4results about How to "Effective vibration reduction" patented technology

This invention provides an electronic device comprising a housing, a hard disk, at least one fan, and at least one vibration damping structure. The hard disk is disposed within the housing. At least one fan is disposed within the housing. At least one vibration damping structure is located between the hard disk and the at least one fan, and includes an elastic element and a mass block. The elastic element includes a mounting portion, a supporting portion, and a swinging portion. The mounting portion is disposed within the housing. The opposite ends of the supporting portion are respectively connected to the mounting portion and the swinging portion. The mounting portion and the swinging portion are located on the same side of the supporting portion. The swinging portion is oscillating relative to the supporting portion and the mounting portion. The mass block is disposed within the swinging portion. The solution provided by this invention enables the vibration damping structure to achieve both low assembly cost and effective vibration damping.

The invention provides an electronic device. The electronic device comprises a machine shell, a hard disk, at least one fan and at least one vibration reduction structure. The hard disk is arranged in the case. The at least one fan is arranged in the machine shell. The at least one damping structure is located between the hard disk and the at least one fan and comprises an elastic piece, a first mass block, at least one compression spring and at least one second mass block. The elastic sheet comprises two mounting parts and a bending part. The two installation parts are installed on the machine shell. The two opposite ends of the bending part are connected to the two installation parts respectively. The distance between the middle section of the bending part and the casing is larger than the distance between the two opposite ends of the bending part and the casing. The first mass block is arranged at the middle section of the bending part. One end of at least one compression spring is arranged on one of the two mounting parts. One end of the at least one second mass block is connected to the other end of the at least one compression spring. According to the vibration reduction structure, the low assembly cost and the vibration reduction effect can be achieved at the same time.

The application provides an impact-resistant damper. The impact-resistant damper comprises an eddy current damping unit and a buffer damping unit. The eddy current damping unit comprises a ball screw drivingly connected with a controlled structure and a fixed outer sleeve arranged outside the ball screw. The buffer damping unit comprises a resilient stiffness member arranged close to a driving connection end of the ball screw. One end of the resilient stiffness member is sleeved outside a screw rod of the ball screw, and the other end of the resilient stiffness member is connected with the outer sleeve. When the controlled structure reaches a preset displacement value or a preset impact value, one end of the resilient stiffness member is deformed to start the buffer damping unit. The application has the advantages of guaranteeing the vibration reduction and impact resistance effect of the controlled structure under large displacement and impact, compact structure and the like.

The utility model discloses a kind of damping devices for rotating parts, including shell and the base connected with shell lower end, damping liquid is contained in shell, sealing body is equipped in shell upper center position, rotating shaft is rotationally connected in the center position of shell upper portion, damping plate is fixedly connected in the lower end of rotating shaft, the lower portion of damping plate is fixedly connected with the damping piece of several radial directions along damping plate, the upper portion of base is fixedly provided with the fixed piece of several staggered settings with damping piece. The utility model and through damping piece and damping plate reduce the speed of rotating shaft, complete the damping vibration reduction effect, and change the original friction damping into the damping mode of high viscosity liquid, completely eliminate the wear of damping original piece, reduce the high temperature generated by friction, improve the service life of damper and rotating part, and avoid the problem that rotating part generates vibration, can effectively reduce the vibration of rotating part.
