The embodiment of the application provides a cargo handling device, which comprises a bracket, a cargo supporting component and a driving component, wherein the cargo supporting component is in sliding connection with the bracket along a first direction, and comprises at least two supporting plate structures which are sequentially and detachably connected along the first direction; the driving assembly is connected with the cargo supporting assembly and drives the cargo supporting assembly to slide along the first direction. The following will describe in detail.

Fig. 1 is a schematic diagram illustrating a structure of an embodiment of a cargo handling device according to an embodiment of the present application. As shown in fig. 1, the cargo handling device 100 includes a bracket 110, a cargo supporting member 120 slidably connected to the bracket 110 along a first direction (arrow direction in fig. 1), and a driving member 130 connected to the cargo supporting member 120 and driving the cargo supporting member 120 to slide along the first direction. It should be noted that, the cargo supporting assembly 120 is slidably connected to the bracket 110 along the first direction, and it may be that the cargo supporting assembly 120 may be integrally slidable along the first direction relative to the bracket 110, or that a portion of the cargo supporting assembly 120 may be slidable along the first direction relative to the bracket 110, and another portion may be rotatable or movable along other directions relative to the bracket 100.

As shown in fig. 1 and 3, the cargo supporting assembly 120 may include at least two supporting plate structures 121 detachably connected in sequence along the first direction. When the cargo is carried into the vehicle 300 by the cargo carrying device 100, as shown in fig. 2, the cargo carrying device 100 may be moved to the rear of the vehicle 300, and the cargo supporting assembly 120 is driven to slide forward in the first direction by the driving assembly 130, so that a portion of the supporting plate structure 121 near the free end of the cargo supporting assembly 120 is moved into the vehicle 300 and supported at the bottom of the vehicle 300; then, the goods are piled on the supporting plate structure 121 which is entered into the carriage 300 until the supporting plate structure 121 located in the carriage 300 is piled with the goods; thereafter, the cargo support assembly 120 is driven by the driving assembly 130 to continue to slide forward in the first direction, so that a new portion of the support plate structure 121 enters the compartment 300, and the cargo is stacked on the new support plate structure 121, and after the support plate structure 121 is completely moved into the compartment 300, the portion of the support plate structure 121 located in the compartment can be separated from other support plate structures 121 on the cargo handling device 100. Therefore, the goods can be carried into the carriage 300 outside the carriage 300, and a carrier or carrying equipment is not required to enter the carriage 300, so that the carrying efficiency of the goods is improved.

On the contrary, when the cargo in the compartment 300 needs to be carried out, only the supporting plate structure 121 on the cargo carrying device 100 is connected with the supporting plate structure 121 in the compartment 300, and then the driving assembly 130 drives the supporting plate structure 121 to slide reversely along the first direction so as to pull out the supporting plate structure 121 in the compartment 300, thereby carrying and unloading the cargo 200 in the compartment 300 outside the compartment 300. Thus, there is no need for a carrier or a handling device to enter the interior of the vehicle cabin 300, and the handling efficiency of the cargo 200 is improved.

Further, by directly moving the support plate structure 121 in which the goods 200 are stacked into the vehicle cabin 300, there is no need to improve the structure in the vehicle cabin 300, and the cost of the vehicle cabin 300 is reduced.

In summary, the cargo handling device 100 provided in the embodiment of the present application does not need a carrier or handling equipment to enter the carriage 300, and can be used for transporting the cargo 200 into the carriage 300, or the cargo 200 in the carriage 300 is discharged, so that the operation is safe and convenient, the handling efficiency of the cargo 200 is improved, the overall duration of transporting the cargo 200 by a vehicle is shortened, and the transportation efficiency of the cargo 200 is improved.

It should be noted that, when the cargo supporting assembly 120 includes only two supporting plate structures 121, the width of the two supporting plate structures 121 in the first direction may be slightly smaller than the length of the interior of the cabin 300, so that the cargo may be stacked on only one supporting plate structure 121 and pushed into the cabin 300, and when three or more supporting plate structures 121 of the cargo supporting assembly 120 are included, the cargo may be stacked on a portion of the supporting plate structures 121 and pushed into the cabin 300.

Alternatively, as shown in fig. 4, the supporting plate structure 121 may include a supporting plate 1211 and a connecting piece 1212 connected to the supporting plate 1211, where the connecting pieces 1212 of the at least two supporting plate structures 121 are sequentially detachably connected to form a connecting strap 1213. The driving assembly 130 includes a driving wheel 133 rotatably connected to the bracket 110, and the driving wheel 133 is connected to the connecting belt 1213 and drives the connecting belt 1213 to slide along the first direction, so that the connecting belt 1213 drives the cargo bracket assembly 120 to slide along the first direction as a whole.

It will be appreciated that by detachably connecting the plurality of connecting pieces 1212 in sequence to form the connecting strap 1213, when the connecting piece 1212 of the support plate structure 121 on the load handling apparatus 100 that is entered into the cabin 300 is separated from the connecting piece 1212 of the support plate structure 121 that is not entered into the cabin 300, the driving wheel 133 can be connected to the connecting piece 1212 of the remaining support plate structure 121 on the load handling apparatus 100 and drive the remaining support plate structure 121 to slide in the first direction so as to drive the remaining support plate structure 121 to move into the cabin 300, or, after the remaining support plate structure 121 is connected to the support plate structure 121 in the cabin 300, pull the support plate structure 121 in the cabin 300 out of the cabin 300.

As shown in fig. 3 and 5, the driving assembly 130 may further include a first driving mechanism 131, where the first driving mechanism 131 is connected to the driving wheel 133 and drives the driving wheel 133 to rotate. Thereby, the driving wheel 133 can be more easily caused to drive the cargo support assembly 120 to move in the first direction. There are various ways in which the first driving mechanism 131 drives the driving wheel 133 to rotate, which is not limited herein.

Specifically, for example, the first driving mechanism 131 may include a first driving motor 1311, the first driving motor 1311 is mounted on the bracket 110, a rotation axis of a rotation shaft of the first driving motor 1311 is consistent with a rotation axis of the driving wheel 133, a first driving sprocket 1312 is mounted on the rotation shaft of the first driving motor 1311, a second driving sprocket 1331 is coaxially connected to the driving wheel 133, and the first driving sprocket 1312 and the second driving sprocket 1331 are connected through a first driving chain 1313, so that the first driving motor 1311 drives the driving wheel 133 to rotate forward or backward through the first driving chain 1313.

Alternatively, a first pulley is mounted on the rotation shaft of the first driving motor 1311, and a second pulley is coaxially connected to the driving wheel 133, and the first pulley and the second pulley are connected by a first belt so that the first driving motor 1311 drives the driving wheel 133 to rotate forward or backward by the first pulley.

Further, a first gear may be attached to the rotation shaft of the first driving motor 1311, and a second gear may be coaxially connected to the driving wheel 133, so that the first driving motor 1311 may drive the driving wheel 133 to rotate in the forward or reverse direction by meshing the first gear and the second gear.

In other embodiments, the driving wheel 133 may be manually driven to rotate forward or backward, so as to drive the cargo supporting assembly 120 to slide forward or backward along the first direction.

Alternatively, the connecting element 1212 may include links, and the links of the at least two support plate structures 121 are detachably connected in sequence to form a chain; correspondingly, the driving wheel 133 comprises a sprocket wheel which engages with a chain to make the connection of the driving wheel 133 with the connecting belt 1213 more stable and convenient.

Alternatively, the connecting piece 1212 of the at least two supporting plate structures 121 is provided with a bar-shaped tooth structure on a side opposite to the driving wheel 133, and the connecting pieces 1212 of the at least two supporting plate structures 121 are detachably connected in sequence to form a synchronous belt. Correspondingly, the driving wheel 133 is a synchronous pulley, and the synchronous pulley is meshed with the synchronous belt to drive the cargo supporting assembly 120 to slide in the forward direction or the reverse direction along the first direction.

Optionally, as shown in FIG. 3, the connectors 1212 are positioned at the ends of the support plate 1211 in the length direction to facilitate connection and disconnection between two adjacent connectors 1212.

Wherein, the two ends of the supporting plate 1211 of the supporting plate structure may be connected with the connecting pieces 1212, and the connecting pieces 1212 at the two ends of the supporting plate 1211 of the at least two supporting plate structures 121 are detachably connected in sequence to form two connecting bands 1213, the number of the driving wheels 133 is two, and the two driving wheels 133 are respectively connected with the two connecting bands 1213, and by controlling the two driving wheels 133 to rotate forward or reverse at the same time, the two connecting bands 1213 can be driven to slide forward or reverse along the first direction.

The two driving wheels 133 may be coaxially connected through a connecting shaft so that the two driving wheels 133 synchronously rotate forward or reverse, or the two driving wheels 133 may be respectively connected to different first driving mechanisms 131 so that the two driving wheels 133 are driven by different first driving motors 1311 to simultaneously rotate forward or reverse.

Alternatively, as shown in fig. 3, the driving wheel 133 is located below the cargo supporting assembly 120, and the pressing wheel 140 is rotatably connected to the bracket 110, and the rotation axis of the pressing wheel 140 is consistent with the length direction of the supporting plate 1211, and the pressing wheel 140 is located above the driving wheel 133 and is pressed against the upper surface of the cargo supporting assembly 120. Therefore, when the cargo supporting assembly 120 slides along the first direction, the pressing wheel 140 rolls on the upper surface of the cargo supporting assembly 120, so as to prevent the cargo supporting assembly 120 from moving in the up-down direction, and improve the stability of the cargo handling device 100 when handling the cargo.

It should be noted that, the rotation axis of the puck 140 is consistent with the length direction of the support plate 1211, or the rotation axis of the puck 140 may be parallel to the length direction of the support plate 1211, or the rotation axis of the puck 140 may be inclined at a small angle with respect to the length direction of the support plate 1211, and only when the cargo supporting assembly 120 slides along the first direction, the puck 140 may abut against the upper surface of the cargo supporting assembly 120 and roll along the first direction with respect to the cargo supporting assembly 120.

Specifically, pinch rollers 140 are disposed on both sides of the support plate 1211 in the length direction, and the number of pinch rollers 140 on each side is two and sequentially distributed along the first direction; the rotation axis of the driving wheel 133 is consistent with the rotation axis of the pressing wheel 140, and the pressing wheel 140 is located right above the corresponding driving wheel 133, so as to improve the limit effect of the pressing wheel 140 and the driving wheel 133 on the cargo supporting assembly 120 in the up-down direction.

Alternatively, as shown in fig. 3 and 4, at least part of the end portion of the support plate 1211 may be rotatably connected with a support roller 1214, and the rotation axis of the support roller 1214 coincides with the length direction of the support plate 1211. When the support plate structure 121 of the cargo support assembly 120 enters the vehicle cabin 300, the support rollers 1214 of the support plate structure 121 can be in rolling connection with the bottom of the vehicle cabin 300, so that friction between the cargo support assembly 120 and the bottom of the vehicle cabin 300 is reduced, and the cargo support assembly 120 can move in the vehicle cabin 300 more conveniently.

Wherein, the support rollers 1214 may be rotatably coupled to both ends of each support plate 1211 to enhance the strength of the cargo support assembly 120. Specifically, the cargo supporting assembly 120 includes a plurality of supporting plate structures 121 detachably connected in sequence along a first direction, each supporting plate structure 121 includes a supporting plate 1211 having a strip-shaped structure, and links connected to ends of the supporting plate 1211, the supporting plate 1211 has a U-shaped cross section, and an opening of the U-shaped cross section faces the bottom of the vehicle compartment 300 to enhance the strength of the supporting plate 1211. The links of two adjacent support plate structures 121 are rotationally connected by a connecting shaft, and the two links can be separated by pulling out the connecting shaft, so that the two support plate structures 121 are separated. The supporting roller 1214 is sleeved on the connecting shaft, and the supporting roller 1214 is rotatably connected with the connecting shaft.

Optionally, the driving assembly 130 further includes a drum (not shown) rotatably connected to the bracket 110, the rotation axis of the drum coincides with the length direction of the support plate 1211, the cargo support assembly 120 is of a flexible structure, and a first end of the cargo support assembly 120 in a first direction is connected to the drum. Thus, when the cargo handling device 100 is not in use, as shown in fig. 3 and 5, the cargo support assembly 120 may be wound onto the drum by rotating the drum to facilitate storage of the cargo support assembly 120.

Wherein, the cargo supporting assembly 120 is a flexible structure, which connects the plurality of supporting plate structures 121 together by connection, because the links of the chain are rotatably connected together. Alternatively, cargo support assembly 120 may be made of rubber or other flexible material.

Optionally, the drive assembly 130 further includes a second drive mechanism 132 coupled to the spool and driving rotation of the first spool. Thereby, the drum can be rotated (counterclockwise in fig. 3) more easily to wind the cargo support assembly 120 around the drum. The second driving mechanism 132 may drive the spool to rotate in a variety of ways, and is not limited herein.

Specifically, for example, the second driving mechanism 132 may include a second driving motor 1321, the second driving motor 1321 is mounted on the bracket 110, a rotation axis of a rotation shaft of the second driving motor 1321 is consistent with a rotation axis of the spool, a third driving sprocket 1322 is mounted on the rotation shaft of the second driving motor 1321, a fourth driving sprocket 1341 is coaxially connected to the spool, and the third driving sprocket 1322 and the fourth driving sprocket 1341 are connected through a second driving chain 1323, so that the second driving motor 1321 drives the spool to rotate through the second driving chain 1323.

Or, a third belt wheel is installed on the rotating shaft of the second driving motor 1321, a fourth belt wheel is coaxially connected on the winding drum, and the third belt wheel and the fourth belt wheel are connected through a second belt, so that the second driving motor 1321 drives the winding drum to rotate through the second belt wheel

In addition, a third gear may be mounted on the rotation shaft of the second driving motor 1321, a fourth gear may be coaxially connected to the spool, and the third gear and the fourth gear may be meshed to rotate the spool by the second driving motor 1321.

In other embodiments, the drum may be manually driven to rotate, thereby allowing the cargo support assembly 120 to be wound onto the drum.

Alternatively, as shown in fig. 3, the cargo support assembly 120 may be extended from the first side of the bracket 110 at the second end in the first direction, and the driving wheel 133 may be disposed at the first side of the bracket 110. When cargo is being carried into the vehicle 300 by the cargo carrying apparatus 100 or when cargo is being carried out of the vehicle 300, the first side of the bracket 110 may be brought closer to the rear of the vehicle 300 to facilitate entry of the cargo support assembly 120 into the vehicle 300 or to facilitate connection of the support plate structure 121 of the cargo support assembly 120 with the support plate structure 121 in the vehicle 300.

As shown in fig. 3 and 4, a pallet 111 is further extended from the first side edge of the bracket 110 along the first direction, and the pallet 111 is located below the cargo supporting assembly 120 and supports the cargo supporting assembly 120, so that the cargo supporting assembly 120 can be better moved into the vehicle cabin 300. It will be appreciated that, when the cargo handling device 100 moves to the rear of the vehicle 300, a certain gap may exist between the first side edge of the bracket 110 of the cargo handling device 100 and the rear of the vehicle, and by providing the pallet 111 on the first side edge of the bracket 110, the cargo supporting component 120 located on the gap can be supported, so as to avoid the cargo supporting component 120 located on the gap from being recessed downward under the action of the cargo handling gravity.

Optionally, a guide groove (not shown) extending along the first direction may be formed on the pallet 111, and the support roller 1214 on the cargo supporting assembly 120 is located in the guide groove, so that the support roller 1214 on the cargo supporting assembly 120 is guided by the guide groove on the pallet 111, so that the cargo supporting assembly 120 keeps a straight line and horizontal when moving along the first direction.

Specifically, the support rollers 1214 are rotatably connected to both ends of the support plate 1211 of the support plate structure 121 in the length direction, two guide grooves are arranged on the support plate 111 in parallel, the width of each guide groove in the length direction of the support plate 1211 is slightly larger than the width of each support roller 1214 on the rotation axis, and the support rollers 1214 on both sides of the support plate structure 121 are respectively accommodated in the two guide grooves.

Alternatively, the height of the top of the drum may be made smaller than the height of the top of the driving wheel 133. Thus, the cargo supporting assembly 120 extends obliquely downward from the driving wheel 133 to one end of the winding drum, and the winding drum and the cargo supporting assembly 120 wound thereon do not interfere with the handling of the cargo when the cargo is handled on the supporting plate structure 121 or the cargo on the supporting plate structure 121 is handled.

Specifically, the spool is disposed inside the support 110, the driving wheel 133 is disposed at the top of the support 110, the first driving motor 1311 is located right below the driving wheel 133, the second driving motor 1321 is located between the spool and the first driving motor 1311, and the heights of the first driving motor 1311 and the second driving motor 1321 are the same, and the height of the top of the spool is smaller than the height of the top of the second driving motor 1321.

By installing the first and second driving motors 1311 and 1321 in the space between the drum and the driving wheel 133, the utilization of the internal space of the rack 110 is improved, making the structure of the cargo handling device 100 more compact. Wherein, the rotation axes of the driving wheel 133, the rotation shaft of the first driving motor 1311, the rotation shaft of the second driving motor 1321 and the winding drum are parallel.

As shown in fig. 1 and 2, the cargo handling device 100 may further include a transmission assembly 150 for transmitting cargo handling, where the transmission assembly 150 is connected to the bracket 110 and has a transmission direction, and one end of the transmission assembly 150 along the transmission direction is disposed corresponding to the cargo supporting assembly 120. When the cargo in the compartment 300 is carried out by the cargo carrying device 100, the cargo on the supporting plate structure 121 may be carried or transferred to the transferring assembly 150, and then the cargo is carried and transferred to the predetermined position by the transferring assembly 150. Alternatively, when the cargo at the predetermined position is carried into the vehicle 300 by the cargo carrying device 100, the cargo may be carried onto the transfer unit 150, transferred to a position close to the support plate structure 121 by the transfer unit 150, and then carried or transferred onto the support plate structure 121 by the transfer unit 150, and carried into the vehicle 300 by the support plate structure 121.

Alternatively, the transfer assemblies 150 and the cargo support assemblies 120 may be sequentially distributed along the first direction, with the transfer direction of the transfer assemblies 150 being coincident with the first direction. Thus, one end of the transfer assembly 150 along the transfer direction can be abutted with the cargo supporting assembly 120, especially the top of the drum is lower than the top of the driving wheel 133, so that when the cargo supporting assembly 120 extends obliquely downward from the driving wheel 133 to one end of the drum, one end of the transfer assembly 150 along the first direction can approach the cargo supporting assembly 120, so that the cargo on the transfer assembly 150 is transferred onto the cargo supporting assembly 120, or the cargo on the cargo supporting assembly 120 is transferred onto the transfer assembly 150.

Of course, one end of the transfer assembly 150 along the transfer direction may be disposed near a side edge of the cargo support assembly 120 along the length direction of the support plate 1211, so as to facilitate the use of a handling device or a manual handling device to handle the cargo on the cargo transfer assembly 150 to the cargo support assembly 120, or to handle the cargo on the cargo support assembly 120 to the transfer assembly 150.

The conveying assembly 150 may be a conveying belt, a conveying crawler, or a conveying structure formed by sequentially arranging a plurality of conveying rollers in a radial direction of the conveying rollers, which is not limited herein.

As shown in fig. 1 and 2, a robot 112 may be further disposed on the rack 110, the robot 112 being configured to transfer the cargo on the cargo support assembly 120 to the transport assembly 150, and/or the robot 112 being configured to transfer the cargo on the transport assembly 150 to the cargo support assembly 120. It will be appreciated that the transfer of cargo between the transfer assembly 150 and the cargo support assembly 120 by the robotic handling arm 112 avoids the cargo being transferred directly between the transfer assembly 150 and the cargo support assembly 120 and trapped in the gap between the cargo support assembly 120 and the transfer assembly 150. Meanwhile, the cargo handling efficiency between the transfer assembly 150 and the cargo supporting assembly 120 can be improved by the robot handling robot 112.

Specifically, a mounting table 113 is further disposed on the bracket 110, the mounting table 113 is located at a side of the transmission assembly 150 and is disposed near the cargo supporting assembly 120, and the manipulator 112 is mounted on the mounting table 113, so that the manipulator 112 can conveniently carry the cargo on the cargo supporting assembly 120 to the transmission assembly 150, or the manipulator 112 can conveniently carry the cargo on the transmission assembly 150 to the cargo supporting assembly 120 and sequentially stack along a length direction of the supporting plate 1211.

As shown in fig. 1 and 2, the cargo handling device 100 may further include a lifting mechanism 114, where the lifting mechanism 114 is located below the support frame 110 and is connected to the support frame 110 to drive the support frame 110 to lift. Therefore, the height of the bracket 110 can be adjusted according to the height of the carriage 300, so as to adjust the height of the cargo supporting assembly 120 on the bracket 110, thereby improving the application range of the cargo handling device 100.

Specifically, the lifting mechanism 114 includes a base plate 1141, a driving cylinder (not shown), and a first lifting frame 1142 and a second lifting frame 1143 that are connected in a cross-rotation manner, wherein the bottom of the first lifting frame 1142 is connected in a rotation manner to the base plate 1141, the top of the first lifting frame 1142 is hinged to the bracket 110 in a sliding manner, and the top of the first lifting frame 1142 can be close to or far from the top of the second lifting frame 1143 by sliding relative to the bracket 110; the top of the second lift 1143 is rotatably connected to the bracket 110, and the bottom of the second lift 1143 is slidably hinged to the bottom plate 1141, and the bottom of the second lift 1143 can be moved closer to or farther from the bottom of the first lift 1142 by sliding with respect to the bottom plate 1141. One end of the driving cylinder is connected to the first lifter 1142, and the other end is connected to the second lifter 1143, and by controlling the expansion and contraction of the driving cylinder, the first lifter 1142 can be rotated relative to the second lifter 1143, thereby controlling the lifting mechanism 114 to lift as a whole.

Of course, the lifting mechanism 114 may be configured to drive the stand 110 to lift, such as a lifting screw, without limitation.

As shown in fig. 1 and 2, a traveling wheel 115 is further connected to the bottom of the lifting mechanism 114, so that the movement of the cargo handling device 100 is facilitated. Specifically, the number of the traveling wheels 115 is plural, and each traveling wheel is rotatably connected to the bottom plate 1141 of the elevating mechanism 114.
