ELECTRIC CARGO SCOOTER

Description

[0001] The present invention relates to an electrically driven cargo scooter, and further discloses a cargo scooter control and / or regulation system, a method for controlling and / or regulating an electrically driven cargo scooter and a computer program product for executing the aforementioned method by means of a computer.

[0002] Various cargo scooter variants are known from the prior art. These include a footboard and wheels, as well as a mounting device for loads, such as a suitcase or a suitcase holder. Such conventional scooter variants aim to promote people's mobility in a practical way. An example of this type of cargo scooter is known from PCT / EP2019 / 086679.

[0003] PCT / EP2019 / 086679 describes a variable small vehicle with an electric drive that can be varied between two states: a basic state in which a load area and a standing area behind it are provided, and a shortened state compared to the basic state in which either the load area or the standing area is deactivated. In both states, only exactly two axles, namely a front axle and a rear axle, are actively on the ground. A method for conveniently changing the state of the small vehicle is also disclosed.

[0004] ES 1 262 134 U describes an electric scooter for load transport, comprising: a tubular chassis with a rear platform configured to carry a user and a front platform configured to carry a load; a pair of driving front wheels attached to the front platform, the front wheels being fixedly aligned in the direction of travel; at least one rear steering wheel attached to the rear platform and coupled to a shaft rotating relative to the vertical; a vertical steering frame arranged between the rear platform and the front platform, the vertical steering frame comprising a handlebar connected to a vertical steering axis, which in turn is connected to the axis of the rear wheel, such that when the user turns the handlebar, a change in the orientation of the rear wheel occurs, causing the scooter to rotate.

[0005] US 6,273,206 B1 describes a motor-driven collapsible chair vehicle having a frame supported on front and rear wheels. A steering column is mounted at the front end of the frame, and a seat is supported at the rear thereof. The frame has separate front and rear segments containing a longitudinally telescopic coupling arrangement consisting of a longitudinally telescoping part on one of the segments, which is received by a receiving part on the other segment, and a locking arrangement connected to one of the parts and, upon relative telescopic movement of the parts, automatically interacts with the other and locks them in the locked position.

[0006] EP 3 650 325 A1 describes a single-seat electric vehicle comprising a chassis carrying at least three wheels distributed over two rolling assemblies, including a pivotable rolling assembly, at least one of the rolling assemblies being electrically driven, a platform for supporting a driver; a platform for supporting a load; and an orientation actuator having a drive shaft rotatably connected to the pivotable rolling assembly by a rotatable connecting element and controlled by means of a directional control element.

[0007] Cargo scooters designed to promote mobility in the future are subject to a variety of requirements defined by their specific field of application, for example, by who or what is to be transported and by the routes to be used for transport.

[0008] It is therefore an object of the present invention to provide a cargo scooter which is accessible to a multitude of application fields and enables a particularly simple and reliable transition between different transport routes or situations.

[0009] The above-described object is achieved by the subject matter of the independent claims, preferred embodiments are the subject matter of the dependent claims.

[0010] The claimed invention is defined by an electrically driven cargo scooter according to the appended claims 1 to 15.

[0011] The claimed invention relates to an electrically driven cargo scooter, comprising: a front axle with at least one front wheel, wherein the front axle is arranged on a front frame part; a rear axle with at least one rear wheel, wherein the rear axle is arranged on a rear frame part; -- wherein the cargo scooter has a short state in which one of the rear frame part and the front frame part is at least partially arranged in the other of the rear frame part and the front frame part; and a footboard; characterized in that -- the footboard has a rear wheel release device which is configured to release pivotability of at least one rear wheel in the short state of the cargo scooter.

[0012] Advantageously, the present electrically driven cargo scooter enables the electrically driven cargo scooter to be particularly maneuverable and to have a particularly small turning circle in a short state, i.e. in particular after a transition from a long state to the short state by releasing the pivotability of at least one rear wheel.

[0013] Due to the increased maneuverability in the short position of the cargo scooter, the cargo scooter is particularly suitable not only for transporting a load up to a building, but also for transporting it into the building, which also makes transport routes into offices or living spaces accessible for the cargo scooter, which can lead, for example, via elevators or similar.

[0014] The pivotability of a rear wheel means in particular the rotation of the rear wheel about its vertical axis or about an axis about which the rear wheel is rotatably mounted for a steering movement of the cargo scooter.

[0015] In exemplary embodiments, the pivotability of the at least one rear wheel can be released by means of the rear wheel release device of the footboard such that the at least one rear wheel can be pivoted by at least approximately 90°, preferably up to approximately 180°, and particularly preferably by 360°. In the latter case, the at least one rear wheel can be pivoted or rotated completely around its vertical axis.

[0016] The short state of the cargo scooter can in particular be a state in which the cargo scooter is shortened compared to another state of the cargo scooter, which can be referred to as the long state, in particular is shortened in its longitudinal direction. The short state of the cargo scooter can, for example, describe a state of the cargo scooter in which one of the rear frame part and the front frame part is at least partially arranged in the other of the rear frame part and the front frame part or is received in the other of the rear frame part and the front frame part. For example, the short state of the cargo scooter can correspond to a state in which the rear frame part is almost completely received in the front frame part or vice versa. Furthermore, the long state of the cargo scooter can correspond to a state in which the front frame part is almost completely received in the rear frame part or vice versa.

[0017] In other words, the cargo scooter can have a frame comprising a front frame part and a rear frame part. The front frame part and the rear frame part can be arranged so as to be displaceable relative to one another, in particular in the longitudinal direction of the cargo scooter. For example, the front frame part and the rear frame part can be designed to be telescopic relative to one another, but are not limited to this. In particular, the front frame part and / or the rear frame part can be configured to each accommodate or accommodate only a section of the other, at least in sections, in the short state and in the long state.

[0018] By arranging the rear axle on the rear frame part and the front axle on the front frame part, the short state can be configured in particular in that the rear axle and the front axle have a shortened distance from each other, compared to a long distance in a long state of the cargo scooter.

[0019] In preferred embodiments, the short state can be defined by the distance between the rear axle and the front axle being shorter than the distance between two wheels arranged on the front axle or the rear axle. This makes it possible to provide a cargo scooter whose turning circle in the short state is advantageously small, in particular so small that a turning circle radius is defined only or exclusively by the distance between two wheels arranged on the front axle or the rear axle. In exemplary embodiments, the cargo scooter in the short state can have a turning circle radius of less than approximately 1.5 m, preferably less than approximately 1.3 m, more preferably of approximately 1.1 m, and particularly preferably of approximately 1.0 m.The aforementioned realizable turning circle radii represent exemplary turning circle radii of the present cargo scooter according to the invention, whereby, depending on the desired dimensions of the cargo scooter, turning circles above or below these can also be realized.

[0020] In further preferred embodiments, two wheels on one axle can be driven in opposite directions. For example, two wheels can be arranged on the front axle of the cargo scooter, whereby alternatively or additionally, two wheels can also be arranged on a rear axle. In the short state, the two wheels can be configured such that one of the two wheels can be driven forward and the other of the two wheels can be driven rearward. By means of the present preferred embodiment, the turning circle of the cargo scooter can advantageously be reduced even further.Thus, in the exemplary case of a cargo scooter according to the invention with two front wheels on a front axle and a rear wheel with released pivoting, the turning circle radius can be defined by a distance between the axle center of the front axle and a front wheel which is arranged on the front axle, for the case when the cargo scooter is shortened in such a way that the distance between the front axle and rear axle is smaller than the distance between the front axle center and a front wheel. Alternatively, the turning circle radius can be defined by a distance between the front axle and rear axle, for the case when the cargo scooter is shortened in such a way that the distance between the front axle and rear axle is greater than the distance between the front axle center and a front wheel. The drivability of two wheels on one axle in opposite directions can require an additional drive method orrepresent an additional drive method, which in particular supports or enables turning the cargo scooter with advantageously minimal space requirements. In addition, the cargo scooter has a normal drive method, whereby the wheels arranged on an axle can be driven in the same direction. The opposite drivability of two wheels on an axle can be advantageously enabled, for example, by means of local motors, whereby, for example, each wheel is connected to a local motor that drives only the individual wheel connected to it. Alternatively or additionally, a local motor can also be configured to drive a plurality of individual wheels.

[0021] Compared to the statements regarding the turning circle of the cargo scooter in the short position, the cargo scooter according to the invention can have a turning circle radius in the range of approximately 1.8 m to approximately 2.5 m, preferably approximately 2.2 m, in the long position. As a result, the cargo scooter in the long position preferably has a high cornering stability, which makes it easier for the user to ride at higher speeds, such as in road traffic.

[0022] In exemplary embodiments, the front frame part and the rear frame part can be arranged to be displaceable relative to one another by means of a rail system.

[0023] In alternative embodiments of the cargo scooter, the front frame part and the rear frame part can also be pushed past each other in order to convert the cargo scooter from a long state to a short state, and vice versa.

[0024] In preferred embodiments of the cargo scooter, the at least one rear wheel of the cargo scooter can have limited pivotability when the cargo scooter is in the extended state, in particular can be completely blocked with regard to pivotability. In exemplary embodiments, the pivotability of the at least one rear wheel when the cargo scooter is in the extended state can be limited in particular to a range of up to approximately 15°, preferably up to approximately 8°, more preferably up to approximately 3°, even more preferably up to approximately 1°, and particularly preferably around approximately 0°, wherein the specified angular range refers in each case to the pivotability or rotation about the vertical axis of the rear wheel or about the axis about which the rear wheel is rotatably mounted.

[0025] The limited pivoting ability of at least one rear wheel of the cargo scooter advantageously increases driving stability at comparatively high speeds of the cargo scooter, such as when driving on roads normally used by motor vehicles.

[0026] The combination of the free pivoting of at least one rear wheel in the short position of the cargo scooter and the restricted pivoting of at least one rear wheel in the long position of the cargo scooter enables this cargo scooter to be a beneficial system for both fast transport on roads and maneuverable transport within buildings. This allows goods or people, for example, to be transported with high time efficiency and ergonomics that are beneficial for the user.

[0027] In exemplary embodiments of the cargo scooter, the rear wheel release device can form a projection that is preferably configured to extend through an opening or flap toward the at least one rear wheel when the cargo scooter is in a short position and to cooperate with a rear wheel securing device such that the pivotability of the at least one rear wheel is released. The pivotability of the rear wheel can be released, in particular, by folding away a locking mechanism of the rear wheel. The rear wheel release device can, for example, be a projection extending from an underside of the footboard, which preferably has a roller, a wheel, a ball, or other element suitable for sliding or rolling. The element suitable for sliding or rolling can preferably be arranged at an end of the projection that is distal from the footboard.

[0028] By providing the rear wheel release device as a projection, the rear wheel release device is advantageously designed as a passively acting element which releases the pivotability of the at least one rear wheel in a passive manner, in particular by positioning the footboard in an upwardly pivoted state and by pushing the front frame part together with the rear frame part.

[0029] In further exemplary embodiments of the cargo scooter, the footboard can, in particular, be in a position suitable for riding when the cargo scooter is in its extended state, or can be arranged on the frame parts in a position suitable for riding. In other words, the footboard can be positioned approximately horizontally when the cargo scooter is in its extended state, or can be in a position that allows a user of the cargo scooter to stand on it while using the scooter.

[0030] In contrast, in the short position of the cargo scooter, the footboard can be positioned in a folded-up or pivoted position, or in a position that prevents a user of the cargo scooter from standing on it while using the scooter. The folded-up position can be a position in which the footboard is folded upwards at an angle of approximately 60° to approximately 100° relative to the longitudinal direction of the cargo scooter, for example, an approximately vertical position, and can also correspond to a position in which the footboard is approximately parallel to a steering device of the cargo scooter.

[0031] The rear wheel release device can be arranged, in particular, on the underside of the footboard. When the cargo scooter is in its extended state, i.e., particularly when the footboard is in a position suitable for riding, the rear wheel release device can be arranged in a recess in the rear frame part of the cargo scooter, wherein the recess can preferably have a ramp section. The recess in the rear frame part of the cargo scooter can advantageously enclose the rear wheel release device in its extended state and separate it from the roadway, thus protecting the rear wheel release device while riding the cargo scooter.

[0032] The transition of the footboard between the driving position and the folded-up position can be achieved in particular by means of a mechanical and / or hydraulic folding device.

[0033] Additionally or alternatively, the transition of the footboard between the driving position and the folded-up position can be effected in particular by manual folding or pivoting, in particular about a transverse axis.

[0034] When folding, the ramp section of the rear frame part and the rear wheel release device can cooperate in a supporting manner such that only a reduced force has to be applied, in particular for folding up the footboard.

[0035] Both the mechanical and / or hydraulic folding device and the interaction of the ramp section with the rear wheel release device ensure a simple and ergonomic transition between the driving position and the folded-up position of the footboard.

[0036] In exemplary embodiments of the cargo scooter, a transition between the long state and the short state of the cargo scooter can be effected by locking the at least one front wheel of the front axle and simultaneously driving the at least one rear wheel of the rear axle, or by locking the at least one rear wheel of the rear axle and simultaneously driving the at least one front wheel of the front axle, thereby providing the user with a particularly simple and ergonomic transition between the long state and the short state of the cargo scooter.

[0037] In particularly preferred embodiments of the cargo scooter, the transition from the long state to the short state can occur, at least in sections, in parallel with the transition of the footboard from the riding position to the folded-up position. This enables a particularly time-saving change of state of the cargo scooter when transitioning from one transport route to another, such as from approaching a building in the long state to entering a building in the short state, or vice versa.

[0038] In exemplary embodiments, the aforementioned transition between the long and short states, which occurs at least partially in parallel with the transition of the footboard, can be achieved by locking the at least one front wheel and driving the at least one rear wheel, or vice versa, whereby the displacement of the rear frame part and the front frame part relative to each other presses the ramp section against the rear wheel release device in such a way that the footboard is folded up in a guided manner. This advantageously allows for a time-saving and ergonomic transition between the long and short states of the cargo scooter.

[0039] Furthermore, the transition from a long position to a short position may be prevented or blocked, in particular, as long as the footboard is fixed in a position suitable for riding by the user. The transition from a long position of the cargo scooter to a short position may, for example, require a prior step of releasing the footboard's fastening, for example, from the rear frame part.

[0040] In the following, various terms are used repeatedly, the understanding of which is intended to be facilitated by the following definitions.

[0041] Electric-powered cargo scooter: In this context, an electric-powered cargo scooter is understood to mean, in particular, a scooter-like vehicle or vehicle that has at least one front wheel, preferably two front wheels, and one rear wheel, which is suitable for transporting loads, for example, in the form of other people or passengers, packages, groceries, or other goods, and which in particular has at least one electric motor as its drive. Nevertheless, the present aspects and embodiments are not limited to a cargo scooter, which explicitly requires at least one electric motor as its drive. Rather, the cargo scooter can in principle also be driven, for example, by an internal combustion engine or a fuel cell.However, a cargo scooter with at least one electric motor is advantageous in that it can be easily charged, for example, from a power outlet, or made ready for use by quickly changing the battery. Furthermore, a cargo scooter with an electric motor as its drive system avoids emissions during travel, making it particularly suitable for operation or for transporting goods in enclosed buildings, such as office spaces or residential areas. If reference is made above and below to a "cargo scooter" without further reference to the drive system, the term "electrically powered cargo scooter" should be used.

[0042] Longitudinal direction: The longitudinal direction describes a direction that essentially corresponds to the direction of movement of the cargo scooter when traveling approximately in a straight line forward. The longitudinal direction can therefore essentially correspond to a direction of the cargo scooter from back to front, along a distance between the rear axle and the front axle of the cargo scooter. The forward and backward directions of travel are in particular approximately parallel to the longitudinal direction of the cargo scooter, whereby the forward direction of travel can correspond to the longitudinal direction, and the backward direction of travel can be parallel and opposite to the longitudinal direction. The longitudinal direction can, for example, also indicate a direction in which a front frame part and a rear frame part of the cargo scooter can be moved relative to one another.

[0043] Height direction: The height direction is generally perpendicular to the longitudinal direction and essentially corresponds to a normal on an imaginary surface on which the cargo scooter is movable.

[0044] Width direction: The width direction is generally essentially perpendicular to the longitudinal direction and the height direction. The width direction can, in particular, approximately correspond to a direction in which a front axle and / or a rear axle of the cargo scooter extends. The width direction can also be referred to as the transverse direction or the transverse direction. Furthermore, various transverse axes can, in particular, extend essentially in the width direction.

[0045] The vertical, horizontal, and longitudinal directions can form a coordinate system, particularly a right-hand coordinate system. These directions have no specific origin on the cargo scooter and rather relate the elements or parts designated by them to one another.

[0046] Turning circle: The turning circle represents the smallest circle, relative to the outermost element of the cargo scooter, in which the cargo scooter can perform a circular turn. In other words, the turning circle represents a circle beyond which no element of the cargo scooter extends when the cargo scooter, by traveling in the tightest possible circle, assumes a direction of travel that is rotated by 180° from the previous direction of travel before turning or entering the tightest possible circle. The turning circle also refers, in particular, to the diameter of a turning circle. The turning circle radius is half the turning circle or the turning circle diameter.

[0047] If a direction or an angle is described with the addition "essentially" or "approximately", this addition is intended to mean or be understood to mean a deviation from the direction or angle in question in the range from 0° to 5°.

[0048] If a spatial measure, a spatial ratio or any other ratio is described with the addition "essentially" or "approximately", this addition is intended to mean or be understood to mean, in particular, a deviation from the relevant measure or ratio in the range of 0% to 10%.

[0049] In preferred embodiments of the electrically driven cargo scooter, the rear frame part can have a resiliently deflectable rear wheel securing device which secures the at least one rear wheel against pivoting in a long state of the cargo scooter.

[0050] The resiliently deflectable rear wheel locking device advantageously provides passive protection for the rear wheel against pivoting or twisting about its vertical axis. Securing the rear wheel against pivoting further increases the driving stability and safety of the cargo scooter, particularly at higher speeds, such as on roads normally used by motor vehicles.

[0051] In preferred embodiments of the electrically driven cargo scooter, the footboard can be pivoted in the short state of the cargo scooter compared to the long state of the cargo scooter, and the rear wheel release device of the footboard can be configured in the short state of the cargo scooter to deflect the resiliently deflectable rear wheel securing device in order to release the pivotability of the rear wheel.

[0052] In other words, the footboard can be folded, in particular folded up or pivoted upwards, in the short state of the cargo scooter compared to the long state of the cargo scooter, so that the rear wheel release device deflects the resiliently deflectable rear wheel securing device in such a way that the pivotability or rotation of the rear wheel about its vertical axis is released.

[0053] The linking of the pivoted or folded-up state of the footboard with the short state of the cargo scooter, so that the pivotability of at least one rear wheel is released, advantageously enables the cargo scooter to be steered in a particularly maneuverable and space-saving manner in its short state, and advantageously enables the cargo scooter to have a particularly high level of driving stability and driving safety for the user in its long state, in which the resiliently deflectable rear wheel securing device restricts the pivotability of at least one rear wheel.

[0054] In other words, the present cargo scooter advantageously enables two mutually contradictory transport situations, such as road travel on the one hand and transport within buildings on the other, to be linked or combined in an advantageously safe and ergonomic manner.

[0055] In preferred embodiments of the electrically driven cargo scooter, the resilient rear wheel securing device can have a resiliently foldable groove element, wherein a securing projection is arranged on the at least one rear wheel, and wherein in the long state of the cargo scooter the securing projection engages at least in sections in the resiliently foldable groove element.

[0056] In alternative embodiments of the cargo scooter, the resilient rear wheel securing device can have a resiliently foldable securing projection, wherein a groove element is arranged on the at least one rear wheel, and wherein in the long state of the cargo scooter the resiliently foldable securing projection engages in the groove element.

[0057] The arrangement of a resiliently foldable element and an element coupled to the rear wheel consisting of a groove and a projection engaging therein at least in sections advantageously enables a simple, passive, mechanically secure fixing of the rear wheel when the cargo scooter is in the long position.

[0058] The resiliently foldable groove element or the resiliently foldable securing projection can, for example, have a spring arrangement, preferably a torsion spring arrangement, which allows a resilient or elastic rotation of the respective element about a transverse or width direction of the cargo scooter. However, the resilient rear wheel securing device is not limited to this.

[0059] Thus, in the short state of the cargo scooter, the rear wheel release device can be configured in particular to extend through a folding opening or rear wheel opening, for example, to resiliently deflect the resiliently foldable groove element to release an engagement between the groove element and the securing projection, and to release the pivotability of the at least one rear wheel. Furthermore, in the long state of the cargo scooter, the rear wheel release device can be configured in particular not to extend through the folding opening or rear wheel opening, so that the groove element and the securing projection remain engaged due to the resilient design and block or restrict the pivotability of the at least one rear wheel.

[0060] In exemplary embodiments, the groove can be designed in particular as a conical or triangular opening groove in order to advantageously facilitate or ensure engagement with one another during a transition from the short state to the long state of the cargo scooter.

[0061] Additionally or alternatively, the securing projection or groove element can be arranged on the at least one rear wheel by means of a rotatable rear wheel suspension. Preferably, the securing projection or groove element can be arranged on the same side as the center of the rear wheel with respect to a rotational axis or vertical axis of the rotatable rear wheel suspension.

[0062] The following briefly describes the exemplary embodiment, wherein the resilient rear wheel securing device has a groove element, and wherein a securing projection is arranged on the rear wheel or on the rotatable rear wheel suspension. In alternative embodiments, the resilient rear wheel securing device can have a securing projection, and a groove element can be arranged on the rear wheel or on the rotatable rear wheel suspension. The aforementioned alignment with respect to the axis of rotation of the rear wheel suspension advantageously makes it possible for the rear wheel to automatically align itself when the rear wheel moves backward in the direction of travel in such a way that the center of the rear wheel is in front of the axis of rotation of the rear wheel suspension in the forward direction of travel, i.e. the center of the rear wheel with respect tothe axis of rotation of the rear wheel suspension is aligned further forward in the direction of travel, and in particular is automatically aligned approximately along the longitudinal direction of the cargo scooter, since this is the stable position of at least one rear wheel when the rear wheel moves rearward in the direction of travel. This further enables the safety projection, which is arranged on the rotatable rear wheel suspension, to be positioned or aligned facing the front area of ​​the cargo scooter when the rear wheel moves backward in the direction of travel. Thus, when the rear wheel moves backward in the direction of travel, it is advantageously made possible for the engaging elements to be safely and reliably aligned with one another when the resiliently foldable groove element is folded back, and to engage when the cargo scooter reaches the long state.

[0063] In preferred embodiments of the electrically driven cargo scooter, a rear wheel pivot sensor can be arranged in the region of the resiliently foldable groove element and can be configured to detect at least partial engagement of the securing projection and / or to detect non-engagement of the securing projection.

[0064] By detecting the at least partial engagement or non-engagement between the resilient rear wheel securing device and the complementary element arranged on the rear wheel, a rear wheel status signal can advantageously be generated. After evaluation of the rear wheel status signal by a cargo scooter control and / or regulation system, a drive control or regulation command can be issued that enables or sets a predetermined acceleration and / or speed of the front axle and / or the rear axle. In the event of engagement, in particular, a predetermined acceleration and / or speed can be enabled. Instead, in the event of non-intervention, a predetermined acceleration and / or speed can be prevented, in particular blocked or limited.This can advantageously prevent the cargo scooter from accelerating beyond a certain level, or even prevent the cargo scooter from accelerating at all if the resettable rear wheel locking device and the element complementary to it are not engaged, which in turn increases user safety, especially during a transition between the long and short states.

[0065] In exemplary embodiments of the cargo scooter, the rear wheel pivot sensor may in particular comprise or be a proximity sensor which is configured to detect the approach of the securing projection.

[0066] For this purpose, the rear wheel pivot sensor can preferably be arranged fixed relative to a predetermined engagement position in the groove element.

[0067] Alternatively or additionally, the rear wheel pivot sensor may comprise or be a contact sensor, an optical sensor, a spring sensor, a magnetic sensor, an ultrasonic sensor and / or a Hall sensor.

[0068] In particular, cargo scooters which have to comply with increased safety regulations due to the goods or persons being transported or due to possible approval regulations can be provided with safety-enhancing redundancy by designing the rear wheel swivel sensor as several sensors of different types.

[0069] In preferred embodiments of the electrically driven cargo scooter, the rear frame part can have a folding opening which, in the long state of the cargo scooter, is closed by an actuating section of the resiliently deflectable rear wheel securing device.

[0070] The actuating section of the resiliently deflectable rear wheel locking device thus advantageously acts as a closing element when the cargo scooter is extended, preventing soiling of the user caused by the rear wheel interacting with the surface being traveled on. At the same time, the rear wheel locking device functions integrally as an actuator, which can be actuated by the rear wheel release device, whereby actuation causes a resilient and / or elastic deflection of the rear wheel locking device. The integral functionality of the actuating section of the resiliently deflectable rear wheel locking device, in turn, enables a particularly simple and resource-efficient production of this cargo scooter.

[0071] In exemplary embodiments of the cargo scooter, the actuating section can be formed, for example, by an actuating plate which is formed integrally with the groove element or with the securing projection, and which can in particular be formed with one or more bends.

[0072] In preferred embodiments of the electrically driven cargo scooter, the footboard can have at least one fixing element which is configured to engage with at least one fixing counter element of the rear frame part and to secure or fix the long state of the cargo scooter.

[0073] By having at least one fixing element configured to secure or fix the long state of the cargo scooter with a fixing counter element, the footboard is given integral functions which, on the one hand, stabilize or stiffen the long state, whereby the cargo scooter has improved driving dynamics in the long state, and, on the other hand, in particular prevent the cargo scooter from accidentally changing into the short state while a user is standing on the footboard.

[0074] In exemplary embodiments, the at least one fastening element can be designed as a rod element configured to engage in a fastening recess, such as a groove as a fastening counter-element, in a clamping or pre-tensioned manner. In alternative embodiments, the at least one fastening element can be groove-shaped, and the fastening counter-element can be rod-shaped, although further deviating embodiments are also possible. For example, the optionally rod-shaped fastening element or fastening counter-element can be a metal rod, in particular a stainless steel rod or aluminum rod, which has, for example, a round, oval, or any desired polygonal shape.

[0075] In further preferred embodiments of the cargo scooter, the rear wheel release device can have a sliding element or rolling element, which is preferably arranged at its distal end facing away from the footboard.

[0076] Advantageously, the arrangement of a sliding element or rolling element on the rear wheel release device makes it easier to fold the footboard, in particular by supporting the rear frame part by means of a ramp section.

[0077] In addition, the arrangement of a sliding element or rolling element on the rear wheel release device enables the actuation of the resiliently deflectable rear wheel securing device to be carried out with particularly low wear, which increases or improves the longevity and reliability of the cargo scooter as a whole.

[0078] Another electrically driven cargo scooter according to the claimed invention comprises: a front axle with at least one front wheel, wherein the front axle is arranged on a front frame part, and wherein the at least one front wheel is pivotably arranged on the front frame part; a rear axle with at least one rear wheel, wherein the rear axle is arranged on a rear frame part; -- wherein the cargo scooter has a short state in which one of the rear frame part and the front frame part is at least partially arranged in the other of the rear frame part and the front frame part; characterized in that -- in the short state of the cargo scooter, the pivotability of the at least one front wheel is restricted, in particular blocked, preferably mechanically blocked.

[0079] The aforementioned electrically driven cargo scooter(s) as well as their preferred, exemplary and alternative embodiments equally relate to the present electrically driven cargo scooter.

[0080] The limited pivotability of at least one front wheel of the cargo scooter advantageously increases the steerability for a user, in particular when pushing the cargo scooter, similar to pushing a shopping cart, and thereby increases the maneuverability of the cargo scooter in the short state, such as in particular for transport within buildings or to turn the cargo scooter.

[0081] In exemplary embodiments of the cargo scooter, it can have exactly two front wheels, which are arranged spaced apart from one another in a width direction along the front axle, so that the restricted or blocked pivotability enables, in particular, a rotation of the cargo scooter in the short state around the front axle center as the center of rotation. This advantageously allows a particularly small or tight turning circle for the cargo scooter. The rotation of the cargo scooter can be further promoted, in particular, by simultaneously enabling the pivotability of at least one rear wheel, as already described above.

[0082] The pivotability of a front wheel means in particular the ability of the front wheel to rotate about its vertical axis or an axis about which the front wheel is rotatably mounted for a steering movement.

[0083] In exemplary embodiments, the pivotability of at least one front wheel, in particular two front wheels, can be restricted or blocked by a steering blocking section of the rear frame part restricting or blocking a forward-backward movement or a longitudinal movement of a handlebar in the short state of the cargo scooter, in particular by restricting or blocking it by a mechanical stop.

[0084] In further exemplary embodiments, the cargo scooter can in particular have a steering device, wherein an actuatable locking element is arranged on the steering device, which is configured to fix the short state of the cargo scooter when actuated.

[0085] The actuatable locking element can, in particular, be a rod-shaped locking element, which, when actuated, is configured to engage a locking recess in the frame part on which the steering device is not arranged. The locking element can, in particular, be elongated and have a round, oval, cuboid, rectangular, or other polygonal cross-section. The locking recess in the frame part can, in particular, have a shape complementary to the locking element and form a clearance fit, transition fit, or interference fit with the locking element.

[0086] In In exemplary embodiments, the actuatable locking element can be accommodated in sections in the steering device and held in a specific position of the steering device by means of a spring element, such as a spring pin, and / or by means of a lever.

[0087] In In preferred embodiments of the electrically driven cargo scooter, the pivotability of the at least one front wheel in the short state of the cargo scooter can be limited to a range of approximately 0° to approximately 5°, preferably limited to a range of approximately 0° to approximately 2° and particularly preferably completely blocked.

[0088] By restricting the swiveling of at least the front wheel, the cargo scooter can be provided with particularly intuitive and easy steering for the user in the short position.

[0089] Further disclosed is an electrically driven cargo scooter, comprising: a running board; The electrically driven cargo scooter is characterized by a footboard sensor configured to emit a signal in a load state of the footboard and / or to emit a signal in a load-relieved state of the footboard; and a cargo scooter control and / or regulation system connected to the footboard sensor, wherein the cargo scooter control and / or regulation system is configured to adapt a drive of the cargo scooter to the load state or the load-relieved state.

[0090] The aforementioned electrically driven cargo scooter(s) as well as their preferred, exemplary and alternative embodiments equally relate to the present electrically driven cargo scooter.

[0091] The footboard sensor advantageously enables a load state and / or a relief state of the footboard to be detected in order to adapt the drive of the cargo scooter to the state accordingly, so that, for example, the torque provided by the drive is reduced in a relief state, limited to a predetermined value or reduced to zero, or, for example, the torque to be provided by the drive is only released from a certain load state up to a predetermined value or completely.

[0092] The cargo scooter control and / or regulation system can, in particular, comprise a memory module in which limit values ​​can be entered or specified, which define the unloaded state and / or the loaded state. The loaded state can, for example, be defined by the weight of a user, so that drive torque is only released when the footboard is at least loaded with the weight of a predetermined user. This advantageously allows the cargo scooter to be automatically braked as soon as the user leaves the footboard, due to an intentional or unintentional dismount.

[0093] This further offers the advantageous possibility of a certain degree of theft protection or helps prevent misuse by only releasing a drive torque within a specific weight range adapted to the predetermined user, and otherwise limiting it or, for example, reducing it to zero. In preferred embodiments of the electrically driven cargo scooter, the footboard sensor can comprise a weight sensor which detects the loading state or unloading state of the footboard at and / or below a predetermined weight, and / or the footboard sensor can comprise a proximity sensor which detects the loading state or unloading state of the footboard at a predetermined approach position of the footboard and / or in the absence of a predetermined approach position, resulting from a loading or unloading of the footboard.

[0094] In further exemplary embodiments, the footboard sensor may include a plurality of weight sensors and / or a plurality of proximity sensors.

[0095] The footboard sensor enables the loading state and / or the unloading state to be detected accurately and independently of one another by means of the one weight or proximity sensor or by means of the multiple weight and / or proximity sensors, and that, with regard to possible safety aspects, a redundant system can be provided for detecting whether one or more users are on the footboard of the cargo scooter.

[0096] Further disclosed is an electrically driven cargo scooter comprising: a front axle with at least one front wheel, wherein the front axle is arranged on a front frame part; and a rear axle with at least one rear wheel, wherein the rear axle is arranged on a rear frame part; -- wherein the cargo scooter has a short state in which one of the rear frame part and the front frame part is arranged at least partially within the other of the rear frame part and the front frame part; characterized in that When the cargo scooter is in the long position, the rear frame part and the front frame part are configured to support each other at points spaced apart from each other in the longitudinal direction of the cargo scooter.

[0097] The aforementioned electrically driven cargo scooter(s) as well as their preferred, exemplary and alternative embodiments equally relate to the present electrically driven cargo scooter.

[0098] In particular, the rear frame part and the front frame part can be configured to support each other at points spaced apart from each other in the longitudinal direction of the cargo scooter, so that in other words, in the long state of the cargo scooter, both the rear frame part is supported on the front frame part and the front frame part is supported on the rear frame part, wherein the respective support points are preferably spaced apart from each other in the longitudinal direction.

[0099] By supporting the rear frame section and the front frame section at points spaced apart in the longitudinal direction of the cargo scooter when the cargo scooter is in its long position, a very rigid cargo scooter is provided which supports the weight of a user on the footboard without any of the frame sections noticeably sinking for the user and possibly unsettling the user.

[0100] Advantageously, the mutual support of the rear frame part and the front frame part enables the frame parts to form a structure that stiffens one another and prevents the cargo scooter from buckling in the long state, while ensuring that the frame parts can be moved relative to one another in order to convert the cargo scooter into the short state, provided that no fixing element fixes the long state.

[0101] In preferred embodiments of the electrically driven cargo scooter, one of the front frame part and the rear frame part may have a gripping portion, and the other of the front frame part and the rear frame part may have a grippable portion, wherein the gripping portion is configured to rotatably grip the grippable portion, and a support portion may support the front frame part and the rear frame part against twisting.

[0102] In exemplary embodiments of the electrically driven cargo scooter, the rear frame part may have a gripping portion, and the front frame part may have a grippable portion, wherein the gripping portion is configured to rotatably grip the grippable portion, and a support portion may support the front frame part and the rear frame part against twisting.

[0103] In alternative embodiments of the electrically driven cargo scooter, the front frame part may have a gripping portion, and the rear frame part may have a grippable portion, wherein the gripping portion is configured to rotatably grip the grippable portion, and a support portion may support the front frame part and the rear frame part against twisting.

[0104] By configuring the frame parts by means of the gripping section, which is configured to rotatably grip the grippable section, and a support section that supports or secures the frame parts against rotation, in particular rotation about the width direction of the cargo scooter, a plurality of degrees of freedom is advantageously provided to safely transfer the frame parts into the extended state. At the same time, a self-defining alignment of the frame parts relative to one another in the extended state is ensured when rotation of one frame part is permitted until support at the support section between the frame parts is achieved.

[0105] The mutually stiffening configuration of the front frame part and the rear frame part further advantageously enables high driving dynamics, especially when driving at comparatively high speeds, such as on the road.

[0106] In preferred embodiments of the electrically driven cargo scooter, the gripping section can act integrally as a safeguard against detachment of the rear frame part from the front frame part in the forward-backward direction.

[0107] In other words, the gripping section can, in particular, form a stop that prevents further separation or detachment of the rear frame part from the front frame part during the transition to the extended state of the cargo scooter. Thus, the gripping section represents, in particular, an element that defines the extended state of the cargo scooter by preventing further mutual displacement of the frame parts in a direction that separates them.

[0108] In preferred embodiments of the electrically driven cargo scooter, the spaced-apart sections can have a distance of at least about 6 cm to about 15 cm.

[0109] A distance of approximately 6 cm to approximately 15 cm between the spaced-apart sections on which the front frame part and the rear frame part are supported advantageously ensures sufficient stiffening of the cargo scooter in the long state, while the space required for elements that form the support is advantageously kept small.

[0110] In alternative embodiments, the spaced sections may have a distance that differs from the aforementioned range, which, however, would have to be compensated for by a corresponding material-intensive stiffening of the front frame part and the rear frame part.

[0111] Further disclosed is an electrically driven cargo scooter comprising: a front axle with at least one front wheel; a rear axle with at least one rear wheel; and a link for pivoting one of the at least one front wheel or the at least one rear wheel; The electrically driven cargo scooter is characterized by a steering assistance system configured to assist pivoting of the at least one front wheel and / or the at least one rear wheel by applying a pivoting torque to the at least one front wheel and / or the at least one rear wheel by means of a local motor.

[0112] The aforementioned electrically driven cargo scooter(s) as well as their preferred, exemplary and alternative embodiments equally relate to the present electrically driven cargo scooter.

[0113] The steering assistance provides a particularly ergonomic and easy steering of the cargo scooter for a user.

[0114] The pivoting torque can be applied by means of a local motor, particularly in addition to the drive torque, but can also be applied without a drive torque already being applied to the wheel in question—in other words, it can be applied independently of the drive torque being applied, such as when pushing the cargo scooter in a short-term position. The pivoting torque can have either a positive or a negative sign.

[0115] In preferred embodiments, the steering assistance can apply a pivoting torque without a servo motor or a hydraulic motor.

[0116] In exemplary embodiments, each wheel on a front or rear axle comprising multiple wheels can be connected or provided with a local motor, so that during a steering operation, the local motor of the outside wheel applies an additional pivoting torque, in addition to the drive torque, which is directed in the same direction as the drive torque. Additionally or alternatively, during a steering operation, the local motor of the inside wheel can apply an additional pivoting torque, in addition to the drive torque, which is directed opposite to the drive torque, thereby advantageously amplifying the steering movement or cornering movement of the cargo scooter.

[0117] In exemplary embodiments, the local motor may be a wheel hub motor that applies both a drive torque and a pivoting torque to the respective wheel.

[0118] In other words, the local motor, such as a wheel hub motor in particular, can rotate or drive an outside wheel faster than an inside wheel. Furthermore, the local motor can rotate an inside wheel slower than an outside wheel or rotate the inside wheel in the opposite direction of the outside wheel, in order to assist the user during the steering process.

[0119] In preferred embodiments of the electrically driven cargo scooter, the electrically driven cargo scooter can further comprise an angle sensor, wherein the steering assistance is configured to apply the pivoting torque in dependence on a signal from the angle sensor.

[0120] Advantageously, the angle sensor enables the pivoting moment to be applied by the steering assistance depending on the user's steering angle, so that the user is supported appropriately when steering or cornering, so that even particularly tight corners can be negotiated by the user of the cargo scooter without the need for maneuvering.

[0121] In exemplary embodiments, the angle sensor is connected to a cargo scooter control and / or regulation system, wherein the angle sensor sends a steering angle signal to the cargo scooter control and / or regulation system based on the measured angle of the steering angle.

[0122] The cargo scooter control and / or regulation system can send a steering assistance command to the steering assistance, which causes the local motor to apply a pivoting torque to the respective wheel. The steering assistance can form a functional component of the cargo scooter control and / or regulation system or form a control or regulation section of the local motor.

[0123] In preferred embodiments of the electrically driven cargo scooter, the electrically driven cargo scooter may further comprise a load holder, wherein the load holder is preferably arranged in front of a handlebar, and wherein the load holder is configured to interchangeably hold a cargo box and / or a passenger cell.

[0124] The load holder can be positioned, particularly in the forward direction of travel, in front of the handlebars or in front of a steering device. This advantageously allows the user to always estimate the space required while the cargo scooter is moving, while also maintaining an overview of the goods or person being transported.

[0125] Because the cargo holder can interchangeably hold a cargo box and / or a passenger cell, this cargo scooter can cover a variety of suitable application scenarios, such as the transport of children, sick people or other persons, as well as the transport of food, non-food items, other goods and in particular parcels.

[0126] In exemplary embodiments, the load holder may have a thermally insulating cooling receptacle in order to place cooling elements, such as ice packs, underneath a load box in order to be able to cool certain goods.

[0127] Additionally or alternatively, the load holder may have a heating element and / or cooling element or a power connection for connecting, for example, a heating element and / or cooling element, so that persons and goods can be transported at a temperature that is comfortable for them or, if necessary, required.

[0128] In preferred embodiments of the electrically driven cargo scooter, the electrically driven cargo scooter may further comprise an actuatable locking element which is configured to releasably lock the front frame part and the rear frame part to one another in a short state and / or a long state of the cargo scooter.

[0129] The actuatable locking element can in particular be a substantially rod-shaped locking element which, when actuated, is configured to engage in a locking recess in order to releasably lock the front frame part and the rear frame part to one another.

[0130] In exemplary embodiments, the actuatable locking element can be arranged on the front frame part and, by engaging in a locking recess formed or arranged on the rear frame part, can releasably lock the front frame part to the rear frame part. However, the configuration of the cargo scooter with regard to the locking element is not limited to this, so that the locking element and the locking recess can also be arranged on the other of the front frame part and the rear frame part.

[0131] The locking recess can in particular be arranged on the front frame part or rear frame part in such a way that engagement of the locking element therein is only possible when the long state or the short state is reached in a defined manner, such as by a gripping section which cooperates with a grippable section and restricts or limits a releasing movement of the front frame part and the rear frame part that goes beyond a long state.

[0132] In preferred embodiments, the actuatable locking element can be accommodated in sections in a steering device of the cargo scooter and held at a specific position of the steering device by means of a spring element, such as a spring pin, and / or by means of a lever.

[0133] This advantageously allows the user to visually and / or haptically determine whether the cargo scooter's long position is correctly locked or secured. Furthermore, by at least partially integrating the actuatable locking element into the steering mechanism, the cargo scooter has an intuitive, slim, and space-saving configuration.

[0134] For example, at least one lamp and / or a display can be arranged on the steering device. The at least one lamp and / or the display can, in particular, be configured to reproduce or display a signal, such as an electrical signal sent by a sensor or a cargo scooter control and / or regulation system, as a light signal, optical signal, warning, text message, or the like.

[0135] In further exemplary embodiments, the locking recess may have an insertion bevel, such as a ramp and / or a conical opening, to facilitate insertion of the locking element into the locking recess.

[0136] In preferred embodiments of the electrically driven cargo scooter, the footboard can be held pivoted substantially vertically in a short state of the cargo scooter, and / or in a long state of the cargo scooter be held substantially horizontally, wherein the footboard can preferably be held magnetically in the short state and / or in the long state.

[0137] In alternative embodiments, the footboard can be held in a direction deviating from a vertical direction in the short state of the cargo scooter and / or in a direction deviating from a horizontal direction in the long state of the cargo scooter.

[0138] Due to the foldability and pivotability of the footboard, the cargo scooter can be provided in a geometry that is particularly space-saving when in its short state, and this also enables the cargo scooter to use available routes in buildings, such as elevators, corridors, doors and rooms, as transport routes that can be covered with the cargo scooter.

[0139] In addition, for example, the rear frame part can be pushed into the front frame part at least in sections when the cargo scooter is in the short state, whereby the folding or pivoting ability of the footboard means that the footboard does not have to be pushed in when the cargo scooter is in the short state, whereby the front frame part can be designed in an advantageous space-saving and thus also resource-saving manner, since the footboard is preferably wider than the rear frame part to ensure safe pedaling by the user.

[0140] In exemplary embodiments, the rear frame part can be inserted into the front frame part by a length that corresponds to about 0.7 times to about 0.9 times the length of the running board.

[0141] Furthermore, the foldability and pivotability of the footboard means that when the cargo scooter is in the long position, an advantageously wide footboard is provided for the user, which enables the user to sit or stand securely while the cargo scooter is moving. However, when the cargo scooter is in the short position, this has no influence on the space-saving configuration for the cargo scooter, for example for transport in buildings.

[0142] By providing magnetic holders for the footboard in the short and / or long state, a passive footboard holding system is advantageously provided, which is particularly low-wear.

[0143] In addition or instead, the footboard can be held or fixed in the long position and / or in the short position mechanically, for example by means of latches, wedges or by means of a lock.

[0144] In In preferred embodiments of the electrically driven cargo scooter, the electrically driven cargo scooter may further comprise a seating device, wherein the seating device is preferably a height-adjustable seat element and / or a seat element that can be tilted relative to a longitudinal direction of the cargo scooter.

[0145] By providing a preferably adjustable seat, particularly ergonomic and safe movement using the cargo scooter can be ensured.

[0146] In In exemplary embodiments, the seating device may include a securing device, such as a buckle belt, for securing the user and / or a passenger.

[0147] Furthermore, a cargo scooter control and / or regulation system for a cargo scooter for controlling and / or regulating a drive and / or steering assistance of an electrically driven cargo scooter according to one of the preceding electrically driven cargo scooters or according to one of the preceding preferred, alternative and exemplary embodiments is disclosed.

[0148] The cargo scooter control and / or regulation system can in particular be connected directly or indirectly to a plurality of sensors and be configured, on the basis of a sensor signal: to enable, limit, or deny torque for driving the cargo scooter; and / or to issue a steering assistance command to a steering assistance system to apply a pivoting torque to one of the wheels to assist steering or cornering; and / or to enable, limit, or interrupt the flow of current to an electric motor.

[0149] Furthermore, the cargo scooter control and / or regulation system can be configured to display the states detected by the sensors. The display of the detected states can be done, in particular, using one or more lamps and / or a display. The display or reproduction of a signal can, for example, include or be a light signal, a visual signal, a warning, a text message, or the like.

[0150] The aforementioned electrically driven cargo scooter(s) as well as their preferred, exemplary and alternative embodiments equally relate to the present cargo scooter control and / or regulation system.

[0151] The present cargo scooter control and / or regulation system advantageously enables the cargo scooter according to the invention to be controlled and / or regulated in an ergonomic manner.

[0152] In exemplary embodiments, the cargo roller may include a display connected to the cargo roller control and / or regulation system and configured to display and / or select various controlling and / or regulating functions to or for the user.

[0153] Furthermore, the cargo scooter control and / or regulation system can comprise a transmitter and / or receiver that allows remote control of the cargo scooter using an external device that includes a corresponding transmitter. The cargo scooter control and / or regulation system can, in particular, comprise a Bluetooth, RFID, UMTS, or other radio transmitter or receiver.

[0154] In addition, the cargo scooter control and / or regulation system may in particular comprise a processor, a memory module and / or a computer to process signals, send commands to the drive and other peripherals of the cargo scooter and execute routes or computer programs.

[0155] Furthermore, a method for controlling and / or regulating an electrically operated cargo scooter is disclosed, comprising the steps: Querying at least one of the footboard sensor, the rear wheel pivot sensor, and the angle sensor according to any one of the preceding aspects or embodiments; and controlling at least one of a drive torque and / or a pivot torque in response to the sensor query.

[0156] The aforementioned electrically driven cargo scooter(s) as well as their preferred, exemplary and alternative embodiments equally relate to the present method for controlling and / or regulating an electrically driven cargo scooter.

[0157] Furthermore, a computer program product is disclosed, comprising instructions which, when the computer program product is executed by a computer, cause the computer to carry out the method for controlling and / or regulating an electrically operable cargo scooter.

[0158] The aforementioned electrically driven cargo scooter(s) as well as their preferred, exemplary and alternative embodiments equally relate to the present computer program product.

[0159] In the following, embodiments of the invention are described in more detail with reference to the accompanying figures. It is understood that the present invention is not limited to these embodiments and that individual features of the

[0160] Embodiments can be combined to form further embodiments within the scope of the appended claims.

[0161] It shows: Figure 1 shows a perspective view of a cargo scooter according to the invention; Figure 2 shows a perspective view of a cargo scooter according to the invention from below; Figure 3 shows a sectional view of a cargo scooter according to the invention; Figure 4 shows a perspective view of a cargo scooter according to the invention with a footboard not shown; and Figure 5 shows a perspective view of a footboard of a cargo scooter according to the invention; and Figure 6 shows a further sectional view of a cargo scooter according to the invention.

[0162] Fig. 1 shows an exemplary embodiment of a cargo scooter 1 according to the invention in a perspective view. Fig. 1 shows the cargo scooter 1 in a particularly long state. As in Fig. 1 As shown by way of example, the cargo scooter 1 can in particular have a seating device 80 and a footboard 70, so that a user can ride the cargo scooter 1 while sitting or standing.

[0163] How to continue in Fig. 1 As shown, the cargo scooter can, for example, have a front axle which is arranged on a front frame part 10 of the cargo scooter 1, and a rear axle which is arranged on a rear frame part 50 of the cargo scooter 1. Two front wheels 20 can, for example, be arranged on the front axle. A single rear wheel 60 can, for example, be arranged on the rear axle. However, the cargo scooter 1 according to the invention is not limited to this, so that in alternative embodiments, for example, two rear wheels 60 can be arranged on the rear axle and a front wheel 20 can be arranged on the front axle, or two wheels can be arranged on each of the front axle and the rear axle. Furthermore, the respective wheels can also be designed as twin wheels.

[0164] How to continue in Fig. 1 As can be seen, the cargo scooter 1 can in particular have a container 12, which can, for example, be arranged or fixed to the front frame part 10. The container 12 can in particular be arranged or fixed in the longitudinal direction I on a side of the front frame part 10 facing the user, in particular when the user is standing on the footboard 70.

[0165] The container 12 can in particular be configured to accommodate one or more replaceable batteries in order to prepare the cargo scooter 1 for covering a greater distance, which saves time, especially compared to charging via a socket.

[0166] The container 12 may in particular be a lockable container 12 which is provided with an opening and optionally with a flap or a lid, which is preferably closed by means of a lock 14, as in Fig. 2 indicated, can be locked on the container 12 against opening.

[0167] As continued in Fig. 1 As shown, the cargo scooter 1 can have a steering device 30, which extends at least in sections substantially upwards or in the vertical direction h. The steering device 30 can have a handlebar 34 at its upper end or at its upper end in the vertical direction h, which allows the user to steer the cargo scooter 1 or enables the cargo scooter 1 to corner based on a steering angle by the user. As shown in Fig. 1 As indicated by way of example, the handlebar 34 can be designed similarly to a bicycle or motorcycle handlebar, thereby enabling a user to control the cargo scooter 1 in a particularly intuitive manner. The handlebar 34 can in particular comprise one or more brake control elements, such as a brake lever, one or more drive control elements, such as a thumb throttle, one or more signal control elements, such as a horn or bell, one or more lighting control elements, one or more displays, and / or one or more input or control elements suitable for acoustic and / or tactile input or operation, such as a microphone, touch display and / or a keyboard.

[0168] As in Fig. 1 As shown, the steering device 30 can comprise a handlebar inclination adjustment 36, by means of which the inclination of a section of the steering device 30 above the handlebar inclination adjustment 36 or the inclination of the handlebar 34 relative to the longitudinal direction I, or in a plane spanned by the longitudinal direction I and the height direction h, can be set or adjusted. This enables the user to advantageously ergonomically adjust or set the handlebar 34. Additionally or alternatively, the steering device 30 can have a handlebar height adjustment, which allows the handlebar 34 to be adjusted or set along the steering device 30, for example in the height direction h, which likewise enables the user to advantageously ergonomically adjust the handlebar 34.

[0169] Equally, although in Fig. 1 not shown, the seat device 80 can, for example, have a seat height adjustment and / or a seat inclination adjustment in order to enable a user to sit or support themselves ergonomically on the cargo scooter 1.

[0170] As finally further in Fig. 1 As shown, in particular, the front frame part 10 can comprise a load holder 11, which can be configured in particular to hold a load box and / or a passenger compartment (both not shown). The load holder 11 can preferably comprise rail elements and / or resilient connecting elements and / or grid elements in order to be able to reversibly fasten load boxes and / or passenger compartments thereto, as well as to fasten load boxes and / or passenger compartments of a third-party design by means of straps or belts. As shown in Fig. 1 As shown, the load holder 11 can be formed in particular between two front wheels 20, so that the cargo scooter 1 has an advantageously low center of gravity when loaded, which in turn advantageously improves driving stability, while the front wheels 20 can simultaneously have a large wheel diameter, whereby the front wheels 20, and thus the cargo scooter 1, are or become advantageously insensitive to unevenness.

[0171] Fig. 2 shows a further perspective view of an embodiment of a cargo scooter 1 according to the invention, but essentially from an underside. Fig. 2 represents a cargo scooter 1 in a long state. As in Fig. 2 As can be seen, the cargo scooter 1 can in particular have a front frame part 10 and a rear frame part 50, wherein the front frame part 10 has received the rear frame part 50 in sections. The rear frame part 50 and the front frame part 10 can be configured to be displaceable relative to one another, in particular configured to be displaceable relative to one another along the longitudinal direction I. While the long state of the cargo scooter 1 is a state in which the rear frame part 50 is in particular pulled out or extended from the front frame part 10 to the maximum, i.e. up to an end point or stop, a short state of the cargo scooter 1 can, in contrast, be a state in which the rear frame part 50 is pushed into or received in the front frame part 10 to the maximum, i.e. up to another end point or another stop.The partial reception of the rear frame part 50 in the front frame part 10 should not be understood to mean that a section of the rear frame part 50 is completely, i.e., entirely, surrounded by the front frame part 10. Rather, the rear frame part 50 can be received in the front frame part 10 in such a way that the received part of the rear frame part 50 is only partially or partially surrounded by the front frame part 10. In alternative embodiments, i.e., not as in . Fig. 2 As shown, the front frame part 10 can also be accommodated at least partially in the rear frame part 50, or the rear frame part 50 and the front frame part 10 can each engage with one another in sections or surround one another in sections. Alternatively, the front frame part 10 and the rear frame part 50 can be arranged separately from one another and, for example, can be displaced past one another.

[0172] How to continue in Fig. 2 As can be seen, the extended state of the cargo scooter 1 can be characterized in particular by the fact that the footboard 70 is in a ready-to-use state for a user. In other words, the extended state of the cargo scooter 1 can be characterized by the fact that the footboard 70 is positioned on the cargo scooter 1 in such a way that a user can stand on it. The footboard 70 can run essentially horizontally or be inclined relative to a surface of the cargo scooter 1.

[0173] As in Fig. 2 As shown, in the long state of the cargo scooter 1, the footboard 70 can be supported or fastened to the front frame part 10 with a front section in the longitudinal direction I and can be supported or fastened to the rear frame part 50 with a rear section in the longitudinal direction I, whereby the footboard 70, in addition to the function of providing a safe step for the user, acts integrally as a relative fixing or fixation of the rear frame part 50 to the front frame part 10.

[0174] As can be seen from the Figuren 1 and 2 As can be seen, the running board 70 is generally arranged above the rear frame part 50, and in particular in the long or ready-to-drive state, or is supported by the rear frame part 50 which is located below it at least in sections in the height direction h.

[0175] As in Fig. 2 As shown, in the extended state, a fastening element 72 of the running board 70 can engage with a counter-fastening element 52 of the rear frame part 50. For example, the fastening element 72 can encompass the counter-fastening element 52 at least in sections, in particular clamp it in a clamping manner at least in sections. The fastening element 72 can, for example, comprise or consist of a hard rubber, which facilitates a clamping engagement and simultaneously ensures a damping effect, so that the engagement between the fastening element 72 and the counter-fastening element 52 does not automatically detach, even in the event of vibrations, for example caused by driving on a certain surface.

[0176] Although not in Fig. 2 As shown, the running board 70 can, for example, have two fastening elements 72 opposite one another in the width direction b, which can engage with a corresponding pair of fastening counter-elements 52. Alternatively, the running board 70 can also have any desired plurality of fastening elements 72, which can engage with a corresponding plurality of fastening counter-elements 52.

[0177] As through Fig. 2 As indicated, the footboard 70 can in particular have a greater width in the width direction b than the rear frame part 50, thereby providing a sufficiently large stepping surface for a user, for example with a passenger. Furthermore, the rear frame part 50, in the area in which the footboard 70 is supported on it in the long state, can have a smaller width or a smaller cross-section than the front frame part 10. The cross-section here means in particular a cross-section in the height direction h and in the width direction b of the cargo scooter 1 and is representative of the dimensions of the rear frame part 50 in the height direction h and in the width direction b, which can in particular be smaller than those of the front frame part 10. This makes it possible for the footboard 70 to be folded up or folded down.By pivoting the footboard 70 upwards, the rear frame part 50 can be pushed into the front frame part 10, in particular with a length in the range of approximately 0.7 times to approximately 0.9 times that of the footboard 70 into the front frame part 10. This advantageously makes it possible for the present cargo scooter 1 to be operated in a long state and in a short state, which is significantly shorter than the long state, so that the present cargo scooter 1 is suitable for riding in the long state, in particular on roads and cycle paths, while the short state is suitable for pushing, in particular in buildings.

[0178] The pivoting or folding up of the footboard 70 can be carried out in particular around a joint receptacle 16, which receives a joint part 76 of the footboard 70, as in Fig. 3 better shown.

[0179] How to continue in Fig. 2 As shown, one or more brackets 32 may be arranged on the container 12 and / or on the steering device 30 to hold the footboard 70 in the folded or upwardly pivoted state. The brackets 32 are in Fig. 2 only schematically sketched and can in particular comprise magnets, grippers, fitting pieces or the like, which hold the folded-up or upwardly pivoted footboard 70 magnetically or mechanically, and form with the folded-up or upwardly pivoted footboard 70, for example, a push-push system or a push-pull system.

[0180] As continued in Fig. 2 As shown, one or more locks 14 can be arranged on the container 12, which enable secure locking of the container 12. This allows valuables belonging to a user 12, as well as interchangeable elements such as batteries or tokens for user identification, to be securely protected from theft.

[0181] How to continue in Fig. 2 As shown, the rear frame part 50 can have a folding opening 56. The folding opening 56 can be arranged, in particular, in the vertical direction h above the rear wheel 60. The folding opening 56 forms, in particular, an opening that connects a region in which the rear wheel 60 is arranged, i.e., substantially below the rear frame part 50, and a region in which the footboard 70 is arranged, i.e., substantially above the rear frame part 50.

[0182] The folding opening 56 is configured in particular by a rear wheel release device 74, in particular by a rolling element of the rear wheel release device 74, which is arranged on the footboard 70 and in Fig. 3 can be better seen. The folding opening 56 can preferably be passed through by the rear wheel release device 74 when the cargo scooter 1 enters a short state or shortly before reaching the short state, and when the footboard 70 is in a folded-up or pivoted state, i.e., in a non-drivable state.

[0183] In the extended state of the cargo scooter 1, the folding opening 56 can be closed, in particular, by a resiliently deflectable rear wheel securing device 62, in particular by an actuating section 64 of the resiliently deflectable rear wheel securing device 62. In the extended state of the cargo scooter 1, the resiliently deflectable rear wheel securing device 62 or its actuating section 64 can, in particular, be configured to at least partially adjoin, rest against, or touch the section of the rear frame part 50 surrounding the folding opening 56. This advantageously prevents dirt from the rear wheel 60 from being thrown through the folding opening 56 and possibly toward the user in the extended state of the cargo scooter 1.

[0184] Further details of the resiliently deflectable rear wheel securing device 62 are shown in the sectional view in Fig. 3 which shows a perspective view of a section along the height direction h and the longitudinal direction I of the cargo scooter 1.

[0185] Fig. 3 shows the resiliently deflectable rear wheel securing device 62 in a deflected position to illustrate its function. In other words, Fig. 3 the resiliently deflectable rear wheel securing device 62 in a position which the resiliently deflectable rear wheel securing device 62 assumes when it is deflected or actuated by the rear wheel release device 74. At the same time, Fig. 3 the rear wheel release device 74 with the footboard 70 in a ready-to-drive position of the footboard 70. In other words, the rear wheel release device 74 is in Fig. 3 However, it is shown in a position in which it does not yet actuate the resiliently deflectable rear wheel locking device 62. This is intended solely for clarity.

[0186] If only the rear wheel securing device 62 is referred to below, this should always be understood as the resiliently deflectable rear wheel securing device 62.

[0187] As in Fig. 3 in the area of ​​the rear wheel 60, the rear wheel securing device 62 can in particular have a groove element 66 which is configured to engage with a securing projection 67 in a non-deflected state of the rear wheel securing device 62, so that the pivotability of the rear wheel 60, i.e. the rotatability of the rear wheel 60 about a vertical axis HA, is restricted or blocked depending on the design of the engagement between the groove element 66 and the securing projection 67.

[0188] As in Fig. 3 As shown, the securing projection 67 can be arranged on the rear wheel 60 or connected thereto. The rear wheel 60 can in particular be arranged on a rear wheel suspension 61 or fastened thereto, wherein the rear wheel suspension 61 is preferably mounted on the rear frame part 50 so as to be rotatable about a vertical axis HA in order to fundamentally enable pivoting of the rear wheel 60. The vertical axis HA can, for example, run approximately parallel to the vertical direction h of the cargo scooter and thereby enable pivoting of the rear wheel 60 in a plane perpendicular to the vertical axis HA, spanned approximately by the longitudinal direction I and the width direction b of the cargo scooter 1.

[0189] The securing projection 67 is preferably arranged on the wheel suspension 61. The rear wheel securing device 62 is preferably resiliently mounted on the rear frame part 50. The rear wheel securing device 62 is preferably pretensioned such that it or an actuating section 64 arranged on it, in the extended state of the cargo scooter 1, presses against the section of the rear frame part 50 surrounding the folding opening 56 and closes the folding opening 56. The groove element 66 can, for example, as shown in Fig. 3 indicated, be formed integrally on the rear wheel securing device 62, or be fixed thereto, so that a deflection of the actuating section 64 of the rear wheel securing device 62 causes a deflection of the groove element 66 of the rear wheel securing device 62. As in Fig. 3 As indicated, the rear wheel securing device 62 can be mounted on the rear frame part 50 in a resiliently rotating manner, so that a rotational deflection of the actuating section 64, in particular by means of the rear wheel release device 74, which passes the folding opening 56, causes a rotation of the groove element 66 and releases an engagement between the groove element 66 and the securing projection 67, whereby the pivotability of the rear wheel 60 is released.

[0190] As in Fig. 3 As shown, the center point of the rear wheel 60 and the securing projection 67 can preferably be arranged on the rear wheel suspension 61 such that they are arranged on the same side with respect to the vertical axis HA and each spaced apart from the vertical axis HA. This advantageously enables the rear wheel 60, when traveling backwards or rearward, to assume a position in which the rear wheel 60 assumes a substantially straight orientation along the longitudinal direction I and the center point of the rear wheel 60 is arranged further forward in the longitudinal direction I relative to the vertical axis HA. In order to be easily actuated by the rear wheel release device 74 of the footboard 70, the rear wheel release device 74 is also arranged further forward in the longitudinal direction I than the vertical axis HA of the rear wheel suspension 61 when the cargo scooter 1 is in the short state.This preferred arrangement allows the rear wheel securing device 62 to securely engage the securing projection 67 starting from a short state of the cargo scooter 1 and transitioning the cargo scooter 1 to the long state.

[0191] This ensures an advantageously safe and easy transition of the cargo scooter 1 from a short state to a long state for the user, wherein the short state in particular enables transport routes which may be in buildings, for example by pushing the cargo scooter, and the long state enables journeys at higher speeds, for example on roads.

[0192] In exemplary embodiments, the cargo scooter 1 may comprise a cargo scooter control and / or regulation system that enables the user to execute or have executed a transition routine for transitioning the cargo scooter 1 from the short state to the long state, wherein the short state is left and the long state is reached by preferably moving the rear wheel 60 backwards or rearwards in the direction of travel and particularly preferably by locking the front wheel 20 or the front wheels 20 while the rear wheel 60 is moved backwards in the direction of travel.

[0193] How to continue in Fig. 3 As shown, a rear wheel pivot sensor 94 for detecting whether the groove element 66 and the securing projection 67 are engaged can be arranged on the rear frame part 50 or preferably on the rear wheel securing device 62. In exemplary embodiments, the rear wheel pivot sensor 94 can, in particular, be a proximity sensor. Furthermore, the rear wheel pivot sensor can, in particular, be connected to the cargo scooter control and / or regulation system, for example, to limit or prevent the drive of the cargo scooter 1 if the groove element 66 and the securing projection 67 are not engaged, in order to avoid an unstable driving situation with a freely pivoting rear wheel 60.

[0194] How to continue in Fig. 3 As shown, the footboard 70, in particular at its front end in the longitudinal direction I, can be rotatably or pivotably mounted on a joint receptacle 16 of the front frame part 10 by means of a joint part 76 of the footboard 70. The joint part 76, together with the joint receptacle 16, can in particular enable the footboard 70 to rotate or pivot about a transverse axis, which runs essentially in the width direction b of the cargo scooter 1.

[0195] As continued in Fig. 3 As shown, the rear frame part 50 can in particular have a recess for the rear wheel release device 74, which is arranged on the footboard 70, so that the rear wheel release device 74 finds space in the recess and is preferably housed by the rear frame part 50 when the footboard 70 is in a driving position.

[0196] The recess of the rear frame part 50 can partially form a ramp section 44, which is configured to guide the footboard 70 upward during folding or pivoting. Furthermore, the ramp section 44 can provide support for the rear wheel release device 74 during the folding or pivoting of the footboard 70 upward, thereby advantageously facilitating the folding or pivoting of the footboard 70 upward for the user.

[0197] As in Fig. 3 As indicated in the rear region of the footboard 70 in the longitudinal direction I, one or more footboard sensors 90 can be arranged on the rear frame part 50, below the footboard 70. The footboard sensor(s) 90 can, for example, comprise at least one weight sensor 91 and / or at least one proximity sensor. The footboard sensor(s) 90 can, in particular, be configured to detect a load state and, additionally or alternatively, a load-relieving state of the footboard 70. The footboard sensor(s) 90 can, in particular, be connected to a cargo scooter control and / or regulation system, so that upon detection of a load state or a load-relieving state, for example, a drive of the cargo scooter 1 can be prevented, limited, or enabled.

[0198] As continued in Fig. 3 As shown, a locking element 38, in particular an actuatable locking element 38, can be accommodated at least in sections in the steering device 30, which is preferably arranged in the longitudinal direction I in front of the footboard 70. The actuatable locking element 38 can, as in Fig. 3 highlighted, essentially rod-shaped. As is not the case in Fig. 3 As shown, the locking means can preferably be arranged on or in the steering device 30 in a height-adjustable manner by means of an actuatable lever, pin or knob.

[0199] The actuatable locking element 38 is preferably configured to engage in a locking recess 47 in the extended state and / or the short state of the cargo scooter 1, thereby locking or securing the cargo scooter 1 in the respective state. The actuatable locking element 38 preferably engages the locking recess 47 in a releasable manner, whereby the user can preferably use the same actuatable lever, pin, or knob as for locking.

[0200] The locking element 38 can be designed in particular as a steel rod or steel tube, and preferably at least partially accommodated in the steering device 30, which can be designed in particular as a steel tube.

[0201] In preferred embodiments and as in Fig. 3 As shown, the steering device 30, and thus the locking element 38, is arranged or fastened to the front frame part 10, so that for locking a long or short state of the cargo scooter 1, the locking recess 47 is preferably arranged or formed on the rear frame part 50.

[0202] The locking recess 47 can be formed, in particular, by a reinforcing element 46, which is not formed integrally with the frame part on which the locking recess 47 is arranged, but can in particular be a more rigid element than the frame part or comprise or have a more rigid material, such as a steel sheet or a stainless steel sheet. In exemplary embodiments, the front frame part 10 and the rear frame part 50 can comprise or consist of steel or aluminum. The reinforcing element 46 having the locking recess 47 can comprise or be made of a more rigid metal, in particular steel.Furthermore, the reinforcing element 46 having the locking recess 47 can have a guide bevel which prevents an abrupt abutment of the locking element 38 against the reinforcing element 46, in particular if the height-adjustable locking element 38 is set or actuated at an incorrect height, so that wear on the locking element 38 and the associated increasing inaccuracy when locking the front frame part to the rear frame part are advantageously prevented.

[0203] How to continue in Fig. 3 As shown, a locking sensor 92 can be arranged below the one or more locking recesses 47 on the respective frame part to detect whether the locking element 38 is in the locking recess 47. The locking sensor 92 can in particular be an optical sensor or a proximity sensor, wherein Fig. 3 The latter is shown by way of example. The locking sensor 92 for detecting the locking engagement can be connected, in particular, to the cargo scooter control and / or regulation system. This advantageously allows, depending on whether the locking element 38 engages in a locking recess 47 to lock or unlock the short or long state of the cargo scooter 1, in particular, a drive of the cargo scooter 1 can be prevented, limited, or enabled.

[0204] Figur 4 shows a further perspective view of a cargo scooter 1 according to the invention, wherein the footboard 70 is not shown.

[0205] As in Fig. 4 shown, a reinforcing element 46 is arranged on an upper side of the rear frame part 50 and has the locking recess 47 which is configured to engage with the locking element 38 which is in Fig. 3 shown, to intervene. From the overview of the Figuren 3 and 4 It becomes clear that the Fig. 3 and 4The locking recess 47, shown by way of example, and the locking element 38 can engage, in particular, when the rear frame part 50 is pushed forward by a corresponding amount in the longitudinal direction I, along the front frame part 10. The reinforcing element 46 preferably has a guide bevel, so that the reinforcing element 46 is preferably shaped such that it takes up a smaller height, measured in the height direction h, following the longitudinal direction I. As a result, the locking element 38 can advantageously be guided along the guide bevel, even if the locking element 38 is set to a height that is too low to engage in the locking recess 47. As a result, wear and tear on the locking element 38 and on the frame part on which the locking recess 47 is arranged can be reduced or avoided.

[0206] Continue in Fig. 4 The footboard sensor 90 can be seen, which can be, for example, a weight sensor 91, but can also be another sensor, such as an optical sensor, proximity sensor, or contact sensor. The footboard sensor 90 is particularly configured to recognize or detect a load state and / or a load-relieving state of the footboard 70. Preferably, the footboard sensor 90 is connected to the cargo scooter control and / or regulation system. Based on the detection of a load state or a load-relieving state, the cargo scooter control and / or regulation system can, for example, prevent, limit, or enable the drive of the cargo scooter.Furthermore, based on the detection of a load-relief state, in particular, the cargo scooter control and / or regulation system can, for example, activate one or more wheel brakes to reduce the speed of the cargo scooter 1 to zero, in particular after a user and / or a passenger of the user dismounts. Furthermore, the cargo scooter control and / or regulation system can be configured to request a confirmatory input from the user when a load-relief state is detected in order to release or deactivate one or more wheel brakes to enable the user to push the cargo scooter 1.

[0207] Fig. 5 shows an exemplary footboard 70 of a cargo scooter 1 according to the invention. Essentially, an underside of the footboard 70 is visible. The footboard 70 shown can in particular essentially correspond to the footboard 70 as shown in the Figuren 1 bis 3 in the installed state, i.e. arranged on the cargo scooter 1.

[0208] On in Fig. 5 In the region of the running board 70 shown as the upper end, the running board 70 has one or more fixing elements 72 which are particularly configured to engage with fixing counter-elements 52 which are arranged on the rear frame part 50 in order to releasably arrange or releasably fix the running board 70 to the rear frame part 50 in a driving-ready state.

[0209] The determination elements 72 are in Fig. 5 For example, they are groove-shaped, so that they are each configured to at least partially encompass a fastening counter-element 52. However, the fastening elements 72 and the fastening counter-elements 52 are not limited to the shapes shown and can each also have the shape of the other.

[0210] The fixing elements 72 can preferably comprise or consist of hard rubber, whereby a clamping effect and a damping effect advantageously occur or arise upon engagement with the fixing counter-elements 52, which on the one hand enables a secure fixing of the footboard 70, and at the same time enables a stress-relieving effect for the user, since vibrations towards the user stepping onto the footboard 70 are dampened.

[0211] The footboard 70 may further comprise any number of fixing elements 72 which are arranged over the two Fig. 5 illustrated fixing elements 72, or have only a single fixing element 72.

[0212] At the other end of the footboard 70, the footboard 70 preferably has a joint part 76, which is configured to form a pivot joint with a joint receptacle 16, which can be arranged, for example, on the front frame part 10, preferably with a pivot axis in the transverse direction or substantially in the width direction b of the cargo scooter 1. In exemplary embodiments and as in Fig. 5 As shown, the joint part 76 may be substantially rod-shaped.

[0213] How to continue in Fig. 5 As shown, the footboard 70 can have a rear wheel release device 74, which in particular forms a projection relative to an underside of the footboard 70. The rear wheel release device 74 is arranged in particular on the underside of the footboard 70, and is arranged on the footboard 70 in the vicinity of the joint part 76. The rear wheel release device 74 is arranged in particular on the footboard 70 such that the rear wheel release device 74, when the footboard 70 is in a folded-up or upwardly pivoted state, and the cargo scooter 1 is further in a short state, deflects the rear wheel securing device 62 or actuates it such that the pivotability of the rear wheel 60 is released. The rear wheel release device 74 can in particular be configured such that the Figuren 2 and 4to pass through or penetrate the illustrated folding opening 56 in such a way that it deflects an actuating section 64 or an actuating plate of the rear wheel securing device 62 in a rotational manner about a transverse axis, which causes a corresponding deflection or rotation of a groove element 66, whereby the groove element 66 of the rear wheel securing device 62 and a securing projection 67 connected to the rear wheel 60 are disengaged, so that the pivotability of the rear wheel 60 is released.

[0214] As in Fig. 5 As illustrated, the rear wheel release device 74 can in particular have a sliding element and / or a rolling element, thereby enabling particularly gentle or low-wear operation of the rear wheel securing device 62 or of the actuating section 64 of the rear wheel securing device 62. Furthermore, a sliding element and / or rolling element advantageously assists the folding up or upward pivoting of the footboard 70, in particular by supporting it by means of a ramp section 44 on the rear frame part 50, by reducing the force required by the user and simultaneously reducing or minimizing friction between the rear wheel release device 74 and the rear frame part 50.

[0215] Fig. 6 shows a further perspective view of a sectional view of a cargo scooter 1 according to the invention, wherein the section runs essentially along the longitudinal direction I and the height direction h of the cargo scooter 1. Fig. 6 represents, by way of example, the long state of the cargo scooter 1, wherein the front frame part 10 and the rear frame part 50 are in a state in which they are maximally extended relative to one another or pushed apart in the longitudinal direction I.

[0216] As in Fig. 6 As shown, the rear frame part 50 can have a gripping section 58, which has a groove or recess that enlarges counter to the longitudinal direction I of the cargo scooter 1 and is closed in the longitudinal direction I of the cargo scooter 1. The front frame part 10 preferably has a grippable section 18 complementary to the gripping section 58 of the rear frame part 50, which is configured to be gripped by the gripping section 58, in particular to be gripped rotatably.

[0217] Because the gripping section 58 has a groove or recess that increases in size counter to the longitudinal direction I of the cargo scooter 1, secure gripping of the grippable section 18 is advantageously facilitated when the front frame part 10 and the rear frame part 50 move toward the extended state. The rotatable gripping of the grippable section 18 by the gripping section 58 also facilitates the fact that, in addition to the first support point formed by the gripping section 58 and the grippable section 18, a second support point, formed by a support element 19 of the front frame part 10 and a support section 59 of the rear frame part 59, forms itself without exact geometric specifications, advantageously due to the rotational degree of freedom resulting from the first support point, and prevents or blocks further rotation of the front frame part 10 relative to the rear frame part 50.

[0218] The support element 19 is preferably arranged or fastened to the front frame part 10, counter to the longitudinal direction I of the cargo scooter 1, at a distance from the grippable section 18. The support section 59 is preferably arranged or fastened to the rear frame part 50, counter to the longitudinal direction I of the cargo scooter 1, at a distance from the gripping section 58. Consequently, the first support point, consisting of the gripping section 58 and the grippable section 18, and the second support point, consisting of the support element 19 and the support section 59, advantageously form two points or support points spaced apart from one another in the longitudinal direction I, by means of which buckling of the cargo scooter 1, in particular when loaded by a user, is prevented, and the front frame part 10 and the rear frame part 50 additionally support and stiffen one another. In order to reliably ensure mutual support, the two spaced apart points orSupport points are preferably spaced at least approximately 6 cm apart. Depending on the dimensions of the frame parts, smaller distances can also be realized, but this requires the front frame part 10 and the rear frame part 50 to have a greater wall thickness in order to provide a sufficiently rigid cargo scooter 1.

[0219] The gripping portion 58 preferably forms an integral stop with the grippable portion 18, which defines a maximum extension or withdrawal of the rear frame part 50 from the front frame part 10.

[0220] How to continue in Fig. 6 As shown, the front frame part 10 and the rear frame part 50 can be mounted displaceably relative to one another, in particular by means of a rail system 40 Bezugszeichenliste
