Description

Technical Field

[0001] The invention relates to the technical field of satellite communication antennas, in particular to a terminal antenna used for Tiantong satellite communication. Background Art

[0002] Tiantong Satellite is a communication satellite system independently developed by China, mainly used to provide satellite communication services covering the whole country, especially in remote areas and areas lacking ground communication infrastructure. The system consists of a series of geostationary orbit (GEO) satellites, designed to achieve all-round, all-weather communication services, including telephone, data transmission and broadcasting. The characteristics of Tiantong Satellite are its high bandwidth and low latency, which can support simultaneous communication of large-scale users. Tiantong Satellite mainly consists of two parts: the satellite itself and the ground system. The satellite adopts advanced satellite technology and has multi-band communication capabilities, supporting C-band and Ku-band signal transmission, which enables it to adapt to different communication needs and environments.

[0003] In order to achieve efficient communication, Tiantong satellite is equipped with many antenna systems. Its antenna design usually includes a high-power main antenna and multiple sub-antennas, which can achieve wide signal coverage and efficient signal transmission. The main antenna is usually a high-gain parabolic antenna, which can concentrate signals and improve communication quality. The sub-antenna is used for different functions, such as covering specific areas or supporting mobile terminal communications.

[0004] In Tiantong satellite communications, the antenna is an omnidirectional communication antenna, which is precisely aligned with the satellite in three-dimensional space to ensure that the antenna can maintain stable signal reception under the changing satellite orbit. In outdoor environments, the antenna may be affected by wind, causing its attitude to shift. The antenna support structure needs to have sufficient rigidity and stability to withstand wind and other external interference, while ensuring anti-overturning ability in the working state. During the movement, the antenna system may generate vibration and noise, affecting the signal quality. Vibration isolation measures need to be considered in the design to reduce the impact of these factors on signal reception.

[0005] The Chinese patent with the existing authorization announcement number CN106785387B discloses a transceiver antenna for a satellite communication handheld terminal, including a dielectric body, an antenna radiator and a feeding module. The antenna radiator adopts a spiral structure and is composed of four groups of spiral arms with a phase difference of 90 degrees. The dielectric body adopts a columnar structure. The antenna radiator is laser engraved on the outer surface of the dielectric body. The tops of the four groups of spiral arms are short-circuited and connected to each other. The four groups of spiral arms are arranged at equal intervals. Each group of spiral arms includes a high-frequency spiral arm and a low-frequency spiral arm connected at the bottom. The feeding module is arranged inside the lower end of the dielectric body. The feeding module is respectively connected to the four groups of spiral arms. The surface of the dielectric body is sprayed with a paint layer, and the paint layer covers the antenna radiator. The present invention relates to the field of mobile communications. Compared with the traditional FPC antenna, the transceiver antenna directly laser engraves the antenna radiator on the surface of the dielectric body, which can more effectively utilize space and achieve miniaturization.

[0006] However, since the above-mentioned transceiver antenna has no auxiliary fixing device, the signal transmission stability is poor, and the length of other terminal antennas in the prior art needs to be manually adjusted. The longer the length, the greater the antenna amplitude and shaking amplitude, and the greater the vibration impact, affecting the signal transmission stability. At the same time, the heat dissipation effect of the above-mentioned terminal antenna is poor during use, resulting in low terminal working efficiency. Summary of the invention

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1 Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, provides a terminal antenna for Tiantong satellite communication, including a shell 100, a signal transceiver mechanism, a telescopic mechanism and a control module. By setting the satellite receiving signal strength value, the signal antenna 200 is controlled to automatically extend and retract, thereby realizing automatic adjustment of the signal receiving area of ​​the signal antenna 200, avoiding complex manual adjustment steps, optimizing the operation process, and at the same time, auxiliary cooling of the terminal interior can be performed by hydraulic oil to increase the terminal working time.

[0034] Specifically, it includes: a housing 100, wherein a terminal is arranged inside the housing 100, and the terminal is used to communicate with the Tiantong satellite; The signal transceiver mechanism includes a housing 100 with at least one signal antenna 200 disposed on the end surface thereof, the signal antenna 200 being used to receive the Tiantong satellite signal and transmit it to the terminal; The telescopic mechanism includes a telescopic column 300 disposed on the housing 100. A limit frame 301 is also nested on the housing 100. The limit frame 301 is used to fix two adjacent signal antennas 200. The telescopic column 300 is extended and retracted by hydraulic oil. The telescopic column 300 drives the signal antenna 200 and the limit frame 301 to synchronously telescope. The control module includes an oil pump 400 disposed in the housing 100. The oil pump 400 is used to drive the hydraulic oil to flow in both directions. The oil pump 400 controls the switch and the flow direction of the hydraulic oil by the signal strength value received by the signal antenna 200. When the hydraulic oil in the oil pump 400 flows downward, the telescopic column 300 moves upward and drives the signal antenna 200 to move upward to increase the receiving area, until the signal strength value received by the signal antenna 200 increases to a set threshold value, and then the oil pump 400 is controlled to be turned off.

[0035] Among them, the terminal is a handheld satellite communication terminal for communicating with the Tiantong satellite. In this embodiment, the number of signal antennas 200 is two, and the telescopic column 300 is sealed to the shell 100 to prevent water vapor and dust from entering when telescoping in an outdoor environment.

[0036] Furthermore, the receiving signal strength value of the terminal can be set. When the current signal is less than the set value, the oil pump 400 pumps the hydraulic oil downward. When the signal values ​​are the same, the oil pump 400 is closed and the connecting pipe 1003 is sealed. When the signal value is less than the set value, the oil pump 400 pumps the hydraulic oil upward.

[0037] Preferably, a first sealed cavity 1001 and a second sealed cavity 1002 are respectively provided inside the housing 100 , a connecting pipe 1003 is provided between the first sealed cavity 1001 and the second sealed cavity 1002 , and an oil pump 400 is provided in the middle of the connecting pipe 1003 .

[0038] More preferably, the first sealed cavity 1001 and the second sealed cavity 1002 are engineering plastic cavities, the first sealed cavity 1001 is located below the second sealed cavity 1002, and is filled with hydraulic oil. After the hydraulic oil pressure exceeds the safety threshold, the engineering plastic cavity can undergo a small elastic deformation for buffering.

[0039] The telescopic column 300 includes a first sleeve 1004 slidably mounted on the inner wall, the inner wall of the first sleeve 1004 is slidably mounted on the second sleeve 1005 , and the first sleeve 1004 , the second sleeve 1005 and the lower end surface of the telescopic column 300 are simultaneously provided with a step sleeve 1006 .

[0040] More preferably, the inner wall of the telescopic column 300, the inner wall of the first sleeve 1004 and the lower end surface of the second sleeve 1005 together form a first cavity 1007, the inner wall of the telescopic column 300 and the outer wall of the first sleeve 1004 form a second cavity 1008, and the outer walls of the first sleeve 1004 and the second sleeve 1005 form a third cavity 1009.

[0041] Among them, the telescopic column 300 and the first sleeve 1004 are both hollow sleeve shapes, the step sleeve 1006 is made of wear-resistant plastic material, and is used for sealing to prevent leakage of hydraulic oil. Each cavity is isolated from each other by the step sleeve 1006. The hydraulic oil absorbs heat inside the shell 100 during the flow process. The telescopic column 300 is made of aluminum alloy. After being transmitted to the telescopic column 300, the heat is dissipated into the air, achieving a circulating heat dissipation effect.

[0042] Furthermore, a first flow channel 1011 is opened on the step sleeve 1006 of the telescopic column 300 , and the first flow channel 1011 is connected to the first cavity 1007 . A second flow channel 1012 is opened on the inner wall of the telescopic column 300 and the first sleeve 1004 , and the second flow channel 1012 is connected to the second cavity 1008 and the third cavity 1009 .

[0043] Among them, a first oil pipe 1013 is provided at one end of the first flow channel 1011 extending to the outside of the telescopic column 300, and a second oil pipe 1014 is provided at one end of the second flow channel 1012 extending to the outside of the telescopic column 300. The first oil pipe 1013 and the second oil pipe 1014 are respectively connected to the first sealed cavity 1001 and the second sealed cavity 1002.

[0044] In summary, in the initial state, the satellite communication strength is adjusted to the working value, and the signal antenna 200 is retracted in the shell 100. When the signal strength value of the terminal receiving the signal antenna 200 is low, the control oil pump 400 is started and the hydraulic oil in the second sealed cavity 1002 is pumped downward to the first sealed cavity 1001. The pressure in the first sealed cavity 1001 increases, pushing the excess hydraulic oil along the first oil pipe 1013 to flow to the first cavity 1007 and pushing the lower end surface of the second sleeve 1005 to move upward. At the same time, the hydraulic oil in the third cavity 1009 flows out along the second oil pipe 1014 and enters the second sealed cavity 1002, and is finally pumped to the first sealed cavity 1001 by the oil pump 400, thereby completing the internal and external circulation of the hydraulic oil, bringing the heat in the shell 100 out through the first oil pipe 1013 and the hydraulic oil entering through the second oil pipe 1014 to dissipate the heat of the shell 100.

[0045] At the same time, as the lower end surface of the second sleeve 1005 is pushed upward, it eventually drives the first sleeve 1004 to slide upward, thereby extending the telescopic column 300, thereby pushing the signal antenna 200 upward, increasing the height and receiving area, and continuously improving the satellite communication strength until the strength reaches the set threshold. At this time, the terminal controls the oil pump 400 to stop and close the connecting pipe 1003, thereby fixing the signal antenna 200 at the current height; when it needs to be retracted, the satellite communication strength is adjusted to a low position. At this time, the oil pump 400 pumps hydraulic oil upward until the signal antenna 200 is retracted to the inside of the shell 100, and the signal strength value is reduced to a low position, thereby keeping the telescopic column 300 stationary.

[0046] Example 2 Reference Figure 1 to Figure 8 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that after the signal antenna 200 is extended into place, it is locked by a limit frame 301 to achieve auxiliary positioning. At the same time, it is adaptable to various diameter sizes of the signal antenna 200 and has a wide range of application scenarios.

[0047] Specifically, in this embodiment, a slide bar 2001 is slidably provided on the limit frame 301, and rotating wheels 2002 are provided on both end surfaces of the slide bar 2001. A limit arm 2003 is also rotatably provided on the limit frame 301, and rotating wheels 2002 are rotatably provided on both end surfaces of the limit arm 2003.

[0048] The slide bar 2001 slides on the limit frame 301 along the radial direction of the signal antenna 200 , the limit arm 2003 is an obtuse-angled broken line rod and rotates along the middle position, and a fixed anti-slip rubber layer is provided on the surface of the rotating wheel 2002 close to the signal antenna 200 .

[0049] Among them, the limiting arms 2003 are symmetrically arranged, and the rotating wheels 2002 on the two limiting arms 2003 and the rotating wheels 2002 on the sliding rod 2001 are always located on the same circle edge, and the circle is coaxially arranged with the signal antenna 200, so that the signal antenna 200 is clamped by three rotating wheels 2002.

[0050] More preferably, a triangular block 2004 is provided on the sliding rod 2001 , and the limiting arm 2003 is slidably fitted on the outer wall of the triangular block 2004 away from the rotating wheel 2002 on one end of the signal antenna 200 .

[0051] Furthermore, the triangle block 2004 is a right triangle and is symmetrically arranged about the slide bar 2001 . The rotating wheel 2002 is rotatably arranged on the hypotenuse of the triangle block 2004 . The right-angled side of the triangle block 2004 is arranged parallel to the slide bar 2001 , and the other right-angled side is arranged away from the signal antenna 200 .

[0052] There are two sets of limit frames 301 symmetrically arranged, and the two sets of limit frames 301 are rotatably provided with a close-fitting column 2005 . The upper end surface of the close-fitting column 2005 is provided with a turntable 2006 , and the outer wall of the turntable 2006 is provided with an inclined surface 2007 and a right-angle surface 2008 .

[0053] More preferably, one end of the slide bar 2001 is slidably fitted to the outer wall of the turntable 2006 through the rotating wheel 2002. When the rotating wheel 2002 rotates along the inclined surface 2007, the slide bar 2001 is driven to slide outward as the diameter of the inclined surface 2007 increases.

[0054] Among them, the limit frame 301 and the close column 2005 move up and down as a whole following the telescopic column 300, and the setting position of the telescopic column 300 is lower than the setting position of the signal antenna 200, so that the limit frame 301 is always located at the center position of the signal antenna 200. At the same time, in this embodiment, the close column 2005 and the limit frame 301 are screwed together through threads, so that they can rotate relative to each other.

[0055] In summary, during use, when the two signal antennas 200 are driven by the telescopic column 300 to move outward to reach the set height, the limit frame 301 and the close column 2005 move up synchronously with the signal antenna 200, and the limit frame 301 is always located in the center position of the signal antenna 200. At this time, the close column 2005 is rotated to drive the turntable 2006 to rotate, so that when the rotating wheel 2002 rotates along the inclined surface 2007, the sliding rod 2001 is driven to slide outward as the diameter of the inclined surface 2007 increases.

[0056] At the same time, the rotating wheel 2002 on the triangular block 2004 rolls along the hypotenuse, so that the limiting arm 2003 flips inward and clamps, and the three rotating wheels 2002 approach the center of the circle synchronously on the same circumference until they are clamped and locked with the outer wall of the signal antenna 200. Since the diameters of the extended telescopic column 300 are different when the signal antenna 200 moves to different heights, the telescopic column 300 of each diameter can be partially clamped by the three rotating wheels 2002. At this time, the two adjacent signal antennas 200 are locked by the limiting frame 301 to prevent the handheld terminal from shaking and oscillating during movement, which affects the reception of Tiantong satellite signals, and the signal antenna 200 is re-positioned to ensure that it is at the optimal signal reception height and improve the stability of signal reception.

[0057] Example 3 Reference Figure 1-Figure 8 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that, when the signal antenna 200 is extended, the limiting frame 301 automatically locks and limits the signal antenna 200 through the rotating cylinder 3004 and the moving ring 3006.

[0058] Specifically, a hollow cylinder 3001 is provided on the end face of the limiting frame 301 , a push plate 3002 is fixedly provided on the telescopic column 300 that drives the limiting frame 301 to move, a linkage rod 3003 is fixedly provided on the push plate 3002 , and the linkage rod 3003 slides through the inside of the hollow cylinder 3001 .

[0059] A rotating cylinder 3004 is movably arranged inside the hollow cylinder 3001 , a spiral groove 3005 is provided on the outer wall of the rotating cylinder 3004 , a moving ring 3006 is slidably arranged between the rotating cylinder 3004 and the inner wall of the hollow cylinder 3001 , and one end of the linkage rod 3003 slides through the moving ring 3006 and is sleeved with a first elastic member 3007 .

[0060] Among them, the first elastic member 3007 is a spring, and both ends of the first elastic member 3007 are respectively connected to the end face of the linkage rod 3003 and the upper end face of the movable ring 3006. When the linkage rod 3003 slides, the first elastic member 3007 is pulled out of the initial state. When the first elastic member 3007 follows the deformation to a certain distance, the tension of the spring overcomes the friction force of the movable ring 3006 and drives it to slide, thereby providing a certain buffer space, so that the telescopic range and telescopic starting point of the limit frame 301 are lower than the signal antenna 200, so that when the signal antenna 200 moves slightly upward, the limit frame 301 does not move.

[0061] Among them, the spiral groove 3005 is a spiral wire groove, the sliding direction of the linkage rod 3003 is parallel to the axial direction of the rotating cylinder 3004, the limit frame 301 is symmetrical and fixedly arranged on the outer wall of the hollow cylinder 3001, and the push plate 3002 and the second sleeve 1005 in the telescopic column 300 move synchronously.

[0062] More preferably, a slider 3008 is provided on the outer wall of the movable ring 3006, and the slider 3008 is slidably provided on the inner wall of the spiral groove 3005. The outer wall of the rotating cylinder 3004 is symmetrically provided with protrusions 3009, and the inner wall of the hollow cylinder 3001 is respectively provided with a first rotating groove 3011, a sliding groove 3012 and a second rotating groove 3013.

[0063] The slider 3008 is slidably disposed in the spiral groove 3005 , and the protrusion 3009 rotates in the first rotating groove 3011 and the second rotating groove 3013 and slides in the sliding groove 3012 .

[0064] Furthermore, the first rotating groove 3011 and the second rotating groove 3013 are arranged in parallel and coaxially, and the sliding groove 3012 is arranged perpendicular to the first rotating groove 3011 and the second rotating groove 3013. The close column 2005 is fixedly connected to the rotating cylinder 3004, so that when the rotating cylinder 3004 and the hollow cylinder 3001 rotate relative to each other, the close column 2005 is driven to rotate alone. A sliding limit block is provided on the hollow cylinder 3001, which is automatically fixed after sliding to the middle position of the signal antenna 200 so that it cannot continue to slide.

[0065] In summary, when in use, as the telescopic column 300 extends upward, the push plate 3002 drives the linkage rod 3003 to move upward and causes the first elastic member 3007 to deform to a certain distance. The tension of the spring overcomes the friction force of the movable ring 3006 and drives it to slide. In the initial stage of the movement of the movable ring 3006, the contact and fit between the slider 3008 and the spiral groove 3005 drives the rotating cylinder 3004 to move. At the same time, the protrusion 3009 slides from the first rotating groove 3011 along the sliding groove 3012 until it slides and fits the second rotating groove 3013 and drives the hollow cylinder 3001 to move upward.

[0066] At this time, as the telescopic column 300 continues to extend, the signal antenna 200 extends too long and needs to be limited and fixed by the limit frame 301. When the limit frame 301 on the hollow cylinder 3001 slides to the midpoint of the signal antenna 200, the hollow cylinder 3001 cannot move further, and thus the rotating cylinder 3004 cannot move further. The slider 3008 on the moving ring 3006 begins to move along the spiral groove 3005, driving the rotating cylinder 3004 to start rotating, and driving the close column 2005 to rotate, thereby finally achieving the limited fixation of the signal antenna 200 and solving the problem of shaking and oscillation caused by the excessive extension length and the unstable received signal strength value caused by it.

[0067] Importantly, it should be noted that the construction and arrangement of the present application shown in a number of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, the element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or otherwise changed, and the nature or number or position of the discrete element can be changed or changed. Therefore, all such modifications are intended to be included in the scope of the present invention. The order or sequence of any process or method steps can be changed or reordered according to alternative embodiments. In the claims, any "device plus function" clause is intended to cover the structure described herein that performs the function, and is not only structurally equivalent but also equivalent structure. Without departing from the scope of the present invention, other replacements, modifications, changes and omissions can be made in the design, operating conditions and arrangement of the exemplary embodiments. Therefore, the invention is not limited to a specific embodiment, but extends to numerous modifications still falling within the scope of the appended claims.

[0068] Additionally, in order to provide a concise description of exemplary embodiments, all features of an actual embodiment may not be described (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those features that are not relevant to implementing the invention).

[0069] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made.
