Description

Technical Field

[0001] The utility model relates to a mattress for intelligent bedding, in particular to a pressure monitoring pad and a mattress using the same. Background Art

[0002] Pressure sensor strips are increasingly being used in smart mattresses. By embedding these strips in different areas of the mattress, they form a distributed pressure monitoring network. When a sleeper lies on the mattress, their body weight applies pressure to the strips, which convert these pressure changes into electrical signals and transmit them to the mat control box. These electrical signals reflect the sleeper's pressure distribution on the mattress. The mat control box, a state-of-the-art technology, can then perform computational analysis based on the acquired electrical signal data to infer the current sleeping position, such as turning over, adjusting sleeping position, and sitting up. The main control box of the smart mattress connects to the mat control box and automatically adjusts the mattress's firmness, support, or temperature based on the sleeping position and pressure data it outputs, adapting to the sleeper's varying needs and preferences. By combining this with other sensor data, such as vital sign monitoring strips, the smart mattress system can also provide a comprehensive sleep quality assessment, helping users improve their sleep.

[0003] Current pressure sensing belts for detecting sleeping posture on the market have multiple pressure sensors. These pressure sensors are located at several points on the belt, while mattresses typically use a single or multiple discrete pressure sensing belts. Each pressure sensing belt has a limited monitoring area and can only monitor pressure changes at a single location, such as the shoulders or hips. Consequently, the pressure data is limited, making it difficult for the sleeping pad control box to accurately determine the user's sleeping position based on the acquired data. Furthermore, the carrier for the sensors on the pressure sensing belt is a plastic film, which has poor air permeability and comfort. Furthermore, the plastic film is not very soft, and the foreign body sensation it produces when pressed is strong and uncomfortable. The pressure sensing belt lacks an effective fixed mounting structure and is simply inserted into the outermost mattress cover and placed on the top surface of the mattress during installation. During use, due to repeated tossing or rolling of the mattress, the pressure sensing belt can easily move away from the originally designated monitoring area, affecting the accuracy of the sleeping posture monitoring data and causing errors in sleeping posture judgment. Utility Model Content

[0004] In order to solve the technical problems that the pressure sensing belt used on the existing mattress has a limited monitoring area, obtains little pressure data information, and the sleeping pad control box has difficulty in accurately judging the user's sleeping position, the utility model provides a pressure monitoring pad. The pressure monitoring pad can monitor the area continuously extending along the length of the mattress, has a wide monitoring range, and obtains rich pressure data information. The pressure data of more continuous areas can help the sleeping pad control box accurately calculate and analyze the current user's sleeping position on the mattress.

[0005] The present invention solves the technical problem by adopting a technical solution: a pressure monitoring pad, comprising a monitoring pad body provided with a pressure sensor, the pressure sensor being connected to a sleeping pad control box via a signal connection harness connected to the monitoring pad body, and the sleeping pad control box being connected to a main control box via a signal output harness. The monitoring pad body is characterized in that the monitoring pad body is an integral pad extending along the length of the mattress, and the integral pad is continuously provided with pressure sensors along its length to form a continuous detection area. By extending the integral pad along the length of the mattress and continuously provided with pressure sensors thereon, the pressure detection area is expanded, and a wider area can be continuously matched with more body parts. Compared with existing single or scattered pressure sensor strips that can only monitor and obtain scattered pressure data of a few body parts, the integral pad of the present invention has a wider and continuous monitoring area, can obtain more abundant pressure monitoring data, and thus enables the sleeping pad control box to perform accurate sleeping posture calculation and analysis, which helps to determine the user's current correct sleeping posture, helps the mattress to intelligently adjust to the different needs and preferences of the sleeper, and improves sleep quality.

[0006] As a further improvement and supplement to the above-mentioned technical solution, the present invention employs the following technical measures: the detection area includes a continuous detection working area from the front to the back of the integrated mattress, at least from the shoulders to the hips. This continuous detection working area monitors continuous pressure data from the shoulders to the hips, allowing the sleeping position pad control box to perform more accurate analysis and calculation based on this pressure data to determine the current sleeping position.

[0007] Preferably, the detection area includes a continuous detection work area from the shoulders to the legs, with the front and rear ends of the integrated pad corresponding to the shoulder and leg detection areas, respectively. By continuously detecting from the shoulders to the legs, especially by analyzing the contact between the legs and the mattress in combination with the leg pressure data, the leg posture is determined. By integrating the pressure data of the contact between other body parts and the monitoring pad body, the current sleeping posture can be more accurately calculated and analyzed.

[0008] Preferably, the monitoring pad body is made of a flexible, breathable, and moisture-absorbent fabric, and the pressure sensor is wrapped in the fabric, and the pressure sensor is a resistor sheet and / or a resistor wire. By making the monitoring pad body of a flexible, breathable, and moisture-absorbent fabric, the pressure monitoring pad has good flexibility, and combined with the bendability of the resistor sheet and / or the resistor wire, the monitoring pad body bends and fits the body part that is pressed during use, without any foreign body sensation, and the body feels comfortable and does not affect sleep and rest; at the same time, the fabric is also moisture-absorbent and breathable, and when lying for a long time, the mattress is pressed on the monitoring pad body, and the monitoring pad body will not generate heat accumulation and dampness due to the user's long-term inactivity. The monitoring pad body can remain dry, effectively protecting the internal sensor components while maintaining the comfort of the mattress.

[0009] A second object of the present invention is to provide a mattress comprising a mattress cover, a surrounding layer encased within the cover, and an inner layer enclosed by the surrounding layer, the mattress being equipped with a mattress master control box for intelligent adjustment. The mattress utilizes one of the aforementioned pressure monitoring pads, wherein the monitoring pad body is disposed within the top surface area of the mattress, inside the cover, and removably connected to the inner surface of the cover. The signal connection harness is routed between the cover and the inner layer and connected to the sleeping position pad control box secured to the surrounding layer. The signal output harness extends through the surrounding layer and connects to the mattress master control box. By disposing the aforementioned pressure monitoring pad within the upwardly directed top surface area of the mattress, the pressure monitoring pad continuously monitors pressure along the length of the mattress, thereby acquiring richer regional pressure monitoring data. This allows the sleeping position pad control box to accurately calculate and analyze the user's current sleeping position, thereby assisting the mattress master control box in intelligently adjusting features such as mattress firmness, support, or temperature, as well as other sleep-enhancing features, thereby enhancing the mattress's sleep-aiding effect. The monitoring pad body is arranged on the inside of the mattress cover and is detachably connected to its inner surface. Not only can the monitoring pad body be packaged and transported separately and put on the mattress when needed, but it is also convenient for subsequent replacement and iteration by removing the old monitoring pad body and replacing it with a new one.

[0010] Preferably, the mattress cover comprises an inner mattress cover that wraps the inner layer and an outer fabric layer, with the monitoring pad body disposed within the inner mattress cover and removably connected to its inner surface. The mattress cover employs a two-layer structure, with the inner mattress cover wrapping and integrating the surrounding layer and inner layer, and connecting and positioning the monitoring pad body. The outer fabric layer provides comfort for the user lying on the mattress.

[0011] Preferably, the detachable connection is a double-ended zipper structure, with matching zippers provided on the monitoring pad body and the mattress inner cover. The double-ended zipper allows for a detachable connection between the monitoring pad body and the mattress inner cover. The double-ended zipper provides a wider opening for quick access and installation of the monitoring pad body, and is also more durable.

[0012] Preferably, the signal connection harness is locked with Velcro and routed against the inner surface of the mattress inner cover. The inner surface of the mattress inner cover is provided with a mating surface that matches the Velcro. This prevents the signal connection harness from shifting during transportation, handling, and subsequent use of the mattress, which could cause discomfort and a foreign body sensation to the person lying on the mattress, affecting their comfort. Furthermore, the locked signal connection harness prevents displacement that could cause the harness to pull, affecting the normal transmission of the pressure signal.

[0013] Preferably, the inner side of the surrounding layer defines a cavity with an opening corresponding to the sleeping position pad control box. The sleeping position pad control box is embedded in the cavity and tightly secured to the surrounding layer. A through hole is provided in the surrounding layer on one side of the cavity, into which an adapter box is embedded. The signal output wiring harness passes through a wiring channel provided in the adapter box and extends out of the surrounding layer. The sleeping position control box is embedded and secured in the cavity defined in the surrounding layer, with the surrounding layer providing a concealed position. The surrounding layer also defines a through hole for the adapter box to be embedded and mounted. The adapter box facilitates connection of the air supply line for the airbags installed within the mattress to an air source. The wiring channel provided in the adapter box allows the signal output wiring harness to extend through the surrounding layer and connect to the main control box of the smart mattress.

[0014] Preferably, a wiring groove for the signal output harness is formed on the surface of the surrounding layer between the cavity and the through hole, with the two ends of the wiring groove connecting the cavity and the through hole respectively. After exiting from one end of the sleeping pad control box, the signal output harness is routed within the wiring groove to the through hole, then passes through a wiring channel provided on the adapter box embedded in the through hole and extends out of the surrounding layer.

[0015] The beneficial technical effects of the present invention are as follows: the main body of the pressure monitoring pad is an integrated pad extending along the length of the mattress, and pressure sensors are continuously arranged on it, expanding the area range of pressure detection to obtain richer pressure monitoring data, so that the sleeping position pad control box can accurately calculate and analyze the sleeping position, thereby helping the mattress to intelligently adjust to the different needs and preferences of the sleeper and improve sleep quality. A mattress using the pressure monitoring pad can help the mattress main control box intelligently adjust the functional characteristics of the mattress to improve sleep and enhance the sleep-aiding effect of the mattress. The monitoring pad body is detachably connected to the inner surface of the mattress cover, which is convenient for separate packaging, transportation and subsequent assembly. The detachable connection allows the monitoring pad body to be replaced without changing the mattress. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0023] like Figure 1 As shown, Example 1 is a pressure monitoring pad, comprising a monitoring pad main body 1 provided with a pressure sensor, the pressure sensor is connected to a sleeping pad control box 3 through a signal connection harness 2 connected to the monitoring pad main body 1, and the sleeping pad control box 3 is connected to a main control box of the mattress (not shown) through a signal output harness 4, the monitoring pad main body 1 is an integrated pad extending along the length direction of the mattress, and the integrated pad is continuously provided with pressure sensors along its length direction to form a continuous detection area, the detection area includes at least a continuous detection working area from the shoulder to the buttocks from the front end to the rear end of the integrated pad, and in this embodiment, the detection area preferably includes a continuous detection working area from the shoulder to the leg, and the front and rear ends of the integrated pad correspond to the detection of the shoulder and leg respectively, and the detection of the leg during use can be a pressure detection of the thigh position or a pressure detection of the thigh and the calf.

[0024] The integrated pad extending along the length of the mattress in this embodiment, along with the pressure sensors continuously positioned thereon, expands the pressure detection area of the monitoring pad's main body. By continuously matching a wider area and more body parts, compared to previous single or scattered pressure sensing strips that could only monitor and obtain sporadic pressure data on individual body parts, the integrated pad in this embodiment has a wider and continuous monitoring area, enabling it to acquire more and richer pressure monitoring data. This allows the sleeping pad control box to accurately calculate and analyze sleeping postures, thereby accurately determining the user's current sleeping position. For example, continuous pressure data along the length of the monitoring pad's main body can determine that the shoulder to hip position is consistently in contact with the mattress, indicating a reclining sleeping position. Simultaneously, pressure data along the width of the vertical length helps determine the contact area between the body and the mattress, further determining whether the body is lying flat or sideways. The correct sleeping posture information and pressure monitoring data are then transmitted to the intelligent mattress main control box via a signal output harness, enabling the mattress to intelligently adjust to the sleeper's different needs and preferences, improving sleep quality.

[0025] Furthermore, the monitoring pad body 1 is made of a flexible, breathable and moisture-absorbent fabric, and the pressure sensor is wrapped in the fabric. The pressure sensor is a resistor, or a resistance wire, or a combination of a resistor and a resistance wire (not shown in the figure). The resistance wire and the resistor are soft and can be bent and deformed according to the existing technology. During use, the monitoring pad body bends to fit the body part that is pressed, without any foreign body sensation, and the body feels comfortable without affecting sleep and rest. At the same time, the fabric is also moisture-absorbent and breathable. When lying for a long time, the mattress is pressed on the monitoring pad body, and the monitoring pad body will not generate heat accumulation and dampness due to the user's long-term inactivity, so as to keep dry, protect the internal sensor components and maintain the comfort of the mattress. In actual use, the monitoring pad body can be made of common natural fabrics or chemical fiber materials that are flexible, moisture-absorbent and breathable.

[0026] like Figures 2 to 5 As shown, Example 2 is a mattress, comprising a mattress cover, a circle of edge layer 6 covered in the mattress cover, an inner layer 8 wrapped by the edge layer 6, and a bottom layer 7 supporting the inner layer, the inner layer 8 comprising a massage layer 8-1 and a support layer 8-2 stacked up and down, the mattress is also provided with a mattress main control box for intelligent adjustment, the mattress described in this embodiment uses the pressure monitoring pad described in Example 1, comprising a monitoring pad body 1 and a sleeping position pad control box 3 connected by a signal connection harness 2, the sleeping position pad control box 3 is connected to the mattress main control box through a signal output harness 4, wherein the monitoring pad body 1 is arranged on the inner side of the mattress cover in the top surface area of the mattress and is detachably connected to the inner surface of the mattress cover, the signal connection harness 2 is routed between the mattress cover and the inner layer 8 and is connected to the sleeping position pad control box 3 fixed on the edge layer 6, the signal output harness 4 extends through the edge layer 6 to connect to the mattress main control box.

[0027] A mattress using the pressure monitoring pad described in Example 1 can transmit accurate sleeping posture information and pressure data to the mattress's main control box, enabling the main control box to intelligently adjust features such as mattress firmness, support, and temperature, as well as other sleep-enhancing features, thereby enhancing the mattress's sleep-inducing effects. Because the monitoring pad's main body is detachably attached to the inner surface of the mattress cover, it can be packaged and transported separately and attached to the mattress upon use. It also facilitates subsequent replacements by removing the old monitoring pad and replacing it with a new one.

[0028] Furthermore, the mattress cover includes an inner mattress cover 9 and an outer fabric layer (not shown). The monitoring pad body 1 is disposed within the mattress cover 9 and removably connected to its inner surface. In this embodiment, the removable connection is a double-ended zipper structure 11, with matching zippers provided on the edge of the monitoring pad body 1 and the mattress cover 9. The inner mattress cover is used to wrap and integrate the surrounding layer and inner layer, and connect and position the monitoring pad body. The outer fabric layer provides a comfortable feeling for the user lying on the mattress. The double-ended zipper allows for a larger opening for quick and easy access to the monitoring pad body, and is also more durable.

[0029] Furthermore, the signal connection harness 2 is locked and routed against the inner surface of the mattress inner cover 9 via Velcro 5. The inner surface of the mattress inner cover 9 is provided with a mating surface that mates with the Velcro 5. The Velcro is used to prevent the signal connection harness from shifting during transportation, handling, and subsequent use of the mattress, which could cause discomfort and a foreign body sensation to the person lying on the mattress, affecting their comfort. Furthermore, by locking the signal connection harness against the inner surface of the mattress inner cover via Velcro, it can prevent the harness from shifting and pulling, which could affect the normal transmission of the pressure signal.

[0030] Furthermore, a cavity 6-1 with an opening that matches the sleeping pad control box 3 is opened on the inner side surface of the surrounding layer 6. The sleeping pad control box 3 is embedded in the cavity and tightly fixed on the surrounding layer 6. A through hole 6-2 is opened in the surrounding layer 6 on one side of the cavity, and an adapter box 10 is embedded in it. A wiring groove 6-3 for routing the signal output harness 4 is also opened on the surface of the surrounding layer 6 between the cavity 6-1 and the through hole 6-2. The two ends of the wiring groove 6-3 are respectively connected to the cavity 6-1 and the through hole 6-2. The signal output harness 4 is routed to the through hole 6-2, passes through the routing channel 10-1 set on the adapter box 10, and extends out of the surrounding layer 6 to connect to the mattress main control box.

[0031] The sleeping posture control box is embedded in the fixed surrounding layer and is hidden in the surrounding layer for positioning. The through hole opened on the surrounding layer is embedded in the installation of the adapter box. The adapter box can facilitate the connection of the air supply source for the air bag inside the mattress. The two sections of air pipes connected at the inner and outer ends of the adapter box are independent of each other and do not affect each other. The air pipe connected at the outer end can be used as an optional configuration. With the help of the wiring channel reserved on the adapter box, the signal output harness can pass through the surrounding layer and extend to connect to the main control box of the mattress.
