Definitions

  • the invention relates to a variable electric vehicle with a transport function according to the preamble of claim 1 and a method for changing its state.
  • the invention relates to such a variable electric vehicle with transport function and a method for changing its state.
  • a basic state can be selected in which a loading area and behind it a space for one person are provided.
  • the basic state is called the "long state", in which the vehicle serves as a load scooter.
  • the vehicle can be transferred to a further state, which is a shortened state compared to the basic state, and in which a function is omitted. This state is called the "short state”.
  • a suitcase kick scooter is disclosed in the prior art at www.micro-mobility.com/de/commun/micro- luggage.
  • it is a conventional wheeled suitcase with a handle and two wheels, which can be pulled but also pushed.
  • a fold-down footboard with a twin wheel is arranged on one of the two large areas of the case. When the footboard is folded down, the twin wheel is on the ground and therefore active. The long state is thus selected, in which the person concerned can stand on the footboard of the suitcase pedal scooter thus formed and push it.
  • a vehicle is also disclosed on the Internet at http://nimblescooters.com/xl/, which in the long state serves as a load kick scooter with charging box and running board, and in the short state serves as a handcart which is pushed and in principle a shopping trolley is similar.
  • the vehicle or handcart was in short to four wheels, of which the two wheels of the rear axle are rigid on the frame, while the two wheels of the front axle are freely pivotable.
  • a footboard with an additional wheel can optionally be folded down, which means that it is in a long condition. Then the person concerned can stand on the footboard of the load pedal scooter thus formed and push it on.
  • the vehicle in the long state can also be referred to as a train, the steering of which rela tively relative to the loading box by angling the footboard and thus by angling the wheel of the rear axle to the wheels on the central axle.
  • the swiveling wheels of the front axle must adjust themselves to the selected curve radius (by a swiveling movement) with each steering movement. If the steering is turned while the train is still, the two wheels of the front axle must drive in an arc while the vehicle is still, which makes it difficult to turn.
  • the state change due to the manual folding of the footboard is complex.
  • the object of the present invention is to provide increased driving stability of the electric vehicle in both states.
  • the electric vehicle should remain upright in both states, even if it is switched off.
  • a long and a short state can be set in the claimed electric vehicle.
  • a loading area for example with a loading area or a loading box, and a footboard (viewed in the direction of travel) arranged behind it are provided for one person.
  • the electric vehicle thus forms a cargo scooter in its long state.
  • the short state exactly two active axes are provided. According to the invention, exactly two active axes are provided even in the long state.
  • the two active axles are physical arrangements with one or two wheels which are spaced apart from one another in the direction of travel and which actively support the electric vehicle.
  • the electric vehicle is adjusted from the short to the long state, there is no third active axle, but the wheelbase of the electric vehicle is enlarged. This does not convert the electric vehicle into a train.
  • This has advantages in terms of handling, e.g. when steering and especially when turning the steering at a standstill.
  • the electric vehicle according to the invention can e.g. be turned much easier.
  • the electric vehicle always has exactly one active front axle and always exactly one active rear axle.
  • the active front axle of the electric vehicle remains physically the same in the long and short state of the electric vehicle.
  • the active rear axle of the electric vehicle can be physically different in the long and in the short state.
  • the active rear axle of the electric vehicle in the short state can have only one support wheel or two support wheels.
  • “Active” axle is to be understood to mean that its wheel or wheels are / are on the ground and thus support the electric vehicle.
  • “Deactivated” axle is to be understood to mean that its wheel or wheels are / are lifted off the ground and therefore do not support the electric vehicle.
  • the long state can also be referred to as the basic state with all the functions of the electric vehicle, while in the short state the running board or the loading area are deactivated.
  • the two states can also be referred to as operating modes or frame lengths.
  • the front axle and the rear axle were - as usual - designated with a view to a main driving direction of the electric vehicle, in which e.g. the loading area is in front of the running board.
  • the direction of travel can also be reversed for a reverse drive of the electric vehicle.
  • the rear axle is temporarily in front of the front axle in the direction of travel.
  • Such a reverse drive can e.g. take place when the electric vehicle is guided behind a walking operator with the running board deactivated.
  • one of the two active axles or both active axles has two wheels, that is to say a left and a right wheel. These are at a distance from one another which is greater than a width of the running board or greater than a thickness of a handlebar tube of a steering system or greater than a length of a handlebar rod of the steering or wider than 20cm.
  • the thickness of the handlebar tube and the length of the handlebar are directed transversely to the longitudinal axis, that is, in the width direction of the electric vehicle.
  • a seat can be provided for the person.
  • the electric vehicle according to the invention can be started very comfortably and safely by the person first preferably stepping on the footboard with both feet or even sitting on the seat and then starting the electric drive without time pressure and balance problems. Slow driving is also possible without tipping over. Further advantageous embodiments of the invention are described in the dependent Pa claims.
  • the two wheels spaced apart according to the invention are at a distance from one another, which is also greater than a width of the loading area, there is an increased driving stability of the electric vehicle in both states.
  • the electric vehicle has four wheels, which can be arranged in a rectangle when viewed from above. This reduces the rolling resistance in the long state compared to the five wheels of the prior art. In addition, the driving properties are improved on uneven floors.
  • the active axle or the active axles with two wheels preferably has two lateral cross tubes or a continuous cross tube, on the outer end portions of which a wheel is arranged in each case.
  • the two wheels of one axle can e.g. like twin wheels arranged close together.
  • One of the two active axles can have a preferably central wheel.
  • the active front axle has the two wheels spaced apart according to the invention, between which - at least in the long state - the loading area is arranged, while the active rear axle has a wheel.
  • the electric vehicle is stable and remains upright when parked.
  • the rolling resistance to four wheels (short state) or five wheels (long state) of the prior art is reduced to three wheels in both states.
  • the steering of the electric vehicle preferably has the handlebar tube, which extends upwards or diagonally upwards, and which is rotatable about its steering axis.
  • the handlebar tube is advantageously arranged between the loading area and the running board.
  • the handlebar is advantageously arranged approximately transversely at the upper end section of the handlebar tube. If the handlebar tube and the footboard and the rear axle can be pivoted or rotated with their wheel about a longitudinal axis of the electric vehicle, a cornering position is also possible for the person in the three-wheeled vehicle.
  • the front axle remains flat or parallel to the ground.
  • the pivotability or rotatability is given in both states of the electric vehicle.
  • Either the entire front axle can be pivoted about a vertical axis of the electric vehicle via the steering, or the two wheels of the front axle can be pivoted about a vertical axis with respect to the front axle or with respect to a front frame part.
  • the front axle is preferably pivotable about a front frame part. In the first variant and the development with the cross tube, this is pivotable relative to the front frame part. In the second variant and in the development with the cross tube, the two wheels of the front axle are pivotable relative to the respective outer end portion of the cross tube.
  • the handlebar tube is preferably rotatable only in the long state of the electric vehicle and rotatably connected to the frame in the short state. Then the electric vehicle can be steered in the long state - preferably via its handlebar - by a moving operator, and in the short state it can be controlled by a walking operator via the handlebar tube - preferably via its handlebar.
  • either the wheels of the front axle can be swiveled freely passively or the at least one wheel of the rear axle can be swiveled passively freely. Even if for technical reasons a completely free swiveling is not always possible, this represents a preferred further development. Then the direction of travel can simply be changed and the at least one freely swiveling wheel swivels by 180 ° and adjusts itself passively according to the new direction of travel.
  • a battery for the electric drive can be arranged in the handlebar tube or on the side of the longitudinal axis of the vehicle on the front frame part or under the running board or in or on the transport box.
