Description

Technical Field

[0001] This invention belongs to the field of unmanned vehicle technology, and relates to a smart unmanned vehicle for package pickup and its application in unmanned tobacco delivery services. Background Technology

[0002] With the development of technology, the application of unmanned vehicles is becoming more and more diversified, such as unmanned taxis and unmanned delivery vehicles, which greatly save labor costs and also significantly reduce the accident rate. Moreover, since unmanned vehicles can work continuously when there is electricity, they also greatly improve transportation efficiency. For example, unmanned vehicles can also be used for tobacco delivery.

[0003] Currently, when tobacco centers deliver cartons of cigarettes to different markets and / or merchants, the unmanned vehicles they use typically carry multiple small compartments, each with its own door and lock. Each lock can only be opened by the corresponding merchant, using methods such as mechanical keys or passwords. This effectively protects the privacy of merchants during cigarette transport and prevents unauthorized access. However, since the volume and capacity of each compartment are fixed, if each compartment contains a small quantity of cigarettes, the number of cigarettes delivered to each merchant at once will be limited; conversely, if a merchant has a large quantity of cigarettes, their corresponding compartment may not be full, resulting in poor efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a smart unmanned pickup vehicle and its application in unmanned tobacco delivery services, aiming to solve the problem of poor performance.

[0005] To solve the above-mentioned technical problems, the present invention provides a smart unmanned vehicle for package pickup, comprising:

[0006] The vehicle includes a front end, a chassis, and side panels vertically arranged on both sides of the chassis. The top of the chassis has several storage cavities vertically arranged, each storage cavity being a cover-shaped structure with its opening horizontally outward.

[0014] The invention is further configured such that the take-up drum is located above the through-hole, or:

[0015] Each of the through-holes is horizontally rotatably provided with a drag-reducing column. The blocking member moves around the upper side of the drag-reducing column. The top of the storage cavity is provided with several pairs of guide plates. The blocking strip located between the drag-reducing column and the winding drum is located between two of the guide plates. The side of the guide plate is provided with a guide groove for the blocking strip to move through.

[0016] The present invention is further configured such that all the take-up drums on the same side are coaxial, and a through-hole is provided horizontally through the middle of the take-up drum, and a linkage bar is provided on the inner wall of each take-up drum;

[0017] The drive mechanism includes:

[0018] The support base has two supports, and a drive column is horizontally rotatably arranged between the two supports. The drive column passes through all the through holes in the same column, and an adjustment channel is opened in the middle of the drive column. A long strip-shaped linkage port is opened in the middle of the drive column.

[0019] A drive motor is provided to drive the drive column to rotate.

[0020] The fixed base has two fixed bases, and two support bases are located between the two fixed bases. A fixing screw is horizontally fixed between the two fixed bases. The fixing screw is coaxial with the adjustment channel, and the outer wall of the fixing screw is separate from the inner wall of the adjustment channel.

[0021] A lead screw cylinder is sleeved on the outer wall of the fixed lead screw and threadedly engaged with the fixed lead screw. The outer wall of the lead screw cylinder is separated from the inner wall of the adjustment channel. The outer wall of the lead screw cylinder is provided with a lead screw portion that passes through the linkage port.

[0022] A drive cylinder is movably sleeved on the outer wall of the drive column, and the outer end of the lead screw is fixedly connected to the inner wall of the drive cylinder.

[0025] The present invention is further configured such that the free end of the drive seat is provided with a telescopic opening, and both sides of the telescopic opening are provided with anti-detachment openings communicating with the telescopic opening. The telescopic opening has a rectangular cross-section. The drive part is movably attached to the inner wall of the telescopic opening. Both ends of the drive part are provided with anti-detachment parts. The two anti-detachment parts respectively move through the two anti-detachment openings. A first elastic member that is continuously in a compressed state is provided between the inner end of the drive part and the inner end of the telescopic opening.

[0026] The adjustment mechanism includes a hinge seat disposed on the side of the drive cylinder. The free end of the hinge seat has a hinge groove.

[0029] The top of the storage cavity is provided with an unlocking seat, and the top of the unlocking seat is provided with an unlocking ring coaxial with the drive column. When the unlocking arm abuts against the unlocking ring, the locking part moves to the side of the anti-detachment part, and the drive part moves outward.

[0030] The present invention is further configured such that a stabilizing part is provided on both sides of the driving part, the longitudinal section of the stabilizing part is triangular, and a plurality of linkage bars and the driving part are provided, and a stabilizing groove for the stabilizing part to be inserted is provided in the middle of both sides of each linkage bar.

[0031] The chassis has several storage cavities arranged symmetrically on both sides, and all the winding drums are arranged in two rows.

[0032] The present invention also provides the application of any of the above-mentioned intelligent unmanned pickup vehicle in unmanned tobacco delivery services.

[0033] Compared with existing technologies, this invention provides a smart unmanned pickup vehicle and its application in unmanned tobacco delivery services. Firstly, the connection between the pickup door and the pickup opening can be a mechanical lock or a combination lock (both are the same as products sold on the market), or a bolt, etc., to allow all merchants to open it. Since the purpose of the pickup door is only to prevent internal objects (such as cartons of cigarettes) from falling out, it also serves to limit and support internal objects, thus protecting the blocking strip. Simultaneously, multiple monitors can be installed on both sides of the side panel to monitor whether the user is operating normally, such as whether the pickup door is opened and closed correctly, and whether the blocking strip is operated after the corresponding object is retrieved. If any incorrect operation is detected, the unmanned vehicle will automatically issue an alarm and report the relevant information to the control center.

[0034] When a merchant retrieves the corresponding goods, the drive mechanism first drives the take-up drum to rotate and winds a set length of blocking strip around the take-up drum. This causes the bottom of the take-up drum to rise to a certain height, and the object retrieved by the user is in a state that can be taken out after the blocking strip is raised.

[0035] After a merchant retrieves their goods, they simply close the retrieval door. If the items in the storage cavity are not completely removed, the corresponding barrier bar will not descend but will rise again when the next merchant arrives. Since there are multiple storage slots and the number of shelves can be adjusted according to actual needs, the number of spaces each storage cavity can be divided into and the capacity of each space can be adjusted as needed. (Each time the barrier bar rises, one space is exposed and opened). Thus, even though the total capacity of all storage cavities is fixed, the number of merchants that can be delivered can be manually adjusted. Furthermore, even if one or several merchants have a large amount of goods, the desired effect can be achieved by adjusting the use of the shelves, resulting in better usability.

[0036] It should also be noted that when the position and / or number of shelves are adjusted, the program used to drive the winding drum needs to be designed separately. Additionally, the inner end of the shelf preferably has rubber protrusions to improve positional stability with the storage cavity, preventing parts of the shelf from impacting the retrieval door.

The fixing screw 25 is coaxial with the adjustment channel 22, and the outer wall of the fixing screw 25 is separated from the inner wall of the adjustment channel 22.

[0068] A lead screw cylinder 26 is sleeved on the outer wall of the fixed lead screw 25 and threadedly engaged with the fixed lead screw 25. The outer wall of the lead screw cylinder 26 is separated from the inner wall of the adjustment channel 22.

[0078] The chassis 2 has several storage cavities 4 arranged symmetrically on both sides, and all the winding drums 10 are arranged in two rows.

[0079] The present invention also provides the application of any of the above-mentioned intelligent unmanned pickup vehicle in unmanned tobacco delivery services.

[0080] This invention provides an intelligent unmanned pickup vehicle and its application in unmanned tobacco delivery services. Firstly, the connection between the pickup door 6 and the pickup opening 5 can be a mechanical lock, a combination lock (similar to commercially available products), or a bolt, allowing all merchants to open it. The purpose of the pickup door 6 is solely to prevent internal objects (such as packs of cigarettes) from falling out, while also providing restraint and support for internal objects, thus protecting the blocking strip 11. Simultaneously, multiple monitors can be installed on both sides of the side panel 3 to monitor whether the user is operating the vehicle correctly, such as whether the pickup door 6 is opened and closed properly, and whether the blocking strip 11 is operated after the corresponding object is retrieved. If any incorrect operation is detected, the unmanned vehicle will automatically issue an alarm and report the relevant information to the control center.

[0081] When the merchant takes out the corresponding goods, the drive mechanism first drives the take-up drum 10 to rotate and winds the stop bar 11 of a set length onto the take-up drum 10. In this way, the bottom of the take-up drum 10 will rise to a certain height, and the object taken out by the user will be in a state that can be taken out after the stop bar 11 is raised.

[0082] After a merchant retrieves their goods, they simply close the retrieval door 6. If the items in the storage cavity 4 are not completely removed, the corresponding blocking bar 11 will not descend but will rise again when the next merchant arrives. Since there are multiple storage slots 7, the number of storage panels 8 can also be adjusted according to actual needs. Thus, the number of spaces divided into each storage cavity 4 and the capacity of each space are adjustable. This allows for adjustments based on actual circumstances (each time the blocking bar 11 rises, one space is exposed and opened). Even though the total capacity of all storage cavities 4 is fixed, the number of merchants that can be delivered can be manually adjusted. Furthermore, even if one or several merchants have a large amount of goods, the desired effect can be achieved by adjusting the use of the storage panels 8, resulting in better usability.

[0083] It should also be noted that when the position and / or number of the storage trays 8 are adjusted, the program used to drive the winding drum 10 needs to be designed separately. Furthermore, the inner end of the storage tray 8 preferably has rubber protrusions to improve positional stability with the storage cavity 4, preventing parts of the storage tray 8 from impacting the retrieval door 6.

[0084] In actual delivery, the order of picking up goods is from one end of the storage cavity 4 to the other end. Goods within each storage cavity 4 are also picked up from bottom to top. For example, in this embodiment, picking starts from the storage cavity 4 at the rear of the vehicle. When the unmanned vehicle reaches the designated location, the drive motor first drives the drive column 21 to rotate via a belt or chain. Simultaneously, the several drive units 30 abut against the sides of the corresponding linkage bars 19. Thus, the drive column 21 drives the take-up drum 10 to rotate, and the blocking strip 11 is wound around the take-up drum 10. The blocking strip 11 can undergo elastic deformation, but it also has a certain strength (similar to a roller shutter door). The blocking strips 11 connected end to end can be wound around the winding drum 10, but it is difficult for the outside to deform it. This prevents the merchant picking up the goods from opening the blocking strip 11 from the side and peeping at the goods of other merchants. At the same time, if the merchant pushes the blocking strip 11 upward, the blocking strip 11 changes angle at the through-hole 13 and the entire blocking strip 11 can also deform to a certain extent, making it difficult to move the blocking strip 11 upward. Even if the winding drum 10 is located above the through-hole 13, after pushing the blocking strip 11 upward, the blocking strip 11 drives the winding drum 10 to rotate. However, since the drive unit 30 can limit the linkage strip 19, the winding drum 10 cannot continue to rise. In this case, it is preferable that the bottom blocking strip 11 is slightly lower than the upper shelf 8 for picking up goods. The purpose is that even if the blocking strip 11 is raised to a certain height by human operation, it cannot be higher than the upper shelf 8, so that the goods of the next merchant cannot be observed.

[0085] If the blocking strip 11 located at the top of the storage cavity 4 is guided and limited by the guide groove 17, it is difficult or impossible to manually push the blocking strip 11 upward because the blocking strip 11 is not very strong; and even if it is pushed, it will still be limited by the linkage strip 19. Moreover, the linkage strip 19 has stabilizing grooves 48 on both sides, and the drive unit 30 has stabilizing parts 47 on both sides. This ensures that the drive unit 30 not only has driving stability when driving the linkage strip 19, but also that the stabilizing parts 47 can stably limit the linkage strip 19 when the blocking strip 11 is raised by external force.

[0086] The blocking strips 11 are preferably connected by a connecting part (such as fabric) to each other. This makes the thickness of the blocking strips 11 series more uniform, which facilitates precise winding on the winding drum 10 and also reduces the occurrence of tangling.

[0087] After the unmanned vehicle stops, the barrier bar 11 quickly rises to the designated position. Then, the person picking up the goods opens the corresponding retrieval door 6. At this point, the goods to be retrieved are already in an open state, and the person can take them directly. Afterward, the retrieval door 6 is closed. Once the unmanned vehicle senses that the corresponding retrieval door 6 has closed, it starts and moves to the next designated position. After stopping, it drives the winding drum 10 to rotate.

[0088] When the goods in the storage cavity 4 are being retrieved, all downstream take-up drums 10 are in standby mode. While the drive unit 30 drives the take-up drum 10 to rotate, the drive seat 29, drive cylinder 28, lead screw 27, and lead screw drum 26 all rotate synchronously. Since the lead screw drum 26 is threadedly connected to the fixed lead screw 25, and the fixed lead screw 25 is stationary, the lead screw drum 26, lead screw 27, drive cylinder 28, drive seat 29, and drive unit 30 all move along the length of the drive column 21. After all the objects in a certain storage cavity 4 have been retrieved, the drive unit 30 separates from the linkage bar 19, and simultaneously, the drive cylinder 28, lead screw drum 26, and other structures move out of the through-hole 18. Afterwards, the blocking strips 11 at the empty storage cavity 4 move downwards under the weight of the counterweight 14, releasing all the wrapped blocking strips 11. Alternatively, depending on the situation, workers may need to manually pull the counterweight 14 downwards. If the counterweight 14 can automatically lower the blocking strips 11, then during the next loading, all the blocking strips 11 need to be raised again before loading, and then the counterweight 14 lowers all the blocking strips 11 again. The two ends of the counterweight 14 are attached to the inner wall of the retrieval opening 5, and its dovetail strip is movably engaged in the dovetail groove, further improving the lifting and lowering capability of the counterweight 14. It also protects the bottom blocking strip 11, preventing anyone from violently pulling it outwards.

[0089] Then, the drive cylinder 28 moves along the length of the drive column 21 into the next take-up drum 10. At this time, the angle of the next take-up drum 10 is fixed under the pulling force of the counterweight 14. This fixed angle facilitates the drive cylinder 28 to enter the corresponding through-hole 18. Specifically, since there are several (e.g., three) linkage bars 19 and drive units 30, when the drive unit 30 enters the new take-up drum 10, each drive unit 30 is positioned directly opposite the middle of two adjacent linkage bars 19. This can prevent the drive unit 30 from contacting the linkage bar 19 to the greatest extent and improve the winding stability.

[0090] After all the take-up drums 10 in the same column have finished winding, the drive drum 28 continues to move and separates from the last take-up drum 10. Then the drive drum 28 moves and causes the passive part 41 to abut against the inner wall of the active groove 44. Since the inner wall of the active groove 44 is frustoconical, the drive part 30 moves inward toward the telescopic opening 31. During its movement, one of the anti-detachment parts 33 abuts against the outer side of the locking part 37 (before the locking part 37 is acted upon by the anti-detachment part 33, the side of the locking member 36 near the drive drum 28 is attached to the inner wall of the hinge groove), and drives the locking part 37 to swing outward. Until a certain point, the anti-detachment part 33 moves past the locking part 37. At this time, under the thrust of the second elastic member 40, the locking part 37 rebounds and locks the outer side of the anti-detachment part 33.

[0091] Then the drive column 21 rotates in the opposite direction, at which time the drive cylinder 28 moves towards the rear of the vehicle. Since the drive part 30 is locked by the locking part 37 at this time, the drive part 30 will not act on the linkage bar 19, so all the take-up drums 10 will not be affected. After the drive cylinder 28 passes through all the take-up drums 10 again, the drive cylinder 28 continues to move until a certain node the unlocking arm 39 abuts against the unlocking ring 46 and drives the locking part 37 to swing. Then at a certain node the locking part 37 separates from the anti-detachment part 33. After that, under the pushing force of the first elastic member 34, the drive part 30 pops outward. Then the drive part 30 can re-enter the first take-up drum 10 and drive the take-up drum 10 to rotate.

[0092] It should also be understood that the top of the side plates 3 on both sides also has a protective cover for protecting the winding drum 10, which can play a role in waterproofing and preventing impurities.

[0093] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0094] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
