DETAILED DESCRIPTION

[0044] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be more comprehensive and complete and fully convey the concept of the example embodiments to those skilled in the art.

[0045] See also Figures 1 to 3 as well as Figures 12 to 17As shown, the present application provides a data protection device, which can be used in automobiles, airplanes, and ships. For example, a car may have a traffic accident while driving, an airplane may have a flight accident while flying, and similarly, a ship may have a navigation accident while sailing on the water. In order to accurately analyze the specific occurrence process of these accidents, a storage chip 100 can be set on such vehicles, and the driving parameters of the vehicle can be saved through the storage chip 100. In order to reduce the damage to the storage chip 100 when an accident occurs. The data protection device of the present application includes: a storage chip 100, a protective cover 200, a protective shell 300 and an outer shell 400.

[0046] The memory chip 100 is used to store data; the memory chip 100 is provided with a storage unit, and the storage unit can save data.

[0047] In the direction away from the memory chip 100, the protective cover 200, the protective shell 300 and the outer shell 400 are sequentially arranged around the memory chip 100, and it can be seen that three layers of protection measures are formed around the periphery of the memory chip 100. One end of the protective cover 200 has an opening 201, one end of the protective shell 300 is provided with a wire opening 303, and one end of the outer shell 400 is provided with a wire opening 401. The opening 201 of the protective cover 200, the wire opening 303 of the protective shell 300 and the wire opening 401 of the outer shell 400 are arranged relatively; the data protection device also includes a data line 110, one end of the data line 110 is sequentially passed through the wire opening 401, the wire opening 303 and the opening 201, and is connected to the memory chip 100, and the other end of the data line 110 extends and protrudes from the surface of the outer shell 400. The wire opening 401, the wire opening 303 and the opening 201 can be arranged directly opposite to each other, or they can be staggered at a certain distance from each other. The data line 110 can transmit data bidirectionally, and can transmit data to the memory chip 100 or download data.

[0048] In this embodiment, external signals can be transmitted to the memory chip 100 through the data line 110, and data in the memory chip 100 can also be downloaded through the data line 110. A protective cover 200, a protective shell 300 and an outer shell 400 are respectively arranged on the periphery of the memory chip 100. The protective cover 200, the protective shell 300 and the outer shell 400 form layer-by-layer protection measures for the memory chip 100, effectively protecting the chip storing data, reducing the impact on the chip, and enabling the chip to provide as complete data as possible, so as to facilitate the analysis of the cause of the accident.

[0049] The protective cover 200, the protective shell 300 and the outer shell 400 are all made of metal, which has strong structural stability and can provide strong support and protection for the memory chip 100. Moreover, metal is heat-conductive and can dissipate the heat of the memory chip 100 as quickly as possible.

[0050] See again Figure 1 As shown, in one embodiment of the present application, the data line 110 further includes a plurality of gold fingers 111 for downloading data, and the plurality of gold fingers 111 are arranged at intervals in the extending direction of the data line 110. The gold finger 111 is a hardware structure, and is usually composed of a plurality of conductive contacts, and is called a gold finger 111 because its surface is plated with gold and the conductive contacts are arranged like fingers. The gold finger 111 is actually a layer of gold coated on the copper clad board through an electroplating process, because gold has a strong anti-oxidation property and can protect the internal circuit from corrosion.

[0051] When an accident occurs, the data line 110 may be damaged, such as broken. At this time, the position of the golden finger 111 can be cut to remove the damaged data line 110, and the data can be directly downloaded and read at the position of the golden finger 111.

[0052] During the process of setting up the data line 110 , it is inevitable that there are some bends at the positions, and these bends are more likely to be damaged when they are impacted. Therefore, gold fingers 111 may be set at the bends of the data line 110 .

[0053] For another example, the protection of the data transmission line by the setting of the protective cover 200, the protective shell 300 and the outer shell 400 is divided into multiple different protection zones, with layers of protection from the inside to the outside, and a gold finger 111 can be set at each different protection zone. The position of each protection zone is relatively isolated, and even if the data line 110 near the outside is damaged, the position of the gold finger 111 inside can still be used.

[0054] Furthermore, the data protection device further includes an insulating protective layer, which is arranged around the gold finger 111. The insulating protective layer can provide insulating protection for the gold finger 111, preventing the gold finger 111 from being directly exposed to the outside, and can also reduce the line short circuit caused by the gold finger 111 during the data transmission process, thereby ensuring normal data transmission. The insulating protective layer also protrudes from the surface of the data line 110, making it easier to distinguish the position of the gold finger 111.

[0055] The data protection device also includes a reinforcing sheet 120. The reinforcing sheet 120 mainly plays a supporting role. The memory chip 100 is arranged on the reinforcing sheet 120. The reinforcing sheet 120 can provide certain support and protection for the memory chip 100, improve the overall strength of the memory chip 100, and reduce the damage of the memory chip 100. The reinforcing sheet 120 is usually a metal sheet with high strength, and can also be a plastic sheet with high strength.

[0056] When the reinforcing sheet 120 is a metal sheet, it also has a certain heat dissipation effect. The heat generated by the memory chip 100 can be transferred to the reinforcing sheet 120 and then dissipated through the surface of the reinforcing sheet 120 .

[0057] The data cable 110 will also generate a certain amount of heat when transmitting data. In order to improve the heat dissipation effect of the data cable 110, in one of the embodiments of the present application, the protective shell 300 and the outer shell 400 are arranged at intervals, and the data cable 110 is bent at the positions of the wire passing port 303 and the wire passing port 401, respectively, and the data cable 110 is respectively attached to the surfaces of the protective shell 300 and the outer shell 400.

[0058] More specifically, the data line 110 can be attached to the outer surface of the protective shell 300 or the inner surface of the outer shell 400, so that surface-to-surface contact can be achieved, and the contact between the data line 110 and the outer surface of the protective shell 300 and the inner surface of the outer shell 400 is increased, and the heat generated by the data line 110 can be directly transferred to the protective shell 300 and the outer shell 400. The outer shell 400 is provided with a recessed portion 404, which protrudes toward the inside of the outer shell 400, and the data line 110 can be attached to the recessed portion 404 of the outer shell 400.

[0059] When an accident occurs or it rains, water may enter the protective cover 200, causing the memory chip 100 to be soaked in water, resulting in failure of the memory chip 100. To this end, in one embodiment of the present application, the data protection device further includes a sealing cover 500, which is disposed at the opening 201 of the protective cover 200 and is sleeved on the outer periphery of the data line 110.

[0060] The sealing sleeve 500 can be sealed at the opening 201 of the protective sleeve 200, and plays a role in sealing the gap between the data cable 110 and the protective sleeve 200, thereby reducing the occurrence of water intrusion. The sealing sleeve 500 can be made of rubber, and the sealing sleeve 500 fits between the protective sleeve 200 and the surface of the data cable 110. The sealing sleeve 500 can also have a certain elasticity, so that it is tightly pressed between the inner wall surface of the protective sleeve 200 and the outer surface of the data cable 110. More specifically, the data cable 110 can pass through the center of the sealing sleeve 500, so that the pressure on the data cable 110 from all sides is basically equal.

[0061] See also Figure 2 and Figure 6 As shown, in one embodiment of the present application, the data protection device further includes a heat sink 210, which is connected to the surface of the protective cover 200 and has heat dissipation holes 211. The heat of the protective cover 200 can be transferred to the heat sink 210, and the provision of the heat dissipation holes 211 is equivalent to increasing the contact area between the heat sink 210 and the surrounding air, thereby increasing the heat dissipation effect.

[0062] See also Fig.10 and Fig.11 As shown, in one embodiment of the present application, the data protection device further includes a cover plate 600, which is disposed on the surface of the protective shell 300. A reinforcing strip 610 is disposed on the cover plate 600, and a plurality of reinforcing strips 610 are disposed. The plurality of reinforcing strips 610 are protruded and arranged on the surface of the cover plate 600, and the protruding direction of the reinforcing strip 610 faces away from the protective shell 300, and an air flow channel 620 for air circulation is formed between the reinforcing strip 610 and the protective shell 300. The heat transferred to the protective shell 300 can be dissipated through the air flow channel 620, thereby increasing the air contact surface between the protective shell 300 and the outside world.

[0063] Two cover plates 600 may be provided, which are respectively provided on the upper surface and the lower surface of the protective shell 300 . The structural strength of the protective shell 300 is increased by providing the cover plates 600 .

[0064] As for the arrangement of the reinforcing strips 610, three reinforcing strips 610 may be arranged, and the distance between the reinforcing strip 610 in the middle position and the reinforcing strips 610 on the left and right sides is equal. By arranging the reinforcing strips 610 in sequence at equal intervals, the balance of the overall structure is further improved. In other words, the reinforcing strips 610 are evenly distributed on the surface of the cover plate 600, so that the cover plate 600 can withstand the same impact force in multiple directions.

[0065] In addition, the extension directions of at least two of the plurality of reinforcing strips 610 may be cross-arranged. As can be seen, the extension directions of at least two reinforcing strips 610 are different, so that the support strength can be improved in two different directions. For example, one reinforcing strip 610 extends horizontally, and the other reinforcing strip 610 extends longitudinally, and the extension directions of the two reinforcing strips 610 are orthogonal.

[0066] See also Figures 4 to 7 As shown, in one embodiment of the present application, the protective shell 300 is arranged to form a storage space 301, the protective cover 200 is arranged in the storage space 301, the protective shell 300 has a through hole 302, the through hole 302 is connected to the storage space 301, and the data protection device also includes a heat absorbing medium, and the heat absorbing medium is injected into the storage space 301 through the through hole 302.

[0067] There may be two through holes 302, which are respectively located on the upper surface and the lower surface of the protective shell 300, and the two through holes 302 are located at diagonal positions of the protective shell 300. Some heat absorbing medium can be filled into the storage space 301 through the through holes 302, and the heat absorbing medium can contact the protective cover 200 and absorb the heat of the protective cover 200. Through the injection of the heat absorbing medium, the heat of the protective cover 200 can be transferred to the protective shell 300 more quickly.

[0068] The protective shell 300 further includes a sawtooth piece, which can be arranged around the through hole 302. In addition, in order to improve the sealing effect of the protective shell 300, a sealing film can be arranged on the through hole 302 to prevent external water vapor from entering the storage space 301 through the through hole 302.

[0069] See also Fig.13 and Fig.14 As shown, the outer surface of the data line 110 includes a shielding layer, the shielding layer includes shielding wires, and a plurality of shielding wires are provided. The shielding wires can shield external signals and reduce interference with internal signals of the cable. There are at least two arrangements of the shielding wires. The first arrangement is that the shielding wires are distributed in parallel on the outer surface of the cable. The extension direction of the shield is the same as the extension direction of the cable. The second arrangement is that the shielding wires are cross-arranged on the outer surface of the cable, and the shielding wires can cross to form a grid.

[0070] See also Fig.15 As shown, in one embodiment of the present application, the data protection device further includes a reinforcing rib 700 , and at least one of the protective shell 300 and the outer shell 400 is provided with the reinforcing rib 700 .

[0071] The reinforcing rib 700 can be provided on the protective shell 300, or on the outer shell 400, or the reinforcing rib 700 can be provided on the protective shell 300 and the outer shell 400 respectively. In this embodiment, the protective shell 300 and the outer shell 400 can withstand a certain impact force. On this basis, the reinforcing rib 700 is further provided on the protective shell 300 and the outer shell 400. The provision of the reinforcing rib 700 can improve the structural strength of the protective shell 300 and the outer shell 400. When impacted, the structural stability can be better maintained, deformation can be reduced, and more favorable protection can be provided for the memory chip 100.

[0072] In addition, by providing the reinforcing ribs 700, the surface areas of the protective shell 300 and the outer shell 400 are increased, thereby increasing the heat dissipation effect of the protective shell 300 and the outer shell 400, and further improving the heat dissipation effect of the memory chip 100. The reinforcing ribs 700 can be arranged in parallel on the protective shell 300 or the outer shell 400, or can be cross-arranged on the protective shell 300 or the outer shell 400. The arrangement density of the reinforcing ribs 700 can also be adjusted according to the position that may be squeezed, for example, the arrangement density of the reinforcing ribs 700 can be increased at the position with large force.

[0073] In one embodiment of the present application, the data protection device further includes a card sleeve 800, and the card sleeve 800 is arranged at the wire opening 401 of the housing 400. The housing 400 includes a first shell 410 and a second shell 420. For the arrangement of the wire opening 401, a first notch is provided on the side wall of the first shell 410, and a second notch is provided on the side wall of the second shell 420 facing the first notch, and the first notch and the second notch are opposite to form the wire opening 401.

[0074] See also Figure 8 and Fig. 9 As shown, the ferrule 800 is generally made of rubber. When the cable opening 401 is composed of a first notch and a second notch, the ferrule 800 can also be divided into two half circles, namely a first half circle 810 and a second half circle 820. The first half circle 810 is arranged at the first notch, and the second half circle 820 is arranged at the second notch. The first half circle 810 and the second half circle 820 can be buckled together, and a gap is formed between the first half circle 810 and the second half circle 820 to ensure that the data line 110 can pass through.

[0075] In addition, the cable port 401 may be separately provided on the second housing 420, or separately provided on the first housing 410. In short, the ferrule 800 may be complete and the ferrule 800 may be separately embedded in the cable port 401. The friction between the data cable 110 and the cable port 401 is reduced.

[0076] See also Figures 17 to 19 As shown, in one embodiment of the present application, the data protection device also includes a fixing member 900, and the housing 400 is provided with a fixing hole 402, and the fixing member 900 is arranged in the fixing hole 402 to fix the housing 400. The fixing member 900 has a certain sealing effect. For example, the fixing member 900 is a sealing threaded column, and a threaded hole 910 is provided in the middle of the sealing threaded column. The sealing threaded column is fixed in the fixing hole 402, and the threaded hole 910 of the sealing threaded column is used to connect with external facilities. The sealing threaded column can be welded in the fixing hole 402, or fixed in the fixing hole 402 by means of sealing adhesive bonding. When connecting to external facilities, screws can be used, one end of the screw is connected to the threaded hole 910 of the sealing threaded column, and the other end of the screw is connected to the external facility.

[0077] It should be noted that the bottom end of the threaded hole 910 is sealed to prevent rainwater from penetrating into the interior of the housing 400 along the threaded hole 910. Four fixing members 900 may be provided, and the four fixing members 900 may be distributed on the same surface of the housing 400 at equal intervals.

[0078] A heat dissipation groove 403 may also be provided on the surface of the first housing 410, and the contact area between the first housing 410 and the air may be increased through the heat dissipation groove 403. Generally, the heat generated by the memory chip 100 is first transferred to the protective cover 200, then to the protective shell 300, and finally to the outer shell 400. By providing the heat dissipation groove 403 on the first housing 410, the heat of the outer shell 400 may be dissipated into the surrounding air as quickly as possible, thereby reducing the accumulation of heat on the outer shell 400. A plurality of heat dissipation grooves 403 may be provided, and the plurality of heat dissipation grooves 403 may be provided in parallel.

[0079] In addition, a heat dissipation slot 403 may be provided on the protective shell 300 to improve the heat dissipation effect of the protective shell 300.
