[0018] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0019] In this disclosure, unless otherwise indicated, directional terms such as "upper," "lower," "top," and "bottom" generally refer to the upper, lower, top, and bottom positions of the corresponding component in the direction of gravity when in use. "Inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself. Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0020] like Figure 1-4 As shown, the present disclosure provides a vehicle data recording device, including: a shell 1; a chip 3, arranged in the shell 1; a storage device 7, arranged in the shell 1 and communicatively connected to the chip 3; an interface 5, one end of which extends out of the shell 1, and the other end of which is communicatively connected to one or both of the chip 3 and the storage device 7; a high-temperature resistant layer, arranged on the outer wall of the shell 1 and having multiple layers; and a protective layer 6, arranged on the outside of the storage device 7 and having at least two layers.

[0021] Through the above technical solution, the shell 1 is used to protect the internal device. To ensure the strength of the shell 1, the shell 1 can be made of titanium alloy or stainless steel. The chip 3 is used to process data. For example, the chip 3 also has the functions of compressing data, analyzing data, and sending positioning. For example, the positioning module is installed to realize the positioning function. Even after the ordinary electronic positioning equipment burns out under high temperature, this device can still provide the final positioning function. The chip 3 is installed on the circuit board 2. The circuit board 2 has a large number of components such as capacitors and inductors, which constitute a backup power supply device. Once the external power is cut off, the circuit board 2 can delay the sending and receiving of receipts to ensure the integrity of the data. At the same time, it can also charge the storage device 7. After the power of the entire vehicle is cut off in a serious traffic accident such as a collision or fire, low-voltage electricity is provided to the entire vehicle, making it convenient for the driver and passengers to open the door and escape, avoiding being locked in the car and unable to escape. Of course, components such as capacitors can also be set in the storage device 7 to temporarily store electricity. The storage device 7 is used to store data for subsequent personnel to view. The interface 5 is connected to the vehicle system to achieve interaction with the entire vehicle. The interface 5 can be connected to the chip 3 and the storage system, or both. If connected to the chip 3, the data is stored in the storage device 7 after processing. If connected to the storage device 7, the data is first stored and then processed by the chip 3 to replace the previously stored data. If connected to both, the data is processed and stored at the same time, and then the processed data replaces the previously stored data. The shell 1 is provided with multiple high-temperature resistant layers on the outside, which can protect the storage device 7 in the shell 1 from damage after the vehicle catches fire. The protective layer 6 has at least two layers, which can protect the storage device 7 when the vehicle collides to prevent the storage device 7 from being damaged.

[0022] As an optional implementation, the temperature that the multiple layers of high-temperature resistant layers withstand increases layer by layer from the outside to the inside. In this way, even if the outer layer falls off under high temperature, the remaining inner layers can continue to play a protective role. The multiple layers of high-temperature resistant layers fall off layer by layer to increase the protection time, and the lower-priced high-temperature resistant materials are allowed to block the high temperature first. Even if the first line of defense is broken, the second line of high-temperature resistant materials will have a higher temperature resistance. The subsequent high-temperature resistant materials will even have a temperature resistance far greater than the maximum temperature of the actual combustion of the entire vehicle, fundamentally cutting off the high-temperature transmission path and preventing high temperature from entering the interior of the device. For example, the high-temperature resistant layer can be ceramic coating, alumina coating, silicate coating, phosphate coating, ceramic sheet, etc., which can be selected according to specific circumstances.

[0023] As an optional implementation, Figure 2 and Figure 4As shown, the protective layer 6 includes a reinforcing beam 61 and a buffer insulation layer 62. The reinforcing beam 61 is circumferentially arranged inside the shell 1 to form an installation space for placing the storage device 7, and the reinforcing beam 61 is spaced apart from the inner wall of the shell 1. The buffer insulation layer 62 is located in the installation space and is arranged on the outside of the storage device 7. The reinforcing beam 61 is circumferentially arranged on the outside of the storage device 7 to further protect the storage device 7 when the vehicle collides. The reinforcing beam 61 is spaced apart from the shell 1 so that even if the shell 1 is deformed, it will not affect the reinforcing beam 61. For example, the reinforcing beam There are multiple reinforcement beams 61 and they are spaced apart. On the one hand, this can prevent one of the reinforcement beams 61 from affecting the other reinforcement beams 61 after deformation. On the other hand, because the reinforcement beams 61 are made of metal, the spacing can prevent interference signals. Of course, the reinforcement beams 61 can also be hollowed out while ensuring strength. In order to ensure the strength of the reinforcement beams 61, the reinforcement beams 61 can be trapezoidal. The buffer insulation layer 62 plays a role of buffering and heat insulation. When a collision occurs, the buffer insulation layer 62 is first subjected to the impact force of the storage device 7, slowing down and buffering the storage device 7. For example, the buffer insulation layer 62 can be aerogel, foam or compressible plastic. The circuit board 2 is fixedly mounted on the reinforcement beam 61 by the mounting plate 9. The inner side of the cover 8 can be provided with a buffer insulation material to provide buffering and heat insulation between the cover and the circuit board 2.

[0024] Alternatively, as Figure 2-4 As shown, the installation space has an installation surface, and the buffer insulation layer 62 includes a bottom plate 621 arranged on the installation surface, an annular groove 623 arranged on the bottom plate 621, and a cover plate 622 provided on the side of the annular groove 623 away from the bottom plate 621. The outer wall of the annular groove 623 gradually tilts inward from the side close to the cover plate 622 to the side close to the bottom plate 621. The storage device 7 is integrally provided with a connecting plate 10, which is fixed to the bottom plate 621 by bolts. The strength of the connecting plate 10 is greater than that of the storage device. 7, the bolts are reinforced bolts to ensure the installation strength of the storage device 7, the hardness of the bottom plate 621 and the cover plate 622 is greater than the hardness of the annular groove 623, the annular groove 623 has a lower hardness and plays a role in buffering the horizontal impact force, the bottom plate 621 and the cover plate 622 have a higher hardness and play a role in fixing the core device and not being deformed by external impact; the annular groove 623 is set in an inverted trapezoidal shape, which decomposes the horizontal impact force into a partial downward force, so that the device is firmly fixed on the vehicle to prevent it from flying out or rolling.

[0025] As an optional embodiment, the storage device 7 is divided into multiple compartments, each compartment is provided with a separate storage unit, so as to avoid an error in one storage unit causing the entire data to be unable to be opened or analyzed, thereby reducing the risk.

[0026] As an optional implementation, at least two backup areas are provided in the storage device 7 to perform multiple backups of data. When one piece of data is damaged, the backup data can still be used to ensure data security.

[0027] As an optional implementation, Figure 3 As shown, an opening is provided on one side of the shell 1, and a cover 8 is provided at the opening. The cover 8 is welded to the shell 1, and the components are installed into the shell 1 through the opening. After the installation is completed, the cover 8 is welded to the shell 1 to prevent malicious opening, thereby improving data security.

[0028] As an optional implementation, Figure 3 As shown, the chip 3, storage device 7, and interface 5 are connected via multiple data cables 4 with the same function. This means that a single data cable 4 can perform data transmission. This multi-row arrangement ensures that even if some cables are damaged, the remaining cables can still communicate normally. The internal structure of the data cables 4 is made of large, high-temperature-resistant metal, and the external surface is wrapped with a material such as high-temperature-resistant mica tape to prevent the cables from breaking easily.

[0029] As an optional embodiment, the shell 1 is filled with an inert gas, such as argon. This gas does not burn and can isolate the high temperature of the outside world to form a gas isolation wall to protect the various parts of the device. The argon plays a second-level role in delaying and buffering shocks. Because the weight of the argon in the shell 1 is different from that of the device, when subjected to a large impact, the acceleration of the argon is much smaller than that of the storage device 7, which can serve the purpose of buffering the deceleration.

[0030] As an optional embodiment, the inner wall of the shell 1 is provided with a multi-layer anti-interference coating. In order to protect the device from interference from external signals, the inner surface of the shell 1 is coated with an electromagnetic shielding coating, a metal coating, and a conductive polymer coating. The multi-layer protective coating ensures that the interior of the device is not damaged by external influences.

[0031] Another object of the present disclosure is to provide a vehicle, comprising: the above-mentioned vehicle data recording device, which can record vehicle data for subsequent personnel to review, thereby determining the cause of the accident for subsequent improvements.
