AI Technical Summary
Technical Problem
The output energy of the existing drone engine ignition coil is insufficient and cannot meet the safe flight requirements of drones.
Method used
Design a single-coil dual-output ignition coil for a drone engine. It adopts a closed magnetic circuit structure and a combination of iron core adsorbed by magnetic sheets to increase the energy storage of the primary coil, and improves the stability by coating the coil assembly with epoxy resin.
Benefits of technology
It improves ignition energy, reduces the number of spark plugs, lowers the overall weight, and ensures the normal operation of other cylinders in the event of a coil failure, thereby enhancing the safety and reliability of the drone.

Abstract
An unmanned aerial vehicle engine grouping ignition coil comprises a shell, the shell is provided with a containing cavity with an upward opening, the containing cavity is covered with a top cover, the bottom of the shell protrudes towards the two sides in the transverse direction to form a first high-voltage head and a second high-voltage head, a low-voltage head is installed on one side of the shell, and the low-voltage head is installed on the other side of the shell. A coil assembly is installed in the containing cavity and provided with a positive high-voltage output end and a negative high-voltage output end, a first high-voltage wire harness is installed on the first high-voltage head, and the other end of the first high-voltage wire harness is used for being provided with a first spark plug connected to the positive high-voltage output end. A second high-voltage wire harness is installed on the second high-voltage head, and the other end of the second high-voltage wire harness is used for configuring a second spark plug connected to the negative high-voltage output end. The structure optimization design of the ignition coil is a single-coil double-output structure, one coil can be a two-cylinder ignition coil, and the ignition energy is improved. For the unmanned aerial vehicle, the number of spark plugs used for single-coil dual output is reduced by half, and the total weight is reduced.
