Description

Technical Field

[0001] This utility model relates to the field of unmanned delivery vehicle technology, and in particular to an unloading mechanism suitable for unmanned delivery vehicles. Background Technology

[0002] Driverless delivery vehicles are intelligent transportation devices that integrate technologies such as environmental perception, path planning, and automatic obstacle avoidance, primarily used for last-mile delivery scenarios. They require no human driver and can autonomously identify roads, pedestrians, and obstacles, traveling along preset or real-time optimized routes to accurately deliver packages to designated locations such as communities, campuses, and office buildings. The vehicle's design features a multi-compartment or box-type storage structure, coupled with physical or simple electronically controlled retrieval mechanisms, allowing users to conveniently retrieve their packages using a code. This effectively reduces labor costs in last-mile delivery and improves delivery efficiency, making it particularly suitable for short-distance, high-frequency last-mile logistics.

[0003] Currently, the storage structure of driverless delivery vehicles is mostly multi-compartment. While this design allows for compartmentalized storage of packages, it presents significant inconveniences in actual retrieval. Retrieval personnel must fully extend their hands into the compartments to retrieve the packages. If a package slips into the depths of a compartment due to transportation bumps, it becomes difficult to reach it with force, and the narrow space of the compartments can restrict movement, greatly reducing the convenience of retrieval. This is especially unfriendly to the elderly, children, or people with limited hand mobility. Furthermore, after passing through multiple transit points and undergoing multiple loading and unloading operations, the surface of the package easily accumulates dust, bacteria, and even contaminants. These bacteria not only adhere to the inner walls of the compartments during long-term storage of the package, causing cross-contamination, but also pose a certain hygiene risk if the retrieval personnel do not clean their hands promptly after handling the package.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0028] Example 1:

[0029] Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a delivery unloading mechanism suitable for unmanned delivery vehicles, including an unmanned delivery vehicle 1. An identification radar 2 is installed on the top of the unmanned delivery vehicle 1. The interior of the unmanned delivery vehicle 1 is provided with multiple storage compartments 3. A door panel 4 is hinged to one side of the storage compartment 3. A pull-out component 5 is provided between the bottom of the inner cavity of the storage compartment 3 and the door panel 4. A disinfection component 6 is provided between the top of the inner cavity of the storage compartment 3 and the door panel 4.

[0030] The identification radar 2 on the top of the unmanned delivery vehicle 1 is an existing component of the delivery vehicle body. This is existing technology, which is clearly known to those skilled in the art and will not be described in detail here. The storage compartment 3 is divided into multiple small compartments and large compartments to facilitate the storage of packages of different sizes. The door panel 4 and the internal electronic self-locking of the storage compartment 3 can lock the packages. The pull-out component 5 can work with the door panel 4 to achieve the effect of assisting in the flow of packages. The disinfection component 6 can disinfect the packages stored inside the storage compartment 3.

[0031] The pull-out assembly 5 includes a movable plate 501 disposed inside the storage compartment 3. A connecting frame 502 is hinged to one side of the movable plate 501. An extension frame 503 is movably connected inside the connecting frame 502. One side of the extension frame 503 is hinged to the door panel 4.

[0032] The movable plate 501 is set at the bottom of the inner cavity of the storage compartment 3. It works in conjunction with the connecting frame 502 hinged on one side and the extension frame 503 slidably connected inside the connecting frame 502. When the door panel 4 is opened, the extension frame 503 hinged to the door will move within the connecting frame 502 and stretch the movable plate 501 to move outward, so as to move the express delivery stored on the top of the movable plate 501 out of part of the inner cavity of the storage compartment 3.

[0033] Example 2:

[0034] Reference Figures 3-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, a positioning plate 504 is fixedly connected to one side of the inside of the connecting frame 502, and a first spring 505 is fixedly connected between one side of the positioning plate 504 and one side of the extension frame 503.

[0036] A first spring 505 is fixed between the positioning plate 504 and the extension frame 503. When the extension frame 503 moves to a certain position, the first spring 505 will be stretched to cooperate with the positioning plate 504 to unfold the connecting frame 502, so as to allow the movable plate 501 to move elastically.

[0037] Specifically, sliders 506 are fixedly connected to both sides of the bottom of the movable plate 501, and a groove 507 for use with sliders 506 is opened at the bottom of the inner cavity of the storage compartment 3.

[0038] By sliding the slider 506 and the groove 507, the stability of the movable plate 501 during movement can be improved, ensuring that the movable plate 501 is more stable.

[0039] Specifically, the movable plate 501 is internally fixedly connected with anti-slip strips 508, which are arranged in an array.

[0040] The anti-slip strips 508 are fixed to the top of the movable plate 501 in an array. During the movement of the driverless delivery vehicle 1, the anti-slip strips 508 can increase the friction between the vehicle and the delivery box, reducing the shaking and tipping of the delivery box.

[0041] Specifically, a baffle 509 is fixedly connected to one side of the top of the movable plate 501, and a limiting groove 510 is provided inside the connecting frame 502 to cooperate with the extension frame 503.

[0042] The baffle 509 is fixed to the rear side of the movable plate 501 to facilitate the pulling of the express box. The limiting groove 510 can limit the movement of the extension frame 503 and prevent the extension frame 503 from detaching from the interior of the connecting frame 502.

[0043] Specifically, the disinfection component 6 includes a positioning frame 601 and an L-shaped pipe 602. The positioning frame 601 is fixed to one side of the top of the inner cavity of the storage compartment 3. The L-shaped pipe 602 is disposed on one side of the positioning frame 601. A first positioning ring 603, which is fixed to the inner wall of the storage compartment 3, is fixedly connected to the surface of the L-shaped pipe 602. A cover plate 614 is fixedly connected to the surface of the L-shaped pipe 602. A disinfectant bag 604 is threadedly connected to the inside of the cover plate 614.

[0044] The positioning bracket 601 facilitates the protection of the L-shaped pipe 602, while the cover plate 614 fixed to the surface of the L-shaped pipe 602 is threadedly tightened with the disinfectant bag 604 for easy replacement and maintenance. The first positioning ring 603 facilitates the secure fixing of the L-shaped pipe 602 to the top of the inner cavity of the storage compartment 3, thereby preventing it from affecting the package and reducing the space occupied by the storage compartment 3.

[0045] Example 3:

[0046] Reference Figures 3-5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, a first one-way valve 605 is installed on the surface of the L-shaped pipe 602, a guide pipe 606 is connected to one side of the L-shaped pipe 602, a water supply pipe 607 is connected to one side of the guide pipe 606, a second one-way valve 608 is installed on the surface of the water supply pipe 607, and a spray shell 609 is connected to one end of the water supply pipe 607.

[0048] The first one-way valve 605 on the surface of the L-shaped pipe 602 can draw disinfectant into the interior of the guide pipe 606 under negative pressure. When the disinfectant flows back inside the guide pipe 606, the first one-way valve 605 will close again, and the second one-way valve 608 on the water supply pipe 607 will open, so that the disinfectant drawn out under negative pressure will be discharged into the interior of the spray shell 609 through the second one-way valve 608, thereby disinfecting the package. The opening of the second one-way valve 608 is located in the direction of the spray shell 609. It should be noted that a one-way valve is an automatic control valve that relies on the pressure of the medium itself or the action of external force to realize that the fluid liquid, gas, etc. flows only in one direction and prevents its reverse flow. The structure usually includes a valve body, a valve core and a return spring. When the positive pressure is greater than the reverse resistance, the valve core opens to allow flow, and when the reverse pressure is applied, the valve core closes to seal. This is existing technology, which is clearly known to those skilled in the art, and will not be described in detail here.

[0049] Specifically, a sealing plug 610 is provided inside the flow guide pipe 606, and a traction rope 611 is fixedly connected to one side of the sealing plug 610. One end of the traction rope 611 passes through to the outside of the flow guide pipe 606 and is fixedly connected to the door panel 4.

[0050] By setting the sealing plug 610 on one side inside the guide tube 606 and fixing it to the door panel 4 with the traction rope 611, the linkage operation can be realized. When the door panel 4 is opened, the traction rope 611 will be pulled to move the sealing plug 610 inside the guide tube 606, thereby drawing the disinfectant inside the disinfectant bag 604 into the guide tube 606 through the negative pressure of the L-shaped pipe 602 and the first one-way valve 605, so as to facilitate subsequent disinfection work.

[0051] Specifically, a second spring 612 is fixedly connected to one side of the sealing plug 610, and one end of the second spring 612 is fixedly connected to the inner wall of the guide tube 606.

[0052] By fixing the second spring 612 between the inner wall of the guide tube 606 and the sealing plug 610, the disinfectant drawn into the guide tube 606 under negative pressure can be pressurized and discharged into the water supply pipe 607 in conjunction with the second one-way valve 608, and finally discharged into the storage compartment 3 through the spray shell 609.

[0053] Specifically, a second positioning ring 613 is fixedly connected to the surface of the guide tube 606, and the top of the second positioning ring 613 is fixedly connected to the inner wall of the storage compartment 3.

[0054] The second positioning ring 613 is fixed to the surface of the guide tube 606, and its top is fixed to the inner wall of the storage compartment 3, which can help provide stable support for the guide tube 606.

[0055] In use, when staff need to place a package into storage compartment 3, they first open door panel 4. Door panel 4 then moves the traction rope 611 and sealing plug 610 to one side, compressing the second spring 612. As the sealing plug 610 moves, it opens in conjunction with the L-shaped pipe 602 and the first one-way valve 605, allowing disinfectant to be drawn into the guide pipe 606. After the courier places the package into storage compartment 3, they close door panel 4. The second spring 612 then resets the sealing plug 610, allowing the disinfectant drawn into the guide pipe 606 to be released through the second one-way valve 608. Pipe 607 is discharged into the interior of spray shell 609, thereby disinfecting the packages inside storage compartment 3. When a person picks up a package, the door panel 4 is opened in coordination with the control switch of the unmanned delivery vehicle 1. The person then pulls open the door panel 4, which causes the hinged extension frame 503 to move within the connecting frame 502. When the door panel 4 is opened to a certain position, the extension frame 503 stretches the first spring 505, causing the positioning plate 504 to move the connecting frame 502. As the connecting frame 502 moves, it causes the movable plate 501 to move in conjunction with the baffle 509, thereby moving a portion of the package to the outside of storage compartment 3 for easy retrieval by the person picking it up.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
