AI Technical Summary

Technical Problem

The sliding door assembly in the existing HVAC unit is prone to torque or torque due to the manufacturing accuracy of gears and racks, resulting in misalignment of the door structure, unable to slide, and friction noise.

Method used

Using a rotary driving structure with a centered position, the rotatable driving body is inserted into the channel of the door structure, and the rotational movement of the rotary driving structure is converted into a linear translation of the door structure through the engagement features, ensuring stable movement of the door structure in the axial direction.

Benefits of technology

It solves the problem of door structure misalignment and inability to slide, reduces friction noise, and improves the manufacturing simplicity and functional stability of sliding door components.

Abstract

The invention relates to an air conditioner for a vehicle and manufacturing thereof. In particular, the present invention relates to a sliding door assembly comprising a door structure having a channel formed therein, the channel extending in an axial direction of the door structure. The first rotary drive structure is configured to selectively rotate about its axis of rotation. The first rotary drive structure includes a first drive body that is rollably received within the passage of the door structure. The engagement feature is configured to convert selective rotation of the first rotary drive structure about its axis of rotation into linear translation of the door structure in its axial direction and relative to the axis of rotation of the first rotary drive structure. The door structure may be formed by an extrusion or pultrusion manufacturing process.
