Description

Manual car hard disk damping fixing device and vehicle hard disk device

[I] Technical field

[2] The present invention relates to the field of shock absorption and anti-vibration technology, and in particular to a vehicle-mounted hard disk damping fixture and a vehicle-mounted hard disk device.

[3] Background Art

[4] The development of hard disk technology has made the application of hard disks more and more. Moreover, with the ability of hard disks to be stored in large quantities, it is bound to replace other storage devices in many fields. As we all know, the audio and video playback systems used in previous cars are based on tapes, video tapes or discs. The playback tools required for such storage media are complex in structure and poor in seismic resistance. The vibration on the car tends to be large, so the playback effect is often unsatisfactory. After the development of hard disk technology, many people have thought of using the hard disk as a storage medium for car audio and video systems, and developed a related playback system. For example, the application number is 02151272.8

The Chinese patent discloses a car hard disk playback system, including a hard disk and a decoder board. However, the patent ignores the important point that the existing hard disk has poor seismic resistance. If it is simply applied to the car hard disk playback system, if the hard disk is not used for shock absorption, it is easy to read data unstable, even Damaged hard drive
