FOLDABLE INFLATABLE VEHICLE

Description

[0001] The present invention aims to create a foldable inflatable vehicle, with a passenger compartment, where only the wheel support frames and the wheel are not inflatable. Said wheel support frames are held by the inflation pressure of certain parts of the vehicle. The motors and energy storage are at the level of the wheels and the wheel support frame. The controls are removable, such as turning, accelerating, braking, lights and horn. Technical field

[0002] The present invention relates to a foldable inflatable vehicle which is as light as possible and which takes up the minimum space when deflated. Prior art

[0003] There is a search to make vehicles lighter, and we see the first vehicles, notably scooters, with an inflatable chassis and speeds below 10 km / h. There are also patents for an inflatable dummy vehicle and others where only part of the structure is inflatable. Summary of the invention

[0004] To achieve its goal, the invention proposes different solutions that can be used separately or combined partially or all together depending on the advantages that one wishes to highlight, in particular a solar electric foldable inflatable vehicle of which only the wheel support frame and the wheel are not inflatable. Technical problem

[0005] Vehicles are heavy, which means high energy consumption; they also take up space for transport and storage; then the slightest shock results in significant repair costs; finally, it is not easy to change the design of your vehicle. Technical solution

[0006] The entire upper structure, that is, everything above the floor or chassis, is inflatable and has at least one inflatable passenger compartment, it is fixed on the low platform and said structure is composed of inflatable beams and uprights, fabric doors and / or a fabric grille and / or sides partially closed by the fabric bodywork, which allow the passenger compartment to be partially closed.

[0007] The seats are incorporated into the upper structure to reduce space requirements and cost.

[0008] The floor is inflatable, completely flat and starts at the front and ends at the rear of the vehicle.

[0009] An inflatable platform chassis composed of several inflatable elements, assembled together, some inflatable elements have a pressure relief valve with different trigger levels, in order to guide, in the event of impacts, the deformation by elements which deflate first, others later and others which must maintain the rigidity of the passenger compartment. These inflatable elements can be used to frame and maintain the engine support structure and / or the structure to hold the wheels.

[0010] The controls are removable and can include a joystick, steering wheel, pedals or a handle.

[0011] The wheel support frame is composed of a solid shape comprising at least one U which is held to the inflatable shape, like a vice, by the inflation pressure of said inflatable shape, at least one safety feature can be added, to ensure positioning and increase partial or permanent holding. For example at least one axle support, integral with the inflatable shape, which is crossed by an axle, integral with the solid shape of the wheel support frame, said axle is oriented towards the wheel so that the assembly and disassembly of the invention is only possible when the inflatable shape is deflated.

[0012] The engine(s), energy storage areas, brake(s) to operate the vehicle are in the wheels, said wheels also have turn signals and the cables connect all the wheels together.

[0013] The mudguard is an energy reserve mudguard and serves as a mudguard and energy reserve, it fits on all wheels of the vehicle; connections between the individual energy reserve mudguards allow to form a common energy reserve. The energy reserve mudguard can be doubled to increase the common reserve.

[0014] Part of the vehicle's envelope, consisting of two fabric walls, can change color. Light sources can be inside the two walls or outside against the walls or both.

[0015] Braking is achieved using the electric motor(s), it is an electrical system that uses regenerative braking coupled with current injection braking. A mechanical brake can be used to immobilize the vehicle when stopped and in the event of a power outage, said brake can be a current failure brake. Current injection braking can be replaced by regenerative braking and a heat sink for the generated energy to manage when the battery is full. Energy reserve management can also be added at four levels: empty, low, high, full with energy reduction or consumption actions.

[0016] Folding solar panels cover or make up parts of the vehicle's envelope or inflatable structure.

[0017] When all the solutions presented above are combined, the invention is a solar-powered, electric, foldable inflatable vehicle that is as light as possible and takes up the minimum amount of space when deflated. Benefits provided

[0018] Advantageously, the invention allows for reduced weight and energy consumption, low production costs, simple repairs and takes up less space for transport or storage.

[0019] The other great advantage of the invention is its modularity. As the inflatable floor is flat, it allows you to choose where to place the driver, passengers, the trunk, the bed, etc. And for the same floor, you can have several designs.

[0020] Another benefit of the invention is safety. Since there are one or more inflatable elements with pressure relief valves set to different pressures, the deformation of the vehicle during an impact can be controlled, reducing the consequences for the vehicle and for the people inside.

[0021] When the controls are a handle with management buttons, it allows it to be even lighter, to take up less space, it is easy to install and above all the vehicle can then be used for people with or without disabilities.

[0022] Another benefit of the invention is that the wheel support frame allows a wheel to be fixed simply by the inflation pressure of the inflatable shape itself. Furthermore, with this solution, wheels can be fixed on shapes of different widths. Moreover, if the pressure of the inflatable shape to be transported is high, it is possible to have better support and increase the rolling speed.

[0023] Another benefit of the invention is the ability to replace your vehicle at a lower cost. By keeping the same wheels and wheel supports, you can install a wider floor or a different upper shape. This will make certain parts last longer and also make them easier to recycle; this reduces the vehicle's environmental impact while lowering the cost of replacing your vehicle.

[0024] The invention also allows you to configure your vehicle by adding energy reserve mudguards, which can be mounted on all wheels, thus increasing the vehicle's range.

[0025] In addition, the invention allows the color of the vehicle to be changed at the level of the vehicle's envelope, which can be inflatable.

[0026] In terms of safety, the invention makes it possible to eliminate the influence of atmospheric conditions by eliminating mechanical contact with the brakes, while also eliminating mechanical braking noise.

[0027] And finally, the invention is partly autonomous thanks to solar panels. Brief description of the drawings
