Description

(Cross-reference of related applications) This application claims priority to the Chinese patent application with patent application number 202210762585.5, filed on June 30, 2022, and titled "Vehicle Door Glass Assembly, Vehicle Door Assembly and Vehicle". This invention relates to the vehicle technology field, and more particularly to vehicle door glass assemblies, vehicle door assemblies, and vehicles. Currently, widely used flush vehicle door glass assemblies have guide frames attached to the front and rear ends of the vehicle door glass. These guide frames are secured to a seal strip on the vehicle door sheet metal rail, and the outer surface of the vehicle door glass is flush with the seal strip. That is, the inner surface of the vehicle door glass, the guide frame, and the edge of the vehicle door glass are connected to the seal strip, while the outer surface of the vehicle door glass is not. While the guide frame and seal strip work together to provide better guidance for the lift slide of the vehicle door glass, and the engagement of the guide frame and seal strip during vehicle operation stabilizes the glass, preventing it from shaking due to airflow, a jamming phenomenon exists in the lift slide of the glass. The glass can easily be offset in its extension direction, and wear on one end of the seal strip can cause leaks of air and water.

The following describes the technical proposals according to embodiments of the present invention more clearly and completely with reference to the drawings of embodiments of the present invention. Of course, the embodiments described below represent only a portion of the present invention, and the present invention is not limited thereto. Any other embodiments that can be obtained by those skilled in the art without innovative ingenuity based on the embodiments of the present invention should be understood to fall within the scope of the present invention. (Example 1) As shown in Figure 1, the present invention provides a vehicle door glass assembly comprising: a vehicle door body; a vehicle door glass 1 that is sealed to the vehicle door body and slidably fitted along the vertical direction Z, having a first end 11 and a second end 12 facing each other in the longitudinal direction X, moving in the vertical direction Z by the drive of a lifting mechanism 9, with the point of force reception between the lifting mechanism 9 and the vehicle door glass 1 being the main support point O; and a weight structure 2 mounted on the vehicle door glass 1, wherein the weight structure 2 adjusts the center of gravity O1 of the vehicle door glass 1 as it moves along the vertical direction Z, so that the torque generated with respect to the main support point O by the force received by the vehicle door glass 1 is balanced with respect to each other. The vehicle door glass assembly of the present invention is provided with a weight structure 2 on the vehicle door glass 1. As the vehicle door glass 1 moves along the vertical direction Z, the weight structure 2 adjusts the center of gravity of the vehicle door glass 1. This ensures that the torque generated by the force acting on the vehicle door glass 1 relative to the main support point O between the vertical mechanism 9 and the vehicle door glass 1 is balanced. This increases the stability of the less stable end of the vehicle door glass 1 and prevents it from tilting towards the more stable end. As a result, the vertical mechanism 9 can drive the vehicle door glass 1 and slide smoothly along the vertical direction Z, preventing jamming and avoiding the formation of a gap between the less stable end of the vehicle door glass 1 and the vehicle door body, thus preventing the seal between the vehicle door glass 1 and the vehicle door body from being broken. Specifically, the vehicle door glass 1 may be the front door glass 1 or the rear door glass 1. Due to the streamlined design of the vehicle body, the vehicle door glass 1 has an asymmetrical structure with respect to its center of gravity, resulting in a large difference in stability between the first end 11 and the second end 12 of the vehicle door glass 1. Therefore, by providing the weight structure 2, the stability of the les
