[0039] Embodiment 1

[0040] The present embodiment relates to a convertible roof sealing structure, which is used to seal the gap between the roof 10 and the front windshield 13, and the sealing structure includes a sheet metal part 2 arranged on a body sheet metal 1, and a sealing strip arranged on the sheet metal part 2. The sealing strip includes a base part 3, a first sealing part 4, an extension part 5 and a second sealing part 6.

[0041] Among them, the base 3 is connected to the sheet metal part 2, and the first sealing part 4 is connected to the left side of the base 3 and abuts against the left end of the ceiling 10. The extension part 5 is connected to the side of the first sealing part 4 close to the front windshield 13, and extends in the direction of the front windshield 13, and abuts against the front windshield 13. The second sealing part 6 is connected to the right side of the base 3 and abuts against the bottom of the ceiling 10. The first sealing part 4, the second sealing part 6 and the ceiling 10 are surrounded to form a U-shaped water guide channel extending along the width direction of the vehicle. Rainwater passing through the contact position between the first sealing part 4 and the ceiling 10 can flow to the left and right sides of the vehicle body through the guidance of the water guide channel, and in the specific implementation, corresponding drainage structures can be provided on the left and right sides of the vehicle body, such as a sealing bubble tube connected to the water guide channel, etc., which can flow to the outside of the vehicle, which is conducive to achieving a better sealing effect.

[0042] Based on the above overall introduction, as a preferred implementation method, Figures 1 to 3As shown, in this embodiment, the sheet metal part 2 is disposed below the ceiling 10 and can be connected to the body sheet metal 1 by bolts 9. The sheet metal part 2 is L-shaped and has a connecting body 201 connected to the base 3, and a positioning part 202 connected to the left end of the connecting body 201 and extending to the upper left.

[0043] In order to facilitate the connection between the sealing strip and the sheet metal part 2 and to facilitate the installation of the sealing strip on the vehicle body, as a preferred embodiment, the base 3 includes a base body and a group of claws 301 arranged at the bottom of the base body and clamped on the connecting body 201, and a clamping groove 204 is arranged on the connecting body 201 to clamp the claws 301. In specific implementation, Figure 1 As shown in the figure, two claws 301 are arranged at intervals at the bottom of the base body, and the two claws 301 and the base body form a V-shape with the opening downward. By making the two claws 301 and the base body form a V-shape, it is convenient to set the above-mentioned bolts 9, and it can also make the sealing strip have a better structural strength. Of course, in this embodiment, a group of claws 301 is only provided as a preferred implementation. In addition, the claws 301 can also be provided at the bottom of the connection body and arranged in multiple groups at intervals along the left and right directions.

[0044] In addition, as a preferred implementation, Figure 1 and Figure 2 As shown in FIG. 1 , in this embodiment, glass fiber filaments 302 extending in the vehicle width direction are embedded in the base body. This arrangement is beneficial to improving the overall strength of the sealing strip and can also prevent the sealing strip from shrinking during use.

[0045] like Figure 1 As shown in , a positioning groove is provided at the position where the extension portion 5 is connected to the first sealing portion 4, the opening of the positioning groove is arranged toward the lower right, and the positioning portion 202 is inserted into the positioning groove. By providing the positioning groove and inserting the positioning portion 202 into the positioning groove, the positioning of the sealing strip during installation is facilitated, and the positioning portion 202 can also support the first sealing portion 4, so that when the roof 10 of the convertible is unfolded and the end of the convertible is pressed against the first sealing portion 4, the positioning portion 202 can support the first sealing portion 4, thereby ensuring that the first sealing portion 4 has a good direct contact effect with the top, which is conducive to achieving better sealing performance.

[0046] In addition, in order to ensure a good connection effect between the positioning portion 202 and the positioning groove, Figure 1 As shown in , the end of the positioning portion 202 is engaged with the bottom of the positioning groove, thereby preventing the positioning portion 202 from escaping from the positioning groove.

[0047] A first transition section 203 is connected between the positioning portion 202 and the connecting body 201 , a second transition section 7 is connected between the first sealing portion 4 and the base 3 , the second transition section 7 is covered above the first transition section 203 , and a cavity 8 is formed between the second transition section 7 and the first transition section 203 .

[0048] When implementing it, Figure 1 and Figure 2 As shown in the figure, the first transition section 203 is the rounded transition portion between the positioning portion 202 and the top of the card slot 204, the second transition section 7 is the inclined connection portion between the first sealing structure and the base 3, and the cavity 8 is formed by the first transition section 203 and the second transition section 7. And as a preference, in this embodiment, a first notch 701 is formed on the side of the second transition section 7 away from the cavity 8.

[0049] By forming the above-mentioned cavity 8, when the first sealing portion 4 is subjected to the pressure of the ceiling 10, the position of the second transition section 7 of the sealing strip arches and bends in the direction of the cavity 8 due to the force transmitted from the first sealing portion 4, and the bending deformation of the second transition section 7 can transmit the leftward force to the second sealing portion 6 via the base 3, so that the second sealing portion 6 is more tightly pressed against the right end portion of the bottom of the ceiling 10, thereby enhancing the sealing effect between the second sealing portion 6 and the ceiling 10.

[0050] In addition, Figure 2 and Figure 3 As shown in , as a preferred embodiment, in this embodiment, the first sealing portion 4 includes a first sealing bubble tube, and the second sealing portion 6 includes a second sealing bubble tube. The left end of the ceiling 10 abuts against the right side of the first sealing bubble tube. And the right end of the bottom of the ceiling 10 abuts against the second sealing bubble tube. And in the specific implementation, a second notch 401 is formed on the inner wall of the first sealing bubble tube, and the second notch 401 is located below the abutment position of the first sealing bubble tube and the ceiling 10. A third notch 601 is formed on the inner wall of the second sealing bubble tube, and the third notch 601 is located below the abutment position of the second sealing bubble tube and the ceiling 10.

[0051] By making the first sealing portion 4 include the first sealing bubble tube, it is convenient to have sufficient interference when the ceiling 10 and the first sealing bubble tube abut against each other, thereby avoiding the risk of sealing failure between the two in extreme cases. And by providing the first notch 701, when the first sealing bubble tube is pressed by the ceiling 10, the first notch 701 can guide the first sealing bubble tube to bend inward at the position where the first notch 701 is located, so that the ceiling 10 can have a larger contact area when abutting against the first sealing bubble tube, so as to achieve a better sealing effect.

[0052] In addition, if Figure 1 and Figure 2As shown in the figure, a right-angled bending portion 402 is formed on one side of the first sealed bubble tube close to the second transition section 7, and the right side of the bending portion 402 is connected to the first notch 701. In this way, when the first sealed bubble tube is pressed by the sealing portion and bent at the position of the first notch 701, the bending portion 402 will be subjected to a rightward pulling force, so that the above-mentioned second transition section 7 can be bent from the position of the first notch 701 and arched toward the direction of the cavity 8, and then transmitted to the second sealed bubble tube The force acting to the left, thereby improving the sealing performance between the second sealed bubble tube and the ceiling 10.

[0053] In addition, by making the second sealing portion 6 include the second sealing bubble tube, it is convenient to have sufficient interference when the bottom of the ceiling 10 abuts against the second sealing bubble tube. And by providing the third notch 601, it is convenient to make the second sealing bubble tube bend at the position of the third notch 601 under the pressure of the ceiling 10, which is conducive to increasing the contact area between the bottom of the ceiling 10 and the second sealing bubble tube, thereby improving the sealing performance between the second sealing bubble tube and the ceiling 10. It should be noted that in addition to providing the third notch below the abutment position of the ceiling 10 and the second sealing bubble tube, a notch can also be provided at other positions on the inner wall of the second sealing bubble tube.

[0054] like Figure 1 As shown in , in the specific setting, the extension part 5 is set in accordance with the body sheet metal 1, and the extension part 5 has an abutting section 501 abutting against the lower surface of the front windshield 13, and a water guide groove 502 extending along the width direction of the vehicle is provided on the abutting section 501. By making the abutting section 501 abut against the lower surface of the front windshield 13, it is convenient to realize the hidden setting of the abutting position of the sealing strip and the front windshield 13, thereby facilitating the improvement of the aesthetics of the position. And by providing the water guide groove 502, it is beneficial to improve the sealing effect of the abutting position of the sealing strip and the front windshield 13.

[0055] In addition, if Figure 1 As shown in FIG. 1 , in this embodiment, a lip 11 extending obliquely downward is further provided near the position where the second sealed bubble tube is connected to the base 3 , so as to shield the boundary of the interior decoration 12 .

[0056] The convertible car roof sealing structure of the present embodiment is provided with a first sealing portion 4 and a second sealing portion 6, and a water guide channel is formed between the first sealing portion 4 and the second sealing portion 6, which is beneficial to improving the sealing effect of the sealing structure and further improving the riding experience of passengers.
