Increase Impact Resistance of Drones

A motor designed for unmanned aerial vehicles (UAVs) to prevent damage when landing on rough terrain. The motor has a hub with a skid surface that contacts the motor casing during propeller strikes on the ground. This reinforcement prevents excessive bending of the rotor shaft, which could damage the motor.

Removable protection for quadcopter drones that provides propeller protection without adding bulk when not needed. The protection consists of removable lateral bumpers that extend beyond the propeller's rotation area. A deformable arm connects Each bumper to the drone's propulsion units on that side. The arm can flex if the bumper hits an obstacle, reducing shock and preventing damage.

A drone battery casing made of a lattice structure that provides improved protection and heat dissipation compared to traditional casings. The casing is made of nano-ceramic aluminum alloy and has a periodic lattice structure. It replaces machined casings made of materials like PC or aluminum. The lattice structure enhances stiffness and force resistance while dissipating heat better than solid casings. The lattice casing provides better protection for the drone battery during flight compared to traditional casings.

An unmanned aerial vehicle (UAV) with a protective outer cage provides high collision resistance while allowing maneuverability and access to inner components. The UAV has an inner frame with flight propulsion, an outer frame connected by a gimbal system, and an actuation system to actively orient the outer frame relative to the inner frame. This allows the outer cage to protect inner components from collisions while still reaping benefits like protection from the outer frame. The actuation can be through outer propellers or electrical actuators on the gimbal connections.

Full carbon fiber unmanned aerial vehicle body that uses interspersed glue joints between modular sections to create a lightweight, high-strength, and easily assembled body structure. The modular sections are made of carbon fiber composite material to reduce weight compared to metal bodies. The interspersed glue joints involve inserting an interspersed block into a slot on one section and fixing it with high-temperature glue. Then bolts are used for additional fixation. This allows modular sections to be spliced together into a complete body. The modular design enables customization and repairability while the carbon fiber composite material provides lightweight strength.

A vibration damping structure for unmanned aerial vehicles (UAVs) to improve flight stability and prevent damage to the flight control system from high-frequency vibrations. The damping structure uses multiple layers of shock-absorbing sponges sandwiched between positioning sheets and housings. The sponges are bonded to the flight control components and housings. The sponges are made of materials like viscose and glass fiber to provide anisotropic damping. The housings have positioning bosses and holes to securely mount the damping components. The sponges are positioned between the control components and housings to absorb vibrations in all directions.

Double monocoque structure for drones that enhances strength and waterproofing while allowing easy exterior customization. The drone has an internal monocoque covering the frame from above and below, with an external monocoque doubling over the internal one. This provides a double-layered monocoque structure around the drone components like wings, legs, and power source. The monocoque construction increases strength and waterproofing compared to just attaching lids to the frame. The double monocoque allows customizable outer shapes by changing the external monocoque design.

A UAV architecture that provides improved thrust efficiency, mass reduction, protection, and internal cooling for unmanned aerial vehicles (UAVs). The architecture uses a foam-polycarbonate composite airframe with enclosed cores and a central support frame. The foam cores are vacuum formed polycarbonate shells overmolded with expanded polystyrene foam. This provides lightweight, impact-resistant airframe components. The enclosed cores shield internal components from damage. The support frame physically couples the cores and motors. The architecture enables upside-down landing/takeoff, buoyancy, and internal cooling through the foam cores.

Heat dissipation system for multi-rotor drones that allows customized heat dissipation and protection for different drone models. The system has a detachable heat sink fan mounted on the drone body, with a sliding adjustment rod to raise or lower the fan height. The fan slides in a frame that connects to the drone body. This allows the user to adjust the fan position based on drone size to ensure proper cooling. The system also has a buffer assembly at the drone bottom with a stopper, spring, cushion, and anti-collision pads to absorb impacts and protect the battery. This prevents damage when the drone lands.

Unmanned aerial vehicle (UAV) with a protective outer cage and a sensor system like a camera. The cage protects the inner components from collisions, but can interfere with sensors and cameras. To solve this, the UAV has a releasable coupling between the sensors and the cage. The coupling is rigid in normal operation, but can release when subjected to a collision force above a threshold. This allows the sensors to be decoupled from the cage upon impact, protecting them from damage.

Modular multi-rotor drone design that allows quicker repair and continued operation after damage by separating high-voltage components from low-voltage components. The high-voltage components like batteries and motors are located outside the drone body. This protects them from damage during crashes. The low-voltage components like electronics and sensors are inside the body. If a high-voltage component fails, it can be quickly replaced without disassembling the entire drone. This enables faster repairs and allows the drone to be back in service sooner.

Improved motor hub and pod configurations for protecting propellers of unmanned aerial vehicles (UAVs) from damage during flight. The motor hub features a central hub with slots to receive carbon fiber spokes that extend radially outward to a protective outer ring. The spokes are oriented to resist flexure out of the plane of rotation, reducing the chances of blade strikes. The pod incorporates a rugged protective structure with ribs, hoops, and rims to encase the propellers. The motor hub and pod designs are lightweight, durable, and resistant to impacts that can damage conventional UAVs.

Shockproof unmanned aerial vehicle (UAV) to prevent internal components from vibrating and jumping during flight. The UAV has a fuselage, main rotor, tail rotor, engine, and reduction gearbox. The main rotor is directly connected to the fuselage, while the tail rotor is connected to the fuselage via a fixed shaft inside the fuselage.

A drone (uninhabited airborne vehicle) that reduces impact when it crashes to enhance safety. The drone has a buffer system to protect it from damage in case of a crash. The buffer system can be activated based on parameters such as battery charge level, altitude, distance to objects, and velocity. It wraps around the drone to absorb impact forces during a crash. The buffer driving process is activated when sensors detect conditions indicating a crash is imminent. This allows the drone to land with reduced impact forces to prevent damage.
