[0025] The embodiments of the utility model are described in detail below.

[0026] As Figures 1-4As shown, the embodiment provides an electric control air bag seat cushion, which is divided into multiple seat areas, and includes a flexible seat cushion outer layer 2, a pressure sensor group 3, an air bag group layer 5, a gas charging and discharging device, a control device 1 and a seat cushion base 8. The seat cushion outer layer 2, the pressure sensor group 3, the air bag group layer 5 and the seat cushion base 8 are sequentially arranged from top to bottom. In the embodiment, at least five seat areas are divided according to the direction of the vehicle body, i.e., front, middle, rear, left and right. By adjusting the inflation of the air bag group corresponding to each seat area, the height of the corresponding seat area can be adjusted to adjust the sitting posture of the user on the seat cushion. In other embodiments, the seat area can be further subdivided as needed to achieve more precise adjustment.

[0027] As shown in Figure 1 and Figure 2 The flexible outer layer is located at the uppermost layer of the seat cushion and can adjust the posture of the seat cushion with the deformation of the air bag. In the embodiment, the seat cushion outer layer 2 serves as an outer cover layer and is made of a material with high strength, wear resistance and certain flexibility, which meets the elasticity requirements of the outer cover layer for repeated inflation and deflation of the air bag.

[0028] The pressure sensor group 3 includes multiple pressure sensors, and the pressure sensor group 3 is directly located below the seat cushion outer layer 2. The pressure sensor group 3 includes multiple high-sensitivity pressure sensors, and the pressure sensing range of the pressure sensor group 3 covers the entire seat area of the seat cushion. Specifically, a plurality of pressure sensors are arranged below each seat area, so that the pressure condition of each seat area can be detected by the pressure sensor group 3. Further, when a user uses the seat cushion, the sitting posture of the user can be determined based on the pressure condition of each seat area.

[0029] The air bag group layer 5 is arranged below the pressure sensor group 3 and includes multiple air bag groups that are not in communication with each other. The inflation degree and inflation and deflation condition of the air bags in the same air bag group are the same. A plurality of air bag groups are arranged below each seat area, so that the support condition of the seat cushion can be adjusted by the air bag group below the corresponding seat area. The air bags in the air bag group are made of high-quality elastic material to ensure their durability and comfort.

[0030] The seat cushion base 8 is located below the air bag group layer 5 and is connected to the vehicle frame to provide support. The seat cushion base 8 is made of hard material, and reinforcing structures such as reinforcing ribs are formed thereon.

[0031] The control device 1, in the embodiment, is an ECU, receives the detection signals of the pressure sensor group 3, and determines the user posture according to the pressure conditions of each region. For example, the control device 1 pre-stores pressure distribution models corresponding to multiple postures, when the user uses the cushion, the pressure sensor collects pressure data in real time and transmits it to the control device 1. The control device 1 analyzes the data to determine the user's current sitting posture and body weight distribution, and compares it with the pre-stored model, according to the comparison result, the control device 1 controls the corresponding air bag through the control circuit to accurately inflate and deflate the air bag. For example, if it is detected that the user's lumbar region has excessive pressure, the control device 1 will instruct the air bag group below the region to deflate appropriately to disperse the pressure; if it is detected that the pressure in the hip region is uneven, the air pressure of the surrounding air bags can be adjusted to ensure the user's comfortable sitting posture.

[0032] In this embodiment, the inflation and deflation device is connected with the air bag group and the control device 1, and inflates and deflates the air bags in the specified air bag group according to the instructions of the control device 1, thereby realizing the accurate inflation and deflation of each air bag group as described above. It should be noted that the inflation and deflation amount of the specified air bag group is accurately controlled by the control device 1 according to the pressure value of the corresponding position. In a specific embodiment, the inflation and deflation device is a gas pump 7, which is controlled by the control device 1 to switch its on-off state.

[0033] The inflation and deflation ports of each air bag group are respectively connected to the control device 1 through electromagnetic valves 6. The electromagnetic valves 6 act as switches and are switched by the control device 1. When the electromagnetic valves 6 are closed, even if the inflation device is turned on, the corresponding air bag group cannot be inflated or deflated.

[0034] Through the above structure, automatic inflation and deflation adjustment control of the air bag group can be realized, and this mode is an automatic mode.

[0035] The cushion base 8 is fixed to the vehicle frame, and the cushion base 8 can form a mounting portion for connecting with the inflation and deflation device and / or the control device 1, and the inflation and deflation device and / or the control device 1 are fixed to the corresponding position on the cushion base 8. This facilitates the integrated setting of the overall cushion. Preferably, the inflation device and the control device 1 are installed at the bottom of the cushion base 8, which can reduce the noise generated by the inflation and deflation device during operation, and facilitate disassembly and maintenance.

[0036] In an optional embodiment, the control device 1 is installed inside the cushion, which can prevent external impact and ensure its stability.

[0037] In another embodiment, a manual adjustment module 9 is also provided, which is connected to the control device 1, and the control device 1 is configured to control the inflation and deflation of the airbag group of the designated seat area according to the signal from the manual adjustment module 9. In a specific embodiment, the manual adjustment module 9 includes an inflation and deflation control switch for controlling whether to inflate or deflate the airbag group, and an airbag inflation amount adjustment switch for controlling the inflation amount of the airbag group. In a specific embodiment, the inflation and deflation control switch and the airbag inflation amount adjustment switch can be provided independently or combined. In a specific embodiment, the manual adjustment module 9 is a button, and in other alternative embodiments, the manual adjustment module 9 is a knob. Through the manual adjustment module 9, the airbag group of the seat area to be adjusted and the inflation degree of the corresponding airbag group can be selected, and the adjustment of the inflation degree can be step adjustment or stepless adjustment. For example, the manual adjustment module 9 includes an adjustment button, through which three position adjustments of the cushion can be achieved, i.e., 0%, 50%, and 100% inflation. Alternatively, the manual adjustment module 9 includes an adjustment knob, through which stepless adjustment of the airbag inflation degree between 0% and 100% can be achieved.

[0038] In one embodiment, the manual adjustment module 9 includes a mode switching switch, and the control device 1 is configured to control the inflation and deflation device based on the signal of the manual adjustment module 9 in the manual control mode, and to control the inflation and deflation device based on the signal of the pressure sensor group 3 in the automatic control mode. In this way, the user can manually adjust the inflation and deflation of the airbag group or automatically adjust the inflation and deflation of the airbag group according to the needs in different scenarios.

[0039] As shown in Figure 4 The manual adjustment module 9 is connected to the ECU, which receives the signal from the manual adjustment module 9 to control the current mode to be manual or automatic. The ECU is connected to the pressure sensor group 3, which detects the pressure from the cushion and transmits the signal to the ECU. The ECU is connected to the inflation and deflation device through the relay 4, and the inflation and deflation device in this embodiment is an air pump. The ECU controls the on-off of the pump by controlling the on-off of the relay 4, thereby controlling whether to inflate or deflate the airbag group. At the same time, the airbag group is also connected to the ECU through the electromagnetic valve 6, and the ECU controls the on-off state of the inflation and deflation port of the airbag group by switching the on-off state of the electromagnetic valve 6. That is, if the electromagnetic valve 6 needs to be inflated, the ECU needs to switch the on-off state of the electromagnetic valve 6 and the on-off state of the relay 4.

[0040] The logic of the inflation and deflation control of the airbag in the manual mode and the control mode is as follows Figure 3The three gear adjustments of the seat cushion in the manual mode are taken as an example, that is, 0%, 50%, 100% of the inflation, the corresponding inflation and deflation instructions are given to the ECU through the manual adjustment module 9, and the ECU sends corresponding instructions to the inflation and deflation device according to the received inflation and deflation instructions. In the automatic mode, the pressure sensor group 3 monitors the pressure of each seat area on the seat cushion, and the ECU judges whether the pressure value of a certain part is too low or too low according to the pressure value, and if so, sends an instruction to the inflation and deflation to adjust the inflation and deflation state of the corresponding air bag until the air bag is in the best position, and if not, it is judged that the current air bag is in the best position and does not need to be adjusted.
