[0023] Please also read Figure 1 and Figure 5 , the logistics robot provided by the present invention is now described. The logistics robot includes a vehicle body 1, a cabinet body 2, a plurality of opening and closing components and a plurality of ejection units. The cabinet body 2 is fixedly mounted on the vehicle body 1, and the cabinet body 2 is provided with a plurality of storage slots 21, and the plurality of storage slots 21 are sequentially arranged along the vertical direction, and one end of the storage slots 21 along the first horizontal direction is an open end. The plurality of opening and closing components correspond to the plurality of storage slots 21 one by one, and the opening and closing components are located at the open ends of the corresponding storage slots 21 and are used to open and close the open ends of the corresponding storage slots 21. The plurality of ejection units correspond to the plurality of storage slots 21 one by one, and the ejection units include an ejection member 41 and a pushing shaft 42, and the ejection member 41 is slidably arranged in the corresponding storage slot 21 along the first horizontal direction, and the length direction of the pushing shaft 42 is arranged along the sliding direction of the ejection member 41, and the pushing shaft 42 is fixedly connected to the ejection member 41, and the pushing shaft 42 slides through the side wall of the cabinet body 2.

[0024] Compared with the prior art, the logistics robot provided by the present invention has a body 1 that drives the cabinet 2 to move. When the opening and closing assembly opens the opening end of the corresponding storage slot 21, the express in the storage slot 21 can be taken out. When the volume of the express is almost the same as the internal space of the storage slot 21, making it difficult for the person picking up the item to put his hand between the express and the side of the storage slot 21, the push shaft 42 is used to push the push member 41 to slide toward the opening end of the corresponding storage slot 21 until the express in the storage slot 21 is pushed out of the storage slot 21, and then the person picking up the item can take the express again, thereby avoiding the problem that it is difficult for the person picking up the item to take out the express from the storage slot 21.

[0025] In some embodiments, the above-mentioned characteristic opening and closing components can be used as follows Figures 1 to 3 See the structure shown. Figures 1 to 3The opening and closing assembly includes two fixed seats 31, a first rotating shaft 32, a second rotating shaft 33, an opening and closing plate 34, a driving motor 35 and two meshing driving gears 36. The two fixed seats 31 are respectively located on both sides of the storage slot 21 along the second horizontal direction, and the fixed seats 31 are fixedly connected to the cabinet 2, and the second horizontal direction is perpendicular to the first horizontal direction. The first rotating shaft 32 and the second rotating shaft 33 are coaxially arranged and the axis center line is arranged along the second horizontal direction, and the first rotating shaft 32 and the second rotating shaft 33 are respectively rotatably arranged in the two fixed seats 31. The opening and closing plate 34 is located between the two fixed seats 31 and is in contact with both fixed seats 31, and the opening and closing plate 34 is fixedly connected to the first rotating shaft 32 and the second rotating shaft 33. The driving motor 35 is fixed on the cabinet 2. Two meshing driving gears 36 are respectively sleeved and fixed on the output shaft and the second rotating shaft 33 of the driving motor 35. The rotation of the first rotating shaft 32 and the second rotating shaft 33 enables the opening plate 34 to open and close the opening end of the corresponding storage slot 21. When the opening plate 34 is in the take-out position of opening the opening end of the corresponding storage slot 21, the opening plate 34 is in a horizontal state and the upper surface of the opening plate 34 is flush with the bottom surface of the corresponding storage slot 21. The output shaft of the drive motor 35 drives the opening plate 34 to rotate with the first rotating shaft 32 and the second rotating shaft 33 through two meshing drive gears 36, so that the opening plate 34 can open and close the opening end of the corresponding storage slot 21. When the opening plate 34 rotates to the take-out position of opening the opening end of the corresponding storage slot 21, since the upper surface of the opening plate 34 in a horizontal state is flush with the bottom surface of the corresponding storage slot 21, the express items pushed out of the storage slot 21 will move to the opening plate 34 in the take-out position, so that it is convenient for the pick-up personnel to take them.

[0026] In some embodiments, see Figure 1 , Figure 2 , Figure 3 and Figure 5, the fixing seat 31 is located at the side of the opening end of the storage slot 21 facing the outside of the cabinet 2, and the top surface of the fixing seat 31 is provided with a positioning hole 311. The logistics robot also includes a limiting component, and the limiting component includes a plug-in column 51 and a limiting member 52. There are two plug-in columns 51, and the two plug-in columns 51 are arranged in parallel. The limiting member 52 is fixed on the two plug-in columns 51, and a notch 521 is provided on the side of the limiting member 52. Among them, the two plug-in columns 51 can be respectively inserted into the two positioning holes 311 in one of the opening and closing components, so that the notch 521 faces the opening end of the storage slot 21 corresponding to the opening and closing component. In this embodiment, when the opening and closing plate 34 is located at the removal station and the two plug-in columns 51 are respectively inserted into the two positioning holes 311 in the opening and closing component where the opening and closing plate 34 is located, the limiting member 52 is sleeved outside the vertical space where the opening and closing plate 34 is located through the notch 521. In this way, when the express is pushed out from the storage slot 21, the express enters the notch 521, thereby preventing the express from falling off the opening and closing plate 34. When the express reaches the opening and closing plate 34, the two plug-in posts 51 are withdrawn from the respective inserted positioning holes 311, and then the express can be removed from the opening and closing plate 34.

[0027] In some embodiments, see Figure 1 and Fig. 9 The logistics robot also includes two pick-up and placement tubes 6 and two magnets 7. The two pick-up and placement tubes 6 are vertically arranged and fixed on the cabinet 2. The two magnets 7 are respectively located in the two pick-up and placement tubes 6, and the magnets 7 are fixed on the cabinet 2. The two plug-in columns 51 can be respectively inserted into the two pick-up and placement tubes 6 so that the two plug-in columns 51 are respectively attracted to the two magnets 7. When the limit assembly is not needed, the two plug-in columns 51 are respectively inserted into the two pick-up and placement tubes 6 so that the two plug-in columns 51 are respectively attracted to the two magnets 7, thereby preventing the limit assembly from being lost.

[0028] In some embodiments, see Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7, the cabinet 2 is provided with a first long hole 22 connected to the storage slot 21 at each storage slot 21, and the length direction of the first long hole 22 is arranged along the sliding direction of the ejection member 41, and the ejection unit also includes a fixed tube 43, a sliding shaft 44 and a limit block 46. The axis of the fixed tube 43 is arranged along the second horizontal direction, one end of the fixed tube 43 is located in the corresponding storage slot 21, and the other end is slidably penetrated in the first long hole 22 connected to the corresponding storage slot 21, and the fixed tube 43 is fixedly connected to the ejection member 41. The sliding shaft 44 is coaxially arranged with the fixed tube 43 and slidably penetrated in the fixed tube 43. The positioning shaft 45 is parallel to the sliding shaft 44 and fixedly connected. The limit block 46 is located in the corresponding storage slot 21 and fixedly connected to the cabinet 2. Among them, when the ejection member 41 is in an idle position, the express can be placed in the corresponding storage slot 21, and the sliding of the sliding shaft 44 can make the positioning shaft 45 slide into or out of the limit block 46. When the ejector 41 is in an idle position and a parcel is placed in the corresponding receiving slot 21, the initial state of the positioning shaft 45 is to penetrate into the limit block 46, thereby limiting the sliding of the ejector 41 and preventing the ejector 41 from sliding toward the opening and closing plate 34 and squeezing the parcel due to the push shaft 42 being accidentally touched. When the positioning shaft 45 exits the limit block 46, the ejector 41 can be driven to slide.

[0029] In some embodiments, see Figure 6 and Figure 7 , the positioning shaft 45 is located on one side of the radial direction of the fixed tube 43, and the side wall of the fixed tube 43 is provided with a second long hole 431, and the length direction of the second long hole 431 is arranged along the length direction of the fixed tube 43, and the ejection unit also includes a fixing rod 47. The fixing rod 47 is slidably inserted into the second long hole 431, and the two ends of the fixing rod 47 are fixedly connected to the sliding shaft 44 and the positioning shaft 45 respectively. The positioning shaft 45 is fixedly connected to the sliding shaft 44 through the fixing rod 47. When the sliding shaft 44 slides, the fixing rod 47 slides in the second long hole 431 accordingly. When the positioning shaft 45 withdraws from the limiting block 46, the limiting of the fixing rod 47 by the second long hole 431 can limit the rotation of the positioning shaft 45 around the sliding shaft 44, so that when the ejection member 41 reaches the idle position again, the positioning shaft 45 can penetrate into the limiting block 46.

[0030] In some embodiments, the above-mentioned feature ejection unit can be used as follows Figure 7 See the structure shown. Figure 7 The ejection unit further includes a first fixing ring 48. The first fixing ring 48 is sleeved and fixed on the sliding shaft 44, and the first fixing ring 48 is slidably inserted into the fixing tube 43. The sliding shaft 44 is slidably inserted into the fixing tube 43 through the first fixing ring 48.

[0031] In some embodiments, see Figures 5 to 8, the limit block 46 is located on the side of the fixed rod 47 facing the first long hole 22, the first fixed ring 48 is located in the cabinet 2, and the ejection unit also includes a second fixed ring 49 and a compression spring 50. The second fixed ring 49 is slidably sleeved on the sliding shaft 44 and is fixed in the fixed tube 43, and the second fixed ring 49 is located on the side of the first fixed ring 48 facing away from the first long hole 22. The compression spring 50 is sleeved on the sliding shaft 44, and the two ends of the compression spring 50 are respectively abutted against the first fixed ring 48 and the second fixed ring 49. When the positioning shaft 45 needs to be withdrawn from the limit block 46, the sliding shaft 44 is driven to slide, so that the first fixed ring 48 presses the compression spring 50 in the direction of the second fixed ring 49 until the positioning shaft 45 withdraws from the limit block 46. When the ejection member 41 slides and resets to the idle position, the sliding shaft 44 is released, and the resilience of the compression spring 50 drives the sliding shaft 44 to slide, so that the positioning shaft 45 re-inserts into the limit block 46.

[0032] In some embodiments, the above-mentioned feature ejection unit can be used as follows Figure 5 See the structure shown. Figure 5 The push-up unit further includes a push-pull shaft 501. The push-pull shaft 501 is perpendicular to the driving shaft 42 and is fixedly connected to one end of the driving shaft 42 outside the cabinet 2. It is convenient to drive the driving shaft 42 to slide by the push-pull shaft 501.

[0033] In some embodiments, the above-mentioned feature ejection unit can be used as follows Figure 4 , Figure 5 , Figure 7 and Figure 8 See the structure shown. Figure 4 , Figure 5 , Figure 7 and Figure 8 The ejection unit also includes a fixing member 502. The fixing member 502 is located on the side of the first long hole 22 facing the outside of the cabinet 2. The fixing member 502 is fixedly connected to the push-pull shaft 501. The fixing member 502 is provided with a threaded hole, and the axis of the threaded hole is arranged along the length direction of the fixed tube 43. The screw rod 503 is threadedly connected in the threaded hole. The movement of the screw rod 503 along its length direction can make the screw rod 503 penetrate into the fixed tube 43 to realize the ejection of the sliding shaft 44. When the ejection member 41 is in an idle position, the screw rod 503 is driven to rotate so that the screw rod 503 threadedly connected to the fixing member 502 penetrates into the fixed tube 43, thereby realizing the ejection of the sliding shaft 44, and then the first fixing ring 48 squeezes the compression spring 50 in the direction of the second fixing ring 49. When the driving screw rod 503 is rotated so that the screw rod 503 withdraws from the fixed tube 43, the sliding shaft 44 can be loosened.

[0034] Furthermore, the ejection unit further includes a driving shaft 504 , which is perpendicular to and fixedly connected to the screw rod 503 , and it is convenient to drive the screw rod 503 to rotate via the driving shaft 504 .

[0035] Furthermore, the side wall of the screw rod 503 has a limiting portion 5031 protruding outward, and the limiting portion 5031 and the driving shaft 504 are respectively located on both sides of the fixing member 502, thereby preventing the screw rod 503 from being separated from the fixing member 502.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
