Description

TECHNICAL FIELD

[0001] The utility model relates to a car door, in particular to a car sliding door hinge guide rail structure. BACKGROUND

[0002] With the passage of time, the development speed of society is changing day by day. Cars have also become an indispensable means of transport for people, and with development, consumers are also paying more attention to the quality of cars, especially the quality of high-end business cars. Especially under the impact of the modeling of new energy cars today, it is relatively difficult for the modeling of traditional MPVs to break through.

[0003] In the existing MPV car design, the traditional sliding door usually adopts a three-point structure type guide rail system, upper, middle and lower hinge guide rail structures, to ensure the stability of the door during opening and closing. However, this fixed installation form limits the modeling design of the vehicle roof, affecting the overall appearance and design flexibility of the vehicle, and the modeling is relatively simple.

[0004] To solve this problem, some manufacturers have tried to use a double guide rail solution (i.e. only the middle and lower guide rails are retained) to improve the flexibility of the vehicle roof modeling. However, after removing the upper guide rail, the door is prone to shaking during opening and closing, resulting in a decline in user experience and potential safety hazards. Although increasing the hinge stiffness can improve the stability of the door to some extent, this method alone cannot completely solve the problem, so a new solution is needed to ensure the stability of the door and the flexibility of the vehicle roof modeling.
