With the development of technology, hybrid power has become a good choice for UAV power systems. During the installation of hybrid power systems of UAVs, special fixed support accessories are required for auxiliary support. During the use of hybrid power systems, they will inevitably vibrate repeatedly when overturned or shaken, which seriously restricts the efficiency of the accessories and even affects the normal operation of the hybrid power system. This requires special shock absorbing equipment for auxiliary support, but traditional shock absorbing equipment has many problems and cannot fix the hybrid power system. The quick threaded installation of the system and the mounting plate, as well as the mounting plate and the external supporting plate frame, cannot achieve all-round elastic buffering and shock absorption of the mounting plate, cannot achieve side reinforcement of the oil-electric hybrid power system, the system is easy to deviate, and elastic contact cannot be guaranteed during the reinforcement process, and the shock absorption effect cannot be achieved. It is impossible to achieve elastic buffering and shock absorption when the bottom and side of the plate frame contact with the installation part, thereby failing to ensure all-round shock absorption and buffering of the oil-electric hybrid power system and the supporting frame. The operating efficiency of each component is severely restricted, the service life of the accessories is reduced, and the use efficiency of the shock absorbing device is low.
