Description

Technical Field

[0001] This disclosure relates to the field of freight transportation, specifically to a transport vehicle, a freight conveying system, and a building. Background Technology

[0002] With the development of logistics technology, the research and application of technologies related to automated delivery of express packages and other goods within buildings are gradually emerging. Existing technical solutions on the market mostly adopt a combination of rail and logistics cart technology. By arranging multiple transport tracks within the building, logistics carts can travel along the tracks, and track-changing devices can connect the logistics carts to different tracks, thus achieving the purpose of receiving and transporting goods.

[0003] In related technologies, multiple intersecting tracks and multiple shafts need to be set up within the building to arrange the tracks, which occupies a large amount of public space in the building, requires significant modifications to the building, and makes the connection between the logistics vehicles and users or equipment for receiving and sending goods complicated. Summary of the Invention

[0004] The purpose of this disclosure is to provide a transport vehicle, a cargo conveying system, and a building, which, when applied to a building, facilitates the conveying of goods while minimizing the space occupied by the building.

[0005] To achieve the above objectives, this disclosure provides a cargo conveying system, including a transport trolley, a track for the transport trolley to travel on, a shaft for arranging the track, and a cargo receiving / dispatching platform for temporarily placing cargo. The transport trolley includes a trolley body and a shelf. The shelf includes a transfer mechanism for transferring cargo from one of the transport trolley and the cargo receiving / dispatching platform to the other. The transfer mechanism includes a telescopic arm. An opening is provided in the wall of the shaft for cargo or the telescopic arm to pass through. The telescopic arm is telescopic in the Y direction and has a loading surface for contacting the bottom surface of the cargo. When the transport trolley moves in the Z direction on the track, it drives the telescopic arm to move in the Z direction to place cargo on the cargo receiving / dispatching platform or transfer cargo from the cargo receiving / dispatching platform to the telescopic arm.

[0006] Optionally, the transfer mechanism further includes a first Z-direction protrusion and a second Z-direction protrusion, both disposed on the telescopic arm. The first Z-direction protrusion is disposed at one end of the telescopic arm near the cargo receiving and dispatching platform, and the second Z-direction protrusion is arranged at a distance from the first Z-direction protrusion in the Y direction.

[0007] Optionally, the cargo receiving and dispatching platform has a placement surface for contacting the bottom surface of the cargo, the track has a Z-direction track segment, and the transport trolley has a first position and a second position located below the first position on the Z-direction track segment. In the first position, the cargo surface is higher than the placement surface, and in the second position, the upper surface of the first Z-direction protrusion is not higher than the placement surface.

[0008] Optionally, there are at least two cargo receiving and dispatching platforms, which are arranged opposite each other on both sides of the track in the Y direction, and the telescopic arm can extend and retract in both directions in the Y direction.

[0009] Optionally, the telescopic arm is a multi-stage telescopic structure, including multi-stage slide rails that can slide relative to each other, and the first Z-direction protrusion is disposed on the slide rail closest to the cargo receiving and dispatching table when the telescopic arm is in the extended state.

[0010] Optionally, the shelf further includes a platform, a support, and a drive device. The support is fixed to the trolley body, the telescopic arm is disposed on the platform, the platform is rotatably connected to the support, and the drive device is used to drive the platform to rotate relative to the support so that the loading surface of the platform is always located on the upper surface of the platform when the transport trolley is moving.

[0011] Optionally, the transport trolley further includes a detection device and a controller. The controller is signal-connected to the detection device and the drive device. The detection device is used to detect the levelness of the platform. The controller is used to acquire the detection information from the detection device to control the operation of the drive device based on the detection information. The controller is also used to control the extension and retraction of the telescopic arm.

[0012] Optionally, the bracket includes a pair of first lugs and a hinge shaft. The pair of first lugs are disposed opposite to each other on both sides of the trolley body. The two ends of the hinge shaft are respectively hinged to the pair of first lugs. A second lug is provided on the platform, and the hinge shaft passes through the second lug.

[0013] Optionally, the driving device includes a motor and a transmission mechanism. The transmission mechanism includes a first pulley, a second pulley, and a transmission belt. The motor is mounted on the bracket. The first pulley is sleeved on the hinge shaft. The second pulley is sleeved on the output shaft of the motor. The transmission belt drivesly connects the first pulley and the second pulley.

[0014] Optionally, the platform is U-shaped and includes a first base plate and first side plates disposed on opposite sides of the first base plate, and the second lug is disposed on the first base plate.

[0015] Optionally, the cargo receiving and dispatching platform has a placement surface for contacting the bottom surface of the cargo and at least one groove, and the telescopic arm is movable in the Z direction within the groove to place the cargo from the telescopic arm onto the placement surface or to transfer the cargo from the placement surface onto the telescopic arm.

[0016] Optionally, the cargo receiving and dispatching platform is U-shaped and includes a second base plate and second side plates disposed on opposite sides of the second base plate in the X direction. A portion of the inner wall of the second base plate is recessed downward to form the groove, and another portion of the inner wall of the second base plate forms the placement surface.

[0017] Optionally, the inner wall of the second side plate has a first guide slope and a second guide slope formed at both ends in the Y direction, wherein the size of the inner wall of the second side plate is smaller than the size of the outer wall of the second side plate in the Y direction.

[0018] Optionally, the track is an electrified track, which supplies power and provides control signals to the transport vehicle.

[0019] Optionally, the cargo conveying system further includes a cargo box for placing cargo, and the transfer mechanism transfers the cargo box from one of the transport trolley and the cargo receiving and dispatching station to the other to realize the transfer of cargo.

[0020] According to another aspect of this disclosure, a transport trolley is provided, the trolley including a trolley body and a rack, the rack including a transfer mechanism for transferring goods from one of the transport trolley and a destination to the other, the transfer mechanism including a telescopic arm extendable in the direction of goods loading, and the telescopic arm having a loading surface for contacting the bottom surface of the goods. According to yet another aspect of this disclosure, a building is provided including the above-described goods conveying system.

[0021] According to another aspect of this disclosure, a building is provided that includes the aforementioned cargo conveying system.

[0022] With the above technical solution, when this cargo conveying system is applied to a building, the transfer mechanism integrated on the transport trolley allows for the transfer of goods between the transport trolley and the cargo receiving / dispatching station via the extension and retraction of the telescopic arm. Compared to existing technologies where logistics trolleys are used solely as transport vehicles and involve numerous staggered horizontal and vertical tracks, this disclosure integrates the transfer mechanism onto the transport trolley, reducing the number of tracks, simplifying the structure of the cargo conveying system, and minimizing the space occupied by the tracks within the building.

[0023] Furthermore, reducing the number of tracks reduces the number of shafts, thus minimizing the space occupied by the entire cargo transport system within the building. Additionally, setting up cargo receiving and dispatching stations within the building provides temporary storage for loading and unloading goods for transport vehicles without requiring significant alterations to the building's internal structure, thereby minimizing the encroachment and modification of users' home space.

[0024] In addition, by moving the transport trolley and extending and retracting the telescopic arm, the telescopic arm can be moved in the Y and Z directions, thereby enabling the goods to be placed on the placement surface from the telescopic arm or transferred from the placement surface to the telescopic arm, making the transfer of goods easy to operate.

[0025] When goods need to be delivered within a building, they can be placed on a receiving platform using manual or other conveying mechanisms. A transport trolley then picks up the goods and transports them to their destination via a track. For example, they can be transported to a rooftop for unmanned drone delivery. Similarly, goods delivered by drones can be transported into the building by the transport trolley. This enables two-way, rapid, and unmanned delivery from drones to users' homes.

[0026] Setting up a shaft facilitates the installation of tracks. For example, tracks can be arranged on the inner wall of the shaft. On the other hand, it creates a relatively enclosed environment for cargo transportation, reducing the impact of transport vehicles on the outside of the shaft, such as reducing noise.

[0027] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0042] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0043] In this disclosure, unless otherwise stated, directional terms such as "up" and "down" generally refer to the orientation defined based on the accompanying drawings. Specifically, "up" and "down" can refer to the same up and down direction of building 1000, that is, the height direction of building 1000, i.e., the Z-direction, as shown in Figure 1. The X, Y, and Z directions are the directions of the three coordinate axes of a three-dimensional coordinate system. "Inner" and "outer" refer to the inner and outer sides of the relevant components. Furthermore, the terms "first," "second," etc., used in the embodiments of this disclosure are for distinguishing one element from another and do not have sequential or importance implications.

[0044] like Figures 1 to 11 As shown, this disclosure provides a cargo conveying system. The cargo conveying system includes a transport trolley 100, a track 200 for the transport trolley 100 to travel on, a shaft 500 for arranging the track 200, and a cargo receiving / dispatching platform 300 for temporarily placing cargo. Wherein, as... Figure 1 As shown, the shaft 500 has an opening 510 on its wall for cargo or the telescopic boom 21 to pass through, such as... Figure 2 and Figure 3 As shown, the transport trolley 100 includes a trolley body 10 and a shelf 20, which has a transfer mechanism for transferring goods from one of the transport trolley 100 and the goods receiving and dispatching station 300 to the other.

[0045] like Figure 10 As shown, the transfer mechanism includes a telescopic arm 21, which is telescopic in the Y direction and has a bottom surface for contacting the cargo (e.g., the bottom surface of the cargo). Figure 2 The bottom surface 410 of the cargo box 400 contacts the loading surface 211. When the transport trolley 100 moves along the Z direction on the track 200, it drives the telescopic arm 21 to move along the Z direction, so as to place the goods on the cargo receiving and dispatching platform 300 or transfer the goods from the cargo receiving and dispatching platform 300 to the telescopic arm 21.

[0046] With the above technical solution, when this cargo conveying system is applied to building 1000, since the transport trolley 100 integrates the aforementioned transfer mechanism, the cargo can be transferred between the transport trolley 100 and the cargo receiving / dispatching table 300 by extending and retracting the telescopic arm 21. Compared to the existing technology where logistics trolleys are only used as transportation tools and involve numerous staggered horizontal and vertical tracks, this disclosure integrates the transfer mechanism onto the transport trolley 100, which helps reduce the number of tracks 200, simplifies the structure of the cargo conveying system, and reduces the space occupied by the tracks 200 within building 1000.

[0047] Furthermore, in the embodiment where the shafts 500 are installed within the building 1000 to arrange the tracks 200, reducing the number of tracks 200 reduces the number of shafts 500, thereby helping to minimize the space occupied by the entire cargo conveying system within the building 1000. Moreover, by providing a cargo receiving and dispatching station 300 within the building 1000 as a temporary warehouse for loading and unloading goods for the transport trolleys 100, no major modifications to the internal structure of the building 1000 are required. Therefore, this method has the advantage of minimizing the encroachment and alteration to users' home space.

[0048] In addition, by moving the transport trolley 100 and extending and retracting the telescopic arm 21, the telescopic arm 21 can be moved in the Y and Z directions, thereby enabling the goods to be placed on the placement surface 310 from the telescopic arm 21 or transferred from the placement surface 310 to the telescopic arm 21, making the transfer of goods easy to operate.

[0049] When goods need to be delivered within building 1000, they can be placed on the goods receiving / dispatching table 300, for example, manually or using other conveying mechanisms. The goods are then picked up by the transfer mechanism of the transport cart 100 and transported to their destination via track 200. For example, they can be transported to the rooftop for unmanned delivery by drones. Similarly, goods delivered by drones can also be transported into building 1000 by the transport cart 100. This enables two-way, rapid, and unmanned delivery from drones to users' homes.

[0050] Setting up the shaft 500 facilitates the installation of the track 200. For example, the track 200 can be arranged on the inner wall of the shaft 500. On the other hand, it allows the transport of goods to be in a relatively enclosed environment, reducing the impact of the transport trolley 100 on the outside of the shaft 500, such as reducing noise.

[0051] like Figure 2 and Figure 3As shown, in one embodiment of this disclosure, the transfer mechanism further includes a first Z-direction protrusion 22 and a second Z-direction protrusion 23, both of which are mounted (installed or integrally formed) on the telescopic arm 21. The first Z-direction protrusion 22 is located at one end of the telescopic arm 21 near the cargo receiving / dispatching table 300, and the second Z-direction protrusion 23 is spaced apart from the first Z-direction protrusion 22 in the Y-direction. Thus, because the first Z-direction protrusion 22 and the second Z-direction protrusion 23 are provided in the telescopic direction of the telescopic arm 21, during the telescopic arm 21's extension and retraction, it can prevent the cargo from slipping or moving on the telescopic arm, thus acting as a limit and preventing the cargo from detaching from the telescopic arm 21 due to movement along the Y-direction. Furthermore, because the first Z-direction protrusion 22 and the second Z-direction protrusion 23 are spaced apart, when the size of the cargo matches the distance between the first Z-direction protrusion 22 and the second Z-direction protrusion 23, such as... Figure 2 As shown, when the telescopic arm 21 extends, the second Z-axis protrusion 23 can apply a pushing force to the goods (such as the cargo box 400), causing the goods to move synchronously toward the cargo receiving and dispatching platform 300, which is beneficial for transporting the goods to a precise position. Similarly, when the telescopic arm 21 retracts, the first Z-axis protrusion 22 can apply a pushing force to the goods (cargo box 400), allowing the goods to move synchronously with the telescopic arm 21 to a precise position on the transport trolley 100.

[0052] In related technologies, the telescopic arm 21 is also equipped with a sorting fork. The sorting fork can be rotated out and back from the telescopic arm 21. When rotated out, the sorting fork acts on the goods to limit their movement and push or pull them so that they follow the telescopic arm 21. When rotated back, the sorting fork releases the goods to place them in the appropriate position. Compared with the scheme using a sorting fork, in the goods conveying system provided in this disclosure, the first Z-direction protrusion 22 and the second Z-direction protrusion 23, while limiting the goods, can eliminate the need for a drive mechanism, such as a motor, to drive the sorting fork to rotate out or back. This reduces the number of power sources, simplifies the mechanical structure and corresponding power supply wiring, reduces the risk of wiring entanglement, and helps to simplify the structure and reliability of the goods conveying system.

[0053] The “first Z-direction protrusion 22 and second Z-direction limiting protrusion 23” here refer to protrusions extending along the Z-direction, that is, protrusions extending along the height direction of the building 1000.

[0054] It is understandable that the "goods" mentioned above can be various specific items such as express delivery or food delivery, or they can be... Figures 1 to 9 The cargo box 400 shown is used to hold various items. That is, specific items can be placed on the telescopic arm 21 for transfer, or specific items can be placed inside the cargo box 400. The transport trolley 100 moves the cargo box 400 to transfer items, and this disclosure does not limit this.

[0055] In this disclosure, the number and arrangement of the tracks 200 can be set as needed. For example, depending on the size of the building 1000, multiple tracks 200 can be set up and the number of tracks 200 can be reasonably arranged to facilitate the receipt and dispatch of goods by users in various places within the building 1000.

[0056] In addition, in order to enable a single track 200 to serve as many users as possible, the track 200 can be arranged in a location adjacent to multiple users, such as the center of building 1000, or between two balconies on the outer wall of building 1000.

[0057] like Figure 1 As shown, in one embodiment of this disclosure, the track 200 has a Z-axis track segment 200. The transport trolley 100 has a first position and a second position below the first position on the Z-axis track segment 200. In the first position, the loading surface 211 is higher than the placement surface 310, so that when the telescopic arm 21 moves in the Y direction, it can move the goods above the placement surface 310. Therefore, when the transport trolley 100 reaches the first position, if there is an unloading requirement, the telescopic arm 21 can transfer the goods (cargo box 400) located thereon to the cargo receiving and unloading platform. In the second position, the upper end of the first Z-axis protrusion 22 is not higher than the placement surface 310 to avoid the goods (cargo box 400), so that when the telescopic arm 21 retracts, the first Z-axis protrusion 22 will not interfere with the goods and can retract smoothly. Therefore, when the trolley reaches the second position, the telescopic arm 21 can retract smoothly after unloading the goods.

[0058] In this way, by utilizing the up-and-down movement of the transport trolley 100 along the Z direction on the track 200, the first Z-direction protrusion 22 does not need to be set on the telescopic arm 21 in the manner of the sorting fork, and the goods can be limited and avoided. This reduces the number of power sources for the transport trolley 100, which is beneficial for simplifying the mechanical structure and power supply wiring.

[0059] Optionally, such as Figure 4 and Figure 7 As shown, a first point P1 and a second point P2 are spaced apart along the Z-axis on the Z-axis track segment 200, with the first point P1 located above the second point P2. A marker point P3 is located on the transport trolley 100. (See diagram below.) Figure 5 As shown, when marker P3 and the first point P1 are aligned in the Z-direction of track segment 200 (a discrimination judgment program can be set in the transport trolley 100 in conjunction with hardware devices such as sensors for judgment), the transport trolley 100 is in the first position. Figure 5 As shown, when the marker point P3 and the second point P2 are aligned in the Z direction of the Z-axis track 200 segment, the transport trolley 100 is in the second position.

[0060] In this disclosure, there is no limitation on the number of cargo receiving and dispatching stations 300. For a single track 200, such as Figure 1 As shown, in one embodiment of this disclosure, there may be at least two cargo receiving / dispatching platforms 300. These at least two platforms 300 are arranged opposite each other on both sides of the track 200 in the Y-direction. That is, the two platforms 300 are located on opposite sides of the track 200 in the width direction. The telescopic arm 21 is bidirectionally extendable in the Y-direction, allowing it to load or unload goods from the two platforms 300 respectively. The arrangement of two platforms 300 facilitates users in different locations within the building 1000 to select the appropriate platform based on factors such as distance for receiving and dispatching goods. Furthermore, configuring the telescopic arm 21 to extend bidirectionally to correspond to the two platforms 300 reduces the number of tracks 200, thereby minimizing the space occupied within the building 1000.

[0061] In other embodiments, a single track 200 can simultaneously correspond to three cargo receiving / dispatching platforms 300. In this case, two cargo receiving / dispatching platforms 300 can be respectively arranged on both sides of the width direction of the track 200, and the remaining cargo receiving / dispatching platform 300 can be arranged in a direction perpendicular to the track 200. Furthermore, the transfer mechanism can be configured to rotate around the trolley body 10, so that the extension / retraction direction of the telescopic arm 21 can be adjusted to be perpendicular to the track 200. For example... Figure 1 The X-direction in the middle.

[0062] To increase the stroke of the telescopic boom 21 and enable it to cover a wider working range, the extension distance of one side of the telescopic boom 21 can be made longer. This allows for a wider working range to be covered without changing the width of the transport trolley 100, and allows the cargo receiving and dispatching platform to be located further away from the track 200, thus reducing the number of cargo receiving and dispatching platforms in the entire building 1000.

[0063] Alternatively, in one embodiment of this disclosure, such as Figure 2 , Figure 3 , Figure 10 and Figure 11 As shown, the telescopic arm 21 can be a multi-stage telescopic structure, including multi-stage slide rails 212 that can slide relative to each other. The first Z-direction protrusion 22 and the second Z-direction limiting protrusion 22 can be disposed on the slide rail 212 closest to the cargo receiving / dispatching platform 300 when the telescopic arm 21 is in the extended state. Thus, the extension or retraction of the telescopic arm 21 can be achieved through the relative sliding between the slide rails 212, adapting to the distance between the cargo receiving / dispatching platform 300 and the transport trolley 100, thereby enabling the loading or unloading of goods on the cargo receiving / dispatching platform 300.

[0064] This disclosure does not limit the number of stages of the slide rail 212, which can be any appropriate number such as 2, 3, 4, or 5, depending on factors such as the size of the transport trolley 100 and the distance between the transport trolley 100 and the cargo receiving and dispatching platform.

[0065] In this embodiment, a drive mechanism can be used to drive relative sliding between two adjacent slide rails 212. This disclosure does not limit the specific structure of the drive mechanism; for example, a linear motor 28 can be used to drive interaction between two adjacent slide rails 212. Specifically, the linear motor 28 can be installed in the next-stage slide rail 212 (e.g., between two adjacent slide rails 212). Figure 10 On the side wall of the slide rail 212 (near the stage 24), the push rod of the linear motor 28 is connected to the previous slide rail 212 (e.g., the first-stage slide rail 212 of the two adjacent slide rails 212). Figure 10 The slide rail 212 (shown as being away from the platform 24) is connected to the side wall, so that relative sliding of two adjacent slide rails 212 can be achieved by extending and retracting the push rod.

[0066] In other embodiments of this disclosure, the telescopic arm 21 may be configured as a multi-stage telescopic hydraulic cylinder to achieve telescopic movement. Since the working principle of a multi-stage telescopic hydraulic cylinder is well known to those skilled in the art, it will not be described in detail here.

[0067] It should be noted that in other embodiments of this disclosure, reference is made to... Figure 10 The slide rail 212 can also be a single-level slide rail 212, which is movably mounted on the shelf 20, and the first Z-direction protrusion 22 and the second Z-direction protrusion 23 are also mounted on the slide rail 212.

[0068] This disclosure does not limit the number or specific shape of the telescopic booms 21. Figure 10 and Figure 11 As shown, in one embodiment of this disclosure, there may be two telescopic arms 21, arranged at intervals along the X direction. Providing two telescopic arms 21 facilitates reducing the width of each telescopic arm 21 in the X direction, and each telescopic arm 21 may be a strip-shaped structure extending approximately along the Y direction. In such a way... Figure 10 and Figure 11 In the embodiment shown, when the telescopic arm 21 is formed by a multi-stage slide rail 212 group, each slide rail 212 has a strip structure extending along the Y direction.

[0069] It is understood that in other embodiments of this disclosure, there may be only one telescopic arm 21. In this case, the size of the telescopic arm 21 in the X direction can be appropriately increased so as to provide better support for the goods or cargo box 400.

[0070] This disclosure does not limit the specific structure of the shelf 20. Optionally, such as Figure 2 , Figure 10and Figure 11 As shown, in one embodiment of this disclosure, the shelf 20 may include a platform 24, a support 25, and a drive device. The support 25 is fixed to the trolley body 10, and the telescopic arm 21 is disposed on the platform 24. The platform 24 is rotatably connected to the support 25. The drive device is used to drive the platform 24 to rotate relative to the support 25, so that when the transport trolley 100 moves, the loading surface 211 of the platform 24 is always located on the upper surface of the platform 24, that is, when the transport trolley 100 moves, the loading surface 211 always faces the positive Z-direction. Thus, as Figure 10 and Figure 11 As shown, when the transport trolley 100 travels on the track 200 at different angles to the vertical direction (for example, when switching between the Z-direction track segment 210 and the horizontal track segment 220 of the track 200, especially when passing through the curved track between the two), it can also ensure that the goods on the loading surface 211 remain in an upward orientation, that is, ensure that the goods are always kept in a horizontal state, so that the goods are not easy to fall off the loading surface 211.

[0071] In one embodiment of this disclosure, the track 200 may be formed as a trough structure, with baffles perpendicular to the side walls of the trough. The wheels 11 of the transport trolley 100 may be accommodated between the baffles and the bottom plate of the trough structure, thereby preventing the transport trolley 100 from falling off the track 200.

[0072] In other embodiments, when the transport trolley 100 does not employ a wheel structure, but instead utilizes the chassis of the transport trolley 100 in conjunction with the track 200, the track 200 can be formed as a groove structure. Perpendicular stop plates are formed on both side walls of the groove, and guide grooves are formed on the chassis to accommodate these stop plates. The stop plates of the track 200 are embedded in the guide grooves of the chassis, allowing the chassis to slide along the track 200 without detaching from it. Alternatively, in other embodiments of this disclosure, a T-shaped slider can be provided on the chassis, and the track 200 is formed as a groove with a T-shaped cross-section, allowing the T-shaped slider to be embedded in the T-shaped groove, thus maintaining the operation of the chassis while preventing it from detaching.

[0073] In one embodiment of this disclosure, the wheels 11 of the transport trolley 100 and the track 200 can be in a sliding fit, and the transport trolley 100 can be a self-driving trolley, such as an electrically controlled trolley. When the transport trolley 100 is driven, the driving force generated by the transport trolley 100 is greater than the friction between the wheels 11 and the track 200, so that the trolley runs along the track 200. When the transport trolley 100 stops, the friction between the wheels 11 and the track 200 can keep the trolley in a stationary position. For example, when the transport trolley 100 is stationary on the Z-direction track segment 210 of the track 200, the friction between its wheels 11 and the track 200 can be greater than the weight of the transport trolley 100, thereby preventing the transport trolley 100 from falling off the track 200.

[0074] The transport trolley 100 also includes a detection device and a controller. The controller is signal-connected to the detection device and the drive device. The detection device is used to detect the levelness of the platform 24, and the controller is used to acquire the detection information from the detection device to control the drive device based on the detection information, thereby adjusting the angle of the platform 24 relative to the support 25 to ensure that the loading surface 211 on the platform 24 is always located on the upper surface of the platform 24. Furthermore, the controller can also be used to control the extension and retraction of the telescopic arm 21.

[0075] This disclosure does not limit the specific type of the detection device. For example, the detection device can be a level, a sensor, etc., to detect the levelness of the loading surface 211 of the stage 24.

[0076] There are several ways to achieve a rotatable connection between the stage 24 and the support 25, such as... Figure 2 As shown, in one embodiment of this disclosure, the bracket 25 may include a pair of first lugs 251 and a hinge shaft 252. The pair of first lugs 251 are disposed opposite to each other on both sides of the trolley body 10, and the two ends of the hinge shaft 252 are respectively hinged to the pair of first lugs 251. The platform 24 is provided with a second lug 243, and the hinge shaft 252 passes through the second lug 243. A hinge hole for inserting the hinge shaft 252 may be provided on the lug. In this way, when the hinge shaft 252 rotates around the hinge hole, the platform 24 can rotate together with the hinge shaft 252 around the first lug 251, so that the platform 24 is rotatably connected to the trolley body 10.

[0077] In other embodiments, refer to Figure 2 A corresponding cylindrical segment can be set on the stage 24 to form a hinge shaft 252, and a hinge hole is opened at the corresponding position on the bracket 25. The stage 24 is rotatably fitted in the hinge hole through the hinge shaft 252, so that the stage 24 and the bracket 25 can rotate.

[0078] This disclosure does not limit the specific structure of the driving device. Optionally, in one embodiment of this disclosure, such as Figure 2 As shown, the drive device includes a motor 28 and a transmission mechanism, which may include a first pulley 26, a second pulley (not shown), and a transmission belt 27. The motor 28 can be mounted on a bracket 25. The first pulley 26 is sleeved on a hinge shaft 252, and the second pulley is sleeved on the output shaft (not shown) of the motor 28. The transmission belt 27 drives the first pulley 26 and the second pulley. Thus, by controlling the rotation of the motor 28, the rotation of the platform 24 relative to the bracket 25 can be achieved through the transmission mechanism.

[0079] In other embodiments, the power transmission of the motor 28 can be achieved by the meshing of two gears, so as to realize the relative rotation between the platform 24 and the bracket 25. Specifically, one gear can be mounted on the output shaft of the motor, and the other gear can be mounted on the hinge shaft 252.

[0080] like Figure 2 , Figure 10 and Figure 11 As shown, in one embodiment of this disclosure, the platform 24 is U-shaped and includes a first base plate 241 and first side plates 242 disposed on opposite sides of the first base plate 241. The first base plate 241 is connected to a hinge shaft 252. Specifically, the bottom wall of the first base plate 241 is connected to the hinge shaft 252. In this embodiment, the platform 24 is constructed as a U-shaped box structure to facilitate the placement of goods or cargo boxes 400.

[0081] like Figure 2 As shown, the telescopic arm 21 is slidably connected to the inner wall of the base plate. For example, a guide groove is provided on the inner wall, and part of the telescopic arm 21 is slidably connected in the guide groove.

[0082] This disclosure does not limit the specific shape and structure of the cargo receiving and dispatching platform 300. Optionally, such as... Figure 5 As shown, in one embodiment of this disclosure, the cargo receiving and dispatching platform 300 has at least one groove 320, and the telescopic arm 21 is movable in the groove 320 along the Y and Z directions to place cargo from the telescopic arm 21 onto the placement surface 310 or to transfer cargo from the placement surface 310 onto the telescopic arm 21.

[0083] Specifically, such as Figures 4 to 9 As shown, the process of the telescopic boom 21 transferring goods from the transport trolley 100 to the goods receiving and dispatching platform 300 (goods unloading process) is as follows: First, as... Figure 4 and Figure 5 As shown, when the transport trolley 100 travels on the track 200 to the first position, the telescopic arm 21 can extend along the Y direction carrying the goods (cargo box 400) so that the goods are positioned above the cargo receiving / dispatching platform 300, as shown. Figure 5 and Figure 6 As shown; then, the transport trolley 100 moves in the negative Z direction (downwards), descending to the second position, and the telescopic arm 21 also moves downwards in the groove 320 along the Z direction. At this time, the goods (cargo box 400) fall onto the cargo receiving and dispatching table 300, and the height of the upper end of the first Z-direction protrusion 22 is lower than the placement surface 310 (the bottom surface 410 of the cargo box 400), as shown. Figure 7 and Figure 8 As shown; then, the telescopic arm 21 retracts, completing the unloading operation, as shown. Figure 9 As shown.

[0084] Conversely, the process of the telescopic arm 21 transferring goods from the cargo receiving and dispatching platform 300 to the transport trolley 100 (loading process) is as follows: First, when the transport trolley 100 travels on the track 200 to the second position, the telescopic arm 21 can be extended along the Y direction; then, the transport trolley 100 moves in the positive direction (upward) along the Z direction and rises to the second position. During this process, the placement surface 310 of the telescopic arm 21 contacts the goods and lifts the goods away from the cargo receiving and dispatching platform 300; afterwards, the telescopic arm 21 retracts to transfer the goods to the loading platform 24 of the original trolley, completing the loading.

[0085] This disclosure does not limit the specific structure and shape of the cargo receiving and dispatching platform 300; alternatively, such as Figure 5 As shown, the cargo receiving and dispatching platform 300 is U-shaped and includes a second base plate 330 and second side plates 340 disposed on opposite sides of the second base plate 330 in the X direction. A portion of the inner wall of the second base plate 330 is recessed downward to form the groove 320, and another portion of the inner wall of the second base plate 330 forms a placement surface 310. Thus, the cargo receiving and dispatching platform 300 is constructed as a U-shaped cargo box 400 structure, providing cargo storage space for easy placement of goods or cargo boxes 400. Furthermore, because the groove 320 allows the telescopic arm 21 to move along the Z direction within the groove 320, the first Z-direction protrusion 22 avoids the cargo box 400, thereby enabling the telescopic arm 21 to retract smoothly.

[0086] like Figure 5 As shown, in one embodiment of this disclosure, there may be two grooves 320, each corresponding to one of the two telescopic arms 21 of the transfer structure. Optionally, each groove 320 extends to the inner wall of the second side plate 340 on one side in the X direction.

[0087] In other embodiments, if the telescopic arm 21 has one, or multiple telescopic arms 21 such as 3, 4, or 5, the number of grooves 320 can correspond to the number of telescopic arms 21.

[0088] In addition, such as Figure 5As shown, in one embodiment of this disclosure, the inner wall of the second side plate 340 has a first guide ramp 341 and a second guide ramp 342 formed at both ends in the Y direction. Specifically, in the Y direction, the size of the inner wall of the second side plate 340 is smaller than the size of the outer wall of the second side plate 340. Thus, during the manual or automatic placement of the cargo box 400, the two guide ramps can guide the cargo to confine it to the correct position where the telescopic arm 21 can automatically dock.

[0089] Specifically, due to the presence of the first guide ramp 341, when goods are picked up or placed from the goods receiving and dispatching platform 300, especially when the size of the goods (cargo box 400) is not much different from the cargo holding space on the goods receiving and dispatching platform 300, the presence of the first guide ramp 341 facilitates the goods (cargo box 400) to enter and exit the cargo holding space through the first guide ramp 341.

[0090] Similarly, as Figure 5 As shown, the second guide ramp 342 facilitates the movement of goods from the telescopic arm 21 into the goods receiving space or from the receiving space onto the telescopic arm 21.

[0091] In one embodiment of this disclosure, the track 200 may be an electrified track 200, which supplies power and control signals to the transport trolley 100. This allows the transport trolley 100 to be powered and controlled while it is in motion, eliminating the need to replace batteries or go to a special location for charging, thus improving the working efficiency of the transport trolley 100.

[0092] There are several ways to make the track 200 an electrified track 200. For example, a conductive line with multiple contacts can be arranged on the track 200. When the transport trolley 100 moves, it comes into contact with the contacts and is thus electrified.

[0093] In one embodiment of this disclosure, the main body can be a conventional RGV trolley or shuttle, that is, the trolley body 10 is equipped with a drive device that can drive the transport trolley 100 to move on the track 200. Since the walking principles of RGV trolleys and shuttles are well known to those skilled in the art, they will not be described in detail here.

[0094] As mentioned above, in this disclosure, a transport trolley 100 can be used to directly transfer goods, or a dedicated cargo box 400 can be set up to hold the goods. The transport trolley 100 achieves the purpose of transporting goods through the cargo box 400. Since the size and specifications of the cargo box 400 can be relatively fixed, it is convenient to set up a corresponding structure to transport the cargo box 400. Therefore, if... Figures 1 to 9As shown, in one embodiment of this disclosure, the cargo conveying system further includes a cargo box 400. Optionally, the Y-axis dimension of the cargo box 400 is adapted to the spacing between the first Z-axis protrusion 22 and the second Z-axis protrusion 23. Thus, when the telescopic arm 21 extends, the second Z-axis protrusion 23 can apply a pushing force to the cargo or cargo box 400, causing the cargo or cargo box 400 to move synchronously toward the cargo receiving / dispatching platform 300, facilitating the transport of the cargo or cargo box 400 to a precise location. Similarly, when the telescopic arm 21 retracts, the first Z-axis protrusion 22 can apply a pushing force to the cargo or cargo box 400, allowing the cargo or cargo box 400 to move synchronously with the telescopic arm 21 to a precise position on the transport trolley 100.

[0095] In one embodiment of this disclosure, the cargo conveying system is a building 1000 cargo conveying system, that is, the cargo conveying system is a cargo conveying system for building 1000. For example... Figure 1 As shown, the building 1000 cargo conveying system is equipped with a shaft 500, and a track 200 is installed inside the shaft 500. An opening 510 is provided on the wall of the shaft 500 for cargo or telescopic arm 21 to pass through.

[0096] Optionally, the shaft 500 has openings on both walls along the Y direction, and the central axes of the two openings coincide. In this way, when the telescopic boom 21 extends bidirectionally on the transport trolley 100, goods or cargo boxes 400 can be transferred through the corresponding openings.

[0097] According to another aspect of this disclosure, a transport trolley 100 is provided, comprising a trolley body 10 and a shelf 20. The shelf 20 includes a transfer mechanism for transferring goods from one of the transport trolley 100 and a destination (such as the goods receiving / dispatching station 300 described above) to the other. The transfer mechanism includes a telescopic arm 21, which is extendable and retractable along the direction of goods loading and has a loading surface 211 for contacting the bottom surface of the goods. Since the transport trolley 100 integrates the aforementioned transfer mechanism, goods can be transferred between the transport trolley 100 and the destination by extending and retracting the telescopic arm 21.

[0098] The transport vehicle 100 disclosed herein can be applied in various scenarios. For example, when applied to a building cargo delivery system, goods can be placed on the cargo receiving and dispatching table 300, for example, manually or by other conveying mechanisms. The goods are then picked up by the transfer mechanism 3 of the transport vehicle 100 and transported to their destination via the track 200. For example, the goods can be transported to the rooftop for unmanned delivery by drones. Similarly, goods delivered by drones can also be transported by the transport vehicle 100 into the building. In this way, bidirectional, fast, and unmanned delivery from drones to users' homes can be realized.

[0099] In addition, compared with the existing technology where logistics vehicles are only used as transportation tools and have a large number of intersecting horizontal and vertical tracks, this disclosure integrates the transfer mechanism on the transport vehicle 100, which helps to reduce the number of tracks 200, simplifies the structure of the cargo conveying system, and reduces the space occupied by the tracks 200 in the building 1000.

[0100] Moreover, by moving the transport trolley 100 and extending and retracting the telescopic arm 21, the telescopic arm 21 can be moved in the Y and Z directions, thereby enabling the goods to be placed on the placement surface 310 from the telescopic arm 21 or transferred from the placement surface 310 to the telescopic arm 21, making the transfer of goods easy to operate.

[0101] According to another aspect of this disclosure, a building 1000 is provided, which includes the aforementioned cargo conveying system.

[0102] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0103] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0104] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
