Support the overall shape, the skeleton part is located in the seat part 1, and the part is located in the backrest part 2, the skeleton can be a solid wood skeleton, or a metal skeleton such as an aluminum profile skeleton, a steel skeleton, etc.; the inside of the seat part 1 and the backrest part 2 are filled with Fillers such as flocculent fillers or sponge particles are used to fill the seat 1 and backrest 2 of the sofa body fully, and armrests 3 can also be installed at both ends of the sofa in the width direction. The above-mentioned structures and settings all belong to the conventional design, which will not be repeated here.

The inside of the seat 1 is arranged with multiple sets of massage components along the width direction of the seat 1. In this application, the width direction of the seat 1 is the width direction of the sofa. That is, the direction from one handrail 3 to another handrail 3 .

A set of massage components includes a plurality of massage sub-units arranged along the length direction of the seat 1. In this application, the length direction of the seat 1 refers to the direction from close to the backrest 2 towards the direction away from the backrest 2. For example, When the user is sitting on the sofa, the length direction of the user's thigh is the length direction of the seat part 1 .

Referring to Fig. 2, each massage assembly has a unique first number, for example, based on the width direction of the seat 1, the first number of each massage assembly is W1, W2, W3, W4, W5, W6, .... A massage sub-unit includes airbags, inflation and deflation devices, and pressure sensors; among them, multiple groups of massage components are filled with flocculent fillers, and the skin material of the airbags can be made of rubber, or natural rubber combined into a strong aramid fiber composite material Such as high-strength materials, the inflation and deflation device is connected to the air bag to inflate and deflate the air bag. Specifically, the air bag and the inflation and deflation device can be communicated through a connecting pipe. In one embodiment, the upper surface of the skeleton is installed with The bearing layer, the bearing layer can be set as a sponge layer or other material layers with a certain degree of elasticity, and the connection relationship between the airbag and the bearing layer can be in the form of bonding to realize the fixed connection of part of the skin of the airbag to the surface of the bearing layer.

The pressure sensor is installed on the top of the airbag. When the user sits on the sofa, the pressure sensor on the top of the airbag can directly detect the pressure exerted by the user, and when the airbag is inflated, the pressure sensor can act as a bump to the user. Carry out targeted pressure massage on the corresponding position of the leg to improve the massage effect; wherein, each massage subunit has a unique second number, for example, the second number of each massage subunit of the massage component whose first number is W2 The order is W2L1, W2L2, W2L3, W2L4, W2L5, W2L6, .... The air bag, inflation and deflation device, and pressure sensor in each massage subunit are all associated with the second number of the massage subunit; in one embodiment, the second number of a plurality of massage subunits in the massage assembly is close The backrest 2 grows gradually away from the backrest 2; the massage subunits in the same group of massage components are divided into two parts, the side close to the backrest 2 is the proximal part, and the side far away from the backrest 2 is the far part; for example, When the massage assembly with the first number W2 contains 8 massage sub-units, the second number of the 8 massage sub-units gradually increases from near the backrest 2 to away from the backrest 2 and is W2L1, W2L2, W2L3, W2L4, W2L5, W2L6, W2L7, W2L8, then W2L1, W2L2, W2L3, W2L4 are the second numbers of the near part, W2L5, W2L6, W2L7, W2L8 are the second numbers of the far part.

When the pressure sensor senses a pressure value exceeding a preset threshold, the pressure value is sent to the processing module, and carries a second number associated with the pressure sensor;

With reference to Figure 3, the multi-functional upholstered sofa also includes a processing module, the inflation and deflation device and the pressure sensor are all in communication with the processing module, specifically, it is preferable to use wireless communication, such as LoRa technology, [WiFi/IEEE 802.11] protocol, [ ZigBee/802.15.4] protocol, [Thread /IEEE 802.15.4], [Z-Wave] protocol, etc. to achieve communication, the processing module includes a receiving unit, a screening unit, an analysis unit, a matching unit and a control unit;

Wherein, the receiving unit is used to receive pressure values from multiple pressure sensors. It can be understood that, when receiving pressure values from multiple pressure sensors, the second number carried by each pressure sensor is also received, and the second number is the same as The associated pressure value is sent as a data packet to the receiving unit;

The screening unit is used to screen out several groups of massaging components to be worked on according to the carried second numbers and combine them as working groups;

Specifically, following the above example, the first number of the massage components to which it belongs can be obtained from the second number carried by the pressure value, and then these massage components can be screened out as massage components to be worked, and these massage components to be worked Massage components are combined into a set of workgroups.

The analysis unit is used to analyze and obtain the peak inflation volume of each airbag in the working group according to the multiple pressure values and the carried second number;

Specifically, including:

Obtaining a plurality of carried second numbers as a first average of pressure values associated with proximal massage subunits, and a plurality of carried second numbers as a second average of pressure values associated with distal massage subunits value;

In the case that the first average value is not greater than the second average value, the preset inflation amount is used as the second number carried by the number to be the peak value of the inflation amount of the airbag in the massage subunit of the far part, and two-thirds The preset inflation amount as a plurality of carried second numbers is the peak inflation amount of the airbag in the massage subunit associated with the proximal part;

In the case that the first average value is greater than the second average value, the preset inflation amount is taken as the peak value of the inflation amount of the airbag in the remote massage sub-unit, and the preset inflation amount is taken as The second number carried by the plurality is associated with the peak value of the inflation amount of the air bag in the massage subunit at the proximal part.

For example, if the second numbers carried by multiple numbers are W1L3, W1L4, W1L5, W1L6, W1L7, W1L8, W2L2, W2L3, W2L4, W2L5, W2L6, W2L7, W3L3, W3L4, W3L5, W3L6, W3L7, W3L8, then calculate W1L3, W3L6, W3L7, W3L8 The average value of the pressure values attached to W1L4, W2L2, W2L3, W2L4, W3L3, W3L4 is used as the first average value to calculate the The average value of the pressure value is used as the second average value; then compare the size of the first average value and the second average value, and when the first average value is not greater than the second average value, the preset inflation amount is used as the The second number is associated with the peak inflation volume of the airbag in the massage subunit of the far part, and the second number is associated with the airbag in the massage subunit of the near part, taking two-thirds of the preset inflation volume as a plurality of carrying The peak value of the inflation volume, wherein the preset inflation volume is a preset value, which can be set according to the actual massage force.

In the case that the first average value is greater than the second average value, the preset inflation amount is taken as the peak value of the inflation amount of the airbag in the remote massage sub-unit, and the preset inflation amount is taken as The second number carried by the plurality is associated with the peak value of the inflation amount of the air bag in the massage subunit at the proximal part.

According to the pressure values of the near part and the far part, it reflects the user's sitting posture angle, that is, the inclination angle of the user's legs on the sofa, for example, when the first average value of the near part is smaller than the second average value of the far part, It shows that the area of the sofa seat part 1 corresponding to the user's sitting position is higher on the side close to the backrest part 2 than on the side away from the backrest part 2. At this time, the peak value of the inflation amount of the airbag at the far part in the working group is high. If the peak value of the near part is inflated, it is difficult for the user to slide down toward the side away from the backrest 2 during the massage process; when the first average value of the near part is higher than the second average value of the far part, it means that the user is using If the area of the sofa seat part 1 corresponding to the sitting position of the person is relatively sunken on the side close to the backrest part 2 relative to the side away from the backrest part 2, the above factors need not be considered. If the peak value of air volume is equal to the peak value of inflation volume in the near part, then during the massage process, the user can enjoy the massage with the same strength everywhere on the legs located on the sofa.

The matching unit is used to generate action timing according to the working group and pressure value, and the action timing includes the order and duration of inflation of each airbag in the working group;

Specifically, including:

According to the working group and the pressure value, the action timing is obtained by matching in the preset data table, and the action timing includes the order and duration of inflation of each airbag in the working group.

The preset data table is a pre-set table for querying action timing. That is, the action sequence is used as the value in the key-value pair, and is pre-recorded through the table. Later, you only need to use the key in the key-value pair to find the corresponding action sequence, instead of generating the action sequence through calculation every time. . It greatly saves computing resources and improves the generation efficiency of action sequences;

In one embodiment, the pre-recorded relationship in the preset data table is the correspondence between the working group, the pressure value and the action sequence. In this case, the working group and pressure value are the keys in the key-value pair, and the action sequence is the value in the key-value pair. The preset data table records each preset working group, the different combinations of multiple second numbers in the working group, and the preset pressure range corresponding to each second number in different combinations, and the correspondence between the action sequence, for example , the default working group is (W1, W2, W3), one of the different combinations of multiple second numbers is (W1L3, W1L4, W1L5, W1L6, W1L7, W1L8, W2L2, W2L3, W2L4, W2L5, W2L6 , W2L7, W3L3, W3L4, W3L5, W3L6, W3L7, W3L8), the preset pressure range corresponding to each second number in this combination is preset, and the action sequence is also preset, for example, in one action cycle, The time node (equivalent to the sequence) when the airbag associated with each second number is inflated, and the duration of the inflation. These action timings are pre-imported and associated to provide different massage modes to adapt to different human sitting postures.

The control unit is used to periodically control each inflation and deflation device in the working group to inflate and deflate the corresponding airbag according to the action sequence and the peak inflation volume of each airbag; specifically, the control unit sequentially inflates and deflates the corresponding airbag according to the corresponding sequence The peak value and duration are sent to the inflation and deflation device associated with the second number; the inflation and deflation device inflates the corresponding airbag according to the peak value and duration of the inflation amount; The airbag is restored to its original state, and the original state of the airbag is still approximately circular, that is, when the airbag is in its original state, there is still a certain amount of air in the airbag.

In one embodiment, the processing module further includes a voice broadcast unit, which is used to send out a voice alarm signal when the pressure value exceeds a preset threshold. If the weight of the sofa is too heavy, which may affect the massage action or the massage components are damaged, an alarm will be issued in time, or when many users are fighting, the pressure value of some parts of the sofa will exceed the standard, and the massage action will not be performed at this time.
