[0027] To describe in detail the technical content, achieved objectives, and effects of the present utility model, the following is described in conjunction with the embodiments and with reference to the accompanying drawings.

[0028] To achieve a better sealing effect, a lip structure is provided on the edge of the injection-molded edge during the injection molding process, and the lip structure is overlapped with the vehicle body. However, after the sunroof assembly is connected to the vehicle body, the lip structure of the sunroof assembly will deform and press against the vehicle body sheet metal. When the vehicle is driving on rough roads and twisted roads and other poor road conditions, the vehicle body sheet metal will collide with the lip and generate abnormal noises, affecting the passengers' experience.

[0029] Please refer to Figures 1 - 3 , based on this, a vehicle is proposed, including a sunroof assembly and a vehicle body sheet metal. The sunroof assembly is arranged on the top of the vehicle body sheet metal; the sunroof assembly includes glass 2 and an edge 1, and the edge 1 wraps around the edge of the glass 2; the edge 1 includes an edge body 11; at least one edge of the edge body 11 has a lip 12, and a support portion 13 for contacting the vehicle body sheet metal is arranged on the side of the lip 12 facing the vehicle body sheet metal. Preferably, the material of the edge 1 is PU.

[0030] It can be understood that by arranging the support portion 13 at the part where the lip 12 contacts the vehicle body sheet metal, direct contact between the lip 12 and the sheet metal is prevented. On the one hand, the contact area between the lip 12 and the vehicle body sheet metal can be reduced, and on the other hand, the deformation amount of the lip 12 can be increased, the pressing force between the lip 12 and the vehicle body sheet metal can be increased, the probability of collision between the lip 12 and the vehicle body sheet metal can be reduced, and the probability of abnormal noise can be reduced or even eliminated. The abnormal noise generated when the vehicle of the present utility model is driving on poor road conditions is significantly reduced, improving the comfort of passengers.

[0031] In some embodiments, the support portion 13 includes a first protrusion 131 and a second protrusion 132; in the width direction of the lip 12, the first protrusion 131 and the second protrusion 132 are arranged alternately. Optionally, the first protrusion 131 and the second protrusion 132 can be multiple respectively, and all the first protrusions 131 and all the second protrusions 132 are arranged in sequence along the length direction of the lip 12. Through the arrangement of the first protrusion 131 and the second protrusion 132, the contact area between the lip 12 and the vehicle body sheet metal is greatly reduced, and the multi-point contact method can enable the lip 12 to stably abut against the vehicle body sheet metal, that is, the lip 12 can obtain good support on the vehicle body sheet metal. The above-mentioned staggered arrangement of the first protrusion 131 and the second protrusion 132 specifically means that with the width direction of the lip as the axis, the first protrusion 131 and the second protrusion 132 are respectively arranged on both sides of the axis, and the first protrusion 131 is located at a position close to the edge of the lip, while the second protrusion 132 is located at a position farther from the edge of the lip relative to the first protrusion 131.

[0032] In some embodiments, the first protrusion 131 and the second protrusion 132 are strip-shaped, spherical, conical or cylindrical. When the first protrusion 131 and the second protrusion 132 are spherical and conical, the contact area between the first protrusion 131 and the second protrusion 132 and the body sheet metal is the smallest, and the probability of generating abnormal noise is also reduced.

[0033] In some embodiments, the distance between the first protrusion 131 and the second protrusion 132 is 1 mm to 3 mm. Specifically, the distance between the first protrusion 131 and the second protrusion 132 refers to the distance between their axes. Optionally, the distance can be 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, 2.5 mm, 2.8 mm or 3 mm. Preferably, the distance is 1.5 mm.

[0034] In some embodiments, the distance between two adjacent first protrusions 131 and the distance between two adjacent second protrusions 132 are both 1 mm to 3 mm. Optionally, the distance between two adjacent first protrusions 131 and the distance between two adjacent second protrusions 132 can be the same or different. Optionally, the distance between two adjacent first protrusions 131 and the distance between two adjacent second protrusions 132 are equal, both being 3 mm. If the distance between the first protrusion 131 and the second protrusion 132, the distance between two adjacent first protrusions 131, and the distance between two adjacent second protrusions 132 are too large, the supporting force of the protrusions on the lip 12 will decrease, and further the probability of generating abnormal noise will increase. Preferably, the number of the first protrusions 131 and the second protrusions 132 is equal.

[0035] In some embodiments, the height of the first protrusion 131 and / or the second protrusion 132 is 0.2 mm to 2 mm. If the height of the protrusion is too high, the distance between the lip 12 and the body sheet metal will be too large and other noises will be generated. If the height of the protrusion is too small, there is still a certain probability that the lip 12 will contact the body sheet metal and abnormal noise will be generated. Optionally, the height of the first protrusion 131 and / or the second protrusion 132 is 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm or 2 mm. Preferably, the height of the first protrusion 131 and the second protrusion 132 is equal, both being 0.2 mm.

[0036] In some embodiments, the supporting portion 13 and the lip 12 are integrally injection-molded to improve the structural stability. Specifically, the first protrusion 131 and the second protrusion 132 are integrally injection-molded with the lip 12.

[0037] In some embodiments, the first protrusion 131 and the second protrusion 132 are respectively in smooth transitional connection with the lip 12. Specifically, chamfers can be designed at the ends of the first protrusion 131 and the second protrusion 132 close to the lip 12, so that the first protrusion 131 and the second protrusion 132 are respectively in smooth transitional connection with the lip 12. Correspondingly, chamfers are designed in the injection molds of the first protrusion 131 and the second protrusion 132. Then, when the first protrusion 131, the second protrusion 132 and the lip 12 are injection molded, the molten material has good fluidity in the injection mold, avoiding defects such as air bubbles and material shortage on the first protrusion 131 and the second protrusion 132 during the molding process.

[0038] In some embodiments, the support portion 13 is distributed along the edge portion of the lip 12. Since the contact position between the lip 12 and the vehicle body sheet metal is located at the position close to the edge portion of the lip 12, the support portion 13 is arranged along the edge portion of the lip 12, which can completely isolate the lip 12 from the vehicle body sheet metal and minimize the probability of abnormal noise generation.

Preferably, the material of the wrap-around edge 1 is PU.

[0041] In this embodiment, the support portion 13 includes a first protrusion 131 and a second protrusion 132; in the width direction of the lip 12, the first protrusion 131 and the second protrusion 132 are arranged in a staggered manner. Refer to Figure 2 and Figure 3 , as a preference, there are two groups of the first protrusions 131 and one group of the second protrusions 132, that is, each group of the first protrusions 131 and each group of the second protrusions 132 are respectively provided with four. Each group of the first protrusions 131 and each group of the second protrusions 132 are distributed along the length direction of the lip 12; the first protrusion 131 and the second protrusion 132 are spherical.

[0042] In this embodiment, the support portion 13 is distributed along the edge portion of the lip 12. Specifically, the first protrusion 131 is distributed close to the edge portion of the lip 12, and the lip 12, the first protrusion 131 and the second protrusion 132 are integrally injection molded.
