[0043] 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.

[0044] See also Figure 1 and Fig.10 As shown, the present application provides a cover plate 100, which is used to be set on the surface of a protective shell 200. The protective shell 200 is surrounded by a storage space 201 for placing a memory chip 300. The memory chip 300 in the present application can be used in cars, airplanes, and ships. Traffic accidents may occur when cars are driving, and flight accidents may occur when airplanes are flying. Similarly, navigation accidents may occur when ships are sailing on the water. In order to accurately analyze the specific occurrence process of these accidents, a memory chip 300 can be set on such vehicles, and the driving parameters of the vehicles can be saved by the memory chip 300. A protective shell 200 can also be set around the memory chip 300 to provide protection for the memory chip 300. The cover plate 100 is set on the protective shell 200 to further improve the structural strength of the protective shell 200.

[0045] Specifically, the cover plate 100 includes: a plate body 110 and a reinforcing rib 120. The plate body 110 is arranged on the surface of the protective shell 200; a plurality of reinforcing ribs 120 are arranged, and a plurality of reinforcing ribs 120 are protruded and arranged on the surface of the plate body 110, and the protruding direction of the reinforcing rib 120 is facing away from the protective shell 200, and the reinforcing rib 120 is used to form an air flow channel 101 for air circulation between the protective shell 200. The plate body 110 can be integrally provided with the reinforcing rib 120, or the reinforcing rib 120 can be welded to the plate body 110 after the plate body 110 is manufactured. The plate body 110 can be a flat plate structure or a frame structure. In the case of a flat plate structure, the plate body 110 can fit tightly on the surface of the protective shell 200. When the plate body 110 is a frame structure, the plate body 110 can cover the protective shell 200, and a certain spacing space can be formed between a part of the plate body 110 and the protective shell 200.

[0046] Generally, the cover plate 100 is made of metal, which has strong supporting strength and can further improve the structural strength of the protective shell 200. In addition, the cover plate 100 can be a PI (Polyimide) board, a bakelite board, a fiberglass board, etc. The thickness of the cover plate 100 can be set according to the load or pressure.

[0047] In this embodiment, the storage chip 300 is placed in the storage space 201 of the protective shell 200. The cover plate 100 is arranged on the surface of the protective shell 200. The overall strength of the cover plate 100 is improved by the arrangement of the reinforcing ribs 120 on the plate body 110. When impacted, the cover plate 100 can withstand a larger impact force. The impact on the chip is reduced, so that the chip can provide as complete data as possible, which is convenient for completing the analysis of the cause of the accident.

[0048] The cover plate 100 and the protective shell 200 can be fixed by bonding the cover plate 100 to the protective shell 200, such as applying glue between the cover plate 100 and the protective shell 200, and then fixing the cover plate 100 to the protective shell 200. In addition, the cover plate 100 and the protective shell 200 can also be fixed together by wrapping an adhesive tape.

[0049] The protective shell 200 has multiple surfaces, and the cover plate 100 can be set on only one of the surfaces or on each surface. There can be multiple situations regarding the size of the surface of the corresponding protective shell 200 occupied by the cover plate 100. The following is a partial explanation of the application: The first situation is that the coverage area of ​​the cover plate 100 occupies the entire surface of the corresponding protective shell 200; that is, the cover plate 100 covers the entire surface of one surface of the protective shell 200.

[0050] The second situation is that the coverage area of ​​the cover plate 100 occupies half of the surface of the corresponding protective shell 200; in this case, there may be only one cover plate 100, or two cover plates 100 may be arranged on the same surface.

[0051] The third case is that the coverage area of ​​the cover plate 100 occupies one quarter of the surface of the corresponding protective shell 200. In this case, there may be only one cover plate 100, or more cover plates 100 may be provided. For example, four cover plates 100 may be provided. In addition, in the case where the protective shell 200 is provided with a through hole 210, only one cover plate 100 may be provided at the corresponding position of the through hole 210. Alternatively, the cover plate 100 occupies one third of the surface of the protective shell 200.

[0052] In the present application, there are at least two ways to set the rib 120 in a protruding direction. The first way may be that the rib 120 protrudes in a direction close to the protective shell 200. The second way may be that the rib 120 protrudes in a direction away from the protective shell 200. Alternatively, the rib 120 may protrude in both a direction close to the protective shell 200 and a direction away from the protective shell 200.

[0053] Furthermore, the cover plate 100 includes a plate body 110 and a plurality of reinforcing ribs 120. The plate body 110 is arranged on the surface of the protective shell 200 to form a flat reinforcing layer. The reinforcing ribs 120 are arranged on the surface of the plate body 110, presenting an outwardly protruding arrangement structure, and can also form an airflow channel 101 for air circulation. The memory chip 300 generates a large amount of heat when working. If this heat accumulates around the memory chip 300, it will reduce the working efficiency of the memory chip 300 and even burn the memory chip 300. Generally, the heat of the memory chip 300 will be transferred to the protective shell 200. If the cover plate 100 is in full contact with the protective shell 200, the contact surface between the protective shell 200 and the surrounding air medium will be reduced. Through the setting of the airflow channel 101, a certain distance can be spaced between the position of the reinforcing rib 120 and the surface of the protective shell 200. At this position, the surface of the protective shell 200 can be in direct contact with the air, thereby improving the heat dissipation effect of the protective shell 200 at this position. Furthermore, the air flow channel 101 is in communication with the air, and the heat of the protective shell 200 can be directly dissipated into the air.

[0054] There are many ways to set the reinforcing rib 120 in the present application, and the following examples illustrate the ways to set the reinforcing rib 120 respectively.

[0055] See also Figure 1 and Figure 2As shown, in the first arrangement of the reinforcing ribs 120 of the present application, a plurality of reinforcing ribs 120 are arranged in parallel. The reinforcing ribs 120 can run through the entire surface of the plate body 110, and the reinforcing ribs 120 are parallel to each other, so that the arrangement of the reinforcing ribs 120 is more regular as a whole. By arranging these reinforcing ribs 120 in parallel, the balance and stability of the structure are ensured, so that the reinforcing ribs 120 can improve the structural strength of the plate body 110 in a larger size range.

[0056] In the second arrangement of the reinforcing ribs 120 of the present application, the spacing distances between the multiple reinforcing ribs 120 are equal. For example, there are three reinforcing ribs 120, and the distance between the reinforcing ribs 120 in the middle position is equal to the distance between the reinforcing ribs 120 on the left and right sides. It is also possible to set a number greater than three, and the distances between two adjacent reinforcing ribs 120 are equal. In other words, the reinforcing ribs 120 are arranged in sequence at equal intervals, further improving the balance of the overall structure. In other words, the reinforcing ribs 120 are evenly distributed on the plate body 110, so that the plate body 110 can withstand the same impact force in multiple directions.

[0057] In addition, the distances between the multiple reinforcing ribs 120 may be different. For example, the density of the reinforcing ribs 120 increases gradually from one side to the other side of the plate body 110, or the density of the arrangement becomes looser. By adjusting the density of the arrangement of the reinforcing ribs 120, more reinforcing ribs 120 may be arranged for locations that may be subject to greater impact force, and fewer reinforcing ribs 120 may be arranged for locations that may be subject to less impact force, so that the locations where the reinforcing ribs 120 are arranged are more targeted.

[0058] More specifically, the densely arranged position may be toward the outside of the installation position of the protective shell 200. Generally, the outside of the protective shell 200 is subjected to a greater impact force, so that it can better play an impact-resistant role.

[0059] See also Figure 3 and Figure 4 As shown, in the third arrangement of the reinforcing ribs 120 of the present application, the extension directions of at least two reinforcing ribs 120 among the plurality of reinforcing ribs 120 are arranged crosswise. It can be seen that the extension directions of at least two reinforcing ribs 120 are different, so that the support strength can be improved in two different directions. For example, one reinforcing rib 120 extends horizontally, and the other reinforcing rib 120 extends longitudinally, and the extension directions of the two reinforcing ribs 120 are orthogonal.

[0060] In addition, reinforcing ribs 120 may be provided in more directions on the surface of the plate body 110, thereby improving the structural strength in more directions. For example, a plurality of reinforcing ribs 120 may cross to form a cross-shaped cross.

[0061] In the present application, the above three configurations of the reinforcing ribs 120 may be one of them, or a combination of the three structures of the reinforcing ribs 120. For example, a plurality of partitions are arranged on the surface of the plate body 110, and each partition is provided with a reinforcing rib 120 of one configuration.

[0062] See also Figure 5 and Figure 6 As shown, in one embodiment of the present application, the reinforcing rib 120 is an arc-shaped protrusion on the surface of the plate body 110, and the arc-shaped protrusion surface structure is smoother and has fewer corners, thereby distributing the pressure to various positions of the arc-shaped protrusion. By distributing the pressure structure, the positions where the pressure or stress is concentrated are reduced, and the situation of fracture at the position of the reinforcing rib 120 is reduced, thereby improving the structural strength of the cover plate 100.

[0063] Furthermore, in another embodiment of the present application, the protruding curvatures of the plurality of reinforcing ribs 120 are equal, the structure of each reinforcing rib 120 is basically the same, and the processing and manufacturing of the reinforcing ribs 120 are simple. In this way, the reinforcing ribs 120 can be manufactured uniformly, which facilitates the batch production of the reinforcing ribs 120 and improves efficiency when processing the cover plate 100.

[0064] In addition, the convex curvature of at least one reinforcing rib 120 may be smaller than the convex curvature of the other reinforcing ribs 120. The reinforcing ribs 120 are arranged into structures with different curvatures. Generally, the reinforcing ribs 120 with large curvatures can withstand greater impact forces. By setting the large and small curvatures of the reinforcing ribs 120, a combination of different curvatures can be formed. For different sizes and directions of impact forces, the structure of arranging the reinforcing ribs 120 is improved in a more targeted manner.

[0065] In one embodiment of the present application, the protective shell 200 is provided with a through hole 210, the plate body 110 forms a raised portion 130 at the position of the through hole 210, an airflow buffer space 131 is formed between the raised portion 130 and the surface of the protective shell 200, and the airflow channel 101 of the reinforcing rib 120 is connected to the airflow buffer space 131. The heat generated by the memory chip 300 can be dissipated through the through hole 210, and is fully in contact with the external ambient air in the airflow buffer space 131, thereby improving the heat dissipation efficiency.

[0066] A sealing film 500 may also be provided at the position of the through hole 210 . In this case, the through hole 210 may be used to inject a heat dissipation medium into the protective shell 200 . The heat generated by the memory chip 300 may be transmitted through the heat dissipation medium and dissipated more quickly to the protective shell 200 .

[0067] In addition, see Figure 7As shown, the reinforcing ribs 120 can also be arranged in a fourth manner based on the third arrangement. Three reinforcing ribs 120 with smaller curvatures and two reinforcing ribs 120 with larger curvatures are formed, the three reinforcing ribs 120 with smaller curvatures are arranged in parallel, and the two reinforcing ribs 120 with larger curvatures are arranged in parallel. The reinforcing ribs 120 with smaller curvatures extend in a direction orthogonal to the reinforcing ribs 120 with larger curvatures.

[0068] See also Figure 8 As shown, two reinforcing ribs 120 with a smaller curvature are provided, and two reinforcing ribs 120 with a larger curvature are also provided. Similarly, the extending directions of the reinforcing ribs 120 with a smaller curvature and the reinforcing ribs 120 with a larger curvature can be orthogonal.

[0069] Also, see Fig. 9 As shown, the reinforcing rib 120 may include a plurality of raised protrusions, which are arranged in sequence. The shape of the protrusions may be circular or square. The protrusions may be interconnected or disconnected.

[0070] Furthermore, see Fig.10 As shown, the reinforcing ribs 120 can also be arranged obliquely on the plate body 110, for example, multiple reinforcing ribs 120 can be parallel to each other. The extending directions of the reinforcing ribs 120 in the upper and lower cover plates 100 can be the same or different. For example, when the reinforcing ribs 120 are extended obliquely, the extending directions of the reinforcing ribs 120 in the upper and lower cover plates are crossed, or even orthogonal.

[0071] In one embodiment of the present application, two plate bodies 110 are provided, and the two plate bodies 110 are arranged in a stacked manner, and the reinforcing ribs 120 on one plate body 110 are aligned and matched with the reinforcing ribs 120 on the other plate body 110 .

[0072] In this embodiment, the plate body 110 of the cover plate 100 is provided with two plate bodies 110, which are stacked together. The reinforcing ribs 120 on one plate body 110 are aligned and matched with the reinforcing ribs 120 on the other plate body 110, forming a double-layer structure. This design can provide stronger protection and support while maintaining the unity of the overall structure.

[0073] In one embodiment of the present application, a plurality of plate bodies 110 are provided, and the plurality of plate bodies 110 are provided in the same layer, and adjacent plate bodies 110 are spliced ​​together. The plurality of plate bodies 110 can be spliced ​​together by welding. For example, the plate body 110 is one quarter of the surface of the protective shell 200, and the plate body 110 can be provided with four pieces, and the plurality of plate bodies 110 are spliced ​​together and covered on the surface of the protective shell 200.

[0074] Through the description of the above specific embodiments, the specific implementation methods of the present application in terms of structural design, layout of the reinforcing ribs 120, combination of the plate body 110, etc. are demonstrated, demonstrating the innovation and practicality of the present invention.

[0075] See also Figures 11 to 16 As shown, the present application also provides a data protection device, which includes a protective shell 200 and a cover plate 100, wherein two cover plates 100 are provided, and the two cover plates 100 are respectively provided on the opposite outer surfaces of the protective shell 200. The cover plates 100 can be respectively provided on the upper surface and the lower surface of the protective shell 200. By providing the cover plates 100 on the opposite outer surfaces of the protective shell 200, this upper and lower double-layer protection structure provides better protection for the storage chip 300, ensuring the security and stability of the data.

[0076] The protective shell 200 includes: an upper cover 220 and a lower cover 230 that are opposite to each other. The upper cover 220 and the lower cover 230 are made of metal, and the metal has good mechanical strength. The upper cover 220 and the lower cover 230 are arranged to form a storage space 201, and the storage space 201 is used to place the storage chip 300. At least one of the upper cover 220 and the lower cover 230 is provided with a wire port 202, and the wire port 202 is used to set a data line 600 connected to the storage chip 300. The data parameters of the vehicle are transmitted to the storage chip 300 through the data line 600, and the storage chip 300 can save the data parameters. When analysis is required, the data parameters are downloaded through the data line 600.

[0077] A reinforcing structure is provided on the surface of at least one of the upper cover 220 and the lower cover 230. The reinforcing structure can be provided on the upper cover 220 or on the lower cover 230. Alternatively, the reinforcing structure is provided on both the upper cover 220 and the lower cover 230. In this embodiment, the upper cover 220 and the lower cover 230 can withstand a certain impact force, and the storage space 201 formed by the upper cover 220 and the lower cover 230 can protect the storage chip 300 and reduce the impact on the storage chip 300. In addition, a reinforcing structure is also provided on the upper cover 220 and the lower cover 230. The structural strength of the upper cover 220 or the lower cover 230 can be improved by providing the reinforcing structure. When impacted, the structural stability can be maintained, deformation can be reduced, and more favorable protection can be provided for the storage chip 300. On this basis, a cover plate 100 is provided on the surface of the upper cover 220 away from the lower cover 230, and a cover plate 100 is also provided on the surface of the lower cover 230 away from the upper cover 220. By configuring the protective shell 200 in cooperation with the cover plate 100 , the memory chip 300 can be further protected, and the impact on the memory chip 300 can be reduced, so that the memory chip 300 can provide as complete data as possible.

[0078] The data protection device may further include a housing 400, and the protective shell 200 is disposed inside the housing 400. The housing 400 includes a first shell 410 and a second shell 420, and the first shell 410 and the second shell 420 are oppositely buckled and disposed outside the protective shell 200.

[0079] More specifically, the data protection device includes a protective sleeve 700, and the protective shell 200 and the protective sleeve 700 are both arranged in the outer shell 400. It can be understood that the protective sleeve 700, the protective shell 200 and the outer shell 400 are sequentially arranged from the position of the memory chip 300 to the outside, thereby forming a three-layer protective layer, further improving the protection of the memory chip 300. The protective sleeve 700 can be provided with a heat sink 800, and the heat sink 800 is used to improve the heat dissipation effect of the memory chip 300. The data protection device also includes a card sleeve 900, which can be set on the data line 600. The card sleeve 900 can be made of rubber, plastic, or resin material, etc., and the friction between the data line 600 and the outer shell 400 can be reduced by the setting of the card sleeve 900.
