[0014] One side of the supporting steel plate in the two platform mechanisms is fixedly connected to the side surfaces of the vertical plate and the L-shaped folded plate respectively, and the top surface of one platform mechanism is at the same height as the bottom surface of the other platform mechanism.

[0015] Preferably, a lifting assembly for maintaining the two platform mechanisms in an unfolded state is installed on the front side of the vertical plate.

[0018] 1. The present invention arranges the platform for placing express items into a double-layer stacked form. When unloading the express items, the electric telescopic structure is used to form a staggered arrangement between the upper steel plate and the supporting steel plate. Then, the driving component is used to drive the upper steel plate to rotate through the gear component, so that the express items at various angles on the upper steel plate can be adjusted to the front of the courier, so as to provide convenience when it is necessary to give priority to unloading the express items close to the vertical plate.

[0019] 2. The present invention applies external force to one of the platform mechanisms to cause it to move laterally accordingly, so that the entire trolley can be flexibly adjusted between a single platform and a double platform according to whether it is used and the number of express items required to be loaded.

[0020] 3. When the present invention uses a double platform to load express parcels, an electric push rod is used to drive the connecting plate and baffle plate 1 to move upward, so that baffle plate 1 is attached to one side of the L-shaped folding plate, thereby limiting it and preventing the platform mechanism from moving horizontally for no reason during the transportation of express parcels.

[0021] 4. The present invention continues to operate the electric push rod when the remaining rotation angle of the upper steel plate is less than 90°, driving the second baffle plate to adjust upward to a position at the same height as the upper steel plate, which can play a limiting role in the final rotation stage when the upper layer returns. At the same time, the sensor is used to feedback a signal to the motor structure to stop it immediately, thereby effectively ensuring that the upper steel plate perfectly overlaps with the supporting steel plate when it rotates and returns.

[0035] Embodiment 1

[0036] See also Figure 1-Figure 6 This embodiment proposes an automatic guided trolley for logistics handling, which can meet the needs of multi-directional priority unloading. The trolley has a vertical plate 1 and a guide machine 2 for driving the transport trolley to move and adjust the direction. The guide machine 2 is located at the bottom of the vertical plate 1. It is mainly composed of a rotating drive structure, a travel structure and various types of sensors, which are intended to control the entire trolley to move toward one side and adjust the moving direction as needed. Both sides of the vertical plate 1 are provided with a platform mechanism 3 for placing express items;

[0037] After the express is delivered to the set position by this logistics transport cart, according to the user's needs, the express items on the side close to the vertical plate 1 need to be unloaded first in some cases. Under normal circumstances, the express items on this side are difficult to take out due to the obstruction of the vertical plate 1. In order to effectively solve this problem. Figure 3-Figure 6 As shown, the platform mechanism 3 includes a supporting steel plate 301 installed on the vertical plate 1, an upper steel plate 302 is placed on the top surface of the supporting steel plate 301, a groove 3011 is arranged on the top surface of the supporting steel plate 301, a gear assembly 303 located in the groove 3011 is installed at the bottom of the upper steel plate 302, a protective frame 304 is installed on the side of the supporting steel plate 301, a driving assembly 305 is installed between the protective frame 304 and the groove 3011 for driving the gear assembly 303 to rotate so that the upper steel plate 302 adjusts its direction, and an electric telescopic structure 306 is installed between the inner wall of the protective frame 304 and the driving assembly 305 for staggering the upper steel plate 302 and the supporting steel plate 301 before the upper steel plate 302 rotates. The electric telescopic structure 306 preferably adopts a storage electric telescopic rod. In actual application, the express parcels are normally stacked on the platform mechanism 3. After the trolley moves to the set position, the electric telescopic structure 306 is operated, which pushes the set length to one side accordingly, thereby generating a driving force toward one side for the drive assembly 305, causing the drive assembly 305 to slide toward one side along the groove 3011 and the inside of the protective frame 304 to the set position. At the same time, the gear assembly 303 drives the upper steel plate 302 to move away from the vertical plate 1, so that enough space is reserved between the upper steel plate 302 and the vertical plate 1 for the upper steel plate 302 to rotate. After that, the drive assembly 305 is operated in coordination to cause it to generate a rotational force on the gear assembly 303, thereby driving the upper steel plate 302 to rotate, so that the express parcels at various angles on the upper steel plate 302 can be adjusted in front of the courier.

[0038] Specifically, the driving assembly 305 includes a bearing plate 3051 which is slidably mounted inside the groove 3011, a mounting plate 3052 which is detachably connected to the free end of the electric telescopic structure 306 is integrally mounted at the bottom of the bearing plate 3051, a V-belt 3053 which is meshed with the gear assembly 303 is mounted on the top surface of the bearing plate 3051, a spur gear 3054 which is meshed with the V-belt 3053 is placed on the top surface of the bearing plate 3051, and a motor structure 3055 which is transmission-connected with the spur gear 3054 at the output end is mounted on the mounting plate 3052. In the driving assembly 305, the motor structure 3055 is used as a driving source, and this driving source adopts a storage type, which is convenient for running without a line. By running the motor structure 3055, the spur gear 3054 is controlled to rotate at a low speed, and then the gear assembly 303 is generated with a rotational force through the V-belt 3053, so as to achieve the purpose of driving the upper steel plate 302 which is combined with the local structure in the gear assembly 303 to rotate.

[0039] Embodiment 2

[0040] Under normal circumstances, in order to ensure the convenience of assembling the gear assembly 303 and the drive assembly 305 in the upper steel plate 302 and the supporting steel plate 301, the upper steel plate 302 and the supporting steel plate 301 are usually assembled in a straight-insertion manner. Although this method can ensure the mobility of the upper steel plate 302 when rotating, it is easy to separate from the supporting steel plate 301 when the upper steel plate 302 is pushed from bottom to top. Therefore, in order to effectively ensure the stability of the assembly between the upper steel plate 302 and the supporting steel plate 301. Figure 3-Figure 6 As shown, the gear assembly 303 includes a solid circular plate 3031 fixedly mounted on the top surface of the bearing plate 3051, a positioning circular plate 3032 is placed on the top of the solid circular plate 3031, a locking pin 3033 for fixing the solid circular plate 3031 is installed on the positioning circular plate 3032, a gear ring 3034 whose top surface is in contact with the bottom surface of the upper steel plate 302 is sleeved on the outer surface of the positioning circular plate 3032, and a gear ring 3034 is installed on the inner wall of the gear ring 3034 located below the positioning circular plate 3032. The upper steel plate 302 has a plurality of removable locking pins 3036 extending into the gear ring 3034. The width of the limiting ring 3035 is consistent with the radius difference between the solid circular plate 3031 and the positioning circular plate 3032. The combined height of the solid circular plate 3031 and the positioning circular plate 3032 is lower than the height of the gear ring 3034, thereby effectively avoiding friction on the top surface of the positioning circular plate 3032 when the upper steel plate 302 rotates. When assembling the supporting steel plate 301, the upper steel plate 302, the driving assembly 305 and the gear assembly 303, the bearing plate 3051 with the mounting plate 3052 and the motor structure 3055 in the driving assembly 305 is placed on the bottom wall of the groove 3011, and then the spur gear 3054, the V-belt 3053 and the gear ring 3034 with the limit ring 3035 are installed in sequence, and then the positioning circular plate 3032 and the solid circular plate 3031 are assembled by the locking pin 1 3033. At this time, the positioning circular plate 3032 in a fixed state can effectively prevent the limit ring 3035 and the gear ring 3034 from being separated from the bearing plate 3051. Then, the upper steel plate 302 and the gear ring 3034 are fixed by the locking pin 2 3036, so that when the gear ring 3034 is subjected to the rotational force, the upper steel plate 302 rotates accordingly. In this assembly method, the assembly stability between the upper steel plate 302 and the supporting steel plate 301 can be effectively increased.

[0041] Specifically, two sliders 3021 are installed at the bottom of the upper steel plate 302, and the side of the sliders 3021 is arranged in a L-shaped manner. The top surface of the supporting steel plate 301 is provided with an arc groove 3012 that is consistent with the sliding track of the sliders 3021 when the upper steel plate 302 rotates. Two transverse grooves 3013 for guiding the lateral movement of the upper steel plate 302 are also provided on the top surface of the supporting steel plate 301, and the transverse grooves 3013 are connected to the arc grooves 3012. The coordinated application of the transverse grooves 3013, the arc grooves 3012 and the sliders 3021 can further increase the assembly stability of the upper steel plate 302 when it is superimposed on the supporting steel plate 301.

[0042] Embodiment 3

[0043] like Figure 1-Figure 3 As shown, in order to effectively adjust the overall size of the logistics handling automatic guided vehicle so as to facilitate its flexible use, a through groove 101 is opened between one side and the back side of the vertical plate 1, and the height of the through groove 101 matches the thickness of the platform mechanism 3, and an L-shaped folding plate 102 is slidably connected inside the through groove 101, and the vertical height of the L-shaped folding plate 102 is greater than the height of the through groove 101, and pulleys 103 are installed at the bottom of the L-shaped folding plate 102 and the bottom of the supporting steel plate 301, and one side of the supporting steel plate 301 in the two platform mechanisms 3 is fixedly connected to the side of the vertical plate 1 and the L-shaped folding plate 102, respectively, and the top surface of one platform mechanism 3 is at the same height as the bottom surface of the other platform mechanism 3. By applying external force to the platform mechanism 3 on the L-shaped folding plate 102, it can be prompted to slide horizontally along the bottom wall of the through groove 101, thereby changing the comprehensive length between itself and another platform mechanism 3, so as to achieve the purpose of conveniently adjusting the size of the entire guide cart, thereby facilitating the guide cart to flexibly adjust its own extension state according to whether it is in use and the number of express parcels being transported.

[0044] Embodiment 4

[0045] In the third embodiment, after the platform mechanism 3 that can slide relative to the vertical plate 1 is extended, the vibration force generated by the movement of the guiding trolley easily causes the platform mechanism 3 to slide horizontally, thereby affecting the safety of the express items placed on its top surface. In order to effectively ensure the stability of the platform mechanism 3 after it is extended. Figure 2 , Figure 3 and Figure 5As shown, a lifting assembly 4 for maintaining the two platform mechanisms 3 in an unfolded state is installed on the front side of the vertical plate 1, and the lifting assembly 4 includes an electric push rod 401 embedded in the vertical plate 1. The electric push rod 401 is also of a storage type, which is convenient for use without wires. A connecting plate 402 is installed on the free end of the electric push rod 401, and a baffle 1 403 is installed on the top of the connecting plate 402 when the two platform mechanisms 3 are in the unfolded state. The baffle 2 404 is installed on both sides of the top of the connecting plate 402, and the back side and the front side of the supporting steel plate 301 are in the same vertical plane. The baffle 2 404 is embedded with a sensor 405 electrically connected to the motor structure 3055. The vertical height of the L-shaped folding plate 102 is at least twice the thickness of the upper steel plate 302. In actual application, the electric push rod 401 is operated to extend downward or retract upward to drive the connecting plate 402, baffle 1 403 and baffle 2 404 to adjust their positions up and down accordingly. Under normal circumstances, the electric push rod 401 can remain in a downward extension state, so that a height difference is generated between the top of baffle 1 403 and the bottom of the L-shaped folding plate 102.

[0046] When two platform mechanisms 3 are needed, one platform mechanism 3 that can slide along the vertical plate 1 is extended to one side to the maximum value, and then the electric push rod 401 is controlled to shrink upward by a set value of one, thereby driving the baffle plate 1 403 and the baffle plate 2 404 to move upward through the connecting plate 402, so that the baffle plate 1 403 is attached to one side of the L-shaped folding plate 102, thereby limiting it, avoiding the platform mechanism 3 from moving horizontally without reason during the transportation of express items, thereby ensuring the safety of the express items during transportation;

[0047] In addition, when it is necessary to make the rotated upper steel plate 302 return to a state of perfect overlap with the supporting steel plate 301, the electric push rod 401 continues to operate when the remaining rotation angle of the upper steel plate 302 is less than 90°, and is controlled to retract upward to the set value two, thereby continuing to drive baffle one 403 and baffle two 404 to move upward through the connecting plate 402, so that the top of baffle two 404 is at the same height as the top surface of the upper steel plate 302 in the sliding platform mechanism 3, and the height of the sensor 405 is between the top surface height and the bottom surface height of the upper steel plate 302. When the motor structure 3055 is operated to control the upper steel plate 302 to return to its original position, the side of the upper steel plate 302 contacts the outer surface of the baffle 2 404, and the sensor 405 senses the existence of the upper steel plate 302 at this time, and can feed back a signal to the motor structure 3055 to make it stop running immediately. At the same time, the baffle 2 404 has a limiting effect on the upper steel plate 302 to prevent it from continuing to rotate due to inertia, thereby effectively ensuring that the upper steel plate 302 perfectly overlaps with the supporting steel plate 301 when it rotates back.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
