[0005] Preferably, the base is also provided with a drainage channel for draining water accumulated in the installation groove.

[0006] Preferably, the upper door seal, the left door seal and the right door seal are all connected with ribs.

[0007] Preferably, the lower parts of the left door seal and the right door seal are connected with a bracket, and the cross-section of the bracket is L-shaped.

[0008] Preferably, a barrier rod is overlapped on the bracket.

[0009] Preferably, the lower door seal comprises a port.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are:

[0011] The utility model is provided with a base whose top surface is flush with the road surface, and the lower door seal is hidden in the base, and the lower door seal is driven in and out of the base by a driving motor, thereby avoiding collision with the rear bumper of the car.

[0012] The utility model is provided with a drainage channel to prevent the accumulated water in the installation groove from being unable to be discharged. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0018] like Figure 1 As shown, an inflatable door seal includes an upper door seal 1, a left door seal 2, a right door seal 3, and an air pump (not shown in the figure). Simply put, the inflatable door seal is inflated by the air pump to inflate the airbag in the door seal, so that the airbag overlaps the car body, thereby preventing outside air from entering the cold storage. In order to block the lower part of the car body, the utility model also includes a base 4 arranged below for docking with the road surface, the base 4 is provided with a mounting groove 41, a lower door seal 42 is arranged in the mounting groove 41, and the lower door seal 42 is connected to a rotating shaft at one end close to the platform 8. A hidden drive motor 43 is also arranged in the base 4, and the drive motor 43 and the rotating shaft can be connected through a coupling. The drive motor 43 can drive the lower door seal 42 to rotate, so that it enters the mounting groove 41 or stands up. A pillar 44 for supporting the lower door seal 42 is also arranged in the mounting groove 41.

[0019] Specifically, since vans generally have a rear bumper, the lower door seal 42 of the utility model is hidden in the base 4. When the rear bumper of the van passes over the lower door seal 42 and the van stops, it is erected under the drive of the drive motor 43, and the airbag in the lower door seal 42 is inflated and pops up to seal the bottom of the car.

[0020] Furthermore, the base 4 is also provided with a drainage channel 45 for draining the water accumulated in the installation groove 41 .

[0021] Furthermore, the upper door seal 1, the left door seal 2, and the right door seal 3 are all connected with ribs 5 to enhance the connection stability with the wall.

[0022] In order to prevent the driver from forgetting to activate the handbrake, thereby causing the vehicle to slip away from platform 8.

[0023] Furthermore, the lower parts of the left door seal 2 and the right door seal 3 are connected with a bracket 6, and the cross section of the bracket 6 is L-shaped.

[0024] Furthermore, a stop bar 7 is overlapped on the bracket 6, and the stop bar 7 is at the same level as the rear bumper. Specifically, the rear bumper of the truck passes between the two brackets 6, and after the lower door seal 42 is erected, the stop bar 7 is placed on the two brackets 6, so that after the vehicle slips, the stop bar 7 can block the rear bumper.

[0025] Furthermore, the lower door seal 42 includes a port 421 away from the platform 8 , and the port 421 is beveled to facilitate the lower door seal 42 to be screwed into the installation groove 41 .

[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
