Problems solved by technology
At present, there are few practical designs in the field of wheel brakes. Most applications do not have relevant brake mechanisms, and they slide directly, which greatly extends the length of the runway.
Due to the particularity of the UAV wheel, it is required to be able to fold, so the space folding problem needs to be considered when using a rigid mechanism, and the wheel is required to be light and easy to fold, and the catapult take-off requires the wheel to be firmly braked, so the traditional The brake disc mechanism is insufficient, bulky, frictional and heat-generating, not suitable for use on drones

The invention provides a machine wheel braking mechanism for a miniature unmanned aerial vehicle. The machine wheel braking mechanism mainly comprises a machine wheel braking component and a remote hydraulic control component, and is characterized in that braking is performed not by traditional forced sliding friction, no-friction braking is realized through cooperation between a specially-shaped cavity and a suspension rack, and the kinetic energy of a machine wheel is no longer converted into frictional heat energy to be dissipated, but elastic potential energy to be stored. The machine wheel braking mechanism has the remarkable characteristics that no frictional heating is generated, rapid braking is realized, meanwhile, neither the weights nor the complexity of the machine wheel or attachments of the machine wheel is increased, folding collection during a flight is facilitated, and the machine wheel braking mechanism can also be used for catapult-assisted take-off of the unmanned aerial vehicle.
Description
technical field [0001] The invention provides a small unmanned aerial vehicle wheel braking mechanism, which belongs to the field of small unmanned aerial vehicle wheel braking mechanism design. Background technique [0002] The development and application of small unmanned aerial vehicles and high-end aircraft models are becoming more and more popular in both military and civilian fields. The design of corresponding alignment parts and related functional mechanisms is also becoming more and more important. Efficiently ensuring their work is the first requirement. At present, there are few practical designs in the field of wheel brakes. Most applications do not have relevant brake mechanisms, and they slide directly, which greatly prolongs the length of the runway. Due to the particularity of the UAV wheel, it is required to be able to fold, so the space folding problem needs to be considered when using a rigid mechanism, and the wheel is required to be light and easy to fol...
