Description

Technical Field

[0001] This utility model relates to the field of emergency rescue equipment technology, and more specifically, it relates to a satellite emergency rescue terminal. Background Technology

[0002] In emergency scenarios lacking terrestrial communication and power coverage, such as wilderness exploration, earthquake and flood disaster relief, and operations in remote areas, satellite emergency rescue terminals are core equipment for ensuring personnel safety. Their power supply stability directly determines the effectiveness of critical functions such as rescue signal transmission and location reporting. Currently, satellite emergency rescue terminals generally rely on solar power as their core endurance method. However, the existing solar power supply structure design has many unreasonable aspects, severely restricting its practicality and reliability in complex field environments. Specific defects are as follows: 1. In the existing solar power supply structure of satellite emergency rescue terminals, the solar panels mostly adopt a "fixed single panel" or "single-section folding" design, which cannot dynamically adjust the light-receiving angle and effective light-receiving area according to the sun's position, resulting in extremely low energy conversion efficiency. On the one hand, the solar panels are mostly directly fixed to the top surface of the terminal box, and can only receive sunlight at a fixed angle (usually 30°). However, the solar altitude angle in the field environment varies significantly with time (such as morning, noon, and evening) and region (such as low-latitude mountains and high-latitude plains). On the other hand, existing terminals are mostly equipped with only a single solar panel, and the area of ​​a single panel is generally less than 0.03㎡ (common size is 180mm×150mm). Moreover, it cannot be expanded due to the limited box size. Even on a sunny noon, the output power of a single panel is only 5~8W. In the case of cloudy or overcast conditions, the output power drops sharply to 1~2W, or even cannot drive the charging circuit, causing the terminal's main battery to continuously consume power. After 3~4 hours, it faces the risk of power outage and cannot support long-term emergency communication.

[0003] The existing solar panel support structure of the terminal mostly adopts the "external independent bracket" design, that is, the support components are separated from the terminal box. When using it, the bracket needs to be manually assembled and the solar panel is fixed on the bracket. This is not only cumbersome to operate, but also has the problems of easy loss and poor stability. Utility Model Content

[0004] The purpose of this invention is to provide a satellite emergency rescue terminal that effectively solves the problems of low light collection efficiency and poor adaptability of existing terminals, significantly improves energy collection capabilities in the field, and significantly improves field operation efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a satellite emergency rescue terminal, including a terminal box base and a terminal box cover; The rear top end of the terminal box base is hinged to the rear bottom end of the terminal box cover. The top of the terminal box cover is equipped with a first solar power generation panel and a second solar power generation panel. The bottom front end of the first solar power generation panel is hinged to the top front end of the terminal box cover, and the bottom rear end of the second solar power generation panel is hinged to the top rear end of the first solar power generation panel. The bottom surface of the terminal box cover is equipped with a display screen, and the top surface of the terminal box base is equipped with a control keyboard. The base of the terminal box is used to house the battery and electronic control components, and the first solar panel and the second solar panel are used to charge the battery.

[0006] As a preferred embodiment of this utility model, the bottom edge of the first solar power panel is provided with an extension edge, and a receiving cavity is formed by the extension edge. A telescopic rod is provided in the receiving cavity, and one end of the telescopic rod is rotatably connected to the rear end of the first solar power panel. The telescopic rod is a telescopic rod with a length locking structure.

[0007] As a preferred technical solution of this utility model, louvered heat dissipation windows are provided on both sides and the rear side of the terminal box base.

[0008] As a preferred embodiment of this utility model, the front side of the terminal box base is provided with a device opening, and a device drawer is configured inside the device opening.

[0009] As a preferred technical solution of this utility model, the terminal box base is provided with a lifting handle on both sides of the center, and the lifting handles on both sides are connected by a box body strap.

[0010] As a preferred embodiment of this utility model, the front side of the terminal box cover, the rear side of the first solar power panel, and the front side of the second solar power panel are all equipped with a lifting handle.

[0011] As a preferred embodiment of this utility model, the rear top end of the terminal box base and the rear bottom end of the terminal box cover, the front bottom end of the first solar power panel and the front top end of the terminal box cover, and the rear bottom end of the second solar power panel and the rear top end of the first solar power panel are all hinged by damping hinges.

[0012] As a preferred embodiment of this utility model, the front top of the terminal box base and the front bottom of the terminal box cover, the rear bottom of the first solar power panel and the rear top of the terminal box cover, the front bottom of the second solar power panel and the front top of the first solar power panel, and the front of the terminal box base and the front of the equipment drawer are all connected by connecting buckles.

[0013] As a preferred embodiment of this utility model, the connecting buckle includes a rotating shaft, a rotating buckle plate, and a positioning post. One end of the rotating buckle plate is provided with a through hole, and the rotating shaft is sleeved in the through hole. The other end of the rotating buckle plate is provided with a positioning groove that matches the positioning post. The rotating shaft and the positioning post are respectively fixedly installed on two objects to be fixed.

[0014] In summary, this utility model has the following beneficial effects: Through its structural design of dual solar panel hinges and adjustable-angle support, this utility model effectively solves the problems of low light-gathering efficiency and poor adaptability of existing terminals, significantly improving energy harvesting capabilities in outdoor environments. Specifically, the first and second solar panels hinged at the top of the terminal box cover can be unfolded into a V-shape via damping hinges. After unfolding, the overall light-gathering area reaches 0.06㎡, which is 100% higher than the existing single-panel structure. Simultaneously, the damping hinges support arbitrary angle stops within the adjustment range. Combined with the telescopic rod at the bottom of the first solar panel, personnel can adjust the two solar panels to the optimal light-gathering angle according to the sun's position and terrain slope, minimizing blind spots.

[0015] This invention significantly improves field operation efficiency and equipment durability through the integrated design of a telescopic rod with a built-in receiving cavity. Firstly, the extended edge of the bottom edge of the first solar panel forms the receiving cavity, allowing the telescopic rod to be fully embedded within it in its retracted state. No additional disassembly or storage of loose parts is required; simply pulling out the telescopic rod provides support, reducing operation time to less than 30 seconds. This improves assembly efficiency compared to existing external supports and perfectly meets the rapid power supply needs of emergency scenarios. Secondly, the telescopic rod and the receiving cavity are integrated, eliminating loose parts and preventing loss during transport. Attached Figure Description

[0041] Data export process: Connect the computer via the USB interface on the side of terminal box base (Figure 11). The main controller switches to data transmission mode, and the computer reads the historical distress records and location trajectories in Flash for rescue review.
