Further, because of the first row The first cylindrical air cells 122 of A1 are in communication with each other, so that the first air tubes 150 need only be connected to one of the first cylindrical air bags 122 of each of the first rows A1 to connect all of the first cylindrical air bags 122. Similarly, since the second cylindrical airbags 124 of the second row A2 are in communication with each other, the second air pipe 160 only needs to be connected to one of the second cylindrical airbags 124 of each of the second rows A2 to connect all the second cylinders.

FIG. 8 is a side elevational view of the pressure sensing airbag module of FIG. 7 showing the plenum balloon layer. Please refer to FIG. 7 and FIG. 8. FIG. 7 only shows a partial pressure equalization airbag layer 120 to clearly show the plenum airbag layer 110. In the present embodiment, the plenum filter layer 110 includes a fulcrum 112 disposed in the plenum layer 110 and connected to the upper wall 114 and the lower wall 116 of the plenum layer 110. In detail, the surged airbag layer 110 is a block-shaped independent airbag. After the general airbag is inflated, there is usually a phenomenon in which the central portion protrudes from the surrounding portion. This phenomenon causes the top surface S1 and the pressure equalization airbag layer 120 disposed on the surged airbag layer 110. The pressure sensing layer 130 senses the sensing result of the pressure applied to the plurality of portions of the pressure equalizing airbag layer 120, and the bottom surface S3 of the surged airbag layer 110 is easily protruded from the ground due to the central portion. The contact area is reduced, and the tilt is easily generated.
因此，在本實施例中，穩壓氣囊層110藉由三條支帶112分別連接穩壓氣囊層110的上壁114與下壁116，以使穩壓氣囊層110的頂面S1與底面S3較為平坦，其中支帶112分別對應於第一筒狀氣囊122與第二筒狀氣囊124的連接處，以使各第一筒狀氣囊122與各第二筒狀氣囊124分別位在對應的兩支帶112之間。據此，配置於穩壓氣囊層110的頂面S1上的壓力感測層130與均壓氣囊層120的第一筒狀氣囊122與第二筒狀氣囊124的接觸面積更為平均，以提高感測結果的準確度，且穩壓氣囊層110的底面S3與地面的接觸面積提高而增加氣墊裝置10的穩定性。 Therefore, in the present embodiment, the plenum layer 110 is connected to the upper wall 114 and the lower wall 116 of the plenum layer 110 by three strips 112, so that the top surface S1 and the bottom surface S3 of the plenum layer 110 are relatively Flat, wherein the support belts 112 respectively correspond to the joints of the first cylindrical airbag 122 and the second tubular airbag 124, so that the first cylindrical airbags 122 and the second tubular airbags 124 are respectively located in the corresponding two branches. Between 112. Accordingly, the contact area of the first tubular airbag 122 and the second cylindrical airbag 124 of the pressure sensing layer 130 disposed on the top surface S1 of the surged airbag layer 110 and the pressure equalized airbag layer 120 is more averaged to improve The accuracy of the sensing result is increased, and the contact area of the bottom surface S3 of the surged airbag layer 110 with the ground is increased to increase the stability of the air cushion device 10.
然而，在其他實施例中，穩壓氣囊層110可具有一條或多條支帶112，本發明不限制支帶112的數量。在其他未繪示的實施例中，連接穩壓氣囊層110的上壁114與下壁116的支帶亦可為環狀支帶。環狀支帶的兩側連接上壁114與下壁116，以達上述的功能。環狀支帶本身形成環狀，使得穩壓氣囊層110的結構的俯視圖類似於「回」字型，其中「回」字型的外圈為穩壓氣囊層110的側壁，而「回」字型的內圈為環狀支帶，但本發明並不限制支帶的種類、形狀與設置與否。此外，支帶112上具有多個孔洞(未繪示)，當穩壓氣囊層110填充氣體時，穩壓氣囊層110雖以支帶112分隔成多個空間，但氣體會經由孔洞流動至穩壓氣囊層 110的各空間，以使整個穩壓氣囊層110具有相同氣壓。 However, in other embodiments, the surged bladder layer 110 can have one or more straps 112, and the present invention does not limit the number of straps 112. In other embodiments not shown, the strap connecting the upper wall 114 and the lower wall 116 of the surge tank layer 110 may also be an annular strap. Both sides of the annular branch are connected to the upper wall 114 and the lower wall 116 to achieve the above functions. The annular band itself forms a ring shape, so that the top view of the structure of the voltage-regulating airbag layer 110 is similar to the "back" shape, wherein the outer ring of the "return" type is the side wall of the surged airbag layer 110, and the word "return" The inner ring of the type is an annular band, but the invention does not limit the type, shape and setting of the band. In addition, the support belt 112 has a plurality of holes (not shown). When the surge tank layer 110 is filled with gas, the surge tank layer 110 is divided into a plurality of spaces by the branch 112, but the gas flows to the stable through the holes. Pressure airbag layer Each space of 110 is such that the entire plenum panel 110 has the same air pressure.
圖9是圖2的壓力感測層的壓力感測電路示意圖。圖10是圖9的壓力感測元件的示意圖。請參考圖9至圖10，在本實施例中，壓力感測層130包括多個壓力感測元件132，配置於對應的第一筒狀氣囊122以及對應的第二筒狀氣囊124的底部122a與124a與穩壓氣囊層110之間，如圖4與圖5所示。壓力感測元件132可對應於每一第一筒狀氣囊122以及每一第二筒狀氣囊124，亦可選擇性的對應於部分的第一筒狀氣囊122以及第二筒狀氣囊124，用以感測均壓氣囊層120的多個部位所承受的壓力。壓力感測元件132排列成壓力感測陣列，並經由連接線134互相連接。 9 is a schematic diagram of a pressure sensing circuit of the pressure sensing layer of FIG. 2. Figure 10 is a schematic illustration of the pressure sensing element of Figure 9. Referring to FIG. 9 to FIG. 10 , in the embodiment, the pressure sensing layer 130 includes a plurality of pressure sensing elements 132 disposed on the bottom portion 122 a of the corresponding first cylindrical air bag 122 and the corresponding second cylindrical air bag 124 . Between 124a and the tempered airbag layer 110, as shown in FIGS. 4 and 5. The pressure sensing element 132 may correspond to each of the first cylindrical airbags 122 and each of the second tubular airbags 124, and may also selectively correspond to a portion of the first cylindrical airbag 122 and the second tubular airbag 124. The pressure experienced by the plurality of portions of the pressure equalized airbag layer 120 is sensed. The pressure sensing elements 132 are arranged in a pressure sensing array and are interconnected via a connecting line 134.
隨著時代的進步，一些電子產品，例如是看護床墊，會在內部配置壓力感測陣列，以便偵測或記錄使用者的睡臥狀態。因此，應用軟性電子零組件技術的軟性陣列感測元件因應而生，而本實施例的壓力感測元件132即為上述的軟性陣列感測元件。壓力感測元件132採用壓阻式感測技術，其在上下基板132a的內側分別依序堆疊上下電極層132b以及上下壓阻感應層132c，並在上下基板132a的四周佈置壓感膠132d，以使上下基板132a黏合。上下基板132a使用柔軟的塑膠材料，以使壓力感測元件132具有可撓曲的特性，並且讓上下壓阻感應層132c可以相互接觸。 With the advancement of the times, some electronic products, such as nursing mattresses, are internally equipped with a pressure sensing array to detect or record the user's sleep state. Therefore, the soft array sensing element using the soft electronic component technology is responsive, and the pressure sensing element 132 of the present embodiment is the above-described soft array sensing element. The pressure sensing element 132 adopts a piezoresistive sensing technology, and sequentially stacks the upper and lower electrode layers 132b and the upper and lower piezoresistive sensing layers 132c on the inner side of the upper and lower substrates 132a, and arranges the pressure sensitive adhesive 132d around the upper and lower substrates 132a. The upper and lower substrates 132a are bonded. The upper and lower substrates 132a are made of a soft plastic material so that the pressure sensing element 132 has a flexible property, and the upper and lower piezoresistive sensing layers 132c can be brought into contact with each other.
壓阻感應層132c為一種壓阻材料，其利用奈米分散技術將奈米導電粒子均勻分散於高分子聚合物其中，以形成一個具有線性反應的壓阻式複合材料。因此，奈米導電粒子使壓阻感應層 132c的表面為可微量變形的粗糙表面，以在壓力感測元件132在受到正向力施加時，藉由粗糙表面產生的微量變形，使上下壓阻感應層132c的接觸面積增加。具體而言，受壓變形後的壓阻感應層132c會以電阻定律(R=ρ L/A)而產生電阻值(R)變化。當壓力感測元件132受壓時，壓阻感應層132c因受壓而產生微量變形，使得壓阻感應層132c的截面積(A)增加而導致輸出電阻值降低。此時，上下電極層132b感測電阻值變化並透過後端系統(例如是後述的控制模組14的感測壓力感測電路14a以及可視化介面16)進行電阻值變化的紀錄與判斷。因此，上下壓阻感應層132c能經由所施加的正向力大小不同而改變兩者之間的接觸程度，使得所感測到的電阻值大小也會改變。當壓力移除以後，上下壓阻感應層132c的微量變形可迅速回覆原狀，因此不會產生明顯的遲滯現象，同時具有良好的線性度以及重現性。 The piezoresistive sensing layer 132c is a piezoresistive material which uniformly disperses nano conductive particles in a high molecular polymer by a nano-dispersion technique to form a piezoresistive composite material having a linear reaction. Therefore, the nano-conductive particles make the piezoresistive sensing layer The surface of the 132c is a slightly deformable rough surface to increase the contact area of the upper and lower piezoresistive sensing layers 132c when the pressure sensing element 132 is applied by a positive force with a slight deformation caused by the rough surface. Specifically, the piezoresistive sensing layer 132c after the pressure deformation generates a resistance value (R) change by the law of resistance (R = ρ L / A). When the pressure sensing element 132 is pressed, the piezoresistive sensing layer 132c is slightly deformed by the pressure, so that the cross-sectional area (A) of the piezoresistive sensing layer 132c is increased to cause the output resistance value to decrease. At this time, the upper and lower electrode layers 132b sense the change in the resistance value and record and judge the change in the resistance value through the back end system (for example, the sensing pressure sensing circuit 14a and the visualization interface 16 of the control module 14 to be described later). Therefore, the upper and lower piezoresistive sensing layers 132c can change the degree of contact between the two via the magnitude of the applied positive force, so that the magnitude of the sensed resistance value also changes. When the pressure is removed, the slight deformation of the upper and lower piezoresistive sensing layers 132c can be quickly restored to the original state, so that no significant hysteresis occurs, and at the same time, good linearity and reproducibility are obtained.
由此類壓力感測元件132所組成的軟性陣列感測具有結構簡單、易於使用、輕薄、可撓曲、抗摔、低耗電等特點，並且可利用網版印刷技術印刷至基板132a上。然而，壓力感測元件132必需撘配壓力感測電路才能實現它的效能。具體而言，在本實施例中，氣墊裝置10更包括控制模組14。控制模組14連接壓力感測層130，其中壓力感測層130感測均壓氣囊層120的部位所承受的壓力，而控制模組14接收壓力感測層130的一感測結果。控制模組14包括壓力感測電路14a，壓力感測電路14a如圖9所示，其主要透過類比前端訊號處理電路(analog frontend)撘配微控制 器包括列控制器(row controller)與行控制器(column controller)所輸出的列控制訊號(row control signal)及行控制訊號(column control signal)來讀取壓力感測元件132的電阻值，再經由類比數位轉換器(analog to digit converter，ADC)將電阻值的類比數值轉換到數位資料。接著，將數位資料透過微控制器(micro controller)進行數位訊號處理後，將資料直接透過微控制器傳送到RS232訊號傳送接收轉換電路。 The soft array sensing composed of the pressure sensing element 132 of this type has the characteristics of simple structure, easy to use, light weight, flexibility, drop resistance, low power consumption, and the like, and can be printed onto the substrate 132a by screen printing technology. However, the pressure sensing element 132 must be equipped with a pressure sensing circuit to achieve its performance. Specifically, in the embodiment, the air cushion device 10 further includes a control module 14 . The control module 14 is connected to the pressure sensing layer 130, wherein the pressure sensing layer 130 senses the pressure of the portion of the pressure equalizing airbag layer 120, and the control module 14 receives a sensing result of the pressure sensing layer 130. The control module 14 includes a pressure sensing circuit 14a, and the pressure sensing circuit 14a is shown in FIG. 9 mainly through an analog front end signal processing circuit (analog frontend) The device includes a row control signal and a column control signal outputted by a row controller and a column controller to read the resistance value of the pressure sensing element 132, and then The analog value of the resistance value is converted to digital data via an analog to digit converter (ADC). Then, the digital data is processed by the digital controller through the micro controller, and then the data is directly transmitted to the RS232 signal transmission and reception conversion circuit through the microcontroller.
此外，在本實施例中，氣墊裝置10更包括可視化介面16。可視化介面16連接控制模組14，用以顯示控制模組14所接收的壓力感測層130的感測結果。具體來說，可視化介面16連接上述的RS232訊號傳送接收轉換電路。當數位資料透過微控制器進行數位訊號處理，並直接透過微控制器傳送到RS232訊號傳送接收轉換電路之後，RS232訊號傳送接收轉換電路之將資料輸出到可視化介面16，用以顯示壓力感測層130的壓力感測元件132所排列而成的壓力感測陣列的壓力分布圖形。 Moreover, in the present embodiment, the air cushion device 10 further includes a visualization interface 16. The visual interface 16 is connected to the control module 14 for displaying the sensing result of the pressure sensing layer 130 received by the control module 14 . Specifically, the visualization interface 16 is connected to the RS232 signal transmission and reception conversion circuit described above. When the digital data is processed by the digital signal through the microcontroller and directly transmitted to the RS232 signal transmission and reception conversion circuit through the microcontroller, the RS232 signal transmission and reception conversion circuit outputs the data to the visualization interface 16 for displaying the pressure sensing layer. The pressure sensing pattern of the pressure sensing array in which the pressure sensing elements 132 of 130 are arranged.
上述的控制裝置14的壓力感測電路14a與可視化介面16的規格與種類如下：輸入電源為電壓是5伏特(V)而電流是0.5安培(A)的直流電(Direct Current，DC)或是直接透過USB接線使用USB電源；數位輸出資料為標準RS232輸出介面，其數位傳輸速率(鮑率(baud rate))為38400bps(bit per second)或者9600bps；壓力感測電路14a最多可讀取排列成32×32陣列的1024個壓力感測元件132，而感測元件介面(sensor interface)為 2.54連接器(connector)，其為單排排座(母座)。可視化介面16例如是筆記型電腦(notebook，NB)或是個人電腦(personal computer，PC)裝置等人機介面，用以顯示壓力感測層130的壓力分布圖形。然而，上述的壓力感測電路14a的規格與可視化介面16的種類僅為本發明的其中一實施例，本發明不以此為限制。 The specifications and types of the pressure sensing circuit 14a and the visualization interface 16 of the control device 14 described above are as follows: the input power source is a voltage of 5 volts (V) and the current is 0.5 amps (A) of direct current (DC) or direct Use USB power supply through USB connection; digital output data is standard RS232 output interface, its digital transmission rate (baud rate) is 38400bps (bit per second) or 9600bps; pressure sensing circuit 14a can be read up to 32 1024 arrays of 1024 pressure sensing elements 132, and the sensor interface is 2.54 connector, which is a single row of seats (female). The visualization interface 16 is, for example, a human computer interface such as a notebook (NB) or a personal computer (PC) device for displaying the pressure distribution pattern of the pressure sensing layer 130. However, the specification of the pressure sensing circuit 14a and the type of the visualization interface 16 are only one embodiment of the present invention, and the present invention is not limited thereto.
另一方面，由於本實施例的壓力感測元件132為軟性的壓阻式感測元件，且其上下壓阻感應層132c能經由所施加的正向力大小不同而改變電阻值，因此當壓力感測層130配置於穩壓氣囊層110與均壓氣囊層120之間時，壓力感測元件132的電阻值會受到均壓氣囊層120的重量與穩壓氣囊層110的氣壓的影響。具體來說，壓力感測層130是經由對應於均壓氣囊層120承受壓力的多個部位的壓力感測元件132的電阻值變化來得知壓力集中點。因此，在均壓氣囊層120未承受壓力之前，壓力感測層130承受固定重量(例如是均壓氣囊層120的重量)，且穩壓氣囊層110的氣壓均勻，使得每一壓力感測元件132具有相同的電阻起始值與感測特性。此時，每一壓力感測元件132的起始電阻值與感測特性受到壓力感測元件132所承載的重量(例如是均壓氣囊層120的重量)與穩壓氣囊層110的氣壓的影響。 On the other hand, since the pressure sensing element 132 of the present embodiment is a soft piezoresistive sensing element, and the upper and lower piezoresistive sensing layers 132c can change the resistance value via the magnitude of the applied positive force, thus the pressure When the sensing layer 130 is disposed between the surge tank layer 110 and the pressure equalization airbag layer 120, the resistance value of the pressure sensing element 132 is affected by the weight of the pressure equalization airbag layer 120 and the air pressure of the surge tank layer 110. Specifically, the pressure sensing layer 130 is a pressure concentration point obtained by a change in resistance value of the pressure sensing element 132 corresponding to a plurality of portions of the pressure equalizing airbag layer 120 that are subjected to pressure. Therefore, before the pressure equalizing airbag layer 120 is not under pressure, the pressure sensing layer 130 is subjected to a fixed weight (for example, the weight of the pressure equalizing airbag layer 120), and the air pressure of the surged airbag layer 110 is uniform, so that each pressure sensing element 132 has the same resistance starting and sensing characteristics. At this time, the initial resistance value and the sensing characteristic of each pressure sensing element 132 are affected by the weight carried by the pressure sensing element 132 (for example, the weight of the pressure equalizing airbag layer 120) and the air pressure of the surged airbag layer 110. .
圖11是圖10的壓力感測元件在承受不同重量以及不同穩壓氣囊層的氣壓下的特性曲線示意圖。請參考圖11，圖11繪示壓力感測元件132在承受不同重量以及不同穩壓氣囊層的氣壓下的特性曲線示意圖。每一條曲線代表壓力感測元件132在穩壓氣 囊層110處於各個不同的氣壓下，其承受不同的重量(單位：公克)時所對應的電導值(conductivity)，其中橫軸為重量，縱軸為電導值。此外，圖11下半部的曲線群繪示壓力感測元件132在不同的穩壓氣囊層110的壓力下，承受不同重量時的電阻值的倒數(1/R)，而上半部的曲線群繪示壓力感測元件132在不同的穩壓氣囊層110的壓力下，承受不同重量以及未承受重量時的電阻值的差值倒數(1/△R)。 FIG. 11 is a schematic diagram showing the characteristic curves of the pressure sensing element of FIG. 10 under different air pressures and different pressure-regulating airbag layers. Please refer to FIG. 11. FIG. 11 is a schematic diagram showing the characteristic curves of the pressure sensing element 132 under different air pressures and different pressure-regulating airbag layers. Each curve represents the pressure sensing element 132 in the regulated gas The envelope layer 110 is at a different pressure and corresponds to a conductivity (unit: gram) corresponding to the conductance, wherein the horizontal axis is the weight and the vertical axis is the conductance value. In addition, the curve group in the lower half of FIG. 11 shows the reciprocal (1/R) of the resistance value of the pressure sensing element 132 under different pressures of the pressure-regulating airbag layer 110 under different pressures, and the curve of the upper half. The group shows the reciprocal (1/ΔR) of the difference in resistance values of the pressure sensing element 132 under different pressures of the surged airbag layer 110 under different weights and without being subjected to weight.
由此可知，壓力感測元件132可藉由調整穩壓氣囊層110的氣壓而調整其感測特性。當穩壓氣囊層110的氣壓固定之後，由於未承受壓力的均壓氣囊層120所提供給壓力感測層130的重量也固定，故壓力感測元件132的起始電阻值與感測特性也因而固定(其感測特性例如圖11的其中一條曲線)。因此，在均壓氣囊層120未承受額外壓力之前，各壓力感測元件132的電阻值相同。當均壓氣囊層120的多個部位承受壓力時，對應於承受壓力的那些部位的壓力感測元件132在固定的感測特性下依據所承受的壓力值而改變其電阻值，並藉由量測各壓力感測元件132的電阻值變化而得知承受壓力的部位的位置與其重量，並將此結果傳送至圖9的控制裝置14的壓力感測電路14a與可視化介面16，以判定均壓氣囊層120上的壓力集中點。 It can be seen that the pressure sensing element 132 can adjust its sensing characteristics by adjusting the air pressure of the plenum balloon layer 110. After the air pressure of the surge tank layer 110 is fixed, since the weight of the pressure sensing layer 130 provided by the pressure-free airbag layer 120 that is not subjected to pressure is also fixed, the initial resistance value and the sensing characteristic of the pressure sensing element 132 are also It is thus fixed (its sensing characteristics such as one of the curves of Fig. 11). Therefore, the resistance values of the respective pressure sensing elements 132 are the same before the pressure equalizing airbag layer 120 is subjected to additional pressure. When a plurality of portions of the pressure equalization airbag layer 120 are subjected to pressure, the pressure sensing element 132 corresponding to those portions subjected to the pressure changes its resistance value according to the pressure value under a fixed sensing characteristic, and by the amount The resistance value of each pressure sensing element 132 is measured to know the position of the pressure-bearing portion and its weight, and the result is transmitted to the pressure sensing circuit 14a and the visualization interface 16 of the control device 14 of FIG. 9 to determine the voltage equalization. The pressure concentration point on the airbag layer 120.
另外，由於壓力感測元件132會受到正向力(重量)的影響而改變電阻值，因此壓力感測元件132除了可以藉由電阻值變化來感測壓力集中的位置之外，還可以用以量測總重量，例如 是量測病人的體重。量測方式例如是使用者(病人)躺在氣墊裝置10的均壓氣囊層120上，以使各個壓力感測元件132經由承受壓力而改變電阻值，並藉由電阻值變化而得知各壓力感測元件132所對應的均壓氣囊層120的部位所承受的重量，而對應於每一電阻值差值而得的重量的總和即為使用者的重量。 In addition, since the pressure sensing element 132 is affected by the positive force (weight) and changes the resistance value, the pressure sensing element 132 can be used in addition to sensing the position of the pressure concentration by the resistance value change. Measure the total weight, for example It is measuring the weight of the patient. The measuring method is, for example, that the user (patient) lies on the pressure equalizing airbag layer 120 of the air cushion device 10, so that each pressure sensing element 132 changes the resistance value by withstanding the pressure, and the pressure is known by the resistance value change. The weight of the portion of the pressure equalizing airbag layer 120 corresponding to the sensing element 132 is received, and the sum of the weights corresponding to the difference in resistance values is the weight of the user.

Referring to FIG. 4, FIG. 5 and FIG. 13, in the embodiment, the air cushion device 10 includes an air module 18. The inflatable module 18 is connected to the pressure equalized airbag layer 120 and the control module 14. After the control module 14 receives the sensing result of the pressure sensing layer 130, the control module 14 The inflating module 18 is controlled by the sensing result of the pressure sensing layer 130 to adjust the air pressure of the pressure equalizing airbag layer 120 by the inflating module 18. The air module 18 is connected to the first air tube 150, the second air tube 160 and the third air tube 170, and the control module 14 can control the air module 18 to inflate or release the first air tube 150, the second air tube 160 and the third air tube 170. The gas is controlled, and the first gas valve 152, the second gas valve 162, and the third gas valve 172 are controlled to be opened or closed.
在本實施例中，充氣模組18經由第三氣管170與第三氣閥172而調整穩壓氣囊層110的氣壓，進而固定壓力感測層130的感測特性。當均壓氣囊層120的部位承受壓力，例如是使用者躺在均壓氣囊層120上時，壓力感測層130藉由壓力感測元件132感測承受壓力的那些部位的位置與壓力值，並經由圖9的壓力感測電路14a將感測結果傳送到可視化介面16，以清楚得知均壓氣囊層120的壓力集中點的位置與壓力值。控制模組14依據壓力感測層130的感測結果而控制充氣模組18，包括控制對應於承受壓力的部位的第一筒狀氣囊122或者第二筒狀氣囊124所連接的第一氣閥152或第二氣閥162，以使對應的第一氣閥152或第二氣閥162開啟。因此，充氣模組18經由第一氣管150或第二氣管160對承受壓力的第一筒狀氣囊122或者第二筒狀氣囊124進行充氣或放氣，以調整均壓氣囊層120承受壓力的那些部位所對應的第一筒狀氣囊122或者第二筒狀氣囊124的氣壓，使得均壓氣囊層120的那些部位所承受的壓力因而分散。據此，氣墊裝置10具有較佳的舒適感。 In the present embodiment, the inflator module 18 adjusts the air pressure of the surge tank layer 110 via the third air tube 170 and the third air valve 172, thereby fixing the sensing characteristics of the pressure sensing layer 130. When the portion of the pressure equalization airbag layer 120 is subjected to pressure, for example, when the user lies on the pressure equalization airbag layer 120, the pressure sensing layer 130 senses the position and pressure value of those portions subjected to the pressure by the pressure sensing element 132. The sensing result is transmitted to the visualization interface 16 via the pressure sensing circuit 14a of FIG. 9 to clearly know the position and pressure value of the pressure concentration point of the pressure equalization airbag layer 120.

The air pressure of the first cylindrical air bag 122 or the second cylindrical air bag 124 corresponding to the portion causes the pressure applied to those portions of the pressure equalizing air bag layer 120 to be dispersed. Accordingly, the air cushion device 10 has a better comfort.
圖14是圖3的壓力感測氣囊模組的壓力感測示意圖。圖 15繪示圖14的壓力感測氣囊模組的承重感測流程圖。圖14繪示壓力感測氣囊模組100承受重量W並藉由壓力感測層130感測壓力值的示意圖，其中壓力感測層130僅以對應於均壓氣囊層120的部分第二筒狀氣囊124的壓力感測元件132與其量測結果為例。請參考圖14與圖15，在本實施例中，以經由氣墊裝置10感測承重的承重感測方法包括下列步驟。首先，藉由壓力感測氣囊模組100承受重量W。接著，增加穩壓氣囊層110的壓力，以將穩壓氣囊層110固定於較高的壓力值，例如是壓力值大於1(PSI)。當穩壓氣囊層110處於固定的壓力值時，藉由壓力感測氣囊模組100的壓力感測層130量測各點承受的壓力值，如同圖14的輸出結果，以經由累加各點的壓力值而得到壓力總和。 14 is a schematic view of pressure sensing of the pressure sensing airbag module of FIG. 3. Figure 15 is a flow chart showing the load sensing of the pressure sensing airbag module of FIG. 14 is a schematic diagram of the pressure sensing airbag module 100 receiving the weight W and sensing the pressure value by the pressure sensing layer 130, wherein the pressure sensing layer 130 only has a second cylindrical shape corresponding to the pressure equalizing airbag layer 120. The pressure sensing element 132 of the air bag 124 and its measurement result are exemplified. Referring to FIG. 14 and FIG. 15, in the present embodiment, the load bearing sensing method for sensing the load bearing via the air cushion device 10 includes the following steps. First, the airbag module 100 is subjected to the weight W by the pressure sensing. Next, the pressure of the surged bladder layer 110 is increased to fix the surged bladder layer 110 to a higher pressure value, such as a pressure value greater than one (PSI). When the plenum layer 110 is at a fixed pressure value, the pressure sensing layer 130 of the pressure sensing airbag module 100 measures the pressure value of each point, as shown in the output of FIG. 14 to accumulate the points. The pressure value is the sum of the pressures.
之後，經由圖13的控制模組14控制穩壓氣囊層110釋壓，並在釋壓過程中相隔每一間隔參數進行量測。在本實施例中，承重感測方法量測的參數為穩壓氣囊層110的釋壓值，而間隔參數為穩壓氣囊層110進行釋壓的一間隔壓力。本實施例的氣墊裝置10相隔每一間隔壓力即進行一次量測，例如是穩壓氣囊層110每釋壓0.3(PSI)即以壓力感測層130量測當時的壓力總和。上述的間隔壓力不限定於0.3(PSI)，此處僅是用以舉例說明，而間隔壓力的數值愈小，所得的曲線也越準確。如此反覆量測每間隔壓力的壓力總和，便可以得到在承受固定重量W的情況下，壓力感測層130所量測的壓力總和對應於穩壓氣囊層110的壓力的曲線圖，如圖15所示。 Thereafter, the pressure-regulating airbag layer 110 is controlled to be depressurized via the control module 14 of FIG. 13, and is measured at intervals of each interval during the pressure release process. In the present embodiment, the parameter measured by the load-bearing sensing method is the pressure release value of the surged airbag layer 110, and the interval parameter is an interval pressure at which the pressure-regulating airbag layer 110 performs pressure relief. The air cushion device 10 of the present embodiment performs a measurement at intervals of each interval pressure, for example, the pressure of the pressure-regulating airbag layer 110 is 0.1 (PSI), that is, the pressure sensing layer 130 measures the sum of the pressures at that time. The above-mentioned interval pressure is not limited to 0.3 (PSI), and is merely exemplified here, and the smaller the value of the interval pressure, the more accurate the obtained curve is. By continuously measuring the sum of the pressures of the respective intervals, the graph of the sum of the pressures measured by the pressure sensing layer 130 corresponding to the pressure of the surged airbag layer 110 under the condition of receiving the fixed weight W can be obtained, as shown in FIG. Shown.
圖16繪示圖15的壓力感測結果的曲線圖。請參考圖14至圖16，其中圖16繪示壓力感測器囊模組100在承受不同重量的情況下，穩壓氣囊層110的壓力對應於壓力感測層130所量測的壓力總和的多條曲線。因此，圖16可視為是預先利用壓力感測器囊模組100在承受不同重量的情況下，經由上述量測方法量測壓力總和而計算重量所構成的資料庫。從圖16的多條曲線可以看出壓力感測器囊模組100在承受不同重量的情況下，穩壓氣囊層110的壓力以及壓力感測層130在穩壓氣囊層110釋壓過程中所量測的壓力總和的曲線不同。因此，將圖15所量測的曲線對應於圖16的資料庫(圖15的曲線以虛線繪示)，可以經由圖16的資料庫推估圖15的曲線所對應的重量W。舉例而言，經由上述的量測方法所得的曲線落在圖16的資料庫的兩條曲線之間，而兩條曲線分別代表壓力感測氣囊模組100在承受重量為15公斤的情況下以及承受重量為25公斤的情況下的曲線，故可推估重量W約為20公斤。 FIG. 16 is a graph showing the pressure sensing result of FIG. 15. Please refer to FIG. 14 to FIG. 16 , wherein FIG. 16 illustrates that the pressure of the pressure-regulating airbag layer 110 corresponds to the sum of the pressures measured by the pressure sensing layer 130 when the pressure sensor capsule module 100 is subjected to different weights. Multiple curves. Therefore, FIG. 16 can be regarded as a database formed by pre-measuring the weight of the pressure sensor capsule module 100 under different weights by measuring the sum of the pressures by the above-mentioned measuring method. It can be seen from the plurality of curves of FIG. 16 that the pressure sensor capsule module 100 is subjected to different weights, and the pressure of the surged airbag layer 110 and the pressure sensing layer 130 are in the process of releasing the pressure-regulating airbag layer 110. The measured sum of the pressures is different. Therefore, the curve measured in FIG. 15 corresponds to the database of FIG. 16 (the curve of FIG. 15 is shown by a broken line), and the weight W corresponding to the curve of FIG. 15 can be estimated via the database of FIG. For example, the curve obtained by the above measurement method falls between the two curves of the database of FIG. 16, and the two curves respectively represent that the pressure sensing airbag module 100 is under the weight of 15 kg and With a curve of 25 kg, it can be estimated that the weight W is about 20 kg.
圖17繪示圖14的壓力感測氣囊模組的另一承重感測流程圖。同樣地，在本實施例中，圖14的壓力感測氣囊模組100的壓力感測示意圖亦可藉由圖17的承重感測流程量測重量，其中圖15的承重感測流程的參數為穩壓氣囊層110釋壓的間隔壓力，而圖17的承重感測流程的參數為穩壓氣囊層110的釋壓時間。因此，圖17的承重感測流程是以每一間隔時間作為進行量測的依據。請參考圖14與圖17，在本實施例中，以經由氣墊裝置10感測承重的承重感測方法包括下列步驟。首先，藉由壓力感測氣囊 模組100承受重量W。接著，增加穩壓氣囊層110的壓力並固定於較高的壓力值，例如是壓力值大於1(PSI)，並且藉由壓力感測氣囊模組100經由壓力感測層130量測壓力值，以經由累加壓力值而得到壓力總和。 FIG. 17 is a flow chart showing another load sensing of the pressure sensing airbag module of FIG. 14. Similarly, in the present embodiment, the pressure sensing schematic diagram of the pressure sensing airbag module 100 of FIG. 14 can also measure the weight by the load sensing sensing process of FIG. 17, wherein the parameters of the load sensing process of FIG. 15 are The interval pressure of the pressure-regulating airbag layer 110 is released, and the parameter of the load-bearing sensing flow of FIG. 17 is the pressure-relieving time of the surged airbag layer 110. Therefore, the load-bearing sensing process of FIG. 17 is based on each interval time as a basis for measurement. Referring to FIG. 14 and FIG. 17, in the present embodiment, the load-bearing sensing method for sensing the load bearing via the air cushion device 10 includes the following steps. First, by pressure sensing the airbag The module 100 is subjected to a weight W. Next, the pressure of the plenum bladder layer 110 is increased and fixed to a higher pressure value, such as a pressure value greater than 1 (PSI), and the pressure sensing airbag module 100 is used to measure the pressure value via the pressure sensing layer 130. The sum of the pressures is obtained by accumulating the pressure values.
之後，經由圖13的控制模組14控制穩壓氣囊層110釋壓，並在釋壓過程中相隔每一間隔參數進行量測，其中本實施例的參數為穩壓氣囊層110的釋壓時間，而間隔參數為穩壓氣囊層110進行釋壓的一間隔時間。因此，本實施例的氣墊裝置10相隔每一間隔時間即進行一次量測，例如是穩壓氣囊層110每釋壓1秒即量測當時的壓力總和。上述的間隔時間不限定於1秒，而間隔時間的數值愈小，所得的曲線也越準確。如此反覆量測每間隔時間的壓力總和，便可以得到在承受固定重量W的情況下，壓力感測層130所量測的壓力總和對應於穩壓氣囊層110的釋壓時間的曲線圖，如圖17所示。 Thereafter, the pressure-regulating airbag layer 110 is controlled to be depressurized via the control module 14 of FIG. 13 and measured at intervals of each interval during the pressure-relief process, wherein the parameter of the embodiment is the pressure-relief time of the surged airbag layer 110. And the interval parameter is an interval time during which the pressure-regulating airbag layer 110 is decompressed. Therefore, the air cushion device 10 of the present embodiment performs the measurement at intervals of each interval, for example, the pressure-pressure airbag layer 110 measures the sum of the pressures every time the pressure is released for one second. The above interval time is not limited to 1 second, and the smaller the interval time value, the more accurate the obtained curve is. By continuously measuring the sum of the pressures per interval time, a graph of the sum of the pressures measured by the pressure sensing layer 130 corresponding to the pressure release time of the surged airbag layer 110 can be obtained, for example, in the case of receiving a fixed weight W, such as Figure 17 shows.
圖18繪示圖17的壓力感測結果的曲線圖。請參考圖14、圖17與圖18，其中圖18繪示壓力感測器囊模組100在承受不同重量的情況下，穩壓氣囊層110的釋壓時間對應於壓力感測層130所量測的壓力總和的多條曲線。因此，圖18可視為是預先利用壓力感測器囊模組100在承受不同重量的情況下，經由上述量測方法量測壓力總和而計算重量所構成的資料庫。從圖18的多條曲線可以看出壓力感測器囊模組100在承受不同重量的情況下，穩壓氣囊層110的釋壓時間以及壓力感測層130在穩壓氣囊層110釋 壓過程中所量測的壓力總和的曲線不同。因此，將圖17所量測的曲線對應於圖18的資料庫(圖17的曲線以虛線繪示)，可以經由圖18的資料庫推估圖17的曲線所對應的重量W。舉例而言，經由上述的量測方法所得的曲線落在圖16中代表10公斤與15公斤的曲線之間，故可推估重量W約為12公斤。據此，壓力感測氣囊模組100可以藉由上述的兩種量測方法量測其所承受的重量。 FIG. 18 is a graph showing the pressure sensing result of FIG. 17. Please refer to FIG. 14 , FIG. 17 and FIG. 18 , wherein FIG. 18 illustrates that the pressure sensor capsule 100 has a pressure release time corresponding to the pressure sensing layer 130 when the pressure sensor capsule module 100 is subjected to different weights. Multiple curves of the sum of the measured pressures. Therefore, FIG. 18 can be regarded as a database formed by pre-measuring the weight of the pressure sensor capsule module 100 under different weights by measuring the sum of the pressures by the above-mentioned measuring method. It can be seen from the plurality of curves of FIG. 18 that the pressure sensor capsule module 100 is subjected to different weights, the pressure release time of the surged airbag layer 110 and the pressure sensing layer 130 are released in the pressure-regulating airbag layer 110. The curve of the sum of the pressures measured during the press is different. Therefore, the curve measured in FIG. 17 corresponds to the database of FIG. 18 (the curve of FIG. 17 is shown by a broken line), and the weight W corresponding to the curve of FIG. 17 can be estimated via the database of FIG. For example, the curve obtained by the above-described measurement method falls between the curves of 10 kg and 15 kg in Fig. 16, so that the weight W can be estimated to be about 12 kg. Accordingly, the pressure sensing airbag module 100 can measure the weight it bears by the above two measurement methods.
