Abstract
Description
Technical Field
[0001] The present invention relates to a modular cargo vehicle for transporting cargo by a rider. Background Art
[0002] It is known that bicycles, for example with two or three wheels (tricycles), can be used to transport cargo on a luggage rack. The bicycle can be driven by the rider via a pedal crank. Additionally or alternatively, the bicycle can be driven by means of an electric drive motor. Furthermore, a trailer can be coupled to the bicycle in order to transport relatively large cargo items.
[0003] So-called scooters in English are also known, in which the rider stands essentially upright on a stator and drives the vehicle by pushing one foot against the ground without a pedal crank. It is usually not possible to transport relatively large cargo items on such scooters.
[0004] Motor vehicles are often used to transport relatively large cargo items. However, in addition to the higher driving energy, motor vehicles also require wider access routes than bicycles and scooters.
[0005] The use of a variety of transport vehicles would be particularly efficient and economical, particularly for delivering a very wide range of freight by delivery service, depending on the size and quantity of the freight.
[0006] However, for this purpose a relatively large fleet of vehicles with corresponding parking facilities must be provided. A large proportion of the vehicles will then remain unused at any given time. Summary of the invention
[0007] An object of the present invention is to provide a modular cargo vehicle which can be used in a flexible manner and which allows efficient transport of cargo of varying quantities or sizes in a variety of environments.
[0008] This object is achieved by a modular cargo vehicle for transporting cargo by a rider, wherein the cargo vehicle comprises a towing bicycle, wherein the towing bicycle comprises a front axle with a front wheel and a rear axle with one or two rear wheels, wherein the towing bicycle comprises a rider seat, wherein the towing bicycle can be driven by the rider via pedal cranks, wherein the cargo vehicle comprises a front cargo module, wherein the front cargo module and the towing bicycle are designed such that the rear end of the front cargo module can be coupled to the front end of the towing bicycle, wherein the front cargo module comprises a front axle with a front wheel and includes a cargo receiving area and does not include a rear axle, wherein the cargo vehicle comprises a trailer cargo module, wherein the trailer cargo module and the towing bicycle are designed such that the front end of the trailer cargo module can be coupled to the rear end of the towing bicycle, wherein the trailer cargo module comprises an axle, preferably axially centered, with two wheels and includes a cargo receiving area.
[0009] According to the invention, a traction bicycle is used for transporting goods, which traction bicycle can be driven by the rider via a pedal crank, that is to say a bicycle that can be driven by one person. The bicycle can preferably be designed with three wheels, i.e. a tricycle. The traction bicycle is coupled at the rear to a trailer designed for this purpose and at the front to a front cargo module designed for this purpose, without having their own rear axle. Both the front cargo module and the trailer cargo module are used for transporting goods, in particular cargo items, and therefore have a cargo receiving surface.
[0010] In the context of this document, the expressions "front", "in front" and "in rear" relate to the usual direction of travel of the vehicle. Similarly, the expression "long" relates to the longitudinal extent of the vehicle, i.e. the x-direction, from front to rear, which also usually corresponds to the direction of travel of the vehicle.
[0011] Developments of the invention are specified in the dependent claims, the description and the drawings.
[0012] Preferably, the towing bicycle and the front cargo module are designed so that when the front cargo module is coupled to the towing bicycle, the front wheel of the front axle of the towing bicycle is not in contact with the ground. The rear axle of the towing bicycle can then be driven by the pedal cranks. Alternatively, when the trailer cargo module is coupled to the towing bicycle, one or more rear wheels of the rear axle of the towing bicycle are not in contact with the ground. The front axle of the towing bicycle can then be driven by the pedal cranks.
[0013] Preferably, the traction bicycle has a drive battery and an electric drive motor, and one axle of the traction bicycle can be driven by the electric drive motor, preferably the axle of the traction bicycle can be driven by a pedal crank.
[0014] Preferably, the front cargo module has a drive battery and an electric drive motor, and a front axle of the front cargo module can be driven by means of the electric motor.
[0015] Preferably, the trailer cargo module has a drive battery and an electric drive motor, and an axle of the trailer cargo module can be driven by means of the electric drive motor.
[0016] Preferably, the traction bicycle has a scooter mode, in which the standing surface of the traction bicycle can be used, so that the rider can stand on the standing surface and drive the traction bicycle by pushing off from the road with one foot. The traction bicycle preferably also has a bicycle mode, in which the rider can use the rider seat and pedal cranks, so that the traction bicycle can be driven by the rider by pedaling like a traditional bicycle. In one embodiment of the invention, in the scooter mode, the rider seat and / or the pedal cranks can be moved to a non-use position, for example, the rider seat and / or the pedal cranks can be removed or folded.
[0017] Preferably, the front cargo module is at least twice as long as the towing bicycle and / or the trailer cargo module is at least twice as long as the towing bicycle and / or the cargo receiving area of the front cargo module is at least the length of the towing bicycle, particularly preferably at least twice as long as the towing bicycle. The towing bicycle thus preferably has a very short construction, preferably a length of at most 1.3 meters or at most 1 meter from the front axle to the rear axle, so that it can also be used in extremely confined spaces without a front cargo module and without a trailer cargo module.

[0029] FIG. 1 shows a schematic diagram of a first embodiment of a towing bicycle 1 of a modular cargo vehicle according to the invention, wherein in particular the rear axle of the towing bicycle 1 and thus the rear wheel 3 or the two rear wheels 3 are in a single towing bicycle operating mode ( Figure 1a ) and single traction bicycle scooter operation mode ( Figure 1b ) is driven. Therefore, the same traction bicycle 1 is used as Figure 1a The traction bicycle operation in the embodiment of the present invention is characterized in that the rider sits on the rider seat 4 and pedals the pedal crank 5, and as Figure 1b The scooter operation in particular is that the rider stands on the standing surface 13 and pushes off the road with one foot. Preferably, the rear axle has two wheels 3, so that the tractor 1 is a three-wheeler. The trailer 1 comprises a front axle with a front wheel 2, and comprises a rear axle with one or, as mentioned above, two rear wheels 3.
[0030] like Figure 2a and 2b As shown, the pedal crank 5 of the traction bicycle 1 can be designed to drive the front axle of the traction bicycle 1 instead of the rear axle of the traction bicycle 1 ( Figure 1a and 1b ). For this purpose, the pedal crank 5 can preferably be arranged directly on the front axle.
[0031] In addition to being driven manually by the rider via the pedal cranks 5, the traction bicycle 1 may have a drive battery 12 and a drive motor (see Fig. 9 ).
[0032] For example, the traction bike can be used to quickly transport relatively small amounts of goods on short and / or narrow routes. The traction bike 1 can be an autonomous vehicle (tractor), for example for transporting small goods. The traction bike 1 can also be used to transport people.
[0033] FIG. 3 shows a traction bicycle 1 and a front cargo module 6 of a modular cargo vehicle according to the present invention in a traction bicycle front cargo module operation mode (3a) and a traction bicycle front cargo module scooter operation mode (3b). Figure 3b ) in the schematic diagram.

[0041] The cargo vehicle comprises a trailer cargo module 9, wherein the trailer cargo module 9 and the towing bicycle 1 are designed such that the front end of the trailer cargo module 9 can be coupled to the rear end of the towing bicycle 1. The trailer cargo module 9 comprises a preferably axially approximately central axle with two wheels 10 and a cargo receiving area 11. The cargo receiving area 11 may have side walls and essentially form a container which is open or closable at the top.
[0042] The trailer cargo module 9 can have a drive battery 12 (preferably a plurality of drive batteries 12 ) and an electric drive motor, and an axle of the trailer cargo module 9 can be driven by means of the electric drive motor.
[0043] In this operating mode, relatively large amounts of cargo can be transported - using the trailer cargo module 9. The vehicle simultaneously remains highly maneuverable.
[0044] In accordance with Figure 6a and 6b In the embodiment of the present invention, the front axle of the traction bicycle 1 is not directly driven either. Figure 5a and Figure 5b ) in a seated position (i.e., in bicycle mode) and in the following figure ( Figure 5b and Figure 6b ) and using the same traction bike again in a standing position (i.e., in scooter mode).
[0045] like Figure 6a and 6b As shown, one or more rear wheels 3 of the rear axle of the trailer 1 can be designed so that they are not in contact with the ground when the trailer cargo module 9 is coupled to the trailer, and the front axle of the trailer 1 can be driven by a pedal crank 5.
[0046] FIG. 7 shows the front cargo module and trailer cargo module in the towing bicycle operation mode ( Figure 7a ) and scooter operation mode with towing bicycle front cargo module and trailer cargo module ( Figure 7b ) is a schematic diagram of the entire modular cargo vehicle.
[0047] Therefore, the cargo vehicle includes the towing bicycle 1 , the front cargo module 6 and the trailer cargo module 9 .
[0048] In this state of the cargo vehicle a relatively large amount of cargo can be transported.
[0049] The drive battery 12 can be placed at the front of the bicycle, especially at the center, so that the various components are independent (see Fig. 9 ). With this complete configuration, the small wheels of the trailer 1 preferably do not come into contact with the ground.
[0050] FIG. 8 again shows the same complete vehicle as in FIG. 7 , only the front axle of the towing bicycle 1 is driven instead of the rear axle.
[0051] The front cargo module 6 may be at least twice as long as the towing cycle 1. The trailer cargo module 9 may be at least twice as long as the towing cycle 1. The cargo receiving area 8 of the front cargo module 6 may be longer than the towing cycle 1, preferably approximately twice as long.
[0052] Therefore, this modular cargo vehicle can be operated in the modes shown in Figures 1 to 8: single-towing bicycle mode, single-towing bicycle scooter mode, towing bicycle front cargo module mode, towing bicycle front cargo module scooter mode, towing bicycle trailer cargo module mode, towing bicycle trailer cargo module scooter mode, towing bicycle front cargo module and trailer cargo module mode and / or towing bicycle front cargo module and trailer cargo module scooter mode.
[0053] Fig. 9A schematic diagram of possible positions of the drive battery 12 in the towing bicycle front cargo module and trailer cargo module modes in a first embodiment of a modular cargo vehicle according to the invention is shown. For example, the drive battery 12 can be arranged in the front cargo module 6, in particular in the area of the front end of the front cargo module 6. A further drive battery 12 can be arranged in the towing bicycle 1, in particular in the area of the front end of the towing bicycle 1. One or more drive batteries 12 can be installed in the trailer cargo module 9, for example on the cargo receiving area 11, in front of and / or behind the axial center axis.
[0054] Therefore, a cargo bike can have three main components:
[0055] - Single-aisle front carrier (front cargo module 6). For high-load options, the front wheels can be equipped with wheel hub motors and batteries can be integrated.
[0056] - A traction machine (traction bicycle 1 ), preferably in the form of a tricycle with a V-shaped or A-shaped arrangement - One axle is electrically driven and the tricycle can be equipped with a small battery in order to operate in stand-alone mode.
[0057] - Trailer (Trailer Cargo Module 9): with or without drive hub motors and batteries.
