[0034] Example 1

[0035] The utility model embodiment provides an airbag pressurizing device, referring to Figure 1 , Figure 1 This is a first schematic diagram of the structure of the airbag pressurizing device according to an embodiment of the utility model.

[0036] like Figure 1 An airbag pressurizing device shown includes: an inflation and deflation mechanism 1, an air guide tube assembly 2 and an airbag assembly 3, wherein the inflation and deflation mechanism 1 is connected to the airbag assembly 3 via the air guide tube assembly 2; when the airbag assembly 3 needs to be inflated, the inflation and deflation mechanism 1 is powered on and inflated, and the airflow is supplied to the airbag assembly 3 via the air guide tube assembly 2; when the airbag assembly 3 needs to be deflated, the inflation and deflation mechanism 1 is powered off, and the airflow returns to the inflation and deflation mechanism 1 via the air guide tube assembly 2.

[0037] It should be noted that the specific working state of the inflation and deflation mechanism is controlled by an external control module or power module. In the specific implementation, the control module or power module issues a corresponding inflation command to power on the inflation and deflation mechanism, and the air valve in the inflation and deflation mechanism is converted to a closed state. At the same time, the air pump inflates, and the generated airflow is supplied to the airbag part until the pressure generated by the airbag reaches a preset value, and the air pump cuts off the power and stops inflating; after a period of inflation, the control module or power module issues a corresponding deflation command, and the air valve begins to cut off the power and change to a deflated state. The airflow returns from the airbag through the air guide tube assembly to the inflation and deflation mechanism to achieve deflation.

[0038] refer to Figure 2 , Figure 2 This is the first schematic diagram of the split structure of the inflation and deflation mechanism of the embodiment of the utility model.

The air valve 122 is arranged above the soft glue 121, and the air pump 123 is arranged on one side of the soft glue 121. A three-way structure connected to the air guide tube assembly 2 is formed between the soft glue 121, the air valve 122 and the air pump 123.

[0043] It can be understood that the soft glue structure in this embodiment is a connection structure made of a soft glue material. In specific implementations, it usually refers to a general term for flexible materials. Commonly used materials include: PVC material or TPU material, etc.

[0044] The air guide tube assembly 2 comprises an air bag nozzle 21 and an air bag air tube assembly 22.

[0046] It should be noted that, in this embodiment, there are two ways to connect the inflation and deflation mechanism to each airbag body of the airbag assembly. One is to connect to the airbag body through the airbag air tube and the air guide tube, and the other is to connect to the airbag body only through the airbag air tube.

[0047] refer to Figure 1A , Figure 1AThis is the second schematic diagram of the structure of the airbag pressurizing device provided in Example 1 of the utility model. The first airbag group 31 includes at least one first airbag body 311. The first airbag air tube unit includes first airbag air tubes 221 matching the number of first airbag bodies 311. One end of at least one first airbag air tube 221 is connected to the soft rubber 121 in the air pump air valve assembly 12, and the other end is connected to each first airbag body 311.

[0048] It can be understood that, in a specific implementation, the number of first airbag bodies in the first airbag group can be designed accordingly according to demand.

[0049] The second airbag group 32 includes at least one second airbag body 321, and the second airbag air tube unit includes second airbag air tubes 222 and air guide tubes 223 that match the number of second airbag bodies 321.

[0052] It should also be noted that when the inflation and deflation mechanism and the airbag body of the airbag assembly are connected to the airbag body only through the airbag air pipe, an anti-blocking air strip will be provided inside the connection between the airbag air pipe and the airbag body, which is used to prevent blockage in the connection between the airbag air pipe and the airbag body.

[0053] This embodiment realizes the stable integration of the pump, valve, and airbag in the structural member with a structure that is easy to install and has a small volume. At the same time, it can be fixed together with the fabric of the wearable device to complete the function of cyclic pressurization and pressure relief, which greatly reduces the volume and weight of the pressurization device of the wearable device.

[0060] Step S10: when the airbag pressurizing device is started, the air valve is energized and in a closed state, and the air pump inflates the airbag assembly through the airbag air tube assembly;

[0061] It should be noted that, in a specific implementation, the airbag pressurizing device inflates and deflates each airbag body of the airbag assembly simultaneously, that is, the corresponding pressure change process of each airbag body due to the change of its own air content is generally consistent.

[0062] Step S20: When inflation is completed, the air valve is powered off and in a deflated state, and air is gradually discharged from the airbag assembly.

[0063] It can be understood that "inflation is complete" specifically means that the air content of the airbag reaches a predetermined value or the working state of the airbag pressurizing device changes.
