4results about How to "Improve vibration damping ability" patented technology

The foot pad comprises a vibration reduction body installed on a shell, the vibration reduction body comprises a first-stage vibration reduction face and a second-stage vibration reduction face, the shell is provided with a first contact face and a second contact face, the first-stage vibration reduction face abuts against the first contact face, and the second-stage vibration reduction face has an initial state and an abutting state abutting against the second contact face. In the initial state, a vibration reduction gap exists between the second-stage vibration reduction face and the second contact face. The water purifier comprises a shell and a foot pad arranged at the bottom of the shell. The foot pad comprises the vibration reduction body provided with the first-stage vibration reduction face and the second-stage vibration reduction face, when the shell is subjected to vibration and transmits vibration to the vibration reduction body, the vibration is transmitted to the vibration reduction body through the first contact face and the first-stage vibration reduction face which abut against each other, the vibration is subjected to kinetic energy reduction in the transmission process, preliminary vibration reduction is achieved, and the vibration reduction effect is improved. Along with continuous vibration, the first-stage vibration reduction face is stressed and compressed to deform, so that the second contact face abuts against the second-stage vibration reduction face, and vibration is greatly weakened.

The automatic inflation manned airbag comprises a main body, a connecting rod, a rotor wing, a fixing device, the automatic inflation manned airbag and an inflation device, and the main body is connected with the rotor wing through the connecting rod; the body is connected with the automatic inflation manned air bag through the fixing device, the automatic inflation manned air bag comprises an inner shell and an outer soft shell, the outer soft shell is arranged on the outer side of the inner shell in a sleeving mode to form an air storage cavity, and the inflation device is used for inflating the air storage cavity. According to the technical scheme, when the unmanned aerial vehicle needs to throw personnel or goods in a complex terrain or an area where the unmanned aerial vehicle is difficult to land, the throwing and transporting device is directly used, and the inner shell and the outer soft shell of the throwing and transporting device form the air storage cavity, so that the air bag is formed; the air bag damping technology depends on compression and deformation of the air bag to absorb and disperse impact energy generated when the unmanned aerial vehicle throws goods to achieve a strong damping effect, and the manufacturing and maintenance cost of the air bag is relatively low.

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.
