Description

The name of the utility model: "Universal vehicle". Further, in the text of the description, the utility model is called abbreviatedly - "UTS".

The utility model relates to the field of vehicles capable of moving in various environments (all-terrain vehicles, amphibians, etc.) and can be used as a vehicle suitable for transportation by land, air and water.

It is known from the prior art that airboats, paragliders and snowmobiles are propelled by the use of a propeller engine propelling the jet in the direction opposite to the direction of travel of the vehicle. At the same time, in airboats, the direction of movement is changed due to the rudders located behind the propeller, in aerosleds due to steering skis.

Other attempts to create hybrid vehicles are known. For example, the German company Fresh Breeze produces a Flyke vehicle that travels on the road like a tricycle, but is capable of flying thanks to a soft wing of a motorized paraglider and an internal combustion engine with a pushing propeller: http://www.fresh-breeze.de/ en / products / trikes / flyke.html.

Despite some advantages of this apparatus (independent movement on the ground and in the air), there is an incomplete hybridization. So, if the propeller was driven by an electric motor, it would be possible to install motor-wheels, also powered by electricity, and common storage batteries instead of a fuel tank. Also known is the design of a tricycle manufactured by Hase Bikes. It provides for the installation of a carriage electric motor with a small battery, as well as a large luggage bag behind the pilot, in addition, the payload of this tricycle can reach 140 kg: https://hasebikes.com/144-l-Recumbent-Bike-KETTWIESEL-CROSS-STEPS .html #.

However, this tricycle can only travel on the ground.

The task of creating this useful model was the design of a trainer for movement on land (electric tricycle, snowmobile), air (paramotor) and water (glider), while its driving performance (speed, traction, ergonomics, streamlining) would not be affected at all.

(speed, traction, ergonomics, streamlining) would not be affected at all.

To solve this problem, it is necessary to implement the following technical solutions:

- take as a basis a tricycle or quad bike that can withstand a significant weight;

- to develop and equip it with floats and skis installed on wheels or instead of them;

- to develop and equip it with an electric power plant with a propeller;

- equip the apparatus with a soft paragliding wing of the appropriate size and with appropriate attachments.

Thus, the essence of the utility model is such an arrangement of support and power systems based on a tricycle, which will provide a mobile restructuring of the apparatus for the tasks of movement on land, on water or in air.

The TCB can, in principle, be created on the basis of a tricycle bicycle with a recumbent seat of the pilot, using batteries, a looped propeller with an electric motor on the axis, as well as special skis, which can be put on, if necessary, on the wheels of the tricycle (or by removing the front wheel and a rear axle with wheels and installation of a front ski with attachment to the front wheel fork and axles with attachments for two skis to the rear wheel fork). For flights, the TCB is equipped with a soft paragliding wing, which is attached with slings to special mounts on the TCB. In addition, a looped power plant is installed on the TCB platform behind the pilot's seat, as described by the author in the application for invention No. 2020117633. The specified power plant consists of a propeller in a ring (which, due to its aerodynamics, can increase the thrust of the propeller up to 30%), on the axis of which there are an electric motor and a controller (the ring has multifunctional mounts for placing the power plant on aerosleds, paragliders, speedboats, gyroplanes, airplanes, motor hang gliders ) and battery packs in sealed boxes.

Thus, due to the choice and correct arrangement of the TCB elements, it acquires the ability to swim, slide on the snow, move like an electric bike and fly.

The following calculations show the effectiveness of using the specified TCB.

The aerodynamic quality of motor paragliders is from 5 to 10 units (on average - 8). At the same time, the take-off thrust on sports models reaches 80 kgf. Takeoff and climb time is about 2 minutes. Thus, for a flight for about an hour (the average time of using a motorized paraglider), it is necessary to provide 80 kgf during takeoff and about 20 kgf in cruise mode (which corresponds to a takeoff weight of 160 kg with an aerodynamic quality of 8 units). Lithium-ion batteries (for example SONY 18650 VTC6) have rechargeable batteries each capable of delivering up to 12 kW each and having an energy reserve of more than 1 kWh each. A circular propeller with a diameter of 80 cm and an electric motor weighing about 3 kg can provide a take-off thrust of 80 kgf with an energy consumption of 24 kW, and in cruise mode (20 kgf) will consume about 3 kW. This means that a flight in the form of 2 (a minute take-off and further movement "in the horizon" with four battery cases (with a total weight of about 15 kg) can last about 66 minutes. The total mass of the power plant will be about 30 kg: 10 kg - looped propellers with electric motor and controller and 20 kg battery cases, while the petrol engine units used by paragliders weigh 25-30 kg and a gas tank with fuel another 15-20 kg. the prices of the fuel used The total take-off weight is the weight of the tricycle (less than 30 kg), the weight of the pilot (90 kg), the weight of the power plant (30 kg), the weight of the wing (5 kg) and is thus 155 kg, which corresponds to the takeoff the mass for which the power plant is designed (in the case of a paramotor).

As for the use of the TCB as a snowmobile. There are already skis on the market that are mounted on the front wheels of bicycles, while a wide tire is installed on the rear wheel and then a fairly comfortable ride on the snow is possible (http://bikeboards.net). If you install similar skis on all three wheels at once on a tricycle with a sufficient distance between the rear wheels, plus install the power plant described above, you will get an electric snowmobile, while when the skis are removed, the aerosled will turn back into a bicycle. As for the installation of floats, their dimensions are not difficult to calculate. The mass of the displaced water must exceed the mass of the apparatus. Let the mass of the displaced water be 220 kg (which certainly exceeds the mass of the apparatus of 155 kg, even if the mass of the floats themselves is 20 kg). Taking into account the density of the water (1 kg / 1 l), the volume of each of the three floats must be at least 73.33 liters. Such a volume will turn out, for example, if the length of the float is 1200 mm, and the width and length are equal to 246.5 mm.

In addition, the current situation is such that there are practically no electric gliders, snowmobiles and paratrikes on the market.

The technical result of using the TCB will be the creation of such a device that will allow you to move on land, water and air, satisfying the various needs of the consumer.

The description does not include figures.

The utility model can be materialized by applying the device diagram described above, as well as using the materials described below.

TCB can be materialized as follows:

1. The bike tricycle can be taken as a basis for the already existing Big Dandy 24 (https://www.youtube.com/watch?v=DNKuqrp0RDQ).

2. Two L-shaped brackets for attaching the lines of the paragliding wing are attached to the luggage platform of the indicated cycle tricycle.

3. The paragliding wing is used in the same way as on conventional paratrikes, it is attached to the L-shaped brackets, taking into account the center of the aircraft.

4. The universal electric power plant (already created by the author www.skyward-moto.ru) consists of a carbon-fiber ring with fasteners, on the axis of which an electric motor, a propeller, a controller, a control lever are located, also contains battery cases and is placed behind the tricycle pilot's seat in the luggage compartment platform. 5 Bicycle skis, can be purchased from the supplier (http://bikeboards.net) or made independently from skateboards, contain eyelets for fastening with straps to the wheels of the tricycle and are installed, respectively, on the specified wheels.

6. Bicycle floats can be made of polystyrene reinforced with fiberglass, attached to the wheels of the tricycle with lugs and straps.

7. An auxiliary electric motor can be installed in the front hub of the tricycle as an option for easier overland travel.

8. The auxiliary motor controller can also be installed as an option to regulate the operation of the auxiliary motor.

9. The auxiliary motor control joystick can also be installed as an option to control the operation of the auxiliary motor controller.

To use the TCB as a ground vehicle, bicycles (5) or bicycle floats are removed (6) and placed on the luggage platform behind the pilot's seat (the universal electric power unit (4) can also be removed). The pilot moves using pedals or an auxiliary electric motor (7). To move on water or snow, the pilot installs, respectively, bicycle skis (5) or bicycle floats (6) and a universal power plant (4), thanks to which the movement takes place. For flight, the pilot attaches the paragliding wing (3) to the L-shaped brackets and a universal electric power plant (4), after which he performs takeoff and takeoff, as in a conventional paratrike.

Thus, the utility model "Universal vehicle" makes it possible to create an apparatus capable of moving on land, water and in the air.
