[0021] See also Figures 1-4 , the utility model provides a technical solution:

[0022] In the technical solution, a front trunk sealing structure of an automobile comprises a mounting frame 1, wherein a driving sealing structure is provided at the upper end of the mounting frame 1;

[0023] The driving and sealing structure includes: a connecting frame 2, a ventilation cavity 3, a wrapping layer 4, and an inflatable expansion assembly;

[0024] The connecting frame 2 is located at the upper end of the mounting frame 1, the ventilation cavity 3 is located inside the connecting frame 2, the wrapping layer 4 is sleeved on the upper end of the connecting frame 2, one end of the inflatable expansion assembly is communicated with the upper end of the ventilation cavity 3 inside the connecting frame 2, and the other end is connected to one side wall surface of the connecting frame 2.

[0025] In this technical solution, first, through the mounting card slot 8 at the lower end of the mounting frame 1, the mounting frame 1 is fixed at the rubber strip mounting position of the front trunk. Subsequently, one end of the inflatable expansion assembly is placed inside the front trunk. During daily use, through the wrapping layer 4 at the upper end of the connecting frame 2, the daily sealing requirement of the front trunk can be met. In rainy weather, the wrapping layer 4 can be expanded by the cooperation of the inflatable expansion assembly and the ventilation cavity 3 inside the connecting frame 2, increasing the overall volume of the wrapping layer 4 to ensure the overall sealing effect of the front trunk.

[0026] In some technical solutions, refer to Figure 1 , the inflatable expansion assembly includes: an air charging pipe 5, an air pump 6, and an airbag 7;

[0027] One end of the air charging pipe 5 is embedded in one side wall surface of the connecting frame 2 and is communicated with the ventilation cavity 3. The air pump 6 is fixedly installed at the lower end of the air charging pipe 5. The airbag 7 is installed at the upper end of the connecting frame 2 and is communicated with the upper end of the ventilation cavity 3.

[0028] In this technical solution, through the cooperation of the provided air pump 6 and the air charging pipe 5, the gas is pressurized and transported into the ventilation cavity 3 inside the connecting frame 2. The gas is transported into the airbag 7 through the ventilation cavity 3, and the wrapping layer 4 is expanded by the inflation of the airbag 7.

[0029] In some technical solutions, refer to Figure 1 , a mounting card slot 8 is processed at the bottom end of the mounting frame 1. The air charging pipe 5 is an inflatable hose. A sealing connection block 9 is provided at the connection between the air charging pipe 5 and the connecting frame 2. The wrapping layer 4 is a rubber wrapping layer 4, and both ends of the wrapping layer 4 are respectively connected to the outer walls on both sides of the connecting frame 2 by rivets.

[0030] Working principle: First, fix the installation frame 1 to the rubber strip installation position of the front trunk through the installation slot 8 at the lower end of the installation frame 1, and then place one end of the inflatable expansion component in the front trunk. In daily use of the car, the wrapping layer 4 at the upper end of the connecting frame 2 can meet the daily front trunk sealing needs. In rainy weather, the air pump 6 and the inflation tube 5 are used to pressurize the gas and transport it to the ventilation cavity 3 in the connecting frame 2. The gas is transported to the airbag 7 through the ventilation cavity 3. The airbag 7 is expanded to expand the wrapping layer 4, thereby increasing the overall volume of the wrapping layer 4 and ensuring the overall sealing effect of the front trunk.
