Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted communication equipment, in particular to a satellite communication terminal and a vehicle. Background Art

[0002] Currently, there are two ways to use satellite communication equipment. One is to use it in a portable and mobile manner with its own battery and operating system. In this way, the battery has a narrow temperature resistance range and cannot be carried on a vehicle for a long time. The other is to use satellite communication equipment using a high-orbit satellite system, which uses a vehicle-mounted battery to power the satellite communication equipment. In order to meet the receiving sensitivity of the high-orbit satellite antenna, the high-orbit satellite antenna needs to be arranged on the roof of the vehicle, and the high-orbit satellite receiving antenna cannot be built into the satellite communication equipment. When the satellite communication system is used on a vehicle, it needs to be connected to the high-orbit satellite antenna and use the high-orbit satellite antenna to receive satellite signals. When the satellite communication equipment is removed from the vehicle, it cannot be used because it cannot receive satellite signals through the high-orbit satellite antenna. From this, it can be seen that satellite communication equipment using a high-orbit satellite system cannot be removed from the vehicle for mobile use.

[0003] In other words, current satellite communication equipment either cannot be used on vehicles for a long time, or cannot be removed from the vehicle for mobile use, and cannot meet the needs of users for use in multiple scenarios both while driving and off the vehicle. Utility Model Content

[0004] In view of this, the utility model provides a satellite communication terminal and a vehicle to solve the problem that the current satellite communication equipment cannot meet the user's needs for multiple driving and leaving the vehicle.

[0005] In the first aspect, the utility model provides a satellite communication terminal, including a low-orbit satellite transceiver antenna 21, a low-orbit satellite transceiver baseband module 22, a functional module, a power management module 26 and a first shell; the low-orbit satellite transceiver baseband module 22 is connected to the low-orbit satellite transceiver antenna 21; the functional module is connected to the low-orbit satellite transceiver antenna 21; the power management module 26 is connected to the low-orbit satellite transceiver antenna 21, the low-orbit satellite transceiver baseband module 22 and the functional module; the first shell is arranged on the periphery of the low-orbit satellite transceiver antenna 21, the low-orbit satellite transceiver baseband module 22, the functional module and the power management module 26, and a first charging interface is provided on the first shell, and the power management module 26 is connected to the vehicle battery 15 or the external battery 12 through the first charging interface.

[0006] The utility model adopts a low-orbit satellite transceiver antenna 21 so that the satellite communication terminal can be fixed on the vehicle for a long time for use. The satellite communication terminal can also be quickly disassembled and used away from the vehicle when the user leaves the vehicle and walks to an uninhabited area. At the same time, it solves the problem that conventional mobile satellite communication equipment is not resistant to high and low temperatures, and the satellite communication equipment of the high-orbit satellite system needs to be connected to a vehicle-mounted antenna, thereby meeting the user's needs for rapid switching in multiple scenarios when driving and leaving the vehicle; it also has the advantages of high reliability and low antenna environment requirements.

Thus, it can be quickly connected to the vehicle battery 15 or the external battery 12. In an optional embodiment, the quick plug-in structure has a secondary lock.

[0009] Therefore, when the satellite communication terminal is connected to the vehicle battery 15 or the external battery 12 through the quick plug-in structure, it is necessary to manually press the secondary lock to remove it. This structure can ensure that the satellite communication terminal is not easy to fall off during use, especially when used in a vehicle.

[0010] In an optional implementation, the operating frequency band of the low-orbit satellite transceiver antenna 21 is: 1668-1675 MHz for uplink and 1518-1525 MHz for downlink.

[0011] This allows low-orbit satellite transceiver antennas to support narrowband communications.

[0012] In an optional implementation, the functional module includes one or more of the following: a navigation module 23 and a data processing and storage module 25 .

[0013] Because it can enable satellite communication terminals to support multiple kinetic energies.

[0014] In an optional implementation, the satellite communication terminal further includes a Bluetooth WiFi module 24 , and the Bluetooth WiFi module 24 is connected to the data processing and storage module 25 .

[0015] The Bluetooth WiFi module 24 can realize wireless data connection with the vehicle entertainment system or mobile phone, and the wireless connection can be convenient for users to quickly remove and use it away from the vehicle. The special satellite communication terminal itself may not have interactive capabilities, but is connected to the vehicle entertainment system or mobile phone through WiFi Bluetooth. The user can operate on the vehicle display screen or mobile phone screen to realize satellite phone calls or satellite SMS sending and receiving.

[0018] In an optional implementation, a second discharge interface 34 is further provided on the second housing, and the second discharge interface 34 is connected to the charge and discharge module 35 .

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0033] According to an embodiment of the present utility model, on the one hand, a satellite communication terminal is provided, such as Figure 1 and Figure 2 As shown, it includes a low-orbit satellite transceiver antenna 21, a low-orbit satellite transceiver baseband module 22, a functional module, a power management module 26 and a first shell; the low-orbit satellite transceiver baseband module 22 is connected to the low-orbit satellite transceiver antenna 21; the functional module is connected to the low-orbit satellite transceiver antenna 21; the power management module 26 is connected to the low-orbit satellite transceiver antenna 21, the low-orbit satellite transceiver baseband module 22 and the functional module; the first shell is arranged on the periphery of the low-orbit satellite transceiver antenna 21, the low-orbit satellite transceiver baseband module 22, the functional module and the power management module 26, and a first charging interface is provided on the first shell, and the power management module 26 is connected to the vehicle battery 15 or the external battery 12 through the first charging interface.

[0034] The low-orbit satellite transceiver antenna 21 is integrated inside the first housing and does not require external wiring. The antenna uses a low-orbit satellite circularly polarized omnidirectional antenna so that it does not need to be aligned with the satellite during use, ensuring the reliability of signal transmission and reception even if the vehicle changes direction while driving. The operating frequency band of the low-orbit satellite antenna is: uplink 1668~1675MHz, downlink 1518~1525MHz, and can support narrowband communication.

[0035] Low-orbit satellites are within 1,000 km from the ground, while high-orbit satellites operate at an altitude of 36,000 km, a distance difference of 36 times. In terms of distance loss, the signal strength received by the low-orbit satellite transceiver antenna is 30 dBm higher than that of the high-orbit satellite transceiver antenna, so the low-orbit satellite transceiver antenna can be designed to be smaller in size, with fewer restrictions on the layout position in the first shell, and can also be placed in the vehicle environment. At the same time, the number of low-orbit satellites in the future will far exceed that of high-orbit satellites, and the requirements for vehicle layout environment shielding are low. When high-orbit satellites are blocked by metal or other metal materials on the roof, the received signal strength is greatly attenuated, so when used in a vehicle, the antenna needs to be arranged in an environment where the roof is not blocked. However, due to the advantage of a large number of satellites, the low-orbit satellite antenna has little effect on the roof shielding, and is relatively suitable for layout in the vehicle. In terms of antenna size and layout position, high-orbit satellite terminals are not easy to disassemble and move when used in a vehicle.

[0036] The low-orbit satellite transceiver baseband module 22 realizes the function of satellite signal processing.

[0037] The power management module 26 implements the power-on and power-off logic management of the satellite communication terminal body 11. For example, different voltages and currents are provided to different modules; when the vehicle power supply needs to start with the vehicle, the power supply is controlled to start up and the vehicle power is turned off; when the external battery 12 is connected in the mobile state, the power is controlled to start up by pressing the power button, and the power is turned off by pressing the power button or removing the external battery 12.

[0038] The utility model adopts a low-orbit satellite transceiver antenna 21 so that the satellite communication terminal can be fixed on the vehicle for a long time for use. The satellite communication terminal can also be quickly disassembled and used away from the vehicle when the user leaves the vehicle and walks to an uninhabited area. At the same time, it solves the problem that conventional mobile satellite communication equipment is not resistant to high and low temperatures, and the satellite communication equipment of the high-orbit satellite system needs to be connected to a vehicle-mounted antenna, thereby meeting the user's needs for rapid switching in multiple scenarios when driving and leaving the vehicle; it also has the advantages of high reliability and low antenna environment requirements.

[0039] In one embodiment, the first charging interface adopts a quick plug-in structure. Specifically, the first housing can be waterproof and dustproof, and at the same time, the first housing has a quick plug-in structure, which is connected to the vehicle battery 15 when used on the vehicle, and matched with the external battery 12 when used off the vehicle. In this way, it can be quickly connected to the vehicle battery 15 or the external battery 12.

[0040] In one embodiment, the quick plug-in structure has a secondary lock. Therefore, when the satellite communication terminal is connected to the vehicle battery 15 or the external battery 12 through the quick plug-in structure, the secondary lock needs to be manually pressed to remove it. This structure can ensure that the satellite communication terminal is not easy to fall off during use, especially when used in a vehicle.

[0041] In one embodiment, the functional module includes one or more of the following: a navigation module 23 , a data processing and storage module 25 .

[0042] Specifically, the navigation module 23 is connected to the low-orbit satellite transceiver baseband module 22. The navigation module 23 can realize the terminal positioning function and can send location information in real time when an emergency is needed so that rescuers can find the person in need in time.

[0043] The data processing and storage module 25 is connected to the low-orbit satellite transceiver baseband module 22. The data processing and storage module 25 uses a processor and a storage chip with an operating system to realize data interaction and data processing with the vehicle entertainment system or mobile phone, and forwards it to the low-orbit satellite transceiver baseband module 22.

[0044] In one embodiment, the satellite communication terminal further includes a Bluetooth WiFi module 24, which is connected to a data processing and storage module 25. The Bluetooth WiFi module 24 can realize wireless data connection with an in-vehicle entertainment system or a mobile phone, and the wireless connection can facilitate users to quickly remove the device and use it outside the vehicle. The special satellite communication terminal itself may not have interactive capabilities, but is connected to an in-vehicle entertainment system or a mobile phone through WiFi Bluetooth. The user can operate on the in-vehicle display screen or the mobile phone screen to realize satellite phone dialing or satellite text message sending and receiving.

[0045] In one embodiment, Figure 3 As shown, the external battery 12 includes a battery cell 31, a charge and discharge module 35, and a second shell. The battery cell 31 is connected to the charge and discharge module 35. The second shell is arranged on the periphery of the battery cell 31 and the charge and discharge module 35. A first discharge interface 32 is arranged on the second shell. The first discharge interface 32 cooperates with the first charging interface. Thus, the external battery 12 can be connected to the first charging interface on the satellite communication terminal through the first discharge interface 32, and the satellite communication terminal is powered by the external battery 12. The first discharge interface 32 and the first charging interface are powered by metal contacts.

[0046] Specifically, the battery cell 31 does not need to be used in the vehicle and can use a conventional consumer battery to reduce costs. The charging and discharging module 35 provides support for charging the battery cell 31 and can also supply power to the outside through the first discharge interface 32 and the second discharge interface 34.

[0047] In one embodiment, the second housing of the external battery 12 is further provided with a second discharge interface 34, and the second discharge interface 34 is connected to the charge and discharge module 35. Specifically, the second discharge interface 34 is a USB-A interface. Thus, the external battery 12 can be connected to the mobile phone through the second discharge interface 34, and the external battery 12 is used to power the mobile phone.

[0048] In one embodiment, the second housing is further provided with a second charging interface 33, and the second charging interface 33 is connected to the charging and discharging module 35. Thus, the external battery 12 can be charged through the second charging interface 33. For example, the second charging interface 33 adopts a commonly used USB Type C interface or a Micro USB interface.

[0049] According to an embodiment of the present utility model, on the other hand, a vehicle is provided, including a vehicle battery 15 and the above-mentioned satellite communication terminal, wherein the vehicle battery 15 is connected to a first charging interface of the satellite communication terminal.

[0050] In summary, the utility model provides a pluggable vehicle-mounted low-orbit satellite communication terminal, which uses a separate battery and an integrated low-orbit satellite antenna and a low-orbit satellite module. It has the characteristics of high reliability, low antenna environment requirements, and support for high-speed mobile use. It also supports voice calls, short message sending, and network data sending. The terminal can realize the long-term fixed use of satellite communication equipment on the vehicle, and can also quickly disassemble the satellite communication equipment when the user leaves the vehicle and walks to an uninhabited area for use. At the same time, it solves the problem that conventional mobile satellite communication equipment is not resistant to high and low temperatures, and the satellite communication equipment of the high-orbit satellite system needs to be connected to the vehicle antenna, thereby meeting the user's needs for rapid switching in multiple scenarios when driving and leaving the vehicle.
