Description

Technical Field

[0001] This utility model relates to a vehicle-mounted drone transport protection device, which belongs to the category of industrial drone transport auxiliary equipment. Background Technology

[0002] Using drones for terrain surveying in the field of mining can significantly reduce the labor intensity of manual surveying and lower safety hazards in the field. However, due to the limited flight control distance of drones, they need to be transported to a suitable operating distance by surveyors during field surveying, typically via off-road vehicles. Drones used for surveying need to carry specialized surveying equipment, so most are large and heavy industrial drones. Vehicles traveling in the field experience more bumps than on regular roads, and drones and their onboard surveying modules contain numerous precision electronic components that are easily damaged by vehicle vibrations. Therefore, transporting industrial drones in the field presents a significant challenge. Furthermore, in extremely cold environments such as high-altitude areas, prolonged exposure of standby drones to extreme cold during transport can drastically reduce the lifespan of the drone's battery and electronic components, leading to irreversible battery damage and, in severe cases, a sudden voltage drop, causing the drone to lose control or crash in flight.

[0003] Chinese patent application CN202321779499.1 discloses a drone transport vehicle with heat preservation function, including a vehicle body, a cargo compartment, an installation structure, and a drone hangar. The installation structure is located inside the cargo compartment, and the drone hangar is located on the installation structure. Two storage cavities are located on both sides of the bottom of the drone hangar, and each storage cavity has a door. Each of the two storage cavities contains a battery heat preservation structure, which includes a cabinet, a cabinet door, a cross-shaped mounting plate, and a heater. The cross-shaped mounting plate divides the space inside the cabinet into four placement cavities. A mounting frame is located in the center of the cross-shaped mounting plate, and the heater is located within the mounting frame. This invention solves the problem that current drone transport vehicles lack a structure for heat preservation of backup drone batteries. The backup drone batteries carried on drone transport vehicles experience a decrease in power under low temperature and non-use conditions, resulting in insufficient battery power and unusability. However, the drone hangar in this solution is fixed inside the vehicle by an installation structure. Since drones need a relatively level parking platform during takeoff and landing, it is very difficult to find a flat ground to park the vehicle horizontally during field surveying operations. The vehicle's parking position needs to be adjusted multiple times to level the drone hangar. Moreover, many field surveying areas cannot even be accessed by transport vehicles, and manual handling is still required after the vehicle has been transported. This fixed-structure transport device is clearly not suitable for drone applications in complex terrain environments.

[0004] In addition, Chinese patent application number CN202021908491.7 discloses a constant temperature transport box for the battery of a formation drone. The disclosed technical solution provides a portable and mobile drone storage and transport box structure. The box structure can be transported with a vehicle, but the box is not easy to fix inside the vehicle when traveling in the field. The bumps of the vehicle can easily cause damage to the transport box and the drone inside due to collision. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a vehicle-mounted drone transportation protection device to address the transportation difficulties of industrial drones in field operations.

[0006] This utility model is achieved using the following technical solution:

[0007] A vehicle-mounted drone transport protection device includes an outer box 11, an inner box 12, and an anchoring connector 2. The drone and its accessories are fixedly placed inside the inner box 12, which is placed inside the outer box 11. A floating buffer 13 is provided between the outer wall of the inner box 12 and the inner wall of the outer box 11 to float the inner box 12 relative to the outer box 11. The outer box 11 and the vehicle carrying the drone are fixed together by the detachable anchoring connector 2.

[0008] As a preferred embodiment of this utility model, the anchoring connector 2 is further installed on the outer box 11, and the outer box 11 is provided with a fixing base 111 for installing the anchoring connector on the outside.

[0009] As another preferred embodiment of this utility model, the anchoring connector 2 is installed on the carriage of the drone, and the outer side of the outer box 11 is provided with a hook for connecting the anchoring connector.

[0010] In a vehicle-mounted drone transport protection device of this utility model, the anchoring connector 2 further includes an electric winch 21, an anchor cable 22, and a hook 23. The electric winch 21 is fixedly installed, the anchor cable 22 is wound around the winding end of the electric winch 21, and the hook 23 is connected to the far end of the anchor cable 22. The outer box of the drone and the vehicle are connected by the hook and the anchor cable. The entire box is anchored to the vehicle by tightening the anchor cable with the electric winch.

[0011] In a vehicle-mounted drone transport protection device of the present invention, the fixed base 111 or the vehicle body transporting the drone is provided with a power supply interface 112 for powering the electric winch 21, which can be directly powered by the vehicle power supply or the mobile power supply.

[0012] In a vehicle-mounted drone transport protection device of this utility model, the anchoring connector 2 includes four sets, which are symmetrically arranged on opposite sides of the bottom of the outer box to tighten and anchor the outer box 11.

[0013] In a vehicle-mounted drone transport protection device of the present invention, a fixed filler 121 is further provided inside the inner box 12, and the drone and its accessories are tightly embedded in the drone cavity 122 and accessory cavity 123 formed by the fixed filler 121, providing the inner box with the first layer of buffer protection for the drone and its accessories.

[0014] In a vehicle-mounted drone transport protection device of this utility model, the floating buffer 13 is further described as a spring or a shock-absorbing connecting pad, and the floating buffer 13 provides a second layer of buffer protection for the outer box to the inner box and the internal drone and storage compartment.

[0015] In a vehicle-mounted drone transport protection device of this utility model, the outer box 11 further includes an openable box cover to provide closed, all-round protection for the transported drone and its accessories.

[0016] In a vehicle-mounted drone transport protection device of the present invention, a heating module 3 is further included, wherein the heating module 3 includes a PTC heating element 31 laid at the bottom of the inner box 12.

[0017] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0018] (1) This utility model uses a detachable anchoring connector to fix the box containing the drone and its accessories to the carriage of the transport vehicle. When transported to the field operation area, the entire box structure containing the drone and its accessories can be removed from the transport vehicle by disassembling the anchoring connector. It is not necessary to adjust the parking posture of the vehicle to adapt to the horizontal state of the drone's parking platform. Because of the use of a movable box structure to transport the drone, even in more distant areas that cannot be reached by vehicles, the drone can be transported to a larger field operation range by combining vehicle transport and manual handling.

[0019] (2) The anchoring connectors set in the outer box of this utility model ensure the stability of the box containing the drone and its accessories relative to the vehicle compartment during vehicle transportation. At the same time, the box with multiple shock absorption protection is used to store the drone and its accessories. The fixed filler in the inner box fixes the drone and its accessories in the inner box, realizing the first layer of protection for the drone and its accessories. The inner box and the outer box are floated by floating buffers, realizing the second layer of protection for the inner box relative to the outer box, effectively absorbing external vibrations. Even when the vehicle is traveling in rugged wilderness, it still has a good anti-collision effect for the transported drone.

[0020] (3) The present invention also has a heating module inside the box, which can heat and keep the drone and its accessories in standby mode during transportation in extremely cold environments, maintain the stable temperature inside the box, reduce the damage to the drone battery and electronic components caused by low temperature during transportation, and extend the service life of the drone.

[0021] In summary, the vehicle-mounted drone transport protection device provided by this utility model enables safe and reliable transport of drones in field surveying operations, avoids collision damage caused by bumps during vehicle transport, improves the antifreeze properties of drones transported in extremely cold environments, and the detachable structure makes drone operation in the field more convenient. It can be promoted and applied in other situations where industrial drones are used for field operations.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0030] Example

[0031] See Figure 1 and Figure 2The illustrated vehicle-mounted drone transport protection device is a specific embodiment of this utility model, specifically including an outer casing 11, a fixed base 111, a power supply interface 112, an inner casing 12, a fixed filler 121, a drone cavity 122, an accessory cavity 123, a floating buffer 13, an anchoring connector 2, and a heating module 3. The drone and its accessories are fixedly placed inside the inner casing 12, which is placed inside the outer casing 11. A floating buffer 13 is provided between the outer wall of the inner casing 12 and the inner wall of the outer casing 11, allowing the inner casing 12 to float relative to the outer casing 11. The outer casing 11 and the vehicle carrying the drone are fixed together by a detachable anchoring connector 2.

[0032] The inner box 12 is a housing for directly storing the drone and its accessories. A fixed filler 121 is installed inside the inner box 12, and the drone and its accessories are tightly fitted within the drone cavity 122 and accessory cavity 123 formed by the fixed filler 121, providing the inner box with the first layer of cushioning protection for the drone and its accessories. The drone cavity 122 and accessory cavity 123 within the fixed filler 121 are integrally molded from foam material or elastic resin material according to the dimensions of the drone and its accessories, ensuring a tight fit. The fixed filler ensures that the drone and its accessories are fixed within the inner box 12 and provides cushioning between the drone and its accessories and the walls of the inner box 12. The drone accessories referred to here include, but are not limited to, the drone battery, remote controller, and onboard mapping module.

[0033] The floating buffer 13 between the outer casing 11 and the inner casing 12 is a spring or a shock-absorbing connecting pad. The floating buffer 13 provides a second layer of cushioning protection between the outer casing and the inner casing, as well as the internal drones and storage compartments. The shock-absorbing connecting pads are made of high-density shock-absorbing materials, such as sponge or silicone shock-absorbing pads. The floating buffer 13 is distributed between the side walls and the bottom surface between the inner and outer casings. The two ends of the floating buffer 13 are fixedly connected to the outer wall of the inner casing and the inner wall of the outer casing, respectively, so that the inner casing is floating relative to the outer casing.

[0034] The outer box 11 and inner box 12 of this embodiment also include an openable lid, providing enclosed all-around protection for the transported drone and its accessories. A sealing ring is provided between the lid and the box body to prevent dust and water from entering the box. The lid is hinged or snapped onto the top of the outer box 11, and the inner wall of the lid has a cushioning layer to buffer the impact of the drone hitting the lid after bumping and bouncing, thus providing all-around protection for the transported drone. In this embodiment, the lid is removed to demonstrate the internal structure of the device. The hinge or snap assembly structure between the lid and the box body is known technology, and those skilled in the art can choose to use known hinges or snaps to assemble the lid of this embodiment according to their needs.

[0035] The vehicle used to transport the drone in this embodiment is generally an off-road pickup truck. The pickup truck has a rear cargo box for carrying items. The anchoring connector 2 can be fixedly installed on the inner wall of the cargo box. Hooks for connecting the anchoring connector are provided on the outside of the outer box 11. In this solution, the anchoring connector 2 is installed on the cargo box, which can reduce the volume and weight of the entire drone transport box. Handles and wheels can also be added to the side of the box to facilitate the handling and transfer of the entire device.

[0036] Another approach in this embodiment is to install the anchoring connector 2 on the outer casing 11. A fixed base 111 for installing the anchoring connector is provided on the outside of the outer casing 11, and hooks for anchoring the connector are provided on the carriage. In this embodiment, the anchoring connector 2 is installed on the fixed base 111. The device comes with its own anchoring connector 2, so when the entire device is moved from the transport vehicle to another location, the anchoring connector 2 can be used directly to anchor and fix the outer casing.

[0037] See also Figure 3 In this embodiment, the anchoring connector 2 includes an electric winch 21, an anchor cable 22, and a hook 23. The electric winch 21 is fixedly installed on a fixed base 111 on the outside of the outer casing 11. The anchor cable 22 is wound around the winding end of the electric winch 21. The hook 23 is connected to the far end of the anchor cable 22. The hook 23 pulls the anchor cable 22 from the electric winch 21 and hooks it onto the hook on the vehicle body, connecting the outer casing of the drone transporting vehicle to the vehicle body. The electric winch 21 tightens the anchor cable 22 to anchor the entire outer casing to the vehicle body. Using an electric winch facilitates power supply from the vehicle's power supply. The electric winch structure can be selected from existing electric winch devices on off-road rescue vehicles. The fixed base 111 is provided with a power supply interface 112 for powering the electric winch 21, which is powered by the vehicle's power supply or a mobile power source. The power supply interface 112 adopts an existing general electrical interface to realize the electrical connection between the vehicle power supply or external power supply and the electric winch. At the same time, a port for charging drones can also be integrated through the power supply interface.

[0038] In this embodiment, the anchoring connectors 2 include four sets, symmetrically arranged on opposite sides of the bottom of the outer box 11 to tighten and anchor the outer box 11. During the vehicle's transportation of the drone, the anchoring connectors fixed on both sides of the bottom of the outer box 11 limit the overall position of the box on the plane of the bottom surface of the box. The fixed filling material inside the inner box 12 provides cushioning for the shaking experienced by the drone during vehicle movement. At the same time, this embodiment also adopts a double-layer buffer structure in which the inner box 12 floats relative to the outer box 11. The floating buffer 13 between the inner box 12 and the outer box 11 further reduces the vibration transmitted to the drone from vehicle bumps. This multi-fixed buffer structure can effectively protect the drone and its accessories even when the vehicle experiences large bumps and swaying during off-road driving.

[0039] Combined with Figure 4 , in the on-vehicle UAV transportation protection device of this embodiment, there is also a heating module 3. The heating module 3 includes a PTC heating sheet 31 laid at the bottom of the inner box 12. The PTC heating sheet 31 does not directly contact the fixed filler 121 inside the inner box 12. The PTC heating sheet 31 and the fixed filler 121 are separated by a metal partition with uniform heat conduction, and the heat is evenly conducted to the internal space of the inner box through the metal partition, avoiding overheating and combustion of the filler. In addition, the box wall of the inner box 12 is made of stainless steel or aluminum alloy. While having high structural strength, it can evenly absorb the heat of the PTC heating sheet and then reflect it to the UAV and its accessories fixed inside for heating and heat preservation, avoiding damage to the standby UAV battery and electrical components due to low temperature during transportation. The temperature control module supporting the PTC heating sheet 31 is embedded in the inner box, including a temperature display unit, a temperature sensing unit, and a wiring interface electrically connected through a temperature control circuit. The temperature control module is energized through the wiring interface to drive the PTC heating sheet 31 to generate heat. The temperature sensing unit detects the heating temperature of the PTC heating sheet 31 and feeds back to the temperature control module to realize heat preservation of the UAV transported in the box body, and cuts off the temperature control circuit of the PTC heating sheet when the preset safety temperature is exceeded. The temperature detected by the temperature sensing unit is transmitted to the temperature display unit for real-time display. The temperature control module of the PTC heating sheet is an existing mature product. Those skilled in the art can obtain the corresponding temperature control circuit according to different PTC heating sheet products purchased. This embodiment will not be elaborated here.

[0040] The usage method of the on-vehicle UAV transportation protection device in this embodiment is as follows:

[0041] First, connect and anchor the outer box 11 to the cargo compartment of the transport vehicle using the anchoring connector 2. Place the drone and its accessories into the drone cavity 122 and accessory cavity 123 in the inner box 12. Power the heating module 3 through the vehicle's power supply and adjust the internal temperature of the box to a suitable level. Check that the floating buffer 13 between the inner box 12 and the outer box 11 is intact to ensure the device's shockproof performance. After all checks are completed, close the box lid to ensure good dustproof and waterproof performance before transporting the drone. Upon arrival at the drone's operating area, if the drone can be operated directly from the transport vehicle, open the box lid and remove the drone for operation. If further manual movement of the drone to the operating area is required, remove the entire protective device box structure from the vehicle by disassembling the anchoring connector 2 and manually move the device box to transport the drone. By using this device to transport drones, the bumps and vibrations experienced by drones during field travel can be greatly reduced, ensuring safe and reliable transport of drones. It can also protect drones and their accessories transported in extremely cold weather, preventing them from freezing and being damaged in the cold environment, extending the lifespan of drones and batteries, and improving the accuracy of drone measurements in extremely cold weather.
