[0049] 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.

[0050] See also Figures 1 to 4 ,as well as Figures 11 to 13 As shown, the present application provides a protective shell 100, and the protective shell 100 in the present application can be used on cars, airplanes, and ships. Traffic accidents may occur when cars are driving, flight accidents may occur when airplanes are flying, and 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 protective shell 100 can be set on such vehicles, and the protective shell 100 can provide protection for the storage chip 200 to prevent the loss of data stored in the storage chip 200.

[0051] The protective shell 100 includes: an upper cover 110 and a lower cover 120 facing each other, and the upper cover 110 and the lower cover 120 are made of metal, and the metal has good mechanical strength. The upper cover 110 and the lower cover 120 are arranged to form a storage space 101, and the storage space 101 is used to place the storage chip 200. At least one of the upper cover 110 and the lower cover 120 is provided with a wire port 102, and the wire port 102 is used to set a data line 300 connected to the storage chip 200. The data parameters of the vehicle are transmitted to the storage chip 200 through the data line 300, and the storage chip 200 can save the data parameters. When analysis is required, the data parameters are downloaded through the data line 300.

[0052] A reinforcing rib 103 is disposed on the surface of at least one of the upper cover 110 and the lower cover 120. The reinforcing rib 103 may be disposed on the upper cover 110 or the lower cover 120. Alternatively, the reinforcing rib 103 may be disposed on both the upper cover 110 and the lower cover 120. The reinforcing rib 103 may be integrally formed with the upper cover 110 or the lower cover 120.

[0053] In this embodiment, the upper cover 110 and the lower cover 120 can withstand a certain impact force, and the storage space 101 formed by the upper cover 110 and the lower cover 120 can protect the storage chip 200 and reduce the impact on the storage chip 200. In addition, reinforcing ribs 103 are also provided on the upper cover 110 and the lower cover 120. The provision of the reinforcing ribs 103 can improve the structural strength of the upper cover 110 or the lower cover 120, and when impacted, the structural stability can be better maintained, deformation can be reduced, and more favorable protection can be provided for the storage chip 200. Therefore, by providing the protective shell 100, the storage chip 200 can be protected, the impact on the storage chip 200 can be reduced, and the storage chip 200 can provide as complete data as possible, which is convenient for completing the analysis of the cause of the accident.

[0054] It should be noted that in the present application, the memory chip 200 will generate a large amount of heat when storing or outputting data. If this heat accumulates around the memory chip 200, it will reduce the working efficiency of the memory chip 200 or even burn the memory chip 200. The reinforcing ribs 103 are arranged on the upper cover 110, and the reinforcing ribs 103 protrude from the surface of the upper cover 110, which is equivalent to increasing the contact area between the upper cover 110 and the surrounding air. Similarly, the reinforcing ribs 103 can also be arranged on the lower cover 120, which also increases the contact area between the lower cover 120 and the surrounding space. The heat generated by the memory chip 200 can be dissipated through the upper cover 110 and the lower cover 120.

[0055] In summary, the protective shell 100 in the present application not only protects the memory chip 200 and reduces the impact on the memory chip 200 , but also can dissipate heat to reduce the heat generated by the memory chip 200 .

[0056] The upper cover 110 and the lower cover 120 can be connected together by snapping, or fixed together by welding, or fixed by glue layer or thread connection. The wire opening 102 can be set only on the upper cover 110, or on the lower cover 120. A notch can also be set at the relative position of the upper cover 110 and the lower cover 120, and when the upper cover 110 and the lower cover 120 are opposite, the two notches are relatively snapped together to form the wire opening 102.

[0057] In one embodiment of the present application, the upper cover 110 and the lower cover 120 are buckled together; there are two specific buckling methods. The first buckling method is that the lower cover 120 is buckled with the upper cover 110, that is, the edge of the lower cover 120 is buckled with the edge of the upper cover 110. The second buckling method is that the upper cover 110 is buckled with the lower cover 120, and the edge of the upper cover 110 is buckled with the edge of the lower cover 120. The buckling method can also be further combined with the welding method, and welding is performed along the buckled edges, which can improve welding efficiency.

[0058] In one embodiment of the present application, the upper cover 110 has a first surface 111 facing the lower cover 120, and the lower cover 120 has a second surface 121 facing the upper cover 110. The first surface 111 and the second surface 121 are both provided with reinforcing ribs 103. The first surface 111 and the second surface 121 are arranged opposite to each other. The areas of the first surface 111 and the second surface 121 are relatively large, and the provision of reinforcing ribs 103 at this position can further improve the structural strength of the protective shell 100.

[0059] In addition, reinforcing ribs 103 may also be provided on the sides of the upper cover 110 and the lower cover 120 to further improve the overall structural strength of the protective shell 100 .

[0060] In one embodiment of the present application, a first groove 104 is formed between the reinforcing ribs 103 disposed on the first surface 111, and a second groove 105 is formed between the reinforcing ribs 103 disposed on the second surface 121; it can be understood that there are multiple reinforcing ribs 103 disposed on the first surface 111, and the reinforcing ribs 103 protrude from the first surface 111, thereby forming a first groove 104 between adjacent reinforcing ribs 103. Similarly, there are multiple reinforcing ribs 103 disposed on the second surface 121, and a second groove 105 is formed between adjacent reinforcing ribs 103.

[0061] See also Figures 3 to 9 As shown, in the present application, there are various configurations for the first groove 104 and the second groove 105 .

[0062] The first arrangement is that there are multiple first grooves 104, and the multiple first grooves 104 can be arranged in parallel or crosswise. The spacing between at least two adjacent first grooves 104 is equal, for example, the spacing between each first groove 104 and other adjacent first grooves 104 is equal. Alternatively, the spacing between any two adjacent first grooves 104 is unequal; the arrangement density of the first grooves 104 varies, and the arrangement density of the first grooves 104 can be from dense to sparse from the edge position to the middle position of the first surface 111, or from sparse to dense.

[0063] Similarly, the second grooves 105 are provided with a plurality of them, and the spacing between at least some of the adjacent two second grooves 105 is equal, or the spacing between any two adjacent second grooves 105 is not equal. The arrangement of the second grooves 105 can refer to the arrangement of the first grooves 104. For example, the spacing between each second groove 105 and other adjacent second grooves 105 is equal. For another example, the arrangement density of the second grooves 105 varies, and the arrangement density of the second grooves 105 can be from dense to sparse from the edge position to the middle position of the second surface 121, or from sparse to dense.

[0064] The second setting is that at least some of the first grooves 104 have the same width, or the widths of any two first grooves 104 are different; for example, the widths of two first grooves 104 may be equal, or the widths of all first grooves 104 may be equal. Alternatively, the width of the first groove 104 may gradually change, for example, the width of the first groove 104 may gradually increase from the edge position to the middle position of the first surface 111, or the width of the first groove 104 may gradually decrease from the edge position to the middle position of the first surface 111.

[0065] The groove widths of at least some of the second grooves 105 are equal, or the groove widths of any two second grooves 105 are not equal. For example, the groove widths of two second grooves 105 may be equal, or the groove widths of all second grooves 105 may be equal. Alternatively, the groove widths of the second grooves 105 may gradually change, for example, the groove widths of the second grooves 105 may gradually increase from the edge position to the middle position of the second surface 121, or the groove widths of the second grooves 105 may gradually decrease from the edge position to the middle position of the second surface 121.

[0066] The third configuration is that at least some of the first grooves 104 have the same length, or any two of the first grooves 104 have different lengths; for example, two of the first grooves 104 have the same length, or all of the first grooves 104 have the same length. Alternatively, the lengths of each first groove 104 are different, or the lengths of the first grooves 104 gradually decrease from the edge of the first surface 111 to the middle, or the lengths of the first grooves 104 gradually increase.

[0067] At least some of the second grooves 105 have the same length, or the lengths of any two second grooves 105 are not equal. Similarly, for example, two second grooves 105 have the same length, or the lengths of all second grooves 105 are equal. Alternatively, the lengths of each second groove 105 are not equal, and for another example, the lengths of the second grooves 105 gradually decrease from the edge position to the middle position of the second surface 121, or the lengths of the second grooves 105 gradually increase.

[0068] The fourth configuration is that the groove depths of at least some of the first grooves 104 are equal, or the groove depths of any two first grooves 104 are not equal; in this regard, the groove depths of two first grooves 104 may be equal, or the groove depths of all first grooves 104 may be equal. In addition, the groove depths of each first groove 104 may be different, for example, multiple first grooves 104 are arranged in sequence, and the groove depths of the first grooves 104 gradually increase from the edge position to the middle position of the first surface 111, or the groove depths of the first grooves 104 gradually decrease, or the groove depths of the first grooves 104 gradually increase.

[0069] The groove depths of at least some of the second grooves 105 are equal, or the groove depths of any two second grooves 105 are not equal. For the second grooves 105, the groove depths of two second grooves 105 may be equal, or the groove depths of all second grooves 105 may be equal. In addition, the groove depths of each second groove 105 may be different, for example, multiple second grooves 105 are arranged in sequence, and the groove depths of the second grooves 105 gradually increase from the edge position to the middle position of the second surface 121. Alternatively, the groove depths of the second grooves 105 gradually decrease, or the groove depths of the second grooves 105 gradually increase.

[0070] In the present application, the specific settings of the first groove 104 and the second groove 105 of the protective shell 100 can be any one of the above-mentioned first setting, second setting, third setting and fourth setting, or any combination of the four settings.

[0072] In addition, the first vent 1101 is disposed at the corner of the first surface 111, and the second vent 1201 is disposed on a side of the second surface 121 away from the first vent 1101. For example, the protective case 100 is a cubic structure, and the first vent 1101 and the second vent 1201 are disposed near the diagonal position.

[0073] It should be noted that some heat absorbing materials can also be filled in the storage space 101. These heat absorbing materials can absorb the heat generated by the storage chip 200. The provision of the first ventilation hole 1101 and the second ventilation hole 1201 facilitates the subsequent filling of the heat absorbing materials into the storage space 101.

[0074] See also Fig.10 As shown, in one embodiment of the present application, the protective case 100 further includes a sawtooth piece 130, which is arranged along the first vent hole 1101 and the second vent hole 1201, and extends toward the storage space 101.

[0075] In addition, in order to improve the sealing effect of the protective shell 100 , a sealing membrane may be provided on the first vent hole 1101 and the second vent hole 1201 to prevent external water vapor from entering the storage space 101 .

[0076] Furthermore, two sealing diaphragms are provided, and the two sealing diaphragms are respectively covered on the first vent hole 1101 and the second vent hole 1201; wherein the sealing diaphragm is one of polyimide, polyethylene, PET, PVC, metal and bakelite.

[0077] In addition, the sealing film can be fixed on the protective shell 100 by pasting. It can be fixed on the protective shell 100 by means of tape. When the sealing film is made of PI, PE, PET, or PVC, the tape is provided with an adhesive layer, and the sealing film is fixed on the protective shell 100 by the adhesive layer.

[0078] When the sealing diaphragm is made of metal or bakelite, a one-component silicone sealant can be used to adhere the sealing diaphragm.

[0079] In one embodiment of the present application, the first surface 111 is formed with a first recessed area 112, the first vent 1101 is disposed in the first recessed area 112, the second surface 121 is provided with a second recessed area 122, the second vent 1201 is disposed in the second recessed area 122, the first recessed area 112 is communicated with the adjacent first groove 104, and the second recessed area 122 is communicated with the adjacent second groove 105.

Similarly, the second grooves 105 are connected in the same second partition 123, so that the airflow in the second partition 123 can be improved.

[0081] See also Fig.14 and Fig.15As shown, the present application also provides a data protection device, which includes a housing 400 and a protective shell 100 as described above, and the protective shell 100 is arranged in the housing 400. For example, the protective shell 100 and the protective cover 600 are both arranged in the housing 400. It can be understood that from the position of the memory chip 200 to the outside, the protective cover 600, the protective shell 100 and the housing 400 are sequentially arranged, thereby forming a three-layer protective layer, further improving the protection of the memory chip 200. The protective cover 600 can be provided with a heat sink 700, and the heat sink 700 improves the heat dissipation effect of the memory chip 200. The data protection device also includes a card sleeve 500, which can be set on the data line 300.

In addition, reinforcing ribs 103 are also provided on the upper cover 110 and the lower cover 120. The provision of the reinforcing ribs 103 can improve the structural strength of the upper cover 110 or the lower cover 120, and when impacted, the structural stability can be better maintained, deformation can be reduced, and more favorable protection can be provided for the storage chip 200. Therefore, by providing the protective shell 100, the storage chip 200 can be protected, the impact on the storage chip 200 can be reduced, and the storage chip 200 can provide as complete data as possible, which is convenient for completing the analysis of the cause of the accident.

[0083] In addition, the memory chip 200 generates a lot of heat when storing or outputting data. If this heat accumulates around the memory chip 200, it will reduce the working efficiency of the memory chip 200 or even burn the memory chip 200. The reinforcing ribs 103 are arranged on the upper cover 110, and the reinforcing ribs 103 protrude from the surface of the upper cover 110, which is equivalent to increasing the contact area between the upper cover 110 and the surrounding air. Similarly, the reinforcing ribs 103 can also be arranged on the lower cover 120, which also increases the contact area between the lower cover 120 and the surrounding space. The heat generated by the memory chip 200 can be dissipated through the upper cover 110 and the lower cover 120.
