AI Technical Summary
Outward-sliding sunroofs lack effective restraint at the rear when opened, resulting in poor stability and making it easy for rainwater to enter the vehicle.
The design incorporates a liftable main guide rail and a fixed secondary guide rail. The lifting mechanism controls the movement of the movable bridge, ensuring that the sunroof is flush with the roof when closed and aligned with the secondary guide rail when open. The combined structure of the movable and fixed bridges ensures stable support and precise sliding at the rear of the sunroof.
It improves the stability of the sunroof when it slides outwards, prevents rainwater from entering the vehicle, and ensures the smoothness and stability of the sunroof's sliding motion.

TECHNICAL FIELD
[0001] The application relates to the technical field of automobile sunroofs, in particular to an automobile sunroof guide rail with auxiliary guidance. BACKGROUND
[0002] There are two opening modes of automobile sunroofs, one is the inner sliding type, which makes the movable sunroof slide under the cover plate behind the roof, and this mode occupies more space on the top of the car; the other is the outer sliding type, which makes the movable sunroof slide to the top of the cover plate behind the roof, and this mode makes the opened sunroof protrude from the roof, and the sunroof cannot be in contact with the roof to scratch the paint, so it can only be fixed by the front restraint structure, and the sunroof is unstable due to the lack of restraint at the rear end. SUMMARY
[0003] The application aims to provide an automobile sunroof guide rail which can provide restraint for the tail of the sunroof when it is sliding out.
[0004] To achieve the above purpose, the application provides an automobile sunroof guide rail with auxiliary guidance: a pair of configuration frames are fixedly connected with a fixed bridge on the opposite sides, and a fixed sunroof is fixedly connected between the two fixed bridges; each configuration frame is further connected with a movable bridge through a lifter; an active sunroof is slidably connected above the two movable bridges; when the movable bridge is lowered to the lower limit position, the upper surface of the active sunroof is flush with the upper surface of the fixed sunroof; when the movable bridge is raised to the upper limit position, the rear end of the movable bridge is aligned with the front end of the fixed bridge, and the active sunroof is adapted to pass through the joint of the movable bridge and the fixed bridge and slide on the fixed bridge, so that the tail of the sunroof can be stably supported and restrained when it is opened by sliding out.
[0005] As a preferred, the movable bridge comprises a main guide rail, the bottom of the main guide rail has a movable plate, the tail end of the movable plate has a lap plate which exceeds the main guide rail, the fixed bridge comprises a secondary guide rail, the bottom of the secondary guide rail has a fixed plate, the front end of the fixed plate is provided with a gap slot below the secondary guide rail, which is adapted to fit with the lap plate and provide accurate positioning when the main guide rail and the secondary guide rail are connected.
[0006] As a preferred, the fixed sunroof comprises a top cover, the two sides of the top cover have downwardly extending flow baffles, the flow baffles are fixedly connected with the fixed plate to form a drainage groove on the fixed plate, and the rainwater entering the auxiliary guide rail can be guided to the tail of the car.
[0007] As a preferred, the configuration frame comprises a side baffle, the side baffle is also fixedly connected with the fixed plate to form a drainage groove on the fixed plate, which is also used to provide a moving space for the sliding foot of the active sunroof.
[0008] As a preferred, the bottom of the side baffle has a supporting plate, and the lifter is fixedly connected to the supporting plate to keep the position of the lifter stable.
[0009] As a preferred, the top of the side baffle has a mounting plate, and a connecting hole is formed in the mounting plate to pass through a connecting member such as a bolt, so that the configuration frame is fixed in the reserved frame of the roof.
[0010] As a preferred, the front ends and the rear ends of the two movable bridges are fixedly connected with synchronous beams, and the movable end of the lifter is fixedly connected to the bottom surface of the synchronous beam, so that the two movable bridges are driven to synchronously rise or fall.
[0011] As a preferred, the lifter is an electric telescopic rod, and has good position control accuracy.
[0012] Compared with the prior art, the application has the following beneficial effects:
[0013] (1) The main guide rail is designed to be liftable, and the fixed auxiliary guide rail is designed on the roof. When the window is closed, the main guide rail is lowered, and the movable sunroof is flush with the roof. When the window is opened, the main guide rail is raised and aligned with the auxiliary guide rail, and the movable sunroof can slide along the main guide rail and the auxiliary guide rail at the same time. This makes the tail end of the movable sunroof located above the roof effectively supported and constrained, thereby improving the stability of the sunroof when the window is opened.
[0014] (2) The tail end of the movable bridge and the front end of the fixed bridge are designed to be matched, and the height is controlled by the lifter, so that the main guide rail and the auxiliary guide rail can be accurately aligned, and the smoothness of the movable sunroof sliding on the aligned complete guide rail is ensured.
