Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, the use of directional terms such as "upper" and "lower" generally means defined based on the drawing plane direction of the drawings, unless otherwise specified. Specifically, "up and down" may be the same in the up and down direction of the building 1000, that is, the height direction of the building 1000, that is, the Z direction, as shown in fig. 1, and the X direction, the Y direction, and the Z direction are the directions of three coordinate axes of three-dimensional coordinates, and "inside and outside" refers to the inside and outside of the relevant parts. In addition, the terms "first", "second", and the like used in the embodiments of the present disclosure are for distinguishing one element from another, and have no order or importance.

As shown in fig. 1-11, the present disclosure provides a cargo transfer system. The cargo transfer system includes a transporting carriage 100, a rail 200 on which the transporting carriage 100 travels, and a cargo-receiving station 300 for temporarily placing cargo. As shown in fig. 2 and 3, the transporting carriage 100 includes a carriage body 10 and a rack 20, and the rack 20 has a transfer mechanism for transferring the goods from one of the transporting carriage 100 and the goods-transceiving stage 300 to the other.

As shown in fig. 10, the transfer mechanism includes a telescopic arm 21, the telescopic arm 21 is capable of being extended and contracted in the Y direction and has a loading surface 211 for contacting with a bottom surface of the cargo (for example, the bottom surface 410 of the cargo box 400 of fig. 2), and the transport cart 100 moves in the Z direction on the rail 200 to move the telescopic arm 21 in the Z direction, so as to place the cargo on the cargo receiving and dispatching stage 300 or transfer the cargo from the cargo receiving and dispatching stage 300 to the telescopic arm 21.

Through the above technical solution, when the cargo transfer system is applied to the building 1000, the cargo can be transferred between the transport trolley 100 and the cargo transceiver station 300 by the extension and contraction of the telescopic arm 21 due to the integration of the above transfer mechanism on the transport trolley 100. Compared with the technical scheme that the logistics trolley in the prior art is only used as a transport means and a plurality of horizontal rails and vertical rails which are arranged in a staggered mode are arranged, the transportation mechanism is integrated on the transport trolley 100, the number of the rails 200 is reduced, the structure of a cargo conveying system can be simplified, and the occupied space of the rails 200 in the building 1000 is reduced.

Moreover, in embodiments in which the hoistway 500 is disposed within the building 1000 to route the tracks 200, reducing the number of tracks 200, i.e., the number of hoistways 500, is beneficial in reducing the space occupied by the entire cargo transport system within the building 1000. Moreover, the goods receiving and dispatching station 300 is arranged in the building 1000 to provide a warehouse for the transport trolley 100 when goods are loaded or unloaded, and the internal structure of the building 1000 does not need to be greatly changed, so that the method has the advantages of reducing the encroachment and transformation on the space in the house of a user.

In addition, the telescopic arm 21 can move in the Y direction and the Z direction by moving the transportation trolley 100 and extending and retracting the telescopic arm 21, so that the cargo can be placed on the placing surface 310 from the telescopic arm 21 or the cargo can be transferred to the telescopic arm 21 from the placing surface 310, and the cargo can be easily transferred.

When a transfer of cargo is desired within the building 1000, the cargo may be placed on the cargo bed 300, such as by a manual or other transfer mechanism, and then picked up by the transfer mechanism of the transport vehicle 100 and transported to the destination via the track 200. For example, to a rooftop for unmanned distribution by a drone. Similarly, cargo from the drone may be transported by the transport vehicle 100 to the interior of the building 1000. In this way, two-way, fast, unmanned delivery from the drone to the user's home can be achieved.

As shown in fig. 2 and 3, in an embodiment of the present disclosure, the transfer mechanism further includes a first Z-direction protrusion 22 and a second Z-direction protrusion 23 both disposed (mounted or integrally formed) on the telescopic arm 21, the first Z-direction protrusion 22 is disposed at an end of the telescopic arm 21 close to the cargo receiving and dispatching platform 300, and the second Z-direction protrusion 23 and the first Z-direction protrusion 22 are spaced in the Y-direction. Like this, owing to be provided with first Z to protruding 22 and second Z to protruding 23 in the flexible direction of telescopic boom 21, at telescopic boom 21 flexible in-process, can prevent that the goods from appearing skidding etc. and removing on telescopic boom, play limiting displacement, avoid the goods to break away from telescopic boom 21 because of moving along Y. Moreover, since the first Z-direction protrusion 22 and the second Z-direction protrusion 23 are spaced apart from each other, when the size of the cargo is matched with the distance between the first Z-direction protrusion 22 and the second Z-direction protrusion 23, as shown in fig. 2, when the telescopic arm 21 is extended, the second Z-direction protrusion 23 can apply a pushing force to the cargo (such as the cargo box 400), so that the cargo is synchronously moved toward the cargo receiving and dispatching table 300, which is advantageous for transporting the cargo to a precise position. Similarly, when the telescopic arm 21 is retracted, the first Z-projection 22 can apply a pushing force to the cargo (the cargo box 400) so that the cargo can be moved to a precise position on the transport vehicle 100 while following the telescopic arm 21.

In the correlation technique, still be provided with the branch goods shift fork on the flexible arm 21, the branch is allocated the fork and can be followed flexible arm 21 and unscrewed and the gyration, and the goods shift fork can be used in on the goods during the time of unscrewing, realizes spacing and being used for the push-and-pull goods so that this goods follows flexible arm 21 motion to the goods, and the goods is released to the goods during the gyration time of gyration shift fork to place the goods with corresponding position. Compare in the scheme that adopts the branch goods shift fork, in the goods conveying system that this disclosure provided, first Z can save the actuating mechanism that is used for driving branch goods shift fork and back-out or back-forth, for example motor etc. when playing spacing to the goods to protruding 22 and second Z, can save and reduce power supply quantity, simplifies mechanical structure, corresponding power supply wiring, reduces the winding risk of appearing laying wire, is favorable to simplifying goods conveying system's structure and reliability.

The "first Z-direction protrusion 22 and the second Z-direction limiting protrusion 23" herein refer to protrusions extending in the Z-direction, that is, protrusions extending in the height direction of the building 1000.

It will be appreciated that the "goods" referred to above may be a variety of specific items such as couriers, takeoffs, etc., or may be a container 400 as shown in fig. 1-9, and the container 400 may be used to hold a variety of items. That is, specific articles may be placed on the telescopic arm 21 for transportation, or specific articles may be placed in the cargo box 400, and the transportation cart 100 transports the cargo box 400 to transport the articles, which is not limited in the present disclosure.

In the present disclosure, the number and arrangement positions of the rails 200 may be set as desired. For example, depending on the size of the building 1000, multiple tracks 200 may be provided and the number of tracks 200 may be reasonably arranged to facilitate the receipt and delivery of goods by users at various locations within the building 1000.

When the above-described cargo conveying system is provided in a building 1000, in one embodiment of the present disclosure, as shown in fig. 1, a hoistway 500 may be provided in the building 1000 to arrange the rails 200, the hoistway 500 being provided to facilitate mounting of the rails 200 on the one hand. For example, the track 200 may be disposed on an inner wall of the hoistway 500; on the other hand, the goods are transported in a relatively closed environment, so that the influence of the transport trolley 100 on the outside of the hoistway 500 is reduced, for example, the noise is reduced.

In other embodiments of the present disclosure, the corresponding hoistway 500 may not be provided in the building 1000, and at this time, the track 200 may be disposed on a wall of the building 1000.

In addition, in order to enable a single track 200 to correspond to as many users as possible, the track 200 may be disposed at a location adjacent to a plurality of users, such as the center of the building 1000, or between two balconies of the outer walls of the building 1000.

As shown in fig. 1, in one embodiment of the present disclosure, track 200 has Z-track 200 segments. The transportation cart 100 has a first position and a second position located below the first position on the Z-direction track 200, and in the first position, the object carrying surface 211 is higher than the placing surface 310, so that the cargo can be moved above the placing surface 310 when the telescopic arm 21 moves in the Y-direction. Thus, when the transport vehicle 100 is moved to the first position, the telescopic arms 21 can transfer the cargo (cargo box 400) located thereon to the cargo receiving and dispatching platform if there is a need for unloading. In the second position, the upper end of the first Z-direction projection 22 is not higher than the placement surface 310 to avoid the cargo (the cargo box 400), so that when the telescopic arm 21 retracts, the first Z-direction projection 22 does not interfere with the cargo and can retract smoothly. Thus, when the trolley is moved to the second position, the telescopic arm 21 can be retracted smoothly after the unloading of the cargo is completed.

So, utilize travelling bogie 100 to reciprocate along Z on track 200 for it need not to set up on telescopic boom 21 like branch goods shift fork back-out and back-forth in first Z to protruding 22, also can realize spacing and dodging to the goods, can reduce travelling bogie 100's power supply quantity, thereby is favorable to simplifying mechanical structure, power supply wiring.

Optionally, as shown in fig. 4 and 7, a first point P1 and a second point P2 are provided on the Z-direction track 200 segment at intervals along the Z-direction, wherein the first point P1 is located above the second point P2, and the transportation cart 100 is provided with an identification point P3. As shown in fig. 5, when the identification point P3 is aligned with the first point P1 in the Z direction of the Z-direction track 200 (the identification program may be provided in the transportation cart 100 to perform determination in conjunction with a hardware device such as a sensor), the transportation cart 100 is at the first position. As shown in FIG. 5, the transport vehicle 100 is in the second position when the identification point P3 is aligned with the second point P2 in the Z-direction of the Z-direction track 200 segment.

In the present disclosure, the number of the cargo-transceiving stations 300 is not limited. As shown in fig. 1, in an embodiment of the present disclosure, there may be at least two cargo receiving/dispatching stations 300 on the single track 200, where the at least two cargo receiving/dispatching stations 300 are oppositely disposed on two sides of the track 200 in the Y direction, that is, the two cargo receiving/dispatching stations 300 are respectively disposed on two sides of the track 200 in the width direction, and the telescopic arm 21 can be bi-directionally telescopic in the Y direction, so that the telescopic arm 21 can load or unload cargos from the two cargo receiving/dispatching stations 300 respectively. Due to the arrangement of the two cargo receiving and dispatching stations 300, users at different positions of the building 1000 can conveniently select the suitable cargo receiving and dispatching stations 300 to receive and dispatch cargos according to factors such as distance. Moreover, the telescopic arm 21 is configured to be bi-directionally telescopic to correspond to the two cargo-receiving stations 300, which is advantageous for reducing the number of the rails 200, thereby reducing the space occupied inside the building 1000.

In another embodiment, a single rail 200 may simultaneously correspond to three cargo receiving/dispatching stations 300, in which case, two cargo receiving/dispatching stations 300 may be respectively disposed at both sides of the rail 200 in the width direction, the remaining one cargo receiving/dispatching station 300 may be disposed in a direction perpendicular to the rail 200, and the transfer mechanism may be configured to be rotatable about the carriage body 10 so that the extending/retracting direction of the telescopic arm 21 can be adjusted to a direction perpendicular to the rail 200, for example, the X direction in fig. 1.

In order to increase the stroke of the telescopic arm 21 so that the telescopic arm 21 can cover a further working range, the telescopic arm 21 may be extended by a longer distance in one side. In this way, a greater working range can be covered without changing the width of the body of the trolley 100, allowing the cargo-handling platforms to be located further from the track 200, thereby facilitating the number of cargo-handling platforms in a smaller overall building 1000.

Alternatively, in an embodiment of the present disclosure, as shown in fig. 2, 3, 10 and 11, the telescopic arm 21 may be a multi-stage telescopic structure including a multi-stage slide rail 212 capable of sliding relatively. The first Z-direction protrusion 22 and the second Z-direction limiting protrusion 22 may be disposed on the slide rail 212 closest to the cargo receiving and dispatching station 300 when the telescopic arm 21 is in the extended state. In this way, the extension or contraction of the telescopic arm 21 can be realized by the relative sliding between the sliding rails 212 to adapt to the distance between the cargo platform 300 and the transportation cart 100, thereby realizing the loading or unloading of the cargo on the cargo platform 300.

The number of stages of the slide rail 212 is not limited in the present disclosure, and may be any suitable number of stages such as 2, 3, 4, 5, etc., and may be determined according to factors such as the size of the transportation cart 100 and the distance between the transportation cart 100 and the cargo receiving and dispatching platform.

In this embodiment, a driving mechanism may be used to drive the two adjacent sliding rails 212 to slide relatively. The present disclosure is not limited to the specific structure of the driving mechanism, for example, the linear motor 28 may be used to drive the interaction between two adjacent slide rails 212, and specifically, the linear motor 28 may be mounted on a side wall of a next-stage slide rail 212 (e.g., the slide rail 212 close to the stage 24 shown in fig. 10) of the two adjacent slide rails 212, and a push rod of the linear motor 28 may be connected to a side wall of a previous-stage slide rail 212 (e.g., the slide rail 212 far from the stage 24 shown in fig. 10) of the two adjacent slide rails 212, so that the two adjacent slide rails 212 can slide relatively by extending and contracting the push rod.

In other embodiments of the present disclosure, the telescopic arm 21 may be configured as a multi-stage telescopic hydraulic cylinder structure to achieve the telescopic movement. Since the working principle of the multi-stage telescopic hydraulic cylinder is well known to those skilled in the art, it is not described herein in detail.

In another embodiment of the present disclosure, referring to fig. 10, the slide rail 212 may be only one stage, the slide rail 212 may be movably disposed on the shelf 20, and the first Z-direction protrusion 22 and the second Z-direction protrusion 23 are also disposed on the slide rail 212.

The number and specific shape of the telescopic arms 21 are not limited in the present disclosure. As shown in fig. 10 and 11, in an embodiment of the present disclosure, the number of the telescopic arms 21 may be two, and the two telescopic arms 21 are spaced apart in the X direction. The telescopic arms 21 are arranged to reduce the width of each telescopic arm 21 in the X direction, and each telescopic arm 21 may be a strip-shaped structure extending substantially in the Y direction. In the embodiment shown in fig. 10 and 11, when the telescopic arm 21 is formed by a plurality of stages of slide rails 212, each slide rail 212 has a strip-shaped structure extending in the Y direction.

It is understood that in other embodiments of the present disclosure, there may be only one telescopic arm 21, and in this case, the size of the telescopic arm 21 in the X direction may be increased appropriately, so as to support the cargo or the cargo box 400 well.

The present disclosure is not limited to the specific configuration of the shelf 20. Alternatively, as shown in fig. 2, 10 and 11, in an embodiment of the present disclosure, the shelf 20 may include a carrier 24, a bracket 25, and a driving device, the bracket 25 is fixed to the cart body 10, the telescopic arm 21 is disposed on the carrier 24, the carrier 24 is rotatably connected to the bracket 25, and the driving device is configured to drive the carrier 24 to rotate relative to the bracket 25, so that the carrier surface 211 of the carrier 24 is always located on the upper surface of the carrier 24 when the transportation cart 100 travels, that is, the carrier surface 211 always faces the forward direction of the Z direction when the transportation cart 100 travels. Thus, as shown in fig. 10 and 11, when the transportation cart 100 travels on the track 200 at different angles from the vertical direction (for example, when switching between the Z-direction track section 210 and the horizontal track section 220 of the track 200, especially when passing through a curved track therebetween), the upward attitude of the cargo on the loading surface 211 is also ensured to be unchanged, that is, the cargo is always kept in a horizontal state, so that the cargo is not easily dropped from the loading surface 211.

In one embodiment of the present disclosure, the rail 200 may be formed in a tank structure, and a stopper plate perpendicular to both side walls of the tank is formed at both side walls of the tank, and the wheel 11 of the transporting carriage 100 may be accommodated between the stopper plate and a bottom plate of the tank structure, so that the transporting carriage 100 may be prevented from falling off the rail 200.

In addition, in other embodiments, when the transportation cart 100 does not adopt a wheel structure, but uses the chassis of the transportation cart 100 to mate with the rail 200, the rail 200 may be formed in a groove-shaped structure, stop plates perpendicular to the side walls are formed on both side walls of the groove body, a guide groove for receiving the stop plates may be formed on the chassis, and the stop plates of the rail 200 are embedded in the guide groove of the chassis, so that the chassis can slide along the rail 200 and cannot be separated from the chassis. Alternatively, in other embodiments of the present disclosure, a T-shaped slider may be disposed on the chassis, and the track 200 is formed as a sliding chute with a T-shaped cross section, so that the T-shaped slider is embedded in the T-shaped sliding chute, which can not only keep the chassis running, but also prevent the chassis from coming off.

In one embodiment of the present disclosure, the wheels 11 of the transportation cart 100 and the rail 200 may be in a close-fit sliding fit, the transportation cart 100 may be a self-driven cart, such as an electrically controlled cart, and when the transportation cart 100 is driven, the driving force generated by the transportation cart 100 is greater than the friction force between the wheels 11 and the rail 200, so that the cart runs along the rail 200; when the transportation cart 100 is stopped, the friction generated between the wheels 11 and the rail 200 can keep the cart in a stationary position, for example, the friction generated between the wheels 11 and the rail 200 of the transportation cart 100 at a stationary Z-direction rail section 210 of the rail 200 can be greater than the gravity of the transportation cart 100, thereby preventing the transportation cart 100 from falling from the rail 200.

The transportation trolley 100 further comprises a detection device and a controller, wherein the controller is in signal connection with the detection device and the driving device, the detection device is used for detecting the levelness of the object stage 24, and the controller is used for acquiring detection information of the detection device so as to control the operation of the driving device based on the detection information, so that the angle of the object stage 24 relative to the support 25 is adjusted, and the object carrying surface 211 on the object stage 24 is always located on the upper surface of the object stage 24. And the controller may also be used to control the extension and retraction of the telescopic arm 21.

The present disclosure is not limited to a specific type of the detecting device, and the detecting device may be, for example, a level, a sensor, or the like for detecting the levelness of the object-carrying surface 211 of the object-carrying stage 24.

Here, there may be various ways of rotatably coupling the object table 24 to the bracket 25, as shown in fig. 2, in one embodiment of the present disclosure, the bracket 25 may include a pair of first lugs 251 and a hinge shaft 252, the pair of first lugs 251 are oppositely disposed at both sides of the cart body 10, and both ends of the hinge shaft 252 are respectively hinged to the pair of first lugs 251. The object stage 24 is provided with a second lug 243, and the hinge shaft 252 is inserted into the second lug 243, wherein a hinge hole for inserting the hinge shaft 252 may be provided on the lug. Thus, when the hinge shaft 252 rotates around the hinge hole, the object stage 24 can rotate around the first lug 251 along with the hinge shaft 252, so that the object stage 24 can be rotatably connected to the cart body 10.

In other embodiments, referring to fig. 2, a corresponding cylindrical section may be provided on the object stage 24 to form a hinge shaft 252, a hinge hole is provided at a corresponding position on the bracket 25, and the object stage 24 is rotatably engaged in the hinge hole through the hinge shaft 252, so that the object stage 24 and the bracket 25 can be rotated.

Wherein, the motor 28 can be installed on the bracket 25, the first belt pulley 26 is sleeved on the hinge shaft 252, the second belt pulley is sleeved on an output shaft (not shown) of the motor 28, and the transmission belt 27 is in transmission connection with the first belt pulley 26 and the second belt pulley. Thus, the rotation of the motor 28 is controlled, and the rotation of the stage 24 relative to the support 25 can be realized through the transmission mechanism.

In other embodiments, the power transmission of the motor 28 can be realized by engaging two gears to realize the relative rotation of the object stage 24 and the support 25. Specifically, one of the gears may be sleeved on the output shaft of the motor, and the other gear may be sleeved on the hinge shaft 252.

As shown in fig. 2, 10 and 11, in one embodiment of the present disclosure, the stage 24 has a U-shape and includes a second base plate 241 and second side plates 242 disposed at opposite sides of the second base plate 241, the second base plate 241 being connected to the hinge shaft 252, and in particular, a bottom wall of the second base plate 241 being connected to the hinge shaft 252. In this embodiment, the object table 24 is constructed in a U-shaped box structure to facilitate placement of goods or containers 400.

As shown in fig. 2, the telescopic arm 21 is slidably connected to an inner wall of the floor, for example, a guide groove is provided on the inner wall, and a portion of the telescopic arm 21 is slidably connected in the guide groove.

The present disclosure is also not limited to a particular shape or configuration of the cargo receiving/dispatching station 300. Alternatively, as shown in fig. 5, in one embodiment of the present disclosure, the cargo receiving and dispatching station 300 has at least one groove 320, and the telescopic arm 21 can move in the Y direction and the Z direction in the groove 320 to place the cargo on the placing surface 310 from the telescopic arm 21 or transfer the cargo on the placing surface 310 to the telescopic arm 21.

Specifically, as shown in fig. 4 to 9, the process of transferring the cargo from the transporting carriage 100 to the cargo-receiving/dispatching station 300 by the telescopic arm 21 (cargo unloading process) is: first, as shown in fig. 4 and 5, when the transport cart 100 travels on the rails 200 to the first position, the telescopic arm 21 may be extended in the Y direction with the cargo (cargo box 400) so that the cargo is located above the cargo-receiving bay 300, as shown in fig. 5 and 6; then, the transporting carriage 100 moves in the negative direction (downward) in the Z direction and descends to the second position, the telescopic arm 21 moves downward in the groove 320 along the Z direction, at this time, the cargo (the cargo box 400) falls on the cargo receiving and dispatching table 300, and the height of the upper end of the first Z-direction protrusion 22 is lower than that of the placing surface 310 (the bottom surface 410 of the cargo box 400), as shown in fig. 7 and 8; thereafter, the telescopic arm 21 is retracted, completing the unloading operation, as shown in fig. 9.

Conversely, the process of transferring the load from the load receiving and dispatching station 300 to the transport vehicle 100 (loading process) by the telescopic arm 21 is: first, when the transportation cart 100 travels on the rail 200 to the second position, the telescopic arm 21 can be extended in the Y direction; then, the transportation cart 100 moves forward (upward) in the Z direction, and rises to the second position, in which the placing surface 310 of the telescopic arm 21 comes into contact with the cargo and lifts the cargo off the cargo-receiving platform 300; the telescopic arm 21 is then retracted to transfer the cargo onto the original cart's stage 24, completing the loading.

The specific structure and shape of the cargo receiving and dispatching platform 300 are not limited in the present disclosure, and optionally, as shown in fig. 5, the cargo receiving and dispatching platform 300 is U-shaped, and includes a first bottom plate 330 and first side plates 340 disposed on two opposite sides of the first bottom plate 330 in the X direction, a portion of an inner wall of the first bottom plate 330 is recessed downward to form the groove 320, and another portion of an inner wall of the first bottom plate 330 forms the placing surface 310. Thus, the cargo bed 300 is constructed in a U-shaped cargo box 400 structure having a cargo receiving space for conveniently placing cargo or cargo boxes 400. And because the groove 320 is arranged for the telescopic arm 21 to move along the Z direction in the groove 320, the first Z-direction bulge 22 is avoided from the cargo container 400, and the telescopic arm 21 can be smoothly retracted.

As shown in fig. 5, in one mode of the present disclosure, the number of the grooves 320 may be two, so as to correspond to the two telescopic arms 21 of the transfer structure, respectively. Optionally, each groove 320 extends to the inner wall of the first side plate 340 at one side in the X direction.

In other embodiments, if the telescopic arm 21 has one or more telescopic arms 21, such as 3, 4, 5, etc., the number of the grooves 320 may correspond to the number of the telescopic arms 21.

Further, as shown in fig. 5, in one embodiment of the present disclosure, the inner wall of the first side plate 340 is formed with a first guide slope 341 and a second guide slope 342 at both ends in the Y direction, respectively. In the Y direction, the size of the inner wall of the first side plate 340 is smaller than the size of the outer wall of the first side plate 340. In this way, during manual or automatic placement of the container 400, the two guide ramps guide the cargo to define the cargo in the correct position for automatic docking of the telescopic arms 21.

Specifically, due to the first guiding inclined plane 341, when the goods are taken from or placed on the goods receiving and dispatching desk 300, especially when the size of the goods (the goods box 400) is not much different from the goods accommodating space on the goods receiving and dispatching desk 300, the goods (the goods box 400) can conveniently enter or exit the goods accommodating space through the first guiding inclined plane 341 due to the existence of the first guiding inclined plane 341.

Also, as shown in fig. 5, since the second guide slope 342 is provided, it is convenient for the cargo to enter the cargo accommodating space from the telescopic arm 21 or to move from the accommodating space onto the telescopic arm 21.

In one embodiment of the present disclosure, the track 200 may be a live track 200, and the trolley 100 is powered and provides a control signal through the live track 200. Therefore, the power supply and the control signal can be provided for the transport trolley 100 in the walking process of the transport trolley 100, the storage battery does not need to be replaced or the transport trolley 100 does not need to be charged in a special place, and the working efficiency of the transport trolley 100 can be improved.

There are various ways to make the track 200 a live track 200, such as arranging a conductive wire with a plurality of contacts on the track 200, with which the trolley 100 is contacted during walking and thus powered.

In one embodiment of the present disclosure, the small body may be a conventional RGV car or shuttle car, i.e. a driving device is provided in the car body 10, and the transport car 100 can be driven to travel on the track 200 by itself. Since the principles of RGV car and shuttle car walking are well known to those skilled in the art, they will not be described in detail herein.

As mentioned above, in the present disclosure, the transport cart 100 may be used to directly transfer the objects, or a special cargo box 400 may be provided for placing the objects, and the transport cart 100 may transport the objects by transporting the cargo box 400. Since the dimensions of the cargo box 400 may be relatively fixed to facilitate the corresponding arrangement of structures for transporting the cargo box 400, in one embodiment of the present disclosure, as shown in fig. 1-9, the cargo conveying system further includes the cargo box 400. And optionally the dimension of the cargo box 400 in the Y direction is adapted to the separation distance between the first Z-direction protrusion 22 and the second Z-direction protrusion 23. In this way, when the telescopic arm 21 is extended, the second Z-shaped projection 23 can apply a pushing force like the cargo or cargo box 400, so that the cargo or cargo box 400 is synchronously moved toward the cargo transceiving stage 300, which is advantageous for transporting the cargo or cargo box 400 to a precise position. Similarly, when the telescopic arm 21 is retracted, the first Z-projection 22 can apply a pushing force to the cargo or cargo box 400, so that the cargo or cargo box 400 can be moved to a precise position on the transport vehicle 100 synchronously following the telescopic arm 21.

In one embodiment of the present disclosure, the cargo transfer system is a building 1000 cargo transfer system, i.e., the cargo transfer system is a building 1000 cargo transfer system. As shown in fig. 1, the cargo conveying system of the building 1000 is provided with a hoistway 500, a track 200 is provided in the hoistway 500, and an opening 510 through which cargo or a telescopic arm 21 passes is opened in a wall of the hoistway 500.

Optionally, openings are provided on both walls of the hoistway 500 along the Y direction, and central axes of the two openings coincide. In this way, cargo or cargo containers 400 can be transferred through the corresponding openings when the telescopic arms 21 are extended bi-directionally on the transport cart 100.

According to another aspect of the present disclosure, there is provided a transporting carriage 100, the transporting carriage 100 comprising a carriage body 10 and a rack 20, the rack 20 comprising a transfer mechanism for transferring goods from one of the transporting carriage 100 and a target place (such as the goods-transceiving stage 300 described above) to the other, the transfer mechanism comprising a telescopic arm 21, the telescopic arm 21 being telescopic in a direction of delivering and taking the goods, and the telescopic arm 21 having a loading surface 211 for contacting with a bottom surface of the goods. Due to the fact that the transfer mechanism is integrated on the transport trolley 100, goods can be transferred between the transport trolley 100 and a target place through the extension and contraction of the telescopic arm 21.

The transport trolley 100 of the present disclosure may be applied in various scenarios, for example, when applied to a building cargo transfer system, the cargo may be placed on the cargo receiving and dispatching station 300, for example, using a manual or other transfer mechanism, and then picked up by the transfer mechanism 3 of the transport trolley 100 and transported to the destination through the track 200. For example, to a rooftop for unmanned distribution by a drone. Similarly, cargo from the unmanned aerial vehicle can be transported to the interior of the building by the transport vehicle 100. In this way, two-way, fast, unmanned delivery from the drone to the user's home can be achieved.

In addition, compared with the technical scheme that the logistics trolley in the prior art is only used as a transport means and a plurality of horizontal rails and vertical rails which are arranged in a staggered mode are arranged, the transportation mechanism is integrated on the transport trolley 100, so that the number of the rails 200 is reduced, the structure of a cargo conveying system can be simplified, and the occupied space of the rails 200 in the building 1000 is reduced.

Moreover, through the movement of the transportation trolley 100 and the extension and contraction of the telescopic arm 21, the telescopic arm 21 can move in the Y direction and the Z direction, so that the goods can be placed on the placing surface 310 from the telescopic arm 21 or the goods can be transferred to the telescopic arm 21 from the placing surface 310, and the goods can be easily transferred.

According to yet another aspect of the present disclosure, a building 1000 is provided, the building 1000 including the cargo delivery system described above.
