Abstract
Description
Technical Field
[0001] This utility model belongs to the field of low-altitude aircraft technology, specifically a micro-fuel power module for low-altitude aircraft with a structure that is easy to assemble and disassemble. Background Technology
[0002] With the widespread application of short-endurance, low-altitude unmanned platforms in reconnaissance, mapping, logistics, and emergency response missions, there is a growing demand for power systems that are small in size, have high power-to-weight ratio, fast response, and are easy to maintain. Micro-fuel propulsion modules, with their compact structure and high energy density, have become one of the mainstream options. Meanwhile, diverse operational and civilian maintenance environments often require rapid replacement and repair in the field or under limited conditions, necessitating modularity, replaceability, and ease of rapid on-site assembly and disassembly of the power modules.
[0003] A hybrid electric vehicle module for unmanned aerial vehicles (UAVs) with application number CN201921431188.X includes an engine, a motor, and a mounting plate. The stator of the motor is fixed to the crankcase of the engine, and the rotor of the motor is driven to the crankshaft of the engine. The output end of the engine is driven to the power output shaft through a transmission system. The transmission system includes small multi-wedge pulleys, multi-wedge belts, and large multi-wedge pulleys. The output end of the engine is fixed with small multi-wedge pulleys, and the power output shaft is fixed with large multi-wedge pulleys. The small multi-wedge pulleys and the large multi-wedge pulleys are driven to each other through a multi-wedge belt.
[0004] However, the following problems were found in the implementation of the relevant technology: during installation, it requires multiple alignments and positioning and fixing with bolts or pins one by one. The disassembly and assembly process is cumbersome and highly dependent on professional tools and fixtures. On-site maintenance time is long, which affects the continuity of the task. At the same time, when parts need to be replaced, the whole thing needs to be replaced, and individual parts cannot be removed and replaced, resulting in high maintenance costs in the later stage.
[0005] To address this, we propose a micro-fuel propulsion module for low-altitude aircraft with a structure that is easy to assemble and disassemble quickly. Utility Model Content
[0006] To address the problems mentioned in the background art, this utility model provides a low-altitude aircraft micro-fuel power module with a structure that facilitates quick assembly and disassembly. It features a positioning structure that reduces the time spent on hole alignment, improving work efficiency and installation accuracy. Furthermore, it adopts a segmented installation method, which allows for maintenance by removing only the affected modules without requiring complete disassembly.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a low-altitude aircraft micro-fuel propulsion module with a structure that is easy to assemble and disassemble quickly, comprising a lower support shell, a positioning groove provided on the lower support shell, a positioning hole and a first threaded hole provided in the positioning groove, a power module body installed inside the lower support shell, a base fixedly connected to the outer surface of the power module body, a positioning plate fixedly connected to the outer surface of the power module body, a positioning block fixedly connected to the lower surface of the positioning plate, a first bolt provided on the positioning plate, an upper support shell installed on the lower support shell, second bolts installed on the lower and upper support shells, slots provided on both sides of the lower and upper support shells, clamp flanges installed on the slots, a second flange installed on the outer surface of the clamp flanges, and a connecting pipe fixedly connected to the other side of the second flange.
[0008] Preferably, the base is provided with a second threaded hole, and the lower support shell and the upper support shell are fixed to the base through the second threaded hole and the second bolt.
[0009] Preferably, the positioning plate, the lower support shell, and the upper support shell are provided with recessed holes, and the first bolt and the second bolt are located in the recessed holes.
[0010] Preferably, the positioning block is movably connected to the positioning hole, and the first bolt is threadedly connected to the first threaded hole.
[0011] Preferably, the positioning plate is movably connected to the positioning groove.
[0012] Preferably, the outer diameter of the base is equal to the inner diameter of the lower support shell, and the base is in contact with the lower support shell and the upper support shell.
[0013] Preferably, two mounting plates are fixedly connected to the outer surfaces of the lower support shell and the upper support shell, and a third bolt is provided on the mounting plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model, through the cooperation of positioning groove, positioning hole, first threaded hole, positioning block, first bolt, base and positioning plate, can reduce the time for hole alignment. During assembly, it is only necessary to align the positioning features to quickly put it in place, reducing the time for alignment or hole alignment one by one. Quick disassembly and assembly save downtime, improve work efficiency, and ensure consistent position during each assembly, reduce human error and improve installation accuracy.
[0016] 2. This utility model, through the cooperation of the lower support shell, the slot, the clamp flange, the second flange, the connecting pipe and the upper support shell, allows the power module installation section and the connecting pipe to be installed in sections. The power module section is installed separately in sections and modularly. Only the affected modules need to be removed, without the need for overall disassembly, which significantly shortens downtime and improves efficiency. Furthermore, consumable parts or small modules can be replaced individually, avoiding the need for expensive replacement of large assemblies. Attached Figure Description
