Description

Technical Field

[0001] The present invention relates to the technical field of logistics transportation equipment, and particularly to a transport vehicle adaptable to all terrains. Background Art

[0002] With the booming development of e-commerce and the rise of new consumption, people's consumption habits have undergone earth-shaking changes. However, in sharp contrast to the exponential growth in the number of express deliveries and takeaways, the number of couriers and food delivery riders is seriously insufficient. Extreme weather conditions such as heavy rain and heavy snow, as well as unstructured roads like stairs, etc., will bring great interference to the delivery work. In rural areas, the roads are rough and the areas are vast, and the distance between users and relay stations is often very far. Therefore, the "last mile" delivery problem urgently needs more manpower input to optimize and solve.

[0003] To address the shortage of couriers and food delivery riders and the "last mile" delivery problem, in 2024, the large-scale application of new energy unmanned delivery vehicles was strongly encouraged, and the road rights, safety standards and supervision measures were clarified. Among them, the "Transportation Large-scale Equipment Renewal Action Plan" focused on promoting unmanned vehicle technology to accelerate the standardized development process of the industry.

[0004] Against this background, many express companies have actively engaged in the research and development of unmanned delivery vehicles. Zhongtong's unmanned vehicle has achieved station coverage within a 15-kilometer range in Yancheng and can handle 5% of the daily parcel volume of the network; Cainiao Station has cooperated with universities to directly deliver express deliveries from the station to the dormitory buildings, providing convenient services for teachers and students in universities. Meituan, a giant in the food delivery field, is also fully engaged in the research and development of unmanned delivery vehicles and plans to apply them to the food delivery business. Looking internationally, Marble Company in the United States has cooperated with Yelp to develop food delivery robots, and users can open the storage box of the robot to pick up food with a verification code; the fully automatic driverless delivery vehicle launched by Nuro can run freely on urban roads, and is equipped with heating and cooling equipment inside to achieve precise delivery of fresh-keeping goods. Although certain progress has been made in the field of unmanned delivery by all parties, for rural areas with complex and diverse terrains and vast areas, no effective solution to the "last mile" delivery problem has been truly found yet. Summary of the Invention

[0005] To solve the technical problems existing in the above background art, the present invention proposes a transport vehicle adaptable to all terrains.

[0006] To achieve the above object, the present invention provides the following technical solutions:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figures 1-6 shown, this embodiment provides a transport vehicle adaptable to all terrains, including:

[0028] A vehicle body 1, a main crawler wheel 2 is installed at the bottom of the vehicle body 1, a first auxiliary crawler wheel 3 is installed at one end of the vehicle body 1 where the main crawler wheel 2 is located, a second auxiliary crawler wheel 7 is installed at the other end of the vehicle body 1 where the main crawler wheel 2 is located, and the main crawler wheel 2, the first auxiliary crawler wheel 3, and the second auxiliary crawler wheel 7 are all driven by hydraulic motors;

[0029] A balance body 9, the balance body 9 is movably installed in the inner cavity of the vehicle body 1, and a cylindrical groove 11 is opened on the side wall of the vehicle body 1, and the balance body 9 is coaxially arranged with the cylindrical groove 11;

[0030] A tray 6, the tray 6 is installed on the balance body 9. When the vehicle body 1 performs a climbing action, the tray 6 can rotate with the balance body 9 to adjust the overall center of gravity position of the transport vehicle, so that the transport vehicle is more stable during the climbing process.

[0031] Overall, when the entire transport vehicle is traveling on a normal road surface, at this time, the first auxiliary crawler wheel 3 and the second auxiliary crawler wheel 7 are in a retracted state, and the main crawler wheel 2 is driven by a hydraulic motor to rotate to realize the advancement of the entire transport vehicle; when the transport vehicle needs to perform transportation on a certain slope, first, the hydraulic motor is used to deploy the first auxiliary crawler wheel 3 and the second auxiliary crawler wheel 7, so that the first auxiliary crawler wheel 3 is in the same extension direction as the main crawler wheel 2, and under the drive of the hydraulic motor, a torque is generated to lift the vehicle body 1, so that the included angle formed by the second auxiliary crawler wheel 7 and the main crawler wheel 2 is the same as the slope. At this time, the second auxiliary crawler wheel 7 provides power for the whole vehicle. When the whole vehicle is completely on the slope surface, the hydraulic motor drives the second auxiliary crawler wheel 7 to rotate, so that the main crawler wheel 2, the first auxiliary crawler wheel 3, and the second auxiliary crawler wheel 7 are all in contact with the slope surface, and they climb under the drive of the hydraulic motor. In order to prevent the entire transport vehicle from tipping over during the climbing process, when the transport vehicle is climbing, the balance body 9 can rotate axially around the cylindrical groove 11 due to its own weight and drive the entire tray 6 to rotate, which can keep the packages inside the vehicle body 1 always in a vertically upward state. At the same time, the center of gravity is lowered to improve the stability of the transport vehicle during the climbing process and prevent the packages from tipping over.

[0032] As Figure 5As shown, in this embodiment, the balance body 9 includes a cylindrical side plate 91, a second top plate 92, and a balance block 93. The cylindrical side plate 91, the second top plate 92, and the balance block 93 are of an integral structure. The cylindrical side plate 91 is coaxially arranged with the cylindrical groove 11, and the working surface of the balance block 93 is arranged parallel to the second top plate 92.

[0033] Specifically, the balance body 9 includes a cylindrical side plate 91, a second top plate 92, and a balance block 93. By designing the cylindrical side plate 91, the second top plate 92, and the balance block 93 as an integrated structure, the stability of the overall structure of the balance body 9 can be improved, and the stability of the packages on the tray 6 can be further enhanced. By arranging the working surface of the balance block 93 parallel to the second top plate 92, the storage space formed by the cylindrical side plate 91, the second top plate 92, and the balance block 93 can be further increased, facilitating the placement of the entire tray 6.

[0034] Specifically, a vehicle door 5 is provided at the opening position of the cylindrical groove 11. The vehicle door 5 is symmetrically arranged with respect to the cylindrical groove 11 and can move along the extension direction of the main track wheel 2. When the transporter is transporting packages, the vehicle door 5 is in a closed state.

[0035] As Figures 1-2 shown, in this embodiment, the tray 6 includes a bottom tray 61, a middle tray 62, and a top tray 63. The bottom tray 61, the middle tray 62, and the top tray 63 are arranged parallel to each other in pairs. A first rod 64 and a second rod 65 are hinged to the side walls of the bottom tray 61 and the middle tray 62, a third rod 66 is hinged to the side walls of the middle tray 62 and the top tray 63, and a hydraulic cylinder 67 is hinged to the side walls of the bottom tray 61 and the top tray 63. The first rod 64, the second rod 65, and the third rod 66 are arranged parallel to each other in pairs.

[0036] Specifically, the overall structure of the tray 6 is a three - layer folding design. During the low - peak period of package delivery, by contracting the hydraulic cylinder 67, the first rod 64, the second rod 65, and the third rod 66 can all rotate around the hinge points, reducing the distance between the bottom tray 61 and the middle tray 62 and also reducing the distance between the middle tray 62 and the top tray 63. This can not only save space but also lower the overall center of gravity formed by the tray 6 and the balance block 93, further improving the stability of the transporter during slope transportation and preventing the packages from tipping over. During the peak period of package delivery, by extending the hydraulic cylinder 67, the first rod 64, the second rod 65, and the third rod 66 can all rotate around the hinge points, increasing the distance between the bottom tray 61 and the middle tray 62 and also increasing the distance between the middle tray 62 and the top tray 63, which can further improve the space utilization rate inside the transporter.

[0037] As Figure 2 and Figure 5As shown, in this embodiment, a fitting block 68 is provided on the bottom surface of the bottom tray 61, and a fitting groove 94 adapted to the fitting block 68 is formed on the working surface of the balance block 93.

[0038] Specifically, the fitting block 68 on the bottom surface of the bottom tray 61 is adapted to the fitting groove 94 on the working surface of the balance block 93, which can effectively improve the stability between the balance block 93 and the tray 6 and also facilitate the installation and disassembly between the two.

[0039] As Figure 1 and Figure 6 As shown, in this embodiment, it further includes a box body 4, and the box body 4 is installed at the top of the vehicle body 1 and is of a foldable structure.

[0040] When the capacity inside the transporter cannot accommodate all the packages, by installing the box body 4 at the top of the vehicle body 1, the overall express carrying capacity of the transporter is improved.

[0041] As Figures 3-4 As shown, in this embodiment, it further includes a robotic arm 8. A slide rail 12 consistent with the extending direction of the main track wheel 2 is provided at the top of the vehicle body 1. The robotic arm 8 is installed on the slide rail 12, and the robotic arm 8 can move along the path of the slide rail 12.

[0042] For the convenience of express sorting and distribution, and to further improve the automation degree of the packages during transportation, the robotic arm 8 is installed on the slide rail 12 at the top of the vehicle body 1, and the robotic arm 8 is a six - degree - of - freedom robotic arm 8, which can effectively improve the efficiency of the packages during sorting and distribution. During the process of the robotic arm 8 sorting and distributing, the vehicle door 5 is in an open state.

[0043] As Figure 6 As shown, in this embodiment, the box body 4 includes a first side plate 41, a first top plate 42, a second side plate 43 and a third side plate 44. The first top plate 42 is arranged opposite to the top of the vehicle body 1. The long side of the second side plate 43 is hinged to the long side of the top of the vehicle body 1. The long side of the third side plate 44 is hinged to the long side of the first top plate 42. The other long side of the second side plate 43 is hinged to the other long side of the third side plate 44. The short side of the first side plate 41 is hinged to the short side of the top of the vehicle body 1.

[0044] Specifically, the box body 4 is of a foldable structure. When the box body 4 is in an idle state, the short side of the first side plate 41 rotates around the short side hinge shaft at the top of the vehicle body 1, and both first side plates 41 are embedded in the top of the vehicle body 1. Applying an inward force to the hinge shaft between the second side plate 43 and the third side plate 44 can cause the second side plate 43 to rotate around the long side of the top of the vehicle body 1 and the third side plate 44 to rotate around the long side of the first top plate 42. In this state, it forms a ">" "<" shape. Then applying a downward pressure to the first top plate 42 can achieve the storage of the box body 4. When the box body 4 is needed to store packages, the first side plate 41, the second side plate 43 and the third side plate 44 are erected perpendicular to the roof of the vehicle. The first top plate 42 is parallel to the top surface of the roof, and the box body 4 can be unfolded and the packages can be stored in the box body 4 by buckling the vehicle pin of the first side plate 41 on the third side plate 44.

[0045] A box body 4 and a robotic arm 8 can also be installed on the top of the vehicle body 1, which can not only increase the express delivery capacity but also improve the efficiency of express delivery during sorting and distribution.
