Description

Technical Field

[0001] This utility model belongs to the field of vehicles for transporting unmanned aerial vehicles (UAVs), and in particular relates to a UAV transport vehicle. Background Technology

[0002] Because drones have long wingspans that exceed the width limits for road transport, the wings must be removed before transporting them.

[0003] Chinese invention patent CN108263632B, with an authorization announcement date of March 19, 2024, discloses a UAV transport and launch vehicle (hereinafter referred to as the transport vehicle). The transport vehicle includes a vehicle chassis, a wing storage compartment, a fuselage storage box, and an accessory compartment. The wing (equivalent to an outer wing) storage compartment is fixed to the vehicle chassis, the fuselage storage box is fixed to the center of the upper surface of the wing storage compartment, and the accessory compartment is vertically arranged and fixed to the top left end of the wing storage compartment. The wing storage compartment is equipped with a pull-out platform that can move left and right. The pull-out platform includes a fixed base fixed inside the wing storage compartment and a movable platform that moves horizontally with the fixed base in the left-right direction. The movable platform can partially extend out of the wing storage compartment when the compartment door is opened, facilitating the placement of the wing on the movable platform.

[0004] During transportation, the wings are stacked horizontally in the wing storage compartment, and the height of the wing storage compartment matches the total thickness of the two wings. When storing drones with compound wings (such as the FP-981C drone from Aerospace Era Feipeng Co., Ltd.), the height of the wing storage compartment also needs to be increased accordingly because the drone has many wings. The fuselage is fixed in the fuselage storage compartment with straps, and the height of the fuselage storage compartment matches the height of the fuselage.

[0005] In the prior art, the fuselage can also be fixed by locking the landing gear. For example, Chinese invention patent with authorization announcement number CN116620600B and authorization announcement date of 2025.05.06 discloses a vehicle-mounted drone platform. The drone platform includes a landing plate, and the landing plate is provided with a locking device for fixing the drone landing gear (i.e., fixing the landing gear).

[0006] The aforementioned transport vehicle has the following three drawbacks: (1) The height of the transport vehicle is not less than the sum of the height of the car chassis, the wing storage compartment and the fuselage storage compartment. Therefore, the height of the transport vehicle is relatively high and it cannot pass through some roads with low height restrictions (such as roads under overpasses and interchanges). (2) The height of the car chassis is relatively high, which makes the transport vehicle too high to pass through some roads with low height restrictions (such as roads under overpasses and interchanges). (3) The transport vehicle is a special truck, which has a high vehicle cost and requires a professional driver with a truck driver's license to drive it, resulting in a high labor cost. Utility Model Content

[0007] The purpose of this utility model is to provide a drone transport vehicle to solve the technical problem of the high height of the transport vehicle.

[0008] To achieve the above objectives, the technical solution for the unmanned aerial vehicle transport vehicle provided by this utility model is as follows: A drone transport vehicle includes a chassis and a storage compartment fixed to the chassis. The rear end of the storage compartment has an openable door. A pull-out platform located inside the storage compartment is connected to the chassis. The pull-out platform includes a fixed base fixed to the chassis and a movable platform that moves horizontally with the fixed base in the front-rear direction. The mobile platform can extend partially out of the storage compartment when the compartment door is opened, or the mobile platform can be separated from the fixed base; The moving platform is used in conjunction with the straps to secure the fuselage, or the moving platform is equipped with a locking device for securing the landing gear to the fuselage; The left and right side walls of the storage compartment are equipped with a first bracket for supporting the outer wings that extend vertically in width and longitudinally in length, and for cooperating with the straps to fix the outer wings.

[0009] Furthermore, the left and right side walls of the storage compartment are equipped with a second bracket for supporting the extended arms and for cooperating with the straps to fix the arms.

[0010] Furthermore, the second bracket is positioned above the first bracket.

[0011] Furthermore, the moving platform is also used to support the center wing, which is located between the fixed landing gears and extends longitudinally, and is used in conjunction with lashing straps to secure the center wing.

[0012] Furthermore, the first bracket includes a tray, one of the left and right sides of the tray is fixedly connected to the corresponding side wall of the storage compartment, and the other side is provided with a groove for horizontally placing the outer wing, and the lower wall of the groove is provided with a first receiving groove for accommodating the lower part of the outer wing.

[0013] Furthermore, the second bracket includes an L-shaped plate with a second receiving groove for accommodating the lower part of the arm.

[0014] Furthermore, the bottom of the moving platform is equipped with pulleys for suspending the moving platform when it slides with the fixed base.

[0015] Furthermore, the chassis is a trailer chassis.

[0016] Furthermore, the storage compartment is divided into a main storage compartment for storing the fuselage, outer wings, and arms; a secondary storage compartment for storing the vertical stabilizer; and an accessory compartment for storing the UAV's accessories. The secondary storage compartment is located directly above the accessory compartment, while the main storage compartment is located behind the secondary and accessory compartments.

[0017] Furthermore, the locking device includes a front stop, a rear stop, a left pressure plate, and a right pressure plate mounted on the moving platform. The distance between the front stop and the rear stop is adapted to match the front-to-back length of the fixed landing gear to limit the front-to-back position of the fixed landing gear. Each pressure plate is equipped with a motor for driving the pressure plate to rotate. The output shaft of the motor is connected to the left or right end of the pressure plate to press the pressure plate to fix the landing gear. A limiting plate is provided at the end of the pressure plate away from the motor output shaft to stop and fix the landing gear in the left-to-right direction.

[0018] The beneficial effects of the drone transport vehicle provided by this utility model are as follows: This utility model is an improved invention. The main difference between this utility model and the prior art is that in the prior art, the outer wings are placed horizontally and the fuselage is stored above the outer wings, resulting in a relatively high vehicle height; while in this utility model, the outer wings are placed vertically and stored on the left and right sides of the fuselage, thereby reducing the vehicle height and facilitating urban transport of drones. It should be noted that although the vehicle width is increased in this utility model, the vehicle width is still less than the lane width, meeting the needs of urban transport.

[0019] To facilitate understanding by those skilled in the art, the beneficial effects of this utility model's drone transport vehicle will be described in detail below in conjunction with the drone loading process.

[0020] During loading, the first step is to install the outer wing on the first bracket and secure it to the bracket using cable ties. The second step involves first extending the mobile platform out of the storage compartment, then using a crane to lift the fuselage onto the mobile platform (or using a hydraulic lifting trolley to lift the fuselage onto the mobile platform), securing the fuselage with cable ties or locking devices. Afterward, the mobile platform is moved back into the storage compartment. Alternatively, the mobile platform can be separated from the fixed base and placed on the ground. Then, a crane is used to lift the fuselage onto the mobile platform (or a hydraulic lifting trolley is used to lift the fuselage onto the mobile platform), securing the fuselage with cable ties or locking devices. Finally, the crane lifts the fuselage and the mobile platform (or the hydraulic lifting trolley lifts the fuselage and the mobile platform), reinstalls the mobile platform on the fixed base, and moves the mobile platform back into the storage compartment.

[0021] First, the outer wings are fixed to the first bracket. At this point, with the fuselage not obstructing the view, the workers have ample operating space. When loading the fuselage onto the vehicle, it is secured outside the vehicle, and a moving platform is used to move the fuselage into the storage compartment. Workers do not need to enter the storage compartment, making the operation convenient. Furthermore, the outer wings, located on both sides of the fuselage, help reduce the height of the drone transport vehicle.

[0022] Furthermore, the height of a truck chassis is generally between 1.3 m and 1.5 m (typically 1.4 m), while the height of a trailer chassis is generally between 0.5 m and 1 m (typically 0.9 m). The lower trailer chassis effectively reduces the height of the drone transport vehicle. When transporting drones, an SUV can be used to tow a trailer chassis. SUVs are generally between 1.7 m and 2.4 m tall, which is lower than the height of the drone transport vehicle, thus meeting height restrictions. Attached Figure Description

[0025] To address the problems in the background technology, the core inventive concept of this utility model is as follows: On the one hand, the outer wings are arranged vertically so that the width of the outer wings extends vertically, so that the height of the cargo box is used to transport the outer wings of the drone. At the same time, since the height of the drone's fuselage is greater than the width of the outer wings, the height of the cargo box will not be increased, thus effectively reducing the vehicle height. On the other hand, a trailer is selected as the vehicle, and the chassis of the trailer is lower, which can effectively reduce the vehicle height.

[0026] The present invention will be further described in detail below with reference to embodiments of the unmanned aerial vehicle transport vehicle.

[0027] In this utility model, the vehicle length direction is defined as the front-to-back direction, the vehicle width direction is defined as the left-to-right direction, and the vehicle height direction is defined as the up-to-down direction.

[0028] Reference Figures 1-2 As shown, in the first basic embodiment, the drone transport vehicle includes a chassis and a storage compartment fixed on the chassis. The rear end of the storage compartment has an openable door. A pull-out platform 2 located inside the storage compartment is connected to the chassis. The pull-out platform 2 includes a fixed base 2-3 fixed on the chassis and a movable platform 2-1 that moves horizontally with the fixed base 2-3 in the front-back direction. The movable platform 2-1 can partially extend out of the storage compartment when the compartment door is opened. The movable platform 2-1 is used in conjunction with the strapping to secure the machine body 3. The left and right side walls of the storage compartment are equipped with a first bracket for supporting the outer wings 6, which extend vertically in width, horizontally in length, and horizontally in thickness, and for cooperating with the binding straps to fix the outer wings 6.

[0029] In the second basic embodiment, the only difference from the first basic embodiment is that the moving platform 2-1 is provided with a locking device for fixing the landing gear 3-1 of the fuselage 3.

[0030] In the third basic embodiment, the only difference from the first basic embodiment is that the mobile stage 2-1 can be separated from the fixed base 2-3.

[0031] In the fourth basic embodiment, the only difference from the first basic embodiment is that the moving platform 2-1 can be separated from the fixed base 2-3, and the moving platform 2-1 is provided with a locking device for fixing the fixed landing gear 3-1 of the fuselage 3.

[0032] Based on the third and fourth basic embodiments, preferably, the bottom of the mobile platform 2-1 is provided with a pulley 2-2 for suspending the mobile platform 2-1 when it is in sliding engagement with the fixed base 2-3. After the mobile platform 2-1 is separated from the fixed base 2-3, the pulley 2-2 can be placed on the ground to facilitate the transfer of the mobile platform 2-1. When maintenance of the fuselage 3 is required, the mobile platform 2-1 can be placed on the ground without removing the fuselage 3 from its fixed position, and then maintenance can be performed directly, which facilitates the repair and maintenance of the UAV.

[0033] In the above embodiment, the storage compartment includes five sides: top, left, rear, front, and rear. The storage compartment is welded to the chassis, and the upper surface of the chassis and the storage compartment together form a space for storing the drone. One of the moving platform 2-1 and the fixed base 2-3 is provided with a slider or track extending forward and backward, and the other is provided with a sliding rail or roller extending forward and backward, so as to realize the guiding movement of the moving platform 2-1 and the fixed base 2-3. The chassis can be a truck chassis (i.e., a car chassis) or a trailer chassis 1, preferably a trailer chassis 1. The height of the truck chassis is generally between 1.3 m and 1.5 m (typical value is 1.4 m), and the height of the trailer chassis 1 is generally between 0.5 m and 1 m (typical value is 0.9 m). The trailer chassis 1 is lower, which can effectively reduce the height of the drone transport vehicle.

[0034] exist Figures 1-2 In the embodiment shown, the chassis is a trailer chassis 1, and the specifications of the drone transport vehicle are: vehicle length 7.5 m, vehicle width 2.3 m, vehicle height 3.025 m, container height 2.41 m, and chassis height 0.615 m.

[0035] When transporting drones, an SUV can be used to tow a trailer chassis. The height of an SUV is generally between 1.7 m and 2.4 m. The height of an SUV is generally lower than that of a drone transport vehicle, which can meet the height restriction requirements.

[0036] SUVs are generally 1.9 m to 2.1 m wide, while drone transport vehicles are 2.3 m wide. The width of the lanes is generally 3 m to 3.5 m, so drone transport vehicles can meet the requirements of urban road transport.

[0037] The height limit for elevated bridges and interchanges is generally between 2.8 m and 3.6 m. The height of the drone transport vehicle is 3.025 m, which allows it to pass through some elevated bridges and interchanges, making it easier to plan transport routes and benefiting urban transportation.

[0038] In one embodiment, when a 1.4 m high truck chassis is used as the chassis for the drone transport vehicle, the drone transport vehicle is 3.81 m high. Although this does not exceed the height limit standard for trucks (4.2 m), the drone transport vehicle cannot pass through most of the roads under overpasses and interchanges.

[0039] If the outer wing 6 is positioned below the drone transport vehicle as in the prior art, the height of the drone transport vehicle would reach about 4 m. In this embodiment, it is reduced to 3.025 m (or 3.81 m), which is beneficial for the drone transport vehicle to pass through roads with height restrictions between 3.025 m and 4 m (or 3.81 m and 4 m), and also beneficial for the transportation of drones.

[0040] Furthermore, when using trailer chassis 1 as the chassis for the drone transport vehicle, the drone transport vehicle does not have equipment such as a driver's cab and engine, resulting in lower costs. Workers can tow the drone transport vehicle using existing SUVs. On the one hand, there is no need to obtain a separate driver's license required for driving a truck, thus saving on the need for specialized truck drivers and reducing labor costs. On the other hand, SUVs can be used for other purposes when not transporting drones, which helps to save on vehicle costs.

[0041] The above embodiments are applicable to unmanned aerial vehicles (UAVs) that only have outer wings 6.

[0042] like Figures 1-2 As shown, when the UAV has a compound wing, the UAV includes a fuselage 3, a central wing 13, an outer wing 6, an inner arm 4, an outer arm 5, and a vertical wing 9. Among them, the central wing 13 is 3080 mm long, the outer wing 6 is 3155 mm long, and the wingspan of the UAV is 9 m.

[0043] The following describes the fixing methods for components other than wing 6.

[0044] In one embodiment, such as Figures 1-2 As shown, the left and right side walls of the storage compartment are equipped with second brackets for supporting the extended arms and for cooperating with straps to secure the arms. The arms include an inner arm 4 and an outer arm 5.

[0045] Preferably, such as Figures 1-2 As shown, the second bracket is located above the first bracket. On one hand, the outer wing 6 is relatively large, while the fuselage arm is relatively small; placing the first bracket below facilitates the placement of the outer wing 6. On the other hand, as... Figure 2 As shown, the thickness of the outer wing 6 (in the left-right direction) is smaller than that of the arm (in the left-right direction). Under the premise of avoiding interference between the outer wing 6 (first bracket) and the fuselage 3, the outer wing 6 (first bracket) can extend below the moving platform 2-1, which is conducive to further reducing the height of the storage compartment. At this time, the height of the storage compartment is determined by the height of the fuselage 3, rather than by the height occupied by the outer wing 6 and the arm in the vertical direction.

[0046] In one embodiment, such as Figure 2 As shown, the moving platform 2-1 is also used to support the central wing 13 located between the fixed landing gear 3-1 and to cooperate with the straps to fix the central wing 13. The length direction of the central wing 13 is the front-to-back direction in order to make the most of the space in the storage compartment.

[0047] exist Figures 1-2 In the embodiment shown, the first bracket includes a tray, one of the left and right sides of the tray is fixedly connected to the corresponding side wall of the storage compartment, and the other side is provided with a groove for horizontally placing the outer wing 6. The lower wall of the groove is provided with a first receiving groove for accommodating the lower part of the outer wing 6.

[0048] like Figures 1-2 As shown, the left and right width of the first bracket is smaller than that of the second bracket, so as to avoid interference between the first bracket and the fuselage 3 without increasing the width of the carriage.

[0049] Taking the left support plate as an example, when fixing the outer wing 6, the outer wing 6 is placed into the groove from right to left, and the lower end of the outer wing 6 is lowered into the first receiving groove. The groove wall of the first receiving groove is used to limit the position of the outer wing 6. To facilitate the fixing of the binding strap, perforations for the binding strap to pass through can also be provided on the support plate.

[0050] exist Figures 1-2 In the embodiment shown, the second bracket includes an L-shaped plate with a second receiving groove for accommodating the lower part of the arm; the L-shaped plate includes a horizontally arranged support plate and a vertically arranged upright plate.

[0051] Taking the left L-shaped plate as an example, when fixing the machine arm, simply place the machine arm into the second receiving slot from top to bottom and secure it with cable ties. To facilitate securing the cable ties, perforations for the cable ties to pass through can also be provided on the L-shaped plate.

[0052] Each bracket 12 can be directly welded to the side wall of the storage compartment, or it can be fixedly connected to the side wall of the storage compartment by bolts.

[0053] In other embodiments, each bracket 12 may also be composed of multiple L-shaped support rods, each L-shaped support rod including horizontal bars extending to the left and right and vertical bars extending to the top and bottom. The two ends of the horizontal bars are connected to the side wall of the storage compartment and the vertical bars, respectively. The space between the vertical bars and the corresponding side wall of the storage compartment forms a receiving space for accommodating the outer wing 6 or the arm.

[0054] In other embodiments, the left and right widths of the first bracket can be equal to those of the second bracket. In this case, the width of the storage compartment (drone transport vehicle) needs to be increased to 2.4 m. Although the drone transport vehicle is wider, it can still travel normally within a lane of 3 m to 3.5 m.

[0055] exist Figures 1-2 In the embodiment shown, the storage compartment is divided into a main storage compartment 7 for storing the fuselage 3, outer wings 6 and arms, a secondary storage compartment 8 for storing the vertical wing 9, and an accessory compartment 10 for storing the UAV's accessories 11. The secondary storage compartment 8 is located directly above the accessory compartment 10, and the main storage compartment 7 is located behind the secondary storage compartment 8 and the accessory compartment 10, so that the vertical wing 9 and the accessories 11 can be stored separately. The structure is simple.

[0056] Preferably, such as Figure 1 As shown, the auxiliary storage compartment 8 is also equipped with a bracket, and workers use cable ties to fix the vertical wing 9 to the bracket.

[0057] exist Figures 1-2 In the embodiment shown, the locking device includes a stop bar 2-4 (including a front stop bar and a rear stop bar) and a pressure plate 2-5 (including a left pressure plate and a right pressure plate) disposed on the moving platform 2-1. The distance between the front stop bar and the rear stop bar is adapted to match the front and rear length of the fixed landing gear 3-1 to limit the front and rear position of the fixed landing gear 3-1. Each pressure plate 2-5 is equipped with a motor for driving the pressure plate 2-5 to rotate. The output shaft of the motor is connected to the left or right end of the pressure plate 2-5 to press the pressure plate 2-5 to fix the landing gear 3-1. The end of the pressure plate away from the motor output shaft is provided with a limiting plate for stopping and fixing the landing gear 3-1 in the left and right direction.

[0058] In other embodiments, the locking device may also be the same as the locking device in Chinese invention patent with authorization publication number CN116620600B and authorization publication date of 2025.05.06.

[0059] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some technical features, or organically combine different embodiments to create the embodiments shown in the accompanying drawings.
