Description

Technical Field

[0001] The present invention relates to the technical field of storage devices, and in particular to a portable fast-pluggable data storage medium. Background Art

[0002] The currently known data storage body inside the host is to encapsulate the hard disk and data processing module in a sheet metal shell. There is a data interface on the back of the storage body and an aluminum alloy panel on the front. It is connected to the sheet metal shell by screws, and there are two hand-tightened screws on the left and right sides of the panel. When the storage body needs to be inserted into the chassis for operation, the storage shell is first pushed into the fixed frame cavity inside the host chassis; when the data interface of the storage body is connected to the data interface inside the host, it is tightened by two hand-tightened screws on the panel, so that the storage body can collect and store the data transmitted by the host. When the ship encounters an emergency or a major accident and needs to pull out the storage body, it is necessary to first loosen the two screws, and then pinch the screws by hand to pull them out, so as to pull out the storage body.

[0003] The data storage bodies currently on the market have the following problems.

[0004] Inconvenient plugging and unplugging. When the current data storage body is inserted into the chassis, there is a large friction between the storage body shell and the fixing bracket, and there is no positioning design on the back of the storage body, so the data interface between the data storage body and the host is easily misaligned when plugged in. The storage body needs to be fixed by the captive screws on the panel. At the same time, when the data storage body is to be unplugged, it is necessary to loosen the captive screws first, and then pinch the captive screws by hand to pull out the storage body, which can no longer meet the requirements of quick plugging and unplugging.

[0005] Low IP protection level. The current storage reinforcement shell, whether it is a sheet metal structure or an aluminum alloy structure, has a very low IP protection level and no pressure resistance. Once a ship is flooded or sinks, the data storage body will have water ingress problems. Even worse, the data storage body shell will be directly deformed, which will cause the data inside the storage body to be damaged.

[0006] Inconvenient to carry: After the current data storage medium is pulled out from the chassis, there is no portable strap or handle designed, which is very inconvenient to carry when a major accident or emergency escape occurs.

[0007] Therefore, the current navigation recorder data storage medium has the problems of no quick plug-in capability, low IP protection level and inconvenient portability. Summary of the invention

[0008] In view of this, the present invention provides a portable quick-plug data storage body, which can be used as the storage medium of a ship's navigation data recorder and installed in the host of the navigation data recorder to record and store navigation data in real time.
