Definitions

  • the present invention relates to a drive module for a vehicle.
  • An example of a vehicle with an optional drive module is a wheelchair.
  • Most wheelchairs are purely mechanical, but there are also electric wheelchairs that have a built-in motor.
  • a third option is external drive modules for wheelchairs, which are also mounted on rollers and can either be held by the user or be detachably connected to the wheelchair. In these cases, the wheelchair including the driver is usually pulled and the drive module is located in front of the wheelchair.
  • strollers Another type of vehicle known from the prior art are strollers. These are usually delivered purely mechanically and are pushed by those accompanying the children. However, there are some models known that have an integrated motor. However, these were only developed as exhibition pieces or as experimental models and are not used in practice.
  • More well-known in strollers are transport modules for larger children, usually referred to as buggy boards, which can be connected to the stroller and which ride on their own wheels. Older siblings can stand on a buggy board or, in certain versions, sit down and be pushed along by the accompanying person.
  • the object of the present invention is to provide a connectable drive module for a vehicle that both drives the vehicle itself and at the same time enables people to be able to stand or sit on it.
  • a drive module with a seating or standing surface for connection to a vehicle the drive module being detachably connected to the vehicle and being able to be moved between a drive position and a rest position along a suspension, the drive module being in the Rest position under a lying, sitting or standing surface of the vehicle and in the drive position is located under, partially behind, or behind the lying, sitting or standing surface of the vehicle.
  • the invention is based on the surprising finding that a drive module with a seating or standing surface encompassed by it can be connected to a vehicle so that it is driven by the drive module.
  • the drive module is moved in a rest position under the lying, sitting or standing surface of the vehicle, so that the drive module does not hinder a user. Because the drive module is arranged under the lying, sitting or standing surface of the vehicle, it is virtually invisible and does not affect the aesthetics of the stroller. Furthermore, handling is not affected because the drive module is not in the way when the vehicle is moving.
  • the drive module can be located under the vehicle in a drive position or a rest position.
  • a rest position means that no active force is exerted by the drive module on the wheels of the drive module.
  • a non-driven vehicle it is possible for a non-driven vehicle to be coupled to an active drive module, with a seat or standing surface being able to be extended or retracted as required.
  • the sleep mode in which the drive module is in the rest position and does not provide any additional drive power.
  • a support mode in which the drive module uses sensors in the wheels to detect the direction in which the user is moving the vehicle and supports the movement with an intensity-adjustable drive force and a driving mode in which the user moves the vehicle without any own force, including via the drive module and selects speed and direction on a control module.
  • the drive module is in the rest position under the vehicle and raised and in the drive position under, partially behind or behind the vehicle and lowered.
  • the drive module By raising the drive module, it is achieved that it no longer restricts the mobility of the coupled vehicle to any extent or at all. It can be particularly advantageous that in the raised rest position the wheels of the drive module no longer touch the ground, so that the vehicle can be moved by the drive module without restrictions.
  • the drive module itself has at least one accumulator and a drive wheel, which is in operative connection with an electric motor, and wherein the electric motor is electrically connected to the accumulator, and wherein the drive wheel is in the Drive position is in contact with the ground.
  • the standing or sitting surface of the drive module is partially behind or behind the vehicle.
  • This can be used, for example, to transport one person or two or more people.
  • the angle and the distance of the handles for pushing vehicles is individual, so that optimal operability of the vehicle is always guaranteed by an adapted method of the drive module.
  • the suspension of the drive module is connected to a rear axle of the vehicle or a covering of the rear axle of the vehicle, a suspension of the Rear axle of the vehicle and / or a frame element of the vehicle is connected.
  • Sitting or standing positions can also be provided for one, two or more people.
  • the suspension is detachably connected to the vehicle, in particular at a position centrally above or on the rear axle, on side struts in the area of the rear axle and/or at two points on the rear axle.
  • the drive module is connected to the vehicle in the rest position by means of a fastening element, so that the drive module is raised and in particular the drive wheel or wheels do not touch the ground.
  • a raised drive module enables the vehicle to be moved as if no drive module were coupled. Since the drive module is in the rest position under the vehicle, and in particular is raised, the user does not notice it.
  • the fastening element is a magnet, a snap-in system, a hooking system, a Velcro fastener, a bayonet fastener, a push-button system and/or a clamping system.
  • a particularly advantageous fastening element is a magnet that reliably enables both the drive module and the vehicle to be connected and released in order to fix them in the raised position.
  • fastening elements in the form of Velcro fasteners or clamping systems also make sense to use, or in the case of particularly secure fastenings of hooking systems or bayonet fasteners.
  • the fastening element is arranged on the front end of the drive module and/or on or in the region of the front end of the vehicle, preferably above a front axle of the vehicle and/or the vehicle frame.
  • fastening element is arranged at the front end of the drive module and/or at or in the region of the front end of the vehicle, since the drive module is located in the rest position under the coupled vehicle.
  • an arrangement of the fastening module at the front end of the drive module and/or at the front end of the vehicle means that the drive module can form a standing or sitting surface approximately the length of the vehicle.
  • the drive module can use a large travel range when fully retracted and extended along a perpendicular to the rear axle.
  • At least one guide rail is included, along which the drive module can be moved from a sitting or standing position to the rest position and back.
  • the drive module is lowered and raised under, partially behind or behind the vehicle into the drive position by means of a spring element, a magnet, compressed air, its own weight and/or an electric motor. It has proven to be particularly advantageous if the drive module is attached to the vehicle on or in the area of the rear axle.
  • the rail system according to the invention with a guide rail has proven successful for moving the drive module relative to the vehicle.
  • a control module is included, designed and set up to control the speed and drive direction of the drive council, to adjust the drive module between the drive position and the rest position and/or to select and activate/deactivate control programs .
  • control module can be flexibly arranged by means of a wireless transmission module and includes an accumulator for supplying energy to the components included.
  • Such a control module can be arranged in particular on a handlebar of a vehicle.
  • the control module can have mechanical buttons and switches and/or digital control options.
  • a coupling with mobile phones can also be provided, which is implemented via wireless communication, for example via Bluetooth or WLAN.
  • a first brake is included, which is controlled by the control module and/or a second brake, which can be triggered mechanically on the drive module.
  • a mechanical brake is included, which is designed, for example, in the form of a foot brake. This can be used exclusively or alternatively and in combination with an electric brake or a brake that can be controlled via the control module.
  • the foot brake according to the invention can be arranged on one or both sides, in particular at the side ends of the drive device, and can be moved downwards by applying pressure so that it rests on the drive wheels and acts on them for braking.
  • the invention also provides a method for operating a drive module according to one of the preceding claims, comprising the following steps, in particular in this order: a) connecting the drive module to a vehicle b) controlling the drive module to adjust a speed and drive direction of the drive wheel , for selecting the position of the drive module between the drive position and the rest position and/or for selecting a control program, in particular for selecting and parameterizing a driving or support mode.
  • control program includes a sleep mode in which the drive module moves the vehicle back and forth a defined path at regular, adjustable intervals.
  • Such a sleep mode has the particular advantage that, for example, a drive module coupled to a stroller can move the stroller back and forth in a defined area, so that a child falls asleep without the accompanying persons having to actively move the stroller.
  • the invention provides a use of a drive module according to the invention in connection with a stroller.
  • a drive module according to the invention is therefore based on the surprising finding that it is possible to provide a drive for a vehicle on which one or more people can sit or stand at the same time, without the drive module itself being disruptive.
  • the rest position according to the invention makes it possible to use the coupled vehicle without a user experiencing disadvantages due to the coupling to the drive module. Rather, that is Drive module is stowed virtually “invisibly” under the vehicle.
  • the optional control module which interacts with the drive module in a wired or wireless manner, for example, allows the user to select different modes and control the drive module.
  • this includes the actual driving and braking, i.e. selecting different drive speeds and directions, as well as moving the seat or footprint of the drive module relative to the coupled vehicle.
  • the seat or footprint can in particular be moved in such a way that it fits the geometry of the vehicle and still allows people to be transported. You can also set whether one or more people can fit on the seat or surface.
  • the drive module enables maximum variability.
  • the drive module is optionally raised so that the drive wheels do not rest on the ground.
  • a drive module according to the invention can advantageously be coupled with strollers, wheelchairs but also other vehicles such as workshop trolleys.
  • the drive module In one mode, the drive module is in a rest position and does not actively support the movement of the vehicle. In a second mode, the drive module supports the Locomotion in which it applies additive force when the user detects movement of the vehicle and also exerts force in the direction in which the user moves the vehicle. In a third mode, the drive module can move the vehicle independently and the user selects speed and direction.
  • the fourth mode is the described sleep mode for strollers, in which the drive module moves a stroller back and forth.
  • a mechanical, preferably foot brake is also provided, which can be operated by the user independently of the control module and which can completely lock the wheels of the drive module.
