[0002] On July 1, 2022, the national standard "Automobile Driving Recorder" (GB / T 19056-2021) was officially implemented. Appendix E of the standard puts forward clear requirements for the protection performance of on-board protective memory. Correspondingly, the on-board protective memory on the market requires higher performance disaster prevention and recovery. The core of the on-board protective memory is the storage module. In order to improve the disaster prevention and recovery performance, in addition to improving the external protection of the storage module on the one hand, how to improve the storage module itself is also an extremely important research direction.

[0003] Most storage boxes on the market currently use a gold finger reading method, which is to set one or more gold finger segments on the storage module to read data. However, these gold finger segments are easily damaged under conditions such as fire and high temperature, which makes the data stored in the storage box unreadable, causing inconvenience for subsequent accident analysis and restoration. Summary of the invention

[0010] Furthermore, the external circuit board of the storage module is a second circuit board extending outside the phase change protective shell, and an integral or split welding structure is adopted between the second circuit board and the storage medium of the storage module, which is used for data reading and writing transmission between the storage medium of the storage module and the external terminal.

[0011] Preferably, the second circuit board is a flexible circuit board.

[0012] Furthermore, a group of gold fingers serving as a reading interface is arranged on the second circuit board.

[0013] As one solution, there are at least two gold fingers, one located at the outer end of the second circuit board, and the other located in the middle of the second circuit board as a spare interface.

[0014] As another solution, there are at least three gold fingers, one located at the outer end of the second circuit board, another located in the middle of the second circuit board as a backup interface, and the third is arranged at the part of the second circuit board located in the phase change protective shell.

[0015] Furthermore, the phase change protective shell is a pair of phase change shells, the two phase change shells are mutually engaged and wrap the storage medium of the storage module; the interior of the phase change shell is filled with phase change material.

[0029] The present invention can be better understood according to the following embodiments.

At the same time, the terms such as "upper", "lower", "front", "back", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content. Example 1

[0031] Combination Figures 1 to 3As shown, the utility model provides a storage box with multiple reading methods, including a storage module 1 and a phase-change protective shell 2; the storage medium of the storage module 1 is protected by being wrapped by the phase-change protective shell 2, and the flexible circuit of the storage module 1 extending out of the phase-change protective shell 2 can realize data transmission with an external terminal; the storage module 1 can realize data transmission with an external terminal through an external circuit board extending out of the phase-change protective shell 2; a reading interface for data reading is provided at the storage medium of the storage module 1 and on the external circuit board. By embedding the storage module 1 in the phase-change protective shell 2 and providing multiple data reading interfaces on the storage module 1, when subjected to a high temperature disaster, the entire storage box has ways to read data at different stages, which greatly improves the data integrity and availability of the storage box in a disaster recovery environment.

[0032] Combination Figure 2 As shown, in this embodiment, the storage module 1 includes a first circuit board 11 and a storage chip 112 mounted on the first circuit board 11 as a storage medium.

[0033] In this embodiment, the first circuit board 11 is a rigid circuit board, and a group of data reading points 111 are reserved on the upper portion thereof for connecting the storage chip 112 with an external terminal and realizing data transmission.

[0034] In this embodiment, the external circuit board of the storage module 1 is a second circuit board 12 extending outside the phase change protective shell 2. An integral or split welding structure is adopted between the second circuit board 12 and the storage medium of the storage module 1, which is used for data reading, writing and transmission between the storage medium of the storage module 1 and the external terminal.

[0035] In this embodiment, the second circuit board 12 is a flexible circuit board, on which a group of gold fingers 121 serving as a reading interface are disposed for reading relevant driving data.

[0036] In this embodiment, there are three gold fingers 121, one is located at the outer end of the second circuit board 12, another is located in the middle of the second circuit board 12 as a spare interface, and the third is arranged at the part of the second circuit board 12 located in the phase change protective shell 2.

[0037] When a general accident occurs, there is no need to open the phase-change protective shell 2, and the undamaged gold finger 121 can be selected according to the degree of damage to directly read the relevant data. When a major accident occurs, the first circuit board 11 has a stronger disaster resistance than the second circuit board 12. By setting a data reading point 111 on the first circuit board 11, the purpose of reading data by opening the phase-change protective shell 2 and connecting the data reading point 111 can be achieved in the event of a serious accident, even if the second circuit board 12 exposed outside the protective box is completely damaged.

[0038] Combination Figure 5 and Figure 6 As shown, in this embodiment, the phase change protective shell 2 is a pair of phase change shells 21, and the two phase change shells 21 are mutually engaged and wrap the storage medium of the storage module 1; the interior of the phase change shell 21 is filled with phase change material. The phase change shells 21 are made of stainless steel, mutually engaged and form a cavity between the inner sides, and the cavity is used to accommodate the storage module 1. When the storage box is subjected to high temperature, the heat will be conducted to the phase change material through the phase change shell 21, and the phase change material will undergo a phase change to absorb heat, protecting the storage module 1 from damage due to high temperature.

[0039] In this embodiment, a groove 212 for placing the storage medium of the storage module 1 and a wire slot 22 for leading out an external circuit board are reserved inside the phase change housing 21 .

[0040] In this embodiment, a circle of rubber grooves 212 for filling with thermally conductive silicone is arranged around the outer periphery of the groove 212 on the inner side of the phase change housing 21. When the storage box is subjected to high temperature, the thermally conductive silicone can improve the heat transfer efficiency between the housings and prevent the internal storage module 1 from being damaged due to excessively high local temperature between the housings.

[0041] In this embodiment, the outer surface of the phase change housing 21 is provided with reinforcing ribs 211. The design of the reinforcing ribs 211 can provide a certain degree of pressure resistance when the storage box is subjected to external extrusion and impact, thereby protecting the internal storage module 1 from damage.

[0042] At present, the vehicle-mounted protective storage still has different types of protection technologies outside the storage box. The flexible second circuit board 12 is very easy to be damaged in the event of an accident because of its soft performance and the fact that it is generally extended outside the protective device for easy reading. Although there are multiple gold finger interfaces, if it is a serious accident, there will inevitably be a situation where no gold finger is available. In this case, it is extremely difficult to read data. The storage box of the utility model also sets a data reading point 111 on the rigid first circuit board 11, and the rigid first circuit board 11 is located at the innermost position of the storage box, which greatly ensures safety. Therefore, when a serious accident occurs, even if there is no gold finger to read, data can be read through the data reading point 111 on the first circuit board 11, thereby restoring the truth of the accident. Example 2

[0043] The difference between this embodiment and the first embodiment is that two gold fingers 121 are provided on the flexible second circuit board 12 as reading interfaces for reading relevant driving data. One of the gold fingers 121 is located at the outer end of the second circuit board 12, and the other is located on the part of the second circuit board 12 located in the phase change protective shell 2, and the phase change protective shell 2 is used to protect the gold fingers 121.

[0044] The utility model provides a storage box with multiple reading modes and a method. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the utility model. All components not specified in this embodiment can be implemented by existing technologies.
