Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a towed UAV agricultural protection vehicle. Background Technology

[0002] Unmanned aerial vehicles (UAVs) used for agricultural and forestry plant protection operations, or agricultural drones for short, perform precise operations such as pesticide spraying, seed sowing, and fertilizer application via ground remote control or autonomous navigation. To address the challenges of long-term field operations for agricultural drones, they are often equipped with drone-mounted agricultural vehicles, thus solving problems such as power shortages, water shortages, and difficult takeoff and landing. Some drone-mounted agricultural vehicles have takeoff and landing decks on the roof of the vehicle, providing a flat and safe landing point even on muddy or uneven ground in the fields. While the drones are secured to the deck during transport to the work site, this leaves them exposed outside the vehicle, making them susceptible to damage during field transport. Utility Model Content

[0003] In view of this, in order to solve the problem that existing drone-mounted agricultural vehicles are prone to collisions and damage when transporting agricultural drones, the present invention provides a trailer-mounted drone-mounted agricultural vehicle.

[0004] An embodiment of this utility model provides a towed drone agricultural vehicle, comprising: The carriage has wheels at the bottom and a drone bay at the rear of the interior, with the rear of the carriage being open. A slide rail assembly includes a housing, an outer slide rail, and an inner slide rail. The housing is fixedly disposed at the bottom of the carriage along the front-rear direction. The outer slide rail is slidably disposed within the housing. The rear end of the housing is provided with a limiting block for limiting the rearward travel of the outer slide rail. The inner slide rail is slidably disposed within the outer slide rail. The front end of the outer slide rail is provided with a pushing block that can push the inner slide rail to move backward. The rear door is rotatably connected to the rear end of the outer slide rail, so that when the rear door is rotated to a vertical position, it can be connected to the carriage by a latch, and the rear door can be moved to a predetermined position at the rear of the carriage. The rear support leg is rotatably connected to the rear end of the inner slide rail. The rear support leg can move backward through the inner slide rail, so that the rear support leg moves to a predetermined position behind the rear door, and the rear door rotates to a horizontal state and is supported on the rear support leg.

[0005] Furthermore, a horizontally arranged pad is fixedly connected to the upper part of the rear support leg. The rear door rotates to a horizontal state and is supported on the pad. The rear end of the inner slide rail is connected to a moving beam. The middle part of the moving beam is detachably connected to the upper end of the rear support leg. The pad is fixed above the moving beam. A rear fixing seat is provided on the moving beam. The rear support leg can rotate to a horizontal state and be fastened to the rear fixing seat.

[0006] Furthermore, the vehicle includes a chassis and a compartment detachably connected to the chassis, the drone cabin is disposed in the compartment, and the slide rail assembly is disposed at the bottom of the chassis.

[0007] Furthermore, the number of slide rail assemblies is set to two, and the two slide rail assemblies are arranged in parallel at the bottom of the carriage. The rear ends of the inner slide rails of the two slide rail assemblies are respectively connected to the two ends of the moving beam.

[0008] Furthermore, it also includes an elastic element that connects the rear end of the outer slide rail to the rear door.

[0009] Furthermore, the outer shell, the outer slide rail, and the inner slide rail are all hollow cuboids. The limiting block is a limiting wheel, which is fixedly installed at the bottom of the outer shell and its upper part passes through the bottom surface of the outer shell. The pushing block is a pushing wheel, which is rotatably installed in the outer slide rail. The bottom of the pushing wheel passes through the bottom surface of the outer slide rail and rolls in contact with the bottom surface of the outer shell. When the pushing wheel moves to the limiting wheel, it is blocked by the limiting wheel.

[0010] Furthermore, the upper part of the outer slide rail is provided with a rotatable auxiliary wheel, which makes rolling contact with the top surface of the outer casing.

[0011] Furthermore, it also includes a front support leg, which is rotatably connected to the front end of the carriage, and has two rollers, which are disposed opposite to each other at the bottom of the carriage.

[0012] Furthermore, the carriage is also equipped with a water tank and an inverter, and there are door openings on both the left and right sides of the carriage, with roller shutters installed at the door openings.

[0013] Furthermore, the top of the carriage is equipped with a parking area.

[0014] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: This utility model provides a trailer-mounted drone agricultural vehicle. By setting a drone bay at the rear of the vehicle body, the rear door can be rotated to a vertical position and locked to the vehicle body via a latch, storing the drone inside the drone bay to prevent damage during transportation. When the drone needs to operate, the latch is opened, and the rear support legs are pulled backward individually. The inner rail slides within the outer rail, moving the rear support legs to a certain distance from the rear door. Then, the rear door is rotated to a horizontal position supported on the rear support legs, and the drone moves from the drone bay to the rear door. Pulling the rear door backward then moves the rear door, causing the outer and inner rails to move together until the pushing block and the limiting block abut against each other, moving the rear door to a certain distance from the rear of the vehicle body. This provides sufficient safe take-off and landing space for the drone, using the rear door as the drone's take-off and landing point. This facilitates the drone's entry and exit from the drone bay and its take-off and landing, combining the flexible operation of the drone with the vehicle's mobile support capabilities, significantly improving the efficiency of large-area agricultural protection.

[0021] It should be further noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please refer to Figure 1-4 The present invention provides a towed drone plant protection vehicle for agricultural operations such as pesticide spraying, which mainly includes a carriage 1, a sliding rail assembly 3, a rear door 2, and rear support legs 4.

[0023] The bottom of the carriage 1 is equipped with rollers 6. The rollers 6 are generally installed in pairs at the bottom of the carriage 1, and the carriage 1 moves by rolling under the action of external traction force.

[0024] The rear end of the carriage 1 is equipped with a drone bay 7, and the rear end of the carriage 1 is open. The drone bay 7 is used to store agricultural drones, and the exit of the drone bay 7 faces rearward, that is, towards the rear port of the carriage 1. In this way, agricultural drones can enter the drone bay 7 through the rear port of the carriage 1.

[0025] Please refer to Figure 5-7 The slide rail assembly 3 includes a housing 15, an outer slide rail, and an inner slide rail. The housing 15 is fixedly disposed at the bottom of the carriage 1 along the front-to-back direction. The outer slide rail is slidably disposed within the housing 15. A limiting block 18 is provided at the rear end of the housing 15 to limit the rearward travel of the outer slide rail. The inner slide rail is slidably disposed within the outer slide rail. A pushing block 20 is provided at the front end of the outer slide rail to push the inner slide rail backward. The outer track 16 can slide along the front-to-back direction within the housing 15 and pushes the inner track 17 backward together with it through the pushing block 20. The outer track 16 can no longer slide when the pushing block 20 abuts against the limiting block 18, while the inner track 17 can continue to slide backward.

[0026] The shapes of the outer shell 15, the outer slide rail, and the inner slide rail can be flexibly set according to actual application scenarios. For example, in this embodiment, the outer shell 15, the outer slide rail, and the inner slide rail are all hollow cuboids. The limiting block 18 is a limiting wheel, which is fixedly installed at the bottom of the outer shell 15 and its upper part passes through the bottom surface of the outer shell 15. The pushing block 20 is a pushing wheel, which is rotatably installed in the outer slide rail. The bottom of the pushing wheel passes through the bottom surface of the outer slide rail and rolls in contact with the bottom surface of the outer shell 15. When the pushing wheel moves to the limiting wheel, it is blocked by the limiting wheel. The upper part of the limiting wheel protrudes relative to the bottom surface of the outer shell 15. Therefore, when the pushing wheel on the outer track 16 slides to the limiting wheel, it will be blocked and cannot continue to slide backward.

[0027] In some embodiments, the upper part of the outer slide rail is provided with a rotatable auxiliary wheel 19, which rolls in contact with the top surface of the housing 15. Thus, under the combined action of the auxiliary wheel 19 and the push wheel, the outer track 16 can slide stably within the housing 15.

[0028] The rear door 2 is rotatably connected to the rear end of the outer track 16. When the rear door 2 is rotated to a vertical position, it is connected to the carriage 1 via a latch 21. Specifically, the lower end of the rear door 2 is hinged to the rear end of the outer track 16. For example, two hinges are provided, fixed to the bottom of the rear end of the outer track 16 and respectively connected to the lower end of the rear door 2. The latch 21 is generally a panel latch, and multiple latches are provided, respectively installed on the left and right rear ends of the carriage 1 and respectively connected to both ends of the rear door 2.

[0029] Please refer to Figure 8 In some embodiments, a horizontally positioned pad 13 is fixedly connected to the upper part of the rear support leg 4, and the rear door 2 rotates to a horizontal position and is supported on the pad 13. The rear end of the inner rail 17 of the slide rail assembly 3 is connected to a moving beam 14, the middle part of which is detachably connected to the upper end of the rear support leg 4. The pad 13 is fixed above the moving beam 14, and a rear fixing seat is provided on the moving beam 14. The rear support leg 4 can rotate to a horizontal position and be secured to the rear fixing seat. The rear fixing seat is generally a U-shaped seat; when the rear support leg 4 rotates to a horizontal position, it can be inserted into the rear fixing seat and locked with bolts to obstruct the transport of the towed drone agricultural vehicle.

[0030] In order to ensure the stable forward and backward movement of the rear support leg 4, the number of slide rail assemblies 3 is generally set to multiple. For example, in this embodiment, the number of slide rail assemblies 3 is set to two. The two slide rail assemblies 3 are arranged in parallel at the bottom of the carriage 1, and the rear ends of the inner slide rails of the two slide rail assemblies 3 are respectively connected to the two ends of the moving beam 14.

[0031] Because the rear door 2 has a large mass, to facilitate its rotation from a horizontal to a vertical position and close the rear end of the cargo compartment 1, this utility model of a towable drone agricultural vehicle also includes an elastic element 11. The elastic element 11 connects the rear end of the outer slide rail to the rear door 2, allowing the rear door 2 to easily rotate from a horizontal to a vertical position. For example, the elastic element 11 is a torsion spring, which, in conjunction with the hinge, generates torque on the rear door 2. Specifically, the hinge includes two rotating seats and a fixed shaft. The fixed shaft is fixed to the rear end of the outer slide rail. The two rotating seats are rotatably sleeved on both ends of the fixed shaft and connected to the rear door 2. The torsion spring is sleeved on the fixed shaft, and its two ends are respectively connected to the rear end of the outer slide rail and the lower end of the rear door 2. Furthermore, the number of torsion springs can be flexibly set to multiple according to actual application needs.

[0032] To address the issue of stable fixation after separation from the towing vehicle, this utility model includes a towed drone agricultural vehicle with a front support leg 5. The front support leg 5 is rotatably connected to the front end of the cargo box 1. Two rollers 6 are positioned opposite each other at the bottom of the cargo box 1. A front support bracket 12 is located at the rear end of the cargo box 1. The front support leg 5 is rotatably connected to the front support bracket 12, and a front fixing seat is provided on the front support leg 5. The front support leg 5 can rotate to a horizontal position and be secured to the front fixing seat. The front fixing seat is generally a U-shaped seat. When the front support leg 5 rotates to a horizontal position, it can be inserted into the front fixing seat and locked with bolts to obstruct the transport of the towed drone agricultural vehicle.

[0033] To meet the water and power supply needs of agricultural operations such as pesticide spraying, the carriage 1 is also equipped with a water tank 9 and an inverter 8, which are located at the rear of the drone cabin 7.

[0034] The vehicle compartment 1 has door openings on both its left and right sides, and roller shutters 22 are installed at the door openings. When it is necessary to water or charge the agricultural drone, simply open the roller shutters 22 to water or charge the agricultural drone.

[0035] In addition, the top of the carriage 1 is equipped with a landing area 10, which is used for temporary parking of agricultural drones during operation. In the event of muddy or uneven ground in the field, it provides a flat and safe take-off and landing point for agricultural drones, avoiding take-off and landing accidents caused by ground debris or slope.

[0036] Please refer to Figure 9 In some embodiments, the carriage 1 can also be configured as a detachable unit. Specifically, the carriage 1 includes a chassis 23 and a body detachably connected to the chassis 23. The drone cabin 7 is disposed within the body, and the sliding rail assembly 3 is disposed at the bottom of the chassis 23. The body can be detached from the chassis 23 and then installed on a truck or other engineering vehicle, allowing for integrated transportation.

[0037] Please refer to Figure 4This utility model provides a towable drone agricultural vehicle. When transporting agricultural drones, the drones are stored in the drone compartment 7 at the rear of the vehicle compartment 1. The rear door 2 is rotated to a vertical position and locked to the vehicle compartment 1 via a latch 21. Then, the rear support legs 4 and the front support legs 5 are rotated to a horizontal position and secured. The vehicle compartment 1 is then connected to the tractor. Under the traction of the tractor, the vehicle compartment 1 and the agricultural drones inside are transported to the work site, avoiding easy collisions and damage during transportation. When the agricultural drone arrives at the work site, the latch 21 is first opened to separate the rear door 2 from the vehicle compartment 1. The rear support leg 4 is pulled backward, and the inner rail 17 slides within the outer rail 16, moving the rear support leg 4 to a certain distance from the rear door 2. The rear support leg 4 is positioned in the middle of the rear door 2 when it is rotated to a horizontal position. The rear door 2 is then rotated to a horizontal position and supported on the rear support leg 4. The drone moves from the drone cabin 7 to the rear door 2. The rear door 2 is then pulled backward, causing the outer rail 16 and inner rail 17 to move together until the push block 20 abuts against the limit block 18, moving the rear door 2 to a certain distance from the rear end of the vehicle compartment 1. This provides sufficient safe take-off and landing space for the drone. The rear door 2 serves as the take-off and landing point for the agricultural drone, facilitating its entry and exit from the drone cabin 7 and its take-off and landing. This combines the flexible operation of the agricultural drone with the mobile support capabilities of the vehicle, significantly improving the efficiency of large-area agricultural protection.

It should be understood that these are relative concepts and can vary depending on different methods of use and placement; the use of these directional terms should not limit the scope of protection claimed in this application.

[0039] Where there is no conflict, the embodiments and features described above can be combined with each other.
