Description

Technical Field

[0001] This application relates to the field of computer protection equipment technology, and in particular to a vehicle-mounted communication terminal and system. Background Technology

[0002] Protective cases for general-purpose computing devices are widely used in the transportation and storage of equipment in various special environments, especially in the military field, where they are crucial for ensuring the safe operation of electronic equipment. With the development of technology, military general-purpose computing devices are gradually becoming an important component of modern combat systems, and their supporting protective cases are receiving increasing attention. These products not only need to meet basic protection requirements, such as shock resistance, drop resistance, and dustproofing, but also need to be able to adapt to extreme environments, such as waterproofing, fireproofing, and information security.

[0003] The design of protective enclosures for general-purpose computing devices primarily employs the following common methods: first, adding thermal insulation materials to reduce the impact of external temperature changes on the equipment; second, utilizing sealed structures to minimize the possibility of dust entering the enclosure; and third, designing simple ventilation openings to promote airflow and aid heat dissipation. In addition, some products incorporate soft padding inside the enclosure to absorb impact, or add reinforcing components to critical areas to enhance overall strength. However, these methods often focus on achieving a single function and lack integrated solutions that comprehensively consider multiple needs.

[0004] Regarding the technologies mentioned above, existing general-purpose computing device protection cases generally suffer from insufficient heat dissipation performance. Although some products have basic ventilation measures, the lack of dedicated active cooling devices makes it difficult to dissipate heat quickly after prolonged use, potentially causing overheating and damage to the equipment, thus hindering effective heat dissipation. Utility Model Content

[0005] To overcome the above problems, this application provides a vehicle-mounted communication terminal and system.

[0006] The vehicle-mounted communication terminal and system provided in this application adopt the following technical solution:

[0007] Firstly, a vehicle-mounted communication terminal includes:

[0008] A general-purpose computing device, wherein the general-purpose computing device is used to receive or send instructions based on a communication terminal;

[0009] A protective case includes a case body, a placement assembly, a closing assembly, and a heat dissipation assembly. The top of the case body is open, and a connecting frame is coaxially connected to the opening. The placement assembly includes a placement component, which includes a placement plate and multiple placement rods. The placement plate is perpendicular to the axis of the case opening. The sidewall of the placement plate fits against the sidewall of the connecting frame. One side of the placement plate near the case opening is connected to the connecting frame. A placement slot for placing a general-purpose computing device is provided in the middle of the placement plate. The placement slot extends through the placement plate along its thickness. Multiple placement rods are connected to the placement slot. The placement rods are perpendicular to the axis of the case opening and support the general-purpose computing device.

[0010] The closing assembly includes a closing plate for opening or closing the enclosure opening. One side of the closing plate is hinged to one side of the enclosure opening. The hinge point between the closing plate and the enclosure and the connection point between the placement plate and the connecting frame are located near the two opposite side walls of the enclosure. A buffer groove for placing the general-purpose computing device is provided in the middle of the closing plate. The heat dissipation assembly includes a heat dissipation component, which includes two cooling fans. Both cooling fans are connected to the placement rod near the bottom of the enclosure. The two cooling fans can dissipate heat from the general-purpose computing device. Multiple heat dissipation holes are provided on both opposite sides of the enclosure.

[0011] By adopting the above technical solutions, effective protection and convenient use of general-purpose computing devices are achieved. Specifically, the hinged design of the closing plate allows the cabinet to be opened and closed flexibly, while the presence of the buffer groove further enhances the protection of the general-purpose computing devices. The cooling fan is installed on the mounting rod near the bottom of the cabinet, and together with multiple ventilation holes on both sides of the cabinet, an efficient airflow path is formed, significantly improving heat dissipation performance and effectively preventing damage to the general-purpose computing devices due to overheating, thus facilitating heat dissipation for the general-purpose computing devices.

[0012] In one specific implementation, the heat dissipation assembly further includes a cooling component located on the side of the placement plate near the bottom of the housing. The cooling component includes a cooling tank, a cooling pipe, and a water pump. The cooling tank is connected to the bottom of the housing and is used to hold coolant. Both ends of the cooling pipe are connected to the cooling tank, and the cooling tank and the cooling pipe form a closed loop. The section of the cooling pipe outside the cooling tank is S-shaped, and the water pump is connected to the cooling pipe.

[0013] By adopting the above technical solutions, the heat dissipation performance of this general-purpose computing device protection box has been significantly improved. Specifically, the addition of cooling components enables an effective liquid circulation cooling system to be formed inside the box. The S-shaped design of the cooling pipes extends the cooling path, increases the heat exchange area, and improves heat dissipation efficiency. Meanwhile, the water pump ensures that the coolant continuously flows in a closed loop, quickly removing the heat generated by the general-purpose computing device. These features work together to solve the problem of insufficient heat dissipation caused by traditional protection boxes relying solely on passive cooling, effectively avoiding the risk of equipment damage due to overheating, thereby improving the equipment's operational stability and service life.

[0014] In one specific implementation, the placement plate is hinged to the connecting frame on one side near the opening of the housing, and the placement plate is rotatable about the side on which it is hinged to the connecting frame;

[0015] The placement assembly also includes a lifting member located on the side of the placement plate near the bottom of the housing. The lifting member includes two lifting rods and two sliding seats. The two lifting rods are arranged in a cross configuration and are hinged together at their middle parts. The two lifting rods form a cross plane that is perpendicular to the bottom of the housing. Each of the two lifting rods has a hinge block hinged to one end. The hinge block is slidably connected to the end of the placement plate away from the rotation axis of the placement plate. Each sliding seat corresponds to one of the lifting rods. The other end of each of the two lifting rods is hinged to one of the sliding seats. The sliding seats are slidably connected to the bottom of the housing. The sliding direction of the sliding seats is consistent with the rotation axis of the placement plate. The two sliding seats move toward or away from each other.

[0016] By adopting the above technical solution, the placement plate can be rotated via a hinge, thereby adjusting its angle relative to the horizontal plane. The lifting mechanism further enhances the adjustability; two cross-arranged lifting rods work together to generate a lever effect as the sliding seat moves along the bottom of the enclosure, effectively pushing the placement plate to rotate. This design not only allows the placement plate to be flexibly adjusted to a suitable angle in different scenarios but also significantly improves operational convenience and optimizes the user experience. Furthermore, the structure is compact and rational, easily integrated into existing enclosure frames, and possesses high practical value.

[0017] In one specific implementation, the closure assembly further includes a connector and a transmission component. The connector includes two connecting rods, each located on one side of the opening of the housing. The two connecting rods are distributed along the rotation axis of the closure plate. One end of each connecting rod is hinged to the closure plate, and the other end is connected to the housing.

[0018] The transmission component includes a first rack, a first gear, a transmission rod, a first bevel gear, a double-acting screw, a second bevel gear, and a blocking rod. A sliding groove is formed on each of the two sides of the housing opening, and each groove corresponds to a connecting rod. The first rack is located in one of the sliding grooves and slides along the direction of the groove. The other end of the connecting rod is hinged to the first rack. The first gear is located at the end of the sliding groove near the closing plate and is rotatably connected to the housing. The first rack meshes with the first gear. A connecting cavity communicating with the sliding groove is formed on the side of the housing opening near the first gear. The transmission rod is connected to the bottom of the housing. Vertically, one end of the transmission rod is coaxially fixed to the first gear, and the other end is coaxially fixed to the first bevel gear. The transmission rod is rotatably connected to the housing. The first bevel gear and the second bevel gear are both located in the connecting cavity. The bidirectional screw is arranged along the sliding direction of the two sliding seats. The bidirectional screw is rotatably connected to the bottom of the housing. Each of the two sliding seats is threaded to one end of the bidirectional screw. The end of the bidirectional screw near the first bevel gear passes through the housing and extends into the connecting cavity, where it is coaxially fixed to the second bevel gear. The second bevel gear and the first bevel gear mesh. The blocking rod is connected to the housing and is used to fix the first rack.

[0019] By adopting the above technical solution, the connecting and transmission components enable the opening of the closing plate and the tilting state of the placement plate to be linked. Specifically, when the closing plate is opened, the connecting rod drives the first rack to move within the slide groove, thereby driving the first gear to rotate. This rotation is transmitted to the first bevel gear via the transmission rod, and further drives the second bevel gear to rotate through meshing. The rotation of the second bevel gear causes the bidirectional screw to rotate, thereby causing the two sliding seats to move towards or in opposite directions. This movement ultimately acts on the lifting component, pushing the placement plate to rotate around its hinge point, forming a suitable operating angle, facilitating the user's operation of the general-purpose computing device. Simultaneously, the design of the blocking rod can fix the position of the first rack in a specific state, ensuring the stability of the entire structure. Therefore, this design not only improves ease of use but also enhances the functionality and user experience of the protective box.

[0020] In one specific implementation, the placement assembly further includes two fixing members, both of which are located within the placement slot. The two fixing members are distributed along the rotation axis of the placement plate. Each fixing member includes a fixing plate and a fixing source. The fixing plate is slidably connected to the placement plate. The two fixing plates move toward each other or away from each other. A clamping area for placing the general-purpose computing device is provided between the two fixing plates. The fixing source is connected to the placement plate and is connected to the fixing plate to drive the fixing plate to move.

[0021] By adopting the above technical solution, the two fixing components can be distributed in the placement slot along the rotation axis of the placement plate, allowing the two fixing plates to move towards or away from each other, thereby forming a clamping area for placing general-purpose computing devices. This design achieves effective fixation of general-purpose computing devices of different sizes, improving compatibility and stability. Specifically, the cooperation between the fixing source and the fixing plate ensures reliable execution of the fixing action, avoids the risk of damage caused by equipment shaking, and enhances the safety of the protective case during transportation.

[0022] In one specific implementation, the fixing source includes a fixing rod, two hinged rods, and two springs. The fixing rod is located on the side of the fixing plate near the groove wall of the placement groove, and is parallel to the fixing plate. The placement plate has a receiving groove in the placement groove for placing the fixing rod. Both ends of the fixing rod are fixed to the placement plate. The two hinged rods are located between the fixing plate and the fixing rod, and are distributed in a cross pattern. The two hinged rods are hinged to each other at the middle, and form a cross plane parallel to the placement plate. One end of each hinged rod is hinged to a hinge seat, which is slidably connected to the fixing plate. The other end of each hinged rod is slidably connected to the fixing rod. The springs correspond one-to-one with the hinged rods. Each spring is sleeved on one end of the fixing rod, with one end of the spring fixed to the fixing rod and the other end fixed to the hinged rod.

[0023] By adopting the above technical solution, the fixed source can effectively achieve stable clamping of general-purpose computing devices. Specifically, the fixed rod, as a support structure, cooperates with the receiving groove on the placement plate to ensure the stability of the entire device. Two hinged rods are distributed in a cross pattern and connected by springs, forming an elastic drive mechanism that allows the fixed plate to move flexibly in the horizontal direction, thus adapting to general-purpose computing devices of different sizes. When an external force is applied to bring the fixed plates closer together, the springs are compressed to store energy; after the external force is removed, the springs return to their original shape, pushing the fixed plates back to their initial position. This design ensures both a uniform distribution of clamping force and avoids equipment damage caused by excessive compression. At the same time, the cross-arranged hinged rods also enhance the overall rigidity of the structure, further improving the safety of the protective box during transportation.

[0024] In one specific implementation scheme, a cleaning component is also included, which includes multiple dust filters, each corresponding to one of the heat dissipation holes. The dust filters are located inside the heat dissipation holes on the side closer to the inside of the housing, and are connected to the housing.

[0025] By adopting the above technical solutions, the dustproof net can effectively prevent external dust from entering the enclosure, avoid dust accumulation affecting the normal use and heat dissipation efficiency of the heat dissipation holes, and at the same time ensure a clean environment inside the enclosure, extending the service life of general-purpose computing equipment.

[0026] In one specific implementation, the cleaning assembly further includes two dustproof components, each located on opposite sides of the housing, near the heat dissipation holes. Each dustproof component includes a dustproof plate, a cleaning source, and multiple extension rods. Dustproof grooves are formed on opposite sides of the housing near the heat dissipation holes, and the multiple heat dissipation holes communicate with the dustproof grooves. The dustproof plate is parallel to the side wall of the housing and fits into the dustproof grooves. The dustproof plate is slidably connected to the housing, and the two dustproof plates move towards or away from each other. The cleaning source is connected to the housing and connected to the dustproof plate to drive its movement. The multiple extension rods are connected to the side of the dustproof plate near the housing, and each extension rod corresponds to a heat dissipation hole. Brush bristles are fixedly bonded to the side wall of each extension rod. When the general-purpose computing device is not needed, the extension rods extend into the heat dissipation holes.

[0027] By adopting the above technical solution, the dustproof component can extend into the heat dissipation holes via an insertion rod when general-purpose computing equipment is not in use, effectively preventing external dust from entering the heat dissipation holes and the interior of the enclosure. This avoids dust accumulation affecting heat dissipation performance and normal equipment operation. Simultaneously, the dustproof plate is parallel to the side wall of the enclosure and fits snugly within the dustproof groove, ensuring a tight seal and further enhancing protection. Furthermore, the cleaning source drives the dustproof plate's movement, allowing the bristles on the insertion rod to clean the edges of the heat dissipation holes during movement, keeping the heat dissipation channels unobstructed and improving the overall reliability and service life of the equipment.

[0028] Secondly, a vehicle-mounted communication system includes a vehicle-mounted communication terminal, a general-purpose computing terminal, a first data communication terminal, and a second data communication terminal; the vehicle-mounted communication terminal includes a general-purpose computing device and a protective box.

[0029] The first data communication terminal is used to send a communication pairing identifier corresponding to the target communication mode to the target vehicle terminal;

[0030] The second data communication terminal is used to verify the communication pairing identifier and establish a communication connection between the first data communication terminal and the second data communication terminal when the second data communication terminal of the target vehicle terminal has a target communication module corresponding to the target communication mode.

[0031] The general-purpose computing terminal is used to receive a first data packet corresponding to an operation instruction when a communication connection based on the target communication mode is established between the first data communication terminal and the second data communication terminal, and to transmit the first data packet to the second data communication terminal after preprocessing it, so as to send it to the target vehicle terminal.

[0032] By adopting the above technical solution, the vehicle communication system sets up a system in which the first data communication terminal sends a communication pairing identifier corresponding to the target communication mode to the second data communication terminal for communication verification. This enables the first and second data communication terminals to perform identity verification of the vehicle terminals within the system when making communication connections in complex environments. This is beneficial for building a multi-layered verification and protection system for data packet transmission within the system and improving the security of data transmission.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. The designed protective box for general-purpose computing devices features a cooling fan mounted on the mounting rod near the bottom of the box. Combined with multiple ventilation holes on both sides of the box, this creates an efficient airflow path, significantly improving heat dissipation performance and effectively preventing damage to the general-purpose computing devices due to overheating. This design also facilitates heat dissipation for the general-purpose computing devices.

[0035] 2. The designed universal computing device protection box solves the problem of insufficient heat dissipation caused by traditional protection boxes relying solely on passive heat dissipation, effectively avoiding the risk of equipment damage due to overheating, thereby improving the operational stability and service life of the equipment.

[0036] 3. The designed protective case for general-purpose computing devices utilizes a movement mechanism that ultimately acts on the lifting component, causing the placement plate to rotate around its hinge point, creating a suitable operating angle for convenient user operation of the general-purpose computing device. Simultaneously, the design of the barrier rod can fix the position of the first rack in specific states, ensuring the stability of the entire structure. Therefore, this design not only improves ease of use but also enhances the functionality and user experience of the protective case. Attached Figure Description

Detailed Implementation

[0045] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0046] This application discloses a vehicle-mounted communication terminal and system.

A connecting frame 11 is provided at the opening of the box body 1, and the axis of the connecting frame 11 is coaxial with the axis of the opening of the box body 1. The connecting frame 11 is fixedly connected to the box body 1 by screws. The placement component 2 includes a placement member 21, two fixing members 22, and a lifting member 23. The placement member 21 includes a placement plate 211 and multiple placement rods 212. The placement plate 211 is located inside the box body 1, and the setting direction of the placement plate 211 is perpendicular to the axis of the opening of the box body 1. The side wall of the placement plate 211 is attached to the side wall of the connecting frame 11. The side of the placement plate 211 closest to the opening of the box body 1 is hinged to the connecting frame 11. The connecting frame 11 and the placement plate 211 are rotatable around the side that is hinged to the connecting frame 11. The placement plate 211 has a placement slot 2111 in the middle for placing a general-purpose computing device. The placement slot 2111 extends through the placement plate 211 along the thickness direction of the placement plate 211. Multiple placement rods 212 are located in the placement slot 2111 and are arranged parallel to each other. The direction of the placement rods 212 is perpendicular to the direction of the opening axis of the housing 1. There is a gap between two adjacent placement rods 212. Both ends of the placement rods 212 are welded to the placement plate 211. The multiple placement rods 212 can support the general-purpose computing device.

[0049] Reference Figure 1 and Figure 2Both fixing members 22 are located within the placement slot 2111, and are distributed along the rotation axis of the placement plate 211. Each fixing member 22 is close to one of the two opposite walls of the placement slot 2111. Each fixing member 22 includes a fixing plate 221 and a fixing source 222. The fixing plate 221 is slidably connected to the placement plate 211. The two fixing plates 221 move toward or away from each other. A clamping area for placing a general-purpose computing device is provided between the two fixing plates 221. Each of the two devices is fixedly bonded with a flexible pad on one side to reduce wear on the general-purpose computing device when the fixing plate 221 clamps it. The fixing source 222 includes a fixing rod 2221, two hinge rods 2222, and two springs 2223. The fixing rod 2221 is located on the side of the fixing plate 221 near the groove wall of the placement groove 2111. The fixing rod 2221 is arranged parallel to the fixing plate 221. The placement plate 211 has a container in the placement groove 2111 for placing the fixing rod 2221. The slot 2112 has two ends of the fixing rod 2221 welded to the placement plate 211. Two hinged rods 2222 are located between the fixing plate 221 and the fixing rod 2221, arranged in a crisscross pattern with their middle sections hinged together. The two hinged rods form a plane parallel to the placement plate 211. One end of each hinged rod 2222 is hinged to a hinge seat, which is slidably connected to the fixing plate 221. The other ends of both rods are slidably connected to the fixing rod 2221. Spring 2223 corresponds one-to-one with hinge rod 2222, and each of the two springs 2223 is sleeved on one end of fixed rod 2221. One end of spring 2223 is welded to fixed rod 2221, and the other end is welded to hinge rod 2222. When the general computing device is placed between the two fixed plates 221, one end of the two hinge rods 2222 on fixed rod 2221 moves away from each other. At this time, both springs 2223 are in a compressed state. In this embodiment, spring 2223 is a compression spring.

The sliding seat 232 is slidably connected to the bottom of the box 1, and the sliding direction of the sliding seat 232 is consistent with the rotation axis direction of the placement plate 211. The two sliding seats 232 move toward each other or away from each other. When the two sliding seats 232 move toward each other, the two lifting rods 231 can push the placement plate 211 to rotate, so that the placement plate 211 is tilted, thereby facilitating the use of the general computing equipment by personnel.

[0051] Reference Figure 1 , Figure 3 and Figure 4 The closing assembly 3 includes a closing plate 31, a buffer 32, a connecting member 33, and a transmission member 34. The closing plate 31 is located at the opening of the housing 1. One side of the closing plate 31 is hinged to one side of the opening of the housing 1. The hinge point between the closing plate 31 and the housing 1 and the hinge point between the placement plate 211 and the connecting frame 11 are close to the two side walls directly opposite the housing 1. The closing plate 31 can open or close the opening of the housing 1. A buffer groove 311 for placing a general-purpose computing device is provided in the middle of the closing plate 31. The buffer 32 is a buffer pad, which is fixedly glued. Located near the side of the enclosure 1, the closing plate 31 closes the opening of the enclosure 1. When the closing plate 31 closes the opening of the enclosure 1, the buffer pad contacts the placement plate 211, which can reduce the wear between the closing plate 31 and the placement plate 211, thereby protecting the general computing device from damage. The connector 33 includes two connecting rods 331, which are located on opposite sides of the opening of the enclosure 1 and are distributed along the rotation axis of the closing plate 31. One end of the connecting rod 331 is hinged to the closing plate 31, and the other end is connected to the enclosure 1.

The first rack 341 is located in one of the sliding grooves 12 and can slide along the direction of the sliding groove 12. The other end of the connecting rod 331 is hinged to the first rack 341. The first gear 342 is located at the end of the sliding groove 12 near the closing plate 31. The first gear 342 rotates to connect... A first rack 341 meshes with a first gear 342, and a connecting cavity is provided on the side of the opening of the housing 1 near the first gear 342. The connecting cavity communicates with the slide groove 12. A transmission rod 343 is perpendicular to the bottom of the housing 1. One end of the transmission rod 343 is coaxially welded to the first gear 342, and the other end is coaxially welded to the first bevel gear 344. The transmission rod 343 is rotatably connected to the housing 1. The first bevel gear 344 and the second bevel gear 346 are both located in the connecting cavity. A bidirectional screw 345 is close to the bottom of the housing 1 and is arranged along the sliding direction of the two sliding seats 232. The bidirectional screw 345 is rotatably connected to the bottom of the housing 1. Each thread is connected to one end of the bidirectional screw 345. The sliding seat 232 can slide along the length of the bidirectional screw 345. The end of the bidirectional screw 345 near the first bevel gear 344 passes through the housing 1 and extends into the connecting cavity. The end of the bidirectional screw 345 located in the connecting cavity is coaxially welded to the second bevel gear 346. The second bevel gear 346 and the first bevel gear 344 mesh. The housing 1 has multiple blocking holes 13 on the side of the opening near the first gear 342. The blocking holes 13 communicate with the slide groove 12. The multiple blocking holes 13 are arranged along the setting direction of the slide groove 12. When the first rack 341 moves to the appropriate position, the blocking rod 347 passes through the blocking hole 13 and is inserted into the first rack. The first rack 341 has a toothed groove, and the blocking rod 347 is located in the slide groove 12. One end of the blocking rod 347 is provided with a mating part that matches the toothed groove of the first rack 341. The blocking rod 347 is interference-fitted with the blocking hole 13. When it is necessary to open the closing plate 31, firstly, the blocking rod 347 is pulled out and the closing plate 31 is rotated. At this time, the connecting rod 331 drives the first rack 341 to move. The first rack 341 drives the first bevel gear 344 to rotate through the first gear 342. Subsequently, the second bevel gear 346 drives the bidirectional screw 345 to rotate, which enables the two sliding seats 232 to move, thereby lifting the placement plate 211 and making the placement plate 211 tilted, which is convenient for personnel to use the general computing equipment.

[0053] Reference Figure 5The closing assembly 3 also includes two locking members 35, which are distributed along the rotation axis of the closing plate 31.

[0057] The implementation principle of a vehicle-mounted communication terminal and system according to an embodiment of this application is as follows: A general-purpose computing device is placed in advance on the placement component 21 of the placement assembly 2, and fixed by the fixing component 22. When the general-purpose computing device needs to be used, the housing 1 is placed on a flat surface. Then, the locking component 35 is activated, rotating the closing plate 31. At this time, the closing plate 31 drives the connecting component 33 to move. The connecting component 33 can drive the lifting component 23 to move through the transmission component 34. During the movement of the lifting component 23, it can push the placement plate 211 to rotate, placing the placement plate 211 in a suitable tilt position, facilitating the use of the general-purpose computing device. Meanwhile, the dustproof component 52 is activated, causing it to open the heat dissipation hole 15. After a period of use, when the temperature inside the cabinet 1 is measured by the control component 43 to be higher than the preset value, the control component 43 drives the heat dissipation component 41 and the cooling component 42 to dissipate heat from the inside of the cabinet 1 and the general computing device. After the general computing device is used, the closing plate 31 is closed. At this time, the blocking rod 347 is pulled out, and the connecting rod 331 drives the lifting component 23 to move through the transmission component 34 until the closing plate 31 closes with the cabinet 1. At this time, the placement plate 211 fits with the connecting frame 11, and the dustproof component 52 is activated again, causing it to fit with the dustproof groove 16.

[0058] Secondly, a vehicle-mounted communication system includes a vehicle-mounted communication terminal, a general-purpose computing terminal, a first data communication terminal, and a second data communication terminal; the vehicle-mounted communication terminal includes a general-purpose computing device and a protective box.

[0059] The first data communication terminal is used to send a communication pairing identifier corresponding to the target communication mode to the target vehicle terminal;

[0060] The second data communication terminal is used to verify the communication pairing identifier and establish a communication connection between the first data communication terminal and the second data communication terminal when the second data communication terminal of the target vehicle terminal has a target communication module corresponding to the target communication mode.

[0061] A general-purpose computing terminal is used to receive a first data packet corresponding to an operation command when a communication connection based on a target communication mode is established between a first data communication terminal and a second data communication terminal. After preprocessing the first data packet, it is transmitted to the second data communication terminal to be sent to the target vehicle terminal.

[0062] In this embodiment, a user interaction first subsystem is installed in the first general-purpose computing terminal. This user interaction first subsystem is used to establish a communication connection based on a target communication mode between the first vehicle-mounted terminal and the target vehicle-mounted terminal. In response to an operation command from the user, it uploads a first data packet corresponding to the operation command to the first general-purpose computing terminal. The first general-purpose computing terminal preprocesses the first data packet and then transmits it to the first data communication terminal. The first data communication terminal then reprocesses the first data packet based on the transmission requirements corresponding to the target communication mode to generate a second data packet. Finally, the first data communication terminal transmits the second data packet to the data communication terminal of the second vehicle (target vehicle-mounted terminal) based on the communication link of the target communication mode. The data communication terminal then sends the data to the user interaction second subsystem of the target vehicle-mounted terminal for data reception, thereby realizing data transmission between vehicles. Here, the first data packet can be any one or more of text messages, images, and videos.

[0063] The user interaction first subsystem of this application embodiment is compatible with different operating systems (such as mainstream operating systems like Windows and Linux). In this application embodiment, after establishing a communication connection based on the target communication mode between the first vehicle terminal and the target vehicle terminal, the user interacts with the first subsystem using a preset username, password, and verification code. If the username, password, and verification code are all verified, the transmission link corresponding to the first data packet is activated to transmit the first data packet. The general-purpose computing terminal of each vehicle communication terminal uses a high-performance processor with a multi-core structure, resulting in high operating speed and low power consumption.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
