Description

Technical Field

[0001] This invention relates to the field of nursing pillow technology, specifically to a multifunctional airbag nursing pillow. Background Technology

[0002] Prolonged periods of working with your head down or standing up can cause pain in your head or back. There are already quite a few health care products for the head or back, such as nursing pillows. These nursing pillows are usually filled with cotton or have inflatable air bladders. Elderly patients need long-term care due to the decline in their physical functions.

[0003] Commonly used cotton-filled pillows are usually bulky and inconvenient to carry, while inflatable airbag pillows are more portable, but the inflation and deflation process is more cumbersome. Existing airbag and cotton-filled pillows have relatively simple structures and functions, and can only rely on patients to receive care at fixed points, usually lying in bed or sitting on a sofa. They have poor mobility, and when the patients being cared for have travel needs, especially for elderly patients who require long-term care, they cannot receive care anytime and anywhere.

They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the invention.

[0020] refer to Figures 1 to 8 A multifunctional airbag nursing pillow includes a seat plate 6, a U-shaped mounting bracket 1, a first connecting rod 7, a rectangular block 12, a horizontal mounting rod 3, a mounting frame 14, an armrest 8, a back airbag pillow 5, an L-shaped support rod 13, a neck airbag pillow 4, a flipping mechanism, a first movable mechanism, a second movable mechanism, an inflation mechanism, and a drive mechanism. A seat plate 6 is movably installed on the front side of the horizontal plate of the U-shaped mounting bracket 1. The seat plate 6 is driven to flip by a flipping mechanism. The seat plate 6 can be flipped up and down under the drive of the flipping mechanism. When the seat plate 6 is flipped down to the limit position, it is parallel to the horizontal plane, which is convenient for supporting the user's torso. When the seat plate 6 is flipped up to the limit position, it is perpendicular to the horizontal plane, which reduces the floor space and makes it convenient for storage. Armrests 8 are movably installed on both sides of the seat plate 6. Both armrests 8 are driven to move by the first moving mechanism. The two armrests 8 start to move with the first moving mechanism. Whenever the seat plate 6 is flipped down to be parallel to the horizontal plane, the two armrests 8 also move down and eventually become parallel to the seat plate 6, so as to support the user's elbows after the user sits on the seat plate 6. The first active mechanism is driven to work by the flipping mechanism; The first end of the first connecting rod 7 is installed at an angle at the rear end of the two handrails 8. A rectangular block 12 is fixedly installed on the front wall of the two first connecting rods 7. The vertical rod of the L-shaped support rod 13 is movably installed in the two rectangular blocks 12 respectively. The L-shaped support rod 13 is used to extend out when the seat plate 6 is flipped upward and support the ground, so as to provide a fixed support point for the bottom of the folded equipment and prevent it from tipping over. Both L-shaped support rods 13 are driven to move by the second movable mechanism, and the second movable mechanism is driven to work by the first movable mechanism; A mounting frame 14 is fixedly installed between the two vertical bars of the U-shaped mounting bracket 1. A back airbag pillow 5 is fixedly installed on the front wall of the mounting frame 14. The back airbag pillow 5 is installed on the front side of the two vertical bars of the U-shaped mounting bracket 1. The back airbag pillow 5 is inflated and deflated by a drive mechanism. After the drive mechanism drives the flipping mechanism to flip the seat 6 downward to be parallel to the horizontal plane, the back airbag pillow 5 can be inflated and supported by continuous drive, so that the user can sit on the seat 6 and provide flexible support for the user's back, thus playing a role in back care. The tilting mechanism is driven by the drive mechanism. The same horizontal mounting rod 3 is movably mounted above the two vertical rods of the U-shaped mounting bracket 1. The horizontal mounting rod 3 is driven to move by the flipping mechanism. A neck airbag pillow 4 is installed above the back airbag pillow 5. The neck airbag pillow 4 is inflated and deflated by an inflation mechanism. The horizontal mounting rod 3 drives the inflation mechanism to work. The inflation mechanism is driven by the movement of the horizontal mounting rod 3. When the horizontal mounting rod 3 moves downward, it inflates the neck airbag pillow 4. When the seat plate 6 is completely flipped downward to be parallel to the ground, the horizontal mounting rod 3 also moves downward to its limit position. At this time, the neck airbag pillow 5 will be inflated until it is full due to the downward movement of the horizontal mounting rod 3, providing support and care for the user's neck.

[0021] The flipping mechanism includes a first rectangular slider 201, a vertical movable rod 2, a second connecting rod 10, a first connecting plate 601, and a second connecting plate 102; The two ends of the rear wall of the seat plate 6 are respectively fixedly installed with first connecting plates 601, and the lower ends of the two vertical rods of the U-shaped mounting bracket 1 are respectively fixedly installed with second connecting plates 102. The two first connecting plates 601 are respectively hinged to the second connecting plates 102 that are close to them. The two vertical rods of the U-shaped mounting bracket 1 are each provided with a first rectangular through hole 103. A vertical movable rod 2 is slidably installed in each of the two first rectangular through holes 103. A horizontal mounting rod 3 is fixedly installed on the top wall of the two vertical movable rods 2. The two vertical rods of the U-shaped mounting bracket 1 are each provided with a first rectangular through groove 101, and the two first rectangular through grooves 101 are respectively connected to the first rectangular through hole 103 that is close to them. Two vertical movable rods 2 are respectively fixedly installed on the outer walls of the two rectangular sliders 2, and the two first rectangular sliders 201 are slidably connected through the first rectangular through groove 101 that is close to them. Two first rectangular sliders 201 are respectively fixedly installed on the outer walls of the two first connecting shafts, and the first ends of the second connecting rods 10 are respectively rotatably sleeved on the outer walls of the two first connecting shafts. The middle sections of the two side walls of the seat plate 6 are respectively fixedly installed with second connecting shafts, and the middle ends of the two second connecting rods 10 are respectively rotatably sleeved on the outer wall of the second connecting shafts that are close to them. The two second links 10 respectively drive the first movable mechanism to work through deflection; Both first rectangular sliders 201 are driven to slide by the drive mechanism, see reference. Figure 3 Driven by the driven mechanism, the two first rectangular sliders 201 move up and down along the first rectangular through slot 101 adjacent to them. When the two first rectangular sliders 201 move downward, they will drive the second connecting rods 10 adjacent to them to deflect downward. The two second connecting rods 10 together drive the seat plate 6 to move downward. Since the rotation center of the seat plate 6 is determined, the two second connecting rods 10 will simultaneously drive the seat plate 6 to make a circular motion downward around its own rotation center during the downward deflection. When the two first rectangular sliders 201 slide downward to the limit position, they will contact the bottom wall of the first rectangular through slot 101 adjacent to them. At this time, the seat plate 6 is just flipped to a state parallel to the horizontal plane. When the two first rectangular sliders 201 slide upward to the limit position, they will contact the top wall of the first rectangular through slot 101 adjacent to them. At this time, the seat plate 6 is just flipped upward to a state perpendicular to the horizontal plane, which greatly reduces the floor space and makes it easy to store.

[0022] The first movable mechanism includes a second rectangular slider 19, a second rectangular through slot 1001, and a third connecting shaft; The upper middle ends of the two second connecting rods 10 are respectively provided with second rectangular through slots 1001, and the two first connecting rods 7 are movably installed in the second rectangular through slots 1001 that are close to them; The two sidewalls of the two second rectangular through slots 1001 are fixedly connected by a third connecting shaft; The two third connecting shafts are respectively rotatably connected between the middle end of the first connecting rod 7 that is close to them; A fourth connecting shaft is fixedly installed on the outer wall of each of the two second connecting plates 102, and a second rectangular slider 19 is rotatably sleeved on the outer wall of each of the two fourth connecting shafts. The inner walls of the two first connecting rods 7 are respectively provided with rectangular sliding grooves 701, and the two second rectangular sliders 19 are respectively slidably installed in the rectangular sliding grooves 701 that are close to them. Both first linkages 7 drive the second movable mechanism through deflection. (Refer to...) Figure 2 When the two second links 10 rotate downwards, they will respectively drive the adjacent first link 7 to move downwards. (Refer to...) Figure 5 During the downward movement of the two first connecting rods 7, the adjacent second rectangular sliders 19 are forced to slide along the rectangular grooves 701. The two second rectangular sliders 19, by moving within the adjacent rectangular grooves 701, respectively limit the movement trajectory of the two first connecting rods 7. When the two second connecting rods 10 deflect downward and simultaneously rotate the seat plate 6 downward to be parallel to the horizontal plane, the two second rectangular sliders 19 will move upward along the adjacent rectangular grooves 701. At this time, the two first connecting rods 7 will respectively drive the two armrests 8 downward and eventually move to a position parallel to the seat plate 6. When the two second connecting rods 10 deflect upward and simultaneously rotate the seat plate 6 upward to be perpendicular to the horizontal plane, the two second rectangular sliders 19 will respectively move downward along the adjacent rectangular grooves 701. During the downward movement of the two second rectangular sliders 19, the two first connecting rods 7 will respectively drive the fixed armrests 8 upward and eventually achieve storage. In the stored state, the two first connecting rods 7 are perpendicular to the horizontal plane, reducing the floor space occupied.

[0023] The second moving mechanism includes a third link 11, a first connecting frame 1002, and a second connecting frame 1301; The lower middle parts of the two second connecting rods 10 are respectively fixedly installed with first connecting brackets 1002, and the first end of the third connecting rod 11 is rotatably installed in the two first connecting brackets 1002 respectively; Two rectangular blocks 12 are respectively installed with second rectangular through holes on their bottom walls. The vertical rods of two L-shaped support rods 13 are respectively slidably installed in the second rectangular through holes close to them. The horizontal rods of two L-shaped support rods 13 are respectively movably installed below the rectangular blocks 12 close to them. The front walls of the two rectangular blocks 12 are respectively provided with third rectangular through slots 1201, and the two third rectangular through slots 1201 are respectively connected to the second rectangular through holes adjacent to them. The two L-shaped support rods 13 have a second connecting bracket 1301 fixedly installed on the middle part of the front wall of the vertical rod; The two second connecting brackets 1301 are slidably connected through the third rectangular through slot 1201 adjacent to them; The second ends of the two third links 11 are respectively rotatably mounted in the adjacent second connecting bracket 1301, for reference. Figure 6 As the two first links 7 and the two second links 10 move upward, the angle between the first link 7 on the same side and the second link 10 that is close to it will begin to decrease. The second link 10 will move closer to the first link 7, and in the process of moving closer, it will drive the third link 11 to deflect downward. As the two third links 11 deflect downward, they will push the second connecting frame 1301 that is close to them to move downward. The L-shaped support rods 13 that are fixedly installed with the two second connecting frames 1301 will then begin to slide downward. When the two first links 7 and the two second links 10 move upward to their limit positions, the seat plate 6 and the first links 7 on both sides are in the retracted state. At this time, the crossbars of the two L-shaped support rods 13 contact the ground to support the equipment, which improves the stability of the equipment in the retracted state.

[0024] First rollers 9 are rotatably mounted on the lower outer walls of the two first connecting rods 7 respectively; Two second rollers 901 are rotatably mounted on the lower outer walls of the two second connecting rods 10. When the seat plate 6 is parallel to the ground, the two first rollers 9 and the two second rollers 901 will contact the ground and support the device. At this time, the device is in wheelchair mode. The user can sit on the seat plate 6 and receive back and neck care while meeting the mobility needs. When the seat plate 6 is flipped up for storage, the two first rollers 9 will approach each other but not contact the adjacent second rollers 901. The two downward-extending L-shaped support rods 13 will then replace the two first rollers 9 and the two second rollers 901 to support the ground.

[0025] The driving mechanism is an air pump 20; The air pump 20 is fixedly installed on the rear wall of one of the vertical rod ends of the U-shaped mounting bracket 1; A first air inlet 1011 is provided on the top wall of the first rectangular through groove 101 that is close to the air pump 20; The output end of the air pump 20 is connected between the vertical rod of the U-shaped mounting bracket 1 and the first air inlet 1011. The first rectangular slider 201 located below the first air inlet 1011 is in detachable contact with the first air inlet 1011; A second air inlet 1012 is provided on the lower side of the front wall of the first rectangular through groove 101 located on the same side as the first air inlet 1011; The second air inlet 1012 is connected to the back airbag pillow 5; A first rectangular slider 201, which is close to the second air inlet 1012, is detachably and movablely installed below the second air inlet 1012; The top and bottom walls of the two first rectangular sliders 201 are connected to the top and bottom walls of the adjacent first rectangular through slots 101 via telescopic baffles, respectively. (Refer to...) Figure 7 When the air pump 20 is activated, its output begins to inflate the first rectangular channel 101 adjacent to it. The first rectangular slider 201 within the channel 101, under external air pressure, begins to move downwards. Because the slider 201 is connected to the top and bottom walls of the channel 101 via telescopic baffles during its movement, the gas remains within the channel 101 without leakage. When the slider 201 is pressed against the bottom wall of the channel 101 by the air pressure, the second air inlet 1012 is exposed. The air pump 20 continues to inflate, and additional gas enters the back airbag pillow 5 through the second air inlet 1012, thus inflating the back airbag pillow 5. When stored, the air pump 20... When the air is pumped out, the gas inside the back airbag pillow 5 is first discharged through the second air inlet 1012. When there is no more gas inside the back airbag pillow 5, the air pump 20 starts to pump the first rectangular slider 201 that is close to it. Since the vertical movable rod 2 is movably installed in the first rectangular through hole 103 and the vertical movable rod 2 and the first rectangular through hole 103 are sealed and slide together, and the first rectangular through hole 103 is a vertical rod that passes through the U-shaped mounting bracket 1, a negative pressure is formed in the first rectangular through groove 101 during the process of the air pump 20 pumping the first rectangular slider 201, which begins to push the first rectangular slider 201 upward. After the first rectangular slider 201 slides to the top, the air pump 20 is operated to stop pumping, so that the first rectangular slider 201 that is close to it is fixed at the top.

[0026] The inflation mechanism includes a fixed tube 16, a first connecting tube 17, a second connecting tube 18, and a movable rod 15; Two movable rods 15 are fixedly installed at the lower end of the horizontal mounting plate 3, and the two movable rods 15 are installed between the two vertical movable rods 2; Two fixed tubes 16 that cooperate with the movable rod 15 are fixedly installed through the top wall of the mounting frame 14; The lower ends of the two fixed tubes 16 are connected by a first connecting tube 17; The two movable rods 15 are respectively sealed and slidably installed in the fixed tube 16 adjacent to them; The middle end of the first connecting pipe 17 is connected to the first end of the second connecting pipe 18, and the second end of the second connecting pipe 18 is connected to the neck airbag pillow 4. (Refer to...) Figure 4 Two vertical movable rods 2 move up and down with the first rectangular slider 201 fixed thereto, and during the movement, they also drive the horizontal mounting plate 3 fixed thereto to move up and down. When the horizontal mounting plate 3 moves downward, it will drive the two movable rods 15 downward. During the downward movement of the two movable rods 15, they will pressurize and inflate the two fixed tubes 6 respectively. The air pressure in the fixed tubes 6 will enter the neck airbag pillow 4 through the first connecting tube 17 and the second connecting tube 18 respectively to inflate the neck airbag pillow 4. When the horizontal mounting plate 3 drives the two movable rods 15 upward, it will suck in the neck airbag pillow 4. When the horizontal mounting plate 3 moves upward to the limit position, the air in the neck airbag pillow 4 will be completely sucked in and finally deflate.

[0027] Implementation method of the present invention: Place this device on a horizontal surface. The device should be in its initial state as follows: Figure 8 As shown in B, the seat plate 6 flips upward and is stored, and the two second connecting rods 10 respectively drive the armrests 8 fixed to it to be stored upward. The horizontal mounting plate 3 is at the top at this time, and the neck airbag pillow 4 and the back airbag pillow 5 are both in the state of being ready to be inflated. The two L-shaped support rods 13 are in contact with the ground and support the equipment. When the equipment is needed, the air pump 20 is started. The output end of the air pump 20 begins to inflate the first rectangular through slot 101 that is close to it. The first rectangular slider 201 located in the first rectangular through slot 101 begins to move downward. As the first rectangular sliders 201 on both sides move downward, the seat plate 6 begins to gradually rotate downward around its own rotation center and finally flips downward to a state parallel to the ground. The two second connecting rods 10 respectively drive the handrails 8 that are fixed to them to move downward and finally move to a state parallel to the seat plate 6. The two L-shaped support rods 13 then begin to retract upward. The two first rollers 9 and the two second rollers 901 unfold under the drive of the two first connecting rods 7 and the two second connecting rods 10 respectively and replace the two L-shaped support rods 13 to support the ground. When the first rectangular slider 201, which is close to the air pump 20, slides to the bottom of the first rectangular through slot 101, the second air inlet 1012 will be exposed. Additional gas will enter the back airbag pillow 5 through the second air inlet 1012 and inflate it. As the first rectangular sliders 201 on both sides slide to their lowest positions, the two vertical movable rods 2 move downwards simultaneously, causing the horizontal mounting rod 3 to move downwards as well. As the horizontal mounting rod 3 moves downwards, it inflates the neck airbag pillow 4, eventually filling it completely. At this point, the device... Figure 8In the state shown in Figure A, the user can sit on the seat 6 with their elbows on the armrests 8 on both sides, their back against the front of the inflated back airbag pillow 5, and their neck against the inflated neck airbag pillow 4, thus achieving the effect of simultaneous care during movement.

[0028] The seat of this invention can be lowered or folded upwards by the flipping mechanism. When the seat is flipped downwards to a horizontal position, the armrests on both sides can simultaneously be flipped downwards to be flush with the seat by the first moving mechanism, so that the user's elbows can be supported when sitting. After the driving mechanism drives the flipping mechanism to flip the seat downwards to be parallel to the ground, the driving mechanism of this invention can inflate the back airbag pillow by continuing to drive. When the back airbag pillow is inflated, it can provide flexible support for the user's back. The inflation mechanism of this invention can inflate the neck airbag pillow after the seat is flipped downwards to be parallel to the ground, so that the neck airbag pillow can support the user's neck and provide neck care. Because this invention combines the back airbag pillow and the neck airbag pillow with the wheelchair, it has strong mobility and can meet the user's needs for mobility while receiving back and neck care. When the device is stored, the footprint is reduced, making it convenient to store.
