Description

Technical Field

[0001] This invention relates to the field of communication terminal technology, specifically to a BeiDou integrated communication terminal and communication system. Background Technology

[0002] The integrated communication terminal is a core terminal device that relies on satellite navigation and short message communication technology to realize field positioning, emergency communication, and data backhaul. It is widely used in scenarios such as field exploration, emergency rescue, outdoor operations, geological exploration, and communication support in remote areas.

[0003] Existing terminals mostly have fixed, exposed antennas. Because the antennas are exposed for long periods, they are prone to bending, damage, dust accumulation, and moisture during carrying, bumping, and dropping. This seriously affects the stability of signal reception, shortens the service life of the equipment, and reduces its practicality. At the same time, the field operation environment is complex, and the equipment is prone to being dropped, bumped, or struck. Conventional shells cannot effectively absorb the impact energy, which can easily cause problems such as screen breakage, shell deformation, and loosening and damage to internal circuits. Therefore, we propose a Beidou integrated communication terminal and communication system. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a BeiDou integrated communication terminal and communication system, which solves the problems that existing communication terminals mostly have fixed and exposed antenna structures, which are easily damaged, have poor signal stability, and have weak overall drop and impact resistance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a Beidou integrated communication terminal, comprising a body, a display screen mounted on the surface of the body, a button mounted on the side of the body near the display screen, an antenna assembly mounted on the upper end of the body, the antenna assembly comprising an antenna outer cylinder inserted into the body, an inner antenna slidably inserted inside the antenna outer cylinder, and a first compression spring mounted on the inner bottom wall of the antenna outer cylinder, the upper end of the first compression spring extending into the antenna outer cylinder and connected to its inner top wall; The corners of the body are equipped with protective components. A placement slot is provided on the side of the body away from the display screen, and a battery is placed in the placement slot. A sealing component is provided on the side of the body near the battery. The device has a built-in BeiDou dual-mode signal processing unit, which is electrically connected to an RNSS positioning receiver module and an RDSS short message transceiver module. The antenna assembly is electrically connected to the BeiDou dual-mode signal processing unit to achieve integrated transmission of positioning, timing, and short message data. Before operation, the operator rotates the sealing cover at the top of the antenna outer cylinder to disengage the sealing cover from the threaded structure of the antenna outer cylinder. At this time, the first compression spring inside the antenna outer cylinder releases its elastic thrust, pushing the inner antenna upward, causing it to slide upward along the inside of the antenna outer cylinder, thus completing the antenna deployment. The terminal can then perform BeiDou positioning and communication operations normally. The structure of the antenna assembly, corner energy-absorbing protection assembly, and battery sealing assembly works together to provide comprehensive protection from three dimensions: signal transmission and reception quality, shock resistance, and power supply sealing performance. This enhances the terminal's adaptability to complex environments and ensures that the BeiDou positioning and communication fusion function can be stably output under various field conditions.

[0006] Preferably, the top of the antenna outer tube extends outside the machine body, and the upper surface of the antenna outer tube is provided with threads. A shaft is installed at the upper end of the inner antenna, and a sealing cover is rotatably installed on the shaft. The sealing cover is threaded onto the antenna outer tube, and several protrusions are installed circumferentially on the outer side of the sealing cover. Through the cooperation of the threaded sealing cover and the first compression spring, the inner antenna can be quickly and automatically deployed and manually retracted and locked. During operation, the inner antenna can be quickly deployed and the optimal signal transmission and reception height can be obtained, ensuring the continuous and stable signal link of Beidou positioning, timing and short message communication, supporting the reliable operation of Beidou integrated communication function. When idle, it can be completely retracted and sealed to avoid long-term exposure, impact, dust accumulation and oxidation damage to the antenna, greatly extending the antenna's service life, while reducing the space occupied by the whole machine, making the equipment easy to carry and store.

[0007] Preferably, a stop is installed at the top of the shaft, and the outer diameter of the stop is larger than the outer diameter of the shaft, which restricts the sealing cover to rotate only on the shaft. After the operation is completed, the sealing cover is pressed down, which drives the inner antenna to retract and be stored inside the antenna outer cylinder. Then, the sealing cover is screwed in the opposite direction to lock the sealing cover threaded on the upper end of the antenna outer cylinder, thereby realizing the closed storage of the inner antenna, effectively protecting the antenna structure and avoiding damage when idle.

[0008] Preferably, the protective component includes a mounting groove located at the corner of the body. Two positioning grooves are mirror-imagely formed on the inner side of the mounting groove, and two sliding grooves are mirror-imagely formed within the positioning grooves. An elastic plate is placed within the mounting groove, with both ends of the elastic plate extending into the two positioning grooves. Sliding rods are mounted on both sides of the elastic plate, slidably connected to the sliding grooves. A support rod is mounted on one end of the elastic plate, and a protective plate is mounted on the end of the support rod furthest from the elastic plate. The protective plate is located outside the corner of the body. Through structural sliding and the deformation of a second compression spring, it absorbs impact kinetic energy, effectively buffering the impact force of a fall and preventing damage to the body, display screen, and internal circuitry. When the external force disappears, the second compression spring and the elastic plate elastically reset, causing the protective plate to automatically return to its initial position, ensuring the continued effectiveness of the protective structure.

[0009] Preferably, the protective plate is arc-shaped, and protrusions are evenly installed on the side of the protective plate away from the support rod. The surface of the protective plate has wire holes for threading wires, thereby enabling the machine to be carried.

[0010] Preferably, a second compression spring is installed at the end of the elastic plate away from the support rod. The end of the second compression spring away from the elastic plate is connected to the inner wall of the mounting groove. The arc-shaped protective plate, support rod, elastic plate and second compression spring form a multi-dimensional energy absorption structure. When the terminal is dropped or bumped, the impact load is absorbed by mechanical sliding and spring elastic deformation, effectively dissipating the kinetic energy of the drop. This significantly reduces the impact damage to the body, screen and internal circuits, effectively protects the internal Beidou dual-mode signal processing unit, antenna assembly and core components, and avoids communication interruption and positioning failure caused by impact. It significantly improves the risk resistance of Beidou communication when the terminal is in the field. After the external force is removed, the protective structure can automatically reset, ensuring long-term stable and effective protection function, and greatly improving the equipment's drop and impact resistance under complex field conditions.

[0011] Preferably, the sealing assembly includes a slot located on the side of the body near the placement slot. A cover plate is inserted into the slot, located on one side of the battery. Locking bolts are inserted into the corners of the cover plate. The slot has threaded grooves adapted to the locking bolts. The cover plate, sealing strip, and limiting groove work together to achieve airtight protection of the battery compartment, effectively preventing external moisture and dust from entering the body, improving the overall waterproof and dustproof performance, ensuring the continuity of power supply and operational stability of the Beidou module, and supporting the terminal to maintain Beidou integrated communication online for a long time in harsh outdoor environments.

[0012] Preferably, a limiting groove is provided in the card slot, and a sealing strip is installed on the side of the cover plate near the battery. The sealing strip is adapted to the limiting groove. After the battery is assembled, the cover plate is reattached and the locking bolts are tightened. The sealing strip is used to compress and seal the battery, ensuring that the battery is installed stably and has good sealing performance. At the same time, when the body is placed on a flat surface, the protective frame at the corners can form a support structure to avoid direct friction and wear on the bottom surface of the body, further improving the overall durability of the terminal.

[0013] Preferably, protective frames are installed at the corners of the cover plate. The protective frames are bent and have through holes on the side corresponding to the locking bolts. The outer diameter of the nut of the locking bolt is larger than the inner diameter of the through hole. By adopting a bolt locking structure with protective frames, the locking bolts will not fall off or be lost when the battery is disassembled or installed. This makes disassembly and assembly convenient, maintenance efficient, and ensures a firm and reliable seal after assembly, avoiding problems such as loose battery or poor contact.

[0014] A communication system for a BeiDou integrated communication terminal includes the aforementioned BeiDou integrated communication terminal, and also includes a BeiDou satellite navigation communication platform, a cloud data management platform, and a ground monitoring and dispatching terminal; The BeiDou satellite navigation communication platform is connected to the cloud data management platform. The BeiDou satellite navigation communication platform is used to realize positioning and timing, short message two-way communication and remote data transmission in areas without terrestrial network coverage. The cloud data management platform is used to receive, store and parse the location trajectory, device status, emergency messages and environmental monitoring data uploaded by each terminal, and complete data classification management, anomaly identification and information push. The cloud-based data management platform is connected to the ground monitoring and dispatch terminal. The ground monitoring and dispatch terminal is used by managers to view the online status, location information and operation data of each field terminal in real time, and can issue dispatch instructions, emergency command information and parameter configuration instructions to realize multi-terminal collaborative dispatch, remote monitoring and emergency communication support. The ground monitoring and dispatch terminal is connected to the BeiDou integrated communication terminal, which is connected to the BeiDou satellite navigation and communication platform. The BeiDou integrated communication terminal is used to collect operation location information, operation status data, and environmental data.

[0015] In summary, the technical effects and advantages of this invention are as follows: 1. In this invention, the inner antenna can be quickly and automatically deployed and manually retracted and locked by the threaded sealing cover and the first compression spring. During operation, the inner antenna can be quickly deployed and the optimal signal transmission and reception height can be obtained, ensuring the continuous and stable signal link of Beidou positioning and timing and short message communication, supporting the reliable operation of Beidou integrated communication function. When idle, it can be completely retracted and sealed to avoid long-term exposure, impact, dust accumulation and oxidation damage to the antenna, greatly extending the antenna's service life, while reducing the space occupied by the whole machine, making the equipment easy to carry and store.

[0016] 2. In this invention, an arc-shaped protective plate, a support rod, an elastic plate, and a second compression spring are used to form a multi-dimensional energy-absorbing structure. When the terminal is dropped or bumped, the impact load is absorbed by both mechanical sliding and spring elastic deformation, effectively dissipating the kinetic energy of the drop. This significantly reduces the impact damage to the body, screen, and internal circuits, effectively protecting the internal Beidou dual-mode signal processing unit, antenna assembly, and core components. It also prevents communication interruption and positioning failure caused by impact, significantly improving the risk resistance of Beidou communication during field operations. After the external force is removed, the protective structure can automatically reset, ensuring long-term stable and effective protection. This greatly enhances the equipment's drop and impact resistance under complex field conditions.

[0017] 3. In this invention, the battery compartment is sealed and protected by the cover plate, sealing strip and limiting groove. This effectively prevents external moisture and dust from entering the machine body, improves the waterproof and dustproof performance of the whole machine, ensures the power supply continuity and operation stability of the Beidou module, and supports the terminal to maintain the Beidou integrated communication online status for a long time in harsh outdoor environments. At the same time, the bolt locking structure with protective frame is adopted, so the locking bolts will not fall off or be lost when the battery is disassembled and installed. The disassembly and installation are convenient and the maintenance efficiency is high. After assembly, the lock is firmly locked and the seal is reliable, avoiding the problem of loose battery and poor contact.

[0018] 4. In this invention, the retractable antenna assembly, the corner energy absorption protection assembly, and the battery sealing assembly work together to provide comprehensive protection from three dimensions: signal transmission and reception quality, shock resistance, and power supply sealing performance. This enhances the terminal's adaptability to complex environments and ensures that the BeiDou positioning and communication fusion function can be stably output under various field conditions.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] refer to Figures 1-11The Beidou integrated communication terminal shown includes a body 1, a display screen 2 installed on the surface of the body 1, a button 3 installed on the side of the body 1 near the display screen 2, an antenna assembly 6 provided at the upper end of the body 1, the antenna assembly 6 including an antenna outer tube 61, the antenna outer tube 61 is inserted into the body 1, an inner antenna 62 is slidably inserted into the antenna outer tube 61, a first compression spring 66 is installed on the inner bottom wall of the antenna outer tube 61, the upper end of the first compression spring 66 extends into the antenna outer tube 61 and is connected to its inner top wall; Protective components 7 are provided on all corners of the body 1. A placement slot 4 is provided on the side of the body 1 away from the display screen 2. A battery 5 is placed in the placement slot 4. A sealing component 8 is provided on the side of the body 1 near the battery 5. The main body 1 has a built-in Beidou dual-mode signal processing unit, which is electrically connected to the RNSS positioning receiver module and the RDSS short message transceiver module. The antenna assembly 6 is electrically connected to the Beidou dual-mode signal processing unit to realize the fusion transmission of positioning, timing and short message data. Before the terminal is operated, the operator rotates the sealing cover 63 at the top of the antenna outer tube 61 to disengage the threaded structure of the sealing cover 63 from the antenna outer tube 61. At this time, the first compression spring 66 inside the antenna outer tube 61 releases the elastic thrust and pushes the inner antenna 62 upward, so that the inner antenna 62 slides upward along the inside of the antenna outer tube 61 to complete the antenna deployment. The terminal can then perform Beidou positioning and communication operations normally. The structure of the antenna assembly 6, the corner energy absorption protection assembly 7 and the battery 5 sealing assembly 8 works together to form a comprehensive guarantee from three dimensions: signal transmission and reception quality, shock resistance and protection capability, and power supply sealing performance. This together improves the terminal's adaptability to complex environments and ensures that the Beidou positioning and communication fusion function can be stably output in various field conditions.

[0023] The antenna outer tube 61 extends to the outside of the body 1 at its top end, and the upper surface of the antenna outer tube 61 is threaded. The upper end of the inner antenna 62 is equipped with a shaft 64, and a sealing cover 63 is rotatably installed on the shaft 64. The sealing cover 63 is threaded onto the antenna outer tube 61, and several protrusions 67 are installed circumferentially on the outer side of the sealing cover 63. Through the cooperation of the threaded sealing cover 63 and the first compression spring 66, the inner antenna 62 can be quickly and automatically deployed and manually retracted and locked. During operation, the inner antenna 62 can be quickly deployed and the optimal signal transmission and reception height can be obtained, ensuring the continuous and stable signal link of Beidou positioning, timing and short message communication, supporting the reliable operation of Beidou integrated communication function. When idle, it can be completely retracted and sealed to avoid long-term exposure, impact, dust accumulation and oxidation damage to the antenna, greatly extending the antenna's service life, while reducing the space occupied by the whole machine, making the equipment easy to carry and store.

[0024] The top of the shaft 64 is equipped with a stop 65. The outer diameter of the stop 65 is larger than that of the shaft 64, which restricts the sealing cover 63 to rotate only on the shaft 64. After the operation is completed, the sealing cover 63 is pressed down, which drives the inner antenna 62 to retract and be stored inside the antenna outer cylinder 61. Then, the sealing cover 63 is screwed in the opposite direction to lock the threads of the sealing cover 63 on the upper end of the antenna outer cylinder 61, thereby achieving the closed storage of the inner antenna 62, effectively protecting the antenna structure and preventing damage when idle.

[0025] The protective component 7 includes a mounting slot 71 located at the corner of the body 1. Two positioning slots 72 are mirror-imagely formed on the inner side of the mounting slot 71, and two sliding grooves 73 are mirror-imagely formed within the positioning slots 72. An elastic plate 75 is placed inside the mounting slot 71, with both ends of the elastic plate 75 extending into the two positioning slots 72. Sliding rods 710 are mounted on both sides of the elastic plate 75, slidably connected to the sliding grooves 73. A support rod 76 is mounted on one end of the elastic plate 75, and a protective plate 77 is mounted on the end of the support rod 76 furthest from the elastic plate 75. The protective plate 77 is located outside the corner of the body 1. Through structural sliding and the deformation of the second compression spring 74, it absorbs the impact kinetic energy, effectively buffering the impact force of the fall and preventing damage to the body 1, display screen 2, and internal circuitry. When the external force disappears, the second compression spring 74 and the elastic plate 75 elastically reset, causing the protective plate 77 to automatically return to its initial position, ensuring the continued effectiveness of the protective structure.

[0026] The protective plate 77 is arc-shaped, and protrusions 78 are evenly installed on the side of the protective plate 77 away from the support rod 76. The surface of the protective plate 77 has wire holes 79 for threading wires, so as to carry the body 1.

[0027] Among them, a second compression spring 74 is installed at the end of the elastic plate 75 away from the support rod 76. The end of the second compression spring 74 away from the elastic plate 75 is connected to the inner wall of the mounting groove 71. The arc-shaped protective plate 77, the support rod 76, the elastic plate 75 and the second compression spring 74 form a multi-dimensional energy absorption structure. When the terminal is dropped or bumped, the impact load is absorbed by mechanical sliding and spring elastic deformation, effectively dissipating the kinetic energy of the drop. This significantly reduces the impact damage to the body 1, screen and internal circuits, effectively protecting the internal Beidou dual-mode signal processing unit, antenna assembly 6 and core components. It avoids communication interruption and positioning failure caused by impact, significantly improving the risk resistance of Beidou communication when the terminal is in the field. After the external force is removed, the protective structure can automatically reset, ensuring the long-term stable and effective protection function, and greatly improving the equipment's drop and impact resistance under complex field conditions.

[0028] The sealing component 8 includes a slot 85, which is located on the side of the body 1 near the placement slot 4. A cover plate 81 is inserted into the slot 85, which is located on one side of the battery 5. Locking bolts 84 are inserted into the corners of the cover plate 81. A threaded groove 87 adapted to the locking bolts 84 is opened in the slot 85. The cover plate 81, the sealing strip 88 and the limiting groove 86 work together to achieve the airtight protection of the battery 5 compartment. This can effectively prevent external moisture and dust from entering the body 1, improve the waterproof and dustproof performance of the whole machine, ensure the power supply continuity and operational stability of the Beidou module, and support the terminal to maintain the Beidou integrated communication online status for a long time in harsh outdoor environments.

[0029] The card slot 85 has a limiting groove 86. A sealing strip 88 is installed on the side of the cover plate 81 near the battery 5. The sealing strip 88 is adapted to the limiting groove 86. After the battery 5 is assembled, the cover plate 81 is reattached and the locking bolt 84 is tightened. The sealing strip 88 is used to compress and seal the battery, ensuring that the battery 5 is installed firmly and has good sealing performance. At the same time, when the body 1 is placed on a flat surface, the protective frame 82 at the corners can form a support structure to avoid direct friction and wear on the bottom surface of the body 1, further improving the overall durability of the terminal.

[0030] The cover plate 81 is equipped with protective frames 82 at each corner. The protective frames 82 are bent and have through holes 83 on the side corresponding to the locking bolts 84. The outer diameter of the nut of the locking bolts 84 is larger than the inner diameter of the through holes 83. The bolt locking structure with protective frames 82 ensures that the locking bolts 84 will not fall off or be lost when the battery 5 is disassembled or installed. The disassembly and installation are convenient and the maintenance efficiency is high. After assembly, the locking is firm and the sealing is reliable, avoiding the problem of loose battery 5 and poor contact.

[0031] One of the communication systems of a Beidou integrated communication terminal includes the aforementioned Beidou integrated communication terminal, as well as a Beidou satellite navigation communication platform, a cloud data management platform, and a ground monitoring and dispatching terminal; The BeiDou satellite navigation communication platform is connected to the cloud data management platform. The BeiDou satellite navigation communication platform is used to realize positioning and timing, short message two-way communication and remote data transmission in areas without terrestrial network coverage. The cloud data management platform is used to receive, store and parse the location trajectory, equipment status, emergency messages and environmental monitoring data uploaded by each terminal, and complete data classification management, anomaly identification and information push. The cloud-based data management platform is connected to the ground monitoring and dispatch terminal. The ground monitoring and dispatch terminal is used by managers to view the online status, location information and operation data of each field terminal in real time, and can issue dispatch instructions, emergency command information and parameter configuration instructions to realize multi-terminal collaborative dispatch, remote monitoring and emergency communication support. The ground monitoring and dispatch terminal is connected to the Beidou integrated communication terminal, which in turn is connected to the Beidou satellite navigation and communication platform. The Beidou integrated communication terminal is used to collect operation location information, operation status data, and environmental data.

[0032] The operation flow of a Beidou integrated communication terminal communication system is as follows: S1. Terminal-side signal fusion processing and data acquisition: The terminal is centered on a Beidou dual-mode signal processing unit, and together with antenna assembly 6, RNSS positioning and receiving module, and RDSS short message transceiver module, it forms a complete signal transceiver link.

[0033] Antenna assembly 6 is responsible for bidirectional transmission and reception of BeiDou satellite signals: In receiving mode, the antenna captures satellite signals sent by the BeiDou satellite navigation and communication platform and sends them to the BeiDou dual-mode signal processing unit; the unit schedules the RNSS positioning receiving module to solve the satellite navigation message and outputs the terminal's real-time position coordinates and standard timing information, while simultaneously scheduling the RDSS short message transceiver module to parse the satellite downlink short message data, scheduling instructions and emergency information, and completes the fusion calculation of positioning and communication signals to achieve integrated output of positioning and communication. In transmitting mode, the operational status data, environmental monitoring data and emergency messages collected by the terminal are encoded and encapsulated by the BeiDou dual-mode signal processing unit and then sent uplink to the BeiDou satellite navigation and communication platform in the form of short messages through antenna assembly 6.

[0034] S2, Data Interaction and Intelligent Processing: As a space relay node, the BeiDou satellite navigation and communication platform broadcasts navigation and positioning signals and downlink short messages to terminals across the entire domain. On the other hand, it receives uplink short message data and positioning reporting information from each terminal and forwards them to the cloud data management platform. The cloud-based data management platform serves as the system's data hub: it performs distributed storage and classification management of location trajectories, device operating status, and business data reported by massive terminals. Through built-in trajectory analysis algorithms and anomaly recognition models, it automatically identifies and sends early warnings for terminal statuses such as boundary crossing, offline, low battery, and malfunctions. At the same time, it performs protocol conversion, target addressing, and data encapsulation for instructions issued by ground monitoring and dispatch terminals, and then sends them to the corresponding terminals via the BeiDou satellite navigation and communication platform, realizing bidirectional data relay and intelligent processing across the entire link.

[0035] S3, Ground Dispatch and Terminal Closed-Loop Management: The ground monitoring and dispatch terminal synchronously pulls the real-time location, operating status, alarm information and operation data of all online terminals from the cloud data management platform, and visualizes the distribution and operating status of terminals across the entire domain through electronic maps, data lists and other forms. Managers send dispatch instructions, parameter configurations, and emergency command information to designated terminals or terminal groups through ground monitoring and dispatch terminals. After the instructions are verified and packaged by the cloud data management platform, they are pushed to the target terminal through the Beidou satellite link. After the terminal receives and executes the instructions, it transmits the execution results and the latest status information back to the ground end along the original link, forming a closed-loop control and realizing multi-terminal collaborative operation and remote emergency command.

[0036] The retractable antenna structure, corner buffer protection structure, and battery 5 sealing component 8 of the terminal together ensure the stable operation of the equipment under complex field conditions, ensuring that the Beidou signal link is continuously online and data acquisition and reporting are uninterrupted, providing reliable terminal-side support for the entire communication system.

[0037] Working principle of this invention: This Beidou integrated communication terminal integrates a retractable antenna assembly 6, a corner buffer protection assembly 7, and a battery sealing assembly 8. The three components work together to ensure the stable operation of the terminal's Beidou positioning and communication functions in field conditions. Before terminal operation, the operator rotates the sealing cover 63 at the upper end of the antenna outer tube 61 to disengage the sealing cover 63 from the threaded structure of the antenna outer tube 61. At this time, the first compression spring 66 inside the antenna outer tube 61 releases its elastic thrust and pushes the inner antenna 62 upward, causing the inner antenna 62 to slide upward along the inside of the antenna outer tube 61 and complete the antenna deployment. After the inner antenna 62 is fully extended, the optimal signal transmission and reception height can be obtained, ensuring the stable reception and transmission of Beidou RNSS positioning signals and RDSS short message signals, and providing a hardware foundation for the positioning and communication fusion function. After the operation is completed, the sealing cover 63 is pressed down to drive the inner antenna 62 to retract and be stored inside the antenna outer tube 61. Then, the sealing cover 63 is screwed in the opposite direction to lock the threads of the sealing cover 63 at the upper end of the antenna outer tube 61, realizing the closed storage of the inner antenna 62, effectively protecting the antenna structure and avoiding damage when idle. If the terminal is dropped or bumped during daily carrying or operation, the protective components 7 at the four corners of the body 1 can achieve efficient buffering protection. When the corner of the body 1 hits the ground or a foreign object, the arc-shaped protective plate 77 first contacts the force and transmits the impact force to the elastic plate 75 through the support rod 76. The two ends of the elastic plate 75 slide along the slide groove 73 through the slide rod 710, and at the same time squeeze the second compression spring 74 to undergo elastic deformation. Through the structural sliding and the deformation of the second compression spring 74, the impact kinetic energy is absorbed together, effectively buffering the impact force of the drop and avoiding damage to the body 1, the display screen 2 and the internal circuit. The protective component 7 effectively avoids the antenna component 6 from deformation and the internal Beidou dual-mode signal processing unit from desoldering damage caused by the drop impact, prevents the communication link from being interrupted unexpectedly, and ensures that the terminal can still maintain the Beidou communication function under the condition of bumping and dropping. When the external force disappears, the second compression spring 74 and the elastic plate 75 elastically reset, driving the protective plate 77 to automatically return to the initial position, ensuring that the protective structure continues to be effective. The terminal's battery 5 adopts a rear-mounted embedded installation structure, relying on the sealing component 8 to achieve waterproof and dustproof sealing and reliable fixation. During daily use, the cover plate 81, together with the sealing strip 88, is inserted into the limiting groove 86, forming an all-round sealing protection for the battery 5 placed inside the slot 4, preventing moisture and dust from entering the body 1. When replacing the battery 5, a tool is inserted through the through hole 83 of the protective frame 82, and the locking bolts 84 are loosened one by one, so that the locking bolts 84 are disengaged from the threaded groove 87. The bolts and nuts are limited by the protective frame 82 and will not fall off or be lost. After all the bolts are loosened, the cover can be removed. The cover plate 81 is used to complete the disassembly and replacement of battery 5. After battery 5 is assembled, the cover plate 81 is reattached and the locking bolts 84 are tightened. The sealing strip 88 is used to compress and seal the battery, ensuring that battery 5 is installed firmly and has good sealing performance. At the same time, when the body 1 is placed on a flat surface, the protective frame 82 at the corners can form a support structure to avoid direct friction and wear on the bottom surface of the body 1, further improving the overall durability of the terminal.
