[0055] Specifically, refer to Figure 6 As shown, the buckle 43 includes a columnar body, one end of which is connected to the lower corner 41 of the sealing strip, and a claw is provided at the other end of the columnar body. The buckle 43 forms a conical structure at the claw to facilitate the insertion of the buckle 43 into the clamping hole 22. During the insertion of the buckle 43 into the clamping hole 22, the claw is pushed by the clamping hole 22 to shrink toward the columnar body; after the claw passes through the buckle 22, the claw returns to the initial state, and the free end of the claw abuts against the surface of the second side wall 21 away from the lower corner 41 of the sealing strip, that is, the insertion of the buckle 43 into the clamping hole 22 is completed. And because after the buckle 43 is inserted into the clamping hole 22, the free end of the claw abuts against the surface of the second side wall 21 away from the lower corner 41 of the sealing strip, the buckle 43 is not easy to fall out of the clamping hole 22, so that the connection structure between the lower corner 41 of the sealing strip and the second side wall 21 is stable.

[0056] Optional, see Figure 6 As shown, an elastic protrusion 44 is provided on the lower corner 41 of the sealing strip, and the elastic protrusion 44 is arranged around the buckle 43, and the elastic protrusion 44 abuts against the second side wall 21. In the above structure of the embodiment of the present application, the elastic protrusion 44 can increase the clamping force after the buckle 43 is clamped into the clamping hole 22, thereby preventing the lower corner 41 of the sealing strip from being loosely connected with the lower outer guard plate 2 of the rear door.

[0057] Specifically, refer to Figure 6 As shown, the elastic protrusion 44 is arranged around the buckle 43, and the elastic protrusion 44 abuts against the second side wall 21, so that the free end of the claw of the buckle 43 is deformed and kept abutting against the surface of the second side wall 21 away from the lower corner 41 of the sealing strip. After the buckle 43 is inserted into the clamping hole 22, the clamping force increases, and the second side wall 21 is clamped between the elastic protrusion 44 and the claw of the buckle 43, which can effectively avoid the problem of loose connection between the lower corner 41 of the sealing strip and the lower outer guard plate 2 of the rear door.

[0058] Optional, see Figure 5 As shown, there is a second gap 73 between the lower corner 41 of the sealing strip and the second side wall 21 .

[0059] Further references Figure 5As shown, the elastic protrusion 44 abuts against the second side wall 21. The elastic protrusion 44 is a surface of the lower corner 41 of the sealing strip that protrudes toward the second side wall 21. The elastic protrusion 44 allows a second gap 73 to exist between the lower corner 41 of the sealing strip except for the remaining part of the elastic protrusion 44 and the second side wall 21. The second gap 73 can avoid assembly difficulties and interference between the rear door outer lower guard plate 2 and the lower corner 41 of the sealing strip caused by the accumulation of automobile manufacturing tolerances.

[0060] Further references Figure 5 As shown, in the second gap 73 between the lower corner 41 of the sealing strip and the second side wall 21 in the width direction of the automobile, the inner end of the second gap 73 extends to the end of the second side wall 21 away from the first side wall 23, that is, the inner end of the second gap 73 is connected to the first gap 72. The outer end of the second gap 73 extends to the step structure formed between the first side wall 23 and the second side wall 21.

[0061] Optional, see Figure 6 As shown, the shielding portion 42 includes a first free end 48 and a second free end 49; in the front-to-rear direction of the automobile, the first free end 48 is located at the front side of the shielding portion 42, and the second free end 49 is located at the rear side of the shielding portion 42, and the length of the first free end 48 is greater than the second free end 49; the first free end 48 extends toward the front door outer lower guard plate 1 and extends into the boundary of the front door outer lower guard plate 1, for shielding the appearance gap 71; the second free end 49 abuts against the first side wall 23 of the rear door outer lower guard plate 2.

[0062] Further references Figure 5 As shown, in the front-to-back direction of the car, the positive X direction is the front side of the car, and the negative X direction is the rear side of the car. The first free end 48 is located at the front side of the shielding portion 42, and the second free end 49 is located at the rear side of the shielding portion 42. The first free end 48 extends into the boundary of the front door outer lower guard plate 1 to achieve the purpose of shielding the appearance gap 71, and can avoid the appearance defects of the inner side panel 6 being seen through the appearance gap 71. Figure 1 , which shows a schematic diagram of the structure after the shielding portion 42 shields the appearance gap 71. The second free end 49 can achieve sealing between the shielding portion 42 and the rear door outer lower guard plate 2, and improve the sealing effect between the sealing strip lower corner 41 and the rear door outer lower guard plate 2.

[0063] Specifically, the direction of looking toward the inside of the vehicle through the appearance gap 71 between the outer side wall of the front door outer lower guard plate 1 and the outer side wall of the rear door outer lower guard plate 2 is a reference. Figure 5 When looking into the vehicle through the appearance gap 71, only the shielding portion 42 can be seen, and the side panel 6 located inside the appearance gap 71 cannot be seen.

[0064] In the embodiment of the present application, the shielding portion 42 includes a first free end 48, which is located at the front side of the shielding portion 42 and is relatively long. When the front door is closed, the front door outer lower guard plate 1 on the front door contacts the first free end 48 when the front door passes through, and presses the first free end 48 to move into the vehicle. After the front door is closed, the first free end 48 returns to its initial state.

[0065] Further, when the front door and the rear door are closed, the front door outer lower guard plate 1 can contact the first free end 48 on the shielding portion 42; Figure 5 As shown, there is a gap between the front door outer lower guard plate 1 and the first free end 48 on the shielding portion 42. This gap can prevent the front door outer lower guard plate 1 from squeezing the first free end 48 after the front door is closed, thereby reducing damage to the first free end 48 and extending the service life of the first free end 48 and the lower corner 41 of the sealing strip.

The lower side of the front door sheet metal 5 is connected to the front door outer lower guard plate 1, and the lower side of the rear door sheet metal 3 is connected to the rear door outer lower guard plate 2. The sealing strip 4 includes a sealing strip upper section 46 and a sealing strip lower corner 41, and the sealing strip upper section 46 and the sealing strip lower corner 41 are connected. The sealing strip upper section 46 is connected to the upper sheet metal edging 31 of the rear door sheet metal 3, and the sealing strip upper section 46 is used to seal the gap between the upper side of the front door sheet metal 5 and the upper side of the rear door sheet metal 3. The sealing strip lower corner 41 is located between the front door outer lower guard plate 1 and the rear door outer lower guard plate 2, and the sealing strip lower corner 41 is connected to the rear door outer lower guard plate 2. For further reference Figure 5 As shown, the end of the lower corner of the sealing strip 41 in the positive direction of the Y direction is provided with a shielding portion 42, and the front end of the shielding portion 42 extends into the range of the front door outer lower guard plate 1. The shielding portion 42 can shield the appearance gap 71 between the outer wall of the front door outer lower guard plate 1 and the outer wall of the rear door outer lower guard plate 2, thereby visually shielding the appearance gap 71, and avoiding the appearance defect of the inner side surrounding sheet metal 6 being seen through the appearance gap 71. The end of the lower corner of the sealing strip 41 in the negative direction of the Y direction wraps the sheet metal edging 31, so as to realize the connection between the lower corner of the sealing strip 41 and the sheet metal edging 31. The lower corner of the sealing strip 41 is connected to the rear door outer lower guard plate 2, which can avoid the appearance distortion of the lower corner of the sealing strip 41 due to the distortion of the sheet metal edging 31 when the lower corner of the sealing strip 41 is connected to the sheet metal edging 31 of the rear door sheet metal 3 on the inner side of the rear door outer lower guard plate 2, and the defect of poor connection quality between the lower corner of the sealing strip 41 and the sheet metal edging 31.
