Description

Technical Field

[0001] The present invention relates to the technical field of motorized vehicles, and particularly relates to a closed-type freight express vehicle. Background Art

[0002] A closed-type freight express vehicle is an enclosed van specially designed for urban logistics and express delivery, featuring high safety, large cargo space, strong adaptability, etc., and is widely used in fields such as express end delivery, e-commerce logistics, etc.;

[0003] With the rapid development of e-commerce and the continuous upgrading of the logistics industry, closed-type freight express vehicles are gradually updated to unmanned ones; as an intelligent distribution tool, unmanned express vehicles are gradually becoming an important means to solve the "last mile" distribution problem. Through autonomous driving technology and intelligent dispatching systems, unmanned express vehicles can achieve efficient and accurate express delivery, effectively reducing labor costs and improving distribution efficiency. However, in actual applications, there are still some technical defects in the cargo box design of existing unmanned express vehicles, which limit their further promotion and application.

[0004] The cargo box capacity of existing unmanned express vehicles is fixed. After the express deliveries in the cargo box are completed, the express vehicle needs to return to the express station empty to replenish goods, and then set off again to the next delivery address. This replenishment method results in a large number of ineffective driving miles during the distribution process of the express vehicle, not only increasing energy consumption, but also prolonging the overall distribution cycle and reducing distribution efficiency. Especially in areas with intensive distribution tasks, frequent round trips for replenishment will further exacerbate this problem. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a closed-type freight express vehicle, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0007] A closed-type freight express vehicle, comprising a vehicle body;

The side sealing and blocking components stop and position the UAV main body from the inside of the outer box, and the flexible sealing and blocking components close the openings of the inner row of vertically arranged box bodies.

[0014] When the storage bin is nearly empty, the UAV replenishment component returns to the express station to load goods. The two groups of side sealing and blocking components are docked, and the two groups of flexible sealing and blocking components are docked to jointly form a suspension box. After the UAV replenishment component is fully loaded, it returns to the storage bin and waits for personnel to replenish goods.

[0015] Furthermore, a touch panel is provided on the outer wall of the box door, and multiple material boxes are provided at the bottom of the box door. The number of material boxes is the same as the number of vertically arranged box bodies in the same row. A group of electric sealing plates is provided on the outside of each group of material boxes.

[0016] Furthermore, a slidable electric anti-theft plate is installed on the top surface of the outer box, and the electric anti-theft plate is used to close the docking window.

[0017] Furthermore, the side sealing and blocking component includes a side vertical plate. The bottom end of the side vertical plate is rotatably connected to a surrounding main board, and a first motor is installed at the rotation connection. The surrounding main board is symmetrically connected with surrounding sub-boards inside.

When the two groups of flexible sealing and blocking components are docked, the two groups of assembly strips are fixed through a clamping component, and the blocking curtain conducts bottom enclosure.

[0019] Furthermore, the engaging member includes a first clamping block and a second clamping block. The middle part of a group of assembly strip blocks is embedded in the first clamping block. In the middle of the side wall of the first clamping block, there is a hook with its hooked part facing downwards. The bottom surface of the other group of assembly strip blocks is embedded in the second clamping block. Inside the second clamping block, there are a first groove and a second groove. The second groove is located at the outer end of the first groove. Inside the second groove, a sliding rod is horizontally and slidably installed. The inner end of the sliding rod is connected to a key block, and the outer end is connected to a pulling frame. The pulling frame is arranged at the outer end of the second clamping block. A return spring is sleeved outside the sliding rod. The outer end of the return spring is connected to the inner wall of the second groove, and the inner end is connected to the key block. The return spring is used to drive the key block to extend into the first groove. When the hook is clamped into the first groove from bottom to top, the key block stops at the bottom of the hook.

[0020] Furthermore, the annular conveying component includes a lower base and an upper base. A longitudinal chute is opened on the inner bottom surface of the outer box body. On the inner end side wall of the lower base, there is a slider which is embedded in the longitudinal chute. A screw rod passes through the slider internally in a threaded manner. One end of the screw rod is connected to a third motor, and both ends of the screw rod are installed on the inner bottom surface of the outer box body. The middle part of the lower base is connected to the upper base through multiple central rods. A lower annular belt is installed on the surface of the lower base, and an upper annular belt is arranged on the bottom surface of the upper base.

[0021] Furthermore, inside the vertical box body, multiple independent chambers are opened from top to bottom. The outer side of the chamber is an open structure. On the back of the vertical box body, there is a back rod. The top end of the back rod is connected to the upper annular belt, and the bottom end is connected to the lower annular belt.

[0022] Furthermore, on the inner side of each group of annular conveying components, restraint guide rails are symmetrically arranged. The bottom end of the restraint guide rail is fixedly arranged on the inner bottom surface of the outer box body, and the top end is an open end. An electromagnetic strip is embedded in the inner wall of the restraint guide rail. Metal blocks are arranged at both ends of the assembly strip block. When delivering goods to the storage bin, the blocking curtain is lowered to enclose and block the inner row of vertical box bodies, and both ends of the assembly strip block are vertically inserted into the restraint guide rails.

[0023] Furthermore, the material grabbing assembly includes a horizontal guide rail which is arranged on one side inside the outer box body. On the top of the horizontal guide rail, a vertical guide rail is vertically and slidably installed. Inside the inner wall of the vertical guide rail, a longitudinal guide rail is vertically slidably installed. The bottom of the longitudinal guide rail is slidably installed with an upper plate body. The bottom of the upper plate body is rotatably connected to a lower plate body. On the side of the lower plate body, there is a second driving rod. At the output end of the second driving rod, there is an opening and closing guide rail.

[0024] The present invention provides a closed - type cargo - carrying express delivery vehicle. Compared with the prior art, it has the following beneficial effects:

[0025] 1. When no material replenishment is required, the UAV body stays on the outer box body. In this way, the UAV body can move together with the unmanned delivery vehicle. The side sealing and blocking component and the flexible sealing and blocking component can be switched to the staying mode. At this time, the side sealing and blocking component can stop and position the UAV body from the inside to prevent the UAV body from falling off, and the flexible sealing and blocking component can be unfolded to surround the inner row of vertical box bodies to prevent the express delivery from slipping out.

[0026] 2. When the express delivery in the storage component is about to be delivered, the side sealing and blocking component and the flexible sealing and blocking component are switched to the flying material fetching mode. The side sealing and blocking component rotates to the vertical state, and the flexible sealing and blocking component is retracted. When arriving at the express delivery station, the worker docks the two groups of flexible sealing and blocking components, and the two groups of side sealing and blocking components and the two groups of flexible sealing and blocking components are docked together to jointly form a lifting container. The worker at the express delivery station can then put the express delivery into the lifting container. At the same time, after the unmanned delivery vehicle has completed the delivery, it will drive to the best waiting point without having to return to the express delivery station, thus saving power and time.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In order to solve the technical problems in the background technology, a closed cargo-carrying express delivery vehicle is provided as follows:

[0043] Combination Figures 1 - 12As shown in the figure, a closed cargo-type express vehicle provided by the present invention includes a vehicle body 9a, and an outer box body 1 which is arranged on the top surface of the vehicle body 9a. A docking window is opened in the middle of the top surface of the outer box body 1; one side surface thereof is an open structure, and a box door 2 is hinged at the opening;

[0044] A material grabbing assembly 3 is arranged in the middle of the inner part of the outer box body 1;

[0045] A storage assembly 4 is symmetrically arranged at both ends of the material grabbing assembly 3. It includes an annular conveying component which is longitudinally slidably installed in the outer box body 1. A plurality of vertically arranged box bodies 45 distributed in a ring are connected to the side part of the annular conveying component. The side surface of the vertically arranged box body 45 is an open structure; the plurality of vertically arranged box bodies 45 connected by the annular conveying component are always arranged in two rows, inner and outer. The openings of the inner row of vertically arranged box bodies 45 all face the material grabbing assembly 3 to wait for the material grabbing assembly 3 to grab materials. The openings of the outer row of vertically arranged box bodies 45 are all attached to the inner wall of the outer box body 1, and the outer box body 1 closes the outer row of vertically arranged box bodies 45;

[0046] An unmanned aerial vehicle (UAV) replenishment assembly 5 includes a UAV main body 51. A cover plate 52 is connected to the bottom of the UAV main body 51. The cover plate 52 covers the docking window. Side sealing and blocking components are symmetrically installed on the bottom surface of the cover plate 52. A flexible sealing and blocking component 6 is rotatably connected to the bottom of each group of side sealing and blocking components;

[0047] When replenishing the storage bin, the box door 2 is opened, and the storage assembly 4 is communicated with the space outside the outer box body 1. The replenisher places the express deliveries into each vertically arranged box body 45;

[0048] When delivering goods from the storage bin, the UAV main body 51 stays at the docking window. The side sealing and blocking components stop and position the UAV main body 51 from the inside of the outer box body 1, and the flexible sealing and blocking component 6 closes the openings of the inner row of vertically arranged box bodies 45;

[0049] When the storage bin is nearly empty, the UAV replenishment assembly 5 returns to the express station to load goods. The two groups of side sealing and blocking components are docked, and the two groups of flexible sealing and blocking components 6 are docked to jointly form a lifting and packing box; after the UAV replenishment assembly 5 is filled, it returns to the storage bin and waits for personnel to replenish goods.

[0050] In the above solution:

[0051] 1. The design of the storage assembly 4 can achieve the following effects:

[0052] 1.1. The simplest multiple vertically arranged box bodies 45 are used for storing goods. No cabinet doors are arranged on the outside of the vertically arranged box bodies 45, and they are of an open structure, effectively reducing the design cost of the storage cabinet and reducing the mechanical failure rate;

[0053] 1.2. Divide the vertical box body 45 into two rows. The openings of the outer row always face outwards, so that the inner wall of the outer box body 1 can be used for blocking, eliminating the need for a separately designed blocking structure. The inner row of vertical box bodies 45 faces the material grabbing assembly 3 and is the row waiting for material grabbing. It is blocked by the flexible blocking component 6 of the UAV replenishment component 5, and a separate blocking structure is also required.

[0054] 1.3. Use a circular conveying component to switch between groups of two rows of vertical box bodies 45 to achieve automatic side switching. The switching is simple and the space utilization rate is high.

[0055] 2. The design of the UAV replenishment component 5 can achieve the following effects:

[0056] 2.1. When no replenishment is needed, the UAV main body 51 stays on the outer box body 1. In this way, the UAV main body 51 can move with the unmanned delivery vehicle. The side blocking component and the flexible blocking component 6 can be switched to the staying mode. At this time, the side blocking component can stop and position the UAV main body 51 from the inside to prevent the UAV main body 51 from falling off, and the flexible blocking component 6 can be unfolded to surround the inner row of vertical box bodies 45 to prevent the express delivery from slipping out.

[0057] 2.2. When the express delivery in the storage component 4 is about to be delivered completely, the side blocking component and the flexible blocking component 6 are switched to the flying material grabbing mode. The side blocking component rotates to the vertical state, and the flexible blocking component 6 is retracted. When arriving at the express delivery station, the worker docks the two groups of flexible blocking components 6, and the two groups of side blocking components and the two groups of flexible blocking components 6 are docked together to form a lifting container. The worker at the express delivery station can then put the express delivery into the lifting container. At the same time, after the unmanned delivery vehicle has completed the delivery, it will drive to the best waiting point without having to return to the express delivery station, thus saving power and time.

[0058] After the lifting container is full, the UAV main body 51 returns to the best waiting point and sends a replenishment message to the nearest courier. The UAV main body 51 returns and lands on the docking window. The nearest courier arrives beside the storage bin and performs a manual replenishment operation.

[0059] 3. The cargo box of the existing unmanned delivery vehicle usually adopts a design of divided storage cavities, and an automatically opening and closing cabinet door is set outside each storage cavity. Although this design improves the user experience, it also brings significant technical problems. First of all, each cabinet door needs to be equipped with an independent driving device and control system to control the opening and closing of the cabinet door, resulting in a complex structure of the cargo box and a significant increase in manufacturing cost. To solve the above problems, an open storage component 4 and an internal picking material grabbing component 3 are designed. The blocking and picking operations are both relatively simple. When the box body is relatively large, the picking operation can also be normally completed, and more express deliveries can be carried.

[0060] In this embodiment, a touch panel 21 is provided on the outer wall of the box door 2, and a plurality of material boxes 22 are provided at the bottom of the box door 2. The number of the material boxes 22 is the same as the number of the vertical box bodies 45 in the same row. A set of electric sealing plates 23 are provided on the outer side of each group of the material boxes 22; a slidable electric anti-theft plate 8 is installed on the top surface of the outer box body 1.

[0061] In the above solution: during delivery, the material grabbing assembly 3 grabs each row of express deliveries in a row of vertical box bodies 45 each time. For example, if the number of the inner row of vertical box bodies 45 is four, then the number of the material boxes 22 is also four. The courier puts them in row by row from bottom to top according to the delivery order. The material grabbing assembly 3 grabs the express deliveries in the vertical box bodies 45 from bottom to top. In this way, it can be ensured that the outside of the unremoved express deliveries is always sealed by the blocking curtain 64. At the same time, the programming of the entire material grabbing program in the background is also simpler;

[0062] The material grabbing assembly 3 first grabs four express deliveries in the bottom row, and then transfers them into the material box 22. The user picks up the goods through the touch panel 21, and then the electric sealing plate 23 corresponding to the material box 22 is opened, and the user can take away the express delivery from the material box 22;

[0063] When the drone main body 51 flies away to replenish goods, the electric anti-theft plate 8 moves to the docking window to seal the docking window.

[0064] In this embodiment, the side blocking member includes a side vertical plate 53. The bottom end of the side vertical plate 53 is rotatably connected to the enclosing main board 54, and a first motor 531 is installed at the rotation connection. The inner side of the enclosing main board 54 is symmetrically connected with enclosing sub-boards 55. During the delivery of the storage bin, the side vertical plate 53 is inserted into the docking window. The enclosing main board 54 and the side vertical plate 53 are arranged at a right angle, and the enclosing main board 54 stops at the inner top surface of the outer box body 1.

[0065] In the above solution: when the drone main body 51 is placed on the outer box body 1, the side vertical plate 53 can be inserted into the docking window, and the first motor 531 drives the enclosing main board 54 to rotate 90°, so that the enclosing main board 54 is parallel and attached to the inner bottom surface of the outer box body 1; in this way, the cover plate, the vertical plate and the enclosing main board form an I-shaped clamping and blocking structure, so that the drone is stably placed at the docking window;

[0066] When the drone main body 51 replenishes materials, the first motor 531 drives the enclosing main board 54 to flip to the vertical state, so that the two enclosing sub-boards 55 are butted against each other to form a rectangular enclosing structure.

[0067] In this embodiment, the flexible baffle member 6 includes a side box body 61. The side box body 61 is arranged at the bottom end of the baffle main board 55. A winding wheel 62 is rotatably installed inside the side box body 61. A second motor 63 for driving the winding wheel 62 to rotate is arranged at the end of the side box body 61. A blocking curtain 64 is wound on the outer wall of the winding wheel 62. An assembly strip block 65 is arranged at the end of the blocking curtain 64. When two groups of flexible baffle members 6 are butted, the two assembly strip blocks 65 are fixed by a clamping member 7, and the blocking curtain 64 is used for bottom baffle.

[0068] In the above solution:

[0069] In the stage of the transportation and storage bin, the blocking curtain 64 is lowered and blocked inside the inner row of vertical boxes to prevent the express delivery from falling.

[0070] When replenishing materials are needed, the blocking curtain 64 can be wound on the winding wheel 62 and then stored in the side box body 61. The two baffle main boards rotate inward and butt, so that the side baffle member and the flexible baffle member can be separated from the docking window. After flying to the express delivery station, the second motor 63 drives the winding wheel 62 to rotate, so that the blocking curtain 64 is released. Workers can butt the clamping members 7 of the two assembly strip blocks 65, and the two blocking curtains can form a bottom baffle structure.

[0071] In this embodiment, the clamping member 7 includes a first clamping block 71 and a second clamping block 72. The middle part of a group of assembly strip blocks 65 is embedded with the first clamping block 71. A hanging hook 711 is arranged in the middle of the side wall of the first clamping block 71, and the hooked part of the hanging hook 711 faces downward. The bottom surface of the other group of assembly strip blocks 65 is embedded with the second clamping block 72. A first groove 721 and a second groove 722 are formed inside the second clamping block 72. The second groove 722 is located at the outer end of the first groove 721. A sliding rod 75 is horizontally and slidably installed inside the second groove 722. The inner end of the sliding rod 75 is connected to a key block 73, and the outer end is connected to a pulling frame 76. The pulling frame 76 is arranged at the outer end of the second clamping block 72. A return spring 74 is sleeved outside the sliding rod 75. The outer end of the return spring 74 is connected to the inner wall of the second groove 722, and the inner end is connected to the key block 73. The return spring 74 is used to drive the key block 73 to extend into the first groove 721. When the hanging hook 711 is clamped into the first groove 721 from bottom to top, the key block 73 is blocked inside the hanging hook 711.

[0072] In the above solution: When docking, workers insert the hanging hook 711 of the first clamping block 71 into the first groove 721 from bottom to top. During the insertion process, the arc surface of the key block 73 is touched and squeezed, so that the key block 73 withdraws and compresses the return spring 74. When the hanging hook 711 passes over the key block 73, the return spring 74 drives the key block 73 to extend below the hanging hook 711, and the key block 73 can block and position the hanging hook 711, realizing the connection of the two assembly strip blocks 65.

[0073] When the courier replenishes materials, he pulls the pulling frame 76, so that the key block 73 disengages from the hanging hook 711, and the two assembly bar blocks 65 can be automatically separated, and the express delivery falls in the middle of the inner cavity of the outer box body 1, and the courier can stack them in sequence.

[0074] In this embodiment, the structures such as the enclosure main board, the cover board, the side vertical board, the enclosure sub-board, and the assembly bar block that are connected to the UAV body are all made of lightweight materials to reduce the power consumption during the transfer of the UAV body.

[0075] In this embodiment, the annular conveying component includes a lower base 41 and an upper base 44. A longitudinal chute is opened on the inner bottom surface of the outer box body 1. A slider 412 is provided on the inner end side wall of the lower base 41. The slider 412 is embedded in the longitudinal chute. A screw rod 42 passes through the interior of the slider 412 in a threaded manner. One end of the screw rod 42 is connected to a third motor 421, and both ends of the screw rod 42 are installed on the inner bottom surface of the outer box body 1; the middle part of the lower base 41 is connected to the upper base 44 through a plurality of central rods 43. A lower ring belt 411 is installed on the surface of the lower base 41, and an upper ring belt 441 is provided on the bottom surface of the upper base 44; a plurality of independent chambers are opened in the vertical box body 45 from top to bottom. The outer side of the chamber is an open structure. A back rod 451 is provided on the back surface of the vertical box body 45. The top end of the back rod 451 is connected to the upper ring belt 441, and the bottom end is connected to the lower ring belt 411.

[0076] In the above solution: when switching the vertical box body 45, the inner ring belt and the outer ring belt rotate synchronously, so as to switch the inner and outer rows of the vertical box body 45; when replenishment is required, the courier rotates the box door 2 upward to open it. The opening method can be unlocked by a key or a touch panel 21. The screw rod 42 drives the slider 412 to move, and then drives the lower base 41 to move outwards, so that the entire annular conveying component and each vertical box body 45 all extend out of the outer box body 1, so that the courier can quickly place the express delivery in the chambers of each vertical box body 45. An independent motor for driving the upper ring belt to rotate independently is provided inside the upper base, and an independent motor for driving the lower ring belt to rotate independently is provided inside the lower base.

[0077] In this embodiment, constraint guide rails 9 are symmetrically provided on the inner side of each group of annular conveying components. The bottom ends of the constraint guide rails 9 are fixedly arranged on the inner bottom surface of the outer box body 1, and the top ends are open; electromagnetic strips 91 are embedded in the inner walls of the constraint guide rails. Metal blocks 651 are provided at both ends of the assembly bar block 65; when delivering goods to the storage bin, the blocking curtain 64 is lowered to enclose the inner row of vertical box bodies 45, and both ends of the assembly bar block 65 are vertically inserted into the constraint guide rails 9.

[0078] In the above solution: The enclosure main board is horizontally stopped on the inner top surface of the outer box body, and the side box body is located directly above the two restraint guide rails; When the blocking curtain 64 is in the enclosure vertical box body 45, the blocking curtain 64 descends, and the metal blocks 651 at both ends of the assembly strip 65 fall into the restraint guide rail 9, and then fall to the bottom along the restraint guide rail 9. Subsequently, the electromagnetic strip 91 is energized to adsorb the metal block 651, so that the blocking curtain 64 is stably placed outside the vertical box body 45; Exemplarily, the metal block is an iron block.

[0079] When the material grabbing assembly 3 picks up goods from bottom to top in sequence, the blocking curtain 64 is lifted by a section each time to expose the four chambers in one row of the express delivery, while maintaining the enclosure of the upper chambers.

[0080] In this embodiment, the material grabbing assembly 3 includes a horizontal guide rail 31, which is arranged on one side inside the outer box body 1. A vertical guide rail 32 is vertically slidably installed on the top of the horizontal guide rail 31. A longitudinal guide rail 33 is vertically slidably installed on the inner wall of the vertical guide rail 32. The bottom of the longitudinal guide rail 33 is slidably installed with an upper plate body 34. The bottom of the upper plate body 34 is rotatably connected to a lower plate body 35. A second driving rod 36 is provided on the side of the lower plate body 35. The output end of the second driving rod 36 is provided with an opening and closing guide rail 37. Claw jaws 371 are symmetrically slidably installed on the inner wall of the opening and closing guide rail 37.

[0081] In the above solution: When grabbing materials, the horizontal guide rail 31 and the vertical guide rail 32 cooperate for primary adjustment to make the claw jaws 371 approach the corresponding chambers. Then the second driving rod 36 drives the claw jaws 371 to extend into the chambers. Finally, the opening and closing guide rail 37 drives the two groups of claw jaws 371 to approach and clamp the express delivery; The lower plate body 35 can rotate self - sufficiently, so that the claw jaws 371 make a switch to take out the express delivery in the two vertical box bodies 45 on both sides.

[0082] When the present invention is specifically implemented:

[0083] When the unmanned delivery vehicle delivers goods, the unmanned aerial vehicle replenishment assembly is placed on the docking window, and the blocking curtain blocks the inner row of vertical box bodies; When the blocking curtain is lifted row by row from bottom to top, the material grabbing assembly grabs four express deliveries in one row each time, and then transfers them to four material boxes respectively; After the user receives the pick - up notice, the specified electric sealing plate is controlled to open through the touch panel, and then the express delivery can be taken out;

[0084] When replenishment is required, the unmanned aerial vehicle replenishment assembly folds up and then flies to the express delivery station for replenishment. The electric anti - theft plate translates to block the docking window, and the unmanned delivery vehicle continues to transport the express delivery along the predetermined path;

[0085] After all the express deliveries have been picked up, the delivery vehicle drives to the nearest replenishment point. The unmanned aerial vehicle replenishment assembly returns after being filled with materials. When the unmanned aerial vehicle replenishment assembly is about to reach the storage bin, the background will send a replenishment notice to the nearest courier, and the nearest courier will arrive at the delivery vehicle;

[0086] The courier unlocks and opens the box door through the touch panel, then manually separates the engaging parts so that the express delivery falls into the storage bin. The two groups of storage components move out synchronously, and the courier replenishes the goods into each vertical box from bottom to top according to the delivery order;

[0087] After the replenishment is completed, the courier leaves to continue with their original work, and the storage bin proceeds to the next stage of delivery.
