The utility model provides a night search and rescue lighting device of a rescue helicopter, and belongs to the technical field of lighting devices. Comprising an illuminating lamp; the horizontal vibration reduction assembly is arranged at the top of the illuminating lamp and comprises a base arranged at the top of the illuminating lamp, a connecting shaft is arranged between the base and the illuminating lamp, the connecting shaft is fixedly connected with the illuminating lamp, and a transmission plate is fixedly connected to the end, close to the interior of the base, of the connecting shaft; a main elastic piece is arranged on the side, close to the transmission plate, of the base. By arranging the horizontal vibration reduction assembly, when the illuminating lamp is disturbed by airflow, the connecting shaft swings along with the illuminating lamp, then the transmission plate is driven to move in the base, the acting force borne by the transmission plate is transmitted to the main elastic pieces, and the multiple main elastic pieces can conduct vibration reduction by means of elastic deformation of the main elastic pieces. The vibration energy can be effectively absorbed and buffered from multiple directions, the influence of vibration in the horizontal direction on the lighting device is remarkably reduced, and the service life of the lighting device can be prolonged.

The utility model discloses a vibration reduction electric toothbrush, and relates to the technical field of electric toothbrushes. The electric toothbrush comprises a toothbrush body and a toothbrush head detachably connected with the toothbrush body, the toothbrush body comprises a shell, a charging assembly, a battery assembly, a motor assembly and a machine body support. The interior of the machine body support is divided into a first containing area, a second containing area and a third containing area through a first partition plate and a second partition plate, and the charging assembly, the battery assembly and the motor assembly are arranged in the first containing area, the second containing area and the third containing area respectively. The motor assembly comprises a motor and a wrapping piece, and the motor is wrapped by the wrapping piece and then placed in the third containing area. Due to the arrangement of the wrapping pieces in the machine body support and the motor assembly, resonance borne by all the assemblies and the shell can be greatly reduced, the vibration reduction effect is high, the service life of all the assemblies is prolonged, and meanwhile the use experience of a user is improved.
