Description

Technical Field

[0001] The utility model relates to a paraglider, in particular to an electric paraglider. Background Art

[0002] An electric paraglider is a paraglider equipped with an electric power unit. In 1978, French mountaineer Mr. Bétain invented the paraglider, making the human dream of soaring into the blue sky come true. However, while people were delighted, they found that the flying of a paraglider was still far from the free flying in their dreams. The most important point was that it could not take off and land freely on flat ground. Takeoff was restricted by the conditions of the hillside, which made flying enthusiasts in areas without mountain peaks feel uncomfortable. In 1984, a group of French paragliding enthusiasts who were full of romance and fantasy added a small engine to the paraglider. The engine was used to drive the thrust of the propeller and the lift of the paraglider wing, making "free takeoff and landing" on flat ground no longer a problem. They achieved their goals of flying higher, farther, and staying in the air longer, thus creating this emerging aviation sport.

[0003] Existing paragliders have the following disadvantages:

[0004] 1. Existing paragliders have only a single propeller assembly. When the propeller rotates, it generates torque, causing the direction to deviate and ultimately causing the operator to follow the deflection. Some paragliders have two propeller assemblies driven by the same motor, which makes the internal transmission structure complex.

[0005] 2. Existing paragliders have poor support for the motor and propeller mounting structures, posing certain risks.

[0006] 3. The blades of existing paragliders are an integrated structure and need to be locked with fasteners after being installed. If two sets of blade assemblies are installed, it is impossible to remove a single blade from one end, which makes installation and removal inconvenient;

[0007] 4. Existing paragliders lack a power release device. In exceptional circumstances, such as spontaneous combustion of the power supply, the power supply cannot be released to protect the pilot.

[0008] 5. The existing paraglider protective cover is an integrated structure. During installation and removal, it is affected by the drive assembly and blade assembly and cannot be installed and removed separately, resulting in low installation and removal efficiency.

[0009] 6. Existing paragliders are not equipped with passive safety devices, such as warning lights and ultrasonic sensors. They are unable to provide warnings and passively control the drive components when encountering other flyers and obstacles, making it impossible to avoid risks in advance. Utility Model Content
