Description

Technical Field

[0001] This invention relates to the field of mattress technology, specifically a pneumatic spring isobaric self-adjusting system based on spinal parameter recognition. Background Technology

[0002] A mattress is an item placed between the human body and the bed to ensure that consumers get healthy and comfortable sleep. There are many types of mattress materials, and mattresses made of different materials can bring different sleep effects. At the same time, long-term use of a mattress can also affect the user's spinal health.

[0003] Due to high-intensity study or work, or problematic sleep habits, most adults experience lumbar muscle strain and spinal issues. When lying flat or on their side in bed, the lack of lumbar support prevents the spine from naturally extending, leading to lower back pain and discomfort. In response, a range of mattresses designed to improve spinal health have emerged on the market.

[0004] However, existing mattresses designed to improve spinal health, such as common spinal correction mattresses, are all made up of individual sections with a fixed structure and a fixed distribution of internal springs. In actual use, the effects vary among different users, making it difficult to improve spinal health. In fact, long-term use may even have adverse effects on spinal health. Summary of the Invention

[0005] The purpose of this invention is to provide a pneumatic spring isobaric self-adjusting system based on spinal parameter identification to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pneumatic spring isobaric self-regulating system based on spinal parameter identification includes:

[0008] The sensing unit is used to monitor the state changes of the pneumatic spring mounted on the base in real time.

[0009] The central processing unit establishes communication with the sensing unit. The central processing unit is used to receive the sensing signal sent by the sensing unit when the sensing unit detects a change in the state of the pneumatic spring and the state of the pneumatic spring after the change tends to stabilize.

[0010] The timing unit interacts with the central processing unit. After the central processing unit receives the sensing signal, the timing unit is triggered to time the duration of the sensing signal. After the time value reaches a preset value, the timing module sends a feedback signal to the central processing unit.

[0011] The execution unit establishes communication with the central processing unit. When the central processing unit receives a feedback signal sent by the timing unit, it will communicate with the execution unit to trigger the execution unit.

[0012] As a further aspect of the present invention: the execution unit includes:

[0013] A capture module, which is triggered by the central processing unit after receiving the feedback signal, is used to record the current state of the pneumatic spring;

[0014] The receiving module establishes communication with the capturing module to receive information recorded by the capturing module regarding the state of the pneumatic spring.

[0015] The conversion module establishes communication with the receiving module to receive information recorded by the capture module regarding the state of the pneumatic spring, and performs digital-to-analog conversion processing on the information.

[0016] The control panel is used for users to input human body features, and the control panel communicates with an extraction module. The extraction module is used to extract the reserved spinal parameter information in the memory according to the human body features, and send the extracted spinal parameter information to the comparison module that communicates with it, and compare it with the information after digital-to-analog conversion by the conversion module.

[0017] The isobaric adjustment module communicates with the comparison module, and is triggered after the comparison module completes the comparison process. It is used to adjust the state of the pneumatic spring so that the force on the human body is balanced.

[0018] The drawing module communicates with the comparison module to receive the information comparison results sent by the comparison module, and draws images based on the information comparison results. The display module then displays the spinal health analysis and recommendations.

[0019] After the drawing module completes the drawing of the image based on the information comparison results, it sends the drawn image to the database for storage. At the same time, the database communicates with the statistics module, which extracts the image information from the database to generate a curve of changes in spinal health through the display module.

[0020] As a further aspect of the present invention: the human body characteristics include the user's height and weight parameters.

[0021] As a further embodiment of the present invention: the isobaric regulation module includes:

[0022] An air inlet is located at the bottom of the cylinder and is connected to an air supply mechanism mounted on the base. The air supply mechanism is triggered during the descent of the pneumatic spring piston rod and causes the air inlet to open, so as to pump filling gas into the cylinder.

[0023] A collar is slidably fitted on the outer wall of the pneumatic spring cylinder and connected to multiple sets of elastic telescopic mechanisms installed on the outer periphery of the cylinder. The collar is used to block the air outlet opened on the cylinder.

[0024] A vertical plate is fixedly installed on the piston rod, and a sliding engagement mechanism is provided at the end of the vertical plate away from the piston rod. The sliding engagement mechanism cooperates with the driven mechanism installed on the collar. The driven mechanism is triggered when the vertical plate moves upward with the piston rod, and causes multiple sets of elastic telescopic mechanisms to store elastic potential energy, so that the collar performs a reciprocating sliding action on the cylinder body, and conducts a passage to the air outlet.

[0025] As a further embodiment of the present invention: the air supply mechanism includes a gear transmission assembly installed on the base and connected to the piston rod, and an air guide assembly installed between the base and the cylinder. The air guide assembly includes a rotating tube rotatably installed on the base, an annular body fixedly installed at one end of the rotating tube away from the base and in sealed sliding contact with the bottom of the cylinder, and an air storage tank installed on the base.

[0026] The gas storage tank is connected to a sleeve via a valve body. The sleeve is rotatably and sealed to the rotating pipe. The rotating pipe has multiple venting grooves equidistantly spaced along its circumference. The ring body is hollow inside and communicates with the rotating pipe. An arc-shaped through groove is provided on the upper part of the ring body. The width of the arc-shaped through groove along the radial direction of the ring body gradually increases or decreases along the circumference of the ring body.

[0027] As a further embodiment of the present invention: the gear transmission assembly includes a rack plate fixedly mounted on the piston rod and a gear and a transmission shaft rotatably mounted on the base. The transmission shaft is connected to the rotating tube by a transmission belt, and the end of the transmission shaft away from the base is connected to the rotating shaft of the gear by a bevel gear set.

[0028] As a further embodiment of the present invention: the driven mechanism includes a first hollow plate fixedly installed on the outer wall of the collar, a first telescopic plate slidably fitted with the first hollow plate, and a pulley rotatably installed on the first telescopic plate at the end away from the collar.

[0029] The first telescopic plate has a protrusion fixed at one end away from the pulley. A crossbar is fixed to the side of the first hollow plate by a protrusion block. The crossbar passes through the protrusion and is slidably connected to it. A second columnar spring is also sleeved on the outer periphery of the crossbar. The two ends of the second columnar spring are respectively connected to the protrusion block and the protrusion. A strip-shaped opening is provided on the first hollow plate for the movement of the protrusion.

[0030] As a further embodiment of the present invention: the sliding engagement mechanism includes a second hollow plate fixed to the end of the vertical plate away from the piston rod and a second telescopic plate slidably disposed in the second hollow plate. The second telescopic plate is arranged in an L-shape, and the end away from the second hollow plate is provided with a barb. It is provided with an inclined surface, a flat surface and a vertical surface.

[0031] Two columns are fixed at one end of the second telescopic plate inside the second hollow plate. A strip-shaped through groove for the columns to move is opened on each side of the second hollow plate. Two limiting rods are fixed on the outer wall of the cylinder, respectively located on both sides of the second hollow plate. Limiting grooves are opened on the limiting rods. The columns pass through the limiting grooves and are slidably connected to the limiting rods. The limiting grooves include inclined sections and vertical sections.

[0032] As a further embodiment of the present invention: the elastic telescopic mechanism includes a guide cylinder and a telescopic rod fixedly installed on the outer wall of the cylinder body, the telescopic rod being slidably fitted with the guide cylinder, and one end of the telescopic rod being fixed to the collar;

[0033] The guide cylinder is also equipped with a first cylindrical spring. One end of the first cylindrical spring is connected to the cylinder wall of the guide cylinder, and the other end is connected to the end of the telescopic rod away from the collar.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention has a novel design. After the state of the pneumatic spring tends to stabilize, the central controller sends a sensing signal to the timing unit, which is then triggered to start timing. After the timing reaches the preset value, the user's lying posture has been adjusted and remains in a relatively stable state. Then, the timing unit sends a feedback signal to the central controller, which then sends a control signal to the execution unit to make the execution unit work, perform some analysis of human spinal parameters, and provide a series of feasible health suggestions based on previous indicators. Therefore, the system has high completeness and, when applied to mattress products, can greatly improve the user experience and improve the user's spinal health. Attached Figure Description

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0047] Please see Figure 1-2 A pneumatic spring isobaric self-regulating system based on spinal parameter identification, comprising:

[0048] The sensing unit is used to monitor the state changes of the pneumatic spring installed on the base 1 in real time.

[0049] The central processing unit establishes communication with the sensing unit. The central processing unit is used to receive the sensing signal sent by the sensing unit when the sensing unit detects a change in the state of the pneumatic spring and the state of the pneumatic spring after the change tends to stabilize.

[0050] The timing unit interacts with the central processing unit. After the central processing unit receives the sensing signal, the timing unit is triggered to time the duration of the sensing signal. After the time value reaches a preset value, the timing module sends a feedback signal to the central processing unit.

[0051] The execution unit establishes communication with the central processing unit. When the central processing unit receives a feedback signal sent by the timing unit, it will communicate with the execution unit to trigger the execution unit.

[0052] It should be noted that the preset value is set by the user in advance, and its value is adjusted by the feedback signal sent by the timing unit to the central controller. That is, when the pneumatic spring is applied to the actual product (such as a mattress, etc.), the state of the human body after lying down tends to be stable. After the state of the pneumatic spring tends to be stable, the central controller will send a sensing signal to the timing unit, which will then be triggered to start timing. After the timing reaches the preset value, it indicates that the user's lying posture has been adjusted and remains in a relatively stable state. Then, the timing unit sends a feedback signal to the central controller, which in turn sends a control signal to the execution unit to make the execution unit work, perform some analysis of human spinal parameters, and provide a series of feasible health suggestions based on previous indicators.

[0053] The execution unit includes:

[0054] A capture module, which is triggered by the central processing unit after receiving the feedback signal, is used to record the current state of the pneumatic spring;

[0055] The receiving module establishes communication with the capturing module to receive information recorded by the capturing module regarding the state of the pneumatic spring.

[0056] The conversion module establishes communication with the receiving module to receive information recorded by the capture module regarding the state of the pneumatic spring, and performs digital-to-analog conversion processing on the information.

[0057] The control panel is used for users to input human body features, and the control panel communicates with an extraction module. The extraction module is used to extract the reserved spinal parameter information in the memory according to the human body features, and send the extracted spinal parameter information to the comparison module that communicates with it, and compare it with the information after digital-to-analog conversion by the conversion module.

[0058] The isobaric adjustment module communicates with the comparison module, and is triggered after the comparison module completes the comparison process. It is used to adjust the state of the pneumatic spring so that the force on the human body is balanced.

[0059] The drawing module communicates with the comparison module to receive the information comparison results sent by the comparison module, and draws images based on the information comparison results. The display module then displays the spinal health analysis and recommendations.

[0060] After the drawing module completes the drawing of the image based on the information comparison results, it sends the drawn image to the database for storage. At the same time, the database communicates with the statistics module, which extracts the image information from the database to generate a curve of changes in spinal health through the display module.

[0061] The human characteristics include the user's height and weight parameters.

[0062] Specifically, before using the product, users can input their height and weight information into the system through the control panel and send it to the extraction module. The extraction module will then extract the healthy and qualified spinal information corresponding to the user's height and weight from the memory based on the information input by the user.

[0063] Preferably, in actual implementation, the product can be equipped with height and weight measurement functions. The user's height and weight measurement results will be directly sent to the extraction module, so that the extraction module can extract the corresponding healthy and qualified spinal information from the memory, which will facilitate subsequent comparison and display of spinal health analysis and suggestions.

[0064] Please see Figure 3-9 The isobaric regulation module includes:

[0065] An air inlet 201 is located at the bottom of the cylinder 2 and is connected to an air supply mechanism mounted on the base 1. The air supply mechanism is triggered during the descent of the pneumatic spring piston rod 3 and causes the air inlet 201 to open, so as to pump filling gas into the cylinder 2.

[0066] The collar 4 is slidably fitted on the outer wall of the pneumatic spring cylinder 2 and connected to multiple sets of elastic telescopic mechanisms installed on the outer periphery of the cylinder 2. The collar 4 is used to block the air outlet 202 opened on the cylinder 2.

[0067] A vertical plate 12 is fixedly installed on the piston rod 3, and a sliding engagement mechanism is provided at the end of the vertical plate 12 away from the piston rod 3. The sliding engagement mechanism cooperates with the driven mechanism installed on the collar 4. The driven mechanism is triggered when the vertical plate 12 moves upward with the piston rod 3, and causes multiple sets of elastic telescopic mechanisms to store elastic potential energy, so that the collar 4 performs a reciprocating sliding action on the cylinder 2, and conducts a connection to the air outlet 202.

[0068] It should be further noted that the filling gas is an inert gas (usually nitrogen).

[0069] The air supply mechanism includes a gear transmission assembly installed on the base 1 and connected to the piston rod 3, and an air guide assembly installed between the base 1 and the cylinder 2. The air guide assembly includes a rotating pipe 23 rotatably installed on the base 1, an annular body 22 fixedly installed at one end of the rotating pipe 23 away from the base 1 and in sealed sliding contact with the bottom of the cylinder 2, and an air storage tank 26 installed on the base 1.

[0070] The gas storage tank 26 is connected to a sleeve 24 via a valve body 25. The sleeve 24 is rotatably connected to the rotating pipe 23 in a sealed manner. The rotating pipe 23 has multiple venting grooves 2301 equidistantly spaced along its circumference. The ring body 22 is hollow inside and communicates with the rotating pipe 23. An arc-shaped through groove 2201 is provided on the upper part of the ring body 22. The width of the arc-shaped through groove 2201 along the radial direction of the ring body 22 gradually increases or decreases along the circumference of the ring body 22.

[0071] The gear transmission assembly includes a rack plate 17 fixedly mounted on the piston rod 3, a gear 18 rotatably mounted on the base 1, and a transmission shaft 20. The transmission shaft 20 is connected to the rotating tube 23 by a transmission belt 21, and the end of the transmission shaft 20 away from the base 1 is connected to the rotating shaft of the gear 18 by a bevel gear set 19.

[0072] In detail, the bevel gear set 19 includes a first bevel gear fixedly mounted coaxially with the gear 18 and a second bevel gear fixedly mounted on the end of the transmission shaft 20 away from the base 1, and the second bevel gear meshes with the first bevel gear.

[0073] When the pneumatic spring receives pressure and causes the piston rod 3 to retract downwards, the piston rod 3 will drive the rack plate 17 to move downwards. The rack plate 17 then drives the gear 18 to rotate. The rotation shaft of the gear 18 drives the transmission shaft 20 to rotate via the bevel gear set 19. The transmission shaft 20 then drives the rotating tube 23 and the ring body 22 to rotate via the transmission belt 21. When the ring body 22 rotates, the air inlet 201 will overlap with the arc-shaped through groove 2201. As the ring body 22 rotates, the width of the overlap between the arc-shaped through groove 2201 and the air inlet 201 gradually decreases. Then, after the piston rod 3 stabilizes, the valve body 25 opens for a specific time. The gas in the gas tank 26 can enter the rotating tube 23 through the valve body 25, sleeve 24 and venting groove 2301, and then enter the cylinder 2 through the ring 22, arc-shaped groove 2201 and air inlet 201. As a result, the greater the downward movement of the piston rod 3, the greater the rotation angle between the gear 18 and the ring 22, and the smaller the overlap area between the arc-shaped groove 2201 and the air inlet 201. Consequently, the amount of gas pumped into the cylinder 2 by the gas tank 26 is reduced during the specific time the valve body 25 is open. Finally, in the entire system, the force of each pneumatic spring supporting various parts of the human body is equal, thereby increasing the comfort of the human body.

[0074] The driven mechanism includes a first hollow plate 9 fixedly installed on the outer wall of the collar 4, a first telescopic plate 10 slidably fitted with the first hollow plate 9, and a pulley 11 rotatably installed on the end of the first telescopic plate 10 away from the collar 4. A protrusion 1001 is fixed to the end of the first telescopic plate 10 away from the pulley 11. A crossbar 902 is fixed to the side of the first hollow plate 9 via a protrusion 901. The crossbar 902 passes through the protrusion 1001 and is slidably connected to it. A second cylindrical spring 8 is also sleeved on the outer periphery of the crossbar 902. The two ends of the second cylindrical spring 8 are respectively connected to the protrusion 901 and the protrusion 1001. A strip-shaped opening is provided on the first hollow plate 9 for the movement of the protrusion 1001.

[0075] The sliding engagement mechanism includes a second hollow plate 13 fixed to one end of the vertical plate 12 away from the piston rod 3 and a second telescopic plate 14 slidably disposed in the second hollow plate 13. The second telescopic plate 14 is arranged in an L-shape, and the end away from the second hollow plate 13 is provided with a barb. It is provided with an inclined surface 1401, a flat surface 1402 and a vertical surface 1403.

[0076] Two columns 15 are fixed at one end of the second telescopic plate 14 located inside the second hollow plate 13. A strip-shaped through groove 1301 for the column 15 to move is provided on each side of the second hollow plate 13. Two limiting rods 16 are fixed on the outer wall of the cylinder 2, respectively located on both sides of the second hollow plate 13. A limiting groove is provided on the limiting rod 16. The column 15 passes through the limiting groove and is slidably connected to the limiting rod 16. The limiting groove includes an inclined section 1601 and a vertical section 1602.

[0077] Initially, the second telescopic plate 14 and the pulley 11 are misaligned. When the vertical plate 12 moves down with the piston rod 3, the column 15 will first slide with the limiting rod 16. As the column 15 slides from the inclined section 1601 to the vertical section 1602, the second telescopic plate 14 gradually slides towards the inside of the second hollow plate 13. When the column 15 slides into the vertical section 1602, the inclined surface 1401 is aligned with the pulley 11. As the piston rod 3 continues to move down, the pulley 11 will be squeezed by the inclined surface 1401, causing the first telescopic plate 10 to gradually slide towards the first hollow plate 9. The second columnar spring 8 is compressed. After the pulley 11 separates from the inclined surface 1401, the second columnar spring 8 rebounds, and the pulley 11 moves to the upper part of the flat surface 1402 and abuts against the vertical surface 1403.

[0078] After the pressure on the pneumatic spring disappears, during the upward reset process of the piston rod 3, firstly, the column 15 slides upward in the vertical section 1602. After the pulley 11 abuts against the flat surface 1402, the second telescopic plate 14 will drive the collar 4 to slide upward a certain distance on the cylinder 2 through the pulley 11, so that the air outlet 202 is open. Thus, some of the gas in the cylinder 2 is discharged, realizing the restoration of the internal state of the cylinder 2. During this process, the multiple sets of elastic telescopic mechanisms store a certain amount of elastic potential energy. Finally, in the latter part of the stroke of the piston rod 3, the column 15 will slide from the vertical section 1602 into the inclined section 1601, so that the second telescopic plate 14 gradually slides towards the outside of the second hollow plate 13. Then, the second telescopic plate 14 will be misaligned with the pulley 11 again. Correspondingly, the multiple sets of elastic telescopic mechanisms release elastic potential energy, so that the collar 4 slides down and resets on the cylinder 2, and blocks the air outlet 202 again.

[0079] The elastic telescopic mechanism includes a guide cylinder 6 and a telescopic rod 7 fixedly installed on the outer wall of the cylinder 2. The telescopic rod 7 is slidably fitted with the guide cylinder 6, and one end of the telescopic rod 7 is fixed to the collar 4. A first cylindrical spring 5 is also provided inside the guide cylinder 6. One end of the first cylindrical spring 5 is connected to the cylinder wall of the guide cylinder 6, and the other end is connected to the end of the telescopic rod 7 away from the collar 4.

[0080] When the second telescopic plate 14 slides upward through the pulley 11, releasing the blockage of the air outlet 202, the telescopic rod 7 slides towards the inside of the guide cylinder 6, compressing the first cylindrical spring 5. Thus, when the second telescopic plate 14 rises to a later stage and is misaligned with the pulley 11, the first cylindrical spring 5 rebounds, causing the telescopic rod 7 to slide towards the outside of the guide cylinder 6. Because the first cylindrical spring 5 rebounds quickly, it can quickly block the air outlet 202.

[0081] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0082] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
