TECHNICAL FIELD

[0001] The utility model relates to an automobile part, concretely relates to a lower hinge clamping guide rail structure of automobile sliding door. BACKGROUND

[0002] In automobile design, the traditional sliding door usually adopts three guide rail systems, including upper guide rail, middle guide rail and lower guide rail, to ensure the stability of the door during opening and closing. However, the existence of the upper guide rail seriously limits the modeling design of the vehicle roof, affecting the overall appearance and design flexibility of the vehicle. In order to solve this problem, some manufacturers try to adopt a double guide rail scheme (i.e. only the middle guide rail and the lower guide rail are reserved) to improve the flexibility of the vehicle roof modeling. However, after removing the upper guide rail, the door is prone to shaking during closing, resulting in a decline in user experience. 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.
