Description

Technical Field

[0001] This application relates to the field of vehicle engineering technology, and in particular to a delivery vehicle. Background Technology

[0002] In order to make delivery more intelligent, companies in the logistics industry are trying unmanned delivery services. Unmanned delivery vehicles are a product that has emerged in response to the current last-mile delivery market and the development of autonomous driving. They are used to complete the transfer and delivery of cages and boxes.

[0003] Currently, the chassis of unmanned delivery vehicles is relatively high, which makes it impossible to transport the cages vertically. The cages can only be placed horizontally on the chassis, and loading and unloading of the cages requires the use of tilting mechanisms, which makes the loading and unloading operations complicated and not conducive to improving the operating efficiency of unmanned delivery vehicles. Summary of the Invention

[0004] The purpose of this application is to provide a delivery vehicle to solve the technical problem that the chassis of the existing unmanned delivery vehicle is too high, which makes it impossible to transport the cages vertically. The cages can only be placed horizontally on the chassis, and the loading and unloading of the cages requires the use of a tipping mechanism, which makes the loading and unloading operation complicated and not conducive to improving the operating efficiency of the unmanned delivery vehicle.

[0005] To achieve the above objectives, this application provides a delivery vehicle, comprising:

[0006] Chassis;

[0007] A tray is located at the rear of the chassis;

[0008] A lifting mechanism for lifting the tray;

[0009] The pallet includes a loading / unloading posture and a transport posture. When the pallet is in the loading / unloading posture, the height of the bearing surface of the pallet is less than the height of the mounting surface of the chassis, and the height of the bearing surface of the pallet when it is in the transport posture is greater than the height of the bearing surface when it is in the loading / unloading posture.

[0010] In one or more embodiments, it further includes:

[0011] The front wheel assembly is located at the front of the chassis;

[0012] A pair of rear wheels are arranged at the rear of the chassis, and each of the rear wheels is connected to the chassis via a rocker arm;

[0013] A storage space is formed between the pair of rear wheels, and the tray is arranged within the storage space.

[0014] In one or more embodiments, a protective element is further included, the protective element surrounding the outer periphery of the chassis, and the protective element includes a rear wheel cover covering the upper and inner sides of the rear wheel.

[0015] In one or more embodiments, a rear wheel cover is provided with a rear light.

[0016] In one or more embodiments, the vehicle body is also included, the vehicle body being disposed on the chassis, a baffle being disposed on the top of the rear side of the vehicle body, and when the pallet is in the transport posture, the box on the pallet abuts against the baffle to limit the box.

[0017] In one or more embodiments, side panels are also arranged on both sides of the rear face of the vehicle body. The side panels and the baffle cooperate to form a limiting space. When the pallet is in the transport posture, the box on the pallet is embedded in the limiting space.

[0018] In one or more embodiments, the width of the tray gradually decreases in the direction away from the chassis.

[0019] In one or more embodiments, the lifting mechanism is arranged on the chassis, and the working end of the lifting mechanism is connected to the tray.

[0020] In one or more embodiments, the lifting mechanism is a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod.

[0021] In one or more embodiments, the delivery vehicle is an unmanned delivery vehicle.

[0022] The advantages of this application, which differ from existing technologies, are:

[0023] The delivery vehicle of this application has a pallet connected to the rear of the chassis via a lifting mechanism. The pallet can lift the cage to achieve vertical loading of the cage. When the cage needs to be loaded, the height of the pallet can be lowered to be less than the height of the chassis's mounting surface, so that the cage to be loaded can be pushed flat onto the pallet. Then, the pallet is controlled to rise to achieve vertical loading of the cage. When the cage needs to be unloaded, the height of the pallet can be lowered to be less than the height of the chassis's mounting surface, and the cage can be pulled flat off the pallet. This helps to achieve efficient and automated loading and unloading of cages, improves the operating efficiency of unmanned delivery vehicles, and has a simple structure and low maintenance cost.

[0024] The chassis height of the delivery vehicle in this application can be set relatively low, which helps to improve the vehicle's passability and delivery stability. Attached Figure Description

[0041] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0042] Currently, the chassis of unmanned delivery vehicles are typically designed to be relatively high, with a cargo box section. Cages containing packages are placed horizontally inside the cargo box as a standard transport cage. Loading and unloading the cages requires moving them between the inside and outside of the cargo box, which is a complex operation and hinders the improvement of the operational efficiency of unmanned delivery vehicles.

[0043] To improve the loading and unloading efficiency of cages, a flipping mechanism for transporting cages is now being installed inside the cargo compartment of unmanned delivery vehicles. Although the flipping mechanism improves the loading and unloading efficiency of cages to a certain extent, its structural and maintenance costs are high, and the flipping time is long, which is not conducive to the rapid and automated loading and unloading of cages.

[0044] To address the aforementioned issues, the applicant has developed a delivery vehicle that, by altering the vehicle stacking arrangement and overall vehicle body form, greatly facilitates the automated loading, unloading, and transportation of cages by unmanned vehicles, thereby aiding in the automated loading and unloading of cages.

[0045] Specifically, please refer to Figure 1 , Figure 1 This is a structural schematic diagram of one embodiment of the chassis of the delivery vehicle of this application.

[0046] like Figure 1 As shown, the rear of the chassis 10 of the delivery vehicle is equipped with a pallet 20 and a lifting mechanism 30, which is used to lift the pallet 20.

[0047] Pallet 20 includes loading / unloading posture and transport posture. In loading / unloading posture, the height of the bearing surface of pallet 20 is less than the height of the mounting surface of the chassis, so that the box to be loaded can be pushed flat onto pallet 20. In transport posture, pallet 20 lifts the box so that the height of the bearing surface of pallet 20 is greater than the height of the bearing surface when in loading / unloading posture.

[0048] Specifically, in one embodiment, the pallet 20 is used to load a cage, which is a standard-sized transport cage with wheels on its bottom surface to facilitate transport of the cage. The size of the pallet 20 can be set to match the bottom surface of the cage, and the thickness of the pallet 20 can be less than the height of the wheels at the bottom of the cage, so that the pallet 20 can be embedded under the cage, making it easier for the pallet 20 to support the cage.

[0049] In this embodiment, the height of the pallet 20 bearing surface and the chassis 10 mounting surface is the distance relative to the surface supporting the delivery vehicle when the delivery vehicle is in normal working condition. For example, when the delivery vehicle is located on the ground of the work site, the distance between the pallet 20 bearing surface and the ground can be regarded as the height of the bearing surface. Correspondingly, the height of the bearing surface of the pallet 20 when it is in the transport posture is greater than the height of the bearing surface when it is in the loading and unloading posture. This can be understood as the distance between the bearing surface of the pallet 20 and the ground being smaller when it is in the loading and unloading posture.

[0050] The bearing surface of pallet 20 can be understood as a flat surface that supports the container to be loaded or unloaded, and the mounting surface of chassis 10 can be understood as a flat surface on which the vehicle body structure is arranged. Generally, in delivery vehicles that do not include pallet 20, the mounting surface of chassis 10 can also be understood as the bearing surface that supports the container, and the mounting surface of chassis 10 is limited by the vehicle body structure and usually does not have a small height to directly load and unload the container.

[0051] In this embodiment of the application, based on the structure of the chassis 10 described above, when loading and unloading cages, the lifting mechanism 30 can be used to lower the pallet 20 to a position where the height of the bearing surface is less than the height of the assembly surface of the chassis 10, and the cage can be directly pushed onto the pallet 20. Then, the lifting mechanism 30 can be used to lift the pallet 20 to lift the cage, and the cage can be transported by placing it vertically on the pallet 20, thereby realizing the rapid loading and unloading of the cage.

[0052] In addition, the lower height of the chassis 10 in the above-mentioned chassis 10 structure also improves the passability and stability of the delivery vehicle.

[0053] In some embodiments, when the pallet 20 is in the loading / unloading posture, the bearing surface of the pallet 20 may have different heights to accommodate transfer trolleys with different loading / unloading heights. Of course, in some embodiments, the pallet 20 may also be in the loading / unloading posture at its lowest height, and this application does not limit this.

[0054] In some embodiments, when the pallet 20 is in a transport posture, the height of the bearing surface of the pallet 20 can be the same as the height of the mounting surface of the chassis 10. This allows the mounting surface of the chassis 10 to partially bear the function of the cage by optimizing its arrangement. After the lifting mechanism 30 lifts the pallet 20 and raises the cage, the cage can be further pushed onto the bearing surface of the chassis 10 by translation, at least partially.

[0055] To improve the space utilization and stability of delivery vehicles, please refer to [link / reference needed]. Figures 1 to 3 , Figure 2 This is a structural schematic diagram of one embodiment of the delivery vehicle of this application. Figure 3 yes Figure 2 A top-view structural diagram.

[0056] like Figures 1 to 3 As shown, the delivery vehicle includes a front wheel assembly 40 located at the front of the chassis 10 and a pair of rear wheels 50 located at the rear of the chassis 10.

[0057] Each rear wheel 50 is connected to the chassis 10 via a rocker arm 80, thereby creating a storage space between the pair of rear wheels 50. A pallet 20 can be placed within the storage space to load the cage.

[0058] Based on the above design, the stability of the delivery vehicle during loading can be significantly improved, while the rear wheels 50 also provide side protection for the cage.

[0059] The delivery vehicle also includes a body 60 mounted on a chassis 1. In one embodiment, the delivery vehicle can be an unmanned delivery vehicle, and its electrical components and smart hardware can be arranged inside the body 60 and on the chassis 10. Based on this delivery vehicle structure, the delivery vehicle can also automatically perform cage loading operations.

[0060] Specifically, the delivery vehicle can identify the cage and automatically adjust the pallet 20 to be below the cage, and then automatically control the pallet 20 to rise to load the cage.

[0061] For further details, please refer to Figure 4 and Figure 5 , Figure 4 This is a structural schematic diagram of one embodiment of the vehicle body of this application. Figure 5 This is a schematic diagram of the loading state structure of one embodiment of the delivery vehicle of this application. For example... Figure 4 and Figure 5 As shown, in order to limit the loading of the cage 90, a baffle 601 is arranged on the top of the rear side of the vehicle body 60. When the pallet 20 is in the transport posture, the cage 90 on the pallet 20 can abut against the baffle 601 to limit the cage 90. Of course,

[0062] In order to further limit the cage 90, in this embodiment, side plates 602 are arranged on both sides of the rear face of the vehicle body 60. A pair of side plates 602 and baffles 601 cooperate to form a limiting space 603. When the pallet 20 is in the transport posture, the cage 90 on the pallet 20 can be embedded in the limiting space 603 to achieve further limiting.

[0063] To facilitate the pushing of the cage 90 onto the tray 20, such as Figure 3 As shown, the width of the pallet 20 gradually decreases in the direction away from the chassis 10, thereby forming inclined guide surfaces on both sides of the pallet 20. When the cage is pushed in, the guide surfaces can guide cages at different angles onto the pallet 20.

[0064] like Figure 1 As shown, in this embodiment, the lifting mechanism 30 is a hydraulic cylinder with one end connected to the chassis 10 and the other end connected to the pallet 20, thereby controlling the lifting of the pallet 20 through the hydraulic cylinder.

[0065] It should be noted that in this embodiment, the pallet 20 will apply a bending moment to the hydraulic cylinder under load. When selecting the model of the hydraulic cylinder, it should be ensured that the working end of the hydraulic cylinder can meet the requirements of the pallet 20 under the maximum load condition; that is, when the gravity and bending moment of the pallet 20 under the maximum load condition act on the working end of the hydraulic cylinder, the hydraulic cylinder can still control the stable lifting of the pallet 20.

[0066] Of course, in other embodiments, in order to further improve the lifting stability of the pallet 20, the lifting mechanism 30 may further include a guide rod structure arranged between the pallet 20 and the chassis 10 for limiting the lifting direction, etc., which will not be described in detail here.

[0067] This embodiment only shows one optional structure of the lifting mechanism 30; it is understood that in other embodiments, the lifting mechanism 30 can also be any mechanical component commonly used in the art capable of driving lifting, such as cylinders, electric telescopic rods, lead screws and nuts, and rotary motors, etc., all of which can achieve the effect of this embodiment. In particular, in other embodiments, in order to ensure the stability of the lifting of the tray 20, the lifting mechanism 30 may also include guide rails that match the tray 20, which are all conventional designs in the art and will not be described in detail here.

[0068] like Figure 2 and Figure 3 As shown, in order to protect the chassis 10 and rear wheels 50 of the delivery vehicle, the delivery vehicle in this embodiment also includes a protective component 70. The protective component 70 is arranged around the outer periphery of the chassis 10, and the protective component 70 includes a rear wheel cover 701 covering the upper and inner sides of the rear wheels 50, thereby preventing the cage from colliding with the rear wheels 50 during loading, unloading and transportation.

[0069] Furthermore, a rear light 702 is also arranged on the rear wheel arch 701.

[0070] Based on the above-described delivery vehicle, when the cage needs to be loaded, the pallet 20 can be lowered to its lowest position, the cage can be pushed onto the pallet 20, and then the pallet 20 can be raised to achieve vertical loading of the cage; when the cage needs to be unloaded, the pallet 20 can be lowered to its lowest position, and the cage can be pulled off the pallet 20. This helps to achieve efficient and automated loading and unloading of the cage, improves the operating efficiency of the unmanned delivery vehicle, and has a simple structure and low maintenance cost.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
