Description

An adaptive device for a pneumatic mattress and its usage method Technical Field

[0001] This invention belongs to the field of home air mattress technology, specifically relating to an adaptive device for a pneumatic mattress and its usage method. Background Technology

[0002] An air mattress is a type of mattress made of PVC or other synthetic materials that adjusts its firmness and volume by inflating and deflating air. This type of mattress needs to be inflated before use and can be deflated and folded away when not in use, taking up little space and making it easy to store and carry. Air mattresses typically have good flexibility, providing a comfortable sleeping experience, and unlike some types of mattresses, they do not sag or lose elasticity over time. Furthermore, because their materials are often waterproof, air mattresses are also moisture-proof and can be used directly on the floor without a bed frame.

[0003] Air mattresses have several advantages over spring mattresses. First, PVC material is highly flexible and elastic, making it ideal for inflatable products. It can typically withstand several tons of weight, and most air mattresses are sturdy and durable. Second, air mattresses fold up to the size of a pillow, making them very easy to carry and store. When not in use, they can be folded and stored in a cabinet; when needed, they can be simply inflated and used. Furthermore, unlike spring mattresses, air mattresses don't harbor bacteria or deform.

[0004] Existing pneumatic mattresses offer good body contouring, but most are one-piece designs with a fixed shape. When a user lies on a pneumatic mattress, their body is in a horizontal position, which is not ergonomically designed. The back or side of the body is not completely horizontal. Prolonged use of a flat mattress can cause the body to be in an unnatural position and posture, affecting sleep. When lying flat on a pneumatic mattress, the head is in a relatively low position, which can affect blood flow and oxygen supply to the brain, leading to insufficient blood supply to the head. A low head sleeping posture can cause spinal curvature or twisting, requiring the back muscles to exert extra force to maintain balance and stability. Over time, this can increase the burden on local muscles, causing local fatigue and reducing the restful sleep effect. The neck is also forced into a twisted or uncomfortable position, which can cause pressure and discomfort on the cervical joints, increasing the likelihood of stiff neck. Furthermore, some angled pneumatic mattresses are difficult to adjust to user preferences or adapt to their own shape. The inflatable nature of pneumatic mattresses also means that they are difficult to adjust, limiting the mattress's effectiveness and significantly reducing the user experience. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides an adaptive device for a pneumatic mattress and its usage method, aiming to solve the technical problem that pneumatic mattresses cannot adaptively adjust according to user preferences in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adaptive device for a pneumatic mattress, which satisfies the different usage preferences of different users. The adaptive device includes a pneumatic center pad, a pneumatic headrest pad at one end of the pneumatic center pad, a pneumatic footrest pad at the other end of the pneumatic center pad, a rear bottom plate at the bottom of the pneumatic center pad, and a front bottom plate on one side of the rear bottom plate. The pneumatic center pad, the pneumatic headrest pad, and the pneumatic footrest pad are all composed of independent airbags.

[0007] The pneumatic head pad is fixed with an upper base pad at the bottom, the pneumatic tail pad is fixed with an upper base pad at the bottom, the upper base pad is fixed with an upper conductive coating at the bottom, the upper conductive coating is provided with an isolation point at the bottom, the isolation point is fixed with a lower conductive coating at the bottom, the lower conductive coating is fixed with an aerogel felt layer at the bottom, and the aerogel felt layer is fixed with a bending plate at the bottom.

[0008] A fixing plate is provided below the bending plate. A shaft steel ball is nested between the bottom of the bending plate and the top of the fixing plate. A circular groove is opened on the surface of the bending plate. A shim is fixed to the top of the circular groove. An adjusting bolt is fixed to the top of the shim. A threaded post is threaded to the inner wall of the adjusting bolt. A motor is fixed to the bottom of the threaded post. The motor is fixed to the inner wall of the fixing plate. A rear base plate is fixed to the bottom of the fixing plate.

[0009] Furthermore, locking gears are fixed on both sides of the bending plate, and corner-cutting blocks are meshed on the surface of the locking gears. A sliding column is fixed at the bottom of the corner-cutting blocks, and a return spring is fixed at the bottom of the sliding column. An electromagnet is fixed at one end of the return spring. The bottom of the electromagnet is fixed to the inner wall of the fixed plate, and a ring is fixed at the top of the electromagnet. The inner wall of the ring is slidably connected to the circumference of the sliding column.

[0010] Furthermore, a round-headed groove is formed on the surface of the bending plate, a disc spring is fixed to the top of the round-headed groove, a fixing nail is fixed to the top of the disc spring, and the bottom of the fixing nail is fixed to the top of the fixing plate.

[0011] Furthermore, a shaft column is fixed to one side of the rear base plate, and shaft plates are rotatably connected to both sides of the shaft column, with a front base plate fixed to one end of the shaft plate.

[0012] Furthermore, the bottom of the rear base plate is provided with anti-slip grooves in a linear array, and the bottom of the front base plate is provided with anti-slip grooves in a linear array.

[0013] Furthermore, friction-enhancing rubber pads are fixed on both sides of the bottom of the rear base plate, and friction-enhancing rubber pads are fixed on both sides of the bottom of the front base plate.

[0014] Furthermore, both sides of the rear bottom plate are provided with transport grooves, and both sides of the front bottom plate are provided with transport grooves.

[0015] Furthermore, the length of the round head groove is greater than the diameter of the fixing pin, and the diameter of the round through groove is greater than the diameter of the threaded post.

[0016] Furthermore, the surface of the pneumatic head pad is covered with a heating layer, the surface of the pneumatic middle pad is covered with a heating layer, and the surface of the pneumatic tail pad is covered with a heating layer.

[0017] Furthermore, the steps for using the aforementioned pneumatic mattress adaptive device are as follows:

[0018] Step 1: Before use, users can customize and adjust the mattress settings according to their preferences via the user app, including but not limited to settings for time, angle, movement, and temperature.

[0019] Step 2: When the user lies on the mattress, the independent airbags are compressed, causing them to expand and the upper conductive coating of the upper base pad to move downwards across the gap of the isolation point and contact the lower conductive coating, causing a change in the current on the surface of the lower conductive coating. By analyzing the change in current, the mattress can grasp the user's current posture.

[0020] Step 3: Once the mattress has grasped the user's current posture, it can make different adaptive adjustments based on the user's pre-set settings. For example, if the user sets that the pneumatic headboard should tilt upwards by 30 degrees when in the "sitting up" position, the mattress motor will start, causing the threaded column to screw into the adjusting bolt downwards. The pressure of the pads will cause the bending plate to rotate counterclockwise by the steel ball bearing, thus tilting the pneumatic headboard to meet the user's requirements.

[0021] Step 4: When the pneumatic headstock tilts upward, the locking gear also rotates with the bending plate. When the locking gear rotates, due to the chamfering structure of the chamfering block, the chamfering block is pressed downward into the ring. The return spring continuously pushes the chamfering block out of the ring, so that the locking gear cannot reverse its direction on its own, thus locking the rotation angle of the equipment and providing users with safety and stability.

[0022] Step 5: When the user leans against the pneumatic headboard, pressure is applied to the pneumatic headboard. The bending plate tends to reverse under pressure, and the disc spring releases the elastic potential energy accumulated when the bending plate rotates in "Step 3", applying pressure to the bending plate and providing cushioning at the same time.

[0023] Step Six: When the user leaves, the mattress automatically adjusts, the electromagnet retracts the slide into the ring, and the motor rotates in the opposite direction to reset the pneumatic headrest.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. In existing technologies, pneumatic mattresses can provide users with a good fit. However, most pneumatic mattresses are one-piece designs with a fixed shape. When a user lies on a pneumatic mattress, their body is in a horizontal position, which does not conform to ergonomic design. The back or side of the body is not completely horizontal. Prolonged use of a flat mattress will put the body in an unnatural position and posture, affecting the user's sleep. When lying flat on a pneumatic mattress, the head is in a relatively low position, which will affect blood flow and oxygen supply to the brain, causing insufficient blood supply to the head. A low head sleeping posture can lead to spinal curvature or twisting, requiring the back muscles to exert extra strength to maintain the body's balance and stability. Over time, this can easily increase the burden on local muscles, causing local fatigue and reducing the restful effect of sleep. The neck will also be affected. Forcing oneself into a twisted or uncomfortable position can easily cause pressure and discomfort on the cervical spine joints, increasing the likelihood of stiff neck. Furthermore, some angled pneumatic mattresses are difficult to adjust to user preferences or self-adjust. The inflatable nature of pneumatic mattresses also means they are difficult to adjust, limiting their effectiveness and significantly reducing the user experience. Therefore, in this device, the pneumatic mattress first uses independent airbags to reduce the risk of rupture when pierced by sharp objects. Second, the combination of upper and lower conductive coatings collects the user's posture, further improving the user experience. Finally, the combination of a bending plate and a threaded column assembly adjusts the angles of the pneumatic headboard and footboard at user-defined times or postures, increasing the intelligent self-adjustment of the pneumatic mattress and enhancing the user experience.

[0026] 2. In existing technologies, some users adjust the angle of the pneumatic bed after lying down. At this time, due to the pressure of the human body on the pneumatic mattress, if the pressure exceeds the stress limit of the components, the bending plate will rotate backward, causing damage to the threads of the adjusting bolt and threaded column, resulting in "slippage" and rendering the equipment unusable. In this invention, the combination of a locking gear and a corner block is used. When the bending plate rotates normally, the corner block, due to its corner-cutting characteristics, enables the locking gear to move normally. However, when subjected to pressure, the rotation is restricted by the corner block, and the locking gear cannot reverse direction on its own, thus locking the device's turning angle, providing users with safety and stability, increasing the equipment's service life, and improving the user experience.

[0027] 3. When the pneumatic mattress is at an angle, if the user forcefully impacts it, the mattress will receive excessive hard impact in a short period of time. This can not only cause injury to the user due to the reaction force, resulting in a reduced user experience, but also damage some components and reduce the lifespan of the equipment. In this invention, a disc spring is used to mitigate the force caused by the impact. The disc spring absorbs and accumulates the impact, and then slowly releases it to reset the pneumatic mattress, limiting its vibration range and avoiding excessive positional changes caused by vibration that could damage the equipment. It also prevents user injury and improves the user experience. The rounded groove prevents the bending plate from colliding with the fixing nail, increasing the lifespan of the equipment and ensuring safe and stable use.

[0028] 4. The combination of the shaft column and shaft plate allows users to fold it up or carry it, improving the user experience. The anti-slip groove and friction-enhancing rubber pad increase the friction with the bed board or floor while providing a gap between the mattress and the contact surface of the bed board or floor, increasing air circulation and preventing the mattress from getting moldy. The carrying groove makes it easy for staff or users to move the mattress, and the heating layer makes it easy for staff to adjust the mattress temperature. The above structure is based on the ergonomic design concept, starting from a human-centered perspective, covering a wide range of usage scenarios, making it easy for users and pre-sales staff to use, and greatly enhancing the user experience.

In the system, to ensure the angle adjustment effect and prevent component damage, the length of the circular groove is greater than the diameter of the fixing pin, and the diameter of the circular groove is greater than the diameter of the threaded post.

[0051] In this embodiment, in order to provide users with safety and stability and increase the service life of the equipment, an angle locking system is provided. This system includes: locking gears are fixed on both sides of the bending plate, corner cutting blocks are meshed on the surface of the locking gears, a sliding column is fixed at the bottom of the corner cutting blocks, a return spring is fixed at the bottom of the sliding column, an electromagnet is fixed at one end of the return spring, the bottom of the electromagnet is fixed to the inner wall of the fixed plate, and a ring is fixed at the top of the electromagnet.

[0054] Example 2:

[0055] The usage method of the pneumatic mattress self-adjusting device is as follows:

[0056] Step 1: Before use, users can customize and adjust the mattress settings according to their preferences via the user app, including but not limited to settings for time, angle, movement, and temperature.

[0057] Step 2: When the user lies on the mattress, the independent airbag 103 is compressed, causing it to expand and the upper conductive coating 201 of the upper base pad 2 to move downwards across the gap of the isolation point 202 and contact the lower conductive coating 203, causing a change in the current on the surface of the lower conductive coating 203. By analyzing the change in current, the mattress can grasp the user's current posture.

[0058] Step 3: After the mattress grasps the user's current posture, it can make different adaptive adjustments according to the user's pre-set settings. For example, when the user sets that the pneumatic headboard 101 should tilt upwards by 30 degrees when in the "sitting up" position, the mattress motor 304 will start, causing the threaded column 306 to be screwed into the adjusting bolt 307 downwards. The pad 308 will press down, causing the bending plate 205 to rotate counterclockwise by the shaft steel ball 3, thus tilting the pneumatic headboard 101 to meet the user's requirements.

[0059] Step 4: When the pneumatic headstock 101 tilts upward, the locking gear 4 also rotates along with the bending plate 205. When the locking gear 4 rotates, due to the chamfering structure of the chamfering block 401, the chamfering block 401 is pressed downward into the ring 403. The return spring 404 continuously pushes the chamfering block 401 out of the ring 403, so that the locking gear 4 cannot reverse its direction on its own, thus locking the turning angle of the equipment and providing users with safety and stability.

[0060] Step 5: When the user leans against the pneumatic headboard 101, pressure is applied to the pneumatic headboard 101. The bending plate 205 is under pressure and has a tendency to reverse. The disc spring 303 releases the elastic potential energy accumulated when the bending plate 205 rotates in "Step 3", applies pressure to the bending plate 205, and provides it with cushioning.

[0061] Step Six: When the user leaves, the mattress adaptively adjusts, the electromagnet 405 is activated to retract the slide column 402 into the ring 403, and the motor 304 rotates in the opposite direction to reset the pneumatic headrest 101.

[0062] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
