Description

Frameless door stand assembly and vehicle with same Technical Field The invention relates to the technical field of vehicles, in particular to a frameless vehicle door column assembly and a vehicle with the same. Background With the development of automobiles, consumers have higher and higher requirements on the appearance of the automobiles, and whether the appearance of the automobiles is fashionable becomes an important influencing factor for purchasing the automobiles. While a clean, smooth appearance is an important element of a fashion appearance. Therefore, frameless doors having a smooth appearance are becoming increasingly popular with consumers. The appearance above the waist line of the side surface of the traditional frameless car door is composed of car door glass, car door upright post decorative pieces and sealing strips between the car door glass and the car body upright post decorative pieces. Because the color of the sealing strip is gray and has raised characteristics, the color difference between the sealing strip and peripheral parts is obvious and the appearance is abrupt, and the appearance not only affects the color consistency of the appearance of the side surface of the vehicle door, but also affects the consistency of matching. To solve this problem, hiding the seal strip is an important means of improving the side appearance of the frameless door, while ensuring that the sealing system is matched. The integral frameless door sealing strip in the industry at present can realize smooth and clean appearance design of the side surface without exposing the sealing strip, but has slightly poorer water management and NVH performance (noise, vibration and harshness/Noise, vibration, harshness), so that the problem to be solved in the industry is solved in the rubber water management and NVH performance of the integral frameless door sealing system.
