[0017] Beneficial effects of the present invention:

[0018] (1) During the use of the rear hatch door sealing structure of the present application, it is convenient to install the rear hatch door body hinge on the rear hatch door frame. The rear hatch door frame and the rear hatch door body can be sealed by the door frame seal. However, the hinge connection part and the wiring connection part at the top of the rear hatch door body are prone to sealing hazards. The hinge top of the rear hatch door body of the present application is sealed with the rear hatch door frame by the door body seal. Under the action of the double sealing connection structure of the door frame seal and the door body seal, the rear hatch door can meet the requirements of sealing, sound insulation and rainwater blocking, thereby ensuring the sealing of the rear hatch door;

[0019] (2) When the rear hatch door body is hinged to the rear hatch door frame, the rear hatch door is closed to the installation groove for limit position. At this time, the door frame seal is clamped between the sealing contour surface of the rear hatch door body and the hatch branch opening to achieve sealing of the contour edges around the rear hatch door body;

[0020] (3) When the rear hatch door is hinged to the rear hatch frame, the door seal is clamped between the upper sealing groove and the upper stop to achieve outer sealing of the hinge connection part and the wiring connection part, and to achieve sealing of the hinge hole and the wiring harness hole, thereby ensuring the sealing of the rear hatch door;

[0021] (4) The door frame seal and the door body seal can be foamed rubber strips or foamed silicone tubes. Foamed rubber strips or foamed silicone tubes are rubber products with a porous structure. During the production process, a foaming agent is added to the rubber and a large amount of gas is generated during the vulcanization process to form a material with a large number of small holes inside. This material has the characteristics of light weight, softness, elasticity, and low heat conduction, so as to meet the requirements of sealing, sound insulation and rainwater blocking for the rear door;

[0022] (5) The through-type taillight also has a sealing risk due to the existence of internal wiring. The through-type taillight is sealed when installed in this application to ensure the sealing effect at the position of the through-type taillight. BRIEF DESCRIPTION OF THE DRAWINGS
