Abstract
Description
Technical Field
[0001] This application relates to the field of power connection technology, and in particular to a power suspension device and an aircraft. Background Technology
[0002] In recent years, aircraft technology, represented by drones, has developed rapidly and has been widely used in fields such as aerial photography, surveying and mapping, logistics, and agricultural plant protection. These aircraft are usually powered by batteries, so the battery's endurance and replacement efficiency directly affect the aircraft's operational efficiency.
[0003] In existing technologies, there are two main methods for fixing batteries to the aircraft fuselage. The first method involves setting up a battery compartment inside the fuselage and placing the battery inside. While this method offers better overall integrity, it typically requires opening a hatch on the fuselage to install or remove the battery, making the operation cumbersome. Furthermore, the battery compartment's size is relatively fixed, limiting the types of batteries that can be used and resulting in poor versatility.
[0004] The second method involves securing the battery or battery box to the aircraft via an external mechanical structure, such as using straps, clips, or screws. While this external design improves the flexibility of battery replacement to some extent, it still has significant drawbacks. Using straps or screws for installation and removal is time-consuming and cumbersome, especially in situations requiring frequent battery changes, significantly reducing work efficiency. While using ordinary clips improves installation and removal speed, the stability and reliability of the connection cannot be fully guaranteed under the high-intensity vibration environment of the aircraft, posing a risk of accidental battery detachment. More importantly, after mechanically securing the battery, operators usually need to manually plug and unplug the battery's power connector from the aircraft's electrical connector. This not only adds an extra step and prolongs preparation time, but also, in confined spaces or poor lighting conditions, easily leads to missed connections or loose connections, directly affecting the normal operation of flight missions.
[0005] Therefore, designing a battery installation method that is simple in structure, easy to operate, reliable in connection, and can integrate mechanical fixation and power transmission is a technical problem that urgently needs to be solved in fields such as drones. Utility Model Content
[0006] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a power suspension device and an aircraft capable of simultaneously completing mechanical fixation and electrical connection.
[0007] In a first aspect, embodiments of this application provide a power supply suspension device.
[0008] The power suspension device of this application embodiment includes: a battery compartment, on which at least one first electrical connector is provided; a hook assembly, which is used to fix to an external electrical device, the hook assembly including at least one hanging post and at least one second electrical connector corresponding to the first electrical connector, the second electrical connector being pluggable to the first electrical connector; a groove assembly, which is fixed to the battery compartment, the groove assembly including a plurality of groove sleeves corresponding one-to-one with the hanging post, the battery compartment being nested in the hanging post through the groove sleeves to be hooked to the hook assembly, and the second electrical connector being pluggable to the first electrical connector; and at least one locking component, which is disposed on either the hook assembly or the groove assembly, for locking the relative position of the groove assembly and the hook assembly.
[0009] The power suspension device according to the embodiments of this application has at least the following beneficial effects: The power suspension device of this application, by setting mutually cooperating hanging posts and grooved sleeves, achieves vertical suspension installation of the battery compartment. The operator only needs to align the grooved sleeve of the battery compartment with the hanging post on the electrical equipment and slide it in along the direction of gravity to complete the mechanical installation. The entire process is simple and quick, greatly improving battery replacement efficiency. More ingeniously, this application sets the first electrical connector and the second electrical connector respectively on the battery compartment and the hook assembly, with their positions corresponding. Thus, during the vertical installation process of hanging the battery compartment onto the hook assembly, the two electrical connectors can automatically align and plug in, thereby combining the two steps of mechanical fixing and electrical connection into one. This not only completely eliminates the extra operation of manually plugging and unplugging the power connector, but also eliminates the risk of equipment power failure due to forgetting to plug in or improper connection, and significantly simplifies the overall operation process. In addition, the locking component can lock the relative position of the battery compartment and the hook component after the battery compartment is installed, ensuring the stability and reliability of the connection. This effectively prevents the battery from accidentally loosening or falling off due to vibration during operation (such as when an aircraft is in flight), thus ensuring the safe operation of the electrical equipment.
[0010] According to some embodiments of this application, the locking component is disposed on the hook component, the locking component includes a retractable locking pin, the groove component has a locking groove at the corresponding position of the locking pin, the locking groove is adapted to the locking pin, and when the groove is nested in the hook post, the locking pin is engaged in the locking groove.

[0014] A guide component, disposed within the receiving cavity, is used to limit the extension and retraction direction of the locking pin;
[0015] The unlocking lever is pivotally connected to the side wall of the receiving cavity. One end of the unlocking lever abuts against the locking pin, and the other end extends out of the receiving cavity. When the end of the unlocking lever extending out of the receiving cavity is operated, it drives the other end to overcome the elastic force of the locking element, causing the locking pin to retract into the receiving cavity.
[0016] According to some embodiments of this application, the guiding component includes a guide rod, one end of which is disposed on the inner sidewall of the receiving cavity, and the other end of which points to the locking groove, and the locking pin is movably inserted into the other end of the guide rod;
[0017] The locking elastic element includes a locking spring, which is sleeved on the outside of the guide rod, and its two ends abut against the surface of the locking pin and the inner wall of the receiving cavity, respectively.
[0018] The bottom of the locking pin is provided with a groove, and one end of the unlocking lever abuts against the inner wall of the groove.
[0019] According to some embodiments of this application, the unlocking lever is interference-fitted with the side wall of the accommodating cavity to achieve rotational positioning of the unlocking lever.
[0020] According to some embodiments of this application, the cross-sectional area of the mounting post increases sequentially from top to bottom.
[0021] According to some embodiments of this application, the mounting post is provided with a first guide angle on the side away from the battery compartment, and the other side opposite to this side is vertically arranged and provided with the locking pin.
[0022] According to some embodiments of this application, the battery compartment further includes a compartment body and a compartment cover. The groove assembly is fixedly connected to the compartment body. The top of the compartment body is provided with an opening. The edge of the compartment cover is provided with a flange. When the compartment cover is closed with the compartment body, the flange covers the top of the side wall of the compartment body.
[0023] Secondly, embodiments of this application also provide an aircraft.
[0024] The aircraft is provided with a power suspension device according to any embodiment of the first aspect.
[0025] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0041] In the existing technology, the mechanical connection process between the battery compartment and the electrical equipment is relatively cumbersome, and it also requires the plugging and unplugging of electrical connectors separately.
[0042] Therefore, this application provides an electrical connector and an aircraft that can solve the problems existing in the prior art. The technical solutions provided in this application will be described in detail below.
[0043] In a first aspect, embodiments of this application propose a power supply suspension device.
[0044] This application provides a power supply suspension device, which can be widely used in various electrical devices that require rapid power replacement, especially drones and robots. In subsequent embodiments, the application of this power supply suspension device to a drone will be used as an example for illustration.
[0045] like Figure 1 and Figure 2 As shown, the power suspension device in this embodiment mainly includes a hook assembly 200 fixed to the underside of the drone fuselage, and a battery compartment 100 for accommodating the battery and detachably connected to the hook assembly 200. Specifically, the battery compartment 100 is a box-shaped structure with internal space for accommodating and securing the battery (e.g., a lithium battery pack). The battery compartment 100 can be made of lightweight, high-strength engineering plastics or carbon fiber composite materials to reduce overall weight. One or more first electrical connectors 130 are provided on a specific mounting surface of the battery compartment 100. These first electrical connectors 130 are electrically connected to the positive and negative terminals of the battery inside the battery compartment 100, serving as an interface for power output. The first electrical connector 130 is preferably a plug-type structure and can be a high-current, high-reliability connector model.
[0046] The hook assembly 200 serves as a connection base, securely mounted to the fuselage (e.g., belly or arm) of the drone using screws or other methods. Figure 3 and Figure 4 As shown, the hook assembly 200 includes a base plate and at least one hook post 210 extending vertically from the base plate. In this embodiment, two hook posts 210 can be provided, symmetrically distributed, to increase the stability of the connection. The hook posts 210 are preferably made of a metal material (such as aluminum alloy) to ensure sufficient structural strength. On the base plate of the hook assembly 200, corresponding to the position of the first electrical connector 130 on the battery compartment 100, a corresponding second electrical connector 220 is provided. This second electrical connector 220 is electrically connected to the flight control system or power system inside the UAV. Figure 2 and Figure 3 As shown, when the battery compartment 100 is installed in place, the first electrical connector 130 can be inserted into the second electrical connector 220 to form a complete power supply circuit.
[0047] like Figures 1 to 3 As shown, to enable quick assembly and disassembly of the battery compartment 100 and the hook assembly 200, a groove assembly 300 is also fixedly connected to the battery compartment 100. The groove assembly 300 includes several groove sleeves 310, the number, position, and shape of which correspond one-to-one with and match the hook posts 210 on the hook assembly 200. Each groove sleeve 310 is a hollow structure, and its inner wall contour matches the outer contour of the hook post 210.
[0048] During installation, the operator holds the battery compartment 100 and aligns the openings of the groove sleeves 310 of the groove assembly 300 with the corresponding hook posts 210 on the hook assembly 200, then slides it downwards in the vertical direction (i.e., the direction of gravity). Under its own weight, the groove sleeves 310 of the battery compartment 100 smoothly fit into the hook posts 210, thus securely "hanging" the battery compartment 100 onto the drone body, completing the mechanical connection. During this sliding installation process, the first electrical connector 130 on the battery compartment 100 and the second electrical connector 220 on the hook assembly 200 also synchronously and automatically complete the alignment and insertion, achieving electrical connection. The entire process requires no visual alignment of the tiny plugs and no extra force, making the operation intuitive and extremely fast.
[0049] To prevent the battery compartment 100 from accidentally loosening or detaching due to severe vibrations during flight, the power suspension device in this embodiment is also equipped with at least one locking component 400. For example, this locking component 400 can be located on the hook component 200 or the groove component 300. Its function is to automatically or manually lock the two components after the battery compartment 100 is fully engaged, preventing accidental relative displacement. For instance, the locking component 400 can be a simple elastic buckle that automatically springs into a preset slot when the battery compartment 100 is fully installed; unlocking is achieved simply by pressing or flicking the buckle. This design ensures that the connection between the battery compartment 100 and the fuselage remains secure and reliable even under complex flight attitudes and high-intensity maneuvers.
[0050] In summary, the power supply suspension device of this embodiment cleverly integrates the mechanical suspension structure with the electrical connector. A simple vertical mounting action simultaneously completes the mechanical fixation and electrical connection of the battery, and the same applies to disassembly. This not only greatly simplifies the operation steps and shortens the battery replacement time, but also fundamentally avoids human error such as missing or loose electrical connectors, significantly improving the convenience and safety of the equipment.
[0051] In some embodiments, to achieve a secure and convenient locking mechanism, such as... Figure 5 As shown, the locking component 400 is preferably integrated inside the hook post 210 of the hook assembly 200. Typically, the number of locking components 400 corresponds to the number of hook posts 210 on the hook assembly 200, forming a multi-point locking system to ensure absolute reliability of the connection. For example, as... Figure 7 As shown, the interior of each mounting post 210 is designed as a hollow structure, forming a receiving cavity. The core component of the locking assembly 400 is installed within this receiving cavity. A retractable locking pin 410 is provided here, which can extend out of the side wall of the mounting post 210 or retract into the receiving cavity within a preset travel range. Correspondingly, as... Figure 6 As shown, a locking groove 311 is precisely formed on the inner side wall of the groove sleeve 310 of the battery compartment 100, which is adapted to the shape, size and final position of the locking pin 410. When the groove sleeve 310 of the battery compartment 100 is fully inserted into the hook post 210, the locking pin 410 can be aligned with the locking groove 311.
[0052] Understandably, in order to achieve the automatic locking and manual unlocking functions of the lock pin 410, such as Figure 7As shown, the receiving cavity also cleverly incorporates the following components: First, to limit the locking pin 410 to linear movement only in a specific direction (i.e., the direction of extension or retraction) and prevent it from wobbling or rotating within the cavity, a guide component is provided within the receiving cavity. For example, this guide component is one or more guide rods 420. One end of the guide rod 420 is firmly fixed to the inner wall of the receiving cavity, and its shaft points towards the locking groove 311 on the groove sleeve 310. The locking pin 410 has a through hole, allowing it to be movably inserted (sleeved) onto the guide rod 420 and slide along its axis. Second, to give the locking pin 410 the ability to automatically lock, a locking elastic element, such as a locking spring 430, is provided within the receiving cavity. This spring is preferably a helical compression spring, which is also sleeved on the outside of the guide rod 420, with its two ends abutting against the inner surface of the locking pin 410 and the inner wall of the receiving cavity, respectively. In its natural state, the spring is in an extended position, and its elastic force continuously pushes the locking pin 410 toward the extended position. Therefore, when the grooved sleeve 310 slides into place and the locking groove 311 aligns with the locking pin 410, the locking pin 410 will automatically and quickly "spring" into the locking groove 311 under the action of the spring force, accompanied by a clear "click" sound, providing the operator with clear locking feedback. Finally, to achieve unlocking, an unlocking lever 440 is pivotally connected to the side wall of the receiving cavity. This lever acts like a lever, with one end extending into the receiving cavity and abutting against the locking pin 410; the other end passes through the wall of the hanging post 210 and is exposed to the outside for easy access by the operator. To achieve efficient force transmission, a groove 411 can be provided on the bottom (or side) of the locking pin 410, and the inner end of the unlocking lever 440 is in contact with the inner wall of the groove 411. When the battery compartment 100 needs to be removed, the operator simply needs to flick or press the outer end of the unlocking lever 440 with their finger. The lever will then rotate around its pivot, and its inner end will push the groove 411 of the locking pin 410, overcoming the elastic force of the locking spring 430, causing the locking pin 410 to retract into the receiving cavity along the guide rod 420. Once the locking pin 410 is completely disengaged from the locking groove 311, the battery compartment 100 can be smoothly lifted vertically upwards and removed. Furthermore, to improve the user experience, the unlocking lever 440 and its pivot connection point on the side wall of the receiving cavity can be interference-fitted. This fit utilizes the elastic deformation of the material to generate a preload, giving the lever a certain damping feel during rotation and allowing it to stably remain at any rotational position. For example, when the operator moves the lever to the "unlock" position, even if the finger is released, the lever can remain in that position due to friction, instead of immediately springing back under the indirect action of the spring force. This allows the operator to easily remove the battery compartment 100 with both hands without having to keep pressing the unlocking mechanism.
[0053] Through the above combination design, the locking component 400 of this application forms a highly integrated and reliable locking / unlocking system, which perfectly matches the design intention of quick assembly and disassembly.
[0054] In some embodiments, the geometry of the mounting post 210 is optimized to further improve the ease of installation and fault tolerance. For example, the mounting post 210 is designed with its cross-sectional length increasing sequentially from top to bottom. For instance, one or more of its sides can be designed as inclined surfaces with a certain angle, making the entire mounting post 210 a wedge-shaped or trapezoidal post that is narrower at the top and wider at the bottom. The ingenuity of this design lies in its inherent guiding and securing functions. Correspondingly, the shape inside the groove sleeve 310 matches the shape of the mounting post 210. In the initial installation stage, the operator only needs to align the relatively wide opening of the groove sleeve 310 on the battery compartment 100 with the relatively narrow top of the mounting post 210 to easily begin the nesting process. This design provides a large alignment tolerance, eliminating the need for highly precise visual alignment by the operator, greatly reducing the difficulty of operation, especially in low light conditions or emergency situations requiring rapid operation. As the battery compartment 100 slides downwards under gravity or external force, the inner wall of the grooved sleeve 310 gradually contacts and fits against the inclined side of the mounting post 210. This process not only automatically corrects the initial positional deviation and guides the installation, but more importantly, when the grooved sleeve 310 is fully nested in place, its inner wall forms a very tight fit with the widened base of the mounting post 210. This wedge-shaped fastening effect effectively eliminates potential gaps between the two, preventing the battery compartment 100 from shaking after installation, and significantly enhancing the stability of the mechanical connection. Therefore, this tapered design, narrower at the top and wider at the bottom, not only makes the installation smoother and more forgiving, but also achieves a pre-tightening effect through the structure itself. Together with the aforementioned locking component 400, it ensures that the power suspension device achieves extremely high structural rigidity and vibration resistance after connection, which is particularly important for equipment such as aircraft that operate in high-vibration environments.
[0055] In a preferred embodiment, the geometry of the hook post 210 is asymmetrically optimized to achieve better synergy with the function of the locking assembly 400. For example, such as... Figure 5As shown, the mounting post 210 has a first guide angle 211 on the side away from the battery compartment 100 (i.e., the side closer to the body), causing this side to tilt outward from top to bottom. Meanwhile, the other side opposite this guide angle (i.e., the side closer to the main body of the battery compartment 100) remains vertical, and the aforementioned locking pin 410 for locking extends from this vertical sidewall. The core value of this asymmetrical design lies in its guiding and pre-tightening effect during installation. When the grooved sleeve 310 of the battery compartment 100 is nested into the mounting post 210 from top to bottom, its inner wall first contacts the first guide angle 211 of the mounting post 210. As the battery compartment 100 continues to slide downward, this tilted guide surface generates a lateral force that continuously and gently pushes the entire grooved sleeve 310 towards the side opposite the guide angle. This ingenious design ensures that the inner wall of the grooved sleeve 310, with its locking groove 311, fits tightly and without gaps against the vertical side wall of the hook post 210, which has the locking pin 410. This provides at least two significant benefits: First, it makes the locking feedback signal clearer. Because the grooved sleeve 310 is guided at an angle towards the locking side, once it slides into place, the locking pin 410 immediately and crisply snaps into the locking groove 311, with almost no delay or uncertainty. The operator can perceive a clearer and more distinct "click" sound and tactile feedback, thus confirming that the locking has been successful. Second, it makes the locking state more stable. By eliminating any potential play (gap) between the locking pin 410 and the locking groove 311, a tight surface-to-surface fit is achieved. This greatly enhances the vibration resistance and shock resistance of the connection, effectively preventing wear or abnormal noise caused by minor shaking during vigorous operation, and ensuring the long-term reliability of the connection.
[0056] In some embodiments, to further enhance the device's adaptability to complex environments such as outdoors, the battery compartment 100 has been optimized with waterproof and dustproof features. For example, the battery compartment 100 consists of a compartment body 110 and an openable cover 120. The compartment body 110 is used to accommodate battery cells or battery packs, and its top has an opening for inserting or removing batteries. A grooved assembly 300 for suspension is securely connected to the compartment body 110. Figure 8As shown, the key to its waterproof design lies in the integrally formed downward-extending flange 121 along the edge of the cover 120. When the cover 120 is closed with the body 110, this flange 121 naturally covers and encloses the top outer side of the side wall of the body 110, forming an overlapping, eaves-like protective structure. This structure effectively blocks rainwater, liquids, or dust splashed from above or the side. Even if liquid flows onto the surface of the cover 120, it will be guided by the flange 121 to the outer wall of the body 110 and flow down, preventing it from directly penetrating the joint between the cover 120 and the body 110, thus preventing it from entering the battery compartment 100 and damaging the battery itself or its internal circuitry. This design enhances the protection level of the battery compartment 100. As a further optimization, an elastic sealing ring (such as one made of rubber or silicone) can be added at the junction of the cover 120 and the body 110, for example, on the top outer edge of the body 100 or in the sealing groove formed inside the flange 121. When the cover 120 is closed, the flange 121 will compress the sealing ring, forming a more reliable airtight and watertight seal, thus enabling it to withstand more severe operating environments. In summary, this design, through simple structural improvements, provides reliable environmental protection for the internal battery and circuitry, ensuring the stable operation of the entire power system under harsh weather conditions such as rain, snow, humidity, or dust, significantly expanding the application scenarios of this power supply suspension device.
[0057] Secondly, embodiments of this application provide an aircraft.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
