Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is the U.S. National Phase under 35 U.S.C. § 371 of International Application No. PCT/CN2020/140394, filed Dec. 28, 2020, titled SIDE DOOR WINDOW STRUCTURE OF MOTOR VEHICLE, the entirety of each of which is hereby expressly incorporated by reference herein. TECHNICAL FIELD The invention relates to a side door window of a motor vehicle. BACKGROUND ART In current side door window structures the outer surface of the side door window glass is usually executed with an offset between an outer surface of an outside glass pane and an outer styling surface of the vehicle body. This leads to an uneven appearance of the vehicle body, but body excellence is a key selling point for high class and luxury vehicles. Additionally, does the uneven body surface lead to air turbulence at the edges, which lead to a higher energy consumptions when driving and an increased background noise in comparison to a body without height differences. CN 209 938276 U reveals a solution wherein the side glass window comprising a laminated glass with two glass panes, namely an inside glass pane and an outside glass pane. The outer surface of the outside glass pane is arranged flush with an outside surface of the side doorframe. However, it is increasingly desirable to design doors without a frame. SUMMARY OF INVENTION Technical Problem Therefore, the task of the invention is to overcome the disadvantages of the state of the art and provide a side glass window structure, which enables a flush positioning of the side glass window to the vehicle body. SOLUTION TO PROBLEM Technical Solution Main features of the invention are specified as follows. The invention concerns a side door window structure of a motor vehicle, comprising a side door with a side door window and an area of vehicle body, which is arranged close to the side door window, wherein the side door window is moveable upward and downward and arranged frameless in the side door, wherein the side door window comprising at least two glass panes, an inside glass pane and an outside glass pane, wherein an upside end of the outside glass pane is lower than an upside end of the inside glass pane, wherein an outer surface of the outside glass pane is arranged flush with an outer surface of a roof skin of the vehicle body and/or any attached to the roof skin decorative trim part in a closed mode of the side door and the side door window, wherein, inside glass pane, especially the upside end of the inside glass pane, reaches in the closed position of the side door and the side door window inside a channel and the outside glass pane is arranged outside the channel in the closed position of the side door and the side door window. The definition of the arrangement of the inside glass pane, outside glass pane and outer surfaces takes place from a view of the vehicle interior. The inside glass pane is oriented to the inside of the vehicle. The outside glass pane is oriented to the outside of the vehicle. The area of vehicle body is formed by the side door window surrounding parts of the vehicle body, for example parts of the roof top. The roof skin forms the outer surface of the roof top. The invention leads to a side door window structure for a frameless arrangement, wherein an outer surface of the side door window is at least flush with an outer surface of the roof skin of the vehicle body. This lead to an even appearance of the vehicle outside and the vehicle body. This is of special relevance for high-class and luxury vehicle. While opening the side door of the inventive side door window structure, the side door window is moved upwards for the length of the inside glass pane which is inside the channel. The movement of the side door window is for example linked to the operation of the door handle. In a preferred embodiment, the channel is attached to an end area of the roof top, especially to an end area of the roof skin. Especially, the outer surface of the channel is arranged flush with the outer surface of the roof skin. This leads to an even appearance of the vehicle surface. Preferably, the attached channel is hold by an end area of the roof skin, which is folded around an ending of the outer side wall of the channel. In an alternative embodiment, the roof skin forms the channel, especially the channel is formed by folded sheet material of the roof skin. Through this embodiment, the channel is flush with the roof skin, because it is formed out of the roof skin. This is an easy and inexpensive way to produce a channel for the inside glass pane of the side door window. In a preferred embodiment, the channel has an essentially U-shape. Especially, is the channel formed as an upside down U with an open side showing downwards. Preferably, the U-shaped channel is formed by three essentially rigid walls, an inner side wall, an outer side wall and a middle, connecting wall. The inner side wall and the outer side wall may have different leg le
