Description

Technical Field Background Technology

[0002] Strollers in general, but also strollers with auxiliary drive, have been known for many years, especially by DE 1817722 U. Furthermore, various possibilities for controlling the auxiliary drive are known from the prior art. For example, the auxiliary drive can be controlled by sensors in the stroller push rod section or by a manual control device, such as a thumb throttle.

[0003] For example, a multi-person stroller with auxiliary drive is known from EP 2332806 A2, in which a thumb throttle is proposed for controlling the auxiliary drive. A stroller with a thumb throttle as a control device for auxiliary drive is also known from US 8033348 B1. A problem with using known manual control devices (e.g., thumb throttles) is that these devices can only operate in one direction. This greatly limits the possibilities for controlling the auxiliary drive; for example, in known solutions, the auxiliary drive can only be controlled in the direction of travel (or forward direction) to assist the stroller. However, if the stroller user also needs assistance in the opposite direction of travel (or backward direction), this cannot be achieved using known solutions.

[0004] The term "baby stroller" should refer to all types of baby strollers, such as traditional baby strollers, children's sports strollers, jogging strollers, and lightweight strollers, or vehicles used for pushing and transporting infants and toddlers. Summary of the Invention

[0005] One object of the present invention is to solve the problems described above. Another object of the present invention is to provide a stroller with assisted drive and control over the assisted drive in a multifunctional, low-cost, comfortable and safe manner.

[0006] The objective is achieved by the subject matter of one claim of the respective independent claims. The objective is achieved, in particular, by a stroller having: at least three wheels, preferably four wheels; at least one drive unit, in particular a motor, preferably an electric motor; and an operating device. The at least one drive unit is configured to drive at least one wheel of the stroller. The operating device has a zero position, a first position from the zero position, in particular a first maximum position, and a second position, in particular a second maximum position, the second position preferably being opposite to the first position from the zero position. Control of the at least one drive unit is based on the position of the operating device. Here, a position of the operating device preferably corresponds to a requested forward or backward drive power and / or braking power (or, at least within a certain range of motion, the drive power or braking power depends on the position).

[0007] Braking power can be understood as the driving power applied in the opposite direction of the stroller's movement, thereby causing deceleration. Alternatively or additionally, preferably regardless of the direction of movement, braking power can also be understood as the rate at which the stroller's kinetic energy is reduced. Here, braking power can be provided by the generator-like operation of the drive unit, in which kinetic energy is converted into electrical or thermal energy.

[0008] Here, "opposite" means that when the operating device is moved from the zero position to the first position by the movement of at least a part of the operating device, in order to move it from the zero position to the second position, for example, a movement in the opposite direction is required. This applies to both linear movements (e.g., left / right, forward / backward, etc.) and rotational movements about an axis (e.g., forward and backward rotation, clockwise / counterclockwise, etc.). Thus, according to one embodiment of the invention, the movement of the stroller can be controlled simply and precisely. Here, an important aspect of the invention is that by operating the same element (i.e., the operating element), both driving power (i.e., power for accelerating the stroller) and braking power (i.e., power for decelerating or slowing down the stroller) can be requested. This aspect has the advantage of improved operational convenience because it eliminates the need to operate separate devices for driving or braking. Furthermore, in this way (e.g., by driving the stroller in the opposite direction of movement), the drive device can be used for both driving and braking the stroller, which simplifies the stroller overall and thereby saves on components and costs.

[0009] In some embodiments, the operating device is capable of moving from the zero position along a first direction, preferably toward a first position, especially a first maximum position, and / or along a second direction, preferably toward a second position, especially a second maximum position. In this case, the movement of the operating device from the zero position along the first direction can correspond to driving the stroller forward via a drive mechanism, and / or the movement of the operating device from the zero position along the second direction can correspond to driving the stroller backward via a drive mechanism.

[0010] Here, zero position corresponds to the following position of the operating device, in which no signal is issued from the operating device for driving and / or braking the stroller via the drive mechanism, even during operation.

[0011] Here, the correspondence between the movement of the operating device and the driving direction allows for more intuitive control by the user. In particular, this also results in improved ergonomics, as it avoids continuous unilateral load on the user. Specifically, in this embodiment, to brake the stroller or request braking power, the user only needs to operate the operating device in the opposite direction to the stroller's current direction of movement.

[0012] The objective is alternatively or additionally achieved, particularly by a stroller having: at least three wheels, preferably four wheels; a drive unit, particularly a motor, more preferably an electric motor; and an operating device. The drive unit is configured to drive at least one wheel of the stroller. The operating device includes a zero position and at least one first position originating from the zero position, particularly the first position and / or a second position, the second position originating from the zero position preferably opposite to the first position. The drive unit is controlled according to the position of the operating device, one position of the operating device corresponding to a requested drive power and / or a requested braking power of the drive unit.

[0013] In some embodiments, the movement of the operating device from the zero position along a first direction, preferably toward a first position, especially toward a first maximum position, corresponds to a request for forward driving power and / or a request for braking power, and / or the movement of the operating device from the zero position along a second direction, preferably toward a second position, especially toward a second maximum position, corresponds to a request for backward driving power and / or a request for braking power.

[0014] This allows for more intuitive control of the stroller.

[0015] In particular, the stroller may have a (manual) selection device configured such that, whether the selection device is not operated or is operated, drive power or braking power can be requested by movement of the operating device. Preferably, drive power is requested by movement of the operating device when not operated, and braking power is requested by movement of the operating device when operated. Alternatively or additionally, the (manual) selection device may include a first position and a second position, in which drive power of the drive device can be requested by movement of the operating device, and / or in the second position, braking power of the drive device can be requested by movement of the operating device. Preferably, the (manual) selection device can be configured as part of the operating device, but optionally it can also be configured as a separate element disposed on the stroller, particularly in the handle area of ​​the push rod section.

[0016] This device reduces the risk of unintentional user misoperation. Furthermore, it prevents, for example, children from potentially moving the stroller independently and without user intervention by operating the control mechanism, whether accidentally or intentionally. By preferably dividing the device into an operating mechanism and a selection mechanism, the user can easily switch between braking and driving modes. This, in particular, prevents the user from unintentionally accelerating or decelerating the stroller.

[0017] Similarly, this objective is achieved, in particular, by a stroller having: at least three wheels, preferably four wheels; a drive unit, especially a motor, preferably an electric motor; and preferably one or more sensors; and an operating device. The drive unit is configured to drive at least one wheel of the stroller. The operating device includes a zero position and at least one first position originating from the zero position, especially the first position and / or a second position, the second position originating from the zero position preferably opposite to the first position. The drive unit is controlled in such a way that, depending on different driving parameters of the stroller and the position of the operating device, driving power or braking power is requested, and / or driving power or braking power is transmitted to at least one wheel.

[0018] The driving parameters section provides information about the current operating status or movement of the stroller. Driving parameters may include, for example, the stroller's speed, direction of movement, drive unit speed, drive unit output power, and the charging status of any accumulators (preferably batteries).

[0019] At this point, the control device can be designed to detect itself, for example, by calculating driving parameters, or by receiving driving parameters from an external source (e.g., a sensor).

[0020] By combining driving parameters with the position of the operating devices, a variety of control possibilities can be achieved in a simple manner and form. These control possibilities improve the ergonomics of the stroller, provide greater safety, or achieve more efficient operation. For example, by comparing with the current speed, the stroller can be prevented from operating in an excessively high speed range. Alternatively, for example, acceleration performance can be adapted to the state of charge of the accumulator if necessary, so as to drive as energy-efficiently as possible when the state of charge is low (e.g., half or a quarter of full charge). Alternatively or supplemented here, driving parameters can also consist of multiple individual parameters.

[0021] In some embodiments, the stroller includes a control device configured to control the drive mechanism based on the position of the operating device.

[0022] The control device may be additionally configured to detect and / or receive different driving parameters of the stroller, especially speed and / or driving direction, for example by detecting and / or receiving the rotation direction and / or rotation speed of at least one wheel, so as to control and / or adjust the drive device according to the position of the operating device and the preferred current value of the driving parameters.

[0023] Alternatively or additionally, the stroller may include at least one sensor device, preferably a Hall effect sensor unit, capable of detecting various driving parameters of the stroller, particularly speed and / or driving direction by, for example, the rotational direction and / or speed of at least one wheel, and / or capable of transmitting these driving parameters, preferably to the control device. Preferably, the at least one sensor device may be located on, / or inside, and / or near the drive unit. Here, by placing it near the drive unit, a simpler overall structure can be achieved because the distance traversed is shorter, and the risk of wiring damage is reduced.

[0024] In an embodiment, the control device is configured to and / or control the drive device such that, such that

[0025] - When the stroller is stationary and / or the stroller's current speed is 0 km / h and / or the stroller's direction of travel and / or the rotation direction of at least one wheel is not present and / or cannot be detected, the movement of the operating device from zero position, especially along the first and / or second directions, does not request and / or transmit the drive power and / or braking power of the drive unit to at least one wheel, and / or

[0026] - When the stroller is not stationary and / or when the stroller's current speed is greater than 0 km / h and / or when there is and / or the stroller's direction of travel and / or the rotation direction of at least one wheel is detected, the operating device initiates a movement request from zero position, particularly along the first and / or second directions, and / or transmits drive power and / or braking power of the drive unit to at least one wheel, and / or

[0027] - When the current direction of travel of the stroller and / or the rotation direction of the at least one wheel is the same as the direction of the requested drive power, the movement of the operating device from zero position, especially along a first direction corresponding to the requested forward drive power of the drive device, results in the transfer of (forward) drive power to the at least one wheel, and / or when the current direction of travel of the stroller and / or the rotation direction of the at least one wheel is not the same as the direction of the requested drive power, especially opposite to the direction of the requested drive power, the movement of the operating device results in the transfer of braking power to the at least one wheel, and / or

[0028] - When the current direction of travel of the stroller and / or the rotation direction of the at least one wheel is the same as the direction of the requested drive power, the movement of the operating device from the zero position, especially along the second direction corresponding to the requested rearward drive power, results in the transmission of (rearward) drive power to the at least one wheel, and / or when the current direction of travel of the stroller and / or the rotation direction of the at least one wheel is not the same as the direction of the requested drive power, especially when it is opposite to the direction of the requested drive power, the movement of the operating device results in the transmission of braking power.

[0029] In particular, this prevents the stroller from starting or braking unexpectedly. This ensures, for example, that the stroller must first be pushed in the desired direction before adding drive power via the drive unit. This, for example, prevents a child from potentially moving the stroller independently and without user intervention by operating the control mechanism.

[0030] In some embodiments, the relationship between the position of the operating device and the requested drive power is linear, where the maximum position of the operating device corresponds to the maximum requested drive power, and the zero position of the operating device corresponds to the minimum drive power, or in particular, no drive power. However, alternatively, the relationship can also be at least partially nonlinear. For example, the requested drive power can increase more rapidly than a linear relationship, for example, in a polynomial form, such as at least a quadratic or at least a cubic form. If the operating device is, for example, rotatable and can occupy positions between 0° (zero position) and 90° (maximum position), then the requested drive power can more than double when the angle is doubled. The nonlinear relationship preferably applies to at least 10% of the maximum adjustment range, especially the adjustment angle range, preferably at least 50%, and if necessary at least 95%, and / or to the adjustment range adjacent to the initial position, especially the initial angle.

[0031] In some implementations, the relationship between the position of the operating device and the requested braking power is linear, where the maximum position of the operating device corresponds to the maximum requested braking power, and the zero position of the operating device corresponds to the minimum braking power, especially no braking power. Alternatively, however, the relationship can also be non-linear. Additionally or alternatively, the actual braking force transmitted to at least one wheel of the stroller depends on the current speed of the stroller, where the braking force preferably increases non-linearly with increasing stroller speed and reaches maximum braking force from a predetermined speed.

[0032] In this case, the relationship between the (actual) braking action and the stroller speed can be expressed, in particular, by a growth function for finite growth (limited growth), where maximum braking action is preferably achieved at a maximum speed of 4 km / h, more preferably a maximum of 3 km / h, and especially a maximum of 2 km / h. Alternatively, it can also be envisioned that the braking action increases linearly with the stroller speed. In particular, the requested braking power corresponds to the maximum braking action, meaning that the user confirms the maximum braking action of the drive unit by the position of the operating device.

[0033] In some preferred embodiments, the stroller includes a lower frame and a push rod section, the push rod section being disposed in the upper section of the lower frame. The stroller also includes at least three wheels, preferably four wheels, which may be disposed in the lower section of the lower frame.

[0034] The lower frame preferably includes a front wheel frame section and a rear wheel frame section that are rotatably connected to each other, particularly by a first hinge. The pushrod section is preferably rotatably connected to the front or rear wheel frame section by a second hinge, or movably connected to the front wheel frame section. In particular, the first and second hinges can be identical, so that the front wheel frame section, the rear wheel frame section, and the pushrod section are rotatably connected to each other at a common hinge.

[0035] Preferably, at least one wheel is a rear wheel and is disposed on the lower end and / or rear end of the rear wheel frame section, and at least one wheel is a front wheel and is disposed on the front end and / or lower end of the front wheel frame section.

[0036] The front and / or rear wheel frame section may include a right-side rod and a left-side rod, which are interconnected by at least one crossbar. The push rod section may also have a right-side rod and a left-side rod, preferably with a handle area disposed between the right and left-side rods of the push rod section. The first and / or second hinge may include a right hinge section and a left hinge section, which are interconnected by a crossbar.

[0037] The stroller may have a child-accommodating device and / or be detachably connected to such a device. The child-accommodating device particularly refers to a child seat, reclining bassinet, infant carrier, or the like. The stroller may be designed such that the child-accommodating device and / or a first adapter for connecting to it is located in the upper section of the lower frame or on the push rod section. The first adapter may include right-side and left-side adapter elements, each of which preferably has a coupling section that points particularly upwards.

[0038] In some embodiments, the stroller has a second adapter for connection to (another) child-accommodating device, the second adapter preferably being located below and / or in front of the first adapter, particularly near the at least one front wheel and / or in the lower / front region of the front wheel frame section. The second adapter may include right-side and left-side adapter elements, each of which preferably has a coupling section.

[0039] In some embodiments, the first adapter is adjustable between an upper / rear position and a lower / forward position. For this purpose, the first adapter can be movably mounted on the side rod of the push rod section. Alternatively or additionally, the second adapter can be switched between a use position and a storage position, wherein the coupling section preferably points upward in the use position. The switching between the use and storage positions of the second adapter can be achieved by rotation, flipping, and / or movement, preferably such that the second adapter extends upward further in the use position than in the storage position. This switching can be performed on the second adapter as a whole, or on each of the two adapter elements individually.

[0040] In some embodiments, the stroller includes at least one drive unit, particularly at least one motor, preferably an electric motor, such as a hub motor, wherein the drive unit is configured to drive and / or brake at least one wheel of the stroller.

[0041] In some embodiments, the drive unit is disposed in or particularly near at least one wheel, and the drive unit is connected to the at least one wheel, particularly via a drive belt. Preferably, the drive unit may be disposed in the lower region of the lower frame, particularly between two wheels, for example, between the left and right rear wheels of a stroller.

[0042] Alternatively, each wheel of the stroller can be equipped with its own drive unit. The drive unit can be configured such that its axis of rotation is the same as or different from the axle of the at least one wheel. In this case, the drive unit is connected to the at least one wheel via a drive belt, preferably with a rotational frequency higher than that of the at least one wheel.

[0043] In some embodiments, the stroller includes an energy accumulator, particularly a (rechargeable) battery, which is electrically connected to the drive unit. Preferably, the energy accumulator (rechargeable battery) is removable so that it can be charged independently of other components of the stroller. The energy accumulator may be located in or on the wheel axle connecting the two rear wheels, and / or on or in the crossbar connecting the left and right side bars. Electrical and / or wireless connection between the operating device and the drive unit can be achieved through a control device, for example, the control device may be electrically or wirelessly connected to the drive unit and electrically or wirelessly connected to the operating device. Preferably, the control device is arranged (directly) adjacent to the drive unit or the operating device.

[0044] In some implementations, the stroller includes at least two (different) electronic components, such as an accumulator, an operating device, a drive device, a sensor device, and / or a control device, and at least two or all of the electronic components can be electrically and / or wirelessly connected to each other.

[0045] In particular, at least one electrical connection is preferably provided between at least two of the at least two electronic components, preferably between at least two of the energy storage device, operating device, drive device, sensor device, and control device, and the electrical connection more preferably includes at least one cable. The at least one electrical connection can be configured such that it can (reversibly) elongate when, in particular, different sections and / or one section of the stroller frame are adjusted (e.g., rotated and / or translated) to spatially distance the at least two electronic components from each other and / or when the desired length of the electrical connection between the two electronic components changes, for example, by increasing and / or decreasing. In particular, the electronic components, preferably the energy storage device, operating device, drive device, sensor device, and / or control device, can be located in or on different sections of the stroller frame configured to move relative to each other (e.g., rotate and / or translate).

[0046] In some embodiments, the electrical connection includes at least one helical winding, preferably multiple helical windings (helical cable), and / or at least one cable loop. The helical winding of the (helical) cable can reversibly elongate when the two electronic components are moved away from each other, and / or at least one loop of the cable loop can reversibly (at least partially, but especially not completely) unwind or retract as the distance between the two electronic components increases.

[0047] In some embodiments, the stroller includes an operating device for controlling the at least one drive mechanism, where such control is based on the position of the operating device. The operating device is configured to be adjustable and / or movable and / or operable, and can occupy multiple positions, particularly a zero position and at least one first position, especially first and second positions, preferably first and second maximum positions, the second position preferably originating from the zero position and opposite to the first position.

[0048] In particular, the operating device can occupy multiple intermediate positions between the zero position and the at least one first and / or second position, preferably the first and / or second maximum position. Specifically, the operating device can be discretely positioned, preferably at least three, and especially at least five. However, it is particularly preferred that the adjustment of the operating device be stepless.

[0049] This division allows for easier operation of the stroller and higher precision in control. Furthermore, it allows for the allocation of frequently used drive power to corresponding positions, thereby improving operability. Additionally, it allows for a combination of gear settings and stepless adjustability; for example, stepless adjustment can be achieved in principle, but gears are set at specific points along the adjustment path, such as through a releasable latching mechanism.

[0050] In some embodiments, the stroller and / or operating device includes at least one sensor unit, preferably a Hall sensor unit, for detecting the (current) position of the operating device.

[0051] Therefore, more precise control can be achieved compared to control achieved by directly transmitting the position of the operating device. Furthermore, this improves comfort and durability because it eliminates (or reduces) the need to overcome mechanical resistance.

[0052] In some embodiments, the operating device is configured as a manual operating device, preferably including a lever, a rotating element, and / or a push rod. Alternatively, the operating device may also be configured as a touch input device, wherein a posture of the touch input device corresponds to a position on the touch input device.

[0053] In some embodiments, the operating device has a zero position, and the operating device is preferably designed to be preloaded toward the zero position, for example by at least one spring, preferably a tension spring, compression spring and / or torsion spring, or by at least one magnet, preferably a permanent magnet.

[0054] This improves the stroller's ease of operation. Furthermore, it provides an additional safety feature, as it ensures that the stroller will not continue to move when the user releases it.

[0055] In the case of a touch input device, when there is no interaction between the touch input device and the user, for example, when the user does not touch the touch input device, the touch input device automatically enters a zero position. The operating device can move from the zero position along a first direction and a second direction. The operating device may include a first stop and a second stop, the first stop corresponding to the (first) maximum position of the operating device in the first direction, and the second stop corresponding to the (second) maximum position of the operating device in the second direction (or optionally corresponding to the zero position).

[0056] Here, touch input offers the advantage of higher reliability because it is less likely for dirt or water to enter compared to comparable mechanical structures.

[0057] If the operating device is configured as a touch input device, the operating device may have a first and (opposite) second touch area starting from the zero position, each touch area having a corresponding maximum position, particularly at one end of the touch area.

[0058] In some embodiments, the operating device is configured to be rotatable and / or translational, and may be located on and / or near the push rod section of the stroller, preferably in the handle area. The operating device may be rotatably supported about a longitudinal axis of the handle area or about an axis perpendicular to or parallel to the longitudinal extension of the handle area. Alternatively or additionally, the operating device may be configured such that it is movable along a straight line defined by the longitudinal extension of the handle area, or the operating device may be configured such that it is movable along a straight line perpendicular to or parallel to the longitudinal extension of the handle area.

[0059] In some embodiments, the operating device may be configured to be rotatable, and in particular, it may occupy a position between 0° (zero position) and a maximum of 90° (maximum position), preferably a maximum of 60°, more preferably a maximum of 45°, and / or at least 20°, preferably at least 30°, starting from 0° or zero position and moving in two opposite directions.

[0060] In some embodiments, the operating device is configured to be translationally movable and can occupy a position on a (straight) line segment having a first end and a second end, particularly a first stop and a second stop, which correspond in particular to the first and second maximum positions. Preferably, the zero position is located in the middle section of the line segment, particularly directly at the midpoint of the line segment. In particular, the line segment can have a maximum length of 15 cm, preferably 10 cm, more preferably 5 cm, and / or a minimum length of at least 1 cm, preferably at least 2 cm, more preferably at least 3 cm.

[0061] In some embodiments, the operating device is disposed on the front, rear, upper and / or lower side and / or in the middle of the handle area, or near the handle area, particularly in a rotatable and / or translatable manner. The operating device may protrude from the handle area and / or be disposed on the handle area such that the operating device terminates flush with the surface of the handle area and / or at least partially abuts against the handle area.

[0062] In some embodiments, the operating device includes a fixed section and at least one (first) operating section, particularly a first operating section and a second operating section. The operating device is rotatably and / or movably connected to the handle area via the fixed section. Preferably, the operating device is configured as a lever, particularly a substantially V-shaped or L-shaped lever, in which case the operating device has a first operating section and a second operating section, and is rotatably connected to the handle area about a rotation axis via the fixed section, preferably connected to the underside of the handle area.

[0063] At this point, the V-shaped or L-shaped design of the operating device allows for ergonomic movement using the user's fingers, preferably the thumb. An L-shape here refers to an operating device having at least two substantially straight sections, said sections having approximately right angles (i.e., between 110 and 70 degrees, preferably between 100 and 80 degrees) with respect to each other. A V-shape here refers to an operating device having at least two substantially straight sections, said sections having acute angles (i.e., less than 45 degrees, preferably less than 30 degrees) with respect to each other.

[0064] In some embodiments, the fixed section includes a fixed segment and a movable segment, the fixed segment being connected to and / or formed, in particular, by the push rod segment, especially its handle area. Specifically, the movable segment is capable of rotational and / or translational movement relative to the fixed segment.

[0065] The movable segment preferably includes at least one (first) operating segment, particularly a first operating segment and a second operating segment. The fixed segment, preferably its fixed segment and / or movable segment, and / or handle area may include first and / or second stops corresponding to the first and / or second maximum positions of the operating device. The first and / or second stops may be formed, in particular, by at least one protrusion and / or at least one recess.

[0066] The stop allows the operating device to reach its maximum or minimum position in a simple and stable manner. This prevents malfunctions caused by excessive movement of the operating device.

[0067] In some embodiments, the fixed section, particularly its fixed or movable segment, and / or handle area includes (guide) grooves and / or recesses and / or guide rails to guide the movement of the operating device. In particular, the first and second ends of the (guide) grooves and / or recesses and / or guide rails may form the first and second stops. Preferably, the stop element cooperating with the first and second stops extends at least partially into the (guide) grooves and / or recesses and / or guide rails. The stop element, preferably a protrusion, may be provided on the fixed section, particularly its fixed or movable segment, and / or on the handle area, and the stop element is particularly not provided on the same element including the (guide) groove and / or recess and / or guide rail.

[0068] In some embodiments, at least one spring, preferably a tension spring, compression spring, and / or torsion spring, is provided between the fixed segment and the movable segment, and / or at least one magnet, preferably a permanent magnet, is provided, which preloads the movable segment toward the zero position of the operating device.

[0069] In some embodiments, the operating device, preferably the fixed section, especially its fixed or movable section and / or handle area, includes at least one sensor unit, preferably a Hall sensor unit, to detect the current position of the operating device. Similarly, the operating device, preferably the fixed section, especially its fixed or movable section and / or handle area, may have at least one magnet, especially a permanent magnet, which cooperates with the sensor unit. In this case, the at least one magnet is not located on the same element as the at least one sensor unit. Specifically, the sensor unit, preferably a Hall sensor unit, may be located within the fixed section, and the at least one magnet, preferably a permanent magnet, may be located within the movable section, or vice versa.

[0070] In some embodiments, the first operating section extends rearward from the fixed section and / or the second operating section extends forward from the fixed section. In particular, it is preferable that, in the zero position of the operating device, one end of the first operating section faces toward and / or is located near the rear end of the handle area, and / or one end of the second operating section faces toward and / or is located near the front end of the handle area.

[0071] Furthermore, preferably in the zero position of the operating device, the first operating section may be positioned at a first height level (from the substantially horizontal ground where the stroller is located) and / or the second operating section may be positioned at a second height level (from the substantially horizontal ground where the stroller is located), the first height level preferably being below the second height level, optionally above the second height level, or at the same height. Specifically, this may mean that the lower edge of the second operating section is above the lower edge of the first operating section (when the stroller is on the substantially horizontal ground and the operating device is in the zero position).

[0072] In some embodiments, the fixed section, especially its movable section, is substantially located on a first (horizontal) plane with the first and / or second operating section, preferably with the second operating section, and the corresponding other (first or second) operating section, preferably the first operating section, points downward (optionally upward) from the (horizontal) plane, and its longitudinal direction defines a second plane, the first plane forming an angle of at least 10°, preferably at least 30°, more preferably at least 45° and / or a maximum of 90°, preferably, a maximum of 75°, more preferably a maximum of 60° with the second plane.

[0073] The operating device is specifically configured such that while the user's hand is holding the handle area of ​​the push rod section, the user can operate the first operating section with the thumb and the second operating section with the index finger.

[0074] This makes it safer and easier to operate the stroller, especially with just one hand.

The push rod section 120 includes a left rod and a right rod 121, and a handle area 122 disposed between the left rod and the right rod 121. The handle area 122 includes an operating device 230. The left rod and the right rod 121 each have a guide rail 102 on their inner sides, on which a first adapter 170 is movably disposed, shown in the lower position in this figure.

[0083] The front wheel frame section 130 also has a left side bar and a right side bar 131, which are connected to each other by a crossbar 132. A second adapter 180 is provided on the inner side of the side bar 131 of the front wheel frame section 130. Two front wheels 191 are provided on the lower front end of the front wheel frame section 130, and the upper rear end of the front wheel frame section 130 is rotatably connected to the lower front end of the push rod section by a first hinge 150. The rear wheel frame section 140 also includes a right side bar and a left side bar 141, which are connected to each other by a crossbar 142, and an energy accumulator 220 is provided on the crossbar 142. The upper front end of the rear wheel frame section 140 is connected to the front wheel frame section 130 by a second hinge 160. Rear wheels 192 are provided on the lower rear end of the rear wheel frame section 140, and each rear wheel 192 is driven by a motor (drive device) 210.

[0084] Figure 2 Show Figure 1 The rear wheel frame section 140 of the stroller 100 is located at its lower rear end. An accumulator 220 is mounted on a crossbar 142 between the left and right side bars 141 at the lower rear end of the rear wheel frame section 140. A motor (drive unit) 210 is mounted on each of the two rear wheels 192 (only one motor or drive unit 210 is visible in this view). Furthermore, a parking brake 101 is mounted on the rear wheels 192 to prevent the stroller 100 from accidentally rolling away when not in use.

[0085] Figure 3 An exemplary configuration of a stroller 100 according to the present invention is illustrated schematically. The control device 240 may be electrically or wirelessly connected to the operating device 230, the motor (drive unit) 210, and the sensor device 250. The motor (drive unit) 210 may be electrically connected to the energy storage device 220. The control device 240 may be configured to receive data from the sensor device 250, such as the speed and / or direction of travel of the stroller 100 and / or the rotation direction of at least one wheel 190, and / or from the operating device 230, such as the position of the operating device, and / or from the motor (drive unit) 210.

[0086] Figure 4a and 4bAn exemplary electrical connection 270 of a stroller 100 according to the invention is shown schematically. The electrical connection 270 is formed between two electronic components, here for example, between an operating device 230 and a control device 240. The electronic components are located on two different sections of the stroller 100, such as a push rod section 120 and a rear wheel frame section 140. The push rod section 120 can be adjusted, in particular, by translation (or its length can be increased and / or decreased), thereby changing the necessary length of the electrical connection between the two electronic components, for example, depending on the increase and / or decrease in the length of the push rod section 120. The electrical connection 270 is exemplary configured as a spiral cable 271, which is configured such that the spiral cable can be (reversibly) extended to adaptively adjust to the current length of the push rod section 120. Thus, Figure 4a The electrical connection 270 or the spiral cable 271 is shown in its normal (unstretched) state. Figure 4b The electrical connection 270 or the spiral cable 271 is shown in a (reversibly) elongated state.

[0087] Figure 5 An embodiment of a stroller 100 with an electrical connection 270 according to the invention is shown. The electrical connection 270 is disposed inside a push rod section 120 and extends from the handle area 122 of the push rod section (particularly from the operating device 230) to a control device 240 disposed on a rear wheel frame section 140. The electrical connection 270 includes a spiral cable 271 disposed in the push rod section 120, the push rod section being adjustable in length. When the length of the push rod section 120 increases (or decreases again), the spiral cable 271 can (reversibly) lengthen, thereby similarly increasing (or decreasing) the length required for the electrical connection 270 between the operating device 230 and the control device 240.

[0088] Figure 6 The push rod section 120 of the stroller 100 according to the present invention is shown, especially its handle area 122. An operating device 230 is disposed on the underside of the handle area 122. Here, the L-shaped or V-shaped configuration of the operating device 230 can be particularly seen, a configuration that facilitates operation by the user's thumb.

[0089] Figure 7 The operating device 230 and handle area 122 are shown below. The operating device 230 includes a fixing section 234 through which it is pivotally (or rotatably) connected to the underside of the handle area 122 about a rotation axis 233. From the fixing section 234, a first operating section 231 extends rearward (upward in the figure), while a second operating section 232 extends forward (downward in the figure).

[0090] Figure 8 The operating device 230 and handle area 122 are shown from the front. The fixed section 234 of the operating device 230 includes a fixed segment 238 and a movable segment 239, the fixed segment 238 being connected to the handle area 122 of the push rod section 120. The movable segment 239 is rotatably connected to the fixed segment 238 about a rotation axis 233 and includes a first operating segment 231 and a second operating segment 232. A sensor unit, particularly a Hall sensor, is disposed inside the fixed segment 238, and a magnet, particularly a permanent magnet (not shown), is disposed inside the movable segment 239 to detect the position of the movable segment 239 relative to the fixed segment 238.

[0091] Figure 9 The fixed segment 238 of the fixed section 234 of the operating device 230 is shown below. The fixed segment 238 includes a (guide) groove 237, into which a stop element, particularly a protrusion, of the movable segment 239 extends at least partially (not shown). Corresponding first and second ends of the (guide) groove 237 form a first stop 235 and a second stop 236, which correspond to a first maximum position and a second maximum position of the operating device 230. A (torsion) spring 260 is disposed inside the fixed segment 238, which preloads the movable segment 239 toward the zero position of the operating device 230.

[0092] Figure 10 An embodiment of the stroller 100 is shown from the front. An operating device 230 is located below the handle area 122 of the push rod section 120 and is in the zero position. The operating device 230 includes a first operating section 231 and a second operating section 232. The first operating section is located at a first height level H1 (from the substantially horizontal ground where the stroller 100 is located), and the second operating section is located at a second height level H2, with the first height level H1 located below the second height level H2. That is, the lower edge of the second operating section 232 is located above the lower edge of the first operating section 231 (when the stroller is placed on the substantially horizontal ground and the operating device is in the zero position).

[0093] Figure 11 A cross-section of the handle region 122 is shown, with the operating device 230 positioned below it. It can be seen that the movable segment 239 of the fixed segment 234 is substantially on a (horizontal) plane E1, which is substantially aligned with the second operating segment 232. The first operating segment 231 extends downwards from plane E1, and its longitudinal direction defines plane E2. These two planes, E1 and E2, form an angle W1. The angle W1 is at least 10°, preferably at least 30°, more preferably at least 45°, especially a maximum of 90°, preferably a maximum of 75°, and more preferably a maximum of 60°.

[0094] Figures 12a to 12c The diagram schematically shows a cross-section of the handle region 122 of the push rod. The operating device 230 is configured as a (rotatable) segment of the handle region 122, and surrounds the handle region in the shown segment, and is rotatably supported about the handle region 122 (about an axis perpendicular to the plane of the figure). The handle region 122 has a first stop 235 and a second stop 236, particularly first and second protrusions. The operating device 230 includes corresponding stop elements that cooperate with the first stop 235 and the second stop 236 to limit the rotation of the operating device 230 about the handle region 122. In the figure, the rotation is limited to within 90°. Figure 12a The zero position of the operating device is shown. Figure 12b and 12c The operating device 230 is shown in its respective (first and second) maximum positions, such that the position of the operating device 230 is at an angle of 45° from the zero position or from the zero position.
