Description
Technical Field
[0001] This invention relates to the field of BeiDou satellite signal receiving technology, and in particular to a BeiDou satellite signal receiving device that optimizes signal reception strength. Background Technology
[0002] The BeiDou Navigation Satellite System is a global satellite navigation system independently developed by my country, with wide applications in transportation, marine fisheries, surveying and mapping, and emergency rescue. As the terminal equipment of the BeiDou navigation system, the signal strength of the BeiDou satellite signal receiving device directly affects positioning accuracy and navigation performance.
[0003] Existing BeiDou satellite signal receivers are typically fixed in one direction when receiving signals. When the signal strength is weak, the angle of the receiver cannot be adjusted to enhance the signal reception. To address this issue, utility model patent CN212723372U discloses a BeiDou satellite signal receiver with adjustable angle. This device includes a support base, mounting platform, mounting cavity, fixing screw, servo motor, movable sleeve, support rod, slide groove, support adjustment platform, signal receiver, fixed shaft seat, and adjustment linkage. Its working principle is as follows: the servo motor drives the fixing screw to rotate, causing the movable sleeve to move horizontally left and right. The movable sleeve, through the support rod, drives the support adjustment platform to move. The support adjustment platform rotates through the push and pull of the adjustment linkage, thereby rotating the signal receiver to achieve angle adjustment.
[0004] However, the aforementioned existing technology still suffers from a single adjustment dimension. This device can only achieve angle adjustment in a single direction, failing to provide multi-dimensional, omnidirectional pointing adjustment, and thus cannot meet the signal reception requirements of satellites at different azimuth and elevation angles. Therefore, we provide a BeiDou satellite signal receiving device with optimized signal reception strength to improve upon this. Summary of the Invention
[0005] To overcome the above shortcomings, this invention provides a BeiDou satellite signal receiving device that optimizes signal reception strength, aiming to improve the problem that existing technologies cannot achieve multi-dimensional and all-round pointing adjustment and are difficult to adapt to the signal reception requirements of satellites at different azimuth and elevation angles.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a BeiDou satellite signal receiving device for optimizing signal reception strength, comprising a mounting base, a protective cover fixedly disposed on the top of the mounting base, the protective cover being spherical, a rotating ring disposed inside the protective cover, a transmission assembly disposed between the rotating ring and the mounting base, a guide ring fixedly disposed inside the rotating ring, an equipment mounting platform disposed inside the guide ring, a BeiDou signal receiving device mounted on the equipment mounting platform, a rotating assembly disposed between the equipment mounting platform and the guide ring, and the protective cover being made of a wave-transparent material;
[0007] The transmission assembly includes an annular rack disposed on the outside of the rotating ring, a transverse worm gear disposed inside the mounting base, a first servo motor disposed at one end of the transverse worm gear, and the annular rack meshing with the transverse worm gear.
[0008] As a further description of the above technical solution:
[0009] The inner wall of the protective cover is provided with a slot to accommodate the rotation of the annular rack. The two ends of the inner wall of the slot and the two ends of the inner wall of the rotating ring are provided with a matching groove structure to limit the axial displacement of the rotating ring and ensure its smooth rotation.
[0010] As a further description of the above technical solution:
[0011] The rotating assembly includes an annular groove formed inside the guide ring, and annular teeth are provided in the annular groove. A second drive motor is provided at both ends of the equipment mounting platform. A transmission gear is provided at one end of the second drive motor. The transmission gear extends into the annular groove and meshes with the annular teeth. The second drive motor is fixedly connected to the equipment mounting platform.
[0012] As a further description of the above technical solution:
[0013] The inner wall of the annular groove is provided with a plurality of locking holes. An electric telescopic rod is provided on the equipment mounting platform on one side of the second drive motor. The driving end of the electric telescopic rod can extend into the locking holes to lock the equipment mounting platform at the current angle position.
[0014] As a further description of the above technical solution:
[0015] An annular guide groove is provided below the plurality of locking holes, and a guide rod is provided at the end of the transmission gear away from the second drive motor. The guide rod extends into the annular guide groove and is rotatably connected to the annular guide groove.
[0016] As a further description of the above technical solution:
[0017] The annular guide groove and the guide rod are T-shaped structures that cooperate with each other. The T-shaped head of the guide rod is embedded in the T-shaped groove of the annular guide groove, which is used to limit the axial displacement of the equipment mounting platform and guide its rotational movement.
[0018] As a further description of the above technical solution:
[0019] The rotation is around the first axis, and the equipment mounting platform is around the second axis.
[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are as follows:
[0021] 1. In this invention, by rotating the device around the first axis and swinging the device mounting platform around the second axis, dual-axis angle adjustment of the BeiDou signal receiving device in two orthogonal directions is achieved. The rotation ring and the rotation axis of the device mounting platform cooperate with each other, allowing the signal receiving device to point in multiple directions in three-dimensional space, adapting to the signal receiving needs of satellites at different azimuth and elevation angles, and significantly improving the flexibility and adaptability of signal reception.
[0022] 2. In this invention, a spherical protective cover is used to completely enclose the rotating ring, guide ring, equipment mounting platform, and Beidou signal receiving equipment. The protective cover is made of wave-transparent material, which ensures that the Beidou satellite signal can penetrate without damage while providing effective physical protection for the internal precision components. This avoids the erosion and damage to the equipment caused by harsh environments such as wind, sand, rain, snow, and high temperature, and extends the service life of the equipment.

[0031] 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.
[0032] Example 1
[0033] like Figures 1 to 6 As shown, this embodiment provides a BeiDou satellite signal receiving device with optimized signal reception strength. The protective cover 2 is spherical and is fixedly installed on the top of the mounting base 1. The protective cover 2 is made of a wave-transparent material to ensure that the BeiDou satellite signal can penetrate without damage, and completely encloses the internal components inside it. While ensuring the BeiDou satellite signal can penetrate without damage, it also provides effective physical protection for the internal components.
[0034] The protective cover 2 has a rotating ring 3 inside. The inner wall of the protective cover 2 has a groove 21, which is an annular groove structure that extends circumferentially along the inner wall of the protective cover 2. The rotating ring 3 is embedded in the groove 21, and the width of the groove 21 is adapted to the thickness of the rotating ring 3, so that the rotating ring 3 can rotate freely within the groove 21.
[0035] The inner walls of the slot 21 and the inner walls of the rotating ring 3 are provided with interlocking groove structures 22 to limit the axial displacement of the rotating ring 3 and ensure its smooth rotation. At the same time, the mating surface between the annular protrusion and the annular groove is a smooth contact surface. When the rotating ring 3 rotates, the annular protrusion slides along the annular groove, which provides guidance for the rotational movement of the rotating ring 3 and ensures its smooth rotation.
[0036] A transmission assembly 4 is provided between the rotating ring 3 and the mounting base 1. The transmission assembly 4 is used to transmit the power of the first servo motor 43 to the rotating ring 3, driving the rotating ring 3 to rotate around the first axis.
[0037] Specifically, the transmission assembly 4 includes a ring rack 41, a transverse worm gear 42, and a first servo motor 43. The ring rack 41 is disposed on the outer side of the rotating ring 3. The ring rack 41 has a ring structure and is fixedly installed on the outer wall surface of the rotating ring 3, and is coaxially arranged with the rotating ring 3. The teeth of the ring rack 41 face radially outward from the rotating ring 3.
[0038] A transverse worm gear 42 is internally disposed within the mounting base 1. The transverse worm gear 42 is horizontally positioned within the internal cavity of the mounting base 1. The axial direction of the transverse worm gear 42 is perpendicular to the first axis. The threaded portion of the transverse worm gear 42 extends into the interior of the protective cover 2, corresponding to the position of the annular rack 41. The annular rack 41 meshes with the transverse worm gear 42, and a first servo motor 43 is disposed at one end of the transverse worm gear 42. The first servo motor 43 is fixedly mounted inside the mounting base 1, and its output shaft is fixedly connected to one end of the transverse worm gear 42. The output shaft of the first servo motor 43 is coaxially arranged with the transverse worm gear 42.
[0039] The power transmission path in this embodiment is: first servo motor 43 → transverse worm gear 42 → annular rack 41 → rotating ring 3.
[0040] Through the above connection structure, when the first servo motor 43 is started, the output shaft of the first servo motor 43 drives the transverse worm gear 42 to rotate. The transverse worm gear 42 drives the ring rack 41 to rotate through the meshing transmission between its threaded part and the ring rack 41. The ring rack 41 drives the rotating ring 3 to rotate around the first axis in the slot 21.
[0041] Because the transverse worm gear 42 and the ring rack 41 are driven by a worm gear meshing transmission, it has advantages such as a large transmission ratio, compact structure, smooth transmission, and good self-locking performance, enabling high-precision angle adjustment. At the same time, the self-locking characteristic of the worm gear transmission allows the rotating ring 3 to maintain its current angular position when there is no power input, making it less prone to deflection due to external forces.
[0042] Meanwhile, the interlocking groove structure 22 between the slot 21 and the rotating ring 3 restricts the axial displacement of the rotating ring 3, preventing axial movement of the rotating ring 3 during rotation and ensuring the smoothness of the rotational motion and the accuracy of the angle adjustment.
[0043] Example 2
[0044] like Figure 3 and Figure 5As shown, this embodiment provides a BeiDou satellite signal receiving device with optimized signal reception strength. Based on the first embodiment, the rotational connection structure and angle locking mechanism between the equipment mounting platform 6 and the guide ring 5 are further optimized.
[0045] A guide ring 5 is fixedly installed inside the rotating ring 3. The guide ring 5 has an annular structure, and its outer wall is fixedly connected to the inner wall of the rotating ring 3. The guide ring 5 is coaxial with the rotating ring 3. The guide ring 5 rotates together with the rotating ring 3 around the first axis. An equipment mounting platform 6 is installed inside the guide ring 5. The equipment mounting platform 6 has a flat structure and is used to install the Beidou signal receiving device 7. The Beidou signal receiving device 7 is installed on the equipment mounting platform 6. A rotating assembly 8 is provided between the equipment mounting platform 6 and the guide ring 5 to drive the equipment mounting platform 6 to swing around the second axis.
[0046] The rotating assembly 8 includes an annular groove 51, an annular toothed pattern 52, a second drive motor 61, and a transmission gear 62. The annular groove 51 is located inside the guide ring 5. The annular groove 51 is an annular recess structure that extends circumferentially along the inner wall of the guide ring 5. The opening of the annular groove 51 faces radially inward towards the guide ring 5. An annular toothed pattern 52 is provided within the annular groove 51. The annular toothed pattern 52 is an annular rack structure and is fixedly mounted on the inner wall surface of the annular groove 51. The teeth of the annular toothed pattern 52 face inward towards the annular groove 51.
[0047] A second drive motor 61 is installed at both ends of the equipment mounting platform 6. The housing of the second drive motor 61 is fixed to the ends of the equipment mounting platform 6 by screws or welding and moves with the equipment mounting platform 6. The output shaft of the second drive motor 61 extends along the width direction of the equipment mounting platform 6, and a transmission gear 62 is installed at one end of the second drive motor 61. The transmission gear 62 is fixedly installed on the output shaft of the second drive motor 61. The transmission gear 62 extends into the annular groove 51 and meshes with the annular teeth 52.
[0048] The inner wall of the annular groove 51 is provided with a plurality of locking holes 53. The plurality of locking holes 53 are arranged at intervals along the circumference of the annular groove 51, and each locking hole 53 corresponds to a different angular position. The opening direction of the locking holes 53 faces the interior of the annular groove 51.
[0049] An electric telescopic rod 63 is installed on one side of the second drive motor 61 on the equipment mounting platform 6. The electric telescopic rod 63 is fixedly installed at the end of the equipment mounting platform 6 and moves with the equipment mounting platform 6. The drive end of the electric telescopic rod 63 extends along the width direction of the equipment mounting platform 6. The drive end of the electric telescopic rod 63 corresponds to the position of the locking hole 53, and the drive end of the electric telescopic rod 63 can extend into the locking hole 53 to lock the equipment mounting platform 6 at the current angle position.
[0050] An annular guide groove 54 is provided below several locking holes 53. The annular guide groove 54 is an annular groove structure that extends circumferentially along the inner wall of the annular groove 51. The annular guide groove 54 is located below the locking holes 53 and is coaxially arranged with the annular groove 51.
[0051] A guide rod 64 is provided at the end of the transmission gear 62 away from the second drive motor 61. The guide rod 64 is a rod-shaped structure, with one end fixedly connected to the transmission gear 62 and the other end extending along the axis of the transmission gear 62. The guide rod 64 extends into the annular guide groove 54 and is rotatably connected to the annular guide groove 54. The annular guide groove 54 and the guide rod 64 are a mutually cooperating T-shaped structure, specifically, the T-shaped head of the guide rod 64 is embedded in the T-shaped groove of the annular guide groove 54, which is used to limit the axial displacement of the equipment mounting platform 6 and guide its rotational movement.
[0052] The power transmission path in this embodiment is as follows: second drive motor 61 → transmission gear 62 → annular tooth pattern 52 → guide ring 5 → relative motion is generated on the equipment mounting platform 6.
[0053] The locking control path in this embodiment is as follows: electric telescopic rod 63 → drive end extends → inserted into locking hole 53 → equipment mounting platform 6 is locked.
[0054] The guiding and mating path is as follows: the T-shaped head of the guide rod 64 → slides along the annular guide groove 54 → restricts axial displacement → guides rotational motion.
[0055] Through the aforementioned connection structure, when the second drive motor 61 starts, its output shaft drives the transmission gear 62 to rotate. The transmission gear 62, through the meshing of its toothed portion with the annular toothed pattern 52, rolls along the annular toothed pattern 52. Since the annular toothed pattern 52 is fixedly mounted on the guide ring 5, the rolling motion of the transmission gear 62 is converted into the oscillating motion of the equipment mounting platform 6 around the second axis. That is, the second drive motor 61 and the transmission gear 62 move relative to the fixed annular toothed pattern 52, thereby driving the equipment mounting platform 6 to oscillate around the second axis.
[0056] Once the equipment mounting platform 6 swings around the second axis to the target angle, the electric telescopic rod 63 is activated. The drive end of the electric telescopic rod 63 extends and enters the locking hole 53 at the corresponding position on the inner wall of the annular groove 51. Through the engagement of the drive end and the locking hole 53, the equipment mounting platform 6 is locked at the current angle position. This locking mechanism effectively prevents the Beidou signal receiving equipment 7 from angular displacement when subjected to external vibration or wind, ensuring the continuous stability of signal reception.
[0057] Simultaneously, as the equipment mounting platform 6 swings around the second axis, the T-shaped head of the guide rod 64 slides along the T-groove of the annular guide groove 54. Because the T-shaped head is constrained within the T-groove, the axial displacement of the equipment mounting platform 6 is limited, preventing axial movement during the swing. At the same time, the annular guide groove 54 guides the sliding of the guide rod 64, ensuring that the equipment mounting platform 6 swings smoothly along a preset trajectory, improving the accuracy and stability of angle adjustment.
[0058] Furthermore, the rotational motion of the rotating ring 3 around the first axis and the swinging motion of the equipment mounting platform 6 around the second axis are independent of each other and do not interfere with each other. Through the combination of the two, the Beidou signal receiving device 7 can point in multiple directions in three-dimensional space, realizing multi-dimensional angle adjustment.
[0059] The implementation principle of this application's embodiment of a BeiDou satellite signal receiving device for optimizing signal reception strength is as follows: The BeiDou signal receiving device 7 receives signals from BeiDou satellites. Because the position of BeiDou satellites in the sky constantly changes with time and location, when the pointing direction of the BeiDou signal receiving device 7 deviates from the direction of the satellite, the received signal strength will be significantly weakened, affecting positioning accuracy and navigation performance. When the signal strength received by the BeiDou signal receiving device 7 is lower than a preset threshold, an angle adjustment mechanism is activated.
[0060] When it is necessary to adjust the angle of the Beidou signal receiving device 7 in the first direction, the first servo motor 43 is activated. The output shaft of the first servo motor 43 rotates, driving the transverse worm gear 42, which is fixedly connected to it, to rotate synchronously. The threaded part of the transverse worm gear 42 meshes with the annular rack 41 on the outer side of the rotating ring 3, driving the annular rack 41 to rotate around the first axis. The annular rack 41 is fixedly mounted on the outer wall of the rotating ring 3, driving the rotating ring 3 to rotate synchronously around the first axis. The rotating ring 3 drives the equipment mounting platform 6 and the Beidou signal receiving device 7 mounted on it to rotate synchronously around the first axis through the guide ring 5, thereby realizing the precise adjustment of the angle of the Beidou signal receiving device 7 in the first direction.
[0061] When it is necessary to adjust the angle of the Beidou signal receiving device 7 in the second direction, the second drive motor 61 is activated. The output shaft of the second drive motor 61 rotates, driving the transmission gear 62, which is fixedly connected to it, to rotate synchronously. The transmission gear 62 meshes with the annular teeth 52 provided in the annular groove 51 on the inner side of the guide ring 5. Since the annular teeth 52 is fixed, the transmission gear 62 rolls along the annular teeth 52, driving the second drive motor 61 and the equipment mounting platform 6, which is fixedly connected to the second drive motor 61, to swing around the second axis. The Beidou signal receiving device 7 swings synchronously around the second axis with the equipment mounting platform 6, thereby achieving precise adjustment of the angle of the Beidou signal receiving device 7 in the second direction.
[0062] During the aforementioned adjustment process, the rotational motion of the rotating ring 3 around the first axis and the oscillating motion of the equipment mounting platform 6 around the second axis are independent and do not interfere with each other. By rotating the rotating ring 3 around the first axis, the angle of the BeiDou signal receiving device 7 in the first direction is adjusted; by oscillating the equipment mounting platform 6 around the second axis, the angle of the BeiDou signal receiving device 7 in the second direction is adjusted. The movements in the two directions cooperate and work together, allowing the BeiDou signal receiving device 7 to point in any direction in three-dimensional space, thereby aligning with the BeiDou satellite at the optimal angle.
[0063] Once the BeiDou signal receiving device 7 is adjusted to the target angle with optimal signal strength, the electric telescopic rod 63 is activated. The drive end of the electric telescopic rod 63 extends into the locking hole 53 at the corresponding position on the inner wall of the annular groove 51. Through the engagement of the drive end and the locking hole 53, the device mounting platform 6 is locked at the current angle position, preventing it from shifting in angle under external vibration or wind force. This ensures that the BeiDou signal receiving device 7 continues to receive satellite signals at the optimal angle, thereby effectively improving the reception strength of BeiDou satellite signals.
