Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) take-off and landing technology, and in particular to a UAV nest transfer device and a UAV nest transfer system. Background Technology

[0002] Unmanned aerial vehicle (UAV) nests are core ground facilities supporting UAVs' automatic take-off and landing, charging, data interaction, and mission management. They have been widely applied in various scenarios such as power line inspection, emergency rescue, agricultural plant protection, and logistics transportation. Existing fixed nests are mostly deployed at designated locations and require separate construction of supporting take-off and landing platforms, power facilities, and communication links, thus generally facing practical challenges such as time-consuming construction, large investment, and limited effective service range. To improve equipment utilization and mission response speed, UAV nests are fixed on mobile vehicles (such as pickup trucks and vans). Through the movement of these mobile vehicles, a single UAV nest can be cyclically shared and reused across multiple sites.

[0003] In the above methods, ground flatness, installation accuracy, and tire pressure of pickup trucks can all affect the flatness of the drone nest, resulting in low placement efficiency of the drone nest and consequently affecting the overall work efficiency.

[0004] Therefore, it is urgent to study a nest transfer device and nest transfer system to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a nest transfer device and nest transfer system to solve the problem that the flatness of the drone nest in the prior art is poor, which makes the take-off and landing reliability of the drone low.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A nest transfer device, comprising:

[0008] An adjustment platform is available for mounting on a mobile vehicle. The adjustment platform includes an adjustment bracket and an adjustment component. The adjustment component is located on the adjustment bracket and is used to support the UAV nest.

[0009] A fixed platform is pre-installed at the work site. The adjusting bracket moves under the drive of the mobile vehicle so that the adjusting component can dock with the fixed platform, so that the adjusting component and the fixed platform are connected as one unit.

[0010] The transfer vehicle has an output end that can switch between a lifting position and a landing position. When the output end of the transfer vehicle is in the lifting position, it can carry the drone nest. The transfer vehicle can reciprocate between the integrated adjusting component and the fixed platform to place the drone nest on the adjusting component or the fixed platform.

[0011] As an optional technical solution for a machine nest transfer device, the adjustment platform further includes a suspension bridge, which is disposed on the adjustment member and can switch between a shielded position and an overlapping position. When in the overlapping position, at least a portion of the suspension bridge is located between the adjustment member and the fixed platform to cover the gap between the adjustment member and the fixed platform. The transfer vehicle passes over the suspension bridge at the overlapping position during its movement between the adjustment member and the fixed platform.

[0012] As an optional technical solution for a machine nest transfer device, the adjusting component is provided with a first receiving groove, and the first receiving groove has a first receiving opening on the side facing the fixed platform.

The drone nest transfer device also includes a docking base, on which the drone nest is installed. The docking base has a positioning hole, and the positioning pin can be inserted into the positioning hole.

[0019] As an optional technical solution for a machine nest transfer device, the transfer vehicle further includes a vehicle body, two sets of drive wheels and two power components. The two sets of drive wheels are arranged at intervals along a first direction on the vehicle body, and the two drive wheels in the same set are arranged at intervals along a second direction.

[0020] As an optional technical solution for a machine nest transfer device, the adjustment platform further includes a height adjustment component, which is disposed on the adjustment platform and whose output end can abut against a mobile vehicle to adjust the height of the adjustment platform.

[0021] As an optional technical solution for a machine nest transfer device, the height adjustment assembly includes several height adjustment seats and several height adjustment screws. The several height adjustment seats are distributed on the adjustment bracket. The height adjustment seats have adjustment screw holes. The several height adjustment screws are threaded into the several adjustment screw holes one by one, and the lower end of the height adjustment screw can abut against the mobile carrier.

[0022] As an optional technical solution for a machine nest transfer device, the height adjustment assembly further includes a height limiting member and a height limiting screw. The height limiting member can be connected to the mobile carrier. The height limiting member has a limiting elongated hole extending in a third direction. The height limiting screw passes through the limiting elongated hole and is screwed into the limiting screw hole of the adjustment bracket.

[0023] As an optional technical solution for a nest transfer device, the adjustment platform further includes a transfer bracket. The adjustment platform and the fixed platform are arranged at intervals along a first direction. The transfer bracket is movably mounted on the adjustment bracket along a second direction. The adjustment component is rotatably mounted on the transfer bracket around a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0028] As an optional technical solution for a nest transfer device, the adjustment platform further includes an overlapping component, one end of which is disposed on the adjustment member, and the other end of which can be connected to the fixed platform so that the adjustment member and the fixed platform are relatively fixed.

[0029] A nest transfer system includes a nest transfer device, a mobile vehicle, and a mobile limiting component as described in any of the above technical solutions. The mobile limiting component is pre-installed at the work site and is arranged at intervals from the fixed platform. The mobile vehicle is a pickup truck. When the pickup truck approaches the fixed platform, the tires of the pickup truck abut against the mobile limiting component.

[0030] The present invention has at least the following beneficial effects:

[0031] This invention provides a drone nest transfer device and system. The drone nest transfer device includes an adjustment platform, a fixed platform, and a transfer vehicle. The adjustment platform can be installed on a mobile vehicle and includes an adjustment bracket and an adjustment component. The adjustment component is located on the adjustment bracket and is used to support the drone nest. The fixed platform is pre-installed at the work site. The adjustment bracket moves under the drive of the mobile vehicle to allow the adjustment component to dock with the fixed platform, thus connecting the adjustment component and the fixed platform as a whole. The output end of the transfer vehicle can switch between a lifting position and a lowering position. When the output end of the transfer vehicle is in the lifting position, it can support the drone nest. The transfer vehicle can reciprocate on the integrated adjustment component and fixed platform to place the drone nest on the adjustment component or the fixed platform.

[0032] By pre-installing a fixed platform at the work site, and then transferring the adjustment platform to the vicinity of the fixed platform via a mobile vehicle, the adjustment component and the fixed platform are connected as one unit. Then, by switching between the lifting and landing positions at the output end of the transfer vehicle, the drone nest on the adjustment component is transferred to the fixed platform. Because the fixed platform has a high degree of flatness and is not affected by the tire pressure of the mobile vehicle or the installation accuracy between the adjustment platform and the mobile vehicle, the flatness of the drone nest is guaranteed, thereby ensuring the reliability of the drone's takeoff and landing.

[0055] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0056] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0057] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0058] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0059] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0060] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0061] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0062] like Figures 1 to 13As shown, this embodiment provides a drone nest transfer device, which includes an adjustment platform 100, a fixed platform 200, and a transfer vehicle 300. The adjustment platform 100 can be installed on a mobile vehicle 400. The adjustment platform 100 includes an adjustment bracket 110 and an adjustment component 120, which is disposed on the adjustment bracket 110 and used to support the drone nest 1000. The fixed platform 200 is pre-installed at the work site, and the adjustment bracket 110 is driven by the mobile vehicle 400. The downward movement allows the adjusting component 120 to dock with the fixed platform 200, and enables the adjusting component 120 and the fixed platform 200 to be connected as one unit; the output end of the transfer vehicle 300 can switch between the lifting position and the lowering position. When the output end of the transfer vehicle 300 is in the lifting position, it can carry the UAV nest 1000. The transfer vehicle 300 can move back and forth on the integrated adjusting component 120 and the fixed platform 200 to place the UAV nest 1000 on the adjusting component 120 or the fixed platform 200.

[0063] By pre-installing a fixed platform 200 at the work site, and transferring the adjustment platform 100 to the vicinity of the fixed platform 200 via a mobile carrier 400, the adjustment component 120 and the fixed platform 200 are connected as one unit. Then, by switching between the lifting and landing positions at the output end of the transfer vehicle 300, the UAV nest 1000 on the adjustment component 120 is transferred to the fixed platform 200. Because the fixed platform 200 has a high degree of flatness and is not affected by the tire pressure of the mobile carrier 400 or the installation accuracy between the adjustment platform 100 and the mobile carrier 400, the flatness of the UAV nest 1000 is guaranteed, thereby ensuring the reliability of UAV takeoff and landing.

[0064] In other embodiments, when the adjusting component 120 is docked with the fixed platform 200, the adjusting platform 100 can be placed either on the mobile vehicle 400 or at the work site, and can be spaced apart from the fixed platform 200 so that the adjusting component 120 and the fixed platform 200 are integrated. The mobile vehicle 400 can be a pickup truck or a van.

[0065] In some embodiments, the transfer vehicle 300 includes a vehicle body 310, a lifting drive assembly 320, and a carrier 330. The carrier 330 is located on top of the vehicle body 310 and can move between a lifted position and a lowered position. The lifting drive assembly 320 is located on the vehicle body 310 and is throttle-connected to the carrier 330. By driving the carrier 330 with the lifting drive assembly 320, the level of automation and the transfer efficiency of the UAV nest 1000 are improved.

[0066] To ensure the trajectory of the lifting and lowering of the support component 330, the support component 330 includes a support plate 331 and a support guide component 332 located below the support plate 331. The vehicle body 310 is provided with a support guide channel, the support plate 331 is located above the vehicle body 310, and the support guide component 332 passes through the support guide channel. The above arrangement ensures that the movement trajectory of the support plate 331 is fixed and will not deflect, thus ensuring the stability of supporting the UAV nest 1000.

[0067] The lifting drive assembly 320 includes a rotary drive component 321, a lifting screw 322, and a lifting nut. The rotary drive component 321 is mounted on the vehicle body 310. The lifting screw 322 and the lifting nut are threaded together. One of the lifting screw 322 and the lifting nut is connected to the rotary drive component 321, and the other is connected to the support plate 331. Specifically, the lifting nut is rotatably mounted on the vehicle body 310 and is connected to the output end of the rotary drive component 321. The lifting screw 322 is connected to the support plate 331. A gear is connected to the output end of the rotary drive component 321, and teeth that mesh with the gear are provided on the outer side of the lifting nut.

[0068] To ensure the force balance of the UAV nest 1000, in some embodiments, the support member 330 includes two support guide members 332, and the lifting screw 322 is located between the two support guide members 332. The above arrangement ensures the force balance of the support plate 331, guarantees the stability of lifting and lowering, avoids jamming, and thus ensures more stable support for the UAV nest 1000.

[0069] In some embodiments, the transfer vehicle 300 includes two carrier members 330 and two lifting drive assemblies 320, with each of the two lifting drive assemblies 320 corresponding to one of the two carrier members 330. The carrier members 330 are elongated and extend along a second direction, and the two carrier members 330 are spaced apart along a first direction. This arrangement helps to reduce the bearing area of ​​a single carrier member 330 and helps to adapt to the uneven structure at the bottom of the UAV nest 1000.

[0070] To prevent the UAV nest 1000 from slipping off during the movement of the transport vehicle 300, in some embodiments, the carrier 330 further includes a positioning pin 333 extending in a third direction. The positioning pin 333 is located on the upper side of the carrier plate 331. The nest transfer device also includes a docking base 1100, on which the UAV nest 1000 is mounted. The docking base 1100 has positioning holes into which the positioning pin 333 can be inserted. The positioning pin 333 extends in a vertical direction. The above arrangement achieves relative fixation between the UAV nest 1000 and the carrier plate 331 in the horizontal direction, thereby preventing the UAV nest 1000 from slipping off the carrier plate 331 due to inertia at the moment the transport vehicle 300 starts and stops.

[0071] To ensure the smooth operation of the transfer vehicle 300, in some embodiments, the transfer vehicle 300 further includes a vehicle body 310, two sets of drive wheels 340, and two power units 350. The two sets of drive wheels 340 are spaced apart on the vehicle body 310 along a first direction, and the two drive wheels 340 in the same set are spaced apart on the vehicle body 310 along a second direction. The two power units 350 correspond one-to-one with the two sets of drive wheels 340, and each power unit 350 simultaneously drives the two drive wheels 340 in its corresponding set. This four-wheel drive system improves the passability of the transfer vehicle 300, thereby ensuring the smooth transfer of the transfer vehicle 300 between the adjusting component 120 and the fixed platform 200.

[0072] To ensure that the height of the adjusting component 120 and the fixed platform 200 are consistent and to avoid significant obstacles during the movement of the transfer vehicle 300, in some embodiments, the adjusting platform 100 also includes a height adjustment component. This height adjustment component is located on the adjusting platform 100, and its output end can abut against the mobile carrier 400 to adjust the height of the adjusting platform 100. This ensures that when the adjusting component 120 and the fixed platform 200 are integrated, they are relatively flat, facilitating the smooth transfer of the transfer vehicle 300. Alternatively, the output end of the height adjustment component can also abut against the ground at the work site.

[0073] Specifically, the height adjustment assembly includes several height adjustment seats 113 and several height adjustment screws 114. The height adjustment seats 113 are distributed on the adjustment bracket 110, and each height adjustment seat 113 has an adjustment screw hole. The several height adjustment screws 114 are threaded into the several adjustment screw holes one-to-one, and the lower end of the height adjustment screw 114 can abut against the moving carrier 400. By adjusting the multiple height adjustment screws 114, the overall height and levelness of the adjustment bracket 110 can be adjusted. The lower end of each height adjustment screw 114 has a support foot. The cross-sectional area of ​​the support foot is larger than the cross-sectional area of ​​the height adjustment screw 114.

[0074] When the adjustment platform 100 is placed on the pickup truck, to prevent it from shaking, the adjustment bracket 110 is separated from the pickup truck. The height adjustment assembly also includes a height limiting member 115 and a height limiting screw. The height limiting member 115 can be connected to the mobile vehicle 400. The height limiting member 115 has a limiting elongated hole 116 extending in a third direction. The height limiting screw passes through the limiting elongated hole 116 and is screwed into the limiting screw hole of the adjustment bracket 110. The above configuration can connect the adjustment bracket 110 and the pickup truck as one unit.

[0075] The adjustment platform 100 also includes a transfer bracket 130. The adjustment platform 100 and the fixed platform 200 are arranged at intervals along a first direction. The transfer bracket 130 is movably mounted on the adjustment bracket 110 along a second direction. The adjustment component 120 is rotatably mounted on the transfer bracket 130 around a third direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0076] The first direction is the front-back direction, the second direction is the left-right direction, and the third direction is the up-down direction.

[0077] By movably mounting the adjusting component 120 on the adjusting bracket 110 in two directions, when the mobile carrier 400 approaches the fixed platform 200, even if there is a slight deviation, the adjusting component 120 can be moved relative to the adjusting bracket 110 to connect with the fixed platform 200. This facilitates the transfer vehicle 300 to smoothly transfer the drone nest 1000 from the mobile carrier 400 to the fixed platform 200, and vice versa. This avoids repeated adjustments to the position of the mobile carrier 400, thereby improving the transfer efficiency of the drone nest 1000 and ensuring the overall efficiency of subsequent work.

[0078] Specifically, the adjusting bracket 110 is equipped with an adjusting slide rail 111 extending along a second direction, and the adjusting slide rail 111 is slidably mounted with adjusting sliders 112. The transfer bracket 130 is connected to the adjusting sliders 112. The adjusting bracket 110 has two adjusting slide rails 111 spaced apart along a first direction, and each adjusting slide rail 111 has at least two adjusting sliders 112. In other embodiments, the transfer bracket 130 and the adjusting bracket 110 can slide relative to each other via sliding grooves and sliding protrusions.

[0079] Regarding the connection method between the adjusting component 120 and the transfer bracket 130, in some embodiments, the adjusting component 120 includes an adjusting body 121 and a rotating shaft 122 and a sliding shaft 123 disposed on the adjusting body 121. The transfer bracket 130 is provided with a rotating hole 132 and an arc-shaped sliding groove 131. The sliding groove 131 and the rotating hole 132 are arranged concentrically. The rotating shaft 122 is rotatably disposed in the rotating hole 132, and the sliding shaft 123 passes through the sliding groove 131 and can slide around the axis of the rotating shaft 122 in the sliding groove 131. The above-mentioned structure is simple and easy to manufacture; the cooperation of the sliding groove 131 and the sliding shaft 123 helps to limit the rotation angle of the adjusting component 120. Part of the adjusting component 120 is located between the two tire clearance sections 420 of the pickup truck. The rotating hole 132 is located on the side of the sliding groove 131 away from the fixed platform 200. The above configuration results in a smaller swing range at the end of the adjusting component 120 that is away from the fixed platform 200, thus avoiding interference with the tire clearance section 420 inside the pickup truck.

[0080] In some embodiments, the adjustment platform 100 further includes a first locking member 141, a second locking member 142, and a third locking member 143. The first locking member 141 is disposed on the adjustment bracket 110, the second locking member 142 is disposed on the transfer bracket 130, and the third locking member 143 is disposed on the adjustment member 120. The first locking member 141, the second locking member 142, and the third locking member 143 can be locked and fixed by the locking members. The above arrangement helps to ensure that the adjustment member 120, the transfer bracket 130, and the adjustment bracket 110 do not move relative to each other during the movement of the mobile carrier 400, avoids shaking of the UAV nest 1000, avoids collisions, and ensures reliability in use.

[0081] Specifically, the first locking member 141 has a first locking hole, the second locking member 142 has a second locking hole, and the third locking member 143 has a third locking hole 144. The locking members are pins, which pass through the third locking hole 144, the second locking hole, and the first locking hole to lock the first locking member 141, the second locking member 142, and the third locking member 143 together. This pin-based locking method simplifies the locking process and facilitates operation. In other embodiments, the locking member is a screw, the first locking hole is a screw hole, and the screw is screwed into the screw hole.

[0082] Even when the pickup truck is stationary, the vehicle body may sway due to workers getting in and out, and loading and unloading workpieces. This causes the adjusting component 120 to move, resulting in relative movement between it and the fixed platform 200, affecting the smooth operation of the transfer vehicle 300. To address this issue, in some embodiments, the adjusting platform 100 further includes an overlapping component 150. One end of the overlapping component 150 is attached to the adjusting component 120, and the other end can connect to the fixed platform 200, thus fixing the adjusting component 120 and the fixed platform 200 relatively securely. This arrangement helps ensure the smooth movement of the transfer vehicle 300 and the uniqueness of its movement path.

[0083] Specifically, the adjustment platform 100 also includes a locking assembly, and the overlapping assembly 150 includes an overlapping rod 151, which is connected to the adjusting member 120. The overlapping rod 151 is connected to the fixed platform 200 through the locking assembly. By locking, even if the pickup truck experiences relative swaying, only the adjusting bracket 110 can move. Since the adjusting bracket 110 and the adjusting member 120 can move relative to each other, the adjusting member 120 and the fixed platform 200 can be kept relatively stationary, thereby ensuring the driving stability of the transfer vehicle 300.

[0084] For example, the connecting rod 151 is slidably disposed on the adjusting member 120 along a first direction and switches between a retracted position and an extended position. When the connecting rod 151 is in the retracted position, its vertical projection is located on the pickup truck. When the connecting rod 151 is in the extended position, its vertical projection is located outside the pickup truck. The portion of the connecting rod 151 located outside the pickup truck is connected to the fixed platform 200. When the connecting rod 151 is in the retracted position, the total length of the pickup truck and the connecting rod 151 is smaller, facilitating the driving of the pickup truck. In addition, when the connecting rod 151 is in the extended position, the adjusting member 120 can be driven to move relative to the adjusting bracket 110 by operating the end of the connecting rod 151 away from the adjusting member 120, thereby increasing the lever arm and making the adjustment of the adjusting member 120 easier.

[0085] Specifically, the fixed platform 200 includes a platform body 210 and a fixed seat 220 disposed on the platform body 210, the fixed seat 220 having a fixing hole; the locking assembly includes a locking seat 152, a locking pull rod 153, and a locking drive member 154, the overlapping rod 151 is clamped between the locking seat 152 and the fixed seat 220, one end of the locking pull rod 153 has a locking connector 1531, the locking seat 152 has a locking hole, the locking pull rod 153 passes through the locking hole and the fixing hole, the locking drive member 154 is disposed on the locking seat 152, and its output end is connected to the locking pull rod 153 to drive the locking pull rod 153 to move and cause the locking seat 152 and the fixed seat 220 to clamp the overlapping rod 151. The above arrangement realizes the connection between the fixed platform 200 and the overlapping rod 151, thereby realizing the relative fixed connection between the fixed platform 200 and the adjusting member 120. The fixing hole is elongated and includes a widened part and a fixing part. The width of the widened part is greater than that of the locking joint 1531, and the width of the fixing part is less than that of the locking joint 1531 but greater than that of the locking pull rod 153.

[0086] It should be noted that the locking drive component 154 is an elbow clamp. The output end of the elbow clamp is connected to the end of the locking pull rod 153 away from the locking connector 1531. The elbow clamp can realize the push-pull action of the locking pull rod 153 and has a self-locking function to ensure the reliability of the locking. In addition, the locking drive component 154 can be a locking nut. The locking nut is threaded with the locking pull rod 153. Tightening the locking nut will cause the locking seat 152 and the fixing seat 220 to clamp the overlapping rod 151.

[0087] To ensure reliable connection, two sets of overlapping rods 151 are provided, with the two sets of overlapping rods 151 respectively arranged on both sides of the fixed platform 200 along the second direction. Each set has at least two overlapping rods 151, and the at least two overlapping rods 151 in the same set are spaced apart along the third direction. The locking hole is located between two adjacent overlapping rods 151. The above arrangement improves the stress stability between the locking seat 152 and the fixed seat 220, ensuring reliable locking.

[0088] Furthermore, the locking seat 152 has a locking groove 1521, into which the overlapping rod 151 is engaged. This design improves the ease of engagement, helps prevent the overlapping rod 151 from separating from the locking seat 152, and further enhances the reliability of the locking mechanism. The locking groove 1521 is a V-shaped groove to facilitate the engagement of cylindrical overlapping rods 151 and can accommodate overlapping rods 151 of different diameters.

[0089] In some embodiments, the fixed platform 200 includes four pads 230, which are disposed on the platform body 210. Two pads 230 in each group are disposed on both sides of the fixing seat 220 along a first direction, and the pads 230 protrude from the fixing seat 220. The overlapping rod 151 abuts against the two pads 230. The above arrangement makes the force on the overlapping rod 151 distributed in a three-point manner, and under the action of the locking rod 153, the point of application of the force applied by the locking seat 152 to the overlapping rod 151 is located between the two pads 230, so that the overlapping rod 151 is firmly fixed to the platform body 210. The pads 230 are made of rubber or metal.

[0090] An overlap seat 157 is mounted on the adjusting member 120. The overlap seat 157 has a sliding channel, in which the overlap rod 151 is slidably disposed. The sliding channel extends along a first direction. In some embodiments, each overlap rod 151 is provided with two overlap seats 157. The two overlap seats 157 corresponding to the same overlap rod 151 are arranged at intervals along the first direction.

[0091] The overlapping assembly 150 includes overlapping limit members 155. One of the two overlapping limit members 155 is located at one end of the two overlapping rods 151 in the same group and connects to the two overlapping rods 151. The other of the two overlapping limit members 155 is located at the other end of the two overlapping rods 151 in the same group and connects to the two overlapping rods 151. The overlapping rods 151 and the overlapping limit members 155 form a rectangular structure. The overlapping limit members 155 help prevent the overlapping rods 151 from being pulled out of the sliding channel. In other embodiments, the overlapping limit members 155 near the fixed platform 200 can be held to pull out the overlapping rods 151 and adjust the position of the adjusting member 120. For ease of gripping, a handle 156 is installed on the overlapping limit members 155 near the fixed platform 200. In use, after the pickup truck has come to a complete stop, first pull out the connecting rod 151 using the left handle 156, then place the connecting rod 151 against the left pad 230 and lock it using the locking assembly; then pull out the connecting rod 151 using the right handle 156, place it against the right pad 230, and lock it using another locking assembly. The left and right order can be adjusted.

[0092] To prevent collisions between the pickup truck and the fixed platform 200 when the pickup truck approaches, the distance between them can be appropriately increased, leaving a gap between them when the pickup truck is stationary. Furthermore, to ensure smooth movement of the transfer vehicle 300 between the adjusting member 120 and the fixed platform 200, in some embodiments, the adjusting platform 100 further includes a suspension bridge 500. The suspension bridge 500 is located on the adjusting member 120 and can switch between an obstructed position and an overlapping position. When in the overlapping position, at least a portion of the suspension bridge 500 is located between the adjusting member 120 and the fixed platform 200 to cover the gap between them. This arrangement allows the suspension bridge 500 to be switched to the overlapping position after the pickup truck has come to a complete stop, connecting the adjusting member 120 and the fixed platform 200, enabling the transfer vehicle 300 to move smoothly back and forth between the adjusting member 120 and the fixed platform 200.

[0093] The adjusting component 120 is provided with a first receiving groove 124. The first receiving groove 124 has a first receiving opening on the side facing the fixed platform 200. The first receiving groove 124 is used to receive the transfer vehicle 300. When the suspension bridge 500 is in the obstructed position, it blocks the first receiving opening. When the suspension bridge 500 is in the obstructed position, it extends vertically. When the suspension bridge 500 is in the overlapping position, it extends horizontally. The above arrangement can limit the movement of the transfer vehicle 300, preventing it from shaking or even falling off the adjusting component 120 during the pickup truck's operation. On the other hand, the suspension bridge 500 in the obstructed position can reduce the area occupied by the pickup truck. In addition, when the suspension bridge 500 is in the obstructed position, it can also abut against the rear end of the UAV nest 1000 placed on the adjusting component 120.

[0094] The first receiving groove 124 has a second receiving opening on its upper side. The drone nest 1000 is placed on the adjusting component 120. The transfer vehicle 300 can lift the drone nest 1000 in the first receiving groove 124 through the second receiving opening. During the movement of the transfer vehicle 300, the drone nest 1000 is moved.

[0095] Regarding the installation method of the suspension bridge 500, in some embodiments, the suspension bridge 500 is hinged to the adjusting member 120. The adjusting platform 100 also includes a first elastic member 510, one end of which is located on the adjusting member 120 and the other end on the suspension bridge 500. The suspension bridge 500 passes through an intermediate position during the process of switching from the obstructed position to the overlapping position. When the suspension bridge 500 is in the intermediate position, the length of the first elastic member 510 is at its maximum. The above arrangement helps to lock the suspension bridge 500 in two positions, that is, under the action of the first elastic member 510, the suspension bridge 500 can be maintained in either the obstructed or overlapping position. When switching, the suspension bridge 500 can be driven manually or automatically. One end of the first elastic member 510 is connected to the adjusting member 120, and the other end is connected to the suspension bridge 500. The hinge point of the suspension bridge 500 is located at the lower end of the adjusting member 120, so that when the suspension bridge 500 is in the overlapping position, it is flush with the bottom of the first receiving groove 124. During the switching between the two positions of the suspension bridge 500, the center of rotation of the suspension bridge 500 will cross the axis of the first elastic element 510.

[0096] For example, the first elastic element 510 is a gas spring, with one end hinged to the adjusting member 120 and the other end hinged to the suspension bridge 500. The gas spring has a nearly constant force curve, with minimal change in support force across most of its stroke, offering excellent controllability. Advanced functions such as tension damping, compression damping, locking, and positioning can be achieved through internal valve design. It offers flexible installation, typically with hinged joints at both ends, and can withstand a certain radial force. It occupies a relatively compact space and provides a large force. In other embodiments, the first elastic element 510 can be a tension spring.

[0097] To ensure the docking accuracy of the suspension bridge 500 and the fixed platform 200, in some embodiments, one of the fixed platform 200 and the suspension bridge 500 is provided with a docking groove 211 and the other is provided with a docking protrusion. When the suspension bridge 500 is in the overlapping position, the docking protrusion is inserted into the docking groove 211.

[0098] For example, the fixed platform 200 has two abutment grooves 211 spaced apart along a second direction and both extending along a first direction. The suspension bridge 500 includes a flat bridge body 520 with two reinforcing ribs 530 spaced apart along the second direction on the bridge body 520. The reinforcing ribs 530 extend along the first direction and form abutment protrusions. The aforementioned reinforcing ribs 530, on the one hand, increase the structural strength of the suspension bridge 500 and prevent collapse; on the other hand, as an insertion structure with the abutment grooves 211, they ensure the relative positional relationship between the suspension bridge 500 and the fixed platform 200 and prevent relative displacement.

[0099] The adjusting component 120 is provided with a first anti-slip portion 125, along which the transport vehicle 300 travels to prevent slippage. Exemplarily, the adjusting body 121 has a plurality of anti-slip holes spaced apart along a first direction to form the first anti-slip portion 125. The arrangement of the anti-slip holes serves several purposes: firstly, it cooperates with protrusions on the tires of the transport vehicle 300 to prevent slippage; secondly, it reduces the weight of the adjusting component 120, lowering costs; and thirdly, it helps dirt on the tires of the transport vehicle 300 to fall through the anti-slip holes, keeping the adjusting component 120 clean.

[0100] In some embodiments, the suspension bridge 500 is provided with a second anti-slip part, which has the same structure as the first anti-slip part 125. In some embodiments, the fixed platform 200 is provided with a third anti-slip part, which has the same structure as the first anti-slip part 125.

[0101] When the transport vehicle 300 places the UAV nest 1000 onto the fixed platform 200, it needs to establish both a communication and electrical connection with the fixed platform 200. To ensure the accuracy of the transport vehicle 300's docking position on the fixed platform 200, in some embodiments, the fixed platform 200 has a second receiving slot 212, with a third receiving opening on its upper side and a fourth receiving opening on the side of the second receiving slot 212 facing the adjustment platform 100; a first docking member 240 is disposed on the fixed platform 200, and the UAV nest 1000 has a second docking member 1200; when the transport vehicle 300 moves into the second receiving slot 212 to place the UAV nest 1000 onto the fixed platform 200, the second docking member 1200 engages with the first docking member 240. The second receiving slot 212 constrains the operating trajectory of the transport vehicle 300, thereby ensuring that the second docking member 1200 can smoothly and accurately dock with the first docking member 240.

[0102] The transfer carriage 300 is equipped with a detection element. When the transfer carriage 300 moves into the second receiving slot 212, the detection element sends a positioning signal, and the transfer carriage 300 stops moving. Additionally, the transfer carriage 300 is equipped with a trigger switch. When the transfer carriage 300 moves into the second receiving slot 212, the trigger switch is activated, and the transfer carriage 300 stops moving. When the transfer carriage 300 moves to the adjusting member 120, the stopping position can also be precisely determined using the detection element and the trigger switch.

[0103] The fixed platform 200 includes a platform body 210 and a protective cover 250. A first docking member 240 is disposed on the platform body 210, and the protective cover 250 is movably disposed on the platform body 210, moving between a covered position and a clearance position. When the protective cover 250 is in the covered position, the first docking member 240 is located within the protective cavity enclosed by the protective cover 250 and the platform body 210. When the protective cover 250 is in the clearance position, the second docking member 1200 can dock with the first docking member 240. This arrangement ensures that when the second docking member 1200 is not docked, the first docking member 240 is protected by the protective cover 250, preventing it from being rained on, thus improving its service life and the reliability of the connection.

[0104] In some embodiments, the protective cover 250 has a first protective groove 251 with its opening facing downwards and a second protective groove 252 with its opening facing the adjustment platform 100. A clearance notch is provided on the lower side of the second protective groove 252. When the protective cover 250 is in the covered position, the first docking member 240 is located in the first protective groove 251; when the protective cover 250 is in the clearance position, the first docking member 240 is located in the second protective groove 252. When the aforementioned fixed platform 200 is not occupied by the UAV nest 1000, the first docking member 240 is protected by the protective cover 250, preventing it from being rained on. When the first docking member 240 and the second docking member 1200 are docked, the first docking member 240 is protected by the second protective groove 252, and the opening of the second protective groove 252 facing the adjustment platform 100 is sealed by the outer shell of the UAV nest 1000, forming a relatively sealed space to prevent rain. In other embodiments, the outer shell of the UAV nest 1000 is provided with an extension plate. When the first docking member 240 and the second docking member 1200 are docked, the extension plate partially covers the protective cover 250, at least vertically covering the opening of the second protective groove 252 facing the adjustment platform 100. This arrangement protects the first docking member 240 and the second docking member 1200 while allowing a gap between the UAV nest 1000 and the protective cover 250 to prevent collisions.

[0105] The protective cover 250 has a sliding channel, and the fixed platform 200 further includes a sliding guide rod 213 along a first direction. The sliding guide rod 213 passes through the sliding channel. When the transfer vehicle 300 moves into the second receiving groove 212, it drives the second docking member 1200 to abut against the protective cover 250, causing it to slide to a clearance position. In some embodiments, a second elastic member is disposed between the protective cover 250 and the fixed platform 200, and applies an elastic force to the protective cover 250 to give it a tendency to move to the covered position. In its natural state, the protective cover 250 remains in the covered position.

[0106] This embodiment also provides a drone nest transfer system, including the drone nest transfer device and mobile vehicle 400 as described in any of the above embodiments. The mobile vehicle 400 is used to carry the adjustment platform 100 and can travel to various designated locations to transfer the drone nest 1000 to various designated locations.

[0107] The machine nest transfer system also includes a movable limiting component 410, which is pre-installed at the work site and spaced apart from the fixed platform 200. The mobile vehicle 400 is a pickup truck. When the pickup truck approaches the fixed platform 200, its tires abut against the movable limiting component 410. The abutment between the mobile vehicle 400 and the movable limiting component 410 ensures precise positioning of the mobile vehicle 400. For example, the movable limiting component 410 is elongated and designed to abut against the pickup truck's tires to restrict its continued rotation. The movable limiting component 410 can be a reinforced concrete structure or a plastic structure.

[0108] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
