[0039] Some embodiments of the utility model will be described in detail below in combination with the drawings.In the case of no conflict, the features in the following examples can be combined with each other.

[0040] Please refer to Figures 1-3 The utility model discloses a kind of support mat based on user posture change support feature distribution, which is multilayer structure, it includes body 1 and electric control device 2, electric control device 2 is arranged in the inside of body 1.Body 1 includes feature change layer 11 and pressure detection layer 12.Feature change layer 11 includes multiple fluid filling units 112 distributed in body 1, pressure detection layer 12 is used to detect the pressure distribution information that user exerts on support mat, further, pressure detection layer 12 is configured above feature change layer 11.Electric control device 2 is electrically connected with pressure detection layer 12, feature change layer 11 respectively, and electric control device 2 is configured to determine the user support area formed on the body based on the pressure distribution information, and then change its support feature distribution in user support area by controlling the saturation of fluid filling unit 112 in corresponding support area.

[0041] It is important to note that the present patent proposes a support cushion based on changing support feature distribution according to user posture, the core principle of which is to achieve intelligent response and personalized support adjustment of the support cushion to the changes in user posture by integrating advanced pressure detection technology and fluid control technology. In this application, "support position change" refers to the changes in the positions of the parts of the user's body that are in contact with the support cushion and generate pressure when using the support cushion. This change can be caused by various factors, such as the user's movement, posture adjustment, or changes in body weight distribution, etc. Specifically, when the user lies on the support cushion, their back, hips, legs, and other parts will be in contact with the support cushion and form pressure points. With the movement or adjustment of the user's posture, the positions and sizes of these pressure points may change. For example, when the user turns from a supine position to a lateral position, the pressure points of their hips and back will change, while the shoulders and hips in the lateral position may become new pressure points. The pressure detection layer of the support cushion can capture these changes in support position in real time and convert them into electrical signals to transmit to the electric control device. The electric control device adjusts the saturation of the corresponding fluid filling unit in the feature changing layer according to these change information, thereby changing the support feature distribution of the support cushion at these changed positions. In this way, no matter how the user's body moves or adjusts the posture, the support cushion can provide the best support effect.

[0042] It should be noted that the pressure detection layer 12 of the present application is located above the feature changing layer 11, which can detect the pressure distribution information applied by the user on the support pad in real time. The electric control device 2 intelligently determines the change of the support position on the support pad according to the pressure distribution information, and accurately controls the fluid filling unit 112 in the corresponding area, so as to realize the personalized adjustment of the support feature. It should be noted that in the case that the fluid filling unit 112 is small enough, when the user's posture on the support pad changes, the support position and the number of the fluid filling unit 112 occupied by different parts of the user's body will change. In the embodiment, the support feature is the support hardness of the support pad, and in other embodiments, the support feature can also be the support height (thickness) of the support pad. The present application can provide real-time feedback of the pressure distribution information (i.e. the change of the support position on the support pad), quickly respond to the change of the user's posture, and automatically adjust the support feature, so as to provide more suitable and comfortable support according to the change of the posture of different users. The pressure detection layer 12 is used to collect the pressure values in the corresponding area of the user due to the change of the posture during the use of the user, so as to determine the distribution of the fluid filling unit 112 in different areas according to the collected pressure values, so as to adjust the support hardness or the support height or the support thickness in the grid area corresponding to the change of the posture of the user, so that the hardness and thickness distribution of the fluid filling unit in the support pad can better match the human body curve of the user, avoid the state that some parts of the body are in the air during sleep, thereby increasing the comfort of the user and improving the sleep quality of the user. In addition, the present application combines the use of the electric control device 2 and the pressure detection technology, so that the support pad has intelligent adjustment capability, can provide personalized support solution according to individual differences, and improves the user experience.

[0043] In the embodiment, the pressure detection layer 12 is located at the top layer of the body 1 (i.e. the surface layer of the support pad), and the pressure detection layer 12 includes a plurality of pressure sensing units. In order to enable the pressure sensing unit to accurately detect the change of the fluid filling unit occupied by the user on the support pad, in the embodiment, the pressure sensing unit is arranged at the top of the pressure detection layer and is in contact with the human body of the user. In order to better realize the feature adjustment function of the present application, the fluid filling unit 112 is uniformly arranged on the body 1, and the pressure sensing unit is correspondingly arranged with the fluid filling unit 112 in the corresponding area. In addition, in the utility model, the fluid can adopt gas or liquid, when the fluid is gas, the pump body adopts air pump, when the fluid is liquid, the pump body can adopt liquid pump.

[0044] Please refer to Figures 4-7The fluid filling unit 112 has a plurality of partitions 3 uniformly distributed in the fluid filling unit 112, and the plurality of partitions 3 are suitable for separating the inner cavity in the fluid filling unit 112 into a plurality of sub-units, and the sub-units are provided with the support 4 made of porous material. It should be noted that, due to the plurality of partitions in the fluid filling unit in the present application, the top surface of the fluid filling unit is close to a plane, the gap between adjacent fluid filling units is smaller, so that it is more sufficient to fit the human body. In addition, the addition of the pressure pad makes the massage layer press the human body more accurately. Because the pressure of the previous air bag is preset to a certain value, whether it can effectively contact the human body and the size of the massage force cannot be accurately experienced by the general human body. In the present application, the addition of the pressure pad accurately reflects the pressure of the pressure part, so as to flexibly adjust the size of the massage force applied to the human body. The addition of the pressure pad also makes the massage air bag press the human body more accurately.

[0045] The feature changing layer 12 is supported by the electric control device 2 to adjust and change the support hardness or the support height or the support thickness. The fluid filling unit 112 is configured to be adjusted at least between a first hardness, a second hardness and a third hardness. The first hardness is formed by the support 4 only when no fluid is filled. The second hardness is formed by the fluid and the support 4 together after a first set amount of fluid is filled. The third hardness is formed by the fluid only after a second set amount of fluid is filled. Further, the first hardness is smaller than the second hardness, the second hardness is smaller than the third hardness, and the second set amount is greater than the first set amount. It should be noted that, by interposing the partitions 3 in the fluid filling unit 112, the support 4 inside is limited in the cavity formed by the plurality of partitions 3, which can avoid the problem that the support is easily displaced when the sealed bag is filled with fluid. When adjusting the hardness of the seat cushion, the middle of the seat cushion not only does not bulge, but also does not have a gap, which improves the user experience.

[0046] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
