[0028] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0029] The purpose of this specific implementation is to provide a satellite communication portable station to solve the problems of low integration of satellite communication portable stations in the prior art and complicated and time-consuming installation process during use.

[0030] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention described in the claims. In addition, the entire contents of the configurations shown in the following embodiments are not limited to the solutions required as the invention described in the claims.

[0031] Reference Figures 1 to 7, showing a schematic diagram of the structure of a satellite communication portable station in some exemplary embodiments. A satellite communication portable station provided in this embodiment includes a host 1, a parabolic antenna 2, a base 3 and an adjustment bracket 4, wherein the vertex end of the parabolic antenna 2 is fixedly connected to the host 1. The base 3 is arranged horizontally, and the second end of the host 1 is rotatably connected to the second end of the base 3, and the rotation axis is arranged along the horizontal direction. By rotating the host 1 relative to the base 3, the inclination angle of the host 1 can be adjusted. The adjustment bracket 4 is arranged between the base 3 and the host 1, one end of the adjustment bracket 4 is rotatably connected to the first end of the base 3, and the other end is rotatably connected to the first end of the host 1. The adjustment bracket 4 can be telescopically adjusted in length, and the inclination angle of the host 1 can be adjusted by adjusting the length of the adjustment bracket 4. When the adjustment bracket 4 has a certain length, a triangular structure is formed between the adjustment bracket 4, the base 3 and the host 1; when the adjustment bracket 4 is extended, the distance between the first end of the host 1 and the first end of the base 3 increases, so that the angle between the host 1 and the base 3 increases, that is, the tilt angle of the host 1 increases; correspondingly, when the adjustment bracket 4 is shortened, the distance between the first end of the host 1 and the first end of the base 3 decreases, so that the angle between the host 1 and the base 3 decreases, that is, the tilt angle of the host 1 decreases; when the adjustment bracket 4 is shortened to the shortest, the adjustment bracket 4, the base 3 and the host 1 overlap. In this way, the parabolic antenna 2 is fixedly set on the host 1, and the host 1 is connected to the base 3 and the adjustment bracket 4 respectively, with high integration and no need for disassembly and assembly. When stored, the host 1, the base 3 and the adjustment bracket 4 can be overlapped by adjusting the adjustment bracket 4 to reduce the occupied space. When in use, the tilt angle of the host 1 only needs to be adjusted by the adjustment bracket 4, and no other installation steps are required, thereby avoiding a cumbersome installation process.

[0032] The host 1 is a portable station host, and a modulation and demodulation module, a low noise amplifier module, an up-conversion power amplifier module, and a control and display module are integrated in the housing of the host 1. The modulation and demodulation module, the low noise amplifier module, and the up-conversion power amplifier module are all connected to the control and display module for communication, and many functional modules are concentrated in the housing of the host 1. A display panel 17 and an external interface 18 are also provided on the housing of the host 1 to form a complete communication host. When using the satellite communication portable station, the disassembly and installation process between the high-frequency head, the up-conversion power amplifier, the modulation and demodulation module, and the connecting cable is omitted, which is convenient for use.

[0033] In this embodiment, the above-mentioned adjustment bracket 4 includes a first support plate 5, a second support plate 6 and a locking assembly, and the first support plate 5 and the second support plate 6 are arranged parallel to each other. Among them, the first end of the first support plate 5 is rotatably connected to the mainframe 1, and the second end of the second support plate 6 is relatively rotatably connected to the base 3. A slide rail structure is arranged between the first support plate 5 and the second support plate 6, so that the first support plate 5 can move relative to the second support plate 6 along the length direction of the second support plate 6. Through the relative movement between the first support plate 5 and the second support plate 6, the overall length of the adjustment bracket 4 can be adjusted. When the locking assembly is in the first state, the first support plate 5 and the second support plate 6 can move relative to each other, that is, the overall length of the adjustment bracket 4 can be changed; when the locking assembly is in the second state, the locking assembly limits the relative movement between the first support plate 5 and the second support plate 6, that is, the overall length of the adjustment bracket 4 is fixed and cannot be adjusted.

[0034] Specifically, the above-mentioned slide rail structure includes a first slide groove arranged on the first support plate 5, the extension direction of the first slide groove is consistent with the length direction of the first support plate 5, and the first end of the second support plate 6 can extend into the first slide groove and reciprocate along the length direction of the first slide groove.

[0035] During use, it is inevitable that dust or particles will enter between the second support plate 6 and the first chute, which will affect the relative sliding smoothness between the first support plate 5 and the second support plate 6. In practice, a sand discharge groove can be provided on the side wall of the first chute and the outer surface of the second support plate 6, and the dust or particles entering between the second support plate 6 and the first chute will be discharged through the sand discharge groove.

[0036] The above-mentioned locking assembly includes a locking screw 7 and a threaded through hole for the locking screw 7 to be screwed into. The threaded through hole is arranged on the side wall of the first slide groove on the first support plate 5. After the threaded end of the locking screw 7 is screwed into the threaded through hole on the first support plate 5, the end is pressed against the surface of the second support plate 6, thereby achieving the fixation of the relative position between the first support plate 5 and the second support plate 6, that is, the overall length of the adjustment bracket 4 is locked.

[0037] In practice, the adjustment bracket 4 further includes a fine adjustment component 8 disposed between the second end of the second support plate 6 and the base 3. After the overall length of the adjustment bracket 4 is roughly adjusted by adjusting the relative position between the first support plate 5 and the second support plate 6, the fine adjustment component 8 can be further adjusted, thereby improving the adjustment accuracy of the overall length of the adjustment bracket 4. The above-mentioned fine adjustment component 8 includes a first screw rod, a second screw rod and a connecting member that are coaxially arranged, wherein the first end of the first screw rod is fixedly connected to the second end of the second support plate 6, and the second end of the second screw rod is rotatably connected to the base 3, so as to ensure that the fine adjustment component 8 can rotate relative to the base 3. The thread rotation direction of the first screw rod is opposite to that of the second screw rod, and the connecting member is a columnar structure extending along the axial direction of the first screw rod and the second screw rod, and a first threaded hole threadedly matched with the second end of the first screw rod and a second threaded hole threadedly matched with the first end of the second screw rod are respectively arranged at both ends of the connecting member, and the first threaded hole and the second threaded hole can be connected. When the connecting member is rotated, the moving direction of the connecting member relative to the first screw is opposite to the moving direction of the connecting member relative to the second screw, that is, when the connecting member is rotated, the second end of the first screw and the first end of the second screw will approach each other or move away from each other, thereby adjusting the overall length of the bracket 4 to change.

[0038] In practice, the orientation of the host 1 and the parabolic antenna 2 can be adjusted by rotating the base 3 on the ground, which is called coarse adjustment.

[0039] In the preferred solution of this embodiment, the base 3 is configured to be two parts, including a first chassis 9 and a second chassis 10, which are arranged to overlap each other, the first chassis 9 is located above the second chassis 10, and the first chassis 9 and the second chassis 10 are rotatably connected, and the rotation axis is perpendicular to the plane where the first chassis 9 and the second chassis 10 are located. Generally, the first chassis 9 and the second chassis 10 are arranged horizontally, so the rotation axis of the first chassis 9 and the second chassis 10 relative to each other is arranged in the vertical direction, which can be specifically achieved by hinge connection. The adjustment bracket 4 and the host 1 are both connected to the first chassis 9. Without rotating the second chassis 10, the first chassis 9 is rotated relative to the second chassis 10, so that the orientation of the host 1 and the parabolic antenna 2 can be further adjusted.

[0040] In practice, an adjustment mechanism is provided between the first chassis 9 and the second chassis 10 to drive the first chassis 9 to rotate relative to the second chassis 10. The hinge point between the first chassis 9 and the second chassis 10 is located at the second end of the first chassis 9 and the second chassis 10, that is, the second end of the first chassis 9 is hinged to the second end of the second chassis 10. The above-mentioned adjustment mechanism is a gear rack transmission mechanism, such as Figure 4As shown, it includes a gear 11 and a rack 12 that can be meshed and transmitted. The gear 11 can be set in the form of a gear shaft. The axis of the gear 11 is set vertically and is rotatably connected to the first end of the second chassis 10. The rack 12 is arc-shaped and fixed to the first end of the first chassis 9. The center of the circle corresponding to the arc coincides with the hinge point between the first chassis 9 and the second chassis 10. When the gear 11 is rotated, the rack 12 drives the first chassis 9 to rotate on a fixed axis because the position of the gear 11 remains unchanged, so that the orientation of the host 1 and the parabolic antenna 2 will change relative to the second chassis 10. Adjustment is made through the gear 11 and the rack 12, and the adjustment accuracy is high. This type of adjustment is called fine adjustment.

[0041] A guide structure is also provided between the first chassis 9 and the second chassis 10, and the guide structure includes an arc groove 19 provided on the second chassis 10 and a slider 20 provided on the first chassis 9. The arc groove 19 is arc-shaped, and the corresponding center coincides with the corresponding center of the rack 12. The extension direction of the arc groove 19 is consistent with the moving trajectory of the slider 20. The slider 20 can be embedded in the arc groove 19 and can move back and forth.

[0042] During implementation, the rack 12 and the gear 11 can be set below the plane where the second chassis 10 is located. Specifically, the slider 20 can be extended to the bottom of the second chassis 10, so that the rack 12 is fixedly connected to the slider 20. At the same time, in order to facilitate the application of force to the gear 11 to rotate the gear 11, the axle of the gear 11 can be passed through the top of the second chassis 10, and a first handle 25 is provided on the axle of the gear 11. The first handle 25 is rotatably connected to the upper end of the axle of the gear 11, and the rotation axis is set in the horizontal direction. When rotating the gear 11, the first handle 25 is turned upward to facilitate the application of force. After adjusting the relative positions of the first chassis 9 and the second chassis 10, the first handle 25 is turned downward to make it close to the second chassis 10.

[0043] In practice, the adjustment mechanism further includes a locking assembly that can limit the rotation of the gear 11. After the relative position between the first chassis 9 and the second chassis 10 is adjusted, the rotation of the gear 11 is limited by the locking assembly, thereby locking the relative position of the first chassis 9 and the second chassis 10. The locking assembly specifically includes a second handle 26 rotatably connected to the upper end of the axle of the gear 11 at the first end and a cam relatively fixedly arranged at the first end of the second handle 26, the cam being located on a side of the second handle 26 close to the second chassis 10, and the cam and the second handle 26 being fixedly connected to form an integrated structure. When the second handle 26 is close to the second chassis 10, the hinge point between the second handle 26 and the axle of the gear 11 is at the lowest point, and the gap between the gear 11 and the cam is greater than the thickness of the second chassis 10, so that the gear 11 can rotate smoothly under the drive of the first handle 25; when the second handle 26 is rotated upward to an inclined state or a vertical state, the cam drives the hinge point between the second handle 26 and the gear 11 to move upward, thereby driving the gear 11 to move upward, so that the gear 11 and the cam are clamped together on the upper and lower surfaces of the second chassis 10, as shown in FIG. Figure 5 As shown, the rotation of the gear 11 is restricted, thereby achieving the locking of the relative position between the gear 11 and the rack 12, that is, the relative position between the first chassis 9 and the second chassis 10 is locked.

[0044] When the locking assembly is in the locked state, the second handle 26 is in an inclined state or a vertical state, and the host 1 cannot be adjusted to a position where its lower surface is parallel to the first chassis 9. When the locking assembly is unlocked, the second handle 26 is close to the second chassis 10, allowing the host 1 to be adjusted to a position where its lower surface is parallel to the first chassis 9. Therefore, when the satellite communication portable station is stored, in order to adjust the host 1 to a position where its lower surface is parallel to the first chassis 9, the second handle 26 needs to be rotated to be close to the second chassis 10, and the gear 11 can be rotated. During transportation, due to inertia, the force generated by the relative movement between the host 1, the adjustment bracket 4 and the base 3 will act on the gear 11 and the rack 12. When the force is too large, if the gear 11 and the rack 12 cannot be transmitted, the gear 11 and the rack 12 will be damaged. Therefore, when the locking assembly is in the unlocked state, the gear 11 can be protected, which is conducive to extending the service life of the gear 11.

[0045] In this embodiment, a support foot 13 is provided at the second end of the first chassis 9. The support foot 13 is provided in the vertical direction, with the lower end fixedly connected to the first chassis 9 and the upper end rotatably connected to the second end of the host 1. The provision of the support foot 13 increases the distance between the second end of the host 1 and the ground, which can avoid the problem of the parabolic antenna 2 touching the ground during polarization adjustment.

[0046] In the preferred solution of this embodiment, the parabolic antenna 2 is configured to have five detachable parts, as shown in FIG. Figure 6, specifically including a first array face 14 and four second array faces 15. The first array face 14 is fixedly connected to the host 1, and the four second array faces 15 are all detachably connected to the first array face 14. Specifically, this can be achieved through a quick-lock buckle. The quick-lock buckle is a mature existing technology. The structure and working principle of the quick-lock buckle will not be described here. The contour of the opposite end of the vertex end of the parabola antenna 2 is a circle. The projection of the first array face 14 on the plane where the circle is located coincides with the inscribed rectangle of the circle. The other parts of the parabola antenna 2 except the first array face 14 are the second array faces 15. The four second array faces 15 are distributed along the circumference of the first array face 14. The first array face 14 is an arc surface with a certain amount of accommodation space above it. When the satellite communication portable station is folded and stored, the four second array faces 15 can be removed and placed on the first array face 14, which takes up little space.

[0047] The parabola antenna 2 also includes a feed rod 21, a mounting seat is provided at the vertex of the parabola antenna 2, one end of the feed rod 21 is detachably connected to the mounting seat on the parabola antenna 2, and when the satellite communication portable station is folded and stored, the feed rod 21 can be removed from the mounting seat of the parabola antenna 2 and placed in the first array surface 14. The detachable connection between the feed rod 21 and the mounting seat of the parabola antenna 2 can be achieved by a snap-on structure, as shown in FIG. Figure 7 As shown, a hook 22 capable of elastic deformation is provided on the first array surface 14 , and a clamping ring 23 is provided on the feed rod 21 . When the feed rod 21 is plugged into the mounting seat of the parabolic antenna 2 , the hook 22 is clamped in the clamping ring 23 .

[0048] In a preferred embodiment, a posture sensor capable of detecting the position state of the host 1 is also provided in the host 1, and the model may be Saber C3. The posture sensor is in communication connection with the control display module, and the actual azimuth, pitch angle, and polarization angle information of the host 1 can be displayed on the display panel 17 of the host 1 in real time by using the posture sensor. The theoretical values ​​of the azimuth, pitch angle, and polarization angle corresponding to the current position of the satellite communication portable station are preset in the host 1, and the above theoretical values ​​are also displayed on the display panel 17 of the host 1, prompting the user to adjust the angle of the parabolic antenna 2 to the theoretical value, which greatly improves the efficiency and accuracy of satellite alignment.

[0049] When the satellite communication portable station is in a folded storage state, there is a certain storage space below the parabolic antenna 2 at the positions on both sides of the main unit 1. During implementation, two storage boxes 16 can be set at the first end of the base 3. The distance between the two storage boxes 16 is greater than the size of the main unit 1. The storage boxes 16 can be used to place batteries and circuit boards related to the power supply.

[0050] During implementation, a groove 24 for accommodating the adjustment bracket 4 is provided on the first chassis 9. When in the folded state, the adjustment bracket 4 is located in the groove 24, so that the satellite communication portable station is folded to a minimum space occupied. The lower surface of the host 1 is supported on the upper surface of the first chassis 9, which increases the stability of the folded state.

[0051] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
