[0005] To solve the above-mentioned technical problems, the present invention provides a bed comprising a bed frame, a headrest assembly, a first airbag mechanism, an air source device, and a second airbag mechanism. The bed frame is provided with a first mounting groove, a second mounting groove, and a third mounting groove, which are arranged sequentially along the length of the bed frame. The headrest assembly is disposed in the first mounting groove. The first airbag mechanism is disposed in the second mounting groove. The air source device is disposed in the third mounting groove. The second airbag mechanism comprises a cover plate and an airbag assembly, with the airbag assembly disposed on the cover plate and the second airbag mechanism disposed at the opening of the third mounting groove. The second airbag mechanism is located above the air source device, and the cover plate covers the opening of the third mounting groove. Both the first and second airbag mechanisms are connected to the air source device.

[0006] Optionally, the airbag assembly also includes a mounting plate and an adjustable airbag, the adjustable airbag being disposed on the mounting plate, and a cover plate being disposed on the surface of the mounting plate facing the adjustable airbag; the bed frame is also provided with a receiving groove, a third mounting groove being located at the bottom of the receiving groove, and the mounting plate being received in the receiving groove.

[0007] Optionally, the thickness of the mounting plate is less than the depth of the receiving groove. When the mounting plate is received in the receiving groove, the mounting plate and the bed frame enclose and define the receiving space on the side wall of the receiving groove, and the adjustable airbag is located in the receiving space.

[0008] Optionally, after adjusting the airbag inflation, adjust the airbag so that its back is flush with the top of the mounting plate and the opening of the receiving groove along the height direction of the bed frame.

[0009] Optionally, the cover plate is made of sound-absorbing material.

[0010] Optionally, along the height of the bed frame, the top surface of the air source device is flush with the opening of the third mounting slot, and the cover plate abuts against the air source device.

[0011] Optionally, the bed also includes a support structure, one end of which abuts against the bottom wall of the third mounting groove, and the other end of which abuts against the mounting plate.

[0012] Optionally, the support structure and the sidewalls of the receiving groove enclose and define the third mounting groove; or, the third mounting groove is opened from the top surface of the support structure along the height direction of the bed frame.

[0013] Optionally, the bed frame has a noise-reducing layer on the inner wall of the third mounting slot.

[0014] Optionally, along the height direction of the bed frame, the edge of the projection of the mounting plate at least partially coincides with the edge of the projection of the receiving groove, so that when the mounting plate is set in the receiving groove, the cover plate covers the third mounting groove.

[0015] The beneficial effects of this utility model embodiment are as follows: Unlike existing technologies, this utility model embodiment provides a bed, including a bed frame, a headrest assembly, a first airbag mechanism, an air source device, and a second airbag mechanism.

[0020] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0022] Please see Figure 1 and Figure 2 The bed includes a bed frame 100, a headrest assembly 300, a first airbag mechanism 400, an air source device 200, and a second airbag mechanism 500. The headrest assembly 300, the first airbag mechanism 400, and the second airbag mechanism 500 are sequentially arranged on the bed frame 100 along the length X of the bed. This achieves functional zoning: the headrest assembly 300 supports the user's head, the first airbag mechanism 400 supports the user's torso, and the second airbag mechanism 500 supports the user's feet. The air source device 200 is located below the second airbag mechanism 500, and both the first airbag mechanism 400 and the second airbag mechanism 500 are connected to the air source device 200. The air source device 200 is positioned away from the headrest assembly 300, so when the user lies on the bed, the air source device 200 is away from the user's head, thereby reducing noise transmitted from the air source device 200 to the user's head.

[0023] For the bed frame 100 mentioned above, please refer to... Figure 2 The bed frame 100 includes a first mounting groove 110, a second mounting groove 120, and a receiving groove 130, which are sequentially arranged along the length direction X of the bed frame 100. A third mounting groove 140 is provided at the bottom of the receiving groove 130, and the third mounting groove 140 communicates with the receiving groove 130. The depth directions of the first mounting groove 110, second mounting groove 120, receiving groove 130, and third mounting groove 140 are all parallel to the height direction Y of the bed frame 100.

[0024] For the gas source device 200 mentioned above, please refer to... Figures 3-5 The air source device 200 is disposed within the third mounting slot 140. By sealing the opening of the third mounting slot 140, noise generated by the air source device 200 can be prevented from escaping the third mounting slot 140. The air source device 200 includes a housing 220 and an air pump 210. The housing 220 is provided with a noise-reducing mounting cavity, and the air pump 210 is disposed within the mounting cavity. The housing 220 encloses the air pump 210 within the mounting cavity via its inner wall, thereby preventing noise from escaping the mounting cavity from the air pump 210. Optionally, multiple air pumps 210 can be disposed within the housing 220.

[0025] The air pump 210 described above includes a pump body 211 and a noise reduction section 212. The pump body 211 has a first exhaust port 2111, and the noise reduction section 212 is disposed on the pump body 211. The noise reduction section 212 and the pump body 211 enclose and define a noise reduction cavity 2122, which has a second exhaust port 2121. The two opposite ends of the noise reduction cavity 2122 are respectively connected to the second exhaust port 2121 and the first exhaust port 2111. The cross-sectional area of ​​the noise reduction cavity 2122 is larger than that of the first exhaust port 2111, causing the gas velocity to drop sharply after exiting the first exhaust port 2111. The reduced gas velocity makes the gas flow smoother, reducing the likelihood of vortices. This significantly reduces the gas velocity and pulsation exiting the second exhaust port 2121, thus reducing the jet noise generated from the second exhaust port 2121. It should be noted that the cross-section of the first exhaust port 2111 refers to the cross-section of the first exhaust port 2111 along a direction perpendicular to the axis of the first exhaust port 2111, and the cross-section of the noise reduction cavity 2122 refers to the cross-section along a direction perpendicular to the axis of the first exhaust port 2111. It is understood that the embodiments of this utility model do not limit the number of the first exhaust port 2111 and the second exhaust port 2121; multiple first exhaust ports 2111 and multiple second exhaust ports 2121 can be provided as needed. Optionally, the noise reduction part 212 has a rough texture on the inner wall of the noise reduction cavity 2122, or the noise reduction part 212 has a sound-absorbing layer made of a sound-absorbing material on the inner wall of the noise reduction cavity 2122, thereby improving the sound absorption effect of the inner wall of the noise reduction part 212.

[0026] Optionally, the pump body is provided with an exhaust pipe extending into the noise reduction cavity 212. The first exhaust port 2111 is located at one end of the exhaust pipe in the noise reduction cavity 212, and the volume of the exhaust pipe is smaller than the volume of the noise reduction cavity 212. This causes the sound waves, which are small in volume, to suddenly enter the large in volume noise reduction cavity 212 after passing through the first exhaust port 2111. This causes the sound waves to expand and their wavefront to extend, resulting in a rapid decrease in sound energy. The sound waves reflect and collide back and forth within the large in volume noise reduction cavity 212, and some of the sound energy is converted into heat energy, thereby consuming noise.

[0027] Optionally, the orientation of the first exhaust port 2111 and the second exhaust port 2121 are staggered, forcing the airflow to change direction after exiting the first exhaust port 2111, thereby increasing the sound energy loss of noise. Furthermore, the orientation of the first exhaust port 2111 is inclined relative to the orientation of the second exhaust port 2121, causing the gas exiting the first exhaust port 2111 to rotate within the noise reduction cavity 2122, reducing the noise generated by the airflow directly impacting the inner wall of the noise reduction section 212, thus reducing noise. Additionally, the second exhaust port 2121 is oriented tangentially to the airflow trajectory, further reducing the noise generated by the airflow directly impacting the inner wall of the noise reduction section 212.

[0028] In some embodiments, the air source device 200 further includes a first buffer assembly 230. The first buffer assembly 230 includes a first buffer member 231, a first screw member 232, and a second screw member 233, with a first screw structure provided within the buffer member. The housing 220 is provided with a first through hole, and the air pump 210 further includes a first connecting portion 213, which is disposed on the pump body 211 and has a second through hole. The first screw member 232 passes through the first through hole and is screwed into the first screw structure, and the second screw member 233 passes through the second through hole and is screwed into the first screw structure. The first buffer member 231 is elastic, and when the air pump 210 vibrates, the first buffer member 231 can reduce the noise transmission rate, convert mechanical energy into heat energy, and reduce the risk of resonance. Optionally, there can be multiple first buffer assemblies 230, and the air pump 210 is fixedly installed on the housing 220 through multiple first buffer assemblies 230, thereby achieving stable support for the air pump 210.

[0029] For example, the first threaded connection structure can be an internal thread provided in the first buffer member 231, and both the first threaded member 232 and the second threaded member 233 are bolts. Alternatively, the first threaded connection structure can also be studs provided at both ends of the first buffer member 231, and both the first threaded member 232 and the second threaded member 233 are nuts.

[0030] Furthermore, one end of the first buffer 231 abuts against the first connecting portion 213 of the air pump 210, and the other end of the first buffer 231 abuts against the housing 220, so that the pump body 211 and the housing 220 are spaced apart, thereby greatly reducing noise and vibration transmitted through solids, thus achieving noise reduction. It should be noted that the above-mentioned arrangement of the first buffer 231 allows the portion of the pump body 211 facing the housing 220 to be spaced apart from the housing 220, and the other portions of the pump body 211 are also spaced apart from the housing 220, reducing the noise transmitted from the pump body 211 to the housing 220.

[0031] In some embodiments, the air source device 200 further includes a pressure relief valve 214. The pressure relief valve 214 is disposed in the noise reduction section 212. The pressure relief valve 214 is used to connect the noise reduction chamber 2122 with the outside air when the air pressure in the noise reduction chamber 2122 reaches a set threshold, thereby realizing pressure relief. This allows the noise reduction chamber 2122 to not only reduce noise but also limit the maximum air pressure, thereby stabilizing the pressure and reducing overpressure damage.

[0032] In some embodiments, the air source device 200 further includes a second buffer assembly 240. The second buffer assembly 240 includes a second buffer member 241, a third screwed member 242, and a fourth screwed member 243. The second buffer member 241 is elastic and is used to buffer vibrations generated by the air source device 200. A second screwed structure is provided within the second buffer member 241. The bed frame 100 has a third through hole at the bottom of the third mounting groove 140. The air source device 200 also includes a second connecting portion 250, which is disposed in the housing 220. The second connecting portion 250 has a fourth through hole. The third screwed member 242 passes through the third through hole and is screwed into the second screwed structure. The fourth screwed member 243 passes through the fourth through hole and is screwed into the second screwed structure. Optionally, there may be multiple second buffer assemblies 240. The air source device 200 is fixedly installed on the bed frame 100 through multiple second buffer assemblies 240, thereby achieving stable support for the air source device 200.

[0033] For example, the second threaded connection structure can be an internal thread provided in the second buffer member 241, and the third threaded member 242 and the fourth threaded member 243 are both bolts. Alternatively, the second threaded connection structure can also be studs provided at both ends of the second buffer member 241, the third threaded member 242 is provided with a threaded part 2421 and a bracket 2422, the threaded part 2421 is provided with an internal thread, the threaded part 2421 is threaded into the second threaded connection structure, and the bracket 2422 is located on the side of the bed frame 100 away from the receiving groove 130, thus fixing the air source device 200 to the bed frame 100, and the fourth threaded member 243 is a nut.

[0034] Furthermore, one end of the second buffer 241 abuts against the second connecting portion 250 of the housing 220, and the other end of the second buffer 241 abuts against the bottom wall of the bed frame 100 in the third mounting groove 140, so that the housing 220 and the bottom wall of the bed frame 100 in the third mounting groove 140 are spaced apart, thereby greatly reducing the noise transmitted through solids and thus achieving noise reduction.

[0035] For the headrest assembly 300 mentioned above, please refer to... Figure 1 The headrest assembly 300 is disposed in the first mounting slot 110.

[0036] In some embodiments, the headrest assembly 300 includes a third airbag mechanism connected to the air source device 200, which can adjust the firmness or height by inflating or deflating. After the third airbag mechanism is inflated, along the height direction of the bed frame 100, the top of the third airbag mechanism is flush with the opening of the first mounting groove 110, thus facilitating the third airbag mechanism to support the user's head.

[0037] For the first airbag mechanism 400 mentioned above, please refer to Figure 2The first airbag mechanism 400 is disposed in the second mounting groove 120, and the second airbag mechanism 500 is connected to the air source device 200, which can adjust the hardness or height by inflating or deflating. After the first airbag mechanism 400 is inflated, along the height direction of the bed frame 100, the top of the first airbag mechanism 400 away from the mounting plate 520 is flush with the groove opening of the second mounting groove 120, so that the first airbag mechanism 400 can support the user's torso.

[0038] For the second airbag mechanism 500 mentioned above, please refer to Figure 1 The second airbag mechanism 500 includes a cover plate 510 and an airbag assembly, the airbag assembly being connected to the air source device 200. The second airbag mechanism 500 is positioned above the air source device 200. The cover plate 510 covers the opening of the third mounting groove 140, and the airbag assembly is positioned above the cover plate 510, specifically on the side of the cover plate 510 facing away from the third mounting groove 140. The cover plate 510 effectively closes the opening of the third mounting groove 140, thereby reducing noise transmitted from the air source device 200 through the third mounting groove 140. Furthermore, the airbag assembly above the cover plate 510 further serves to block noise. Optionally, the cover plate 510 closes the opening of the third mounting groove 140, thus ensuring the noise-blocking effect of the cover plate 510.

[0039] The airbag assembly also includes a mounting plate 520 and an adjustable airbag 530. The thickness of the mounting plate 520 is less than the depth of the receiving groove 130, and the mounting plate 520 is disposed in the receiving groove 130. The adjustable airbag 530 is connected to the air source device 200. After the adjustable airbag 530 is inflated, along the height direction of the bed frame 100, the top of the adjustable airbag 530 facing away from the mounting plate 520 is flush with the opening of the receiving groove 130, thus facilitating the adjustment airbag 530 to support the user's feet. The cover plate 510 is fixedly disposed on the side of the mounting plate 520 facing the third mounting groove 140, and the adjustable airbag 530 is disposed above the mounting plate 520, that is, on the side of the mounting plate 520 facing away from the cover plate 510. At least a portion of the adjustable airbag 530 is located in the receiving groove 130. It is understandable that the adjustable airbag 530 does not need to be fixedly connected to the mounting plate 520. The adjustable airbag 530 is only supported by the mounting plate 520. During assembly, the adjustable airbag 530 can simply be placed on top of the mounting plate 520, which is simple and convenient. Alternatively, the mounting plate 520 can also be fixedly set on the adjustable airbag 530, and the installation of the adjustable airbag 530 is completed at the same time as the installation of the mounting plate 520.

[0040] It should be noted that on the side of the mounting plate 520 facing away from the third mounting groove 140, the mounting plate 520 and the bed frame 100 enclose and define a receiving space within the side wall of the receiving groove 130, and the adjustable airbag 530 is received within this receiving space. On the side of the mounting plate 520 facing the third mounting groove 140, the mounting plate 520 and the bed frame 100 enclose and define a noise reduction space within the side wall of the receiving groove 130, and the air source device 200 is located within this noise reduction space, thereby further blocking the propagation of noise. In this way, the mounting plate 520 can both support the adjustable airbag 530 and reduce noise.

[0041] Furthermore, along the height direction of the bed frame 100, the edge of the projection of the mounting plate 520 at least partially coincides with the edge of the projection of the receiving groove 130. The side wall of the bed frame 100 restricts the movement of the mounting plate 520, so that when the mounting plate 520 is set in the receiving groove 130, the cover plate 510 covers the third mounting groove 140. During assembly, it is not necessary to align the cover plate 510 with the opening of the third mounting groove 140, nor is it necessary to install the cover plate 510 separately on the bed frame 100, thus simplifying the assembly operation.

[0042] In some embodiments, the cover plate 510 is made of sound-absorbing material, and the bed frame 100 is provided with a noise reduction layer 150 on the inner wall of the third mounting groove 140. The noise reduction layer 150 is made of sound-absorbing material to absorb more noise.

[0043] In some embodiments, please combine Figure 6 The bed also includes a support structure 600, one end of which abuts against the bottom wall of the third mounting groove 140, and the other end of which abuts against the mounting plate 520. The mounting plate 520 is supported in such a way that it can be stably supported on the bed frame 100 by the support structure 600, and the mounting plate 520 can be assembled simply by placing it on top of the support structure 600, making assembly and disassembly convenient.

[0044] Furthermore, along the height direction of the bed frame 100, the top surface of the air source device 200 is flush with the opening of the third mounting groove 140, the cover plate 510 abuts against the air source device 200, the adjusting airbag 530 abuts against the mounting plate 520, and the mounting plate 520 abuts against the cover plate 510. This allows the air source device 200 to support the adjusting airbag 530, so that the adjusting airbag 530 is stably supported by the air source device 200 and the support structure 600.

[0045] Optionally, the third mounting slot 140 is formed on the top surface of the self-supporting structure 600 along the height direction Y of the bed frame 100. Alternatively, the third mounting slot 140 is defined by the support structure 600 and the bed frame 100 enclosing the side wall of the receiving slot 130.

[0046] In some embodiments, the bed further includes a lifting airbag 700, a portion of which is disposed above the second mounting slot 120, and another portion of which is disposed above the receiving slot 130. The lifting airbag 700 is used to adjust the height of the user's knees. A fixing plate 640 is also provided on the top of the support structure 600, and a receiving slot 641 is provided on the top surface of the fixing plate 640. An inlet 642 is provided at one end of the fixing plate 640 near the third mounting slot 140, and the inlet 642 communicates with the third mounting slot 140. An outlet 643 is provided at the end of the fixing plate 640 away from the third mounting slot 140, and the inlet 642 and outlet 643 are respectively connected to the two ends of the receiving slot 641. The bed also includes an airway assembly 800, which includes a main body, a first connecting portion 213, and a second connecting portion 250, which are respectively connected to the two ends of the main body. The main body of the air circuit assembly 800 is housed in the receiving groove 641 of the fixing plate 640, with the main body lower than the opening of the receiving groove 641. This design ensures a compact structure and a flat top surface for the support structure 600 when supporting the air source device 200, allowing for stable support of the air source device 200. The first connecting portion 213 of the air circuit assembly 800 extends out of the inlet 642 and connects to the air source device 200, while the second connecting portion 250 extends out of the outlet 643 and connects to the lifting airbag 700.

[0047] Furthermore, the support structure 600 also includes a sealing plate 650, which covers the opening of the receiving groove 641 to close at least a portion of the receiving groove 641. The sealing plate 650 prevents the air passage assembly 800 from extending out of the receiving groove 641 along the height direction Y of the bed frame 100, thereby preventing the adjusting airbag 530 from compressing the air passage assembly 800. It is understood that the sealing plate 650 has a flat structure and can be made of adhesive tape. Optionally, there can be multiple sealing plates 650, which are arranged sequentially at intervals along the length direction of the air passage assembly 800, so that any shape of the sealing plate 650 can be closed by multiple spaced-apart sealing plates 650.

[0048] Optionally, two lifting airbags 700 are sequentially arranged along the width direction Z of the bed frame 100. Two air passage assemblies 800 and two receiving slots 641 are also provided. The main body of one air passage assembly 800 is housed in one receiving slot 641, and the second connecting part 250 of one air passage assembly 800 is connected to one lifting airbag 700.

[0049] In some embodiments, the support structure 600 includes a first sub-support structure 610, a second sub-support structure 620, and a third sub-support structure 630. The first sub-support structure 610, the second sub-support structure 620, and the third sub-support structure 630 are arranged sequentially along the width direction Z of the bed frame 100. The second sub-support structure 620 is disposed on the side of the receiving groove 130 near the second mounting groove 120. The first sub-support structure 610, the second sub-support structure 620, the third sub-support structure 630, and the side wall of the receiving groove 130 away from the second mounting groove 120 enclose and define the third mounting groove 140, such that the air source device 200 is located at the position furthest from the headrest assembly 300 within the receiving groove 130. There are two fixing plates 640. One fixing plate 640 is provided with a receiving groove 641. One fixing plate 640 is disposed on the top surface of the first sub-support structure 610, and the other fixing plate 640 is disposed on the top surface of the third sub-support structure 630. Along the width direction Z of the bed frame 100, both ends of the second sub-support structure 620 are provided with through holes 621, one through hole 621 communicating with the third mounting groove 140 and the inlet 642 on a fixing plate 640 respectively. The first connecting part 213 on the fixing plate 640 passes through the through hole 621 and is connected to the air source device 200.
