Description

Technical Field

[0001] This invention relates to the field of BeiDou / GPS positioning and navigation application technology, specifically to a vehicle-mounted high-precision positioning device that integrates BeiDou and GPS dual-mode. Background Technology

[0002] The BeiDou Navigation Satellite System and GPS are global positioning and navigation systems independently developed by China and the United States, respectively. BeiDou + GPS dual-mode means that a navigation terminal can support both the BeiDou and GPS satellite navigation systems. More precisely, it means that both systems can run simultaneously on the navigation terminal to assist in positioning. In the automotive application market, navigation products supporting BeiDou / GPS dual-mode have become a common configuration. Vehicle terminals based on BeiDou and GPS positioning and navigation technologies need to improve positioning accuracy and communication capabilities, reduce power consumption, optimize performance, and ensure reliability. Most existing vehicle terminals are based on GPS navigation and positioning systems, requiring external communication through mobile communication networks. This means that when network signals are poor, the vehicle terminal cannot communicate with the outside world, and the received positioning information cannot be reported to the backend server, preventing the backend server from knowing the vehicle's location.

[0003] The XNAV620, a BD2 / GPS dual-mode navigation baseband receiver SOC chip, is an independently developed chip with complete independent intellectual property rights by the Xiamen University Haixi Communication Engineering Center. The chip supports single-mode positioning and dual-mode joint positioning modes using the BeiDou-2 B1 frequency and GPS L1 frequency. It is manufactured using a 130nm process and packaged in a QFN64 package. Key performance parameters include acquisition sensitivity of -144dBm, tracking sensitivity of -158dBm, and positioning accuracy (s). The XNAV620 can be applied to car navigation, dashcams, smartphones, and other handheld positioning devices.

[0004] For some vehicles, the positioning device built into the vehicle is prone to unstable connection when used for a long time or when the vehicle is driving on bumpy roads. Moreover, the accuracy of the positioning device in the current technology is difficult to be manually inspected and corrected due to deviations. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a vehicle-mounted high-precision positioning device that integrates BeiDou and GPS dual-mode to solve the problems mentioned in the background section. To achieve the above objectives, the present invention provides the following technical solution: a vehicle-mounted high-precision positioning device integrating BeiDou and GPS dual-mode, comprising: a mounting box, wherein a connecting main box is fixedly installed inside the mounting box; two sets of RNSS positioning modules and a BeiDou positioning module are respectively installed inside the left and right sides of the connecting main box; a mobile communication module and an embedded microprocessor are also installed inside the connecting main box; one end of the mounting box has a fixed plug-in end corresponding to the two sets of RNSS positioning modules and the BeiDou positioning module; two sets of connecting components are provided outside the plug-in ends of the mounting box; the connecting components respectively cover the periphery of the plug-in ends of the RNSS positioning module and the BeiDou positioning module; plug-in components are provided on both sides of the connecting components; the outer side of the mounting box... Two connecting wires are inserted into the part, and plugs are fixed at the insertion ends of the connecting wires. The plugs are selected to connect to a single RNSS positioning module and a Beidou positioning module to the vehicle system. The connecting assembly includes a sleeve frame, which is fitted around the plug-in ends of the RNSS positioning module and the Beidou positioning module. The bottom of the sleeve frame is hollowed out, and the top of the sleeve frame is covered with a cover plate. A fixing frame is set inside the sleeve frame, and the plug is fixed on the fixing frame. The connecting wire slides through the fixing frame and exits from the sleeve frame, and the connecting wire is fixed at the exit position of the sleeve frame. The plug-in assembly includes a sliding rod, and there are four sets of sliding rods. The four sets of sliding rods are arranged in pairs on both sides of the sleeve frame. The sleeve frame and the cover plate are fixed with collars on both sides, and the collars slide on the sliding rods.

[0006] Furthermore, the connecting assembly also includes: a second movable notch, a sliding plate, a bottom frame, and a guide plate. The guide plate is slidably inserted into the top of the fixing frame. The top of the sleeve frame away from the insertion end has a second movable notch. The sliding plate is slidably connected inside the second movable notch. The guide plate is fixed on the sliding plate. The bottom frame is fixed to the bottom of the fixing frame, and the bottom of the fixing frame slides along the inside of the bottom frame. A first electric push rod is fixed inside the sliding plate, and the extended end of the first electric push rod is fixedly connected to the fixing frame.

[0007] Furthermore, a sliding frame is fixed inside the sleeve corresponding to the position of the connecting wire, and a movable frame is slidably connected inside the sliding frame. A wire-passing block is rotatably installed inside the movable frame, and the connecting wire slides through the wire-passing block. A second spring is fixed to the inner wall of the sliding frame, and the other end of the second spring is fixedly connected to the movable frame.

[0008] Furthermore, the fixing frame is slidably inserted into the bottom of the guide plate, and a top rod is fixed to one end of the insertion plate facing the insertion end. A protective cover is rotatably installed at the top of the inlet of the insertion end through a rotating shaft and a torsion spring, and a protruding plate is fixed to the top of the protective cover. The top rod is in pressing contact with the protruding plate. A first spring is fixed to one end of the insertion plate facing the slide plate, and the other end of the first spring is fixedly connected to the slide plate.

[0009] Furthermore, inclined blocks are fixed on both sides of the insert plate near one end of the slide plate, and inclined plates are fixed on both sides of the sleeve frame located at the second moving notch. The inclined plates and inclined blocks are on the same plane. When the insert plate moves laterally with the fixing frame, the inclined blocks slide along the inclined surface of the inclined plates to push the insert plate toward the insertion end.

[0010] Furthermore, a second electric push rod is fixed on the inner walls of both sides of the mounting box corresponding to the protruding end of the first electric push rod. A square frame is fixed to the extended end of the second electric push rod, and a block is fixed on the surface of the first electric push rod, with the block inserted into the inside of the square frame. Inside the mounting box, a limit frame is fixed at the position where the two connecting wires pass through, and the connecting wires pass through the top of the limit frame.

[0011] Furthermore, the bottom of the mounting box is fixed with a bottom layer, and the bottom layer has a cavity inside. The top of the bottom layer has a communication port corresponding to the installation positions of the two sets of RNSS positioning modules and Beidou positioning modules. Two sets of heat dissipation boxes are symmetrically slidably installed inside the bottom layer, and small fans are installed inside the heat dissipation boxes. Dustproof nets are fixed at the front and rear ends of the bottom layer.

[0012] Furthermore, a first movable notch is provided at the bottom of the mounting box corresponding to the position of the square frame, a connecting plate is fixed at the bottom of the square frame, and the connecting plate slides along the first movable notch, and the bottom of the connecting plate is fixedly connected to the heat sink box.

[0013] Furthermore, the top two sides of the mounting box are rotatably mounted with box doors, and the top of the sliding rod near the inner wall of the two sides of the mounting box is provided with a pull rod, which is slidably inserted into the top of the box door; wherein, the bottom four corners of the cover plate are fixed with first inserts, and the top four corners of the sleeve frame are provided with first insertion holes, and the first inserts are inserted into the first insertion holes.

[0014] Furthermore, the plug-in assembly also includes: a second plug hole, a connecting rod, a second plug post, and a rotating seat. The bottom of the pull rod is fixed with a rotating seat, the bottom of the rotating seat is rotatably mounted with a connecting rod, the bottom of the connecting rod is fixed with a second plug post, and the two collars on the slide rod have second plug holes on the side facing the second plug post. The second plug post is inserted into one of the second plug holes. The box door has an adjustment groove corresponding to the pull rod's protruding end, and the pull rod slides out of the adjustment groove. A slider is slidably connected inside the adjustment groove, and the pull rod slides out of the slider. A third spring is fixed between the inner wall of the adjustment groove and the slider.

[0015] The beneficial effects of this invention are: When the mounting bracket and plug move, the wire threading block slides with the moving bracket and rotates with the position of the plug. During this process, the connecting wire can be limited, and the end of the connecting wire that enters the mounting box will not be pulled, thus avoiding loosening of the connecting wire and the vehicle system when the plug is replaced.

[0016] This invention uses a second electric push rod to drive the slide plate along the second movable notch, which in turn causes the fixing frame to slide inside the bottom frame. The position of the plug is adjusted to correspond to one of the plug-in ends. The first electric push rod pushes the vertical plate to slide along the guide plate, allowing the plug to be inserted into the plug-in end. This enables the connection between the vehicle system and the RNSS positioning module and Beidou positioning module inside the connection box. As the slide plate moves from one plug-in end to another, the inclined blocks on both sides of the plug plate slide into contact with the inclined plate on the corresponding side, allowing the plug plate to pass through the fixing frame. The top column presses against the convex plate on the protective cover, opening the protective cover and facilitating the insertion of the plug into the plug-in end. The other plug-in end is protected by the protective cover, preventing dust from entering.

[0017] This invention uses a frame to enclose the two plug-in ends of the RNSS positioning module and the Beidou positioning module. In the frame-enclosed state, the blocks on the surface of the first electric push rod are inserted into the corresponding blocks. The interlocking of the blocks can be easily facilitated by the second electric push rod to drive the slide plate along the second moving notch. At the same time, the blocks can separate from the frame as the frame moves upward without causing movement interference.

[0018] When the heat dissipation box moves to the bottom of the connection port, the RNSS positioning module and Beidou positioning module at the top are cooled. Here, the connecting plate slides along the first moving notch. When the position of the sliding plate inside the two sleeve frames and the position of the plug-in RNSS positioning module and Beidou positioning module are adjusted, the heat dissipation box will also move synchronously, so as to independently and efficiently cool the RNSS positioning module and Beidou positioning module in use.

[0019] This invention protects the components inside the mounting box by covering the top of the mounting box with a cover plate. The second pin at the bottom of the connecting rod is inserted into the second insertion hole of the sleeve side collar. There are two operations for maintenance or disassembly. The first is that the second pin remains inserted in the second insertion hole of the sleeve side collar. When the box door is opened, the pull rod drives the rotating seat and connecting rod to rotate, causing the sleeve and cover plate to slide upwards along the slide rod, opening the insertion end of the main connecting box for easy maintenance. The second operation involves sliding the slider along the moving groove and pulling the pull rod upwards, moving the second pin to the position of the second insertion hole on the side collar of the cover plate. After releasing the pull rod, the slider moves along the adjusting groove due to the elastic force of the third spring, and the second pin inserts into the second insertion hole. When the box door is opened, the connecting rod only pulls the cover plate upwards along the slide rod, separating it from the sleeve frame, thus keeping the sleeve frame in its original position for maintenance of the internal structural components.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown in the figure, this disclosure proposes a vehicle-mounted high-precision positioning device that integrates BeiDou and GPS dual-mode, including: a mounting box 1, inside which a connecting main box 2 is fixed, and two sets of RNSS positioning modules and BeiDou positioning modules are respectively installed on the left and right sides of the connecting main box 2, and a mobile communication module and an embedded microprocessor are also installed inside the connecting main box 2, one end of the mounting box 1 is fixed with a plug-in terminal 21 corresponding to the two sets of RNSS positioning modules and BeiDou positioning modules, and two sets of connecting components 3 are arranged on the outside of the plug-in terminals 21 of the mounting box 1, the connecting components 3 respectively covering the periphery of the plug-in terminals 21 of the RNSS positioning modules and the BeiDou positioning modules, the connecting components 3 The mounting box 1 has two plug-in components 4 on both sides; two connecting wires 15 are inserted into the outside of the mounting box 1, and plugs 314 are fixed at the insertion ends of the connecting wires 15. The plugs 314 can be used to plug into a single RNSS positioning module and a Beidou positioning module to connect to the vehicle system; the connecting component 3 includes a sleeve 31, which is sleeved around the plug-in ends 21 of the RNSS positioning module and the Beidou positioning module. The bottom of the sleeve 31 is hollow, and the top of the sleeve 31 is covered with a cover plate 32. A fixing frame 313 is provided inside the sleeve 31, and the plug 314 is fixed on the fixing frame 313. The connecting wires 15 slide through the fixing frame 313 and exit from the sleeve 31, and connect... The connecting wire 15 is fixed at the protruding position of the sleeve frame 31; the plug-in assembly 4 includes a slide rod 41, which is provided in four sets. The four sets of slide rods 41 are arranged in pairs on both sides of the sleeve frame 31. The sleeve frame 31 and the cover plate 32 are fixed with collars 42 on both sides, and the collars 42 are slidably sleeved on the slide rods 41. When using the device, the connection box 2 is fixed inside the mounting box 1, and the connection assembly 3 is installed on the periphery of the RNSS positioning module and Beidou positioning module plug-in terminal 21. The plug 314 is plugged into one of the RNSS positioning module and Beidou positioning module to realize the connection between the vehicle system and the RNSS positioning module and Beidou positioning module. When the vehicle positioning has an error, By replacing the plug 314 with another set of plugs in the RNSS positioning module and the Beidou positioning module, it can be determined whether the problem lies in the RNSS positioning module and the Beidou positioning module or the vehicle system, thus making the repair more convenient. After opening the box door 14, the components inside the installation box 1 can be repaired, and the connecting component 3 can be disassembled. The embedded microprocessor stores the vehicle terminal positioning information sent by the RNSS positioning module into the positioning information buffer. According to the preset frequency, the vehicle terminal positioning information is extracted from the buffer and sent to the external terminal and the mobile communication module. The pseudorange differential positioning enhancement information is stored in the enhancement information buffer and forwarded to the RNSS positioning module.The RNSS positioning module receives BeiDou and GPS satellite navigation signals in real time. It acquires, tracks, despreads, and demodulates the navigation signals to obtain navigation messages and raw measurement information. Based on the raw measurement information, it calculates the satellite pseudorange information. It receives pseudorange differential positioning enhancement information from the embedded microprocessor, corrects the satellite pseudorange information using this enhancement, and calculates the vehicle terminal's positioning information based on the corrected pseudorange information and navigation messages. This positioning information is then sent to the embedded microprocessor. The mobile communication module forwards the vehicle terminal's positioning information to the positioning server, obtains differential positioning enhancement information from the positioning enhancement server, and sends it to the embedded microprocessor.

[0023] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in some embodiments, the connecting assembly 3 further includes: a second movable notch 35, a sliding plate 36, a bottom frame 312, and a guide plate 315. The guide plate 315 is slidably inserted into the top of the fixing frame 313. The top of the sleeve frame 31 on the side away from the insertion end 21 has a second movable notch 35. The sliding plate 36 is slidably connected inside the second movable notch 35. The guide plate 315 is fixed on the sliding plate 36. The bottom frame 312 is fixed to the bottom of the fixing frame 313, and the bottom of the fixing frame 313 slides along the inside of the bottom frame 312. A first electric push rod is fixed inside the sliding plate 36. 37, and the extended end of the first electric push rod 37 is fixedly connected to the fixed frame 313. Inside the sleeve 31, a sliding frame 319 is fixed at the position corresponding to the connecting wire 15, and a movable frame 320 is slidably connected inside the sliding frame 319. A wire-passing block 322 is rotatably installed inside the movable frame 320, and the connecting wire 15 slides through the wire-passing block 322. A second spring 321 is fixed to the inner wall of the sliding frame 319, and the other end of the second spring 321 is fixedly connected to the movable frame 320. The fixed frame 313 is slidably inserted with an insertion plate 316 at the bottom of the guide plate 315, and the insertion plate 316 faces the insertion end 2. One end of the connector 1 is fixed with a top rod 317. A protective cover 22 is rotatably mounted on the top of the inlet of the insertion end 21 via a rotating shaft and a torsion spring. A protruding plate 23 is fixed to the top of the protective cover 22, and the top rod 317 is in contact with the protruding plate 23. A first spring 318 is fixed to one end of the insertion plate 316 facing the slide plate 36, and the other end of the first spring 318 is fixedly connected to the slide plate 36. Inclined blocks 323 are fixed to both sides of the insertion plate 316 near the slide plate 36. Inclined plates 311 are fixed to both sides of the sleeve frame 31 located at the second moving notch 35. The inclined plates 311 and the inclined blocks 323 are on the same plane. When the insert plate 316 moves laterally with the fixing frame 313, the inclined block 323 slides along the inclined surface of the inclined plate 311 to push the insert plate 316 toward the insertion end 21. The mounting box 1 is fixed with a second electric push rod 310 on both sides of the inner wall corresponding to the protruding end of the first electric push rod 37. The extended end of the second electric push rod 310 is fixed with a square frame 39. The surface of the first electric push rod 37 is fixed with a block 38, and the block 38 is inserted into the square frame 39. The mounting box 1 is fixed with a limit frame 110 at the position where the two connecting wires 15 pass through, and the connecting wires 15 pass through the top of the limit frame 110.

[0024] Understandably, in this solution, there are two RNSS positioning modules and two Beidou positioning modules inside the connector box, one as a spare. The two plug-in terminals 21 of the RNSS and Beidou positioning modules are enclosed by a sleeve 31. With the sleeve 31 enclosing the module, the square 38 on the surface of the first electric push rod 37 inserts into the corresponding square 39. The engagement of the squares 38 allows the slide plate 36 to move along the second moving notch 35 via the second electric push rod 310. Simultaneously, the square 38 can separate from the square 39 as the sleeve 31 moves upwards without causing movement interference. Subsequently, the second electric push rod 310 can drive the slide plate 36 to slide along the second moving notch 35, thereby causing the fixing bracket 313 to slide along the bottom frame 312. Adjusting the position of the plug 314 corresponding to one of the plug-in terminals 21, the first electric push rod 37 pushes the vertical plate to slide along the guide plate 315, allowing the plug 314 to be inserted into the plug-in terminal 21, thus connecting the vehicle system to the connector box 2. The connection between the internal RNSS positioning module and the Beidou positioning module occurs as the slide plate 36 moves from one plug-in end 21 to another. The inclined blocks 323 on both sides of the plug plate 316 slide into contact with the corresponding inclined plate 311, allowing the plug plate 316 to pass through the fixing frame 313. The top post then presses against the protruding plate 23 on the protective cover 22, opening the protective cover 22 and facilitating the insertion of the plug 314 into the plug-in end 21. The other plug-in end 21 is protected by the protective cover 22, preventing... To prevent dust from entering the interior, the connecting wire 15 passes through the limiting bracket 110 and slides through the wire guide block 322. When the fixing bracket 313 and the plug 314 move, the wire guide block 322 slides with the moving bracket 320 and rotates with the position of the plug 314. During this process, the connecting wire 15 can be limited, and there will be no traction on the end of the connecting wire 15 that enters the mounting box 1, thus avoiding loosening of the connecting wire 15 and the vehicle system when replacing the plug terminal 21.

[0025] like Figure 2 and Figure 6 As shown, in some embodiments, the bottom of the mounting box 1 is fixed with a bottom layer 11, and the bottom layer 11 has a cavity inside. The top of the bottom layer 11 has a connecting port 19 corresponding to the installation positions of the two sets of RNSS positioning modules and the Beidou positioning module. Two sets of heat dissipation boxes 18 are symmetrically slidably installed inside the bottom layer 11, and a small fan is installed inside the heat dissipation box 18. The front and rear ends of the bottom layer 11 are fixed with dustproof nets 12. The bottom of the mounting box 1 has a first movable notch 16 corresponding to the position of the square 39. The bottom of the square 39 is fixed with a connecting plate 17, and the connecting plate 17 slides along the first movable notch 16. The bottom of the connecting plate 17 is fixedly connected to the heat dissipation box 18. The two sides of the bottom layer 11 are fixed with fixing plates 13.

[0026] It is understandable that the connecting port 19 can be understood as a heat-conducting plate. When the heat dissipation box 18 moves to the bottom of the connecting port, it dissipates heat from the RNSS positioning module and the Beidou positioning module at the top. Here, the connecting plate 17 slides along the first moving notch 16. When adjusting the position of the sliding plate 36 inside the two sleeve frames 31 and the position of the RNSS positioning module and the Beidou positioning module plugged into the plug 314, the heat dissipation box 18 will also move synchronously, thereby providing independent and efficient heat dissipation for the RNSS positioning module and the Beidou positioning module in use.

[0027] like Figure 9 and Figure 10 As shown, in some embodiments, box doors 14 are rotatably mounted on both sides of the top of the mounting box 1. A pull rod 47 is provided at the top of the sliding rod 41 near the inner walls on both sides of the mounting box 1, and the pull rod 47 is slidably inserted into the top of the box door 14. A first insertion post 33 is fixed at the four bottom corners of the cover plate 32, and a first insertion hole 34 is opened at the four top corners of the sleeve frame 31. The first insertion post 33 is inserted into the first insertion hole 34. The insertion assembly 4 further includes: a second insertion hole 43, a connecting rod 44, a second insertion post 45, and a rotating seat 46. The bottom of the pull rod 47 is fixed with the rotating seat 46. A connecting rod 44 is rotatably mounted on the bottom of the rotating seat 46. A second insert post 45 is fixed to the bottom of the connecting rod 44. Two collars 42 on the slide rod 41 have second insertion holes 43 on the side facing the second insert post 45. The second insert post 45 is inserted into one of the second insertion holes 43. An adjustment groove 48 is provided on the box door 14 corresponding to the protruding end of the pull rod 47. The pull rod 47 slides out of the adjustment groove 48. A slider 49 is slidably connected inside the adjustment groove 48, and the pull rod 47 slides out of the slider 49. A third spring 410 is fixed between the inner wall of the adjustment groove 48 and the slider 49.

[0028] It should be noted that when the cover plate 32 covers the top of the mounting box 1, it can protect the components inside the mounting box 1. At this time, the second insertion post 45 at the bottom of the connecting rod 44 is inserted into the second insertion hole 43 of the side collar 42 of the sleeve frame 31. There are two operations during maintenance or disassembly. The first is that the second insertion post 45 is still inserted into the second insertion hole 43 of the side collar 42 of the sleeve frame 31. At this time, when the box door 14 is turned to open, the pull rod 47 drives the rotating seat 46 and the connecting rod 44 to rotate, and the sleeve frame 31 and the cover plate 32 slide upward along the slide rod 41, opening the insertion end 21 of the connecting box 2. One method facilitates the maintenance of the main junction box 2. Another method involves sliding the slider 49 along the moving groove and pulling the pull rod 47 upward, causing the second insertion post 45 to move to the position of the second insertion hole 43 on the side collar 42 of the cover plate 32. After releasing the pull rod 47, the slider 49 moves along the adjusting groove 48 due to the elastic force of the third spring 410, and the second insertion post 45 is inserted into the second insertion hole 43. At this time, when the box door 14 is opened, the connecting rod 44 only pulls the cover plate 32 upward along the sliding rod 41, separating it from the sleeve frame 31, so that the sleeve frame 31 remains in its original position, allowing for the maintenance of the internal structural components of the sleeve frame 31.

[0029] Working principle: When using the device, the main connection box 2 is fixed inside the mounting box 1. The connecting assembly 3 is installed around the RNSS positioning module and the Beidou positioning module's connector 21. The plug 314 is then plugged into one of the RNSS and Beidou positioning modules to connect the vehicle system to them. When vehicle positioning errors occur, the plug 314 is replaced with the other connector to determine whether the problem lies with the RNSS and Beidou positioning modules or the vehicle system, thus facilitating troubleshooting. The two connectors 21 of the RNSS and Beidou positioning modules are enclosed by the sleeve 31. With the sleeve 31 in place... The square 38 on the surface of the first electric push rod 37 is inserted into the corresponding square frame 39. The engagement of the square 38 with the square 38 allows the slide plate 36 to move along the second moving notch 35 via the second electric push rod 310. At the same time, the square 38 can separate from the square frame 39 as the sleeve frame 31 moves upward without causing movement interference. Subsequently, the slide plate 36 can be slid along the second moving notch 35 via the second electric push rod 310, thereby causing the fixing bracket 313 to slide along the inside of the bottom frame 312. Adjusting the position of the plug 314 corresponding to one of the plug terminals 21, the first electric push rod 37 pushes the vertical plate to slide along the guide plate 315, allowing the plug 314 to be inserted into the plug terminal 21, realizing the connection between the vehicle system and the RNSS inside the connection box 2. The connection between the positioning module and the Beidou positioning module is achieved as the sliding plate 36 moves from one plug-in end 21 to another. The inclined blocks 323 on both sides of the plug plate 316 slide into contact with the corresponding inclined plate 311, allowing the plug plate 316 to pass through the fixing frame 313. The top post presses against the protruding plate 23 on the protective cover 22, opening the protective cover 22 and facilitating the insertion of the plug 314 into the plug-in end 21. The other plug-in end 21 is protected by the protective cover 22, preventing dust from entering. The connecting wire 15 passes through the limiting frame 110 and slides through the wire threading block 322. As the fixing frame 313 and the plug 314 move, the wire threading block 322 slides with the moving frame 320 and changes position with the plug 314. The rotation of 22 limits the connection wire 15 during this process, and prevents traction on the end of the connection wire 15 that passes through the mounting box 1, thus avoiding loosening of the connection wire 15 and the vehicle system when replacing the plug terminal 21. The connecting port 19 can be understood as a heat-conducting plate. When the heat dissipation box 18 moves to the bottom of the connecting port, it dissipates heat from the RNSS positioning module and Beidou positioning module at the top. Here, the connecting plate 17 slides along the first moving notch 16. When adjusting the position of the sliding plate 36 inside the two sleeve frames 31 and the position of the RNSS positioning module and Beidou positioning module plugged into the plug 314, the heat dissipation box 18 will also move synchronously, thereby providing independent and efficient heat dissipation for the RNSS positioning module and Beidou positioning module in use.The cover plate 32 covering the top of the mounting box 1 can protect the components inside the mounting box 1. At this time, the second insert 45 at the bottom of the connecting rod 44 is inserted into the second insertion hole 43 of the side collar 42 of the frame 31. There are two operations for maintenance or disassembly. The first is that the second insert 45 is still inserted into the second insertion hole 43 of the side collar 42 of the frame 31. At this time, when the box door 14 is turned to open, the pull rod 47 drives the rotating seat 46 and the connecting rod 44 to rotate, and the frame 31 and the cover plate 32 slide upward along the slide rod 41 to open the insertion end 21 of the connecting box 2, which is convenient for maintenance. One method for maintenance is to connect the main box 2. Another method involves sliding the slider 49 along the moving groove and pulling the pull rod 47 upwards, causing the second insertion post 45 to move to the position of the second insertion hole 43 on the side collar 42 of the cover plate 32. After releasing the pull rod 47, the slider 49 moves along the adjusting groove 48 due to the elastic force of the third spring 410, and the second insertion post 45 is inserted into the second insertion hole 43. At this time, when the box door 14 is opened, the connecting rod 44 only pulls the cover plate 32 upwards along the sliding rod 41, separating it from the sleeve frame 31. Thus, the sleeve frame 31 remains in its original position, allowing for maintenance of the internal structural components of the sleeve frame 31.
