DESC:FIELD OF INVENTION
[001] This application relates to the technical field of an aerial vehicles. More particularly, the present invention relates to an assembly for fixing a motor, mounted on the aerial vehicle, and prevent slippage of the motor due to vibrations occurs during flight of the aerial vehicle.

BACKGROUND OF THE INVENTION

[002] Corona pandemic has made one thing clear, that drones are the future. The pandemic has pushed for digitisation. With this digital shift there is immense opportunity for the drone industry to flourish and grow in the years to come. Businesses across all verticals have started realising the upsides which are the cost efficiency, time saving and technological advancements that drones can weave into a business. Not just commercial but today various examples of drones in development projects show the possibilities of using them in the field of humanitarian aid and environmental protection.

[003] Aerial drones mainly have plurality of arms, propellers and motors mounted on the arms. The motor is fixed on the arms using a motor mount/ seat to ensure that the normal operation drives the propeller to provide flight power for the drone. Conventional motor mount are generally complicated in structure and attached to the drone through screw and bolt fasteners. Due to arm vibration caused by drone’s motion, risk of self-loosening of the screw and bolt connection arises and thereby may disorient the motor mount. Disorientation of the motor may lead to change in thrust direction and further leads to unbalanced forces which can be catastrophic for a drone operation.

[004] Most of the prior arts use friction force between the arm tube and the motor mount to prevent slippage during flight operations or handling of the drone. In some case, apart from friction forces additional fasteners are used to fix the motor mount orientation. This additional fasteners goes through the top mount to the tube and comes out from the bottom mount where a nut is attached to it.

[005] Therefore, keeping in view the problem associated with the state of the art there is a need for an innovative and robust motor mount mechanism/assembly to prevent misaligning and slipping. Further, the proposed motor mount mechanism may orient itself properly and eliminates movement even if the extreme vibrations arise from the drone motion.

OBJECTIVES OF THE INVENTION

[006] A primary objective of the present invention is to provide a self-aligned motor mount assembly for aerial vehicle which prevent orientation due to vibrations during flight of the aerial vehicle.

[007] Another objective of the present invention is to provide the self-aligned and anti-slippage motor mount assembly, thereby improving assembly process of the motor and drone vehicle.

[008] Yet another objective of the present invention is to provide the highly reliable motor mount assembly having four independent failure points.

[009] Yet another objective of the present invention is to provide the motor mount assembly which prevent both rotational and translation movement during assembly and flight operations.

[0010] Yet another objective of the present invention is to provide a motor mount assembly having simple and aesthetic design.
