UAV Remote Control Lever Assembly With Integrated Dust Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controls for unmanned aerial vehicles are prone to external sand and moisture ingress due to their split-type rotating structure, which compromises user experience through poor aesthetics and lack of intuitive control lever rotation feedback.
Innovation Solution
A remote control design featuring a control lever assembly with a housing, rotating member, and a dust-proof cover that shields the rotating member, preventing external contaminants and enhancing the intuitive rotation feel, while maintaining a sealed and optimized appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a split-type rotating structure is used for the control lever, then the control lever can be assembled with multiple components, but external sand, dust or moisture may easily enter the remote control through gaps
Solution Approach 1:
The dust-proof cover is nested inside the control lever assembly, with the cover body positioned within the housing and the dust-proof ring extending outward to seal against the housing wall. This nested configuration allows the dust-proof cover to be integrated into the existing control lever structure without adding external protrusions, preventing sand, dust or moisture from entering through gaps while maintaining a compact design.
Solution Approach 2:
The dust-proof cover employs a flexible sealing structure consisting of a cover body and a dust-proof ring that can deform to maintain contact with the housing wall. The flexible nature of this sealing structure allows it to adapt to slight variations in assembly tolerances and maintain effective sealing against external contaminants throughout the operational life of the remote control.

If a split-type rotating structure is used for the control lever, then the control lever can be assembled with multiple components, but the appearance and intuitive feeling of rotation are not ideal
Solution Approach 1:
The dust-proof cover is nested inside the control lever assembly, with the cover body positioned within the housing and the dust-proof ring extending outward to seal against the housing wall. This nested configuration allows the dust-proof cover to be integrated into the existing control lever structure without adding external protrusions, preventing sand, dust or moisture from entering through gaps while maintaining a compact design.

3Object-affected harmful factors
If a dust-proof cover is added to shield the rotating member, then external contaminants are prevented from entering, but the device complexity increases
Solution Approach 1:
The dust-proof cover is merged with the control lever assembly as an integrated component rather than a separate external addition. The cover body and dust-proof ring form a unified sealing structure that is positioned within the existing housing and control lever components, combining the dust-proofing function with the existing mechanical structure to minimize overall device complexity.
Solution Approach 2:
The dust-proof cover is nested inside the control lever assembly, with the cover body positioned within the housing and the dust-proof ring extending outward to seal against the housing wall. This nested configuration allows the dust-proof cover to be integrated into the existing control lever structure without adding external protrusions, preventing sand, dust or moisture from entering through gaps while maintaining a compact design.

AI summary
The present invention relates to the field of an unmanned aerial vehicle, and provides a remote control including: a remote control body and a control lever assembly at least partially accommodated in the remote control body; the control lever assembly including: a housing disposed in the remote control body; a rotating member disposed in the housing and rotatably connected to the housing; and a control lever connected to the rotating member, the control lever driving the rotating member to rotate around at least one direction relative to the housing; and the control lever having a handle and a dust-proof portion connected to the handle, the rotating member being connected to the dust-proof portion, the dust-proof portion being partially accommodated in the housing, and the rotating member being shielded by the dust-proof portion. Through the control lever assembly of the remote control, on the one hand, some external sand or moisture may be prevented from entering, on the other hand, an appearance of the control lever assembly may be better optimized, and the user who performs an operation may intuitively feel that the control lever rotates around a rotating center, providing better user experience.
