An automatic inflation device comprises a flexible accommodating chamber (100), a housing (200) sleeved outside the flexible accommodating chamber (100), and a vibration mechanism (300). The housing (200) comprises a body (210) and clamping rings (220) disposed at two ends of the body (210). The flexible accommodating chamber (100) is fixed in the housing (200) by means of the clamping rings (220), and a sealed gas storage interlayer (500) is formed between the flexible accommodating chamber (100) and the housing (200). A pressure sensor (510) is disposed in the gas storage interlayer (500). An inflation port (230) is disposed on the housing (200). The automatic inflation device also comprises a controller (600), an inflation device (250), and a gas valve (240). The pressure sensor (510) is connected to the controller (600) and outputs gas pressure information to the controller (600). The controller (600) controls the inflation device (250) to inflate the gas storage interlayer (500) until a gas pressure reaches a preset threshold. Each of two ends of the flexible accommodating chamber (100) is provided with an opening, and an accommodating bag is disposed at the opening of one end in a sleeved manner. The gas pressure in the gas storage interlayer (500) is precisely adjusted by means of the controller (600), the adjustment process is automatic, and accordingly automatic inflation and deflation can be implemented.La présente invention concerne un dispositif de gonflage automatique comprenant une chambre de réception flexible (100), un boîtier (200) manchonné à lextérieur de la chambre de réception flexible (100), et un mécanisme de vibration (300). Le boîtier (200) comprend un corps (210) et des anneaux de serrage (220) disposés aux deux extrémités du corps (210). La chambre de réception flexible (100) est fixée dans le boîtier (200) au moyen des bagues de serrage (220), et une couche intermédiaire de stockage de gaz (500) étanche est formée entre la chambre de réce
