Through the built-in computer integrated board and air bag components of the seat, a series of precisely designed air bag circulation actions are performed to relieve the tense muscles caused by long-term riding, quickly achieve the effect of blood circulation, and effectively relieve fatigue.

[0003] The prior art discloses a leak-proof TPU airbag and a preparation method thereof, wherein the airbag preparation method first punches the surface material and the bottom material to obtain an upper airbag having a first airbag cavity and a lower airbag having a second airbag cavity, respectively, and then the upper airbag and the lower airbag are attached and pre-sealed to form an airbag embryo, wherein the first airbag cavity is connected to the corresponding second airbag cavity to form an airbag monomer, and the airbag embryo is preset with at least one air inlet channel, and then the airbag embryo is inflated and then secondary molding is performed to separate the air inlet channel and the airbag channel to obtain the airbag, and each airbag monomer of the airbag is independent of each other. Since the airbag is an integrated structure, if one of the airbag monomers of the airbag is damaged, the entire airbag needs to be replaced together, which has high replacement costs and wastes resources.

Finally, the air bladder embryo is heat-sealed for a second time to obtain a massage air bladder inflation and deflation air cushion.

9. A method for preparing a massage airbag inflation and deflation cushion for a new energy vehicle seat according to claim 8, characterized in that: Step S1 includes the following steps: S101, installing the upper core at the bottom of the front mold, the core injection hole of the upper core is connected to the injection hole of the front mold, installing the lower core on the top of the rear mold, installing the ejector mold in the middle of the lower core, connecting the ejector mold to the rear mold, and the upper core, the lower core and the ejector mold form an injection mold; S102, installing the injection molding device of step S101 on the injection molding machine, the injection molding machine presses the injection molding device, so that the upper core, the lower core and the ejector mold are closed to form an injection cavity, and the injection molding machine injects liquefied TPU from the injection hole of the front mold, and the liquefied TPU flows into the injection cavity through the core injection hole until the injection cavity is filled with TPU; S103, a constant temperature coolant enters and exits the injection molding device through the coolant inlet and outlet holes, and the constant temperature coolant cools the injection molding device until the liquefied TPU is completely solidified and cooled to a room temperature state, thereby obtaining a capsular sheet; S104, the injection molding machine drives the front mold and the rear mold to separate, and under the action of the spring of the rear mold, the upper core and the lower core are separated, and at the same time, the ejector pin of the rear mold pushes the ejector mold to move upward, thereby ejecting the capsule from the lower core.

10. A method for preparing a massage airbag inflation and deflation cushion for a new energy vehicle seat according to claim 9, characterized in that: The temperature range of the liquefied TPU in step S102 includes 180-230°C.
