Abstract
Description
Technical Field
[0001] This utility model relates to the field of generator technology, specifically to an antenna signal generator. Background Technology
[0002] An antenna signal generator is a device used to generate specific antenna signals. It can generate electromagnetic signals of different frequencies, powers, and modulation methods to simulate signal transmission in real-world communication scenarios. It is widely used in antenna testing, wireless communication system development, and radar system debugging, helping engineers verify antenna performance and optimize communication links. Its core functions include signal generation, parameter adjustment, and output control. It features high precision and strong stability, providing crucial testing support for the development and application of wireless communication technology.
[0003] According to a published antenna signal generator (publication number: CN206650656U), it includes: a video signal generator, a local oscillator signal generator, and a frequency converter. The video signal generator and the local oscillator signal generator are connected to the input terminal of the frequency converter, which is a frequency converter used for up-conversion. The video signal generator includes a clock distribution module, a crystal oscillator, a control unit, a digital frequency synthesizer, a phase detection module, and a signal sampling module. It realizes a phased array antenna signal generator based on DDS, which has the characteristics of fast phase shift speed, low loss, small size, and low cost.
[0004] However, the above-mentioned application achieves signal transmission through the cooperation of frequency converter and control unit, but there are also problems such as poor signal generation effect and low signal transmission efficiency. Therefore, an antenna signal generator is proposed. Utility Model Content
[0005] This invention proposes an antenna signal generator that solves the problems of poor signal generation effect and low signal transmission efficiency in related technologies.
[0006] According to one aspect, at least one embodiment of this disclosure provides an antenna signal generator, comprising: a housing, a support foot fixedly connected to the bottom of the housing, a control panel provided on the side of the housing, a switch button provided on the side of the control panel, and a circumferential rotation mechanism provided inside the housing;
[0007] The circumferential rotation mechanism includes a motor, the bottom of which is fixedly connected to the inner side of the housing. A worm gear is fixedly connected to the end of the motor's output shaft. A rotating shaft is rotatably connected to the inner side of the housing. A worm wheel is fixedly connected to the circumferential surface of the rotating shaft. The circumferential surface of the worm gear is threaded onto the circumferential surface of the worm wheel. An external gear is fixedly connected to the circumferential surface of the rotating shaft. An annular slider is slidably connected to the inner side of the housing. An internal gear is fixedly connected to the side of the annular slider. The external gear and the internal gear mesh with each other. A sleeve is fixedly connected to the top of the internal gear.
[0008] For example, in an antenna signal generator provided in at least one embodiment of this disclosure, the following is also included: a groove is provided on the inner side of the housing, and the side of the annular slider is slidably connected inside the groove. The groove provides a precise sliding path for the annular slider, ensuring that the internal gear and the sleeve rotate along a fixed circumferential trajectory and avoiding deviation or shaking.
[0009] The number of support feet is set to several, and they are symmetrical to each other along the vertical central axis of the shell, so as to evenly bear the weight of the shell and internal mechanism, avoid the equipment tilting or the center of gravity shifting, and ensure the stability of operation. The width of the annular slider is equal to the width of the groove, which can prevent the annular slider from swaying left and right in the groove, and ensure that the internal gear and the external gear always maintain the correct meshing position, avoiding transmission errors or jamming.
[0010] The internal gear has spokes on its side, and the number of spokes is set to several and arranged in a circumferential array on the side of the internal gear. This reduces the amount of material used while ensuring strength, lowers the rotational inertia of the internal gear, and makes the motor drive more efficient and energy consumption lower.
[0011] The diameter of the worm is greater than the width of the worm wheel, resulting in a larger contact area for the threaded connection. This disperses the load, reduces tooth surface wear, and improves transmission smoothness. The width of the annular slider is smaller than the width of the internal gear, reducing interference between the annular slider and the edge of the internal gear caused by excessively large annular slider width.
[0012] According to another aspect, at least one embodiment of this disclosure also provides an antenna signal generator, including: a generator rotation mechanism, the generator rotation mechanism including a support, the bottom of the support being fixedly connected to the top of a sleeve, a second rotating shaft being rotatably connected to the side of the support, a first bevel gear being fixedly connected to the circumferential surface of the second rotating shaft, the first rotating shaft passing through the sleeve and the support, a second bevel gear being fixedly connected to one end of the first rotating shaft, the first bevel gear and the second bevel gear meshing with each other, a connecting rod being fixedly connected to the circumferential surface of the second rotating shaft, and a generator disk being fixedly connected to the end of the connecting rod away from the second rotating shaft.
[0013] For example, in an antenna signal generator provided in at least one embodiment of this disclosure, a locking sleeve is fixedly connected to both ends of the second rotating shaft. The number of locking sleeves is set to two, and they are symmetrical to each other along the vertical central axis of the second rotating shaft. They can respectively abut against the two end faces of the second rotating shaft to prevent it from moving along the axial direction and ensure the accurate meshing position of the bevel gear set.
[0014] The bevel gear one has circular spokes on its side. The number of circular spokes is set to a certain amount and is arranged in a circumferential array on the side of the bevel gear one to avoid excessive local stress and deformation of the bevel gear one, and to ensure the meshing accuracy with the bevel gear two.
[0015] The bevel gear two has circular spokes on its side. The number of circular spokes is set to several and arranged in a circumferential array on the side of the bevel gear two, which reduces the material usage and weight of the bevel gear two, improves fatigue resistance, and is suitable for high-frequency rotation scenarios.
[0016] The number of teeth of the first bevel gear is equal to the number of teeth of the second bevel gear, ensuring that the rotational speed matches when adjusting the antenna azimuth and elevation angles, thus avoiding angle deviation. One end of the connecting rod is fixedly connected to a locking sleeve to prevent the generator disk from falling off.
[0017] The working principle and beneficial effects of this utility model are as follows:
[0018] 1. In this utility model, the worm gear, worm shaft, and internal gear components inside the circumferential rotation mechanism work together to drive the annular slider to slide along the slide groove, causing the sleeve to perform circumferential motion. This enables circumferential rotation, expanding the signal coverage area. The gear transmission structure is stable and has high transmission accuracy. The annular slider and slide groove work together to ensure smooth rotation. The structure is compact, installed inside the housing, saving space. Rotation is controlled by a motor, facilitating automated adjustment of the signal transmission direction.
[0019] 2. In this utility model, the bevel gear one, rotating shaft two, and connecting rod and other components inside the generator rotating mechanism cooperate with each other. By utilizing the power of the circumferential rotating mechanism, the meshing of bevel gear one and bevel gear two achieves vertical rotation, expanding the signal transmission angle range. The dual rotational degrees of freedom make the signal coverage more comprehensive and improve the signal transmission effect. The structural design of the connecting rod and generator disk ensures stability. The locking sleeve prevents loosening. The round hole spokes reduce weight while ensuring strength. The overall structure is compact, making full use of space and achieving efficient multi-angle signal transmission adjustment. Attached Figure Description

[0027] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.
[0028] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0031] like Figures 1-5 As shown, it illustrates an antenna signal generator according to an embodiment of the present disclosure, including: a housing 1, a support foot pad 2 fixedly connected to the bottom of the housing 1, a control panel 3 provided on the side of the housing 1, a switch button 4 provided on the side of the control panel 3, and a circumferential rotation mechanism 5 provided inside the housing 1.
[0032] The circumferential rotation mechanism 5 includes a motor 51, the bottom of which is fixedly connected to the inner side of the housing 1. A worm 52 is fixedly connected to the end of the output shaft of the motor 51. A rotating shaft 53 is rotatably connected to the inner side of the housing 1. A worm wheel 54 is fixedly connected to the circumferential surface of the rotating shaft 53. The circumferential surface of the worm 52 is threadedly connected to the circumferential surface of the worm wheel 54. An external gear 55 is fixedly connected to the circumferential surface of the rotating shaft 53. An annular slider 56 is slidably connected to the inner side of the housing 1. An internal gear 57 is fixedly connected to the side of the annular slider 56. The external gear 55 and the internal gear 57 mesh with each other. A sleeve 58 is fixedly connected to the top of the internal gear 57.
[0033] In some examples, the inner side of the housing 1 is provided with a groove, and the side of the annular slider 56 is slidably connected inside the groove. The groove provides a precise sliding path for the annular slider 56, ensuring that the internal gear 57 and the sleeve 58 rotate along a fixed circumferential trajectory, avoiding deviation or shaking.
[0034] The number of support feet 2 is set to several, and they are symmetrical about each other along the vertical central axis of the outer shell 1. They evenly bear the weight of the outer shell 1 and the internal mechanism, prevent the equipment from tilting or shifting the center of gravity, and ensure the stability during operation. The width of the annular slider 56 is equal to the width of the groove, which can prevent the annular slider 56 from wobbling left and right in the groove, and ensure that the internal gear 57 and the external gear 55 always maintain the correct meshing position, avoiding transmission errors or jamming.
[0035] The internal gear 57 has spokes on its side, and the number of spokes is set to several and arranged in a circumferential array on the side of the internal gear 57. This reduces the amount of material used while ensuring strength, reduces the rotational inertia of the internal gear 57, and makes the motor 51 drive more efficient and consumes less energy.
[0036] The diameter of the worm 52 is larger than the width of the worm wheel 54, resulting in a larger contact area for the threaded connection. This disperses the load, reduces tooth surface wear, and improves transmission smoothness. The width of the annular slider 56 is smaller than the width of the internal gear 57, reducing interference between the annular slider 56 and the edge of the internal gear 57 caused by excessive width.
[0037] For example, such as Figures 1-5As shown, the operator controls the motor 51 via the switch button 4 on the side of the control panel 3. The motor 51 drives the worm gear 52 to rotate, and the worm gear 52 meshes with the worm wheel 54, causing the rotating shaft 53 to rotate. The external gear 55, fixed to the rotating shaft 53, rotates accordingly. The external gear 55 meshes with the internal gear 57, driving the internal gear 57 to move in a circular motion along the groove on the inner wall of the outer casing 1. The sleeve 58 at the top of the internal gear 57 rotates synchronously. The annular slider 56 is embedded in the groove, which both restricts the axial displacement of the internal gear 57 and ensures smooth rotation. The diameter of the worm gear 52 is larger than the width of the worm wheel 54, enhancing transmission stability. The spoke design of the internal gear 57 reduces weight and optimizes load distribution. Through this mechanism, the antenna can achieve uniform circular scanning in the horizontal direction along with the sleeve 58, effectively expanding the signal radiation range.
[0038] like Figures 1-5 As shown, an antenna signal generator according to another embodiment of the present disclosure is illustrated, including: a generator rotation mechanism 6, the generator rotation mechanism 6 including a support 61, the bottom of the support 61 being fixedly connected to the top of the sleeve 58, a second rotating shaft 62 being rotatably connected to the side of the support 61, a first bevel gear 63 being fixedly connected to the circumferential surface of the second rotating shaft 62, the first rotating shaft 63 passing through the sleeve 58 and the support 61, a second bevel gear 64 being fixedly connected to one end of the first rotating shaft 63, the first bevel gear 63 and the second bevel gear 64 meshing with each other, a connecting rod 65 being fixedly connected to the circumferential surface of the second rotating shaft 62, and a generator disk 66 being fixedly connected to the end of the connecting rod 65 away from the second rotating shaft 62.
[0039] In some examples, the shaft 62 is also fixedly connected to two locking sleeves at both ends. The locking sleeves are symmetrical about each other along the vertical central axis of the shaft 62 and can respectively abut against the two end faces of the shaft 62 to prevent it from moving axially and ensure the precise meshing position of the bevel gear set.
[0040] The side of bevel gear 63 has circular spokes with a number of them, which are arranged in a circumferential array on the side of bevel gear 63 to prevent excessive local stress and deformation of bevel gear 63 and to ensure the meshing accuracy with bevel gear 64.
[0041] The bevel gear 264 has circular spokes on its side. The number of circular spokes is set to a certain number and is arranged in a circumferential array on the side of the bevel gear 264. This reduces the material usage and weight of the bevel gear 264, improves fatigue resistance, and is suitable for high-frequency rotation scenarios.
[0042] The number of teeth of bevel gear 63 is equal to the number of teeth of bevel gear 64, ensuring that the rotational speed matches when adjusting the antenna azimuth and elevation angles, thus avoiding angle deviation. One end of the connecting rod 65 is fixedly connected to a locking sleeve to prevent the generator disk 66 from falling off.
[0043] For example, such as Figures 1-5As shown, in the generator rotation mechanism 6, the power is provided by the rotating shaft 53 of the circumferential rotation mechanism 5. The rotation of the sleeve 58 drives the support 61 to rotate, and the rotation of the rotating shaft 53 drives the bevel gear 64 at the end to rotate accordingly, realizing the meshing with the bevel gear 63, converting the horizontal power into vertical rotation, realizing the swing of the generator disk 66 driven by the connecting rod 65 fixed to the rotating shaft 62. The circular hole spokes reduce the weight, and the locking sleeve fixes the two ends of the rotating shaft 62 to prevent movement. It realizes the dual-degree-of-freedom movement of horizontal rotation and pitch adjustment, enhances the three-dimensionality of signal coverage, provides multi-angle coverage of antenna signals, and meets the needs of dynamically adjusting the signal transmission direction.
[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
