Description

RELATED APPLICATION The present disclosure claims priority to Chinese Patent Application No. 202311153971.5, filed September 8, 2023, entitled "Weatherstrip Assembly and Vehicle", and Chinese Patent Application No. 202322434965.9, filed September 8, 2023 entitled "Weatherstrip assembly and vehicle". TECHNICAL FIELD The present disclosure relates to the technical field of automotive weatherstrips, and particularly to a weatherstrip assembly and a vehicle. BACKGROUND With the rapid development of the automotive industry, people are increasingly focusing their attention on driving environments with safety guarantees, particularly raising the attention level and the requirements for details. In addition, the competition and the development in industrialization make manufacturers have higher pursuit for the control of production time and the improvement of efficiency. For the production process of automotive parts, simple installation, reliable assembly and high production efficiency are the consistent goals of designers and manufacturers. Currently, most automobiles mainly use the weatherstrips made of stainless steel or aluminum alloy to accentuate vehicle body lines. The weatherstrip, also called a vehicle window trim strip, is one of the most important sealing strips in an automotive sealing system, and it is closely attached to lifting glass of a vehicle window during use to block rainwater from immersing, so as to achieve the functions of anti-leakage, sound insulation, dust prevention, shock absorption and sealing. Since the sealing strip on an outer side of a window sill is exposed outside the window, it serves not only as a sealing member, but also as an appearance trim member, and then high appearance requirements are put forward therefor. Furthermore, in order to improve the overall premium feel of the automobile, the automotive weatherstrip should not only be closely attached to the lifting glass of the window during use to block rainwater from immersing, so as to achieve the functions of anti-leakage, sound insulation, dust prevention, shock absorption and sealing, but also realize simple interactive functions such as luminescence. For example, at present, more and more new energy vehicles and some mid-to high-end models use luminescent elements, which endow the vehicle body with a more futuristic, tech-savvy design. Meanwhile, in nighttime or dim environments, these elements can clearly outline the contour of the vehicle body, thereby further improving the safety during road travel. Conventional luminescent weatherstrips generally require a transparent outer shield for a light guide bar. The outer shield of the luminescent weatherstrip is usually a semitransparent plastic product formed by extrusion or injection molding. The applicant finds that in the actual productization, since the luminescent weatherstrip is installed between a vehicle window glass and a door panel sheet metal, the installation space is small and limited, and the structural design of the outer shield or the like is complicated, which easily leads to the disadvantages of difficult mold machining and poor mass production. SUMMARY Aiming at the defects in the prior art, embodiments of the present disclosure provide a weatherstrip assembly and a vehicle, which can simplify the structure of the mold, increase the production efficiency and greatly improve the mass production of products. Specific technical solutions of the embodiment of the present disclosure are as follows. A weatherstrip assembly for being installed between a vehicle window glass and a door panel sheet metal, including a weatherstrip body and a sealing member. The sealing element extends longitudinally along a first direction, and has an inner surface facing the door panel sheet metal and an outer surface facing away from the door panel sheet metal. The outer surface is provided with a positioning portion. The weatherstrip body as a whole extends longitudinally along the first direction, and is provided with a connecting mechanism, which is connected to the positioning portion and arranged in segments along the first direction. The present disclosure provides a vehicle, including the aforementioned weatherstrip assembly. The present disclosure has the following advantageous effects. The weatherstrip assembly provided in the embodiments of the present disclosure, through structural improvements to the weatherstrip body (i.e., the exterior trim panel and the rear cover), solves the problems such as the excessive number of mold forming mechanisms, difficult machining and poor mass production in existing luminescent weatherstrip structure. It can simplify the mold structure, greatly improve the mass production of products, realize the universal arrangement of the photoelectric module in the space of the plastic weatherstrip assembly, and maintain good photoelectric performance. In addition, the weatherstrip assembly provided in embodiments of the present disclosure cha
