Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent seat cushions and mattresses, and specifically relates to intelligent seat cushions and mattresses. Background Art

[0002] When people are in a sedentary state, the buttocks of the human body are under pressure for a long time, especially at the bony prominences, where pressure concentration is likely to occur, causing local tissue damage. Currently, most of the seat cushions sold on the market are sponge seat cushions, spring seat cushions, latex seat cushions, and airbag seat cushions. These seat cushions use the elasticity of the material itself to improve the comfort of users. However, they cannot sense the contact force between the seat cushion and the human body, and cannot make the force on the contact part between the human body and the seat cushion uniform and the pressure consistent. To solve this problem, the prior art has begun to introduce seat cushion devices with sensing and adjustment functions. Such seat cushions usually adopt the airbag type and use the inflation / deflation operation of the airbag to achieve the adjustment of the seat cushion. For example, in the Chinese patent "Intelligent Seat Cushion and Seat" (Patent No. 202322958288.0), the intelligent seat cushion includes a functional mechanism and an adjustment mechanism. The functional mechanism includes multiple airbags, and the adjustment mechanism includes a processing module, a pressure adjustment component, and multiple pressure detection components. The pressure adjustment component is used to inflate and deflate the airbag, and the pressure detection component is used to detect the external pressure received by the airbag and transmit the detection information to the processing module. The processing module causes the pressure adjustment component to inflate or deflate the corresponding airbag; when the user adjusts the sitting posture or changes the pressure covering area on the intelligent seat cushion, the pressure detection component can detect the external pressure received by the airbag in real time. The processing module controls the pressure adjustment component to inflate and deflate the airbag according to the pressure change, and adjusts the internal pressure of the airbag accordingly. The supporting force provided by the airbag is adaptively adjusted according to the current pressure, improving the comfort of the intelligent seat cushion. Since the area occupied by the airbag is much larger than the area involved in the ergonomic structure, it can only improve the comfort to a certain extent, and cannot accurately adjust the pressure values received by each part.

[0003] In a similar situation, for people who are bedridden for a long time, the pressure values at the contact parts between the human body and the mattress are uneven, which is also likely to cause local tissue damage and form bedsores. Summary of the Invention

[0004] The purpose of the utility model is to solve the deficiencies of the prior art and provide intelligent seat cushions and mattresses.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] Intelligent seat cushions and mattresses, including electric push rod assemblies, brackets, power supply units, control devices and seat cushion or mattress covers, are characterized in that: the electric push rod assemblies are installed on the brackets in a way that the spacing is equal to the row spacing. The electric push rod assemblies include top plates, push rods, transmission assemblies and pressure sensors. The top plates and the push rods adopt a universal hinge structure, and the top plates are made of elastic materials; the push rods and the transmission assemblies are connected by screws; the transmission assemblies include motors, reducers and screw rods, where the screw rods match the internal threads of the push rods; the screw rods are fixedly connected to the output shafts of the reducers, and the input shafts of the reducers are connected to the output shafts of the motors;

[0007] The pressure sensors are arranged at the ends of the push rods, and the pressure sensors communicate with the control devices in a wired or wireless manner; the power supply unit supplies power to each electric push rod assembly and the control device; the seat cushion or mattress cover covers the array formed by the electric push rod assemblies.

[0008] The specific principle includes: accurately and real-time collecting the pressure indexes of each point through the pressure sensors and transmitting them to the control device; the control device uses a preset algorithm of taking the arithmetic mean of the pressure values of each point to perform real-time dynamic calculations on the data collected from all points, intelligently judge the operation results, and send corresponding instructions to each electric push rod; after receiving the instructions from the control device, the electric push rods adjust the pressure of each point by raising or lowering the height of the push rods until the pressure values of each point tend to be consistent.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The utility model adopts an electric push rod array, places the pressure sensors at the ends of the push rods, can more sensitively and accurately sense and collect the pressure indexes of each point, and transmits them to the controller in real time. The control device uses a preset algorithm of taking the arithmetic mean of the pressure values of each point to perform real-time dynamic calculations on the data collected from all the stressed points, intelligently judge the operation results, and send instructions to raise or lower the height of each stressed electric push rod to adjust the pressure of each point. The pressure adjustment speed is fast and the granularity is high, which can quickly adapt to the sitting or lying posture of the human body and the adjustment of the sitting or lying posture, making the human body more comfortable and healthy when sitting or lying.
