Description

Technical field

The technical solution concerns a system of accumulation of mechanical energy transformed into the propulsion of mobile means. The technical solution belongs to the field of mechanical engineering.

Prior art

At present, the drive of bicycles, but also of mechanical wheelchairs, depends on the person who uses it for relocation. Such means of transport are also intended for elderly or less active people with disabilities or illnesses. The mechanical wheelchair has the possibility of various variations (hinged and removable side panels, height-adjustable footrests, calf support) and wheels with quick-release axles. The mechanical wheelchair is equipped as standard with brakes for the accompanying person, a folding backrest (for better folding of the wheelchair), a foam seat, which makes sitting on the wheelchair more comfortable and this product ranks at the top of its class, [http://zdravotnickepomocky.eu/katalog / mechanickeinvalidne-voziky / mechanicky-invalidny-vozik-j azzs50-light /].

Mechanical wheelchairs can be four-wheeled or three-wheeled. Four-wheelers are powered by hands, three-wheelers are powered by legs similar to a children's tricycle. In addition, the application of an electric drive is possible. The electric wheelchair makes it easier to control the wheelchair with the control panel on the wheelchair support. The electric wheelchair is designed for long distances. This type of wheelchair is intended for patients with musculoskeletal disorders and patients who are completely paralyzed and able to operate the wheelchair by hand. [h, ttjps: // e-zdrayptBicke

From the available information, it is not known to use the accumulation of mechanical energy to power mobile devices.

The essence of the technical solution

The technical solution concerns a system of accumulation of mechanical energy transformed and subsequently used to support the propulsion of mobile devices. Mobile devices can be bicycles, tricycles and quad bikes designed especially for less active, physically fit people, disabled people, but also children.

The essence of the technical solution is a system of accumulation of mechanical energy into the drive spring, which is spirally shaped. The energy used for the drive is accumulated due to possible deformation by bending the twisted spring into a spiral.

The drive spring is inserted into a cylindrical drum (cover) which is connected by means of a pinion to the drive wheel of the mobile means. By means of the drive wheel, the transmission of the driving force to the fixed pad, on which the mobile means moves, is ensured. The cylindrical drum has toothing around the circumference, so that it also acts on the drive wheel. Energy is accumulated in the spring when the mobile means has a reverse direction of movement. The system of accumulation of mechanical energy is realized through a toothed pinion, which allows accumulation with low torque.

Because the spring is wound on a shaft firmly attached to the frame of the mobile means and its other end is fixed to the inner wall of the cylindrical drum, it continuously develops a driving torque and thus rotates the cylindrical drum connected to the pinion and the drive wheel. The magnitude of the drive torque depends on the degree of torsion of the drive spring. The driving force is transmitted by a pinion, which is co-engaging the toothing and the driving wheel of the mobile means.

The torque of the spring is directly proportional to its thickness. The length of the spring, in turn, determines the total length of the driving force. The most suitable choice of spring material is carbon fibers. The advantage is their flexibility, low weight and minimizing the risk of mechanical damage - cracking.

Industrial applicability

The proposed system uses the accumulated mechanical energy. It can be used wherever an increased pushing force is required to mechanically drive a four-wheeled or three-wheeled wheelchair. The proposed system can also be used for two-wheel bicycles designed for children, as well as for tourist use.
