Description

Technical Field

[0001] The utility model relates to the technical field of intelligent vehicles, in particular to a double-cage unmanned delivery vehicle. Background Art

[0002] Cage carts are unit-sized mobile containerized equipment equipped with several casters for transporting and storing goods. They are a common cargo carrier in logistics, transit, and sorting. They enable rapid unloading, online sorting, and loading of goods, improving express delivery efficiency. During the logistics and transportation process, cage carts not only ensure the safety of materials, but also prevent clutter in sorted goods, saving time and effort during subsequent loading and unloading.

[0003] At present, cage trucks and logistics vehicles are independent of each other and have no connection. After the goods are loaded into the cage truck, they need to be moved to the logistics vehicle by manual labor or forklifts. After arriving at the destination or transfer point, the cage truck needs to be unloaded. Since the fully loaded cage truck is heavy (can reach about 400 kg), the handling efficiency is low, which extends the transportation time of express delivery and poses certain safety hazards.

[0004] While there are also solutions on the market that can automatically load and unload cage carts, such as the Chinese patent document with publication number CN 117922408 A, which discloses a courier delivery flipping mechanism and an unmanned delivery vehicle, these devices utilize a movably mounted loading member on the unmanned vehicle body. The movably mounted loading member is driven by the movable member and the connecting member, allowing the loading member to slide forward and backward under the guidance of a guide portion and flip over under the limiting action of the guide portion. By moving the loading member backward and then flipping it backward, the loading member can be positioned vertically, allowing the package to be directly pushed into the loading member. The loading member is then flipped forward and positioned horizontally, and finally moved forward to a predetermined position, completing the automatic loading of the package. However, this technical solution has the following shortcomings: 1. The cage car needs to be flipped 90 degrees during loading and unloading, causing the express parcels high in the cage car to flip over, which can easily cause the express parcels to be crushed under the action of gravity; 2. The unmanned vehicle can only load one cage car at a time and can only serve one branch point, which is inefficient; 3. The cage car is designed to bear vertical force, and its force points are concentrated at the bottom. The lateral bearing capacity is limited. When horizontal transportation is used, the service life of the cage car will be reduced; 4. When unloading, manual labor is required to wait for the delivery and pull the cage car out, which is time-consuming and labor-intensive. If it cannot be unloaded in time, the utilization rate of the unmanned vehicle will be reduced. Utility Model Content

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0031] In this utility model, unless otherwise specified or limited, the terms "assemble," "connect," "connect," "fix," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Figures 1 to 8 An embodiment of the double-cage unmanned delivery vehicle of the utility model is shown. The double-cage unmanned delivery vehicle of this embodiment includes a frame 1, the middle part of the frame 1 is hollow and the bottom is open, a soft canopy 5 is provided on the top of the frame 1, and a telescopic platform 2 is provided at the opening to extend toward the side of the frame 1 (according to the relevant requirements of road traffic regulations, the vehicle needs to drive on the right, so in this embodiment, the telescopic platform 2 extends to the right side of the frame 1), and a lifting mechanism 3 is provided on the frame 1, which is connected to the telescopic platform 2 to drive the telescopic platform 2 to rise and fall.

[0034] The dual-cage unmanned delivery vehicle of this embodiment has a hollowed-out frame 1 with an open bottom. A telescopic platform 2 is located at the opening, extending and retracting toward the side of the frame 1. This platform is raised and lowered by a lifting mechanism 3. When the telescopic platform 2 is extended, a cage trolley 4 is pushed onto the platform, which automatically pulls the trolley 4 into the frame 1 and raises it into position. To unload the trolley 4, the lifting mechanism 3 lowers the telescopic platform 2 until the trolley 4 touches the ground, at which point the platform 2 extends the trolley 4 toward the side of the frame 1, achieving automatic unloading. The double-cage unmanned delivery vehicle of this embodiment only requires the cage vehicle 4 to be raised, lowered and extended during loading and unloading, without the need for flipping, which helps to avoid damage to the express parcels inside the cage vehicle 4; two cage vehicles 4 can be loaded at one time, thereby doubling the transport capacity of the unmanned delivery vehicle and improving delivery efficiency; the cage vehicle 4 adopts vertical transportation, which matches the vertical force design of the cage vehicle 4 and avoids affecting the service life of the cage vehicle 4; automatic unloading can be achieved without manual receiving of goods, which is more convenient to use and helps to improve loading and unloading efficiency; a soft roof 5 is provided on the top of the frame 1. When the cage vehicle 4 is high, the soft roof 5 can be jacked up, so that a relatively high cage vehicle 4 can be loaded, and it has strong adaptability.

[0035] Furthermore, the dual-cage unmanned delivery vehicle of this embodiment includes side doors 6, which are arranged opposite the lifting mechanism 3 on either side of the vehicle frame 1 (side door 6 on the right side of the vehicle frame 1, and lifting mechanism 3 on the left side of the vehicle frame 1). This layout is rational and avoids mutual interference. The soft canopy 5 and side doors 6 work together to effectively prevent the cargo inside the vehicle frame 1 from getting wet, while also enabling private transportation. Before the telescopic platform 2 extends from the vehicle frame 1, the side doors 6 must be opened first. After the telescopic platform 2 retracts into the vehicle frame 1, the side doors 6 are closed.

[0036] As a preferred embodiment, the side door 6 can be a double door or a rolling door with a large opening, which is convenient for loading and unloading the cage car 4 and takes up little space itself.

[0037] See Figure 4 and Figure 5Furthermore, in this embodiment, the telescopic platform 2 includes a base plate 21, a first telescopic plate 22 mounted on the base plate 21, and a telescopic drive 23 for driving the first telescopic plate 22 to move relative to the base plate 21. The base plate 21 is connected to the lifting mechanism 3 (specifically, the lifting body 31). During operation, the lifting mechanism 3 drives the base plate 21 up and down, and the first telescopic plate 22 rises and falls synchronously with the base plate 21. The telescopic drive 23 then drives the first telescopic plate 22 to move relative to the base plate 21 to achieve the first stage of telescopic movement.

[0038] Furthermore, in this embodiment, the telescopic platform 2 also includes a second telescopic plate 24 disposed on the first telescopic plate 22. The second telescopic plate 24 is connected to the telescopic drive member 23 for movement relative to the first telescopic plate 22. Under the action of the telescopic drive member 23, the second telescopic plate 24 moves relative to the first telescopic plate 22 to achieve a second stage of telescopic extension. The two-stage telescopic structure increases the telescopic travel while reducing the overhang of the second telescopic plate 24, improving stability. Furthermore, the shared telescopic drive member 23 simplifies the structure and reduces costs.

[0039] Furthermore, in this embodiment, the telescopic drive member 23 is a first motor and is disposed on the first telescopic plate 22. The first motor's rotating shaft is provided with a drive gear 25 and a driving pulley 20. A rack 26 is provided on the base plate 21. The drive gear 25 meshes with the rack 26. The first telescopic plate 22 is provided with a driven pulley 27. A synchronous belt 28 is wound around the driving pulley 20 and the driven pulley 27. The second telescopic plate 24 is connected to the synchronous belt 28 (for example, the synchronous belt 28 is provided with a protrusion 281, which is fixedly connected to the second telescopic plate 24 via a threaded fastener). During operation, the first motor simultaneously drives the drive gear 25 and the driving pulley 20 to rotate. Since the rack 26 is mounted on the base plate 21 and remains fixed, the first telescopic plate 22 moves relative to the base plate 21. Since the second telescopic plate 22 is provided on the first telescopic plate 22, the second telescopic plate 24 will move with the first telescopic plate 22. At the same time, the active pulley and the driven pulley 27 drive the synchronous belt 28 to run, and the synchronous belt 28 can drive the second telescopic plate 24 to move relative to the first telescopic plate 22, so that the moving speed of the second telescopic plate 24 is the sum of the moving speed of the first telescopic plate 22 and the operating speed of the synchronous belt 28, thereby improving the operating efficiency of the second telescopic plate 24, increasing the telescopic stroke, and shortening the time required for the telescopic movement.

[0040] As a preferred embodiment, the first telescopic plate 22 is located in the middle of the bottom plate 21, and the second telescopic plate 24 is located in the middle of the first telescopic plate 22, which has good symmetry and force balance, and is conducive to maintaining stable operation of the telescopic platform 2.

[0041] In a preferred embodiment, the second telescopic plate 24 is a rectangular plate with horizontally arranged second motors 291 installed at the four corners of the rectangular plate. A locking block 29 is installed on the rotating shaft of the second motor 291. The second motor 291 can drive the locking block 29 to rotate in a vertical plane. When the cage trolley 4 needs to be loaded or unloaded, the second motor 291 drives the locking block 29 to rotate to a horizontal position to avoid interference. When the cage trolley 4 needs to be fixed to the second telescopic plate 24, the second motor 291 drives the locking block 29 to rotate to a vertical position, effectively preventing the cage trolley 4 from accidentally moving on the second telescopic plate 24. The structure is simple and reliable.

[0042] In a preferred embodiment, two telescopic platforms 2 are provided, each equipped with a lifting mechanism 3. These two telescopic platforms 2 can accommodate two cage carts 4, thereby multiplying the unmanned delivery vehicle's transport capacity. Furthermore, the two telescopic platforms 2 can be raised and lowered independently without interfering with each other. In other embodiments, only one lifting mechanism 3 may be provided, but this will result in the two telescopic platforms 2 being able to rise and fall only synchronously.

[0043] See Figure 6 Furthermore, in this embodiment, the lifting mechanism 3 includes a lifting body 31, a lifting guide rail 32 provided on the frame 1, and a lifting drive 33 for driving the lifting body 31 to move relative to the lifting guide rail 32. The lifting body 31 is connected to the telescopic platform 2 (specifically, the base plate 21), and the lifting guide rails 32 are arranged on both sides of the lifting body 31 and are slidably connected to the lifting body 31. Preferably, the lifting drive 33 is an electric push rod. Of course, in other embodiments, it can also be a gear rack pair, a synchronous belt mechanism, etc. During operation, the lifting drive 33 drives the lifting body 31 and the telescopic platform 2 to rise and fall as a whole. The lifting guide rails 32 on both sides provide guidance for the lifting body 31, ensuring a smooth lifting process and avoiding deviation.

[0044] Furthermore, in this embodiment, a guide groove 321 is provided on the lifting guide rail 32, and a roller 311 is provided on the lifting body 31. The roller 311 is located in the guide groove 321. The cooperation between the guide groove 321 and the roller 311 can provide a good guiding effect for the lifting body 31 to avoid deviation, and at the same time reduce the resistance of the lifting movement. The structure is simple and effective.

[0045] Furthermore, a connecting frame 34 is provided between the lifting guide rails 32 on both sides, and the lifting drive member 33 is provided in the middle of the connecting frame 34 , which has good symmetry and is conducive to achieving smooth lifting of the lifting body 31 .

[0046] See Figure 7 and Figure 8Furthermore, in this embodiment, the frame 1 includes a top connecting frame 11, a side connecting frame 12 and a bracket 13 provided at the lower part of the two ends of the top connecting frame 11, the upper part of the side connecting frame 12 is connected to the top connecting frame 11, and the two ends of the side connecting frame 12 are connected to the side of the bracket 13 (the telescopic platform 2 extends to the right, and accordingly, the side connecting frame 12 is connected to the left side of the bracket 13, which can maximize the space inside the frame 1 for loading the cage car 4 without affecting the loading and unloading of the cage car 4), the telescopic platform 2 is located between the brackets 13 at both ends, and the lifting mechanism 3 is provided on the side connecting frame 12.

[0047] Since the telescopic platform 2 extends to the right, the right sides of the brackets 13 at both ends cannot be connected as one. The top connecting frame 11 and the side connecting frame 12 can improve the connection strength of the brackets 13 at both ends, thereby improving the overall rigidity of the frame 1. At the same time, the side connecting frame 12 also facilitates the installation of the two lifting mechanisms 3.

[0048] The specific process of the delivery method of the double-cage unmanned delivery vehicle is as follows:

[0049] S1, loading the cage car 4: the lifting drive 33 drives the lifting body 31 and the telescopic platform 2 to descend as a whole until they touch the ground, the frame 1 is lifted up and separated from the ground, and the first motor drives the driving gear 25 and the active pulley 20 to rotate at the same time, and the first telescopic plate 22 and the second telescopic plate 24 are extended to the right side of the frame 1, and then the cage car 4 is manually pushed above the second telescopic plate 24, and the second motor 291 drives the locking block 29 to rotate to a vertical state, fixing the cage car 4 on the second telescopic plate 24, and the first motor drives the driving gear 25 and the active pulley 20 to rotate in the opposite direction at the same time, and the first telescopic plate 22, the second telescopic plate 24 and the cage car 4 are pulled back into the frame 1, and the lifting drive 33 drives the lifting body 31, the telescopic platform 2 and the cage car 4 to rise as a whole, so that the cage car 4 is off the ground, and the frame 1 descends to touch the ground. After the telescopic platform 2 rises to the set height, the cage car 4 lifts up the soft roof 5;

[0050] S2. Unloading the Cage Cart: After reaching the destination, the lifting drive 33 drives the lifting body 31, telescopic platform 2, and cage car 4 to descend as a whole, freeing the cage car 4 from contact with the ground. The frame 1 is lifted and separated from the ground. The first motor simultaneously drives the drive gear 25 and the active pulley 20 to rotate, and the first and second telescopic plates 22, 24, and cage car 4 extend to the right side of the frame 1. The second motor 291 drives the locking block 29 to rotate to a horizontal position. The first and second telescopic plates 22, 24 then retract into the frame 1, separating from the cage car 4, achieving automatic unloading, eliminating the need for manual handling. The lifting mechanism 3 drives the telescopic platform 2 upward, and the frame 1 descends to contact the ground. The dual-cage unmanned delivery vehicle then departs on its own to perform its next task or return to the destination.

[0051] The delivery method of the double-cage unmanned delivery vehicle can automatically pull the cage car 4 into the frame 1. When unloading the cage car 4 after arriving at the destination, the lifting mechanism 3 drives the telescopic platform 2 to descend so that the cage car 4 contacts the ground. The telescopic platform 2 drives the cage car 4 to extend to the side of the frame 1 to achieve automatic unloading. There is no need for manual receiving of the goods. It is very convenient to use and improves the loading and unloading efficiency. It can also load cage cars 4 that are relatively high and has strong adaptability.

Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations.
