Description

Technical Field

[0001] This utility model relates to the field of vehicle networking equipment, and in particular to an Internet of Things vehicle controller with an anti-tamper mechanism. Background Technology

[0002] With the rapid development of vehicle networking technology, IoT vehicle controllers have become core equipment in fields such as intelligent transportation, logistics management, and vehicle safety monitoring. In applications such as intelligent control systems for bulk logistics and active safety defense systems for hazardous chemical transport vehicles, vehicle controllers are responsible for collecting and transmitting key data such as vehicle trajectory, cargo status, and driving behavior in real time, which is the foundation for realizing intelligent vehicle management and safe operation.

[0003] Currently, most vehicle controllers on the market are installed using ordinary bolt fastening, lacking anti-tamper structures and facing risks such as illegal disassembly and malicious damage. Malicious attackers may disassemble the controller to perform reverse engineering, steal data, or implant malicious hardware, thus posing a serious threat to the entire vehicle networking system. For example, in logistics transportation, to cover up "cross-border" cargo operations, drivers or related personnel may attempt to disassemble the controller to interrupt data upload; in high-risk scenarios such as hazardous chemical transportation, if the controller is removed, it can easily cause the active safety protection system to fail, increasing the risk of accidents; in addition, in applications such as official vehicle management, anti-tamper mechanisms are also an important guarantee to prevent equipment loss, misuse, or data tampering. Utility Model Content

[0004] This utility model provides an IoT vehicle controller with an anti-tamper mechanism, which can solve the problem that existing IoT vehicle controllers with anti-tamper mechanisms lack anti-tamper structures and are subject to risks such as illegal disassembly and malicious damage.

[0005] An IoT vehicle controller with an anti-tamper mechanism includes a mounting sheet metal and a vehicle controller mounted on the mounting sheet metal. The top of the vehicle controller is covered with a cover, and a plurality of first threaded sleeves are fixedly provided on the inner bottom wall of the vehicle controller. A plurality of screws threadedly connected to the first threaded sleeves are inserted inside the cover, and a connector is fixedly provided on the top of each screw. Each connector has a hollow groove inside and a fixed plate is fixedly installed. Each connector is rotatably connected to a rotating head. Each rotating head has multiple push blocks fixedly installed at its bottom. Each fixed plate and the rotating head have a rotating plate. Each rotating plate has multiple stops fixedly installed at its top. Each stop is located between two adjacent push blocks, and each stop has an inclined surface structure on one side. Each rotating plate and the fixed plate have multiple elastic connecting components for realizing the up and down movement of the rotating plate.

[0006] Preferably, the elastic connection assembly includes a guide rod slidably connected to the fixed plate and a spring sleeved on the guide rod, with the top end of the guide rod fixedly connected to the rotating plate.

[0007] Preferably, each connector has a through hole located between the rotating plate and the fixed plate, and a limiting rod can be inserted into the through hole.

[0008] Preferably, a base pad is fixed on the mounting sheet metal, the base pad is made of rubber, and the vehicle controller is mounted on the base pad.

[0009] Preferably, a plurality of second threaded sleeves are fixed inside the base pad, and a connecting plate is fixed on the vehicle controller and above the second threaded sleeves. Screws are inserted inside the connecting plate and are threadedly connected to the second threaded sleeves.

[0010] Preferably, both the connector and the screw head are spherical.

[0011] Preferably, the connector head has a cross-shaped groove, and the screw has a plum blossom-shaped groove.

[0012] Preferably, the bottom pad has a through groove in the middle, and the through groove is filled with potting compound.

[0013] Preferably, a conduit is fixed inside the base pad, and the conduit is connected to the through groove.

[0014] Preferably, the housing and cover of the vehicle controller are both made of high-strength metal.

[0015] This utility model provides an IoT vehicle controller with an anti-tamper mechanism, which has the following advantages: 1. The cover, through the rotation of the connector, causes the screw to screw into the first threaded sleeve, securing the cover to the vehicle controller body and completing the installation and locking. When the rotating head is rotated in the reverse direction, the push block rotates and contacts the inclined structure of the stop block. Due to the guiding effect of the inclined surface, the rotational force is converted into downward pressure on the rotating plate. The rotating plate moves downward under pressure, and the stop block also descends synchronously, preventing the push block from effectively pushing against the stop block. Therefore, the rotational force applied to the rotating head cannot be effectively transmitted to the connector and screw through the stop block and rotating plate, preventing the screw from being loosened and achieving the purpose of preventing tampering.

[0016] 2. When professional maintenance personnel disassemble the connector, a limiting rod is inserted between the rotating plate and the fixed plate through the through hole to support the rotating plate and prevent it from moving downwards. This allows the rotating head to be rotated and disassembled in the reverse direction. This unlocking method relies on the cooperation of the through hole and the limiting rod to unlock the self-locking structure. The through hole is relatively simple and concealed; ordinary users cannot easily obtain or discover this unlocking method simply by observing its location. This provides an anti-tampering effect while facilitating disassembly and maintenance by authorized personnel. Attached Figure Description

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figures 1 to 8As shown in the figure, this utility model provides an IoT vehicle controller with an anti-tamper mechanism, including a mounting sheet metal 1 and a vehicle controller 2 mounted on the mounting sheet metal 1. A cover 3 is fitted over the top of the vehicle controller 2. Multiple first threaded sleeves 4 are fixedly mounted on the inner bottom wall of the vehicle controller 2. Multiple screws 6, threadedly connected to the first threaded sleeves 4, are inserted inside the cover 3. Each screw 6 has a connector 5 fixedly mounted on its top. Each connector 5 has a hollow groove and a fixing plate 7 fixedly mounted inside. Each connector 5 is rotatably connected to a rotating head 8. Multiple push blocks 11 are fixedly provided at the bottom of the rotating head 8. A rotating plate 13 is provided between the fixed plate 7 and the rotating head 8. Multiple stops 12 are fixedly provided at the top of the rotating plate 13. Each stop 12 is located between two adjacent push blocks 11, and each stop 12 has a sloping structure on one side. Multiple elastic connecting components for realizing the up and down movement of the rotating plate 13 are provided between the rotating plate 13 and the fixed plate 7. The elastic connecting components include a guide rod 9 slidably connected to the fixed plate 7 and a spring 10 sleeved on the guide rod 9. The top end of the guide rod 9 is fixedly connected to the rotating plate 13.

[0021] The cover 3 is placed on top of the vehicle controller 2. Using a tool, the rotating head 8 is rotated, causing the push block 11 at its bottom to contact the vertical horizontal surface of the stop block 12. As the push block 11 rotates, it pushes the stop block 12 on the rotating plate 13 to move, thereby causing the fixing plate 7 and the connector 5 to rotate under the action of the guide rod 9. Each screw 6 is screwed into the first threaded sleeve 4 from top to bottom, completing the locking. When the rotating head 8 is rotated in the opposite direction for disassembly, the rotating head 8 rotates, causing the push block 11 to rotate. The push block 11 contacts the inclined structure of the stop block 12. Using the guiding effect of the inclined surface, the rotating plate 13 is pressed down, compressing the spring 10. When the rotating plate 13 moves downward, the stop block 12 on it moves downward simultaneously, making it difficult to achieve the pushing force between the push block 11 and the stop block 12. Therefore, the rotating head 8 cannot achieve the reverse rotation of the connector 5 and the screw 6, thus achieving an anti-tampering effect.

[0022] In some specific implementation plans, such as Figure 4 and Figure 5 As shown, each connector 5 has a through hole 14 located between the rotating plate 13 and the fixed plate 7. A limiting rod can be inserted into the through hole 14. When professional maintenance personnel disassemble the connector 5, the limiting rod is inserted between the rotating plate 13 and the fixed plate 7 through the through hole 14 to support the rotating plate 13 and prevent it from moving downwards. Thus, the rotating head 8 can be used to achieve reverse disassembly and rotation of the rotating plate 13.

[0023] A through hole 14 is provided on the connector 5 to facilitate disassembly by rotating the connector 5 in the reverse direction. This unlocking method is based on the cooperation between the through hole 14 and the limit rod to unlock the self-locking structure. The through hole 14 is relatively simple and hidden. Ordinary users cannot obtain or easily know this unlocking method from the setting of the through hole 14 alone. It plays an anti-disassembly role while facilitating disassembly and maintenance by authorized personnel.

[0024] In some specific implementation plans, such as Figure 1 , Figure 2 and Figure 7 As shown, a base pad 15, made of rubber, is fixed on the mounting sheet metal 1. The vehicle controller 2 is mounted on the base pad 15, which acts as a buffer to protect the vehicle controller 2. Multiple second threaded sleeves 18 are fixed inside the base pad 15. A connecting plate 17 is fixed on the vehicle controller 2 and above the second threaded sleeves 18. Screws 16 are inserted inside the connecting plate 17 and are threadedly connected to the second threaded sleeves 18 to fix the vehicle controller 2 to the base pad 15.

[0025] In some specific implementation plans, such as Figure 4 , Figure 6 and Figure 7 As shown, both the connector 5 and screw 16 have spherical heads to prevent them from being loosened using external tools. The connector 5 has a Phillips head groove for use with a Phillips screwdriver. The screw 16 has a Torx-shaped groove and uses an internal Torx hole, which is less common than an internal hex socket, allowing authorized personnel to disassemble it with specialized tools, thus improving its tamper resistance.

[0026] In some specific implementation plans, such as Figure 1 and Figure 3 As shown, a through groove 19 is provided in the middle of the bottom pad 15. The inside of the through groove 19 is filled with potting compound 21. A conduit 20 is fixed inside the bottom pad 15 and is connected to the through groove 19.

[0027] To further enhance anti-tamper protection, potting compound 21 can be injected into the through groove 19 through the conduit 20 inside the base pad 15. After curing, the connection strength between the vehicle controller 2 and the mounting sheet metal 1 is increased, thus enhancing anti-tamper performance. If the vehicle controller 2 is removed from the mounting sheet metal 1, the potting compound 21 must be damaged. The disassembly marks cannot be restored and can serve as evidence of disassembly.

[0028] The vehicle controller 2 housing and cover 3 are both made of high-strength metal materials, such as 304 stainless steel and aluminum alloy, which have good structural strength and prevent violent disassembly.

[0029] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: The cover 3 is placed on top of the vehicle controller 2. A Phillips screwdriver is inserted into the Phillips head groove of the connector 5, and torque is applied and transmitted through the connector 5 to the screw 6, causing it to screw into the first threaded sleeve 4, thereby securing the cover 3 to the main body of the vehicle controller 2 and completing the installation and locking. When the rotating head 8 is rotated in the reverse direction, the push block 11 rotates and contacts the inclined structure of the stop block 12. Due to the guiding effect of the inclined surface, the rotational force is converted into downward pressure on the rotating plate 13. The rotating plate 13 moves downward under pressure, and the stop block 12 also descends synchronously, preventing the push block 11 from effectively pushing against the stop block 12. Therefore, the rotational force applied to the rotating head 8 cannot be effectively transmitted to the connector 5 and the screw 6 through the stop block 12 and the rotating plate 13, causing the screw 6 to be unable to be loosened, thus achieving the purpose of preventing tampering.

[0030] For authorized professional maintenance personnel, during disassembly, a limiting rod is inserted through the through hole 14 on the side wall of connector 5. The limiting rod supports the rotating plate 13, preventing it from shifting downwards when the rotating head 8 reverses. When the push block 11 rotates and contacts the inclined surface of the stop block 12, it can push the rotating plate 13 to rotate, restoring torque transmission, thereby allowing the screw 6 to be unscrewed normally, completing the disassembly.

[0031] When installing the vehicle controller 2 onto the vehicle mounting sheet metal 1, the vehicle controller 2 is placed on the base pad 15 and initially secured by the connecting plate 17 and screws 16. The screws 16 feature an unusual pentagonal groove design, increasing the difficulty of disassembly using non-specialized tools.

[0032] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
