4results about How to "Avoid crash noise" patented technology

The application discloses a wireless charging module with a charging main body and a fan, and the charging main body at least comprises a sheet metal bottom shell and a main body air duct; the sheet metal bottom shell is located at the bottom of the charging main body; the fan at least comprises a fan shell, a fan blade group and a fan air duct; the fan shell is fixed on the sheet metal bottom shell, and the fan blade group is arranged in the fan shell; in the axial direction, the fan blade group directly faces the sheet metal bottom shell, and a gap is formed between the fan blade group and the sheet metal bottom shell; the fan air duct and the main body air duct are communicated. The application effectively reduces the assembly process, reduces the total weight and total cost of the product, and avoids the generation of collision noise.

The utility model discloses an anti-shake long-size titanium container vacuum structure which comprises a vacuum structure body formed by welding an inner container and an outer container, a buffer assembly is arranged in the vacuum structure body, and the buffer assembly is installed on the outer wall of the inner container or the inner wall of the outer container and used for preventing the inner container and the outer container from colliding. According to the anti-shaking long-size titanium container vacuum structure, the buffer assembly is arranged between the inner container and the outer container of the cup body, collision between the inner container and the outer container can be avoided, collision noise is avoided, and the service life of the titanium cup can be prolonged.

The application relates to the technical field of dry transformers, and particularly discloses an amorphous alloy dry transformer with a double-layer shell structure, which comprises a mounting box body, a damping pad is fixedly connected to the bottom of the mounting box body through a support, a rain shelter is fixedly connected to the top of the mounting box body through a support, cooling devices are fixedly connected to the two sides of the mounting box body, and a transformer body is fixedly connected to the bottom of the mounting box body through a damping device. The amorphous alloy dry transformer with the double-layer shell structure is provided with the damping device, can absorb most of the vertical and horizontal vibrations generated during the operation of the transformer, and can automatically clean dust on the air inlet of the cooling device and scatter and agitate the drying agent by using the weakened slight vibration, so that the cooling and ventilation effect is improved.

This utility model provides a bathroom cabinet drawer buffer slide structure, belonging to the technical field of furniture hardware accessories. It includes a cabinet frame and a drawer body, which are detachably connected. An outer rail assembly is provided on the inner side of the cabinet frame, and an inner rail assembly is provided on the outer side of the drawer body. Through the outer rail assembly, this utility model enables a retractable damper and spring-assisted slider to move with the inner rail. When the drawer body is pushed in to its final stroke, the damper is triggered, the piston is compressed, and internal oil flows slowly through small channels, creating resistance and gradually reducing the drawer body's speed to a standstill. The inner rail assembly enables a meshing plastic rack and pinion to effectively improve the stability of the inner rail and drawer body during movement. Therefore, this structure provides a buffer function when the drawer body is pulled out or pushed in, and avoids collision noise when closing.
