Ceiling handle assembly and vehicle

By designing the torsion spring and linkage components in the ceiling handle assembly, the rotation range of the handle body is limited, and large torque is prevented from being transmitted to the drive device. This solves the problem of damage to electric drive handles under high pulling force and achieves stability and durability of transmission components and drive device.

AI Technical Summary

Technical Problem

Existing electric vehicle roof handles are prone to damage and failure when subjected to large pulling forces, such as damage to transmission components or internal components of the drive motor.

Method used

Design a ceiling handle assembly including a drive unit, a transmission component, a torsion spring, a linkage component, a handle body, and a mounting base. By designing the torsion spring and linkage component, the rotation range of the handle body is limited to avoid large torque being directly transmitted to the drive unit. Limiting components and gear dampers are used to ensure stable rotation.

Benefits of technology

This effectively avoids damage to transmission components or internal components of the drive motor caused by excessive tension, ensuring the stability and durability of transmission components and drive devices.

Abstract

The application relates to a roof handle assembly and a vehicle, which comprises a shell, a driving device, a transmission assembly, a torsional spring, a linkage assembly, a handle body and a mounting seat; the handle body comprises a rotating shaft part and a holding part, the axis of the rotating shaft part is perpendicular to the outer surface of the mounting seat; the linkage assembly comprises a main shaft and a force receiving part which are fixedly connected; the transmission assembly comprises an output shaft connected with the driving device and a force applying part sleeved on the main shaft, the force applying part is axially fixed with the force receiving part and can relatively rotate in the circumferential direction; the torque is transmitted between the force applying part and the force receiving part through the torsional spring; when the handle body is not loaded, the movement of the driving device can drive the force applying part to rotate, the force applying part drives the force receiving part and the handle body to rotate through the torsional spring. The application has the beneficial effect that when the handle body is subjected to a destructive torque, the handle body and the base have a hard limiting point, the destructive torque cannot be transmitted to the inside of the driving device through various transmission parts, and the transmission parts or the parts in the driving device cannot be damaged and failed.
