Description

Technical Field

[0001] This utility model provides a drone battery structure, and particularly relates to a drone battery compartment structure with guide rail positioning. Background Technology

[0002] The drone battery compartment is the core structure of the drone's energy system. Its primary function is to provide a stable and reliable power supply to the aircraft and ensure the batteries are securely fixed during flight. Traditional battery compartments typically employ a fixed design, embedding one or a small number of battery modules into the fuselage and achieving electrical connections through rigid interfaces. This type of structure needs to balance lightweight, structural strength, and electrical stability, but due to its fixed installation mode, the type, quantity, and layout of batteries are difficult to dynamically adjust, making it difficult for drones to adapt to diverse mission requirements.

[0003] Existing drone battery compartments mostly employ separate plug-in interfaces or fixed mounting slot structures, requiring battery modules to connect to the drone's circuitry via independent interfaces. For example, some modular solutions use multiple independent battery compartments connected in parallel, but each battery requires separate wiring, leading to wiring redundancy, increased weight, and the plug-in interfaces are prone to poor contact during flight vibrations. Furthermore, the fixed battery types and capacities prevent flexible mixing and matching based on mission requirements, resulting in wasted range and payload capacity. Its core drawback lies in:

[0004] 1. Poor expandability and compatibility: Battery configuration is limited by fixed slots, making it impossible to add, remove, or replace different types of batteries as needed;

[0005] 2. Low electrical connection reliability: The plug-in interface relies on spring contacts, which are prone to wear after long-term use and are prone to power failure under vibration.

[0006] 3. Increased circuit complexity: Independent wiring for multiple batteries increases system complexity and the risk of failure. Utility Model Content

[0007] To address the aforementioned issues, this application provides a drone battery compartment structure with guide rail positioning, which solves the problems of low flexibility, poor positioning effect, and inconvenience in the use of existing drone battery compartments.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a UAV battery compartment structure with guide rail positioning, including at least one electrical guide rail, with guide rail positioning grooves extending along the length direction on both sides of the electrical guide rail, forming a connecting and receiving section between the guide rail positioning grooves; a battery assembly is slidably connected to the electrical guide rail; the battery assembly includes a battery body and sliding connection terminals at both ends thereon; the sliding connection terminals can slide into the guide rail positioning grooves and are electrically connected to the inner conductive layer of the electrical guide rail. Preferably, an elastic abutment component is provided between the sliding connection terminal and the guide rail positioning groove, including an elastic abutment piece on the sliding connection terminal and an abutment slope in the guide rail positioning groove. Preferably, the electrical guide rail is provided with a plurality of evenly distributed and penetrating slots, and a transmission line penetrating through itself and electrically connected to the sliding connection terminal is provided inside the slot.

[0009] Preferably, the sliding connection terminal includes a plurality of conductive plates that are compactly and slidably connected to the electrical guide rail, and an insulating rubber sleeve is provided between the plurality of conductive plates.

[0010] Preferably, the insulating rubber sleeve is slidably connected to the electrical guide rail.

[0011] Preferably, the battery body is provided with a power storage center that is electrically connected to the electrical guide rail, and the power storage center controls the power distribution; the end of the battery body near the electrical guide rail is provided with a sliding groove that corresponds to and engages with the electrical guide rail, and the two sides of the sliding groove are provided with fixing lugs that are fixedly connected to the outer shell of the battery plate.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] 1. With the help of electrical rails and sliding battery components, users can freely increase or decrease the number of different types of batteries according to flight needs, optimizing the balance between weight and performance.

[0014] The sliding connection terminals of the battery pack cooperate with the guide rail positioning groove to achieve plug-and-play functionality, eliminating the need to stop the machine to replace the entire battery pack.

[0015] 2. The elastic clamping assembly ensures that the battery remains in close contact with the guide rail even under vibration conditions by cooperating with the elastic clamping plate and the clamping slope, thus avoiding the risk of power failure.

[0016] An insulating rubber sleeve isolates the conductive plate, preventing short circuits during sliding and enhancing structural stability.

[0017] 3. The built-in transmission line on the guide rail centrally transmits power from each battery to the drone system, simplifying traditional complex wiring and improving maintenance efficiency.

[0018] The power storage center intelligently allocates power, optimizes battery usage sequence or parallel connection strategy, and extends overall range.

[0019] 4. The sliding groove and fixing ear ensure that the battery is firmly locked after installation to prevent displacement during flight.

[0020] The evenly distributed card slots allow batteries to be inserted at any position, supporting rapid reconfiguration.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] like Figure 1 and Figure 2 As shown, a drone battery compartment structure with guide rail positioning mainly includes at least one electrical guide rail 1, with guide rail positioning grooves 3 extending along its length on both sides. A connecting and receiving section 4 is formed between the two guide rail positioning grooves, and the battery assembly 2 is slidably connected to the electrical guide rail 1. The battery assembly 2 consists of a battery body 21 and sliding connection terminals 22 located at both ends of it. The sliding connection terminals 22 can slide into the guide rail positioning grooves 3 and achieve electrical connection with the inner conductive layer of the electrical guide rail 1. In addition, a number of through slots 11 are evenly distributed on the electrical guide rail 1. The slots 11 have transmission lines 5 that pass through them and are electrically connected to the sliding connection terminals 22. This constitutes the key main structure and basic connection method of the entire drone battery compartment.

[0033] In this implementation scheme, each component works closely together, playing a unique role and achieving numerous beneficial effects. Firstly, the electrical guide rail 1 serves as a fundamental component, with its two side guide rail positioning grooves 3 precisely engaging with the sliding connection terminals 22 of the battery assembly 2. This allows the battery assembly to slide smoothly along the guide rail, enabling plug-and-play functionality and providing a hardware foundation for flexible battery configuration to meet the needs of different flight missions, thus optimizing the balance between the drone's weight and performance. The elastic clamping component between the sliding connection terminal 22 and the guide rail positioning grooves 3 includes an elastic clamping plate and a clamping ramp. These two components work together to continuously apply elastic force during drone flight vibrations, ensuring tight contact between the battery and the guide rail, preventing electrical connections from loosening due to vibration, effectively mitigating the risk of power outages, and improving connection reliability.

[0034] The slots 11 on the electrical guide rail 1 are evenly distributed, with the built-in transmission line 5 running through and electrically connected to the sliding connection terminal 22. This design simplifies circuit wiring, reduces traditional complex wiring, lowers the failure rate, and improves maintenance convenience. Meanwhile, the sliding connection terminal 22 includes compactly arranged conductive plates 23 with insulating rubber sleeves 24 interspersed among them. This ensures electrical conduction and prevents short circuits during sliding, enhancing structural stability and safety. The insulating rubber sleeves are slidably connected to the electrical guide rail, further optimizing dynamic performance.

[0035] The battery compartment 21 houses a power storage center 6, electrically connected to the electrical rail 1. This allows for intelligent control of power distribution, flexibly adjusting the usage sequence or parallel operation strategy based on battery status and flight requirements to extend the drone's endurance. The sliding groove 25 and fixing lug 26 near the electrical rail on the battery compartment ensure a secure lock after installation, preventing displacement during flight and guaranteeing flight safety. Overall, this drone battery compartment structure integrates mechanical and electrical design, innovatively introducing a modular concept into battery configuration. Its ingenious structure addresses the pain points of traditional battery compartments, providing the drone industry with a more efficient, flexible, and reliable energy solution, enhancing the drone's mission adaptability and economy, and driving industry progress.

[0036] like Figure 2 and Figure 3 As shown, in this UAV battery compartment structure with guide rail positioning, an elastic clamping component is provided between the sliding connection terminal 22 and the guide rail positioning groove 3. This component includes an elastic clamping piece on the sliding connection terminal 22 and a clamping inclined surface in the guide rail positioning groove 3, effectively enhancing connection stability. The sliding connection terminal 22 includes several compact conductive plates 23 that are slidably connected to the electrical guide rail 1. An insulating rubber sleeve 24 is provided between each conductive plate 23, and the insulating rubber sleeve 24 is also slidably connected to the electrical guide rail 1, ensuring electrical connection while avoiding short circuit risk. A power storage center 6 electrically connected to the electrical guide rail 1 is provided between the battery bodies 21 for controlling power distribution. Fixing lugs 26 are fixedly connected to the outer shell of the battery body 21 on both sides of the sliding groove 25 near the electrical guide rail 1. These design details further optimize the performance and function of the battery compartment structure.

[0037] In this implementation plan, existing UAV battery compartment technologies typically employ fixed installation or limited modular designs for battery modules. For example, they connect to the UAV power system via standardized plug-in ports, requiring manual insertion of the battery pack into pre-set battery compartment slots and securing them with mechanical clips or straps to prevent loosening during flight. Some high-end solutions utilize a replaceable battery drawer-type structure, but battery replacement still requires manual removal of screws or levering of latches after the aircraft is stopped. Furthermore, different battery types cannot be mixed due to inconsistent interface specifications. Regarding electrical connections, existing technologies rely on metal springs or PogoPin contact conduction. After battery insertion, contact is maintained by spring pressure, which can lead to increased impedance or even power failure due to oxidation or vibration over long-term use. When multiple batteries are connected in parallel, additional wiring boards or independent cabling to the flight control system are required, increasing wiring complexity and weight. During operation, users must pre-select and fix a single battery type according to mission requirements, and the battery configuration cannot be dynamically adjusted during flight. Moreover, the battery management unit is typically designed for a single battery pack and cannot coordinate the charging and discharging priorities of multiple battery types. Furthermore, existing battery compartments lack a rapid positioning mechanism, requiring alignment with the slot and significant pushing force during installation to ensure electrical connection, which can easily cause interface wear. This device integrates the aforementioned dispersed mechanical fixing, electrical contact, and power distribution functions into one unit through a guide rail sliding connection and elastic clamping components. Users only need to push the battery assembly along the guide rail into the slot 11 position, and the conductive plate 23 of the sliding connection terminal 22 will automatically press against the conductive layer inside the guide rail. The insulating rubber sleeve 24 simultaneously completes physical limiting and insulation protection. The energy storage center 6 identifies the type and capacity of the connected battery in real time through the transmission line 5 and dynamically optimizes the output strategy. No tools or manual wiring are required throughout the process, significantly improving deployment efficiency and system reliability.

[0038] In the above implementation scheme, the circuit route of this device is as follows: the current starts from the battery body 21 of the battery assembly 2, and is connected to the inner conductive layer in the guide rail positioning groove 3 on both sides of the electrical guide rail 1 through the sliding connection terminals 22 at both ends. Then, through the transmission line 5 inside the electrical guide rail 1, it passes through the guide rail from the slot 11 and finally transmits the power to the power system of the UAV to achieve a stable power supply. At the same time, the power storage center 6 is electrically connected to the electrical guide rail 1, which can intelligently regulate the power distribution of each battery body 21 and optimize the power transmission and usage efficiency.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
