[0002] With the rapid development of society and the popularization of automobiles, consumers' requirements for the appearance and shape of automobiles are constantly increasing, so the configuration of automobiles also needs to be improved accordingly. Skylights are adopted by many car companies as a configuration that can increase the lighting area and improve the appearance quality.

[0003] Most skylights use PU edging that is integrally injected around the glass, which is expensive. Therefore, solutions such as using sealing strips to replace the PU edging that is integrally injected around the glass are gradually emerging. However, the appearance quality cannot be guaranteed, especially at the corners of the skylight glass. For those with a small corner radius, wrinkles will appear after the existing sealing strip structure turns. Therefore, the corner joint is generally adopted, but the existing corner joint requires a corner joint mold, and there are cracks or poor strength at the joint. Summary of the invention

[0006] Preferably, the sealing strip is in strip shape and is located at the edge of the inner surface of the automobile sunroof glass, and is used to seal the transverse gap between the edge of the sunroof glass and the vehicle body.

[0007] Preferably, the sealing strip includes a front sealing strip, a rear sealing strip, and left and right side sealing strips.

[0008] Preferably, the corner radius of the skylight glass is ≤R40.

[0009] Preferably, the first hole at the lower end of the corner turn is a circular hole or an elliptical hole.

[0010] Preferably, the second hole on the platform is a circular hole or an elliptical hole.

[0011] Preferably, the joint is a TPV hard glue joint or an EPDM hard glue joint.

[0013] (1) The corner joint structure of the automotive sunroof sealing strip of the utility model is an L-shaped corner joint, and a first hole is provided at the lower end of the turning part thereof to prevent the wall thickness of the local area of ​​the corner joint from being too thick, avoid shrinkage marks, and ensure a good appearance of the corner joint.

[0014] (2) In the utility model, the two ends of the corner of the automobile sunroof sealing strip joint structure are respectively connected to sealing strips, and the two ends of the corner are trapezoidal grooves. One end of the sealing strip connected to the corner is provided with a protrusion matching the trapezoidal groove. The contact surface between the corner and the sealing strip is trapezoidal, so that the contact area of ​​the two contact surfaces is increased, thereby enhancing the butt strength.

[0015] (3) In the corner joint structure of the automotive sunroof sealing strip of the utility model, an L-shaped platform with a certain thickness and an arc is provided on the back side of the corner joint. The platform and the sealing strip are integrally formed to enhance the tear strength of the corner joint, so that the force value is controlled above 100N, which can prevent the corner joint and the sealing strip from cracking, and greatly extend the overall life of the sunroof sealing strip.
