    ELECTRIC CHILDREN'S CAR
    The invention relates to a stroller with a frame, a reclining or seat insert and at least three wheels, wherein at least one of the wheels is drivable with at least a first electric drive unit.
    Electrically powered baby carriages have already become known. For example, DE 20 2010 009 628 U1 shows a stroller in which an electrically operated wheel hub motor is set up to drive at least one wheel. The manual effort to move the stroller is thereby reduced, thus increasing the ease of use is achieved. Such known baby carriages have a lying or seat insert which is anchored substantially rigidly in the stroller. A comfortable for children or children rocking or rocking the reclining or seat insert can therefore be achieved only by a rocking or rocking of the entire stroller, for which considerable effort has to be spent. On the one hand, this can lead to fatigue and tension in the muscles of operating persons, and on the other hand, it can significantly limit the time span in which the infant or the child is rocked. In addition, the rocking or rocking is generally achieved only by active intervention of the operator and their attention is directed to the execution of this activity.
    An object of the invention is therefore to provide a stroller, in which a simple rocking or rocking of the reclining or seat insert is possible without special effort of the person leading the car. This object is achieved in a stroller of the type mentioned in that at least a second electric drive unit connected to the recliner or seat insert and is adapted to move the reclining or seat insert from a first deflection position in at least a second deflection position. Thanks to the invention, a necessary for the at least one first electric drive unit power supply unit for feeding the at least one second electric drive unit can be used, whereby the rocking or rocking of the reclining or seat insert can be accomplished by means of a particularly simple technical structure. -2- P12531
    In an advantageous embodiment, it is provided that the lying or seat insert is connected to a rotating shaft mounted in the frame and is rotatable therewith, wherein the rotation of the rotary shaft is effected by means of the at least second electric drive unit connected thereto, and the first deflection position of a predetermined first position and the second deflection position corresponds to a predetermined second position of the rotary shaft. This is a particularly simple mechanical structure of a rocker or. swingable lying or seat insert given.
    In order to increase the rocking or rocking comfort in addition, it is provided to limit the scope of the rocking or rocking motion, in that the rotary shaft encloses an angle of maximum 60 ° when rotating from its first to its second position, and a third Position happened.
    In addition, it is provided in an advantageous embodiment that the rotary shaft can be fixed in the third position, which is located in any desired, definable rotational position between the first and second position. Thus, despite downward or upward travel of the stroller, if desired, a horizontal position of the reclining or seat insert can be realized. In addition, positions outside of the horizontal position can also be selected, giving additional possibilities for maximizing comfort.
    In order to counteract a tilting of the stroller, in an expedient embodiment, a frame attached to the sensing arm is provided with an end portion, wherein the end portion in an operating condition in which all wheels of the stroller contact a ground, at a defined distance above the ground and a rear wheel is located, wherein the end portion for detecting ground contact has a sensor or a connection to a sensor. As a result, the risk of tilting of the stroller can be detected prematurely and avoided for example by stopping the driven wheel.
    In an advisable variant, it may be provided that the stroller has a handle on which a user interface with operating elements for controlling or regulating the at least one first and the at least one second drive unit is arranged. This allows easy handling of the stroller.
    ZHoSAL -3- P12S31
    In order to combine the advantage of a mobile power supply of the electric drive unit with that of a non-tilting deep pram center of gravity, at least one power supply unit arranged in the lower fifth of the height of the stroller is provided in a further advantageous embodiment.
    It is advantageous if the power supply unit is designed to be rechargeable. A charge can be achieved in this case in a further embodiment, by a basket is attached to the lying or seat insert, which has a multi-segment hood, and at least one segment at least one photovoltaic module is arranged. To slow down driving with the stroller or, if desired, to apply a virtual rolling resistance to a wheel connected to the at least one electric drive unit, the at least one first electric drive unit is designed for braking operation in an expedient embodiment.
    In addition, the charging of the power supply unit can take place via conventional household sockets (for example 230V ~), on-board power outlets or the like. In a particular embodiment, it is also provided that the at least one first electric drive unit in the braking operation energy in the power supply unit fed back which the braking operation is realized particularly efficient.
    The invention is explained in more detail below with reference to an exemplary embodiment, which are illustrated in the figures. This shows
    1 is a side view of the stroller according to the invention,
    2 is a plan view of the stroller according to the invention without assembled basket,

    Fig. 4 is a plan view of the stroller according to the invention with mounted basket.
    The invention will be described in detail below with reference to FIGS. 1 to 4.
    Fig. 1 shows a side view of the stroller according to the invention. This has in the illustrated embodiment, two rear wheels 1 and a single front wheel 2. These
    ViOSAL ·
    are mounted on a frame 3 wherein the front wheel 2 is connected to an electric drive unit 4 on drive. The drive unit 4 can be via any electric motor, such as a brushless IX! Engine as well as have a transmission. It is envisaged that the drive unit 4 does not hinder the free running of the front wheel 2 in an off state by this is either decoupled or without resistance follows the rotational movement of the front wheel 2. The embodiment as a front-wheel drive is to be considered as an example. The stated properties apply unless otherwise stated in the same way for alternative embodiments, such as a rear-wheel drive stroller.
    The frame 3 shows a substantially triangular geometry in side view, with a leg connecting the front wheel 2 to the rear wheel 1 running substantially parallel to the floor 5 on which the stroller is traveling, and the second leg facing away from the front wheel 2 into a straight line Extension thereof projects beyond the substantially triangular geometry, and at a position substantially above the level of the fifth, at the end of which, at the same time, a pushing handle 6 with a handle 7, on which a user interface 8 with operating elements 9 (FIG. 2) is arranged. The two rear wheels 1 are connected to a wheel axle 10. The hidden in the side view rear wheel 1 is connected in a symmetrical manner with legs so that in a plan view (Fig. 2) along a center line ML1 symmetrical structure of the frame 3 can be seen. Fig. 1 shows at the intersection of the two legs which are not arranged parallel to the bottom 5, a holding plate 11 which is fixed by means of a first connecting element 12 stanr to the frame 3. The first connecting element 12 can be realized for example by a bolt or a screw-nut connection. The holding plate 11 is inclined substantially normal to the above-mentioned to the bottom 5 parallel legs and points in the direction of an above-mounted reclining or Sitzin-set 13. The holding plate 11 and the first connecting element 12 will be considered from now on as part of the frame 3. The holding plate 11 has in the upper end region of a bearing 14 which is adapted to receive a Eirehwelle 15. The lying or seat insert 13 is rigidly connected to the rotary shaft 15, whereby the reclining or seat insert 13 can be rotated as it were with the rotary shaft 15. The arrangement of the holding plate 11 and the rotary shaft 15 can be modified in various manner understandable to the skilled person. It may be mentioned by way of example that the rotary shaft 15 can certainly be arranged directly on the point of intersection of the limbs called PI2531 4.1 -5, and from there, the holding plate 11 can be connected to the reclining or seat insert 13. Likewise, the waiver of the holding plate 11 is conceivable.
    In the embodiment shown, a second electric drive unit 16 can be seen, which is located in close proximity to the rotary shaft 15. The drive shaft 27 (FIG. 2) of the second drive unit 16 is connected directly to the rotary shaft 15 in the exemplary embodiment shown. In contrast to the first drive unit 4, the drive shaft 27 of the second drive unit 16 is fixed against rotation, for example by the provision of a self-locking drive or a locking device, whereby the attached to the rotary shaft 15 reclining or seat insert 13 stably and securely remains in a fixed position ,
    The lying or seat insert 13 is part of a basket 21, which has a segmented hood 20, at the segments 19 each have a photovoltaic module 18 is arranged. The basket 21 is connected via the reclining or seat insert 13 with the rotary shaft 15. This connection may be a permanent connection (e.g., a bond), as well as a releasable threaded connection, or, advantageously, a releasable quick release, which allows the basket 21 to be disassembled quickly. This is in an embodiment of particular advantage in which the stroller is hinged by the frame 3 has corresponding joints or guides, and thus requires less storage space in the folded state and thus easier to transport. The segments 19 are rotatable about a second connecting element 17. The second connecting element 17 may be, for example, a screw connection or a rotatably mounted bolt connection. The number of arranged on the segments 19 photovoltaic modules 18 is limited only by the surface of the segments 19 and may differ from the number shown in any way. In addition, the hood 20 can be carried out together with the segments 19 of the basket 21 detachable, for example by a quick release is provided for this purpose.
    An angle ü determines the position of the rotary shaft 15, wherein the angle D has the value 0 ° in a position in which the reclining or seat insert 13 is aligned substantially parallel to the contacted by all wheels 1 and 2 bottom 5. Angle D may, in a preferred embodiment of the invention, assume angles of -30 ° to + 30 °, [10 2012/50199
    For example, the first deflection position corresponds to an angle of -30 ° and the second deflection position corresponds to a position of + 30 °. The limitation of the swept angle range to 60 ° is used to avoid Überufemden movements and thus allows a safe stay of an infant or child in the basket 21. In this case, the lying or seat insert 13 can remain in any third position, which is in an angular range between -30 ° and + 30 °.
    Furthermore, FIG. 1 shows a power supply unit 22 which is designed to be rechargeable in an advantageous embodiment. The power supply unit 22 is preferably arranged in the lower fifth of the height of the pushchair in order to locate its center of gravity as low as possible so that the risk of tipping is reduced to a minimum. For this purpose, moreover, a feeler arm 23 is arranged on the frame 3, which has an end portion which in an operating condition in which all wheels 1 and 2 of the pushchair contact the floor 5, at a defined distance above the bottom 5 and behind a rear wheel 1 and the ground contact detection end portion has a sensor 24. Possible distances are exemplified by 50%, 40%, 30%, 20% or 10% of the rear wheel height. Alternatively, the sensor 24 may be arranged at any point of the baby carriage and have a connection to the Fühlarm 23 and the Endabschrdtt, the Fühlarm 23 may be stored for example drehbaT and the sensor 24 detects changes in the angular position of the Fühlarms 23. Also, the end portion of the sensing arm 23 may be equipped with a further wheel that permanently contacts the bottom 5 and, for example, reacts to relative changes in position relative to the frame 3.
    The power supply unit 22 is preferably located in a watertight, protective housing, in which also a control / regulating unit 25 is accommodated, which converts the input variables generated by the user interface 9 into corresponding output variables in order to control or supply the electric drive units 4 and 16 as desired regulate. Depending on requirements, either a control or a control unit 25 may be provided here.
    Fig. 2 shows a plan view of the stroller according to the invention according to Fig. 1 without a basket. The frame is constructed symmetrically along the center line ML1, whereby on the one hand
    Flo 0.2012 / 5Ö1Ö9 a simple production and on the other hand in a simple way a balanced, good-natured performance of the stroller can be realized. A lever 26 is attached to the handlebar 6, which serves for the stepless determination of the extent of the driving support and the speed of travel of the baby carriage.
    In Fig. 3 is a front view of the rotary shaft 15 of the stroller according to the invention can be seen. The lying or seat insert 13 is rigidly connected therein by means of two screw connections with the rotary shaft 15. The second electric drive unit 16 is disposed therein at one end of the rotary shaft 15, wherein the second drive unit 16 has a drive shaft 27 which projects into a recess within the rotary shaft 15 and is rotatably connected, for example via a toothing with the same. The axes of the drive shaft 27 and the rotary shaft 15 are identical. The skilled person understood alternative embodiments for transmitting the drive torque of the second electric drive unit 16 to the rotary shaft 15 are also suitable for this purpose, the rotary shaft 15 is received by a bearing 14 in the holding plate 11, to which in turn the second electric drive unit 16 is fixed
    FIG. 4 shows a top view of the baby carriage with the basket 21 mounted thereon. This clearly shows the arrangement of the photovoltaic modules 18 which are attached to the individual segments 19 and form a hood 20 with them. The photovoltaic modules 18 extend substantially along the entire width of the segments 19.
    The operation of the invention will be further discussed below by way of example.
    Experience has shown that a gentle movement of an infant or child can have a calming effect on them. This gentle movement is often accomplished by gently rocking or rocking the infant or child, and is generally performed manually by a person familiar to the infant or child. If the infant or child as mentioned above is in the basket 21 of a baby carriage, it requires in conventional strollers with electric driving support of a considerable expenditure of force by a person operating to make the rocking or rocking motion. In order to eliminate the disadvantages mentioned at the outset, it is therefore provided that the rocking or rocking motion is automatically performed by at least one second electric drive unit 16, in that it makes a mechanical connection with the rotary drive.
    P12531 ^ 01012/50199 -8-wave 15 which is received in the bearing 14, and thus rotates the rotary shaft 15 together with the basket 21 fixed thereon in different positions. Alternatively, the at least one second drive unit 16 can be connected via a crankshaft or also directly to any mechanical oscillating system in order to carry out various rocking or rocking movements. The deflection of the rocking or rocking motion can be determined by the user by entering corresponding parameters by means of operating elements 9 arranged on the user interface 8 and the control / regulation unit 25 applying the corresponding output variables to the at least one second drive unit 4. In addition, its movement speed can be set in the same manner. The control or regulation is infinitely variable.
    Furthermore, a driving resistance can be generated by the first electric drive unit 4. In this case, the first electric drive unit 4 can be put into a generator mode, in which energy is fed back into the energy supply unit 22. This can prevent unwanted acceleration of the baby carriage, for example, when driving downhill inclined floors. In addition, a specific driving resistance may well be desirable even if e.g. in the course of sporting activity of the stroller, possibly when jogging, pushed by a user, and this selects a corresponding driving resistance to increase the intensity of training.
    Both the first and the second electric drive unit 4 and 16 are only applied to output variables when one of the controls 9, usually a switch, is in an activation position. For example, if the switch is outside the activation position, then the rolling resistance of the stroller is not significantly different from that of a conventional stroller without electric drive unit The basket 21 dwells rigidly in the last specified position.
