    The present invention relates to a stroller with an electric motor drive.
    DE 10 2007 004 704 A1 shows a stroller with an electric drive. In this case, a drive unit is attached to the stroller, which has its own wheel. The drive unit together with the wheel is lowered to the ground for the electric drive.
    Further prior art is shown in DE 20 2007 010 454 U1. This document shows a stroller in which the electric drive is integrated directly into the axle of the pushchair.
    DE 20 2010 000 595 U1 shows a pushchair with wheel hub motor. Disclosure of the invention
    The pushchair according to the invention has the advantage that the drive module office the electric motor and the battery in a simple manner on the frame of the baby carriage can be mounted and dismounted. As a result, the relatively heavy drive module can be easily separated from the frame, whereby, for example, loading the stroller into the trunk or carrying it up stairs is much easier. In the drive module, no additional components, such as an additional wheel, are used. Rather, the drive module transmits the driving force to an already-existing wheel of the baby carriage. All of these benefits are achieved by means of a stroller comprising a frame and a plurality of wheels attached to the frame. In particular, three or four wheels are attached to the frame. The frame serves to receive a corresponding shell or seat in which a child can be transported. At least one of the wheels is connected to an axle. In particular, this is the rear axle of the baby carriage. More preferably, one wheel is located at each end of the axle. The wheels are correspondingly non-rotatably connected to the axle. A first power transmission wheel is mounted on the axle. The stroller further comprises a drive module. This drive module in turn comprises a second power transmission wheel, an electric motor driving the second power transmission wheel, and a battery supplying power to the electric motor. The battery is designed in particular as an accumulator. The drive module can be mounted on the frame and removed from the frame. In the assembled state, the two power transmission wheels for a positive or frictional power transmission from the drive module to the axle and thus to the at least one wheel. The battery, in particular an accumulator, is preferably removably attached to the drive module so that separate loading is possible.
    The dependent claims show preferred developments of the invention.
    It is preferably provided that the drive module can be mounted on the frame via a connection device. The connecting device is designed for tool-free operation. This allows the user of the stroller without the use of a tool mount the drive module on the frame and dismantle again. Due to the simple decrease of the drive module, the stroller can be transported without additional weight, ie without the drive module. Furthermore, if an electric drive is not desired, it is possible to use the baby carriage even without the heavy drive module.
    The connecting device comprises in particular a quick-release connection and / or a latching connection and / or a hooking connection and / or a wing nut and / or a thumbscrew. A quick-release connection is known, for example, from bicycle construction. There, the quick release connection is used to attach the rims to the frame. A latching connection usually has a latching nose and a latching projection. When mounting the drive module, the detent latches behind the latching projection.
    For example, by lifting the locking lug, this connection can be solved without tools. The hooking connection has at least one hook hooking to a counterpart. By means of wing nuts and / or wing screws, a tool-less operable screw connection between the drive module and the frame is possible.
    It is preferably provided that in the mounted state of the drive module, the two power transmission wheels touch. Thus, there are no intermediate elements, such as additional power transmission wheels or transmission belts. There is a direct power transmission from the second power transmission wheel to the first power transmission wheel.
    In particular, the two power transmission wheels are either both designed as gears or both as friction wheels.
    The drive module preferably comprises power electronics. The power electronics are located in the live line between the battery and the electric motor. Particularly preferably, a control device is provided in the drive module. By means of the control unit, the electric motor can be controlled via the power electronics.
    Furthermore, the drive module preferably comprises a transmission. The transmission translates between the electric motor and the second power transmission wheel.
    Furthermore, the drive module preferably comprises a sensor system. By means of this sensor system, for example, a pushing of the baby carriage can be detected and the electric motor can be switched on accordingly.
    Preferably, a data interface is provided between the drive module and the frame. This data interface serves to drive the electric motor and thus transmit the shifter request (to convey the desire of the user of the pushchair) to the electric motor.
    In particular, the data interface comprises a plug on the frame and a socket corresponding to the plug in the drive module. Alternatively, the socket can also be mounted on the frame and the plug on the drive module. When mounting the drive module to the frame, at the same time, the plug and socket snap into each other so that the data interface between the frame and the drive module is made.
    As an alternative to using the plug and the socket, wireless data transmission is provided between the frame and the drive module.
    The stroller preferably comprises at least one operating unit. This operating unit is mounted on the frame and / or the operating unit is implemented as software in a smartphone. The data transfer from the smartphone to the data interface is wireless.
    When using the control unit mounted on the frame, the data transmission in a first variant is wired to the data interface. From the data interface, the data transfer either via the plug and socket or wirelessly to the drive module. It is also preferred that the data interface is integrated directly into the frame mounted control panel. As a result, a wireless data transmission is possible directly from the operating unit to the drive module.
    The control unit allows the electric motor to be switched on and off. Thereby, the slider informs the drive module that it wants to start with the baby carriage. The operating unit is preferably designed so that it stops when it is released by the slide the stroller. According to preferred turning handle, e.g. Similar to a motorcycle throttle, the speed of the electric motor can be regulated. A preferred mode choice, e.g. Jogging, walking or braking triggers a corresponding control of the electric motor.
    For reasons of convenience, two control units for left and right-handers are preferably mounted. Alternatively, it is provided that the operating unit can be detached from the frame without tools and positioned at the desired position of the frame. The operating unit can be operated preferably with one hand.
    The operating unit implemented in the smartphone is in particular designed to record the energy consumption, to select the mode (for example, jogging,
    Walk, downhill), to record the route (navigation), and / or to diagnose any errors in the drive module.
    In addition to the combination of stroller and drive module to be claimed with the present invention, of course, the individual components, i.e. the stroller without drive module and the drive module as such with the features described.
