Description

Technical Field

[0001] This invention relates to the field of luggage equipment technology, specifically a military luggage case. Background Technology

[0002] Traditional military luggage boxes mostly adopt a fixed structure and have a single function, only used for carrying items, which is difficult to meet the needs of rapid mobility, covert transportation and personnel assisted movement in modern military operations.

[0003] Most existing suitcases rely on manual dragging or carrying, which can easily lead to personnel fatigue and affect combat effectiveness during long marches or in complex terrain. Although some products have added wheels, they cannot be ridden, making it difficult to meet the needs of rapid maneuverability and lacking autonomous movement capabilities. They require full human control, which can distract soldiers in a battlefield environment. The few existing smart suitcases mostly use Bluetooth or RFID technology for tracking, but their effective range is short, their anti-interference ability is poor, and they cannot work stably in environments with obstructed vision. Ordinary suitcases are made of ABS or polycarbonate materials, which are lightweight but lack sufficient protection and cannot withstand bullet or shrapnel attacks. Existing bulletproof cases are often too heavy, making them inconvenient for individual soldiers to carry. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a military luggage case.

[0005] To solve the above problems, the technical solution of the present invention is: a military luggage case, comprising: Half-box one, which is made of high-strength bulletproof composite material, is rotatably connected to half-box two via a hinge at the rear, so that the box can be folded or unfolded. A riding assembly, which is installed on the front side of the half-box, includes retractable plates and rods for forming a riding structure when the box is unfolded; The protective box is fixedly installed inside the lower part of the half-box. It integrates control circuits, sensors and power components to achieve autonomous following and electric drive. The base plate, located below half-box one and half-box two, is connected to the box body by bolts and serves as a support and driving foundation; The drive assembly, symmetrically positioned below the base plate, provides power for riding and movement.

[0006] Furthermore, the riding component includes: The telescopic board is telescopically connected to the front side of the half box via a sliding rail structure. A baffle is fixedly connected to the front side of its upper end for foot protection during riding. A through groove is opened in the middle of the telescopic board to reduce weight. The telescopic rod has its lower end connected to the inside of the baffle via a bearing, allowing it to be extended and retracted vertically for height adjustment. The handle is fixedly attached to the top of the telescopic rod and is covered with anti-slip material for easy operation; A miniature camera is embedded and fixed in the middle of the front end of the grip, and wirelessly connected to the controller inside the protective box. It is used to capture images in front and achieve autonomous following through algorithms. The steering wheel is connected to the lower end of the telescopic rod and works with the drive assembly to achieve steering control.

[0007] Furthermore, the telescopic rod includes: The outer tube is a metal cylindrical tube structure with an annular block on its outer side and an axial groove inside. A partition, which is welded and fixed inside the outer tube, is used for separation and support; A small servo motor is fixedly connected to a ring block by bolts, with its drive end pointing downwards. A rotating shaft is fixedly connected to the drive end of a small servo motor, and its lower end is connected to a steering wheel via a coupling to transmit steering torque. The inner tube is fitted inside the outer tube, and a convex strip is provided on its outer side. The convex strip cooperates with the groove inside the outer tube to achieve sliding connection and anti-rotation, so that the length of the telescopic rod can be adjusted electrically or manually.

[0008] Furthermore, the driving component includes: A servo motor is embedded and fixedly connected to a mounting slot in the middle of the base plate. A transmission wheel, which is fixedly connected to the drive end of the servo motor; A rotating rod, which is rotatably connected to the bottom plate via a bearing seat; The sleeve is interference-fitted and fixed to the rotating rod to reinforce the structure; Driven wheel, which is fixedly connected to the middle position of the rotating rod; The drive wheels are fixedly connected to both ends of the swivel and are made of rubber to enhance grip. The transmission belt is a synchronous belt, with its two ends respectively fitted onto the drive pulley and the driven pulley to form a closed-loop transmission.

[0009] Furthermore, several latches are fixedly connected to one side of the second half of the box. These latches are high-strength metal latches that correspond to the slots on the first half of the box, enabling the box to be quickly locked or released, ensuring stability in the folded state.

[0010] Furthermore, omnidirectional auxiliary wheels are fixedly connected to both sides of the lower end face of the base plate. These auxiliary wheels are made of wear-resistant and quiet materials and are used to assist movement in non-riding mode, thereby improving portability.

[0011] The advantages of this invention compared to existing technologies are: This invention utilizes the telescopic design of the riding component and the power output of the drive component to allow the suitcase to be quickly unfolded into a rideable structure, reducing the burden on passengers and improving mobility. By employing a miniature camera and an intelligent control system within the protective box, it achieves autonomous movement and following functions, reducing manual operation and adapting to complex environments. Half-box one and half-box two are made of bulletproof composite materials, effectively resisting bullet and fragment attacks and enhancing safety. The overall structure is compact, and when folded, it is similar in size to a regular suitcase, facilitating storage and transportation. Attached Figure Description

[0017] like Figures 1 to 7 As shown, the technical solution of the present invention is as follows: a military luggage case, wherein half-case 1 and half-case 2 are first connected by a rear hinge, allowing the case body to rotate around the hinge axis. Half-case 1 and half-case 2 are made of laminated bulletproof composite material polyethylene fiber and metal composite plate, and are filled with a buffer layer to ensure bulletproof performance.

[0018] like Figures 1 to 7 As shown, the riding component 3 is installed as follows: The telescopic plate 301 is inserted into the guide groove on the front side of the half-box 1 via its bottom slide rail, allowing the telescopic plate 301 to extend and retract horizontally. A baffle 302 is welded to the front side of the telescopic plate 301, and the lower end of the telescopic rod 303 is mounted inside the baffle 302 via a bearing. The outer tube 3031 of the telescopic rod 303 is fixed to the baffle 302, and the inner tube 3036 engages with the groove of the outer tube 3031 via a convex strip 3037, allowing for manual or electric height adjustment. A small servo motor 3034 is fixed in the annular block 3033, and its drive end shaft 3035 is connected to the steering wheel 306. A grip 304 is mounted on the top of the telescopic rod 303, and a miniature camera 305 is embedded and fixed to the front end of the grip 304, and connected to the controller inside the protective box 5 via a wire.

[0019] like Figures 1 to 7 As shown, the protective box 5 is fixed to the lower part of the half-box 1 with bolts. The box integrates a microcontroller, GPS module, wireless communication module and battery pack. The image data of the miniature camera 305 is processed by the processor to realize target recognition and autonomous following algorithm.

[0020] like Figures 1 to 7 As shown, the mounting base plate 6 and drive assembly 8 are installed: the base plate 6 is connected to the bottom of half-box 1 and half-box 2 via angle brackets. A servo motor 801 is fixed in the mounting groove in the middle of the base plate 6, and a transmission wheel 802 is mounted on its drive end. A rotating rod 805 is mounted below the base plate 6 via a bearing seat, a sleeve 803 and a driven wheel 804 are fixed to the rotating rod 805, and drive wheels 806 are mounted at both ends of the rotating rod 805. A transmission belt 807 is fitted onto the transmission wheel 802 and the driven wheel 804, and its tension is adjusted. Universal auxiliary wheels 7 are installed on both sides of the base plate 6 for balanced support. Several locking buckles 4 are welded to one side of half-box 2, corresponding to the slots on the side of half-box 1, for locking the box after folding.

[0021] like Figures 1 to 7 As shown, autonomous following control includes the following steps: Importing the route: The operator imports the route map into the equipment controller: Route Analysis: The controller performs route analysis, and the user controls the autonomous movement to start and stop. Image acquisition: The miniature camera 305 acquires images of the surrounding environment in real time at a frame rate of 30fps, automatically adjusts exposure parameters to adapt to different lighting conditions, and performs image preprocessing including Gaussian denoising and histogram equalization. Target recognition: The image processing module analyzes the image, identifies preset targets, and uses an improved YOLOv5 algorithm to identify operator features. Based on a deep learning-based target detection model, the recognition accuracy is >95%, and it supports multi-target tracking and re-recognition after occlusion. Deviation calculation: The controller calculates the distance and directional deviation between the suitcase and the target. The controller calculates the relative position with the target in real time and uses an adaptive PID control algorithm to generate control commands. The deviation judgment threshold can be dynamically adjusted according to actual needs. Command generation: Control commands are generated based on the deviation. The angle of the steering wheel 306 is changed by adjusting the speed of the servo motor 801 and the micro servo motor 3034. When the deviation exceeds the threshold, the speed of the drive wheel and the angle of the steering wheel are adjusted respectively. The drive wheel uses differential control to achieve precise steering, and the steering wheel controls the deflection angle through the servo motor. Execute movement: Drive component 8 drives the suitcase to move according to instructions to maintain its relative position with the target.

[0022] Feedback loop: Real-time updates of position and status information, continuous monitoring to ensure tracking stability, forming a complete closed-loop control system. In practical use, when riding mode is needed, unlock 4 to unfold half-box 1 and half-box 2 to a horizontal position. Pull the telescopic plate 301 to extend it, adjust the telescopic rod 303 to a suitable height, and position the handle 304 for easy operation. Start the servo motor 801, which drives the rotating rod 805 and drive wheel 806 to rotate via the transmission belt 807, achieving forward or backward movement. The miniature camera 305 captures images from the front, which are processed by the controller inside the protective box 5 to identify the operator and automatically adjust the direction for autonomous following. When folding is needed, retract the riding component 3, fold the box body, and lock it with the lock 4, allowing it to be towed as a regular suitcase.

[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto.
