In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present application.

In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0042] The present application provides an unloading device that is connected to a flexible support plate installed in a vehicle compartment and pulls the flexible support plate out of the compartment, thereby quickly unloading the compartment. A detailed description is provided below.

[0043] like Figure 4 As shown, the unloading device 100 includes a support 110, a reel 120, and a drive mechanism 130. The reel 120 is rotatably connected to the support 110 and is used to connect to a flexible support plate 211 within a compartment 210 of a vehicle 200. The drive mechanism 130 is disposed on the support 110 and is connected to the reel 120 to drive the reel 120 to rotate, causing the reel 120 to pull the flexible support plate 211 out of the compartment 210 in a first direction. The support 110 can be fixed to a platform 300 at the unloading site or directly to the ground.

[0044] Thus, the flexible support plate 211 can be laid on the floor of the compartment 210 first, and then the goods can be stacked on the flexible support plate 211. When the vehicle 200 transports the goods to the designated unloading site, such as Figure 1 As shown, the vehicle 200 can move the rear end of the carriage 210 to a position close to the unloading device 100, and then connect the reel 120 of the unloading device 100 to the flexible support plate 211 in the carriage 210, and then control the driving mechanism 130 to drive the reel 120 to rotate, so that the flexible support plate 211 in the carriage 210 is pulled out by the reel 120 and wound on the reel 120, so that the goods in the carriage 210 are brought out by the flexible support plate 211, so as to quickly complete the unloading of the carriage 210, thereby solving the problem of low efficiency of the existing unloading device 100 in unloading the vehicle 200.

[0045] When the cargo in the carriage 210 is unloaded, the reel 120 can be controlled to rotate in the opposite direction to release the flexible support plate 211, which is then manually pulled into the carriage 210 and laid on the floor of the carriage 210 to facilitate the next stacking of cargo.

[0046] like Figures 2 to 5 As shown, a support structure 111 for supporting the flexible support plate 211 is provided on the bracket 110. Therefore, when the flexible support plate 211 in the compartment 210 is pulled out by the reel 120, the support structure 111 on the bracket 110 can support the flexible support plate 211 and the cargo on the flexible support plate 211, so that the flexible support plate 211 can more stably bring the cargo out of the compartment 210.

[0047] The support structure 111 includes a rolling support assembly 1111 for supporting the flexible support plate 211, and the rotation axis of the rolling support assembly 1111 extends along the length of the reel 120. Therefore, when the flexible support plate is supported on the rolling support assembly 1111 and moves along the first direction on the rolling support assembly 1111, a rolling connection is formed between the rolling support assembly 1111 of the support structure 111 and the flexible support plate 211, which can reduce the friction between the support structure 111 and the flexible support plate 211, allowing the flexible support plate 211 to be pulled out of the carriage 210 more smoothly.

[0048] Optionally, the rolling support assembly 1111 includes a plurality of support rollers 1112 rotatably connected to the bracket 110, and the plurality of support rollers 1112 are sequentially spaced apart along the first direction. The rotation axes of the plurality of support rollers 1112 extend along the length of the reel 120. When the flexible support plate is supported on the plurality of support rollers 1112 of the rolling support assembly 1111 and moves along the first direction, the plurality of support rollers 1112 of the rolling support assembly 1111 and the flexible support plate 211 are in rolling connection, thereby reducing friction between the rolling support assembly 1111 and the flexible support plate 211.

[0049] In other embodiments, the rolling support assembly 1111 includes a conveyor belt and a pulley connected to the conveyor belt, which is rotatably connected to the bracket 110. The rotation axis of the pulley extends along the length of the reel 120. When the flexible support plate is supported on the conveyor belt of the rolling support assembly 1111 and moves in a first direction, the conveyor belt of the rolling support assembly 1111 and the flexible support plate 211 are in rolling contact, thereby reducing friction between the rolling support assembly 1111 and the flexible support plate 211.

[0050] Alternatively, the rolling support assembly 1111 includes a roller rotatably connected to the bracket 110, and the roller rotates with the bracket 110. The rotation axis of the roller extends along the length direction of the reel 120, or the roller is a universal wheel.

[0051] Of course, the support structure 111 may also include a support plate for supporting the flexible support plate 211. When the flexible support plate 211 is supported on the support plate and moves along the first direction on the support plate, a sliding connection is formed between the support plate of the support structure 111 and the flexible support plate 211. The upper surface of the support plate for supporting the flexible support plate 211 may be treated to reduce the roughness of the upper surface of the support plate and reduce the friction between the support plate and the flexible support plate 211.

[0052] like Figure 5 As shown, the support structure 111 is located above the reel 120 to fully utilize the space below the support structure 111, making the unloading device 100 more compact and reducing the overall volume of the unloading device 100. The support structure 111 can be located directly above the reel 120 or offset a certain distance from the reel 120. Of course, when the support structure 111 is located directly above the reel 120, the unloading device 100 becomes even more compact.

[0053] Specifically, rolling support assembly 1111 is positioned above reel 120. The rotational axes of the multiple support rollers 1112 of rolling support assembly 1111 are parallel to the rotational axis of reel 120. The multiple support rollers 1112 of rolling support assembly 1111 are sequentially arranged along a first direction. Adjacent support rollers 1112 are spaced apart. The multiple support rollers 1112 of rolling support assembly 1111 are of the same height.

[0054] like Figure 2 and Figure 6 As shown, the bracket 110 is further provided with a docking plate 112, which is located on the side of the support structure 111 opposite to the first direction. When the vehicle 200 moves the rear end of the carriage 210 to a position close to the unloading device 100, the docking plate 112 can serve as a transition between the support structure 111 and the carriage 210, preventing a large gap between the support structure 111 and the carriage 210, which would cause the flexible support plate 211 to sink downward into the gap between the support structure 111 and the carriage 210 under the action of the weight of the cargo thereon.

[0055] The docking plate 112 is rotatably connected to the bracket 110. The rotation axis of the docking plate 112 forms an angle with the height direction of the bracket 110. When the vehicle 200 does not move the rear end of the carriage 210 close to the unloading device 100, the docking plate 112 can be rotated upward to be retracted. After the vehicle 200 moves the rear end of the carriage 210 close to the unloading device 100, the docking plate 112 can be rotated downward by a certain angle to dock the docking plate 112 with the rear end of the carriage 210. The edge of the docking plate 112 away from the bracket 110 overlaps the rear end of the carriage 210 to dock the docking plate 112 with the rear end of the carriage 210.

[0056] Optionally, the rotation axis of the docking plate 112 extends along the length of the reel 120. Specifically, the docking plate 112 extends along the length of the reel 120, and is provided with hinge shafts 1121 at both ends of the length. The hinge shafts 1121 are hingedly connected to the bracket 110 to enable the docking plate 112 to be rotatably connected to the bracket 110. The docking plate 112 includes a support surface 1122 for supporting the flexible support plate 211, and a lower surface opposite the support surface 1122. A reinforcement portion 1123 is provided on the lower surface of the docking plate 112 to enhance the structural strength of the docking plate 112. The reinforcement portion 1123 is triangular in shape, with one side of the reinforcement portion 1123 extending along the width of the docking plate 112 and connected to the lower surface of the docking plate 112. There are multiple reinforcement portions 1123, and the multiple reinforcement portions 1123 are distributed sequentially along the length of the docking plate 112 to further enhance the structural strength of the reinforcement plate.

[0057] like Figure 1 and Figure 6As shown, a positioning mark 2111 is provided on the flexible support plate 211. The unloading device 100 further includes a detection component 1124 for detecting the positioning mark 2111. The detection component 1124 detects the positioning mark 2111 to detect the position of the flexible support plate 211. The detection component 1124 is provided on the docking plate 112 so that the detection component 1124 can more conveniently detect the positioning mark 2111 on the flexible support plate 211.

[0058] Specifically, a groove 1125 is provided on the support surface 1122 of the docking plate 112, and the detection component 1124 is arranged in the groove 1125 to facilitate the detection of the positioning mark 2111 on the flexible support plate 211 while avoiding the detection component 1124 interfering with the movement of the flexible support plate 211 on the docking plate 112.

[0059] The specific structure of the detection component 1124 can be determined based on the type of the positioning mark 2111 on the flexible support plate 211. For example, if the positioning mark 2111 on the flexible support plate 211 is a pattern, the corresponding detection component 1124 can be a camera. When the camera recognizes the pattern of the positioning mark 2111, the position of the flexible support plate 211 can be determined. Alternatively, if the positioning mark 2111 on the flexible support plate 211 is a magnetic member, the corresponding detection component 1124 can be a Hall effect sensor. When the Hall effect sensor detects the magnetic member, the position of the flexible support plate 211 can be determined.

[0060] like Figure 4 As shown, the bracket 110 includes two opposing limiting plates 113, which are distributed on either side of the support structure 111 along the rotation axis of the reel 120. The limiting plates 113 extend from the upper surface of the support structure 111. Thus, the two limiting plates 113 can limit the position of the flexible support plate 211 on the support structure 111, preventing the flexible support plate 211 from deviating when the reel 120 pulls the flexible support plate 211 in the first direction.

[0061] Specifically, the bracket 110 includes a mounting plate 114 and two limiting plates 113 fixedly connected to the mounting plate 114. The two limiting plates 113 are perpendicular to the mounting plate 114. The reel 120 is located between the two limiting plates 113, and the two ends of the reel 120 are respectively rotatably connected to the two limiting plates 113. The rotation axis of the reel 120 is perpendicular to the two limiting plates 113. The multiple support rollers 1112 of the rolling support assembly 1111 are located between the two limiting plates 113, and the two ends of the multiple support rollers 1112 of the rolling support assembly 1111 are respectively rotatably connected to the two limiting plates 113.

[0062] like Figure 4As shown, the drive mechanism 130 is mounted on the mounting plate 114. The drive mechanism 130 includes a first motor 131, the rotating shaft of which is connected to the reel 120 to drive the reel 120 to rotate. The drive mechanism 130 also includes a reducer 132, the rotating shaft of which is connected to the reel 120 via the reducer 132 to drive the reel 120 to rotate. Specifically, the first motor 131 is mounted on the mounting plate 114. The mounting plate 114 is also provided with a mounting base 133, and the reducer 132 is mounted on the mounting base 133 to ensure a more stable connection between the first motor 131 and the reel 120.

[0063] like Figure 7 As shown, the reel 120 includes two connecting members 121 distributed along its rotation axis, and a plurality of connecting rods 122 connected between the two connecting members 121. The plurality of connecting rods 122 are spaced apart around the rotation axis of the reel 120, and the two connecting members 121 are rotatably connected to the bracket 110. When connecting the reel 120 to the flexible support plate 211, the flexible support plate 211 can be initially wound around one of the connecting rods 122, and then the drive mechanism 130 is used to drive the reel 120 to rotate, causing the reel 120 to wind around the flexible support plate 211, thereby making it easier to wind the flexible support plate 211 around the reel 120.

[0064] Optionally, a connecting structure (not shown) is provided on at least the connecting rod 122. When the reel 120 is connected to the flexible support plate 211, the connecting structure on the connecting rod 122 can be connected to the flexible support plate 211 to facilitate the connection between the flexible support plate 211 and the connecting rod 122.

[0065] Among them, at least one connecting rod 122 has a mounting plane 1221 on its outer peripheral surface, and a mounting hole 1222 is opened on the mounting plane 1221. The connecting structure includes a hook for connecting to the flexible support plate 211, and the hook is inserted into the mounting hole 1222 to connect the connecting structure to the connecting rod 122.

[0066] Specifically, the connecting member 121 is plate-shaped, with the two connecting members 121 facing each other and their surfaces perpendicular to the rotation axis of the reel 120. At least one connecting rod 122 includes a connecting portion extending along the rotation axis of the reel 120. The connecting portion has a rectangular cross-section and a side surface of the connecting portion that defines a mounting plane 1221. Mounting holes 1222 are defined at both ends of the mounting plane 1221 along the rotation axis of the reel 120, and a hook is connected to each mounting hole 1222.

[0067] In other embodiments, Figure 8As shown, the reel 120a includes two connecting members 121a distributed along its rotation axis, and a connecting tube 123 connected between the two connecting members 121a. The outer circumference of the connecting tube 123 is provided with a connecting hole 1231, and the inner wall of the connecting hole 1231 along one side of the circumference of the connecting tube 123 is provided with a hanging ear 1232. As a result, a hook can be provided on the flexible support plate 211. When the flexible support plate 211 needs to be wound on the reel 120, the hook on the flexible support plate 211 is hung on the hanging ear 1232, making the connection between the flexible support plate 211 and the reel 120 more convenient.

[0068] The outer circumference of the connecting tube 123 is provided with a plurality of connecting holes 1231, which are distributed sequentially along the length of the connecting tube 123. Accordingly, a plurality of hooks can be provided on the flexible support plate 211, and the hooks on the flexible support plate 211 can be hooked onto corresponding hooks 1232. When the reel 120 pulls the flexible support plate 211 in the first direction, the pulling force applied by the reel 120 to the flexible support plate 211 is relatively evenly distributed along the rotation axis of the reel 120.

[0069] Optionally, connection holes 1231 are provided at both ends of the connection cylinder 123 and in the middle of the connection cylinder 123 so that the pulling force applied by the reel 120 to the flexible support plate 211 is more evenly distributed on the rotation axis of the reel 120 .

[0070] Optionally, the lugs 1232 in at least two connection holes 1231 are located on inner walls on different sides, thereby making the connection between the flexible support plate 211 and the reel 120 more stable.

[0071] Specifically, three connection holes 1231 are formed on the outer circumference of the connecting tube 123, distributed sequentially along the rotation axis of the reel 120. One connection hole 1231 is located in the middle of the connecting tube 123, and the other two connection holes 1231 are located at either end of the connecting tube 123. The connection hole 1231 in the middle of the connecting tube 123 is provided with a hook 1232 on the inner wall along the clockwise side of the connecting tube 123, while the connection holes 1231 at the opposite ends of the connecting tube 123 are also provided with a hook 1232 on the inner wall along the counterclockwise side of the connecting tube 123.

[0072] like Figure 4 and Figure 5 As shown, the bracket 110 is also provided with a length sensor 115, which is used to detect the distance that the reel 120 pulls the flexible support plate 211 along the first direction. Therefore, when the reel 120 pulls the flexible support plate 211 out of the carriage 210, the reel 120 can be promptly controlled to stop rotating.

[0073] The length sensor 115 is disposed on the mounting plate 114 , which is arranged on the corresponding reel 120 , so that the installation of the length sensor 115 is more convenient.

[0074] Optionally, the length sensor 115 includes a meter counter. Specifically, the length sensor 115 includes a support base 1151 provided on the mounting plate 114, a detection wheel 1152 rotatably connected to the support base 1151, and an angle sensor (not shown) connected to the support base 1151 and used to detect the rotation angle of the detection wheel 1152. The rotation axis of the detection wheel 1152 extends along the length direction of the reel 120 and is located on one side of the reel 120 along the first direction. When the reel 120 is connected to the flexible support plate 211, the detection wheel 1152 rolls and abuts against the flexible support plate 211.

[0075] Two guide rollers 119 are spaced apart and disposed on one side of the reel 120 along the first direction. The rotation axes of the two guide rollers 119 extend along the length of the reel 120. A flexible support plate 211 passes through the gap between the two guide rollers 119 and is connected to the reel 120. The detection wheel 1152 of the length sensor 115 is located between the reel 120 and the two guide rollers 119.

[0076] like Figure 2 、 Figure 3 As shown, a protective frame 116 is provided on the bracket 110. The protective frame 116 includes two opposing protective plates 1161. The two protective plates 1161 are distributed on both sides of the support structure 111 along the rotation axis of the reel 120, and the two protective plates 1161 extend from the upper surface of the support structure 111. Therefore, when the flexible support plate 211 moves the cargo onto the support structure 111, the two protective plates 1161 can prevent the cargo on the flexible support plate 211 on the support structure 111 from falling off the two sides of the support structure 111 along the rotation axis of the reel 120.

[0077] Among them, the two protective plates 1161 are respectively connected to side plates 1162 on the opposite side of the first direction, and the distance between the two side plates 1162 gradually decreases in the first direction, so that the rear end of the carriage 210 can enter between the two side plates 1162, so that the rear end of the carriage 210 can be docked with the unloading device 100.

[0078] Alternatively, the distance between the two protective plates 1161 may be gradually reduced in the first direction so that the rear end of the carriage 210 can enter between the two protective plates 1161 and dock with the unloading device 100 .

[0079] Optionally, at least part of the protective plate 1161 is made of transparent material, so that the unloading personnel can observe the status of the goods on the unloading device 100 through the protective plate 1161.

[0080] The two protective plates 1161 can be made of transparent material. Specifically, the two protective plates 1161 and the two side plates 1162 are made of acrylic plates, so that the protective plates 1161 and the side plates 1162 have good transparency and high strength.

[0081] As shown in Figure 2 , Figure 3 , the two protective plates 1161 are connected by a crossbeam 1163 away from the top of the support 110, so that the structure of the two protective plates 1161 is more stable. A curtain 117 is provided on the crossbeam 1163 and extends along the length direction of the crossbeam 1163. When the flexible support plate 211 takes out the goods in the carriage 210, the curtain 117 can make the goods in multiple layers be transported in layers, so as to buffer and delay the goods and prevent the goods from falling and being damaged.

[0082] Specifically, the curtain includes a plurality of flexible long strip plates 1171 extending along the length direction of the winding drum 120. The upper end of the flexible long strip plate 1171 is connected with the crossbeam 1163, and the lower end of the flexible long strip plate 1171 is spaced apart from the upper surface of the support structure 111.

[0083] As shown in Figure 2 , Figure 3 , a transmission assembly 118 is further provided on one side of the support structure 111 along the first direction, and the transmission direction of the transmission assembly 118 is consistent with the first direction. When the flexible support plate 211 takes out the goods in the carriage 210, the goods will be quickly transferred to the transmission assembly 118 and be transmitted to a certain position by the transmission assembly 118, so as to further improve the unloading efficiency of the unloading device 100.

[0084] In other embodiments, the goods taken out from the carriage 210 by the flexible support plate 211 can be carried down by a mechanical handling hand or manually.

[0085] As shown in Figure 3 , Figure 9 , the unloading device 100 includes a moving mechanism 140 connected with the support 110 and driving the support 110 to move along the rotation axis of the winding drum 120. Thus, when the vehicle 200 moves the tail of the carriage 210 to a position close to the unloading device 100, the support 110 can be driven by the moving mechanism 140 to move along the rotation axis of the winding drum 120, and then the winding drum 120 is driven to move along the length direction of itself, so that the positioning of the winding drum 120 and the tail of the carriage 210 is more accurate, and the winding drum 120 and the flexible support plate 211 in the carriage 210 are connected and smoothly pulled out.

[0086] The moving mechanism 140 includes a slide rail 141, a support 142, and a driving structure 143. The slide rail 141 extends along the rotation axis of the winding drum 120. The support 142 is slidably connected with the slide rail 141 along the rotation axis of the winding drum 120. The support 142 is connected with the support frame 110. The driving structure 143 is connected with the support 142 to drive the support 142 to slide along the extension direction of the slide rail 141. Thus, the slide rail 141 of the unloading device 100 can be installed on the ground or the platform 300. By controlling the support 142 to slide along the slide rail 141 through the driving structure 143, the support frame 110 can be driven to move along the rotation axis of the winding drum 120, and the winding drum 120 can be controlled to move along the length direction of the winding drum 120.

[0087] Specifically, the driving structure 143 includes a screw rod (not shown in the figure) extending along the length direction of the slide rail 141, a second motor 1431 connected with the screw rod to drive the screw rod to rotate, and the support 142 is threadedly connected with the screw rod (not shown in the figure). The second motor 1431 drives the screw rod to rotate, and the screw rod drives the support 142 to slide along the slide rail 141.

[0088] In other embodiments, the driving structure 143 includes a driving cylinder (not shown in the figure). One end of the driving cylinder is connected with the slide rail 141, and the other end of the driving cylinder is connected with the support 142. The driving cylinder extends along the length direction of the slide rail 141. By controlling the driving cylinder to extend or retract, the support 142 can be controlled to slide along the slide rail 141. The driving cylinder includes an electric cylinder, a hydraulic cylinder, a pneumatic cylinder, etc., which are not limited herein.

[0089] In other embodiments, the winding drum 120 is slidably connected with the support frame 110 along the rotation axis of the winding drum 120. Thus, the winding drum 120 can be manually or controlled by the moving mechanism 140 to slide along the rotation axis of the winding drum 120.

[0090] The unloading device 100 further includes a moving mechanism 140 (not shown in the figure) connected with the support frame 110. The moving mechanism 140 is rotationally connected with the winding drum 120 to drive the winding drum 120 to slide along the rotation axis of the winding drum 120.

[0091] Specifically, the winding drum 120 comprises a connecting shaft rotatably connected with the support 110, and the connecting shaft is slidingly connected with the support 110 along the length direction of the rotating shaft. A limiting portion (not shown in the figure) is arranged on the outer circumferential surface of the connecting shaft. The moving mechanism 140 comprises a connecting portion (not shown in the figure) rotatably connected with the connecting shaft, and the connecting portion cooperates with the limiting portion to prevent the connecting portion from moving along the length direction of the connecting shaft. The moving mechanism 140 further comprises a driving cylinder, one end of the driving cylinder is connected with the connecting portion, the other end of the driving cylinder is connected with the support 110, and the driving cylinder extends along the length direction of the connecting shaft. By controlling the extension and retraction of the driving cylinder, the movement of the connecting portion along the length direction of the connecting shaft can be controlled, and the rotating shaft is further driven to slide along the length direction of the rotating shaft. The driving cylinder comprises an electric cylinder, a hydraulic cylinder, a pneumatic cylinder and the like, which is not limited here.
