Description

Technical Field

[0001] This invention relates to a transport and loading assembly for a motor vehicle, which, according to a general concept, is a passenger vehicle, particularly a passenger car, including a loading area extending to a rear opening (such as a tailgate, rear door, or trunk lid). It also relates to a transport cart, loading equipment for the loading assembly, and a loading method using the transport and loading assembly. For example, the passenger car may be designed as a station wagon, high-roof station wagon, SUV, pickup truck, van, minivan, hatchback, or sedan. In this case, the transport and loading assembly has a transport cart comprising a chassis with multiple rolling devices and at least one fixed, removable, or replaceable transport container. The transport container may be formed, for example, a basket, container, refrigerated box, child seat receiving area, tool receiving area or the body of a tool cart, workshop cart, craftsman's cart, and / or leisure equipment receiving area. The chassis or transport vehicle as a whole is adjustable between a transport position and a loading position. In the transport position, the transport vehicle can be placed on a base and moved to transport the received object. In the loading position, the chassis and / or transport vehicle as a whole has minimized external dimensions for easier loading and storage in the loading area. Furthermore, the transport and loading assembly has a loading device configured to accommodate or secure the transport vehicle in the loading area of ​​the motor vehicle, and includes a loading mechanism. The loading mechanism is used to at least partially automatically load the transport vehicle into and / or unload the transport vehicle from the loading area. In this case, the transport vehicle has a height adjustment device by which the height of the transport vehicle or the vertical distance of the transport container relative to the rolling device can be set, particularly steplessly or at least in multiple stages, so that a predetermined docking position and / or support position different from the transport and loading positions can be set relative to the loading device, from which at least partially automatic loading operations can be performed by the loading device. "Multi-stage" means that the height of the transport container can be adjusted between a maximum and minimum height setting in at least five, preferably ten, intermediate stages. For this purpose, the height adjustment device can have a height-adjustable mechanism, for example, on the chassis and / or transport container. Vertical adjustment can be achieved through, for example, linearly movable, pivotable, helical rotatable, telescopic, scissor-type, or knee-type devices and / or all other known and suitable devices for manual, partially automatic, or fully automatic height adjustment, driven, for example, manually, mechanically, hydraulically, and / or electrically. This means that, apart from the transport position and loading position, the height of the transport vehicle or its transport container can be precisely adapted to the loading equipment located in the rear opening or loading area. The possibility of dividing the loading position and support position ensures that the loading equipment can safely pick up the transport vehicle and automatically load it into the loading area without any problems. Background Technology

[0002] DE10043398A1 discloses a system for loading a transport vehicle, wherein a forklift can be connected to a receiving device in the loading area of ​​the transport vehicle via a coupling device. The forklift has a transport container and a rigid chassis, the distance between which is adjustable. For loading, the transport container is adjusted to a suitable height and moved to the parking area of ​​the transport vehicle. The chassis is then raised to a position above the loading area so that the forklift can be fully moved into the loading area. In an alternative embodiment, a telescopic lift truck is used, which is pushed onto the loading area by the rollers of the transport container itself, while the chassis is partially folded and partially moved to a position above the loading area via a telescopic device.

[0003] DE102016114310A1 discloses a loading vehicle having a receiving area adjustablely supported on a chassis. The height of the receiving area can be adjusted relative to the chassis, allowing it to be pushed onto the loading area. Once the receiving area is positioned on the loading area, the chassis can be folded around the receiving area into a folded position.

[0004] US2006 / 0061116A1 discloses an extendable equipment platform for a pickup truck. The platform can be moved away from the loading area via extendable loading rails, then placed on a base surface and moved thereby via deployable and height-adjustable legs.

[0005] DE102019212501A1 discloses a commercial vehicle with a load-bearing floor, in which a transport vehicle is integrated, the transport vehicle and the load-bearing floor forming a common loading area. The transport vehicle has a height-adjustable folding chassis.

[0006] DE19521549A1 describes a holding device having two rails disposed on a loading area, on which a receiving area frame can be loaded. The frame is equipped with folding legs that unfold during unloading and fold up during loading.

[0007] US2014 / 0356112A1 discloses a pickup truck with loading rails that hold a transport vehicle and push it out of the loading area. The chassis can then extend over the transport vehicle held by the loading rails, and the chassis can be height-adjusted via scissor joints. With the height-adjustable chassis, the transport vehicle can be moved on a base surface and, once the appropriate height is set, can be received again from the loading rails.

[0008] US2019 / 0235508A1 describes an autonomous transport vehicle on which a movable receiving container having retractable outriggers for this purpose can be loaded and unloaded.

[0009] DE102014016905A1 discloses a receiving frame that can be mounted on the track system of an ambulance and has a foldable chassis.

[0010] US2002 / 0149176A1 shows a foldable transport vehicle with four wheels attached to telescopic devices. The wheels are thus height-adjustable in pairs for loading operations.

[0011] DE102015220655A1 discloses a transport and loading system designed to make loading goods easier and more convenient, especially during shopping. Furthermore, its purpose is to avoid the need to transfer goods from the shopping cart to the trunk, which is common practice. For this purpose, the transport vehicle has a foldable and unfoldable frame. Additionally, a conveyor belt, pallets, and / or frames are provided that can be moved from under the transport container to automatically pick up the container and load it into the trunk.

[0012] One drawback of known transport and loading systems is that the alignment of the transport vehicle with respect to the loading equipment can vary significantly, especially on uneven surfaces. This can prevent the vehicle from being picked up without problems on conveyors, flatbeds, or frames. This means that in many cases, the vehicle needs to be manually aligned and held in order to move the loading equipment underneath. However, this manual alignment is often impossible or requires considerable effort, especially with fully loaded vehicles. Furthermore, the vehicles in known transport and loading systems are relatively cumbersome to operate, particularly when used on stairs or elevators, where they are essentially unsuitable.

[0013] The purpose of this invention is to avoid the aforementioned disadvantages of general transport and loading components, and to achieve simple and convenient unloading and loading of transport vehicles in the loading area, as well as convenient handling. Summary of the Invention

[0014] This objective is achieved through a transportation system. In this system, to adjust the height of the transport vehicle or the vertical distance to at least three rolling devices, the chassis has at least a partially retractable linkage with at least three telescopic devices that can be adjusted independently of each other, either fully automatically or partially automatically. One of the rolling devices is held on each telescopic device. In this way, the height of the transport vehicle or transport container can be adjusted, particularly steplessly, while simultaneously keeping the chassis stably fixed at the height set in each case. For better loading, in addition to height adjustment relative to the loading equipment or the loading area of ​​the associated motor vehicle, the height of the transport vehicle can also be adjusted to the height of the corresponding user in the transport position. This makes it convenient to operate the transport vehicle when transporting objects, regardless of the user's height. In addition to the pure height adjustment of the transport vehicle, the at least partially retractable linkage with at least three telescopic devices that can be adjusted independently of each other can also adjust the alignment of the transport container with the motor vehicle and its loading area. This horizontal alignment can be made relative to two mutually perpendicular horizontal spatial axes, for example, in the longitudinal and transverse directions of the transport vehicle.

[0015] Of particular advantage is that each rolling device for adjusting the vertical distance relative to the transport container is fixed to its own telescopic device, thereby allowing the transport vehicle or transport container to be aligned with two horizontal spatial axes relative to the loading area or its loading edge, so as to enable unobstructed grabbing and loading of the transport vehicle by the loading equipment.

[0016] In a particularly preferred embodiment, a sensor device operates between the loading equipment and the transport vehicle, and based on its signal, the height of the transport vehicle relative to the loading equipment can be automatically adjusted in a predetermined manner. In this way, the optimal height of the transport vehicle relative to the loading equipment can be set substantially automatically for picking and loading.

[0017] Advantageously, the height adjustment device can be used to set different vertical distances between the transport container and at least two spaced-apart rolling devices or wheels. This allows for not only simple height adjustment of the transport vehicle, but also horizontal alignment of the transport container relative to the loading equipment, or adaptation of the transport container's position to the alignment of the loading equipment. This means, for example, that even if the motor vehicle and / or transport vehicle are aligned at an angle due to uneven surfaces, the transport vehicle can still remain stably held on the loading equipment.

[0018] It is also advantageous if the loading equipment is equipped with a guiding aid for the transport vehicle, which operates in the vertical direction and allows the transport vehicle to be positioned relative to the guide aid. The guiding aid serves as a stop for the reliable positioning of the transport vehicle relative to the loading equipment or to the motor vehicle. Furthermore, it provides precise vertical guidance during height adjustments of the transport vehicle or during alignment of the transport container with the loading equipment.

[0019] In this configuration, the guiding aid is advantageously pivotally held on the loading equipment so that it can rotate horizontally and stop in an enclosing manner at the corner area of ​​the transport container formed by its two sides. This rotating guiding aid that encloses the corner area at an angle ensures particularly precise vertical guidance. Especially when two such guiding aids that can rotate toward each other are arranged in pairs, a certain degree of alignment relative to the loading equipment can also be achieved when the transport vehicle is positioned.

[0020] Advantageously, the transport vehicle is equipped with a chassis receiving area. In the loading position, the chassis can be at least partially received within this receiving area. Thus, for example, during loading and transport in the loading area, the chassis can be at least partially contained within the outer contour of the transport vehicle.

[0021] Preferably, the chassis receiving area has at least one telescopic receiving area. In the loading position, at least one telescopic device can be at least partially retracted into this telescopic receiving area. Through this telescopic receiving area for receiving at least one telescopic device, the chassis can be at least partially moved to a particularly space-saving position, such as within the outer contour of the transport vehicle, during loading and transportation within the loading area.

[0022] Furthermore, the loading equipment advantageously includes an engagement device that can be displaced to an extended position outside the loading area to establish or release a positive locking and / or friction locking connection with the transport vehicle. This allows the transport vehicle to be secured relative to the loading equipment at a distance from the associated motor vehicle to initiate loading operations, or to be released to complete unloading operations. In this way, it can be ensured that no damage to the motor vehicle is caused by contact with the transport vehicle throughout the entire loading operation.

[0023] In this connection, if the engagement device is held on at least one extendable loading component of the loading equipment, the transport container can be supported in the direction of gravity in a supported position on the transport vehicle. This allows the transport vehicle to be held at least partially independent of the chassis, such that after the connection between the transport vehicle and the engagement device has been established, the chassis can be moved at least partially to the loading position, or the telescopic linkage can be moved at least partially to the telescopic receiving area. The extendable loading component can be adjusted relative to the rest of the loading equipment by any known and suitable type of drive mechanism, such as electric gear / rack and pinion or belt drive, hydraulic drive, and / or any other linear drive mechanism.

[0024] In addition to the forward locking and / or friction locking connection with the transport vehicle, the engagement device can also be used to secure the transport vehicle in a loading position opposite to the direction of gravity, which is highly advantageous. In this way, the transport vehicle can be secured to the loading equipment in all directions in the loading position, which allows the transport vehicle in the loading position to be transported and received safely and quietly in the loading area.

[0025] Advantageously, the engagement device is formed on the loader, which can be moved by a motor on the extendable loading component. Therefore, a motor-driven loader with this type of engagement device can be used to automatically and safely pull a transport vehicle into the loading area of ​​a motor vehicle during loading, or to push it out of the loading area during unloading. At least one loader can be moved on the loading section or relative to the rest of the loading equipment by any known and suitable type of drive mechanism, such as electric gear / rack and pinion or belt drives, hydraulic and / or other linear drives.

[0026] For example, if the loader has a hollow profile with longitudinal grooves on the top, it is more convenient to engage it via a rear engagement element on the side of the transport vehicle, and vice versa. This makes it particularly easy to establish a positive locking and / or friction locking connection between the loader and the transport vehicle, thereby also securing the transport vehicle firmly in the vertical direction relative to the loading equipment, especially via a rear engagement connection. Alternatively, the engagement device may also have a locking mechanism that can be switched manually, partially, or fully automatically between a released position and a locked position. This locking mechanism allows for a positive locking and / or friction locking connection acting in the vertical and / or horizontal directions between the loader and the transport vehicle.

[0027] Furthermore, it is advantageous that the loading equipment has at least one support area extending along the loading direction, along which movable support devices of the transport vehicle, such as rollers, wheels, sliding bearings, or other movable support devices, can move. This allows the transport vehicle to move along the loading equipment without problems and maintains low noise even under high load weights, facilitating loading or unloading.

[0028] In another particularly preferred embodiment, the transport container has at least two detachable or connectable partial containers. This allows the transport container to be used appropriately depending on the transported components or purchased items to be received.

[0029] In this configuration, the two sub-containers advantageously have two sidewalls that can abut against each other at their end faces. These sidewalls can be secured to each other by connecting devices and countermeans, which can then be separated by horizontal displacement of each other. This makes it particularly easy, and especially allows for automated, connection or separation of the two component retainers.

[0030] Furthermore, it is advantageous that the transport container is detachably secured to the chassis, so that it can be firmly held to the chassis during transport on the one hand, and can be handled or carried independently of the chassis on the other.

[0031] In a particularly preferred embodiment, the chassis has at least two partial chassis that can be detachably connected to each other via locking devices. This allows the transport vehicle to be sized to suit needs or applications.

[0032] It is advantageous if at least one sub-chassis is equipped with a folding or fixed support chassis. This allows the chassis to be stable or movable in an upright position, even when using only the sub-chassis that is separate from the rest of the chassis.

[0033] Furthermore, advantageously, the loading device also has two loading components that can extend independently of each other, wherein each sub-container can be supported on each loading component in the direction of gravity, and each loading component has an engagement device for establishing or releasing a positive locking and / or friction locking connection with the sub-container. In this way, the sub-supports or sub-chassis can be moved independently of each other by the loading device. This allows them to be loaded and unloaded independently of each other, or connected and separated from each other by the relative movement of the connecting devices and connecting opposite parts.

[0034] Preferably, the height adjustment device is electrically operated and has at least one battery device. This allows the height of the transport vehicle to be easily adjusted to the height or alignment of the loaded equipment, or to the height of the user.

[0035] Advantageously, the transport vehicle includes an electrical connection device for connecting to the battery equipment. Furthermore, a connecting connector is provided on the loading equipment, which can be connected to the power source of the motor vehicle. At a fixed position on the transport vehicle on the loading equipment, the electrical connection device can contact the connecting connector. In this way, the battery equipment of the transport vehicle can be charged by the power source of the motor vehicle at its fixed position in the loading area.

[0036] Alternatively or additionally, a second electrical connection device may be provided on the transport vehicle, which can be connected to a connecting counterpart on the vehicle side and can supply power to the cooling unit on the transport vehicle. In this way, a cooling container can be provided inside the transport container, which can be cooled at a fixed location on the transport vehicle via the cooling unit and power supply of the motor vehicle. Alternatively, in addition to the refrigerated container, electric food preparation or heating equipment, such as a microwave oven, electric stove, or oven, may also be provided.

[0037] If the transport vehicle has a traction drive, automatic movement via that drive is also convenient. This means that heavier loads picked up at the transport container can be easily transported by the transport vehicle.

[0038] In addition, the transport vehicle can advantageously have a traction assistance system to achieve automatic control, thereby enabling the transport vehicle to move autonomously.

[0039] Furthermore, it is convenient if the transport vehicle has lighting equipment, such as spotlights or illuminated markers. In this way, the battery equipment mounted on the transport vehicle can be used for other functions.

[0040] It is also advantageous if the transport container or the sub-containers that make up the transport container are designed to be collapsible. This allows the transport container to be moved in a particularly compact manner within the loading area, whether it is empty or in a loading or stationary position.

[0041] In another advantageous embodiment, the transport vehicle is equipped with goods registration and / or payment devices, which may include, for example, a display, scanner, payment application, or card reader. This allows the transport vehicle to conveniently record the goods placed in the transport container and / or a particularly simple payment process. In this way, for example, payment can be made for goods placed in the transport container during the shopping process without having to remove the goods from the transport vehicle again for the payment procedure.

[0042] In addition, providing integrated rain covers on transport vehicles can conveniently cover the transport containers and the transported goods received within them.

[0043] Furthermore, the aforementioned objective is achieved solely by the transport vehicle 10 of the transport and loading assembly 2 in one of the above embodiments. Additionally, the aforementioned objective is achieved by the loading equipment itself of the transport and loading assembly 2 in one of the above embodiments.

[0044] Furthermore, the aforementioned objective is achieved through a loading method using a transport and loading assembly according to one of the above embodiments. In a first step, a transport vehicle approaches a loading device installed in a motor vehicle. In a second step, the position of the transport vehicle is determined, particularly its height and / or alignment relative to the loading device. In a third step, based on the determined position, a parking position of the transport vehicle is automatically set, in which the transport container is arranged relative to the loading device in a predetermined manner, for example, particularly relative to its height and / or alignment. This allows the transport vehicle to be aligned relative to the motor vehicle, even in cases where the height and / or alignment relative to the motor vehicle is inconsistent, for example, due to uneven or inconsistent base surfaces. In this way, loading operations, particularly partially or fully automated loading operations, can be initiated by the loading device.

[0045] Advantageously, in the third step, the distances of at least two, at least three, or four or all of the rolling devices can be adjusted individually relative to the transport container to precisely match the height and alignment of the transport container relative to the motor vehicle or the loading equipment housed therein.

[0046] Furthermore, in the fourth step, it is convenient to move the transport vehicle from the docking position to the supporting position, where the transport vehicle is supported on the loading equipment along the direction of gravity GR. In this way, for example, the weight of the transport vehicle or the transport container filled with transported goods can be partially borne by the loading equipment and the motor vehicle, thus partially reducing the weight of the transport chassis and preparing for loading.

[0047] In the supported position, a positive locking and / or friction locking connection is established between the transport vehicle and the transfer equipment, so that in the fifth step, the chassis portion facing the motor vehicle is moved to the chassis receiving area. In this way, the positive locking and / or friction locking connection required for the automatic loading operation is also generated when the transport vehicle is placed on the loading equipment, thereby allowing the transport vehicle to be moved into or out of the loading area.

[0048] Furthermore, advantageously, in the sixth step, the transport vehicle can be moved by the loading equipment so that a portion of the chassis is accommodated in the chassis receiving area and supported on the base surface facing away from the motor vehicle. Therefore, during the loading operation, as long as the transport vehicle is not yet stably installed, or once the transport vehicle is no longer stably installed on the loading equipment, the weight of the transport vehicle is still partially transferred to or removed from the loading area via the chassis.

[0049] Advantageously, in the sixth step, the chassis portion supported on the base surface is adjusted to compensate for vertical displacement, such as the descent of the motor vehicle due to weight transfer from the transport vehicle, or vertical displacement of the rolling device due to unevenness of the base surface. Vertical displacement can be determined, for example, by a pressure or tilt sensor system, thereby adjusting or controlling the distance between the rolling device and the transport container based on signals from the sensor system to maintain the transport container's set alignment relative to the loading equipment.

[0050] In this way, the transport vehicle can be loaded without any problems, even with large receiving weights and uneven base surfaces.

[0051] If, in the seventh step following the sixth step, the transport vehicle is moved to the loading position, it is more convenient that once the transport vehicle has been moved to the loading area and stably placed on the loading equipment, the chassis portion, which is away from the motor vehicle, is also moved to the chassis receiving area. At the loading position, the transport vehicle can therefore be moved to a particularly compact location within the loading area.

[0052] Furthermore, in the unloading operation following steps one through seven, the transport vehicle moves out of the loading area again and comes against the loading equipment V. Thus, in reverse order, the portion of the chassis away from the motor vehicle is extended first, and then the portion of the chassis facing the motor vehicle is extended, so that the weight of the transport vehicle can be gradually removed again from the chassis on the base surface.

[0053] Here, it is particularly advantageous if the chassis extends and enters the docking position in response to signals from pressure or position sensors, so that the chassis can safely and partially or fully automatically enter the docking position during unloading.

[0054] It should be noted that all the above-described features of the object according to the invention are interchangeable or combined with each other, provided that such interchangeability or combination is not excluded for technical reasons. Attached Figure Description

Detailed Implementation

[0056] Figure 1 and Figure 2 The transport and loading assembly 2 for a motor vehicle 4 is shown. An exemplary form of the motor vehicle 4 is a passenger vehicle with an SUV design, whose loading area 8 can be accessed through a rear opening 6.

[0057] In this configuration, the transport and loading assembly 2 comprises a transport vehicle 10 with a transport container 12, which is held removably on a chassis 14 having, for example, four rolling devices 16. The rolling devices 16 can be designed as a single roller, or alternatively, as pairs or multiple rollers. In any case, the rolling devices 16 can be adjusted via the chassis 14 between the transport and loading positions shown. In the transport position, the transport vehicle 10 can be parked and moved on the base surface G via the rolling devices 16. In the loading position, the chassis 14 rests on the transport container 12, or is at least partially displaced into a chassis receiving area 18 disposed on the transport container 12. This provides the transport vehicle 10 with reduced external dimensions for loading operations.

[0058] Both the transport container 12 and the chassis 14 can be made of any known material suitable for manufacturing the transport vehicle 10. In particular, they can be made at least in part of metal, plastic, glass, or carbon fiber materials, or combinations thereof.

[0059] Furthermore, the transport and loading assembly 2 has a loading device 20 located on the loading base plate 22 of the loading area 8. This forms a loading mechanism 24 that allows the transport vehicle 10 to be loaded into or unloaded from the loading area 8 of the motor vehicle 4. For this purpose, the loading device 20 has a loading member 26, such as a plate, carrier, telescopic arm, or rail, which can extend beyond the loading area 8. The loading member 26 is displaceably held on a support plate 28, which can be placed on the loading base plate 22. The support plate 28 can be advantageously designed to be height-adjustable, such that, for example, when not in use, it can be lowered alone or together with the loading device 20 into the depth of the loading area 8. Furthermore, a coupling device 30 is provided on the loading device 20 to provide a positive locking and / or friction locking connection with the transport vehicle 10. For this purpose, the coupling device 30 is used to establish a positive or friction connection with the coupling counterpart 32 of the transport vehicle 10, and for example, as Figure 3 As shown, it is held on the loading component 26 of the loading device 20. Therefore, the engaging device 30 can be moved together with the loading component 26 to an extended position outside the loading area 8. Figure 1 and Figure 2 As shown, the engaging member 32 can be formed by a separate forward-fitting device protruding from the lower side U of the transport vehicle 10. Alternatively, the engaging member 32 can also be formed by an existing or integrated area or component of the transport vehicle 10, capable of forming a forward-locking and / or friction-locking connection with a correspondingly adapted engaging device 30 of the loading device 20. Alternatively or additionally, the engaging device 30 or the engaging member 32 may also have a locking mechanism that can be switched manually, partially automatically, or fully automatically between a release position and a locked position, by which a connection can be created between the loading device 20 and the transport vehicle 10, which operates in the vertical and / or horizontal directions and is a forward-locking and / or friction-locking connection (not shown).

[0060] In order to establish a positive locking and / or friction locking connection between the loading device 20 and the transport vehicle 10 to facilitate problem-free loading operations, such as Figure 1 and Figure 2 As shown, the transport vehicle 10 has a height adjustment device 34 integrated into the transport container 12, or alternatively held on the chassis 14. This can be operated fully automatically, partially automatically, or manually, and in the transport position on the chassis 14, the height H of the transport vehicle 10 relative to the corresponding base surface G can be adjusted, or the lower side U of the transport container 12 can be aligned with the loading device 20. Here, the vertical distance A between the transport container 12 and the single rolling device 16 formed mainly by the chassis 14 is adjusted.

[0061] In this respect, the chassis 14 has at least a partially retractable link 36 that connects the rolling device 16 to the transport container 12. To set the desired distance A, the height adjustment device 34 also has a control device 38 by means of which at least one electric actuator 40 can be partially or fully automatically controlled for adjusting at least one retractable link 36. Preferably, at least two rolling devices 16, particularly at least three, four, or all of the rolling devices 16, are held on separate telescopic devices 37 so that different vertical distances A can be set thereon fully automatically, semi-automatically, or manually. Therefore, in addition to adjusting the height H, the alignment of the transport container 12 relative to the loading component 26 can also be adjusted, which may be necessary, for example, when the motor vehicle 4 and / or the transport vehicle 12 is situated on, for example, an uneven base surface G and is tilted to some extent.

[0062] To enable the vehicle to supply power independently of the height adjustment device 34, the vehicle includes a battery device 42. Furthermore, the height adjustment device 34 preferably includes a sensor device 44, which, together with a sensor device 46 on the loading device 20 or on the rear opening 6 of the vehicle 4, forms a sensor arrangement 48 operating between the transport vehicle 10 and the loading device 20. This is used for automatically detecting mutual height and / or alignment, and for transmitting corresponding information or signals. Based on signals from the sensor arrangement 48, the control device 38 can set the telescopic device 37 to different lengths to set the desired height H of the transport vehicle 10 and the alignment of the transport container 12 relative to the loading device 20 or relative to the loading edge of the loading area 8.

[0063] In order to load the transport vehicle 10, in the first step of the transport position, the transport vehicle 10 is brought close to the loading equipment 20 along the loading direction V, such as... Figure 4 As shown. Using sensor arrangement 48, the position of the transport vehicle 10 relative to the motorized vehicle 4 is determined in the second step. In the third step, the height adjustment device 34 is then used to automatically adjust the height H of the transport vehicle 10 relative to the corresponding base plane G, or to align it with the lower side U of the transport container 12 relative to the loading device 20, so as to bring the transport vehicle into place as shown. Figure 3 The parking position is shown. For this purpose, the vertical distance A between the transport container 12 and the single rolling device 16, mainly formed by the chassis 14, is adjusted.

[0064] In this case, a height adjustment device 34 can be used, for example, to set a first height H1 of the lower side U of the transport vehicle 10 relative to the base plane G, such as... Figure 3 As shown, the two corner areas 50 of the transport container 12 can be respectively parked on the guide auxiliary device 52 of the loading equipment 20. From Figure 4As can be seen, each of the guide aids 52 is formed by an exemplary angular element, which is pivotally held and surrounds the corresponding corner region 50, and can dock on the two side surfaces S forming the corresponding corner region 50. Due to the horizontally pivoting guide aids 52, the transport container 12 is guided according to... Figure 3 The lower side U is centered at a first height H1 between the guide aids 52, and can then be adjusted in a guided manner in the vertical direction. In order to optimally detect the corresponding current height H of the transport vehicle 10 or the current height H1 of its lower side U, the sensor device 46 in the sensor arrangement 48 can also be integrated into, for example, the guide aid 52.

[0065] from Figure 3 It can also be seen that the positioning of the guide auxiliary device 52 and the selection of the first height H1 should ensure that the mating opposite member 32 is exactly above the mating device 30. Figure 4 As shown, the engagement device 30 is formed, for example, by a longitudinal groove 54 that allows for rear-engagement from above, and an inlet extension 56 is formed in the groove. This has a slightly larger size than the corresponding rear-engagement element 58 of the engagement counterpart 32, which is formed, for example, by a screw head 60, such as a flathead, countersunk, or hammerhead.

[0066] In the fourth step, the height adjustment device 34 can be used to move the transport vehicle 10 from... Figure 3 The docking position shown is moved to the support position, where the second height H2 of the lower side U is set to... Figure 5 As shown. In this case, the engagement device 30 is applied to engage the opposing member 32, and the corresponding rear engagement element 58 enters the inlet extension 56 of the longitudinal groove 54. This supports the transport container 12 from the loading member 26 along the gravity direction GR, on which the engagement device 30 is mounted. As a result, in the fifth step, the telescopic device 37 arranged adjacent to the motor vehicle 4, together with the rolling device 16 held thereon, can now be moved into the chassis receiving area 18. Preferably, this has a telescopic receiving area 62 of appropriate size to fully receive the wall link 36.

[0067] In particular, from Figure 4 As can be seen, the coupling device 30 is formed on two loading vehicles 64, and the loading vehicles 64 can be connected from... Figure 2 and Figure 4 The extended position shown is shifted along the loading member 26 to the loading area 8. During this displacement, the corresponding rear engagement element 58 engages behind the associated longitudinal groove 54 and enters a stop position thereon, thereby establishing a positive locking connection between the engagement device 30 and the engagement counterpart 32 along the loading direction V, and in the sixth step, the transport container 12 is loaded by the loading slider 64 from... Figure 5 The vehicle is pulled into loading area 8 at the indicated position. Here, the weight of the transport vehicle 10 is partially supported on the loading device 20 and partially supported on the base surface G by the still-extending telescopic device 37 and associated rolling device 16 of the chassis 14, which is away from the motor vehicle.

[0068] During the further loading operation, the telescopic device 37, which is far from the motor vehicle 4, is also moved into the telescopic receiving area 62 set up for this purpose in the seventh step before contacting the motor vehicle 4, thereby placing the transport vehicle 10 in a position where... Figure 6 The loading position shown is where the weight is fully supported on the loading device 20.

[0069] In this configuration, as a way of fixing the position of the transport container 12 in contact with the loading component 26, the rear engagement connection between the engagement device 30 and the engagement counterpart 32 is also opposite to the direction of gravity GR. This allows the remaining telescopic devices 37 to be moved into the chassis receiving area 18 or the telescopic receiving area 62 provided for them as the loading vehicle 64 shifts. Thereafter, the chassis 14 and the transport vehicle 10 are in the loading position as a whole, as... Figure 6 As shown. Upon reaching the terminal position, the loading vehicle 64 and / or the transport vehicle 10 are additionally secured relative to the loading device 20 or relative to the motor vehicle 4, and are thus in a fixed position to ensure that the transport of the transport vehicle 10 and the motor vehicle 4 is safe and positionally stable.

[0070] To ensure smooth loading operations in the loading area 8 even when the transport vehicle 10 carries a high transport weight, in addition to the engaging pair 32, an additional movable support device 66 can be provided on the lower side U of the transport container 12. See details [link to relevant documentation]. Figure 2 and Figure 7 These movable support devices 66 may be in the form of rollers, rolling pins, or sliding bearings, and they can be moved along corresponding, for example, track-shaped support areas 68 that extend on the loading device 20 in the loading direction V, particularly from... Figure 4 This can be seen from the text.

[0071] from Figure 6 It can also be seen that an electrical connection device 70 can be installed on the transport vehicle 10, which is connected to the battery device 42 and contacts the connecting component 72 at a fixed position in the loading area 8. The connecting component 72 communicates with the power unit 74 of the motor vehicle 4, such as the vehicle battery and / or alternator of the motor vehicle 4. In this way, the battery device 42 of the transport vehicle 10 can be periodically recharged at a fixed position in the loading area 8.

[0072] Furthermore, a second electrical connection device 76 may be provided on the transport vehicle 10, which may also contact the connecting counterpart 72 of the motor vehicle 4 in a fixed position and connect to the cooling unit 78 provided on the transport container 12. Thus, whenever the transport vehicle 10 is in a fixed position within the loading area 8, the cooling unit 78 can cool the cooling box 80, which is removably received on or integrated into the transport container 12. Alternatively, or in addition to the cooling box 80, equipment for preparing food, such as a microwave oven or electric oven (not shown), may also be provided via the battery device 42 and / or via the connection device 76.

[0073] The periodic recharge capability of the battery device 42 means that it can also be used to provide power to other functional units. For example, according to Figure 1 and Figure 2 The transport vehicle 10 may have a traction drive 82 for at least partially automating the movement of the rolling device 16. In this case, the traction drive 82 may be controlled by the user and / or by a traction assist system integrated, for example, in the control unit 38. Furthermore, the transport vehicle 10 may include lighting equipment 84, for example, formed by spotlights and / or illuminated advertising.

[0074] Furthermore, for example, a cargo registration and / or payment device 88 can be installed on the handle 86 of the transport vehicle 10. This device 88 can register the cargo stored in the transport container 12, for example, via a scanner 92, and display the information on a display 90. The display 90 can also be used to operate a payment application stored on a control device 38 or another computer device, by means of which the detected goods can be paid for directly, for example, by means of a stored bank account and / or by means of a card reader 94. Thus, the goods no longer need to be removed from the transport container 12 during the payment process. The cargo registration and / or payment device 88 can be removably attached to the transport vehicle 10 or permanently installed thereon, for example, on the handle 86.

[0075] As a further feature, a rain cover 96 may be provided on the transport vehicle 10 to cover the transport container 12. For example, the rain cover 96 may be extended and integrated into the transport vehicle 10, such as on the handle 86. In addition, the handle 86 may be designed to be height-adjustable relative to the rest of the transport vehicle 10.

[0076] Figure 8An alternative embodiment of the transport and loading assembly 2 is shown, wherein the transport vehicle 10 is in the loading position, and the transport container 12 consists of two separable or connectable sub-containers 102 and 104. In addition to this two-part design, the transport container 12 can also be alternatively designed as three or more parts (not shown). In each case, sub-containers 102 and 104 have two sidewalls 106 and 108 that abut against each other, and connecting devices 110 and connecting opposite members 112 are provided on these two sidewalls. In this case, the connecting devices 110 and connecting opposite members 112 are shaped such that they can be pushed into each other by relative horizontal displacement relative to each other to create a forward connection. Furthermore, the existing forward connection can also be released sequentially by the relative horizontal displacement of the connecting devices 110 and connecting opposite members 112 relative to each other, so that the two sub-containers 102 and 104 can be used separately, for example, for transporting or purchasing smaller goods.

[0077] from Figure 8 It can also be seen that the chassis 14 is divided into two separable sub-chassis 114 and sub-chassis 116, which can be connected to each other by a locking device 118. Sub-containers 102 and 104 are respectively fixed to these two sub-chassis. In this respect, the cargo registration and / or payment device 88 can be, for example, removable, and thus can be selectively used on one of the two sub-containers 102 and 104, or can be permanently installed on the two sub-containers 102 and 104, for example, on the handle 86.

[0078] In any case, by varying the displacements of the two loading components 26A and 26B, it is possible to separate the components as follows: Figure 9 The illustrated partial cart 120 consists of only one partial container 102 and two corresponding chassis from two partial chassis 114. To ensure that the partial cart 120 can also stand stably relative to the base surface G, a support chassis 122 is also provided on the corresponding partial cart 114. This support chassis 122 holds the partial cart 114 so that it can be unfolded, for example, and through this support chassis 122, the partial cart 120 can be lowered or moved on the base surface G by at least one additional rolling device 124. As an alternative to the folding embodiment of the illustrated support chassis 122, this can also be designed as a detachable additional chassis 122A with an additional rolling device 124A, such as... Figure 9 As shown by the dashed lines, the additional chassis 122 A can be connected to the associated sub-containers 102, sub-containers 104 and / or sub-chassis 114, sub-chassis 116, for example, via a horizontal insertion connecting device 110 or connecting counterpart 112 and / or via a locking device 118.

[0079] To separate and connect the two sub-containers 102 and 104 and the sub-vehicles 114 and 116, two independently movable loading components 26A and 26B are provided on the loading device 20. Each loading component interacts with one of the two sub-vehicles 120. For this purpose, two engaging devices 30, a loading vehicle 64, and guiding aids 52 and 52A are provided, as detailed below. Figure 10 As shown. Appropriately, as... Figure 9 As shown, each sub-container 102 and sub-container 104 of the sub-cart 120 is also provided with two engaging counterparts 32 and a movable support device 66. Compared with the two angled external guide aids, the two centrally arranged guide aids 52A only serve as stops in the loading direction V, thereby allowing the connecting device 110 and the engaging counterparts 112 or locking device 118 to be connected or disconnected. In this way, only one of the two loading components 26A and loading component 26B of the loading device 20 can be used to load and unload only one of the sub-carts 120 in a stable and problem-free manner.

[0080] Regardless of whether the transport and loading component 2 is used for the overall transport vehicle 10 or the sub-vehicle 120, the transport container 12 or sub-containers 102 and 104 can be detachably connected to the corresponding chassis 14 or sub-chassis 114 and 116 as needed for use as a basket or other portable container. In another embodiment, sub-containers 102 and 104 can be fixed to sub-chassis 114 and 116 at a position relatively close to the base surface, so that the sub-vehicle 120 can be moved as a transport vehicle or a wheeled luggage box (not shown). Furthermore, the transport container 12 or sub-containers 102 and 104 can be provided with foldable side surfaces S or side walls 106 and 108, respectively, so that the transport vehicle 10 or the sub-vehicle 120 can be loaded more compactly.

[0081] Figure 11 Another alternative embodiment of the transport and loading assembly 2 is shown, wherein the engagement device 30 consists of an extendable clamping arm that interacts with the engagement counterpart 32 on the transport vehicle 10 in the form of a toothed track. The engagement device 30 is extendedly mounted on two equally extendable track-shaped loading components 26, and a vertical guide auxiliary device 52 is also pivotally held at the end of the loading component 26.

[0082] In this embodiment, the transport vehicle 10 rests on two guide aids 52, which are held in an extended position at the start of the loading operation, or, as described above, in a central position between the two guide aids. The desired height H of the transport vehicle 10 is set according to a sensor arrangement 48, which, for example, has sensor devices 46 in the guide aids 52. This height H is defined in such a way that the engagement device 30 formed by the clamping arms can move away from the loading member 26 to engage with the toothed track of the engagement counterpart 32, as shown, thereby establishing a positive locking and / or friction locking connection.

[0083] In this position, the transport container 12 is supported on the loading device 20 in the gravity direction GR, so the telescopic device 37 arranged adjacent to the motor vehicle 4 can be moved into the telescopic receiving area 62, as shown. This allows the clamping arms of the engagement device 30 to be displaced in the direction of the loading area 8, such that the toothed track of the engagement member 32 can now be clamped by the motor-driven gears 130 arranged in the loading direction v on the loading member 26. By driving these gears 130, the transport vehicle 10 is thus loaded into the loading area 8, thereby moving the telescopic device 37, which is away from the motor vehicle 4, into the telescopic receiving area 62 provided for this purpose before contacting the motor vehicle 4.

[0084] In addition, this embodiment may also include the aforementioned connecting device 70 and second connecting device 76, as well as a traction drive device 82 and a cargo registration and / or payment device 88.

[0085] In addition, this embodiment may also provide a fixing device, by which the transport vehicle 10 can be fixed in a fixed position relative to the loading equipment 20 or relative to the loading area 8, so as to ensure unobstructed and stable transportation in the motor vehicle 4.

[0086] Regardless of the embodiment, during the unloading operation, the transport vehicle 10 or sub-vehicle 120 received in the loading area 8 can be unloaded from the motor vehicle 4 again by extending at least one loading member 26, loading member 26A, or loading member 26B to the extended position and continuously extending the telescopic device 37 from the corresponding telescopic receiving area 62, either partially or fully automatically. For this purpose, for example, a sensor system, such as a pressure or tilt sensor system, can be provided to detect the contact between the rolling device 16 and the base surface G, thereby securing the associated telescopic device G at a suitable height H on the transport vehicle (not shown).

[0087] Furthermore, disregarding the embodiments, as an alternative to the transverse orientation to the loading direction V shown in the figures, the transport vehicle 10 or the sub-vehicle 120 may also be aligned parallel to the loading direction V during loading operations, depending on the size of the loading area. For example, in the case of a large motor vehicle 4, two integral transport vehicles 10 may also be loaded in this manner by the loading device 20, wherein the two loading components 26A and 26B are independent of each other and, for example, adjacent to each other parallel to the loading direction V, and held in a fixed position (not shown).

[0088] An operating device 140 is also provided for user activation or direct control of the loading device 20 and / or the transport vehicle 10. For example... Figure 1 As shown, this can be positioned on the transport vehicle 10 or loading device 20 in a fixed or removable manner. Alternatively, the operating device 140 can be integrated into the car key 142 and / or programmed onto a portable computing device 144 (e.g., a smartphone). In either case, the user can control the loading mechanism 24 via the operating device. Thus, the user can move the loading component 26 or one of the loading components 26A and 26B between an extended position and a fixed position. Furthermore, if needed, the user can raise and lower the support plate 28 between an operating position for loading operations and a lowered position for saving space at the loading base plate 22. Additionally, with the aid of the operating device 140, the height adjustment device 34 can also be directly controlled by the user to adjust the height H of the transport vehicle 10 or the distance A between the transport container 12 and the rolling device 16, if necessary.

[0089] It should be noted that all the above-described elements and features of the various embodiments of the object according to the present invention can be interchanged or combined with each other, provided that such interchangeability or combination is not excluded for technical reasons.
