[0031] The present invention is further described below in conjunction with examples. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading this description, various equivalent modifications to this description by those skilled in the art fall within the scope defined by the claims attached to this application.

[0032] Please combine Figures 1 to 3As shown, the article delivery trolley of the present embodiment includes a carriage 1, which is provided with a shelf 2, a mobile stacking platform 3, a lifting platform 4, a cargo box temporary storage channel 5, a top conveyor belt 6 and a bottom conveyor belt 7. The shelf 2 includes a plurality of cargo cavities 201 with side openings arranged vertically and horizontally, and a movable cargo box 8 is provided in the cargo cavity 201. The mobile stacking platform 3 is arranged on the side of the shelf 2 for receiving or delivering the cargo box 8 from the opening of the cargo cavity 201. The lifting platform 4 and the cargo box temporary storage channel 5 are respectively arranged on the front and rear sides of the mobile stacking platform 3. The top conveyor belt 6 is located above the mobile stacking platform 3 and is transported to the lifting platform 4 by the cargo box temporary storage channel 5. The bottom conveyor belt 7 is located below the mobile stacking platform 3 and is transported to the cargo box temporary storage channel 5 by the lifting platform 4. A pickup door 101 is provided at a position corresponding to the lifting platform 4 on the carriage 1, and a delivery door 102 is provided at a position corresponding to the top of the cargo box temporary storage channel 5 on the carriage 1. The shelves 2 can be arranged in pairs on the left and right sides of the mobile stacking platform 3. Multiple groups of such structures can be arranged on a trolley to fully utilize the lateral space of the trolley, so that the trolley does not need to adopt a narrow body design.

[0033] For details, please combine Figure 4 and Figure 5 As shown, the cargo cavity 201 on the shelf 2 is arranged in a vertical and horizontal matrix for storing cargo boxes 8. The bottom of the cargo cavity 201 is partially recessed to accommodate the movable stacking platform body 301, and when the cargo box 8 is in the cargo cavity 201, a portion of the bottom surface is suspended, so that the stacking platform body 301 can drive the cargo box 8 to move out. The outer side wall of the fixed bottom box 803 of the cargo box 8 is provided with a guide ball 807, and the side wall of the cargo cavity 201 is also provided with a guide groove 202, which is used to cooperate with the guide ball 807 on the cargo box 8 to ensure that the cargo box 8 accurately enters the cargo cavity 201.

[0034] Vertical slide grooves 203 are provided on both sides of the entrance of the cargo cavity 201. A rotatable stopper shaft 204 is provided in the slide groove 203. A lifting stopper 205 is sleeved on the upper part of the stopper shaft 204. A spiral groove 204a is provided on the surface of the stopper shaft 204. The end of the sleeved lifting stopper 205 cooperates with the spiral groove 204a to move in the spiral groove 204a to form a cam groove lifting mechanism. At the same time, the end of the lifting stopper 205 is also located in the slide groove 203 and guided up and down by the slide groove 203. In this way, when the stopper shaft 204 rotates, the lifting stopper 205 will move up and down along the slide groove 203. When the lifting stopper 205 rises, it will not affect the entry and removal of the cargo box 8. After the cargo box 8 enters the cargo cavity 201, the lifting stopper 205 descends to block the cargo box 8 to prevent it from sliding out of the cargo cavity 201.

[0035] A toggle gear 206 is fixedly mounted at the lower part of the barrier rod shaft 204. When the toggle gear 206 is engaged, it can drive the barrier rod shaft 204 to rotate to realize the up and down movement of the lifting barrier rod 205. The toggle rack 310 arranged on the stacking platform body 301 is engaged with the toggle gear 206, and the specific structure of the mobile stacking platform 3 is shown in the structural description.

[0036] Please combine Figure 6 , Figure 7 As shown, the mobile stacking platform 3 includes a frame 302, a stacking platform body 301, and a first driving mechanism for driving the stacking platform body 301 to move vertically and horizontally. The frame 302 is connected to the stacking platform body 301. The first driving mechanism drives the frame 302 to move vertically and horizontally so that the stacking platform body 301 reaches the corresponding cargo cavity 201 position. The first driving mechanism includes a longitudinal (up and down direction) screw rod 303, a longitudinal bracket 304, a transverse (front and back direction) screw rod 305, a transverse bracket 306, a longitudinal slide rod 307, and a transverse slide rod 308. The frame 302 is longitudinally slidably matched with the longitudinal slide rod 307 and transversely slidably matched with the transverse slide rod 308. The transverse slide rod 308 is driven by the longitudinal screw rod 303 to move up and down along the longitudinal bracket 304, so that the frame 302 moves along the longitudinal slide rod 307. The longitudinal slide rod 307 is driven by the transverse screw rod 305 to move forward and backward along the transverse bracket 306, so that the frame 302 moves along the transverse slide rod 308.

[0037] The stacking platform body 301 is arranged on the frame 302, and the frame 302 is provided with a translation mechanism to drive the stacking platform body 301 to move left and right. Specifically, the translation mechanism includes a translation screw 309, and one side of the stacking platform body 301 and the translation screw 309 form a screw nut kinematic pair. In addition, a toggle rack 310 is also processed on the side of the stacking platform body 301. When the translation mechanism drives the stacking platform body 301 to translate, the toggle rack 310 meshes with the toggle gear 206, thereby driving the stop lever shaft 204 to rotate.

[0038] The stacking platform body 301 is provided with a second driving mechanism 311 for driving the cargo box 8 to move left and right and a third driving mechanism 312 for driving the cargo box 8 to move forward and backward. The second driving mechanism 311 and the third driving mechanism 312 have the same structure, both of which are lifting gear mechanisms. The lifting gear mechanism includes a lifting bracket 901. The lifting bracket 901 is provided with a driving motor 902 and a driving gear 903. The driving gear 903 is driven to rotate by the driving motor 902. The rotation axes of the driving gear 903 of the second driving mechanism 311 and the third driving mechanism 312 are perpendicular to each other. Fig.13As shown, the bottom surface of the cargo box 8 is provided with a left-right rack 801 and a front-back rack 802, wherein the left-right rack 801 is used to mesh with the driving gear 903 of the second driving mechanism 311, and the front-back rack 802 is used to mesh with the driving gear 903 of the third driving mechanism 312. When it is not necessary to drive the cargo box 8 to move, the lifting bracket 901 descends so that the driving gear 903 is lower than the top surface of the stacking platform body 301, and when it is necessary to drive the cargo box 8 to move, the lifting bracket 901 rises so that the driving gear 903 is higher than the top surface of the stacking platform body 301.

[0039] Please combine Figure 8 As shown, the lifting platform 4 includes a lifting platform body 401 and a fourth driving mechanism for driving the lifting platform body 401 to move up and down. The fourth driving mechanism includes a lifting screw 402 and a lifting guide rod 403 in the vertical direction. The lifting platform body 401 and the lifting screw 402 constitute a screw nut kinematic pair, and move up and down under the guidance of the lifting guide rod 403. The lifting platform body 401 is provided with a fifth driving mechanism 404 for driving the cargo box 8 to move forward and backward. The fifth driving mechanism 404 is also a lifting gear mechanism, and its working method is not repeated.

[0040] Please combine Fig. 9 and Fig.10 As shown, the cargo box temporary storage channel 5 is a channel for stacking cargo boxes 8 in a longitudinal direction. A lifting assembly 501 is provided at the bottom of the cargo box temporary storage channel 5, and a guide slide 502 is provided at the front side of the lifting assembly 501 for transition between the bottom conveyor belt 7 and the lifting assembly 501. Two groups of flip baffles 503 are provided at the lower and upper parts of the cargo box temporary storage channel 5, respectively. The lower flip baffle 503 is located above the lifting assembly 501, and the upper flip baffle 503 is located above the delivery door 102. The flip baffle 503 is set to be able to flip upward but not flip downward, that is, the flip baffle 503 is flipped down to the extreme position perpendicular to the side wall of the cargo box temporary storage channel 5 in a normal state. When the cargo box 8 moves up in the cargo box temporary storage channel 5, the flip baffle 503 can be pushed to flip up so that the cargo box 8 can pass through. After the cargo box 8 passes over the flip baffle 503, the flip baffle 503 flips down to the extreme position due to gravity. At this time, the flip baffle 503 can prevent the cargo box 8 from falling.

[0041] A swingable push plate 504 is provided at the rear side of the top of the cargo box temporary storage passage 5, and the push plate 504 is located above the upper flip baffle 503. When the topmost cargo box 8 is supported by the upper flip baffle 503, the push plate 504 swings to push the cargo box 8 toward the top conveyor belt 6.

[0042] The working process of the above embodiment is as follows: when it is necessary to pick up items, the first driving mechanism moves the stacking platform body 301 to the cargo cavity 201 where the cargo box 8 where the items are stored is located, and the stacking platform body 301 is driven by the translation mechanism to move toward the cargo cavity 201. During the movement, the toggle rack 310 is meshed with the toggle gear 206, and the lever shaft 204 rotates to raise the lifting lever 205. After part of the stacking platform body 301 moves to the bottom of the cargo box 8, the driving gear 903 of the second driving mechanism 311 rises and meshes with the left and right racks 801 on the bottom surface of the cargo box 8, and then the driving gear 903 rotates to move the cargo box 8 out of the cargo cavity 201 to the stacking platform body 301, and the driving gear 903 of the second driving mechanism 311 is lowered and reset. Subsequently, the stacking platform body 301 returns to the middle of the frame 302 under the drive of the translation mechanism, and at this time, the toggle gear 206 is reversely toggled, and the lifting lever 205 moves downward. The first driving mechanism then drives the stacking platform body 301 to the position of the lifting platform 4. The driving gear 903 of the third driving mechanism 312 rises and meshes with the front-to-back rack 802 on the bottom surface of the cargo box 8, and then the driving gear 903 rotates to move the cargo box 8 from the stacking platform body 301 to the lifting platform body 401. During this period, the driving gear 903 of the fifth driving mechanism 404 on the lifting platform body 401 also rises and meshes with the front-to-back rack 802 on the bottom surface of the cargo box 8. After the cargo box 8 is transferred to the lifting platform body 401, the driving gear 903 of the third driving mechanism 312 is lowered and reset. The person who picks up the items can open the pickup door 101 to pick up the items from the cargo box 8.

[0043] After the collection is completed, the collection door 101 is closed, and the lifting platform body 401 moves down to the position of the bottom conveyor belt 7 under the drive of the fourth driving mechanism. The driving gear 903 of the fifth driving mechanism 404 rises and meshes with the front-to-back rack 802 on the bottom surface of the cargo box 8, and then the driving gear 903 rotates to move the cargo box 8 from the lifting platform body 401 to the bottom conveyor belt 7, and then the fifth driving mechanism 404 is reset. The bottom conveyor belt 7 transports the empty cargo box 8 to the bottom of the cargo box temporary storage channel 5, and the cargo box 8 moves to the lifting assembly 501 through the guide slide 502. The lifting assembly 501 rises and sends the cargo box 8 into the cargo box temporary storage channel 5, and is blocked from falling by the lower flip baffle 503. Multiple cargo boxes 8 are stacked up and down in the cargo box temporary storage channel 5 in sequence.

[0044] When the delivery person puts the items to be delivered into the cart, he opens the delivery door 102 and puts the items into the empty cargo box 8. Then the lifting assembly 501 rises to push up the cargo box 8 with the items placed in it. The cargo box 8 is blocked by the upper flip baffle 503. At the same time, the corresponding position of the delivery door 102 is the next empty cargo box 8, and the delivery person can continue to put items in it. The topmost cargo box 8 moves toward the top conveyor belt 6 under the push of the push plate 504, and the lifting platform body 401 is driven to the end of the top conveyor belt 6. The top conveyor belt 6 delivers the cargo box 8 to the lifting platform body 401, and then transfers it to the stacking platform body 301, and the stacking platform body 301 delivers the cargo box 8 to the corresponding empty cargo cavity 201. When the stacking platform body 301 with the cargo box 8 moves toward the cargo cavity 201, the toggle rack 310 will also be engaged with the toggle gear 206, thereby causing the lifting and lowering stop rod 205 to rise. After the cargo box 8 is delivered into the cargo cavity 201 and moves out of the stacking platform body 301, the lifting and lowering stop rod 205 descends to block the side of the cargo box 8 to prevent it from sliding out.

[0045] In some preferred embodiments, in order to facilitate the taking and placing of items and increase the number of cargo boxes 8 that can be accommodated in the cargo box temporary storage channel 5, please combine Fig.11 , Fig.12As shown, the shelf 2 is designed as a compressible structure. Specifically, the cargo box 8 includes a fixed bottom box 803 and a telescopic upper box 804. The telescopic upper box 804 includes telescopic pillars 805 located at the four corners of the cargo box 8 and a flexible enclosure 806 arranged between the telescopic pillars 805. The telescopic pillars 805 include at least two sets of telescopic joints 8051. The ends of the telescopic joints 8051 that cooperate with each other are provided with pin holes and telescopic pins 8052. The telescopic pins 8052 are provided with inclined guide grooves 8052a. The ends of the telescopic joints 8051 have guide pins 8051a arranged in the guide grooves 8052a. When the telescopic joints 8051 are pressed down, the guide pins 8051a generate oblique forces on the telescopic pins 8052 through the guide grooves 8052a to retract the telescopic pins 8052. When the telescopic joints 8051 are lifted up, when the telescopic pins 8052 are driven to the pin hole position, the springs on the back side automatically extend the pins and lock them. It should be noted that the above structure only describes a specific structure of the telescopic support 805, and other prior art structures can also be used in the present invention. In order to facilitate the lifting of the telescopic support 805, a crossbar 808 is connected in the middle of the top of the two telescopic supports 805. A pressing mechanism 405 for pressing down the telescopic support 805 to shorten the telescopic support 805 is set on the side of the lifting platform body 401 of the lifting platform 4. The pressing mechanism 405 can be implemented by a screw nut motion mechanism. Similarly, the top of the cargo box temporary storage channel 5 is also provided with a support plate 505 for pushing up the telescopic support 805 above the upper flip baffle 503. The support plate 505 can be set as a horizontally rotatable structure. After the cargo box 8 is supported by the upper flip baffle 503, the support plate 505 rotates to the bottom of the crossbar 808, and then the telescopic upper box 804 of the cargo box 8 is unfolded upward by moving the support plate 505 upward (which can be driven to move upward by the screw nut motion mechanism).
