[0030] The utility model embodiment discloses a housing, see Figure 1 As shown, the shell includes a first cover plate 1, a shell body 2 and a second cover plate 3, each side of the first cover plate 1 is provided with at least one first protruding fin 11, and a first card groove 12 is formed between two adjacent first protruding fins 11; each side of the second cover plate 3 is provided with at least one second protruding fin 31, and a second card groove 32 is formed between two adjacent second protruding fins 31.

[0031] Among them, see Figure 1 As shown, the shell 2 is a frame structure surrounded by four side panels, and each side edge at one end of the frame structure is provided with a first groove 21 that cooperates with the first protruding fin 11 on the corresponding side edge on the first cover plate 1 and a third protruding fin 22 that cooperates with the first card slot 12, and each side edge at the other end of the frame structure is provided with a second groove 23 that cooperates with the second protruding fin 31 on the corresponding side edge on the second cover plate 3 and a fourth protruding fin 24 that cooperates with the second card slot 32.

[0032] See also Figure 1 As shown, each side of the first cover plate 1 and / or the second cover plate 3 is provided with at least one fixing portion 4 , and the housing 2 is provided with a matching portion 5 matching with each fixing portion 4 .

[0033] The shell of the utility model is composed of three parts: a first cover plate 1, a shell body 2 and a second cover plate 3. Among them, the first cover plate 1 can be used as an upper cover plate or a lower cover plate. Similarly, the second cover plate 3 can be used as an upper cover plate or a lower cover plate. The utility model does not limit them.

[0034] Furthermore, in a specific implementation, the fixing portion 4 can be provided on both the first cover plate 1 and the second cover plate 3, or only on one of them. The component without the fixing portion 4 can be fixed to the shell 2 by means of gluing, hot-melt welding, etc.

[0035] In the embodiment of the present utility model, see Figure 2 and Figure 3 As shown, the first cover plate 1 is used as the lower cover plate, the second cover plate 3 is used as the upper cover plate, a fixing portion 4 is provided on the second cover plate 3, and a matching portion 5 is provided on one end of the housing 2 that matches with the upper cover plate.

[0036] Further, see Figure 1 and Figure 3 As shown, the fixing portion 4 is a groove processed on the edge of the outer surface of the first cover plate 1 and / or the second cover plate 3, and the matching portion 5 is a small tooth piece that is bent and embedded in the groove.

[0037] Furthermore, in order to allow the first cover plate 1 or the second cover plate 3 to be completely placed in the groove after being bent after being covered on the shell 2, the depth of the groove is ≤ the thickness of the small tooth plate, and the length of the groove is ≥ the length of the small tooth plate.

[0038] Furthermore, in order to improve the strength of the shell, the first cover plate 1, the shell body 2 and the second cover plate 3 are all made of metal materials. In this embodiment, stainless steel is selected to make the shell.

[0039] Further, to facilitate the interaction between the protected components in the housing and the outside, see Figure 1 , Figure 2 and Figure 3 As shown, an outlet 25 is provided on a side plate of the housing 2 near the first cover plate 1 or the second cover plate 3 .

[0040] Furthermore, in an embodiment in which the drawings are not shown, in order to improve the stability of the protected part in the outer shell, a clamping portion is provided on the inner surface of the first cover plate 1 or the second cover plate 3. It should be noted that when the first cover plate 1 is an upper cover plate, the clamping portion is provided on the inner surface of the second cover plate 3. When the first cover plate 1 is a lower cover plate, a clamping portion is provided on the first cover plate 1. In another embodiment, the clamping portion can also be provided on the inner circumferential wall of the shell 2. Furthermore, in order to avoid contact between the protected part and the inner wall of the outer shell, a gap can be left between the protected part and the outer shell through the clamping portion. This arrangement can prevent heat from being quickly transferred to the protected part in a high temperature environment or the protected part from being hit under external force conditions.

[0041] The present utility model also provides a data recorder, see Figure 4 As shown, it includes an internal box 6, a protected component and the outer shell of the above embodiment, and the internal box 6 is arranged in the outer shell.

[0042] Among them, see Figure 5As shown, the protected component includes a storage module 7, a circuit board 8 and a transmission line 9. The storage module 7 is arranged on the circuit board 8. One end of the transmission line 9 is arranged on the circuit board 8, and the other end extends out of the housing and is connected to an external device.

[0043] Further, see Figure 4 As shown, the internal box 6 includes a box body 61 and an inner box 62 . A first cavity 65 is provided in the box body 61 . A first opening 612 communicating with the first cavity 65 is opened on the box body 61 .

[0044] The inner box 62 includes a box cover 621, the outer peripheral edge of the box cover 621 cooperates with the first opening 612, the box cover 621 is provided with a second opening 6211, the box cover 621 is provided with a protrusion 622 inserted into the first cavity 65, and the protrusion 622 is provided with a storage cavity 63 connected to the second opening 6211.

[0045] Furthermore, a hollow layer is formed between the inner wall of the box body 61 and the outer wall of the protrusion 622, and the hollow layer is filled with a phase-change liquid. The hollow layer is filled with a phase-change liquid. On the one hand, the phase-change liquid can improve the structural stability of the inner box when there is severe vibration. On the other hand, in a high-temperature environment, the phase-change liquid can absorb heat to provide thermal protection for the storage module 7 in the inner box. Even when the box body is damaged by heat, the outflow of the phase-change liquid can avoid the increase of pressure in the first cavity 65 caused by high temperature, which can cause mechanical damage or high-heat damage to the storage module 7. At the same time, under low-temperature conditions, the phase-change liquid can also prevent the loss of heat in the storage cavity 63, which may cause the storage module 7 to fail to work normally at low temperatures, thereby improving the stability of the operation of the protected device.

[0046] Furthermore, in order to improve the sealing performance of the inner box, after the box cover 621 is covered on the first opening 612, the contact surface between the box cover 621 and the first opening 612 is sealed and fixed with a sealant.

[0047] Furthermore, the storage cavity 63 is filled with sealant, and the sealant covers the storage module 7, the circuit board 8 and part of the transmission line 9 in the storage cavity 63. Furthermore, in order to further improve the stability of the storage module 7 in the storage cavity 63, prevent the storage module 7 from being separated from the storage cavity 63, and prevent moisture from entering the storage cavity 63 to improve its waterproof performance and avoid moisture from damaging the storage module 7 and the circuit board 8, after the protected component is placed in the storage cavity 63, it is filled with sealant so that the sealant covers the outside of the protected component in the storage cavity 63.

[0048] Furthermore, the box body 61 is a plastic box with a melting point less than 150°C. The box body 61 is made of plastic so that it can be melted in a high temperature environment, allowing the liquid or air in the hollow layer between the box body 61 and the inner box 62 to overflow, thereby avoiding high-temperature damage to the protected components in the inner box 62.

[0049] Furthermore, the inner box 62 is a plastic box or a metal box, and the melting point of the inner box 62 is greater than the melting point of the box body 61. By selecting the material of the inner box 62, the protected components in the inner box 62 can be further protected to prevent the box body 61 from melting under high temperature conditions, causing the inner box 62 to also melt and thus causing damage to the protected components.

[0050] Furthermore, the data logger also includes a thermal insulation pad, which is located between the internal box 6 and the inner wall of the outer shell.

[0051] The embodiments of the utility model achieve the following technical effects: the shell disclosed by the utility model is provided with corresponding fin protrusions and slots / grooves on the sides of each component, and a small tooth structure that can be quickly fixed is provided, thereby improving the protection performance of the data recorder shell, improving production efficiency, and reducing labor intensity to meet the needs of mass production.

[0052] Furthermore, the data logger containing the housing of the utility model can further protect the internal box and the protected components therein to ensure that they will not be mechanically damaged. At the same time, by designing the internal box into two parts, the box body and the internal box, and selectively filling the phase change liquid between the two, the high temperature and vibration protection of the protected components arranged in the internal box can be further improved to prevent them from being destroyed by high temperature in a high temperature environment or mechanically damaged by external forces.

[0053] Obviously, those skilled in the art should understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the embodiments of the present invention may be modified and varied in various ways.
