[0040] In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present application. Specifically, the described embodiments are only some of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0042] The present application will be further described in detail below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than to limit the invention. In addition, it should be noted that only the parts related to the invention are shown in the drawings for the convenience of description.

[0043] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0044] The present invention provides an occupant classification and massage system and a vehicle seat. Among them, the occupant classification and massage system is installed in the vehicle seat. The occupant classification and massage system has both an occupant classification function and a massage function. The occupant classification and massage system can not only perform occupant classification alone, but also massage the occupant alone. After classifying the occupant, it can also start the corresponding massage program according to the level of the occupant.

[0045] More importantly, the occupant grading and massage system provided by the present invention can also perform pre-preparation before detecting the occupants. Specifically, by placing gas for occupant detection in the first accommodating chamber, the first accommodating chamber in the massage component has gas at a predetermined pressure, thereby preparing in advance for occupant detection.

[0046] With the occupant classification and massage system provided by the present invention, there is no need to start the detection and massage work after the occupant comes into contact with the system. If the corresponding program is started after the occupant sits on the vehicle seat or comes into contact with the occupant classification system, it will cause a lot of waiting time for the occupant. The existing product technology uses this waiting time to do corresponding preparation work, such as starting the air source system to supply air, signal processing and transmission, etc. These preparation works will reduce the work efficiency of the product and bring a poor experience to the passengers.

[0047] The occupant grading and massage system of the present invention is already prepared even after the occupant leaves the occupant grading and massage system or before the occupant comes into contact with the occupant grading and massage system. Gas for occupant detection is placed in the first accommodating chamber of the massage component. When the occupant applies pressure to the massage component, the air pressure in the first accommodating chamber will change, and the air pressure detection component will transmit the detected air pressure to the electronic control unit, so as to grade the occupant and start the corresponding massage program.

[0048] Therefore, the occupant classification and massage system provided by the present invention can provide a more comfortable environment for the occupants with higher efficiency, which is in line with the development trend of intelligence and humanization.

[0049] Figure 1 is a schematic structural diagram of a vehicle seat of the present invention, wherein the first accommodating cavity 111 and the second accommodating cavity 113 of the massage assembly 110 in the vehicle seat 200 are in an initial state; Figure 2 is a schematic structural diagram of a vehicle seat of the present invention, wherein the first accommodating cavity 111 and the second accommodating cavity 113 of the massage assembly 110 in the vehicle seat 200 are in a detection state; Figure 3 2 is a schematic diagram of the structure of a vehicle seat of the present invention, wherein the first accommodating cavity 111 and the second accommodating cavity 113 of the massage component 110 in the vehicle seat 200 are in a massage state. Figure 1 , Figure 2 and Figure 3 , respectively give different usage status diagrams of occupant classification and massage system 100.

[0050] Figure 1The state diagram in the initial state is shown. The occupant is not seated on the vehicle seat 200. At this time, the first accommodation cavity 111 of the massage component 110 contains gas for occupant detection. It can be understood that there is sufficient air pressure in the first accommodation cavity 111 so that when the occupant is seated in the seating area 210 or the backrest area, the air pressure detection component 130 can detect the pressure value or pressure change in the first accommodation cavity 111 and transmit the pressure or pressure change to the first control unit.

[0051] It can be seen from Figure 2 that after the first accommodation cavity 111 and the second accommodation cavity 113 of the massage component 110 of the occupant grading and massage system 100 are pressurized, they are in a flattened state. At this time, at least the air pressure in the first accommodation cavity 111 changes correspondingly compared with the initial value. The electronic control unit 140 grades the occupant according to the air pressure value detected by the air pressure detection component 130 or the air pressure change between the detected air pressure value and the initial value.

[0052] Figure 3 It shows that the second accommodation cavity 113 in the massage component 110 is in an expanded state and starts to massage the occupant. In this mode, the electronic control unit 140 starts the corresponding massage program according to the level of the occupant and massages the occupant. Specifically, according to the air pressure value and the rate of change of the air pressure in the second accommodation cavity 113, the massage layer 115 can massage the occupant with different intensities.

[0053] It can be seen from Figure 1 , Figure 2 and Figure 3 that the vehicle seat 200 is divided into a seating area 210 and a backrest area 220. The massage component 110 in the occupant grading and massage system 100 can be separately arranged in the seating area 210, or can be separately arranged in the backrest area, or the massage component 110 can be arranged in both the seating area 210 and the backrest area 220 at the same time.

[0054] It can also be seen from Figure 1 , Figure 2 and Figure 3 that in the seating area 210 or the backrest area 220, a comfort layer 117 and a leather cover layer 116 are also arranged above the massage component 110 to make the surface of the vehicle seat 200 more comfortable and beautiful; a foam layer 118 is also arranged below the massage component 110. The foam layer 118 can support the entire massage component 110 and can also adjust the basic softness of the seat.

[0055] Figure 6 This is a schematic connection diagram of an occupant grading and massage system according to the present invention. Figure 7 This is another schematic connection diagram of an occupant grading and massage system according to the present invention. CombiningFigure 6 and Figure 7 The occupant classification detection and massage system provided by the present invention includes a massage component 110, a gas source 120, a pressure detection component 130, and an electronic control unit 140.

[0056] Among them, the massage component 110 is provided with a first accommodation cavity 111 and a second accommodation cavity 113. The first accommodation cavity 111 and the second accommodation cavity 113 are adjacent. At least part of the outer surface forming the second accommodation cavity 113 is a massage layer 115, and the pressure borne on the massage layer 115 can be transmitted to the first accommodation cavity 111. A gas for occupant detection is disposed in the first accommodation cavity 111.

[0057] The gas supply end of the gas source 120 is connected to the massage component 110 to supply gas for occupant detection and massage to the first accommodation cavity 111 and / or the second accommodation cavity 113.

[0058] The detection end of the pressure detection component 130 is connected to the massage component 110, and can at least detect the pressure in the first accommodation cavity 111.

[0059] The electronic control unit 140 is connected to the pressure detection component 130 to obtain the detected air pressure in the first accommodation cavity 111. The electronic control unit 140 is also connected to the gas source 120, and controls the gas source 120 to supply gas for occupant detection and massage to the first accommodation cavity 111 and the second accommodation cavity 113 according to the detected air pressure.

[0060] For the occupant classification and massage system 100 provided by the present invention, when an occupant sits on the vehicle seat 200 and presses the massage layer 115 of the second accommodation cavity 113 of the massage component 110, the pressure exerted by the occupant will be transmitted to the first accommodation cavity 111 through the second accommodation cavity 113, thereby causing a pressure change in the first accommodation cavity 111. The pressure detection component 130 connected to the massage component 110 can detect the pressure in the first accommodation cavity 111 and transmit it to the electronic control unit 140. The electronic control unit 140 can classify the occupant according to the obtained detected pressure, and according to the level of the occupant, control the gas source 120 to supply gas for occupant massage to the second accommodation cavity 113, start the massage program, and massage the occupant of this level.

[0061] Since a gas for occupant detection is stored in the first accommodation cavity 111 of the massage component 110, before the occupant sits on the vehicle seat 200, the detection and classification of the occupant are fully prepared, so that the detection and classification program of the occupant can be started simultaneously when the occupant sits on the vehicle seat 200, and then control and adjust the vehicle seat 200 to prepare a massage program matching the occupant of this level, improving the comfort of different occupants.

[0062] After the massage component determines the level of the occupant, the electronic control unit can control the inflation and deflation of the massage component to achieve the massage function of the seat. The electronic control unit controls the inflation and deflation of the massage components in the areas where the occupant's body can contact the seat, massaging the occupant, while the massage components in the areas of the seat not touched by the occupant's body remain in the initial state without inflation and deflation, which can save the air source and energy.

[0063] After the electronic control unit controls the second accommodation cavity of the massage component to be filled with gas, quickly release part of the gas in the airbag, and then quickly control the airbag to be filled with gas. As a deflation and inflation cycle, by quickly charging and discharging part of the gas in the detection airbag multiple times, some areas of the massage airbag are lifted multiple times per unit time, generating a knocking massage feeling on the occupant's massage area, relaxing the muscles of the occupant's knocking massage part and making it more comfortable.

[0064] In an embodiment of the present invention, combined with Figures 1 to 5 , the occupant classification and massage system 100 further includes an elastic element 150. The elastic element 150 is arranged in the first accommodation cavity 111 and can provide elastic force to the inner wall when the first accommodation cavity 111 is flattened, so as to support the first accommodation cavity 111 to return to the initial state.

[0065] By arranging the elastic element 150 in the first accommodation cavity 111, when the first accommodation cavity 111 is compressed, the elastic element 150 applies a restoring elastic force to the inner wall of the first accommodation cavity 111, which is beneficial to the first accommodation cavity 111 to return to the initial state, so that the first accommodation cavity 111 can be filled with gas for occupant detection.

[0066] Timely reserve gas for occupant detection in the first accommodation cavity 111. When the occupant sits on the vehicle seat 200, the occupant can be detected and classified in time, which can save more time for the occupant and provide a more comfortable riding environment for the occupant in time.

[0067] In an embodiment of the present invention, the elastic element 150 includes a flexible rebound member 151. The flexible rebound member 151 is provided with a plurality of air holes or a plurality of air channels, and the plurality of air holes and the plurality of air channels are used to accommodate gas.

[0068] The air holes or air channels in the flexible rebound member 151 can play a role in storing gas for occupant detection, so that the first accommodation cavity 111 can be filled with more gas for occupant detection in a shorter time, improving the gas storage capacity in the first accommodation cavity 111.

[0069] In an embodiment of the present invention, combined with Figures 1 to 5 , and Figures 9 to 11, the massage component 110 includes a plurality of second accommodation cavities 113. The plurality of second accommodation cavities 113 and the first accommodation cavity 111 are arranged in sequence along the first direction A, and the first direction A is the force-receiving direction of the massage layer 115.

[0070] The stacked arrangement of the plurality of second accommodation cavities 113 and the first accommodation cavity 111 is beneficial to transmitting the pressure exerted by the occupant on the massage layer 115 to the first accommodation cavity 111, and is also beneficial to the cooperation of the plurality of accommodation cavities to initiate different massage modes for the occupant.

[0071] In an embodiment of the present invention, both the first accommodation cavity 111 and the second accommodation cavity 113 are made of a thin film material 160.

[0072] The first accommodation cavity 111 and the second accommodation cavity 113 made of a thin film, such as air bags, are arranged in the occupant classification and massage system 100, which is not only convenient for processing and forming, but also can set air bags of different volumes according to the space size.

[0073] Figure 12 For the strokes after the first accommodation cavity 111 and the second accommodation cavity 113 in the massage component 110 of the occupant classification and massage system of the present invention are inflated, the first accommodation cavity 111 has a first stroke B, and the second accommodation cavity 113 has a second stroke C. Combining Figure 12 , in an embodiment of the present invention, both the first accommodation cavity 111 and the second accommodation cavity 113 have an inflated state and a deflated state. When the first accommodation cavity 111 changes from the deflated state to the inflated state, the first accommodation cavity 111 has a first stroke B along the first direction A; when the second accommodation cavity 113 changes from the deflated state to the inflated state, the second accommodation cavity 113 has a second stroke C along the first direction A, where the first stroke B is greater than the second stroke C.

[0074] Since the first stroke B generated when the first accommodation cavity 111 is in the inflated state is relatively large, after the massage program is started, the second accommodation cavity 113 can apply a force to the occupant with a relatively small round-trip stroke, which is beneficial to adjusting different massage modes applied by the massage component 110 to the occupant.

[0075] In an implementation manner of the occupant classification and massage system 100 of the present invention, two adjacent second accommodation cavities 113 are either connected or isolated from each other. The plurality of second accommodation cavities 113 cooperate with each other to form a variety of massage modes, improving the applicable range of the occupant classification and massage system 100 and meeting the diverse needs of different occupants.

Among them, the first accommodation cavity 111 and the second accommodation cavity 113 share a ventilation port.

[0077] In an embodiment of the occupant classification and massage system 100 of the present invention, the first accommodation cavity 111 and the second accommodation cavity 113 are connected or isolated from each other.

[0078] When the first accommodation cavity 111 and the second accommodation cavity 113 are connected, they can share a gas supply port. The gas source 120 supplies gas to the first accommodation cavity 111 and the second accommodation cavity 113 simultaneously through one gas supply port. The gas should be stable and can be used for occupant detection and massage.

[0079] When the first accommodation cavity 111 and the second accommodation cavity 113 are isolated from each other, one gas supply port connected to the first accommodation cavity 111 and another gas supply port connected to the second accommodation cavity 113 can be respectively provided. Such an arrangement can independently control the detection and classification of the occupant and the massage of the occupant according to different programs.
