Definitions

  • the invention relates to a small electric vehicle, in particular an electric scooter, with a steerable front wheel, a rear wheel, a frame that has a steering head for the front wheel, and a carrier with a running board.
  • Small electric vehicles such as electric kick scooters or e-scooters are known. They have an electric drive and are often used as a vehicle for short distances such as "the last mile” or "the last kilometer”.
  • small electric vehicles are motor vehicles with an electric drive and a design-related maximum speed of no less than 6 km/h and no more than 20 km/h, which have the following features, among others:
  • a rated continuous power of not more than 500 watts, or not more than 1400 watts if at least 60 percent of the power is used for self-balancing,
  • Some small electric vehicles have a folding mechanism, by means of which the small electric vehicle can be folded up compactly when not in use, for example for transport in public transport or for space-saving stowage.
  • the object of the invention is to provide a small electric vehicle with a folding mechanism that can be folded up in a particularly compact manner.
  • a small electric vehicle with a folding mechanism that can be folded up in a particularly compact manner.
  • the carrier has a rear carrier section, which is connected to the rear wheel, and a front carrier section, which is connected to the frame and a mount for the rear wheel.
  • the wheel folding mechanism has a first joint with a first pivot axis, by means of which the small electric vehicle can be adjusted from an unfolded position into a folded position.
  • the front support section is connected to the rear support section by means of the first joint.
  • the rear wheel is here in the unfolded position in an outer position in which the rear wheel is arranged outside the receptacle, and in the folded position in an inner position in which the rear wheel is arranged at least partially inside the receptacle.
  • the rear wheel In the inside position, the rear wheel is closer to the front wheel than in the outside position.
  • the distance between the front wheel and the rear wheel in the folded position is only 70% to 75% of the distance between the front wheel and the rear wheel in the unfolded position.
  • the wheel folding mechanism has a second joint with a second pivot axis.
  • the running board is connected to the front carrier section by means of the second joint.
  • the footboard can be adjusted by means of the second joint between a closed position, in which the footboard provides a stepping surface and at least partially covers and/or blocks the receptacle, and an open position, in which the footboard releases the receptacle for receiving the rear wheel.
  • the footboard is in the closed position in the unfolded position of the small electric vehicle and in the open position in the folded position of the small electric vehicle.
  • the space in the unfolded position is provided as a tread, used to provide space for the rear wheel in the folded position.
  • the small electric vehicle can therefore be folded up in a particularly compact manner.
  • the rear wheel can be pivoted about the first pivot axis by means of the first joint over a path which, in a vertical driving position of the small electric vehicle, points below, i.e. between the carrier and the roadway, in order to adjust the rear wheel from the outer position to the inner position .
  • the micro electric vehicle can have a stop which is designed in such a way that the rear wheel cannot be pivoted in the outer position opposite to the pivoting path, i.e. upwards away from the roadway.
  • the rear support section encloses a first angle with respect to the front support section in the folded position and a second angle in the unfolded position.
  • the difference between the first and second angle is between 150° and 210°, in particular 180°.
  • the rear wheel can be mounted so as to be rotatable about an axis of rotation which runs parallel to the first pivot axis.
  • the rear wheel In the inner position, the rear wheel is mounted so that it can rotate freely about the axis of rotation and protrudes downwards beyond the carrier when the small electric vehicle is in a vertical sliding position.
  • the micro electric vehicle can be pushed in a vertical folded position over the front wheel and rear wheel, both of which roll over the ground. In this state, both the front wheel and the rear wheel remain freely rotatable, so that the light electric vehicle can be pushed and does not have to be carried.
  • the small electric vehicle can have a drive and be designed in such a way that the small electric vehicle can be driven in the folded position by means of the drive via the front wheel.
  • electric pushing assistance can be provided, preferably via a hub motor in the front wheel, so that the small electric vehicle can be moved, for example, over ramps with electric assistance at up to 6 km/h.
  • the micro electric vehicle has a handlebar unit and a handlebar folding mechanism, which has a third joint with a third pivot axis.
  • the link unit can be pivoted between a driving position and a transport position about the third pivot axis by means of the third joint.
  • the third pivot axis preferably runs through a steering head bearing of the steering head, as a result of which the small electric vehicle can be folded up in a particularly space-saving manner.
  • the steering unit can be shaped in such a way that in a transport position of the small electric vehicle, in which the rear wheel is in the inner position and the steering unit is in the transport position, a straight line that runs parallel to the first pivot axis intersects the rear wheel and the steering unit.
  • the link unit is designed in such a way that in the transport position it partially runs next to the rear wheel, for example by the link unit being bent accordingly or having a recess for the rear wheel.
  • FIG. 4 in a schematic side view of the electric vehicle from Figure 1 in a transport position.
  • FIG. 1 shows a small electric vehicle 10 in a ready-to-drive position and in an upright position in the vertical direction V.
  • the micro electric vehicle 10 is an electric kick scooter, which is also referred to as an e-scooter.
  • the ElektroklemstGerman 10 has a frame 12 with a steering head 14, a steering unit 16 and a front wheel 18, which is rotatably mounted in the steering head 14 by means of the steering unit 16 and is adjustable via the steering unit 16 between different steering positions.
  • the small electric vehicle 10 has a carrier 20, which has a front carrier section 22 and a rear carrier section 24, and a rear wheel 26, which is rotatably mounted about an axis of rotation D on the rear carrier section 24.
  • the carrier 20 in this case has a footboard 28 and a receptacle 30 which is covered by the footboard 28 in the ready-to-drive position.
  • the small electric vehicle 10 has an electric hub motor 32 in the front wheel 18 and an electric drive unit 34 which is coupled to the hub motor 32 and is attached to the frame 12 and can be controlled or actuated via the steering unit 16 .
  • the small electric vehicle 10 also has a wheel folding mechanism 36, by means of which the small electric vehicle 10 can be adjusted between an unfolded position, which includes the ready-to-drive position (see Figure 1) of the small electric vehicle 10, and a folded position, which is a sliding position (see Figures 2 and 3 ) and a transport position (see Figure 4) of the small electric vehicle 10 includes.
  • the wheel folding mechanism 36 has a first joint 38 with a first pivot axis R, by means of which the front support section 22 is pivotably connected to the rear support section 24 about the first pivot axis R, and a second joint 40 (see Figure 3) with a second pivot axis T , by means of which the footboard 28 is pivotally connected to the front support section 22 about the second pivot axis T.
  • the footboard 28 can be adjusted by means of the second joint 40 between a closed position (see Figure 1), in which the footboard 28 is aligned essentially horizontally and provides a stepping surface, and an open position (see Figures 2 to 4), in which aligns the running board 28 essentially vertically and releases the receptacle 30, ie no longer covers it.
  • the footboard 28 is designed in one piece.
  • the running board 28 can be designed in several parts, e.g. halved in the longitudinal direction. In this case, a number of articulations are correspondingly provided in order to move the footboard parts covering the housing 30 between the closed position and the open position.
  • the rear wheel 26 can be adjusted by means of the first joint 38 between an outer position (see Figure 1), in which the rear wheel 26 is arranged outside the receptacle 30, and an inner position (see Figures 2 to 4), in which the rear wheel 26 is in the Recording 30 is recorded.
  • the footboard 28 is first moved from the closed position to the open position, i.e. folded up to the side, and then the rear wheel 26 along a pivot path U from the outboard position in the recording 30 pivoted and thus adjusted to the inner position.
  • the first pivot axis R is arranged directly in front of the rear wheel 26, as a result of which the light electric vehicle 10 is particularly compact in its longitudinal extension.
  • the rear wheel 26 is thereby pivoted along the pivot path U by an angle which corresponds to the angle a (see FIG. 4) of 25° plus 180°, ie by a total of 205°.
  • the angular difference between the outer position and the inner position can be of any size.
  • the angle difference is preferably between 150° and 210°, in particular 180°.
  • the pivot path U in which the rear wheel 26 pivots from the outer position to the inner position, initially runs downwards in the direction of the roadway or the ground.
  • the first pivot axis R runs parallel to the axis of rotation D, as a result of which the rear wheel 26 is aligned in the primary direction of travel of the small electric vehicle 10 in all pivot positions. As a result, the rear wheel 26 also rolls optimally in the inner position, so that the micro electric vehicle 10 can be pushed or driven in the primary direction of travel with little resistance in the pushing position.
  • the light electric vehicle 10 is designed such that the rear wheel 26 protrudes downwards over the carrier 20 counter to the vertical direction V in the inner position, so that the light electric vehicle 10 is in an upright position on the front wheel 18 and the rear wheel 26.
  • An outer stop 42 is also attached to the carrier 20, which prevents the rear wheel 26 from being able to pivot further than the pivot path II, i.e. upwards, in the outer position.
  • an inner stop 44 is attached to the carrier 20, which prevents the rear wheel 26 from being able to swivel further than the swivel path II, i.e. upwards, in the inner position.
  • the rear wheel 26 is held in a defined position while driving in the outer position and in the sliding position in the inner position due to the acting weight of the micro electric vehicle 10 itself or a driver.
  • the wheel folding mechanism 36 has a locking mechanism 46 by means of which the wheel folding mechanism 36 can be locked and released.
  • the locking mechanism 46 is a quick release here.
  • the wheel folding mechanism 36 can have one or more magnets, for example on the outer and/or inner stop 42, 44, which hold the rear wheel 26 in the outer position or inner position.
  • the light electric vehicle 10 has a mudguard 48 for the rear wheel 26 which is adjustably attached to the front support section 22 and can therefore be adjusted in its orientation to the outer position and the inner position of the rear wheel 26 .
  • the mudguard 48 can be coupled to the locking mechanism 46 in such a way that the release or locking of the wheel folding mechanism 36 at the same time the fender 48 is released or fixed in its orientation.
  • the small electric vehicle 10 In order to move the small electric vehicle 10 from the sliding position (see FIGS. 2 and 3) into the transport position (see FIG. 4), the small electric vehicle 10 has a handlebar folding mechanism 50 .
  • the handlebar folding mechanism 50 has a third joint 52 with a third pivot axis L, by means of which the handlebar unit 16 can be moved between a driving position (see Figures 1 to 3), in which the handlebar unit 16 is oriented substantially vertically, and for steering the light electric vehicle 10 in the ready-to-drive position of the small electric vehicle 10 is ready, and a transport position (see Figure 4) can be pivoted about the third pivot axis L, in which the steering unit 16 is oriented essentially horizontally in the transport position of the small electric vehicle 10.
