Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicles (UAVs), and more particularly to central control units with replaceable core boards. Background Technology

[0002] As drones are increasingly used in security, surveying, and inspection scenarios, ground control units need to simultaneously handle the installation, power supply, and data aggregation of multiple antenna / sensor peripherals, and provide maintainable assembly space for core functions such as flight control, image transmission, and edge computing.

[0003] However, in existing central control units with circumferentially arranged connecting surfaces, the top cover / side panel and mounting box are mostly fixed to the mounting box by screws, clips, and other connectors that clamp along the axis. During maintenance, it is necessary to align and operate these connectors horizontally (e.g., by horizontally inserting a screwdriver, wrench, or clip release tool). In UAV applications, the central control unit is usually surrounded by antenna brackets, feeder clamps, and other external accessories arranged in a ring. These circumferentially positioned brackets can create physical obstructions and tool interference in the horizontal direction, making it difficult to align the connectors and to disassemble and assemble them one by one. At the same time, changing the stress and disassembly posture to avoid the brackets can easily cause wire harness pulling, fastener stripping, or seal damage, significantly prolonging maintenance time and increasing the risk of failure.

[0004] Therefore, there is a need for a central control unit that can be easily disassembled vertically. Utility Model Content

[0005] In view of this, it is necessary to provide a central control unit with a replaceable core board that is easy to disassemble from the vertical direction in order to solve the above problems.

[0006] Embodiments of this application provide a central control unit with a replaceable core board, including a load-bearing structure, an upper cover, and an equipment compartment. The upper cover is vertically disposed on the load-bearing structure, and includes a support assembly and a baffle assembly formed sequentially along the vertical direction. The support assembly and the baffle assembly have a detachably connected connecting portion, which extends radially along the central axis of the upper cover. A connector extends into the connecting portion along the vertical direction to connect the support assembly and the baffle assembly. The equipment compartment is sandwiched between the load-bearing structure and the upper cover; wherein the upper cover and the equipment compartment are spliced ​​together in opposite directions along the vertical direction to form a receiving cavity, the receiving cavity being used to accommodate the core board.

[0010] In at least one embodiment of this application, the upper cover is a multifaceted frustum-shaped shell continuously arranged in the circumferential direction, and the support assembly forms the outer inclined wall of the upper cover, and the baffle assembly forms the inner inclined wall of the upper cover.

[0011] In at least one embodiment of this application, the equipment compartment further includes a wiring platform disposed circumferentially along the equipment compartment; The cabling platform includes: A connecting rod, one end of which is located on the equipment compartment; A wiring ring plate is spaced apart from the equipment compartment, and the other end of the connecting rod is located on the wiring ring plate.

[0012] In at least one embodiment of this application, through holes are formed on the wiring ring plate at circumferential intervals for inserting antenna brackets.

[0013] In at least one embodiment of this application, the equipment compartment further includes a storage plate, which is detachably disposed in the receiving cavity to divide the receiving cavity into a first placement cavity and a second placement cavity along the vertical direction, wherein the first placement cavity is disposed on the side close to the upper cover.

[0014] In at least one embodiment of this application, the support component has a plurality of first insertion holes, which are arranged around the support component in a horizontal direction, and the first insertion holes penetrate the support component and are connected to the first placement cavity. The equipment compartment is provided with a plurality of second insertion holes, which are arranged around the equipment compartment in a horizontal direction, and the second insertion holes penetrate the equipment compartment and are connected to the second placement cavity; The first insertion hole and the second insertion hole correspond one-to-one in the vertical direction.

[0015] In at least one embodiment of this application, the load-bearing structure includes a first support leg, a second support leg, a third support leg, and a fourth support leg. The first support leg and the second support leg are arranged opposite to each other, and the third support leg and the fourth support leg are arranged opposite to each other, with the four support legs forming a rectangular arrangement.

The upper cover and the equipment compartment are vertically aligned to form a cavity for housing the core boards. During maintenance, only the vertically unlocking connector is needed to separate the two functional sections of the upper cover and directly open the cavity, avoiding tool interference with the circumferential antenna support and feeder clamps.

[0019] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0021] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] according to Figures 1-8 This application provides a central control unit 100 with a replaceable core board, including: a load-bearing structure 10, an upper cover 20, and an equipment compartment 40. The upper cover 20 is vertically mounted on the load-bearing structure 10. The upper cover 20 includes a support assembly 21 and a baffle assembly 22, which are sequentially formed vertically and have a detachably connected portion 23. The connected portion 23 extends radially along the central axis of the upper cover 20. A connector extends into the connected portion 23 along the vertical direction to connect the support assembly 21 and the baffle assembly 22. The equipment compartment 40 is sandwiched between the load-bearing structure 10 and the upper cover 20. The upper cover 20 and the equipment compartment 40 are vertically joined together to form a receiving cavity 50 for accommodating the core board.

[0023] Specifically, the load-bearing structure 10 serves as the basic load-bearing component, providing overall support and stability. The upper cover 20 is vertically mounted on the load-bearing structure 10. The upper cover 20 includes a support assembly 21 and a baffle assembly 22, which are formed sequentially in the vertical direction. The support assembly 21 typically forms the outer portion of the upper cover 20, providing structural strength and external interface support; the baffle assembly 22 forms the inner portion, sealing and protecting the internal components. It should be noted that the upper cover 20 is a prismatic structure.

[0024] Furthermore, the support assembly 21 and the baffle assembly 22 are assembled via a detachable connecting part 23. This connecting part 23 extends radially along the central axis of the upper cover 20, meaning that the connecting part 23 is arranged radially outward from the center, thus forming a circumferential connection interface. Connectors (such as screws or bolts) extend vertically into the connecting part 23 to secure the support assembly 21 and the baffle assembly 22 together. The equipment compartment 40 is sandwiched between the load-bearing structure 10 and the upper cover 20, and is vertically aligned with the upper cover 20 to form a closed receiving cavity 50 specifically for accommodating the core board. This design makes the core board easily accessible and replaceable, while avoiding circumferential interference through the vertical connection.

[0025] In one specific embodiment, the connecting portion 23 includes a first connecting end 211 and a second connecting end 221.

[0026] The first connecting end 211 is disposed on the support component 21; the second connecting end 221 is disposed on the baffle component 22, and the first connecting end 211 and the second connecting end 221 are connected together.

[0027] Specifically, the first connecting end 211 is part of the support component 21 and forms an integrated structural connection with the support component 21; the second connecting end 221 is part of the baffle component 22 and forms an integrated structural connection with the baffle component 22. The first connecting end 211 is located at the top edge of the support component 21, and the second connecting end 221 is correspondingly located at the bottom edge of the baffle component 22. When the support component 21 and the baffle component 22 are assembled vertically, the first connecting end 211 and the second connecting end 221 are radially mated and fitted together along the upper cover 20, forming a continuous connection structure.

[0028] By mating the first connecting end 211 and the second connecting end 221, a solid connection between the two is achieved using connectors. This allows the support assembly 21 and the baffle assembly 22 to fit together better during connection. At the same time, the mating fit ensures the sealing and overall rigidity of the connecting part 23, reducing the risk of external dust and moisture entering the receiving cavity 50 through the connection gaps. This ensures the stability and sealing of the overall structure of the upper cover 20, thereby providing a good protective environment for the core circuit board inside the receiving cavity 50.

[0029] In one specific embodiment, the first connecting end 211 has a first connecting hole 2112. The second connecting end 221 has a second connecting hole 2211. The first connecting hole 2112 and the second connecting hole 2211 are both connected in the vertical direction. The connector passes through the first connecting hole 2112 and the second connecting hole 2211 to fix the first connecting end 211 and the second connecting end 221.

[0030] Specifically, the first connecting hole 2112 on the first connecting end 211 and the second connecting hole 2211 on the second connecting end 221 both penetrate vertically through their respective connecting ends. When the first connecting end 211 and the second connecting end 221 are mated, the axes of the two holes are collinear, forming a vertically connected channel. Connecting components (such as bolts, screws, etc.) can penetrate the first connecting hole 2112 and the second connecting hole 2211 from top to bottom along this vertical channel, and rigidly fix the first connecting end 211 and the second connecting end 221 by threaded engagement or other fastening methods. This hole design not only clarifies the assembly path of the connecting components, but also ensures the accuracy of the mating of the first and second connecting ends 221 through the constraint of collinear hole axes, making the connection force between the support assembly 21 and the baffle assembly 22 more uniform.

[0031] Furthermore, the vertically connected connection hole provides the only vertical operating path for the connector, allowing operators to directly insert tools (such as screwdrivers or wrenches) from above or below in the vertical direction to operate the connector, completely avoiding the antenna brackets arranged around the central control unit.

[0032] The collinear design of the holes ensures that the clamping force of the connector on the first and second connecting ends 221 is transmitted in the vertical direction, avoiding local stress concentration caused by hole misalignment, improving the structural reliability of the connecting part 23, and reducing the probability of loosening of the connector and deformation of the connecting end after long-term use.

[0033] In one specific embodiment, the support component 21 further includes a third connecting end 213, which is located on the side of the support component 21 away from the first connecting end 211, and is connected to the equipment compartment 40. The first connecting end 211 is far from the central axis of the upper cover 20, and the third connecting end 213 is close to the central axis of the upper cover 20.

[0034] Specifically, the third connecting end 213 is located on the support assembly 21 on the side away from the first connecting end 211. Specifically, the first connecting end 211 is located on the outer edge of the support assembly 21, and its function is to mate with the baffle assembly 22, with the first connecting end 211 located away from the central axis of the upper cover 20; while the third connecting end 213 is located on the inner edge of the support assembly 21, and its position is closer to the central axis of the upper cover 20. The function of this third connecting end 213 is to connect with the equipment compartment 40, thereby establishing an independent fixing point between the support assembly 21 and the equipment compartment 40.

[0035] In this embodiment, the third connecting end 213 and the equipment compartment 40 can be an integral structure or formed by welding and fixing. The support component 21 is locked to the baffle component 22 through its outer first connecting end 211, and is also connected to the equipment compartment 40 through its inner third connecting end 213. When it is necessary to replace the core board in the receiving cavity 50, it is only necessary to disconnect the connection between the first connecting end 211 and the second connecting end 221 in the connecting part 23 to expose the receiving cavity 50, thereby enabling operation within the receiving cavity 50.

[0036] In one specific embodiment, the upper cover 20 is a multi-faceted frustum-shaped shell continuously arranged in the circumferential direction, and the support assembly 21 forms the outer inclined wall of the upper cover 20, and the baffle assembly 22 forms the inner inclined wall of the upper cover 20.

[0037] Specifically, the upper cover 20 adopts a multi-faceted frustum-shaped shell structure that is continuously closed along the circumference. Its overall shape presents a frustum shape that is narrower at the top and wider at the bottom. The upper cover 20 is a frustum structure composed of multiple continuously spliced ​​inclined surfaces, with the cross-section gradually increasing or decreasing from top to bottom. Moreover, this frustum structure is jointly composed of a support component 21 and a baffle component 22. The support component 21 serves as the outer layer structure of the upper cover 20, forming the outer inclined wall of the multi-faceted frustum, which is in direct contact with the external environment and can be adapted to the installation space of the UAV body. The baffle component 22 serves as the inner layer structure of the upper cover 20, forming the inner inclined wall of the multi-faceted frustum, with its inner wall surface directly facing the receiving cavity 50 formed by splicing with the equipment compartment 40.

[0038] Furthermore, the frustum-shaped multifaceted structure has inherent structural stability and high strength. Its sloping walls can effectively decompose the pressure and lateral impact force borne at the top into axial and radial components, and efficiently transmit them to the load-bearing structure 10 through the support component 21, greatly improving the overall mechanical robustness of the central control unit.

[0039] In one specific embodiment, the equipment compartment 40 further includes a wiring platform 60, which is arranged circumferentially along the equipment compartment 40; The cabling platform 60 includes: One end of the connecting rod 61 is located on the equipment compartment 40; The wiring ring plate 62 is spaced apart from the equipment compartment 40, and the other end of the connecting rod 61 is located on the wiring ring plate 62.

[0040] In one specific embodiment, through holes 621 are formed on the wiring ring plate 62 at intervals along the circumference for inserting antenna brackets.

[0041] Specifically, the equipment compartment 40 integrates a cabling platform 60 specifically for cable management and peripheral installation. This platform is arranged circumferentially around the equipment compartment 40, forming a ring structure surrounding it. The cabling platform 60 mainly consists of two core components: a connecting rod 61 and a cabling ring plate 62. One end of the connecting rod 61 can be fixed to the outer wall of the equipment compartment 40 by welding, bolting, or other methods, while the other end extends outward and connects to the cabling ring plate 62. This maintains a certain distance between the cabling ring plate 62 and the main body of the equipment compartment 40, thereby creating a three-dimensional and orderly cabling space around the equipment compartment 40.

[0042] Furthermore, various antenna feed lines and sensor cables can be led out from the side wall of the equipment compartment 40 and immediately guided into this dedicated annular space, where they are secured to the wiring ring plate 62 or connecting rod 61 using cable clamps or cable ties. This completely avoids cables hanging or piling up haphazardly around the equipment, greatly improving the professionalism and neatness of the equipment, and reducing the risk of failure caused by cable tangling and pulling.

[0043] In one specific embodiment, the equipment compartment 40 further includes a storage plate 70, which is detachably disposed in the receiving cavity 50 to divide the receiving cavity 50 into a first placement cavity 51 and a second placement cavity 52 along the vertical direction. The first placement cavity 51 is disposed on the side close to the upper cover 20.

[0044] Specifically, a detachable shelf 70 is added to the receiving cavity 50 inside the equipment compartment 40. The shelf 70 is arranged in a horizontal direction, and its edges can be detached from the inner wall of the receiving cavity 50 through detachable structures such as buckles, slots, and bolts, thereby achieving flexible assembly or separation from the receiving cavity 50.

[0045] Furthermore, the shelf 70 vertically divides the original monolithic receiving cavity 50 into two independent spaces: a first placement cavity 51 located at the top and a second placement cavity 52 located at the bottom. This division is not fixed; by disassembling the shelf 70, the overall space of the receiving cavity 50 can be restored to accommodate core boards or components of different heights and sizes.

[0046] Furthermore, the core board of the UAV central control unit often contains multiple functional modules, such as flight control board, image transmission board, power management board, etc. The first placement cavity 51 can be used to place boards that require frequent maintenance or have high heat dissipation requirements, such as the flight control core board. It is close to the upper cover 20 to facilitate heat dissipation through the ventilation structure of the upper cover 20. The second placement cavity 52 can be used to place relatively fixed or heavy modules, such as power modules. It is close to the load-bearing structure 10 to lower the overall center of gravity and avoid signal interference, poor heat dissipation, or disassembly interference caused by stacking different modules.

[0047] In one specific embodiment, the support component 21 has a plurality of first insertion holes 212, which are arranged horizontally around the support component 21 and penetrate through the support component 21 to connect with the first placement cavity 51; the equipment compartment 40 has a plurality of second insertion holes 41, which are arranged horizontally around the equipment compartment 40 and penetrate through the equipment compartment 40 to connect with the second placement cavity 52; the first insertion holes 212 and the second insertion holes 41 correspond one-to-one in the vertical direction.

[0048] Specifically, the horizontally distributed plug holes can match the peripherals arranged around the circumference of the UAV. Each plug hole corresponds to a specific peripheral, which facilitates quick location of the wiring source during later maintenance and solves the problem of troubleshooting difficulties caused by messy wiring in existing technologies. At the same time, the plug holes are located on the peripheral walls of the support component 21 and the equipment compartment 40, away from the disassembly and assembly paths of the connection part 23 of the upper cover 20 and the receiving cavity 50. When separating the upper cover 20 or removing the shelf 70 in the vertical direction, the wiring harness in the plug holes will not cause obstruction, ensuring smooth maintenance operations.

[0049] Furthermore, two clear and orderly rows of interfaces are formed on the side facade of the device. Users or maintenance personnel can clearly see that peripherals connected to the upper first connector 212 (such as the main antenna) serve the core board placed in the first placement cavity 51, while peripherals connected to the lower second connector 41 serve the modules in the second placement cavity 52. ​​This layout is intuitive and clear, greatly simplifying the installation and troubleshooting process.

[0050] Furthermore, all external wiring insertion and removal operations remain horizontal, conforming to ergonomics and conventional operating habits. However, when the upper cover 20 needs to be removed to replace the core board, the connection is operated vertically, and the two operating directions are orthogonal, completely avoiding interference between tools and operating space. Maintenance personnel can perform vertical disassembly directly without removing any circumferential cables.

[0051] In one specific embodiment, the load-bearing structure 10 includes a first support leg 11, a second support leg 12, a third support leg 13 and a fourth support leg 14. The first support leg 11 and the second support leg 12 are arranged opposite to each other, and the third support leg 13 and the fourth support leg 14 are arranged opposite to each other, with the four support legs forming a rectangular arrangement.

[0052] Specifically, the rectangular arrangement forms a stable support base. According to the principles of statics, four-point support defines a plane, making it a statically determinate structure. The arrangement of the support legs ensures that the equipment's center of gravity projection falls within the support polygon, guaranteeing stability. The extension of the legs increases the lever arm, improving anti-overturning capability. From a vibration isolation perspective, the support legs can act as vibration dampers, and their stiffness and damping parameters can be optimized for typical environmental frequencies. Material selection considers specific stiffness and specific strength, with aluminum alloys or composite materials being preferred.

[0053] Therefore, the aforementioned central control unit with replaceable core board is supported by a load-bearing structure 10. The upper cover 20 is vertically mounted on the load-bearing structure 10 and functionally divided into a support assembly 21 and a baffle assembly 22. A connecting portion 23 extending radially along the central axis of the upper cover 20 is provided between the two. A connector extends vertically from top to bottom into the connecting portion 23, detachably locking the support assembly 21 and the baffle assembly 22. An equipment compartment 40 is sandwiched between the load-bearing structure 10 and the upper cover 20. The upper cover 20 and the equipment compartment 40 are vertically aligned to form a receiving cavity 50 to house the core board. During maintenance, only the connector needs to be unlocked vertically to separate the two functional sections of the upper cover 20 and directly open the receiving cavity 50, avoiding tool interference with the circumferential antenna support and feeder clamps.

[0054] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
