Description
Technical Field
[0001] This utility model relates to the field of automotive design and manufacturing technology, specifically a sliding door lower guide rail baffle structure. Background Technology
[0002] When installing a sliding door, the lower hinge needs to be inserted into the lower guide rail through a notch at the rear end. To prevent the lower hinge from sliding out of the notch when the door is opened, a lower guide rail baffle is needed to block it. Current technology involves inserting a baffle limiting bracket into the front end of the lower guide rail baffle. A flange is added to the lower end of the bracket to prevent the baffle from falling off, thus restricting the baffle's Y and Z directions. A spring-loaded nut is added to the rear end of the lower guide rail to hold it in place. The rear end of the baffle is then fixed to the spring-loaded nut and the lower guide rail using a hexagonal flange bolt.
[0003] However, most existing technologies have the following drawbacks:
[0004] ① The front end of the baffle plate is limited in the Z direction by the flange of the bracket. If the limiting is not firm, it is easy to fall off.
[0005] ②The spring nut has low strength, resulting in poor stability of the baffle plate.
[0006] ③ The baffle is a thin strip of sheet metal, which is relatively weak.
[0007] Therefore, in view of the above situation, there is an urgent need to provide a lower guide rail baffle structure for automobile sliding doors to overcome the shortcomings in current practical applications. Utility Model Content
[0008] The purpose of this utility model is to provide a guide rail baffle structure for automobile sliding doors, which aims to solve the problems mentioned in the background art.
[0009] This utility model is implemented as follows: a sliding door lower guide rail baffle structure includes a sliding door lower guide rail baffle fixed on a sliding door lower guide rail assembly. The sliding door lower guide rail assembly includes a sliding door lower guide rail rear reinforcing plate and a sliding door lower guide rail installed within the sliding door lower guide rail rear reinforcing plate. The sliding door lower guide rail baffle is provided with a sliding door lower guide rail baffle flange, and the rear end of the sliding door lower guide rail baffle is connected to the sliding door lower guide rail rear reinforcing plate through a connecting component. The sliding door lower guide rail rear reinforcing plate is provided with an X-direction guiding insertion structure for inserting the front end of the sliding door lower guide rail baffle, and the sliding door lower guide rail rear reinforcing plate is also provided with a Z-direction insertion and limiting structure for inserting the sliding door lower guide rail baffle flange.
[0010] As a further embodiment of this utility model: the connecting component includes a nut and a bolt for use with the nut, the nut is disposed inside the rear reinforcing plate of the lower guide rail of the sliding door, and a circular hole communicating with the nut is provided on the rear reinforcing plate of the lower guide rail of the sliding door.
[0011] As a further embodiment of this utility model: the lower guide rail baffle of the sliding door is provided with a second round hole for bolts to pass through.
[0012] As a further embodiment of this utility model, the bolt is a hexagonal flange bolt.
[0013] As a further embodiment of this utility model, the nut is welded and fixed to the inner wall of the rear reinforcing plate of the lower guide rail of the sliding door.
[0014] As a further embodiment of this utility model, the three inner sides of the rear reinforcing plate of the sliding door lower guide rail are welded and fixed to the sliding door lower guide rail.
[0015] As a further embodiment of this utility model: the rear reinforcing plate of the lower guide rail of the sliding door and the lower guide rail of the sliding door are provided with a notch for facilitating the installation of the lower guide rail baffle.
[0016] As a further embodiment of this utility model: a second notch corresponding to the first notch is provided on the lower guide rail of the sliding door.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] The front end of the sliding door lower guide rail baffle is inserted into the X-direction guide insertion structure of the rear reinforcing plate of the sliding door lower guide rail to achieve Y-direction limitation of the front end of the sliding door lower guide rail baffle. The front end of the sliding door lower guide rail baffle is inserted into the Z-direction insertion and limitation structure of the rear reinforcing plate of the sliding door lower guide rail through the flange, thereby achieving Z-direction limitation of the front end of the sliding door lower guide rail baffle. The rear end of the sliding door lower guide rail baffle is fixed to the sliding door lower guide rail assembly by hexagonal flange bolts.
[0019] When assembling the sliding door lower guide rail baffle, first insert the flange of the sliding door lower guide rail baffle into the sliding door lower guide rail assembly along the Y direction, then insert the front end of the sliding door lower guide rail baffle into the sliding door lower guide rail assembly from the rear along the X direction, and finally tighten the hexagonal flange bolts to fix it.
[0020] The rear end of the sliding door's lower guide rail baffle is fixed with a projection weld nut, which provides better stability than a spring-loaded nut.
[0021] The addition of a flange to the lower guide rail baffle of the sliding door increases the strength of the lower guide rail baffle itself; on the other hand, the flange provides Z-axis limiting, resulting in better stability. Attached Figure Description
