partition control method to solve the tilting problem. At the same time, the wedge-shaped heightening pad 122 and the correction pad 124 are used to reduce the volume of the airbag cavity, making it more convenient to control the tilting.
[0063] In summary, when the user uses the sitting-assist cushion, the data detected by the fabric body pressure sensor pad 121 is compared with the original threshold value. If the pressure on one side of the first anti-tilt airbag L is significantly higher than the threshold value, it means that the user is obviously leaning toward the first anti-tilt airbag L. The first anti-tilt airbag L is inflated according to the difference between the measured value and the threshold value to correct the user's state to a stable state and prevent the user from tilting.
[0064] As an optional embodiment, refer to Figure 5 This embodiment provides an anti-tipping inflatable seat-assisting cushion, including a connecting rib 1241 centrally arranged in each anti-tipping airbag, the length of the connecting rib 1241 increases gradually toward the side away from the user based on the user side, and the width of the connecting rib 1241 is proportional to the width of the anti-tipping airbag.
[0065] The specific parameters of the correction pad 124 or the heightening pad 123 are as follows Figure 5 As shown, Figure 5The unit is centimeter (cm), wherein the overall width of the connecting rib 1241 is 10 cm when the width of the correction pad 124 is 44 cm, to ensure that the correction pad 124 or the height-increasing pad 123 remains flat on one side with a larger surface area when it is inflated.
[0066] Taking the control group without using the lifting aid, the muscle activity and stability of the leg muscles are optimal when the seat height is 55-60cm and the seat inclination angle is 20-30°, ensuring that the height-enhancing pad 124 can be used optimally for seats with a height of 40cm and above. At the same time, increasing the seat inclination angle will significantly reduce the torque of the knee joint, ankle joint, and hip joint, reducing the joint load.
[0067] As an optional embodiment, refer to Figure 1-2 The present embodiment provides an anti-dumping inflatable sitting-assisting cushion, including a support member 12 and a support airbag 125. The support airbag 125 is located between the correction pad 124 and the fabric body pressure sensing pad 121. The support airbag 125 and the bottom pad 123 are both planar air cushions.
[0068] The thickness of the support airbag 125 after inflation is 30 mm±3 mm, and its material is TPU composite cloth, which is the same as the bottom pad 123 .
[0069] In the present invention, the soft bag 11 is contacted first, with the side close to the user's buttocks as a reference. The first layer of the air cushion in the support member 12 away from the user's buttocks is a fabric body pressure sensing pad 121, the second layer is a supporting airbag 125, the third layer is a correction pad 124, the fourth layer is a heightening pad 122, and the fifth layer is a base pad 123.
[0070] Disposing the correction pad 124 at a position close to the user's side can make the correction pad 124 have a better regulating effect, and can transmit the shape change of the airbag to the human body more quickly and directly.
[0071] The height-increasing cushion 122 is mainly used to change the seat inclination angle. The correction cushion 124 is arranged adjacent to the height-increasing cushion to prevent the seat from changing not only the seat inclination angle but also the seat surface position and the seat height during inflation. The base cushion 123 is mainly used to change the seat height.
[0072] As an alternative embodiment, refer to Figure 6 The present embodiment provides an anti-dumping inflatable sit-up cushion, including a support airbag 125 and a bottom cushion 123, wherein a plurality of welds are arranged inside and around the support airbag 125 and the bottom cushion 123 to connect the two surfaces thereof, and the internal welds are arranged in parallel, and the length of the welds is 5 mm.
[0073] Figure 6The unit is centimeter (cm). In the supporting airbag 125 of the present invention, the length is 50 cm, and 9 welds with a length of 5 mm are parallelly and evenly arranged outside the supporting airbag 125.
[0074] The smaller the width of the weld, the better. The smaller the width, the less material waste. The width of the weld is positively correlated with the strength of the airbag. Experiments have found that a weld length of 5mm can ensure that the air pressure of 100kpa will not rupture, and it also meets common factory processing conditions.
[0075] The welds are evenly distributed. The fewer the welds, the greater the vertical and horizontal deformations of the support airbag 125 after inflation. If no weld exists, the support airbag 125 will be a sphere after inflation. When nine welds are set, the horizontal deformation is less than 10%, which will not affect the seat surface size.
[0076] As an alternative embodiment, refer to Figure 6 to Figure 8 The present embodiment provides an anti-tipping inflatable seat-assisting cushion, including a base pad 123 with an end away from the user fixedly connected to a mounting chamber 1231, a receiving groove 1232 is provided inside the mounting chamber 1231, and an air pipe hole 1233 connected to the receiving groove 1232 is provided on the end surface of the mounting chamber 1231.
[0077] There are multiple air hole tubes 1233, and multiple air tubes are respectively arranged in the multiple air hole tubes 1233 to communicate with each of the above-mentioned air bags.
[0078] Furthermore, Figure 8 The weld seam diagram of the bottom pad 123 is shown in FIG. Figure 6 The length of the base pad 123 of the present invention is 50 cm, and 9 welds with a length of 5 mm are arranged parallel and evenly around the base pad 123.
[0079] As an optional embodiment, refer to Figure 2 The present embodiment provides an anti-dumping inflatable sitting-assisting cushion, including a support member 12 and an isolation layer 126. The isolation layer 126 is provided with a plurality of pieces, and the plurality of isolation layers 126 are located between the soft bag 11 and each layer of the air cushion.
[0080] In the present invention, five isolation layers 126 are provided, which are respectively located between the fabric body pressure sensing pad 121 and the supporting airbag 125 , between the supporting airbag 125 and the correction pad 124 , between the correction pad 124 and the height-increasing pad 122 , between the height-increasing pad 122 and the bottom pad 123 , and between the bottom pad 123 and the enclosure 113 .
[0081] The isolation layer 126 is 0.8 mm thick and is mainly made of Oxford fabric with excellent wear resistance. The isolation layer is connected to the air cushion around it by gluing to control the stability of the entire seat cushion, prevent lateral displacement between the airbags, and increase the service life of each airbag.
[0082] As an optional embodiment, refer to Figure 11-12 This embodiment provides an anti-dumping inflatable sitting-assisting cushion, including a trapezoidal foldable enclosure 113, a fabric body pressure sensing pad 121 is arranged on the waist inner side of the trapezoidal enclosure 113, and a plurality of groups of height-enhancing cushions 122 are arranged, and each group of height-enhancing cushions 122 includes a plurality of airbags. Each group of height-enhancing cushions 122 is fixedly connected by a connecting strip 127, and an isolation pad 126 is arranged between each group of height-enhancing cushions 122, which is consistent with the above-mentioned function, and the isolation pad 126 is used to prevent each group of height-enhancing cushions 122 from sliding against each other and maintaining their stability.
[0083] The height-enhancing pads 122 in this embodiment are in the form of planar airbags. The number of height-enhancing pads 122 is selected according to the required height. Taking this embodiment as an example, three groups of height-enhancing pads 122 are used in this embodiment. The volume of each group of height-enhancing pads 122 gradually decreases as the height increases, and the number of planar airbags between each group of height-enhancing pads 122 increases as the height increases, and the volume of the planar airbags also gradually decreases. That is, the groups of height-enhancing pads 122 are similar in shape, and the planar airbags inside each group of height-enhancing pads 122 are also similar in shape.
[0084] Furthermore, each planar airbag is connected to an air pump pipeline, and the airbags between each group of height-enhancing pads 122 can be inflated and deflated independently.
[0085] In summary, when the user uses it, when a single set of heightening pads 122 is inflated, the daily isolation needs are met. When the user needs to be lifted, multiple sets of heightening pads 122 are inflated; and when the user tilts, according to the user's tilting direction, the inflation rate and strength of the plane airbag in that direction are increased to prevent the user from tilting.
[0086] Reference Figures 9 to 12 The present embodiment provides an inflation system, including an inflation system 2, including an air pump 21, an air pump diversion solenoid valve 22 connected to the air pump 21 and used to divert the gas pumped out by the air pump 21, a main control unit 23 that controls the air pump 21 to inflate different air cushions through the air pump diversion solenoid valve 22, and a power supply 25 that supplies power to each unit in the system.
[0087] As an optional embodiment, refer to Figures 1 to 13The present embodiment provides an inflation system, including a shell 24 disposed below a power source 25, the shell 24 including four baffles 241 rotatably disposed therearound, a handle 242 being disposed on the end surface of the baffle 241 for easy carrying and disassembly, wherein a second air pipe hole 243 and a circuit window 244 are penetrated through the baffle 242 on the side close to the soft bag 11.
[0088] The shell 24 is made of light aluminum alloy, with magnetic buckles at the opening and hinges at the folding seams, and has the advantages of being strong, light, easy to process, and corrosion-resistant. A solar panel is provided inside the shell 24 to convert solar energy into electrical energy for the power source 25.
[0089] The main control unit 23 is fixed on the fixed baffle 241, and its data line group and circuit line group are integrated and aligned on the circuit window 244. The line group can be stretched and twisted within a certain range, and can be connected to the wire entry hole 114 on the enclosure 113 after extending from the circuit window 244.
[0090] The main control unit 23 receives, analyzes and calculates the body pressure data of the fabric body pressure sensing pad 121 , and provides control signal transmission and power energy support for the air pump 21 and the air pump diversion solenoid valve 22 .
[0091] The solar panel inside the baffle 241 is connected to the main control unit 23 to adjust the parameters related to the generated electric energy, and store it in the power supply 25 after rectification.
[0092] The power supply 25 is connected to the main control unit 23, receives and stores the electric energy generated by the solar panel assembly and rectified after adjusting the parameters, and provides the output of electric energy to other related devices after the main control unit 23 adjusts the relevant parameters.
[0093] The air pump 21 is located above the power supply 25. Its gas output pipeline can be expanded and twisted within a certain range. It extends from the second air pipe hole 243 and is connected to the wire inlet hole 114 on the enclosure 113. After receiving the inflation command issued by the main control unit 23, it generates a corresponding amount of gas at a corresponding speed and provides gas to each airbag through the air pump diversion solenoid valve 22.
[0094] In summary, the use of the seat cushion is as follows:
[0095] First, the user unfolds the soft bag 1 and lays it flat on the seat surface, fully unfolds the housing 24, and properly connects the airway pipeline, power supply 25, and signal line pipeline. The device is ready to be used.
[0096] ① The solar panel converts light energy into electrical energy, which is rectified and processed by adjusting relevant parameters through the mainboard component and stored in the power supply 25.
[0097] ②There is a control unit on the front side of the seat cushion, and you can also connect your phone to Bluetooth and use the control unit on the phone to control the seat cushion.
[0098] ③ The user inputs instructions to the mainboard assembly through the control unit to control the air pump assembly and the air pump diversion solenoid valve assembly to inflate the support airbag 125 and the bottom cushion 123 to a predetermined inflation volume. At this time, the function is an ordinary soft seat cushion with moderate hardness, reasonable user body pressure distribution, good comfort, and isolation from dirt from outdoor sitting areas, as well as from temperatures that are unsuitable for the human body or uneven seat surfaces.
[0099] ④ The user inputs instructions to the main control unit 23 through the control unit to control the air pump 21 and the air pump shunt solenoid valve 22 to inflate all air bags in the following order:
[0100] Ⅰ The support airbag 125 is deflated (to meet the data accuracy of the flexible body pressure sensing pad 121).
[0101] Ⅱ The height-enhancing pad 122 is inflated, and the data of the fabric body pressure sensing pad 121 is collected and monitored at the same time.
[0102] III The monitoring data of the fabric body pressure sensing pad 121 has been entered into the main control unit 23 in advance, and its data collection and calculation points are realized by partitioning the thin film pressure sensor, that is, each airbag can collect the pressure data of its corresponding area.
[0103] IV When the data of the fabric body pressure sensor pad 121 exceeds the set threshold, the correction pad 124 is inflated, and the air pump 21 and the air pump diversion solenoid valve assembly 22 are used to control the inflation and deflation volume and inflation and deflation speed of different chambers in the correction pad 124 (the chamber on the side with lower pressure is inflated, and the chamber on the side with higher pressure is deflated). At the same time, the body pressure data is monitored in real time until the data returns to normal standards.
[0104] V. Continue to inflate the height-enhancing cushion 122 and repeat steps II and IV until the inflation amounts of the height-enhancing cushion 122 and the correction cushion 124 reach the preset values.
[0105] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
