The data storage device is further described below. Specifically, referring to fig. 1 to 3, fig. 1 is an exploded view of a data storage device according to the present application, fig. 3 is an exploded view of the data storage device in fig. 1, and fig. 3 is a cross-sectional view of the data storage device in fig. 1. As shown in fig. 1, the data storage device includes a lid 201, a sealing lid 202, an electronic device 203, a case 204, and a case 205. The lid 201 and the housing 205 may be combined to form a case of the data storage device. The cartridge provides outermost physical protection for the data storage device. The cover 201 and the housing 205 may be fixedly connected by bolts, and as shown in fig. 1, corresponding screw holes are provided on the side edges of the cover 201 and the housing 205, so as to fixedly connect the cover 201 and the housing 205. It is understood that the cover 201 and the housing 205 may also be fixedly connected by other methods, such as welding or snapping, which are not limited herein. The box cover 201 and the housing 205 are provided with reinforcing ribs to enhance the impact bearing capability of the box cover 201 and the housing 205 and prevent deformation thereof. Specifically, as shown in fig. 1, a strip-shaped reinforcing rib is disposed on the box cover 201, and a U-shaped reinforcing rib is disposed on the housing 205.

The box body is internally provided with a sealing cover 202, an electronic device 203 and a box body 204, wherein the sealing cover 202 and the box body 204 can be combined into a sealing box. A heat-resistant sealing ring 209, which may be a high-temperature-resistant sealing rubber ring, is disposed around the outside of the tank opening of the tank body 204. The sealing cover 202 is sleeved on the outer side of the heat-resistant sealing ring 209 to be tightly connected with the box body 204. The heat-resistant sealing ring 209 can play both the role of fire prevention and the role of water prevention, and at the same time, the connection between the sealing cover 202 and the box 204 is more tight. The sealing lid 202 and the case 204 are also provided with ribs to prevent deformation of the sealing case upon impact, thereby further protecting the internal electronic devices. As shown in fig. 3, a heat insulating material 401 is filled between the sealed box and the box body, the heat insulating material completely covers the sealed box, and fills the space between the sealed box and the box body. Thus, when the box body is in a high-temperature environment such as a fire, the heat-insulating material separates the high-temperature environment from the sealing box so as to protect the electronic devices inside from being damaged by high temperature.

The electronic device 203 is disposed inside the sealed case. Typically, the electronic device 203 is embodied as a memory for data storage, e.g., an eMMC memory. The electronic devices 203 may also include other types of electronic devices such as processors and caches. It will be appreciated that any electronic device to be protected may be disposed within the enclosure for protection, and the size of the enclosure and the case may be determined by the size of the type of electronic device to be protected, and therefore, there is no limitation on the type of electronic device and the size of the enclosure and the case. As shown in fig. 1, a data transmission line 206 is connected to the electronic device 203. Specifically, the electronic device 203 is an eMMC memory, and the data transmission line 206 is directly connected to the electronic device 203 through a data transmission interface. In one embodiment, the electronics 203 are connected to the data transmission line 206 using a 4-bit interface. A filter capacitor and an energy storage capacitor may also be included in the electronic device 203. Under the abnormal conditions of vehicle accidents and the like, the power supply of the electronic device 203 is unstable, and the filter capacitor and the energy storage capacitor can output smooth direct current output for the electronic device 203, so that the electronic device 203 is prevented from being affected by unstable current to cause faults. The electronic device 203 may be powered using a 3.3V ± 5% power supply. The electronics 203 may also be controlled using a separate switching circuit. When an accident occurs, the controller can directly turn off the electronic device 203 through an independent switch circuit, so that damage or data loss caused by continuous operation of the electronic device in the accident process is avoided.

Referring to fig. 3, the electronic device 203 and the sealed case are filled with a heat absorbing material 406 based on a chemical reaction. Specifically, the heat insulating material completely encases the electronic device therein, and fills the space between the electronic device and the sealing case. When the data storage device is in a high-temperature environment such as a fire, and the like, for the heat which cannot be completely isolated by the heat insulating material, the heat absorbing material will generate chemical reaction when the temperature rises and absorb the heat, thereby ensuring that the electronic devices in the data storage device are not influenced by the high temperature.

The data transmission line 206 extends outside the case through the heat absorbing material and the heat insulating material. Specifically, as shown in fig. 2 and 3, wiring holes 301 are formed in the side walls of the sealing box and the box body. The data transmission line 206 protrudes out of the box body through the wiring hole 301. There are vias in the heat sink material and the insulating material for the data transmission line 206 to pass through. The wiring holes on the closure and the wiring holes 301 on the cassette are offset from each other so that the passage in the insulating material 401 will have at least one bend to communicate the wiring holes on the closure with the wiring holes 301 on the cassette. Thus, the data transmission line 206 will also bend with the via as it extends out of the cassette along the via. Therefore, when the data storage device is in a high-temperature environment, because the energy of the heat radiation is radiated outwards linearly, the heat radiation received by the data transmission line behind the bending part is greatly reduced, and the heat cannot reach the electronic device along the data transmission line, so that the protection capability of the electronic device is improved.

The data transmission line 206 is provided with a transmission interface for reading and writing data. Through which devices external to the data storage device operate the electronics 203 within the data storage device, e.g., read and write operations or data transfer. In the present embodiment, as shown in fig. 1, a first transmission interface 207 and a second transmission interface 208 are disposed on the data transmission line 206, and the functions of the two transmission interfaces are the same. The first transmission interface 207 is located at the end of the data line that protrudes out of the wiring hole, and the second transmission interface 208 is located adjacent to the electronic device 203. Specifically, the second transmission interface 208 may be disposed between the bending portion of the data transmission line 206 bent along the path and the electronic device. In a conventional case, a device external to the data storage device communicates with the electronic device 203 through the first transmission interface 207. When the data storage device is affected by fire or the like, the data transmission lines extending out of the case and a portion of the data transmission lines in the path of the heat insulating material may be burned to disable reading of data through the first transmission interface 207, and at this time, the data transmission lines may be further pulled out of the case, and the second transmission interface 208 is exposed outside the case as the data transmission lines move outward, so that direct communication may be performed without disassembling the case. Thus, further damage to the electronic device which may be caused when the cartridge is disassembled can be avoided, thereby improving the safety of the data storage device.

It will be understood that the specific location of the second transmission interface may depend on the location of the bend of the passage and the size of the data storage device, for example, the second transmission interface may be located outside or inside the sealed box, or may be directly located on the data transmission line in the bend, which is not limited herein. When the second transmission interface is needed, in addition to the above manner, the second transmission interface may be directly exposed or pulled out from the sealed box by only disassembling the box body and removing the heat insulating material without disassembling the sealed box, and how to expose the second transmission interface is not limited herein.

Referring to fig. 3, in this embodiment, the data storage device may further include a sealed inner container 403. The sealing liner 403 is disposed inside the sealing box and is used for accommodating the electronic device 203. The sealed liner can separate the electronic device 203 from the heat sink material 406 to prevent the heat sink material from contaminating or corroding the electronic device 203, thereby extending the life of the electronic device 203.

In this embodiment, the electronic device 203 may further include a circuit protection layer. The circuit protection layer is disposed against the circuit board of the electronic device and inside the sealed inner container 403. Specifically, as shown in fig. 3, the circuit protection layer 404 covers the body of the electronic device 203 and fills the sealed inner container 403. In embodiments where a sealed inner container is not present, the circuit shield 404 may be in direct contact with the heat sink material 406. The circuit protective layer can be made of materials such as ink, silica gel or epoxy resin and the like so as to protect the electronic device in the installation and manufacturing process of the data storage device, and meanwhile, the strength of the electronic device 203 can be improved, and the impact resistance of the electronic device can be further enhanced.

Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the application and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains.

It will be understood that the present application is not limited to the precise arrangements described above and shown in the drawings and that various modifications and changes may be made without departing from the scope thereof. The scope of the application is limited only by the appended claims.
