Description

Technical Field

[0001] This utility model belongs to the field of detection technology, and in particular to a shock-resistant high-speed railway hazard source detection board kit mounted on a drone. Background Technology

[0002] With the widespread application of drone technology in the detection of hazardous sources along high-speed railways, the high-performance computing boards mounted on drones need to process the collected data in real time, typically relying on multi-board collaborative computing to meet real-time requirements. However, the high-speed flight and strong vibration environment of drones pose a severe challenge to the reliability of the connection between the computing boards and the base plate. Currently, most computing boards are fixed to the base plate using traditional pluggable connectors, but under continuous vibration, problems such as poor contact and loose connector connections can easily occur, leading to system interruption or data loss, seriously affecting the safety of the detection mission. In addition, due to the limited internal space of drones, computing boards are usually densely packed in a compact cavity, resulting in insufficient operating space for replacing faulty boards or upgrading software, leading to low maintenance efficiency. Although some solutions attempt to add simple pluggable structures to the side of the boards, their shock resistance and ease of operation still cannot meet the special operating conditions of drones.

[0003] Insufficiency of existing technology: 1. Poor vibration resistance and reliability: Traditional pluggable connectors lack an adaptive locking mechanism for vibration environments, and are prone to loosening or poor connection under the high-frequency vibration of drones, resulting in insufficient system stability; 2. Difficult to maintain and operate: The circuit boards in the narrow space lack an effective auxiliary lifting and pulling structure. Manual operation is prone to damage to adjacent circuit boards or interfaces due to uneven force, and it is difficult to quickly align and plug them in. 3. Insufficient scalability: In multi-board collaboration scenarios, traditional connection methods make it difficult to achieve hot-swapping and rapid reconfiguration of boards, affecting the efficiency of system upgrades and fault recovery. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a shock-resistant high-speed railway hazard source detection board kit mounted on a drone. While ensuring a high-density layout, it improves connection reliability through a composite anti-vibration mechanism of mechanical locking and elastic deformation. Furthermore, the guide rail design of the puller can avoid interface damage caused by traditional blind operation.

[0005] The technical problem solved by this utility model is achieved through the following technical solution: A shock-resistant high-speed railway hazard source detection board kit for drones includes a high-density computing board and a sliding rail double-hook puller. The high-density computing board is installed in the drone chassis, and the sliding rail double-hook puller is used to pull out the high-density computing board installed in the drone chassis.

[0006] Furthermore, the high-density computing board includes a processor, a computing unit, a memory, a power supply, board recesses, locking strips, and connectors. The processor, computing unit, memory, and power supply are embedded on the surface of the high-density computing board. Board recesses are provided on the top of both sides of the high-density computing board, and locking strips are provided on both sides of the high-density computing board. The connectors are installed at the bottom of the high-density computing board and are used for electrical connection between the high-density computing board and external modules, responsible for transmitting signals and data.

[0007] Moreover, the locking strips are symmetrically embedded on both sides of the high-density computing board, and the hollow structure inside the locking strips integrates a spiral expansion mechanism.

[0008] Furthermore, the locking bar includes a knob and a screw rod, wherein the knob and the screw rod are connected by a thread.

[0009] Moreover, the slide rail type double hook puller includes a bidirectional synchronous slide rail, a rotating handwheel, a locking bolt, and an L-shaped hook claw. The end of the bidirectional synchronous slide rail is connected to the handwheel via a gear rack. The handwheel is used to drive the hook claw bases on both sides to move synchronously. The L-shaped hook claw is connected to the bottom of the bidirectional synchronous slide rail via a locking bolt.

[0010] Furthermore, the slide rail type double hook puller also includes a lifting handle, which is located above the bidirectional synchronous slide rail. The lifting handle is equipped with a pressure sensor to detect the pulling force and prevent mechanical damage to the board interface or chassis guide rail.

[0011] Furthermore, the bidirectional synchronous slide rail is symmetrically equipped with linear guide rails with scale markings on both sides of the slide rail for precise adjustment of the hook claw spacing. The slide rail surface is provided with a limit groove with locking bolts to ensure that there is no offset after the spacing is fixed, thus avoiding positioning deviation caused by loosening during operation.

[0012] Furthermore, the inner side of the L-shaped hook claw is covered with a high-friction coefficient silicone layer at the groove of the plate card, and the end is designed as an elastic pre-tightening barb structure.

[0013] The advantages and positive effects of this utility model are: 1. This utility model utilizes a spiral expansion design with retractable locking strips on both sides to create an interference fit between the circuit board and the chassis rails. Combined with a composite anti-vibration mechanism of elastic deformation and mechanical locking, it significantly improves connection stability under high-speed flight and strong vibration conditions of the UAV, avoiding the problems of loosening and poor connection common with traditional plug-in connectors. The retracted state of the locking strips defaults to standard plug-in procedures, supporting hot-swapping and rapid reconfiguration of circuit boards. This allows for flexible adjustment of computing power configuration when UAV mission requirements change. Furthermore, the sliding rail-type puller can accommodate various circuit board specifications, enhancing the overall scalability of the system.

[0014] 2. This utility model's sliding rail type double hook lifting device adopts bidirectional synchronous adjustable hook claws, achieving precise alignment and one-button operation for board replacement. No tools are required, reducing single-person operation time and significantly lowering maintenance time costs, making it particularly suitable for field or high-altitude operations. The lightweight crossbeam assembly and retractable sliding rail design ensure a high-density board layout while adjusting the hook claw spacing to adapt to the compact internal space and board installation tolerances of the drone, avoiding replacement difficulties caused by space constraints. The pressure sensor integrated into the lifting handle monitors the lifting force in real time and triggers an over-limit alarm, effectively preventing interface damage caused by forceful insertion and removal, and reducing the rate of human error.

Detailed Implementation

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] A shock-resistant high-speed railway hazard source detection board kit for drones includes a high-density computing board and a sliding rail double-hook puller. The high-density computing board is installed in the drone chassis, and the sliding rail double-hook puller is used to pull out the high-density computing board installed in the drone chassis.

[0019] like Figure 1As shown, the high-density computing board includes a processor 1-1, a computing unit 1-2, a memory 1-3, a power supply 1-4, a board groove 1-5, a locking strip 1-6, and a connector 1-7. The processor, computing unit, memory, and power supply are embedded on the surface of the high-density computing board. The top of both sides of the high-density computing board has a board groove with a depth of 3mm and an arc radius of 8mm. The surface is nickel-plated. The locking strips on both sides of the high-density computing board are made of phosphor bronze and have an internal hollow structure integrating a spiral expansion mechanism. The connector is installed at the bottom of the high-density computing board and is used for electrical connection between the high-density computing board and external modules, responsible for transmitting signals and data.

[0020] like Figure 2 As shown, the locking strips are symmetrically embedded on both sides of the high-density computing board. The hollow structure inside the locking strips integrates a spiral expansion mechanism. The locking strips include a knob 2-1 and a spiral rod 2-2, wherein the knob and the spiral rod are connected by threads. Every 90° rotation of the knob drives the locking strip to expand outward by 0.3mm, with a maximum expansion of 1.2mm.

[0021] The slide rail type double hook puller is a specialized operating device designed to meet the directional and standardized operation requirements within the confined space of an unmanned aerial vehicle (UAV) cabin. It is used only during board maintenance. Made of lightweight aluminum alloy, the slide rail type double hook puller includes a bidirectional synchronous slide rail 3-2, a rotating handwheel 3-2, a locking bolt 3-4, and an L-shaped hook 3-5. The end of the bidirectional synchronous slide rail is connected to the handwheel via a gear and rack. The handwheel drives the synchronous movement of the hook bases on both sides, with an adjustment range of 50-200mm. The L-shaped hook is connected to the bottom of the bidirectional synchronous slide rail via a locking bolt. After tightening the locking bolt, a torque of 6 N·m is applied to fix the hook position. The L-shaped hook is made of 304 stainless steel with an inner silicone layer (2mm thick, coefficient of friction μ≥0.8). It features an elastic barb at the end, with a spring steel sheet pre-compression design. After being embedded in the board groove, the barb rebounds at a 15° angle, and the locking force is ≥30N.

[0022] The slide rail type double hook puller also includes a lifting handle, which is located above the bidirectional synchronous slide rail. The lifting handle is equipped with a pressure sensor 3-1 to prevent mechanical damage to the board interface or chassis guide rail. The range is 0-100N. When the range exceeds 50N, a buzzer and LED red light alarm are triggered.

[0023] The bidirectional synchronous slide rail has symmetrical linear guide rails with scale markings on both sides for precise adjustment of the claw spacing. The slide rail surface has a limit groove with locking bolts to ensure that there is no offset after the spacing is fixed, avoiding positioning deviation caused by loosening during operation.

[0024] The inner side of the L-shaped claw is covered with a high-friction coefficient silicone layer where it fits into the groove of the card, and the end is designed with an elastic pre-tightening barb structure. When the claw is embedded in the groove at the top of the card, the barb is automatically rebounded by the pressure of the inner wall of the groove, forming a mechanical anti-disengagement lock, which effectively prevents the claw from accidentally coming off during the lifting process.

[0025] The slide rail is connected to an adaptive hook base. By rotating the handwheels at both ends of the crossbeam to drive the gear rack mechanism, the distance between the L-shaped hooks on both sides can be adjusted synchronously. The adjustment range is suitable for boards with a width of 50-200mm.

[0026] The construction principle of this utility model is as follows: after the board is inserted into the chassis guide rail, rotating the knob causes the spiral rod to push the wedge block to squeeze the inner wall of the locking strip, forcing the locking strip to expand radially and form an interference fit with the chassis guide rail, with a static friction force ≥200N.

[0027] This component achieves dynamic vibration resistance and safe insertion / removal through the coordinated action of retractable locking strips on both sides of the high-density computing board and a sliding rail-type pull-out device: When the board is inserted into the chassis, the locking strips are in a retracted state to reduce insertion resistance; after full insertion, the locking strips expand radially (0.5-1.2mm) via a tail knob driven by a spiral expansion mechanism, forming an interference fit with the chassis guide rail. It absorbs vibration energy through friction and elastic deformation, withstanding 15G acceleration impacts; the arc-shaped slot on the top of the board precisely aligns with the pull-out device's anti-disengagement hook, triggering the elastic hook lock through downward pressure via the sliding rail guide. During vertical lifting, the silicone friction layer is evenly stressed, and a pressure sensor monitors the lifting force in real time (an alarm sounds if the force exceeds 50N), ensuring safe removal from confined spaces without visual intervention. The system, through a composite mechanism of mechanical locking, elastic damping, and intelligent feedback, balances high-density layout, vibration resistance stability, and rapid maintenance requirements.

[0028] The usage process of this utility model is as follows: 1. Board insertion and locking process With the knob in its initial position, the locking bar retracts to its minimum outer diameter (25mm). Push the board into the chassis along the guide rail, with an insertion force ≤15N. After the board is fully inserted, rotate the knob 90° clockwise. The helical rod pushes the wedge block, causing the locking bar to expand to 26.2mm, forming an interference fit with the guide rail.

[0029] Technical benefits: The expansion locking mechanism improves the board's vibration resistance by 300% and increases the insertion and removal life to over 5000 cycles.

[0030] 2. Slide rail type double hook lifting operation procedure Rotate the handwheel to adjust the hook spacing to the card width (e.g., 150mm), and tighten bolt 3-2. Press down the handle to make the hooks engage with the card grooves, and the hooks will automatically lock. Pull the handle vertically; the sensor monitors the pulling force in real time, and an alarm will sound when the pulling force is greater than 50N to ensure safe removal.

[0031] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model includes, but is not limited to, the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
