Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted positioning terminal technology, and in particular to a Beidou wired positioning terminal that is easy to fix in a vehicle. Background Technology

[0002] GPS vehicle positioning terminals are essential positioning system terminals in vehicle equipment. They are devices installed inside automobiles that have positioning, monitoring, and other functions.

[0003] A search revealed a Chinese utility model patent, publication number CN208239620U, with the patent name... The present invention relates to a GPS vehicle positioning terminal, which is equipped with a support frame and a pull-out box. The support frame can fix the positioning terminal to achieve the effect of front-facing installation, and the pull-out box makes it convenient to pull out the antenna when the signal is poor or the service is unavailable, which is beneficial to the normal driving of the vehicle and brings better use prospects.

[0004] However, in actual use, the above and similar technical solutions still have some problems: 1. When the current vehicle positioning terminal is physically damaged or the external interface connection fails, data extraction faces significant challenges. Due to the lack of a non-destructive access mechanism, the storage module must be obtained by forced disassembly. However, this process is prone to causing secondary mechanical damage, resulting in physical deformation or circuit breakage of the data storage medium (such as flash memory chip), which seriously threatens data integrity. 2. In vehicle fire scenarios caused by traffic accidents, the existing terminal fixing structure does not integrate thermal protection functions, and the equipment is continuously exposed to the flame environment, which significantly increases the risk of shell melting and internal component ablation. 3. The high-temperature environment caused by fire can lead to performance degradation of internal electronic components (such as changes in carrier mobility of semiconductor materials) and failure of physical structure (solder melting, PCB delamination). Current designs lack active cooling or passive heat dissipation enhancement mechanisms. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a vehicle-mounted Beidou wired positioning terminal that is easy to remove the data storage module and easy to fix for protection and cooling in a fire.

A push rod is slidably connected inside the terminal housing. One end of the push rod is rotatably connected to the rotating rod. The other end of the push rod is used to abut against the slider. The shell wall of the terminal housing is filled with heat insulation cotton.

[0010] The terminal housing is connected to a disassembly mechanism, which includes a fixing ring. The fixing ring is installed on the terminal housing, and the outside of the terminal housing is connected to the inside through the fixing ring. A rotating column is threaded onto the fixing ring, and the data storage module is rotatably connected to the rotating column.

[0011] A fixed frame is fixedly connected to the fixed box, a pressure block is slidably connected to the fixed frame, and a second knob is threadedly connected to the fixed frame. The end of the second knob is rotatably connected to the pressure block, and the pressure block abuts against the plug end of the external wiring.

[0012] A guide rod is fixedly connected to the fixed box, and the flip plate is movably connected to the guide rod. The guide rod is provided with a guide groove, and a guide block is fixedly connected to the flip plate. The guide block extends into the guide groove and is slidably connected to the guide rod through the guide groove.

A first memory spring is movably sleeved on the end of the slide rod away from the flip plate, and the two ends of the first memory spring are respectively fixed to the push block and the fixed box.

[0013] The fixed box is fixedly connected to a plug rod at one end away from the flip plate. The plug rod is inserted into the push block. The flip plate is provided with a plug hole. The plug rod is inserted into the flip plate through the plug hole. The guide rod is provided with an abutment groove. An abutment block is slidably connected to the flip plate. A second spring is installed between the abutment block and the flip plate. The abutment block extends into the abutment groove through the second spring. The abutment groove is arc-shaped.

[0014] A pair of baffles are fixedly connected to the flip plate, and the terminal housing is inserted between the pair of baffles. A first knob is threadedly connected to the baffle, and the threaded end of the first knob abuts against the outer wall of the terminal housing.

[0016] Compared with the prior art, the present invention provides a vehicle-mounted, easily fixed BeiDou wired positioning terminal, which has the following advantages: 1. This vehicle-mounted, easily fixed BeiDou wired positioning terminal features a positioning motherboard equipped with a sub-meter-level high-precision BeiDou positioning module. It can acquire real-time information such as the vehicle's position and speed. The data storage module stores relevant data. When the terminal housing is damaged and data cannot be read via external wiring, the rotating column can be rotated to unscrew it from the fixing ring. Since the data storage module rotates on the rotating column and is electrically connected to the positioning motherboard via a plug-in connection, it can be easily removed individually. This design facilitates the removal of the data storage module when the terminal housing is under pressure or damaged, eliminating the need for forced removal of the housing and making operation convenient.

[0017] 2. This vehicle-mounted Beidou wired positioning terminal, which is easy to fix, will cause the temperature of the fixing box to rise when a traffic accident causes the vehicle to catch fire. The first memory spring will deform and stretch due to the heat, pushing the push block to slide. The flip plate will be guided by the guide block and driven to rotate, ultimately flipping the terminal housing into the storage slot, so that it is stored inside the fixing box. This will prevent the fire source from directly contacting the terminal housing and play a protective role.

[0018] 3. This vehicle-mounted, easily fixed Beidou wired positioning terminal, when the internal temperature of the fixing box rises, causing the surface temperature of the terminal housing to rise, the heat insulation cotton first plays a role in heat insulation. If the high temperature still gradually seeps into the interior of the terminal housing, the second memory spring will extend due to heat, pushing the slider to slide under the guidance of the moving rod. The slider pushes the push rod, which in turn drives the pressure rod to press down through the rotating rod, triggering the pressure valve. The compressed nitrogen in the gas tank will then be slowly released. During the expansion and ejection process, the nitrogen will absorb a large amount of heat, thereby reducing the temperature of the enclosed space inside the terminal housing, protecting the internal electronic components, preventing them from being damaged due to overheating, and ensuring that the data can be successfully extracted later.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Example 1: Refer to Figures 1-9 A vehicle-mounted, easily fixed BeiDou wired positioning terminal includes a terminal housing 1, a positioning mechanism 2 connected to the terminal housing 1, and a positioning motherboard 25. The positioning motherboard 25 is installed inside the terminal housing 1. One end of the positioning motherboard 25 is plugged into an electrically connected data storage module 24. One end of the terminal housing 1 is plugged into an external wiring 21. One end of the terminal housing 1 is slidably connected to an adapter block 22. The adapter block 22 and the external wiring 21 are electrically connected by a plug-in connection. The adapter block 22 and the positioning motherboard 25 are electrically connected by an internal wiring 23. The positioning motherboard 25 is equipped with a sub-meter-level high-precision BeiDou positioning module, which facilitates the positioning of the vehicle's status.

[0024] In this invention, a disassembly mechanism 4 is connected to the terminal housing 1. The disassembly mechanism 4 includes a fixing ring 42. The fixing ring 42 is installed on the terminal housing 1. The outside of the terminal housing 1 is connected to the inside through the fixing ring 42. A rotating column 41 is threaded onto the fixing ring 42. The data storage module 24 is rotatably connected to the rotating column 41, which facilitates the quick removal of the storage module 24.

[0025] Example 2: Based on Example 1, a vehicle-mounted Beidou wired positioning terminal that is easy to fix is ​​provided. The terminal housing 1 is connected to a fixing mechanism 3. The fixing mechanism 3 includes a fixing box 317. The terminal housing 1 is equipped with the fixing box 317. The fixing box 317 is provided with a storage slot 33. The fixing box 317 is connected to a flip plate 34 at the top of the storage slot 33. The terminal housing 1 is connected above the flip plate 34, which facilitates the storage and protection of the terminal housing 1 in the event of a fire.

[0026] In this invention, a fixed frame 318 is fixedly connected to the fixed box 317, a pressure block 316 is slidably connected to the fixed frame 318, and a second knob 315 is threadedly connected to the fixed frame 318. The end of the second knob 315 is rotatably connected to the pressure block 316. The pressure block 316 abuts against the plug end of the external wiring 21. Rotating the second knob 315 pushes the pressure block 316 to slide downward, and the pressure block 316 abuts against the top of the external wiring 21, limiting the external wiring 21 so that the terminal housing 1 can be slidably pulled out of the external wiring 21, and preventing the external wiring 21 from affecting the rotation and storage of the terminal housing 1.

[0027] In this invention, a guide rod 39 is fixedly connected to the fixed box 317, and a flip plate 34 is movably connected to the guide rod 39. The guide rod 39 is provided with a guide groove 314, and a guide block 313 is fixedly connected to the flip plate 34. The guide block 313 extends into the guide groove 314 and is slidably connected to the guide rod 39 through the guide groove 314. A pair of slide rods 310 are fixedly connected to the fixed box 317, and the same push block 38 is slidably connected to the pair of slide rods 310. The push block 38 is slidably connected to the guide rod 39, and the end of the push block 38 is rotatably connected to the flip plate 34. A first memory spring 37 is movably sleeved on the end of the slide rod 310 away from the flip plate 34. The two ends of the first memory spring 37 are respectively fixed to the push block 38 and the fixed box 317, so that the first memory spring 37 can push the push block 38 and the flip plate 34 to slide when subjected to high temperature. The flip plate 34 is guided by the guide block 313 when sliding, so as to achieve flipping.

[0028] In this invention, a rod 311 is fixedly connected to the end of the fixing box 317 opposite to the flip plate 34. The rod 311 is inserted into the push block 38. The flip plate 34 is provided with a hole 312. The rod 311 is inserted into the flip plate 34 through the hole 312. The rod 311 is used to limit the flip plate 34 in the initial state to prevent the flip plate 34 from rotating in the initial state and reduce the pressure of the guide block 313. The guide rod 39 is provided with an abutment groove 319. An abutment block 32 is slidably connected to the flip plate 34. A second spring 321 is installed between the abutment block 320 and the flip plate 34. The abutment block 320 extends into the abutment groove 319 through the second spring 321. The abutment groove 319 is arc-shaped, thereby limiting the flip plate 34 and preventing the flip plate 34 from sliding due to the inertia of the car's movement in the initial state. When the first memory spring 37 deforms, it has a large thrust, which breaks through the limit of the abutment block 320, and the abutment block 320 disengages from the abutment groove 319, and the second spring 321 is compressed.

[0029] In this invention, a pair of baffles 35 are fixedly connected to the flip plate 34, and the terminal housing 1 is inserted between the pair of baffles 35. A first knob 36 is threadedly connected to the baffles 35. The threaded end of the first knob 36 abuts against the outer wall of the terminal housing 1, which facilitates the fixing of the terminal housing 1. By rotating the first knob 36, the threaded end of the first knob 36 can be driven to abut tightly against the outer wall of the terminal housing 1, thereby restricting the detachment of the terminal housing 1 and facilitating the disassembly and installation of the terminal housing 1.

[0030] In this invention, a limiting block 31 is slidably connected to the side wall of the fixing box 317. A first spring 32 is installed between the limiting block 31 and the fixing box 317. One end of the limiting block 31 extends into the interior of the fixing box 317 and is inclined. The limiting block 31 is used to abut against the push block 38, thereby preventing the first memory spring 37 from contracting and resetting due to the temperature drop after a fire, preventing the flip plate 34 from being pulled and flipped, preventing the terminal housing 1 from coming into contact with the fire sprinkler when exposed, and preventing damage to the circuit.

[0031] Example 3: Based on Example 2, a vehicle-mounted Beidou wired positioning terminal that is easy to fix has a cooling mechanism 5 connected to the terminal housing 1. The cooling mechanism 5 includes a gas tank 53. The gas tank 53 is installed inside the terminal housing 1, and cooling is achieved by releasing compressed gas through the gas tank 53.

[0032] In this invention, a slider 61 is slidably connected inside the terminal housing 1, and an adapter block 22 is installed on the slider 61. A moving rod 63 is fixedly connected to the slider 61, and the moving rod 63 is slidably connected to the terminal housing 1. A second memory spring 62 is movably sleeved on the moving rod 63. The two ends of the second memory spring 62 are respectively fixed to the terminal housing 1 and the slider 61, which facilitates pushing the slider 61 to move and provides a power source. At the same time, it drives the adapter block 22 to be retracted into the terminal housing 1 for protection. An abutment post 26 is slidably connected to the terminal housing 1. The bottom end of the abutment post 26 abuts against the slider 61. Pressing the abutment post 26 can limit the slider 61, which is convenient for limiting the slider 61.

[0033] In this invention, a closing mechanism 6 is connected to the terminal housing 1. The closing mechanism 6 includes a closing block 64. The closing block 64 is slidably connected to one end of the external wiring 21 inside the terminal housing 1. The sliding direction of the closing block 64 is perpendicular to the sliding direction of the slider 61. The slider 61 is provided with a sliding groove 66. The slider 61 is slidably connected to a connecting rod 65 through the sliding groove 66. The end of the connecting rod 65 away from the slider 61 is rotatably connected to the closing block 64, thereby driving the terminal housing 1 to close, reducing airflow, and slowing down the leakage of cold air inside the terminal housing 1.

[0034] In this invention, the gas cylinder 53 is filled with compressed nitrogen. A pressure valve 54 is installed at the outlet end of the gas cylinder 53. A pressure rod 56 is rotatably connected to the gas cylinder 53. One end of the pressure rod 56 abuts against the pressing end of the pressure valve 54. A rotating rod 55 is fixedly connected to the end of the pressure rod 56 away from the pressure valve 54. A push rod 52 is slidably connected inside the terminal housing 1. One end of the push rod 52 is rotatably connected to the rotating rod 55. The other end of the push rod 52 is used to abut against the slider 61. The shell wall of the terminal housing 1 is filled with heat insulation cotton 51, which facilitates the release of nitrogen from the gas cylinder 53. When the compressed nitrogen is released, it can absorb a large amount of heat, thereby cooling down. At the same time, the nitrogen can slow down the spread of fire and prevent it from burning into the fixed box 317.

[0035] Working principle: The fixed box 317 is bolted to the vehicle body. The positioning motherboard 25 inside is equipped with a sub-meter high-precision Beidou positioning module, which can obtain the position, speed and other information of itself and surrounding vehicles in real time. The system uses the Kalman filter algorithm to predict the future motion state of the vehicle and establishes a collision avoidance prediction model for calculation. When danger may occur, it will issue an early warning to the driver. The warning information is transmitted to the car host through the internal wiring 23, the adapter block 22 and the external wiring 21, and finally displayed on the car display screen. The data storage module 24 is used to store relevant data. When the terminal housing 1 is damaged and data cannot be read through the external wiring 21, the rotating column 41 can be rotated to make it unscrewed from the fixing ring 42. Since the data storage module 24 rotates on the rotating column 41 and is electrically connected to the positioning motherboard 25 by plugging, the data storage module 24 can be easily pulled out separately. This design makes it easy to remove the data storage module when the terminal housing 1 is pressured or damaged, without having to forcibly remove the housing, and the operation is convenient. When a traffic accident causes a vehicle fire, the temperature of the fixing box 317 rises. The first memory spring 37 inside (made of high-temperature nickel-titanium alloy, suitable for medium-high temperature environments; the first memory spring 37 deforms when the temperature exceeds 100℃) deforms and elongates due to the heat, pushing the push block 38 to slide. The push block 38 then pushes the flip plate 34, causing the guide block 313 fixed on the flip plate 34 to slide along the guide groove 314. The two ends of the guide groove 314 are strip-shaped segments distributed on both sides of the guide rod 39, while the middle section is an arc-shaped groove. This design allows the guide block 313 to first slide linearly along the strip-shaped segment of the guide groove 314, causing the flip plate 34 to disengage the terminal housing 1 from the external wiring 21 (the external wiring 21 is pulled out from the adapter block 22). When the guide block 313 moves to the guide groove... When the arc-shaped groove of 314 is reached, the flip plate 34 is driven to rotate, and the terminal housing 1 is flipped into the storage groove 33 and stored inside the fixing box 317, thereby preventing the fire source from directly contacting the terminal housing 1 and playing a protective role. The push block 38 continues to slide, and its front end and the end of the flip plate 34 together abut against the fixing box 317, thereby blocking the opening of the storage groove 33. At the same time, the push block 38 abuts against the inclined surface of the limiting block 31, pushing the limiting block 31 to slide and stretching the first spring 32. When the push block 38 slides past the limiting block 31, the first spring 32 pulls the limiting block 31 to reset, locking the push block 38 in the limiting position. This mechanism can prevent the first memory spring 37 from returning to its original state after the temperature drops and pulling the flip plate 34 back to its original position, thereby achieving continuous protection for the terminal housing 1. When the internal temperature of the fixing box 317 rises, causing the surface temperature of the terminal housing 1 to rise, the heat insulation cotton 51 first acts as heat insulation. If the high temperature continues to gradually penetrate into the terminal housing 1, the second memory spring 62 (made of the same high-temperature nickel-titanium alloy) will stretch due to heat and push the slider 61 to slide under the guidance of the moving rod 63. The movement of the slider 61 first causes the adapter block 22 to retract into the terminal housing 1. When the connecting rod 65 of the closing block 64 moves to the other end of the slide groove 66, the continued sliding of the slider 61 will pull the closing block 6 through the connecting rod 65. 4. Seal the socket of the external wiring 21 to reduce air convection inside and outside the housing. At the same time, the slider 61 pushes the push rod 52, which in turn drives the pressure rod 56 to press down through the rotating rod 55, triggering the pressure valve 54. The compressed nitrogen in the gas tank 53 is then slowly released. During the expansion and ejection process, the nitrogen absorbs a large amount of heat, thereby reducing the temperature of the enclosed space inside the terminal housing 1. The compressed nitrogen absorbs heat and cools down through the Joule-Thomson effect, protecting the electronic components and preventing them from being damaged due to overheating, ensuring that the data can be successfully extracted later.
