Foldable Display Hinge Guide Rail Structure for Smoother Folding

The patent introduces a new component structure (the improved connection mechanism between the connecting rod and rotating bracket) that acts as an intermediary to transfer the driving force without directly compressing the sliding groove's lower end surface. This mediator structure distributes the compressive load to other parts of the rotating bracket that have higher strength, thereby preventing deformation or breakage of the sliding groove while maintaining the folding function.

The patent applies local quality by strengthening specific areas of the rotating bracket (particularly the regions that bear the compressive load) while keeping other areas optimized for their specific functions. This localized reinforcement ensures that the sliding groove is not subjected to excessive stress, preventing its deformation or breakage, while maintaining the overall folding mechanism's functionality.

The improved connection mechanism serves as an intermediary that smooths out the force transmission during folding. By redistributing the compressive loads away from the sliding groove's vulnerable lower end surface, the mediator structure prevents deformation that would cause folding irregularities, thereby maintaining both folding speed and smoothness.

The patent incorporates design features that preemptively protect against deformation by strengthening the rotating bracket's structure in advance. This prior cushioning approach ensures that when compressive forces are applied during folding, the structure is already prepared to withstand these forces without deforming, thus maintaining folding smoothness.

The improved connection mechanism acts as a stable intermediary that ensures consistent force transmission to both sides of the folding mechanism. By preventing deformation of the sliding groove through proper load distribution, the mediator structure maintains equal and synchronized rotation of both torsion arms, ensuring stable and coordinated operation.

The patent modifies the structural parameters of the rotating bracket and connection mechanism to optimize force distribution. By changing parameters such as wall thickness, material distribution, and geometric configuration in the rotating bracket, the structure achieves better mechanical properties that maintain synchronization stability during rotation while preventing deformation.
